Description

container

Description:

The invention relates to a bottle or bag-like container made of a plastic, in particular for foodstuffs, such as a baby bottle provided with a pacifier, and a method for filling this container in particular.

Baby bottles, made of glass or an unbreakable plastic, are known and proven for the administration of liquid baby food.

According to current practice, liquid baby food often consists of two components, a liquid and a powder phase. The baby bottle is heated with the liquid phase and then the powdered one is added. After mixing the two components, the baby food is ready, has the correct temperature and can be administered immediately.

The separate storage of two components of a baby food requires space and there is also a regular risk of contamination if larger portions are often taken out in individual portions. Handling a two-component baby food, for example on a trip, is also impractical. It is also known to weld liquids, for example milk or juices, into plastic tubes. For this purpose, in the case of an endless hose, a seam which closes an end face of a hose section is produced by separating welding, the section is filled and then closed by renewed separating welding and separated from the endless hose. Such hose packaging may be inexpensive and technically easy to fill, but it is mechanically unstable and tends to burst open. They can also only be parked open in appropriate holders and are therefore not very practical to use.

Against this technical background, it is the object of the invention to provide a container, for example a baby bottle, which avoids the disadvantages described, for which purpose in such a container, the aim is that at least one chamber is tearably separated from a second chamber.

In such a container according to the invention, at least two chambers are formed in this one container, which can be filled differently. After tearing open, after which essentially only one chamber is formed within the container, and the then possible mixing of the ingredients, a finished baby food is available, for example.

In a first constructive variant it can be provided that a chamber is separated from a second chamber by at least one seam. This means that the outer walls of the container are brought together and welded to one another, for example, which weld seam can be torn open, for example by increasing the pressure in one of the chambers by simply compressing them or by pulling apart opposite walls of the container, for which the container according to the invention must also have sufficient elasticity, but its stability should not suffer, for example, for sufficient stamina.

Alternatively, it can be provided that a chamber is separated from a second chamber by a membrane that can be torn open and / or torn off. Here, two chambers are separated from one another by a film or the like, for example, welded or glued into the container. It is also conceivable to form such a membrane in one piece with the container itself in the course of container production.

In a further constructive embodiment it can be provided that a chamber is separated from a second chamber by a boat-like molded part. As a rule, two tearable seams between the shaped parts and the opposite container walls are then expedient. Such a molded part can be used to increase the stability of a container according to the invention.

Furthermore, various combinations can be used for separating the chambers, for example the molded part can be arranged in a longitudinal extension between two seam sections.

A tearing open or tearing off of the seam, the membrane and / or the molded part is facilitated if it is designed in a side view or the membrane tapering from a larger chamber to a smaller chamber like a funnel, conical, rounded or the like. By squeezing the larger chamber, a maximum pressure will then build up in the direction of the funnel-like taper, which leads specifically to tearing and thus the possibility of mixing the contents of the at least two Chambers allowed. This effect can be enhanced by the measure if it is provided that the seam, the membrane and / or the boat-like molded part is arranged at a location of a locally smallest cross-section of the container.

More than two chambers can easily be separated from one another in this way, for example three chambers, an arrangement of the chambers axially one above the other being expedient in many cases. Intermediate floors are then formed, as it were, by the separating seams, membrane and / or molded parts.

Alternative design options provide that the chambers are arranged radially next to one another or sectorally next to one another. Misforms can also be formed.

With regard to baby food in particular, it is further provided that one chamber is filled with a powdered solid and another chamber is filled with a liquid. It will also be considered to fill a smaller upper chamber with the powdery component, for example, while the chamber axially underneath contains a liquid phase. The container according to the invention can then be bottle-shaped, for example formed with the lower chamber in conventional heating devices for baby bottles, and the liquid phase can be warmed up, after which the seam or membrane tears by pressing or pulling and the contents of the chambers are mixed together can be.

For the administration of baby food, it is further provided that an opening of a bottle-like container in a chamber is provided with a baby teat. In the case of a type of disposable bottle, this cannot be lost on the container tethered. The suction cup can, for example, be formed in one piece with the container or alternatively can be made separately from a suitable plastic material and can be glued or welded to the container covering the container opening.

Such a teat connected to the container will preferably be covered by a hood connected to the container for hygienic reasons. Such a hood, for example also formed in a film-like manner from a plastic, protects such a suction device against contamination. The hood can also at least form a guarantee closure, for example by being connected to the container by means of a plastic ring which can be torn open or torn off. In addition, it is useful if the hood closes a drinking opening of the vacuum cleaner.

Alternatively, it can be provided that a container opening has a thread for closing with a cap and / or a suction cup.

It has also proven to be advantageous if, when using an elastic plastic for the container according to the invention, an opening of a chamber is kept open by a dimensionally stable plastic ring, in particular when the container is formed by a film material. This ensures that a liquid can escape through the opening in any position of the container.

In the case of the container, it can further be provided that the plastic ring has at least one opening which is connected to a chamber via a tube. The individual chambers can then advantageously be filled via such tubes. Subsequently, the individual tubes are apparently only closed again.

In a preferred constructive embodiment, a tube passes through a boat-like molded part to which it is connected in a liquid-tight manner. As a result of this measure, a comparatively stable core is formed, formed by the plastic ring, the molded part and the tube, which in particular gives the container a high degree of buckling resistance if the tube still protrudes further at the end, inside the chamber to be filled by it. It is understood that sharp corners, edges or the like on the tubes, molded parts, plastic rings etc., which are suitable for damaging the walls of the container or a seam during transport, are avoided.

Such a stiffening can be further underlined by the measure if it is provided that a tube and / or a boat-like molded part has stiffening elements lying against the container walls.

Against the background of the use of the container according to the invention, it is further provided that the plastic is heat-resistant, food-safe and / or suitable for microwaves. The latter also just in case it warms up.

For some foods, it has also proven to be expedient if the container is provided with light protection, in particular against UV rays, for example a glued-on film or a corresponding coloring of the plastic. In the case of light-sensitive foods that have been brought in, for example, aging foods that are brought in under the sun's rays, this ensures a long possible storage time. In addition to light protection or alternatively, such a protective film, for example made of a PET material, can also protect the container contents Shield oxygen or specifically only against UV radiation and are also available as a carrier film for printing.

In a structural design of the container, it can be provided that it is made in several parts with a half-shell-like front and rear side made of a film-like plastic, which are glued and / or welded to one another in a liquid-tight manner at one edge and more preferably with a base part. For reasons of stability, the base part can, for example, be curved, in particular outwards, which also ensures a high level of stability of the container on the lower, if necessary. reinforced, protruding edges of the front or Back is given.

The formation of the edge can be such that it has a sufficient material thickness and the half-shells or the base part is formed so far above that this edge can have an integrated tool, for example an embossed or stamped spoon or the like.

Such an edge protruding from the half-shells or the base part can further serve to connect a large number of containers to one another. For example, a large number of interconnected half-shells can be embossed in one work step and with a corresponding counterpart and, if necessary, 1. welded to floors and / or glued. These containers, which are then finished, are expediently also jointly fed to a filling station and are only separated when necessary after filling.

In a preferred embodiment of the container according to the invention it can be provided that a front and / or a rear side and / or a base made of a multilayer plastic film exist, ^"in particular a composite film which is advantageously a co-extrudate. A simple and inexpensive manufacture of the container is thus given.

In this case, in particular, it is expedient for a layer of the plastic film pointing into the interior of the container to be made of a PE material with a peel component, arranged on a carrier layer and also made of a PE material. This enables easy and, in particular, reproducible tearing of bonded and / or welded contact surfaces of adjacent layers having peel components, and a seam is expediently formed here by two opposite, welded and / or bonded PE layers, each with a peel component. In addition, the force required for the tearing can be set reproducibly by the seam dimensions and also by parameters such as the temperature, the pressure applied and the duration of a weld and by the proportion of the peel component, for example to 2 N, 4 N or 8 N ,

In addition to these two layers, an outer lamination made of a PET material can also be applied to the film, which on the one hand offers a protective function against, for example, oxygen or light, in particular UV rays, and on the other hand can serve as a printing base. In this case, the print will usually be mirror-inverted on the back, the side of the PET film that lies against the PE layer without peel component, so that it cannot be damaged.

Two PE carrier layers and / or in particular two PET layers of a front and a rear side and / or a base part can be destroyed while at least destroying the one in between Layers of PE material with peel components can be welded and / or glued to one another in a liquid-tight manner on the edges. The force required to tear open such adhesive or weld seams corresponds essentially to that required to tear the film itself and is significantly higher than the force required to tear open a seam or a membrane. This ensures that a seam and no edge welding and / or gluing will tear open under pressure.

For the filling of a container which has at least two half-shells which are glued and / or welded to one another in a liquid-tight manner and which is designed in particular in the manner explained at the outset, it is assumed that the edge has at least one unsealed filling section for at least one chamber which the chamber is filled, and that the filling section is sealed after the chamber has been filled.

Filling is thus not carried out through a possibly provided pouring opening, but rather through specially provided filling sections which remain unsealed on the edge and which are closed, in particular glued and / or welded, only after filling. On the basis of this measure, a spout opening, if provided, can already be provided with a guarantee closure, for example, during the manufacture of the containers according to the invention.

It has further proven to be expedient if an edge strip having the filling sections, the half-shells and / or the base part is formed and that the edge strip is sealed after the

Filling section is separated from the container. With a comparatively wide edge strip there is hardly any the risk that a weld or adhesive seam connecting the half-shells and / or the base part will tear.

If, in particular, a broadly designed edge strip is provided, it is expedient if the filling section is widened to a filling opening before filling. A tube can then easily be inserted into a chamber for filling.

In a further embodiment of the method it can be provided that the edge is gripped on both sides of a filling section and widened to the filling section by shifting towards one another and, after filling, is closed by shifting in opposite directions, after which the filling section is sealed.

For gripping, grippers can be provided, for example, which hold the containers at the edge or, for example, the edge strips can be provided with openings into which movable bolts can be introduced, so that widening or reclosing for sealing the filling sections in can be done easily.

Furthermore, a chamber is preferably widened before filling, for example by blowing in a gas under pressure. So filling the chamber does not require excess pressure, but can only be done under atmospheric pressure and from above under the influence of gravity, even if filling under pressure has proven to be significantly faster. When filling under pressure, a chamber can also be filled completely, so that the container is also stiffened by the filling and remains largely dimensionally stable. Since the filling sections are preferably formed along an edge, the filling of several chambers can take place at the same time, which can further save considerable time.

This does not rule out the fact that, for filling several chambers, two particularly opposite edges have filling sections and that the container is preferably rotated once for filling all chambers from above.

The invention is explained in more detail with reference to the drawing, in which only exemplary embodiments are shown. The drawing shows:

Figure 1 shows schematically a bottle-like container according to the invention, in which a chamber 1 is tearably separated from a second chamber 2 along a line 3.

The two chambers created in this way can be filled differently, for example the first chamber 1 with a powdery material and the second chamber 2 with a liquid phase.

The tear-open separation of the first chamber 1 from the second chamber 2 can be done, for example, by a seam 4, see FIG. 3. It shows how the front 5 and the rear 6 of the container, which is made of an elastic plastic, can be torn together by the seam 4 are welded, for example.

Alternatively, it can be provided that a chamber is separated from a second chamber by a membrane that can be torn open and / or torn off, for which purpose such a membrane can also be glued to the front or rear side.

The bottle-like container of the first exemplary embodiment is made in several parts from a film-like plastic, see FIG. 4. The front 5 and rear 6 are embossed in the shape of a half shell, for example from the film-like plastic. A peripheral edge 7 or 8 is used for the liquid-tight gluing or welding of the two half-shells.

The container is closed on the underside by a film-like or comparatively dimensionally stable base part 9, which is also glued or welded in.

A sucker 11 is attached to an upwardly open neck 10. So that it is sufficiently secure and regularly widened like an opening 14, it is captively connected to a ring 12 made of a harder, non-deformable plastic.

The ring 12 is in turn welded or glued into the neck 10, see FIG. 2. Alternatively, a suction cup can also be formed in one piece with the container if the suction cup is kept open by a suitable geometry, for example by suitably introduced webs, flanges or the like.

On the ring 12, if necessary. Also on the neck 10, a hood 13 covering the suction device 11 is also arranged, so that when the container according to the invention is purchased, a hygienically perfect suction device 11 is ensured.

An alternative embodiment of a container 171 with a suction device 173 is shown in FIG. 46. In the exemplary embodiment, the suction device 173 is formed in one piece with a ring 172 which ensures an opening in a chamber 177, for example made of a dimensionally stable plastic. A hood 174 covering the suction cup 173 is also provided separately and attached to the suction cup 173. This approach is also covered, for example, by a completely circumferential plastic ring 175, which constitutes a guarantee closure, since the hood 174 can only be removed after this ring 175 has been irretrievably removed.

The hood 174 also serves for the liquid-tight closure of a suction opening 176 in the suction device 173.

Based on Figures 5 to 7 is another

Embodiment of a container according to the invention further explained, the construction of which largely corresponds to that of the first embodiment.

In the second exemplary embodiment, a membrane or a seam 15 in turn separates a first chamber 16 and a second chamber 17 from one another and the second chamber 16 can thus be a liquid phase and the liquid phase the first chamber 17 absorb a powdery phase, which can be mixed after the membrane or seam 15 has been torn open.

FIG. 6 further shows that the container according to the invention has two side regions 18, 19, which can be embossed, for example, in foil-like manner and are glued or welded at their edges 20, 21, a membrane or a seam 15, 15 'and one also separate bottom part 27 can be introduced.

The container according to the second exemplary embodiment has an opening 22 which is provided with a thread 23 which is usually closed by a cap 25. After the seam 15 or a membrane has been torn open and the contents of the containers have been mixed with one another, this cap 25 can be removed and, if necessary, after opening a guarantee closure for removal, a conventional suction device 24 according to FIG. Figure 7 are screwed on. 7 no longer shows the container being divided into two chambers in the vicinity of the arrow 28.

If the cap 25 is also provided with a thread, even after only partially emptying the container, it can then be sealed again for later, re-use.

The opening 22 is again stiff and unchangeable by a comparatively stable plastic ring 26.

A further exemplary embodiment is explained with reference to FIG. 8, in which three chambers 30, 31, 32 are separated from one another, as it were, by seams 33, 34 formed as intermediate floors. The chambers 30, 31, 32 are arranged axially one above the other. A safe tearing of the seams 33, 34 is through this arrangement is also ensured in the case of a plurality of chambers 30, 31, 32, since each chamber 30, 31, 32 can be subjected to pressure until it is torn open.

Otherwise, the structure of the container corresponds to the exemplary embodiments described above. Two embossed half-shells 35, 36, for example, form the front and rear of the container, for which purpose they are glued and / or welded together at edges 37, 38. A separately designed bottom part 39 ensures a secure stand, for which purpose this bottom part 39 in connection with the bottom edges 37, 38 has to be designed to be sufficiently dimensionally stable.

A rigid plastic ring 40 with an outlet opening 41 is bordered on the top by the edges 37, 38, the outer lateral surface of the ring 40 following an oval-shaped contour in a plan view.

Finally, a cap 42 is also provided, with which the outlet opening 41 can be closed again when the cap 42 has an internal thread for screwing onto an external thread 43 of a shaft 44 connected to the ring 40 and having the outlet opening 41.

Such a container with three chambers 30, 31, 32 can have, for example, a fruit pulp in the upper, smallest chamber 30, a fruit juice in the middle chamber of medium size and a dairy product in the lower, largest chamber 32, so that three, in particular liquid, at least creamy-liquid phases which can be easily mixed together after the seams 33, 34 have been torn open, for example by shaking or tumbling the container.

FIG. 9 shows a large number of containers 50, which are pre-assembled in a support frame consisting of four Holding arms 51 to 54 are held. If the containers 51 themselves are not sufficiently dimensionally stable, the support arms 51 to 54 can also engage in corresponding openings in the opposite edges 55, 56.

In the exemplary embodiment shown, the bag-like container 50 has an axially central, central chamber 57, to which further chambers 58, 59 lying radially on the outside are connected, the chambers 57-59 being detachably separated from one another by seams 60 and 61, respectively.

The upper edge 62 of the container 50 is not continuously closed by gluing and / or welding, but there remain three unsealed filling sections 63 to 65, through which the chambers 57 to 59 are filled, and which after the chambers 57 to 59 have been filled be closed, if necessary. also by a specially designed ring with a spout.

For the filling of a container 50, an individual container according to FIG. 10 is gripped by four grippers 66 to 69 on the upper edge 62 immediately next to the filling sections 63 to 65.

Sometimes. For example, openings can be provided in the upper edge 62 at these points, through which support arms pass, so that a plurality of containers 50 can be prepared or filled at once for filling.

The filling sections 63 to 65 according to FIG. 11 are preferably widened by moving the grippers towards one another, with the outside grippers 66, 69 first moving the outside filling sections 63, 65 by covering a path to the fixed inner grippers 67, 68. widen to fill openings and then together with the inside the lying grippers 67, 68 together and thus also expand the middle filling section 64 to a filling opening. Alternatively, the movement sequences of the grippers 66 to 69 can also be coupled and take place together.

If the filling sections 63 to 65 have been expanded in accordance with FIG. 11 and the chambers 57 to 59 have also preferably been expanded by blowing in compressed air, for example, according to FIG. 12, the chambers 57 to 59 can be simultaneously filled from above under the influence of gravity and under atmospheric pressure, but more quickly under Pressurization, which may be1. a separate expansion of the chambers 57 to 59 is unnecessary.

After the chambers 57 to 59 have been filled, the grippers 66 to 69 move apart again, as a result of which the widening is reversed and the edge 62 is stretched, see FIG. 13, so that the upper edge 62 is sealed, for example by a strip 70 placed thereon. which has long been overlapping the edge 62 is made possible. Alternatively, a direct sealing of the filling openings is also possible.

After cutting the strip 70 and if necessary. the edges 55, 56 of the container 50 according to the invention are presented here without a special spout according to FIG. 15. If the seams 60, 61 are now torn open and the contents of the chambers 57 to 59 are mixed, the can be cut open at any point mixed contents are removed from the container 50.

A comparable container 71 is shown in FIG. 16, in which the central, centrally arranged chamber 72 is provided with a spout 73 or closure of the type explained at the beginning, which is conventionally designed. A further variant of the spout 74 for a container 75 is shown in FIG. 17. The spout 74 has two lugs 76, 77 which on the one hand widen the radially outer chambers 78, 79 and on the other hand can be used, for example, to insert a straw or the like, when the inner seams 80.81 were torn open and the contents were mixed.

The containers 82 according to FIGS. 18 to 25 largely correspond to the exemplary embodiment according to FIG. 8. For receiving prefabricated containers 82 according to FIG. 18, a lateral edge 83 is formed clearly above the container 82. Since the container 82 here has three chambers 84, 85, 86, which are separated from one another by two seams 87, 88, three filling sections 89 to 91 have remained unsealed in the upper edge 83, cf. Fig. 19, through which the chambers 84 to 86 are filled.

The seams 87.88 run in the side view acc. 18 to 21 rounded off from the larger chamber 84.85 to the smaller chamber 85.86, which results in a funnel-like manner when the chambers 84.85 are compressed, the contents of which will move towards the smaller chamber, causing the seams Targeted load 87.88 until tearing.

In addition to the filling sections 89 to 91, further openings can be provided in the widened edge 83 for the reception of the containers 82, said openings being penetrated by support arms 92 to 97 and carrying the containers 82. By means of these support arms 92 to 97 or specially designed grippers 98 to 103, one or more of the containers 82 are received, compare FIG. 19, and become the by the support arms 92 to 97 or the grippers 98 to 103 Filling sections 89 to 91 widened by moving together according to FIG. 20. The support arms 92 to 97 or the grippers 98 to 103 can also be moved together in groups, for example in such a way that the two outer filling sections 89, 91 are first expanded to fill openings by moving the corresponding grippers 98, 99 and 102, 103 as indicated by the opposing groups of arrows, and then the grippers 98.99 and 102.103, which are moved together, are moved towards one another together with the inner pair of grippers 100, 101, whereby the middle filling section 90 is ultimately expanded to a filling opening according to FIG. 20.

After the chambers 84 to 86 have been inflated or expanded, the chambers are simultaneously filled from above, as shown in FIG.

Contrary to FIG. 20, FIG. 22 shows the grippers 92 to 97 being moved apart by arrows, so that the edge 83 is smooth and tensioned and, according to FIG. 23, sealing sections 148 to 150 of the filling sections can be sealed and / or glued.

According to FIGS. 24, the edge 83 is cut along the dash-dotted line and the cut strip 104 can be cut according to FIG. Fig. 25 are disposed of.

The filling of a further variant of a container 105 according to the invention is further explained with reference to FIGS. 26 to 38. The container 105 has four chambers 106 to 109, which are provided with four filling sections 112 to 115 for filling at the opposite edges 110, 111. The edges 110, 111 and in particular the arrangement of the filling sections 112, 113 and 114, 115 and Openings for support arms 116, 117 are rotationally symmetrical to a central axis that is perpendicular to the plane of the drawing.

According to FIG. 27, containers 105 are individually or in groups if necessary. first gripped by the gripper 118 at the upper edge 110 and, according to FIG. 28, by moving these grippers 118 together in the manner explained in the introduction, the filling sections 112, 113 are expanded to fill openings, so that after inflation and thus expansion of the chambers 107, 108 according to FIG. 29, these chambers 107, 108 can be filled is.

After smoothing and tensioning the upper edge 110 by moving the grippers 118 apart as shown in FIG. 30, these two filling sections 112 and 113 are sealed by sigil sections 151, 152.

In order to also fill the chambers 106, 109, the containers 105 are rotated about a vertical axis 120 in accordance with FIG. 32 and the flanges are expanded in accordance with FIGS. 33 to 35

Filling sections 114, 115 to the filling opening, the filling of the chambers 106, 109 and the smoothing of the edge 111 which is now at the top, so that, according to FIG. 36, sealing can be carried out by sealing sections 153, 154.

Trimming the edges 110, 111 along the dash-dotted lines in FIG. 37 ultimately yields a finished, filled container 121 and two edge strips 122, 123 as waste in accordance with. Fig.38.

Due to the symmetry properties of the edges 110 and 111 already mentioned, the distance between the support arms 116, 117 and the grippers 118, 119 for gripping the containers 105 basically remains the same, even if it is shifted on a line. The same applies to the travel paths for widening or tensioning and smoothing the edges 110 or 111.

A device is further schematically explained with reference to FIGS. 39 to 41, with which containers according to the invention can be accommodated and filling sections can be widened or smoothed again.

The device 125 for expanding or closing, for example, three filling sections has two clamping devices 127, 128 which can be moved in a guide 126.

Each clamping device 127, 128 in turn has two support arms 129, 130; 131, 132. The support arms 129-132, like the clamping devices 127, 128, can each be moved relative to one another and are suitable for carrying containers 133 according to the invention in openings made in edges 134.

The pairs of support arms 129, 130 and 131, 132 each enclose a filling section, while a third filling section is arranged between, in particular in the middle between, the two clamping devices 127, 128.

The support arms 129 to 132 have received a container 133, penetrating openings in the edge 134, for which purpose the support arms 129 to 132 can be moved perpendicular to their travel path for tensioning or widening, and are by counter-support arms 135 to 138 which can be moved in the same way , indicated by corresponding arrows, the free ends of the support arms 129 to 132 closed, the outer filling sections can be expanded by moving each of the support arms 129 and 130 or 131 and 132 of a clamping device 127 or 128 each of these filling sections. Preferably at the same time, in order not to overstretch the intermediate portion of the edge 134, the clamping devices 127, 128 themselves also move towards each other, so that a middle filling section is also widened, cf. Fig. 40.

The movements can be synchronized by mechanical gears, indicated by a toothed rack 139 and toothed wheels 140, 141 assigned to the tensioning devices 127, 128.

If the filling sections have been widened and the chambers of the containers 133 have been filled, the tensioning devices 127, 128 and in each case the support arms 129, 130 and 131, 132 are moved apart in accordance with FIG. 41 and the edge is smoothed and tensioned for sealing.

If containers are filled in an axial orientation, then a multiplicity of containers 142 according to FIG. 42 can be combined in one piece. The abutting edges 143, 144 can only be connected by film hinges, perforations or the like, so that it is very easy to separate containers 142.

FIG. 42 further shows that in this case

Embodiment connected to a spout 145, which can be integrally connected to the container 142, an edge 146 is further formed, which has a width such that a tool, e.g. a spoon or the like can be formed, for example, by embossing. This can also be provided for edges 143, 144.

Such a design of a tool can also in a single container according to the invention in one wide edge can be provided through which two half-shells are connected to each other.

In the container 155 according to FIG. 43, a bottle-like shape is again taken up, a seam 157 being provided at a narrowing point 156 in the region of a constriction, which separates a larger, lower chamber 158 from a smaller, upper chamber 159.

Due to the formation of the seam 157 tapering to the top, the larger chamber 158 is tapered like a funnel towards the smaller chamber 159. As a result of the measures mentioned, when the large chamber 158 is compressed, the pressure is built up in such a way that the seam 157 tears reliably.

A front 160 and a rear side of the container 155 are each formed by a multilayer, here three-layer, composite film 161, 162, cf. the unscaled section through the seam 157 in FIG. 44. The opposite layers 163, 164 bordering the interior of the container are made of a PE material with a peel component. If only these layers are welded and / or glued to one another, for example for the formation of the seam 157, then this welding or gluing can be separated again comparatively easily and in particular reproducibly. The force required for this, for example 2 N, 4 N or 8 N, can further be specified by the width of the bond or weld and / or by parameters such as the temperature and the duration of a weld. Since the layers 163, 164 of the PE material with the peel component are comparatively thin, a further carrier layer 165, 166 made of a PE material is also provided for the composite films 161, 162. These two layers 163,165 and 164,166 and if necessary. others are preferably manufactured as co-extrudates.

An outer layer 167, 168 made of a PET film is further laminated on. These layers 167, 168 can carry an imprint, for example, which is applied in a mirror-inverted manner on the back of the film, the sides adjacent to the layers 163 and 164, respectively.

Bordering a base 169, the front 160 and the rear of the container 155 are welded and / or glued to a peripheral edge 170 on three sides, cf. the unscaled section in Fig. 45.

At the edge 170, the outer PE layers 165, 166 are welded and / or glued to one another, a weld or adhesive seam that has a strength that largely corresponds to that of the composite film 161, 162 itself. Layers on the inside, at least the PE layers 163, 164 with peel material, are destroyed, so that there is no possibility of separating this weld seam or adhesive seam at the edge 170. This can be reinforced by knurling the edge 170.

The floor 169 is arched downward and the front 160 and the floor side still protrude from the floor 169 downward, so that there is sufficient stability.

In the exemplary embodiment of a container 180 according to FIG. 47, the two chambers 181, 182 are separated by two seam sections 183, 184 and a boat-shaped molded part 185, which with its side walls 186, 178 is glued and / or tearable against the front or rear side of the container 180, which is designed like a shell is welded. For this purpose, the molded part can be bonded or bonded according to the structure welding foils, be provided on the outside with a peel component.

In a plan view, the molded part 185 tapers to both ends like a ship's bow, similar to the design of the plastic ring 40, for example in FIG. 8, so that there is an easy transition from the seam sections 183, 184 to the molded part 185 and thus a simple, tight gluing or welding and thus separable separation of the chambers 181, 182 is made possible.

The boat-like molded part 185 is sealed, for example glued, penetrated by a tube 188, which is connected to a plastic ring 189 with a free mouth. As a result, a comparatively rigid core of the container 180 is formed, which significantly increases the buckling stiffness. This is further reinforced by the measure that the tube 188 has a section 196 protruding from the underside of the molded part 185. In particular, the free end of this section 196, as well as the edges of the molded part 185, are expediently rounded in such a way that the container walls cannot be injured or even pierced.

To the molded part 185, two stiffening elements 225, 226 are still connected, which, due to their elasticity when inserted into the container according to the invention, bear against the projecting section 196 of the tube 188 and, correctly positioned, space apart the film-like front and rear sides after spreading and give the container an overall increased stiffness.

For the connection of the tube 188 to the plastic ring 189, a web 190 extends over the cross section of the opening 191 of the chamber 181, cf. 48 and 49, the middle of the Opening 191 has a ring 192 for holding tube 188. As a result of this measure, the chamber 182 of the container 180 can, for example, first be filled through the tube and, after the tube 188 has been sealed, the chamber 181 through the cross-section of the opening 191 free from the web 190 and the sealed tube 188. Corresponding to the filling of the chamber 181, a mixed content is removed from the container 180. This measure has the advantage that the container 180 can be filled on conventional filling devices which are only adapted to the cross sections of the tube 188 or the opening 191. In order to be able to be held by a fork-like gripping device for filling, the container 180 still has a ring shoulder 194 that can be gripped under on a shaft 193 of the plastic ring 189.

The shaft 194 is further provided with a thread 195 so that the container 180 can be closed by a hood provided with an internal thread.

48 shows an arrangement of a plastic ring 197 with a tube 201 held in a ring 198 of a spoke-like web 199 in an opening 200 of a chamber, which further penetrates a boat-like molded part 202 and projects on the underside thereof with a section 203 which is in a second Chamber opens.

After the first chamber has been filled through the opening 200, this opening 200 is closed with an annular disk 204, which is only shown schematically, in particular sealed in an inaccessible manner by bouncing. The annular disc 204 is penetrated in the middle by an extension 205 of the tube 201, which clearly protrudes from an upper edge 206 of a shaft 207 of the plastic ring 197. After filling the next chamber through the tube 201, if necessary after sealing the opening 224 of the extension 205 in the manner of a guarantee closure, a hood 208 can still be screwed onto a thread 209 of the shaft 207.

Of course, the chambers can also be filled in the reverse order in largely conventional filling devices, for which purpose an annular shoulder 210 that can be gripped by a fork-like gripping device is also provided in this exemplary embodiment.

Once the seams separating the chambers have been torn off or the molded part 202 has been torn off the container walls and the contents have been mixed for enjoyment, this contents can be removed through the tube 201, as in the case of a conventional drinking bottle, by putting the protruding extension 205 into the mouth , In order to prevent a risk of injury there, the free end of the extension 205 is also provided with a bead 211.

In the exemplary embodiment according to FIG. 49, the upper extension 212 of a tube 213 is tightly closed with a sealing plate 214, preferably by bouncing, and a container content is poured out after ^" unscrewing a cap 215 through the opening 216 in the plastic ring 217.

This exemplary embodiment shows, on the section 219 of the tube 213 on the underside of a molded part 218, rib-like stiffening elements 220, 221, the area of which is oriented transversely to the longitudinal extension of the molded part 218, and which rest with their free edges 222, 223 on the container walls and thus stiffen them.
