  • Patent number: 4073205
    Abstract: The invention is a container opener for child resistant containers. The container opener comprises a body having a notch and friction means on the notch surface such as triangular shaped pointed teeth, or a plurality of protrusions extending into the notch, and a blade. An alignment wall facilitates aligning a cover of the container to the friction means. The cover of the container is inserted into the notch and the cover is pressed against the friction means and the container opener is then rotated to align the cover of the container so that the cover will unlock from the receptacle of the container. The cover of the container is removed by inserting and twisting the blade between the cover and the receptacle of the container.

  • Patent number: 4067279
    Abstract: A device for manually crimping metal caps of the type commonly used for medical solution bottles. The crimper takes the form of a generally cylindrical body dimensioned to be held in the hand and defining a cavity open at its bottom and along a portion of its side to receive the neck of a bottle upon which an uncrimped metal cap has been placed. A shoulder within the cavity bears against the skirt of the cap and, as the crimper is rotated relative to the bottle, the bottom of the skirt is turned inwardly to secure the protective cap upon the bottle neck.

  • Patent number: 4001904
    Abstract: A kitchen utensil molded of rubber or flexible synthetic plastic which has a centrally disposed, stepped, hollow frustro-conical jar cap remover that is readily gripped in the palm of the hand, surrounded by a radially disposed, planar flange, the surface of which on the side of the hollow is roughened or otherwise formed for soft abrasive action. The stepped frusto-conical portion can receive different size jar caps and has axially disposed ribs on the cylindrical walls of the step portions for frictionally engaging the rim of a jar cap to facilitate its removal. The frustro-conical portions are capable of nesting with each other in spaced relation so that a plurality of the devices may be gripped and handled simultaneously. In this manner, the utensil may be used as a pot holder with the conical portions preventing slippage between a plurality of the devices and also providing air spaces between the devices for insulating purposes.
