Abstract

Abstract There is disclosed a device for releasing closure members from containers. The device has a frustoconical-shaped body member of a relatively rigid material which has a frustoconical-shaped recess therein. Within the recess is located a frustoconicalshaped gripping member of a resilient material, which is open ended at its larger end and able to engage a closure member. The body member and gripping member are restrained from relative movement, and by engaging the gripping member on the outside of a closure member, a person may apply torque to the body member and thus to the closure member. Thus by imparting relative angular displacement between the container and its closure member, the closure member may be removed from the container.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 132 words
A closure gripping device for use in imparting relative angular displacement between a container and a closure therefore comprising: a body member of relatively rigid material having a recess therein, a hollow gripping member of resilient material contained within the recess in the body member and nonrotatable relative thereto in at least one direction, said gripping member including a first part having a generally frustoconical interior and open ended at its larger end and adapted to be engaged with the outside of a closure member, said gripping member including a second part in the form of a tapered sleeve being removably engageable against the inside surface of said first part, whereby said second part can be inserted or removed to increase the range of diameters over which the device can be used.
Claim 2
Dependent Claim 132 words
A closure gripping device for use in imparting relative angular displacement between a container and a closure therefore comprising: a body member of relatively rigid material having a recess therein, a hollow gripping member of resilient material contained within the recess in the body member and nonrotatable relative thereto in at least one direction, said gripping member including a first part having a generally frustoconical interior and open ended at its larger end and adapted to be engaged with the outside of a closure member, said gripping member including a second part in the form of a tapered sleeve being removably engageable against the inside surface of said first part, whereby said second part can be inserted or removed to increase the range of diameters over which the device can be used.
Claim 3
Dependent Claim 43 words
The device, as set forth in claim 1, wherein said first part of said gripping member has an outer surface which is complementary to the inner surface of said body member and an inner surface provided with a series of grooves or flutings.
Claim 4
Dependent Claim 33 words
The device, as set forth in claim 2, wherein said grooves or flutings are tapered and are widest at said open larger end of said first part, and narrowing towards its other end.
Claim 5
Dependent Claim 62 words
The device, as set forth in claim 2, wherein said second part of said gripping member has an outer surface which is complementary to the inner surface of the said first part, said outer surface of the second part having longitudinal ribs which are complementary to said grooves or flutings on said inner surface of said first part of said gripping member.
Claim 6
Dependent Claim 37 words
The device, as set forth in claim 4, wherein said longitudinal ribs on said outer surface of said second part are tapered and fit into said grooves or flutings of said first part of the gripping member.
Claim 7
Dependent Claim 44 words
The device, as set forth in claim 2, wherein said second part of said gripping member has a series of grooves or flutings on its inner surface which are narrower than those on said inner surface of said first part of said gripping member.
