Abstract

PROBLEM TO BE SOLVED: To provide a web of stacked layers in which the full width of the web of the stacked layers is not increased, the overlap width the left web and right web of the web of the stacked layers is made proper, and also the number of folding times are formed per unit during production is reduced. SOLUTION: In a web 1 of layer stacked in which left webs 2 and right webs 3 are stacked one layer upon the other layer while being mutually interfolded, the ends of the left webs 2 are brought into contact with or close to each other, and the ends of the right webs 3 are brought into contact with or close to each other. Also, with each of left webs 2 and each of the right webs 3 overlapped successively by half the length and with each two sheets kept overlapping, they are alternately folded zigzag in the position of half the width of each overlap, thereby forming a stack of layers, and thus the number of times that folds are formed per unit during production is reduced.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated web formed by laminating a plurality of webs such as wet tissue and dry tissue, and a laminated web package containing the laminated web in a container.

[0002]

2. Description of the Related Art A web such as a wet tissue or a dry tissue, for example,
It is manufactured in the state of a laminated web which is laminated in a state where it is folded into the mating web from each side from the left and right sides. This type of laminated web is stored in a container and used in the form of a laminated web package. In this laminated web package, every time one web is pulled out from the outlet of the container, a part of the next web comes out of the outlet due to the frictional force between the webs. By pinching the portion, the next web can be pulled out.

[0003] By the way, as shown in Figs. 4 to 10, there have been known heretofore, as this kind of folded laminated structure of a laminated web. First laminated example in FIG. 4 A laminated web 1 in a laminated web package shown in FIG. 4 has a left web 2 and a right web 3 folded in half in a length of 1/2 and mutually folded into the mating web to the full depth. Not.
In this case, the overlap width Wa of the left web 2 and the right web 3
Is approximately 1/2 of the original web length.

Accordingly, in the laminated web package shown in FIG. 4, the overlap width Wa of the webs 2 and 3 on the left and right sides is large (approximately 1/2 of the original web length), and the container 1 is pulled out when the web is pulled out.
The next web exiting portion 3a coming out from the outlet 11 of 0 is long (for example, about 1/2 to 1/3 of the original web length), and the appearance is impaired. Further, in the case of a wet tissue, the friction between the webs is large, so that the left web 2
When the overlapping length (overlapping area) between the web and the right web 3 becomes large, the whole web in the next order may be pulled out when the web is pulled out. Second conventional example of FIG. 5 The laminated web 1 in the laminated web package shown in FIG. 5 has the webs 2 and 3 on the right and left sides folded into three in an S-shape, respectively, and is mutually folded into the mating webs. . in this case,
The overlap width Wb of the left web 2 and the right web 3 is approximately / of the original web length.

The web overlap width Wb in the case of FIG. 5 is slightly smaller than the overlap width Wa of the laminated web 1 in FIG. 4, but still about 1/3 of the original web length is overlapped. The web projecting portion 2a projecting from the container outlet 11 becomes considerably long (deteriorating the aesthetic appearance), and in the case of a wet tissue, the next web may be pulled out with it. FIG. 6 shows a third conventional example . In the laminated web 1 in the laminated web package shown in FIG. 6, as shown in FIG. 6A, the left web 2 and the right web 3 have a small length at the center of the laminated web 1. Range (overlap width W
Only c) is polymerized.

However, in the case of FIG. 6, the overlapping width W
Since c is small, the next web projection 2a is small, but the number of webs to be laminated is larger at the center of the laminated web 1 (range of the overlapping width Wc) than at both sides thereof, and FIG.
As shown in (B), the laminated web 1 becomes partially bulky (in this case, the central portion becomes bulky). As described above, when the laminated web 1 becomes partially bulky, the posture becomes unstable at the time of manufacturing the laminated web 1 and the height of the laminated web 1 increases in proportion to the number of webs, so that the accommodation in the container 10 is performed. The amount is reduced. 7A and 7B, in the laminated web 1 in the laminated web package shown in FIG. 7, as shown in FIG. 7A, the left web 2 and the right web 3 are combined in a predetermined range (overlapping) on one side of the laminated web 1. Range of width Wd)
Are polymerized.

Accordingly, in the case of FIG. 7, since the overlapping portions of the webs 2 and 3 on the left and right sides are offset to one side,
As shown in (B), the shape of the laminated web 1 is deformed (partially bulky), and the accommodation amount in the container 10 is reduced. Fifth conventional example of FIG. 8 In the laminated web 1 in the laminated web package shown in FIG. 8, the webs 2 and 3 on the left and right sides are each separated by 2/3 at a 1/3 length position.
In a folded state, they are folded into each other's web.

In the case of FIG. 8, the overlapping width We of the left web 2 and the right web 3 (which can be formed at two places on the left and right) is substantially 1/3 of the original web length, and the next web projection portion is provided. 2a
Becomes considerably long, and the total width L of the laminated web 1 becomes 2/3 of the original web length, so that the container 10 becomes large (the occupied floor area of the laminated web package increases). 9 and FIG. 10 show a conventional example shown in FIG. 9 of Japanese Patent Application Laid-Open No. 7-213453, in which a laminated web 1 in a laminated web package includes webs 2 and 3 on the left and right sides. At its center (signs b,
In d), the web is folded in two, and each of the folded pieces is further folded in two, and the webs are mutually folded into the mating webs. Therefore, the overlap width Wf (at two locations on the left and right) of the left web 2 and the right web 3 is approximately ４ of the original web length, and is in an appropriate range.

FIG. 10 shows a method of folding the left and right webs 2, 3 of the laminated web 1 of FIG.
In the laminated web 1 of this conventional example, the symbols a to
d, it is necessary to fold at four places, and the number of times of folding per unit increases during the production of the laminated web 1,
The configuration of the folding device becomes complicated (the number of folded portions increases).

As described above, the first to sixth conventional examples have advantages and disadvantages, and cannot satisfy all of them.

In view of the above circumstances, the present invention does not increase the total width of the laminated web (1/2 of the original web length), and adjusts the overlapping width of the left web and the right web in the laminated web to an appropriate value (the original width). It is a first object of the present invention to provide a laminated web whose web length can be reduced to approximately 1/4) and the number of times of folding per unit can be reduced (2 times) during manufacturing. A second object is to provide a laminated web package containing a laminated web.

[0012]

The present invention has the following structure as means for solving the above-mentioned problems. The invention according to claim 1 of the present invention is obtained by laminating webs on the left and right sides in a state where the left web and the right web are overlapped by a predetermined length and folded into the mating webs. It is intended for laminated webs.

In the laminated web according to the present invention, the web ends of the left webs and the web ends of the right webs are respectively joined or brought close to each other, and the left web and the right web are approximately 1/1 mutually. In a state of being polymerized by two lengths, the positions of 1/2 of the widths of the respective superposed parts are alternately folded in a zigzag shape while being superposed two by two.

According to the first aspect of the present invention, the laminated web has the same bulkiness over its entire width (there is no partial bulky portion),
In addition, the entire width is の of the original web length, and it is compact. In addition, in this laminated web, the number of times of folding per unit may be two times, so that the number of times of folding is reduced during the production of the laminated web and the structure of the folding device is simplified (only a small number of folded plates is required).

The laminated web is commercialized in a state of being stored in a packaging bag, and is used, for example, in a refillable container. In this laminated web, the left web and the right web are positioned at a half position (1/2) of the overlap width (1/2 length).
(4 lengths), so that when the uppermost web is pulled out from the outlet, a part of the next-order web comes out from the outlet. When the laminated web is a wet tissue, the frictional force between the web to be drawn and the next web becomes strong. However, in the laminated web of the present application, the range in which the frictional force is generated when the web is drawn is the original web length. 1 /
4, the next web extension length is 1/4 or less of the original web length (actually, 1/6 to 1/1 of the original web length).
8) and the appearance does not worsen. The invention of claim 2 of the present application is directed to a laminated web package in which the laminated web of claim 1 is housed in a container having an outlet formed on the upper surface.

In the laminated web package according to the second aspect, the uppermost web is pulled out from the outlet of the container so that a part of the web located in the next order comes out from the outlet.

In the laminated web package according to the second aspect, since the total width of the laminated web is 1/2 of the original web length, the container is not so large, and when the web is pulled out from the outlet, the following is required. The length of the web in the order coming out of the outlet is not so long.
