A foam twin-sheet formed air filled gasket is provided. The foam sheets need not be covered with one or more layers of air impermeable materials before, during or after the twin-sheet forming process. Methods for manufacturing the air filled gaskets are also disclosed.

A method of manufacturing a structure is provided in which a burr portion can be more reliably cut. In a burr portion shaping step, the burr portion is sucked to an engaging portion by a suction part to shape the burr portion along the engaging portion, and in a cutting step, ae movable portion is moved relative to first and second split molds with the burr portion being shaped along the engaging portion, thereby the burr portion is cut from a molded main body along a cutting line.

A foam twin-sheet formed air filled gasket is provided. The foam sheets need not be covered with one or more layers of air impermeable materials before, during or after the twin-sheet forming process. Methods for manufacturing the air filled gaskets are also disclosed.

Disclosed are devices, systems, apparatuses, methods, products, and other implementations of vapor pressure solids. In some embodiments, a vapor pressure solid may include a one- or multi-component matrix material. In some embodiments, the multi-components matrix material is a two-part PDMS comprising a first and second matrix material. The first matrix material is capable of being mixed with one or more vaporizable fluids that causes the first matrix material to swell. The second matrix material is capable of being mixed with the swelled first matrix material to produce an actuating material. When the actuating material is heated, the one or more vaporizable fluids expand, resulting in vapors. The increased pressure applied by the vapors causes the actuating material to expand.

The present disclosure relates to hot-fillable articles made from multilayered thermoformable film and sheet comprising oxygen scavenger compositions and polyester compositions and copolyester compositions which comprise residues of terephthalic acid, 1,4-cyclohexanedimethanol (CHDM), 2,2,4,4-tetramethyl-1,3-cyclobutanediol (TMCD), ethylene glycol (EG), and diethylene glycol (DEG), in certain compositional ranges having certain advantages and improved performance properties.

A method for making a structural sandwich panel includes the steps of positioning a first and second thermoplastic skin elements in overlying relationship with respect to a heated male and heated female die molds respectively. A first pressure reduction is applied between the first thermoplastic skin element and the heated male die mold and a second pressure reduction is applied between the second thermoplastic and the heated female die mold. A core panel element is positioned between the heated male die mold and the heated female die mold wherein the core panel element has a first adhesive on a first side and has a second adhesive on a second opposing side. The male and female die molds are closed and exert a pressure onto the core panel element to secure the first and second thermoplastic skin elements to the core panel element and form the core panel element.

A corrugated plastic box and a method for manufacturing a corrugated plastic box from a blank are provided. The method includes the steps of forming rounded edge seals on the perimeter edges of the blank, pre-sealing portions of the blankincluding providing air vents to allow trapped air to escape during the pre-sealing processto form a plurality of areas in which major and minor flap slots and a glue tab are desired, ultrasonically scoring the blank to form a plurality of flap score lines, and cutting the blank through the plurality of pre-sealed flap slots and glue tab, leaving a sealed edge.

Described are methods of two-dimensionally and three-dimensionally forming an article of wear using vacuum forming in an automated process. In the two-dimensional method, the article of wear comprises a generally flat shape with three-dimensional features molded into the first material layer.

A free-standing plastic livestock confinement system includes hollow plastic panels assembled together to provide interconnected walls that create confinement areas. One of the walls provides a door opening and a door that can be closed across the opening. The door is a hollow plastic panel with an opening for an animal to place its head through for access to food. The door is molded with a bucket holder and the opening in the door over the bucket holder. The bucket holder is recessed such that a bucket received in the bucket holder will extend partially into the confinement area.

An indoor livestock confinement system includes a plurality of hollow plastic panels. One of the hollow plastic panels defines a U-shaped door frame. The door frame is open at the top and includes an attachment for a door at one edge. The door frame includes a reinforcement inside the panel that extends across a bottom threshold and sides of the door frame.
