COMPLETE SPECIFICATION.
Improvements in Cardboard Cases for Fatty Matter.
I, MRS. HELENE RIEDINGER of 30 Karlstrasse Futtlingen, Germany, do hereby
declare the nature of my said invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement
The object of this invention is folding cardboard or a cardboard box for preserving
and packing for transport, solid fat.
In the accompanying drawings
Figure 1 shows the cardboard box complete, and
Figure 2 shows the same unfolded.
This cardboard serves to pack for transport and to preserve solid fats such as
used in particular for machinery and has very great advantages as compared with
similar cases.
The cardboard is made of a piece of strong paper which has the
form, shown in Fig. 2 being bent over in a suitable manner generally along the
lines, a. b. c. so that the lines d and e are joined together, whereupon
the parts, f, g, h, i and f¹ g¹ h¹ i¹ are folded one over the other, to form the
lid or bottom, after the edges a¹, b¹ have been first cut to the required lengths.
The adjoining parts are then fixed in position by any suitable adhesive means.
In order to remove the lid or cover when using this cardboard the edges thereof
are perforated as shown at k and in the drawings. In order to be still able to
conveniently remove the same when the fat is further used the cardboard walls are
perforated in two or more parts m and n so that when by constant usage the uppe
surface of the fat has sunk below one of these lines the upper empty part of the
cardboard can be readily torn off.
The fat may however ooze through the perforations and in order to prevent this,
the inner part of the cardboard is lined with suitable thick parchment, so that the
fat cannot pass through the same. In order however to obtain the greatest
possible security against any liquid part of the fat permeating through the
cardboard and in particular through the bottom a cork sheet is arranged on the
bottom of the cardboard this sheet having the same size, in cross section as
the cardboard.
The differences and advantages of this cardboard as compared with other similar
devices are :-
1st. The perforations of the edges of the lid or cover and of the walls of the
cardboard in order to be able to detach or separate the parts in question.
2nd. The lining with parchment paper to prevent the passage of fat.
3rd. The use of a cork disc or plate at the bottom of the cardboard for the same
purpose.
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
claim is --
First. A cardboard! made in one piece for transporting and preserving solid fats
characterized by perforations (m, n, and k l) in the walls of the cardboard case
and at the edges of the covers which permit to reduce the height of the cardboard

page_text: according as the fat is being used without preventing the closing of the box thus
shortened.
Second. A cardboard such as above claimed characterized by lining the insido
of the cardboard with parchment as well as by a cork plate or disc. arranged at
the bottom of the cardboard for the purpose of preventing the fat from oozing
through the cardboard.
