Definitions

• This invention relates to containers, and more particularly to plastic containers capable of flexing in response to changes in internal pressure.
• Plastic containers for perishable products are often filled at an elevated temperature in a process generally known as hot- filling, which includes filling the product at about 185 degrees F and immediately sealing the container. After sealing, the contents of the container contract upon cooling, which creates a vacuum condition inside the container.
• Many conventional cylindrical containers would deform or collapse under the internal vacuum conditions without some structure to prevent it.
• some containers have panels, referred to as "vacuum panels,” located in the panel sidewall.
• the vacuum panels are configured to inwardly and easily flex in response to internal vacuum such that the remainder of the container body remains cylindrical.
• the structure between the vacuum panels, such as vertical posts is stiff relative to the vacuum panels.
• the vacuum panels are located about the circumference of the body of the container and then covered by a label that wraps around the circumference to hide the vacuum panels and posts.
• the vacuum panels of many bottles are generally rectangular. Often, deformation of a generally rectangular vacuum panel causes high stress areas at the corners and in the areas outside the vacuum panels near the corner.
• a container that includes an enclosed base, an upper portion that extends upwardly to a finish; and a body located between the base and the upper portion.
• the body includes a sidewall having at least one vacuum compensation element generally having a V-shape.
• the element comprises a first field, a second field, and a third field.
• the first field is nested within the second field
• the second field is nested within the third field.
• the elements are closed on one of an upper end and a lower end and generally open on the other one of the upper end and the lower end.
• a plastic hot- fill bottle may include: an enclosed base, an upper portion that extends upwardly to a finish, and a body located between the base and the upper portion.
• the body includes a sidewall having at least one circumferentially spaced, vacuum compensation elements.
• Each one of the elements comprises a first field, a second field, and a third field.
• the first field is nested within the second field
• the second field is nested within the third field.
• the elements are generally enclosed on one of an upper end and a lower end and generally open on the other one of the upper end and the lower end.
• the element open end smoothly merges into the container sidewall.
• the elements may be V-shaped.
• a plastic hot- fill bottle may include: an enclosed base, an upper portion that extends upwardly to neck and a finish, and a body located between the base and the upper portion.
• the body includes a sidewall comprising: at least two vacuum compensation elements, and at least two panels, wherein the elements and panels are disposed around the circumference of the body in an alternating manner, and wherein the vacuum compensation elements have a generally V-shape.
• the elements comprise: a first field, a second field, and a third field. The first field is nested within the second field, and the second field is nested within the third field.
• the elements are generally closed on one of an upper end and a lower end and generally open on the other one of the upper end and the lower end.
• a label panel may be provided that is spaced apart from the elements.
• the container has an even number of circumferentially spaced, vacuum compensation, flared elements, which may provide enhanced support of the sidewall.
• Ribbed or stepped eyebrows may be located adjacent to the closed end of a field.
• Each field or element may include a tip, transition portions, and lateral portions that are defined by ridges.
• each one of the fields forms a face that is overall flat.
• the container may have, for example, four elements such that the container body is approximately square in transverse cross section before and after hot-filling.
