The object of this invention is to provide an airtight lid or cover for bottles jars
cans &c. by means of a double-flanged lid & is constructed as follows-
The lid has two flanges-being of the shape of an inverted letter U-one flange
fits on the outside of the bottle &c.-the other running on the inside of same-
both these flanges have a screw thread which corresponds with a similar thread on
the top end of the bottle &c. &c.
In the apex of the two flanges I insert a ring or washer of rubber or other
suitable material-so that when the lid is screwed down the washer engages the
top of the bottle &c. the same being thereby rendered perfectly airtight.

Improvements in Lids or Covers for Bottles, Jars, Cans, and
the like.
JOHN BANBURY Engineers Broker Burford Oxfordshire England 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 :-
The object of this invention is to provide cans jars bottles and the like (which
have screw threads impressed more or less distinctly on both the interior, and
exterior of the tops or necks thereof) with a new shape of lid or cover.
The said lid or cover has two rims or flanges being shaped like an inverted
letter U, the said flanges may be placed at varying distances or widths apart-to
suit the thickness of the necks or tops of vessels to which they have to be applied
so that when the can jar or vessel is made perfectly cylindrical, the flanges will
engage or rest against the outside and inside thereof. The vessels to which these
lids have to be applied will need to be made true, or they cannot be expected to
engage or come into contact with the entire circumference thereof.
These said flauges have screw threads impressed therein of corresponding guage
or thread to those on the vessel to which the lid is to be applied-so that when the
lid is placed over the end of the said vessel the threads on the flanges thereof will
readily engage or marry into those on the outside and inside of the vessel, thereby
-when turned, drawing the lid firmly down on the top thereof.
In the apex of the flanges one or more rings or washers of rubber or other
suitable material are inserted, so that when the lid is firmly screwed down, the
washers are securely pressed on the top of the vessel, thereby providing a perfectly
airtight closure.
Having in the above description, explained the nature of my invention, I do not

page_text: restrict myself exclusively to the descriptions therein given, as many modifications
may be introduced without departing from the principles thereof.
Reference is to be had to the accompanying drawings forming part of this
Specification, in which similar letters of reference, refer to corresponding parts in
the views.
Fig. 1. is a vertical section through a double flanged lid with countersunk top
made on my principle.
Fig. 2. is also a vertical section of a lid having a plain flush top with double
flanges, on my principle.
Fig. 3. is a sectional view of the same shaped lid as Fig. 1. but showing the screw
threads impressed therein and the washer inserted.
Fig. 4. is a section of the same shaped lid as Fig. 2 also showing screw threads
impressed, and washer inserted.
Fig. 5. is a sectional view of double flanged lid with a plain top showing its
adaptation to an ordinary tin can or other sheet metal vessel having the screw
threads on outside and inside the top thereof.
Fig. 6. also shows a sectional view of a double-flanged lid with recessed top
showing its adaptation to glass-bottles, jars, & other holloware.
In each case the lid A is shown as made of sheet metal or other suitable
material.
The screw thread impressions are shown in Figs. 3, 4, 5, and 6 by the letter B.
The washers or seating is shown in Figs. 3, 4, 5, and 6 by the distinguishing
letter C.
The body of the tin or can in Fig. 5. is shown by letter D and the neck or top
by letter E.
In Fig 6. the body of the bottle or jar is shown by the letter F and the neck or
top by letter G.
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-
The system or method of making an airtight lid or cover, for cans bottles jars
and the like by providing the lid with two screwed flanges for the purpose of
engaging both the outside and the inside threads of the neck of the vessel-
together with a suitable flexible washer or seating-substantially as set forth and
described in the accompanying Specification and drawings.
Dated this 28th day of May 1895.
