Description

1 / 77 “ADAPTER ASSEMBLY AND FLUID DISTRIBUTION SYSTEM” Field of Invention

[001] The present invention generally relates to fluid dispensing systems for dispensing skin care and cleaning products, such as soaps, gels, disinfectants and the like. The invention is specifically directed to a dispenser adapter assembly to be used in the fluid dispensing system to enable the use of various types of disposable fluid dispensing packaging, refill containers and fluid pumps in one dispenser. The invention is also directed to a dispenser. Background of the Invention

[002] Fluid dispensers of various types are known. In particular, for dispensing cleaning products, such as soaps, there is a wide variety of manually or automatically operated pumps that dispense a certain amount of the product into the user's hand.

[003] Consumer products may include a dispensing outlet as part of the packaging, activated by a user pressing the top of the packaging. Such packaging uses a dip tube that extends below the liquid level and a piston pump that draws the liquid in and dispenses it downwards through an outlet nozzle.

[004] Commercial dispensers often use inverted dispensing containers that can be placed in dispensing devices, fixed to walls, or embedded in bathroom counters or similar. The pump may be integrated as part of the dispensing container or may be part of the permanent dispensing device, or both forming a fluid dispensing package. Such devices are robust and, if fixed to the wall, there is greater freedom in the direction and amount of force. Petition 870260066011, dated 03 / 07 / 2026, page 11 / 186 2 / 77 required for activation.

[005] A dispensing system that uses a pump to dispense a unit dose of liquid from an inverted collapsible container was described in WO 2009 / 104992. The pump consists of only a few elements with a resilient pumping chamber and regulating valves. The pump operates by applying a lateral force to the pumping chamber, causing it to partially collapse and expel its contents through the outer valve. Refilling of the pumping chamber occurs through the inner valve once the lateral force is removed. The filling force is provided by the inherent resilience of the pumping chamber wall, which must be sufficient to overcome any back pressure due to resistance to the collapse of the container.

[006] Other dispensing systems use an axial force to drive the pump, that is, directed in alignment with the direction in which the fluid is dispensed.

[007] In many cases, different dispensing systems with different types of fluid dispensing packages and different types of pumps may be used in a given location, for example, a building may have a mix of dispensers for use with different dispensing packages, requiring in turn having different types of fluid dispensing packages in stock rather than just one type in stock. Consequently, it would be desirable to provide a dispensing system that could operate in different dispensing operation solutions, for example, in axial dispensing operation solutions as well as lateral dispensing operation solutions. Description of the Invention

[008] It is desirable to have a distribution system that is flexible in its manner of operation and reliable when used so as to allow Petition 870260066011, dated 03 / 07 / 2026, page 12 / 186 3 / 77 different types of fluid dispensing packaging that are simple, hygienic, environmentally acceptable, and economical to produce.

[009] The invention relates, in particular, to an adapter assembly according to claim 1 and a fluid dispensing system according to claim 14 and a dispenser. Embodiments are set forth in the appended dependent claims, the following description and the drawings.

[0010] Thus, an adapter set is disclosed for use in a dispenser for a fluid dispensing package from a replaceable fluid container comprising a fluid reservoir and a fluid pump. The dispenser comprises an enclosure and a compartment for containing the fluid container. The dispenser has a front portion, a rear portion, and upper and lower end portions. The lower end portion forms a dispensing end portion of the dispenser and comprises a user actuator, by which the dispenser is operated to dispense a dose of a fluid from the fluid container through a nozzle in the lower end portion.

[0011] The dispenser compartment is designed to receive a fluid container having a pump of the first type being an axially compressible pump and the actuator has an engagement portion to drive the pump of the first type by compressing it axially in the vertical direction.

[0012] The adapter assembly is used in conjunction with the dispenser to allow the use of a fluid container having a pump of a second type inside the dispenser, the second type being driven by side compression.

[0013] The adapter assembly comprises a drive piece that is movable between a non-driven position and a fully driven position when mounted on the dispenser. The drive piece Petition 870260066011, dated 03 / 07 / 2026, page 13 / 186 4 / 77 comprises a first contact surface for contacting the user actuator and a second contact surface for contacting the pump of the second type. A user force (P) applied to the user actuator displaces the drive piece of the adapter assembly, when mounted on the dispenser, from its non-actuated position towards an actuated position, thus transferring a drive force (TF) from the drive piece through the second contact surface to the pump of a fluid container, when mounted in the compartment with the adapter assembly. The pump becomes laterally compressed to cause the fluid to be dispensed from the fluid container.

[0014] The adapter set also includes a first connection bracket for removable connection of the drive unit to the dispenser and / or fluid container mounted in the compartment.

[0015] As used in this document, an axial force for pump actuation is understood to be a force directed in alignment with the direction in which the fluid is dispensed. Similarly, a lateral force is understood to be a force substantially perpendicular to the direction in which the fluid is dispensed.

[0016] As used in this document, the terms “horizontal”, “lateral” and “vertical”, “upper” and “lower”, “downward” and “upward”, “front” and “rear” and “upper” and “lower” or similar terms should be understood as seen when a dispensing system with a dispenser and a fluid container is arranged for use, with or without the adapter assembly.

[0017] The fluid container can be adapted to be filled with a liquid such as, for example, liquid soap, foaming soap, alcohol gel, disinfectant or antibacterial liquid, or lotion. The flexible dispensing portion can be filled with the relevant liquid and subjected to a force. Petition 870260066011, dated 03 / 07 / 2026, page 14 / 186 5 / 77 external for dispensing the liquid. The pumps described herein may be of such a size that a suitable or desired volume, for example, 1 milliliter, of liquid may be dispensed when performing a complete dispensing stroke.

[0018] Suitable materials for forming the actuator assembly may be aluminum or any suitable plastics, such as olefin plastics, for example, polyethylene or polypropylene. The adapter assembly may be formed by injection molding, 3D printing or any other suitable method known to those skilled in the art. The materials mentioned and the assembly formation may be used for all parts of the adapter assembly and a combination of materials may also be considered for the adapter assembly or parts thereof.

[0019] Thus, the adapter set enables a dispensing system that can operate in different dispensing solutions, i.e., in axial dispensing solutions as well as lateral dispensing solutions. The adapter set makes the dispensing system flexible in its use and reliable when used in such a way as to allow the use of different types of fluid dispensing packaging, while also being simple, hygienic, environmentally acceptable and economical to produce.

[0020] The adapter set may include a second connection bracket for removable connection of the fixed cart to the dispenser and / or fluid container mounted in the compartment.

[0021] The first connection support can also be configured to connect the fixed cart to the dispenser and / or fluid container mounted in the compartment in a removable manner.

[0022] The pump of the second type may have a resilient pumping chamber. The resilient pumping chamber may be an elongated and elastic tube chamber that extends downwards in the lower portion of the fluid container in a direction from the bottom of the fluid reservoir to Petition 870260066011, dated 03 / 07 / 2026, page 15 / 186 6 / 77 a nozzle for the flexible tube chamber.

[0023] The user actuator may be a user lever configured to rotate around a first pivot.

[0024] In addition, the user lever may extend from the pivot towards a user operating portion of the user lever, wherein the user actuator has a surface facing the compartment and is configured to abut the first contact surface of the actuating part.

[0025] The user lever can extend downwards from the first pivot.

[0026] The drive piece may comprise an elongated arm extending in a substantially longitudinal direction (L1) from the same between two opposite ends of the arm, wherein the first end is connected to the first connecting support and the second end has a drive head. The head may be movable between the non-actuated position and the fully actuated position, wherein the drive head comprises the second contact surface for contacting the pump of the second type and the first contact surface for contacting the user actuator.

[0027] The elongated arm with the drive head provides a flexible and reliable drive piece that can be shaped and sized for the desired use, for example, it can be shaped and sized for the specific desired position of the contact surfaces as well as for a desired volume to be dispensed.

[0028] The drive head may project outward from the second end of the arm in at least one direction (W; X) forming an angle with the longitudinal direction (L1) of the elongated arm.

[0029] The drive head may have a dimension in a Petition 870260066011, dated 03 / 07 / 2026, page 16 / 186 7 / 77 first direction (W) extending perpendicularly to the longitudinal direction (L1) of the elongated arm from the first contact surface to the second contact surface which is larger than one dimension of the drive head in a second direction being parallel to a direction being perpendicular to the longitudinal direction and to the first direction (W).

[0030] This provides a means of forming a flat drive head with elongated contact surfaces providing proper distribution while ensuring there is space for it in the dispenser.

[0031] According to one embodiment, the drive element can be movably connected to the first connecting support. The drive element can be articulatedly fixed to the first connecting support and configured to rotate around a second pivot.

[0032] This allows the drive element to move between a non-driven position and a driven position in a lateral direction towards the cart and the rear of the dispenser. The pivot can be formed by a snap-fit ​​connection between the first connecting support and the drive element or it can, for example, be formed by a hinge connection or by a live hinge.

[0033] The drive piece may comprise an elongated arm that extends substantially in a longitudinal direction (L1) from the same between two opposite ends of the arm, as described above, and the first end of the elongated arm may be articulated to the first connecting support and configured to rotate around the second pivot to allow movement of the drive head between the non-driven position and the fully driven position.

[0034] According to another embodiment, the elongated arm may be a flexible arm to allow movement of the drive head. Petition 870260066011, dated 03 / 07 / 2026, page 17 / 186 8 / 77 between the non-engaged position and the fully engaged position.

[0035] This allows the drive element to move between a non-driven position and a driven position in lateral motion towards the carriage and the rear portion of the dispenser. The arm can be fixedly connected to the first connection support and partially or completely flexed from the non-driven position to the fully driven position. Those skilled in the art understand that the arm can be flexed using an elastic and flexible plastic material, for example, olefin plastics such as polypropylene, and by selecting shapes and dimensions suitable for the purpose.

[0036] Thus, the arm can be made of an elastic material such as polyethylene or polypropylene and be dimensioned so that it is flexible and elastic.

[0037] The fixed trolley has a trolley surface for resting against and receiving the pump, and the trolley surface is oriented towards the drive element. The trolley surface may comprise a recessed surface portion.

[0038] A recessed surface portion provides a cavity to house a portion of the pump that has a shape and dimensions suitable for fitting into the cavity. The cavity may also provide the possibility of allowing a portion of the drive element to move into the cavity when the drive element is moved to a drive position.

[0039] The recessed surface portion may be concave. Such a concave surface portion may, in shape, fit the cavity to an elongated and elastic tube chamber.

[0040] The concave surface portion may constitute the cart surface.

[0041] The concave surface may be concave in a horizontal plane and may form a recess that extends vertically to accommodate Petition 870260066011, dated 03 / 07 / 2026, page 18 / 186 9 / 77 a portion of the pump. In this way, the concave surface portion can match the shape of the pump's external shape, particularly the elongated and elastic tube chamber. Thus, the recess can have a width in a horizontal plane that is equal to or greater than an external lateral width of the pump portion configured to be housed in the recess.

[0042] The recess that extends vertically may have a maximum width in a superior horizontal plane in an upper portion of the fixed carriage that is greater than the maximum width of the recess in a inferior horizontal plane in a lower portion of the fixed carriage. In this case, the second contact surface of the drive head may have a second upper contact surface portion facing the upper portion of the recess when the drive part is in the fully driven position. The second contact surface may, in this case, have a second lower contact surface portion facing the lower portion of the recess when the drive part is in the fully driven position, i.e., when the lower contact surface portion has been moved to its position closest to the fixed carriage.

[0043] This can allow the pump to move into the cavity during distribution, so that the pump is compressed and distorted in a different way along the length of the pump for proper and reliable fluid distribution.

[0044] The second contact surface of the drive part may have a maximum lateral width such that it can be received at least partially in the recessed surface portion. In other words, this means that the second contact surface of the drive part may have a width in a horizontal plane that is less than the width of the cavity formed by the recessed surface portion of the carriage surface in the horizontal plane. This allows the drive part to move at least Petition 870260066011, dated 03 / 07 / 2026, page 19 / 186 10 / 77 partially into the cavity when the drive piece is moved to the drive position, thus deforming the pump in the recess.

[0045] At least one portion of the fixed carriage surface may form a recessed surface portion being concave and in the form of a hollow half of a cone that tapers in a direction from an upper end to a lower end of the adapter assembly.

[0046] The term hollow here means that the cone, a semi-cylinder or similar has open ends.

[0047] By forming a recessed surface portion adopting the shape of half a cone, a cavity is provided for the pump to be received within, as well as easy and smooth insertion of the fluid container into the dispenser that carries the adapter assembly. The tapered surface portion guides the pump from the fluid container to the position it should have in the dispenser, that is, to be located between the drive piece and the fixed carriage.

[0048] In addition, at least one lower portion of the fixed carriage may form a recessed surface portion that is concave and forms a hollow semicylinder.

[0049] The recessed surface portion in the form of the hollow semi-cylinder allows for the possibility of a form-fitting stop with the pump type being the elongated and elastic tube chamber.

[0050] The uppermost portion of the fixed cart's surface may form the recessed surface portion in the form of a hollow half of a cone, and the lower portion of the fixed cart may form the recessed surface portion in the form of a hollow semicylinder.

[0051] The adapter assembly can be configured so that at least a portion of the second contact surface touches the pump in Petition 870260066011, dated 03 / 07 / 2026, page 20 / 186 11 / 77 position not engaged.

[0052] The second contact surface can touch the pump in the non-actuated position in a pre-tensioned manner.

[0053] The possibility of this support can be provided by equipping the drive piece with an elastic and flexible arm that has a resting position so that at least a portion of the drive head is received within the recessed surface portion. When the pump is inserted between the fixed carriage and the drive head, the elastic and flexible arm moves forward to the non-driven position, in which the drive head rests against the pump in a pre-tensioned manner.

[0054] A central portion of the second contact surface may extend at an angle to the vertical direction in a non-actuated position.

[0055] An upper end portion of the second contact surface may abut the pump in the non-driven position and extend from the abutment point downwards and forwards to a lower end portion of the second contact surface. The second contact surface may, in this case, extend substantially in the direct vertical direction in a driven position. During the use of the adapter in the distribution system, this allows for gradual compression and deformation of the pump from an upper portion to a lower portion thereof.

[0056] In this case, the contact between the second contact surface and the pump gradually increases from the non-driven position to the fully driven position. The contact can gradually increase downwards from the upper end portion of the second contact surface to the lower end portion of the second contact surface. This allows for reliable dispensing operation, where the fluid is dispensed in a controlled manner with a low risk of fluid backflow within the pump, since Petition 870260066011, dated 03 / 07 / 2026, page 21 / 186 12 / 77 The upper end portion of the second contact surface first makes contact with the pump and closes the chamber to prevent any backflow of fluids into the pump.

[0057] The adapter assembly may include one or more stabilizers to prevent lateral movement and / or tilting of the adapter assembly during use, for example, in the form of protrusions extending from the bottom of the first connection bracket and configured to rest on the inner surface (-s) of the dispenser.

[0058] The adapter assembly may further comprise a fluid container holder configured to be received into the dispenser compartment to hold the fluid container in a desired position within the dispenser compartment.

[0059] The fluid container holder provides proper retention and positioning of the fluid container in the dispenser.

[0060] The fluid container support can form the first connection support.

[0061] The fluid container support can form the second connection support.

[0062] The fluid container support may comprise one or more means of positioning the fluid container to engage one or more corresponding connecting portions of the fluid container and prevent axial and / or rotational movement of the fluid container in the dispenser.

[0063] The adapter assembly may further comprise one or more positioning means for engaging one or more corresponding connectors in the dispenser and preventing axial and / or rotational movement of the adapter assembly in the dispenser. The adapter assembly may also comprise one or more positioning means for preventing incorrect positioning of the adapter assembly in the dispenser. Petition 870260066011, dated 03 / 07 / 2026, page 22 / 186 13 / 77

[0064] The positioning means may be one or more pins or protruding lugs to fit into one or more corresponding recesses in the dispenser and / or to prevent incorrect positioning of the adapter assembly in the dispenser.

[0065] According to another embodiment, the first connection support may be an elastic and flexible element with a recess having a larger lateral dimension than the pump has in the lateral direction, and in which the drive piece and the fixed carriage are carried by the element and form portions that project from the opposite side within the recess, so that the pump of the second type may be configured between the second contact surface of the drive piece and the fixed carriage, in which the elastic element is safely deflected towards the pump in the non-driven position and when a user force (P) is applied to the user actuator, the element is compressed towards the carriage so that the pump is compressed laterally between the second contact surface and the fixed carriage, causing the fluid to be dispensed from the fluid container.

[0066] The elastic and flexible element may have a circular shape with a central passage opening forming the recess.

[0067] In addition, an adapter set is provided for use in a dispenser for a replaceable fluid container. The adapter set comprises a drive piece connected to a first connection bracket for removable connection of the adapter set to the dispenser. The drive piece comprises a first contact surface for contacting the user actuator of a dispenser and a second contact surface for contacting a fluid pump. The adapter set further comprises a fixed carriage connected to the first connection bracket and having a carriage surface for contacting and receiving the pump, wherein the fixed carriage and the drive piece Petition 870260066011, dated 03 / 07 / 2026, page 23 / 186 14 / 77 drives are connected to one side of the first connecting support, where the carriage surface faces the drive part.

[0080] The second contact surface may have a maximum lateral width so that it can be received at least partially on the recessed surface portion.

[0081] The drive part may include a flexible, elastic arm that has a rest position such that at least a portion of the drive head is received within the recessed surface portion.

[0082] At least one portion of the cart's surface may form a recessed surface portion being concave and in the form of a hollow half of a cone that tapers in a direction from an upper end to a lower end of said recessed surface portion.

[0085] The adapter assembly can also be configured so that a central portion of the second contact surface extends at an angle in the vertical direction in a non-actuated position.

[0086] The adapter assembly may also include one or more stabilizers to prevent lateral movement and / or tilting of the adapter assembly during use.

[0087] The first connection support can form a support of Petition 870260066011, dated 03 / 07 / 2026, page 26 / 186 17 / 77 fluid container configured to be received in the dispenser compartment to keep the fluid container in a desired position in the dispenser compartment.

Description of the Invention's Implementation

[00103] The fluid distribution system and adapter assembly according to the invention will be exemplified herein by some exemplary embodiments. However, this disclosure should not be interpreted as limited to these exemplary embodiments. Other embodiments of the fluid distribution system and adapter assembly may also be considered within the scope of the appended claims. The disclosed features of the exemplary embodiments may be combined as readily understood by a person skilled in the art to which this invention pertains. Similar numbers refer to similar elements throughout. Well-known functions or constructions will not necessarily be described in detail for brevity and / or clarity.

[00104] Figure 1 shows a perspective view of a fluid dispensing system (1) in which the present invention, as claimed in the appended claims, can be implemented. The dispensing system (1) includes a reusable dispenser (100) of the type used in toilets and similar facilities available under the name Tork™ from Essity Hygiene and Health AB. The dispenser (100) is described in greater detail in document WO 2011 / 133085, the contents of which are incorporated herein by reference in their entirety. It will be understood that this embodiment is merely illustrative and that the present invention can also be implemented in other dispensing systems.

[00105] The dispenser (100) includes a rear portion (110) and a front portion (112) that fit together to form a closed enclosure (116) that can be secured using a latch (118) on an upper end portion (101) of the dispenser (100). The enclosure (116) is fixed to a wall or Petition 870260066011, dated 03 / 07 / 2026, page 35 / 186 26 / 77 another surface by a support portion (120). On a lower end portion (102) of the dispenser and a lower side of the housing (116) is an actuator (124), by which the dispensing system (1) can be operated manually to dispense a dose of cleaning fluid or similar.

[00106] Figure 2 shows in perspective the dispenser (100) with the housing (116) in the open configuration and with a replaceable and dispensable fluid container (200) contained in a compartment (150) therein. The replaceable fluid container (200) comprises a fluid reservoir (250) and a fluid pump (300). The reservoir (250) is a 1000 ml collapsible reservoir of the type described in WO 2011 / 133085 and also in WO 2009 / 104992, the contents of which are also incorporated herein by reference in their entirety. The reservoir (250) is generally cylindrical in shape and is made of polyethylene. Those skilled in the art will understand that other volumes, shapes and materials are equally applicable and that the reservoir (250) can be adapted according to the shape of the dispenser (100) and according to the fluid to be dispensed.At the lower end portion of the dispenser (100) is a pump (300) for the fluid container (200), which is activated by a user manually pushing a user operating portion of the actuator (124) to press the pump and dispense the fluid from the container.

[00107] The present invention relates to a fluid distribution system (1) and an adapter set to allow the use of different fluid containers (200) with different types of pumps (300).

[00108] A fluid container (200) with a pump (300a) of a first type is designed to be received in the compartment (150) of the dispenser (100) without the use of an adapter set. The pump of a first type is an axially compressible pump (300a) and the actuator (124) of the dispenser (100) has a coupling portion to actuate the pump (300a) of the first type by compressing it axially in a vertical direction towards the Petition 870260066011, dated 03 / 07 / 2026, page 36 / 186 27 / 77 upper end portion (101) of the dispenser (100).

[00109] A fluid container (200) with a pump (300b) of a second type requires the use of an adapter assembly of the invention. The adapter assembly adapts the compartment (150) to be sized to receive a fluid container (200) having a pump of a second type inside the dispenser (100) so as to allow the pump of the second type to be actuated by lateral compression to cause the fluid to be dispensed from the fluid container. The actuator (124) can move a drive piece of the adapter assembly towards the pump (300b) of the second type and laterally compress the pump.

[00110] Figure 3 shows the fluid container (200) with the pump (300a) of the first type in side view. As can be seen, the reservoir (250) includes two portions. A hard portion (210) and a soft portion (212). Both portions (210, 212) are made of the same material, but with different thicknesses. As the reservoir (250) empties, the soft portion (210) collapses into the hard portion (212) as the liquid is dispensed by the pump assembly (300a). This construction avoids the problem of a vacuum buildup inside the reservoir (250). Those skilled in the art will understand that, although this is an example of the reservoir shape, other types of reservoirs can also be used in the context of the present invention, including, but not limited to, bags, pouches, cylinders and the like, both closed and open to the atmosphere.The container can be filled with soap, detergent, disinfectant, skin care formulation, moisturizers, or any other suitable fluid and even medications. In most cases, the fluid will be aqueous, although those skilled in the art understand that other substances may be used when appropriate, including oils, solvents, alcohols, and the like. Furthermore, although reference is made to liquids below, the dispenser (100) can also dispense fluids such as dispersions. Petition 870260066011, dated 03 / 07 / 2026, page 37 / 186 28 / 77 suspensions or particles.

[00111] On the lower side of the fluid container (200), a pump (300a) of the first type is provided, having an external configuration that substantially corresponds to that described in WO 2011 / 133085. The fluid container has a rigid neck (214) provided with a connecting flange (216). The connecting flange (216) engages with a stationary sleeve (310) of the pump assembly (300a). The pump assembly (300a) also includes a sliding sleeve (312), which terminates in an orifice (318). The sliding sleeve (312) carries a drive flange (314) and the stationary sleeve has a locating flange (316). Both sleeves (310, 312) are injection molded from polycarbonate, although a person skilled in the art will be well aware that other relatively rigid moldable materials may be used.In use, as will be described in more detail below, the sliding sleeve (312) is movable in an axial direction A by a distance D relative to the stationary sleeve (310) to perform a single pumping action.

[00112] Figures 4A and 4B show partial cross-sectional views through the dispenser (100) of Figure 1, illustrating the pump (300a) of the first type in operation. According to Figure 4A, the locating flange (316) rests on the front and rear shelves (130, 131) and is engaged by a locating groove (135) formed between the rear shelf (131) and a pin (136) in the rear portion (110). The actuator (124) is rotated on the first pivot (132) to the front portion (112) and includes an engagement portion (134) that engages below the drive flange (314).

[00113] Figure 4B shows the position of the pump (300a) of the first type once a user has exerted a force (P) on the actuator (124). In this view, the actuator (124) has rotated counterclockwise around the first pivot (132), causing the engagement portion (134) to act against the drive flange (314) with a force (F), causing it to move upwards. Petition 870260066011, dated 03 / 07 / 2026, page 38 / 186 29 / 77 Up to now, the fluid distribution system (1) comprising a fluid container (200) with a pump (300b) of the first type and its operation can be essentially the same as that of the known existing system of WO 2011 / 133085.

[00114] The fluid dispensing system (1) has thus far been described with a view to using the dispenser (100) in conjunction with the fluid container (200) with a pump (300a) of the first type. It is desirable to be able to use the fluid container (200) with a pump (300b) of the second type in the dispenser (100) described above without affecting the possibility of still being able to load the dispenser (100) with a fluid container (200) having a pump (300a) of the first type. A removable adapter assembly according to the present invention provides this possibility. The fluid dispensing system (1), the dispenser and the adapter assembly will now be exemplified in more detail with reference to the accompanying drawings and various examples of embodiments.

[00115] Figure 5 shows a perspective view of a fluid container (200) with a pump of a second type. As can be seen, the reservoir (250) is, for simplicity, shown to be of a generally cylindrical shape. However, those skilled in the art will understand that the reservoir (250) may have the same construction described above in relation to the fluid container (200) shown in Figure 3. Those skilled in the art will also understand that any other type of reservoir (250) described above that may be used with the container (200) shown in Figure 3 may also be used in the context of the fluid container (200) with the pump of a second type. The container (200) may be filled with fluids such as soap, detergent, disinfectant, skin care formulation, moisturizers, or any other suitable fluid, as mentioned above in relation to Figure 3. Petition 870260066011, dated 03 / 07 / 2026, page 39 / 186 30 / 77

[00116] On the lower side of the fluid container (200), a pump (300b) of the second type having an external configuration of an elongated, elastic tube forming a resilient pump chamber (300b) is provided. The chamber is in fluid communication with an interior of the fluid reservoir and is connected to a rigid neck (214a) of the fluid reservoir by a connector cap (360) to connect and seal the fluid reservoir to the chamber (300b). A nozzle (365) is provided at the lower end of the chamber. A valve may be disposed in the chamber (300b) near the nozzle (365) to prevent liquid from dripping out of the fluid container when the chamber is not squeezed. Similarly, a valve may be disposed between the chamber (300b) and the fluid reservoir to prevent liquid from being forced back into the reservoir when the chamber is being squeezed. Such valves are known in the art.An example of a pump of this type and an example of a connection from the pump to the fluid reservoir are described in WO 2009 / 104992. Those skilled in the art will understand that, although the elongated and elastic tube chamber (300b) is an example of a pump (300b) of the second type, other types of pumps of the second type may also be used in the context of the present invention, including a pump (300b) of a flexible or resilient pump chamber of forms other than an elongated and elastic tube chamber (300b).

[00117] Figures 6A-6C show one embodiment of an adapter assembly (400) for use with a fluid container (200) with a pump (300b) of the second type, in particular the fluid container (200) with the elongated elastic tube chamber (300b) as shown in Figure 5.

[00118] The actuator assembly comprises a connection support forming the first connection support (410) of the present invention for removable connection of the actuator assembly to the distribution system. Petition 870260066011, dated 03 / 07 / 2026, page 40 / 186 31 / 77 fluid (1). As shown in Figures 6A-6C, the first connection support (410) is a disc-shaped plate (410; 470) with a central through-opening (412) through the main plane of the plate. The plate has an external shape and dimensions to allow it to rest on a dispenser seat (100) formed by the shelves (130 and 131) of the dispenser (100), as well as to be engaged with the locating groove (135) on the rear shelf (131) in the rear portion (110) of the dispenser (100) as described herein in relation to Figures 3 and 8A-8C. The thickness of the plate is also selected to correspond to the engagement means described in more detail below, see Figures 8A-8C. The first illustrated connection support (410) also forms a fluid container support (470) configured to be received in the compartment (150) of the dispenser (100) to hold the fluid container (200) in a desired position in the compartment (150) of the dispenser (100).This is provided by the central through-opening (412) having a circular shape that matches the dimensions and shape of the connector cover (360) as shown in Figure 5. The plate forms a seat for the connector cover (360) to rest upon, wherein a laterally projecting flange (368) set at the upper end of the connector cover (360) contacts and rests upon a portion of an upper surface (435) of the plate near the through-opening (412) thereof and the remaining portion (367) of the connector cover (360) below the flange (368) is set to project downwards through the through-opening (412) of the plate. See Figures 5 and 6A-6C.

[00119] Those skilled in the art will understand that, although the disc-shaped plate (410; 470) with the central passage opening (412) is an example of a first connection support (410) as well as a fluid container support (470) to be used in the context of the present invention, other types of first connection supports (410) and fluid container supports Petition 870260066011, dated 03 / 07 / 2026, page 41 / 186 32 / 77 (470) for the fluid container (200) may be used in the context of the illustrated adapter assembly (400), including first connection supports of forms other than the disc-shaped plate with the central passage opening (412), including, but not limited to, plates having in part a circular shape with two or more straight edges or an external polygonal shape, such as a hexagonal or octagonal shape, still having portions supported on the seat of the dispenser shelves (130 and 131) (100). The person skilled in the art also appreciates that the circular passage opening (412) may adopt other forms, including, but not limited to, a polygonal shape which may still form the seat for the fluid container (200) and the connector cover (360) or similar.The person skilled in the art also understands that the plate may take forms such as one or more U-shaped plates or similar forms taking the circular form that the dispenser (100) has in the area of ​​the shelves (130; 131), for example, two C-shaped plates, each configured to rest on its respective shelf (130; 131) and having an external form matching the surrounding dispenser. These plates may be held together by one or more connecting means or portions, being disposed under or over the plates and connected to suitable plate surfaces.

[00120] The adapter assembly (400) further comprises a drive piece (420), as shown in Figures 6A-6C. The drive piece (420) includes an elongated arm (422) extending in a longitudinal direction (L1) between two opposite ends of the arm. The first end (424) is configured to form a snap-fit ​​connection (416) with a corresponding recess (414) in the disc-shaped plate in an area between an edge and the central opening (412) of the plate to allow the drive piece (420) to be connected to the first support connection (410). The arm (422) will then extend in a direction (L1) forming an angle with the main plane of the plate. A second end of the arm carries Petition 870260066011, dated 03 / 07 / 2026, page 42 / 186 33 / 77 an actuating head (426) comprising a first contact surface (427) for contacting the user actuator (124) and a second contact surface (428) for contacting the pump (300b) of the second type. The actuating head (426) projects outward from the second end of the arm in two opposite directions (W; X) being directions substantially perpendicular to the longitudinal direction (L1) of the elongated arm (422) to form the first and second contact surfaces (428; 427) facing away from each other. The first contact surface (427) is convex in its shape to allow contact with the actuator (124) in a manner conforming to the shape.

[00121] The snap-fit ​​connection (416) is configured to form a second pivot (418) in the fluid distribution system (1), wherein the drive piece (420) can rotate around the second pivot (418). The pivot function is provided by forming two tapered portions (423) on opposite sides of the arm near the first end (424) that fits into the recess (414) which is tapered on both sides of the plate, wherein a rotary movement of the arm (422) becomes possible along a plane. In this way, the drive piece (420) can rotate around the second pivot (418) and allow the head to be moved along a rotation direction (Z) between a non-driven position and a fully driven position, to allow the fluid to be dispensed from the fluid container (200), when the adapter assembly (400) is mounted on the dispenser (100) together with the fluid container (200).

[00122] Those skilled in the art will understand that, although the drive piece (420) being articulatedly connected to the connection support and having the drive head (426) is an example of a drive piece (420) being movably connected to the first connection support (410) and carrying the two contact surfaces (427; 428) for use with the pump (300b) of the second type, other drive pieces (420) of this type may be used, including, but not limited to, drive pieces of Petition 870260066011, dated 03 / 07 / 2026, page 43 / 186 34 / 77 drive formed with other head shapes, such as a head with a spherical shape and a second contact surface (428) being concave to match the shape of the pump or convex to better support the complete distribution of the fluid. The person skilled in the art also appreciates that other types of moving connections may be used, including, but not limited to, a second pivot (418) formed by a hinge connection or by a live hinge.

[00123] Instead of forming a hinged connection between the drive piece (420) and the first connecting support (410), the person skilled in the art also provides that the arm (422) can be fixedly connected to the first connecting support (410) and partially or completely made flexible from the non-driven position to the fully driven position in the same direction of rotation (Z), since the drive piece (420) is hingedly connected to the first connecting piece (410). The person skilled in the art understands that the arm (422) can be made flexible by using an elastic and flexible plastic material of olefin plastics, such as polypropylene, and by selecting shapes and dimensions suitable for the purpose.

[00124] As further shown in Figures 6A-6C, the adapter assembly (400) comprises a fixed carriage (430) configured to abut the pump (300b) of the second type when mounted in the fluid distribution system (1). The carriage (430) is fixedly connected to the plate-shaped disc on the same side of the plate as the drive piece (420), but on an opposite side of the central passage opening (412) of the plate (410). The carriage (430) comprises a support structure extending from the plate (410) in a direction perpendicular to the main plane of the plate (410) to one end with a projecting portion (432) thereof extending towards the drive piece (420) and having a carriage surface (434) configured to abut the pump (300b) of the second type, wherein the surface Petition 870260066011, dated 03 / 07 / 2026, page 44 / 186 35 / 77 of the carriage (434) is facing the drive piece (420). In this configuration, the pump (300b) of the second type can be positioned between the second contact surface (428) of the drive piece (420) and the fixed carriage (430). When a force is applied to the drive piece (420) to move the drive head (426) towards the pump, the pump (300b) is compressed between the second contact surface (428) of the drive head (426) and the carriage surface (434) causing the fluid to be dispensed from the pump. In Figures 6A-6C, the surface of the carriage (434) is shown as flat. The person skilled in the art understands that the surface of the carriage (434) can adopt any suitable shape to act as a fixed carriage (430) and match the second contact surface of the drive part (420), for example, the surface of the carriage (434) can adopt an inclined, rounded, convex or concave surface.The carriage (430) can be divided into several carriage portions or fixed carriages, each having a carriage surface (434). In this way, the fixed carriage (430) can be adjusted to provide the appropriate counterforce to the drive piece (420) to provide an appropriate distribution action.

[00125] A protruding pin (436) is provided on an outward-facing surface of the carriage surface (434). As will be further illustrated in Figures 8A to 8B and related description below, this pin (436) acts as a positioning means for engaging the corresponding recess (142) in the rear portion (110) of the dispenser (100) and this provides correct positioning of the adapter assembly (400) in the dispenser (100) during assembly of the fluid dispensing system (1). Thus, the recess (142) forms a connector for the pin (436). The engagement between the pin (436) and the recess (142) also prevents a rotational movement of the adapter assembly (400) in the dispenser (100), in which the adapter assembly (400) is mounted. A person skilled in the art understands that the means of Petition 870260066011, dated 03 / 07 / 2026, page 45 / 186 36 / 77 Positioning means may adopt any suitable form or shape that may assist in positioning the adapter assembly (400) in the dispenser (100) and in preventing any movement of the adapter assembly (400) in the dispenser (100), for example, by providing frictional contact between the adapter assembly (400) and the dispenser (100) or in any other ways that suitably prevents rotational and / or axial movement of the adapter assembly (400) mounted in the dispenser (100). Positioning means may also be configured in other parts of the adapter assembly (400). Other examples of positioning means will be described below.

[00126] The materials suitable for forming the actuator assembly (400) may be aluminum or any suitable plastics, such as olefin plastics, for example, polyethylene or polypropylene. The adapter assembly may be formed by injection molding, 3D printing or any other suitable method known to those skilled in the art. The materials mentioned and the forming of the adapter assembly (400) may be used for all embodiments described herein.

[00127] In addition, the described adapter set may have the following example dimensions. The circular plate may have an outer diameter of 50 mm and the diameter of the passage opening may be 31 mm. The thickness of the plate may be 4 mm, which provides retention by friction by the engagement means (140) described below. The drive piece extends from the plate with a length of 38 mm and the carriage extends from the plate with a length of 39 mm. The surface of the carriage has a width of about 12 mm and a height of about 13 mm. The second contact surface has a width of about 13 mm and a height of 9 mm. The diameter of the elongated and elastic tube chamber may be 14 mm and a length of the cap of about 56 mm. Petition 870260066011, dated 03 / 07 / 2026, p. 46 / 186 37 / 77

[00128] Figure 7 schematically illustrates an assembly of a fluid distribution system (1) including the dispenser (100) of Figure 1, a dispenseable container of Figure 5 and the adapter assembly (400) of Figures 6A-6C.

[00129] In the front portion (112) of the dispenser (100), the housing forms a front cover (113) which is articulated to the rear portion (110) at the lower end portion (102) thereof. The front cover (113) is opened by unlocking the latch (118) at its upper end and rotating the cover around its pivot at the lower end to expose the interior of the dispenser (100). At the lower end portion of the rear portion (110) is the portion for retaining fluid container (200) and the pump.The adapter assembly (400) is mounted on the dispenser (100) by inserting it through a retaining opening (139) to hold the fluid container (200) in the lower end portion (102) of the dispenser (100). This is best shown in Figures 8A-8C, showing enlarged views of the lower end portion of the interior of the dispenser (100) with and without the adapter assembly (400) inserted and secured in the dispenser (100) as seen from an angle above towards the rear portion (110) of the lower end portion (102). As shown in Figure 8A, the retention opening (139) is circular in shape, and the rear shelf (131) and the locating groove (135) formed between the rear shelf (131) and the pin (136) are arranged in the rear portion (110) as described above in relation to Figure 4A and the fluid container (200) with the pump (300a) of the first type.

[00130] As also shown in Figure 8A, the locating groove (135) extends rearward through an opening (137) formed in the wall of the rear portion (110) to form a positioning opening (137). The purpose of this positioning opening (137) will be explained in more detail below in relation to other embodiments of the assembly. Petition 870260066011, dated 03 / 07 / 2026, page 47 / 186 38 / 77 adapter (400).

[00131] Below the retaining opening (139) in the lower end portion (102) that forms the part for housing the fluid pump of a fluid container (200), the rear portion (110) has two vertical flanges (141a; 141b) that extend forward. These flanges form a positioning recess (142) between them. The adapter assembly (400) is inserted into the retaining opening (139) with the side of the first support / connecting plate (410) carrying the drive piece (420) and the fixed carriage (430) facing downwards towards the lower end portion (102) of the dispenser (100) and with the fixed carriage (430) being positioned towards the rear portion (110) of the dispenser (100).When the adapter is fully inserted, the first connection support (410) in the form of a plate rests on the front and rear shelves (130; 131) and engages with the locating groove (135) between the rear shelf (131) and the pin (136), see Figure 8B including its enlarged portion. Furthermore, the protruding pin (436) of the fixed carriage (430) engages with the positioning recess (142) formed by the vertical flanges (141a; 141b) on the rear portion (110) of the dispenser (100). This engagement provides correct positioning of the adapter assembly (400) in the dispenser (100) during insertion of the adapter assembly (400) into the fluid dispenser (100). The engagement between the pin (436) and the recess (142) also prevents rotational movement of the adapter assembly (400) in the dispenser (100).

[00132] As also shown in Figures 8A-8C, the dispenser (100) includes engagement means (140) for holding the disc-shaped plate in place in the dispenser (100). As the disc-shaped plate also forms the fluid container holder (470) in this embodiment, the provision of engagement means (140) also provides means for holding the fluid container holder (470) in place when inserting the fluid container (200) into the dispenser (100), using the dispenser (100) and removing the container from Petition 870260066011, dated 03 / 07 / 2026, page 48 / 186 39 / 77 fluid (200) from the dispenser (100). The person skilled in the art understands that the coupling means (140) now described can be used in conjunction with many of the fluid container holders (470) described herein.

[00133] The engagement means (140) comprises an element that can be moved between a non-retaining position and a retaining position. The illustrated engagement means (140) is a C-shaped element that is displaceable in a horizontal plane from the non-retaining position as shown in Figure 8B in a backward direction to the retaining position as shown in Figure 8C. In the retaining position, the engagement means (140) has portions (140a, 140b) that engage with the disc-shaped plate. The plate may have a thickness that allows the engagement means (140) to be locked in the retaining position by a frictional interaction with the plate. Those skilled in the art understand that the plate may also comprise a pattern of cutouts or protrusions that engage with the engagement means (140). Optionally, the engagement means (140) may also be held in its retaining position by other means, such as by the housing, as described below.

[00134] A person skilled in the art understands that the coupling means (140) can take various forms, for example, a bayonet-type coupling, a screw coupling, one or more movable jaws, or a “click” type coupling on the dispenser (100) to which the adapter assembly (400) or fluid container holder (470) engages. The coupling means (140) can be a fixed component of the dispenser (100) or it can be movable within the dispenser (100). If the coupling means (140) is movable within the dispenser (100), it can be sprung or otherwise resiliently arranged so that it is displaced after insertion of the adapter assembly (400) into the dispenser (100), but returns to an engaged position after correct placement of the adapter assembly (400). The coupling means (140) can also be manually activated as in the example shown. The coupling means (140) Petition 870260066011, dated 03 / 07 / 2026, page 49 / 186 40 / 77 may comprise one or more angled surfaces that promote the correct insertion and engagement of the adapter assembly (400) in the dispenser (100). The engagement means (140) may be resiliently suspended in the dispenser (100) so that when the housing (116) is open, the engagement means (140) is held in the open position by, for example, a spring. An adapter assembly (400) may be removed from the dispenser (100) and a new adapter assembly (400) may be placed in the dispenser (100). When the housing (116) is being closed, the engagement means (140) is pushed by the housing (116) against the spring into an engaged and retaining position, in which the adapter assembly is engaged.

[00135] As schematically illustrated in Figure 7, the next step in assembling the fluid distribution system (1) is to insert the fluid container (200) into the dispenser (100) now holding the adapter assembly (400). The fluid container (200) is inserted with its pump in an elongated form and elastic tube chamber (300b) into the central opening (412) of the fluid container holder (470) being the disc-shaped plate until the connector cap (360) of the fluid container (200) with its flange (368) rests on the seat formed by the adapter assembly (400) in the dispenser (100) as described above and also provided in Figure 9A. Figure 9A also illustrates that the fluid container (200) is inserted so that the elongated pump tube (300b) is placed between the second contact surface (428) of the drive piece (420) and the carriage surface (434) of the fixed carriage (430).

[00136] The assembly of the fluid distribution system (1) is then completed by closing the dispenser (100) by moving the top of the front cover to the rear portion (110) and, optionally, locking the cover in the rear portion. The dispenser (100) is then ready for use.

[00137] Figures 9A and 9B show a perspective view of Petition 870260066011, dated 03 / 07 / 2026, page 50 / 186 41 / 77 a lower end portion (102) of the fluid distribution system (1) of Figure 7, when mounted in a fluid distribution system (1) as shown in Figure 1, with a portion of the dispenser (100) cut away to show interior details of the fluid distribution system (1) in operation.

[00138] According to Figure 9A, the fluid container (200) rests in its seat in the dispenser (100) which is formed by the disc-shaped plate that forms the support of the fluid container (470) of the adapter assembly (400) being mounted in a removable manner in the dispenser (100). The fluid pump (300b) of the second type being an elongated and elastic tube chamber (300b) extends downwards from the fluid container (200) and between the second contact surface (428) of the drive piece (420) and the carriage surface (434) of the fixed carriage (430) to the nozzle (365) at the bottom of the dispenser (100). The nozzle (365) is placed in the lower part of the dispenser (100) in order to avoid the risk of having any dispensing part contaminated when dispensing any fluids from the fluid container (200), but at the same time not being clearly visible to a user when using the dispenser (100).The position of the nozzle (365) depends, for example, on the dimensions of the fluid container (200) and the position that the fluid container (200) can have in the dispenser (100). The person skilled in the art knows how to adapt the support of the fluid container (470) or its position in order to adjust the position of the nozzle (365). The adapter assembly (400) can also be modified to adjust its position relative to the pump (300b), as well as the shape of the pump (300b) and the maximum volume desired to be dispensed from the fluid container (200). Some examples of dimensions and shapes of the adapter assembly (400) were presented above for the embodiment now shown in Figure 9A. These dimensions and shapes can be provided for other embodiments shown in this document. For example, the dimensions of the drive head (426) and the fixed carriage (430) can be... Petition 870260066011, dated 03 / 07 / 2026, page 51 / 186 42 / 77 adjusted so that a pump (300b) of the second type placed between them in the dispenser (100) and in the non-actuated position must be in the uncompressed and undistorted form, and still providing sufficient dispensing when actuated. Optionally, the shapes and dimensions may be adjusted to allow the drive head (426) to rest on the pump (300b) in a pre-tensioned manner in the non-actuated position to allow immediate and adequate dispensing when the drive head (426) is moved to an activated position.

[00139] In Figure 9A, the actuator (124) is rotated on the first pivot (132) to the front portion (112) and includes a contact surface (145) that faces the compartment (150) of the dispenser (100) and is configured to abut the first contact surface (427) of the drive piece (420). The surface (145) of the actuator (124) has a concave shape to match the convex shape of the first contact surface (427). In this view, the drive piece (420) is held in its non-actuated position between the actuator (124) and the elongated and elastic tube chamber (300b) forming the pump (300b) of the second type.

[00140] Figure 9B shows the fluid distribution system (1) as a user has applied a force (P) to the actuator (124) by hand, wherein the user actuator has moved the actuating piece (420) and the actuating head (426) from their non-actuated position towards an actuated position and thus transferred an actuating force (TF) from the actuating piece (420) through the second contact surface (428) to the pump (300b). The pump was compressed laterally towards the rear portion (110) of the dispenser (100) and the surface of the cart (434). This caused the fluid to be dispensed downwards in the direction (Y) of the fluid container (200) from the nozzle (365) thereof. In this view, the actuator (124) rotated counterclockwise around the first pivot (132) to cause the dispenser (100) to be actuated. Petition 870260066011, dated 03 / 07 / 2026, page 52 / 186 43 / 77 Once the user removes their hand from the actuator (124), the actuator rotates clockwise towards the front portion (112) to the position it was in before the user exerted force (P) on it. The drive piece (420) is then returned to its non-actuated position, at which point the pumping chamber is replenished by the supply of a filling force provided by the inherent resilience of the pumping chamber wall (300b) (not shown).

[00141] Figures 10A to 10B show one embodiment of an adapter assembly (400) for use with a fluid container (200) with a pump (300b) of the second type, in particular the fluid container (200) with the elongated elastic tube chamber (300b) as shown in Figure 5.

[00142] The adapter assembly (400) is generally similar to the embodiment shown in Figures 6A to 6C, with only a few differences. A first difference is the shape of the drive piece (420). In this embodiment, the drive piece (420) is substantially L-shaped in its form with an elongated arm extending in a longitudinal direction (L1) between two opposite ends of the arm. A first end (424) is connected to the first connecting support (410) in either of the ways described in relation to the embodiment of Figures 6A to 6C, i.e., it can be connected in an articulated way or fixedly connected to the first connecting support (410). In the case where it is fixedly connected to the first connecting support (410), the arm can be made flexible or elastic to allow movement towards the fixed carriage (430).A second end of the arm carries a drive head (426) comprising a first contact surface (427) for contacting the user actuator (124) and a second contact surface (428) for contacting the pump (300b) of the second type. The drive head (426) is... Petition 870260066011, dated 03 / 07 / 2026, page 53 / 186 44 / 77 projects outward from the second end of the arm in a direction (W) being a direction substantially perpendicular to the longitudinal direction (L1) of the elongated arm to form the actuating head (426) with first and second contact surfaces (427; 428) back to back. The first contact surface (427) is shown here as an elongated flat surface to contact a side flange (147) on the actuator (124) and provide a sliding surface for this flange (147), see Figure 10C. However, the shape may be modified to allow a desired contact with the flange (147) or adopt any shape to properly contact a surface of the actuator (124) in a form-fitting manner, for example, to adopt the shape shown in Figure 6B and allow the first contact surface (427) to contact a surface of the actuator (145) immediately above the flange (147).The second contact surface (428) is in this embodiment also shown as being flat. As discussed above, it may have other suitable shapes for contacting the pump.

[00143] In this embodiment, the first connection support (410) forms a circular sleeve (410) instead of a disc-shaped plate. However, this shape will sit in a form-fitting manner in the same seat in the dispenser (100) as the disc-shaped plate. This shape can provide some extra rigidity to the first connection support (410). It can also provide some additional stabilization for the fluid container (200) supported by the connection support being a fluid container support (470) compared to the disc-shaped plate above. However, the sleeve (410; 470) provides a seat for the fluid container (200) in a manner similar to the disc-shaped element. The sleeve contains an upper part (411) and a lower part (413), the upper part (411) having an outer diameter and an inner diameter that are both larger than the respective dimension of the Petition 870260066011, dated 03 / 07 / 2026, page 54 / 186 45 / 77 lower part (413). In this way, the sleeve forms a downward-facing circular surface (411a) from the upper part (411) and configured to rest on the front and rear shelves (130; 131) of the dispenser (100). In the opening extending axially through the opening (412) of the sleeve, an upward-facing circular edge surface (413a) is provided configured to form a seat for the flange (368) of the connector cover (360) of the fluid container (200) to rest on. Thus, the lower part (413) is configured to be positioned in the retaining opening (139) of the dispenser (100) below the shelf area (130; 131). This can provide some stabilization of the adapter assembly (400) when mounted on the dispenser (100), as well as for the fluid container (200) inserted therein. The glove will also cover the fluid container (200) on its sides.

[00144] In addition, a pin (439) extends rearward from the top (411). This pin (439) acts as a positioning means for engaging the corresponding connector in the form of a positioning opening (137) formed in the rear portion (110) in the locating groove (135) as shown in Figures 8A and 10C. The engagement between the pin (439) and the positioning opening (137) provides correct and simple positioning of the adapter assembly (400) in the dispenser (100) during insertion of the adapter assembly (400) into the fluid dispenser (100). The engagement between the pin (439) and the positioning opening (137) also prevents axial and rotational movement of the adapter assembly (400) and the fluid container support (470) in the dispenser (100) when mounted thereon. The adapter assembly (400) as shown in Figures 10A to 10C has no means of positioning on the fixed carriage (430).However, as for the embodiment shown in Figures 6a to 6c. This embodiment can be used with positioning means arranged in any suitable place, for example, on the fixed carriage (430), to connect the corresponding parts in. Petition 870260066011, dated 03 / 07 / 2026, page 55 / 186 46 / 77 dispenser (100) in a suitable manner.

[00145] In Figures 10A to 10B, the fixed carriage (430) adopts an L-shaped form with a substantially rigid arm with one end fixedly connected to the bottom of the sleeve. The other end of the rigid arm has a carriage portion (432) that extends towards the second contact surface (428) of the drive piece (420) with a concave carriage surface (434) facing the drive piece (420). The concave surface matches in form with the elongated and elastic tube chamber (300b). Furthermore, as shown, the second contact surface (428) of the drive piece (420) may have a width in a horizontal plane that is less than the width of a cavity formed in the surface of the carriage (434) to allow the drive piece (420) to move into the cavity when the drive piece (420) is moved to a driven position.This can provide good compression of the elongated and elastic tube chamber (300b) during fluid dispensing. As mentioned above, the shapes of the different surfaces can be selected depending on the type of fluid container (200) used or the desired dispensing operation.

[00146] A fluid dispensing system assembly (1) including the dispenser (100) of Figure 1, a dispensable container of Figure 5 and the adapter assembly (400) of Figures 10A to 10B resembles the fluid dispensing system assembly (1) including an adapter assembly (400) shown in Figures 6A to 6C. Attention is drawn to the fact that the embodiment shown in Figures 10A and 10B has the positioning means in the form of a pin (439) in a different position from the adapter assembly (400) shown in Figure 6A, for example. As mentioned above, the pin (439) shown in Figures 10A and 10B is configured to engage with the corresponding positioning opening (137), i.e., the connector, Petition 870260066011, dated 03 / 07 / 2026, page 56 / 186 47 / 77 formed in the rear portion (110) in the locating groove (135) as shown in Figures 8A and 10C. Thus, the assembly of the adapter piece can then be very simple by simply inserting the adapter assembly (400) into the retaining opening (139) with the sleeve side (410) carrying the drive piece (420) and the fixed carriage (430) facing down towards the lower end portion (102) of the dispenser (100). The pin (439), as well as the fixed carriage (430), must be positioned towards the rear portion (110) of the dispenser (100) to ensure that the pin (439) is inserted into the corresponding positioning opening (137) in the wall of the rear portion (110) and that the surface of the sleeve (411a) rests correctly on its seats in the dispenser (100), i.e., on the shelves (130; 131).

[00147] The engagement means (140) as shown in Figures 8A and 8C can then be used to hold the sleeve in position within the dispenser (100) as described above to fit and hold the disc-shaped plate. The fluid container (200) is inserted into the dispenser (100) holding the adapter assembly (400) in a manner similar to that described above, wherein an assembled fluid dispensing system (1) will rest on the sleeve as described above.

[00148] As illustrated in Figure 10C and in an assembled fluid distribution system (1), the positions of the drive head (426) as well as the carriage surface (434) are slightly below the corresponding parts of the embodiment shown in Figure 9A. This alters the position for clamping the elongated and elastic tube chamber (300b). The person skilled in the art appreciates that either position can function depending on the position of the elongated and elastic tube chamber (300b) and the properties of the tube chamber (300b). Furthermore, even if the position is suitable for the shape, the drive part (420) has to allow the first surface to be in contact with the rearward-directed side flange (147) of Petition 870260066011, dated 03 / 07 / 2026, page 57 / 186 48 / 77 actuator (124), the person skilled in the art appreciates that the head portion (426) of the drive piece (420) with the second contact surface (428) can be arranged in a position placed further upwards. The position or shape of the fixed carriage (430) can then be adjusted accordingly.

[00149] The operation of the fluid distribution system (1) including the adapter assembly (400) as shown in Figure 10C is largely similar to the operation of the fluid distribution system (1) illustrated in Figures 9A and 9B, except that the drive piece (420) compresses the elongated and elastic tube chamber (300b) in the lower portion thereof and that the tube is compressed in a cavity formed by the carriage surface (434).

[00150] Figures 11A to 11B show one embodiment of an adapter assembly (400) to be used with a fluid container (200) with a pump (300b) of the second type, in particular the fluid container (200) with the elongated elastic tube chamber (300b) as shown in Figure 5.

[00151] This adapter assembly (400) has two separate parts instead of a single-unit adapter assembly (400) as described above. This provides a simple adapter assembly (400) with a minimum of material used. The adapter assembly (400) contains a first part that forms the drive piece (420) with a first connecting portion in the form of a side slot (410) which in a fitted manner can be fixed to a rearward-directed side flange (147) of the actuator (124). The first contact surface (427) of the drive piece (420) near the slot (410) can also form corresponding surface areas of the actuator (124) surrounding the flange when the first part is correctly mounted on the actuator. The overall shape of the drive piece (420) largely corresponds to the drive head (426) shown in Figures 10A and 10B. Petition 870260066011, dated 03 / 07 / 2026, page 58 / 186 49 / 77

[00152] The second part of this embodiment includes a second connection support (460) and also acts as a fluid container support (470) with a fixed trolley (430) attached to it. This second part corresponds to the adapter assembly (400) shown in Figures 10A and 10B with the difference that it does not contain any drive part (420).

[00153] A fluid dispensing system assembly (1) including the dispenser (100) of Figure 1, a dispensable container of Figure 5 and the adapter assembly (400) of Figures 11A to 11B differs from the fluid dispensing system assembly (1) including the embodiment of Figures 10A and 10B in that the first part (420) needs to be removablely attached to the dispensing system by fitting the slot (410) of the first part into a central portion of the flange (147) of the actuator (124). The attachment of the first part (420) can be performed before or after the assembly of the second part (460; 470; 430) on the dispenser (100). The attachment of the second part is performed as described for the adapter assembly (400) of Figures 10A and 10B. The fluid container (200) is inserted into the dispenser (100) with the second part mounted on it.

[00154] As illustrated in Figure 11C and in an assembled fluid distribution system (1), the positions of the drive head (426), as well as the carriage surface (434), are similar to the positions of the corresponding part shown for the embodiment of Figure 10C. The person skilled in the art appreciates that the first part forming the drive piece (420) can be shaped to present the second contact surface (428) in a position placed further upwards. The position or shape of the fixed carriage (430) can then be adjusted accordingly.

[00155] The operation of the fluid distribution system (1) including the adapter assembly (400) as shown in Figure 11C largely resembles the operation of the fluid distribution system (1) illustrated in Petition 870260066011, dated 03 / 07 / 2026, page 59 / 186 50 / 77 Figures 9A and 9B, except that the first part that forms the drive piece (420) becomes part of the actuator (124) and is movable together with the actuator (124), wherein a user force (P) applied to the actuator (124) displaces the drive piece (420) from a non-actuated position to the actuated position, thus compressing the elongated and elastic tube in the lower portion thereof, wherein the tube is compressed into a cavity formed by the carriage surface (434).

[00156] Figures 12A to 12B show one embodiment of an adapter assembly (400) for use with a fluid container (200) with a pump (300b) of the second type, in particular the fluid container (200) with the elongated elastic tube chamber (300b) as shown in Figure 5.

[00157] This adapter assembly (400) is divided into three separate parts instead of forming a two-part adapter assembly (400) or as a single unit. This provides a simple adapter assembly (400) with a minimum of material used. The adapter assembly (400) contains a first part forming a drive piece (420) with a first connecting portion in the form of a side slot (410) which in a fitted manner can be fixed to the rear-facing side flange (147) of the actuator (124). The first contact surface (427) of the drive piece (420) around the slot (410) can also form coincide with the surface areas of the actuator (124) around the flange (147) when the first part is correctly mounted on the drive piece (420). The overall shape of the drive piece (420) corresponds in large with the drive head (426) shown in Figures 10A; 10B; 11A; 11B.

[00158] The second part of this embodiment includes a fixed carriage (430) with a second connecting support (460) in the form of vertical slots (460a; 460b) which can be fitted to the flanges in an adjustable manner. Petition 870260066011, dated 03 / 07 / 2026, page 60 / 186 51 / 77 verticals (141a; 141b) arranged in the rear portion (110) as described above and shown in Figure 8A.

[00159] The third part corresponds to the sleeve shown in Figures 10A and 10B, forming only a fluid container support (470). Thus, this sleeve does not connect to the drive piece (420) and the fixed carriage (430).

[00160] A fluid distribution system assembly (1) including the dispenser (100) of Figure 1, a dispenseable container of Figure 5 and the adapter assembly (400) of Figures 12A to 12B differs from the fluid distribution system assembly (1) including the embodiment of Figures 10A and 10C in that the three parts of the adapter assembly (400) need to be attached to the dispenser (100) separately. The first part forming the actuating piece (420) needs to be removablely attached to the distribution system by fitting the slot (410) of the first part into a central portion of the side flange (147) of the actuator (124). The second part that forms the fixed cart (430) needs to be removablely attached to the rear portion (110) of the dispenser (100) by adjusting the vertical slots (460a; 460b) of the second part to the two vertical flanges (141a; 141b) arranged on the rear portion (110) at a suitable height corresponding to the height of the first part.The attachment of the third part is generally carried out as described for the adapter assembly (400) of Figures 10A and 10B. The attachment of the different parts to the dispenser (100) can occur in any order before inserting the fluid container (200) into the dispenser (100).

[00161] As illustrated in Figure 12C and in an assembled fluid distribution system (1), the positions of the drive head (426) as well as the carriage surface (434) are similar to the positions of the corresponding parts shown for the embodiments of Figures 10C and 11C. Those skilled in the art appreciate that the first part forming the drive piece (420) can be molded to present the second surface. Petition 870260066011, dated 03 / 07 / 2026, page 61 / 186 52 / 77 contact in a position placed higher up. The position or shape of the fixed carriage (430) can then be adjusted accordingly.

[00162] The operation of the fluid distribution system (1) including the adapter assembly (400) as shown in Figure 12C largely resembles the operation of the fluid distribution system (1) shown in Figure 11C and as illustrated in Figures 9A and 9B. Thus, the first part that forms the drive piece (420) becomes part of the actuator (124) and is movable together with the actuator (124), wherein a user force (P) applied to the actuator (124) displaces the drive piece (420) from the non-actuated position to the actuated position, thus compressing the elongated and elastic tube in the lower portion thereof, wherein the tube is compressed into a cavity formed by the carriage surface (434).

[00163] Figure 13A illustrates one embodiment of an adapter assembly (400) comprising a first connection support (410) being an elastic and flexible element with a recess (480) having a lateral dimension larger than the pump has in the lateral direction. As shown in Figure 13A, the elastic and flexible element has a circular shape with a central through opening (480) forming the recess. The drive piece (420) and the fixed carriage (430) are carried by the element and form portions that project from the opposite side within the recess, so that the pump (300b) of the second type can be configured between the second contact surface (428) of the drive piece (420) and the fixed carriage (430).As illustrated in Figure 13B, the elongated and elastic pump chamber (300b) of the fluid container (200) as shown in Figure 5 can be inserted into the passage opening (480) of the ring and placed between the two protruding portions, wherein the elastic ring securely tilts the protruding portions opposite the pump (300b) in a non-compressive and non-distorted manner, i.e., in a non-actuated position. Those skilled in the art understand that... Petition 870260066011, dated 03 / 07 / 2026, page 62 / 186 53 / 77 dimensions, shapes and materials can be adjusted to provide the proper tilt of the structure in the non-driven position.

[00164] Figure 13C shows a partial cross-sectional view of one embodiment of a fluid distribution system (1) viewed from the side. The fluid distribution system (1) comprises the fluid container (200) and the adapter assembly (400), as shown in Figure 13B.

[00165] The flexible and elastic element forms the first connecting support (410) to hold the fixed carriage (430) and the actuating part (420) in the form of the two portions that project into the passage opening (480) of the flexible and elastic element, shown here as a spring ring. The spring ring with the projecting portions can also form a fluid container support (470). It provides a connection to the fluid container (200) and is configured to rest on the front and rear portions (110; 112) of the dispenser (100) on a lower end portion (102) of the dispenser (100). Thus, the diameter of the spring ring has a dimension to just fit into the seat between the rear portion (110) and the actuator (124). Optionally, the adapter assembly (400) may additionally, or as an alternative, comprise the fluid connection support (470) of the embodiment shown in Figures 12A and 12B, or similar.

[00166] A fluid dispensing system (1) set shown in Figure 13C including the dispenser (100) of Figure 1, a dispensable container of Figure 5 and the adapter set (400) of Figures 13A to 13B is simple and involves only a few steps. After opening the front cover of the dispenser (100), the fluid container (200) is inserted into the dispenser (100) from the top with the elongated and elastic pump chamber inserted through the retaining opening (139) of the dispenser (100). The elastic and flexible element is then brought from the bottom of the dispenser (100) into the elongated and elastic tube chamber (300b) of the fluid container (200) inserted into the dispenser. Petition 870260066011, dated 03 / 07 / 2026, page 63 / 186 54 / 77 (100) so that the tube chamber (300b) is placed between the protruding portions of the elastic ring, one of which must be configured close to the rear portion (110) and the other close to the front portion (112) and its actuator (124), see Figure 13C. The height can be adjusted to provide adequate fluid connection support (470) and dispensing.

[00167] The operation of the fluid distribution system (1), including the adapter assembly (400), as shown in Figure 13C, generally resembles the operation of the fluid distribution system (1) illustrated in Figures 9A and 9B. When a user force (P) is applied to the user actuator (124), the elastic ring is compressed from a non-actuated position to an actuated position, i.e., it is compressed towards the carriage (430) and the rear portion (110) of the dispenser (100) so that the elongated elastic pump chamber (300b) is laterally compressed between the second contact surface (428) and the fixed carriage (430) causing the fluid to be dispensed from the fluid container (200).The person skilled in the art understands that the dimensions, shapes and materials can be adjusted to provide the proper inclination of the structure in the non-actuated position and to provide the possibility for a user to press the actuator (124) with their hand to activate the fluid dispensing and return the snap ring to the non-actuated position when the user removes their hand from the actuator (124). The adapter assembly (400) can therefore be made of a plastic material, such as olefin plastic, for example, polyethylene or polypropylene.

[00168] Figures 14A to 14B show one embodiment of an adapter assembly (400) to be used with a fluid container (200) with a pump (300b) of the second type, in particular the fluid container (200) with the elongated elastic tube chamber (300b) as shown in Figure 5.

[00169] The adapter set (400), as shown in Petition 870260066011, dated 03 / 07 / 2026, page 64 / 186 55 / 77 Figures 14A and 14B have functional and structural parts similar to the embodiments shown in Figures 6A to 6C, as well as in Figures 10A and 10B, with some differences that will be explored in more detail below.

[00170] By forming an adapter assembly (400) having the forms of a drive piece (420), a fixed carriage (430) and a first connection support (410) as shown in Figures 14A and 14B, an adapter assembly (400) is provided which is simple to mount safely on the dispenser (100) and which allows easy and reliable insertion and use of the fluid container (200) with the pump (300b) of the second type.

[00171] In this embodiment, the actuator assembly comprises the first connection support (410) of the present invention for removablely connecting the actuator assembly (400) to the fluid distribution system (1). As shown in Figures 14A and 14B, the first connection support (410) comprises an upper part (411) forming a disc-shaped plate portion (411) and a lower part (413) forming the sleeve portion (413) extending downward from the plate portion (411). The sleeve portion (413) is formed with an outer diameter smaller than the plate portion (411). An axial opening extending through the opening (412) extends through the main plane of the plate portion (411) and through the sleeve portion (413).The plate portion (411) has an external shape and dimensions to allow it to rest on a dispenser seat (100) formed by the shelves (130 and 131) of the dispenser (100), as well as being partially engaged with the locating groove (135) on the rear shelf (131) in the rear portion (110) of the dispenser (100) as described herein in relation to Figures 3 and 16A-16C.

[00172] As will be explored in Figures 16A-16C and related description below, a first pin (439) extends backward and upward from the plate portion (411). This pin forms a position half (439) for Petition 870260066011, dated 03 / 07 / 2026, page 65 / 186 56 / 77 engage the corresponding locating groove (135) and the positioning opening (137) formed in the rear portion (110) in the locating groove (135).

[00173] As illustrated in this embodiment, the plate portion (411) can be thinner than the plate shown in Figures 6A-6C. Thus, the pin (439) has the shape and dimensions to engage the locating slot (135) and the positioning opening (137). The shape and dimensions also allow for a thin and flexible plate portion (411), which in turn allows for a snap-fit ​​feature for engaging the first pin (439) with the locating slot (135) and the positioning opening (137) when the adapter assembly (400) is mounted on the dispenser (100). The first connection support (410) or just the plate portion (411) can be made of a flexible and elastic material such as olefin plastics, for example, polyethylene or polypropylene. The use of such material allows for the snap-fit ​​functionality.

[00174] As also illustrated, a protrusion forming a rib portion (446) extends upward from a front portion of an upper surface (435) of the plate portion (411) in front of it and along a portion of the outer periphery of the plate portion (411). The rib portion (446) provides a positioning means to prevent mispositioning of the adapter assembly (400) during insertion into the dispenser (100). This will be explored in more detail later when the fluid dispensing system assembly (1) is described.

[00175] In addition, engagement protrusions (447a; 447b) extend upwards from the upper surface (435) of the plate portion (422) near each end of the rib portion. These engagement portions are shaped and sized to engage the engagement means (140) to hold the disc-shaped plate (411) in place in the dispenser (100), when the Petition 870260066011, dated 03 / 07 / 2026, page 66 / 186 The 57 / 77 adapter assembly (400) is mounted on the dispenser (100). This will be described in more detail in relation to Figures 18A and 18C.

[00176] The lower part (413) is configured to be positioned within the retaining opening (139) of the dispenser below the shelf area (130; 131). This can provide some stabilization of the adapter assembly (400) when mounted on the dispenser (100), as well as for the fluid container (200) inserted therein. In addition, four stabilizers (448a-d) are provided to prevent lateral movement and / or tilting of the adapter assembly during use. The stabilizers (448a-d) are flat, web-shaped portions extending downward from the plate portion (411) and outward from the sleeve portion (413), wherein two (448c; 448d) are located near the rear portion and two (448a, 448b) are located near the front. As shown in Figure 17, the stabilizers (448a-d) are intended to rest on the vertical inner surfaces (160a; 160b) in the dispenser retaining opening just below the shelves (130, 131).

[00177] The first illustrated connection support (410) also forms a fluid container support (470) configured to be received in the compartment (150) of the dispenser (100) to hold the fluid container (200) in a desired position in the compartment (150) of the dispenser (100). This is provided by means of the central passage opening (412) having circular shapes that correspond to the dimensions and shape of the connector cap (360) as shown in Figure 5. The fluid container support (470) has a seat for the connector cap (360) to rest on. In the passage opening (412) which extends axially, an upward-facing circular edge surface (413a) is provided, formed by the sleeve portion (413). This surface (413a) is configured to form a seat for the flange (368) of the connector cap (360) of the fluid container (200) to rest on it.

[00178] As also illustrated, the plate portion (411) of the first Petition 870260066011, dated 03 / 07 / 2026, page 67 / 186 58 / 77 connection support (410) and fluid container support (470) comprises a second pin (472) extending forward of the first pin (439) towards the central passage opening (412). Between the second pin (472) and the circular edge surface (413a), a positioning groove (474) is formed to engage a connection portion of the fluid container (200) being the flange (368) of the connector cover (360) and thus providing a means of positioning the fluid container to prevent axial and / or rotational movement of the fluid container (200) in the dispenser (100) when the fluid container is mounted in the dispenser (100).

[00179] As shown in Figures 14A and 14B, the drive piece (420) has an elongated arm (422) that extends in a substantially longitudinal direction (L1) between two opposite ends of the arm. A first end (424) of the arm is fixedly connected to the plate portion (411) of the first connecting support (410), wherein the arm (422) is made flexible and elastic to allow movement towards the fixed carriage (430). The person skilled in the art realizes that the arm (422) can be movably connected to the first connecting support (410) by other means, as described in relation to the embodiment in Figures 6A to 6C, for example, it can be articulated to the first connecting support (410).A second end of the arm (422) carries a drive head (426) comprising a first contact surface (427) for contacting the user actuator (124) and a second contact surface (428) for contacting the pump (300b) of the second type. Similar to the embodiment of Figures 10A and 10B, the drive head (426) projects outward from the arm (422) near its second end in a direction (W) being a direction substantially perpendicular to the longitudinal direction (L1) of the elongated arm to form the drive head (426) with the first and second contact surfaces (427; 428) facing back to back. Petition 870260066011, dated 03 / 07 / 2026, page 68 / 186 59 / 77 to the other. The drive head (426) is supported by a flat mesh portion (440) with a first flange portion (441) at the front formed by the arm and a second flange portion (442) extending at an oblique angle downwards and backwards from the elongated arm (422) to a third flange portion (443) extending downwards and parallel to the flange portion (441) of the arm (422). The illustrated drive head (426) is adopting a flat shape with a second longitudinally extended contact surface (428) formed by the third flange portion (443).

[00180] The first contact surface (427) is shown here as formed by the extended portion of the arm (422) forming the first flange portion (441) of the actuating head (426). The first contact surface (427) is an elongated flat surface to contact the side flange (147) on the actuator (124) and provide a sliding surface for this flange (147), see Figure 18A. The side width of the first contact surface (427), as shown in Figure 14B, is narrow compared to the first contact surface (427) shown, for example, in Figures 10A and 10B. This may allow for a better fit of this embodiment of the adapter assembly (400) within the compartment (150) of the dispenser (100) without any risk of incorrectly touching any unwanted portions within the dispenser (100) when the adapter assembly is used in the dispenser.

[00181] A person skilled in the art understands that the shape of the drive head (426) can be modified to allow a desired contact with the flange (147) or to adopt any shape to properly contact a surface of the actuator (124) in a form-fitting manner, for example, to adopt any other shape shown herein, such as the shape shown in Figure 6B, and allows the first contact surface (427) to be in contact with a surface of the actuator (145) just above the flange. Petition 870260066011, dated 03 / 07 / 2026, page 69 / 186 60 / 77 (147).

[00182] The second contact surface (428) comprises a substantially flat and longitudinally elongated (L1) surface formed by the third flange portion (443) and an outwardly rounded upper surface portion (444) located adjacent to the second flange portion (443). Thus, a second contact surface (428) is provided that is adapted to contact the elongated and elastic tube chamber (300b) over a longer vertical distance than the adapter assemblies (400) shown previously. This will be explored in more detail below in relation to Figures 18A-18C. As discussed above in relation to other embodiments, the second contact surface (428) may adopt other forms suitable for contacting the pump (300b), such as adopting a concave or convex surface.

[00183] In Figures 14A and 14B, the fixed carriage (430) extends downwards from the sleeve portion (413) of the first connecting portion (410). The fixed carriage (430) comprises a recessed carriage surface (434) being concave in shape and facing the drive piece (410). A cavity is provided by the recessed carriage surface (434) to house the pump (300b) which has a shape and dimension suitable to fit into the cavity. An upper portion (434a) of the fixed carriage (430) forms a recessed carriage surface portion (434a) being concave and in the shape of a hollow half of a cone that tapers in a direction from the upper end to the lower end of the adapter assembly (400). The lower portion (434b) of the fixed carriage (430) forms a recessed carriage surface portion (434b) being concave and forming a hollow semicylinder.This concave surface portion (434b) adopting the shape of a hollow semicylinder combines in form with the elongated and elastic tube chamber (300b) as shown in Figure 5. By forming the upper portion (434a) with the shape of half a. Petition 870260066011, dated 03 / 07 / 2026, page 70 / 186 61 / 77 cone, an easy and smooth insertion of the fluid container (200) into a dispenser (100) carrying the adapter assembly (400) is provided. As will be explored further, the tapered surface portion (434a) guides the insertion of the fluid container (200) into its intended position in the dispenser (100).

[00184] The second contact surface (428) of the drive head (426) has an upper contact surface portion (428a) that faces the upper portion (434a) of the recess, being in the shape of the hollow half of a cone, when the second contact surface portion has been moved to its position closest to the fixed carriage. The second contact surface has a lower contact surface portion (428b) facing the lower end portion (434b) of the recess, being in the shape of the hollow semi-cylinder, when the lower contact surface portion has been moved to its position closest to the fixed carriage.This may allow displacement of the pump (300b) into the cavity during the distribution drive, so that the pump (300b) is compressed and distorted in a different manner along the length of the pump for proper and reliable fluid distribution, i.e., the pump (300b) in the form of the elongated and elastic tube chamber will be displaced by the drive piece (420) so that an upper portion of the pump (300b) is compressed into the upper portion (434a) of the recess being in the form of the hollow half of a cone and the lower end portion of the pump (300b) will be compressed into the lower end portion (434b) of the recess being in the form of the hollow semicylinder, see Figure 18B.

[00185] Furthermore, as is evident, the second contact surface (428) of the drive piece (420) has a width in a horizontal plane that allows the drive piece (420) to move into the cavity formed by the recessed carriage surface (434). This Petition 870260066011, dated 03 / 07 / 2026, page 71 / 186 62 / 77 provides good compression of the elongated and elastic tube chamber portion (300b) during fluid dispensing. As mentioned above, the shapes of the different surfaces can be selected depending on the type of fluid container (200) used or the desired dispensing operation.

[00186] The drive piece (400) has an elastic and flexible arm (422) formed in a rest (equilibrium) position so that a portion of the drive head (426) is received within the recessed surface portion (434) before being used in the dispenser (100) and without a pump (300b) placed between the drive head (426) and the fixed carriage (430). When a pump (300b) is inserted between the fixed carriage (430) and the drive head (426), the elastic and flexible arm (422) is moved forward from its rest (equilibrium) position towards the non-actuated position, in which the drive head (426) touches the pump (300b) exerting a spring force on it in a pre-tensioned manner. Thus, the adapter assembly (400) is configured so that at least a portion of the second contact surface (427) touches the pump in the non-actuated position.

[00187] The fixed carriage (430) comprises a rearward projecting flange (437) extending from and along the rear surface (438) of the fixed carriage. This flange (437) is configured to support a side edge (114) on the underside of the rear portion (110) of the dispenser (100) so as to support and prevent any movement of the fixed carriage during dispenser operation, see Figures 18A and 18B.

[00188] The materials suitable for forming the actuator assembly (400) may be aluminum or any suitable plastics, such as olefin plastics, for example, polyethylene or polypropylene. The adapter assembly may be formed by injection molding, 3D printing or any other suitable method known to those skilled in the art. The materials mentioned and the formation of the adapter assembly (400) may be used for all Petition 870260066011, dated 03 / 07 / 2026, page 72 / 186 63 / 77 ways of implementation described here.

[00189] In addition, the described adapter assembly (400) may have the following example dimensions. The circular plate portion (411) may have an outer diameter of about 51 mm and the diameter of the passage opening (412) in the plate portion may be about 34 mm. The diameter of the passage opening (412) of the sleeve portion (413) may be about 31 mm. The thickness of the plate portion (411) may be about 2.5 mm. The sleeve portion (413) may extend from the plate with a length of about 6 mm, the drive piece (420) may extend from the plate portion (411) with a length of 54 mm and the fixed carriage (430) may extend from the sleeve portion (413) with a length of about 47 mm. The second contact surface (428) has a width of about 4 to 6 mm and a height of about 22 mm. The dimension between the first contact surface (427) and the second contact surface can be about 21 mm.The upper portion (434a) of the fixed carriage (430) forming the hollow half of a cone may have a maximum width of 31 mm and the lower end portion (434b) of the fixed carriage (430) forming the hollow semicylinder may have a width of about 13 mm and a length of about 27 mm. The diameter length of the elongated and elastic tube chamber (300b) may be 14 mm and the cap length about 56 mm.

[00190] A fluid dispensing system assembly (1) including the dispenser (100) of Figure 1, a disposable container of Figure 5 and the adapter assembly (400) of Figures 14A and 14B resembles the fluid dispensing system assembly (1) including an adapter assembly (400) shown in Figures 6A to 6C. Figure 15 schematically illustrates a fluid dispensing system assembly (1) including the adapter assembly (400) of Figures 14A and 14B.

[00191] After opening the front cover (113), the assembly of Petition 870260066011, dated 03 / 07 / 2026, page 73 / 186 The 64 / 77 adapter (400) is mounted on the dispenser (100) by inserting it through a retaining opening (139) to hold the fluid container (200) in the lower end portion (102) of the dispenser (100). This is best shown in Figures 16A-16C, showing enlarged views of the lower portion of the interior inside the dispenser (100) with and without the adapter assembly (400) inserted into the dispenser (100) viewed from an angle above towards the rear portion (110) of the lower end portion (102). As shown in Figure 16A, the retaining opening (139) is circular in shape and the rear shelf (131), the locating groove (135) formed between the rear shelf (131) and the pin (136) are arranged in the rear portion (110) as described above in relation to Figures 4A and 8A.

[00192] As shown in Figure 16A, the locating groove (135) extends rearward through the opening (137) formed in the wall of the rear portion (110) to form the positioning opening (137). The purpose of this positioning opening (137) has been described above and will be explained in more detail below.

[00193] The adapter assembly (400) is inserted into the retaining opening (139) with the side of the first connecting support (410) carrying the drive piece (420) and the fixed carriage (430) facing down towards the lower end portion (102) of the dispenser (100) and with the fixed carriage (430) being positioned towards the rear portion (110) of the dispenser (100). When the adapter is fully inserted, the first connecting support (410) and the plate portion (411) rest on the front and rear shelves (130; 131) and the first pin (439) engages in the locating groove (135) between the rear shelf (131) and the pin (136), see Figure 16B including its enlarged portion. In addition, the first pin (439) also engages with the positioning opening (137) on the rear portion (110) of the dispenser (100). This engagement provides correct positioning of the assembly. Petition 870260066011, dated 03 / 07 / 2026, page 74 / 186 65 / 77 of adapter (400) in the dispenser (100) during insertion of the adapter assembly (400) into the fluid dispenser (100). The engagement between the first pin (439) and the positioning opening (137) also prevents axial and rotational movement of the adapter assembly (400) in the dispenser (100).

[00194] Insertion of the adapter assembly (400) is facilitated by a quick-fit arrangement between the first pin (439) and the connector parts with which it engages during insertion and when the adapter assembly is mounted on the dispenser, for example, the pin parts (136), the locating groove (135) and the positioning opening (137) on the rear portion (110) of the dispenser (100). This is made possible by the shapes of the connector parts, such as the pins (136 and 439), and by the provision of elastic and flexible parts, such as a flexible and elastic plate portion (411), a first elastic and flexible pin (439), an elastic and flexible pin (136) and an elastic and flexible rear portion part (110) near the pin (136). One or more of these parts may be of a flexible and elastic material such as olefin plastics, for example, polyethylene or polypropylene. The use of such material allows for the fitting functionality.

[00195] As mentioned above, the protrusion that forms the rib portion (446) extending upwards from a portion of the upper surface (435) of the plate portion (411) in front thereof provides a positioning means to prevent incorrect rotational positioning of the adapter assembly (400) during insertion into the dispenser (100). The person skilled in the art appreciates that the portion with the protrusion has a vertical dimension / thickness that does not allow this portion to be placed in the direction of the rear portion (110) for engagement with the locating groove (135) between the rear shelf (131) and the pin (136).

[00196] As illustrated in Figures 16A and 17, the four stabilizers (448a-d) in the adapter assembly guide the assembly of Petition 870260066011, dated 03 / 07 / 2026, p. 75 / 186 66 / 77 adapter (400) for the correct position in the dispenser when contacting the vertical inner surfaces (160a; 160b) in the retaining opening (139) of the dispenser just below the shelves (130, 131) during insertion. When the adapter is fully inserted, the stabilizers (448a-d) rest on the vertical inner surfaces (160a; 160b), where lateral and / or tilting movements of the adapter assembly are prevented during dispenser operation.

[00197] As also shown in Figures 16A-16C, the dispenser (100) includes the engagement means (140) for holding the first connection support (410) and the disc-shaped plate portion thereof (411) in the dispenser (100). As the first connection support (410) also forms the support for the fluid container (470) in this embodiment, the provision of the engagement means (140) also provides means for holding the fluid container support (470) in place when inserting the fluid container (200) into the dispenser (100), using the dispenser (100) and removing the fluid container (200) from the dispenser (100).

[00198] The engagement means (140) have been described above in relation to Figures 8A-8C. Thus, the engagement means (140) in the form of the C-shaped element is movable in a horizontal plane from the non-retaining position, as shown in Figure 16B, in the rear direction to the retaining position, as shown in Figure 16C. In the retaining position, the engagement means (140) has portions (140a, 140b) that engage with the disc-shaped plate portion and with the upward-projecting portions (447a; 447b) in front of the plate. A person skilled in the art understands that the plate can also be adapted in other ways to engage with the engagement means (140), as described in this document. In the embodiment shown, the engagement means is held in its retention position by the housing by the engagement means (140) being resiliently suspended in the dispenser (100) so that when the Petition 870260066011, dated 03 / 07 / 2026, page 76 / 186 67 / 77 when the housing (116) is open, the engagement means (140) is held in an open position by, for example, a spring. An adapter assembly can be removed from the dispenser (100) and a new adapter assembly (400) can be placed in the dispenser (100). When the housing (116) is being closed, the engagement means (140) is pushed by the housing (116) against the spring into an engaged and retaining position, in which the adapter assembly is engaged. Thus, the engagement means (140) does not need to be locked in the retaining position by a frictional interaction with the plate.

[00199] As best seen in Figures 18A and 18B, the rearward protruding flange (437) extending from and along the rear surface (438) of the fixed carriage of the adapter assembly (400) that has been inserted into the dispenser rests on the side edge (114) at the bottom of the rear portion (110) of the dispenser (100) so as to support and prevent any movement of the fixed carriage during the operation of the dispenser (100).

[00200] As schematically illustrated in Figure 15, the next step in assembling the fluid distribution system (1) is to insert the fluid container (200) into the dispenser (100) now holding the adapter assembly (400). The fluid container (200) is inserted with its pump from an elongated and elastic tube chamber (300b) into the central passage opening (412) of the fluid container holder (470) until the connector cap (360) of the fluid container (200) with its flange (368) rests on the seat formed by the adapter assembly (400) in the dispenser (100) as described above and also provided from Figure 18A.As described above, the plate portion (411) of the first connecting support (410) that forms the support for the fluid container (470) is provided with means for positioning the fluid container to prevent axial and / or rotational movement of the fluid container (200) in the dispenser (100), when the fluid container is mounted in the dispenser (100). The means for positioning the fluid container is formed. Petition 870260066011, dated 03 / 07 / 2026, page 77 / 186 68 / 77 by the positioning groove (474) located between the second pin (472) and the circular edge surface (413a) of the fluid container holder (470). This positioning groove (474) is configured to engage the flange (368) of the connector cap (360) which is forming a connecting portion for the positioning groove (474). As a fluid container (200) is inserted into its position in the dispenser and adapter assembly, a quick-fit arrangement between the flange (368) of the connector cap (360) and the second pin (472) allows the flange (368) to engage the positioning groove (474) and rest on the circular edge surface (413a) of the fluid container holder (470) (not shown). The quick-fit arrangement is made possible by the shapes of the connecting parts, such as the second pin (472), which has a rounded surface portion facing upwards, and by the supply of elastic and flexible parts.Thus, any parts that form the interlocking components or parts close to the components can be made of a flexible and elastic material, such as olefin plastics, for example, polyethylene or polypropylene. The use of such material allows for the interlocking functionality.

[00201] Figure 18A also illustrates that the fluid container (200) is inserted so that the elongated and elastic tube chamber is placed between the second contact surface (428) of the drive piece (420) and the carriage surface (434) of the fixed carriage (430). The insertion of the elongated and elastic tube chamber (300b) in this position is supported by the recessed surface portion (434a) taking the form of half a cone, wherein the tapered surface portion guides the tube chamber (300b) of the fluid container (200) into its position which it should have in the dispenser (100), that is, to be located between the drive piece (420) and the fixed carriage (430). In the inserted position, the elongated and elastic tube chamber (300b) is partially received within the cavity formed by the recessed carriage surface (434) being concave in shape, i.e., the surface having the carriage surface portion Petition 870260066011, dated 03 / 07 / 2026, page 78 / 186 69 / 77 upper recessed (434a) being in the form of a hollow half of a cone and the lower recessed carriage surface portion (434b) being concave and forming a hollow semicylinder, see Figures 16A-16C and 18A. As shown in Figure 18A, the concave surface portion (434b) adopting the form of a hollow semicylinder matches in form with the elongated and elastic tube chamber (300b).

[00202] The assembly of the fluid distribution system (1) is then completed by closing the dispenser (100) by moving the upper portion of the front cover to the rear portion (110) and, optionally, locking the cover onto the rear portion. The dispenser (100) is then ready for use.

[00203] Figures 18A and 18B show a perspective view of a lower end portion (102) of the fluid dispensing system (1) of Figure 15, when mounted in a fluid dispensing system (1) as shown in Figure 1, with a portion of the dispenser (100) cut away to show details of the interior of the fluid dispensing system (1) in operation.

[00204] According to Figure 18A, the fluid container (200) rests on its seat in the dispenser (100) which is formed by the first connection support (410) forming the support of the fluid container (470) of the adapter assembly (400) shown in Figures 16A and 16B being mounted in a removable manner in the dispenser (100). The fluid pump (300b) of the second type being an elongated and elastic tube chamber (300b) that extends downwards from the fluid container (200) and between the second contact surface (428) of the drive piece (420) and the surface of the carriage (434) of the fixed carriage (430) to the nozzle (365) at the bottom of the dispenser (100). The nozzle (365) is placed in the lower part of the dispenser (100) so as to avoid the risk of contaminating any part of the dispenser when dispensing any fluids from the fluid container (200), but at the same time it is not clearly visible to a user when using the dispenser (100). The position of the nozzle (365) Petition 870260066011, dated 03 / 07 / 2026, p. 79 / 186 70 / 77 depends, for example, on the dimensions of the fluid container (200) and the position that the fluid container (200) may have in the dispenser (100). The person skilled in the art will appreciate how to adapt the fluid container support (470) or its position so as to adjust the position of the nozzle (365). The adapter assembly (400) can also be modified to adjust its position relative to the pump, as well as the shape of the pump and the maximum volume desired to be dispensed from the fluid container (200). Some examples of dimensions and shapes of the adapter assembly (400) were presented above for the embodiment now shown in Figure 18A. These dimensions and shapes can be provided for other embodiments shown in this document.For example, the dimensions of the drive head (426) and the fixed carriage (430) are adjusted so that a pump placed between them in the dispenser (100) and in the non-driven position can be in a desired shape in order to provide a reliable and sufficient dispensing operation when driven.

[00205] In Figure 18A, the actuator (124) is rotated on the first pivot (132) to the front portion (112) and includes the rearward-directed side flange (147) of the actuator (124) having an edge that is facing the compartment (150) of the dispenser (100) and is configured to abut the first contact surface (427) of the drive piece (420). In this view, the drive piece (420) is held in its non-actuated position between the actuator (124) and the elongated and elastic tube chamber (300b) forming the pump (300b) of the second type. As illustrated, the drive piece (422) and its extended arm (422) are moved forward from their rest (equilibrium) position towards the non-driven position, in which the drive head (426) touches the pump (300b) exerting a spring force on it in a pre-tensioned manner. The outwardly rounded upper surface portion (444) and the upper contact surface portion (428a) of the second Petition 870260066011, dated 03 / 07 / 2026, page 80 / 186 71 / 77 contact surfaces abut and slightly deform the elongated and elastic tube chamber (300b) in a pre-tensioned manner. The central portion and the lower portion (428b) of the second contact surface (428) extend in a forward and downward direction in the non-actuated position.

[00206] Figure 18B shows the fluid distribution system (1) as a user has applied a force (P) with their hand to the actuator (124), wherein the user actuator has moved the actuating piece (420) and the actuating head (426) from their non-actuated position towards an actuated position, and has thus transferred an actuating force (TF) from the actuating piece (420) through the second contact surface (428) to the pump (300b). The pump was compressed laterally towards the rear portion (110) of the dispenser (100) and the surface of the cart (434). This caused the fluid to be dispensed downwards in the direction (Y) of the fluid container (200) and the nozzle (365) thereof. In this view, the actuator (124) rotated counterclockwise around the first pivot (132) to cause the dispenser (100) to be actuated.During the displacement of the drive head (426) towards the driven position, the contact between the second contact surface (428) and the pump (300b) gradually increases from the non-driven position to the fully driven position. The contact gradually increases downwards from the upper end portion (428a) of the second contact surface (428) to the lower end portion (428b) of the second contact surface (428). This allows for reliable dispensing operation, where the fluid is dispensed in a controlled manner with a low risk of fluid backflow within the pump (300b), as the upper end portion (428a) of the second contact surface (428) first contacts the pump (300b) allowing the elongated and elastic tube chamber (300b) to close off any fluid backflow.

[00207] Once the user removes their hand from the actuator (124), the Petition 870260066011, dated 03 / 07 / 2026, page 81 / 186 72 / 77 actuator rotates clockwise towards the front portion (112) to the position it had before the user exerted force (P) on it. The drive piece (420) is then returned to its non-actuated position as shown in Figure 18A, when replenishment of the pumping chamber occurs by supplying a filling force provided by the inherent resilience of the pumping chamber wall (not shown).

[00208] Figures 18 to 22 show embodiments of the adapter assembly (400) according to the invention to be used with a fluid container (200) with a pump (300b) of the second type, in particular the fluid container (200) with the elongated elastic tube chamber (300b) as shown in Figure 5.

[00209] The embodiments of the adapter assembly (400) shown in these Figures are variants of the embodiment shown in Figures 14A and 14B, with only a few differences.

[00210] As illustrated in Figures 19 to 22, the disc-shaped plate portion (411) may adopt other forms besides the form first described above in relation to the embodiment of Figures 14A and 14B. As shown in Figures 19 to 21, the plate portion (411) may, in part, adopt a circular form with two straight edges (415a; 415b) connecting convex front and rear portions of the plate portion (411). This form also allows the plate portion (411) to rest on the front and rear shelves (130; 131) in the dispenser (100).Those skilled in the art will understand that, although this form, as well as the circular disc form of the plate portion (411) with the central passage opening (412), are examples for use in a first connection support (410) as well as in a fluid container support (470) in the context of the present invention, other types of first connection supports (410) and fluid container supports (470) may also be used in the context of the illustrated variants of the adapter assembly (400) herein. Petition 870260066011, dated 03 / 07 / 2026, page 82 / 186 73 / 77 described. These types include first connection supports (410) of forms other than the disc-shaped plate portion (411) with the central passage opening (412), including, but not limited to, a plate or sleeve portion having in part a circular shape with more than two straight edges or an external polygonal shape, such as a hexagonal or octagonal shape, still having portions supported on the shelf seats (130 and 131) of the dispenser (100). The person skilled in the art also appreciates that the circular passage opening (412) may adopt other forms, including, but not limited to, a polygonal shape which may still form the seat for the fluid container (200) and the connector cover (360) or similar.

[00211] As illustrated in Figures 19 to 21, the protruding pin (439) can be formed in a different manner. As shown in Figure 19, the pin (439) is part of an elongated elastic and flexible element that extends upwards and backwards from the sleeve portion (413) of the first connecting support (410) through an opening (471) formed in the rear portion of the first connecting support (410) to a position in the rear portion of the plate portion (411). The flexible and elastic element allows quick engagement with the pin (136), the locating groove (135) between the rear shelf (131) and the pin (136) in the rear portion (110) of the dispenser (100) and the positioning opening (137) formed in the rear portion (110) in the locating groove (135).

[00212] In Figures 20 and 21, the pin (439) extends backward and upward from a rear edge of the plate portion (411) to engage in the corresponding locating groove (135) and the positioning opening (137) formed in the rear portion (110) in the locating groove (135). An opening (119) is formed in the rear portion of the plate portion (411). This opening (119) is formed to provide a flexible portion between the opening (119) and the pin (439) so as to allow engagement by snapping. Petition 870260066011, dated 03 / 07 / 2026, page 83 / 186 74 / 77 quick between the pin (439) and the locating groove (135) between the rear shelf (131) and the pin (136) in the rear portion (110) of the dispenser (100) and the positioning opening (137) formed in the rear portion (110) in the locating groove (135).

[00213] As also illustrated in Figures 19 to 22, the engagement protrusions (447a; 447b) extending upward from the upper surface (435) of the plate portion (422) near each end of the rib portion (446) may be formed differently from that shown for the embodiment of Figures 14A and 14B. The engagement protrusions shown (447a; 447b) are all shaped and dimensioned to engage the engagement means (140) to hold the disc-shaped plate (411) in place in the dispenser (100), when the adapter assembly (400) is mounted in the dispenser (100), see Figures 18A and 18C.

[00214] As shown in Figures 19 to 22, the drive parts (420) are also slightly different from those shown in Figures 14A and 14B. In Figures 19 and 20, the drive part (420) has the elongated arm (422) extending longitudinally and fixedly connected to the plate portion (411) of the first connecting support (410), wherein the arm (422) is made flexible and elastic to allow movement towards the fixed carriage (430). The person skilled in the art appreciates that the arm (422) can be movably connected to the first connecting support as described in relation to the embodiment of Figures 6A to 6C. Similar to the embodiment of Figures 14A and 14B, the drive head (426) has first and second contact surfaces (427a-b; 428) facing back to back.The drive head (426) is supported by two flat mesh portions (440a, 440b) that extend between the first contact surfaces (427a; 427b) formed by two edges of the mesh portions (440a, 440b) and the second contact surface (428) formed by a portion connecting them. Petition 870260066011, dated 03 / 07 / 2026, page 84 / 186 75 / 77 plot portions (440a, 440b).

[00215] Regarding the embodiment shown in Figures 14A and 14B, the first contact surfaces (427a; 427b) are configured to contact the side flange (147) on the actuator (124) of the dispenser (100) and provide sliding surfaces for this flange portion (147) during the operation of the dispenser (100). The illustrated drive head (426) is wider than that shown in Figures 14A and 14B with the first two contact surfaces (427a; 427b) instead of one, so as to provide an alternative for good and reliable operation during fluid dispensing. As shown, the second contact surface is also wider than that shown in Figures 14A and 14B.However, the person skilled in the art appreciates that the dimension of the second contact surface (428), as well as other parts of the adapter assembly (400), can be adjusted to fit, for example, the dispenser (100) and the pump (300b) with which it will be used, as well as the desired dispensing operation for the fluid to be dispensed.

[00216] The drive parts (420) shown in Figures 21 and 22 are very similar to those shown in Figures 14A and 14B, except that the drive head (426) shown does not have the first flange portion (441) on its front. Thus, the first contact surface (427) is formed by an edge on the front of the flat mesh portion (440). This edge (427) is also configured to contact the side flange (147) on the actuator (124) of the dispenser (100) and to provide a sliding surface for this flange (147) during the operation of the dispenser (100). Thus, the drive head (426) has a narrow, flat shape that can be easily received into the compartment (150) of the dispenser (100) and that can provide proper dispensing operation. The width of the flat mesh portion (440) and its edge (427) can be adjusted to provide a suitable contact surface for the side flange (147). Petition 870260066011, dated 03 / 07 / 2026, page 85 / 186 76 / 77

[00217] Figure 23 shows an embodiment also being a variant of the embodiments described above in relation to Figures 14A-14B and 18 to 22. This embodiment has a first connecting support (410) with a plate portion (411) which partly adopts a circular shape with two straight edges (415a; 415b) connecting the convex front and rear portions of the plate portion (411). The plate portion (411) is made flat and the pin (136) extends from a rear edge of the plate portion. This first connecting support (410) has many functional and structural similarities with the circular sleeve shown in Figures 10A and 10B.

[00218] The adapter assembly has a similar drive piece (420) as have the embodiments shown in Figures 21 and 22.

[00219] As shown in Figure 23, the fixed carriage (430) is provided with an upper portion (434a) of the fixed carriage surface (434) which forms a recessed surface portion in the form of a hollow semi-cylinder and a lower portion (434b) of the fixed carriage surface (434) which also forms a recessed surface portion in the form of a hollow semi-cylinder. The maximum width of the recessed surface portion in the upper portion (434a) is greater than the maximum width of the recessed surface portion in the lower end portion (434b). An inclined surface portion (434c) connects the two portions (434a; 434b). Thus, the fixed cart shown differs from that shown, for example, in Figures 14A and 14B, by having an upper portion (434a) with a recessed surface portion forming a hollow semicylinder instead of half a cone. It should be mentioned that the inclined surface (434c) forms a smaller recessed surface portion forming half a cone.Although the embodiment shown may not present the same tapered surface to guide the insertion of the fluid container into the position between the fixed carriage (430) and the head of. Petition 870260066011, dated 03 / 07 / 2026, page 86 / 186 77 / 77 drive (426), the fixed trolley shown is well adapted to receive a pump (300b) in the form of an elongated and elastic tube chamber (300b) and provide a reliable and sufficient dispensing operation.

[00220] As the person skilled in the art will appreciate, the detailed description is intended to be illustrative and many embodiments and alternatives are possible within the scope of the present invention, as defined by the appended claims. For example, the adapter assembly may adopt other forms besides those shown in the drawings, for example, the adapter assembly may comprise a unit with the first connection support and the drive piece as illustrated for embodiments in Figures 6A-6C and Figures 10A-10B, and the fixed carriage may be arranged as illustrated for embodiments in Figures 12A and 12B. Attention is drawn to the fact that the use of the adapter assembly according to the invention does not require the removal of the engagement portion (134) of the actuator used for axial compression of the pump (300a) of the first type, see Figures.

[00221] The surface of the cart, as well as the second contact surface of the drive head, can be made of soft and flexible material for soft fluid dispensing operation.

[00222] The fixed cart may also have a cart surface that may be completely in the shape of a half cone.

[00223] In addition, a dispenser with a dispensing mechanism can be provided that allows the connection support to be a non-integrated or integrated part of the dispenser while still providing all the advantages of using the first connection support, the drive part and the fixed trolley as described herein. Such a dispensing mechanism can be fixed in a fixed manner by means of a connection support similar to the first connection support. Petition 870260066011, dated 03 / 07 / 2026, page 87 / 186
