A trigger-vented mechanism for venting a container of a trigger-activated mechanism used for dispensing a fluid, comprising:

• a. a housing having one opening and comprising a fluid pump mechanism having an inlet in fluid communication with a container filled with a fluid and an outlet in fluid communication with a discharge outlet for dispensing said fluid,
• b. a vent tube extending from said container to said opening and providing air communication between said container and said opening, said vent tube having at least one resilient, collapsible portion;
• c. a pole member fixedly positioned between said container and said opening in proximity to said resilient collapsible segment of said vent tube;
• and
• d. an actuating trigger mounted in communication with said trigger-activated mechanism and having a distal side for compressive engagement by a user of said trigger-activated mechanism and a proximal side facing said pole member and said vent tube, said proximal side comprising means for collapsing said resilient collapsible segment of said vent tube against said pole member such that a fluid cannot flow in said vent tube when said trigger is not compressively engaged and such that a fluid can flow in said vent tube when said trigger is compressively engaged.

A trigger-vented/activated mechanism for dispensing a fluid and for venting a container of a trigger-activated mechanism used for dispensing a fluid, comprising:

• a) a housing having one opening and comprising a fluid pump mechanism having an inlet for receiving a fluid from a fluid filled container and an outlet in fluid communication with a discharge outlet for expressing said fluid;
• b) a dip tube extending from said inlet and providing communication for said fluid between said pump mechanism and a reservoir for said fluid;
• c) a discharge tube extending from said outlet, said discharge tube having at least one resilient, collapsible portion, said discharge tube providing communication for said fluid between said pump mechanism and a discharge outlet from said trigger-vented/activated mechanism
• d) a vent tube extending from said container to said opening and providing air communication between said container and said opening, said discharge tube having at least one resilient, collapsible portion;
• e) a pole member fixedly positioned between said pump mechanism outlet and said discharge outlet in proximity to said resilient collapsible segment of said discharge tube and said resilient collapsible segment of said vent tube;
• and
• f) an actuating trigger mounted in communication with said trigger-vented/activated mechanism and having a distal side for compressive engagement by a user of said trigger-vented/activated mechanism and a proximal side facing said pole member, said discharge tube and said vent tube, said proximal side comprising means for collapsing said resilient collapsible segment of both said discharge and vent tube against said pole member such that a fluid cannot flow in said discharge and vent tube when said trigger is not compressively engaged and such that a fluid can flow in said discharge and vent tube when said trigger is compressively engaged.
