Claims. (Cl. 93-37) This application constitutes a division of now-pending application Serial No. 221,530 filed September 5, 1962, now Patent No. 3,135,453 which is a continuation of Serial No. 115,415 filed June 7, 1961, which was aban cloned in favor of Serial No. 221,530.

This invention relates generally to partitioned or cornpartmentized containers of the character especially adapted to hold a plurality of articles or different materials; see for example U.S. Letters Patent to Miessler, Sr., #2940653, dated June 14, 1960.

A primary object of this invention is to provide a novel method utilizing a one-piece blank construction and comprising the steps for automatically orienting and posi tioning a partition panel between opposite sides of a container or carton when the container is being erected.

A further object of the present invention is to provide a novel method of assembling a carton blank to provide a container which, when erected, will incorporate a partition panel aifording adjacent compartments in the container.

Another object of the invention is to provide a novel method atfording economies in use of material, space used for storage, and a reduction of manipulative steps in the assembly of a partitioned container.

Other objects and the nature and advantages of the instant invention will be apparent from the following description taken in conjunction with the accompanying drawings, wherein:

FIG. 1 is a plan view of a blank used in the invention;

FIG. 2 is a side elevation of the novel blank;

FIG. 3 is a plan view similar to FIG. 1, showing the first step of assembly of the blank;

FIG. 4 is a side elevation of FIG. 3, illustrating the second step of assembly of the invention;

FIG. 5 is a view similar to FIG. 4 showing the next step of assembly of the blank;

FIG. 6 is a view similar to FIGS. 4 and 5 showing the next manipulative step of the blank;

FIG. 7 is a side elevation showing the last manipulative step of the blank;

FIG. 8 is a perspective view of the novel folded partitioned container, portions being broken away for the purpose of showing details; and

FIG. 9 is an end perspective view of the partitioned container erected from the condition shown in FIG. 8.

Referring to the drawings in detail, a substantially rectangular blank of paperboard material or the like is indicated generally at 11 and comprises, in order, a first rectangular end panel 12 hingedly connected by a fold line 14 to a first side panel 16 which is hingedly connected by a fold line 18 to a second end panel 26, which is hingedly connected by a fold line 22 to a second side panel 24. Hingedly connected to the upper marginal edges of the

panels

12, 16, 21) and 24, at

fold lines

26, 28, 3t) and 32, respectively, are top forming

flaps

34, 36, 38 and 40, respectively, which are separated by

cut lines

42, 44 and 46 which are in alignment with the fold lines 14, 18 and 22, respectively. Hingedly connected to the fold lines 48, 50, 52 and 54, at the bottom of the

respective panels

12, 16, 20 and 24, are bottom forming

flaps

56, 58, 60 and 62, respectively. The bottom forming flaps 56,

3,185,648 Patented May 25, 1965 58, 60 and 62, are separated by

cut lines

63, 64 and 65, which are respectively in alignment with the

fold lines

14, 18 and 22.

Hingedly connected by a fold line 66 at the side margin of the second side panel 24 is a panel including a container-glue flap 67, the

opposite ends

68 and 70 of which are tapered slightly away from the

fold lines

32 and 54 to dispose the glue flap below the upper and lower margins of the assembled container.

Hingedly connected by a line of separation or foldable tear line 72 is a first partition glue flap 74 extending the length of one margin of a rectangular partition panel 76 and being hingedly connected thereto by a fold line 78-. Hingedly connected at the opposite side margin of the partition panel 76 at a fold line 80 is a second partition glue flap 82.

The inner surface 84 of the partition glue flap 82 will have deposited thereon a layer of suitable adhesive material by means of automatic gluing apparatus; see FIG. 1. After this has been accomplished, the partition panel and partition glue flap 74 are folded along the tearable fold lines 72 into juxtaposed relation on the second side panel 24 in the manner shown in FIGS. 3 and 4. After this has been accomplished, glue is applied to the exposed sides of the container glue flap 67 and first partition glue flap 74 which are disposed in juxtaposition, as seen in FIGS. 3 and 4. The glue can be deposited, for example, by means of a conventional, lower glue pot-and-wheel 38 and an upper, glue bottle-and-wheel 86 as seen diagrammatically in FIG. 4, or any other suitable means may be utilized.

After glue has been disposed on opposite sides or outer exposed surfaces of the

glue flaps

67, 74, the panel 24, with the partition panel 7 6 attached thereto, is folded into overlying relationship with respect to the second end panel 20 disposing the glue-applied surface of the glue flap 74 onto an intermediate portion of the first side panel 16, see FIG. 5. After this has been accomplished, the first end panel 12 is folded on the hinge line 14 toward the exposed surface of the glue flap 67 of the container and the marginal edge 90 of the first end panel will be secured in overlying relationship to the container glue flap 67.

It will be noted that the

side panels

16 and 24 are of the same dimensions, and the

end panels

12 and 20 and the partition panel 76 are of an equal Width.

As seen in FIG. 6, the assembled carton is illustrated; however, the tear line 72 is not severed at this time.

The assembled position of the parts is shown in FIG. 7. When the first and

second side panels

16 and 24 are disposed in parallel relationship, and the end panels are also disposed in parallel relationship to form a rectangular container, the tear line 72 will be severed, and the partition panel 76 Will move to a parallel position with respect to the

end panels

12 and 26, see FIGS. 7 and 9. After this has been accomplished, the top and bottom flaps 34- 40 and 56-62 may be oriented into their proper position.

Thus it will be noted that through the expedient of constructing a single unitary blank of the character described, a partition panel is provided which is oriented into its proper position of assembly during the erection of the container, this expedient requiring no special manipulative steps, and merely involving a single one-piece blank rather than separate parts comprising the container per se and the partition per se.

It will be obvious to those skilled in the art that various changes may be made without departing from the spirit of the invention and therefore the invention is not limited to what is shown in the drawings and described in the specification but only as indicated in the appended claims.
