[0003] Pump system for pumping a flowable and pumpable medium, dispenser unit with a pump system and a wall bracket

[0004] State of the art

[0005] The present invention relates to a pumping system for pumping a free-flowing and pumpable medium, comprising a cardboard container, an adapter, and a pumping device. The invention further relates to a dispenser device with such a pumping system and a wall bracket.

[0006] Cardboard packaging is used particularly for packaging liquid goods, such as liquid foodstuffs. Such packaging is known, for example, from EP 3 145696 B1.

[0007] Furthermore, cardboard packaging or containers are used for packaging non-food products that can be poured freely, such as hand soap, mouthwash, shampoo, shower gel, laundry detergent, fabric softener, dish soap, or cleaning agents. With these non-food products, there is often a need to remove smaller quantities from the packaging, for example, a small amount of hand soap for washing hands.

[0008] Disclosure of the invention

[0009] Based on this state of the art, the task is to enable the metered dispensing of flowable products from a cardboard container.

[0010] To solve this problem, a pumping system for pumping a free-flowing and pumpable medium is provided, comprising a cardboard container for receiving the medium, an adapter for attaching it to the cardboard container, and a pumping device connected to the adapter for pumping the medium, wherein the adapter is positively and / or force-fit connected to the cardboard container. The pumping system according to the invention includes a cardboard container for receiving the medium, in particular non-food products. This advantageously expands the conventional application range of cardboard packaging, especially with regard to sustainability and resource conservation. Furthermore, the pumping system has an adapter for attaching it to the cardboard container and a pumping device connected to the adapter for pumping the medium. The adapter enables precise positioning on the cardboard container.According to the invention, the adapter is connected to the cardboard container by a form-fit and / or force-fit connection, wherein the connection is particularly designed to be detachable. The form-fit and / or force-fit connection of the adapter to the cardboard container ensures a secure fit of the adapter on the cardboard container, thus preventing unintentional detachment of the adapter during the metered removal of the non-food item from the cardboard container.

[0011] According to a preferred embodiment of the invention, the cardboard container is a gable-roof package with two roof surfaces, and the adapter is detachably connected to the cardboard container by means of a connecting element. The adapter can be hinged or foldable, for example, by means of two, three, four, etc., sections that are movable or foldable relative to one another. The hinge or foldability makes it easier to connect the adapter to the cardboard container. For example, individual sections of the adapter can be folded, twisted, pressed, or inserted into undercuts or behind protruding projections to create a connection with the cardboard container. The connecting element can be designed as a projection, elongated, bolt- or pin-like, wing-like, or the like. Preferably, there are several connecting elements. In particular, connecting elements can be designed in pairs.For example, two connecting elements can be attached to or fixed to the cardboard container on two opposite sides or surfaces. Alternatively, the connecting element can be designed as a rib on the inside of the adapter. The rib can cut into an edge of a gable roof surface, thereby creating a fastening. Alternatively, the rib can have a recess to accommodate an edge of a gable roof surface of the cardboard container.

[0012] The adapter is preferably flexible. A flexible adapter offers the advantage of being detachable from the cardboard container, particularly by manually deforming the adapter, which breaks the connection between the connecting element and the cardboard container.

[0013] In an advantageous embodiment of the invention, the cardboard container is a flat-roof or sloping-roof package comprising a flat roof, a first side surface, and a second side surface. The first and second side surfaces are preferably arranged parallel to each other. Extending from the flat roof, a first flap is folded towards and connected to the first side surface, and a second flap is folded towards and connected to the second side surface. The adapter is positively and / or force-fit connected to the first and second flaps. The first and second flaps can be triangular or wing-shaped and each have a free surface and a connecting or adhesive surface.At each transition from the open area to the connecting surface, two transition edges, a first transition edge and a second transition edge, can be formed for each tab. The transition edges can be straight and coplanar, with the first and second transition edges of a tab preferably forming an angle between 50° and 150°. Due to the cardboard material of the cardboard container, a gap is formed between the open area and the connecting surface. In other words, the first and second tabs each have a first and second thickness. Thus, the transition edges have a width. In other words, the transition edges can be formed as projections. In this respect, the adapter—or rather, theOne or more connecting elements formed on the adapter – in particular with the transition edges of the first and / or second tab – interact mechanically, thus creating a positive and / or non-positive connection between the adapter and the cardboard container. The first and second side surfaces of the cardboard container are preferably flat and parallel to each other. Alternatively, the side surfaces can be curved or each have several sections, with the multiple sections arranged in different planes and, in particular, separated from each other by folds.

[0014] Preferably, the cardboard container has a roof that tapers towards an opening, in particular a pyramidal or dome-shaped roof.

[0015] According to a preferred embodiment of the invention, the cardboard container has an opening, and the adapter has a connecting element that geometrically corresponds to the opening and can be pressed into it. Because the connecting element is geometrically corresponding to the opening and can be pressed into it, a good seal between the adapter and the cardboard container is achieved. This eliminates or at least reduces the risk of medium loss. Furthermore, pressing the connecting element into the opening allows for easy and precise positioning of the adapter relative to the cardboard container. For a good seal, the connecting element can be made of a structurally compliant and / or flexible material—in particular, thick paper or cardboard, or a plastic such as an elastomer.Flexible materials, especially elastomers such as rubber, can better fill or penetrate recesses, threads, grooves, and the like formed in or on the opening, thus improving the sealing effect. The connecting element can be made of the same material as the adapter or of a different material.

[0016] In an advantageous embodiment of the invention, the opening has a circular contour and the connecting element is conical, the conical connecting element comprising a sealing element, in particular a disc- or ring-shaped one, wherein the sealing element can be arranged on the conical connecting element, or the conical connecting element is overmolded with the sealing element in a two-component injection molding process. Due to the conical shape and the insertion of the connecting element into the circular opening, the sealing effect between the adapter and the cardboard container can be optimized. Further optimization of the seal can be achieved by means of a separately designed sealing element arranged on the conical connecting element, e.g., as a soft component attached to it.Alternatively, for further optimization of the seal, the conical connecting element can be overmolded with the sealing element in a two-component injection molding process. The opening can have a stiffening element. In particular, the stiffening element can include a thread, preferably an external thread.

[0017] To achieve a good and / or improved seal between the adapter and the cardboard container, it is also conceivable that the connecting element is tubular and / or bellows-shaped and pressed against a surface of the cardboard container surrounding the opening. A combination of such a bellows-shaped connecting element with a conical connecting element, i.e., a two-part connecting element, is also conceivable. It is also conceivable that the connecting element has a thread and is screwed to the stiffening element.

[0018] An advantageous embodiment of the invention provides that the opening has a circular contour and a stiffening element is formed at the opening, wherein the connecting element and the stiffening element are designed such that, in a state where the connecting element is pressed into the opening, the connecting element and / or the stiffening element is deformed compared to a state where the connecting element is not pressed into the opening. Such deformation enables a good seal. The stiffening element may have a thread. A cap may be screwed onto the thread.

[0019] A preferred embodiment of the invention provides that the adapter rests flat on the cardboard container. This flat contact allows for a more even distribution of force on the cardboard container, which is advantageous for the dimensional stability of both the adapter and the container. In particular, forces transmitted by the pumping device can be advantageously distributed to the cardboard container via the adapter. For the best possible form-fit and / or force-fit connection between the adapter and the cardboard container, the adapter can have several individual surfaces. These individual surfaces of the adapter preferably rest on a plurality of surface sections of the cardboard container, for example, on one or more surface sections of the roof – such as the two roof surfaces of the gable roof – and / or on one or more side surfaces of the cardboard container.The connection is designed to be as free of play as possible, so that detaching the adapter from the cardboard container or breaking the connection between the adapter and the cardboard container preferably requires force and / or deformation of the adapter. Furthermore, the adapter may have stiffening elements, in particular stiffening ribs, for improved dimensional stability.

[0020] Preferably, the adapter has a base element and a cover.

[0021] Preferably, the hood can be connected to the base element by a form-fit and / or force-fit connection and can be detached from the base element without damage. In other words, the adapter can be made in two parts. Preferably, the hood has two guide rails, each arranged on two opposing inner walls of the hood. The hood can be guided more easily by means of two guide rails. For example, the hood is cup-shaped, with a variety of possible inner contours. For example, the inner contour – in a cross-section perpendicular to the sides of the hood – can be square or rectangular. It is also conceivable that the adapter, i.e., the base element and the hood, are made in one piece. Furthermore, the hood and the base element can be connected by means of the pumping device. By pressing on the hood from the outside, a pump stroke can be triggered and the medium pumped out.The hood can be configured so that the pump mechanism is concealed. Furthermore, the pumping process is very simple and quick, requiring only the elbow. The hood can also include a nozzle for pumping out the medium. The hood's base can have a smooth surface, which facilitates easy cleaning. This is particularly advantageous with regard to hygiene requirements, for example, in sterile environments such as operating rooms, or in the food service industry.

[0022] An advantageous embodiment of the invention provides that the base element has at least one projecting, in particular rib-shaped, connecting element, wherein the connecting element can snap into or hook into the hood. Preferably, the adapter has several connecting elements arranged parallel to one another and having a flat surface. For example, the connecting elements of the adapter can be inserted, slid, or pressed into grooves formed in the hood, wherein the thickness of each connecting element is greater than the width of the grooves. Alternatively, the connecting elements can be inserted, slid, or pressed between two hood projections, wherein the thickness of each connecting element is greater than the distance between the two hood projections. Preferably, the grooves or the hood projections are formed on an inner surface of a hood lid.Preferably, the connecting elements are arranged on a surface of the adapter facing away from the cardboard container. Functionally, the connecting elements can also act as stiffening elements of the adapter, thereby increasing its dimensional stability.

[0023] According to a preferred embodiment of the invention, the adapter, in particular the base element, has an adapter groove for positioning and securing the adapter to the cardboard container, wherein, in particular, a sealing fin of the cardboard container can be inserted into the adapter groove. The width of the adapter groove can, in particular, be smaller than the thickness of the sealing fin. The adapter, i.e., the base element and the cover, and the pump device can be made of different materials. The suitable materials are not limited and can include wood, plastic, biopolymers, glass, fiber composites, and recycled materials from the production of beverage or compound cartons. Manufacturing from metallic materials is also conceivable.

[0024] An advantageous embodiment of the invention provides for a multi-part, length-variable hood, wherein the hood is particularly telescopically designed. In other words, the hood can have several sections that are translationally movable relative to one another along an axis. As an alternative to a multi-part telescopic structure, the hood can be designed as a single piece, but made of a soft material and / or have a collapsible and length-variable structure. For example, the hood can be designed as a bellows or a coil spring. In this way, the hood can advantageously be collapsed to a desired size or length, or it can spring back automatically according to the height of the cardboard container and / or when pressure is applied to the pumping device.

[0025] Preferably, the connecting element for connecting the adapter to the cardboard container is formed on the base element or on the hood.

[0026] In a preferred embodiment of the invention, it is provided that the adapter, in particular the hood, has a release element, preferably two release elements, wherein the at least one release element is formed separately or integrally with the adapter.

[0027] A further object of the invention is a dispenser device comprising a pump system according to one of the preceding embodiments and a wall bracket, wherein the wall bracket has a spring plate pivotable about a hinge, wherein a spring is arranged on a first side of the spring plate which loads the spring plate in a first direction with a first force, wherein the cardboard container is arranged on a second side of the spring plate facing away from the first side, which loads the spring plate in a second direction opposite to the first direction with a second force, wherein the wall bracket is configured such that the second force is reduced in the course of emptying the cardboard container, and wherein when the second force falls below the first force, the spring plate is gradually pivoted in the first direction.The terms "first" and "second" in the context of the invention can refer to both longitudinal and rotational directions. Furthermore, the spring can be a torsion spring, tension spring, or compression spring. It is also conceivable that several springs are arranged on the first side of the spring plate. The wall bracket preferably has an anchor that can be securely mounted to a wall, wherein the anchor can be screwed or glued to the wall. It is also conceivable that the anchor is both screwed and glued to the wall. Furthermore, the wall bracket preferably has a wall plate connected to the wall, particularly by means of the anchor. The wall bracket also includes a base plate, which is preferably perpendicular to the wall plate, and which may have a section arranged parallel to the wall plate.Furthermore, the wall bracket can be configured such that the pump system is pivotally connected to it. Therefore, it is possible for the pump system to be tilted relative to the wall plate, particularly for replacing or refilling the cardboard container. In addition, the wall bracket can have a locking mechanism to facilitate the replacement or refilling of the cardboard container.

[0028] According to an advantageous embodiment of the invention, the adapter has a base element and a hood, wherein the hood has a base body and a hood opening, and wherein the hood further has a viewing window on a side facing the hood opening, or a recess on an edge formed on the hood opening for indicating the fill level of the cardboard container.

[0029] An advantageous embodiment of the invention provides a magnetic and / or electronic component for measuring the weight of the cardboard container.

[0053] Embodiments of the invention

[0054] In the various figures, identical parts are always marked with the same reference symbols and are therefore usually only named or mentioned once.

[0055] Figure 1 schematically shows a first embodiment of a pump system 1 according to the invention in a perspective exploded view. The pump system 1 is configured for pumping and dispensing a free-flowing and pumpable medium. The pump system 1 includes a cardboard container 3 for receiving the medium. The pump system 1 also includes an adapter 5 for attaching to the cardboard container 3. Furthermore, the pump system 1 comprises a pumping device 7 connected to the adapter 5 for pumping the medium. According to the invention, the adapter 5 is positively and / or non-positively connected to the cardboard container 3. Different positive- and / or non-positive connections between the adapter 5 and the cardboard container 3 are shown in other figures and explained in the corresponding descriptions.

[0056] The adapter 5 comprises a base element 51 and a hood 52, shown in half-section. The adapter 5 also has a dispensing spout 53. The hood 52 is positively and non-positively connected to the base element 51. For this positive and non-positive connection, the base element 51 includes four connecting elements 511, which project in a rib-like or plate-like manner from a surface of the base element 51 facing away from the cardboard container. The hood 52 has four grooves in a hood top 522 that correspond to the connecting elements 511, although the grooves are not visible in Fig. 1. The connecting elements 511 can snap into or hook into the grooves. For this purpose, each connecting element 511 has a thickness greater than the respective width of the grooves. Furthermore, the base element 51 has seven stiffening elements 512.Functionally, both the four connecting elements 511 and the seven stiffening elements 512 are designed as stiffening means and thus increase the dimensional stability of the base element 51, especially during pumping of the medium. However, the number of stiffening elements 512 and connecting elements 511 is not absolutely fixed and can vary depending on requirements.

[0057] The adapter 5, or base element 51, lies, at least partially, flat on a roof surface 31 of the cardboard container 3. This flat contact allows forces applied during pumping to be distributed more evenly across the cardboard container 3. The cardboard container 3, according to the first embodiment of a pumping system 1 shown schematically in Fig. 1, is designed as a gable-roof package. In this respect, the cardboard container 3 has a roof 33 designed as a gable roof with two roof surfaces 31. Furthermore, the gable-roof package has a sealing fin 32. An adapter groove 513 of the base element 51 is pushed or pressed onto the sealing fin 32 to create a positive and non-positive connection between the adapter 5 and the cardboard container 3. As a result of the physical contact, or...The mechanical interaction between the adapter groove 513 and the sealing fin 32 also allows the adapter 5 to be optimally positioned on the cardboard container 3.

[0058] Fig. 2 schematically shows the first embodiment of the pump system 1 according to the invention from Fig. 1 in a perspective view. Fig. 2 shows the base element 51, the hood 52, and the dispensing spout 53 in a sectional view. The sealing fin 32 is arranged in the adapter groove 513. The hood 52 extends almost completely to a support surface of the cardboard container 3.

[0059] Fig. 3 schematically shows a second embodiment of a pump system 1 according to the invention in a perspective exploded view. The hood 52 of the second embodiment is significantly shorter compared to the first embodiment. Two connecting elements V are formed on each of two opposing and parallel side walls S1, S2 of the hood 52. The four connecting elements V are each designed as projections and extend into the interior of the hood. The cardboard container 3 also has an opening 38 with a circular contour. A further stiffening element 39 is formed at the opening 38, which enables a mechanical connection of the adapter 5 or the base element 51 with the cardboard container 3. Contents contained in the cardboard container 3 can be removed or emptied via the opening 38.to be pumped, for example a non-food item, in particular hand soap, mouthwash, shampoo, shower gel, laundry detergent, fabric softener, dishwashing liquid or cleaning agent.

[0060] Figure 4 schematically shows a detailed perspective view of the second embodiment from Figure 3. The hood 52 is shown in a partial sectional view in Figure 4. The four connecting elements V are integrally formed with the hood 52. Two connecting elements V of each side wall S1, S2 extend straight and parallel to the corresponding side wall S1, S2. In other words, the connecting elements V are all elongated. Connecting elements V can also be formed in segments or at points. The two connecting elements V of each side wall S1, S2 are arranged under the roof 33 of the gable-roof packaging or extend under the roof 33. The connecting elements V create at least a positive-locking connection between the adapter 5 and the cardboard container 3.

[0061] Figure 5 schematically shows a third embodiment of the pump system 1 according to the invention in a perspective view. The third embodiment differs from the second embodiment shown in Figures 3 and 4, particularly with regard to the connecting elements V. Two connecting elements V are formed on the inside of each of the side walls S1 and S2, projecting into the interior of the housing. Each connecting element V is designed as a projection and has the form of a short pin or bolt, which tapers to a point.

[0062] Figure 6 schematically shows a fourth embodiment of the pump system 1 according to the invention in a perspective view. The hood covers 522 of the hoods 52 shown in Figures 1 to 5 have at least one curvature. The hood 52 according to the fourth embodiment shown in Figure 6 is flat. The cardboard container 3 according to the fourth embodiment is also flat, as will be explained in more detail in the description of Figure 7. The hood 52 has a release element 524 on each of two parallel and opposite side walls S1, S2 of the hood 52. The two release elements 524 are formed integrally with the hood 52. However, release elements can also be mounted separately and then made of an alternative material that differs from the material of the hood and has a special spring effect or holding force.To release the cover 52 from the cardboard container 3, the release elements 524 can be actuated at each edge K of the release elements 524 facing away from the cover ceiling 522 in the direction indicated by the dashed arrows, i.e., pulled away from the cardboard container 3. The exact release of the connection between the cover 52 and the cardboard container 3 is explained in the description of Fig. 7.

[0063] Figure 7 schematically shows a detailed perspective view of the fourth embodiment from Figure 6. The hood 52 is shown in a sectional view. A connecting element V is formed on an inner side of the first side wall S1 of the hood 52. The same connecting element V is also formed on an inner side of the second side wall S2 (not visible in Figure 7). The cardboard container 3 is designed as a flat-roof package and has a flat-roofed roof 33, a first side surface FL1, and a second side surface FL2 (not visible in Figure 7). The first side surface FL1 and the second side surface FL2 are arranged parallel to each other, with a first flap L1 extending from the flat roof 33 and folded towards and connected to the first side surface FL1, and a second flap L2 (not visible in Figure 7) folded towards and connected to the second side surface FL2.The adapter 5 or the hood 52 is positively and force-fit connected to the first tab L1 and the second tab L2 by means of the two connecting elements V. The first tab L1 and the second tab L2 are wing-shaped. Furthermore, the two connecting elements V are arranged parallel to the flat roof 33.

[0064] Figure 8 schematically shows a fifth embodiment of the pump system according to the invention in a perspective view. This fifth embodiment has three connecting elements V on each of the two side surfaces S1, S2 of the hood 52. The wing-like tabs L1, L2 of the cardboard container each comprise two side edges K1, K2 and one end edge Ke. The connecting elements V rest on either a side edge K1, K2 or an end edge Ke. This prevents the hood 52 from unintentionally detaching from the cardboard container.

[0065] Figure 9 schematically shows a sixth embodiment of the pump system according to the invention in a perspective view. Figure 10 schematically shows the sixth embodiment of the pump system 1 according to the invention in a perspective sectional view. The release element 524 according to the sixth embodiment is designed to be movable about the axis A shown with dashed lines. In contrast to the fourth embodiment shown in Figures 6 and 7, the sixth embodiment has a further edge Kw on a side of the release element 524 facing away from edge K. As in the embodiment shown in Figure 9, the further edge Kw can be understood as a wall opening that makes it possible to pivot the release element 524 outwards into a release position by pressing a finger on the segment formed above the axis A and, consequently, the segment formed below the axis A.

[0066] Figure 11 schematically shows a seventh embodiment of the pump system 1 according to the invention in a perspective sectional view. The cardboard container 3 according to the seventh embodiment is a gable-roof package having a gable roof 33 with two roof surfaces 31, wherein the adapter 5 or the hood 52 has a connecting element V on each side wall S1, S2, the connecting elements V being shown in a locking position in Figure 11, in which the connecting elements V engage under the roof surfaces 31 of the gable roof 33, so that the adapter 5 is fixed to the gable roof 33. The release elements 524 each include a gripping recess G for gripping and releasing the release elements 524. By means of the gripping recesses G, the release elements 524 can thus move from the locking position to a release position in order to detach the hood 52 and, consequently, the adapter 5 from the cardboard container 3.

[0067] Fig. 12 schematically shows an eighth embodiment of the pump system 1 according to the invention in a perspective sectional view. The eighth embodiment differs from the seventh embodiment shown in Fig. 11 by the release elements 524, whereby only one of the two release elements 524 is visible in Fig. 12. In the eighth embodiment, the transition from the detent position to the release position is effected by pressing in the two directions indicated by the dashed arrows.

[0068] Fig. 13 schematically shows a first embodiment of a dispenser 100 according to the invention, wherein the dispenser 100 comprises a pump system 1 and a wall bracket 200. Fig. 14 schematically shows the dispenser 100 from Fig. 13 in a perspective exploded view. The wall bracket 200 comprises a spring plate 204 that can be pivoted about a hinge 202. A spring 206 is arranged on a first side of the spring plate 204, which, according to Fig. 14, is the underside of the spring plate 204, and which loads the spring plate 204 with a first force in a first direction. In Fig. 14, the first direction corresponds to an upward direction or a direction of rotation that pivots the spring plate 204 upwards.On a second side of the spring plate 204 (a top side of the spring plate 204), opposite the first side, the cardboard container 3 is positioned, which exerts a second force on the spring plate 204 in a direction opposite to the first. As the cardboard container 3 empties during use of the medium, the second force gradually decreases. When the second force falls below the first force, the spring plate 204 is gradually lifted, i.e., pivoted upwards in the first direction. It is also conceivable that an embodiment does not have a spring plate 204, with the spring 206 exerting the first force directly on a bottom side of the cardboard container 3. The clip-shaped spring 206, visible in Figures 13 and 14, could directly lift the gradually emptying package and, with appropriate shaping, e.g.,Extended in a bow shape to a front edge of the cardboard container 3, serving as a fill level indicator 212, analogous to the previously described base plate 208.

[0069] The wall bracket 200 further comprises a base plate 208 and a wall plate 210, wherein the base plate 208 and the wall plate 210 are formed in one piece and arranged perpendicular to each other. The wall plate 210 can be screwed to a wall using the mounting holes shown in Fig. 14. Alternatively, the wall plate can be glued to the wall.

[0070] To indicate that the cardboard container 3 is largely emptied or already empty, the base plate 208 has a fill level indicator 212 on a front edge, which can be designed, for example, as a dark line or a colored marking. Furthermore, the wall bracket 200 includes a locking spring 214 by means of which the cover 52 – and with it the entire pump system 1 – can be connected to the wall bracket 200. For this purpose, the locking spring 214 has two detent elements 214' which can mechanically interact with the cover 52 on its rear side to enable the cover 52 to be released from and connected to the wall bracket 200 (see, for example, Fig. 19). The cover 52 can be released from the wall bracket 200 by means of a release mechanism 216.

[0071] The hood 52 has a recess 54 on its underside (as shown in Fig. 14) for indicating the fill level of the cardboard container 3. When the cardboard container 3 is largely empty or already empty, the fill level indicator 212 can be seen through the recess. Fig. 15 schematically shows the dispenser 100 from Figures 13 and 14, where an empty fill level of a cardboard container 3 can be seen by means of a recess 54 and a fill level indicator 212.

[0072] Fig. 16 shows a detailed view of the first embodiment of the dispenser device 100 from Figures 13 to 15. The hood 52 has two guide rails F, by means of which the hood 52 - in interaction with two counter-rails F' - can be guided over the base plate 208.

[0073] Fig. 17 schematically shows a second embodiment of the dispenser device 100 according to the invention, comprising a pump system 1 and a wall bracket 200. The hood 52 has a viewing window 56, through which the empty state of the cardboard container 3 can be seen. Fig. 18 schematically shows the dispenser device 100 from Fig. 16 in a perspective exploded view. In contrast to the first embodiment of the dispenser device 100, the second embodiment has a mounting plate 211, wherein the locking spring 214 and the mounting plate 211 are formed as a single unit. The base plate 208 also includes a locking structure 218, which can interact with the locking spring 214. The locking structure 218 allows the base plate 208 to be locked at different heights, thus enabling different package sizes to be combined with the same wall bracket 200. By means of an anchor 215, which is shown in the Fig.Since 14 is not visible, the mounting and positioning of the dispenser unit 100 on a wall can be simplified.

[0074] Fig. 19 schematically shows a third embodiment of the dispenser device 100 according to the invention in a side view for a full cardboard container 3. The hood 52 is shown in a partial sectional view. Due to the sufficiently large weight of the cardboard container 3, the spring plate 204 is arranged parallel to the base plate 208 – despite the initial upward force exerted by the spring 206. The fill level indicator 212 is therefore not visible in the viewing window 56. Consequently, a user is not encouraged to change or refill the cardboard container 3.

[0075] Fig. 20 schematically shows the third embodiment of the dispenser device 100 according to the invention from Fig. 19 in a side view for an empty cardboard container 3. The hood 52 is shown in a full-section view. Due to the empty cardboard container 3 – i.e., due to insufficient downward force exerted by the cardboard container 3 on the spring plate 204 – the spring 206 pushes the spring plate 204 upwards. The base plate 208 and the spring plate 204 are therefore no longer parallel to each other. Rather, an angle (of approximately 10°) is formed between the base plate 208 and the spring plate 204. Consequently, the base plate 208 rests on the guide rail F. In other words, the hood 52 has moved upwards relative to the wall bracket 200 (as shown in Fig. 20). This means that the fill level indicator 212 can be seen in the viewing window 56.Users of dispenser device 100 are therefore advised to change or refill the cardboard container 3. Here too, the spring plate 204 could potentially be omitted if the spring 206 takes over this function and is adapted accordingly.

[0076] Figures 21 and 22 show a ninth embodiment of a pump system 1 according to the invention. In this embodiment, the cardboard container 3 has an opening 38 with a circular contour. A stiffening element 39 is formed at the opening 38. The stiffening element 39 is designed as a spout and has a thread to which a cap can optionally be attached to close the spout. A connecting element 8 is provided on the adapter 5, which can be pressed into the opening 38 of the cardboard container 3. The connecting element 8 and the stiffening element 39 are designed such that, in a state in which the connecting element 8 is pressed into the opening 38, the connecting element 8 and / or the stiffening element 39 are deformed compared to a state in which the connecting element 8 is not pressed into the opening 38. The illustrations in Figures 21 and 22 show the following:Figures 21 and 22 both show the state in which the connecting element 8 is pressed into the opening 38. The lower end of the connecting element 8 is deformed by the pressing and lies abutting the stiffening element 39.

[0077] Figure 23 shows a tenth embodiment of a pump system 1 according to the invention. Connecting elements V are provided on the adapter 5 of the pump system 1, which are designed to engage under the roof surfaces 31 of the gable roof 33 of the cardboard container 3 in a locking position, thus securing the adapter 5 to the gable roof 33. The connecting elements V are designed as ribs on an inner surface of the adapter 5. The ribs cut into the edges of the roof surfaces 31. (List of reference numerals)
