Improvements in Bottles to Prevent them being Reniled.
I, CLEMENT ALEXANDER DUNBAR, of 612, Second Avenue, in the City of Detroit,
County of Wayne, State of Michigan, U.S.A., Literary Author, do hereby declare the
nature of my invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :--
My invention relates to a non-refillable bottle and is illustrated in the annexed
drawing, wherein :-
Fig. 1, is a central vertical section of the neck of a bottle provided with my
improved device ;
Fig. 2, the same in an inverted position; and
Fig. 3, detail views.
A is a bottle. B is the neck thereof, which is formed with a contracted portion C
near its lower end, and preferably with a shouldered recess D near its mouth. E is a
tubular casing having a contracted lower extension F united to the main portion of
the casing by the annular shoulder G. Ha series of perforations in the sides of the
tube E, above the shoulder G. H¹ openings in the lower end of the tube F. I is a
packing ring of cork or similar material surrounding the tube F, below the shoulder G
and adapted, when the casing is placed in the neck of the bottle, to fit tightly into
the contracted portion C. J-is a valve comprising the head a, the contracted tubular
downward extension b, adapted to fit within the tube F, and the annular shoulder c,
on the under side of the head, adapted to seat upon the shoulder G. The head a, is
provided with a float, which may be formed either by attaching to it a piece of cork
or other light substance or by making within the head an air chamber e. f are a
series of perforations in the walls of the tube b, and d, is an imperforate portion
between the said perforations f, and the shoulder c. K is a thread or flexible
connection attached to the lower side of the head a and extending down through the
tube b. L is a weight, preferably of glass, a sphere, which is attached to the lower
end of the connection K. M is a partition or baffle plate extending across the
casing E. This I preferably form as the bottom of a cup shaped casing N fitting
into the upper end of the casing E against a bead g and forming an upward extension
of said casing. Near its upper end the casing N is provided with a series of
perforations h. In practice after the bottle is filled, the casing containing the valve is
placed in the neck of the bottle, the packing ring I fitting into the contracted
portion C. The casing is then secured by expanding the upper end of the casing N
so as to fit against the shoulder at the top of the annular recess D. To pour out the
liquid from the bottle, it is only necessary to incline it to a sufficient angle for the
weight L to run down the tapering shoulder O, of the bottle, which will relieve
the tension of the connection K, and allow the valve J, to open outwardly. The end
of the tube F, forms a seat which will catch the weight and prevent it from falling
into the neck of the bottle, and the liquid will pass through the aperture H into the
said tube and into the tube b, passing through the perforations f and H, into the
annular space R, surrounding the casing E, and thence through the perforations h,
out of the mouth of the bottle.

page_text: That the bottle when once emptied cannot be refilled will be readily understood,
as it will be seen that the only way in which the valve J can be opened, is to invert
or downwardly incline the bottle, and if in this position it were immersed, the liquid
would carry the float valve to its seat.
Having now particularly described and ascertained the nature of my said inven-1
tion and in what manner the same is to be performed, I declare that what I
claim, is :-
1. In a non-refillable bottle, the combination with a bottle neck, of a valve
mechanism for permitting the outflow and prohibiting the inlet of liquid, and
comprising a ported casing, a buoyant valve for governing the ports of the casing,
and provisions whereby the valve may have an extended reciprocating movement while
acting to close the ports, and a counteracting weight.
2. In, a non-refillable bottle, a buoyant elongated piston valve, an elongated seat
over which the valve has to move to be opened, and a counteracting weight suspended
by a flexible cord within the bottle.
3. In a non-refillable bottle, the combination with a cylindrical casing within the
neck of the bottle provided with an annular valve seat at its inner end, of a buoyant
piston valve slidingly secured in said cylindrical casing and having outlet ports
adapted to be disclosed by the outward movement of said piston, a head on said piston
adapted to seat on said annular seat and a weight within the bottle suspended from
said valve for holding it in its closed position.
4. In a non-refillable bottle, the combination with a cylindrical casing within the
neck of the bottle, of a piston valve slidingly secured in said cylindrical casing,
having outlet ports adapted to be disclosed by the outward movement of the valve, a
float secured to said valve and a weight within the bottle suspended from said valve
for the purpose described.
