Abstract
Abstract A container is disclosed having a collapsible pouring spout in the top portion thereof. The pouring spout is nestable within the container in a preferred arrangement, and the container walls, container top and pouring spout are of integral or unitary construction having been blow molded. The pouring spout in the nested position within the container is more easily withdrawn if a vent is provided. The vent may be opened at the time it is desirable to initially withdraw the spout for dispensing from the container. Where the spout has a removable cover secured thereto in unitary fashion with a weakened tear line therearound, and the cover has a handle means thereon for withdrawal of the spout and removal of the cover, the present invention adds a further feature of a V or similar shaped undercut adjacent the weakened tear line between the cover and the pouring spout. Upon lifting of the cover handle, the V shaped undercut section opens first and accomplishes a double result. A vent is produced for the pouring spout for easy withdrawal from the container body, and secondly, the undercut section is the beginning of the tear line for removal of the cover whereby the cover can be pulled from the container spout by further lifting of the handle.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
148 words
An improved dispensing container comprising: a. a container body; b. a top secured to said body; c. a pouring spout secured to said top, said spout being nestable within said body and withdrawable to an extended, dispensing position; d. a cover secured to said pouring spout and including spout withdrawal means thereon, said cover being removeable from said spout to permit dispensing of the contents of said container therethrough; and e. vent forming means located on said spout and being secured to an underside of a portion of said cover, said vent forming means comprising a strip of meterial extending from beneath said cover along a portion of the length of said spout, said material having an undercut portion therealong to foster rupture upon receipt of sufficient force thereon to produce said vent in said spout and permit ease of withdrawal of said spout from a vested position.
