Improved Device for Covering Bottles, Jars, Bowls and other Vessels.
Year: 1896

page_text: PROVISIONAL SPECIFICATION.
Improved Device for Covering Bottles, Jars, Bowls and other
Vessels.
I, CHARLES EBENEZER CHALLIS of 47 Wray Crescent Tollington Park London N.
Machinist do hereby declare the nature of this invention to be as follows.:-
My improved device for covering bottles jars bowls and other vessels consists of a
cover of metal wood celluloid, cellulose or other suitable material having a depending
rim with a flange (hollow from the inside) at its bottom edge. In this flange is
and
inserted a rubber or other 'flexible ring and fixed by means of cement forcing the
or
flange upon it. The ring thus lies around the bottom edge of cover and projects
inwards.
When the cover is required to seal bottles jars &c. of a definite size the ring is
made narrow so as to project but slightly inside the cover and when upon the vessel it
requires considerable force to remove it unless the force be, accompanied by a twisting
movement.
The rubber also adapts itself to the configuration of a vessel screwed upon the out-
side. The covers may be made in various sizes and when the rings are of considerable
width and suitable thickness, each is capable of adapting itself to wide variations in
the size of vessels on which it is placed. The smaller sizes are suitable for domestic
vessels for the purpose of excluding dust, flies &c. while the larger sizes may be used
for invalids' chambers &c. to prevent the objectionable odours emanating therefrom.
Instead of the ring being placed inside the cap or cover it may be placed in a groove
around the outside of verge of the covers &c. which fit inside the mouth of the
vessels.

Improved Device for Covering Bottles, Jars, Bowls and other
Vessels.
I, CHARLES EBENEZER CHALLIS, of 47 Wray Crescent Tollington Park London N.
Machinist 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:-
Sering bottles om homla and other vessels consists of a

page_text: cover of metal, plain decorated or enamelled-wood, celluloid, cellulose, or other suitable
material having a depending rim with a flange (hollow from the inside) at its bottom
edge. In this flange a rubber or other flexible ring is inserted and fixed by means of
and
or
cement closing the flange upon it. The ring thus lies around the bottom edge
of cover and projects inwards. When the cover is required to seal bottles jars &c. of
a definite size the ring is made narrow so as to project but slightly inside the cover
and when upon the vessel it requires considerable force to remove it unless the force
be accompanied by a twisting movement. The rubber adapts itself to the configura-
tion of a vessel that is screwed upon the outside. The covers are made in various
sizes and when the rings are of considerable width and suitable thickness each is
capable of adapting itself to wide variations in the size of vessels on which it is
placed.
In the accompanying drawings
Fig. 1 is the cover;
Fig. 2 is the cover reversed.-A is the rubber ring and B is the flange in which it
is inserted and fixed;
Fig. 3 is a sectional view of Figs. 1 and 2.-A is the ring B is the flange--which in
practice is closed upon the rubber.-C is the cover;
Fig. 4 is a plain cover with a narrow ring.-A is the ring B is the flange and C is
the cover.
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:
An improved device for covering bottles, jars, bowls and the like constructed.
substantially as set forth, and shewn in the accompanying drawings of this
specification.
