Fellow of the Institute of Patent Agents for an Invention of IMPROVEMENTS
IN CASES OR HOLDERS FOR THE PRESERVATION AND TRANSPORT OF ROASTED
'OR PARCHED COFFEE, AND OTHER ALIMENTARY AND AROMATIC SUBSTANCES

PROVISIONAL SPECIFICATION left by the said Ernest de Pass at the Office
of the Commissioners of Patents on the 14th September 1883.
ERNEST DE PASS, of 68 Fleet Street, in the City of London, Fellow of the
Institute of Patent Agents, IMPROVEMENTS IN CASES OR HOLDERS FOR THE
PRESERVATION AND TRANSPORT OF ROASTED OR PARCHED COFFEE, AND OTHER
ALIMENTARY AND AROMATIC SUBSTANCES, Communicated to me from abroad by
Victor Achille Billette, of 17 Boulevard Saint Martin, Paris, France,
This invention has for its object new or improved means for the preservation of
roasted or parched coffee, sugar, and other alimentary or aromatic substances, by
the use of improved cases or holders made of parchment, vegetable or artificial
parchment, or of paper so prepared as to possess the qualities of parchment. These
cases or holders are, by preference, formed in the shape of a tube or cartridge, and
can be hermetically closed, and carried like cartridges.
These parchment cases or holders may contain either coffee, roasted or parched
and simply ground, or coffee covered with a layer of sugar, or mixed therewith,
but they may also be used for the preservation and conveyance of tea, of solid
extract of meat, and of all aromatic substances whose flavour is to be preserved
unaltered, notwithstanding the length of time of transport and the duration of
preservation before being required for use.
The said holder or case is closed at one end, and at its other end it terminates
in flaps, tongues, or indentations. When the case or holder is filled with the
substance, or substances to be preserved and conveyed, these latter are compressed,
and a disc, made of parchment or the like, is placed over the same. The flaps
tongues or indentations are then folded over this disc, and the case or holder is
thus closed.
These holders or cases when closed may be coated with a waterproof solution or
vernigh

ERNEST DE PASS, of 68 Fleet Street, in the City of London, Fellow of the
Institute of Patent Agents IMPROVEMENTS IN CASES OR HOLDERS FOR THE
PRESERVATION AND TRANSPORT OF ROASTED OR PARCHED COFFEE AND OTHER
ALIMENTARY AND AROMATIC SUBSTANCES, Communicated to me from abroad by
Victor Achille Billette, of 17 Boulevard Saint-Martin, Paris, France
This invention has for its object new or improved means for the preservation of
the essential and aromatic properties of all kinds of alimentary substances, and
especially of coffee, sugar, tea, pastes, spices, tobacco, &c, without injury or loss of
aroma, by the employment of vegetable or imitation parchment for forming the
case or holder, which may be of any suitable form, but preferably that of a cylinder,
for the division into separate and daily rations of the coffee and sugar provided for
the soldier on active service.
Cases or holders of vegetable or imitation parchment, made in accordance
with this invention, may contain either roasted or parched coffee ground to an
impalpable powder; or coffee and sugar superposed in powder; or the two
substances mixed together, but they may also be used for the preservation and
conveyance of tea, solid extract of meat, or any other commodities or aromatic
substances of which it is desired to preserve the properties, whatever may be the
place of exportation or the length of time they are to be preserved.
It is unnecessary to point out the practical advantages which result from this
method of preservation, and from its employment for rations of sugar and coffee
destined for an army, as compared with all other methods hitherto in use for
fulfilling these conditions, such as coffee in a paste, in cakes combined with sugar,
or simply in a powdered state wrapped up and enclosed in metallic or other cases.
This system of preservation is carried into effect by means of a case, holder
or envelope composed of vegetable or imitation parchment, impermeable.and
hermetically closed, preferably in the form of a cartridge case.
The accompanying drawing shews by way of example a case or holder constructed
in accordance with this invention.
Fig. 1 is an elevation of a tube A, of impermeable vegetable or imitation
parchment, closed at its lower end B, and Fig. 2 is a plan of a vegetable parchment
disc B, having the same diameter as the inside of the tube A, a vertical and
horizontal section of which are respectively shewn in Figs. 3 and 4.
The disc B, is inserted within the tube, as far as the dotted line C, after which
the indented parts D, which are at the ends of the tube are folded over this disc,
thus hermetically closing the tube.
Figs. 5 and 6 shew in elevation, and plan, the outside of the case or holder,
drawn full size; it is closed at the two ends and is capable of containing within
these, or less dimensions, according to the degree of compression exerted, the
regulation daily rations of powdered sugar and coffee of a soldier on active service.
It is advisable to coat the closed case or holder with a water repelling and
anti-vermin varnish, in order to protect it from the effects of the atmosphere, from
insects, and from moisture, even in the case of accidental complete immersion.
The preparation of the liquid coffee from the coffee thus preserved, is effected in
the Turkish manner, that is to say, by letting the coffee soak in the water subjected
to the heat of a fire until ebullition takes place.
Having thus described the nature of the invention and the manner of carrying
the same into effect as communicated to me by my foreign correspondent I declare
that I claim,
1. The novel method herein described of preserving the properties of coffee,
sugar, and aromatic and alimentary substances in general, such as tea, spices,

page_text: tobacco, etc, by enclosing and compressing them either alone, or superposed, or
combined within impermeable vegetable or imitation parchment cases or holders,
as shewn and described.
2. The employment of impermeable parchment or imitation parchment cases or
holders for the preservation and easy transport of roasted or parched coffee, and
ground coffee, with or without sugar, and other aromatic substances, such as tea,
spices, tobacco, as described.
3. The novel arrangement of vegetable or imitation parchment cases or holders
hereinabove described, for application to the preservation and transport of alimentary
and aromatic substances generally, without loss of aroma.
In witness whereof I the said Ernest de Pass have hereunto set my hand and
seal this Eleventh day of March in the year 1884.
