An Improved Milk, Can or Container.
We, THE FRIERN MANOR DAIRY FARM LIMITED and CHARLES HENRY TAYLOR,
Managing Director, both of 20, Farringdon Street, in the City of London, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
This invention relates to an improved vessel for the retail delivery of milk and it
consists of a vessel or can of tin-ware specially constructed as hereafter described so
as to ensure great strength to enable it to resist the rough usage to which such
vessels are subject in daily use, and which is adapted to be closed by an air-tight
stopper never heretofore applied to such vessels, whereby to adapt the vessel for the
reception of sterilized milk and guard against the contamination of the milk by
atmospheric impurities and ensure that the nilk whether sterilized or not shall be
delivered to the consumer in its original state of purity.
Heretofore the milk cans generally used for the retail delivery of small quantities
of milk have merely been provided with a loosely fitting lid or cover which in no
way protects the milk from atmospheric contamination, whereas by the construction
now adopted and the provision of a hermetically-fitting stopper all of the objections
to the cans now used are obviated.
The invention is illustrated in the accompanying drawings forming part of this
Specification wherein Figure 1 is an elevation and Figure 2 a vertical section on
line 11 Figure 1, of the can.
The can is made of tinned sheet iron and is of bottle shape. It is composed of two
main portions (A) and (B) forming the neck and body and a third portion (C) forming
the rim of the mouth and a seat for the stopper.
The two main portions (A, B) are each formed of one single piece brought to
the form represented, by stamping or drawing in dies. The upper portion (A) com-
prises the neck (a) of reduced. diameter, the shoulders (a), and the upper part (a²)
of the body whilst the part (B) comprises the lower part (b) of the body and the
bottom (61) which is in one with the sides. These two main portions are united
by a circumferential joint. (D) formed by outwardly projecting flanges (d, d')
formed on the parts (A, B) in the operation of stamping or drawing in dies, the
flange (d) on the upper half (A) being of greater width than the flange (d¹) on the
other half, the flange (d) being turned over the flange (¹) as shewn, by stamping or
"spinning" and the joint being completed by soldering. The form and position
of this joint are such as to greatly stiffen the body portion of the can and prevent it
being flattened or rendered mis-shapen by rough usage whilst the inherent strength
of the joint made by the overlapping flanges is such that the joint is in no way
dependent on the solder which merely serves to render the joint liquid- and air-tight
so that leakage of the joint by any violent usage to which it may be subjected
is impossible. The mouth portion (C) of the can is also formed by stamping or
drawing in dies. It comprises a circumferential band portion (c) which fits closely
around the neck portion (a) and is united thereto by soldering and is provided with
a beaded lip (c) formed by turning the metal over a wire core in the ordinary way of

page_text: working tin plate. This lip portion projects above the edge of the neck portion (a)
which it surrounds so as in conjunction with such edge to form a seat for the recep-
tion of a stopper such as that shewn at (E) formed of porcelain or suitable metal,
provided with a rubber packing ring (e) and secured in place by a "bail" or yoke of
stout wire (F) whose ends are pivoted at (f.) to a bent lever bow or frame (G) whose
in-turned ends (g) are pivoted in metal bearing bosses (h) on the neck of the can, so
that when the parts are in the position shewn in Figures 1 and 2 the stopper will be
pressed tightly into its seat and securely retained whilst admitting of being thrown
back to the position shewn in dotted lines in Figure 1 for the purpose of pouring
out the contents. In order to ensure the permanent connection of the stopper with
the can, the ends of the pivots (9) of the bent lever frame (G) are bent as
shown at g¹ so as to be permanently engaged within the bosses (h). These are
conical stampings of tin plate or other metal of the form shewn in section which
are soldered to the sides of the neck (a).
The mouth of the can, although preferably formed by a separate portion (C) as
described, might however be formed in one with the neck (a) by spinning over the
edge of the latter as will be readily understood.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. The manufacture of a bottle-shaped can or receptacle for milk, of two main
portions stamped and drawn in dies and united by an outwardly projecting circum-
ferential overlapping flange joint substantially as specified.
2. The manufacture of a bottle-shaped can or receptacle for milk, of two main
portions stamped and drawn in dics and united by an outwardly projecting circum-
ferential overlapping flange joint, the upper portion having a beaded rim united
thereto to form the mouth of the bottle and a seat for the stopper substantially as
specified.
3. The combination with a can or receptacle constructed as described, having bosses
soldered to the neck, of a stopper provided with a bail and lever fastening such as
described the pivotal ends of the lever being bent at right angles so as to be retained
in permanent engagement with the bosses in which they are pivoted as described.
