Description:
TECHNICAL FIELD  
       [0001]    The present invention relates to a package structure configured of an absorbent article and a package sheet for packaging the absorbent article individually. 
       BACKGROUND ART  
       [0002]    Conventionally, there is known a package structure configured of an absorbent article and a package sheet for packaging the absorbent article individually (for example, see Patent Literatures 1 and 2). 
         [0003]    For example, in the package structure described in Patent Literature 1, when the package sheet is opened, adhesives used for the absorbent article to attach to underwear are all exposed. 
         [0004]    Further, in the package structure described in Patent Literature 2, when the package sheet is opened, adhesives used for the absorbent article arranged in wing portions and hip flap portions which configure the absorbent article to attach to underwear remain covered by a non-hydrolyzable release sheet and are not exposed.

       SUMMARY OF INVENTION  
       [0007]    However, the applicants faced the following problem as regards the above package structure. 
         [0008]    In the package structure described in Patent Literature 1, the adhesives used for the absorbent article to attach to underwear are all exposed when the package sheet is opened, so that when the absorbent article is attached to underwear, the adhesives arranged in the hip flap portions are adhered to each other or the adhesives arranged in the wing portions are adhered to the absorbent article body due to a folding pattern given to the hip flap portions at the time of individual packaging, thereby leading to a problem that the absorbent article cannot be attached to underwear finely, which possibly causes the leakage or twist. 
         [0009]    Further, in the package structure described in Patent Literature 2, the release sheet is divided from the package sheet, so that the adhesives used for the absorbent article to attach to underwear are not all exposed in a case where the package sheet is opened. However, this leads to a problem that multiple pieces of trash which cannot be flushed down the toilet are generated, which causes trouble in dealing with this trash. 
         [0010]    Thus, the present invention has been achieved in view of the aforementioned problem, and an object thereof is to provide a package structure which is, when opening the package sheet, capable of preventing exposure of all the adhesives used for the absorbent article to attach to underwear while reducing generation of trash which cannot be flushed down the toilet. 
         [0011]    A first feature of the present invention is summarized as a package structure comprising: an absorbent article; and a package sheet that packages the absorbent article individually, wherein: the absorbent article comprising: a liquid-permeable topsheet; a liquid-impermeable backsheet; and an absorber arranged between the topsheet and the backsheet; the absorbent article is provided with a wing portion protruded outwardly in a width direction; a first portion at a clothing contact surface side of the wing portion and a second portion at the clothing contact surface side of the backsheet are coated with an adhesive for fixing the absorbent article to underwear; a hydrolyzable release sheet is provided that covers the first portion in a state where the wing portion is folded back toward a skin contact surface side of the topsheet; and the package sheet is non-hydrolyzable, is releasable with respect to the adhesive for fixing to the underwear, and is provided that covers the second portion.

         [0037]    As shown in  FIG. 5 , a hydrolyzable release sheet  21   a  is provided so as to cover the first portions  51  in a state where the wing portions  41  are folded back toward the skin contact surface side of the topsheet  11 . 
         [0038]    Similarly, a hydrolyzable release sheet  21   b  is provided so as to cover the portions  52  in a state where the hip flap portions  42  are folded back toward the skin contact surface side of the topsheet  11 . 
         [0039]    The release sheets for covering the first portions  51  and portions  52  are provided not integrally but independently, which requires less material to thereby achieve reduction in costs as well as improvement in hydrolyzability of the release sheets. 
         [0040]    Herein, a material which can be used as the release sheets  21   a ,  21   b  is such as obtained by coating a surface of base paper of 36 g/m 2  (for example, 0.8 to 1.1 g/m 3 ) made of pulp fibers with polyvinyle alcohol (PVA) of 1.0 to 2.0 g/m 3  and further coating it over with silicone of 0.3 to 0.8 g/m 3 . 
         [0041]    It is preferable that the hydrolyzable release sheets  21   a ,  21   b  be dispersed into three or more pieces within 24 hours by a shake-flask test to be described later. 
         [0042]    Specifically, such a shake-flask test is carried out as described below. 
         [0043]    In this shake-flask test, the release sheets  21   a ,  21   b  of 100 mm×100 mm are used as a sample. Further, used in this shake-flask test are a shaking apparatus (such as a separatory funnel shaker manufactured by Asahi Techno Glass Corporation, Iwaki Glass Co., Ltd.), an eggplant shaped flask for 1000 mL, a measuring cylinder of 1000 mL, and the like. 
         [0044]    Firstly, distilled water of 800 mL is poured into the eggplant shaped flask by using the measuring cylinder. 
         [0045]    Secondly, the sample is put into the eggplant shaped flask. 
         [0046]    Thirdly, the eggplant shaped flask is attached to the shaking apparatus. Herein, a screw-on lid side of the eggplant shaped flask is facing the bottom and a cock side of the eggplant shaped flask is facing the top. 
         [0047]    Fourthly, a shaking condition (shaking speed: 240 rpm, shaking time: 24 hours) is set. 
         [0048]    It is to be noted that in the present embodiment, the hydrolyzable release sheets  21   a ,  21   b  include water-soluble release sheets  21   a ,  21   b.    
         [0049]    For example, as the aforementioned water-soluble release sheets  21   a ,  21   b , a material such as a film configured by water-soluble resin such as PVA, a material obtained by coating a nonwoven cloth with silicone, and the like can be used. 
         [0050]    Further, as shown in  FIGS. 6 and 7 , the package sheet  2  is releasable and also provided so as to cover the second portions  50 . 
         [0051]    Herein, a polyethylene sheet, a polypropylene sheet, a polyurethane sheet, and the like can be used as the package sheet  2 , and polypropylene long-fibered nonwoven cloth laminated body with a spun bonding/melt-blowing/spun bonding structure can be used. 
         [0052]    In the package structure  100  according to the present embodiment, as shown in  FIG. 7 , a non-hydrolyzable release sheet  22  as an independent body may be bonded to the package sheet  2  with an adhesive coated to a portion  60  at a side in which the absorbent article  1  is arranged. 
         [0053]    In such a case, the release sheet  22  is provided so as to cover the second portions  50  at the clothing contact surface side of the backsheet  12 . 
         [0054]    Further, in the package structure  100  according to the present embodiment, a portion subjected to a release coating process using a release agent such as silicon resin or fluororesin system may be formed in at least one part of the package sheet  2 . 
         [0055]    Herein, at least one of different texts and patterns is inserted in the hydrolyzable release sheets  21   a ,  21   b  and the non-hydrolyzable release sheet  22  by means of printing, embossing, or the like. 
         [0056]    For example, as shown in  FIG. 5 , at least one of texts and patterns indicative of a toilet flushable status, is inserted in the hydrolyzable release sheets  21   a ,  21   b  by means of printing, embossing, or the like. 
         [0057]    Such an insertion is visually recognizable from the skin contact surface side of the hydrolyzable release sheets  21   a ,  21   b  in a state where the package structure  100  is opened. 
         [0058]    Further, as shown in  FIG. 6 , at least one of a text and a pattern indicative of a toilet non-flushable status may be inserted in the non-hydrolyzable release sheet  22  by means of printing, embossing, or the like. 
         [0059]    Such an insertion may be visually recognizable from a release surface side of the release sheet  22  in a state where the package structure  100  is opened and the package sheet  2  is released from the absorbent article  1 . Further, such an insertion may be visually recognizable from the outside of the package structure  100  in a state where the absorbent article  1  is packaged individually. 
         [0060]    Herein, at least one of a text and a pattern indicative of a toilet non-flushable status may be inserted in the package sheet  2  by means of printing, embossing, or the like. 
         [0061]    Such an insertion may be visually recognizable from a release surface side of the package sheet  2  in a state where the package structure  100  is opened and the package sheet  2  is released from the absorbent article  1 . Further, such an insertion may be visually recognizable from the outside of the package structure  100  in a state where the absorbent article  1  is packaged individually. 
         [0062]    Further, the package structure  100  according to the present invention is configured so as to package the absorbent article  1  individually by folding the package sheet  2  along a first folding line X 1 , a second folding line X 2 , and a third folding line X 3 , as shown in  FIGS. 5 and 6 . 
         [0063]    Herein, as shown in  FIG. 5 , the hydrolyzable release sheet  21   a  may be arranged so as not to cross the first folding line X 1 , the second folding line X 2 , and the third folding line X 3  in the longitudinal direction L. 
         [0064]    According to such a configuration, there is an improvement in visibility of a text or pattern inserted in the hydrolyzable release sheet  21   a  at the time of opening the package structure  100 . 
         [0065]    It is to be noted that the hydrolyzable release sheet  21   b  may also be arranged so as not to cross the first folding line X 1 , the second folding line X 2 , and the third folding line X 3  in the longitudinal direction L (see  FIG. 10  to be described in details later). 
         [0066]    As shown in  FIG. 7 , the absorbent article  1  configuring the package structure  100  according to the present embodiment has the liquid-permeable topsheet  11 , the liquid-impermeable backsheet  12 , and the absorber  13  arranged between the topsheet  11  and the backsheet  12 . It is to be noted that the absorbent article  1  according to the present embodiment may have a second sheet between the topsheet  11  and the absorber  13 . 
         [0067]    For example, as the topsheet  11 , a fiber as an air-through nonwoven cloth with basis weight of  25 , formed of a core with a thickness of 2.2 dtex made of polyethylene terephthalate (PET) and a clad made of polyethylene (PE) may be used. 
         [0068]    Herein, a density of the topsheet  11  may be adjusted to be 0.025 g/cm 3  by treating the topsheet  11  with a bulk recovery process (in which, for example, the topsheet  11  is left at a temperature of 90 degrees for 10 minutes). 
         [0069]    The absorber  13  is configured by ground pulp, a superabsorbent polymer, and a core wrap for wrapping both. Herein, a macromolecular polymer is a granular polymer of a sodium acrylate copolymer. 
         [0070]    Further, the core wrap is a sheet made from an arbitrary material which absorbs liquid. For example, as the core wrap, a tissue may be used, or an air-laid sheet formed by shaping a hydrophilic fiber or ground pulp into a sheet by an air-laid method may be used. 
         [0071]    Described with reference to  FIGS. 8(   a ) to  8 ( d ) is a movement of the user to use the absorbent article  1  included in the package structure  100  by opening the package structure  100  according to the present embodiment. 
         [0072]    Firstly, the user removes a used absorbent article  1  fixed to underwear. 
         [0073]    Secondly, as shown in  FIG. 8(   b ), the user opens the package structure  100  in a state shown in  FIG. 8(   a ). 
         [0074]    Thirdly, as shown in  FIG. 8(   c ), the user releases the package sheet  2  from the absorbent article  1 . 
         [0075]    Then the user wraps the used absorbent article  1  in the released package sheet  2  and carries it back or throws it into a trash box. 
         [0076]    Further, in this absorbent article  1  in the state described above, the adhesives coated to the second portions  50  at the clothing contact surface side of the backsheet  12  are exposed whereas the adhesives coated to the first portions  51  at the clothing contact surface side of the wing portions  41  and the portions  52  at the clothing contact surface side of the hip flap portions  42  are not exposed. 
         [0077]    Fourthly, the user attaches this absorbent article  1  to underwear. 
         [0078]    Subsequently, as shown in  FIG. 8(   d ), the user releases the hydrolyzable release sheet  21   a  from the absorbent article  1  and wraps the wing portions  41  around a crotch of the underwear to fix them. Herein, the user discards the released hydrolyzable release sheet  21   a  in a toilet. 
         [0079]    Similarly, as shown in  FIG. 8(   d ), the user releases the hydrolyzable release sheet  21   b  from the absorbent article  1  and spreads the hip flap portions  42  on underwear to fix them. Herein, the user discards the released hydrolyzable release sheet  21   a  in a toilet. 
         [0080]    Next, some of methods of manufacturing the package structure  100  according to the present embodiment are described. It is to be noted that as far as the methods that are not described in below are concerned, the existing methods can be used. 
         [0081]    Firstly, the absorbent article  1  is cut out of a web being conveyed. 
         [0082]    Secondly, the wing portions  41  and the hip flap portions  42  are folded back toward the skin contact surface side of the absorbent article  1 . 
         [0083]    Thirdly, the release sheets  21   a ,  21   b  are coated with adhesives and arranged so as to cover the first portions  51  in the folded wing portions  41  and the portions  52  in the hip flap portions  42 . 
         [0084]    Fourthly, the absorbent article  1  is arranged on a web for the package sheet  2  in a state where the clothing contact surface side is facing the bottom. 
         [0085]    Fifthly, a folding step is performed in a state where the absorbent article  1  is arranged on the web for the package sheet  2 . 
         [0086]    According to the package structure  100  in the present embodiment, the release sheets  21   a ,  21   b  are provided so as to cover the first portions  51  and the portions  52  in a state where the wing portions  41  are folded back toward the skin contact surface side of the topsheet  11  while the package sheet  2  and the release sheet  22  are provided so as to cover the second portions  50 , so that the adhesives for attaching the absorbent article  1  to underwear can be prevented from being all exposed at the time of opening. 
         [0087]    Further, according to the package structure  100  in the present invention, the non-hydrolyzable package sheet  2  and the release sheet  22  are bonded together, thereby being able to avoid such a situation that multiple pieces of trash which cannot be flushed down the toilet are generated at the time of opening. 
         [0088]    Further, the package structure  100  according to the present embodiment enables the adhesives, which are arranged in the first portions  51  at the clothing contact surface side of the wing portions  41 , to be exposed after the package sheet  2  is opened and then the adhesives arranged in the second portions  50  at the clothing contact surface side of the backsheet  12  are adhered to underwear, while enabling the release sheets  21   a ,  21   b , which cover the adhesives arranged in the wing portions  41  and the hip flap portions  42 , to be flushed down the toilet after the used absorbent article  1  is wrapped in the package sheet  2  and discarded. 
         [0089]    Further, according to the package structure  100  in the present embodiment, at least one of different texts and patterns is inserted in the hydrolyzable release sheets  21   a ,  21   b  and the non-hydrolyzable release sheet  22 . Specifically, in a case where at least one of texts and patterns indicative of a toilet flushable status is inserted in the hydrolyzable release sheets  21   a ,  21   b  while at least one of a text and a pattern indicative of a toilet non-flushable status is inserted in the non-hydrolyzable release sheet  22 , the user can distinguish between the release sheets  21   a ,  21   b  which can be flushed down the toilet and the release sheet  22  which cannot be flushed down the toilet. 
       First Modification 
       [0090]    With reference to  FIG. 9 , the package structure  100  according to a first modification of the present invention will be described while focusing on the differences from the absorbent article  100  according to the aforementioned first embodiment. 
         [0091]    In the package structure  100  according to this first modification, as shown in  FIG. 9 , in place of the hydrolyzable release sheets  21   a ,  21   b , a pair of hydrolyzable release sheets  23  is provided so as to cover the portions  51  and the portions  52 . 
       Second Modification 
       [0092]    With reference to  FIGS. 10 and 11 , the package structure  100  according to a second modification of the present invention will be described while focusing on the differences from the absorbent article  100  according to the aforementioned first embodiment. 
         [0093]    In the package structure  100  according to this second modification, as shown in  FIGS. 10 and 11 , an adhesive is coated to a portion  21   d  at a surface side not subjected to a release coating process, of a non-hydrolyzable release sheet  21   c , in which the portion  21   d  comes in contact with the package sheet  2  in a state where the absorbent article  1  is packaged individually, and the release sheet  21   c  is provided so as to cover the portions  51   
         [0094]    According to such a configuration, the non-hydrolyzable release sheet  21   c  is bonded to the package sheet  2  with the absorbent article  1  being packaged individually, thereby being released from the absorbent article  1  at the time of opening the package sheet  2  along the third folding line X 3 , which saves the user time and effort of releasing the non-hydrolyzable release sheet  21   c  from the absorbent article  1 . 
       Other Modifications 
       [0095]    It is to be noted that the hydrolyzable release sheets  21   a ,  21   b  and the non-hydrolyzable release sheet  22  may be configured of materials with different hues. 
         [0096]    According to such a configuration, the user can distinguish between the release sheets  21   a ,  21   b  which can be flushed down the toilet and the release sheet  22  which cannot be flushed down the toilet. 
         [0097]    It is to be noted that the hydrolyzable release sheets  21   a ,  21   b  and the non-hydrolyzable release sheet  22  may be given different hues by printing or by dyeing. In a case of giving different hues to the hydrolyzable release sheets  21   a ,  21   b  and the non-hydrolyzable release sheet  22  by dyeing, no ink is placed between fibers, thereby being able to maintain hydrolyzability of the release sheets  21   a ,  21   b.    
         [0098]    Further, the hydrolyzable release sheets  21   a ,  21   b  may be provided with a portion subjected to the release coating process and a portion not subjected to the release coating process. 
         [0099]    For example, within the hydrolyzable release sheets  21   a ,  21   b , a portion which comes in contact with the portions  51 ,  52  may be subjected to the release coating process and the other portion may not be subjected to the release coating process. 
         [0100]    According to such a configuration, the portion not subjected to the release coating process is prone to get wet with water, thereby achieving improvement in hydrolyzability. 
         [0101]    Further, the hydrolyzable sheets  21   a ,  21   b  may be formed by performing a release coating process to a crepe paper. According to such a configuration, its wave shape increases a surface area which comes in contact with water, thereby achieving improvement in hydrolyzability. 
         [0102]    Further, the hydrolyzable sheets  21   a ,  21   b  may be provided with a plurality of slits or a stretch-processed region. According to such a configuration, it becomes easier for the hydrolyzable sheets  21   a ,  21   b  to be divided by water flow, thereby achieving improvement in hydrolyzability. 
         [0103]    Further, the hydrolyzable sheets  21   a ,  21   b  may have a shape configured to reduce a resistance to water flow. For example, the hydrolyzable sheets  21   a ,  21   b  may have a shape having a convex portion in such as an arrowhead shape, as a shape to reduce a resistance to water flow. 
         [0104]    According to such a configuration, it becomes easier for the hydrolyzable sheets  21   a ,  21   b  to sink under water, that is, to float away in water. 
         [0105]    Further, the hydrolyzable sheets  21   a ,  21   b  may be coated with hydrophilic oil solution. 
         [0106]    According to such a configuration, the hydrolyzable sheets  21   a ,  21   b  can be further improved in its hydrolyzability while making it easier for them to sink under water, that is, to float away in water. 
         [0107]    It is to be noted that the absorbent article  1  included in the package structure  100  may not be provided with the wing portions  41 . In such a case, the user fixes the absorbent article  1  to underwear by adjusting a position in which the absorbent article  1  has the shortest length in the width direction W, to a crotch of underwear at the time of wearing the absorbent article  1  to underwear. 
         [0108]    Further, in consideration of attachability of the absorbent article  1  with respect to underwear, a length in the width direction W of the release sheets  21   a ,  21   b ,  22  may be shorter than a length in the width direction W of the absorber article  1 . 
         [0109]    Thus, the present invention has been explained in detail by using the above-described embodiments; however, it is obvious that for persons skilled in the art, the present invention is not limited to the embodiments explained herein. The present invention can be implemented as corrected and modified modes without departing from the gist and the scope of the present invention defined by the claims. Therefore, the description of the specification is intended for explaining the example only and does not impose any limited meaning to the present invention. 
         [0110]    In addition, the entire content of Japanese Patent Application No. 2010-148362 (filed on Jun. 29, 2010) is incorporated in the present specification by reference. 
       INDUSTRIAL APPLICABILITY
