Description

  The present invention particularly relates to an absorbent article with wings that facilitates the peeling of release paper temporarily attached to a wing portion.

  While sanitary napkins and cage sheets are attached to shorts so that they are applied to local parts of the human body during discharge of menstrual blood and cages, they are used for walking and light exercise that are normally performed in daily life. If it is performed inside, the relative position with the local part becomes easy to shift with these actions. When such a shift occurs, menstrual blood and urine easily leak from the shorts. Therefore, it is very important to prevent such a shift.

  For example, FIG. 6 shows a rear view of a sanitary napkin that has been conventionally used, and FIG. 7 shows a sectional view thereof. The napkin body 1 is held by a holding body 2, and the surface of the holding body 2 that is on the shorts side when used (hereinafter referred to as a non-use surface, and the surface that is on the human body side is referred to as a use surface). The adhesive 4 for preventing misalignment is applied so as to cover most of the adhesive, and before use, the adhesive 4 for preventing misalignment is temporarily covered with release paper 5 made of, for example, a plastic film. It is worn. In the present specification, “temporary attachment” means that the adhesive means is attached in a state where the adhesive force is not reduced.

  Prior to using this sanitary napkin, the release paper 5 is peeled off from the sanitary napkin, and the sanitary napkin is stuck and fixed to the inner surface of the shorts via the adhesive 4 for preventing misalignment. In general, since the relative position between the human body and the shorts is substantially stable, the above-described misalignment can be prevented by fixing the relative position between the shorts and the napkin.

  However, with this sanitary napkin, although there is no hindrance in daily life, the displacement of the relative position between the sanitary napkin and the shorts, the so-called lateral misalignment, cannot be avoided during intense exercise, etc. As menstrual blood leaked from shorts.

In order to prevent such lateral displacement, a sanitary napkin with a wing as shown in FIG. 8 has been used in recent years. This napkin is integrally provided with a napkin main body 1 on a holding body 2 composed of a base portion 21 and wings 22 and 22 extending from both ends in the width direction. The anti-slip adhesive 4A is applied in an appropriate pattern, and the non-slip adhesive 4B is applied to the non-use surface side of each wing 22, 22, and the release paper is applied on these anti-slip adhesives 4A, 4B. 5A and 5B are temporarily attached. When the sanitary napkin is fixed to the shorts, as shown in FIG. 9, the release paper 5 </ b> A is peeled off and the napkin is fixed to the crotch portion of the shorts S, and then the wing 22 is attached to the crotch portion of the shorts S. The side edges are wrapped around, the release paper 5B of the wings 22 and 22 is peeled off, and the wings 22 and 22 are fixed. The sanitary napkin is firmly fixed to the shorts S by the shift preventing adhesive 4A applied to the base portion 21 and the shift preventing double-sided adhesive 4B attached to the wings 22 and 22, Subsequent lateral displacement is prevented.
Japanese Patent Laid-Open No. 5-220192

  By the way, in the sanitary napkin with wings, the release papers 5A and 5B are attached to the slippage preventing adhesives 5A and 5B, which are temporarily attached to the slippage preventing adhesives 4A and 4B. An area that is larger than the area of the agents 4A and 4B is formed to form a non-temporarily attached portion, and the unattached portion can be peeled off as a knob.

  In this case, the release paper 5A temporarily attached to the slip prevention adhesive 4A of the base portion 21 has a large area, so that the release is relatively easy. However, the slip prevention adhesive 4B of both the wings 22 and 22 is used. In the case of the release paper 5B temporarily attached to the paper, since the area of the release paper is small, for example, the wing 22 is bent so that the knob portion of the release paper 5B protrudes outward when peeling. Therefore, the picked portion had to be picked and peeled off, which was very troublesome.

  Accordingly, an object of the present invention is to provide a wing such as a sanitary napkin with a wing that can easily peel off a release paper, in particular, a release paper temporarily attached to an adhesive means for preventing misalignment of both wings, and a similar wing sheet. The object is to provide an absorbent article.

In order to solve the above-mentioned problems, the present invention integrally has wings that wrap around the side edges of the crotch portion of the shorts and are respectively applied to the outer surface of the shorts on both sides in the middle in the longitudinal direction. In the absorbent article with wings, the adhesive means for preventing slippage is formed on each non-use surface, and the release paper is temporarily attached to the adhesive means for preventing slippage in a state where it is completely covered.
Each of the release papers has at least an unattached portion extending inward beyond the inner edge of the corresponding adhesive means for preventing misalignment, and all or a part of the unattached portion is opposite. It is folded to the side and becomes a knob that stands up in the wing unfolded state ,
Both wings are characterized in that a line passing through the folding position of the unattached portion is folded as a fold line .

In the absorbent article with wings according to the present invention, since the knob part stands when both folded wings are developed, the user can easily peel the release paper by picking this part.

  As is apparent from the above description, according to the present invention, it is possible to provide an absorbent article that can easily peel release paper, particularly release paper temporarily attached to both wings.

Hereinafter, the present invention will be specifically described with reference to a sanitary napkin with wings shown in the drawings.
FIG. 1 is a rear view of a sanitary napkin with wings according to the present invention, and FIG. 2 is a view taken along the line II-II. The napkin N is composed of a strip-shaped napkin body 1 that is appropriately assembled with a known structure, and a holding body referred to in the present invention, for example, a polyethylene laminated nonwoven fabric (hereinafter simply referred to as a polylaminated nonwoven fabric) 2. The polylaminated nonwoven fabric 2 is a nonwoven fabric on the use surface side, a non-use surface side is made of polyethylene, and a base portion 21 to which the napkin body 1 is fixed and wings 22 and 22 extending outward from both sides of the base portion 21. It consists of and. The napkin body 1 is disposed along the longitudinal direction of the base portion 21 of the polylaminated nonwoven fabric 2, and the entire or part of the contact surface is firmly adhered to the polylaminated nonwoven fabric 2 by the hot melt adhesive H. The portions 3 and 3 where the absorbers at both ends in the longitudinal direction do not exist are integrated with the polylaminated nonwoven fabric 2 by heat sealing.

  Adhesive means 4A, 4A for preventing slippage are formed on the non-use surface side of the base portion 21 of the polylaminated nonwoven fabric 2 by an appropriate coating pattern, and cover all of the adhesive means 4A, 4A for preventing slippage. A large release paper 5A is temporarily attached. On the other hand, the non-use surface of the wing 22 is also provided with a slip-preventing adhesive means 4B, and extends further inward beyond the inner edges 4a, 4a of the slip-preventing adhesive means 4B, 4B. There is an untemporarily attached portion 5a, 5a, and a part of the unattached portion 5a, 5a is folded back to the opposite side to form a knob (5a) that stands up in a wing unfolded state. In addition, as the adhesive means 4A, 4B for preventing misalignment, a double-sided tape or the like can be used in addition to the adhesive hot melt adhesive. Further, the folding of the knob portion 5a may be performed by folding the entire unattached portion 5a.

Next, the suitable manufacturing method of the sanitary napkin with a wing which concerns on this invention is demonstrated.
In FIG. 3, the sanitary napkin with wings is supplied with the napkin bodies 1, 1,... Intermittently on the use surface side (nonwoven fabric side) of the material of the band-shaped polylaminated nonwoven fabric 2, and is bonded by a hot melt adhesive. Both ends in the longitudinal direction are heat-sealed and integrated, and the non-use surface is coated with adhesives 4A and 4A for preventing misalignment, and the release paper 5A is placed so as to cover the adhesives 4A and 4A for preventing misalignment. Temporarily worn. In addition, the adhesives 4B and 4B for preventing misalignment are applied to the positions corresponding to the wings on both sides of the release paper 5A, and the release papers 5B and 5B are temporarily attached so as to cover the adhesives 4B and 4B for preventing misalignment. In this case, the release papers 5B and 5B have unattached portions 5a and 5a that extend further inward beyond the inner edges of the adhesives 4B and 4B for preventing misalignment.

  Then, after the raw material of the polylaminated nonwoven fabric 2 is cut into a predetermined shape and a single sanitary napkin is manufactured, in the step of folding both wings 22 and 22 to the napkin body 1 side for packaging, the release papers 5B and 5B The sailor 30 folds the line L passing through the unattached portions 5a and 5a as a fold line. If this folding state is illustrated in detail, it will become FIG. 4 (A)-(B). In FIG. 4 (A), the wing 22 is folded by folding back 180 °, with the line L passing through the unattached portion 5a of the release paper 5B as a fold line. As a result, a tight fold is imparted to the proximal end of the knob 5a, and as shown in FIG. 5, when the wing 22 is unfolded in use, the knob 5a stands up. The user can easily peel the release paper 5B by picking the raised knob 5a.

  In addition, as another method of raising the knob 5a, it is possible to make a crease in advance before temporarily attaching the release paper 5B. In this case, however, a separate crease is provided in the state of the release paper 5B alone. Since a process is required, the above-described manufacturing method is more practical.

  In the above embodiment, a sanitary napkin having a structure in which a napkin body is bonded onto a polylaminated nonwoven fabric has been described as an example. However, other structures such as a liquid-impervious sheet and a liquid-permeable sheet are absorbed. The present invention can be applied to all absorbent articles having wings on both sides, such as a sanitary napkin having a structure in which a body is interposed.

It is a rear view of the sanitary napkin which concerns on this invention. It is the II-II arrow directional view. It is a figure which shows the manufacturing process of the sanitary napkin with a wing which concerns on this invention. It is an enlarged view which shows a wing folding process. It is a principal part expanded state figure of the sanitary napkin with a wing which concerns on this invention. It is a rear view of the conventional sanitary napkin. FIG. It is a rear view of the conventional sanitary napkin with a wing. It is the fixed state perspective view with respect to the shorts of the sanitary napkin with a wing.
