Description

A kind of safety pants with thermal paste

technical field

The invention relates to the technical field of disposable sanitary products, in particular to a safety trousers with a temperature-sensitive sticker.

Background technique

Relief pants are a kind of pants-type sanitary napkin. From the perspective of its structure, the sanitary napkin is firmly fixed on the disposable underwear, and there is no worry about the deviation of the sanitary napkin. Relief pants have a large absorption capacity, which can effectively prevent the leakage of sanitary napkins, and are very popular among female compatriots.

The inventor pointed out that many female compatriots are susceptible to cold and aggravate dysmenorrhea during menstruation. When menstruation is painful, the lower abdomen where the female uterus is located can be heated to avoid cold and relieve dysmenorrhea. Based on the above phenomenon, the inventors have developed a safety pant with a thermal patch, which can slowly self-heat when worn, effectively relieving women's dysmenorrhea.

In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a kind of safety pants with a thermal paste, comprising a safety pants body, and the safety pants body includes an elastic front waistline, a crotch and an elastic back waistline, and the elastic The front waistline and the elastic back waistline are bonded to form a relief trousers body with a waist opening and two leg openings; the crotch of the relief pants body is provided with a sanitary napkin, and the relief pants body corresponds to the sanitary napkin The coverage area is the absorption area, and the area other than the absorption area on the body of the safety pants is the non-absorbing area;

The safety pant body includes an outer non-woven layer and an inner non-woven layer, the outer non-woven surface is located in the non-absorbing area and is coated with a plurality of thermally conductive ink strips, and each of the thermally conductive ink strips is located on the outer side. between the non-woven layer and the inner non-woven layer;

The safety pants body is provided with a warm-sensitive sticker at the position of the female uterus, and the corresponding warm-sensitive sticker coverage area on the safety pants body is a warm-sensitive area;

The temperature-sensitive sticker includes a first airtight film layer, a dust-free paper layer and a second airtight film layer; the first airtight film layer is adhered to the outer non-woven fabric layer, and each strip of the thermally conductive ink is One end is located in the temperature-sensitive area; the peripheral edge of the second air-impermeable film layer is bonded to the first air-impermeable film layer, and a sandwich is formed between the first air-impermeable film layer and the second air-impermeable film layer , the dust-free paper layer is arranged in the interlayer, and the self-heating material is evenly distributed on the side of the dust-free paper layer close to the first air-impermeable film layer;

The second air-impermeable film layer is provided with a plurality of air-permeable regions, and each of the air-permeable regions is provided with a plurality of air-permeable holes; The third air-impermeable film layer completely covers each air-permeable hole in the corresponding air-permeable area, so that a closed space is formed in the interlayer.

Further, between the outer non-woven layer and the inner non-woven layer, leg circumference elastics are provided at the opening positions of the two leg circumferences.

Further, the first air-impermeable film layer is made of tin foil.

Further, the second air-impermeable film layer and each of the third air-impermeable film layers are made of plastic films.

Further, the third air-impermeable film layer includes an adhesive portion and an easy-tear portion, the adhesive portion of the third air-impermeable film layer is adhered to the air-permeable region, and the easy-tear portion of the third air-impermeable film layer. No adhesion to the second air impermeable film layer.

By adopting the aforementioned technical solutions, the beneficial effects of the present invention are: when the safety pants with temperature-sensitive stickers are used, the third airtight film layer is torn open, and when the third airtight film layer is torn, the air enters the interlayer, so that the air enters the interlayer. The self-heating material reacts with oxygen to generate heat. On the one hand, the heat is conducted to the first airtight film layer to warm the female uterus and relieve dysmenorrhea; Other locations also feel warm. The more the third airtight film layer is torn, the more air enters the interlayer, and the more heat is emitted by the self-heating material. Users can judge the number of the third airtight film layer torn according to their own feelings.

Further, the third air-impermeable film layer includes an adhesive portion and an easy-tear portion, and the user can easily tear the third air-impermeable film through the easy-tear portion.

Detailed ways

The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

Referring to FIGS. 1-5 , the present embodiment provides a safety pant with a thermal paste, including a safety pant body 1 , and the safety pant body 1 includes an elastic front waistline 100 , an elastic back waistline 101 and a crotch portion 102 , The elastic front waistline 100 and the elastic back waistline 101 are bonded to form a safety pant body 1 having a waist opening 104 and two leg openings 105 . The structure of the above-mentioned safety pant body 1 is the existing safety pant body structure. A sanitary napkin 2 is provided on the crotch portion 102 of the body 1 of the safety pant.

As shown in FIG. 3 , the area covered by the corresponding sanitary napkin 2 on the safety pant body 1 is taken as the absorbing area 200 , and the area other than the absorbing area on the safety pants body is the non-absorbing area.

The safety pant body 1 includes an outer non-woven fabric layer 10 and an inner non-woven fabric layer 20 . Between the outer non-woven fabric layer 10 and the inner non-woven fabric layer 20 , leg circumference elastics 3 are provided at the positions of the two leg circumference openings 105 . The surface of the outer non-woven fabric 10 is located in the non-absorbing area and is coated with a plurality of thermally conductive ink stripes 5 at intervals. In this specific embodiment, the number of thermally conductive ink stripes 5 is set to four, and each of the thermally conductive ink stripes 5 is located on the outer side. between the non-woven fabric layer 10 and the inner non-woven fabric layer 20 .
