For closing the neck 17 The body 6 of the cap has an opening exthe ball valve 12 is swung from the left to tending centrally therethrough and provided the right in Figure 2 so that-the passage 15 :4, preferably for a portion of its length with thereof will be disposed somewhat obliquely 9 far as we are aware, receptacle caps employwith respect to the bore of the neck 17 so that a wholly solid portion of the ball valve 12 bridges or closes the bore of the neck.

As before stated and as is thought apparent, our improved cap may be used 'without altering the constructionof the mouth of the bottle to the extent of forming a seat such as the seat 18 herein shown, with the result that our vimproved cap is susceptible to use on many well known types of flexible tubes, bot tles and similar receptacles without requiring any alterations in the construction of such receptacle nor requiring any material alteration or departure from the principles of our invention other than for example a substitution of means such as slots and lug means in lieu of screw threads for effecting a positive engagement of the cap body with the neck of the receptacle. Heretofore, as

ing a ball valve structure have required that the receptacle with which it is used should be equipped with a particular type of neck in order to be properly and effectively associated with such type of cap.

Even though we have shown and described the preferred embodiment of the invention, it is to be understood that we do not wish to limit ourselves to the precise details of construction, combination and arrangement of elements'as herein particularly shown and described and accordingly claim all such forms of the invention to which We are entitled in view of the requirement of the prior art and the scope of the appended claim;

Having thus described our invention, what we claim as new is:

A valve cap for flexible tubes and analo gous receptacles comprising a body portion and a neck integral therewith and of a diam eter materially less than thediameter of said body portion, said body portion having a substantially semi-spherical recess provided therein in substantial alinement with said neck, and also having in the top thereof an opening concentric to said recess; a ball valve revolubly arranged in the recess and having a portion thereof projectingthrough said opening, said ball valve being also provided with a passage extending diametrically therethrough, and also having on the projecting portion thereof a manipulating pin extending at an acute angle to the longitudinal axis of said passage; and said neck also having an internal diameter substantially equal to .the largest internal diameter of said recess, and provided with internal screw threads terminating inwardly of said recess at the largest diameter of the latter.

In testimony whereof we afiix our signatures.
