Abstract

A pallet container (13) has a pallet (15) on which there is a plastic container (17) with a grid (19) around it. The grid (19) consists of vertical tubes (21) and horizontal connecting elements (23) which are welded to each other. The connecting elements (23) are made up of profiled strips (25), in which the profiling runs in a direction transverse to the vertical tubes (21). The strips (25) are provided with flat surfaces which run in a vertical direction and are in contact with the tubes (21). The tubes (21) are round and are provided with a flattened surface that is in contact with the flat surfaces of the strips. This pallet container is simple to manufacture, inexpensive and strong.

Description

Pallet container
BACKGROUND OF THE INVENTION:
Field of the invention
The invention relates to a pallet container comprising a pallet on which there is a container which is enclosed at least on the side walls by a grid that is coupled to the pallet, which grid comprises a number of mainly vertical parallel tubes, spaced horizontally at a distance from each other, as well as a number of connecting elements, which are attached to the tubes and connect the tubes to each other. More particularly, the invention relates to a pallet container with a rectangular plastic container, especially for storing liquids, in which the grid is fitted closely around the container. The grid serves to protect the container and make it easier to stack.
Prior art
Such a pallet container is generally known. With the known pallet container the connecting elements are also made up of tubes which are welded to the vertical tubes.
In order to see that the grid does not occupy much space, the horizontal and vertical tubes are indented at the welds, so that the grid's thickness at a joint is only a little more than the thickness of a tube. The disadvantage of the known pallet container is that the grid is relatively difficult to make. Indenting the tubes needs to be done precisely and the points where the tubes are indented need to be determined exactly. In addition, the tubes are spot welded as a result of which the welding needs to be executed precisely. Furthermore, the tubes are weakened by the indentations as a result of which the stacking strength of the pallet container decreases.
Summary of the invention
An objective of the invention is to provide a pallet container of the type described in the preamble in which the grid is easier to make and its stacking strength is greater than the known pallet container, while the thickness of the grid is almost as much as that of the known pallet container. To this end, the pallet container according to the invention is characterized in that the connecting elements are made up of strips. The thickness of the pallet container's grid at a joint is equal to the thickness of a tube plus the thickness of a strip. Because the strip is relatively thin with respect to the tube, the pallet container's grid according to the invention is only a little thicker than that of the known pallet container. However, because the vertical tubes are not indented, the stacking strength is greater than that of the known pallet container. Furthermore, the pallet container according to the invention is easier to make than the known pallet container because the tubes do not have to undergo special processing (indenting).
An embodiment of the pallet container according to the invention is characterized in that the strips are profiled strips, in which the profiling runs mainly in a direction transverse to the vertical tubes. Because of this, the strength of the pallet container is increased considerably while the thickness of the grid will only be a little greater.
A further embodiment of the pallet container according to the invention is characterized in that the profiled strips are flattened at the joints with the vertical tubes. Because of this the strips can bend more easily, which is favourable when a pallet container falls, because in that case, the pallet container can deform more easily and, therefore, can absorb more energy from the fall. In addition, because of this the thickness of the grid decreases.
Preferably the strips are provided with flat surfaces which run mainly in a vertical direction and are in contact with the tubes. Because of this, the tubes are in contact with the strips along a line, as a result of which it is easier to weld them to each other and the welds are stronger than the spot welds of the known pallet container.
In order to improve further the connection between the tubes and the strips, the tubes are preferably provided with at least one flat surface that is in contact with the strips. Because of this, the tubes and the strips are in contact with each other along those surfaces, as a result of which they can be attached to each other even better. The tubes are preferably round and provided with a flattened surface. The tubes may also be triangular or have more sides. Brief description of the drawings
The invention will be elucidated more fully below on the basis of drawings in which embodiments of the pallet container according to the invention are shown. In these drawings:
Figure 1 shows a known pallet container in perspective; Figure 2 shows a detail of the known pallet container at the joint of the grid's tubes; Figure 3 is a view in perspective of an embodiment of the pallet container according to the invention;
Figure 4 shows a detail of the attachment of a vertical tube to a horizontal strip of the pallet container according to the invention;
Figure 5 is a cross-section of the attachment along the line V-V in Figure 4; and
Figure 6 shows a detail of the attachment of the tube to the strip of a further embodiment of the pallet container according to the invention.
Detailed description of the drawings
In Figure 1 a known pallet container 1 is shown. The pallet container 1 has a pallet 3 on which there is a plastic container 5. There is a grid 7 that is attached to the pallet 3 around the container 5. The grid 7 consists of a number of horizontal and vertical tubes 9 and 11 respectively. At the points where the horizontal and vertical tubes 9, 11 cross each other, the tubes are indented and welded to each other, see Figure 2.
An embodiment of the pallet container 13 according to the invention is shown in Figure 3. This embodiment also has a pallet 15 on which there is a plastic container 17 around which is a grid 19. In this embodiment the grid 19 consists of vertical tubes 21 and horizontal connecting elements 23. These connecting elements 23 are made up of profiled strips 25, in which the profiling runs in a direction transverse to the vertical tubes 21.
The strips 25 are provided with flat surfaces 27 which run in a vertical direction and are in contact with the tubes 21, see Figure 4. The tubes 21 are round and provided with a flattened surface 29 that is in contact with the flat surfaces 27 of the strips. A cross-section of the joint along the line V-V in Figure 4 is shown in Figure 5.
The profiled strips 25 can be situated on the outer side of the vertical tubes 21 (as shown in Figure 3) or on the inner side. In the last case, the container 17 can be provided, if necessary, with recesses (not shown) in which the strips 25 are then situated.
A detail of the attachment of a tube 31 to a strip 33 of a further embodiment of the pallet container according to the invention is shown in Figure 6. In this detail the vertical tubes 31 have a square cross-section, through which they are also in contact with the strip 33 along a surface.
Although in the above the invention is explained on the basis of the drawings, it should be noted that the invention is in no way limited to the embodiments shown in the drawings. The invention also extends to all embodiments deviating from the embodiments shown in the drawings within the context defined by the claims. Thus the strip can be situated on the side away from the vertical tubes like that shown here as well as on the side next to the tubes or on both sides. Furthermore, the vertical tubes may also have other shapes such as one having a hexagonal cross-section or even more sides than that.
