Description

Container {CONTAINER}

The present invention has a vessel wall, a vessel bottom, and a vessel opening, the vessel wall extending substantially conically from the bottom to the opening, the inner side of the vessel wall having laminated ribs distributed around the circumference and axially directed. It's about courage.

The purpose of the stacking ribs located inside the container wall is that, when stacking a plurality of containers against each other, each upper container is supported in each lower container, so that the two conical container walls are in contact with each other. It is to avoid sticking against. Being supported by the stacking ribs, there is a small clearance between the two container walls, which prevents the stacked containers from being easily separated from each other. The vessels supported by the laminated ribs are placed inside each other in such a way that the peripheral area of the vessel opening of each upper vessel is located outside the vessel opening of each lower vessel, with the device for securing the transport belt. Is placed.

Instability of the position of the containers supported by the stacking ribs can occur when handling or transporting containers adapted to each other as above.

It is an object of the present invention to provide a container which is of the kind mentioned in the introduction of the description, which can improve the stability of the position of the containers stacked on one another.

According to the invention, in a container of the kind mentioned in the introduction of the description, in the radially outer area outside of the bottom of the container, at least one of the containers located underneath the container when the plurality of containers are stacked with respect to each other At least one recess is formed that can engage one lamination rib to allow the containers to be secured in such a way that they do not rotate relative to each other.

According to this structure, when stacking a plurality of containers of this kind, each upper container is held by the stacking ribs of each lower container in a non-rotating manner. Furthermore, containers stacked on one another can be placed and held in a position set relative to one another.

At least one of the lamination ribs may have a greater axial height from the bottom of the vessel than the remaining lamination ribs. For the remaining laminated ribs the difference in height corresponds at least to the depth of the groove formed on the outside of the bottom of the container.

In one preferred embodiment of the invention, the radially outer area outside of the bottom of the container protrudes in the axial direction and reveals a substantially continuous foot. The backing portion exposes at least one interruption forming at least one groove in the bottom of the container.

At least one stop formed in the continuous support portion underneath the bottom of the container makes it particularly easy to produce a groove formed in the bottom of the container for engagement of the at least one laminated rib.

However, the groove may also be suitably formed portions of the peripheral region of the bottom of the container which are open downwards and further preferably also radially outward. Similarly, webs or protrusions may be formed at the bottom of the vessel, and one or more tops of the laminated ribs, i.e., the ends facing the vessel opening, may be maintained in a manner that prevents rotation about the vessel axis between the web or the protrusions. Can be retained.

The width of the groove along the circumferential direction of the bottom of the container is slightly larger than the width of the laminated rib along the circumferential direction of the container wall, so that the clearance (gap) set between the upper end of the laminated rib and the wall of the groove is maintained.

On the other hand, the width of the groove portion may be slightly smaller than the width of the laminated rib, so that a clamping effect set between the upper end portion of the laminated rib and the wall area of the groove portion may be obtained. In this case, the containers stacked on each other can be separated from each other only if they overcome the forces by the set clamping.

For example, the laminated ribs located inside the container wall injection molded in the injection mold can be integrally molded to the container wall and have a geometry suitable for shaping the container and removing it from the mold. Laminated ribs preferably extend from the bottom of the container.

The height of the stacking ribs, or the length of the stacking ribs from the bottom of the container, is appropriately dimensioned in such a way that the container walls of the stacked containers with respect to each other are not jammed. There is a small clearance between the container walls, which allows the containers stacked on one another to be aligned with each other in the set direction. Due to the arrangement of the stacked ribs and the grooves formed in the bottom of the container interacting with the stacked ribs, the required direction of the containers stacked on each other can be limited, and in the non-rotating engagement of the stacked ribs with respect to the grooves By this, the above direction can be maintained during operation or transport on the containers.

On the other hand, the laminated ribs may have the same length, and in this relationship, a plurality of grooves are formed on the outside of the bottom of the container to engage the laminated ribs of the container located at the lower side when the plurality of containers are stacked on each other. . Here, at least one of the grooves allows the containers to be fixed non-rotationally with respect to one another since at least one lamination rib engages the groove.

In particular, grooves distributed along the circumferential direction may be formed outside the bottom of the container to correspond to the laminated ribs, and in each case the grooves will engage the laminated ribs of the lower container, so that the containers do not rotate about the container axis. In place in such a way that it can be fixed in place.

In order to ensure sufficient stability when supporting many containers stacked with respect to each other, and to resist the rotation of these containers relative to each other, the laminated ribs are one to three times the wall thickness of the container of that part. Corresponds to the range and forms radially extending from the vessel wall. The radial extension preferably corresponds to one to two times the thickness of the edge of the container.

The vessel outer wall preferably does not have a continuous flange. The container outer wall is preferably substantially smooth and (or / or) free of protrusions (and / or) except for a radially outwardly-projecting holding area for the carrying strip and a corresponding area for connecting to the container wall. ) Is formed such that an undercut is not formed.
