ABSTRACT:
A two piece safety or child resistant dispensing closure for granular or pellet material. The opening of the dispensing window can be varied to control the rate of dispensing. One piece of the closure is a cap which is attached to the container by threads or a snap-on flange. The cap has a pair of opposed circumferential windows in its top. The second piece of the closure is a flat cover with corresponding circumferential dispensing windows. The cover is attached to the cap for rotation between an aligned window dispensing position and a closed, nonaligned window position. A pair of opposed rocker arms which may be depressed by the thumb and forefinger of the user is used to release the cover from its closed position and rotate it to a dispensing position. Detents on the cap coact with the rocker arms on the cover to secure the cover and cap with any desired degree of alignment between the windows on the cap and cover to achieve metered dispensing.
