Abstract

A plastic bottle-type container has at least two adjacent chambers, each having a bottom part, the adjacent chambers being separated by seams which can be at least discontinuously broken.

Description

Bottle-like container

BesehreÜbung:

The invention relates to a bottle-like container made of a plastic.

PCT / DE03 / 00457 proposes a bottle or bag-like container made of plastic, in which at least one chamber is separated from a second chamber, in particular by a tearable seam. Such a container is preferably used for the separate storage of two components, in particular that of a food, for example a baby food, which are to be mixed for consumption. Such mixing takes place in a simple manner after tearing open the tearable seams separating the chambers by milling or kneading the container.

A bag-like design of the container according to PCT / DE03 / 00457 is not a problem. In the bottle-like design of a container there, however, the stability is impaired by chambers which bend at a seam and there become further, constructive

Measures proposed by which the stability can be increased. In addition, the buckling stiffness is often not sufficient, particularly in the case of comparatively high containers, for example with chambers lying one above the other. For this reason, it is further proposed there to insert an essentially centrally extending tube into the container, by means of which the buckling rigidity and also the stability are increased.

Against the background of this technical problem, the invention makes it its task to provide a bottle-like container made of a plastic, which at simple geometry and with a simple structural design already has sufficient stability and rigidity.

To solve this technical problem in a bottle-like container made of plastic according to claim 1, it is ensured that at least two adjacent chambers are provided, each with a base part, and that a third chamber preferably tears open the two adjacent chambers at least in sections Seams separate.

The two chambers arranged side by side, each with a base part, give the bottle-like container according to the invention great stability and a pleasing appearance, since no chamber can bend at the seams, for example. The mixing of the contents of the preferably three chambers is also simplified since comparatively long, tearable seams are provided over a maximum cross section, so that the components can be mixed without the components

Cross-sectional narrowing must happen.

It has proven to be expedient to design the bottom parts in a top oval shape and to arrange them with the tips facing one another, in particular also at the tips, whereby the bottom parts can preferably be formed by a one-piece bottom. As a result of these measures, a simple, non-tearable welding of a one-piece front and a back to the bottom parts made of a plastic is made possible in a simple manner, with a knot being formed by the abutting tips, in which edge-side, non-tearable seams of Container with inner, tearable seams meet.

It can be provided that the third chamber completely separates the two chambers arranged side by side. Then there are only two tearable seams or two tearable seam sections are provided, by which the three chambers are separated from one another in a tearable manner. In a first alternative, the third chamber can also be provided with an inserted bottom part, which is likewise again of oval shape and which can be formed in one piece with the bottom parts of the chambers arranged next to one another. As a result of this measure, the third chamber can also be formed in a comparatively large volume.

It has proven to be expedient to provide the third chamber in particular with a re-closable spout, a tear-off or cut-off pouring flap or the like for removing the finished mixed product.

If a small volume is only necessary for the third chamber, the third chamber can be formed in a tip tapering towards the bottom parts of the adjacent chambers.

In a further design, this tip and the tips of the base parts of the adjacent chambers facing one another can then run out in a knot or the tip of the third chamber can continue in a further seam, this additional seam likewise separating the chambers arranged next to one another in a tearable manner and again in particular in a knot with the points de.tr facing each other meets the two bottom parts of the neighboring chambers. In a side view, the tearable seams will then be approximately Y-shaped.

In a further variant of the bottle-like container according to the invention it is provided that the tip of the third chamber meets with a tip of a fourth chamber. If the fourth chamber also has an especially pointed oval bottom part, the third and fourth chambers can be diabolo-like. The filling and emptying of the container according to the invention can be simplified by the measure that chambers lying directly next to one another at the top, on a side opposite the base parts, are each closed by a boat-like section of a molded part in a plan view, which therefore essentially also the floor plan of the base parts resume, but the boat-like sections are regularly made smaller. These shuttle-like sections can be provided with suitable openings for the filling or can only hold the individual chambers open, and such openings are sealed after the filling of the chambers or used as a spout.

The container according to the invention is expediently formed symmetrically to a central plane. The manufacture and filling of a symmetrical container are comparatively simple compared to complex structures that are possible, since, for example, distances to the central plane are of the same design.

To increase the stability, a container can be designed such that at least one chamber is closed by a base part, that the base part has a filling opening, and that the base part is seated on a base.

The design of a pedestal, which according to the task will be provided with a sufficient footprint and weight, ensures a high level of stability. This is particularly the case when all of the chambers have base parts which are seated on a common base which, in a preferred embodiment, has a base plate which extends freely at least in sections.

In addition, with such an arrangement of the bottom parts, the individual chambers are filled through the filling openings of the bottom parts from one direction, from the bottom side. For this purpose it can be expediently provided that a filling opening extends through the base, in particular all filling openings. Such filling openings are closed after the chambers have been filled, for example by beating or the like.

The base parts and the base can be formed by individual molded parts that are glued or welded together, for example. Alternatively, the base parts and the one or more feet can also be formed in one piece, which can save manufacturing costs.

In a constructive embodiment it is further provided that a cylindrical shaft is arranged between a base and a base part. Such a shaft is easy to grasp and hold, for example, for filling by a pincer-type gripping device.

It has also proven to be expedient if the shaft has a cross section that is recessed relative to the associated base part, with which it can be recognized for a gripping device, for example, as a holding section.

For this purpose, the shaft is inevitably free of a plastic film delimiting a chamber.

In a further embodiment of the invention it is provided that the base parts are arranged in a row. Sitting on a common base in the form of a base plate, for example, can then be elongated oval.

In a further embodiment variant it is provided that the base parts are circumferentially spaced from one another and are therefore formed independently of one another.

In a further embodiment, it can be provided that the bottom parts are designed in a gore-like manner in a plan view are, in particular assign to each other tapered tapered tips of adjacent floor parts. As a result of this design, it is possible to bring together two foils delimiting the chamber (s) at the front and back and to arrange the tearable seams there butting against an external, non-tearable seam.

It can further be provided that adjacent tips of the bottom parts that run out in a gusset manner are connected to one another. By welding through, for example, a secure, liquid-tight gluing and / or welding is thus also made possible in the nodes of the seams that meet.

If the base parts are separated radially from one another, an additional web can connect the base parts to one another and on the one hand further increase the stability and on the other hand be provided with an adapter for a gripping device for filling.

In a further embodiment of the container, three chambers are provided, the chambers being triangular in a side view, a central chamber having a tip oriented towards the base and closed by a base part, and the two neighboring ones

Chambers are formed with tips oriented away from the base and abutting the middle chamber.

In particular in such an embodiment of the container, the middle chamber has a comparatively large upper longitudinal extent, which is why the middle chamber preferably has an insert on the side opposite the bottom part, which is designed as a pourer. Such a pourer can also preferably be configured in a plan view in a gusset manner.

Alternatively, a filling opening can also be used to remove the contents of the container. Doing so preferred that between the at least two base parts and a base plate, the filling openings is provided except for a closing intermediate piece.

A base plate of the pedestal can then be designed as a closure of a bore connecting a spout to the filling opening of a base part that remains open.

In the embodiment of a bottle-like container 1 according to the invention shown in FIG. 1, two chambers 2, 3 arranged next to one another are each provided with a base part 4, 5, which results in a large, stable standing surface for the container 1. A third chamber 6 with a bottom part 7 also separates the chambers 2, 3 with tearable seams 9, 10. Tear the seams 9, 10, for example, by walking or pressing the container

1, the contents of the three chambers 2, 3, 6 will mix with one another and the mixed contents can be removed from the container 1 by a spout 8 which can be closed again, for example, in the third chamber 6 separating the two chambers 2, 3 arranged next to one another.

At the top, the three adjacent chambers 2, 3, 6 are each closed by a boat-like section 9-11 of a molded plastic part. The reclosable spout 8 can then also be formed in a simple manner. In addition, the boat-like sections 9-11 can be provided with openings for filling the three chambers 2, 3, 6, which are closed after filling - except for the spout 8.

Comparable to the boat-like sections 9-11, the bottom parts 4, 5, 7 are of pointed oval design and the tips of the bottom parts are facing one another and are arranged in contact with one another in nodes 16, 17.

The bottom parts 4,5,7 are formed by a one-piece bottom. As a result of the measures explained, the non-tearable seam 14 then falls between one foil-like front part 15 and the bottom parts 4, 5, 7 with the tearable seams 9, 10 as it were in each of the nodes 16, 17 together. The same applies on the upper side of the container 1 between a non-tearable seam 18 between the front part 15 and the boat-like sections 11-13 in nodes 19, 20.

The same applies to the rear of the container 1 according to the invention.

In the exemplary embodiment of a container 24 according to FIG. 2, the adjacent chambers 25, 26 are separated by the tearable seams 27, 28 of a third chamber 29 designed in a gusset-like manner. The chamber 29 also has a molded part 30 of a boat-like design with a spout 31 which can be closed by a cap.

The bottom parts 32, 33 of the chambers 25, 26 are again formed oval-shaped and arranged with the tips 34, 35 facing one another. In addition to these two tips 34, 35, a tip 36 is formed from the seams 27, 28 of the chamber 29, so that the non-tearable seam 38 between a front part 39 and the bottom parts 32, 33 and the seams 28, 29, as it were, in one Discontinue node 37.

In the exemplary embodiment according to FIG. 3, too, a third chamber 42 arranged between two adjacent chambers 40, 41 has a tip 43 which points to the tips 44, 45 of the pointed oval base parts 46, 47 of the chambers 40, 41 facing one another. In the exemplary embodiment according to FIG. 3, however, the tip 43 continues in a further tearable seam 48 which, as far as the tips 44, 45, separates the chambers 40, 41 in a tearable manner.

The chamber 42 is not a boat-like molded part with a spout. Rather, a seam 49 that continuously closes the chamber 40, 41, 42 on the upper side and cannot be torn is provided, which over the chamber 42 in the manner of a flap 50 for a The opening is designed to be able to be torn open or torn off, indicated by a tearing line 51. It goes without saying that the force for tearing open the tab 50 on the tearing line 51 is greater than the force for tearing the seams separating the chambers 40-42 48,52,53.

In the exemplary embodiment of the container 60 according to FIG. 4, the chamber 61 again runs out in a tip 68 and separates the chambers 64, 65 with inserted bottom parts 66, 67 with tearable seams 62, 63.

Opposite the chamber 61 is a fourth chamber 69 with a bottom part 70, the tip of which coincides with the tip 68 of the chamber 61, so that in connection with the boat-like molded part 71, which closes the chamber 61 on the upper side, the two chambers 61 , 69 with the tearable seams 62, 63 and 72, 73 in a diabolo shape. In this container 60 as well, the base parts 66, 67, 70 can be formed by a common, one-piece base.

The exemplary embodiments of containers according to FIGS. 1-4 are symmetrical to a central plane. The exemplary embodiment of a container 80 according to FIG. 5 does not have such symmetry properties.

In the case of the container 80, two adjacent chambers 81, 82 are separated from a third chamber 83 by seams 85, 86 which run out in a point 84, the point 84 continuing in a further seam 87 and the jointly with the points of the two base parts facing one another 88.89 of the chambers 81, 82 runs out in a knot.

The chamber 81 is separated from another chamber 90 by a tearable stitch 92. The chamber 90 also has a base part 91 which is formed by an integral base with the further base parts 88, 89. A chamber 94 which is separated from the chamber 82 by a further tearable seam 93 is formed without a bottom part. The chamber 94 as well as the chambers 81, 82, 83 are closed on the upper side by boat-like sections 95-97, the middle section 96, which closes the chamber 83, again being provided with a reclosable spout 98.

The container 101 shown in FIGS. 6 and 7 has three adjacent chambers 102, 103, 104, which are separated from one another by tearable seams 105, 106.

If the container 101 is loaded, for example by pressing or flexing, the seams 105, 106 tear open and the contents of the chambers 102, 103, 104 can be mixed with one another. The chambers 102, 103, 104 are delimited by a front and a rear plastic film, which are connected at the edge by an essentially circumferential seam 107, the tensile strength of which is significantly higher than that of the tearable seams 105, 106, so that there is no danger of the container 101 being loaded this seam 107 tears open.

On the bottom side, the three chambers 102-104 are each closed by a bottom part 108-110, each bottom part 108-110 having a filling opening 111-113 for filling the respective chamber 102-104.

The base parts 108-110, which are circumferentially separated here by way of example, are seated in a row on a common base 114 which, as a base plate 121 here, is elongate oval and of a corresponding size gives the container 101 great stability.

Since in the exemplary embodiment the base parts 108-110 and the base 114 are formed in one piece, the filling openings 111-113 also penetrate the base plate 121 and can be closed, for example by beating, after the chambers 102-104 have been filled. Alternatively, if the base parts and the base are each designed separately, the filling openings of the base parts can also be closed by a continuous base plate 121 after the chambers 102-104 have been filled.

Between the base 114 and the base parts 108-110 there is a cylindrical shaft 115-117, which is cylindrical in cross section and which has a recessed cross section compared to the associated base part 108-110. Such shafts 115-117 can be gripped by fork-like or pincer-shaped gripping devices and hold the container 101 for filling. For this purpose, each shaft 115-117 is expediently free of a film delimiting the chambers 102-104.

In a plan view, the bottom parts 108-110 are designed like ships or gussets, thus tapering in two opposite tips. The tips of two adjacent base parts can be connected to one another or separated from one another as in the exemplary embodiment. As a result, the foils delimiting the chambers 102 to 104 can be welded directly to one another here via the free space between two adjacent tips.

7, it can be seen that in the exemplary embodiment the three chambers 102-104 are essentially triangular in shape. The middle chamber 103 has a tip oriented towards the base 114, which is closed by the base part 109. The two outer chambers 102, 104 adjacent to the middle chamber 103 are also approximately triangular in shape, the tips of which are each formed above the base 114, but bear against the middle chamber 103 via the seams 105, 106 or the seam 107.

At the top, the triangular-shaped, middle chamber 103 has a comparatively long side. The seams 107 there, which form the chamber 103 Front and rear foils there enclose an insert 118 which, in a top view, again ends in a gusset or boat-like shape and ends in two opposite tips and which is further designed as a pourer 119 with, for example, a cut-off tip 120.

Another exemplary embodiment of a container 122 is explained in more detail with reference to FIGS. 8-13.

The container 122 has, for example, two chambers 124, 125 separated by a tearable seam 123. Two base parts 126, 127, cf. also FIG. 4, with filling openings 128, 129 close the chambers 124, 125 on the underside.

The bottom parts 126, 127, again designed as gussets, are connected to one another by a web 130, which is connected to round shafts 131, 132, which have a reduced cross-section.

The web 130 lies below a film 133 delimiting the chambers 124, 125, which is connected to the bottom parts 126, 127 by a seam 134 that cannot be separated. The web 130 is thus freely accessible. As a result, adapters 135 can be provided on the web 130 here in the form of recesses with a square cross section for a gripping device, which act on the adapters 135 of the web 130 for filling the chambers 124 and 125, hold the container 122 and thus fill through the Allow filling openings 128 and 129 by machine.

The two chambers 124, 125 with the bottom parts 126, 127 formed separately from one another, connected via the web 130, are held by a base 136. The base 136 is formed in two parts with a base plate 137 and an intermediate piece 138. The intermediate piece 138 has two receiving bores 139, 140 for a liquid-tight receiving of the shafts 131, 132 of the base parts 126, 127. The Bore 139 is designed as a blind bore so that the filling opening 128 can be closed.

In contrast, the receiving bore 140 connects the filling opening 129 of the base part 127 with a spout 141, cf. 12, so that, for example, liquids mixed in the chambers 124, 125 can be removed as a mixture again from the chambers 124, 125.

The bottom plate 137 serves as a closure of the spout 141, which for this purpose has a central sealing receptacle or a plug 142 for the spout 141.
