Abstract

Claims (25)

1. A process for conveying plastic containers along a table-top conveying system, comprising the steps of:

temporarily securing a transfer stabilizing support to a bottom portion of a formed, plastic container so that the plastic container can move along a production line using the table-top conveying system, said transfer stabilizing support having a bottom surface with an opening, a sidewall extending substantially perpendicular from said bottom surface to form an open enclosure, rib projections formed in one piece with said sidewall and extending into said open enclosure from said sidewall, substantially toward a center longitudinal axis of said open enclosure, and a ridge area concentrically spaced from said sidewall of said transfer stabilizing support, wherein said ridge area is arranged to set a presentation height of the temporarily secured container at one or more of a filling station and a capping station of the production line;

filling, at the filling station, the plastic container temporarily secured to said transfer stabilizing support with a hot product;

capping, at the capping station, the hot-filled plastic container temporarily secured to said transfer stabilizing support;

creating a vacuum in the hot-filled and capped plastic container temporarily secured to said transfer stabilizing support, said creating a vacuum including cooling the hot-filled and capped plastic container using a cooling system;

manipulating, after the vacuum has been created in the plastic container, a bottom end portion of the plastic container to counter the vacuum created in the plastic container temporarily secured to said transfer stabilizing support; and

after the plastic container has gone through said filling, capping, creating, and manipulating, removing said transfer stabilizing support from said bottom portion of the plastic container.

2. The process of claim 1 , wherein the step of temporarily securing said transfer stabilizing support to the bottom portion of the formed plastic container further includes pressing said transfer stabilizing support against a bottom end of said bottom portion of the plastic container so that bottom sides of the plastic container are gripped by the rib projections in a friction-fit manner.

3. The process of claim 2 , wherein the step of temporarily securing said transfer stabilizing support to the bottom portion of the formed plastic container further includes securely inserting a spacer in the interior of the transfer stabilizing support to form the ridge area concentrically spaced from said sidewall of said transfer stability support so that said presentation height of the plastic container at said filling and capping operations is uniform for various containers.

4. The process according to claim 1 , wherein the step of temporarily securing said transfer stabilizing support to a bottom portion of the formed plastic container further includes centering said transfer stabilizing support below the formed plastic container, and then inserting said bottom portion of the plastic container into said transfer stabilizing support so that bottom sides of the plastic container are gripped by the rib projections in a friction-fit manner.

5. The process according to claim 1 , wherein the operations of the production line further include:

palletizing a number of said plastic containers;

moving the palletized number of plastic containers to the filling station; and

de-palletizing the plastic containers onto another production line for the filling station.

6. The process according to claim 1 , wherein said temporarily securing includes temporarily securing an unstable plastic container.

7. The process according to claim 1 , wherein said temporarily securing includes temporarily securing a plastic container having a stable base.

8. The process according to claim 1 , wherein said manipulating includes movement of a mechanical means through the opening of said transfer stabilizing support to invert an outwardly projecting base portion of the plastic container.

9. The process according to claim 8 ,

wherein said manipulating includes movement of a mechanical apparatus into the opening of said transfer stabilizing support to push toward the interior of the plastic container a portion of the bottom end portion of the plastic container, and

wherein said removing includes movement of said mechanical apparatus into the opening of said transfer stabilizing support to remove said transfer stabilizing support from said bottom portion of the plastic container.

10. The process according to claim 1 , further comprising bracing, during said creating a vacuum, a sidewall portion of the plastic container using the sidewall of said transfer stabilizing support.

11. The process according to claim 10 , wherein said bracing resists deformation of the plastic container.

12. The process according to claim 1 , further comprising bracing, prior to said manipulating, a sidewall portion of the hot-filled and capped plastic container having a vacuum created therein using the sidewall of said transfer stabilizing support.

13. The process according to claim 12 , wherein said bracing resists deformation of the plastic container.

14. The process according to claim 1 , further comprising, during said manipulating, resisting deformations of the plastic container using the sidewall of said transfer stabilizing support.
