Dispensing systems
An overcap ( 102 ) includes a housing ( 106 ) for coupling to a container ( 104 ). The housing ( 106 ) has a first side-wall ( 306 ) including an aperture ( 500 ). The overcap ( 102 ) also includes a trigger ( 108 ) having a grip portion ( 300 ) disposed outside of the housing ( 106 ) and an arm ( 400, 402 ) extending through the aperture ( 500 ) of the first sidewall ( 306 ) and pivotably coupled to a fulcrum ( 504 ) spaced apart from the first sidewall ( 306 ). The overcap ( 102 ) further includes a cap ( 110 ) coupled to the housing ( 106 ) and a manifold ( 600 ) suspended from the cap ( 110 ).
1. A dispensing system, comprising:
a housing for coupling to a container, the housing having a first sidewall including an aperture;
a trigger having a grip portion disposed outside of the housing and an arm extending through the aperture of the first sidewall and pivotably coupled to a fulcrum spaced apart from the first sidewall;
a cap coupled to the housing; and
a manifold suspended from the cap,
wherein a lowermost point of the grip portion is to move along a first arcuate path, and a portion of the manifold is to move along a second arcuate path opposing the first arcuate path when the trigger moves from an unactuated position to an actuated position.
2. The dispensing system of claim 1 , wherein the portion of the manifold is to move toward the first sidewall when the portion of the manifold moves along the second arcuate path.
3. The dispensing system according to claim 1 , wherein the manifold is unitary with the cap.
4. The dispensing system according to claim 1 , wherein the manifold includes a protrusion and the trigger includes a cam to engage the protrusion.
5. The dispensing system according to claim 1 , wherein the trigger comprises a second arm spaced apart from the arm to define a space, the manifold extending through the space.
6. The dispensing system according to claim 1 , further comprising a spring coupled to the arm, the spring to compress between the arm and the housing.
7. The dispensing system according to claim 1 , wherein the manifold includes a duct having a first flexure area and a second flexure area.
8. The dispensing system according to claim 1 , wherein the arm is pivotably coupled to a rib disposed on a second sidewall of the housing opposite the first sidewall.
9. The dispensing system according to claim 1 , wherein a lower end of the grip portion of the trigger is to move toward the first sidewall to move the trigger into engagement with the manifold.
10. The dispensing system according to claim 1 , wherein the dispensing system has a longitudinal axis, and further comprising:
a discharge aperture in fluid communication with the manifold, wherein the manifold has an end portion to receive a valve stem of a container, and wherein a first plane perpendicular to the longitudinal axis passes through the discharge aperture, a second plane perpendicular to the longitudinal axis passes through an axis of rotation of the trigger, and a third plane perpendicular to the longitudinal axis passes through the end portion of the manifold, wherein the second plane is disposed between the first plane and the third plane.
11. The dispensing system of claim 10 , further comprising a container including a mounting cup, wherein a fourth plane perpendicular to the longitudinal axis extends through a lowermost point of the mounting cup, and wherein a lowermost point of the grip portion of the trigger is disposed below the lowermost point of the mounting cup when the trigger is operatively coupled to the container.
12. The dispensing system of claim 1 , wherein the manifold includes a first joint and a second joint.
13. The dispensing system of claim 12 , wherein the first joint comprises a link disposed between the manifold and the cap.
14. The dispensing system of claim 12 , wherein the second joint comprises a brace coupled to a first duct of the manifold and a second duct of the manifold.
15. A dispensing system, comprising:
a housing for coupling to a container, the housing having a first sidewall including an aperture;
a trigger having a grip portion disposed outside of the housing and an arm extending through the aperture of the first sidewall and pivotably coupled to a fulcrum spaced apart from the first sidewall;
a cap coupled to the housing; and
a manifold suspended from the cap,
wherein a lower end of the grip portion of the trigger is to move toward the first sidewall to move the trigger into engagement with the manifold.
16. The dispensing system according to claim 15 , wherein the manifold is unitary with the cap.
17. The dispensing system according to claim 15 , wherein the manifold includes a protrusion and the trigger includes a cam to engage the protrusion.
18. The dispensing system according to claim 15 , wherein the trigger comprises a second arm spaced apart from the arm to define a space, the manifold extending through the space.
19. The dispensing system according to claim 15 , wherein a lowermost point of the grip portion is to move along a first arcuate path, and a portion of the manifold is to move along a second arcuate path opposing the first arcuate path when the trigger moves from an unactuated position to an actuated position.
20. The dispensing system of claim 19 , wherein the portion of the manifold is to move toward the first sidewall when the portion of the manifold moves along the second arcuate path.
