Description

[Detailed description of the invention] The present invention relates to a structure for connecting a skid to a bottom plate in a pallet for packaging containers, and more specifically, to a structure for connecting a skid to a bottom plate formed using three-layer corrugated cardboard as a material. It is something.

[Prior art]

The pallet that forms the bottom of containers for packaging heavy items such as materials for export is conventionally made of wood, i.e., a wooden pallet with skids nailed or umbrella nails to the base plate made of wood. It was hot.

Wooden pallets have the advantage of being strong against lamination, but they also have the following disadvantages:

In other words, there is a possibility that harmful organisms such as microscopic insects are living inside the tree, so it is necessary to fumigate it before exporting it. Although this is unavoidable in terms of epidemic prevention, it is not desirable for the operator as it naturally increases the number of steps and increases costs.

Another disadvantage of wooden pallets is that they are heavy.

In order to improve these shortcomings, attempts were made to use three-layer corrugated cardboard instead of wooden pallets. However, when fixing the skid to the bottom plate of a pallet made of three-layer corrugated cardboard, the mounting structure became a problem because nails, umbrella nails, etc. could not be used.

[Purpose of invention]

The purpose of the present invention is to provide a structure for connecting a bottom plate and skid with excellent strength without using nails.

[Structure of the idea]

That is, the present invention is characterized in that it is possible to connect the bottom plate and the skid by using fasteners, and it is also possible to obtain a packaging container pallet with excellent strength. Therefore, the gist of the present invention is that a skid formed in a prismatic shape is brought into contact with the back surface of a bottom plate formed in a rectangular shape using three-layer corrugated cardboard as a material so as to extend in the width direction of the bottom plate. A pallet for packaging containers has a bottom portion and a pair of left and right rising portions, which are bent into a U-shape, and a holding portion is integrally extended to both rising portions to form a stopper. The skid is held by the bottom part and the rising part of the metal fitting, and the holding part is made to protrude from the surface of the bottom plate and is bent at right angles along the same surface.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway perspective view of a pallet for packaging containers according to an embodiment of the present invention.

The pallet 1 is composed of a bottom plate 2 made of three-layer corrugated cardboard, a skid 3, and a fastener 4. Three-layer corrugated board is a 5-30 mm corrugated board in which three layers of corrugated reinforcing paper are laminated with flat paperboard interposed in between. The bottom plate 2 is formed into a rectangular shape with appropriate dimensions. Further, the skid 3 has a length approximately equal to the width of the bottom plate 2 and is formed into a prismatic shape. Although the material is not particularly limited, the skid 3 of this embodiment is formed by folding a three-layered cardboard into a U-shape and filling it with a filler. The bottom plate 2 and skid 3 are fixed by fasteners 4 with the opening side of the skid 3 in contact with the back surface of the bottom plate 2. That is, the fastener 4 is made of a band-like material and has a bottom portion 7 and a pair of left and right rising portions 8, 8, and is bent into a U-shape.
It is formed by integrally extending presser parts 9, 9 whose tips are cut out in an acute angle shape, and the bottom part 7 and the pair of left and right rising parts 8, 8 form a connection with the bottom surface of the skid 3. While holding both sides, the presser parts 9, 9 are made to penetrate the bottom plate 2 and protrude to the surface side, and the presser parts 9, 9 are bent at right angles along the surface of the bottom plate 2, and the presser parts 9, 9 are bent at right angles along the surface of the bottom plate 2. , 9 are bent at a right angle downwards to form a wedge piece 11.
, and is fixed by biting the wedge piece 11 downward into the bottom plate 2.

Figures 2 to 4 show each embodiment of the fastener, and in each figure, A is a perspective view showing the fastener 4 bent into a U-shape, and B is a perspective view showing the holding part. FIG. 3 is a perspective view showing a state in which the skid and the bottom plate are fixed by bending at right angles.

The stopper 4 in FIG. 2 has a bottom part 7 having the same width as the bottom surface of the skid 3, and rising parts 8 rising from both sides of the bottom part 7.
8. Consists of holding parts 9, 9 extending integrally from the rising parts 8, 8;
A notch 1 is formed at an appropriate angle of inclination at the tip of 9.
0,10 are formed.

That is, the tip portions of the presser portions 9, 9 are notched in an acute angle shape. Then, the tips of the holding parts 9, 9 are further bent at a right angle to form wedge pieces 11, 11, which are provided so as to be able to be stuck into the bottom plate 2 of the pallet.

In the stopper 4 shown in FIG. 3, serrated notches 10, 10 are formed at the tips of the holding parts 9, 9. That is,
The tip portions of the holding portions 9, 9 are notched in a sawtooth shape. Then, wedge pieces 11, 11 are formed by further bending the tip at a right angle, and these are attached to the bottom plate 2 of the pallet.
It is installed so that it can be pierced.

The stopper 4 in FIG.
A letter-shaped notch 10, 10 is formed. That is,
The tip portions of the holding portions 9, 9 are notched in a V-shape. Then, by bending the tip at a right angle, the wedge piece 11,
11 is formed.

The material of the fastener 4 is not particularly limited as long as it is a metal, but aluminum, iron, steel, copper, etc. are preferable.
As for the bending direction of the presser part 9 of the fastener 4, it is preferable to bend it inward so that the notches 10 and 10 face each other as in the examples shown in FIGS. It is also possible to bend it in the direction, and such a structure is also an embodiment of the present invention.
Of course, in that case, the bending direction of the wedge piece 11 is also reversed, so that the effect of piercing the bottom plate 2 can be obtained. The number of skids 3 is two or more, and the length is preferably the same width as the bottom plate. You can also make it easier to insert.

[Effect of idea]

The present invention has the following effects.

(a) Since it is made of three-layer cardboard, it is lightweight and does not require fumigation. Therefore, the manufacturing process is simplified, leading to cost reduction.

(b) In addition to being able to cover the weak point of three-layer corrugated board, where nails cannot be used, by using the fasteners, the tip of the holding part is formed with an acute notch, so that the tip can be directly connected It can be inserted into the bottom plate of the pallet. That is, it is not necessary to previously open the insertion holes for the fasteners in the bottom plate of the pallet, and the workability can be improved.

(c) By forming a wedge piece on the fastener and inserting it into the bottom plate of the pallet, the skid can be fixed more firmly.
