Closure Structure Specified For Stacking Patents (Class 206/508)
  • Patent number: 5813561
    Abstract: This invention comprises a sanitary beverage can lid wherein the center platform of the lid including the pull tab is raised from below the rim of the can as in conventional cans to a position close to or slightly above the rim of the can. The center platform diameter is reduced in diameter to provide additional space from the exterior of the can body to the edge of the platform. The pull tab is positioned in the middle of the center platform so that the end of the pull tab is at the edge of the center platform to facilitate opening of the can. The raised center platform and the lid design prevent an individual's lip from coming in contact with the groove along the edge of the lid where dirt may accumulate. Another feature is the provision of a raised rim on the platform with an interior drain-back slope so that any excess beverage flows back into the can.

  • Patent number: 5791509
    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.

  • Patent number: 5692634
    Abstract: Rigid container structure for hermetic sealing of particulate solids which emit an off-gas during containment. Provisions are made for enclosing chamber space with a gas-permeable imperforate membrane film so as to selectively separate and retain an off-gas out of contact with container contents. In a specific embodiment, carbon dioxide is selectively separated from coffee contents while the entire container, including such enclosed chamber as established, is hermetically sealed from ambient atmosphere. Provision is also made for venting of a separated off-gas in initiating a rupture of an end closure structure prior to full opening of the container. That arrangement further diminishes the opportunity for inadvertent discharge of particulate solids due to expulsion of gas from inert gas purging and from gas emitted during hermetic sealing.

  • Patent number: 5499715
    Abstract: A stackable container for computer media, such as floppy disks or the like. The container comprises a base and a removable cover. During ordinary use of the container, the cover fits in an upright orientation securely atop the base to provide closure of the container. The cover is constructed so that when it is removed and inverted, it nests in the base of the container. Thus, during packing and shipment (or storage) of the container, the cover is removed and inverted and nested in the base. The cover, which is typically made of clear styrene, is relatively brittle, and the ability to nest the cover in the base, which is typically made of a more resilient plastic, provides protection from physical damage to the cover during shipment. Also, the base is constructed to at least partially nest in the inverted cover, so that multiple containers can be packed and shipped more compactly.

  • Patent number: 5409126
    Abstract: A storage container which includes a base within which is defined a storage compartment. A lid is to be connectable with the base closing the storage compartment to the ambient. The lid is bulbous so that relative to the storage compartment it can be located in a concave position decreasing the size of the storage compartment or a convex position increasing the size of the storage compartment. This reversibility of the lid can be achieved by constructing the lid so as to actually be physically reversible or also by having the lid to be physically deflectable from the convex position to the concave position.
