Abstract
Abstract The invention provides a tubular container whose wall at at least one end is curled over to form a bead for engagement with a closure, the said curled over end portion of the container wall being of thinner gauge than the adjacent wall portion. The container can have a foil diaphragm secured across the beaded end, and may have a reusable overcap or lid engaging around the bead and closing the beaded end of the container. The beaded end of containers according to the invention is more durable than that of prior constructions, and can provide a better seat for a sealing diaphragm.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
58 words
A tubular container whose wall at at least one end is of thinner gauge than, and radially offset relative to, the adjacent wall portion, said thinner gauge wall portion being curled over through more than 270 degrees to constitute a bead occupying the area of said radial offset and projecting radially therefrom for sliding engagement with a closure.
Claim 2
Dependent Claim
58 words
A tubular container whose wall at at least one end is of thinner gauge than, and radially offset relative to, the adjacent wall portion, said thinner gauge wall portion being curled over through more than 270 degrees to constitute a bead occupying the area of said radial offset and projecting radially therefrom for sliding engagement with a closure.
Claim 3
Dependent Claim
21 words
A tubular container according to claim 1 wherein the said end wall portion of thinner gauge is one made by pressure-grooving.
Claim 4
Dependent Claim
35 words
