Jet button for aerosol container

Abstract

A jet button (10) for an aerosol container (C) has a fit hole (12) to be fitted on a stem (S) of the container, a jet button body (11) in which a communication passage (15) communicating with the stem (S) is provided, and a nozzle member (21) attached so as to close the communication passage (15) of the jet button body (11) and provided with discharge openings (25). The nozzle member (21) is provided with the plural discharge openings (25), and diameter-expanded portions (28) expanding in a jetting direction are formed at exit portions (26) of the discharge openings (25). When aerosol contents are jetted by pressing the jet button body (11), the contents are introduced from the communication passage (15) into the nozzle member (21) and jetted with a reduced jetting pressure from the discharge openings (25) having the diameter-expanded portions (28) expanding in the jetting direction.

Description

technical field [0001] The present invention relates to a spray button of an aerosol container, which can prevent the diffusion of the content and spray the content to a wide area, can suppress the cold feeling accompanying the spray, and can prevent the clogging of the content, especially Suitable for spraying of powder aerosol contents. Background technique [0002] In powder aerosol products such as antiperspirants and deodorants, the content of powder and oily ingredients, etc., and the propellant are filled in the aerosol container, and the aerosol container is sprayed by operating the spray button of the aerosol container mounted on the rod. The pressure of the agent sprays the content onto the human body, etc., and makes the powder adhere to the skin, etc., and is used. [0003] As a spray button for spraying such a powder aerosol product, if a normal spray button is used, the powder is sprayed radially and spreads widely, and due to the high spray speed, secondary d...

AI Technical Summary

Problems solved by technology

[0008] However, the powder aerosol press button 1 of the former patent document is suitable for spraying to a very narrow range to make the powder adhere, but if the powder is to be adhered to a certain extent, the nozzle 4 must be enlarged. However, if the injection path 5 is enlarged, the problem of diffusion of the content and poor sprayability will occur

[0009] On the other hand, for the nozzle 6 of the latter patent document, because it is possible to expand the spray range and prevent diffusion by spraying from a plurality of spray holes 9 into the closed space formed in front of the concave surface 8, it is used as a hair restorer or the like. It is suitable when a massage effect is required, but if it is applied to an antiperspirant as a powder aerosol product, since the spray distance from the spray hole 9 to the spray site is short, there are the following problems: use The user will feel the strong pressure of the propellant and the strong cold feeling caused by the propellant, so the feeling of use is very bad

[0010] Again, there is the following problem: because a plurality of injection holes 9 are open on the concave surface 8, the injected content will flow down along the concave surface 8, and the injection holes 9 will be blocked, so that it cannot be used again smoothly.

[0011] Furthermore, there is also a problem of ejection sound in one of the usability of aerosol products, and it is desired to develop an ejection button that makes the ejection sound as small as possible.
