Description

Technical Field

[0001] The invention relates to a system for connecting a container to a dispensing device, a container for use in such a system and a receiving device for receiving such a container according to the preambles of the independent claims. Background Art

[0002] For a long time, there has been a need in society to save resources and use everyday items more than once. For this reason, refillable systems have been established on the market. In this case, valuable and stable containers are usually provided, in which liquids such as hand sanitizer can be contained. Such containers are usually provided with a device for dispensing the liquid, such as a pump dispenser or a spray dispenser.

[0003] To make the system reusable, the device for dispensing the liquid is removed from the container and a product corresponding to the original product is refilled into the container from a refill package, which is usually a bag made of film, which has significantly less material consumption than a reusable container.

[0004] During such refilling processes there is always a risk that the reusable container becomes contaminated and / or the user becomes soiled.

[0005] Dispensing devices are usually provided with a standpipe so that the product can be removed from the reusable container. Usually, liquid residues previously present in the reusable container always adhere to this standpipe. Therefore, here too there is a risk of soiling the user. In order to change the product, the entire dispensing device and the reusable container must be cleaned, which in some cases means considerable effort. Summary of the invention

[0006] The object of the present invention is therefore to remedy at least one or more disadvantages of the prior art. In particular, the object of the present invention is to provide a container and a system for connecting a container to a dispensing device which make it possible to reduce the use of material and in particular to reduce contamination during the refilling operation.

[0007] This object is achieved by the device defined in the independent claim. Further embodiments result from the dependent claims.

[0008] The system for connecting a container to a dispensing device according to the present invention comprises a base body arranged on the container and a connecting element arranged on the dispensing device. The connecting element is effectively connected or can be effectively connected to the base body. Mutually complementary engagement means are provided on the base body and the connecting element, so that when the engagement means engage with each other, a fluid-tight connection is generated between the base body and the connecting element.

[0009] The fluid-tight connection allows connecting the container to a dispensing device so that the product to be dispensed can be dispensed from the container by the dispensing device without spilling.

[0010] In this case, it can be provided that the system has a sealing element for producing a fluid-tight connection.The sealing element is preferably arranged to bear against the connecting element and the base body in a sealing manner.

[0011] The sealing element can easily be adapted to manufacturing tolerances.

[0012] The sealing element can be arranged on the base body. By being arranged on the base body, it is ensured that a new sealing element is used each time the container is replaced, thereby ensuring the sealing effect again and again.

[0013] Alternatively, the sealing element can be arranged on the connecting element. If the sealing element is designed appropriately, it can be used throughout the entire service life of the system. This saves costs on the one hand and resources on the other.

[0014] The sealing element can be configured as a surface seal. Such a seal is available as a semi-finished product, is easy to manufacture and has low production costs.

[0015] Alternatively, the sealing element can also be provided by a form fit or force fit, for example by engaging two conical elements (eg conical connectors) with each other in corresponding conical openings. The sealing effect can also be produced by pressing two sealing surfaces together.

[0016] The container can be constructed as a flexible container. Flexible containers are usually made of films that are welded together. Such flexible containers can be produced with extremely low material costs. This also results in low waste volumes. Since such flexible containers are only used in the form of refill bags, they do not require special requirements with regard to inherent strength and can therefore be manufactured accordingly in a material-saving manner.

[0017] Furthermore, the flexible container can be easily emptied after being connected to the dispensing device. Since the connection to the dispensing device is fluid-tight, the volume of the flexible container decreases as the product is dispensed, since no air is exchanged into the container. In other words, the container will collapse, so that the product can be dispensed substantially completely.

[0018] Optionally, the container can also be constructed as a dimensionally stable container. As a result of the design of a dimensionally stable container, a user can obtain a refill container that is easy to handle.

[0019] In this case, a standpipe may be provided in the dimensionally stable container.Since dimensionally stable containers are not compliant and flexible, in order to completely empty the container, product must be removed from the area at the bottom of the container.

[0020] In this case, it can be provided that the standpipe is constructed as a component of the container and is arranged integrally in the container.The standpipe is preferably connected to the base body.

[0021] Due to this configuration, contrary to the prior art, the standpipe does not need to be cleaned or removed from the reusable container after use, as it remains in the container.

[0022] The engagement means may be configured as a threaded connection.

[0023] The threaded connection allows a secure connection between the base body and the connecting element, which does not require further additional elements.

[0024] Alternatively, the engagement means may be configured as a sliding connection. The sliding connection allows the connecting element to slide transversely on the base. By definition, transverse sliding refers to sliding transversely to the longitudinal axis of the container. By definition, the longitudinal axis of the container is defined by the connection between the bottom of the container and the dispensing opening.

[0025] Alternatively, the engagement device can be configured as a plug connection. In this case, a plug connection is a connection that moves in the direction of the longitudinal axis. In other words, the engagement device can be designed in such a way that, for example, a connecting piece protrudes from the connecting element, which can be inserted into a corresponding opening in the base body. In this case, a sealing effect is produced between the outer surface of the connecting piece and the inner surface of the opening.

[0026] Alternatively, the engagement means may be configured as a bayonet connection. A bayonet connection is easy to operate and also allows a secure connection.

[0027] In all embodiments, a projection and / or a contraction formed on the engagement means for producing a snap connection may be provided. By providing a snap connection, accidental opening or loosening of the mutually engaged engagement means may be prevented to a certain extent. Furthermore, a tactile feedback may be provided to the user, so that the user is oriented by the secure connection of the substrate to the connecting element.

[0028] The base body may be non-detachably connectable to the container, in particular may be an integral component.

[0029] The non-detachable connection ensures that the container can be maneuvered easily and safely. Production as a single-piece component makes it possible to further reduce material costs.

[0030] The dispensing device can be configured as a metering device. Preferably, the dispensing device is configured as a pump dispenser or a spray dispenser. This corresponding design is advantageous for the user, because after engaging the device, the user can obtain an operable system.

[0031] The system may include a receiving device for receiving the container.

[0032] The receiving device can be designed to be responsive to the user accordingly. Furthermore, the receiving device can provide a container or a holding device which can receive a container, in particular as a refill container, with little material outlay. In other words, the receiving device can be designed for multiple uses and have corresponding stability. Therefore, the container described here no longer needs to meet high requirements for strength, because the forces generated can be absorbed by the receiving device.

[0033] It can be provided that the dispensing device is arranged on the receiving device. In particular, a part of the receiving device forms a component of the dispensing device.

[0034] Arranging the dispensing device on the receiving device allows providing a reusable dispensing device as part of a container or holding device which can receive a container as described above.

[0035] The receiving device may comprise in its interior an extension between the bottom of the receiving device and the connecting element of the dispensing device, which extension is shorter than the associated extension of the container, so that the container can be clamped in the receiving device. In this case, the container is clamped or can be clamped in the receiving device, in particular between the bottom of the receiving device and the connecting element. This makes it possible to exert a permanent prestress on the engagement device, so that it is pressed together.

[0036] For this reason, the receiving device can be made of two parts in particular. In this case, the first part of the receiving device is made together with the dispensing device, or these elements are arranged with each other.

[0037] This type of embodiment is particularly advantageous if the engagement device is designed as a plug connection. The container can be inserted into the receiving device and by connecting the receiving devices together, the plug connection can be brought into operative connection and the fluid-tight connection can be maintained by the clamping action.

[0038] Another aspect relates to a container, in particular for use in a system as described herein. The container has a base body for connection to a connecting element provided on a dispensing device. Engagement means are provided on the base body and can engage with complementary engagement means on the connecting element.

[0039] By providing complementary engagement means on the base body, the base body can easily be connected to, for example, a corresponding dispensing device.

[0040] The container can be configured as a flexible bag. The flexible bag can be made of very thin material, thereby reducing the impact on the environment by reducing material consumption. In addition, the flexible bag allows substantially complete discharge of the contents.

[0041] Alternatively, the container may be configured as a dimensionally stable container.

[0042] The dimensional stability enables the container to interact, for example, with a corresponding receiving device. In addition, a dimensionally stable container facilitates the user to manipulate the container.

[0043] In order to completely empty the container, a standpipe can be provided in the dimensionally stable container. This ends in particular in the bottom region of the dimensionally stable container.

[0044] The engagement means on the container can be configured as half of a threaded connection. Alternatively, the engagement means can be configured as half of a sliding connection. In another alternative, the engagement means can be configured as half of a bayonet connection. Likewise, in another alternative, the engagement means can be configured as half of a plug connection. It goes without saying that the respective other half of the engagement means is arranged on a respective counterpart, in this case on a connecting element on the dispensing device.

[0045] All of these alternatives allow a secure connection, wherein, for example, a threaded connection is suitable for omitting further elements. A sliding connection allows a simple connection of the corresponding elements, as has already been described with reference to the system. The advantages of the bayonet connection and the plug connection have likewise already been described with reference to the system and can be fully applied to the container.

[0046] The projections and / or constrictions for producing the snap connection may be formed on the engagement means. The snap connection provides some protection against accidental opening and may also provide a tactile feedback to the user by which the user can recognize the secure connection of the two elements (in this case the dispensing device and the container).

[0047] The base body is preferably non-detachably connected to the container and is in particular configured as an integral part of the container. This makes manufacturing easier and prevents incorrect manipulation by the user.

[0048] Another aspect relates to a receiving device for receiving a container, in particular a container as described herein. The receiving device comprises a dispensing device. The combination of the receiving device and the dispensing device enlarges the container or holding device into which the refill container can be easily introduced. Thus, by means of the receiving device, an element can be provided which has sufficient strength for repeated use and which is not soiled by the dispensed product. In this case, this is usually provided in a container as described herein, i.e. a refill container.

[0049] The receiving device can be formed from two parts, thereby simplifying the insertion or reception of the container. These parts can form a receiving part and a closing part, wherein the dispensing device is arranged on the closing part.

[0050] The closing part and the receiving part can be connected to each other by a bayonet connection or a threaded connection. These two connections enable the receiving part to be securely connected to the closing part.

[0051] The receiving device may comprise in its interior an extension between the bottom of the receiving device and the connecting element of the dispensing device, which extension is shorter than an associated extension of the container, so that the container can be clamped in the receiving device, in particular between the bottom of the receiving device and the connecting element of the dispensing device.

[0052] This type of embodiment is particularly advantageous if the engagement device is designed as a plug connection. The container can be inserted into the receiving device and by connecting the receiving devices together, the plug connection can be brought into operative connection and the fluid-tight connection can be maintained by the clamping action.

[0066] Figure 1 A perspective view of a system 100 with a receiving device 50 is shown. The receiving device 50 is made of two parts and has a receiving portion 51 and a closing portion 52. The container 20 (see Figure 2 ) is arranged in the receiving device 50. The closing portion 52, i.e. a component of the receiving device 50, is in this case configured as a component of the dispensing device 30. In other words, the dispensing device 30 is arranged on the receiving device 50 and is non-detachably connected to the receiving device 50. In this case, the dispensing device 30 is configured as a pump dispenser.

[0067] Figure 2 Shown according to Figure 1 51, so that the container 20 located in the receiving device 50 is visible. The container 20 is configured as one of dimensionally stable containers. A riser 23 is arranged inside the container 20. The container 20 has a base body 21 at its upper end for effective connection to a corresponding connecting element 31 of the dispensing device 30. For this purpose, an engagement means 22 is provided on the base body 21, which engages with a complementary engagement means 32 on the connecting element 31. Figure 2 The illustrated engagement means 22 , 32 are configured as a sliding connection.

[0068] The standpipe 23 is disposed in the container 20 on the base 21 and is in fluid communication with a corresponding opening on the base 21 (see also Figure 6 The connecting element 31 also has a corresponding opening so that, in the ready-to-use state, the product can be dispensed from the interior of the container 20 by means of the dispensing device 30 .

[0069] By engaging the engagement means 22, 32, a fluid-tight connection is produced between the base body 21 and the connecting element 31. In this case, the engagement means 22 and 32 are configured such that two sealing surfaces, which are arranged on the base body 21 and the connecting element 32, respectively, are pressed against each other.

[0070] Figure 3A and Figure 3B A dimensionally stable container 20 is shown in a side view and in a sectional view. The container 20 has a base body 21 at its upper end. An engagement device 22 is arranged on the base body 21. In this case, the engagement device 22 is configured as a circumferential groove, into which a corresponding counterpart can be inserted laterally. A standpipe 23 arranged on the base body 21 is fastened into the container 20. The standpipe 23 extends to the bottom of the container 20 (not described in more detail), so that the product to be dispensed can be dispensed from the container 20 by a universal connection with a dispensing device. The standpipe 23 can, for example, be fastened to a separate closure element which snaps into the opening of the container 20.

[0071] Figure 4A and Figure 4B A container 20 configured as a flexible bag is shown. At its upper end, the container 20 also has a base 21 for engaging with a corresponding connecting element. The engaging means not specified here are similar to Figure 3A and Figure 3B Since the container 20 shown here is configured as a flexible bag, the standpipe in the container 20 can be omitted. In this type of use, the bag is connected to the dispensing device in a fluid-tight manner and there is no air exchange in the bag. When the product is dispensed, the bag shrinks and can therefore be emptied substantially completely.

[0072] Figure 5 Another embodiment of the system 100 is shown, wherein: Figure 5 The system 100 shown is arranged according to Figure 3A and Figure 3B The system 100 comprises a dispensing device 30 having a connecting element 31. The container 20 has a base body 21. The connecting element 31 is effectively connected to the base body 21. To this end, the base body 21 and the connecting element 31 have complementary engagement means 22 (see Figure 6 ) and 32. As already shown, the engagement means 22 on the container 20 is configured as a circumferential groove. Correspondingly, the engagement means 32 on the dispensing device 30 is configured as a protrusion for engaging in a corresponding groove. The base body 21 and the connecting element 31, in particular the engagement means 22 and 32, are configured as a sliding connection for lateral insertion.

[0073] Figure 6 An enlarged illustration of the sectional view of Figure 3 is shown. A section through the base body 21 and the engaging means 22 located therein can be seen. The base body 21 closes the container 20. An opening 26 for removing the product from the container 20 is arranged in the base body 21. Opposite this opening 26 and extending into the interior of the container 20 is a standpipe 23. The base body 21 also has a ventilation opening 25 so that when removing the product from the container 20, a negative pressure inside the container 20 can be avoided.

[0074] 7A to 7D A system 100 with different embodiments of a receiving device 50 is shown. Fig. 7A The receiving device 50 already described in connection with the previous figures is shown. The receiving device 50 consists of two parts and has a receiving part 51 and a closing part 52. The closing part 52 is non-detachably connected to the dispensing device 30. The separation point between the receiving part 51 and the closing part 52 is located in the upper region of the receiving device 50.

[0075] Figure 7BA receiving device 50 is shown, which likewise has a receiving part 51 and a closing part 52. Here, too, the closing part 52 is non-detachably connected to the dispensing device 30. The separation point between the receiving part 51 and the closing part 52 is located in the lower region of the receiving device 50.

[0076] Figure 7C 5 shows a receiving device 50 which is also composed of two parts. Fig. 7A and Figure 7B In contrast to the receiving device of the dispensing device 30, there is a separation point along the longitudinal axis. A hinge (not visible here) is arranged on the opposite side so that the receiving device 50 can be unfolded like a book. In this embodiment, the dispensing device 30 is constructed independently of the receiving device 50.

[0077] Fig.7D The receiving device 50 is shown as an integral structure. However, the receiving device 50 is open in the lateral area so that the container 20 can be inserted laterally. In this embodiment, the dispensing device 30 is also constructed independently of the receiving device 50.

[0078] Figure 8 A diagram of the replacement process of the container 20 is shown. In this embodiment, the receiving device 50 is constructed as an integral body and is non-detachably connected to the dispensing device 30. In the general use position, the receiving device 50 is opened downward. The container 20 can be introduced into the opening from below. In a first step, the empty container 20 is removed from the receiving device 50 and is separated from the dispensing device 30 accordingly. To this end, the container 20 is rotated about its longitudinal axis and then pulled out of the receiving device 50 in the direction of the longitudinal axis. The engagement devices 22 and 32 not shown here can be configured as threaded or bayonet connections accordingly. A replacement container 20 is then provided. The latter is usually closed with a sealing foil 24. This will be removed. Subsequently, the replacement container 20 is inserted into the receiving device 50 again from below. The system 100 is now fully ready for use again without wasting residues of the product or the user and / or the reusable container, i.e. the receiving device 50, coming into contact with the product and / or becoming dirty.

[0079] The sealing element can be arranged in the region of the engagement device. This can be in the form of a surface seal. By screwing or fastening the container to the dispensing device, the sealing element can be clamped between the two elements, thereby producing a sealed connection.

[0080] Alternatively, the sealing element can also be provided by a form fit or force fit, for example by engaging two tapered elements (e.g., tapered connectors) into respective tapered openings. A corresponding sealing effect can be produced by axially connecting the container to the dispensing device and holding it by a threaded or bayonet connection.

[0081] In particular in the case of a connection with a bayonet lock, the bayonet lock is designed in such a way that a prestress is exerted on the sealing element or the connecting part.

[0082] Fig. 9 Another illustration of the replacement process of the container 20 is shown. In this embodiment, the receiving device 50 is configured as a reference Figure 1 , Figure 2 and Fig. 7A The receiving device 50 is made up of two parts and has a receiving part 51 and a closing part 52. The dispensing device 30 is non-detachably connected to the closing part 52, so that the closing part 52 forms a component of the dispensing device 30. The closing part 52 and the receiving part 51 are connected to each other by a bayonet connection. Therefore, in a first step, the receiving device 50 is opened by rotating the closing part 52 and lifting it from the receiving part 51. Alternatively, a thread can also be provided.

[0083] from Fig. 9 As can be seen from the middle illustration of , the standpipe 23 that can be inserted into the container 20 is arranged on the dispensing device 30. The empty container 20 is taken out of the receiving part 51 and a new, unopened container 20 is inserted into the receiving part 51. The unopened container 20 is closed with a sealing foil 24, which is then removed. Arranged on the container 20 is a base body 21, which has engagement means that are not described in detail here. In this case, these engagement means are configured as threads. The corresponding mating threads are located on the dispensing device 30. Before the closure part 52 is placed on the receiving part 51, the container 20 is screwed into the dispensing device 30. Subsequently, the dispensing device 30 is inserted into the receiving part 51 together with the container 20, and the receiving part 51 is closed with the closure part 52.

[0084] Fig.10 Another illustration of the replacement process of the container 20 is shown. In this embodiment, the receiving device 50 is configured as a reference Figure 7C As described. The receiving device 50 is constructed in two parts and has two halves, wherein the two halves are connected to each other by a hinge. In order to replace the container 20, the receiving device 50 or the two halves of the receiving device 50 are unfolded, and the container 20 is removed from the receiving device 50 together with the dispensing device 30 fastened thereto. In this embodiment, a standpipe that can be inserted into the replacement container 20 is also arranged on the dispensing device 30. The replacement container 20 is also closed with a sealing foil 24, which is removed before use. The container 20 can be placed in the receiving device 50 and connected to the dispensing device 30. A base with an engagement device is provided on the container 20. Similarly, an engagement device at the connecting element 31 is provided at the dispensing device 30. These can be constructed as described herein.

[0085] Fig.11Another illustration of the replacement process of the container 20 is shown. In this embodiment, the receiving device 50 is configured as a reference Fig.7D As described. In other words, the receiving device 50 has a transverse or lateral opening and is of integral construction. In order to replace a used container 20, the container 20 is pivoted laterally out of the receiving device 50 together with the dispensing device 30 and the container 20 is separated from the dispensing device 30. Correspondingly, a new container 20 is inserted laterally into the receiving device 50. The latter is likewise closed with a sealing foil 24, which is removed before use. It can be seen that the container 20 according to the present embodiment has a base body 21 on which an engagement device 22 in the form of a thread is arranged. In the present embodiment, the dispensing device also has a standpipe for introducing the container 20.

[0086] Fig.12 Another illustration of the replacement process of the container 20 is shown. In this embodiment, the receiving device 50 is configured as a reference Figure 1 , Figure 2 and Fig. 7A As described. However, the system for connecting the container 20 to the dispensing device 30 has a different design. The receiving device 50 is composed of two parts and has a receiving part 51 and a closing part 52. The closing part 52 is non-detachably connected to the dispensing device 30 and constitutes a component of the dispensing device 30. In order to open the receiving device 50, the closing part 52 is rotated relative to the receiving part 51 and lifted from the receiving part 51. The empty container 20 is removed and the full container 20 is introduced into the receiving part 51. In this case, the full container 20 is shown in a cross-sectional view, and the liquid level of the product can be seen in the container 20. The new container 20 is closed with a sealing foil 24. The connector 33 is provided on the dispensing device 30 as an engagement device of the connecting element 31 for engaging the corresponding opening 26 on the base body 21. Therefore, in this case, the engagement device is configured as a plug connection. A fluid-tight connection is provided by pushing the connector 33 into the corresponding opening 26. To this end, the closing part 52 is placed on the receiving part 50 along the axial direction, so that the connector 33 is pushed into the opening 26 on the container 20. For this purpose, the connection piece 33 and the opening 26 are conical. Subsequently, the closing part 52 is rotated and fixed relative to the receiving part 51. In this case, the connection between the receiving part 51 and the closing part 52 is correspondingly configured as a bayonet connection. The system 100 is now completely ready for use again, without waste of product residues or the user and / or the reusable container, i.e. the receiving device 50, coming into contact with the product and / or becoming soiled.

[0087] In order to provide a good sealing effect, the receiving device 50 in the assembled state has in its interior between its bottom and the connecting element 31 a shorter area than the relevant area of ​​the container 20, so that the container 20 is clamped in the receiving device 50. Accordingly, a force is exerted on the connecting piece 33, pressing it into the opening 26.
