摘要:
A dimensionally-stable, injection-molded portion of a blow molded intermediate article is engaged by a conveyance mechanism of a trimmer to controllably drive the intermediate article within the trimmer to permit accurate and high speed severing of the injection molded portion and moil from a blown finish container body. An injection-molded, closed end preform is provided having a neck finish with an internal and/or external peripheral drive surface. The preform is utilized to form an intermediate article including a container body and moil. The injection-molded neck portion of the intermediate article remains substantially unchanged from its as-manufactured preform condition and provides a dimensionally stable surface for use in driving and rotating the intermediate article within the trimmer.

An inventive orientation apparatus is provided in the present invention preferably for use with blow molding operations. The apparatus includes an object having a body portion and a neck portion. The neck portion has an outer peripheral surface and an alignment lug which extends outwardly from the peripheral surface and past the same. Additionally, a rotating support is included for supporting the object and causing the same to rotate, wherein the rotating support is movable with a moving carrier pallet. The apparatus also includes an orientating element located adjacent the carrier which engages the alignment lug on the object and stops the rotation of the object at a desired orientation. The invention may also include an orientation check device which is positioned upstream from the orientation element, adjacent the carrier, which is used for checking the orientation of the alignment lug for preventing a system jam.

Multi-barrier bottles having tabbed preforms, as well as methods of forming the same are disclosed. A tabbed preform includes an elongate body extending into a cavity of a first barrier, where the cavity is defined by at least one piece having a recess therein. The tabbed preform further includes at least one preform extension piece extending from the elongate body at a predetermined distance from a top surface of the elongate body. The at least one preform extension piece is sized and shaped to correspond to a size and a shape of the recess.

A particularly small eyedropper or the like is provided, which has a construction such that, when a body thereof is squeezed, an introduction hole thereof can be easily closed to compress air in a space between an inner layer and an outer layer thereof even in the absence of a check valve in the introduction hole, and defectiveness of the introduction hole can be easily checked. To this end, a test hole (19) communicating with an introduction hole (17) via a space between an outer layer bottle. (1) and an inner layer bag (16) is provided in an outer layer mouth portion (4). The test hole (19) is closed by the inner layer bag (16) and an inside plug (21) fitted in the mouth portion (4). Further, the introduction hole (17) is provided in a middle portion of a body which is pressed by a finger when the bottle is squeezed. The introduction hole (17) is closed by the finger.
摘要:
A method for heating a preform that is rotationally symmetric about its longitudinal axis, has a standard thread, and is made of a thermoplastic material. During heating, the preform is temperature conditioned to be formed into a container having a non-circular cross-section transverse to a longitudinal axis of the container by blow-molding. The preform is provided with a temperature profile along a circumference of the preform such that areas of the preform are differentially heated in a radial direction of the circumference of the preform. The standard thread of the preform is aligned in a predefined target position before the areas of the preform are differentially heated. The preform is rotated into alignment. An alignment element engages in the standard thread of the preform and thereby prevents further rotation of the preform as soon as the alignment element comes in contact with a predetermined contact surface in the standard thread.
