"IMPROVEMENTS IN CAPSULES FOR BOTTLES, JARS, AND OTHER VESSELS OF
CAPACITY, AND IN THE MANUFACTURE OF THE SAME."
My improved capsules for bottles, jars, and other vessels of capacity consists of
two parts or pieces, which when united together form the complete capsule. These
parts or pieces consist 1st., of a tubular or cylindrical portion, which surrounds
the neck or mouth of the vessel; and, 2ndly, of a cap, head, or closing piece
forming the top of such tubular or cylindrical portion.
I manufacture these capsules from blanks of paper of great strength and tenacity,
as such is best calculated for the purposes of my Invention.
These blanks from which the tubular or cylindrical portion of the capsule is
formed are cut or punched out of a sheet or sheets of such paper to the form of a
segment of a circle or other suitable shape, as required, and are provided with a
number of slits or divisions around their lower edge, and the cap head or closing
piece is cut or punched to the form of a circle or other suitable shape, and is pro-
vided with a number of radial slits or divisions formed around its circumference, so
as to cause it to fit closely and neatly into the tubular or cylindrical portion when
placed and secured therein by adhesive material.
An essential feature of iny Invention consists in perforating the lower portion of
the capsule and in applying an adhesive agent to the inner surface thereof, in order
that when such capsule is applied to the vessel and affixed thereto it cannot be
removed without its complete destruction, thus rendering it valueless. By theso
means the contents of the vessel are protected from fraud; as with existing capsules
they can be removed with facility from the vessel, and the contents thereof, after
being tampered with, the capsule can be replaced.
The edge or edges of the tubular or cylindrical portion of the capsule, as well as
the circumference of the circular portion, may be perforated, so as to allow the
adhesive material to penetrate and cause thein to adhere firmly together when
joined.
The two pieces or parts so prepared are then put together, and thus constitute
the capsule, and the slit portions of the cap or head having been previously turned
down and gummed (or the interior of the tubular portion guinned), these pieces
when put together adhere firmly to each other.

page_text: The capsules can be varnished or otherwise treated so as to render them
waterproof and air-tight.
Prior to making up and uniting the blanks to form the capsule they may be
printed or embossed with the name of the manufacturer or seller of the goods
contained in the vessels to which they are to be applied.
The capsule thus prepared is then applied to the neck or mouth of the vessel in
the usual manner, and is affixed thereto by any suitable capsuling machine, the
gummed and lower perforated portion being previously damped to cause the
adherence of the capsule to the vessel; or the neck or mouth of the vessel may be
damped or moistened.
