A polyester-resin-coated seamless can including a reduced diameter portion obtained by neck processing within a distance of 0% to 15% from a can body uppermost portion with respect to a total height of the can from the can body uppermost portion to a can bottom of the can. A ratio Im/Iu is 1.0 or more, where Iu (cps/μm) is calculated by dividing a maximum peak intensity in a range satisfying 15°≤2θ≤19° of an outer-surface coating in a maximum reduced diameter portion of the reduced diameter portion by a thickness of the coating at the measurement site, and Im (cps/μm) is calculated by dividing a maximum peak intensity in a range satisfying 15°≤2θ≤19° of outer-surface coating at a measurement site within a distance of 45% to 60% from the can body uppermost portion by a thickness of the outer-surface coating at the measurement site.

Pressure reduction-absorbing bottle includes: cylindrical shoulder portion; cylindrical body portion connecting to the shoulder portion lower end; and bottom portion formed in cylindrical shape with bottom and connecting to the body portion lower end. The bottom portion includes: heel portion connected to the body portion lower opening section, and bottom wall portion closing the heel portion lower opening section. The bottom wall portion includes: grounding portion, rising circumferential wall portion, movable wall portion, and recessed circumferential wall portion. The movable wall portion capable of rotating around the connection portion with the rising circumferential wall portion to move the recessed circumferential wall portion in up-and-down direction. The body portion includes straight cylindrical part connecting to the shoulder portion lower end and extending downward. The straight cylindrical part outer diameter is greater than or equal to 0.60 times the heel portion outer diameter and is smaller than the heel portion outer diameter.

A plastic, hot-fillable container is provided. The container comprises a blow molded body including a neck and a base having a center portion and a plurality of spaced apart radial segments. At least a portion of each segment is tapered from an outer side to an inner side thereof. Container systems and methods of manufacturing containers are disclosed.

In a synthetic resin blow molded bottle, reduced pressure absorbing panel portions and column portions are formed alternately in the circumferential direction. Each column portion has a diameter that gradually increases downward and that remains substantially constant vertically. Each reduced pressure absorbing panel portion includes a pair of panel side edge portions, which is bent to the inner side from the adjacent column portions, a panel surface portion, which connects the pair of panel side edge portions, and a panel lower edge portion, which is bent to the outer side from a lower end edge of the panel surface portion. The panel surface portion of each reduced pressure absorbing panel portion includes a panel upper-side surface portion, whose diameter gradually increases downward, and a panel lower-side surface portion, which connects the panel upper-side surface portion and the panel lower edge portion and which has a substantially constant diameter vertically.

A blow molded bottle (1): a) which is self-collapsible during its emptying; b) which comprises at least two transversal grooves and/or ribs (6.1), preferably located in the tubular body portion (6), equipped with collapse starters (6.2); c) wherein the mean wall thickness (Tmean) of the tubular body portion (6) is—in an increasing order of preference—less than or equal to 200; 180; 160; 150 μm; preferably comprised between 65 and 150; and more preferably comprised between 90 and 130 μm. The invention also discloses a method, a preform (100) and a mold for the manufacture of the aforementioned container by blow molding. The invention also discloses a method for bottling liquid into the bottles (1), a method for dispensing the liquid, a dispenser for implementing the method and a method for packing the thin-walled bottles, in view of storage and transportation.

The present disclosure describes a hot-fill container for use with a hot-filling process. The container comprises vacuum absorption sections that resist partial collapse and uncontrolled deformation of the container's walls during the hot-filling process. The vacuum absorption sections are asymmetrically-formed and include respective edge portions and panel portions configured to deform and pivot about a linear part of the edge portions when a vacuum is created inside the container. The edge portions have a curvilinear part that is adapted to comfortably receive and engage a user's fingers during use of the container, making the container more user friendly. The vacuum absorption sections are arranged about the container's central longitudinal axis such that their respective panel portions substantially form the sides of a polygon when viewed in top plan view. The polygon appears to be inscribed within an otherwise circular container periphery.

A plastic container comprises an upper portion including a finish defining an opening into the container, a lower portion including a base defining a standing surface, a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis, and at least one substantially transversely-oriented pressure panel located in the lower portion. The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position.

An aseptic-fill beverage container can include a body and a base having a standing ring, a central portion, and an isolation ring that surrounds the central portion. One or more ribs can extend from the isolation ring to the standing ring such that the ribs do not extend outward the standing ring or inward to the central portion. The ribs can be s-shaped to provide rigidity and limit or prevent deformation to the base.

A polyethylene terephthalate composition (PET), an injection-molded bottle preform made from a PET composition, a refillable PET container blow-molded from the preform, catalyst compositions used for making the PET composition, methods for making the PET composition, methods for injection-molding a PET bottle preform, methods for blow-molding a refillable PET bottle from a preform and methods for improving the rewash stability and recyclability of refillable PET bottles particularly for carbonated soft drinks are disclosed. The polyethylene terephthalate composition includes a polyester resin containing terephthalic acid, isophthalic acid, ethylene glycol and cyclohexane dimethanol and residual amount of catalytic composition comprising Sb and Ti. The polyethylene terephthalate composition is especially useful for large blow moldings and provides a change in the fill point volume after 5 wash cycles of a 2.5 liter blow molded bottle of 14 ml or less.

A plastic container comprises an upper portion including a finish adapted to receive a closure, a lower portion including a base, and a sidewall extending between the upper portion and the lower portion. The upper portion, the lower portion, and the sidewall define an interior volume for storing liquid contents. The plastic container further comprises a pressure panel located on the container and moveable between an initial position and an activated position. The pressure panel is located in the initial position prior to filling the container, and is moved to the activated position after filling and sealing the container. Moving the pressure panel from the initial position to the activated position reduces the internal volume of the container and creates a positive pressure inside the container. The positive pressure reinforces the sidewall. A method of processing a container is also disclosed.
