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 a copying machine, a printer, a facsimile, a scanner and the like.

[0002]

2. Description of the Related Art Conventionally, a cardboard pallet with a base sheet for packaging is used for packaging of a copying machine, a printer, a facsimile, a scanner and the like. A product, which is an example of an article to be packaged, is placed on the cardboard pallet with the packaging base sheet, and covered with an outer box from above.

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

In the cardboard pallet 1 with a base sheet for packaging, a base pad 4 made of foamed plastic or the like is used as a cushioning material during transportation. As shown in FIG. 7, the base pad 4 is attached to a 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 collect and recycle foamed plastics has been increasing.

However, in the conventional cardboard pallet 1 with a base sheet for packaging as shown in FIG. 7, the base pad 4 is adhered to the base sheet 3 by the adhesive 5, so that the base sheet 3 It is not easy to peel off. Furthermore, the base pad 4 peeled off from the base sheet 3 has a cardboard piece or adhesive 5 peeled off from the base sheet 3 adhered thereto. These cardboard pieces and the adhesive 5 become impurities when the base pad 4 is melted and hinder recycling.

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

[0008]

According to a first aspect of the present invention, there is provided a cardboard pallet with a base sheet for packaging according to the invention, a base sheet fixed to an upper surface of the pallet, a cushioning material for supporting an article to be packaged, and A flap extending from two opposing sides is bent into a vertical cross-sectional shape corresponding to a predetermined vertical cross-section of the cushioning material, and has a groove formed on the base sheet.

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

According to a second aspect of the present invention, there is provided the cardboard pallet with the base sheet for packaging according to the first aspect, wherein the pallet is formed to protrude into the groove, locks the cushioning material, and extends the length of the groove of the cushioning material. It has a positioning piece for positioning the position in the direction.

Therefore, since the longitudinal position of the groove in the groove of the cushioning material is fixed by the positioning piece, the cushioning material does not shift along the longitudinal direction of the groove.

1 to 6 show an embodiment of a cardboard pallet with a base sheet for packaging according to the present invention.
It will be described based on. The same parts as those described in the conventional example are denoted by the same reference numerals, and detailed description is 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 the present embodiment, the pallet 2 is also made of cardboard.

First, the base sheet 3 has a bottom surface which is slightly smaller in area than the pallet 2 and has flaps 6 extending from two opposite sides of the bottom surface (see FIG. 1). At the front end of the flap 6, a fixing claw 8 is provided so as to fit into a fixing hole 7 formed on the bottom surface. A substantially central portion from the base of the flap 6 to the tip is a portion serving as a bottom surface of the groove in which the base pad 4 is fitted. The bottom has two H-shaped cuts. When these cut portions are bent and raised, the base pad 4
Is formed.

Further, the flap 6 of the four sides around the bottom surface is
A mounting piece 11 having a mounting hole 10 is provided on the other two sides on which the is formed.

Each of the flaps 6 is moved from a state where the cardboard pallet 1 with the packaging base sheet shown in FIG.
It is bent at each of the two opposing sides and raised substantially perpendicular to the bottom surface, and further bent inward at a predetermined height from each of the bent sides by approximately 90 ° (see FIG. 2).

Here, the portion where the H-shaped cut is made is bent and raised, and a positioning piece 9 for positioning the base pad 4 is formed. The base pad 4 is positioned by sandwiching two opposing side surfaces between two positioning pieces 9. Each flap 6 is bent such that a portion to which the base pad 4 is attached is a bottom surface of the groove (see FIG. 3).

The shape of the bent flap 6 is fixed by inserting the fixing claw 8 at the tip of each flap 6 into the fixing hole 7 formed on the bottom surface (see FIG. 4).

The product A is placed on the cardboard pallet 1 with the base sheet for packaging formed as described above, and the upper pad 12 is attached to the corner of the product A as shown in FIG. It is 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 base sheet for packaging and the outer box 13 are fixed by fitting these holes and the mounting holes 10 and fitting a mold joint (not shown).

Here, the product A packaged with the cardboard pallet 1 with the base sheet for packaging and the outer box 13 is 40 cm long.
A drop test was conducted in which the product A was dropped 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 pad 4 falls obliquely in this manner, a lateral load is applied to the base pad 4. However, since the base pad 4 is fixed to both side walls of the groove formed by bending the flap 6 and the positioning pieces 9, the base pad 4 falls off the groove. And does not move along the groove.

According to the present embodiment, 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, can be easily collected and recycled. Further, in the present embodiment, the base pad 4 is sandwiched in the groove formed by bending the flap 6 into a waveform, so that the fixing claw 8 is removed from the fixing hole 7 and the bent flap 6 is only slightly extended. 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 the present embodiment. In practice, the groove formed by bending the flap 6 is fixed in position with the base pad 4 interposed therebetween. It should just be.

[0022]

According to the first aspect of the present invention, the base sheet fixed to the upper surface of the pallet, the cushioning material for supporting the article to be packaged, and the flaps extending from two opposing sides of the base sheet are formed of the cushioning material. And a groove formed on the base sheet by being bent into a longitudinal sectional shape corresponding to a predetermined longitudinal section of the material, so that the cushioning material can be fixed in the groove without using an adhesive, and Since no agent is used, the buffer material and the base sheet can be easily separated.

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