Description
Technical field
The present invention relates to a kind of sanitary towel, relate in particular to a kind of anti-back and leak sanitary towel.
Background technology
Sanitary towel as menstrual period absorbing articles obtain significant progress the seventies from eighties of last century, the nineties, the quality owing to the improvement sanitary towel of raw and auxiliary material was further improved, no matter be that the absorbtivity or the skin-friendly of lining can all obtain very big improvement, since menstrual period the women when night in bed, often flow backwards backward through liquid along gluteal fold, surpass the effective absorption region of sanitary towel, lead the menses sheet medicated clothing etc. of making dirty, there is the people to prevent the generation of this rough sledding by the length that strengthens sanitary towel for this reason, the very long very big sanitary towel of fantail that is a kind of sanitary towel of specialized designs rear portion wraps buttocks, even menses flow behind the gluteal fold of back like this, also can be absorbed by sanitary towel, the rough sledding of doing like this is, requires the non-constant width of fantail of sanitary towel back, and the spoke face of corresponding raw material requires wide, absorber will cover the length of whole fantail, and in fact as long as one section very short absorber can satisfy the requirement of absorbtivity, and the long like this sanitary towel of design causes absorbent properties to be wasted widely.Also the someone designs a kind of composite sanitary napkin; he uses built-in tapon and common protective wing type sanitary napkin jointly; purpose is to absorb earlier before menses flow out; the outside adds a slice sanitary towel again and is protected; as many as two sanitary towels say from the angle of cost to remain uneconomic.
Summary of the invention
This utility model provides a kind of menses that can stop to leak sanitary towel along the mobile backward anti-back of gluteal fold.
The technical solution adopted in the utility model is such: sanitary towel is leaked in a kind of anti-back, comprise permeable top layer, opaque liquid bottom and be wrapped between the two absorbent cores, comprise a projection between described permeable top layer and the absorbent cores, the longitudinal length of described projection is less than the longitudinal length of absorbent cores, the width of described projection is less than 1/2nd of the absorbent cores width, and the height of projection is greater than 5mm.
Sanitary towel is leaked in preferred above-mentioned anti-back, and described protruding longitudinal length is less than 1/3rd of absorbent cores longitudinal length.
Sanitary towel is leaked in preferred above-mentioned anti-back, and described convex cross section is " e " font.
Sanitary towel is leaked in preferred above-mentioned anti-back, and described convex cross section is " Z " font.
Sanitary towel is leaked in preferred above-mentioned anti-back, and described projection forms by bulk non-woven fabrics is folding.
Sanitary towel is leaked in preferred above-mentioned anti-back, and described projection is made of paper oar fiber.
Sanitary towel is leaked in preferred above-mentioned anti-back, and described projection is made of absorbent cotton.
This utility model has added a projection between absorbent cores and permeable top layer, this projection can cooperate with women's gluteal fold, and the menses that the back is leaked in time absorb, prevent to make dirty sheet, medicated clothing etc., and this SANITARY NAPKIN CONSTRUCTION is simple, practical.
