A method for manufacturing a plastic fuel tank including: a) inserting a plastic parison including two distinct parts into an open two-cavity mold; b) inserting a core, bearing at least part of a reinforcing element configured to create a link between the two parison parts, inside the parison; c) pressing the parison firmly against the mold cavities, for example by blowing through the core and/or creating suction behind the cavities; d) fixing the part of the reinforcing element to at least one of the parison parts using the core; e) withdrawing the core; f) closing the mold, bringing its two cavities together to grip the two parison parts around their periphery to weld them together; g) injecting a pressurized fluid into the mold and/or creating a vacuum behind the mold cavities to press the parison firmly against the mold cavities; and h) opening the mold and extracting the tank.

A process of manual, semi-automatic and fully-automated integration of discrete components into a container that results in fast, reliable, cost-effective, and scalable production of composite containers is disclosed. The process can be embodied in manufacturing equipment that has a series of stations and may be called an assembly device. The equipment can produce containers, tubs, canisters, cartridges, etc. which are easily separated into different bio-degradable or compostable parts. Other container types are possible and are contemplated.

The invention relates to a method for producing plastics containers from thermoplastics with inserts which, by exploiting the heat of plasticization, are connected during shaping of the plastics container by a material bond and/or interlocking connection to the container wall, wherein the method provides the use of at least one opening on the insert, which opening forms a melt duct or melt inlet and/or melt passage for plasticized or plastic material of the container wall, wherein the method is distinguished in that the opening is monitored as a reference opening by optical and/or sensory means during the production of the connection, wherein the degree of penetration of the opening with thermoplastic from the container wall is used as a measure of the quality of the connection.

A free-standing plastic livestock confinement system includes hollow plastic panels assembled together to provide interconnected walls that create confinement areas. One of the walls provides a door opening and a door that can be closed across the opening. The door is a hollow plastic panel with an opening for an animal to place its head through for access to food. The door is molded with a bucket holder and the opening in the door over the bucket holder. The bucket holder is recessed such that a bucket received in the bucket holder will extend partially into the confinement area.

A copolymer of propylene with hexene-1 containing from 5 to 9% by weight of recurring units derived from hexene-1, having a melting temperature from 125 to 140 and Melt Flow Rate (ASTM D1238, 230/2.16 Kg) from 0.1 to 3 g/10 min., is used to produce blown films having valuable mechanical and optical properties.

A process for manufacturing a plastic hollow body including extruding a molten plastic parison through a die. At least one longitudinal cut is made in the parison. The parison is introduced into a mold comprising two cavities. The hollow body is molded by conforming the parison to the mold cavities. The die includes a passage for the molten plastic which gradually modifies the shape of the parison so that it is substantially flattened on exiting.

This application belongs to the field of methods of forming animal decoys for outdoor usage. The decoys include a main body, which is made of ethylene vinyl acetate material and is collapsible. The main body is made from two sheets of ethylene vinyl acetate material with edges which are attached to each other. At the bottom of the main body, there is a hole to allow air flow.

A copolymer of propylene with hexene-1 containing from 5 to 9% by weight of recurring units derived from hexene-1, having a melting temperature from 125 C. to 140 C. and Melt Flow Rate (ASTM D1238, 230 C./2.16 Kg) from 0.1 to 3 g/10 min., is used to produce blown films having valuable mechanical and optical properties.

An indoor livestock confinement system includes a plurality of hollow plastic panels. One of the hollow plastic panels defines a U-shaped door frame. The door frame is open at the top and includes an attachment for a door at one edge. The door frame includes a reinforcement inside the panel that extends across a bottom threshold and sides of the door frame.

A container obtained by blow-moulding a rolled tube. The container includes a body extending, according to a longitudinal axis, between a bottom and a neck made integrally in one-piece with the body. The body has, along a height according to the longitudinal axis, a wall having a thickness between 0.05 mm and 0.4 mm. The neck has, along the height according to the longitudinal axis, a wall having a thickness between 0.4 mm and 0.8 mm.
