Abstract

A thin-walled easily opened container and method of making the same for commercial food products that includes congruent mating and overlapping sections crimped over a cover panel.

Description

RELATED APPLICATION

The container 10 is utilized for home baking in the same manner as commerically and has the additional advantage that may be collectively stacked with others and packaged for display.

Another form of the present container is illustrated at 50 in FIGS. 8 to 11 and container 50 is seen to be substantially identical to container 10 illustrated in FIGS. 1 to 8 and generally includes a main container section 51 and an end container section 52. Container section 51 includes bottom wall 53, side walls 54 and 55 and end wall 56, while container section 52 includes side wall portions 58 and 59 and end wall portion 60. Container sections 51 and 52 are substantially identical to corresponding container sections 18 and 22 in FIGS. 1 to 8 embodiment except for the addition of a rib 61 in container section 51 and a complementary rib 61 in container section 58. As seen in FIGS. 10 and 11 the ribs 61 and 62 extend across the side walls and bottom wall of each section 51 and 52 and each have uniform wall thickness equal to the remaining portions of the sections and are arcuate in cross-section as seen clearly in FIG. 10 throughout their lengths. The ribs 61 and 61 firmly engage one another to provide additional structural strength for the container 50 and assist in holding the container sections 51 and 52 in position.

As seen in FIG. 12, an apparatus is provided for constructing either the container shown in FIGS. 1 to 8 or the one illustrated in FIGS. 9 to 11 and such apparatus generally includes a first web feeding device 70 and a second web feeding device 71 that feed thin walled aluminum webs 73 and 74 into engagement between press rollers 76 and 77. Webs 73 and 74 are laterally offset so that the webs overlap only at an area equal to area 36 in FIG. 6. One or both of the webs 73 and 74 are pre-glued with a suitable contact cement in selected areas so that only the bottom 11 carries adhesive so that when pressed together by rollers 76 and 77, they adhere to one another across area 36. Feed rollers 79 and 80 pass the composite web 73-74 to rotary draw-forming die cylinders 82 and 83 that carry respectively male and female drawing dies for forming the entire container 10 or 50 illustrated in FIGS. 4 and 8 respectively in the configuration shown in those views including side walls, cover shoulders and vertical wall lips.

After the bakery goods are inserted into the completed containers and baked, the cover panel 38 is placed on the supporting shoulders and the crimp of the upper lip is formed as shown in FIGS. 7 and 11 over the cover 38 with a suitable crimping tool.

A thin-walled container for commercial food products constructed in two sections to facilitate removal of its contents, comprising: a first section constructed of a flexible sheet having a bottom wall and at least one side wall, and a second section constructed of the same flexible sheet having a bottom wall and at least one side wall overlapping and engaging the bottom wall and side wall of the first section, said first and second sections having a wall thickness of less than 0.030 inches, said first and second sections being connected together without any separate fasteners, said side walls of the first and second sections having coplanar shoulders formed at the upper portion thereof adapted to receive a cover and having coplanar vertical shoulders at the upper portions thereof adapted to be crimped over the cover.

5. A thin-walled container for commercial food products constructed in two sections to facilitate removal of its contents, comprising: a first section constructed of a flexible sheet having a bottom wall and at least one side wall, and a second section constructed of the same flexible sheet having a bottom wall and at least one side wall overlapping and engaging the bottom wall and side wall of the first section, said first and second sections having a wall thickness of less than 0.030 inches, said first and second sections being connected together with an adhesive without any separate fasteners, said side walls of the first and second sections having a lip crimped over one another.
