Abstract
Abstract In a combined container and lid the lid is provided with an inverted approximately U-shaped edge defining a lid wall which, when the lid is mounted on the container, projects into a flanged end of the container. The lid has a skirt which surrounds the container end and is provided with means for tightening and/or clamping it at least at the free edge of the skirt in order to reduce the circumferential length of the skirt edge, so that when the lid is pressed onto the container end it simultaneously compresses said flanged end to provide a sealing closure in the U-shaped edge of the lid.

Claim 3
Dependent Claim
194 words
an approximately U-shaped lid having a. wall projecting into the upper end wall of the container and radially reinforcing the upper end wall, b. an edge ring radially outwardly extending from the lid wall, and c. a skirt extending downwardly from the periphery of the edge ring and having an edge at the end thereof, the lid edge ring and skirt defining a groove with the upper end wall of the container, and the groove receiving the peripheral edge of the container: the improvement which comprises in combination a clip-shaped skirt edge having at least one circumferentially disposed slot disposed therein, wedge-type sides projecting from the skirt edge and projecting outwardly from beneath said slot, and a partially extended skirt edge disposed onto said wedge-type sides and integral therewith for elastically radially inwardly tensioning the skirt edge and thereby to press the skirt edge against the upper end wall of the container, the tensioned skirt edge causing the skirt sealingly to enclose the peripheral edge of the container and to hold the peripheral edge firmly in position in the groove between the upper end wall of the container and the skirt of the lid.
Claim 4
Dependent Claim
194 words
an approximately U-shaped lid having a. wall projecting into the upper end wall of the container and radially reinforcing the upper end wall, b. an edge ring radially outwardly extending from the lid wall, and c. a skirt extending downwardly from the periphery of the edge ring and having an edge at the end thereof, the lid edge ring and skirt defining a groove with the upper end wall of the container, and the groove receiving the peripheral edge of the container: the improvement which comprises in combination a clip-shaped skirt edge having at least one circumferentially disposed slot disposed therein, wedge-type sides projecting from the skirt edge and projecting outwardly from beneath said slot, and a partially extended skirt edge disposed onto said wedge-type sides and integral therewith for elastically radially inwardly tensioning the skirt edge and thereby to press the skirt edge against the upper end wall of the container, the tensioned skirt edge causing the skirt sealingly to enclose the peripheral edge of the container and to hold the peripheral edge firmly in position in the groove between the upper end wall of the container and the skirt of the lid.
