To a/ZZ whom it may cmwerm.

Be it known that .1, EwALD GOLTSTEIN, a subject of the Emperor of Germanyand a resident of Cologne, Germany, have invented certain new and v useful Improvements in Bottle-Caps, 4of which the following is a specification.

Hy invention relates to bottle caps such as rial, and has for its object to so construct the cap that it will be readily ontlopen l and also in such-amanner as to save certain valuable parts of the cap and revent their separation from the bottle or ot er receptacle to which the cap is applied. u Reference is to be had to the accompanying drawings in which Figure 1l shows the neck of a bottle with one forni of, my improved cap a plied thereto; Fig. Z is a cross section of anot er form of the cap showing its appearance before it is apsec'tional view of the neck of a bottle with still another form of my cap applied thereto; and Fig. 5 showsthe capof'Fig. 3 applied to a bottle. l I

.As illustrated in Fi suitable material suc 1. the cap consists of as aluminium, and

comprises an annular portion A which is' adapted to surround the bottle neck, and a removable central portionA A in the nature ofa disk which is so` connected with the annular ortion as tb facilitate separation therefrom. For this purpose'l provide at the upper edge of the annular portion an inwardly bent portion A7 resting on the end surface of the neck and the outer edge of the central portion A is also 'bent inward, thus forming a contraction or groove A2 which facilitates the use of a cutting tool, such as a knife. The groove also guidessuch knife as it is passed aroundthe cap since the edge of the central portion A- overhangs the inner edge of the portionTAT. Before the cap is applied, its ring-shaped portion A is straight,

after this portion has been slipped over the neck C of the bottle, which is provided with a rubber washer B located in a groove C, the annular portion A is nicked or pressed -inward at such groove, so as to force it into ln'this manner the cap is firmly connected With'the bottle. uWhen it is desired to'open the bottle,

`the central ortion Al is removed by cutting it away Wit a knife or other tool.

Among the advantages of my invention I desire to point out particularly the great ease of opening the bottle, as the removal of the central portion of the cap isy facilitated. Another advantage consists in the fact that the annular or surrounding portion A remains connected with the bottle and there` fore permanently protects the. washer B against injury bydirt, dust or light. The bottles which are returned to the brewery or bottling establishment still have the ring A.

and the'washer B upon them, and I thus save the said ring which, when made of aluminium as I prefer todo, is relatively valuable. The used. ring A would be removed at the brewery or bottling establishment and a complete new cap would be substituted, but the original washer may be used a number of times.

The cap shown in Fig. 2 differs from the one iirst described chiefly'by having the diameter of the removable portion or disk a equal to that of the annular portion a, or contraction a is similar to the voneshown i'nFigl.

- In Fig. 3 I have stiffened kthe removable portion of the cap by means of a separate disk D' whichis held by the contraction A2, the form of the cap being othe1wise'-the same as that in Fig. 1. Fig. 5 shows this .type of cap applied to a bottle. This strengthening disk may.' be of advantage in some cases to prevent injury to the removable up er portion of the 'ca which may be terme a sealing disk or sea ing portion. Iclaim: v1. The combination with a receptacle, of a cap having an annular portion surrounding the neck of the receptacle, and inwardly bent portion located' above said annular portion and resting on the end surface 'of the neck, and a sealing portion extending across the receptaclesmouth, and located above said inwardly bent portion and projecting out- 8o i The throat ICO wardlyso aste overhang the same and form IOS IIC
