ABSTRACT:
An inlet is adapted to receive pressurized gas from a CO2gas cartridge. A variable compression member has a normal height, under normal operating temperature conditions, adapted to provide a normal compressive force between the gas cartridge and the inlet to effectively seal the gas cartridge to the inlet. The variable compression member also has a reduced height, under heightened temperature conditions, adapted to provide a reduced compressive force between the gas cartridge and the inlet to allow pressurized gas to escape between the gas cartridge and the inlet. A seal member is compressed between the gas cartridge and the inlet. The inlet may be part of a pneumatic dispensing device. The gas inlet is in fluid communication with a gas enclosure to enable pressurized gas delivered through the inlet to provide a dispensing force on a product cartridge to cause dispensing of the viscous product.
