Abstract: A vineyard wire hanger configured to be releasably and adjustably mounted on a grape stake for supporting a vineyard or trellis wire. After installation of the hanger, the trellis wire may be tensioned without requiring any of a plurality of the hangers to be loosened, removed, or otherwise disturbed. The hanger includes a bracket configured to be mounted on a conventional grape stake. The bracket defines a central portion configured to substantially encompass a portion of the stake and a pair of terminal ends that are disposed parallel to each other. A wire receiving member defining a central opening is received between the terminal ends of the bracket. A portion of the central opening is exposed above the bracket terminal ends for loosely receiving the trellis wire. A bolt is received through cooperating openings defined by each of the bracket terminal ends and through the wire receiving member central opening to dispose each member in a fixed relative position.

Abstract: A sealed storage container includes a large storage compartment and a smaller cartridge chamber near the bottom of the storage container for a carbon dioxide gas cartridge. The cartridge chamber communicates with the storage compartment via a piercing orifice mechanism. The mechanism pierces the carbon dioxide gas cartridge when the cartridge is loaded into the cartridge chamber and pushed into the piercing orifice by a closure plug. When the cartridge is pierced; the carbon dioxide gas flows into the storage compartment and displaces the air in the storage compartment. The displaced air is exhausted through a small exhaust orifice near the top of a side wall of the storage container. When a sufficient amount of air is displaced, the exhaust orifice is sealed with a pipe plug.
