This invention relates to improvements in stoppers for bottles, jars, tin cans and
the like, and has for its object the provision of stoppers which can easily be fitted
to the top of the neck of bottles, jars, and similar receptacles, and also easily removed
when so required.

of
open at its upper edge, which upper edge is formed with a series
lugs capable of being turned down for the purpose hereinafter described. At a
sufficient distance from its upper edge the said cap is turned inwards around its
circumference so as to form a flange and on two opposite sides the lower portion of the
cap is cut away to form two tongues, and the lower end of each tongue is further
formed with a lug in the shape of a hook. The object of these hooks is to provide
a locking device to secure the stopper to the bottle. This I accomplish by forming on
the neck of the bottle or other receptacle two tapering projections one opposite to
the other and so shaped that the hooks on the aforesaid tongues of the cap shall, on
being slightly turned when' the cap is fitted on the neck, pass under said tapering
projections and be held in place by them.

I place a disc of cork in the upper part of the cap so that the cork shall be held
in the flange herein before described and, when in use, fit tightly on the top of the
neck of the bottle, and to the upper part of said cork, I attach a metal disc of
the same size as the cork. I further provide an upper disc of metal, and between the
two discs and to either of them I secure a flat steel spring. In order to fit this my
improved stopper together, the cork and two metal discs, having the spring between,
are dropped into the upper part of the cap aforesaid and rest upon the flange. The
upper lugs are then bent over and down on the upper metal disc, and thus the cork
discs and spring are in position. To fit the stopper on the bottle the cap is placed
over the neck of the bottle and pressed down on the top and slightly turned until

pressure is released the spring exerts an upward pressure and the stopper is locked.
If desired I'may prolong a portion of the sides of the stopper and turn up the
lower edges of the same, and attach a chain thereto, said chain being secured to the
bottle or jar by lugs or other suitable means; and the stopper inay be used either
with the chain or without..

page_text: I, JOHN TREVOR WILLIAMS, of 19 and 21, Queen Victoria Street, in the City of
London, Gentleman, 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 improvements in stoppering bottles, jars, tin cans and
the like and the object of my invention is to enable bottles jars and like receptacles
to be readily stoppered or unstoppered.
In order that my invention may be readily understood reference is made to the
accompanying drawing wherein Fig. 1 is a sectional side elevation of my improved
stopper; Fig. 2 is a side elevation of a part of a bottle having its top or mouth
formed in accordance with my invention; and Fig. 3 is a plan view of Fig. 2.
In carrying my invention into practice I employ a tubular cap or cover A which
is preferably though not necessarily of larger diameter at its upper end. Its lower
end is cut away about as shown so as to leave preferably two extensions a a, situated
opposite to each other and which at their bottom ends are bent inwards so as to form
hooks or equivalents as shown at a¹. The top or mouth B of the bottle is, in
accordance with my invention formed with two gradually increasing lugs or exten-
sions b which also are situated opposite each other, the arrangement being such
that if the cap A be put on by passing the hooks a¹ to a sufficient extent down the
narrow part of the top of the bottle and the cap be then turned, the hooks a¹ of the
cap will be brought under the lugs or equivalents 6 and said cap cannot be pulled
off until it has been turned back again to its original position, so that the hooks a'
may pass up the narrow part of the mouth or top of the bottle.
For the purpose of closing or stoppering the mouth of the bottle I insert a disc of
cork or other suitable material C into the top of the cap, said cork resting on the
shoulder formed by the difference in diameter of the upper and lower parts of the
cap and in order to protect and strengthen said disc of cork I place thereon a metal
disc D. The top of the cap A I provide with a metal disc E which is held in place
by lugs or the like e and between the discs D and E I provide a spring F preferably
fastened to the disc D which spring normally presses the metal disc D and conse-
quently the cork disc C down to their lowermost position the arrangement of the
whole being such that when the cap is put on as before described the cork disc will
press against and close the mouth of the bottle.
I wish it to be understood that I do not confine myself to any particular shape
or dimensions of the different parts constituting my invention nor to any material
of which said parts may be made and in referring herein to a bottle-which I show
merely for the purpose of illustrating my invention-I wish it to be understood
that such invention may with equal advantages be applied to jars, tin cans, and the
like. Further, if desired the cap A may be attached to the bottle by means of a
chain or otherwise in any suitable manner to prevent its being lost.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:-
1. The combination with a bottle, jar, tin can or the like having lugs or equiva-
lents such as b, of a stopper consisting of a cap A having hooks a¹ a cork-or equiva.
