Abstract

PROBLEM TO BE SOLVED: To provide an envelope which is foldable in any directions, inexpensive, recyclable and friendly to environments by giving cushioning property by a corrugating medium base paper entirely made of embossed waste paper. SOLUTION: The envelope comprises, on a technological assumption, a surface piece and a rear piece formed as a rectangle wherein the pieces are stuck to each other, and three sides of the surface and rear pieces which are stuck are closed, while an opening side of either the surface piece or the rear piece is formed with a lid piece extending. In this case, stuck surfaces of the surface piece and the rear piece are formed of the corrugating medium base paper made of embossed waste paper.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an envelope having a cushioning property against a storage object which is vulnerable to an impact or the like.
By providing the cushioning property only with a paper material, 100
% Renewable and environmentally friendly envelopes.

[0002]

2. Description of the Related Art As shown in FIGS. 5 and 6, for example, a general envelope is formed by bending a sheet-like paperboard by bending a front piece 1 and a back piece 2 from a fold line 3 and bonding the same. Piece 1
The envelopes are formed by gluing the marginal pieces 4 and 5 extending from the left and right sides of each of the valleys along the folding lines 6 and 7 into valleys. In addition, the code | symbol 8 in a figure is a cover piece.

[0003] In the conventional envelope made of only the paperboard or kraft paper, there is no function to protect the stored items by providing cushioning to the stored items. As the one that gives
It is known that an air cushion material formed of a synthetic resin is attached to a bonding surface of the front piece 1 and the back piece 2 made of the paperboard or kraft paper.

However, in the conventional envelope to which the above-mentioned synthetic resin air cushion material is stuck, not only the manufacturing process becomes complicated, but also when recycling, the paper portion and the synthetic resin portion are separated and separated. Since it must be treated, the cost of recycling increases, and in the end, the waste is incinerated without being separated, which poses a problem of environmental pollution.

The present invention has been made in view of the above situation, and an object of the present invention is to provide a core base paper made of 100% embossed waste paper to provide cushioning properties so that the folding direction can be freely changed. Another object of the present invention is to provide an environmentally friendly envelope that can be reproduced at low cost.

[0006]

In order to achieve the above object, according to the present invention, a square-shaped front piece and a back piece are bonded together, and the bonded front and back pieces are combined. The technical premise is that the envelope has a three-sided closed shape and a cover piece extending on one of the open sides of the front piece or the back piece. The laminating surface portion of the piece is formed of a core base paper made of embossed waste paper.

In the present invention, the front and back pieces are specifically bonded to a liner base paper made of kraft pulp and waste paper and a lower surface of a waste paper portion of the liner base paper. And the core base paper.

Further, the present invention is characterized in that a plurality of adjusting broken lines are formed in advance on the lid piece.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to an embodiment shown in the accompanying drawings.

As shown in FIGS. 1 to 3, an envelope F having cushioning performance according to this embodiment is obtained by folding a square-shaped front piece 10 and a back piece 11 at a fold line 12 at a valley line. The bonded front and back pieces 10 and 11
The side pieces 13 and 14 extending on both sides of the
6 are folded in a valley at the boundary and bent and adhered to the front side of the back piece 11 so that three sides are closed and the front piece 1 is closed.
The cover piece 17 is configured to extend from the open side of the “0”.
In the figure, reference numerals 18 and 19 denote decorative broken lines engraved on the front side of the front piece 10 and the back piece 11, respectively.
Numerals 23 denote adjustment broken lines engraved on the cover piece 17, respectively.

The front piece 10, the back piece 11, and the side piece 1
As shown in FIG. 4, the liners 3, 14 and the cover piece 17 are made of a liner base paper 20 in which a kraft pulp 21 and a waste paper 22 are put together, and an emboss E which is spot-bonded to the lower surface of the waste paper 22 constituting the liner base paper 20. And a core base paper 23 made of 100% processed waste paper.

The embossed E formed on the core base paper 23
This pattern is not particularly limited in the present invention. For example, the unevenness can be formed continuously in a substantially cross-shaped orthogonal direction, or the unevenness can be formed continuously in a substantially X-shape.
In this case, for example, in consideration of the shape of the envelope and the folding direction of the lid piece 17, it is desirable to appropriately select and set the row direction and the number of rows and columns, the size, the shape, and the like. In addition, the embossing process used in the conventional cardboard or the like can be applied to the emboss generation step.

As described above, the envelope F having cushioning properties according to this embodiment can be provided with cushioning by the core base paper 23 made of 100% embossed waste paper, and the valley of the embossing E. Since it is possible to bend in any direction along the part, it is easy to seal in accordance with the shape of the stored items,
Since the plurality of fold lines 20, 21, 22, and 23 are engraved on the cover, the lid piece 17 can be bent from a suitable portion in accordance with the thickness of the stored item, and the usability is good. Furthermore, since the embossing E for imparting cushioning properties is formed of the 100% waste paper core base paper 23, low cost can be realized, and furthermore, since the entire envelope F is formed of paper. , Recycling becomes possible.

In the above embodiment, the liner base paper 20
The case where the core base paper 23 embossed is formed by spot bonding has been described by way of example, but the present invention is not limited to this, and is not limited to this. May be formed by spot bonding.

[0015]

As described above, according to the present invention, it is possible to provide cushioning with 100% embossed waste paper core paper and to bend freely along the embossed valleys. As a result, the embossing for imparting cushioning properties is formed of 100% waste paper, so that low cost can be realized. Further, the entire envelope is formed of paper. Therefore, many excellent effects can be obtained, such as providing a recyclable and environmentally friendly envelope.
