GEORGE LANDALE CUMBERLAND, of 40, Southampton Buildings in the County
of Middlesex "IMPROVEMENTS IN METAL CASES OR CANISTERS FOR HOLDING
TEA OR OTHER ARTICLES
دو
This invention relates to metal cases or canisters made preferably of tin plate,
and used for the purpose of storing and carrying tea or other articles, and
it has for its object a novel method of constructing such cases or canisters so
that they are very easily packed for carriage when empty, and occupy very little
space, whilst when filled their covers are simply and easily attached or removed,
and are very strong and durable and easily made air-tight, whilst the entire
apparatus is cheap and easily made.
In order to put my invention in operation I make a case of tin plate of any
suitable size and strength, rectangular and preferably nearly square in plan, but
somewhat smaller at its lower end which is closed, than at its upper end which is
open to receive a moveable cover as hereinafter described.
The edges of the upper open end of the case I form to receive the cover in the
following manner.
The edges of two opposite parallel sides I bend outward and downward until
they are nearly parallel to the sides to which they are connected.
The edge of the third side I bend outward until it is parallel with the top of the
case, and the edge of the fourth side I also bend outward until it is parallel with
the top of the case, but I then bend its outer edge upward and backward until it is
also parallel or nearly so with the same plane.
The cover for the case I form of a rectangular sheet of metal preferably tinplate
of suitable size and thickness, and I bend two of its parallel edges first at right
angles downward and then their lower edges inward and up so that their edge
reaches nearly to the lower surface of the cover.
The width between these parallel edges so formed is such that they can be
made to slide over the parallel turned down edges of the two sides of the case first
described. The third or back edge of the cover I turn down and then inward so
that it fits over the third edge of the case which has been bent outward as already

page_text: described; and the fourth or forward edge of the cover I leave flat so that when in
its place it fits into the edge of the fourth side of the case which has been turned
outward and then backward as already described.
Instead of the parallel edges of the case being turned outward and downward as
first described they may be turned inward and downward, the corresponding edges
of the cover being turned outward and up to fit them.
And sometimes, instead of square I make the cases hexagonal the covers being
made to correspond.
By the method of construction described the cases when empty and the covers
removed, can be fitted one into another so as to occupy very little space in carriage,
the loose covers being preferably placed inside them; they are very strong, cheap,
and easily made, and are well adapted for containing tea, or other articles
requiring protection from damp or other injury. A ring or other handle may be
fixed to the cover.
