A polymeric container including a finish defining an opening of the container, a base, and a body. The body is between the finish and the base. The body includes a flexible panel extending entirely around the container A longitudinal axis of the container extends through an axial center of the finish, the base, the body, and the flexible panel. The flexible panel includes alternating concave portions and vertically extending columns arranged about the flexible panel. In response to a vacuum within the container resulting from filling and capping the container, the concave portions are configured to flex inward towards the longitudinal axis to become more concave, and the vertically extending columns are configured to flex outward away from the longitudinal axis of the container.

Polymeric container including a body with a plurality of oscillations

A polymeric container including a finish defining an opening. A base is configured to support the container upright. A grip area is between the opening and the base. A plurality of grip panels are at the grip area. Each one of the grip panels has a depth, a height, and a width. The depth is at least 17% of the height, and the depth is at least 10% of the width.

Container grip panel with improved side load

A method of forming a container and filling the container with a product. The method includes heat-set blow molding the container from a preform and hot-filling the container with the product such that the product occupies about 95% or more of a total interior volume of the container. A headspace volume is defined between a top fill line of the product and a brim of the container. The headspace volume is less than about 5% of the total interior volume of the container. The container is capped and allowed to cool. The container is configured to shrink during cooling such that the total interior volume decreases by about 0.5% to 1.5% during cooling. A base of the container is displaced after hot-filling and capping to reduce the total interior volume by less than about an additional 0.5% to 4%. The hot-filling, capping, cooling, and displacing of the base creates a pressure change within the container.

Method of controlling vacuum and pressure within a thermoplastic container

A container including a finish defining an opening at a first end of the container that provides access to an internal volume defined by the container. A base portion of the container includes a diaphragm that is concave relative to an exterior of the container. The diaphragm extends from a standing surface of the container to a center push-up portion of the base portion. The standing surface is at a second end of the container opposite to the first end. The diaphragm is configured to move from an as-blown first configuration to a second configuration in which the diaphragm is closer to the first end as compared to the first configuration in order to reduce residual vacuum within the container. The diaphragm is generally hemispherical in cross-section when in the second configuration.

Container base including hemispherical actuating diaphragm

A container including a finish defining an opening at a first end of the container that provides access to an internal volume defined by the container. A base portion of the container includes a diaphragm that is concave relative to an exterior of the container. The diaphragm extends from a standing surface of the container to a center push-up portion of the base portion. The standing surface is at a second end of the container opposite to the first end. The diagram is configured to move from an as-blown first configuration to a second configuration in which the diaphragm is closer to the first end as compared to the first configuration in order to reduce residual vacuum within the container. The diaphragm is generally hemispherical in cross-section when in the second configuration.

A blow-molded container including a finish and a base. The finish defines an opening at a first end of the container that provides access to an internal volume. The base includes a diaphragm and a standing surface. The diaphragm extends radially outward from a central push-up portion. The standing surface of the container is at a second end of the container. In response to an internal vacuum caused by hot-filling and closing the container, the diaphragm is configured to move passively from an as-blown first configuration to a second configuration in which the diaphragm is closer to the first end of the container as compared to the as-blown first configuration. The diaphragm is configured to move from the second configuration to an activated third configuration in which the diaphragm is closer to the first end of the container in response to the diaphragm being externally actuated by a tool.
