The description of this specification and the accompanying drawings will clarify at least the following matters.
A plurality of absorbent articles having a vertical direction and a horizontal direction intersecting each other, a bag member accommodating the plurality of absorbent articles, and a seal member provided at least partially separably from the bag member. The bag member has an opening defining portion that defines an opening, the sealing member has an adhesive portion, and the bag member has an opening defining portion so as to cover the opening defining portion. It is bonded so that the opening defining portion is broken and the opening is formed by separating the part of the sealing member from the bag member along the vertical direction. The absorbent article includes an absorbent body and a packaging material for packaging the absorbent body, and has a vertical direction and a horizontal direction intersecting each other, and the vertical direction of the absorbent article is the bag. The absorbent article is housed in the bag member along the vertical direction of the member, and the maximum value of the width of the packaging material in the lateral direction when the absorbent article is taken out from the bag member. Is greater than the maximum width of the absorbent body in the lateral direction, and the maximum width of the opening in the lateral direction is greater than the maximum width of the absorbent body in the lateral direction. The maximum value of the width of the opening in the left-right direction is smaller than the maximum value of the width of the packaging material in the lateral direction, and the maximum value of the width of the adhesive portion in the left-right direction is the said of the absorbent body. It is an absorbent article packaging characterized by being larger than the maximum value of the width in the lateral direction.

According to such an absorbent article packaging body, when the absorbent article is taken out from the bag member, both ends in the lateral direction of the packaging material are caught in the regions on both sides in the left-right direction of the opening, so that the absorbent body is natural. It is suppressed that it pops out. On the other hand, since the packaging material can be deformed so as to be narrower than the width of the opening, it can be easily taken out from the opening by the user pulling strongly. Further, since the highly rigid sealing member is adhered to the opening of the bag member via the adhesive portion, it is possible to prevent the width of the opening from being narrowed. This makes it easier for the user to take out the absorbent articles one by one.

It is desirable that the adhesive portion is provided on the outer side of the seal member adhered to the bag member in the left-right direction with respect to the opening defining portion in the absorbent article packaging body.

According to such an absorbent article package, when the absorbent article package is opened, a part of the adhesive portion is exposed in the outer region of the sealing member in the left-right direction from the opening defining portion. .. Then, the user attaches the finger holding the seal member to the exposed adhesive portion, so that the seal member becomes less slippery and it becomes easier to maintain the state in which the seal member is peeled off. Thereby, the absorbent article can be stably taken out easily.

In such an absorbent article package, it is desirable that the width of the adhesive portion in the left-right direction is larger than the maximum value of the width of the opening defining portion in the left-right direction.

According to such an absorbent article packaging body, a highly rigid sealing member is adhered via an adhesive portion so as to cover the entire area of the opening in the left-right direction, and the width of the opening in the left-right direction is narrowed. It becomes easier to suppress that. Further, when the absorbent article package once opened is resealed, the entire opening is easily covered by the sealing member, and the absorbent article package is easily sealed. This makes it easier to take out the absorbent article and keep the hygiene of the absorbent article housed inside.

Among the adhesive portions provided on the seal member, the absorbent article package has a pulling direction, which is the direction in which the seal member is pulled when the seal member is separated from the bag member. The adhesive force per unit area in the region having a predetermined width from the upstream end in the pulling direction is the adhesive force per unit area in the region having the predetermined width from the downstream end in the pulling direction. It is desirable to be weaker than.

According to such an absorbent article packaging body, the sealing member is less likely to be separated from the bag member due to the strong adhesive force at the terminal portion when the sealing member is peeled off. On the other hand, due to the weak adhesive force at the free end portion of the sealing member at the time of opening, even if the absorbent article comes into contact with the free end portion when the absorbent article is taken out from the absorbent article package, the seal member sticks to the free end portion. It is possible to prevent it from being lost.

In such an absorbent article package, the length of the opening formed in the front surface of the absorbent article package in the vertical direction is ½ of the length of the absorbent article in the vertical direction. Is also desirable.

According to such an absorbent article package, it is possible to reduce the proportion of the absorbent article exposed from the front side of the opening in the state of being housed in the bag member. Therefore, it becomes easy to prevent the absorbent article from naturally popping out to the front side of the bag member.

In such an absorbent article packaging body, the bag member is a pair of folding portions in which a part of a region on the upper end side in the vertical direction of the surfaces on both sides in the left-right direction is folded inward in the left-right direction. It is desirable that the distance between the pair of the folding portions in the left-right direction is larger than 1/4 of the length of the absorbent body in the lateral direction.

According to such an absorbent article package, when an attempt is made to move the absorbent article upward, at least a part of the absorbent body in the lateral direction is likely to be caught in the folded portion, and the upward movement is restricted. As a result, it is possible to prevent the absorbent article contained in the bag member from naturally popping out upward from the opening.

In such an absorbent article packaging body, the bag member is a pair of the folds in which a part of a region on the lower end side in the vertical direction of the surfaces on both sides in the left-right direction is folded inward in the left-right direction. It is desirable to have a part.

According to such an absorbent article package, each of the upper surface and the lower surface of the bag member is reinforced by the folding portion, and the bag member can easily maintain the shape of a substantially rectangular parallelepiped. Therefore, even when the number of absorbent articles housed inside is small, the bag member can stand on its own, and the user can use the absorbent article through the opening provided on the upper side (and front side) of the self-supporting bag member. It will be easier to take out.

The absorbent article package has the opening in at least a part of the upper surface portion of the absorbent article package, and the absorbent article is said to be at the lower end of the bag member in the vertical direction. It is desirable that the upper end of the absorbent article be visible from the opening while the lower end in the vertical direction is in contact with the absorbent article.

According to such an absorbent article package, the user can recognize at a glance the absorbent article housed inside from the outside of the absorbent article package. Therefore, when the absorbent article is taken out from the bag member, it becomes easy to grasp the absorbent article, and it becomes easy to confirm the number of the absorbent articles contained therein.

FIG. 5 is a plan view showing the seal member 40.

As shown in FIGS. 1 and 2, the absorbent article packaging body 10 has a plurality of absorbent articles 20, a bag member 30 for accommodating the plurality of absorbent articles 20, and a sealing member 40. There is. In addition, the absorbent article package 10 has a vertical direction, a front-rear direction, and a left-right direction that intersect with each other. In the vertical direction, the side from which the absorbent article 20 is taken out is "upper", and the opposite side is "lower". Also in the front-rear direction, the side from which the absorbent article 20 is taken out is referred to as "front", and the opposite side is referred to as "rear".

A sanitary napkin (hereinafter, also referred to as “napkin 20”) will be described as an example of the absorbent article 20 according to the present embodiment, but the absorbent article 20 is not limited to the sanitary napkin, but is a panty liner or light. Incontinence pads and the like are also included.

The napkin 20 is an individual package in which the absorbent main body 21 is packaged by a packaging sheet 22 which is a packaging material. FIG. 3A shows a state in which the napkin 20 is unfolded, and FIG. 3B shows a product state (individual packaging state) in which the napkin 20 is folded from the unfolded state of FIG. 3A. The napkin 20 has a vertical direction and a horizontal direction, and in the unfolded state of FIG. 3A, the absorbent main body 21 and the packaging sheet (packaging material) 22 are overlapped in the thickness direction. As the material of the packaging sheet 22, for example, various films such as a plastic film and a nylon film, and a deformable sheet member such as a non-woven fabric and a film obtained by laminating a non-woven fabric are used.

The absorbent main body 21 and the packaging sheet 22 are folded in three in the vertical direction so that the packaging sheet 22 is on the outside at predetermined positions F1 and F2 in the vertical direction from the unfolded state shown in FIG. 3A. Then, side seal portions 23 are formed at both ends of the napkin 20 in the lateral direction by joining the opposing surfaces of the packaging sheet 22 along the vertical direction, and the opening of the napkin 20 is fastened with the lead tape 24. As a result, the napkin 20 is in the state of an individual package as shown in FIG. 3B. In the present specification, of the napkin 20 in the product state of FIG. 3B, the side on which the lead tape 24 is provided is the back side, and the side on which the lead tape 24 is not provided is the front side. Further, as a method for forming (joining) the side seal portion 23, a well-known joining method such as a heat seal, an ultrasonic seal, an adhesive, and a combination thereof can be exemplified.

A predetermined symbol 25 is provided on the front side surface and the back side surface of the individually wrapped napkin 20 (packaging sheet 22). In FIG. 3B, the symbols 25a and 25b are provided at the upper and lower ends in the vertical direction on the front surface of the napkin 20, and the symbols 25c are provided near the central portions in the vertical and horizontal directions. Further, on the back surface of the napkin 20, the symbol 25d is provided in the region on the upper side of the lead tape 24 in the vertical direction. The shape and arrangement of the symbols, the number of symbols, and the like are arbitrary and are not limited to the example of FIG. 3B.

As shown in FIG. 2, the bag member 30 houses a plurality of napkins (absorbent articles) 20. In the bag member 30, each napkin 20 is inserted so that the side seal portions 23 at both ends in the lateral direction of the napkin 20 are inserted along both side portions in the left-right direction of the bag member 30. That is, each napkin 20 is inserted into the bag member 30 so that the vertical direction of the napkin 20 is along the vertical direction of the absorbent article packaging body. Further, the plurality of napkins 20 are housed so as to be lined up in the front-rear direction of the bag member 30. At that time, the rear side surface of each napkin 20 (that is, the surface to which the lead tape 24 is fastened) is inserted so as to face the rear side of the bag member 30.

Further, as shown in FIG. 4, in the state before the absorbent article packaging body 10 is first opened, the bag member 30 has an opening defining portion 32 such as a perforation for defining the opening 31 shown in FIG. (Hereinafter also referred to as "perforation 32"). In FIG. 4, the range of the seal member 40 is shown by a two-dot chain line for convenience, and the seal member 40 is shown through the seal member 40 in order to make the position of the perforation 32 (dotted line portion) easy to understand. Since the perforation 32 is located inside the outer edge of the seal member 40, the entire perforation 32 is covered by the seal member 40.

As can be seen from FIG. 4, the sealing member 40 is provided so as to cover at least a part of the upper surface of the absorbent article packaging body 10 and further cover at least a part of the front surface of the absorbent article packaging body 10. That is, the seal member 40 is provided so as to straddle the boundary between the upper surface and the front surface of the absorbent article packaging body 10. The sealing member 40 is provided with a knob portion 41, and the user can easily open and reseal the absorbent article package 10 by pinching and pulling the knob portion 41.

<About opening the absorbent article packaging body 10>
Subsequently, the operation when opening the absorbent article packaging body 10 will be described. FIG. 5 is a plan view illustrating the arrangement of the seal member 40 and the perforation (opening defining portion) 32. The seal member 40 has an adhesive portion 140 on one surface in the thickness direction (the surface opposite to the bag member 30), and is adhered (attached) to the bag member 30 via the adhesive portion 140. Has been done. In FIG. 5, the state in which the seal member 40 is adhered to the bag member 30 so as to cover the perforation 32 is shown in a plane.

The adhesive portion 140 is formed by applying a predetermined adhesive ad in a layered manner on the entire surface of the seal member 40 on one side in the thickness direction (the surface on the side facing the bag member 30). However, since it is easier to pinch the knob portion 41 of the seal member 40 if it is not adhered (attached) to the bag member 30, the adhesive ad does not have to be applied to the knob portion 41. As the adhesive ad, for example, a commercially available adhesive, a hot melt type adhesive, or the like can be used.

Further, when the seal member 40 is separated from the bag member 30, the direction in which the seal member 40 is pulled is defined as the "pulling direction". That is, the pulling direction is a direction along the vertical direction and the front-rear direction of the absorbent article packaging body 10 (bag member 30). The knob portion 41 described above is provided on one side (upstream side) of the pulling direction.

At the time of the first opening of the absorbent article packaging body 10, the user pinches the knob portion 41 of the seal member 40 and partially peels off the seal member 40 from the upstream side to the downstream side in the pulling direction. For example, in FIG. 4, the seal member 40 is gradually peeled off from the lower side in the vertical direction to the upper side. At this time, only the seal member 40 is separated from the bag member 30 until the peeling of the seal member 40 reaches the point A located on the most upstream side in the pulling direction on the perforation 32. Then, when the peeling of the seal member 40 reaches the point A, the perforation 32 starts to break, and the inner portion of the bag member 30 surrounded by the perforation 32 remains attached to the seal member 40 and is bagged together. It is separated from the member 30.

That is, in the seal member 40, the region outside the perforation 32 (the region indicated by the shaded display portion in FIG. 5) is a portion where the seal member 40 is separated from the bag member 30 and peeled off. This region is referred to as a separation unit 45. On the other hand, the region surrounded inside the perforation 32 (and the region downstream of the perforation 32 in the pulling direction) is a portion where the seal member 40 is peeled off without separating the bag member 30. This region is referred to as a non-separable portion 46.

By pulling the seal member 40 (knob portion 41) in the pulling direction in this way, the broken perforations 32 become the openings 31 on the front surface and the upper surface of the bag member 30, and the user can use the napkin from the openings 31. 20 can be taken out. Further, even after the absorbent article packaging body 10 is opened once, the opening 31 is re-opened by covering the opening 31 with the sealing member 40 and attaching the sealing member 40 to the bag member 30 via the adhesive portion 140. Can be sealed. As a result, opening and resealing can be repeated, and the napkin 20 can be kept clean even after the absorbent article packaging body 10 is opened.

<About taking out the napkin 20>
Next, the operation of taking out the napkin 20 housed in the bag member 30 will be described. FIG. 6A is a view of a state in which a plurality of napkins 20 are housed in the opened bag member 30 as viewed from the front side in the front-rear direction. FIG. 6B is a diagram showing a cross section taken along the line AA of FIG. 6A.

As described above, each of the plurality of napkins 20 is housed in the bag member 30 so that its vertical direction is along the vertical direction of the bag member 30 and is arranged in the front-rear direction. At this time, each napkin 20 is housed so that the lower end portion of the napkin 20 in the vertical direction is in contact with the lower end portion of the bag member 30 in the vertical direction (that is, the bottom surface of the bag member 30). Then, when the napkin 20 is taken out from the bag member 30, each napkin 20 is pulled out (pulled) upward from the opening 31 formed on the upper side in the vertical direction (and the front side in the front-rear direction).

Note that FIG. 6A shows a state in which the individually wrapped napkin 20 is housed in the bag member 30 without being bent in the vertical direction and the horizontal direction. However, a part of the napkin 20 may be housed in the bag member 30 in a bent state. For example, at the time of manufacturing the absorbent article packaging body 10, both ends of the packaging sheet 22 of the napkin 20 in the lateral direction (that is, the portion where the side seal portion 23 is provided) are housed in the bag member 30 in a bent state. It may be done.

In the conventional absorbent article packaging body, when a plurality of absorbent articles (napkins) are contained in the bag member in this way, it is difficult to take out only one absorbent article from the plurality of absorbent articles (napkins). That is, since a plurality of absorbent articles are stacked in the thickness direction and housed so as to be in close contact with each other as shown in FIG. 6B, when a certain absorbent article is to be taken out, the absorbent articles (packaging sheets) adjacent to each other in the front and rear are arranged. ), And there is a risk that the adjacent absorbent articles will also pop out of the bag member. In addition, if the number of absorbent articles stored is small and frictional force does not easily act, a plurality of absorbent articles may pop out from the opening at once when the bag member falls down. ..

Therefore, in the absorbent article packaging body 10 of the present embodiment, the absorbent article (napkin) 20 is formed by appropriately adjusting the width of the opening 31 (opening defining portion 32) formed in the bag member 30 in the left-right direction. It is easy to take out one by one. Hereinafter, the size of the opening 31 will be specifically described.

First, as shown in FIG. 6A, the maximum value of the width W31 in the left-right direction of the opening 31 is set to be narrower than the maximum value of the width W22 in the lateral direction of the packaging sheet 22 of the napkin 20. With such a configuration, when the napkin 20 is pulled upward in order to take out the napkin 20 from the bag member 30, both ends in the lateral direction of the packaging sheet 22 are likely to be caught in the regions on both sides in the left-right direction of the opening 31. Become. Therefore, the napkin 20 is less likely to easily pop out from the opening 31. On the other hand, the packaging sheet 22 is a deformable soft sheet member formed of the nylon film or the like described above. Therefore, when the user pulls strongly upward in the vertical direction, the packaging sheet 22 is deformed so as to be narrower than the width W31 of the opening 31, and can be easily taken out from the opening 31. That is, only one napkin 20 pulled by the user to be taken out from the bag member 30 is taken out from the opening 31, and the other napkin 20 is hard to pop out from the opening 31 because the packaging sheet 22 is caught.

However, the maximum value of the width W31 in the left-right direction of the opening 31 needs to be wider than the maximum value of the width W21 in the lateral direction of the absorbent body 21. If the width of the opening 31 in the left-right direction is narrower than the width of the absorbent body 21 in the lateral direction, when the napkin 20 is taken out from the opening 31, both ends of the absorbent body 21 in the lateral direction are the openings 31. It gets caught in the areas on both sides in the left-right direction of. In general, since the absorbent main body 21 has a higher rigidity than the packaging sheet 22, the absorbent main body 21 is not easily deformed like the above-mentioned packaging sheet 22, and it is difficult to take it out from the opening 31. On the other hand, in the present embodiment, the maximum value of the width W31 in the left-right direction of the opening 31 is larger than the maximum value of the width W21 in the lateral direction of the absorbent body 21, so that the absorbent body 21 becomes the opening 31. The napkin 20 can be easily taken out from the bag member 30 without being caught.

Further, when the user takes out the napkin 20 from the bag member 30, one hand grasps both sides of the bag member 30 in the left-right direction, and the other hand pulls the napkin 20 upward in the vertical direction. .. At this time, the bag member 30 gripped by one hand may be compressed in the left-right direction and crushed, and the width W31 of the opening 31 may be narrowed. Specifically, the length (width) of the bag member 30 in the left-right direction is the same as the width W21 of the napkin 20 housed in the bag member 30 in the lateral direction of the highly rigid absorbent body 21. It may be compressed up to (width), and the width W31 of the opening 31 may be narrowed accordingly.

Therefore, in the absorbent article packaging body 10 of the present embodiment, the maximum value of the width W140 in the left-right direction of the adhesive portion 140 provided on the seal member 40 is made wider than the maximum value of the width W21 of the absorbent main body 21. There is. Since the seal member 40 has higher rigidity than the bag member 30 (described later), the seal member 40 having such high rigidity is adhered to the opening 31 of the bag member 30 via the adhesive portion 140. The portion to which the seal member is adhered is reinforced, and the opening 31 is less likely to be crushed. As a result, the width W31 of the opening 31 is prevented from becoming narrower than the width W21 of the absorbent body 21, and the napkin 20 can be easily taken out.

In this way, by appropriately adjusting the dimensions (W21, W22, W31) of each part of the absorbent article packaging body 10, any one of the plurality of napkins 20 housed in the bag member 30 can be easily selected. It is possible to take it out. Further, even when the bag member 30 falls down, it is possible to prevent the napkin 20 from popping out from the opening.

Further, it is desirable that at least a part of the adhesive portion 140 is provided in the region outside the perforation (opening defining portion) 32 in the left-right direction. With such a configuration, it is easy to maintain the state in which the seal member 40 is peeled off in the state where the absorbent article packaging body 10 (bag member 30) is opened as shown in FIG. For example, when the user takes out the napkin 20 from the bag member 30, the opening 31 is covered again by the seal member 40 by holding down the seal member 40 with the fingers of the hand holding the bag member 30. The operation of pulling out the napkin 20 is performed so as not to be broken. At this time, if the adhesive portion 140 is provided on the back surface side of the seal member (the side adhered to the bag member 30) in the region outside the perforation 32 in the left-right direction (separation portion 45 in FIG. 5). , A part of the adhesive portion 140 is exposed. Then, by temporarily attaching the exposed adhesive portion 140 to the finger holding the seal member 40, the seal member 40 becomes less slippery, and the seal member 40 is peeled off (that is, as shown in FIG. 2). , The state in which the opening 31 is open) can be easily maintained. As a result, the napkin 20 can be stably taken out easily.

Further, in the state where the absorbent article packaging body 10 is sealed, the width W140 of the adhesive portion 140 provided on the sealing member 40 in the left-right direction becomes larger than the maximum value of the width W31 in the left-right direction of the opening 31. (See FIG. 6A). With such a configuration, the highly rigid sealing member 40 is adhered via the adhesive portion 140 so as to cover the entire area of the opening 31 (opening defining portion 32) of the bag member 30 in the left-right direction, and the opening 31 is formed. It becomes easy to prevent the width W31 in the left-right direction from becoming narrow. Further, when the absorbent article packaging body 10 once opened is resealed, the entire opening 31 is easily covered by the sealing member 40, so that the absorbent article packaging body 10 can be easily sealed. This makes it easier to maintain the hygiene of the napkin 20 housed inside.

Further, as can be seen from FIG. 4, the sealing member 40 is arranged so as to cover at least a part of the upper surface of the absorbent article packaging body 10 and further cover at least a part of the front surface of the absorbent article packaging body 10. .. That is, the seal member 40 is provided so as to straddle the boundary between the upper surface and the front surface of the absorbent article packaging body 10. By arranging the seal member 40 in this way, even if the opening 31 is widely provided from the upper surface to the front surface, it is possible to firmly open and reseal. Further, the wide opening makes it easy to take out the napkin 20.

The seal member 40 is made of a member having higher rigidity than the bag member 30 and the like, and is shown in FIG. 6B in a state of being left for a while (that is, a natural state) after opening the absorbent article packaging body 10. The posture of covering the opening 31 from the upper surface side is maintained. Therefore, the sealing member 40 functions like a lid covering the upper surface side of the opening 31, and when the absorbent article packaging body 10 falls down, the napkin 20 pops out to the upper surface side of the bag member 30. It can be suppressed.

In the present embodiment, the specific range of rigidity (rigidity and softness) of the seal member 40 is 0.45 to 2.00 mN, more preferably 0.75 to 1.5 mN. The rigidity of the seal member 40 was measured as follows according to the bending resilience A method (Garley method) specified in JIS L1096: 2010. First, a plurality of types of rigid test pieces are prepared, with the opening direction (corresponding to the pulling direction) of the seal member 40 as the length direction and the direction perpendicular to it as the width direction. The test pieces have a length of 38 m and a width of 25 mm, and a plurality of test pieces are collected. Then, using a Garley stiffness tester (for example, Garley stiffness tester manufactured by Daiei Kagaku Seiki Seisakusho Co., Ltd.), make the long side of the test piece vertical and attach it to the chuck of the movable arm of the tester, and attach it to the pendulum. Attaches the prescribed weight. Next, the movable arm is rotated to the left or right at a specified speed, and the scale when the lower end of the test piece comes into contact with the pendulum once and then leaves the pendulum is read. This test is repeated multiple times, and the stiffness (garle stiffness) is calculated from the average of the measured values.

As a result, when the rigidity (rigidity / softness) of the sealing member 40 is less than 0.45 mN, wrinkles are likely to occur in the sealing member 40 when opening / resealing, which is sufficient for resealing. It was confirmed that it could not be sealed. On the other hand, it was confirmed that when the rigidity of the seal member 40 is larger than 2.00 mN, the operability is poor at the time of opening and the user is given the impression that it is difficult to take out the napkin 20 (product) from the bag member 30. .. In the present embodiment, by setting the rigidity of the sealing member 40 to 0.45 mN or more and 2.00 mN or less (preferably 0.75 to 1.5 mN), the opening / resealing operation can be easily performed and the sealing member 40 can be easily opened and resealed. Wrinkles are less likely to form and it is possible to easily ensure airtightness. Further, as described above, the napkin 20 can also have a function as a lid for suppressing the napkin 20 from popping out to the upper surface side of the bag member 30.

Further, the adhesive portion 140 in which the seal member 40 is adhered to the bag member 30 has a weaker adhesive force at the upstream end portion in the pulling direction than at the downstream end portion. In other words, the adhesive force per unit area in the region of the adhesive portion 140 having a predetermined width from the upstream end in the pulling direction is the adhesive force per unit area in the region having the same width from the downstream end. Weaker than.

The downstream end of the adhesive portion 140 in the pulling direction is a portion that serves as a terminal for peeling off the seal member 40 when the absorbent article packaging body 10 is opened, and must be inseparably joined to the bag member 30. be. Therefore, it is desirable to make the adhesive force as strong as possible at the downstream end. On the other hand, of the adhesive portion 140, the upstream end portion in the pulling direction is a portion that becomes the free end (tip) of the seal member 40 when the absorbent article packaging body 10 is opened, and when the napkin 20 is taken out from the bag member 30. In addition, it is a part that may come into contact with the napkin 20. Therefore, by weakening the adhesive force at the upstream end portion, it is possible to prevent the napkin 20 from sticking to the adhesive portion 140 when the napkin 20 is taken out.

Regarding the openability of the seal member 40, a test was conducted in which 30 users actually opened the seal member 40 using a plurality of types of seal member 40 having different adhesive strengths (adhesive strength) as samples, and "easy to open / easy to open / The evaluation was performed on a three-point scale of "favorable, neither can be said, difficult to open / not very preferable". Then, the one having "easy to open / preferable" of 70% or more was set as an appropriate opening strength.

The opening strength test was performed as follows. First, an auxiliary knob (not shown) of an aluminum sheet that is stronger than the breaking strength of the sealing member 40 and has almost no extensibility is attached to a portion corresponding to the knob portion 41. Next, the seal member 40 having the entire width of the adhesive portion 140 in the left-right direction and the package (bag member 30) corresponding to the width are cut out and held by a tensile tester (for example, a tensile tester manufactured by Instron). The bag member 30 and the seal member 40 were peeled off in the 180-degree direction. Then, the magnitude of the force required to peel off the seal member 40 (sample) by a predetermined width was measured, and the adhesive strength was evaluated.

As a result, when the adhesive strength of the sealing member 40 is 1.25N / 25mm to 3.5N / 25mm in the range from the opening start position to opening 25 mm in the pulling direction, the evaluation of "easy to open / preferable" is made. It exceeded 70%. That is, it was clarified that the adhesive strength of the absorbent article package 10 of the present embodiment is 1.25 N / 25 mm to 3.5 N / 25 mm, which is an appropriate opening strength. On the other hand, it was clarified that the sample of 1.0 N / 25 mm or less is not preferable because the adhesive force itself is weak and the package is unintentionally opened.

Further, as shown in FIG. 6A, the length L31 in the vertical direction of the opening 31 provided in the front surface of the absorbent article packaging body 10 (bag member 30) is a napkin (absorption) housed in the bag member 30. Sex article) It is smaller than 1/2 of the length L20 in the vertical direction of 20 (L31> 0.5 × L20). When the opening 31 is provided on the front surface of the bag member 30, if the length L31 of the opening 31 in the vertical direction is larger than half of the length L20 of the napkin 20 in the vertical direction, the napkin 20 is a bag. When housed in the member 30, a portion of the napkin 20 in the vertical direction or more is exposed from the opening 31. In this case, the napkin 20 may naturally pop out from the front side of the opening 31.

On the other hand, in the present embodiment, the length L31 of the opening 31 in the vertical direction is smaller than half of the length L20 of the napkin 20 in the vertical direction, so that the napkin 20 is exposed from the front side of the opening 31. The ratio can be reduced. Therefore, it becomes easy to prevent the napkin 20 from popping out to the front side.

Here, the structure of the bag member 30 (absorbable article packaging body 10) will be briefly described. 7A and 7B are schematic perspective views illustrating the structure of the bag member 30. When manufacturing the bag member 30, first, a substantially cylindrical base material (for example, vinyl resin or the like) along the vertical direction is prepared. Then, as shown in FIG. 7A, a perforation (opening defining portion) 32 is formed at a predetermined position on the surface 30F which is the front surface (and the upper surface) of the absorbent article packaging body 10 so as to cover the formed perforation 32. The seal member 40 is adhered. Next, the surfaces 30Sf and 30Sf, which are both left and right surfaces of the absorbent article packaging body 10, are between the front and rear surfaces (left and right) of the surfaces 30B and 30F, which are the rear surfaces (and upper surfaces) of the absorbent article packaging body 10. Fold in (inside the direction).

Subsequently, the upper end of the surface 30F and the upper end of the surface 30B are joined to each other to form the upper joint portion 30eu. Next, the surfaces 30Sf and 30Sf folded between the surfaces 30F and 30B are expanded in the front-rear direction to form a substantially rectangular parallelepiped bag member 30 as shown in FIG. 7B. At this time, a part of the upper end side region of the surface 30F becomes the upper surface of the bag member 30, and the region lower than the upper end side region becomes the front surface of the bag member 30. Similarly, a part of the upper end side region of the surface 30B becomes the upper surface of the bag member 30, and the portion lower than the upper end side region becomes the rear surface of the bag member 30. Then, on the surfaces 30Sf on both sides in the left-right direction, a part of the region on the upper end side is folded inward in the left-right direction to form a pair of folded portions 30 m. The folded portion 30 m constitutes a part of the upper surface of the bag member 30 as shown by the shaded portion in FIG. 7B.

After that, a plurality of napkins 20 are inserted from the lower side of the bag member 30, and the lower end of the surface 30F and the lower end of the surface 30B are joined to each other in the same manner as the upper surface side to form the lower joint portion 30ed (not shown). At the same time, the lower surface of the bag member 30 is formed. At the same time, a pair of folding portions 30m are formed on the lower surface side as well as the upper surface side. Through these steps, the absorbent article packaging body 10 in which a plurality of napkins 20 are housed in the bag member 30 is formed.

In the state where the absorbent article packaging body 10 is opened, a part of the pair of folding portions 30m and 30m provided on both side portions in the left-right direction and the upper end portion in the vertical direction is as shown in FIG. 6A. It is folded inward from the opening 31. In the absorbent article packaging body 10, the intervals G30 m in the left-right direction of the folded portions 30 m and 30 m on both the left and right sides are larger than 1/4 of the width W21 in the lateral direction of the absorbent main body 21. Therefore, when the napkin 20 is to be moved upward in the vertical direction, at least a part of the absorbent main body 21 in the lateral direction is likely to be caught in the folded portion 30 m, and the movement to the upper side is restricted. As a result, it is possible to prevent the napkin 20 housed in the bag member 30 from spontaneously popping out upward from the opening 31. Since the bag member 30 is made of a soft material such as vinyl resin, when the user takes out the napkin 20, the folded portion 30 m can be easily deformed by pulling strongly upward, so that the folded portion 30 m can be easily deformed. It is unlikely that 30 m itself will interfere with the removal operation of the napkin 20.

Further, by forming the folded portions 30 m at both ends in the vertical direction of the bag member 30, each of the upper surface and the lower surface of the bag member 30 is reinforced by the folded portions 30 m. As a result, the bag member 30 can easily maintain the shape of a substantially rectangular parallelepiped as shown in FIGS. 1 and 2. Therefore, the bag member 30 can stand on its own, and even when the number of napkins 20 housed inside is small, it can stand on its own as shown in FIG. 2, and the user is provided on the upper side (and the front side). The napkin 20 can be easily taken out from the opening 31.

Further, as shown in FIGS. 6A and 6B, the upper end of the napkin 20 in the vertical direction is in contact with the lower end of the bag member 30 in the vertical direction (that is, the lower surface). It is visible from the opening 31. Thereby, the user can recognize the napkin 20 housed inside from the outside of the absorbent article packaging body 10 at a glance. Therefore, when taking out the napkin 20 from the bag member 30, it becomes easy to grasp the napkin 20 and to confirm the number of the napkins 20 housed inside.

Further, when a plurality of napkins 20 are arranged side by side in the front-rear direction and housed in the bag member 30 as shown in FIG. 7B, it is desirable that the designs of the packaging sheets 22 of the two napkins 20 adjacent to each other in the front-rear direction are different from each other. .. Specifically, in two napkins 20 adjacent to each other in the front-rear direction, it is desirable that the colors, patterns, arrangements, and the like of the symbols 25 provided in the portions visible from the opening 31 are different from each other. For example, in FIG. 7B, the symbols 25a provided at the upper ends of the plurality of napkins 20 visible from the opening 31 are made different for each napkin 20. This makes it easier to identify each of the plurality of napkins 20 housed in the bag member 30, and makes it easier to take out the napkins 20 individually.

In FIG. 7B, assuming that 10 napkins 20 of 20A to 20J are housed in the bag member from the front side to the rear side, the design of the packaging sheet 22 (design 25) of the napkins 20A and 20B adjacent to each other in the front-rear direction. Etc.) are different, and the design (design 25, etc.) of the packaging sheet 22 is different between 20B and 20C. At this time, the design of the packaging sheet 22 may be different between the napkins 20A and 20C, or the design may be the same. For example, the napkins 20A to 20J may have different designs, or the two types of designs may be arranged alternately.
