Molded plastic container
A container is disclosed having a top rim, a sidewall, and a bottom panel, wherein the sidewall extends at least from the top rim to the bottom panel, the top rim is generally circular, the bottom panel is generally rectangular, and the sidewall transitions from a circular portion adjacent to the top rim to a generally rectangular portion adjacent to the bottom panel.
1. A molded plastic container including a circular top opening
said circular top opening having a circular top rim with a first radius R;
a generally flat bottom panel parallel to and spaced from the circular top opening;
a unitary side panel having a height H, a top boundary and a bottom boundary; said height H comprising the distance along a perpendicular axis between the bottom panel and the center of the circular top rim; said container formed with first and second planes of symmetry at right angles and intersecting each other along the perpendicular axis
said bottom panel having a boundary including first and second pairs of opposite sides, each adjacent side joined by an arcuate section having an equal radius R 3 at the midpoint thereof, said first pair of opposite sides of said bottom panel comprising generally straight, parallel; spaced lines and each said second pair of opposite sides comprising an arc having the same radius at the midpoint thereof R 2 , said planes of symmetry intersecting the perpendicular axis and the line joining the median of the opposed straight lines of the first pair of sides of the bottom panel and the perpendicular axis and line joining median of the opposed arcuate sides of second pair of sides of the bottom panel;
said side panel comprising a truncated cone formed by panel sections, each said panel section comprising a shaped curved panel section with a generally circular segment top boundary and a bottom boundary coincident with a distinct side of the bottom panel, said opposite panel sections comprising mirror images of each other and symmetrical with respect to both the first and second planes of symmetry; wherein R 3 <R<R 2 ; and wherein said bottom panel defines rays respectively extending from each point on the boundary, through said perpendicular axis, to an opposed point on the boundary, wherein the length of each said ray is less than 2R.
2. The container of claim 1 wherein the rim is generally a flat, coplanar rim perpendicular to the perpendicular axis and extending radially outwardly from the generally circular opening at the top boundary of the side panel.
3. The container of claim 1 wherein the side panel includes an outside surface and further including an in-mold label on the outside surface of the side panel.
4. The container of claim 1 wherein the ratio of R to R 2 is from 0.65 to 0.85.
5. The container of claim 1 wherein the ratio of R to R 2 is from 0.7 to 0.8.
6. The container of claim 1 wherein the ratio of R 3 to R is from 0.25 to 0.34.
7. The container of claim 1 wherein the ratio of R 3 to R is from 0.26 to 0.32.
8. The container of claim 1 wherein the ratio of R to R 2 is from 0.65 to 0.85 and the ratio of R 3 to R is from 0.25 to 0.34.
9. The container of claim 1 wherein the ratio of R to R 2 is from 0.7 to 0.8 and the ratio of R 3 to R is from 0.26 to 0.32.
