Applicators for storing, sterilizing, and dispensing adhesives. The applicators comprise a porous tip, a body, and a container containing a polymerizable cyanoacrylate monomer adhesive. The applicators are sterilized by radiation, and following sterilization, the adhesive remains substantially unpolymerized for about twenty four months.

A dispenser actuator assembly (100) for actuating a dispenser (10) is disclosed. The dispenser (10) is in the form of a glass ampoule assembly (10) having a rupturable glass ampoule (12) containing a flowable material (M). The glass ampoule (12) is contained within an outer container (14) wherein the outer container (14) has a first open end (22) and a second closed end (24). The glass ampoule assembly (10) has an applicator (16) positioned in the first open end (22). The dispenser actuator assembly (100) has a base member (102) configured to mount on the outer container (14). The dispenser actuator assembly (100) also has an actuator assembly (104) operably connected to the base member (102) wherein the actuator assembly (104) has a first actuator arm (132a) and a second actuator arm (132b) each pivotally connected to the base member (102). The first actuator arm (132a) and the second actuator arm (132b) extend from the base member (102) in generally opposed relation defining a first position, or neutral position. The first actuator arm (132a) has a first protrusion (150a) depending therefrom and the second actuator arm (132b) has a second protrusion (150b) depending therefrom. The first actuator arm (132a) and the second actuator arm (132b) are pivotable from the first position towards one another to a second position, or actuating position, that is configured such that the first protrusion (150a) engages the outer container (14) and the second protrusion (150b) engages the outer container (14) to crush the glass ampoule (12) wherein the flowable material (M) is configured to be dispensed from the glass ampoule assembly (10).

The invention relates to a nozzle having a piercing projection for safe and efficient release of viscous material from a collapsible tube sealed at a front end and a rear end by tie clips when housed within a dispensing tool. The piercing projection extends from the nozzle interior surface. The piercing projection is arranged to pierce the front end of the collapsible tube along a tear line to form a flap of the collapsible tube to which the front end tie clip remains attached. An upstanding wall extends from the nozzle interior surface to define a retention shelf between the upstanding wall and the nozzle interior surface. The retention shelf is configured to receive and retain therein the flap and the front end tie clip during dispensing to enable unobstructed flow of the viscous material through the dispensing end opening.
