Description

Sanitary towel lengthening piece capable of being dispersed

Technical Field

The utility model relates to the field of disposable absorbent sanitary products, in particular to a flushable sanitary towel lengthening piece.

Background

Sanitary napkins are disposable sanitary products with a strong liquid absorbing capacity and are used mainly for absorbing menstrual blood from a woman when her menstrual is on a tide. According to different using time periods, the prior sanitary towel comprises a daily type sanitary towel and a night type sanitary towel.

The sanitary towel for night use is generally used at night in the premenstrual period, and the female is in a lying sleep state at night, so that the sanitary towel for night use has large premenstrual menstrual blood volume and higher liquid absorption requirement on the sanitary towel for night use. Therefore, the size of the sanitary napkin for night use is generally much larger than that of the sanitary napkin for general daily use. Sanitary napkins with a length of more than 320mm are commercially available as night napkins, which have a relatively large liquid absorption capacity. Some brands even offer ultra-long night napkins of 420mm length. The diameter of the sewer pipe of a common toilet bowl is 100 mm-110 mm, and the large-size night sanitary towel cannot pass through the sewer pipe.

Disposable sanitary products such as sanitary napkins, pads, paper diapers and the like bring convenience to life of people and bring huge pressure to environmental protection. How to dispose of these disposable absorbent sanitary articles after use has become an important issue for consumers and even the whole society. Therefore, development of disposable, degradable health care products has become a hotspot in industry research.

At present, some solutions of dispersible sanitary napkins and sanitary pads have appeared in the industry, and when the solution is applied to a common daily sanitary napkin or sanitary pad, the solution can be dispersed and disintegrated in a short time in a sewer pipe after being put into a toilet bowl due to small volume and small size of the product, and the sewer pipe cannot be blocked. However, the volume and size of the sanitary napkins, diapers, etc. for night use are large, and if the sanitary napkins, diapers, etc. are directly put into a toilet, the toilet and the sewer line are blocked, and the purpose of flushable can not be achieved.
