A molding-forming method, a molding mold, and a molding production apparatus with which efficient burrs removal is possible without requiring a large apparatus. A molding production method includes, in addition to a molding being formed inside a mold, burrs formed around the molding are separated from the molding. After formation of the molding, air is blown inside the mold on at least a portion of the burrs formed around the molding to cool the same, a projecting member is projected toward the cooled burrs, and the burrs are separated from the molding. After pressing the burrs toward the projecting member by the air blowing, the burr is pressed toward the mold surface facing the projecting member by projection of the projecting member to separate the burr from the molding.

The disclosed method may include bending, by an end-shaping tool, a portion of an end of a strap in a direction at least substantially perpendicular to a plane of the strap. The bending may include extending the portion of the end of the strap over a raised area of a first portion of the end-shaping tool and connecting a second portion of the end-shaping tool to the first portion. The connecting may include placing a recessed area of the second portion over the raised area of the first portion. The method may include debossing, by an end-setting tool dimensioned to accommodate the strap as bent by the end-shaping tool, the portion of the end of the strap at the bend. Various other methods, systems, and apparatus are also disclosed.

A multiple-chamber container that is extrusion blow molded with a single neck finish and a method to trim the single neck finish is provided. The physical appearance of the multiple-chamber container before the trimming process differs from the multiple-chamber container after the trimming process. The multiple-chamber container includes multiple openings that are configured to engage with a single cap after the trimming process to create a seal. The multiple-chamber container may contain different materials, such as liquids, gel-like substances, granular materials, food, etc. that are not permitted to flow from one chamber to the other chamber when the cap is engaged with the chamber openings.

A tool case with single and double wall sections, the double wall sections extend from one edge or from a corner of part of the case and are defined by a cut line, the cut line changes in height as the double wall sections have contours to conform to the tool to be held. The double wall sections may include supporting portions which are sections where the inner surfaces of the two walls are fused or welded together to create a support which transfers load from the tool between the two walls of the double wall section. In certain aspects, the cut line defines a large internal area of single wall as compared to the overall perimeter of the case or case half.

A method for blow molding a plastic tank from thermoplastic material, wherein the plastic tank is provided with at least one connection element penetrating the wall of the plastic tank while the plastic tank is being shaped within a blow molding tool. The connection element is fitted onto a blowing needle of the blow molding tool and is positioned in the wall by punching in the blowing needle. Also disclosed is a blow molding tool for use in the method having a blowing needle formed to fit a connection element.

A blow-molded lamination container includes an outer layer and an inner layer. The outer layer has a bottom and an air-inletting seam. The air-inletting seam is disposed through the bottom of the outer layer, and is formed from a tapering opening by cooling shrinkage. The inner layer is disposed in the outer layer, is capable of being filled with a content and contracts with respect to the outer layer, and is not nipped within the air-inletting seam by the outer layer. A width of a widest portion of the air-inletting seam is at least twice greater than a width of a narrowest portion of the air-inletting seam. A manufacturing method for the blow-molded lamination container is also provided.
