Description

Individually Wrapped Sanitary Napkins

The present invention relates to a sanitary napkin housed in a single package, and more particularly, to the napkin that can be easily taken out of the single package.

The sanitary napkin described in Japanese Unexamined Patent Publication No. 7-333l4 has first and second wings extending laterally from the flap on each side flap respectively formed at the widthwise side edge of the liquid absorbent core. The first wing is conveniently located at the front of the napkin and the second wing is conveniently located at the rear of the napkin. On the back surface of the napkin, an adhesive is applied to the widthwise center portion of the napkin and the first wings in the width direction, and the napkin can be fixed to the inner surface of the crotch region of the wearing pants by the adhesive at the center portion. The first wing is bent at the edge next to the crotch region of the pants and folded to the outer surface of the pants, and fixed to the outer surface by the adhesive. This first wing covers the side edges of the pants so that they do not soil, and also prevents deformation such as warping of the napkin. The second wing broadly covers the hip portion of the pants so that the pants do not become dirty due to the menstrual blood flowing in the wearer's hip direction. When such a known napkin is stored in a package, the first and second wings are bent inside the napkin so as to overlap with the surface sheet, and the adhesives of both first wings are covered and protected by the first release paper covered on these wings. The adhesive of the napkin center part is covered and protected by the 2nd release paper. The napkin is folded and folded three times in a forward and backward direction so that the front end is above and the rear end is below, with the surface sheet inward.

The known napkin does not move back and forth and left and right in the crotch region of the pants as the widthwise center portion is fixed to the inner surface of the wearing pants, thereby accurately capturing acupuncture points. However, since the second wing having a shape that widens in the width direction is not fixed to the pants, it may be twisted or folded due to the wearer's hip movement or the like, thereby not exerting its original function or impairing a good fit. In addition, when the napkin is worn, it is necessary to take out the napkin from the packing stand and to peel off the release paper one by one. In addition, the packing stand and the first and second release paper become separate garbage. There is a hassle to dispose of at least three wastes.

Therefore, the present invention provides a napkin having first and second wings such as the above-mentioned napkins, which is capable of easily exerting the original function of each wing and easily taking out the napkin from the packing table. Doing.

With reference to the accompanying drawings, it will be described in detail the individual packaged sanitary napkin of the present invention. In this description, when the phrase "separable" is not used formally with respect to the phrases "sticking" and "bonding", the phrases "sticking" and "bonding" usually come into contact with each other. It means that it is not intended to peel intentionally.

The individually packaged sanitary napkin shown in a perspective view in FIG. 1 consists of a napkin 2, an individual packing table 3 represented by an imaginary line, and the napkin 2 is folded and sealed with an adhesive tape 4 in a folded state. It is housed in the individual packing stand 3 which has become. The individual packing stand 3 is made of a thermoplastic plastic film, and includes longitudinal end edges 6 and 7, widthwise side edges 8 and 9, and side edges parallel to the end edges 6 and 7. The opening edge part 11 extended in the width direction between 8 and 9 is provided, and the overlapping films are joined so that peeling is mutually possible at the side edges 8 and 9.

2 and 3 are partially broken front and rear views when the napkin 2 of FIG. 1 is in a deployed state (used state) from a folded state. The napkin 2 is composed of a liquid-permeable surface sheet 12, an liquid-impermeable back sheet 13, and a liquid-absorbing core 14 interposed between these sheets 12 and 13, and wears pants (physiological pants). ), The front end portion l6 located in front of the crotch region, the rear end portion 17 located in the rear, and the middle portion 8 occupied between these two ends 16 and 17. In FIG. 2, the left surface sheet 12 of the center line C-C is removed. The front and backsheets 12 and 13 are firmly bonded to one another at portions extending from the circumferential edges of the core 14 to form the widthwise side edge flap l9 and the longitudinal end edge flaps 21 and 22. have. Each lateral edge flap 19 has a first wing 23 extending laterally at a convenient portion at the front of the napkin 2, and laterally extended at a convenient portion at the rear end of the napkin 2. It has a second wing 24.

As shown in FIG. 3, the back surface where the napkin 2 is in contact with the pants has a first adhesive region 26 located at the first wing 23, a second adhesive region 27 located at the second wing 24, and The third adhesive region 28 extending in the front-rear direction from the widthwise center portion of the napkin 2 is formed separately.

As for the napkin 2 comprised in this way, the 3rd sticking area | region 28 is fixed to the inner surface center part of the crotch region of a wearing pant, and the 1st wing 23 is bent along the widthwise side edge of the crotch region of a pant. The first adhesive region 26 is fixed to the outer surface of the pants. The second wing 24 extends on the inner surface of the hip portion of the pants, and is fixed to the inner surface of the hip portion by the second adhesive region 27. The napkin 2 fixed in this way does not shift or twist with respect to a pants.

4 and 5 are cross-sectional views taken along the line IV-IV of FIG. 1 and the opening procedure of the individual packing table 3. However, in these drawings, the napkin 2 is shown not as a sectional view but as a side view.

FIG. 6 is a plan view of a state in which a sanitary napkin individually wrapped is opened along FIG. 5 and developed from the folded state.

In the individually wrapped sanitary napkin of FIG. 6, the first and second wings 23, 24 are in a bent state over the surface sheet 12. The napkin 2 is folded at the rear end 17 of the virtual line AA with the surface sheet 12 inward in the direction of the arrow X, and superimposed on the middle 18, and sheared at the virtual line BB. The part 16 is bent in the direction of the arrow Y and is superimposed on the rear end 17 which is already bent, thereby bringing the state of FIG.

Referring to Figure 4, the structure of the sanitary napkin individually wrapped as follows. The plastic film and the napkin 2 which form the individual packing stand 3 overlap each other, are united, and are in the state folded and folded in three layers. In the napkin 2, the first adhesive region 26 is made of the first release paper 31, the second adhesive region 27 is made of the second release paper 32, and the third adhesive region 28 is made of the Each is covered and protected by the third release paper 33. The first release paper 31 is firmly adhered to the inner surface of the rear end portion 40B of the package 3 by the first hot melt adhesive 36, and the second release paper 32 is attached to the second hot melt adhesive ( 37, it adhere | attaches firmly at the site | part which overlaps with the 1st release paper 31 mutually. The 3rd release paper 33 is firmly adhere | attached at the several site | part of the inner surface of the package stand 3 by the 3rd hot melt adhesive 38. As shown in FIG. The sealing adhesive tape 4 has its base end 4A firmly adhered to the outer surface of the front end portion 40A of the single package 3 by the fourth adhesive 39, while the free end 4B is the single package. It is bonded to the outer surface of the rear end 40B of (3) so that peeling is possible. The inner surface of the individual packing stand of the site | part to which the free end part 4B is joined is also the site | part to which the 3rd release paper 33 is firmly attached by the 3rd hot melt adhesive 38. FIG. The front edge of the free end part 4B is bend | folded inward, and the adhesive tape 4 forms the non-adhesive loading part 4C. As is apparent from Figs. 4 and 6, the first release paper 31 is in a state in which the rear end portion 31A extends rearward from the rear end portion 40B of the packing stand 3 individually.

In order to open the individual packing stand 3, first, in FIG. 4, the adhesive tape 4 in which the loading part 4C was formed is pulled in the arrow P direction, and it is set as the state of FIG. In FIG. 5, the napkin front end 16 is fixed, and only the single package 3 is moved in the direction of the arrow Q, so that the third release paper 33 firmly adhered to the single package 3 is attached to the third. It peels from the adhesion area | region 28. FIG. When the third release paper 33 is continuously peeled off toward the rear end, the first release paper 31 firmly adhered to the package 3 and the second release paper 31 firmly adhered to the first release paper 31. (32) can be peeled off continuously. However, the opening order of the single packing stand 3 is not limited to this. According to the napkin user, in the state of FIG. 5, before the third peeling paper 33 starts to be peeled off from the napkin front end 16, the napkin rear end 17 is individually rear end 40B of the packing table 3. At the same time as the arrow R, and the napkin 2 and the individual packing stand 3 are brought into the unfolded state of FIG. 6, and then the third release paper 33 starts to be peeled off from the front end 16 of the napkin. There is a case. In this case, in the sanitary napkin housed in this single packing stand, the rear end part 31A of the 1st release paper 31 extended backward by the back end part 40B of the single packing stand 3 is hand-held, By pulling, the napkin 2 and the single packing table 3 can be moved quickly in the direction of the arrow R. As shown in FIG.

Napkins may use 5-50 micron, relatively thin stretched plastic film, but such films are difficult to hold by hand when opening, and are particularly difficult to hold by hand when the film is being charged. The opening of the bag has taken time. Therefore, in the sanitary napkin housed in this single packing stand, the sheet material which is higher rigidity than the film which comprises the single packing stand 3 as the 1st release paper 31 is used, More preferably, it does not charge easily. . Since the rear end portion 40B of the first release paper 31 made of such a material can be easily pulled off by hand, it does not take time to open the individual packing stand.

7 and 8 are diagrams similar to FIG. 6 showing an embodiment of the present invention. In the sanitary napkin accommodated in the single packing stand of FIG. 7, one 4th release paper 51 is used instead of the 1st, 2nd release papers 31 and 32 of FIG. Since the fourth release paper 51 has one surface as a coating surface for the first adhesive region 26 and the other surface as a coating surface for the second adhesive region 27, the fourth release paper 51 51) both surfaces thereof should be easily peeled off with respect to the adhesive region. In addition, one side of this peeling surface becomes a surface firmly adhere | attached to the inner surface of the packing stand 3 individually. In each of the first and second release papers 31 and 32 of FIGS. 5 and 6, one surface is a surface covering the first and second adhesive regions, and the other surface is the first and second release papers ( 31 and 32 are different from the fourth release paper 51 in that the surfaces are firmly adhered to each other or to the packing table 3.

In the individually packaged sanitary napkin of Fig. 8, one relatively long fifth release paper 52 is used instead of the first and second release papers 31 and 32. The fifth release paper 52 may be a surface on which one surface covers the first and second adhesive regions 26 and 27, and may also be a surface that is firmly adhered to the inner surface of the package 3. As an arrangement | positioning space of the 1st and 2nd vanes 23 and 24 like an example of illustration, the usage-amount of release paper may increase compared with FIG. 5 or FIG.

In the individually packaged sanitary napkin of the present invention, since the second adhesive region is formed on the second wing covering the hip of the wear pants, the positional shift and the twist of the second wing can be prevented. The first and second adhesive regions formed separately on each of the first and second vanes are covered and protected by separate first and second release papers, respectively, and the first and second release papers are firmly adhered to each other and 1 By releasing the release paper firmly to the package, the operation of opening the package and the peeling operation of the first and second release papers are carried out continuously. Since the first release paper was formed by using a sheet material that is more rigid than the plastic film of each package, the red end portion was formed by extending the rear end portion of the release paper from the rear end portion of the individual packaging pieces to the rear. It becomes possible to open the package immediately. Since the individual packaging stand and the release paper are peeled off from the napkin in a state where they are firmly bonded together, it does not take time to dispose it as garbage.
