A threaded valve for an aerosol container. The threaded valve comprises a housing, a moving assembly disposed in the housing, threads suitable for threadable onward attachment onto a complementary neck of an outer container for an aerosol dispenser and a plurality of pawls and/or ratchets disposed on and extending from the housing. The pawls and/or ratchets allow onward rotation of the valve onto the complementary neck and impeding rotational detachment of the valve in a reverse direction.

A substance dispensing system including a first pressure vessel defining a first interior space; a first substance positioned in the first interior space; a first portion of a first propellant positioned in the first interior space; and a first portion of a second propellant positioned in the first interior space. At least 90 percent by weight of the first propellant is at least one of carbon dioxide, nitrous oxide, and combinations thereof. At least 90 percent by weight of the second propellant is at least one of nitrogen, argon, helium, oxygen, and combinations thereof.

Various implementations of the invention are directed toward a sanitizing door handle and/or components of such sanitizing door handle. Some implementations of the invention are directed toward a manual sanitizing door handle while some implementations of the invention are directed toward an auto-sanitizing door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto an exterior surface of the sanitizing door handle in connection with an operation of the door handle to sanitize the door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto a user's hand(s) in connection with an operation of the door handle to sanitize the user's hand(s).

A valve mechanism for a high-pressure spray can has a switching base, a first ball, and a second ball. The switching base has a first passage, a first suction port, a second passage, and a second suction port. The first passage has a first inclined inner wall surface. The first inclined inner wall surface extends obliquely toward a specific side from the top end to the bottom end of the first passage. The second passage has a second inclined inner wall surface. The second inclined inner wall surface extends obliquely toward the specific side from the bottom end to the top end of the second passage. The first ball and the second ball are respectively mounted in the first passage and the second passage and move along the first inclined inner wall surface and the second inclined inner wall surface to block the first suction port and the second suction port.

Plastic pressure container including a main body portion, a finish portion, and a closure assembly. The main body portion defines an interior space. The finish portion is unitary with the main body portion and defines a mouth in communication with the interior space. The finish portion has an inner surface, an outer surface and an upper rim proximate the mouth. The inner surface has an inner undercut defined therein proximate the upper rim. The outer surface has an outer undercut defined therein proximate the upper rim. The closure assembly is mounted to the finish portion in engagement with both the inner undercut and the outer undercut.
