Abstract
A container useful for singly dispensing a tablet includes a leaf integrally formed with the sidewall and projecting generally radially inward to a distal portion. One or more such leaves define a dispensing opening having a smaller diameter than the mouth of the container. The leaves or other undercut structure can be formed using a mold element having a leading portion for forming a portion of the part beyond the resilient projection and a following portion for forming a portion of the sidewall short of the resilient projection. The following portion is withdrawn at least partially away from the outside surface of the resilient projection, leaving a space between the leading and following portions. The leading portion is withdrawn from the mold cavity against an undercut portion of the resilient projection, folding the resilient projection into the space left by retracting the following portion.
