Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a so-called wing type sanitary napkin for absorbing and retaining menstrual blood, and more particularly to a so-called wing type sanitary napkin.

[0002]

[Prior art]

 Conventionally, a so-called wing type sanitary napkin having wings on both sides of a main body is known. In this napkin, adhesive portions for wearing shorts are provided on the non-skin-contacting back surfaces of the main body portion and both wing portions, and each is covered with three release protective pieces that are separated from each other. Usually, this napkin has both wings folded toward the non-skin contact back side and then enclosed in individual bags.

[0003]

[Problems to be solved by the device]

 In the napkin enclosed in the individual bag, a part of the mold release protection piece of the main body is joined to the inner surface of the individual bag, and the protective piece is left on the individual bag side when taking out the napkin, and it is automatically peeled off. The technique to do so is known from, for example, Japanese Utility Model Publication No. 60-79421 and Japanese Utility Model Publication No. 2-25226. When these known techniques are applied to a non-wing type napkin, the napkin taken out from the individual bag is convenient because it can be directly crimped to the shorts because the adhesive portion of the main body is already exposed. However, the above-mentioned known technique is applied to the conventional wing type napkin as follows. When the napkin is taken out of the individual bag, at the same time when the release protection piece of the main body part is peeled off, the folded wing part is bounced off by the protection piece in the direction of opening the fold, but in the meantime, the wearer is However, since the wing part is involved in the motion of the wing part such as supporting the wing part that has been bounced off as it is, the wing part has a folding tendency toward the non-skin-contacting back surface side. Bend to the side of and stick to the adhesive part where the wing part and / or the mold release protection piece of the part is exposed. Therefore, in order to restore the wing portion to the normal state, it cannot be easily peeled off even if it is peeled from the main body portion, and even if it is possible, the wing portion and / or the main body portion will eventually be damaged, It is often the case that the napkin itself cannot be used or the wings cannot be used. When the release protection piece adheres, it is troublesome to peel off the protection piece, even if it is not so much.

Therefore, in the present invention, by connecting the wing portions on the front surface side of the main body portion with a release protection piece so as not to bend to the non-skin contact back surface side, It is an object to solve the problem of the napkin enclosed in the bag.

[0005]

[Means for Solving the Problems]

 The point where this device serves as a means for solving the above problems is as follows.

This invention is based on the premise that the absorbent body is interposed between the skin-contacting front surface and the non-skin-contacting back surface, and that the absorbent body extends laterally outward from the opposite edge of the central area of the absorbent body. A sanitary napkin with individual bags, each of which is composed of a wing part that is attached to the main body part and both wing parts. is there.

Under such a premise, a feature of the present invention is that a part of the mold release protective piece for covering the adhesive part of the body part is joined to the inner surface of the individual bag, while both wing parts are provided on the opposite edges. Along with this, there is a mold release protective piece for the wing part that folds along the surface of the main body part and covers these folded wing parts.

[0008]

[Action]

 In the so-called wing type napkin according to the present invention, the mold release protective piece for the main body is joined to the inner surface of the individual bag, and in the taken out napkin, the protective piece remains in the individual bag and the adhesive portion of the body part is exposed. ing. On the other hand, both wing parts folded to the surface side of the body part are connected by the release protection piece for wing part, do not move unintentionally and do not adhere to the adhesive part of the body part.

【Example】

 The details of the sanitary napkin in the individual bag according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 and FIG. 2 are a partially cutaway perspective view of an individual bag-containing sanitary napkin 1 and a sectional view taken along the line AA.

FIG. 3 is a perspective view showing the napkin 30 taken out from the individual bag 2.

FIG. 4 is a plan view of the napkin 30 enclosed in the individual bag 2, where (A) shows the skin contact surface side and (B) shows the non-skin contact back surface side.

As shown in FIG. 4, the napkin 30 includes a liquid-permeable top sheet 32 forming a skin-contacting surface, a liquid-impermeable backing sheet 33 forming a non-skin-contacting back surface, and both sheets 3 The main body portion 35 is composed of an absorber 34 interposed between the second and the third body 33, and left and right blade portions 40 extending laterally outward from the facing edges 36 in the central region of the main body portion 35. The wing portion 40 is folded along the facing edge 36 toward the surface sheet 32. The backsheet 33 of the main body portion 35 has two adhesive application areas 37 extending in the longitudinal direction of the napkin 30, and the backsheet 33 of each wing portion 40 has an adhesive application area 42. The adhesive application area 37 is covered with one sheet of mold release protection piece 38, and the left and right adhesive application areas 42 are one blade part release protection piece 43 that connects each blade part 40. It is covered with. The connection by the protection piece 43 is maintained by the protection piece 43 being adhered to the adhesive application area 42.

Returning to FIG. 1 and FIG. 2, the individual bag 2 has opposed edges 2A and 2B in the longitudinal direction of the napkin 30, while having opposed sides 2C and 2D in the width direction, and has a rectangular planar shape. It is a sealed bag. Near the edge 2A, there is a perforation 3 which is parallel to the edge 2A, and the perforation 3 can be opened here to take out the napkin 30. The napkin 30 to which both wing portions 40 are connected is folded by folding the surface sheet 32 inward in the longitudinal direction into three folds, and at that time, the end portion 39 on the outer side of the napkin 30 is formed with the perforation 3 and the edge portion 2A in the individual bag 2. It is enclosed in an individual bag 3 so as to be located between the two. The mold release protective piece 38 for the main body is folded back to the outside in the vicinity of the end 39, and is joined to the inner surface of the individual bag 2 with the adhesive 4 at a position where the folded back end 38A is closer to the edge 2B than the perforation 3. is there. This bonding strength is such that the napkin 30 is not easily peeled off when taken out from the individual bag 2.

FIG. 3 shows that in the sanitary napkin 1 having such a structure, the individual bag 2 is opened according to the perforations 3, and the individual bag 2 is held by one hand (not shown) and the other hand (not shown). FIG. 9 is a schematic view showing a state in which the main body release protection piece 38 is peeled off from the pressure-sensitive adhesive coating area 37 and left on the individual bag 2 side when the end portion 39 of the napkin is grasped and taken out by the method of FIG. When the individual bag 2 is opened, the end 39 of the napkin faces the opening, and this end can be easily grasped. Since the adhesive application area 37 of the napkin 30 that has been taken out is already exposed, the napkin 30 is pressure-bonded as it is to the inside of the crotch part of the wearing shorts, then the wing release protective piece 43 is peeled off, and each wing portion 40 is moved to the outside. Fold back and crimp to the outside of the crotch part of the wearing shorts. Since the inner surfaces of the individual bag 2 which face each other at the edge portion 2A are heat-sealed (see FIG. 2), the end portion 38A of the protective piece 38 is sandwiched between these inner surfaces and heat-sealed as it is, and the end portion 38A is individually sealed. It can be joined to the bag 2, and in the present invention, such joining is also called joining to the inner surface of the individual bag 2.

In the napkin 30, the front and back sheets 32, 33 are closely joined at the portions extending around the absorber 34. The wing portion 40 is formed by joining front and back sheets 32 and 33 extending from the main body portion 35 to each other. Nonwoven fabric or perforated plastic film for the top sheet 32, plastic film for the back sheet 33, crushed pulp or a mixture of crushed pulp and super absorbent polymer for the absorber 34, plastic film for the release protection pieces 38, 43. A sheet such as paper or paper can be surface-treated and used as necessary. Plastic film such as polyethylene film or paper can be used for the individual bag 2. For joining these materials forming the sanitary napkin 1, an adhesive such as a hot melt adhesive, an adhesive, or a heat sealing technique can be used.

[0017]

[Effect of device]

 In this device, both wings of a so-called wing type napkin are folded and connected to the front side of the main body, so that when the napkin is taken out from the individual bag, the mold release protective piece peels off. Even if it remains on the bag side, the wings will not adhere to the exposed adhesive on the main body. Therefore, the wearer can crimp the taken out napkin to the inner side of the crotch part of the wearing shorts without worrying about the existence of the wing portion.
