ENVIBLOP.

Application filed January 25, 1917. Serial N 0. 144,462.

To all whom it may concern:

Be it known that I, YOSHITADA YOSHINO, a subject of the Emperor of Japan, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Envelops, of which the following is a specification.

This invention relates to envelops, and more especially to a new and novel construction thereof, whereby a more sanitary cover or inclosure for letters and parcels is secured.

The objects of the invention are, to provide an envelop of pleasing and artistic design, to provide an envelop in which the blank form may be out with as'little waste of paper material as may be possible, to provide an envelop requiring a minimum amount of gummed surface in construction, to improve the means of sealing so that tampering with the envelop may be readily detected, and to construct the blank from which the envelop is made, so that the glue for securing the flaps in position may be applied only on one side thereof.

To this end the invention consists inthe peculiar construction of an envelop designed to open at the end for insertion of the letter or parcel, and designed with two flaps, one of which is gummed for a portion of its length to seal on one side of the envelop, and the other flap to fold upon the opposite side and be sealed by afiixing a postage stamp thereto.

The invention further consists in the arrangement, construction, and combination of parts.

Other objects and advantages will be apparent from the following detail description, and it will be understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invention.

In the drawings, Figure 1 is an elevation of the rear side of an envelop to which my invention has been applied. Fig. 2 is an elevation of the front or address side of the envelop. Fig. 3 is a plane view of the blank before folding to form the envelop. Fig. "I is a perspective of the envelop showing the flaps partly open for insertion of a letter or parcel.

Referring to the drawings, the envelop, in the preferred form of construction, consists of the front, or address side 5, from which extends the end flaps 6, 7 and the inner flap 8, and outer flap 9; said outer flap 9 having an extension 10, which, when the envelop is sealed, projects into a slot 11, cut in the front side of the envelop.

In constructing the envelop, the blank is first provided with gummed surfaces 12, 13, 14, the inner flap 8 then being folded upon the part 5, flaps 6, 7 then being folded in upon flap 8, and flap 7 being glued to flap 8. Flap 9 is then folded upon flaps 7, 8 and glued thereto.

The envelop thus formed, is then in commercial form, and ready for insertion of the letter or parcel. To close and seal the envelop, the end flap 6 is inserted beneath the outer flap 9, and, if desired, pasted to flap 8, although this is not necessary. The ungummed portion 15, of flap 6, is cut and formed to facilitate insertion beneath the outer flap. The extension 10 is then inserted in slot 11, located in the upper right corner of the envelop, and a postage stamp affixed thereto, completes the sealing of the envelop. The dotted lines in Fig. 2, indicate the sealed position of the postage stamp. The extension 10, is provided with perforations 16, to facilitate opening the envelop after the postage stamp has been affixed thereto. The envelop shown in Fig. 1 is constructed without such perforations.

It will be noted that the construction and manner of sealing the envelop as herein described, is such as to make practically impossible the removal of contents without detection. Its simplicity will commend the use of the envelop for business and. private correspondence. The envelop is efficiently sealed by afiixing the postage stamp thereto. The envelop is more sanitary than those of prior construction, as only the gummed surface of the stamp need be moistened. To,

open the envelop after sealing, -the postage stamp or the extension flap to which it is glued, must be mutilated, and it cannot again be sealed after cancellation of the stamp, without detection.

WVhat is claimed is:

An envelop cut from a substantially rectangular blank, comprising a front part, an inner flap, folded upon said front part, an end flap folding upon and glued to said inner fiap, an outer flap folding upon the inner flap and glued thereto for a portion of its length, an end flap to be inserted beneath Specification of Letters Patent.
