[0003]
[Problems to be solved by the invention]
When the pants-type diapers are removed while standing, excrement may adhere to the wearer's legs and soil the clothes and surroundings. This is because the pants-type diapers are generally removed from one of the side edges where the front and back bodies are joined, so that the crotch part where excrement is attached becomes unstable. , The excrement on the top sheet, because the entire diaper is difficult to handle with one hand of the person attaching and detaching (because the other hand is on the side edge when removing the diaper using the pants type) This is because the movement and scattering of the urine occurs, and the excrement easily leaks to the surroundings.
In addition, when disposing of pants-type disposable diapers consisting of an absorbent main body and an exterior member as garbage, the absorbent main body should preferably be sealed in the home due to odors from excrement and hygiene problems. However, the exterior member can be handled as general waste if no excrement is attached. However, if the absorbent main body and the exterior member cannot be removed, it is necessary to take care to seal them together, and it is not preferable that the amount of dust increases from the viewpoint of hygiene.
[0004]
The object of the present invention is to solve the above-mentioned problems, enabling the absorbent main body to be removed while wearing, and when removing the diaper while standing, excrement adheres to the wearer's leg, An object of the present invention is to provide a pants-type disposable diaper that can prevent leakage and reduce the amount of garbage to be sealed in the home.
