Abstract

A breathable and impermeable diaper, comprising a diaper body (1) that is composed of at least two absorbent composite layers and an impermeable layer, a plurality of through holes (2) being provided at a middle portion of the diaper body (1), and a breathable and impermeable device being embedded in each through hole (2). The breathable and impermeable device is a 工-shaped cylinder (5), and a flow blocking layer (8) is provided at a lower bottom portion of the 工-shaped cylinder (5), while a plurality of ventilation holes (7) are provided on the flow blocking layer (8). The breathable and impermeable diaper has good air-permeability and fluid-impermeability, solves the problems in existing diapers wherein air permeability is poor, temperature is high and moisture is high, and has a simple structure and low production costs.

Description

Breathable and impervious diaper

First, the technical field:

The invention relates to diaper, in particular to a diaper that is breathable and impervious.

Second, the background technology:

Diapers, ie diapers, are disposable escorts that are used in large quantities in infants and adults. They are mainly used to absorb urine from infants and the incontinence of the elderly. Because the diaper is convenient to carry, does not need to be cleaned, and is easy to replace, it is deeply loved by people, and it brings great convenience to people's daily life.

However, nowadays, all brands in the domestic and international markets have a technical bottleneck that has not been broken yet. That is, the air permeability is poor, the temperature is high, and the humidity is high. This environment is an ideal hotbed of bacteria, which is easy to cause use. Skin diseases such as eczema and atopic dermatitis, as well as genital inflammation and digestive diseases, are especially serious in men with testicular damage. "Urine and Social Change - Chemistry and Society" pointed out that the child's genitals are always trapped in a small space, the heat is difficult to dissipate, so it affects the normal development of the testes and genitals. Developed countries in Europe and the United States have used diapers for a long time, forming a "urinary non-wet generation", while Asians use less time, so the fertility of Europeans and Americans is lower than that of Asians.

Because of the health of infants and young children, the future of our people. Therefore, in order to protect human health, especially the reproductive health of infants and young children, it is the mission and pursuit of every scientific and technological worker in this field to completely solve the problem of poor diaper permeability, high temperature and high humidity.

Third, the invention content:

The technical problem to be solved by the present invention is that the present invention provides a ventilated and diarrhea-resistant diaper against the problems existing in the existing diaper. The ventilated and impervious diaper of the invention can effectively solve the technical problem that the existing diaper has poor gas permeability, high temperature and high humidity.

In order to solve the above technical problems, the technical solution adopted by the present invention is:

The invention provides a permeable and diarrhea-free diaper, comprising a diaper body, the diaper body comprising at least two layers of an absorbent composite layer and a layer of an anti-seepage layer, wherein: the middle portion of the diaper body a plurality of through holes are arranged, and each of the through holes is respectively provided with a gas permeable and anti-seepage device; the gas permeable and anti-seepage device is an I-shaped cylinder, and a baffle layer is arranged at a lower bottom of the I-shaped cylinder, and the resistance is A plurality of vent holes are provided in the flow layer.

According to the above-mentioned ventilating and impervious diaper, the I-shaped cylinder is composed of an upper ring, a lower ring, and a cylinder connecting the upper ring and the lower ring.

According to the above-mentioned ventilated and impervious diaper, the size of the upper ring is smaller than the size of the lower ring.

According to the above-mentioned ventilated and diarrhea-resistant diaper, the vent hole has a pore diameter of 0.1 mm to 10 mm.

According to the above-mentioned ventilated and impervious diaper, the ventilating anti-seepage device is made of silica gel.

The invention adopts the above technical solution to design a ventilated and impervious diaper, because a plurality of through holes are arranged in the diaper body, and each through hole is embedded with a ventilating anti-seepage device, and the ventilating anti-seepage device For the I-shaped cylinder, the bottom of the I-shaped cylinder is provided with a baffle layer, and the baffle layer is provided with a plurality of venting holes, which can pass through the I-shaped cylinder and the vent hole, and can be used well when the urine is not wet. The ground is ventilated, and because the vent hole has a small aperture, under the action of the liquid surface tension, the urine that penetrates into the vent hole does not ooze out from the vent hole, and has the dual functions of venting and anti-seepage. The invention has the advantages of simple urinary structure and low production cost, and better solves the problems existing in the existing diaper.

Fourth, the description of the drawings:

Figure 1 is a schematic view showing the structure of a breathable and impervious diaper of the present invention;

Fig. 2 is a cross-sectional structural view showing the gas permeable and anti-seepage device of Fig. 1.

V. Specific implementation methods:

Hereinafter, a breathable and impervious diaper of the present invention will be specifically described with reference to the accompanying drawings.

Referring to Figure 1 and Figure 2, the present invention is a breathable impervious diaper comprising a diaper body 1 composed of at least two layers of an absorbent composite layer and a barrier layer, in the diaper body 1 A plurality of through holes 2 are formed in the middle, and a gas permeable and anti-seepage device made of silica gel is embedded in each of the through holes 2. The breathable anti-seepage device of the present invention comprises an upper ring 3, a lower ring 6 and an I-shaped structure connecting the upper ring 3 and the lower ring 6 with a cylinder 5, and a baffle layer is arranged on the ring of the lower ring 6. 8. The permeable layer 8 is provided with a plurality of venting holes 7, each of which has a diameter of 0.1 mm to 10 mm. The size of the upper ring 3 of the present invention may be smaller than the size of the lower ring 6.

When in use, the user's urine is absorbed by the absorbing composite layer, and a plurality of venting holes and through holes on the venting and anti-seepage device function as a gas permeable, which can cool and dehumidify well. If the urine penetrates into the through hole in the gas permeable and anti-seepage device, since the vent hole is a micro hole, under the action of the surface tension of the liquid, the urine does not easily escape from the vent hole, thereby preventing the penetration.
