Containers with closures are disclosed. A closure may include at least a polymer orifice reducer configured to be permanently secured to a rim of an opening of a container and a flexible tamper evident seal disposed on the topside of the orifice reducer. The flexible tamper evident seal, optionally foil, covers one or more openings in the orifice reducer. Processes for permanently securing a closure to a container, optionally by forming a heat seal between the orifice reducer and container rim, are also disclosed.

The present application improves the shape of a curl part of a bottle can to secure high sealability even under high pressure in the can and during heat sterilization, makes bubbling-over occur less during cap opening, and suppresses misrecognition of reseal.

A bottle can has a curl part provided at an opening end of a mouth part. The curl part includes an outer wall part extending downward from an upper end bent part. The outer wall part includes a first bent part shaping a locking part that extends continuously and downwardly from the upper end bent part and shapes an outwardly-protruding convex, and a second bent part that extends continuously and downwardly from the first bent part and shapes an inwardly-protruding convex.

Disclosed is a metallic cover cap for sealing a metallic bottle, comprising a gasket provided with a flat central zone and an annular zone which includes an outer rim and an inner rim that are separated by a notch, such that the outer rim extends axially, continues circumferentially, and includes: a first surface; a second surface with a flat portion and a concave portion radially opposite the notch; and a third flat surface that extends between the first and second surfaces, and the inner rim extends axially, continues circumferentially and spaced radially inwards of the first rim, and includes: a first flat surface opposite and perpendicular to the flat zone; a second concave surface radially opposite the notch; and a third flat surface between the first and second surfaces that is inclined toward the notch.

Non-removable closure assembly that resists rotational movement so as to be rendered substantially non-removable by the consumer. An induction heat seal liner is provided for sealing the finish (open end or mouth) of a plastic container, the liner being disposed between a closure cap and the container finish and being heat seal bonded to both, thus rendering the closure cap non-removable from the container finish. By non-removable it is meant that once heat seal bonded together the closure cap cannot be removed by a customer or consumer (a human) by hand, without substantially distorting the closure cap or container, e.g., it would require the human to use a mechanical tool (e.g., knife or wrench) and in the process of trying to remove the cap with the tool it would substantially deform the closure cap or container and render one or more of them unusable for their intended purpose.

Induction seal liners for containers include active polymer compositions that function as active agents within the container during storage of products and which may be easily removed and discarded after opening the container. The active agents can include antioxidant or oxygen scavenging materials, anti-melanosic agents, desiccants, antimicrobial agents, odor reducing agents, and others. The induction seal liners herein extend the shelf life of products while affixed to the opening of a container. An induction seal for a container, the induction seal comprising: a mounting sheet; and an induction seal liner attached to a headspace-facing surface of the mounting sheet, the induction seal liner comprising an active polymer component including a multiphase polymer composition, wherein a mounting portion is located or exposed between an outer edge of the induction seal liner and an outer edge of the mounting sheet.

A screw cap for wine bottles, has an outer capsule screwable to the bottle and an insert inserted in the outer capsule and intended to stay interposed between the mouth of the bottle and the outer capsule, is described. At the bottom, the insert is provided with a metal foil intended to directly stay in contact with the mouth of the bottle by intercepting the same. The metal foil is the only component of the cap wettable by the wine and is made of a precious metal inert at room temperature, or it is made of an alloy of precious metals inert at room temperature. The insert also has a gasket positioned on the metal foil, which has a radial extent larger than the metal foil itself, and has an outer crown surrounding the metal foil by adhering to the mouth of the bottle.

A closure includes an overcap having an annular skirt, and an annular wall extending inwardly from the skirt. A lid is carried by the overcap radially within the annular skirt, and includes a hub, and an annular margin extending radially outwardly with respect to the hub, and having upper and lower surfaces. An annular container seal extends circumferentially continuously around the annular margin. One or more vents may extend through the annular margin between the upper and lower surfaces thereof at one or more discrete circumferential locations radially inward with respect to the container seal. One or more vent seals may be disposed at the one or more vents between the lid and the overcap.

An assembly of a closure with a container, for sealing of the container, comprises the container having an inner container surface defining a cavity opening to ambient through an opening, the closure comprising an upper portion and a lower portion, the lower portion having a lower lateral surface, the lower portion being adapted to be inserted into the opening of the container and two grooves provided on the lower lateral surface and adapted to receive two respective sealing members, the two grooves being separated by a predetermined distance, the two sealing members provided in the two respective grooves, the two sealing members being adapted to provide sealing between the lower lateral surface and the inner container surface, wherein the lower lateral surface, the inner container surface and the two auxiliary sealing members together define an annular space and a barrier sealant in the annular space.

A vented grooved foam liner cap system for attachment to a container, including a vented foam liner having a grooved distal side that can be actuated from an open state to a sealed state within a cap of a container by a sealing mechanism. A method of equilibrating pressure and sealing a container, by venting contents of a container through the vented grooved foam liner cap system attached to the container, and after the contents have cooled to a desired temperature, stopping venting, thereby providing pressure equilibration to the container, and sealing the container by activating a sealing mechanism in the vented grooved foam liner cap system.

Containers with closures are disclosed. A closure may include at least a polymer orifice reducer configured to be permanently secured to a rim of an opening of a container and a flexible tamper evident seal disposed on the topside of the orifice reducer. The flexible tamper evident seal, optionally foil, covers one or more openings in the orifice reducer. Processes for permanently securing a closure to a container, optionally by forming a heat seal between the orifice reducer and container rim, are also disclosed.
