A method for producing a multiple preform, including a primary injection for injection molding a preform main body using a primary mold, and a secondary injection for injection molding, using a secondary mold, a covering layer that covers the preform main body such that the terminal end side of the covering layer covers the lower surface of the neck ring and reaches the peripheral edge of the neck ring. A projection strip portion is formed when the preform main body is inserted into the secondary mold to be clamped, that projects in a gap in which the covering layer is molded to be in contact with or adjacent to a lower surface of the neck ring, and that extends with a given length along an axis direction, is formed on an inner peripheral surface of the secondary molding mold, thereby forming an easy tear portion in the covering layer.

Article having a body portion including one or more walls surrounding an interior space. The one or more walls have an inner surface, an outer surface, a wall thickness, a transparent portion, and one or more aesthetic regions having oblong voids provided between the inner surface and the outer surface within an outermost 70% of the wall, and the one or more aesthetic regions are provided in a predetermined pattern.

A method for manufacturing a container includes injecting a first material into a first mold to form a top portion of a preform. The first material and a second material are injected into the first mold to form a bottom portion of the preform. The preform is disposed in a second mold. The preform is blow molded into a finished container.

A system for molding an object includes an articulated mold having an axis and a plurality of mold portions configured to collectively define a molding cavity for shaping the object when arranged in respective molding positions. The system includes a plurality of actuators, each operatively coupled to a respective mold portion and configured to move the respective mold portion along the axis from the respective molding position toward a respective ejecting position for releasing the object. The system includes a controller in communication with each of the plurality of actuators and configured to independently activate each of the plurality of actuators such that one of the plurality of mold portions moves along the axis from the respective molding position toward the respective ejecting position while at least one other of the plurality of mold portions remains stationary relative to the object in order to at least partially support the object.

A manufacturing method of a resin container includes: a first injection molding process for injection-molding a first layer of a preform by using a first resin material, the preform having a bottomed cylindrical shape and including a groove that extends in an axis direction; a second injection molding process for injecting a second resin material into the groove of the first layer, the second resin material having a color that is different from a color of the first resin material, and laminating a second layer on an outer peripheral side or an inner peripheral side of the first layer; and a blow-molding process for blow-molding a preform that includes multiple layers and has been obtained in the second injection molding process in a state where residual heat at a time of injection molding is contained, and manufacturing the resin container having a vertical-striped color pattern formed by using the second layer.

This method for manufacturing a resin container includes injection molding a plurality of preforms in an arrangement direction, a adjusting the temperature of the preforms, and molding containers from the preforms. The manufacturing method includes, between the injection molding and the temperature adjusting, changing the orientation of the preforms aligned in the arrangement direction to an orientation aligned in a conveying direction.

A system for forming a container includes an injection station configured to inject a liquid material into a mold to form a preform. The system also includes a forming station including an apparatus for forming a container. The apparatus includes a blow mold configured to receive the preform and inject air into the preform to form the container. The blow mold includes an inner mold surface. The apparatus also includes at least one stretching rod configured to contact the preform in the blow mold and stretch the preform. The apparatus further includes electric heating elements coupled to the blow mold and positioned adjacent the inner mold surface to heat the inner mold surface. The system further includes a removal station configured to release the container from the system.

Disclosed herein, amongst other things, is a molded article, such as a preform that is blow moldable to form a container, and a related method of forming and recycling a container. The structure and steps includes injection molding a molded article having tubular body.

A bottle for containing an item, generally a pharmaceutical product, wherein the bottle includes a body having a bottom wall and sidewalls, a neck extending from a top portion of the sidewalls and a thread defined on the neck. The neck defining a mouth of the bottle, an internal surface and an external surface. A neck thickness is defined between the internal surface and the external surface. The thread defines a thread thickness. The thread thickness is substantially the same as the neck thickness.

Provided is a method for manufacturing a preform (1). The method includes injecting into a cavity of a mold through the gate: (i) a first colored resin (R1) for a first predetermined time period, and (ii) a second colored resin (R2), having a color different from that of the first colored resin, for a second predetermined time period.
