Disclosure of Invention

Problems to be solved by the invention

In the package as described above, the plurality of folded absorbent articles spread inside the package, and thereby a force pushing the package outward acts on the package. The front surface portion, the back surface portion, the 1 st side surface portion, and the 2 nd side surface portion of the package are stretched by the force, and the slack is reduced. Therefore, in the case where the easy-tear lines are formed on the front surface portion, the back surface portion, and the 1 st side surface portion of the package as in the package described above, the user may feel that it is difficult to pinch the package in the vicinity of the easy-tear lines and to open the package.

Accordingly, an object of the present disclosure is to provide a package and a packaged product that can be easily opened.

Means for solving the problems

One aspect provides a package made of a synthetic resin, the package including a front surface portion, a back surface portion, a 1 st side surface portion, a 2 nd side surface portion, a bottom surface portion, and a top surface portion, and a plurality of absorbent articles being contained therein. A fracture line is formed on the top surface portion of the package, the fracture line being more easily fractured than other portions of the top surface portion, the fracture line including: a 1 st fracture line extending in a front-rear direction intersecting the front surface portion and the back surface portion; a 2 nd fracture line connected to one end of the 1 st fracture line and extending in a left-right direction intersecting the 1 st side surface part and the 2 nd side surface part; and a 3 rd fracture line connected to the other end of the 1 st fracture line and extending in the left-right direction, wherein a ratio of a length of at least one of the 2 nd fracture line and the 3 rd fracture line to a width of the front portion in the left-right direction is 60% to 90%.

In the package according to the above aspect, the fracture line is formed in the top surface portion. The spreading force of the plurality of absorbent articles is less likely to act on the top surface portion than the front surface portion, the back surface portion, the 1 st side surface portion, and the 2 nd side surface portion, and therefore slack is likely to occur in the top surface portion. Therefore, the user can easily open the package by pinching the top surface portion and tearing it from the fracture line. In this case, in the package of the present aspect, the ratio of the length of at least one of the 2 nd breaking line and the 3 rd breaking line to the width of the front portion in the width direction is 60% or more and 90% or less, and therefore, an opening portion having a relatively large width can be formed in the package, and as a result, the absorbent article can be easily taken out from the opened package. Further, by opening the package along the 1 st fracture line, the 2 nd fracture line, and the 3 rd fracture line, a part of the top surface portion can be used as the lid portion. By covering the opening with the lid portion, it is possible to prevent foreign matter from entering the package after opening, and therefore, the absorbent article can be stored sanitarily.

In one aspect, a ratio of a length of at least one of the 2 nd fracture line and the 3 rd fracture line to a width of the front portion in the left-right direction may be 60% or more and 70% or less. By setting the ratio of the length of the 2 nd or 3 rd fracture line to the width of the front face portion to 60% or more and 70% or less, the absorbent article can be easily taken out from the opened package while maintaining the strength of the package.

In one aspect, the top surface portion may include: a 1 st top surface part connected to the 1 st side surface part; a 2 nd top surface part connected to the front surface part; a 3 rd top surface part connected to the back surface part; and a 4 th top surface portion connected to the 2 nd side surface portion, wherein the 1 st fracture line is formed on the 1 st top surface portion, the 2 nd fracture line is formed on the 2 nd top surface portion, and the 3 rd fracture line is formed on the 3 rd top surface portion. By opening the package along the fracture line formed continuously on the 1 st top surface portion, the 2 nd top surface portion, and the 3 rd top surface portion, an opening portion can be formed in the upper portion of the package, and the absorbent article can be taken out from the opening portion.

In one aspect, the 1 st top surface portion may include: a welding region in which the 1 st top surface portion is welded to the 2 nd and 3 rd top surface portions in a state of being folded inward in the left-right direction; and a non-welded region in which the 1 st top surface portion is not welded to the 2 nd top surface portion and the 3 rd top surface portion, and the 1 st fracture line is formed in the non-welded region of the 1 st top surface portion. Further, the 1 st fracture line may be formed at a position closer to a boundary between the 1 st side surface part and the 1 st top surface part than the welding region of the 1 st top surface part. In this aspect, the force is applied to the 1 st fracture line by pinching and pulling up the folded-in portion of the 1 st top surface portion with a hand, so that the package can be easily opened with the 1 st fracture line as a starting point.

In one aspect, the 1 st fracture line and the 2 nd fracture line may be formed at positions not overlapping each other when viewed from the front-rear direction. In this case, it is possible to prevent the package from being unintentionally opened when the package is carried.

In one embodiment, the apparatus may further include a mark indicating a position of the 1 st fracture line, and the mark may be disposed on the bottom surface side of the 1 st fracture line. In this aspect, by forming the mark at a position closer to the bottom surface portion side than the 1 st fracture line, the mark can be easily recognized, and accordingly, the position of the 1 st fracture line can be easily recognized.

In one aspect, a handle portion serving as a handle may be formed on the top surface portion, and an end portion of the 2 nd break line and an end portion of the 3 rd break line may be disposed between a pair of end edges of the handle portion in the left-right direction. In this embodiment, when the package is lifted by holding the handle portion, the force acting on the handle portion is not easily transmitted to the end portion of the 2 nd fracture line and the end portion of the 3 rd fracture line. Therefore, the package can be prevented from being opened unintentionally when the package is carried.

In one aspect, a handle portion serving as a handle may be formed in the top surface portion, and the end portion of the 2 nd fracture line and the end portion of the 3 rd fracture line may extend beyond end edges of the handle portion in the left-right direction to the 2 nd side surface portion side in the left-right direction. In this aspect, when the handle portion is lifted, the force is easily transmitted to the end portion of the 2 nd fracture line and the end portion of the 3 rd fracture line, and therefore the package can be opened with a small force starting from the end edge of the 2 nd fracture line and the end edge of the 3 rd fracture line.

The package of one embodiment may be made of a material having a stiffness of 100mm or less. By setting the stiffness of the package to 100mm or less, the lid portion formed by opening the package along the 1 st fracture line, the 2 nd fracture line, and the 3 rd fracture line is flexibly deformed, and the lid portion can be easily opened and closed.

In one embodiment, the 1 st, 2 nd and 3 rd fracture lines are easy-to-tear lines including a cut portion and a non-cut portion, and a ratio of a length of the cut portion of the 1 st fracture line to a length of the non-cut portion may be greater than a ratio of a length of the cut portion of the 2 nd fracture line to a length of the non-cut portion and a ratio of a length of the cut portion of the 3 rd fracture line to a length of the non-cut portion. Since the ratio of the length of the cut portion of the 1 st fracture line to the length of the uncut portion is large, the 1 st fracture line is easily fractured, and thus the package can be easily opened starting from the 1 st fracture line.

In one embodiment, the 1 st breaking line, the 2 nd breaking line, and the 3 rd breaking line may be easy-to-tear lines, and burrs resulting from the formation of the easy-to-tear lines may be formed on the top surface portion and protrude from the inner surface side toward the outer surface side of the top surface portion. In this aspect, the burrs protrude toward the outer surface side of the top surface portion, so that the position of the broken line can be recognized by the tactile sensation of the burrs, and the broken line can be easily found.

A packaged product of the present invention includes: a plurality of absorbent articles; and a package made of a synthetic resin, the package including a front surface portion, a back surface portion, a 1 st side surface portion, a 2 nd side surface portion, a bottom surface portion, and a top surface portion, the plurality of absorbent articles being contained therein, a fracture line being formed in the package at a position closer to the top surface portion side than an uppermost portion of the plurality of absorbent articles in a vertical direction intersecting the bottom surface portion and the top surface portion, the fracture line being more easily fractured than other portions of the package, the fracture line including: a 1 st fracture line extending in a front-rear direction intersecting the front surface portion and the back surface portion; a 2 nd fracture line extending from one end of the 1 st fracture line in a left-right direction intersecting the 1 st side surface part and the 2 nd side surface part; and a 3 rd fracture line extending in the left-right direction from the other end of the 1 st fracture line, wherein a ratio of a length of at least one of the 2 nd fracture line and the 3 rd fracture line to a width of the front portion in the left-right direction is 60% or more and 90% or less.

In the packaged product according to the above aspect, the fracture line is formed in the top surface portion of the package. The spreading force of the plurality of absorbent articles is less likely to act on the top surface portion than the front surface portion, the back surface portion, the 1 st side surface portion, and the 2 nd side surface portion, and therefore slack is likely to occur in the top surface portion. Therefore, the user can easily open the package by pinching the top surface portion and tearing it from the fracture line. Further, the absorbent article can be taken out from the opening formed by opening the package along the fracture line. In this case, in the packaged product of this aspect, the ratio of the length of one of the 2 nd and 3 rd fracture lines to the width of the front portion in the width direction is 60% or more and 90% or less, and therefore, an opening portion having a relatively large width can be formed, and as a result, the absorbent article can be easily taken out from the opened package. Further, by opening the package along the 1 st breaking line, the 2 nd breaking line, and the 3 rd breaking line, a part of the top surface portion can be used as the lid portion. By covering the opening with the lid portion, it is possible to prevent foreign matter from entering the package after opening, and therefore, the absorbent article can be stored sanitarily.

In one aspect, each of the plurality of absorbent articles may have a vertically long absorbent core, the absorbent core may be provided with a stiffness reducing portion extending in a longitudinal direction of the absorbent core and having a lower stiffness than other portions of the absorbent core, and the plurality of absorbent articles may be arranged in the package in a state where the absorbent core is folded in a lateral direction of the package in a short side direction of the absorbent core. As described above, by forming the stiffness reduced portion in the absorbent core of the absorbent article, the bendability in the width direction of the absorbent article is improved. Therefore, the absorbent article can be easily taken out from the opening of the package in a folded state.

Detailed Description

Embodiments of the present disclosure are described below with reference to the drawings. In the following description, the same or corresponding elements are denoted by the same reference numerals, and a repetitive description thereof will not be repeated. In the drawings, a part may be drawn in a simplified or exaggerated manner for easy understanding, and the dimensional ratio is not limited to the dimensional ratio shown in the drawings.

A packaged product according to an embodiment will be described below. Fig. 1 is a perspective view of a packaged product 1 of an embodiment. Fig. 2 is a front view of the packaged product 1, and fig. 3 is a left side view of the packaged product 1. For convenience of explanation, the left-right direction X, the front-back direction Y, and the up-down direction Z are shown in the drawings to be orthogonal to each other. The left-right direction X is a direction intersecting (orthogonal to) a left side surface 13 and a right side surface 14 of the package 3 described later, and the front-back direction Y is a direction intersecting (orthogonal to) a front surface 11 and a back surface 12 of the package 3. The vertical direction Z is a direction perpendicular to the horizontal direction X and the front-rear direction Y, and intersects the bottom surface portion 15 and the top surface portion 16.

The packaged product 1 includes a plurality of absorbent articles 2 and a package 3. As shown in fig. 2 and 3, a plurality of absorbent articles 2 are housed in a package 3. The absorbent article 2 is an article having an absorbent body that absorbs body fluids such as urine, blood, and sweat. Examples of the absorbent article 2 include diapers, toilet training pants, incontinence pads, sanitary napkins, and pet diapers. Examples of the diaper include a pants-type or belt-type disposable diaper.

Fig. 4 is a plan view showing a tape-type disposable diaper used as an example of the absorbent article 2. In fig. 4, the absorbent article 2 is shown in an extended state in which no gathers are formed. The absorbent article 2 shown in fig. 4 is a disposable diaper for adults. The absorbent article 2 may be a disposable diaper for children or a disposable diaper for pets. As shown in fig. 4, the absorbent article 2 extends in a transverse direction W disposed along the waistline direction of the wearer and a longitudinal direction L orthogonal to the transverse direction W. The longitudinal direction L is a direction connecting the back side from the abdominal side of the wearer in a worn state.

As shown in fig. 4, the absorbent article 2 includes a main body portion 100, a pair of fastening flaps 120, and a target tape portion 130. The main body 100 is for absorbing excreta and includes a front sheet 110, a back sheet 112 and an absorbent core 113. The topsheet 110 is disposed on the front surface side of the absorbent article 2 and constitutes a surface that is in contact with the skin of the wearer. The top sheet 110 has liquid permeability for allowing body fluid to pass through to the absorbent core 113 side. The top sheet 110 includes a center sheet 110a located at the center in the transverse direction W, and side sheets 110b covering both side portions of the center sheet 110a in the transverse direction W.

The side sheet 110b is provided with a pair of

elastic members

115 and 116 extending in the longitudinal direction L. The pair of elastic members 115 are disposed on both sides of the main body 100 in the transverse direction W in an elongated state in the longitudinal direction L. The pair of elastic members 115 contract in the longitudinal direction L, whereby the side end edges in the transverse direction W of the main body portion 100 are brought into close contact with the leg circumferences of the wearer, and the fit of the absorbent article 2 is improved. The pair of elastic members 116 is provided at a position further inward than the pair of elastic members 115 in the lateral direction W. The pair of elastic members 116 are attached to the side sheet 110b of the main body portion 100 in an elongated state in the longitudinal direction L. When the absorbent article 2 is worn, the pair of elastic members 116 contract in the longitudinal direction L, and thereby parts of the side sheet 110b stand up toward the wearer side to form a pair of leakage preventing cuffs. By forming a pair of leakage-proof cuffs, the leakage of excrement along the surface of the surface sheet 110 is prevented.

The pair of hook and loop fastener tabs 120 are disposed near the front end edge in the longitudinal direction L of the main body 100 and extend outward in the transverse direction W. Each of the pair of hook and loop fasteners 120 includes a joining portion 122 formed of a mechanical fastener or the like, and the joining portion 122 is configured to be joinable to the target tape portion 130. The target tape portion 130 is formed on the back side of the body portion 100 in the vicinity of the back-side end edge in the longitudinal direction L of the body portion 100. The absorbent article 2 is worn on the wearer by attaching the pair of fastening flaps 120 to the target belt portion 130.

The absorbent core 113 is disposed between the front sheet 110 and the back sheet 112. The absorbent core 113 contains, for example, ground pulp and a polymeric absorbent (SAP), and absorbs urine of a wearer. Further, the upper and lower surfaces of the absorbent core 113 may also be covered by a core wrap. The absorbent core 113 is disposed at the center in the lateral direction W of the main body 100. The length of the absorbent core 113 in the longitudinal direction L is longer than the width of the absorbent core 113 in the transverse direction W. That is, the absorbent core 113 has a longitudinal shape with the longitudinal direction L being the longitudinal direction and the lateral direction W being the lateral direction.

The absorbent core 113 is provided with a plurality of stiffness reducing sections 131 extending in the longitudinal direction of the absorbent core 113. The stiffness reduced section 131 is, for example, a slit or a groove formed in the absorbent core 113, and has a lower stiffness than other portions of the absorbent core 113. The plurality of rigidity reducing portions 131 are formed near the central portion in the lateral direction W of the main body portion 100. Further, only one absorbent core 113 may be formed in the main body portion 100, the one absorbent core 113 continuously extending along the longitudinal direction L in the vicinity of a central portion in the transverse direction W of the main body portion 100. By forming the stiffness reducing portion 131 extending in the longitudinal direction L in the absorbent core 113, the stiffness of the central portion in the transverse direction W of the absorbent core 113 is reduced, and as a result, the bendability in the transverse direction W of the main body portion 100 is improved.

As shown in fig. 2 and 3, the plurality of absorbent articles 2 are stored in a folded state inside the package 3. For example, the absorbent article 2 is stored in the package 3 in a state in which the side sheet 110b is folded back inward in the transverse direction W and then is folded back in three along the longitudinal direction L. The width in the transverse direction W of the absorbent article 2 folded in this way substantially coincides with the width in the left-right direction X of the front portion 11 of the package 3 and the width in the left-right direction X of the back portion 12, and the length in the longitudinal direction L of the folded absorbent article 2 substantially coincides with the height in the up-down direction Z of the front portion 11 of the package 3 and the height in the up-down direction Z of the back portion 12. The plurality of absorbent articles 2 thus folded are stacked in the front-rear direction Y in a state of being folded in the lateral direction W, i.e., the short side direction of the absorbent core 113, toward the left-right direction X of the package 3, and are stored in the package 3.

The package 3 houses a plurality of absorbent articles 2. As shown in fig. 1, the package 3 includes a front portion 11, a back portion 12, a left side portion (1 st side portion) 13, a right side portion (2 nd side portion) 14, a bottom portion 15, and a top portion 16. The package 3 has a substantially rectangular parallelepiped shape, and defines a space for accommodating the plurality of absorbent articles 2. The front portion 11, the back portion 12, the left side portion 13, the right side portion 14, the bottom portion 15, and the top portion 16 of the package 3 are formed of a sheet member made of synthetic resin such as polyethylene, polypropylene, or polyethylene terephthalate. In one embodiment, the package 3 may be formed of a sheet having a stiffness of 100mm or less as measured by method a (45 ° cantilever method) according to JIS L1096: 2010.

Further, since the package 3 is made of a material that is easily deformable, when a plurality of absorbent articles 2 are stored inside the package 3, the package 3 may not have a rectangular parallelepiped shape in a strict sense. For example, there are cases where: a force pushing outward is applied to the front surface portion 11, the back surface portion 12, the left side surface portion 13, and the right side surface portion 14 from the plurality of absorbent articles 2, and a part or all of the surface of the package 3 is curved or has irregularities.

The front surface portion 11 and the back surface portion 12 of the package 3 face each other in the front-rear direction Y of the package 3, and the left side surface portion 13 and the right side surface portion 14 face each other in the left-right direction X of the package 3. The bottom portion 15 is connected to the front portion 11, the back portion 12, the left side portion 13, and the right side portion 14 on the bottom surface side of the package 3, and closes the bottom of the package 3. The top portion 16 is connected to the front portion 11, the back portion 12, the left side portion 13, and the right side portion 14 on the top surface side of the package 3, and closes the upper portion of the package 3. In the following description, the front portion 11 side of the package 3 is referred to as a front side, the back portion 12 side of the package 3 is referred to as a rear side, the left side portion 13 side of the package 3 is referred to as a left side, the right side portion 14 side of the package 3 is referred to as a right side, the bottom portion 15 side of the package 3 is referred to as a lower side, and the top portion 16 side of the package 3 is referred to as an upper side. The front surface 11, the back surface 12, the left side surface 13, and the right side surface 14 of each surface of the package 3 may be collectively referred to as a side surface 10 (see fig. 5).

A fracture line 22 is formed in the top surface portion 16 of the package 3, and the fracture line 22 is more easily fractured than other portions of the top surface portion 16. Therefore, the fracture line 22 is formed at a position above the uppermost portion 2a of the plurality of absorbent articles 2 stored in the package 3 (see fig. 2 and 3). The break line 22 includes: a 1 st fracture line 23 extending in the front-rear direction Y; a 2 nd fracture line 24 extending in the left-right direction X from one end of the 1 st fracture line 23; and a 3 rd fracture line 25 extending in the left-right direction X from the other end of the 1 st fracture line 23. Details of the break line 22 will be described later.

Fig. 5 is a developed view of the package 3 cut along a boundary between the back surface portion 12 and the right side surface portion 14. As shown in fig. 5, the front surface 11, the back surface 12, the left side 13, the right side 14, the bottom surface 15, and the top surface 16 of the package 3 are each rectangular.

As shown in fig. 5, the bottom surface portion 15 includes a 1 st bottom surface portion 31, a 2 nd bottom surface portion 32, a 3 rd bottom surface portion 33, and a 4 th bottom surface portion 34. The 1 st, 2 nd, 3 rd and 4 th

bottom surface portions

31, 32, 33 and 34 are respectively rectangular in shape. The 1 st bottom surface portion 31 is connected to the left side surface portion 13, and the 2 nd bottom surface portion 32 is connected to the front surface portion 11. The 3 rd bottom portion 33 is connected to the back portion 12, and the 4 th bottom portion 34 is connected to the right side portion 14. The 1 st, 2 nd, 3 rd, and 4 th

bottom surface parts

31, 32, 33, and 34 are welded at the welding part M1 to be joined to each other. The welded portion M1 is a band-shaped region extending in a direction parallel to a boundary between the side surface portion 10 and the bottom surface portion 15.

The top surface portion 16 includes a 1 st top surface portion 41, a 2 nd top surface portion 42, a 3 rd top surface portion 43, and a 4 th top surface portion 44. The 1 st, 2 nd, 3 rd and 4 th

top surface parts

41, 42, 43 and 44 have a rectangular shape, respectively. The 1 st top surface portion 41 is continuous with the left side surface portion 13 in the vertical direction Z, and the 2 nd top surface portion 42 is continuous with the front surface portion 11 in the vertical direction Z. The 3 rd top surface portion 43 is continuous with the back surface portion 12 in the vertical direction Z, and the 4 th top surface portion 44 is continuous with the right side surface portion 14 in the vertical direction Z. That is, the 1 st top surface portion 41 is connected to the left side surface portion 13, the 2 nd top surface portion 42 is connected to the front surface portion 11, the 3 rd top surface portion 43 is connected to the rear surface portion 12, and the 4 th top surface portion 44 is connected to the right side surface portion 14. The 1 st, 2 nd, 3 rd and 4 th

top surface portions

41, 42, 43 and 44 are welded and joined to each other along the welded portions M2 and M3. The welded portion M2 and the welded portion M3 are band-shaped regions extending in a direction parallel to the boundary between the side surface portion 10 and the top surface portion 16. The welded portion M2 and the welded portion M3 extend in the left-right direction X when viewed from the front-rear direction Y. The welded portion M2 and the welded portion M3 are parallel to each other, and the welded portion M3 is formed closer to the bottom surface portion 15 than the welded portion M2.

As shown in fig. 1 and 5, the top surface portion 16 has a welded region 18 and a non-welded region 20. The welded region 18 is a region where the 1 st top surface portion 41, the 2 nd top surface portion 42, the 3 rd top surface portion 43, and the 4 th top surface portion 44 are joined, and is a band-shaped region including the welded portion M2 and the welded portion M3 of the top surface portion 16. The welding region 18 is formed in a band shape extending in the left-right direction X above the top surface portion 16. Therefore, as shown in fig. 5, the welding region 18 is formed to cross the 1 st, 2 nd, 3 rd, and 4 th

top surface portions

41, 42, 43, and 44. On the other hand, the non-welding region 20 is a region where the 1 st top surface portion 41, the 2 nd top surface portion 42, the 3 rd top surface portion 43, and the 4 th top surface portion 44 are not joined. The non-welded region 20 is formed on the bottom surface portion 15 side of the welded region 18. Therefore, the 1 st, 2 nd, 3 rd, and 4 th

top surface portions

41, 42, 43, and 44 locally include the welding region 18 and the non-welding region 20, respectively.

Here, as shown in fig. 1, the 1 st top surface portion 41 and the 4 th top surface portion 44 are welded to the 2 nd top surface portion 42 and the 3 rd top surface portion 43 in a state of being folded in a valley manner toward the inside in the left-right direction X of the package 3 in the welding region 18. Therefore, the 2 nd top surface portion 42 and the 3 rd top surface portion 43 are welded to each other at the center portion of the package 3 in the left-right direction X. Further, the 1 st top surface portion 41 is fusion-bonded to the 2 nd top surface portion 42 and the 3 rd top surface portion 43 in a valley-folded state on the left side in the left-right direction X of the package 3, and the 4 th top surface portion 44 is fusion-bonded to the 2 nd top surface portion 42 and the 3 rd top surface portion 43 in a valley-folded state on the right side in the left-right direction X of the package 3. By welding the 1 st top surface portion 41 and the 4 th top surface portion 44 in this manner, as shown in fig. 1, the non-welded region 20 of the 1 st top surface portion 41 and the non-welded region 20 of the 4 th top surface portion 44 are folded inward in the left-right direction X. Therefore, when the package 3 is viewed from above, the non-welding region 20 of the 1 st top surface portion 41 and the non-welding region 20 of the 4 th top surface portion 44 are blocked by the 2 nd top surface portion 42 and the 3 rd top surface portion 43 and are not visible.

A handle portion 19 serving as a handle for the packaged product 1 is formed in the welding region 18 of the top surface portion 16. The handle portion 19 is formed by providing a substantially inverted U-shaped cutout near the center of the welding region 18 in the left-right direction X. By providing such a cutout, a cut piece 19a having a lower end connected to the top surface portion 16 is formed, and by folding back the cut piece 19a in the front-rear direction Y, a substantially elliptical opening is formed in the welding region 18. The handle portion 19 is an edge portion of the substantially elliptical opening side of the welding region 18. The user can lift the packaged product 1 by putting his hand into the opening formed in the welding area 18 and gripping the handle portion 19. In addition, the opening may be formed by cutting out a part of the welding region 18 in a ring shape without forming the cut piece 19a in the welding region 18. In this case, it is also possible to carry the packaged product 1 by putting a hand into the opening.

A fracture line 22 is formed in the non-welded region 20 of the top surface portion 16. The fracture line 22 is a portion that is more easily fractured than other portions of the top surface portion 16, and is, for example, a tear line including a cut portion and a non-cut portion. The fracture lines 22 include a 1 st fracture line 23, a 2 nd fracture line 24, and a 3 rd fracture line 25. The 1 st fracture line 23 is formed on the 1 st top surface portion 41 and extends in the front-rear direction Y. More specifically, the 1 st fracture line 23 extends linearly across the 1 st top surface portion 41 between a boundary line BL1 and a boundary line BL2, the boundary line BL1 being a boundary line between the 1 st top surface portion 41 and the 2 nd top surface portion 42, and the boundary line BL2 being a boundary line between the 1 st top surface portion 41 and the 3 rd top surface portion 43. The 1 st fracture line 23 extends parallel to the boundary BL3 between the 1 st top surface portion 41 and the left side surface portion 13, and is formed closer to the boundary BL3 than the welding region 18 (welding portion M3).

The 2 nd fracture line 24 is formed on the 2 nd top surface portion 42 and extends in the left-right direction X. The 2 nd breaking line 24 is connected to one end of the 1 st breaking line 23 and extends linearly in the left-right direction X of the package 3. More specifically, one end of the 2 nd fracture line 24 is connected to one end of the 1 st fracture line 23 at the boundary BL1, and the other end of the 2 nd fracture line 24 is disposed in front of the boundary BL4 between the 2 nd top surface portion 42 and the 4 th top surface portion 44 (on the boundary BL1 side of the boundary BL 4). As shown in fig. 5, the ratio of the length L1 of the 2 nd fracture line 24 to the width W1 of the front portion 11 in the left-right direction X is 60% or more and 90% or less. In one embodiment, the ratio of the length L1 of the 2 nd fracture line 24 to the width W1 of the front portion 11 in the left-right direction X may be 60% to 70%. That is, no break line is formed in the right region of the 2 nd top surface portion 42 (the region between the other end of the 2 nd break line 24 and the boundary line BL 4).

The 3 rd fracture line 25 is formed on the 3 rd top surface portion 43 and extends in the left-right direction X. The 3 rd breaking line 25 extends linearly along the left-right direction X of the package 3 from the other end of the 1 st breaking line 23. More specifically, one end of the 3 rd broken line 25 is connected to the other end of the 1 st broken line 23 at the boundary BL2, and the other end of the 3 rd broken line 25 is disposed in front of the boundary BL5 between the 3 rd top surface portion 43 and the 4 th top surface portion 44 (on the boundary BL2 side with respect to the boundary BL 5). The ratio of the length L2 of the 3 rd fracture line 25 to the width W2 of the back surface portion 12 in the left-right direction X is 60% to 90%. In one embodiment, the ratio of the length L2 of the 3 rd fracture line 25 to the width W2 of the back surface portion 12 in the left-right direction X may be 60% or more and 70% or less. That is, no break line is formed in the right region of the 3 rd top surface portion 43 (the region between the other end of the 3 rd break line 25 and the boundary line BL 5). The length L2 of the 3 rd fracture line 25 and the width W2 of the back surface portion 12 may be the same as the length L1 of the 2 nd fracture line 24 and the width W1 of the front surface portion 11, respectively.

As described above, the 1 st break line 23, the 2 nd break line 24, and the 3 rd break line 25 are continuously formed on the 1 st top surface portion 41, the 2 nd top surface portion 42, and the 3 rd top surface portion 43, and the break line 22 is formed in a substantially letter U shape with the right side opened when the package 3 is viewed from above. On the other hand, the fracture line 22 is not formed in the 4 th top surface portion 44. When the 1 st breaking line 23, the 2 nd breaking line 24, and the 3 rd breaking line 25 are the easy-to-tear lines, burrs resulting from the formation of the easy-to-tear lines may be formed on the top surface portion 16 of the package 3, and the burrs may protrude from the inner surface side toward the outer surface side of the top surface portion 16. The existence of burrs at the formation positions of the 1 st breaking line 23, the 2 nd breaking line 24, and the 3 rd breaking line 25 makes it possible to easily find the positions of the breaking lines 22 by the feel of the burrs.

In one embodiment, when package 3 is viewed from front-rear direction Y, 1 st line of

disruption

23 and 2 nd line of disruption 24 may be formed at positions not overlapping each other, and 1 st line of

disruption

23 and 3 rd line of disruption 25 may be formed at positions not overlapping each other. For example, when the 1 st, 2 nd, 3 rd, and 4 th

top surface portions

41, 42, 43, and 44 are welded, the 1 st, 2 nd, 3 rd, and 4 th

top surface portions

41, 42, 43, and 44 may be stretched to place the 1 st and 2

nd break lines

23 and 24, and the 1 st and 3

rd break lines

23 and 25 at different positions in the vertical direction Z.

In one embodiment, the other end of the 2 nd break line 24 and the other end of the 3 rd break line 25 may extend to the right side (the 4 th top surface portion 44 side) beyond the end edge 19b of the handle portion 19 on the 4 th top surface portion 44 side in the left-right direction X. The other end of the 2 nd fracture line 24 and the other end of the 3 rd fracture line 25 extend beyond the handle portion 19 to the 4 th top surface portion 44 side, and therefore, when the handle portion 19 is lifted up, force is easily transmitted to the other end of the 2 nd fracture line 24 and the other end of the 3 rd fracture line 25, and the 2 nd fracture line 24 and the 3 rd fracture line 25 can be fractured with a small force.

In another embodiment, the other end of the 2 nd breaking line 24 and the other end of the 3 rd breaking line 25 may be disposed between the pair of end edges 19b and 19c of the handle portion 19 in the left-right direction X. By disposing the other end of the 2 nd fracture line 24 and the other end of the 3 rd fracture line 25 between the pair of

end edges

19b, 19c, when the handle portion 19 is held and the packaged product 1 is lifted up, the force acting on the handle portion 19 is not easily transmitted to the other end of the 2 nd fracture line 24 and the other end of the 3 rd fracture line 25. It is therefore possible to prevent the package 3 from being unintentionally opened while carrying the packaged product 1.

As shown in fig. 1, the package 3 may be provided with an opening guide mark (mark) 28 indicating the position of the 1 st fracture line 23. The opening guide mark 28 is printed at a position closer to the bottom surface portion 15 than the 1 st fracture line 23, for example, at a position above the left side surface portion 13, and is designed to remind the 1 st fracture line 23 to open the package 3. The opening guide mark 28 may be a language design including characters, or may be a non-language design such as an arrow or a finger mark. As described above, since the non-fusion-bonded region 20 of the 1 st top surface portion 41 is folded inward in the left-right direction X, when the opening guide mark 28 is formed above (on the fusion-bonded region 18 side) the 1 st fracture line 23, there is a risk that the opening guide mark 28 is blocked by the 2 nd top surface portion 42 and the 3 rd top surface portion 43 and is difficult to see. In contrast, by forming the opening guide mark 28 on the bottom surface portion 15 side of the 1 st fracture line 23, the opening guide mark 28 is easily visible, and accordingly, the user can easily recognize the position of the 1 st fracture line 23.

Fig. 6 is a schematic view showing the fracture line 22 formed in the package 3. As shown in fig. 6, when the 1 st break line 23, the 2 nd break line 24, and the 3 rd break line 25 are easy-to-tear lines, the cutting ratio of the 1 st break line 23 may be set to be larger than the cutting ratio of the 2 nd break line 24 and the cutting ratio of the 3 rd break line 25. The cutting ratio indicates a ratio of the length of the cut portion 22c of the easy-tear line to the length of the non-cut portion 22 n. That is, the higher the cutting ratio, the longer the length of the cut portion 22c is relative to the length of the non-cut portion 22 n. The cut portion 22c is a portion of the easy-tear line provided with a notch, and the non-cut portion 22n is a portion of the easy-tear line not provided with a notch.

In the example shown in fig. 6, the length LC1 of the cut portion 22c of the 1 st fracture line 23 is the same as the length LC2 of the cut portion 22c of the 2 nd fracture line 24 and the length LC2 of the cut portion 22c of the 3 rd fracture line 25, whereas the length LN1 of the non-cut portion 22n of the 1 st fracture line 23 is formed shorter than the length LN2 of the non-cut portion 22n of the 2 nd fracture line 24 and the length LN2 of the non-cut portion 22n of the 3 rd fracture line 25. For example, the ratio of the length LC1 of the cut portion 22c of the 1 st fracture line 23 to the length LN1 of the non-cut portion 22n of the 1 st fracture line 23 is 3.

As described above, by making the cutting ratio of the 1 st fracture line 23 larger than the cutting ratio of the 2 nd fracture line 24 and the cutting ratio of the 3 rd fracture line 25, the 1 st fracture line 23 can be broken with a small force. Therefore, the package 3 can be easily opened with the 1 st breakage line 23 as a starting point. On the other hand, by making the cutting ratio of the 2 nd fracture line 24 and the cutting ratio of the 3 rd fracture line 25 smaller than the cutting ratio of the 1 st fracture line 23, a relatively large force is required to break the 2 nd fracture line 24 and the 3 rd fracture line 25, and therefore such a situation can be prevented: when the handle 19 is held and the packaged product 1 is lifted, the package 3 is unintentionally opened starting from the 2 nd or 3

rd breakage line

24 or 25.

Next, a method of manufacturing the packaged product 1 according to an embodiment will be described. Fig. 7 is a diagram schematically showing an example of a method of manufacturing the packaged product 1 according to the embodiment. Fig. 7 shows a method of manufacturing a packaged product having a package of the insert-flange type manufactured by welding upper and lower portions of a synthetic resin sheet in a cylindrical shape. The package 3 is not necessarily of a receptacle type, and may be of a rectangular package type (japanese: 12454124511245112465124831241248879\\\.

First, in order to manufacture the packaged product 1, the package 3 is formed to store the plurality of absorbent articles 2. First, as shown in fig. 7 (a), a cylindrical synthetic resin sheet member 50 is conveyed in the conveyance direction MD. Next, as shown in fig. 7 (b), both ends of the sheet member 50 in the cross direction CD are folded inward in the cross direction CD in a valley fold manner. By folding the sheet member 50 in this manner, the front surface 51, the back surface 52, the left surface 53, and the right surface 54 are formed on the sheet member 50. The left side surface 53 and the right side surface 54 are folded in a valley between the front surface 51 and the back surface 52. Therefore, the front surface 51 and the back surface 52 overlap each other in the thickness direction at the center portion of the sheet member 50 in the cross direction CD, the left side portion 53 folded in a valley fold overlaps the front surface 51 and the back surface 52 in the thickness direction at the left side portion of the sheet member 50, and the right side portion 54 folded in a valley fold overlaps the front surface 51 and the back surface 52 in the thickness direction at the right side portion of the sheet member 50.

Next, the break line 22 is formed in the top surface side portions of the front surface portion 51, the back surface portion 52, and the left side surface portion 53 of the sheet member 50. For example, the folded sheet member 50 is passed between a pair of rollers having cutting blades, thereby forming a tear line in the sheet member 50. At this time, the easy-tear line may be formed in the sheet member 50 by providing a notch from the inner surface side toward the outer surface side of the sheet member 50. By forming the cut in this manner, the package 3 is manufactured, and burrs due to the formation of the tear line are formed on the top surface portion 16 of the package 3. Since the burr protrudes from the inner surface side toward the outer surface side of the top surface portion 16, the position of the break line 22 can be recognized by the tactile sensation (feel) of the burr, and the break line 22 can be easily found.

As described above, the fracture line 22 extending in the cross direction CD is formed at the upper portion of the folded sheet member 50. The resulting fracture lines 22 include 1

st fracture line

23, 2

nd fracture line

24, and 3 rd fracture line 25. Thereafter, the bottom surface portion 15 is formed by sealing the bottom surface side portion of the formed sheet member 50 by thermal welding. Next, a plurality of absorbent articles 2 are loaded from the opening on the top surface side of the sheet member 50. For example, the plurality of absorbent articles 2 are stored in the sheet member 50 in a state where the absorbent articles 2 are folded in the transverse direction W toward the transverse direction CD of the sheet member 50 (i.e., the left-right direction X of the package 3).

Next, as shown in fig. 7 (c), the portion of the sheet member 50 on the upper surface side is sealed by thermal welding to form the top surface portion 16. At this time, the 1 st and 4 th

top surface portions

41 and 44 of the top surface portion 16 are fusion-bonded to the 2 nd and 3 rd

top surface portions

42 and 43 in a state of being folded in a valley toward the inside in the left-right direction X. In this case, the handle portion 19 may be formed by providing an inverted U-shaped cutout in the upper portion of the top surface portion 16.

The package 3 including the front portion 11, the back portion 12, the left side portion 13, the right side portion 14, the bottom portion 15, and the top portion 16 is thus formed. The front portion 11, the back portion 12, the left side portion 13, and the right side portion 14 correspond to regions between the bottom portion 15 and the top portion 16 among the front portion 51, the back portion 52, the left side portion 53, and the right side portion 54 of the sheet member 50. The packaged product 1 is manufactured as described above.

Next, a procedure of unsealing the packaged product 1 will be described with reference to fig. 8 to 10. Fig. 8 to 10 are perspective views showing an example of the opening step of the packaged product 1. When opening the packaged product 1, the user pinches the upper and lower portions of the 1 st fracture line 23 of the package 3 with fingers as shown in fig. 8, and tears the 1 st top surface portion 41 by tearing the 1 st fracture line 23 as shown in fig. 9. In this case, in package 3, the cutting ratio of 1 st breaking line 23 is set to be greater than the cutting ratio of 2 nd breaking line 24 and the cutting ratio of 3 rd breaking line 25. The 1 st fracture line 23 can be fractured with a relatively small force.

Next, when the user lifts the 1 st top surface portion 41 upward with the 1 st top surface portion 41 pinched by the fingers, the 2 nd fracture line 24 and the 3 rd fracture line 25 connected to the 1 st fracture line 23 are torn, and the 2 nd top surface portion 42 and the 3 rd top surface portion 43 are fractured. Then, as shown in fig. 10, when the 2 nd top surface portion 42 and the 3 rd top surface portion 43 are broken to the other end of the 2 nd fracture line 24 and the other end of the 3 rd fracture line 25 and a part of the top surface portion 16 is rolled up with a folding line 62 connecting the other end of the 2 nd fracture line 24 and the other end of the 3 rd fracture line 25 as a starting point, an opening portion 60 is formed in the top surface portion 16 of the package 3.

Then, the absorbent article 2 is taken out from the opening 60 formed in the top face portion 16. Here, the ratio of the length of the 2 nd fracture line 24 to the width of the front portion 11 in the left-right direction X is 60% to 90%, and the ratio of the length of the 3 rd fracture line 25 to the width of the back portion 12 in the left-right direction X is 60% to 90%, so that the opening width of the opening 60 in the left-right direction X may be smaller than the width of the absorbent article 2 accommodated in the package 3 in the lateral direction W. However, since the absorbent core 113 of the absorbent article 2 is provided with the plurality of stiffness reduced portions 131 to improve the bendability of the absorbent article 2 in the transverse direction W, the absorbent article 2 can be easily taken out from the opening 60 by bending the absorbent article 2 in the transverse direction W even when the opening width of the opening 60 is smaller than the width of the absorbent article 2.

Further, when the package 3 is opened, a part of the top surface portion 16 rolled up is returned to the original position to cover the opening 60, whereby the opening 60 can be closed. That is, a part of the rolled top surface portion 16 functions as a lid portion 64 for opening and closing the opening portion 60 of the package 3. By covering the opening 60 with the lid portion 64, it is possible to prevent foreign matter from entering the package 3 after opening. The absorbent article 2 can be stored sanitarily.

The step of opening the packaged product 1 is not limited to the example shown in fig. 8 to 10. For example, as shown in fig. 9, the package 3 may be pinched by fingers to tear the 1 st fracture line 23, and then the handle 19 may be held to lift the top surface portion 16, thereby breaking the top surface portion 16 along the 2 nd fracture line 24 and the 3 rd fracture line 25.

As described above, in the above embodiment, the package 3 has the fracture line 22 formed in the top surface portion 16. The expansion force of the plurality of absorbent articles 2 is less likely to act on the top surface portion 16 than on the front surface portion 11, the back surface portion 12, the left side surface portion 13, and the right side surface portion 14, and therefore slack is likely to occur in the top surface portion 16. In particular, since the non-welded region 20 of the 1 st top surface portion 41 is folded inward in the left-right direction X, tension is less likely to act thereon, and slack is likely to occur. Therefore, the user can easily grasp the 1 st top surface portion 41 in the vicinity of the 1 st fracture line 23, and can open the package 3 starting from the 1 st fracture line 23.

Further, the absorbent article 2 can be taken out from the opening 60 formed by opening the package 3 along the fracture line 22. At this time, in the package 3, the ratio of the length of at least one of the 2 nd breaking line 24 and the 3 rd breaking line 25 to the width of the front portion 11 in the left-right direction X is set to 60% or more and 90% or less, so the opening portion 60 having a relatively large width can be formed, and as a result, the absorbent article 2 can be easily taken out from the opened package 3.

Next, a packaged product of another embodiment will be explained. Fig. 11 is a perspective view showing another modification of the packaged product, and fig. 12 is a left side view of the packaged product shown in fig. 11. The package 3A of the packaged product 1A shown in fig. 11 and 12 differs from the package 3 of the packaged product 1 shown in fig. 1 in that: the break lines 22 are formed in the front surface portion 11, the back surface portion 12, and the left side surface portion 13. In the following description, points different from those of the above-described packaged product 1 will be mainly described, and redundant description will not be given.

As shown in fig. 11, in the package 3A in which the product 1A is packaged, the 1 st breaking line 23 of the breaking lines 22 is formed on the upper portion of the left side portion 13, the 2 nd breaking line 24 is formed on the upper portion of the front portion 11, and the 3 rd breaking line 25 is formed on the upper portion of the back portion 12. The 1 st fracture line 23 extends in the front-rear direction Y so as to cross the left side surface portion 13. The 2 nd break line 24 is connected to one end of the 1 st break line 23 and extends in the left-right direction X on the front portion 11. The 3 rd fracture line 25 is connected to the other end of the 1 st fracture line 23 and extends in the left-right direction X on the back surface portion 12.

As shown in fig. 12, the 1 st breaking line 23, the 2 nd breaking line 24, and the 3 rd breaking line 25 are formed on the left side surface portion 13, the front surface portion 11, and the back surface portion 12, respectively, at positions closer to the top surface portion 16 than the uppermost portions 2a of the plurality of absorbent articles 2 stored in the package 3A. The expansion force of the plurality of absorbent articles 2 is less likely to act on the portion of the package 3A closer to the top surface portion 16 than the uppermost portion 2a of the plurality of absorbent articles 2, and slack is more likely to occur. Therefore, in the package 3A, the user can easily open the package 3 by pinching the vicinity of the 1 st fracture line 23 formed in the left side surface portion 13 with the fingers and tearing the 1 st fracture line 23. By opening the package 3A along the 1 st breaking line 23, the 2 nd breaking line 24, and the 3 rd breaking line 25, a part of the package 3A can be used as a lid portion. The absorbent article 2 can be stored sanitarily.

While the package and the packaged product according to the various embodiments have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. That is, it should be noted that the above-mentioned embodiments are for illustrative purposes and do not limit the scope of the present invention.

For example, although the plurality of absorbent articles 2 are stored in the package 3 in a state where the plurality of absorbent articles 2 are folded in the lateral direction W of the package 3 in fig. 2, the direction of storing the plurality of absorbent articles 2 is not limited to the direction shown in fig. 2. For example, the plurality of absorbent articles 2 may be stored in the package 3 in a state in which the transverse direction W is folded in the front-rear direction Y of the package 3. Further, a plurality of absorbent articles 2 may be stored in the package 3 in a stacked state in the vertical direction Z.

Further, another breaking line may be formed in package 3 so as not to be continuous with breaking line 22. For example, the 4 th top surface portion 44 may be formed with a fracture line extending in the front-rear direction and not connected to any of the 1 st fracture line 23, the 2 nd fracture line 24, and the 3 rd fracture line 25. In the above embodiment, the 1 st fracture line 23 is formed on the 1 st top surface portion 41, but in one embodiment, the 1 st fracture line 23 may be formed on the 4 th top surface portion 44, the 2 nd fracture line 24 may extend in the left-right direction X from one end of the 1 st fracture line 23 formed on the 4 th top surface portion 44, and the 3 rd fracture line 25 may extend in the left-right direction X from the other end of the 1 st fracture line 23 formed on the 4 th top surface portion 44.

The various embodiments described above can be combined within a range that is not contradictory.
