PROVISIONAL SPECIFICATION.
Improvements in Packing Semi-fluid Substances, such as Soft Soap
and other Caustic Semi-fluid Substances and the like, and in
Boxes therefor.
I, CHARLES MASON, of the Chiswick Soap Company, of Chiswick, London, W.,
Soap Manufacturers, do hereby declare the nature of this invention to be as
follows:-
My invention relates principally to. boxes for packing and sending out semi-
fluid or viscous substances, more particularly those of an alkaline nature such as
soft soap, in retail quantities, and so that the boxes may be protected from the
caustic action of the contents.
For this purpose boxes are required which can be produced at a very small
price; they are not required to be absolutely watertight because the soft soap is
extremely viscid, but it is necessary that they should resist the chemical action of
the soap, and while requiring to be sufficiently strong to bear handling and
transit, they are not required to be otherwise of great durability.
According to my invention I make the box of pulp-board, paste-board, mill-
board, or the like material, which I protect internally with a metallic lining as
hereinafter described.
The body of the box is made of a slip of thin pulp-board or the like which I
bend round a mould and join the ends with a moisture resisting glue or cement,
or otherwise and with or without one or more wire stitches or binders.
The bottom and lid I make each of a disc of the same material the edge of
which I turn up in a suitable mould and press, so that it will exactly fit over the
body of the box, and I may emboss at the same time on the lid or bottom some
ornamentation, pattern, or device, such for instance as the proprietor's trade mark,
together with one or more annular corrugations, ridges, or the like, which add
to the stiffness of the piece.
The bottom may be fixed on the body of the box with the like glue or cement
or otherwise and the top fits over the upper end of the body of the box.
The lining I make of very thin sheet metal such as sheet iron either tinned or
not or of other sheet metal which may be drawn in the form of a tube or cylinder
or the edges of which I may join by means of a folden joint or of solder or
otherwise.
When this is filled with a viscid substance such as soft soap or the like it may'
be covered with a disc of waxed or paraffined paper and further the internal
surface of the lid may be protected by a coat of wax-or instead of--or in addition
to this, a metal disc may be interposed between the top of the material and the
lid itself.
According to the nature of the contents intended to be placed in the box the
prefer to
kind of metallic lining must be selected, for instance, for soft soap,
use iron either tinned or unprotected.
It will be readily understood that boxes as above described can be produced at

page_text: an exceedingly low cost and that they nevertheless possess in a remarkable degree
the peculiar combination of qualities required for the purposes stated.

Improvements in Packing Semi-fluid Substances, such as Soft Soap
and other Caustic Semi-fluid Substances and the like, and in
Boxes therefor.
I, CHARLES MASON, of the Chiswick Soap Company, of Chiswick, London, W.,
Soap Manufacturers, 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:
-
My invention relates principally to boxes for packing and sending out semi-
fluid or viscous substances, more particularly those of an alkaline nature such as
soft soap, in retail quantities, and so that the boxes may be protected from the
caustic action of the contents.
For this purpose boxes are required which can be produced at a very small
price; they are not required to be absolutely watertight because the soft soap is
extremely viscid, but it is necessary that they should resist the chemical action
of the soap, and while requiring to be sufficiently strong to bear handling and
transit, they are not required to be otherwise of great durability.
My invention will be best understood by reference to the accompanying draw-
ings in which
Fig. 1, is an elevation partly broken away and
Fig. 2, a plan, also partly broken away, of one construction of my improved
box, and
Figs. 3, and 4 are views, respectively similar to Figs. 1 and 2, of a modified
construction of the box.
According to my invention I make the box of pulp-board, paste-board, mill-
board, or the like material, which I protect internally with a metallic lining as
hereinafter described.
The body A of the box is made of a slip of thin pulp-board or the like a which
I bend round a mould and join the overlapping ends a' with a moisture-resist-
ing glue or cement a² Fig. 1, or otherwise and with or (as represented in the
drawings) without one or more wire stitches or binders.
The bottom B and the lid C I make each of a disc of the same material viz. pulp-
board or the like the edge of which I turn up in a suitable mould and press, so
that it will exactly fit over the box-body A and I may emboss at the same time
on the bottom or lid some ornamentation, pattern, or device, such for instance
as the proprietor's trade mark, together with one or more annular corrugations,
ridges, or the like as indicated at b and c which add to the stiffness of the piece,
The bottom B may be fixed on the box-body A with the like glue or cement
(as at 6) or otherwise and the top fits over the upper end of the body of the box
so as to form a removable cover.
The lining I make of very thin sheet metal such as sheet iron either tinned or
not, or of other sheet metal which may be drawn in the form of a tube or cylinder,
or the edges of which I may join by means of a folden or other joint, or of solder
or otherwise, the bottom of the said tube or cylinder being practically closed by

page_text: a metal disc d, which may be secured in position by solder or otherwise, or merely
left loose.
When this box is filled with a viscid substance such as soft soap or the like
it may be covered with a disc of waxed or paraffined paper e and further, the
internal surface of the lid may be protected by a coat of wax or instead of-or
in addition to this, a metal disc may be interposed between the top of the
material and the lid C itself.
In the modification shown in Figs. 3 and 4 the bottom B and lid C are formed
of similar dished" metal discs having annular grooves at their edges to fit
upon the edges of the box-body A. The bottom B is rigidly secured to the box-
body by being tightened (by spinning or otherwise) upon the lower edge thereof,
while the lid C is adapted to fit upon the upper edge of the box-body so as to be
capable of being readily removed therefrom when the box is to be opened.
According to the nature of the contents intended to be placed in the box the
kind of metallic lining must be selected, for instance, for soft soap, I prefer to
use iron either tinned or unprotected.
It will be readily understood that boxes as above described can be produced at
an exceedingly low cost and that they nevertheless possess in a remarkable degree
the peculiar combination of qualities required for the purposes stated.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is :-
(1) For packing semi-fluid or viscous substances the employment of a box
constructed substantially as herein before described.
(2) For packing semi-fluid or viscous substances the combination with a box
formed of pulp-board, paste-board, mill-board or like material of a metallic lining
substantially as herein before described.
(3) A box for packing semi-fluid or viscous substances constructed substantially
as herein before described and illustrated in Figs. 1 and 2 of the accompanying
drawings.
(4) A box for packing semi-fluid or viscous substances constructed substantially
as herein before described and illustrated in Figs. 3 and 4 of the accompanying
drawings.
