ZbaZZwhom it may concern.

Be it known that I, ALBERT Hmvxrwu, a citizen of the United Kingdom of Great Britain and Ireland, and resident of 120 Harrow road, Leytonstone, Essex, England, have invented certain new and useful Improvements in Nozzles for Bottles, Tubes, and the like, of which the following is a. specification, such as will enable others skilled in art to which it appertains to make and use the same.

This invention relates to closing devices or stoppers, for capsules, ampoules, bottles, flasks, glass tubes and the like and while ap plicable to these articles for use with various fluids such as scents and the like is especially designedfor use with flasks or tubes containing volatile liquids such as ethyl chlorid, chloroform, ether and other medicinal fluids.

The chief object of the invention is to provide means whereby the closing device can be readily attached and detached without using cement or other binding or holding agent.

The invention may be broadly described as consisting in so fashioning or making the end of the bottle, flask, tube or other fluid container and also the closing device that the latter may be fitted to the former by simply pushing it into position and in providing means by which when the closing device is in place it will be held from accidental removal or displacement in either or both lengthwise and sideward manner.

In carrying the invention into efi'ect the closing device is so made that it will, in spring-like manner inclose projections on the bottle or flask, the grip of the said device being sulficient to hold it in position against any accidental displacement but not sufficient to prevent its intentional removal.

I will now describe the invention with reference to the accompanying drawings in which examples only are shown.

Figure 1 represents a flask or tube a of well known form except so far as my invention is concerned. This tube is fitted with a stopper or closin device of a type I have long used but which is specially adapted or constructed to fit the outlet or capillary end of the tube.

Fig. 2 is an enlarged view of the upper part of Fig. 1 and shows more detail.

Fig. 3 is a side view of Fig. 2.

Figs. 4: and 5 show two views of the upper or C(lrapillary end of the tube shown in Figs. 2 an 3.

Specification of Letters Patent.

gigs. 6 and7 showa modified form of tube an l i Figs. 18 and?) illustrate a modification.

Referring to Figs. 1 to 5 the flask or tube a is providedwith a spherical protuberance b hereinafter called the ball and two side protuberances c 0 hereinafter called theribs. The closing device has a spring controlled lever-stopper (Z mounted upon a sleeve or cap 6. The stopper (Z is adapted under pressure of spring 7, to close the capillary or fine tube 9 but may be lifted therefrom by pressure on the lever h. The sleeve has in this example two opposite openings 2' i and two opposite openings or slits y These slits allow for some relative spring movement of the sides.

or parts in which openings 2' 11 are made. This spring movement is sufiicient to allow the sleeve to be pushed down over the tube 9 so that the openings 2' 2' will receive opposite sides of the ball I) and grip upon same sulficiently to hold the sleeve against lengthwise accidental movement. When the sleeve is pushed into place the ribs 0 0 enter the slits y" j and prevent lateral or rotary movement of the sleeve around the tube 9. It is thus only necessary to push the sleeve into its correct position to hold it in place at the same time not preventing it being pulled off when it is desired to remove the closing device, for refilling, exchange or other such purpose. Instead of having ribs 0 0, depressions such as it 70, Figs. 6 and 7 can be provided in the sides of the ball and the sleeve may have corresponding inner ribs to fit into the depressions. The ribs or some other part of the sleeve would be slit to permit of the springlike movement above referred to.

If it is preferred the ball and the ribs can be made in the form of a metal cap such as 1 shown in Figs. 8 and 9. In this case the cap is permanently secured to a bottle, flask or tube with cement or other suitable adhesive. A ring or washer such as m Fig. 2 may be employed to center the tube 9 correctly in the sleeve 0.

A receptacle for liquids having a neck provided with a discharge opening, the root of the neck being spheroidal, longitudinal ribs on said spheroidal portion, a sleeve fitting over said neck having openings which engage the spheroidal portion and slots which engage said ribs whereby said sleeve is prevented from accidental displacement either longitudinally or rotarily, a lever pivotally mounted upon the sleeve, stopper thereon and spring means adapted to close the stopper over said opening.

In Witness whereof I have hereunto set my hand in presence of two Witnesses.
