Improvements in Stoppering Bottles, Jars, and other Receptacles.
I, JOHN JAMES PILLEY, of 167, Camberwell Grove, London, S.E., Professor of
Chemistry, do hereby declare the nature of this invention to be as follows:-
According to my invention I construct a capsule for the hermetic closing of bottles,
jars and other receptacles of any suitable substance or material capable of being
moulded or pressed to the required shape, as follows:-
The capsule is recessed in the centre so that the top of the receptacle fits into the
annular space thus formed between the outer rim of the capsule and the rim of the
recessed portion. Upon the inner and outer rims of the capsule I form a screw thread
or helical projecting ridge to engage with a corresponding thread or ridge which I
form both inside and outside the neck of the bottle or other receptacle. An annular
cushion or washer of cork, cardboard, rubber, paraffin wax, or any other suitable seal-
ing material is placed over the top of the neck of the receptacle so that on the capsule
being screwed down a perfectly hermetic closure is effected.
I, JOHN JAMES PILLEY of 167, Camberwell Grove, London, S.E., Professor of
Chemistry, do hereby declare the nature of this invention and the manner in which
the same is to be performed to be particularly described and ascertained in and by the
following statement :-
According to my invention I construct a capsule for the hermetic closing of bottles,
jars and other receptacles of any suitable substance, or material capable of being
moulded or pressed to the required shape as follows:-
The capsule is recessed in the centre so that the top of the receptacle fits into the
annular space thus formed between the outer rim of the capsule and the rim of the
recessed portion. Upon the inner and outer rims of the capsule I form a screw thread
or helical projecting ridge to engage with a corresponding thread or ridge which I
form both inside and outside the neck of the bottle or other receptacle. An annular
cushion or washer of cork cardboard, rubber, paraffin wax or any other suitable
sealing material is placed over the top of the neck of the receptacle so that on the capsule
being screwed down a perfectly hermetic closure is effected.

page_text: I will now describe my invention with reference to the accompanying drawing
Figure 1 of which is an elevation and Figure 2 a sectional elevation shewing the capsule
fitted to a bottle.
A Figure 2 shews the recessed or sunken portion of the capsule upon which the
designs names or any device may be placed. B.is the raised portion forming the
groove or annular space into which the neck of the bottle or other receptacle fits as
shewn in Figure 2. C Figures 1 and 2 is the outer rim and D Figure 2 is the inner
rim of the capsule upon which are formed the screw threads corresponding with the
threads formed upon the neck of the bottle or other receptacle, and which threads on
the outer rim are suitably milled for screwing and unscrewing the capsules. E Figure 2
is the cushion or washer of any suitable material for forming the airtight joint
when the capsule is screwed tightly down over the mouth of the bottle, jar or other
receptacle as previously described.
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 :-
A capsule of any suitable material so formed with a recessed portion that the sides
of the recess and the outer rim of the capsule form a groove or annular space having
upon these inner and outer sides screw threads corresponding with the screw threads
formed on the neck of the bottle jar or other receptacle which screws into this
annular space or groove, the-bottle jar or other receptacle being rendered airtight
by means of an annular ring of cork, cardboard rubber paraffin wax or other material
which is placed over the top of the neck of the receptacle the whole as before
described and illustrated in the accompanying Drawing.
