Description

Pull-up diaper capable of avoiding urine leakage

Technical Field

The utility model relates to the technical field of articles for daily use for babies, in particular to pull-up pants capable of avoiding urine leakage.

Background

The pull-up pants adopt a design of a 360-degree elastic waistline, are comprehensively and dynamically attached to the belly of a baby, so that the baby cannot be caught even if the belly is round, and urine cannot leak even if the belly is flat before eating. The full line of 2016 baby 'S suitable draw trousers upgrade of group has adopted S waist line, and the design of more laminating baby' S ergonomic effectively reduces baby 'S thigh and the red seal that the waist produced because of the friction, more has the design of the narrow crotch of U type, and the baby' S both legs of more laminating climb and run and jump all easily freely. Along with the improvement of living standard of people, the pull-up diaper for transition from the paper diaper to the common underpants appears, the pull-up diaper is of an integral structure like underpants, and children cannot easily wet the outside without pulling down the pull-up diaper.

At present, the pull-up diaper on the market is various in varieties, but most of the pull-up diapers usually have the condition of liquid leakage due to the design and production process, so that the comfort level of the baby is influenced, and the movement of the baby is inconvenient. In order to solve the problems, some innovative proposals are also proposed in part of the domestic patent technology, such as: chinese patent application No. CN201920668871.9 discloses a leak-proof pull-up diaper with a multi-layer core, which adopts a multi-layer structure to prevent urine leakage and has certain technical effects; the chinese patent application No. CN202020441766.4 also provides a leak-proof pull-up diaper, which has a certain effect on the leak-proof of the pull-up diaper by the structural arrangement of the water-absorbing particles and the elastic fiber layer.

However, according to the technical scheme, the problem that the Lala pants expand after absorbing urine is ignored, so that the crotch and the hip of a baby are easy to be airtight and hot, disadvantages such as 'red hip' occur, and the baby is uncomfortable.

Therefore, based on the aforesaid, this application provides a can avoid leaking the pull-up diaper of urine, through structure and the material improvement to traditional pull-up diaper, when effectively solving the urine problem of leaking, avoids the air impermeability that the pull-up diaper bloated and arouses as far as possible, effectively solves not enough and the defect that prior art exists.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide the following advantages: to the above-mentioned problem that exists at present, provide a can avoid leaking the pull-up diaper of urine, through structure and the material improvement to traditional pull-up diaper, when effectively solving the urine problem, avoid the air impermeability that the pull-up diaper bloated and arouse as far as possible, effectively solve not enough and the defect that prior art exists.

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

a pair of pull-up pants capable of avoiding urine leakage comprises a pants body, an elastic waistband, a fabric layer forming the pants body and leg sleeving holes formed in two sides of the pants body; the edge position of the leg covering hole is provided with an edge leakage prevention frill for preventing urine from leaking laterally, and the outer edge of the edge leakage prevention frill is provided with a flexible lace; the middle part of the inner surface of the lower part of the trousers body is provided with an inner groove for collecting urine and guiding the urine, and the outer surface of the lower part of the trousers body is provided with an outer bulge; a liquid absorption core with a porous structure is arranged inside the lower part of the trousers body, water absorption particles are filled above the liquid absorption core, and a moisture absorption cotton layer is arranged below the liquid absorption core; and a liquid suction rod is arranged inside the outer bulge.
