UNETED SAWS JOSEPH R. MYERS, OF CHICAGO, ILLINOIS.

FOLDING BOX.

Application filed August 16, 1920. Serial No. 403,720.

To all whom it may concern:

Be it known that I, Josnrn R. MYERS, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Folding Boxes, of which the following is a specification.

My invention relates to improvements to folding paper boxes and has for its object the provision of an improved construction of this character capable of being folded flat for convenient transportation and capable of being readily distended into box form automatically locking itself in distended form.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Fig. 1, is a top plan view with portions broken away and others shown in horizontal section of a paper box embodying the invention and shown folded flat.

Fig. 2, is a top plan view of one end of a slightly modified form of box.

Fig. 3, a bottom plan view corresponding with Fig. 2.

Fig. 4. 'a top plan view of another modified form of box. I

Fig. 5, a bottom plan view corresponding with Fig. 4.

Fig. 6, a top plan view of another modified form of box.

Fig. 7, a bottom plan view corresponding with Fig. 6.

Fig. 8, a bottom plan view of another modified form of box.

Fig. 9, a prospective view of one end of the form of box illustrated in Fig. 1 and shown distended, and

Fig. 10, a view of a section taken on line 10-10 of Fig. 1.

The form of construction illustrated in Fig. 1 comprises a folding paper box made of chip lined boxboard and comprisinga bottom 11 and side walls 12 joined thereto by the usual creases. The bottom 11 is also provided with end walls 13'joined thereto by the usual creases and corner flaps 14 are provided at the end of the-side walls 12 and joined thereto by the usual creases, being free from the end walls 13. Each of the or the locking flaps.

corner flaps 141s provided with a diagonal cut 15 defining a diagonal bending line therein. ,This cut 15 is formed in and confined to the chip side of the lined boxboard and whereby the corner flaps will be caused to bend very easily along the lines 15. Each of the end walls 13 is provided with an inwardly turned locking flap 16 overlying the corresponding fiaps 14: as shown. Each end wall 13 is provided with a securing portion 17 formed integrally therewith but defined therefrom by a slit or crease 18 so as to form a line of weakened union between each securing portion 17 and the corresponding wall 13. Each locking flap 16 is secured to the corresponding securing por-' tion 17 by wire stitches 19.

By this arrangement when'tliebox is distended by raising the side walls 12 and the end walls 13, the corner flaps 14 will automatically bend along the lines 15 and the sides thereof adjacent the side walls 12 will automatically pass under the corresponding ends of the locking flaps 16, thus automatically locking the box in distended form. as indicated in Fig. 9, the securing portions 17 yielding along the lines of weakened union 18 to permit of such automatic engagement without breaking the corner flaps It will be observed, particularly in Fig. 10 of the drawings that the slits 15 are cuts in the chip side of the box board which leave the remaining portion or facing or cover thereof unpenetrated. This construction forms a bending line which will bend very easily and at the same time the strength of the material is impaired but littleif any. By this arrangement the strain imparted to the securing portion 17 in opening is very little and the automatic operation of the box thereby greatly facilitated.- It will also be observed that in order for the automatic action of the box to take place, it is necessary that the locking flap 16 yield sufiiciently to permit folding of the corner flaps thereunder. The weakened union between the securing portion 17 and the corresponding end wall permits the necessary yielding of the locking flap 16 without undue bending or straining thereof. Thus, all that is necessary in order to distend the box is to raise the side walls 12 whereupon the box will automatically ioc'k itself in distended form.

For convenience in description I have referred to the walls 12 and 13 as the side and I tion, illustrated in Fi end walls of the box but it is .to be noted that these are only terms of convenience, it being proper to call either set of walls the side or end walls of the box.

In the form of construction illustrated in Figs. 2 and 3, the locking flaps 16 and the ,securin ortions 17 are rovided-with re istering medial creases or slits 20 which tend to increase the flexibility of the parts and thus facilitate the automatic action of the box.

slightly different "form, being defined by slit-s or creases 22 as shown.

In the form of construction illustrated in Figs. 6 and 7 the securing portions are dc fined by lines of perforations or pin holes 23 which constitute the lines of weakened union with the end walls. i a

In the form of construction illustrated in Fig.8 the'securin portions 17 are defined by straight lines 0 perforations or pin holes 24 as indicated. I v i The various modified forms of construc- 2 to 8 inclusive, are identical with that il ustrated in Fig. 1 except for the diflerences indicated and their operation is the same.

. While I have illustrated and described the referred forms of construction for carrym m invention into effect, these are capa,

' Patent is ble 0 variation and modification without departing from the spirit of the invention. 'I, therefore, do not wish to be limited Ito-the precise details of construction set forth, but desire to avail myself of such variations and 'modifications as come under the scope'of the various claims.

I Having described my invention, what I claim as new and desire to secure by Letters and end walls, the side walls being provided with corner flaps resting against the end walls, and the end wall members being provided with locking flap members overlying said corner flaps and adapted and arranged to co-operate therewith to lock said box automatically in distended form upon opening thereof, one ofsaid members being provided with securing portions joined thereto by lines of weakened but unsever'ed union and the other of said members being attached to said securing portions, substantially as described.

2. A folding box made from a single blank. of chip lined boxboard and comprising bottom, side and end walls, the side walls being provided with corner flaps restin against the end walls, said corner flaps being diagonally weakened by slits in and confined to the chip side of said boxboard, and the end Wall members being provided with locking flap members overlymg said corner flaps and adapted and arranged toco-operate therewith to lock said box automatically in distended form upon opening thereof, one of said members being provided with a securing portion joined thereto by lines of weakened but unsevered union and the'other of said members being attached vto said securing portion, substantially as described.

3..A folding box made from a singleblank of chip lined boxboard and comprising bottom, side and end walls foldable into flat or distended positions, lines for bending being defined by slits in and confined to th chip side of said boxboard.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH R. MYERS.
