Description

TECHNICAL FIELD

The present disclosure generally relates to blow-molded containers and more particularly to plastic containers and methods for making the same for food and/or packaging, for example.

BACKGROUND

Plastic blow-molded containers are commonly used for food and/or beverage packaging products. Many food and beverage products are sold to the consuming public in blow-molded containers. These containers can be made from polyethylene terephythalate or other suitable plastic resins in a range of sizes. The empty blow-molded containers can be filled with food and/or beverage products at a fill site utilizing automated fill equipment.
For example, manufacture of such plastic blow-molded containers can include initially forming plastic resin into a preform, which may be provided by injection molding. Typically, the preform includes a mouth and a generally tubular body that terminates in a closed end. Prior to being formed into containers, preforms are softened and transferred into a mold cavity configured in the shape of a selected container. In the mold cavity, the preforms are blow-molded or stretch blow-molded and expanded into the selected container.
Plastic blow-molded containers often attempt to maximize a tradeoff between weight and strength. For example, while heavy containers that include thick walls, for example, may be quite strong, they are also costly due to the amount of material that goes into their manufacture. While modifying such containers to include less material by, using thinner walls, will decrease the cost of the container, the resulting container may not possess the required strength (e.g., top load strength) for certain applications. This disclosure describes an improvement over these prior art technologies.
