  • Patent number: 6158305
    Abstract: A bottle cap remover used to separate a cap from a bottle wherein the cap has an upper section and a lower section, and at least a portion of the upper section of the cap protrudes radially outwardly beyond the lower section of the cap. The cap remover includes a first grip member and a second grip member. The first grip member is rigidly mounted to a stop plate in a position where the first grip member is spaced from the stop plate to define a gap between the first grip member and the stop plate. The first grip member includes a cap engaging edge which at least partially corresponds to an outside surface of the cap. The second grip member is positioned in opposed relationship to the first grip member and has a grip surface positioned a predetermined distance from the cap engaging edge of the first grip member.

  • Patent number: 5313858
    Abstract: A device for removing a rubber stopper from a test tube is mountable to an upright wall, has a generally horizontal splash guard, and a lower plate spaced parallel to and below the splash guard. A slot in the lower plate has spaced-apart opposing edges that converge towards each other from the plate outer edge to a narrowed portion, the opposing edges shaped to make engagement between the bottom of the stopper flange and the top edge of the test tube to wedge therebetween and to grasp the stopper in the slot narrowed portion to hold the stopper as the test tube is manipulated downwardly and pulled from the stopper. The opposing edges extend inwardly to adjoin an opening having a diameter significantly larger than that of the stopper flange.

  • Patent number: 5052251
    Abstract: Improved locking wrenches are provided with adjustment screws having a head portion which defines at least one opening registerable with an aperture defined in an extension member rearwardly extending from the lower handle of the wrench. In this manner, a restraining element may be placed through the registered opening/aperture to positionally restrain (immobilize) the upper and lower wrench handles relative to one another. The head of the adjustment screw and/or the extension member according to the present invention may be embodied in a number of alternative arrangements to provide the necessary cooperative relationship as between the opening and aperture respectively defined thereby.

  • Patent number: 4873896
    Abstract: The opener comprises a base which is attached to support structure and provides a member extending generally horizontal and a lift tab engagement element hinged to the end of the generally horizontal base member. The engagement fits over the rim of the top of a lift tab container and under the tab, extending somewhat past the effective hinge point of the tab on the container top and positioned laterally with respect to the lift tab by a flange on each side of the element. A tab extends from each flange part way over the top of the lift tab. The engagement element is hinged so that it can deflect downward only from its essentially horizontal at rest position and is returned to that position by a spring. In use the container is maneuvered to engage the lift tab in the engagement element and then moved so that the engagement element pivots on its hinge axis, functions as a Class 2 lever and opens the container. Reversing the opening motion puts the lift tab into close to its original position.

  • Patent number: 4774859
    Abstract: An opener for a tab-top container has a base adapted to be mounted to a supporting surface. Opposing camming surfaces convergently extend from the base to a juncture. An initiating edge formed at the juncture is used to be positioned under the edge of a tab so that when the container is pushed generally toward the base, the tab is cammed away from the end wall causing the closure to responsively open. A method suggested by use of the tab opener is disclosed.

  • Patent number: 4712454
    Abstract: The subject device comprises two cams structurally supported from a base attachable to a vertical surface. The cams are positioned to interact with the lift-tabs of lift-tab containers as the container is in a vertical position and moved first toward the device and then from it. As the container is moved toward the opener, one cam engages the lift-tab and lifts it to open the container. As the container is moved away from the opener, the other cam depresses the lift tab to approximately its position before the can was opened. The cams are positioned one behind the other in a line perpendicular to the vertical surface. The tab lifting cam extends below the tab depressing cam and is the closer of the two to the base. The end of the lift tab moves below the end of the depressing cam as the container is moved into the opener and raised by the lifting cam. The lifted tab is then engaged and depressed by the depressing cam as the container is moved away from the opener.

  • Patent number: 4663994
    Abstract: A formed, or molded, wall mounted bracket which extends horizontally from a mounting surface and serves to "one-handedly" raise a lift-tab on beverage cans and others, so equipped, by placing the upper surface of the above mentioned cans beneath a downward projecting nose at the individual's end of said bracket and pushing the container in one smooth motion toward the bracket, thus causing the downward facing projection to wedge the lift-tab upward and through an arc of nearly 100.degree. and, further causing the lift-tab to break the container's seal which, in turn allows the individual access to the contents within.
