Abstract

A container for stacked food products, such as potato chips, is provided. The container includes composite laminate that includes one or more layers of cardboard. The container has a non-circular shape. The container has a horizontal cross-section with end portions that have a constant radius along their length and side portions that have a changing radius along their length wherein the end portions and the side portions transition between each other continuously.

First claim

The invention claimed is:

1. A container for storing stacked food products, comprising:
a composite body formed into an elongate enclosure between an open top end and a bottom end, the composite body including a plurality of layers that are fixed together, the composite body extending between the open top and bottom end with a consistent cross-section;
the composite body includes a helical seam that extends between the open top end and the bottom end, the helical seam fixes elongate portions of the plurality of layers together,
a closed bottom is fixed to the bottom end of the composite body, the closed bottom comprises a cardboard portion that extends across the bottom end of the composite body,
the composite body includes an inner liner layer, a first body layer, a second body layer, and an outer layer, a first adhesive is provided to affix the inner liner layer to the first body layer, and a second adhesive is provided to affix the second body layer to the outer layer;
the inner layer comprises one of PE or PET;
the first and second body layers comprise cardboard;
the outer layer comprises paper;
the composite body comprises a constant horizontal cross-section along its length, wherein the horizontal cross-section includes opposite first and second end portions and opposite first and second side portions, wherein each of the first and second end portions are arcuate and each of the first and second side portions are arcuate,
wherein the first and second side portions each extend between first and second ends and the first and second end portions each extend between first and second ends, wherein the first side portion extends from the first end of the second end portion and the second end of the first end portion and the second side portion extends from the second end of the second end portion and the first end of the first end portion;
wherein the first end portion has a constant radius about a first focus point and the second end portion has a constant radius about a second focus point, wherein the first and second focus point are both disposed upon a line that extends through a geometric center of the horizontal cross-section of the container,
wherein each of the first and second side portions have a changing radius along its length extending from a minimum at each of the first and second ends thereof to a maximum at a center thereof,
wherein transitions between the adjacent ends of the various end and side portions are continuous.

2. The container of claim 1 , wherein each of the first and second side portions have the same geometry.

3. The container of claim 2 , wherein each of the first and second end portions have the same geometry.

4. The container of claim 1 , wherein the first and second end portions have a constant radius of 27 mm.

5. The container of claim 4 , wherein the first and second focus points are each about 10.5 mm from the geometric center horizontal cross-section.

6. The container of claim 5 , wherein the horizontal cross-section is about 75 mm long and about 56.8 mm wide.

7. The container of claim 1 , wherein the line that extends through the first and second focus points and the geometric center of the horizontal cross-section establishes a mirror plane on opposite sides of the line.

8. The container of claim 7 , further comprising a second line that extends through the geometric center and is perpendicular to the line, wherein the second line establishes a mirror plane on opposite sides of the second line.

9. The container of claim 1 , wherein each transition between the respective first and second end portions and the respective first and second side portion includes at a position that is about 27 mm from the proximate first or second focus point and about 33.1 mm from the geometric center.

10. The container of claim 9 , wherein the distance between the center of each of the first and second side portions and the geometric center is about 28.4 mm and the radius of the curve at the center of each of the first and second side portions is about 81.7 mm.

11. The container of claim 1 , wherein an arc length of each of the first and second side portions is about 86.8 degrees.

12. The container of claim 1 , wherein the first body layer extends between opposite first and second edges, and the second body layer extends between opposite first and second edges, wherein the first edge of the first body layer extends outward past the first edge of the second body layer, and wherein the second edge of the second body layer extends outward past the second edge of the first body layer,
wherein the helical seam is formed with the first edge of the first body layer being overlapped with the second edge of the second body layer forming an adjacent portion of the composite body.

13. A container for storing stacked food products, comprising:
a composite body formed into an elongate enclosure between an open top end and a bottom end, the composite body including a plurality of layers that are fixed together, the composite body extending between the open top and bottom end with a consistent cross-section;
the composite body includes a helical seam that extends between the open top end and the bottom end, the helical seam fixes elongate portions of the plurality of layers together,
a closed bottom is fixed to the bottom end of the composite body, the closed bottom comprises a cardboard portion that extends across the bottom end of the composite body,
the composite body includes an inner liner layer, a first body layer, a second body layer, and an outer layer, a first adhesive is provided to affix the inner liner layer to the first body layer, and a second adhesive is provided to affix the second body layer to the outer layer;
the inner layer comprises one of PE or PET;
the first and second body layers comprise cardboard;
the composite body comprises a constant horizontal cross-section along its length, wherein the horizontal cross-section includes opposite first and second end portions and opposite first and second side portions, wherein each of the first and second end portions are arcuate and each of the first and second side portions are arcuate,
wherein the first and second side portions each extend between first and second ends and the first and second end portions each extend between first and second ends, wherein the first side portion extends from the first end of the second end portion and the second end of the first end portion and the second side portion extends from the second end of the second end portion and the first end of the first end portion;
wherein the first end portion has a constant radius about a first focus point and the second end portion has a constant radius about a second focus point, wherein the first and second focus point are both disposed upon a line that extends through a geometric center of the horizontal cross-section of the container,
wherein each of the first and second side portions have a changing radius along its length extending from a minimum at each of the first and second ends thereof to a maximum at a center thereof,
wherein the transitions between the adjacent ends of the various end and side portions are continuous,
wherein each transition between the respective first and second end portions and the respective first and second side portion includes at a position that is 27 mm from the proximate first or second focus point and 33.1 mm from the geometric center, and wherein the first and second end portions have a constant radius of 27 mm, and
wherein an arc length of each of the first and second side portions is 86.8 degrees.
