Description

  The present invention relates to a wet tissue superimposed body and a wet tissue package.

  A wet tissue in which a web is impregnated with a chemical solution is useful for wiping off dirt, but it is necessary to maintain the wet state as much as possible until it is used. Therefore, the wet tissue is folded, and a plurality of the folded wet tissues are overlapped to form a superposed body, and the superposed body is accommodated in a container such as a container or a bag.

  A so-called pop-up method is known as a method of taking out a web forming a wet tissue from a wet tissue package in which such a wet tissue is stored in a container. In the pop-up method, when the upper web is taken out, a part of the next web adjacent on the lower side is projected from the outlet, and the web constituting the wet tissue is easily taken out. In this method, the wet tissue webs stacked one above the other are stacked while forming a configuration (overlap part) in which a part of the lower web is arranged on a part of the upper web, It is formed.

  As a wet tissue superposed body employed in the pop-up method, specifically, a wet tissue superposed body (superimposed body A) having a configuration as shown in FIG. 5 has been conventionally known. The superimposed body A is formed as follows. Between the positions 101 and 101 that divide the web 100 constituting the wet tissue into three equal parts and the two positions 102 and 102 that are further away from the center of the web 100 among the positions that divide the web 100 into four equal parts. Folded portions 103 and 103 are formed, and the portions from the left and right ends of the web 100 to the bent portions 103 and 103 are folded back to the opposite surfaces to form a web folded body 104 having a longitudinal section Z shape. The web folded bodies 104 and 104 are aligned so that the central portions 105 and 105 overlap in the vertical direction, and a part of the lower portion 106 of the web folded body 104 and the upper portion of the web folded body 104 are aligned. Overlap portion 109 is formed by sequentially overlapping so that a part of 107 overlaps. At this time, a part on the upper surface side of the lower part 106 of the upper web folded body 104 and a part on the lower surface side of the upper part 107 of the lower web folded body 104 are made to face each other.

  Here, at the time of manufacturing the wet tissue package, the wet tissue superposed body is usually used so that the structure of the wet tissue superposed body is not broken and the webs are not separated from each other. Is moderately pressed in the vertical direction. In particular, wet tissue is usually impregnated with a chemical solution before the pressing load is applied, and an appropriate pressure is applied to uniformly impregnate the entire wet tissue superposed body with the chemical solution.

  However, in the conventional superposed body A as described above, the overlap portion 109 is formed, so that the central portion is formed more bulky than the both end portions of the superposed body A, and the thickness is not uniform. For this reason, even if it is going to apply a press to such a superposition A in the up-and-down direction, it becomes difficult to apply a press to the whole, and a chemical | medical solution can be spread over the whole web which comprises superposition A. Various problems such as disappearance are likely to occur. Therefore, it is conceivable to press the wet tissue superimposed body with a strong force. In that case, although the pressure can be applied to the entire wet tissue superimposed body and the chemical solution spreads over the entire web, this time, the wet tissue The entanglement between the webs becomes too strong at the center of the superposed body, and the webs are difficult to separate at the take-out port during use.

  Therefore, Patent Documents 1 and 2 propose a wet tissue superimposed body (superimposed body B) as shown in FIG. The superimposed body B is formed by laminating the web bent body 114. The web bent body 114 is formed by bending the web 100 in the same manner as the web bent body 104 constituting the laminate A except that the formation positions of the bent portions 103 and 103 are changed. It is prepared with. In forming the web bent body 114, the positions where the bent portions 113 and 113 are formed are set so that the free end side of the upper portion 117 extends beyond the bent portion 113 to form the extended portion 118. In this superposed body B, the web bent bodies 114 (114a, 114b) arranged in opposite directions are alternately overlapped to form overlap portions 119a, 119b. The overlap portions 119a and 119b overlap the center portion 115a of the web folded body 114a with the extending portion 118 of the upper portion 117b of the web folded body 114b adjacent below the web folded body 114b. The central portion 115b and the extending portion 118 of the upper portion 117a of the web bent body 114a adjacent to the lower side thereof are overlapped to form each other.

  As described above, according to Patent Literatures 1 and 2, the overlapped portions 119a and 119b are formed by stacking the web bent bodies 114. At this time, since the overlap portions 119a and 119b are formed at positions shifted from the central position (position M) of the wet tissue superimposed body B, an increase in the bulk of the central portion in the superimposed body B is suppressed.

Japanese Patent Laid-Open No. 7-213453 JP-A-8-89439

  By the way, in the wet tissue package, when the web forming the upper wet tissue is taken out from the outlet of the container, the portion constituting the overlap portion of the web forming the lower wet tissue is entangled with the upper web. It moves following this. Then, the lower web moves to the outlet so that it can be dragged by the upper web. When the upper web is pulled out from the outlet, the lower web is also partially pulled out of the container from the outlet. At this time, it is important that the lower web is separated from the upper web in a state where a part of the lower web is pulled out to some extent. In particular, it is important that this is realized with high reproducibility. To that end, it is important that the degree of entanglement between the webs is moderate and that the degree of entanglement between the webs at the overlap portion does not easily change every time the upper web is taken out. .

  However, in Patent Documents 1 and 2, in the wet tissue package, not only the overlap part is formed at a position shifted from the center part, but also the web folded body at the uppermost position and the web adjacent to the lower side thereof. When the overlap portions formed between the folded bodies are viewed, every time the upper wet tissue is taken out, the overlap portions appear alternately at different positions in the plan view of the wet tissue package. Then, the movement of the overlap part when taking out the upper wet tissue is diversified, and the degree of entanglement between the webs at the overlap part is likely to be shaken. For this reason, it is easy to generate entanglement between webs even in parts other than the overlap part, and the degree of entanglement between the webs becomes too strong, and the lower web is partially pulled out from the outlet to some extent. There is also a possibility that they may be taken out together without being separated from the web. In addition, in the wet tissue package of Patent Documents 1 and 2, the area of the overlapping area between the upper and lower webs constituting the overlap portion tends to be large, which also entangles the upper web and the lower web. When the upper web is taken out, the possibility that the lower web is taken out together is increased.

  In view of the above-mentioned problems, the present invention provides a wet tissue superimposed body and a wet tissue package that can suppress the bulkiness of the central portion and can appropriately maintain the degree of entanglement between webs in the overlap portion. The purpose is to provide.

The second web folded body 2b can be formed as follows. In the second web 3b, three positions (positions Sb1, Sb2, and Sb3 in FIG. 3A) that are different from each other in the left-right direction from one end 25 toward the other end 26 are selected. In FIG. 3A, positions Sb1, Sb2, and Sb3 are taken at positions where the distances from the end 25 are Lb1, Lb2, and Lb3, respectively. For the positions Sb1 and Sb2, assuming a quadrant that divides the second web into four equal parts, the position P2 that is in the middle of the positions P1, P2, and P3 where the quadrant should be formed, and the center Is selected as a predetermined position in a region between the positions P1 and P3 of the two quadrants that are further away from each other. The position Sb1 is selected as an area between the positions P1 and P2, and the position Sb2 is selected as an area between the positions P2 and P3. The position Sb3 is selected as a position between the positions Sb1 and Sb2. In the example shown in FIG. 3A, the position Sb3 is selected as the center position of the second web 3b and overlaps the position P2.

  Next, in order from the position close to one end 25 in the left-right direction of the second web 3b among the positions Sb1, Sb2, and Sb3, the second web 3b is placed on the other end 26 side downward, and the second web 3b is folded to form a bellows shape (or a W-shaped longitudinal section) (FIGS. 3B and 3C). At this time, bent portions (first bent portion 4b1, second bent portion 4b2, and middle bent portion 4b3) are formed at positions Sb1, Sb2, and Sb3. And about the part 27, 28, 29, 30 divided by position Sb1, Sb2, Sb3 among the 2nd webs 3b, the part 27 is the 2nd upper piece 8, the parts 28 and 29 are the 2nd center part 9, and the part. 30 forms the second lower piece 10. Thus, the second web folded body 2b is prepared.

[Superposition structure of superposed wet tissue 1]
The wet tissue superposed body 1 has a superposed structure by alternately superposing first web folded bodies 2a and second web folded bodies 2b. At this time, in the wet tissue superimposed body 1, the upper surface side of the lower extension portion 12 and the lower surface side of the first upper piece 5 face each other, and the lower extension portion 12 and a part of the first upper piece 5 overlap each other. The upper extension portion 11 and a part of the first lower piece 7 are overlapped with each other so that the lower surface side of the upper extension portion 11 faces the upper surface side of the first lower piece 7. A portion where the lower extension portion 12 and a part of the first upper piece 5 overlap each other and a portion where the upper extension portion 11 and a part of the first lower piece 7 overlap each other are overlapped portions 13 ( A first overlap portion 13a and a second overlap portion 13b) are formed. Further, in this overlapping structure, the first web folded body 2a has the second web folded body 2b adjacent to the upper side of the first web folded body 2b in the up-down direction. An upper extending portion 11 of a second web folded body 2b located between the upper piece 5 and the first central portion 6 and adjacent to the lower side of the first web folded body 2a It is located between the piece 7 and the first central part 6.

  In the wet tissue superimposed body 1, the second web folded body in which the free end 16 of the first upper piece 5 of the first web folded body 2a is adjacent to the upper side of the first web folded body 2a in plan view. It is preferable that it is located in the formation area (including the base end) of the lower extension 12 of 2b. Moreover, the free end 17 of the 1st lower piece 7 of the 1st web folding body 2a forms the upper extension part 11 of the 2nd web folding body 2b adjacent to the lower side of the 1st web folding body 2a. It is preferably located within the region (including the proximal end) (FIG. 1). In this case, the possibility that the formation part of the overlap part 13 becomes excessively large is effectively suppressed.

  From the viewpoint of further improving the uniformity of the thickness of the wet tissue superimposed body 1, the wet tissue superimposed body 1 has the free end 16 of the first upper piece 5 of the first web folded body 2 a in its plan view. The base end position of the lower extension 12 of the second web bent body 2b adjacent to the upper side of the one web bent body 2a is preferable. Further, the free end 17 of the first lower piece 7 of the first web folded body 2a is connected to the base of the upper extension portion 11 of the second web folded body 2b adjacent to the lower side of the first web folded body 2a. It is preferable to use the end position.

  As shown in FIG. 1, in the wet tissue superimposed body 1, the lower web extending portion 12 and the upper extending portion 11 of the second web folded body 2 b are positioned at the center in the left-right direction of the wet tissue superimposed body 1 in plan view. It is preferable that the 2nd web bending body 2b is piled up as it is. In this case, it is easier to form the overlap portion 13 at approximately the center position when viewed in the left-right direction of the wet tissue superimposed body 1. In FIG. 1, the center position of the wet tissue superimposed body 1 is indicated by the symbol N.

  In the wet tissue superimposed body 1, the distance from the center position N of the first bent portion 4a1 of the first web bent body 2a in the plan view is the first bent portion of the second web bent body 2b. 4a and the second bent portion 4b may be the same as the distance from the center position N, and this is the same for the second bent portion 4a2 of the first web bent body 2a. The first bent portion 4a1 and the second bent portion 4a2 of the web bent body 2a are located on the inner side of the first bent portion 4a and the second bent portion 4b of the second web bent body 2b. (Near the central position N) is preferred. Here, in the wet tissue superimposed body 1, the bent portion 4 is often a portion having a higher hardness than other portions, and a portion having a high hardness is concentrated at a specific location. There is a risk that a partially hard part may occur. In this regard, as described above, the first bent portion 4a1 and the second bent portion 4a2 of the first web bent body 2a are the first bent portion 4a and the second bent portion 4b of the second web bent body 2b. In the case where it is located on the inner side, the positions of such bent portions 4 are shifted from each other, and the hard tissue superposed body 1 is prevented from being concentrated on the left and right edges. can do.

[Preparation of wet tissue superimposed body 1]
The wet tissue superimposed body 1 is prepared as follows. A plurality of first web folded bodies 2a are arranged side by side at a predetermined interval in the vertical direction, and each first web folded body is in a state in which the wet tissue superimposed bodies 1 are alternately reversed in the left-right direction. The body 2a is defined as a left first web folded body 2a1 and a right first web folded body 2a2. At this time, the left direction and the right direction are based on the direction (protrusion direction) of the front end of the first bent portion 4a1 when the superimposed body 1 is viewed from the front of the sheet of FIG. The reason why the first web folded body 2a is divided into a left direction and a right direction is shown in FIG. 1 for the convenience of clarifying that the first web folded body 2a is reversely arranged. Is due to. The same applies to the second web folded body 2b, which will be described later, with leftward and rightward orientations.

  Between the left first web folded body 2a1 and the right first web folded body 2a2, the second web folded body 2b is adjacent to the right first web folded body 2a2 at the upper and lower positions. Deploy. At this time, the second web folded body 2b positioned on the upper side and the lower side is shifted in the vertical direction while being reversed so as to be opposite to each other in the left-right direction of the wet tissue superimposed body 1. The second web folded body 2b1 facing left and the second web folded body 2b2 facing right are formed. At this time, the left direction and the right direction are based on the direction of the front end of the first bent portion 4b1 when the superimposed body 1 is viewed from the front of the sheet of FIG.

  The left second web folded body 2b1 which is adjacent to the upper side with respect to the right first web folded body 2a2 has a lower extension portion 12 as the first upper piece 5 of the left first web folded body 2a2. Between the first central portion 6 and the first central portion 6. The left-facing second web bent body 2b1 is arranged so that the lower surface of the first upper piece 5 faces the upper surface of the lower extension 12 thereof.

  The right-facing second web folded body 2b2 which is adjacent to the lower side with respect to the right-facing first web folded body 2a2 has an upper extension portion 11 as a first lower piece of the right-facing first web folded body 2a2. 7 and the first central portion 6. The right-facing second web folded body 2b2 is arranged so that the upper surface of the first lower piece 7 faces the lower surface of the upper extension portion 11 thereof.

  On the upper side of the left-facing second web folded body 2b1, the left-facing first web folded body 2a1 is adjacently disposed. The left first web folded body 2a1 is arranged so that the upper surface of the first lower piece 7 faces the lower surface of the upper extension 11 of the left second web folded body 2b1.

  A left-facing first web folded body 2a1 is disposed adjacent to the lower side of the right-facing second web folded body 2b2. The left first web folded body 2a1 is disposed so that the lower surface of the first upper piece 5 faces the upper surface of the lower extension 12 of the left second web folded body 2b1.

  Thus, as shown in FIG. 1, from the upper layer toward the lower layer, the first web folded body 2a (2a1), the second web folded body 2b (2b1), the first web folded body 2a (2b2), the first A laminated structure is formed in the order of the two web folded bodies 2b (2b2), and the wet tissue superimposed body 1 is prepared by sequentially laminating on the lower layer side (or the upper layer side) according to the number of webs to be laminated. . Note that the web folded body 2 at the top and bottom of the wet tissue superimposed body 1 may be either the first web folded body 2a1, 2a2 or the second web folded body 2b1, 2b2. In addition, about the web folding body 2 in the highest rank and the lowest rank, the presence of the structure which laminates | stacks the web folding body 2 adjacent to an upper side and a lower side, respectively is unnecessary.

[Function of wet tissue superimposed body 1]
In the wet tissue superimposed body 1, the second central portion 9 of the second web folded body 2 b is formed in a portion around the portion where the overlap portion 13 exists (portion 31 in FIG. 1) in plan view. Is arranged. At this time, the middle bent portion 4b3 of the second web 2b may be positioned at the end of the portion 31 in the plan view of the wet tissue superimposed body 1. Then, even if the web folding bodies 4 overlap each other and the overlap portion 13 is formed and the number of laminations increases, there is a portion where the second central portion 9 exists around the portion 31 as described above. The increase in the number does not occur more in the portion 31 than in the surrounding portion of the portion 31, and the possibility that the portion 31 of the wet tissue superimposed body 1 becomes larger and bulkier than the other surrounding portions is suppressed. Is done. That is, as shown in the example of FIG. 1, even if the overlap portion 13 is formed in the central portion of the wet tissue superimposed body 1, the risk of becoming bulky in the central portion of the wet tissue superimposed body 1 is suppressed. Accordingly, the wet tissue superimposed body 1 can be made to have a substantially uniform thickness, and it becomes easy to uniformly apply pressure to the wet tissue superimposed body 1 when preparing the wet tissue package 40 described later.

  In the wet tissue superimposed body 1, the overlap portions 13 are formed so as to be aligned in a line in the vertical direction. That is, the 1st overlap part 13a and the 2nd overlap part 13b are located in a line by turns. Thereby, every time the web 3 is taken out from the wet tissue packaging body 40 which stores the wet tissue superposed body 1 described later, the possibility that the position of the overlap portion 13 is largely changed in the left-right direction is suppressed, and the degree of entanglement between the webs 3 is suppressed. The possibility that the web 3 becomes stronger or weaker is also suppressed, and it becomes easier to keep the degree of entanglement between the webs 3 in an appropriate state. In the wet tissue superimposed body 1, the sizes of the first overlap portion 13a and the second overlap portion 13b are adjusted to an appropriate size by appropriately changing the position of the second web folded body 2b. Therefore, the possibility that the first overlap portion 13a and the second overlap portion 13b become too large and the entanglement between the webs 3 becomes excessively large is also suppressed.

[Wet tissue package 40]
As shown in FIG. 4, the wet tissue package 40 is obtained by storing the wet tissue superimposed body 1 in the storage body 32. The container 32 is a container or a bag, and has a shape that can accommodate the wet tissue superimposed body 1. The container 32 is provided with an outlet 33 on the upper surface side.

  In order to prevent volatilization of the chemical liquid impregnated in the web 3 from the outlet 33, the upper surface of the outlet 33 may be sealed in the container with an adhesive film (not shown). A commercially available seal | sticker etc. can be used suitably as an adhesive film.

  When sealing the outlet of the container 33, it is important to stick an adhesive film to the container 32 without any gap. However, when the container 32 is a bag body, due to the flexibility of the bag body, if the outer shape of the wet tissue superimposed body 1 to be stored has large irregularities, the irregular shape is reflected in the shape of the bag body. Therefore, even if an adhesive film is to be attached to the outlet 33, it is difficult to seal the container with the adhesive film without a gap with respect to the outlet of the container. Sealing with an adhesive film without a gap is extremely important due to the characteristics of a product called wet tissue. Specifically, the reasons for this are that it is important that the wet tissue is as dry as possible until it is ready for use. For example, the web should not be contaminated by entering. In this regard, the wet tissue superimposed body 1 of the present invention has a superimposed structure of the first web folded body 2a and the second web folded body 2b as described above, and suppresses the bulkiness of the central portion. Since the occurrence of unevenness is suppressed, it is easy to attach the adhesive film to the bag body containing the wet tissue superimposed body 1 without a gap.

  The present invention is useful in the use of a wet tissue that wipes off dirt and the like.
