Description

  The present invention relates to a package for absorbent articles.

Conventionally, absorbent articles such as sanitary napkins and panty liners (orimono sheets) are folded together with packaging materials, individually packaged, and marketed.
As an example of this packaging form, there is a packaging structure of an absorbent article that is composed of an absorbent article and a rectangular packaging material that individually wraps the absorbent article, and is sealed with a seal portion in which a part of the packaging material is fused. Yes (Patent Document 1). The sealing part is one in which one end of the packaging material is fused while leaving the other end, and also serves as an opening part with a strength of 200 g / 10 mm or less. That is, when the remaining other end portion is pulled up as a knob portion, the seal portion is peeled off and the packaging structure is opened.
Moreover, as another example, there is a continuous package body in which a plurality of packages in which absorbent articles (sanitary napkins) are individually packaged by an exterior sheet are continuous and can be separated for each package (Patent Document 2). . A seal processing portion and a cut line portion are arranged at a connection portion between the package bodies, and individual package bodies are cut off at the cut line portion. Each separated package is opened by an opening separation line portion 8 on its outer surface, and an absorbent article (sanitary napkin) is taken out. At that time, the opening separating line portion 8 is torn to the left and right (see FIGS. 4 and 5 of Patent Document 2).
As another example, there is one in which a hemispherical or rectangular unsealed portion formed by perforations is formed on the outer surface of the package (Patent Documents 3 and 4). When the package is opened along the perforation, the folded absorbent article (sanitary napkin) inside is developed.

  In the packaging structure of the absorbent article described in Patent Document 1, the seal portion serves as both the sealing portion and the opening portion of the package, and the seal strength is limited. On the other hand, in the package of Patent Document 2, when opening, it tears while tearing while raising the nail on the separation line part for opening or suppressing the surrounding package, so that a strong force is required and smooth opening Is difficult. Moreover, there was a possibility of damaging internal absorbent articles. Moreover, in the package body of patent document 3 and the individual bag of the napkin of patent document 4, since the opening part by a perforation is in the sheet | seat continuous surface without a sealing part, it opens, suppressing strongly so that the outer side of an opening part may not float. There must be. Further, at the time of opening, one end side of the internal absorbent article is lifted. These things, together with the shape that is difficult to open such as a hemispherical shape or a rectangular shape of the opening portion, require a relatively large force at the time of opening, and smooth opening is difficult.

Therefore, in practice, each component is in contact or bonded.

A preferred embodiment (first embodiment) of a package of absorbent articles according to the present invention will be described below with reference to FIG.
In the absorbent article package 20 of 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. Further, in this specification, in a state in which the garment is worn, the surface in contact with the wearer is referred to as a wearer contact surface or a skin contact surface, and is in contact with a relatively opposite surface, that is, the worn clothing. The side surface is referred to as a clothing contact surface or a non-skin contact surface. Further, the surface closer to the wearer is referred to as the wearer contact surface side or the skin contact surface side, and the surface closer to the clothing is referred to as the clothing contact surface side or the non-skin contact surface side.

  As shown in FIG. 1, the vertically long absorbent article 10 wrapped in the package 20 of the present embodiment is, for example, a sanitary napkin (hereinafter also referred to as a napkin). Hereinafter, the napkin package will be described in detail. Therefore, the vertically long absorbent article 10 will be described as a napkin 10. Further, the longitudinal direction of the napkin 10 is the longitudinal direction (hereinafter also referred to as the longitudinal direction). Hereinafter, the longitudinal direction or the longitudinal direction means the longitudinal direction or the longitudinal direction of the napkin 10 or a direction parallel to this direction.

The napkin 10 includes a liquid-permeable top sheet 1 disposed on the wearer contact surface side, a liquid-impermeable back sheet 2 disposed on the clothing contact surface side, the top sheet 1 and the back sheet 2. 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 therebetween, and wings 5 extending outwardly on both sides of the main body 4. (See FIG. 2).
The clothes contact surface of the back sheet 2 is provided with a shift stopper 13 that fixes the napkin 10 to the clothes. A release sheet 14 detachable from the misalignment stopper 13 is disposed so as to cover the misalignment stopper 13. Further, a release sheet fixing portion 15 for fixing the release sheet 14 is disposed on the inner surface of the exterior material 11, and the exterior material 11 is fixed to the release sheet 14. Therefore, the fixing portion 12 includes a slippage preventing portion 13 that fixes the clothing contact surface 10sw of the napkin 10 to the clothing, and a release sheet fixing portion 15 that fixes the release sheet 14 to the inner side surface of the exterior material 11. In the case where the release sheet 14 is provided, the fixing portion between the inner side surface of the exterior material 11 and the clothing contact surface 10sw side of the absorbent article (napkin 10) is, in a narrow sense, the release sheet fixing portion 15. means.

  The package 20 of the absorbent article is formed by folding the exterior material 11 together with the napkin 10 as the absorbent article in the vertical direction and sealing with the exterior material 11. Specifically, the package 20 is folded at least twice in the longitudinal direction of the napkin 10 with the wearer contact surface 10 sm side of the napkin 10 facing inside. In the illustrated example, it is folded twice at two locations of the first fold portion L1 and the second fold portion L2, thereby forming a so-called three-fold structure. And the one end part 11a side and the other end part 11b side of the cladding | exterior_material 11 are folded up and sealed with the package body sealing part 26. FIG. Thus, the napkin 10 is individually packaged by the exterior material 11, and the clothing contact surface side of the napkin 10 is bonded to the inner side surface of the exterior material 11 by a fixing portion 15 (hereinafter also referred to as a release sheet fixing portion 15). It is fixed. In the example of illustration, it has arrange | positioned at three places (fixing part 15A, 15B, 15C). The arrangement, the number, and the range of the fixing portions 15 are not limited to those of the present embodiment shown in FIG. 1A, and the ranges that do not hinder the action of the opening guide portion 25 and the package sealing portion 26 described later. Can be set as appropriate.

In the napkin 10 of the present embodiment, a garment contact surface 10sw is provided with a shift stopper 13 for fixing to the garment, and the shift stopper 13 is covered with a release sheet 14. The clothing contact surface side in this case means the outer surface side of the release sheet 14. That is, the release sheet 14, which is the clothing contact surface side of the napkin 10, is bonded and fixed to the inner surface of the exterior material 11 by the release sheet fixing portion 15. On the other hand, the slip stopper 13 and the release sheet 14 provided on the clothing contact surface 10sw are in a fixed state that can be separated so that they can be separated when the napkin 10 is used.
In this specification, “peeling” means that it can be easily picked up with a finger, and “adhesion” or “joining” means that it cannot be easily picked up with a finger.

  When the exterior material 11 is folded together with the release sheet 14 and the napkin 10, the exterior material 11 has a size that includes them. In the folded state, one end portion 11a of the outer packaging material 11 in the vertical direction is arranged to extend outward from one end portion 10a of the napkin.

  In the package 20, a region including the one end portion 11 a of the exterior material 11 outside the first folding portion L <b> 1 forms a first exposed region 21 that becomes the outer surface of the package 20. Further, the package 20 includes a central region 23 between the first fold portion L1 and the second fold portion L2, and a region 22 including the other end portion 11b of the exterior material 11 outside the second fold portion L2. . The first exposed region 21 and the region 22 including the other end portion 11 b overlap, and this portion forms an overlapping region 24. Each of the above regions includes the exterior material 11 and the napkin 10 that are divided by the regions. The overlap region 24 includes the exterior material 11 and the napkin 10 in the overlap of both the first exposed region 21 and the region 22 including the other end portion 11b.

In addition, although the packaging body 20 of this embodiment showed the form folded twice, this folding frequency is not limited to this, In the range in which the effect | action of the below-mentioned packaging body sealing part 26 and the opening guide line 25 is not inhibited. Can be set as appropriate. For example, although not shown, the region 22 including the other end portion 11b may be further extended to be folded in half and folded three times as a whole to form a so-called four-fold structure. In this case, the package sealing portion 26 and the opening guide line 25 described later are disposed in a region on the outer surface side in contact with the first exposed region 21 in the region 22 including the other end portion 11b. Therefore, the overlapping region 24 is a portion where the inner overlapping region which is a portion on the outer surface side in the region 22 including the other end portion 11b and the first exposed region 21 overlap.
Further, the length of the absorbent article and the exterior material can be appropriately changed as long as the functions of the package sealing portion 26 and the opening guide wire 25 described later are exhibited.

The overlapping region 24 is provided with a package sealing portion 26 that joins the exterior material 11 in the first exposed region 21 and the exterior material 11 in the region 22 including the other end portion 11b. Further, in the overlapping region 24, in the region 22 including the other end portion 11b, the opening guide portion 25 is disposed on the one end portion 11a side with respect to the package sealing portion 26. In the package 20 of the present embodiment, the opening guide portion 25 exists in the inner overlapping region and is covered with the exterior material 11 in the first exposed region 21.
Moreover, the one end part 11a of the exterior material 11 is extended beyond the end part 10a of the napkin 10 as above-mentioned. The portion outside the package sealing portion 26 in the extended portion is a free end that is not joined to the package 20. This free end portion becomes a handle portion 11G at the time of opening which will be described later.

  The packaging body sealing portion 26 joins the exterior materials at a portion where the one end 11a side and the other end 11b side of the exterior material 11 are folded. As shown in FIG. 1B, the package body sealing portion 26 is formed in a band shape over the entire width of the exterior material 11. In addition, side sealing portions 27 and 27 are arranged on both sides in the width direction of the packaging body 20 (see FIG. 1B), and the packaging body 20 is sealed together with the packaging body sealing portion 26. By these, the original function of the package body of preventing mixing of dust and the like from the outside and maintaining the cleanliness of the absorbent article inside is exhibited.

In the package 20, by providing the package sealing part 26 and the opening guide part 25 separately, the bonding strength between the exterior materials in the package sealing part 26 without considering the peel strength at the time of opening. Can be increased. It is preferable that the bonding strength G of the package sealing portion 26 has a bonding strength that can be withstand even when the package 20 is opened. Specifically, the bonding strength G of the package sealing portion 26 is preferably 100 g / 10 mm or more, more preferably 300 g / 10 mm or more, and further preferably 500 g / 10 mm or more. Within this range, it is easy to open from the opening guide part, and it is difficult to cause problems such as the bonding of the package sealing part 26 being dissociated and the sealing performance being impaired before use.
As will be described later, the packaging body sealing portion 26 pulls up and lifts the packaging body sealing portion lower portion 11P of the exterior material in the region 22 including the other end portion 11b together with the handle portion 11G of the first exposed region 21 when opened. This is the starting point for transmitting the force to the opening guide section 25.

(Measuring method of bonding strength G of package sealing part 26)
The exterior material is cut out with a width of 20 mm so that the napkin is in a strip shape in the vertical direction of the napkin, that is, in the direction orthogonal to the direction in which the package sealing part is continuous, and the package sealing part is located across the center. Next, in an environment of 20 ° C. and 65% RH, using a Tensilon tensile tester (Orientec Co., Ltd., trade name “RTA-100”), the exterior material end of the region including the other end of the lower chuck Is fixed to the upper chuck and the end portion of the exterior material on the first exposed region side is peeled off in the 180 ° direction at a peeling speed of 300 mm / min. The average of the maximum value of 5 points at that time is taken, and further the average of 3 samples is taken, and this is taken as the bonding strength G of the package sealing part 26.

As long as the above-mentioned bonding strength G can be obtained, various materials can be used as the forming material and the forming method of the package sealing portion 26 without particular limitation. For example, a hot melt adhesive coating film is used. As this hot melt adhesive, rubber-based, olefin-based, EVA-based hot melt, or the like can be used. Coating basis weight in the case of using the hot melt adhesive, to the above bonding strength, 20 g / ^{m 2} or more preferably, 50 g / ^{m 2} or more, more preferably, 100 g / ^{m 2} or more is more preferable. The upper limit is preferably 500 g / ^{m 2} or less, more preferably 300 g / ^{m 2} or less, 200 g / ^{m 2} or less is more preferred. Further, in the above range, it is preferably 20 g / m ² or more and 500 g / m ² or less, particularly 50 g / m ² or more and 300 g / m ² or less, more preferably 100 g / m ² or more and 200 g / m ² or less. When the basis weight is equal to or greater than the lower limit value, it is easy to obtain a sufficient bonding strength G. The upper limit may be considered in consideration of the cost of raw materials, but if it is about 500 g / m ² , the individual end portion of the first exposed area will be greatly floated by hot melt, so There is also a merit that the ease of pinching of the end portion is improved.

  Moreover, the side sealing part 27 mentioned above is based on means, such as adhesion | attachment by the coating film of a hot-melt-adhesive agent, the heat sealing | bonding of the exterior materials 11, and the joining by embossing, etc., for example.

On the other hand, the opening guide portion 25 is disposed on the exterior material 11 in the region 22 including the other end portion 11b inside the first exposed region 21, that is, below the first exposed region 21 that is the outer surface. . The opening guide part 25 and the package sealing part 26 are arranged in parallel while being separated from each other at a predetermined interval when the package 20 is viewed in plan as shown in FIG.
The opening guide portion 25 is a portion that can separate the exterior material 11 by an external force. For example, the perforations arranged in a line, the aggregate of perforations arranged in a line with a predetermined width, and the exterior material 11 arranged in a line do not cut in the thickness direction. Cuts, aggregates of cuts that do not lead to cutting in the thickness direction of the exterior material 11 arranged in a line with a predetermined width, grooves that weaken the tensile strength of the exterior material 11 linearly, and the tensile strength of the exterior material 11 For example, a group of holes weakened in a line is arranged in a line with a predetermined width. Not only this but the exterior material is torn at the opening guide portion 25 due to an external force, and the packaging material 20 is opened by separating the exterior material 11 in the region 22 including the other end portion 11b into two, with the boundary therebetween. Any configuration may be used as long as dust or the like does not enter the inside of the package 20 when it is not opened and the cleanliness of the inside can be maintained.

The peel strength H that separates the exterior material 11 of the opening guide portion 25 is preferably smaller than the above-mentioned bonding strength, specifically, preferably less than 500 g / 10 mm, more preferably less than 300 g / 10 mm, and less than 100 g / 10 mm. Further preferred. Further, the lower limit is preferably 30 g / 10 mm or more, more preferably 50 g / 10 mm or more, and further preferably 70 g / 10 mm or more. Furthermore, among the above ranges, the peel strength H is preferably 30 g or more and less than 500 g, particularly 50 g or more and less than 300 g, and more preferably 70 g or more and less than 100 g. When the peel strength H is within the above range, the opening operation becomes easy, and it is opened when transporting the product during production, transporting the product to the store, or when separating and selling the continuous package form at the store. It is difficult, and it becomes easy to maintain the sealing property until just before use.
By setting it as said range, the opening guidance | induction part 25 can perform opening quickly smoothly with a smaller force, ensuring the sealing performance at the time of unopening, as mentioned later.

(Measuring method of peel strength H of opening guide part 25)
The exterior material is cut out with a width of 20 mm so that it is strip-shaped in the vertical direction of the napkin, that is, in the direction orthogonal to the continuous direction of the opening guide part, and the package sealing part is located across the center. The exterior material is cut out in a band shape with a width of 20 mm so that the opening guide portion is located across the center. Next, in an environment of 20 ° C. and 65% RH, using a Tensilon tensile tester (Orientec Co., Ltd., trade name “RTA-100”), the exterior material end of the region including the other end of the lower chuck Is fixed to the upper chuck and the end portion of the exterior material on the first exposed region side is peeled off in the 180 ° direction at a peeling speed of 300 mm / min. At that time, the average of the maximum value of 5 points is taken, and further, the average of 3 samples is taken, and this is taken as the joining strength H of the opening guide portion 25.

An example of the opening method will be described with reference to FIG. 3A shows a cross section of the entire packaging body 20, and FIG. 3B partially shows the relationship between the exterior packaging material 11, the packaging body sealing portion 26, and the fixing portion 15A at the time of opening. It is sectional drawing shown. First, as shown in FIG. 3A, in the package 20, the handle portion 11G of the first exposed portion 21 is picked up with one hand and pulled up (for example, in the direction of arrow S1). The pulling-up force is transmitted to the region 22 including the lower end 11b on the lower side through the packaging body sealing portion 26, and the packaging body sealing portion lower portion 11P of the exterior material 11 is lifted. Further, the lifting force is transmitted from the package sealing portion 26 to the opening guide portion 25 in parallel therewith. As a result, as shown in FIG. 3B, with respect to the exterior material 11, the package sealing part lower part 11 </ b> P and the fixed part 11 </ b> Q to which the napkin 10 is fixed are separated, and the package 20 is opened.
Or it pulls in the 1st folding part L1 direction (for example, the direction of arrow S2) so that it may rotate centering on the package sealing part 26, pulling up the handle part 11G. The tensile force due to this rotation is transmitted to the opening guide portion 25 as a stronger separation force between the package sealing portion lower portion 11P and the fixed portion 11Q, and the packaging body 20 shown in FIG. . That is, the exterior material 11 is separated with a smaller force, and the package 20 is smoothly and quickly opened.

  As described above, in the package 20, by combining the package seal part 26 and the opening guide part 25, for example, the handle part 11 </ b> G is picked up with one hand, and can be smoothly and quickly lifted with a smaller force than before. Can be opened. Further, when opening, a large force is not applied to the package, and damage to the internal napkin 10 can be prevented. At the same time, the high strength of the package sealing part 26 is ensured, and the cleanliness inside the package 20 is enhanced.

  In order to achieve the functions of the package sealing part 26 and the opening guide part 25, the bonding strength G of the package sealing part 26 is set higher than the peel strength H of the opening guide part 25. The difference in strength (GH) between the bonding strength G of the package sealing portion 26 and the peel strength H of the opening guide portion 25 is preferably 100 g / 10 mm or more from the viewpoint of ease of peeling from the opening guide portion. 300 g / 10 mm or more is more preferable, and 500 g / 10 mm or more is more preferable.

In the package 20 of the present embodiment, as shown in FIG. 1, the opening guide portion 25 is disposed between the package seal portion 26 and the fixing portion (release sheet fixing portion) 15A. Is preferred. The relationship between the fixing portion (release sheet fixing portion) and the opening guide portion here is an arrangement relationship when the package 20 is viewed in plan. Further, this relationship means that in the region 22 including the other end portion 11b, and the fixing portion (for example, the fixing portions 15B and 15C illustrated in FIG. 1A) and the opening guide in the other region. It is not related to the part 25.
Due to the above arrangement relationship, in the region 22 including the other end portion 11b, when the packaging body sealing portion lower portion 11P of the exterior material 11 is pulled up, the remaining fixing portion 11Q of the exterior material 11 becomes difficult to float, and the exterior material The force separating 11 is concentrated on the opening guide portion 25. Due to the concentration of the external force, the entire package is not easily broken, and damage to the internal napkin 10 is prevented. As a result, the package is opened more smoothly and quickly.

  In the region 22 including the other end portion 11b, the fixing portion (release sheet fixing portion) 15 is not lower than the packaging body sealing portion lower portion 11P or the like so as not to hinder the lifting of the packaging body sealing portion lower portion 11P of the exterior material 11. It is preferable that the other end 11b side is not present.

From the viewpoint of the above action, the bonding strength J of the fixing portion 15A is preferably 100 g / 10 mm or more, more preferably 300 g / 10 mm or more, and further preferably 500 g / 10 mm or more.
The bonding strength J of the fixed portion 15A can be measured by the same method as described above (method for measuring the bonding strength G of the package sealing portion 26).

As a forming material and a forming method of the release sheet fixing portion 15, various materials can be used without particular limitation as long as the above-described bonding strength is obtained. For example, a hot melt adhesive coating film is used. As this hot melt adhesive, rubber-based, olefin-based, EVA-based hot melt, or the like can be used. When the fixing portion 15A is formed of a hot melt adhesive, the coating basis weight is preferably 5 g / m ² or more, more preferably 10 g / m ² or more, and more preferably 30 g / m ² or more in order to obtain the above-described bonding strength. Is more preferable. The upper limit is preferably 200 g / ^{m 2} or less, more preferably 100 g / ^{m 2,} more preferably 70 g / ^{m 2} or less.

  Furthermore, in the package 20 of the present embodiment, as shown in FIG. 1, the opening guide portion 25 is preferably disposed in the overlapping region 24 and covered with the exterior material 11 in the first exposed region 21. Thereby, direct exposure to the outside of the opening guide portion 25 is avoided, and contamination of foreign matter such as dust from the slight gap of the opening guide portion 25 when not opened is suppressed. Moreover, even if a part of the opening guide portion 25 is broken by some external force before use, the exterior material 11 in the first exposed region 21 is protected, so that the damage due to foreign matter is kept low. Thereby, the cleanliness inside the package 20 is improved.

As described above, the packaging body 20 according to the present embodiment can smoothly and quickly open the package while ensuring high strength of the packaging body sealing portion.
After the packaging body 20 is opened smoothly and quickly along the opening guide portion 25 as described above, the side sealing portions on both sides in the width direction of the packaging body 20 are further pulled by pulling the handle portion 11G toward the first folding portion L1. 27 and 27 also peel off. That is, the first exposed region 21 fixed by the side sealing portions 27 and 27 is peeled from the region 22 and the central region 23 including the other end portion 11b. Thereby, the 1st exposed area | region 21 is expand | deployed with the one end part 10a side of the napkin 10 folded, and a big opening is formed. Thereafter, the exterior material 11 is peeled off from the napkin 10 together with the release sheet 14, and the napkin 10 is attached to a predetermined position of shorts (not shown) from the part where the release sheet 14 is peeled off. Finally, the exterior material 11 is completely peeled off from the napkin 10 together with the release sheet 14, and the entire region of the shift stopper 13 of the napkin 10 is attached to the shorts.

  The aforementioned relationship between the opening guide 25, the package sealing part 26, the fixing part (release sheet fixing part) 15A, and the length of the handle part 11G are appropriately changed so that the above-described action is suitably expressed. can do. Here, another preferred embodiment (second to fifth embodiments) will be described below with reference to FIGS. In addition, as long as the structure of the package of the absorbent article shown as 1st Embodiment-5th Embodiment has the above-mentioned effect | action, it can mutually combine.

First, as shown in FIG. 4, the packaging body 30 of the second embodiment includes a second folding portion in which the opening guide portion 25 and the fixing portion 15 </ b> A separate the region 22 including the other end portion 11 b from the central region 23. It is arranged closer to L2. That is, the fixing portion 15A and the breakage guiding portion 25 are not present in the overlapping region 24 on the second folding portion L2 side with respect to the package sealing portion 26.
This is a form in which the separation distance M2 between the opening guide portion 25 and the package sealing portion 26 is wider than that of the package 20 of the first embodiment. Such a form is possible as long as the pulling force of the handle portion 11G effectively spreads to the opening guide portion 25 via the package sealing portion 26. This is the case, for example, when the size of the package is sufficiently small (when the length M1 in the folding direction of the package itself is short or the thickness N1 of the package is thin). In this case, the effect of reducing the opening force due to the length of the separation distance M2 is reduced, and the opening can be performed relatively smoothly and quickly.
In such a form, since the opening place is close to the second folding portion L2, when the outer layer material 11 of the side sealing portions 27, 27 is peeled from the second folding portion L1, a large opening is formed. This makes it easier to peel the exterior material 11 from the napkin 10 inside.

Further, as shown in FIG. 5, the packaging body 40 of the third embodiment is one in which the fixing portion 15 </ b> A in the packaging body 30 of the second embodiment is moved closer to the second folding portion L <b> 2 of the central region 23. That is, the fixing portion 15A and the breakage guiding portion 25 are not present in the overlapping region 24 on the second folding portion L2 side with respect to the package sealing portion 26.
Also in this case, the separation distance M2 between the opening guide part 25 and the package sealing part 26 is a form that is wider than the package 20 of the first embodiment. Therefore, as in the second embodiment, it is possible if the pulling force effectively spreads to the opening guide portion 25, such as the size of the package is sufficiently small. Similarly to the second embodiment, the opening after opening becomes large, and the exterior material can be easily peeled off from the napkin 10, which is preferable.
Furthermore, in the packaging body 40 of 3rd Embodiment, the fixing | fixed part 15A in the packaging body 30 has moved toward the 2nd folding part L2 of the center area | region 23, and this expresses the effect which makes it easy to have a release paper after opening. Can do.

Next, as shown in FIG. 6, the packaging body 50 of the fourth embodiment is one in which all of the opening guide portion 25, the packaging body sealing portion 26, and the fixing portion 15 </ b> A are moved closer to the second folding portion L <b> 2. . That is, the fixing portion 15A does not exist in the overlapping region 24 on the second folding portion L2 side than the package sealing portion 26.
In this case, the positional relationships among the unsealing guide part 25, the package sealing part 26, and the fixing part 15A are close to each other as in the first embodiment. Therefore, the lifting force by the handle portion 11G is directly transmitted to the opening guide portion 25, and the opening is smoothly and quickly performed as in the first embodiment. Further, in this case, as in the second and third embodiments, the opening after opening becomes large, and the exterior material can be easily peeled off from the napkin 10, which is preferable.

  Finally, as shown in FIG. 7, in the packaging body 60 of the fifth embodiment, the handle portion 11G (exterior material) of the first exposed portion 21 is disposed beyond the region including the other end portion. In this case, the handle portion 11G can be easily grasped and opened easily. Moreover, since the handle part 11G covers the area | region 22 including the other end part 11b which has the opening guidance | induction part 25 widely on the whole surface, suppression of foreign material mixing is improved.

Furthermore, in each of the above embodiments, another example of the arrangement of the opening guide portion 25 will be described with reference to FIG. The opening guide portion 25 shown in FIG. 8 is in contact with or disposed near the package sealing portion 26. The term “in contact” refers to a state that circumscribes or overlaps the base of the package sealing portion 26, and “near” refers to a position where the distance is 5 mm or less even if separated. Thereby, the pulling-up force via the package sealing part 26 is directly transmitted to the opening guide part 25, and the force concentrates on this part. Thereby, it is preferable that the package is not easily collapsed, and smooth and quick opening is more reliably performed.
Moreover, although not shown, it is also preferable that the opening guide part 25 is arranged in the vicinity of the fixed part 15A. The term “in contact” refers to a state that circumscribes or overlaps the base of the fixed portion 15A, and “near” refers to a position that is 5 mm or less in distance even if separated. Thereby, at the time of separation of the exterior material 11 at the time of opening, there is no play which the fixed part 11Q to which the napkin 10 of the exterior material 11 was fixed floats. Therefore, it is preferable that the fixing portion 11Q is firmly fixed, and the packaging body sealing portion lower portion 11P of the exterior material 11 is separated and opened more smoothly and quickly.
In addition, although not shown, it is also preferable that the opening guide portion 25 is disposed in the vicinity of both the package sealing portion 26 and the fixing portion 15A. That is, the two examples are combined. This “contacting” and “neighboring” are synonymous with those defined in the above two examples. This case is preferable because it has the effects of the above two examples, and can be opened very smoothly and quickly.

Furthermore, in each of the embodiments described above, another aspect of the opening guide portion will be described with reference to FIG. The opening guide portion 25 shown in FIG. 9 is made by making the exterior material weaker than other portions, and the opening guide portion 25 is disposed up to the region where the package sealing portion 26 is disposed. Has been. In other words, the opening guide portion 25 due to weakening is formed from the region 22 including the other end portion 11 b to the lower portion 11 </ b> P of the packaging material sealing portion 11 of the exterior material 11 that overlaps the packaging material sealing portion 26. In other words, the entire weakened region in the direction of the first fold portion L1 and the second fold portion L2 of the weakened region in the package sealing portion lower portion 11P of the exterior material 11 is the opening guide portion 25.
This weakening means a state in which the strength of the member is reduced, for example, a method of providing a plurality of pores in the region, a method of pre-cutting by applying a very strong pressure, or a method of embossing it can. As a configuration, perforations arranged in a line, aggregates of perforations arranged in a line with a predetermined width, cuts that do not lead to cutting in the thickness direction of the exterior material 11 arranged in a line, a predetermined width An assembly of cuts that do not lead to cutting in the thickness direction of the outer packaging material 11 arranged linearly, a groove in which the tensile strength of the outer packaging material 11 is linearly weakened, and a hole in which the tensile strength of the outer packaging material 11 is weakened in a dotted manner The outer packaging material is broken from the opening induction portion 25 by pressing or pulling the outer packaging material 11 on both sides of the opening induction portion 25 with a finger or the like with the opening induction portion 25 as a boundary, such as a linear arrangement with a predetermined width. Thus, any configuration may be used as long as the packaging body is opened and dust or the like does not enter the packaging body and the cleanliness inside the packaging body can be maintained.
The opening guide part 25 can use the shearing force applied to the lower part 11P of the package sealing part, which is the bottom part of the package sealing part 26, and can quickly separate the outer package 11. Moreover, since the spreading of the lifting force concentrates on the opening guide portion 25, the entire package body is not easily broken, and damage to the internal napkin 10 is prevented.

Moreover, in each said embodiment, as FIG. 10 shows, the aspect by which the opening assistance piece 90 is provided in the exterior material 11 of the 1st exposed area | region 21 is also preferable. The opening assisting piece 90 includes an opening base 91 that is bonded and fixed to the first exposed region 21 and a knob 92 that extends from the opening base 91 and is a free end. By having the extended knob portion 92, the exterior material 11 can be easily grasped, and opening can be performed more smoothly and quickly.
Such an opening assisting piece 90 is typically a tab tape. The opening assisting piece 90 made of tab tape is coated with an adhesive on the back surface of the knob portion 92, and when not opened, the adhesive surface is fixed to the exterior member 11 so as to be peelable. Thereby, it will be in the state where the opening guide | induction part 25 was covered, and the cleanliness of the internal napkin 10 can further be improved.

Hereinafter, configurations that can be appropriately applied to each of the above-described embodiments will be described.
On the garment contact surface side of the napkin 10, as described above, the slip stopper 13 is in a detachable fixed state that is weaker than the bonding strength of the release sheet fixing portion 15 </ b> A. It is preferable from the viewpoint of smooth opening of the package that the shift stopper 13 has a fixing strength that prevents the positional displacement of the napkin 10 inside the package even if it can be peeled off. Further, the displacement stopper 13 may not be located at the same position as the release sheet fixing portion 15A as long as the displacement of the napkin 10 is prevented.
As the forming material and the forming method of the misalignment stopping portion 13, various materials can be used without particular limitation as long as the above-described peelable fixing is generated. For example, a hot melt adhesive is used. As this hot melt adhesive, rubber-based, olefin-based, EVA-based and the like can be used. The misalignment stopper 13 may be a so-called solid coating that is continuously applied, such as a planar shape, but in consideration of the adhesive remaining on the shorts in the coated area and the ease of taking out from the exterior material 11 It is preferable that the coating is intermittently applied. Examples of the intermittent application form include a spiral shape, a stripe shape extending in the width direction or the longitudinal direction, an Ω-shape, a dot shape, and the like. The misalignment stopper 13 is positioned substantially in the center in the front-rear left-right direction of the main body portion on the non-skin contact surface side of the napkin 10, the width is 35 mm or more and 70 mm or less, and the length is 65% or more and 95% of the length of the napkin 10. %, And from the viewpoint of preventing warping and slippage of the napkin 10 during use, including all the adhesive portions of the slip stop portion 13 and having a width that is substantially the same as or slightly smaller than the napkin 10 in plan view, Good length.

  The misalignment stopper 13 may exist from the center in the vertical direction of the napkin 10 to the vicinity of the tip of the napkin 10 beyond the first fold L1 and the second fold L2. The release sheet 14 covering the misalignment stopper 13 has a size that can cover the misalignment stopper 13, and is used by being bonded to the exterior material 11 by the release sheet fixing section 15.

The release sheet 14 may be made of the same material as a general napkin release sheet. Specifically, the application amount of glassine paper, polyethylene film, silicone treatment agent is, for example, 0.1 to 5 g. / M ² exfoliated fine paper, composites thereof and the like. This peeling treatment can be performed using a known method. Furthermore, the release sheet 14 may be of any size as long as the outer shape covers the misalignment stopper 13, and the shape is not limited.

  As the material of the exterior material 11, those conventionally used for packaging absorbent articles such as napkins can be used without particular limitation. Resin films such as polypropylene, polyester, polyethylene, polyvinyl alcohol, and the like can be used, and can be appropriately selected and used. In the case of non-woven fabric, composite non-woven fabric (SM, SMS, SMMS, etc.) of spunbonded non-woven fabric (S) and melt-blown non-woven fabric (M) in terms of sheet strength, liquid resistance (resistance to hot melt oozing) and sealing ) Is preferred. From the viewpoint of performing clear printing directly on the exterior material 11, a film material or a laminated structure of the film is also preferably used. In particular, the opening strength of the opening guide portion can be appropriately reduced by using an oriented material whose tearing strength in the continuous direction of the continuous package is lower than that in the width direction, and the ease of opening can be increased.

  The first exposed region 21 is preferably longer in the longitudinal direction of the first exposed region 21 and in the longitudinal direction of the region 22 including the other end 11b. This means that when opening the napkin 10 by breaking and opening the opening guide portion 25 and first expanding the first exposed region 21, the region 22 including the other end portion 11b is expanded. This is because the ease of the unfolding operation increases. If the end 10a of the first exposed area 21 on the first exposed area side of the napkin 10 and the other end 11b are separated from each other by an appropriate distance, it is difficult for interference between the operations of both hands when opening. Therefore, it is preferable. Specifically, the distance is preferably 5 mm or more and 20 mm or less, and more preferably 7 mm or more and 18 mm or less.

  In the napkin 10, the exterior material 11 in the region 22 including the other end portion 11b is folded back to the first exposed region 21 side, and the exterior material end portion 11b is exposed to the outer surface side from the first folded portion L1. 1 (ie, located above the first fold line L1 in FIG. 1B), and the exterior material end 11a in the first exposed region 21 is also exposed to the outer surface side from the first fold L1. The ends are joined together. This configuration is a preferable configuration from the viewpoint of easy sealing by heat sealing.

  When the napkin 10 has a pair of wing portions 5 extending from both side ends in the longitudinal direction, the longitudinal end portions of the wing portions 5 should be folded at the first fold portion L1 or the second fold portion L2. This is because in the folded state, the restoring force to return to the unfolded state is stored in the napkin 10 and the ease of opening is enhanced even if the external force necessary for unfolding is small.

  When the wing portion 5 is provided with a shift stopper (not shown), a separate release sheet for wing is used to protect and cover the shift stopper. In this case, it is preferable that the release sheet for wings is not folded at the first fold portion L1 and the second fold portion L2 from the viewpoint of stably protecting and covering the misalignment hot melt. When the napkin is folded around the longitudinal end of the release sheet for wings, the napkin is more rigid in the folded state, and the shape stability can be improved under unexpected operating loads (packaging and sales of products) before use. Secured.

  In a state where the napkin 10 is folded, it is preferable that one end portion in the longitudinal direction of the release sheet 14 and the other end portion overlap each other. By becoming such a form, in the overlapping part, the rigidity in the folded state of the napkin is increased, and shape stability in an unexpected operation load before use is ensured.

  It is preferable that the release sheet fixing portion 15 be present at a plurality of locations in a form separated from the entire product from the viewpoint of securely bonding the release sheet 14 and the exterior material 11 without wrinkles or sagging. Of the plurality of locations, the adhesive strength of the release sheet fixing portion 15 located closest to the end in the longitudinal direction is preferably higher than other locations. By doing in this way, when opening the opening guide part 25 or when peeling the napkin 10 from the release sheet 14, there is no damage to the members and the napkin 10, and the release sheet 14 can be removed from the exterior material 11. It is preferable from the viewpoint that there is nothing. As a method for increasing the adhesive strength, it is conceivable to increase the coating area. By increasing the application area, the adhesive area between the adhesive and the exterior material increases, and the adhesive strength can be increased.

  For example, a hot melt material is used for the package sealing portion 26, and the hot melt material is preferably colored. By coloring, the exterior material edge part of a 1st exposure area | region can be specified, and there exists an effect that it is easy to appeal to a user that the sealing degree as a product is ensured. There are systems in which ink or pigment is added as the colored hot melt, but a hot melt component that has a large absorption spectrum characteristically in the original visible absorption region may be selected. For example, it is conceivable to use a yellowish hot melt by means such as lowering the hydrogenation rate of a styrene-butadiene-styrene block copolymer which is one main component of the hot melt.

  When the packaging body sealing portion 26 is a hot-melt material, the packaging body sealing portion may have any shape, and is often a straight line (coater coating) having a certain width. It may be a pattern composed of curves, such as coating or Ω coating. A pattern composed of curves is preferable in that it can be efficiently bonded with a small amount.

  The region where the package sealing portion 26 and the side sealing portion 27 overlap has a tendency to extremely increase the sealing strength, and may significantly impair the ease of opening, so that the sealing strength does not increase above a certain level. It is important to apply. For example, the package sealing part 26 is provided so as to avoid the side sealing part 27, and the width of the side sealing part 27 on the packaging sealing part 26 is reduced. By reducing the size of the, a significant increase in sealing strength can be suppressed.

  Moreover, when the package sealing part 26 or the side sealing part 27 is heat-sealed, it is preferable to use a material having a layer structure of two types of resins having different melting points as the forming material of the exterior material 11. As a result, the surface (outer surface) that touches the seal processing equipment is the high melting point layer side, and the surface (inner surface) that the napkin 10 contacts is the low melting point side (that is, the napkin 10 contacts the outer surface of the exterior material 11). By making the melting point higher than the inner side surface, it is possible to ensure seal adhesion by the low melting point layer while suppressing contamination of the seal processing equipment due to material melting, and it is possible to achieve both seal adhesion and processing stability. . By reducing or not providing the thickness of the high melting point layer in the overlapping region 24, it is possible to achieve both further seal adhesion and processing stability.

  Since the edge part of the exterior material 11 in the 1st exposure area | region 21 is a part which it has in the case of opening operation, it is preferable that it is not sealed by the package body sealing part 26 and the side sealing part 27. FIG. As a means for that purpose, the package sealing part 26 is not provided at the end of the exterior material 11, the dimensions of the side sealing part 27 are reduced, and two types of resins having different melting points are layered as the material for forming the exterior material 11. It is preferable from the viewpoint of ease of opening that the structure is not sealed or the sealing strength is weakened by a method such as using a structure and providing or increasing the thickness of the high melting point layer only at the end.

  On the garment contact surface 10s of the napkin 10 (absorbent article), a misalignment preventing portion 13 for fixing the garment is disposed. It is also possible to directly fix the exterior material 11 by the misalignment stopping portion 13 in the fixing portion. In such a form, since the release sheet fixing part 15 can be provided with the function of the release sheet fixing part 15 and the release sheet 14 can be omitted, the material cost and the manufacturing cost can be reduced, and the structure can be simplified.

Although the present invention has been described with respect to a packaging form in which the napkin 10 is folded in three, the present invention can also be applied to a packaged body in which the napkin 10 is folded in four.
As shown in FIG. 11, the packaging body 20 (20b) is of the packaging form in which the packaging body 20 of the first embodiment is folded in the vertical direction. Except for the folding method, it is basically the same as the packaging form of the tri-fold napkin 10 described above. Specifically, the napkin 10 is folded three times by being folded at three locations of the first fold L1, the second fold L2, and the third fold L3 with the wearer contact surface 10sm side inward. ing.
That is, the clothing contact surface 10 sw of the napkin 10 is fixed to the inner surface of the exterior material 11 by the fixing portion 12. The napkin 10 and the release sheet 14 are in a detachable fixed state, and the fixation between the release sheet 14 and the exterior material 11 is a stronger fixed state than the fixation between the napkin 10 and the release sheet 14. A fixed state that is difficult to peel off is preferable.
When the exterior material 11 is folded together with the release sheet 14 and the napkin 10, the exterior material 11 has a size that includes them. In the folded state, the one end portion 11a side of the outer packaging material 11 in the vertical direction extends outward from the one end portion 10a of the sanitary napkin to form an outer packaging material extension region.

  In the package 20b, a region including the one end portion 11a of the exterior material 11 outside the first folding portion L1 forms a first exposed region 21 serving as an outer surface of the package 20. In addition, the overlapping region 24 in this case is, as described above, the portion on the outer surface side of the region 22 including the other end portion 11b of the exterior material 11 and the first exposed region 21 outside the second folding portion L2. Is a region where and overlap. That is, in the region 22 including the other end portion 11b, the region where the region between the second fold portion L2 and the third fold portion L3 overlaps with the first exposed region is the overlap region 24.

  Similarly to the package 20 shown in FIG. 1 and the like, the package 20b is a combination of the package seal portion 26 and the opening guide portion 25, while ensuring high strength of the package seal portion, and opening the package 20b. Can be done smoothly and quickly. In addition, the four-fold form shown in FIG. 11 can be applied to the above-described second to fifth embodiments to obtain the same function and effect.

  The napkin 10 can have the same packaging form regardless of the presence or absence of wings (not shown). Further, in addition to the napkin 10 described above, a urine leakage pad, a panty liner, and the like can be packaged as an absorbent article in an exterior material to have the same packaging form as described above.

A plurality of packages of absorbent articles such as the napkin 10 described above may be connected to form a continuous package that can be separated for each of the packages along the separation guide portion disposed between the packages. it can.
Specifically, as shown in FIG. 12, a plurality of packages are continuously present in the same direction as the disposing direction of the opening guide portion 25. That is, the individual packaging bodies are continuous packaging bodies that are continuously arranged, and the individual packaging bodies 20 can be freely separated by the separation guide portions 28 disposed on the side sealing portions 27.
In order to separate individual packages from the continuous package, they are separated by a normal separating operation. For example, it is possible to detach by holding both sides of the detachment guide part 28 with fingers and pulling in a direction perpendicular to the detachment guide part 28 or tearing it off at the separation guide part.
As described above, since the separation guide portion 28 is arranged in a direction perpendicular to the arrangement direction of the opening guide portion 25, the separation guide portion 28 is separated without being affected by the tensile force required when the opening guide portion 25 is opened. The required tensile force can be designed.
In addition, since the separation guide portion 28 is arranged in a direction perpendicular to the arrangement direction of the opening guide portion 25, the tensile force applied when the individual package body 20 is separated from the separation guide portion 28 is different from that of the individual package body 20. Since it is different from the direction of the pulling force that opens the opening guide part 25, the opening guide part 25 is difficult to break at the time of separation.

  Arbitrary printing is preferably performed on the exterior packaging material 11 of the continuous package in terms of aesthetics and recognition of product features. Furthermore, it is preferable on manufacture that the printing pattern in the continuous direction of a continuous package has a certain periodicity. In the continuous direction of the continuous package, the shortest length from the printing position until the same printing appears is called a printing pitch. When the printing pitch matches the interval between the napkin 10 and another adjacent napkin 10 in the continuous direction of the continuous package, it is preferable that the same pattern printing can be performed for each napkin 10. In this case, it is preferable to provide a rectangular black mark called an eye mark that serves as a mark for synchronizing the printing pitch and the napkin interval. When the interval between the napkin 10 and another adjacent napkin 10 does not match the printing pitch, a printing pattern appears at random in the continuous direction of the continuous package, instead of having to apply an eye mark. In this case, the printing pitch is made smaller than the interval between the napkin 10 and another adjacent napkin 10. Accordingly, it is preferable in that one or more pieces of all information existing in the printing pitch can be always described per one napkin 10.

  However, different information can be described in two or more napkins 10 adjacent to each other by setting the printing pitch to be twice or more larger than the interval between the napkin 10 and another adjacent napkin 10. By doing so, it is possible to enjoy the change of the print pattern when purchasing the product, which is preferable from the viewpoint of palatability.

  A separation guide 28 that is different from the opening purpose is used so that each napkin 10 can be used after tearing off each individual package 20 between the napkin 10 of the continuous package and another adjacent napkin 10. It has. In the form of the separation guide portion 28, the perforations arranged linearly, the aggregates of the perforations arranged linearly with a predetermined width, and the linear arrangement, like the opening guide portion 25 described above. Breaks that do not lead to cutting in the thickness direction of the exterior material 11, aggregates of cuts that do not lead to cutting in the thickness direction of the exterior material 11 arranged in a line with a predetermined width, and weaken the tensile strength of the exterior material 11 linearly For example, an assembly of holes, in which the tensile strength of the exterior material 11 is weakened in a dotted shape, is arranged in a line with a predetermined width, etc. Any configuration may be employed as long as the exterior material 11 can be separated from the portion 28 by being broken, and the transport is a physical property that is not separated by an operation load assumed at the time of display at a sales place. However, in the case of continuous wrapping, when the detachment induction part is folded and stored in an accordion shape, or when it is folded at the detachment induction part and hung on a string or bar stretched horizontally, the separation induction part From the viewpoint of being easily maintained in a broken state, it is preferable that the end portion of the separation guide portion is notched or only partially cut.
