[0002] CROSS-REFERENCE TO RELATED APPLICATIONS

[0003] This application claims priority to U.S. application No. 17 / 496,192, filed on October 7, 2021, entitled “Dispenser System,” the entire contents of which are incorporated herein by reference in their entirety. Technical Field

[0004] The present disclosure relates to a dispenser system for dispensing a fluid, the dispenser system including a dispenser and an adapter configured to cooperate with the dispenser to support a cartridge containing the fluid. Background Art

[0005] Dispensers are used in a variety of environments, ranging from public bathrooms to office buildings, hotels, hospitals, restaurants and other public or private places. Typically, a dispenser consists of a dispenser housing and a refillable and / or replaceable reservoir (e.g., box) that holds the fluid product to be dispensed.

[0006] Depending on the location, a dispenser may need to dispense a specific type of fluid product, such as soap, disinfectant solution, shampoo, etc. Furthermore, it is important that the fluid product dispensed is of the desired quality and / or grade. This is particularly important in situations where hygiene is paramount, such as in a hospital setting, where it is important that only the intended fluid is dispensed from the dispenser.

[0007] To this end, the dispenser may be configured to operate specifically with a cartridge containing the specific fluid required, which often results in the dispenser having a complex mechanism with multiple parts for preventing the dispenser from being used with the wrong type of cartridge (ie, an incompatible cartridge).

[0008] However, manufacturing corresponding dispensers specifically for a particular cartridge type is expensive and requires a large product range.

[0009] Furthermore, a different grade or type of fluid product may be desired, which may require replacing the entire dispenser with a new one compatible with the new cartridge, or replacing a mechanism within the dispenser, both of which are expensive and inefficient.

[0010] It is an object of the present disclosure to address or alleviate at least some of these problems. Summary of the Invention

In some aspects, the center portion includes a first biasing member configured to resist movement of the first leg and the second leg about the central flexure axis. In some embodiments, the adapter is configured to couple to a pump drive flange of a cassette containing a fluid to be dispensed.

[0017] In yet another aspect, a dispenser includes a dispenser body having an interior cavity in which a first chassis is configured to translate relative to a second chassis along a central axis. Furthermore, the dispenser includes a cartridge comprising a container and a pump including a drive flange defining a drive diameter. Furthermore, the dispenser includes an adapter having a pair of legs configured to couple to the drive flange and the first chassis, wherein the adapter and the drive flange are configured to prevent the drive flange from translating independently of one another.

[0018] In some embodiments, the first leg of the adapter includes a first retention protrusion and a second retention protrusion, the second retention protrusion is configured to contact the drive flange, and the first retention protrusion is configured to contact the first chassis. In some aspects, the drive flange defines a diameter, the adapter defines a retention width, and the diameter is configured to correspond to the retention width to achieve a snap fit between the adapter and the drive flange.

[0019] In some embodiments, the actuator is configured to be depressed to translate the first chassis, adapter, and drive flange in a first direction, at least one spring is configured to translate the first chassis, adapter, and drive flange in a second direction opposite to the first direction, and the actuator is configured to be depressed in a third direction different from the first direction and the second direction.

[0020] On the other hand, the method for providing a dispenser for distributing fluids includes providing a dispenser body and providing a first adapter, the first adapter being configured to couple a first box to the dispenser body. The first adapter defines a first size corresponding to a portion of the first box. In addition, the method includes providing a second adapter, the second adapter being configured to couple a second box to the dispenser body. The second adapter defines a second size corresponding to a portion of the second box. In some embodiments, the first size is different from the second size, and the first adapter and the second adapter are configured to be flexible.

[0021] In some embodiments, the first adapter and the second adapter are substantially identical to each other except for the first and second dimensions. In some aspects, the first and second cassettes differ with respect to at least one of the pump, the cassette body, and the fluid to be dispensed. In some embodiments, the first dimension of the first adapter does not correspond to a portion of the second cassette, and the second dimension of the second adapter does not correspond to a portion of the first cassette.

[0022] In some aspects, the first cartridge is capable of dispensing fluid when the first adapter is operably received within the dispenser body. In some embodiments, only one of the first adapter and the second adapter can be operably received within the dispenser body. In some aspects, the dispenser body includes a front cover rotatably mounted to the rear body about a first hinge axis, and the front cover includes an actuator rotatable about a second hinge axis spaced apart from the first hinge axis.

[0023] In some embodiments, the actuator is configured to contact a movable chassis within the dispenser body when the front cover is mounted to the rear body in a closed position. In some aspects, in the closed position, when the actuator rotates about the second hinge axis, the movable chassis translates within the dispenser body. In some embodiments, in the closed position, when the actuator rotates about the second hinge axis, the first adapter or the second adapter translates along with the movable chassis.

[0024] On the other hand, a kind of dispenser system is provided, this dispenser system comprises the dispenser for distributing fluid, this dispenser system comprises a dispenser main body, this dispenser main body at least partially limits the inside of dispenser, the inside of this dispenser is configured to accommodate a kind of box, and described box holds fluid to be distributed.In addition, the dispenser system comprises a mobile chassis that is configured to move relative to main body and an adapter that is configured to be removably coupled to the mobile chassis to form a supporting structure for supporting the predetermined type of box in the dispenser. For this reason, the adapter cooperates with the mobile chassis of the dispenser to form a supporting structure for supporting the box in the dispenser. Therefore, the dispenser with a single mobile chassis design can be suitable for using together with the desired box type by using an adapter. Therefore, for the various box types corresponding to various fluid products, a single dispenser and mobile chassis design can be used, and by using corresponding adapters it is suitable for being compatible with specific box types. Therefore, dispenser is efficiently manufactured, cost-effective and has merged a large number of components, can be used together with various box types simultaneously.

[0025] In some embodiments, the adapter and the mobile chassis are coupled together to form a support structure for supporting a specific cartridge type to maintain the integrity of the dispenser so that the user receives the intended fluid during use. In addition, when a cartridge becomes depleted, a cartridge of the exact same type can replace the depleted cartridge for operable use within the dispenser. Thus, the adapter and the mobile chassis are compatible with the cartridge type and / or specific cartridge.

[0026] Furthermore, if the dispenser needs to dispense different types of fluids, the adapter can be replaced with an alternative adapter configured to support different types of cassettes, without having to replace the entire mobile chassis or dispenser. Thus, the dispenser can be reconfigured to operate with different types of cassettes, if necessary, and this reconfiguration can be performed in place. Furthermore, if a component is lost or damaged, the adapter can be replaced without having to replace the mobile chassis or dispenser. This creates a simple, universal dispenser system that can be efficiently reconfigured by maintenance professionals, which is more cost-effective and less wasteful.

[0027] It should be understood that by supporting the cassette with the support structure, the cassette is coupled to the mobile chassis so that at least a portion of the cassette is fixed to move with the mobile chassis. The adapter and mobile chassis are coupled together so that movement of the mobile chassis relative to the main body causes movement of the adapter relative to the main body. When the cassette is supported by the support structure, movement of the mobile chassis thus causes corresponding movement of the cassette.

[0028] In some embodiments, both the mobile chassis and the adapter must be present in the dispenser to support the predetermined type of box in the dispenser for dispensing. To this end, the mobile chassis and the adapter cooperate to support the predetermined type of box. Without any of these components, no support structure is formed, and the predetermined type of box cannot be supported in the dispenser for dispensing.

[0029] In some embodiments, the adapter is configured to be removably coupled to the mobile chassis so that the movement of the mobile chassis is directly converted into the movement of the adapter within the entire range of movement of the mobile chassis. For this reason, there is no idle motion between the mobile chassis and the adapter. In some embodiments, the mobile chassis is configured to move vertically during normal use. In some embodiments, the mobile chassis is not configured to be removed from the dispenser. In some embodiments, the mobile chassis is configured to be permanently coupled to the dispenser body.

[0030] In certain embodiments, the supporting structure limits the opening for receiving the box. In certain embodiments, the adapter is configured to bend towards and away from the direction of the opening. In certain embodiments, the adapter is configured to bend towards and away from the opening defined by the supporting structure, and this opening is configured to receive the box. In this way, the adapter is configured to bend towards and away from the box in use, thereby being convenient to positioning the box in the supporting structure so that the box is effectively loaded in the main body. This provides a simple and effective way for the box to be loaded in the dispenser housing, while the quantity and the total number of components that will comprise the moving parts of the supporting structure are kept to a minimum. For example, because the adapter is configured to bend, no extra spring is needed, thereby reducing the required number of components and the amount of metal for the construction dispenser system.

[0031] In some embodiments, the adapter is configured to flex relative to the mobile chassis when the adapter is coupled to the mobile chassis. In other words, the adapter is configured to flex when coupled to the mobile chassis as viewed from a reference frame of the mobile chassis. The fluid may include soap, shampoo, hand soap, lotion, cleanser, or other desired fluid. As used herein, the term "soap" is intended to include any liquid detergent or cleaning product suitable for dispensing from a fluid dispenser.

[0032] In some embodiments, the support structure is configured to specifically support a predetermined type of cartridge. Thus, the dispenser system can be used specifically with the correct cartridge type, thereby ensuring that the dispensed fluid is as needed and intended.

[0033] In certain embodiments, the adapter is configured to engage with the box snap fit. In certain embodiments, the supporting structure is configured to engage with the box snap fit. In this way, a simple and easy device for supporting the box in the dispenser is provided. Should be understood that the adapter is configured to promote the snap fit function of adapter and box by bending in the direction towards and away from the opening of the supporting structure.

[0034] In some embodiments, the adapter includes a latching element for engaging the corresponding portion of the cassette. In this way, the corresponding portion of the cassette is coupled to the support structure for movement with the mobile chassis. In some embodiments, the latching element is biased toward engagement with the cassette. This provides a simple and effective means of retaining the cassette in place. In other words, the cassette is more effectively coupled to the support structure.

[0035] In some embodiments, the adapter includes at least one resilient leg extending from a central portion, wherein the leg is configured to bend about the central portion. In some embodiments, the adapter includes a pair of resilient legs configured to bend about the central portion. Thus, the resilient legs facilitate bending of the adapter toward and away from the opening of the support structure. This provides an adapter having a simple structure that is configured to bend. In some embodiments, the resilient legs include locking elements.

[0036] In some embodiments, the adapter includes a pair of legs symmetrically arranged about a central portion. In some embodiments, each of the pair of legs includes a locking element. Thus, the resilient legs are configured to flex toward and away from an axis of symmetry of the adapter, such that the locking element is thereby arranged to move toward and away from the axis of symmetry.

[0037] When box is loaded in dispenser and adapter is coupled to mobile chassis, this pair of legs and therefore the latch element that is arranged thereon are configured to bend towards and away from the direction of the opening of supporting structure, that is, towards and away from box, for example, the longitudinal axis of box.By providing relative latch element in this way, can realize box is effectively remained in position.In certain embodiments, a pair of latch element is provided, for example radially relative to each other with respect to the axis of symmetry of the opening of adapter and / or supporting structure.Therefore, described a pair of latch element can be used for the part of clamping box to be remained in position.

[0038] In some embodiments, the locking element includes a protrusion that protrudes toward the axis of symmetry of the adapter. In some embodiments, where a pair of locking elements are provided, the locking elements include protrusions that are configured to extend toward each other. In some embodiments, at least a portion of the legs include an arched profile to facilitate bending of the adapter. Thus, the profile of the adapter is formed to promote the flexing ability of the adapter so that no additional springs or components are required. This reduces the number of components required in the dispenser system and also reduces the amount of metal required to manufacture the dispenser. The arched profile also facilitates the snap-fit ​​engagement of the lock with the box. In some embodiments, the support structure includes a retaining device for coupling the adapter to the mobile chassis. Thus, the adapter and the mobile chassis are reliably coupled together.

[0039] In some embodiments, the retaining arrangement comprises a snap-fit ​​arrangement. In some embodiments, the retaining arrangement is biased toward the coupling of the adapter and the mobile chassis. Thus, a simple and effective manner of coupling the adapter and the mobile chassis is provided. In some embodiments, the adapter comprises a resiliently biased structure comprising a retaining element for coupling to a corresponding retaining element of the mobile chassis, wherein the retaining element of the adapter and the corresponding retaining element of the mobile chassis comprise the retaining arrangement.

[0040] In some embodiments, the retaining arrangement includes a protrusion and a corresponding hole. For example, the retaining element of the adapter may include a protrusion, and the corresponding retaining element of the mobile chassis may include a hole, or vice versa. In some embodiments, the retaining element of the adapter is disposed at the free end of the elastic leg. In some embodiments, the retaining element of the adapter is disposed at the free end of each elastic leg.

[0041] In certain embodiments, the mobile chassis and the adapter include a positioning device for positioning the adapter in the correct position relative to the mobile chassis. Therefore, the correct positioning of the adapter relative to the mobile chassis can be achieved. This helps the correct positioning of the box in the dispenser. In certain embodiments, the positioning device includes a projection and a corresponding hole or recess. For example, the adapter can include a projection, and the mobile chassis can include a hole or recess, or vice versa.

[0042] In some embodiments, the mobile chassis includes a cavity for receiving the adapter. In some embodiments, the positioning device includes a positioning element for the adapter and a corresponding positioning element for the cavity. In some embodiments, the positioning element for the adapter is provided by a central portion of the adapter. This facilitates efficient positioning of the adapter relative to the mobile chassis.

[0043] In some embodiments, the positioning means comprises a protrusion and a corresponding hole or recess. For example, the positioning element of the adapter may comprise a protrusion and the corresponding positioning element of the cavity may comprise a hole or recess, or vice versa. In some embodiments, the adapter is configured to be operably coupled to the mobile chassis such that the adapter is fixed to move with the mobile chassis, and the adapter is configured to engage a portion of the cassette such that movement of the mobile chassis is directly translated into movement of the portion of the cassette over the entire range of movement of the mobile chassis.

[0044] In some embodiments, the mobile chassis and the adapter are configured to move together so that a portion of the box supported by the mobile chassis and the adapter moves together with the mobile chassis and the adapter. In some embodiments, the box is supported by the mobile chassis and the adapter so that the movement of the mobile chassis is converted into the movement of a portion of the box within the entire range of movement of the mobile chassis. Therefore, there is no motion loss between the portion of the box and the mobile chassis. This results in a consistent dose of fluid being dispensed from the dispenser.

[0045] In some embodiments, the adapter comprises a single component. Thus, a dispenser system with a simple structure is provided. In addition, if the dispenser system needs to be used with different types of boxes, this can be achieved simply by replacing a single component (i.e., the adapter) with an adapter corresponding to the desired box type. This reduces the number of components required to manufacture the dispenser system in the first instance and also reduces the number of components that need to be replaced when the dispenser needs to be reconfigured to be used with different box types. This is more cost-effective and reduces waste.

[0046] In some embodiments, the adapter is formed of a plastic material. This facilitates the elastic properties of the adapter and also reduces the amount of metal required to produce the dispenser system. In some embodiments, the adapter is a first adapter that is configured to be removably coupled to the mobile chassis to form a support structure for supporting a first cassette in the dispenser, and the dispenser system further comprises a second adapter that is configured to be removably coupled to the mobile chassis to form a support structure for supporting a second cassette in the dispenser that is different from the first cassette, wherein the first adapter and the second adapter are arranged to be interchangeably coupled to the mobile chassis.

[0047] In another aspect, a dispenser assembly is provided, comprising a dispenser system as disclosed herein and a cartridge containing a fluid to be dispensed. In some embodiments, the cartridge further comprises a pump configured to dispense the fluid from the cartridge, the pump comprising a movable member (e.g., comprising a piston) configured to be supported by the support structure for movement with the mobile chassis.

[0048] In some embodiments, the cassette includes a pump having a movable member and a fixed member, the movable member and the fixed member being configured such that movement of the movable member relative to the fixed member produces a pumping action to dispense fluid from the cassette. The movable member is coupled to move with the mobile chassis by supporting the movable member of the cassette in a support structure, thereby enabling the pumping action of the cassette pump and dispensing fluid from the cassette.

[0049] In some embodiments, the box includes a fixed portion (e.g., a cylinder including a pump), wherein the dispenser system is configured to keep the fixed portion of the box from moving relative to the dispenser housing. In some embodiments, the dispenser itself keeps the fixed portion of the box from moving. For example, the box can include a box body positioned within a dispenser body, wherein the dispenser body itself (e.g., an outer wall of the dispenser body) prevents the box body from moving relative to the body.

[0050] In some embodiments, the fixed portion comprises a fixed portion of a pump of the cassette. In some embodiments, the dispenser system (e.g., a support structure) comprises a static component configured to hold the fixed portion of the cassette from moving relative to the dispenser body. In some embodiments, the static component is integral with the dispenser body.

[0051] In some embodiments, the box and the dispenser system (e.g., support structure) include complementary guide structures so that the box can only be loaded into the dispenser in a predetermined orientation. Thus, incorrect loading of the box into the dispenser housing is prevented or inhibited.

[0052] On the other hand, dispenser comprises the main body that limits dispenser inside, and this main body is configured to hold box, and described box holds fluid to be distributed.In addition, dispenser comprises the mobile chassis that is configured to move with respect to dispenser main body, is configured to be removably coupled to mobile chassis to form the first adapter of the supporting structure for supporting the first box in the dispenser and is configured to be removably coupled to mobile chassis to form the second adapter of the supporting structure for supporting the second box that is different from the first box in the dispenser.The first adapter and the second adapter are arranged to be interchangeably coupled to mobile chassis.For this reason, mobile chassis is arranged to cooperate interchangeably with the first adapter and the second adapter.The first adapter that is configured to operate together with the first box can be replaced with the second adapter that is configured to operate together with the first box, and does not need to replace whole mobile chassis or dispenser, and vice versa.

[0053] Each of the first and second adapters cooperates with the mobile chassis of the dispenser to form a corresponding support structure for supporting the corresponding type of box in the dispenser. Therefore, a dispenser with a single mobile chassis design can be adapted for use with a desired box type by using adapters. Thus, for a given range of boxes, for example, corresponding to a given range of fluid products, a single dispenser and mobile chassis design can be used and adapted to be compatible with a specific box via corresponding adapters. This makes manufacturing easier, more cost-effective, and less wasteful.

[0054] If desired, the dispenser system can be easily reconfigured to operate with different types of cartridges. For example, a first cartridge can contain a first fluid type, and a second cartridge can contain a second fluid type. This results in a simple, universal dispenser system that can be easily reconfigured to operate with different cartridges with minimal changes to the system, which is more cost-effective and reduces waste. Furthermore, the use of a first adapter and a second adapter ensures that only corresponding cartridges can be used with the dispenser, thereby ensuring that the quality, grade, and / or type of fluid dispensed is as desired.

[0055] In some embodiments, the first adapter includes a first retaining element for coupling the first adapter to the mobile chassis, and the second adapter includes a second retaining element for coupling the second adapter to the mobile chassis, wherein the mobile chassis includes corresponding retaining elements that correspond to the first retaining element of the first adapter and also to the second retaining element of the second adapter, such that the first retaining element and the second retaining element are arranged to interchangeably couple to corresponding retaining elements of the mobile chassis. To this end, the mobile chassis includes a single retaining element structure that corresponds to the first retaining element of the first adapter and the second retaining element of the second adapter, such that the mobile chassis is compatible with both the first and second adapters. In other words, only a single design of the mobile chassis is required that is compatible with both the first and second adapter retaining elements.

[0056] In some embodiments, the mobile chassis includes a cavity for receiving the first adapter and / or the second adapter, wherein the first adapter and the second adapter are arranged to be interchangeably positioned in the cavity. To this end, the cavity of the mobile chassis is configured to cooperate with both the first adapter and the second adapter, so that a single design of the mobile chassis can be used with both the first adapter and the second adapter.

[0057] In certain embodiments, the first adapter comprises a first locking element for engaging the counterpart of the first box, the second adapter comprises a second locking element for engaging the counterpart of the second box, and the first locking element of the first adapter and the second locking element of the second adapter are different. For this reason, the first adapter comprises a locking element configured to engage the first box, and the second adapter comprises a locking element configured to engage the second box. The locking elements of the first adapter and the second adapter are different so that they are configured to support different types of boxes. This allows the dispenser system to support different box types simply by changing the adapter that is coupled to the mobile chassis. This means that a single dispenser body and mobile chassis design can be used to accommodate a series of box types. Only corresponding adapters compatible with the type of required box are needed. Therefore, a universal dispenser system is provided, which reduces manufacturing requirements and also reduces the waste of cost and material.

[0058] In some embodiments, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 cartridge types can be included in a particular product range, for example, to correspond to different fluids. Therefore, a corresponding number of adapters can be provided. It should be understood that any number of cartridge types, configurations, or sizes can be included in a given product range, and corresponding adapters can be provided for each cartridge type. In some embodiments, different types of cartridges can include the same fluid but different fluid volumes.

[0059] In some embodiments, the dispenser system includes one or more additional adapters configured to be removably coupled to the mobile chassis to form a corresponding support structure for supporting a corresponding box, wherein the first adapter, the second adapter and the one or more additional adapters are arranged to be interchangeably coupled to the mobile chassis.

[0060] In another aspect, a dispenser assembly is provided that includes a dispenser system as disclosed herein, a first cartridge containing a fluid to be dispensed, and a second cartridge containing a fluid to be dispensed. In some embodiments, the first cartridge and the second cartridge each include a pump configured to dispense the fluid from the respective cartridge, the pump including a movable member (e.g., a piston) configured to be supported by a respective support structure for movement with the mobile chassis.

[0061] In some embodiments, the first and second cartridges each further comprise a fixed portion (e.g., a cylinder of a pump), wherein the dispenser system is configured to hold the fixed portion of the respective cartridges from moving relative to the dispenser housing. In some embodiments, the first and second cartridges and the dispenser system (e.g., corresponding support structures) comprise complementary guide structures such that the first and second cartridges can only be loaded into the dispenser in a predetermined orientation.

[0062] In some embodiments, the support structure for the respective cassettes is configured to support a first portion of the cassette for movement with the mobile chassis, and the dispenser system is configured to hold a second portion of the cassette from moving relative to the dispenser housing. In some embodiments, the first portion comprises a movable component coupled to a pump of the cassette. In some embodiments, the second portion comprises a main body of the cassette. In some embodiments, the second portion comprises a fixed portion of the pump.

[0063] In certain embodiments, described dispenser system comprises static components, and described static components is configured to keep said second portion of described box not to move relative to described dispenser housing, and wherein said mobile chassis is biased away from described static components.In certain embodiments, dispenser itself keeps the second portion of box not to move.For example, box can comprise the box body that is positioned in the dispenser main body, and wherein dispenser main body itself (for example, the outer wall of dispenser main body) prevents box body from moving relative to main body.

[0064] In some embodiments, the fixed portion comprises a fixed portion of a pump of the box. In some embodiments, the dispenser system (e.g., a support structure) comprises a static component configured to prevent the fixed portion of the box from moving relative to the dispenser body. In some embodiments, the static component is integrated with the dispenser body. Therefore, the total number of components required for manufacturing the dispenser system is kept to a minimum. In some embodiments, the mobile chassis is provided by a single component. Therefore, the total number of components required for manufacturing the dispenser system is kept to a minimum.

[0065] In some embodiments, the dispenser includes an actuator operably coupled to the mobile chassis such that, in use, fluid is dispensed from the dispenser upon actuation of the actuator. In some embodiments, the mobile chassis is configured to move in a first direction relative to the dispenser body, and the actuator is configured to move in a second direction different from the first direction.

[0066] For example, the actuator may be a button configured to actuate the mobile chassis to move upward when a user applies force. Alternatively, the actuator of the dispenser may be a sensor configuration, such as a proximity sensor, configured to actuate the dispenser once the user comes within a predetermined distance of the sensor. It will be appreciated that any suitable actuator may be used.

[0067] In another aspect, an assembly includes a cartridge containing a fluid to be dispensed and an adapter configured to be removably coupled to a dispenser to form a support structure for supporting the cartridge in the dispenser.

[0086] The present disclosure relates to a dispenser assembly for dispensing a fluid. The dispenser assembly includes a dispenser housing and a fluid cartridge. While embodiments of the present disclosure may take many different forms, several embodiments are discussed herein, and it should be understood that the present disclosure is to be considered exemplary and is not intended to limit the invention to the embodiments shown.

[0087] In addition, the fluid discussed herein can comprise the fluid of soap, shampoo, hand soap, lotion, detergent or other expectation.In addition, term " fluid " used herein is intended to comprise viscosity and non-viscous fluid, and pure concentrate, mixture, chemicals, naturally occurring fluid and any other fluid that can distribute.As used herein, term " soap " is intended to comprise any liquid detergent or the cleaning product that is suitable for distributing from fluid dispenser.Additive can be included in fluid and / or soap, for example spices, preservative, wetting agent, dyestuff and particle etc.

[0088] With reference to the accompanying drawings, Figure 1 and Figure 2 A dispenser assembly 100 is shown that includes a dispenser 110 for receiving a refill or cartridge 120. The dispenser 110 is configured to dispense a fluid. The fluid may include soap, shampoo, hand soap, lotion, cleanser, or other desired fluid.

[0089] like Figure 1 and Figure 2 As shown, the dispenser 110 is configured to receive and operably engage a cartridge 120 containing a fluid to be dispensed. In the illustrated embodiment, the cartridge 120 is a bottle-type container, but other types of cartridges are also within the scope of the present disclosure, such as bags, liners, rigid and non-rigid containers, and thin-walled and thick-walled containers.

[0090] like Figure 1 and Figure 2 As shown, the dispenser 110 includes a cover or front panel 130 and a body 140, which includes a sidewall 144 extending from a back panel 148 to at least partially define an interior cavity 152 of the dispenser 110. The body 140 includes a bottom end 156 opposite the top end 160, a front end 164 opposite the back end 168, and opposing side surfaces 172. In the illustrated embodiment, the front panel 130 is disposed at the front end 164, the back panel 148 is disposed at the back end 168, and the sidewall 144 extends between the front end 164 and the back end 168. In some embodiments, the sidewall 144 is configured to be translucent, and a transparent window 176 is disposed on the opposing side 172, but other configurations are possible.

[0091] In one example, the front panel 130 and the body 140 can be in an open position relative to each other (see Figure 2 ) and closed position (see Figure 1) move between, in the open position, the inner cavity 152 is exposed and / or uncovered, and in the closed position, the inner cavity 152 of the dispenser 110 is covered and / or hidden. In the closed position, the front panel 130 spans the front end 164 from the top 160 to the bottom 156. In addition, the side wall 144 of the body 140 extends continuously from the top 160 to the bottom 156 in a generally U-shape, and the opening 180 is located at the top 160, roughly centered between the front end 164 and the rear end 168 and between the opposite sides 172. In the illustrated embodiment, the back plate 148 and the side wall 144 are integrally formed into a single component. However, it should be understood that the back plate 148 and the side wall 144 can be provided as separate components, and in addition, the side wall 144 can be provided as a plurality of parts or sections coupled together.

[0092] refer to Figure 1 The front panel 130 and the body 140 are connected along the peripheral edge 192 formed at the periphery 188 of the front panel 130 and the side wall 144 (see Figure 2 ) are fitted together to form a tight fit therebetween. In some embodiments, a gasket (not shown) of elastomeric material or any other suitable material can be positioned between the front panel 130 and the body 140 to prevent the egress or ingress of liquids, gases, sound, or light emissions. The gasket can be carried by the front panel 130 and / or the body 140.

[0093] like Figure 1 and Figure 2 As shown, a locking or release mechanism 200 is disposed within the opening 180 at the top end 160 of the body 140 , and a latch or locking tongue 204 is carried by the front panel 130 . Figure 1 The release device 200 is shown in a first configuration, wherein the button wall 208 is exposed at the side wall 144 . Figure 2 The release device 200 is shown in a second configuration, wherein the key wall 212 is exposed at the side wall 144 for use with a unique key (not shown). The release device 200 and the locking tongue 204 together form at least a portion of a locking mechanism configured to releasably secure the front panel 130 to the body 140 in the closed position.

[0094] Continue to refer Figure 1 and Figure 2, the front panel 130 includes a front wall 220 that spans a perimeter 188. The perimeter 188 of the front panel 130 includes a peak 224 that is centrally located thereon and is located at its highest point opposite a notch 228 formed at the lower section 232. A trigger or actuator 236 is configured to be pivotally coupled to the front panel 130 and mounted within the notch 228, substantially flush with the front wall 220 and the perimeter 188 in the lower section 232. In the embodiment shown, the actuator 236 is coupled to the front panel 130 in the lower section 232 by an actuator hinge 240, a lever arm 242 (see Figure 2 ) protrude vertically upward and outward from the actuator hinge 240 to operably engage with the body 140, as will be further described in more detail below.

[0095] In the illustrated embodiment, the front panel 130 and the main body 140 can pivot or rotate about an access hinge 244 at the bottom end 156 of the main body 140 to expose and allow access to the interior cavity 152. The actuator hinge 240 is spaced apart from the bottom end 156, and therefore, the actuator hinge 240 is spaced apart from the access hinge 244 about which the main body 140 and the front panel 130 can pivot or rotate. Additionally or alternatively, the front panel 130 and the main body 140 can be completely detachable from each other without the use of hinges. In some embodiments, the front panel 130 can be adapted to slide relative to the main body 140 to expose or cover the interior cavity 152, or the front panel 130 can rotate in a direction different from that shown.

[0096] Figure 2 , an example of a cartridge 120 that can be loaded into the dispenser 110 is shown in . The cartridge 120 includes an opening (not shown) defined by a neck 246 through which the fluid exits the cartridge 120. The cartridge 120 can be formed as any suitable container, such as a bottle-type container, but other configurations are possible. The cartridge 120 also includes a pump 248 that is mounted within the opening (not shown) of the neck 246 and is configured to apply a suction force within the cartridge body 252 for pumping fluid from the cartridge body 252 and ultimately through the nozzle 256 to the hand of a user positioned below the dispenser 110. In addition, the pump 248 includes a housing flange 260 that is secured to and protrudes outwardly from the neck 246 of the cartridge 120. The cartridge 120 defines a central axis C that extends generally vertically and axially through the neck 246 and the cartridge body 252, as shown in FIG. Figure 2 In the illustrated embodiment, the nozzle 256 and pump 248 are axially aligned with the central axis C, but other configurations are possible.

[0097] Still refer to Figure 2, the support structure 264 of the dispenser 110 includes a collar 266 that is carried by the body 140 and is arranged to hold the housing flange 260 of the cartridge 120 against movement relative to the dispenser 110. The cartridge 120 and the support structure 264 include complementary guide structures that are arranged to allow the cartridge 120 to be loaded into the dispenser 110 in one or more predetermined orientations. In one embodiment, the neck 246 of the cartridge 120 is provided with a pair of flat portions 268, and the dispenser 110 includes a corresponding pair of guide protrusions 272. The flat portions 268 of the cartridge 120 and the corresponding guide protrusions 272 of the dispenser 110 cooperate to allow the cartridge 120 to be inserted into the dispenser 110 in one of two orientations. In the illustrated embodiment, the guide protrusions 272 are provided by the collar 266 of the body 140, but other configurations are possible.

[0098] Figure 3 and Figure 4 The cartridge 120 is shown received by the support structure 264 of the body 140 of the dispenser 110 as the cartridge 120 moves into the interior cavity 152 of the body 140. Figure 2 As shown by the direction arrow. Figure 4 As best shown in FIG, the housing flange 260 of the pump 248 is received within a corresponding pair of guide rails 276 formed by the collar 266 and positioned below the guide protrusions 272. When the cartridge 120 is received in any predetermined orientation, the housing flange 260 is arranged to slide within the guide rails 276 and prevent the cartridge 120 from vertically translating relative to the dispenser 110. As such, the housing flange 260 has a predetermined diameter D1 and thickness T1 corresponding to the dimensions of the guide rails 276 (see FIG. Figure 11 ). Additionally, the housing flange 260 is configured to abut the neck 246 of the cartridge 120 to form a seal therebetween, thereby preventing fluid or air from escaping.

[0099] Reference again Figure 2 , the pump 248 is provided with a pump housing (not shown) coupled within the neck 246 of the cartridge 120 and a valve 284 movable within the pump housing (not shown). In the illustrated embodiment, the valve 284 carries a drive flange 288 configured to move relative to the housing flange 260, and in particular, the drive flange 288 moves vertically and concentrically relative to the housing flange 260. The drive flange 288 has a predetermined diameter D2 and thickness T2 corresponding to the dimensions of the support structure 264 of the dispenser 110 (see Figure 11 ) to operate compatibly therewith, which will be described further below. However, it should be understood that any suitable pump configuration may be used to dispense fluid from the cartridge 120. Furthermore, the pump 248 may be configured as a foam-type, liquid-type, or any other suitable type of pump for dispensing a fluid product for consumption.

[0100] It should be understood that the cartridge 120 is intended to represent various types and versions that may be used with the dispenser 110. These types or versions of the cartridge 120 may differ in certain dimensions, namely, the diameter D1 and thickness T1 of the housing flange 260 or the diameter D2 and thickness T2 of the drive flange 288 (see FIG. Figure 11 ), which corresponds to a particular compatibility feature of the dispenser 110. Furthermore, the type or version of the cartridge 120 may vary with respect to the fluid contained therein, the type of pump 248 used, the material and / or construction of the cartridge body 252, or in other aspects.

[0101] exist Figures 2 to 4 and Figures 11 to 13 In the embodiment shown, the drive flange 288 and the housing flange 260 are generally circular, but other configurations are possible. For example, the drive flange 288 and / or the housing flange 260 can alternatively be provided in the form of a rectangular tab (not shown), or alternatively, the drive flange 288 and / or the housing flange 260 can be provided in a rectangular shape, or a triangular shape, or a trapezoidal shape, or an irregular shape, or any other suitable shape that can have dimensions corresponding to the support structure 264 of the dispenser assembly 100. In addition, the pump 248 can be removably coupled to the neck 246 of the cartridge 120 so as to be reusable with multiple cartridges 120, or alternatively, the pump 248 can be permanently or semi-permanently coupled to the neck 246 of the cartridge 120 and be used with one cartridge 120. In the embodiment shown, the pump 248 is coaxial with the central axis C and extends substantially vertically through and outwardly from the neck 246 of the cartridge 120, but other arrangements are possible. For example, the valve 284 and the drive flange 288 may extend outwardly from the neck 246 of the cartridge 120 at an angle relative to the central axis C.

[0102] refer to Figure 3 and Figure 4 , support structure 264 also includes a drive unit 292, which has a mobile chassis 296, and the mobile chassis 296 is arranged to translate vertically within the inner cavity 152. In addition, the drive unit 292 includes an adapter 300, which is configured to be removably received in the mobile chassis 296, so that the mobile chassis 296 and the adapter 300 are configured together to receive and operably engage the predetermined box type in the dispenser 110. In one example, the mobile chassis 296 is provided as a separate component of the dispenser 110, and the collar 266 is integral with the dispenser 110, but other configurations are also possible. The adapter 300 is configured to have a size corresponding to the drive flange 288 to achieve compatible operation therewith, as will be further described below.

[0103] Still refer to Figure 3 and Figure 4, the mobile chassis 296 of the drive unit 292 defines a receiving portion 304 configured to receive an operable component of the cartridge 120, such as the drive flange 288, wherein the operable component corresponds to the type of cartridge. In the illustrated embodiment, the receiving portion 304 is configured to receive the drive flange 288 carried by and operably connected to the pump 248 of the cartridge 120 to dispense fluid. Figure 2 As shown, the drive unit 292 defines a drive axis A that is centrally located in the receiving portion 304 and extends vertically through the body 140 of the dispenser 110. When the cartridge 120 is positioned in the dispenser 110, the drive flange 288 of the cartridge 120 occupies the receiving portion 304 of the support structure 264, and thus, the drive axis A of the dispenser 110 is coaxial with the central axis C of the cartridge 120, as shown in FIG. Figure 3 Furthermore, the mobile chassis 296 is configured to translate in a vertical direction (ie, along the drive axis A) relative to the collar 266, such as by actuating the dispenser 110 to dispense fluid.

[0104] refer to Figure 5 and Figure 6 , the adapter 300 includes a joint or center portion 308 that connects a first leg 312 to a second leg 316, both of which extend outward from opposite sides of the center portion 308. In the illustrated embodiment, the adapter 300 is symmetrical about a longitudinal axis S that is centrally disposed between the first leg 312 and the second leg 316 and intersects the center portion 308. However, in other embodiments, the adapter 300 may be asymmetrical or may be symmetrical about a different axis. The first leg 312 and the second leg 316 are capable of rotating about the center portion 308, thereby causing the center portion 308 to bend or flex. In some embodiments, the first leg 312 and the second leg 316 also bend or flex when rotated about the center portion 308. As Figure 5 As shown, a central flexure axis F is defined by the central portion 308 and extends vertically perpendicular to the longitudinal axis S. Each of the first leg 312 and the second leg 316 is configured to displace (e.g., rotate) about the central flexure axis F. In one example, each of the first leg 312 and the second leg 316 rotates inwardly (i.e., toward each other) and outwardly (i.e., away from each other) about the flexure axis F, as indicated by the bidirectional arrows.

[0105] refer to Figure 5First leg 312 includes a first latch 324 at a first distal end 328 opposite central portion 308, and second leg 316 includes a second latch 332 at a second distal end 336 opposite central portion 308. First latch 324 and second latch 332 are configured to retain adapter 300 within mobile chassis 296. First latch 324 and second latch 332 may be individually referred to as retention protrusions or elements, and collectively referred to as a first pair of retention protrusions or elements. Each of first latch 324 and second latch 332 is generally triangular in shape and extends from a first curved arm 340 and a second curved arm 344, respectively, connected to the respective first distal end 328 and second distal end 336 of first leg 312 and second leg 316. Furthermore, first and second distal ends 328 and 336 of adapter 300 are also configured as curved portions. The first latch 324 projects laterally outward (i.e., away from the longitudinal axis S) from the first flexure arm 340, and a first slot 348 is defined between the first latch 324 and the first flexure arm 340. Similarly, the second latch 332 projects laterally outward (i.e., away from the longitudinal axis S) from the second flexure arm 344, and a second slot 352 is defined between the second latch 332 and the second flexure arm 344.

[0106] Still refer to Figure 5 A first rib 356 extends laterally inward (i.e., toward the longitudinal axis S) from the first latch 324 toward the first leg 312 to prevent excessive displacement (e.g., rotation) of the first latch 324. Similarly, a second rib 360 extends laterally inward (i.e., toward the longitudinal axis S) from the second latch 332 toward the second leg 316 to prevent excessive displacement (e.g., rotation) of the second latch 332. Furthermore, a first tab 364 extends longitudinally outward (i.e., parallel to the longitudinal axis S) from the first flexure arm 340, and a second tab 370 extends longitudinally outward (i.e., parallel to the longitudinal axis S) from the second flexure arm 344 to provide a surface for bidirectional manipulation, such as by a user's finger and / or thumb. In some embodiments, the range of rotation about the first distal flexure axis F1 and the range of rotation about the second distal flexure axis F2 are equal. However, the range of rotation about the central flexure axis F is greater than the range of rotation of the first distal flexure axis F1 and the second distal flexure axis F2.

[0107] It should be understood that the first latch 324 and the second latch 332 are configured to shift relative to the central portion 308 by translating and rotating (e.g., bending or flexing) about the central flexure axis F. In addition, the first latch 324 is capable of shifting (e.g., rotating) about a first distal flexure axis F1 defined between the first flexure arm 340 and the first distal end 328 and extending vertically perpendicular to the longitudinal axis S. Similarly, the second latch 332 is capable of shifting (e.g., rotating) about a second distal flexure axis F2 defined between the second flexure arm 344 and the second distal end 336 and extending vertically perpendicular to the longitudinal axis S. Figure 5 and Figure 8 As shown, the first latch 324 and the second latch 332 are equidistantly spaced from the center portion 308, but other configurations are possible. In addition, the first latch 324 and the second latch 332 are spaced apart from each other by a distance W that is greater than the distance that the first latch 324 or the second latch 332 is spaced apart from the center portion 308.

[0108] In the illustrated embodiment, the first latch 324 and the second latch 332 are respectively displaceable inwardly (i.e., toward each other) and outwardly (i.e., away from each other) about the central flexure axis F by displacement (e.g., rotation) of the first leg 312 and the second leg 316. Furthermore, the first latch 324 is rotatable inwardly (i.e., toward the longitudinal axis S) and outwardly (i.e., away from the longitudinal axis S) about the first distal flexure axis F1. Furthermore, the second latch 332 is also rotatable inwardly (i.e., toward the longitudinal axis S) and outwardly (i.e., away from the longitudinal axis S) about the second distal flexure axis F2. Thus, displacement of the first latch 324 can occur due to its dependence on the first leg 312, such that when the first leg 312 is displaced about the central flexure axis F and / or the central portion 308, the first latch 324 is also displaced. Thus, the position of the first latch 324 is a function of the position of the first leg 312 relative to the longitudinal axis S and / or the second leg 316. Furthermore, displacement of the second latch 332 can occur due to its dependence on the second leg 316, such that as the second leg 316 displaces about the central flexure axis F and / or the central portion 308, the second latch 332 also displaces. Thus, the position of the second latch 332 is a function of the position of the second leg 316 relative to the longitudinal axis S and / or the first leg 312. Furthermore, the distance W between the first latch 324 and the second latch 332 is a function of the position of the first and second legs 312, 316 relative to the central portion 308 and the central flexure axis F, such that rotation can increase or decrease the distance W between the first latch 324 and the second latch 332. Similarly, rotation of the first latch 324 about the first flexure arm 340 and the first distal flexure axis F1, and rotation of the second latch 332 about the second flexure arm 344 and the second distal flexure axis F2, can increase or decrease the distance between the first latch 324 and the second latch 332.

[0109] Additionally, the first latch 324 is displaceable independently of the first leg 312 and independently of the central flexure axis F. That is, independent displacement of the first latch 324 can occur about the first distal flexure axis F1 without affecting the positions of the first leg 312 and the second leg 316. Additionally, the second latch 332 is displaceable independently of the second leg 316 and independently of the central flexure axis F. That is, independent displacement of the second latch 332 can occur about the second distal flexure axis F2 without affecting the positions of the second leg 316 and the first leg 312. It should also be understood that the first latch 324 and the second latch 332 can be displaced independently of each other about the first distal flexure axis F1 and the second distal flexure axis F2, respectively.

[0110] exist Figure 5In the illustrated embodiment, the first latch 324 and the second latch 332 are positioned rearward of the first flexure arm 340 and the second flexure arm 344, while the first leg 312, including the first latch 324, and the second leg 316, including the second latch 332, are positioned forward of the central portion 308. Furthermore, the first flexure arm 340 and the second flexure arm 344 each curve in a rearward direction opposite the forward direction of curvature of the central portion 308. Due to these relative positions and curvatures, clockwise and counterclockwise rotation of the first latch 324 about the first flexure arm 340 (i.e., the first distal flexure axis F1) results in displacement in directions opposite to the central portion 308 (i.e., the central flexure axis F). Similarly, clockwise and counterclockwise rotation of the second latch 332 about the second flexure arm 344 (i.e., the second distal flexure axis F2) results in displacement in directions opposite to the central portion 308 (i.e., the central flexure axis F). For example, clockwise rotation of the first latch 324 about the first distal flexure axis F1 causes laterally inward displacement of the first latch 324, but clockwise rotation of the first latch 324 about the central portion 308 and / or the central flexure axis F by means of the first leg 312 causes laterally outward displacement of the first latch 324. In a similar manner, clockwise rotation of the second latch 332 about the second distal flexure axis F2 causes laterally outward displacement of the second latch 332, but clockwise rotation of the second latch 332 about the central flexure axis F by means of the first leg 312 causes laterally inward displacement of the first latch 324. It should be understood that the counterclockwise rotation of the first latch 324 relative to the center portion 308 and / or the center flexure axis F and the first flexure arm 340 and / or the first distal flexure axis F1 and the counterclockwise rotation of the second latch 332 relative to the center portion 308 and / or the center flexure axis F and the second flexure arm 344 and / or the second distal flexure axis F2 are also opposite.

[0111] Figure 5The adapter 300 is depicted in its rest position. Due to the arcuate or curved shape of the central portion 308, as well as its material, thickness, and dimensions, the central portion 308 defines a central biasing region 374 that imparts resistance to displacement (e.g., rotation) of each of the first and second legs 312, 316 from the rest position, thereby causing springback when displaced in any direction therefrom. Thus, whether rotating laterally inward or outward, each of the first and second legs 312, 316 must overcome this resistance in order to displace (e.g., rotate) about the central flexure axis F. In this manner, each of the first and second legs 312, 316 is configured to spring back or snap back from a displaced position to the rest position by the central portion 308, and in particular, by the resistance applied to each of the first and second legs 312, 316 from the central biasing region 374 of the central portion 308. Furthermore, the central offset region 374 is configured to allow the first latch 324 and the second latch 332 (ie, the first pair of protrusions) to move relative to each other via the first leg 312 and the second leg 316 .

[0112] In addition, a first distal biasing region 378 is formed by the first flexure arm 340 and the first distal end 328 by the arcuate or curved shape of the first flexure arm 340 and the first distal end 328 as well as the material, thickness and size thereof. The first distal biasing region 378 intersects the first distal flexure axis F1 and imparts resistance against displacement (e.g., rotation) of the first latch 324 from a rest position about the first distal flexure axis F1, thereby causing rebound to occur when displaced in any direction therefrom. Therefore, this resistance must be overcome in order for the first latch 324 to be displaced (e.g., rotated) about the first distal flexure axis F1, whether laterally inwardly or laterally outwardly. Therefore, the first latch 324 is configured to rebound or snap back to the rest position from the displaced position by the first flexure arm 340 and, in particular, by the resistance applied to the first latch 324 from the first distal biasing region 378 of the first flexure arm 340 during displacement. As shown in FIG. Figure 5 As will be appreciated, the first distal offset region 378 is connected to the central offset region 374 via the first leg 312 and can be displaced (e.g., rotated) about the central flexure axis F via the first leg 312. In this manner, the first distal offset region 378, including the first distal flexure axis F1, can be rotated about the central flexure axis F and / or the central offset region 374.

[0113] In a similar manner, a second distal biasing region 382 is formed by the second flexure arm 344 and the second distal end 336 by the arcuate or curved shape of the second flexure arm 344 and the second distal end 336 and by their materials, thicknesses, and dimensions. The second distal biasing region 382 intersects the second distal flexure axis F2 and applies a resistance force against displacement (e.g., rotation) of the second latch 332 from the rest position, thereby causing rebound to occur when displaced in any direction therefrom. Thus, this resistance force must be overcome in order for the second latch 332 to be displaced (e.g., rotated) about the second distal flexure axis F2, whether laterally inwardly or laterally outwardly. Thus, the second latch 332 is configured to rebound or snap back from the displaced position back to the rest position by the second flexure arm 344 and, specifically, by the resistance force applied to the second latch 332 from the second distal biasing region 382 of the second flexure arm 344 during displacement. As shown from Figure 5 As will be appreciated, the second distal offset region 382 is connected to the central offset region 374 via the second leg 316 and can be displaced (e.g., rotated) about the central flexure axis F via the second leg 316. In this manner, the second distal offset region 382, ​​including the second distal flexure axis F2, can be rotated about the central flexure axis F and / or the central offset region 374.

[0114] It is contemplated that the central bias region 374 imparts a first resistance that is different from the second resistance imparted by the first distal bias region 378 and the third resistance imparted by the second distal bias region 382, ​​or alternatively, the central bias region 374 may impart a resistance equal in magnitude to the resistance imparted by the first distal bias region 378 and / or the second distal bias region 382. It is also contemplated that the first distal bias region 378 and the second distal bias region 382 impart equal resistances, but in some cases, the second resistance of the first bias region 378 is different from the third resistance of the second distal bias region 382 without departing from the scope of the present disclosure. Furthermore, the first rotational range permitted by the central bias region 374 may be greater than the second rotational range permitted by the first distal bias region 378 and the third rotational range permitted by the second distal bias region 382. In some embodiments, the rotational range is proportional to the resistance, such that a greater resistance results in a lower rotational range. In this manner, different resistances may be associated with different rotational ranges.

[0115] Still refer to Figure 5, the adapter 300 defines a height H0 that varies along the same. In one example, the height H0 is the same along the first leg 312 and the second leg 316, but is smaller at the center portion 308. In particular, the reduced height H0 of the adapter 300 at the center portion 308 is provided for engagement with a locator 386 that extends from the mobile chassis 296 into a recess 390 that is configured to receive the center portion 308, as shown. Figure 8 As shown. Figure 5 In the illustrated embodiment, the first leg 312 and the second leg 316 each include a plurality of protrusions 396 extending therefrom, and the protrusions 396 may be spaced apart from one another and positioned along one or more surfaces of the first leg 312 and the second leg 316, respectively. In the illustrated embodiment, the plurality of protrusions 396 are provided on a top surface 400 and a bottom surface (not shown) of each of the first leg 312 and the second leg 316, although other configurations are possible.

[0116] Continue to refer Figure 5 , the adapter 300 includes a first latch 404 disposed on the first leg 312 and a second latch 408 disposed on the second leg 316 for retaining the drive flange 288. The first latch 404 and the second latch 408 may be individually referred to as retention protrusions or elements and collectively referred to as a second pair of retention protrusions or elements. Furthermore, it should be understood that the first leg 312 includes the first latch 324 and the first latch 404, also referred to as a first set of retention protrusions or elements, and the second leg 316 includes the second latch 332 and the second latch 408, also referred to as a second set of retention protrusions or elements. In the illustrated embodiment, the first latch 404 and the second latch 408 are equidistantly spaced from the center portion 308 and are located between the center portion 308 and the first distal ends 328 and the second distal ends 336 of the first leg 312 and the second leg 316, respectively. Reference Figure 5 In the adapter 300, the first lock 404 and the second lock 408 each extend laterally inwardly toward each other to define a predetermined dimension or distance E1, which is the retention width. In one example, the first lock 404 includes a first slope 412 extending to a first tip 416, and a first channel 420 is defined below the first lock 404 between the first leg 312 and the first tip 416. Similarly, the second lock 408 includes a second slope 424 extending to a second tip 428 and a second channel 432 defined below the second lock 408 between the second leg 316 and the second tip 428 (see FIG. Figure 7 ). The first ramp 412 and the second ramp 424 each extend downwardly and laterally inwardly from the top surface 400 of the adapter 300 to a first tip 416 and a second tip 428, respectively. In addition, the first lock 404 and the second lock 408 are arranged on the adapter 300 to define a channel height EE1 (see Figure 11 ), the channel height EE1 is less than the height H0 of the adapter 300.

[0117] about Figure 5 Adapter 300, the predetermined distance E1 is measured between the first leg 312 in the first channel 420 of the first latch 404 and the second leg 316 in the second channel 432 of the second latch 408 (see Figure 11 In this way, the adapter 300 is configured to have a predetermined size, namely, the distance E1 (see Figure 11 ) to be compatible with one or more predetermined cartridge types such that cartridge types compatible with the dispenser assembly 100 and the adapter 300 will have dimensions corresponding to the predetermined distance E1, and incompatible cartridges will not have dimensions corresponding to the predetermined distance E1. In the illustrated embodiment, the predetermined distance E1 is provided to correspond to the diameter D2 of the drive flange 288 of the cartridge 120 (e.g., Figure 11 , 432 ). The adapter 300 is configured to be compatible with the first leg 312 and first latch 404, and the second leg 316 and second latch 408. The adapter 300 is configured to be compatible with the first leg 312 and first latch 404, and the second leg 316 and second latch 408. The adapter 300 is configured to be compatible with the first leg 312 and first latch 404, and the second leg 316 and second latch 408. The adapter 300 is configured to be compatible with the first leg 312 and first latch 404, and the second leg 316 and second latch 408. The adapter 300 is configured to be compatible with the first leg 312 and first latch 404, and the second leg 316 and second latch 408. The adapter 300 can be configured to have different shapes and sizes to define a larger or smaller channel height EE1, or multiple channel heights. Furthermore, the drive flange 288 can be configured to have different sizes and shapes to define multiple thicknesses T2 and / or multiple diameters D2 to correspond to the adapter 300. Thus, the adapter 300 and the drive flange 288 may be provided in a variety of configurations (ie, shapes and sizes) to achieve operable engagement with one another.

[0118] refer to Figure 6, the movable chassis 296 includes a slot 436 for receiving the adapter 300, as indicated by the directional arrows. In the illustrated embodiment, the slot 436 is defined between an upper member 440 and a lower member 444 opposite the upper member 440, the lower member 444 defining a lower surface 448 and a recessed edge 452 extending around the receiving portion 304. In one example, the upper member 440 and the lower member 444 are generally U-shaped, but other configurations are possible. The upper member 440 has a lip 456 that extends around the receiving portion 304 and varies in height as the lip 456 protrudes vertically upward from the upper member 440. In addition, the movable chassis 296 has a front end 458 that is arranged to be adjacent to the front panel 130 (see FIG. 1 ) when the dispenser assembly 100 is in the closed position. Figure 14 ).

[0119] Additionally, the mobile chassis 296 has a rear end 464 that includes spring posts 468, each of which is configured to receive a spring 472 (see FIG. Figure 14 ).like Figure 6 As shown, the spring posts 468 are each a generally tapered structure that becomes narrower as they extend vertically upward from a spring seat 476 that is partially surrounded by a curved boundary 480. In addition, the rear end 464 of the mobile chassis 296 includes a shaft 484 formed by a pair of shaft walls 488 that are L-shaped and extend from the center member 492, with a gap 496 extending between the pair of shaft walls 488. The shaft 484 is configured to be coupled to a track (not shown) of the body 140 for translation, e.g., sliding, therewith, although other configurations are possible.

[0120] refer to Figure 6 and Figure 7 , the mobile chassis 296 also includes a pair of actuation docking portions 500, each actuation docking portion 500 having opposing inner and outer walls 504, 508. An angled docking wall 512 extends from an upper end 516 spanning between the inner and outer walls 504, 508. In addition, an arcuate bracket 520 extends between the inner and outer walls 504, 508 below the upper end 516. In the illustrated embodiment, the angled docking wall 512 extends vertically upward and forward relative to the upper end 516 of the actuation docking portion 500, and the actuation surface 524 (see Figure 7 ) extends continuously from the angled docking wall 512 to the upper end 516. The actuation dock 500 is configured to receive the lever arm 242 of the actuator 236 (see Figure 14), so that when the front panel 130 is pivoted toward the main body 140 about the main body hinge (not shown), the lever arm 242 contacts the actuation surface 524 of the angled docking wall 512. Furthermore, when the front panel 130 is further pivoted to the closed position, the lever arm 242 slides from the angled docking wall 512 to the upper end 516 of the actuation dock 500 while maintaining contact with the actuation surface 524. In this manner, the lever arm 242 is positioned to operably engage with the mobile chassis 296.

[0121] like Figure 7 and Figure 8 As shown, the adapter 300 is configured to be received by the mobile chassis 296 to form the drive unit 292 of the support structure 264. The height H0 of the adapter 300 (see Figure 5 ) corresponds to the height of the slot 436 for receiving the adapter 300 therein without excessive friction, such as in a clearance fit. In addition, the central portion 308 and a portion of the first leg 312 and the second leg 316 are received in the groove wall 528 at the rear end 464 of the mobile chassis 296 (see Figure 8 ) in the groove 390 formed by the adapter 300, wherein the reduced height H0 of the adapter 300 at the central portion 308 corresponds to the locator 386 to prevent an unauthorized or incorrect adapter from being operably received in the narrow slot 436 and also ensure the correct installation of the adapter 300.

[0122] refer to Figure 8 , the first latch 404 and the second latch 408 are positioned opposite each other relative to the receiving portion 304 and equidistant from the central flexure axis F of the central portion 308. Due to the arcuate shape of the first leg 312 and the second leg 316, the adapter 300 partially surrounds the receiving portion 304 of the mobile chassis 296 while allowing space within the slot 436 for each of the first leg 312 and the second leg 316 to be displaced laterally outward about the central flexure axis F.

[0123] As in Figure 8As best seen in the cross-sectional view of FIG, the first latch 324 is received within a first aperture 532 defined between a first bumper 536 and a first side 540 of the moving chassis 296. Similarly, the second latch 332 is received within a second aperture 544 defined between a second bumper 548 and a second side 552 of the moving chassis 296. To effectuate insertion of the adapter 300 into the slot 436, the first latch 324 and the second latch 332 slide along the first side 540 and the second side 552, respectively, at the front end 458 of the moving chassis 296, which causes the first latch 324 and the second latch 332 to displace laterally inward. Upon reaching the first aperture 532 and the second aperture 544, the first latch 324 and the second latch 332 snap back into the rest position due to the resistance exerted by the first distal biasing region 378 and the second distal biasing region 382, ​​such that the first latch 324 extends into the first aperture 532 and the second latch 332 extends into the second aperture 544. In this manner, the adapter 300 is coupled to the mobile chassis 296.

[0124] exist Figure 8 In the illustrated embodiment, when the adapter 300 is received within the slot 436 and coupled to the moving chassis 296 prior to engagement with the drive flange 288, the first slot 348 is spaced from the first side 540 of the moving chassis 296, and the second slot 352 is spaced from the second side 552 of the moving chassis 296. Furthermore, due to the shape and size of the adapter 300, spacing is provided between the first bumper 536 and the first latch 324, and between the second bumper 548 and the second latch 332. Furthermore, spacing exists between the first leg 312 and the adjacent groove wall 528, and between the second leg 316 and the adjacent groove wall 528, enabling lateral outward displacement (e.g., rotation) about the central flexure axis F when the adapter 300 is received within the slot 436 and coupled to the moving chassis 296. In this manner, the adapter 300 is configured to flex within the slot 436 of the moving chassis 296 while coupled to the moving chassis 296.

[0125] Additionally, the adapter 300 is configured to be removed from the slot 436 by displacing the first leg 312 and the second leg 316. This is accomplished by the user squeezing the tabs 364, 370 together to displace the first leg 312 and the second leg 316 laterally inward (e.g., toward each other), which displaces the first latch 324 and the second latch 332 from the first hole 532 and the second hole 544, respectively. The user then removes the adapter 300 from the slot 436 of the mobile chassis 296 and releases the tabs 364, 370, thereby allowing the first leg 312 and the second leg 316 to spring back to a rest position.

[0126] like Figure 7 and Figure 8As shown, when operably received in the slot 436 of the moving chassis 296, the drive axis A is generally centrally positioned within the receiving portion 304 and is generally centrally disposed between the central flexure axis F and the first and second distal flexure axes F1, F2 of the adapter 300. In the illustrated embodiment, the central flexure axis F and the first and second distal flexure axes F1, F2 are both parallel to the drive axis A, such that displacement (e.g., rotation) occurs about these vertical axes. Thus, the adapter 300 is configured to translate vertically through its position within the slot 436 of the moving chassis 296 while being configured to flex about the central flexure axis F, as described below with respect to FIG. Figure 11-13 As stated.

[0127] Figure 9 Another embodiment of an adapter 600 is shown that is configured to be received within the slot 436 of the mobile chassis 296 for use with a compatible cartridge 120, as described with respect to FIG. Figure 6-8 Adapter 300 is shown in FIG. Figure 9 , Adapter 600 with Figures 5 to 8Adapter 600 is substantially identical to adapter 300 of the first embodiment, except that adapter 600 is configured to be compatible with a different cartridge than the cartridge of adapter 300 of the first embodiment. Specifically, adapter 600 includes a first locking catch 604 that extends laterally inwardly further than first locking catch 404 of the first embodiment of adapter 300, and a second locking catch 608 that extends laterally inwardly further than second locking catch 408 of the first embodiment of adapter 300. Furthermore, first locking catch 604 includes a first ramp 612 that extends downwardly and laterally inwardly toward a first tip 616, and second locking catch 608 includes a second ramp 620 that extends downwardly and laterally inwardly toward a second tip 624. Furthermore, the first latch 604 includes a first base member 628 that extends laterally inward from the first leg 312 approximately halfway (1 / 2) between the first leg 312 and the first tip 616, and the second latch 608 includes a second base member 632 that extends laterally inward from the second leg 316 approximately halfway (1 / 2) between the second leg 316 and the second tip 624. A predetermined distance E2, serving as a retention width, is defined between the first base 628 of the first latch 604 and the second base 632 of the second latch 608. Furthermore, a cavity 640 is formed adjacent to each of the first and second latches 604, 608 of the adapter 600, such that the first and second latches 604, 608 are substantially hollow. Furthermore, a first rib 644 extends inward from the first leg 312 at an angle relative to the longitudinal axis S, and a second rib 648 extends inward from the second leg 316 at an angle relative to the longitudinal axis S. The first and second ribs 644, 648 are configured to abut the drive flange 288 of the cartridge 120, which is sized and shaped to be compatible with the adapter 600. In particular, the diameter D2 of the drive flange 288 corresponds to a predetermined distance E2 for compatible operation with the adapter 600. In this manner, the first and second ribs 644, 648 allow the drive flange 288 to be more easily captured between the first and second latches 604, 608, while also preventing tilting or rotation relative to the adapter 600.

[0128] Figure 10 Yet another embodiment of an adapter 700 is shown that is configured to be received within the slot 436 of the mobile chassis 296 for use with a compatible cartridge type. Figure 5-8 Adapter 300 and Figure 9Adapter 600 is substantially identical to the adapter 700 of the first embodiment, except that adapter 700 is configured to be compatible with different cartridges than both the first embodiment adapter 300 and the second embodiment adapter 600. Specifically, adapter 700 includes a first latch 704 and a second latch 708, the first latch 704 extending laterally inwardly further than the first element 604 of the second embodiment adapter 600, and the second latch 708 extending laterally inwardly further than the second latch 608 of the second embodiment adapter 600. Furthermore, the first latch 704 includes a first ramp 712 extending downwardly and laterally inwardly toward a first tip 716, and the second latch 708 includes a second ramp 720 extending downwardly and laterally inwardly toward a second tip 724. Furthermore, the first latch 704 includes a first base member 728 that extends approximately two-thirds (2 / 3) of the way inward from the first leg 312 between the first leg 312 and the first tip 716 to form a first channel 730 therebetween, and the second latch includes a second base member 732 that extends approximately two-thirds (2 / 3) of the way inward from the second leg 316 between the second tip 724 and the second leg 316 to form a second channel 734 therebetween. A predetermined distance E3 is defined between the first base member 728 of the first latch 704 and the second base member 732 of the second latch 708, which is the retention width. Furthermore, a cavity 740 is formed adjacent each of the first latch 704 and the second latch 708 of the adapter 700, such that the first latch 704 and the second latch 708 are substantially hollow. In addition, a first rib 744 extends inwardly from the first leg 312 at an angle relative to the longitudinal axis S, and a second rib 748 extends inwardly from the second leg 316 at an angle relative to the longitudinal axis S. The first rib 744 and the second rib 748 are configured to abut the drive flange 288 of another cartridge 120 that is compatible with the adapter 700. In particular, the diameter D2 of the drive flange 288 corresponds to a predetermined distance E3 for compatible operation with the adapter 700. In this manner, the first rib 744 and the second rib 748 allow the drive flange 288 to be more easily captured between the first latch 704 and the second latch 708, while also preventing tilting or rotation relative to the adapter 700.

[0129] As from Figure 5 、 Figure 9 and Figure 10As will be appreciated, the predetermined distance E2 is greater than the predetermined distance E3 and less than the predetermined distance E1. The predetermined distances E1, E2, and E3 of the adapters 300, 600, and 700, respectively, can be in the range of approximately 0.3 inches (7.62 mm) to approximately 2 inches (50.8 mm), although other configurations are possible. In one example, the predetermined distance E1 is approximately 1 inch (25.4 mm), the predetermined distance E2 is approximately 0.85 inches (21.59 mm), and the predetermined distance E3 is approximately 0.7 inches (17.78 mm), although other configurations are possible. It is contemplated that the diameter D2 of the drive flange 288 can be in the range of approximately 0.3 inches (7.62 mm) to approximately 2 inches (50.8 mm), and preferably in the range of approximately 0.7 inches (17.78 mm) to approximately 1 inch (25.4 mm).

[0130] like Figures 11 to 13 As shown, when the drive flange 288 is compatible with the adapter 300 present in the slot 436 of the mobile chassis 296 so that the predetermined distance E1 corresponds to the diameter D2, the drive flange 288 is configured to slide on each of the first lock 404 and the second lock 408 to be captured in the first channel 420 and the second channel 432 and fixed to the mobile chassis 296. In addition, when the drive flange 288 slides on each of the first lock 404 and the second lock 408, each of the first leg 312 and the second leg 316 flexes about the central flexure axis F and resists the central offset area 374 (see FIG. 2 ) of the central portion 308. Figure 5 ) and any additional resistance provided by the material, thickness, size, and curvature of the arcuate shape of each of the first leg 312 and the second leg 316 to outward displacement (e.g., rotation).

[0131] refer to Figure 11 , with the cartridge 120 mounted in an inverted orientation within the support structure 264 of the body 140 within the dispenser 110, the housing flange 260 is received within the guide track 276 of the collar 266, and the flat portion 268 of the neck 246 is received by the guide protrusion 272 of the collar 266. In this mounted position, the central axis C of the cartridge 120 is aligned with the drive axis A of the drive unit 292, such that the drive flange 288 of the pump 248 is coaxial with the drive axis A. However, as Figure 11 As shown, the pump 248 is in a pre-primed state with the valve 284 fully retracted into the pump housing (not shown). Thus, the drive flange 288 is vertically spaced from the adapter 300 and the receiving portion 304, and more specifically, the drive flange 288 is positioned above the adapter 300 and below the collar 266. Figure 11The housing flange 260 is shown as having a thickness T1 and a diameter D1, the drive flange 288 as having a thickness T2 and a diameter D2, and the adapter 300 as having a predetermined distance E1 that is substantially equal to or substantially equivalent to the diameter D2 of the drive flange 288. Thus, the adapter 300 and drive flange 288 are shown as being compatible. If the drive flange 288 had a smaller diameter D2 and was therefore incompatible, the first and second latches 404, 408 of the adapter 300 would pass over the drive flange 288 without contact, rendering the drive flange 288 inoperable with the drive unit 292. Alternatively, if the drive flange 288 had a larger diameter D2 and was therefore incompatible, the first and second latches 404, 408 would not translate over the drive flange 288 and sliding engagement would not occur, i.e., the drive unit 292 would become stuck. In the illustrated embodiment, because the valve 284 is fully retracted into the pump housing (not shown) of the cassette 120 , the valve 284 , and therefore the drive flange 288 , is prevented from translating vertically upward.

[0132] Figure 12 The capture stage of the dispenser assembly 100 is shown wherein the actuator 236 has been depressed in a substantially longitudinal direction (e.g., rearward) to rotate about the actuator hinge 240 of the front panel 130 for applying a vertically upward force on the drive unit 292 via the lever arm 242. In the illustrated embodiment, the drive unit 292 (i.e., the mobile chassis 296 and the adapter 300) translates vertically upward to capture the drive flange 288 between the first and second legs 312, 316 of the adapter 300 and between the first and second latches 404, 408. Additionally, the drive flange 288 is captured within the first and second channels 420, 432 of the adapter 300 such that it is secured between the first latch 404 and the mobile chassis 296 and between the second latch 408 and the mobile chassis 296. Figure 12 At this stage, the adapter 300 has been vertically translated, i.e., lifted, so that the drive flange 288 slides along the first ramp 412 and the second ramp 424, which causes the first leg 312 and the second leg 316 to be displaced (e.g., rotated) about the central axis F. After the first tip 416 and the second tip 428 of the adapter 300 are lifted above the drive flange 288, the central offset region 374 of the central portion 308 (at Figure 12 Hidden in but Figure 5266) snaps the first and second legs 312, 316 back into the rest position, thereby capturing the drive flange 288 laterally between the first and second latches 404, 408 and vertically between the adapter 300 and the mobile chassis 296. Because the cartridge 120 is secured against vertical translation by being mounted within the collar 266, and because the valve 284 is secured against vertical translation by being fully retracted within the pump housing (not shown) at this stage, the drive flange 288 does not translate vertically when the adapter 300 passes over the drive flange 288 due to manual operation of the actuator 236. In this manner, the drive flange 288 of the pump 248 is captured by the drive unit 292.

[0133] refer to Figure 13 , the drive unit 292 has translated vertically downward back to the initial position wherein the drive flange 288 is captured between the adapter 300 and the mobile chassis 296. In this initial position, the first leg 312 and the second leg 316 of the adapter 300 are each simultaneously coupled to the mobile chassis 296, for example, by the first latch 324 and the second latch 336, and to the drive flange 288, for example, by the first catch 404 and the second catch 408. The downward vertical translation is caused by the force exerted by the spring 472 between the collar 266 and the mobile chassis 296 such that the mobile chassis 296 is biased toward the initial position. Due to the downward vertical translation of the drive flange 288, and therefore the valve 284 of the pump 248, the pump 248 has been primed by applying suction to the cartridge body 252 of the cartridge 120, which draws fluid into the pump 248 to be dispensed upon actuation and / or operation of the drive unit 292. Figure 13 As shown, the drive flange 288 is engaged with the adapter 300 and fixed to the moving chassis 296 for vertical translation together within the dispenser 110, so that when the actuator 236 is depressed in the longitudinal direction, the drive flange 288, the adapter 300 and the moving chassis 296 all translate vertically upward to the stroke position for dispensing fluid. Figure 14 ) exerts sufficient force on the movable chassis 296 to cause downward vertical translation, which returns the drive flange 288, the movable chassis 296, and the adapter 300 to the initial position. In this manner, manual operation of the dispenser assembly 100 is accomplished by stroke, i.e., translation from the initial position to the stroked position and then back to the initial position. Thus, the drive flange 288, the movable chassis 296, and the adapter 300 are all configured to be movable upon the spring 472 (see Figure 14) translates the drive flange 288, the mobile chassis 296, and the adapter 300 in a first direction (e.g., vertically upward) before translating in a second direction (e.g., vertically downward) to an initial position. Additionally, the actuator 236 is configured to be depressed in a third direction (e.g., longitudinally rearward) different from the first and second directions by means of the actuator hinge 240, although other configurations are possible.

[0134] like Figure 14 4. As shown, in which the dispenser 110 is depicted as being in a closed position, the actuator 236 is in a rest position prior to being depressed or rotated about the actuator hinge 240. In the illustrated embodiment, the lever arm 242 is in contact with and pressed against the actuation surface 524 of the actuation dock 500, the spring 472 is in a rest position and extends substantially the entire length of the post 468, and the drive unit 292 is in an initial position. Thus, the drive unit 292 and the actuator 236 are provided to avoid lost motion, which can occur when movement of a first component does not cause movement of a second component that is directly connected to the first component. Here, movement (e.g., rotation) of the actuator 236 about the actuator hinge 240 immediately causes vertical translation of the moving chassis 296 and one of the adapters 300, 600, 700 when installed therein. Thus, lost motion is avoided by the actuator 236 and the drive unit 292 of the dispenser assembly 100, as shown in FIG. Figure 14 shown.

[0135] However, it is contemplated that the drive unit 292 may provide the ability to achieve lost motion with the actuator 236. For example, the actuator 236 may be provided with a shortened lever arm 242 that, in an initial position, does not contact the actuation surface 524. Instead, a gap (not shown) may exist between the lever arm 242 and the actuation surface 524 of the mobile chassis 296 such that only after the actuator 236 has pivoted a portion of the radial distance about the actuator hinge 240 (e.g., between about 3 degrees and about 10 degrees relative to the actuator hinge 240) does the lever arm 242 contact the actuation surface 524 to cause vertical translation of the drive unit 292. In this exemplary manner, lost motion may be achieved with the present dispenser assembly 100 to prevent possible damage to or obstruction of the pump 248 (see Figure 3 ) and other performance and user experience issues.

[0136] It is further contemplated that the dispenser assembly 100 in conjunction with the adapter 300 (see Figures 11 to 13 ) can provide lost motion between the drive unit 292 and the drive flange 288. For example, the adapter 300 can capture the drive flange 288 within modified first and second channels (not shown) having a larger channel height EE1 so that vertical translation of the drive unit 292 does not immediately cause vertical translation of the drive flange 288.

[0137] On the other hand, it may be desirable for the drive unit 292 to limit the amount of fluid dispensed. Figure 14 and 15 A pair of ejection limiters 770 may be coupled to the mobile chassis 296 to reduce the distance the mobile chassis 296 translates during actuation. The ejection limiters 770 are provided in the form of generally U-shaped clips that are removably coupled to the angled docking wall 512 of the actuation base 500, as shown. Figure 15 The ejection restrictor 770 is configured to allow the lever arm 242 to slide along the front panel 130 as it pivots from the open position to the closed position (see Figure 1 and Figure 2 ). Furthermore, after the front panel 130 reaches the closed position, the ejection limiter 770 causes the lever arm 242 to push the movable chassis 296 vertically upward toward the collar 266 without depressing the actuator 236. In other words, the distance between the movable chassis 296 and the collar 266 is reduced by the ejection limiter 770 positioned between the lever arm 242 and the movable chassis 296. Furthermore, the ejection limiter 770 reduces the vertical distance between the movable chassis 296 and the collar 266 by extending between the movable chassis 296 and the collar 266 at the upper end 516. In this manner, the ejection limiter 770 is configured to reduce the distance that the movable chassis 296 can translate in both directions (i.e., vertically upward and vertically downward). By shortening the vertical translation distance of the drive unit 292, the distance that the drive flange 288 translates is shortened, particularly with respect to the priming phase or return to the initial position. This results in a modified initial position that is vertically displaced above the original initial position. As a result, pump 248 is fully primed, and therefore, less fluid is drawn into pump 248 to be dispensed through actuation of drive unit 292 .

[0138] Furthermore, each of the adapters 300, 600, and 700 is associated with three different states when received within the dispenser assembly 100. For example, in the first state, the adapter 300 is received within the mobile chassis 296 and no cartridge 120 is installed therein. In the second state, the adapter 300 is received within the mobile chassis 296 and a first-type cartridge 120 is installed therein, and the adapter 300 and cartridge 120 are compatible, i.e., the first latch 404 and the second latch 408 of the first adapter correspond to the first-type cartridge 120 and / or the drive flange 288 of the pump 248, such that the predetermined distance E1 is compatible with the diameter D2. In this second state, the first-type cartridge 120 is capable of dispensing fluid through operation of the dispenser 110. In the third state, the adapter 300 is received within the mobile chassis 296, a second type of cartridge 120 different from the first type of cartridge 120 is mounted therein, and the first adapter 300 is incompatible with the second type of cartridge 120, i.e., the first latch 404 and the second latch 408 of the first adapter 300 are incompatible with the drive flange of the second type of cartridge 120, such that the predetermined distance E1 is incompatible with the diameter D2. In the third state, the incompatible drive flange is not captured between the adapter 300 and the mobile chassis 296, and therefore, the incompatible drive flange does not translate with the drive unit 292 to dispense fluid. Therefore, the first, second, and third states of the adapter 300 are mutually exclusive. It should be understood that for Figure 9 Adapter 600 and Figure 10 For the adapter 700, the first state, the second state, and the third state are the same.

[0139] In some embodiments, the adapter 300, 600, 700 is formed of a rigid plastic, such as polyoxymethylene (POM), acrylonitrile butadiene styrene (ABS), nylon, polyethylene, or any other suitable material having relatively high stiffness and stability, although other materials may also be used. The adapter 300, 600, 700 is formed as a single, unitary component, although multiple components or assemblies may be provided without departing from the scope of the present disclosure.

[0140] It is contemplated that each embodiment of the adapters 300, 600, 700 may be provided with markings, logos, coloring, or other means of communicating aspects related to compatibility with one or more cartridges 120. For example, the adapters 300, 600, 700 and the corresponding drive flanges 288 may each include the same color, numerical symbol, etc. to indicate compatibility.

[0141] Furthermore, it is contemplated that the adapters 300, 600, and 700 may be provided as a kit along with the corresponding cartridges 120. For example, the dispenser 110 may be provided with a body 140 and an adapter 300 configured to couple one type or version of cartridge 120 to the body 140. The adapter 300 defines a predetermined distance E1 that corresponds at least to the diameter D2 of the drive flange 288 of the cartridge 120. Furthermore, the dispenser 110 may be provided with an adapter 600 configured to couple another type or version of cartridge 120 to the body 140. The second adapter 600 defines a predetermined distance E2 that corresponds at least to the diameter D2 of the drive flange 288 of the cartridge 120, which is different from and incompatible with the predetermined distance E1. Thus, the dispenser 110 may be provided with both adapters 300 and 600, but only one of the adapters 300 and 600 may be accommodated within the body 140, i.e., within the slot 436 of the mobile chassis 296, at a time.

[0142] It is contemplated that the adapters 300, 600, and 700 may be provided with a greater or lesser number of catches and / or latches. Furthermore, it is contemplated that the shape of the adapters 300, 600, and 700 may differ from that shown. For example, the adapter 300 may lack latches 324 and 332 while still being operably engaged with the drive flange 288 and received within the movable chassis 296. For example, the central offset region 374 and the predetermined distance E1 of the adapter 300 provide for a snap-fit ​​capture of the drive flange 288 having a compatible diameter D2. Furthermore, the adapter 300 is received within the slot 436 of the movable chassis 296 and is prevented from vertical movement, for example, by the upper and lower members 440 and 444, from lateral movement, for example, by the first and second bumpers 536 and 548, and from longitudinal movement, for example, by the detent 386 in the recess 390. Thus, it is contemplated that adapters of varying shapes may be used within the dispenser assembly 100.

[0143] It is further contemplated that the dispenser assembly 100 can be provided with an electronics module (not shown) (e.g., a printed circuit board (PCB)) and a power source (not shown) (e.g., a battery) for measuring, recording, transmitting, and / or displaying information related to the operation and / or status of the dispenser assembly 100. In one example, the electronics module (not shown) records or counts the frequency with which the dispenser assembly 100 is used, such as by utilizing a magnet (not shown) coupled to the mobile chassis 296 for vertical translation therewith to interact with a sensor (not shown) of the electronics module (not shown) at a specific coordinate.

[0144] Although one or more preferred embodiments have been described, it will be appreciated that various changes or modifications may be made without departing from the scope of the invention as defined in the appended claims.
