Description

Description: TECHNICAL FIELD The present invention relates to sanitary paper such as tissue paper, dust paper, toilet paper, and towel paper used by wiping or wiping a body or object.

(Prior Art) The present applicant has filed Japanese Patent Application No. 63-159261 (JP-A-2-104317).
No.), two embossed papers having the same concavo-convex pattern are adhered to each other with the convex parts of the pattern facing each other, and various powders for sweating, deodorizing, etc. in the space between the concave parts of the opposing pattern, A sanitary paper containing microcapsules containing liquids such as disinfectants, deodorants, fragrances, and fragrances was proposed.

(Problems to be Solved by the Invention) In the above-mentioned sanitary paper, the protruding portions that protrude from the front and back of the paper surface of the concave portion of the opposing pattern are in an embossed state, so that the paper is thick and bulky. Compared to paper that remains flat, for example, toilet paper has a water retention about 17 times as large as that of toilet paper, and when used by wiping or wiping it used to require a large area, but the same amount of water was used. Although it has the advantage of being able to retain water in a small area and saving the amount of use, it is very thick and bulky, so if it is wound up in a roll, the diameter of the roll will increase, and if it is folded and stacked, the height will increase .

(Means for Solving the Problems) Therefore, the present invention does not reduce the water retention, and yet prevents the diameter when wound up in a roll from increasing or the height when folded and stacked. The two embossed papers with the same concavo-convex pattern are adhered to each other with the protruding parts of the pattern facing each other, and the protruding parts protruding from the front and back of the paper surface of the concavity of the opposing pattern are designed. It is characterized in that the protrusion amount is reduced by crushing.

(Example) In the illustrated example, A and B are embossed paper in which the same convex portion 1 and concave portion 2 having the same size and arrangement are extruded from the paper surface to form a concavo-convex pattern. One sheet is adhered to each other with a starch-based or other suitable adhesive 3 to form a base sheet of two sheets of tissue paper, dust paper, toilet paper, towel paper and the like.

In order to actually manufacture this base paper, two sheets of embossed paper A and B having the same wide width are fed out, for example, one is placed on the upper side and the other is placed on the lower side. Is sprayed, and the convex portions 1 and 1 of the upper embossed paper and the lower embossed paper face each other, and are wound while being bonded with an adhesive. Then, the base paper is rolled into a required narrow width to form a toilet paper or a towel paper, or cut into a required size, and folded into a tissue paper, or bundled into a dust paper.

Now, according to the present invention, the protruding portions projecting from the front and back of the concave portions 2 and 2 of the pattern facing each other are crushed to reduce the protruding amount. In the drawings, the projection before being crushed is shown by a broken line, and the projection in the crushed state is shown by a solid line.

The process of crushing the protruding portion may be performed before winding the base paper, that is, when bonding the upper and lower embossed paper with the convex portions facing each other with an adhesive or after bonding, or in the state of the base paper without crushing. When processing into a product such as toilet paper, it may be crushed. This crushing can be performed by passing the paper between two rolls or a plate or the like with a required interval.

Also, the degree of crushing to reduce the amount of protrusion of the protruding portion is determined by the interval between the rolls and plates, etc., but when passing through the interval, it is completely crushed, but after passing, it was embossed by embossing The projecting force is restored to a certain extent by the restoring force, and in consideration of this, for example, the projecting amount is reduced by about half, about 2/3, or appropriately according to the paper quality. You only have to decide.

As described above, the sanitary paper according to the present invention projects two identical embossed papers on the front and back sides of the opposing concave portion to be soft, because the two embossed papers are adhered and polymerized by bonding the convex portions. Although the protrusion amount of the protrusion is reduced, there is a sense of thickness. Further, when water is absorbed into the space between the opposed concave portions 2 and 2 and the water is absorbed, the crushed concave portion is almost restored to its original state and protrudes, so that the water retention is almost the same as the original state where it is not crushed. high.

A space 4 between the opposed concave portions 2 and 2 contains microcapsules 5 containing liquids such as various powders for sweat removal and deodorization, and disinfectants, deodorants, fragrances, and fragrances. You may. When the microcapsules 5 are accommodated in the space 4 opposed to the recesses 2 and 2, if the pair of rolls for crushing the protruding portions protruding from the front and back of the paper and the interval between the plates are set to 0,
As all the contained microcapsules break and become useless, even if some microcapsules are damaged,
The interval is appropriately determined so that the remaining microcapsules are not crushed.

(Effects of the Invention) According to the present invention, the touch feeling is soft, the water retention is excellent, but the thickness is not bulky, and flat paper is rolled,
It is possible to provide a product that is not much different from a product that is folded, stacked, or bundled.

[Brief description of the drawings]

The drawing is an enlarged sectional view showing one embodiment of the present invention.
And B are embossed papers obtained by processing the same pattern, 1 is a convex portion of the concavo-convex pattern, 2 is a concave portion, and 3 is an adhesive.

Claims (1)

(57) [Claims] An embossed paper sheet having the same concavo-convex pattern is adhered to and opposed to each other by the convex portions of the pattern, and the protruding portions protruding from the front and back sides of the paper surface of the concave portion of the opposing pattern are crushed. Sanitary paper characterized in that the amount of water is reduced.
