[Effects of the invention]

According to the packaging body described in (1) of the present invention, the edge portion includes: a pair of extended existing portions having cuts extending in the direction in which the sealing paper is torn off; The pair of extended portions are further connected to the side where the sealing paper is torn off and the ends of the pair of extended portions, and form a convex arc toward the side opposite to the direction in which the sealing paper is torn off, and have a deeper depth than the extended portion. Cut marks, and achieve the following effects. Since the thin-walled portion of the edge portion has a deeper cut than the extended portion, it is possible to reduce the force when the thin-walled portion of the edge portion is used as a starting point to cut and separate the portion. Once the cut-off portion is cut off at the thin-walled portion, it is cut off along the pair of extended existing portions following the cut-off of the thin-walled portion. Therefore, compared with the case where the cut is formed with the same depth along the outer shape of the cut-off part, it is easier to cut the cut-off part. That is, when the sealing paper is peeled off, it is possible to suppress the case where the extraction port is not formed or the case where it is not formed into the desired shape. In addition, since it is easy to make the cut in the extended portion shallow, even if the cut in the thin-walled portion is deepened, it is possible to suppress the cut-off portion during manufacturing (before the sealing paper is attached to the main body of the take-out surface). Circumstances of deviation or deviation. Therefore, the extraction port can be stably formed into a desired shape. In addition, the airtightness of the package is maintained, and the intrusion of foreign matter can be suppressed.

According to the packaging body described in (2) of the present invention, since the edge portion is further provided with a pair of connecting portions, a pair of ends and a thin wall of the thin-walled portion of the extending portion are connected in the direction in which the sealing paper is torn off. At both ends of the part, the depth of the cut marks from the side of the thin-walled part toward the side of the extending part gradually becomes shallower, and the following effects are achieved. Since there is a connecting portion between the thin-walled portion and the extended portion, the difference in the depth of the cut of the thin-walled portion and the extended portion gradually decreases. Therefore, the cut-off portion can be smoothly cut off along the pair of connecting portions and the pair of extended portions starting from the thin-walled portion of the edge portion. Therefore, it is easier to cut away from the cut part.

According to the packaging body described in (3) of the present invention, since the sheet body is a liquid-containing sheet, the following effects are achieved. The airtightness of the package is maintained, and the drying of the liquid-containing flakes can be suppressed.

According to the packaging body described in (4) of the present invention, since the cut marks are formed on the side of the sealing paper of the take-out surface body, but are not formed on the side opposite to the sealing paper of the take-out surface body, the following effects are achieved. Compared with the case where the cut marks are formed on the side opposite to the sealing paper of the take-out surface body, the airtightness of the package can be maintained more effectively.

According to the packaging body described in (5) of the present invention, since the cut is formed on the side opposite to the sealing paper of the take-out surface body but not on the side of the sealing paper of the take-out surface body, the following effects are achieved. Compared with the case where the cut marks are formed on the side of the sealing paper of the take-out surface body, it is easier to cut the cut-off portion from the take-out surface body when the sealing paper is torn off.

According to the packaging body described in (6) of the present invention, since the sheet is a liquid-containing sheet, and the take-out surface body is a laminated sheet with multiple layers, the cut marks on the extended portion and the cut marks on the thin-walled portion are formed only on the multiple layers In the first layer, and achieve the following effects. Because the liquid does not penetrate into the interlayer of the laminated sheet, the interlayer peeling is not easy to occur.

According to the packaging body described in (7) of the present invention, since the take-out surface body is a laminated sheet of plural layers, the following effects are achieved. Overlapping layers that do not easily pass moisture and layers that are easy to develop color in printing, etc., allow the take-out surface body to have multiple functions.

According to the packaging body described in (8) above of the present invention, the cut in the extended portion is formed in layers other than the last layer in the plurality of layers, and the cut in the thin-walled portion penetrates the first layer of the plurality of layers, and To achieve the following effects. Since there is no cut mark of the extended portion in the last layer, the cut-off portion can be easily cut away from the main body of the take-out surface while maintaining the airtightness of the package.

According to the packaging body described in (9) of the present invention, since the cut in the thin-walled portion penetrates the first layer of the plurality of layers to the last layer, and is formed in the last layer, the following effects are achieved. In the thin-walled part, the cut marks are formed to the last layer of the laminated sheet. Therefore, the cut-off part can be cut away from the main body of the take-out surface while suppressing delamination between the layers.

According to the container described in the above (10) of the present invention, since it has the same structure as the above-mentioned packaging body, the following effects are achieved. Therefore, the extraction port can be stably formed into a desired shape. In addition, the airtightness of the container is maintained, and the intrusion of foreign matter can be suppressed.

According to the packaging body described in (11) of the present invention, the edge portion includes a pair of extended portions with cut marks, which are connected to both ends of a curve that is convex toward the side opposite to the direction in which the sealing paper is torn off. Extending in the direction in which the sealing paper is torn off; and the stopper part, which is provided in the middle of the extending part, is thicker than the thickness of the extending part, and achieves the following effects. Since a part of the extended existing portion is reinforced by the stopper portion, it is easy to deepen the cut in the edge portion. Therefore, it is easy to cut off the edge. That is, when the sealing paper is peeled off, it is possible to suppress the case where the extraction port is not formed or the case where it is not formed into the desired shape. In addition, even if the cut marks on the edge are deepened, it is possible to prevent the cut-off part from shifting or deviating during manufacturing (before the sealing paper is stuck to the main body of the take-out surface). Therefore, the extraction port can be stably formed into a desired shape. In addition, the airtightness of the package is maintained, and the intrusion of foreign matter can be suppressed. In addition, since the cut-off portion can be cut off along the pair of extended existing portions starting from the curve of the edge portion, it is easy to smoothly cut the cut-off portion. Here, assuming that the stopper is provided at the part of the edge part that obliquely intersects with the direction in which the sealing paper is torn off, the stopper distributes the force when tearing off the sealing paper to a direction different from the direction of tearing off the sealing paper. Orientation, the body of the take-out surface may be broken. On the other hand, according to this structure, because the stop portion is in the edge portion of the extending portion extending in the direction in which the sealing paper is torn off, the force when tearing off the sealing paper can be allowed to run to the stop portion. Existing part (cut) downstream of the extension. Therefore, when the sealing paper is torn off, the breakage of the main body of the take-out surface can be suppressed.

According to the packaging body described in (12) of the present invention, the edge portion is provided with: a first curved portion, which is provided on the side of the sealing paper from which the peeling of the sealing paper begins than the pair of extended portions, as the direction and the tearing A convex arc-shaped curve is formed on the opposite side of the lower sealing paper; a pair of extending portions are connected to both ends of the first curve portion and have a length shorter than the radius of curvature of the first curve portion; and a pair The second curved part of is set on the side where the sealing paper is torn off more than the pair of extended parts, and forms a convex arc toward the outside of the direction orthogonal to the direction in which the sealing paper is torn off. A radius of curvature larger than the radius of curvature of the first curved portion achieves the following effects. Since the cut-off portion can be cut off along the pair of extended portions and the pair of second curved portions from the first curved portion of the edge portion as a starting point, it is easy to smoothly cut the cut-off portion. In addition, because the radius of curvature of the first curved portion is smaller than that of the pair of second curved portions (because the end on the side where the sealing paper from the outlet is torn off becomes a narrow portion), the opening at the outlet can be enlarged. Passage resistance of the sheet at the end of the sealing paper on the side where tearing off starts. For example, when the sheets are taken out one by one from the take-out port, it is easy to separate the sheets on the preceding side and the subsequent side.

According to the packaging body described in (13) of the present invention, the edge portion is further provided with a pair of connecting portions, which are formed in a convex arc shape toward the inner side of the direction orthogonal to the direction in which the sealing paper is torn off, and a pair of connecting portions are successively formed. The end of the sealing paper of the extended portion and the end of the sealing paper of the pair of second curved portions on the side where the tearing of the sealing paper starts to achieve the following effects. Since the cut-off portion can be cut off along the pair of extended portions, the pair of connecting portions, and the pair of second curved portions starting from the first curved portion of the edge portion, it is easy to smoothly remove the cut-off portion. Was cut away.

According to the packaging body described in (14) of the present invention, since the stopper does not have a cut mark, the following effects are achieved. Compared with the case where the stopper portion has a cut mark, it is easier to reinforce a part of the extended existing portion by the stopper portion, and therefore, it is easier to further deepen the cut mark of the edge portion. In addition, because the stopper does not need to be cut during manufacturing, the productivity is excellent.

According to the package described in (15) of the present invention, since the edge portion is formed in a point-symmetrical shape with the center in the direction in which the sealing paper is torn off as the rotation center, the following effects are achieved. It is also easy to cut away the cut-off part in either the case where the direction of tearing off the sealing paper is from one of the directions of tearing off the sealing paper to the other direction and the opposite direction. In addition, when the direction in which the sealing paper is torn off and the conveying direction during manufacturing are opposite to each other, it is easy to cut the product from the cut-off part, and it is possible to prevent the cut-off part from being caused by wind and other factors during manufacturing. Circumstances of deviation or deviation.

<The first embodiment>

Hereinafter, the first embodiment of the present invention will be described with reference to the drawings. In each drawing, the same symbol is indicated for the same structure. In the first embodiment, a wet tissue (liquid-containing sheet) will be described as an example of a sheet for housing the package. For example, wet tissues are rectangular in plan view. Wet wipes are those made by impregnating non-woven fabrics, tissues, etc. with liquids (for example, liquids mixed with alcohols, antibacterial agents, preservatives, fragrances, etc. in water).

＜Package body＞ As shown in FIG. 1, the package 1 includes a packaging bag 10 and a sealing paper 20. The packaging bag 10 has a bag shape of a size capable of accommodating a laminate of a plurality of wet tissues 2 stacked. The packaging bag 10 is formed of a flexible film material having air-tightness and water resistance.

For example, the packaging bag 10 is joined by sequentially layering polyethylene terephthalate (PET) film, aluminum foil, a so-called sealing material, etc. from the surface (outside). The laminated film is formed. For example, for the laminated film, aluminum, silica, alumina, etc. are vapor-deposited on the PET film, and a heat-sealable film is superimposed on the inner surface.

The packaging bag 10 includes a film-like take-out surface body 11. The take-out noodle main body 11 is a surface part that can be taken out on the side of the wet tissue 2 contained in the packaging bag 10. For example, the thickness of the take-out surface main body 11 is several tens of μm. In a plan view, the take-out surface main body 11 has a rectangular shape larger than the outer shape of the wet tissue 2.

As shown in FIG. 4, the take-out surface body 11 is a laminated sheet of a plurality of layers 11a and 11b. For example, the take-out surface main body 11 has a first layer 11a located on the side of the sealing paper 20 in the thickness direction of the take-out surface main body 11, and a second layer 11b located on the opposite side of the sealing paper 20 in the thickness direction of the take-out surface main body 11 . For example, the take-out surface main body 11 has a PET film on the first layer 11a, and has a vapor-deposited film of aluminum or the like on the second layer 11b.

As shown in FIG. 2, the take-out surface body 11 has an edge portion 13 (refer to FIG. 3) along the outer edge of the take-out opening 12 of the wet tissue 2 contained in the packaging bag 10, and an outer edge portion 13 along the outer shape of the edge portion 13 Cut the part 14 (refer to FIG. 3). The edge portion 13 has a half-cut cut 15 formed along the outer shape of the cut-off portion 14 (refer to FIG. 4 ). In addition, the illustration of the cut-off part 14 is omitted in FIG. 4.

As shown in FIG. 1, the sealing paper 20 is stuck to the take-out surface body 11. The sealing paper 20 covers the cut-off part 14 (refer to FIG. 3). In a plan view, the sealing paper 20 has a larger outer shape than the cut-off portion 14. The sealing paper 20 has an adhesive layer (not shown) on the side of the cut-off part 14. The sealing paper 20 is affixed to the take-out surface body 11 so as to be peelable repeatedly.

The sealing paper 20 has a pinching part 21 that is pinched when the sealing paper 20 is torn off. For example, the pinching part 21 has a size that a user can pinch with a thumb and index finger. The pinch portion 21 has a triangle-shaped mark indicating the direction in which the sealing paper 20 is torn off (hereinafter also referred to as "peeling direction DP").

As shown in FIG. 2, the take-out port 12 is formed in a shape extending in the long axis direction DL along the direction in which the sealing paper 20 is torn off. In a plan view, the take-out port 12 has an oblong shape with the long axis along the peeling direction DP. Before the sealing paper 20 is torn off, the take-out port 12 is not open. That is, before tearing off the sealing paper 20, the edge portion 13 and the cut-off portion 14 are joined together (refer to FIG. 3). When the sealing paper 20 is torn off along the peeling direction DP, the cut-off portion 14 is cut along the cut 15 to open the take-out port 12. If the take-out port 12 is opened, a part of the wet tissue 2 contained in the packaging bag 10 is exposed.

＜Edges＞ As shown in FIG. 3, the edge part 13 forms a point symmetrical shape with the center C of the long axis direction DL (peeling direction DP) as a rotation center. The edge portion 13 includes a pair of extended portions 30, a thin portion 31, and a pair of connecting portions 32. The edge portion 13 has a half-cut cut 15 formed along the outer shape of the cut-off portion 14 (refer to FIG. 4 ). For example, the depth of the cut 15 is 40% to 70% of the thickness of the take-out surface body 11. For example, when the take-out surface body 11 has a PET film on the first layer 11a, and when the second layer 11b has a vapor-deposited film of aluminum or the like, it is better to cut at least the first layer 11a. In the present embodiment, the cut 15 is formed on the side of the sealing paper 20 of the take-out surface main body 11 and is not formed on the side opposite to the sealing paper 20 of the take-out surface main body 11. For example, the length of the long axis direction DL of the edge part 13 is 40 mm-60 mm.

＜Extended presence part＞ The extended portion 30 has a cut that extends along the peeling direction DP. For example, the depth of the cut 15 of the extended portion 30 is 40% to 50% of the thickness of the take-out surface main body 11. As shown in FIG. 4, the cut 15 of the extended portion 30 is formed in the layer 11a except for the last layer 11b among the plurality of layers 11a and 11b. The "last layer" refers to the last layer counted from the side where the cut 15 is formed (for example, the side of the lower knife) on the main body 11 of the take-out surface. In this embodiment, the cut 15 of the extended portion 30 is formed on the first layer 11a except for the last second layer 11b, counting from the sealing paper 20 side of the two layers 11a and 11b. That is, the cut 15 of the extended portion 30 is formed only in the first layer 11a among the plurality of layers 11a and 11b. The "first layer" refers to the first layer counted from the side where the cut 15 is formed (for example, the side of the lower knife) on the main body 11 of the take-out surface.

As shown in FIG. 3, the extended portion 30 is formed in a convex arc shape on the outside in a direction orthogonal to the long axis direction DL (hereinafter also referred to as "short axis direction DS") when viewed in plan. The extended portion 30 is located most outside the short axis direction DS in the center position of the peeling direction DP. Hereinafter, in the peeling direction DP, the side on which the peeling of the sealing paper 20 starts is referred to as "the upstream side of the peeling direction DP", and the peeling direction DP is on the opposite side of the upstream side of the peeling direction DP, that is, the peeling of the sealing paper 20 ends. The side is called "the downstream side of the peeling direction DP". The pair of extending portions 30 are connected to each other on the downstream side in the peeling direction DP.

The extended portion 30 has a radius of curvature R1 that is larger than the radius of curvature R2 of the thin portion 31 at the center of the peeling direction DP. The distance between the center C in the major axis direction DL of the edge portion 13 and the outer end of the extension portion 30 in the minor axis direction DS (the outermost part in the minor axis direction DS) is greater than the radius of curvature R2 of the thin portion 31 Bigger. For example, the distance between the outer ends of the pair of extending portions 30 in the short axis direction DS is 10 mm to 30 mm.

＜Thin-walled part＞ As shown in FIG. 4, the thin-walled portion 31 has a cut 15 deeper than the extended portion 30. For example, the depth of the cut 15 of the thin portion 31 is 60% to 70% of the thickness of the take-out surface main body 11. The cut 15 of the thin portion 31 is formed in each of the plural layers 11a and 11b. Specifically, the cut 15 of the thin-walled portion 31 penetrates the first layer 11a of the plurality of layers 11a and 11b to the last layer 11b, and is also formed in the last layer 11b. The cut 15 of the thin-walled portion 31 is that the last layer 11b does not penetrate. In addition, in FIG. 4, in order to easily understand the difference in the depth of the cut 15 of the thin portion 31 and the extended portion 30, the cut 15 is exaggerated and illustrated.

As shown in FIG. 3, the thin-walled portion 31 is provided on the upstream side in the peeling direction DP relative to the pair of extended portions 30. The thin-walled portion 31 is connected via the connecting portion 32 and the end on the upstream side in the peeling direction DP of the pair of extending portions 30. The thin portion 31 forms a convex arc shape toward the side opposite to the peeling direction DP in a plan view. In a plan view, the thin portion 31 starts from the outer end on the opposite side to the peeling direction DP, and forms a convex curved shape outward toward the downstream side of the peeling direction DP and the outer side in the minor axis direction DS. For example, the radius of curvature R2 of the thin portion 31 is 2 mm to 4 mm.

＜Connecting part＞ The connecting portion 32 is arranged between the extended portion 30 and the thin portion 31 in the long axis direction DL. A pair of connecting portions 32 are connected in the peeling direction DP to the ends on the side of the thin portion 31 (the end on the upstream side of the peeling direction DP) and the ends of the thin portion 31 (the peeling direction DP) of the pair of extending portions 30, respectively. The end on the downstream side).

As shown in FIG. 4, the depth of the connecting portion 32 from the side of the thin-walled portion 31 toward the side cut 15 of the extending portion 30 gradually becomes shallow. The depth of the cut 15 of the connecting portion 32 is the depth of the cut 15 at the end on the downstream side in the peeling direction DP of the thin-walled portion 31 and the cut 15 at the end on the upstream side of the extending portion 30 in the peeling direction DP. Make changes between the depths. For example, the depth of the cut of the connecting portion 32 is changed within a range of 50% to 60% of the thickness of the take-out surface body 11.

＜Formation method of edge part＞ As shown in FIG. 5, the method of forming the edge portion 13 is a conveying device 50 using a long strip-shaped base material 40. The conveying device 50 includes a pair of conveying rollers 51 and 52 (the first roller 51 and the second roller 52) facing each other. The base material 40 has a plurality of take-out surface body forming portions 41 (portions for forming the take-out surface body 11) arranged in the conveying direction DT. The edge portion 13 of the take-out surface body 11 is formed by using a pair of conveying rollers 51 and 52 while carrying a long strip-shaped base material 40 as a conveying side.

On the surface of the first roller 51, a metal mold 55 having a blade 56 along the outer shape of the edge portion 13 is attached. For example, the height of the blade 56 is 0.1 mm to 0.9 mm. The blade 56 is a part corresponding to the thin portion 31 of the edge part 13 which is higher than the other parts.

For example, if the pair of conveying rollers 51 and 52 are rotated, the base material 40 is conveyed in one direction (moved in the conveying direction DT). In the process of conveying the base material 40, the blade 56 of the metal mold 55 sinks into the take-out surface body forming portion 41 to form the edge portion 13. As the blade 56 of the metal mold 55 becomes higher as described above, the blade 56 that is larger than the other locations in the portion corresponding to the thin portion 31 of the edge portion 13 sinks. In the example of FIG. 5, the long axis direction DL of the edge portion 13 is parallel to the conveying direction DT of the base material 40.

<Effects> As described above, the packaging body 1 of the above embodiment is a packaging body 1 that can store wet tissues 2 and is provided with a film-like take-out surface body 11 having: wet tissues that can be taken out and housed in the packaging body 1 along the line 2. The edge portion 13 of the outer edge of the take-out port 12 and the cut-off portion 14 along the outer shape of the edge portion 13; and the sealing paper 20, which is adhered to the take-out surface body 11, covering the cut-off portion 14 and the edge portion 13 It includes: a pair of extended portions 30 having cuts 15 extending along the peeling direction DP; and a thin-walled portion 31 provided on the upstream side of the pair of extended portions 30 in the peeling direction DP, The ends of the pair of extension portions 30 are connected to each other, have a convex arc shape toward the side opposite to the peeling direction DP, and have a cut 15 deeper than the extension portion 30.

According to this structure, since the thin-walled portion 31 of the edge portion 13 is deeper than the cut 15 of the extended portion 30, the thin-walled portion 31 of the edge portion 13 can be used as a starting point to reduce the force when the cut-off portion 14 is cut away. When the cut-off portion 14 is once cut off in the thin-walled portion 31, it is cut off along the pair of extended existing portions 30 following the cut-off of the thin-walled portion 31. Therefore, compared with the case where the cut 15 is formed with the same depth along the outer shape of the cut-off portion 14, the cut-off portion 14 is easily cut off. That is, when the sealing paper 20 is peeled off, it is possible to suppress the case where the outlet 12 is not formed or the case where it is not formed into a desired shape. In addition, since it is easy to make the cut 15 of the extended portion 30 shallow, even if the cut 15 of the thin portion 31 is deepened, it can be suppressed during manufacturing (sticking the sealing paper 20 to the take-out surface body 11). Before), when the cut-off portion 14 is offset or deviated. Therefore, the extraction port 12 can be stably formed into a desired shape. In addition, the airtightness of the package 1 can be maintained. Therefore, while suppressing the intrusion of foreign matter, the drying of the wet tissue 2 can be suppressed.

According to the above embodiment, because the edge portion 13 is further provided with a pair of connecting portions 32, a pair of the ends on the side of the thin portion 31 and the both ends of the thin portion 31 of the extending portion 30 are connected successively in the peeling direction DP. The depth of the cut 15 from the side of the thin-walled portion 31 toward the side of the extending portion 30 gradually becomes shallow, and the following effects are achieved. Since there is a connecting portion 32 between the thin-walled portion 31 and the extended portion 30, the difference in the depth of the cut 15 between the thin-walled portion 31 and the extended portion 30 gradually decreases. Therefore, the cut-off portion 14 can be smoothly cut off along the pair of connecting portions 32 and the pair of extending portions 30 starting from the thin-walled portion 31 of the edge portion 13. Therefore, it is easier to cut away the cut-off portion 14.

According to the above-mentioned embodiment, the cut 15 is formed on the side of the sealing paper 20 of the take-out surface body 11, and is not formed on the side opposite to the sealing paper 20 of the take-out surface body 11, and the following effects are achieved. Compared with the case where the cut 15 is formed on the side opposite to the sealing paper 20 of the take-out surface body 11, the airtightness of the package 1 can be maintained more effectively.

According to the above-mentioned embodiment, since the take-out surface main body 11 is a laminated sheet of a plurality of layers 11a and 11b, the following effects are achieved. The main body 11 of the take-out surface can be provided with multiple functions, such as a layer that does not easily pass moisture and a layer that is easy to develop color.

According to the above embodiment, the cut 15 of the extended portion 30 is formed in the layer 11a of the plurality of layers 11a, 11b except for the last layer 11b, and the cut 15 of the thin-walled portion 31 penetrates the first layer of the plurality of layers 11a, 11b 11a, and achieve the following effects. Since the cut 15 of the extending portion 30 is not formed in the last layer 11b, the cut portion 14 can be easily cut away from the take-out surface body 11 while maintaining the airtightness of the package body 1.

According to the above embodiment, since the cut 15 of the thin-walled portion 31 penetrates the first layer 11a of the plurality of layers 11a and 11b to the last layer 11b, which is also formed in the last layer 11b, the following effects are achieved. Since the thin-walled portion 31 has a cut mark to the last layer 11b of the laminate, the cut-off portion 14 can be cut away from the take-out surface body 11 while suppressing interlayer peeling.

<Modifications of the first embodiment> In addition, in the above-mentioned embodiment, although the sheet|seat body was demonstrated using the example of the wet tissue 2, it is not limited to this. For example, the sheet may be a sheet other than the wet tissue 2 such as a wet sheet and a dry sheet.

In the above-mentioned present embodiment, although the cut 15 is formed on the side of the sealing paper 20 of the take-out surface main body 11, and is not formed on the side opposite to the sealing paper 20 of the take-out surface main body 11 as an example, it is not limited to this. For example, as shown in FIG. 6, the cut 15 may be formed on the side opposite to the sealing paper 20 of the take-out surface body 11 instead of being formed on the side of the sealing paper 20 of the take-out surface body 11. According to this structure, compared with the case where the cut 15 is formed on the side of the sealing paper 20 of the take-out surface main body 11 (see FIG. 4), the cut-off portion 14 is easily cut from the take-out surface main body 11 when the sealing paper 20 is torn off.

In the above-mentioned embodiment, although the take-out surface main body 11 is a laminated sheet with two layers 11a and 11b as an example, it is not limited to this. For example, the take-out surface main body 11 may be a single layer or a laminated sheet of three or more layers.

In the above-mentioned embodiment, although the cut 15 of the extended portion 30 is formed on the layer 11a other than the last layer 11b among the plurality of layers 11a and 11b as an example, it is not limited to this. For example, the cut 15 of the extending portion 30 may be formed to the last layer 11b among the plurality of layers 11a and 11b. According to this structure, the cut 15 extending the existing portion 30 is formed in all of the plurality of layers 11a and 11b. Therefore, the cut-off portion 14 can be easily cut away from the take-out surface main body 11 while suppressing interlayer peeling.

In the above-mentioned embodiment, although the example in which the cut 15 of the thin-walled part 31 is formed in each of the multiple layers 11a, 11b was demonstrated, it is not limited to this. For example, as shown in FIG. 7, the cut 15 of the thin-walled portion 31 is formed only in the first layer 11a among the plural layers 11a and 11b. That is, the cut 15 of the extended portion 30 and the cut 15 of the thin portion 31 may be formed only in the first layer 11a of the plurality of layers 11a and 11b. According to this structure, since there is no cut 15 in the last layer 11b (the layer closest to the wet tissue 2), the liquid will not penetrate into the interlayer of the laminate, and interlayer peeling will not easily occur. That is, because the cut 15 is on the side of the sealing paper 20 of the take-out surface body 11, the problem of liquid infiltration from the wet tissue 2 to the cut 15 does not occur.

In the example of FIG. 7, although the cut 15 is on the side of the sealing paper 20 of the take-out surface body 11, the cut 15 of the extended portion 30 and the cut 15 of the thin portion 31 are formed only to the plural layers 11a, 11b The example of the first layer 11a in the first layer is illustrated, but it is not limited to this. For example, as shown in FIG. 8, when the cut 15 is located on the opposite side of the sealing paper 20 of the take-out surface body 11, the cut 15 of the extended portion 30 and the cut 15 of the thin portion 31 may be formed only in plural. The first layer 11a among the layers 11a, 11b. In addition, in the example of FIG. 8, the arrangement of the first layer and the last layer are opposite to the example of FIG. 7 (for example, the direction of the cutting edge). According to this structure, since only the first layer 11a (the layer closest to the wet tissue 2) has the cut 15, the liquid does not penetrate between the layers of the laminate, and it is difficult to produce interlayer peeling.

In the above-mentioned embodiment, although the shape of the extraction port 12 extending in the long axis direction DL along the direction in which the sealing paper 20 is torn off is taken as an example for description, it is not limited to this. For example, the take-out port 12 may be formed in a shape extending in a direction intersecting the long axis direction DL of the direction in which the sealing paper 20 is torn off. In a plan view, the take-out port 12 may have an oblong shape with the long axis along the peeling direction DP. Or when viewed from a top view, the take-out port 12 may also have a perfect circular shape.

In the above-mentioned embodiment, although the example of the package 1 which accommodates the wet tissue 2 (sheet body) was demonstrated, it is not limited to this. For example, the present invention can also be applied to containers other than the package 1 of the sheet (for example, a container for juice in a paper package).

<Second Embodiment> Hereinafter, the second embodiment of the present invention will be described with reference to the drawings. In the second embodiment, the same symbol is indicated for the same structure as in the first embodiment. In each drawing, the same symbol is indicated for the same structure. In the second embodiment, a wet tissue (liquid sheet containing) will be described as an example of a sheet for storing the package. For example, wet tissues are rectangular in plan view. Wet wipes are those made by impregnating non-woven fabrics, tissues, etc. with liquids (for example, liquids mixed with alcohols, antibacterial agents, preservatives, fragrances, etc. in water).

＜Package body＞ As shown in FIG. 9, the package 2001 includes a packaging bag 10 and a sealing paper 20. The packaging bag 10 has a bag shape of a size capable of accommodating a laminate of a plurality of wet tissues 2 stacked. The packaging bag 10 is formed of a flexible film material having air-tightness and water resistance.

For example, the packaging bag 10 is joined by sequentially layering polyethylene terephthalate (PET) film, aluminum foil, a so-called sealing material, etc. from the surface (outside). The laminated film is formed. For example, for the laminated film, aluminum, silica, alumina, etc. are vapor-deposited on the PET film, and a heat-sealable film is superimposed on the inner surface.

The packaging bag 10 includes a film-like take-out surface body 2011. The take-out noodle main body 2011 is a surface part on the side of the wet tissue 2 housed in the packaging bag 10 that can be taken out. For example, the thickness of the take-out surface body 2011 is several tens of μm. In a plan view, the take-out surface main body 2011 has a larger rectangular shape than the wet tissue 2.

As shown in FIG. 12, the take-out surface body 2011 is a laminated sheet of a plurality of layers 11a and 11b. For example, the take-out surface main body 2011 has: a first layer 11a located on the side of the sealing paper 20 in the thickness direction of the take-out surface main body 2011, and a second layer 11b located on the opposite side of the sealing paper 20 in the thickness direction of the take-out surface main body 2011 . For example, the take-out surface body 2011 has a PET film on the first layer 11a, and has a vapor-deposited film of aluminum or the like on the second layer 11b.

As shown in FIG. 10, the take-out surface body 2011 has an edge portion 2013 (refer to FIG. 11) along the outer edge of the take-out opening 2012 of the wet tissue 2 contained in the packaging bag 10, and an outer shape along the edge portion 2013 Cut the part 14 (refer to FIG. 11). In the edge portion 2013, a cut 15 that is half-cut is formed along the outer shape of the cut-off portion 14 (see FIG. 12). In addition, the illustration of the cut-off part 14 is omitted in FIG. 12.

As shown in FIG. 9, the sealing paper 20 is stuck to the take-out surface body 2011. The sealing paper 20 covers the cut-off part 14 (refer to FIG. 11). In a plan view, the sealing paper 20 has a larger outer shape than the cut-off portion 14. The sealing paper 20 has an adhesive layer (not shown) on the side of the cut-off part 14. The sealing paper 20 is affixed to the take-out surface body 2011 so as to be peelable repeatedly.

The sealing paper 20 has a pinching part 21 that is pinched when the sealing paper 20 is torn off. For example, the pinching part 21 has a size that a user can pinch with a thumb and index finger. The pinch portion 21 has a triangle-shaped mark indicating the direction in which the sealing paper 20 is torn off (hereinafter also referred to as "peeling direction DP").

As shown in FIG. 10, the take-out port 2012 is formed in a shape extending in the long axis direction DL along the direction in which the sealing paper 20 is torn off. Before the sealing paper 20 is torn off, the take-out port 2012 is not open. That is, before tearing off the sealing paper 20, the edge portion 2013 and the cut-off portion 14 are connected together (refer to FIG. 11). When the sealing paper 20 is torn off along the peeling direction DP, the cut-off portion 14 is cut along the cut 15 to open the take-out port 2012. If the take-out port 2012 is opened, a part of the wet tissue 2 contained in the packaging bag 10 will be exposed.

＜Edges＞ As shown in FIG. 11, the edge part 2013 forms a point symmetrical shape with the center C of the long axis direction DL (peeling direction DP) as a rotation center. The edge portion 2013 includes a first curved portion 2030, a pair of extending portions 2031, a stopper portion 2032, a pair of second curved portions 2033, and a pair of connecting portions 2034. In the edge portion 2013, except for the stop portion 2032 (the first curved portion 2030, a pair of extended portions 2031, a pair of second curved portions 2033, and a pair of connecting portions 2034 along the cut-off portion 14 The outer shape is formed with a half-cut cut 15 (see FIG. 12). For example, the length of the edge portion 2013 in the major axis direction DL is 40 mm to 60 mm.

The cut 15 is formed with the same depth along the outer shape of the cut-off part 14 (refer to FIG. 12). For example, the depth of the cut 15 is 40% to 70% of the thickness of the take-out surface body 2011. For example, when the take-out surface body 2011 has a PET film on the first layer 11a and the second layer 11b has a vapor-deposited film of aluminum or the like, at least the first layer 11 is preferably cut. In the present embodiment, the cut 15 is formed on the first layer 11a on the side of the sealing paper 20 of the take-out surface body 2011, and is not formed on the second layer 11b on the opposite side of the sealing paper 20 of the take-out surface main body 2011. The cut 15 is formed in layers other than the last layer 11b among the plurality of layers 11a and 11b. In the present embodiment, the cut 15 is formed in the first layer 11a except for the last second layer 11b from the side of the sealing paper 20 among the two layers 11a and 11b.

＜The first curve part＞ As shown in FIG. 11, the first curved portion 2030 forms a convex arc shape outward in the long axis direction DL in a plan view. The first curved portion 2030 is formed in a convex arc shape toward each of the side where the tearing off starts and the side where the tear off ends of the sealing paper 20. Hereinafter, in the peeling direction DP, the side on which the peeling of the sealing paper 20 starts is referred to as "the upstream side of the peeling direction DP", and the peeling direction DP is on the opposite side of the upstream side of the peeling direction DP, that is, the peeling of the sealing paper 20 ends. The side is called "the downstream side of the peeling direction DP". In a plan view, the first curved portion 2030 starts from the end of the sealing paper 20 on the side from which the tearing off begins, and goes toward the downstream side of the peeling direction DP, and is located in a direction orthogonal to the long axis direction DL (hereinafter also referred to as "short" The axial direction DS".) is formed into a convex curved shape toward the outside. The first curved portion 2030 is provided on both sides of the edge portion 2013 in the long axis direction DL. For example, the radius of curvature R1 of the first curved portion 2030 is 2 mm to 4 mm.

＜Extended presence part＞ Both ends of the extended portion 2031 and the first curved portion 2030 are connected one after another. The extended portion 2031 extends along the peeling direction DP. The extended portion 2031 linearly extends from the end on the downstream side of the peeling direction DP of the first curved portion 2030 toward the downstream side of the peeling direction DP in a plan view. The pair of extended portions 2031 are provided substantially parallel to each other in the major axis direction DL.

"Approximately parallel" refers to a case where the pair of extended portions 2031 are substantially parallel to each other within the allowable range of the design error (dimension error) of the packaging bag 10. The term “substantially parallel” includes a case where a pair of extended portions 2031 inclined obliquely in a range of ±5° with respect to the long axis of the take-out port 2012. In addition, "substantially parallel" includes a case where a pair of extended portions 2031 are completely parallel to each other. In addition, "substantially parallel" refers to the case where the pair of extended portions 2031 are inclined obliquely with respect to the peeling direction DP within a range that can suppress the breakage of the take-out surface main body 2011 when the sealing paper 20 is torn off.

The pair of extending portions 2031 are provided on both sides of the edge portion 2013 in the long axis direction DL. The extended portion 2031 has a length shorter than the radius of curvature R1 of the first curved portion 2030. For example, the length of the extended portion 2031 is 1 mm to 2 mm. For example, it is desirable that the length of the extended portion 2031 is approximately half of the radius of curvature R1 of the first curved portion 2030.

＜Stopping part＞ As shown in FIG. 12, the stopper portion 2032 is provided in the middle of the extending portion 2031. The stopper portion 2032 is a thicker portion than the thickness of the extended portion 2031. In this embodiment, the stopper 2032 does not have the cut 15. The stopper 2032 has the same thickness as the take-out surface main body 2011. As shown in FIG. 11, the stoppers 2032 are provided on both sides of the edge portion 2013 in the long axis direction DL. One stopper portion 2032 is provided in each extended portion 2031.

＜Second curve part＞ The second curved portion 2033 is provided on the opposite side to the first curved portion 2030 in the major axis direction DL. The second curved portion 2033 is provided on the downstream side of the peeling direction DP relative to the first extending portion 30. The second curved portion 2033 is provided at the center of the edge portion 2013 in the long axis direction DL. The second curved portion 2033 forms a convex arc shape outward in the short-axis direction DS in a plan view. The second curved portion 2033 is located most outside the short axis direction DS in the center position of the peeling direction DP.

The second curved portion 2033 has a radius of curvature R2 that is larger than the radius of curvature R1 of the first curved portion 2030. The distance between the center C of the major axis direction DL of the edge portion 2013 and the outer end of the minor axis direction DS of the second curve portion 2033 (the outermost part in the minor axis direction DS) is greater than the curvature of the first curve portion 2030 The radius R1 is larger. For example, the distance between the outer ends of the pair of second curved portions 2033 in the minor axis direction DS is 10 mm to 30 mm.

＜Connecting part＞ The connecting portion 2034 is arranged between the extended portion 2031 and the second curved portion 2033 in the long axis direction DL. The connecting portion 2034 forms a convex arc shape inward in the short-axis direction DS in a plan view. A pair of connecting portions 2034 are respectively connected in the long axis direction DL and the end on the opposite side of the first curved portion 2030 of the pair of extending portions 2031 (the end on the downstream side of the peeling direction DP), and the pair of second curved portions 2033 The end on the side of the first curved portion 2030 (the end on the upstream side in the peeling direction DP). The pair of connecting portions 2034 are provided on both sides of the edge portion 2013 in the long axis direction DL. For example, the radius of curvature Rc of the connecting portion 2034 is 1 mm to 2 mm. For example, it is desirable that the radius of curvature Rc of the connecting portion 2034 is set to be the same as the length of the extended portion 2031.

＜Formation method of edge part＞ As shown in FIG. 13, the formation method of the edge part 2013 uses the conveying apparatus 50 which conveys the base material 40 of a long strip|belt shape. The conveying device 50 includes a pair of conveying rollers 51 and 52 (the first roller 51 and the second roller 52) facing each other. The base material 40 has a plurality of take-out surface main body forming portions 41 (a portion for forming the take-out surface main body 2011) arranged in the conveying direction DT. The edge portion 2013 of the take-out surface main body 2011 is formed by using a pair of conveying rollers 51 and 52 while using a long strip-shaped base material 40 as a conveying side.

On the surface of the first roller 51, a metal mold 55 having a blade 56 along the outer shape of the edge portion 2013 is attached. For example, the height of the blade 56 is 0.1 mm to 0.9 mm. The metal mold 55 does not have a blade 56 at a location corresponding to the stop portion 2032 of the edge portion 2013.

For example, if the pair of conveying rollers 51 and 52 are rotated, the base material 40 is conveyed in one direction (moved in the conveying direction DT). In the process of conveying the base material 40, the blade 56 of the metal mold 55 sinks into the take-out surface body forming portion 41 to form an edge portion 2013. In the example shown in the figure, the major axis direction DL of the edge portion 2013 is parallel to the conveyance direction DT of the base material 40.

<Effects> As described above, the packaging body 2001 of the second embodiment is a packaging body 2001 that can contain wet tissues 2 and is provided with: a film-like take-out surface body 2011, which has: the packaging body 2001 that can be taken out along The edge portion 2013 of the outer edge of the take-out port 2012 of the wet tissue 2 and the cut-off portion 14 along the outer shape of the edge portion 2013; and the sealing paper 20, which is adhered to the take-out surface body 2011, covers the cut-off portion 14, and the edge The portion 2013 includes a pair of extending portions 2031 having a cut 15 that are connected to both ends of a curve convex on the side opposite to the peeling direction DP and extend along the peeling direction DP; and a stop portion 2032, which It is provided in the middle of the extended portion 2031 and is thicker than the thickness of the extended portion 2031.

According to this structure, since a part of the extending portion 2031 is reinforced by the stopper portion 2032, the cut 15 of the edge portion 2013 is easily deepened. Therefore, it is easy to cut off the edge portion 2013. That is, when the sealing paper 20 is peeled off, the case where the extraction port 2012 is not formed or the case where it is not formed into a desired shape can be suppressed. In addition, even if the cut 15 of the edge portion 2013 is deepened, it is possible to prevent the cut-off portion 14 from shifting or deviating during manufacturing (before the sealing paper 20 is stuck to the take-out surface body 2011). Therefore, the extraction port 2012 can be stably formed into a desired shape. In addition, the airtightness of the package 2001 can be maintained. Therefore, while suppressing the intrusion of foreign matter, the drying of the wet tissue 2 can be suppressed. In addition, since the cut-off portion 14 can be cut off along the pair of extended existing portions 2031 starting from the curve of the edge portion 2013, it is easy to cut off the cut-off portion 14 smoothly. Here, supposing that the stopper 2032 is provided at a portion obliquely crossing the peeling direction DP in the edge portion 2013, the stopper 2032 distributes the force when tearing off the sealing paper 20 to a direction different from the peeling direction DP. The removal surface body 2011 may be broken. On the other hand, according to this structure, since the stopper portion 2032 is located in the middle of the extended portion 2031 extending along the peeling direction DP in the edge portion 2013, the force when tearing off the sealing paper 20 can be allowed to run to the fixed portion. The extension part 2031 (notch 15) downstream of 2032 exists. Therefore, when the sealing paper 20 is torn off, it is possible to suppress the breakage of the take-out surface main body 2011.

According to the second embodiment described above, since the stopper 2032 does not have the cut 15, the following effects are achieved. Compared with the case where the stopper 2032 has the cut 15, it is easier to reinforce a part of the extended existing portion 2031 by the stopper 2032, so it is easier to further deepen the cut 15 of the edge portion 2013. In addition, since the stop portion 2032 does not need to be cut at the time of manufacturing, the productivity is excellent.

According to the second embodiment described above, the edge portion 2013 is formed in a point-symmetrical shape with the center C of the peeling direction DP as the rotation center, and the following effects are achieved. Even if the peeling direction DP is from one direction of the peeling direction DP to the other direction, and the case where it is the opposite direction, it is easy to cut away the cut-off part 14. In addition, when the peeling direction DP and the conveying direction DT at the time of manufacture are opposite to each other, it is easy to cut the cut-off part 14 in the product, and it is possible to prevent the cut-off part 14 from being caused by wind and other factors during manufacture.

For example, as shown in FIG. 16, the cut 15 may be formed on the side opposite to the sealing paper 20 of the take-out surface main body 2011 instead of being formed on the side of the sealing paper 20 of the take-out surface main body 2011. According to this structure, compared with the case where the cut 15 is formed on the side of the sealing paper 20 of the take-out surface main body 2011 (see FIG. 12), when the sealing paper 20 is torn off, the cut-off portion 14 is easily cut from the take-out surface main body 2011.

In the above second embodiment, although the take-out surface main body 2011 is a laminated sheet with two layers 11a and 11b as an example for description, it is not limited to this. For example, the take-out surface body 2011 may also be a single layer, or a laminated sheet of more than three layers.

In the above-mentioned second embodiment, although the cut 15 is formed in the layer 11a of the plurality of layers 11a and 11b except for the last layer 11b as an example, it is not limited to this. For example, as shown in FIG. 17, the cut 15 may be formed to the last layer 11b among the plurality of layers 11a and 11b. According to this structure, since the cut 15 is formed in all the layers of the plural layers 11a and 11b, the cut-off portion 14 can be easily cut away from the take-out surface main body 2011 while suppressing delamination between the layers.

In the second embodiment described above, although the example in which the stopper portion 2032 is provided at each extending portion 2031 is described, it is not limited to this.

The number of stoppers 2032 installed can be changed to any number in accordance with the required specifications.

In the second embodiment described above, although the edge portion 2013 is provided with: the first curved portion 2030, the pair of extending portions 2031, the pair of second curved portions 2033, and the pair of connecting portions 2034 as an example for description, it is not Limited to this. For example, the edge portion 2013 may not have a pair of second curved portions 2033 and a pair of connecting portions 2034. That is, the edge portion 2013 may be formed in a simple oblong shape (elliptical shape).

In the second embodiment described above, the shape of the extraction port 2012 extending in the long axis direction DL along the direction in which the sealing paper 20 is torn off is taken as an example for description, but it is not limited to this. For example, the take-out port 2012 may be formed in a shape extending in a direction crossing the direction in which the sealing paper 20 is torn off. In a plan view, the take-out port 2012 may have an oblong shape with the minor axis along the peeling direction DP. Or when viewed from a top view, the take-out port 2012 may also have a perfect circular shape. In other words, the edge portion 2013 only needs to include a pair of extended portions having the cut 15 that extend along the direction in which the sealing paper 20 is torn off. That is, the extended portion is not limited to linearly extending, but may also be curvilinearly extending.
