Description

Core, absorptive main body and menstrual period trousers capable of preventing rear leakage

Technical Field

The utility model relates to the field of hygienic products, especially, relate to a core, absorptive main part and prevent leaking menstrual period trousers after.

Background

The menstrual period trousers are underpants specially for women to wear in the physiological period, the most different point of the structure of the conventional menstrual period trousers from that of the common underpants is that the menstrual period trousers are made of cloth (such as nylon cloth) which is difficult to absorb water and permeate in the crotch part and the back area or made of cloth which is subjected to anti-seepage treatment, and when menstrual blood leaks from sanitary cotton adhered to the inner surface of the menstrual period trousers, the menstrual blood can be prevented from permeating outwards to contaminate the outer skirt or trousers of the women, so that embarrassment and embarrassment are caused.

The bacteriostatic allergy-free menstrual period trousers with the dumbbell type absorption core body are disclosed in Chinese utility model patent publication text with the publication number of CN213130331U and can be referred to in the structure of the conventional menstrual period trousers, and comprise a pants type menstrual period trousers body, the menstrual period trousers body is obtained by bonding a surface layer non-woven fabric, an absorption core body and a bottom film from inside to outside in sequence, wherein, the surface layer non-woven fabric is sprayed with bacteriostatic liquid, the front end of the absorption core body is provided with a first leakage-proof absorption block which is dumbbell type, and the rear end of the absorption core body is provided with a second leakage-proof absorption block which is big fan tail type.

Further, the text states: the cotton core in the absorption core body is rectangular, and the front end of the dust-free paper positioned on the upper layer of the cotton core is provided with a dumbbell-shaped first leakage-proof absorption block, so that the problem of leakage before menstrual blood can be effectively prevented by a dumbbell-shaped structure at the front end. However, when a woman sleeps at night by using the product, menstrual blood mainly flows to the rear crotch part, the rectangular cotton core is difficult to quickly permeate and absorb the menstrual blood, and the situation that the menstrual blood quickly flows to the edge of the absorption core body and is not absorbed in time to cause back leakage easily occurs.

Disclosure of Invention

In order to solve the above problem, a first object of the present invention is to provide a core body, which can play the effect of blocking menstrual blood and fast absorption, thereby avoiding the leakage of menstrual blood from the rear end of menstrual pants.

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

a core body comprises a body made of water-absorbing particles; the method is characterized in that: a bulge part protruding upwards the body is arranged in the rear side area of the middle part of the main body, and a groove area with an opening facing to the front side is formed at the front end of the bulge part; the rear end edge of the groove area at least extends to the rear side of the midline of the body.

The utility model adopts the above technical scheme, this technical scheme relates to a core, this core is on the basis of rectangle main part, and the middle part rear side region upwards protrudes and forms the bellying, and the bellying has increased the thickness in this region of core on the one hand, promotes the core absorbed volume; on the other hand, a groove area with an opening facing to the front side is formed at the front end of the protruding part, and based on the arrangement of the groove, the effects of collecting, blocking and buffering the menstrual blood or urine can be achieved, and the menstrual blood can be prevented from flowing to the rear side edge of the absorption core body quickly. The increased absorption amount matched with the convex part can play the effects of blocking menstrual blood and quickly absorbing the menstrual blood, thereby avoiding the problem that the menstrual blood leaks from the rear end of menstrual pants.
