COMPLETE SPECIFICATION.
An Improved Box suitable for the Preservation of. Cocoa.
I Wilhelm LUDWIG SCHMIDT of 16, Schiffbauerdamm, Berlin N.W. Agent-
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 relates to a box of pasteboard, celluloid or the like, coated.
in the interior with parchment paper and serving for packing, forwarding and.
preserving cocoa.
In the hitherto generally used sheet metal canisters the cocoa suffers under the
influence of changes of temperature and loses its aroma. Cocoa boxes of paste--
board or similar material which are bad conductors of heat protect the contents
against the effect of temperature changes, but they have the inconvenience, that
the cocoa attracts damp especially when it remains a long time in a damp room..
The said inconveniences are now avoided by the improved cocoa box, as the cocoa
therein has no contact with any metal surface and is sufficiently protected against
damp and other exterior influences by the interposed parchment paper. The
cocoa can therefore be kept good much longer in this box and will retain its.
flavour.
In the annexed drawing Fig. 1 shows the new cocoa box in vertical section and.
in the form of a small cask. Fig. 2 is a plan view thereof.
The box consists of two parts a and b of pasteboard, celluloid, wood etc., which
are slid over a ring r and are joined to one another in such a manner that the
joint flies on the outside of the ring about in the middle of the same.
The edges of the opening o in the upper part a for filling the vessel with cocoa
or removing it, possesses a step like cross section and can be closed tightly with an
exactly fitting cover d. The inner wall of the whole cask is covered with
parchment paper p which can be either slid loosely into the box in the form of
a small bag or fixed on the inner walls, in which latter case the under side of the
cover d is also conveniently covered with parchment paper p. Another form is
shown in Fig. 3 in vertical cross section and in Fig. 4 in plan view. This box is.
formed cylindrically in the same manner.
In the form shown in Fig. 5 in vertical section and in Fig. 6 in plan view the
box has the form of a hollow truncated cone. The two halves a and b are in this.
case chamfered at their edges at f for the purpose of easier joining and fastening.
The box needs not always have a circular cross section but may also be
rectangular as shown in plan in Fig. 7 or square as in Fig. 8.
་
The box may also have the form of a bottle, as is shown in Fig. 9 in vertical.
section. The two halves a & b of the bottle can be connected in this case either
in the manner shown in Fig. 1 or as shown in Figs. 5 and 9. These vessels are
usually made of pasteboard but instead of pasteboard there may also be used any
other material capable of being shaped which is a bad conductor of heat for
instance celluloid or wood.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what L
claim is :-
An improved vessel suitable for reception of cocoa consisting of a tightly

page_text: closing receptacle of pasteboard, celluloid or any other material which is a bad
conductor of heat which receptacle is coated on the inside with parchment paper.
