nrnYL-cnnonrnn TUBE.'

Application filed September 16, 1927, Serial No."218,961, and in Germany June 28, 1927.

tube by means of which,owing to its simpleV and novel construction, the jet can be directed without diiiiculty and without special inanipulations in any desired direction. n

lilith this object in view, the capillary tube Vcapillary outlet channels, one o1c which is connected to a pipe arranged in the tube, and the other one terminating freely at the junction of the neck andl the body of the ethyl chloride tube. v

This improved tube is efficient and desirable to dispense ethyl chloride which, when affected by the hand temperature, produces a vapor and pressure that causes the liquid to flow out of one or the other capillary outlet channel according to theposition in which vthe tube is held.

A form of construction ot an ethyl chloride bottle, according to the invention (without metal closure) is shown, by way of example, in the accompanying drawing in which Fig. 1 is a longitudinal section. l

Fig. 2 shows the capillary tube on larger scale in cross section on line A-B of Fig. 1.

The vessel 1 has an inner rising pipe 2, the upper end of which is a capillary channel 7 of a capilla-ry tube3 at the outlet end of the vessel. The capillary tube 3 has a second capillary channel 8, the inner end otV this capillary channel 8 communicating directly with the ethyl chloride tube or vessel 1 at the junction of the tube 3 with the body.

lVhen the tube 1 is held in the hand so that the mouth of the capillary tube 3 is upwardly directed, the heat from the hand causes vaporization so that a jet of ethyl chloride flows out through the rising pipe 2 and the capillary channel 7. The same is the case when the upwardly directed tube 1 is inclined to the right or llett up to an angle of 90. l

When the tube is turned so that the outlet i end of the capillary tube 3 is downwardly the capillary channel 8, the same being the case when the tube 1 is inclined downwardly to the right or lett at an angle up to 900. v f

W ith the hand gripping the tube 1, a full jet of the ethyl chloride will issue from 'one of the capillary channels.

lt is advisable to connect the lower end of the rising pipe2 to vthe bottom of the ethyl chloride tube and to provide a lateral hole 6 in the same nearthelower end. By this arrangement the possibility of breakage ot the rising pipe by jarring or hitting the tube 1 is cfmsiderably reduced and the whole device is made more stable.

lnthe position ot the tubel shown in Fig. l of the drawing the tube and the contents being heatedby the'hand, the ethyl chloride is vaporized more rapidly than it can flow out of the capillary channel 8, and this pressure, acting upon the upper end otthecolumn or' ethyl chloride will torce the liquid through the hole 6 into the rising pipe 2 and out in a jet through the capillary channel 7.

The outer end of the capillary tube 3 is leither closed 'by melting (for small-size tubes) or by any suitable form of closure.

The tube can be used for ethyl chloride and as lance-perfume and also for mixtures oi? ethyl chloride and other liquids possessing a low boiling point, for instance, methyl chloride, and the tube may have either a flat or round bottom.

1. A dispensing container forv ethyl chloride, comprising ay main tube, a rising pipe in said main tube, and a capillary tube integral with one end oi said main tube, said capillary tube having two capillary outflowl channels1 one ot said channels communicating with said rising pipe and the other directly with the,l interior of said main tube.

2. A dispensingcontainer for ethyl chlo ride, comprising a main containing tube, a rising pipe in said main tube integral with the bottom ot said main tube and having a lateral inlet opening for the ethyl chloride adjacent the bottom of the main tube, and a capillary tube at one end of said main tube, said capillary tube having two capillary youtflow channels, one of said Channels communicating with said rising pipe and the' other directly with the interior of said main tube. In testimony whereof I have hereunto set my hand.
