By including a thin portion which is provided on the first side and is continuous with the ends of the pair of extending portions, has a convex arc shape on the side opposite to the direction in which the seal is peeled off, and has a deeper cut than the extending portion. It has the following effects.
Since the thin-walled portion of the rim portion has a deeper cut than the extending portion, the force for separating the cut-off portion can be reduced starting from the thin-walled portion of the rim portion. Once the cut-off portion is cut off at the thin-walled portion, it is cut off along a pair of extending portions so as to follow the cut-off of the thin-walled portion. Therefore, it becomes easier to separate the cut portion as compared with the case where the cut is formed at a uniform depth along the outer shape of the cut portion. That is, it is possible to prevent the outlet from being formed when the seal is peeled off and the shape from not being formed as intended. In addition, since it is easy to make the cut in the extending part shallow, even if the cut in the thin part is deepened, it is possible to prevent the cut part from slipping or coming off during manufacturing (before attaching the seal to the take-out surface body).

By including a pair of extending portions having the above and a stopping portion provided in the middle of the extending portion and thicker than the thickness of the extending portion, the following effects can be obtained.
Since a part of the extending part is reinforced by the stopper part, it is easy to deepen the cut of the rim part. Therefore, it becomes easy to separate the rim portion. That is, it is possible to prevent the outlet from being formed when the seal is peeled off and the shape from not being formed as intended. In addition, even if the cut of the rim portion is deepened, it is possible to prevent the cut-off portion from being displaced or detached during manufacturing (before attaching the seal to the take-out surface main body). Therefore, the outlet can be stably formed in the intended shape.
In addition, the airtightness of the package can be maintained and the invasion of foreign matter can be suppressed.
In addition, since the separating portion is separated along the pair of extending portions starting from the curve of the rim portion, it is easy to smoothly separate the separating portion. Here, if the stopper is provided at a portion of the rim that diagonally intersects the direction in which the seal is peeled off, the force for peeling the seal is dispersed in a direction different from the direction in which the seal is peeled off at the stopper. As a result, the main body of the take-out surface may be torn. On the other hand, according to this configuration, since the stop portion is in the middle of the extending portion of the rim portion extending along the direction of peeling the seal, the force at the time of peeling the seal is applied to the extending portion downstream of the stop portion. You can escape to (cut). Therefore, it is possible to prevent the take-out surface main body from being torn when the seal is peeled off.

According to the package according to the above (12) of the present invention, the rim portion is provided on the side where the seal starts to be peeled off from the pair of extending portions, and has a convex arc shape on the side opposite to the direction in which the seal is peeled off.

A pair of second curved portions provided on the side at the end of peeling, forming an outwardly convex arc shape in a direction orthogonal to the direction in which the seal is peeled, and having a radius of curvature larger than the radius of curvature of the first curved portion. This has the following effects.
Since the separated portion is separated along the pair of extending portions and the pair of second curved portions starting from the first curved portion of the rim portion, the separated portion can be easily separated smoothly.
In addition, since 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 outlet seal starts to be peeled off becomes a narrow portion), the outlet seal starts to be peeled off. It is possible to increase the passage resistance of the sheet body at the end on the side of. For example, when the sheet bodies are sequentially taken out one by one from the outlet, it is easy to separate the preceding side and the succeeding sheet bodies one by one.

According to the package according to the above (13) of the present invention, the rim portion has an inwardly convex arc shape in the direction orthogonal to the direction in which the seal is peeled off, and the seal peeling end of the pair of extending portions is completed. The following effects can be obtained by further providing a pair of continuous portions having a side end and a pair of continuous portions having a side end at which the seal of the second curved portion starts to be peeled off.
Since the separating portion is separated along the pair of extending portions, the pair of continuous portions, and the pair of second curved portions starting from the first curved portion of the rim portion, the separated portion can be easily separated smoothly.

<First Embodiment>
Hereinafter, the first embodiment of the present invention will be described with reference to the drawings. In each figure, the same reference numerals are given to the same configurations. In the first embodiment, a wet tissue (liquid-containing sheet) will be described as an example of the sheet body contained in the package body. For example, a wet tissue has a rectangular shape in a plan view. Wet wipes are made by impregnating non-woven fabric, tissue paper, or the like with a liquid (for example, water mixed with alcohol, a disinfectant, a preservative, a fragrance, or the like).

<Packaging>
As shown in FIG. 1, the packaging body 1 includes a packaging bag 10 and a seal 20.
The packaging bag 10 has a bag shape having a size capable of accommodating a laminated body in which a plurality of wet tissues 2 are laminated. The packaging bag 10 is made of a flexible film material having airtightness and water resistance.

For example, the packaging bag 10 is formed of a laminated film in which a polyethylene terephthalate (PET) film, an aluminum foil, a so-called heat-sealing film called a sealant, and the like are laminated and bonded in order from the surface (outside). For example, the laminated film may be a PET film on which aluminum, silica, alumina, or the like is vapor-deposited, and a heat-sealing film is laminated on the inner surface.

The packaging bag 10 includes a film-shaped take-out surface main body 11. The take-out surface main body 11 is a planar portion on the side from which the wet tissue 2 housed in the packaging bag 10 is taken out. 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 main body 11 is a laminate of a plurality of layers 11a and 11b. For example, the take-out surface main body 11 has a first layer 11a on the side of the seal 20 in the thickness direction of the take-out surface main body 11 and a second layer 11b on the opposite side of the seal 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 a thin-film film such as aluminum on the second layer 11b.

As shown in FIG. 2, the take-out surface main body 11 has a mouth edge portion 13 (see FIG. 3) along the outer edge of the take-out port 12 from which the wet tissue 2 housed in the packaging bag 10 can be taken out, and the mouth edge portion 13. It has an outer shape separating portion 14 (see FIG. 3) along the outer shape. The rim portion 13 is formed with a cut 15 (see FIG. 4) that is half-cut along the outer shape of the cut-off portion 14. In FIG. 4, the disconnection portion 14 is not shown.

As shown in FIG. 1, the sticker 20 is attached to the take-out surface main body 11. The seal 20 covers the separating portion 14 (see FIG. 3). In plan view, the seal 20 has a larger outer shape than the detached portion 14. The seal 20 has an adhesive layer (not shown) on the side of the separating portion 14. The seal 20 is attached to the take-out surface main body 11 so as to be repeatedly peelable.

The seal 20 has a knob portion 21 that is picked when the seal 20 is peeled off. For example, the picking portion 21 has a size that allows the user to pick with the thumb and index finger. The knob portion 21 has a triangular display indicating the direction in which the seal 20 is peeled off (hereinafter, also referred to as “peeling direction DP”).

As shown in FIG. 2, the outlet 12 has a shape extending in the long axis direction DL along the direction in which the seal 20 is peeled off. In a plan view, the outlet 12 has an oval shape with a long axis along the peeling direction DP. Before peeling off the seal 20, the outlet 12 is not open. That is, before the seal 20 is peeled off, the rim portion 13 and the disconnection portion 14 are connected (see FIG. 3). When the seal 20 is peeled off along the peeling direction DP, the disconnection portion 14 is separated along the cut 15 to open the outlet 12. When the outlet 12 opens, a part of the wet tissue 2 contained in the packaging bag 10 is exposed.

<Mouth edge>
As shown in FIG. 3, the rim portion 13 has a point-symmetrical shape with the center C of the major axis direction DL (peeling direction DP) as the center of rotation. The rim portion 13 includes a pair of extending portions 30, a thin-walled portion 31, and a pair of continuous portions 32. The rim portion 13 is formed with a cut 15 that is half-cut along the outer shape of the cut-off portion 14 (see FIG. 4). For example, the depth of the cut 15 is 40% to 70% of the thickness of the take-out surface main body 11. For example, when the take-out surface main body 11 has a PET film on the first layer 11a and a vapor-deposited film such as aluminum on the second layer 11b, it is preferable that at least the first layer 11a is cut. In the present embodiment, the cut 15 is formed on the side of the take-out surface main body 11 on the side of the seal 20, and is not formed on the side of the take-out surface main body 11 opposite to the seal 20. For example, the length of the DL in the major axis direction of the rim portion 13 is 40 mm to 60 mm.

<Extension part>
The extending portion 30 has a cut extending along the peeling direction DP. For example, the depth of the cut 15 of the extending 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 extending portion 30 is formed in the layer 11a of the plurality of layers 11a and 11b excluding the last layer 11b. The "last layer" means the last layer counting from the side where the cut 15 is formed in the take-out surface main body 11 (for example, the side where the blade is inserted). In the present embodiment, the cut 15 of the extending portion 30 is formed in the first layer 11a of the two layers 11a and 11b excluding the last second layer 11b counting from the seal 20 side. That is, the cut 15 of the extending portion 30 is formed only in the first layer 11a of the plurality of layers 11a and 11b. The "first layer" means the first layer counting from the side that forms the cut 15 in the take-out surface main body 11 (for example, the side where the blade is inserted).

As shown in FIG. 3, the extending portion 30 has a convex arc shape outward in a direction orthogonal to the long axis direction DL (hereinafter, also referred to as “minor axis direction DS”) in a plan view. The extending portion 30 is located at the center position of the peeling direction DP and is located on the outermost side of the short axis direction DS. Hereinafter, in the peeling direction DP, the side at the beginning of peeling of the seal 20 is the "upstream side of the peeling direction DP", and in the peeling direction DP, the side opposite to the upstream side of the peeling direction DP, that is, the side at the end of peeling the seal 20 is "downstream of the peeling direction DP". "Side". The pair of extending portions 30 are continuous with each other at the end on the downstream side of the DP in the peeling direction.

The extending portion 30 has a radius of curvature R1 larger than the radius of curvature R2 of the thin portion 31 at the central position of the peeling direction DP. The distance between the center C of the major axis DL of the mouth edge portion 13 and the outer end of the minor axis DS of the extending portion 30 (the outermost portion in the minor axis DS) is the curvature of the thin portion 31. It is larger than the radius R2. 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 wall>
As shown in FIG. 4, the thin-walled portion 31 has a cut 15 deeper than the extending 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 plurality of 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 reach the last layer 11b, and is also formed in the last layer 11b. The cut 15 of the thin portion 31 does not penetrate the last layer 11b. In FIG. 4, the cut 15 is exaggerated so that the difference in depth between the thin portion 31 and the extending portion 30 can be easily understood.

As shown in FIG. 3, the thin-walled portion 31 is provided on the upstream side of the DP in the peeling direction with respect to the pair of extending portions 30. The thin-walled portion 31 is continuous with the end of the pair of extending portions 30 on the upstream side of the DP in the peeling direction via the continuous portion 32. The thin portion 31 has a convex arc shape on the side opposite to the peeling direction DP in a plan view. In a plan view, the thin-walled portion 31 has a curved shape that is convex outward so as to be located outside the DS in the minor axis direction toward the downstream side of the DP in the peeling direction, starting from the outer end on the side opposite to the DP in the peeling direction. Is doing. For example, the radius of curvature R2 of the thin portion 31 is 2 mm to 4 mm.

<Continuous part>
The continuous portion 32 is arranged between the extending portion 30 and the thin-walled portion 31 in the major axis direction DL. The pair of continuous portions 32 are the end on the thin-walled portion 31 side of the pair of extending portions 30 in the peeling direction DP (the end on the upstream side of the peeling direction DP) and both ends of the thin-walled portion 31 (the end on the downstream side of the peeling direction DP). And each are continuous.

As shown in FIG. 4, in the continuous portion 32, the depth of the cut 15 gradually becomes shallower from the side of the thin-walled portion 31 toward the side of the extending portion 30. The depth of the cut 15 of the continuous portion 32 is between the depth of the cut 15 at the end of the thin portion 31 on the downstream side of the peeling direction DP and the depth of the cut 15 at the end of the extending portion 30 on the upstream side of the peeling direction DP. It's changing. For example, the depth of the cut of the continuous portion 32 varies in the range of 50% to 60% of the thickness of the take-out surface main body 11.

<Method of forming the rim>
As shown in FIG. 5, as a method of forming the rim portion 13, a transport device 50 for transporting a long strip-shaped base material 40 is used. The transport device 50 includes a pair of transport rolls 51, 52 (first roll 51 and second roll 52) that face each other. The base material 40 has a plurality of take-out surface main body forming portions 41 (parts for forming the take-out surface main body 11) arranged in the transport direction DT. The mouth edge portion 13 of the take-out surface main body 11 is formed while transporting the long strip-shaped base material 40 using a pair of transport rolls 51 and 52.

On the surface of the first roll 51, a mold 55 having a blade 56 having an outer shape along the rim portion 13 is attached. For example, the height of the blade 56 is 0.1 mm to 0.9 mm. The portion of the blade 56 corresponding to the thin portion 31 of the rim portion 13 is higher than the other portions.

For example, when the pair of transport rolls 51 and 52 are rotated, the base metal 40 is transported in one direction (moves in the transport direction DT). In the process of transporting the base material 40, the blade 56 of the mold 55 bites into the take-out surface main body forming portion 41, and the rim portion 13 is formed. Since the blade 56 of the mold 55 is raised as described above, the blade 56 bites into the portion corresponding to the thin portion 31 of the rim portion 13 larger than the other portions. In the example of FIG. 5, the major axis direction DL of the rim portion 13 is parallel to the transport direction DT of the base material 40.

<Effect>
As described above, the package 1 according to the above embodiment is a package 1 capable of accommodating the wet tissue 2, and is located at the outer edge of the outlet 12 capable of taking out the wet tissue 2 housed in the package 1. A film-shaped take-out surface main body 11 having a rim portion 13 along the rim portion 13 and a cut-out portion 14 having an outer shape along the rim portion 13, and a seal 20 attached to the take-out surface main body 11 and covering the cut-off portion 14 are provided. The mouth edge portion 13 is provided with a pair of extending portions 30 having a cut 15 extending along the peeling direction DP and an end of the pair of extending portions 30 provided on the upstream side of the peeling direction DP from the pair of extending portions 30. Includes a thin-walled portion 31 that is continuous with, has a convex arc shape on the side opposite to the peeling direction DP, and has a cut 15 deeper than the extending portion 30.

According to this configuration, since the thin portion 31 of the rim portion 13 has a deeper cut 15 than the extending portion 30, the force for separating the disconnection portion 14 from the thin portion 31 of the rim portion 13 as a starting point is reduced. Can be done. Once the separation portion 14 is separated by the thin-walled portion 31, it is separated along the pair of extending portions 30 so as to follow the separation of the thin-walled portion 31. Therefore, it becomes easier to separate the cut-off portion 14 as compared with the case where the cut portion 15 is formed at a uniform depth along the outer shape of the cut-off portion 14. That is, it is possible to prevent the outlet 12 from being formed when the seal 20 is peeled off and from not being formed in the intended shape. In addition, since the cut 15 of the extending portion 30 is easily made shallow, even if the cut 15 of the thin-walled portion 31 is deepened, the cut-off portion 14 is displaced or comes off during manufacturing (before the seal 20 is attached to the take-out surface main body 11). It is possible to suppress such things. Therefore, the outlet 12 can be stably formed in the intended shape.
In addition, the airtightness of the package 1 can be maintained. Therefore, it is possible to suppress the invasion of foreign substances and the drying of the wet tissue 2.

According to the above embodiment, the rim portion 13 is continuous with the end of the pair of extending portions 30 on the thin-walled portion 31 side and both ends of the thin-walled portion 31 in the peeling direction DP, and extends from the thin-walled portion 31 side. The following effects are obtained by further providing a pair of continuous portions 32 in which the depth of the cut 15 gradually becomes shallower toward the side of 30.
Since there is a continuous portion 32 between the thin-walled portion 31 and the extending portion 30, the difference in depth between the thin-walled portion 31 and the extending portion 30 is gradually reduced. Therefore, the separation portion 14 is smoothly separated along the pair of continuous portions 32 and the pair of extending portions 30 starting from the thin portion 31 of the mouth edge portion 13. Therefore, it becomes easier to separate the disconnection portion 14.

According to the above embodiment, the cut 15 is formed on the side of the seal 20 of the take-out surface main body 11 and is not formed on the side opposite to the seal 20 of the take-out surface main body 11, so that the following effects are obtained.
The airtightness of the package 1 can be more effectively maintained as compared with the case where the cut 15 is formed on the side opposite to the seal 20 of the take-out surface main body 11.

According to the above embodiment, the take-out surface main body 11 is a laminate of a plurality of layers 11a and 11b, and thus has the following effects.
The take-out surface main body 11 can have a plurality of functions, such as stacking a layer that does not allow moisture to pass through and a layer that develops a good color in printing.

According to the above embodiment, the cut 15 of the extending portion 30 is formed in the layer 11a other than the last layer 11b of the plurality of layers 11a and 11b, and the cut 15 of the thin wall portion 31 is among the plurality of layers 11a and 11b. By penetrating the first layer 11a, the following effects are obtained.
Since the cut 15 of the extending portion 30 is not formed in the last layer 11b, the separation portion 14 can be easily separated from the extraction surface main body 11 while maintaining the airtightness of the package 1.

According to the above embodiment, the cut 15 of the thin-walled portion 31 penetrates the first layer 11a of the plurality of layers 11a and 11b to reach the last layer 11b, and is also formed in the last layer 11b. , Has the following effects.
Since a cut is formed up to the last layer 11b of the laminate in the thin-walled portion 31, the separation portion 14 can be separated from the extraction surface main body 11 while suppressing delamination.

<Modified example of the first embodiment>
In the above embodiment, the example in which the sheet body is the wet tissue 2 has been described, but the present invention is not limited to this. For example, the sheet body may be a sheet body other than the wet tissue 2 such as a wet sheet or a dry sheet.

In the above embodiment, the cut 15 is formed on the side of the seal 20 of the take-out surface main body 11 and is not formed on the side opposite to the seal 20 of the take-out surface main body 11, but the present invention is not limited to this. For example, as shown in FIG. 6, the cut 15 is formed on the side opposite to the seal 20 of the take-out surface main body 11, and may not be formed on the side of the seal 20 of the take-out surface main body 11. According to this configuration, the cut-off portion 14 is separated from the take-out surface main body 11 when the seal 20 is peeled off, as compared with the case where the cut 15 is formed on the side of the seal 20 of the take-out surface main body 11 (see FIG. 4). easy.

In the above embodiment, an example in which the take-out surface main body 11 is a laminate of two layers 11a and 11b has been described, but the present invention is not limited to this. For example, the take-out surface main body 11 may be a single layer or a laminate having three or more layers.

In the above embodiment, the example in which the cut 15 of the extending portion 30 is formed in the layer 11a excluding the last layer 11b of the plurality of layers 11a and 11b has been described, but the present invention is not limited to this. For example, the cut 15 of the extending portion 30 may be formed up to the last layer 11b of the plurality of layers 11a and 11b. According to this configuration, since the cut 15 of the extending portion 30 is formed in all the layers of the plurality of layers 11a and 11b, the separating portion 14 can be easily separated from the extraction surface main body 11 while suppressing delamination. Can be done.

In the above embodiment, the example in which the cut 15 of the thin-walled portion 31 is formed in each of the plurality of layers 11a and 11b has been described, but the present invention is not limited to this. For example, as shown in FIG. 7, the cut 15 of the thin-walled portion 31 may be formed only in the first layer 11a of the plurality of layers 11a and 11b. That is, the cut 15 of the extending portion 30 and the cut 15 of the thin-walled portion 31 may be formed only in the first layer 11a of the plurality of layers 11a and 11b. According to this configuration, since the last layer 11b (the layer closest to the wet tissue 2) has no cut 15 so that the liquid does not permeate between the layers of the laminate, delamination is unlikely to occur. That is, since the cut 15 is on the side of the seal 20 of the take-out surface main body 11, the problem of liquid permeation from the wet tissue 2 into the cut 15 does not occur.

In the example of FIG. 7, when the cut 15 is on the side of the seal 20 of the take-out surface main body 11, the cut 15 of the extending portion 30 and the cut 15 of the thin-walled portion 31 are formed only on the first layer 11a of the plurality of layers 11a and 11b. Although the explanation has been given with an example of being formed, the present invention is not limited to this. For example, as shown in FIG. 8, when the cut 15 is on the side opposite to the seal 20 of the take-out surface main body 11, the cut 15 of the extending portion 30 and the cut 15 of the thin-walled portion 31 are the first of the plurality of layers 11a and 11b. It may be formed only on one layer 11b of the above. In the example of FIG. 8, the arrangement of the first layer and the last layer (for example, the direction in which the blade is inserted) is opposite to that of the example of FIG. According to this configuration, since the liquid does not permeate between the layers of the laminate because the cut 15 is provided only in the first layer 11b (the layer closest to the wet tissue 2), delamination is unlikely to occur.

In the above embodiment, an example in which the outlet 12 has a shape extending in the long axis direction DL along the direction in which the seal 20 is peeled off has been described, but the present invention is not limited to this. For example, the outlet 12 may have a shape extending in a direction intersecting the direction in which the seal 20 is peeled off. In a plan view, the outlet 12 may have an oval shape with a minor axis along the peeling direction DP. Alternatively, in a plan view, the outlet 12 may have a perfect circular shape.

In the above embodiment, an example of the packaging body 1 accommodating the wet tissue 2 (sheet body) has been described, but the present invention is not limited to this. For example, the present invention may be applied to a container other than the packaging body 1 of the sheet body (for example, a container for juice in a paper carton).

<Second embodiment>
Hereinafter, the second embodiment of the present invention will be described with reference to the drawings. In the second embodiment, the same components as those in the first embodiment are designated by the same reference numerals. In each figure, the same reference numerals are given to the same configurations. In the second embodiment, a wet tissue (liquid-containing sheet) will be described as an example of the sheet body contained in the package body. For example, a wet tissue has a rectangular shape in a plan view. Wet wipes are made by impregnating non-woven fabric, tissue paper, or the like with a liquid (for example, water mixed with alcohol, a disinfectant, a preservative, a fragrance, or the like).

<Packaging>
As shown in FIG. 9, the package 2001 includes a packaging bag 10 and a seal 20.
The packaging bag 10 has a bag shape having a size capable of accommodating a laminated body in which a plurality of wet tissues 2 are laminated. The packaging bag 10 is made of a flexible film material having airtightness and water resistance.

For example, the packaging bag 10 is formed of a laminated film in which a polyethylene terephthalate (PET) film, an aluminum foil, a so-called heat-sealing film called a sealant, and the like are laminated and bonded in order from the surface (outside). For example, the laminated film may be a PET film on which aluminum, silica, alumina, or the like is vapor-deposited, and a heat-sealing film is laminated on the inner surface.

The packaging bag 10 includes a film-shaped take-out surface main body 2011. The take-out surface main body 2011 is a planar portion on the side where the wet tissue 2 housed in the packaging bag 10 is taken out. For example, the thickness of the take-out surface main body 2011 is several tens of μm. In a plan view, the take-out surface main body 2011 has a rectangular shape larger than the outer shape of the wet tissue 2.

As shown in FIG. 12, the take-out surface main body 2011 is a laminate of a plurality of layers 11a and 11b. For example, the take-out surface main body 2011 has a first layer 11a on the side of the seal 20 in the thickness direction of the take-out surface main body 2011, and a second layer 11b on the opposite side of the seal 20 in the thickness direction of the take-out surface main body 2011. .. For example, the take-out surface main body 2011 has a PET film on the first layer 11a and a thin-film film such as aluminum on the second layer 11b.

As shown in FIG. 10, the take-out surface main body 2011 is formed on the rim portion 2013 (see FIG. 11) along the outer edge of the take-out outlet 2012 from which the wet tissue 2 housed in the packaging bag 10 can be taken out, and the rim portion 2013. It has an outer shape separating portion 14 (see FIG. 11) along the outer shape. The rim portion 2013 is formed with a cut 15 (see FIG. 12) that is half-cut along the outer shape of the cut-off portion 14. Note that in FIG. 12, the detached portion 14 is not shown.

As shown in FIG. 9, the sticker 20 is attached to the take-out surface main body 2011. The seal 20 covers the separating portion 14 (see FIG. 11). In plan view, the seal 20 has a larger outer shape than the detached portion 14. The seal 20 has an adhesive layer (not shown) on the side of the separating portion 14. The seal 20 is attached to the take-out surface main body 2011 so as to be repeatedly peelable.

The seal 20 has a knob portion 21 that is picked when the seal 20 is peeled off. For example, the picking portion 21 has a size that allows the user to pick with the thumb and index finger. The knob portion 21 has a triangular display indicating the direction in which the seal 20 is peeled off (hereinafter, also referred to as “peeling direction DP”).

As shown in FIG. 10, the outlet 2012 has a shape extending in the long axis direction DL along the direction in which the seal 20 is peeled off. Before peeling off the seal 20, the outlet 2012 is not open. That is, before the seal 20 is peeled off, the rim portion 2013 and the disconnection portion 14 are connected (see FIG. 11). When the seal 20 is peeled off along the peeling direction DP, the disconnection portion 14 is separated along the cut 15 to open the outlet 2012. When the outlet 2012 opens, a part of the wet tissue 2 contained in the packaging bag 10 is exposed.

<Mouth edge>

The rim portion 2013 includes a first curved portion 2030, a pair of extending portions 2031, a stopping portion 2032, a pair of second curved portions 2033, and a pair of continuous portions 2034. The portion of the rim portion 2013 excluding the stop portion 2032 (first curved portion 2030, pair of extending portions 2031, pair of second curved portion 2033 and pair of continuous portions 2034) is along the outer shape of the separating portion 14. A half-cut cut 15 is formed (see FIG. 12). For example, the length of the DL in the major axis direction of the rim portion 2013 is 40 mm to 60 mm.

The cut 15 is formed at a uniform depth along the outer shape of the cut-off portion 14 (see FIG. 12). For example, the depth of the cut 15 is 40% to 70% of the thickness of the take-out surface main body 2011. For example, when the take-out surface main body 2011 has a PET film on the first layer 11a and a vapor-deposited film such as aluminum on the second layer 11b, it is preferable that at least the first layer 11a is cut. In the present embodiment, the cut 15 is formed in the first layer 11a on the side of the seal 20 of the take-out surface main body 2011, and is not formed in the second layer 11b on the side opposite to the seal 20 of the take-out surface main body 2011. The cut 15 is formed in the layers other than the last layer 11b of the plurality of layers 11a and 11b. In the present embodiment, the cut 15 is formed in the first layer 11a of the two layers 11a and 11b excluding the last second layer 11b counting from the seal 20 side.

The first curved portion 2030 has a convex arc shape on each of the peeling start side and the peeling end side of the seal 20. Hereinafter, in the peeling direction DP, the side at the beginning of peeling of the seal 20 is the "upstream side of the peeling direction DP", and in the peeling direction DP, the side opposite to the upstream side of the peeling direction DP, that is, the side at the end of peeling the seal 20 is "downstream of the peeling direction DP". "Side". In a plan view, the first curved portion 2030 starts from the end on the side where the seal 20 starts to be peeled off, and goes in the direction orthogonal to the long axis direction DL as it goes toward the downstream side of the peeling direction DP (hereinafter also referred to as "short axis direction DS"). It has an outwardly convex curved shape so as to be located outside. The first curved portion 2030 is provided on both sides of the long axis direction DL of the rim portion 2013. For example, the radius of curvature R1 of the first curved portion 2030 is 2 mm to 4 mm.

<Extension part>
The extending portion 2031 is continuous with both ends of the first curved portion 2030. The extending portion 2031 extends along the peeling direction DP. The extending portion 2031 extends linearly from the end of the first curved portion 2030 on the downstream side of the DP in the peeling direction toward the downstream side of the DP in the peeling direction in a plan view. The pair of extending portions 2031 are provided substantially parallel to each other in the major axis direction DL.

"Approximately parallel" means that the pair of extending portions 2031 are substantially parallel to each other within the allowable range of the design error (dimensional error) of the packaging bag 10. The “substantially parallel” includes the case where the pair of extending portions 2031 are tilted obliquely within a range of ± 5 ° with respect to the major axis of the outlet 2012. The term "substantially parallel" includes the case where the pair of extending portions 2031 are completely parallel to each other. Further, "substantially parallel" includes a case where the pair of extending portions 2031 are tilted obliquely with respect to the peeling direction DP within a range in which the take-out surface main body 2011 can be suppressed from being torn when the seal 20 is peeled off. ..

A pair of extending portions 2031 are provided on both sides of the long axis direction DL of the rim portion 2013. The extending portion 2031 has a length shorter than the radius of curvature R1 of the first curved portion 2030. For example, the length of the extending portion 2031 is 1 mm to 2 mm. For example, the length of the extending portion 2031 is preferably about half the length of the radius of curvature R1 of the first curved portion 2030.

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

<Second curve part>
The second curved portion 2033 is provided on the side opposite 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 DP in the peeling direction with respect to the first extending portion 30. The second curved portion 2033 is provided at the center of the long axis direction DL of the rim portion 2013. The second curved portion 2033 has an arc shape that is convex outward in the short axis direction DS in a plan view. The second curved portion 2033 is located at the center position of the peeling direction DP and is located on the outermost side of the short axis direction DS.

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

<Continuous part>
The continuous portion 2034 is arranged between the extending portion 2031 and the second curved portion 2033 in the major axis direction DL. The continuous portion 2034 has an arc shape that is convex inward in the short axis direction DS in a plan view. The pair of continuous portions 2034 are the end of the pair of extending portions 2031 opposite to the first curved portion 2030 in the major axis direction DL (the end on the downstream side of the DP in the peeling direction) and the pair of second curved portions 2033. It is continuous with the end on the side of one curved portion 2030 (the end on the upstream side of DP in the peeling direction). The pair of continuous portions 2034 are provided on both sides of the long axis direction DL of the rim portion 2013. For example, the radius of curvature Rc of the continuous portion 2034 is 1 mm to 2 mm. For example, the radius of curvature Rc of the continuous portion 2034 is preferably about the same as the length of the extending portion 2031.

<Method of forming the rim>
As shown in FIG. 13, as a method of forming the rim portion 2013, a transport device 50 for transporting a long strip-shaped base material 40 is used. The transport device 50 includes a pair of transport rolls 51, 52 (first roll 51 and second roll 52) that face each other. The base material 40 has a plurality of take-out surface main body forming portions 41 (parts for forming the take-out surface main body 2011) arranged in the transport direction DT. The rim portion 2013 of the take-out surface main body 2011 is formed while transporting the long strip-shaped base material 40 using a pair of transport rolls 51 and 52.

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

For example, when the pair of transport rolls 51 and 52 are rotated, the base metal 40 is transported in one direction (moves in the transport direction DT). In the process of transporting the base material 40, the blade 56 of the mold 55 bites into the take-out surface main body forming portion 41, and the rim portion 2013 is formed. In the example of the figure, the major axis direction DL of the rim portion 2013 is parallel to the transport direction DT of the base material 40.

<Effect>
As described above, the package 2001 according to the second embodiment is a package 2001 capable of accommodating the wet tissue 2, and has an outlet 2012 capable of taking out the wet tissue 2 housed in the package 2001. A film-shaped take-out surface main body 2011 having a mouth edge portion 2013 along the outer edge and an outer shape cut-off portion 14 along the mouth edge portion 2013, and a seal 20 attached to the take-out surface main body 2011 and covering the cut-off portion 14. The rim portion 2013 includes a pair of extending portions 2031 having a cut 15 and a pair of extending portions 2031 that are continuous at both ends of a convex curve opposite to the peeling direction DP and extend along the peeling direction DP, and the extending portion 2031. 2032, which is provided in the middle of the above and is thicker than the thickness of the extending portion 2031.

According to this configuration, since a part of the extending portion 2031 is reinforced by the stopping portion 2032, it is easy to deepen the cut 15 of the rim portion 2013. Therefore, it becomes easy to separate the rim portion 2013. That is, it is possible to prevent the outlet 2012 from being formed when the seal 20 is peeled off, and it is possible to prevent the outlet 2012 from being formed in an intended shape. In addition, even if the cut 15 of the rim portion 2013 is deepened, it is possible to prevent the disconnection portion 14 from being displaced or detached during manufacturing (before the seal 20 is attached to the take-out surface main body 2011). Therefore, the outlet 2012 can be stably formed in the intended shape.
In addition, the airtightness of the package 2001 can be maintained. Therefore, it is possible to suppress the invasion of foreign substances and the drying of the wet tissue 2.
In addition, since the separation portion 14 is separated along the pair of extending portions 2031 starting from the curve of the mouth edge portion 2013, the separation portion 14 can be easily separated smoothly.
