Estimating the term…
The present invention is directed to a pourable, hot wash, refillable container comprising a base, a cylindrical body having an average side wall thickness of at least 0.635 mm, a shoulder portion, and a neck portion, the pourable, hot wash, refillable container being composed of polyethylene napthalate or a copolymer thereof, the refillable container being capable of undergoing multiple trips through a washing, filling, shipping and consumer use cycle, and the base of the container having sufficient impact resistance so that the container will not break when dropped one meter onto a concrete surface when filled with water at both 4.4.degree. C. and 22.2.degree. C. The invention is further directed to a method for manufacturing a pourable, hot wash, refillable container, which comprises the steps of forming a preform of the container composed of polyethylene napthalate or a copolymer thereof, and molding said preform to form a pourable, hot wash, refillable container.
A pourable, hot wash, refillable container comprising a base, a cylindrical body having an average side wall thickness of at least 0.635 mm, a shoulder portion, and a neck portion, said pourable, hot wash, refillable container comprising polyethylene napthalate homopolymer, said container being capable of undergoing multiple trips through a washing, filling, shipping and consumer use cycle, and said base of said container being oriented and having sufficient impact resistance so that said container will not break when dropped one meter onto a concrete surface when filled with water at both 4.4.degree. C. and 22.2.degree. C., said base of said container being oriented by the process of blow-molding a preform wherein the preform stretch ratio is in the range of 5 to 9.
A pourable, hot wash, refillable container comprising a base, a cylindrical body having an average wall thickness of at least 0.635 mm, a shoulder portion, and a neck portion, said pourable, hot wash, refillable container being composed of a copolymer of polyethylene napthalate comprising at least about 51% dimethyl-2,6-naphthalene-dicarboxylate as an acid component and 49% or less of another acid component, said refillable container being capable of undergoing multiple trips through a washing, filling, shipping and consumer use cycle, and said base of said container being oriented and having sufficient impact resistance so that said container will not break when dropped one meter onto a concrete surface when filled with water at both 4.4.degree. C. and 22.2.degree. C., said base of said container being oriented by the process of blow-molding a preform wherein the preform stretch ratio is in the range of 5 to 9.
A pourable, hot wash, refillable container comprising a base, a cylindrical body having an average wall thickness of at least 0.635 mm, a shoulder portion, and a neck portion, said pourable, hot wash, refillable container being composed of a copolymer of polyethylene napthalate comprising at least about 97% dimethyl-2,6-naphthalene-dicarboxylate as an acid component and 3% or less of another acid component, said refillable container being capable of undergoing multiple trips through a washing, filling, shipping and consumer use cycle, and said base of said container being oriented and having sufficient impact resistance so that said container will not break when dropped one meter onto a concrete surface when filled with water at both 4.4.degree. C. and 22.2.degree. C., said base of said container being oriented by the process of blow-molding a preform wherein the preform stretch ratio is in the range of 5 to 9.
