Fluid dispensing method and apparatus

A fluid storage system comprising:

• a container defining an interior space that lacks an internal valve;
• a product and a propellant stored under pressure within the interior space;
• and
• a container cap coupled to the container to enclose the container and maintain the product and the propellant within the interior space of the container, the container cap comprising:
• a coupling element that defines a fluid passage bore, the coupling element comprises an externally threaded section,
• a collar,
• a well disposed between the coupling element and the collar, defining a downward-opening, annual channel,
• a membrane enclosing a first end of the fluid passage bore defined by the coupling element that seals the product and the propellant within the interior space of the container,
• the externally threaded section engages a compatible fastener provided to a reusable dispensing apparatus to releasably couple the reusable dispensing apparatus to the container cap wherein the membrane is pierced by a portion of the reusable dispensing apparatus when the reusable dispensing apparatus is installed on the container cap to establish fluid communication between the interior space and the reusable dispensing apparatus and establish a seal that interferes with an escape of the propellant between the container cap and the reusable dispensing apparatus after the membrane has been pierced, and
• a dip tube comprising a proximate end arranged adjacent to the fluid passage bore defined by the coupling element, and a distal end that protrudes in a direction away from the container cap, into the interior space defined by the container, wherein the dip tube defines an interior passage extending between the proximate end and the distal end through which the product is to travel to be expelled from the container through the container cap and the reusable dispensing apparatus by the propellant.
