Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, an unfolded sanitary napkin comprises a cotton surface layer 10, a functional core 13 disposed in the middle of the cotton surface layer 10, and a sealing film 14 disposed on the outer surface of the cotton surface layer 10 and the outer surface of a bottom film 17.

Wherein, the lower surface on cotton top layer 10 is provided with sealed cloth 11, and the lower surface of sealed cloth 11 is provided with non-woven fabrics 16 and basement membrane 17, is provided with between sealed cloth 11 and the non-woven fabrics 16 and absorbs core 15, and the upper surface on cotton top layer 10 still is provided with water blocking strip 12, provides inboard sealed effect through sealed cloth 11, and water blocking strip 12 then is used for supplementary spacer with inboard sealed cloth 11.

The water-blocking strips 12 are in an end-to-end connection regular arc-shaped structure, the water-blocking strips 12 are uniformly distributed on the outer side of the functional core body 13, and menstrual blood seeping from the absorption core body 15 due to extrusion can be absorbed at each position;

wherein, a plurality of liquid holes 122 that run through have all been seted up on the surface of cotton top layer 10 and sealing cloth strip 11, liquid hole 122 evenly sets up, the inboard arcuation structure of water blocking strip 12 separates there is liquid chamber 121, liquid chamber 121 and liquid hole 122 intercommunication, menstrual blood is generally absorbed the storage in the inside of absorbing core 15, absorb core 15 when receiving excessive extrusion, its inside menstrual blood can be extrudeed and oozed, because the extrusion can lead to absorbing core 15 inside to lack the space and give the menstrual blood detention, lead to the menstrual blood can ooze, but because the liquid hole 122 that sets up provides the slotted hole that can circulate, make the menstrual blood that can ooze can follow the inside that liquid hole 122 got into liquid chamber 121, provide buffer space, temporary storage menstrual blood, avoid the problem of menstrual blood oozing to take place.

The bottom film 17 is arranged on the lower surface of the non-woven fabric 16, the outer side of the edge of the bottom film 17 is tightly attached to the cotton surface layer 10, the inner side of the edge of the bottom film 17 is bonded with the non-woven fabric 16, the non-woven fabric 16 provides a sealing effect, the bottom film 17 assists in sealing, the outer side of the bottom film 17 and the outer portion of the cotton surface layer 10 are integrally wrapped with the upper sealing envelope 14, and the structure is encapsulated;

wherein, the waterproof strip 12 is rubber materials, the junction between the surface of waterproof strip 12 and the cotton top layer 10 all is provided with the fluff pulp, the waterproof strip 12 that is the rubber materials of arcuation is when receiving the extrusion, not only can produce the deformation, reduce the discomfort that user's leg root received, and can guarantee that inside sap cavity 121 possesses certain space all the time, can guarantee that buffer structure exists all the time, in addition through the fluff pulp that sets up on the surface, can guarantee the comfort of user direct contact position skin.

The reason why the functional core 13 is in close contact with the absorbent core 15, the upper surface of the absorbent core 15 is in close contact with the liquid holes 122 at positions on both sides, the functional core 13 absorbs menstrual blood and permeates the menstrual blood into the absorbent core 15, and the absorbent core 15 is in close contact with the liquid holes 122 is to ensure that the menstrual blood can be pushed into the liquid chamber 121 from the liquid holes 122 when the absorbent core 15 is pushed.

The working principle is as follows: when using, aim at the vagina position with function core 13 and place, this moment water blocking strip 12 is located thigh root position, during daily use, absorb and transmit absorption core 15 with menstrual blood through function core 13, after absorbing too much menstrual blood, if receive the extrusion, can make the absorbed menstrual blood of absorption core 15 ooze, the inside of sap cavity 121 can be impressed with the extruded mode through sap hole 122 to the menstrual blood that oozes, provide the storage space of buffering, avoid at the extrusion in-process, because absorb core 15 inner space not enough, lead to the problem that the menstrual blood oozes, water blocking strip 12 adopts rubber materials in addition, its surface sets up the fluff pulp, can guarantee certain travelling comfort, water blocking strip 12 sets up to the arcuation structure and surrounds function core 13, can guarantee immediately at water blocking strip 12 is extruded, still can remain the space and can carry out temporary storage menstrual blood.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
