  • Patent number: 9669569
    Abstract: The invention relates mold, particularly a mold for producing foam articles. In a preferred embodiment, the mold comprises a lid and a bowl releasingly engageable to define a mold cavity, the lid comprising: (i) a vent having a passageway for gas to escape from the mold cavity, and (ii) a plurality of grooves connected to the vent. The use of a plurality of grooves/slots in the mold cavity surface effectively acts as a siphon to draw gas away from the composition to be molded. The plurality of grooves/slots is connected to one or more vents which then allows for escape of the gas from the mold cavity to the exterior of the mold.

  • Publication number: 20150028650
    Abstract: There is described a padded element comprising a foam substrate having disposed therein a first internal surface and a second internal surface opposed to the first internal surface, the first internal surface being interposed between an outer surface of the foam substrate and the second internal surface, at least one of the first internal surface and the second internal surface comprising a textured portion. In a highly preferred embodiment, the pair of internal surfaces disposed within the body of the foam substrate combine to form one or more cavities in the foam substrate (e.g., by the provision of one internal surface have a textured portion and the other internal surface being untextured). The provision of such a textured surface creates a contacting interface (either at rest or when an occupant sits on the seat) between below or remote from the A-surface of the foam element. This interface has different properties than the exposed surface of the seating element.
