20100102058 | VACUUM STORAGE CONTAINER WITH FLEXIBLE DIAPHRAGM - A vacuum storage container having a container body, a check valve and a lid with an outer rim surrounding a diaphragm. A vacuum pump is engagable with the check valve to remove air from the interior of the container to create a vacuum in the container. The diaphragm is pushed inward by atmospheric forces upon removal of the air until the diaphragm touches and conforms to at least upper exposed surfaces of the contents of the container. The storage container aids in preventing degradation of the contents of the container by maintaining the contents free from the degrading effects of air and by substantially immobilizing the contents during movement of the container to protect the contents from breakage and bruising. | 04-29-2010 |
20100237070 | STORAGE CONTAINER - A storage container for storing food items includes a base providing a storage cavity accessible by an opening and a detachable lid for covering the opening and enclosing the storage cavity. The lid may include a one-way valve to facilitate evacuation of the storage cavity after the lid has been attached. To provide a substantially air tight seal between the base and lid, a sealing member is included. The sealing member can be comprised of any suitable resilient material such as a thermoplastic elastomer. The sealing member can be integrally bonded to either the base or the lid by, for example, an overmolding process or a co-extrusion process. | 09-23-2010 |
20100282747 | CLOSURE WITH SAFETY FEATURE - Disclosed is a closure for a container wherein the container may experience an excessive buildup of internal pressure. The closure is equipped with a “blowout” portion which partially separates from the remaining closure portion if internal pressure exceeds a predetermined limit. The separation occurs at a line of weakness. The line of weakness is specially designed to withstand external, incidental pressure resulting from normal handling yet fracture in a controlled fashion should internal pressure exceed a predetermined amount. In this way inconvenience and possible hazard is avoided from a closure completely separating from the container from excessive pressure. | 11-11-2010 |
20120111863 | VERTICAL EXHAUST TYPE SEALING CLOSURE FOR SEALED CONTAINER - This invention relates to a vertical exhaust type sealing closure for sealed container, comprising: a closure body and a chute seat provided in the axial direction thereof; an air plug provided in the chute seat; a piston provided in the chute seat and above the air plug as well, an operating portion being combined at the upper end of the piston; when the operating portion is grasped to conduct continuous up-to-down reciprocating motion of the piston, opening and closing action of the air plug can be produced so as to extract the air contained in the sealed container. | 05-10-2012 |
20120273488 | VACUUM RECEPTACLE LID FOR EASY SEALING - A vacuum receptacle lid for easy sealing includes a lid body that closes and opens an inlet portion of a receptacle body provided with a space containing contents, and includes a valve installation hole formed at a part thereof, at least one air vent hole, and a packing installation groove which is opened downwardly in a C shape inside a rim thereof, a check valve that is provided a combining projection at a bottom surface of a body portion enclosing the air vent hole, is inserted into and combined with the valve installation hole, and exhausts air of the inside of the receptacle body via the air vent hole and blocks inflow of external air by enclosing, opening and closing the air vent hole, and a packing that is accommodated and installed at the packing installation groove, and includes an upper contact portion coming into contact with an upper surface of the packing installation groove, a lower contact portion coming into contact with the receptacle body, and an intermediate contact portion of which ends are connected to at least a part of the upper contact portion and the lower contact portion and which has a cross-section of a zigzag shape. | 11-01-2012 |
20130264341 | THIEF HATCH - Embodiments of the present disclosure are directed towards a venting hatch having a base configured to couple to a storage container, wherein the base comprises a central opening configured to be exposed to an opening of the storage container, a cap coupled to the base, a seal disposed between the base and the cap, and an actuating mechanism configured to exert a biasing force on the seal to bias the seal against an annular lip of the base, wherein the actuating mechanism is disposed on an exterior surface of the cap. | 10-10-2013 |
20150321806 | CHECK VALVE AND CONTAINER WITH CHECK VALVE - A check valve | 11-12-2015 |
20160000271 | CONTAINER LID FOR VACUUM SEALING HAVING LOCKING PARTS AND VACUUM-SEALED CONTAINER EMPLOYING SAME - Disclosed is a container lid for vacuum sealing which generates negative pressure in the internal space of a container, which is provided by covering the open upper part of a container main body, and seals same. An annular packing is mounted so as to go around the inner surface of a lid main body, and a check valve is mounted in the inner part of the outer surface of the lid main body. The check valve generates negative pressure in the internal space of the container by allowing air inside the container to flow to the outside but preventing outside air from flowing into the container when a pressure difference occurs between the inside and outside of the container. A plurality of self catching protrusions are provided respectively at a plurality of points on the edges of the lid main body, and a plurality of locking members are mounted respectively and pivotably in sections adjacent to the plurality of self catching protrusions. Each locking member comprises: self-locking protrusions which are press-fitted and coupled to the self catching protrusions in a closed state so that the locking members are not released; and main body-locking protrusions which prevent the container lid from being taken off from the container main body by being caught by the circumference of the opening part of the container main body or a main body catching protrusion, even if the container lid rises due to the expansion of the packing as a result of a decrease in the negative pressure generated inside the container. | 01-07-2016 |
20160031616 | FILTER CLOSURE - A closure is provided. The closure is configured to be coupled to a container having a sidewall extending along a longitudinal axis and defining an open end and an interior. The closure includes a sidewall. The sidewall includes an inner surface and an outer surface. The inner surface includes a coupling feature configured to couple the closure to the sidewall of a container. The closure includes an intermediate wall extending radially inwardly from the sidewall including a first vent aperture. The closure includes an upper closure portion including a second vent aperture. The closure includes a filter layer located between the upper closure portion and the intermediate wall. The closure is configured to prevent gas from travelling in a path generally parallel to the longitudinal axis from the first vent aperture to the second vent aperture. | 02-04-2016 |
