Abstract: An easy-to-open and optionally resealable beverage can end provides opening by pressing downward. An actuator lies flat initially to conform to stackability requirements, but is readily repositionable to a ready-to-open state. In the ready-to-open state a planer surface of the actuator or tab is at a substantial angle to the can's top. A rigid body is interposed between it and the can's tear panel. The actuator is secured to the can top. Downward force ruptures the tear panel, opening the can. Using a wide actuator, a shallow protrusion on the actuator enables gas-tight resealability of a can opening. The shallow protrusion has an interrupted helix and fits into the can opening. Providing tab attachment via a radiused slot allows the small degree of rotational movement needed for the helix to be turned and pull the actuator bottom sealingly abutted proximate to the perimeter of the opened area.

Abstract: A universally installable climate control system for aftermarket installation in a motor vehicle which includes a heater valve which is controlled by the system and is connected in the supply line to the heater core of the originally installed heater/air conditioner. Additionally, a closed loop climate control system is employed which renders the system transparent to the type of motor vehicle in which it is installed, since the closed loop system ensures that a desired passenger compartment temperature is achieved substantially independent of the operating characteristics of the motor vehicle.
