I, JOSEPII ANTOINE VALENTIN BOURGEOIS, the elder, of 71, Boulevard Voltaire,
Paris, France, Inventor, do hereby declare the nature of this invention to be as
follows:
-
The object of this invention is to provide for the hermetic closure of vessels
for containing oil paint ready prepared for use, and thus to avoid desiccation of
the contents of the vessel, and it is more especially applicable to containers
made of tin or other thin metal of which the parts constituting the lid and its
adjuncts would also be made.
According to my invention the body of the vessel (which may be of the
ordinary cylindrical form having a bottom soldered thereto as usual) is provided
with an annular flange or bead which extends around the mouth of the vessel
and is soldered to the outer surface thereof, the said flange being of inverted
U-form and presenting an upwardly projecting rim whose upper surface is convex
whilst the outer rim of the inverted U has a slight outward inclination. The
cover is provided with a correspondingly shaped rim or margin adapted to fit
upon the flange of the vessel and (by reason of the certain amount of elasticity
which the two portions possess) to ensure a practically hermetic joint. To make
the closure more secure, the lower edge of the flange of the vessel, and the lower
edge of the rim on the cover, are each provided with an outwardly directed
marginal flange capable of affording resistance to any strain which might tend
to damage the closing device; these flanges serving the further purpose of
affording facility for opening the vessel which can be effected by passing a knife
blade between the marginal flanges of the vessel and cover so as to separate
same and, by overcoming the tendency of the flanges to adhere, raise the cover
from the vessel. The cover is positively secured in position by means of two
or more clips or latches which are hinged to the body of the vessel and when in
the locked position extend over the top surface of the rim of the cover on which
their free extremities bear with a wedging action so as to lock the cover in place
and afford resistance to any internal pressure which, when the vessel is full and
subjected to accidental compression, may tend to raise the cover from the vessel.
In lieu of the jointed latches I may employ loose clips in the form of hooks
adapted to engage beneath the flange on the vessel and to embrace the rim
and flange and to bear upon the cover in the same way as do the hinged clips:
each of these loose clips being provided with a curved tail piece serving as a
lever by which to force the clip down upon the cover the end of the lever having
its extremity bent up so as to enable it to be raised by the finger. Each clip
has also a lateral extension which when passed beneath the flanges serves to
enable the cover to be detached. The loose clip thus serves as a key by means
of which the cover may be both closed and opened.
The marginal flanges also serve for the attachment of a safety seal, for which
purpose the flanges would have holes for the passage of a cord or wire of which

page_text: the extremities would be united by a lead seal so as to guard against tampering
with the contents.
The invention may be applied to existing vessels (after the removal of the
cover) by merely soldering the annular flange to the body of the vessel. The
vessel provided as above with the flexible flange may be used as an ordinary
paint pot and may be cleaned out with the same case as ordinary paint pots or
containers when the paint has become dried therein.

I, JOSEPH ANTOINE VALENTIN BOURGEOIS, the elder, of 71, Boulevard Voltaire,
Paris, France, Inventor, 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 for the hermetic closure of vessels
for containing oil paint ready prepared for use, and thus to avoid desiccation of
the contents of the vessel, and it is more especially applicable to containers
made of tin plate or other thin metal, of which the parts constituting the lid
and its adjuncts would also be made.
In the accompanying drawings Figures 1 and 2 show respectively a vertical
section and elevation of a paint pot provided with the means for effecting an
hermetic closure. Figures 3 and are corresponding plan views of the same.
According to my invention the body A of the vessel (which may be of the
ordinary cylindrical form having a bottom soldered thereto as usual) is provided
with an annular flange or bead B which extends around the mouth of the vessel
and is soldered to the inner or outer surface thereof, the said flange being of
inverted U-form and presenting an upwardly projecting rim whose upper surface
is convex whilst the outer member of the inverted U has a slight outward
inclination. The cover C is provided with a correspondingly shaped rim or
margin c produced by stamping or otherwise which is adapted to fit upon the
outside of the flange of the vessel and (by reason of the certain amount of
elasticity which the two portions possess) to ensure a practically hermetic joint.
To make the closure more secure, the lower edge of the flange of the vessel, and
the lower edge of the rim on the cover, are each provided with an outwardly
directed marginal flange b¹, c¹ respectively, which flanges are capable of affording
resistance to any strain which might tend to damage the closing device and
also serve the further purpose of affording facility for opening the vessel which
can be effected by passing a knife blade between the marginal flanges of the
vessel and cover so as to separate the same and, by overcoming the tendency of
the flanges to adhere, raise the cover from the vessel. The cover is positively
secured in position by means of two or more clips or latches a (Figures 2 and 4)
which are hinged to the body A of the vessel and when in the locked position
extend over the top surface of the rim of the cover on which their free extremities
bear with a wedging action so as to lock the cover in place and afford resistance
to any internal pressure which, when the vessel is full and subjected to accidental
compression, may tend to raise the cover from the vessel.
In lieu of the jointed latches I may employ loose clips a (Figures 1 and 3) in
the form of hooks adapted to engage beneath the flange b¹ on the vessel A and

page_text: to embrace the rim c' and to bear upon the cover C in the same way as the hinged
clips; each of these loose clips being provided with a curved tail piece a serving
as a lever by which to force the clip down upon the cover, the end of the lever
having its extremity bent up so as to enable it to be conveniently raised by the
finger. Each clip further has a lateral extension a² which, when passed beneath
the flanges c¹ serves to enable the cover to be detached. The loose clip thus
serves as a key by means of which the cover may be both closed and opened.
The marginal flanges b', c¹ may serve for the attachment of a safety seal
(Figure 3) for which purpose the flanges would have holes for the passage of a
cord or wire f of which the extremities would be united by a lead seal p so as to
guard against tampering with the contents of the tin.
The invention may, after the cover has been removed, be applied to an existing
A further
vessel by merely soldering the annular flange to the body of the vessel.
advantage gained is that the paint cannot penetrate between the annular flanges
and so clog it.
A vessel provided as above with the flexible flange may be used as an ordinary
paint pot and may be cleaned out with the same ease as ordinary paint pots or
containers when the residue of the paint has become dried thereon.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. The herein described means for hermetically closing oil paint containers,
consisting of a cover provided with a rim of the form shewn adapted to fit with
a certain amount of elasticity upon an annular flange or bead of inverted U-form
fixed to the mouth of the vessel, as specified.
2. The combination with the container provided with a cover and both con-
structed as described of the hinged or independent clips or latches adapted to
serve both for securing the cover in place and for detaching it from the vessel,
as specified.
