1 Claim.

This invention relates to an envelope and blank therefor, the envelope being of the open side type without a flap particularly adapted for the reception of sales checks.

The improved envelope is advantageous both to the manufacturer and user. Heretofore to produce open side envelopes it has been customary to produce an envelope of the usual size having a flap, the flap being later cut off from the finished envelope with consequent waste of material. The reason for the provision of the flap has been the fact that the envelopes are preferably made upon a rotary envelope machine such as illustrated in the patent to Novick, Number 1,121,125, December 15, 1914. In this machine there are provided aligning and guide pins to properly position an envelope. For these pins to act, it is necessary that they engage reentrant corners. The primary purpose of providing flaps, therefore, on open side envelopes has been to provide reentrant corners for engagement by the pins.

The improved envelope is also very advantageous to the user inasmuch as it affords two features permitting not only ready opening of the envelope for the reception of a sales slip, or the like, but also an arrangement which permits its ready insertion into the diagonal leather corners of a sales book cover.

The broad object of the invention is the provision of an economical open side envelope without a flap, the edges of the walls being even. In order to produce this commercially, it must be run on a machine, a practice which requires the provision of reentrant corners.

Other objects of the invention relating to the accomplishment of the above features and other advantageous points will be apparent from the following description read in conjunction with the accompanying drawing in which:

Fig. 1 is a rear elevation of the improved envelope; and

Fig. 2 is a plan view of the blank from which theenvelope is formed, certain portions of the machine being illustrated in construction lines.

The blank which comprises. a single sheet of suitable paper provides a front wall 2 and a back wall 4, these two Walls being adapted to be folded relatively to each other about the fold line 5. Side flaps 6 carried by the front wall are arranged to be folded thereon on the fold lines 7. These side flaps 6 preferably extend from the fold line 5 to a position short of the outer edge 12 of the front wall so as to provide a reentrant corner 8 between the upper end of each flap and the corresponding side of the front wall.

In the formation of the envelope the flaps 6 are folded upon the lines '7 on the inside of front wall 2. The rear wall 4 is then folded thereover and secured to the flaps by suitable adhesive in the fashion usually carried out by an automatic envelope machine. It will be noted that the side edges 10 of the back wall are cut inwardly from the fold line 5 so that at the open side of the envelope the front wall projects sidewise beyond the back wall as indicated in Fig. l. The free edges 12 and 14 of the front and back walls are equidistant from the fold line 5 so that they lie in alignment in the finished envelope as indicated in Fig. 1.

The advantages of the blank will be clear from a consideration of certain parts of the machine illustrated in construction lines in Fig. 2, name- 1y, conveyor belts l8 and guide pins 20. These guide pins by reason of the formation of the blank may properly act to align the blank by engagement within the reentrant corners indicated at 8. Reference to the Novick patent, mentioned above, will make clear the operation of these pins.

1n the use of the envelope the projection of the front wall beyond the rear wall serves a very useful purpose inasmuch as the thumb of the user by engagement with the projecting portion of the front wall effects ready opening of the open side of the envelope for the reception of papers. Without this arrangement it is frequently quite difficult to attain opening of the envelope.

Besides this advantage there is the second advantage in that the single thickness of the front wall at the corners permits a more ready insertion of the envelope into the diagonal corners of a sales book cover, it being remembered that the front of the envelope in that case extends outwardly. Accordingly the single thickness enters the corner first while the rear wall sliding over the cover itself readily follows the corner of the front wallbeneath the diagonal corner.

What I claim and desire to protect by Letters Patent is:

An envelope comprising a one-piece blank providing front and back walls and side flaps, said front and back Walls being defined from each other by a fold line, the front and. back Walls having free edges equidistant from the fold line whereby in the finished envelope they lie together, the side flaps being carried by one of said walls at its sides, the lines of junction with the wall terminating substantially short of the free edges of the walls, the side flaps being secured to the wall which does not carry them, the last named wall being narrower at its free edge than the other whereby corners of single wall thickness are provided.

EDWARD G. MOORE.
