Description

in 146883

The invention relates to a pallet container of the kind specified in the preamble of claim 11.

Eg. from DE-OS 2,417,599 such a pallet container is known, the carrying rack of which is made up of two interconnected cardboard boxes, 5 of which the inside contains the actual container which is constituted by a plastic bag. In the space between the two cardboard boxes are inserted vertical wooden supports extending down below the bottom of the outer box, the lower parts of which can be inserted into corresponding openings in the pallet itself to prevent displacement between it and the support frame. Each two opposite wooden supports are at their upper end interconnected by means of iron ribbons, so that the weak carrier carrier itself can withstand the pressure of the filled plastic bag. For retaining the support frame for the pallet, serve the leaded iron-15 belt. However, such pallet containers are only suitable as a one-time package, cannot be stacked over one another, are extremely sensitive to side effects, and thus cannot withstand falls even from low altitude. In addition, the carrier rack takes up a relatively large unused volume.

For example, from DE-GBM 1.943 · 386 another pallet container of the specified kind is known. This pallet container also has a carrying rack with large external dimensions and of a very complicated and expensive design in relation to the actual container. Namely, the carrier rack is composed of corner posts interconnected by means of an upper and a lower transverse frame and further provides a middle grid disposed above the lower transverse frame consisting of steel straps fastened to the posts. The container itself resting on the intermediate grate consists of fiberglass reinforced plastic, such reinforcement is necessary as the container is loosely mounted in the support frame and only at a few points at the bottom and at the four posts is supported by rubber buffers. This well-known pallet container, which even in empty condition has a relatively large weight, is not suitable for longer transport and not at all as disposable packaging.

The object of the invention is to provide a pallet container of the specified type which is stackable, in all cases in up to three layers, is suitable as well as disposable packaging and for more permanent troughs, enables a large utility volume of the actual container and is simple in making.

According to the invention, this is achieved by the design according to the characterizing part of claim 1.

5 The use of a metal plate casing ensures a high stability and strength and minimum volume requirements of the carrier frame, and, even when the weight is low, allows the pallet containers to be stacked at least in three layers, and furthermore due to the close installation between the casing and the actual container can be made thin, which is a condition for its use as disposable packaging, also because metal sheet itself is a relatively inexpensive material. The low weight, for example, when the container can hold 600 liters, constitutes only% kg »and when the container can hold 800 liters, approx. 66 kg, furthermore, means that the empty container can easily be transported by a single man, e.g. using a sack truck. This may be important in connection with the permanent use of the pallet container, as its removal does not require waiting for a forklift to become vacant.

In addition, according to the invention, the design can be as defined in claim 2, whereby very high strength is combined with good durability.

In addition, according to the invention, the design can be as claimed in claim 5, thereby not only achieving a strength increase, but also preventing sharp edges from being able to damage people and things.

In this case, the design can furthermore be as set out in claim 4, thereby avoiding special attack means for the cleat plates and these are further arranged so that the size of the pallet top can be used to the best possible extent.

Further, according to the invention, the configuration may be as claimed in claim 5, whereby not only a shape-fitting support is also obtained from the bottom of the actual container, but also absorption of vibrations produced during transport as a result of fluid movements within the container which may otherwise be harmful. 35 for stability.

Further, according to the invention, the design may conveniently be as set forth in claim 6, whereby not only is it achieved that the filling opening or socket with associated lid can be arranged lower than the upper surface of the cover, but also that it is ensured that the container is completely filled inside. in this adjacent to the recess there are air pockets that can absorb as a result of, in particular, during transport, temperature fluctuations, the volume changes of the liquid contained in the container, so that no pressure is created inside the container to cause stability debilitating bulges.

Finally, according to the invention, the design can be as claimed in claim 7, so that the pallet container can also be lifted with a crane or running cat without having protruding parts, the lifting forces being directly transferable to the cover of the casing, so that the thin container itself, that it is directly affected by the lifting forces, does not get its material overloaded.

The invention will be explained in more detail below with reference to the drawing, in which: FIG. 1 is a side view of an embodiment of a pallet container according to the invention; FIG. 2 is the one shown in FIG. 1 is a top view of the pallet container, FIG. 3 the stream of FIG. 1, seen from the left side of FIG. 1, and FIG. 4 shows, on a larger scale, a section IV of FIG. Third

A rectangular square plastic container 1, e.g. of polyethylene, with rounded corners is tightly enclosed by a galvanized steel sheet 25, which not only allows stacking up to three layers of the containers over one another, but at the same time serves as a "support cross" for the plastic container 1. The casing consists of a metal plate sheath 2, a cover 3 and a bottom 4, the cover and bottom being connected to the sheath 2 by roller welding.

The plastic container 1 has at the center of its upper wall a closable filling opening 5 which in the illustrated embodiment is closed by means of a screw cap 6, but may also be closed with a plastic cap with bayonet socket. At its deepest location, the container 1 has an outlet opening 7 'which is also closable by means of a screw cap 8 and further so with a plastic-cached film not shown, that after the screw cap 8 has been turned off, an appropriate drainage fitting, e.g.

4 146883 and. insert or screw-in cock. In the vicinity of the fill and outlet openings 5 and 7, the cover 3 and the casing 2 have corresponding recesses 9 and 10, respectively, the edges 11 of which are dry-cut to avoid sharp edges.

The unit consisting of the plastic container 1 and the casing 2,3,4 is attached to a flat pallet 13 by means of four cleat plates 12, e.g. by means of nails or screws 14 · The cleat plates 12 engage a roller bead 15 on the bottom 4 of the sheath at each of the four rounded corners of the sheath. Also the cover 3 has a roll-10 bead 15.

As shown in FIG. 1 to 3, the upper wall of the plastic container 1 * bears a transverse recess 16, at the center of which the filling opening 5 is located. At the transition points 17 of the recess 16, the vertical longitudinal median plane 15 of the container 11 is formed by suspension lugs 18. The container 1 is supported by a polystyrene foam support ring 19, which support ring 19 abuts both the lower rounded edge of the plastic container l1 and the casing.

To secure the top and bottom screw closures 20 and 6 respectively, sealing bags 20 are provided.

As a result of the "support cross" formed by the sheath for the pallet container, the inner plastic container 1 can be relatively thin-walled and thus simply manufactured by blowing. This results in a substantial cost reduction of production, so that the entire pallet container can be used as disposable packaging, especially in the case of long transport routes, e.g. on transport to overseas countries. For shorter distances, the pallet container can e.g. follow the first delivery, set up with the consumer and 30 later replenished from the tanker in the case of the same liquid, e.g. colors, lubricating or hydraulic oils or acids.

Thus, by means of the present invention, there is provided a practical pallet container which can be used both as a disposable container and as a container for repeated use, and which can be lifted both by crane or trolley and by forklift. For example, the holder may are manufactured in three sizes with a room capacity of 600, 800 and 1000 liters, all containers having the same basic grid dimensions, pallet dimensions, while differing only in height.
