Description

Package

The present invention relates to a package of an absorbent article.

A package in which an absorbent article such as a urine absorbing pad is stored in a packaging bag is known. The packaging bag has a perforated line on the outside. The user cuts off the weakening line to form an opening in the packaging bag, and takes out the absorbent article stored in the packaging bag from the opening.

As such a wrapping body, for example, Patent Document 1 discloses a wrapping bag (packaging body) for disposable diapers and the like. This packaging bag (packaging body) is substantially parallel to the bottom surface of the packaging bag (packaging body) in the section from the upper surface of the object to be filled and accommodated below the seal line of the upper opening to the vicinity thereof. A break line (weak line) is attached.

Japanese Unexamined Patent Publication No. 2001-301859

The user uses a package containing an absorbent article in various modes. For example, there may be an embodiment in which the upper surface portion, which is a portion above the weakening line in the packaging bag, is removed to form an opening on the upper side of the packaging bag, and the absorbent article is taken out from the opening. That is, there may be a mode in which the package is completely opened. Further, for example, a part of the outer periphery of the upper surface portion of the packaging bag is torn to form an opening on the upper side of the packaging bag while the upper surface portion is partially connected to the remaining portion of the packaging bag. There may be an embodiment of taking out the absorbent article from. That is, there may be a mode in which the package is partially opened. In this aspect, depending on the situation, the upper surface portion can be gripped and the package can be easily carried, and the absorbent article can be taken out from the opening at any place. In this way, the degree of opening of the upper surface of the package is adjusted according to various modes of use.

In the package of Patent Document 1, a weakening line may be continuously provided over the entire circumference of the packaging bag. In this case, the upper surface of the packaging bag is removed to form an opening, thus completely opening the package, and the opening is opened with the upper surface partially bonded to the rest of the packaging bag. It is easy to form, and thus to partially open the package. That is, in any of the embodiments, the package is easy to open. However, in the embodiment of partially opening the package, the weight of the absorbent article may cause further weakening line separation between the top surface and the rest of the package bag when the package is carried. There is. In that case, the upper surface portion is likely to come off from the remaining portion of the packaging bag, and it becomes difficult to carry the package. That is, it is difficult to control the opening of the package because the package cannot be maintained in a partially opened state and may be in a completely opened state.

On the other hand, in the package of Patent Document 1, weakening lines are independently provided at the corners of the packaging bag at the same height, and the front portion, both side surface portions, and the back surface portion are slightly lower than the weakening lines. Further weakening lines may be provided for each. In this case, these plurality of weakening lines are not continuously provided over the entire circumference of the packaging bag. That is, at the corners, adjacent weakening lines are separated from each other. Therefore, in the embodiment of partially opening the package, some of the multiple weakening lines between the top surface and the rest of the packaging bag, due to the weight of the absorbent article, when the package is carried. Detachment of the weakening line may occur. However, the separation of those weakening lines stops at the corners, so it does not extend to the adjacent weakening lines. That is, the disconnection does not occur in all of the plurality of weakening lines, and the upper surface portion does not come off from the packaging bag. Thereby, the upper surface portion can be gripped and the package can be carried. That is, it is easy to control the opening of the package. However, since the multiple weakening lines are separated from each other, all of the multiple weakening lines are separated to remove the upper surface of the packaging bag, and some of the multiple weakening lines are separated to separate the upper surface. It is not easy to partially separate. That is, in any aspect, it is not easy to open the package.

As described above, in the package of Patent Document 1, it is difficult to achieve both the ease of opening the package and the controllability of the degree of opening of the package.

Further, in the case of a package, if the size of the opening formed in the packaging bag is too large, the absorbent article may unintentionally fall out of the opening. On the other hand, if the size of the opening is too small, when the absorbent article is taken out, it may be caught in the opening and it may be difficult to take out.

Therefore, an object of the present invention is to provide a package that can achieve both the ease of opening the package and the controllability of the degree of opening of the package.

Further, another object of the present invention is to prevent the absorbent article from falling out from the opening and to take out the absorbent article from the opening in the packaging body in which the opening is formed by the weakening line in the packaging bag. It is an object of the present invention to provide a package and a method for manufacturing the same, which can be compatible with facilitating the above.

The present embodiment relates to the following aspects.
[Aspect 1]
A package having a width direction, a depth direction, and a vertical direction, a plurality of absorbent articles, and a packaging bag having a plurality of side surfaces and storing the plurality of absorbent articles. The plurality of side surface portions include a front surface portion, a rear surface portion, a right surface portion, and a left surface portion, and the packaging bag includes a portion where the front surface portion and the right surface portion intersect, and a portion where the front surface portion and the left surface portion intersect. Each of the portion where the rear surface portion and the right surface portion intersects and the portion where the rear surface portion and the left surface portion intersect has a corner portion, and each of the front surface portion and the rear surface portion extends along the width direction. A first weakening line formed so as to extend along the depth direction in each of the right surface portion and the left surface portion, and a second weakening line formed so as to straddle the corner portion. The first weakening lines that are adjacent to each other are separated from each other at the corners, and the first weakening line and the second weakening line that are adjacent to each other are separated from each other, and the second weakening lines that are adjacent to each other are separated from each other. The distance between the line and the first weakening line is shorter than the distance between adjacent first weakening lines, and the extension of the end of the second weakening line is adjacent to the end of the second weakening line. A package that intersects the first weakening line.

In this package, a second weakening line is formed in the vicinity of the first weakening line at the corner portion, and an extension line at the end of the second weakening line intersects the first weakening line adjacent to the second weakening line. There is.
Therefore, in the mode of completely opening the package and the mode of partially opening the package, the user can easily apply the force of the disconnection to the first weakening line after disconnecting the second weakening line. Since it can be transferred to, the first weakening line can be easily separated. Therefore, by separating the required number of the first weakening wire and the second weakening wire, the upper surface portion of the packaging bag can be easily removed from the packaging bag, and the upper surface portion can be easily partially separated.
Further, in the present package, a plurality of first weakening lines provided over the entire circumference (front portion, rear surface portion, right surface portion and left surface portion) of the packaging bag are not continuously provided. That is, at the corners, the adjacent first weakening lines are separated from each other. Further, the plurality of second weakening lines provided at the full-width portion of the packaging bag are separated from each other by a predetermined distance from the adjacent first weakening line among the plurality of first weakening lines. In this case, the upper surface portion in the vertical direction from the first weakening line and the second weakening line of the front surface portion, the rear surface portion, the right surface portion, and the left surface portion is the upper surface portion.
Here, in the embodiment of partially opening the package, when the upper surface of the packaging bag is gripped and carried, the weight of the absorbent article causes the separating force to be the first weakening line separated for opening. From, the separation may occur or proceed by propagating to the first weakening line that is not separated. However, in this package, the separation of the first weakening line stops at the corner and does not shift to the adjacent second weakening line, and does not further shift to the adjacent first weakening line. The upper surface does not come off from the packaging bag. As a result, the user can grasp the upper surface portion and carry the package to another place (the carrying durability becomes high).
As described above, the packaging body adjusts the degree of separation of the upper surface portion of the packaging bag according to various usage modes, that is, the controllability of the opening degree of the packaging body and the upper surface portion of the packaging bag. It is possible to achieve both complete or partial easy separation, that is, ease of opening the package.

[Aspect 2]
The package according to aspect 1, wherein at least an end portion of the second weakening line overlaps with the adjacent first weakening line in the vertical direction.
In this package, at least the end of the second weakening line overlaps with the adjacent first weakening line in the vertical direction. Therefore, when the user tries to open the package and disconnects the second weakening line, the force of the disconnection can be reliably transferred to the first weakening line, and the first weakening line can be separated more easily. Can be done. Therefore, the package can be easily opened.

[Aspect 3]
The first weakening line is formed at the same position as the upper edge of the plurality of absorbent articles in the vertical direction or at a position above the edge, and the second weakening line is the first weakening line. The package according to

aspect

1 or 2, which is formed at a position above the line in the vertical direction.
In this package, the first weakening line is formed in the vertical direction at the same position as the upper edge of the absorbent article stored in the packaging bag or at a position above the edge, and the second weakening line is formed. Is located above the first weakening line in the vertical direction. Therefore, the position of the second weakening line does not overlap with the position of the absorbent article in the package. Therefore, even if the package is inflated with an absorbent article, the user can easily pick the vicinity of the second weakening line, for example, without being affected by the inflated portion, and perform the second weakening. The lines can be easily separated. That is, the package can be easily opened.

[Aspect 4]
The package according to any one of aspects 1 to 3, wherein the extension line at least at the end of the second weakening line intersects the adjacent first weakening line at an acute angle.
In this package, the extension of at least the end of the second weakening line intersects the adjacent first weakening line at an acute angle. Therefore, when the user tries to open the package and disconnects the second weakening line, the force of the disconnection is applied to the second weakening line along the acute angle of the second weakening line with respect to the first weakening line. The line can be smoothly transitioned from the line to the first weakening line. Thereby, both weakening lines can be separated more easily, and the package can be easily opened.

[Aspect 5]
The second weakening line has a convex shape on the upper side or the lower side in the vertical direction, with the central portion of the second weakening line in the direction along the surface of the package as an apex. The package according to any one of the items.
In this package, the second weakening line has a convex shape in the vertical direction, with the central portion in the direction along the surface of the package as the apex, and thus both sides, that is, adjacent first weakening lines. The portion on the line side has a shape that asymptotes to the first weakening line. Therefore, when the user tries to open the package and disconnects the second weakening line, the force of the disconnection is applied to the second weakening line along the portion of the second weakening line on the first weakening line side. It is possible to make a smoother transition from the first weakening line to the first weakening line. Thereby, the separation at both weakening lines can be performed more easily, and the package can be opened more easily.

[Aspect 6]

The present package includes a handle portion provided on a front surface portion, a rear surface portion, a right surface portion, and an upper portion in the vertical direction on the left surface portion, for example, an upper surface portion or an upper portion of the upper surface portion. Thereby, a part of the outer periphery of the upper surface portion of the packaging bag can be separated by the first weakening line, and the partially bonded upper surface portion can be grasped by the handle to easily carry the package to another place. Here, when carrying such a package, the weight of the absorbent article may separate the remaining portion of the outer circumference of the upper surface from the rest of the packaging bag. However, since this package has the above-mentioned structure, it does not cause a situation in which the partially bonded upper surface portions are separated.

[Aspect 7]
The right surface portion and the left surface portion are portions folded in a valley fold on the right side and the left side in the width direction between the front surface portion and the rear surface portion, respectively, and the right surface portion and the front surface portion are the same. The second weakening line at the corner portion has a shape symmetrical with respect to the boundary line between the right surface portion and the front surface portion, and the second weakening line at the corner portion between the right surface portion and the rear surface portion. Has a shape that is line-symmetrical with respect to the boundary line between the right surface portion and the rear surface portion, and the second weakening line at the corner portion between the left surface portion and the front surface portion is the left surface portion and the front surface portion. The second weakening line of the corner portion between the left surface portion and the rear surface portion has a shape symmetrical with respect to the boundary line with the portion, and the second weakening line is with respect to the boundary line between the left surface portion and the rear surface portion. The package according to any one of aspects 1 to 6, which has a line-symmetrical shape.
This package is a gusset type package because the right surface portion and the left surface portion are folded in a valley fold between the front surface portion and the rear surface portion, respectively. The second weakening line has a shape that is line-symmetrical with respect to the boundary line between each of the right surface portion and the left surface portion and each of the front surface portion and the rear surface portion. As a result, the second weakening line is separated from the corners of the right and left surfaces and the front and rear surfaces, respectively, so that the second weakening line and the front surface of the right and left surfaces are separated from each other. And each second weakening line of the rear surface portion can be broken together at the same time. Thereby, both second weakening lines can be separated more easily, and the package can be opened more easily as a whole.

[Aspect 8]
The first weakening line is formed at the same position as the upper edge of the plurality of absorbent articles housed in the package in the vertical direction or at a position above the edge, and the second weakening line is formed. The package according to aspect 7, wherein the weakening line is located above the first weakening line in the vertical direction.
In this package, the first weakening line is formed at the same position as the upper edge of the plurality of absorbent articles or at a position above the edge, and the second weakening line is located above the first weakening line. There is. Therefore, the position of the second weakening line in the package does not overlap with the position of the stored absorbent article. Therefore, even if the package is inflated with the stored absorbent article, the user can easily pick the vicinity of the second weakening line, for example, without being affected by the inflated portion. The second weakening line can be easily separated. That is, the package can be easily opened.

[Aspect 9]
The package according to any one of aspects 1 to 8, wherein the distance between the adjacent first weakening line and the second weakening line is longer than the distance between the weakening portions constituting the first weakening line.
In this package, the distance between the first weakening line and the second weakening line is longer than the distance between the weakening portions constituting the first weakening line. Therefore, in the embodiment of partially opening the package, when the upper surface portion is gripped and the package is carried, the disconnection of the first weakening line propagates to the second weakening line even if the weight of the absorbent article is heavy. Instead, it will stop at the corner. As a result, the upper surface portion can be gripped and the package can be stably carried to another place (the carrying durability is increased).

[Aspect 10]
The package according to any one of aspects 1 to 9, wherein the second weakening line has an arch-shaped shape having an apex at the center in the direction along the surface of the package.
In the present package, the second weakening line has an arch shape having the center in the direction along the surface of the package as an apex, and thus has a substantially arc shape. Therefore, in the embodiment of partially opening the package, when the upper surface portion is grasped and the package is to be carried, the weight of the absorbent article causes the separation of the first weakening line to propagate to the adjacent second weakening line. Even so, since the second weakening line is arched, the separating force is dispersed, and it becomes difficult for the second weakening line to be separated. As a result, the upper surface portion can be gripped and the package can be stably carried to another place (the carrying durability is increased).

[Aspect 11]

A first weakening line formed so as to extend along the depth direction in each of the right surface portion and the left surface portion, and a second weakening line formed so as to straddle the corner portion. The second weakening line is provided with at least one adjacent first weakening line separated from the first weakening line, and at least one of the front surface portion, the rear surface portion, the right surface portion, and the left surface portion. Even if the separation of the first weakening line propagates to the corner portion due to the weight of the plurality of absorbent articles when the upper portion in the vertical direction is grasped and the package is lifted. The packaging is formed in an unreachable position.

The present package has a first weakening line formed so as to extend along the width direction or the depth direction on each of the front portion, the rear surface portion, the right surface portion, and the left surface portion, and is formed so as to straddle the corner portions. It has a second weakening line. Therefore, the package can be easily opened by using the first weakening wire and the second weakening wire. In this case, the upper surface portion in the vertical direction from the first weakening line and the second weakening line of the front surface portion, the rear surface portion, the right surface portion, and the left surface portion is the upper surface portion.
Further, in the embodiment of partially opening the package, after the separation of at least one first weakening line is performed, when the upper surface portion is grasped and the package is lifted, the weight of the absorbent article is applied. , It is possible that the disconnection of the first weakening line propagates toward the corner. Therefore, in this package, the second weakening line at the corner is formed at a position where the separation of the first weakening line cannot be reached even if it propagates to the corner. As a result, it is possible to suppress the occurrence of disconnection of the second weakening line, and it is possible to suppress the occurrence of separation of the first weakening line ahead of the second weakening line. As a result, the upper surface portion can be gripped and the package can be stably carried to another place.
As described above, this package can achieve both the ease of opening the package and the controllability of the degree of opening of the package.

A package in which the position of the lower end in the vertical direction on the line is higher than the position of the lower end in the vertical direction in the plurality of absorbent articles and lower than the position in the middle of the vertical direction in the plurality of absorbent articles.

In this package, the user separates the horizontal weakening line and the two vertical weakening lines at the opening portion of the packaging bag to form an opening in the packaging bag, and the user is stored in the packaging bag through the opening. The absorbent article can be taken out. At that time, the position of the lower end in the vertical direction on the two vertical weakening lines is higher than the position of the lower end in the vertical direction in the plurality of absorbent articles. Therefore, when the opened portion is opened, the lower portion of the absorbent article is located below the lower end of the opening portion, and is protected by the packaging bag. Therefore, it is possible to prevent the absorbent article from unintentionally falling out of the opening. Further, when the absorbent article is taken out, it is possible to prevent other absorbent articles from unintentionally falling out of the opening. Further, the position of the lower end in the vertical direction on the two vertical weakening lines is lower than the position in the middle in the vertical direction in the plurality of absorbent articles. Therefore, when the opened portion is opened, the upper half or more of the absorbent article is located above the lower end of the opening and is exposed from the opening. Therefore, when the absorbent article is taken out, it can be prevented from being caught in the opening. As described above, in this package, it is possible to suppress the falling of the absorbent article from the opening and to facilitate the removal of the absorbent article from the opening.

Hereinafter, a specific description will be given with reference to FIG.

FIG. 8 is a schematic diagram showing the action and effect of the package according to the embodiment. This figure shows, as an example, a state of separation at the first weakening line 21 at the right surface portion 13 and the corner portion 19 between the right surface portion 13 and the rear surface portion 12. However, for the sake of clarity, a plurality of lines parallel to the depth direction D and spaced apart in the vertical direction T are drawn on the surface of the right surface portion 13. The state of the right surface portion 13 is three-dimensionally expressed by changes such as distortion of the plurality of lines.

As shown in FIG. 8, for example, the present package 1 is provided with a first weakening line 21 formed so as to extend along the depth direction D on the right surface portion 13, and is formed so as to straddle the corner portion 19. The second weakening line 22 is provided. Here, in the embodiment in which the package 1 is partially opened, at least the first weakening line 21 of the front surface portion 11 and the right surface portion 13 is separated, and after the first cutting line 21a is formed, the upper surface portion 15 is formed. Is gripped and the package 1 is lifted. At that time, the weight of the absorbent article 3 may cause the first cutting line 21a to propagate toward the corner portion 19.
In that case, if the first cutting line 21a propagates in the direction of the first weakening line 21 as it is, it becomes like the first cutting line 21a0 shown in FIG. Alternatively, the first cutting line 21a is obliquely upward from the direction of the first weakening line 21 due to the relationship between the force that lifts the upper surface portion 15 upward and the force that pushes the right surface portion 13 downward due to the weight of the absorbent article 3. It propagates to the first cutting line 21aX shown in FIG. In any case, if the corner portion 19 does not have the second weakening line 22, the propagation of the first cutting line 21a can be stopped substantially in the middle of the corner portion 19. However, in that case, since the weakening line is not provided at the corner portion 19, it is difficult to remove the upper surface portion 15 when it is desired to remove the weakening line.
Here, in order to facilitate the removal of the upper surface portion 15, as shown in FIG. 8, in the vicinity of the first weakening line 21 at the corner portion 19, the first weakening line 21 and the first weakening line 21 are spaced apart from each other in the vertical direction T. It is conceivable to form a second weakening line 121 extending in parallel in the depth direction D (Patent Document 1). However, even in that case, since the first cutting line 21aX propagates to the second weakening line 121, the second weakening line 121 is separated, and the separation further propagates to the first weakening line 21 of the rear surface portion 12. There is a risk of doing so. In that case, in the end, all the weakening lines may be separated and the upper surface portion 15 may be removed.
Therefore, in the present package 1, as shown in FIG. 8, the second weakening line 22 of the corner portion 19 is formed at a position that cannot be reached even if the disconnection of the first weakening line 21 propagates to the corner portion 19. There is. As a result, it is possible to suppress the occurrence of disconnection of the second weakening line 22, and it is possible to suppress the occurrence of disconnection of the first weakening line 21 ahead of the second weakening line 22. As a result, the upper surface portion 15 can be gripped and the package 1 can be stably carried to another place. As described above, the package 1 can achieve both the ease of opening the package 1 and the controllability of the degree of opening of the package 1.

FIG. 9 is a schematic diagram showing a configuration example of the first weakening line and the second weakening line according to the embodiment. Specifically, it is a schematic diagram which shows the positional relationship between the 1st weakening line 21 and the 2nd weakening line 22 in a corner portion 19 and its vicinity along the surface of a package 1 (packaging bag 2). In the present embodiment, at least the end of the second weakening line 22 may overlap with the adjacent first weakening line 21 in the vertical direction T. That is, the adjacent second weakening line 22 and the first weakening line 21 may overlap by the length dL (> 0) in the vertical direction T. As a result, when the user tries to open the package 1 and disconnects the second weakening wire 22, even if the disconnection direction deviates from the extension line L0 at the end of the second weakening wire 22. , The disconnection can be reliably propagated to the first weakening line 21. That is, the disconnection force of the second weakening line 22 can be reliably transferred to the first weakening line 21, and the first weakening line 21 can be separated more easily. Therefore, the package can be easily opened.
The dL is preferably 0.1 cm or more, and more preferably 0.5 cm or more, from the viewpoint of reliably propagating the disconnection of the second weakening line 22 to the first weakening line 21. The dL is preferably 4 cm or less, and more preferably 3 cm or less, from the viewpoint of sufficiently separating the adjacent first weakening lines 21 from each other.

Further, in the present embodiment, as shown in FIG. 9, the extension line L0 at least at the end of the second weakening line 22 may intersect the adjacent first weakening line 21 at an acute angle. That is, if the angle formed by the extension line L0 and the first weakening line 21 is α, (0 <) α <90 ° may be used. As a result, when the user tries to open the package 1 and separates the second weakening line 22, the force of the disconnection is applied to the sharp inclination (angle) of the second weakening line 22 with respect to the first weakening line 21. Along α), the second weakening line 22 can be smoothly transitioned to the first weakening line 21. Therefore, both weakening lines can be separated more easily, and the package 1 can be easily opened.
Here, α is preferably 15 ° or more, and more preferably 30 ° or more, from the viewpoint of reliably propagating the disconnection of the second weakening line 22 to the first weakening line 21. Further, α is preferably 80 ° or less, more preferably 70 ° or less, from the viewpoint of smoothly propagating the disconnection of the second weakening line 22 to the first weakening line 21.

Further, in the present embodiment, as shown in FIG. 9, the first weakening line 21 is a plurality of weakening portions 21w arranged intermittently and a plurality of non-weakening portions 21v located between the adjacent weakening portions 21w. It may be composed of. In that case, in the present embodiment, the distance d1 between the adjacent first weakening line 21 and the second weakening line 22 may be longer than the distance between the weakening portions 21w constituting the first weakening line 21. That is, if the distance between the weakened portions 21w is d21, d21 <d1 may be used. As a result, in the embodiment in which the package 1 is partially opened, when the upper surface portion 15 is gripped and the package 1 is carried, even if the absorbent article 3 is heavy, the first weakening line 21 is separated. 2 It is difficult to propagate to the weakening line 22, and it is easy to stop at the corner portion 19. As a result, the upper surface portion 15 can be gripped and the package 1 can be stably carried (the carrying durability is increased).

FIG. 10 is a schematic diagram showing a configuration example of the first weakening line and the second weakening line according to the embodiment. Specifically, it is a schematic diagram which shows the positional relationship between the 1st weakening line 21 and the 2nd weakening line 22 in a corner portion 19 and its vicinity along the surface of a package 1 (packaging bag 2). (A) to (d) show variations in the configuration when the second weakening line 22 is located above the first weakening line 21 in the vertical direction T, and (e) to (f) are the second. It shows a variation of the configuration when the weakening line 22 is located below the first weakening line 21 in the vertical direction T.

In the present embodiment, as shown in FIG. 10, the second weakening line 22 is in the vertical direction with the central portion 22p in the direction along the surface of the package 1 (packaging bag 2) in the second weakening line 22 as the apex. It may have a convex shape ((a) to (d)) on the upper side of the T or a convex shape ((e) to (h)) on the lower side. In this case, in the second weakening line 22, the portion on the side of the adjacent first weakening line 21 has a shape that asymptotes to the first weakening line 21. Therefore, when the user tries to open the package 1 and separates the second weakening line 22, the force of the disconnection is applied along the portion of the second weakening line 22 on the first weakening line 21 side. The transition from the second weakening line 22 to the first weakening line 21 can be made more smoothly. Thereby, the separation at both weakening lines can be performed more easily, and the package can be opened more easily.

However, the second weakening line 22 of (a) and (e) is arch-shaped, and the second weakening line 22 of (b) and (f) is a (rounded) triangular shape, and (c), The second weakening line 22 of (g) has a (rounded) triangular shape, but the second weakening line 22 and the first weakening line 21 do not overlap in the vertical direction T. The second weakening line 22 of (d) and (h) is rectangular. However, even in the case of the arch type or the rectangular type, the second weakening line 22 and the first weakening line 21 do not have to overlap in the vertical direction T. Further, the shape of the second weakening line 22 is not limited to this example, and may be another shape, a semicircular shape, a semi-elliptical shape, a trapezoidal shape, or the like. Further, each second weakening line 22 may be line-symmetrical with respect to the boundary line CL. In that case, when the vicinity of the boundary line CL is pinched with a finger to separate the second weakening line 22, the second weakening lines 22 on both side surfaces sandwiching the boundary line CL can be broken together at the same time. ..

Further, it is preferable that the second weakening line 22 has an arch shape and thus has a substantially arc shape ((a), (e)). As a result, in the embodiment in which the package 1 is partially opened, when the upper surface portion 15 is gripped and the package 1 is to be carried, the weight of the absorbent article 3 causes the first weakening lines 21 to be separated from each other adjacent to each other. Even if it propagates to the 2 weakening line 22, the disconnecting force is dispersed in the tangential direction at each portion of the 2nd weakening line 22, and the disconnection of the 2nd weakening line 22 becomes difficult to proceed. As a result, the upper surface portion 15 can be gripped and the package 1 can be stably carried (the carrying durability is increased).

Further, in the present embodiment, as shown in FIGS. 1 to 4, the first weakening line 21 is at the same position as the upper edge 3TE1 of the plurality of absorbent articles 3 in the vertical direction T or above the edge 3TE1. It may be formed at the position of. In that case, the second weakening line 22 is formed at a position above the first weakening line 21 in the vertical direction T. Therefore, the position of the second weakening line 22 does not overlap with the position of the absorbent article 3 of the package 1. Therefore, even if the package 1 is inflated by the absorbent article 3, the user can easily pick the vicinity of the second weakening line 22, for example, without being affected by the inflated portion. The second weakening line 22 can be easily separated. That is, the package 1 can be easily opened.

Further, in the present embodiment, as shown in FIGS. 1 to 4, the upper portion in the vertical direction T in each of the front surface portion 11, the rear surface portion 12, the right surface portion 13, and the left surface portion 14, for example, the upper surface portion 15. Alternatively, a handle portion 18 provided on the upper portion of the upper surface portion 15 may be further provided. Thereby, in the embodiment of partially opening the package 1, the upper surface portion 15 can be gripped by the handle portion 18 and the package 1 can be easily carried. Here, when carrying such a package 1, the weight of the absorbent article 3 may cause the remaining portion of the outer periphery of the upper surface portion 15 to be separated, and the upper surface portion 15 may be separated from the package body 1. .. However, since the package 1 has the above-mentioned structure, the partially bonded upper surface portion 15 does not separate.

Next, a method for manufacturing the package 1 according to the embodiment will be described.
FIG. 11 is a schematic view showing an example of a method for manufacturing a package according to an embodiment. In this manufacturing method, as an example, a manufacturing method of the gusset type package 1 will be described. However, this manufacturing method has a transport direction MD, a transverse direction CD, and a thickness direction TD (not shown) that are orthogonal to each other in the transport of materials in each step.

First, a packaging bag 2 capable of storing a plurality of absorbent articles 3 is formed. The method for forming the packaging bag 2 includes a side surface forming step and a weakening line forming step.

In the side surface forming step, both sides of the transverse CD in the tubular resin sheet member 50 (FIG. 11 (a)) extending along the transport direction MD are folded in a valley fold toward the inside of the transverse CD. .. As a result, the side surface forming step is folded between the front surface portion 11 and the rear surface portion 12 located on one side and the other side of the thickness direction TD, respectively, and the front surface portion 11 and the rear surface portion 12, and is folded on the right side of the transverse direction CD. And the right side portion 13 and the left side portion 14 located on the left side, respectively (FIG. 11 (b)). At this time, the front surface portion 11 and the rear surface portion 12 overlap in the thickness direction TD, and the right side portion and the right surface portion 13 of the front surface portion 11 and the rear surface portion 12 overlap in the thickness direction TD, and the front surface portion 11 The left side portion of the rear surface portion 12 and the left surface portion 14 overlap with each other in the thickness direction TD.

In the weakening line forming step, the weakening line forming blade (not shown) is pressed from one side of the front surface portion 11 and the rear surface portion 12 toward the other side (in the thickness direction TD). For example, the folded sheet member 50 is sandwiched between a roll having a weakening line forming blade and an anvil roll. As a result, the weakening line forming step forms the first weakening line 21 and the second weakening line 22 extending along the transverse direction CD on the front surface portion 11 and the rear surface portion 12. Along with this, at the same time, the first weakening line 21 and the second weakening line 21 and the second weakening line 21 extending along the transverse direction CD are located between the front surface portion 11 and the rear surface portion 12 and overlap the right surface portion 13 and the left surface portion 14 in the thickness direction TD. The weakening line 22 is formed. At this time, in the first weakening line 21 and the second weakening line 22, the relationship between the first weakening line 21 and the second weakening line 22 is 0 <d1 <d2, and the extension line L0 and the first weakening line 21. It is formed to satisfy the intersection with. It should be noted that the second weakening line 22 has a plurality of absorbent articles 3 when the upper surface portion 15 is gripped and the package 1 is lifted after the separation of at least one adjacent first weakening line 21 is performed. Due to the weight, the cutoff of the first weakening line 21 may be formed at a position where it cannot be reached even if it propagates to the corner portion 19.

When the packaging bag 2 to be formed includes the opening portion 20, the weakening line forming step is further separated from one side of the front surface portion 11 and the rear surface portion 12 toward the other side (in the thickness direction TD). Press the weak line forming blade (not shown). For example, the sheet member 50 that has been folded and formed with the first weakening wire 21 and the second weakening wire 22 is sandwiched between a roll having another weakening wire forming blade and an anvil roll. As a result, in the weakening line forming step, two vertical weakening lines 25 extending in the transport direction MD and a horizontal weakening line 24 extending in the transverse direction CD are formed on the front surface portion 11 and the rear surface portion 12. Along with this, at the same time, the weakening line forming step is located between the front surface portion 11 and the rear surface portion 12, and has two vertical lines extending in the transport direction MD on the right surface portion 13 and the left surface portion 14 overlapping the thickness direction TD. The weakening line 25 and the lateral weakening line 24 extending in the transverse direction CD are formed. Here, the position of the lower end of the transport direction MD on the two vertical weakening lines 25 is parallel to the transport direction MD in the plurality of absorbent articles 3 when the packaging bag 2 contains the plurality of absorbent articles 3. Two vertical weakening lines 25 and horizontal weakening lines 24 may be formed so as to be higher than the position of the lower end of the vertical direction T and lower than the position in the middle of the vertical direction T in the plurality of absorbent articles 3.

However, in that case, either the step of forming the first weakening line 21 and the second weakening line 22 or the step of forming the two vertical weakening lines 25 and the horizontal weakening line 24 may be performed first. , May be done at the same time. When performed at the same time, for example, the folded sheet member 50 is sandwiched between one roll having a weakening line forming blade and another weakening line forming blade and an anvil roll. At the same time, the handle portion 18 may be formed. As described above, the packaging bag 2 is formed (FIG. 11 (c)).

At this time, when the packaging bag 2 of FIG. 11C is cut at the boundary line CL between the rear surface portion 12 and the left surface portion 14 and unfolded, the result is as shown in FIG. Here, consider the region STA including the boundary line CL between the right surface portion 13 and the front surface portion 11. However, in the region STA, the width in the direction parallel to the bottom surface portion 16 along the surface of the packaging bag 2 (width direction W and depth direction D) is the same as the width of the right surface portion 13, and is along the surface of the packaging bag 2. The center in the direction parallel to the bottom surface portion 16 (width direction W and depth direction D) is a rectangular region which is a boundary line CL between the right surface portion 13 and the front surface portion 11. At this time, in the region STA, the second weakening line straddling the boundary line CL is axisymmetric with respect to the boundary line CL. Further, the first weakening line, the horizontal weakening line and the vertical weakening line of the front surface portion 11 adjacent to both sides of the boundary line CL and the first weakening line, the horizontal weakening line and the vertical weakening line of the right surface portion 13 are the boundary line CL. It is line symmetric with respect to. The same applies to the region STA (not shown) including the other boundary line CL. For example, in the region STA including the boundary line CL between the right surface portion 13 and the rear surface portion 12, the width thereof is the same as the width of the right surface portion 13, and the second weakening line straddling the boundary line CL, the adjacent rear surface portions 12 and the right. The first weakening line, the horizontal weakening line, and the vertical weakening line of the face portion 13 are line-symmetrical with respect to the boundary line CL. Further, in the region STA including the boundary line CL between the left surface portion 14 and the front surface portion 11, the width thereof is the same as the width of the left surface portion 14, and the second weakening line straddling the boundary line CL, the adjacent front surface portions 11 and the left The first weakening line, the horizontal weakening line, and the vertical weakening line of the face portion 14 are line-symmetrical with respect to the boundary line CL. Further, in the region STA including the boundary line CL between the left surface portion 14 and the rear surface portion 12, the width thereof is the same as the width of the left surface portion 14, and the second weakening line straddling the boundary line CL, the adjacent rear surface portions 12 and the left The first weakening line, the horizontal weakening line, and the vertical weakening line of the face portion 14 are line-symmetrical with respect to the boundary line CL.

After that, the bottom surface side portion of the formed packaging bag 2 is sealed by heat fusion to form the bottom surface portion 16. Next, a plurality of absorbent articles 3 are stored from the upper surface side of the packaging bag 2. Finally, the upper surface side portion of the packaging bag 2 is sealed by heat fusion to form the joint portion 17. As described above, the gusset type package 1 is formed.

In the present embodiment, as shown in FIGS. 1 to 4 (, FIG. 11), the package 1 may be a gusset type. In that case, the right surface portion 13 and the left surface portion 14 are portions folded in a valley fold on the right side and the left side in the width direction W between the front surface portion 11 and the rear surface portion 12, respectively. At that time, the second weakening line 22 of the corner portion 19 between the right surface portion 13 and the front surface portion 11 may have a shape symmetrical with respect to the boundary line CL between the right surface portion 13 and the front surface portion 11. Similarly, the second weakening line 22 of the corner portion 19 between the right surface portion 13 and the rear surface portion 12 may have a shape symmetrical with respect to the boundary line CL between the right surface portion 13 and the rear surface portion 12. The second weakening line 22 of the corner portion 19 between the left surface portion 14 and the front surface portion 11 may have a shape symmetrical with respect to the boundary line CL between the left surface portion 14 and the front surface portion 11. The second weakening line 22 of the corner portion 19 between the left surface portion 14 and the rear surface portion 12 may have a shape symmetrical with respect to the boundary line CL between the left surface portion 14 and the rear surface portion 12. As a result, the second weakening line 22 is separated from the corners 19 of each of the right surface portion 13 and the left surface portion 14 and each of the front surface portion 11 and the rear surface portion 12, so that each of the right surface portion 13 and the left surface portion 14 is separated. The second weakening line 22 of the above and the second weakening line 22 of each of the front surface portion 11 and the rear surface portion 12 can be broken together at the same time. As a result, both second weakening lines can be separated more easily, and the package 1 as a whole can be opened more easily.

In the present embodiment, as shown in FIGS. 1 to 4 (, FIG. 11), the package 1 may be a gusset type. In that case, the first weakening line 21 is formed at the same position as the upper edge 3TE1 of the plurality of absorbent articles 3 housed in the package 1 in the vertical direction T or at a position higher than the edge 3TE1. You may. In that case, the second weakening line 22 is located above the first weakening line 21 in the vertical direction T. Therefore, the position of the second weakening line 22 in the package 1 does not overlap with the position of the stored absorbent article 3. Therefore, even if the package 1 is inflated by the stored absorbent article 3, the user can easily, for example, in the vicinity of the second weakening line 22 without being affected by the inflated portion. By picking it up, the second weakening line 22 can be easily separated. That is, the package can be easily opened.

[Second Embodiment]
Next, the second embodiment will be described. In the present embodiment, the package 1 (packaging bag 2) includes an opening portion 20 on at least one of the plurality of side surface portions. Hereinafter, the differences from the first embodiment will be mainly described.

The packaging body 1 (packaging bag 2) is provided with an opening portion 20 on at least one of a plurality of side surface portions. As shown in FIGS. 1 to 4, the opening portion 20 extends along the vertical direction T, and has two vertical weakening lines 25 arranged at intervals in the width direction W or the depth direction D, and the width direction W or. It includes a horizontal weakening line 24 extending along the depth direction D and connecting the upper ends of the vertical weakening lines 25 in the vertical direction T to each other. Here, the weakening lines such as the vertical weakening line 25 and the horizontal weakening line 24 are a portion through which the sheet member of the packaging bag 2 is penetrated in the thickness direction or a portion thinly cut in the thickness direction and half-cut (hereinafter referred to as a half-cut portion). A plurality of "weakened parts") are intermittently arranged in a predetermined direction, and are exemplified by perforations. By pulling the portions on both sides of the weakening line so as to separate them from each other, they can be easily separated from each other along the weakening line. Then, by separating the horizontal weakening line 24 and the two vertical weakening lines 25, the opening portion 20 can be opened and the absorbent article 3 can be taken out.

In the present embodiment, the opening portion 20 is included in each of the front surface portion 11, the rear surface portion 12, the right surface portion 13, and the left surface portion 14. Each of the front surface portion 11 and the rear surface portion 12 extends along the vertical direction T, two vertical weakening lines 25 arranged at intervals in the width direction W, and two extending along the width direction W. Includes a horizontal weakening line 24 that connects the upper ends of the vertical weakening line 25 in the vertical direction T. On the other hand, each of the right surface portion 13 and the left surface portion 14 extends along the vertical direction T, two vertical weakening lines 25 arranged at intervals in the depth direction D, and two extending along the depth direction D. Includes a horizontal weakening line 24 that connects the upper ends of the vertical weakening line 25 in the vertical direction T.

In the opening portion 20, the positions H1D and H2D of the lower end of the vertical direction T on the two vertical weakening lines 25 are higher than the position HAD of the lower end 3TE2 of the vertical direction T in the plurality of absorbent articles 3, and the plurality of absorbent articles It is lower than the position HAM in the middle of the vertical direction T in 3. Therefore, when the opened portion 20 is opened, the lower portion of the absorbent article 3 in the vertical direction T remains covered with the packaging bag 2, and the portion above the side portion (half or more portion). Will be exposed.

For example, as shown in FIG. 2, the position H1D of the lower end of the vertical direction T on the two vertical weakening lines 25 of the front surface portion 11 is higher than the position HAD of the lower end 3TE2 of the vertical direction T in the plurality of absorbent articles 3. , Lower than the position HAM in the middle of the vertical direction T in the plurality of absorbent articles 3. Here, the distance between the position H1D at the lower end of the vertical weakening line 25 and the position HAD at the lower end 3TE2 of the absorbent article 3 is set to d11 (> 0), and the position HAD at the lower end 3TE2 of the absorbent article 3 and the upper end 3TE1. Assuming that the distance from the position HAU is dA0 (> 0), d11 <dA0 / 2. The same applies to the rear surface portion 12. Further, in the present embodiment, as shown in FIG. 3, the position H2D of the lower end of the vertical direction T on the two vertical weakening lines 25 of the right surface portion 13 is the lower end 3TE2 of the vertical direction T in the plurality of absorbent articles 3. It is higher than the position HAD and lower than the position HAM in the middle of the vertical direction T in the plurality of absorbent articles 3. Here, if the distance between the position H2D at the lower end of the vertical weakening line 25 and the position HAD at the lower end 3TE2 of the absorbent article 3 is d21 (> 0), d21 <dA0 / 2. The same applies to the left surface portion 14. However, in the present embodiment, as shown in FIGS. 2 and 3, among the plurality of absorbent articles 3 stacked in a plurality of stages in the vertical direction T, the plurality of absorbent articles 3 in the uppermost stage are opened. The portion 20 is formed.

Further, in the present embodiment, the opening portion 20 is formed so as to cover a part of the upper surface portion (including the upper end 3TE1) of the plurality of absorbent articles 3 in the state of being stored in the packaging bag 2 in the vertical direction T. There is. In this case, the lateral weakening line 24 of the opening portion 20 is formed in the portion 20U of the opening portion 20 that covers a part of the upper surface portion (including the upper end 3TE1) of the vertical direction T in the plurality of absorbent articles 3. Has been done. Therefore, when the opened portion 20 is opened and the portion 20U is removed, a part of the upper surface portion (including the upper end 3TE1) of the absorbent article 3 in the vertical direction T is exposed.

For example, as shown in FIGS. 1 and 2, the opening portion 20 of the front surface portion 11 includes a portion 20U that covers a part of the upper surface portion (including the upper end 3TE1) of the vertical direction T in the plurality of absorbent articles 3. There is. In this case, the lateral weakening line 24 of the opening portion 20 of the front surface portion 11 is formed in the portion 20U of the opening portion 20. Here, assuming that the distance between the position H1U at the lower end of the lateral weakening line 24 and the position HAU at the upper end 3TE1 of the absorbent article 3 is d12, d12> 0. The same applies to the rear surface portion 12. Further, in the present embodiment, as shown in FIGS. 1 and 3, the opening portion 20 of the right surface portion 13 covers a part of the upper surface portion (including the upper end 3TE1) of the plurality of absorbent articles 3 in the vertical direction T. Includes portion 20U. In this case, the lateral weakening line 24 of the opening portion 20 of the right surface portion 13 is formed in the portion 20U of the opening portion 20. Here, assuming that the distance between the position H2U at the lower end of the lateral weakening line 24 and the position HAU at the upper end 3TE1 of the absorbent article 3 is d22, d22> 0. The same applies to the left surface portion 14. The positions H1U and H2U are the positions of the lower ends of the horizontal weakening line 24 and also the positions of the upper ends of the vertical weakening line 25.

The package 1 (packaging bag 2) may or may not be provided with the first weakening line 21 and the second weakening line 22 in each of the front surface portion 11, the rear surface portion 12, the right surface portion 13, and the left surface portion 14. May be good. When the package 1 (packaging bag 2) is provided with the first weakening wire 21 and the second weakening wire 22 on each side surface portion, the first weakening wire 21 and the second weakening wire 22 are, for example, in the first embodiment. As stated.

FIG. 12 is a schematic view showing a state in which the package 1 according to the embodiment is opened by the front surface portion 11 or the left surface portion 14. As shown in FIG. 12A, in the front surface portion 11 of the package 1, the lateral weakening line 24 of the opening portion 20 is separated to form the horizontal cutting line 24a, and subsequently, the two vertical weakening lines 25 are separated.
