  • Patent number: 11697531
    Abstract: A dispensing lid includes a port through the lid, a slider in sliding engagement with the lid, and a detent on the slider. The slider is selectively movable between a closed position that closes the port, an open position that opens the port, and removal from the lid. The detent includes a wall extending from the slider, a lever attached to the slider at a pivot, a pawl extending from the lever, and a catch extending from the pawl. The lever is in an orientation opposing the wall with a gap between the lever and the wall. The catch engages a first stop in the lid when the slider is in the closed position with the lever released, engages a second stop in the lid when the slider is in the open position with the lever released, and does not engage the lid when the slider is removed.

  • Patent number: 6212721
    Abstract: A combined bottle opener and stopper comprises a metal plate with side edges bent downward and inwardly. Opening is performed with the use of a conventional pry off method. Opened bottles are closed with a rubber pad attached to the bottom of a recess on the inner face of the plate. The opener-stopper has three bent edges which have different heights with the difference corresponding to the pitch of the thread on a threaded bottle neck. For temporary closing the bottle, i.e., with beer or carbonated water, the device is screwed onto the threaded bottle neck as a nut until the rubber pad is tightly pressed to the upper face of the bottle to hermetically close the latter. For closing bottles with nonthreaded bottle necks, the device is moved onto the bottle neck by guiding the convergent bent edges over the neck in a direction transverse to the bottle's axis until the device is fixed tightly on the bottle due to convergence of the bent edges with the rubber pad, thereby to seal the bottle's opening.

The container body has a lead case formed therein, and a lead outlet allowing release of leads one by one. A gate member mounted in the container body can be moved to open or close lead paths between the lead case and lead outlet. An elastic arm portion forces the gate member to move in direction to close the lead paths. The number of parts is reduced, and supplying leads can be made easier by a case that has a lead supply opening projecting from the tip thereof. A leading end of the case has an inclined slope toward the lead supply opening therein, and a chuck containing leads having a knocking portion that is pressed into the case so that it can be opened by the knocking portion being pushed to press an opening actuator toward the inclined slope or is closed by an elastic force as the opening actuator is released.

  • Patent number: 5687885
    Abstract: A dispensing container, such as a double-barrel cartridge used in dispensing dental material, matingly receives a sliding cap that maintains a seal between material in the barrels and the atmosphere. The cap includes a body and a gasket within the body, and the cap also includes a cam portion that shifts the body slightly away from an outlet of the container as the cap is moved toward a closed position to seal the container. Once the cap is in a fully closed position, the cam portion enables the body to shift somewhat closer to the container outlet in order to increase the compression of the gasket between the body and the outlet. Optionally, an orienting section is provided for insuring that the cap is coupled to the container in only one certain orientation, so that the likelihood of cross-contamination of material within the barrels due to residual material on the gasket is substantially reduced.
