Description

Technical Field

[0001] The utility model relates to the field of disposable sanitary products, in particular to a new type of diaper. Background Art

[0002] The structure of diapers is generally as follows: from top to bottom, it includes a liquid-permeable surface layer, an absorbent core layer, and a liquid-impermeable bottom layer, the absorbent core layer is a block structure formed by combining a fluffy non-woven fabric with a polymer absorbent resin or a mixture of wood pulp fibers and a polymer absorbent resin and wrapped by a non-woven fabric, which is used to absorb and retain human excrement. The liquid-permeable surface layer is composed of a hydrophilic non-woven fabric and a hydrophobic non-woven fabric fixed on both sides of the hydrophilic non-woven fabric. The hydrophilic non-woven fabric adheres to the upper surface of the absorbent core layer and is bent downward and coated on both sides of the absorbent core layer, and is attached to the absorbent core layer. The layer is adhered to the liquid-impermeable base layer, and is used to provide a comfortable and dry feeling when in contact with the body, while allowing liquid to pass freely into the absorbent core layer below. The liquid-impermeable base layer is composed of a breathable, water-impermeable film and a hydrophobic non-woven fabric composite, and is used to keep the absorbed liquid in the absorbent core layer, thereby preventing the absorbed liquid from soiling the wearer's pants, and an elastic band is arranged in the rear waist area, so that the rear waist area has lateral elastic stretchability, and ear stickers are arranged on both lateral sides of the rear waist area for fitting with the front waist area to achieve the wearing of the diaper.

[0003] However, when in use, the ear stickers are attached to the side waist of the diaper. Although they have an elastic adjustment function, the elastic area on the entire elastic waist is unevenly distributed, making the elastic force uneven. The ear stickers are mostly attached to the lateral sides of the front waist area, and the ear stickers are relatively hard and have poor fit, which can easily form lateral pulling force and vertical downward pulling force. The pulling force is aggravated during the user's activities, which can easily cause the ear stickers to separate from the front waist area, thereby causing the diaper to fall off.

[0004] Therefore, in view of the above problems, the present invention provides a novel diaper, which mainly solves the problem of poor fit of the ear patches in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A novel diaper, comprising a diaper body and ear stickers, wherein the longitudinal direction extending along the length direction of the diaper body is defined as the longitudinal direction, and the transverse direction extending along the width direction thereof is defined as the transverse direction, wherein the diaper body comprises a front waist region, a rear waist region, and a crotch region connecting the front waist region and the rear waist region, wherein the ear stickers comprise an ear sticker body arranged on both transverse sides of the rear waist region and an ear sticker auxiliary sheet arranged on both transverse sides of the front waist region, wherein the ear sticker body comprises a connecting sheet and an adhesive sheet, wherein the adhesive sheet is compounded on the outer end of the connecting sheet, wherein the surface of the adhesive sheet comprises an adhesive area, wherein the connecting sheet comprises an adhesive sheet distributed sequentially from the inner end to the outer end A connecting area, an extension area and a fitting area are set, the ratio of the lateral length dimension of the extension area to the lateral length dimension of the fitting area is 1:1.2-6, the longitudinal width dimension of the connecting area is equal to the longitudinal width dimension of the extension area, the longitudinal width dimension of the fitting area is smaller than the longitudinal width dimension of the extension area, the fitting area has a first inclined edge and a second inclined edge, the slope of the first inclined edge is greater than the slope of the second inclined edge, and the diaper body includes a liquid-permeable surface layer, an absorbent core layer, a liquid-impermeable bottom layer and an elastic sheet arranged at the back waist area, which are stacked in sequence from top to bottom.

[0007] Furthermore, the liquid-permeable surface layer includes a hydrophilic nonwoven fabric, a hydrophobic nonwoven fabric disposed on both lateral sides of the hydrophilic nonwoven fabric and covering both lateral sides of the absorbent core layer, and an elastic rubber disposed on one side of the hydrophobic nonwoven fabric facing each other.

[0008] Furthermore, a guide groove having a prismatic structure is concavely provided on the upper surface of the absorbent core layer.

[0009] Furthermore, recessed grooves are provided in the longitudinal middle portions of the two lateral sides of the absorbent core layer.

[0010] Furthermore, the connecting sheet comprises an outer layer body and an inner layer body which are laminated and composited, and the inner end of the adhesive sheet is sandwiched between the outer layer body and the inner layer body.

[0011] Furthermore, the transverse length dimension of the outer layer is greater than the transverse length dimension of the inner layer.
