Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a communication sheet used as a regular or non-standard size mail, such as a postcard, and more specifically, a plurality of communication sheets having a size of a standard postcard. The present invention relates to a communication sheet (which is referred to as a "folded communication sheet" throughout this specification) in which sheets are folded and brought into close contact with each other so that a recipient can peel off the sheets.

[Problems of the prior art and device] Conventionally, as a folded communication sheet, it is composed of a sheet material divided into left and right leaves through a center fold line, and an adhesive layer applied on the upper surface of the sheet material. Is known to be able to peel off the left and right two leaves as desired by folding along a fold line so as to match the adhesive layers (see Japanese Utility Model Publication No. 1-145473).

In the above-mentioned conventional folded communication sheet, the adhesive is applied after printing or printing is performed on the upper surface of one of the left and right sheet materials, but the adhesive is applied every time printing or printing is performed. Applying was a tedious task.

Therefore, if the heat fusion adhesive is applied first and the two leaves on the left and right are adhered by heating and pressing after printing or printing, the heating and pressing work is
Since it is extremely simple as compared with the adhesive application work, it can be easily performed each time printing or printing is performed, which is very convenient.

However, in order to print or print after applying the adhesive first, it is easy to print or print on the surface of the adhesive layer, the left and right two leaves that are bonded are easily separated, and the left and right bonded It is necessary to prevent printing or blocking of printing due to peeling of the two leaves. Heretofore, an adhesive that satisfies all of these has not been known.

In view of the above situation, the present invention is capable of easily printing or printing on the surface of the adhesive layer, and easily peeling off the left and right adhered two leaves without blocking of printing or printing accompanying the peeling. It is intended to provide a communication sheet that can be used.

[Means for Solving the Problems] In order to achieve the above object, the folded communication sheet according to the present invention is a sheet material (4) divided into left and right lobes (2) and (3) through a central folding line (1). And an adhesive layer applied on the top surface of the sheet material (4)
The left and right two leaves (2) and (3) are folded and adhered by the broken line (1) so that the adhesive layer (5) is aligned, and the left and right two leaves (2) and (3)
In the folded communication sheet that can be peeled off as desired, the adhesive layer (5) is composed of a heat-fusion adhesive mixed in a state where a release agent is contained in microcapsules. The surface of (5) is characterized by being printed or printed (6).

The sheet material (4) is usually made of paper, and the upper surface thereof, that is, the folding surface is not printed or printed. The sender's address, name, etc. are printed on the outer surface of either one of the left and right two leaves (2) and (3).

The adhesive for the heat-fusion adhesive layer (5) is not particularly limited, but an aqueous or solvent solution type acrylic adhesive is often used. The release agent contained in the heat-fusion adhesive is not particularly limited, and for example, paraffin wax,
Wax-based releasing agents such as carnauba wax and silicone wax are preferably used. Printing and printing of the heat-fusion-type adhesive layer (5) are performed by a usual method using a printer or a copying machine. By mixing the release agent contained in the microcapsules, the heat-sealing adhesive layer (5) is easily printed or printed on the surface, and further, the printing or printing (6) is blocked by peeling. The left and right two leaves (2) and (3) that have been adhered can be peeled off without rubbing.

Left and right lobes (2) (3) of sheet material (4) with heat-sealing adhesive layer (5)
Are bonded by folding the left and right two leaves (2) and (3) and then heating and pressing the folded product.

[Operation] According to the folded communication sheet of the present invention, since the release agent is mixed in the heat-sealing adhesive while being encapsulated in the microcapsules, it is easy to print or print on the surface, Moreover, the left and right two leaves (2) and (3) adhered to each other can be easily peeled off without causing blocking of printing or printing (6) accompanying the peeling.

[Embodiment] Next, the present invention will be specifically described with reference to the illustrated embodiment.

FIG. 1 shows a state before the folding communication sheet according to the present invention is folded. In the figure, the sheet before folding is a paper sheet material (4) divided into left and right leaves (2) and (3) through a center fold line (1), and an upper surface of the sheet material (4). And a heat-fusion-type adhesive layer (5) coated on and containing a release agent. A solvent solution type acrylic adhesive is used as the heat-fusion adhesive, and paraffin wax contained in microcapsules is used as the release agent. A printer prints on the surface of the adhesive layer (5) (6)
Has been applied. Although the release agent has poor ink adhesion, it is printed because it is contained in microcapsules.
It does not hinder (6).

The left and right lobes (2) (3) of the sheet material (4) are folded along the fold line (1) so that the adhesive layer (5) is aligned, and then the left and right lobes (2) by heating and pressing the folded product. (3) are glued together (see Figure 2). Along with the collapse of the microcapsules, the release material is eluted into the heat-sealing adhesive and exhibits its original function as a release agent.

As shown in FIG. 3, the folding communication sheet thus constructed has two leaves on the left and right sides without causing printing or printing (6) blocking due to peeling at the mail recipient.
(2) (3) can be peeled off.

[Effect of Invention] As a result of the above, the folded communication sheet according to the present invention is
Since the adhesive layer (5) is composed of a heat-fusion adhesive in which the release agent is mixed in a state of being encapsulated in the microcapsules, it is easy to print or print on the surface of the adhesive layer (5), and It is possible to easily peel off the left and right two leaves (2) and (3) that are adhered to each other without causing blocking of printing or printing (6) accompanying peeling.
