Abstract

The collapsible container comprises a lid (8), a baseplate (1) on blocks (2) and runners (3), and side sections (4-7) connected to the bottom plate by rectangular clamps (9). The clamps locate in second slots which on one side (11,15,16) are cut in the support blocks (2) in the region of the load bearing surface of the baseplate or lower down in the block itself, and on the other side (10) are cut in the upper side of the lid at a distance from the lid edge coinciding with the length of the clamp leg (9a). The clamps lie upon the lid edge by the angle section (13) where the two legs abut.

Description

Folding containers

This novelty refers to a container according to the preamble of claim 1. These containers are they use, for example, worldwide, to transport parts of cars between the different manufacturing plants and the like. These are generally containers whose bottom plate is configured as a pallet, whose side walls are made of wood plywood and side walls, bottom and lid join each other by means of steel clips. In the case of a drawer in parallelepiped shape are needed for mounting and closing by Usually two staples for each edge. That is, they are needed At least 24 staples. To completely disassemble a drawer you they return these staples to the place of origin along with the pieces stacked from the bottom, sides and top.

Disposable containers are known in which, for the return transport of the containers in folded state, the clips are fixed laterally to the stack formed by the lid, the side and bottom pins. To this end, some are milled grooves between the bottom studs, configured as a pallet and by the bottom face of the bottom, with the separation of the length of the arms of the staples that form a square. The two walls ends and the two side walls and the lid are stacked on others on the background. For this, the lid is placed with the face inside up so that the clip can fit into the groove peripheral milling. In this way the ends of the staples are free. The ends of the staples are folded outward in its front face, in order to facilitate its introduction in the grooves, both during container mounting and stapling the rows of plates of the disassembled container. The consequence of this is that this folded area of the clip attached to the row of plates can protrude up above the surface top of the lid. When stacking the containers on each other packaged by games there is therefore a danger that free ends and protruding from the staples are pushed towards outside and therefore they can let go and jump. This is also possible if they run during transport processes and storage. In addition, this variant of the stapling of the container per game only works if the six plate covers they are superimposed and all the plates have a uniform thickness very specific

Another variant of a collapsible container is known by US-A-5,535,909. In this case, the staples are applied to the folded container in such a way that protrude from the edge of the part of the container located more over.

This novelty aims to improve a container of this species in such a way as to prevent the Staples can jump when handling unarmed containers.

This objective is achieved in accordance with the claims.

The subclaims appear characterized preferred embodiments of the container object of the invention.

The following describes the novelty with greater detail by describing an embodiment example, referring to the attached figures.

Figure 1 shows a partial vertical section through the container object of the invention, in the area of fixing the staples, and

Figure 2 shows a front view of the area fixing the clips, leaving the two end walls of the container next to each other.

As depicted in Figures 1 and 2, on the bottom plate 1 are fixed some tacos that on its face Bottom are joined together by skates 3. This arrangement of the bottoms of the container as a pallet allows its handling with transport vehicles on the ground. In the unarmed container, side walls 4 to 7 are placed on the bottom plate 1, being able to have the side walls 6 and 7 and the extreme walls 4 and 5 different dimensions. Above the battery is placed in box 8. On the upper side of it goes milled a groove 10, at a distance from the side edge of the lid 14, equivalent to the length of the arm 9a of the clip 9. A second slot 11 is milled in the area where the bottom plate 1 rests on block 2. This place is chosen in such a way that the clips 9 fit there with their other end of attachment, is say, that the distance between the upper side wall of the slot 11 and the upper side edge of the lid 8 corresponds with the length of the arm 9b of the clip 9.

There is also the possibility that not all lateral parts 4, 5, 6, 7 become superimposed below the cover plate 8 and on the bottom plate 1. This happens when the dimensions of the container are such that, for example, two side walls can be placed next to each other. This reduces the height of the stack since the number of layers of Side walls are reduced by one unit. Therefore it is not it is necessary to arrange slot 11 in the bottom seating area on the blocks but in the same block 2. If they can be positioned next to each other two of the four side walls, you have to mill groove 11 below, at a plate height, so that then get slot 15. If it is possible that in addition to the two Side walls 6, 7 can also be placed next to each other the two extreme walls 4, 5, the height of the stack is reduced by two plate heights, so it is necessary to place the groove more below, in two plate heights, as shown in the groove 16. In addition, the possibility of using plates different thickness In this case, slot positioning milled in block 2 depends on the total thickness of a stack of plates of a container set. This way you get a greater variability and stability with respect to the solution current.

In this mode of fixing the clip 9, the extreme edges of the fastener fixing areas penetrate deep in slots 10, 11 or 15, 16. On the upper face of the cover 12 rests only the arm 9a and the corner 13 of the angle 9 tightly embraces the upper side edge 14 of the cover 8. With this smooth surface of the staple arrangement it is impossible that the clip is hooked with pieces that slide over the face top of the cover 12, such as the skates of the unarmed container that is stacked on top. In this way neither can the staples jump.

Depending on the size of the container, the bottom of the Container has at least four tacos. Usually for each container edge two staples 9 are needed, so that in Return transport, staples can be accommodated in the form described above

The new arrangement of the staples in the unarmed container supposes a great progress with respect to the conventional provision, since the risk of losing the staples when handling unarmed containers, also during transport.

The novelty is not limited to the embodiment described above, but covers all variants covered by The claims.
