  • Patent number: 11053050
    Abstract: A liquid container is screwed to tighten and seals strongly, and wherein torque reduction for opening the cap is controlled to prevent loosening the cap, preservation of a tightly-sealing property is improved, and content leak is prevented. The container includes: a body having a male screw on the mouth-neck section rising from the surface; and an anti-loosening cap having a female screw engaging with the male screw and a buffer seal material on the inner side of a top plate, a flange protruding from an open end portion of an outer cylinder skirt extending from the top plate, a resin cushion material protrusion on the flange and attached onto the outer surface of the flange, a height difference of the top plate inner surface to the protrusion top is larger than a height difference from a container opening end face of the mouth-neck to an outer surface portion and protrusion.

  • Patent number: 10974859
    Abstract: A polymeric container including a base, a body, a finish, finish threads, and a tamper lip. The body extends from the base. The finish defines an opening through which a product can pass into, and out of, an internal volume of the container defined at least in part by the body. The finish threads are at an outer surface of the finish, and are configured to cooperate with closure threads of a closure to secure the closure to the finish. The tamper lip extends from the outer surface of the finish, and is configured to replace the support flange during handling, and to cooperate with a tamper band of the closure. A recess is below the tamper lip. The recess retains the tamper band therein when the closure is removed from cooperation with the finish.

The seal provides a leak proof closure that is strong enough to remain intact when the filled uncapped container is held in an inverted position, and at the same weak enough to break open and dispense the contents into a fill opening when a consumer squeezes the inverted container. The seal is constructed from a first layer of leak proof frangible sheet material that is bonded to a second layer of strengthening sheet material. The strengthening layer contains a cut out void configuration that forms a breaking pattern which forces the seal to break open only in the weaker single frangible layered configuration of the cut out void forming the breaking pattern when the container is squeezed.

An annular plug depends from an underside of the top and one or more ribs are formed on an internal surface of the downwardly extending skirt portion. The annular plug and the one or more ribs are arranged concentrically and are dimensioned such that, upon application of the cap to the neck structure, the annular plug projects into the neck opening and engages the cylindrical sealing surface. At the same time the one or more ribs engage the external neck surface.

  • Publication number: 20020066714
    Abstract: A vented closure, for preventing deformation of a container containing a gas evolving liquid, is provided. The closure includes a first closure member and a second closure member. The first closure member seals the container from the outside atmosphere and defines a gas inlet, a gas outlet and a gas flow passage between the inlet and the outlet. A gas-permeable, liquid-impermeable membrane is placed in the gas flow passage. The second closure member is moveably fitted on the first closure member and encases the first closure member with a small clearance fit that allows gas passage. A sealing element coupled to the second closure member is aligned with the gas outlet of the first member so as to block gas flow when a predetermined load is applied to the second closure member and allow gas flow when the predetermined load is absent.

  • Patent number: 6364152
    Abstract: A food storage container 10 includes a base 12 and lid 14. The base 12 has a sealing flange 22, and the lid 14 has a sealing lip 32 which seals against the sealing flange 22 as with a suction cup. The lid 14 may include resilient deformable sections 46, 50, to aid in maintaining reduced pressure within the container. The lid 14 may include latch prongs 54 to mechanically retain the lid 14 in position. The latch prongs 54 may be designed to automatically release during heating of the food, permitting venting. The sealing lip 32 may include seal spacers 60 which permit air to enter the food storage container 10 during serving of hot food to avoid creation of reduced pressure in the container. The seal spacers 60 do not interfere with normal creation of a seal when desired.

  • Patent number: 6062407
    Abstract: A capping and sealing assembly for a sample-holding centrifuge container which features a self-sealing lid that forms a fluid-tight seal in an opening of the canister with a predetermined amount of force, with the force being dependent upon the centrifugal load to which the capping assembly is subjected. The lid includes a cover portion and a peripheral member surrounding the cover portion and extending transverse thereto. The lid is disposed within an open end of the container, with the peripheral member having a frusto-conical surface that faces the container's wall. A gasket is disposed about the frusto-conical surface, forming a fluid-tight and air-tight seal with the cylindrical wall of the canister. The gasket is received in a channel formed into the frusto-conical surface. A region of the channel includes a vent slot to facilitate removal of the container from the canister. A plurality of arcuate ribs extend across the cover portion, between opposed areas of the peripheral member.
