Description

TECHNICAL FIELD The present invention relates to an absorbent article individual package.

Absorbent articles generally include a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body disposed therebetween. is attached to the underwear.

The work of replacing a used absorbent article (hereinafter also referred to as "used article") with a new absorbent article (hereinafter also referred to as "new article") is usually performed after removing the used absorbent article from the underwear with both hands. This is done by putting the finished product in a new packaging bag or the like, disposing of it, and attaching the new product to the underwear. At this time, when the used product is removed, the fingers are in direct contact with the used product, so body fluids easily adhere to the fingers. In addition, when a used product that has been swollen and/or deformed by absorbing bodily fluids is stored in a new packaging bag, part of the used product may get caught in the cut edges of the packaging bag and stain fingers with bodily fluids. Sometimes. In addition, even if the used product is stored in a packaging bag or the like, the used product cannot be sealed, and body fluids may leak out along the inner surface of the packaging bag and adhere to clothes.

In addition, some people wrap used items in toilet paper instead of packaging bags and throw them away. Also, some of the body fluids in the used product may leak out, causing the packaging to break, or the body fluids to drop onto the floor of the toilet compartment. Thus, there is a demand for an absorbent article individual package that allows used articles to be cleanly replaced with new ones without soiling fingers or the toilet compartment with bodily fluids, and that allows the used articles to be sealed. has been proposed.

Patent Document 1 discloses an absorbent article, a packaging sheet for individually packaging the absorbent article, one end of which is detachably attached to the surface of the packaging sheet, and the other end of which is joined to the longitudinal end of the packaging sheet. The adhesive tape has a first adhesive layer, a first base material, a second adhesive layer, and a second base material laminated in this order, and the first base material and the second base material are laminated. A package for absorbent articles is disclosed which further has a connecting portion for connection (Claim 1).
In the adhesive tape, the first adhesive layer and the first base material bonded thereto are detachably attached to the non-skin side of the packaging sheet by the first adhesive layer, and the second adhesive layer and the second adhesive layer are bonded to this The second base material is releasably attached to the non-skin side of the first base material by the second adhesive layer, and the second adhesive layer temporarily attaches the package of the absorbent article to the wall or the wearer's body. It becomes an adhesive layer for sticking to (paragraphs 0036 to 0037).
According to Patent Document 1, the second adhesive layer and the second base material are peeled from the adhesive tape starting from the connection part, and the second adhesive is connected to the packaging sheet and the absorbent article via the first base material. Exposing the layer, affixing this second adhesive layer to the wall of the toilet compartment or to the wearer's body to secure the absorbent article from falling to the floor, use both hands to remove the used absorbent article. After that, only the absorbent article fixed above is removed and attached to the underwear (Paragraph 0015, Paragraph 0053).

Even in this case, if body fluids are visible through the used packaging sheet 6, it is not appropriate in terms of concealability, and it is preferable to adopt highly opaque nonwoven fabric so as to hide stains of body fluids. It is from.
By using the pulp-containing composite nonwoven fabric having such opacity as the used packaging sheet 6, the ability to conceal the absorbent article 50 in the individual package 1 is remarkably improved. If the opacity is less than 75%, the concealability of the absorbent article 50 enclosed in the individual package 1 tends to deteriorate. Opacity is a value measured based on JIS P 8148:2018 (ISO2470-1:2016).

The pulp-containing composite nonwoven fabric includes a nonwoven fabric and a wood pulp layer laminated on at least one surface of the nonwoven fabric. A preferred embodiment of the pulp-containing composite nonwoven comprises a nonwoven and a wood pulp layer integrated with at least one surface of the nonwoven. Here, "integrated" means that the nonwoven fabric and the wood pulp layer are not separated from each other even partially before and after the use of the absorbent article 1, so that the function is not significantly reduced. The basis weight of the nonwoven fabric is preferably 7 g/m ² or more and 30 g/m ² or less, and the basis weight of the wood pulp layer is preferably 30 g/m ² or more and 70 g/m ² or less. is preferably 30 g/m ² or more and 80 g/m ² or less from the viewpoint of opacity, strength, absorption of body fluids, and the like. By setting the basis weights of the nonwoven fabric and the wood pulp layer within the above ranges, it becomes easy to adjust the basis weight of the pulp-containing composite nonwoven fabric within the above ranges. By setting the basis weight of the pulp-containing composite nonwoven fabric within the above range, it becomes easier to obtain an opacity of 75% or more.

Among the pulp-containing composite nonwoven fabrics, a hydroentangled integrated product is preferable. The integrated product is, for example, a pulp-containing composite nonwoven fabric obtained by entangling wood pulp fibers with a water jet without using a binder on the surface of the nonwoven fabric and integrating them to form a wood pulp layer. In such a pulp-containing composite nonwoven fabric, the fibers constituting the nonwoven fabric and the wood pulp fibers are entangled on one surface of the nonwoven fabric to integrate the wood pulp layer, and a part of the wood pulp fibers spreads through the nonwoven fabric in the thickness direction. The nonwoven fabric and the wood pulp layer are extremely strongly bonded to each other.

Here, the nonwoven fabric is not particularly limited, and various nonwoven fabrics can be used, but a spunbond nonwoven fabric is preferred. As the spunbond nonwoven fabric, nonwoven fabrics produced by a spunbond method, a melt blow method, a flash spinning method, or the like can be used without particular limitation. Synthetic resins such as polyethylene, polypropylene and polystyrene are preferably used. A spunbond nonwoven may comprise a plurality of synthetic resin fibers. Among these, a spunbond nonwoven fabric made of polypropylene is preferable from the viewpoint of strength, softness, absorbency, and the like. The wood pulp fibers that make up the wood pulp layer are not particularly limited. ). Wood pulp fibers can be used singly or in combination of two or more.

The weight ratio of the nonwoven fabric to the wood pulp layer (nonwoven fabric/wood pulp layer) is preferably 40/60% by weight or more and 10/90% by weight or less. If the content of the wood pulp layer is less than 60% by mass, a pulp-containing composite nonwoven fabric that is stable in terms of body fluid absorption tends not to be formed. It tends to be difficult to use as a used packaging sheet 6.

In the individual package 1 of the present embodiment, the pulp-containing composite nonwoven fabric is preferably arranged so that the wood pulp layer is on the outer surface of the individual package 1 . In this configuration, the spunbonded nonwoven fabrics face each other inside the individual package 1 . As will be described later, when both ends 25a and 25b (FIG. 4) in the width direction of the individual package 1 are sealed, the spunbonded nonwoven fabric faces each other to increase the sealing efficiency and reduce the defective product rate. is obtained. Moreover, since the wood pulp layer has good body fluid absorbability, even if body fluid leaks from the absorbent article 50 after use, the wood pulp layer can prevent further leakage of body fluid.

As mentioned above, the pulp-containing composite nonwoven fabric has a high opacity. Table 1 below shows a comparison between the opacity of the commercially available packaging sheet and the opacity of the pulp-containing composite nonwoven fabric. When the packaging sheet for commercial products is made of cloth, its opacity is measured based on JIS L 1912. As for the pulp-containing composite nonwoven fabric, the basis weight of the entire composite nonwoven fabric is 55 g/m ² , the basis weight of the wood pulp layer is 43 g/m ² , and the basis weight of the spunbond nonwoven fabric is 12 g/m ² . , which consisted of 79% by weight of wood pulp layer and 21% by weight of spunbond nonwoven fabric. From Table 1, it can be seen that the pulp-containing composite nonwoven fabric has a significantly higher opacity than the packaging sheets (films and spunbond nonwoven fabrics) used for conventional individual packages.

(Structure in which antibacterial nonwoven fabric is included in the used packaging sheet)
By using the antibacterial nonwoven fabric for part or all of the used packaging sheet 6, the propagation of germs is prevented, so that the generation of odors caused by the propagation of germs can be reduced, and the work of replacing the absorbent article 50 can be reduced. It can be implemented hygienically and safely. For example, the used packaging sheet 6 is made of resin film, paper, or antibacterial nonwoven fabric. From the viewpoint of strength and workability, the basis weight of the used packaging sheet 6 is in the range of, for example, 15 g/m ² or more and 50 g/m ² or less when it is a resin film, nonwoven fabric, or antibacterial nonwoven fabric. In some cases, it is, for example, in the range of 30 g/m ² or more and 70 g/m ² or less.

Examples of antibacterial nonwoven fabrics include nonwoven fabrics containing antibacterial fibers having an antibacterial activity of 2.0 or more as a main component and also containing other fibers, nonwoven fabrics made of antibacterial fibers having an antibacterial activity of 2.0 or more, and the like. be done. "Containing as a main component" means containing more than 50% by weight of the whole. Examples of fibers that can be contained in addition to the antibacterial fibers include synthetic fibers made of synthetic resins such as polypropylene and polyethylene, regenerated fibers such as rayon, and natural fibers such as cotton.

The antibacterial fiber is not particularly limited as long as it is a fiber having antibacterial properties, but it is preferable to use a fiber obtained by kneading an inorganic antibacterial agent into a synthetic fiber. As the inorganic antibacterial agent, inorganic compounds containing antibacterial metal ions such as silver, copper, and zinc can be used without particular limitation. Inorganic porous materials such as hydroxyapatite, clay minerals, alumina, silica, and bentonite are included. An inorganic antibacterial agent can be used individually by 1 type or in combination of 2 or more types. The antibacterial fiber can be produced, for example, by adding one or more inorganic antibacterial agents to a synthetic resin in a molten state, kneading the mixture, and then spinning the synthetic resin. Here, examples of synthetic resins to be blended with inorganic antibacterial agents include polyester resins such as polyester and polyethylene terephthalate, polyolefin resins such as polyethylene and polypropylene, polyacrylamide, polyvinyl alcohol, crosslinked polyvinyl alcohol, ethylene vinyl acetate copolymer, Polyvinyl formal etc. are mentioned. The amount of the inorganic antibacterial agent to be blended with the synthetic resin is, for example, 100 wt. % in the range of 0.005% by weight or more and 0.5% by weight or less.
For example, using Staphylococcus aureus and Escherichia coli according to the JIS L 1902 fungal liquid absorption method, conducting an antibacterial test using a standard cloth (cotton cloth) as a control, the obtained antibacterial activity value is 2.0 or more. Use antibacterial fabric. Here, the antibacterial activity value is measured according to the JISL1902 bacterial liquid absorption method.
