DEFINITION

Classification: 24/671

Partially blocking separate, nonresilient, access opening of cavity:

(under subclass 662) Receiving member wherein the resiliently biased component extends across or into a portion of the travel path of the projection to (a) reduce the width of this path, and (b) hinder the removal or entrance of the projection through a separate (i.e., nonintegral) nonresilient component of the receiving member which forms the access opening of the cavity.

(1) Note. If the resilient* element is located at one side of the access opening, it is proper for this and the indented subclasses only if structure of the nonresilient component is also found on this side and radially spaced a further distance from the central axis of the access opening.
