ENVELOPE.

Application filed March 13, 1920. Serial No. 365,532.

To all whom it may concern:

Be it known that l, OHAnLns R. WILLIAMS, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Envelopes, of which the following is a specification.

My invention relates to improvements in envelopes, and the main object of my invention is the provision of an envelope which will possess a double seal, and thus prove of greater security and have more lasting qualities than the usual envelopes.

Another object of my invention is the provision of a double seal envelope which will perform all the functions of the ordinary envelope and which maybe used as a combined envelope and letter sheet if found desirable.

Another object of my invention is the provision of an envelope which will require little adhesive matter in its production;

which will be strong and durable; and

thoroughly efficient in every respect.

\Vith these objects in view my invention consists of an envelope embodying novel features of construction and arrangement of its parts as shown, described and claimed herein.

Figure l is a plan View of the complete blank or sheet from which the envelope is produced, looking at the inner face of the sheet.

Figure 2 is a plan View of the envelope with the parts in the position they assume when the four side flaps have been turned in or folded in forming the pocket of the envelope, and

Figure 3 is a central vertical sectional view of the completed envelope, the outer sealing flap being open or raised.

In producing my envelope a sheet or blank A is used which is scored at B, to form the main portion A and has at one end the guinmed outer sealing flap C, and at its other end the flap D, the gummed flap forming the outer sealing flap for the envelope, while the flap D, provides what may be termed the inner sealing flap.

lhe main portion A is formedwith the two pairs of lateral flaps E and E which are adapted to be folded inward to have their ends F overlap, and form the reinforcing portion G for protecting the pocket ii, formed by the adjacent overlapped flaps E, the reinforcing portion folding upon the pocket portion and in use the flap D folds in and seals the pocket, as seen in F igure 3, and the outer sealing flap C, closes the pocket with the inner seal. Thus an envelope is provided having a double seal, a series of thicknesses of material to make the envelope tough and strong, and one wherein the only adhesive necessary 1n the making of the envelope, is that which is used upon the outer sealing flap.

The envelope can be quickly and cheaply 7 made, can be used as a combined writing sheet and envelope, or only as an envelope, can be produced by an unskilled person and generally is a practical idea.

I claim:

An envelope formed from a single piece of material, said envelope comprising a rectangular body portion, spaced flaps extending outwardly from one side of said body portion, spaced flaps extending outwardly from the opposite side of the body portion and in alignment with the first mentioned fiaps,the flaps at the opposite sides "of the body portion being adapted to fold onto each other so that their endswill. overlap thereby forming pockets in combination with the body member-after the. body member has been folded on itself ona line in registration with the spaces between the flaps, an outwardly extending flap carried by one side of thebody member and dis posed between the flaps and at an angle thereto and adapted to be received inthe pocket formed at the opposite end of the body member, and a gummed securing flap for engaging over the outwardly extending flap and securing to the outer side of the body member adjacent the first mentioned flap.

In testimon whereof I afiix my signature.
