A manufacturing method includes an injection molding process of injection-molding a preform having a two-layer structure including an outer layer preform and an inner layer preform, and a blow molding process of blow molding the preform to mold a delamination container made of resin. The injection molding process includes an outer layer molding process of filling an outer layer injection mold with PET (outer layer resin material) to mold the outer layer preform and molding a thin film portion in a part of the outer layer preform, and an inner layer molding process of injecting PP (inner layer resin material) toward the thin film portion to break the thin film portion and filling an inner layer injection mold with PP having a temperature lower than a melting point of PET via the broken thin film portion to mold the inner layer preform.

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 dispenser head (100) for dispensing a unit (C) of a pharmaceutical drug or a food supplement or food is provided, said dispenser head (100) comprising: a dosing duct (102) extending along a dosing axis (104) and connecting an inlet port (106) for receiving the unit (C) from a reservoir (11) with an outlet port (108) for dispensing the unit (C); a support section (130) for the unit (C), which extends from the exit port (108) parallel to the dosing axis (104); and a retention section (110), which extends from the support section (130).

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.

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.

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.

A delaminated container has a main body portion and an opening portion. An accommodation space of the delaminated container is formed by a body inner surface of the main body portion and an opening inner surface of the opening portion. The delaminated container includes a first layer and a second layer. The first layer includes a first tightly-attached section. At the main body portion, the first layer is located closer to the body inner surface than the second layer located thereto and is exposed on the body inner surface. The second layer includes a second tightly-attached section. The first tightly-attached section and the second tightly-attached section are tightly attached to each other. The first tightly-attached section and the second tightly-attached section are both located at the opening portion of the delaminated container.
