Letters Patent No. 1,513,608, issued to me 'october e8, 1924,
described and claimeda having rib-shaped legs paper receptacle doubled portions integral Darrow While such receptacles are practical in use, the operation of gluing and folding the said leg portions involved undesirable time and ex nse. a Y A ne of the objects of the present invention is to, provide strong and: durable receptacles of the neral type explained in the patent referr i' to, but 'oflesser cost of production,
en receptacles to said patent, it is impractical to'ship the blanks in flat condition to be then converted to set-up condition by the customers Aor users, because of the necessity of either stitching or 'adhesively connecting overlapping portions of the receptacles. Therefore another object of the invention isv to provide paper 'receptacles which can be stored or shipped 1n and which can be manually converted to set-up condition without A rel uiring any stitching or gluing, thereby efecting economy in production and the costs or storage. Y L v With said objects in view, and others ywhich will be referred to, the invention consists in the receptacles substantially asherelnafter described and claimed. 0f the accompanying drawing Figure 1 is a perspective view ofthe blank i with one marginal portion folded and secured and the opposite marginal being iolded and'secured.- .y
Figure 2 is a perspective view of. the complated receptacle. f, v
Similar reference characters indicate similar parts or features in both of the views. The blank from which the' box or recepportion .prior to are produced according'l tacle is made comprises a central rectangular portion'12 (Fig. l) which is to form the bottom of the boxv or basket, the blank being slitted and being also creased or scored-as indicatedby dotted lines-tol form two opposite end wall sections 13 having foldable aps 14 each of which has end tongues 15, and two opposite side Wall sections 16 having end flaps 17 and marginal iaps 18, the latter having free end tongues 19. The blanks are so 50 cut that each flap 18 has abrupt end edges20 to serve as abutments asv hereinafter expla1ned. l
When the blanks are cut, they are so slit- 'ted that when -a blank is converted to the set-l.65
up condition illustrated by Figure 2, pory tions 21 thereofextend downto form legs which in use support the bottom of the receptacle a slight distance above or away from a shelf or its equivalent; v
In operation, the blanks are treated with paraine wax or suitable equivalent thereof, so that the receptacles will be moisture-proof, This is done while the blanks are at'with.,
v'no portions folded. Then sucient wax is removed along the flaps 18, and preferably along the outerareas of the wall sections 16,
so vthat When'adhesive is properly applied such as indicated by the shaded area of the flap at the left of Figure then folded a's shown at the right of said Figure 1, both of said flaps-18, will be rigidly f secured. Itis important that the tongues -19 1, and said flap 30,
shall be free and not adhesively secured to B6 anything.y
The blanks so prepared are ready to be stored or shipped, and they are readily converted to the set-up condition illustrated by' Figure 2, by manual operations. To sol con` vert a blank, the up and their end fla' each other, and the ot are'turned -np outside flaps 14 are lfolded in over the flaps 17 and s17 swung in toward er two wall sections 13 two sections '16 are' turned 9 the iaps 17 and their' over `the free end tongues 19 of the other '95 two wall sections, and the ends of the tongues v 15 automatically snap into engagement with the abutments 20. Such engagement locks the walls 13 so that they cannot swing out, because the flaps 17 and the tongues 19 are.
enclosed within portions of said walls, and the other two walls 16, 18, can not swing out because the up ered es of their daps 17 and tongues 19 t close y under the fold line portions 13, 14. This will be clear when it is understood that the blanks are so shaped that when the aps 17 and the tongues 19 are swung in or folded, the upper edges of said daps and tongues are parallel or in 110 alinement.
glued or free is that if they were adhesively secured to the flaps 17 (see the ri hthand portion of Figure 1) they would o er resistance to the' inward folding of the daps 17 toward each other when setting the blanks up to receptacle form. @wing to the fact that said tongues 19 are integral with two of the side walls' and are tightly .enclosed between portions of the other two side walls, they edect avery strong reinforcement for the four upper corners of the receptacle.
When the manually-effected conversion of the blank to receptacle condition has been eiected as described, it not only. results in reinforcing the upper portions of the walls of the receptacle by making themdoublethick, but also causes the extreme edges or tops of the walls to be -smoothly rounded. And such double thickness also serves to compensate for such weakening of the 'walls as may result from forming such Ventilating openings therein as are illustrated in the drawing. The Ventilating openings referred to exist partly in single-thick wall areas and partly in double-thick wall portions. As illustrated,l the said Ventilating openings are providedV by forming'recesses in the edges of the aps da 18 and elongated openings in the wall sections 16, which recesses and openings register with `each other` when the flaps 18 are folded inwardly and secured. rlhis provides boxes or receptacles which have amply strong upper s wall portions as just referred to, without requiring the amount of material that would have to be employed if the walls were of double-thick material throughout, and the vsaid walls haveample vprovision for ventilag@ tion without being weakened by the openings therein.
llt it is desired that the boxes-shall loe-per- The reason for leaving the tongues un-v I animas manently secured in setup condition, such result ma be attained by applying staples through t e aps 14, 17, and walls 13, 1n a manner similar to that illustrated at cin my Patent No. 1,513,608 hereinbefore referred to.
To facilitate an understanding of the invention, the sections 13 and their flaps 14 are referred to as the end walls, and the sections 16 and their a s 18 are referred to as the side walls of the receptacle, although the 35 drawings represent the receptacle as square. As illustrated by Figure 2, all of the walls diver e, this being the preferred vform for berry oxes to enable a large number of them to be nested when empty, and to facilitate 8@ the filling and emptying -whenthe contents are of a berry type.
An important feature of my-invention resides in the fact that when the blank is set upto receptacle form, the upper edges of the tapering end naps 17 of theside wall sections lextend along and snugly lit the inner surfaces of the folds of the end wall flaps 14, and therefore resist tendency ofg the Haring side walls to swing outwardlyI so as to perae. mit separation of the abutting tongues 15 and notches 20.- L
