The utility model will now be further described with reference to the drawings and detailed description.

Referring to fig. 1 to 6, a mini sanitary towel according to the first embodiment includes, from top to bottom, a liquid permeable top layer 1, an absorbent layer 2, a liquid impermeable bottom layer 3, release paper 4 and a packaging paper 5, wherein the outer side of the liquid permeable top layer 1 is compounded with the liquid impermeable bottom layer 3, the bottom surface of the liquid impermeable bottom layer 3 is bonded with the release paper 4, the bottom surface of the release paper 4 is bonded with the packaging paper 5, a plurality of sets of liquid guiding grooves are provided on the surface of the absorbent layer 2, wherein one set of liquid guiding grooves includes an elliptical groove 1a and a first central groove 1b, the elliptical groove 1a is distributed in an annular array, and the first central groove 1b is located at the center of the annular array of the elliptical groove 1 a; preferably, the distance between the absorption layer 2 and the liquid-impermeable bottom layer 3 is 3-16 mm, and the mini-type sanitary towel has small volume and reduces the area after packaging.

The arrangement of the liquid guide grooves, wherein the oval grooves are distributed in an annular array, the first central groove is arranged at the center of the annular array, the shape of the first central groove is similar to that of a sunflower, the attractive appearance is good during use, and when the liquid passes through the oval grooves, the liquid can be quickly absorbed by the liquid to flow to the first central groove, so that the absorption performance of the absorption layer is enhanced.

When miniature sanitary towel is produced, input liquid impermeable bottom layer 3, at input liquid permeable top layer 1 and absorbed layer 2, compound liquid permeable top layer 1 through the compound roller, absorbed layer 2 and liquid impermeable bottom layer 3 are compound, accomplish again with the sizing of liquid impermeable bottom layer 3 bottom surface middle part, and paste from type paper 4 in the intermediate position, then glue from type paper 4 bottom surface, paste again wrapping paper 5, as shown in fig. 1, two crease lines a have on miniature sanitary towel, fold sanitary towel in two crease lines through folding device, then carry out the hot pressing fixed to the sanitary towel middle part that the fifty percent discount is good, form fixed part 5b, carry again after accomplishing, carry out the hot pressing complex with wrapping paper 5 horizontal both sides, both sides will form hot seal 5a, accomplish the hot pressing seal to sanitary towel, this is located liquid impermeable bottom layer 3 middle part from type paper 4, glue in the convenient production process, and this liquid impermeable bottom layer 3 middle part area is big, can glue the size big, can paste firmly with outside trousers body, reduce the volume after the miniature sanitary towel encapsulation of side wing, more convenient carry out.

The liquid guide grooves are provided with a plurality of longitudinal rows, and the adjacent longitudinal rows are staggered; when liquid flows downwards from the liquid impermeable and absorbing layer 2, part of the liquid flows into the liquid guide grooves, and the liquid which does not pass through the liquid guide grooves continues to flow downwards.

The middle part of the oval groove 1a is provided with a downwards concave arc groove 11a, a first transition curve 12a is arranged between one side of the arc groove 11a and the surface of the absorption layer 2, a second transition curve 13a is arranged at the other side of the arc groove 11a and close to the first central groove 1b, the height difference between the top end of the first transition curve 12a and the top end of the second transition curve 13a is 1-3 mm, the distance from the first central groove 1b to the surface of the absorption layer 2 is greater than the distance from the arc groove 11a to the surface of the absorption layer 2, and the top end of the first central groove 1b is in smooth transition with the second transition curve 13 a.

The arrangement of the arc grooves 11a is that the oval grooves 1a are high, liquid flows into the arc grooves 11a through the first transition curves 12a, the depth of the arc grooves 11a is large, part of liquid can be stored and absorbed, and as the oval grooves 1a are distributed in an annular array, the height difference between the top ends of the first transition curves 12a and the top ends of the second transition curves 13a is 1-3 mm, the surfaces of the liquid permeable surface layer 1 and the absorption layer 2 are positioned at the oval grooves 1a and are hemispherical concave, after the liquid in the arc grooves 11a is fully accumulated, the liquid is guided to flow into the first central groove 1b for absorption, so that the defect of a large amount of accumulated liquid at the middle part of the sanitary towel caused by overflow of the liquid after passing through the arc grooves 11a is avoided; because the distance from the first central groove 1b to the surface of the absorption layer 2 is greater than the distance from the arc-shaped groove 11a to the surface of the absorption layer 2, the depth of the first central groove 1b is deeper, and because the density of the first central groove 1b is lower, and the surfaces of the liquid-permeable surface layer 1 and the absorption layer 2 are fluffy, the first central groove 1b is less in fit with the skin of a human body, and discomfort cannot be caused in the use process.

Referring again to fig. 7, the second embodiment discloses a mini-type sanitary napkin, which is different from the first embodiment in that: the liquid guide groove on the absorption layer 2 is additionally provided with a second central groove 1c, and the second central groove can strengthen the liquid guide performance of the absorption layer; the specific position is that the second central groove 1c positioned at the top of the absorption layer 2 is distributed at the bottom of the liquid guide groove, and the second central groove 1c positioned at the bottom of the absorption layer 2 is distributed at the top of the liquid guide groove; the second central grooves at the top and the bottom can strengthen the flow guiding of the liquid flowing into the second central groove 1c at two sides, and further improve the liquid guiding performance; the second central groove 1c positioned in the middle of the absorption layer 2 is in an annular subsection, and the accumulated liquid in the middle is more, so that the accumulated liquid performance of the elliptical groove 1a can be increased, and the accumulated liquid in the middle is prevented from leaking from the lateral sides.
