DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

The invention concerns a two-part case of plastic or a similar material for accommodating beverage bottles with means of mutually securing and locking the identical components that compose the case.
European Patent 0 048 006 discloses such a case. Its end user can disassemble it into its components, especially to facilitate return to the supplier, who can then reassemble it for storing and shipping the product. Each component has a hook that is inserted into another component, and there are slides that operate in conjunction with the hooks. This design is very complicated.


SUMMARY OF THE INVENTION

The object of the present invention is accordingly, with the known state of the art as a point of departure, a generic case that is easy and simple to assemble and to disassemble into its components and cost-effective to manufacture.
The object is attained in a generic case in accordance with the invention in that vertical assembly strips are mounted on each component adjacent to its interface, interlock with each other and engage the components while the case is assembled, and can be separated by sliding them to each side and in that bolts are provided that can prevent the components from sliding to each side.
The assembly strips, which are integrated into the components, and the bolts, which secure the assembled components together are sturdy enough to be easy to manufacture. The assembled case is disassembled by raising the bolts that prevent the components from sliding to each side and sliding the components along the interface to disestablish the joint. The components can then be carried around individually, one in each hand of whoever is carrying them for example. The reverse sequence--positioning the components together and bolting them into position to create the assembled case--will result in an article that can be stacked and delivered from the bottling plant to the point of sale and vice versa.
The assembly strips can be sunk into the ends of the components that accommodate the bolts in the transitional areas of the interface. The assembly strips in one preferred embodiment are mutually interlocking claws in cross-section, with one claw bent back from the end, recessed into the interface,.and accessible from outside and the other claw in the same plane as the end, projecting out beyond the interface, and accessible from inside. The claws in one embodiment have jaws that taper toward the bottom and noses that accordingly taper toward the free face.
Another version of this embodiment features, preferably in the vicinity of the assembly strips, both a return that is accessible perpendicular to the interface and a mount that extends into the return and projects beyond the interface, whereby the recess interlocks with the mount and prevents the components from sliding up and down in relation to each other.
The simplest approach to locking into position the components assembled into a case are slides that travel out of the components and beyond the interface into a return on the same plane in the adjacent component. One embodiment has carrying straps that pivot on the ends of the components and is characterized in that at last one leg of each strap has a projection that extends beyond its point of articulation with its free end extending through the assembly strip that is in front when the strap is pivoted against the component and engages the matching recess in the other component. When the projection is in the shape of a Z, the locking structures can to advantage be remote from the upper edge of the case. The carrying straps, which lock the assembled components into a position pivoted against each other while the case is assembled and provide a grip for carrying the disassembled case around when pivoted up and away from the components to disestablish the lock, constitute an ideal locking mechanism while simultaneously making the components easier to handle. The two legs of the strap in one version of this embodiment can have projections that extend beyond their point of arti
