Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is an adhesive tape which can be made into a form of a sheet of paper like a postcard by adhering the overlapping surface of a folded document. Regarding

[Background of the invention]

Even if the amount of communication can be sufficiently described only by using the space (description surface) of the postcard, in order to prevent others from seeing the content of the communication document, it is necessary to use a sealed letter for communication. There was no way.

Further, in the case of a correspondence document within the company that requires confidential treatment, it is necessary to make a contact by using a sealed document similar to the sealed mail.

However, when the above method is adopted, it is necessary to prepare an envelope for accommodating this in addition to the document in which the communication items are written, so that it takes a lot of time and effort to address the envelope and seal the opening. However, there is also an economic disadvantage in that a postage charge is required when sending as mail.

[Purpose of device]

The present invention has been made in view of the above circumstances and intends to address this.

That is, the object of the present invention is to conceal the written information of a document by using it on the folded surface of a document that can be folded in two, and the adhesive surface of an adhesive tape attached to the superimposed surface when necessary. It is intended to provide a double-folded document adhesive tape configured so that the items to be described can be easily confirmed by peeling off.

Another object of the present invention is to bond the overlapped surfaces of a folded document so that the overlapped document takes the form of a sheet of paper, which allows postcards to be printed in the postal code. It is intended to provide an adhesive tape for a folded document which can be transmitted as.

[Key points of device]

The present invention polymerizes two transparent synthetic resin films,
This polymerized surface is bonded and integrated with a pseudo adhesive such as paraffin wax, and the outer surface of each of the two polymerized synthetic resin films is made of an adhesive that exerts adhesive force by applying heat. The main point of the invention is the structure of a double-folded document adhesive tape in which the coating surface is integrally formed.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

The adhesive tape A of the present invention comprises two sticking sheets 1,1, a pseudo adhesive 2 for polymerizing and integrating these sticking sheets 1,1 and a thermal adhesive applied on the back surface of the sticking sheets 1,1.
It is composed of 3,3.

The adhesive sheets 1,1 are composed of a transparent and ultrathin synthetic resin film, and the back surface of each sheet 1,1 is a thermal adhesive 3,3 that exerts adhesive force by heating. Is integrally applied.

The adhesive 3 that exerts an adhesive force by heating has a property of not exerting an adhesive force at room temperature,
For example, a wax or polyethylene resin coating film having strong adhesiveness can be used.

The pseudo-adhesive 2 is an adhesive for pseudo-bonding the polymerized surfaces of the patch sheets 1 and 1, and the polymerized surface can be easily peeled off after sticking, and the adhesive does not remain on the bonded surface after peeling. An adhesive having a weak adhesive property, such as paraffin wax, is used.

Reference numeral 4 denotes a document that can be folded in two, and a communication sentence, a communication matter, and the like can be written in the folded inside portion.

[Use of device]

 The present invention constructed as above is used as follows.

(1) Preparation of bi-fold document First, after forming the document 4 in which necessary communication texts, contact information, etc. are foldable, the document 4 is formed on one side of the inner surface when folded in half. Place the adhesive tape A. (See FIG. 2) (2) Next, the remaining one side surface is bent in the direction of the surface on which the adhesive tape A is placed (in the direction shown by the arrow in FIG. 3) to be polymerized, and the form illustrated in FIG. 4 is finished.

(3) In this state, the front and back surfaces of the half-folded document 4 are heated to bond the thermal adhesives 3, 3 applied and formed on both sides of the adhesive tape A to the inner surfaces of the half-folded document 4, respectively. As a result, the folded document 4 has a state of being composed of one sheet, and a document in the form of a postcard according to the Postal Law is obtained. (See FIG. 4) (2) Opening of folded document When the document 4 that has been folded in two by the adhesive force of the adhesive tape A is opened, the overlapping edge of the folded document 4 is removed. If it is peeled off while holding it, the coating layer portion of the pseudo adhesive 2 having a weak adhesive force is peeled off, and the document can be easily opened. In this case, the surface of the document 4 where the communication text, communication items, etc. are described is covered and protected by the adhesive sheets 1, 1 made of a transparent synthetic resin film. (Refer to FIG. 5) [Advantages of the Invention] The effects of the present invention configured as described above are as follows.

(1) If there is a document whose contents you want to keep secret, insert adhesive tape A in the middle of the folded document and then heat from the back of the folded document 4 The thermal adhesive 3,3 applied to the back side is melted and adhered to the inner surface of the folded document 4 so that it can be easily adhered and used. Moreover, by using the adhesive tape A, The content can be kept completely confidential.

(2) On the back surface of the adhesive tape A (the back surface of the adhesive sheet 1, 1), a coating layer of the thermal adhesive 3, 3 that does not exhibit adhesive strength at room temperature is formed, so the surface of the thermal adhesive 3, 3 It is not necessary to cover the part with a release paper or other surface protective material, and the economical effect can be achieved in terms of manufacturing cost.

Further, since there is no material to be peeled off, there is an advantage that when the adhesive tape A is used, a peeled-off separator or the like is not generated and the work site is not polluted.

(3) Since the double-folded document 4 adhered and integrated with the adhesive tape A is completely in the form of a single sheet in appearance, it may be handled as a postcard when it is sent as a mail item. It is possible to eliminate the complexity of sealing in the case of forming a postal item with a sealed letter and the economic disadvantage of the sealed letter with a postal item.

(4) When the adhesive tape A is used to open the document 4 which is folded and closed in half, since the intermediate portion of the two adhesive sheets 1 and 1 is adhered by the application layer of the pseudo adhesive 2 having weak adhesive force. If you peel off the adhesive edge of the document 4 (especially the edge of the overlapping surface) to open on both sides, the two adhesive sheets 1,
The pseudo adhesive 2 existing in the intermediate portion of 1 can be easily peeled off from the coating layer portion to open the package.

In addition, since the adhesive layer of the pseudo adhesive 2 has a weak adhesive force, it is impossible to re-adhere a document that has been opened. Therefore, if the document is opened by another person, the trace of the opening can be easily made. There are features that can be confirmed.

(5) The structure is simple and it can be used at low cost.
