It is a figure for demonstrating one process in the manufacturing method of the container by one form of this invention. 1 is a perspective view of a container according to the prior art.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, unless otherwise specified, the same or corresponding components may be denoted by the same reference symbols and description thereof may be omitted.

  FIG. 1 shows a perspective view of a container 1 according to an embodiment of the present invention. Moreover, the typical sectional drawing which cut the container 1 of FIG. 1 by the II line in FIG. 2 is shown. The container 1 is made of a flexible film, and as shown in FIG. 2, a container main body 10 having a space capable of containing a stack of thin paper sheets, and a paper lead-out portion connected to the upper portion of the container main body 10 It has 20 and. In the illustrated embodiment, the container body 10 and the paper extraction unit 20 are integrally formed. The paper extraction unit 20 has a thin paper outlet 40. The thin paper can be pulled out from the outlet 40 along the first direction D1 (forward in the first direction D1) in top view.

  The flexible film constituting the container 1 includes polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), polyvinyl chloride (PVC), ethylene-vinyl acetate copolymer (EVA) General-purpose resin film generally used as a container of thin paper, such as polyamide (PA), can be used. As the material of the flexible film, polyethylene, polypropylene, polyethylene terephthalate and the like are preferable because they are flexible and excellent in handleability, high in sealing ability when heat sealed, and inexpensive, and they are odorless, water resistant Polyethylene is more preferable because it is excellent in resistance and chemical resistance and can be mass-produced at low cost. As polyethylene, high density polyethylene, low density polyethylene and the like can be used, and low density polyethylene is preferable because it is excellent in flexibility. Further, the flexible film may be a laminate film in which a plurality of films are laminated, or may be a film composed of a mixture of two or more of the above resins.

  The thickness of the flexible film is preferably 20 to 70 μm, and more preferably 30 to 60 μm. By setting the thickness of the flexible film to 20 μm or more, sufficient strength as a container can be secured. In addition, by setting the thickness of the flexible film to 70 μm or less, sufficient flexibility for facilitating deformation of the container at the time of taking out the thin paper and at the time of storing the thin paper described later is ensured, and the cost is suppressed. be able to.

  In the illustrated embodiment, the container 1 has a substantially rectangular solid shape as a whole, and the second one is orthogonal to the first direction D1 in a top view from the length of the first direction D1 along the drawing direction of the thin paper. The length of the direction D2 is longer. However, the container 1 may have another three-dimensional shape depending on the shape of the stack of thin paper sheets to be stored. For example, the housing may have another shape such as a cube, and the length of the first direction D1 may be equal to the length of the second direction D2, or may be longer than the length of the second direction D2. You may

  As shown in FIG. 2, the paper extraction unit 20 includes a lower guide 21, an upper guide 22, and a lid 23. The upper guide 22 is stacked on the lower guide 21. That is, both are arranged so that at least one part may overlap. The lower guide 21 and the upper guide 22 have a function of guiding the thin paper when the thin paper is pulled out. In addition, the lid 23 is stacked on the upper guide 22. That is, both are arranged so that at least one part may overlap. The lid 23 has a function of covering the upper surface of the container 1.

  The lower guide 21 has an end 21 e on the front side in the first direction D1. The end 21 e of the lower guide 21 is not connected to the other components of the housing 1, and the lower gap 31 is formed between the end 21 e of the lower guide 21 and the housing body 10. . Further, the upper guide 22 has an end 22e at the rear in the first direction D1. The end 22e of the upper guide 22 is also not connected to the other components of the container 1, and the upper gap is formed between the end 22e of the upper guide 22 and the connection 25 between the lower guide 21 and the lid 23. 32 are formed. The position of the end 21e of the lower guide 21 and the position of the end 22e of the upper guide 22 are separated in the first direction D1 in top view as shown in FIGS. 1 and 2.

  The lower gap 31 and the upper gap 32 become a passage when the thin paper is pulled out, and when the thin paper is pulled out, as shown by the arrows in FIG. 2, the advancing direction of the thin paper is the lower gap 31 and the upper clearance It is converted at 32. Therefore, the thin paper pulled out from the laminate 3 is turned to the rear in the first direction D1 at the end 21e of the lower guide 21, passes between the lower guide 21 and the upper guide 22, and the end of the upper guide 22 The portion 22e is turned forward in the second direction D1 and passes between the upper guide 22 and the lid 23 to reach the outlet 40.

  Thus, the laminated body 3 of the thin paper is not exposed to the outside from the outlet 40 because the paper drawing portion 20 has a structure in which the lower guide 21, the upper guide 22 and the lid 23 are laminated. Therefore, even after the use of the container 1 is started, it is difficult for dust, dirt, and the like to get into the container body 1. When a thin paper product including the thin paper stack 3 and the container 1 is carried by putting it in a bag, etc., the thin paper stack 3 is the inner surface of the bag or other articles in the bag. Although the thin paper may be rubbed or soiled by coming into contact with it, according to this embodiment, it is possible to prevent such deterioration of the thin paper.

  Furthermore, according to the present embodiment, the possibility that the laminate 3 of thin paper sheets is in direct contact with the open air can be reduced, so in the case where the thin paper 2 is a thin paper to which a chemical solution containing a specific component is attached, The volatilization of the chemical solution can be suppressed, and its action can be maintained. For example, when a tissue paper to which a liquid containing a moisturizing component is attached is used, that is, when the tissue is a moisturizing tissue, this embodiment can prevent the tissue from drying and maintain its moisturizing property. Moreover, when the thin paper to which the chemical | medical solution containing an aromatic component was made to adhere is used, it can prevent that an aromatic component volatilizes early and an aroma is lost.

  Further, according to the configuration of the paper drawing portion 20 described above, the thin paper before being drawn out from the laminated body of the thin paper is drawn out in a zigzag shape, and between the lower guide 21 and the upper guide 22 and the upper guide 22 The sheet can be held by the paper extraction unit 20 in a state of being sandwiched between the cover 23 and the cover 23 (FIG. 2). Therefore, it is possible to reduce the possibility of direct contact of the thin paper before removal with the open air. Further, even in the configuration of being drawn out in a zigzag shape as described above, since the container 1 is formed of a flexible resin film, the thin paper can be taken out smoothly.

  FIG. 3 shows a schematic cross-sectional view taken along the line II-II in FIG. In the illustrated embodiment, the lower guide 21 is folded back into two layers, and the lower guide 21, the upper guide 22 and the lid 23 are stacked in this order from the bottom. The four layers of the stacked paper lead-out portion 20 are fixed together at both ends in the second direction D2, whereby the fixing portions 50, 50 are formed. The fixing parts 50, 50 are parts fixed along the first direction D1 as shown in FIG. Further, the fixing portions 50, 50 project in opposite directions to each other in the second direction D2 and can be gripped. The fixing portions 50, 50 can be formed, for example, by heat-sealing together the above four layers of the paper lead-out portion 20 and the film of the containing body 10 and heat sealing. The fixing portions 50 can also be formed by adhesion with an adhesive or sewing.

  Next, the function of the container 1 will be more specifically described with reference to FIGS. 4A to 4C and 5A to 5C. 4A to 4C are perspective views of a thin paper product 100 comprising a container 1 and a laminate of thin paper, and FIGS. 5A to 5C are cross-sectional views of the container 1 taken along the line I-I. FIGS. 4A to 4C respectively correspond to FIGS. 4A to 4C. FIG. 4A and FIG. 5A show a state after the end of the thin paper 2a located between the upper guide 22 and the lid 23 of the paper drawing out part 20 has been drawn out of the extraction opening 40 a little. 4B and 5B show a state in which the subsequent thin paper 2b has been ejected from the outlet 40 after drawing out the thin paper 2a, and FIGS. 4C and 5C show the deformed container 1 in the state shown in FIGS. 4B and 5B. The drawing shows the state after the ejected thin paper 2b is stored by pulling the fixing portions 50, 50 in the directions opposite to each other.

  As shown to FIG. 5A-FIG. 5C, the laminated body 3 of thin paper is accommodated in the interior space of the container main body 10. As shown in FIG. The paper stack 3 is configured such that the paper is pulled out in a pop-up manner. For example, a thin paper sheet is folded in two so that the folding direction is alternated, and the edges of the folded surface are respectively inserted into the folded inner surface of the adjacent thin paper sheet, that is, inserted alternately It is stacked in a broken state. Then, when one set or a set of stacked sheets is taken out, the subsequent sheets will be partially ejected to the outside. The tissue sheet may be folded in three or four as long as it can be pulled out in a pop-up manner.

  The thin paper is folded and stacked so that it can be pulled out in a pop-up manner, so the thin paper pulled from the thin paper laminate 3 maintains the overlap with the subsequent thin paper, and the lower gap 31 and the lower guide The space between the upper guide 22 and the upper guide 22, the upper gap 32, and the space between the upper guide 22 and the lid 23 are sequentially passed through to reach the outlet 40. Therefore, when the leading end of the thin paper 2a is pulled out, the subsequent thin paper 2b is also pulled out following the thin paper 2a. Then, when the thin paper 2a has been pulled out, the front end of the subsequent thin paper 2b reaches the vicinity of the outlet 40 or the outlet 40, and as shown in FIGS. 4B and 5B, the thin paper 2b pops out from the outlet 40 It will be in the exposed state. At this time, since the thin paper 2b is changed in direction at the rear end 22e of the upper guide 22 in the first direction D1, the degree of popping out can be reduced (the popping out resistance can be made favorable), and popping out The exposure of subsequent paper can be reduced.

  As described above, when taking out the thin paper 2a, the container 1 can receive force from the thin paper and can be deformed into a generally bulging appearance as shown in FIGS. 4B and 5B. Specifically, the vicinity of the central portion of the lid 23 is lifted (FIGS. 4B and 5B). Also in the paper extraction unit 20, the end 22e of the upper guide 22 is lifted and pushed forward in the first direction D1 by a force from the subsequent thin paper (FIG. 5B). Further, the fixing portions 50, 50 at both ends of the second direction D2 are also drawn to the center to a certain extent as viewed in the second direction D2 (FIG. 4B). Also, the same deformation as the upper guide 22 may occur at the end 21 e of the lower guide 21 due to the force from the subsequent thin paper. That is, the end 21 e of the lower guide 21 is lifted and pushed and bent rearward in the first direction D1.

  As described above, the fixing portions 50, 50 are formed at both ends in the second direction D2 of the container 1, and the fixing portions 50, 50 can be gripped (FIG. 1, FIG. 3). Therefore, when the removal of the thin paper is ended once, the entire expanded container is held by gripping both fixing portions 50, 50 and pulling them in opposite directions (arrows in FIG. 4C) along the second direction D2. The shape of 1 can be restored. Specifically, the shape of the lid 23 whose central portion has been lifted is re-deformed into the original flat shape. In addition, the end 22e of the upper guide 22 whose central portion is lifted upward and pushed forward in the first direction D1 is pushed downward and returned to the rear in the first direction D1. With this re-deformation, the end 22e of the upper guide 22 can pull back the tissue 2b to the rear in the first direction D1. In addition, the end 21e of the lower guide 21 whose central portion is lifted upward and pushed and bent backward in the first direction D1 is also pushed downward and returned forward in the first direction D1. Along with this, the end 21e of the lower guide 21 can pull back the succeeding thin paper sheet forward in the first direction D1.

  As described above, when the upper guide 22 returns to its original shape when the fixing portions 50, 50 are pulled in the opposite direction to each other along the second direction D2, the thin paper is mainly from the end 22e of the upper guide 22. Receive power. Here, the front end side of the thin paper 2b is in a free state, while the rear end side is overlapped with the next thin paper and continues to the laminated body 3 of the thin paper, and from the end 22e of the thin paper 2b to the front end The length of the side is shorter than the length of the rear side. Therefore, even if the thin paper 2b receives a force from the end 22e of the upper guide 22, the rear end side of the thin paper 2b does not move, and the front end moves and is pulled back.

  By the above-described pull-back action, the thin paper 2b that has been ejected from the outlet 40 can be reliably stored in the inside of the paper pull-out portion 20 (the storability is good). This storage can be done without touching the tissue by hand. Therefore, it is not necessary to use a hand to push the ejected paper into the container 1 and it is hygienic. Furthermore, since the thin paper pulled back to the paper extraction unit 20 is held in the paper extraction unit 20, the thin paper does not directly touch the outside air, or the portion directly touched becomes small. Therefore, even when a medical solution containing components such as a moisturizing component and an aroma component is attached to a thin paper, volatilization of the chemical solution can be suppressed, and actions such as moisturizing and aroma can be maintained.

  When the fixing portions 50, 50 are pulled, the back side of the fixing portions 50, 50 (backward in the first direction D1), the near side (frontward in the first direction D1), or the middle (center in the first direction D1) ) Or may be pulled several times.

  In the embodiment described above, the lower guide 21 is connected to the housing body 10 at the rear in the first direction D1, and the upper guide 22 is connected to the housing body 10 at the front in the first direction D1 (see FIG. 2, 5A-5C). That is, the lower guide 21 extends forward from the housing body 10 in the first direction D1, and the upper guide 22 extends rearward from the housing body 10 in the first direction D1. Thus, the lower guide 21 and the upper guide 22 are integrated with the housing body 10. Since one of the lower guide 21 and the upper guide 22 or both the lower guide 21 and the upper guide 22 is connected to the housing body 10 in the first direction D1, the shapes of the lower guide 21 and the upper guide 22 and thus the housing The shape of the entire body 1 can be stabilized. Moreover, the sealing performance of the container 1 can also be improved.

  Furthermore, when the lower guide 21 is connected to the main body 10 at the rear in the first direction D1 and the upper guide 22 at the front in the first direction D1 as described above, the housing 1 deformed after the thin paper 2a is pulled out The upper guide 22 and the lower guide 21 follow the container body 10 even when the shape of the container 1 is restored by pulling the container 1 along the second direction D2. It becomes easy to return to the shape. Therefore, the above-mentioned pull back action by the upper guide 22 and the lower guide 21 can be improved.

  Further, in the present embodiment, the lower guide 21 is folded back, and the folded back portion formed by the folding forms the front end 21 e of the lower guide 21 in the first direction D 1 (FIG. 2, FIG. 3, 5A-5C). In such a configuration, since the lower guide 21 has two layers, the force that the thin paper sheet receives from the lower guide 21 when the lower guide 21 is deformed is larger than when the lower guide 21 is not folded back. Therefore, the above-mentioned pullback action by the lower guide 21 can be enhanced.

  Further, the lower guide 21 and the lid 23 are integrally formed, and the connection portion 25 connecting them is a folded portion (FIG. 2, FIG. 5A to FIG. 5C). Thereby, when the container 1 is deformed, the lower guide 21 and the lid 23 follow the container 1, so that the fixing portions 50, 50 are gripped and the container 1 is pulled along the second direction D2. In this case, the pulling back action of the thin paper by the lower guide 21 can be enhanced. Further, since the lower guide 21 and the lid 23 are integrally formed, the lower guide 21 and the lid can be formed by folding back the film without separately producing the lower guide 21 or the lid 23 or both of them. The 23 parts can be easily made. Furthermore, when the container 1 is pulled in the opposite direction along the second direction D2, the gap between the lid 23 and the upper guide 22 can be narrowed, so the thin paper in the paper drawer 20 contacts with the open air. The possibilities can be further reduced.

  It is preferable that the length of the upper guide 22 in the first direction D1 is 80 to 120% of the length of the first direction D1 of the thin paper stack 3. By making the length of the upper guide 22 in the first direction D1 80% or more of the length of the stacked body 3 in the first direction D1, the sealing performance of the container 1 is improved, and the above-described pull back by the upper guide 22 is performed. The action can be enhanced, and by setting it to 120% or less, the load applied to the thin paper at the time of taking out can be reduced, and the ease of taking out can be secured. When the length of the upper guide 22 in the first direction D1 is 100% or more of the length of the stack 3 of thin paper sheets in the first direction D1, a particularly high pull back effect can be obtained, and the thin paper can be pulled out. The effect of storing in the unit 20 is enhanced. The length of the upper guide 22 in the first direction D1 can be, for example, 80 to 125 mm.

  The length of the lower guide 21 in the first direction D1 is not particularly limited, but preferably 40 to 110% of the length of the first direction D1 of the thin paper laminate 3 and 50 to 90%. More preferable. By making the length in the first direction D1 of the lower guide 21 into the above range, the sealing performance of the container 1 can be improved, and the above-described pullback action by the lower guide 21 can be enhanced. In this case, the load applied to the thin paper can be reduced, and the easiness of withdrawal can be ensured.

  One aspect of the present invention relates to a method of manufacturing a container and a method of manufacturing a thin paper product including a container and a laminate of thin paper. According to this aspect, the thin paper products can be manufactured by so-called pillow packaging. Hereinafter, the manufacturing method of the storage body 1 of the form demonstrated with reference to FIGS. 1-3, and the manufacturing method of a thin paper product containing the storage body 1 and the laminated body of thin paper are demonstrated.

  In the present embodiment, the container 1 can be manufactured from, for example, one film 8 as shown in FIG. The film 8 has a central region R3, a first region R1 adjacent to one side of the central region R3, and a second region R2 adjacent to the other side of the central region R3.

  After preparing one flexible film as described above, the stack 3 of thin paper sheets is placed at the center of the central region R3. Subsequently, the first region R1 and the second region R2 are overlapped, and the film is put on the stacked body 3 of the mounted thin paper so that the film has a tubular shape. At this time, the first region R1 is folded upward in a zigzag shape, whereby the lower guide 21 folded back at the first folded portion 21e and the lid 23 as shown in FIG. 2 are formed. The second region R2 is inserted between the lower guide 21 formed from the first region R1 and the lid 23 simultaneously with or after the step of zigzag folding the first region R1. As a result, as shown in FIG. 2, the paper extraction unit 20 in which the lower guide 21, the upper guide 22, and the lid 23 are stacked in this order is formed.

  Thereafter, both ends of the cylindrical flexible film are sealed by heat sealing or the like to seal them. By this sealing step, fixing portions 50, 50 as shown in FIG. 1 and FIG. 3 are formed.

The tissue paper used in one embodiment of the present invention may be a hygienic tissue paper such as tissue paper, toilet paper, kitchen paper, paper hand towel, paper cloth, wiper and the like. The basis weight of one ply of thin paper is preferably 10 to ²⁰ g / m ² , and the thickness of two plies of thin paper is preferably 130 to 200 μm. The basis weight is determined by the basis weight measurement method of JIS P 8124 (1998).

  Further, the dimensions of the laminate of thin paper may be such that the length in the first direction D1 is about 80 to 115 mm, the length in the second direction D2 is about 180 to 250 mm, and the height is about 30 to 90 mm. Such stacks of tissue paper can be produced, for example, by means of a rotary or multistand interfolder.

  Since the container according to one aspect of the present invention can maintain the function of protecting the thin paper even after the start of use as described above and can maintain the sealing property, it applied a drug solution such as so-called moisturizing tissue or lotion tissue. It can be suitably used as a container for containing a laminate of thin paper.

  Hereinafter, the embodiments of the present invention will be described in more detail by way of examples, but the present invention is not limited to these examples.

  In this example, a container containing a laminated body of thin paper was prepared, and the water retention, feel, pop-out resistance, and storability were evaluated.

Example 1
A container containing a thin paper was prepared by pillow-wrapping a laminated body of thin paper using a long polyethylene (PE) film (film thickness: 50 μm, manufactured by Fukusuke Kogyo Co., Ltd.) having a width of 325 mm. As a thin paper to be stored in the container, a tissue paper coated with a moisturizing solution (manufactured by Daio Paper Co., Ltd., "Eliaire luxury moisturizing"), a so-called moisturizing tissue was used. The tissue paper is 50 pairs (100 sheets) consisting of a stack of 2 sheets, and it is 103 mm in width (length in the first direction D1), width The length of the second direction D2 was 223 mm, and the height of the laminate was 25 mm.

  The container has a structure as shown in FIGS. 1 and 2, and the depth (length in the first direction D1) is about 115 mm, and the width (length in the second direction D2) is flat as a thin paper product. The length of the upper surface portion was about 240 mm and the height was about 55 mm. Further, when viewed in the first direction D1, the length of the lower guide 21 was 90 mm, the length of the upper guide 22 was 110 mm, and the length of the lid 23 was 123 mm. The width of the upper guide and the lower guide (the length in the second direction D2, the length of the film to the fixing margin of the fixing portion) was 310 mm. The upper guide 22 and the lower guide 21 stacked under the upper guide 22 are partially joined by heat sealing along the second direction D2, as shown in FIGS. The length of the second direction D2 was 170 mm.

(Examples 2 to 10)
A container was produced in the same manner as in Example 1 except that the length in the second direction D2 of the upper guide 22, the lower guide 21 and the upper gap 32 was changed to a value shown in Table 2.

(Comparative example 1)
Using a film of the same material, width, and thickness as the film used in Example 1, a container such as container 1A shown in FIG. Got ready. This container is used in such a manner that the perforations are broken at the time of use to form the outlet, and the sheet of the paper sheet is pulled out from the outlet. The perforation length of the container of Comparative Example 1 was 170 mm.

(Comparative example 2)
A container was produced in the same manner as in Example 1 except that the length in the second direction D2 of the upper guide 22, the lower guide 21 and the upper gap 32 was changed to a value shown in Table 2. In the container of Comparative Example 2, the upper guide 22 and the lower guide 21 are not stacked.

  Evaluation was performed about the container of Examples 1-10 and Comparative Examples 1 and 2 which were produced as mentioned above. The water retention and feel were evaluated for Example 1 and Comparative Example 1, and the pop-out resistance and storage property were evaluated for Examples 1 to 10 and Comparative Example 2. Each evaluation result of tactile sense is shown in Table 1, and each evaluation result of popping-out resistance and storability is shown in Table 2.

The method of each evaluation is as follows:
[Water retention]
From each of the prepared containers, up to 10 sets of tissue paper are pulled out from the laminate one by one under an environment of temperature 25 ° C. and relative humidity 45%, and each tissue paper is folded in two in the first direction D1. The water content (%) was measured at three locations along the second direction D2 (the center of the second direction D2 and before and after). The moisture content was measured by an electric moisture meter (manufactured by Sanko Electronics Research Institute, model: MR-200 II), and the average value of the values measured at the above three locations was recorded. Furthermore, the average value of the moisture content of 1 to 10 sets was determined, and this value was recorded as “water content before drying”.

  Thereafter, the container after pulling out the first to tenth sets of tissue paper is placed in a desiccator (type Endo, made by Endo Chemical Co., Ltd., made by Endo Chemical Co., Ltd.) adjusted to a temperature of 25 ° C. and a relative humidity of 10% with silica gel. Leave for 72 hours to dry. After drying, the top ten sets of tissue papers (11th to 20th groups in total) were pulled out of the laminate, and the moisture content of each set of tissue papers was measured in the same manner as before drying. The average value of the moisture content of the 11th to 20th groups was determined, and this value was recorded as "water content after drying." Furthermore, based on the values of “water content before drying” and “water content after drying”, the water retention ratio (= (water content after drying) / (water content after drying) × 100) (%) I asked for.

[Touch (Sensory evaluation)]
Each of the prepared containers was left to dry for 48 hours in a desiccator (Model Endo, manufactured by Endo Chemical Co., Ltd., manufactured by Endo Chemical Co., Ltd.), which was conditioned with silica gel at a temperature of 25 ° C. and a relative humidity of 10%. After drying, nine evaluators evaluated the tactile sensations of "softness", "moist feeling", "smoothness", "firmness feeling", and "puffy feeling". Evaluation was made into the numerical value evaluated by the following standard to evaluation (4.0) of comparative example 1. The arithmetic mean of the ratings of all raters was recorded.
1: Fairly bad 2: Bad 3: Slightly bad 4: Same as Comparative Example 1 5: Slightly good 6: Good 7: Good: quite good

[Pump-out resistance]
Attach the double-sided tape (Nichiban Co., Ltd., “Nystack NW-15”) 15 x 210 mm at a position 10 mm away from each end of the back of the package in the first direction D1 to make the container flat Fixed. The central portion of the tip of a pair of tissue papers exposed from the lid, as viewed in the second direction D2, was sandwiched by an eyeball clip ("Kurio 13" manufactured by KOKUYO CO., LTD.). Insert a hook of a push pull gauge (made by Imada Co., Ltd., model number: Z2-20) into one hole of the handle part of the eyeball clip, and maintain a force of 0.7 ± 0.6 N from the container Tissue paper was pulled out in the first direction D2. Such drawing of the tissue paper is performed for all the 50 sets of tissue paper accommodated, and every time one group is taken out, the next set of tissue paper is 68 mm as viewed in the first direction D1 (tissue paper The number of popping out more than 1/3) was recorded as the number of popping out groups.

Evaluation of popping-out resistance was performed as follows. The smaller the number of sets of pop-outs, the smaller the pop-out properties, which is preferable. △ or more is a good result.
:: Number of jumping out groups is 0
:: Number of sets of 1 to 15
:: Number of jumpout groups is 16 to 20
X: Number of jumpout groups is 21 or more

[Storability]
The tissue paper was taken out in the same manner as the method described above in the evaluation of the above-mentioned pop-out resistance. Then, after taking out one set of tissue paper, the two fixing portions 50, 50 were grasped and pulled three times in opposite directions to each other in the second direction D2. At that time, the first time grips the back side of the fixed portions 50, 50 (rear of the first direction D1), and the second time grips the near side of the fixed portions 50, 50 (forward of the first direction D1) The third time, grasped and pulled at the same position as the first time. The number of sets that were not completely stored (the number of sets of tissue paper that had exited even a little from the outlet) was recorded as the number of incompletely stored sets.

Evaluation of storability was performed as follows. The smaller the number of incompletely stored sets, the better the storage performance, which is preferable. △ or more is a good result.
:: The number of incomplete storage groups is 10 or less :: The number of incomplete storage groups is 11 to 20
Δ: Number of incompletely stored sets is 21 to 49
X: Number of incomplete storage groups is 50 (storage of all groups was incomplete)

  As shown in Table 1, it was found that the water retention rate of Example 1 was improved as compared to Comparative Example 1 (the conventional container shown in FIG. 11). In addition, in Example 1, the sensory evaluation was also equal to or higher than Comparative Example 1, and it was found that the performance of the moisturizing tissue after storage in a dry environment is superior to that of Comparative Example 1.

  As shown in Table 2, Examples 1 to 10 are compared with Comparative Example 1 which is a conventional container having no upper guide and lower guide, and Comparative Example 2 in which the upper guide and the lower guide are not stacked. Were found to be excellent in pop-out resistance and storability. In particular, in Examples 1 to 9 in which the upper guide and the lower guide are partially joined by heat sealing along the second direction D2, in particular, the upper guide length is the first direction D1 length of the laminate of thin paper ( It turned out that Examples 1 and 4-9 which are 100% or more of 103 mm) are especially excellent in storability. Further, in Examples 1, 4 to 6 and 10 (the length of the upper gap is 70% or more of the length in the second direction D2 (223 mm) of the laminate), the pop-out resistance was particularly good (tissue paper It was hard to jump out).
