An Improvement in Boxes for Preserving Butter and other "Dairy
Produce and Perishable Goods, and especially whilst being
Transported from Place to Place.
I, JOHN Pow BOYD of 44 Thistlethwaite Street, South Melbourne in the Colony
of. Victoria, Carpenter do hereby deolare 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 an improvement in boxes for preserving butter and
other dairy produce and perishable goods and especially whilst being transported
from place to place either by sea or on land and without their having to be kept in
a refrigerating or cool chamber or car. The box proper or outer case or package
is made preferably of wood as ordinarily, the improvement consisting in lining the
whole of the interior walls or surface of the box with earthenware tiles and
which being of a non-conducting nature when the butter or other produce is placed
between them and the cover of the box or package secured or hermetically sealed
the produce will remain for the ordinary requisite length of time at as nearly as
possible the temperature it registered when placed therein or packed and hence it
will be preserved until the box or package is opened. An advantage in using tiles
for the above described purpose, in the export trade, is that when the boxes reach
their destination and are opened or broken up the tiles after being taken out
are still of value for Hoors, linings or any other of the various purposes for which
they are used.
In order that my invention may be well understood I attach a sheet of drawings
hereto in which
Fig. 1 is a broken perspective view of a box, case or package lined with earthen-
ware tiles in accordance with my invention and Fig. 2 a plan of same with cover of
outer box or case removed.
In these figs. A are the sides, B the bottom and C the cover or top of the outer
case or package and which is of any ordinary construction, D are the side, D' the
bottom and D the top earthenware tiles forming the inner walls of the box. As
shewn in the drawing the bottom tile D' is made to fit neatly within the sides A of
the outer case and laid upon its bottom B the side tiles D standing upon the bottom
tile D. Two of said side tiles are shewn rabbetted at d to receive the other two
sides so as to retain the whole of the side tiles D in position whilst the top tile D'
is supported upon the top edges of the side tiles D. The outer case is made deep
enough to be about flush with the top surface of the top or cover tile D³.
When the butter or other produce has been packed in the box between its tiled,
walls the top tile D is laid in position and the cover C of the box or package is
nailed or otherwise secured.
Fig. 3 is a broken plan shewing a modified means for securing the side tiles D in
position, two of said side tiles D having grooves formed in them to receive the teuon
or tongue d' formed on the ends of the other two side tiles.
Fig. 4 is a plan of one corner of the box or package shewing a further
modification. In this instance the side tiles D are mitred at their meeting edges d³
to retain them in position within the box, whilst Fig. 5 is a sectional view of one
angle of the bottom of the box case or package and shewing that the bottom tile D'
may have a rabbet or recess d³ formed around its edge to receive the lower edges of
the side tiles D and from this figure it will be obvious that the top or cover tile D'
can be constructed in a similar manner.

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 :-
My improvement in boxes for preserving butter and other dairy produce and
perishable goods consisting in lining the interior walls of the box, viz. the sides,
top and bottom with earthenware tiles substantially as described and as illustrated
-in my drawings.
