To all whom it may concer-n,.- Y

Be it known that I, PAUL KIRSCEEN, ot'

Dresden, in the Kingdom of Saxony, German,

Empire, have invented certain new and usespecication, and for -which there have been obtained patents in Great Britain, No, 8,051,

dated March 29, 1897; in Switzerland, No.

14,237, dated March 8, 1897; in Sweden, No.

9,228, dated March 31, 1897; in thel German Empire, No. 99,280, dated February 23, 1897; in Russia, No. 1,545, dated January 16, 1899; in Austria, No. 4.8 2,085, dated April 12,1898, No. 9,981, dated October 29,

Y A device for closing bottles, flasks, cans, and the like embodying this invention come prises a cap ahixed to or forming a fixed part of the mouth or openingl of the bottle or other vessel and having an aperture, a cover itted to the cap to turn thereon and having an aperture corresponding with the aperture in the cap, and a loose imperforate closing-piece placed between the cap and cover and capable of turning with the latter to a position in which it closes the aperture in the cap or to a position in which it leaves the said aperture open for the purpose of allowing the contents of the bottle or'vessel to dow out in a stream or in drops..

The device may be constructed ofpvarious forms, as hereinafter described with reference to the accompanying drawings, and Aitmay be employed to tightly close not only bottles, cans, and the like containing liquids, but even those containing gases under pressure.

Figures l, 2, and 3 show the separate parts of one example of my invention, Fig. l representing a plan view of the cap and a section in the linem x, Fig. 2 a plan view of the cover and a section in the line y y, and Fig. 3 a side view of the movable closing-piece. Fig. 4. represents a central section of the said parts combined, Figs. 5, 6, 7, 8, and 9 represent 'central sections of as many examples illustrating modifications of the invention. Fig. 10 represents a plan and a central section of another modiiication.

`Referring rst to Figs. 1, 2, 3, and 4,' A is the cap, which is intended to be mounted and fixed with its cylindrical portion directly on the mouth or opening ofl the bottle or other vessel to be closed.Y This cap is provided with an Aeccentric aperture a.

B is the cover, provided with the two` apertures b and c and having its edge bent over the ilange of the cap in 'such a manner as to allow of the cover turning on the cap. Before the cover is placed into position there is inserted between it and the cap the loose im- Aperforate closing-piece Cl, which has a flat under surface bearing upon the cap and a convex upper surface projecting into the aperture b 4of the cover.

The loose imperforate closing-pieced needs to be only of such size that its under surface is capable of completely covering the aperture a in the cap A, whilei ts convex upper surface projects slightly through the aperture -bfof the coverpso that the cover whenV it is turned will carry the closing-piece with it.

In the position of the parts shown in Fig. 4 the 'closing-piece@ closes the aperture a. If the cover be turned so as to bring the aperture c in the cover over the aperture c, the contents of thebottle can then pass out.

From the above it will readily be understood that the lower surface of the closingpiece d, which is situated between the cover and the cap and is capable of moving with the cover, constitutes the closing element and in a suitable position relatively to the cap, because the smooth under surface of the closing-piece d will always follow up any bending 'of the surface of the cap, it being in-this connection immaterial lwhether the cover B is exactly parallel to that surface of the cap in which the outilow-aperture is provided. The smooth under surface will also always eiect a tight closure of the outflow-aperture a in the cap A, even when the closing-piece is made of other shapes, of which a few are shown by way of example in Figs. 5 to 10.

In Fig. 5 the upper surface of the piece d is shown recessed. Into 'this recess there ex-V tends a stud,projecting from the cover in such a 'manner that when the cover is turned the closing-piece d is moved over the outflowaperture c of the cap in order to ciose the jwill act as such each time when the coveris Y bottle or is moved away from said outlowaperture in order to open the bottle.

In Fig. 6 the closing-piece CZ is shown formed as a plate, which is held against the surface of thecap by means of a coiled spring. In Fig. 7 there is a similar plate (l, held by means of a leaf-spring. In both cases the plate CZ is moved by turning the cover B.

In Fig. 8 the closing-piece d is of triangular form in cross-section and enters with its apex or upper edge into a correspondingly-formed recess in the interior of the cover, which moves the closing-piece CZ With it in its rotation.

An elastic material-such as rubber,leather, cork,-&e.-may also be inserted between the eover and the plate-shaped closing-piece CZ, as shown inFig. 9.

If it is desired to have the outflow-aperture in the center of the closing deviee,lthis may be done, as shown in Fig. l0, by pivoting the part B', that carries the closing-piece d and which may be considered as of the cover B, eocentrioally aperture of the eap.

the equivalent to the outflow- In all the modifications the smooth flat under 'surface of the loose imperforate closing` piece d, moving with the cover B or its equivalentserves to close the outflow-aperture in the cap.

What I claim as my invention isE A device for closing a bottle, flask or other vessel, consisting of a cap affixed to the mou th or opening of lthe vessel and having an aperture, a Cover fitted to said cap and having a corresponding aperture, and a loose imperforate closing-piece attached to the cover between it and the cap and capable of turning Wit-h the cover to a position in vwhich it closes the aperture in the cap or to a position in Whiehit leaves the said aperture open, substantially as herein described.

In testimony that I claim the foregoing. as my invention I have signed` my name in presenee of two subscribing Witnesses.
