AN ADAPTOR ASSEMBLY FOR A FLUID DISPENSING SYSTEM

TECHNICAL FIELD

The present disclosure generally relates to fluid dispensing systems for dispensing skincare and cleaning products such as soaps, gels, disinfectants and the like. The disclosure is specifically directed to a dispenser adaptor assembly to be used in the fluid dispensing system to allow the use of multiple types of disposable fluid dispensing packages of refill containers and fluid pumps in the dispenser.

BACKGROUND

Fluid dispensers of various types are known. In particular, for dispensing of cleaning products such as soaps, there are a wide variety of manually or automatically actuated pumps that dispense a given quantity of the product into a user’s hand.

Consumer products may include a dispensing outlet as part of the package, actuated by a user pressing down the top of the package. Such packages use a dip tube extending below the level of the liquid and a piston pump that aspirates the liquid and dispenses it downwards through an outlet spout.

Commercial dispensers frequently use inverted disposable containers that can be placed in dispensing devices, affixed to walls or built into the counter of washrooms or the like. The pump may be integrated as part of the disposable container or may be part of the permanent dispensing device or both forming a fluid dispensing package. Such devices are robust and, if they are affixed to the wall, greater freedom is available in the direction and amount of force that is required for actuation.

One dispensing system that uses a pump to dispense a unit dose of liquid from an inverted collapsible container has been described in WO2009/104992. The pump is formed of just few elements with a resilient pumping chamber and regulator valves. Operation of the pump occurs by application of a lateral force to the pumping chamber, causing it to partially collapse and expel its contents through the outer valve. Refilling of the pumping chamber occurs through the inner valve once the lateral force is removed. The filling force is provided by the inherent resilience of the wall of the pumping chamber, which should be sufficient to overcome any back-pressure due to a resistance to collapse of the container.

Other dispensing systems use an axial force for actuation of the pump i.e. directed in alignment with the direction in which the fluid is dispensed.

In many cases different dispensing systems with different types of fluid dispensing packages with the different pump types may be used at given location, e.g. a building may have a mixture of dispensers for use with different dispensing packages, in turn requiring a having the different types of fluid dispensing packages in stock instead of just having one type in the stock. Consequently, it would be desirable to provide a dispensing system that could operate in different operating dispensing solutions, e.g. in axially operating dispensing solutions as well lateral operating dispensing solutions.

SUMMARY

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

In the following, the fluid dispensing system and the adaptor assembly according to the disclosure will be exemplified by a few exemplary embodiments. However, this disclosure should not be construed as limited to these exemplary embodiments. Otherfluid dispensing system and adaptor assembly embodiments may also be considered within the scope of the appended claims. Disclosed features of example embodiments may be combined as readily understood by one of ordinary skill in the art to which this disclosure belongs. Like numbers refer to like elements throughout. Well-known functions or constructions will not necessarily be described in detail for brevity and/or clarity.

FIG. 1 shows a perspective view of a fluid dispensing system 1 in which the present disclosure as claimed in the appended claims may be implemented. The dispensing system 1 includes a reusable dispenser 100 of the type used in washrooms and the like available under the name Tork™ from SCA HYGIENE PRODUCTS AB. The dispenser 100 is described in greater detail in WO2011/133085, the contents of which are incorporated herein by reference in their entirety. It will be understood that this embodiment is merely exemplary and that the present disclosure may also be implemented in other dispensing systems.

The dispenser 100 includes a rear portion 110 and a front portion 112 that engage together to form a closed housing 116 that can be secured using a lock 118 at an upper portion 101 of the dispenser 100. The housing 116 is affixed to a wall or other surface by a bracket portion 120. At a lower portion 102 of the dispenser and a lower side of the housing 116 is an actuator 124, by which the dispensing system 1 may be manually operated to dispense a dose of cleaning fluid or the like.

FIG. 2 shows in perspective view the dispenser 100 with the housing 116 in the open configuration and with a disposable and replaceable fluid container 200 contained in a compartment 150 therein. The replaceable fluid container 200 comprises a fluid reservoir 250 and a fluid pump 300. The reservoir 250 is a 1000 ml collapsible reservoir of the type described in WO2011/133085 and also in WO2009/104992, the contents of which are also incorporated herein by reference in their entirety. The reservoir 250 is of generally cylindrical form and is made of polyethylene. The skilled person will understand that other volumes, shapes and materials are equally applicable and that the reservoir 250 may be adapted according to the shape of the dispenser 100 and according to the fluid to be dispensed. At the lower portion of the dispenser 100 is a pump 300 of the fluid container 200, which is activated by a user manually pushing a user operating portion of the actuator 124 to depress the pump and dispense the fluid from the container.

The present disclosure relates a fluid dispensing system 1 and an adaptor assembly to allow the use of different fluid containers 200 with different types of pumps 300.

A fluid container 200 with a pump 300a of the first type is sized to be received in the compartment 150 of the dispenser 100 without the use of an adaptor assembly. The pump of a first type is an axially compressible pump 300a, and the actuator 124 of the dispenser 100 has an engagement portion for actuating the pump 300a of the first type by axially compressing it in a vertical direction towards the upper portion 101 of the dispenser 100.

A fluid container 200 with a pump 300b of the second type requires the use of an adapter assembly of the disclosure. The adaptor assembly adapts the compartment 150 to be sized to receive a fluid container 200 having a pump of a second type within the dispenser 100 so as to allow the pump of a second type to be actuated by laterally compressing it to cause fluid to be dispensed from the fluid container. The actuator 124 can move an actuation part 420 of the adaptor assembly towards the pump 300b of the second type and laterally compress the pump.

FIG. 3 shows the fluid container 200 with the pump 300a of the first type in a side view. As can be seen, the reservoir 250 includes two portions. A hard portion 210 and a soft portion 212. Both portions 210, 212 are made of the same material but having different thicknesses. As the reservoir 250 empties, the soft portion 210 collapses into the hard portion 212 as liquid is dispensed by the pump assembly 300a. This construction avoids the problem with a build-up of vacuum within the reservoir 250. The skilled person will understand that although this is an example for the form of the reservoir, other types of reservoir may also be used in the context of the present disclosure, including but not limited to bags, pouches, cylinders and the like, both closed and opened to the atmosphere. The container may be filled with soap, detergent, disinfectant, skincare formulation, moisturizers or any other appropriate fluid and even medicaments. In most cases, the fluid will be aqueous, although the skilled person will understand that other substances may be used where appropriate, including oils, solvents, alcohols and the like. Furthermore, although reference will be made in the following to liquids, the dispenser 100 may also dispense fluids such as dispersions, suspensions or particulates.

At the lower side of the fluid container 200, there is provided a pump 300a of the first type that has an outer configuration that corresponds substantially to that described in WO2011/133085. The fluid container has a rigid neck 214 provided with a connecting flange 216. The connecting flange 216 engages with a stationary sleeve 310 of the pump assembly 300a. The pump assembly 300a also includes a sliding sleeve 312, which terminates at an orifice 318. The sliding sleeve 312 carries an actuating flange 314 and the stationary sleeve has a locating flange 316. Both the sleeves 310, 312 are injection molded of polycarbonate although the skilled person will be well aware that other relatively rigid, moldable materials may be used. In use, as will be described in further detail below, the sliding sleeve 312 is displaceable in an axial direction A by a distance D with respect to the stationary sleeve 310 in order to perform a single pumping action.

FIGS. 4A and 4B show partial cross-sectional views through the dispenser 100 of FIG. 1, illustrating the pump 300a of the first type in operation. According to FIG. 4A, the locating flange 316 rests on front and rear shelves 130, 131 and is engaged by a locating groove 135 formed between the rear shelf 131 and a pin 136 on the rear portion 110. The actuator 124 is pivoted at first pivot 132 to the front portion 112 and includes an engagement portion 134 that engages beneath the actuating flange 314.

FIG. 4B shows the position of the pump 300a of the first type once a user has exerted a force P on actuator 124. In this view, the actuator 124 has rotated anti-clockwise about the first pivot 132, causing the engagement portion 134 to act against the actuating flange 314 with a force F, causing it to move upwards. Thus far, the fluid dispensing system 1 comprising a fluid container 200 with a pump 3 of the first type and its operation may essentially be the same as that of the existing system known from WO2011/133085.

The fluid dispensing system 1 has so far been described in view of using the dispenser 100 together with the fluid container 200 with a pump 300a of the first type. It is desirable to be able to use the fluid container 200 with a pump 300b of the second type in the dispenser 100 described above without affecting the possibility of still having the possibility to load the dispenser 100 with a fluid container 200 having a pump 300a of the first type. A removable adaptor assembly according to the present disclosure provides this possibility. In the following, the fluid dispensing system 1 and the adaptor assembly will be exemplified in more detail by reference to enclosed drawings and a number of exemplary embodiments.

FIG. 5 shows a perspective view of a fluid container 200 with the pump of a second type. As can be seen, the reservoir 250 is for the sake of simplicity shown to be of a generally cylindrical form. Nevertheless, the skilled person will understand that the reservoir 250 may have the same construction as described above in relation to the fluid container 200 shown in FIG. 3. The skilled person will also understand that any other types of reservoir that has been described above and that may be used with the container shown in FIG. 3 may also be used in the context of the fluid container 200 with the pump of a second type. The container may be filled fluids such as soap, detergent, disinfectant, skincare formulation, moisturizers or any other appropriate fluid as mentioned above in relation to FIG. 3.

At the lower side of the fluid container 200, there is provided the pump 300b of the second type that has an outer configuration of an elongated and elastic tube forming a resilient pump chamber 300b. The chamber is in fluid communication with an inside of the fluid reservoir and is connected to a rigid neck 214a of the fluid reservoir by a connector cap 360 for connecting and sealing the fluid reservoir to the chamber. A nozzle 365 is provided at the lower end of the chamber. A valve may be arranged in the chamber 300b close to the nozzle 365 to prevent liquid from dripping out of the liquid container, when the chamber is not squeezed. Similarly, a valve may be arranged between the chamber300b and the fluid reservoir in order to prevent liquid from being pressed back into the reservoir when the chamber is being squeezed. Such valves are known in the art. An example of a pump of this type and an example of a connection of the pump to the fluid reservoir are described in WO2009/104992. The skilled person will understand that although the elongated and elastic tube chamber 300b is an example of a pump 300b of the second type, other types of pumps of the second type may also be used in the context of the present disclosure, including pump of a flexible or resilient pump chamber of other shapes than an elongated and elastic tube chamber 300b.

FIGS. 6A-6C show an embodiment of an adaptor assembly 400 to be used with a fluid container 200 with a pump 300b of the second type, in particular the fluid container 200 with the elastic and elongated tube chamber 300b as shown in FIG. 5.

The adaptor assembly comprises a connecting support forming the first connecting support 410 of the present disclosure for removably connecting the adaptor assembly to the fluid dispensing system 1. As shown in FIGS. 6A-6C, the first connecting support 410 is a disc-shaped plate 410;470 with a central through opening 412 cross the main plane of the plate. The plate has a shape and outer dimensions to allow it to rest on seat of the dispenser 100 formed by the shelves 130 and 131 of the dispenser 100 as well as to be engaged with the locating groove 135 at the rear shelf 131 on the rear portion 110 of the dispenser 100 as described herein in relation to FIGS. 3 and 8. The thickness of the plate is also selected to match the engagement means described in more detail herein below, see FIG. 7. The illustrated connecting support also forms a fluid container support 470 configured to be received in the compartment 150 of the dispenser 100 for holding the fluid container 200 in a desired position in the compartment 150 of the dispenser 100. This is provided by the central through opening 412 having a circular shape matching the dimensions and shape of the connector cap 360 as shown in FIG. 5. The plate forms a seat for the connector cap 360 to rest on by a laterally protruding flange 368 configured at the upper end of the connector cap 360, the flange 368 contacting and resting on a portion of an upper surface 435 of the plate close to the through opening 412 thereof and the remaining portion 367 of the connector cap 360 below the flange 368 is configured to protrude downwards through the through opening 412 of the plate. See FIGS. 5 and 6A-6C.

The skilled person will understand that although the disc-shaped plate 410;470 with the central through opening 412 is an example of a connecting support as well as a fluid container support 470 to be used in the context of the present disclosure, other types of connecting supports and fluid container supports 470 for the fluid container 200 may be used in the context of the illustrated adaptor assembly 400, including supports of other shapes than the disc-shaped plate with the central through opening 412, including but not limited to plates having in part a circular shape with two or more straight edges or an outer polygonal shape such as an hexagonal or octagonal shape still having portions resting on the seat of shelves 130 and 131 of the dispenser 100. The skilled person also appreciates that the circular through opening 412 may adopt other shapes, including but not limited to a polygonal shape that still may form the seat for fluid container 200 and the connector cap 360 or the like. The skilled person also understands that the plate may adopt forms such as one or more U-shaped formed plates or the like adopting the circular shape that the dispenser 100 has in the area of the shelves 130;131, e.g. two C-shaped plates, each configured to rest on the respective shelf 130; 131 and having an outer shape matching dispenser surrounding. These plates may be kept together by one or more connecting means or portions, means arranged below or above the plates and connected to suitable plate surfaces.

The adaptor assembly 400 further comprises an actuation part 420 as shown in FIGS. 6A-6C. The actuation part 420 includes an elongated arm 422 extending in a longitudinal direction (L1) thereof between two opposite ends of the arm. The first end 424 is configured to form a snap connection 414 with a corresponding recess 414 in the disc-shaped plate in an area between an edge and the central opening 412 of the plate to allow the actuation part 420 to be connected to the first connecting support 410. The arm 422 will then extend in a direction (L1) forming an angle to the main plain of the plate. A second end of the arm carries an actuation head 426 comprising a first contact surface 427 for abutting against the user actuator 124 and a second contact surface 428 for abutting against the pump 300b of the second type. The actuation head 426 projects outwardly from the second end of the arm in two opposing directions (W;X) being substantially perpendicular directions to the longitudinal direction (L1) of the actuation arm 422 to form the first and second contact surfaces 428;427 facing away from each other. The first contact surface 427 is convex in its shape to allow a contact to the actuator 124 in a form-fit manner.

The snap connection is configured to form a second pivot 418 in the fluid dispensing system 1., wherein the actuation part 420 can pivot about the second pivot 418. The pivot function is provided by forming two tapering portions 423 on opposite sides of the arm close to the first end 423 that snap into the recess 414 that is tapering from both sides of the plate, wherein a pivotal movement of the arm 422 becomes possible along one plane. In this way, actuation part 420 can pivot about the second pivot 418 and allow the head to be moved along a rotation direction (Z) between a non-actuated position and a fully actuated position, to allow fluid to be dispensed from the fluid container 200, when the adaptor assembly 400 is mounted in the dispenser 100 together with the fluid container 200.

The skilled person will understand that although the actuation part 420 being pivotally connected to the connecting support and having the actuation head 426 is an example of a actuation part 420 being movably connected to the connecting support and carrying the two connection surface, pump 300b of the second type, other actuation parts of this type may be used, including but not limited to other shapes of the head such as a head having a ball-formed shape and a first contact surface 427 being concave to match the pump shape of the second type or convex to better support complete dispensing of the fluid. The skilled person also appreciates that other types of movable connections may be used, including but not limited to a second pivot 418 formed by hinge connection or by a living hinge.

Instead of forming a pivotal connection between the actuation part 420 and the connecting support, the skilled person also envisages that the arm may be fixedly connected to the connection portion and in part or completely be made flexible from the non-actuated position to the fully actuated position in the same direction (Z) as for the actuation part 420 being pivotally connected to the connection part. The skilled person appreciates that the arm may be made flexible by using an elastic and flexible plastic material of olefin plastics such as polypropylene and selecting shapes and dimensions suitable for the purpose.

As further shown in FIGS. 6A-6C, the adaptor assembly 400 comprises a fixed dolly 430 configured to abut against the pump 300b of the second type, when mounted in the fluid dispensing system 1. The dolly 430 is fixedly connected to the disc-shaped plate on the same side of the plate as the actuation part 420, but at an opposing side of the central through opening 412 of the plate. The dolly 430 comprises a supporting structure extending from the plate in a perpendicular direction to the main plan of the plate to a portion having a protruding portion 432 thereof extending towards the actuation part 420 with a dolly surface 434 configured to abut the pump 300b of the second type, wherein the dolly surface 434 faces the actuation part 420. In this configuration, the pump 300b of the second type is able to be positioned between the second contact surface 428 of the actuation part 420 and the fixed dolly 430 and, when a force is applied to the actuation part 420 to move the actuation head 426 towards the pump, the pump 300b is compressed between the second contact surface 428 of the actuation head 426 and the dolly surface 434 causing fluid to be dispensed from the pump. In FIGS. 6A-6C, the dolly surface 434 is shown as flat. The skilled person appreciates that the dolly surface 434 may adopt any suitable shape for acting as a fixed dolly 430 and matching the second surface of the actuation part 420, e.g. the dolly surface 434 may adopt an inclined, rounded, convex or concave surface. The dolly 430 may be divided into several dolly portions or fixed dollies, each presenting a dolly surface 434. In this way the fixed dolly 430 may be adjusted to provide the proper counter force to the actuation part 420 for providing a proper dispensing action.

A protruding pin 436 is provided at a surface facing away from the dolly surface 434. As will be further illustrated in FIGS. 8A to 8B and related description hereinbelow, this pin 436 acts as a positioning means for engaging corresponding recess 142 in the rear portion 110 of the dispenser 100 and this provides a correct positioning of the adaptor assembly 400 in the dispenser 100 during the assembly of the fluid dispensing system 1. The engagement between the pin 436 and recess 142 also prevents a rotational movement of the adaptor assembly 400 in the dispenser 100, in which the adaptor assembly 400 is mounted. The skilled person appreciates that the positioning means may adopt any suitable shape or form that may assist in the positioning of the adaptor assembly 400 in the dispenser 100 and in preventing any movement of the adaptor assembly 400 in the dispenser 100, e.g. by providing frictional contact between the adaptor assembly 400 and the dispenser 100 of any other shapes that in a for-fit manner prevents the rotational and/or axial movement of the adaptor assembly 400 mounted in the dispenser 100. The positioning means may also be configured at other parts of the adaptor assembly 400. Further examples of positioning means will be described hereinbelow.

Suitable materials for forming the adaptor assembly may be aluminum or any suitable plastics such as olefin plastics, e.g. polyethylene or polypropylene. The adaptor assembly may be formed by injection molding, 3D printing or any other suitable method known to skilled person. The mentioned materials and forming of the assembly can be used for all embodiments described herein.

Furthermore, the described adaptor assembly may have the following examples of dimensions. The circular plate may have an outer diameter of 50 mm and the diameter of the through opening may be 31 mm. The thickness of the plate may be 4 mm, which provides a frictional holding by the engaging means 140 described hereinbelow. The actuation part extend from the plate with a length of 38 mm and the dolly extends from the plate with a length of 39 mm. The dolly surface has a width of about 12 mm and a height of about 13 mm. The second contact surface has a width of about 13 mm and a height of 9 mm. The diameter of the elongated and elastic tube chamber may be 14 mm and a length from the cap of about 56 mm.

FIG. 7 schematically illustrates an assembly of a fluid dispensing system 1 including the dispenser 100 of FIG. 1, a disposable container of FIG. 5 and the adaptor assembly 400 of FIGS. 6A-C.

At the front portion 112 of the dispenser 100, the housing forms a front cover 113 being pivotally connected to the rear portion 110 at the lower portion 102 thereof. The front cover 113 is opened by unlocking the lock 118 at the upper end thereof and rotating the cover about its pivot at the lower end to expose the interior of the dispenser 100. At the lower portion of the rear portion 110 is the portion for holding fluid container 200 and the pump. The adaptor assembly 400 is mounted in the dispenser 100 by inserting it through a holding opening 139 for holding the fluid container 200 at the lower portion 102 of the dispenser 100 as best shown in FIGS. 8A-8C, showing enlarged views of the lower portion of the interior inside the dispenser 100 with and without the adaptor assembly 400 inserted and fixed in the dispenser 100 as viewed from an angle above towards the rear portion 110 of the lower portion 102. As shown in FIG. 8A, the holding opening 139 is of circular shape and the rear portion 110, the rear shelf 131, locating groove 135 formed between the rear shelf 131 and a pin 136 are arranged at the rear portion 110 as described hereinabove in relation to FIG. 4A and to the fluid container 200 with the pump 300a of the first type.

As also shown in FIG. 8A, the locating groove 135 extends rearwardly through an opening 137 formed in the wall of the rear portion 110 to form a positioning opening 137. The purpose of this positioning opening 137 will be explained in more detail below in relation to other embodiments of the adaptor assembly 400.

Below the holding opening 139 at the lower portion 102 forming the part for housing the fluid pump of a fluid container 200, the rear portion 110 has two vertical flanges 141a;141b extending therefrom towards the front. These flanges form a positioning recess 142 therebetween. The adaptor assembly 400 is inserted into the holding opening 139 with the side of the connection part/plate carrying the actuation part 420 and the fixed dolly 430 facing downwards towards the lower portion 102 of the dispenser 100 and with the fixed dolly 430 being positioned towards the rear portion 110 of the dispenser 100. When the adaptor is fully inserted, the first connecting support 410 in the form of plate rests on the front and rear shelves 130;131 and engages the locating groove 135 between the rear shelf 131 and a pin 136, see FIG. 8B including the enlarged portion thereof. Furthermore, the protruding pin 436 of the fixed dolly 430 engages the positioning recess 147 formed by the vertical flanges 141a;141b in the rear portion 110 of the dispenser 100. This engagement provides a correct positioning of the adaptor assembly 400 in the dispenser 100 during the insertion of the adaptor assembly 400 in the fluid dispenser 100. The engagement between the pin 436 and recess 147 also prevents a rotational movement of the adaptor assembly 400 in the dispenser 100.

As also shown in FIGS. 8A-8C, the dispenser 100 includes engaging means 140 for holding the disc-shaped plate in place in the dispenser 100. As the disc-shaped plate also forms the fluid container support 470 in this embodiment, the provision of the engaging means 140 also provides means for holding the fluid container support 470 in place when inserting the fluid container 200 into the dispenser 100, using the dispenser 100 and removing the fluid container 200 from the dispenser 100. The skilled person appreciates that the engaging means 140 now described can be used together with any fluid container support 470 described herein.

The engaging means 140 comprises an element being displaceable between a non-holding position to a holding position. The illustrated engaging means 140 is a C-shaped element that is displaceable in a horizontal plane from the non-holding position as shown in FIG. 8B in a rearward direction to the holding position as shown in FIG. 8C. In the holding position, the engaging means 140 has portions 140a,140b engaging with the disc-shaped plate. The plate may have thickness that provides the engaging means 140 to be locked in the holding position by a frictional interaction with the plate. The skilled person understands that the plate may also comprise a pattern of cut-outs or protrusions which engages with the engaging means 140.

The skilled person understands that engaging means 140 can take a number of forms, e.g. a bayonet-type fitting, a screw fitting, one or more moveable jaws or a “click”-fitting in the dispenser 100 into which the adaptor assembly 400 or fluid container support 470 engages. The engaging means 140 may be a fixed component of the dispenser 100 or may be moveable within said dispenser 100. If the engaging means 140 is moveable within the dispenser 100, it may be sprung or otherwise resiliently arranged such that it is displaced upon insertion of the adaptor assembly 400 into the dispenser 100, but returns to an engaged position upon correct placement of the fluid container 200. Engaging means 140 may also be manually activated as the shown example is. The engaging means 140 may comprise one or more angled surfaces which promote correct insertion and engagement of the fluid container 200 in the dispenser 100.

As schematically illustrated in FIG. 7, the next step in the assembly of the fluid dispensing system 1 is to insert the fluid container 200 into the dispenser 100 now holding the adaptor assembly 400. The fluid container 200 is inserted with its pump of an elongated and elastic tube chamber 300b into the central through opening 412 of fluid container support 470 being the disc-shaped plate until the connector cap 360 of the fluid container 200 with its flange 368 rests on the seat formed in the dispenser 100 as described hereinabove and also envisaged from FIG. 9A. FIG. 9A also illustrates that the fluid container 200 is inserted so that the elongated tube of the pump is placed between the second surface of the actuation part 420 and the dolly surface 434 of the fixed dolly 430.

The assembly of the fluid dispensing system 1 is then finalized by closing the dispenser 100 by moving the upper portion of the front cover to the rear portion 110 and, optionally locking the cover to the rear potion. The dispenser 100 is then ready for use.

FIGS. 9A and 9B show a perspective view of a lower portion 102 of the fluid dispensing system 1 of FIG. 7, when assembled to a fluid dispensing system 1 as shown in FIG. 1, with a portion of the dispenser 100 cut away to show details of the interior of the fluid dispensing system 1 in operation.

According to FIG. 9A, the fluid container 200 rests on its seat in the dispenser 100 that is formed by the disc-shaped plate forming the fluid container support 470 of the adaptor assembly 400 being removably mounted in the dispenser 100. The fluid pump 300b of the second type being an elongated and elastic tube chamber 300b extends downwards from the fluid container 200 and between the second surface of the actuation part 420 and the dolly surface 434 of the fixed dolly 430 to the nozzle 365 at the bottom of the dispenser 100. The nozzle 365 is placed at the lowermost part of the dispenser 100 so as to prevent the risk of having any dispensing part contaminated upon dispensing any fluids from the fluid container 200, but at the same time not being clearly visible for a user, when using the dispenser 100. The position of the nozzle 365 depends on, for example, the dimensions of the fluid container 200 and the position the fluid container 200 can have in the dispenser 100. The skilled person appreciates how to adopt the fluid container support 470 or its position so as to adjust the position of the nozzle 365. The adaptor assembly 400 may also be modified to adjust the position it has in relating to pump as well as to the shape of the pump and the maximum volume desired to be dispensed from the fluid container 200. Some examples of dimensions and shapes of the adaptor assembly 400 have been presented hereinabove for the embodiment now shown in FIG. 9A. These dimensions and shapes may be envisaged for other embodiments shown herein. For example, the dimensions of the actuation head 426 and the fixed dolly 430 are adjusted so that a pump placed therebetween in the dispenser 100 and in the non-actuated position should be in non-compressed and non-distorted form, and still providing a sufficient dispensing when actuated.

In FIG. 9A, the actuator 124 is pivoted at first pivot 132 to the front portion 112 and includes a contact surface 145 that faces the compartment 150 of the dispenser 100 and is configured to abut the first contact surface 427 of the actuation part 420. The surface 145 of the actuator 124 is concaved-shaped to match the convex-formed first contact surface 427. In this view, the actuation part 420 is kept in its non-actuated position between the actuator 124 and the elongated and elastic tube chamber 300b forming the pump 300b of the second type.

FIG. 9B shows the fluid dispensing system 1 once a user by the hand has exerted a force P on actuator 124, wherein user actuator has displaced the actuation part 420 and the actuation head 426 from its non-actuated position towards an actuated position, and thereby transferred an actuation force TF from the actuation part 420 via the second surface to the pump. The pump has been laterally compressed towards the rear portion 110 of the dispenser 100 and the dolly surface 434. This has caused fluid to be dispensed downwardly in a direction Y from the fluid container 200. In this view, the actuator 124 has rotated anti-clockwise about the first pivot 132 to cause the actuation of the dispenser 100. Once the user removes the hand from the actuator 124, the actuator rotates clockwise toward the front portion 112 to the position it had before the user exerted the force P on it. The actuation part 420 is then returned to its non-actuated position, when refilling of the pumping chamber occurs by the provision of a filling force being provided by the inherent resilience of the wall of the pumping chamber (not shown).

FIGS. 10A to 10B show an embodiment of an adaptor assembly 400 to be used with a fluid container 200 with a pump 300b of the second type, in particular the fluid container 200 with the elastic and elongated tube chamber 300b as shown in FIG. 5.

The adaptor assembly 400 is in general similar to the embodiment shown in FIGS. 6A to 6C, with a few differences only. A first difference is the shape of the actuation part 420. In this embodiment, the actuation part 420 is substantially L-shaped in its form with an elongated arm extending in a longitudinal direction (L1) thereof between two opposite ends of the arm. A first end is connected to the first connecting support 410 in any of the ways described in relation to the embodiment of FIGS. 6A to 6C, i.e. it may be pivotally connected or fixedly connected to the first connecting support 410. In the case it is fixedly connected to the first connecting support 410, the arm may be made flexible or elastic to allow the movement towards the fixed dolly 430. A second end of the arm carries an actuation head 426 comprising a first contact surface 427 for abutting against the user actuator 124 and a second contact surface 428 for abutting against the pump 300b of the second type. The actuation head 426 projects outwardly from the second end of the arm in one direction (W) being a substantially perpendicular direction to the longitudinal direction (L1) of the actuation arm to form the actuation head 426 with first and second contact surface 427;428 facing away from each other. The first contact surface 427 is here shown as an elongated planar surface for contacting a lateral flange 147 on the actuator 124 and provide a gliding surface for this flange 147, see FIG. 10C. However the shape may be modified to allow a desired contact with the flange 147 or to adopt any shape for suitably contacting a surface of the actuator 124 in a form-fit manner, e.g. to adopt the shape shown in FIG. 6B and allow the first contact surface 427 to be in contact with an actuator surface 145 just above the flange 147. The second contacting surface 428 is in this embodiment also shown as being planar. As discussed hereinabove, it may have other shapes suitable for contacting the pump.

In this embodiment, the connection support forms a circular sleeve 410 instead of a disc-shaped plate. However, this shape will in a form-fit manner rest on the same seat in the dispenser 100 as the disc-shaped plate does. This shape may provide some extra rigidity to the first connecting support 410. It may also provide some additional stabilization for the fluid container 200 supported by the connecting support being a fluid container support 470 as compared to the disc-shaped plate hereinabove. Nevertheless, the sleeve 410;470 provides a seat for the fluid container 200 in a similar way as the disc-shaped element. The sleeve contains an upper part 411 and a lower part 413, the upper part 411 having an outer diameter as well as an inner diameter that are both larger than respective dimension of the lower part 413. In this way, the sleeve forms a circular surface 411a facing downwards from the upper part 411 and configured to rest on the front and rear shelves 130;131 of the dispenser 100. In the axially extending through opening 412 of the sleeve, there is provide an upwardly facing circular edge surface 413a configured to form a seat for the flange 368 of the connector cap 360 of the fluid container 200 to rest on. Thus, the lower part 413 is configured to be positioned in the holding opening 139 below the area of the shelves 130;131. This may provide some stabilization of the adaptor assembly 400 when mounted in the dispenser 100 as well as for the fluid container 200 inserted therein. The sleeve will also encompass the fluid container 200 on the sides thereof.

Furthermore, a pin 439 extends rearwards from the upper part 411. This pin 439 acts as a positioning means for engaging the corresponding positioning opening 137 formed in the rear portion 110 at the locating groove 135 as shown in FIGS. 8A and 10C. The engagement between the pin 439 and the positioning opening 137 provides a correct and simple positioning of the adaptor assembly 400 in the dispenser 100 during the insertion of the adaptor assembly 400 in the fluid dispenser 100. The engagement between the pin 439 and the positioning opening 137 also prevents both an axial and a rotational movement of the adaptor assembly 400 and the fluid container support 470 in the dispenser 100, when mounted therein. The adaptor assembly 400 as shown inf FIGS. 10A to 10C does not have any positioning means on the fixed dolly 430. However, as for the embodiment of shown in FIGS. 6a to 6C, this embodiment may be used with a positioning means arranged on any suitable part, e.g. on the fixed dolly 430, for connecting corresponding parts in the dispenser 100 in a suitable manner.

In FIGS. 10A to 10B, the fixed dolly 430 adopts a L-shaped form with a substantially rigid arm with one end fixedly connected to the bottom of the sleeve. The other end of the rigid arm has a dolly portion extending towards the second surface of the actuation part 420 with a concave dolly surface 434 facing the actuation part 420. The concave surface matches in form the elongated and elastic tube chamber 300b. Furthermore, as shown the second surface of the actuation part 420 may have a width a horizontal plane that is smaller than the width of a cavity formed at the dolly surface 434 to allow the actuation part 420 to move into the cavity, when the actuation part 420 is moved to an actuated position. This may provide a good compression of the elongated and elastic tube chamber 300b during the dispensing of fluid. As mentioned hereinabove, the shapes of the different surfaces may be selected depending on the type of fluid container 200 used or the desired dispensing of the fluid.

An assembly of a fluid dispensing system 1 including the dispenser 100 of FIG. 1, a disposable container of FIG. 5 and the adaptor assembly 400 of FIGS. 10A to 10B resembles the assembly of the fluid dispensing system 1 including an adaptor assembly 400 shown in FIGS. 6A to 6C. Attention is drawn to the fact that the embodiment shown in FIGS. 10A and 10B has the positioning means in form of pin 439 in a different position than the adaptor assembly 400 shown in FIG. 6A, for example. As mentioned above, the pin 439 shown in FIGS. 10A and 10C is configured to engage the corresponding positioning opening 137 formed in the rear portion 110 at the locating groove 135 as shown in FIGS. 8A and 10C. Thus, the assembly of the adaptor part may then be very simple by just inserting adaptor assembly 400 into the holding opening 139 with the side of the sleeve carrying the actuation part 420 and the fixed dolly 430 facing downwards towards the lower portion 102 of the dispenser 100. The pin 439 as well as the fixed dolly 430 should be positioned towards the rear portion 110 of the dispenser 100 to secure that the pin 439 is inserted in the corresponding positioning opening 137 in the wall of the rear portion 110 and that the sleeve rests correctly on its seats in the dispenser 100, i.e. the shelves 130;131.

The engaging means 140 as shown in FIGS. 8A and 8C may then be used to hold the sleeve in position within the dispenser 100 as described hereinabove for engaging and holding the disc-shaped plate. The fluid container 200 is inserted into the dispenser 100 holding the adaptor assembly 400 in a similar way as described hereinabove, wherein an assembled fluid dispensing system 1 will rest on the sleeve as described above.

As illustrated in FIG. 10C and in an assembled fluid dispensing system 1, the positions of the actuation head 426 as well as the dolly surface 434 is slightly below the corresponding parts of the embodiment shown in FIG. 9A. This changes the position for squeezing the elongated and elastic tube chamber 300b. The skilled person appreciates that either position may work depending on the position of the elongate and elastic tube chamber 300b and the properties of the tube chamber 300b. Furthermore, even though the position is suitable for the shape the actuation part 420 has for allowing the first surface to be in contact with the rearwardly directed lateral flange 147 of the actuator 124, the skilled person appreciates that the head portion of the actuation part 420 with the second surface may be arranged in a more upwardly placed position. The position or shape of the fixed dolly 430 could then be adjusted accordingly.

The operation of the fluid dispensing system 1 including the adaptor assembly 400 of as shown in FIG. 10C resembles in large the operation of the fluid dispensing system 1 illustrated in FIGS. 9A and 9B, except that the actuation part 420 compresses the elongated and elastic tube chamber 300b at the lower portion thereof and that the tube is compressed into a cavity formed by the dolly surface 434.

FIGS. 11A to 11B show an embodiment of an adaptor assembly 400 to be used with a fluid container 200 with a pump 300b of the second type, in particular the fluid container 200 with the elastic and elongated tube chamber 300b as shown in FIG. 5.

This adaptor assembly 400 has two separate parts instead of an adaptor assembly 400 of a single unit as described hereinabove. This provides a simple adaptor assembly 400 with a minimum of material used. The adaptor assembly 400 contains a first part forming the actuation part 420 with a first connection portion in the form of a lateral slit 410 that in a form-fit manner can be attached to a rearwardly directed lateral flange 147 of the actuator 124. The first contact surface 427 of the actuation part 420 close to the slit 410 may also in form match surface areas of the actuator 124 surrounding the flange, when the first part is mounted correctly to the actuator. The general shape of the actuation part 420 corresponds in large to the actuation head 426 shown in FIGS. 10A and 10B.

The second part of this embodiment includes a second connecting support 460 and also acting as a fluid container support 470 with a fixed dolly 430 attached thereto. This second part corresponds to the adaptor assembly 400 shown in FIGS. 10A and 10B with the difference of not containing any actuation part 420.

An assembly of a fluid dispensing system 1 including the dispenser 100 of FIG. 1, a disposable container of FIG. 5 and the adaptor assembly 400 of FIGS. 11A to 11B differs from the assembly of the fluid dispensing system 1 including the embodiment of FIGS. 10A and 10C in that the first part needs to be removably attached to the dispensing system by fitting the slit 410 of the first part to a central portion of the flange 147 of the actuator 124. The attachment of the first part can be carried out before or after the assembly of the second part into the dispenser 100. The attachment of the second part is carried out as described for the adaptor assembly 400 of FIGS. 10A and 10B. The fluid container 200 is inserted into the dispenser 100 with the second part assembled thereto.

As illustrated in FIG. 11C and in an assembled fluid dispensing system 1, the positioning of the actuation head 426 as well as the dolly surface 434 is similar to the positions of the corresponding part as shown for the embodiment of FIG. 10C. The skilled person appreciates that the first part forming the actuation part 420 may be shaped to present the second surface in a more upwardly placed position. The position or shape of the fixed dolly 430 could then be adjusted accordingly.

The operation of the fluid dispensing system 1 including the adaptor assembly 400 of as shown in FIG. 11C resembles in large the operation of the fluid dispensing system 1 illustrated in FIGS. 9A and 9B, except that first part forming the actuation part 420 becomes part of the actuator 124 and is movable together with the actuator 124, wherein a user force (P) applied to the actuator 124 displaces actuation part 420 from a non-actuated position to the actuated position, thereby compressing the elongated and elastic tube at lower portion thereof, wherein the tube is compressed into a cavity formed by the dolly surface 434.

FIGS. 12A to 12B show an embodiment of an adaptor assembly 400 to be used with a fluid container 200 with a pump 300b of the second type, in particular the fluid container 200 with the elastic and elongated tube chamber 300b as shown in FIG. 5.

This adaptor assembly 400 is divided in three separate parts instead forming an adaptor assembly 400 of two parts or as single unit. This provides a simple adaptor assembly 400 with a minimum of material used. The adaptor assembly 400 contains a first part forming an actuation part 420 with a first connection portion in the form of a lateral slit 410 that in a form-fit manner can be attached to rearwardly directed lateral flange 147 of the actuator 124. The first contact surface 427 of the actuation part 420 about the slit 410 may also in form match surface areas of the actuator 124 surrounding the flange 147, when the first part is mounted correctly to the actuation part 420. The general shape of the actuation part 420 corresponds in large to the actuation head 426 shown in FIGS. 10A ; 10B; 11A; 11B.

The second part of this embodiment includes a fixed dolly 430 with a second connecting support 460 in the form of a vertical slits 460a;460b that in a form-fit manner can be attached to vertical flanges 141a;141b arranged at the rear portion 110 as described above and shown in FIG. 8A.

This third part corresponds to the sleeve shown in FIGS. 10A and 10B forming a fluid container support 470 only. Thus, this sleeve does not connect to the actuation part 420 and the fixed dolly 430.

An assembly of a fluid dispensing system 1 including the dispenser 100 of FIG. 1, a disposable container of FIG. 5 and the adaptor assembly 400 of FIGS. 12A to 12B differs from the assembly of the fluid dispensing system 1 including the embodiment of FIGS. 10A and 10C in that the three parts of the adaptor assembly 400 needs to be attached to the dispenser 100 separately. The first part forming the actuation part 420 needs to be removably attached to the dispensing system by fitting the slit 410 of the first part to a central portion of the lateral flange 147 of the actuator 124. The second part forming the fixed dolly 430 needs to be removably attached to the rear portion 110 of the dispenser 100 by fitting the vertical slits 460a;460b of the second part to the two vertical flanges 141a;141b arranged at the rear portion 110 in a suitable height matching the height of the first part. The attachment of the third part is in general carried out as described for the adaptor assembly 400 of FIGS. 10A and 10B. The attachment of the different parts to the dispenser 100 can occur in any order before inserting the fluid container 200 into the dispenser 100.

As illustrated in FIG. 12C and in an assembled fluid dispensing system 1, the positioning of the actuation head 426 as well as the dolly surface 434 is similar to the positions of the corresponding parts shown for the embodiments of FIGS. 10C and 11C. The skilled person appreciates that the first part forming the actuation part 420 may be shaped to present the second surface in a more upwardly placed position. The position or shape of the fixed dolly 430 could then be adjusted accordingly.

The operation of the fluid dispensing system 1 including the adaptor assembly 400 as shown in FIG. 12C resembles in large the operation of the operation of the fluid dispensing system 1 shown in FIG. 11C and as illustrated in FIGS. 9A and 9B. Thus, the first part forming the actuation part 420 becomes part of the actuator 124 and is movable together with the actuator 124, wherein a user force (P) applied to the actuator 124 displaces actuation part 420 from a non-actuated position to the actuated position, thereby compressing the elongated and elastic tube at lower portion thereof, wherein the tube is compressed into a cavity formed by the dolly surface 434.

FIG. 13A illustrates an embodiment of an adaptor assembly 400 comprising a first connecting support 410 being an elastic and flexible element with a recess 480 having a lateral dimension being larger than the pump has in a lateral direction. As shown in FIG. 13A, the elastic and flexible element has a circular shape with a central through opening 480 therein forming the recess. The actuation part 420 and the fixed dolly 430 are carried by the element and form portions protruding from opposite side within the recess such that the pump 300b of the second type is able to be configured between the second contact surface 428 of the actuation part 420 and the fixed dolly 430. As illustrated in FIG. 13B, the elongated and elastic pump chamber of fluid container 200 as shown in FIG. 5 can be inserted into the through opening 480 of the ring and be placed between the two protruding portions, wherein the elastic ring securely biases the opposite protruding portions to the pump in a non-compressing and non-distorting manner, i.e. in a non-actuated position. The skilled person understands that the dimensions, shapes and materials may be adjusted to provide proper biasing of the structure in the non-actuated position.

FIG. 13C shows a partial cross-sectional view of an embodiment of a fluid dispensing system 1 viewed from the side. The fluid dispensing system 1 comprises fluid container 200 as shown in FIG. 5 and the adaptor assembly 400 shown if FIG. 13B.

The flexible and elastic element forms both the first connecting support 410 for holding the fixed dolly 430 and the actuation part 420 in the form of the two portions protruding into the through opening 480 of the flexible and elastic element, here shown as an elastic ring. The elastic ring with the protruding portions may form a fluid container support 470 as well. It provides a connection to fluid container 200 and is configured to rest on front and rear portions 110;112 of the dispenser 100 at a lower portion 102 of the dispenser 100. In Thus, the diameter of the elastic ring has a dimension to just fit in the seat between the rear portion 110 and the actuator 124. Optionally, the adaptor assembly 400 may additionally, or as an alternative, comprise the fluid connection support of the embodiment shown in FIGS. 12A and 12B, or the like.

An assembly of a fluid dispensing system 1 shown in FIG. 13C including the dispenser 100 of FIG. 1, a disposable container of FIG. 5 and the adaptor assembly 400 of FIGS. 13A to 13B is simple and contains a few steps only. Following the opening of the front cover of the dispenser 100, the fluid container 200 is inserted into dispenser 100 from the top with the elongated and elastic pump chamber inserted through the holding opening 139 of the dispenser 100. The elastic and flexible element is then from the bottom of the dispenser 100 brought on to the elongated and elastic tube chamber 300b of the fluid container 200 inserted in the dispenser 100 so that the tube chamber 300b is placed in between the protruding portions of the elastic ring, of which one should be configured close to the rear position and the other one close to the front portion 112 and the actuator 124 thereof, see FIG. 13C. The height can be adjusted to provide a proper fluid connection support and dispensing.

The operation of the fluid dispensing system 1 including the adaptor assembly 400 as shown in FIG. 13C resembles in general the operation of the fluid dispensing system 1 illustrated in FIGS. 9A and 9B. When a user force (P) is applied to the user actuator 124, the elastic ring is compressed from a non-actuated position to an actuated position, i.e.it is compressed towards the dolly 430 and rear portion 110 of the dispenser 100 so that the elongated and elastic pump chamber is laterally compressed between said second surface and the fixed dolly 430 causing fluid to be dispensed from the fluid container 200. The skilled person understands that the dimensions, shapes and materials may be adjusted to provide proper biasing of the structure in the non-actuated position and to provide the possibility for a user to press the actuator 124 by the hand to actuate the dispensing of fluid and to return the elastic ring to the non-actuated position, when the user removes the hand from the actuator 124. The adaptor assembly 400 may be therefore be made of a plastic material such as olefin plastics, e.g. polyethylene or polypropylene.

As the skilled person will appreciate, it is intended that the detailed description be regarded as illustrative and that many embodiments and alternatives are possible within the scope of the present disclosure as defined by the appended claims. For example, the adaptor assembly may adopt other shapes than the ones shown in the drawings, e.g. the adaptor assembly may comprise a unit with the first connecting part and the actuation part as illustrated for the embodiments of FIGS. 6A-6C and FIGS. 10A-10B, and the fixed dolly may be arranged as illustrated for the embodiment of FIGS. 12A and 12B.

Attention is drawn to the fact that use of the adaptor assembly does not require the removal of the engagement means 134 of the actuator used for axial compression of the pump 300a of the first type, see Figures.
