Description:
FIELD OF THE INVENTION 
       [0001]    The invention relates to a multicomponent foil type container. The invention further relates to a container arrangement with several such multicomponent foil type containers and also to a squeezing device for a multicomponent foil type container. 
       BACKGROUND OF THE INVENTION 
       [0002]    A multicomponent foil type container of this class is known from U.S. Pat. No. 4,952,068. There the multicomponent foil type container is formed by two relatively thin and flexible plastic films, which border a first and a second chamber for accommodating the two different components of a two-component adhesive. Both chambers have outlet openings in a mixing area, wherein the components are held back in an unmixed state by separating films in the chambers before use. For squeezing out the components, the container is pressed together in the area of the chambers, so that the separating films break open and the two components are led into the mixing area. Deflection elements, by means of which the two components are mixed with each other and which are formed on the container films, are arranged in the mixing area. A discharge area with an outlet opening for the component discharge connects to the mixing area. Due to the deflection elements formed on the container films, however, the possible constructions of the mixing structures are limited, so that a relatively large mixing volume is required for achieving effective mixing. In addition, due to the limited embodiments of such a mixer, very long flow paths are required for the components to be mixed, in order to achieve adequate mixing, which results in high squeezing resistance. In addition, the deflection elements are tailored to certain components and fields of use and cannot be modified without additional means. 
         [0003]    The problem of the present invention is to specify a multicomponent foil type container and a container arrangement of the type named above, which can be produced easily and which also allow a particularly effective mixing of different components. Furthermore, the invention should specify a squeezing device for the multicomponent foil type container, which allows effective mixing of the components. 
       SUMMARY OF THE INVENTION 
       [0004]    This problem is solved by a multicomponent foil type container with the features of Claim  1 , a container arrangement with the features of Claim  31 , and also by a squeezing device with the features of Claim  33 . Advantageous constructions and preferred improvements of the invention are specified in the subordinate claims. 
         [0005]    For the multicomponent foil type container according to the invention, significantly more complex deflection elements and mixing structures can be realized by the separate mixing element, whereby particularly efficient mixing is allowed. The seal of the chambers of the multicomponent foil type container can be opened easily by the elongated end of the mixing element facing the chambers and the one or more opening pins arranged on this mixing element for opening the one or more seals. In comparison with conventional multicomponent containers of this type, the components need not be pre-mixed by squeezing them back and forth several times in order to achieve good mixing. The separate mixing element allows a particularly effective construction and arrangement of the deflection element, whereby the mixing volume is also reduced. The short flow paths in the mixer and the compact mixer structure allow easy squeezing of the components. The handling of the multicomponent foil type container is extremely simple and requires no complicated preparations. The container merely must be pressed together in the area of the two chambers by hand, whereby the two components are forced through the mixing element and mixed there without a great expenditure of force. Due to the separate mixing element, the multicomponent foil type container can also be adapted relatively easily to different requirements and components. According to the type and properties of the components, a suitable mixer can also be selected without large production-specific changes either during production or also just before use. 
         [0006]    In a particularly advantageous construction, the chambers are constructed in two half-shells, which are produced from a flexible but nevertheless dimensionally stable material. The two half-shells can be filled easily and then assembled together. The dimensionally stable material can prevent the chambers from bulging out during the pressing process, so that the entire applied pressure is available for pressing the components out of the chambers into the discharge duct. 
         [0007]    For a simple construction in terms of production, the discharge duct is formed by two groove-shaped indentations in the two half-shells. The chambers for storing the components, however, can also be arranged in a separate storage part and the discharge duct can be arranged in a discharge tube that can be attached to the storage part. In this way, discharge tubes with different mixing elements can be provided for different components. 
         [0008]    The seal for preventing mixing of the components before use can be formed by one or more separating films arranged between the two chambers. The seal, however, can also be formed by separating crosspieces or separating walls between the chambers and the discharge duct. 
         [0009]    For squeezing out and mixing the components, the seal can be destroyed or opened by means of pressure from the outside or separate opening elements. The opening elements can be constructed, e.g., as opening pins, which are arranged on the half-shells and/or the mixing element and/or the discharge tube. 
         [0010]    For other preferred embodiments, the opening, pins can also be arranged on the attachable discharge tube or on the half-shells. 
         [0011]    In another embodiment, the mixing element is arranged so that it is movable in the discharge duct in the longitudinal direction of this duct, in order to be able to open the seal through the movement of the mixing element in the direction of the chambers.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0051]    The multicomponent foil type container shown in  FIG. 1  has a lower half-shell  1  shown separately in  FIG. 2  and also an identically shaped upper half-shell  2 , which is produced from a dimensionally stable plastic film through a deep-drawing or thermo-forming method and which are tightly connected to each other through a welding or adhesion method. The multicomponent foil type container is divided in terms of function into a storage area  3  for the accommodation 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 multicomponent foil type container there are two chambers  5  and  5 ′, which are formed by bulges in the respective half-shells  1  and  2  and which are separated from each other by a separating film  12 . The mixing area  4  contains a discharge duct  6 , which is open at the front end and which is formed by groove-shaped indentations  7  and  7 ′ in the two half-shells  1  and  2 . The two groove-shaped indentations  7  and  7 ′ are separated from the chambers  5  and  5  by separating crosspieces  8  and  8 ′, respectively, and are shaped such that the discharge duct  6  bounded by it has a square or rectangular cross section over nearly the entire length. Only at the front end are the indentations  7  and  7 ′ shaped so that they form a short discharge nozzle with a circular round discharge opening. A mixing element  9  shown in  FIG. 2  is arranged in the discharge duct  6 . 
         [0052]    In  FIG. 2 , only the lower of the two identically constructed half-shells are shown. As emerges from  FIG. 2 , the chamber  5  is separated from the groove-shaped recess  7  by the separating crosspiece  8 . The mixing element  9  produced from a dimensionally stable plastic, e.g., in an injection-molding method, is inserted into the groove-shaped recess  7 . The mixing element  9  shown here has a base body  10  with angled crosspieces  11  formed on this body and openings. The crosspieces  11  are angled in different directions, so that a particularly effective deflection and mixing of the components is produced. The mixing element  9  can also have a different construction according to the purpose of the application or use. Thus, the mixing element, e.g., can also be round or conical and can have a spiral-shaped mixing structure. 
         [0053]    The separating film  12 , which is indicated only schematically in  FIG. 1  and which is attached to one or also to both of the previously filled half-shells  1  and  2  before filling the two chambers  5  and  5 ′, is arranged between the two half-shells  1  and  2  before these are then placed one on top of the other and tightly connected to each other. The separating film or films  12  form a seal, by means of which it is guaranteed that the two components located in the chambers  5  and  5 ′ do not mix with each other before use. 
         [0054]    To discharge the two components from the multicomponent foil type container, the two half-shells  1  and  2  are pressed together by hand in the area of the chambers  5  and  5 ′. The separating film  12  is constructed such that it is lifted from the chambers  5  and  5 ′ by the pressure generated within the chambers  5  and  5 ′ when the half-shells  1  and  2  are pressed together in the area of the separating crosspieces  8  and  8 ′ of the half-shells  1  and  2  and allows an outlet of the components from the chambers  5  and  5 ′. The separating crosspieces  8  and  8 ′ are also designed so that they are pressed apart from each other at a predetermined point by the emerging components and form a passage from the chambers  5  and  5 ′ to the discharge duct  6 . In this way, the components can be led into the discharge duct  6  and through the mixing element  9  to the discharge opening. Here, the two components are mixed with each other and the adhesive or the like can be discharged immediately at a desired position. 
         [0055]    The second embodiment of a multicomponent foil type container shown schematically in  FIGS. 3 and 4  differs from the first embodiment only by the construction of the mixing element  9 . Corresponding parts are therefore also provided with the same reference symbols. In the construction shown here, the mixing element  9  is displaceably arranged in the longitudinal direction within the discharge duct  6  and a shaped opening pin  13  with two points on its interior end facing the chambers  5  and  5 ′. A plunger  14  projecting outwards from the discharge duct  6  is formed at the other end of the mixing element  9 . 
         [0056]    To connect the chambers  5  and  5 ′ to the discharge duct  6 , the mixing element  9  is pressed in the direction of chambers  5  and  5 ′ by hand with the aid of the plunger  14 , so that the tips of the opening pin  13  are pushed between the separating crosspieces  8 ,  8 ′ of the two half-shells  1  and  2  and in this way the separating crosspieces  8  and  8 ′ are spread apart from each other for forming a passage. In addition, the separating film or films  12  are lifted from the half-shells  1  and  2  by the tips of the opening pin  13 , so that the components can be pressed from the chambers  5  and  5 ′ into the discharge duct  6  and towards the discharge opening by the mixing element  9 . So that the mixed components can also be discharged through the discharge opening the plunger  14  can be rotated about its longitudinal axis after pushing it into the mixing element  9  and pulling it back into its original position, and in this way it is detached from the mixing element  9 . 
         [0057]    The third embodiment shown in  FIGS. 5 and 6  differs from the previously mentioned constructions essentially in that the groove-shaped indentations  7  and  7 ′ have inclined parts  15  and  15 ′, respectively, elongated on the chamber-side end and arranged next to an area  16  and  16 ′ of the chambers  5  and  5 ′, respectively, elongated towards the front. As follows from  FIG. 6 , the inclined part  15  of the indentation  7  and the chamber  5  are arranged one next to the other with its elongated area  16  so that the inclined parts  15  and  15 ′ of one hall-shell each overlap the elongated areas  16  and  16 ′ of the other half-shell when the identical half-shells  1  and  2  are placed one on top of the other. Opening pins  17  and  17 ′, which can be pressed from the outside, which project inwards, and which can be made to pierce through the separating film or films  12  arranged between the half-shells  1  and  2  by hand without damaging the outer skin of the container, are arranged on the two inclined parts  15  and  15 ′. 
         [0058]    In the fourth embodiment shown in  FIGS. 7 and 8 , a separate discharge tube  18  with the discharge duct  6  arranged therein is provided. The discharge tube  18  can be set on a separate storage part  19  of the multicomponent foil type container at this point. The storage part  19  is here composed 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 also here filled with different components. The seal is realized here by a separating film  12  arranged between the half-shells  1  and  2  and by a front separating wall  21  of the half-shells  1  and  2 . The chambers  5  and  5 ′ are separated from the discharge duct  6  of the discharge tube  18  before use by the front separating walls  21  of the two half-shells  1  and  2 . The discharge tube  18  can be connected to the storage part  19  sealed from the outside by means of a sleeve-shaped attachment part  20 . To connect the chambers  5  and  5 ′ to the discharge duct  6 , the separating walls  21  of the half-shells  1  and  2  must be pierced. For this purpose, an opening pin  22  with two points is formed on the chamber-side end of the mixing element  9  in the discharge tube  18 . The front separating walls  21  of the storage part  19  are pierced by the two tips of the opening pin  22  when the discharge tube  18  is attached, so that the components can be led into the discharge duct  6  of the discharge tube  18 . 
         [0059]    In the fifth embodiment shown in  FIGS. 9 and 10 , a discharge tube  23  is attached to a storage part  24  displaceable in the longitudinal direction. The storage part  24  is composed, in turn, from two identical half-shells  1  and  2 , in which the chambers  5  and  5 ′ formed from indentations are constructed. Here, the two chambers  5  and  5 ′ are also separated from each other by a separating film or films  12  arranged between the half-shells  1  and  2 . Within the half-shells  1  and  2  there are separating walls  25  and  25 ′, which prevent the discharge of the components into the discharge duct  6  before use. The discharge tube  23  is constructed for this configuration such that the mixing element  9  can be inserted from the discharge opening into the discharge duct  6 . 
         [0060]    As shown in  FIG. 10 , the discharge tube  23  is attached by means of a hollow cylindrical attachment piece  26  onto a throat  27  of the storage pan  24  with a round cross section displaceable in the longitudinal direction. The axial displacement of the discharge tube  23  is limited towards the front by an annular crosspiece  28  projecting inwards on the attachment piece  26  and a corresponding shoulder  29  on the throat  27 . The discharge tube  23  has an opening pin  30  with two separate points  31  and  31 ′ arranged within the attachment piece  26  for piercing the two separating walls  25  and  25 ′. In the two points  31  and  31 ′ there are passage channels  32  and  32 ′ for the two components. In  FIG. 10 , the openings  33  can also be seen in the mixing element  9 . 
         [0061]    By pushing the discharge tube  23  in the direction of the chambers  5  and  5 ′, the points  31  and  31 ′ of the opening pin  30  pierce the separating walls  25  and  25 ′ of the two half-shells  1  and  2 , whereby the components can each be led through the corresponding passage channel  32  and  32 ′, respectively, into the mixing element  9 . The discharge tube  23  can be displaced by attaching the mixing element  9 . To guarantee a secure seating of the mixing element  9  in the discharge tube  23  during the squeezing of the container, the mixing element  9  has catch tabs  34  or the like at its right end in  FIG. 10  for engaging in corresponding catch openings or catch grooves  35  on the discharge tube  23 . This catch connection prevents the mixing element  9  from being pressed from the discharge tube  23  by the resulting pressure when the components are squeezed out. The catch connection can also be provided at different suitable position. Catch connection or clamping means that are different from those shown here can also be used similarly. 
         [0062]    The sixth embodiment shown schematically in  FIGS. 11 and 12  for a multicomponent foil type container differs from the fifth embodiment only by the construction of the throat  27  and in that the discharge tube  23  is first attached to the storage part  24  before the container is used. Corresponding parts are therefore also provided with the same reference symbols. The container is shown in  FIG. 1  at the left and in  FIG. 12  at the top with the attached discharge tube  23  in a first position before the seal is punctured, while a second position after the puncturing is shown in  FIG. 11  at the right and in  FIG. 12  at the bottom. 
         [0063]    The round cross-sectional throat  27  of the storage part  24  has two shoulders  37  and  38 , which are offset in the axial direction and which project outwards and which can surround the inward projecting annular crosspiece  28  on the attachment piece  26 . In contrast to the fifth embodiment, here separating walls  36  and  36  are arranged on the front end of the throat  27  for separating the chambers  5  and  5 ′ from the discharge duct  6 . When attached, the first shoulder  37  holds the attachment piece  26  in a first position, in which the separating walls  36  and  36 ′ have not yet been pierced. To be able to pierce the separating walls  36  and  36 ′ after placing the attachment piece  26 , the attachment piece  26  is displaceable in the direction of the chambers  5  and  5 ′ on the throat  27 , wherein the first shoulder  37  prevents undesired pulling of the attachment piece  26  during the piercing. To hold the attachment piece  26  reliably in the position shown in  FIG. 11  at the right and in  FIG. 12  at the bottom during the squeezing out of the components, the annular crosspiece  28  is pushed by means of the second shoulder  38 . 
         [0064]    In the two  FIGS. 13 and 14 , holder arrangements with several multicomponent foil type containers according to the first two embodiments are shown. The individual multicomponent foil type containers are connected to each other by means of connection points  39  at the side edges of their respective storage areas  3 , wherein the connection points  39  are constructed as desired rupture points, in order to be able to separate the individual containers from each other easily and without damage before use. 
         [0065]    In the 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 is generated when the two chambers  5  and  5 ′ are squeezed. By changing the chamber sizes, any mixing ratio can be achieved. For example, if the chamber  5  has only half the volume of the chamber  5 ′, then a mixing ratio of 1:2 can be achieved. 
         [0066]    Preferably, the chambers contain a volume from 0.5 to 10 ml. For larger quantities, the chambers can preferably have an elongated shape with a smaller height than in the previously described embodiments. Then a rod-shaped squeezing device that can rotate perpendicular to the area extent of the container can be arranged at the end of the multicomponent foil type container facing away from the discharge opening, in order to be able to roll up the essentially tubular container from the end of the container facing away from the discharge opening, and in this way achieve the most uniform possible squeezing process of the components through the discharge duct and the mixing element arranged therein. 
         [0067]    The additional multicomponent foil type container shown schematically in  FIGS. 15 to 17  differs from the construction shown in  FIGS. 1 and 2  essentially in that a connection channel  40 , through which a guide channel  41  of the mixing element  9  reaches into the chambers  5  and  5 ′, is formed between the discharge duct  6  and the chambers  5  and  5 ′. Both chambers  5  and  5 ′ are each sealed by its own separating film  12  and  12 ′, respectively, which are adapted on the output side to the shape of the guide channel  41 . For opening the separating films  12  and  12 ′, the discharge duct  6  is bent up and down in the area of the connection channel  40 , so that the rear, elongated end of the mixing element  9  pierces the separating films  12  and  12 ′, respectively, with the crosspieces  42  and  43  used as opening pins. By pressing the chambers  5  and  5 , the components can then be led via the connection channel  40  into the discharge duct  6 , wherein the guide channel  41  provides that the components flow without large pressure loss into the mixing element  9 , where they are mixed. The multicomponent foil type container also has at its rear end an opening  44 , through which it can be fixed in a squeezing device explained below in more detail. 
         [0068]    An additional construction of a multicomponent foil type container shown schematically in  FIGS. 18 to 22  differs from the preceding constructions primarily in that the two chambers  5  and  5 ′ are formed one next to the other in the upper second half-shell  2  and are sealed by a single separating film  12 . Therefore, the discharge duct  6  also has two connection channels  45  and  46  on its end facing the chambers  5  and  5 ′, in order to be able to guide the components from the respective chamber  5  or  5 ′ into the discharge duct  6 . At its rear end, the multicomponent foil type container has two openings  47  and  48 , by which means it can be fixed in a squeezing device (to be explained below in more detail). 
         [0069]    In the multicomponent foil type container shown in  FIGS. 18 to 22 , the discharge duct  6  is formed as a groove-shaped indentation both in the upper upper [sic] second half-shell  2  containing the chambers  5  and  5 ′ and also in the lower first half-shell  1 . The half-annular extension of the discharge duct  6  shown in  FIG. 22  is formed exclusively in the lower first half-shell  1  and opens with its ends into the chambers  5  and  5 ′, so that connection channels  45  and  46  are formed. The mixing element  9  shown in  FIG. 20  is adapted to the shape of the discharge duct  6  and the connection channels  45  and  46  connected to this duct and likewise has a half-annular extension with two guide channels  49  and  50 , in which two openings  51  and  52  are formed on its side facing the separating film  12 . To open the separating film  12 , the discharge duct  6  is bent up and down, so that the edges  53  and  54  used as opening pins in the guide channels  49  and  50  break open the separating film  12 . The components can then flow through the openings  51  and  52  into the guide channels  49  and  50  and also the connection channels  45  and  46  and further into the discharge duct  6 . 
         [0070]    In  FIGS. 23 to 27 , another construction of a multicomponent foil type container is shown, which differs from that shown in  FIGS. 18 to 22  essentially in that the discharge duct  6  and connection channels  55  and  56  are formed by groove-shaped indentations exclusively in the upper second half-shell  2 . The connection channels  55  and  56  are here formed by a half-annular extension of the discharge duct  6  and open with their ends to the chambers  5  and  5 ′ Guide channels  57  and  58  with a shape adapted to the half-annular extension of the discharge duct  6  are arranged, in turn, on the mixing element  9 . In addition, the mixing element  9  has a flat bottom side, so that it connects flush with the flat bottom side of the upper second half-shell  2  in the inserted state, as can be seen in  FIG. 26 . The sealing separating film  12  is attached to the upper second half-shell  2  so that the ends of the guide channels  57  and  58  lie on the outer side of the separating film  12  in the chambers  5  and  5 ′. Because the chambers  5  and  5 ′, the connection channels  55  and  56 , and the discharge duct  6  are formed exclusively in the upper second half-shell  2 , the lower first half-shell  1  can be composed of a flat cover film ( FIG. 27 ). In this way, the shaping of both films, which is complicated in terms of production, is avoided, whereby the production of the multicomponent foil type container is simplified. Just as for the construction according to  FIGS. 18-22 , to open the separating film  12 , the discharge duct  6  is bent up and down, so that the edges  59  and  60  of the guide channels  57  and  58  used as opening pins break open the separating film  12 . The components can then flow directly through the guide channels  57  and  58  and also the connection channels  55  and  56  into the discharge duct  6 . 
         [0071]    In  FIGS. 28-31 , another construction of a multicomponent foil type container is shown, which essentially shows a combination of the multicomponent foil type container with opposing chambers  5 ,  5 ′ from  FIGS. 15 and 17  and the separate guide channels of mixing elements  9  from  FIGS. 20-27 . 
         [0072]    The multicomponent foil type container according to  FIGS. 28-31  has two half-shells  1  and  2 , in which a chamber  5  and  5 ′, respectively, and the groove-shaped indentations  94  and  95 , respectively, forming the discharge duct  6  are constructed. The groove-shaped indentations  94  and  95  are extended in the shape of an S in the direction of chambers  5  and  5 ′, respectively, which recede towards the back in this area. As emerges from  FIG. 28 , the S-shaped part of the indentation  94  and an extended area  96  of the chamber  5 ′ are arranged one next to the other such that when the identical half-shells  1  and  2  are placed one on top of the other, the S-shaped indentations  95  and  94 , respectively, of one half-shell overlap the extended areas  96  (only shown illustratively in the upper half-shell  2 ) of the other half-shell. The chambers  5  and  5 ′ are each sealed by its own separating film  12  and  12 ′, respectively, which open the groove-shaped indentations  95  and  94 , respectively ( FIGS. 29 and 30 ). 
         [0073]    The groove-shaped indentations  94  and  95  each form connection channels  97  and  98 , respectively, (in  FIG. 29  only shown for the lower half-shell  1 ) to the discharge duct  6 , wherein the mixing element  9  is adapted to the form of the discharge duct  6  and the connection 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 upper guide channel  99  in  FIG. 31  comes to lie in the connection channel  97  of the upper second half-shell  2  when the multicomponent foil type container is assembled, while the lower guide channel  100  comes to lie in the connection channel  98  of the lower first half-shell  1 . 
         [0074]    The ends of the guide channels  99  and  100  have crosspieces  101 ,  102  and  103 ,  104 , respectively, used as opening pins like the mixing element  9  from  FIG. 17 . To open the separating films  12  and  12 ′, the discharge duct  6  is bent up and down in the area of the S-shaped indentations  95  and  94 , respectively, so that the crosspieces  101 ,  102  of the upper guide channel  99  open the separating film  12  of the lower chamber  5 , while the crosspieces  103 ,  104  of the lower guide channel  100  open the separating film  12 ′ of the upper chamber  5 ′. 
         [0075]    Through subsequent pressing on the chambers  5  and  5 ′, the components can then be led into the discharge duct  6  via the connection channels  97  and  98 , respectively, and the guide channels  99  and  100 , respectively. 
         [0076]    The multicomponent foil type container also has at its rear end a T-shaped extension  105 , in order to be able to better grip it by hand or to be able to fix and squeeze it in the squeezing device shown in  FIGS. 32-35 . 
         [0077]    As emerges from the description above, the components can be particularly effectively mixed by the separate mixing element  9  that can be inserted into the discharge duct  6  when the multicomponent foil type container is squeezed. Squeezing is performed by hand or a uniformly homogeneous mixture is obtained by means of the squeezing devices shown in  FIGS. 32-38 . 
         [0078]    The first squeezing device shown in  FIGS. 32-35  is used for squeezing a multicomponent foil type container shown in  FIG. 15-17  or  28 - 31  with chambers  5  and  5 ′ lying opposite each other. 
         [0079]    The first squeezing device is essentially composed of a holding element  61 , in which the multicomponent foil type container from  FIGS. 15-17  is pushed forward. For this purpose, the holding element  61  has two side guides  62  and  63  that lie opposite each other and that have circular guide grooves  64  and  65 , which are open on the inside and in which the side edges of the multicomponent foil type container can be pushed. To guarantee the spacing of the guides  62  and  63  and also the parallel orientation of the guide grooves  64  and  65 , the guides  62  and  63  spread out at their rear end and are there connected to each other by transverse connections  66  and  67 , respectively. 
         [0080]    To be able to squeeze the components out of the chambers  5  and  5 ′, two legs  68  and  69  are hinged on the rear end of the guides  62  and  63 . Because the legs are identically constructed, only the upper leg  68  is described. The upper leg  68  has an essentially rectangular frame structure  70 , which has a squeezing surface  71  on its lower side facing the chamber  5 . On the upper side, the frame structure  70  has a small recess. To attach the leg  68  to the holding element  61 , it has on its rear end a cylindrical pivot  72 , which spreads out at the outer end and which engages in a recess  73  open at the back and constructed as a catch connection in the extension of the guide  62 . The bearing of the leg  68  on the second guide  63  is realized in the same way, so that it can rotate about its two pivots and is secured against falling out by being supported on the side guides  62  and  63  of the holding element  61 . The second lower leg  69  in  FIGS. 32-35  is hinged rotatably on the guides  62  and  63  in an analogous way. To hold the legs  68  and  69  in an open position, a restoring spring  74  shown in detail in  FIGS. 33 and 34  is provided, which presses the two legs  68  and  69  apart from each other and against the transverse connections  66  and  67  used as stops. The restoring spring  74  here has the characteristic form shown in  FIGS. 33 and 34  and adapted to the squeezing device, in order to allow restoration with little expense, wherein other forms of restoring springs are conceivable without additional means. 
         [0081]    To squeeze an inserted multicomponent foil type container, first the separating films  12  and  12 ′ are opened by a single or repeated bending up and down of the discharge duct  6 . Then the two legs  68  and  69  of the squeezing device are pressed together with the thumb and index finger, so that the squeezing surfaces  71  and  71 ′ squeeze the components out of the chambers  5  and  5 ′ beginning from the rear end of the multicomponent foil type container. To guarantee a uniform and simultaneous squeezing of both chambers  5  and  5 ′, the legs  68  and  69  each have at the hinged ends two teeth, which are directed towards each other and which form toothing  75 , as can be seen especially from  FIG. 35 . In this way, when pressed together, both legs  68  and  69  remain with their squeezing surfaces  71  and  71 ′ each at the same absolute angle to the chambers  5  and  5 ′, respectively, so that a uniform mixture is performed and consequently a uniformly homogenous mixture can be generated. 
         [0082]    To hold the multicomponent foil type container securely in the squeezing device during the squeezing, the lower leg  69  has a holding pin  76  ( FIGS. 33 and 34 ), which points upwards and is curved towards the back and which engages constantly in the opening  44  at the rear end of the multicomponent foil type container during the squeezing. In this way, the multicomponent foil type container is specifically prevented from being pushed forwards out of the squeezing device due to the pressure exerted on the chambers  5  and  5 ′ by the legs  68  and  69 . 
         [0083]    The second squeezing device shown in  FIGS. 36-38  is used for squeezing a multicomponent foil type container shown in  FIGS. 18-27  with chambers  5  and  5 ′ lying one next to the other on the side. 
         [0084]    The second squeezing device has a holding element  77 , in which the multicomponent foil type container from  FIGS. 18-27  is pushed forward. For this purpose, the holding element  77  has a flat base  78  with two opposing side guides  79  and  80  that have circular guide grooves  81  and  82 , which are open on the inside and into which the side edges of the multicomponent foil type container can be pushed. The side guides  79  and  80  are connected to each other by a transverse crosspiece  83  at the front end in  FIG. 36 . As can be seen in  FIG. 37 , a fixing crosspiece  84 , which is fixed at the rear end of the holding element  77 , runs from the center of the transverse crosspiece  83  along the longitudinal side of the multicomponent foil type container. The fixing crosspiece  84  reaches into the area between the chambers  5  and  5 ′ of the multicomponent foil type container and represents an additional longitudinal guide. At the rear end of the holding element  77 , the guides  79  and  80  spread out in a wedge shape and are connected to each other at their upper ends by means of a transverse connection  85 . A leg  88  for squeezing the chambers  5  and  5 ′ is hinged by means of two articulation connections  86  and  87  at the extended sections. The articulation connections  86  and  87  are constructed in the same way as the hinge of the leg  69  on the guides  62  and  63  of the first squeezing device described above. 
         [0085]    The leg  88  has a frame structure with two squeezing surfaces  89  and  90 , which face the chambers  5  and  5 ′, which are visible in  FIG. 38  and which are connected to each other by a wide center crosspiece  91  running longitudinally. The center crosspiece  91  has a longitudinal slot  92 , in which the fixing crosspiece  84  is accommodated in the pressed-together state of the second squeezing device. 
         [0086]    As can be seen from  FIG. 38 , the base  78  of the holding element  77  has a recess  93 , which is adapted to the semicircular extension of the discharge duct  6  in the lower first half-shell  1  of the embodiment of the multicomponent foil type container shown in  FIGS. 18-22 , at its end facing the discharge duct of the multicomponent foil type container and at the front in  FIG. 38 . In this way, an additional center fixing and also a stop for the inserted multicomponent foil type container is provided. 
         [0087]    For squeezing a multicomponent foil type container inserted into the second squeezing device, the leg  88  is pressed, for example, with the thumb, against the holding element  77 , so that the squeezing surfaces  89  and  90  squeeze the components out of the chambers  5  and  5 ′ beginning from the rear end of the multicomponent foil type container. In this way, a uniform and simultaneous squeezing of the components from the chambers  5  and  5 ′ is reliably performed, so that toothing like that in the first squeezing device is unnecessary. 
         [0088]    The second squeezing device of  FIGS. 36-38  also has a restoring spring that cannot be seen in the drawings, in order to hold the leg  88  in an open position before inserting the multicomponent foil type container, wherein the transverse connection  85  is also used here as a stop for the leg  88 . To be able to fix the multicomponent foil type container during the squeezing, the leg  88  has two holding pins, which are not visible in the drawings and which engage in the openings  47  and  48  of the embodiment of the multicomponent foil type container shown in  FIGS. 18-27  during the squeezing process, at its hinged end on its lower side. In this way, undesired slipping of the multi-component foil type container from the second squeezing device is prevented. 
         [0089]    The invention is not limited to the constructions shown here. For example, the squeezing device can have clamping means at the rear end, in order to reliably fix the rear end of the multicomponent foil type container in the squeezing device during the squeezing process.
