Description

[Detailed description of the invention] The present invention relates to a packaging device used for washing machines, dryers, etc., and in particular relates to an improvement of a packaging base consisting of a cushioning material that receives the load of the product and a frame bottom plate that holds the cushioning material. be.

Conventionally, this type of packaging base, as shown in Fig. 1, consists of a box 1' made of cardboard or the like, a cushioning material 2',
3' is attached with adhesive. However, this configuration does not work well when making a box out of corrugated cardboard.
It is necessary to join the joints with wire or adhesive, which has the disadvantage of poor workability. Furthermore, when the packaging base is disposed of, it has drawbacks such as poor disassembly because it is fixed with adhesive or wire.

In view of the above drawbacks, the present invention aims to provide a device that does not require wires or adhesives for fixing, is easy to assemble, is durable, and is easy to dismantle when discarded. .

In the present invention, the packaging base is constructed by combining a frame bottom plate made of corrugated cardboard and two cushioning materials made of styrofoam, and the two opposing sides of the frame bottom plate are bent upward to form two cushioning materials. A rising side is formed, cushioning materials are arranged on both sides of the frame bottom plate so as to span between the two rising sides, arm portions are provided at both ends of the cushioning material, and a recess is formed on the upper surface of each arm portion, An engaging tongue piece with a cut line and a bending line that can be engaged with the recess is formed on the two rising sides, and the engaging tongue piece is bent and fitted into the recess to connect the assembled frame bottom plate. The packaging device is characterized by combining two cushioning materials.

Hereinafter, one embodiment of the present invention will be explained in Figs. 2 and 3.
This will be explained using FIG.

FIG. 2 shows a packaging base 1 according to the present invention. This packaging base 1 is made by combining a frame bottom plate 2 made of cardboard or the like and cushioning materials 3 and 4 made of styrofoam or the like. Third
The figure shows the main parts before the frame bottom plate 2 and the cushioning material 3 are combined. The cushioning material 3 has arm portions 3-1 and 3- at both ends.
It has 2. The cushioning material 4 also has arm parts 4-1, 4- at both ends.
It has 2. There are protrusions 3 on both end edges of the cushioning materials 3 and 4.
-3, 3-4, 4-3, 4-4 are formed. The protrusion height of this protrusion is approximately equal to the thickness of the frame bottom plate 2.

Recesses 3a, 3b, 4a, 4b are formed on the upper surfaces of the arms 3-1, 3-2, 4-1, 4-2.

The frame bottom plate 2 has a rising side 1-1 with both sides bent.
1-2. An engaging tongue piece 1 is provided on the rising side 1-1.
-1a, 1-1b and the rising edge 1-2 are provided with engaging tongue pieces 1-2a, 1-2b.

Engagement tongue pieces 1-1a, 1-1b, 1-2a, 1-
2b is formed with cut lines ○A, ○B and bending lines ○C.

Place the cushioning materials 3 and 4 on both ends of the frame bottom plate 2, and
-1, 3-2, 4-1, 4-2 rising edge 1-
1 and 1-2 on both sides. Rising edge 1-
Both end surfaces of 1 and 1-2 have protrusions 3-3, 3-4, 4-
3, 4-4, and the cushioning materials 3, 4 are positioned with respect to the frame bottom plate 2.

After this, the engaging tongue pieces 1-1a, 1-1b,
Bend 1-2a and 1-2b inward to form the recess 3.
a, 3b, 4a, 4b and engage.
Through this engagement, the frame bottom plate 2 and the cushioning materials 3, 4 are connected.

FIG. 4 shows the packaging of the product, in which the product 5 is placed on the packaging base 1. Upper cushioning materials 6 and 7 are placed on both shoulders of the product, and an outer box 8 is slipped over the product 5. The product 5 is packaged by wrapping the plastic band around the outer box 8 and around the bottom of the packaging base 1 and tightening it.

Next, the functions and effects of one embodiment of the present invention will be described.

Protrusions 3-3, 3 are provided at both end edges of the cushioning materials 3, 4.
-4, 4-3, 4-4 are provided, and the projecting height of these protrusions is set to about the thickness of the frame bottom plate 1, so the rising sides 1-1, 1-2 of the frame bottom plate 1 are Do not protrude beyond both ends of the cushioning materials 3 and 4. Exterior box 8
When placing the product 5 on top of the product 5, the outer box 8
The lower opening edge can be smoothly covered with the rising sides 1-1 and 1-2 without getting caught.

The packaging base 1 is a combination of a frame bottom plate 2 made of cardboard or the like and two cushioning materials 3 and 4 made of styrofoam, and an engaging tongue piece 1 of the frame bottom plate 2 is assembled.
-1a, 1-1b, 1-2a, 1-2b are fitted into recesses 3a, 3b, 4a, 4b and connected. This eliminates the need for adhesives and wires, saving material costs. Moreover, when discarding, the engaging tongue pieces 1-1a, 1-1b, 1
By raising -2a and 1-2b, the frame bottom plate 2
Since the cushioning materials 3 and 4 can be disassembled, disposal work is easy.

The packaging base 1 has a structure in which the bottom plate portion of the frame bottom plate 2 is surrounded by a wall around the two cushioning materials 3 and 4 and the two rising sides 1-1 and 1-2 of the frame bottom plate 2. It's getting stronger because of it. Moreover, since there is no need to provide a rising edge on the frame bottom plate 2 where the cushioning materials 3 and 4 are placed, the material for the frame bottom plate 2 is reduced accordingly, which is economical.

Since the lower part of the outer box 8 is an opening, it is weak by itself. The packaging base 1 is strong as described above, and this packaging base 1 is used as the outer box 8.
It will fit inside the bottom of the outer box 8.
The lower part is reinforced.

Protrusions 3-3 provided on both end surfaces of the cushioning materials 3, 4,
Both end surfaces of rising edges 1-1 and 1-2 come into contact with the inner end surfaces of 3-4, 4-3 and 4-4, and the cushioning materials 3 and 4 are positioned on the frame bottom plate 2, so that the cushioning It is easy to assemble the materials 3 and 4 and the frame bottom plate 2.

As described above, the packaging device of the present invention has a packaging base constructed by combining a frame bottom plate made of corrugated cardboard and two cushioning materials made of expanded polystyrene, and has two opposing ends of the frame bottom plate. The sides are bent upward to form two rising sides, and cushioning materials are arranged on both sides of the frame bottom plate so as to span between the two rising sides. Arms are provided at both ends of the cushioning material, and each arm A recess is formed on the top surface, and an engaging tongue piece with a cut line and a bending line that can be engaged with the recess is formed on the two rising sides, and the engaging tongue piece is bent and fitted into the recess to be assembled. It is characterized by combining a frame bottom plate with two cushioning materials.

According to this configuration, the following advantages can be obtained.

(1) The cushioning material and the frame bottom plate are connected by fitting the engaging tongue of the frame bottom plate into the recess of the cushioning material, so no adhesive or wire is required.

(2) By removing the engaging tongue from the recess, the cushioning material and frame bottom plate can be disassembled, making it easy to dispose of.

(3) Since the bottom plate of the frame bottom plate is surrounded by two cushioning materials and a wall around the rising edge, it is strong as a packaging base.

When combined with an outer box for product packaging, the packaging base serves to reinforce the lower part of the outer box.
