Multiflow gassing system

1. A system for providing controlled environment gas to a lid and container, comprising:

a lid carrier;

a gas rail assembly adjacent the lid carrier, the gas rail assembly having a top portion including a top portion gas outlet and an end portion including a end portion gas outlet; and

a plate adjacent the end portion;

wherein the top portion gas outlet is oriented to direct the controlled environment gas into the lid and the end portion gas outlet is oriented to direct the controlled environment gas into a lid-container engagement region;

the plate comprises a pair of opposed plates with a channel between the pair of opposed plates; and

each plate of the pair of opposed plates includes a radiused region adjacent the end portion.

2. The system of claim 1 wherein the plate forms a Coanda device.

3. The system of claim 1 wherein a shape of the plate is selected from the group consisting of convex, concave, straight, angled, and free-form.

4. The system of claim 1 wherein the radiused region has a radius of 0.05 to 1.0 inches.

5. The system of claim 1 wherein the plate has a horizontally oriented portion and an angled portion.

6. The system of claim 1 wherein the plate has a flange portion operably attached to the gas rail assembly.

7. The system of claim 6 further comprising adjustment knobs adjustably connecting the flange portion to the gas rail assembly for positioning the pair of opposed plates relative to one of the gas rail assembly and each other.

8. The system of claim 1 wherein the gas rail assembly has a bottom portion having a bottom portion gas outlet oriented to direct the controlled environment gas into the container.

9. The system of claim 8 further comprising a conveyer positioned to move the container along the bottom portion.

10. The system of claim 8 wherein the top portion and the bottom portion are positioned at an angle.

11. The system of claim 1 wherein the gas rail assembly includes a wedge shaped plenum.

12. The system of claim 1 wherein the end portion gas outlet has a laminar screen with at least one opening therein.

13. The system of claim 1 wherein the end portion gas outlet has a gassing element selected from the group consisting of a laminar screen, a dual flow laminar screen, and a gas manifold.

14. A system for providing controlled environment gas to a lid and container, the system comprising:

means for flowing the controlled environment gas into a lid passing along a lid carrier; and

means for flowing the controlled environment gas past a plate into a lid-container engagement region;

wherein the means for flowing the controlled environment gas past a plate into a lid-container engagement region comprises means for flowing the controlled environment gas through a Venturi device into the lid-container engagement region, the Venturi device being a channel with a radiused region in the plate.

15. The system of claim 14 further comprising means for simultaneously flowing the controlled environment gas into the container.

16. The system of claim 14 further comprising means for conveying the container into the lid-container engagement region.

17. The system of claim 14 further comprising means for adjusting flow velocity through the Venturi device.

18. A system for providing controlled environment gas to a lid and container, comprising:

a lid carrier;

a gas rail assembly adjacent the lid carrier, the gas rail assembly having a top portion including a top portion gas outlet and an end portion including a end portion gas outlet; and

a plate adjacent the end portion;

wherein the top portion gas outlet is oriented to direct the controlled environment gas into the lid and the end portion gas outlet is oriented to direct the controlled environment gas into a lid-container engagement region;

the plate comprises a pair of opposed plates with a channel between the pair of opposed plates; and

the pair of opposed plates forms a Venturi device.

19. A system for providing controlled environment gas to a lid and container, comprising:

a lid carrier;

a gas rail assembly adjacent the lid carrier, the gas rail assembly having a top portion including a top portion gas outlet and an end portion including a end portion gas outlet;

a Venturi tube adjacent the end portion, the Venturi tube being a tube with a radiused region; and

wherein the top portion gas outlet is oriented to direct the controlled environment gas into the lid and the end portion gas outlet is oriented to direct the controlled environment gas into a lid-container engagement region.

20. A system for providing controlled environment gas to a lid and container, the system comprising:

means for flowing the controlled environment gas into a lid passing along a lid carrier; and

means for flowing the controlled environment gas past a plate into a lid-container engagement region;

wherein the means for flowing the controlled environment gas past a plate into a lid-container engagement region comprises means for flowing the controlled environment gas over a Coanda device into the lid-container engagement region, the Coanda device being a curved surface of the plate.
