ABSTRACT:
A "toggle" type dispensing closure can be constructed so as to utilize a first closure part such as a cap or the top of a container upon which there is pivotally mounted a second closure part such as a lid so that the second closure part may be pivoted between a closed position in which an opening through the first part is closed off and an open position in which material may be moved through the opening. With such a closure one end of a spring is pivotally connected to the first closure part and the other end of the spring is pivotally connected to the other closure part. The spring is connected to these two parts at spaced locations such that the distance between the ends of the spring is decreased as the second closure part is moved between these positions. Preferably, the entire dispensing closure is formed as an integral unit of a somewhat flexible, somewhat resilient polymer material in such a manner that the first part is mounted on the second by means of trunnions and bearings which are snapped together and in such a manner that the ends of the spring are connected to the parts by integral, flexible sections of the polymer material serving to pivotally connect the spring to these parts.
