Lemon, North Vancouver, British Columbia, Canada, assignor, by mesne assignments, to Unipalr Overseas Ltd, Vancouver, British Columbia, Canada Filed Mar. 5, 1962, 'Ser. No. 177,274 Claims priority, application Canada Dec. 6, 1951 2 Claims. (til. 220-405) This invention relates to cartons of the type incorporating an extensible handle.

It is known to form open-topped cartons or carriers from a one-piece blank whereby mutually cooperating longitudinal and transverse partitions, secured to the wall structure of the carton, are provided so as to divide the interior of the carton into a pair of adjacent rows of article receiving compartments. Moreover, it is also known to provide such a type carton with an extensible carrying handle which directly cooperates with the longitudinal partition so as to limit the amount of upward movement of said handle member. However, due to the choice of designs of such cartons, each end of each row of compartments has been provided with an end wall panel, making a total of four such panels, and this has considerably added to the production and assembly costs. Moreover, and with these types of designs of cartons, it has been impossible integrally to connect the lower edge of each end wall panel with the adjacent end edge of the bottom thereby giving greater rigidity to the entire wall structure of the carton.

This disadvantage was then overcome by United States Patent No. Re. 24,789 which provided a carton having a top closure integral with a wall structure, with an interior assembly of mutually transverse partitions, defining a plurality of article receiving compartments, wherein one of the partitions includes a handle portion and is movable between a first retracted position in which the handle portion lies beneath the top closure and a second 0 erative position where the handle portion projects above the wall structure, and wherein at least one other of the partitions limits the amount of movement of the handle partition member. However, in the specific form of the invention illustrated in the aforesaid United States Patent No. Re. 24,789, seven components were required to form the carton, i.e. a blank for forming the wall structure, a blank for forming the combined handle member and longitudinal partition, and five blanks for forming the transverse partition members. Moreover, the five transverse partitions required individual positioning with respect to the handle member and the wall structure when forming a knockdown carton.

Accordingly, it is the object of the present invention to reduce the positioning of the components forming the interior assembly to a minimum.

According to one aspect, the present invention relates to a carton of the type having a wall structure including a pair of mutually opposed side walls each having a pair of vertical edges, 21 pair of mutually opposed end walls each having a pair of vertical edges; each of said latter edges being connected to an associated one of said vertical edges of said side panels; and a bottom; said carton including an interior assembly defining article receiving cornpartments within said carton, said assembly including at least a pair of mutually transverse partition members a selected one of which includes a handle portion, said selected partition member being movable between a first retracted position in which said handle portion is located within said wall structure and a second operative position in which said handle portion projects above said wall structure, the other of said partition members being normal to said selected partition member and being integrally and hingedly connected, at each end thereof, to an adice jacent wall of a selected said pair thereof and cooperating with said selected partition member to limit the amount of movement of said handle portion outward of said wall structure; said partition members cooperating with one another to form a pair of adjacent rows of article receiving compartments.

According to another aspect, the present invention relates to a carton of the type having a wall structure including a pair of mutually opposed side walls each having a pair of vertical edges, a pair of mutually opposed end walls each having a pair of vertical edges; each of said latter edges being connected to an associated one of said vertical edges of said side panels; and a bottom; said carton including a top closure integral with said wall structure and an interior assembly defining article receiving compartments within said carton, said assembly including at least a pair of mutually transverse partition members a selected one of which includes a handle portion, said selected partition member being movable between a first retracted position in which said handle portion is located beneath said top closure and a second operative position in which said handle portion projects above said top closure, the other of said partition members being normal to said selected partition member and being integrally and hingedly connected, at each end thereof, to an adjacent wall of a selected said pair thereof and cooperating with said selected partition member to limit the amount of movement of said handle portion outward of said wall structure and above said top closure; said partition members cooperating with one another to form a pair of adjacent rows of article receiving compartments.

The invention is illustrated in the accompanying drawings in which:

FIGURE 1 is a plan view of a one-piece blank adapted to form the wall structure and integral partitions of a carton having a first type of interior assembly;

FIGURE 2 is a plan view of a one-piece blank adapted to form the handle member of the type of carton formed by the blank of FIGURE 1;

FIGURE 3 is a plan view of the combined blanks showing one stage in the assembly of the carton;

FIGURE 4 is a sectional elevation of the carton showing the handle member in its first retracted position;

FIGURE 5 is a view similar to FIGURE 4 but showing the handle member in its second operative position;

FIGURE 6 is a perspective View of the first type of carton;

FIGURE 7 is a view similar to FIGURE 1 but showing a one-piece blank adapted to form a carton having a second type of interior assembly;

FIGURE 8 is a similar view to FIGURE 5 but showing the second type of interior assembly; and

FIGURE 9 is a similar view to FIGURE 6 but showing the second type of interior assembly.

Referring to the drawings, and in particular to FIGURE 1, it will be seen that a first one-piece blank of resilient material is cut and scored to provide a plurality of portions comprising a pair of side wall primary panels 1, 2 and a pair of end wall primary panels 3, 4, side wall panel 2 being provided with a hingeable tab 5 integrally connected thereto along a common score line 6, the obverse face (not shown) of said tab 5 being coated with pressure sensitive adhesive, preferably employed throughout the construction of the carton, as is a strip 7 of end wall panel 4.

Each of the side wall panels 1, 2 is provided with a top closure side flap 8 preferably recessed at 9 and provided with a hingeable finger tab it as well as with a bottom closure side flap 11. Each of the end wall panels 3, 4 is provided with a top closure end flap 12 and a bottom closure end flap 13.

As will be seen from FIGURE 1, side wall panel 1 is scored and incised to provide a plurality of arcuate secondary panels indicated generally at 14, each integrally and hingedly connected to said side wall panel 1 by means of score lines 15, the Width w of each of said panels 14 being substantially equal to half of the required width of said carton. Moreover, the depth d of one end of each of said panels 14 is greater than the depth d of the remaining end thereof.

Side wall panel 2 is also provided with a corresponding plurality of arcuate secondary panels 16 each integrally and hingedly connected to said side wall panel 2 by means of score lines 17. However, the arcuate panels 16 differ from the arcuate panels 14 in that they are each provided with a projecting tongue 18 on one end thereof, one face of each of said tongues being coated with pressure sensitive adhesive as is a corresponding area 19 on each of the arcuate panels 14.

It will be noted that the depth d of one end of each of the arcuate secondary panels 16 is the same as the depth d of arcuate panels 14 and that the depth d of the tongues 18 is the same as the depth d of the arcuate panels 14. However, it will be observed that the width w of each of the arcuate panels 16 is greater than the width w of the arcuate panels 14 and, hence, is greater than half of the required width of the carton.

The second one-piece blank shown in FIGURE 2 is adapted to form the combined handle and partition member and has a main body portion 20 having a reduced carrying portion 21 having a hand-hole 22. A common score line 23 connects the reduced carrying portion 21 with a strengthening panel 24 also provided with a handhole 25 corresponding to hand-hole 22, and a score line 26 integrally connects a pair of sub-panels 27 to the main body portion 20. As will be seen from reference to FIG- URE 2, the upper side of strengthening panel 24, the reduced carrying portion 21, the sub-panels 27 and a portion of the main body 20 corresponding to the depth of each sub-panel 27, is coated with pressure sensitive adhesive. The main body portion 20 is provided with a plurality of vertical slots 28 each of a depth less than the depth d and greater than the depth d respectively, of the arcuate panels 14 and 16.

Accordingly, to form the combined handle and partition member, it is merely necessary to fold the strengthening panel 24 along score line 23 so that its coated surface is in registry with the coated surface of the reduced carrying portion 21, and to fold the sub-panels 27 along the score lines 26 so that the coated surface thereof is brought into registry with the coated portion of the main body 20. Pressure is then applied to the blank to bring about adhesion between the components.

In forming a knock-down carton, the onepiece blank shown in FIGURE 1 and described above, is positioned as is shown in FIGURE 3 with the free ends of the arcuate panel members 14 slightly elevated from the horizontal plane of the side wall panel 1. The combined handle and partition member is then placed over the arcuate panel members 14 so that the free end of each of the latter will project through an associated one of the vertical slots 28 with the coated surface 19 of each of said free ends facing upwardly.

The side wall panel 2 is then folded along common score line 29 so that it will partially overlie side wall panel 1 as well as entirely overlie end wall panel 3. It will be appreciated, although it has not been illustrated, that in the latter position, the coated surface of each tongue 18 of the arcuate panel members 16 will overlie and be in registry with the coated portions 19 of the arcuate panel members 14. Finally, end wall portion 4 is folded along the common score line 30, integrally and hingedly connecting said end wall panel 4 with the adjacent side wall panel 1, whereby the coated strip 7 on the end wall panel 4 will be brought into registry with the coated surface of the tab 5. Pressure is then brought to bear to bring about adhesion between the components.

To assemble a carton for filling purposes, a knock-down carton is erected and the bottom closure flaps 11, 13 closed and sealed with glue, tape, or by means of staples, in known manner.

After the carton has been filled with the desired contents, the top closure flaps 8, 12 are folded down and sealed in a similar manner to that described above in connection with the bottom closure.

When the carton is erected, due to the adhesion existing between each arcuate panel member 14 with the opposite arcuate panel member 16, said panel members will, respectively, hinge about the score lines 15 and 17 and will thus swing inwardly from and normal to their associated and respective side wall panels 1, 2. Thus, each adhesively secured pair of arcuate panel members 14, 16 will form a transverse partition extending from one side wall of the carton to the other, and the mid-portion, formed by the inner terminal end of the coated area 19 of panel 14 and the juncture of the tongue 18 with the remainder of panel 16, will be substantially located in an associated slot 28 in the combined handle and partition member, as is shown in FIGURE 4, with the upper edge of said slot in contact with and supported by said mid-portion.

Thus, the combined handle and partition member will extend substantially along the central longitudinal axis of the carton so that the main body portion 29 will serve as a longitudinal partition, located in a first retracted position in which the handle portion will be located within the wall structure constituted by the side walls, end walls and bottom, and beneath the top closure.

To carry a filled carton with the top closure undisturbed, it is merely necessary to bend the finger tabs 10 inwardly, grasp the upper edge of the handle portion which is located immediately below the recess 9, and pull upwardly. Thus, the combined handle and longitudinal partition Will move upwardly and assume a second operative position where the handle portion projects above the wall structure and the top closure for carrying purposes. As will be seen from reference to FIGURES 5 and 6, further outward or upward movement of the combined handle member and partition is prevented due to the bottom of the slots 28 contacting the underside of the mid-portion of each transverse partition.

As will be seen from FIGURES 4 to 6, due to the choice of design, the arcuate panel members 14 and 16 will, respectively, each provide an upper portion 14a and 16a and a lower portion 14b and 16b so as to provide protection between similar portions of articles in adjacent compartments of the same row thereof.

Turning now to FIGURES 7 to 9, an alternative embodiment of the invention is shown and, insofar as possible, similar reference numerals to those employed in connection with the first embodiment of the invention shown in FIGURES 1 to 6.

In the one-piece blank shown in FIGURE 7, the side wall panel 1 is cut and scored to provide a plurality of substantially rectangular panel members 14 and side wall panel 2 is similarly treated to provide a plurality of similarly shaped panel members 16 each provided with a projecting tongue 18 on its free end. As in the case of the first embodiment, the depth d of one end of each panel 14, 16 is greater than the depth d of the opposite or free end thereof.

The width w of each of the panels 14 is substantially equal to half of the required width of the carton whereas the overall width w of each of the panels 16 is greater than half of the required width of the carton.

The assembling of a knock-down carton of the second embodiment of the invention is identical to that described above in connection with FIGURES 1 to 6. In other words, a combined handle and partition member similar to that shown in FIGURE 2, is placed downwardly upon the left-hand half of the one-piece blank shown in FIG- URE 7 with the free and slightly upturned ends of panels 14 projecting through the slots 28 in the handle member. Side wall panel 2 is then bent along score line 29 to bring the coated face of each tongue 18 of the panel members 16 into registry with the coated area 19 of an associated panel member 14. Finally, end wall panel 4 is folded along score line 30 to bring the coated strip 7 into registry with the coated face of the hingeable tab and pressure is then applied to the entire assembly to effect the necessary cohesion between the components.

When a knock-down carton is erected, as will be seen from FIGURES 8 and 9, each secured pair of panel members 14 and 16 will serve as a transverse partition integrally and hingedly connected at one end thereof to the side wall 1 by means of a score line and similarly connected, by means of a score line 17, to the remaining side wall panel 2. Moreover, as will be clearly seen from FIGURE 8, the depth of each end of each transverse partition is greater than its mid-portion and the combined handle and partition member is again limited in the amount of its upward or outward movement, due to the lower end of each slot 28 abutting the underedge of the reduced midportion of an associated transverse partition.

In either embodiment of the invention, the depth of the slots 28 in the combined handle and partition member is less than the overall depth d but is sufficient to allow said combined member the required amount of upward or outward projection. In this way, the combined handle and partition member is always maintained in substantial alignment with the central longitudinal axis of the carton thereby providing ease of filling of the carton and alignment with the recess 9 in the top closure if the latter is provided.

Although both forms of the invention have been shown as being applied to a carton having a top closure, it is obviously within the scope of the invention to omit said top closure and apply the invention to an open-topped carton.

As will be seen from FIGURES 1 and 7, each of the side walls 1, 2 will have a pair of vertical edges as will the end walls 3, 4. Each vertical edge of each end wall will thus be integrally connected to an associated one of the vertical edges of the side walls and, in each of the illustrated embodiments of the invention, the selected pair of walls to which the partition members 14, 16 are integrally connected at their outer ends, is constituted by the side walls 1, 2.

I claim:

1. A carton of the type having a wall structure including a pair of mutually opposed side walls each having a pair of vertical edges, a pair of mutually opposed end walls each having a pair of vertical edges; each of said latter edges being connected to an associated one of said vertical edges of said side panels; and a bottom; said carton including an interior assembly defining article receiving compartments within said carton, said assembly including at least a pair of mutually transverse partition members a selected one of which includes a vertical slot and handle portion, said selected partition member being movable between a first retracted position in which said handle portion is located within said wall structure and a second operative position in which said handle portion projects above said wall structure; the other of said partition members being normal to said selected partition member and being constituted by a pair of panel members each integrally and hingedly connected, at one end thereof, to an adjacent wall of a selected said pair thereof and secured together, adjacent each other end thereof, to one another in parallel face-to-face contact, each said one end of each said panel member having a depth greater than the depth of each said other end; the depth of said vertical slot being less than the overall depth of said one other partition member; said one other partition member passing through said vertical slot in said selected partition member to limit the amount of movement of said handle portion outward of said wall structure; said partition members cooperating with one another to form a pair of adjacent rows of article receiving compartments.
