Abstract
An improved imbibing agent dispenser having a snap-on closure which is highly reliable, is simple to assemble on one end of the agent dispenser, and can be made at minimum expense without requiring heat or an adhesive to bond the closure to the dispenser. The closure is held in place on the dispenser by a locking feature formed by a shoulder on the end of the dispenser and a ledge on an outer, annular wall of the closure, the ledge being removably hooked beneath and biased toward the shoulder to releasably lock the closure to the dispenser. An important aspect of this closure is that the design provides for the complete containment of a solute component within the dispenser.
