A method and apparatus for formation, filling, and sealing unit dose packages for consumer products are described herein. A filling system with a filling control system is also disclosed. Although the filling system is described in conjunction with a method for forming, filling, and sealing unit dose packages, the filling system and filling control system can be used in other dispensing processes.

A method of forming a blow molded container in the form of a tub, the method comprising the steps of: providing an injection molded preform composed of a biaxially-orientable thermoplastic material, the preform being substantially planar; heating the preform; and stretch blow molding the heated preform within a mold cavity to form a tub having a bottom wall and an annular sidewall having an upper edge, the tub comprising biaxially oriented thermoplastic material in the annular sidewall and at least an outer portion of the bottom wall, the stretch blow molding step using at least one stretch rod to engage an inner side of the preform and axially to stretch at least a part of the preform prior to blowing a pressurized gas against the inner side which urges the opposite side of the preform radially outwardly against the mold.

A deep-drawn paper tray made of paper material, a method and an apparatus for manufacturing the tray, and a closed product package comprising the tray. The tray having a bottom and upwardly expanding side walls around the bottom, the side walls of the tray being shaped to expand through a plurality of circumferential steps dimensioned low enough for obtaining wrinkle-free side walls for the tray. The outermost step is a flat, wrinkle-free rim flange, which enables liquid and gas proof heat-sealing of a lid to form the package. The apparatus may comprise upper and lower moulding tools with concentric movable frames for forming the tray bottom and side wall steps from paper blanks, and moulding tools may be mounted onto a rotating turret carrying a paper blank through working stations arranged along the turret circumference, to shape the tray bottom and the side wall steps at the consecutive stations.

A method for thermoforming an article includes extruding a sheet of material, conditioning the sheet with a roller, thermoforming the sheet to provide a web, and cutting the web to provide the article.

Disclosed herein is a polarized lens film production apparatus, which may include a cover part which is configured in a circular plate; a heater part which is disposed at an inner center part of the cover part; a body part which is formed in a cylindrical shape having an accommodation space; a center part which is disposed at an inner center portion of the body part; a plurality of connection pipe parts which are disposed at a side surface of the center part and are connected communicating with the center part; a plurality of dish-shaped forming frames which are disposed at the top of each of the connection pipe part; and a vacuum hole which is defined at a center portion of each of the dish-shaped forming frames and communicates with the connection pipe part, by means of which mass production is available.

A method for imparting textures of grained or woven patterns to the surfaces of thermoset articles during the formation of the article includes a platen with a texture being introduced into a mold. A thermoset material is charged into the mold. Pressure and heat are applied to bring the thermoset material into contact with the platen to impart the texture to a surface of the thermoset material. The thermoset material is allowed to cure in the mold. The thermoset article is removed from the mold with the texture. The textured article is structurally improved relative to a like article formed with a smooth or other platen texture. A system for producing the article by way of the method is also provided.

A method for the crystallization of a film made of a thermoplastic film material, in particular a CPET material, to form a product in which a crystallization process is initiated by shaping the thermoplastic film material within a molding tool. A main crystallization of the crystallization process is carried on outside of the molding tool.

A method is described. The method is a continuous manufacturing method of an acoustic transmission loss panel resonator core. The acoustic panel is a double-wall panel construction with two sidewall panels and a resonator core. The resonator core is formed from a roll of film. One or more rollers form interconnected resonator chambers in the film. The resonator chambers are in a rectangular lattice shape. The resonator chambers are continuously formed from a single sheet and then bonded to the second sidewall. The resonator core is then attached between first and second sidewalls. The resonator core defines an air gap between the resonator core and the first sidewall.

A deep-drawn paper tray made of paper material, a method and an apparatus for manufacturing the tray, and a closed product package comprising the tray. The tray having a bottom and upwardly expanding side walls around the bottom, the side walls of the tray being shaped to expand through a plurality of circumferential steps dimensioned low enough for obtaining wrinkle-free side walls for the tray. The outermost step is a flat, wrinkle-free rim flange, which enables liquid and gas proof heat-sealing of a lid to form the package. The apparatus may comprise upper and lower moulding tools with concentric movable frames for forming the tray bottom and side wall steps from paper blanks, and moulding tools may be mounted onto a rotating turret carrying a paper blank through working stations arranged along the turret circumference, to shape the tray bottom and the side wall steps at the consecutive stations.
