The jet button 10 of this aerosol container, on the chimeric bar S that is attached at aerosol container C, S opens not shown valve system by the pressing operation bar, thereby sprays the powder aerosol content that is made of for example solid state powder composition, oiliness composition, propellant etc.

The jet button 10 of this aerosol container is by the jet button main body 11 on the chimeric bar S that is attached at aerosol container C, constitute with vent component 21 on the jet part that is arranged on this jet button main body 11.

In the jet button main body 11 of the jet button 10 of aerosol container, be formed with the embedded hole 12 of chimeric bar S in lower central, its bottom forms coniform, thereby can easily carry out to the chimeric of bar S, form the circulation flow path 13 of the path that has the inclined plane that the upper end side wall portion tilts to injection direction the place ahead on the top of this embedded hole 12, the powder aerosol content of spraying from bar S imports to the circulation flow path 13.

And then, be formed with leading section in the pars intermedia side of the circulation flow path 13 of this jet button main body 11 and be cylindric outstanding protuberance 14, from the front end of this protuberance 14 between the circulation flow path 13, on injection direction, be formed with the access 15 of path.

The place ahead at the protuberance 14 of this jet button main body 11 is formed with open chamber 16, and vent component 21 is installed in this open chamber 16, and is fixed on the periphery of protuberance 14 in the mode in the place ahead of clogging access 15.

This vent component 21, form and roughly be with the round-ended cylinder shape, at its base section is that the base end part (access 15 sides) of separating part 22 is formed with the jet chamber 23 that the powder aerosol content is ejected into by access 15, and with the front end face (lateral surface) of this separating part 22 as jet face 24, this jet face 24 base section of round-ended cylinder shape (roughly with) is installed in the open chamber 16 of jet button main body 11 towards the place ahead (outside), and is connected to by medial extremity on the groove bottom of peripheral part of protuberance 14 and positions cylindrical portion.

With this, jet chamber 23 becomes the state that is formed with the space between the medial surface of the front end face of the protuberance 14 of jet button main body 11 and separating part 22.

Be formed with a plurality of outlets 25, for example, in the present embodiment, on circumference, equally spaced be formed with 3, separating part 22 between the jet face 24 of the front surface of aforementioned this vent component 21 of outlet 25 perforations becoming and the medial surface of jet chamber 23, thereby pulverized powder aerosol content.

In addition, outlet 25 is not limited to illustrated example, also can make to become 2 outlets, or further increases the number of outlet 25, or other configuration outside adopting on the same circumference.

And, each outlet 25 is made of with inlet portion 27 export department 26, in export department 26, be formed with the cone shape wide diameter portion 28 that on injection direction, enlarges, in illustrated example, only vent component 21 radial outsides in export department 26 are formed with the cone shape wide diameter portion 28 that only enlarges on emission direction, shown in Fig. 2 (a), half work of the outside becomes the taper seat of hole enlargement, and inboard half work becomes the barrel surface of same diameter.

Like this, by being formed in the export department 26 of the outlet 25 of vent component 21 that diameter becomes big wide diameter portion 28 on the emission direction full week, shown in Fig. 3 (b), just can expand the jet angle of each outlet 25, thus constriction, creeping chill and ejection sound when relaxing pulverized powder aerosol content etc.

Again, especially as shown shown in the example, only be formed with that diameter becomes big wide diameter portion 28 on injection direction at the radial outside of the export department 26 of vent component 21, the state that keeps same diameter is still made to become in the inboard, with this, shown in Fig. 3 (a), just can with the inboard relatively only the jet angle in the expansion outside and also nonoverlapping respectively mode make the jet mode of the content that sprays from each outlet 25 even, thereby constriction, creeping chill and ejection sound can further relax pulverized powder aerosol content etc. the time.

In the jet button 10 of the aerosol container that constitutes like this, do to become jet face 24 is installed vent component 21 and be assembled in state in the open chamber 16 of jet button main body 11 in advance as the outside.

Then, the mode that is embedded in the embedded hole 12 of jet button main body 11 with the bar S with aerosol container C links.

If under this state, push jet button 10, the down-pressed pole S of aerosol container, then not shown valve system is opened, powder aerosol content in the aerosol container C is sprayed, import to circulation flow path 13 by bar S after, be ejected into the jet chamber 23 of vent component 21 from thin access 15.

So aerosol content collides on the wall with thin access 15 opposed jet chambers 23, powder is pulverized and is finely particulate, and owing to be ejected into the wider jet chamber 23 from thin access 15, expulsion pressure weakens.

Like this, pulverize the powder aerosol content that has weakened for finely particulate, expulsion pressure, enter in the inlet portion 27 of a plurality of outlets 25 of separating part 22 in the place ahead that is formed on jet chamber 23, to spray object portion be on the human body etc. thereby be ejected into from export department 26.

Jet button 10 according to such aerosol container, because expulsion pressure weakens, and from a plurality of outlets 25 injections, so can prevent the diffusion of powder aerosol content or spray lip-deep 2 diffusions of object, can spray on the wider area that is attached to corresponding to the number of outlet 25 etc.

Again, can expand jet angle with the wide diameter portion 28 of the export department 26 of the outlet 25 that is arranged on vent component 21, can suppress to be accompanied by constriction that expulsion pressure caused and the creeping chill that sprays and produce, and can reduce to be accompanied by the sound (ejection sound) that sprays and produce.

And then, if only this wide diameter portion 28 is arranged on the radial outside of vent component 21, then the mode that can not overlap each other with the powder aerosol content of spraying from each outlet 25 is expanded jet angle, because content is not overlapping, can also further correspondingly suppress to be accompanied by constriction and the creeping chill that sprays and produce.

Again, in the jet button 10 of this aerosol container, the stream wall 29 of the inlet portion 27 of the outlet 25 of vent component 21, as shown in Figure 2, work becomes the tabular surface of following no ladder: the leading section that links to each other with export department 26 is carefully coniform, forms continuous barrel surface at its base end part.

With this, be ejected into the inlet portion 27 that powder aerosol content in the jet chamber 23 successfully imports to outlet 25, and can prevent the accumulation of adhering to of content by smooth stream wall 29, can prevent the obstruction of the outlet 25 that causes because of the powder aerosol content, when reusing, also can successfully spray.

And then, in the jet button 10 of this aerosol container, because between the medial surface of the front end face of the protuberance 14 of jet button main body 11 and separating part 22, be formed with jet chamber 23, the powder aerosol content temporarily is ejected in this jet chamber 23 from thin access 15, afterwards, be ejected into through outlet 25 on the human body etc., so have content to adhere to be deposited in the situation in the jet chamber 23, but because jet chamber 23 is done to become and can content be imported to minimum stream (minimum space) 31 3 outlets 25 from access 15, so can prevent the accumulation of adhering to of content as much as possible, can prevent the obstruction of the outlet 25 that causes because of the powder aerosol content, when reusing, also can successfully spray.

Again, in the jet button 10 of this aerosol container, because exist the powder aerosol content be ejected in the jet chamber 23 along the medial surface of separating part 22, be the situation that the front end face of jet chamber 23 flows down, thereby exist to stop up the possibility of the inlet portion 27 of adjacent outlet 25, so be formed with the inlet protrusion 32 that increases highlightedly in the periphery of the inlet portion 27 of each outlet 25.Each protrusion 32 that enters the mouth shown in Fig. 2 (b), figure (c), forms roughly U word shape from peripheral part to central part with certain height.

By such inlet protrusion 32, even there is the content that flows down from the inlet portion 27 of adjacent outlet 25, also can flow along inlet protrusion 32, with this, just be difficult to cross higher part, thereby can prevent that inlet portion 27 from being stopped up by content.

Similarly, in the jet button 10 of this aerosol container, because there is situation about flowing down along jet face 24 from the powder aerosol content of outlet 25 injections, thereby exist to stop up the possibility of the export department 26 of adjacent outlet 25, so be formed with the outlet protrusion 33 that increases highlightedly in the periphery of the export department 26 of each outlet 25.Each exports protrusion 33, shown in Fig. 2 (a), figure (b), forms roughly U word shape from peripheral part to central part with certain height.

According to such outlet protrusion 33, even there is the content that flows down from the export department 26 of adjacent outlet 25, also can flow along outlet protrusion 33, with this, just be difficult to cross higher part, thereby can prevent that export department 26 from being stopped up by content.

In addition, minimum stream 31, inlet protrusion 32, outlet protrusion 33 in the jet button 10 of this aerosol container, that be used to prevent to cause blocked this problem such as outlet 25 because of content, except like that 3 combinations being provided with shown in the example as shown, it is provided with respectively independently, perhaps, can suitably determine according to the proterties of content with wherein any 2 settings in combination.

Then, other embodiment of the jet button of aerosol container of the present invention is described by Fig. 4, the part identical with the above-mentioned embodiment that has illustrated used identical Reference numeral, omit its explanation.

In the jet button of this aerosol container, the formation difference of vent component 41 forms separating part 42 to jet chamber's 43 lateral deviations with putting, and with this, jet face 44 just becomes the state of depression.And the outlet protrusion 47 of the periphery of the export department 46 by being formed on outlet 45 outstandinglyly and higherly forms cylindric, the part of its highly high jet face 44 depressions of sening as an envoy to.

In addition, the formation of other of this vent component 41, promptly inlet portion 27, wide diameter portion 28, stream wall 29, minimum stream 31 and inlet protrusion 32 are identical with the vent component 21 that has illustrated.

Jet button according to the aerosol container of such formation, outlet protrusion 47 by vent component 41, even there is the content that flows down from the export department 46 of adjacent outlet 45, also can flow along columned, highly higher outlet protrusion 47, content just is difficult to cross higher outlet protrusion 47 parts more, thereby can advance to prevent more reliably that export department 46 from being stopped up by content.

Again, jet button according to this aerosol container, also can play the action effect identical with the jet button 10 of aerosol container, because expulsion pressure weakens, and from a plurality of jets 45 injections, so can prevent the diffusion of powder aerosol content or spray lip-deep 2 diffusions of object, can spray on the wider area that is attached to corresponding to the number of outlet 45 etc.

Again, can expand jet angle with the wide diameter portion 28 in the export department 46 of the outlet 45 that is arranged on vent component 41, can suppress to be accompanied by constriction that expulsion pressure caused and the creeping chill that sprays and produce, and can reduce to be accompanied by the sound (ejection sound) that sprays and produce.

And then, if only this wide diameter portion 28 is arranged on the radial outside of vent component 41, then can expand jet angle in the nonoverlapping mode of powder aerosol content of spraying from each outlet 45, because content is not overlapping, so can correspondingly further suppress to be accompanied by constriction and the creeping chill that sprays and produce.
