Patented Nov. 5, 1929 UNITED STATES PATENT OFFICE GEORGE C. SNYDER, OF NEW YORK, N. Y., ASSIGNOR TO KAELMA MANUFACTURING m: COMPANY, INC., OF NEW, YORK, N. Y., A CORPORATION OF NEW YORK BAG OR ENVELOPE Application filed November 28, 1924. Serial No. 752,667.

This invention relates to handled bags or envelopes of the general type shown and described in my prior application, filed October 17, 1923, Serial No. 668,992. a

One of the objects of the present invention is to provide a bag or envelope which has a handle, that is operable on the closure flap of the bag and is adapted to be extended or moved through the wall which sup ports the flap in order to close the flap, with means for automatically and mutually looking or binding the handle with the two walls of the bag when the flap is closed, the locking or binding action being preferably of such nature as to create a resistance which is just sufficient to hold the mouth of the bag closed against any tendency of the contents of the bag to open its mouth when the bag is overfilled.

Another object is to so simplify and construct the handle that when the flap of the bag is closed, a positive outward pull on the flap will retract the handle and automatically overcome the looking or binding action,

so that the flap of the bag may be opened with ease, thus avoiding the necessity of any other manipulation than a mere positive pull on the said flap, and therefore locking and unlocking the bag may be repeated. 7

With these and other objects in view, the invention consists of certain features of construction and combinations of parts to be hereinafter described and then claimed with reference to the accompanying drawings illustrating several embodiments of the in ,vention, and inwhich Fig. 1 is an elevation'of a bag with the closure flap open, and showing one embodiment of the invention; v I

Fig. 2 is a section on the line IIII, Fig. 1;

Fig. 3 is an elevation of the bag showing the closure flap closed and the handle extending above the fold-line of the flap, and also showing how theinterlock between the handle and the two walls of the bag is established.

Fig. 4 is a section on the line IV-IV, Fig. 3; j Figs; 5 and 6 are enlarged detail Views, respectively in section and sectional plan, on

line VIVI, Fig. 5 showing how the handle is releasable; a

Fig. 7 is an elevation of a modified handle;

Fig. 8 is a transverse section on the line VIIIVIII, Fig. 7; I

Fig. 9 is an elevation of another modified form of handle; and a Fig. 10 is a transverse section on the line XX, Fig. 9.

Referring to Figs. 1 and 2, the bag or envelope has walls 10, 11, and a closure fiap 12 which is foldable at fold-line 13. A handle 14 has at one end an attaching member 15 which is preferably secured at the outer part thereof to the inner surface of the outer end rial, such as paper-board for example.

The ends of the attaching member 15 are adapted to form shoulders at 15 towards the handle proper, and adjacent to said shoulders the base of the handle is somewhat wider than the handle itself so as to provide lateral base portions 17 for a purpose to be mentioned. The handle has shoulders or small projecting portions 18 which roject away from the plane of the handle and arelocated at its base, on the other side of a straight transverse line which is coincident with the edges of the shoulders 15. These shoulders 18 are preferably of approximate V-form, with the apices pointed towards the terminal of the handle and with their substantial squared shoulders-proper 18 at the of forming the handle, so that when one surface of the handle is attached to the flap oi the envelope the shoulders 18 will project slightly away from the other surface of he handle.

The terminal 19 of the hanthe 14- s pr terably located in a transverse slit 20 in the wall 11 so as to norma slightly through said slit for en a persons lingers; The back wal bag is provided with a cut-out 21 V c having square corners and parallel eas s 2L at each end. It will be noticed tha 20 is of approximate y the same length the cut-out 21 and that it is practically coincident with the longjtransyerso ed 'e of the cut-out, for the purpose of obtaini preferably desired, the closest loc.-.. operationbetween the handle and the two Walls of the bag when the flap is closed.

Referring to Figs. 3 and i, the bag is shown as closed, that is to say, it has been closed by' a person who preferably takeshold of the terminal 19 of the handle. or flap closing means, and pulls thereon away from the bag and outwardly away from the tol inel of the flap, so that thehandle willextend away from the bag'when the flap is closed.

It will more clearly be observed from the section. Fig. 4 ust how the interlock or binding action is'established between the handle and the two walls of the bag. Y'Vhen the flap is being pulled shut; the wider. base portion of the handle. at 17. will be pulled snug into the slit 20 and said slit practically. sealed closed. and the shoulders 15 onthe handle which are preferably free of adhesive and are not themselves directly secured. to the flap. will be brought into binding relation with the portions 22 of the back wall'lO. atone side of theslit 20; while the shoulders 18 willbe pulled through the'slit and the': shoulder; proper 18, will establish;an interlock, at the other side of the slit. between the front wall 11 and theprotruding handle. This tion results in av mutual'interlock'or hind" action betweenthe two walls of the bag'and he handle, the binding action takin place opposite sides of the slit 20 or in other words at the opposite side walls 0t bagover which the flap is closed. This binding ac tion preferably takes place in the vicinn of the extreme ends of the slit. llhen the shoulders-proper. 18, are at tie approii mate angle as shown they will be given a snugger and better binding; contact with the lower edge of slit 18, as is'obvio ;s.

It is preferable to apply a reinfercins patch 23 to'the slitted wallof the so a to strengthen the bag thatiportion.

It will be clear to those skilled in the art that as the preferred material of the bag or envelope is thin paper such bags of this general type are usually composed. the bag is so thinthat the sectional views are somewhat exaggerated. That is to say, in practice the portions of the wall 10, 11 which are located at opposite sides of the slit 20 and the portions of the patch 23, as well as other involved portions of the bag, lie substantially in the planes which such parts assume in a thin flat bag;

It the bag or envelope is over-tilled. a considerable bulging thereof is produced with a tendency to draw the handle out of locking engagement with the and to push the bag wall 10 away from under the flap 12. The mutual interlock before described controls the contents of the bag substantially within the limits of the strength of the material of the bag andthe contents do not control the interlock except to cause a more efi'ective binding or locking action.

To remove the contents of the bag a person takes hold of the edge of the flap at handle attaching member 15 and pulls outwardly thereon to bring the handle to about the position shown in Figs. 5 and 6, when by a more or less vigorous I pull the inclined smoulders 1 a are closed to force the slit open so that the handle may be readily withdrawn and the flap opened. This is all done during one swinging or opening movement of the hand which takes hold of the flap.

The means for establishing. the described interlocking or binding action are susceptible of more or less modification. Figs. 7 and 8 illustrate a modified form of handle 24 which is provided at its base with short transverse siits25, while the lateralportions of the base such asin the preferred form,' may be formed up into slight shoulders or projections 26 of somewhat similar shape to the V-shape or taperingshoulders 18 before described. Or, a handle 27 may be provided with instead of havingportions punched out and set in raised position thereon may be entirely fiat including its attaching memher, as shown in Figs..9 and 10. In this case, the handle is provided with shorttransverse slits 28 at the lateralbase portions 29 and when the flap of the bag has been closed the portions 29 may be turned'back towards each other by the lingers of a person to form shoulders which would provide very reliable but not strictly automatic lockingmeans.

What I claim asnew is:

1. bag or'envelope, the combination of the bag body having a closure flap on one wall, automatic closingnieans adapted to be moved outwardly through the said wall and operable fr in the outer side of said wall to close the flap, and having means for automatically bearing on the other wall, and means for lockingly engaging said closing means with the wall which supports the flap.

3. In a bag or envelope, the combination of the bag body having a closure flap on one wall, said wall having an opening, a handle projecting outwardly through the said opening when the flap is open and operable on the flap to close it, and means on the handle for acting at opposite sides of the opening to bind the two walls of the bag together when the flap is closed.

4. In a bag or envelope, the combination of the bag body having a closure flap, a flat handle of comparatively stiff material movable through the front wall and operable on the flap to close it, the handle extending outwardly beyond the fold-line of the flap when the flap is closed, and locking means near the opposite edges of the handle for engaging the two walls and for mutually binding the two walls of the bag together when the flap is closed.

5. In a bag or envelope, the combination of the bag body having a closure flap, and a flat broad handle elongated longitudinally of the bag and of relatively stiff material operable on the flap to itself move the flap to closed position, and locking projections on the handle for engaging with the wall which supports the flap and for engaging and locking with the other wall.
