A method for manufacturing a hollow protruding implement () including a fine hollow protrusion () having an opening () of the present invention includes a protrusion forming step of inserting a projecting mold part () into a base material sheet (A) from one face (D) side thereof, the base material sheet containing a thermoplastic resin, thereby forming a non-penetrated hollow protrusion () projecting from another face (U) side of the base material sheet (A). Subsequently, an opening forming step is performed in which an opening () that penetrates the hollow protrusion () is formed by using a contactless opening forming means disposed on the other face (U) side of the base material sheet (A).

A pull-on diaperB of the invention includes an outer cover assemblydefining the exterior surface of the diaper. A front body portion F and a rear body portion R of the outer cover assemblyare connected to each other along their laterally opposite side edges to form a pair of side seams, a waist opening, and a pair of leg openings. Each side seamhas a sealed edge portionwhere the front body portion side edgeF and the rear body portion side edgeR of the outer cover assemblyare bonded to each other at a continuous linear fusion bond extending in the longitudinal direction of the side seam and, in part, a non-sealed portionwhere the front body portion side edgeF and the rear body portion side edgeR of the outer cover assembly face to each other in a non-bonded relationship.

Absorbent article with fusion bonded side seams

A pull-on garment () includes an outer cover () forming an outer surface of the garment, both lateral side edge portions of the outer cover in a front body portion F and both lateral side edge portions of the outer cover in a back body portion R being joined to each other to form a pair of side seals (), a waist opening (), and a pair of leg openings (). Each of the side seals () includes a seal edge portion () where the edge portion (F) of the outer cover () in the front body portion F and the edge portion of the outer cover () in the back body portion R are bonded to each other by a continuous linear fusion-bonded portion () extending in a longitudinal direction of the side seal (). In a cross-section orthogonal to a direction in which the side seal () extends, the fusion-bonded portion () includes a narrow section (F) which is formed at a middle portion thereof in the thickness direction Q and of which a width W along the inner-to-outer direction P is small. The narrow section (F) includes broad sections (A,B) which are provided on both sides of the narrow section (F) in the thickness direction Q and of which the width W is larger than the width of the narrow section (F).

Pants-type wearing article and production method for same

In the present invention, one surface of a belt-shaped sheet laminate (), in which a plurality of sheets are laminated, is pressed against a support member () having a light passage section () through which a laser beam () can pass, and the belt-shaped sheet laminate () is irradiated, from the support member () side via the light passage section (), with a laser beam () to cut and fusion-bond the belt-shaped sheet laminate (), thereby sealed edge sections () are formed by fusion-bonding the edge sections of the plurality of sheets.

Method for manufacturing fused sheets

A hair sensor, which can suppress mixing of external noise to a minimal level when a sliding sound of hair is detected, amplified, and output as an audio output in order to estimate surface characteristics and the degree of hair damage, and which can be easily used, is provided. The hair sensor for detecting the sliding sound of the hair in order to estimate hair characteristics includes a sliding element capable of sliding on the hair and a housing which includes a microphone provided therein. The sliding element is erected on a diaphragm. The sliding element and the diaphragm are arranged to allow the sliding sound caused by the sliding element to be transmitted through the diaphragm to the microphone and to attenuate vibration transmitted from outside of the diaphragm to the microphone. The surface of the sliding element is preferably treated to have a roughened surface in order to improve slidability thereof during measurement and measurement accuracy.
