Abstract: A container for a product which off-gases has a container body with a base wall, sidewall and a large mouth at its upper end bounded by a lip and having an outwardly extending shoulder adjacent the upper end of the sidewall, and a foil seal which extends over the mouth and is adhered to the lip. The foil seal having a valve therein permitting gases in the container body to exit there through. A cap having a top wall and a depending skirt with an internal peripheral snap bead abuts the shoulder on the sidewall of the container body. The top wall of the cap has a depending flexible ring seal bearing on the lip and the inside surface of the cap has channels extending downwardly along the inside surface of the skirt. Gas pressure in the container body will cause the valve in the foil seal to release gas from the interior of the container body into the space in the cap and the pressure of the gas in the ring seal is deflected from the lip to allow the gas to flow thereby and outwardly in the channels in the cap.

Abstract: The invention relates to a cooling device, which comprises a cooling fan and a heatsink. The heatsink is directly attached to the heating element to absorb its heat and the cooling fan is disposed on top of the heatsink to dissipate the heat. The heatsink includes a central heat dissipation body and a plurality of fins extending from the periphery of the central heat dissipation body. The central heat dissipation body has a fully-sealed hollow chamber filled with a cooling liquid and disposed an agitator. The agitator is disposed a magnetic element, and where the magnetic element corresponds to the rotor of the cooling fan must have a magnetically-attracting and mutually-dragging device in operation. By way of the magnetic attraction between the rotor of the cooling fan and the agitator, a better heat dissipation effect is secured, the chamber remains a fully-sealed room, and the cooling liquid overflow issue can be ruled out accordingly.

Abstract: A container includes a box body having a housing trough, a jutting flange on the top that has buffer ridges on two ends, and an engaging member and a latch member extending outwards from two sides close to the frame rim of the jutting flange and an upper lid. The engaging member has a hook and the latch member has a sloped end. The upper lid has a clipping member and a latch plate having respectively a latch slot corresponding to and engageable with the hook and sloped end so that the upper lid can be anchored on the housing trough in an openable manner, and also can form a sealing condition with the box body. Thereby the upper lid can be lifted and opened to remove goods held in the box body by first hitting the buffer ridges to offset too much lifting force. The clipping member further has a latch flange on one end to lean against the outer side of the box body with one sloped surface of the hook holding the periphery rim of the upper cap.

Abstract: A method of seal locking together a preformed plastic molded top lid portion of a gas filler cap to a preformed plastic molded threaded base portion of a gas filler cap. The preformed top lid portion of the gas cap is locked to a stationary preformed threaded base portion of a gas filler cap by spin welding a lower extending tab of the top lid portion into a mating channel in the base portion together. The tab can be a circular rectangular tab having a step down inner edge and an indentation cutout on the lower surface of the lid portion between the tab and an exterior side wall of the lid portion, wherein the indentation cut-out provides a sacrificial break point upon impact and allows the exterior side wall of the top lid portion to break-off without breaking the locking seal between the tab and the channel for reasons of safety upon impact. The channel can be a circular with an angled inner wall.
