Abstract

A large container made of synthetic resin, and comprising a neck and a body; the body having a substantially rectangular cross section, and including an upper body and a lower body; the upper body containing a center of gravity of the container when filled with liquid; the upper body having a waist section containing the center of gravity; the waist section having a grip, the grip being not adapted to absorb a negative pressure in the container; and at least one surface of the lower body including a vacuum panel.

Claims

1. A large container made of synthetic resin comprising:

a neck; and

a body,

the body having a substantially rectangular cross section, and including an upper body and a lower body,

the upper body having a center of gravity of the container when filled with liquid,

the upper body having a waist section having a cross-section that is symmetric about two perpendicular axes and containing the center of gravity,

the waist section having a grip, the grip being structured not to absorb a negative pressure in the container,

at least one surface of the lower body including a vacuum panel, and

the waist section having a diameter smaller than a largest diameter of the upper body.

2. The container according to claim 1, wherein

the waist section has a height equal to about 20 to 40% of a height of the upper body.

3. The container according to claim 1, wherein

the waist section has a depth of 4 to 15 mm relating to the largest diameter of the upper body.

4. The container according to claim 1, wherein

the grip has a height not greater than about 33% of a height of the upper body.

5. The container according to claim 1, wherein

the grip has a width equal to about 35 to 80% of a width of a longer side of the upper body.

6. The container according to claim 1, wherein

the grip has a depth of about 5 mm or less from a wall of the waist section.

7. The container according to claim 1, wherein

the vacuum panel has an area equal to 30.6 to 48.6% of a surface area of the lower body.

8. The container according to claim 1, wherein

the lower body has a substantially flat label section;

and

the vacuum panel has an area equal to about 39.3 to 62.4% of an area of the label section.

9. The container according to claim 1, wherein

the vacuum panel has at least one transversal rib.

10. The container according to claim 9, wherein

the transversal rib has a width not smaller than 85.0% of a width of the vacuum panel.

19. The container according to claim 1, wherein the cross section of the waist section is at least partially arcuate.

11. A large container made of synthetic resin, comprising:

a neck; and

a body,

the body having a substantially rectangular cross section, and including an upper body and a lower body,

the upper body containing a center of gravity of the container when filled with liquid,

the upper body having a rib containing the center of gravity,

the rib being structured not to absorb a negative pressure in the container and being structured to surround the container, and

at least one surface of the lower body including a vacuum panel.

12. The container according to claim 11, wherein

the rib operates as a grip.

13. The container according to claim 11, wherein

the rib has a height equal to about 2 to 10% of a height of the upper body.

14. The container according to claim 11, wherein

the rib has a depth of 2 to 5 mm relating to the largest diameter of the upper body.

15. The container according to claim 11, wherein

the vacuum panel has an area equal to 23.3 to 42.0% of a surface area of the lower body.

16. The container according to claim 11, wherein

the lower body has a substantially flat label section;

and

the vacuum panel has an area equal to about 31.3 to 56.2% of an area of the label section.

17. The container according to claim 11, wherein

the vacuum panel has at least one transversal rib.

18. The container according to claim 17, wherein

the transversal rib has a width not smaller than 85.0% of a width of the vacuum panel.

20. The container according to claim 11, wherein the cross section of the rib is symmetric about two perpendicular axes and is at least partially arcuate.
