Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cardboard pallet with a packaging base sheet for packaging copying machines, printers, facsimiles, scanners and the like.

[0002]

2. Description of the Related Art Conventionally, a corrugated cardboard pallet with a packaging base sheet has been used for packaging copying machines, printers, facsimiles, scanners and the like. A product, which is an example of an article to be packaged, is placed on this cardboard pallet with a base sheet for packaging, and an outer box is covered from above to be packaged.

FIG. 7 shows an example of a cardboard pallet with a base sheet for packaging. The cardboard pallet 1 with a packaging base sheet is a pallet 2 made of wood,
The base sheet 3 made of cardboard is fixed.

The cardboard pallet 1 with a base sheet for packaging uses a base pad 4 formed of foamed plastic or the like as a cushioning material during transportation. As shown in FIG. 7, the base pad 4 is attached to the cardboard base sheet 3 with an adhesive 5.

[0005]

In recent years, environmental pollution due to disposal and incineration of foamed plastics has become a socially important problem, and the need to recover and recycle foamed plastics is increasing.

However, in the conventional cardboard pallet 1 with a base sheet for packaging as shown in FIG. 7, since the base pad 4 is attached to the base sheet 3 by the adhesive 5, the base sheet 3 to the base pad 4 are attached. It is not easy to peel off. Furthermore, the corrugated cardboard pieces and the adhesive 5 peeled from the base sheet 3 are attached to the base pad 4 peeled from the base sheet 3. These corrugated cardboard pieces and the adhesive agent 5 become impurities when the base pad 4 is melted and prevent recycling.

An object of the present invention is to provide a cardboard pallet with a base sheet for packaging in which the cushioning material is fixed to the base sheet without using an adhesive and the cushioning material can be easily removed from the base sheet.

[0008]

A cardboard pallet with a base sheet for packaging according to the present invention is a base sheet fixed to the upper surface of the pallet, a cushioning material for supporting an article to be packaged, and the base sheet. comprising a flap extending from the two opposing sides, and a groove the flap Ru formed on the buffer material of a given said base sheet Ru bent in the longitudinal sectional shape corresponding to the longitudinal section, both sides of the groove In front of the wall
The buffer material was sandwiched.

Therefore, since the cushioning material is fixed on both side walls of the groove and no adhesive is used, the cushioning material can be easily removed.

The invention according to claim 2 is the cardboard pallet with a base sheet for packaging according to claim 1, wherein the cardboard pallet is formed so as to project into the groove, and a cushioning material is locked to lengthen the groove of the cushioning material. It has a positioning piece for positioning the position in the direction.

Therefore, since the position of the shock absorbing material in the groove in the longitudinal direction is fixed by the positioning piece, the shock absorbing material is not displaced along the longitudinal direction of the groove.

BEST MODE FOR CARRYING OUT THE INVENTION One embodiment of a cardboard pallet with a base sheet for packaging according to the present invention is shown in FIGS.
It will be described based on. The same parts as those described in the conventional example are designated by the same reference numerals, and detailed description thereof will be omitted. In the present embodiment, the base pad 4 has a divergent shape,
The lower half of the base pad 4 is sandwiched between the side walls of the groove formed by bending the cardboard. Further, in this embodiment, the pallet 2 is also formed of cardboard.

First, the base sheet 3 has a bottom surface having a slightly smaller area than the pallet 2, and has flaps 6 extending from two opposite sides of the bottom surface (see FIG. 1). At the tip of the flap 6, a fixing claw 8 that fits into a fixing hole 7 formed on the bottom surface is projected. The substantially central portion from the base of the flap 6 to the tip is the portion that becomes the bottom surface of the groove into which the base pad 4 is fitted. This bottom has two H-shaped cuts. When the cut portion is bent and raised, the base pad 4
A positioning piece 9 for positioning is formed.

The flap 6 out of the four sides around the bottom surface
Mounting pieces 11 having mounting holes 10 are provided on the other two sides of the two sides where the mounting holes 11 are formed.

Each of the flaps 6 is provided with the packaging base sheet-attached cardboard pallet 1 shown in FIG.
Each of the two opposite sides is bent and raised vertically to the substantially bottom surface, and is further bent inward at a predetermined height from each of the bent sides by about 90 ° (see FIG. 2).

Here, the portion in which the H-shaped notch is formed is bent and bent to form a positioning piece 9 for positioning the base pad 4. The base pad 4 is positioned by sandwiching two opposing side surfaces with two positioning pieces 9. Each flap 6 is bent so that the portion to which the base pad 4 is attached becomes the bottom surface of the groove (see FIG. 3).

Then, the fixing claw 8 at the tip of each flap 6 is inserted into the fixing hole 7 formed in the bottom surface to fix the shape of the flap 6 formed by bending (see FIG. 4).

As shown in FIG. 5, the product A is placed on the cardboard pallet 1 with a base sheet for packaging thus formed, and the upper pad 12 is attached to the corner of the product A to form the outer box 13. Covered. The outer box 13 has a mounting piece 11
A hole (not shown) corresponding to the mounting hole 10 is formed. The cardboard pallet 1 with the packaging base sheet and the outer box 13 are fixed by fitting a joint (not shown) made of a mold by aligning these holes with the mounting holes 10.

Here, the product A packaged in the cardboard pallet 1 with the packaging base sheet and the outer box 13 is 40 cm.
A drop test was conducted by dropping the product A from a certain height to check whether the product A had any abnormality. FIG. 6 shows an example of the drop direction in the drop test. When the base plate 4 is thus obliquely dropped, a lateral load is applied to the base pad 4, but since the base pad 4 is fixed by both side walls of the groove formed by bending the flap 6 and the positioning piece 9, the base pad 4 falls off from the groove. It does not move along the groove.

According to the present embodiment, since the base sheet 3 made of cardboard and the base pad 4 made of foamed plastic are not fixed with an adhesive or the like,
It can be easily separated and therefore easily collected and recycled. Further, in the present embodiment, since the base pad 4 is sandwiched in the groove formed by bending the flap 6 in a wave shape, it is only necessary to remove the fixing claw 8 from the fixing hole 7 and to slightly extend the bent flap 6. The base pad 4 can be removed.

The shape of the base pad 4 and the method of bending the flap 6 are not limited to those in the present embodiment. In practice, the groove formed by bending the flap 6 sandwiches the base pad 4 and fixes the position. If you have.

[0022]

According to the first aspect of the invention, the base sheet fixed to the upper surface of the pallet, the cushioning material for supporting the article to be packaged, and the flap extending from two opposite sides of the base sheet , flap and a predetermined groove longitudinal sectional Ru bent in shape and Ru is formed on the base sheet corresponding to the longitudinal section of the cushioning material, said at both sidewalls of the groove
Since the cushioning material is sandwiched , it is possible to fix the cushioning material in the groove without using an adhesive, and since the adhesive is not used, the cushioning material and the base sheet can be easily separated. .

According to the second aspect of the present invention, since the positioning piece is formed so as to project into the groove and locks the buffer material to position the buffer material in the longitudinal direction of the groove, it is fitted into the groove. Since the position of the cushioning material in the groove in the longitudinal direction can be positioned in the groove, it is possible to prevent the cushioning material from being displaced along the groove.
