220231000 | With vacuum breaker or manually operable vent | 11 |
20080217335 | Vacuum seal cover of circular container - A vacuum seal cover of a circular container has a circular tabular seal ring, so that the container no longer needs a fixing protrusion, and the cover includes a sheathing hole, a plurality of air holes disposed around the cover, and an umbrella valve installed at the sheathing hole and provided for vacuuming the container or releasing the pressure through the umbrella valve. The cover is installed at an opening of the container, and the air in the container can be extracted by an air extracting device to define a vacuum and maintain the interior of the container at a vacuum condition, so as to extend the expiration of the contents stored in the container. | 09-11-2008 |
20080257884 | Cap for a Receptacle - Closures for container openings, which comprise: a tap ( | 10-23-2008 |
20100270304 | SEALED COVER - A sealing cap, which is a cap body ( | 10-28-2010 |
20100294767 | CONTAINER OF THE TYPE COMPRISING A RECEPTACLE AND A HINGED LID - The invention relates to a container comprising: a receptacle comprising an internal cavity designed to accommodate contents, and an opening; a lid capable of closing the opening; means for connecting the lid to the receptacle in such a way as to allow the lid to pivot with respect to the receptacle; and a capsule arranged between the receptacle and the lid, which capsule hermetically seals the opening; in which the capsule is held against an edge of the opening by negative pressure inside the cavity. | 11-25-2010 |
20100326987 | VACUUM PACKAGING IN CONTAINERS PROVIDED WITH AN AIR-TIGHT CLOSING LID - A vacuum seal valve is applied to a lid for the air-tight closing of a container for the packaging of products, particularly food products, including a closing body arranged for sealing a hole for evacuating air from the container, from which at least one punching member stems that is adapted to pierce the lid closing the container so as to form such evacuating hole. A reciprocating mechanical vacuum pump, with manual actuation, evacuates air from a container arranged for the vacuum packaging of products, for example food products, via application of the vacuum sealing valve. The pump has, at its base, a recess adapted to form a housing for retaining the valve, whereby the lowering movement of the plunger allows driving the valve in a lid of the container. | 12-30-2010 |
20120091136 | VENTED CONTAINER - A container comprising a cover hingedly connected to a tray, with both the cover and tray having cooperating structures that form a closure when the container is closed, with a vent structure provided in the container for venting the interior of the container. | 04-19-2012 |
20120118888 | SELF-VENTING CONTAINER - A container having venting means and a method for sealing a lid to the container without damaging or weakening the container are disclosed. The container, such as a cup, includes venting means in the interior surface of the container side wall generally adjacent a lid seal to allow air that would otherwise be forced into and become trapped in the container when the lid is sealed to the lid seal to vent from the container to prevent weakening of, damage to or ultimate failure of the container. | 05-17-2012 |
20130082054 | SAFETY DEVICE AGAINST EXCESS TEMPERATURE - A safety apparatus for containers loaded by gas pressure, in particular the gas side ( | 04-04-2013 |
20140263320 | Beverage Can End With Vent Port - A can end for a beverage container has a center panel with a stay-on tab opening system. A tear panel is defined by a first frangible score and a non-frangible hinge segment. A tab is attached to the center panel by a rivet. The tab has a void region partially surrounding a rivet island. A first circle has a first center point located at a center of the rivet and a first radius equal to a distance from the center of the rivet to a radially outermost point of the void region on a first axis running through the nose and lift ends of the tab and a center of the rivet. A second circle has a coincident center and a second radius less than 2.5 times first radius. A second frangible score is spaced completely radially outwardly from the rivet island and between the first and second circles. | 09-18-2014 |
20150102032 | NON-SPILL DRINKING CONTAINER - A non-spill container assembly having a container, a collar and an annular seal from which drinking can occur at any location around a rim of the container assembly. The collar has an internal frustoconical shape wall with a circular upper end that extends downward and inwardly into a closed lower end. The closed lower end has a projection that extends outward from its center. The collar includes a support surface arranged along an inner surface of an upper edge of the circular upper end and a fastener assembly disposed adjacent to a bottom of the collar provided to securely fasten to a container. A plurality of passages are radially disposed around the projection in the internal frustoconical shape wall to channel a fluid. A plurality of radial protrusions disposed radially adjacent to the support surface defining various channels along the support surface. An annular seal is constructed in a form of a frustoconical disc substantially similar to a shape of internal frustoconical shape wall, the annular seal having a blind bore recess on a lower surface at its center for receiving and securing onto the projection. | 04-16-2015 |
20150307243 | BEVERAGE CONTAINER DEVICE FOR OPENING A DRINKING APERTURE AND VENTILATION APERTURE - A beverage container lid for use with a beverage can has a lid member. The lid member has a sealed perforated opening and a sealed perforated vent hole disposed thereon. A tab member is pivotally and rotatably coupled to a top surface of the lid member. The tab member has a first end and a second end. The second end is aligned and positioned above the sealed perforated opening. A protrusion extends down from a bottom surface of the first end member. The tab member is rotated to align the protrusion above the sealed perforated vent hole. Pressing downward on the first end of the tab member forces the protrusion to applying pressure to open the sealed perforated vent hole. | 10-29-2015 |
