ABSTRACT:
A spile accommodating plastic lid, having a transverse closure wall, for sealed closure of jars, bottles, pouches and like fluent material conveyances that must be accessed for issuance of material contained therein. The closure wall is provided with a circular breakout area having a frangible periphery that facilitates mounting of a hollow push-in-place spile onto the lid, wherein, a tubular portion of the spile extends through the lid. The breakout area is constructed such that the frangible periphery yields and ruptures in a prescribed circular manner under push-in-place mounting of the spile. The breakout area is further constructed such that upon rupture of the frangible periphery it is pushed through and inwardly hinged so as to establish a hole having an inwardly turned periphery which functions as a biased annular lip seal that sealingly embraces the extended tubular portion of the spile. Hinging of the breakout area is facilitated by the frangible periphery being interrupted whereby a portion or the periphery is nonfrangible. The bole and the displaced breakout area remain linked by an unbroken span of plastic material that functions as a connecting hinge.
