Problems solved by technology

However, since the spout is small, the resistance applied to the contents in the vicinity of the spout is large, the flow velocity of the contents near the spout is reduced, the flow is greatly disturbed, and it is directly discharged in a rod shape.

Abstract

A nozzle hole mechanism (10) is provided with a nozzle hole (28) which ejects a concentrate into the atmosphere, a swirl chamber (30) which supplies the concentrate to the nozzle hole (28), and a path (27) which supplies the concentrate to the swirl chamber (30). The diameter of the nozzle hole (28) is 0.2 mm or less, the length of the nozzle hole (28) is in the range of 0.05-0.3mm, and the swirl chamber (30) and the nozzle hole (28) are located on the same axis. The swirl chamber (3) is equipped with a front section having a solid cylindrical shape, which communicates with the nozzle hole, and a rear section having an ring shape. The nozzle hole mechanism is configured in such a manner that the concentrate is supplied to the rear section (30a) and discharged from the nozzle hole (28) via the front section (30b). The configuration enables the nozzle mechanism to spray fine particles over a wide area using small spray amount.

Description

technical field [0001] The present invention relates to spout mechanisms. Specifically, it relates to a nozzle mechanism attached to an injection member of spray products such as atomization products and pump products. Background technique [0002] For products that pressurize and discharge the content (stock solution) in a container, such as atomization products and pump products, there is known a nozzle mechanism that discharges (sprays) the discharged content in the form of a fine mist. [0003] Patent Document 1 discloses a nozzle mechanism for atomized products including a mechanical break mechanism in which a conical swirling chamber is provided inside the nozzle. The spout mechanism has a spray groove formed in contact with the outer peripheral edge of the swirl chamber, and the content is introduced into the swivel chamber through the spray groove. Therefore, the contents are sprayed out from the nozzle port in a state of swirling in the swirling chamber. Thereby,...
