Container bottom and methods
Substantially triangular shaped container bottoms include a bottom wall with a concave surface. The container bottom can be used with a container body having an interior chamber for receiving at least one article. Exemplary embodiments include a container bottom attached to a container body wherein the container bottom includes a central surface area that is inwardly concave towards an interior chamber of the container body. Methods of loading a plurality of articles in a container are also provided.
1. A method of loading a plurality of articles in a container comprising the steps of:
a) providing a container having a body and defining an interior chamber, the container comprising a bottom wall including an inner surface, wherein the bottom wall is substantially inwardly concave towards the interior chamber, and wherein the container and the bottom wall are integral;
b) providing a stack of articles comprising snack pieces having a spherically convex surface;
c) inserting the stack of articles at least partially into the interior chamber until a surface portion of the leading article of the stack of articles contacts the inner surface of the bottom wall with an Angle Between Tangents of less than or equal to about 45°, wherein the Angle Between Tangents comprises the angle between a tangent line of a curved surface of the leading article at the initial contact point between the leading article and the inner surface and a tangent line of the inner surface at the initial contact point; and
d) reorienting the leading article by forcing the leading article against the inner surface such that the convex surface of the article cooperates with the inner surface so that the article is in a properly aligned stacked position such that it conforms to the inwardly concave bottom wall.
2. The method of claim 1 , further comprising the step of rotating the container to change the orientation of the container with respect to a vertical axis.
3. The method of claim 1 , wherein the stack of articles are inserted in a substantially horizontal direction.
4. The method of claim 1 , and
wherein the container has a radial distance between the body and a central axis that is perpendicular to the planar projected foot print of the container and through the center of gravity of the surface; and
wherein the bottom wall of the container comprises a central surface area, the central surface area having points along its perimeter that extend less than about 85% of the maximum radial distance between the container body and a geometric central axis.
5. The method of claim 1 , wherein the inner surface is concave towards the interior chamber.
