Fig. 9 is an extended plan view of a blank showing a further modification therein over the blank of Fig. 1.

Fig. 10 is a perspective view of a partially erected carton made from the blank of Fig. 9.

Throughout the several views of the drawings similar reference characters are employed to denote the same or similar parts.

Each of the several cartons disclosed in the drawings are formed from a single blank'each of which is modified to produceits modication of the carton and which cartons are basically the same. The common basis for the several cartons of thev present invention consists in each having a bottom or base member from the four sides of which extendwalls each formed of an inner and an outer member. In each carton two of the opposite walls, generallyreferred to as side walls, have for a portion of their height. spaced apart inner and outer members 'with the remaining portions of said inner and outer wall members contacting one another with a top member at the upper end of the hollow portions of the walls.

Specifically and referring to Figs. 1 to 3, iriclusive, the blank comprises a rectangular base portion I5 bounded by score or fold lines I6, I1, I8 and I9. The score or fold lines I6 and I8 are of greater length than the score lines I1 and I9, and in accordance with usual practice will be referred to as the sides of the carton although the remaining lines may be the said sides since the generallyreserved for the longer oi the bounding walls.

The score of fold lines I6 and I6 respectively hlngedly connect to the base I similar extensions and 2| and since these extensions are substantially identical only one of them will be described in detail. Accordingly, extension 2|! is provided with a plurality of score or fold lines 22, 23, 24,25 and 26 which divide the extension between the fold line I6 and end of the blank into panels 21, 28, 29, 30, 3| and 32. The panel 21 forms in the erected carton the outer wall member for the side walls and has its ends defined by score or fold lines 33 and 34 which hingedly connect therewith corner pieces 35 and 36. The panel 28 forms the upper portion of the side wall inner wall member and has its ends defined by cut lines 31 and 38. The panel 29 forms the side wall top wall member in the erected carton and lies parallel with the base I5. The ends of the panel 29 are defined by cut lines 39 and 40. The panel 30 forms the lower portion o the side wall inner wall member of the complete wall and has its ends defined by score or fold lines 4I and 42, and the said panel 30 is provided near its ends 4I and 42 with elongated apertures 43 and 44 cooperating, as will later be made clear. with end wall locking lugs for securing the walls in erected positions. The panel 3| is of substantially the same width and length as the panel 29 and has its ends defined by cut lines 45 and 46 and this panel constitutes the bottom of the hollow side walls. The: panel 32 is ya glue flap of a length and a width substantially equal to that of the outer wall member panel 21 and to which it is attached by suitable glue or adhesive such as 41 illustrated as carried by the inner surface of the outer wall member 21. The ends of the glue flap 32 are defined by score or fold lines 48 and 49.

The score or fold lines 33, 4I and 48, at one end of the wall members and glue ap, are in alignment with the base member score or fold line I1 and the score or fold lines 34, 42 and 49. at the other ends of the wall members and glue flap are in alignment with the base score or fold line I9. The glue flap 32 has through its ends score or fold lines 48 and 49 hingedly connected therewith end wall vertical braces 56 and 5I which lie in the erected carton, adjacent the end wall outer wall member. The lower portion of the side wall inner wall member panel through its ends scores 4I and 42 has hingedly connected therewith end wall lateral and vertical braces 52 and 53. Said braces 52 and 53 have their other defined by score or fold lines 54 and 55 and act as hinged members for connecting thereto end Wall vertical braces 56 and 51. The said end Wall vertical braces 50 and 56, and 5I and 51 have hingedly connected between them end wall lateral braces 58 and 59- through score or fold lines which are in alignment with score or fold lines 25 and 25. Similar end wall lateral or transverse braces 60 and 6I are located between vertical braces 56 and 51 and end wall vertical braces 62 and 53, being separated by hinge or fold lines in alignment with an extension of score or fold line 22. The end wall vertical braces 62 and 63 are adjacent to corner pieces 35 and 36 being separated therefrom by score lines in alignment with score line 22.

TheA corner pieces and 36 are each provided with a diagonal fold or score lines 64 and 65 and form, as will later be made clear, a bellows corner between the said side wall outer members and end wall outer members. As will be noted the portion of each corner pieces 35' and 36 between its respective diagonal fold lines 54 and 65 and the side wall outer member is provided with adhesive which engages a corresponding portion of the end wall vertical braces 50 and 5I.

The base panel I5 has hingedly connected to its ends through the score or fold lines I1 and I! similar extensions 96 and 81 which form shouldered or stepped end walls and since said extensions are substantially identical it is deemed sumcient if but one of them be described, in detail. Accordingly, extension 66 is provided with a plurality oi score or fold lines 68, 69, 10 and 1 I, thereby providing between the score or fold line I9 and the end of the extension 66 panels 12, 13, 14, 15, and 16.

The panel 12 is of a length equal to the width of the base blank and has its ends dened by score or fold lines 11 and 18 which vare in alignment with the base scores I6 and I8 and said score or fold lines 11 and 18 hingedly connecting to the said panel 12 the corner pieces 36. The panel 13 has its ends defined by cut lines 19 and 80 which are in alignment with the score orl fold lines 11 and 16. The panel 'I3 is of -a length substantially equal to the width of the base member I5 and forms in the erected carton the top portion of the end wall inner Wal1 member and is disposed between the side walls inner wall member top portions 28. The panel 14 is shorter in length than the panel 13 and is substantially equal to the distance of said carton between its side walls inner wall members top portions 28 and the panel 13 forms the top wall member or step for the hollow end wall. The panel 15 in the erected carton forms the lower portion of the end Wall inner wall member and is of a length substantially equal to the length of the panel 14 which is equal to the space between the said carton side walls inner wall members lower portions. 'Ihe panel 15 has projecting from it, near its outer ends, lugs 8| and 82 which are adapted to enter the elongated apertures 43 and 44 for locking the carton walls in their erected positions. The panel 16 in the erected carton forms a spacer for spacing the lowermost end of the end wall inner wall member lower portion from the corresponding end of the end wall outer wall member. The upper portion of the end wall inner Wall member panel 13 has projecting from it beyond the panel 14 lugs or tabs 83 and 84 which, in the erected carton are projected behind the top wall or shoulder of the side walls in holding the carton in erected position.

In the manufacture of the carton, a blank, as just described, is provided cut to a contour as illustrated in Fig. land with adhesive thereon as illustrated at 41. The carton blank is then folded along the score or fold line 25 thereby bringing the glue ap 32 and bottom side wall panel 3| into face contact with top wall or shoulder panel 29 and inner wall member the upper and lower portions 30 and 28 of side wall. The blank is then further folded on the score or fold line 22 thereby bringing the glue ap 32 and adjacent brace portions 50 and 5I into engagement with the adhesive 41 of outer wall member 21 and corner pieces 35 and 36. In other words both side wall extensions 20 and 2| are now folded to the position in which the extension 2| is illustrated. A transverse cross section of this folded blank is as illustrated in Fig. 3 and it is in this position that the blank is shipped to the user.

It should be noted that the side Wall bottom panels 3| are not secured to the carton bottom or base member I5 but are free thereof and that the glue flap 32 is the only securing factor of the side walls.

When the user desires ,to utilize the carton as for the reception of merchandise to -be shipped or displayed therein, he lneed only raise the folded side wall iiaps from their outwardly Hextending positions to a position normal to or vertical of the carton base. -In the event that difculty is encountered in breaking the scores so that the lower portion of the inner wall mem ber, the outer wall member, the step or wall member and the bottom wall member take their proper position of being normal to one another, the said scores may be broken prior to the set up of the carton. This is illustrated in phantom lines at 85 and 8S in Fig. 3. In other words while the blank is still in the extended position the bottom wall member may be lifted and swung outwardly thereby raising the lower portion of inner wall member from its -iiattened position and outwardly swinging the shoulder or top wall member. With the said side wall members in the position of Fig. 3 they may be swung to be normal to the carton base or bottom.

With the side wail members in their erected position as illustrated in Fig. 2 the end wall braces may now be swung to be transverse of the bottom member or panel i5 as illustrated in Fig. 6. Due to the connection of a portion oi each bellows corner to the end wall vertical brace member 5t) or 5i, the shifting of the said braces will cause an upward swinging of the end wall outer member or panel l2 so that when the said braces are in their transverse position the end wall extension is vertical or normal to the bottom or base member i5. The remaining panels of the end wall extension may now be folded to be normal to one another thereby enclosing the braces and the end wall members locked by engagement of the lugs ti and 82 in the elongated apertures 13 and it and the intersection of the tabs or lugs d3 and 8S beyond the shoulders or steps 29 against the edges 3Q and #it thereof.

It will be noted particularly from Fig. 6 that the end wail braces are box-like in cross' section for vertically and laterally spacing and bracing the end wall inner and outer members. At the same time the end wall inner member is prevented from displacement due to pressure from the interior of the carton. It will further be noted that there has been provided a carton in which the scores may -be pre-broken resulting in greater ease of assembly and less pressure required to assemble the carton. It should also be noted that by the present construction the side walls need not be set up to their iinal position before the raising of the end wall, in iact ease in erecting the carton will be experienced if when the side walls are brought to a partial erected position the end wall is likewise acuated and both the side walls and outer end wall member brought to a nal position simultaneously.

It should .be noted that the upper portion, of the side wall inner wall member has glue or adhesive 81 thereon whereby it is secured to one face of the glue flap 32 and through which said side wall inner wall member panel 28 is secured to the side wall outer wall member panel 21.

The modification of the invention illustrated in Figs. 4 and 5 is quite similar to the carton illustrated in Figs. l'to 3 except that the step or shoulder is placed on the outside of the carton instead of on the inside thereof. To accomplish this the side wall inner wall member panel is formed tothe full height of the carton while the outer wall member'l is made up of two panel portions, 88 and 89 separated from one another by panel portion 90 which is -deilned by the fold or score lines Si and 92. In other words the side wall top wall member isshifted to'provide the outer wall member with an upper and a lower portion. A further modification occurs in the formation of the side walls extensions in that the glue aps t2 are shortened to correspond with the width of, the lower portions of the outer wall member panelsd. The end wall braces may be left to have the same contour as that of Fig. l and is so illustrated in connection with side wall extension tu' of Fig. 1. The braces are illustrated in connection lwith side extension 2i Aof Fig. i shows the`lateral brace panel 93 as at the height of the outer wall lower portion and will therefore extend intermediate the height of the end wall inner and outer wall members as clearly illustrated in the right hand haii of Fig. 6. it should be noted, however, that these braces may be formed to be the saine at all four corners of the blank or they may be used as illustrated, one having a transverse brace at the lower end thereof with a second trans verse brace either at the top or intermediate the top and bottom. The end wall extensions of this modication in Fig. el are formed to provide end wall of uniform thickness throughout their height instead of having a step or shoulder in= termediate this height.

Accordingly the end wall extensions bt and tl are each modified to the extent that the wall inner wall member is formed from a. single panel instead of an upper portion panel and a lower portion panel. The extension ed therefor has hingedly connected to its outer wall member panel l2 through the score or fold line @t a panel tl which in the erected carton forms the end wall top wall member, the other side of the panel iid is dened by a fold or score line t5 which hingedly connects thereto the end wall inner wall member panel et. The other end of the panel @e is defined by the score or fold line li outward of which is the spacer iiap or panel it. The inner wall member panel @d is of less width than the outer wall member panel l2 and the top wall member panel has a widthadjacent the said outer wall members panel equal thereto while its other side, adjacent the inner wall member panel is of a width equal to the width of thesaid inner wall member. For this reason the ends of said top wall. panel Sti are contoured or biased as at el and te, with said ends, in the erected carton, overlying the side walls exterior shoulders or steps 2S i'n a plane thereabove.

The blank of Fig. 4 is shipped to the user in substantially the same condition as that of Fig. 1 and as illustrated in Fig. 3 and this blank is set up in substantially the same manner.

The resulting carton, however, see Fig. 5, has end walls of uniform thickness throughout their height while the side walls are thicker at their lower portions than at their upper portions with the step exteriorly of the carton sides.` This construction results in the end wall top wall ing a body portion 99 the opposite ends of which are similarly subdivided by score or fold lines |00, |02 and |08 to provide on the body portion panels |04, |05, |08 and |01. The' said panels are folded to be normal to one another with the panel |01 acting as a glue flap for attaching the rectangular tube, resulting from the folding of the panels, to the cover body portion 00. It will be noted that the panels and |01 are shorter than the panels |04 and |00l thereby resulting in tongues |00 and |09 at the ends of the tubes. It will also be noted that the said tongues extend from the inner wall of said tube. The resulting cover is as illustrated in Fig. 8 being shipped to the user with the tubes flattened inwardly of the cover body portion 90.

In order for the user to apply the lid or cover to the carton the tubes are bent on their score or fold lines to be normal to the said body portion 99. This results in the tongues |08 and |09V having provided between them and the body portion a space ||0 which is substantially equal to the thickness of the board from which the carton of Fig. 5 is formed. The lid is applied by inserting the projecting portions of the end walls top members, or contoured portions Bland 90, beneath the fingers |08 and |09 at one side of the lid or cover and slightly upwardly bending or raising the other side of the cover as illustrated in phantom lines in Fig. 5. The upwardly raised portion of the cover or lid is then lowered to bring the body portion of the cover against'the end walls top members 96. As the fingers at the free end of the cover or lid engage the projections of the end wall top members they are pressed inwardly until they are beneath said projections whereupon they spring to their normal position beneath said projections and thereby lock the cover in position. This is illustrated clearly in Fig. 6 where it discloses the fingers |08 and |09 of the cover as beneath the end walls top wall projections.

The remaining modification illustrated in Figs. 9 and 10 is directed to a carton in which the side walls are provided with a step or shoulder interiorly of the carton, with, however the end walls of double thickness instead of appreciable width. In this construction the end walls merely consist of an Ainner and an outer wall member with no top wall therebetween and the vertical and transverse braces of the construction heretofore described are eliminated. Accordingly, the end wall extension 66" and 6'!" of Fig. 9 consists essentially of panels .lll and ||2 divided from one another by a score or fold line ||3. The panel constitutes the end wall outer wall member while the panel H21 constitutes the inner wall member and in order to lock the said wall members in operative positions the said inner wall member is provided with downwardly projecting lugs ||i4 and ||5 to engage behind the side wall shoulder and is further provided with laterally projecting legs l I6 and |I`| to engage behind the lower portion of the inner wall member.

The blank of Fig. 9 is shipped to the user in the same manner as the blanks heretofore described and the set up is substantially the same.

It is lsometimes desirable to have the inner surface of the set up carton or box part (lid) the same as the outer surface particularly when printed. To accomplish this the inner wall member ||2, see extension 66' -of Fig. 9, may have hingedly connected thereto as by a score or fold line IIB a panel ||9 of an area substantially equal to the carton base panel i5. To assist in retaining the extension ||9 in position, it has projecting from its sides locking tongues |and |2| f each adapted to enter a similar slot |22, see Fig. 5 10, formed by a cut |23 in the innerwall member lower portion 30.

From the foregoing it will be noted that each of the modifications o f the present invention is basically the same, each having side walls of appreciable width for a portion of their height and with the said side wall free of the bottom or base of the carton. By this construction the objects initially set forth are attained with a resultant carton having greater ease in erection and considerably greater rigidity and strength in the erected carton.
