Description

Sanitary napkin with flow-guide slot

This utility model relates to life dressing, particularly sanltary towel.

Existing sanitary towel is that it is covered with toilet paper up and down with the paper pulp short flannel absorbed layer of deciding, and is covered with the polyethylene antiseepage film below again, scribble pressure sensitive adhesive with non-weaving cloth cladding bottom surface then, be fixed on the underwear and use, it is compared with toilet paper, soft absorbent is good, and is easy to use.But because diffusion is not enough along its length, secretions focuses mostly on around vaginal orifice, and in addition absorbability is limited, and the thickness of general sanitary towel is bigger, about 10 millimeters, lacks comfort during use.In order to reduce the known technology of thickness China Patent No. CN86209705, the paper pulp short flannel surface of face is used in proposition in sanitary towel, spilt powdery water absorbing agent sodium polyacrylate, to improve absorbent properties, but outside decapacitation forms and congeals after latter's imbibition, also have a small amount of low polymer water-soluble, the capacity reverse osmosis has a negative impact to human body to the sanitary towel surface.

The purpose of this utility model is to provide a kind of new have high absorption efficiency, slimming, comfortable reliable sanitary towel.

The use face that is characterised in that in sanitary towel of the present utility model, rolling along its length has guiding gutter, is beneficial to the distribution of secretions elongatedness direction and is added with water absorbing agent below the paper pulp short flannel.Be extended with aileron in the napkin width both sides, sanitary towel's absorbability height of making.Thickness is little, and is comfortable reliable in the use.

This utility model SANITARY NAPKIN CONSTRUCTION such as Fig. 2; it uses the surface to be non-weaving cloth 1, and the second layer is a toilet paper 2, is respectively paper pulp short flannel 3 secondly; water absorbing agent 4; toilet paper 2, polyethylene antiseepage film 5, bottom non-weaving cloth 6; two-layer up and down non-weaving cloth and antiseepage film broad ways are extended with aileron 7; its limit is slow to make sanitary towel be fixed into sealed whole body through heat bonding, in the bottom and the aileron both sides all scribble pressure sensitive adhesive 8, and protect with release paper 10.Toilet paper wherein, paper pulp short flannel and water absorbing agent are formed absorbed layer.

The said guiding gutter 9 of this utility model, as Fig. 1 .2, shown in, its position is by the sanitary towel center, become X-shaped along distribution of lengths, its garden arc radius is the 100-150 millimeter, Center Length is the 120-160 millimeter, and Breadth Maximum is the 30-50 millimeter, and the upper width of groove is the 2-4 millimeter, lower width is the 1-2 millimeter, the degree of depth is the 60-80% of caliper, when secretions is absorbed around the vaginal orifice, can prolong sanitary towel's length seepage flow along guiding gutter, enlarge effective usable floor area of sanitary towel, improve absorbability.

The said water absorbing agent of this utility model, the copolymer that can be sodium acrylate and acrylate also can be acrylic acid and starch-grafted polymer, it can absorb artificial urine 30-60 doubly, form gelatin and water insoluble substantially, it is shaped as and granularly mixes with powdery, and the accounting example is 20-80% respectively, and is said granular, its particle diameter is the 0.01-1 millimeter, and said powdery fineness is at the 60-80 sieve aperture.Water absorbing agent is added in below the paper pulp short flannel, and its distribution density is 1-10 milligram/cm ², distribution area accounts for the 50-100% of absorbed layer area, and the water absorbing agent consumption accounts for absorbed layer weight 5-50%, because water absorbing agent has very high imbibition ability, thereby can reduce the thickness of sanitary towel.

The said paper pulp short flannel of this utility model is to be pulverized by wood pulp or cotton pulp that to form its ulking thickness be the 2-5 millimeter, and the caliper of making is the 2.5-6 millimeter.

The said aileron of this utility model such as Fig. 1 .2; shown in be by up and down two-layer non-weaving cloth and plastic leakage-proof film extend into two arc shaped wings along the napkin width direction; its Breadth Maximum is the 155-165 millimeter; greatest length 100-110 millimeter; a slice PSA film is respectively arranged at the bottom of each wing tip; and isolate with separate paper; tear separate paper during use; with two ailerons sanitary towel is encased the underwear edge; be bonded at its outer surface, and along the pressure sensitive adhesive of sanitary towel's distribution of lengths, in tow sides double fixed sanitary towel in the bottom surface; it neither can be moved also not can torsional deformation, and underwear is had protective effect.

This utility model example 1, as Fig. 1 .2, be depicted as the plain edition sanitary towel that uses menstrual period, its total length is 225 millimeters, 200 millimeters of absorbed layer length, width is 70 millimeters, and the aileron width is 155 millimeters, and caliper is 5 millimeters, guiding gutter garden arc radius on the use face is 100 millimeters, Center Length is 120 millimeters, and Breadth Maximum is 35 millimeters, is added in the water absorbing agent of absorbed layer bottom.

This utility model example 2 as shown in Figure 3,280 millimeters of its length overalls of big liquid absorption type of using for night or puerpera, absorbed layer length is 260 millimeters, the absorbed layer width is 80 millimeters, 160 millimeters of aileron Breadth Maximums, 150 millimeters of guiding gutter arc radius, 145 millimeters of Center Length, 40 millimeters of Breadth Maximums, two arc joinings 30 millimeters apart from sanitary towel length center.
