No. 388,227 Claims priority, application Japan, Nov. 7, 1963, 39/ 24,410 1 Claim. (Cl. 141-3) This invention relates toa rechargeable portable aerosol container.

Heretofore, aerosol containers are so constructed that it is impossible to recharge them with an aerosol. It is therefore unreasonable to provide a small-sized aerosol container. Thus the generally available aerosol container is not handy to carry in spite of the extensive demand of carrying such an aerosol as toilet and medicinal goods and the like.

One object of this invention is to provide a small-sized ae-rosol container which is facilitated to carry it.

Another object of this invention is to provide an aerosol container which is rechargeable with the aerosol from a master vessel when the aerosol container becomes empty or half empty.

In accordance with one aspect of this invention, there is provided a rechargeable portable aerosol container f-or toilet and medicinal goods and the like, comprising a valve means in the top of it and a manually workable gas expelling means in the bottom thereof, the valve means being adapted to engage with a blow out pipe of a master vessel. When the aerosol container is held in the upside down position and the valve means is engaged with the blow out pipe of the master vessel, it is possible to recharge the aerosol container with an aerosol contained in the master vessel under pressure by operating the gas expelling means manually.

The invention will be better understood and other objects and additional advantages of the invention will become apparent upon perusal of the following description taken in connection with the drawings, in which:

FIG. 1 is a vertical axial sectional view of an aerosol container embodying this invention;

FIG. 2 is an enlarged explanatory view similar to the upper half thereof;

FIG. 3 is also an enlarged explanatory view similar to the lower half thereof;

FIG. 4 is a cross sectional view taken along lines IIII-IIII of FIG. 3; and

FIG. 5 shows the operating parts in the recharging position.

Referring more particularly to the drawings, the preferred embodiment of this invention will now be described; however, this description will be understood to be illustrative of the invention and not as limiting it to the particular construction shown and described. An aerosol container 1 is made of a synthetic resin which is rather small-sized so as to facilitate to carry. Various appearances may be given to the aerosol container. A valve means is provided in the top part of the wall of the aerosol container 1. The valve means itself has a well known construction. It is necessary that the valve means is provided with a suction pipe 3 which is extended inside the aerosol container 1 down to the proximity of the bottom wall thereof. The -bottom end of the suction pipe 3 is formed into an oblique opening 3' so as to facilitate to expel gas. Alternatively, radial small perforations may be provided through the lowermost part of the wall of the suction pipe 3. A jetting means 4 is engaged with the valve means detachably in a well known manner. For recharging operation, the jetting means 4 is removed from the aerosol con- 3,366,148 Patented Jan. 30, 1968 lice tainer 1 turned upside down and the valve means is inserted into a blow out pipe a of a master vessel A. Alternatively, an attachment is provided to connect the Valve means with the blow out pipe a.

The valve means and the jetting means 4 therefor are well known. Now an embodiment thereof as shown in the drawings will be explained. The aerosol container 1 has a top opening which is covered by a cover 9 which is explained hereinafter. A tubular valve chest 7 is arranged axially in the top opening, which has an annular flange 8. The bottom surface of the periphery of the annular flange 8 is arranged on the top of the wall of the aerosol container 1, a ring elastic packing 5 being provided therebetween. Another ring elastic packing 6 is provided on the top surface of the annular flange 8 on which the cover 9 is placed. The cover 9 is adapted to cover the ring elastic packing 6, the peripheral part of the annular flange 8, and the peripheral edge of the ring elastic packing 5, and further extended downwards along the outer surface of the top part of the aerosol container 1 so as to engage with an annular neck 10 formed between the top part and the middle part of the outer surface of the aerosol container 1. By means of securing the skirt of the cover 9 to the annular neck 10, the cover 9 serves for holding the tubular valve chest 7 in place.

The ring elastic packing 6 is a thick one so as to engage snugly with a neck of a tubular member 2 which has a radial passage 12 in the neck so that the ring elastic packing 6 serves for closing the radial passage 12 normally. The tubular member 2 is provided also with an axial passage 13 which is extended downwards from the top of the tubular member 2 to the inside of the neck of the tubular member 2. The bottom of the tubular member 2 is not penetrated by the axial passage 13 which is connected with the radial passage 12. The valve chest 7 is provided with an inside shoulder 14. A coil spring 15 is compressed -between the shoulder 14 and the bottom of the tubular member 2 so as to force the latter upwards normally. Under the shoulder 14 the suction pipe 3 is fixed to the valve chest 7.

The aerosol container 1 has a raised bottom 16 so as to form a recess. The central p-art of the recess is protruded upwards as a tube which has a bulkhead 22 in the midst of the height. An exhaust pipe 18 is adapted to pass through the central hole of the bulkhead 22 vertically slidably and provided with two

radial passages

20 and 21. An inside disc 23 is arranged above the bulkhead 22 and secured to the top of the exhaust pipe 18 so as to blind it above the radial passage 21. An annular elastic packing 24 is provided between the inside disc 23 and the bulkhead 22. An operating disc 17 is arranged in the recess and secured to the lower end of the exhaust pipe 18 so as to blind it under the radial passage 20. A coil spring 25 is compressed between the bulkhead 22 and the operating disc 17 so as to force the latter downwards normally. Thus an exhaust passage is provided when the operating disc 17 is pushed up, which extends through the clearance around the inside disc 23, the radial passage 21, a vertical passage 19 inside the exhaust pipe 18, the radial passage 20, the recess, and the clearance around the operating disc 17. When the operating disc 17 is released, the communication is blocked at the outer end of the radial passage 21 and the lower surface of the inside disc 23 by the annular elastic packing 24.

In operation, when an aerosol contained in the aerosol container 1 is to be jetted for use, the jetting means 4 is pushed down whereby the tubular member 2 is pushed down into the valve chest 7 against the action of the spring 15. Then the ring elastic packing 6 is deformed so as to release the outer end of the radial passage 12 to communicate the inside of the aerosol container with the atmosphere through the suction pipe 3, the inside of the valve chest 7, the radial passage 12, the axial passage 13 and the jetting nozzle of the jetting means 4. This communication is blocked by the restored ring elastic packing 6 when the jetting means 4 and the tubular member 2 is released.

In recharging operation, the jetting means 4 is detached from the tubular member 2 so as to expose the top end of the axial passage 13. The aerosol container 1 is held in the upside down position and the top of the tubular member 2 is inserted into the blow out pipe a of the master vessel A. Alternatively, an attachment is employed between the tubular member 2 and the blow out pipe a so as to connect the two fluid-tightly. Then the operating disc 17 is pushed inwardly manually so as to communicate the inside of the aerosol container 1 with the atmosphere. By virtue of the communication, the pressure in the interior of the aerosol container 1 is held lower than that in the master vessel A so as to make the recharging possible,

easy and quick. In addition, by virtue of the arrangement of the suction pipe 3 extended to the proximity of the bottom of the aerosol container 1, it is prevented from any leakage of the aerosol contained in it when the operating disc 17 is pushed in the inverted position of the aerosol container.

While a particular embodiment of the invention has been illustrated and described, modications thereof will readily occur to those skilled in the art. It should be understood therefore that the invention is not limited to the particular arrangement disclosed but that the appended claim are intended to cover all modications which do not depart from the true spirit and scope of the invention.

What is claimed as new and desired to be secured by Letters Patent of the UnitedStates is:

1. A method of recharging a portable aerosol container with such an aerosol as toilet and medicinal goods and the like, comprising steps of removing a detachable jetting means capped on said aerosol container so as to expose a tubular member provided in the top of said aerosol container, inverting said aerosol container on a master vessel containing said aerosol under pressure, of connecting said tubular member with a blow out pipe of said master vessel, operating a workable gas expelling means provided in the bottom of said aerosol container so as to expel gas contained in said aerosol container whereby the pressure inside said aerosol container is kept lower than that inside said master vessel to carry the recharging operation into effect, removing said master vessel from said aerosol container, restoring said inverted aerosol container to its original position, and again capping said aerosol container with said jetting means.
