Plastic bottle containers

The invention relates to a bottle container made of plastic, in which at least the upright side walls are provided with edges at their upper ends and its interior in compartments for the purpose of receiving the bottles is divided.

Containers for bottles containing beverages are known, the upright walls of which are provided with protruding edges at their upper ends or in the vicinity _{thereof o} viegen these protruding edges, however, one sees oneself forced at or near the point at which they are in the ground of the container pass over to provide the walls with protruding edges, since in order to obtain a perfect mutual bond these containers when they are arranged on pallets both at the upper and at the lower end of the crosswinds completely against each other -! η ··.

Such at the lined ends of the> u real standing walls lower rims attached near the bottom of the bottle container however, cause all sorts of difficulties in practice. So it often happens that the foregoing Un-Ierrand hooks under the bottom of a container, making the proper arrangement of the container vsrh: / idcet.

Another mar-ute '^; l is dal? by the presenceir ■ * - '■■? protruding edges at the upper and lower ends of the upright walls, the circumference of the bottle container is larger than the actual container without a rim. This is particularly difficult when placing it on normal pallets and one sees oneself forced to make arrangements "

Another disadvantage is that for space-saving reasons, the upper and lower edges as possible be chosen small so that as little seam as possible is lost between two bottle containers lying opposite one another goes.

The object of the invention is to create bottle containers of the above type that are not burdened with these defects and, in particular at the upper end, a very wide edge is to be ^{created for capturing such ..ehäli 1} without this increasing the size of the means the ic.lumes taken from the well-known ice containers,

The object set is achieved according to the invention by that at least two opposing upright side walls converging in their upper part are arranged to each other.

The converging arrangement of two opposing walls achieves that without any further increase - in other words, space requirements - the circumference of the container has a very wide upper edge attached to capture these containers can be.

Advantageously, the walls converge in twos = in pairs at the same angle, with the one against the other subsequent container walls merge into one another via a corner transition part which is at least substantially perpendicular to the floor.

In this way it is achieved that the demolding of a Such a container is easier to do than in the case that all container walls including the corner transition parts converge inward. When all sides converge including those near the corners Such a plastic container can be removed from the mold with difficulty.

209850/0687

By applying the standing perpendicular to the ground Transition parts, these disadvantages are partially eliminated.

Advantageously, mutually adjoining converging parts of the container side walls go over one Transition part which diverges with respect to the plane perpendicular to the ground in the vicinity of this corner transition part, into each other.

The diverging arrangement of the transition parts makes it much easier to remove the bottle container from the mold.

Converging arrangement is expedient the side walls of the container and the divergent arrangement of the corner transition parts between two on top of each other following side walls chosen so that the total circumference of the bottle container in a parallel to the floor Level is always constant over the total height of the container.

Of course, it is also possible to choose the circumference somewhat larger in the part where the side walls converge; however, this offers no advantages because it will increase the size of the container on the outside.

209850/0687

Ks is particularly recommended that the transition of the upright standing winds from the position perpendicular to the ground to a converging position in the upper half and preferably the upper third part of the upright side wall takes place, as there are no bottle bellies here.

Further advantageous and expedient features of the invention to be protected also emerge from the following Embodiments as described and / or shown; these individual features are - just like those already aforementioned features - also together (in combination) essential to the invention.

Pig. 4 shows a sketch, the transition line of converging wall parts through a diverging one Transitional part is shown.

In the drawing is one with a testicle 2 and upright standing walls 3 to 6 provided bottle container 1 made of plastic shown.

The 3oden 2 of the container made of plastic consists of a any construction of rib-shaped parts 2a, 2b, 2c.

These rib-shaped parts 2a, 2b, 2c or the walls 3 up to 6 also carry longitudinal partitions 7 and transverse partitions b, so that compartments 9 arise for receiving the bottles.

The lower parts 3a, 4a, 5a and 6a of the opposite perpendicular side walls 4 and 6 or 3 and 5 of the container 1 connected to the base 7 are perpendicular to this base 2. From about 2/3 the height of the upright side walls of the container, the upper parts 3b, 4b, 5b and Gb of the side walls converge in an upward direction T di enes.

209850/0687 BAD ORIGINAL

The length of the peripheral edges 10a, 11a, 12a and 13a of the Bottle containers 1 are chosen so that they end differently approximately in the direction of the vertical of the container bottom, so not, at most hardly survive. They may extend from the respective peripheral edge na to 13a as stiffening ribs 15 inwards.

Due to the converging arrangement of the upper parts 3b, 4b, 5b, 6 and 6b of the side wall parts, the demolding of a such a container cause difficulties in the production or at least be less easy to implement ", Although it is possible in practice to demold such a container while it is still warm and then through rapid cooling to ensure that it retains the desired shape, it is indicated in the corner points corner transition parts lying between successive side walls 3, 4, 5 and 6, at least vertically to be attached to the ground and preferably diverging. These Transition parts are denoted by 14b.

The divergence of the transition parts 14 and the convergence of the upper parts 3b, 4b, 5b and 6b of the side walls are chosen such that the circumference is almost always constant in a plane parallel to the ground. This scope can also be slightly larger, but in this case the transition parts should diverge outwards «

2 0 9 8 5 0/0687

On the other hand, the height of the converging part of the container side walls 3b, 4b, 5b and 6b should not be too high be chosen because of difficulties in demolding prepared, but on the other hand also not be too small, because in this case the twisting of the wall at their transition into the corner transition parts 14b could be too strong. In any case, the transition is in the upper half the side walls of the container and preferably in the upper third part, where - when the container is filled is - no bottle belly is located.

Finally, it is indicated (see FIG. 4) to choose the radius of curvature R of the lower part 14a of the corner transition part as large as possible. This can also be easily achieved because the outer side of the corners of the compartments 9a, 9b and 9c, 9d serving to hold the bottles can be slightly rounded without significant loss of space in the compartments involved. On the other hand, it is advisable to use the radius of curvature R _? to be selected as small as possible in the diverging upper part 14b of the corner transition part 14. This can also be done without hesitation, because only the bottle necks are located in this area.

209850/0687

By using a small radius of curvature R becomes at a certain divergence in the diverging part 14b, a maximum draft angle is obtained, which is a faster compensation of the anti-deformation angle (because of the converging parts of the side walls of the container) the demolding has the consequence.

To maintain easy demolding, it is provided that that the length of the line part ABCD, i.e. the width of the corner transition part 14a, of the undeformed lower Parts of two adjacent container side walls connect or the transition line between converging and non-converging parts of the container side walls to the width of the corner transition part 14b between two adjacent converging parts 4b and 5b of the container side walls 4 and 5 defining line part EFG is the same.

It is clear that wide detection margins limited by the line AKD are available, so that with almost the same the normal bottom surface, a wide detection rim container can be obtained without doing so is associated with an increase in the space occupied by the container. The transition capture walls are designated by 15. The length and width of the floor are almost as great as the greatest distances in length and width of the generatrix of the upper surface

of the container. The edges at the top of the side walls almost form a rectangle.
