Estimating the term…
Injection molded and injection blow molded multi-layer plastic articles, parisons and containers are provided, which, in preferred embodiments are substantially rigid and have at least three layers wherein a portion of the marginal end portion of their internal layer is folded over within the marginal end portion of the side wall of the article, preferably in the flange if the article is a parison or container. The articles folded over portion can be toward the inside or the outside of the side wall. The articles, parison, and containers can be open-ended, or closed, for example, with end closures double seamed thereto or flexible lids secured thereto by an adherent, or heat seal, or other suitable means. The folded over portion and any not folded over portion of the internal layer preferably extends substantially uniformly into the marginal end portion of the side wall.
An injection moled, multi-layer plastic article having a multi-layer integral side wall which has an internal layer, a terminal end portion of which is folded over within the side wall.
An injection molded, multi-layer plastic parison for forming a blow molded container wherein said parison has a multi-layer integral side wall which has an internal layer, a portion of which is folded over within the side wall.
An injection blow molded, multi-layer plastic article having a multi-layer integral side wall which has an internal layer, a portion of which is folded over within the side wall.
An injection blow molded, multi-layer rigid plastic container having a multi-layer integral side wall which has an internal layer, a portion of which is folded over within the side wall.
An injection molded, multi-layer plastic article, having a multi-layer integral side wall comprised of an outside surface layer, and inside surface layer, and an internal layer between said inside and outside surface layers, wherein the side wall has a terminal end portion and the internal layer has a terminal end, and wherein a portion of the terminal enddportion of internal layer is folded over within the side wall, whereby the terminal end of the unfolded portion of the internal layer and the fold line of the folded over portion of the internal layer are located in the terminal end portion of the side wall.
An injected molded multi-layer container wherein the container has a multi-layer integral side wall having an internal layer and having a marginal end portion, the internal layer having in said marginal end portion a leading edge whose plane is substantially unbiased relative to the axis of the container said leading edge being comprised of the fold line of a folded over portion of said internal layer.
An injection molded multi-layer plastic article having a multi-layer integral side wall which has a terminal end and which has an internal layer whose terminal end is more removed from the terminal end of the article than is another adjacent directionally related marginal end portion of the internal layer.
An injection molded multi-layer plastic article having a multi-layer side wall which has an internal layer having a fold line from which there extends a folded over portion, and a terminal end at the end of the folded over portion and which is more removed than the fold line is from the terminal end of the article.
An injection molded-multi-layer plastic article having a terminal end, and a multi-layer integral side wall which has an internal layer having a fold line and a terminal end, wherein there is less variation in the distance from the fold line to the terminal end of the article than from the terminal end of the internal layer to the terminal end of the article.
An injection molded multi-layer plastic article having a terminal end, and a multi-layer integral side wall which has an internal layer having a marginal end portion and a terminal end, wherein a portion of the marginal end portion is folded over along a fold line, such that the folded over portion lies near another portion of the internal layer, and the terminal end of the internal layer is more removed than the fold line is from the terminal end of the article.
An injection-molded, multi-layer plastic article having a multi-layer integral wall which has an internal layer, a portion of which is folded over within the wall.
An injection blow-molded, multi-layer plastic article having a multi-layer integral wall which has an internal layer, a portion of which is folded over within the wall.
An injection-molded, multi-layer plastic parison for forming a blow molded container wherein said parison has a multi-layer integral wall which has an internal layer, a portion of which is folded over within the wall.
An injection blow-molded, multi-layer plastic parison for forming a blow molded container wherein said parison has a multi-layer integral wall which has an internal layer, a portion of which is folded over within the wall.
An injection-molded, multi-layer plastic container having a multi-layer integral wall which has an internal layer, a portion of which is folded over within the wall.
An injection blow-molded, multi-layer plastic container having a multi-layer integral wall which has an internal layer, a portion of which is folded over within the wall.
