摘要： A method for saturating a thermoplastic polymer material includes continuously moving the polymer material through a pressurized pressure vessel. To do this, the method includes sealing the pressure vessel with a series of dynamic seals that allows the polymer material to continuously move through the pressure vessel while maintaining the pressure inside the pressure vessel.

摘要： A method for generating a microstructure that includes microcellular bubbles, in a material that includes molecules of a thermoplastic polymer, comprises: determining a size-index for the material that represents an average size of the thermoplastic polymer molecules included in the material, and in response to the determined size-index, setting a parameter of a process to generate a microstructure in the material that includes microcellular bubbles. The process to generate a microstructure in the material includes: 1) infusing into the material, during a first period, a gas that does not react with the material, 2) making the gas-infused material thermodynamically unstable.

摘要： A double-walled container including an inner sleeve, an outer sleeve and a base is provided. The inner sleeve is positioned within the outer sleeve. A sidewall cavity may be formed between an inner sleeve sidewall and an outer sleeve sidewall. The lower end of the outer sleeve forms an elongated loop located below a lowermost edge of the inner sleeve. A flange may extend from the elongated loop upwardly above the lowermost edge of the inner sleeve and is attached to the inner sleeve. The elongated loop may form a loop cavity. The loop cavity may be in fluid communication with the sidewall cavity.

摘要： A container for holding food items and the like. The container comprises a base for holding the food item and a cover hingedly mounted to the base and movable between an open and closed position. The cover has a latch wipe opening that is sized to receive a tab extending from the base. The latch wipe opening has a generally rectangular shape. During the manufacturing process, the material in which the latch wipe opening is formed is pre-cooled to reduce the tendency of the latch wipe opening to deform. Further, the form against which the latch wipe opening is formed has a knurled portion that engages the container material above the latch wipe opening to further prevent the deforming of the latch wipe opening during manufacturing.

摘要： A paperboard blank stacker assembly for supplying a stack of paperboard blanks to a container forming machine includes a stacker. The stacker has multiple blank stops arranged to hold a peripheral edge of a bottom blank of the stack of paperboard blanks, with the multiple blank stops defining an interior region. A blank carrier has at least one suction device moveable into a grasp position, where the suction device applies a suction force to the bottom blank, and a removal position, where the suction device is moved to remove the bottom blank from the stack of paperboard blanks by pulling the bottom blank through the interior region.
