  • Patent number: 7837052
    Abstract: Apparatus and related methods for a container lid include a pull structure affixed to at least one end of a tamper evident tearstrip and positioned in an outer flange of the lid, the pull structure having a portion shaped to receive and engage a manipulator such as at least one finger of a user's hand, to assist the user to initiate tearing of the tearstrip from the lid. The shaped portion of the pull structure is configured to eliminate the need to grip the tearstrip between opposing digits of the user's hand. The lid may further include an extendible connection member positioned on at least one end of the tearstrip in an area or space generally defined as a “well.” Among other things, the extendible connection member can provide additional flex to a hinge portion of the lid, without destroying the subsequent tamper-evidencing value of the lid. A satellite ring may be attached to or provided on the lid or container to provide further tamper evidencing and protection to the lid assembly.

  • Patent number: 7784635
    Abstract: Apparatus and methods are disclosed for improved containers and lids, and combinations thereof. Multiple compartments are provided in a container, one of which can be formed as the container's handle. The lid incorporates a plurality of hinged openings situated on the periphery of the cover, and the container includes a molded unitary body plastic container comprised of at least two chambers or compartments. The lid openings can be located strategically over or adjacent the container chambers/compartments, to provide independent access thereto. The compartments or chambers within the container separate the contents thereof, while multiple hinged openings may allow access to individual or multiple chambers or compartments within the container. Tamper evidencing structures in conjunction with detents or engagement structures may hold the lid and container openings in the desired relationship during shipping, handling, storage, and/or use. Related methods are disclosed.

  • Patent number: 7740149
    Abstract: Apparatus and methods relate to containers having a sidewall portion with at least one generally vertical corrugation therein. The containers can be of a variety of shapes, sizes, cross-sections, and materials. The corrugation improves the container sidewall strength and resistance to buckling under compressive loads such as stacking of multiple containers.

  • Publication number: 20080083768
    Abstract: A cover for a container, in accordance with one embodiment that allows quick and easy access to products within the container. The cover for a container includes a pivot score line transversing the cover thereby forming a front cover portion and a back cover portion. The pivot score line pivotally connects the front cover portion and the back cover portion. The cover also includes a fastening device. The fastening device includes a first fastening component mounted on the front cover portion and a second fastening component mounted on the back cover portion. The first fastening component engages the second fastening component upon pivoting the cover at the pivot score line. Using the present embodiment, products may be repeatedly dispensed from a container quickly and easily.

  • Patent number: 6604647
    Abstract: A container includes first and second intersecting surfaces, and has at least one tearstrip opening to permit access to the contents of the container. The opening is positioned substantially at the intersection of those surfaces to permit drainage of substantially all of the contents of the container through the opening formed upon tearing of the tearstrip. Where the intersection is formed by a lid and a container wall, the lid has an outermost edge and the opening is positioned sufficiently near to the outermost edge to permit the desired drainage but also either does not tear the outermost edge (because the opening is sufficiently inwardly from the outermost edge) or does not destroy the hoop strength of a downwardly-depending hoop flange formed at the outermost edge. A plurality of such tearstrips may be provided and may be spaced from each other to provide pouring and/or venting in a variety of directions.

  • Publication number: 20020148847
    Abstract: Apparatus includes a lid and a container/lid combination and associated methods, in which the lid may be used selectively for either dry or liquid-sealed applications. For liquid-sealed applications, a gasket or similar sealing element is provided in a gasket channel. A shoulder or detent prevents the container from entering the gasket channel, but permits the desired liquid-sealing when the gasket or similar sealing element is present in the channel. The sealing element may be foamed-in-place within the channel.
