Description

The present invention relates to an individual package of an absorbent article.

In recent years, individual packaging of an absorbent article in which an absorbent article containing a fragrance is wrapped with a packaging material has been proposed (for example, Patent Documents 1 and 2).
In Patent Document 1, an absorbent article is packaged with a packaging material by folding a package, and an individual packaging of the absorbent article in which a fragrance is applied to a predetermined area where the surfaces of the folded packaging materials face each other. The body is disclosed.

Further, Patent Document 2 applies a fragrance having a coating step of applying a fragrance to an absorbent article and a folding step of folding the absorbent article to which the fragrance is applied in a valley fold shape at least once in the longitudinal direction. A method for producing an individual package of an absorbent article is disclosed.

However, in the individual packaging of the absorbent article described in Patent Document 1, the fragrance is not applied to the absorbent article, but the fragrance is applied to the region where the surfaces of the packaging materials face each other, so that the fragrance is scented. It is easy to volatilize, and the fragrance weakens if the storage period is long. In addition, since the scent is easily volatilized, there is a high possibility that the odor will be transferred to other products when the product in which the individual package is packaged is displayed at the store.

Further, Patent Document 2 describes a position where the fragrance is stably applied when the packaging body for packaging the absorbent article to which the fragrance is applied is bent, and a means for preventing contamination of the production line due to the application. However, there is no description as to where the fragrance should be applied to the individual packaging of the absorbent article to make it difficult for the fragrance to volatilize.

Therefore, the present invention is to provide an individual package of an absorbent article that can eliminate the drawbacks of the above-mentioned prior art.

The present invention comprises an absorbent article having a vertical direction corresponding to the front-back direction of the wearer and a horizontal direction orthogonal to the vertical direction and having an absorbent body, and a packaging material for packaging the absorbent article. A first layer in which the packaging material is detachably adhered to the clothing side surface of the absorbent article via an adhesive portion and crosses the laminate laterally with the skin side surface of the absorbent article inside. An individual package of an absorbent article having a structure in which the absorbent article is vertically folded by a folding line and a second bending line, and the absorbent article is the absorbent body or the absorbent article. It has a fragrance arrangement region extending in the vertical direction inside the article, and the laminate is located in the central region sandwiched between the first bending line and the second bending line, and on both sides in the vertical direction with the central region sandwiched. It is divided into a first folding region extending from the first folding line and a second folding region extending from the second folding line, and the second folding region is on the first folding region on the central region. The tips of the second fold region in the fragrance arrangement region are overlapped and coincide with the tip of the first fold region in a plan view, or the second fold line side of the tip of the first fold region. It provides an individual package of absorbent articles arranged in.

According to the present invention, it is difficult for the scent to volatilize from the individual package, and the scent is unlikely to weaken during the storage period.

As shown in FIG. 2, the individual body 100 of the liner 1 according to the embodiment of the present invention described above has a fragrance arrangement region KT formed by applying a fragrance to the liner 1. Therefore, in the individual package 100, the scent is unlikely to weaken even if the storage period is long. Further, the vertical X tip KTb of the fragrance arrangement region KT located in the second folding region 10B is arranged on the second folding line IL2 side of the vertical X tip 1a of the first folding region 10A. Therefore, it is difficult for the scent of the liner 1 to volatilize to the outside of the individual packaging body 100. Therefore, when a product in which the individual package 100 is packaged is displayed at the store, it is possible to prevent the odor from being transferred to another product. Further, in the individual packaging body 100, the scent is less likely to be weakened even if the storage period is long, and the scent of the liner 1 is less likely to be volatilized to the outside of the individual packaging body 100.

Therefore, the long-term storage stability of the individual package 100 is improved. Further, since at least one of the deodorant and the antibacterial agent is substantially arranged on the entire surface of the absorber 4 in a plan view, the liner 1 is used after opening the individual package 100. When this happens, the odor of the body fluid transferred to the absorber 4 can be efficiently suppressed with a deodorant or an antibacterial agent. Further, in the liner 1, the fragrance arrangement region KT is arranged closer to the surface sheet 2 side in the thickness direction Z of the absorber 4, so that when the liner 1 is used after opening the individual package 100, the liner 1 is used. , The fragrance from the surface sheet 2 is highly volatile. Further, when the liner 1 is used after opening the individual body 100, in the liner 1, as shown in FIGS. 4 and 5, a pressing portion 8 extending from the surface sheet 2 to the second sheet 5 is provided in the intermediate region 1C. Since it is arranged intermittently, the wearer's body fluid can be quickly absorbed from the surface sheet to the second sheet 5 via the recessed pressing portion 8, and the body fluid can be quickly transferred to the absorber 4 while being diffused by the second sheet 5. ..

Further, since the fragrance arrangement region KT extends to the vertical X tip 4b of the second folding region 10B in the absorber 4, the fragrance is less likely to be further weakened in the individual package 100 even if the storage period is long.
Further, the vertical X tip 4b of the second folding region 10B in the absorber 4 is the first folding region 1
Since it is arranged on the second bending line IL2 side with respect to the vertical direction X tip 1a of 0A, the scent of the liner 1 is less likely to be volatilized to the outside of the individual body 100.

From the viewpoint of ensuring that the above effects are more reliably achieved, the individual body 100 having the liner 1 preferably has one or more of the following configurations.

The basis weight per absorbent sheet forming the absorber 4 is not particularly limited and may be appropriately set according to the use of the absorbent article, but when used for the liner 1, it is preferably 15 g / m ^2. Above, more preferably 20 g / m ² or more, preferably 50 g / m ² or less, still more preferably 40 g / m ² or less.

Above, more preferably 0.1 mm or more, preferably 2 mm or less, still more preferably 1 mm or less. Unless otherwise specified, the thickness of the absorbing sheet per sheet means the thickness measured by the following method ( ^{thickness under a load of 0.5 cN / cm 2} (= 0.05 kPa)).

<Measuring method of sheet thickness>
A circular plate weighing 2.5 g and having a radius of 12.5 mm is placed on the measuring table, and the position of the upper surface of the circular plate in that state is set as the measurement reference point P1. Next, the circular plate is removed, the object to be measured is placed on the measuring table, the circular plate is placed again on the measuring table, and the position of the upper surface of the circular plate in that state is defined as position P2. A laser displacement meter (CCD laser displacement sensor LK-080 manufactured by KEYENCE CORPORATION) is used as the measuring device. The difference between the reference point P1 and the position P2 is defined as the thickness of the object to be measured, that is, the thickness of the absorber ^{under a pressure of 0.5 cN / cm 2} (= 0.05 kPa).

The basis weight of the packaging material 21 constituting the individual packaging body 100 is not particularly limited and may be appropriately set according to the storage period of the individual packaging body 100 and the like, but when used for the liner 1, it is preferably 18 g / m. ^{It is 2} or more, more preferably 20 g / m ² or more, and preferably 40 g / m ² or less, still more preferably 30 g / m ² or less.

Although it extends to the position of the tip 4b of the second folding region 10B of 4, the tip KTb on the second folding line IL2 side of the fragrance arrangement region KT is larger than the tip 21b of the second folding region 10B in the packaging material 21. It suffices if it is arranged inward. That is, even if the tip KTb on the second bending line IL2 side of the fragrance arrangement region KT exceeds the second bending line IL2, it does not have to extend to the position of the tip 4b of the absorber 4, and the second bending line IL2 It does not have to exceed.

Even if the position of the tip KTb on the second folding line IL2 side of the fragrance arrangement region KT is unknown, in the absorber 4 having the fragrance arrangement region KT extending in the vertical direction X, the second folding region 10B in the absorber 4 If the tip 4b is arranged inward of the tip 21b of the second folding region 10B in the packaging material 21, the same effect as that of the individual body 100 of the liner 1 shown in FIG. 2 can be obtained. Further, if the tip 4b of the second folding region 10B in the absorber 4 is arranged inward from the tip 21a of the first folding region 10A in the packaging material 21, the storage period in the individual packaging body 100 Even if the length is long, the scent is less likely to be weakened, and the scent of the liner 1 is less likely to be volatilized to the outside of the individual packaging body 100.

Further, as shown in FIG. 2, in the individual package 100 of the liner 1 described above, the position of the tip 1b of the second folding region 10B of the liner 1 is inside the tip 21b of the second folding region 10B in the packaging material 21. Although it is arranged on the side, it has a configuration that extends outward beyond the tip 21a of the first folding region 10A in the packaging material 21. With respect to such a configuration, the position of the tip 1b of the second folding region 10B of the liner 1 is arranged inward from the tip 21b of the second folding region 10B in the packaging material 21, and further, the first folding in the packaging material 21 is arranged. It may be arranged inward from the tip 21a of the region 10A. With such a configuration, the liner 1 having the fragrance arrangement area KT can be completely accommodated inside the packaging material 21, so that the scent is further weakened in the individual package 100 even if the storage period is long. It is difficult, and the scent of the liner 1 is more difficult to volatilize to the outside of the individual packaging body 100.

Further, as shown in FIG. 5, the liner 1 of the individual package 100 described above has a fragrance arrangement region KT extending in the vertical direction X in the absorber 4, but the fragrance arrangement region KT is provided inside the liner 1. You just have to have it. For example, in the liner 1, instead of arranging the fragrance arrangement region KT on the absorber 4, the fragrance arrangement region KT may be arranged on the second sheet 5, or the fragrance arrangement region KT may be arranged on the surface sheet 2.

Further, in the liner 1 of the individual package 100 described above, as shown in FIG. 2, the absorber 4 is formed of a sheet-shaped absorbent sheet, and the absorber 4 is loaded with hydrophilic fibers such as pulp fibers. An absorbent core which is a fiber-absorbed core or a mixed product in which particles of a water-absorbing polymer are retained in the fiber may be coated with a core wrap sheet.

Further, from the viewpoint of improving absorbency and leakage resistance, a leakage prevention groove (round embossing) in which the surface sheet 2, the second sheet 5 and the absorber 4 are integrally compacted is provided on the skin side surface of the liner 1. It may be formed.
Further, as shown in FIG. 2, the liner 1 has a second sheet 5 between the surface sheet 2 and the absorber 4, but the liner 1 does not have to have the second sheet 5.

Further, as shown in FIG. 2, the individual package 100 of the liner 1 described above is provided with a fastening tape, which is a fastening portion 41, on the vertical X tip side 21b of the packaging material 21 in the second folding region 10B. Although it is sealed, instead of the adhesive tape, a hot melt adhesive or the like is adhered to the surface of the tip side 21b of the packaging material 21 of the second folding region 10B facing the packaging material 21 of the first folding region 10A. It may be sealed by applying an agent.
