Container top with integral stopper

Claim 1

A top for a container having a corrugated side wall and an open neck comprising: a funnel-shaped body of a moldable material, said body having a top opening, a passage therethrough centrally disposed at the bottom thereof, and means thereon for coupling the body to the neck of the container with the passage communicating with the container, the body having an inner surface provided with a downward slope extending throughout a major part of the distance between said top opening and the passage and terminating at the passage; and an elongated stopper having a tapered outer surface and being of said material, said stopper being integral at one end thereof with the body at the termination of said inner surface, in alignment with said passage, and extending upwardly therefrom with the upper end of the stopper being adjacent to and below said top opening, there being a line of weakness at the junction between the body and the stopper to permit the latter to be separated from the body when the stopper is shifted relative to the body, the stopper having a maximum transverse dimension greater than that of the passage, whereby the stopper, after being separated from the body, can be inverted and inserted into the passage to at least partially close the same.
