Abstract
A dispensing closure having a cap adapted to be secured to a container so that it is substantially impossible to remove the cap from the container and having a spout rotatably mounted on the cap so as to be capable of being rotated between a closed position in which the spout covers an opening through the cap and an opened position in which the spout is in alignment with the opening can be easily modified so as to render the closure child resistant in character. The modification involves shaping the cap and the spout so that only the tip of the spout can be engaged to rotate the spout when the spout is in the closed position. The modification also involves forming a wall structure on the cap so as to define a slot, this slot being positioned so that the tip of the spout fits within it and is spaced from the bottom of the slot when the spout is in the closed position. The slot and the tip are dimensioned so that the tip cannot be directly engaged by a part of the hand of a user such as a finger, a thumbnail or the like so as to rotate the spout. The slot and the tip are also dimensioned so that a small coin can be inserted into the slot beneath the tip to rotate the spout from the c…
