(Cl. 299-95) This invention relates to hand apparatus, more Figs. 3 and 4 are cross-sections through arparticularly for medicinal and dental purposes, rangements (the head parts being omitted), in

The sparklet bulb is mounted as to constitute a single apparatus capable of within a casing e which is screwed onto the head being held in the hand and conveniently applied g of the appartus. At first, as shown in Fig. 2,

In known devices of this kind the whole quanpiercer h is provided within the head g, said tity of pressure medium, immediately after the piercer being adapted to penetrate into the seal sparklet bulb had been pierced, had been forced of the bulb d. The piercer h is provided with into the liquid container and, when opening the bores which inside of the head g of the appaoutlet had escaped very rapidly and completely ratus merge into the pasage a leading to the 70 through the nozzle, thus producing an effect liquid container i. which had lasted only fora few seconds. In con- At the n of h pa a. wh re it enters tradistinction to this, the present invention is the liquid con a 1111B Screw h is inserted, the characterized in that throttling means are interthreaded pa O which has a longitudinal o ve posed in the passage leading from the sparklet 0, through which the gas must flow in order to 75 bulb to the liquid container. The characteristic reach t e l quid container 2'. feature of the invention thus consists therein, Pressure d u a qu p through e that the relatively small quantity of the pressure siphon tube and its head is through an outlet medium contained in the bulb is consumed in an Valve I which is Operated in known manner y 5 economical manner to last over an extended pethe trigger lever e m x u e pa ses thence 80 rigd At the same time the contents may be through the passageninto the atorniz-ing 1102218 0.

the passage acts as a throttling device. I claim: I Fig. 2 shows a detail. 1. An atomizing apparatus for mouth and denill! tal purposes, comprising in combination a receptacle of such a size as to be adapted to be held in a hand; another receptacle smaller than the first-mentioned receptacle and adapted to hold a fluid under pressure; an attachable and detachable head on said first-mentioned receptacle and so designed'as to allow of connecting the two receptacles with one another and having two passages, of which one is adapted to establish a communication between the interior of said two receptacles; an atomizing nozzle also projecting forth from said head and being connected with the interior of the first-mentioned receptacle by the other passage of the said head; an outletvalve in this other passage; a screw inserted into the first-mentioned communication where this latter terminates into the said first-mentioned receptacleand having in its threaded portion a longitudinal groove for throttling the flow of the fluid under pressure according to the position of said screw, this latter being independent of said outlet-valve.

2. An atomizing' apparatus for mouth and dental purposes, comprising in combination a receptacle of such size as to be adapted to be held in a hand; another receptacle smaller than the first-mentioned receptacle and adapted to hold a fluid under pressure; an attachable and detachable head on said first-mentioned receptacle and so designed'as to allow of connecting the two receptacles with one another and having two passages, of which one is adapted to estaban outlet-valve in this other passage; a threaded member inserted into the first-mentioned passage and having a longitudinal groove for throttling the flow of the fiuid under pressure according to the position of the threaded member, this latter being independent of said outlet-valve and means for turning said threaded member from the outside of the first-mentioned receptacle. I

3. An atomizer for dental and medical uses comprising a sealed receptacle containing a medium under high pressure, a liquid container and an atomizing nozzle, means for securing the receptacle in fluid-tight relationship to' the liquid container, means for unsealing the said receptacle and for providing a passage connecting the interior thereof with the interior of the liquid container, means arranged in said passage and partly obstructing the same and having means whereby the degree of said obstruction may be set to a proper value to cause the pressure medium to-escape from the receptacle 'at any desired, pre set, suitably low rate of'fiow, va tube extending from the interior of the'container to the nozzle and a manually controllable valve arranged in said tube.
