Improvements in Envelopes.
I, JOHN JOSEPH LUSSIER, resident of 245 Broadway, New York, County of
New York, and State of New York, United States of America, Roundsman, 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
Specification:-
This invention relates to envelopes and to the manufacture thereof; and the object
of the invention is to provide an envelope which having been once sealed, cannot be
opened without destroying the envelope or leaving evidence of the act.
The invention is fully disclosed in the following Specification, of which the
accompanying drawing forms a part, in which:
Fig. 1 is a view of an envelope made according to my invention, and ready for
sealing; and
Fig. 2 is a view of the same sealed.
In the practice of my invention, I cut from a suitable sheet of paper, of any
desired color, or quality, a blank comprising a body portion A, folding ends B, and
a folding side D and a flap G.
The side D, is provided with a slot d, and the flap G with a tongue g, and the
inner surface of said tongue is gummed as shown at g', and the inner surfaces of the
sides of the flap G, are also gummed as shown at g¹.
In practice, the inner surface of the sides of the flap G are also gummed, and
in preparing the envelope for use, the ends B are folded over in the usual manner,
and the side D, is then folded over and sealed to said ends; and when it is
desired to seal or close the envelope, the flap G is folded over the ends of the
side D, and the tongue g is opened backwardly and sealed to the inner surface of
the ends and the side D, is shown in dotted lines, in Fig. 2.
It will be understood, of course, that the gummed surfaces of the flap G, and
the tongue g are moistened before the latter is inserted through the slot d, after
which these parts are pressed together in the usual manner; and when constructed
and sealed in the manner described, the envelope cannot be opened without
tearing off the tongue g, as moisture cannot reach the inner surface thereof, and
it will thus be seen that I accomplish the object of my invention, by means of
a simple and effective construction which does not add materially to the cost of
the envelope.
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. An envelope composed of a body portion, folding end portions, and a folding
side, together with a folding flap, said side being provided with a slot, and said flap
with a tongue, which is gummed on its inner surface, and adapted to be inserted
through said slot and sealed to the inner surfaces of the ends and of the side,
substantially as shown and described.
2. An envelope composed of a body portion, folding end portions, and a folding
side, together with a folding flap, said side being provided with a slot, and said flap
with a tongue, which is gummed on its inner surface, and adapted to be inserted

page_text: through said slot, and sealed to the inner surfaces of said flap and of said side being
also gummed, substantially as shown and described.
