Abstract

The device (1) has two storage regions (2, 3) for receiving respective components, where the storage regions are connected with respective discharge passages (7, 8). The discharge passages open into a common mixing channel (9) that includes a mixing element, which is enclosed by covering films (38, 39). The mixing element comprises a protrusion, where one of the films lies on the protrusion. The mixing element is retained between the films. The films are connected with one another in a support region. An independent claim is also included for a method for manufacturing a storing device.

Description

The invention relates to a device for storing and dosing a plurality of components, which are mixed together immediately prior to use and to be supplied in the mixed state of use. Such devices are used for example for storage of the individual components of a multi-component adhesive. Another application is found in the food industry or for the packaging of medical preparations. Common to all these devices is that the individual components are stored until they are consumed in separate storage areas that can be closed.

If such devices are designed for single use, they are also referred to as blister packs. A chamber of a blister pack for a liquid or powdered filling material usually consists of a deep-forming film and a sealing film, which closes the filling material sealingly in the storage state from the environment.

In various applications for food, cosmetics, pharmaceuticals, dental products, sealants or adhesives, several components are stored separately prior to their intended use. However, the components are used together, usually in a mixed state. For this purpose, devices are used, as for example in the EP1947028 A2 are shown.

The device according to EP1947028 A2 comprises a first storage area for receiving a first component and a second storage area for receiving a second component, wherein the two storage areas are arranged substantially one above the other. Each storage area includes a bulge, which is tightly closed with a cover. The cover is sealable with the bulge to form a seam and the storage areas are outside the seam connectable by a connecting element, which is in particular a welded connection. The covers are made of the same material, which is designed as a film, which is designed in particular as a deep-forming film. In order to improve the chemical or physical properties, such as chemical resistance, it is also possible to use multilayer films, for example aluminum composite films, in which the surface to be welded consists of a good weldable plastic.

To the two storage areas can connect a mixing element, as for example for one of the DE 20 2005 001 203 U1 known multi-component foil container is shown. The storage areas open unilaterally into a mixing area which is separated from the storage areas in such a way that each component is stored separately in the storage area provided for it, as long as it is stored.

In the first, in the DE 20 2005 001 203 U1 illustrated embodiment dividers are arranged between the storage areas. Each storage area is designed as a half-shell filled with a component, to which a groove-shaped depression adjoins, into which a mixing element can be inserted. The dividers are forced apart by the exiting components at a predetermined location to open a passage to the trough-shaped depression forming the discharge channel. For this purpose, a compressive force must be exerted on the mixing element. A user grasps for this purpose the housing which contains the mixing element and presses it in the direction of the storage areas.

According to other embodiments of the DE 20 2005 001 203 U1 At the mixer an opening mandrel is attached to a connection between the Produce storage areas and the mixing element by cutting through a partition, which allows the discharge of the components.

For this purpose, the mixing element is displaced by means of a plunger relative to the housing. Also according to this embodiment, the user of the device must hold the housing of the mixing element with one hand and attach the plunger at the outlet end of the mixing element to exert a compressive force on the mixing element in the direction of the storage areas.

This solution entails that the housing of the mixing element is dimensionally stable and withstands the pressure forces required to hold the housing.

The force to be pressed apart to separate the separating webs or to sever the dividing wall on the plunger is relatively large, since the dividing webs or dividing wall must have a sufficiently large wall thickness in order to protect the filling compound from impacts and damage during transport and storage and to prevent their escape. The ram is accordingly small for a single use device, so it requires some skill and power to safely open the passage to the storage areas when the components of the filling are to be mixed and discharged.

It is therefore an object of the invention to provide an easy-to-use, inexpensive device that can be safely opened by means of a simple handle using low opening forces. Furthermore, it is an object of the invention to simplify the manufacture of the device and to reduce the number of manufacturing steps.

This object is achieved by the device for storing a plurality of components, which are intended for common consumption. The device comprises a first storage area for receiving a first component and a second storage area for receiving a second Component. The first storage area is arranged opposite to the second storage area. That is, the first storage area is located above or below the second storage area.

This opposite arrangement is particularly advantageous because the fillers from both supply areas can be applied simultaneously. For this purpose, pressure can be exerted manually on the two storage areas by being compressed with one hand. Alternatively, the device can be clamped in a Austraghilfsmittel by means of which a pressure on the storage areas can be applied. Under this pressure, the flexible shell of the storage areas yields. The volume of the storage area decreases continuously with progressing discharge until the filling material has completely left the storage areas.

The first storage area is separated from the second storage area by a release film such that the first storage area extends on a first side of the release film and the second storage area extends on a second side of the release film. The first storage area can be connected to a first outlet channel. The second storage area can be connected to a second outlet channel. The first outlet channel and the second outlet channel open into a common mixing channel. The mixing channel contains a mixing element which is surrounded by a wrapping film. The wrapping film thus forms the wall of the mixing element. Thus, the provision of a tube for receiving the mixing element can be omitted. This eliminates the manufacturing step of connecting pipe and mixing element. The mixing element may in particular be designed as a static mixing element. The mixing element comprises a protuberance on which at least one of the first and second film rests.

The opening of the storage areas for the discharge of the two components is effected by a simple buckling movement. Due to the bending movement, a separating element arranged on the mixing element cuts through the separating film, which closes at least one of the storage areas. By the kink movement be applied by the user only small forces on the storage areas and on the mixing element. It follows that the danger is no longer that the mixing element would be mistakenly deformed by the user. The user is encouraged to attack the mixing element as close as possible to its exit end, whereby it can exploit the effect of the lever and can sever the release film by utilizing the lever principle.

According to a preferred embodiment, the cover film comprises a first film and a second film, so that the mixing element is held between the first and second film. This variant is advantageous because the first film serves to receive the first storage area and to receive the first outlet channel and one half of the mixing channel. The second film serves to accommodate the second storage area and for receiving the second outlet channel and the other half of the mixing channel. The first and second foils thereby form the walls of the corresponding storage areas as well as a part of the walls of the corresponding exit ducts. Likewise, the wall of the mixing element is formed by the first and second foils.

The first film is located on an outer side of the mixing element on the second film along a support area, wherein the first film is connected to the second film in the support area. Under the outside of the jacket of the mixing element should be understood. According to conventional solutions, the jacket is formed by a tube. The support area is advantageously flat, which allows the positioning of a tool for welding or sealing the two films along the support area in a simple manner.

The first exit channel is received in the first foil and the second exit channel is received in the second foil. The first storage area is accommodated in the first film and the second storage area is accommodated in the second film. With this solution, the appropriate Reservoir areas, outlet channels and the associated half of the mixing channel are each formed by a film.

Alternatively, the first film and the second film may each be formed as a part of a wrapping film. Such a wrapping film can be loaded with a tool which has the recesses corresponding to the storage areas, the outlet channels and the mixing channel. The wrapping film is inserted into the recesses or injected in liquid form into the recesses in such a way that it forms a thin layer which rests against the walls of the corresponding recesses. The recesses of the storage areas are filled with the appropriate components, optionally closed by a release film and inserted the mixing element in the mixing channel. The mixing element preferably also contains the outlet channels, so that after inserting the mixing element, the two parts of the enveloping film can be folded and connected to each other in the support areas. The components as well as the mixing element with the outlet channels are already integrated in the cladding film, so that hereby the manufacture of the device is already completed.

At the two side edges of the mixing element, the first foil and the second foil lie on one another and form a support region. Here, the first film and the second film touch and can be connected to one another at this point, so that the mixing channel is received in a fluid-tight manner in the first film and the second film or the enveloping film. The connection can advantageously be made by welding.

In this case, a cavity remains between the mixing element and the first film and the second film or the cover film. If the mixing channel has a circular cross-section and the mixing element also has a circular cross-section, this cavity is small, but it can still happen that leaks occur when discharging the first and second components. The foils or wrapping foil can of peel off the wall of the mixing element when the components exert a pressure on the inner surface of the films or wrapping film.

To increase the mechanical stability of the mixing channel, the mixing channel contains at least one protuberance, so that the corresponding film rests on the protuberance. This results in the unexpected advantage that the corresponding film or wrapping foil tightly abut the mixing channel and even under the pressure of the components to be discharged, a detachment of the films or enveloping films can be avoided by the mixing channel.

Advantageously, the protuberance extends on the outside of the mixing element. The protuberance extends substantially over the entire length of the mixing element, so that each of the films rests along at least a large part of the length of the mixer element on the protuberance.

If the mixing element is inserted in a single cover film, a single protuberance can be provided. If the mixing element is inserted into a first film and covered by a second film, advantageously two protuberances are provided. These protuberances are in this case preferably arranged on opposite sides of the mixing element.

The protuberance may be formed as a wedge-shaped body having first and second side surfaces so that the first film rests on the first side surface and the second film rests on the second side surface, and an end surface.

A method for manufacturing a device for storing a plurality of components intended for common consumption comprises the following steps
Providing a first film and inserting the first film into a recess of a mold
Inserting a mixing element in the recess Providing a second film and covering the mixing element with the second film, connecting the first film to the second film so that the mixing element is received in the first film and the second film, wherein the mixing element comprises a protuberance on which at least one of the first and second films rest.

In particular, in the form of a recess for a mixing channel and / or a first outlet channel and a first and / or second storage area is provided.

The second film is inserted into a recess, wherein the recess forms the second storage area, wherein after inserting the second film in the recess of the second storage area is filled with a second component, wherein the second storage area after completion of the filling with the second component a release film is covered and the release film is so connected to the second storage area that the second component is trapped in the storage area.

After inserting the mixing element into the recess, the first storage area is filled with a first component. After filling the first storage area with the first component, the film with the filled and sealed second storage area is held in a mold and the mold is positioned on the first film such that the recess for the mixing channel encloses the mixing element and then the first and the second film are joined together so that the second component is enclosed in the second storage area and the mixing element is enclosed by the first film and the second film.

After filling the first storage area, an additional separating film can be placed on the first storage area and the first component can be enclosed between the separating film and the first storage area by connecting the separating film to the first storage area in a fluid-tight manner. At least one of the first and second exit channels may have a bottom. This floor is according to a preferred embodiment in one piece with the outlet channels and may even form a unit with the adjoining the outlet channels mixing element. The bottom has an end facing the corresponding storage areas, a kink being formed from the bottom end. The kink point is the axis of rotation for a bending movement of the mixing element relative to the storage areas. By means of this bending movement, an opening can be made in the corresponding storage area in order to discharge the corresponding component from the storage area.

Advantageously, at least one of the outlet channels on a separating element which extends beyond the kink in the direction of the corresponding outlet channel associated with the storage area. By means of the separating element, the separating film, which seals the first component in the first storage area and holds the second component in the second storage area in a sealed manner, can be severed.

The separating element advantageously contains a recess. This recess ensures that the severed film does not block the corresponding exit channel.

Advantageously, the separating element has a first and a second arm which extends beyond the kink point in the direction of the storage area associated with the discharge channel. Alternatively, the storage area can also have an arm which extends beyond the kink point in the direction of the corresponding outlet channel. This arm is in the event that it emanates from the outlet channel so connected to the outlet channel, that it participates in a movement of the outlet channel whose movement. This means that movement of the outlet channel causes movement of the arm. If the outlet channel is moved by the bending point relative to the storage areas by means of a rotary movement, the corresponding arm of the separating element comes into contact with the film and begins to exert a compressive force on the film. By this pressure force, the film can be weakened or scratched, so that the way for the corresponding component is released in the direction of the outlet channel.

The arm according to one of the preceding embodiments may for this purpose in particular have a cutting edge facing the cutting edge. The cutting edge is in particular configured such that after contacting the cutting edge with the release film by applying a low compressive force, a slot-shaped opening in the release film can be introduced. The cutting edge is in particular arranged at or in the vicinity of the tip of the separating element, ie at the point where the two arms come together.

At least one of each of the first and second arms, which are arranged adjacent to one another, form a tip, on which a cutting edge facing the separating film is arranged. If the cutting edge extends over at least part of the side of the arm facing the release film and if this cutting edge in the tip runs together punctiformly, a particularly low compressive force is required in order to cut through the release film since the entire compressive force can be concentrated to one point and Thus, a small deflection of the channel is required to effect a puncture of the release film.

According to a particularly preferred embodiment, the recess is surrounded by the tip, the corresponding first and second arm, as well as the bottom of the corresponding outlet channel. This results in the largest possible opening, so that it can be safely avoided that a part of the severed release film closes this opening again and the discharge of one of the components is delayed at the expense of the other component and therefore the mixing ratio of the two components would be changed in an inadmissible manner ,

The exit channel includes a bottom, and a first wall and a second wall extending from the bottom. The wall at the exit channel prevents one of the first or second foils closing the exit channel from resting on the floor.

At least one of the arms can connect to the corresponding first or second wall. In particular, the arm may be formed by at least one of the first and second walls. Arm and walls can be part of a one-piece mixing element. Such a mixing element can be produced in particular as a plastic component by injection molding.

The tip-opposite surface may be rounded. Such a rounding is particularly advantageous when the separating element is surrounded by the first or second film, which must not be injured during storage of the device. Since the storage areas are surrounded by the same first or second film forming a wrapping film, it is possible to wrap the discharge channels and the mixing element with this wrapping film in one operation. However, this wrapping film must be able to deform under finger pressure. If this wrapping film reaches an edge, it is severed, as is desirable when the separating element is in contact with the separating film between the storage areas, but in no case is it desirable in the case of the wrapping film, since the corresponding component can escape through the resulting leak.

With an inventive device for storing a plurality of components which are intended for common consumption, as in the Fig. 1 . 2 and 3 According to a first embodiment is shown in three views, two components can be stored separately and jointly discharged as needed. Fig. 1 shows a view of the device 1 from above, wherein the first storage area 2 associated part of the device 1, which is intended to receive the first component is shown.

The device comprises a first storage area 2 for receiving a first component 5 and a second storage area 3 for receiving a second component 6 Fig. 1 an eruption is shown in the wall of the storage area 2 to reveal the view of the hidden component 5 underneath. Each of the storage areas 2, 3 may be formed in particular as a half-shell. The first storage area 2 is separated from the second storage area 3 by a film 4, so that a closed chamber is formed between each of the two storage areas and the film. Each of the two storage areas 2, 3 has a support element 31, 32. The support element 31, 32 adjoins the closed chamber. Along the support element, the first storage area 2 and the second storage area 3 can be sealed to form a seam 33 and, if appropriate, can additionally be connected or welded outside the seam 33 by a connecting element 34. The support element 31 and the storage area 2 may consist of a first film 38 exist. The support element 32 and the storage area 3 may consist of a second film 39. The first and second foils 38, 39 may be formed as part of a wrapping film.

For particularly reactive components, it may be necessary to provide a special lining or coating on the inner wall of the corresponding storage area 2, 3. In particular, the corresponding wrapping film can be constructed of several layers that fulfill different functions.

Fig. 2 shows a view of the device, for which the walls of the storage areas 2,3, the mixing channel 9 and a part of the first and second outlet channels 7, 8 have been removed. In this view, the film 4 is partially omitted, so that the course of the second outlet channel 9 is visible until it enters the mixing channel 9, which is provided downstream of the outlet channels 7,8. The mixing channel 9 includes a mixing element 35. Between the first and second storage area 2,3 and the first and second outlet channel 7, 8 a kink 10 is arranged.

The first storage area 2 and the first exit channel 7 are arranged on the first side 11 of the film 4, the second storage area 3 and the second exit channel 8 are arranged on the second side 12 of the film 4. The first side 11 is disposed opposite to the second side 12.

At least one of the outlet channels 7, 8 has an arm 13, 14, 15, 16, which extends beyond the kink point 10 in the direction of the corresponding outlet channel 7, 8 associated storage area 2, 3. Each two adjacent arms, which are associated with an outlet channel, are connected together, according to Fig. 2 the arm 13 is connected to the arm 14, the two arms 13 and 14 belonging to the outlet channel 7. Furthermore, the arm 15 is connected to the arm 16, the two arms 15 and 16 belonging to the outlet channel 8. Each two arms form a separating element 24, 44.

Fig. 3 shows the view of the second storage area 3, wherein the first storage area 2 as in Fig. 2 is omitted. Fig. 3 thus shows the part of the device 1, which is located on the side 12 and additionally the first outlet channel 7. The film 4 is in Fig. 3 omitted, so that the second storage area 3 is better visible.

For the embodiment according to Fig. 1 and 3 is at the end of the storage area, which is opposite to the mixing channel 9, a web 37 is arranged. This web 37 can be held in a Austraghilfsmittel of a first holding element. The Austraghilfsmittel is not shown here. An example of such a discharge aid can be found in the W02006 / 079413 ,

Fig. 4a shows a further embodiment of the inventive device. Like-acting parts bear the same reference numerals as in FIG Fig. 1 to 3 and will not be described in detail unless their function differs from the first embodiment. For example, the web 37 is missing in this embodiment, so that this variant is particularly suitable for the manual discharge of the filling compound, which is located within the first or second storage areas.

In Fig. 4b It is shown that the mixing channel 9 and the two storage areas 2, 3 are surrounded by a first and a second film 38, 39, which serves for receiving the components and for receiving the mixing element 35. Of course, the following description also applies to the first embodiment.

The preparation of a device according to one of the preceding embodiments is based on the following Fig. 5 to 12 will be explained in detail.

Fig. 5 shows a first method step for producing a device according to Fig. 1 to Fig. 4b wherein the second film 39 in the recess is inserted, which forms the second storage area 3. In addition, a recess for the second outlet channel 8 and the mixing channel 9 is shown. The second film is preferably made of flexible material so that it fits on an in Fig. 5 not shown form or pad rests. This form contains the corresponding recesses.

In Fig. 6 It is shown that, following the insertion of the second film 39 into the recess, the second storage area 3 is filled with a second component 6. For this purpose, a container 53 containing the second component is positioned above the storage area 3 and this storage area is filled with the second component 6.

Fig. 7 shows that the second storage area 3 is covered after completion of the filling with the second component 6 with a release film 4 and the release film 4 is so connected to the second storage area 3, the second component 6 is included in the storage area 3. The connection can be made by one of the methods which has also been mentioned in connection with the connection of the first and second foils 38, 39.

Subsequently or in one of the process steps according to Fig. 5 to 7 parallel running step is according to Fig. 8 a first film 38 on a pad, which may be part of a form, laid, which has a recess in the shape of the first storage area 2 and a recess for the first outlet channel 7 and for the mixing channel 9. The first film 38 is placed on the substrate in such a way that it rests in all recesses on the substrate. The recess for the storage area 2 is not connected to the recess for the first outlet channel 7 or the mixing channel 9, which incidentally also for Fig. 5 to 7 applies.

Therefore, according to Fig. 9 the recess of the storage area 2 are filled with the first component 5. For this purpose, again a container 52 is used which contains the first component 5 and by means of which Component in the desired amount at the desired location, the first storage area 2 can be dosed.

If the storage area 2 is filled with the first component 5, the first storage area 2 can also be covered with a separating film 40 and closed in a fluid-tight manner. This step is optional because it can not come into contact with the first component. For low-viscosity components, which can get into the outlet channel, the provision of a second release film 40 (see Fig. 2 ) advantageous. The component 5 is enclosed in the storage area 2 in this case. This variant is also advantageous when it comes to delays in the assembly of the device and / or the second component may not be exposed to air or is sensitive to light.

In Fig. 10 on the other hand, no separate release film 40 is provided for the subsequent step of inserting the mixing element 35 into the mixing channel 9 for the first storage area 2. The mixing element 35 includes a portion of the first and second exit passages formed as open channels. The mixing element 35 is shown in detail in FIG Fig. 13 therefore, it is intended to refer to the description at this point Fig. 13 to get expelled.

Fig. 11 shows the connection of the two halves of the mixing channel with each other and the positioning of the two storage areas 2, 3 and the associated outlet channels 7.8. In Fig. 11 In addition, a part of a mold 25 is also shown. Here, the storage area 3 was cut open, so that the resting of the film 39 is clearly visible in the corresponding recesses. Furthermore, the release film 4 is shown in section, which closes the storage area 3, which contains the second component 6.

The first film 38 and the second film 39 are joined together along the surfaces which have no recess, so that on the one hand the second component 3 is enclosed in its storage area 3, as well as the mixing element 35 together with the first and second exit channels 7, 8 included in the first and second slides, as in Fig. 4a or Fig. 4b is shown.

Fig. 12 differs from Fig. 11 only in that the form is omitted. The film 39 is shown here from the outside, on which the recesses for the second storage area 3, the second discharge channel and the mixing channel appear as bulges.

In Fig. 13 is the mixing element 35 and the corresponding outlet channels 7, 8 shown in detail. The mixing element 35 and the outlet channels 7, 8 are designed as a single component, which is advantageously produced by injection molding. Each of the outlet channels consists of a bottom 18, 19 and each of a first side wall 20, 22 and a second side wall 21, 23rd

The bottom 18, as well as the bottom 19, of which only one edge is visible, can pass into a plate-shaped element 41. At least one of the first and second outlet channels 7, 8 has a bottom 18, 19. The bottom has an end 29 facing the corresponding storage areas 2, 3, the kink 10 being formed by the end 29 of the floor.

Each of the arms 13, 14, 15, 16 may for this purpose have a cutting edge 17 facing the film 4.

The outlet channel 7,8 comprises a bottom 18, 19, on which the film 4 extends, and a first wall 20 and a second wall 21, wherein the arm 13, 14, 15, 16 from the bottom 18, 19 through the film 4th is disconnected.

Each of the arms 13, 14, 15, 16 is formed by at least one continuation of the first or second walls 20, 21, 22, 23. The separating element 24, 44 each comprises a first and second arm 13, 14, 15, 16, which extends from the kink 10 in the direction of the corresponding storage area 2, 3. Alternatively, the respective bottom 18, 19 of the corresponding outlet channel 8, 9 can open into a separating element 24, 44, which is not shown in the drawing.
