Description

Sanitary cotton

The invention relates to a sanitary napkin, in particular to a sanitary napkin which is leakproof.

Sanitary cotton is a hygienic product invented to help women have a better quality of life during menstruation. After years of development, the design of sanitary napkins has become more diverse, which can enhance the comfort of different levels. Referring to Fig. 1, a general sanitary napkin 1 includes an absorbent pad 11 for receiving menstrual blood, and a flap 12 disposed below the absorbent pad 11 and extending toward the left and right sides for contacting the human body. Although the absorbent pad 11 can receive and absorb menstrual blood, when the instantaneous flow rate of menstrual blood is large and the absorbent pad 11 is too late to be absorbed, the menstrual blood will flow along the absorbent pad 11 which is temporarily unable to absorb the liquid, resulting in leakage of menstrual blood. This causes inconvenience and discomfort to the user. For example, when the user is lying down, the tilted posture tends to cause the menstrual blood to flow backwards intensively, so that the absorbent pad 11 does not have time to absorb and then leaks. Further, since the absorbent pad 11 is in contact with the genitals of the user over the entire surface, the air permeability is poor and it is likely to cause discomfort to the user.

Accordingly, it is an object of the present invention to provide a sanitary napkin that is multi-leakproof and breathable.

Thus, the sanitary napkin of the present invention comprises a cotton pad and a retaining pad disposed on the cotton pad. The barrier pad surrounds a plurality of isolation grooves arranged in the front-rear direction and communicating with the cotton pad.

The effect of the invention is that the menstrual blood is absorbed by the cotton pad through the isolation grooves, and the menstrual blood that is not absorbed can be blocked by the barrier pad and located in the isolation grooves, thereby avoiding the menstrual blood flowing around. leak. Even if the user is inclined, the menstrual blood will be protruded on the cotton pad to block the barrier pad with a certain thickness, effectively avoiding the situation of rear leakage. In addition, the isolation grooves make the barrier pad not touch the user on the whole surface, which is convenient for ventilation and can improve the comfort of use, that is, the ventilation design with voids formed by each isolation groove makes contact with human skin. The area is smaller and it is more breathable and dry.

The barrier pad 4 surrounds a plurality of isolation grooves 40 spaced apart in the front-rear direction and communicating with the cotton pad 3. In use, the menstrual blood flows into the isolation grooves 40 and is absorbed by the cotton pad 3. When the flow rate of the menstrual blood is too large to allow the cotton pad 3 to be absorbed at a time, the isolation grooves 40 can be used to accommodate menstrual blood. The menstrual blood does not flow along the cotton pad 3 and leaks. When the user lies down and tilts the sanitary napkin 2, the menstrual blood is stopped by the barrier pad 4 having a thickness and continues to be accommodated in the isolation. The groove 40 is inside so that the back leak can be avoided. In addition, through the design of the isolation grooves 40, the barrier pad 4 is not completely touched to the user, thereby improving the breathability and comfort, that is, having a gap formed by each of the isolation grooves 40.
