10464236 · 2019-11-05 · ·

The invention relates to a device for heating preform bodies or flat or preformed semi-finished products from thermoplastic material (3), comprising at least one base body (1.0, 2.0), on the surface of which at least a first layer or coating is formed, which comprises at least one electric heating resistor in the form of a flat, geometrically arranged conductor loop. The base body also has contact elements, by which the at least one heating resistor can be connected to a power source, wherein, as a result of the geometrically arranged conductor loop(s), a defined temperature profile can be generated, which can be transmitted contactlessly to the preform body or the semi-finished product by an outer contact layer formed on the first layer or coating, by contact the surface of a preform body or semi-finished product and/or by using convection or thermal radiation. During a transmission of the defined temperature profile, the preform body or the semi-finished product is arranged at a distance to the contact layer(s).

Fabric-based items with three-dimensional shapes
10286636 · 2019-05-14 · ·

A fabric-based item may be vacuum-formed into a three-dimensional shape. The fabric-based item may include one or more layers of fabric and one more polymer layers that can be molded when heated. To vacuum-form the fabric-based item into a three-dimensional shape, the fabric based item may be heated until the polymer layer reaches a forming temperature and becomes soft and pliable. When heated, a vacuum tool is used to pull the fabric-based item onto a mold so that the fabric-based item conforms to the shape of the mold. As the fabric-based item cools on the mold, the polymer material hardens into the shape imparted by the mold. The polymer material is able to hold the fabric layers in this shape after the layers are removed from the mold.

APPARATUS AND METHODS FOR SELECTIVE THERMOFORMING
20190105828 · 2019-04-11 ·

Apparatus and methods of forming selected portions of integral sheets of material are disclosed. Unformed portions of the sheets may remain undistorted during the forming process, allowing them to contain text, art work, or other desired information without material risk of the information being degraded or becoming unintelligible during the forming process. This result may be accomplished, moreover, with less trim than usually occurs in conventional forming processes.

Blow moulded container and manufacture thereof
10239250 · 2019-03-26 · ·

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.

CONTAINER WITH PRODUCT VISUALIZATION APERTURE
20240227313 · 2024-07-11 ·

The present invention relates to a method for providing a product viewing window in a container. The container has at least a body ply and a liner ply, wherein the body ply has at least one aperture therethrough. The liner ply is adhered to the inner surface of the body ply and has a portion extending across the aperture, forming a window into the container. The method involves providing a window-finishing machine that comprises at least two platens and, optionally, a machine pocket positioned between them, a heating element extending through at least one of the platens, and a pressurized air device that is adapted to release pressurized air into the container through at least one of the platens. The container is engaged between the platens in an airtight manner and, optionally, the container window is positioned adjacent the inside wall of the machine pocket. The heating element heats the window of the container to the desired temperature, pressurized air is injected into the container such that the window is forced at least partially through the aperture of the container (and optionally into contact with the machine pocket wall), and the container window is then cooled to the desired temperature.

Method for the production and filling of an application package for a liquid pharmaceutical product

A method for the production and filling of an application package for a liquid pharmaceutical product. A thermoforming film made of thermoplastics laminated together is heated in order to plasticize the thermoforming film at least in partial areas. The plasticized areas are thermoformed in a mold in order to form a chamber for the liquid pharmaceutical product and a tube-shaped application duct opening into this chamber, with the chamber and the application duct being enclosed by a non-thermoformed, essentially flat bonding area of the thermoforming film. The liquid pharmaceutical product is filled into the chamber, and the chamber and the application duct are sealed by covering the thermoformed and filled thermoforming film with an essentially flat covering film. The covering film is directly bonded to the bonding area of the thermoforming film by thermal ring sealing, enclosing the chamber and the application duct.
