Abstract
REINFORCED INTEGRAL HANDLE FOR CARTONS
Abstract A carton having a reinforced carrying handle is formed from a single blank of paperboard or the like. The carton has foldably connected panels defining a rectangular cross section tube with flaps extending from its lower end to define a closure. The other end of the panels is provided with a closure and carrying structure consisting of closure flaps extending from one pair of opposed panels and handle-forming flaps extending from the other pair of opposed panels. The flaps are arranged in lapping relationship with each other. The handle-forming flaps have central handle forming elements which can be erected with the distal portion of the flaps maintained in adhered relationship to each other and to the closure flaps. The handle forming elements are defined by score lines and a narrow band of tear resistant material is adhered to each handle-forming panel adjacent the score lines to prevent tearing of the handle-forming panels when the handle-forming elements are erected and disposed in confronting relationship with respect to each other.

Description
REIM~ORCED INTEGRAL HA~DLE FOR CARTONS
This invention relates to cartons and, ~ore particularly, to cartons with integral reinforced handles which form part of the closure structure of the carton. The handles may be folded flat against the top wall of the carton until they are needed for carrying the carton. They can then be erected and readily usedO
The carton according to the present invention finds special application in the packaging of heavier quantities of materials such as laundry detergents, dog food and pulverulent material. The structure is such that i~ can be stacked, readily adapted for transport by re-arran~ing the closure and carrying structure, and ultimately removing the closure structure to obtain access to the contents of ; the carton.
According to the present invention, the carton is formed from a cut and scored blank of paperboard or the like. It~comprises a tube of rectangular cross-section with opposed side and end panels. Suitable closure flaps are provided at one end of the panels in the normal way, to provide a bottom closure. The closure and carrying structure at the opposite end of the panels (and of the completed carton) includes a pair of closure flaps foldably connected to one pair of panels e.g. the .side panels and a pair of handle-forming flaps foldably connected to the o~her pair of opposed panels. The handle-forming flaps can be folded into position one over the other and over the closure flaps so as to orm the closure at this end of the tube.
The handle~forming flaps have central portions wh~ch provide , ' ~he handles; these are defined by a center fold line along the flaps with the handles extending away from the fold lines towards the free edges of the flaps. Each of the handles can be erected along its proper fold line so that it faces the other handle. The handles may be glued together if desired.
A narrow band of tear-resistant material e.g. tape of the pressure-sensitive type, is desirably adhered to the exterior surface of each handle-forming flap parallel and proximate to the fold line so as to prevent the handles tearing away from the flaps. Another narrow band of tear resistant material may be adhered to the foldably connected panels and disposed below the closure and carrying structure, so that when the carton is at the place of use, the closure and carrying structure may readily be separated from the rarton panels so as to give easy access to the contents of the carton.
The present invention, then, provides a carton comprising: ;-a) opposed front and back walls joined by opposed side walls;
b) a bottom and top wall between the front and back walls, the tDp wall including at leæt two overlapping flaps, one of the flaps being hingedly connected to the frDnt wall and the other being hin~edly connected to the back wall; and c) a handle element cut in each flap, each handle element including:
outer edges formed by spaced lines cut in the flap extending inwardly from its top edge; score line 3Q hinges extending towards each other from an end of each of the outer edges generally parallel to the top edge of the flap; and a central portion cut

The carton according to the present invention is denoted generally by the reference numeral 10 and is formed from a cut and scored blank 10A of paperboard or the like seen fragmentarily in Fig. 1.
Carton 10 formed from blank 10A consists of major panels 11 and minor panels 12 foldably connected to each other along score lines 13O A manufacturers flap 14 is foldable to a distal panel 11 along a score line 16, and flap 14 is joined to distal minor panel 12 to form a tube of rectanp,ular cross-section.

- 4 case, flap 19, has a tab 23a (Figs. 3, 5) which overlies the closure flaps 17 when the carton is assembled, as shown in Fig. 3. ~ri~ 24 is foldable along a fold line 26 to lie flat against handle-forming element 21 of flap 19. ~rip 24' is foldable along a similar fold line 26 through openings 23 to lie flat against grip 24, as shown in Figs. 4 and S.
Handle-forming flap 19 has its distal portions 29 adhered to closure flaps 17, and handle-forming flap 19A has its distal portions 29 adhered to ~he distal portions 2g of handle-forming flap 19. Handle-forming flap 19 is thus in underlapping relationship with respect to handle-forming flap 19A.
In forming carton 10, handle-forming element 21 of flap 1~ is folded along its score line 22 through 180 to the position seen in Fig. 3, and handle-forming element 21 of handle-forming flap 19A is adhered to handle-forMing element 21 of flap 19.

The scoring of patch 32 may extend into the paperboard for a distance less than the entire thickness of the board.

For transport of carton lO elements 21 of bo~h flaps 19 and 19A are erected to carrying position, the ~ear resistant strips 31 preventing the load in carton 10 from tearing flaps l9 and 19A.
The major and minor panels 11 and 12 may have adhered thereto a tear resistant strip 33 parallel to score line 18 and a short distance from it. After carton lO has been transported to its place of use, the entire closure and carrying structure may be removed by manipulating strip 33 in a known manner to expose ~he contents of the carton.
Handle-forming flap 19 has its distal portions 29 adhered to closure flaps 17, and handle-forming flap 19A has its distal portions 29 adhered to ~he distal portions 2g of handle-forming flap 19. Handle-forming flap 19 is thus in underlapping relationship with respect to handle-forming flap 19A.
In forming carton 10, handle-forming element 21 of flap 1~ is folded along its score line 22 through 180 to the position seen in Fig. 3, and handle-forming element 21 of handle-forming flap 19A is adhered to handle-forMing element 21 of flap 19.
