ABSTRACT:
A safety closure device for a bottle or the like is described. The device includes a cylindrical closure element which fits within the mouth of the bottle and which is restrained from flying free of the bottle by a cylindrical retainer collar which fits around the neck of the bottle. The closure element is attached to the collar by a tether strip which is molded integrally with the closure element and the collar and which tears free thereof, except for attachment to the collar and closure element at the ends of the tether. The tether is folded upon itself and when manually torn free, and is long enough to permit the closure element to be withdrawn from the bottle while still remaining tethered to the collar.
