  • Patent number: 5207339
    Abstract: A bottle cap assembly it is described which includes a hollow cylindrical body adapted to be fastened to the neck of a soda water bottle to seal the top opening thereof, a valve seat having valves to seal an outlet hole on the hollow cylindrical body, a division plate to hold said valve seat in place, a cap retained on said hollow cylindrical body and a bellows within said body retained by the cap. The device functions when the cap is pressed which causes outside air to be compressed and fed into the soda water container to pressurize the same. A release of the cap causes an expansion of the bellows which readmits outside air into the bellows without releasing the contents of the soda water bottle.

  • Patent number: 5145094
    Abstract: A liquid dispensing closure mechanism installable on the neck portion of a plastic squeeze bottle to control the outflow of liquid from the bottle. In one form of the dispensing closure, a movable closure body has an open position and a closed position in which closed position the closure body fits tightly on the associated cap member. In another form of the dispensing closure, the movable closure body has two closed positions, in one of which the closure body fits tightly on the associated cap member, and in the other of which it fits loosely on the cap member, whereby it is readily movable to the open position with only slight manual effort. A twist lock feature is preferably utilized where a gas-tight seal is of major importance for containment of carbonated beverages.

The single-service coupling and valve assembly is comprised of two main parts, namely, a spout fitment for a flexible bag and a valve member which slidably fits within the spout for axial movement. The valve member is provided with an outwardly-opening socket for receiving the connector and this socket has at least one dispensing outlet in the base thereof. In use, the valve member is normally in closed position with the outlet disposed within the spout axially-outwardly of an inner seal between the spout and valve member. A one-way stop arrangement permits axial inward movement of the valve member relative to the spout but prevents axial outward movement, the inward movement opening the valve by moving the outlet inwardly beyond the spout.
