摘要:
A preform (1) for small flat container formed of a flat core capable of adjusting the limit of wall thickness thereof by reducing the wall thickness of the outer side of a thick-walled shell part formed by stepping up, wherein an inner diameter is formed in a small complete round, a shell part (12) is formed by stepping out to a diameter larger than the diameter of a neck part from a boundary between the neck part (11) and the shell part (12), the outer side of the shell part is formed in an elongated circular shape by reducing wall thickness from the underside of the stepped out part to provide a difference in wall thickness between the forward and backward surface sides (12a) and right and left surface sides (12b) of the shell part (12), and the stepped out part (14) is provided in disk shape on the underside of the neck part.

Processes for obtaining new composite preforms (26) suitable for blow-molding made of at least two different materials (4, 22), preforms obtained thereby, and articles obtained by blow-molding of these preforms. The processes employ the injection-molding of two (or more) plastic materials to form preforms that can be blow-molded into articles. In a preferred embodiment, the two materials have different colors and the resulting articles show a multi-colored effect. The two materials are not laminated over each other.
摘要:
Process for making preforms made of two different materials wherein the first material (4) and the second material (22) are injected with nozzles having center axis that are not coaxial.. Preferably the preforms comprise an inclusion of the second material within the lateral wall of the first material. The new preforms preferably comprises a bottom region (1c) and a lateral wall region (1b), wherein the bottom region is entirely made of the first material and the lateral wall region is generally made of the first material (4) with the exception of at least one volume (14) which is filled by the second material (22).

摘要:
To solve the limit of wall-thickness adjustment of a preform for a small flat container by a flat core by forming the outer side of a step-up-formed large-wall-thickness shell part with reducing wall thickness. A preform 1 for a small flat container whose inside diameter is completely circular and restricted to a small value is used. A shell part 12 is step-out-formed from the boundary between a neck part 11 and a shell part 12 so that the shell part 12 has a diameter larger than the neck part 11. A difference is provided between wall thickness of forward/backward sides 12a and right/left sides 12b of the shell part 12 by forming the outer side of the shell part into an ellipse form or the like from the underside of step-out at with reducing wall thickness. A stepped out part 14 is left like a disk in the underside of the neck part.

Die Erfindung betrifft einen Vorformling (1), insbesondere Hohlkörper - Spritzformling mit einem Halsfortsatz (2) mit einem am Außenumfang (3) des Halsfortsatzes (2) angeordneten Verbindungsmittel (4), z.B. einem Außengewinde (5) und einem mit dem Halsfortsatz (2) einen Übergangsbereich (9) ausbildend angeformten, vom Halsring in Richtung einer Längsmittelachse (10) verjüngt verlaufenden, einen Innenraum (13) begrenzenden Hohlkörperteil. Eine innere Querschnittsfläche (7) des Halsfortsatzes (2) ist gering kleiner als eine von einer Außenfläche (16) im Übergangsbereich (9) umgrenzte Querschnittsfläche (22) und bildet in einem Abstand (20) von der Querschnittsfläche (22), in Richtung einer Länge (15), einen konisch verlaufenden Wandbereich (19) an einem Außenumfang einer Stützfläche (21) aus.
摘要:
A blow-molding method for forming a squeezable or tubular plastic container is provided. The method includes molding a preform having a sidewall, an interior cavity, an open end, a closed end, and a neck adjacent the closed end of the preform. The neck of the preform has an engagement structure. The method includes providing a blow mold system including a blow mold cavity. The method includes placing at least a portion of the preform into the blow mold cavity, and blow molding a one-piece container body from the preform by inflating the preform within the blow mold cavity. The container body has an open end, a closed end and a neck adjacent to the closed end. Wherein the open end of the container body is formed from the open end of the preform, and the closed end of the container body is formed from the closed end of the preform. The method includes creating a dispensing opening through the closed end of the container body.
摘要:
A dunnage platform is in the general shape of a rectangular slab with legs (20-28) extending form one side. The dunnage platform is made from an expanded polystyrene core (10). A chemical combination process is used to chemically combine portion of the core proximal to its surface with high impact polystyrene. In a first of two parts of the combination process, the core is placed in a forming mold (50) with one of its two sides and two thirds of its thickness extending therefrom. A heated sheet (67) of high impact polystyrene is brought into contact with the portion of the core extending from the mold. In a similar manner, the other of the two sides of the core is made to extend from the forming mold for contact with a heated sheet of high impact polystyrene.
