Improvements in Hermetically Closing Metal Boxes for Food, and
other Receptacles, without Injury to such Boxes.
I, ALFRED WILLIAM MARSHALL of 30 and 32 Mortimer Street in the County
of London, Merchant 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 invention has reference to a method of hermetically closing metallic boxes,
whereby the fastening may be very easily removed for the purpose of arriving at
the contents of the box, without at the same time injuring the box. The box, after
being opened, is preserved complete and intact. The invention applies equally to
round, square, oval or other shapes of metallic boxes or of boxes of which the sides
of the lid and lower part are made of metal.
In order to hermetically close the box, the lid is first of all put on to the lower
part of the box and then by preference pressed down. A band of suitable metallic
material is then passed round the box so as to cover the junction of the lid and
lower portion in such a manner as to sufficiently overlap the junction and to prevent
the solder from reaching the line of junction of the lid and lower portion of the
box and thus possibly cause it (the lid) to adhere to the box. One edge of the band
is then soldered to the lid and the other edge to the lower part of the box and the
terminals of the band or part of the band where one terminal overlaps the other,
having been soldered, the contents of the box are hermetically sealed.
I use a band somewhat longer than the circumference of the box, so that one end
projects beyond the other end, after the band has been, as above described, soldered
to the box, and thus a tongue is left which can be used by means of the hand or, if
desired, of a key to draw off the band. When this is done, the box remains intact
and in such a state that it can be opened and closed at pleasure.
In the accompanying drawings, like letters indicate like parts :-
Figure 1 shews a section of a circular, oval or other box B B with the lid A A
in position,
Figure 2 shews a section of a similar box with a lining M M of a metallic or other
suitable band.
Figure 3 shews, in section, the metallic band P P soldered over C C the line of
junction of the lid and lower part of the box,
Figure 4 shews the box of Figure 2 with a similar metallic band P P soldered
over the line of junction of the lid and lower part of the box.
Figure 5 shews, in perspective, a circular box of which the section is shewn in
Figure 3 or Figure 4 and the metallic band P P in position covering the line of
junction CC with the overlapping portion or tongue of the metallic band X X L.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The method of hermetically fastening the lid and lower part of metal boxes or
of boxes with metallic sides, so that the box may be afterwards opened without
injury by means of a metallic band, soldered over the line of junction of the lid and
