An Improved Duplex Wrapper for the Wrapping of all kinds of
Oily or Unctuous Matter.
We, ARTHUR BILLING of the firm of Martin Billing, Son, and Company, of
Livery Street, in the City of Birmingham, Manufacturer, and JOSEPH PARKER of
Murdock Road, Handsworth, near the aforesaid City, Traveller, do hereby declare
the nature of this invention to be as follows:-
Our invention has reference to coverings or wrappers, used for the wrapping of
all kinds of oily or unctuous matter, but principally used by grocers, and provision
dealers, for the wrapping of general provisions.
It has long been the custom for the wrapping up of all unctuous provisions, to
use transparent grease proof coverings or wrappers, but it is also necessary owing
to the unsightliness of the parcel, when wrapped, to use secondary wrappers or
outer coverings of ordinary paper.
The object of our invention, is to make a paper wrapper or covering, with a
grease-proof inside lining or surface, for the wrapping of all kinds of oily or
unctuous matter.
In carrying out our invention, we take a sheet or sheets of any suitable kind of
ordinary non-grease-proof paper, preferably in sizes of 30 inches by 20 inches, and
a sheet or sheets of vegetable parchment paper of a like size as the aforesaid
ordinary paper sheet or sheets.
The said sheet or sheets of vegetable parchment paper, and the aforesaid sheet
or sheets of ordinary paper, are then cemented or consolidated together, by pasting
and pressing, and other suitable means.
The sheet or sheets consolidated together as aforesaid, are then dried, and after
the creases have been taken out by the ordinary rolling process, they are cut into
smaller sheets, of sizes required.
By this method we make a duplex wrapper, or wrappers, having a vegetable
parchment, and thoroughly grease-proof inside lining, and an outside surface of the
ordinary kind of paper..
It will be seen, that in wrapping-up any oily or unctuous matter with wrappers
made according to our invention, a secondary or outer wrapper is not needed, which
materially reduces the cost, and is a great saving in time.
By this method of combining and forming a parchment lined grease-proof duplex
wrapper, the curling of the parchment when exposed to the air, as in the case of a
wrapper of parchment, used alone, entirely avoided.
Although we have described our invention only in connection with a grease-proof
paper wrapper, yet it is also applicable to all kinds of boxes, into which is placed
any kind of oily or unctuous matter.
In the case of boxes, a sheet or sheets of grease-proof parchment, and a sheet or
sheets of tough cardboard would be consolidated together, in the same manner, as
in the case of wrappers, and would then be made into cardboard boxes, with a
grease-proof in the ordinary manner.
Or the parchment may be made to form a grease-proof lining to a wooden, or
other box.

An Improved Duplex Wrapper for the Wrapping of all kinds of
Oily or Unctuous Matter.
We, ARTHUR BILLING of the firm of Martin Billing, Son and Company of
Livery Street in the City of Birmingham Manufacturer, and JOSEPH PARKER of
Murdock Road, Handsworth, near the aforesaid City, Traveller, 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 the wrappers, coverings, or holders, employed, in the
wrapping-up, covering, and holding, of unctuous, or fatty matters, principally sold
by grocers, drysalters, and the like.
Usually, unctuous matters, such as are sold by traders, as described, are first
wrapped in a grease-proof paper, and then in a wrapping or covering paper, in
order to cover up, or conceal the unsightliness of the grease-proof-paper.
Our invention has for its object, the combining together in one article, or in one
sheet of paper, a grease-proof-wrapping-up paper, and a covering or enveloping
paper, or in other words, a wrapping-up paper or cover, with a grease-proof lining.
In carrying out our invention, in the formation of a double sheet wrapper, we
take a sheet of absorbent, or non-unctuous proof paper, of any suitable kind and
size, and a sheet of vegetable-parchment paper, or other like grease-proof material,
and paste or unite the said sheets of paper together, which are subsequently pressed
or rolled out, and finished, and if necessary printed, in any desired manner, hence
an ordinary wrapping-up paper, with an unctuous-proof-lining.
The finishing of this compound sheet, is preferably performed, after the drying,
or partial drying of the same, and which said finishing, removes by a rolling
process, all creases, and gives finish. The sheets are subsequently cut up into sizes
as may be required for use.
Instead of a compound grease-proof-wrapper composed of an unctuous-proof
interior, and an exterior of ordinary paper, we may place the unctuous or grease-
proof-lining between inside and outside ordinary papers, so that the unctuous-proof-
paper, does not come in direct contact with the article wrapped.
By combining together two or more papers as described, and making them
integral one with another, it is thus understood, that a considerable advantage is
obtained, inasmuch, as considerable time in single wrapping is saved, as a commodity
has only to be wrapped in one paper, by the employment of a compound-sheet,
instead of being wrapped twice, as when single sheets, are employed; and further,
vegetable parchment sheets when employed per-se, are troublesome to wrap,
consequent on the same being curled, distorted, or buckled, in figure, caused by
exposure to the air, and change of temperature.
Although we have described our invention in connection with a grease-proof-
compound wrapper, yet the same may be employed in connection with an enclosure
in the form of a box or casing; in this case, the unctuous-proof material, is united
or consolidated, by pasting or otherwise, to the inside parts of card-board or stiff
paper to form the said enclosure.
Figure 1 of the accompanying drawings represents an unctuous-proof-compound
sheet.
Figure 2 is a section of the same, showing the unctuous-proof material on the
inside, united to an ordinary sheet of wrapping paper on the outside.
a is the sheet of plain paper, and is the unctuous-proof lining thereof.
Figure 3 represents a paper box, the material of which, is provided with an
unctuous-proof lining.
Figure 4 is a cross section of the same.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First In a grease-proof wrapper, sheet, or the like, consisting of two or more
united together sheets of paper, or like material, one unctuous or grease proof, and
the other plain, and of absorbent, or ordinary paper, hence a compound sheet, as
and for the purpose, as described and set forth.
Secondly In a grease-proof box or enclosure, consisting of cardboard or stiff
paper, provided with a grease or unctuous proof lining, united to, or made integral
with, the outside material or walls of the said box or enclosure, substantially as
described and set forth.
