BACKGROUND OF THE INVENTION
This invention relates generally to containers constructed from blanks of sheet material and, more particularly, to apparatus and methods for constructing the containers.
Containers are often used to store, display and/or dispense products, such as confectionary products, bulk products, food condiments or other products. The container is usually filled with the product and closed for transportation to a home, restaurant or retail store. At least some known containers are difficult and time-consuming to manufacture. Accordingly, such containers are costly to manufacture and require human attention in the forming of the container, as well as a more sophisticated forming machine. Moreover, because of the increased costs, at least some containers are simply designed in an effort to reduce costs, manufacturing time and labor, which oftentimes results in reduced functionality of the container.

In this embodiment, as rotary head 1023 rotates between the initial configuration at about 0° to the final configuration at about 360°, an interior surface of intermediate side panels 342, 346 and 350 contacts a corresponding exterior surface 1142, 1146 and 1150 of rotary head 1023, as shown in FIGS. 27-30. In an alternative embodiment, intermediate side panels 342, 346 and/or 350 may not necessarily contact corresponding exterior surface 1142, 1146 and 1150 as blank 330 is wrapped about rotary head 1023.
In one embodiment, with blank 330 wrapped around rotary head 1023 in a final configuration as shown in FIG. 30, intermediate side panel 354 is folded along fold line 372 such that an interior surface of intermediate side panel 354 contacts a corresponding exterior surface 1154 of rotary head 1023. Further, side panel 356 is folded along fold line 374 to contact an exterior surface of side panel 340. The interior surface of side panel 356 is adhesively coupled using a suitable adhesive material to the exterior surface of side panel 340 at manufacturing joint 541 to form side walls 540, 544, 548 and 552 and intermediate side walls 542, 546, 550 and 554 of container 500.

Before or during the rotation of rotary head 1023 to the 450° configuration, an adhesive material is applied to the interior surface of side panel 356 and/or the exterior surface of side panel 340. In the 450° configuration, the adhesive material is compressed between side panel 340 and side panel 356 to adhesively couple side panel 340 and side panel 356.
Bottom 570 is then formed or constructing by folding first bottom flap 384 and fifth bottom flap 452 against rotary head 1023 along respective fold line 386 and 454 such that first bottom flap 384 and fifth bottom flap 452 are oriented generally perpendicular to side wall 540 of container 500. Similarly, third bottom flap 418 is folded against rotary head 1023 along fold line 420 such that third bottom flap 418 is oriented generally perpendicular to side wall 548 of container 500. Second bottom flap 398 is then folded against first bottom flap 384 and/or fifth bottom flap 452 and opposing third bottom flap 418 and adhesively coupled to first bottom flap 384, third bottom flap 418 and/or fifth bottom flap 452. Fourth bottom flap 432 is folded against first bottom flap 384 and/or fifth bottom flap 452 and opposing third bottom flap 418 and adhesively coupled to first bottom flap 384, third bottom flap 418 and/or fifth bottom flap 452.
