Description

The present invention relates to a package absorbent article.

Absorbent items such as sanitary napkins, incontinence pads, and pantyliners are generally provided wrapped in wrapping sheets for hygiene and for convenience of portability. is there. As such a packaged absorbent article, that is, a package absorbent article, for example, an elongated packaging sheet is folded in the longitudinal direction together with the absorbent article, and both edges of the packaging sheet in the width direction are joined by a heat seal or the like. In many cases, the seal portion is formed.

When opening such a packaging absorbent article, the user needs to peel off the packaging sheets at the sealing portions of both edges from each other. At that time, a sound of the packaging sheets being peeled off (peeling sound) is generated at the seal portion, and such a sound may be unpleasant depending on the user. Therefore, a device for reducing the peeling sound is being studied.

For example, Patent Document 1 describes a configuration in which a weak joint portion 41 and a strong joint portion 42 are formed in this order from the central portion side to the outer side of the individual body 1 in the seal portion 4. There is. It is described that this configuration facilitates opening and reduces peeling noise.

However, the configuration disclosed in Patent Document 1 does not reduce the region itself where the sheet is peeled off. Therefore, the peeling sound may not be sufficiently reduced depending on the situation at the time of opening, the peeling method of the user, and the like.

Japanese Patent No. 4275105

One aspect of the present invention provides a package absorbent article in which the peeling sound at the time of opening is reduced and the discomfort due to the peeling sound is sufficiently reduced.

A first aspect of the present invention is a packaging absorbent article including a packaging sheet and an absorbent article packaged by the packaging sheet, wherein the packaging sheet is folded longitudinally along at least one fold line. , The sealing portion is formed by sealing at the edge portion in the width direction orthogonal to the longitudinal direction, and at a position separated from the folding line by a predetermined distance, in the longitudinal direction of peeling of the sealed packaging sheet. A peeling prevention part is formed to prevent the progress of the product.

According to the first aspect, a peeling suppressing portion for suppressing the progress of peeling of the sealed packaging sheet in the longitudinal direction is formed. Therefore, when the peeling of the sealed packaging sheet is progressing when the package absorbent article is opened, the progress of peeling can be stopped at the position where the peeling suppressing portion is formed. As a result, the length of the portion of the seal portion of the package-absorbent article from which the packaging sheet is peeled off is shortened, and the portion where the peeling sound is generated is reduced, so that the peeling sound can be reduced more effectively.

In a second aspect of the present invention, the packaging sheet includes a first region including one end in the longitudinal direction folded at the first fold line and the other end in the longitudinal direction folded at the second fold line. It has a second region and is folded so that the first region overlaps the second region, and the sealing portion includes a thin zone having the smallest number of sealed packaging sheets and the said sealing portion. The thin zone includes a thick zone in which the number of sealed packaging sheets is larger than that of the thin zone, and the peeling suppressing portion is formed in the thin zone.

According to the second aspect, even if the packaging sheet is a packaged absorbent article in which the absorbent article is packaged by folding at least in three, the absorbent article is peeled off in the middle of the sealing portion without hindering the removal of the absorbent article at the time of opening. The deterrent part can suppress the progress of peeling.

In the third aspect of the present invention, the thin zone includes a first thin zone on the first fold line side and a second thin zone on the second fold line side, and the peeling suppressing portion is viewed in a plan view. The first peeling suppressing portion formed in the first thin zone and the second peeling suppressing portion formed in the second thin zone are included.

According to the third aspect, thin zones in which the minimum number of packaging sheets are laminated and sealed are present on both the first fold line side and the second fold line side of the absorbent article, and are peeled off in each thin zone. A deterrent part is formed. At the time of opening, usually, a step of rolling and peeling off the first region of the packaging sheet and then a step of rolling and peeling off the second region are performed, but the length of time during which the peeling sound is generated can be reduced in both steps. ..

In the fourth aspect of the present invention, the peeling suppressing portion is formed by reducing the width of the sealing portion.

According to the fourth aspect, by reducing the width of the seal portion, a portion where the total length of the seal portions along the longitudinal direction is reduced is formed. Such a portion is a portion where the pressure of the roller or the like is concentrated at the time of forming the seal portion and the joint strength is increased, and can act as a peeling suppressing portion. Further, when the packaging sheet is peeled off, the peeling proceeds in the longitudinal direction, but the progress of the peeling is at least partially interrupted at the portion where the width of the seal is reduced. Relatively large peel resistance can occur due to the resumption of the interrupted peel progress. Therefore, the effect of suppressing the progress of peeling of the peeling suppressing portion can be enhanced.

In the fifth aspect of the present invention, in the peeling suppressing portion, the contour line on the inner side in the width direction of the sealing portion includes a line in which the central side in the width direction is inclined forward in the traveling direction of the peeling with respect to the width direction. ..

At the time of opening, for example, in the step of rolling and peeling off the first region of the packaging sheet, the direction in which the peeling proceeds (peeling progress direction) is the longitudinal direction with the direction toward the first folding line as the front. At this time, since the user peels off the first region by holding the vicinity of the center in the width direction, the peeling precedes on the center side in the width direction of the seal portion, and the first region is a portion that has not been peeled off and a portion that has already been peeled off. The boundary line of is not parallel to the width direction, but tends to be a line in which the center side in the width direction is inclined forward in the peeling progress direction with respect to the width direction.

According to the fifth aspect, the contour line on the inner side in the width direction of the seal portion includes a line in which the center side in the width direction is inclined forward in the peeling progress direction with respect to the width direction. If the outline of the seal portion is along the above-mentioned boundary line (the boundary line between the portion that has not been peeled off and the portion that has already been peeled off), it is interrupted at least partially at the position where the width of the seal portion is reduced. Even if an attempt is made to resume the progress of peeling, the progress of peeling is suppressed due to the large peeling resistance. Combined with the reduction in the width of the seal portion, the action of the peel prevention portion that suppresses the progress of peeling can be further increased.

In the sixth aspect of the present invention, the seal portion is discontinuous behind the peeling prevention portion in the direction of progress of the peeling, and an absent portion of the seal portion is formed. Includes a line whose contour is inclined with respect to the width direction.

According to the sixth aspect, the progress of peeling may be interrupted by the discontinuity of the sealing portion. Then, since a relatively large peeling resistance is generated in order to restart the progress of the peeling after the interruption, the action of suppressing the peeling progress of the peeling suppressing portion becomes large. Further, since the contour of the non-existent portion of the seal portion includes a line inclined with respect to the width direction, it is difficult for dust, dust, etc. to enter from the outside of the package absorbent article through the edge portion. It is possible to keep the package absorbent article hygienic while improving the action of the peeling prevention portion.

In the seventh aspect of the present invention, the peeling suppressing portion includes a portion formed so as not to be peeling.

According to the seventh aspect, even when the user puts a lot of effort into opening the package, the peeling prevention portion can more reliably exert the peeling progress suppressing action. Therefore, the length of the portion of the seal portion from which the packaging sheet is peeled off can be shortened more reliably, and the peeling noise can be reduced.

In an eighth aspect of the present invention, the peeling restraint includes a notch or notch at the edge.

According to the eighth aspect, since the material itself at the edge of the packaging sheet on which the seal portion is formed becomes discontinuous at least partially, the peeling progress suppressing action of the peeling suppressing portion can be more reliably exerted. Can be done. Therefore, the length of the portion of the seal portion from which the packaging sheet is peeled off can be shortened more reliably, and the peeling noise can be reduced.

According to one aspect of the present invention, there is provided a package absorbent article in which the peeling sound at the time of opening is reduced and the discomfort due to the peeling sound is sufficiently reduced.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, unless otherwise specified, the same or corresponding configurations may be designated by the same reference numerals and the description thereof may be omitted. In addition, the drawings are schematic to help the understanding of the invention.

(Packaging absorbent goods)
FIG. 1 shows a package absorbent article 100 according to one embodiment of the present invention. Further, FIG. 2A shows a cross-sectional view taken along the line Ia-Ia of FIG. 1, and FIG. 2B shows a cross-sectional view taken along the line Ib-Ib of FIG.

As shown in FIGS. 1 and 2, the package absorbent article 100 includes a packaging sheet 10 and an absorbent article 1 packaged by the packaging sheet 10. In other words, the package absorbent article 100 is an individual package containing one absorbent article 1 inside. The packaging sheet 10 may have an elongated shape, for example, a rectangular shape, an oblong shape, or the like. The dimensions of the packaging sheet 10 depend on the size and shape of the absorbent article 1 to be packaged. For example, when the packaging sheet 10 is unfolded, the length in the longitudinal direction D1 is 120 to 500 mm and the length in the width direction D2 (simply). (Sometimes referred to as width) can be 75 to 180 mm. Further, the length of the package absorbent article 100 in the folded state in the longitudinal direction D1 may be 50 to 160 mm.

For the packaging sheet 10, a material such as a polyolefin film such as polypropylene or polyethylene, a single-layer or multi-layer resin film such as polyester or polyvinyl alcohol, a non-woven fabric, or a laminated non-woven fabric in which a non-woven fabric and a resin film are laminated may be used. it can. Of these, a resin film is preferable from the viewpoint of improving design. This is because the color is good and the printing can be sharp. Further, when the resin film is used, the sheet surface becomes flat, so that the bonding strength between the sheets at the bonding portion can be made uniform. On the other hand, from the viewpoint of improving the texture and softness, a non-woven fabric or the like is preferable.

The packaging absorbent article 100 is obtained by placing the absorbent article 1 on the expanded packaging sheet 10 and folding the area including the end portion of the packaging sheet 10 toward the side on which the absorbent article 1 is placed. Can be done. In the form of FIGS. 1 and 2, the packaging sheet 10 is wound in the longitudinal direction D1 of the packaging sheet 10 and folded in three together with the absorbent article 1 placed on the packaging sheet 10. More specifically, the first region R1 including one end 11 of the longitudinal direction D1 of the packaging sheet 10 is folded at the first folding line FL1, and the second region R2 including the other end 12 of the longitudinal direction D1 of the packaging sheet 10 is folded. It is folded at the second folding line FL2. Then, at the time of folding, the first region R1 is arranged so as to overlap the second region R2. It is preferable that the other end 12 of the packaging sheet 10 included in the second region R2 to be folded first does not reach the first folding line FL1 in which the first region R1 is folded. Further, one end 11 of the packaging sheet 10 included in the first region R1 which is folded so as to overlap the second region R2 after the second region R2 is folded has a second folding line FL2 in which the second region R2 is folded. It is preferable that the region does not exceed the second region R2. In this embodiment, the region between the first region R1 and the second region R2 is referred to as the third region R3.

After the packaging sheet 10 is rolled and folded in three as described above, it is preferable that the tab tape 15 is attached so as to cover the first region R1 and the second region R2 as shown in FIG. More specifically, the tab tape 15 is arranged in the first region R1 and the second region R2 so as to straddle the free end portion of the first region R1 arranged on the outside, that is, one end 11 of the packaging sheet 10. Further, the tab tape 15 is preferably arranged at the center of the width direction D2 of the packaging sheet 10 which is a direction orthogonal to the longitudinal direction D1 of the packaging sheet 10. Since the tab tape 15 is provided, when the package absorbent article 100 is opened, the user can lift the first region R1 by holding the tab tape 15, so that the opening becomes easier.

In the package absorbent article 100, in the state of being rolled and folded in three as described above, both edge portions in the width direction D2 are further joined to form the sealing portions 20 and 20. The packaging sheets laminated and joined in the sealing portions 20 and 20 can be peeled off from each other. Here, in the present specification, "peelable" means that when the user opens the package-absorbent article by a usual method, the joint breakage occurs at the seal portion, that is, the bonded packaging sheets are peeled off from each other. It means that it has become. On the other hand, "non-peelable" means that when the user opens the packageable absorbent article by a normal method, the joint is not released at the seal portion, that is, the bonded packaging sheets are not peeled off and the joint is maintained. It means that it has become.

The sealing portion 20 includes a joint portion in which the packaging sheets are integrated by applying pressure and / or heat from one side or both sides of the plurality of stacked packaging sheets. The sealing portion is preferably formed by a sealing method such as heat sealing or ultrasonic sealing, and particularly preferably formed by heat sealing.

The absorbent article 1 is housed in the package absorbent article 100 over the longitudinal direction D1, but is housed so as not to overlap both edges in the width direction D2 as shown in FIGS. 1 and 2 (b). Has been done. That is, the absorbent article 1 does not exist between the end portion in the width direction D2 and the position separated by a predetermined length. Therefore, at the edge of the packaging absorbent article 100, the plurality of packaging sheets 10 are directly laminated and joined (FIG. 2B).

Each seal portion 20 may be preferably formed within a range of 25 mm from the end of the packaging sheet 10 in the width direction D2. Further, each seal portion 20 may be formed over the entire or part of the above range, and can be formed, for example, in the above range in the form of one or more strips having a width of 5 mm or more and less than 25 mm. In the region having a predetermined width from the end of the packaging sheet 10 in the width direction D2, there may be a portion where the joint portion does not exist. Further, the width of each seal portion 20 is not constant over the longitudinal direction D1 as a whole, and may vary slightly.

Further, the joint portion may be continuously formed over the entire seal portion 20, that is, the area of the seal portion 20 may be substantially equal to the area of the joint portion. Further, the seal portion 20 may be an aggregate of a plurality of joint portions microscopically, that is, the total area of the joint portions may be smaller than the area of the seal portion 20. In the latter case, the total area of the joint portion with respect to the area of the seal portion 20 is preferably 10% or more. Further, when the seal portion 20 is an aggregate of a plurality of joint portions, the distance between the joint portions can be preferably less than 1.5 mm, more preferably less than 1 mm in a plan view.

As described above, since the absorbent article 1 does not exist at the edge of the packaging absorbent article 100, the packaging sheets are directly laminated and joined to each other in the sealing portions 20 and 20. Here, in the seal portions 20 and 20, as shown in FIG. 2B, the number of stacked packaging sheets differs in the longitudinal direction D1. More specifically, the sealing portion 20 may have a thin zone having a minimum number of bonded packaging sheets and a thick zone having a larger number of bonded packaging sheets than the thin zone. For example, the seal portion 20 may have a thin zone in which two packaging sheets are laminated and joined, and a thick zone in which three or more packaging sheets are laminated and joined. Although it depends on the method of forming the seal portion 20, the smaller the number of laminated packaging sheets in the seal portion 20, the more easily it is affected by pressure and / or heat in the sealing process. Bonding strength (peeling resistance) tends to increase. In particular, when the sealing portion 20 is formed by welding the packaging sheets to each other by using heat to melt the packaging sheets as in heat sealing, the greater the influence of heat applied, the greater the influence of the heat applied to the laminated packaging sheets. The joint strength is higher in the region where the number of sheets is small.

In the illustrated form, the thin zone is a zone in which two packaging sheets are laminated and joined, and the first thin zone Z _2a existing on the side of the first folding line FL1 of the first region R1 and the second thin zone Z 2a. It includes a _{second thin zone Z 2b} existing on the side of the second folding line FL2 of the region R2. Further, between the first thin zone Z _2a and the second thin zone Z _{2b , a thick zone Z 3} in which three packaging sheets are laminated and joined is formed. In the first thin zone Z _2a , the third region R3 and the first region R1 of the packaging sheet 10 are joined, and in the second thin zone Z _2b , the third region R3 and the second region R2 of the packaging sheet 10 are joined. There are joined, the thickness zone Z _3, the third region R3, the second region R2, and the first region R1 of the packaging sheet 10 is bonded stacked in this order. When the edge of the package absorbent article 100 is sealed under the same conditions (temperature, pressure, etc.) over the longitudinal direction D1, the _{sealing strength in the first thin zone Z 2a} and the second thin zone Z _2b is generally the thick zone. greater than the seal strength in the Z _3.

When attempting to open the packaging absorbent article 100 as shown in FIGS. 1 and 2, the user first holds the free end portion (one end 11 of the packaging sheet 10) of the first region R1 and the first folding line FL1. It opens to the side and the first region R1 is peeled off (first step). At that time, the peeling of the first region R1 in the seal portions 20 and 20 proceeds toward the first folding line FL1 side, that is, in the direction of the arrow A1 in FIG. Then, after the first region R1 is opened, the absorbent article 1 that opens or appears toward the second folding line FL2 by holding the free end portion (the other end 12 of the packaging sheet 10) of the second region R2. The second region R2 is peeled off from the third region R3 by holding the end portion and lifting it toward the second folding line FL2 side together with the second region R2 (second step). At that time, the peeling of the second region R2 in the seal portions 20 and 20 proceeds toward the second folding line FL2 side, that is, in the direction of the arrow A2 in FIG. In both of these first step and the second step at the time of opening, the packaging sheets sealed at the sealing portions 20 and 20 are peeled off from each other, and a peeling sound is generated at that time.

This embodiment effectively reduces the peeling noise as described above, and reduces such peeling noise by forming a peeling suppressing portion that suppresses the progress of peeling in the seal portion 20. Is. Hereinafter, the configuration of the peeling prevention unit will be described in detail.

(First Embodiment)
In this embodiment, as shown in FIG. 1, in the first thin zone Z _2a and the second thin zone Z _2b of each sealing portion 20, a peeling suppressing portion for suppressing the progress of peeling of the packaging sheet 10 is formed. Specifically, as shown in FIG. 1, a first peeling suppressing portion 31 is formed in _{the first thin zone Z 2a} for each of the sealing portions 20 and 20 formed on both edges of the package absorbent article 1. A second peeling suppressing portion 32 is formed in the second thin zone Z _2b (each is a cross-hatched portion in FIG. 1). However, as shown in FIG. 1, the peeling suppressing portion _{may be formed not only in both the first thin zone Z 2a} and the second thin zone Z _2b , but only in one of them. That is, any one of the first peeling suppressing section 31 and 31 and the second peeling suppressing section 32 and 32 shown in FIG. 1 can be omitted.

The form of the first peeling suppressing unit 31, 31 and the second peeling suppressing unit 32, 32 (they may be collectively referred to as the peeling suppressing unit 30) is not particularly limited as long as it can suppress the progress of peeling of the packaging sheet. .. In the form shown in FIG. 1, the peeling suppressing portion 30 is formed by reducing the width of the sealing portion 20.

For example, in the case of a heat seal, the seal portion can be formed by using a pair of rollers and passing the seal portion between the two rollers while applying pressure. For example, the packaging sheet is sandwiched and passed between a roller having a convex portion corresponding to the joint portion in the seal portion and a flat roller while being pressed together with the absorbent article 1 in a folded state. In that case, in general, the direction in which the packaging sheet folded together with the absorbent article is conveyed is the width direction of the packaging sheet (D2 in FIG. 1), and the axial direction of the rollers is the longitudinal direction of the packaging sheet (D1 in FIG. 1). It becomes. In that case, a constant force is continuously applied by the roller, but the pressing force (linear pressure) per unit length applied from the roller to the packaging sheet is not always constant depending on the design of the roller convex portion corresponding to the seal portion. is not it. At a position where the total length of the seal portion 20 (or the joint portion included in the seal portion 20) along the longitudinal direction D1 is large, the roller force is dispersed, the linear pressure becomes small, and the joint per unit length is joined. The strength (peeling strength) tends to decrease. On the other hand, at a position where the total length of the seal portion 20 (or the joint portion included in the seal portion 20) along the longitudinal direction D1 is small, the roller force is concentrated, the linear pressure increases, and the unit length is increased. Bonding strength (peeling strength) tends to increase.

When there is a portion where the width of the seal portion 20 is reduced as shown in FIG. 1, a position where the total length of the seal portions 20 along the longitudinal direction D1 is small is formed. More specifically, the illustrated seal portion 20 has a broken portion inside the width direction D2 when viewed along the longitudinal direction D1, and the portion has a length along the longitudinal direction D1 of the seal portion 20. The total is smaller than the outer part of D2 in the width direction. Therefore, in the illustrated form, the joint strength of the seal portion 20 can be increased in the portion inside the width direction D2 of the seal portion 20.

Here, the portion inside the width direction D2 of the seal portion 20 having the increased joint strength is _{formed in the thin zones Z 2a} and Z _2b and the thick zone Z ₃ , but as described above, the joint strength of the seal portion is increased. Is originally large in the _{thin zone Z 2a} where the number of laminated sheets is smaller. Therefore, among the portions inside the width direction D2 in which the total length of the seal portion 20 along the longitudinal direction D1 is small, the portions in the thin zones Z _2a and Z _2b (cross-hatched portions in FIG. 1) are particularly The action of suppressing the progress of peeling can be sufficiently exerted, and this portion becomes the peeling suppressing portion 30.

Further, in the portion where the width is reduced, the progress of peeling may be partially interrupted when viewed in the longitudinal direction D1. Then, a relatively large peeling resistance is partially generated to resume the progress of the interrupted peeling. This also enhances the peeling progress suppressing action of the peeling suppressing portion 30 formed in the thin zones Z _2a and Z _2b.

In this way, the peeling suppressing unit 30 suppresses _{the progress of the peeling in the thin zones Z 2a} and Z _2b , so that the peeling in the first step is less likely to proceed forward in the peeling progress direction than the peeling suppressing unit 30. Or it does not proceed. Then, the portion where the packaging sheet is peeled off at the time of opening becomes a part of the seal portion 20 instead of the entire seal portion 20. For example, the presence of the first peeling suppressing portion 31 formed in the first thin zone Z _2a makes it difficult or impossible for the peeling in the first step to proceed in the peeling progress direction A1. Therefore, the portion packaging sheet is peeled off of the sealing portion 20 can be a portion of the thickness zone Z ₃ only, or a thickness zones Z ₃ and first thin zone Z _2a. That is, the packaging sheet is not peeled off in the whole or a part of the first thin zone Z _{2a, and the peeling sound is not generated.}

Therefore, in the first step of peeling off the first region R1, the length of the portion of the seal portion 20 where the packaging sheet is peeled off is larger than that of the conventional package absorbent article in which the first peeling suppressing portion 31 is not formed. It becomes shorter and the part to be peeled off is reduced. As a result, the portion where the peeling sound is generated is reduced, and the peeling sound can be effectively reduced.

The second peeling suppressing unit 32 formed in the second thin zone Z _2b can also operate in the same manner as the first peeling suppressing unit 31. That is, the progress of the peeling in the second step becomes more difficult or does not proceed in the front of the peeling progress direction A2 than the second peeling suppressing portion 32. Then, the portion packaging sheet is peeled off upon opening can be a portion of the thickness zone Z ₃ only, or a thickness zones Z ₃ and second thin zone Z _2b. Therefore, even in the second step, the length of the portion of the seal portion 20 where the packaging sheet is peeled off is shorter than that of the conventional packaging absorbent article in which the second peeling suppressing portion 32 is not formed, and the packaging sheet is peeled off. The part to be used is reduced. As a result, the portion where the peeling sound is generated is reduced, and the peeling sound can be effectively reduced.

Further, the peeling suppressing portion 30 of the present embodiment formed by reducing the width can be relatively easily manufactured by changing the two-dimensional design of the sealing portion 20 or the like.

Further, by having the peeling suppressing portion 30, a portion of the sealing portion 20 that is left without being peeled off from each other is generated at the time of opening, so that the remaining portion becomes a bag shape. _{For example, when the seal portion 20 is left in the whole or a part of the first thin zone Z 2a} by the first peeling suppressing portion 31, the first region R1 and the third region R3 remain joined at the edge portion. Since the bag-shaped portion is formed by the first region R1 and the third region R3, the used absorbent article can be accommodated in the bag-shaped portion when the used absorbent article is discarded. Even if the entire used absorbent article cannot be stored in the bag-shaped part, a part of the used absorbent article can be inserted into the bag-shaped portion, which makes it easier to wrap it in a wrapping sheet and facilitate the disposal operation. ..

Subsequently, with reference to FIG. 3, the peeling prevention unit 30 according to the first embodiment will be described in more detail. For example, FIG. 3A is an enlarged view of a portion II of FIG. 1, that is, an enlarged view of a first peeling suppressing portion 31 formed in _{the first thin zone Z 2a.} In FIG. 3, one of the first peeling suppressing portions 31 (the peeling suppressing portion on the upper left in FIG. 1) will be described as an example, but the other of the first peeling suppressing portions 31 and the second thin zone Z _2b are formed. The configuration and function of the second peeling suppression unit 32 are the same.

As shown in FIG. 3A and as described above, the first peeling suppressing portion 31 is a portion inside the sealing portion 20 in the width direction D2 in _{the first thin zone Z 2a.} In this way, the inner edge of the seal portion 20 extending in the longitudinal direction D1 in a strip shape has a recess, so that a portion having a small total length of the seal portions 20 along the longitudinal direction D1 is formed. The first peeling suppressing portion 31 is formed.

In the first peeling suppressing portion 31, the contour line inside the width direction D2 of the sealing portion 20 may have a predetermined inclined line 31a as shown in FIG. 3A. The inclined line 31a may be a line in which the central side of the width direction D2 is inclined forward of the peeling traveling direction A1 with respect to the width direction D2.

In the first step at the time of opening (the step of rolling and peeling off the first region R1 of the packaging sheet), the peeling progress direction A1 is the longitudinal direction D1 with the direction toward the first folding line FL1 as the front. At this time, since the user peels off the first region R1 while holding the vicinity of the center of the width direction D2, the peeling precedes on the width direction D2 center side of the seal portion, and the first region R1 is already peeled off from the portion that has not been peeled off. The boundary line B (FIG. 3A) with the formed portion is not parallel to the width direction, and tends to be a line in which the center side in the width direction D2 is inclined forward in the peeling progress direction A1 with respect to the width direction D2. ..

As in this embodiment, if the contour line of the seal portion 20 has a recess and the seal portion 20 is not continuous in the longitudinal direction D1, the peeling progress in the longitudinal direction D1 is interrupted at least partially at that position. Will be done. Then, when the progress of peeling is restarted after the interruption, a relatively large peeling resistance is generated, and it becomes difficult to peel the packaging sheets 10 from each other. At that time, if the contour line of the seal portion 20 is along the boundary line B between the portion where the first region R1 has not been peeled off and the portion where the first region R1 has already been peeled off, the packaging sheets 10 are more difficult to peel off. Therefore, as in the present embodiment, if the contour line of the seal portion 20 has an inclined line 31a along the boundary line B as shown in FIG. 3A in the first peeling suppressing portion 31, the first peeling suppressing portion 31 The action of suppressing the progress of peeling of 31 can be further improved.

The inclination angle α of the inclination line 31a with respect to the width direction D2 is preferably 30 to 70 °, more preferably 35 to 60 °.

3 (b) to 3 (f) show a modified example of the first peeling suppressing unit 31. FIG. 3B shows an example in which the shape and size of the concave portion formed in the seal portion 20 are the same as those shown in FIG. 3A, but the position of the concave portion is deviated to the peeling progress direction A1 side. Is shown.

In the example of FIG. 3B, the bottom of the recess is formed so as to be in _{the first thin zone Z 2a.} As described above, the position where the concave portion of the contour line of the seal portion 20 is formed is not limited. Therefore, the entire recess may be formed so as to be in the first thin zone Z _2a.

In the examples of FIGS. 1 and 3 (a) and 3 (b), the shape of the concave portion of the contour line of the seal portion 20 provided for forming the first peeling suppressing portion 31 is such that the upper bottom is the seal portion 20. Although it is a trapezoid facing the inside, the shape of the concave portion is not limited to the trapezoid, and may be a trapezoid in the opposite direction, a polygon other than the trapezoid, a shape other than the polygon, and the like.

For example, as shown in FIG. 3C, the recess formed in the seal portion 20 is a triangle whose apex faces the inside of the seal portion 20, and the width of the seal portion 20 formed by the recess is small. The portion that is formed can be used as the first peeling suppressing unit 31. The concave triangle of this example is formed so that the apex is on the boundary between _{the first thin zone Z 2a} and the thick zone Z _3. Also in this example shown in FIG. 3C, the contour line of the seal portion 20 in the first peeling suppression portion 31 may have a diagonal line 31a having an inclination angle α with respect to the width direction D2. Further, if the first peeling suppressing portion 31 is _{formed in the first thin zone Z 2a} , the position of the recess of the sealing portion 20 is not limited to the one shown in the drawing.

Further, as shown in FIG. 3D, the recess formed in the seal portion 20 may be a partial circle, specifically a semicircle. Further, as shown in FIGS. 3 (e) and 3 (f), it may be a parallelogram.

In FIG. 3E, the first peeling suppressing unit 31 has a diagonal line 31a having an inclination angle α with respect to the width direction D2. Therefore, the effect of suppressing peeling in _{the thin zone Z 2a} of the first peeling suppressing unit 31 can be further enhanced. As shown in FIG. 3E, the recess of the seal portion 20 may be formed at a position at a distance from the boundary between _{the first thin zone Z 2a} and the thick zone Z _3.

FIG. 4 shows yet another modification of the first embodiment. FIG. 4 is a diagram showing a left side portion of the package absorbent article 100 shown in FIG. 1, and shows a first peeling suppressing unit 31 and a second peeling suppressing unit 32. In the example shown in FIG. 4, the peeling suppressing portion 30 is formed over the entire thin zone. More specifically, the first peeling suppressing portion 31 is _{formed over the entire first thin zone Z 2a} , and the second peeling suppressing portion 32 is formed over the entire _{second thin zone Z 2b.} As a result, even if the user pulls the packaging sheet strongly at the time of opening, it becomes easy to maintain the joining of _{the first thin zone Z 2a in} the first step and the joining of the second thin zone Z _{2b in the second step.}

In the example shown in FIG. 4A, a recess is formed in the seal portion 20 _{across the boundary between the first thin zone Z 2a} and the thick zone Z _{3, and the seal portion 20 covers the entire first thin zone Z 2a.} The width of the is gradually narrowed. Therefore, in the portion inside the width direction D2, the total length of the seal portions 20 along the longitudinal direction D1 is smaller than the portion outside the width direction D2. Since such a portion is formed with a high linear pressure, the joint strength is increased.

In the example shown in FIG. 4B, the center of the seal portion 20 in the width direction D2 is the same in the thin zones Z _2a and Z _2b and the thick zone Z ₃ , but in the thin zones Z _2a and Z _2b , the seal is formed. The width of the portion 20 is reduced from both sides in the width direction D2. Then, in the illustrated example, a portion where the width of the seal portion 20 gradually decreases toward the end portion in the longitudinal direction D1 is formed at a position beyond the _{thick zone Z 3} toward the thin zones Z _2a and Z _2b. .. As a result, in the thin zones Z _2a and Z _2b , a portion where the total length of the seal portion 20 along the longitudinal direction D1 is small is formed, and in such a portion, the linear pressure at the time of forming the seal portion is high. The joint strength is high, and it can play an action of suppressing the progress of peeling.

In the above-described form (FIGS. 1 to 4), the width of the seal portion 20 reduced due to the formation of the first peeling suppression portion 31 is the width of the seal portion 20 at the position where the width is not reduced. On the other hand, it can be preferably 20 to 80%, more preferably 30 to 70%.

FIG. 5 shows yet another modification of the peeling prevention unit 30 in the first embodiment. 5 is also a view showing the left side portion of the package absorbent article 100 shown in FIG. 1, as in FIG. 4, and shows the first peeling suppressing unit 31 and the second peeling suppressing unit 32. Also in the example of FIG. 5, the peeling suppressing unit 30 (the first peeling suppressing unit 31 and the second peeling suppressing unit 32) is formed by reducing the width, but there is a position where the width is set to zero, that is, , The seal portion 20 is different from the other first embodiment (FIGS. 1 to 4) described above in that the seal portion 20 is discontinuous in the longitudinal direction D1.

In the example of FIG. 5A, the discontinuous portion of the seal portion 20 (the non-existent portion of the seal portion 20) is _{near the boundary between the thick zone Z 3} and the first thin zone Z _2a, and is inside the width direction D2. It has a strip shape that is inclined in the direction approaching the first folding line FL1. At the time of opening, for example, in the first step of peeling off the first region R1, the user advances the peeling operation toward the first folding line FL1 in the peeling progress direction A1, but the peeling of the first region R1. Is interrupted at the discontinuous portion of the seal portion 20. Then, when the progress of the peeling is to be restarted, a particularly large peeling resistance is generated, so that the action of suppressing the progress of the peeling at the peeling suppressing unit 30 can be further improved.

In the example shown in FIG. 5B, similarly to the example shown in FIG. 5A, the discontinuous portion (seal portion) of the seal portion 20 is located near the boundary between _{the thick zone Z 3} and the thin zones Z _2a and Z _2b. The non-existent portion of 20) is formed, but the design of the seal portion 20 is different from that of FIG. 5 (a). In this way, in the example shown in FIG. 5 that forms the position where the width becomes zero, the seal portion 20 having various designs can be formed. Also in the example shown in FIG. 5B, since the peeling resistance becomes large when trying to restart after the progress of the peeling is interrupted, the peeling progress suppressing action of the peeling suppressing unit 30 can be improved.

In the example shown in FIG. 5 (c), the seal portion 20 becomes discontinuous at the boundary between _{the thick zone Z 3} and the thin zones Z _2a and Z _2b , similarly to the examples shown in FIGS. 5 (a) and 5 (b). As a result, the effect of suppressing the progress of peeling is exerted, but the design of the shape of the seal portion 20 in the _{thin zones Z 2a} and Z _{2b is enhanced.} In the example of FIG. 5C _{, the seal portion 20 in the thin zones Z 2a} and Z _2b has a shape in which a plurality of heart shapes are connected. These heart shapes may be continuous or discontinuous. By enhancing the design of the seal portion 20 in this way, it becomes easier to distinguish it from other portions of the seal portion 20. Therefore, for example, by adding an explanatory note to the packaging sheet, the package accommodating the packaging absorbent article, or the like, it is possible to inform the user that the packaging sheet is difficult to peel off at the peeling prevention unit 30.

In the examples of FIGS. 5A to 5C, the seal portion 20 is discontinuous in the longitudinal direction D1, but the seal portion 20 includes a line in which the contour of the absent portion is inclined with respect to the width direction D2. .. That is, when a virtual line is drawn in parallel with the width direction D2, the virtual line is configured to overlap the seal portion 20 at any position in the longitudinal direction D1. As a result, dust and dirt can be prevented from entering from the edge of the package absorbent article 100, and the contained absorbent article can be kept hygienic.

In any of the examples shown in FIG. 5, the configuration and function of the second peeling suppressing unit 32 are the same as those of the first peeling suppressing unit 31.

(Second Embodiment)
FIG. 6 shows the packaging absorbent article 200 according to the second embodiment. The overall configuration of the package absorbent article 200 is the same as that of the first embodiment (FIGS. 1 to 5), but the width of the seal portion 20 is not locally changed, and the peeling restraining portion 30'(first peeling) is performed. The restraint section 31'and the second peeling restraint section 32') are formed.

In the example of FIG. 6, the seal portion 20 extending in the longitudinal direction D1 has a weak seal portion 20w located outside the width direction D2 and a strong seal portion 20s located inside the width direction D2. In the weak seal portion 20w, the bonding strength per unit area is relatively weak, and in the strong sealing portion 20s, the bonding strength per unit area is relatively strong. The difference in the strength of the joint strength is that when the seal portion is formed by using a roll pair, the height of the convex portion corresponding to the joint portion formed on the surface of the roll is changed, or the height of the convex portion corresponding to the joint portion is changed. It can be obtained by changing the area of the convex portion per unit area, or both. In the illustrated example, there is a portion having a strong bonding strength inside the width direction D2, but the portion in the thin zones Z _2a and Z _2b is a portion showing a high bonding strength and acts as a peeling suppressing portion. Can be played.

(Third Embodiment)
FIG. 7 shows the packaging absorbent article 300 according to the third embodiment. The overall configuration of the package absorbent article 300 is the same as that of the first embodiment (FIGS. 1 to 4), but in this embodiment, the seal portion 20 is the peeling restraining portion 30 (the first peeling suppressing portion 31 and the first peeling suppressing portion 31). 2 The peeling restraining unit 40 (the first peeling suppressing unit 41 and the second peeling suppressing unit 42) is provided in place of the peeling suppressing unit 32).

The peeling restraining unit 40 (the first peeling suppressing unit 41 and the second peeling suppressing unit 42) in the present embodiment includes a portion formed so as not to be peeled off. In this embodiment, the means for forming the peeling suppressing portion 40 is not particularly limited. For example, the peeling suppressing portion 40 has a thin zone (for example, high temperature and / or high pressure) under conditions higher than the condition for forming the peelable joint portion of the sealing portion 20 after the sealing portion 20 is formed. The packaging sheets may be formed by crimping or fusing the packaging sheets in a thin zone Z _2a and a second thin zone Z _{2b) so as not to be peeled off.} Further, an adhesive may be applied so that the peeling suppressing portion 40 is formed in the thin zone when the packaging sheet 10 is folded when the packaging absorbent article 300 is manufactured. Alternatively, the peeling suppressing portion 40 may be formed by sewing after the sealing portion 20 is formed.

As in the example of FIG. 7, since the peeling suppressing portion 40 is formed so as not to be peeled off, the peeling progress suppressing action of the peeling suppressing portion 40 can be surely exerted. Therefore, even when a large force is applied by the user at the time of opening, the portion of the sealing portion 20 where the packaging sheet is peeled off can be reduced, and the peeling sound can be effectively reduced.

In the example of FIG. 7, the peeling suppressing portion 40 is formed over the width direction D2 of the seal portion 20, but may be formed over a part of the width direction D2 of the seal portion 20. Further, the peeling suppressing portion 40 may have a curved shape instead of the linear shape as shown in the figure. Further, the shape may be formed by repeating a predetermined pattern, for example, in a zigzag shape or a wavy shape.

FIG. 8 shows a modified example of the peeling prevention unit 40 in the third embodiment. As shown in FIG. 8, the peeling suppressing portion 40 may have a shape of a predetermined plane figure extending in the longitudinal direction D1 and the width direction D2 instead of the linear shape extending in the width direction D2.

For example, in the example of FIG. 8A, the peeling suppressing unit 40 (the first peeling suppressing unit 41 and the second peeling suppressing unit 42) has a diamond shape. As described above, the peeling suppressing unit 40 (the first peeling suppressing unit 41 and the second peeling suppressing unit 42) has a polygonal shape such as a triangle or a quadrangle, a circle, an ellipse, a star shape, a heart shape, or the like. You can. Here, if the peelable deterrent portion 40 that cannot be peeled off is formed so as to be visible, the design of the package absorbent article 300 can be improved.

Further, as shown in FIG. 8B, the peeling suppressing unit 40 (the first peeling suppressing unit 41 and the second peeling suppressing unit 42) has a thin zone (first thin zone Z _2a and second thin zone Z _2b ). It may be formed on the whole of. As a result, the bonding between the packaging sheets in the thin zone (first thin zone Z _2a and second thin zone Z _2b ) is strengthened, and the thin zone (first thin zone Z _2a and second thin zone Z _2b ) is further formed. It can be made more difficult to open. Even when the user opens the package with a strong force, the action of suppressing the progress of peeling can be further ensured.

The peeling suppressing portion 40 formed in the thin zone (first thin zone Z _2a or second thin zone Z _2b ) is preferably 2 to 40 mm from the boundary between the thin zone and the thick zone Z _3. More preferably, it can be formed at a distance of 3 to 20 mm. As a result, when the first step of peeling the first region R1 at the time of opening is completed, the entire second region R2 can be exposed, and in the second step of peeling the second region R2, the second region R2 is difficult to grasp or It is possible to prevent it from becoming difficult to lift. In addition, it is possible to reduce the possibility that the thick zone cannot be peeled off due to a manufacturing error and cannot be opened.

(Fourth Embodiment)
FIG. 9 shows the packaging absorbent article 400 according to the fourth embodiment. The overall configuration of the package absorbent article 400 is the same as that of the first embodiment (FIGS. 1 to 5), but in this embodiment, the seal portion 20 is the peeling restraining portion 30 (the first peeling suppressing portion 31 and the peeling suppressing portion 31). Instead of the second peeling restraining unit 32) or the peeling suppressing unit 40 (the first peeling suppressing unit 41 and the second peeling suppressing unit 42), the peeling suppressing unit 50 (the first peeling suppressing unit 51 and the second peeling suppressing unit 52) have.

As shown in FIG. 9, the peeling suppressing portion 50 (the first peeling suppressing portion 51 and the second peeling suppressing portion 52) in the present embodiment is a notch formed in the seal portion 20. In this way, the peeling restraining unit 50 (the first peeling suppressing unit 51 and the second peeling suppressing unit 52) is formed as a notch formed in the thin zone (including a partial notch such as a perforation). The material itself at the edge of the package-absorbent article 400 becomes discontinuous, and the continuity of the progress of peeling at the seal portion 20 is reduced or eliminated. Thus, for example, the first release preventing part 51, in the first step of peeling off the first region R1 upon opening, the progress of peeling the first thin zone Z _2a is stopped, first release of the first thin zone Z _2a The packaging sheet is difficult to peel off or does not peel off at the portion outside D1 in the longitudinal direction from the restraining portion 51. Therefore, the portion of the seal portion 20 where the packaging sheet is peeled off at the time of opening is reduced, and the peeling noise can be effectively reduced.

FIG. 10 shows a modified example of the peeling suppressing unit 50 (the first peeling suppressing unit 51 and the second peeling suppressing unit 52) in the fourth embodiment. In the example of FIG. 10, the peeling suppressing portion 50 is formed not as a notch but as a notch, that is, a portion having a predetermined area removed from the edge portion of the package absorbent article 400. In this example as well, as in the example of FIG. 9, the peeling suppressing unit 50 (the first peeling suppressing unit 51 and the second peeling suppressing unit 52) can suppress the progress of peeling at the time of opening.

The peeling prevention portion 50, which is a notch or notch in the present embodiment, can be formed at the same time when the individual package (packaging absorbent article) is separated by a cutter or the like after the seal portion 20 is formed. The first peeling preventing part 51 formed on the first thin zone _{Z 2a} from the boundary between the first thin zone _{Z 2a} and thickness zone _{Z 3,} preferably 1 to 8 mm, more preferably 2~5mm Can be formed apart. As a result, when the first step of peeling the first region R1 at the time of opening is completed, the entire second region R2 can be exposed, and in the second step of peeling the second region R2, the second region R2 is difficult to grasp or It is possible to prevent it from becoming difficult to lift.
