Abstract
A method of producing a container and a closure comprises blow molding a body comprising a container portion and a closure portion joined together, and separating the closure portion from the container portion. A container and/or a closure produced according to the method are also disclosed, as well as an intermediate product for producing a container and a closure.
Claims25
An intermediate product for making a container comprising:
- a blow-molded single-piece hollow body comprising a container portion, a closure portion and a central moil portion disposed between the container portion and the closure portion;
- the container portion includes a mouth, a bottom, and a container central axis extending through a center of the mouth and the bottom;
- the closure portion includes a perimeter defining a cavity having an open end, a closed end, and a closure central axis extending through a center of the open end and the closed end, wherein the closure central axis is aligned parallel with the container central axis;
- and
- the central moil portion includes an upper section proximate the closure portion, a lower section proximate the container portion, and a midsection between the upper section and lower section, the midsection having a cross-dimension in plan view smaller than either the upper section or lower section,
- wherein the perimeter of the closure portion is configured for mating engagement about the mouth of the container portion when the central moil portion is removed.
