[0004]
[Problems to be solved by the invention]
Provided is a disposable diaper that can be disposed of in a sanitary manner without disturbing a feeling of wearing or being erroneously broken by providing a disposal means in a part that does not adhere to the body when worn.
[0005]
[Means for Solving the Problems]
The present invention provides a slit-shaped or other opening extending in the longitudinal direction of the pants body or a slit for forming a strip portion from one side or forming these openings or notches between the widthwise edges of the front and rear waist portion of the complete pants and the side seal. The present invention relates to a pants-type disposable diaper having perforations that can be formed.
[0006]
In addition, the present invention provides a slit-like or other opening extending in the longitudinal direction between the widthwise edge of the front and rear waist portion and the side seal or a cut for forming a strip from one side or a perforation capable of forming these openings or cuts. The present invention relates to a structure for sanitary disposal of pants-type disposable diapers.
[0007]
A slit-shaped opening or the like extending in the longitudinal direction of the pants body is provided between the widthwise edges of the front and rear waist parts of the complete pants and the side seals. Alternatively, one side may be cut to form a strip portion.
(1) The opening may be in either the width direction and / or the front-rear direction of the front and rear waist end portions of the pants body, but can be used even if the side seal portion is not broken if both penetrate. Is more preferable.
(2) The distance (W) between the width direction end of the pants body and the side seal portion is 10 to 60 mm. By being in this range, it is possible to obtain pants that are easy to process and have less discomfort when worn.
(3) The size of the opening is preferably 50 to 95% of the length of the side seal portion (L ₁ ) in the longitudinal direction, and more preferably 70 to 85% in terms of ease of processing and strength. It is.
(4) In order to reinforce the opening, reinforcing members may be arranged outside the both ends of the opening or on the periphery of the opening.
Examples of the reinforcing member include the following.
-An elastic member that improves fit around the waist extends from the side seal to the outer edge of the pants in the width direction.
-An elastic film is arranged at the site.
And so on.
[0008]
[Action]
When the diaper is discarded, a rounded diaper is passed through this opening and fixed. Alternatively, in the case of a cut, the strip portions are connected to each other and kept in a rounded state. Thereby, the treatment can be performed hygienically.
[0009]
【The invention's effect】
{Circle around (1)} By providing the disposal means in a portion that does not adhere to the body when worn without being affected by gathers on the legs and waist, the feeling of wearing is not hindered. In addition, there is no possibility of being unusable due to being broken by mistake.
(2) Since a processing member such as an adhesive tape is not used, it is advantageous in terms of cost.
(3) It is easy to pull up and pull down the pants-type diaper by grasping the outer part of the side seal portion.
[0010]
