We FRANK HAZEN PALMER of 123 Fourth Street Long Island City, Queens County
State of New York, Paint and Varnish Manufacturer and WILLIAM HENRY BOWLSBY
of Van Siclen Avenue Brooklyn in the State of New Jersey United State of America
Doctor of Medicine do hereby declare the nature of this invention to he as
follows:-
The object of this invention is to provide a cover for fruit and other jars, cans,
paint and other boxes and like receptacles, which is very simple in construction, easily
fastened on the jar or box, and which will make an air-tight closure and prevent
leakage of the contents.
The Invention consists of a cover provided on top with one or more spring cross-
bars having downwardly and inwardly extending arms adapted to be sprung over and
engage with bevelled lugs or a rim on the side of the jar or box.
The Invention also consists of a specially prepared disc clamped upon the edge of the
mouth of the jar, box, or receptacle, by the pressure of the cover applied through a
packing ring situated between the disc and cover.
The spring cross-bar or bars is or are fixed by soldering or otherwise, on a central
projection on the cover, and if two such bars are used they are placed at right angles.
They extend beyond the edge of the cover and are bent downwards to form arms,
each of which is provided with an inwardly projecting short lug adapted to be sprung
(by downward pressure on the outer end of the bar) down over the bevelled lug on
the side of the receptacle and to engage with the underside thereof, so as to hold the
cover tightly on the mouth of the receptacle. The cover is flanged and a packing ring
is placed between it and the disc closing the mouth of the jar, said disc being
preferably made of paper coated or saturated with a suitable substance which is not
affected by the contents of the receptacle. For instance, for certain goods containing
a good deal of water, paraffin paper is employed, and for other goods such as paint, a

page_text: paper disc thinly coated with glue is used. The packing ring is preferably made out
of blotting paper, but felt, rubber, or similar material may be used. It is placed in
the cover before the latter is adjusted on the mouth of the receptacle, and the thin disc
is placed on the upper edge of the receptacle to which it about corresponds in diameter.
The cover is then placed over the receptacle and pressed downwards, after which, by
pressure on the outer ends of the spring bar or bars, the arms are moved downwards
and their inwardly projecting lugs snap under the bottom edge of the lugs on the side
of the receptacle.

Improved Means of Closing Jars and other Wide Mouthed Vessels.
I, FRANK HAZEN PALMER of 123 Fourth Street, Long Island City, Queens County,
State of New York, United States of America, Paint and Varnish Manufacturer and
WILLIAM HENRY BOWLSBY, of Van Siclen Avenue, Brooklyn, State of New Jersey,
United States of America, Doctor of Medicine 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 a cover for fruit and other jars, cans, paint
and other boxes and like receptacles which is very simple in construction, easily
fastened on the jar or box and which will make an air tight closure and prevent leakage
or spilling of the contents.
The invention consists of a cover provided on top with one or more spring cross
bars having downwardly and inwardly extending extremities or arms adapted to be
sprung over and engaged with bevelled lugs or a rim on the side of the jar or box.
The invention also consists of a specially prepared disc clamped upon the edge of
the mouth of the jar, box, or receptacle by the pressure of the cover applied through
packing ring situated between the disc and cover.
a
Reference is to be had to the accompanying drawings forming a part of this
specification in which figure 1 is a sectional elevation of the improvement. Figure 2 is
a plan view of the same. Figure 3 is a side elevation of the jar or box. Figure 4 is
a plan view of the packing ring. Similar letters of reference indicate corresponding
parts in all the figures.
The receptacle A of suitable size and material is provided on diametrically opposite
places with the bevelled lugs B, B, which may be slightly grooved on their bevelled
faces as illustrated in figure 3, or the said lugs B may be formed by a circumferential
bevelled band or shoulder as shown in dotted lines in the same figure.
The cover C adapted to fit on the mouth of the receptacle A is provided on top in
its middle with a post or projection D on which is soldered or otherwise secured one
or more spring bars E placed crosswise and each extending beyond the edge of the
cover C and bent downwards to form arms F, each of which is provided with an
inwardly projecting short lug G adapted to be sprung (by downward pressure on the
outer end of the bar) down over the bevelled lug or shoulder B on the side of the
receptacle and to engage with the under side of such lugs or shoulder as shown in
figure 1, so as to hold the cover C tightly on the mouth of the receptacle A.
The cover is flanged and a packing ring H is inserted between it and a disc I
closing the mouth of the jar, said disc being preferably made of paper coated or
saturated with a suitable substance which is not affected by the contents of the
receptacle. For instance, for certain goods containing a good deal of water, paraffin
paper is employed and for other goods such as paint a paper disc thinly coated with
glue is used.

page_text: The packing ring H is preferably made out of blotting paper, but felt, rubber, or
similar material may be used. It is placed in the cover C before the latter is adjusted
on the mouth of the receptacle and the thin disc I is placed on the upper edge of the
receptacle to which it about corresponds in diameter.
The cover C is then placed over the receptacle A and pressed downward after
which by pressure on the outer ends of the spring bar or bars E the arnis F are moved
downward and their inwardly projecting lugs G snap under the bottom edge of the
lugs or shoulder B.
The cover C presses the packing ring H tightly on the margin of the disc I which
is thus firmly pressed on to the top edge of the receptacle A so that the contents of
the receptacle cannot leak out through the cover and cannot come in contact with the
packing ring H as the disc I is between the ring H and the contents.
The packing ring of soft material may however be a complete disc in which case it
would be coated on the under side to prevent contact of the moisture or liquid in the
can with the cover. In this case the disc 1 is entirely dispensed with.
The cover can be easily removed by prying the arms F outwardly until the
lugs G disengage the lugs B.
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. The combination with a receptacle provided near its mouth and on the outside
with bevelled lugs or shoulder of a cover provided with one or more spring bars
secured to a post or lug on the top of the said cover, the said spring bars extending
over the edges of the cover and downwards to form arms, each having an inwardly
extending lug adapted to engage the said lugs or shoulder on the receptacle when the
cover is placed on the mouth of the latter and the ends of the spring bar or bars are
pressed downwardly, substantially as shown and described.
2. The combination with a receptacle of a cover adapted to be fastened to the mouth
of the said receptacle and a packing ring held in the under side of the said cover and
resting on top of the said disc, substantially as shown and described.
3. A receptacle closure consisting of a cover, a paper packing ring held on said
cover and a disc fitting on the bottom of the said packing ring, substantially as shown
and described.
