replacing the cap 114 and protruding from the container 102 the amount of air or fluid pumped through the valve 110 into the annular space 116 is increased to raise the pressure on the bladder 104 sufficiently to force the carbonated beverage 112 up the siphon 220 the siphon 220 can have a dispensing valve 222 connected at the protruding end of the siphon 220 for regulating the of carbonated beverage 112 from the bottle 100 the siphon 220 can also have a beveled distal end 224 thereby helping to avoid blockage by the collapsing bladder 104 the bottle 100 is refilled with carbonated beverage by either first unfastening the cap 114 from the bottle 100 and removing the cap 114 and siphon 220 contemporaneously or by first removing the siphon 220 prior to unfastening the cap 114 the bottle can be used for other liquids as well as for carbonated beverages for example using the siphon system the bottle can be used to pressurize any liquid for convenient and optionally metered dispensing replacing bulkier larger volume containers that rely on heavy mechanical pumps the foregoing description of preferred embodiments of the present invention has been provided for the purposes of illustration and description it is not intended to be exhaustive or to limit the invention to the precise forms disclosed many modifications and variations will be apparent to one of ordinary skill in the.
