Description

Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention has excellent handleability and can be crimp-fixed to shorts or the like without touching the use surface. Furthermore, a sanitary napkin with a wing or a sheet of a voucher for convenient packaging. Such as absorbent articles.

[0002]

2. Description of the Related Art For example, a sanitary napkin is attached to shorts so that it may be applied to a local part of the human body during menstrual blood discharge. If it is performed during use, the relative position with the local portion is likely to be displaced due to those actions. If such a deviation occurs,
It is very important to prevent such lateral displacement because menstrual blood easily leaks from the shorts.

Recently, in order to prevent lateral displacement, a sanitary napkin as shown in FIG. 13 has been used. The sanitary napkin 20 is coated with an adhesive on the non-use surface side so as to cover most of it (not shown). The adhesive force of this adhesive prevents the gap from the shorts and prevents the napkin from displacing. Wings W, W extending outward are integrally provided on both sides in the longitudinal direction of the main body, and adhesives 21, 21 are applied to each of the wings W, W.
In the product state, release paper is temporarily attached to each of the adhesive surfaces 21, 21 ... In a peelable state.

When fixing the sanitary napkin to the shorts, first peel off the release paper temporarily attached to the non-use surface side, apply it to the crotch portion of the shorts, and then temporarily attach it to both wings W, W. Remove the release paper,
As shown in FIG. 4, the wings W, W are turned on the side edges of the crotch portion of the shorts 22 and applied to the outer surface of the crotch portion of the shorts 22. The lateral displacement of the napkin is prevented by the adhesive on the non-use surface side and the adhesive on the wings W, W.

On the other hand, absorbent articles such as sanitary napkins are
For hygiene reasons and convenience of carrying, they are usually sold individually in individual packages and packaged individually.

[0006]

However, in the case of the absorbent articles such as the sanitary napkin with wings and the voucher sheet with wings as described above, the lateral displacement prevention effect is very high, but the handling property is poor. It is a thing.
For example, in the peeling work of each release paper, if the release paper is temporarily attached to the non-use surface side of the absorbent article main body, it is easy to peel because of its large area, but it is temporarily attached to both wings. In the case of the release paper, the area of the release paper is small and it is difficult to remove the release paper.

Further, when applying the absorbent article to the shorts, the napkin is fixed by pressure from the surface side with fingers or palms in order to enhance the adhesive effect, but when the use surface is directly pressed by the hand, Since the plaque on the hand and the bikini are transferred to the surface sheet surface, there is a problem that it is very unsanitary.

On the other hand, the absorbent article is individually packaged in individual bags for hygiene reasons as described above, but the cost for this individual package is required separately and In use, it is necessary to open the individual bag and take out the absorbent article inside.

Therefore, a first object of the present invention is to provide a release paper,
In particular, the release paper temporarily attached to both wings should be able to be easily peeled off, and it should be possible to press and fix it to the shorts without touching the topsheet directly by hand. The second problem is to make the packaging more convenient, economical and easy to handle.

[0010]

SUMMARY OF THE INVENTION In order to solve the above-mentioned first problem, the present invention applies to both sides of the middle in the longitudinal direction, the side edge of the crotch part of the shorts in use and the outer side of the shorts. In an absorbent article, which has a wing that breaks off, and in which the slip-preventing adhesive means are formed on the surfaces of the both wings that are applied to the shorts, the both wings are folded toward the use surface side, and the slip-preventing adhesive is used. A cover sheet that is temporarily attached to the means and substantially covers the use surface of the absorbent article is provided.

As another aspect of this case, in the absorbent article, both the wings are folded toward the use surface side, and the release paper is temporarily attached across both the deviation preventing adhesive means, and A cover sheet is provided which is adhered to a release paper and substantially covers the use surface of the absorbent article.

A second object of the present invention is to have wings on both sides in the middle in the longitudinal direction, which wrap around the side edges of the crotch portion of the shorts and are applied to the outer surface of the shorts in use, respectively. In an absorbent article in which a slip-preventing adhesive means is formed on the surface applied to the shorts, both wings are folded toward the use surface side, and the absorbent article is substantially attached to the slip-preventing adhesive means to substantially form the absorbent article. A cover sheet for covering the cover sheet, and folding the cover sheet in the longitudinal direction with the cover sheet as the outer surface side, and heat-sealing both side edge portions of the cover sheet in the folded state to package the absorbent article. It is a thing.

As another aspect of this case, in the absorbent article, both wings are folded to the use surface side, and a release paper is temporarily attached while straddling both displacement preventing adhesive means. Provided with a cover sheet that substantially adheres to the absorbent article by being adhered to a release paper, and with the cover sheet as the outer surface side, is folded in the longitudinal direction, and heat-sealed both side edge portions of the cover sheet in the folded state, The absorbent article is packaged.

When the above-mentioned cover sheet is used as a packaging sheet, it is desirable to provide a fastening tape on one longitudinal end of the cover sheet.

[0015]

In the case of the first aspect of the present invention, both wings are folded toward the use surface side, and a cover sheet is provided which is temporarily attached to the displacement preventing adhesive means and substantially covers the use surface of the absorbent article.

Therefore, the absorbent article can be crimped and fixed to the shorts by pressing the cover sheet with a finger or a palm without directly touching the use surface, which is very hygienic.

Further, since the cover sheet temporarily attached by the displacement preventing adhesive means is used instead of the conventional release paper, the cover sheet can be easily picked and peeled off when using the wing portion. This makes it possible to reduce the time and effort required for the peeling work as in the conventional case, and the handleability is remarkably improved.

Next, in the case of the second aspect of the present invention, both wings are folded toward the use surface side, and a cover sheet that is temporarily attached to the displacement preventing adhesive means and substantially covers the absorbent article is provided, and the cover sheet is provided. The absorbent article is packaged as a packaging sheet. Therefore, it is not necessary to separately prepare a packaging bag, which is advantageous in terms of cost, and when the cover sheet is torn and deployed, the absorbent article is also deployed at the same time and is ready for use. The work of is simplified and is easy to handle.

II-II sectional drawing, FIG. 3 is the rear view. The sanitary napkin N (hereinafter, also simply referred to as a napkin) shown in FIG. 1 includes a liquid-impermeable sheet 1 made of a polyethylene sheet or the like, a liquid-permeable sheet 3 made of a nonwoven fabric or a perforated plastic sheet, and a space therebetween. The absorbent body 2 is made of cotton-like pulp, synthetic pulp, or the like. Further, the liquid-impermeable sheet 1 and the liquid-permeable sheet 3 have their outer edge portions F overlapped with each other by an adhesive such as hot melt or an adhesive means such as heat seal, and an intermediate portion in the longitudinal direction of the napkin N. On both sides of the section,
Without the absorbent body 2, the liquid-impermeable sheet 1 and the liquid-permeable sheet 3 extend together to form flap-shaped wings W, W.

On the liquid-impervious sheet surface side of the wings W, W, hot-melt pressure sensitive adhesives 4, 4 for slippage prevention are applied by means of rolls or nozzles. In the present invention, this wing W, W W is folded to the use side,
A cover sheet 5 which substantially covers the use surface of the napkin is provided by using the hot-melt pressure-sensitive adhesives 4 and 4 for preventing displacement as a temporary attachment means. The cover sheet 5 may be made of any suitable material as long as it is peelable, and release paper, plastic sheet, plastic film or the like is preferably used. In this case, it is not necessary to cover the entire use surface with the cover sheet 5, but it is desirable that the cover sheet 5 has a size that covers at least 70% or more, preferably 80% or more of the absorber region.

On the other hand, as shown in FIG. 3, the non-use surface (the surface of the liquid impermeable sheet) of the napkin is provided with, for example, a hot-melt pressure-sensitive adhesive 8 for preventing misalignment over a relatively large area. The adhesive hot melt agent 8 is applied in a pattern and is covered with a release paper 7.

In using the above-mentioned sanitary napkin N, the release paper 7 on the back side is first peeled off and applied to the crotch portion of the shorts, and the cover sheet 5 is pressed from above the cover sheet 5 with a finger or a palm to make a napkin. Press on the shorts,
Firmly crimp and fix. After that, the cover sheet 5 is picked and peeled off, the wings W, W are turned around the side edge of the crotch part of the shorts, applied to the outer surface of the shorts, and pressed from above the wings W, W with fingers or palms, Firmly crimp and fix. The sanitary napkin thus mounted was completely prevented from lateral displacement by the adhesive hot melt agent 8 on the non-use surface side and the hot melt adhesive agents 4, 4 for preventing the wing W, W from shifting. It is installed in the state.

Next, a sanitary napkin of another embodiment shown in FIG. 4 is an example in which the napkin main body is the same as that of the first example, but the attachment mode of the cover sheet 5 is changed. First, the two wings W, W are folded to the use surface side, the release paper 6 is temporarily adhered across both the displacement preventing adhesive means 4, 4, and the hot applied to the front surface side of the release paper 6 is applied. A cover sheet 5 is provided which substantially covers the use surface of the sanitary napkin using the melt adhesive 9 as a fastening means. In this case, the release paper 6 and the cover sheet 5 are firmly bonded so as not to be easily peeled off, and when the cover sheet 5 is pinched and peeled off, the release paper 6 is peeled off at the same time.

On the other hand, in the second aspect of the present invention, as shown in FIG. 6, hot-melt pressure-sensitive adhesives 4 and 4 for preventing displacement are rolled on the liquid-impermeable sheet surface side of the wings W and W. Alternatively, it is applied by a nozzle or the like, and in particular, the wings W, W are folded toward the use surface side, and the hot-melt pressure-sensitive adhesives 4 and 4 for preventing displacement are used as temporary attachment means to substantially cover the napkin. A cover sheet 5A is provided. The cover sheet 5A may be made of any suitable material as long as it is releasable, and release paper, plastic sheet, plastic film or the like is preferably used. A fastening tape 10 is fixed to the cover sheet 5A at one end in the longitudinal direction. As the cover sheet 5A, it is preferable to use a cover sheet having a width larger than that for covering the entire surface of the sanitary napkin N, but in some cases, on the side opposite to the side where the fastening tape 10 is fixed, , As shown by the chain line L, there is no problem even if a part of the sanitary napkin N is exposed. However, even in this case, in order to fix the napkin N to the shorts by crimping, the use surface portion on which the absorbent body 2 is arranged needs to be substantially covered with the cover sheet 5A. Further, as shown in the rear view of FIG. 8, the non-use surface (the liquid impermeable sheet surface side) of the napkin N is appropriately covered with, for example, a hot-melt adhesive 8 for preventing slippage over a relatively large area. The adhesive hot melt agent 8 is coated with a release paper 7.

Such a sanitary napkin N is shown, for example, in FIG.
It is packaged according to the procedure shown in (a) to (d). First,

After folding back one end side portion, as shown in Fig. 9 (c), fold the other end side portion on which the fastening tape 10 is fixed in a staggered state so as to overlap it,
Finally, the fastening tape 10 is fastened and fixed on the cover sheet 5A. From this state, as shown in FIG. 10, both side edges 11 and 12 of the cover sheet 5A are heat-sealed along the outer edges thereof to form the cover sheet 5A.
A sanitary napkin packaged as a packaging sheet is obtained. In addition, instead of fastening with the fastening tape 10,
The edge of the cover sheet 5 can also be hot-melt bonded or heat-sealed bonded. In the case of this example,
Although the napkin is wrapped in three in the longitudinal direction, it is also possible to fold it in two, four or more folds.

In using the above-mentioned sanitary napkin N, first, the fastening tape 10 is peeled off, and both edges 11, 1
The folded portion is unfolded while tearing the joining portion of No. 2 into the plane unfolded state shown in FIG. 9 (a). After that,
The sanitary napkin N is fixed to the shorts by the procedure described in the first invention.

Next, another sanitary napkin shown in FIG. 11 is an example in which the mounting manner of the cover sheet 5A is changed, although the napkin body is the same as the other ones. First, the two wings W, W are folded to the use surface side, the release paper 6 is temporarily adhered across both the displacement preventing adhesive means 4, 4, and the hot applied to the front surface side of the release paper 6 is applied. A cover sheet 5 is provided which substantially covers the sanitary napkin N using the melt adhesive 9 as a fastening means. Also in this case, the release paper 6 and the cover sheet 5A are firmly adhered so as not to be easily peeled off. When the cover sheet 5A is pinched and peeled off, the release paper 6 is peeled off at the same time. .

By the way, in this embodiment, the sanitary napkin of the type in which the absorbent body 2 is interposed between the liquid-permeable sheet 3 and the liquid-impermeable sheet 1 has been described as an example. , Such as sanitary napkins with a wing, such as a sanitary napkin of a type in which a paper-encapsulated absorbent body is firmly fixed with a hot-melt adhesive on a polyethylene laminated nonwoven fabric It is applicable to all articles.
