MOUTH CLEANSING DEVICE Filed May 16, 1931 1; 1 0127? r.- HAW-drag Patented Aug. l, 1933 UNITED STATES PATENT orrlca 3 Claims.

The present invention has for its object a mouth cleansing device of the type in which a liquid dentifrice contained in a bottle or the like is atomized by means of carbon dioxide, which is introduced into the bottle or container from a steel bulb of the sparklet type containing carbon dioxide under pressure. In the known mouth cleansing devices of thi kind the bottle or vessel containing the liquid dentifrice is placed in direct communication with the interior of the sparklet bulb, when the-seal of same is pierced in the ordinary, manner, and these facts make it diflicult to regulate thepressure and at the same time a considerable part of the carbon dioxide is wasted without being utilized for its purpose.

The drawbacks adhering to the known devices of this type are avoided in accordance with the present invention, in accordance with which there is located between the sparklet bulb and the vessel containing the liquid dentifrice a hand operated shut off valve, which interrupts the connection between the sparklet bulb and the liquid completely, and is only open when the apparatus is used.

Further in accordance with the present invention the apparatus may be provided witha second shut ofi valve located in the usual manner between the vessel containing the liquid and the jet through which the spray is expelled, and this valve in accordance with the present invention is actuated by means of the same hand operated actuating device as the valve first mentioned.

Preferably both valves are opened by hand pressure on a common lever against the pressure of springs, which tend to maintain the valves in closed position, the opening device so adjusted as to first open the valve located between the vessel and the jet and then the valve between the vessel and the sparklet bulb, the closing of both valves taking place in the opposite order.

Further features of the invention will be pointed out in the following specification with reference to the drawing showing a vertical sectional View through a form of the invention.

The vessel 1 for the liquid dentifrice is made in the form of a double wall cylinder, the liquid being filled into the space between the two cylinder walls through a spout or filling opening not illustrated on the drawing.

In the inner cylinder 2 is placed a sparklet bulb 3, which is pressed'by means of screw 4 with handle 5 in the usual manner against a piercing needle 6 with a channel 7 for the carbon dioxide.

Said channel is closed at the top by means of spring actuated valve 8, which is tightened by means of a rubber packing 9.

The said rubber packing 9 serves as valve spring as well as tightening means, and as it will be notedthe tightening is increased when the packing is compressed when opening the valve.

When the valve is opened the carbon dioxide passes through conduit 10 into vessel 1 and hereby presses the liquid dentifrice through tube 11 to jet 12. Tube 11 is provided in the usual manner with a small hole 13, through whichgas may enter so as to produce a mixture of carbon dioxide and atomized liquid dentifrice.

The opening at the upper end of tube 11 is controlled by means of spring actuated valve 14, which is constructed in the same manner as valve 8.

The jet tube 12 is removably secured to the rotatable head 15, which may be turned about an axis perpendicular on the longitudinal direction of jet tube 12.

Valves 8 and 14 are actuated by means of handle 16, which is in the form of a bell crank lever, one arm of which engages both valves so as to first open valve 14 and then valve 8, whereby carbon dioxide is permitted to pass from bulb 3 to vessel 1 so long as pressure is exerted against handle 16.

What is claimed,

, 1. An atomizer comprising a container for the liquid to be sprayed, a top secured-to said container, a removable carbon dioxide bulb located within said container and below said top, means on said top for piercing said bulb, a conduit in said top part of which extends through said piercing means for connecting said bulb and said container, a spraying nozzle, a second conduit in said top connecting said container with said spraying nozzle, two separate valves located in said top controlling said two conduits, means for normally maintaining said valves in closed position and a single hand operated means secured tov said top for opening both of said valves in M0 sequence.

2. An atomizer comprising a double walled container providing a space between said walls for liquid to be sprayed, a top secured to said container, a removable carbon dioxide bulb located within the inner wall of said container and below said top, a projection upon said top for piercing said bulb, means within the inner wall of said container for forcing said bulb against said projection, a conduit in said top connecting said bulb and said liquid space, a spraying nozzle, a second conduit in said top connecting said spraying nozzle with said liquid space,- two separate valves located in said top controlling the said two conduits, resilient means normally holding said valves in closed position and manual means for opening both of said valves.

against said projection, a conduit in said'top connecting said bulb and said liquid space, a

spraying nozzle, a second conduit in said top connecting said spraying nozzle with said liquid space, two separate valves located in said top controlling the said two conduits, resilient means normally holding said valves in closed position and means including a pivoted'lever secured to said top for opening the valve controlling the conduit between the container and the spraying nozz1e first and then opening the valve controlling the conduit between the bulb and the container.
