PROVISIONAL SPECIFICATION.
Improvements in and relating to Covers or Stoppers for Preserve Jars
or Bottles.
I, ALLAN CARSWELL, of 7, Spring Bank Road, Paisley, in the County of
Renfrew, Preserve Maker (operative), do hereby declare the nature of this inven-
tion to be as follows:-
This invention has for its object to provide a practically air-tight cover or
stopper for preserve jars or bottles which may be self-fastening when pressed
into position over the jar or bottle mouth.
The cover which may be made of tin plate or other suitable material is
dished or made with a turned down edge which is slit or cut out vertically at
intervals so as to form three or more peaks or flexible prongs round its edge.
Each of the said peaks or prongs has cut and pressed or otherwise formed on
its inner face a projecting catch adapted to engage with the lower side of a
lip or flange formed on the mouth of the jar or bottle or to spring into a groove
therein.
A ing or band of cork, rubber or other flexible material is fitted within the
cover to form a tight joint at the mouth of the jar when the cover is pressed
down and is held thereon by the catches springing into the groove or under the
lip or flange, and a metal band may be fitted over the cover to retain the peaks
or prongs close to the mouth of the jar with the catches in engagement with
the lip, flange or groove.
The packing ring of rubber or other material may be cut from rubber or
other tubing to form a thin ring bearing between the cover and the upper side
of the jar mouth, or it may be made to fit around the outside of the jar mouth
and bear against the flange of the cover. In the former case a dished up sheet
metal disc may be interposed between the packing ring and the cover and the
latter may be formed with a central depression which when pressed down on
the disc fends to flatten it and causes it to press against the packing ring and
thus tightly close the jar mouth even should the fastenings of the cover allow
of some play when engaging the jar neck.

Improvements in and relating to Covers or Stoppers for Preserve Jars
or Bottles.
I, ALLAN CARSWELL, of 7, Spring Bank Road, Paisley, in the County of
Renfrew, Preserve Maker (operative), do hereby declare the nature of this inven-
TD 077

page_text: tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:—
This invention has for its object to provide a practically air-tight cover or
stopper for preserve jars or bottles which may be self-fastening when pressed
into position over the jar or bottle mouth.
The invention is illustrated by the accompanying drawings, Figure 1 being
an elevation of a preserve bottle shewing the improved cover applied thereto,
Figure 2 an elevation partly in section shewing the method by which the cover
is retained upon the preserve bottle, and Figure 3 is a plan of said bottle.
The cover A which may be made of tin plate or other suitable material is
dished or made with a turned down edge which is slit or cut out vertically at
intervals so as to form three or more peaks or flexible prongs Around its
edge. Each of the said peaks or prongs A' has cut and pressed or otherwise
formed on its inner face a projecting catch A2 adapted to engage with the
lower side of a lip or flange B formed on the mouth of the bottle or jar B, or
to spring into a groove therein.
A ring or band C of cork or rubber or other flexible material is fitted within
the cover A to form a tight joint at the mouth of the jar B when the cover A
is pressed down and is held thereon by the catches A2 springing into the groove
or under the lip or flange B', and a metal band may be fitted over the cover A to
retain the peaks or prongs close to the mouth of the jar B with the catches A²
in engagement with the lip, flange or groove.
The packing ring C of rubber or other material may be cut from rubber or
other tubing to form a thin ring bearing between the cover A and the upper
side B of the jar mouth, or it may be made to fit around the outside of the
jar mouth and bear against the flange of the cover A. In the former case
a dished up sheet metal disc D may be interposed between the packing ring C
and the cover A and the latter may be formed with a central depression A³,
which when pressed down on the disc D tends to flatten it and causes it to
press against the packing ring C and thus tightly close the jar mouth even
should the fastening of the cover allow of some play when engaging the jar
neck.
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 self fastening stopper or cover for preserve jars or bottles consisting of
a dished plate having a number of peaks, each of which has a catch formed on
its inner side and adapted to engage with a lip, flange or groove on the jar neck
and form an air-tight joint, substantially as described.
