LEOPOLD GROS, of Albany Street, in the County of Middlesex, Commission
Agent. "IMPROVEMENTS IN CAPSULES FOR BOTTLES, JARS, AND OTHER VESSELS
OF CAPACITY, AND IN THE MANUFACTURE OF THE SAME."
My Invention relates to improvements in capsules for bottles, jars, and other
vessels of capacity, and in the manufacture of the same, and according to my first
method of manufacture, the capsule consists of two parts or pieces, viz., a tubular
or cylindrical portion which surrounds the neck or mouth of the vessel, and a disc
which forms the top or closing piece of the tubular or cylindrical portion. These
two portions when united together form the improved capsule.
I purpose to manufacture the tubular portion of my improved capsule from
blanks of paper of great strength and tenacity, as such are best calculated for the
purposes of my Invention, and the discs of straw-board, pasteboard, millboard,
wood, or other suitably rigid material.
The blanks, from which the tubular or cylindrical portion of these capsules is
formed, are cut or punched out of a sheet or sheets of the paper aforesaid to the
form of a segment of a circle or other suitable form, as required, and have their
lower edge or border provided with a number of slits, scollops, or indentations.
The purpose of these slits, scollops, or indentations, is to cause the capsule to lay
close on the vsssel, and to avoid wrinkles or folds therein.
The blanks thus cut to the required shape are folded into their tubular or
cylindrical form, and their lateral edges are united by cement or like adhesive
material. They are now ready to receive their discs, but previous to uniting their
lateral edges their lower edges may be gummed inwardly for the purpose herein-
after mentioned.
The discs after being cut or punched out to the required size and shape, are inserted
and fitted into the tubular or cylindrical portions by hand or by any suitable
machine, and are retained therein by cement or other adhesive medium.
The portions of the capsule between the slits, scollops, or indentations, as well as
the portion above, such slits, scollops, or indentations of the tubular or cylindrical
portion of the capsule, may be perforated in order that when the capsule has been

without its complete destruction, thus rendering it valueless, and thereby
preventing the contents of the vessel being tampered with, as is now often the case
with existing capsules, which can be removed with facility, and after the contents
have been abstracted or tampered with the capsule can be easily replaced.
The capsules may be varnished or they may be coated with liquid glass, or
silicate solution, or with other suitable solution in order to render them waterproof
and air tight, the varnish or coating being applied either inwardly or outwardly,
or both inwardly and outwardly.
The capsule thus manufactured is applied to the vessel in the usual manner, and
is affixed thereon by hand or by any suitable capsuling machine, the gummed and
scolloped and perforated portions of the capsule (or the neck or mouth of the
vessel) being previously damped or moistened in order to cause adherence of the
capsule.
According to my second method I manufacture capsules from paper pulp,
combining therewith size or other gelatinous or glutinous body, to cause the
particles of the pulp to adhere together. I then introduce the pulp into suitably
.constructed moulds, into which plungers enter and force the pulp into the required
form. The capsules on being removed from the moulds are set aside to dry, or are
dried; they can then be perforated and varnished or coated with the desired
solution.
