VARIABLE DISPLACEMENT BASE AND CONTAINER AND METHOD OF USING THE SAME

Hot-fillable plastic bottle including a finished portion, a body portion with at least one circumferential rib configured to resist radial distortion, and a base portion. The base portion comprises a base sidewall, a bottom support surface extending radially inward from the base sidewall and defining a reference plane, an inner support wall extending upwardly from the bottom support surface, and a diaphragm extending radially inward from the inner support wall. The diaphragm comprises an inner wall having an arcuate shape with a radius r1 and a central conical structure, where the diaphragm is in an initial as-formed position with the conical structure above the reference place. The diaphragm is configured to move from an initial as-formed position toward a second position when an internal pressure relative an external pressure exceeds a threshold value.

Dome Formation Profile & Method of Lightweight Container Design and Manufacture
20190055074 · 2019-02-21 ·

The inventive technology includes a novel container dome profile and manufacturing process for improving container and bottle deformation failure resistance and extending material displacement modes through an initial deformation panel coordinated with complimentary geometric paneling and buttressing structures configured to initiate a controlled sequential dome profile deformation mode. Dome reversal, dome growth, and dome drop resistance characteristics are improved with a shallower profile formation depth, reducing pulldown, and lowering material consumption, resulting in lower overall container/bottle weight. Novel geometric contoured shapes enhance container resistance performance, supporting use of softer alloys or lower temper and yield strength to benefit post-processing efficiency and forming processes improvements while being configured to initiate controlled sequential dome profile deformation.

Lightweight Container Base
20190047741 · 2019-02-14 ·

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.

METHOD FOR SHAPING THE BOTTOM OF HOT-FILLED CONTAINERS

A method is described for shaping the bottom of hot-filled containers, in which the bottoms of the containers are forced inwardly from a state bulged outwardly, in particular as they cool down. Complex mechanisms for forcing the bottom inwardly are dispensable for the reason that the bottoms are forced inwardly by at least one fluid jet and/or fluid pressure wave. In addition, shaping the bottom can advantageously be carried out in a production region immediately downstream of a closer.

Flexible panel to offset pressure differential

Provided is a container that includes a top having an opening configured to receive a product. The container also includes a bottom adjoining a sidewall that extends to the top of the container and a flexible panel disposed on the bottom and having a plurality of surfaces that each extend radially around a longitudinal axis of the container. One of the plurality of surfaces comprises a downward ramp that extends away from the top of the container when moving radially inward along the downward ramp and another of the surfaces comprises an upward ramp that extends toward the top of the container when moving radially inward along the upward ramp. The surfaces may include dimples protruding inward from the outer surface of the container that have an interlocking pattern.

Plastic containers having base configurations with up-stand walls having a plurality of rings, and systems, methods, and base molds thereof

Plastic containers, base configurations for plastic containers, and systems, methods, and base molds thereof. In particular, the disclosed subject matter involves container base configurations having particular up-stand geometries that can assist or facilitate elevated temperature processing and/or cooling processing of plastic containers.

A bottle includes a bottom wall portion of a bottom portion, grounding portion at an outer circumferential edge, rising circumferential wall portion continuous with grounding portion from the bottle radial inner side, and movable wall portion protrudes from the rising circumferential wall portion upper end. The movable wall portion movable upward around a connected portion to the rising circumferential wall portion. Plurality of ribs are radially disposed around bottle axis on the movable wall portion, and ribs include main recess that is recessed upward, and connection recess. Plurality of main recesses arranged at predetermined intervals in the bottle radial direction, and connection recess connects main recesses, adjacent to each other in the bottle radial direction, in the bottle radial direction together. A depth ratio D2/D1 that is the ratio of a depth (D2) of the connection recess to a depth (D1) of each main recess <2/9 and 1.

Container system and method of manufacture

A plastic, hot-fillable container is provided. The container comprises a blow molded body defining a longitudinal axis. The body including a base and a neck having at least one rib disposed about at least a portion of a circumference of the neck and transverse to the axis, and at least one angled thread. The at least one rib defining a cross section having a first portion and a second angled portion. Container systems and methods of manufacturing containers are provided.

Reclosable plastic bottle with waist and strengthening rib(s)

The present disclosure is directed to a bottle made of polyethylene terephthalate (PET) and having a circular cross-section. The bottle has a sidewall spanning between a neck finish and a base. The sidewall includes a shoulder portion and a panel portion, with the lower end of the shoulder portion and the upper end of the panel portion each sloping inward to create a waist. One or more circumferential ribs are positioned within the waist, and preferably at the trough of the waist. The one or more circumferential ribs are designed and configured to increase the hoop strength of the bottle, the vacuum stability of the bottle, or both.
