It addition, in this condition, owing to the projection 69 of open-close lid 15 is configured at the lower position shown in Figure 26, therefore, as Shown in Figure 28, driven member 66 is configured in lower position under the elastic force effect of spring 68.Therefore, sealing member 67 is utilized to make up Nozzle for liquid 41 is closed such that it is able to prevent skin lotion from spilling from bottle 34.

And then, owing to open-close lid 15 is configured at lower position, therefore, as shown in Figure 19 and Figure 23, drive cam 61 to be joined Position placed below.Therefore, the cam follower 58 of bar 53 under the elastic force effect of spring 55 with drive cam 61 cam surface The first inclined-plane 611 than top side, top 613 in 610 engages, and by the active force of spring 55, bar 53 is configured at inner side Position and be held in this position.Therefore, slide block 51 is configured in the position of Figure 19 and Figure 21, the projection 52 on its top be positioned at by The downside of button 17.Therefore, button 17 is locked against pressing, and valve 25 keeps in closed mode, thus prevents carbonic acid gas Spray from gas bomb 22.

Therefore, it is possible to when preventing unexpected liquid to spill, carbonic acid gas ejection and carry when spraying or The portable cosmetology device of keeping.It addition, as it has been described above, cam follower 58 under the elastic force effect of spring 55 with drive cam 61 The first inclined-plane 611 retreated from top 613 engages, and therefore, the open-close lid 15 of closed mode is acted on the resistance towards opening direction Power, open-close lid 15 is kept in closed mode by this spring 55.Therefore, it is possible to avoid open-close lid 15 when carrying portable cosmetology device Such as in handbag, imprudence is mobile to this situation of opening side.It addition, it can be avoided that when the hand-held open-close lid 15 of user The part of main body side hangs down because conducting oneself with dignity thus open-close lid 15 becomes this situation of open mode.

When the skin lotion in bottle 34 is sprayed, pull-up open-close lid 15 as shown in Figure 2.When so operating, as shown in figure 27, Driven member 66 resists the elastic force of spring 68 and is lifted, sealing member 67 at skin lotion nozzle 41 upward away from, thus change Adornment nozzle for liquid 41 becomes open mode from closed state.

It addition, as shown in Figure 20 and Figure 24, by driving the rising of cam 61, cam follower 58 is more overdrived cam 61 Top 63, in other words cross stop (dead point), and to driving the second inclined-plane 612 side shifting of cam 61.Due to Two the most past downside, inclined-planes 612 retreat the most laterally, and therefore, spring 55 cam follower 58 applied is relative to driving cam 61 Face contact power die down, thus stop the hollow of resistance opened of open-close lid 15, and, by the cam effect on the second inclined-plane 612 The power-assisted brought is also carried out effect such that it is able to making open-close lid 15 move towards opening side with slight force, wherein, above-mentioned driving is convex Wheel 61 is rising based on open-close lid 15 and rises.It addition, under the effect of spring 55, bar 53 is outside along with the second inclined-plane 612 Side rotates, and therefore slide block 51 moves to the second position of Figure 22.Therefore, protruding 52 keep out of the way from the position of locking press button 17, thus Become the state being operable to button 17.

Therefore, when pressing the button 17 in this condition, valve 25 is opened, and sprays in gas bomb 22 from gas nozzle 24 Carbonic acid gas.Therefore, the peristome of skin lotion nozzle 41 becomes negative pressure, and the skin lotion in bottle 34 is pumped out, from skin lotion The skin lotion of nozzle 41 becomes water smoke under the effect of the jet flow of carbonic acid gas, and this water smoke is sprayed to outward from ejiction opening 18 Portion.Therefore, it is possible to provide skin lotion for making up.

Now, as shown in Figure 6, Figure 7, the bore of gas nozzle 24 is more than the bore of skin lotion nozzle 41, due to skin lotion Nozzle 41 is positioned at the spray stream range 45 from gas nozzle 24, produces drop the most hardly and sprays mist.Therefore, Can cosily use aerosol apparatus.

When spraying makes open-close lid 15 decline after terminating, the projection 69 shown in Figure 27 is made to decline on the contrary with said sequence, profit Driven member 66 is made to decline with the elastic force of spring 68.Therefore, skin lotion nozzle 41 is sealed by sealing member 67.Further, since Figure 20 institute The driving cam 61 shown declines, and therefore, cam follower 58 crosses above-mentioned top 613, i.e. stop from the second inclined-plane 612, to One inclined-plane 611 moves and is held in this position.Therefore, bar 53 is moved into the position of inner side, slide block 51 carry out sliding and to The primary importance that button 17 is locked as pressing is moved by its projection 52.Therefore, as it has been described above, open-close lid 15 is applied towards Closing the resistance in direction, when open-close lid 15 crosses stop, this resistance diminishes, and, by the cam effect on the first inclined-plane 611 Open-close lid 15 is acted on power-assisted downward such that it is able to make open-close lid 15 move to closed position with slight force.Then, when When open-close lid 15 arrives this closed position, owing to cam follower 58 cannot be directed away from the direction at top 613, i.e. outside the most extremely On first inclined-plane 611, therefore open-close lid 15 is prevented from towards the movement of opening direction.Then, described above court in this condition To opening direction, open-close lid 15 given strong resistance, thus open-close lid 15 is remained off state.Therefore, it is possible in preventing Carry under the state that adornment liquid spills or keeping aerosol apparatus.
