A thermoforming device is described. It relates to a mold assembly including a first and second mold, and to a mold that can be used in a thermoforming device. It also relates to a method for thermoforming a product. The thermoforming device is characterized in that the thermoforming device comprises a second pre-stretcher, in addition to a first pre-stretcher and a calibration element, and that the second pre-stretcher is at least partially and moveably arranged in a second mold body. A movement relative to the second mold body and towards the same forming cavity of the first pre-stretcher, the second pre-stretcher, and the calibration element, can be individually controlled, and the second pre-stretcher at least partially surrounds the first pre-stretcher and the calibration element.

A tray appliance of the present disclosure has a first dissolvable sheet and a first substance formed within a second dissolvable sheet. The first dissolvable sheet is laid on the second dissolvable sheet and is formed into a first dissolvable negative impression of a person's teeth, gingival tissue, or other soft tissue, such that when first dissolvable negative impression is worn by a person, the first dissolvable negative impression dissolves and releases the first substance into the person's saliva, teeth, gingival tissue, or other soft tissue.

There is provided a laminate in which when the protective plate breaks due to an impact, not only the scattering of large broken pieces but the scattering of powdery fine broken pieces can be suppressed. A laminate including an adherend and an adjacent layer, wherein the adherend has a first major surface, a second major surface being a back surface of the first major surface, and a lateral surface connecting an edge of the first major surface and an edge of the second major surface, at least the first major surface and the lateral surface of the adherend are covered with the adjacent layer, the adjacent layer has at least a plastic film and a hard coat layer containing a cured product of a curable resin composition in this order from the adherend side, and a softening point F1 of the plastic film and a softening point F2 of the hard coat layer satisfy a relationship of F1<F2.

A method for making a container, wherein in a positioning step a tray (2) constituted of a single sheet of material, folded and shaped with wrinkled zones (3) is positioned in a thermoforming mould (7), and wherein in a covering step a sheet of thermoplastic material (1) is thermoformed on the tray (2), the covering step being carried out while preventing the thermoforming mould (7) from making contact with the layer of thermoplastic material (9) at the wrinkled zones (3) of an annular flange (6) of the tray (2). Also claimed is an apparatus (13) which comprises a thermoforming mould (7) in which there are present a first peripheral portion (8) configured to support in use the annular flange (6) of the tray (2) and a second peripheral portion (17) which, in the operating position, is facing the first peripheral portion (8), wherein in the operating position, the second peripheral portion (17) is at a distance from the first peripheral portion (8) in such a way that it does not make contact with the layer of thermoplastic material (9) stuck to the tray (2), at the wrinkled zones (3) of the annular flange (6).

A system includes an orientation determination system comprising a camera where the camera is configured to capture an image of an orientation feature of a physical dental model of a dental arch of a customer with material thermoformed thereon. The orientation determination system is configured to identify an offset of the physical dental model with respect to a fixture plate during positioning or before or after the physical dental model is positioned on the fixture plate by determining an actual orientation of the physical dental model based on the orientation feature. The system also includes a laser trimming system configured to cut the material along a trim line based on the identified offset while the fixture plate is moved about at least two axes to produce a dental aligner specific to the customer and being configured to reposition one or more teeth of the customer.

An improved sheet for making a three-dimensional article for holding food, such as a food tray, and a method of making a three-dimensional article. The sheet comprises a substrate and a laminate film. The laminate film may comprise a ceramic film and a copolymer layer. The copolymer layer can repair any cracks that occur in the ceramic film when the sheet is thermoformed. The food tray is considered a single material that is recyclable.
