A method of manufacturing a container containing propellant includesi) sealing a first sheet of rupturable material to a second sheet of rupturable material to form a lower seal and two side seals;ii) placing a propellant dispensing apparatus in fluid communication with a central volume defined by said lower seal, the two side seals and a seal between the propellant dispensing apparatus and the first and second sheets;iii) depositing propellant in the central volume using the propellant dispensing apparatus; andiv) sealing the first sheet to the second sheet to form an upper seal to form a container where the propellant is contained between the upper seal, the lower seal, and the two side seals.
