ABSTRACT:
A venting type container to relieve pressurized carbonated liquids and the like without discharging the liquid therefrom while equalizing the interior container pressure with atmospheric pressure including in combination a flexible wall container for receiving the liquid and adapted to operatively receive a removable dispensing cap assembly which when brought into full threaded engagement with said dispensing cap assembly redefines the opening to said container; and a depressurization sealing unit which is operatively received on the dispensing cap assembly in sealing engagement to seal and contain the liquid within the container and define an interior cavity oriented between the dispensing cap assembly and the depressurization sealing unit. When the sealing relationship between the dispensing cap assembly and the depressurization sealing unit is initially broken a vent passage is defined which prevents the nongaseous contents of the container from escaping, but allows the gaseous contents to pass through vent holes and into the containment cavity between the dispensing cap assembly and the depressurization sealing assembly. Upon full removal of the depressurization sealing assembly the vent holes bring the interior of the container in continuous communication with the atmospheric pressure thereby preventing the collapse of the flexible wall container as liquid is extracted therefrom.
