An Improved Closing Device for Boxes, Tins, and the like.
I. RICHARD KIRSCH, of Zarnikan near Riga in the Empire of Russia, Decorative
Painter, 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 relates to the means for closing tins boxes and such like and has for
its purpose to provide an effective closing device which can with facility be applied to
all sizes of such receptacles and removed without any injury to the latter when
opening the same.
The essential and peculiar feature of the invention consists in inserting between the
side or sides of the tin or box and the outer rim of the closing plate or cover a layer
constituting the closing of the receptacle and being easily removable without any
cutting of or other injury to the side or sides and cover thereof.
Referring to the accompanying drawing
Fig. 1-10 illustrate the improved device as applied to oblong and cylindric
receptacles.
The closing means proper is a piece of wire a of suitable cross section which, when
closing the tin or box, is placed between the cover A or closing plate rim and the
side or sides d of the receptacle and secured in this space, so as to fill the same by
means of solder, Figs. 1. 2. 3 and 10.
Said piece of wire slightly exceeds in length the circumference of the closing plate
or cover A of the receptacle so as to leave a projecting piece e, sufficiently long to be
seized when undoing the closing, by means of a convenient tool as suggested in
Figs. 4, 5 and 10, and removed from its groove to disconnect the cover from and
open the receptacle. The wire may be wound up as shewn or torn out of the
groove.
The closing of the cylindric box illustrated by Figs. 1, 2 and 3 is shewn as effected
by means of a solid wire a of round cross section, while, in the oblong receptacle
Figs. 4-6, a wire a¹ of triangular cross section is employed, which is inserted with
its downwardly directed closing edge between the sides and cover, thus ensuring
tight closing of the receptacle.
a
Figs, 7, 8 and 9 illustrate the improved node of closing as applied to corned beef-
and similar tins, a thin tube a" which may have any suitable cross section, being
employed as a substitute for the solid wire referred to.
As elucidates from Fig. 10, the closing wire a may also be soldered into and twisted
or wound out of a corresponding groove formed on the side or sides of the receptacle
by the cover A overlapping the rim thereof and having an outward bend / while a
projection K is provided on the box.
A strip or other suitable device Figs. 4 and 5, may be attached to the receptacles
for the purpose of holding the opening tool g, the latter and also the projecting
extremity of the wire or tube being so placed as not to interfere with the good
shape, handiness or packing of the boxes; Figs. 4 and 5.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
A closing device for tins, boxes and similar receptacles consisting of a wire or
tube a, a al of convenient cross section so inserted and soldered between the rim of

page_text: the closing plate or cover and the rim or side or sides of the receptacle as to be
removable for disconnecting the latter from its cover substantially as and for the
purpose set forth.
