Description

Technical Field

[0001] The invention relates to the technical field of sanitary products, in particular to a menstrual pants and an absorbent core thereof. Background Art

[0002] In the field of women's physiological period care products, menstrual pants, as a new product, are gradually gaining favor among consumers. However, the menstrual pants and their absorbent cores currently on the market still have many deficiencies in design and function, especially in terms of preventing side leakage and absorbing menstrual blood, which are difficult to meet the growing needs of women. Most of the traditional menstrual pants absorbent cores use a single absorbent material with limited absorption capacity. Common cotton or ordinary absorbent paper materials have a slow absorption speed and a small absorption amount when facing a large amount of menstrual blood. This causes menstrual blood to quickly penetrate outside the absorbent core when sleeping at night or when the amount of activity during the day is large, which not only contaminates clothing, but also causes discomfort to the user, seriously affecting the quality of life. For example, when the user turns over at night, the menstrual blood will leak along the flow direction of the body because the absorbent core cannot absorb and lock the menstrual blood in time, causing pollution of bed sheets and pajamas, causing trouble and embarrassment to the user. In terms of preventing side leakage, existing menstrual pants generally lack effective designs. Most menstrual pants simply rely on increasing the width of the absorbent core to try to prevent side leakage, but this method is not ideal. In actual use, the human body has various postures, and menstrual blood can easily overflow from the edge of the absorbent core under the action of pressure and gravity. Especially when the user walks, runs or sits for a long time, the thighs frequently rub against the edge of the absorbent core, which further increases the risk of side leakage. Moreover, the existing anti-side leakage design often does not fully consider the physiological curve of the human body, and cannot fit the body closely, resulting in side leakage from time to time. In addition, after absorbing menstrual blood, the absorbent core of some menstrual pants will have problems of lumping and deformation. This will not only reduce the absorption effect, but also affect the wearing comfort of menstrual pants, making the user feel uncomfortable. The lumpy absorbent core may also move in the menstrual pants, resulting in a weakened local absorption capacity, further exacerbating the possibility of side leakage. As consumers have higher and higher requirements for the quality and function of menstrual care products, the existing menstrual pants and their absorbent cores can no longer meet market demand. It is urgent to develop a menstrual pants and its absorbent core with efficient anti-side leakage function that can quickly and massively absorb menstrual blood, which is of great practical significance for improving the quality of life of women during their physiological period.

[0003] Therefore, it is necessary to design a menstrual pants and an absorbent core thereof with strong practicality. Summary of the invention

[0004] The object of the present invention is to provide a menstrual pants and an absorbent core thereof to solve the problems raised in the above-mentioned background technology.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: A menstrual pants, comprising: a pants body, and a restraint band sewn on the upper part of the pants body.

[0006] According to the above technical solution, the restraint band is made of pure cotton material.

[0007] According to the above technical solution, the surface of the restraint band is provided with a plurality of ventilation holes. Through the ventilation holes opened on the surface of the restraint band, the skin contact of the wearer will not be stuffy and sweaty, and can be ventilated and cool, making the wearer feel comfortable.

[0008] In addition to the above technical solutions, the present invention further includes: An absorbent core for pasting inside the pants body. The absorbent core includes a core body. The top surface of the core body is provided with an absorption groove. An internal absorption layer and a main absorption layer are arranged inside the absorption groove. The main absorption layer is arranged on the top surface of the internal absorption layer.

[0009] According to the above technical solution, the surface of the core body is fixedly installed with front and rear symmetrically arranged wings. The wings are provided with adhesive to strengthen the fit between the core body and the pants body.

[0010] According to the above technical solution, the internal absorption layer adopts a new type of superabsorbent resin. By using the superabsorbent resin, the internal absorption layer can have a higher absorption ratio and a faster absorption speed. After contacting the menstrual blood, it can quickly absorb and form a gel-like state, firmly locking the liquid and preventing backflow. At the same time, it can still maintain good morphological stability after absorption saturation, is not easy to break or deform, and ensures effective prevention of side leakage in various situations.

[0011] According to the above technical solution, the main absorption layer is composed of a skin-friendly non-woven fabric, superabsorbent resin particles and a fluffy non-woven fabric mixed layer. By using the skin-friendly non-woven fabric, superabsorbent resin particles and the fluffy non-woven fabric mixed layer, the main absorption layer can quickly absorb menstrual blood and keep the surface dry, reduce friction with the skin, and at the same time can quickly absorb and lock a large amount of menstrual blood to prevent side leakage caused by local absorption saturation.

[0012] According to the above technical solution, the top surface of the main absorption layer is provided with a diversion groove. The diversion groove is horizontally arranged, and the groove depth of the diversion groove is 0.5 - 1 cm. By providing the diversion groove, side leakage of menstrual blood can be avoided, and the main absorption layer and the internal absorption layer can better absorb menstrual blood.

[0013] According to the above technical solution, a surrounding body is arranged outside the main absorption layer. The surrounding body is arranged on the top surface of the core body. By providing the surrounding body, the phenomenon of side leakage of menstrual blood can be avoided.

[0014] According to the above technical solution, the enclosure is made of non-woven fabric, and the upper surface of the enclosure is provided with an arc surface, so that the wearer will not feel friction and the wearer can wear it comfortably.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. For the present invention, it has high absorption and anti-backflow seepage effects: the superabsorbent resin enables the internal absorption layer to have a high absorption ratio and a fast absorption speed. After contacting menstrual blood, it quickly forms a gel state, firmly locks the liquid, prevents backflow seepage, and has a stable form after absorption saturation, effectively preventing side leakage.

[0016] 2. For the present invention, it has comfortable absorption and anti-side leakage effects: the skin-friendly non-woven fabric, superabsorbent resin particles and fluffy non-woven fabric are mixed to form the main absorption layer, which can not only quickly absorb menstrual blood to keep the surface dry, reduce skin friction, but also lock a large amount of blood to prevent side leakage caused by local absorption saturation.

[0017] 3. For the present invention, it has optimized absorption and anti-side leakage effects: the setting of the diversion groove helps the main absorption layer and the internal absorption layer to better absorb menstrual blood and avoid side leakage of menstrual blood.

[0018] 4. For the present invention, it has comfortable anti-leakage effects: the setting of the enclosure can avoid side leakage of menstrual blood, and the design of its arc-shaped upper surface can reduce the friction with the wearer and improve the wearing comfort. Description of the Drawings
