Ways to produce a container (315, 415, 515, 720, 815, 915) having a shaped tail (610, 910) are provided that include blow molding a precursor having a tail (105, 110, 205, 310, 410, 510, 715, 810, 910) and shaping the tail (105, 110, 205, 310, 410, 510, 715, 810, 910) to form the shaped tail (610, 910). Various types of blow molding can employ various types of precursors having tails (510). Injection blow molding can be used where a preform (105, 200, 305, 405, 505) having a tail (105, 110, 205, 310, 410, 510, 715, 810, 910) is optionally longitudinally stretched and is expanded with a gas or a liquid. Extrusion blow molding can be used where a parison (705) having a tail (105, 110, 205, 310, 410, 510, 715, 810, 910) is expanded. A tail (105, 110, 205, 310, 410, 510, 715, 810, 910) shaping means can be part of the blow molding process or can be employed after the container (315, 415, 515, 720, 815, 915) is produced from the precursor having the tail (105, 110, 205, 310, 410, 510, 715, 810, 910). The shaped tail (610, 910) can impart functionality to the container (315, 415, 515, 720, 815, 915), including where the tail (105, 110, 205, 310, 410, 510, 715, 810, 910) is shaped into a coupling point that can serve as an attachment point, hanging point, or hook, for example.

A mold for temperature adjustment including a plurality of temperature adjustment blocks aligned in an upper and lower direction. An insulation mechanism is provided at an uppermost stage of the temperature adjustment block.

A preform made from two different materials that do not bond together by a bi-injection process, using the same mold, is presented. An outer layer of the preform can be first made, then an inner layer molded through a center hole in a bottom of the outer layer, and the two layers connected. Inner/outer preform materials can be different, such as PET/polyolefin or polyamide, or the same, such as PET/PET. To prevent mutual bonding during molding of the second layer, a non-stick coating may be sprayed onto a surface portion of the first layer prior to molding the second. In embodiments, manufacturing order can be either outer/inner, or inner/outer, and the non-stick coating sprayed on the inside/outside of the layer first molded.

A method of producing a resin container includes injection-molding a resin intermediate molded body of bottomed cylindrical shape as a first injection-molding, injection-molding a resin material outside the intermediate molded body as a second injection-molding, to produce a multilayer preform in which a resin layer is layered on an outer peripheral side of the intermediate molded body, and blow-molding the preform in a state of containing residual heat from injection-molding to produce a resin container having a bottom portion thicker in wall thickness than a body portion. A portion of the inner peripheral side of the intermediate molded body, the portion reaching a bottom portion of the intermediate molded body, has a tapered region in which the wall thickness increases toward the bottom portion.

Provided is a container preform made of plastics material having a body exhibiting symmetry of revolution about a central axis and a bottom closing the body from one of its ends. The bottom has an annular bead forming a standing plane of the preform, and the bottom has an external skin oriented toward the outside of the preform and an internal skin oriented toward the inside of the preform. At least one of the internal skin and the external skin has, radially from the central axis as far as the annular bead, a profile having a break in curvature.

A preform is made of a thermoplastic material and is used to manufacture blow-molded containers. The preform has a tube-like central area, a closed bottom and a mouth section. The mouth section lies opposite the bottom in the direction of a longitudinal axis and defines an interior space. The wall thickness in the area of the bottom is at least partially smaller than in the central area. In the region of an inner or outer surface, the bottom has at least one protrusion and optionally a web. The axial web extends from a center of the bottom in the direction of the central area. The vertical web can connect at least two axial webs with each other or be designed alone. The protrusion and the optional webs are formed by a melting chamber and flow channels following the material feed via the sprue.

A container includes a flat foot base having a gate centered on a central axis of the container and a sidewall connected to the base and defining a portion of an interior of the container. A plurality of strap ribs are positioned in the base, each one of which extends radially outward toward the sidewall. A plurality of recessed columns are positioned in the sidewall and formed from varying depth sidewall ribs extending along a periphery of the sidewall. Each varying depth rib includes shallow sections and deep sections, the shallow sections having a rib depth less than a rib depth of the deep sections. The shallow sections of the varying depth ribs are aligned to form the recessed columns. At least one strap rib is aligned with at least one recessed column.

A parison configured to be injection blow molded into a container, and a method therefor. A distal end of the parison is configured to be blown into a container base including an inner surface defining a lower end of the internal volume. The inner surface slopes downward from a sidewall to a radial center of the base such that the radial center is at a lowermost portion of the inner surface of the base, and the inner surface provides a funnel directing contents of the internal volume down to the radial center. An annular flange at a distal end of the parison is configured to be injection blow molded into a standing ring of the container. The parison is configured to form by injection blow molding the standing ring, the inner surface of the base, the container body, and the finish to be monolithic.
