1 is a partial perspective view of the upper surface of a pallet of a container according to the present invention, showing approximately 1/4 of the total area.
1 is a pallet, which is made by deep drawing of a thermoplastic resin such as a fiber reinforced PP composite resin. Reference numeral 11 denotes three leg portions (only one is shown) protruding to the lower surface side so that the fork of the transportation forklift can be inserted into the space between the leg portions, and 17 is the fork lifting surface thereof. Reference numeral 12 indicates an outer peripheral wall surface, 12a indicates an outer peripheral wall surface.
An outer peripheral edge portion which is an end surface of the leg portion, 13 is formed in parallel in a direction orthogonal to the longitudinal direction of the leg portion 11, a load receiving surface on which a load is placed, and 14 is a sleeve provided so as to project to the inner wall side of the outer peripheral wall surface 12. A receiving seat, 15 is a reinforcing bead provided so as to bridge between the inner surface side of the outer peripheral wall surface 12 and the end wall surface of the load receiving surface 13, and 16 is an upper surface of a part of the sleeve receiving seat 14, and an inner surface of the outer peripheral wall surface 12. It is a stopper that is protruded upward with a predetermined space provided between the stopper and the side.

A plurality of sleeve receiving seats 14 are formed so as to project to the inner wall side of the outer peripheral wall surface 12, and the lower end of the sleeve is placed on the upper surface 14a and assembled. Its shape is a trapezoid whose lower part is larger than its upper part as shown in FIG. By doing so, even if the lower end of the sleeve is placed on the upper surface and weight is applied, the load on the bottom surface of the pallet 1 is dispersed and the strength can be increased. Further, the sleeve receiving seat 18 is formed near the outer peripheral wall surface parallel to the longitudinal direction of the load receiving surface 13,
The upper surface 18a is the upper surface 14 of the sleeve receiving seat 14.
Set to the same height as a.

FIG. 3 shows a sleeve according to an embodiment of the present invention. Reference numeral 32 denotes a sleeve, and a lower end edge 32e thereof has a flat linear shape without a cut or the like as in the conventional case as is clear from the drawing. When assembling to the pallet 1, it is not inserted until it reaches the bottom surface of the pallet as in the conventional case, but as described above, the sleeve receiving seat 14,
This is because they are mounted on the upper surfaces 14a, 18a of the 18. Upper surfaces 14a of the plurality of sleeve receiving seats 14 and 18,
Of course, all the levels of 18a are the same level.

A stopper 16 is formed on the upper surface 14a of a part of the sleeve receiving seat 14. The stopper 16 is a sleeve 32 mounted on the upper surface 14 a of the sleeve receiving seat 14.
It serves as a guide when the lower end edge 32e of the above is inserted, and prevents the sleeve from slipping off the upper surface 14a due to some reason. Therefore, a size is set between the stopper 16 and the inner wall side of the outer peripheral wall surface 12 so that the thickness of the sleeve 32 is sufficiently received.

The surface of the outer peripheral edge portion 12a which is the end surface of the outer peripheral wall surface 12 and the load receiving surface 13 are level with each other. By using the same surface, even if a large number of pallets 1 are piled up during storage or transportation, the state is stable.
It will not easily collapse.

The reinforcing bead 15 provided so as to bridge between the inner surface side of the outer peripheral wall surface 12 and the end wall surface of the load receiving surface 13 in the longitudinal direction is formed so as to intersect the longitudinal direction of the leg portion 11 at an angle. To do. In the example of FIG. 1, the reinforcing beads 15 are provided in various directions, but the reinforcing beads 15 may be parallel to each other as long as they obliquely intersect the longitudinal direction of the leg 11.

FIG. 2 is a partial perspective view of the bottom surface of the pallet of the container of the present invention for explaining the back surface side of the above-mentioned oblique reinforcing bead 15, and shows only a part thereof. 11
Is one of the three legs described above, and 25 is a groove on the lower surface side that is formed when the reinforcing bead 15 is formed on the upper surface by deep drawing of a thermoplastic resin. However, both are set so as to obliquely intersect the longitudinal line of the leg 11.

Thus, by setting the reinforcing beads 15 so as to obliquely intersect the longitudinal line of the leg portion 11, the groove 25 on the lower surface side also becomes oblique, and the roller of the roller conveyor which is generally used is often used. Pallet 1 above
Even if the pallet 1 is rolled and transported, the roller does not enter the groove 25 and the pallet 1 does not move up and down, so that much noise is not generated.

[0023]

As described above, according to the present invention, since the sleeve receiving seat for inserting and assembling the lower end edge of the sleeve into the outer periphery of the pallet is provided on the inner wall of the outer periphery of the pallet, the lower end of the sleeve is cut or cut. No notches are required, assembly work is easy, and work time can be shortened.

Further, also on the sleeve side, the step of forming a notch or a notch at the lower end is not necessary, so that the shape is simple and it is easy to manufacture.

Further, there is an effect that the load applied from the lower end of the sleeve to the pallet surface is dispersed, and the damage is less likely to occur.

Since the sleeve receiving seat has a trapezoidal shape in which the lower part is wider than the upper part, the load applied to the receiving seat is dispersed in the lower part, and there is an effect that deformation or damage of this part or its periphery can be prevented.

Since the stopper is extended upward on the upper surface of the sleeve receiving seat, it can be easily used as a guide when assembling the sleeve, and when the lower end of the sleeve is placed on it, it will slip off and fall off. There is nothing.

Since the outer peripheral edge surface of the pallet and the seat surface of the load receiving seat, which is a surface for placing an object on the pallet, have the same height, the container is stable during the stacking and the collapse is also stable during the stacking of the pallets. It is difficult to store, so it is easy to store.

A reinforcing bead is provided between the inner wall surface of the outer peripheral edge of the pallet and the end faces of a plurality of load receiving seats formed in parallel in the outer periphery of the pallet. The reinforcing bead is formed from the bottom surface of the pallet formed for inserting the fork of the forklift. The pallet is set at the factory because the projecting leg is diagonally intersected with the longitudinal direction of the leg and the directions of the reinforcing beads are parallel to each other or random with no mutual relation. When the roller conveyor is used to move the inside of the pallet, the groove on the lower surface of the pallet does not fall into the roller to generate noise, and the quietness in the factory can be maintained.
