Detailed Description

The following detailed description will be provided for the embodiments of the present invention with reference to specific embodiments, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented.

Example one

Referring to fig. 1 and 2, a sanitary napkin with a central enclosure comprises a sanitary napkin body, wherein the sanitary napkin body comprises a surface layer 1, an absorption core layer 2 and a liquid-tight bottom layer 3, which are stacked, a flow guide layer 4 is arranged between the surface layer 1 and the absorption core layer 2, a downward-permeating hole 11 with a square structure is formed in the surface layer 1, and four sides of the downward-permeating hole 11 are curled to form an enclosure curled edge 12 with a cylindrical hollow structure for preventing front and back leakage and side leakage; specifically, the lower penetration hole 11 is one and is located at the center of the sanitary napkin body, it should be understood that the center of the sanitary napkin body is the place where the body fluid of the user is discharged and initially contacts with the sanitary napkin body, and is not limited to the center, but is a range capable of receiving the body fluid in a sufficient amount;

in the embodiment, the surface layer 1 is formed by mixing and warp knitting spandex and terylene, and the specification of the specifically adopted material is a line body with the denier of 20-100D; the surface layer 1 material has the characteristic that the edge is curled after being stressed, and the surface is flat when the surface layer is not stressed;

specifically, the containment beads 12 are divided into side beads 121 which are in the same direction as the length direction of the sanitary napkin body, and front and rear beads 122 which are in the same direction as the width direction of the sanitary napkin body, the side beads 121 are in a structure in which the edges of the infiltration holes 11 are curled upward, and the front and rear beads 122 are in a structure in which the edges of the infiltration holes 11 are curled downward; aiming at the different curling formed by the materials of the surface layer 1 under stress, due to the characteristics of the materials, the symmetrical two sides of the infiltration holes 11 with the square hole structure can form structures with different curling directions (rolling up or rolling down), the rolling up position is intentionally arranged on the side part of the sanitary towel body in the embodiment, the side leakage phenomenon is more easily caused on the traditional sanitary towel, and the rolling up structure is not blocked by the flow guide layer 4 and the absorption core layer 2 at the lower end, so that the height higher than that of the rolling down structure can be formed, and better blocking can be formed;

in this embodiment, the lower seepage hole 11 is disposed on the longitudinal symmetry center line of the flow guide layer 4. Thus, the function of the flow guide layer 4 can be combined to lead the body fluid to be uniformly guided and dispersed;

the technical scheme adopts a structure with lower seepage holes 11, body fluid at the positions of the lower seepage holes 11 directly falls onto the flow guide layer 4 for flow guide and dispersion, the process that the body fluid continuously penetrates downwards through the surface layer 1 is reduced, the infiltration rate is further improved, meanwhile, the four-side structure of the lower seepage holes 11 is designed, a protective edge curl 12 structure for preventing side leakage and front and back leakage is formed, the height of the protective edge curl 12 structure is certain, the body fluid falling into the positions of the lower seepage holes 11 can be effectively blocked, and the protective edge curl 12 structure is a hollow structure and is integrated with the surface layer 1, so that friction cannot be generated on a human body, and good comfort is ensured; surface course 1 adopts the mixed warp of warp knitting and forming of spandex and dacron two to play the fabric, through the material of improvement surface course 1, the use has elastic warp to play the fabric surface, utilize its surface fabric characteristic, down behind the both sides atress of infiltration hole 11, form the enclosure turn-up 12 structure that is located the hollow structure of infiltration hole 11 four sides down promptly, the product surfacing of output, and only need stimulate surface course 1 during the use can form the convolution, be convenient for protect the shaping of turn-up 12, there is not redundant part, do benefit to daily use.

It should be understood that other necessary components of the sanitary napkin body are not stated in the present technical solution; the material of the surface layer 1 is directly available in the market.

Example two

Referring to fig. 3 again, compared with the first embodiment, the two lower infiltration holes 11 are respectively located at the front and rear ends of the sanitary napkin body in the longitudinal direction. The front end and the rear end are positions close to the longitudinal ends, but not the edges, and fall into the projection plane of the absorption core layer 2; the structure of two lower seeping holes 11 forms two leakage-proof structures at the front and back of the sanitary towel body, which is more suitable for the conditions of large body fluid volume and large-size sanitary towel.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
