Abstract
The present invention facilitates visually checking whether or not either end of a cover has been fixedly embedded, by insert molding, properly in a pair of clasps of a setting frame. In a hair curler of the present invention, the outer edge at either end of the cover is fixedly embedded in the pair of clasps, exposed out of the outer side surface of the pair of clasps. According to the method of manufacturing the hair curler of the present invention, the projecting portion with the outer edge side of the cover embedded, in the insert molding of the setting frame, is integrally formed on the outside surface of the pair of clasps, and then is cut off from the pair of clasps together with the outer edge side of the cover embedded in the projecting portion.
Claims12
A hair curler comprising a roller and a rectangular frame-like setting frame having a pair of clasps respectively disposed on first and second sides of said setting frame for radially holding said roller from both of said first and second sides, said setting frame being releasably engaged in an axial direction with either end of said roller and provided with a flexible cover covering at least part of an entire length of about a half of an outer periphery of said roller between said clasps, said cover including first and second ends which are each fixedly embedded by insert molding in a respective one of said pair of clasps of said setting frame, wherein:
- each of said clasps include an outer cut surface portion at a location at which said first and second ends of said cover are respectively embedded thereby providing respective exposed first and second outer edges of said first and second ends of said cover at said outer cut surface portions, with said first and second outer edges each fixedly embedded in a respective one of said pair of clasps.
A method of manufacturing a hair curler comprising a roller, and a rectangular frame-like setting frame with a pair of clasps respectively disposed on first and second sides of said setting frame for holding said roller radially from both of said first and second sides, said setting frame being releasably engaged with either end of said roller in the axial direction of said roller, the hair curler including a flexible cover provided for covering at least part of an entire length of about a half of an outer periphery of said roller between said clasps, and said cover including first and second ends each fixedly embedded by insert molding in a respective one of said pair of clasps of said setting frame, the method including:
- integrally forming a projecting portion with an outer edge side of each of said first and second ends of said cover embedded in an outer side surface of a respective one of said pair of clasps, and thereafter cutting said projecting portion from said pair of clasps together with the outer edge side of each of said first and second ends of said cover embedded in said projecting portion.
