Improvements in Cans or Flasks.
I, THOMAS THOMAS, of 4, Glenview Villas, Treharris, in the County of Glamorgan,
Chemist, do hereby declare the nature of this invention to be as follows:-
The invention relates to that class of can or flask commonly used by workpeople
and sometimes called. "Jacks." These cans or flasks have heretofore been difficult
to clean out consequent on the only opening therein being through a narrow neck,
and they have practically been confined in use to containing tea, coffee or other
thin fluid.
:
Now according to my invention I so construct a can or flask that it can be readily
cleansed and can be used for containing either tea or other thin liquid or semi
fluids, soups, or hashes, containing vegetables, meat or gravy.
I construct my improved can or flask. of two parts in the following manner; viz.
one part is in the form of an ordinary can or flask but having no bottom, whilst the
other part is in the form of the body of the flask without the conical upper, part
and neck. These two parts are made to fit each other accurately so that when
one is pushed into the other they shall be practically water tight.
I also provide suitable locking means whereby the two parts may be readily locked
together and unlocked when required.
'
By these means the lower part of the can or flask can be used as a basin, the two
parts can be readily cleansed as the hand and any cleansing article can be readily
inserted, and the can or flask is stronger than those ordinarily in use consequent on
its. having double sides.

the same is to be performed to be particularly described and ascertained in and by

page_text: Now according to my invention I so construct a can or flask that it can be readily
cleansed and can be used for containing either, tea or other thin liquid or semi-
fluids, soups or hashes containing vegetables, meat or gravy.
I will describe my invention with the aid of the accompanying drawings in which
Fig. 1 is an elevation partly in section of a can or flask constructed according to
my invention. Fig. 2 is a sectional view of parts thereof drawn to an enlarged
scale, Fig. 2 is a similar section to Fig. 2 showing a slight modification, and
Figures 3 and 4 are elevations of the two parts of the can or flask separated from
each other.
I construct my improved can or flask of two parts A and B in the following
manner viz. one part A is in the form of an ordinary can or flask but having no
bottom whilst the other part B is in the form of the body of the flask without
the conical upper part and neck. These two parts are made to fit each other
accurately so that when A is pushed into B they shall be practically water tight.
In the drawing the part A is represented with its body a of length to reach the
'bottom of the part B but I would here remark that the body a may be made
considerably shorter.
In order to secure a tight joint between the parts A and B I form the joint a²
between the body a and the conical upper part a¹ to project somewhat more than
is usual and I fix around the lower face of such joint a² a strip of cork or other
suitable packing material 3 by bending the edge of the part a¹ forming part of
the joint a² around said joint so as to press against or clip the packing material
as shown at Fig. 2 or by means of a metal ring a bent around the joint a² and
pressing against or clipping the packing material a³ as shown at Figs. 1, 2 and 3;
thus when the part A is properly inserted into the part B the upper edge 6 of the
latter, which is preferably beaded or folded over as shown, presses against the packing
*material a³.
I also provide suitable locking means whereby the two parts A B, may be readily
locked together, and unlocked when required. For this purpose I provide around
the upper part of the body a a shallow projecting rib or bead as and around the
upper part of the part B I form a corresponding shallow projecting rib b' so that
when the two parts A B are being pushed the one into the other the upper part 6
of part B which is splayed slightly outwards, shall spring over the rib or bead a³ and
the rib b¹ fit over the latter.
Other locking means may however be used.
By these means the lower part B of the can or flask can be used as a basin or
cup, the two parts A B, can be readily cleansed as the hand and any cleansing article
can be readily inserted, and the can or flask is stronger than those ordinarily in use
consequent on its having double sides.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. An improved can or flask formed in two parts, the one fitting into the other in
a practically water-tight manner, substantially as herein set forth and as represented
in the accompanying drawings..
2. An improved can or flask formed in two parts, the one fitting into the other
in a practically water tight manner and having suitable locking means applied thereto,
substantially as herein set forth and as represented in the accompanying drawings.
