PINCH CAP Abstract A pinch cap has a top wall with edge portions which form a circumferentially-extending rim. A pair of spaced, D-shaped, finger-receiving wells open through the top wall. The wells are formed by curved and straight side walls which depend from the top wall, and by a pair of D-shaped bottom walls. Locking formations are provided on the outer faces of the curved side walls for holding the cap in place in a container opening. During insertion of the cap into a container opening, the locking formations engage portions of the container located at spaced positions around the container opening and cause the normal configuration of the cap to distort briefly as is needed to permit the locking formations to pass through the container opening. Removal of the cap from the container opening is effected by pinching the flat side walls toward each other to distort the normal configuration of the cap sufficiently to release the locking formations from retaining engagement with the container, thereafter the cap is lifted out of the container opening. Venting grooves may be provided in the curved side walls and in the underside of the rim to permit the escape of gases through the container opening.
