There is shown a dispensing apparatus for use with pressurized containers of fluids, particularly carbonated beverages such as beer. A base that fits onto the container has a piston member slidably fitted to it, along with a compressed gas housing and a pickup tube or assembly. A handle moves the piston member with respect to the base against a spring bias. A gas flow path from the housing to the container passes through a valve, that is opened by the piston member as the handle is moved. Moving the handle opens both a liquid flow path as well as a gas f...

1. A dispenser apparatus for attachment to a beverage container having an interior for containing a beverage, comprising: a base having an opening for communicating with the interior of the beverage container when attached to the beverage container, and a lateral channel;a piston member slidably within the lateral channel, the piston member having a spout portion outside of the channel and moveable with the piston member, and a conduit extending through a wall of the piston member and out of the spout portion whereby beverage from within the container may pass through the conduit and exit from the spout portion;a handle pivotally attached to the base, the handle connected to the piston member so that as the handle is pivoted toward the base, the piston member is forced through the lateral channel of the base;a compressed gas housing attached to the base, the housing including an inner cavity;wherein a flow path extends from the cavity of the compressed gas housing through the base to the opening, the flow path having multiple constricting points, including a first constricting point including a chamber having a restrictor plug at least partially in the chamber, and a second constricting point including a valve. 2. The apparatus of claim 1, wherein the flow path includes a third constricting point including a conduit from the lateral channel to the opening, the conduit being narrower than the chamber of the first constricting point. 3. The apparatus of claim 1, wherein the lateral channel is non-parallel with the restrictor plug. 4. The apparatus of claim 1, wherein the piston member includes an end opposite the spout portion with an end opening facing the valve, and a spring engaging the piston member within the end opening and engaging a sleeve holding the valve. 5. The apparatus of claim 4, wherein the piston member includes a threaded gap communicating with the end opening and the valve includes a pin biased to a closed position, and further including a screw threaded in the gap, the screw contacting the pin at a point when the handle is pivoted a predetermined amount toward the base, whereby the screw moves the pin to open the valve. 6. The apparatus of claim 1, wherein the apparatus has a first idle configuration and a second dispensing configuration, and in the first configuration the handle is positioned with respect to the compressed gas housing so that an adult can grasp the compressed gas housing and the handle at the same time with a single hand. 7. The apparatus of claim 6, wherein the second configuration is attained by pivoting the handle toward the compressed gas housing. 8. The apparatus of claim 1, wherein the compressed gas housing includes a compressed gas tube having an outlet and a cap, and wherein in operation the outlet of the compressed gas tube faces the cap. 9. The apparatus of claim 1, further comprising a feed tube removably fixed to the base and extending through the opening to extend into the beverage container. 10. A system for dispensing beverage under pressure from a container, comprising: a base for attachment to the container, the base having a gas flow path including a valve;a piston member slidably within the base, having a spout portion extending away from the base and moveable with the piston member, and a fluid flow channel;a handle pivotally attached to the base, wherein the handle can engage the piston member to move the piston member into the base and toward the valve;a compressed gas housing attached to the base; anda pickup assembly extending from the body and for extending into the container,wherein moving the piston member into the base a desired amount causes a portion of the piston member to engage a portion of the valve to open the valve and allow gas to move through the valve. 11. The system of claim 10, wherein the gas flow path comprises a narrow outlet between the compressed gas housing and the valve forming a first constricting point, and wherein the valve is a second constricting point in the gas flow path. 12. The system of claim 11, further comprising a plug having a longitudinal groove engaged in the base, the longitudinal groove forming at least part of the narrow outlet. 13. A dispenser apparatus for attachment to a beverage container having an interior for containing a beverage, comprising: a base having an opening for communicating with the interior of the beverage container when attached to the beverage container and a lateral channel spaced from the opening;a valve attached to the base within the lateral channel and along a gas flow path through the base;a piston having a spout portion, moveable with the piston the piston being at least partially within the lateral channel and the spout portion having a tip outside of the lateral channel, and the piston being movable along the lateral channel toward and away from the valve,wherein the gas flow path extends from an upper cavity in the base for accommodating a gas source to the opening, the gas flow path having a plurality of constricting points, including a first constricting point including a narrow outlet between the upper cavity and the valve, and wherein the valve is a second constricting point. 14. The apparatus of claim 13, further comprising a plug having a longitudinal groove engaged in the base, the longitudinal groove forming at least part of the narrow outlet. 15. A dispenser apparatus for attachment to a beverage container having an interior for containing a beverage, comprising: a base having an opening for communicating with the interior of the beverage container when attached to the beverage container, and a channel;a piston member slidably within the channel, the piston member having a spout portion outside of the channel and moveable with the piston member, and a conduit extending through a wall of the piston member and out of the spout portion whereby beverage from within the container may pass through the conduit and exit from the spout portion, the piston member including an end opposite the spout portion with an end opening facing the valve, and a spring engaging the piston member within the end opening;a handle pivotally attached to the base, the handle connected to the piston member so that as the handle is pivoted toward the base, the piston member is forced through the channel of the base; anda compressed gas housing attached to the base, the housing including an inner cavity. 16. The apparatus of claim 15, wherein the piston member includes a threaded gap communicating with the end opening and the valve includes a pin biased to a closed position, and further including a screw threaded in the gap, the screw contacting the pin at a point when the handle is pivoted a predetermined amount toward the base, whereby the screw moves the pin to open the valve. 17. The apparatus of claim 15, wherein the spring also engages a sleeve holding the valve. 18. The apparatus of claim 13, further comprising a handle for moving the piston toward the valve, the handle having an outer surface facing away from the body and including a slot through which a part of the piston extends beyond the outer surface. 19. The apparatus of claim 13, wherein the piston includes at least one rounded shoulder facing the handle to the side of the spout portion, and wherein the handle engages the at least one rounded shoulder portion so as to move the piston toward the valve. 20. The apparatus of claim 1, wherein the compressed gas housing includes a tube having first and second ends and a cap, the tube connected to the body at the first tube end and to the cap at the second tube end opposite the body, the cap having a pierce pin.
