a head skirt;

a closure for attaching the dispenser to the container; and

a tamper evident nozzle shield attached to the dispenser, the tamper evident nozzle shield comprising:

a dust cap;

a connector connected to the dust cap;

a tamper evident structure opposite the dust cap and removably connected to the connector by at least one breakpoint;

a collar attached to the connector; and

2. The fluid dispenser of claim 1 , wherein the dust cap is configured to cover at least a portion of the nozzle.

3. The fluid dispenser of claim 1 , wherein the tamper evident structure further comprises a pull-tab.

4. The fluid dispenser of claim 1 , wherein the tamper evident structure further comprises a pull-tab configured to tear away from the connector along the at least one breakpoint when sufficient force is applied to the tamper evident structure.
