Abstract
An injection-molded plastic dispensing cap providing a semicircular spoon opening through which spoonfuls of the contents of an associated container can be removed. The cap provides a hinged flap for closing the opening which is hinged to the body and movable between an open position and a closed position. The cap provides an inwardly extending lip along the periphery of the opening. A rib is formed on the flap to closely fit the lip along the opening when the flap is in the closed position. Projecting from the rib is a latch projection fitting under the lip to secure the flap in the closed position. The lip is provided with a central recess bridged by the latch projection. The lip and the latch cooperate to provide spaced and opposed latching portions which are relatively insensitive to variations in the torque applying the cap to an associated container and which are not adversely affected by removal of the cap from its mold while the cap is still relatively hot.
