1 WILLIAM BOWERS FITCH, of New Cross Glass Works, Deptford, in the county
of Kent, Chemist do hereby declare the nature of this invention to be as follows :-
This invention relates to forming the outside of the neck of the bottle to be
stoppered or closed with a screw thread preferably undercut and adapted to receive
5 and retain a stopper, cover or cap provided with a number of spring like projections
carrying catches or clips in such a manner that to close the bottle it is simply
necessary to press the stopper, cover or cap over the top of the bottle the said catches
taking into and being retained in position by the screw thread. To open the bottle it
is simply necessary to unscrew the stopper, cover or cap.
10: The joint between the bottle and the stopper is made by means of a washer or disc
of any suitable elastic material.

Improvements in Closing or Stoppering Bottles.
I WILLIAM BOWERS FITCH, of New Cross Glass Works, Deptford, in the county of
Kent, Chemist, 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 forming the outside of the neck of the bottle to be
stoppered or closed with an undercut screw-thread adapted to receive and retain a
stopper, cover or cap provided with a number of spring like projections carrying

page_text: catches or clips in such a manner that to close the bottle it is simply necessary to
press the stopper, cover or cap over the top of the bottle, the said catches taking into
and being retained in position by the screw-thread. To open the bottle it is simply
necessary to unscrew the stopper, cover or cap.
The joint between the bottle and the stopper is made by means of a washer or disc
of any suitable elastic material.
In the accompanying drawing figure 1 represents a sectional elevation of part of
a bottle closed or stoppered according to my improvements; figure 2 is an elevation,
and figure 3 a plan of the stopper, cover or cap, and figure 4 is an elevation of part
of the bottle adapted to receive the said stopper, cover or cap. Similar letters in all
the figures represent similar parts.
a (figures and 4) represents the undercut screw-thread which I form on the
outside of the neck 6 of the bottle, which is thereby adapted to receive and retain my
stopper, cover or cap c, illustrated in figures 1, 2 and 3; d, d, d, d are the spring
like projections with which I provide the cap c, the said projections being advantageously
formed by cutting the sides of the cap in the manner illustrated more clearly in
figure 2 of the drawing; e, e, e, e are the clips or ratchets on the projections d, d, d, d,
which clips or catches are conveniently formed by turning up the bottom edges of the
said projections; fis the usual washer or disc of elastic material for forming the joint
between the stopper c and the mouth of the bottle.
In order to close a bottle provided with a screw-thread on the neck as described,
by means of my stopper, cover or cap c it is only necessary to press the stopper
over the mouth of the bottle when the spring clips or catches e thereof will pass
over the screw-thread a on the bottle neck 6 until the washer or disc f comes
against the mouth of the bottle the catches taking into the screw-thread; by then
giving a partial turn to the stopper c the clips or catches e will be caused to turn
in the screw-thread and the washer or disc will be thereby pressed closely over the
mouth of the bottle.
To open the bottle it is simply necessary to unscrew the stopper, cover or cap c as
will be well understood, the head of the latter being milled or serrated to facilitate its
being turned.
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 having an undercut screw thread on its neck of a
cap, cover or stopper having spring catches or clips adapted to take into the undercut
screw thread substantially in the manner and for the purpose hereinbefore
described.
2. The manufacture and use of the improved bottle and stopper hereinbefore
described and illustrated in the accompanying drawing.
