COMPLETE SPECIFICATION.
Improvements in Bottles.
We, JOHN S. MCWHORTER, Physician, and MINTER EARLE JACKSON, Book-
keeper, both residing at Janelew, in the County of Lewis, and State of West
Virginia, one of the United States of America, 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 and accompanying
drawings:
This invention relates to bottles of that class styled "Anti-Refilling Bottles,"
and it has for its objects, among others, to provide a simple and cheap construction
which will permit of the once filling of the bottle and of the emptying of the con-
tents thereof, but which will preclude the possibility of the bottle being refilled.
The construction is such that the identity of the bottle does not have to be destroyed
in order to remove its contents. A valve is interposed beneath the stopper which
is cemented within the bottle so that any attempt to introduce liquid into the
bottle will serve to force this valve to its seat, but when the bottle is turned upside
down or upon its side, the liquid within the bottle will tend to force this valve
from its seat and allow the liquid to flow through grooves or passages in the
stopper.
The invention may be applied to bottles of all shapes and sizes.
Other objects and advantages of the invention will hereinafter appear and the
novel features thereof will be particularly pointed out in the appended claims.
The invention is clearly illustrated in the accompanying drawings, which, with
the letters of reference marked thereon, form a part of this specification, and in
which,
Figure 1 is a vertical section through a bottle embodying our invention.
Figure 2 is a view showing the same tipped up and the parts in position for the
removal of the contents.
Figure 3 is a cross-section through the stopper.
Like letters of reference indicate like parts throughout the several views.
Referring now to the details of the drawings by letter, A designates the bottle
proper, which may be of any desired shape and size, the neck a thereof being
tapered, as indicated. B is an annular ledge or shoulder formed at the junction
of the neck and bottle proper.
C is a plate or valve, preferably of glass having its central portion concaved or
dish-shaped, as indicated, the annular flange thereof being joined preferably to
the bottom portion by the inclined portion of the flange c¹ and when this portion c¹
is inclined, the inner wall of this collar or flange B is correspondingly inclined, as
indicated at b. The relative diameters of this valve or stopper C and of the inner
wall of the neck at its lower end are such as to constitute a tight fit when the
stopper or valve is in its lowermost position.
D is a stopper, preferably of glass, tapered to conform to the taper of the neck
into which it is adapted to be fixedly secured by cement or analogous material,
This stopper is provided with grooves E which may be of any desired number,
extending from the lowermost edge of the stopper upward and preferably joining

page_text: at the center of the stopper at its upper end, although these grooves might be so
arranged as to terminate at different points at the end of the stopper.
The diameter of the bottom edge of the stopper 1) is larger than the diameter
of the valve C, so that when the bottle is turned on its side or bottom side up to
allow the emptying of its contents it will not close the lower ends of said grooves
or passages in the stopper D.
In practice, the bottle is filled in the usual manner and then the valve or
stopper C is placed in position with its flange resting upon the flange or collar B
at the lower end of the neck of the bottle. The stopper D is then placed in
position and cemented or otherwise permanently fixed within the neck of the
bottle and then a cork F is placed in position over or above the upper edge of
the stopper D. When it is desired to obtain access to the contents of the bottle, the
cork is removed and the bottle placed upon its side or bottom side up. When
this is done, the valve C moves away from the collar or flange B or is forced by
the pressure of the liquid against its under side and owing to the taper of the inner
wall of the neck of the bottle, a passage is formed around the edge of the stopper C,
through which the liquid passes and through the grooves or passages E of the
stopper D. Any attempt to introduce a liquid into the bottle will be frustrated
by the forcing of the valve C to its seat, thus effectually closing the passage through
the neck of the bottle.
Modifications in detail may be resorted to without departing from the spirit of
the invention or sacrificing any of its advantages.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :
1. A bottle formed with a tapered neck provided with a valve adapted to be
seated at the lower end of said neck, and a stopper permanently fixed within said
neck and having passages therethrough, substantially as and for the purpose
specified.
2. A bottle having a tapered neck and an annular interior flange at the lower
end thereof, combined with a flanged stopper adapted to be seated on the flange of
the neck, and a tapered cork permanently fixed within the neck above said valve
and having passages extending therethrough and terminating at the outer edge of
the lower end of the stopper, substantially as described.
3. A bottle having a tapered neck and an annular interior flange at the lower
end thereof, combined with a flanged stopper adapted to be seated on the flange of
the neck, and a tapered cork permanently fixed within the neck above said valve
and having passages extending therethrough and terminating at the outer edge
of the lower end of the stopper, the diameter of said valve being less than the
diameter of the lower end of the stopper, substantially as described.
