Reservoir module for pump dispenser

A fluid dispenser, comprising:

• a dispenser body enclosing an interior,
• a bulkhead disposed in the dispenser body, dividing the interior into an upper chamber and a lower chamber,
• a hollow spike attached to the bulkhead, the hollow spike enclosing a through hole,
• a fluid reservoir module comprising:
• a base,
• a reservoir body enclosing an hermetically sealed internal void, the reservoir body having a top portion and a bottom portion, wherein the reservoir body is disposed on the base and the bottom portion is connected to the base, and
• a removable tab attached to the reservoir body, wherein the removable tab blocks inserting the reservoir body into the lower chamber, and removal of the removable tab allows the insertion of the reservoir body into the lower chamber.

A fluid dispenser, comprising:

• a dispenser body enclosing an interior, the dispenser body having blocking tips, wherein there are retaining beads attached to an interior surface of the dispenser body;
• a bulkhead disposed in the dispenser body, dividing the interior into an upper chamber and a lower chamber;
• a hollow spike attached to the bulkhead, the hollow spike enclosing a through hole and a second hole;
• and
• a fluid reservoir module comprising:
• a base,
• ribs attached to the base,
• a reservoir body hermetically sealing an internal void, the reservoir body having a top portion and a bottom portion, wherein the ribs have profiled inner forms, the bottom portion of the reservoir body has profiled surfaces, and the profiled inner forms match the profiled surfaces, allowing the reservoir body to fit to the ribs, the top portion of the reservoir body comprises an upper neck encircling a neck hole, the neck hole being sealed by a frangible membrane,
• two removable tabs attached to the reservoir body, wherein the removable tabs have notches that engage the blocking tips, blocking inserting the reservoir body into the lower chamber, and removal of the removable tabs allows the insertion of the reservoir body into the lower chamber,
• a snapping tongue attached to the base, wherein inserting the reservoir body into the lower chamber pushes the snapping tongue to engage a tongue receiver in the dispenser body, and
• a projecting arm attached to the top portion of the reservoir body, the projection arm partially extending into the lower chamber,
• wherein the retaining beads engage the projecting arm and restrict the projecting arm to slide between the retaining beads.
