Systems, methods, and apparatuses for cooling hot-filled containers
View Patent ↗The disclosed subject matter relates to container holders configured to provide a stable support for containers held therein in order to efficiently cool the containers after a hot-fill or elevated temperature operation. The container holders can allow a fluid to pass from an inner volume of the container holder to outside the container holder through side apertures and/or an open bottom end of the container holder. Groups of containers and container holders also may be cooled. Groups of containers in container holders can be processed through the cooling operation at a speed different from a speed for holderless containers.
1. A container holder, comprising:
a cylindrical sidewall forming an inner volume, a first open end, and a second open end;
a base portion at the second open end, said base portion extending from said cylindrical sidewall into the inner volume and including a hollow cylindrical portion concentric with said cylindrical sidewall and a plurality of connecting portions coupling said hollow cylindrical portion to said cylindrical sidewall; and
a plurality of slanted protrusions formed in one piece with said cylindrical sidewall, said protrusions extending into the inner volume at acute angles from said cylindrical sidewall and being configured to space-apart from the cylindrical sidewall a container placed in the inner volume, said protrusions each including an upper portion, a bottom portion, and a horizontally-extending engagement surface formed between and spaced from the upper portion and the bottom portion with an upper vertically-configured portion defined between the horizontally-extending engagement surface and the upper portion, and a lower vertically-configured portion defined between the horizontally-extending engagement surface and the lower portion, wherein the horizontally extending engagement surface is facing the base portion and configured to prevent a container placed in the inner volume from being removed from the inner volume,
and further wherein the cylindrical sidewall includes a plurality of apertures defined therein, each said aperture being configured to allow fluid to flow from the inner volume to the outside of the cylindrical sidewall to cool the container placed in the inner volume.
2. The container holder of claim 1 , wherein each said horizontally-extending engagement surface is formed by a cut-away portion extending from the bottom portion to the engagement surface of each said protrusion, said cut-away portion being configured to prevent a container placed in the inner volume from being removed from the inner volume.
3. The container holder of claim 1 , wherein the angles of said protrusions are substantially the same for each protrusion.
4. The container holder of claim 1 , wherein a number of the plurality of protrusions is the same as a number of the plurality of apertures.
5. The container holder of claim 1 , wherein the plurality of protrusions are fins, the horizontally-extending engagement surface of each said fin formed by a cut-away portion extending from the bottom portion to the engagement surface of each said protrusion and configured to prevent a container placed in the inner volume from being removed from the inner volume.
6. The container holder of claim 1 , wherein each said aperture is elongated in a direction parallel to a longitudinal axis of said cylindrical sidewall.
7. The container holder of claim 1 , wherein said base portion is configured to allow access to a vacuum panel of a container placed in the inner volume.
8. An apparatus, comprising:
at least one sidewall forming an inner volume, a first open end, and a second open end, the at least one sidewall including at least one opening defined therein to allow fluid to transfer between the inner volume and outside the inner volume, the at least one opening located intermediate the first and second open ends;
a support structure to support a container positioned thereon, the support structure being formed integrally with the at least one sidewall at the second open end, so as to extend from the at least one sidewall into the inner volume; and
spacing members formed in one piece with the sidewall to space apart from the at least one sidewall a container placed in the inner volume, wherein each spacing member includes an upper portion, a bottom portion, and at least one horizontally-extending engagement surface formed between and spaced from the upper portion and the bottom portion with an upper vertically-configured portion defined between the horizontally-extending engagement surface and the upper portion, and a lower vertically-configured portion defined between the horizontally-extending engagement surface and the lower portion, wherein the at least one horizontally-extending engagement surface is facing the base portion and configured to prevent a container placed in the inner volume from being removed from the inner volume.
9. The apparatus of claim 8 , wherein said at least one horizontally-extending engagement surface is formed by a cut-away portion extending from the bottom portion to the engagement surface of each said spacing member, said cut-away portion being configured to prevent a container placed in the inner volume from being removed from the inner volume.
10. The apparatus of claim 8 , wherein the at least one opening is configured to allow water to flow from the inner volume to the outside of the sidewall to cool a container placed in the inner volume on the support structure.
11. The container holder of claim 1 , wherein the base portion is formed in one piece with the cylindrical sidewall.
12. The apparatus of claim 8 , wherein each said horizontally-extending engagement surface is formed by a cut-away portion extending from the bottom portion to the engagement surface of each said spacing member, said cut-away portion being configured to prevent a container placed in the inner volume from being removed from the inner volume.
13. The apparatus of claim 8 , wherein the spacing members are fins, the horizontally-extending engagement surface of each said fin formed by a cut-away portion extending from the bottom portion to the engagement surface of each said spacing member and configured to prevent a container placed in the inner volume from being removed from the inner volume.
14. The apparatus of claim 8 , wherein each said spacing member is formed by a vertically-extending protruding portion including a cut-away portion thereon to define the at least one horizontally-extending engagement surface, said horizontally-extending engagement surface being configured to prevent a container placed in the inner volume from being removed from the inner volume.
15. The container holder of claim 1 , wherein the upper portion of each said protrusion includes a sloped portion.
16. The container holder of claim 15 , wherein the sloped portion is arcuate.
17. The container holder of claim 1 , wherein each said protrusion includes a bottom edge and the horizontally-extending engagement surface is parallel to the bottom edge.
18. The apparatus of claim 8 , wherein the upper portion of each said spacing member includes a sloped portion.
19. The apparatus of claim 18 , wherein the sloped portion is arcuate.
20. The apparatus of claim 8 , wherein each said spacing member includes a bottom edge and the horizontally-extending engagement surface is parallel to the bottom edge.
