Hot-fillable blow molded container with pinch-grip vacuum panels

1. A container made of polymer materials comprising:

a neck finish portion suitable for receiving a closure;

a shoulder portion adjacent said neck finish portion;

a body portion adjacent said shoulder portion; and

a bottom portion adjacent said body portion;

said body portion including a sidewall having at least one pair of substantially diametrically apposed vacuum panels, each of said at least one pair of diametrically apposed vacuum panels having a pinch-grip portion formed therein and a flexible-field adjacent to said pinch-grip portion formed therein, said flexible-field having a plurality of indented dimples formed therein;

said pinch-grip portion having a bridge with a tongue portion extending into said flexible-field.

2. The container according to claim 1 , wherein said vacuum panels with said pinch-grip portion have an edge.

3. The container according to claim 2 , wherein said edge has an adjacent zone that generally pivots in a hinge-like action in response to an external force.

4. The container according to claim 2 , wherein said bridge has an end adjacent said edge.

5. The container according to claim 1 , wherein said flexible-field has an overall generally convex shaped surface appearance in cross section.

6. The container according to claim 5 , wherein said convex shaped surface becomes a generally overall concave shaped surface in cross section in response to an external force.

7. The container according to claim 1 , wherein said indented dimples are arranged in uniformly spaced positions forming a series of horizontal, vertical, and diagonal rows.

8. The container according to claim 7 , wherein said uniformly spaced positions of said plurality of indented dimples form a series of substantially horizontal, vertical, and diagonal flex-lines extending between said dimples.

9. The container according to claim 1 , wherein said polymer materials are substantially one of a polyester, a polypropylene, and a polyethylene.

10. The container according to claim 9 , wherein said polyester is substantially one of a polyethylene terephthalate and a polyethylene naphthalate.

11. A hot-filled polymer container filled with a liquid at an elevated temperature, sealed with a closure, and cooled thereby establishing a slight vacuum within said container, said container comprising:

a neck finish portion suitable for receiving the closure;

a shoulder portion adjacent said neck finish portion;

a body portion adjacent said shoulder portion; and

a bottom portion adjacent said body portion;

said body portion including a sidewall having at least one pair of substantially diametrically apposed vacuum panels, each of said at least one pair of diametrically apposed vacuum panels having a pinch-grip portion formed therein and a flexible-field adjacent to said pinch-grip portion formed therein, said flexible-field having a plurality of indented dimples formed therein;

said pinch-grip portion having a bridge with a tongue portion extending into said flexible field.

12. The container according to claim 11 , wherein said temperature of the liquid is between 180° F. to 205° F. (82° C. to 96° C.).

13. The container according to claim 11 , wherein said polymer is substantially one of a polyester, a polypropylene, and a polyethylene.

14. The container according to claim 13 , wherein said polyester is substantially one of a polyethylene terephthalate and a polyethylene naphthalate.

15. A stretch-molded heat-set polyester container formed within a mold cavity having a temperature of approximately 250° F. to 350° F. (121° C. to 176° C.), said container comprising:

a neck finish portion suitable for receiving a closure;

a shoulder portion adjacent said neck finish portion;

a body portion adjacent said shoulder portion;

a bottom portion adjacent said body portion;

said body portion including a sidewall having at least one pair of substantially diametrically apposed vacuum panels, each of said at least one pair of diametrically apposed vacuum panels having a pinch-grip portion formed therein and a flexible-field adjacent to said pinch-grip portion formed therein, said flexible-field having a plurality of indented dimples formed therein;

said pinch-grip portion having a bridge with a tongue portion extending into said flexible field; and

a generally biaxially oriented molecular structure.

16. The container according to claim 15 , wherein said polyester is substantially a polyethylene terephthalate.

17. The container according to claim 15 , wherein said indented dimples are arranged in uniformly spaced positions forming a series of horizontal, vertical, and diagonal rows.
