An expansion device, including: an irradiation unit configured to irradiate the thermally expandable sheet placed on a placing unit with light; a conveyance unit configured to reciprocably convey the irradiation unit between a first position and a second position; an exhaust fan fixed to a housing and configured to discharge air from the housing; and an air supply fan which is movable with the irradiation unit and configured to supply outside air into the housing, wherein the exhaust fan is provided at a position where air can be discharged from the second position side when the irradiation unit is returned from the first position to the second position after being moved from the second position toward the first position.

A transfer sheet includes a cured liquid crystal composition layer, a block layer including a (meth)acrylic polymer, and a thermoplastic welded layer in this order, the thermoplastic welded layer and the block layer are in direct contact with each other, and the thermoplastic welded layer includes a thermoplastic resin and an ultraviolet curable resin.

Tabbed sealing members with a robust tab structure having additional support under the tab and at a tab pivot or hinge joint.

The invention covers a method of producing a heat-resistant polymer-coated oven board, the resulting oven board, a food tray and a food package, which comprise such board and withstand heating in a range or microwave oven. According to the invention the coated oven board (1) is made by adhering a premade heat-resisting film (4) comprising polyethylene terephthalate (PET) or its derivate, such as glycol-modified PET known as PETG, to a board base (2) by extrusion lamination, in which an adhesive layer (3) comprising polyamide (PA) is extruded between the heat-resisting film and the board base. To improve the strength and barrier properties, the film (4) may be an extruded multilayer film and/or the film may be stretch-orientated to bring about crystallization in PET.

A thermally expandable sheet includes: a first thermally expansive layer that is formed on one side of a base and contains a first thermally expandable material and a first binder, the first thermally expansive layer having a first ratio of the first thermally expandable material with respect to the first binder; and a second thermally expansive layer that is formed on the first thermally expansive layer and contains a second thermally expandable material and a second binder, the second thermally expansive layer having a second ratio of the second thermally expandable material with respect to the second binder, wherein the first ratio is lower than the second ratio.

Container having a body and a bottom that together delimit an internal primary volume of the container, this container also comprising a protruding base comprising an outer wall and an inner wall, the base comprising a skirt which protrudes from the region of the join between the body and the bottom, and a foot which lies at a lower end of the skirt and defines a setting-down plane for the container, in which container: the walls are locally welded together in the region of the skirt; the foot forms a hollow bulge, and the outer wall, the inner wall and the setting-down plane together define a secondary volume isolated from the primary volume by the weld.

A laminated structure has a first layer formed from a fiber reinforced plastic, a second layer formed from a fiber reinforced plastic and arranged opposed to the first layer, a first core layer formed from a first resin foam and arranged between the first layer and the second layer, and a second core layer formed from a second resin foam and arranged between the first core later and the second layer. The first resin foam has a higher flame resistance than the second resin foam. A laminated structure having flame resistance and high strength enough to endure a bird strike or the like at the same time can be manufactured at relatively low manufacturing cost.

The inventors have discovered that certain hot melt adhesives can be used to form a stable stacked pallet that can limit the need for additional packaging materials e.g. inter-layer and pallet wrap.

A display device includes a window member and a display module coupled to the window member. The window member includes a first resin layer and a second resin layer. The first resin layer is on the display module and has a first elongation, a first thickness, and a first hardness. The second resin layer is on the display module and the first resin layer and has a second elongation smaller than the first elongation, a second thickness greater than the first thickness, and a second hardness greater than the first hardness.
