WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN BOXES OR CASES FOR
PACKING, PRESERVING, AND MEASURING GRANULAR, PULVERULENT, AND SIMILAR
SUBSTANCES." [A communication from abroad by Paul Lehmann, of Berlin,
Prussia.]
This Invention relates to boxes or cases for packing, and preserving granular,
granulated, or pulverulent substances, such as tea, coffee, flour, rice, colors, and
the like, and has for its object to produce a box, the lid of which will when open
serve as a spout so as to facilitate the pouring out of the contents, whilst a separate
cover, which is placed over the lid of the box when the same is closed, serves for
more tightly closing the latter, and also forms a measure or measuring device, the
hollow part of the said cover being provided with a graduated scale indicating its
capacity.
A box constructed according to this Invention may be of any suitable shape in
transverse section, and is preferably made of sheet metal; it may in some cases'
however be of wood, cardboard, or any other material suitable for the purpose to
which the box is to be applied.
If the said box is rectangular in transverse section it is hermetically closed on
all its sides. In one corner thereof I provide an opening to be closed by a lid
formed or made of a piece of sheet-metal bent into a rectangle so as to form two
wings; one side or wing of this lid is attached to the aforesaid box by means of
a hinge, whilst the other wing thereof is guided by the side of the box in such
manner that a small bent projection provided on said wing and within the box
prevents this lid being thrown back too far. If this lid be thrown open its two
Prine S21

page_text: wings will form a spout for guiding the contents when the box is to be wholly or
partly emptied.
I also provide a separate cover for such box, which cover I prefer to make of
the same material as the box, and it consists of three parts. One of these parts is
of exactly the same shape and size as the top of the box, and has on two sides a
narrow rim bent downwards, whilst the other two sides form wings similar to
those above described.
This cover forms as it were a second lid, and when the lid that is hinged to the
box body is closed this separate cover is placed upon the box in such manner as
to fit over and completely hide the aforesaid hinged lid.
To afford ready and convenient means for exact measurement of the contents of
a box embodying this Invention before these contents are used, the separate cover
is in its interior, that is to say, the space enclosed by its three parts furnished with
a graduated scale, which may be conveniently divided and provided or marked on
all three sides of the cover in any suitable manner.
The box body may be of any convenient shape, for instance, it may be cylindrical
or pyramidal; the hinged may in any case be constructed as above set forth, or it
may be modified in various ways, of which the one hereinafter specified will be a
good example.
I may so construct, the hinged lid that when thrown back it forms a kind of
trough-like spout, and in this case it consists of three parts, one of which forming
the bottom of the spout is attached to the box by means of a hinge, whilst the
other two parts or wings which form rectangles with the former one extend into
the interior.of the box when the lid is closed.
The separate cover for these boxes, whatever may be the shape of the latter are
made so as to conform to the box in each case.

WILLIAM ROBERT LAKE, of the Firin of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. IMPROVEMENTS IN BOXES OR CASES. FOR
PACKING, PRESERVING, AND MEASURING GRANULAR, PULVERULENT, AND SIMILAR
SUBSTANCES." A communication from abroad by Paul Lehmann, of Berlin,

.
This Invention relates to boxes or cases for packing or preserving granular,
granulated, or pulverulent substances, such as tea, coffee, flour, rice, pigments, and
the like; the lid of such boxes or cases when open serves as a spout to facilitate
the pouring out of the contents of, a box or case, whilst a separate cover which
is placed over the lid of the box when the same is closed serves for more tightly
closing the latter and forms a measure or measuring device, the hollow part of said
cover being provided with a graduated scale for indicating its capacity.
The said Invention is illustrated in the accompanying Drawing, in which
Figure 1 is a perspective view of a rectangular box, the lid of which is closed,
the separate cover of the box being shewn detached.
Figure 2 is a perspective view of the said box with its lid fully open.
Figure 3 shews the same with its lid partly open.
Figure 4 is a section of the box shown in Figure 1.
Figure 5 is a perspective view of the said separate cover shewing its interior.
Figure 6 is a perspective view of a round box.
Figure 7 is a perspective view of a box of pyramidal shape.
The eaid box may be of any suitable shape, and is preferably made of sheet
metal; it may in some cases however be of wood, cardboard, or any other material
suitable for the purpose to which the box is to be applied. The box shewn in
Figures 1, 2, 3, and 4 is made of sheet metal; it is rectangular in transverse
section and is hermetically closed on all sides. In one corner thereof I provide an
opening a which can be closed by a lid b. This lid 6 consists of a piece of sheet
metal bent into a rectangle, and is on one side or wing fixed to the aforesaid box
by means of a hinge c, whilst the other sido or wing thereof is guided by the side
of the box in such manner that a small bent projection f keeps the lid from being
thrown too far back. This lid b when thrown open will form a spout.
The separate cover C (Figure 1) also consists of sheet metal, and is made up
of
three parts i, m, n; the part i is of exactly the same size as the transverse section
of the box, and has on two sides a narrow rim bent downward, while the other
two sides terminate in the parts m, n. This cover forms (as it were) a second lid,
and when the lid b is closed it is placed upon the box A in the manner indicated
in Figure 4.
To allow an exact measurement of the contents of such a case or box before they
are used, the cover c is provided internally with a graduated scale 1, 2, 3, 4, 5, 6,
in Figure 5, which scale may have any convenient divisions, and may be on one
side of the said cover only or on all three sides thereof, as may be desired.
In the box of circular transverse section, shewn in Figure 6, and in that of
pyramidal form, shewn in Figure 7, the hinged lid have the same shape as that
above described, but modifications of form applicable to the lids of rectangular
boxes, such as above described, will serve for these forms also. The form of the
lid, as shewn in Figure 7, may serve as an example. This lid when thrown back
forms a kind of trough like spout and consists of three parts o, r, and s; the part o
is attached to the box by means of a hinge, whilst the parts r and s extend into
the interior of the box when the lid is closed.

page_text: The separate cover for boxes or cases of other than rectangular shape must in
each case conform to the shape of the box. As hereinbefore stated, the said boxes
are specially adapted for packing and preserving all kinds of granular, granulated,
pulverulent, or similar substances, and these or other contents thereof can easily be
poured out by means of the peculiarly shaped lid which serves as a spout, and the
contents can easily be measured by means of the separate cover.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent and the manner of performing the same, I wish it understood
that I claim,
First. The box or case for packing and preserving pulverulent, granular, and
similar substances constructed of any suitable material, and provided with a lid or
cover so arranged that when thrown open it forms a spout, as and for the purpose
specified.
Second. Providing the said box or case with a separate lid or cover having an
interior graduated scale, substantially as and for the purpose specified.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Nineteenth day of May, in the year of our Lord One
thousand eight hundred and eighty one.
W. ROB. LAKE. (L.S.)
