Description

The present disclosure relates to packages for absorbent articles.

Generally, absorbent articles such as disposable diapers are distributed and sold in a packaged state. This type of package may have a break line such as a perforation that serves as a starting point for opening the package. For example, Patent Document 1 describes a substantially rectangular parallelepiped package that is made of synthetic resin such as polyester and that packages a plurality of diapers. A cut portion including perforations extending linearly in the vertical direction is formed on the front surface of the package. By opening the package along this cut section, the diaper housed within the package is taken out.

In the package described in Patent Document 1, since an elongated opening extending in the vertical direction is formed when the package is opened, it is difficult for the user to visually check the inside and take out the diaper. A package described in Patent Document 2, for example, is known as a package that makes diapers easy to take out. Patent Document 2 describes a paper package having a bottom, a top, and a peripheral surface, and this package accommodates a plurality of diapers stacked in at least two layers, one above the other. Perforations for opening the package are formed in the front part and the pair of side parts of the package, at locations corresponding to the boundaries between the upper and lower layers of the plurality of diapers.

In this package, by cutting the front part and the pair of side parts of the package along the perforations, the circumferential surface of the package can be divided into an upper part that accommodates the upper diaper and a lower part that accommodates the lower diaper. Separated. Then, by inverting the upper part of the package around the hinge part formed in the rear part, the plurality of diapers arranged in the upper row and the plurality of diapers arranged in the lower row are arranged in an external state. be exposed to. In this way, by opening the package so that the upper part and the lower part are separated, all the stored diapers are exposed, making it easy to take out multiple diapers at once, and making it easier to remove the diapers. It also becomes easy to grasp the number of remaining sheets.

Japanese Patent Application Publication No. 2020-196481 JP 2021-004051 Publication

In the package described in Patent Document 2, when the upper part of the package is grasped and the package is lifted, the load is concentrated on the perforation formed in the peripheral surface, and the package is lifted from the perforation as a starting point. The package may be opened unintentionally. In particular, when the package is used as a large-capacity package that accommodates a large number of absorbent articles, there is a risk that the upper portion and the lower portion may unintentionally separate.

Therefore, an object of the present disclosure is to provide a package from which an absorbent article can be easily taken out while suppressing unintended opening.

In one aspect, a synthetic resin package is provided that accommodates a plurality of absorbent articles, each having an absorbent core and stacked in at least two layers, one above the other. This package includes a bottom part, a top part, and a peripheral part disposed between the bottom part and the top part and including a front part, a back part, and a pair of side parts. A horizontal break line extending substantially parallel to the bottom surface portion is formed in the peripheral surface portion, and the horizontal break line extends continuously on at least three surfaces of the front surface portion, the back surface portion, and the pair of side surfaces. In the vertical direction, the absorbent cores of some absorbent articles arranged in the lower row among the plurality of absorbent articles and the absorbent cores of some absorbent articles arranged in the upper row among the plurality of absorbent articles and the absorbent core.

In the package according to the above aspect, since a break line is formed in the circumferential surface part and extends continuously on at least three surfaces of the front part, the back part, and the pair of side parts, the circumferential part is formed along the break line. By cutting open the package, the package is divided into an upper part that accommodates the upper absorbent article and a lower part that accommodates the lower absorbent article. Therefore, it becomes possible to easily take out the absorbent article from the package. Moreover, since the plurality of absorbent articles stacked in two layers, one above the other, tend to spread inside the package, a force (surface pressure) that forces the circumferential surface of the package to spread laterally acts. Particularly, at the position where the absorbent core having high rigidity is arranged, a large surface pressure acts on the peripheral surface of the package. Here, since the packaging body according to this aspect is made of a synthetic resin that has a lower bending resistance than paper, the portion of the packaging body on which surface pressure is applied deforms so as to swell outward, and tension ( tension) is increased. On the other hand, the absorbent cores of some absorbent articles arranged in the lower tier among the plurality of absorbent articles and the absorbent cores of some absorbent articles arranged in the upper tier among the plurality of absorbent articles In the intermediate position, the surface pressure acting on the absorbent core is reduced due to the absence of the absorbent core, so the tension on the circumferential surface portion at the position becomes relatively small. In the package according to this aspect, the absorbent core is not arranged in the vertical direction, and the horizontal break line is formed at a relatively low tension position, so when a load is applied to the package, the horizontal break line is difficult to cut open. Therefore, according to this package, it is possible to prevent the package from being opened unintentionally.

In one aspect, the horizontal break line may be formed continuously over the entire circumference of the peripheral surface portion. Since the horizontal break line is formed continuously over the entire circumference of the circumferential surface, when the package is cut open along the horizontal break line, the absorbent properties of the upper and lower tiers that accommodate the upper tier absorbent articles are reduced. The package is divided into a lower part that accommodates the goods. Due to the large size of a large-capacity package, it is sometimes difficult to secure storage space, but by dividing the package into an upper part and a lower part to reduce the size, the storage space can be used effectively. In addition, storing large-capacity packaging in a living space such as the living room where diapers are usually changed can be a nuisance, but by dividing the packaging into an upper part and a lower part, it becomes easier to store it in the living space. .

In one aspect, the horizontal break line may not be formed in the front part, but may be continuously formed in the back part and the pair of side parts. An image of a person is often printed on the front of the package. Therefore, if a break line is formed on the front surface, the image of the person will be cut off when the package is opened, which may cause psychological resistance to the user. In this aspect, the cutting line is not formed on the front part, but is continuously formed on the back part and a pair of side parts, thereby preventing psychological resistance from being given to the user when opening the package. be able to.

In one aspect, the peripheral surface part includes a lower part surrounding the absorbent cores of some absorbent articles arranged in the lower tier, and an upper part surrounding the absorbent cores of some absorbent articles arranged in the upper tier. The lower part and the upper part are areas that receive a surface pressure of 12N or more from a plurality of absorbent articles, and the middle part is a region that receives a surface pressure of less than 12N from a plurality of absorbent articles. The horizontal break line, which is a region subjected to surface pressure, may be formed in the middle part. By forming the horizontal break line in the middle portion where a small surface pressure acts, it is possible to prevent the package from being unintentionally opened.

In one aspect, the horizontal break line is formed along a boundary between some absorbent articles arranged in the lower tier and some absorbent articles arranged in the upper tier in the up-down direction. Good too. At a position corresponding to the boundary between some absorbent articles placed on the lower tier and some absorbent articles placed on the upper tier, tension is less likely to be applied to the peripheral surface of the package and loosening is likely to occur. By forming a horizontal break line in the package along the horizontal break line, the package becomes difficult to be opened unintentionally.

In one aspect, the peripheral surface portion may have a thickness of 40 μm or more and 80 μm or less. By setting the thickness of the peripheral surface to 40 μm, the strength of the package can be ensured. Furthermore, by setting the thickness of the peripheral surface to 80 μm or less, the package is flexibly deformed and the load is less likely to be concentrated on the horizontal break line formed on the peripheral surface.

In one embodiment, the peripheral surface portion may have a bending resistance of 100 mm or less. Note that the peripheral surface portion may have a bending resistance of 40 mm or more and 70 mm. By setting the bending resistance of the peripheral surface to 100 mm or less, or 40 mm or more to 70 mm, when the top surface of the package is grasped and the package is lifted, the package deforms flexibly and forms a shape on the peripheral surface. It becomes difficult for the load to concentrate on the horizontal break line.

In one embodiment, the total weight including the plurality of absorbent articles may be 800 g or more and 3500 g or less. By setting the total weight of the package containing a plurality of absorbent articles to 800 g or more and 3,500 g or less, the package is less likely to be unintentionally opened during transportation.

In one embodiment, the pair of side surfaces have raised portions in which two synthetic resin sheets are stacked and fused to each other, and the raised portions extend in the vertical direction between the bottom portion and the top portion. may be present. The upright part made of two overlapping synthetic resin sheets has higher rigidity than the part made of only one synthetic resin sheet, so by forming the upright part on the pair of side parts, The package is less likely to be crushed in the vertical direction. Therefore, the shape of the package can be easily maintained in an independent state, and the absorbent article can be easily taken out.

In one embodiment, an upper break line extending linearly in the vertical direction may further be formed at a position closer to the top surface than the horizontal break line of the peripheral surface. By opening the package along the upper break line, the absorbent article placed on the upper tier can be taken out from the package.

In one aspect, the horizontal break line includes a difficult-to-break part and an easy-to-break part that is more likely to break than the difficult-to-break part, and the peripheral surface includes an end of the easy-to-break part of the horizontal break line and an upper part of the break line. A connection breaking line may further be formed that extends in a curved shape between the end portion on the bottom side. In this aspect, since the easy-to-break part of the horizontal break line and the top break line are connected by the connection break line, the horizontal break line, the connection break line, and the top break line can be continuously cut.

In one aspect, the horizontal break line, the top break line, and the connection break line are perforations, and the length between the cuts in the difficult-to-break part of the horizontal break line may be shorter than the length between the cuts in the top break line. . By making the length between the cuts in the hard-to-break part shorter than the length between the cuts in the upper break line, the package can be easily opened along the horizontal break line.

In one embodiment, the length between the breaks in the easy-to-break portion of the horizontal break line and the break in the connection break line may be shorter than the length between the breaks in the difficult-to-break portion of the horizontal break line. In this embodiment, since the easy-to-break part of the horizontal break line and the connection break line are easy to break, by cutting the easy-to-break part of the horizontal break line while applying force to the top side, the upper part breaks through the connection break line. The wire can be cut continuously.

In one aspect, a lower break line extending linearly in the vertical direction may further be formed at a position closer to the bottom surface than the horizontal break line of the peripheral surface part. By opening the package along the lower tear line, the absorbent article placed on the lower tier can be easily taken out.

In one embodiment, the fiber direction of the peripheral surface portion may be oriented in the vertical direction. When the fiber direction of the peripheral surface portion is oriented in the vertical direction, the package becomes easy to tear in the vertical direction and difficult to tear in the width direction. That is, since the peripheral surface portion becomes difficult to break along the horizontal break line, it is possible to prevent the package from being unintentionally opened.

In one aspect, a first decorative element and a second decorative element are printed on the front part, the first decorative element is arranged at a position closer to the top part than the horizontal break line of the front part, and the second decorative element is , it may be arranged at a position closer to the bottom surface than the horizontal break line of the front surface. Note that the first decorative element may be a brand logo, and the second decorative element may be an illustration of a character. By printing the first decorative element and the second decorative element at positions closer to the top side than the horizontal break line of the front part and closer to the bottom side of the horizontal break line of the front part, When the package is divided, the product can be identified from the decorative elements printed on the upper and lower parts of the divided package.

In one aspect, an opening guide mark indicating the position of the horizontal break line and the opening direction is printed on the back part, and the opening guide mark does not need to be printed on the front part. According to this aspect, the user can be made aware of the position of the horizontal break line and the opening direction without spoiling the aesthetic appearance.

In one aspect, a third decorative element and a fourth decorative element are printed on at least one side surface of the pair of side surfaces, and the third decorative element is located closer to the top surface than the horizontal break line of the one side surface. The fourth decorative element is placed at a position closer to the bottom part than the horizontal break line of one side part, and the third decorative element is drawn upside down with respect to the fourth decorative element. Good too. By printing the third decorative element upside down, both the third decorative element and the fourth decorative element can be oriented upward when the package is stored divided into upper and lower parts. Note that the top surface portion does not need to have an opening that serves as a handle for the package.

In one embodiment, a synthetic resin package is provided that accommodates a plurality of absorbent articles stacked in at least two layers, one above the other. This package includes a bottom part, a top part, and a peripheral part disposed between the bottom part and the top part and including a front part, a back part, and a pair of side parts. The peripheral surface part includes a lower part that surrounds some of the absorbent articles arranged in the lower tier among the plurality of absorbent articles, and an upper part that surrounds some of the absorbent articles arranged in the upper tier among the plurality of absorbent articles. and an intermediate part located between the lower part and the upper part, and the intermediate part of the peripheral part has a horizontal breaking line that extends continuously on at least three of the front part, the back part, and the pair of side parts. It is formed.

In the package according to the above aspect, since the horizontal break line that extends continuously on at least three surfaces of the front part, the back part, and the pair of side parts is formed on the peripheral surface part, the horizontal break line is formed along the horizontal break line. By cutting open the peripheral surface, the package can be divided into an upper part that accommodates the upper absorbent article and a lower part that accommodates the lower absorbent article. Therefore, it becomes possible to easily take out the absorbent article from the package. In addition, multiple absorbent articles stacked in two tiers tend to spread inside the package, but since the horizontal break line is formed in the middle where tension is less likely to be applied, the load is applied to the package. When the horizontal break line is cut open, it is difficult to cut through the horizontal break line. Therefore, according to this package, it is possible to prevent the package from being opened unintentionally.

In one embodiment, the lower part and the upper part may be regions that receive a surface pressure of 12N or more from a plurality of absorbent articles, and the middle region may be a region that receives a surface pressure of less than 12N from a plurality of absorbent articles. Since the intermediate portion receives less surface pressure from the plurality of absorbent articles, by forming a horizontal break line in the intermediate portion, it is possible to prevent the package from being unintentionally opened. Note that the horizontal breaking line may be formed continuously over the entire circumference of the peripheral surface portion.

According to various aspects of the present invention, a package is provided that allows absorbent articles to be easily taken out while suppressing unintended opening.

Embodiments of the present disclosure will be described below with reference to the drawings. In the following description, the same or equivalent elements are given the same reference numerals, and overlapping descriptions will not be repeated. Parts of the drawings may be simplified or exaggerated for ease of understanding, and the dimensional ratios are not limited to those shown in the drawings.

Hereinafter, a package according to one embodiment will be described. FIG. 1 is a perspective view of a package 1 according to one embodiment. 2 is a front view of the package 1, and FIG. 3 is a rear view of the package 1. 4 is a left side view of the package 1, and FIG. 5 is a right side view of the package 1. For convenience of explanation, the drawings show a width direction X, a depth direction Y, and a vertical direction Z that are orthogonal to each other. The width direction be. The vertical direction Z is a direction perpendicular to the width direction X and the depth direction Y, and is a direction that intersects or perpendicularly intersects the bottom surface part 15 and the top surface part 16.

The package 1 accommodates a plurality of absorbent articles 2. As shown in FIGS. 1 to 5, the package 1 has a substantially rectangular parallelepiped shape, and includes a front part 11, a back part 12, a left part (side part) 13, a right part (side part) 14, a bottom part 15, and A top section 16 is provided. The front part 11 , the back part 12 , the left part 13 , and the right part 14 constitute a peripheral part 10 arranged between the bottom part 15 and the top part 16 . The absorbent article 2 housed in the package 1 is an article 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 sheets. Examples of the diaper include pants-type or tape-type disposable diapers.

FIG. 6 is a plan view showing a tape-type disposable diaper that is an example of the absorbent article 2. As shown in FIG. In FIG. 6, the absorbent article 2 is shown stretched to the point where no wrinkles are formed. The absorbent article 2 shown in FIG. 6 is a disposable diaper for children. Note that the absorbent article 2 may be a disposable diaper for adults or a disposable diaper for pets. As shown in FIG. 6, the absorbent article 2 extends in a vertical direction L connecting the wearer's ventral side to the dorsal side when worn, and in a horizontal direction W perpendicular to the vertical direction L. .

As shown in FIG. 6, the absorbent article 2 includes a main body portion 100, a pair of fastening tabs 120, and a target tape portion 130. The main body 100 is for absorbing excrement, and includes a top sheet 110, a back sheet 112, and an absorbent core 113. The top sheet 110 is placed on the front side of the absorbent article 2 and constitutes a surface that comes into contact with the wearer's skin. The topsheet 110 includes a center sheet 110a located at the center in the lateral direction W, and side sheets 110b covering both sides of the center sheet 110a in the lateral direction W.

A pair of elastic members 115 and 116 extending in the longitudinal direction L are provided on the side sheet 110b. The pair of elastic members 115 are disposed on both sides of the main body portion 100 in the horizontal direction W in a state of being stretched in the vertical direction L. By contracting the pair of elastic members 115 in the longitudinal direction L, the side edges of the main body portion 100 in the lateral direction W come into close contact with the wearer's legs, improving the fit of the absorbent article 2. The pair of elastic members 116 are provided inside the pair of elastic members 115 in the lateral direction W. The pair of elastic members 116 are connected to the side sheet 110b of the main body portion 100 in a stretched 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, so that a portion of the side sheet 110b stands up toward the wearer, forming a pair of leak-proof cuffs.

The pair of fastening tabs 120 are arranged near the ventral edge of the main body portion 100 in the longitudinal direction L, and extend outward in the lateral direction W. Each of the pair of fastening tabs 120 includes a joining section 122 made of a mechanical fastener or the like, and the joining section 122 is configured to be able to be joined to the target tape section 130. The target tape section 130 is arranged on the back surface side of the main body section 100 near the back edge of the main body section 100 in the longitudinal direction L. By connecting the pair of fastening tabs 120 to the target tape section 130, the absorbent article 2 is attached to the wearer.

Absorbent core 113 is arranged between topsheet 110 and backsheet 112. The absorbent core 113 includes, for example, ground pulp and polymeric absorbent (SAP) to absorb the wearer's urine. Note that the surface of the absorbent core 113 may be covered with a core wrap. The absorbent core 113 is disposed at the center of the main body portion 100 in the lateral direction W. The absorbent core 113 has a vertically elongated shape with the longitudinal direction L as the longitudinal direction and the lateral direction W as the lateral direction.

As shown in FIGS. 2 to 5, a plurality of absorbent articles 2 are stored inside the package 1 in a folded state. For example, the absorbent article 2 is housed in the package 1 with the side sheet 110b folded back inward in the lateral direction W and then folded in half in the longitudinal direction L. The plurality of absorbent articles 2 folded in this manner are stacked in at least two layers, one above the other, inside the package 1. The absorbent article 2a arranged at the upper stage among the plurality of absorbent articles 2 is arranged on the absorbent article 2b arranged at the lower stage among the plurality of absorbent articles 2. The upper absorbent article 2a and the lower absorbent article 2b are stacked in the width direction X and stored in the package 1 in a compressed state.

As described above, the package 1 has a substantially rectangular parallelepiped shape and stores a plurality of absorbent articles 2 therein. For example, the package 1 is a large-capacity package that includes a plurality of absorbent articles 2 and has a total weight of 800 g or more and 3,500 g or less. The peripheral surface part 10, front part 11, and back part 12 of the package 1 are made of synthetic resin such as polyethylene, polypropylene, or polyethylene terephthalate, and have a thickness of, for example, 40 μm or more and 80 μm or less. The thickness of the package 1 is obtained, for example, by cutting out multiple sample sides from the package 1, measuring the thickness of the multiple sample pieces using an electron microscope photograph, and calculating the average value of the measured values. Ru.

In one embodiment, the package 1 may be made of a sheet material having a bending resistance of 100 mm or less as measured in accordance with JIS L1096:2010 method A (45° cantilever method). In addition, the bending resistance of the package 1 may be 40 mm or more and 70 mm or less. Due to stretching during manufacturing, the fiber direction of the peripheral surface portion 10 of the package 1 is oriented in the vertical direction Z.

Note that since the package 1 is made of a material that is easily deformed, if a plurality of absorbent articles 2 are stored inside the package 1, the package 1 has a rectangular parallelepiped shape to be exact. There are things I haven't done yet. For example, a force is applied from the plurality of absorbent articles 2 to the front part 11, the back part 12, the left part 13, and the right part 14 to spread them outward, so that a part or all of the surface of the package 1 becomes curved, Alternatively, it may have unevenness.

The front part 11 and the back part 12 of the package 1 face each other in the depth direction Y of the package 1, and the left part 13 and the right part 14 face each other in the width direction X of the package 1. The bottom part 15 is connected to the lower ends of the front part 11, the back part 12, the left part 13, and the right part 14, and closes the bottom of the package 1. The top surface section 16 is connected to the upper ends of the front surface section 11, the back surface section 12, the left surface section 13, and the right surface section 14, and closes the top of the package 1.

As shown in FIG. 2, the peripheral surface portion 10 of the package 1 includes an upper portion 3, a lower portion 4, and an intermediate portion 5. The upper part 3 is a part that surrounds the absorbent core 113 of the absorbent article 2a placed in the upper tier from the side, and the lower part 4 is a part that surrounds the absorbent core 113 of the absorbent article 2b placed in the lower tier from the side. It is the enclosing part. The intermediate part 5 is located between the upper part 3 and the lower part 4. Since a plurality of absorbent articles 2 are stored in a compressed state inside the package 1, the plurality of absorbent articles 2 stacked in two layers, one above the other, are arranged in the width direction X inside the package 1. attempts to spread. Therefore, a force (surface pressure) that spreads the package 1 in the X direction acts on the peripheral surface 10 of the package 1. Particularly, a large surface pressure acts on the upper part 3 and lower part 4 of the package 1 that house the absorbent core 113 having high rigidity from the inside to the outside of the package 1. For example, a surface pressure of 12 N or more is applied to the upper part 3 and lower part 4 of the package 1 from the plurality of absorbent articles 2 . On the other hand, surface pressure is less likely to act on the intermediate portions 5 of the plurality of absorbent articles 2 where the absorbent cores 113 are not arranged. For example, the surface pressure that the intermediate portion 5 receives from the plurality of absorbent articles 2 is less than 12N.

Note that the surface pressure is the pressure per unit area that the peripheral surface portion 10 receives from the plurality of absorbent articles 2, and is measured using, for example, a digital force gauge. As a digital force gauge used to measure surface pressure, for example, SHIMPO FGP-0.2 manufactured by Nidec-Shimpo Corporation is used. This digital force gauge has a cylindrical detection section with a diameter of 10 mm. When measuring the surface pressure of the peripheral surface part 10 using this digital force gauge, the detection part of the digital force gauge is brought into contact with the peripheral surface part 10 of the package 1 containing a plurality of absorbent articles 2. The detection part is pressed 10 mm against the peripheral surface 10 of the package 1 at a speed of 300 mm/min. Then, the maximum value of the measured values measured by the digital force gauge at that time is acquired as the surface pressure that the peripheral surface portion 10 receives.

As mentioned above, a large surface pressure acts on the upper part 3 and lower part 4 of the package 1, so the upper part 3 and lower part 4 deform to bulge outward, and the tension of the upper part 3 and lower part 4 increases. is enhanced. On the other hand, since the surface pressure acting on the middle part 5 of the package 1 is relatively small, tension is not easily applied to the middle part 5. Due to this difference in tension, slack occurs in the intermediate portion 5.

As shown in FIGS. 1 to 5, the peripheral surface 10 of the package 1 is formed with a horizontal break line 22 extending substantially parallel to the bottom surface 15. As shown in FIGS. The horizontal break line 22 is a part of the peripheral surface part 10 that is more likely to break than other parts, and serves as a starting point for opening the package 1. The horizontal break line 22 is formed in the intermediate portion 5 of the peripheral surface portion 10. In other words, the horizontal break line 22 is formed in the vertical direction Z at a position between the absorbent core 113 of the upper absorbent article 2a and the absorbent core 113 of the lower absorbent article 2b. Details of the horizontal break line 22 will be described later.

FIG. 7 is a developed view of the package 1 cut along the boundary line 34 between the back surface section 12 and the right side section 14. As shown in FIG. 7, each of the front part 11, back part 12, left part 13, right part 14, bottom part 15, and top part 16 of the package 1 has a rectangular shape.

As shown in FIG. 7, the bottom part 15 is connected to the lower ends of the front part 11, the back part 12, the left part 13, and the right part 14. The lower part of the bottom part 15 is fused and connected at the fused part M1. The fused portion M1 is a region extending in a direction parallel to the boundary line between the peripheral surface portion 10 and the bottom surface portion 15.

The top surface section 16 is connected to the upper ends of the front surface section 11 , the back surface section 12 , the left surface section 13 , and the right surface section 14 . The upper part of the top surface part 16 is fused and coupled along the fused parts M2 and fused parts M3. The fused portion M2 and the fused portion M3 extend in the width direction X when viewed from the depth direction Y, and the fused portion M3 is formed closer to the bottom portion 15 than the fused portion M2.

A handle portion 19 that serves as a handle for the package 1 is formed at a position between the fused portion M2 and the fused portion M3 of the top surface portion 16. The handle portion 19 is an edge portion of a substantially elliptical opening formed by cutting out a portion of the top surface portion 16. By inserting a hand into the opening formed in the top surface part 16 and grasping the handle part 19, it is possible to lift and transport the package 1.

A horizontal break line 22 is formed on the peripheral surface 10 of the package 1 . The horizontal breaking line 22 extends continuously on four sides: the front part 11 , the back part 12 , the left part 13 , and the right part 14 . The horizontal break line 22 includes a first break line 23 , a second break line 24 , a third break line 25 , and a fourth break line 26 . The first break line 23 , the second break line 24 , the third break line 25 , and the fourth break line 26 are perforations including, for example, a cut part and a non-cut part, and are substantially parallel to the bottom part 15. It extends to

The first breaking line 23 is formed on the front part 11 and extends in the width direction X. More specifically, the first breaking line 23 crosses the front surface 11 between the boundary line 31 between the front surface section 11 and the left surface section 13 and the boundary line 32 between the front surface section 11 and the right surface section 14. It extends linearly in the width direction X. The second breaking line 24 is formed on the left surface portion 13 and extends in the depth direction Y. The second breaking line 24 is a straight line in the depth direction Y so as to cross the left surface section 13 between the boundary line 31 between the front surface section 11 and the left surface section 13 and the boundary line 33 between the rear surface section 12 and the left surface section 13. It has been extended for a long time. One end of the second break line 24 is connected to one end of the first break line 23 on the boundary line 31.

The third breaking line 25 is formed on the back surface portion 12 and extends in the width direction X. The third breaking line 25 is a straight line in the width direction It has been extended for a long time. One end of the third break line 25 is connected to the other end of the second break line 24 on the boundary line 33. The fourth breaking line 26 is formed on the right side portion 14 and extends in the depth direction Y. The fourth breaking line 26 is a straight line in the depth direction Y so as to cross the right side part 14 between the boundary line 32 between the front part 11 and the right side part 14 and the boundary line 34 between the back part 12 and the right side part 14. It has been extended for a long time. One end of the fourth break line 26 is connected to the other end of the first break line 23 on the boundary line 32, and the other end of the fourth break line 26 is connected to the other end of the third break line 25 on the boundary line 34. It is connected. That is, the horizontal breaking line 22 is continuously formed over the entire circumference of the peripheral surface portion 10.

Further, the horizontal break line 22 is formed in the intermediate portion 5 of the peripheral surface portion 10. In other words, the horizontal break line 22 is a line between the absorbent cores 113 of the plurality of absorbent articles 2a arranged in the upper tier and the absorbent cores 113 of the plurality of absorbent articles 2b arranged in the lower tier in the vertical direction Z. It is formed in a position between. As shown in FIGS. 2 to 5, the horizontal breaking line 22 is the boundary between the plurality of absorbent articles 2a arranged in the upper tier and the plurality of absorbent articles 2b arranged in the lower tier in the vertical direction Z. It may be formed along. As described above, since the surface pressure from the plurality of absorbent articles 2 is difficult to act on the middle part 5 of the package 1, the tension in the middle part 5 is small, and the middle part 5 is likely to slacken. By forming the horizontal break line 22 in the intermediate portion 5, the horizontal break line 22 becomes difficult to be cut open when the package 1 is carried by gripping the handle portion 19. Therefore, it is possible to prevent the package 1 from being opened unintentionally starting from the horizontal break line 22.

In one embodiment, horizontal break line 22 may have different strengths depending on location. For example, as shown in FIG. 7, the horizontal break line 22 may include an easy-to-break part 28 with relatively low strength and a difficult-to-break part 29 with relatively high strength. When the horizontal breaking line 22 is a perforation, the length between the cuts in the easy-to-break part 28 (the length of the uncut part) is formed shorter than the length between the cuts in the difficult-to-break part 29 . Thereby, the strength of the easily breakable portion 28 is weakened. As shown in FIG. 7 , the horizontal breaking line 22 includes a plurality of difficult-to-break parts 29 . The plurality of hard-to-break portions 29 are formed on the front surface portion 11 , the back surface portion 12 , the left surface portion 13 , and the right surface portion 14 of the peripheral surface portion 10 . The easily breakable portion 28 is arranged between the plurality of difficult to break portions 29 . In one embodiment, as shown in FIG. 7, the horizontal break line 22 includes two easily breakable parts 28, and one easily breakable part 28 is arranged to the left of the front part 11 so as to cross the boundary line 31. The other easily breakable portion 28 extends between the back surface portion 12 and the left surface portion 13 so as to cross the boundary line 33 .

Moreover, a plurality of upper break lines 40 and a plurality of connection break lines 42 may be formed on the circumferential surface portion 10 of the package 1 . The plurality of upper break lines 40 and the plurality of connection break lines 42 are, for example, perforations including a cut portion and a non-cut portion, and are formed closer to the top surface portion 16 than the horizontal break line 22 . The plurality of upper break lines 40 are break lines for taking out the upper absorbent article 2a from the package 1, and extend linearly in the vertical direction Z. As shown in FIG. 7, the package 1 has four upper break lines 40. Two of the four upper break lines 40 are formed on the front part 11 and the left face part 13, and extend parallel to each other across the boundary line 31. The other two upper fracture lines 40 among the plurality of upper fracture lines 40 are formed on the back surface portion 12 and the left surface portion 13, and extend parallel to each other across the boundary line 33.

One end of the plurality of connection break lines 42 is connected to the lower end of the plurality of upper break lines 40, and the other end of the plurality of connection break lines 42 is connected to both ends of the easily breakable portion 28 of the horizontal break line 22. There is. That is, the horizontal break line 22 is connected to the plurality of upper break lines 40 via the plurality of connection break lines 42 . Each of the plurality of connection breaking lines 42 extends in a curved shape that swells toward the difficult-to-break portion 29 of the adjacent horizontal breaking line 22 . As described above, the difficult-to-break portion 29 and the connection break line 42 of the horizontal break line 22 are formed to split into two from the end of the easy-to-break portion 28 . Further, the easy-to-break portion 28 of the horizontal break line 22, the upper break line 40, and the connection break line 42 cooperate to form a substantially U-shaped break line.

In one embodiment, horizontal break line 22, top break line 40, and connecting break line 42 may have different strengths. For example, when the horizontal break line 22, the top break line 40, and the connection break line 42 are perforations, the length between the breaks in the connection break line 42 is the length between the difficult-to-break part 29 of the horizontal break line 22 and the top break line The length is shorter than the length between the 40 cuts. As a result, the connection break line 42 is more easily broken than the difficult-to-break portion 29 of the horizontal break line 22 and the upper break line 40. Further, the length between the cuts in the upper break line 40 may be longer than the length between the cuts in the easily breakable part 28 and the difficult to break part 29 of the horizontal break line 22 . For example, the length ratio of the cut part and the uncut part of the easy-to-break part 28 is 2:3, and the length ratio of the cut part and the uncut part of the difficult-to-break part 29 is 2:4, The length ratio of the cut part and the uncut part of the upper break line 40 may be 2:5, and the length ratio of the cut part and the uncut part of the connection break line 42 may be 2:3. .

As described above, since the fiber direction of the circumferential surface portion 10 of the package 1 is oriented in the vertical direction Z, the circumferential surface portion 10 is less likely to be broken in the width direction X than in the vertical direction Z. On the other hand, in the package 1, the length between the cuts in the difficult-to-break part 29 of the horizontal break line 22 is made shorter than the length between the cuts in the upper break line 40, so that the package 1 is It becomes possible to easily open the package along the line 22. In addition, in the package 1, the length between the breaks in the easy-to-break portion 28 and the connection break line 42 is made shorter than the difficult-to-break portion 29 and the upper break line 40, so that the easy-to-break portion 28 and the connection break line 42 are The package 1 can be easily opened as a starting point.

In one embodiment, a plurality of lower break lines 50 may be further formed on the circumferential surface portion 10 of the package 1 . The plurality of lower break lines 50 are, for example, perforations including cut portions and non-cut portions, and are formed closer to the bottom portion 15 than the horizontal break line 22 . The plurality of lower break lines 50 are break lines for taking out the plurality of lower absorbent articles 2b, and extend linearly in the vertical direction Z below the plurality of upper break lines 40. The ends of the plurality of upper break lines 40 on the top surface portion 16 side may be connected to the horizontal break line 22 or may not be connected to the horizontal break line 22. When the lower break line 50 is a perforation, the length between the cuts of the lower break line 50 is longer than the horizontal break line 22 and the connection break line 42 . For example, the length ratio of the cut portion and the uncut portion of the lower break line 50 is 2:5.

The above-mentioned package 1 is manufactured by folding a planar synthetic resin sheet into a substantially rectangular parallelepiped shape and welding the folded sheet. For example, the package 1 includes a front section 11, a back section 12, a left section 13, a right section 14, a bottom section 15, and a top section 16 by folding two synthetic resin sheets. A substantially rectangular parallelepiped-shaped package 1 is manufactured by fusing two synthetic resin sheets at the bottom section 15 and top section 16. In the package 1 manufactured in this manner, upright portions 48 for raising the package 1 are formed on the left side 13 and the right side 14 (see FIGS. 4 and 5). The upright portion 48 is a portion in which two synthetic resin sheets are overlapped and fused to each other, and extends in the vertical direction Z between the bottom portion 15 and the top portion 16. The upright portion 48 has higher rigidity than other portions of the peripheral surface portion 10 (portions made of a single synthetic resin sheet). Therefore, by forming the standing portions 48 on the left side portion 13 and the right side portion 14, the package 1 becomes difficult to collapse in the vertical direction Z.

Next, the procedure for opening the package 1 will be explained. The package 1 provides multiple types of opening methods. First, a method of opening the package 1 along the horizontal break line 22 will be explained. When opening the package 1, the user first cuts the easy-to-break portion 28 by pinching the top and bottom of the horizontal break line 22 with fingers near the boundary line 31 or the boundary line 33 and pulling. At this time, in the package 1, since the length between the cuts in the easily breakable part 28 is formed to be short, the easily breakable part 28 can be cut with a small force. Next, the user cuts the easy-to-break part 28 in the width direction X and cuts the hard-to-break part 29 connected to the easy-to-break part 28 . Then, the horizontal breaking line 22 is broken along the entire circumference of the peripheral surface portion 10. As a result, the package 1 is divided into an upper part 3 and a lower part 4, as shown in FIG. Thereby, the plurality of absorbent articles 2a and 2b are exposed from the openings 52 and 54 formed in the upper part 3 and the lower part 4 in a state in which they are aligned in the width direction X.

Next, the user pinches the circumferential surface part 10 with his fingers and pulls it up toward the top surface part 16 to cut the connection breaking line 42. Then, as shown in FIG. 9, the user further pulls up the peripheral surface portion 10 toward the top surface portion 16 and cuts the upper break line 40. When the upper break line 40 is cut, an opening 56 is formed in the package 1 . The user can take out the upper absorbent article 2a housed in the package 1 through the opening 56 formed in this way.

Next, a method of opening the package 1 along the lower break line 50 will be explained. When opening the package 1 along the lower tear line 50, the user first pinches and pulls the upper and lower parts of the horizontal tear line 22 near the boundary line 31 or the boundary line 33 with his or her fingers to remove the easy-to-break part 28. disconnect. Next, the user pinches the circumferential surface part 10 with his or her fingers and pulls it down toward the bottom surface part 15 to cut the lower breaking line 50. As shown in FIG. 10, when the lower break line 50 is cut, an opening 58 is formed in the package 1. The user can take out the lower absorbent article 2b housed in the package 1 through the opening 58 formed in this way.
