PROVISIONAL SPECIFICATION.
An Improved Cover for Boxes for Preserves.
We, LA SOCIÉTÉ LEHUCHER & Co., of 36 Rue du Chemin Vert, Paris,
France, Manufacturers of Preserved Articles of Food, and ADRIEN MATHIEU Of
23 Rue de Sedaine, Paris, France, Chief Employe at Messrs. Lehucher & Co.,
do hereby declare the nature of this invention to be as follows:-
This invention has reference to an improved cover for hermetically closing boxes
for containing preserves, whereby consumers are enabled to inspect the contents of
such boxes without being compelled to remove the cover.
The improved cover consists of a cover-ring that is to be soldered or otherwise
fixed hermetically to the body of the box, and so stamped as to form a bed or
recess in which is arranged a disc of ordinary glass or other transparent material,
provided at its edge with a packing of rubber in which it is embedded.
The connection of the glass disc with the cover is effected by means of a ring of
stamped tinned sheet iron, that serves to receive the disc and its packing, and which
is fixed to the cover-ring by means of solder.
With this arrangement a perfectly tight joint is formed around the glass disc
and a perfectly hermetic closure of the box, effected, whilst the contents of the box
can be inspected through the sight-hole thus provided in the cover.
The ring may be provided with a projection or tongue in which there may be
inserted a ring, key or other instrument by means of which the ring can be readily
torn off when it is desired to open the box.

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 :-
This invention has reference to an improved cover for hermetically closing boxes
for containing preserves, whereby consumers are enabled to inspect the contents of

page_text: Our improved cover consists essentially of a cover-ring a soldered or otherwise
hermetically fixed to the body of a box (not shown) and so stamped as to form a
bed or recess as shown in the drawing in which is arranged a disc 6 of ordinary
glass or other transparent material, provided at its edge with a packing ring o of
rubber or other suitable material in which it is embedded.
The connection of the glass disc with the cover a is effected by means of a
ring d of tinned sheet iron having the shape shown; the said ring & serves to receive
the disc b and its packing ring c and is fixed to the cover-ring a by means of
solder e.
With this arrangement, a perfectly tight joint is formed around the glass disc b
and a perfectly hermetic closure of the box is effected, whilst the contents of the
box can be inspected through the glass b.
The ring d may be provided on its periphery (as shown in dotted lines in Fig. 2)
with a projection or tongue fin which a ring, key or other instrument g may be
inserted by means of which the ring d can be readily torn off, when it is desired to
open the box.
We do not limit ourselves to the form of cover shown in the drawing, as our
invention can also be applied equally well to covers having a circular, oval, poly-
gonal, or other shape. It is also evident that the glass plate may be of any desired
shape.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :
1. A cover for preserve boxes, consisting of a flanged sheet metal ring a
adapted to be secured to a box, a sheet metal ring d having its outer annular
edge attached to the upper surface of the flanged ring between the inner and
outer edges thereof, and a transparent disc b confined air tight at its periphery
between the inner edges of the two rings, substantially as described.
2. A cover for preserve boxes, consisting of a flanged sheet metal ring a
adapted to be secured to a box, a sheet metal ring d having its outer annular
edge soldered to the upper surface of the flanged ring between the inner and
outer edges thereof, and a transparent disc having its periphery provided with
an annular packing ring c and confined air tight between the inner edges of the
two rings, substantially as described.
