摘要:
A blow-molded plastic container comprising a base portion having a flexible standing ring radially extending therefrom. The flexible standing ring is disposed about a lowest most portion of the container and operable to support the container on a surface. The flexible standing ring defines an annular groove thereabout that collapses in response to internal vacuum forces and/or external loading forces. The container further comprises a body portion that extends from an upper portion to the base, such that the upper portion, the body portion and the base cooperate to define a receptacle chamber within the container into which product can be filled.

An apparatus for simultaneously forming and filling a plastic container is provided. A mold cavity defines an internal surface and is adapted to accept a preform. A pressure source includes an inlet and a piston-like device. The piston-like device is moveable in a first direction wherein liquid is drawn into the pressure source through the inlet and in a second direction wherein the liquid is urged toward the preform. A blow nozzle may be adapted to receive the liquid from the pressure source and transfer the liquid at high pressure into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and creating a resultant container. The liquid remains within the container as an end product.

A tool for perforating a polymeric film is disclosed. The tool comprises a support substrate and at least one projection (3) extending from the substrate. The projection is multi-sided with side walls that have straight sides that are tapered upwardly and inwardly from the support substrate at an angle theta (θ) that is at least 5°. The angle is measured in relation to imaginary lines extending perpendicularly to the substrate at the locations at which the side walls contact the substrate.

A plastic container has an upper portion including a mouth defining an opening into the container. A shoulder region extends from the upper portion. A sidewall portion extends from the shoulder region to a base portion. The base portion closes off an end of the container. An upper bumper portion is defined at a transition between the shoulder region and the sidewall portion. The upper bumper portion includes an upper raised wall defining a maximum width of the container. The upper raised wall includes a recessed portion formed therein. A lower bumper portion is defined at a transition between the base portion and the sidewall portion. The lower bumper portion includes a lower raised wall defining the maximum width of the container. The lower raised wall includes a recessed portion formed therein.

A one-piece plastic container includes a container body and an upper portion having a finish. Integrally formed with the finish and extending downward therefrom is a shoulder region. The shoulder region merges into and provides a transition between the finish and a sidewall portion. The sidewall portion extends downward from the shoulder region to a base portion having a base. The sidewall portion defines a series of horizontal lands and horizontal ribs. The horizontal lands and horizontal ribs extend continuously in a vertical direction from the shoulder region to the base portion. The horizontal ribs are designed to achieve optimal performance with regard to vacuum absorption, top load strength capabilities and dent resistance.

The polymeric composition comprising (A) a polyester resin and (B) micrometrical silica particles, preferably particles made of cristobalite or quartz, dispersed in the polyester resin preferably at concentration of at least 2 wt %. The polyester resin preferably comprises a PET homo or copolymer. Packaging articles, especially biaxially stretched blow moulded containers, made with the said polymeric composition exhibit high opacity to UV and visible light radiations as well as improved barrier properties to O2 and to water vapour, and improved thermal and mechanical properties.
摘要:
A rectangular plastic container having a shoulder region adapted for vacuum pressure absorption, a sidewall portion having a rigid support ledge and a tapered base structure having an octagonal shaped footprint. The shoulder region including vacuum panels being moveable to accommodate vacuum related forces generated within the container. The shoulder region, sidewall portion and base each having differing horizontal cross sectional shapes.

A system for controlling a design process having a first design sub-process and a second design sub-process, outcomes of one of the first and second design sub-processes being linked to outcomes of the other of the design sub-processes by a relationship between one or more first design sub-process variables and one or more second design sub-process variables. The system comprises a user configurable interface between the first and second design sub-processes, the interface allowing a user to the system to control the design process by specifying which of the one or more variables are active variables which can have their domains modified by at least one process within the sub-process to which the variable belongs and which of the one or more variables are passive variables which have their domains determined within allowable values by the domains of the other variable(s) in the relationship.
摘要:
According to the present invention there is provided a carton suitable for transporting bottles, the carton including: i) a series of side wall panels that are interconnected and form an enclosure and can be manipulated from an empty collapsed orientation for storage in a space saving manner to an assembled orientation into which bottles can be loaded; and ii) an internal wall structure positioned inside and connected to the side wall panels at pre-selected locations such that as the enclosure is manipulated from the collapsed orientation to the assembled orientation the internal wall structure is located in an operative position which defines separate compartments each adapted to receive a bottle and thereby avoid bottles loaded into the carton from contacting each other.
