PETER JENSEN of 33, Chancery Lane in the County of Middlesex ❝ IMPROVE-
MENTS IN THE MANUFACTURE OF BOXES FROM CARDBOARD, AND SIMILAR MATERIALS"
(A communication to me from abroad by Dieudonné Louis Caillat, of Paris, France,
According to this invention boxes are made from cardboard or similar materials
in one piece. The boxes may be of any form such as circular, elliptical, rectangular,
or prismatic, suitable for chemists use, for perfumery, or for any other use.
Heretofore such boxes have been made of several pieces which are united by
strips of paper and paste, and in order to explain the present invention I will refer
to some examples of boxes made in the ordinary way. The lid usually consists of
a disc and a ring of cardboard, which are united by means of a strip of paper glued
or pasted on; such a lid then consists of three parts. The box proper consists of a
disc, an inner ring and an outer ring pasted thereto and which forms the usual
ledge or set off for the lid to fit on; these two parts are united to the disc or
bottom by a strip of paper pasted on. It will thus be seen that this part of the
box consists of four parts. The entire box consequently consists of seven parts.
Now according to this invention the box is made of two pieces only, one for the
body of the box and one for the lid. A disc is cut or stamped out from a sheet of
cardboard to the size required for the box to be made. The cardboard may be
made from pulp of wood, paper, straw or other suitable material; it may be used
in various colours for the inside or the outside of the box, and the cardboard may
therefore be of different colour on its two sides. The disc is then softened in any
suitable manner so as to adapt it for the next process which is that of embossing

page_text: or shaping by means of a die and matrix of the required form. The lid of the box
is made from a disc in a similar manner. The boxes so made consisting of two
pieces only may be coloured and ornamented before or after the embossing in any
desired manner. The boxes may be made with or without projecting rim or flange
at the bottom and at the top of the lid, and the body of the box may be made
with, or without a set off for the lid to fit against.
This invention essentially consists in a manufacture of boxes from cardboard or
equivalent material in one piece instead of as heretofore of several pieces pasted
together and in employing for the purpose of this invention any kind of cardboard
coloured or not on the inside or the outside, the said cardboard being subjected to
a pressing or embossing operation by suitable dies. Boxes so made are very
strong.

PETER JENSEN of 33 Chancery Lane in the County of Middlesex "IMPROVE-
MENTS IN THE MANUFACTURE OF BOXES FROM CARDBOARD AND SIMILAR MATERIALS
A communication to me from abroad by Dieudonné Louis Caillat, of Paris, France.
According to this invention boxes are made from cardboard or similar materials
in one piece. The boxes may be of any form such as circular, elliptical, rectangular
or prismatic suitable for chemist's use, for perfumery, or for any other use.
Heretofore such boxes have been made of several pieces which are united by
strips of paper and paste, and in order to explain the present invention I will refer
to some examples of boxes made in the ordinary way. Boxes are usually divided
into two parts, the cover and the box proper. The lid usually consists of a disc or
bottom a Figure 1 and of a ring b¹ which are united by means of a strip of paper c¹
glued or pasted on, such a lid then consists of two pieces, and even three perfectly
distinct pieces or parts viz. the bottom, the ring, and the band of paper or linen for
uniting the two pieces or parts. The box proper consists see Figure 2, of a disc a,
an inner ring band an outer ring c pasted thereto and which forms the usual ledge or
set off for the lid to fit on; these two parts are united to the disc or bottom by a
strip of paper pasted on. It will thus be seen that this part of the box consists of
four parts or pieces The entire box consequently consists of seven parts.
According to this invention boxes are made only in two parts. For this purpose
a washer or ring is cut of a size in proportion to the size of the box to be made;
this washer or ring may be composed of any sort of suitable material, as for
example of wood pulp, paper pulp, or straw pulp; it may be dyed of different
colours either by aniline or other colouring material so as to form a first ground or
colouring either inside or outside the box or even in the pulp itself; dyed or
prepared sheets may be employed possessing two distinct tints for the interior and
exterior. The ring or washer thus prepared may be softened in any desired and
approved manner, then it is shaped and it is at this point of the manufacture
wherein the invention relates. If the old method of manufacture as shown at
Figures 1 and 2 is examined it will be found that there are four pieces, a, b, c, d for
the box and three a, b, c¹ for the cover. If on the contrary the new process of
manufacture is examined as shewn at Figures 3 and 4 it will be seen that there is
a single piece for the cover and a single piece for the box; that is two pieces
instead of seven if account is taken of the increased cost of workmanship the
importance of the new mode of manufacture will be understood and appreciated.
No particular machine for shaping the boxes made according to this invention is
given as any suitable construction, or tools may be employed the invention con-
sisting essentially in making the box of cardboard without gumming and by any
good mode of shaping either for the cover or for the box proper in such manner as
to obtain the two pieces in two parts instead of seven. It is proposed to employ
either cardboard of a determined shade, and to ornament the boxes afterwards or
to employ cardboard previously prepared on one or both of the surfaces with
decoration or ornament as may be desired. This invention is applicable to boxes
of any form and size either with projecting rim or flange and recess or with pro-
jecting rim or flange and without recess or smooth, or without flange with recess.
Boxes made according to this invention are very strong.
Having now described the nature of the said Invention and in what manner
the same is to be performed I declare that I claim.

page_text: The manufacture of boxes from cardboard or equivalent material in one piece
instead of as heretofore of several pièces pasted together and in the employment for
the purpose of this invention of any kind of cardboard coloured or not on the
inside or the outside, the said cardboard being subjected to a pressing or embossing
operation by suitable dies, all substantially as set forth.
In witness whereof I the said Peter Jensen have hereunto set my hand and
seal this Seventh day of February in the year of our Lord one thousand
eight hundred and eighty three.
