COMPLETE SPECIFICATION.
Improvements in Cans or Receptacles for the Transport of Milk, Cream
and Similar Liquids.
I, NIELS CHRISTIAN NIELSEN, of 28, Mariendalsvej, Copenhagen, Manufacturer,
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 improvements in receivers for the transport of milk,
cream and similar liquids; and the object of it is to minimise the chances of
leakage in such vessels and to enable them to be more readily and thoroughly
drained and cleansed to prevent injury to health through putrid residue.
The large cans or receptacles commonly used for the transport of milk, cream and
similar liquids are generally made of several parts jointed together in such a
manner that projecting edges and sharp corners are formed in the interior of
the receptacle. Cans constructed in this manner, besides having a tendency to
leak when they are exposed to hard work, are very difficult to keep thoroughly
clean, as, after having been emptied, the residue of the liquid remains clinging
along the projecting edges and in the sharp corners. This residue is apt to
putrify and thus be injurious to health.
The present invention consists of a can or receptacle for the transport of milk,
cream and similar liquids in which the above-mentioned drawbacks are entirely
obviated, which result is obtained by making the same of only two parts and in
such a manner that the inner surface is entirely smooth and free from project-
ing edges and sharp corners.
In the accompanying drawings:-
-
Figure 1 shows the improved can or receptacle in elevation.
Figure 2 is a vertical section on the line C-D of Figure 1.
Figure 3 is a cross section on the line A-B of Figure 2, and
Figure 4 is a plan view of Figure 1.
The vessel consists of the shell that is made in two pieces, the upper part a
and the lower part b; of the lid and the foot-ring d. The upper part a and
the lower part bare each pressed or shaped out of a single piece from a metal
sheet or plate and jointed together at e with a double fold that is pressed together
as much as possible thus securely interlocking these two edges. In order to
make the inner surface quite smooth, the small annular groove between the upper
and lower part is filled with soldering material g.
The bottom plate is slightly concave internally or bent into a large curve so
that no residue of the liquid may be left behind in such places, around the
circumference for example, where it cannot be easily removed.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is
-
The improved can or receptacle for the transport of milk, cream and similar
liquids, consisting of two parts, an upper part and a lower part each of which

page_text: parts is formed in one single piece from a metal-plate and both jointed together
with a double fold, the annular groove between the upper and lower part of the
shell on the inner surface of the same being filled with soldering material sub-
stantially as and for the purposes described and illustrated.,
