Plastic container with anti-bulge panel
View Patent ↗A plastic container includes a finish portion defining an opening and a main body portion having a shape that is substantially polygonal in transverse cross-section. The main body portion has a maximum lateral dimension. At least one of the side panels includes a substantially flat portion for receiving a label and a concave portion having an average radius. A ratio of the average radius to the maximum lateral dimension is substantially within a range of about 1.0 to about 2.0. The side panel having the concave portion further has an inwardmost portion and an outwardmost portion, with a first maximum lateral distance being defined between the inwardmost portion and the outwardmost portion. A second maximum lateral distance is defined between the inwardmost portion and one of the substantially flat portions. A ratio of the first distance to the second distance is substantially within a range of about 0.8 to about 1.2.
1. A plastic container, comprising:
a finish portion defining an opening; and
a main body portion having a shape that is substantially polygonal in plan view with a plurality of side panels, the main body portion having a maximum lateral dimension between a front side panel and a rear side panel, and wherein at least one of the side panels includes a substantially flat portion for receiving a label and an outwardly-facing concave portion defined by an average radius in plan view, and further wherein a ratio of the average radius to the maximum lateral dimension is substantially within a range of about 1.0 to about 2.0.
2. A plastic container according to claim 1 , wherein the ratio of the average radius to the maximum lateral dimension is substantially within a range of about 1.1 to about 1.9.
3. A plastic container according to claim 2 , wherein the ratio of the average radius to the maximum lateral dimension is substantially within a range of that 1.2 to about 1.8.
4. A plastic container according to claim 1 , wherein the main body portion is substantially rectangular in plan view, and wherein a second of the side panels has a substantially flat portion for receiving a label and a concave portion defined by an average radius in plan view.
5. A plastic container according to claim 1 , wherein the substantially flat portion of the at least one of the side panels has a first substantially flat portion near an upper end of the panel for receiving a label and a second substantially flat portion near a lower end of the panel for receiving the label.
6. A plastic container according to claim 1 , wherein a reinforcing rib is defined in the side panel between the substantially flat portion and the concave portion.
7. A plastic container according to claim 6 , wherein the reinforcing rib has a substantially horizontal orientation.
8. A plastic container according to claim 6 , wherein the reinforcing rib defines a boundary between the substantially flat portion and the concave portion.
9. A plastic container according to claim 1 , further comprising a plurality of reinforcing ribs defined in the side panel.
10. A plastic container according to claim 1 , wherein the plastic container has a volume that is at least 64 ounces.
11. A plastic container according to claim 1 , wherein the concave portion extends inwardly from the at least one side panel, the at least one side panel having an inwardmost portion and an outwardmost portion, wherein the outwardmost portion extends laterally outwardly from a central longitudinal axis to substantially the same extent as the substantially flat portion.
12. A plastic container according to claim 1 , wherein the concave portion extends inwardly from the at least one side panel, the at least one side panel having an inwardmost portion and an outwardmost portion, with a first maximum lateral distance being defined between the inwardmost portion and the outwardmost portion and a second maximum lateral distance being defined between the inwardmost portion and the substantially flat portion, and wherein a ratio of the first distance to the second distance is substantially within a range of about 0.8 to about 1.2.
13. A plastic container according to claim 12 , wherein the ratio of the first maximum lateral distance to the second maximum lateral distance is substantially within a range of about 0.9 to about 1.1.
14. A plastic container according to claim 1 , wherein the main body portion is substantially symmetric about a plane that intersects a longitudinal axis of the container.
15. A plastic container, comprising:
a finish portion defining an opening; and
a main body portion having a shape that is substantially polygonal in plan view with a plurality of side panels, the main body portion having a maximum lateral dimension between a front side panel and a rear side panel and wherein at least one of the side panels defines an outer perimeter and includes an upper substantially flat portion along a top edge of the perimeter for receiving a label, a lower substantially flat portion along a bottom edge of the perimeter for receiving a label and an outwardly-facing concave portion defined by an average radius in plan view positioned between the first and second substantially flat portions, wherein a ratio of the average radius to the maximum lateral dimension is substantially within a range of about 1.0 to about 2.0.
16. A plastic container according to claim 15 , further comprising a rib defined between the concave portion and the first upper substantially flat portion.
17. A plastic container according to claim 16 , wherein the rib has a substantially horizontal orientation.
18. A plastic container according to claim 16 , further comprising a second rib defined between the concave portion and the lower substantially flat portion.
19. A plastic container according to claim 15 , wherein the concave portion extends inwardly from the at least one side panel, the at least one side panel having an inwardmost portion and an outwardmost portion, with a first maximum lateral distance being defined between the inwardmost portion and the outwardmost portion and a second maximum lateral distance being defined between the inwardmost portion and one of the substantially flat portions, and wherein a ratio of the first distance to the second distance is substantially within a range of about 0.8 to about 1.2.
20. A plastic container according to claim 19 , wherein the ratio of the first distance to the second distance is substantially within a range of about 0.9 to about 1.1.
