Abstract

The present invention provides a lightweight paper cushion envelope that does not require a sorting operation at the time of disposal and is easy to use and easy to use.
SOLUTION: A ruled line 5 is formed on the inner surface of a paper envelope 1 having a tongue 2 at a right angle with respect to a stepped mountain and further oblique, and the stepped mountain is folded inward with a ruled line 10 for half-folding. By crushing the single-sided corrugated cardboard sheet 4 at both end portions 9 and adhering it to the envelope opening edges 7 and 8, there is no need for separation work at the time of disposal, and an easy-to-use paper buffer envelope that is easy to enclose Can be provided.

Description

Detailed description of the invention

The present invention is a single-sided corrugated cardboard that does not require separation work in the case of incineration, as well as in the case of disposal after disposal, in a buffer envelope having a buffer material inside a paper envelope. The present invention relates to a buffer envelope having a sheet.

Various types of buffer envelopes have been devised and put into practical use. For example, a plastic foam sheet used as a cushioning material is required to be separated at the time of disposal. Moreover, it is the end user who actually performs the sorting work, and how to ask the manufacturer's responsibility for it is a big social problem.

An object of the present invention is to provide a lightweight paper cushion envelope that does not require a sorting operation at the time of disposal and is easy to use and easy to use.

The light-weight paper shock-absorbing envelope of the present invention that achieves the above object and does not require sorting and disposal is the same as that of the paper envelope 1 having the tongue 2 as shown in FIGS. 1, 2, 3, and 4. The inner surface is provided with a ruled line 5 that is perpendicular to the stepped mountain at a right angle and further inclined, and both ends of the single-sided corrugated cardboard sheet 4 half-folded with the half-folded ruled line 10 facing the stepped mountain toward the stepped mountain as shown by the portion 9 Is crushed and adhered to the envelope opening edges (7, 8). The ruled line here is a common name in the industry and indicates a groove.

The following effects are produced by the present invention.
(1) Since it is composed only of a single-sided cardboard sheet and a paper envelope, separation at the time of disposal is unnecessary, and weight reduction can be achieved.
(2) Since both ends of the envelope opening edge (7, 8) and the single-sided cardboard sheet 4 are adhered, the inclusion is not easily caught on the single-sided cardboard sheet edge, and packing and sealing work is easy and convenient.
(3) Since the both sides of the single-sided corrugated cardboard sheet 4 are crushed as shown by the portion 9, the inclusions are not easily caught on the edge of the single-sided cardboard sheet, and packing and enclosing operations are easy and convenient.
(4) Since the ruled line 5 which is perpendicular to the stepped mountain of the single-sided corrugated cardboard sheet 4 is further inclined, flexibility is produced on the inner surface of the envelope, and it is easy to fit the inclusion.

The light-weight paper shock-absorbing envelope of the present invention that achieves the above object and does not require sorting and disposal is the same as that of the paper envelope 1 having the tongue 2 as shown in FIGS. 1, 2, 3, and 4. The inner surface is provided with a ruled line 5 which is perpendicular to the stepped mountain at a right angle and further inclined, and the both ends of the single-sided corrugated cardboard sheet 4 which is half-folded by the half-folded ruled line 10 with the stepped mountain facing inwardly are stepped like portions 9. The pile is crushed and adhered to the envelope opening edge (7, 8). Further, in order to increase the production efficiency, as shown in FIG. 4, in the unfolded state of the single-sided corrugated cardboard sheet 4, the half-fold ruled line 10 and the ruled line 5 and the part 9 which are further inclined at right angles to the stepped mountain. What is necessary is just to process all of the crushing of the step mountain and the adhesive application. In order to simplify the sealing operation, it is more preferable to use an envelope in which a double-sided tape or an adhesive 3 is attached to the tongue 2. Further, by using 70% or more of recycled paper as a paper envelope base paper, coupled with the use of single-sided cardboard sheets, it contributes to environmental protection such as resource saving and can contribute to society.

It is a perspective view of the present invention. It is sectional drawing of an envelope side surface. It is sectional drawing of an envelope bottom face. It is a development perspective view of a single-sided cardboard sheet.

Claims (2)

On the inner surface of the paper envelope 1 having the tongue 2, the single-sided corrugated cardboard sheet 4 is half-folded with a half-fold ruled line 10 with the corrugated mountain facing inward, and both ends 9 are adhered to the envelope opening edges (7, 8). Paper cushioning envelope characterized by that. 2. The paper cushion envelope according to claim 1, wherein a stepped portion of both ends 9 of the single-sided corrugated cardboard sheet 4 is crushed, and a ruled line 5 that is perpendicular to the stepped mountain and further inclined is applied.
