Abstract

Abstract The present invention relates to an improvement of a container closure comprising a container provided with an open-topped cylindrical neck member and a cap member provided with a skirt portion and removably mounted on the neck member. A plurality of circumferentially spaced annular grooves are provided in either the outer wall of the neck member or the inner wall of the cap member, and a plurality of projections receivable in the grooves are formed on the other of these walls. At least one of the cap member and the container is made of relatively elastic material.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 127 words
In combination, a container and a container closure, the container including a generally cylindrical open neck portion having an outer wall, the outer wall being provided with a plurality of circumferentially spaced arcuately extending annular grooves, the container closure comprising a top cap portion and a downwardly extending generally cylindrical skirt portion having an inner wall, the inner wall including a plurality of circumferentially spaced radially inwardly extending projections receivable in the annular grooves whereby the container closure may be removably secured to the neck portion by inserting the projections into the annular grooves and may be removed by rotating the container closure relative to the neck portion to bring the projections into engagement with the portions of the outer wall of the neck between the grooves.
Claim 2
Dependent Claim 127 words
In combination, a container and a container closure, the container including a generally cylindrical open neck portion having an outer wall, the outer wall being provided with a plurality of circumferentially spaced arcuately extending annular grooves, the container closure comprising a top cap portion and a downwardly extending generally cylindrical skirt portion having an inner wall, the inner wall including a plurality of circumferentially spaced radially inwardly extending projections receivable in the annular grooves whereby the container closure may be removably secured to the neck portion by inserting the projections into the annular grooves and may be removed by rotating the container closure relative to the neck portion to bring the projections into engagement with the portions of the outer wall of the neck between the grooves.
Claim 3
Dependent Claim 24 words
The structure of claim 1 in which the container is formed of relatively rigid material and the cap is formed of relatively elastic material.
Claim 4
Dependent Claim 129 words
In combination, a container and a container closure, the container closure comprising a top cap portion and a downwardly extending generally cylindrical skirt portion having an inner wall, the inner wall being provided with a plurality of circumferentially spaced arcuately extending annular grooves therein, the container including a generally cylindrical open neck portion having an outer wall, the outer wall including a plurality of circumferentially spaced radially outwardly extending projections receivable in the annular grooves whereby the container closure may be removably secured to the neck portion by inserting the projections into the annular grooves and may be removed by rotating the container closure relative to the neck portion to bring the projections into engagement with the portions of the inner wall of the skirt portion between the grooves.
Claim 5
Dependent Claim 129 words
In combination, a container and a container closure, the container closure comprising a top cap portion and a downwardly extending generally cylindrical skirt portion having an inner wall, the inner wall being provided with a plurality of circumferentially spaced arcuately extending annular grooves therein, the container including a generally cylindrical open neck portion having an outer wall, the outer wall including a plurality of circumferentially spaced radially outwardly extending projections receivable in the annular grooves whereby the container closure may be removably secured to the neck portion by inserting the projections into the annular grooves and may be removed by rotating the container closure relative to the neck portion to bring the projections into engagement with the portions of the inner wall of the skirt portion between the grooves.
Claim 6
Dependent Claim 24 words
The structure of claim 3 in which the container is formed of relatively rigid material and the cap is formed of relatively elastic material.
