This utility model relates to the field of personal care products technology, specifically a front-flow design structure for disposable diapers to prevent soiling. It includes a diaper body and an elastic barrier band structure positioned on the inner absorbent layer of the diaper body. The elastic barrier band structure starts from the outer side of one waist, extends through the groin area on the same side to the perineum, and then extends to the outer side of the other waist. This utility model, by setting the elastic barrier band structure in a three-dimensional "∞" shape, can divide the interior of the diaper body into independent rear and front areas. This innovative design effectively prevents feces and other stains from overflowing from the rear area to the front, avoiding the soiling spread problem common in traditional diapers. For example, during use by infants or adults, when excrement accumulates in the rear area, the elastic barrier band structure acts as a barrier.

This product is a disposable diaper that is wrapped around a pet. This product is characterized by a fastening portion at one end and multiple elastic threads in the area between the fastening portion and the absorbent portion. This configuration improves ease of application and fit. Furthermore, the multiple elastic threads tend to cause wrinkles in this area. The skin-facing sheet and leak-preventing gathers of this product are made of thin nonwoven fabric and are therefore translucent, allowing the structure visible inside and beyond to be seen through. As shown in the "Reference Diagram Showing the State of Use," the diaper is wrapped around the pet's abdomen, with the gathers on the hind legs positioned between the genitals and testicles. Because this product is primarily made of thin nonwoven fabric, wrinkles may appear throughout the product.
