[0014] [Auxiliary absorbent] The auxiliary absorbent core of the present invention is attached to a sanitary napkin to assist in the absorption of body fluids, and is characterized by being formed in a rod shape.

[0015] The auxiliary absorbent body is formed in a rod-like shape, so that it fits closely along the crotch area of ​​the user, preventing menstrual blood leakage and maintaining a good contact state.

[0016] The length of the auxiliary absorbent body is preferably 2 to 15 cm, more preferably 3 to 10 cm, and even more preferably 4 to 7 cm. The diameter of the auxiliary absorbent body (diagonal in the case of a polygonal cross section) is preferably 0.3 to 3 cm, more preferably 0.4 to 2 cm, and even more preferably 0.5 to 1.5 cm. A size within this range allows it to be held in one hand and is easy to handle when placed in a sanitary napkin. Furthermore, this size allows it to be easily stored in the packaging container for the container-packaged auxiliary absorbent body described below, and it offers excellent storage and portability.

[0017] Examples of the cross-sectional shape of the auxiliary absorbent body include a circle, an ellipse, a polygon, a semicircle, a semi-ellipse, and a semi-polygon.

[0018] The material of the auxiliary absorbent body is not particularly limited as long as it has water-absorbing properties, and examples thereof include water-absorbent polymers, natural fibers, synthetic fibers, biodegradable polymers, etc. The auxiliary absorbent body is preferably made of a material that can be flushed down the toilet.

[0019] The absorption capacity of the auxiliary absorbent body can be appropriately set by changing its size and material. For example, if the auxiliary absorbent body is made of cotton-like pulp, the absorption capacity can be increased or decreased by changing the size and pulp concentration.

[0020] As described below, the auxiliary absorbent is contained in the storage compartment of the sanitary napkin and does not come into direct contact with the skin, and therefore may contain a functionality-imparting agent that imparts a predetermined function. Examples of functionality-imparting agents include deodorants, fragrances, deodorizing agents, antibacterial agents, cooling agents, moisture-absorbing agents, and warming agents. The auxiliary absorbent preferably contains a deodorant or fragrance.

[0021] [Auxiliary absorbent pad in a package] The auxiliary absorbent body in a package of the present invention is characterized in that a plurality of auxiliary absorbents, which are attached to a sanitary napkin and assist in absorbing body fluids, are contained in a package.

[0022] A plurality of auxiliary absorbent bodies in a package can be stored and carried together in the package.

[0023] The auxiliary absorbent core contained in the packaged auxiliary absorbent core can have the same configuration as the auxiliary absorbent core described above, and although a rod-shaped form is preferred, it may also be in a shape other than a rod, such as a sphere or a sheet. A sheet-shaped core can be rolled into a rod when in use.

[0024] Preferred embodiments of auxiliary absorbents housed in a packaging container include a plurality of auxiliary absorbents of the same type housed in the packaging container, and a plurality of auxiliary absorbents of different types housed in the packaging container. Examples of types include size, absorption capacity, shape, etc. Specific examples include a embodiment in which the plurality of housed auxiliary absorbents have the same absorption capacity, and a embodiment in which the plurality of auxiliary absorbents have different absorption capacities. An embodiment in which the plurality of auxiliary absorbents have different absorption capacities may be a embodiment in which all of the auxiliary absorbents have different absorption capacities, but a preferred embodiment is a embodiment in which two to four different absorption capacities are housed in the packaging container.

[0025] The shape of the packaging container is not particularly limited as long as it can store multiple auxiliary absorbents, but examples include a box shape (see Figure 2). Examples of the shape of the packaging container include cylindrical and rectangular containers.

[0026] When a plurality of rod-shaped auxiliary absorbent bodies are stored in a box-shaped packaging container, the number of rod-shaped auxiliary absorbent bodies stored is preferably 2 to 20, more preferably 3 to 15, and even more preferably 5 to 10.

[0027] [Sanitary napkins] The sanitary napkin of the present invention is a sanitary napkin comprising a water-permeable topsheet, an absorbent material that absorbs bodily fluids, and a water-impermeable backsheet, and is characterized in that it also comprises a storage compartment that accommodates a rod-shaped auxiliary absorbent that assists in absorbing bodily fluids, and an inlet for the storage compartment is provided on the topsheet. Here, "the inlet for the auxiliary absorbent is provided on the topsheet" excludes cases in which the auxiliary absorbent is introduced from the side of the sanitary napkin, and refers to the provision of an inlet that allows the auxiliary absorbent to be introduced from above the topsheet. Specifically, for example, in addition to cases in which the inlet is formed on the topsheet itself, this also includes cases in which the inlet is formed on a member attached to the topsheet, for example, when the storage compartment is provided on the upper side of the topsheet.

[0028] By attaching the auxiliary absorbent body described above to a sanitary napkin, the absorption capacity can be easily increased. Furthermore, since the rod-shaped auxiliary absorbent body is securely housed in the housing, it can be prevented from falling off or shifting. Furthermore, the rod-shaped auxiliary absorbent body is raised, fitting snugly against the user's crotch, preventing menstrual blood leakage and maintaining good contact, resulting in an excellent wearing comfort.

[0029] The topsheet, absorbent material, and backsheet may have the same configuration as conventionally known sanitary napkins. Examples of the type of sanitary napkin include winged napkins, wingless napkins, and shorts-type napkins.

[0030] (Storage section) The storage section has a predetermined space capable of storing a rod-shaped auxiliary absorbent body, and is provided on the topsheet (skin-contacting surface) side at a position corresponding to the user's vulva. By storing the auxiliary absorbent body in such a storage section, the auxiliary absorbent body adheres closely to the user's crotch during use, making it less likely to fall off or slip out of place. An inlet for the auxiliary absorbent body is preferably provided on the topsheet so that it can be easily introduced from the topsheet side.

[0031] The storage section may be configured to store one auxiliary absorbent body in its specified space, or may store multiple auxiliary absorbent bodies, but it is preferable that it store one auxiliary absorbent body.

[0032] The material of the storage section is not particularly limited as long as it is water-permeable, and examples thereof include water-permeable surface sheets, nonwoven fabrics, and papers.

[0033] The storage section may be provided on the upper side of the topsheet or on the lower side of the topsheet. Examples of the inlet for the auxiliary absorbent body include a slit and an opening.

[0034] Examples of embodiments in which the storage section is provided above the topsheet include an embodiment in which the storage section is a rod-shaped body storage space formed by bonding the periphery of a sheet member placed on top of the topsheet, and the inlet for the auxiliary absorbent body is formed as a slit in the sheet member (see Figure 5), and an embodiment in which the storage section is a rod-shaped body storage space formed by bonding the periphery of a sheet member placed on top of the topsheet except for a small portion, and the inlet for the auxiliary absorbent body is a pocket-like space formed from an opening in the sheet member that is not bonded (see Figure 7).

[0035] An example of an embodiment in which the storage section is provided below the topsheet is one in which the storage section is a rod-shaped body storage space formed between the topsheet and the absorbent material, and an inlet for the auxiliary absorbent body is formed as a slit in the topsheet. For example, the rod-shaped body storage space may be formed by stacking a sheet member below the topsheet and fixing the periphery, or the rod-shaped body storage space may be formed directly between the topsheet and the absorbent material.

[0036] [Sanitary napkin set] The sanitary napkin set of the present invention is characterized by comprising the auxiliary absorbent body and the sanitary napkin described above.

[0037] A sanitary napkin set consists of one auxiliary absorbent body attached to one sanitary napkin. When the menstrual flow is light, the set can be used without the auxiliary absorbent body, and when the menstrual flow is heavy, the set can be attached to easily increase the absorption capacity.

[0038] [Sanitary napkin kit] The sanitary napkin kit of the present invention is characterized by comprising the auxiliary absorbent body in a packaged container as described above, and a plurality of the above-mentioned sanitary napkins.

[0039] The sanitary napkin kit can easily increase the absorption capacity by attaching an auxiliary absorbent body stored in a packaged auxiliary absorbent body to the sanitary napkin. For example, by selecting one auxiliary absorbent body from a packaged auxiliary absorbent body containing multiple auxiliary absorbents with different absorption capacities and attaching it to the sanitary napkin, it can flexibly respond to usage situations such as sports or sudden changes in menstrual blood flow.

[0040] Hereinafter, one embodiment of the auxiliary absorbent body and sanitary napkin of the present invention will be specifically described with reference to the drawings, but the present invention is not limited to this embodiment.
