  • Patent number: 5025504
    Abstract: A liner for helmets, hats, caps or other head coverings has a body with a central section and tapered end sections. The body includes liquid absorbing material and is releasably secured to the head covering for easy replacement. The liners are typically disposable and may be formed with a core of thermoplastic containing other fibers sandwiched between facing and backing sheets. The edges and transversed sections of the body may be densified. Optionally, the liner may be cut in these transverse densified areas to adjust its length.

  • Patent number: 4900377
    Abstract: Articles are formed of materials which have at least one layer comprising a mixture of thermoplastic and other fibers. This latter layer may be thermobonded together and then densified along at least a section of the eventual peripheral edge margin of an article to be formed from the material. Thermoplastic material containing cover sheets may also be secured to the core and densified in this manner. The entire eventual peripheral edge margin of the article is typically densified. The material is cut within the densified region or slightly outside the densified region to provide a soft peripheral edge. Absorbent materials may be thermobonded within the layer and surrounded by a densified edge to fix them within the article. The composite materials are used in manufacturing infant car seat liners and other articles. In addition, sections of the material may be densified and provided with weakened areas, such as perforations, to enable users to selectively separate the articles along the perforations.

  • Patent number: 4892769
    Abstract: Materials have at least one layer comprising a mixture of thermoplastic and other fibers. This latter layer may be thermobonded together and then densified along at least a section of the eventual peripheral edge margin of an article to be formed from the material. Thermoplastic material-containing cover sheets may also be secured to the core and densified in this manner. The entire eventual peripheral edge margin of the article is typically densified. Fire retardant materials may be thermobonded within the layer to fix them within the article. The densified edge also helps to fix these materials in place. The composite materials are used in manufacturing infant car seat liners and other articles. Fire retardant films may be included as cover sheets for these materials. These films are typically bonded at every point of contact to an underlying core.
