The present utility model relates to a structural arrangement for a bottle cap, belonging to the technical field of packaging accessories in general, more particularly to a cap for beverage bottles, such as beer, water, soft drinks, or any other drink or product for which the bottle is used as a packaging container, producing convenient, safe and functional results which are very advantageous. The innovation comprises a cap (10) to which an opening device (30) is coupled by a clip in the central top part. The cap (10) has a breaking zone (101) and a central hole (102) for coupling the clip (20) which links the cap (10) to the cross-shaped opening device (30) which forms four levers (302) with protruding projections (303) on the top surface and with a piercing point/tooth (304) on the underside of each lever (302), which pierces the breaking zone (101), allowing the inner pressure to escape and thus making it easier to remove the cap (10) with the lever formed at the opposite end.

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.

A re-closable vent for a container closure which requires no pre-formed holes in the closure deck, provides a tamper-evident feature, and provides simple rotation of a cap structure to open and a vent after punching out a frangible deck section.

A beverage can end includes a filling port in the end itself. An activating gas that interacts with the beverage may be charged through the filling port. If the end has a vent opening, such as sometimes used in a recloseable end, the vent opening may be used for charging the activating gas.

A sheet metal lid has a rim portion removably secured to a container and includes a vent button having a top wall portion surrounded by a side wall portion and an outwardly projecting flange portion. A portion of the button has an arcuate shear line extending substantially into or through the sheet metal, and the sheet metal is flattened or compressed at the shear line to form positively connected opposing sheet metal portions. A resilient sealant material is bonded to the inner surface of the vent button, and the opposing sheet metal portions and the sealant material form a small gap for releasing a vacuum or pressure from the container in response to downward pressure on the top wall portion of the vent button.

A sheet metal lid has a rim portion removably secured and sealed to a container and the lid includes a vent button having a top wall portion surrounded by a side wall portion and an outwardly projecting flange portion. The flange portion of the button has a short arcuate score or shear line extending substantially into the sheet metal, and additional score lines extend into the flange portion at lesser depths to protect a coating on the inner surface of the lid. A resilient sealant material may be bonded to the inner surface of the vent button, and the opposing sheet metal portions of the score line form a small gap for releasing a vacuum or pressure from the container in response to a controlled downward pressure on the top wall portion of the vent button.

A liquid receptacle system comprising: a receptacle comprising a bowl (3) having an upper opening surrounded by a rim, wherein a screw thread is provided on the interior surface of the bowl, substantially adjacent said rim; and a removable closure (6) for sealing the bowl, the closure having a corresponding external screw thread which in use engages with the interior screw thread of the bowl to enclose contents within the bowl.

A device is provided that assists with equalizing air pressure within a container with the atmospheric air pressure as liquid is being poured from the container and includes one or more relatively short air tubes. The device is provided with the ability to simultaneously equalize pressure in the container while also providing a drip collection mechanism. The device may be configured for unidirectional pouring or multi-directional pouring.

Closure for a container mouth, the closure comprising: a cover portion (18) for covering at least a portion of the container mouth; a fastener portion (20) for engaging the container for fastening the closure to the container; and a peelable bracing portion (22) extending generally in a circumferential direction of or around an axis of the closure, the bracing portion overlapping at least partly the cover portion and the fastener portion, and configured to reinforce the closure by bearing, as shear stress at an interface between the bracing portion and at least one of the cover portion and fastener portion, support force in or between one or both of the cover portion and the fastener portion.

A sheet metal lid has a rim portion with a resilient sealant for releasably coupling and sealing the lid to a glass or other container enclosing a vacuum food product. The lid is successively pressed with progressive dies to form an upwardly projecting and thinner dome-shape portion which is progressively formed into annular cavity surrounding a vacuum release vent button. The button has a sloping top wall with an upper edge portion connected to a substantially vertical arcuate wall portion adjacent an arcuate score line located in opposing relation to an arcuate reinforcing bead within the cavity. A sealant material is bonded to the inner surface of the button and overlies the score line. The vent button is preferably located below the rim both before and after the vacuum is released, and the sealant material reseats to cover the score line and protect the food product.
