Abstract
A child resistant dispensing closure of the type comprising a cap member and a spout member. The cap member is provided with an exterior skirt, a top surface having an elongated groove formed therein, and an interior skirt. The interior skirt is provided with a cap locking bead adapted to engage a container locking bead provided on the neck of a container for rotatably mounting the cap member on the neck of the container. The elongated groove has a dispensing opening and an open area formed therein, and the interior skirt is provided with an interruption at the location of the open area so as to maintain the area unobstructed. The container locking bead is also provided with an interruption. The spout member includes an elongated body having a longitudinal dispensing passage therein and adapted to be mounted at one end in the elongated groove for rotation with respect to the cap member. The spout member is provided with a depending locking prong adapted for insertion into the open area. The spout member is adapted to assume an open position wherein the spout member is oriented vertically with respect to the cap member and the dispensing opening and longitudinal passage are in communication. The spout member is capable of being rotated from the open position downwardly toward the cap member to achieve a closed position wherein the locking prong is received within the open area of the cap base member and the interruption in the container locking bead.
