  • Patent number: 7923087
    Abstract: A dunnage platform is in the general shape of a rectangular slab with legs extending form one side. The dunnage platform is made from an expanded polystyrene core. A chemical combination process is used to chemically combine portion of the core proximal to its surface with high impact polystyrene. In a first of two parts of the combination process, the core is placed in a forming mold with one of its two sides and two thirds of its thickness extending therefrom. A heated sheet of high impact polystyrene is brought into contact with the portion of the core extending from the mold. In a similar manner, the other of the two sides of the core is made to extend from the forming mold for contact with a heated sheet of high impact polystyrene.

  • Publication number: 20110081516
    Abstract: A process for forming plastic articles is described which uses a machine (10) having a pair of hingedly-connected female moulds (12, 14), which can be heated and cooled and which can be clamped together. The process involves placing a plastic particulate material in each mould (12, 14) when they are in an open position and heating the moulds (12, 14) to form a plastic skin (58, 60) lining each mould (12, 14). An expandable filler material (62) is then placed in one mould and the two moulds clamped closed to form a completely closed cavity. The plastic skins in the two moulds bond together to form a continuous plastic shell (66) completely encasing the filler material (62).

    Abstract: There is described a process for adhering a first elongate foam element having a first end portion to a second elongate foam element having a second end portion. The process comprises an initial step of melting a first surface portion of the first end portion to produce a first molten portion. Next the first end portion is abutted to the second end portion. Thereafter, the first molten portion is caused to solidify to create a seam bond between the first end portion and the second end portion. Thus, the present invention relates to adhering two elongate foam elements together at their end portions. The bond between the foam elements is created by melting at least a portion of the surface of one or both of the end portions of the two foam buns. This creates insitu a molten region which acts as an adhesive when the end portions of the two buns are abutted or otherwise contacted with each other.

The polymeric sheet is perforated by one or more fine needles at the blind hole locations. The perforations permit escape of fragrant scent-saturated air to the ambient when pressure is applied to the top surface of the mat. Upon release of pressure, the foam mat and the blind holes recover their shape; the entrapped air pressure decreases, drawing fresh ambient air into the entrapped air spaces.

  • Publication number: 20090181207
    Abstract: A method of making foamed articles that includes providing a copolymer composition, combining the copolymer composition and cellulosic fibers, applying heat, mixing energy and pressure to the copolymer composition and cellulosic fibers mixture to form a foamable mixture, and forming the foamed article by placing the foamable mixture in a molding or extruding operation. The copolymer composition includes a copolymer of 51% to 99.9% of primary monomers, 0.1% to 49% of anhydride containing monomers, and 0% to 25% of other monomers and 0% to 30% of elastomeric polymers. This is combined at 30% to 99.99% copolymer composition with 0.01% to 70% by cellulosic fibers such that the copolymer anhydride groups react with the cellulosic fiber hydroxyl groups to produce a blowing agent byproduct to form a foamable mixture. The foamed article has a density of not more than 1.3 g/cm3.

  • Patent number: 7541085
    Abstract: A flexible core element having a large bonding surface area suitable for sandwich type construction comprising a plurality of first hexagonal nodes defining a first surface, a plurality of second hexagonal nodes defining a second surface spaced apart from and parallel to the first surface, and a plurality of rectangular wall members which interconnect said first hexagonal nodes to said second hexagonal nodes and define the depth of the core element. Each hexagonal node corresponds to an open hexagonal cell on its obverse surface and serves as a bonding surface. The core element is fabricated from a continuous sheet of material that has been die-cut with a repeating geometrical design, creased and folded, concertina style, in upon itself to make a double-sided core material that is flexible, able to vent, exhibits good bend and shear strength, and has a large surface bonding area rendering it suitable in the construction of lightweight sandwich panels and offering a wide array of other applications.

  • Patent number: 7498072
    Abstract: A long life scent dispersing mat apparatus uses an outer housing with apertures appointed to disperse a scent or fragrance. The fragrance is provided in a fragrant body which is a springy spongy rubber or polymeric sponge soaked with essential oils that have high vapor pressure at ambient temperatures. The fragrant body is inserted into an inner pouch which has small apertures and the stagnant air within the inner pouch attains saturation of fragrance vapor, thereby stopping further evaporation of the essential oils. When the scent-dispersing mat is stepped on, the inner pouch releases the saturated fragrant vapor into the interior of the outer housing and it is released to room air through apertures provided in the outer housing. When force on the mat is released, the fragrant body recovers its original shape and the inner pouch draws fresh make up air and essential oils volatilize until saturation is reached.

  • Publication number: 20090047463
    Abstract: The invention relates to a method of manufacturing a sandwich panel (10). Such a sandwich panel consists of a foamed core layer (12) and at least one thermoplastic cover layer (14). The sandwich panel is made by in situ foaming. In a first assembling step a core web, comprising at least one sheet of a thermoplastic material (12) containing an amount of a suitable physical blowing agent is positioned between two cover layers (14). The assembly of core web and cover layers is arranged between two press plates. Due to heat and pressure applied in a subsequent foaming step, foaming of the core web and effective bonding thereof to the cover layers is achieved. Subsequently the foamed assembly is allowed to cool down. Remaining physical blowing agent is removed during a subsequent drying step at elevated temperature while the outflow of physical blowing agent via the peripheral edges of the panel (10) is restricted, e.g. by taping (24) or clamping by clamps (16, 20).
