Abstract

PURPOSE: To prevent the slip of a shrink film when a palette and a cargo are packed in the film, in a palette made of a synthetic resin having upper and lower panels and the side panels connecting them, by providing a recessed part having specific depth to each of the side panels 4 and providing small projections to the recessed part. CONSTITUTION: A palette 1 made of a synthetic resin has an upper panel 2, a lower panel 3 and side panels 4 connecting them. A recessed part 5 having a part with a depth of 3-10mm is provided to each of the side panels 4 and small projections 6 are provided to the recessed part 5 in a strip or spot like state. The slip-up of a shrink film at a time of packing is effectively prevented by the small projections 6 and the stable winding-up of the film is ensured. When the height of the small projections 6 is set to 1.0-3.0mm, the excellent anti-slip effect of the shrink film can be obtained. The small projections 6 are formed so as to have a surface curved shape to prevent the damage of the shrink film.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin pallet, and more particularly to a synthetic resin pallet which can be wrapped in a shrink film to prevent collapse of loads.

[0002]

2. Description of the Related Art Conventionally, a method has been adopted in which a pallet and a load are wrapped in a shrink film and integrated so as to prevent the load from collapsing. Then, in order to prevent the shrink film from coming off from the pallet, a wooden pallet or a synthetic resin pallet having a concave portion on the side surface is used.

[0003]

Conventional synthetic resin pallets are used for various purposes because they can be manufactured easily and inexpensively. However, in the case of a synthetic resin pallet, the shrink film is slippery, and the shrink film is not sufficiently fixed in the synthetic resin pallet, and the effect of preventing collapse of the load is insufficient. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a synthetic resin pallet that has a high effect of preventing load collapse and can be shrink-wrapped.

[0004]

As a result of intensive studies to solve the above-mentioned problems, the inventors of the present invention have formed a concave portion having a specific shape on the side surface of a pallet made of synthetic resin, and further providing a small protrusion in the concave portion. By doing so, it was found that the shrink packaging can be prevented from slipping and rising, and the effect of preventing load collapse can be significantly improved. That is, the present invention provides a synthetic resin pallet having an upper surface plate, a lower surface plate, and a side surface plate connecting these, and the side surface plate is provided with a recess having a portion having a depth of 3 mm to 10 mm, and the recess has a small protrusion. The present invention relates to a synthetic resin pallet characterized by being provided with, and a synthetic resin pallet as described above characterized in that it is provided in a state in which small projections are scattered or in a band shape.

[0005]

An embodiment will be described with reference to the drawings. FIG. 1 is a side view showing an example of the pallet of the present invention. The synthetic resin pallet 1 of the present invention has an upper surface plate 2, a lower surface plate 3 and a side surface plate 4 connecting them. The side plate 4 is provided with a recess 5 having a portion having a depth of 3 mm to 10 mm, and the recess 5 is provided with a small projection 6. FIG. 7 is an enlarged view of a corner portion of the pallet of FIG. 1 and is characterized in that the recess 5 has a portion having a depth of 3 mm to 10 mm, for example, a portion having a length (a) in FIG. 7 of 3 mm to 10 mm. And Then, the small projection 6 is provided in the concave portion 5, and the small projection 6 is provided in a band shape. The small protrusions may be provided in a scattered state as shown in FIG. 9, and by providing the small protrusions in a scattered state or in a belt-like state, the shrinkage of the shrink film packaging is effectively prevented. be able to.

In the present invention, the length, width and height of the small projections can be set as appropriate, but among them, the small projections having a height of 1.0 mm to 3.0 mm are effective for preventing the shrink film from slipping. Is preferable because it is large. Further, it is preferable that the surface shape of the small protrusions is a curved surface shape so as not to break the shrink film. The small protrusion of the present invention can form a passage for letting air out between the film and the pallet when the film is wound around the pallet, and also has an effect of bringing the film into close contact with the pallet.

The recess in the present invention may be provided over the entire circumference of the side surface of the pallet or may be provided partially. However, in order to prevent the shrink film from slipping, it is provided at the corner portion formed between the side surfaces. is important. Also,
The small protrusion of the present invention may be provided at any position of the recess,
It is preferable to provide the recesses in the corners formed by the side surfaces, because the effect of preventing the shrink film from slipping is further increased.

The recess in the present invention has a depth of 3 mm to
It is necessary to have a 10 mm section. If it is less than 3 mm, the shrink film easily comes off the pallet,
If it exceeds 10 mm, the strength of the pallet against vertical compression is reduced, or it becomes difficult to release the product from the mold after molding.

FIG. 4 is a side view showing another example of the pallet of the present invention, and FIG. 8 is an enlarged view of a corner portion of the pallet of FIG. In FIG. 8, the small protrusions 6 are provided in a striped state, but they may be provided in a scattered state as shown in FIG.

11 and 12 show an example of a state in which the pallet of the present invention is hollow-molded and a state in which the pallet is removed after the hollow-molding. 11 and 12, the slide mold 11 is used to mold a pallet having concave portions and small protrusions in one hollow molding, and by moving the slide mold 11 when removing the pallet after the hollow molding. A recess can be provided.

Various synthetic resins can be used for the pallet of the present invention, and among them, polyolefin resin is preferable. Further, in the case of a pallet molded by blow molding, high-density polyethylene and polypropylene are preferable because they are easy to mold and have good mechanical properties.

[0012]

According to the present invention, the following effects are exhibited. (1) When wrapping a pallet and luggage with a shrink film, the film does not slip and can be easily rolled up. (2) After the shrink film is packaged, the film is securely fixed to the pallet, and it is possible to prevent the film from slipping up. (3) When a pallet packed with shrink film is handled by a forklift or the like, the film can be prevented from coming off the pallet even if a large tensile stress is applied when inserting the fork into the film.
