A bottle configured to house and dispense items. The bottle comprises a body, a finish positioned above the body, and a ramp protruding into an interior space defined by the body. The body includes a base and a sidewall extending up from the base. The body defines the interior space for housing the items. The finish presents an opening for dispensing the items from the body. The ramp is formed with a concave shape configured to support one or more of the items.

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.

When a hollow molded body using a preform to be molded with a thin bottom portion is produced while taking advantage of the roughening of the outer surface of an injection core mold, transferred roughening marks are prevented from appearing on the bottom portion of hollow molded bodies, so that the hollow molded body with an aesthetic bottom portion is obtained. An injection core mold (12) has an outer surface of its tip portion corresponding to a preform bottom portion (10) and a lower end portion (14a) of a preform body portion (14). The outer surface corresponding to the preform bottom portion (10) and the lower end portion (14a) of the preform body portion (14) is a mirror-finished surface (20), and the outer surface of the injection core mold for forming the preform other than the mirror-finished surface is a roughened surface (15).

A thermoplastic pre-container, typically a blow molded piece, is provided to form several hollow bodies. The pre-container is elongated along a central axis and includes a bottom section, an opened section and in-between at least one hollow body section. A plurality of circumferential grooves are provided in a pre-container sidewall, each with a bottom line formed in a virtual plane perpendicular to the axis. The bodies are obtained after cutting the pre-container in a direction transverse to the central axis and severing the end sections. Due to the cutting at several of the circumferential grooves, a top opening and a base opening are respectively obtained for at least two hollow bodies, each opening being delimited by an annular inner rim of a body flange.

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.

A hollow article is molded in a state where an inner surface of a neck portion including an inner screw portion is held by an inner neck mold, and then, the hollow article is demolded from the inner neck mold by inserting an ejection rod into the hollow article to be engaged with an inner surface of the hollow article and rotating the hollow article together with the ejection rod.

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 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.

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.
