Lockable shipping container

The present invention relates to a lockable shipping container with a bottom Jacket, on the upper edge of which a dust- and liquid-tight closing lid is arranged.

The known lockable shipping containers of this type, which are especially used for the transport of liquids and Sehüttgiltern are generally in three parts and accordingly consist of a floor on

pointing coat, a lid and a peripheral hoop used to secure the lid Eccentric lock. These three-part containers, which usually have a circular cross-section, require a relatively large amount of work and material the production, also have an unfavorable use of space on the standardized pallets and are also also not automatically lockable.

These disadvantages are to be eliminated thanks to the present invention in that both the upper section of the casing adjacent to the lid and that from the upper casing edge into the interior of the container protruding lids each have a bead running around the entire circumference, their position and dimensions are chosen so that they lie on top of one another in the closed state of the container and their main purpose consists in pulling the cover down when it is placed on the jacket and thereby applying elastic pressure to achieve a seal arranged between the cover and the upper casing edge.

When the container is closed, the two beads mentioned can either go into the inside of the container or after be directed outside.

The upper edge of the container jacket] s ipt

expediently with the formation of an edge bead rolled up on the outside so that the lid overlaps this bead.

The edge of the lid preferably has at least two securing tabs which are closed in the Place the condition of the container against the underside of the beaded edge.

The connection points between the securing tabs and the edge of the lid have a special Embodiment has a weakened with respect to the cover and the tabs cross section.

Exemplary embodiments of the subject matter of the invention are illustrated in the accompanying drawing.

Figure 1 is a side view of one with shipping containers loaded pallet,

Fig. 2 is a plan view of the pallet according to FIG. 1 and the

3 to 5 are partial sections of the upper edge area various embodiments of shipping containers.

1 and 2 show in simplified form a pallet 1 which corresponds to type I and accordingly has a width of 800 mm and a length of 1200 mm. There are a number of partially avalanche on the pallet Lockable shipping containers stacked on top of one another

509809/0376

2. These containers have a rectangular cross-section with the dimensions 300 χ 4θΟ mm, so that eight containers can be placed on the pallet surface with the best possible use of space. A similarly favorable arrangement would result if the containers shown were also used with other pallets, for example type II or

III with the dimensions 1000 χ 1200 or 1200 χ 1200 mm. A first embodiment of the container is shown in FIG. 3, in which the container is again in its entirety is denoted by 1. This container has a jacket 3 of rectangular cross-section, which with a bottom, not shown, is provided. The container

but could also have a square or round cross-section. The lower container part is for the present invention is of no importance and has therefore not been shown.

The upper edge region of the container jacket is bent over to the outside, forming an edge bead 4 and also has just below the edge bead 4 an outwardly directed one running around the entire circumference of the jacket Retaining bead 5. In the selected embodiment, the retaining bead 5 has on each container wall Shape of a cylinder section, but could also be done in another way, see B. with an approximately triangular cross-section, be trained.

A cover designated in its entirety with 6, which in the present context as a single-click beading

509809/0376

ceiling], protrudes from the upper edge of the jacket into the interior of the container and is also provided with a retaining bead 7, the position and shape of which corresponds exactly to the retaining bead 5 of the container jacket. The upper edge part 8 of the lid is bent outwards - corresponding to that of the upper part of the container jacket - and rests against the outer surface of the edge bead 4. The outermost section of the lid edge is formed by a securing tab 9, which also partially engages around the lower part of the edge bead 4 and represents an additional securing of the attached cover. Each container has one, ie a total of four, such tabs 9 per side wall, which at the same time also take on the function of the usual sealing. After these tabs have been bent open, they can no longer be pushed back into the illustrated securing position by hand, so that unauthorized opening of the container can easily be determined.

Between the bead 4 of the container jacket and the inner surface of the cover part 8 is a seal 10 arranged, which, for example, sprayed on. can. When the cover 6 is put on, the seal deforms 10 elastic and ensures a dust and liquid .proof Clasp. The seal 10 can au · *? Consist of rubber or a suitable plastic.

509809/0376

The lid 6 is also provided with a stacking bead 11, the proper stacking of the filled or closed, downwardly tapered container (see also-Pig. 1) permitted.

The cap described has over the known Eindrückdeckeln the advantage that it-is drawn through the interaction of the two beads 5 and 7 in the final phase of fitting in its final laser Eß, in which it is then firmly anchored. The pressing in of the cover 6 can easily take place automatically while pressing the tabs 9 at the same time. The rounded curves, which are often attached, give the closure a certain elasticity, so that it is not necessary to adhere to tight tolerances.

Another advantage of this construction is that the stacking bead 11 and the retaining bead 7 of the Lid can be produced in a single operation.

The disadvantage of this embodiment is, however, that in the retaining bead 5 of the container shell when filling a powdery or pasty medium the latter can accumulate, which makes the subsequent placement of the lid difficult or even impossible. This one The construction according to FIGS. 4 and 5 eliminates the disadvantage.

FIG. H again shows a container jacket 12,

509809/0376

on which a total of 13 designated cover is located. Here, too, there is a stacking icon for recording a second container 15 is provided and the edge area of the container jacket 12 is also here to one Edge bead formed l6. Both the container jacket 12 and the lid 13 are also in this case with a Retaining bead 17 and 18, respectively, but the two sikkcn are not in contrast to the embodiment according to FIG outside, but directed against the inside of the container. Though is used here for the production of stacking bead l4 and retaining bead 18 each requires a separate operation, but this minor disadvantage is caused by the following, considerable Advantages outweighed:

- The retaining bead 17 of the container jacket remains clean when the product is filled,

- In the event of an unintentional deformation of the container, the lid is not loosened, but only tighter pressed into the container jacket,

- When the empty containers are stacked, the inwardly directed retaining bead 17 provides additional security against slipping into one another due to possible inaccuracies in the conicity of the container shells.

cut is rolled up and thus forms a handle for easy removal of the lid. Since both the edge bead ΐβ as well as the rolled-up edge part designated by 20 the flap 19 are elastic, the flap can be elastic against the when the container is closed Press the lower part of the edge bead 16 so that a certain pre-tension acts between the two parts 16 and 20.

Here, too, a seal 21 is arranged between the cover and the annular bead 16. Since the lid 13 when put on is pulled down by the interaction of the two retaining beads 17 and l8 and held there, results an elastic compression of the seal 21 so that the container remains absolutely tightly closed.

In Fig. 5 are for those of FIG. 4 corresponding Parts keep the reference numbers already introduced. In this embodiment, the transition area is between the securing tab 19 and the upper part of the cover are weakened by a notch 22, which causes the tab to be bent over breaks off and an unauthorized opening of the container can be proven with even greater security.

If the containers described are to be opened, the securing tabs 9 are bent outwards (Fig. 3) and 19 (Fig. 4, 5) a slight lifting of the upper one Dcckclrandcc from the Aue ^ enfläclio doc liarid-. '/ UlEte =., Se that the lid can then be opened without opening by means of a V / er! · '-

can take off the witness.

In all the embodiments described, the lid can also be closed again in a dust-tight manner, only a slight deformation in the case of the safety flap remains behind. The securing tab can also be brought back into its starting position by means of a chamber v / earth.

The automatic closing of a container comprises the following two operations:

- Press the lid into the upper part of the container and

- Press on the securing tabs.

Both operations can easily be combined in a segment header with a subsequent step.

The container described, including the cover, can be made from sheet steel 0.5 thick, raw or painted, or from tinplate, for example. However, a combined pack made of hard paper and sheet steel can also be used, with the shell made of hard paper, the base and lid made of sheet steel.

Furthermore, the container and lid described can also be wholly or partially made of thermoset, consist of thermoplastic or glass fiber reinforced plastics, such as polyethylene, polyvinyl chloride, Polystyrene, polypropylene or polyamide.
