Description

Underpants type paper diaper

Technical Field

The utility model relates to the field of sanitary articles, in particular to an underpants type paper diaper.

Background

The difference between the pants-type diaper and the adhesive diaper is that the pants-type diaper is shaped like a small underpants, is worn in a manner similar to a small underpants, and is worn by pulling a shank after the shank is inserted into a leg opening. The underpants type paper diaper adopts a design of a 360-degree elastic waistline and is used for fitting the buttocks of a baby to enable the baby to be more close to the skin; in the prior art, the applicant of the present application has been granted a chinese utility model patent with a publication number of "CN 208591211U", which is an invention and creation name of a pair of pull-ups, including an absorber and an outer cover disposed outside the absorber, the outer cover is provided with a plurality of waistline elastic members extending in a width direction along an edge of a waist opening; the outer cover mainly comprises a front side surrounding part 11 and a back side surrounding part 12, and a side sealing structure is adopted to connect and fix two side edges of the front side surrounding part and two side edges of the back side surrounding part in a hot pressing manner during processing, so that the underwear-type paper diaper is formed. When the paper diaper is disassembled, the hot-pressed connecting part at the waist position at the front end and the rear end of the underpants type paper diaper can be torn off.

In addition, a leg rubber band 17 is arranged on the leg opening 16 of the underpants type paper diaper; after wearing, the leg rubber band can make the leg opening of the pants-type paper diaper fit with the thigh of the baby. In the traditional scheme, the preceding trousers body of pants type panty-shape diapers still can arrange many horizontal rubber bands 20 that transversely set up in the below region of side hot pressing joining region 19, the tip of shank rubber band is crisscross with the tip of horizontal rubber band, the crotch portion region that shank open-ended shank rubber band can laminate the thigh root when here horizontal rubber band is main for making the dress, but setting up of horizontal rubber band is comparatively troublesome, not only need arrange horizontal rubber band, and because horizontal rubber band passes the absorber, so need cut off it. In addition, when the baby carrier is used, the transverse rubber bands stretch the leg rubber bands, and obvious rib feeling can be generated on the corresponding legs of the baby.

Disclosure of Invention

In order to solve the problems, the utility model aims to provide the underpants type paper diaper, the transverse rubber band arranged below the inside of the hot-pressing connecting area is eliminated, the processes of arranging the transverse rubber band and cutting the transverse rubber band are omitted, and the production efficiency is improved; and the leg rubber bands are not stretched by the transverse rubber bands, so that the elastic force of the leg rubber bands can be uniform, and obvious rib feeling can not be generated locally.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a pants-type paper diaper comprises a pants body and an absorber arranged in the pants body; leg openings are arranged on two sides of the lower end of the trousers body; the trousers body comprises a non-water-permeable bottom layer, a front side wall part and a rear side wall part are respectively arranged at the front end and the rear end of the non-water-permeable bottom layer, two side edges of the front side wall part and two side edges of the rear side wall part are fixedly connected through a hot-pressing connecting area to form an elastic side wall for fitting the waist and the hip, and a waist opening is formed between the elastic side walls; the method is characterized in that: elastic non-woven fabrics and/or a plurality of elastic rubber bands are transversely arranged only in the front side wall part and the rear side wall part of the non-water-permeable bottom layer, and the end parts of the elastic non-woven fabrics and/or the elastic rubber bands in the front side wall part and the rear side wall part are fixed in the hot-pressing connection area; a plurality of leg rubbers are arranged on the non-water-permeable bottom layer at the edge of the leg opening, and the end parts of the leg rubbers are fixed in the hot-pressing connection area.

Furthermore, the hip elastic rubber band 104 is not arranged on the absorber 2, and the hip elastic rubber bands 104 are arranged at the two ends of the absorber 2, so that the absorber 2 can be stretched and unfolded, and the absorber 2 is prevented from being folded to influence the use effect.

Leg openings 16 are arranged on two sides of the lower end of the trousers body 1, a plurality of leg rubbers 17 are arranged on the non-water-permeable bottom layer 10 at the edges of the leg openings 16, and the end parts of the leg rubbers 17 are fixed in a hot-pressing connection area 19.

Above-mentioned technical scheme relates to a pants type panty-shape diapers, sets up shank opening 16 and waist opening 15 on this pants type panty-shape diapers pants body 1's the trousers body 1, stretches into baby's shank opening 16 during the use, will draw the trousers to lift up and make waist opening 15 cover at baby's waist buttock, elasticity side wall makes draw the trousers upper end laminating baby's health to accomplish and dress.

On the basis, the non-water-permeable bottom layer 10 is only provided with elastic non-woven fabrics and/or a plurality of elastic rubber bands in the front side wall part 11 and the back side wall part 12 in the transverse direction, the end parts of the elastic non-woven fabrics and/or the plurality of elastic rubber bands in the front side wall part 11 and the back side wall part 12 are fixed in the hot-pressing connecting area 19, namely the elastic non-woven fabrics and/or the plurality of elastic rubber bands are all used for enabling the elastic side walls to be attached to the waist and the hip. According to the scheme, the transverse rubber band arranged below the inner side of the hot-pressing connecting area 19 is eliminated, the processes of arranging the transverse rubber band and cutting off the transverse rubber band are omitted, and the production efficiency is improved. And the leg rubber bands are not stretched by the transverse rubber bands, so that the elastic force of the leg rubber bands can be uniform, and obvious rib feeling can not be generated locally.

In a further scheme, two U-shaped leg rubbers 17 are arranged on two sides in the non-water-permeable bottom layer 10 of the pants body 1, the U-shaped openings of the two leg rubbers 17 face the front side wrapping part 11 and the back side wrapping part 12 respectively, and the U-shaped end parts of the leg rubbers 17 are arranged in the hot-pressing connecting areas 19 which are fixed on two sides of the front side wrapping part 11 or the back side wrapping part 12 respectively. The leg rubber 17 is cut at a position passing through the absorbent body 2. As described above, the leg rubber 17 is for attaching the leg opening 16 of the pants body 1 to the leg of the baby, and it does not produce the above-mentioned effect when it passes through the absorbent body 2, and it also gathers the absorbent body 2 to affect the absorption effect. This solution therefore cuts off the leg rubber 17 at the point where it passes through the absorbent body 2, and only the leg rubber 17 including the edge of the leg opening 16 works.

In the above-described embodiment, the leg rubber 17 and the hip elastic string 104 passing through the absorbent body 2 are cut in multiple stages so as not to affect the expansion of the absorbent body 2 when worn.
