Description

Technical Field

[0001] The invention relates to the field of sanitary care, in particular to a pair of disposable sanitary pants with improved sweat absorption and ventilation functions. Background Art

[0002] At present, disposable sanitary pants such as diapers (such as pull-up pants) and female physiological pants are widely used for infant protection, women's physiological period, and for solving the problem of urinary incontinence in the elderly. Infants and elderly people with urinary incontinence spend a lot of time sleeping or lying in bed, and are often in a lying state. Infants have well-developed sweat glands and sweat a lot. In the case where the waist of the diaper is an elastic band, since the surface of the elastic band is relatively rough, if the diaper is not changed in time, the sweat at the back waist is easy to accumulate and difficult to discharge. If this happens, the sensitive skin of the baby is damaged due to friction, which leads to bacterial invasion, and then causes skin rashes and bacterial infections. At the same time, if the ventilation and air permeability of physiological pants of women during their menstrual period is not good, it is also easy to breed bacteria.

[0003] At present, some sanitary pants products on the market have designed pocket structures on the back waist, but the materials used are mostly non-woven fabrics made of petrochemical fibers. Therefore, such diapers are not soft enough and have poor sweat absorption and moisture discharge properties. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a disposable sanitary trousers, the rear waistline of which has the functions of absorbing sweat, preventing urine leakage and ventilating.

[0005] According to the present invention, a disposable sanitary pants is provided, which has a crotch portion, a rear waistline, and a front waistline, wherein a waist elastic band is arranged inside the rear waistline, and the disposable sanitary pants further has a pocket arranged on the inner surface of the rear waistline.

[0006] Preferably, the longitudinal width of the pocket is the same as the longitudinal width of the rear waistline.

[0007] Preferably, the pocket is made of cotton, rayon, silk or linen.

[0008] Preferably, the pocket surface has a plurality of ventilation holes.

[0009] Preferably, the transverse aperture of the ventilation hole is 0.7 mm-1.7 mm, and the longitudinal aperture of the ventilation hole is 0.7 mm-1.5 mm.

[0010] Preferably, the pocket is fixed to the inner surface of the rear waistline in a manner that the upper edge thereof has pleats.

[0011] Preferably, the transverse length of the pocket is smaller than the transverse length of the rear waistline and larger than the transverse length of the upper edge of the crotch.

[0012] Preferably, the material of the rear waistline, the crotch part and the front waistline is non-woven fabric.

[0013] Preferably, the upper edge, left edge and right edge of the pocket are fixed on the inner surface of the rear waistline, and the lower edge of the pocket is not fixed. Preferably, the upper edge, left edge and right edge of the pocket are adhered to the inner surface of the rear waistline by glue.

[0014] The disposable sanitary pants of the present invention have the following technical effects:

[0015] A pocket is provided on the inner surface of the rear waist of the disposable sanitary pants. The water-absorbing surface of the pocket is in close contact with the rear waist of the human back, and sweat or urine is immediately absorbed when it reaches this position, so that the user's skin remains dry and clean. The pocket is made of natural or naturally derived cellulose material, which is close to the skin and environmentally friendly, so it can reduce the friction between the disposable sanitary pants and the corresponding part of the human body. At the same time, compared with petrochemical-derived polymer materials, the material has lower skin allergy, so it can reduce allergic reactions. And the material has relatively excellent moisture absorption performance, so that the user does not feel the temperature difference when discharging body fluids or sweat, and can also prevent problems such as diaper rash or bacterial infection.

[0016] In addition, when used in women's sanitary pants, the vent structure design on the pocket surface has a ventilation and breathable effect.

[0017] In addition, the pocket is open at the bottom to prevent feces from leaking out. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 1 is a front view showing the disposable sanitary pants of the present invention in an unfolded state.

[0019] Figure 2 It is an enlarged view of the pocket 12 of the disposable sanitary pants of the present invention. DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings. In the following description, in order to determine the direction, expressions such as "up and down" are used, such as Figure 1 As shown, in the present invention, the direction perpendicular to the length direction of the rear waistline is defined as the longitudinal direction, that is, the up-down direction, wherein the direction toward the rear waistline is "up", the direction toward the front waistline is "down", and the direction perpendicular to the up-down direction is defined as the lateral direction. These expressions are used for the convenience of description and do not limit the scope of protection of the present invention.

[0021] Figure 1It is a front view of the disposable sanitary pants of the present invention in the unfolded state. The disposable sanitary pants 10 of the present invention include: a crotch portion 11, a rear waist circumference 13, and a front waist circumference 14, and the pocket 12 is arranged on the rear waist circumference 13. When in use, the two ends of the front waist circumference 14 are fitted with the two ends of the rear waist circumference 13 to form a three-dimensional disposable sanitary pants. Among them, a waist elastic band is arranged inside the rear waist circumference 13; the pocket 12 is attached to the inner surface of the rear waist circumference 13 with glue in a manner of opening on three sides. Preferably, the upper edge, left edge and right edge of the pocket are fixed on the rear waist circumference 13, and the lower edge is not fixed. Since the lower edge of the pocket 12 is not fixed, its surface can be affected by the elasticity of the waist in the horizontal direction, thereby producing a gradual wave shape or curtain effect, which can softly contact the skin and adhere to the skin surface.

[0022] The material of the pocket 12 is a natural or naturally derived cellulose material, preferably cotton, rayon, silk or linen. This is because natural cellulose materials such as cotton have a higher water absorption rate. For example, cotton absorbs 10% to 14% of water vapor, while polyester can only absorb 1%, and polypropylene is even less. The outer layer material of disposable absorbent articles in the prior art is mostly made of polypropylene. Therefore, using natural or naturally derived cellulose materials in disposable articles will help absorb body fluids such as sweat.

[0023] Preferably, the surface of the pocket 12 has a plurality of densely distributed ventilation holes, which are regularly arranged in a mesh structure on the surface of the pocket 12 to ensure the ventilation and air permeability of the disposable sanitary pants of the present invention when used as female physiological pants. Further, the transverse aperture of the ventilation hole is 0.7 mm-1.7 mm, and the longitudinal aperture of the ventilation hole is 0.7 mm-1.5 mm.

[0024] Preferably, the pocket 12 is fixed to the back waist 13 in a manner that the upper edge has curtain-like pleats. The pocket 12 with a pleated structure has a larger area of ​​absorbent material than the pocket 12 pasted flatly, and has a better absorption effect on urine leakage from the back.

[0025] Preferably, the longitudinal width of the pocket 12 is the same as the longitudinal width of the rear waistline 13. Preferably, the transverse length of the pocket 12 is less than the transverse length of the rear waistline 13 and greater than the transverse length of the upper edge of the crotch portion 11.

[0026] Preferably, the materials of other parts of the disposable sanitary pants 10 except the pocket 12 are all non-woven fabrics.

[0027] Conventional disposable sanitary pants, especially diapers with elastic waistbands, often cause diaper rash on the skin of the user's back that contacts the waistband, because the surface of the waistband with elastic waistbands is relatively rough and is made of petrochemical non-woven fabrics. In the present invention, since the pocket 12 is located on the surface of the back waistband 13, the surface of the pocket 12 is in close contact with the back waist portion of the human body, and can absorb sweat and / or urine immediately when it occurs, so that the user's skin remains dry and fresh, and ultimately prevents diaper rash.

[0028] Preferably, the pocket 12 has a downward opening, and the other three sides are fixed to the rear waistline 13 by glue, so as to prevent urine, feces and the like from leaking out of the rear waistline 13.

[0029] Furthermore, preferably, the pocket 12 is fixed to the back waist circumference 13 in a manner that the upper edge has curtain-like folds. Therefore, soft and silent wave patterns are produced during the bonding, which is relatively beautiful and can further increase the adsorption effect.

[0030] Figure 2 yes Figure 1 The enlarged view of the middle pocket 12 is shown below. Figure 2 The fixing method of the pocket 12 of the disposable sanitary pants 10 of the present invention and the back waist circumference 11 is specifically described. The pocket 12 has an upper edge 12b, a left edge 12a and a right edge 12c. When fixed, glue is applied to the upper edge 12b, the left edge 12a and the right edge 12c with a certain width, and is attached to the surface of the back waist circumference 13. The lower edge is not glued and is in an open state.

[0031] The above content only represents a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
