In some embodiments, a tamper evidence closure engages with threads of a finish of the container. Cam locks around the perimeter of the tamper evidence closure are permanently flared by cams on the finish during loosening of the closure. Outward flaring of the cam locks provides a visual indication that the tamper evidence closure has been loosened after installation by a manufacturer.

Abstract: An apparatus and methods are provided for a lightweight shrink-wrapped bottle pack. The shrink-wrapped bottle pack comprises a group of bottles arranged in a side-by-side disposition. A case wrapping film is shrink-wrapped around the group of bottles to fixate the side-by-side disposition. Holes in the case wrapping film allow top portions of the bottles to protrude through the case wrapping film. A portion of the case wrapping film surrounding each of the holes forcibly contacts a bell comprising each bottle such that the case wrapping film fixates the side-by-side disposition of the group of bottles. The holes facilitate using a shorter portion of case wrapping film than when extending the case wrapping film over the top portion of the group of bottles, producing a lighter weight bottle pack than conventionally shrink-wrapped bottle packs.

Abstract: 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.

Abstract: An apparatus and methods are provided for a container closure that includes a tether that keeps the closure coupled with a plastic container after the closure has been unsealed to access contents within the container. The container closure comprises a closure portion coupled to a tamper evidence band by a tether bridge. The closure portion threadably engages with a finish portion of the container and seal contents in an interior of the container. The tamper evidence band remains engaged with the finish portion when the closure portion is removed from the finish portion. A multiplicity of thin connections between the tamper evidence band and the closure portion break apart when the closure portion is untightened from the finish portion. The tether bridge remains unbroken and is configured to allow the closure portion to be tilted away from the finish portion by an end-user.

Abstract: An apparatus for a nozzle is provided for engaging with lightweight preforms for blow-molding the preforms into plastic containers without damaging the finish portion of the preforms. The nozzle comprises a first cylindrical portion including a first seal, a second cylindrical portion including a second seal, and a tapered portion between the first and second cylindrical portions. The first and second cylindrical portions include diameters that are less than respective diameters of interior surfaces within the finish portion. The first and second seals are disposed around respective circumferences of the first and second cylindrical portions and configured to tightly engage with the interior surfaces of the preform while maintaining clearance between the nozzle and the interior of the finish portion. In some embodiments, the seals are configured to stabilize an orientation of the preform after being pressed onto the nozzle and facilitate conveying the preform along a manufacturing line.

Abstract: A bottle may have varying depth ribs to achieve a balance of strength and rigidity while maintaining hoop strength. The varying depth ribs may smoothly transition around the circumference of the bottle from a flattened and/or shallow depth rib portion to a deep rib portion. A collection of flattened and/or shallow depth ribs act as recessed columns in the body of the bottle to resist bending, leaning, crumbling, and/or stretching. The deep rib portions provide hoop strength and make the bottle body more rigid and/or stiffer when gripped by a user. A balance may be achieved between of flattened and/or shallow depth ribs and deep ribs to attain a desired resistance to bending, leaning, and/or stretching while maintaining stiffness in a lightweight bottle.
