Improvements in Hermetically Sealed Packages for Packing and
Storing Semi-solid Substances.
I, JOHN WILLIAM HASBURG, of 588, Fullerton Avenue, in the City of Chicago,
County of Cook, and State of Illinois, United States of America, Manufacturer,
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 fol-
lowing statement:—
¦
My invention relates to a novel construction in a package or receptacle for
packing and storing semi-solid substances, particularly gold paint, and other
substances of a similar nature which it is desired to retain in viscous or semi-
solid form and protected from the admission of impurities, so as to keep it in
the best possible condition for the consumer, the object being to provide a
simple and efficient device of this character, and consists in the features of con-
struction and combinations of parts hereinafter fully described and claimed.
The pure gold paint to which I especially refer, is such as made from gold
and is used for the decoration of the finer grades of ceramics.
The high intrinsic value and the physical and chemical nature of pure gold
paint are such as to present exacting conditions which must be fulfilled in
making such a package. On account of the great value of the paint, the recep-
tacle should make it possible to avoid the loss of even minute quantities,
through adhesion or penetration. And the materials of which the package
is made should not act chemically upon the paint. The receptacle should
exclude from the paint all foreign matter, such as dust and fuzz. and must
prevent evaporation of any of the constituents of the paint; for which reason
the receptacle must be hermetically sealed. Said receptacle should also reliably
withstand the extremes of various climatic conditions, and should permit ready
opening. It should also furnish a suitable surface upon which, after opening,
the paint may be finally manipulated and from which it may be at once trans-
ferred to the ware to which it is to be applied. Finally, to make the receptacle
commercially valuable, it must be capable of being cheaply manufactured and
transported. These conditions are all fulfilled by my improved package.
Heretofore, gold paints have been put on a glass plate and the plate enclosed
in a paste-board box. This method is objectionable because it permits the
evaporation of the volatile constituents of the oils or resins, embodied in the
paint, until finally the paint becomes so hard that it cannot be used. It has
been sought to obviate this by the addition, in manufacture, of materials which
will prevent drying. But this has proven unsatisfactory, one of the objections
being that the non-drying materials prevent the paint from drying after it has
been applied to the ware, so that it is difficult to handle without rubbing off
or smudging the paint wherever it is touched.
Placing the paint in an open manner upon a plate of glass exposes it to
particles of foreign matter, such as dust and fuzz, which, on account of the oily.
Such foreign
and sticky nature, of the paint, readily adhere to the matter.
matter causes imperfections in the finished work and often ruins the piece of
ware to which the paint is applied.
I have found through use, that in my improved receptacle, this paint will
keep fresh and clean indefinitely and without deterioration.

page_text: My improvement is illustrated in the accompanying, drawings, in which,
Fig. 1 is a transverse sectional view of a receptacle constructed in accordance
with my invention, taken on the line 1-1 of Fig. 2.
Fig. 2 is a top plan view of same.
Referring to said drawings,, A is the base of the receptacle. This is preferably
of glass or vitrified material. China which is glazed or vitrified will answer.
A base having the upper surface covered with a vitrified glaze or an enamel
will also answer. Said base should be plane or nearly so, as shown in the
drawing.
Bis the cover. This is arched or dished so as to be definitely out of contact
with the paint, and the edge C thereof is completely scaled or fastened to the
surface of the plate A, so as to form a hermetically sealed chamber between
the cover and the base.
I have used materials such as celluloid, collodium, gelatine, shellac, "metal"
and fibrous material. The latter was covered or impregnated with collodium,
gelatine, shellac, wax or varnish to make it air tight.
.I
The manner of fastening the cover to the base is empirical; it may be
fastened with any adhesive material that will hold it fast to the base and make
an air-tight seal.
:
I have also used a rubber, ring or washer and held the cover. fast, to the
base.
Said cover is preferably made of transparent celluloid, in order that the
gold paint may be inspected through the same by dealers and purchasers, and
in order that the cover may be more readily removed without bringing the tool
used in removing it, into contact with the paint. Celluloid or any material
not of a vitrified nature would not be a proper surface upon which to have the
gold paint rest. Chemical action injurious to the paint would result from
such contact. But it will be observed that there is no such contact in my package.
Celluloid has the advantage of being light, and it is possible to attach it to
the surface of the base, A, in a manner which is not deleterious to the paint
While it is light and thin and transparent, it is not fragile, and will not, become
shattered when jarred; and during removal it does not break into pieces and
deposit. particles into the paint. The cover may be removed by breaking the,
seal with,a suitable tool, of by cutting the body of the cover. The cover and
the base are, of such a nature as to be capable of being joined, to each other so
as to form a package adapted to a variety of temperatures and climatic condi
tions. This is an important fact which I ascertained through extended and
varied tests and experiments. In addition to meeting all other requirements,
the base and, the cover must be mutually.. adapted to each other, not only at
the time of manufacture, but also during the varying conditions of the future.n

to the glass or vitrified surface sufficiently for storage and transportation, and,
yet this surface permits ready removal of every particle, permits no. penetra-

nature, in order to protect them from exposure to particles of foreign matter
or evaporation of volatile constituents, and to prevent any loss of material by

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

1. As an article of manufacture, a package containing a preparation of a semi-
solid nature, said package consisting of a base of glass or vitrified material, a
semi-solid preparation adhering to one of the surfaces of said base; a 'cover-extend-

its edges hermetically sealed to said base, substantially as described and for
the purpose set forth.
2. As an article of manufacture, a package containing gold paint, said
package consisting of a base of glass, mass of semi-solid gold paint adhering
to one of the surfaces of said base, a cover extending over said mass of gold
paint out of contact with the latter and having its edges hermetically sealed to
said base, substantially as described and for the purpose set forth.
3. As an article of manufacture, a package containing gold paint, said package
