'May 19, 1959 b. LEVKOFF CARTON Filed May 5. 1958 INVENTOR.

BY David Levkoff ATTORNEYS United States PatentO CARTON David Levkoif, Great Neck, NY.

Application May 5, 1958, Serial No. 733,006 4 Claims. or. 220-115 This invention relates to cartons, and, more particularly, to a carton for carrying beverage bottles and the like.

In my co-pending application Serial No. 672,662, filed July 18, 1957, I described and claimed a bottle carrier structure characterized by such efiicient use of paperboard and gluing as to ofler considerable savings in raw material costs. The one-piece paperboard carton blank described in that application comprises two substantially mirror image portions integrally connected along a substantially centrally disposed transverse fold line. Each of these portions comprises serially outboard from said adjacent edges an end wall section, a mainpanel and an opposite end wall section. Each main panel is provided with at least one longitudinal out line separating the main panel into a lower portion comprising a side wall panel and an upper portion comprising a handle panel, and a bottom panel is arranged adjacent the lower longitudinal edge of each of the side wall panels.

I have now found that the end wall sections of the erected carton can be more rigidly anchored intheir proper planar position and that a more effective central partition panel can be obtained which is securely anchored to both the handle portion and to the end Wall sections by rearranging and re-proportioning the anchor panel and the bottom panels. Pursuant to my present invention, the two bottom panels are transversely serially arranged adjacent the lower longitudinal edge of one of the side wall panels, and the portion of the anchor panel on that side of its transverse fold line proximate the other side wall panel is substantially coextensive 1ongitudinally with the handle panel and has a transverse width exceeding the distance between the lower longitudinal edge of the proximate main panel and the lower edge of the handle panel.

The bottle carrier formed from the onepiece blank of my invention comprises two juxtaposed handle panels, a side wall panel spaced from the proximate handle panel and integrally connected thereto by divider strips, and a bottom panel joining the lower edges of the two side wall panels. One end wall panel of the carrier extends substantially the full height thereof and is joined along the lower portion of its side edges to the ends of the two side wall panels and is joined along the upper portion of its side edges to a connecting panel integrally connected to the proximate ends of the juxtaposed handle panels. A second endwall panel is joined along the lower portion of its side edges to the other ends of the two side Wall panels and is joined at its top to the lower extremity of the other ends of the juxtaposed handle panels. An anchor panel is integrally joined to at least a portion of the lower edge of the second end wall panel, the portion of the anchor panel joined to the second end wall panel being folded upwardly into juxtaposition with the interior surface of the second end wall panel and being provided with an adjacent fold portion connected to the first-mentioned portion along a vertically positioned fold line. The latter portion of the anchor panel extends ice centrally of the carton to form a substantially full-height central partition and is adhesively secured along its upper portion to the inner surface of the proximate handle panel so as to anchor the second end wall in place and thus maintain the rigidity of the carrier in use.

These and other novel features of the carton structure of my invention will be more readily understood by reference to the accompanying drawings in which:

Fig. 1 is a plan view of a carton blank embodying the invention; and

Fig. 2 is a perspective view of the assembled carn'er erected from the blank of Fig. 1.

The carton blank shown in Fig. 1 comprises an approximately rectangular carton blank provided with a substantially central transverse fold line 10 which divides the main body'of the blank into two substantially mirrorimage main portions 11 and 12. A pair of transverse fold lines 13 and 14 is positioned astride the central transverse fold line 10,each of the fold lines 13 and 14 extending upwardly from the

lower edges

15 and 16 of each main portion and across a part of the main portion. Cut lines 17 and 18 extend from the upper end of each of the transverse fold lines 13 and 14, respectively, in .a diagonally upward direction to vertically spaced points along the central transverse fold line 10. Thus, the two cut lines 17 and 18, the pair of transverse fold lines 13 and 14, the

lower edges

15 and 16 of the twomain portions and the central transverse fold line 10 define two substantially symmetrical end wall sections 19 and 20. Each of the main portions 11 and 12 is provided with three

longitudinal cut lines

21, 22, 23 and24, 25, 26, respectively. The three longitudinal cut lines in each main portion are spaced from one another in a, laterally staggered relationship so as to define in each of the main portions two hinged

divider strips

27, 28,.and. 29, 30, respectively. The divider strips are appropriately hinged by

transverse fold lines

31, 32 and 33,134, respectively, symmetrically placed between the inner pair of transverse fold lines 13 and 14 and an outer pair of, transverse fold lines 35 and 3,6. These

outer transversefold lines

35 and 36 are equally spaced from the central transverse fold line 10 and define the outermost boundaries of

side wall panels

37 and 38 in the main portions 11 and 12,

provided with

end wall sections

41 and, 42 advantageously. integrally connected to the two main portions alongythe outer pair of

fold lines

35 and 36, respectively. -.-The end wall sections are also advantageously providedwith foldingoutboard glue panels 43 and 44 integrally connected to the end wall sections along a pair of transverse fold. lines 45 and 46. The lower longitudinal edge 16 of the. side panel 38 is defined by a fold line by.which this.

wall panel is integrally connected to a'pairof

bottom walls

47 and 48. The lower longitudinal edge 15 of the other side wall panel 37 is provided with a. glue flap 49, and one of the handle, panels 39 and 40'is provided with a glue flap 50. i

The center anchor panel 51, as shown in Fig. l, is integrally connected to one of the symmetrical end wall sections 20 alongthe lower longitudinal edge 16 there-.. The anchor panel is provided with a transverse.

of. fold line 52 substantially aligned with thecentra'l transverse fold line 10. The portion of the anchor panel on that side of its transverse .fold line which is integrally. connected to the end wall section 20 is; provided with r a longitudinal :cut line 53, positioned between .the out-- board longitudinal edge of the anchor panel and the longitudinal fold line 16 and thus divides this portion of the anchor panel into two

sections

54 and 55. The other portion 56 of the center anchor panel disposed on the side of its transverse fold line opposite the longitudinal cut line 53 is proportioned so as to be substantially coextensive longitudinally with the handle panel 39 and to have a transverse width exceeding the distance between the lower longitudinal edge of the proximate main portion 11 (i.e. the longitudinal fold line 15) and the lower edge of the handle panel 39 (i.e. the uppermost longitudinal cut line 21). Thus, when the anchor panel 51 is folded over about the line 16, the lowermost extremity of the anchor panel portion 56 comes into juxtaposition with the handle panel 39. When the handle panels are provided with arcuately

curved handle openings

57 and 58 as shown in Fig. 1, the lowermost extremity of the anchor panel portion 56 is provided with a matching arcuate contour 59.

The bottle carrier of my invention is assembled as follows:

Glue or other adhesive is applied along the arcuate lowermost edge 59 of the anchor panel portion 56 and along the opposite diagonal outboard corner portion 60 of the anchor panel as indicated by the stippled areas shown in Fig. l. The anchor panel is then folded upwardly and inwardly as a unit about the fold line 16 so that its glued areas make contact with the

handle panels

39 and 40. The two

end wall panels

41 and 42 are then folded upwardly and inwardly about the outer

transverse fold lines

35 and 36, whereupon glue is applied to the then upper surfaces of the glue flaps 43 and 44. The lowermost bottom panel 48 is thus folded up over the other bottom panel 47, and one side of the thus-folded blank is thereafter folded upwardly and over about the aligned transverse fold lines and 52 until the glue panels 43 and 44 come into juxtaposition with and are secured to the lateral end of the anchor panel portion 56 opposite the transverse fold line 52. In the final operation, glue is applied to the glue flaps 49 and 50, and these flaps are then folded over into contact with their cooperating bottom panel and handle panel, respectively.

The thus-assembled carton is then erected simply by applying compressive pressure to the two lateral ends of the folded structure. As the pressure is exerted, the

divider strips

27, 28, 29 and 30 swing outwardly and permit the

side wall sections

37 and 38 to swing outwardly to the final erected position shown in Fig. 2. In this position it can be seen that the portion 56 of the anchor panel forms a substantially complete central partition for the carrier. The resulting vertical fold between the anchor panel portions 56 on one side and

portions

54 and 55 on the other side of the transverse fold line 52 insures the rigidity of this fold line in a vertical position, and the vertical position of this fold line of the anchor panel is maintained by the gluing of the anchor panel portion 56 :between the

handle panels

39 and 40. Thus, inasmuch as the position of the fold about the line 52 is maintained in a fined vertical position, the lowermost end of the fold line 52 maintains the lower end of the central transverse fold line 10 in a fixed position by virtue of the integral fold along the longitudinal fold line 16 between the end wall section 20 and the adjacent portion 55. By thus fixing the position of the lowermost central portion of the end wall composed of the symmetrical end wall sections 19 and 20, and by anchoring this assembly by the gluing of the laterally extending portion 56 of this panel to the

handle panels

39 and 40, the resulting end wall structure remains rigidly upright and securely holds the bottles in the end wall sections. At the same time, the strain of the weight of bottles in the loaded carrier is distributed from the bottom edge of the end wall sections to the entire area of the handle panels. The entire carrier assembly is held locked in its erected position -by engagement of the juxtaposed locking 4% notches 61 formed in the glue panels 43 and 44 with the proximate locking notch 62 formed in the

bottom panels

47 and 48. Inasmuch as this locking action resists the normal resilience of the folded and erected carton, the lock holds firmly and securely.
