Description

This description generally refers to fluid delivery systems for dispensing cleaning and skin care products, such as soaps, gels, disinfectants, and the like. Specifically, it refers to a dispenser adapter assembly for use in the fluid delivery system to allow the use of multiple types of disposable fluid delivery packaging, refill containers, and fluid pumps in a single dispenser. The description also refers to the dispenser itself. BACKGROUND OF THE INVENTION Fluid dispensers come in various types. Specifically, for dispensing cleaning products such as soap, there is a wide variety of manually or automatically activated pumps that deliver a given quantity of the product into a user's hand. Consumer goods may include a dispensing outlet as part of the packaging, activated by a user pressing down on the top of the package. Such packaging uses a dip tube that extends below the liquid level and a piston pump that draws the liquid in and dispenses it downward through an outlet. Commercial dispensers often use inverted disposable containers that can be placed on dispensing units, mounted on walls, or recessed into bathroom countertops or similar surfaces. The pump can be integrated into the disposable container, be part of the permanent dispensing unit, or both can form a single fluid dispensing assembly. Such devices are durable, and when wall-mounted, they offer greater flexibility in the direction and amount of force required for activation. A dispensing system that uses a pump to deliver a single dose of liquid from an inverted collapsible container has been described in WO2009 / 104992. The pump consists of only a few elements, including a robust pumping chamber and regulating valves. The pump is operated by applying a lateral force to the pumping chamber, causing it to partially collapse and expel its contents through the external valve. The pumping chamber is refilled through the internal 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 backpressure due to the container's resistance to collapse. Other delivery systems use an axial force to activate the pump, that is, directed in alignment with the direction in which the fluid is supplied. In many cases, different delivery systems with different types of fluid delivery packings and pumps can be used in a given location. For example, a building might have a mix of dispensers for use with different delivery packings, requiring that all different types of fluid delivery packings be stored in the reservoir, rather than just one type. Consequently, it would be desirable to provide a delivery system that could operate in different delivery configurations, such as axial delivery as well as lateral delivery. BRIEF DESCRIPTION OF THE INVENTION It is desirable to have a supply system that is flexible in its operation and reliable when used to allow different types of fluid supply packaging, while still being simple, hygienic, environmentally acceptable, and economical to produce. The description relates, in particular, to adapter assemblies according to appended claims 1 and 35, a fluid delivery system according to appended claim 60, and a dispenser according to appended claim 70. The embodiments are set forth in the appended dependent claims, in the following description, and in the figures. Therefore, an adapter assembly is described for use in a dispenser for a fluid supply pack of a replaceable fluid container comprising a fluid reservoir and a fluid pump. The dispenser comprises a housing and a compartment therein for containing the fluid container. The dispenser has a front portion, a rear portion, and top and bottom end portions. The bottom end portion forms a supply end portion of the dispenser and comprises a user actuator, by means of which the dispenser is operated to deliver a dose of fluid from the fluid container through a nozzle in the bottom end portion. The dispenser compartment is sized to receive a fluid container that has a pump of the first type, which is an axially compressible pump, and the actuator has a coupling portion for actuating the pump of the first type by axially compressing it in a vertical direction. The adapter assembly is used in conjunction with the dispenser in order to allow the use of a fluid container that has a pump of a second type inside the dispenser, the second type being activated by its lateral compression. The adapter assembly comprises an activation portion that is movable between an unactivated position and a fully activated position when mounted on the dispenser. The activation portion comprises a first contact surface for bearing against the user actuator and a second contact surface for bearing against the pump of the second type. A user force (P) applied to the user actuator displaces the activation portion of the adapter assembly, when mounted on the dispenser, from its unactivated position to an activated position, thereby transferring an activation force (TF) from the activation portion, through the second contact surface, to the pump of a fluid container when mounted in the compartment with the adapter assembly. The pump is compressed laterally to cause the fluid to be dispensed from the fluid container. The adapter assembly also includes a first connection bracket for detachably connecting the activation part to the dispenser and / or fluid container mounted in the compartment. QZCfr ίη / ΖΖΠΖ / Ε / ΥΙΛΙ The adapter assembly further comprises a fixed trolley, configured to rest against the second-type pump. The second-type pump is positioned between the second contact surface of the actuating part and the fixed trolley, and when a user force (P) is applied to the user actuator, the pump is laterally compressed between the second contact surface and the fixed trolley, causing fluid to be dispensed from the fluid container. As used herein, an axial force for pump activation is understood to be a force directed in alignment with the direction in which the fluid is supplied. Similarly, a lateral force is understood to be a force substantially perpendicular to the direction in which the fluid is supplied. As used herein, the terms “horizontal”, “lateral” and “vertical”, “highest” and “lowest”, “downward” and “upward”, “frontal” and “rear”, and “upper” and “lower” or the like, are to be understood as observed when preparing to use a delivery system with a dispenser and fluid container, with or without the adapter assembly. The fluid container can be adapted to be filled with a liquid, such as soap, foaming soap, hand sanitizer, disinfectant, antibacterial liquid, or lotion. The flexible dispensing portion can be filled with the relevant liquid and subjected to an external force to dispense the liquid. The pumps described herein can be sized to deliver a suitable or desired volume; for example, 1 milliliter of the liquid can be dispensed after a complete dispensing stroke. Suitable materials for forming the adapter assembly include aluminum or any suitable plastic, such as olefin plastics like polyethylene or polypropylene. The adapter assembly can be formed by injection molding, 3D printing, or any other suitable method known to the skilled worker. The aforementioned materials can be used for all parts of the adapter assembly, or a combination of these materials can be used for the entire assembly or individual parts thereof. Thus, the adapter assembly enables a delivery system that can operate in different delivery configurations, namely axially and laterally. The adapter assembly makes the delivery system flexible and reliable, allowing the use of various types of fluid delivery packaging while remaining simple, hygienic, environmentally friendly, and economical to produce. The adapter assembly may include a second connection bracket for detachably connecting the fixed trolley to the dispenser and / or fluid container mounted in the compartment. The first connection bracket can also be configured to detachably connect the fixed trolley to the dispenser and / or fluid container mounted in the compartment. The second type of pump may have a robust pumping chamber. The robust pumping chamber may be an elongated, elastic tube chamber that extends downwards, in the QZCfr Ln / Zznz / E / YIAI lower portion of the fluid container, in a direction from the bottom of the fluid reservoir to a nozzle of the elastic tube chamber. The user actuator can be a user lever, configured to rotate around a first pivot. In addition, the user lever can be extended from the pivot into a user operating portion of the user lever, wherein the user actuator has a surface facing the compartment and is configured to support the first contact surface of the activation portion. The user lever can be extended downwards from the first pivot. The activation portion may comprise an elongated limb extending in a substantially longitudinal direction (L1) thereof, between two opposite ends of the limb, the first end of which is connected to the first connecting support, and the second end having an activation head. The head may be movable between the non-activated position and the fully activated position, wherein the activation head comprises the second contact surface for bearing against the pump of the second type and the first contact surface for bearing against the user actuator. The elongated limb with the activation head provides a flexible and reliable activation part, which can be configured and sized to the desired use, for example, it can be configured and sized for the specific, desired position of the contact surfaces, as well as for a desired volume to be supplied. The activation head can project outwards from the second end of the limb, in at least one direction (W; X), forming an angle with respect to the longitudinal direction (L1) of the elongated limb. The trigger head may have a dimension in a first direction (W) that extends perpendicularly to the longitudinal direction (L1) of the elongated limb, from the first contact surface to the second contact surface, which is larger compared to a dimension of the trigger head in a second direction that is parallel to a direction that is perpendicular to both the longitudinal and the first direction (W). This provides a means for forming a flat actuation head, with elongated contact surfaces, which provide adequate supply while ensuring that there is space for it in the dispenser. In one configuration, the activation element can be movably connected to the first connection bracket. Alternatively, the activation element can be rotatably attached to the first connection bracket and configured to rotate around a second pivot. This allows the activation part to move between an unactivated and an activated position, laterally, towards the trolley and the rear portion of the dispenser. The pivot can be formed by a press-fit connection between the first connecting bracket and the activation part, or it can be formed, for example, by a hinge connection or a flexible hinge. The activation part may comprise an elongated limb that extends into a QZCfr ίη / ZZΖΠZ / E / YΙΛΙ substantially longitudinal direction (L1) thereof, between two opposite ends of the limb as described above, and the first end of the elongated limb can be rotatably connected to the first connecting support and configured to rotate around the second pivot to allow movement of the trigger head, between the non-triggered position and the fully triggered position. According to another modality, the elongated limb can be a flexible limb to allow movement of the activation head, between the non-activated position and the fully activated position. This allows the activation element to move between an unactivated and an activated position by lateral movement toward the trolley and the rear portion of the dispenser. The arm can be fixed to the first connection bracket and made partially or fully flexible from the unactivated to the fully activated position. The skilled user appreciates that the arm can be made flexible by using a flexible, elastic plastic material, such as olefin plastics like polypropylene, and by selecting shapes and dimensions suitable for the purpose. Therefore, the limb can be made of an elastic material, such as polyethylene or polypropylene, and sized to be flexible and elastic. The stationary trolley has a trolley surface for supporting and receiving the pump, and the trolley surface faces the activation part. The trolley surface may include a grooved surface portion. A grooved surface provides a cavity to house a portion of the pump, which is shaped and sized to fit within the cavity. The cavity may also allow a portion of the actuator to move into the cavity when the actuator is moved to an activated position. The striated surface portion may be concave. Such a concave surface portion may fit, by way of cavity, into an elongated, elastic tube chamber. The concave surface portion can constitute the surface of the wheelbarrow. The concave surface can be concave in a horizontal plane and can form a vertical extension cavity to house a portion of the pump. In this way, the concave surface portion can match the external shape of the pump, specifically the elongated, flexible tube chamber. Thus, the cavity can have a horizontal amplitude equal to or greater than the external lateral amplitude of the pump portion designed to be housed within the cavity. The vertical extension cavity may have a maximum amplitude in an upper horizontal plane, in an upper portion of the fixed trolley, that is greater than the maximum amplitude of the cavity in a lower horizontal plane, in a lower portion of the fixed trolley. In this case, the second contact surface of the activation head may have a second upper contact surface portion that faces the upper portion of the cavity when the activation part is in the fully activated position. The second surface may, in such a QZCfr ίη / ZZΖΠZ / E / YΙΛΙ case, a second surface contact portion, lower, facing the lower portion of the cavity, when the activation part is in the fully activated position, i.e., when the lower surface contact portion has moved to its position closest to the fixed trolley. This can allow the pump to shift into the cavity during delivery, so that the pump is compressed and distorted differently along its length, ensuring proper and reliable fluid delivery. The second contact surface of the actuating part can have a maximum lateral amplitude so that it can be at least partially received in the grooved surface portion. In other words, this means that the second contact surface of the actuating part has an amplitude, in a horizontal plane, that is less than the amplitude of the cavity formed by the grooved surface portion of the trolley surface in the horizontal plane. This allows the actuating part to move, at least partially, into the cavity when it moves to the activated position, thus deforming the pump within the cavity. At least a portion of the fixed trolley surface may form a grooved surface portion that is concave and lies in the shape of a hollow half of a cone that narrows in one direction from an upper end to a lower end of the adapter assembly. Hollow media means here that a cone, a semi-cylinder or the like, has open ends. By forming a grooved surface portion shaped like half a cone, a cavity is created to receive the pump, allowing for easy and uniform insertion of the fluid container into the dispenser that holds the adapter assembly. The tapered surface portion guides the pump from the fluid container into its correct position within the dispenser, between the activation section and the fixed carriage. In addition, at least a lower portion of the fixed wheelbarrow may form a striated surface portion that is concave and forms a hollow semi-cylinder. The striated surface portion in the shape of the hollow semi-cylinder allows for the possibility of a stirrup fitted to the shape with the pump of the type that is the elongated and elastic tube chamber. The upper portion of the fixed wheelbarrow surface can form the grooved surface portion that is in the shape of a hollow half of a cone, and the lower portion of the fixed wheelbarrow can form the grooved surface portion that forms a hollow semi-cylinder. The adapter assembly can be configured so that at least a portion of the second contact surface holds the pump in the non-activated position. The second contact surface can hold the pump in the non-activated position in a pre-tensioned manner. The possibility of this stirrup can be provided by equipping the activation portion with a flexible, elastic limb that has a rest position, such that at least a portion of the activation head is received within the grooved surface portion. When the pump is inserted between the fixed trolley and the activation head, the flexible, elastic limb moves toward the QZCfr Ln / Zznz / E / YIAI front to the non-activated position, in which the activation head holds the pump in a pre-tensioned manner. A central portion of the second contact surface can extend at an angle relative to the vertical direction in an unactivated position. A portion of the upper end of the second contact surface can support the pump in the deactivated position and extend downwards and forwards from the stirrup point to a portion of the lower end of the second contact surface. In the activated position, the second contact surface can extend substantially vertically. When the adapter is used in the delivery system, this allows for the gradual compression and deformation of the pump from its upper to its lower portion. In this case, the contact between the second contact surface and the pump gradually increases from the deactivated position to the fully activated position. The contact can be gradually increased downwards, from the upper end portion of the second contact surface to the lower end portion. This allows for reliable delivery, where the fluid is delivered in a controlled manner with a low risk of fluid backflow into the pump, since the upper end portion of the second contact surface contacts the pump first, thus closing the chamber to prevent any fluid backflow. The adapter assembly may include one or more stabilizers to prevent sideways 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. The adapter assembly may further comprise a fluid container holder, configured to be received in the dispenser compartment, to hold the fluid container in a desired position in the dispenser compartment. The fluid container support provides proper containment and placement of the fluid container in the dispenser. The fluid container support can form the first connection support. The fluid container support can form the second connection support. The fluid container support may comprise one or more fluid container placement means for coupling one or more corresponding connecting portions of the fluid container and for preventing axial and / or rotational movement of the fluid container in the dispenser. The adapter assembly may further comprise one or more positioning means for coupling one or more corresponding connectors to the dispenser and for preventing axial and / or rotational movement of the adapter assembly within the dispenser. The adapter assembly may also comprise one or more positioning means for preventing incorrect placement of the adapter assembly within the dispenser. The means of attachment may be one or more protruding bolts or protrusions for QZCfr ίη / ZZΖΠZ / E / YΙΛΙ coupling of one or more corresponding cavities in the dispenser and / or for prevention of incorrect placement of the adapter assembly in the dispenser. According to another embodiment, the first connection support can be an elastic and flexible element with a cavity having a lateral dimension greater than that of the pump in a lateral direction, and in which the activation part and the fixed trolley are supported by the element and form portions that protrude on the opposite side, within the cavity, in such a way that the pump of the second type is able to be configured between the second contact surface of the activation part and the fixed trolley, in which the elastic element is safely deflected towards the pump in the non-activated position and, when a user force (P) is applied to the user actuator, the element is compressed towards the trolley so that the pump is compressed laterally, between the second contact surface and the fixed trolley, causing the fluid to be supplied from the fluid container. The elastic and flexible element can have a circular shape with a central passage opening in it, forming the cavity. An adapter assembly is also provided for use in a dispenser for a replaceable fluid container. The adapter assembly comprises an actuating part that connects to a first connection bracket to detachably connect the adapter assembly to the dispenser. The actuating part comprises a first contact surface for bearing against the user actuator of a dispenser and a second contact surface for bearing against a fluid pump. The adapter assembly further comprises a fixed trolley, connected to the first connection bracket and having a trolley surface for supporting and receiving the pump, wherein the fixed trolley and the actuating part are connected to one side of the first connection bracket, with the trolley surface facing the actuating part. The adapter assembly provides all the advantages and effects described above.

The activation head can project outwards from the second end of the limb in at least one direction (W; X) that forms an angle with respect to the longitudinal direction (L1) of the elongated limb. Qzcfr ίη / ζζηζ / Ε / γίΛΐ The activation head may have a dimension in a first direction (W) that extends perpendicularly to the longitudinal direction (L1) of the elongated limb from the first contact surface to the second contact surface that is greater than a dimension of the activation head in a second direction that is parallel to a direction that is perpendicular to the longitudinal direction and the first direction (W).

In one modality, the elongated limb can be a flexible limb to allow movement of the activation head between the non-activated position and the fully activated position. The stationary trolley may have a trolley surface for supporting and receiving the pump, wherein the trolley surface faces the activation part and comprises a grooved surface portion. The striated surface portion may be concave. The wheelbarrow surface may be concave. The concave surface can be concave in a horizontal plane and form a vertical extension cavity to accommodate a portion of the pump. The vertical extension cavity may have a maximum amplitude in an upper horizontal plane, in an upper portion of the fixed trolley, which is greater than a maximum cavity amplitude in a lower horizontal plane, in a lower portion of the fixed trolley. The second contact surface of the activation head may have a second upper contact surface portion facing such upper portion of the cavity, and a second lower contact surface portion facing such lower portion of the cavity, when the activation part is in a fully activated position. The second contact surface may have a maximum lateral amplitude so that it can be received at least partially on the striated surface portion. The activation part may include an elastic and flexible limb that has a resting position, such that at least a portion of the activation head is received within the striated surface portion. At least a portion of the wheelbarrow surface may form a striated surface portion that is concave and lies in the shape of a hollow half of a cone that narrows in one direction from an upper end to a lower end of such a striated surface portion. At least a lower portion of the fixed wheelbarrow may form a striated surface portion that is concave and forms a hollow semi-cylinder.

The reservoir 250 is a 1000 ml collapsible reservoir of the type described in WO2011 / 133085 and also in WO2009 / 104992, the contents of which are also incorporated herein by reference in full. The reservoir 250 is generally cylindrical in shape and made of polyethylene. A person 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 dispenser 100 is a pump 300 from fluid container 200, which is manually activated by a user pushing a user operating portion of actuator 124 in order to press the pump and supply fluid from the container. This description refers to a fluid supply system 1 and an adapter assembly to allow the use of different fluid containers 200, with different types of pumps 300. A fluid container 200 with a pump 300a of the first type is sized to be received in compartment 150 of dispenser 100 without the use of an adapter assembly. QZCfr ίη / ZZΖΠZ / E / YΙΛΙ pump of a first type is an axially compressible pump 300a, and the actuator 124 of the dispenser 100 has a coupling portion for actuating the pump 300a of the first type by axially compressing it in a vertical direction, towards the upper end portion 101 of the dispenser 100. A fluid container 200 with a second-type pump 300b requires the use of an adapter assembly as described. The adapter assembly adapts compartment 150 to be sized to receive a fluid container 200, which has a second-type pump, within dispenser 100, in order to allow the second-type pump to be actuated by lateral compression, thereby dispensing fluid from the fluid container. Actuator 124 can move an actuating portion of the adapter assembly toward the second-type pump 300b and laterally compress the pump. Figure 3 shows the fluid container 200 with the first-type pump 300a in a side view. As can be seen, the reservoir 250 comprises two portions: a hard portion 210 and a soft portion 212. Both portions 210 and 212 are made of the same material but have different thicknesses. As the reservoir 250 empties, the soft portion 210 folds into the hard portion 212 as the fluid is supplied by the pump assembly 300a. This construction prevents the problem of a vacuum forming within the reservoir 250. The person skilled will understand that, although this is an example of the reservoir shape, other types of reservoirs may also be used in the context of this description, including, but not limited to, bags, sacks, cylinders, and the like, whether closed or open to the atmosphere.The container can be filled with soap, detergent, disinfectant, skin care formulations, moisturizers, or any other suitable fluid, and even medications. In most cases, the fluid will be aqueous, although a knowledgeable person will understand that other substances can be used when appropriate, including oils, solvents, alcohols, and the like. Furthermore, although liquids will be referred to hereafter, the 100 dispenser can also deliver fluids such as dispersions, suspensions, or particulates. On the underside of the fluid container 200, a pump 300a of the first type is provided, having an external configuration substantially corresponding to that described in WO2011 / 133085. The fluid container has a rigid neck 214, provided with a connecting flange 216. The connecting flange 216 mates with a stationary sleeve 310 of the pump assembly 300a. The pump assembly 300a also includes a slip sleeve 312, which terminates in a bore 318. The slip sleeve 312 carries an actuating flange 314, and the stationary sleeve has a locating flange 316. Both sleeves 310 and 312 are injection-molded from polycarbonate, although a person skilled in the art will be 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 displaceable in an axial direction A by a distance D with respect to the stationary sleeve 310, in order to carry out a single doming action. Figures 4A and 4B show partial cross-sectional views through the dispenser QZCfr Ln / Zznz / E / YIAI Figure 1, 100, illustrates the first-type 300a pump in operation. According to Figure 4A, the locating flange 316 rests on front and rear shelves 130, 131 and is engaged by means of a locating groove 135 formed between the rear shelf 131 and a pin 136 on the rear portion 110. The actuator 124 rotates on the first pivot 132 toward the front portion 112 and includes a coupling portion 134 that engages below the actuating flange 314. Figure 4B shows the position of the first-type pump 300a after a user has applied a force P to the actuator 124. In this view, the actuator 124 has rotated to the left about the first pivot 132, causing the coupling portion 134 to act against the activation flange 314 with a force F, which causes it to move upward. Up to this point, the fluid delivery system comprising a fluid container 200 with a first-type pump 300b and its operation can be essentially the same as those of the existing system known from WO2011 / 133085. The fluid delivery system 1 has been described with a view to using the dispenser 100 in conjunction with the fluid container 200, equipped 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 ability to still fill the dispenser 100 with a fluid container 200 equipped with a pump 300a of the first type. A removable adapter assembly, as described herein, provides this capability. The fluid delivery system 1, the dispenser, and the adapter assembly will be further illustrated hereafter by reference to the included figures and a number of exemplary embodiments. 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 shown, for simplicity, as generally cylindrical. However, a person skilled in this field will understand that the reservoir 250 can have the same construction as described above in relation to the fluid container 200 shown in Figure 3. A person skilled in this field will also understand that any other type of reservoir 250 described above that can be used with the container 200 shown in Figure 3 can also be used with the fluid container 200 and pump of a second type. The container 200 can be filled with fluids such as soap, detergent, disinfectant, skin care formulations, moisturizers, or any other suitable fluid, as mentioned above in relation to Figure 3. On the lower side of the fluid container 200, a pump 300b of the second type is provided, which has an external configuration of an elongated, flexible tube forming a robust pump chamber 300b. 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 means of a connecting 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 fluid from escaping the fluid container when the chamber is not compressed. Similarly, a valve may be disposed between the chamber 300b and the fluid reservoir to prevent fluid from flowing back into the reservoir when the chamber is compressed. Such valves are known as QZCfr Ln / Zznz / E / YIAI on the subject. An example of such a pump and an example of a connection of the pump to the fluid reservoir are described in WO2009 / 104992. A person skilled in the art will understand that, although the elongated 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 description, including a pump 300b of a pump chamber, flexible or rigid, of a shape other than an elongated elastic tube chamber 300b. Figures 6A to 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 shown in Figure 5. The adapter assembly comprises a connecting bracket forming the first connecting bracket 410, as described herein, for detachably connecting the adapter assembly to the fluid delivery system 1. As shown in Figures 6A to 6C, the first connecting bracket 410 is a disc-shaped plate 410, 470, with a central through-hole 412 passing through the main plane of the plate. The plate has an external shape and dimensions that allow it to rest on a seat of the dispenser 100, formed by shelves 130 and 131 on the rear portion 110 of the dispenser 100, as described herein in relation to Figures 3 and 8A to 8C. The thickness of the plate is also selected to match the coupling means described in more detail herein; see Figures 8A to 8C below.The first polished connection support 410 also forms a fluid container support 470, configured to be received in compartment 150 of dispenser 100, to hold the fluid container 200 in a desired position in compartment 150 of dispenser 100. This is provided by the central through-hole 412, which has a circular shape matching the dimensions and shape of the connector cap 360 shown in Figure 5. The plate forms a seat on which the cap 360 rests, wherein a flange 368 configured at the upper end of the connector cap 360 contacts and rests on a portion of an upper surface 435 of the plate, near the through-hole 412 of the plate, and the remaining portion 367 of the connector cap 360 under the flange 368 is configured to project downward through the through-hole 412 of the plate. See Figures 5 and 6A to 6C. The person skilled in the art will understand that, although the disc-shaped plate 410; 470, with the central through-hole 412, is an example of a first connection support 410 as well as a fluid container support 470 for use in the context of the present description, other types of first connection support 410 and fluid container support 470 for the fluid container 200 may be used in the context of the illustrated adapter assembly 400, including first connection supports of shapes different from the disc-shaped plate with the central through-hole 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 having portions that rest on the seat of the shelves 130 and 131 of the dispenser 100.The person skilled in the art also appreciates that the circular passage opening 412 can take other forms, including, but not limited to, a polygonal shape that can still form the seat for the fluid container 200 and the connector cover 360 or the like. The person skilled in the art will also understand that the plate can take on various shapes. QZCfr ίη / ZZΖΠZ / E / YΙΛΙ such as one or more U-shaped plates or the like, which adopt the circular shape of the dispenser 100 in the area of ​​the shelves 130; 131, for example, two C-shaped plates, each configured to rest on the respective shelf 130; 131 and having an external shape that matches the surrounding dispenser. These plates can be held together by one or more connecting means or portions, which are disposed below or above the plates and connect to suitable plate surfaces. The adapter assembly 400 further comprises an actuating portion 420, as shown in Figures 6A to 6C. The actuating portion 420 includes an elongated limb 422 extending in a longitudinal direction (L1) therefrom, between two opposite limb ends. The first limb end 424 is configured to form a press-fit connection 416, with a corresponding cavity 414 in the disc-shaped plate, in an area between an edge and the central opening 412 of the plate, to allow the actuating portion 420 to connect to the first connection support 410. The limb 422 then extends in a direction (L1) at an angle to the principal plane of the plate. A second end of the limb carries an activation head 426, comprising a first contact surface 427 for bearing against the user actuator 124, and a second contact surface 428 for bearing against the pump 300b of the second type.The actuating head 426 projects outward from the second end of the limb in two opposite directions (W; X) that are substantially perpendicular to the longitudinal direction (L1) of the elongated limb 422, in order to form the first and second contact surfaces 428; 427, which are opposite each other. The first contact surface 427 is convex in shape to allow contact with the actuator 124 in a shape-conforming manner. The press-fit connection 416 is configured to form a second pivot 418 in the fluid delivery system 1, where the actuating portion 420 can rotate about the second pivot 418. The pivot function is provided by forming two tapered portions 423 on opposite sides of the end near the first end 424, which is press-fitted into the cavity 414 that narrows on both sides of the plate. This allows rotational movement of the end 422 along a plane. In this way, the actuating portion 420 can rotate about the second pivot 418 and allow the head to move along a rotational direction (Z) between an unactivated position and a fully activated position, enabling 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. The person skilled in this area will understand that, although the activation part 420, rotatably connected to the connection support and having the activation head 426, is an example of an activation part 420 that is movably connected to the first connection support 410 and that bears the two contact surfaces 427; 428 for use with the pump 300b of the second type, other activation parts 420 of this type may be used, including, but not limited to, activation parts formed with other head shapes, such as a head having a spherical shape and a second contact surface 428 that is concave to match the shape of the pump or convex. QZCfr ίη / ZZΖΠZ / E / YΙΛΙ to better support the full supply of fluid. The expert will also appreciate that other types of movable connections can be used, including, but not limited to, a second pivot 418 formed by a hinge connection or a flexible hinge. Instead of forming a rotatable connection between the activation part 420 and the first connecting support 410, the person skilled also envisages that the limb 422 can be fixedly connected to the first connecting support 410 and made partially or completely flexible from the non-activated position to the fully activated position in the same rotational direction (Z) as for the activation part 420, which is rotatably connected to the first connecting part 410. The person skilled will appreciate that the limb 422 can be made flexible by using a flexible, elastic plastic material from olefin plastics, such as polypropylene, and by selecting shapes and dimensions suitable for the purpose. As further shown in Figures 6A to 6C, the adapter assembly 400 comprises a fixed trolley 430 configured to rest against the second-type pump 300b when mounted in the fluid delivery system 1. The trolley 430 is fixedly connected to the disc-shaped plate 410 on the same side of the plate as the actuating portion 420, but on a side opposite the central passage opening 412 of the plate 410. The trolley 430 comprises a support structure extending from the plate 410 in a direction perpendicular to the main plane of the plate 410 to an end having a projecting portion 432 thereon, extending toward the actuating portion 420 and having a trolley surface 434 configured to support the second-type pump 300b, wherein the trolley surface 434 faces the actuating portion 420.In this configuration, the second-type pump 300b is positioned between the second contact surface 428 of the actuating part 420 and the fixed trolley 430. When a force is applied to the actuating part 420 to move the actuating head 426 toward the pump, the pump 300b is compressed between the second contact surface 428 of the actuating head 426 and the trolley surface 434, causing fluid to be dispensed from the pump. In Figures 6A to 6C, the trolley surface 434 is shown as flat. A person skilled in this field will appreciate that the trolley surface 434 can be any shape suitable for acting as a fixed trolley 430 and aligning with the second contact surface of the actuating part 420; for example, the trolley surface 434 can be inclined, rounded, convex, or concave.The trolley 430 can be divided into several trolley portions or stationary trolleys, each having a trolley surface 434. In this way, the stationary trolley 430 can be adjusted to provide the appropriate counterforce so that the triggering portion 420 provides a suitable supply action. A protruding bolt 436 is provided on a surface opposite the trolley surface 434. As will be further illustrated in Figures 8A to 8B and the related description below, this bolt 436 acts as a positioning means for coupling the corresponding cavity 142 in the rear portion 110 of the dispenser 100. This ensures correct positioning of the adapter assembly 400 in the dispenser 100 during assembly of the fluid delivery system 1. In this way, the cavity 142 forms a connector for the bolt 436. The coupling between the bolt 436 and the cavity 142 also prevents rotational movement of the adapter assembly 400 in the dispenser 100, in which the adapter assembly 400 is mounted.The expert appreciates that the positioning means may take any suitable form or shape that can aid in the placement of the adapter assembly 400 on the dispenser 100 and in preventing any movement of the adapter assembly 400 on the dispenser 100, for example, by providing a frictional contact ratio between the adapter assembly 400 and the dispenser 100, or in any other way that, in an adjustable manner, prevents rotational and / or axial movement of the adapter assembly 400 mounted on the dispenser 100. Positioning means may also be configured on other parts of the adapter assembly 400. Additional examples of positioning means will be described below. Suitable materials for forming the actuator assembly 400 can be aluminum or any suitable plastic, such as olefin plastics, for example, polyethylene or polypropylene. The adapter assembly can be formed by injection molding, 3D printing, or any other suitable method known to the person skilled in the art. The materials mentioned for forming the adapter assembly 400 can be used for all the configurations described herein. Furthermore, the described adapter assembly 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 plate thickness may be 4 mm, which provides frictional support via the coupling means 140 described below. The actuating portion extends from the plate, with a length of 38 mm, and the trolley extends from the plate, with a length of 39 mm. The trolley surface has a width of approximately 12 mm and a height of approximately 13 mm. The second contact surface has a width of approximately 13 mm and a height of 9 mm. The diameter of the elongated, elastic tube chamber may be 14 mm, and the length of the cap is approximately 56 mm. Figure 7 schematically illustrates an assembly of a fluid delivery system 1 that includes the dispenser 100 of Figure 1, a disposable container of Figure 5, and the adapter assembly 400 of Figures 6A to 6C. On the front portion 112 of the dispenser 100, the housing forms a front cover 113 that is rotatably connected to the rear portion 110 at its lower end portion 102. The front cover 113 is opened by releasing the latch 118 at its upper end and rotating the cover about its pivot at its lower end to expose the interior of the dispenser 100. The lower end portion of the rear portion 110 houses the support portion for the fluid container 200 and the pump. The adapter assembly 400 is mounted to the dispenser 100 by inserting it through a support opening 139 to retain the fluid container 200 in the lower end portion 102 of the dispenser 100.This is best shown in Figures 8A to 8C, which show magnified views of the lower portion of the inside of dispenser 100, with and without adapter assembly 400 inserted and secured in dispenser 100, as viewed from an angle above, towards the rear portion 110 of the end portion. QZCfr ίη / ZZΖΠZ / E / YΙΛΙ lower 102. As shown in Figure 8A, the support opening 139 is circular in shape and the rear shelf 131 and the locating groove 135, formed between the rear shelf 131 and the bolt 136, are arranged in the rear portion 110, as previously described herein in relation to Figure 4A and the fluid container 200 with the pump 300a of the first type. 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, in order to form a placement opening 137. The purpose of this placement opening 137 will be explained in more detail below, in relation to other embodiments of the adapter assembly 400. Beneath the support opening 139 in the lower end portion 102, which forms the part for housing the fluid pump of a fluid container 200, the rear portion 110 has two vertical flanges 141a; 141b extending forward from it. These flanges form a mounting cavity 142 between them. The adapter assembly 400 is inserted into the support opening 139 with the side of the first support / connecting plate 410 bearing the activation portion 420 and the fixed trolley 430 facing downwards, towards the lower end portion 102 of the dispenser 100, and with the fixed trolley 430 positioned towards the rear portion 110 of the dispenser 100.When the adapter is fully inserted, the first connecting bracket 410, in the form of a plate, rests on the front and rear shelves 130 and 131, and engages the positioning groove 135 between the rear shelf 131 and the pin 136 (see Figure 8B, which includes the enlarged portion thereof). Additionally, the protruding pin 436 of the fixed trolley 430 engages the positioning cavity 142 formed by the vertical flanges 141a and 141b on the rear portion 110 of the dispenser 100. This engagement ensures correct positioning of the adapter assembly 400 in the fluid dispenser 100 during its insertion.The coupling between bolt 436 and cavity 140 also prevents rotary movement of adapter assembly 400 in dispenser 100. As also shown in Figures 8A to 8C, the dispenser 100 includes coupling means 140 for retaining the disc-shaped plate in place within the dispenser 100. Since the disc-shaped plate also forms the fluid container holder 470 in this embodiment, the coupling means 140 also provides means for retaining the fluid container holder 470 when the fluid container 200 is inserted into the dispenser 100, using the dispenser 100, and removing the fluid container 200 from the dispenser 100. The person skilled in the art will appreciate that the coupling means 140 described herein can be used in conjunction with many of the fluid container holders 470 described herein. The coupling means 140 comprise an element that is movable between a non-support position and a support position. The illustrated coupling means 140 are a C-shaped element that is movable in a horizontal plane from the non-support position, as shown in Figure 8B, in a rearward direction, to the support position shown in Figure 8C. In the support position, the coupling means 140 have portions QZCfr ίη / ΖΖΠΖ / Ε / ΥΙΛΙ 140a, 140b which engage with the disc-shaped plate. The plate may have a thickness that allows the coupling means 140 to be secured in the support position by frictional interaction with the plate. The person skilled understands that the plate may also comprise a pattern of cuts or protrusions that engage with the coupling means 140. Optionally, the coupling means 140 may also be held in their support position by other means, such as by housing as described below. The person skilled understands that the coupling means 140 can take a number of forms, for example, a bayonet fitting, a screw fitting, one or more movable lugs, or a "snap" fit on the dispenser 100 into which the adapter assembly 400 or fluid container support 470 is coupled. The coupling means 140 can be a fixed component of the dispenser 100 or can be movable within the dispenser 100. If the coupling means 140 is movable within the dispenser 100, it can be spring-loaded or otherwise elastically actuated so that it moves after the insertion of the adapter assembly 400 into the dispenser 100 but returns to a coupled position after the adapter assembly 400 is correctly positioned. The coupling means 140 can also be manually actuated, as shown in the example.The coupling means 140 may comprise one or more inclined surfaces that facilitate the correct insertion and engagement of the adapter assembly 400 into the dispenser 100. The coupling means 140 may be elastically suspended in the dispenser 100 such that, when the housing 116 is opened, the coupling means 140 is held in an 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 coupling means 140 is pushed by the housing 116 against the spring into a engaged and supporting position, in which the adapter assembly engages. As illustrated schematically in Figure 7, the next step in assembling the fluid supply system 1 is to insert the fluid container 200 into the dispenser 100, which now contains the adapter assembly 400. The fluid container 200 is inserted with its pump from an elongated, elastic tube chamber 300b into the central passage opening 412 of the fluid container holder 470, which is 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 herein and also as foreseen from 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 actuating part 420 and the trolley surface 434 of the stationary trolley 430. The assembly of the fluid delivery system 1 is then completed by closing the dispenser 100 by moving the upper portion of the front cover towards the rear portion 110 and optionally locking the rear cover. The dispenser 100 is then ready for use. Figures 9A and 9B show a perspective view of a lower end portion 102 QZCfr ίη / ZZΖΠZ / E / YΙΛΙ of the fluid supply system 1 of Figure 7, when assembled into a fluid supply system 1 as shown in Figure 1, with an exploded portion of the dispenser 100 in order to show details of the interior of the fluid supply system 1, in operation. According to Figure 9A, the fluid container 200 rests on its seat in the dispenser 100, which is formed by the disc-shaped plate that forms the fluid container support 470 of the adapter assembly 400, which is detachably mounted on the dispenser 100. The fluid pump 300b of the second type, which is an elongated, elastic tube chamber 300b, extends downward from the fluid container 200, between the second contact surface 428 of the activation part 420 and the trolley surface 434 of the fixed trolley 430, to the nozzle 365 at the bottom of the dispenser 100. The nozzle 365 is positioned at the very bottom of the dispenser 100 to prevent the risk of contamination of any dispensing part after dispensing any fluid from the fluid container 200, while at the same time remaining hidden from view by the user when operating the dispenser 100.The position of nozzle 365 depends, for example, on the dimensions of fluid container 200 and its position within dispenser 100. A skilled user can determine how to position the fluid container support 470 to adjust the position of nozzle 365. The adapter assembly 400 can also be modified to adjust its position relative to pump 300b, as well as the shape of pump 300b and the maximum volume dispensed from fluid container 200. Examples of dimensions and shapes for the adapter assembly 400 have been presented previously for the embodiment shown in Figure 9A. These dimensions and shapes can be applied to other embodiments shown herein.For example, the dimensions of the activation head 426 and the fixed trolley 430 can be adjusted so that a type 300b pump, positioned between them in the dispenser 100 and in the deactivated position, remains uncompressed and undistorted, yet still provides sufficient delivery when activated. Optionally, the shapes and dimensions can be adjusted to allow the activation head 426 to rest on the pump 300b in a pre-tensioned manner in the deactivated position, thus enabling immediate and adequate delivery when the activation head 426 is moved to the activated position. In Figure 9A, the actuator 124 rotates on the first pivot 132 toward the front portion 112 and includes a contact surface 145 facing the compartment 150 of the dispenser 100 and is configured to support the first contact surface 427 of the activation part 420. The surface 145 of the actuator 124 is concave to match the convex first contact surface 427. In this view, the activation part 420 is held in its non-activated position, between the actuator 124 and the elongated, elastic tube chamber 300b that forms the pump 300b of the second type. Figure 9B shows the fluid delivery system 1, once a user has manually exerted a force P on the actuator 124, wherein the user's actuator has moved the activation part 420 and the activation head 426, from their non-activated position to an activated position, and thus transferred an activation force TF from the activation part Qzcfr Ln / zznz / E / YiAi 420, through the second contact surface 428, to the pump 300b. The pump has been compressed laterally toward the rear portion 110 of the dispenser 100 and the trolley surface 434. This has caused the fluid to be supplied downward, in a Y direction, from the fluid container 200 and its nozzle 365. In this view, the actuator 124 has rotated to the left, around the first pivot 132, to cause the dispenser 100 to be activated. Once the user removes their hand from the actuator 124, the actuator rotates to the right, toward the front portion 112, to the position it held before the user exerted force P on it. The activation part 420 then returns to its unactuated position, when the filling of the pumping chamber occurs by providing a filling force that is provided by the inherent resilience of the pumping chamber wall 300b (not shown). Figures 10A to 10B 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 shown in Figure 5. In general, the adapter assembly 400 is similar to the embodiment shown in Figures 6A to 6C, with only a few differences. A primary difference is the shape of the activation portion 420. In this embodiment, the activation portion 420 is substantially L-shaped, with an elongated limb extending longitudinally (L1) between two opposite ends. A first end 424 connects to the first connecting support 410 in any of the ways described for the embodiment in Figures 6A to 6C; that is, it can be rotatably connected or fixed to the first connecting support 410. If fixed to the first connecting support 410, the limb can be made flexible or elastic to allow movement toward the fixed trolley 430.A second end of the limb carries an actuation head 426 comprising a first contact surface 427 for bearing against the user actuator 124 and a second contact surface 428 for bearing against the pump 300b of the second type. The actuation head 426 projects outward from the second end of the limb in a direction (W) that is substantially perpendicular to the longitudinal direction (L1) of the elongated limb, forming the actuation head 426 with first and second contact surfaces 427 and 428, which are opposite each other. The first contact surface 427 is shown here as an elongated, flat surface for contact of a side flange 147 with the actuator 124 and provides a sliding surface for this flange 147 (see Figure 10C).However, the shape can be modified to allow desired contact with the flange 147 or to adopt any shape that adequately contacts an actuator surface 124 in a form-fitting manner, for example, to adopt the shape shown in Figure 6B and allow the first contact surface 427 to be in contact with an actuator surface 145 just above the flange 147. In this embodiment, the second contact surface 428 is also shown to be flat. As discussed earlier herein, it can have other shapes suitable for contacting the pump. In this configuration, the first 410 connection support forms a circular 410 sleeve instead of a disc-shaped plate. However, this shape will rest, in a form-fitting manner, QZCfr ίη / ZZΖΠZ / E / YΙΛΙ on the same seat in the dispenser 100 as the disc-shaped plate. This shape can provide some extra rigidity to the first connecting support 410. It can also provide some additional stabilization to the fluid container 200 supported by the connecting support, which is a fluid container support 470, compared to the disc-shaped plate previously mentioned herein. However, the sleeve 410; 470 provides a seat for the fluid container 200 in a manner similar to the disc-shaped element. The sleeve comprises an upper portion 411 and a lower portion 413, the upper portion 411 having an outer diameter, as well as an inner diameter, both of which are larger than the respective dimension of the lower portion 413.Thus, the sleeve forms a downward-facing circular surface 411a from the top 411, configured to rest on the front and rear shelves 130, 131 of the dispenser 100. An upward-facing circular rim surface 413a is provided in the axial extension passage opening 412 of the sleeve, configured to form a resting seat for the flange 368 of the connector cap 360 of the fluid container 200. The lower portion 413 is therefore configured to fit into the support opening 139 of the dispenser 100, below the area of ​​the shelves 130, 131. This provides some stabilization of the adapter assembly 400 when mounted on the dispenser 100, as well as for the fluid container 200 inserted therein. The sleeve also spans the fluid container 200 on its sides. In addition, a bolt 439 extends rearward from the top portion 411. This bolt 439 acts as a positioning means for mating 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 mating between the bolt 439 and the positioning opening 137 ensures correct and simple positioning of the adapter assembly 400 into the dispenser 100 during insertion of the adapter assembly 400 into the fluid dispenser 100. The mating between the bolt 439 and the positioning opening 137 also prevents both 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 shown in Figures 10A and 10C has no means of placement on the stationary trolley 430.However, as for the modality shown in Figures 6A to 6C, this modality can be used with a placement means disposed on any suitable part, for example, on the stationary trolley 430, for connecting the corresponding parts in the dispenser 100, in a suitable manner. In Figures 10A to 10B, the fixed trolley 430 is L-shaped with a substantially rigid limb, one end of which is fixedly connected to the lower part of the sleeve. The other end of the rigid limb has a trolley portion 432 extending into the second contact surface 428 of the actuating part 420, with a concave trolley surface 434 facing the actuating part 420. The concave surface matches the shape of the elongated, elastic tube chamber 300b. Furthermore, as shown, the second contact surface 428 of the actuating part 420 can have an amplitude, in a horizontal plane, that is less than the amplitude of a cavity formed in the trolley surface 434 to allow the actuating part 420 to move into the cavity when it moves to an actuated position. QZCfr Ln / Zznz / E / YIAI can provide good compression of the elongated and elastic tube chamber 300b during fluid delivery. As mentioned previously, the shapes of the different surfaces can be selected depending on the type of fluid container 200 used or the desired delivery operation. A fluid delivery system assembly 1, including the dispenser 100 of Figure 1, a disposable container of Figure 5, and the adapter assembly 400 of Figures 10A to 10B, resembles the fluid delivery system assembly 1, including an adapter assembly 400, shown in Figures 6A to 6C. Note is drawn that the embodiment shown in Figures 10A and 10B has the bolt-shaped placement means 439 in a different position than the adapter assembly 400 shown in Figure 6A, for example. As mentioned above, the bolt 439 shown in Figures 10A and 10B is configured to engage the corresponding placement opening 137, i.e., the connector formed in the rear portion 110 in the placement groove 135, as shown in Figures 8A and 10C.Therefore, the assembly of the adapter part can then be very simple by only inserting the adapter assembly 400 into the support opening 139 with the sleeve side 410 bearing the activation part 420 and the fixed trolley 430 facing downwards, towards the lower end portion 102 of the dispenser 100. The bolt 439 as well as the fixed trolley 430 should be positioned towards the rear portion 110 of the dispenser 100 in order to ensure that the bolt 439 is inserted into the corresponding placement opening 137, in the wall of the rear portion 110 and that the sleeve surface 411a rests correctly on its seats in the dispenser 100, i.e., the shelves 130; 131. The coupling means 140 shown in Figures 8A and 8C can then be used to hold the sleeve in position within the dispenser 100, as previously described herein, for coupling and supporting the disc-shaped plate. The fluid container 200 is inserted into the dispenser 100, which holds the adapter assembly 400 in a manner similar to that described above, wherein an assembled fluid delivery system 1 rests on the sleeve as described above. As illustrated in Figure 10C and in an assembled fluid supply system 1, the positions of the actuating head 426 and the trolley surface 434 are slightly lower than the corresponding parts of the embodiment shown in Figure 9A. This changes the squeezing position of the elongated, elastic tube chamber 300b. The person skilled in this regard will appreciate that any position is possible, depending on the position of the elongated, elastic tube chamber 300b and the properties of the tube chamber 300b. Furthermore, although the position is suitable for the shape, the actuating part 420 must allow the first surface to contact the rearward-facing side flange 147 of the actuator 124. The person skilled in this regard will appreciate that the head portion 426 of the actuating part 420 with the second contact surface 428 can be arranged in a more upward position.The position or shape of the fixed trolley 430 could then be adjusted according to the above. The operation of fluid supply system 1, which includes adapter assembly 400 as shown in Figure 10C, is very similar to the operation of the supply system QZCfr ίη / ZZΖΠZ / E / YΙΛΙ of fluid 1, illustrated in Figures 9A and 9B, except that the activation part 420 compresses the elongated elastic tube chamber 300b, in the lower portion thereof, and that the tube is compressed into a cavity formed by the trolley surface 434. Figures 11A to 11B 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 shown in Figure 5. This adapter assembly 400 has two separate parts instead of a single-unit adapter assembly 400, as previously described herein. This provides a simple adapter assembly 400 with a minimum of material used. The adapter assembly 400 comprises a first part forming the actuating portion 420 with a first connecting portion in the form of a side groove 410 that can be form-fitted to a rearward-facing side flange 147 of the actuator 124. The first contact surface 427 of the actuating portion 420 near the groove 410 can also be form-fitted to the surface areas of the actuator 124 surrounding the flange when the first part is properly mounted on the actuator. The overall shape of the actuating portion 420 largely corresponds to the actuating head 426, shown in Figures 10A and 10B. The second part of this embodiment includes a second connection bracket 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 activation part 420. An assembly of a fluid delivery system 1, including the dispenser 100 of Figure 1, a disposable container of Figure 5, and the adapter assembly 400 of Figures 11A to 11B, differs from the assembly of the fluid delivery system 1 including the embodiment of Figures 10A and 10B, in that the first part 420 needs to be detachably attached to the delivery system by fitting the slot 410 of the first part to a central portion of the flange 147 of the actuator 124. Attachment of the first part 420 can be carried out before or after the assembly of the second part 460, 470, and 430 to the dispenser 100. Attachment of the second part is carried out 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 assembled on it. As illustrated in Figure 11C and in an assembled fluid delivery system 1, the positions of the actuating head 426, as well as the trolley surface 434, are similar to the positions of the corresponding part shown for the embodiment in Figure 10C. A person skilled in the art will appreciate that the first part, which forms the actuating portion 420, can be configured to present the second contact surface 428 in a more upward position. The position or shape of the fixed trolley 430 could then be adjusted accordingly. The operation of fluid supply system 1, which includes adapter assembly 400 as shown in Figure 11C, is very similar to the operation of fluid supply system 1, illustrated in Figures 9A and 9B, except that the first part, which forms the part of QZCfr ίη / ZZΖΠZ / E / YΙΛΙ activation 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 activation part 420 from an unactivated position to the activated position, thereby compressing the elongated and elastic tube in the lower portion thereof, where the tube is compressed into a cavity formed by the trolley surface 434. 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 shown in Figure 5. This adapter assembly 400 is divided into three separate parts instead of forming a two-part adapter assembly 400 or a single unit. This provides a simple adapter assembly 400 with a minimum of material used. The adapter assembly 400 comprises a first part forming an actuating part 420 with a first connecting portion in the form of a side groove 410, which can be form-fitted to the rearward-facing side flange 147 of the actuator 124. The first contact surface 427 of the actuating part 420 around the groove 410 can also be form-matched to the surface areas of the actuator 124 surrounding the flange 147 when the first part is properly mounted to the actuating part 420. The overall shape of the actuating part 420 largely corresponds to the actuating head 426 shown in Figures 10A, 10B, and 11A. 11B. The second part of this modality includes a fixed trolley 430 with a second connecting support 460, in the form of a vertical slot 460a; 460b, which can be attached, in a form-fitting manner, to the vertical flanges 141a; 141b arranged in the rear portion 110 described above and shown in Figure 8A. The third part corresponds to the sleeve shown in Figures 10A and 10B which only forms a fluid container support 470. Thus, this sleeve is not connected to the activation part 420 and the fixed trolley 430. A fluid delivery system assembly 1, including the dispenser 100 of Figure 1, a disposable container of Figure 5, and the adapter assembly 400 of Figures 12A to 12B, differs from the fluid delivery 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, which forms the actuator portion 420, needs to be detachably attached to the delivery system by fitting the slot 410 of the first part to a central portion of the side flange 147 of the actuator 124.The second part forming the fixed trolley 430 needs to be detachably 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 that coincides with the height of the first part. The attachment of the third part is generally carried out as described for the adapter assembly 400 in 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. QZCfr ίη / ΖΖΠΖ / Ε / ΥΙΛΙ As illustrated in Figure 12C and in an assembled fluid delivery system 1, the positions of the actuating head 426, as well as the trolley surface 434, are similar to the positions of the corresponding parts shown for the modalities in Figures 10C and 11C. A person skilled in this regard will appreciate that the first part forming the actuating portion 420 can be configured to present the second contact surface in a more upward position. The position or shape of the fixed trolley 430 could then be adjusted accordingly. The operation of the fluid supply system 1, which includes the adapter assembly 400, shown in Figure 12C, is very similar to the operation of the fluid supply system 1 shown in Figure 11C and as illustrated in Figures 9A and 9B. Therefore, the first part forming the activation portion 420 becomes part of the actuator 124 and is movable along with the actuator 124, wherein a user force (P), applied to the actuator 124, displaces the activation portion 420 from the non-activated position to the activated position, thereby compressing the elongated, elastic tube in its lower portion, where the tube is compressed into a cavity formed by the trolley surface 434. Figure 13A illustrates one embodiment of an adapter assembly 400 comprising a first connection support 410, which is a flexible, elastic element with a cavity 480 having a lateral dimension greater than that of the pump in a lateral direction. As shown in Figure 13A, the flexible, elastic element is circular with a central passage opening 48 forming the cavity. The actuating portion 420 and the fixed trolley 430 are supported by the element and form portions that protrude from the opposite side, within the cavity, such that the pump 300b of the second type is able to be positioned between the second contact surface 428 of the actuating portion 420 and the fixed trolley 430.As illustrated in Figure 13B, the elongated, elastic pump chamber 300b of the fluid container 200 shown in Figure 5 can be inserted into the passage opening 480 of the ring and positioned between the two protruding portions, where the elastic ring safely deflects the opposing protruding portions toward the pump 300b in an uncompressed and undistorted manner, i.e., in an unactivated position. A person skilled in this field understands that the dimensions, shapes, and materials can be adjusted to provide the appropriate deflection of the structure in the unactivated position. Figure 13C shows a partial cross-sectional view of one embodiment of a fluid delivery system 1 viewed from the side. The fluid delivery system 1 comprises the fluid container 200 and the adapter assembly 400 as shown in Figure 13B. The elastic and flexible element forms the first connecting support 410 to hold the trolley 430 and the actuating part 420 in place. This support consists of two protruding portions that extend into the opening 480 of the elastic and flexible element, shown here as a spring ring. The spring ring with the protruding portions can also form a fluid container support 470. It provides a connection to the fluid container 200 and is configured to rest on front and rear portions 110 and 112 of the dispenser 100, and on a lower end portion 102 of the dispenser 100. The diameter of the spring ring is thus sized to fit only in the space between the rear portion 110 and the actuator 124. Optionally, the adapter assembly 400 QZCfr Ln / Zznz / E / YIAI may additionally comprise, or as an alternative, the 470 fluid connection support of the form shown in Figures 12A and 12B, or the like.A fluid delivery system assembly 1 shown in Figure 13C, which includes the dispenser 100 of Figure 1, a disposable container of Figure 5, and the adapter assembly 400 of Figures 13A to 13B, is simple and contains only a few steps. After opening the front cover of dispenser 100, the fluid container 200 is inserted into dispenser 100 from the top, with the elongated, flexible pump chamber inserted through the support opening 139 of dispenser 100.The elastic and flexible element is then located from the bottom of the dispenser 100, guided over the elongated and elastic tube chamber 300b of the fluid container 200 inserted into the dispenser 100 so that the tube chamber 300b is positioned between the protruding portions of the elastic ring, one of which is to be configured near the rear portion 110 and the other near the front portion 112 and the actuator 124 thereof, see Figure 13C. The height can be adjusted to provide suitable fluid connection support 470 and supply. The operation of the fluid delivery system 1, which includes the adapter assembly 400 as shown in Figure 13C, is generally similar to the operation of the fluid delivery system 1 illustrated in Figures 9A and 9B. When a user force (P) is applied to the user actuator 124, the snap ring is compressed from an unactivated position to an activated position, i.e., it is compressed toward the trolley 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 trolley 430, causing the fluid to be delivered from the fluid container 200.The skilled person understands that the dimensions, shapes, and materials can be adjusted to provide the appropriate deflection of the structure in the unactuated position and to allow a user to manually press actuator 124 to activate the fluid supply and return the snap ring to the unactuated position when the user removes their hand from actuator 124. Accordingly, the adapter assembly 400 can be made of a plastic material, such as olefin plastics, for example, polyethylene or polypropylene. Figures 14A to 14B 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 shown in Figure 5. The adapter assembly 400 shown in Figures 14A and 14B has functional and structural parts similar to the modalities shown in Figures 6A to 6C, as well as Figures 10A and 10B have some differences that will be explored in more detail below. By forming an adapter assembly 400 having the shapes of an activation part 420, a fixed trolley 430 and a first connecting support 410, as shown in Figures 14A and 14B, an adapter assembly 400 is provided that is simple to mount securely on the dispenser 100 and that shows easy and reliable insertion and use of the fluid container 200 with the pump 300b of the second type. In this configuration, the adapter assembly comprises the first 410 connection bracket, QZCfr ίη / ZZΖΠZ / E / YΙΛΙ of the present description, for detachably connecting the adapter assembly 400 to the fluid supply system 1. As shown in Figures 14A and 14B, the first connection support 410 comprises an upper portion 411 forming a disc-shaped plate portion 411 and a lower portion 413 forming the sleeve portion 413 extending downwards from the plate portion 411. The sleeve portion 413 is formed with a smaller outside diameter compared to the plate portion 411. An axial extension through-hole 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 that allow it to rest on a seat of the dispenser 100, formed by shelves 130 and 131 of the dispenser 100, as well as partially fitting with the location groove 135 on the rear shelf 131, on the rear portion 110 of the dispenser 100, as described herein in relation to Figures 3 and 16Aa 16C. As will be further explored in Figures 16A to 16C and the related description herein, a first bolt 439 extends rearward and upward from the plate portion 411. The bolt forms a placement means 439 for mating the corresponding locating groove 135 and the placement opening 137 formed in the rear portion 110, in the locating groove 135. As illustrated in this embodiment, the plate portion 411 can be thinner than the plate shown in Figures 6A to 6C. Therefore, the bolt 439 has the shape and dimensions for mating with the locating groove 135 and the placement opening 137. The shape and dimensions also allow for a thin, flexible plate portion 411, which, in turn, enables push-in functionality for mating the first bolt 439 with the locating groove 135 and the placement opening 137 when the adapter assembly 400 is mounted on the dispenser 100. The first connecting bracket 410 or just the plate portion 411 can be made of a flexible, elastic material, such as olefin plastics, for example, polyethylene or polypropylene. The use of such materials enables push-in functionality. As also illustrated, a protrusion forming a ridge portion 446 extends upward from a front portion of an upper surface 435 of the plate portion 411 on the front thereof, and along a portion of the outer periphery of the plate portion 411. The ridge portion 446 provides a means of positioning to prevent incorrect placement of the adapter assembly 400 during insertion into the dispenser 100. This will be explored in greater detail below when describing the fluid delivery system assembly 1. In addition, the coupling protrusions 447a and 447b extend upward from the upper surface 435 of the plate portion 422 near each end of the ridge portion. These coupling portions are configured and sized to engage the coupling means 140 to retain the disc-shaped plate 411 in the dispenser 100 when the adapter assembly 400 is mounted on the dispenser 100. This will be described further in relation to Figures 18A and 18B. The lower part 413 is configured to fit inside the support opening 139 of the QZCfr ίη / ZZΖΠZ / E / YΙΛΙ dispenser, under the area of ​​shelves 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 sideways and / or tilting movement of the adapter assembly during use. The stabilizers 448a-d are flat, frame-like portions extending downward from the plate portion 411 and outward from the sleeve portion 413, with two 448c; 448d located near the rear and two 448a; 448b located near the front. As shown in Figure 17, the stabilizers 448a-d are intended to be supported on vertical internal surfaces 160a; 160b in the dispenser support opening, just below shelves 130; 131. The first polished connection bracket 410 also forms a fluid container bracket 470, configured to be received in compartment 150 of dispenser 100, to hold fluid container 200 in a desired position within compartment 150 of dispenser 100. This is provided by the central through-hole 412, which has circular shapes matching the dimensions and shape of connector cap 360, as shown in Figure 5. The fluid container bracket 470 has a seat for connector cap 360 to rest on. In the axial extension through-hole 412, a circular, upward-facing rim surface 413a, formed by the sleeve portion 413, is provided. This surface 413a is configured to form a seat for the flange 368 of connector cap 360 of fluid container 200 to rest on. As also illustrated, the plate portion 411 of the first connecting bracket 410 and the fluid container support 470 comprise a second bolt 472 extending forward from the first bolt 439 into the central through opening 412. Between the second bolt 472 and the circular edge surface 413a, a positioning groove 474 is formed for coupling a connecting portion of the fluid container 200, which is the flange 368 of the connector cap 360, 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. As shown in Figures 14A and 14B, the activation portion 420 has an elongated limb 422 extending in a substantially longitudinal direction (L1) between two opposite limb ends. A first limb end 424 is fixedly connected to the plate portion 411 of the first connecting support 410, where the limb 422 is made elastic and flexible to allow movement toward the fixed trolley 430. It is understood that the limb 422 can be movably connected to the first connecting support 410 by means other than those described in relation to the modality of Figures 6A to 6C; for example, it can be rotatably connected to the first connecting support 410.A second end of limb 422 carries an actuation head 426 comprising a first contact surface 427 for bearing against the user actuator 124 and a second contact surface 428 for bearing against the pump 330b of the second type. Similar to the embodiment in Figures 10A and 10B, the actuation head 426 projects outward from limb 422 near the second end thereof in a direction (W) that is substantially perpendicular to the Q7C1? ίη / 77Ω7 / Β / YΙΛΙ longitudinal direction (L1) of the elongated limb in order to form the activation head 426 with contact surfaces, first and second, 427; 428, opposite each other. The activation head 426 is supported by a flat frame portion 440 with a first flange portion 441 at the front formed by the limb and a second flange portion 442 extending at an oblique angle, downwards and backwards, from the elongated limb 422 to a third flange portion 443 extending downwards and parallel to the flange portion 441 of the limb 422. The polished activation head 426 adopts a flat shape with a longitudinally extended second contact surface 428, formed by the third flange portion 443. The first contact surface 427 is shown here as formed by the extended portion of the limb 422 that forms the first flange portion 441 of the actuator head 426. The first contact surface 427 is a flat, elongated surface for contacting the side flange 147 on the actuator 124 and providing a sliding surface for this flange 147, see Figure 18A. The lateral width of the first contact surface 427, as shown in Figure 14B, is narrow compared to the first contact surface 427 shown in, for example, Figures 10A and 10B. This allows for a better fit of this modality of the adapter assembly 400 within the compartment 150 of the dispenser 100 without any risk of incorrectly retaining any unwanted portion within the dispenser 100 when the adapter assembly is used in the dispenser. The expert person appreciates that the shape of the activation head 426 can be modified to allow desired contact with the flange 147 or to adopt any shape to adequately contact a surface of the actuator 124 in a shape-fitting manner, for example, to adopt any other shape shown therein, such as the shape shown in Figure 6B and to allow the first contact surface 427 to be in contact with an actuator surface 145, just above the flange 147. The second contact surface 428 comprises a substantially flat, longitudinally elongated surface (L1) formed by the third flange portion 443 and an upper, outwardly rounded surface portion 444 located adjacent to the second flange portion 443. This provides a second contact surface 428 adapted to contact the elongated, elastic tube chamber 300b over a greater vertical distance compared to the adapter assemblies 400 shown previously. This will be explored in further detail below with reference to Figures 18A to 18B. As discussed earlier herein with reference to other embodiments, the second contact surface 428 can adopt other shapes suitable for contacting the pump 300b, such as a concave or convex surface. In Figures 14A and 14B, the fixed trolley 430 extends downwards from the sleeve portion 413 of the first connecting portion 410. The fixed trolley 430 comprises a splined trolley surface 434 that is concave and faces the activation portion 410. By means of the splined trolley surface 434, a cavity is provided for housing the pump 300b, which is shaped and sized to fit into the cavity. An upper portion 434a of the fixed trolley 430 forms a surface portion of grooved trolley 434a that is concave and lies in the shape of a hollow half of a cone that narrows in one direction, from the upper end to the lower end of the adapter assembly 400. A lower portion 434b of the fixed trolley 430 forms a surface portion of grooved trolley 434b that is concave and lies in the shape of a hollow half-cylinder.This concave surface portion 434b, which takes the form of a hollow semi-cylinder, matches the shape of the elongated, elastic tube chamber 300b, as shown in Figure 5. By forming the upper portion 434a into the shape of half a cone, easy and uniform insertion of the fluid container 200 into a dispenser 100 that carries the adapter assembly 400 is provided. As will be explored further below, the tapered surface portion 434a guides the insertion of the fluid container 200 into its correct position in the dispenser 100. The second contact surface 428 of the actuating head 426 has an upper contact surface portion 428a facing the surface portion 434a of the cavity, which is shaped like a hollow half of a cone, when the second contact surface portion has been moved to its position closest to the fixed trolley. The second contact surface has a lower contact surface portion 428b facing the lower portion 434b of the cavity, which is shaped like a hollow half-cylinder, when the lower contact surface portion has been moved to its position closest to the fixed trolley.This can allow a displacement of pump 300b into the cavity during supply activation, such that pump 300b is compressed and distorted in a different way along the length of the pump for proper and reliable fluid supply, i.e., pump 300b, in the form of the elongated and elastic tube chamber, will be displaced by the activation part 420, such that an upper portion of pump 300b is compressed into the upper portion 434a of the cavity which is in the shape of the hollow half of a cone and the lower portion of pump 300b will be compressed into the lower portion 434b of the cavity which is in the shape of the hollow semi-cylinder, see Figure 18B. Furthermore, as is evident, the second contact surface 428 of the activation portion 420 has an amplitude in a horizontal plane that allows the activation portion 420 to move into the cavity formed by the grooved trolley surface 434. This provides good compression of the elongated, elastic tube chamber 300b during fluid delivery. As mentioned earlier herein, the shapes of the different surfaces can be selected depending on the type of fluid container 200 used or the desired delivery operation. The activation portion 400 has a flexible, elastic limb 422 that is formed in a rest (equilibrium) position, such that a portion of the activation head 426 is received within the grooved surface portion 434 before use in the dispenser 100 and without pump 300b positioned between the activation head 426 and the stationary trolley 430. When a pump 300b is inserted between the stationary trolley 430 and the activation head 426, the flexible, elastic limb 422 moves forward from its rest (equilibrium) position to the non-activated position, in which the activation head 426 supports the pump 300b by exerting a spring force on it in a pre-tensioned manner. In this way, the adapter assembly 400 is configured so that at least one position of the second contact surface 427 supports the pump in a non-activated position. QZCfr ίη / ΖΖΠΖ / Ε / ΥΙΛΙ The stationary trolley 430 comprises a rearward-projecting flange 437 extending from and along the rear surface 438 of the stationary trolley. This flange 437 is configured to rest on a side edge 114 on the underside of the rear portion 110 of the dispenser 100, in order to support and prevent any movement of the stationary trolley during operation of the dispenser, see Figures 18A and 18B. Suitable materials for forming the adapter assembly 400 can be aluminum or any suitable plastic, such as olefin plastic, for example, polyethylene or polypropylene. The adapter assembly can be formed by injection molding, 3D printing, or any other suitable method known to the person skilled in the art. The materials mentioned for forming the adapter assembly 400 can be used for all the modalities described herein. Furthermore, the adapter assembly 400, as described, may have the following example dimensions. The circular plate portion 411 may have an outer diameter of approximately 51 mm, and the diameter of the passage opening 412 in the plate portion may be approximately 34 mm. The diameter of the passage opening 412 in the sleeve portion 413 may be approximately 31 mm. The thickness of the plate portion 411 may be approximately 2.5 mm. The sleeve portion 413 may extend from the plate by approximately 6 mm, the activation portion 420 may extend from the plate portion 411 by 54 mm, and the fixed trolley 430 may extend from the sleeve portion 413 by approximately 47 mm. The second contact surface 428 has a width of approximately 4 to 6 mm and a height of approximately 22 mm.The dimension between the first contact surface 427 and the second contact surface can be approximately 21 mm. The upper portion 434a of the fixed trolley 430, which forms the hollow half of a cone, can have a maximum width of 31 mm, and the lower portion 434b of the fixed trolley 430, which forms the hollow semi-cylinder, can have a width of approximately 13 mm and a length of approximately 27 mm. The diameter of the elongated, elastic tube chamber 300b can be 14 mm, and the length from the cap approximately 56 mm. A fluid delivery system 1 assembly 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 delivery system 1 assembly including an adapter assembly 400 shown in Figures 6A to 6C. Figure 15 schematically illustrates a fluid delivery system 1 assembly including the adapter assembly 400 of Figures 14A and 14B. After the front cover 113 is opened, the adapter assembly 400 is mounted to the dispenser 100 by inserting it through a support opening 139 to retain the fluid container 200 in the lower end portion 102 of the dispenser 100. This is best shown in Figures 16A to 16C, which show magnified views of the lower portion of the dispenser 100 interior, with and without the adapter assembly 400 inserted into the dispenser 100, as viewed from an angle from above, toward the rear portion 110 of the lower end portion. QZCfr ίη / ΖΖΠΖ / Ε / ΥΙΛΙ 102. As shown in Figure 16A, the support opening 139 is circular in shape and the back shelf 131, the locating groove 135 formed between the back shelf 131 and the bolt 116 are arranged in the back portion 110 as described below in relation to Figures 4A and 8A. As shown in Figure 16A, the location groove 135 extends posteriorly, through the opening 137 formed in the wall of the posterior portion 110 in order to form the placement opening 137. The purpose of this placement opening 137 has been described herein previously and will be explained in further detail below. The adapter assembly 400 is inserted into the support opening 139 with the side of the first connecting bracket 410 that carries the activation portion 420 and the fixed trolley 430 facing downwards, towards the lower end portion 102 of the dispenser 100, and with the fixed trolley 430 positioned towards the rear portion 110 of the dispenser 100. When the adapter is fully inserted, the first connecting bracket 410 and the plate portion 411 rest on the front and rear shelves 130 and 131, and the first bolt 439 engages the locating groove 135 between the rear shelf 131 and the bolt 136 (see Figure 16B, which includes the enlarged portion of the bolt). Additionally, the first bolt 439 also engages the placement opening 137 in the rear portion 110 of the dispenser 100.This coupling ensures correct placement of the adapter assembly 400 in the dispenser 100 during insertion of the adapter assembly 400 into the fluid dispenser 100. The coupling between the first bolt 439 and the placement opening 137 also prevents axial and rotational movement of the adapter assembly 400 in the dispenser 100. Insertion of the adapter assembly 400 is facilitated by a press-fit coupling between the first bolt 439 and the connecting parts with which it engages during insertion and when the adapter assembly is mounted in the dispenser, for example, the bolt portion 136, the locating groove 135, and the placement opening 137 in the rear portion 110 of the dispenser 100. This is made possible by the shapes of the connecting parts, such as the bolts 136 and 439, and by the inclusion of elastic and flexible parts, such as an elastic and flexible plate portion 411, an elastic and flexible first bolt 439, an elastic and flexible bolt 136, and an elastic and flexible rear portion 110 near the bolt 136. One or more of these parts may be made of an elastic and flexible material, such as olefin plastics, for example, polyethylene or polypropylene. The use of such a material enables the press-fit functionality. As mentioned previously herein, the protrusion formed by the ridge portion 446 extending upward from a portion of the upper surface 435 of the plate portion 411 on the front thereof provides a means of positioning to prevent incorrect rotational placement of the adapter assembly 400 during insertion into the dispenser 100. The person skilled appreciates that the portion with the ridge has a vertical dimension / thickness that does not permit this portion to be positioned toward the rear portion 110 for engagement with the locating groove 135, between the rear shelf 131 and the bolt 136. As illustrated in Figures 16A and 17, the four stabilizers 448a-d of the adapter assembly guide the adapter assembly 400 into the correct position in the dispenser by contact of the vertical internal surfaces 160a; 160b in the support opening 139 of the dispenser, just below the shelves 130, 131 during insertion. When the adapter is fully inserted, the stabilizers 448a-d are supported on the vertical internal surfaces 160a; 160b, where they prevent sideways movement and / or tilting of the adapter assembly during dispenser operation. As also shown in Figures 16A to 16C, the dispenser 100 includes coupling means 140 for retaining the first connection bracket 410 and the disc-shaped plate portion 411 thereof in the dispenser 100. Since the first connection bracket 410 also forms the fluid container support 470 in this embodiment, the provision of the coupling means 140 also provides means for retaining the fluid container support 470 in place when the fluid container 200 is inserted into the dispenser 100, when the dispenser 100 is used, and when the fluid container 200 is removed from the dispenser 100. The coupling means 140 has been described herein previously in relation to Figures 8A to 8C. The coupling means 140 is in the form of a C-shaped element, which is movable in a horizontal plane from the unsupported position shown in Figure 16B in a rearward direction to the supported position shown in Figure 16C. In the supported position, the coupling means 140 has portions 140a and 140b that engage with the disc-shaped plate portion and upwardly projecting portions 447a and 447b on the 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 coupling means 140 as described herein.In the embodiment shown, the coupling means is held in its support position by the housing, as the coupling means 140 is elastically suspended in the dispenser 100, such that when the housing 116 is opened, the coupling 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 closed, the coupling means 140 is pushed by the housing 116 against the spring into a coupled and support position, in which the adapter assembly is engaged. In this way, the coupling means 140 does not need to be secured in the support position by frictional interaction with the plate. As best seen in Figures 18A and 18B, the rearward-projecting flange 437, which extends from and along the rear surface 438 of the fixed trolley of the adapter assembly 400 that has been inserted into the dispenser, is supported on the side rim 114 on the underside of the rear portion 110 of the dispenser 100 in order to provide support and prevent any movement of the fixed trolley during operation of the dispenser 100. As illustrated schematically in Figure 15, the next step in assembling the fluid delivery system 1 is to insert the fluid container 200 into the dispenser 100, which now contains the adapter assembly 400. The fluid container 200 is inserted with its pump from an elongated, flexible tube chamber 300b into the central passage opening 300b, toward the central passage opening 412 of the fluid container holder 470, until the connector cap 360 of the QZCfr ίη / ZZΖΠZ / E / YΙΛΙ fluid container 200 with its flange 368 rests on the seat formed by the adapter assembly 400 in the dispenser 100 described herein previously and also provided from Figure 18A. As described above, the plate portion 411 of the first connecting bracket 410, which forms the fluid container support 470, is provided with a fluid container placement means 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 fluid container placement means is formed by the placement groove 474, located between the second bolt 472 and the circular edge surface 413a of the fluid container support 470. This placement groove 474 is configured to engage the flange 368 of the connector cap 360, which forms a connecting portion for the placement groove 474.As a fluid container 200 is inserted into position in the dispenser and adapter assembly, a press-fit arrangement between the flange 368 of the connector cap 360 and the second bolt 472 allows the flange 368 to engage the positioning groove 474 and rest on the circular rim surface 413a of the fluid container holder 470 (not shown). This press-fit arrangement is made possible by the shapes of the connecting parts, such as the second bolt 472 having an upwardly rounded surface portion, and by the provision of elastic and flexible parts. Thus, any part forming the coupling portion or portions near the parts can be made of a flexible and elastic material, such as olefin plastics, for example, polyethylene or polypropylene. The use of such a material enables the press-fit functionality. Figure 18A also illustrates that the fluid container 200 is inserted so that the elongated elastic tube chamber is positioned between the second contact surface 428 of the activation part 420 and the trolley surface 434 of the fixed trolley 430. The insertion of the elongated elastic tube chamber 300b in this position is supported by the grooved surface portion 434a, which is shaped like half a cone, wherein the tapered surface portion guides the tube chamber 300b of the fluid container 200 into the position it should have in the dispenser 100, i.e., to be located between the activation part 420 and the fixed trolley 430.In the inserted position, the elongated elastic tube chamber 300b is partially received within the cavity formed by the grooved trolley surface 434, which is in the shape of a hollow half of a cone, and the lower grooved trolley surface portion 434b, which is concave and forms a hollow semi-cylinder, see Figures 16A to 16C and 18A. As shown in Figure 18A, the concave surface portion 434b, which takes the shape of a hollow semi-cylinder, matches the shape of the elongated elastic tube chamber 300b. The assembly of the fluid delivery system 1 is then completed by closing the dispenser 100 by moving the upper portion of the front cover towards the rear portion 110 and optionally locking the cover to the rear portion. The dispenser 100 is then ready for use. Figures 18A and 18B show a perspective view of a lower end portion 102 of the fluid delivery system 1 of Figure 15, when assembled into a fluid delivery system as shown in Figure 1, with a portion of the dispenser 100 disassembled in order to QZCfr Ln / Zznz / E / YIAI show details of the interior of fluid supply system 1 in operation. According to Figure 18A, the fluid container 200 rests on its seat in the dispenser 100, which is formed by the first connecting bracket 410 forming the fluid container support 470 of the adapter assembly 400 shown in Figures 16A and 16B, which is detachably mounted on the dispenser 100. The fluid pump 300b of the second type, which is an elongated and elastic tube chamber 300b, extends downwards from the fluid container 200 and between the second contact surface 428 of the activation part 420 and the trolley surface 434 of the fixed trolley 430 to the nozzle 365 at the bottom of the dispenser 100.Nozzle 365 is positioned at the very bottom of dispenser 100 to prevent contamination of any part of the dispenser after dispensing fluid from the fluid container 200, while remaining hidden from view during operation. The position of nozzle 365 depends on factors such as the dimensions of fluid container 200 and its position within dispenser 100. A skilled user can adjust the position of the fluid container holder 470 to accommodate nozzle 365. The adapter assembly 400 can also be modified to adjust its position relative to the pump, as well as the pump's shape and the maximum volume dispensed from fluid container 200.Some examples of dimensions and shapes of the adapter assembly 400 have been presented here previously for the embodiment now shown in Figure 18A. These dimensions and shapes can be provided for other embodiments shown here. For example, the dimensions of the activation head 426 and the fixed trolley 430 are adjusted so that a pump placed between them in the dispenser 100, in the non-activated position, can be in a desired shape to provide reliable and sufficient dispensing operation when activated. In Figure 18A, the actuator 124 rotates on the first pivot 132 toward the front portion 112 and includes the rearward-facing side flange 147 of the actuator 124, which has a front edge facing the dispenser compartment 150 and is configured to support the first contact surface 427 of the activation portion 420. In this view, the activation portion 420 is held in its non-activated position between the actuator 124 and the elongated, elastic tube chamber 300b that forms the pump 300b of the second type. As illustrated, the activation portion 422 and its elongated end 422 move forward from their rest (equilibrium) position to the non-activated position, in which the activation head 426 supports the pump 300b by 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 contact surface support and slightly deform the elongated, elastic tube chamber 300b in a prestressed manner. The central portion and the lower portion 428b of the second contact surface 428 extend forward and downward in the unactivated position. Figure 18B shows the fluid delivery system 1 once a user has manually exerted a force P on the actuator 124, wherein the user actuator has moved the activation part 420 and the activation head 426 from their unactuated position to their activated position QZCfr iη / ZZΖΠZ / E / YILI activated, and has thus transferred an activation force TF from the activation portion 420, through the second contact surface 428, to the pump 300b. The pump has been compressed laterally towards the rear portion 110 of the dispenser 100 and the trolley surface 434. This has caused the fluid to be supplied downwards, in a Y direction, from the fluid container 200 and its nozzle 365. In this view, the actuator 124 has rotated clockwise, around the first pivot 132, to cause the activation of the dispenser 100. During the movement of the activation head 426 to the activated position, the contact between the second contact surface 428 and the pump 300b gradually increases from the non-activated position to the fully activated position.The contact area 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 delivery operation, where the fluid is delivered in a controlled manner, with a low risk of fluid backflow into the pump 300b, since the upper end portion 428a of the second contact surface 428 first contacts the pump 300b, allowing the elongated, elastic tube chamber 300b to close against any fluid backflow. Once the user removes their hand from actuator 124, the actuator rotates to the left, toward the front portion 112, to the position it held before the user applied force P. The activation portion 420 then returns to its non-activated position, as shown in Figure 18A, when the pumping chamber is filled by the filling force provided by the inherent resilience of the pumping chamber wall (not shown). Figures 18A, 18B to 22 show embodiments of the adapter assembly 400 according to the description, 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 shown in Figure 5. The adapter 400 assembly modes shown in these Figures are variants of the mode shown in Figures 14A and 14B, with only a few differences. As illustrated in Figures 19 to 22, the disc-shaped plate portion 411 can take on shapes other than the one basically described above in relation to the form shown in Figures 14A and 14B. As shown in Figures 19 to 21, the plate portion 411 can take on a partially circular shape with two straight edges 415a; 415b connecting convex front and rear portions of the plate portion 411. This shape also allows the plate portion 411 to rest on the front and rear shelves 130; 131 in the dispenser 100.The person skilled in this field will understand that, although this form, as well as the circular disc form of the plate portion 411 with the central through-hole 412, are examples for use in a first connection bracket 410 and a fluid container bracket 470 in the context of this description, other types of first connection brackets 410 and fluid container brackets 470 may also be used in the context of the illustrated variants of the adapter assembly 400 described herein. These types include first connection brackets 410 of portions with different forms. Qzcfr Ln / zznz / E / YiAi of disc-shaped plate 411, with the central passage opening 412, Including, but not limited to, a portion of plate or sleeve having, in part, a circular shape with more than two straight edges or an external polygonal shape, such as a hexagonal or octagonal shape, which still have portions resting on the seat of the shelves 130 and 131 of the dispenser 100. The person skilled also appreciates that the circular passage opening 412 may take other forms which include, but are not limited to, a polygonal shape which may still form the seat for the fluid container 200 and the connector cap 360 or the like. As illustrated in Figures 19 to 21, the protruding bolt 439 can be formed in different ways. As shown in Figure 19, the bolt 439 is part of an elongated, flexible, and elastic element that extends upward and backward from the sleeve portion 413 of the first connecting bracket 410, through an opening 471 formed in the rear of the first connecting bracket 410, to a position on the rear of the plate portion 411. The flexible and elastic element allows for press-fit engagement with the bolt 136, the locating groove 135 between the rear shelf 131 and the bolt 136 in the rear portion 110 of the dispenser 100, and in the placement opening 137 formed in the rear portion 110, in the locating groove 135. In Figures 20 and 21, bolt 439 extends rearward and upward from a rear edge of plate portion 411 to engage the corresponding locating groove 135 and the placement opening 137 formed in rear portion 110, in the locating groove 135. An opening 119 is formed in the rear of plate portion 411. This opening 119 is formed to provide a flexible portion between the opening 119 and bolt 439 in order to allow press-fit engagement between bolt 439 and the locating groove 135 between the rear shelf 131 and bolt 136 in rear portion 110 of dispenser 100, and the placement opening 137 formed in rear portion 110 in the locating groove 135. As also illustrated in Figures 19 to 22, the coupling protrusions 447a; 447b extending upward from the upper surface 435 of the plate portion 422, near each end of the ridge portion 446, may be formed differently than shown for the embodiment in Figures 14A and 14B. The coupling protrusions shown 447a; 447b are all configured and sized to couple the coupling means 140 in order to retain the disc-shaped plate 411 in the dispenser 100 when the adapter assembly 400 is mounted on the dispenser 100, see Figures 18A and 18B. As shown in Figures 19 to 22, the activation parts 420 are also slightly different from those shown in Figures 14A and 14B. In Figures 19 and 20, the activation part 420 has the longitudinally extending, elongated limb 422 fixedly connected to the plate portion 411 of the first connecting support 410, wherein the limb 422 is made flexible and elastic to allow movement toward the fixed trolley 430. The expert appreciates that the limb 422 can be movably connected to the first connecting support, as described in relation to the embodiment in Figures 6A to 6C. Similar to the embodiment in Figures 14A and 14B, the activation head 426 has first and second contact surfaces, 427a-b; 428, opposite each other.The activation head 426 is held by two flat half-frame portions 440a; 440b that extend between the first contact surfaces 427a; 427b formed by two edges of half-frame portions 440a, 440b and the second contact surface 428 formed by a portion connecting half-frame portions 440a, 440b. As for the embodiment shown in Figures 14A and 14B, the first contact surfaces 427a and 427b are configured to contact the side flange 147 on the actuator 124 of the dispenser 100 and provide sliding surfaces for this portion of the flange 147 during operation of the dispenser 100. The illustrated actuator head 426 is wider than that shown in Figures 14A and 14B, having two first contact surfaces 427a and 427b instead of one, in order to provide an alternative for good and reliable operation during fluid dispensing. As shown, the second contact surface is also made wider than that shown in Figures 14A and 14B.However, the expert person 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 delivery operation for the fluid to be delivered. The activation parts 420 shown in Figures 21 and 22 are very similar to those shown in Figures 14A and 14B, except that the activation head shown 426 lacks the first flange portion 441 at its front. Therefore, the first contact surface 427 is formed by a lip at the front of the flat weave portion 440. This lip 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 operation of the dispenser 100. Therefore, the activation head 426 has a narrow, flat shape that can be easily received in the compartment 150 of the dispenser 100 and provides suitable dispensing operation. The width of the flat weave portion 440 and its border 427 can be adjusted to provide a suitable contact surface for the side flange 147. Figure 23 shows an embodiment that is also a variant of the embodiments described above in relation to Figures 14A to 14B and 18A, 18B to 22. This embodiment has a first connecting support 410 with a plate portion 411 that is partially circular with two straight edges 415a; 415b connecting convex front and rear portions of the plate portion 411. The plate portion 411 is made flat, and the bolt 136 extends from a rear edge of the plate portion. This first contact support 410 has many functional and structural similarities to the circular sleeve shown in Figures 10A and 10B. The adapter assembly has a similar activation part 420 to that of the modalities shown in Figures 21 and 22. As shown in Figure 23, the fixed trolley 430 is provided with an upper portion 434a of the fixed trolley surface 434 forming a grooved surface portion in the shape of a hollow semi-cylinder and a lower portion 434b of the fixed trolley surface 434 also forming a grooved surface portion in the shape of a hollow semi-cylinder. The maximum amplitude of the grooved surface portion in the upper portion 434a is greater than the maximum amplitude of the grooved surface portion in the lower portion 434b. An inclined surface portion 434c connects the QZCfr Ln / Zznz / E / YIAI two portions 434a; 434b. Thus, the fixed trolley shown differs from that shown, for example, in Figures 14A and 14B, in that it has an upper portion 434a with a grooved surface portion forming a hollow semi-cylinder instead of half a cone. It should be mentioned that the inclined surface 434c forms a smaller grooved surface portion, which forms half a cone. Although the embodiment shown may not have the same tapered surface for guiding the insertion of the fluid container into the position between the fixed trolley 430 and the actuating head 426, the fixed trolley shown is well adapted to receive a pump 300b in the form of an elongated, flexible tube chamber 300b and to provide sufficient and reliable delivery operation. As the expert will appreciate, the detailed description is intended to be illustrative, and many embodiments and alternatives are possible within the scope of this description, as defined by the appended claims.
