This invention relates to improvements in folding egg cartons.
One of the important features of the invention resides in an egg carton for' the retail sale of eggs, which when in its original set up position receives a dozen eggs but which may be broken in half and divided into two separate carton units, each unit adapted to contain a one-half dozen eggs. By such construction of carton, eggs may be originally packed, shipped, and placed on sale in dozen lots and should a dealer have occasion to make a sale of but one-half dozen eggs, the carton may be broken centrally into two separate units without disturbing the eggscontained therein.
Another feature of the invention is to provide a cushioned egg carton of the kind shown in the Levkofi Reissue Patent No. 19,625, granted June 25, 1935, wherein the carton is constructed of a single blank of cardboard having a longitudinal partition and pivoted cross partitions which divide the body of the carton into twelve individual cell compartments for the respective eggs of a dozen lot. However, when breaking the carton midway of its length to divide the same into two separate carton units for dispensing half dozen lots, an additional cross partition is necessary to close one end of one of the carton units, and for this purpose, I provide a separate supplementary cross partition which may be normally nested within the carton and readily inserted into position to close one end of one of the canton units when the carton is broken to divide the same. By this construction, I am able to construct the carton from a blank of less stock than would be required if the supplementary .cross partition were formed from the same blank as the other cross partition.
Another feature of the invention is to provide a one-piece cushion bottomed egg carton of the type having a fixed longitudinal partition, and cross partitions hingedly connected to the front and rear walls of the carton body wherein the two and cross partitions fold inwardly in opposite directions to enable the cutting of the carton from a single blank of cardboard stock With these and other objects in view, the in-.
vention resides in the certain novel construction,
, combination and arrangement of parts, the easential features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawings, in which:-- Figure 1 is a plan view of the egg carton in collapsed position.
Figure 2 is a fragmentary top plan view of the 5 carton in set up position with part of the cover broken away.
Figure 3 is an enlarged detail vertical sectional view on the line 33 of Figure 2.
Figure 4 is a perspective view of the supple- 10 mentary cross partition. 7
Figure 5 is a fragmentary perspective view of the set up carton broken into two separate carton units, a portion of one of the units being broken away to illustrate the supplementary l5 Figure 10 is a view similar to Figure 7 but 2 showing a modified form of supplementary cross partition. I
Figure 11 is a perspective view of the modified form of supplementary partition.
Referring to the drawings by reference char- 30 acters, the letter A designates the blank of material from which my improvedcollapsible egg carton is constructed. The material A is preferably stifi cardboard of the type customarily used in the construction of egg boxes and the 35 blank shown in Figure 9 is of substantially rectangular configuration. The blank A is scored transversely from top to bottom on the lines It), H, i2, it, It, l5, l8, l7, and I8. The material beyond the score line It] constitutes a cover lock 40 'ilap IS, the free edge of which is provided with spaced locking tongues 20. The material between the score lines l0 and H constitutes a cover 2|,
" while the scorelines H and I2 divide the blank The score lines J3 and M 45 into a rear wall 22. I are broken score lines and connect with feet 23 which are cut from the material forming the bottom wall sections 24 and 25. The bottom wall section 24 is disposed between the score lines l2 and I3 whereas the bottom section 25 is disposed between the broken score line IS-Yand the continuous score liue IS. The material between the score line H and the-broken score lines l3 and I5 provides a pair of longitudinal partition walls 2|.' The longitudinal partition as will be hereinafter explained.
The unnotched portions of the longitudinal partitions formed by folding the partition walls fiat against each other provide spaced projections along the top of the longitudinal partition which are adapted to enter passages preferably in the form of slots in the transverse partition about to be described during setting up or collapsing of the carton.
The material between the score lines It and the broken score. line I! constitutes a. front wall 30 while the material between the broken score lines I! and 8 constitute a topwall 3|, while the bottom edge of the blank below the broken score line l8 provides an attaching flap 32. I
Cut from the top wall 3| is a plurality of cross or transverse partitions 33, all of which are pivotally connected to the front wall 30 and attaching fiap'j32 ,on .the dotted lines 34. The cross partitions 33 are so cut from the top wall 3| that the end cross partitions both fold inwardly and a bridge piece 35 is formed midway of the blank, there being four cross partitions on the left side of the blank and only three on the right side, and which when-swung down to their set up position,
divides thecarton into twelve separate cells, it
being-understood that the cross'partitions bridge the central longitu'dinal partition as shown in Figure 6.
The transverse partitions 33 are notched inwardly. at their mid-portions from theirinner sides to provide notches or passageways 31 which are preferably shown as slots. Each transverse or cross partition is foldable centrally and transversely upon its fold line 38 and which line extends from the innerend of its passageway 31 to .the top or head end of the cross partition. The 'unnotched midportions of the transverse partitions are in transverse alinement with the respective slots or cut outs 23 and are of a width equal to or less than the width of the slots or cut outs to be freely received therein during the settting up of the carton. All of the cross partitionswith the exception of the secondiand third partitionsfrom the left in Figure 9 are provided at their free bottom edges with tongues 40 which are received in slots 4| formed in the adhesively secured to the rear wall;
The end partitions 33 are also provided with outer corner tongues- 42 which are receivedin slots 43 in the front and rear walls when the said end cross partitions are swung to their down position.
The carton isinitially set up to assume the position shown in the several views of the drawings, whereuponthe longitudinal partition walls 21 arefolded fiat against each other on the fold line l4, and these two walls are fixedly secured together by an adhesive'to prevent outward spreading of the walls. After forming the central longitudinal 6 of the drawings, whereupon the bottom wall sections 24 and 25 extend upwardly and inwardly into meeting engagement from the rear and front walls respectively, and the front and rear walls extend upwardly and outwardly at a slight angle. The rear wall 22 is of a slightly greater height than the front wall and has the cover 2| hingedly connected thereto, whereby the cover may be swung over the box body and secured closed by engagement of the hook 20 with the triangular shaped portions 44 which connect the transverse partition walls with the front and rear walls. When the box is initially set up as shown in Fig ure 6, the legs 23 extend downwardly from the meeting edges of the bottom wall sections and provide a support for thecentral portion of the bottom wall. By folding the partition walls 21 flat against each other and fixedly securing the same together, the cut outs 29 provide notches 45 in the top of the central longitudinal partition and the open mouths of the notches are of a width at least equal to the length of the folded mid-portions of the transverse partitions and are disposed in alinement with thefolded mid-portions of respective transverse partitions 33.
After the carton has been assembled in the manner just described, the transverse partitions 33 are folded inwardly to assume a vertical position, the slots 31 receiving the longitudinal partition while the tongues 40 extend through the respective cut out slots 4|. From this set up position, the body of the carton may be folded fiat as shown in Figure 1 for it is only necessary to press the front and rear walls toward each other,
whereupon the top 3| and bottom wall sections 24 and 25 willmove to a position substantially parallel to the fixed walls 21 of the longitudinal partition. To open the carton for use, the reverse action takes place, that is the front and rear walls are moved away from each other, the top wall 3| tending to limit the spreading of the top of the front and rear walls, while the fixedly attached partition walls 21 limit outward spreading of the inclined bottom wall sections 24 and 25. Upon opening of the carton body, the midportions of the transverse partitions freely enter the notches 45, while the unnotched portions of the longitudinal partition enter the slots or passageways 31 thereof, after which the transverse partitions may be swung to vertical positions. Thus it will be seen that the carton body is set up for use to receive the eggs to be packed, the longitudinal partition and the seven cross partitions serving to divide the carton body into twelve egg receiving cells. 7
The construction of egg carton above described is substantially the same as that set forth in the Levkoff reissue patent ,above referred to, with the exception that both of the end cross partitions 33 fold inwardly, andby this arrangement, it is possible to avoid waste of material due to the. fact that no end cross partition extends beyond the confines of the rectangular blank. This feature alsonecessitates the forming of two cross partitions 33' and 33" from an area of material approximating the area from which the other cross partitions are formed. The cross partitions 33' and 33" swing inwardly in opposite directions and are dis'posedadiacent the left end cross partition 33 shown in Fig. 9. The
cross partition 33' swings in the same direction as the next adjacent end cross partition 33 whereas the cross partition 33" swings inwardly in the same direction as the remaining cross partitions 33.
Cal
The blank A is provided with a weakened tear line 46 which extends centrally and lengthwise of the blank from one end to the other, portions of the weakened line being in the form of perforations 41 whereas other portions of the weakened line are slits 48. The weakened line 43 divides the carton into two separate sections B and C, the section B having four cross partitions whereas the section G contains but three cro'ss partitions 33. The weakened line 46 however passes to the left of the bridge piece to permit the bridge piece to remain with the carton section C for a purpose now to be explained.
Assuming that the carton has been erected in the manner hereinbefore explained and packed with a dozen eggs and it is desired to break the carton into twoseparate sections as shown in Figure 5, and which are identified by the letters B and C. In view of the fact that section B contains four cross partitions, two of the cross partitions constitute end walls, therefore the section B constitutes a complete carton unit.
In view of the fact that carton section C contains but three cross partitions 33, it is necessary to provide a supplementary cross partition 49, the same being shown per se in Figure 4 of the drawings. The supplementary cross partition is constructed of cardboard and includes a body portion 50 having a head portion 5| foldable from the body on the line 52. The body 50 is of a shape conforming to the cross sectional shape of the carton body and is provided with a vertical slot 53 extending upwardly from the bottom edge and a slot 54 in alinement with the slot 53 and which extends into the head portion 5|. The bottom edge of the supplementary cross partition 49 on opposite sides of the slot 53 is provided with feet 55.
The central longitudinal partition of the carton section C adjacent the open end thereof, is provided with a hook portion 55 which passes through the slot 54 in the supplementary partition 49. When the carton is collapsed as shown in Figure l, the supplementary partition lies flat against the folded carton; but after breaking of the carton the supplementary partition 69 is swung into position by folding the same on the line 52 which crosses the bridge piece 35 to flex and abut the central longitudinal partition as shown in Figure 7, the slot 53 receiving a portion of the central longitudinal partition while the feet 55 extend into a set of end slots M. It will thus be seen that the supplementary partition 49 is locked in position and constitutes an end wall for the carton section C.
Figures 10 and 11 of the drawings show a slightly modified form of supplementary cross partition designated 56 having a slot 51 extending inwardly from the bottom and centrally located, there being downwardly extending feet 58 on opposite sides of the slot. By reference to Figure 10, it will be seen that the modified form of supplementary partition is inserted vertically between the end of the central longitudinal partition and the bridge piece 35, the slot 5? receiving the central longitudinal partition while the feet 53 extend through a-set of the end slots 5!. This form of cross partition is merely laid flat on the collapsed carton prior to its insertion into position.
, While I have shown and described what I consider to be the preferred embodiments of my invention, I wish it to be understood that such changes and alterations as come within the scope of the appended claims may be resorted to if desired.
Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States, is:.
