Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a so-called sanitary napkin for absorbing and retaining menstrual blood.

[0002]

[Prior Art]

 Conventionally, sanitary napkins are coated with a pressure-sensitive adhesive that adheres the skin-contacting surface of the napkin to the skin in order to prevent the menstrual blood from leaking due to the napkin moving when using the napkin. Are known (see Japanese Utility Model Laid-Open Nos. 52-145099 and 63-20817).

[0003]

[Problems to be solved by the device]

 In the above-mentioned known napkin, since the adhesive is directly applied to the skin contact surface, the adhesive layer is generally extremely thin, and the layer itself has substantially a cushioning property (softness) in the thickness direction. It should not have elasticity). For this reason, it is difficult for the napkin to conform to the uneven curved surface of the local portion with which it comes into contact and to adhere closely.

In addition, when this type of pressure-sensitive adhesive is peeled off after adhering to the skin, fat adheres to the adhering surface, so when re-adhering, the adhesive force is significantly reduced, and the napkin and the skin are relatively less. However, if they move, they are very easily separated from each other.

Therefore, it cannot be said that the above-mentioned known napkin can sufficiently achieve the intended purpose.

The present invention has an object to provide a fastening means for a napkin with the adhesive, and how to configure the fastening means to eliminate the drawbacks of the known napkin. To do.

[0007]

Means for Solving the Problems The present invention for solving the above-mentioned problems comprises an absorbent body interposed between a skin contact surface and a non-skin contact surface, and at least the center of the skin contact surface. It is assumed that the sanitary napkin has adhesive means applied to both sides of the area to provide a fastening means for the skin.

The fastening means is provided by applying an adhesive to the upper surface of a strip-shaped hydrophobic flexible elastic member joined along the both side portions.

[0009]

[Action]

 In the napkin according to the present invention having the above-mentioned structure, the fastening means positioned on both sides of the skin contact surface is adhered to the local skin. The adhesive on the fastening means is supported by the flexible member so that it will fit and fit closely to the uneven surface of the skin on the skin, and its adhesive stability will be obtained, so that the napkin will come into contact with the predetermined position. Hold securely.

Even if the adhesive on the fastening means separates from the skin for some reason, as long as the fastening means is in contact with the skin, the flexible member projecting from the skin contact surface has a lateral direction of menstrual blood. It acts as a barrier to spills to.

【Example】

 An embodiment of the napkin according to the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the napkin covers the absorbent body 1 from the lower surface to the upper portions on both sides thereof with a liquid-impermeable sheet 2, and further from the upper surface to the lower surface of the laminated body to the liquid-permeable sheet 3. The sheet 3 is covered with, and the longitudinal end portions 4 of the sheet 3 are intermittently fusion-bonded to each other to form a flat vertical rectangle having a skin contact surface 5 and a non-skin contact surface 6.

As shown in FIGS. 1 to 3, a strip-shaped hydrophobic flexible elastic member 7 is provided on both sides of the skin-contacting surface 5 while leaving the longitudinal both ends slightly. And the known pressure-sensitive adhesive 9 is applied to the upper surface thereof to form the fastening means 10. It is preferable that the flexible member 7 is formed of an independent foam having a high cushioning property, such as polyurethane, polystyrene, or rubber, to have a thickness of 0.3 to 10 mm and a width of 1 to 15 mm. Although not shown, the upper surface of the pressure sensitive adhesive 9 is covered with a known release protective piece, and the release protective piece is peeled from the pressure sensitive adhesive 9 when the fastening means 10 is used.

In the napkin shown in FIG. 4, the upper surface of the absorbent body 1 is covered with the liquid-permeable sheet 3, the upper and lower sides of the laminated body are covered with the liquid-impervious sheets 2, and the upper and lower sides thereof are covered. Fastening means 10 is provided on the seat portion 2a located.

In the napkin shown in FIG. 5, a so-called medium-high napkin is constructed by arranging the second absorbent body 11 which is long in the longitudinal direction at the center of the napkin having the same configuration as the napkin shown in FIG. The absorber 11 and the fastening means 10 are combined to improve the effect of preventing the napkin from slipping.

In the napkin shown in FIG. 6, fastening means 10 is provided at both corners on both sides of the napkin having the same configuration as the napkin shown in FIGS.

In the napkin shown in FIG. 7, the fastening means 10 is provided not only on both sides of the skin contacting surface 5 but also on one longitudinal end (rear end) of the skin-contacting surface 5, so that the fastening means 10 can be fitted. The barrier function range for the lateral flow of blood is enlarged. Of course, the fastening means 10 may be provided at the other end in the vertical direction, that is, provided in an annular shape to further increase the range. In any case, if the fastening means 10 is provided at least on both sides of the skin contact surface 5, the intended purpose can be achieved.

Absorbents 1 and 11 are pulverized pulp mixed with superabsorbent polymer particles, liquid-permeable sheet 3 is a fibrous nonwoven fabric or porous plastic film, and liquid-impervious sheet 2 is a plastic film or waterproof. It is possible to use treated fiber non-woven fabric. However, it is necessary to make the frictional resistance of the skin contacting surface 5 against the wearer's skin larger than the frictional resistance of the non-skin contacting surface 6 against the sanitary shirt. Since it is preferable for further improving the stability, for example, when the skin contact surface 5 is made of a fiber non-woven fabric, the non-skin contact surface 6 is made of a plastic film having a smaller friction coefficient than the non-woven fabric. It is preferable.

[Effect of the device]

 According to the napkin of the present invention having the above configuration, since the adhesive on the fastening means is supported by the flexible elastic member, the napkin is well conformed to the uneven curved surface of the local skin and adheres stably. Since the napkin is securely held so that it comes into contact with a predetermined position, it is possible to prevent side leakage of menstrual blood as much as possible.

Further, even if the adhesive on the fastening means is peeled off from the skin for some reason, as long as the fastening means is in contact with the skin, the fastening means protruding from the skin contact surface may cause menstrual blood loss. Since it functions as a barrier against lateral outflow, it is possible to prevent menstrual blood from leaking sideways as much as possible.
