| 20090045199 | CLUTCH OIL RESERVOIR CAP - A clutch oil reservoir cap according to an exemplary embodiment of the present invention including a head and a body may include an exhaust opening formed in the head for exhausting air, an intake hole formed in the head for inflow of air, and an operation valve disposed in the head, wherein the operation valve selectively opens or closes the exhaust opening and the intake hole according to fluctuation of pressure in a part below the operation valve. | 02-19-2009 |
| 20100282751 | SCREW CAP - The present invention relates to a screw cap ( | 11-11-2010 |
| 20110253721 | CONTAINER LID EVACUATION DEVICE - A storage container device that is sealed to provide a controlled atmosphere to protect stored items from moisture and/or oxygen. Such a storage container device includes a storage container and a lid, where the lid is sized to be secured to the storage container, either through compression fit, threaded attachment, or a combination thereof. The lid further includes a valve that can be secured to a vacuum pump to evacuate the fluid contents of the container. Additionally, the valve may be used to introduce an inert gas, such as argon or nitrogen, into the container to preserve its contents. A plurality of storage container devices may be stackable, and a spacer may be used to facilitate stacking if the location of a valve would otherwise impede stacking. | 10-20-2011 |
| 20110284542 | Fuel cap cover - A cover for a vented fuel tank cap comprises a cover body in which a cavity and a vent are formed. The vent may be built into the cap by drilling at an acute angle through a lower surface and an interior sidewall, and into the ceiling of the cavity. A hollow member extends from the ceiling into the cavity, allowing the cavity to remain in fluid communication with the vent. The exterior surface of the structure forms a barb for securing a flexible tube. The position of a moveable element within the cylinder, such as a ball, acts as a valve allowing air to enter the fuel tank through a slot when the cover is in place, while preventing loss of fuel if the tank assembly becomes inverted. The fuel cap cover features a low exterior profile, without protrusions, and the cover preferably has no articulated or detachable parts. | 11-24-2011 |
| 20120267372 | Plastic Closure with Enhanced Performance - A plastic closure embodying the principles of the present invention comprises a closure cap having a top wall portion, and an annular skirt portion depending from the top wall portion. The skirt portion includes an internal thread formation for threaded engagement with the external thread formation of an associated container. In order to facilitate high-speed application, and minimize the use of polymeric material, the closure is configured to exhibit a variation in retention force which decreases in a direction away from the top wall portion of the closure cap. | 10-25-2012 |
| 20130087564 | APPARATUS FOR OPENING AND CLOSING RESERVOIR - An apparatus for opening/closing a reservoir, capable of communicating the inside the reservoir with outside air and preventing oil stored in the reservoir from leaking to the outside, the apparatus including a cap coupled to an oil injection port of the reservoir storing oil and provided with an air passage connecting an entry positioned in a center of an inner surface of the cap to an exit positioned at an inner surface of an outer side in a radial direction of the cap to communicate with outside air, and a gasket provided between the inner surface of the cap and the oil injection port and provided in a center thereof with an air-passing hole to communicate the air passage with an inside the reservoir, wherein the air passage is connected in a way to pass through a position, which is spaced apart from the entry to the exit in a coaxial manner with respect to the entry, at least one time. | 04-11-2013 |
| 20160067147 | TRANSFER LID - A transfer lid for a fluid container, having an attachment collar for removably attaching the transfer lid to the fluid container, and an inner collar arranged generally concentrically with and spaced inwardly from the attachment collar, the inner collar having a vent opening such as a vent slot extending therethrough. | 03-10-2016 |
| 20160120343 | ANTI-SPRAY DRINKING BOTTLE - An anti-spray drinking bottle has a body, a lid, at least one check valve, a dividing mount and a guiding element. The body has a storage recess and a screwing section. The lid is detachably connected to the body and has a threaded segment connected to the screwing section, a buffering segment connected to the threaded segment and a buffering space formed in the buffering segment. The at least one check valve is mounted on the lid. The dividing board is connected to the lid, is mounted in the body and has a dividing board, a sidewall, an outlet pipe and an abutting segment. The guiding element is connected to the dividing mount, is mounted in the body and has an elongate straw tube connected to the outlet pipe. | 05-05-2016 |
