Abstract: For containers with circular openings, a closure for selectively loosely covering or tightly sealing the container. A seal member has an elastically contractible peripheral bead. The throat opening of the container decreases in diameter in two steps, forming two annular ledges and a wall portion therebetween. The peripheral bead may rest loosely upon the first, larger ledge, and, when contracted, may be seated tightly upon the second, smaller ledge.

Abstract: An adjustable carrier for multiple stacked containers, the carrier including a lower collar positionable peripherally about and lockably engagable with the lowermost container, an upper collar engagable about the uppermost container in cover retaining relationship therewith, and multiple straps engaged between the collars. Each strap is snap-locked to the lower collar and projects vertically into an adjustable ratchet and pawl engagement with the upper collar. The upper collar incorporates an integral handle which receives any excess length of the straps therein.

Abstract: A container encircling frame with opposed pairs of resiliently deformable straps extending therefrom. Each pair of straps mounts an elongated handle element transversely across the outer ends thereof, the two handle elements, upon a releasable interlocking thereof, defining a single handle or hand grip. Each handle element includes a vertical ribbed panel, with a laterally spaced lip defining a recess for the panel of the other handle element. Interlocking is effected through releasably engageable detents and projections on the panels and lips.
