Description

The invention relates to a multi-component film container according to the preamble of claim 1.

A multi-component film container having the features of the preamble of claim 1 is known from WO 2000/009 415 out.

Another multi-component film container is from the US 4,952,068 known. There, the multi-component film container is formed by two relatively thin and compliant plastic films defining a first and a second chamber for receiving the two different components of a two-component adhesive. Both chambers have outlet openings in a mixing area, wherein the components are retained in the chambers unmixed by separating films before use. To express the components of the container is compressed in the region of the chambers, so that the release films break open and get the two components in the mixing area. In the mixing area integrally formed deflecting elements are arranged on the container foils, by means of which the two components are mixed together. The mixing area is followed by a discharge area with an outlet opening for the component application. Due to the integrally formed on the container foils deflection elements, however, the possible embodiments of the mixing structures are limited, so that a relatively large mixing volume is required to achieve an effective mixing. Due to the limited embodiments of such a mixer very long flow paths of the components to be mixed are also required to achieve a sufficient mix, resulting in a high Auspresswiderstand. In addition, the deflection elements are tuned to certain components and applications and can not be easily changed.

Object of the present invention is to provide a multi-component film container and a container assembly of the type mentioned, which are easy to prepare and allow a particularly effective mixing of different components. This object is achieved by a multi-component film container with the features of claim 1. Advantageous embodiments and expedient developments of the invention are specified in the subclaims.

In the case of the multicomponent film container according to the invention, it is possible by means of the separate mixing element to realize significantly more complex deflecting elements and mixer structures, thereby enabling particularly efficient mixing. By the chambers facing the extended end of the mixing element and arranged thereon at least one opening mandrel for opening the at least one seal a simple opening of the sealing of the chambers of the multi-component film container is made possible. Compared to conventional multi-component containers of this type, the components need not be premixed by multiple back and forth to achieve a good mixing. The separate mixing element allows a particularly effective design and arrangement of the deflection, whereby the mixer volume is reduced. The short flow paths in the mixer and the compact mixer structure make it easy to express the components. The handling of the multi-component film container is extremely simple and requires no elaborate preparations. The container must be pressed together in the area of the two chambers only by hand, whereby the two components are pushed through the mixing element and mixed there without much effort. Due to the separate mixing element, the multi-component film container can also be adapted relatively easily to different needs and components. Depending on the nature and properties of the components, a suitable mixer can be selected either already during production or even before use without major changes in production technology.

In a particularly advantageous embodiment, the chambers are formed in two half-shells, which are made of a flexible, yet dimensionally stable material. The two half shells can be easily filled and then assembled. The dimensionally stable material can prevent the chambers from bulging during the squeezing process, so that the entire pressure applied for squeezing the components out of the chambers into the discharge channel is available.

In a manufacturing technology simple embodiment of the discharge channel is formed by two groove-shaped bulges in the two half-shells. However, the chambers for storing the components can also be arranged in a separate storage part and the discharge channel in an attachable to the storage part dispensing tube. As a result, discharge pipes with different mixing elements can be provided for different components.

The seal for preventing mixing of the components prior to use may be formed by a release film or release films disposed between the two chambers. The seal can also be formed by partitions or partitions between the chambers and the discharge channel.

For expressing and mixing the components, the seal may be destroyed or opened by separate opening elements, e.g. can be designed as opening mandrels, which are arranged on the mixing element.

The in the FIGS. 1 to 14 shown examples of multi-component film containers are not part of the invention, but serve to facilitate the understanding of the invention according to the in Fig. 15 to 31 to facilitate embodiments shown.

The in FIG. 1 shown multi-component foil container has an in FIG. 2 separately shown lower half shell 1 and an identically shaped upper half shell 2, which made of a dimensionally stable plastic film by deep drawing or thermoforming and are firmly joined together by welding or gluing. The multi-component film container is functionally subdivided into a storage area 3 for receiving and sealed storage of two components, for example a two-component adhesive, and a common mixing area 4, in which the two components are mixed before discharge. In the storage area 3 of the multi-component film container two chambers 5 and 5 'are provided, which are formed by bulges in the respective half-shells 1 and 2 and separated by a release film 12. The mixing region 4 contains an open at the front end discharge channel 6, which is formed by trough-shaped bulges 7 and 7 'in the two half-shells 1 and 2. The two channel-shaped bulges 7 and 7 'are separated by separating webs 8 and 8' from the chambers 5 and 5 'and shaped such that the limited by them discharge channel 6 has a square or rectangular cross-section over almost the entire length. Only at the front end are the bulges 7 and 7 'shaped to form a short applicator nozzle with a circular discharge opening. In the discharge channel 6 is an in FIG. 2 illustrated mixing element 9 is arranged.

In FIG. 2 only the lower of the two identically designed half-shells is shown. How out FIG. 2 shows, the chamber 5 is separated by the separating web 8 of the channel-shaped recess 7. In the groove-shaped recess 7, the mixing element 9 made of a dimensionally stable plastic, for example by injection molding is used. The mixing element 9 shown here has a main body 10 with angled webs 11 and openings formed thereon. The webs 11 are angled in different directions, so that there is a particularly effective deflection and mixing of the components. The mixing element 9 may also have a different structure depending on the purpose or use. For example, the mixing element can also be round or conical and have a spiral-shaped mixing structure.

Between the two half-shells 1 and 2 is the in FIG. 1 only schematically indicated release film 12 is arranged, which is applied after filling the two chambers 5 and 5 'on one or both of the previously filled half-shells 1 and 2, before they are then placed on each other and firmly connected. The release film 12 forms a seal which ensures that the two in the Do not mix chambers 5 and 5 'together before use.

To discharge the two components from the multi-component film container, the two half-shells 1 and 2 can be compressed in the region of the chambers 5 and 5 'by hand. The release film 12 is designed such that it is lifted by the pressure generated in the compression of the half-shells 1 and 2 within the chambers 5 and 5 'in the region of the separating webs 8 and 8' of the half-shells 1 and 2 and an exit of the components of the Chambers 5 and 5 'allow. Also, the dividers 8 and 8 'are designed so that they are pressed apart by the exiting components at a predetermined location and form a passage from the chambers 5 and 5' to the discharge channel 6. As a result, the components can pass into the discharge channel 6 and through the mixing element 9 to the discharge opening. The two components are mixed together and the adhesive or the like. Can be applied directly to a desired location.

That in the FIGS. 3 and 4 schematically shown second example of a multi-component film container differs from the first example only by the configuration of the mixing element 9. Corresponding parts are therefore also provided with the same reference numerals. In the embodiment shown here, the mixing element 9 is slidably disposed within the discharge channel 6 in the longitudinal direction and has at its the chambers 5 and 5 'facing inner end an integrally formed opening mandrel 13 with two tips. At the other end of the mixing element 9, a plunger 14 protruding outwardly from the discharge channel 6 is formed.

To connect the chambers 5 and 5 'with the discharge channel 6, the mixing element 9 by means of the plunger 14 by hand in the direction of the chambers 5 and 5' is pressed, so that the tips of the opening mandrel 13 between the dividers 8, 8 'of the two half-shells 1 and 2 are pushed and thereby the dividing webs 8 and 8 'spread apart to form a passage. In addition, the separating film or separating films 12 are lifted off from the half-shells 1 and 2 by the tips of the opening mandrel 13, so that the components from the chambers 5 and 5 'can be pressed into the discharge channel 6 and through the mixing element 9 to the discharge opening. So that the mixed components can also escape through the discharge opening, the plunger 14 can after the insertion of the mixing element 9 and retraction are rotated to its original position about its longitudinal axis and thereby detached from the mixing element 9.

That in the FIGS. 5 and 6 illustrated third example differs from the aforementioned embodiments essentially in that the trough-shaped bulges 7 and 7 'at the chamber end end elongated inclined parts 15 and 15', in addition to a forwardly extended portion 16 and 16 'of the chambers 5 and 5 'are arranged. How out FIG. 6 As can be seen, the inclined portion 15 of the bulge 7 and the chamber 5 are arranged with their extended portion 16 side by side, that when juxtaposing the identical half shells 1 and 2, the oblique parts 15 and 15 'of a half-shell respectively with the extended portions 16 and 16 'get the other half shell to cover. On the two inclined parts 15 and 15 'are externally pressed and inwardly projecting opening mandrels 17 and 17' are arranged, through which the arranged between the half shells 1 and 2 separating film or release films 12 can be pierced without damaging the outer skin of the container by hand or . can.

In the in the FIGS. 7 and 8 shown fourth example, a separate discharge pipe 18 is provided with the discharge channel 6 arranged therein. The discharge pipe 18 can be placed on a separate storage part 19 of the local Mehrkomponentenfo lienbehälters. The storage part 19 also consists of two identical half-shells 1 and 2, in which the chambers 5 and 5 'formed by bulges are located. The two chambers 5 and 5 'are filled here with different components. The sealing takes place here by a separating film 12 arranged between the half shells 1 and 2 and by a respective front partition wall 21 of the half shells 1 and 2. The front partitions 21 of the two half shells 1 and 2 form the chambers 5 and 5 'of the discharge channel 6 the discharge pipe 18 before use separated. The discharge pipe 18 is connected via a sleeve-shaped Aufsteckteil 20 sealed to the supply part 19 to the outside. To connect the chambers 5 and 5 'with the discharge channel 6, the partitions 21 of the half-shells 1 and 2 must be pierced. For this purpose, an opening mandrel 22 provided with two tips is integrally formed on the chamber-side end of the mixing element 9 arranged in the discharge pipe 18. Through the two tips of the opening mandrel 22, the front partitions 21 of the storage part 19 when placing the applicator tube 18th pierced so that the components can get into the discharge channel 6 of the discharge tube 18.

In the in the FIGS. 9 and 10 shown fifth example, a discharge pipe 23 is slidably mounted on a storage part 24 in the longitudinal direction. The storage part 24 again consists of two identical half-shells 1 and 2, in which the bulges formed by bulges 5 and 5 'are formed. Again, the two chambers 5 and 5 'separated by a between the half shells 1 and 2 arranged release film or release films 12. Within the half-shells 1 and 2 partitions 25 and 25 'are provided which prevent leakage of the components in the discharge channel 6 before use. In this embodiment, the discharge pipe 23 is designed such that the mixing element 9 can be inserted into the discharge channel 6 from the discharge opening.

As in Fig. 10 shown, the discharge pipe 23 is slidably mounted via a hollow cylindrical attachment piece 26 on a circular cross-section neck 27 of the storage part 24 in the longitudinal direction. By an inwardly projecting annular ridge 28 on the attachment piece 26 and a corresponding shoulder 29 on the neck 27, the axial displacement of the discharge tube 23 is limited to the front. The discharge pipe 23 has an opening mandrel 30 arranged within the attachment piece 26 with two separate tips 31 and 31 'for piercing the two partitions 25 and 25'. Passage channels 32 and 32 'are provided in the two tips 31 and 31' for the two components. In FIG. 10 are also the openings 33 in the mixing element 9 can be seen.

By pushing the discharge pipe 23 in the direction of the chambers 5 and 5 'pierce the tips 31 and 31' of the opening mandrel 30, the partitions 25 and 25 'of the two half-shells 1 and 2, whereby the components respectively through the corresponding passageway 32 and 32' in the mixing element 9 can get. The displacement of the discharge pipe 23 can be done by inserting the mixing element 9. In order to ensure a secure fit of the mixing element 9 in the discharge tube 23 during the squeezing of the container, the mixing element 9 at its in FIG. 10 right end latching lugs 34 or the like. For engagement in corresponding latching openings or locking grooves 35 on the discharge pipe 23. By this latching connection is prevented that the mixing element 9 is pressed by the pressure arising during the expression of the components from the discharge pipe 23. The locking connection can also be provided at other suitable locations, as well as other than the locking connection or clamping means shown here can be used.

That in the FIGS. 11 and 12 schematically shown sixth example of a multi-component film container differs from the fifth example only by the configuration of the neck 27 and in that the discharge pipe 23 is placed on the storage part 24 only before the use of the container. Corresponding parts are therefore also provided with the same reference numerals. The container is in FIG. 11 left and in FIG. 12 shown above with the applied applicator tube 23 in a first position prior to piercing the seal, while FIG. 11 right and FIG. 12 below shows a second position after piercing.

The cross-sectionally circular neck 27 of the storage part 24 has two axially offset, outwardly projecting shoulders 37 and 38, which can engage over the inwardly projecting annular web 28 on the attachment piece 26. In contrast to the fifth example, here partition walls 36 and 36 'for separating the chambers 5 and 5' from the discharge channel 6 at the front end of the neck 27 are arranged. The first shoulder 37 holds when placed the attachment piece 26 in a first position in which the partitions 36 and 36 'are not pierced. In order to be able to pierce the partitions 36 and 36 'after fitting the attachment piece 26, the attachment piece 26 is displaceable in the direction of the chambers 5 and 5' on the neck 27, wherein the first shoulder 37 prevents undesired removal of the attachment piece 26 during the piercing , To secure the attachment piece 26 in the in FIG. 11 right and in FIG. 12 To keep the position shown below, the annular web 28 is pushed over the second shoulder 38.

In both FIGS. 13 and 14 Container arrangements are shown with several multi-component film containers according to the first two examples. The individual multi-component film containers are connected to one another via connection points 39 on the side edges of their respective storage regions 3, wherein the connection points 39 are designed as predetermined breaking points in order to separate the individual containers before use easily and without damage.

In the exemplary embodiments shown here, the two chambers 5 and 5 'each have the same volume, so that a mixing ratio of the components of 1: 1 at Expressing the two chambers 5 and 5 'is generated. By adjusting the chamber sizes, any other mixing ratios can be achieved. For example, B. the chamber 5, only half the volume as the chamber 5 ', so a mixing ratio of 1: 2 can be achieved.

Preferably, the chambers contain a volume of 0.5 to 10 ml. For larger quantities, the chambers may preferably be formed longitudinally and with a lower height than in the embodiments described above. At the end of the multi-component film container facing away from the discharge opening, a rod-shaped and perpendicular to the surface extension of the container rotatable squeezing device can then be arranged in order to then roll up the then substantially tube-shaped container from the exit opening facing away from the end of the container and thereby a uniform as possible squeezing the To achieve components through the discharge channel and the mixing element arranged therein.

The in the FIGS. 15 to 17 schematically shown first inventive further multi-component film container differs from that in the Figures 1 and 2 embodiment shown essentially in that between the discharge channel 6 and the chambers 5 and 5 ', a connecting channel 40 is formed through which a guide channel 41 of the mixing element 9 extends into the chambers 5 and 5'. Both chambers 5 and 5 'are each sealed by their own release film 12 and 12', which are the output side adapted to the shape of the guide channel 41. To open the release films 12 and 12 ', the discharge channel 6 in the region of the connecting channel 40 is bent upwards and downwards, so that the rear, extended end of the mixing element 9, the release films 12 and 12' with serving as opening mandrels webs 42 and 43rd pierces. By pressing the chambers 5 and 5 'then the components can pass through the connecting channel 40 in the discharge channel 6, wherein the guide channel 41 ensures that the components tile without much pressure loss in the mixing element 9, in which they are mixed. The multi-component film container has in addition at its rear end on an opening 44, through which it in a in the WO 2006/079413 A2 shown ejection device can be fixed.

One in the FIGS. 18 to 22 schematically shown second embodiment of a multi-component film container according to the invention differs from the above embodiments, especially in that the two chambers 5 and 5 'in the upper second half-shell 2 are formed side by side and sealed by a single release film 12. Therefore, the discharge channel 6 at its the chambers 5 and 5 'facing ends and two connecting channels 45 and 46 in order to direct the components of the respective chamber 5 and 5' in the discharge channel 6 can. At its rear end, the multi-component film container has two openings 47 and 48, through which he in a in the WO 2006/079413 A2 shown ejection device can be fixed.

In the in the FIGS. 18 to 22 shown multi-component film container, the discharge channel 6 is formed as a gutter-shaped bulge both in the upper, the chambers 5 and 5 'containing upper second half-shell 2 and in the lower first half-shell 1. In the FIG. 22 shown semi-annular extension of the discharge channel 6 is formed exclusively in the lower first half-shell 1 and opens with their ends in the chambers 5 and 5 ', so that connecting channels 45 and 46 form. This in FIG. 20 shown mixing element 9 is adapted to the shape of the discharge channel 6 and the adjoining connecting channels 45 and 46 and also has a semi-annular extension with two guide channels 49 and 50, in which on the release film 12 side facing two openings 51 and 52 are formed. To open the release film 12, the discharge channel 6 is bent upwards and downwards, so that the serving as opening mandrels edges 53 and 54 of the guide channels 49 and 50, the release film 12 break open. The components can then flow through the openings 51 and 52 into the guide channels 49 and 50 as well as the connection channels 45 and 46 and further into the discharge channel 6.

In the FIGS. 23 to 27 a third embodiment of a multi-component film container according to the invention is shown, which differs from the in FIGS. 18 to 22 shown essentially differs in that the discharge channel 6 and connecting channels 55 and 56 are formed by trough-shaped bulges exclusively in the upper second half-shell 2. The connecting channels 55 and 56 are also formed here by a semi-annular extension of the discharge channel 6 and open with their ends to the chambers 5 and 5 '. On the mixing element 9 turn guide channels 57 and 58 are arranged with an adapted to the semi-annular extension of the discharge channel 6 form. In addition, the mixing element 9 has a flat bottom, so that it is in the inserted state is flush with the flat bottom of the upper second half-shell 2, as in FIG. 26 recognizable. The sealing release film 12 is attached to the upper second half-shell 2 so that the ends of the guide channels 57 and 58 on the outside of the release film 12 lie in the chambers 5 and 5 '. Since the chambers 5 and 5 ', the connecting channels 55 and 56 and the discharge channel 6 are formed exclusively in the upper second half-shell 2, the lower first half-shell 1 may consist of a flat cover foil ( FIG. 27 ). As a result, the production-technically complex shaping of both films is avoided, whereby the production of the multi-component film container is simplified. As with the execution after the FIGS. 18 to 22 For the purpose of opening the release film 12, the discharge channel 6 is bent upwards and downwards, so that edges 59 and 60 of the guide channels 57 and 58 serving as opening mandrels break open the release film 12. The components can then flow directly into the discharge channel 6 through the guide channels 57 and 58 and the connection channels 55 and 56.

In the FIGS. 28 to 31 a fourth embodiment of a multi-component film container according to the invention is shown, which is a combination of the multi-component film container with opposite chambers 5, 5 'according to the FIGS. 15 to 17 and the separate guide channels of the mixing elements 9 from the FIGS. 20 to 27 represents.

The multi-component foil container after the FIGS. 28 to 31 has two half-shells 1 and 2, in each of which a chamber 5 or 5 'and the discharge channel 6 forming channel-shaped bulges 94 and 95 are formed. The channel-shaped protrusions 94 and 95 are S-shaped in the direction of the chambers 5 and 5 'extended, which recede in this area to the rear. How out FIG. 28 As can be seen, the S-shaped portion of the bulge 94 and an extended portion 96 of the chamber 5 'are arranged side by side, that when juxtaposing the identical half-shells 1 and 2, the S-shaped bulges 95 and 94 of a half-shell respectively with the extended portions 96 (shown in the upper half-shell 2 diagrammatically) of the other half-shell to overlap. The chambers 5 and 5 'are each sealed by their own release film 12 or 12', which release the channel-shaped bulges 95 and 94 ( FIGS. 29 and 30 ).

The channel-shaped bulges 94 and 95 respectively form connection channels 97 and 98 (in FIG Fig. 29 shown only for the lower half-shell 1) to the discharge channel 6, wherein the mixing element 9 is adapted to the shape of the discharge channel 6 and the connecting channels 97 and 98. For this purpose, the mixing element 9 has at its rear end two S-shaped guide channels 99 and 100 forming a fork-shaped extension, wherein the in Fig. 31 upper guide channel 99 comes to lie in assembled multi-component foil container in the connecting channel 97 of the upper second half-shell 2, while the lower guide channel 100 in the connecting channel 98 of the lower first half-shell 1 comes to rest.

The ends of the guide channels 99 and 100 are like the mixing element 9 from Fig. 17 serving as opening mandrels webs 101, 102 and 103, 104. To open the release films 12 and 12 ', the discharge channel 6 in the region of the S-shaped bulges 95 and 94 up and down kinked so that the webs 101, 102 of the upper guide channel 99, the release film 12 of the lower chamber 5 open while the webs 103, 104 of the lower guide channel 100, the release film 12 'of the upper chamber 5' open.

By subsequently pressing the chambers 5 and 5 ', the components can then reach the discharge channel 6 via the connection channels 97 and 98 and the guide channels 99 and 100, respectively.

The multi-component film container has additionally at its rear end a T-shaped extension 105, to better grip it by hand or in the in the WO 2006/079413 A2 to be able to fix and express the expressing device shown.

As is apparent from the above description, by the insertable into the discharge channel 6 separate mixing element 9, the components in expressing the multi-component film container can be mixed particularly effectively. The expressions can be done by hand or by means of in the WO 2006/079413 A2 shown ejection devices, which in particular allow to obtain a consistently homogeneous mixture.
