This application is a National Stage application of PCT/EP2020/078958, filed Oct. 14, 2020, which is incorporated by reference in its entirety herein.
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 dispenser adaptor assemblies 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 a dispenser. The disclosure is also directed to a dispenser.
Fluid dispensers of various types are known. In particular, for dispensing of cleaning products such as soaps and hand sanitizers, 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. Such devices may also use sensors that identify the location of a user's hand and cause a unit dose of the product to be dispensed. This avoids user contact with the device and the associated cross-contamination. It also prevents incorrect operation that can lead to damage and premature ageing of the dispensing mechanism.
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 is enough 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 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 laterally operating dispensing solutions.
It is desirable to have a dispensing system that is flexible in its operating manner and reliable when used to allow different types of fluid dispensing packages, yet simple, hygienic, environmentally acceptable and economical to produce.
The disclosure relates in particular to adaptor assemblies, a fluid dispensing system, and a dispenser. Embodiments are set forth in the following description and in the drawings.
Thus, there is disclosed an adaptor assembly for use in a dispenser for a fluid dispensing package of a replaceable fluid container comprising a fluid reservoir and a fluid pump. The dispenser comprises a housing and a compartment therein for containing the fluid container. The dispenser has a front portion, a rear portion, and upper and lower end portions. The lower end portion forms a dispensing end portion of the dispenser and comprising an actuator, which is displaced directly by a user or displaced via a motor for operating the dispenser to dispense a dose of a fluid from the fluid container through a nozzle at the lower end portion.
The compartment of the dispenser is sized to receive a fluid container having a pump of a first type being an axially compressible pump and the actuator has a lifter for actuating the pump of the first type by axially compressing it in a vertical direction,
The adapter assembly is used in conjunction with the dispenser to allow a use of a fluid container having a pump of a second type within the dispenser, the second type being actuated by laterally compressing it. The adaptor assembly is configured for removably connect it to the dispenser and the fluid container.
The adaptor assembly comprises a fluid container support configured to be received in the compartment of the dispenser for holding and/or supporting the fluid container having the pump of a second type in a desired position in the compartment of the dispenser.
The adaptor assembly comprises a first actuation part including a first actuation head being movable between a non-actuated position and a fully actuated position, wherein the first actuation head comprises a first contact surface for abutting against a first dolly surface and a second contact surface for abutting against the pump of the second type.
The adaptor assembly further comprises second actuation part including a second actuation head being movable between a non-actuated position and a fully actuated position, wherein the second actuation head comprises a first contact surface for abutting against a second dolly surface and a second contact surface for abutting against the pump of the second type.
The first contact surfaces of the first and second actuation heads abut against the first and second dolly surfaces in the non-actuated and the fully actuated positions.
The adaptor assembly also comprises a moving part being displaceable between a lower position and an upper position, wherein a displacement of the moving part from the lower position to the upper position moves the first and second actuation heads from their non-actuated position towards the fully actuated positions.
The lifter engages and acts on the moving part, when the adaptor assembly is mounted in the dispenser, wherein a lifting force (P) applied by the lifter on the moving part displaces the moving part between from its lower position to and an upper position, thereby transferring an actuation force (TF) from the moving part via the actuation heads to the pump of the fluid container, when mounted in the compartment, wherein the pump of the second type is laterally compressed to cause fluid to be dispensed from the fluid container.
A horizontal plane (H1-H3) through the first and second actuation heads in their fully actuated positions intersects portions of the first and second dolly surfaces that are in contact with portions the first contact surfaces of the actuation heads.
The horizontal plane (H1-H3) may intersect portions of the second contact surfaces that are in contact with the pump of the second type.
By these having these contact points, a good force transfer from the lifter 124 to the pump 300b for dispensing a dose of a fluid is secured.
As used herein, the terms “horizontal”, “lateral” and “vertical”, “uppermost” and “lowermost”, “downwards” and “upwards”, “front” and “rear”, and “upper” and “lower” or the like are to be understood as seen when a dispensing system with a dispenser and a fluid container is arranged for use, with or without the adaptor assembly.
The lifting force (P) that is applied by the lifter in the moving part may be an axial force. As used herein, by an axial or vertical force for actuation of the pump is understood to be a force directed in alignment with the direction in which the fluid is dispensed. Similarly, by a lateral force is understood to be a force substantially perpendicular to the direction in which the fluid is dispensed.
The fluid container may be adapted to be filled with a liquid such as for instance liquid soap, foam soap, alcogel, disinfecting or anti-bacterial liquid, or lotion. The flexible dispensing portion may be filled with the relevant liquid and subjected to an external force in order to dispense the liquid therefrom. The pumps described herein may be of such a size that a suitable or desired volume of around 0.5 to 1 ml, e.g. 0.6 to 0.9 ml, of the liquid may be dispensed upon performing a full dispensing stroke. The volume dispensed depends on the fluid type to be dispensed and the materials the adapter assembly are made of.
Suitable materials for forming the adaptor assembly may be aluminum or any suitable plastics such as polyoxymethylene (POM), polyamide 12 (PA 12) and 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 the skilled person. The mentioned materials and forming of the assembly can be used for all parts of the adaptor assembly and a combination of the materials may also be considered for adaptor assembly or parts thereof.
As used herein, the term adaptor or adaptor assembly is a device that converts attributes of the dispensing system or dispenser to those of an otherwise incompatible replaceable fluid container of the fluid dispensing system. The adaptor assembly should be configured for removably connect it to the dispenser and the fluid container having the pump of a second type. By removably connected here means that the adaptor assembly can be easily connected and removed from the dispenser without affecting the properties the dispenser has without the adaptor assembly.
Thus, the adaptor assembly allows for a dispensing system that could operate in different operating dispensing solutions, i.e. in axially operating dispensing solutions as well lateral operating dispensing solutions. The adaptor assembly makes the dispensing system flexible in its use and reliable when used so as to allow the use of different types of fluid dispensing packages, and yet being simple, hygienic, environmentally acceptable and economical to produce.
As mentioned hereinabove, the actuator having the lifter may be of the type that is displaced directly by a user or it may be of the type displaced via a motor for operating the dispenser to dispense a dose of a fluid from the fluid container through a nozzle at the lower end portion. If the actuator is of the type that is directly displaced by a user, it may be a user lever configured to pivot about a pivot. The user lever may then extend from the pivot towards a user operating portion of the user lever, wherein the user actuator has the lifter extending into the compartment of the dispenser to act on the moving part.
The moving part may be configured to at least partly be enclosed by a pump engagement portion of the lifter. The moving part may be configured to at least partly engage the engagement portion of the lifter in a form-fit manner.
This provides for a proper engagement between the lifter and the moving part and such a lifter may be suitable to be operably connected to a motor for operating the dispensing of a fluid.
The fluid container support may form an upper part of the actuator assembly and the moving part may form a lower part of the adaptor assembly, wherein the moving part is movably connected to the fluid container support. The first and second actuation parts may connect the fluid container support to the moving part.
The first and second dolly surfaces may form elongated sliding surfaces, against which the first contact surfaces of the actuation parts abut and along which the first contact surfaces slide or move, when the moving part is displaced from its lower position to its upper position.
The fluid container support may have a vertically extending through-opening for receiving a portion of the fluid container, wherein the through-opening extends to the front and present a front opening of the fluid container support to the surroundings.
This opening provides an easy assembly of the dispensing system and does not require the removal of the adaptor assembly from the dispenser, when the fluid container needs to be replaced.
The moving part may have a through-opening extending from the upper part to the lower part of the moving part. The through-opening may be configured to at least partly receive the pump of the second type.
The moving part may have an access opening at an upper front portion thereof to access the through-opening from the front portion, wherein the access opening forms a continuous opening with the through-opening at the upper portion of the moving part.
The moving part may have an access cavity is formed at an inner portion of the moving part that is located below the access opening and faces the through-opening of the moving part.
The openings as well as the access cavity provide an even easier assembly of the dispensing system and does not require the removal of the adaptor assembly from the dispenser, when the fluid container needs to be replaced.
The first and second dolly surfaces may form part of the moving part. The dolly surfaces may be arranged on opposite sides of the through-opening of the moving part and face each other. The dolly surfaces may then extend with oblique angles downwards and inwards in directions (C1; C2) towards each other to form a tapering cavity portion therebetween.
The provision of the dolly surfaces as described hereinabove provide a proper counter force to the actuation heads for providing a proper dispensing action, when they are moved from their non-actuated positions to their actuated positions. The first contact surfaces may abut against and slide along the dolly surfaces upon a displacement of the moving part between the lower position to the upper position. The inclined dolly surfaces allow for moving the actuation heads inwardly against the pump upon the displacement of the moving part towards an upper position.
Each one of the first and second actuation parts may comprise an elongated arm extending in a substantially longitudinal direction (L1; L2) thereof between two opposite ends of the arm. A first end may in such case be connected to the fluid container support and a second end may carry one of the two actuation heads, wherein he actuation head is movable between the non-actuated position and the fully actuated position.
The elongated arm with the actuation head provides a flexible and reliable actuation part that may be shaped and dimensioned to the desired use, e.g. it may be shaped and dimensioned for a desired volume to be dispensed.
The actuation parts may be movably connected to the fluid container support arms for allowing said movements of the actuation head between the non-actuated positions and the fully actuated positions. For example, each actuation part may be pivotally attached to the fluid container support and configured to pivot about a pivot.
This allows the actuation heads to move between non-actuated positions and actuated positions in a substantially lateral direction towards the pump. The pivot may be formed by a snap connection between the first connecting support and the actuation part, or it can, for example, be formed by a hinge connection or by a living hinge.
According another embodiment, the elongated arms may be flexible arms for allowing said movements of the actuation head between the non-actuated positions and the fully actuated positions.
This allows the actuation heads to move between their non-actuated positions and actuated positions in substantially lateral movements toward the pump. The arms may be fixedly connected to the first connecting support and in part or completely be made flexible from the non-actuated position to the fully actuated position. The skilled person appreciates that the arms may be made flexible by using an elastic and flexible plastic material of, for example, polyoxymethylene (POM) or olefin plastics such as polypropylene and by selecting shapes and dimensions suitable for the purpose.
According to yet another embodiment, the actuation heads may be movably connected to the respective arms of the actuation parts.
As mentioned hereinabove, there are some suitable materials for forming the adaptor assembly. The actuation parts may contain or be made of polyoxymethylene (POM). POM is a rather stiff plastic material that may be used to provide the flexible arms with proper flexibility and spring force to support functionality and structure of the adaptor assembly and to support the return of the actuation heads from their actuated positions to the non-actuated positions, i.e. towards the rest positions the arms have, as well as to support the return of the moving part to its lower position, when the moving part has been moved to an upper position and is movably connected to the actuation parts. Furthermore, by making the actuation heads of POM, there are provided good sliding properties between the first contact surfaces of the actuation heads and the dolly surfaces.
The fluid container support may contain or be made of polyoxymethylene (POM).
The moving part may contain or be made of olefin plastics such as polyethylene and/or polypropylene. In the case the moving part includes the dolly surfaces, the olefin plastics would provide good sliding properties between the dolly surfaces and the first contact surfaces of the actuation heads, e.g. when the latter are made of POM.
The pump of the second type may have a resilient pumping chamber. The resilient pumping chamber may be an elongated and elastic tube chamber extending downwards at the lower portion of the fluid container in a direction from the bottom of the fluid reservoir to a nozzle of the elastic tube chamber.
The adaptor assembly may further be configured so that at least a portion of each second contact surface abuts against the pump in the non-actuated position.
The possibility of this abutment may be provided by the actuation parts having the elastic and flexible arms that keeps the actuation heads in the non-actuated position such that at least portions of the actuation heads abut against pump when inserted between the actuation heads in the adaptor assembly. This provides a reliable and effective dispensing upon actuation thereof.
The adaptor assembly may further be configured so that a portion of each second contact surface extends with angle to the vertical direction in the non-actuated position, e.g. wherein each second contact surface is convex. The convex surface may convex in a vertical direction and towards the other second contact surface. The radius (r) of the convex surface may be about 10-18 mm.
During the use of the adaptor in the dispensing system, this allows for a smooth compression and deformation of the pump from an upper portion to a lower portion thereof.
The adaptor assembly may further comprise one or more positioning means for engaging corresponding one or more connecting portions in the dispenser and preventing axial and/or rotational movement of the adaptor assembly in the dispenser, and/or for preventing wrong positioning of the adapter assembly in the dispenser.
When the adaptor assembly and the fluid container having the pump of the second type are mounted in the dispenser, the energy consumption for a dispensing cycle of dispensing a fluid, by displacing the moving part from the lowermost position to its uppermost position and returning the moving part the lowermost position, may be lower than 1100 μWh, e.g. 300 to 1000 μWh or 500 to 1000 μWh.
There is further provided an adaptor assembly for use in a dispenser for a replaceable fluid container having a fluid pump being actuated by laterally compressing it
The adaptor assembly comprises an actuation part being connected to a fluid container support and movably connected to a moving part, wherein the moving part is displaceable between a lower position and an upper position.
The actuation part has an actuation head that is moveable between a non-actuated position and an actuated position, wherein the actuation head comprises a first contact surface for abutting against a dolly surface of the moving part and a second contact surface for abutting against the fluid pump, wherein the first and second contact surfaces faces away from each other.

In use, as will be described in further detail below, the sliding sleeve 312 is displaceable in an axial direction A by a distance D1 with respect to the stationary sleeve 310 in order to perform a single pumping action.
The dispensing unit 125 has a protruding portion 128 at the lower end portion 102 of the dispenser 100 that protrudes towards the front. The protruding portion 128 includes an opening 130 extending from the lower end to the upper end of the protruding portion 128. The opening 130 faces the front portion of the dispenser 100 forming a cavity 130 in the protruding portion 128 that extends in the vertical direction thereof. This cavity 130 is sized to receive the lower portion of the fluid container 200 having the pump 300a of a first type as shown in
The uppermost part of the cavity 130 forms a neck engagement portion 132 configured to partly enclose and match the shape of the neck 214 of fluid container 200 as shown in
At the lower portion of the dispensing unit 125 is the actuator 124 in the form of a lifter 124. The lifter is connected to a lifting mechanism in the rear portion of the dispensing unit 125 and a vertical movement of the lifter occurs along a vertical groove 138 formed at the rear of the inner wall 131 in the cavity 130 through which groove 138 the lifting mechanism connects to the lifter 124. The lifting mechanism is operably connected to a motor located inside the dispensing unit 125 (not shown).
The shown lifter 124 has a pump engagement portion 122 that partly encloses and in a form-fit manner engages the sliding sleeve 312 of the pump 300a. The engagement portion 122 has a substantially recessed surface portion 129 forming a lifter cavity being concave and forming a substantially hollow semicylinder extending in the vertical direction. An outwardly and laterally protruding flange 127 is formed at the upper end of the pump engagement portion 122, which flange forms a lifting shelf 127 for the actuating flange 314 of the sliding sleeve to rest on, also see
At the lower end of the pump engagement portion 122, there are provided two flexible arms 126a; 126b located at opposite sides of the lifter 124 and extending towards the front. These allow for an annular-like snap-fit engagement between the lifter 124 and the sliding sleeve 312 inserted into the lifter cavity 129. During the insertion of the sliding sleeve 312 into the lifter cavity 129, the arms 126a; 126b are moved sideward from their rest (equilibrium) positions and exert spring forces to the sleeve 312. The fully inserted sleeve 312 is resiliently kept in place by the arms partly enclosing the sleeve forming a cylinder snap-fit connection with the arms 126a; 126b, see

The fluid dispensing system 1 has so far been described in view of using the dispenser 100 together with the fluid container 200 having a pump 300a of the first type. It is desirable to be able to use the fluid container 200 with a pump 300b of the second type in the dispenser 100 described above without affecting the possibility of still being able to load the dispenser 100 with a fluid container 200 having a pump 300a of the first type. A removable adaptor assembly according to the present disclosure provides this possibility. In the following, the fluid dispensing system 1, the dispenser 100 and the adaptor assembly will be exemplified in more detail by reference to enclosed drawings and a number of exemplary embodiments.
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 300b. 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 fluid container, when the chamber is not squeezed. Similarly, a valve may be arranged between the chamber 300b 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 a pump 300b of a flexible or resilient pump chamber of other shapes than an elongated and elastic tube chamber 300b.
The adaptor assembly 400 comprises an upper part 410 forming a fluid container 410 of the present disclosure for removably connecting the adaptor assembly to the fluid dispensing system 1 and the fluid container 200.
The adaptor assembly 400 also comprises two actuation parts 420a; 420b, each comprising a portion 126a; 126b forming an actuation head 126a; 126b that is movable between a non-actuated position and a fully actuated position, so that the elongated and elastic pump chamber 300b can be laterally compressed between the two actuation heads 126a; 126b, when the adaptor assembly 400 and the fluid container are mounted in the dispenser, thereby causing fluid to be dispensed from the fluid container 200.
The adaptor assembly 400 further comprises a lower part 430 forming a moving part 430 of the present disclosure that is configured to engage the pump engagement portion 122 of the lifter 124 and to partly enclose the pump 300b of the second type.
A laterally protruding flange 413 is provided at the lower end of the fluid container support 410, which flange protrudes outwardly from the lower end of the cap receiving portion 411.

Each front terminal end of the U-shaped element forming the cap receiving portion 411 turns and projects in a sideward direction to form a positioning means in the form of a positioning flange 415a; 415b that connects to and extends along the width of the front end of the laterally protruding flange 413. These positioning flanges 415a; 415b match the shapes and dimensions of outer front side edge portions the flange engagement portion 134 that form the connecting portions for the positioning means 415a; 415b. Thus, the positioning flanges 415a; 415b provide a proper insertion of the adaptor assembly 400 into the dispensing unit 125. The flanges 415a; 415b may also prevent the lateral, rotational and/or axial movement of the cap receiving portion 411 mounted in the dispensing unit 125.
At the rear lower portion of the cap receiving portion 411 there is optionally provided a pump supporting element 418 in the form of a supporting flange 418 laterally extending into the opening 412 and having concave portion 419 that in form matches the elongated and elastic tube chamber 300b shown in
A cap supporting rib 414 extends laterally from and partly along the U-shaped inner surface 416 of the cap receiving portion 411. This cap supporting rib 414 may provide some rigidity to the fluid container support and is configured to partly engage or support the circular shape of the connector cap 360 of the fluid container 200 of
The skilled person appreciates that the fluid container support 410 may adopt other shapes than the U-shaped one, including but not limited to a polygonal shape that still may form the support for fluid container 200 and the connector cap 360 or the like and form an engagement with U-shaped cavity portion 134 forming the locating flange engagement portion 134 of the dispensing unit 125.
In an upper portion of the cap receiving portion 411 and the wall thereof, there is provided a recess in which there is provided an elastic and flexible switch displacing arm 417 extending from a rear portion of the wall 416 towards the front. The switch displacing arm 417 is laterally movable from a rest position to towards a switch-actuated position. The function will be explored in more detail below, see
The adaptor assembly 400 further comprises the two actuation parts 420a; 420b as shown in
Each first end 424a; 424b is connected to the fluid container support 410 at the lower end of the U-shaped inner surface 416 at a straight surface portion 411a; 411b formed by a straight pointing arm 411a; 411b of the U-shaped element 411. Thus, the elongated arms 422a; 422b are connected to the straight pointing arms 411a; 411b of the fluid container support 410 at opposite sides of the central opening 412 and extend from their first ends 424a; 424b in a direction (L1; L2) downwards and towards each other to their second ends 423a; 423b.
Each second end 423a,423b of the arms carries an actuation head 426a; 426b that comprises a first contact surface 427a; 427b and a second contact surface 428a; 428b. Each first contact surface 428a; 428b is configured for abutting against a dolly surface 436a; 436b formed by a sliding surface of the moving part 430 as described hereinbelow. Each second contact surface 428a; 428b is configured to abut against the pump 300b of the second type. The actuation heads 426 projects slightly outwardly in two opposing directions being substantially perpendicular directions to the longitudinal direction (L1) of the elongated arm 422 to form the first and second contact surfaces 427a; 427b; 428a; 428b facing away from each other. Each shown second contact surface 428a; 428b is convex in its shape to allow a smooth and proper contact with the pump 300b. The second contact surfaces 428a; 428b face each other to allow the surfaces to abut against the pump 300b of the second type on opposite sides thereof, see
As shown in
The actuation heads 426a; 426b are both movable between their non-actuated positions and fully actuated positions to allow a pump 300b of the first type to be compressed between the two actuation heads 426a; 426b causing fluid to be dispensed from the pump 300b, when the adaptor assembly 400 is mounted in the dispenser 100 together with the fluid container 200 and upon actuation of the dispensing operation.
The movements of the actuation heads 426a; 426b can be realized by movably connect the first ends 424a; 424b of the arms to the fluid container support 410 and/or by making at least a portion of the arm flexible or elastic. Thus, the actuation heads 426a; 426a2 can be moved along rotational directions Z1; Z2 between non-actuated positions and fully actuated positions, see
The movable connections of the arms 422a; 422b to the fluid container support 410 can be provided by the arms 422a; 422b being pivotally connected to the fluid container support 410. The skilled person also appreciates that other types of movable connections may be used, including but not limited to a pivot formed by hinge connection or by a living hinge.

In the shown embodiment, the arms 422a; 422b are movably connected to a rear portion of the adaptor assembly 400, wherein the arms 422a; 422b are connected to a hinge 470 with a pivot 471 about which the arm can be moved along rotational directions X1; X2 see
The skilled person also appreciates that other types of movable connections may be used for providing the movements of the actuation heads 426a; 426b. For example, the skilled person appreciates that it can be realized by movably connect the first ends 424a; 424b of the arms 422a; 422b to the adaptor assembly 400 by a living hinge or the like, and/or by making at least a portion of the arm flexible or elastic as has been described hereinabove.
The adaptor assembly 400 further comprises the lower part 430 forming the moving part 430 of the present disclosure that is configured to engage the pump engagement portion 122 of lifter 124 and to partly enclose the pump 300b of the second type.
As set forth in
The shapes and dimensions of the moving part 430 are configured to be partly enclosed and engaged by the lifter 124 of the dispenser 100. The skilled person appreciates that the moving part 430 may adopt any suitable shape and dimensions for engaging the lifter 124 as described hereinabove.
The moving part 430 is movably connected to the fluid container support 410. In the central through-opening 432 of the moving part 430 on opposite side portions thereof between the front portion and the rear wall are the dolly portions 462a; 462b presenting dolly surfaces 436a; 436b facing substantially each other and the through-opening 432. The dolly surfaces 436a; 436b extend with oblique angles downwards and inwards in directions towards each other to form a tapering cavity portion therebetween, see
According to the disclosure, suitable materials for forming the adaptor assembly 400 may be aluminum or any suitable plastics such as polyoxymethylene (POM), polyamide 12 (PA 12) and olefin plastics, e.g. polyethylene or polypropylene. The adaptor assembly 400 may be formed by injection molding, 3D printing or any other suitable method known to the skilled person. The mentioned materials and forming of the assembly can be used for all parts of the adaptor assembly and a combination of the materials may also be considered for adaptor assembly or parts thereof.

As shown in
The adaptor assembly 400 may also be modified to adjust the position it has in relation to the pump 300b as well as to the shape of the pump 300b and the maximum volume desired to be dispensed from the fluid container 200 as described in relation to
As also shown in
Once the lifter 124 is in its uppermost position, the lifter 124 and moving part 430 moves downwards to the positions they had before the user's hand was identified to actuate the dispensing of fluid. The actuation heads 426a; 426b are then returned to their non-actuated positions, when refilling of the pumping chamber occurs by the provision of a filling force being provided, inter alia, by, inter alia, the inherent resilience of the wall of the pumping chamber 300b (not shown).
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 400 may adopt other shapes than the ones shown in the drawings, e.g. the adaptor assembly 400 may easily be modified to be used a manually actuated dispenser, e.g. as the one described in WO2011/133085. Furthermore, the skilled person also appreciates that the moving part 430 and the fluid container support 410 could adopt a circular sleeve form to provide an adaptor assembly 400 having similar outer shapes and dimensions as pump 300a of the first type of
Furthermore, any actuation part 420 may comprise an actuation part 420a; 420b with an actuation head 426a; 426b in the form of a cam wheel having a contact surface portion forming the first contact surface and another contact surface portion forming the second contact surface 428a; 428b carrying the protruding part of the cam wheel. The dolly surface (-s) 436a; 436b of the moving part 430 may in this case be a vertical inner surface that is in contact with the cam wheel, wherein a displacement of the moving part 430 upwards causes the dolly surface 436a; 436b to rotate the cam wheel so that the protruding part of the cam wheel compresses the pump 300b of the second type. The skilled person appreciates that the adaptor assembly 400 of this embodiment may comprise one or more additional cam wheels.
The second contact surface (-s) of the actuation head (-s) according to the disclosure may be made of soft and flexible material for a soft fluid dispensing operation.
The actuation part as described herein may also be used together with a fixed dolly forming part of the adaptor assembly 400. In this configuration, the pump of the second type can be positioned between the second contact surface of the actuation part and the fixed dolly, the latter replacing the need of two actuation parts 420a; 420b. When a force is applied to the actuation part to move the actuation head towards the pump, the pump is compressed between the second contact surface of the actuation head and the dolly surface 436a; 436b causing fluid to be dispensed from the pump.
Furthermore, it may be provided a dispenser 100 with the dispensing mechanism that allows the connecting support to be non-integrated or integrated part of the dispenser 100 and at the same time providing all the advantages with the use of the first connecting support, the actuation parts 420a; 420b described herein. Such dispensing mechanism may be fixedly attached via a connecting support being similar to the first fluid container support 410 and/or a lifter adopting the shape of the moving part 430.
