摘要： A very thin inner layer composed of a polymer chosen for its barrier and/or inertness properties is fabricated within a container preform constructed mainly from another polymer, or a structure of polymers. The inner layer on the preform is produced either by a controlled coating method involving coating of the injection mold core rod prior to injection molding or by a coating applied directly to the preform after injection molding. This enables both inner and main layers to be brought together at a time when the interface between them is molten. A tie layer can be employed, when desirable, to enable the layers to be combined without melting the layer interface.

摘要： A squeezable container for dispensing a product out the open end of the container, including a collapsible inner layer and a resilient outer layer. The container is an integral body formed by expansion from a multi-layer preform, and preferably consists of one or more layers of polyethylene terephthalate (PET) separated by an adjacent boundary layer, such as a barrier layer of ethylene vinyl alcohol (EVOH). A one-way check valve is provided at the outer layer to restrict the flow of air into a chamber which is formed between the inner and outer layers as the inner layer collapses, and preferably a second check valve is provided in the open dispensing end of the container to prevent air from being drawn into the container when the outer layer is released. The container is economical to manufacture, light in weight, easy to handle, can be made of recycled materials, and is "product efficient" in that substantially all of the product can be dispensed from the container during use.

摘要： A plastic preform from which a plastic container is blow molded. The preform replaces a three layer preform by providing a preform which is of a five layer construction in the base forming portion thereof and wherein a secondary material which forms the core layer of the three layer preform construction is divided into an inner intermediate layer and an outer intermediate layer by a third injection of material. The third injected material is preferably the same material as the primary material which is first injected. This results in the reduction of the cost of the preform and also provides remaining in the injection nozzle a quantity of the last injected material which is the same as the first injected material for the following preform in the same preform injection mold cavity.

摘要： An injection molding process for making a multiple layer, plastic structure. A plastic sleeve is placed and then enclosed in a mold cavity. A flowing heated plastic is conducted into the mold cavity, radially inside the sleeve, and forced radially outward against the sleeve. The flowing plastic forces the sleeve outward and forms, with the sleeve, an integrally bonded laminated structure. The mold is opened and the plastic structure is removed, and this structure may then be reformed to form a container particularly suitable for containing beverages, foods, cosmetics, pharmaceuticals and chemicals.
