COMPLETE SPECIFICATION.
Improvements in Bottles, Jars, or other similar Vessels.
I, ROBERT DANIEL BRADFORD, of 52 Gracechurch Street, London, E.C.
Merchant, 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 my invention relates to improvements in the necks of bottles, jars, or other
similar vessels, and has for its object the provision of a means for keeping firmly in
position the cork or other linings usually fixed inside the neck of the bottle, jar or
other similar vessel.
It is well known that these linings often give trouble in becoming loose and
working out of their places in the neck of the bottle, and my invention removes
these objections and ensures the cork or other lining being kept securely in its place
when fixed.
In order to carry out this invention I make the neck of the bottle, jar, or vessel
of a special shape on the inside, that is to say I provide a conical or wedge shape
ridge or projection on the inside of the upper part of the neck, said ridge being
continued all round the inside surface of the neck, and which may be of any
convenient depth.
I further provide a shoulder or projection at the lower end of the neck for the
cork to rest upon, and for a stop for said cork to prevent the possibility of it
slipping down the neck of the bottle.
It is obvious that when the cork or other lining is fitted into its place inside the
top of the neck, the elasticity of the material causes it to swell out and fit the
inside of the neck, and the point of the conical or wedge shaped ridge causes an
indent on the surface of said lining and prevents it from slipping out of its place.
Moreover when the stopper is applied to the neck that part of the lining over the
aforesaid ridge becomes somewhat reduced in diameter and fits tightly over the
stopper, thereby ensuring a tighter fit to the stopper and rendering it more effectual
in hermetically closing the bottle or jar.
In order to make my invention readily understood, reference is made to the
accompanying drawing which represents the neck of a bottle, jar, or other similar
vessel, provided with aforesaid conical, or wedge shaped ridge on its inner
surface.
A is the upper portion of the neck of a bottle, jar, or other vessel, provided with
cork or other lining B. C is the conical or wedge shaped ridge formed from the
neck of the bottle or jar. D is the shoulder or projection provided in the neck of
the bottle to prevent the cork from slipping down into the bottle or other vessel.
E is the stopper.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. The provision in the neck of a bottle, jar or other similar vessel, of a conical
or wedge shaped ridge or projection on and around the inside of said neck, said
ridge or projection being adapted to receive and hold firmly the cork or other lining
fitted to the inside of the neck for the stopper, together with a shoulder or
projection to prevent the cork or other lining from slipping downwards into the

page_text: bottle or other vessel, substantially as and for the purpose herein set forth and
described and illustrated by the accompanying drawing.
2. The application of this invention to any bottle, jar, or other similar vessel,
substantially as and for the purpose herein set forth and described and illustrated
by the accompanying drawing.
Dated this 27th day of January 1896.
