ENVELOP.

Continuation of application Serial No. 403,711, filed November 25, 1907.

Serial No. 468,569.

Specification of Letters Patent.

Patented. July 2, 1912. This application filed December To all whom it may concern:

Be it known that I, GEORGE J. HARTKE, a

citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Envelops, of which the following is a specification. The present invention relates to an envelop of the class shown and described in Letters Patent No. 532,206 grant-ed January 8th, 1895, to A. D. Klaber which is known to the trade by the name Neostyle.

The Neostyle envelop as shown in the patent and as heretofore made is open to several objections. One of these is that during the filling operation the loose side flap is held in place only by reason of the fact that it projects a short distance beneath, or, to state it differently, is partly overlapped by the adjacent side of the bottom flap but otherwise it is not engaged by any part of the envelop that would have a tendency to hold it in place. Being loose and disengaged, except as aforesaid, when the envelop is being filled, it is sometimes forced upward and outward and freedfrom engagement with the bottom flap. This is apt to happen frequently unless the operator is experienced. Another objection to the Neostyle envelop as heretofore made is that even after it is filled and sealed, the loose flap is sometimes freed from its engagement with the top and bottom flaps and forced out. This may happen when pressure is suddenly exerted upon the sealed envelop, especially when several of them are piled up, one upon another, immediately after being sealed. When first sealed a considerable volume of air is imprisoned in the envelop and the sudden expulsion of this air incident to compressing the pile of envelops, blows the loose flap out. Again the loose flap is sometimes forced out as the mail is being distributed or otherwise handled. This will happen if the envelop with its inclosure is so handled that the inclosure is thrown against the loose flap,

' especially if the inclosure is heavy.

The object of the present invention is to provide an envelop which has all the advantages of the Neostyle and which, at the same time shall be free from the object-ions above pointed out.

To this end the invention consists in the features of novelty that are hereinafter described.

In the accompanying drawing which is made a part of this specification, Figure 1 is a diagrammatic representation of an envelop partly folded, embodying the invention. For the purposes of this application this is elected as the preferred form of the invention. Figs. 2 and 3 are similar views showing modifications.

In all of the figures of the drawing similar parts are indicated by similar reference letters.

A represents the front of the envelop, B the top or sealing flap, C the bottom flap, D the loose side flap and E the remaining side flap, the flaps C and E being fixedly secured together as hereinafter described. The drawing shows the side flaps folded to the positions which they occupy in the completed envelop, and shows the top and bottom flaps as they appear in the blank, the positions which they occupy in the completed envelop, after the blank is folded on the dotted lines a and a, being indicated by the dot-ted lines 6 and 0, respectively.

In folding the envelop, the side flap E, is first folded down upon the front A. The loose side flap D is then folded down upon the front, and also upon the side flap E to the extent of a portion d which overlaps it. The bottom flap C is then folded down upon the front A and also upon both of the side flaps. The adjacent sides of the bottom flap and the loose side flap overlap each other but they are not united in any way. The bottom flap G is then folded down upon the front A and also upon both of the side flaps. A portion of the bottom flap overlaps and lies upon the outside of a portion of the loose side flap but they are not united in any way. A portion of the bottom fiap C also overlaps and lies upon the outside of a portion of the side flap E, and limited areas of the surfaces of their overlapping portions are fixedly united or secured together by any suitable adhesive substance as shown by the shade lines F, thus leaving other limited areas of the surfaces of the overlapping portions ununited forming a pocket as shown at f. This adhesive substance may be applied to either or both of the said flaps, C and E, indiflt'erently. The shade lines on the several flaps arenotinof the fixed bottom and side flaps and adapted to engage the bottom side of the stop.

3. An envelop having a front, a bottom flap and a side flap, said side flap being overlapped by the bottom flap, means for fixedly uniting limited surface areas of the overlapping portions of said flaps, thereby forming a stop, and leaving limited surface areas of said overlapping portions ununited, thereby forming a pocket adjacent to said stop, and a loose side flap opposite the fixed side flap aforesaid, said loose flap being overlapped by the fixed bottom flap and having a portion lying between the ununited portions of said overlapping portions of the fixed bottom and side flaps, that portion of the loose fiap which lies between said ununited port-ions of the fixed bottom and side flaps having an angularly disposed shoulder presented toward the rear side of the stop.

t. An envelop having a front, a bottom fiap and a side flap, the side flap being overlapped by the bottom flap, means for fixedly uniting limited surface areas of said overlapping portions, thereby forming a stop, and leaving limited surface areas of said overlapping portions below said stop ununited, thereby forming a pocket below the stop, and a loose side flap opposite the fixed side flap aforesaid, said loose side flap being overlapped by the fixed bottom flap and having a portion lying between the ununited portions of the overlapping portions of the fixed bottom and side flaps and adapted to engage the bottom of the stop, that portion of the loose flap which lies between the ununited portions of the overlapping portions of the fixed bottom and side flaps having on its top side an angularly disposed shoulder presented toward the rear side of the stop.

5. An envelop having a front, a side flap, a bottom flap overlapping the side flap, means for fixedly uniting limited surface areas of said overlapping portions, thereby forming a stop, and leaving limited surface areas of said overlapping portions ununited, a loose side flap overlapped by the fixed bottom flap and having a portion lying between the ununited portions of said overlapping portions of the fixed bottom and side flaps, a fourth or sealing flap overlapping the fixed bottom and side flaps and also the loose flap, and an adhesive substance for uniting the sealing flap to at least one of the fixed flaps.

6. An envelop having a plurality of flaps and a stop, one of said flaps being loose and provided with a portion lying between ununited overlapping portions of two of the other flaps, and another of said flaps being a closing or a sealing flap which overlaps all of the other flaps, on the outside thereof, and an adhesive substance for uniting. said sealing flap with at least one of the fixed flaps, leaving the loose flap free to be with drawn.

7. An envelop comprising a plurality of flaps, sealing means for securing one of said flaps to another along one edge, an interruption in said sealing means, and a flap having an angularly disposed tongue adapted to project through the sealed edge at said interruption.

8. An envelop comprising a plurality of flaps, means for securing said flaps along one side, said flaps being unsecured along the other side, an interruption in said securing means, and a loose flap having an angular end adapted to project through the securing means of said interrupted portion.

9. An envelop comprising a plurality of flaps, means for securing said flaps together at their edges, an interruption in said securing means, a loose flap having its edges covered by the secured flaps when in closed position, said loose flap having an end passing between and projecting beyond said flaps at said interruption.
