Abstract
A system is provided for holding a dispensing valve that has a peripheral mounting flange and that is operable to discharge the contents from the interior of a container. The system includes a body for extending from the container. The body has a seat for engaging part of the valve mounting flange. The body has a resilient hinge and a protrusion that (1) extends from the hinge, and (2) has an abutment surface. The system includes a retainer for mounting to the body. The retainer has a seat for engaging part of the valve mounting flange. The retainer has a resilient hinge and an engaging member that (1) extends from the retainer hinge, and (2) has an abutment surface. The hinges accommodate deflection of the protrusion and engaging member as the protrusion and engaging member move past each other and establish abutting engagement of the protrusion abutment surface with the engaging member abutment surface as relative movement is effected between the body and retainer so as to clamp the valve mounting flange between the body seat and retainer seat.
