20100018971 | ANTI-LEAK DEVICE FOR TUBE CONTAINER - An anti-leak device for a tube container is disclosed, to have a predetermined amount of contents in the tube container be continuously extruded and then prevent more extrusion, and to prevent infiltration of external air. The anti-leak device includes a main body having a head with a tube outlets and a connection groove, and a leakage prevention unit having an opening and closing part, an insertion part and a fixed part. The opening and closing part is inserted in an inlet path of the insertion part. The insertion part is inserted in the fixed part having a discharge hole and engaged with the connection groove, thereby forming a movement space for the opening and closing part to reciprocate between the tube outlet and the insertion part. The opening and closing part directly opens and closes the tube outlet not to allow external air into the main body. | 01-28-2010 |
20110000910 | No-Spill Drinking Cup Apparatus - An improved no-spill cup construction and valve assembly. When not in use, an opening in the flexible material rests against a blocking element, sealing off the opening against the flow of liquid. The closed position provides an extremely secure seal against fluid leakage, such that inadvertent spills, such as by turning the cup upside down, are ineffective. The act of sucking at the cup spout creates negative pressure or a partial vacuum against the flexible material, lifting the opening off of the blocking element, and unblocking that opening. When the opening is unblocked, liquid can flow freely through the valve and spout. | 01-06-2011 |
20120318795 | Gasket for a Utensil for Cooking Food and a Utensil Provided With Such a Gasket - Provided is a sealing gasket for a utensil for cooking food under pressure, the utensil includes a vessel on which a lid is designed to be mounted; a sealing gasket interposed between the vessel and the lid for sealing the utensil in operation; and centering means designed to center the gasket relative to the vessel and to the lid. The sealing gasket includes a peripheral band and a peripheral under-band extending under the peripheral band and extending it, and centering means provided in or disposed in the gasket in such a manner that said centering means can come to be interposed between the lid and the vessel while the lid is being put into place on the vessel so as to form a centering abutment. The centering means being formed by a plurality of local extra-thickness zones, situated on the inside face of said peripheral under-band and designed to come into contact with the vessel. The utensil is a pressure cooker. | 12-20-2012 |
20130306632 | METHOD AND APPARATUS FOR REGULATING PRESSURE IN A CONTAINER - A method and apparatus for venting and compressing a fluid. The apparatus comprising a valve having a vent and a compressible element attached to the vent. The vent and the compressible element define a flow-through channel therein. The compressible element has an internal space adapted to be elastically compressed and expanded. The valve is further adapted to regulate a pressure in a container when a predetermined pressure is applied to the compressible element of the valve. | 11-21-2013 |
20140076894 | AIRTIGHT COVER - An airtight cover aims to cover an opening edge of a container and includes an upper rigid lid and an airtight flexible plate located below the upper rigid lid. The airtight flexible plate includes a sealing rim in contact with the opening edge and a central portion and a peripheral portion located respectively on an inner side and an outer side of the sealing rim. The sealing rim and upper rigid lid are interposed by a gap. When the airtight flexible plate contacts with the opening edge through the sealing rim to make the central portion continuously move downward, the peripheral portion is forced to warp upward, and the upper rigid lid presses the peripheral portion to bend downward. Hence the contact area between the sealing rim and opening edge increases, which can securely seal the container to meet requirements of usage. | 03-20-2014 |
20150096985 | SNACK CONTAINER - A snack container for holding food items. The container includes a main body and a lid coupled to the main body. The lid includes a first section having an interior rim defining an opening. The lid further includes a second section coupled to both the main body and the first section. The second section is affixed to the main body along a first portion of the second section and not affixed to the main body along a second portion of the second section. | 04-09-2015 |
20150360561 | FILLER CAP FOR FUEL TANK - Filler cap for fuel tank which can further prevent environmental pollution without releasing harmful gas evaporated from fuel in fuel tank and can improve fuel efficiency is provided. When vaporized gas is generated in fuel tank, inner pressure of fuel tank is increased to pressure for deformation strength prescribed to valve body or more, a central part of valve body enters into third space thereby causing deformation so to shorten outer diameter of valve body to form wrinkles, and in peripheral part of valve body are formed a portion contacting to pivot of cylinder main body when deforming and concave portion not contacting thereto, second space and third space are connected via space of this concave portion and air passage channel formed in wall surface forming second space to release excessive pressure to outside fuel tank thereby bringing pressure inside fuel tank to lower than the pressure for deformation strength. | 12-17-2015 |
220203200 | Float or gravity valve | 3 |
20120318794 | LEVER BASED GRADE VENT VALVE - A grade vent valve assembly includes a float moveable between a lowered position and a raised position. A lever is coupled to the float at a first end of the lever. The lever pivots about a fulcrum spaced from the first end in response to movement of the float between the raised position and the lowered position. The lever pivots between an open position when the float is in the lowered position, and a sealing position when the float is in the raised position. The lever seals an orifice when in the sealing position to block fluid flow through the orifice. | 12-20-2012 |

20120248110 | AIRTIGHT CONTAINER - An airtight container includes a jar, a cover, a sealing ring and a check valve. The cover includes an opening defined therein. The sealing ring is used to block a gap between the cover and the jar when the cover is located on the jar. The check valve includes a plug and a ball. The plug is fit in the opening and made with a chamber and a tunnel in communication with the chamber. The ball is used to contact the wall of the chamber when air tends to enter the jar via the check valve. The ball can however be lifted from the wall of the chamber by air leaving the jar. | 10-04-2012 |

20140183194 | CLOSURE SAFETY INTERLOCK WITH LOCKOUT PLATE FOR PRESSURE VESSEL - A closure safety interlock system is provided for a pressure vessel having a closure assembly with a primary locking system. The closure safety interlock defines a secondary locking system for assuring that the primary locking system may be opened only by following a proper sequence, thereby minimizing misuse of the primary locking system. The closure safety interlock includes a blocking member movable between an engaged position and a disengaged position for blocking movement of a primary lock when in the engaged position and until a release mechanism in the primary lock has been activated. A mechanism is provided for moving the blocking member from the engaged position to the disengaged position once the release mechanism has been activated. A locking plate is movable between a locked and closed position for prohibiting access to the blocking member and an open position for gaining access to the blocking member. | 07-03-2014 |
20150136770 | AIRTIGHT STORAGE CONTAINER - A container includes a container body, a lid member, a first seal valve and a second non-return valve. The lid member is superimposable on the container body to form a storage chamber in the container, and defines therein a first opening and a second opening The first seal valve is disposed on the lid member, normally seals the first opening of the lid member, and is operable to unseal the first opening of the lid member. The second, non-return valve is disposed in the second opening of the lid member to permit air to actively flow out of the storage chamber of the container body upon reaching a predetermined degree of pressure, and to prevent environmental air from being drawn into the storage chamber. | 05-21-2015 |
