A multilayer structure includes a layer of a resin composition containing an ethylene-vinyl alcohol copolymer and a thermoplastic elastomer, wherein a mass ratio of the ethylene-vinyl alcohol copolymer to the thermoplastic elastomer is from 65/35 to 95/5 and the layer of the resin composition has one surface directly adjacent to a layer of polyolefin with no polar functional group. A multilayer structure is thus provided that is excellent in gas barrier properties, transparency, and flexibility and also has good delamination properties between the layer of the resin composition and the layer of the polyolefin with no polar functional group.

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.

A protective bottle enclosure for removably enclosing a bottle having a bottleneck ending in an open mouth. The enclosure includes a base section, a body, and a removable cap. The base section includes a cylindrical base sidewall secured to a perimeter of a base bottom wall and an open top. The body can removably engage the base section to cover the open top thereof. The removable cap includes a cap sidewall and a stopper that can removably engage the open mouth of the bottle. The stopper includes a stopper body and an annular ring extending radially outward from the stopper body. In use, the protective bottle enclosure can surround the bottle and seal the open mouth of the bottle when the base section is engaged with the body and the removable cap is engaged with the neck section.

A bottle, or a generic container, for the tight storage of diverse materials, may comprise a circular lip at the top of its neck finish or opening with an inferiorly disposed smooth, slanted and curved outer surface that is punctuated by equally spaced indentations and that may extend outwards and stepwise downwards, first through a vertical and then a convex surface and finally to a smooth surface on which may be disposed a button protrusion. A tightly sealed finish may be characterized by its lip and the equally spaced protruding lugs disposed on its inner surface interacting tightly with threading and other parts of the inner part of a reusable aggregate cap which, in turn, may inextricably couple with an outer part on whose outer annular flange surface may be disposed a button marker protrusion that, because of inaccessible features and mechanisms on the cap units, may only align with the one on the outer surface of the finish or opening of an unopened bottle or container. Determination of whether a tightly capped container has been previously opened or tampered with, may quickly be performed, either visually or through touch, by checking the alignment, or not, of the externally exposed button protrusions.

A method for manufacturing a container includes injecting a first material into a first mold to form a top portion of a preform. The first material and a second material are injected into the first mold to form a bottom portion of the preform. The preform is disposed in a second mold. The preform is blow molded into a finished container.

A sidewall of a container for storing liquid contents includes a grip portion extending from a base of the container and presenting a grip portion periphery about an axis. A plurality of axially angulating ribs are within the grip portion, each of which includes a first portion having a first radial depth relative to the periphery that transitions to a second portion having a second radial depth relative to the periphery less than the first radial depth. A flat portion having a zero radial depth relative to the periphery is positioned circumferentially between a second portion of one angulating rib of the plurality of axially angulating ribs and an axially offset second portion of another angulating rib of the plurality of axially angulating ribs.

A degradable containment includes an outer structural layer constructed of a pulp material, a central carrier layer constructed of a biopolymer, and an interior nanomaterial layer constructed of a nanomaterial.

A thermoplastic bottle is provided that has a sidewall having an exterior surface that defines a plane curve. The sidewall is joined with a base and a mouth to define an interior volume. Facets are integrally formed in the sidewall that each have a recess interior to the plane curve and a protrusion extending above the recess. The protrusion being either above or below the plane curve. The recess can surround the protrusion or be adjacent thereto. Facets can be arranged in a variety of patterns and vary in shape, size, or both relative to one another. A ratio is defined for a recess depth to an absolute value of a height of a protrusion of 0.2-5:1. The resulting bottle offers a better grip when fluid bottle contents have dripped on the exterior surface relative to a conventional bottle. By allowing the drippage to seep into recesses of the facets.
