Abstract
A dispensing pump capable of withstanding the rigors of “e-commerce” shipping conditions is described. The pump dispenser is integrated with the container's closure. The pump includes a lock-down mechanism to prevent the pump actuator from extending during shipment, while a vented chaplet and an optional beaded seal proximate to the dip tube connection ensure that fluid cannot leak out of the container or the pump.
