ABSTRACT:
This relates to a dispenser for paste-like products wherein there is a pump chamber disposed between a container for the product and a dispensing opening and the pump chamber and an adjacent duct have associated therewith flow control inlet and outlet valves. The principal feature resides in the provision of a separate insert which is telescoped between a container and a head member and which insert defines a pump cylinder and a discharge duct and carries and inlet valve element and an outlet valve element. The inlet valve element is integrally formed with the insert while the outlet valve element may be selectively formed integrally with the insert or as a separate insert which may be readily incorporated within the primary insert.
