Description

[Technical field]

[0001] The present invention relates to an interlocking package product for absorbent articles. [Background technology]

[0002] A package or individual package of an absorbent article containing a volatile functional agent is known. For example, Patent Document 1 discloses an individual package of an absorbent article, which includes an absorbent article folded in the longitudinal direction, and a package that stores the absorbent article in a storage space. The package forms a storage space by folding a packaging sheet constituting the package together with the absorbent article about one or more folding axes as base points, and has a pair of sealed regions formed by sealing the folded packaging sheet in the longitudinal direction on both longitudinal side portions. Each of the pair of sealed regions includes a plurality of sealed portions arranged intermittently in the longitudinal direction. The packaging sheet has a viscosity of 100 cc / m at 23°C. 2 The oxygen permeability in the thickness direction is 100 / day / atm or less. The package contains a chemical solution containing a volatile component and a solvent that retains the volatile component in the storage space. Therefore, in Patent Document 1, in order to ensure the function of the volatile component, an absorbent article containing the volatile component is contained in an individual package bag of a packaging sheet with enhanced barrier properties, thereby suppressing the evaporation of the volatile component.

[0003] For example, Patent Document 2 discloses an absorbent article container in which a stack of absorbent article packages is contained in a container sheet. In this absorbent article package, absorbent articles containing fragrances are individually packaged in a packaging sheet. When the container is placed in a front view, the horizontal length of the stack is C, the depth length of the stack is D, and the horizontal length of the storage space in the container that contains the stack is F, the dimensions of the container are (C 2 +D 2 ) 1 / 2 >F. The oxygen permeability of the storage sheet is lower than that of the packaging sheet, and is 200cc / m at 23°C. 2 / day / atm or less. Therefore, in order to ensure the function of the volatile fragrance, Patent Document 2 stores a large number of individually wrapped absorbent articles containing a volatile fragrance in a large bag of a storage sheet with enhanced barrier properties, thereby suppressing the evaporation of the fragrance.

[0004] [Patent Document 1] Patent No. 6463213 [Patent Document 2] Utility Model Registration No. 3246808 Summary of the Invention [Problem to be solved by the invention]

[0005] In Patent Document 1, one absorbent article is contained in an individual packaging bag of a packaging sheet. However, in order to make the bag easy to open, the sealing area is not completely sealed but is intermittently sealed. Therefore, in the bag, the volatile functional agent (volatile component) is likely to evaporate from the intermittent sealing. Therefore, when a user uses the absorbent article, there is a risk that the functional agent remaining in the absorbent article in the bag will be reduced. In that case, it may be difficult for the absorbent article to fully obtain the function of the functional agent.

[0006] In Patent Document 2, a large number of individually wrapped absorbent articles are stored in a packaging bag of a storage sheet. However, when the absorbent article is used, the bag is opened, which reduces the barrier properties of the bag and makes it easier for the volatile functional agent (fragrance) to evaporate. Therefore, if the absorbent article is not replaced frequently, there is a risk that the functional agent remaining in the absorbent article left in the bag will be reduced by the time the absorbent article is next used. In that case, it may be difficult for the absorbent article left in the bag to fully obtain the function of the functional agent.

[0007] An object of the present invention is to provide a linked package product for absorbent articles that can accommodate a plurality of absorbent articles containing a volatile functional agent while suppressing evaporation of the volatile functional agent from the absorbent articles. [Means for solving the problem]

[0008] One aspect of the present invention is as follows: A linked package product in which a plurality of packages are linked in a first direction, each of the plurality of packages includes an absorbent article containing a volatile functional agent and a packaging bag in which the absorbent article is enclosed, and the oxygen permeability of a sheet constituting the packaging bag is 200 cc / m at 23°C. 2 / day / atm or less, consolidated packaging products. Effect of the Invention

[0009] According to the present invention, it is possible to provide a linked packaged product for absorbent articles that can store a plurality of absorbent articles containing a volatile functional agent while suppressing evaporation of the volatile functional agent in the absorbent articles.

[Figure 6] 1A to 1C are diagrams illustrating a method for measuring the bonding strength of a packaged product according to an embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The present embodiment relates to the following aspects. [Aspect 1] A linked package product in which a plurality of packages are linked in a first direction, each of the plurality of packages comprising an absorbent article containing a volatile functional agent and a packaging bag in which the absorbent article is enclosed, and an oxygen permeability of a sheet constituting the packaging bag is 200 cc / m at 23°C. 2 / day / atm or less, consolidated packaging products.

[0012] This linked package product has multiple linked packages, and an absorbent article is enclosed in the packaging bag of each package, so that the product as a whole can contain multiple absorbent articles containing volatile functional agents. In addition, in this linked package product, the oxygen permeability of the packaging bag sheet is low (200cc / m at 23°C). 2 / day / atm or less), and therefore, due to its high gas barrier property, the volatile functional agent contained in the absorbent article is unlikely to evaporate to the outside of the packaging bag. As a result, when a user uses the absorbent article, the functional agent is likely to remain in the absorbent article in the packaging bag, so that the function of the functional agent is likely to be fully obtained. Furthermore, when the number of absorbent articles enclosed in the packaging bag of each package is small (for example, 1 to 5), when the user opens the packaging bag to use the first absorbent article, the remaining absorbent articles will be used without much time in between, and the absorbent articles in the packaging bag will be used up in a short period of time. For example, when the absorbent article is a sanitary napkin, the average number of uses is 3 to 4 on a busy day and 1 to 2 on a light day. Therefore, the absorbent articles enclosed in the packaging bag of each package will be used up in a short period of time (for example, 1 to 2 days). Therefore, not only the first absorbent article but also the remaining absorbent articles can be used in a state where the volatile functional agent evaporates to the outside with little time. Therefore, the evaporation of the volatile functional agent in the absorbent article can be suppressed. In addition, the user can easily feel the effect of the volatile functional agent. Therefore, it is possible to provide a linked package product that can store a plurality of absorbent articles containing a volatile functional agent while suppressing the evaporation of the volatile functional agent in the absorbent articles.

[0013] However, because a large bag such as that in Patent Document 2 takes up space, it may be difficult to sell it in a small store or to store it at home. In that case, sellers and users may shy away from multiple absorbent articles stored in the large bag. However, in the present linked packaged product, each package contains a small number of absorbent articles (e.g., 1 to 5), so it is small, and therefore the linked packaged product is also a multiple packaged product connected in one direction, so it is compact and does not take up space, making it easy to sell it in a small store or to store it at home.

[0014] [Aspect 2] 2. The linked packaged product according to aspect 1, wherein the number of the absorbent articles included in each of the plurality of packages is any number between 1 and 5.

[0015] In this linked package product, the number of absorbent articles enclosed in the packaging bag of each package is small (1 to 5). Therefore, even if the packaging bag of the package is opened when the first absorbent article in each package is used, the remaining absorbent articles are used without much time in between, so that the small number of absorbent articles in the packaging bag can be used up in a short period of time. Therefore, not only the first absorbent article but also the remaining absorbent articles can be used in a state where the volatile functional agent evaporates to the outside less. Therefore, the evaporating of the volatile functional agent in the absorbent article can be suppressed. And, the user can easily realize the effect of the volatile functional agent. In addition, since the number of absorbent articles contained in each package is small (1 to 5), the linked package product does not take up much space, and it is easy to sell them in a small sales area or store them at home.

[0016] [Aspect 3] The linked packaged product according to aspect 1 or 2, wherein in each of the plurality of packaged products, the absorbent article in the packaging bag is contained in an individual packaging bag, and the oxygen transmission rate of the sheet constituting the individual packaging bag is greater than the oxygen transmission rate of the sheet constituting the packaging bag.

[0017] In this linked package product, the oxygen permeability of the packaging bag sheet in each package is low and the gas barrier properties are high, so that an easy-to-open material (e.g., a low-melting-point film or nonwoven fabric such as polyethylene or polypropylene), i.e., a material with a high oxygen permeability rate, can be used for the sheet material of the individual packaging bag of the absorbent article inside. This makes it possible to easily open the individual packaging bag during use while suppressing the evaporation of volatile functional agents in the absorbent article. In this case, the sound of opening the individual packaging bag can be reduced, so that it is unlikely to be noticed by people around and the user is unlikely to feel embarrassed.

[0018] [Aspect 4] The linked packaging product according to any one of aspects 1 to 3, wherein in each of the plurality of packaged products, the packaging bag includes a pair of horizontal joints located at both ends in the first direction and sealing the both ends of the packaging bag, and a vertical joint extending from one of the pair of horizontal joints to the other, and the joint strength in an overlapping region where each of the pair of horizontal joints overlaps with the vertical joint is weaker than the joint strength in a region of each of the pair of horizontal joints that does not overlap with the vertical joint.

[0019] In this linked package product, the joint strength in the overlapping areas where each of the pair of horizontal joints overlaps with the vertical joint in the packaging bag of each packaged product is weaker than the joint strength of the other joints. Therefore, the overlapping areas are likely to become the starting point for opening the packaging bag when opening it. Therefore, it is possible to make the packaging bag easier to open when in use while suppressing the evaporation of the volatile functional agent in the absorbent article. In this case, the sound generated when opening the packaging bag can be reduced, so that it is less likely to be noticed by people around and the user is less likely to feel embarrassed.

[0020] [Aspect 5] The linked packaged product according to any one of aspects 1 to 4, wherein in each of the plurality of packaged products, the packaging bag includes a pair of horizontal joints located at both ends in the first direction and sealing the both ends of the packaging bag, and a portion of the pair of horizontal joints has a non-jointed portion.

[0021] In this linked package product, a part of the pair of lateral joints of the packaging bag has a non-jointed portion that is not joined, so that air inside the packaging bag can be discharged from the non-jointed portion, thereby suppressing the evaporation of the volatile functional agent in the absorbent article, and preventing the packaging bag from filling with the volatile functional agent and causing the packaging bag to expand excessively, and ultimately causing the packaging bag to burst and dissipate the functional agent.

[0022] [Aspect 6] A linked packaged product according to any one of aspects 1 to 5, wherein in each of the plurality of packaged products, the packaging bag includes a pair of horizontal joints located at both ends in the first direction and sealing the both ends of the packaging bag, each of the pair of horizontal joints extending along a second direction perpendicular to the first direction and having a plurality of continuous patterns spaced apart in the first direction.

[0023] In the linked packaged product, each horizontal joint extends along a second direction perpendicular to the first direction and includes a plurality of continuous patterns spaced apart in the first direction. The continuous patterns can improve the sealing performance of the packaging bag. Even if a portion of the plurality of continuous patterns at the horizontal joint comes off during the manufacture or sale of the linked packaged product, the remaining portion of the plurality of continuous patterns can maintain the sealing performance. In particular, when one of the ends of the plurality of linked packaged products is cut between the horizontal joints in the linked packaged product, the sealing performance at the horizontal joints is easily maintained. This can suppress the evaporation of a volatile functional agent in the absorbent article.

[0024] Furthermore, by including a continuous pattern of multiple lines spaced apart in the first direction, the horizontal joint 5 can make it easier to open the packaging bag of the packaged product compared to a case where the horizontal joint 5 includes a single continuous pattern made up of multiple lines. This makes it easier to open the packaging bag during use while suppressing evaporation of the volatile functional agent in the absorbent article 3. In this case, the sound made when opening the packaging bag can be reduced, making it less likely to be noticed by people around and less likely to embarrass the user.

[0025] [Aspect 7] A linked packaged product according to any one of aspects 1 to 6, wherein in each of the plurality of packages, the absorbent articles in the packaging bag are not contained in individual packaging bags.

[0026] In this linked package product, the absorbent articles in the packaging bags of each package are not contained in individual packaging bags, but are directly contained in the packaging bag. Therefore, after opening the packaging bag, the absorbent articles can be used immediately, that is, before the volatile functional agent has evaporated significantly. In addition, the absorbent articles can be easily used, and the functional agent can easily fill the packaging bag, making it easy to feel the function of the functional agent when opening the bag.

[0027] [Aspect 8] The linked package product according to any one of aspects 1 to 7, wherein the sheet constituting the packaging bag is composed of a plurality of layers, and a layer constituting an outer surface of the packaging bag among the plurality of layers includes a film with low oxygen permeability.

[0028] In this linked package product, the layer constituting the outer surface of the packaging bag contains a film with low oxygen permeability (e.g., polyethylene terephthalate), which enhances gas barrier properties and makes it difficult for the volatile functional agent in the packaging bag to escape to the outside, while protecting the absorbent article from the outside air. This makes it difficult for the functionality of the absorbent article containing the functional agent to deteriorate until the user opens the packaging bag.

[0029] [Aspect 9] The linked packaged product according to any one of aspects 1 to 8, wherein the sheet constituting the packaging bag is composed of a plurality of layers, and a layer constituting the inner surface of the packaging bag among the plurality of layers includes a film having a low melting point.

[0030] In this linked package product, the layer constituting the inner surface of the packaging bag contains a film with a low melting point (e.g., polyethylene), so by using the inner surface of the packaging bag as the joint surface of the joint, the joint strength can be increased. This increases the gas barrier property, making it difficult for the volatile functional agent in the packaging bag to escape to the outside, and making it difficult for the function of the absorbent article containing the functional agent to decrease until the user opens the packaging bag.

[0031] [Aspect 10] A linked packaging product according to any one of aspects 1 to 9, wherein in each of the plurality of packaged products, the absorbent articles in the packaging bag are contained in an individual packaging bag, the individual packaging bag is located at both ends in a second direction perpendicular to the first direction, and includes a pair of individual packaging horizontal joints that seal the both ends of the individual packaging bag, and (the distance between both end edges of the packaging bag in the second direction)<(the distance between the outer edges of the pair of individual packaging horizontal joints in the second direction).

[0032] In this linked packaged product, the distance (width) between both end edges in the second direction of the packaging bag is smaller than the distance between the outer end edges in the second direction of a pair of individual package horizontal joints. Therefore, the individual package bag containing the absorbent article is enclosed in the packaging bag with each of the pair of individual package horizontal joints located at both end edges in the second direction folded inward. Therefore, even after the packaging bag is opened, the volatile functional agent is unlikely to evaporate from each of the pair of individual package horizontal joints. Therefore, the functional agent is likely to remain in the absorbent article not only before but also after the packaging bag is opened, making it easier for the functional agent to fully function.

[0033] [Aspect 11] 11. The linked packaged product of any one of the preceding aspects, wherein the functional agent comprises at least one of a cooling agent, a warming agent, an antibacterial agent, and a fragrance.

[0034] This linked package product contains at least one of a cooling sensation agent, a warming sensation agent, an antibacterial agent, and a fragrance (hereinafter, simply referred to as "cooling sensation agent, etc.") as a functional agent. This makes it possible to store an absorbent article containing a volatile cooling sensation agent, etc. in the package while suppressing the evaporation of the volatile cooling sensation agent, etc. from the absorbent article. This makes it easier to fully obtain the function of the cooling sensation agent, etc.

[0035] The linked packaged product of absorbent articles according to this embodiment will be described below. The linked packaged product is one of the product forms of absorbent articles, and is a product in which a plurality of packages in which absorbent articles are individually packaged are linked in one direction. The linked packaged product is, for example, displayed in a store, and the number of packages desired by the purchaser is separated from the linked packaged product and sold to the purchaser.

[0036] In this embodiment, a sanitary napkin is used as an example of an absorbent article. However, the linked package product of the present invention can be applied to other absorbent articles, such as panty liners, incontinence pads, disposable diapers, etc., without departing from the scope of the subject matter of the present invention.

[0037] 1(a), 1(b), and 1(c) respectively show a bottom view, a plan view, and a side view of a configuration example of a linked packaged product 1 of an absorbent article according to an embodiment. With reference to FIGS. 1(a), 1(b), and 1(c), the linked packaged product 1 includes a plurality of packaged items 2. These plurality of packaged items 2 are linked to each other in one direction. In this embodiment, the linked packaged product 1 includes eight packaged items 2. The direction in which the plurality of packaged items 2 are linked to each other is referred to as a first direction, and the direction perpendicular to the first direction is referred to as a second direction.

[0038] The package 2 includes an absorbent article 3 containing a volatile functional agent, and a packaging bag 4 in which the absorbent article 3 is enclosed. In this embodiment, the package 2 has a vertical direction of the package 2 along a first direction, and a horizontal direction along a second direction perpendicular to the vertical direction. The packaging bag 4 includes a vertical joint 6 extending along the vertical direction, and a pair of horizontal joints 5 extending along the horizontal direction at both ends of the vertical direction of the package 2, and is sealed by them. Examples of sealing of the vertical joint 6 and the pair of horizontal joints 5 include fusion (for example, heat, ultrasonic, etc.) and adhesive bonding. Adjacent packages 2 are connected to each other via weakened lines 7 such as perforations provided between adjacent horizontal joints 5. Individual packages 2 are obtained by cutting the linked package product 1 along the weakened lines 7.

[0039] Here, the linked packaged product 1 is manufactured, for example, by the following method. First, for a strip-shaped sheet for a packaging bag 4 extending in a first direction (machine direction), both ends in a second direction (transverse direction) are overlapped and joined at a vertical joint 6 extending along the first direction to form a cylindrical sheet. Next, an absorbent article 3 is placed in the cylindrical sheet. Next, the front and rear of the absorbent article 3 in the cylindrical sheet in the first direction are pressed, respectively, and joined at a pair of horizontal joints 5 extending along the second direction to form a packaged product 2. Then, weakened lines 7 extending along the second direction are formed at the midpoints in the first direction of the horizontal joints 5 of adjacent packages 2. In this way, the linked packaged product 1 is formed. However, the manufacturing method is not limited to this example.

[0040] Examples of the volatile functional agent include a cooling agent, a warming agent, an antibacterial agent, and a fragrance. The functional agent will be described in detail later. In this embodiment, the absorbent article 3 is a sanitary napkin, and the details thereof will be described later.

[0041] The oxygen permeability of the sheet constituting the packaging bag 4 is 200 cc / m at 23°C. 2 / day / atm or less. The low oxygen permeability of the sheet, i.e., the high gas barrier property, makes it difficult for the volatile functional agent contained in the absorbent article 3 to evaporate to the outside of the packaging bag 4. The oxygen permeability of the sheet is preferably 100 cc / m at 23°C. 2 / day / atm or less, and more preferably 50 cc / m 2 / day / atm or less. However, oxygen permeability is measured according to the coulometric method under the conditions of 23°C and 0% RH.

[0042] In this embodiment, the material of the packaging bag 4 is not particularly limited as long as it satisfies the above oxygen permeability, and may be a synthetic resin film. The synthetic resin film may be composed of a single layer or multiple layers. Examples of the synthetic resin film include a film formed of multiple layers such as polyethylene terephthalate (PET) / polyethylene (PE), and a film composed of a single layer such as an ethylene-vinyl alcohol copolymer (EVOH) film. Alternatively, layers of other substances may be laminated to these films to impart other properties.

[0043] In this way, the linked packaged product 1 has a plurality of linked packaged items 2, and an absorbent article 3 is enclosed in the packaging bag 4 of each packaged item 2, so that the linked packaged product 1 can accommodate a plurality of absorbent articles 3 containing a volatile functional agent as a whole. In addition, in the linked packaged product 1, the oxygen permeability of the sheet of the packaging bag 4 is low (200 cc / m at 23°C). 2 / day / atm or less), and therefore, due to its high gas barrier properties, the volatile functional agent contained in the absorbent article 3 is less likely to evaporate to the outside of the packaging bag 4. As a result, when a user uses the absorbent article 3, the functional agent tends to remain in the absorbent article 3 inside the packaging bag 4, making it easier for the functional agent to fully function.

[0044] In the linked packaged product 1, the number of absorbent articles enclosed in the packaging bag of each package is small (for example, 5 or less, or 2 or less), so when a user opens the packaging bag 4 to use the first absorbent article 3, the remaining absorbent articles 3 are used without much time in between, and the absorbent articles 3 in the packaging bag 4 can be used up in a short period of time. For example, when the absorbent articles 3 are sanitary napkins, the average number of uses is 3 to 4 on a busy day and 1 to 2 on a light day. Therefore, the absorbent articles 3 enclosed in the packaging bag 4 of each package 2 are used up in a short period of time (for example, 1 to 2 days). Therefore, not only the first absorbent article 3 but also the remaining absorbent articles 3 can be used in a state where the volatile functional agent evaporates little to the outside. Therefore, the evaporating of the volatile functional agent in the absorbent article 3 can be suppressed. And the user can easily realize the effect of the volatile functional agent.

[0045] Therefore, it is possible to provide a linked package product 1 that can store a plurality of absorbent articles 3 containing a volatile functional agent while suppressing evaporation of the volatile functional agent from the absorbent articles 3.

[0046] However, a large bag like that of Patent Document 2 takes up space, which may make it difficult to sell in a small storefront or store at home. This may cause sellers and users to shy away from multiple absorbent articles 3 stored in the large bag. However, in the present linked packaged product 1, each packaged article 2 is small because it contains a small number of absorbent articles 3 (e.g., 1 to 5 pieces), and therefore the linked packaged product 1 is also a multiple packaged article 2 linked in one direction, so it is compact and does not take up much space, making it easy to sell in a small storefront or store at home.

[0047] In a preferred embodiment of this embodiment, the number of absorbent articles 3 included in each of the multiple packages 2 is any number between 1 and 5. In the example of FIG. 1, the number of absorbent articles 3 in the package 2 is two. Therefore, even if the packaging bag 4 of the package 2 is opened when the first absorbent article 3 in each package 2 is used, the remaining absorbent articles 3 are used without much time in between, so that the small number of absorbent articles 3 in the packaging bag 4 can be used up in a short period of time. Therefore, not only the first absorbent article 3 but also the remaining absorbent articles 3 can be used in a state where the volatile functional agent evaporates to the outside less. Therefore, the evaporating of the volatile functional agent in the absorbent article 3 can be suppressed. And the user can easily realize the effect of the volatile functional agent. Since the number of absorbent articles 3 contained in each package 2 is small (1 to 5), the linked package product 1 does not take up much space, and it is easy to sell it in a small sales area or store it at home.

[0048] In a preferred embodiment of this embodiment, the packaging bag 4 of each packaged product 2 has a non-jointed portion in a part of the pair of horizontal joints 5. That is, the horizontal joints 5 seal the openings at both ends of the cylindrical packaging bag 4 by joining them with fusion parts by fusion or adhesive parts by adhesive, but have a non-jointed portion in a part of the joint. However, the non-jointed portion is a gap or hole that penetrates the inside and outside of the packaged product 2, and the non-jointed portion includes small ones that cannot be seen with the naked eye. Therefore, air in the packaging bag 4 can be discharged from the non-jointed portion. This can suppress the evaporation of the volatile functional agent in the absorbent article 3, while suppressing the packaging bag 4 from being filled with the volatile functional agent, causing the packaging bag 4 to expand too much, and ultimately the packaging bag 4 to burst and disperse the functional agent.

[0049] Next, the absorbent article 3 according to the embodiment will be described. Fig. 2 and Fig. 3 are diagrams showing an example of the configuration of the absorbent article 3 according to the embodiment. Fig. 2 is a plan view showing the absorbent article 3 in an unfolded state. Fig. 3 is a schematic cross-sectional view of the absorbent article (excluding the individual packaging bag 21) in Fig. 2 taken along the line CW.

[0050] The absorbent article 3 has a longitudinal direction L, a width direction W, and a thickness direction T that are perpendicular to each other. In the absorbent article 3 depicted in FIG. 21, the upper and lower sides of the figure are the front and rear sides of the longitudinal direction L, the left and right sides are the left and right sides of the width direction W, and the front and back sides of the paper are the upper and lower sides of the thickness direction T. The absorbent article 3 has a longitudinal centerline CL (virtual line) that passes through the center of the width direction W and extends in the longitudinal direction L, and a widthwise centerline CW (virtual line) that passes through the center of the longitudinal direction L and extends in the width direction W. The directions and sides toward the longitudinal centerline CL are respectively the inward and inner sides of the width direction W, and the directions and sides away from the longitudinal centerline CL are respectively the outward and outer sides of the width direction W. Meanwhile, the directions and sides toward the widthwise centerline CW are respectively the inward and inner sides of the longitudinal direction L, and the directions and sides away from the longitudinal direction L are respectively the outward and outer sides of the longitudinal direction L. Viewing the absorbent article 3 placed on a plane including the longitudinal direction L and width direction W from above in the thickness direction T is called a planar view, and the shape as understood in a planar view is called a planar shape. Any direction within a plane including the longitudinal direction L and width direction W is called a planar direction. When a wearer wears the absorbent article 3, the sides that are relatively closer to the wearer's skin surface in the thickness direction T are called the skin side and the non-skin side, respectively. These definitions are also commonly used for each material of the absorbent article 3 and in an individually packaged state.

[0051] In this embodiment, the absorbent article 3 (excluding the wing portions) has a generally rectangular shape that is long in the longitudinal direction L and short in the width direction W in a plan view, and both ends of the longitudinal direction L have a generally semicircular shape. The shape of the absorbent article 3 is not particularly limited as long as it is long in the longitudinal direction L and short in the width direction W, and examples of the shape include a rounded rectangle, an ellipse, a gourd shape, and an hourglass shape. The absorbent article 3 has a pair of wing portions 17 that extend outward on both sides in the width direction W from the generally rectangular portion. The wing portions 17 have a generally trapezoidal shape. The shape is not particularly limited, and may be, for example, a semicircle or a semiellipse.

[0052] In this embodiment, the absorbent article 3 includes a top sheet 12, an absorbent 14, a back sheet 13, and a clothing fastening part 20. The top sheet 12 is a liquid-permeable sheet and constitutes the skin-side surface of the absorbent article 3. The absorbent 14 is a liquid-absorbent and liquid-retentive material and is located on the non-skin side of the top sheet 12 and on the skin side of the back sheet 13. In this embodiment, the absorbent 14 includes an absorbent core 14a (e.g., pulp fiber, superabsorbent polymer) and a core wrap sheet 14b that contains it. The back sheet 13 is a liquid-impermeable sheet and constitutes the non-skin side surface of the absorbent article 3 in this embodiment. The clothing fastening part 20 is an adhesive that adheres the absorbent article 3 to the skin-side surface of underwear and is located on the non-skin side surface of the back sheet 13 in this embodiment. Therefore, in the absorbent article 3, the top sheet 12, the absorbent 14, the back sheet 13, and the clothing fastening part 20 are laminated in this order in the thickness direction T. The absorbent article 3 may further include an outer sheet on the non-skin side of the back sheet 13, and may further include a liquid-permeable second sheet between the top sheet 12 and the absorbent body .

[0053] In this embodiment, the absorbent article 3 further includes a pair of side sheets 16 and a pair of clothing fastening parts 19. The pair of side sheets 16 are hydrophilic or water-repellent sheets, and in this embodiment, are located on both sides of the top sheet 12 in the width direction W. The pair of clothing fastening parts 19 are adhesives that adhere the pair of wing parts 17 to the non-skin side of the underwear, and in this embodiment, are located on the non-skin side surfaces of the back sheet 13 of the pair of wing parts 17. The pair of side sheets 16 may include a pair of leak-proof walls extending along the longitudinal direction L on the inner side in the width direction W.

[0054] In this embodiment, the absorbent article 3 further includes compressed sections 18 formed by squeezing in the thickness direction T from the top sheet 12 toward the absorbent body 14. The compressed sections 18 include compressed sections 18 located approximately in the center of the longitudinal direction L, extending along the longitudinal direction L, and provided on both sides of the longitudinal centerline CL in the width direction W, and compressed sections 18 located approximately in the center of the width direction W, extending along the width direction W, and provided on both sides of the longitudinal centerline CW in the longitudinal direction L. The shape and number of compressed sections 18 are arbitrary, and the absorbent article 3 does not need to include at least one of the compressed sections 18.

[0055] In this embodiment, the top sheet 12, absorbent body 14 and back sheet 13 are each joined to each other with an adhesive, the top sheet 12 and a pair of side sheets 16 are joined by ultrasonic sealing or heat sealing, and the top sheet 12, a pair of side sheets 16 and back sheet 13 at the peripheral portion of the absorbent article 3 are joined by ultrasonic sealing or heat sealing.

[0056] In this embodiment, the absorbent article 3 is contained in an individual packaging bag 21. In the developed state of the absorbent article 3 as shown in FIG. 2, the individual packaging bag 21 is disposed on the non-skin side of the absorbent article 3, and is removably joined to the absorbent article 3 by, for example, a garment fastening part 20. When the developed absorbent article 3 is contained in the individual packaging bag 21, first, both sides of the absorbent article 3 in the width direction W are folded inward at a pair of fold lines FL1 located on both sides of the absorbent article 3 in the width direction W and extending along the longitudinal direction L. As a result, first, the absorbent article 3 is folded in three in the width direction W. Next, the adhesive 23 is applied linearly along the width direction W to the front end of the individual packaging bag 21 in the longitudinal direction L. Then, at a fold line FL2 located on the rear side of the absorbent article 3 in the longitudinal direction L and extending along the width direction W, the rear side of the absorbent article 3 in the longitudinal direction L is folded inward together with the individual packaging bag 21. Next, the front portion of the absorbent article 3 in the longitudinal direction L is folded inward together with the individual packaging bag 21 at a fold line FL3 located at the front side of the absorbent article 3 in the longitudinal direction L and extending along the width direction W. As a result, the absorbent article 3 is folded in thirds together with the individual packaging bag 21 in the longitudinal direction L, and the front end of the individual packaging bag 21 in the longitudinal direction L is bonded to the rear end thereof by the adhesive 23. That is, the absorbent article 3 is wrapped in the individual packaging bag 21. Then, both ends of the individual packaging bag 21 in the width direction W are sealed by a pair of individual packaging horizontal joints 22. As a result, the absorbent article 3 contained in the individual packaging bag 21 is formed.

[0057] 4 is a diagram showing an example of a configuration in which an absorbent article 3 according to an embodiment is contained in an individual packaging bag 21. As shown in the figure, the absorbent article 3 is folded in thirds in the longitudinal direction L together with the individual packaging bag 21 at fold lines FL2 and FL3. A pair of individual packaging horizontal joints 22 are located at both ends of the individual packaging bag 21 in the width direction W, and seal both ends of the individual packaging bag 21. Examples of the individual packaging horizontal joints 22 include fusion-bonded parts (for example, by heat, ultrasonic waves, etc.) and adhesive-bonded parts. The adhesive 23 bonds the front end and rear end of the individual packaging bag 21 in the longitudinal direction L. The pair of individual packaging horizontal joints 22 and the adhesive 23 are removable when used.

[0058] In a preferred embodiment of the present invention, the oxygen transmission rate of the sheet constituting the individual packaging bag 21 that contains the absorbent article 3 is greater than the oxygen transmission rate of the sheet constituting the packaging bag 4. In other words, the oxygen transmission rate of the sheet constituting the individual packaging bag 21 is greater than or equal to 200 cc / m at 23° C. 2 / day / atm. However, as mentioned above, the oxygen transmission rate is measured according to the coulometric method under the conditions of 23°C and 0% RH.

[0059] In the linked package product 1, since the sheet of the packaging bag 4 in each packaged product 2 has low oxygen permeability and high gas barrier property, an easy-to-open material can be used for the sheet of the individual packaging bag 21 of the absorbent article 3 inside the linked package product 1, even if the material has low gas barrier property. Examples of easy-to-open materials include low-melting point films such as polyethylene (PE) and polypropylene (PP) and nonwoven fabrics. In this way, by using an easy-to-open sheet of the individual packaging bag 21 inside the sheet of the packaging bag 4 with high gas barrier property, it is possible to make the individual packaging bag 21 easy to open during use while suppressing the evaporation of the volatile functional agent in the absorbent article 3. In this case, the sound of opening the individual packaging bag 21 can be reduced, so that it is unlikely to be noticed by people around you and the user is unlikely to feel embarrassed.

[0060] In another aspect of this embodiment, in each of the multiple packaged products 2, the absorbent article 3 in the packaging bag 4 may not be contained in an individual packaging bag 21. Therefore, the individual packaging bag 21 may not be present. Even in this case, since the oxygen permeability of the packaging bag 4 is low, the volatile functional agent can be retained in the packaging bag 4, and evaporation of the functional agent can be suppressed.

[0061] In this case, the absorbent article 3 in the packaging bag 4 of each packaged product 2 is not contained in an individual packaging bag 21 but is contained directly in the packaging bag 4, so that after opening the packaging bag 4, the absorbent article 3 can be used immediately, that is, in a state where the volatile functional agent has not evaporated much. Also, the use of the absorbent article 3 can be started easily, and since the functional material easily fills the packaging bag 4, the function of the functional agent can be easily felt when opening it.

[0062] The absorbent article 3 includes a functional layer 15 having a volatile functional agent. The functional layer 15 may be an independent layer containing a functional agent (for example, a sheet containing a functional agent), or may be a region on a sheet constituting the absorbent article 3, such as the top sheet 12, in which the functional agent is disposed. The functional layer 15 is not limited to the region where the functional agent is applied, and if the applied functional agent migrates to another region after application, the other region may also become the functional layer 15. In this embodiment, the functional layer 15 is disposed on the non-skin side surface of the top sheet 12. The basis weight of the functional agent in the functional layer 15 is, for example, 0.001 to 10 g / m 2 and preferably 0.003 to 5 g / m 2 , more preferably 0.005 to 2.5 g / m 2 Examples include:

[0063] The position of the functional layer 15 is not particularly limited as long as it is within the absorbent article 3. Examples of the position in the thickness direction T include at least one of the non-skin side and / or skin side of the top sheet 12, the non-skin side and / or skin side of the core wrap sheet 14b of the absorbent body 14, the skin side and / or inside of the absorbent core 14a, and the non-skin side and / or skin side of the back sheet 13. In addition, if a second sheet is provided, the non-skin side and / or skin side of the second sheet may be used. Examples of the range in the width direction W include both ends of the sheet where the functional layer 15 (functional agent) is arranged (for example, a range of 5 to 20% of the width of the specified sheet from both ends of the above-mentioned specified sheet), the center (for example, a range of 5 to 20% of the width of the specified sheet on both sides from the longitudinal center line CL), and the entire range (for example, from one end to the other end of the specified sheet). Examples of the range in the longitudinal direction L include both ends of the sheet on which the functional layer 15 (functional agent) is disposed (e.g., a range of 5 to 20% of the length of the specified sheet from both ends of the specified sheet), the center (e.g., a range of 5 to 20% of the length of the specified sheet on both sides from the widthwise centerline CW), and the entire range (e.g., from one end to the other end of the specified sheet). In this embodiment, the position of the functional layer 15 (functional agent) is the non-skin side surface of the top sheet 12 in the thickness direction T, and the entire range of the top sheet 12 in the longitudinal direction L and width direction W (from one end to the other end of the top sheet 12 in each of the longitudinal direction L and width direction W).

[0064] As the volatile functional agent in the functional layer 15, any functional agent according to the desired action can be adopted. As such functional agents, as described above, for example, cooling agents, warming agents, antibacterial agents, and fragrances can be mentioned. For example, in a plan view, one type of functional agent (e.g., a cooling agent) may be disposed in a portion of the functional layer 15, and another type of functional agent (e.g., a fragrance) may be disposed in another portion, or multiple types of functional agents may be disposed in the same portion. In this embodiment, a cooling agent is used.

[0065] In a preferred embodiment of the present invention, the functional agent (functional layer 15) contains at least one of a cooling agent, a warming agent, an antibacterial agent, and a fragrance (hereinafter, simply referred to as "cooling agent, etc."). This makes it possible to store multiple absorbent articles containing volatile cooling agents, etc. in the package while suppressing the evaporation of the volatile cooling agents, etc. from the absorbent articles. This makes it easier to fully obtain the function of the cooling agents, etc.

[0066] The cooling sensation agent that can be used as the functional agent contains a cooling sensation component that stimulates the cold sensation receptors of the wearer's skin without absorbing heat itself, thereby making the wearer feel a cooling sensation. Examples of the cooling sensation component include menthol (e.g., l-menthol, etc.); menthol derivatives (e.g., menthyl lactate, menthone glycerin acetal (MGA), etc.); methyl salicylate; camphor, cucumber extract, and essential oils derived from plants (e.g., mint, eucalyptus, nutmeg, etc.). The cooling sensation agent may also be one that lowers the surrounding temperature by the heat of vaporization. Examples of such cooling sensation agents include alcohol (e.g., ethanol, etc.). These components may be used alone or in combination of two or more.

[0067] When the cooling agent is applied to a predetermined sheet by coating or the like, it may contain a solvent component that dissolves or disperses the cooling component together with the cooling component. Examples of such solvent components include lipophilic solvents and hydrophilic solvents. Examples of lipophilic solvents include oils and fats such as natural oils (e.g., fatty acid esters such as triglycerides, coconut oil, linseed oil, etc.) and hydrocarbons (e.g., paraffin, etc.). On the other hand, examples of hydrophilic solvents include water and alcohol, and examples of alcohol include lower alcohols (e.g., methanol, ethanol, ethylene glycol, glycerin, etc.) and higher alcohols (e.g., capryl alcohol, lauryl alcohol, etc.). Among these solvents, it is preferable to use lipophilic solvents such as oils and fats or alcohols in terms of ease of controlling volatility, and it is more preferable to use lipophilic solvents such as oils and fats in terms of ease of maintaining the absorption performance of the absorbent article. After application of such a solvent to a substrate, the solvent may remain in a solidified or semi-solidified state at the application site, or the solvent may volatilize and only the solute may remain.

[0068] When the cooling sensation agent contains a solvent component, the concentration of the cooling sensation component is preferably 0.0001% by mass or more and 5.0% by mass or less, more preferably 0.0005% by mass or more and 3.0% by mass or less, and even more preferably 0.1% by mass or more and 1.0% by mass or less, from the viewpoint of the cooling sensation effect.

[0069] The warming agent that can be used as the functional agent contains a warming component that stimulates the thermosensory receptors of the wearer's skin without generating heat itself, thereby making the wearer feel a sense of warmth. From the viewpoint of providing a sense of security to the wearer, the warming component is preferably a compound derived from a plant, such as capsaicin, vanillyl alcohol alkyl ether derivatives (e.g., vanillyl ethyl ether, vanillyl butyl ether, vanillyl pentyl ether, vanillyl hexyl ether, etc.), ginger extract, ginger oil, etc. Among these compounds, vanillyl alcohol alkyl ether derivatives, ginger extract, ginger oil, etc. are preferably used from the viewpoint of irritation to the skin. These compounds may be used alone or in combination of two or more kinds. The warming agent may contain a solvent component that dissolves the warming component, and the solvent component is the same as that of the cooling agent.

[0070] The antibacterial agent that can be used as a functional agent contains an antibacterial component. Examples of the antibacterial component include those containing naturally derived antibacterial components (e.g., daunsiri component, phellodendron bark extract, olive leaf extract, chamomile extract, kumazasa extract, Japanese pepper extract, perilla extract, dokudami extract, hop extract, eucalyptus extract, mugwort extract, etc.) and synthetic antibacterial components (e.g., ethylhexylglycerin, etc.). These components may be used alone or in combination of two or more types. The antibacterial agent may contain a solvent component that dissolves the antibacterial component, and the solvent component is the same as in the case of the cooling agent.

[0071] The fragrance that can be used as a functional agent is not particularly limited as long as it can be used in sanitary products, and for example, any of natural fragrances and synthetic fragrances may be used, two or more fragrances may be used in combination, and may be dissolved in one or more solvents. Examples of natural fragrances include anise, basil, bergamot, camphor, chamomile, citronella, clove, eucalyptus, grapefruit, rose, jasmine, peppermint, lemongrass, ginger, lavender, ylang-ylang, mint, orange, sage, rosemary, lime, etc. Examples of synthetic fragrances include terpene hydrocarbons such as pinene and limonene; terpene alcohols such as linalool, geraniol, nerol, citronellol, dihydromyrcenol, terpineol, menthol, borneol, and cedrol; alicyclic alcohols such as amber core; aromatic alcohols such as phenylethyl alcohol and eugenol; synthetic sandals such as sandalwood and mysole core; ethers such as rose oxide and anethole; terpene aldehydes such as citral and citronellal; aromatic aldehydes such as cinnamic aldehyde, helional, vanillin, and ethyl vanillin; terpene ketones such as camphor, carvone, ionones, damascone, and damascenone; aromatic ketones such as acetophenone and raspberry ketone, and acetate esters such as ethyl acetate, linalyl acetate, and benzyl acetate; propionate esters such as methyl propionate; salicylic acid esters such as methyl salicylate; and anthranilate esters such as methyl anthranilate. The flavoring may contain a solvent component, and the solvent component is the same as that of the cooling agent.

[0072] As the fragrance, an insect repellent fragrance may be used. The insect repellent fragrance is a repellent (insect repellent) against pests such as mosquitoes, moths, midges, and flies, and is a fragrance of a synthetic compound or a natural plant extract. As the insect repellent fragrance, for example, citronellal, DEET (N,N-diethyl-3-methylbenzamide), sesquiterpene, ethyl butyl acetyl aminopropionate, picaridin, pyrethroid, cinnamon, rosemary, lavender, peppermint, eucalyptus, etc. can be used. The insect repellent fragrance can be appropriately selected according to the target pests and the desired aroma. The insect repellent fragrance may contain a solvent component, and the solvent component is the same as that of the cooling agent.

[0073] Fig. 5 is a diagram showing an example of a mode in which an absorbent article 3 according to an embodiment is contained in a packaging bag 4 of a linked packaged product 1. The example in this figure shows an absorbent article 3 contained in an individual packaging bag 21 (shown in the upper part of Fig. 5) and a state in which the absorbent article 3 is contained in a packaged product 2 (packaging bag 4) (shown in the lower part of Fig. 5).

[0074] The length d1 of the absorbent article 3 in the width direction W contained in the individual packaging bag 21 is larger than the length d2 of the packaged product 2 (packaging bag 4) in the second direction (d1>d2). Therefore, in order to contain the absorbent article 3 in the packaged product 2 (packaging bag 4), both ends in the width direction W of the individual packaging bag 21, for example, roughly a pair of individual packaging horizontal joints 22, are folded back inward in the width direction W, as shown by the arrows. Then, with both ends in the width direction W of the individual packaging bag 21 folded back, the absorbent article 3 is contained in the packaging bag 4 in which one of the pair of horizontal joints 5 is formed (sealed) and the other is not formed, from the side where it is not formed. At that time, the absorbent article 3 is contained so that the longitudinal direction L / width direction W of the absorbent article 3 is aligned with the first direction / second direction of the packaged product 2 (packaging bag 4). After containing, the other of the pair of horizontal joints 5 is formed (sealed). Thereby, the packaging bag 4 in which the absorbent article 3 is enclosed is formed. Here, in the individual packaging bag 21 containing the absorbent article 3, both folded ends in the width direction W attempt to return to their original state and spread outward in the width direction W. Therefore, both ends in the width direction W are pressed against the inner surface of the package 2 (packaging bag 4). This restricts the movement of the absorbent article 3 inside the package 2 (packaging bag 4).

[0075] In a preferred embodiment of the present invention, in the packaging bag 4 of each packaged product 2, the joint strength in the overlapping region 5a where each of the pair of horizontal joints 5 and the vertical joint 6 overlap is weaker than the joint strength in the region where each of the pair of horizontal joints 5 does not overlap with the vertical joint 6. Here, as described above, in the linked packaged product 1, the vertical joint 6 is first formed along the first direction, and then the pair of horizontal joints 5 is formed along the second direction. When the horizontal joints 5 are formed by fusion (for example, heat, ultrasound, etc.), heat or ultrasound is less likely to be transmitted to the overlapping region 5a where the horizontal joints 5 and the vertical joints 6 overlap, compared to the other horizontal joints 5. Therefore, the joint strength in the overlapping region 5a where the horizontal joints 5 and the vertical joints 6 overlap is likely to be weaker than the joint strength in the region where the horizontal joints 5 do not overlap with the vertical joint 6. Therefore, in a preferred embodiment, the joint strength in the overlapping region 5a is made relatively weak.

[0076] Such overlapping regions 5a have a relatively weak bonding strength and therefore tend to become opening starting points when opening the packaging bag 4 of the packaged product 2. This makes it possible to make the packaging bag 4 easier to open during use while suppressing evaporation of the volatile functional agent in the absorbent article 3. In this case, the sound generated when opening the packaging bag 4 can be reduced, making it difficult for people around to notice and reducing the user's sense of embarrassment.

[0077] The method for measuring the bonding strength is as follows: Fig. 6 is a diagram for explaining the method for measuring the bonding strength of the packaged product according to the embodiment. (1) In the package 2, a portion including only the horizontal joint 5 shown in Fig. 6(a) is cut out with a sharp blade (e.g., a cutter knife) to a size of width dm1 (25 mm) × length dm2 (40 mm) to give a sample MS1. Similarly, a portion including both the vertical joint 6 and the horizontal joint 5 shown in Fig. 6(a) is cut out with a sharp blade (e.g., a cutter knife) to a size of width dm1 (25 mm) × length dm2 (40 mm) to give a sample MS2. (2) For each of the samples MS1 and MS2, clear tape T1 is attached to both sides of one end in the length direction, so that one end of the clear tape T1 is joined to each of the samples MS1 and MS2 and becomes a fixed end, and the other end is a free end that is not joined to anything. (3) For each of samples MS1 and MS2, the free end of clear tape T1 attached to one side of the longitudinal end and the free end of clear tape T1 attached to the other side are each clamped in the chucks (chuck distance 10 mm) of a tensile testing machine (Shimadzu Corporation, Autograph, model AGS-1kNG). (4) Using a tensile testing machine, the free end of clear tape T1 attached to one side of the longitudinal end and the free end of clear tape T1 attached to the other side are pulled away from each other in a 180° direction (indicated by arrow "F" in the figure), and the load value is measured. (5) The maximum load value measured is the joint strength (N / 25 mm).

[0078] In a preferred embodiment of this embodiment, each of the pair of horizontal joints 5 has a plurality of continuous patterns extending along the second direction and spaced apart in the first direction. In the example of FIG. 5, three thin line-shaped heat fusion patterns extending along the second direction and spaced apart in the first direction are formed as the horizontal joints 5. Each thin line pattern has a width of, for example, 0.5 to 1.5 mm, preferably 0.7 to 1.3 mm. The interval between the thin line patterns may be, for example, 0.3 to 1.3 mm, preferably 0.5 to 1.1 mm.

[0079] In this way, the horizontal joint 5 includes a plurality of continuous patterns extending along the second direction and arranged at intervals in the first direction, thereby improving the sealability of the packaging bag 4. Furthermore, even if a part of the plurality of continuous patterns in the horizontal joint 5 comes off during the manufacture or sale of the linked packaged product 1, the remaining part of the plurality of continuous patterns remains, thereby maintaining the sealability. In particular, when one of the ends of the plurality of linked packaged products 2 in the linked packaged product 1 is cut between the horizontal joints 5, the sealability at the horizontal joints 5 is easily maintained. This makes it possible to suppress the evaporation of a volatile functional agent in the absorbent article 3.

[0080] Furthermore, by including a continuous pattern of multiple lines spaced apart in the first direction, the horizontal joint 5 can make it easier to open the packaging bag 4 of the packaged product 2 compared to a case in which the horizontal joint 5 includes a single continuous pattern made up of multiple lines. This makes it easier to open the packaging bag 4 during use while suppressing evaporation of the volatile functional agent in the absorbent article 3. In this case, the sound made when the packaging bag 4 is opened can be reduced, making it less likely to be noticed by people around and less likely to embarrass the user.

[0081] In a preferred embodiment of the present invention, in each of the multiple packaged products 2, the absorbent articles 3 in the packaging bag 4 are contained in an individual packaging bag 21. The individual packaging bag 21 is located at both ends in the second direction (width direction W) and includes a pair of individual packaging horizontal joints 22 that seal both ends of the individual packaging bag 21. The distance between both end edges in the second direction of the packaging bag 4 (= length d2) is less than the distance between the outer end edges in the second direction of the pair of individual packaging horizontal joints 22 (= length d1).

[0082] In the linked packaged product 1, as shown in Fig. 5, the distance (width = length d2) between both end edges in the second direction (width direction W) of the packaging bag 4 is smaller than the distance (= length d1) between the outer end edges in the second direction of the pair of individual package horizontal joints 22. Therefore, the individual package bag 21 containing the absorbent article 3 is sealed in the packaging bag 4 with each of the pair of individual package horizontal joints 22 located at both ends in the second direction folded inward. Therefore, even after the packaging bag 4 is opened, the volatile functional agent is unlikely to evaporate from each of the pair of individual package horizontal joints 22. Therefore, the functional agent is likely to remain in the absorbent article 3 not only before but also after the packaging bag 4 is opened, so that the function of the functional agent is likely to be fully obtained.

[0083] The linked packaged product of the present invention is not limited to the above-described embodiments, and appropriate combinations and modifications of the techniques described in the embodiments and known techniques are possible within the scope of the purpose and intent of the present invention.
