PROVISIONAL SPECIFICATION.
A New or Improved Manufacture of Receptacles or Containing
Vessels specially Applicable for Goods of a Perishable Nature.
I, PATRICK MOLYNEUX of 137 Saint Paul's Road, Bow Common, London, E.,
Wharf Superintendent, do hereby declare the nature of this invention to be as
follows:-
My invention relates to a new or improved manufacture of receptacles or containing
vessels specially applicable for containing goods which are liable to damage through
exposure to the air whether such damage be due to the absorption of moisture or gases
or vapours or to the exudation or exhalation from the goods themselves of moisture or
of an essential or other constituent.
In carrying my invention into effect I take as a basis for the said receptacles a pulp
of paper or other suitable fibrous matter and I impregnato or mix this pulp at any
convenient stage of the manufacture with a substance compounded of black oxide of
iron, Portland cement, litharge, methylated spirit, shellac, glycerin and gum arabic.
This material, that is to say the pulp impregnated or mixed with the said substance,
is moulded, by any convenient method at present employed for the moulding of articles
from paper pulp, into receptacles or containing vessels of any convenient size and
shape and when desired the moulds or dies employed are heated.
Dated is outh day of October Lodd.
For the Applicant,
J. G. LORRAIN, M.I.M.E., M.S.T.E., &c.,

COMPLETE SPECIFICATION.
A New or Improved Manufacture of Receptacles or Containing
Vessels specially Applicable for Goods of a Perishable Nature.
I, PATRICK MOLYNEUX of 137 Saint Paul's Road, Bow Common, London, E.,
Wharf Superintendent, 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 :-
My invention relates to a new or improved manufacture of receptacles or containing
vessels specially, though not exclusively, applicable for containing goods which are
liable to damage through exposure to the air, and this whether such damage might:
arise from the absorption of moisture or gases or vapours or from the exudation or
exhalation from the goods themselves of moisture or of an essential or other
constituent.
In carrying my invention into effect I take as a basis for the said receptacles a pulp
of paper, or other suitable fibrous matter; and I impregnate or mix this pulp with
the composition known as Neuxene or Molyneux Composition, and which being
described in the Specification accompanying my Letters Patent No. 6582 of the
year 1887 I need not describe here further than to state that it is composed of methy-
lated spirit, shellac, gum arabic, glycerin and body giving materials such as black,
oxide of iron, Portland cement and litharge.
i
This material, that is to say the pulp mixed or impregnated with the Neuxene or
Molyneux Composition I now mould into receptacles or containing vessels of con- :
venient size and shape. This moulding I effect after the usual manner at present
employed for the moulding of articles from paper pulp by means of moulds and dies.
I have found by experiment that I may advantageously modify the method of
manufacture just mentioned by proceeding as follows. Instead of mixing or impreg-
nating, the pulp with the whole of the ingredients constituting the Neuxene or

page_text: Molyneux Composition in the first place, I mix or impregnate it with a weak solution
of a part only of the said ingredients, that is to say with a weak solution
of shellac in methylated spirit and with or without the addition of gum arabic and
glycerin. A solution of one pound of shellac in twelve gallons of spirit gives good
results, but I have found that the effect is slightly improved by the addition to this
solution of a small proportion of gum arabic, say a quarter of a pound. This gum
may either be added in the forin of a fine powder stirred into the solution or dissolved
in glycerine before addition to the said solution. The pulp thus treated, that is to
say mixed or imprognated with the said solution, is then moulded as above mentioned
into receptacles or containing vessels which are afterwards lined by a coating of
Neuxeno or Molyneux Composition painted on the inside. Soveral such coatings
may be applied one after the other and when desired on the outside as well as on
the inside. When these coatings are dry the receptacles or vessels are ready for use.
I have stated that the moulding is effected in the usual manner at present
employed for the moulding of articles from paper pulp. The ways of effecting this
are well known and need not be further referred to here. It may however be well
to mention that I have found it advantageous to lubricate the dies when in use with
melted butter for the purpose of preventing adhesion of the compressed pulp to the
said dies.
The receptacles or vessels thus formed may be closed by means of lids, stoppers
or the like of any convenient known form and these when put in position may be
secured by a luting or sealing of Neuxene or Molyneux Composition.
I have mentioned the advantage of adding gum arabic to the solution of shellac in
methylated spirit. It is not necessary that this specific gum should be used as I have
found that any ordinary gum answers the purpose and gives good results.
Although I have spoken of Neuxene or Molyneux Composition throughout this
specification I desire it to be understood that I do not limit myself to the exact
ingredients nor to the exact proportions constituting such. The proportions may be
varied within considerable limits and some or all of the ingredients may be replaced
by others having equivalent chemical or mechanical properties.
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
1. The new or improved manufacture of receptacles or containing vessels consisting
in mixing or impregnating pulp with Neuxene or Molyneux Composition and there-
after moulding it into form substantially as described.
2. The new or improved manufacture of receptacles or containing vessels consisting
in treating pulp with a solution of shellac in methylated spirit (either with or without
gum or gum and glycerin), moulding the pulp thus treated into form and thereafter
painting with Neuxene or Molyneux Composition substantially as described.
3. The new or improved article of manufacture consisting of receptacles or con-
taining vessels moulded from pulp mixed or impregnated with Neuxeno or Molyneux
Composition substantially as described.
4. The new or improved article of manufacture consisting of receptacles or con-
taining vessels formed by mixing or impregnating pulp with a solution of shellac in
methylated spirit (either with or without gum or gum and glycerin) moulding the
pulp thus treated into form and thereafter painting with Neuxene or Molyneux
Composition substantially as described.
