Improvements in the Packing or Putting up of Chloride of Lime
and other Substances.
I, Jons COCKBURN STEELE of J. C. Steele and Company, 16 Victoria Street,
Port Eglinton, Glasgow, in the County of Lanark, North Britain, Manufacturing
Chemists, 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 which relates to improvements in the packing or putting up of
Chloride of Lime, Carbonate of Ammonia, Pearl Ash, and other substances which give
off unpleasant odours, as well as substances which are volatile or liable to deliquesce
on exposure to the atmosphere consists as follows. The package is formed of thin
wood, paper, or cardboard of an oblong or other suitable form. A bottom is formed
on to one of the open ends of the package in any ordinary or convenient manner.
The other or open end of the package is provided with an extension of thin paper
or other ibin material, being secured to the inner edge of the mouth by any suitable
adhesive material, the said extension being for the purpose of enabling the material
to be shaken down and the package thus tightly packed.
The package before being filled is completely immersed in molten wax, and on
being taken out of the vessel containing the molten wax a thin layer thereof adheres
to the whole exterior and interior of the package, and on cooling down to the
temperature of the atmosphere the wax solidifies, so that all the joints are completely
closed, thus rendering the cardboard or other material of which the package is made
impervious to the escape of odours, and to moisture from the atmosphere. The
package after having thus been dipped and dried is filled with the substance such as
Chloride of Lime, or one of the others hereinhefore mentioned, and when filled the
paper extension around the mouth of the package is folded down and over the top of
the material, and then the cover, which has also previously been completely immersed
in wax, is fitted over the said end of the package; the inner sides of the said cap, or
the outer edge of the box itself having been previously coated with adhesive material,
so that the cap is completely sealed over the open end of the package.
In place of using wax alone, which may he animal, mineral or vegetable wax, as
the material for the dipping of the box and the cover as hereinbefore described, there.
may be mixed with such wax other substances such as rosin, pitch or gums, drying
oils or other suitable substances.
I do not limit myself to the employment of the said paper extension in the con-
struction of my said package, as the said extension may be altogether dispensed with
if desired, or may employ my equivalent of the said extension to effect the purposes
as hereinbefore described, but what I claim is.
The package, for containing Chloride of Line, or other substances, (and with or
without the mouth extended with thin paper or other material) made impervious to
air and moisture, substantially in the manner as hereinbefore described.
