Improvements in Means for Closing and Sealing Cans and Canisters
Containing Varnish, Paint, Oil or other Liquid Substances.
I, JAMES GARNETT HEYWOOD, of 127 Sutherland Avenue, Maida Vale, in the
County of Middlesex, Gentleman, do hereby declare the nature of this invention to
be as follows:-
This invention relates to cans and canisters for containing varnish, paint, oil
or other liquid substances, and has for its object an improved device for closing
or sealing such cans and canisters.
According to my said invention I provide the can or canister with a taper neck
to be closed by a corresponding taper cap or cover which fits closely over the neck.
This cap is secured in position by a metal band soldered around the neck and
around the lower edge of the cap. I provide the said band with a suitable pro-
jecting end or lug to enable it to be caught hold of for the purpose of stripping it
off when it is desired to open the can. The cap is preferably provided with a pro-
jecting rim at its upper end or with a milled-head, or with lugs or the like to
facilitate the removal of the cap by enabling a better grip to be obtained thereon
by the hand. The aforesaid cap can be very readily removed from the neck after
the soldered band has been torn off and can be instantly re-applied and will make
an air-tight joint with the neck thus ensuring the perfect preservation of the
contents of the can.
In some instances I provide an opening in the top of the cap which opening is
closed by a disc or cover plate soldered to the cap after the can has been filled.

Improvements in Means for Closing or Sealing Cans and Canisters
Containing Varnish, Paint, Oil or other Liquid Substances.
I, JAMES GARNETT HEYWOOD, of 127 Sutherland Avenue, Maida Vale, in the
County of Middlesex, Gentleman, do hereby declare the nature if 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 invention relates to cans and canisters for containing varnish, paint, oil or
other liquid substances, and has for its object an improved device for closing or
sealing the same.

page_text: For the purposes of my invention I provide the can or canister with a taper neck
which is surmounted by a closely fitting taper cap or cover secured in position by
a metal band soldered around it...
The said band can be stripped or peeled off very readily when required and then
the cap can be removed and replaced as often as desired, and when replaced it
makes an air-tight joint with the neck-and-ensures the perfect preservation of the
contents of the can or canister.
In order that my invention may be more readily understood I will now describe
the same with reference to the accompanying drawings, in which.
Fig. 1 is a perspective view of a portion of a can furnished with my improved
closing device.
Fig. 2 is a central section of the neck and cap or cover.
Fig. 3 is a section of the neck alone.
Fig. 4 is a section of the cap or cover, and
Fig. 5 is a section of the disc for closing the top of the cap after the can has been
filled.
Fig. 6 is a section of a closing device furnished with a lug for facilitating the
removal of the cap.
Fig. 7 illustrates a modification hereinafter described.
Like letters of referenca denote corresponding parts in the several figures.
A is the can, B is the taper neck of the can, C is the cap for closing the neck,
D is the disc for closing the opening in the top of the cap, and E is, the metal band
for securing the cap to the neck.
I prefer to construct the neck B with a shoulder at b, so that when the cap is
placed on the neck its outer surface is flush with the outer surface of the lower part.
of the neck. The band E is placed around the neck and the lower edge of the cap
as indicated in Figs. 1 and 2, and is soldered thereon, so as to firmly hold the cap
in position and to make a perfectly air-tight seal. An opening e is provided in the
crown of the cap C to admit of filling the can, and after the can is filled, this open-
ing is closed by a disc D placed on the top of the cap, and retained in position by
solder. This disc is not intended to be again removed. The crown of the cap is
conveniently made with an annular chanel e as indicated in Fig. 4 to receive the
rim of the disc D, but this construction can be modified in various ways. The
positions of the various parts when placed together are indicated by Figs. 1 and 2.
To open the can, the soldered band E, is stripped or peeled off, for which purpose
the end e of the band, see Fig. 1, may be conveniently left projecting to enable it
to be seized by the thumb and finger, or any other convenient method may be
adopted to allow of stripping off the metal hand, for instance the end of strip may
have a hole in it to allow of a string being passed through by which the band can
be peeled off. The cap C can then be removed, and as much as desired of the con-
tents of the can may he poured out, and the cap then replaced on the neck. I
preferably construct the cap with a projecting rim at its upper end or with a
milled edge to facilitate the removal of the cap by enabling a firm grip to be
obtained thereon by the hand; or a lng such as e Fig. 6 can be provided to allow
of easily removing the cap.
If the cap should stick it can be jerked off by a piece of string passed through
the eye of the lug. Owing to the taper formation of the cap and neck, a perfectly
satisfactory air-tight joint is made by them, and the contents of the can are thus
preserved from deterioration while access to the contents is rendered easy, and
the maximum of clealiness is attained. If desired the cap and disc can be made in
one piecè."
Much time is saved in opening and re-closing a can or canister furnished with
the described closing device as compared with methods that have been heretofore
commonly employed, as for example those wherein bungs covered with wash
leather and sealed with plaster of l'aris are used. Another important advantage
arising from my invention as applied to varnish cans is that any skin formed at
the mouth of the can after some of the varnish has been poured out is not forced

page_text: into the can as heretofore, and moreover there are no pieces of cork or plaster of
Paris or the like to fall into the can and deleteriously affect the contents thereof
as in some methods.
I sometimes reverse the construction by arranging the conical neck with the
larger end upwards instead of downwards in which case the cap or cover fits inside
the neck as shown in Fig. 7 instead of outside. I prefer however to employ the
construction first described.
It is obvious that my invention can be applied to the sealing of metallic packages
generally.
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:-
The closing or sealing of cans or canisters or metallic packages by means of a
taper neck and taper cap with peel off strip, substantially as, and for the purposes
hereinabove described.
