COMPLETE SPECIFICATION,
. Improvements in Envelopes and in Means for Opening same.
I, JOHN HENRY STEWART, of Lea Bank, 45, Rectory Road, Crumpsall, Near
Manchester, Consulting Engineer, 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 for improvements in envelopes and in means for opening same
has for its object an improved construction whereby letters or the like can be
readily inserted in the envelope and the envelope sealed and also relates to a
simple device to be fitted to the envelope whereby it can be opened without
risk of tearing or damaging the contents, and consists essentially in forming the
envelope in the shape of a bag open at one end or side and provided with a narrow
gummed flap which can be fastened down to close the envelope and in securing
to one portion of the envelope a piece of thread or other suitable material which
when pulled outwards will sever the envelope and admit of easy withdrawal of the
contents.
In order to more clearly describe this invention reference is had to the
accompanying sheet of illustrative drawings in which,
Fig. 1 shows an envelope in accordance with this invention, one portion being
turned back to show the construction.
Fig. 2 shows the blank for making the envelopes and Fig. 3 is a perspective
view showing the envelope ready for use.
The blank from which the envelope is made is formed as shown in Fig. 2 with
the face and back portions ab side flaps cd and end flaps ef. Creases are formed
on the lines ghij.
Within the crease ja piece of thread or other suitable material k is fitted secured
by gum or other adhesive and the ends project slightly at one or both ends.
The flaps ed do not extend quite up to the crease ; to allow for the folding over
of the flap c.
In making up the envelope (see Figs. 1 and 3) the side flaps ed are turned
in on the creases hi and the face portion a turned upon the crease g on to side
flaps cd which are coated with adhesive so that the face portions will adhere there-
to the result being an envelope of bag shape closed at the bottom and at the sides
and open at the top. The end flaps e fitted with the thread k in the crease j is
then turned down.
A letter or other article for transmission can be readily inserted into the
envelope and then by moistening the flap e, and putting the flap f which is coated
with gum or other adhesive against flap e it will thoroughly enclose the contents,
and leave a smooth surface on both sides of the envelope. By this arrangement
licking of gum to fasten is dispensed with.
In order to open the envelope one end of the thread is pulled outwardly and the
flap e will be severed along the crease j thus allowing of the contents being
withdrawn without risk of tearing or damage thereto.

page_text: 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
I claim is:-
(1) Improvements in envelopes consisting in forming the envelope in the shape
of a bag open at one end or side and provided with a narrow gummed flap which
can be fastened down to close the envelope and in securing to one portion of the
envelope a piece of thread or the like which when pulled outwards will sever the
envelope and admit of easy withdrawal of the contents substantially as described.
(2) An improved envelope comprising face and back portions ab secured
together by means of side flaps c d to form a bag closed on three sides, flap e turned
down on the crease j, flap ƒ coated with gum or adhesive and adapted for closing
the envelope, and thread k secured in the crease j for severing the flap e and
opening the envelope substantially as described.
(3) An improved envelope comprising face and back portions ab side flaps ed
and flaps ef creases g h i j and thread arranged in crease substantially as described
with reference to the drawings and for the purposes specified.
