Airless dispensing pump with tamper evidence features

摘要: An airless dispenser pump assembly includes a mechanism with an inlet valve that is configured to efficiently viscous fluids and able be pre-primed when the attached container. In one form, seal member seals port of outer support secures rest mechanism. Two or more legs generally extend in circumferential direction between order create large flow opening for fluid through opened rapidly close valve. The further outlet draw back from nozzle after dispensing minimize build up around nozzle.
