A pressure control device for pressure packaging based on a disc with fluid connection and a collecting basin, with associated stopper. The closing mechanism in the pressure control device is no longer based on a cylinder with a central opening in the separation wall and closing-off of the opening by means of a piston with stem. The proposal is extremely simple, compact and easy to assemble.

A container includes: a first tube assembly for dispensation of liquid from the container; and a second tube assembly for filling the container. A base of the container has a sloped floor with a collection point defining the lowest point in the interior of the container. The first tube assembly is positioned above the collection point. Each tube assembly includes a valve device coupled to a top of the container, and a linear tube extending from the top into the interior of the container. Each tube assembly includes a vented foot and a flexible section connecting the linear tube to the vented foot. The container may be constructed as a bottle having an upper ring and a lower ring attached thereto. The container may be configured for pneumatic or reciprocating mixing via the first tube assembly and second tube assembly.

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.
