Improvements in Bottle Stoppers.
HARRY MAINWARING DUNSTAN, College Hill Chambers, Cannon Street,
London, E.C., Financial Agent, do hereby declare the nature of this invention, and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to the manufacture of a bottle stopper which can be opened
so as to allow of the contents of the bottle being withdrawn at will, either wholly
or partially, and closed without withdrawing the stopper from the bottle. It is
applicable principally to sauce and all bottles in which the contents are to be
shaken out, and can be made of material which is proof against chemical action.
According to this invention I construct a stopper of cork or other suitable material
with a perforation through the centre of sufficient size to admit a tube of wood or
other suitable material, closed at the lower end, and having a perforated head or
cap of the same.
In the lower end of the stopper I cut cross notches at opposite sides up to about
half its depth, and through the tube a hole is pierced corresponding in position to
the said notches, so that when the stopper is inserted in the bottle, and the tube is
inserted in the perforation of the stopper, the said tube may be turned horizontally
after the manner of a stop-cock so as to bring the orifice opposite the notches in
the stopper, thus opening a free passage into the interior of the bottle. By turning
the tube into any other position the communication is closed.
In order to indicate the open and closed positions I fix on the upper rim of the
stopper an index pointer of metal overlapping the edge of the cap, upon which
latter two points are marked with the words "open" and "shut" respectively.
In order to render the above description more generally intelligible I attach
drawings, forming part of the Complete Specification,
which,
Fig. 1. A. represents the perforated cork stopper with side slot.
Fig. 1. a. represents the metal index attached to it.
Fig. 1. b. represents the slot
Fig. 2. B. represents the cap and tubular plug fitting into the above.
Fig. 2. c. represents the side orifice in tube, above the closed end.
Fig. 3. C. represents the complete stopper when open.
Fig. 3. d. represents the side orifice opposite slot, admitting the liquid.
Fig. 4. D. represents the complete stopper when closed.
Fig. 4. e. represents the side slot closed by turning the cap and plug.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The application to the manufacture of bottle-stoppers of the stop-cock action,
serving the purpose of stopper, cork or tap, substantially as above specified.
2. The use for the same object of the pointer on the stopper, and the index
marks on the cap, showing the open and closed positions of the stopper as above
specified.
