Description

  The present invention relates to an individual package of absorbent articles.

  Conventionally, absorbent articles such as sanitary napkins and panty liners (orimono sheets) are commercially available as products, such as sanitary napkins and panty liners, which are folded together with a packaging material, individually wrapped, and enclosed in an interior pack. In particular, sanitary products may be taken out of the interior pack and placed in a pouch or the like.

Patent Document 1 discloses an absorbent article that is housed in a folded state when not in use, and that is unfolded and locked to an adherend when used. This absorbent article is in contact with the adhesive area for locking the absorbent article to the adherend on the outer surface area, and another adjacent absorbent article or the adhesive area of the same absorbent article when not in use. And a release region. The adhesive region includes an adhesive part having an adhesive surface that can be attached to and detached from the adherend, and a plurality of protrusions protruding from the adhesive surface. The release region is composed of an outer surface region that has not been subjected to a special release process.
Moreover, the adhesion area | region and the mold release area | region are formed in the longitudinal direction both ends vicinity of an absorbent article. When the absorbent article is not in use, the absorbent article is folded so that the both ends where the release area is formed are folded toward the inner center, and the adhesive area at one end and the release area at the other end in the same article are in contact with each other. Is folded in four.

Patent Document 2 has a pair of left and right first wing portions in front of the main body and a pair of left and right second wing portions in the rear of the main body, and a main body adhesive portion is provided on the non-skin contact surface side of the main body. It consists of an absorbent article in which a first wing adhesive part and a second wing adhesive part are provided on the non-skin contact surface side of the first and second wing parts, respectively, and a packaging sheet for individually mounting the absorbent article. A packaging structure of an absorbent article is disclosed in which the absorbent article and the packaging sheet are folded together by adhering the part and the inner surface of the packaging sheet in a peelable manner. The first and second wing portions are each bent toward the skin contact surface side of the main body. Both the 1st and 2nd wing adhesion parts are stuck to the adhesion part protection sheet so that peeling is possible. The protective sheet has an extending part that extends to the front edge side rather than the first or second wing adhesive part located on the front edge side of the packaging sheet. The extending part has a fixing part for fixing the adhesive part protective sheet to the outer surface of the packaging sheet or the inner surface of the packaging sheet extended outward from the rear end of the absorbent article.

JP 2003-159268 A Japanese Patent Laid-Open No. 2000-083991

The absorbent article disclosed in Patent Document 1 described above is characterized in that it does not use a release paper (protective film) that is peeled off at the time of use, and at the time of mounting and during mounting without using another member such as a release paper. It is said that the optimum engagement force is exhibited in However, even if the absorbent article is folded before use, it is not suitable for portable use because it is difficult to carry hygienically. In addition, there is a disadvantage that it is not possible to secure a wide stop surface.
Moreover, the packaging structure of the absorbent article disclosed in Patent Document 1 described above is considered to be easy to take out without the adhesive portions adhering to each other. However, when the product body is taken out, the packaging sheet with the protective sheet is long and large.

  In some cases, sanitary products are taken out from an interior pack in which a plurality of sanitary products are packaged, and individually put in a pouch or the like. When carrying, there is a need to keep the product clean, with no dust in the individually packaged sanitary products. Furthermore, the individual packaging materials to be discarded are required to be compact and easy to discard. In addition, since the normal packaging material is folded in order from the rear end to the front end together with the product, and the opening portion is the end portion of the packaging material and the product, in the individual packaging body of a thin absorbent article, When the packaging material is opened for the first time, it may be difficult to open it because it is too thin. Therefore, a packaging form that is easy to open is required. In order to solve the problem that it is difficult to open, many products are provided with a tab using a tab tape. However, the adhesive strength of the tape is too strong and the packaging material is torn and difficult to open, and when it is discarded, the torn packaging material adheres to the tape, and the used napkin is wrapped with the packaging material and rolled up. The problem is that it is hard to throw away.

  The present invention is an individual packaging body for a thin absorbent article, in which dust does not enter the sanitary product individually packaged, and the inside of the sanitary product is kept clean when the sanitary product individually packaged is carried. The present invention also relates to providing an individual package of an absorbent article that is easy to open and easy to dispose of.

  The present invention is an individual packaging body of an absorbent article in which an absorbent article having a skin contact surface and a non-skin contact surface on the opposite surface is individually packaged together with a packaging material provided on the non-skin contact surface side. The packaging material has a front fold line, a center fold line, and a rear fold line, and is divided into a front part, a center front part, a center rear part, and a rear part by the fold lines, and the absorbent article is disposed in a state where the absorbent article is arranged. The packaging material is folded in four in the longitudinal direction, and the front folding line is folded so that the surfaces on which the absorbent articles of the front part and the central front part are arranged face each other, and the rear Folded lines are folded so that the surfaces on which the absorbent articles of the rear part and the central rear part are arranged face each other, and the absorbent article has a skin contact surface on the inside of the individual package. Folded at least at the central fold line so that the front fold line and the back fold line overlap Instead, at least one of the front part and the rear part of the packaging material is provided with an individual packaging body for absorbent articles provided with a packaging stabilization means in a region where the front part and the rear part are opposed to each other. To do.

  The individual packaging body of the absorbent article of the present invention can keep the product clean without carrying dust in the individually packaged sanitary goods when carrying the individually packaged sanitary goods. Even individual packages are easy to open.

It is the expanded view which showed an example of the individual packaging body of another absorptive article concerning a 2nd embodiment in the state where a part of packaging material was folded. It is the partial expansion | deployment top view which showed another example of the individual packaging body of the absorbent article which concerns on each embodiment. It is the partial fracture | rupture perspective view which showed an example of the sanitary napkin as an absorbent article used for each embodiment.

  A preferred embodiment (first embodiment) of an individual package of absorbent articles according to the present invention will be described below with reference to FIG. In the present specification, “front” refers to the lower abdomen direction when the absorbent article is worn, and “rear” refers to the buttocks direction when the absorbent article is worn. Moreover, the skin contact surface at the time of wearing means the surface which contacts the skin side at the time of wear, and the other side is called a non-skin contact surface. Furthermore, the side close to the skin contact surface is referred to as the skin contact surface side or surface side, and the far side is referred to as the non-skin contact surface or back surface side.

  As shown in FIG. 1, an absorbent article having a skin contact surface and a non-skin contact surface opposite to the skin contact surface, which is wrapped in the individual package 20 (20 a) of the present embodiment, is called a slim type, for example. This is a thin sanitary napkin 10. Hereinafter, the individual packaging body of a thin sanitary napkin will be described in detail.

The individual package 20 of the absorbent article is formed by folding the packaging material 30 together with the sanitary napkin 10 in the longitudinal direction and sealing the packaging material 30.
The individual wrapping body 20 has a front folding line L1, a central folding line L2, and a rear folding line L3, and is divided into a front part 21, a central front part 22, a central rear part 23, and a rear part 24 by each folding line, and the sanitary napkin 10 is folded in four in the longitudinal direction in a state where 10 is adhered to the packaging material 30 so as to be peelable by the main body displacement stopper 9. In this example, the sanitary napkin 10 is longer than the packaging material 30 in the longitudinal direction, and the sanitary napkin 10 is shorter than the packaging material 30 in the width direction. In other words, the front and rear ends of the packaging material 30 are positioned on the inner side of the longitudinal front edge and the rear edge of the sanitary napkin 10 as the absorbent article in the longitudinal direction. On the other hand, in this example, the sanitary napkin 10 exists corresponding to each part of the front part 21, the center front part 22, the center rear part 23, and the rear part 24 of the packaging material 30. In this specification, the surface on which the sanitary napkin 10 is disposed on the packaging material 30 is the surface of the packaging material 30, and the opposite surface is the back surface of the packaging material 30.

  Wings 5 are arranged on both sides of the central front portion 22 of the sanitary napkin 10, and each wing 5 comes into contact with the skin of the main body 4 from the boundary base end position of the main body 4 and the wing 5 of the sanitary napkin 10. It is folded to the surface side. The sanitary napkin 10 has a configuration in which an upper layer absorbent body 3a is disposed on a lower layer absorbent body (not shown) at the center in the article width direction as indicated by a dotted line in the central front portion 22. In this configuration, the wing 5 is folded so as not to overlap the upper-layer absorber 3a. Hip guards 6 are arranged on both sides of the sanitary napkin 10 from the central rear part 22 to the rear part 23, and each hip guard 6 is located from the boundary base end position between the body 4 of the sanitary napkin 10 and the hip guard 6. The main body 4 is folded to the skin contact surface side. In addition, the wing 5 is an overhang | projection part extended and formed in both right-and-left sides on both sides of the excretion part use | placement and the absorber 3 (refer FIG. 4 mentioned later), and the hip guard 6 is located in the back of the wing 5. And it is an overhang | projection part distribute | arranged to a wearer's buttocks position formed in both right and left sides on both sides of the absorber 3. FIG.

  An adhesive portion 7 is disposed on the non-skin contact surface side of the wing 5. The adhesive portion 7 is for fixing the sanitary napkin 10 to the non-skin contact surface side of the shorts when the wing 5 is folded and the sanitary napkin 10 is attached to the shorts (not shown). Similarly, the adhesive part 8 is arranged on the non-skin contact surface side of the hip guard 6. The adhesive portion 8 is for fixing the sanitary napkin 10 to the shorts when the hip guard 6 is folded and the sanitary napkin 10 is attached to the shorts (not shown).

  The packaging material 30 is folded together with the sanitary napkin 10 so that the front fold line L1 faces the sanitary napkins 10 of the front part 21 and the central front part 22 facing each other. A release sheet 11 is arranged on the skin contact surface side of the sanitary napkin 10 located in the front part 21 so as to be peelably bonded to the adhesive part 7. A part of the release sheet 11 may be arranged so as to cover the central front part 22. Further, the release sheet 11 is disposed and fixed on the back surface side of the packaging material 30 so as to go around the end portion of the front portion 21 in the longitudinal direction from the skin contact surface side of the sanitary napkin 10. Further, the release sheet 11 extends in the direction of the front fold line L <b> 1 from the fixing portion 12 where the release sheet 11 is fixed to the packaging material 30. Therefore, since the end 11e of the extended part of the release sheet 11 is a free end, it can be easily picked with a finger.

The rear folding line L3 is folded so that the surfaces on which the sanitary napkins 10 of the central rear portion 23 and the rear portion 24 are arranged face each other. In the case of this example, the sanitary napkin 10 is folded so that the skin contact surfaces of the sanitary napkin 10 of the front part 21 and the center front part 22 face each other at the front fold line L1. A release sheet 13 is arranged on the skin contact surface side of the sanitary napkin 10 located in the rear part 24 so that the adhesive part 8 of the hip guard 6 can be peeled off when folded. Further, the release sheet 13 is disposed and fixed on the back side of the packaging material 30 around the end of the rear portion 24 from the skin contact surface side of the sanitary napkin 10.
As described above, the release sheets 11 and 13 are arranged separately. For this reason, since the length of each peeling sheet 11 and 13 after peeling is short, it becomes easy to handle and the effect that the garbage at the time of disposal decreases is acquired.

  The packaging material 30 is folded together with the sanitary napkin 10 and the release sheets 11 and 13 so that the front fold line L1 faces the sanitary napkins 10 of the front part 21 and the central front part 22 facing each other. Folded and folded so that the surfaces on which the sanitary napkins 10 of the central rear portion 23 and the rear portion 24 are arranged face each other at the rear folding line L3. At that time, when the release sheet is applied to the fold line, the release sheet is also folded at the fold line. In this example, the sanitary napkin 10 of the front part 21 and the center front part 22 are folded so that the skin contact surfaces of the front part 21 and the center front part 22 face each other via the release sheet 11 at the front fold line L1, and the center rear part at the rear fold line L3. The skin contact surfaces of the sanitary napkins 10 of the sanitary napkin 23 and the rear portion 24 are folded so as to face each other with the release sheet 13 therebetween. Further, the sanitary napkin 10 is folded at least at the center fold line L2 so that the skin contact surface is inside the individual package 20, and the non-skin contact surface of the front portion 21 and the non-skin contact of the rear portion 24 are provided. The tangent faces are opposite.

In the specification in which the release sheet 13 disposed on the back surface side of the packaging material 30 is not fixed to the packaging material 30, the length required for 13 is shortened, and dust can be reduced.
When the release sheets 11 and 13 are not arranged on the back side of the packaging material 30, the packaging material 30 is extended longer than the sanitary napkin 10, and the wing 5 and the hip guard 6 are adhered to the front side of the sanitary napkin 10. It may be a specification in which a separate release paper (not shown) arranged to cover the portions 7 and 8 and a release sheet such as a release film are adhered. When bonding the release paper, the extended portion of the packaging material 30 can be used as an unpeeled portion, and the tip of the release paper can be folded, or the unpeeled portion can be provided and fixed with an adhesive in the same manner as the packaging material 30. . In the case of a release film, both the packaging material 30 and the release film can be bonded and fixed by heat sealing or the like without providing an unpeeled portion.

The front folding line L1 and the rear folding line L3 do not overlap in the individual packaging state, but are arranged at positions shifted from each other (see FIG. 1B). Thereby, the part including one broken line position functions as a knob for opening. As for the shifting method, the front folding line L1 may be outside and the rear folding line L3 may be inside, and conversely, the front folding line L1 may be inside and the rear folding line L3 may be outside.
Further, the amount of shift between the front fold line L1 and the rear fold line L3 (distance between L1 and L3, see FIG. 1B) is 3 mm or more, preferably 5 mm or more, more preferably 7 mm or more. And the shift amount of the front folding line L1 and the rear folding line L3 is 25 mm or less, Preferably it is 20 mm or less, More preferably, it is 15 mm or less. More specifically, the thickness is 3 mm to 25 mm, preferably 5 mm to 20 mm, and more preferably 7 mm to 15 mm. By setting it as the said range, even if the sanitary napkin 10 is a thin thing like a slim type, since it becomes easy to pinch the broken line part distribute | arranged outside, it becomes easy to open the individual package 20. If the amount of shifting is too short, it becomes difficult to pick the broken line portion arranged on the outside, and it becomes difficult to open the individual package 20.

  About the shift | offset | difference position of the front fold line L1 and the back fold line L3, as shown in FIG.1 (b), it is preferable that it is arranged so that it may protrude from the back fold line L3 so that the front fold line L1 may become a knob. By pinching the front fold line L1 with the fingertips and opening the rear fold line L3 while pulling, the front part 21 of the product is pinched, so that the sanitary napkin 10 can be worn without mistakes at the time of wearing. If the front part 21 of the product of the sanitary napkin 10 is folded along the front fold line L1, the rear part 24 of the product can be opened while reducing the chance that the fingertip directly touches the use surface even if it is pinched. Here, the “product” means one that is folded and individually wrapped, one that is being opened individually, or one that is opened and folded.

A packaging stabilizing means 40 is disposed on at least one of the back surface of the packaging material 30 in the front portion 21 and the back surface of the packaging material 30 in the rear portion 24.
For the packaging stabilizing means 40, an adhesive material, a mechanical fastener, a friction increasing means by embossing, or the like is used. An example of the adhesive material is a hot melt adhesive. By using a hot melt adhesive, the sealing performance is further increased.

One of the installation surface and the attachment surface of the packaging stabilizing means 40 is arranged at a position near the front fold line L1 on the back surface of the packaging material 30 of the front portion 21, and the other is the back surface of the packaging material 30 of the rear portion 24. It is arranged at a position close to the broken line L3.
For example, when the front folding line L1 is on the outside and the rear folding line L3 is on the inner side in the individual packaging state, the arrangement position of the packaging stabilizing means 40 is a distance from the rear folding line L3 of 2 mm or more, preferably 3 mm or more, more preferably 5 mm. That's it. And as for the arrangement position of the packaging stabilization means 40, the distance from the back folding line L3 is 12 mm or less, Preferably it is 10 mm or less, More preferably, it is 7 mm or less. More specifically, the thickness is 2 mm to 12 mm, preferably 3 mm to 10 mm, and more preferably 5 mm to 7 mm. When the front fold line L1 is on the outside and the front fold line L1 is on the inner side in the individual packaging state, the arrangement position of the packaging stabilizing means 40 is the distance from the front fold line L1, and the distance is the distance from the rear fold line L3. It is equivalent. Thus, by making the distance from the inner folding line to the packaging stabilizing means 40 within the above range, it becomes difficult for dust to enter the individual package 20. Moreover, it becomes easy to open the individual wrapping body 20 with a broken line part on the outside.

  Furthermore, it is preferable that the arrangement | positioning position of the packaging stabilization means 40 has overlapped with the position in which the main body slip prevention material 9 of the sanitary napkin 10 exists in planar view. That is, in the individual packaging state, the main body misalignment stopper 9 and the installation surface and the adherend surface of the packaging stabilization means 40 are disposed at overlapping positions. A packaging material 30 is detachably bonded to the main body displacement stopper 9. As a result, when the packaging material 30 in an individually packaged state is opened with the portions of the front fold line L1 and the rear fold line L3, the packaging material 30 of the adherend portion of the packaging stabilization means 40 is opened without being stretched or torn. It becomes easy.

  Further, the main body displacement stopper 9 may exist from the center in the longitudinal direction of the sanitary napkin 10 to the front fold line L1 and the rear fold line L3 to the front end direction of the sanitary napkin 10. The packaging material 30 covering the main body misalignment stopper 9 may be a film or non-woven fabric that has been directly peeled off, or may be a separate sheet such as release paper having a size that can cover the main body misalignment stopper 9. A body release sheet (not shown) may be adhered to the packaging material 30 for use. In that case, in order to obtain the effects as described above, it is preferable that the part where the separate release sheet and the packaging material 30 are bonded, the installation surface and the attachment surface of the packaging stabilization means 40 overlap. . The main body displacement stopper 9 is disposed on the non-use surface side of the sanitary napkin 10 and is used by pasting the sanitary napkin 10 on shorts. Considering the remaining adhesive material on the shorts of the coated area and the ease of taking out from the individual packaging material (not shown), even if it is applied continuously (in a plane) (so-called solid coating) Although it is good, it is preferable that it is applied intermittently. Examples of the intermittent coating form include a spiral shape, a stripe shape extending in the width direction, an Ω shape, and a dot shape. The body misalignment stopper 9 is positioned substantially in the center in the front-rear and left-right direction of the body portion on the non-use surface side of the sanitary napkin 10, the width is 35 to 70 mm, and the length is 65 to 65 mm with respect to the length of the sanitary napkin 10. It is preferable that it is in the range of 85%. From the viewpoint of preventing the sanitary napkin 10 from twisting and slipping during use, a rectangular region including all the adhesive portions of the main body slip stopper and having a rectangular shape in plan view is the absorber. Almost the same or slightly smaller width and length.

For example, when a hot melt adhesive is used, the packaging stabilization means 40 can maintain the sealing property if the adhesive strength is 0.01 N / cm or more, and the adhesive strength of the hot melt adhesive is AIKOH. The peel force measured using a push-pull gauge is 1 N or less, preferably 0.7 N / cm or less, more preferably 0.5 N / cm or less. More specifically, 0.01 N / cm to 1 N / cm, preferably 0.01 N / cm to 0.7 N / cm, and more preferably 0.01 N / cm to 0.5 N / cm.
Further, the width of the hot melt adhesive is 50% or more, preferably 65% or more, more preferably with respect to the width of the individual packaging material (the width here is the same direction as the product width direction at the time of individual packaging). Have the same width as the individual packaging.
By setting the adhesive force, width, and length of the packaging stabilizing means 40 within the above ranges, the front portion 21 and the rear portion 24 of the packaging material 30 are sufficiently bonded, so that the front folding line in the individual packaging state Waste or the like from between L1 and the rear folding line L3 does not enter the inside of the individual package 20, particularly the skin contact surface of the sanitary napkin 10. Therefore, the individual package 20 can be carried sanitarily.

The individual package 20a has the following effects.
As described above, since foreign substances such as dust do not enter the inside of the individual package 20, particularly the skin contact surface of the sanitary napkin 10, the individual package 20 can be carried in a sanitary manner.
In addition, since the front folding line L1 and the rear folding line L3 of the individual package 20a are arranged so as not to overlap with each other, the opening operation is performed by opening the packaging material 30 with one of the broken line portions. It becomes easy. In particular, in the case of the slim type sanitary napkin 10, the thickness of the folded state at the front folding line L1 or the folding line at the rear folding line L3 is as thin as about 3.5 mm to 5 mm, so the positions of the front folding line and the rear folding line are shifted. As a result, any one of the broken line portions can be easily picked, and the effect of facilitating the opening operation is great. As described above, the present invention is particularly effective for thin products.
Furthermore, since the tab tape for taking out for opening is not used, the problem that the packaging material 30 is torn at the time of opening or it is difficult to open can be solved by using the tab tape.
Further, in the state of being put in the interior pack, the package of the thin sanitary napkin tends to be small, and it is difficult to stand out at the store. However, it is possible to obtain an effect of increasing the appearance at the store by folding the individual mobile phone into four, folding and displaying.

For example, as shown in FIG. 1, when the front folding portion L1 protrudes beyond the rear folding portion L3, the outermost layer surface on the non-skin contact surface side of the front portion 21 and the central rear portion 24 is colored. A shift pattern between the front fold line L1 and the rear fold line L3 can be easily visually recognized by providing different patterns and different colors or arrangements of the patterns. In addition, the packaging material 30 has a pattern or coloring, and it is easy to visually recognize that the packaging material 30 does not overlap in the folded state. In addition, what is necessary is just to make it the same different relationship in the rear part 24 and the center front part 22 when the back folding part L3 protrudes rather than the front folding part L1. In short, the means for facilitating the visual recognition is due to the difference in the pattern or the color or the color arrangement of the front part 21 and the central rear part 23 or the rear part 24 and the central front part 22.
In these cases, it is necessary for the packaging material 30 to have transparency that allows the pattern or color to be seen through. Transparency can be evaluated by the transparency Tp. The greater the transparency Tp, the higher the transparency and the see-through effect. The transparency Tp is calculated by the following (formula 1) using the back black value LB, the back white value LW, the white measured value LW0, and the black measured value LB0 measured by the following measurement method.
(Expression 1) Transparency Tp = {(LW0−LB0) / (LW−LB)} × 100

<Measurement Method of Back Black Value LB, Back White Value LW, White Measurement Value LW0, and Black Measurement Value LB0>
For the measurement, a handy simple spectral color difference meter NF333 manufactured by Nippon Denshoku Industries Co., Ltd. was used as an operation pen type. C / 2 was used as the light source. A tip diameter of φ8 mm was selected at the tip of the NF333 pen type sensor. In the measurement on the standard plate attached to NF333 with a tip diameter of φ8 mm, the measured values of the white reference plate are L * value 96, a * value −1, b * value 2, and the measured value of the black reference plate The L * value was 0, the a * value was 0, and the b * value was 0. These measured values are average values of three measurements.
The L * value was measured three times by applying the attached standard black plate to the spectral color difference meter NF333, and the average value thereof was defined as the back black value LB. Further, the L * value was measured three times in the same manner as described above except that the standard white plate attached to the spectral color difference meter NF333 was used instead of the standard black plate, and the average value thereof was defined as the back white value LW. Next, the packaging material was overlapped on the standard white plate, the L * value was measured three times, the average value thereof was set as the white measured value LW0, and the color measured value LB0 using the standard black plate black was used instead of the standard white plate. The packaging material 30 having transparency has a transparency Tp of preferably 10 to 90, more preferably 15 to 85, and still more preferably 15 to 80.
Alternatively, the same effect can be obtained by arranging colors and patterns on the packaging material 30 to have the same arrangement relationship.

  Next, a preferred embodiment (second embodiment) of an individual package of absorbent articles according to the present invention will be described below with reference to FIG.

  As shown in FIG. 2, the absorbent article wrapped in the individual package 20 (20b) of the absorbent article of the second embodiment is a thin sanitary napkin 10 called a slim type as described above. . Hereinafter, the individual packaging body of a thin sanitary napkin will be described in detail.

The individual configurations of the sanitary napkin 10, the packaging material 30, the packaging stabilization means 40 (see FIG. 1), etc. of the individual packaging body 20 b of the second embodiment are the same as those described above except for how to fold the sanitary napkin 10. It is the same as the body 20a.
That is, the packaging material 30 has a front fold line L1, a center fold line L2, and a rear fold line L3, and is divided into a front part 21, a center front part 22, a center rear part 23, and a rear part 24 by each fold line. The napkin 10 is folded in four in the longitudinal direction in a state in which the napkin 10 is adhered to the packaging material 30 so as to be peelable by the main body misalignment stopper 9. In this example, the packaging material 30 is folded in four, and the sanitary napkin 10 is folded in three. The sanitary napkin 10 protrudes outward from the front portion 21 of the packaging material 30 in the longitudinal direction, the rear portion 24 of the packaging material 30 protrudes outward from the sanitary napkin 10, and the sanitary napkin 10 from the packaging material 30 in the width direction. The napkin 10 is shorter. Therefore, the sanitary napkin 10 is folded together with the packaging material 30 at the front folding line L1 and the central folding line L2, and only the packaging material 30 is folded at the rear folding line L3.

That is, the packaging material 30 is folded together with the sanitary napkin 10 so that the front fold line L1 faces the sanitary napkins 10 of the front part 21 and the central front part 22 facing each other. The sanitary napkin 10 is folded so that the rear part 24 of the packaging material 30 of the center rear part 23 and the rear part 24 and the sanitary napkin 10 face each other at the folding line L3.
Similar to the individual package 20a, the front fold line L1 and the rear fold line L3 are not overlapped in an individual packaging state and are arranged at positions shifted from each other.
And the packaging stabilization means (not shown) is distribute | arranged to the back surface of the packaging material 30 of the position near the front folding line L1 of the front part 21, and the position near the rear folding line L3 of the back part 24. FIG.

  The sanitary napkin 10 used for the individual package 20b is a sanitary napkin 10 having a wing 5 and having no hip guard. Similar to the sanitary napkin 10 of the first embodiment, a sanitary napkin 10 having a hip guard is used. May be.

  The individual package 20b has the same effect as the individual package 20a.

  The individual package 20 (20b) includes only the release sheet 11 in the configuration of the individual package 20a described above. The configuration of the sanitary napkin 10 is such that the wing 5 is arranged and the hip guard is not arranged. Each wing 5 is provided with adhesive portions 7 and 7, respectively. The adhesive sheets 7 and 7 are provided with a release sheet 11 similar to that of the first embodiment described above.

The packaging material 30 is folded together with the sanitary napkin 10 and the release sheet 11 so that the surfaces of the front portion 21 and the central front portion 22 on which the sanitary napkins 10 are arranged face each other at the front fold line L1. The surface of the central rear portion 23 on which the sanitary napkin 10 is disposed and the rear portion 24 are folded so as to face each other at the rear folding line L3. At that time, when the release sheet 11 is applied to the front fold line L1, the release sheet 11 is also folded at the front fold line L1. In this example, the sanitary napkin 10 of the front part 21 and the center front part 22 are folded so that the skin contact surfaces of the front part 21 and the center front part 22 face each other via the release sheet 11 at the front fold line L1, and the center rear part at the rear fold line L3. 23 is folded so that the skin contact surface of the sanitary napkin 10 and the surface of the packaging material 30 of the rear portion 24 face each other. Further, the sanitary napkin 10 is folded at least at the center fold line L2 so that the skin contact surface is inside the individual package 20, and the non-skin contact surface of the front portion 21 and the non-skin contact of the rear portion 24 are provided. The tangent faces are opposite. That is, in this example, the packaging material 30 is folded in four, and the sanitary napkin 10 is folded in three.
And like the said individual package 20a, the front fold line L1 and the back fold line L3 are distribute | arranged to the position which mutually shifted | deviated, without overlapping in an individual packaging state.

Although not shown, the packaging material 30 is extended longer than the sanitary napkin 10 in the longitudinal direction instead of arranging the release sheet 11, and the front fold line L1 and the rear fold line L3 are not on the sanitary napkin 10, It is located only in the packaging material 30. Furthermore, the specification which has the length which covers the adhesion part 7 of the wing 5 may be sufficient as the front part 21 of the packaging material 30 in the state folded at the front folding line L1. In that case, the packaging material 30 is folded in four, and the sanitary napkin 10 is folded in two.
In this specification, since a separate release sheet is not used, processing is further simplified.
In addition, since the product has a small number of folds, the difficulty of attaching the sanitary napkin 10 to the shorts can be reduced, and the sanitary napkin 10 can be firmly fixed to the shorts, and the uncomfortable feeling during use is also reduced.

The individual package 20b has the same effect as the individual package 20a.
Moreover, as above-mentioned, in the individual packaging body 20b, the front part 21 of the packaging material 30 has a function of the peeling sheet of the adhesion part 7 of the wing 5, and the front part 21 of the packaging material 30 is the adhesion part 7 of the wing 5. It can have a function of a release sheet. For this reason, since a separate release sheet is not required, there is an advantage that the release sheet is free of dust, and the handling of the packaging material 30 after opening the individual package 20b is facilitated.

In each of the above-described embodiments, the side portions in the width direction of the packaging material 30 are joined in a state of being folded and overlapped. An existing method can be adopted as the bonding method, and examples thereof include emboss bonding and bonding with a hot melt adhesive.
The sanitary napkin 10 used in each of the above embodiments may have the wing 5 and the hip guard 6 or may have only the wing 5.

Moreover, as shown in FIG. 3, in each embodiment, in the state where the individual package 20 folded at the front fold line L1 and the back fold line L3 is opened, a mark for distinguishing the front-rear direction of the sanitary napkin 10 is the release sheet 11, 13 or the packaging material 30 is preferable. In the drawing, as an example, a configuration in which a mark 50 is displayed on the packaging material 30 of the front portion 21 and the release sheet 13 is shown. The mark 50 may be characters such as “front” and “rear” as shown, or may be an arrow or a figure (not shown), as long as the front side and the rear side can be distinguished.
As described above, the mark 50 that can distinguish the front side and the rear side is displayed, so that the opening operation can be performed without hesitation.

  Next, as an example of a method for removing the packaging material 30 from the sanitary napkin 10, a first example of the first embodiment will be described below with reference to FIG.

  As shown in FIG. 1B, the packaging material 30 in an individually packaged state is hooked on the finger at the portion of the rear fold line L3 disposed on the inner side of the front fold line L1, and the front fold line L1 is exposed outward. Pick up the part with your finger and start opening. First, the front part 21 and the rear part 24 bonded by the packaging stabilizing means 40 are peeled off. Furthermore, the side part of the packaging material 30 is peeled off and opened, and the folded central folding line L2 is opened. Next, as shown in FIG. 1 (a), the release sheet 11 is removed from the adhesive portion 7 by pinching the portion that is the free end of the end portion 11 e of the release sheet 11 extended from the fixing portion 12. While peeling, the packaging material 30 is turned to the non-skin contact surface side of the sanitary napkin 10 and peeled from the main body misalignment prevention material 9. Further, the release sheet 13 is peeled from the adhesive portion 8 of the hip guard 6 while being fixed to the packaging material 30. Therefore, since the opening operation of the packaging material 30 and the peeling operation of the release sheets 11 and 13 can be performed with one operation, the opening operation is simplified. Moreover, since the release sheets 11 and 13 are fixed to the peeled packaging material 30, it is easy to organize them. Furthermore, since the release sheet bonded to the adhesive part 7 and the adhesive part 8 uses two separate release sheets 11 and 13, the release sheet can be made smaller, and the amount of the release sheet used and the amount of dust can be reduced. .

  Next, the basic configuration of the thin sanitary napkin 10 used in each of the above-described embodiments will be described below with reference to FIG. In FIG. 4, the width direction of the sanitary napkin 10 is indicated by X, and the longitudinal direction is indicated by Y.

  As shown in FIG. 4, the sanitary napkin 10 includes a liquid-permeable top sheet 1 disposed on the skin contact surface side, and a liquid-impermeable back sheet 2 disposed on the non-skin contact surface side. A vertically long main body (also referred to as an absorbent main body) 4 having an absorbent body 3 having a liquid retaining property interposed between the top sheet 1 and the back sheet 2. The main body 4 has wings 5 extending outwardly on both sides of the central front part, and a hip guard 6 extending outwardly on both side parts from the central rear part to the rear part. The base portion of each wing 5 is an arc shape or a trapezoid with rounded corners in a state where the wing 5 is expanded, and the base portion is formed in a curved shape. In the drawing, the wing 5 is shown in a folded state. In addition, each base portion of the hip guard 6 is an arc shape or a mountain shape that draws a gentle curve in a state where each hip guard 6 is expanded, and the base portion is formed in a curved shape. In the drawing, the hip guard 6 is shown in a folded state.

The shape of the main body 4 is a vertically long shape having a longitudinal direction (Y direction) arranged from the lower abdomen side to the buttocks side via the wearer's crotch portion and a width direction (X direction) orthogonal thereto. It is. In the present invention, unless otherwise specified, the side in contact with the human body is referred to as the skin contact surface side or the surface side, and the side in contact with the underwear is referred to as the non-skin contact surface side or the back surface side. Further, a direction having a relatively long length in plan view of the sanitary napkin 10 is referred to as a longitudinal direction, and a direction orthogonal to the longitudinal direction is referred to as a width direction. The longitudinal direction typically coincides with the front-rear direction of the human body in a worn state.
The main body 4 can be made of a material usually used for this type of sanitary napkin or the like, and is not particularly limited.

  The top sheet 1 is preferably formed of a hydrophilic nonwoven fabric. The hydrophilic nonwoven fabric is an air-through nonwoven fabric, a point-bonded nonwoven fabric, a spunbonded nonwoven fabric, a spunlace nonwoven fabric, and a three-dimensionally shaped nonwoven fabric. A fiber that has been subjected to a hydrophilic treatment with a composite fiber of polyethylene terephthalate and polyethylene can be preferably used.

  The back sheet 2 is not particularly limited as long as it is waterproof and has moisture permeability. For example, a film is formed by melt-kneading a hydrophobic thermoplastic resin, a fine inorganic filler made of calcium carbonate or the like or an incompatible organic polymer, and the film is obtained by uniaxial or biaxial stretching. A porous film is mentioned. Examples of the thermoplastic resin include polyolefin. Examples of the polyolefin include high to low density polyethylene, linear low density polyethylene, polypropylene, polybutene and the like, and these can be used alone or in combination.

As the absorbent body 3, for example, a fiber aggregate or a combination of this and an absorbent polymer can be used. As the fibers constituting the fiber assembly, hydrophilic natural fibers such as pulp fibers, synthetic fibers (preferably subjected to hydrophilic treatment), and the like can be used. The basis weight is not particularly ^limited, preferably ^{150g / m 2 ~500g / m 2} . Moreover, the coating sheet which coat | covers the absorber 3 can also be used. This coated sheet includes thin paper such as hydrophilic tissue paper (thin paper), non-woven fabric made of hydrophilic fibers such as cotton and rayon, and non-woven fabric made by subjecting synthetic resin fibers to hydrophilic treatment (spunbond-meltblown) -Spunbond (SMS), spunbond-meltblown-meltblown-spunbond (SMMS), spunbond-spunbond-meltblown-spunbond (SSMS), etc. In the sanitary napkin 10 shown in FIG. 1, the upper absorbent body 3a is a lower absorbent body (not shown) at the center front portion 22 at a position that does not overlap with the folded wing 5 at the center in the article width direction. Arranged above. In this case, foldability, a reduction in bulkiness at the time of individual packaging, and ease of operation when the individual packaging body is opened can be obtained.

The wing 5 is made of a soft non-woven fabric having a high water repellency and a low fiber density, and its base is sandwiched and fixed between the top sheet 1 and the back sheet 2. In addition, each wing 5 has an adhesive portion 6 on the back side. The pressure-sensitive adhesive portion 6 is used to stick and fix the wing 5 to the underwear and prevent the sanitary napkin 10 from shifting with respect to the underwear. Various pressure-sensitive adhesive materials can be used without any particular limitation. A hot melt adhesive is used for the pressure-sensitive adhesive portion 6, and examples of the hot melt adhesive include a styrene-butadiene copolymer and a styrene-isoprene copolymer. And the wing 5 is bendable, and is folded to the surface sheet 1 side in the present invention. Therefore, the adhesive part 6 faces the front side.
Thus, since the wing 5 corresponding to the crotch has a soft non-woven fabric when the sanitary napkin 10 is used, even if this portion touches the skin, it feels soft and feels not stiff like a film.
The said wing 5 is not limited to the said form, It distribute | arranges so that it may extend outside the both sides of the main body 4, has the said adhesion part 7, and folds it to the surface sheet 1 side. Any form can be used as long as it is.

  The said wing 5 peels a peeling sheet (not shown) from the said adhesion part 7, winds around the crotch part of a wearer's shorts, affixes it, and fixes the above-mentioned adhesion part 6 as a fixing material. Yes. The wing 5 is disposed in a region facing the excretion part (vagina opening) of the main body 4. This excretory part facing region is the central portion in the longitudinal direction of the sanitary napkin 10 for daytime use, and is the front in the longitudinal direction of the sanitary napkin 10 for use at night time. That position is set.

  The hip guard 6 is mainly disposed on the sanitary napkin 10 for night use and is made of the same material as the wing 5. Therefore, the same material effect as the wing 5 can be obtained.

The release sheets 11 and 13 described with reference to FIG. 1 and the like can be made of the same material as that of a general sanitary napkin release sheet. Specifically, the coating amount of the silicone treatment agent is as follows. For example, 0.1-5 g / m < ² > exfoliated fine paper, glassine paper, polyethylene film, composites thereof and the like can be mentioned. This peeling treatment can be performed using a known method. Further, the release sheets 11 and 13 may have any size as long as the outer shape covers both of the adhesive portions 7 and 8, and does not necessarily have to be rectangular as illustrated. Any shape may be used as long as the adhesive portions 7 and 8 are completely covered, and in addition to a rectangle (rectangle, square), for example, a polygon, an oval, an ellipse, a circle, or their The shape may be a partially extended shape, a partially narrowed shape, or the like.

  As the material of the packaging material 30 described with reference to FIG. 1 and the like, known materials can be used, and specifically, polypropylene, polyester, polyethylene, polyvinyl alcohol, or nonwoven fabric or paper having a thickness of 5 to 50 μm. And packaging materials such as these composite materials. The peeling treatment of the inner surface of the packaging material 30 can be performed using a known technique. Specifically, a peeling treatment agent is applied to the entire inner surface of the packaging material, or a peeling tape, a release paper, a peeling treatment.
