Improvements in and relating to Bottles, Jars, and other like Vessels.
for Packing or Storing Goods.
I, ROBERT STERN WIESENFELD, of No. 1,111 East Baltimore Street, in the
City of Baltimore and State of Maryland, United States of America, Gentleman,
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:-
My present invention relates to storing or packing vessels, such as bottles and
fruit-jars, and has for its object certain improvements in construction which will be
fully disclosed in the following Specification and claims.
In the accompanying drawings which form part of this Specification
Figure 1 represents a vertical section of the upper end of a bottle or jar showing
the sealing-cap or cover in position to be applied to the jar ;
Figure 2 a similar view, showing the cap or cover applied to the jar ;
Figure 3 an inverted plan view of the cap or cover, and
Figure 4, a top plan view of the jar.
Reference being had to the drawings and the letters thereon, A indicates the
upper end of a bottle or fruit jar provided with a head a in which is a groove bb,
which in the present instance does not extend all the way around the head, as shown
in Figure 4, forming abutments cc between the ends of the grooves which afford
bearing surfaces for the insertion of a flat pointed implement to remove the cap or
cover. This groove may however extend around the top of the jar if desired.
The inner wall d may be curved outward as shown to guide the vertical flange g
on the inside of the cap or cover B and deflect it outward, thereby giving an initial
outward bend or flare to said flange preparatory to the final bend that is formed in
said flange; or the wall may be vertical part way down and then curved for
the same purpose.
The outer wall e of said groove is undercut as shown in
Figures 1 and 2 to form an overhanging upper edge to retain the cap or cover
by the flange g engaging 'therewith, and the bottom of the groove is curved
substantially as shown to ensure the return bending of the flange g in the groove.
Outside of the groove or grooves b is an annular seat or rebate b¹ for the metallic
portion of the underside of the cover B to rest upon, and inside of the groove is
an annular projection upon which the packing disk i of the cover rests and
forms an absolutely tight joint.
B indicates the cap or cover, the body portion of which is made of soft sheet
metal formed in suitable dies and provided with vertical flanges gg which are
separated by one or more vertical incisions h to facilitate the outward bending
of said flanges.
Within and partly encased by the portion f is a packing disk i which may be
cork or other analogous material used for such purposes.
To apply the cap, it is placed in the position shown in Figure 1 and forcibly
pressed down upon the outer end of the head of the jar by a machine for the purpose
or by means of a block of wood or metal and a blow from a mallet or hammer,
which causes the flanges g to spread in the groove or grooves b and turn up at their
outer ends as shown at & in Figure 2, whereby the cap is securely locked in position
on the jar with the inner edge of the top pressing against the sealing-disk i.
To remove the cap, a flat pointed implement is inserted between the cap and
the upper edge of the jar on one side and the cap raised sufficiently to free
the flange g about half way round when the cap may be readily removed, as the
remaining portion of the flange will readily free or disengage itself from the
wall c of the groove.

page_text: 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
First. A vessel having a groove in the end face of its head, in combination with
a cap or cover provided with a packing disk and a flexible flange or flanges on its
lower surface to engage said groove.
Second. A vessel having an annular groove in the end face of its head provided
with an angular outer wall, in combination with a metallic cap or cover provided
with a packing disk and a flexible flange constructed to enter said groove and
impinge against said outer wall.
Third. A vessel having an annular groove in the end face of its head provided
with inwardly inclined walls and a curved bottom, in combination with a cap or
cover having a packing-disk and a flange engaging the walls of said groove.
Fourth. A cover for vessels, consisting of a packing disk partly encased in metal
and provided with a vertical flexible flange on its under side.
Fifth. A cover for vessels consisting of a packing disk partly encased in sheet
metal, said casing being provided with a vertical flexible flange and an annular
bearing surface outside of the flange.
Sixth. A vessel having a groove in the end face of its head and an annular
projecting seat on the inner side of said groove, in combination with a metallic cap
or cover having a flexible flange on its underside, and a packing disk within said
flange.
Seventh. A vessel having a groove in the end face of its head and annular seats
on both sides of said groove, the inner one of which projects beyond the plane of
the outer seat, in combination with a cap or cover enclosing a packing disk_to
engage the inner seat and provided with a vertical flexible flange, and an annular
bearing surface outside the flange to engage the outer seat.
Dated this 9th day of January 1893.
