Description

Technical Field

[0001] This disclosure relates to packaging for absorbent articles. Background Technology

[0002] Generally, absorbent articles such as disposable diapers are distributed and sold in a packaged state. Sometimes, a perforation line or other break line is formed in such a package, serving as the starting point for opening the package. For example, Patent Document 1 describes a roughly cuboid package made of synthetic resin such as polyester and containing multiple diapers. A cut portion containing a perforation line extending linearly in the vertical direction is formed on the front of the package. By opening the package along this cut portion, the diapers contained inside the package can be removed.

[0003] In the packaging described in Patent Document 1, because a long, narrow opening extending vertically is formed when the package is opened, it is difficult for the user to visually inspect the interior and remove the diapers. As a type of packaging that facilitates diaper removal, the packaging described in Patent Document 2 is known, for example. Patent Document 2 describes a paper packaging having a bottom, a top, and a perimeter, in which multiple diapers are housed in at least two layers stacked on top of each other. Perforations for opening the packaging are formed on the front surface and a pair of side surfaces at locations corresponding to the boundaries of the multiple diapers in the two layers.

[0004] In this packaging, the front surface and a pair of side surfaces are cut along the perforation line, separating the perimeter of the packaging into an upper portion for holding the upper diapers and a lower portion for holding the lower diapers. Then, by reversing the upper portion of the packaging around the hinge formed on the rear surface, the multiple diapers arranged in the upper and lower layers are exposed in a neatly arranged state. By opening the packaging in this way, separating the upper and lower portions, all the diapers are exposed, making it easy to remove multiple diapers at once and to easily determine the remaining number of diapers.

[0008] Patent Document 2: Japanese Patent Application Publication No. 2021-004051 Summary of the Invention

[0009] The problem that the invention aims to solve

[0010] In the packaging described in Patent Document 2, when the upper part of the packaging is held and the packaging is lifted, the load may sometimes be concentrated on the perforation line formed on the periphery, and the packaging may be accidentally opened starting from the perforation line. In particular, when the packaging is used as a large-capacity packaging for containing multiple absorbent articles, the upper part and the lower part may accidentally separate.

[0011] Therefore, the purpose of this disclosure is to provide a packaging that can prevent accidental opening and allow easy removal of absorbent articles.

[0012] Methods for solving problems

[0013] In one embodiment, a packaging body made of synthetic resin is provided, the packaging body containing a plurality of absorbent articles, each of the plurality of absorbent articles having an absorbent core and being stacked at least in upper and lower layers. The packaging body includes: a bottom surface; a top surface; and a peripheral surface, the peripheral surface being disposed between the bottom surface and the top surface, and including a front surface portion, a back surface portion, and a pair of side surfaces. A horizontal break line extending substantially parallel to the bottom surface is formed on the peripheral surface, the horizontal break line extending continuously with at least three of the front surface portion, the back surface portion, and the pair of side surfaces, and forming positions in the vertical direction between the absorbent cores of the lower layer of absorbent articles and the absorbent cores of the upper layer of absorbent articles.

[0014] In the packaging body described above, since a break line extending continuously from at least three of the front surface, back surface, and a pair of side surfaces is formed on the circumferential surface, the packaging body is divided into an upper part for housing the upper absorbent article and a lower part for housing the lower absorbent article by cutting along the break line on the circumferential surface. Therefore, the absorbent article can be easily removed from the packaging body. Furthermore, since multiple absorbent articles stacked in two layers intend to expand inside the packaging body, a force (surface pressure) of lateral expansion acts on the circumferential surface of the packaging body. In particular, at the location where an absorbent core with high rigidity is disposed, a greater surface pressure acts on the circumferential surface of the packaging body. Here, since the packaging body of this form is made of a synthetic resin with lower stiffness than paper, the portion of the packaging body subjected to surface pressure deforms by expanding outwards, increasing tension. On the other hand, in the position between the absorbent cores of the lower layer of absorbent articles and the absorbent cores of the upper layer of absorbent articles, the surface pressure acting is smaller than that corresponding to the absence of an absorbent core. Therefore, the tension on the periphery at this position becomes relatively small. In this type of packaging, since no absorbent core is arranged in the vertical direction, but a horizontal break line is formed at a position with relatively low tension, the horizontal break line is difficult to cut when a load is applied to the packaging. Therefore, according to this packaging, accidental opening of the packaging can be prevented.

[0015] In one configuration, the horizontal break line can be formed continuously along the entire circumference of the packaging surface. By forming the horizontal break line continuously along the entire circumference of the packaging surface, when the packaging is cut along this horizontal break line, it is divided into an upper part for containing the upper absorbent material and a lower part for containing the lower absorbent material. Since large-capacity packaging is often quite large, it can be difficult to secure storage space. However, by dividing the packaging into upper and lower parts and reducing its size, storage space can be utilized more effectively. Furthermore, storing large-capacity packaging in living spaces such as the living room where diapers are changed can sometimes be an obstacle, but by dividing the packaging into upper and lower parts, storage in living spaces becomes much easier.

[0016] In one embodiment, the horizontal break line is not formed on the front surface, but rather continuously on the back and a pair of side surfaces. Images of people are often printed on the front surface of the packaging. Therefore, if the break line is formed on the front surface, the image will be cut off when the packaging is opened, sometimes creating psychological resistance for the user. In this embodiment, because the break line is not formed on the front surface but continuously on the back and a pair of side surfaces, psychological resistance to the user is prevented when the packaging is opened.

[0017] In one embodiment, the peripheral surface may include: a lower portion surrounding absorbent cores of several absorbent articles disposed in a lower layer; an upper portion surrounding absorbent cores of several absorbent articles disposed in an upper layer; and a middle portion located between the lower and upper portions. The lower and upper portions are areas subjected to surface pressures of 12 N or more from the multiple absorbent articles, while the middle portion is an area subjected to surface pressures of less than 12 N from the multiple absorbent articles. A horizontal break line is formed in the middle portion. By forming a horizontal break line in the middle portion where less surface pressure is applied, accidental opening of the packaging can be prevented.

[0018] In one embodiment, the horizontal break line may be formed along the boundary between the absorbent articles disposed in the lower layer and the absorbent articles disposed in the upper layer in the vertical direction. At the position corresponding to the boundary between the absorbent articles in the lower layer and the absorbent articles in the upper layer, tension is difficult to apply to the periphery of the packaging, making it prone to relaxation. Therefore, by forming a horizontal break line along this boundary in the packaging, the packaging is made less likely to be accidentally opened.

[0019] In one embodiment, the peripheral surface may have a thickness of 40 μm or more but less than 80 μm. By making the thickness of the peripheral surface 40 μm, the strength of the packaging body can be ensured. In addition, by making the thickness of the peripheral surface less than 80 μm, the packaging body can deform flexibly, and the load is less likely to concentrate on the horizontal fracture line formed on the peripheral surface.

[0020] In one configuration, the peripheral surface may have a stiffness of 100 mm or less. Alternatively, the peripheral surface may have a stiffness of 40 mm or more but less than 70 mm. By setting the stiffness of the peripheral surface to 100 mm or less, or 40 mm or more but less than 70 mm, when the top surface of the packaging is held and the packaging is lifted, the packaging deforms softly, and the load is less likely to be concentrated on the horizontal fracture line formed on the peripheral surface.

[0021] In one embodiment, the total weight of the package containing multiple absorbent items is between 800g and 3500g. By ensuring that the total weight of the package containing multiple absorbent items is between 800g and 3500g, it is difficult to accidentally open the package during handling.

[0022] In one embodiment, a pair of side portions may have upright sections formed by fusing two overlapping synthetic resin sheets together, extending vertically between the bottom and top portions. Since the upright sections with two overlapping synthetic resin sheets have higher rigidity compared to portions consisting of only one synthetic resin sheet, forming these upright sections on the pair of side portions makes the packaging difficult to flatten vertically. Therefore, the shape of the packaging can be easily maintained in a self-standing state, and absorbent materials can be easily removed.

[0023] In one embodiment, an upper fracture line may also be formed on the side of the top surface closer to the horizontal fracture line of the periphery, and this upper fracture line extends in a straight line in the vertical direction. By opening the package along the upper fracture line, the absorbent item disposed on the upper layer can be removed from the package.

[0024] In one embodiment, the horizontal fracture line may include a difficult-to-fracture portion and an easily-fractured portion, the easily-fractured portion being more prone to fracture than the difficult-to-fractured portion. A connecting fracture line is also formed on the peripheral surface, extending in a curved shape between the end of the easily-fractured portion of the horizontal fracture line and the end of the upper fracture line on the bottom surface side. In this embodiment, because the easily-fractured portion of the horizontal fracture line is connected to the upper fracture line using the connecting fracture line, the horizontal fracture line, the connecting fracture line, and the upper fracture line can be continuously severed.

[0025] In one configuration, the horizontal break line, the upper break line, and the connecting break line can be perforation lines, with the length of the slits between the difficult-to-break sections of the horizontal break line being shorter than the length of the slits between the upper break line. By making the length of the slits between the difficult-to-break sections shorter than the length of the slits between the upper break line, the package can be easily opened along the horizontal break line.

[0026] In one embodiment, the length between the easily fractured portion of the horizontal fracture line and the slit between the connecting fracture lines may be shorter than the length between the slits of the difficult-to-fracture portion of the horizontal fracture line. In this embodiment, since the easily fractured portion of the horizontal fracture line and the connecting fracture line are easily fractured, the upper fracture line can be continuously cut through the connecting fracture line by applying force to the top surface while cutting the easily fractured portion of the horizontal fracture line.

[0027] In one embodiment, a lower fracture line may also be formed on the lower side of the horizontal fracture line compared to the periphery, and this lower fracture line extends in a straight line in the vertical direction. By opening the package along the lower fracture line, the absorbent material disposed in the lower layer can be easily removed.

[0028] In one configuration, the fibers of the periphery are oriented vertically. When the fibers of the periphery are oriented vertically, the packaging is easier to tear vertically but harder to tear along its width. That is, because the periphery is less likely to tear along a horizontal break line, accidental opening of the packaging can be prevented.

[0029] In one embodiment, a first decorative element and a second decorative element may be printed on the front surface. The first decorative element is positioned near the top of the horizontal break line on the front surface, and the second decorative element is positioned near the bottom of the horizontal break line on the front surface. Alternatively, 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 and second decorative elements at positions near the top and bottom of the horizontal break line on the front surface, respectively, when the packaging is divided along the horizontal break line, the product can be identified based on the decorative elements printed on the upper and lower parts of the divided packaging.

[0030] In one embodiment, an opening guide mark indicating the location of the horizontal break line and the opening direction is printed on the back, while no opening guide mark is printed on the front surface. According to this embodiment, the user can identify the location of the horizontal break line and the opening direction without compromising aesthetics.

[0031] In one embodiment, a third decorative element and a fourth decorative element may be printed on at least one of the two side surfaces. The third decorative element is positioned on the side of the other side surface near the top of the horizontal break line, and the fourth decorative element is positioned on the side of the other side surface near the bottom of the horizontal break line. The third decorative element is depicted upside down relative to the fourth decorative element. By printing the third decorative element upside down, both the third and fourth decorative elements can face upwards when the package is divided into upper and lower parts for storage. Alternatively, an opening for a handle as a package may not be formed on the top surface.

[0032] In one embodiment, a packaging body made of synthetic resin is provided, the packaging body containing a plurality of absorbent articles stacked in at least two layers. The packaging body includes: a bottom surface; a top surface; and a peripheral surface disposed between the bottom and top surfaces, the peripheral surface including a front surface, a back surface, and a pair of side surfaces. The peripheral surface includes: a lower portion surrounding a plurality of absorbent articles disposed in the lower layer; an upper portion surrounding a plurality of absorbent articles disposed in the upper layer; and a middle portion located between the lower and upper portions, a horizontal break line formed in the middle portion of the peripheral surface, the horizontal break line extending continuously with at least three of the front surface, back surface, and pair of side surfaces.

[0033] In the packaging described above, since a horizontal break line extending continuously from at least three of the front surface, back surface, and a pair of side surfaces is formed on the circumferential surface, the packaging can be divided into an upper part containing an upper layer of absorbent material and a lower part containing a lower layer of absorbent material by cutting along the horizontal break line. Therefore, the absorbent material can be easily removed from the packaging. Furthermore, although multiple absorbent materials stacked in two layers may expand inside the packaging, the horizontal break line is difficult to cut when a load is applied to the packaging because it is formed in the middle section where tension is difficult to apply. Therefore, according to this packaging, accidental opening of the packaging can be prevented.

[0034] In one configuration, the lower and upper portions may be areas subjected to surface pressures of 12 N or more from multiple absorbent materials, while the middle portion may be an area subjected to surface pressures of less than 12 N from multiple absorbent materials. Because the surface pressure from the multiple absorbent materials is lower in the middle portion, forming a horizontal break line in the middle portion can prevent accidental opening of the package. Alternatively, the horizontal break line may be formed continuously throughout the entire circumference of the package.

[0052] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. Furthermore, in the following description, the same or equivalent elements will be labeled with the same reference numerals, and descriptions will not be repeated. In the drawings, for ease of understanding, some parts may sometimes be simplified or exaggerated, and the scale is not limited to the scales shown in the drawings.

[0053] The following describes the packaging body according to one embodiment. Figure 1 This is a perspective view of packaging body 1 according to one embodiment. Figure 2 This is the front view of package 1. Figure 3 This is the rear view of package 1. Figure 4 This is the left side view of package 1. Figure 5 This is a right-side view of the packaging body 1. For ease of explanation, the width direction X, depth direction Y, and vertical direction Z, which are orthogonal to each other, are shown in the accompanying drawing. The width direction X is a direction that intersects or is orthogonal to the left surface portion 13 and the right surface portion 14 of the packaging body 1, which will be described later. The depth direction Y is a direction that intersects or is orthogonal to the front surface portion 11 and the back surface portion 12 of the packaging body 1. 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 is orthogonal to the bottom portion 15 and the top portion 16.

[0054] Packaging 1 contains multiple absorbent items 2. (e.g.) Figures 1-5 As shown, the packaging body 1 has a generally rectangular shape and includes a front surface 11, a back surface 12, a left surface (side surface) 13, a right surface (side surface) 14, a bottom surface 15, and a top surface 16. The front surface 11, back surface 12, left surface 13, and right surface 14 constitute a peripheral surface 10 disposed between the bottom surface 15 and the top surface 16. The absorbent article 2 contained in the packaging body 1 is an article that absorbs bodily fluids such as urine, blood, and sweat. Examples of absorbent articles 2 include diapers, toilet training pants, incontinence pads, sanitary napkins, and pet pads. Examples of diapers include disposable diapers in the form of underwear or straps.

[0055] Figure 6 This is a top view showing a strip-type disposable diaper as an example of absorbent article 2. Figure 6 The absorbent article 2 is shown in a stretched-out, wrinkle-free state. Figure 6 The absorbent item 2 shown is a disposable diaper for children. However, absorbent item 2 can also be a disposable diaper for adults or pets. Figure 6 As shown, the absorbent article 2 extends along a longitudinal direction L connecting the wearer's abdomen and back when worn, and a transverse direction W orthogonal to the longitudinal direction L.

[0056] like Figure 6 As shown, the absorbent article 2 includes a main body 100, a pair of hook and loop fasteners 120, and a target strap 130. The main body 100 is used to absorb excrement and includes a surface sheet 110, a back sheet 112, and an absorbent core 113. The surface sheet 110 is disposed on the surface side of the absorbent article 2, forming a surface that contacts the wearer's skin. The surface sheet 110 includes: a center sheet 110a, which is located at the center of the transverse direction W; and side sheets 110b, which cover the two sides of the transverse direction W of the center sheet 110a.

[0057] A pair of elastic members 115 and 116 are provided on the side panel 110b, extending longitudinally along the length L. The pair of elastic members 115, in their extended longitudinally along the length L, are positioned on both sides of the main body 100 in the transverse direction W. By contracting the pair of elastic members 115 in the longitudinally along the length L, the transverse side edges of the main body 100 are brought into close contact with the wearer's leg circumference, improving the fit of the absorbent article 2. A pair of elastic members 116 are positioned in the transverse direction W, further inward than the pair of elastic members 115. The pair of elastic members 116, in their extended longitudinally along the length L, are connected to the side panel 110b of the main body 100. By contracting the pair of elastic members 116 in the longitudinally along the length L when the absorbent article 2 is worn, a portion of the side panel 110b is raised towards the wearer, forming a pair of leak-proof folds.

[0058] A pair of hook and loop fasteners 120 are disposed near the ventral end edge of the longitudinal L of the main body 100 and extend outward in the transverse W direction. Each of the hook and loop fasteners 120 includes an engagement portion 122, which is configured to engage with a target strap portion 130, such as a mechanical fastener. The target strap portion 130 is disposed near the dorsal end edge of the longitudinal L of the main body 100 on the dorsal side of the main body 100. By connecting the pair of hook and loop fasteners 120 to the target strap portion 130, the absorbent article 2 is worn by the wearer.

[0059] An absorbent core 113 is disposed between the surface sheet 110 and the back sheet 112. The absorbent core 113 may contain, for example, pulverized pulp and a superabsorbent polymer (SAP), and absorbs the wearer's urine. Furthermore, the surface of the absorbent core 113 may be covered by a core-cladding layer. The absorbent core 113 is disposed at the center of the transverse direction W of the main body portion 100. The absorbent core 113 has an elongated shape with the longitudinal direction L as its long side and the transverse direction W as its short side.

[0060] like Figures 2-5 As shown, multiple absorbent items 2 are stored inside the packaging body 1 in a folded state. For example, after the side panel 110b is folded back inward to the transverse W, the absorbent items 2 are stored in the packaging body 1 in a folded state along the longitudinal L. The multiple absorbent items 2 folded in this way are stacked in at least two layers inside the packaging body 1. The absorbent item 2a disposed in the upper layer of the multiple absorbent items 2 is disposed on the absorbent item 2b disposed in the lower layer of the multiple absorbent items 2. The upper absorbent item 2a and the lower absorbent item 2b are stacked in the width direction X and stored in the packaging body 1 in a compressed state.

[0061] As described above, the packaging body 1 has a generally rectangular shape and houses multiple absorbent articles 2 inside. For example, the packaging body 1 is a large-capacity packaging body containing multiple absorbent articles 2 with a total weight of 800g or more and 3500g or less. The peripheral surface 10, front surface 11, and back surface 12 of the packaging body 1 are made of synthetic resins such as polyethylene, polypropylene, or polyethylene terephthalate, and have a thickness of, for example, 40μm or more and 80μm or less. Furthermore, regarding the thickness of the packaging body 1, for example, multiple sample edges are cut from the packaging body 1, the thickness of the multiple sample pieces is measured using electron microscopy, and the average value of the measured values ​​is calculated, thereby obtaining the thickness of the packaging body 1.

[0062] In one embodiment, the packaging body 1 may also be made of a sheet material having a stiffness of 100 mm or less in the measurement according to Method A (45° cantilever method) of JIS L1096:2010. Furthermore, the stiffness of the packaging body 1 may be 40 mm or more and 70 mm or less. By extending it during manufacturing, the fiber direction of the peripheral surface 10 of the packaging body 1 is oriented in the vertical direction Z.

[0063] Furthermore, since the packaging body 1 is made of a deformable material, when multiple absorbent items 2 are housed inside the packaging body 1, the packaging body 1 does not strictly have a cuboid shape. For example, outward expansion forces act from the multiple absorbent items 2 on the front surface 11, back surface 12, left surface 13, and right surface 14, and some or all of the surfaces of the packaging body 1 are sometimes curved or have irregularities.

[0064] The front surface portion 11 and the back surface portion 12 of the packaging body 1 face each other in the depth direction Y, and the left surface portion 13 and the right surface portion 14 face each other in the width direction X of the packaging body 1. The bottom surface portion 15 is connected to the lower ends of the front surface portion 11, the back surface portion 12, the left surface portion 13, and the right surface portion 14, closing the bottom of the packaging body 1. The top surface portion 16 is connected to the upper ends of the front surface portion 11, the back surface portion 12, the left surface portion 13, and the right surface portion 14, closing the upper part of the packaging body 1.

[0065] like Figure 2As shown, the peripheral surface 10 of the packaging body 1 includes an upper part 3, a lower part 4, and a middle part 5. The upper part 3 is the portion that surrounds the absorbent core 113 of the upper absorbent article 2a from the side, and the lower part 4 is the portion that surrounds the absorbent core 113 of the lower absorbent article 2b from the side. The middle part 5 is located between the upper part 3 and the lower part 4. Since multiple absorbent articles 2 are housed in a compressed state inside the packaging body 1, the multiple absorbent articles 2 stacked in upper and lower layers are intended to expand along the width direction X inside the packaging body 1. Therefore, the force (surface pressure) expanding along the X direction acts on the peripheral surface 10 of the packaging body 1. In particular, in the upper part 3 and lower part 4 of the packaging body 1, which house the absorbent core 113 with high rigidity, a large surface pressure acts from the inside of the packaging body 1 toward the outside. For example, a surface pressure of 12N or more acts from the multiple absorbent articles 2 on the upper part 3 and lower part 4 of the packaging body 1. On the other hand, surface pressure is difficult to exert on the middle portion 5 of the multiple absorbent articles 2 that is not equipped with absorbent core 113. For example, the surface pressure on the middle portion 5 from the multiple absorbent articles 2 is less than 12N.

[0066] Furthermore, surface pressure refers to the pressure per unit area exerted on the periphery 10 by the multiple absorbent articles 2, which is measured, for example, using a digital force gauge. As a digital force gauge used for measuring surface pressure, for example, the SHIMPO FGP-0.2 manufactured by Nidec Shinpo Co., Ltd. can be used. This digital force gauge has a cylindrical sensing section with a diameter of 10 mm. When measuring the surface pressure of the periphery 10 using this digital force gauge, the sensing section of the digital force gauge is brought into contact with the periphery 10 of the packaging body 1 containing the multiple absorbent articles 2, and the sensing section is pressed 10 mm onto the periphery 10 of the packaging body 1 at a speed of 300 mm / min. Then, the maximum value measured by the digital force gauge at this time is taken as the surface pressure exerted on the periphery 10.

[0067] As described above, due to the greater surface pressure acting on the upper part 3 and lower part 4 of the packaging body 1, the upper part 3 and lower part 4 deform in a way that expands outward, and the tension of the upper part 3 and lower part 4 increases. On the other hand, since the surface pressure acting on the middle part 5 of the packaging body 1 is relatively small, it is difficult to apply tension to the middle part 5. Due to this difference in tension, relaxation occurs in the middle part 5.

[0068] like Figures 1-5As shown, a horizontal break line 22 extending substantially parallel to the bottom surface 15 is formed on the peripheral surface 10 of the packaging body 1. The horizontal break line 22 is a part that is more prone to breakage compared to other parts of the peripheral surface 10, thus becoming the starting point for opening the packaging body 1. The horizontal break line 22 is formed in the middle portion 5 of the peripheral surface 10. In other words, the horizontal break line 22 is formed in the vertical direction Z 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.

[0069] Figure 7 This is an unfolded view of the packaging body 1 after it has been cut along the boundary line 34 between the back portion 12 and the right surface portion 14. (See diagram below.) Figure 7 As shown, the front surface 11, back surface 12, left surface 13, right surface 14, bottom surface 15 and top surface 16 of the packaging body 1 are all rectangular in shape.

[0070] like Figure 7 As shown, the bottom surface 15 is connected to the lower ends of the front surface 11, the back surface 12, the left surface 13, and the right surface 14. The lower part of the bottom surface 15 is fused together at the welded part M1. The welded part M1 is a region extending in a direction parallel to the boundary line of the peripheral surface 10 and the bottom surface 15.

[0071] The top surface 16 is connected to the upper ends of the front surface 11, the back surface 12, the left surface 13, and the right surface 14. The upper part of the top surface 16 is welded together along the welded portion M2 and the welded portion M3. When viewed from the depth direction Y, the welded portion M2 and the welded portion M3 extend along the width direction X, and the welded portion M3 is formed at a position closer to the bottom surface 15 than the welded portion M2.

[0072] A handle portion 19, which serves as a handle for the package body 1, is formed between the welded portions M2 and M3 of the top surface portion 16. The handle portion 19 is the edge portion of a generally elliptical opening formed by cutting off a portion of the top surface portion 16. By placing a hand into the opening formed in the top surface portion 16 and grasping the handle portion 19, the package body 1 can be lifted and transported.

[0073] A horizontal break line 22 is formed on the periphery 10 of the packaging body 1. The horizontal break line 22 extends continuously to the four surfaces: the front surface 11, the back surface 12, the left surface 13, and the right surface 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, for example, perforation lines including cut portions and non-cut portions, extending substantially parallel to the bottom surface 15.

[0074] A first fracture line 23 is formed on the front surface portion 11 and extends along the width direction X. More specifically, the first fracture line 23 extends linearly along the width direction X, traversing the front surface portion 11 between the boundary line 31 of the front surface portion 11 and the left surface portion 13 and the boundary line 32 of the front surface portion 11 and the right surface portion 14. A second fracture line 24 is formed on the left surface portion 13 and extends along the depth direction Y. The second fracture line 24 extends linearly along the depth direction Y, traversing the left surface portion 13 between the boundary line 31 of the front surface portion 11 and the left surface portion 13 and the boundary line 33 of the back surface portion 12 and the left surface portion 13. One end of the second fracture line 24 connects to one end of the first fracture line 23 on the boundary line 31.

[0075] A third fracture line 25 is formed on the back surface portion 12 and extends along the width direction X. The third fracture line 25 extends in a straight line along the width direction X, traversing the back surface portion 12 between the boundary line 33 of the back surface portion 12 and the left surface portion 13, and the boundary line 34 of the back surface portion 12 and the right surface portion 14. One end of the third fracture line 25 connects to the other end of the second fracture line 24 on the boundary line 33. A fourth fracture line 26 is formed on the right surface portion 14 and extends along the depth direction Y. The fourth fracture line 26 extends in a straight line along the depth direction Y, traversing the right surface portion 14 between the boundary line 32 of the front surface portion 11 and the right surface portion 14, and the boundary line 34 of the back surface portion 12 and the right surface portion 14. One end of the fourth fracture line 26 connects to the other end of the first fracture line 23 on the boundary line 32, and the other end of the fourth fracture line 26 connects to the other end of the third fracture line 25 on the boundary line 34. That is, the horizontal fracture line 22 is formed continuously around the entire perimeter of the surface 10.

[0076] Furthermore, a horizontal break line 22 is formed in the middle portion 5 of the peripheral surface 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 plurality of absorbent articles 2a disposed in the upper layer and the absorbent core 113 of the plurality of absorbent articles 2b disposed in the lower layer. Additionally, as... Figures 2-5 As shown, the horizontal break line 22 can also be formed in the vertical direction Z along the boundary between the multiple absorbent articles 2a disposed in the upper layer and the multiple absorbent articles 2b disposed in the lower layer. As described above, since the surface pressure from the multiple absorbent articles 2 is difficult to act on the middle portion 5 of the package 1, the tension in the middle portion 5 is small, and relaxation is easily generated in the middle portion 5. By forming the horizontal break line 22 in such a middle portion 5, the horizontal break line 22 is difficult to be cut when the handle portion 19 is gripped and the package 1 is carried. Therefore, it is possible to prevent the package 1 from being accidentally opened starting from the horizontal break line 22.

[0077] In one embodiment, the horizontal break line 22 may also have varying strengths depending on its location. For example, as... Figure 7As shown, the horizontal fracture line 22 may also include a relatively weak, easily fractured portion 28 and a relatively strong, difficult-to-fracture portion 29. When the horizontal fracture line 22 is a perforation line, the length of the slits (the length of the non-cut portion) in the easily fractured portion 28 is shorter than the length of the slits in the difficult-to-fracture portion 29. Therefore, the strength of the easily fractured portion 28 is weakened. Figure 7 As shown, the horizontal fracture line 22 includes a plurality of difficult-to-fracture portions 29. The plurality of difficult-to-fracture portions 29 are formed on the front surface portion 11, back surface portion 12, left surface portion 13, and right surface portion 14 of the peripheral surface portion 10. Easily fractured portions 28 are disposed between the plurality of difficult-to-fracture portions 29. In one embodiment, as... Figure 7 As shown, the horizontal fracture line 22 includes two fractured portions 28. One fractured portion 28 extends between the front surface portion 11 and the left surface portion 13 in a manner that crosses the boundary line 31, while the other fractured portion 28 extends between the back surface portion 12 and the left surface portion 13 in a manner that crosses the boundary line 33.

[0078] Alternatively, multiple upper fracture lines 40 and multiple connecting fracture lines 42 may be formed on the periphery 10 of the packaging body 1. The multiple upper fracture lines 40 and multiple connecting fracture lines 42 may be, for example, perforated lines including cut portions and non-cut portions, formed on the side closer to the top surface 16 than the horizontal fracture line 22. The multiple upper fracture lines 40 are fracture lines used for removing the upper absorbent article 2a from the packaging body 1, extending in a straight line in the vertical direction Z. Figure 7 As shown, the packaging body 1 has four upper break lines 40. Two of the four upper break lines 40 are formed on the front surface portion 11 and the left surface portion 13, and extend parallel to each other across the boundary line 31. The other two of the plurality of upper break 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.

[0079] One end of each of the multiple connecting fracture lines 42 is connected to the lower end of each of the multiple upper fracture lines 40, and the other end of each of the multiple connecting fracture lines 42 is connected to both ends of the easily fractured portion 28 of the horizontal fracture line 22. That is, the horizontal fracture line 22 is connected to the multiple upper fracture lines 40 via the multiple connecting fracture lines 42. The multiple connecting fracture lines 42 extend in a curved shape, expanding toward the difficult-to-fracture portion 29 of the adjacent horizontal fracture line 22. As described above, the difficult-to-fracture portion 29 of the horizontal fracture line 22 and the connecting fracture lines 42 are formed to split into two strands from the end of the easily fractured portion 28. In addition, the easily fractured portion 28 of the horizontal fracture line 22, the upper fracture line 40, and the connecting fracture lines 42 cooperate to form a roughly U-shaped fracture line.

[0080] In one embodiment, the horizontal fracture line 22, the upper fracture line 40, and the connecting fracture line 42 may have different strengths. For example, when the horizontal fracture line 22, the upper fracture line 40, and the connecting fracture line 42 are perforated lines, the length of the slits in the connecting fracture line 42 is made shorter than the length of the slits in the difficult-to-break portion 29 of the horizontal fracture line 22 and the upper fracture line 40. Therefore, the connecting fracture line 42 is easier to break than the difficult-to-break portion 29 of the horizontal fracture line 22 and the upper fracture line 40. Alternatively, the length of the slits in the upper fracture line 40 may be made longer than the length of the slits in the easily-breaking portion 28 and the difficult-to-break portion 29 of the horizontal fracture line 22. For example, the ratio of the length of the cut portion to the length of the non-cut portion of the easily fractured portion 28 can be 2:3, the ratio of the length of the cut portion to the length of the non-cut portion of the difficult-to-fracture portion 29 can be 2:4, the ratio of the length of the cut portion to the length of the non-cut portion of the upper fracture line 40 can be 2:5, and the ratio of the length of the cut portion to the length of the non-cut portion of the connecting fracture line 42 can be 2:3.

[0081] As described above, since the fibers of the peripheral surface 10 of the packaging body 1 are oriented in the vertical direction Z, the peripheral surface 10 is less prone to breakage in the width direction X compared to the vertical direction Z. Conversely, in the packaging body 1, since the length of the slit between the difficult-to-break portion 29 of the horizontal break line 22 is shorter than the length of the slit between the upper break line 40, the packaging body 1 can be easily opened along the horizontal break line 22. Furthermore, in the packaging body 1, since the length of the slit between the easily breakable portion 28 and the connecting break line 42 is shorter than the length of the difficult-to-break portion 29 and the upper break line 40, the packaging body 1 can be easily opened starting from the easily breakable portion 28 and the connecting break line 42.

[0082] In one embodiment, a plurality of lower break lines 50 may also be formed on the peripheral surface 10 of the packaging body 1. The plurality of lower break lines 50 may be, for example, perforated lines including cut portions and non-cut portions, formed on the side closer to the bottom surface 15 than the horizontal break line 22. The plurality of lower break lines 50 are break lines for removing the plurality of absorbent articles 2b from the lower layer, extending 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 16 side may or may not be connected to the horizontal break line 22. When the lower break line 50 is a perforated line, the length between the cuts of the lower break line 50 is formed to be longer than the horizontal break line 22 and the connecting break line 42. For example, the ratio of the length of the cut portion to the length of the non-cut portion of the lower break line 50 is 2:5.

[0083] The aforementioned packaging body 1 is manufactured by folding a planar synthetic resin sheet into a generally rectangular shape and then fusing it together. For example, packaging body 1 is manufactured by folding two synthetic resin sheets to form a front surface portion 11, a back surface portion 12, a left surface portion 13, a right surface portion 14, a bottom surface portion 15, and a top surface portion 16, and then fusing the two synthetic resin sheets together at the left surface portion 13, the right surface portion 14, the bottom surface portion 15, and the top surface portion 16, thereby manufacturing a generally rectangular packaging body 1. In this manufactured packaging body 1, upright portions 48 (see reference) are formed on the left surface portion 13 and the right surface portion 14 to make the packaging body 1 stand up. Figure 4 and Figure 5 The upright portion 48 is a portion formed by overlapping and fusing two synthetic resin sheets together, extending in the vertical direction Z between the bottom portion 15 and the top portion 16. The upright portion 48 has higher rigidity compared to other portions of the peripheral portion 10 (the portion consisting of a single synthetic resin sheet). Therefore, by forming the upright portion 48 on the left surface portion 13 and the right surface portion 14, the packaging body 1 is less likely to be flattened in the vertical direction Z.

[0084] Next, the steps for opening the packaging 1 will be explained. The packaging 1 offers several opening methods. First, the method of opening the packaging 1 along the horizontal break line 22 will be explained. When opening the packaging 1, the user first pinches the horizontal break line 22 near the boundary line 31 or 33 with their fingers and pulls, thereby cutting off the easily breakable portion 28. At this time, because the length of the cut between the easily breakable portions 28 in the packaging 1 is relatively short, the easily breakable portion 28 can be cut off with less force. Next, the user cuts the easily breakable portion 28 along the width direction X and cuts off the difficult-to-break portion 29 connected to the easily breakable portion 28. Then, the horizontal break line 22 is broken along the entire circumference of the perimeter 10. As a result, as... Figure 8 As shown, the packaging body 1 is divided into an upper part 3 and a lower part 4. As a result, multiple 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 neatly arranged state along the width direction X.

[0085] As described above, by exposing multiple absorbent items 2 in a neatly arranged state along the width direction X, it is easy to remove multiple absorbent items 2 from the packaging body 1, and the remaining number of absorbent items 2 can be clearly seen. Furthermore, since the packaging body 1, which holds a large number of absorbent items 2, is relatively large, it is sometimes difficult to ensure sufficient storage space. However, by dividing the packaging body 1 into an upper part 3 and a lower part 4, storage space can be effectively utilized. Additionally, dividing the packaging body 1 into an upper part 3 and a lower part 4 makes it easier to store the packaging body 1 in living spaces such as the living room where diapers are changed. Moreover, as... Figure 8As shown, when the packaging 1 is divided into an upper part 3 and a lower part 4, the upper part 3 and the lower part 4 are stored with the bottom part 15 and the top part 16 as their lower surfaces, respectively. At this time, since upright portions 48 are formed on the left surface portion 13 and the right surface portion 14, the upper part 3 and the lower part 4 are difficult to flatten in the vertical direction Z, and therefore, the upper part 3 and the lower part 4 can stand upright on their own. Therefore, the absorbent item 2 can be easily removed from the upper part 3 and the lower part 4.

[0086] Next, the method for opening the packaging 1 along the upper fracture line 40 will be described. In the packaging 1, even if the user does not prefer the packaging 1 to be divided into an upper part 3 and a lower part 4, it can still be opened along the upper fracture line 40. When opening the packaging 1 along the upper fracture line 40, firstly, the user pinches the horizontal fracture line 22 near the boundary line 31 or boundary line 33 with their fingers and pulls it, thereby cutting off the easily breakable part 28. Next, while pinching the peripheral part 10 with their fingers, the user pulls towards the top part 16 to cut off the connecting fracture line 42. Then, as... Figure 9 As shown, the user pulls the peripheral surface 10 further towards the top surface 16 to cut the upper fracture line 40. When the upper fracture line 40 is cut, an opening 56 is formed in the packaging body 1. The user can then remove the absorbent article 2a contained in the upper layer of the packaging body 1 from the opening 56 formed in this way.

[0087] Next, the method for opening the package 1 along the lower break line 50 will be described. When opening the package 1 along the lower break line 50, firstly, the user pinches the horizontal break line 22 near the boundary line 31 or 33 with their fingers and pulls it, thereby cutting off the easily breakable portion 28. Next, the user, while pinching the perimeter 10 with their fingers, pulls it downwards towards the bottom surface 15 to cut off the lower break line 50. (As...) Figure 10 As shown, when the lower break line 50 is cut, an opening 58 is formed in the packaging body 1. The user can remove the absorbent article 2b contained in the lower layer of the packaging body 1 from the opening 58 formed in this way.

[0088] As explained above, in the above embodiment, since a horizontal break line 22 extending continuously throughout the circumference of the periphery 10 is formed on the packaging body 1, the packaging body 1 can be divided into an upper part 3 and a lower part 4 by cutting the periphery 10 along the horizontal break line 22. Therefore, the absorbent articles 2 can be easily removed from the packaging body 1. In addition, in the packaging body 1, the horizontal break line 22 is formed in the middle part 5 where the surface pressure from the multiple absorbent articles 2 is relatively small. Therefore, even when the packaging body 1 is held and carried by the handle 19, the load is unlikely to be concentrated on the horizontal break line 22, and the horizontal break line 22 is difficult to cut. Therefore, according to this packaging body 1, it is possible to prevent the packaging body 1 from being accidentally opened.

[0089] In addition, Figure 1 In the package 1 shown, a horizontal break line 22 is formed around the entire circumference of the peripheral surface 10. However, in one embodiment, it may be formed only on three of the peripheral surface portions 11, 12, 13, and 14. For example, as... Figure 11 As shown, the horizontal break line 22 may also be formed only on the front surface portion 11, the back surface portion 12, and the left surface portion 13, and not on the right surface portion 14. In this embodiment, the packaging body 1 is separated into an upper portion 3 and a lower portion 4 by cutting along the horizontal break line 22 formed on the front surface portion 11, the back surface portion 12, and the left surface portion 13. Then, as... Figure 12 As shown, by reversing the upper part 3 around the bend 68 of the right surface part 14, multiple absorbent items 2 can be exposed in a neat arrangement along the width direction X. Therefore, multiple absorbent items 2 can be easily removed from the packaging body 1, and the remaining number of absorbent items 2 can be clearly seen at a glance.

[0090] Alternatively, the horizontal break line 22 may not be formed on the front surface 11, but rather continuously on the back surface 12, left surface 13, and right surface 14. Images of people are often printed on the front surface 11 of the packaging 1. If the horizontal break line 22 is formed on the front surface 11, the image of the person will be cut off when the packaging 1 is opened, which may sometimes create psychological resistance in the user. When the horizontal break line 22 is not formed on the front surface 11 but on the back surface 12, left surface 13, and right surface 14, the image of the person will not be cut off when the packaging 1 is opened, thus preventing psychological resistance in the user.

[0091] Next, refer to Figures 13-15 The packaging body of another embodiment will be described. Figure 13 This is a front view of package 1A according to another embodiment. Figure 14 This is the rear view of package 1A. Figure 15 This is a left-side view of package 1A. The following mainly focuses on... Figures 1-5 The differences of the package 1 shown are explained, and repeated explanations are omitted.

[0092] As described later, multiple decorative elements are printed on the packaging body 1A. "Decorative elements" refers to graphics, patterns, text, logos, illustrations, photographs, etc., printed on the packaging body 1A in a manner that allows for visual confirmation from the outside. In one embodiment, the multiple decorative elements are printed on the packaging body 1A using three or fewer hues. "Hue" refers to color tone. "Printed on the packaging body 1A using three or fewer hues" means, for example, printing using three or fewer hues from the ten hues represented by the Munsell color system.

[0093] like Figure 13 As shown, the upper part of the welded portion M3 of the top surface 16 of the packaging body 1A is cut off. Therefore, the difference between the top surface 16 of the packaging body 1A and the top surface 16 of the packaging body 1 is that the handle portion 19 (opening) that serves as the handle of the packaging body 1A is not formed.

[0094] A first decorative element 71 and a second decorative element 72 are printed on the front surface 11 of the packaging body 1A. Figure 13 In the example shown, the first decorative element 71 is a logo (brand mark) containing the brand name of the absorbent item 2, and the second decorative element 72 is an illustration of an animal character. Alternatively, the first decorative element 71 could also be an illustration or photograph of a toddler, a product, etc.

[0095] like Figure 13 As shown, the first decorative element 71 is printed on the upper part 3 of the front surface portion 11, and the second decorative element 72 is printed on the lower part 4 of the front surface portion 11. That is, the first decorative element 71 is positioned closer to the top part 16 than the horizontal break line 22 of the front surface portion 11, and the second decorative element 72 is positioned closer to the bottom part 15 than the horizontal break line 22 of the front surface portion 11. As described above, the first decorative element 71 and the second decorative element 72 are positioned in a position that does not cross the horizontal break line 22. Therefore, when the packaging body 1A is divided along the horizontal break line 22, the first decorative element 71 and the second decorative element 72 can be prevented from being cut off. In addition, by printing the first decorative element 71 and the second decorative element 72 on the upper part 3 and the lower part 4 of the front surface portion 11 respectively, even when the packaging body 1A is divided into the upper part 3 and the lower part 4 along the horizontal break line 22, the product can be identified based on the decorative elements printed on the upper part 3 and the lower part 4.

[0096] like Figure 14As shown, a plurality of first opening guide marks 73 are printed on the back 12 of the packaging body 1A, indicating the position of the horizontal break line 22 and the opening direction. The first opening guide marks 73 have the function of visually guiding the way of opening the packaging body 1A. For example, the first opening guide mark 73 has a triangular shape with its vertex pointing towards the width direction X, and is positioned at a position overlapping the horizontal break line 22. Furthermore, the shape of the first opening guide mark 73 is not limited to a triangular shape, as long as it allows the user to identify the position of the horizontal break line 22 and the opening direction; for example, it can also be an arrow shape.

[0097] like Figure 13 As shown, the first opening guide mark 73 is not printed on the front surface portion 11. By printing the first opening guide mark 73 only on the back portion 12, the user can identify the opening direction of the packaging 1A without compromising the aesthetics of the packaging 1A.

[0098] like Figure 15 As shown, a plurality of second opening guide marks 74 are printed on the left surface 13 of the packaging body 1A, indicating the position of the upper break line 40 and the opening direction. The second opening guide marks 74 have the function of visually guiding the way the packaging body 1A is opened. For example, the second opening guide mark 74 has a triangular shape with its vertex pointing in the vertical direction Z, and is printed in a position adjacent to the upper break line 40. In addition, the shape of the second opening guide mark 74 is not limited to a triangular shape, as long as it allows the user to identify the position of the upper break line 40 and the opening direction; for example, it can also be an arrow shape.

[0099] Additionally, a third decorative element 75 and a fourth decorative element 76 are printed on the left surface 13 of the packaging body 1A. The third decorative element 75 and the fourth decorative element 76 are, for example, illustrations of animal characters. Figure 15 As shown, it is also possible that a plurality of third decorative elements 75 and a plurality of fourth decorative elements 76 are printed on the left surface portion 13.

[0100] The third decorative element 75 is printed on the upper part 3 of the left surface portion 13, and the fourth decorative element 76 is printed on the lower part 4 of the left surface portion 13. That is, the third decorative element 75 is positioned closer to the top surface portion 16 than the horizontal break line 22 of the left surface portion 13, and the fourth decorative element 76 is positioned closer to the bottom surface portion 15 than the horizontal break line 22 of the left surface portion 13.

[0101] like Figure 15As shown, the third decorative element 75 is depicted upside down relative to the fourth decorative element 76. That is, the third decorative element 75 is printed with its orientation facing upwards when upside down, so that the top surface 16 of the packaging body 1A is the lower surface. On the other hand, the fourth decorative element 76 is printed with its orientation facing upwards when positioned so that the bottom surface 15 of the packaging body 1A is the lower surface. Figure 8 As shown, when the packaging body 1A is divided into an upper part 3 and a lower part 4, the upper part 3 of the packaging body 1A is stored with the top surface 16 becoming the lower surface. By printing the third decorative element 75 upside down, both the third decorative element 75 and the fourth decorative element 76 can face upwards when the packaging body 1A is divided and stored. Furthermore, the third decorative element 75 and the fourth decorative element 76 can be printed on both the left surface 13 and the right surface 14, or only on the right surface 14.

[0102] The packaging of various embodiments has been described above, but the present invention is not limited to the above embodiments, and various modifications can be made without changing the spirit of the invention. That is, it should be noted that the above embodiments are for illustrative purposes only and do not limit the scope of the present invention.

[0103] For example, in the above embodiment, an upper break line 40, a connecting break line 42, and a lower break line 50 are formed in the packaging body 1. However, it is not necessary to form an upper break line 40, a connecting break line 42, and a lower break line 50. As long as a horizontal break line 22 is formed at least in the middle part 5 of the peripheral surface 10, it is possible to prevent accidental opening of the packaging body 1 while easily removing the absorbent article 2 from the packaging body 1.

[0104] Furthermore, in the above embodiment, a disposable diaper with a belt is used as an example to illustrate the absorbent article 2, but the absorbent article 2 can also be a disposable diaper in the form of underwear, a sanitary napkin, a pet pad, etc. The horizontal break line 22 can also be formed along the boundary between the absorbent article disposed in the lower layer and the absorbent article disposed in the upper layer.

[0105] Furthermore, the various implementation methods described above can be combined without contradiction.
