Abstract
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.
Claims18
A finished container and scrap material made by a process comprising the steps of:
- injection molding a preform comprising a first material and a second material;
- disposing the preform in a mold;
- 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.
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.
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.
