Disposable diaper

Abstract

The present invention provides a disposable diaper comprising extendible side flaps respectively extending from an end portion in a lengthwise direction of a diaper main body, an attaching tape with hook member and disposed at an edge of the respective side flaps, the attaching tape is provided with a hook member, the attaching tape being temporarily engage-able with the side flaps. The solution of the present invention is a disposable diaper in which the attaching tape is provided in the vicinity of side edges of a pair of side flaps arranged along the lengthwise ends of a diaper body. The attaching tape is provided with the hook member while the side flaps are provided with a region (an engaging region) on the side flaps where the attaching tape engages. The engaging region is constituted by an engaging portion with which the hook member engages and a non-engaging portion which has a very weak engagement effect or no engagement effect. As such, the attaching tape can be temporarily fixed with a modest engaging force, despite the hook member having a greater engaging force.

Description

technical field [0001] The present invention relates to a disposable diaper having a tape-shaped adhesive member, and more particularly, the present invention relates to a pair of side flaps arranged at the ends along the longitudinal direction of the diaper main body, provided with a Disposable diapers with adhesive tape for hook fastening components. Background technique [0002] Commonly used disposable diapers are composed of an absorbent body located between the top sheet and the back sheet and arranged to cover the crotch of the wearer when worn, and its shape is in the shape of a substantially rectangular long side. The center part on the direction side is formed in an hourglass shape with a recessed part. This concave portion constitutes the crotch portion, the side connected to the crotch portion and enlarged constitutes the back portion, the other side constitutes the ventral portion, and in the lateral direction of the two wings of the dorsal portion Adhesive st...

Problems solved by technology

[0009] However, when the two flaps of the disposable diaper are made of stretchable side flaps, due to the stretchability of the side flaps and the fluffy non-woven fabric on the surface, In the case of temporarily fixing with hook-type fastening parts, the bonding force between the hook-type fastening parts and the fluffy non-woven fabric will be relatively strong. tape peels off and may damage the surface of the side flaps

[0010] In addition, a temporary fixing adhesive may be applied to a position near the hook-shaped fastening member, and the hook-shaped fastening member is folded back toward the inside to perform temporary fixing with the temporary fixing adhesive. However, when this method is temporarily fixed, it is necessary to increase the new process of applying the adhesive for temporary fixing in advance, so there are problems such as making the manufacturing process complicated, and there are also shortcomings such as increased manufacturing costs.
