POCKET ENVELOPE Patented Aug. 1, 1944 UNITED STATES PATENTTOFFICE Frank L. McCarty, New Bedford, Mass.

Application June 29, 1942, Serial No. 448,967

1 Claim.

The present invention relates to new and useful improvements in envelopes designed primarily for use in containing photographic printing paper.

It is a common practice, when purchasing a package of photographic print paper, to take one sheet of the paper and cut it into test strips. If the strips are replaced in the envelope containing the paper, there is danger of damaging the full size sheets therein by chemicals deposited on the hands from photographic solution.

Accordingly, it is an object of the present invention to provide an envelope having a pocket therein for the storage of such test strips, thereby eliminating the danger of damage to the print paper by returning the test strips to the main pocket of the envelope.

A further object is to provide an article of this character of simple and practical construction, which is eflicient in use, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which Figure 1 is a perspective view illustrating one embodiment of the invention.

Figure 2 is a vertical sectional view taken substantially on a line 2-2 of Figure 1.

Figure 3 is a plan view of the blank from which the envelope is formed.

Figure 4 is a perspective View of a modified construction.

Figure 5 is a sectional view taken substantially on a line 5--5 of Figure 4.

Figure 6 is a plan view of the blank from which the envelope, illustrated in Figure 4, is constructed.

Figure 7 is a perspective view of a further modification, and

Figure 8 is a plan view of the blank forming the last-named envelope.

Referring now to the drawing in detail, and with particular reference to Figures 1 to 3, inclusive, the numeral 5 designates the envelope blank constructed of suitable paper for containing photographic print paper, the blank including a body portion 6, an upper flap 1 connected to the body along a fold line 8, a lower flap 9 connected to the body along a fold line ID, the lower flap being coated with an adhesive II on its inner surface. To one side of the body 6 is connected a strap l2 by means of a fold line l3 and at a relatively opposite side of the body is a flap designated generally at l4 connected to the body by a fold line l5, the flap I4 including an inner flap section l6 and an outer flap section I! separated by means of a vertically extending strip of adhetive l8 on the inner side of the flap, the flap section I! being of reduced height and is also provided at its outer edge with a strip of adhesive IS on its inner surface.

In constructing the envelope the flap I2 is turned inwardly along the fold line l3 and the flap I4 is then also turned inwardly along the fold line l5 and the adhesive strips 18 and I9 moistened for adhering to the flap l2, after which the flap 9 is folded upwardly and secured by the adhesive H to the outer surfaces of the flaps l2 and I4, whereby to form the main pocket 20 and the auxiliary pocket 2|. The main pocket 20 is adapted to contain the print paper and the auxiliary pocket 2| being positioned outwardly of the flap I2 of a smaller size and adapted to contain the test strips cut from a sheet of the print paper. The top flap T is adapted to close the opening of both of the pockets 20 and 2|.

In the form of the invention illustrated in Figures 4 to 6, inclusive, the side flap 22 is substantially coextensive with the body 23 of the envelope blank and is adapted to fold thereon to form the main pocket 24, while the other side flap 25 is of a smaller area than the flap 22 and is provided with the adhesive strip 26 for securing to the flap 22 when the flap 25 is folded upon the former. The reduced flap 25 is provided with an inclined upper edge 21 which forms the opening for the auxiliary pocket 28 and into which the test strips may be inserted.

In Figures 7 and 8 of the drawings, the side flap 29 is shown constructed of a width slightly less than the body 30, while the other side flap 3| is constructed of a width substantially coextensive with the width of the body 30, and is also formed with the intermediate and outer strips of adhesive 32 and 33 for engaging the outer surface of the flap 29 when the latter is folded inwardly upon the body of the envelope.

The flaps 29 and 3| cooperate to form the main pocket 34 and the outer section of the flap 3| forms the auxiliary pocket 35.

It is believed the details of construction and manner of use of the device will be readily understood from the foregoing without further detailed explanation.

Having thus described the invention what I claim is:

An envelope comprising a blank sheet of paper including a body portion, flaps at the upper and lower edges thereof, said lower flap being gummed, and flaps at the Side edges of the body adapted for'folding inwardly upon each other against the body, one of said side flaps being of a height equal to that of the body and of a width less than the width of the body, and said side flaps being arranged in overlapping relation and with said one flap. disposed behind and cooperating with the other-side flap to 'form a main pocket with the body, the other of said side flaps having a portion the same height as that of the
