Abstract

A system and method of forming a metal container with a featured sidewall may include providing a blow molded metal container. The metal container may be positioned into a mold inclusive of at least one sidewall feature. The metal container may be blow molded again to cause the at least one sidewall feature to be created in the sidewall of the container as defined by the mold. In one embodiment, a sidewall of the metal container may be at least partially annealed. The sidewall feature may include a portion of a profile of a sporting good, such as a baseball, embossed feature (e.g., word), logo, or otherwise. The metal container may be a shaped metal container.

First claim

What is claimed:

1. A method of forming at least one molded feature in a container, said method comprising:
accessing a metal container with a sidewall;
at least partially annealing the sidewall of the metal container;
positioning the metal container into a mold inclusive of at least one mold feature; and
blow molding the metal container to cause the at least one molded feature to be created in the sidewall of the metal container as defined by the at least one mold feature in the mold.

2. The method according to claim 1 , wherein accessing the metal container includes providing a partially formed metal container.

3. The method according to claim 1 , wherein accessing the metal container includes providing a fully formed metal container.

4. The method according to claim 1 , wherein at least partially annealing the sidewall includes heating the sidewall to a temperature that causes metal grains of the sidewall to transition to a reduced stress state from an existing stress state.

5. The method according to claim 1 , wherein at least partially annealing the sidewall includes at least partially annealing a localized portion of the sidewall.

6. The method according to claim 1 , wherein positioning the metal container in the mold includes moving a plurality of mold pieces about the metal container, the mold pieces, when integrated or in contact with one another, having a profile that substantially matches a profile of the metal container with the exception of the at least one mold feature of the mold.

7. The method according to claim 1 , wherein the at least one mold feature includes a portion of a profile of a sporting good.

8. The method according to claim 1 , wherein the at least one mold feature includes an embossed feature.

9. The method according to claim 8 , wherein accessing the metal container with the sidewall comprises accessing a metal container formed by blow molding.

10. The method according to claim 1 , wherein the metal in the molded feature in the sidewall has a different hardness than metal in the sidewall surrounding the molded feature.

11. The method according to claim 1 , wherein accessing the metal container includes providing a shaped metal container in a shape of a bottle.

12. A system for forming a metal container with a featured sidewall, said system comprising:
a heater configured to at least partially anneal the featured sidewall of the metal container;
a mold inclusive of at least one mold feature, and adapted to receive a blow molded metal container with a sidewall; and
a blowing mechanism configured to blow mold the metal container again to cause the at least one mold feature to create at least one molded feature in the sidewall of the metal container.

13. The system according to claim 12 , wherein the mold is configured to accept a partially formed metal container.

14. The system according to claim 12 , wherein the mold is configured to accept a fully formed metal container.

15. The system according to claim 12 , wherein the heater is configured to at least partially anneal the sidewall to a temperature that causes metal grains of the sidewall to transition to a reduced stress state from an existing stress state.

16. The system according to claim 12 , wherein the heater is configured to heat the at least partially annealed sidewall in a localized portion of the sidewall.

17. The system according to claim 12 , wherein the mold includes a plurality of mold pieces configured to be formed about the metal container, the mold pieces, when integrated or in contact with one another, having a profile that substantially matches a profile of the metal container with the exception of the at least one mold feature of the mold.

18. The system according to claim 12 , wherein the at least one mold feature includes a portion of a profile of a sporting good.
