  • Patent number: 4283815
    Abstract: Conventionally, buttons for covering with fabric consist of a hollow back portion with a stem or the like extending therefrom and a front shell snapped into place over the edge of the back portion with fabric covering the front shell and being clamped between the front shell and the back portion. This front portion often disengages from the back portion and sometimes the fabric is cut and damaged by the sharp edges of the mating portions. Also, the attaching stem often disengages from the back shell as it is not usually integrally formed therewith. One embodiment of the present device utilizes a combination front shell and stem having an inturned peripheral lower edge. An apertured disc engages over the stem and snaps into position with the interior lower edge thus holding the fabric firmly and substantially reducing the possibility of disengagement.
