A device comprising:
- a base,
- a post connected to said base,
- a slide track connected to said post,
- a slide member in sliding engagement of said slide track,
- a bracket extending from said slide member away from said post,
- a lever connected to said post and said bracket,
- a bar connecting the free ends of said bracket and connecting said lever to said bracket,
- a cylindrical member depending from said bar, said cylindrical member having a closed bottom with a bottom surface and a pair of V-shaped slots on opposing sides of said outer shaft through which said bar passes,
- a spring located between said bar and said closed bottom of said cylindrical member, and
- a selector sleeve on the inside of said cylindrical member and around said spring, said selector sleeve having
- a pair of cover members on opposing sides and
- a member extending from the sleeve, said extending member abuts said cylindrical member.
A device for use in loosening and tightening lids onto containers, the device comprising:
- a base,
- a support member connected to said base,
- a lever in communication with said support member, and
- means for converting movement of said lever into downward pressure on a container lid prior to rotating the lid with direction of rotation selected by the user.
An apparatus for fastening and unfastening twist cap containers, comprising:
- a base,
- an upright member attached to said base,
- a lever attached to said upright member,
- a rotating member attached to said upright member and said lever, said rotating member in response to downward movement of said lever applies a rotating force on the container such that the twist cap is fastened or unfastened and;
- a selector attached to said rotating member, wherein the position of said selector determines the direction of rotation of said rotating member.
