Disclosed is an injection stretch blow molded (ISBM) container containing a surface having a static coefficient of friction (COF) of 0.15 to 0.21, a dynamic COF of 0.06 to 0.1, wherein the surface retains a water contact angle of 76° or higher for up to three minutes after wetting of the surface with a water drop of 14 to 16 mm diameter and the container is made with a polymeric composition containing a high density polyethylene (HDPE) having a dispersity (Mw/Mn) of 9 or higher as measured by GPC; a MI2 of 1 g/10 min or higher as measured by ASTM D-1238; 190° C./2.16 kg, as measured by ASTM D-1238; and an environmental stress crack resistance (ESCR) at 100% Igepal of >150 hours as measured by ASTM D-1693, B.

Hinged container cap, comprising a base portion, a hinge member and a lid, wherein the base portion is made of a crystallisable polymer and includes a base circumferential wall and a base containment wall having an base outlet aperture and has an external base surfaceexternal base surface 44, wherein the hinge member connects the base portion to the lid and allows a movement of the lid between an opened position, in which the base outlet aperture is open, and a closed position, in which the base outlet aperture is closed, wherein in the closed position, at least part of the external base surfaceexternal base surface 44 of the base portion forms an interface with the lid contact surfacelid contact surface 42 of the lid, wherein the base portion and/or of the lid wall is crystallized at at least the interface of the base portion and the lid in the closed position, to allow the lid to be opened after being closed for an elongated period.

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.

A freezable reusable bottle having a body and a cap engaged with the body. The body includes a container portion and a neck portion extending from the container portion. The container portion includes a plurality of ribs extending along a longitudinal axis of the reusable bottle. The cap removably engages with the neck portion of the body. The body includes a polymer composition of about 85 to 90 percent of polypropylene (PP) and about 10 to 15 percent of an SEBS additive. The bottle may be frozen when filled with a liquid, with the ribs accommodating expansion of the contents during freezing, and the additive providing impact resistance accommodating the rigid frozen contents.

Plastic container comprises a container body having a bottom portion, a sidewall portion and an upper portion, with a chamber defined therein. The bottom portion includes a support surface and a variable dynamic base portion. The sidewall portion includes a lower circumferential groove ring, an upper circumferential groove ring, and a pair of longitudinal grooves extending longitudinally therebetween to define a front sidewall segment and a rear sidewall segment. The rear sidewall segment comprises a waist groove extending circumferentially between the pair of longitudinal grooves to define an upper rear sidewall segment and a lower rear sidewall segment, wherein one of the upper rear sidewall segment or the lower rear sidewall segment includes two vacuum panels with a rigid longitudinal support therebetween.

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.

Apparatuses and methods for inspecting a pharmaceutical cylindrical containers are provided. The apparatus includes a support device, a light emitting unit, and a light receiving unit. The support device supports the pharmaceutical cylindrical container and rotates the cylindrical pharmaceutical container around a longitudinal axis. The light emitting unit has a light source that illuminates the pharmaceutical cylindrical container with a detection beam while the support device rotates the pharmaceutical cylindrical container. The light receiving unit has a camera that acquires polarization information of the detection beam.
