Abstract: A heat insulated coffee carafe for placement at the brewed coffee outlet of a coffee maker is provided with a securely fitting lid through which the coffee passes directly into the carafe without removal of the lid. When the carafe and its lid are placed in the coffee maker, mutual pressure between the lid and the coffee maker causes seals in the lid to open and permits the coffee to enter the carafe without removing the lid and with a minimal loss of heat and coffee aroma. Removal of the carafe and lid from the coffee maker automatically closes the seals to retain the heat and aroma in the carafe for long periods of use. In another embodiment a positive drip-stop seal in the coffee maker is closed automatically when the carafe is removed, whereby dripping from the coffee maker is prevented. In a further embodiment, a drip-stop seal in the coffee maker and a seal in the lid are both opened when the carafe is installed in the coffee maker.

Abstract: A one piece tire valve adaptor for connection to an aerosol container including a base with a means for attachment to a mounting cup, a hollow tube connected to said base and including a spout for connection to a tire valve, and a flow passage extending from said first end to said second end.
