Abstract: A safety container incorporates a slidable locking pin with an integral but separately lockable locking tab. The locking pin is internally biased by an integral S-spring which, in cooperation with the lid on the container, urges the pin to slide in a slideway in the lid of the container. The locking pin may be locked into a closed position, however, by rotation of the locking tab into a flexed position. In this position, the locking tab cannot slide within a mating slot in the hinge lid and thus the locking pin cannot slide in the slideway in the lid. Alternatively, the locking tab may be rotated into a non-flexed position in which the locking tab can be urged to penetrate the mating slot in the lid and allow the locking pin to slide in the slideway in the lid. By use of the locking pin, the safety container can be set to require the user to engage in at least distinct hand motions in order to open the container.

The lid frame is made of a first material and the connector is made of a second material. The connector is provided to support the lid for pivotable movement relative to the rim between a closed position wherein the lid closes the opening formed in the rim and an opened position wherein the lid lies away from the rim.

Abstract: A one-piece dispensing structure is molded by a process combining a co-injection molding first phase with a bi-injection molding second phase. In the first phase, a skin material and core material are co-injected into a mold cavity first region to form most of the major portion of the closure body. Subsequently, a movable shut-off member is retracted to expose an intermediate region which (1) is adjacent the closure structure hinge area and which (2) establishes communication between the mold cavity first region and another part of the mold cavity defining the closure lid portion. The skin material is injected through a second gate directly into the cavity intermediate region to fill the cavity intermediate region and the closure lid portion of the mold cavity. The skin material in the cavity intermediate region bonds to the previously injected skin material in the cavity first region adjacent the closure hinge.

Abstract: A closure assembly to facilitate the sealing of each of a series of necked containers, each of different body configurations and contours, with the same hinged lid. The invention thus obviates the need for relatively complex and costly molds and effects substantial savings in manufacturing costs. The first component of the closure assembly is an adapter for mounting on a given particular container. The adapter includes a skirt for sleeved securement onto the neck of the container. A plate of the adapter overlies the container neck and is formed with a through port for discharge therethrough of material stored in the container. A second component of the closure assembly consists of a lid assembly, the same lid assembly being readily attachable to each of the different adapters, and, thus, to each of the different containers. The lid assembly includes a cover overlying the plate of the cap.

Abstract: A lidded insulator for a beverage container comprising an insulator lid hingedly attached to an insulator body by means of a hinge. An insulator top ring having an insulator top ring bore is attached to the insulator lid. The hinge is made of resilient material possessing material memory tending to urge the hinge into a straight position. This hinge material memory tends to urge the insulator lid into a closed position. The lidded insulator for a beverage container is sized to frictionally admit a standard sized beverage container. Thus the beverage container is held securely within the insulator body, and when the insulator lid is closed on the beverage container, the frictional fit between the insulator lid and the beverage container holds the top closed, and together with the hinge material memory, urges the insulator lid top into sealing relationship with the beverage container opening.
