A synthetic resin container and method for manufacturing the same, including a container main body molded into a predetermined container shape and a covering layer laminated on an outer peripheral surface side of the container main body. The method includes heating the composite preform to bring the covering material layer into a molten state or a semi-molten state while softening the preform main body to be stretchable, subsequently molding the composite preform into a predetermined container shape by using a blow molding die in which an edge portion formed by providing a step on a cavity inner peripheral surface extends along a predetermined direction, and providing, in the covering material layer to be molded integrally with the preform main body, a thin portion molded by being brought into pressure contact with the edge portion.

A blow mold provided with a locking system for mutually locking each half-mold with the related half-mold holder, thus allowing a simpler and quicker replacement of the side half-impressions of the mold. The blow mold of the invention provides for the side half-impression of each half-mold to be fixed in a cavity of the corresponding mold holder by actuating at least one quick coupling device comprising a bar (23) inserted in one of the two longitudinal edges of the half-mold holder (3) and adapted to move only by rotation about an axis thereof; actuation means (22) adapted to actuate a rotation of said bar; and at least one locking fin (21) fixed along said bar (23) and adapted to move, by rotating the bar (23), from an unlocking position to a locking position in which said locking fin interacts with the respective half-mold (2).

A biaxial stretch blow molding device comprises: a first guide shaft 57 which is erected on an upper base 51 and to which a blow core fixing member 54 is slidably coupled; a second guide shaft 67 erected on the stretch rod fixing member 56; a support member 59 fixed to the first guide shaft 57 and provided with a guide hole 68 through which the second guide shaft 67 is slidably inserted; a first drive device 63 that moves the blow core fixing member 54 forward and backward independently of the stretch rod fixing member 56; and a second drive device 70 that moves the stretch rod fixing member 56 forward and backward independently of the blow core fixing member 54.

A system for simultaneously forming and filling a polymeric container with a product. The system includes a mold defining a container profile and a mold vacuum vent extending from the container profile to an upper surface of the mold. A striker plate is secured to the upper surface of the mold. The striker plate defines a striker vacuum vent that aligns with the mold vacuum vent to allow some of the product to be pulled by vacuum out of the mold through the mold vacuum vent and the striker vacuum vent.

A plastic container comprises an upper portion including a finish defining an opening into the container, a lower portion including a base defining a standing surface, a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis, and at least one substantially transversely-oriented pressure panel located in the lower portion. The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position.

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.

Apparatus (1) for forming plastic preforms (10) into plastic containers (20). In a closed state of a blow mould (14), a contact area is formed between side parts (14a, 14b), in which the two side parts (14a, 14b) rest against each other, the side parts (14a, 14b) form a mould separation seam (5) in the contact area. In accordance with the invention, at least one section of at least one side part (14a, 14b) has a coating and/or an additional element (60) in a region of the mould separation seam (5), so that a heat transfer between the plastic preform (10) and the inner wall (52, 54) in the contact area can be delayed at least in places at these at least one section.
