WILLIAM ROBERT LAKE, of the Firin of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN DISHES OR TRAYS, CHIEFLY
DESIGNED TO BE USED FOR HOLDING BUTTER, LARD, AND SIMILAR MATERIALS.'
A communication from abroad by Chalmers Ingersoll, of Beloit, Wisconsin, United
States of America, Manufacturer.
The want of some suitable and cheap receptacle for the use of retail dealers in
butter, lard, and other like substances, has long been acknowledged: Sheets of paper
are unsuitable for packages of this kind, while ordinary dishes are too expensive.
The object of my Invention is to provide a dish or tray adapted to the above use,
and so inexpensive that it may be furnished to dealers at a cost not much above
that of wrapping paper.
The said Invention comprises a small shallow dish, plate, or tray made from
finished paper board or sheets of paper bent into any desired shape, but always with
inclined or flaring sides.
In the accompanying Drawing,―
Figure 1 is a plan of one of my improved dishes; Figure 2 is a cross section on
the line x, x, Figure 1; and Figure 3 illustrates a modification in the construction
of these dishes herein-after described.
In carrying this Invention into practise, the paper may be brought into the
required shape by several methods.
I prefer however to take finished paper board of any suitable description, or a
paper sheet of the requisite size and thickness, lay it in or over a mould of the

page_text: requisite form, and bring down upon it à stamp or die to strike up or press the
sheet into the desired shape for the plate. Straw board is well adapted to this
purpose, and the stainping may be done without dampening the board; but usually
it is better to steain or otherwise slightly dampen the sheets before they are put
into the dies.
Figures 1 and 2 represent a dish made in this manner; but I do not limit myself
to this mode of manufacturing the above-named articles.
The sheet of paper board may be bent into the form of the dish in any suitable
manner, the completed articles remaining essentially the same.
In the modification of my Invention, illustrated in Figure 3, the sheet of card or
other board is slitted at each corner down to the line along which it is to be bent
to form the sides of the dish. The sides are then bent up into an inclined or
flaring position, as shown in the Drawing, the corners being allowed to slip by each
other, in which position they may be gummed together or otherwise fastened by
any suitable means.
If necessary the under side of the board may be scored slightly along the lines of
the bend to facilitate the operation of bringing the sheet into the desired shape ;
and the bending may be effected upon a former whenever it is necessary.
Any other method of bringing the sheet of board into the shape desired, and
holding it, may be employed without departing from the essential features of my
Invention, which relates to the dish, plate, or tray, and not to the mode of
producing it.
A dish or tray thus made of paper material, which has heen pressed or rolled into
a solid sheet form, is comparatively strong, of uniform thickness throughout, and
will present a smooth and even surface on both sides. In all of these particulars it
differs from articles made by pressing paper pulp in dies, which I am aware has
been already practised.
.
In case the dish is struck up in dies it will be perfectly tight, and when
constructed by slitting the edges, as described, the joints are made tight by gumming
or pasting, thereby preventing leakage.
The plate or dish may be lined, if it is desired, to keep the butter, lard, or other
substance from coming in contact with the board; or the inside of the dish may be
coated with any suitable waterproof solution or enamel.
A material composed of paper and wood combined, by uniting thin sheets of wood
and paper board in any suitable manner, may be employed for the construction of
the said plates, dishes, or trays if desired.
The wood may be arranged either on the inside or outside of the dish or plate.
In all cases however the dish or plate should be made from one piece of the
board or other material to obviate the necessity of joints in uniting two or more
pieces together. Pie plates and other very shallow dishes may be produced in the
same way.
Further modifications of my Invention are shewn in the following Figures of the
Drawing:-
Figure 4 is a plan of a blank for making a circular dish according to my
Invention.
Figure 5 is a plan drawn to a reduced scale of a dish made from the said blank.
Figure 6 shows a blank for a square dish.
Figure 7 is a plan of a dish made from this blank.
Figure 8 shows a modification in the cutting of a square blank.
And Figure 9 is a section across one end of the dish made from the said blank.
In Figure 4 A is a blank of circular form consisting of a single piece of paper or
paper board.
In making a dish from this blank the outer portion a must be bent
up along the line a¹; and, if it is desired, the blank may be scored along this line
to facilitate the turning up of the side.
Slits a are cut in the outer section a extending from the edge of the blank to
the line of the bend al, and a short circular slit all is made on the line a¹ extending
from the inner end of the slit a". These slits should be made in sufficient number

page_text: around the disc to enable the sections of the outer or annular portion a to be bent
up readily along the line a¹. When this is done it is evident that at each slit there
will be a short end or tongue, which is free to pass by or overlap the contiguous
portion of the section, thereby compensating for the bend in the blank, preventing
crimping, and furnishing means for fastening the turned-up edge in position by
rivetting, glueing, or otherwise securing the overlap to the other portion. The
edge is intended to be secured in a flaring position to give the finished article the
shape of a dish or tray.
In Figure GB is a rectangular blank, which is to be bent along the lines b in
forming the dish, and may be scored along the said lines if desired. At each
corner of the blank, slits b' are cut diagonally to the line of the bend, extending to
the point where the side and cross bends meet. The outer sections 611 are then
bent up along the lines b', and it is evident that at the slit corpers the ends of the
sections will overlap each other and prevent crimping, as above described. These
overlapped ends are fastened together by pasting, or in any other suitable manner
to form a small rectangular dish or tray with flaring sides, as shewn in Figure 4.
In Figure 8 I have shewn a modification of the slitting of the blank; the slit b
being on a line with one of the bends, instead of in a diagonal direction, as shewn
in Figure 6, and the slit is necessarily commenced a slight distance from the corner.
In other respects the blank is of the same general character as that shewn in
Figure 6, and the dish is formed in the same manner; the free end or tongue at the
corner partly overlaps its contiguous section, and is secured thereto, as described
above.
In making the dish from either of these blanks, a former may be used if desired,
but it is not absolutely necessary..
The dishes may be manufactured by hand, or machinery may be designed for
this purpose. By this mode of construction a cheap and serviceable dish may be
made sufficiently strong and durable for the purposes indicated, and at the same
time so light in weight as to be unobjectionable.
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 do not limit my Invention to the use of paper material, as it is equally applicable
to other material, which may be cut and bent in the manner above described, and I
claim a shallow vessel or receptacle of the forin of a dish, plate, or tray constructed
of finished paper, paper board, or other like material bent into the desired shape, as
shewn in Figures 1 and 2 of the Drawing, or in either of the modifications thereof,
as above set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Eleventh day of July, in the year of our Lord One
thousand eight hundred and seventy-seven.
