It is made of elastomeric material, preferably rubber, and is shaped so as to include between about 2 and about 12 successive levels, each level having a larger diameter than the level before it. This multi-level cap is useful for capping water or sanitary systems during testing of the systems. The cap preferably has 3 levels which fit three different standard sized pipes, one pipe at a time.

Abstract: A reusable dust cap for tubing connectors on medical devices has an internal shoulder or ridge which engages a barb or groove on the connector to hold the cap during shipment. A grasping nub is provided on the cap to allow the cap to be forcibly disengaged from the barb or groove by the end user.

Abstract: A thin walled lid formed of a thermoplastic material having a generally circular center portion and an outer rim portion which fits over the cup bead and includes an integral peripheral skirt which makes up the outer side wall of the lid is disclosed. Located between the rim portion and the center portion is a recess or annular trough with an inner wall and an outer wall. The outer wall is separated into two shelves and three vertical sections. The lower shelf serves as a receiver ring upon which the lid above rests. The short vertical section located above the receiver ring effectively prevents any lateral movement of the lid above, while the lowest wall section forms the stacking ring and generally has a negative slope toward the lid skirt. Spaced periodically around the circumference of the stacking ring are positive draft flutes which have a positive slope away from the skirt and toward the center of the lid. The recess has a generally flat bottom which connects the stacking ring to the inner wall.

Abstract: A vent assembly for the top panel of a seal for a food container including a vent hole in the seal panel at least partially surrounded by an upwardly opening recess with the vent hole and recess being below the upper surface of the seal panel. A vent cover, including a depending plug selectively receivable in the vent hole, is pivotally mounted by a hinge assembly which included a hinge pin on said cover received within spaced trunnion openings in the recess adjacent the vent hole. The trunnion openings are laterally enlarged relative to the pin diameter and of a generally non-symmetric oval configuration.

Abstract: A child resistant lid is disclosed for use in conjunction with the standard build bucket for containment of materials. There is provided a threaded capped access opening of sufficiently small dimension to prevent the passage of a child's head, yet of sufficiently great dimension to allow for access to the material contained within the bucket. In addition, there is provided a handle grasp member and tool grip to aid the user in opening the threaded capped access opening. When it is desired by the user to pour the material directly from the bucket, there is provided a pour spout formed on an outermost peripheral edge of the lid and an air inlet opening formed on the cap member. The lid member of the present invention has provided a permanent locking mechanism to aid the user in permanently attaching the lid member to the lipped edge found on buckets of the type to be used in conjunction with the lid and to further serve as a safety feature.

Abstract: A container lid and container body locking mechanism includes a plurality of annular flanges and annular notch rings respectively and spaced apart in a pre-determined configuration so as to provide a tight leak-proof seal when the lid is fitted over the container body. A tamper proof detachable strip is provided in the container lid.

Abstract: The present invention concerns a system for closing cylindrical containers, such as Petri dishes, for example, with a cover cap whose cover apron presses against the outer surface of the lateral wall of the container. In particular, the present invention provides a cylindrical container and cover system having a simple and convenient, yet secure, closing and opening mechanism which consists of as few individual parts as possible. The cover cap of the present invention has individual elevations on the inner surface of the cover apron. The elevations press against the outer surface of the container walls to hold it in a non-positive manner. The elevations are made as knobs or elongated struts, and are arranged on opposite circular sections of the cover apron in such a way that at least two opposite sections of at least 130.degree. of the periphery of the cover apron have no elevations. In accord with the invention, a simple mechanism for removing the cover cap from the container is also provided.

Abstract: A single piece container closure and eating utensil wherein a container closure and an eating utensil of relatively conventional design are joined by a thin living hinge, such that the eating utensil can be easily folded under the container closure and be retained enclosed between the container closure and the covered container containing the food product prior to use. The container closure/eating utensil assembly can be fitted to standard commercial containers, the eating utensil is protected against contaminants prior to use, and the eating utensil is immediately available for use in a clean and sanitary condition as the consumer opens the container.

Abstract: A lid has a manually operable latching arrangement which prevents inadvertent disengagement of the lid from a container body even during severe service conditions. Latching is effected by a captive plate on the lid, the plate carrying a latching strap and a blocking member. In the latching position, the blocking member engages under a lip or flange at the upper edge of the container body, and the plate is retained in the latching position by engagement of the latching strap with an abutment in the lid.

Abstract: A dynamic joint connection is provided between the neck region of a base and the engagement end of a cap. The neck region comprises a reduced diameter end of the base which is offset from the base outer wall by a flat ledge. Located above the ledge a first axial distance, is a first convex rib. The interior surface of the cap engagement end is provided with a cap rib which is located a third axial distance above its abutment end. The third distance will locate the cap rib against the first rib on the down-sloping portion of its surface when the cap abutment end is in contact with the neck region ledge. The compressive force of the cap ring against the first rib will cause the abutment end to be biased downwardly against the ledge. This unstable condition creates a dynamic connection that maintains its integrity throughout rough handling, internal pressures and varying ambient conditions. The neck region can include a second rib.

Abstract: A food storage container includes a cylindrical barrel with an enclosed bottom for receiving a plurality of toroid shaped food products, such as bagels.
