Description

An ultra-thin composite structure and diaper that automatically transfers urine in a directional manner

Technical field

The utility model relates to the technical field of absorbent articles, and more specifically, to an ultra-thin composite structure and diapers that automatically transfer urine in a directional manner.

Background technique

Diapers are one of the most common necessities in daily life. They are care products designed for babies, middle-aged and elderly people and patients. Diapers can absorb the user's urine and excretion, keeping them dry and comfortable, thereby improving sleep quality and reducing the burden on caregivers. Due to the convenience and quickness of diapers, the demand and application scope of diapers are increasing day by day. For existing diapers, urine usually seeps down in the vertical direction and is absorbed by the absorbent core. In other words, urine seeps down from the surface layer of the diaper close to the skin to the absorbent core and is absorbed. Moreover, in order to allow the liquid to better reach the absorbent core, the non-woven fabric of the surface layer is mostly hydrophilic non-woven fabric; however, this type of hydrophilic non-woven fabric will cause the urine to be absorbed and contact with the skin. There will still be a feeling of moisture when reaching the surface layer; and after multiple uses of this type of existing diapers, urine will leak back.

Although some technologies currently propose using hydrophobic materials on the side close to the skin and designing some special structures to solve the above-mentioned problems of diapers, there is still a risk of excessive accumulation of urine and back seepage to the skin-friendly side. In addition, since the absorbent core on the middle side of the crotch will expand in volume after absorbing water, it will directly affect the wearing comfort. Therefore, in addition to the above-mentioned shortcomings, common diapers in the prior art also need to be improved in terms of wearing comfort.

The existing technology is in urgent need of an absorbent structure or diaper that can be applied to diapers to solve the shortcomings of the existing diapers.

One purpose of this utility model is to provide an ultra-thin composite structure for automatic directional transfer of urine, that is, a rapid directional liquid diffusion composite structure, including a liquid conduction structure, an absorption assembly and a liquid suppression structure; the absorption assembly The body is disposed at the end of the liquid conduction structure; the liquid conduction structure is connected to the absorption assembly; and the surface of the absorption assembly is provided with a liquid isolation structure; the liquid suppression structure is disposed beside the liquid conduction structure. Further, both ends of the liquid conduction structure are connected with absorption aggregates. The liquid conduction structure has a long side and a short side, the absorption assembly is provided at the short side end, and the liquid suppression structure is provided next to the long side. The liquid conduction structure receives the liquid and guides it to the absorption assembly at the end, and the liquid suppression structure inhibits the liquid received by the conduction structure from flowing to the side of the liquid conduction structure.

When the liquid conduction structure receives the liquid, the liquid spreads laterally toward both ends along the liquid conduction structure, and under the action of the side liquid suppression structure, the liquid will not spread in the side direction of the liquid conduction structure. The absorption assembly is located at the end of the liquid conduction structure and connected thereto, and can quickly absorb the liquid transmitted along the liquid conduction structure.

Furthermore, when the ultra-light and thin composite structure for automatically directional urine transfer is applied to diapers, both ends of the liquid conduction structure are connected to the front waist and rear waist of the diaper respectively. Through the configuration of the liquid conduction structure in the length direction of the diaper and the liquid suppression structure arranged in the width direction of the diaper, urine can be directed and quickly conducted to the corresponding positions at both ends of the liquid conduction structure; the cooperation with the liquid conduction structure is located at The water-absorbent aggregate with a liquid-isolating structure on the same level can effectively solve the problems of poor comfort and reverse osmosis of urine in the existing technology, and has a simple functional structure.
