Patent number: 6158305Abstract: 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.Type: GrantFiled: October 20, 1998Date of Patent: December 12, 2000Assignee: Blackhawk Molding Co., Inc.Inventor: Frank J.

Patent number: 5313858Abstract: 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.Type: GrantFiled: March 8, 1993Date of Patent: May 24, 1994Assignee: Midwest Research InstituteInventor: Robert R. Stitt

Patent number: 5265501Abstract: An improved bottle cap opener is provided which consists of a housing having an open top and an open bottom. A mechanism is for mounting the housing to a flat vertical surface. A structure at the open top of the housing is for removing a cap from a bottle. A device at the open bottom of the housing is for catching the cap after it is removed from the bottle, so as to keep the area about the opener clean, while caps can be collected for possible recycling.Type: GrantFiled: April 6, 1992Date of Patent: November 30, 1993Inventor: Gilbert Reyes

Patent number: 5107728Abstract: Apparatus for opening lift tab containers. The apparatus comprises a lifting tongue and a side engaging positioner. The lifting tongue is adapted to engage and lift a lift tab on the container and the side engaging positioner is adapted to use the sides of the container to ensure the proper positioning of the container with respect to the lifting tongue. The opening apparatus can comprise a cavity having a drain for draining liquid from the cavity.Type: GrantFiled: August 6, 1990Date of Patent: April 28, 1992Inventor: Dennis T. Siekierke

Patent number: 5052251Abstract: 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.Type: GrantFiled: September 18, 1990Date of Patent: October 1, 1991Assignee: Blue Water Holding Company, Inc.Inventor: J. David Mills

Patent number: 4873896Abstract: 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.Type: GrantFiled: December 12, 1988Date of Patent: October 17, 1989Inventor: Alan Hull

Patent number: 4774859Abstract: 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.Type: GrantFiled: December 10, 1987Date of Patent: October 4, 1988Inventor: Darcey L. Jarvis, Sr.

Patent number: 4712454Abstract: 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.Type: GrantFiled: August 18, 1986Date of Patent: December 15, 1987Inventors: Alan Hull, Michael J. Yates

Patent number: 4663994Abstract: 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.Type: GrantFiled: February 12, 1986Date of Patent: May 12, 1987Inventor: Alan Hull
