Description

TECHNICAL FIELD

[0001] The utility model relates to an absorbent pad, in particular to an anti-pollution absorbent pad with an anti-leakage edge that can be applied to trousers and prevent liquid from leaking. BACKGROUND

[0002] An absorbent pad is a structure that can absorb liquid and is usually arranged at the crotch of trousers to absorb urine, menstrual blood or other secretions discharged by the human body. Traditional absorbent pads such as sanitary pads, sanitary napkins and diapers are mostly disposable consumables and cannot be reused. In order to respond to the environmental protection trend and reduce the impact of garbage on the environment, manufacturers have begun to develop physiological trousers with waterproof function or conventional absorbent pads that can be arranged at the crotch of trousers.

[0003] In order to achieve the effect, the existing absorbent pad usually has a waterproof layer and an absorbent layer. The absorbent layer absorbs the liquid flowing down from above, and the waterproof layer covers the lower part of the absorbent layer to block the liquid from penetrating downward. Considering the reusability and washability, the absorbent layer and the waterproof layer are mostly connected by a fixing structure such as sewing. Moreover, some manufacturers add a breathable skin-friendly layer above the absorbent layer, which can reduce the discomfort caused by the friction between the user's skin and the absorbent layer and prevent the liquid absorbed by the absorbent layer from being reabsorbed onto the skin.

[0004] However, the thread used for sewing is mostly cotton thread or other thread materials that can easily absorb water. After passing through the water-absorbing layer, the thread will absorb liquid due to the siphon phenomenon, causing backflow and staining the trousers or the skin. When the amount of liquid absorbed is large, the liquid will also seep out through the fixing structure, resulting in poor leakage prevention effect. Moreover, the method of sewing the absorbent layer and the waterproof layer will produce holes on the waterproof layer, reducing the waterproof effect.

[0005] In addition, most absorbent pads are flat in structure, which can easily cause liquid to flow out from both sides of the absorbent pad when the instantaneous flow of liquid is large or when the user is in a certain posture, thereby losing the effect of absorption and leakage prevention.

[0006] The present inventors have actively and continuously developed a utility model that can improve the above problems in view of the fact that the existing absorbent pad can cause liquid leakage due to the sewing method and the flat structure of the absorbent pad can easily cause liquid to overflow from both sides. SUMMARY

[0007] The main purpose of the utility model is to provide an absorbent pad with an anti-leakage edge. The anti-leakage edge and the waterproof layer form a three-dimensional structure, which can retain a large amount of liquid in the structure and provide time for the absorbent layer to absorb the liquid.
