ABSTRACT:
A relatively lightweight dispensing cap closure includes a base cap portion for attaching to a container opening and a closure portion mounted for pivotable movement in a depressed socket formed in a top surface of the cap. The top surface is formed with a dispensing orifice and the closure portion is formed with a stopper member which cooperates with the dispensing orifice to open and close the cap. The closure portion has a downturned rear flange portion which is received in the socket to permit the closure portion to lie in a substantially horizontal, closed condition with the stopper plugging the dispensing orifice and a substantially upright, opened condition whereby the closure portion is positioned out of the flow path through the dispensing orifice. The flange portion of the closure is formed with a restricted throat opening for receiving a relatively wider upright post member, in the socket, such that the closure portion is biased from a position approaching the vertical to a fully open position bent back from the vertical. A stop surface is provided to limit pivotal movement of the closure portion in the opened condition. The closure portion is provided with a leading lip surface which overhands the peripheral profile of the cap top in the closed condition to receive application of an upward force thereto for dislodging the stopper from the dispensing orifice and raising the closure portion to the opened condition. The lightweight construction of the inventive dispensing closure enables only a slight upward force to be necessary to raise the closure portion from its closed condition.
