Background
Urinary incontinence is a phenomenon in which the urination function cannot be controlled by consciousness and urine flows out involuntarily through the urethra. Only a small urine leakage is called mild incontinence, although a small amount of urine leakage does not mean that the discomfort experienced by the affected person is not severe. In addition to medical treatment with a physician, it is necessary to use incontinence articles during treatment to protect the wearer from urine leakage. The traditional light incontinence products are generally used by both men and women, have basically the same structure as the sanitary towel, and do not consider the difference of physiological structures between men and women, so that the comfort experience of male wearers is poor in the using process, and the urine absorption effect is poor. There is therefore a need to develop incontinence articles specifically for mildly incontinent men that meet the objective needs of the population.

The utility model is designed to meet the physiological characteristics of male men and increase the absorption of urine, so as to accelerate the diffusion and permeation of urine and avoid the leakage phenomenon.
Chinese patent application No.: 201922487369.0 discloses a male mild incontinence diaper, including surface course, absorbent layer, basement membrane, gum layer, from type paper and guiding gutter, the diaper is by inside outwards being surface course, absorbent layer, basement membrane, gum layer and from type paper in proper order, and the guiding gutter sets up between surface course and absorbent layer, and the surface course is the innermost layer, contacts with human skin, gum layer and patient's pants laminating are from type paper setting outside the gum layer, and is outmost for the diaper, when patient's incontinence, liquid is diffused rapidly by the guiding gutter, at first soaks the surface course, then is absorbed by the absorbent layer, and the PE membrane of bottom can effectively separate liquid, makes liquid store in the absorbent layer. The utility model discloses a top layer, absorbent layer and bottom are low areal density, whole light in weight to compact the absorbent layer through the pressure roller, make absorbent layer thickness minimum be 0.08cm, the whole diaper thickness of greatly reduced is worn and is hidden good.
Chinese patent application No.: 201922433247.3 discloses a mild adult incontinence product, which comprises a soft surface layer, a flow guide layer, an absorber, a bottom film layer and release paper, wherein the flow guide layer and the absorber form an inner core, the formed inner core is clamped between the soft surface layer and the bottom film layer, a double-sided adhesive tape is adhered to the bottom of the bottom film layer, the release paper is arranged below the bottom film layer and covers the double-sided adhesive tape, the middle part of the soft surface layer is an absorption area, permeation holes are uniformly distributed at the positions of the absorption area corresponding to male testicles and pudendums, lateral leakage-proof grooves are symmetrically arranged at the front and back of the surface of the absorption area, and the lateral leakage-proof grooves are downwards penetrated and arranged in the lateral leakage-proof grooves; the mild incontinence article is specially designed for adult men, and can effectively receive urine leakage.
However, after a male patient wears these male incontinence articles, the incontinence articles do not guarantee that the desired shape is always present in different situations, such as walking around or sitting down, providing optimal incontinence protection and wearing comfort.
Disclosure of Invention
Therefore, in view of the above, the invention provides a male mild incontinence towel with a rigid three-dimensional structure, which solves the problems that the existing incontinence product has poor wearing comfort and can not be well attached to underpants, and effective incontinence protection can be provided all the time.
In order to achieve the purpose, the invention is realized by the following technical scheme:
a male mild incontinence towel with a rigid three-dimensional structure comprises an incontinence towel body, a longitudinal direction and a transverse direction, wherein the longitudinal direction is defined along the length direction of the incontinence towel body, the transverse direction is defined along the width direction of the incontinence towel body, the incontinence towel body comprises a skin-friendly surface layer, a flow guide layer, an absorption core body and a leakage-proof bottom layer which are sequentially laminated from top to bottom, a shaping layer is arranged between the flow guide layer and the absorption core body, the shaping layer comprises an upper non-woven fabric and a lower non-woven fabric, a net-shaped gasket with rigidity strength is arranged between the upper non-woven fabric and the lower non-woven fabric, the incontinence towel body is provided with a first folding line in the longitudinal direction, the first folding line is superposed with the longitudinal central axis, be equipped with the bonding region on the close skin surface course, coat the hot melt adhesive on the bonding region, the bonding region is located the vertical one side of netted gasket, and when folding up along first fold line, bonding region bonding incontinence piece of cloth body forms three-dimensional boss structure.
