Sept. 30, 1969 R. w. c. WALKER END LOADING CARTON Filed Oct. 19, 1967 III/11.010. 4:11:11: a: 7'1

INVENTOR Richard William Charles WALKER AGENT United States Patent 74,421 Int. Cl. B65d /06, 5/10, 5/16 US. Cl. 220115 Claims ABSTRACT OF THE DISCLOSURE The present invention relates to a blank and to an end loading carton formed therefrom, said carton having an integral bottom wall, a longitudinally divided top wall, a handle member formed in one portion of said top wall and tearable from said one portion and a longitudinal central partition foldably connected to said handle member and to said bottom wall.

This invention relates to containers, more particularly to end loading containers for bottled beverages and the like.

Recently, many new end loading type cartons have been devised to meet the needs of the bee-r industry which, in many parts of the country, has shifted to end loading equipment. However, there remains a need for a relatively inexpensive but strong carton adapted to be filled by such end loading equipment.

It is thus the main object of the present invention to provide an end loading carton that is inexpensive but has adequate strength.

Broadly, the present invention comprises a one-piece carton structure having a unitary panel bottom structure with a longitudinal partition glued to said bottom and integral with a panel forming at least part of the top wall of the carton. By forming the handle from the top and partition panels no extra material is required and the bottom wall being made of one integral panel provides a relatively strong carton.

Further features, objects and advantages will be evident from the following detailed description taken into conjunction with the accompanying drawings in which:

FIG. 1 is a plan view of a carton blank.

FIG. 2 is a section view along the line 22 of FIG. 1.

FIG. 3 is a cross section through an erected carton.

FIG. 4 is a perspective view of a carton constructed in accordance with the present invention illustrating the carton prior to closing of one set of end flaps and FIG. 5 is a fragmentary cross sectional view showing the handle in carrying position.

The heavy solid lines in the drawings define the edges of the blank while the dotted lines depict fold or crease lines.

As shown in FIG. 1, the blank 10 of the present invention comprises, from left to right, a first top wall 12, a first side wall 14, a bottom wall 16, a second side wall 18 and a second top wall 20, a partitioned panel 22 and a glue flap 24. The

walls

12, 14, 16 and 18 are foldably inter-connected by

fold lines

26, 28, 30 and 32. The inter-relationship between the panel 22 and the top wall will be described hereinbelow. Glue flap 24 is foldably connected to the bottom of the partition panel 22 by fold line 34.

At opposite ends of the

walls

12, 14, 16 and 18 are end closure flaps 36, 3'8, 40, 42 and 44 respectively. These end closure flaps are connected to the respective end walls via

fold lines

46 and 48.

3,469,736 Patented Sept. 30, 1969 The panel 22 is connected to a handle member 50 and thus top wall 20 via a fold line 52. The handle member 50 forms part of the top Wall 20 and is removably secured to the wall 20 by a line of weakness 54. This line of weakness 54 may be formed in any suitable manner and serves to maintain the member 50 in the plane of the wall 20 during manufacture but permits the handle member 50 to be lifted from the panel for carrying of the carton. A suitable hand hole is formed in the handle member 50 by the flap 51, which flap is defined by a line of severance 53 and a crease line 55. The flap 51 is folded inwardly to form a hand hole in the handle member 50. Panel 22 is separated from the remainder of the wall 20 by a pair of *L-shaped lines of severance 56 and 58 which define a pair of

glue tabs

60 and 62 on the top wall 20. These

glue tabs

60 and 62 are overlapped by the top wall 12 to form a manufacturers joint in the carton.

To strengthen the handle, a handle reinforcing may be formed from the body of panel 22 and folded back to overlie the handle member 50. The reinforcing flap 64 forms such a reinforcing means. This flap 64 is cut from the panel 22 via lines of severance 66 and 68 but remains foldably attached to the panel 22 by a pair of fold lines 70 and 72 joining the ends of the lines 66 and 68-. These fold lines 70 and 72 are substantially parallel to the fold line 52 between the partition panel 22 and the handle member 50. A second pair of fold lines 74 and 76 parallel to lines 70 and 72 extends across the reinforcing flaps 64. These fold lines are arranged such that the lines 70 and 72 are substantially mid-way between the fold line 52 and the second pair of fold lines 74 and 76.

Connected to opposite edges of the flap 24 and panel 22, adjacent flap 24, via crease lines 78 and 80 are a pair of tabs 82. These tabs are divided into a glueing section 84 and a folding section 86 by fold line 34. The folding section 86 is further divided by a fold line 88 extending across the section 86 at an angle preferably 45 to the fold line 34.

Before the carton is assembled reinforcing flap 64 is folded along fold lines 70 and 72 out of the plane of panel 22 and through an arc of about into face-toface contact with the handle member 50 (as shown in FIG. 2). The reinforcing fiap 64 is secured in this position by any suitable means such as glue or the like.

To assemble the carton, the blank 10 is folded along crease line 32 to place the flap 24 in face-to-face contact with the bottom panel 16. The flap 24 is glued in this position thereby securing the panel 22 mid-way across the bottom Wall 16 (i.e. on the centreline of the carton). Sections 84 of the tabs 82 are connected in faceto-face relationship with the panels 40. The

walls

12 and 14 may then be folded on to the remainder of the carton by folding along line 28 and the wall 12 glued to

tabs

60 and 62 extending from panel 20.

An erected carton, with one end closed, is shown in cross section in FIG. 3. As illustrated, the top of the carton is formed by the

walls

12 and 20 with the wall 12 overlapping and glued to the tabs 60 and '62 of panel 20 to form the manufacturers joint. The central partition member 22 is integral with the handle member 50 which in turn is detachably held Within the plane of the wall 20. The partition member 22 extends substantially perpendicular to the handle member 50 and thus the wall 20 by folding along the fold line 52. Folding along fold line 52 also causes the handle reinforcing flap to be bent at fold lines 74 and 76. The opposite end of partition 22 is secured to the bottom Wall 16 via the flap 14 and tabs 84 as described hereinabove (see FIG. 4). When the end flaps 40 are folded to closed position, as shown in FIG. 3, the fold line 88 moves outwardly to form a gusset while the tabs 82 fold along lines 78, 80

and 34 to move the two halves of section 86 (Le. the parts on opposite sides of line 88) into face-to-face relationship and the section 84 into a plane substantially perpendicular to the flap 24.

FIG. 4 illustrates the carton just prior to closing one end and showing the handle 50 in position in the plane of the top wall 20. The handle 50 and handle reinforcing 64 may be lifted from the panel 20 simply by bending the tab 51 along fold line 55 to form the hand hole 90 (see FIG. curling the fingers through the hand hole and lifting up to separate the handle member 50 from the panel 20. The handle member 50 is thus lifted in the direction of the arrow A to move same into carrying position as shown in FIG. 5.

The top walls 12 and may be provided with suitable score lines as indicated at 90 and 92 to facilitate opening of the top of the carton. If desired, these score lines may extend about the complete periphery of the top wall of the carton so that the whole top wall may be completely separated from the carton. Preferably the

lines

90 and 92 will be laterally offset to avoid the carton being accidentally opened.

It will be noted that applicant has provided an end loading carton having a strong unitary bottom Wall and has disclosed a carton manufactured from a minimum amount of board, thereby reducing the cost of the carton without sacrificing strength.
