ABSTRACT:
A method and means for fabrication of a relatively low cost display or communicative novelty button in which a consumable restrictor sheet is placed over a vacuum draw type female mold cavity. The restrictor sheet may be of cardboard and be apertured with a diameter smaller than the mold cavity diameter. A thermoplastic sheet material is then placed over the restrictor sheet, heated to reach a formable state and vacuum drawn through the restricted aperture and down so that the sheet comes into contact with and generally conforms to the desired shape defined by the mold cavity. The plastic sheet material may then be trimmed near the edge of the restrictor sheet to leave a button shell mounted on a restrictor sheet which may then be used for purposes of display. The restrictor sheet also enables fabrication with an inwardly facing peripheral groove that may be used to secure a pin fastener. An alternate form of fastener in which a portion of the remaining plastic sheet is used is also disclosed.
