Container and method of manufacture
A method for manufacturing a food and/or beverage packaging container is provided. The method includes injection molding a preform using a two phase injection system. A first phase of the two phase injection system includes injecting a first material into the preform and a second phase of the two phase injection system includes injecting a second material into the preform. The method further includes disposing the preform in a mold, blow molding the preform into an intermediate article having a length, a diameter and side walls having a wall thickness, and trimming the intermediate article to form a finished container having a wide mouth neck. Systems and finished products are disclosed.

blow molding the preform into an intermediate article; and
trimming the intermediate article to form the finished container and the scrap material, the finished container comprising the first material and the scrap material comprising the second material, the scrap material being free of the first material.
2. The finished container and scrap material recited in claim 1 , wherein injection molding the preform comprises using a two phase injection system, a first phase of the two phase injection system comprises injecting the first material into the preform and a second phase of the two phase injection system comprises injecting the second material into the preform.
3. The container and scrap material recited in claim 1 , wherein the finished container is free of the second material.
4. The container and scrap material recited in claim 1 , wherein the finished container has a wide mouth neck.
5. The container and scrap material recited in claim 1 , wherein the first material comprises virgin polyethylene terephythalate (PET) and the second material comprises PET and at least one additive.
6. The container and scrap material recited in claim 5 , wherein the at least one additive comprises at least one of a group consisting of passive oxygen scavengers, active oxygen scavengers, colorants, calcium carbonate fillers and foaming agents.
7. The container and scrap material recited in claim 1 , wherein the first material consists of polyethylene terephythalate (PET) and the second material comprises PET and at least one additive.
8. The container and scrap material recited in claim 7 , wherein the at least one additive comprises at least one of a group consisting of passive oxygen scavengers, active oxygen scavengers, colorants, calcium carbonate fillers and foaming agents.
9. A first finished container and a second finished container made by a process comprising the steps of:
injection molding a first preform comprising a first material and a second material;
disposing the first preform in a mold;
blow molding the first preform into a first intermediate article;
trimming the first intermediate article to form the first finished container and produce scrap material, the first finished container comprising the first material and the scrap material comprising the second material, the scrap material being free of the first material;
injecting the scrap material into a second preform;
disposing the second preform in a mold;
blow molding the second preform into a second intermediate article; and
trimming the second intermediate article to form the second finished container.
10. The first finished container and the second finished container recited in claim 9 , wherein injection molding the first preform comprises using a two phase injection system, wherein a first phase of the two phase injection system comprises injecting the first material into the first preform and a second phase of the two phase injection system comprises injecting the second material into the first preform.
11. The first finished container and the second finished container recited in claim 9 , wherein the first finished container has a wide mouth neck.
12. The first finished container and the second finished container recited in claim 9 , wherein the first material is virgin polyethylene terephythalate (PET) and the second material comprises PET and at least one additive.
13. The first finished container and the second finished container recited in claim 12 , wherein the at least one additive comprises at least one of a group consisting of passive oxygen scavengers, active oxygen scavengers, colorants, calcium carbonate fillers and foaming agents.
14. The first finished container and the second finished container recited in claim 9 , wherein the first material consists of polyethylene terephythalate (PET) and the second material comprises PET and at least one additive.
15. The first finished container and the second finished container recited in claim 14 , wherein the at least one additive comprises at least one of a group consisting of passive oxygen scavengers, active oxygen scavengers, colorants, calcium carbonate fillers and foaming agents.
16. A first finished container and a second finished container made by a process comprising the steps of:
injection molding a first preform comprising a first material and a second material;
disposing the first preform in a mold;
blow molding the first preform into a first intermediate article;
trimming the first intermediate article to form the first finished container and produce scrap material;
injecting the scrap material into a second preform;
disposing the second preform in a mold;
blow molding the second preform into a second intermediate article;
trimming the second intermediate article to form the second finished container, wherein the first finished container comprises the first material, the scrap material comprising the second material, the scrap material being free of the first material, the first finished container being free of the second material.
17. The first finished container and the second finished container recited in claim 16 , wherein injection molding the first preform comprises using a two phase injection system, wherein a first phase of the two phase injection system comprises injecting the first material into the first preform and a second phase of the two phase injection system comprises injecting the second material into the first preform.
18. The first finished container and the second finished container recited in claim 16 , wherein:
the first material consists of polyethylene terephythalate (PET) and the second material comprises PET and at least one additive; and
the at least one additive comprises at least one of a group consisting of passive oxygen scavengers, active oxygen scavengers, colorants, calcium carbonate fillers and foaming agents.
