Description

[Detailed Description of Device] a. TECHNICAL FIELD The present invention relates to an envelope for sending articles.

In particular, the present invention relates to an article-sending envelope made of a plastic film that can be used for postal purposes in which an article is entrusted to a third party and sent.

B. 2. Description of the Related Art When an envelope made of a plastic film is used for sending an article, the plastic film is superior to a paper envelope in that it is hard to tear and has water resistance. However, compared with paper, it is weaker and very thin, so its protection function against impact and bending is inferior.

In addition, when an article is put in an envelope and sent by mail or the like, there are often two methods.

When the article is something which is unfavorable to be bent like a floppy disk or a document, a cardboard is attached to the article on both sides or one side of the article, and the article is put in an envelope for encapsulation.

Further, when the article is disliked to be scratched, the article is wrapped in a cushioning sheet or the like and then enclosed.

In either case, it takes a lot of time to take measures to protect the articles.

On the other hand, envelopes for mail and the like are required to keep the content confidential, and the address, sender's name, etc. are written on the envelope and used.

However, unlike paper, the surface of plastic film is very smooth, so it is difficult to write on it, and even if you peel off the opening, no trace of it remains, so the reliability of the seal cannot be guaranteed. There are drawbacks. In order to use a plastic film envelope for a mail envelope or the like, it is usually required to have both the functions of guarantee of sealing and good writability at the same time.

The present inventor first devised a method for identifying the opening of a plastic film envelope, which was registered as Utility Model Registration No. 1406838 (Jitsuko Sho 56-96).
No. 41).

The present inventor has also proposed in the previous application that the matte ink is applied onto the plastic film of the envelope to improve the writability.

C. DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention is intended to provide a function of protecting an encapsulated article when a plastic film envelope is used for sending an article or the like.

D. Means for Solving the Problems The present invention is a half-fold polymerization of a multilayer body in which a thermoplastic cushioning sheet is sandwiched between two thermoplastic films, and the folded portion is used as the bag bottom portion and the upper opening portion is formed. Is a bag opening, and the inside of the opposite thermoplastic films is the article delivery part, and the side edges of the polymerized bag are cut by fusion and fusion. The above-mentioned problem is solved by an article-sending envelope characterized in that sheets are integrally fused and fixed.

E. Embodiments The present invention will be described in detail with reference to embodiments. 1 and 2 show the most typical embodiment of the present invention.

The envelope of this embodiment comprises a front surface portion 1, a rear surface portion 2 and a sealing film 9, and both the front surface portion 1 and the rear surface portion 2 are formed by two thin plastic films 3, 4, 5 and 6. These four films are fused at the side edges 12 and 13 of the envelope. The upper portions of these films are opened, and an opening of an envelope for inserting an article is provided between the films 4 and 6, and buffer sheets 7 and 8 are housed on both sides of the openings.

Various types of cushioning sheets can be used in the present invention depending on the articles to be enclosed. For example, a hard synthetic paper, a plastic sheet or a hard foamed plastic sheet can be preferably used for an article such as a floppy disk.

Further, a sheet having a well-known cushioning property such as a soft resin sheet or a soft foam sheet can be preferably used for a material such as a calculator or a video cassette which is not sensitive to impact.

According to the present invention, when the material of the cushioning sheet is made of thermoplastic, it is put between two thin plastic films from the beginning in the bag structure, and when the side edge of the envelope is fused, it is cut at the same time. There is a feature in doing it. At this time, the buffer sheet is fixed to the side edge portion of the envelope.

The front surface portion 1 is bent at the bottom portion 14 and is continuous with the back surface portion 2. A sealing film 9 is continuously provided on the film 3 above the surface portion 1. The sealing film 9 is provided with an adhesive layer 10 having an opening discrimination capability.
The peeling tape 11 is stuck on it.

The adhesive layer 9 having the unsealing discrimination ability is printed with a graphic or a character inside, and the peeling tape 10 on the adhesive layer 9 is peeled off to once seal the opening, and then the adhesive is removed when the seal is peeled off. Since the layer 9 is separated on both sides of the adhesive surface, the internal figure and the like are destroyed, and it is impossible to restore it again. For example, the method proposed by Utility Model Registration No. 1406838 devised by the present inventor is particularly suitable.

As the adhesive layer 9 having the opening identifying ability that can be used in the present invention, any adhesive layer 9 can be used as long as the figure or the like is contained in advance and the figure or the like has a structure to be destroyed at the time of opening. it can.

The position on the front surface or the back surface of the envelope of this embodiment where the address and the sender's address are written is the mat ink coating layer in advance.
15 is applied.

Matt ink is usually applied on the surface for matting, for example, XOX-120 manufactured by Dainippon Ink and Chemicals, Inc.
6 is used in this embodiment.

The matte ink coating layer 15 can be applied to the entire surface of the envelope film. In this case, since the position of the stamp is also applied, the stamp can be easily attached, and the adhesion of the seal at the opening and the identification of the opening can be surely confirmed.

Also in this embodiment, the matte ink is applied not only at the address of the front film and the position of the postal code, but also at the position where the sender address of the back film 2 is written, as well as the position where the stamp is applied and the adhesive which has the opening identifying ability. It is also provided at the position where the layer 9 is bonded. This makes it easier to stick the stamp, and the sticked stamp becomes less likely to peel off, and since the adhesion of the seal becomes strong, partial transfer of the opening identification adhesive layer 10 to the adhesive facing surface when peeling this Definitely done. For this reason, the breakage of the figure or the like inside this can be clearly detected, and the opening can be identified more reliably.

When sending articles such as documents that simply do not want to be bent, it is sufficient to insert only one buffer sheet and a hard sheet.

F. Effect Although the envelope for sending articles of the present invention is made of plastic film, it has an excellent function of protecting the articles enclosed therein,
Further, since it can be made to have an opening identification ability and a good writing ability, it is particularly useful for transporting, delivering or consigning articles such as merchandise.

In addition, the envelope of the present invention has the advantage that efficient production can be achieved by manufacturing it in a continuous bag-making process.
