Closure spout having tear-out portion

Abstract

A closure of injection-moulded synthetic plastic material for a bottle or other receptacle, such closure comprising a tubular body having a throat insertable into the neck of the bottle and an integral fluid-tight diaphragm across the throat with an external gripping device by which the diaphragm can be torn off, wherein the gripping device is a ring separate from the watertight diaphragm but joined to the rim of the latter by means of a base connection which is also integrally moulded. The closure has an integrally moulded pouring spout, and a replaceable cap protecting the spout.

I claim: .[.1. A molded plastic integral pouring closure for a container comprising, a tubular body comprising a throat portion insertable into the neck of the container and a skirt spaced from and outwardly of said throat portion integrally connected thereto for disposition circumferentially of the neck of the container, an extension of said throat defining a pouring spout, a sealing diaphragm transversely of said throat closing said throat portion, a tear-member connected to said diaphragm adjacent an edge thereof and disposed internally of said spout and spaced from said diaphragm, said tear-member comprising an arcuate portion for pulling thereon for tearing out the diaphragm, and means integrally connecting 
     
        said tear-member to said diaphragm..]. 2. A molded plastic integral pouring closure according to claim .[.1.]. .Iadd.6.Iaddend., including a removable protective cap mounted on said closure skirt enclosing said 
     
     
        spout. 3. A molded plastic integral pouring closure according to claim .[.1.]. .Iadd.6.Iaddend., in which said arcuate portion of said tear-member is substantially flush with an edge defining the mouth of said pouring spout. .[.4. A molded plastic integral pouring closure according 
     
     
        to claim 1, in which said tear-member comprises a split ring..]. 5. A molded plastic integral pouring closure according to claim .[.1.]. .Iadd.6.Iaddend., in which said tear-member comprises a ring. .Iadd. 6. A molded plastic integral pouring closure for a container comprising a tubular body having a throat portion insertable into the neck of a container and a skirt spaced from and outwardly concentric of said throat portion integrally connected thereto for disposition circumferentially of the neck of the container, an extension of said throat defining a pouring spout, a sealing diaphragm extending transversely across the throat opening closing same, a tear-member connected to said diaphragm adjacent an edge thereof and disposed internally of said spout, said tear-member being substantially ring-shaped and having a closed arcuate portion thereof disposed in spaced substantially parallel relation to said diaphragm so as to thereby be adapted for pulling thereon for tearing out the diaphragm, said tear-member being integrally connected to said diaphragm at at least two closely adjacent points thereof. .Iaddend. .Iadd. 7. A molded plastic integral pouring closure according to claim 6, in which said tear-member comprises a split ring, a pair of base members being integral with said diaphragm and joined to the ends of said split ring. .Iaddend..Iadd. 8. A molded plastic integral pouring closure according to claim 6, including a rupture ring member extending substantially perpendicular to the plane of said diaphragm and connecting said diaphragm to the said throat portion. .Iaddend..Iadd. 9. A molded plastic integral pouring closure according to claim 8, in which the thickness of said rupture ring is less than the thickness of said diaphragm. .Iaddend.
