  • Patent number: 7628290
    Abstract: For stabilizing a frustoconical beverage container, a stabilizing insulation sleeve comprises a tapered cylindrical sleeve having a plurality of spaced apart vertical slits cut from the smaller open end of such sleeve, forming stabilizing legs. The sleeve is designed to wrap around or nest a similarly shaped, top-heavy, disposable beverage container. The sleeve provides a wide base of support when its legs, formed by the slits, radially expand out to more than 100% of the diameter of the bottom of an inserted beverage cup. This will prevent the inserted cup from easily tipping over on a flat surface, thereby stabilizing it. The ends of the stabilizing legs that spread out on a flat surface can be made of tacky material or of removable adhesive so as to further reduce the problem of sliding across a flat surface.

    Abstract: For stabilizing a frustoconical beverage container, a stabilizing insulation sleeve comprises a tapered cylindrical sleeve having a plurality of spaced apart vertical slits cut from the smaller open end of such sleeve, forming stabilizing legs. The sleeve is designed to wrap around or nest a similarly shaped, top-heavy, disposable beverage container. The sleeve provides a wide base of support for the cup when its legs, formed by the slits, are spread out diagonally on a flat surface. This will prevent the cup from tipping over, thereby stabilizing it. The ends of the stabilizing legs that spread out on a flat surface can be made of tacky material or of removable adhesive so as to further reduce the problem of sliding across a flat surface.

  • Patent number: 5046651
    Abstract: A tubular frame support for a convertible child carrier which makes it possible for a child backpack (FIG. 2) to be converted to a child's seat adapted to a table as a high chair (FIG. 3) and vice-versa. The parallel side members of the tubular frame support are configured like a letter "J": each side member having a first elongated section (15), a parallel second elongated section (11 & 12) which is half the length of the first elongaged section, and a curved connecting section (13) connecting the first and second elongated sections. The first elongated section (15) is bent towards the open end of the second elongated section (11) where the open end of the first elongated section is in line with the second elongated section with a space therebetween where a table can be inserted. The presence of the second elongated section (11 & 12) makes it possible to create a convertible child carrier.
