Publication number: 20230232944Abstract: A top stop for a slide fastener includes a first body portion, which includes a channel having an inlet at a first side of the top stop and an outlet at a second side of the top stop. The channel is defined by a channel first side wall and a channel second side wall, and a channel bottom surface therebetween. The channel second side wall includes a protruding portion, which defines an abutment protrusion in the channel. A distance parallel to the longitudinal axis of the top stop between the channel first side wall and channel second side wall defines a channel width. The channel width extending from the abutment protrusion to the channel first side wall is less than the channel width at the inlet and the channel width at the outlet.Type: ApplicationFiled: June 22, 2021Publication date: July 27, 2023Inventors: Alicia Treacy, Shigeyoshi Takazawa, Matthew Rawstron
