[Embodiment]
A package for absorbent articles according to an embodiment of the present invention will be described below with reference to the drawings. Note that the configurations of the following embodiments are examples, and the present disclosure is not limited to the configurations of these embodiments.

FIG. 1 illustrates an outline of a diaper 1 packaged in a paper bag in this embodiment. The diaper 1 shown in FIG. 1 is, for example, an underpants-type disposable diaper. In the following description, the longitudinal direction is the direction connecting the front body arranged to face the abdomen of the wearer and the back body arranged to face the back of the wearer.

Further, the thickness direction of the diaper 1 means the direction in which the diaper 1 folded in two is folded as shown in FIG. 3, which will be described later. Further, the width direction of the diaper 1 means the folding direction of the diaper 1 that is folded in two with respect to the longitudinal direction of the diaper 1 as shown in FIG. Further, the depth direction of the diaper 1 means a direction perpendicular to the width direction and the thickness direction.

The width direction of the paper bag 2, which will be described later, refers to the width direction when the paper bag 1 in the state shown in FIG. Similarly, the depth direction of the paper bag 2 means the depth direction when the paper bag 2 in the state shown in FIG. It refers to the thickness direction when the paper bag 2 in the state shown in FIG. 6 is viewed from the opening direction of the opening 6 .

As shown in FIG. 1, the diaper 1 includes a crotch region 1B, which corresponds to the crotch region covering the private part of the wearer when worn, and a crotch region 1B positioned in front of the crotch region 1B and corresponding to the wearer's front body. It has a front body region 1F, which is a part, and a back body region 1R, which is a part located behind the crotch region 1B and corresponding to the back body of the wearer. Further, the diaper 1 is provided with an indicator 11 extending in the longitudinal direction in the crotch region 1B. The indicator 11 contains a material that changes color due to the adhesion of moisture, for example. Therefore, when urine adheres to the indicator 11, the indicator 11 changes color by reacting with the water contained in the urine. Note that the diaper 1 is an example of the "absorbent article" of the present disclosure.

FIG. 2 illustrates an outline of a method of manufacturing a package 100 in which the diaper 1 as shown in FIG. 1 is wrapped in a paper bag.

FIG. 3 illustrates an outline of the process of step S1. That is, in step S1, as shown in FIG. 3, a plurality of diapers 1 are arranged in the MD direction (manufacturing flow direction) at regular intervals while being folded in the longitudinal direction. Although the diaper 1 is folded in two in FIG. 3, the number of folds is not limited to two, and may be three or four. In FIG. 3, the diapers 1 are arranged with the folding direction (width direction) of the diapers 1 facing the MD direction, but the diapers 1 are arranged with the depth direction of the diapers 1 facing the MD direction. may be

(S2)
FIG. 4 illustrates an outline of the process of step S2. That is, in step S2, as shown in FIG. 4, the diapers 1 arranged at regular intervals in the MD direction in step S1 are wrapped with the shrink film 3 extending in the MD direction. Then, the shrink film 3 in which the diaper 1 is wrapped is heated to be shrunk. When the shrink film 3 shrinks in this manner, the diaper 1 wrapped with the shrink film 3 is compressed in the thickness direction. Moreover, one sheet of shrink film 3 in which the diaper 1 is wrapped in this way is shrunk to form a beaded shape.

(S3)
FIG. 5 illustrates an outline of the process of step S3. That is, in step S3, as shown in FIG. 5, the shrink film 3 shrunk in step S2 is provided with perforations 5 along the CD direction (the direction crossing the MD direction). The perforation 5 is provided between the diapers 1 arranged side by side and wrapped with the shrink film 3 .

(S4)
FIG. 6 illustrates an outline of the process of step S4. FIG. 6(A) illustrates an outline of the diaper 1 during loading. Moreover, FIG. 6(B) illustrates an outline of a paper bag 2 (an example of the “packaging body” of the present disclosure) loaded with the diaper 1 . In addition, in FIG. 6B, the diaper 1 is shown to be visible in order to explain the diaper 1 packed in the paper bag 2, but the packaged diaper 1 cannot be seen from the outside in reality. In step S4, the shrink film 3 extending in the MD direction is bellows-shaped as shown in FIG. fold into. Note that the shrink film 3 may be formed into a bellows shape by folding every other perforation 5 in the longitudinal direction. Then, the paper bag 2 is loaded with the bellows-shaped shrink film 3 and a plurality of diapers 1 wrapped in the shrink film 3 . The paper bag 2 is provided with an opening 6 for loading. Moreover, two diapers 1 packed with such a bellows-shaped shrink film 3 and the shrink film 3 are accommodated side by side in the width direction of the paper bag 2 . In addition, openings 4 (an example of the “opening portion” of the present disclosure) are provided side by side in the width direction on the upper surface of the paper bag 2 in FIG. 6(A). The width of the opening 4 is substantially the same as the width of the shrink film 3 wrapping the diaper 1 . The shrink film 3 and the diaper 1 wrapped with the shrink film 3 are loaded into the paper bag 2 so that the rear end 33 of the shrink film 3 in the loading direction faces the opening 4 .

(S5)
FIG. 7 illustrates an outline of the process of step S5. FIG. 7A illustrates a state in which the opening 6 of the paper bag 2 is sealed. FIG. 7B illustrates an outline of the paper bag 2 with the opening 6 sealed. That is, in step S5, as shown in FIG. 7A, the opening 6 is sealed by adhering the back surfaces of the paper forming the opening 6 of the paper bag 2 loaded with the plurality of diapers 1 in step S4. be stopped. Note that the end portion 33 of the shrink film 3 is positioned to face the opening 4 with the paper bag 2 sealed. Moreover, the end portion 33 extends along the thickness direction of the paper bag 2 (the opening direction of the opening 4).

[Action/effect]
According to the package 100 as described above, since the shrink film 3 that wraps the diaper 1 has a low hygroscopicity, even if the paper bag 2 absorbs moisture contained in the outside air, the shrink film wrapped in the paper bag 2 will remain closed. The film 3 prevents moisture from entering in the direction of the diaper 1. - 特許庁Therefore, discoloration of the indicator provided on the diaper 1 due to erroneous reaction with moisture is suppressed.

In addition, according to the package 100 as described above, the shrink film 3 for packaging the diapers 1 only needs to be waterproof and impermeable to water. It is possible to use a much thinner film compared to . Also, the amount of film can be reduced.

Moreover, according to the package 100 as described above, since the diaper 1 is wrapped with the shrink film 3, the frictional resistance when the diaper 1 is loaded into the paper bag 2 can be reduced. Therefore, the paper bag 2 is less likely to be damaged due to frictional force from the diaper 1 .

Further, according to the package 100 as described above, the opening 4 is provided at a position facing the end portion 33 of the shrink film 3 wrapped in the paper bag 2 . The shrink film 3 is wrapped in the paper bag 2 with the end portion 33 directed toward the opening 4 . Therefore, the shrink film 3 and the diaper 1 wrapped in the shrink film 3 can be easily removed from the opening 4 . Further, since the shrink film 3 has high smoothness, it can be said that the shrink film 3 and the diaper 1 wrapped in the shrink film 3 can be easily removed from the opening 4 . Further, since the shrink film 3 is provided with perforations 5, the required number of diapers 1 can be taken out by tearing the shrink film 3 along the perforations 5. - 特許庁Further, since the taken out diaper 1 is in a compressed state, it is not bulky and can be easily carried.

Therefore, according to the package 100 as described above, it is possible to deal with various sales methods. For example, it is possible to sell packaged products to customers in regions who prefer products that are hygienic and compact. Alternatively, for example, when the diaper 1 itself is expensive and sold in individual packages to customers in regions where it is rare to purchase the entire package, hygiene and weather resistance that are required when transporting diapers to the region can be considered. . In addition, when the diapers 1 are sold individually, it is necessary to remove the diapers 1 from the package. Therefore, the indicator 11 provided on the removed diaper 1 is prevented from erroneously reacting to moisture contained in the outside air.

By the way, as a package according to a comparative example, it is conceivable to load diapers in a compressed state in a bag made of a film such as vinyl. In such a case, it is conceivable that the diaper accommodated in the bag will spontaneously expand, but the film has a high tensile strength, so that the bag is prevented from being damaged. On the other hand, when a paper bag is used as a substitute for a bag made of a film such as vinyl, the paper bag may be damaged due to natural expansion of diapers accommodated in the bag due to the low tensile strength of the paper bag. However, according to the package 100 as described above, the diaper 1 is wrapped in the shrink film 3 while being compressed in the thickness direction (step S2). Therefore, the diaper 1 is prevented from expanding while being wrapped in the paper bag 2 . Therefore, force acting on the inner surface of the paper bag 2 from the diaper 1 is suppressed. Therefore, the paper bag 2 is prevented from being damaged while the same number of diapers 1 as can be accommodated in the bag made of a film such as vinyl can be packed.

In addition, when a plurality of diapers 1 are separately accommodated in the covering paper bag 2 with the shrink film 3 that is not connected as a package according to the comparative example, the diapers 1 (the shrink films 3) are slippery inside the paper bag 2. - 特許庁Therefore, the diapers 1 (the shrink films 3) may be out of alignment. Therefore, it is conceivable that the diaper 1 wrapped in the shrink film 3 may move to the vicinity of the loading opening 6 provided in the paper bag 2 during loading. Therefore, there is a possibility that the sealing failure of the opening 6 will occur. Further, if the diapers are displaced within the package 100 during transportation or after opening the package according to the comparative example, not only will the paper bag 2 be damaged, but the diapers will be removed from the opening 4 for taking out the paper bag 2. Retrieving 1 can be difficult.

On the other hand, according to the package 100 as described above, the diapers 1 are individually wrapped in the shrink film 3, but the shrink film 3 itself is in a connected state. Therefore, the alignment of the diapers 1 is maintained inside the paper bag 2 . Therefore, the diaper 1 wrapped with the shrink film 3 is prevented from moving to the vicinity of the opening 6 when the opening 6 is sealed. Therefore, poor sealing of the opening 6 is suppressed. Moreover, damage to the paper bag 2 during transport of the package 100 or after opening is suppressed. Further, since the alignment of the diapers 1 is maintained, the diapers 1 can be easily taken out from the opening 4 for taking out the paper bag 2 .

In addition, when a plurality of diapers are pushed into a paper bag as a package according to a comparative example, one of the diapers is delayed in the pushing direction due to friction with the inner surface of the paper bag, and remains in the vicinity of the opening for loading the package, resulting in the opening. It is conceivable that it may cause a sealing failure. However, according to the package 100 as described above, the plurality of diapers 1 are individually wrapped with the highly smooth shrink film 3 . Further, a plurality of diapers 1 are connected via shrink films 3. Therefore, when the diaper 1 is loaded into the paper bag 2 through the opening 6 , the diaper 1 passing near the inner surface of the paper bag 2 is prevented from being delayed due to friction with the inner surface of the paper bag 2 . Therefore, the diaper 1 is prevented from remaining in the vicinity of the opening 6, and as a result, sealing failure of the opening 6 can be prevented.

[Modification]
As an alternative to the shrink film 3 in the above-described embodiment, a film made of a different material having lower hygroscopicity than paper or a film made of a different material having lower water permeability than paper may be used. Alternatively, the diaper 1 may be wrapped in the paper bag 2 in a state of being wrapped with the shrink film 3 without being compressed. Further, the diaper 1 does not have to be connected to other diapers 1 while individually wrapped with the shrink film 3 . The plurality of diapers 1 may be separately loaded into the paper bag 2 . Alternatively, a plurality of diapers 1 may not be individually wrapped with one shrink film 3 but may be wrapped together. Further, the size and position of the opening 4 provided in the paper bag 2 are not limited to the examples of the above embodiments. Also, the opening 4 may not be provided. Also, the end portion 33 in the state of being wrapped in the paper bag 2 does not have to face the direction of the opening 4 . Further, instead of the perforations 5, notches or the like may be provided in the portion of the shrink film 3 between the diapers 1. FIG. Also, the perforations 5 may not be provided. Further, instead of the diaper 1, a urine pad, a sanitary product, or the like may be individually wrapped with the shrink film 3 and loaded into the paper bag 2.

The embodiments and modifications disclosed above can be combined.
