Are bonded by an adhesive 10.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to envelopes such as envelopes and medicine bags, and more particularly to envelopes with reduced bulkiness.

[0002]

[Prior art]

 For example, in the case of envelopes such as medicine bags, prescription indications and the like are printed on individual patients by a printer such as a personal computer.In this case, the feed rate of the pinch roller is increased due to the large bulk of the margin for ordinary envelopes. There is a problem that the paper may fluctuate between the left and right, and especially in a magazine type inserter, it is difficult to feed the printer smoothly as with ordinary paper.

[0003] Therefore, there is also an envelope that eliminates the bulk unevenness due to the above-mentioned adhesive margin and allows a fixed amount to be inserted into a paper feed magazine of a printer. Conventionally, such an envelope is created by gluing two sheets of paper that are superimposed on each other in a three- or four-sided manner. The use of two sheets of paper requires two printing plates and two printings, which causes a problem that the production cost is higher than that of the ordinary envelope.

[0004]

[Problems to be solved by the invention]

 The present invention addresses the situation described above, folds one sheet of paper into two, and glues the area around it to reduce the unevenness of the envelope and facilitate the paper feeding to the printer. At the same time, it is intended to reduce costs by performing double-sided printing with one plate and one printing.

[0005]

[Means for Solving the Problems]

 That is, the envelope of the present invention that meets the above-mentioned object is an envelope in which paper is folded almost in two to form a bag. One of the two folded pieces is longer than the other, and the paper is folded in two. Then, the tip of the long folded piece is folded back and abutted against the tip of the short folded piece, and the inside of each of the folded portion and the folded portion and the mating portion on both sides of the folded piece are bonded with an adhesive. It is characterized by having done. When a hot-melt adhesive is used, the adhesive is applied in advance, and after the folding step, bonding is performed by a hot press or the like.

[0006]

[Action]

 In the envelope of the present invention, since the adhesive is applied and the paper is adhered all around, the unevenness of the envelope is reduced in these four rounds, thereby making it possible to feed the paper to the printer smoothly. is there. Since the envelope is formed by folding one sheet of paper, if it is necessary to print on the front and back of the envelope in advance, printing is performed before folding the paper, so that printing can be performed at a low cost with one printing and one printing. It is possible to do.

[0007]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing the glued state of the envelope according to the embodiment of the present invention viewed from the back, FIG. 2 is a developed view showing the inside of the envelope, FIG. 3 is a developed view showing the same and the outside, and FIG. FIG. 5 is a back view of the same envelope.

In the envelope of the above embodiment, as shown in FIGS. 1 to 3, the paper 1 is folded in two at the fold line 2 to substantially form the outer shape of the rectangular bag. In this case, the paper 1 is folded in two by making one of the two folds 3 from the fold 2 longer than the other 4, and the leading end 3a of the longer two folds 3 is folded back at the fold 5, Abutting against the distal end portion 4a of the shorter two-folded piece 4, and heat is applied to the inside of each of the two-folded part 6 and the folded-back part 7 and the mating parts 8 and 9 on both sides of the two-folded pieces 3 and 4, respectively. A pressure bonding adhesive 10 (vinyl acetate heat seal adhesive) is applied and adhered.

As shown in FIG. 5, the opening 11 of the envelope is formed at the butting portion of the long and short two-fold pieces 3 and 4 on the back surface of the envelope. In this embodiment, the pair of two-fold pieces 3 , 4 are facing each other without overlapping. The thermocompression bonding adhesive 10 is liquid at room temperature, applied on both sides of the bonded portion of the envelope, dried, and then bonded by polymerizing and thermocompressing both surfaces of the bonded portion.

On the other hand, FIG. 6 is a side view showing an apparatus for manufacturing the envelope of the above embodiment. The paper 1 pulled out from the winding base paper 12 is printed by a printing unit 13 and is subjected to a UV dryer 14. After that, the paste is once dried by the high frequency dryer 16 and then folded by the folding machine 17 as described above, and the glue is bonded by the thermocompression bonding machine 18. Then, the sheet is cut by the cutting unit 19 and sent to the sheet discharging unit 20 as a product. As shown in FIG. 7, in the folding machine 17, the folding machine 17 is continuously folded in the longitudinal direction of the paper 1 around the fold line 2 and the fold line 5 around the width mold 21. Done.

The folded paper 1 is sent to the next thermocompression bonding machine in the form of a cylinder as shown in the figure, where it is subjected to hot pressing to bond the applied hot-press adhesive 10. Let it. Since the adhesive is applied to the necessary places in units of envelopes as described above, the bonding of the envelopes is completed at this time, and thereafter, the envelopes are cut into the size of the envelopes to obtain the final product.

However, in the envelope according to the embodiment of the present invention, since the adhesive is applied to the entire periphery and the paper is adhered to the envelope, the unevenness of the envelope is reduced in the four periphery, thereby supplying the envelope to the printer. The envelope can be formed by folding one sheet of paper, and the envelope can be formed smoothly by folding one sheet of paper. Printing can be performed at a cost.

[0014]

[Effect of the invention]

 As described above, the envelope of the present invention is an envelope that is formed by folding paper into almost two pieces to form a bag body. One of the two folded pieces is longer than the other, and the paper is folded into two pieces. The tip of the long fold is folded back and butted against the tip of the short fold, and the inside of each of the two folds and the fold is bonded to the joining portion on both sides of the two fold. Yes, the adhesive is applied and the paper is adhered on the entire circumference of the envelope, so that the unevenness of the envelope is reduced on these four circumferences, so that the paper can be smoothly fed to the printer and one envelope is used. Because it is formed by folding paper, even if it is printed on the front and back in advance, it can be printed at a low cost by printing one plate per plate by applying this paper before folding, thereby producing an envelope at low cost. And the remarkable effect of It is intended to.
