DESCRIPTION:
BRIEF SUMMARY
The invention relates to a transport and storage container made of plastic.
A container of this kind is already known from CH-PS-537 842, in which access to the container is only possible by means of a one-piece slide when the latter is lifted vertically upwards either completely or partly. Access through the side opening is not possible when the containers are stacked on top of one another.
Furthermore, a container is known from DE-OS-29 09 136 in which access to the container is possible from the side even when the containers are stacked, but the flap itself comprises at least two parts which are hinge connected. The hinge connection and the locking mechanisms are expensive to construct with respect to their manufacture.
The objective of the invention is to design the opening flap in such a way that the flap is made in one piece and is easy to install and remove, so that the flap can also be operated when the containers are stacked, and the entire container, the flap, the connecting system between the container and the flap and the pivot and locking mechanism, is made from a single material and all the side walls together with the flaps located therein can be opened into the plane of the base plate.
The objective of the invention is achieved with transport and storage container with a base and side walls, in which at least one side wall forms a frame, in which closed at the top, for inserting a flap than can be pivoted off. The flap engages in bearing eyes of the frame side parts by means of coaxially arranged lower bearing pins projecting on both sides and which can be inserted by locking pins, projecting on both sides and arranged above the bearing pins, into mounting slots of the frame side parts which are accessible via insertion openings from an outer surface. The inside height of the frame of the flap-bearing side wall or face wall is greater than the flap height, and the slot height of the mounting slots is equal to or smaller in height than the height difference between the frame and flap. At least one of the mounting slots comprises a restriction as a detent for the corresponding locking pins, and the mounting slots forming the bearing eyes for the bearing pins are longitudinal slots. The surprising advantage is that it is still possible to open the flaps when the containers are stacked on top of one another and the flap itself is made in one piece, and thus does not have an expensive folding-door-like construction.
It is also an advantage that expensively formed hinge axes, which are expensive to construct with respect to their manufacture, are not necessary and despite this the pivot-opening function is maintained.
For a better understanding of the invention, the latter is explained in more detail with reference to the embodiments illustrated in the drawings, in which:
FIG. 1 shows a transport and storage container according to the invention viewed from above;
FIG. 2 shows the transport and storage container in cross section along the line II--II in FIG. 1 with the flap removed;
FIG. 3 shows the transport and storage container viewed according to arrow III in FIG. 1;
FIG. 4 shows a flap of the transport and storage container according to the invention in a front view;
FIG. 5 shows a view of a locking pin of the flap;
FIG. 6 shows the locking pin of the flap, in cross section along the line XI--XI in FIG. 5;
FIG. 7 shows a mount and a bearing pin of the flap in cross section along the line XII--XII in FIG. 3.
FIGS. 1 to 7 show a transport and storage container made of plastic for package freight with a rectangular base 1 and four walls. The base 1 is holohedrical or lattice-shaped and has reinforcement ribs 2 on its underside, the outside edge 3 of which is set back relative to the end walls, so that when the boxes are stacked it can be lowered into an open-topped box and lateral sliding can be prevented. The two side walls 4 are closed holohedrically or lattice-shaped and have oval grip openings 5. A face wall 6 is also closed holohedrically or lattice-shaped and also has a grip opening 5. At
