Description

Disposable infant shorts type underpants

Technical Field

The present utility model relates to disposable absorbent sanitary articles and, more particularly, to disposable infant pants.

Background

In modern society, infant's daily nursing is to be kept away from pull-up pants and ordinary panty-shape diapers, and the difference between them lies in the pull-up pants shape just like little pants, adopts 360 degrees elasticity waistline designs. On one hand, the design is convenient for putting on and taking off, and the baby can be conveniently replaced no matter lying down or standing up; on the other hand, the utility model is more comfortable. However, most of the current market is an integrated pull-up pants, the waist opening and leg opening are often very tight, and the waist opening and leg opening are too thick after absorbing urine, so that a baby feels uncomfortable, and after the baby is gradually conscious, the baby can resist the emotion of wearing the pull-up pants.

The traditional paper diaper or pull-up diaper adjusts the water absorption capacity of the training pants by improving the water absorption polymer resin, but the too much water absorption capacity can lead to the thick crotch bottom, is uncomfortable when being worn, and is easy to generate stuffiness to cause skin erythema.

In the prior art, CN 206026549U discloses a functional infant training pant, which comprises a training pant main body, wherein a waterproof layer and a water-absorbing layer are sequentially arranged at the crotch of the training pant main body, the waterproof layer is made of a TPU film, and the water-absorbing layer is made of wood fiber; the training pants main body comprises a front piece, a crotch part and a back piece, wherein two sides of the front piece are respectively connected with two sides of the back piece to form an annular structure, and the front and back sides of the crotch part are respectively connected with the front piece and the back piece. According to the utility model, the TPU material waterproof film layer and the water-absorbing layer of the wood fiber material with the water-absorbing but water-locking function are used, so that the infant can release urine, the urine does not wet the outer trousers, and the infant can feel abnormal uncomfortable feeling caused by the urine, so that the behavior habit of the infant for controlling the urine can be trained. However, the air permeability of the TPU material waterproof film layer is too poor, so that discomfort caused by the TPU material waterproof film layer is too strong, the infant is easy to generate conflict emotion, and the skin of the infant is easy to form erythema due to sultriness generated by the TPU.

CN 209301502U discloses a pants-type pull-up pants, comprising a pair of paper pull-up pants, wherein the pants-type pull-up pants are in the form of external pants, the crotch part of the paper pull-up pants is provided with an absorbent core, and the absorbent core comprises a main absorbent core, a hydrophobic non-woven fabric and an auxiliary absorbent core; the main absorption core body is divided into an abdomen area, a bottom baffle area and a rear waist area according to the corresponding human body part, the hydrophobic non-woven fabric is adhered to the upper surface of the rear waist area of the main absorption core body, the auxiliary absorption core body is adhered to the upper surface of the hydrophobic non-woven fabric, a plurality of flow blocking grooves are formed in the bottom baffle area at intervals at the boundary line between the rear waist area and the bottom baffle area, and each flow blocking groove is formed along the width direction of the main absorption core body. According to the utility model, on one hand, the rear waist area of the shorts type pull-up pants is provided with the hydrophobic non-woven fabric, so that urine is prevented from being absorbed by the main absorption core body to the auxiliary absorption core body to cause discomfort of babies; on the other hand, the baffle slot is arranged on the bottom baffle area, so that urine can be effectively prevented from directly flowing onto the auxiliary absorption core body. However, the secondary absorbent core directly contacts the delicate skin of the infant, which is disadvantageous to the skin of the infant and is not suitable for long-term use.

CN 213307456U discloses a waterproof leak-proof underpants with moisture vapor, which comprises an underpants body, wherein the middle lower side of the underpants body is fixedly arranged as a crotch part; the middle part of the inner surface of the underpants body is fixedly connected with grey cloth, the basic structure of the underpants body is provided with a cotton cloth layer, the outer surface of the cotton cloth layer is fixedly connected with a hemp fiber layer, and the inner surface of the cotton cloth layer is fixedly connected with a waterproof coating; the two sides of the lower part of the underpants body are respectively provided with a trouser opening, and the trouser openings are correspondingly arranged at the left side and the right side of the crotch part. In the utility model, the outer surface of the underpants is provided with the hemp fiber layer, the inner surface of the underpants is provided with the waterproof coating, the waterproof performance of the waterproof coating is insufficient, and the ventilation performance of the hemp fiber layer and the grey cloth is insufficient, so that the genitals are easy to be infected.
