Perform extended finish for processing light weight ecologically beneficial bottles
Disclosed are preforms which incorporate improvements in the region of the neck and upper segment of the body to allow the production of lightweight containers, such as bottles suitable for containing water or other beverages. In accordance with certain embodiments, the improvements include a thinner neck finish area than conventional bottles, where the thinner area is extended into the upper segment of the body portion below the support ring. Reducing the thickness in these areas of the bottle allows for less resin to be used in forming the preform and bottle.
LIGHTWEIGHT PLASTIC CONTAINER AND PREFORM
A plastic container is provided that includes a hollow body portion including a lower supporting base portion; a sidewall portion extending upwardly from the base portion; and a neck portion extending upwardly from the sidewall portion. The neck portion includes a support flange having an upper and lower surface, at least one thread, and a dispensing opening at the top of the neck portion. In embodiments, a closure may be provided to form an assembly. In embodiments, the container may be comprised of PET, the weight of the neck portion from the lower surface of the support flange to a top of the dispensing opening may be 3.0 grams or less, and/or the vertical distance from the top of the dispensing opening to the lower surface of the support flange may be 0.580 inches or less. A preform and method for making a container are also disclosed.
Stretch-blow molded plastic container and stretch-blow-molding method
A stretch-blow molded plastic container includes a container body. A container neck, adjoins the container body via a shoulder region and has a container opening. The container body and the container neck are mutually separated by a support ring, which substantially radially protrudes, runs circumferentially in at least some regions and which has a support ring underside. The shoulder region has a first shoulder section, which runs in immediate proximity to the support ring underside, and a second shoulder support, which is integrally connected to the first shoulder support and which substantially radially adjoins the support ring. In a stretch-blow molding method a support ring of a preform, which is placed into a mold cavity of a blow molding tool, is overblown during radial and axial stretching of the preform.
LIGHTWEIGHT PLASTIC CONTAINER AND PREFORM
A plastic container includes a hollow body portion including a lower supporting base portion; a sidewall portion extending upwardly from the base portion; and a neck portion extending upwardly from the sidewall portion. The neck portion includes a support flange having an upper and lower surface, at least one thread, and a dispensing opening at the top of the neck portion. In embodiments, a closure may be provided to form an assembly. A preform and method for making a container are also disclosed.
LIGHTWEIGHT PLASTIC CONTAINER AND PREFORM
A plastic preform includes a hollow body portion including a closed base portion and a lower portion and a lower portion extending upwardly from the closed bottom portion; and a neck portion extending upwardly from the lower portion. The neck portion includes a dispensing opening positioned at a top of the neck portion, threads positioned below the dispensing opening, a tamper-evident formation having a lower surface and positioned directly below the threads, and a support flange having an upper surface and a lower surface and positioned below the tamper-evident formation. In an embodiment, the plastic preform is formed of a material comprising polyethylene terephthalate (PET), and a vertical distance from the lower surface of the tamper-evident formation to the lower surface of the support flange is from 0.125 to 0.150 inches. Containers and methods for molding preforms and making containers are also disclosed.
Lightweight plastic container and preform
A plastic container includes a hollow body portion including a lower supporting base portion; a sidewall portion extending upwardly from the base portion; and a neck portion extending upwardly from the sidewall portion. The neck portion includes a support flange having an upper and lower surface, at least one thread, and a dispensing opening at the top of the neck portion. In embodiments, a closure may be provided to form an assembly. A preform and method for making a container are also disclosed.

The neck portion includes a support flange having an upper and lower surface, threads, and a dispensing opening at the top of the neck portion. In embodiments, a closure may be provided to form an assembly. In embodiments, the container may be comprised of PET, the weight of the neck portion from the lower surface of the support flange to a top of the dispensing opening may be 2.3 grams or less, and/or the vertical distance from the top of the dispensing opening to the lower surface of the support flange may be 0.450 inches or less. A preform and method for making a container are also disclosed.
Perform Extended Finish For Processing Light Weight Ecologically Beneficial Bottles
Disclosed are preforms which incorporate improvements in the region of the neck and upper segment of the body to allow the production of lightweight containers, such as bottles suitable for containing water or other beverages. In accordance with certain embodiments, the improvements include a thinner neck finish area than conventional bottles, where the thinner area is extended into the upper segment of the body portion below the support ring. Reducing the thickness in these areas of the bottle allows for less resin to be used in forming the preform and bottle.
