A polymeric container including a finish defining an opening of the container. A body defines an internal volume for storing product therein. A base is at an end of the body opposite to the finish. The base defines a plurality of recesses spaced apart from one another about an axial center of the base.

Container base with deep inset recesses

A container including an opening defined by a finish portion. A base is at an end of the container opposite to the opening. The base includes a deep base ring between a standing surface and a truncated cone at a center of the base. The truncated cone is mechanically movable a displacement distance from an as-blown position to a displaced position subsequent to hot-filling and capping of the container to reduce an internal volume of the container. In the displaced position, the truncated cone is closer to the opening than in the as-blown position.

Vertical displacement container base

A method for hot-filling a polymeric container with heated product. The method includes mechanically inverting a base of the polymeric container prior to the heated product cooling in order to create a positive pressure within the container prior to cooling, and a vacuum in the container after cooling.

Method of inverting container base prior to cooling

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 multi-serve polymeric container having a finish defining an opening of the container, a body, and a base. The body and the base have a substantially oval shape in cross-section, which enables the use of smaller finishes and provides for lighter weight containers.

Multi-serve container with oval cross-section

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 defining a longitudinal axis and a transverse direction that is transverse with respect to the longitudinal axis. The container includes a finish and a sidewall portion extending from the finish. A plurality of ribs are defined by the sidewall. A base portion extends from the sidewall portion and encloses the sidewall portion to form a volume therein for retaining a commodity. The base portion has a contact surface for supporting the container. A plurality of straps extend radially along the base portion away from the longitudinal axis in the transverse direction, each one of the straps defines a strap surface that is closer to the finish than the contact surface. The plurality of ribs and the base portion are configured to place the container in a state of hydraulic charge-up when top load is applied to the container after the container is filled.

Lightweight container base

A method for manufacturing and filling a container. The method includes blow molding the container from a preform. The container is then hot filled and cooled. After cooling, the container is labeled. A top load force is applied to the container at least one of: before cooling the container; during cooling of the container; after cooling the container and before labeling the container; during labeling of the container; and after labeling the container in order to reverse any dents in the container formed during the method of manufacturing and filling.

Method of applying top load force

A method of inspecting a blow molded container having a finish, a base, a body between the finish and base, and etching at the base. The method includes identifying where on the base the etching is located, designating the base as accurately blow molded if the etching is located at a predetermined location of the base, and designating the base as not accurately blow molded if the etching is not located at the predetermined location of the base.

Etched preform tip

A container including an opening defined by a finish portion, and a base at an end of the container opposite to the opening. The base includes a standing ring extending inward from a heal to a center pushup portion. The center pushup portion includes an pushup ring surrounding an inversion portion. In an as-blown position the inversion portion extends outward and beyond the pushup ring such that the inversion portion is further from the opening than the pushup ring. In a final position the inversion portion is inverted relative to the as-blown position such that the inversion portion extends inward so as to be closer to the opening than the pushup ring. The inversion portion is mechanically moved from the as-blown position to the filled position with an inversion device after the container has been filled to reduce vacuum or increase pressure within the container.

A mold system for forming a container having a longitudinal axis and a transverse direction that extends transverse to the longitudinal axis. The mold system includes a sidewall system for molding the sidewall portion of the container. The mold system also includes a base system for molding the base portion of the container. The base system is operable for forming the entire base portion of the container including a central pushup portion, a contact surface for supporting the container, and at least one strap extending along the base portion in the transverse direction. The strap defines a strap surface that is spaced offset in a direction parallel to the longitudinal axis from the contact surface. The strap surface extends in the transverse direction to be adjacent the sidewall portion such that the at least one strap surface is visible from a side of the container.

A preform configured to form a container by stretch blow molding. A finish portion is at a first end of the preform, and is a container finish. A tip portion is at a second end of the preform opposite to the first end, and is configured to form a container base and a container heel. The shoulder portion is adjacent to the finish portion and is between the finish portion and the tip portion. The shoulder portion is configured to form a container shoulder. The body portion is between the shoulder portion and the tip portion, and is configured to form a container body. The outer surface includes a first flat portion and a second flat portion at the tip portion. The first flat portion extends at a first angle and the second flat portion extends at a second angle that is different than the first angle.
