JOHN GEO. KNURCK, OF WOODHAVEIN, NEW YORK.

ENVELOP OB WRAPPER.

Application filed July 17, 1915.

To all whom it may concern:

Be it known that I, JOHN GEORGE KNURGK, a citizen of the United States of America, residing at WVoodhaven, in the county of Queens andState of New York, have invented certain new and useful Improvements in Envelops or \Vrappers, of which the following is a specification.

My invention relates to envelops or wrappers and particularly to that class of coverings which are used to inclose articles which may be delivered by mail at other than first class rates, and it consists in providing for a closure of one end, in such manner that though it may be readily opened for inspection, it will nevertheless be normally entirely closed and will securely retain the contents within.

Figure 1 is a plan view of a form of blank embodying my invention. Fig. 2 is a similar view of the envelop formed from the blank of Fig. 1, when partially folded into envelop form. Fig. 3 is a similar view of said envelop, when one flap has been folded in. Fig. 4 is a similar view of the said envelop, when entirely closed. Fig. 5 is a longitudinal sectional view of the envelop of Fig. 4. Fig. 6 is a perspective view of said envelop when one flap has been pulled out and the parts spread open at the end, to expose a part of the other flap. Fig. 7 is a perspective view of said envelop, when the unsealed end is spread open to exhibit the positions of the flaps.

Any size or shape of envelop may be adopted as the form to be exhibited when the article is complete and is closed as intended. In the one exhibitedfor purposes of illustration, I have used a blank which will form a rectangular envelop from a single piece of paper, folded so as to overlap and sealed at one end and along the longitudinal line where one wing folds over the other. In this embodiment, 1 is the body part which will form one side or face of the completed article, 2 and 3 are wings which are to be folded over on the dotted lines and secured by paste along the overlapping longitudinal edges to form the other side, or back, of the completed article, 4 is the end flap which is intended to be folded over the ends of the

wings

2, 3, on line 5, and to be secured to said wings by paste, 6 is one flap and 7, 8, the other flap which, together, are -to produce my particular closure and 9 and 10 are lines on which I pre- Specification of Letters Patent.

edge of flap 4, but to leave it unsealed until the article to be inclosed in the envelop has been placed therein, and to complete the closure by sealing down that flap 4, since it is easier to insert an article at that end and seal it by moistening the gum and pressing that flap down than it would be to insert the article at the other end and then turn in the flaps which make my particular joint, but the order of procedure is immaterial and, if found desirable, the flap 4 may be folded down on line 5 and sealed in the course of manufacture. It is the closing at the other end that is of particular importance. That is accomplished by providing the two tabs, already described, one projecting from the face of the envelop and the other from its back, one being longer than the other, preferably nearly twice as long, then creasing them, usually in course of manufacture, on line 9 and line 10, the line 9 being one which defines the end of the closed article. as plainly shown in Fig. 4, then folding tab 8 over outwardly, preferably on line is and then inwardly on line 9 and passing the thus doubled tab in between the face and the back of the envelop, where it will appear as a V shaped trough, as shown in dotted lines in Fig. 3 and in partly dotted and partly full lines in Fig. 6. Then the tab 6 is folded in on line 9 and passed into the V shaped space between

parts

7 and 8 of the long flap, as shown, in section, in Fig. 5. If creased and folded smoothly, the parts will then lie flat, but the end will be effectually closed, since a pamphlet or similar article, within, will be restrained from escape at the fold between 1 and 7 on one side or facesee Fig. 5-or at the fold between 3 and 6, at the other side or face, and

the edge of flap 6 will be held between

parts

7 and 8. Examination of Fig. 5 will show the necessity for making

flap

7, 8, longer than flap 6, since it must reach inward from the common fold line 9 to a line as far removed from the line 9 as is the extreme edge of tab 6 from that line and then back again for at least some distance, in order to fold back over said free edge of said prefer to proportion the parts so that the reversely folded part 8 shall reach almost back to-the fold line 9, since the longer it is (provided it does not exceed the length of flap 6), the more secure. the joint will be. If, by mistake, either flap should be made too long, itvcan still be used by folding down the extra width so as to make the resulting flap of the required length, even though it would .be,'in some part, of double thlckness.

What I claim and desire to secure by Letters-Patent, is z 1. An envelop provided at its open end with two flaps,

extending respectively from the face and back beyond the body portion of the envelop, one of said flaps being longer than the other, bled upon itself into the opening along the edge of said longer flap being douand adapted to be inserted of the envelop by folding the body portion, and the shorter flap adapted to be folded along the edge of the body portion, and inserted between the doubled sides of the longer flap. An envelop provided at its open end with two flaps, extending respectively from the face and back beyond the body portion of the envelop, one of said flaps being longer than the other, said longer flap being doubled upon itself on a line of fold beyond the free edge of the shorter flap, and adapted to be inserted into the opening of the envelop by folding along the edge of the body portion, and the shorter flap adapted to be folded along the edge of the body portion, and inserted between the doubled sides of the longer flap.

In testimony whereof, I have signed my name to this specification this 16 day of July, 1915.
