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 container having enhanced wall integrity is provided that includes a sidewall having a polygonal cross-sectional shape and an alignment structure formed therein. The alignment structure is adapted for orienting the container with respect to a second container such that the panel sections of the containers become parallel with one another, and the containers may be fully nested one within the other. The alignment structure may include a generally parabolic-shape protrusion that extends radially outwardly relative from the sidewall to form peaks along an external surface of the container and valleys along an inner surface of the container. The peaks are adapted to direct corners of the first container's sidewall toward the corners of the second container's sidewall in order to orient the containers as they are stacked.

Described is an assembly (1) comprising a wall element (2), defining a circumferential bonding strip (3) running over the wall element, and a flexible flat film connected to the bonding strip with a continuous circumferential bonding (4), which wall element and film define two opposite walls (2a, 5a) of a chamber (5), characterized in that the wall element further comprises a base plane B defined by the wall element, at least two corner elements (6a, 6b, 6c, 6d) positioned on a distance to one another, which extend substantially perpendicular with a height H (Ha, Hb, Hc, Hd) in the same direction from the base plane of the wall element, each corner element defining an angle A (Aa, Ab, Ac, Ad) of the chamber with an angle line which is substantially perpendicular to the base plane, strip sections (7a, 7b, 7c, 7d), each connecting two corner elements that define adjacent corners of the chamber to one another, the distance between the strip sections and the base plane being less than H, wherein the continuous circumferential bonding strip runs over the strip sections and over the corner elements and at least in the area of the corner elements at a distance from the base surface corresponding to height H (Ha, Hb, Hc, Hd), and wherein the outer contour of the film is shaped in such a way that the outer contour of the film corresponds to that of the circumferential bonding strip. A method for the production of such an assembly is also described.

A storage tote includes a main body with a base wall and a plurality of side walls. The base wall has a center area, a central ridge, a first side ridge, and a second side ridge. The center area is bounded by the plurality of side walls. The central ridge bisects the base wall. In addition, the central ridge has a first wall, a second wall, and a third wall. The first side ridge and the second side ridge are disposed across the center area and oriented parallel to the central ridge. The first side ridge is spaced apart from the first wall of the central ridge, while the second side ridge is spaced apart from the second wall of the central ridge.

A lightweight neck finish includes a retaining structure that interacts with a tamper band to cause frangible connectors between the tamper band and closure to break upon initial removal of the closure from the neck finish. An upper retention portion of the retaining structure has a profile with a reduced footprint as compared to a conventional retaining structure. A lower support portion of the retaining structure has an outermost diameter similar in size to an outermost diameter of a conventional retaining structure. However, the lower support of the lightweight neck finish is formed with one or more circumferentially extending slots and/or one or more vertical slots. The reduced footprint of the retention portion and the slots of the support portion minimize the amount of material, weight, and time and cost required to make the lightweight neck finish, while providing for increased tamper evidence visibility as compared to conventional neck finishes.
