PROVISIONAL SPECIFICATION.
An Improved Box or Package in which to Transport Butter and
other Edible Substances from Place to Place.
1, EMILY PONTIN, of The Poplars, Pascoe Street, Williamstown, in the
Colony of Victoria, Married Woman, do hereby declare the nature of this invention
to be as follows:-
This invention has been devised for the purpose of dispensing with the necessity
for refrigerating apparatus in transporting butter and other edible substances from
place to place. It consists in a novel construction of box or package by which such
object is accomplished, the main idea of such box or package being the absolute
exclusion of air and heat.
My boxes are made with an inner lining of clean, emooth, non-porous, inodorous,
and tasteless material, such as tiles, which by preference are glazed or vitrified on
their inner face, and must be so truly made as to fit together in such a manner as
to be almost if not entirely airtight. For this purpose I prefer that the tiles should
be rabbeted together. This inner lining I surround by a coat or casing of some
material which is a very bad conductor of heat and for this purpose I prefer to use
paper pulp with or without the addition of powdered charcoal, and which coating
I prefer to make in two parts, the one to fit on the top of the box and the other
on the bottom, and to carefully close their meeting ends so as to make a tight joint.
Around this coating 1 provide.an outer shield or cover of wood which may be of
any ordinary kind.
A box or package so made will preserve its contents so that after a voyage from
one end of the world to the other and through various degrees of temperature the
contents will remain unaltered. By this means there is no necessity for any
refrigerating apparatus to keep the contents of the box or package at any given
temperature, neither is there any necessity for any special care being taken
above that of ordinary merchandise while it is being transported from place
to place.

An Improved Box or Package in which to Transport Butter and
other Edible Substances from Place to Place.
I, EMILY PONTIN, of "The Poplars," Pascoe Street, Williamstown, in the
Colony of Victoria, Married Woman, 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 has been devised for the purpose of dispensing with the necessity
for refrigerating apparatus in transporting butter and other edible substances from

page_text: place to place. It consists in a novel construction of box or package by which such
object is accomplished, the main idea of such box or package being the exclusion
of air and heat.
My boxes are made with an inner lining of clean, smooth non-porous, inodorous
and tasteless material such as tiles, which by preference are glazed or vitrified
on their inner face and must be so truly made as to fit together in such n
manner as to be almost if not entirely air tight. For this purpose I prefer
that the tiles should be rabbeted together. This inner lining surround by
a coat or casing of some material which is a very bad conductor of heat and for
this purpose prefer to use paper pulp with or without the addition of powdered
charcoal.
Around this coating I provide an outer shield or cover of wood which may be of
any ordinary kind.
Referring to the accompanying drawings,
Figure 1 is a horizontal section of a box or package constructed according to this
invention. whilst,
Figures 2 and 3 are vertical sections showing the construction of the top and
bottom respectively of said box.
The same letters of reference indicate the same parts in all' the figures.
A represents the inner lining of clean, smooth, non-porous inodorous and tasteless
material such as tiles, B the coat or casing of some non-conducting material such as
paper pulp surrounding said inner lining, and C the outer cover of wood or other
strong light material which will answer the same purpose.
All the joints are preferably rabbeted as shown in order that they may be
perfectly air tight but I would wish it understood that I do not confine myself
to, the precise construction shown as it is obvious that it may be varied in
many ways without departing from the essential feature of this invention. For
instance the package might be made circular or egg-shaped and the different casings
might be made in halves adapted to be screwed together, or they might be made
cylindrical with lids adapted to be screwed or otherwise fastened upon them as will
be well understood by persons who are familiar with the construction of this kind
of package.
In either case a box or package made as above described with an innermost lining
of tiles or other similar material and with an intermediate casing or lining of some
non-beat-conducting material will preserve its contents so that after a voyage from
one end of the world to the other and through various degrees of temperature the
contents will unaltered.
By this means there is no necessity for any refrigerating apparatus to keep the
contents of the box or package at any given temperature neither is there any
necessity for any special care being taken above that of ordinary merchandise while
it is being transported from place to place.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A box or package in which to transport butter and other edible substances
from place to place, in which there is an innermost lining of tiles or other clean
smooth non-porous inodorous and tasteless material with an intermediate casing or
lining of non-heat-conducting material such as paper pulp between said innermost
lining and the outer box or casing substantially as and for the purposes herein
described and explained and as illustrated in the accompanying drawing..
