Abstract
Abstract A plastic mold formed of low density polyethylene having a relatively low deformation temperature has an upwardly opening mold cavity preferably with a mold extension extending horizontally from the mold cavity and opening freely horizontally into the cavity. Candy formed of principally sweetening ingredients such as sugar and corn syrup mixtures and the like is heated to approximately 280* F. assuming a hot fluid state, said temperature being in the order of approximately 30* to 100* above the plastic mold deformation temperature. Where the cavity extension is provided, a usual stick is positioned partially in the mold cavity and partially in the cavity extension only part vertically filling the cavity extension and the hot fluid candy is poured into the mold cavity intermediate thereof against a cavity bottom wall spaced from cavity sidewalls. As the hot fluid candy contacts the cavity walls which are at room temperature, a border portion of the candy immediately at least partially solidifies insulating the cavity sidewalls against the remaining hot fluid candy being poured and until all of the candy solidifies thereby preventing deformation of the plastic mold. A similar solidified border is formed by the candy around the stick at the general line between the mold cavity and cavity extension preventing the hot fluid candy from flowing horizontally into the cavity extension despite there being no obstruction between the cavity and cavity extension.

Claim 1
Independent Claim
294 words
In a method of molding high temperature fluid candy in molds formed of low deformation temperature plastic without mold deformation, the steps of: positioning a rigid mold at approximately room temperature and formed of a plastic having a relatively low deformation temperature with a mold cavity thereof accessible for receiving fluid material therein; heating candy to a hot fluid state having a fluid temperature higher than said plastic mold deformation temperature; flowing an initial portion of said heated candy at said higher fluid temperature into said mold cavity; at least partially solidifying to a low heat transfer state a border of said candy initial portion at all mold cavity surfaces contacted during said initial portion flowing by contact of said room temperature mold with said higher fluid temperature candy causing cooling of said solidified candy border contacting said mold cavity surfaces to a temperature below said plastic mold deformation temperature without deformation of said plastic mold; continuing to and completing said flow of said higher fluid temperature heated candy into said mold cavity while continuing said at least partial solidifying to said low heat transfer state said border thereof at all mold cavity surfaces during said continued flowing causing said cooling of said mold cavity surfaces to said temperature below said plastic mold deformation temperature without deformation of said plasTic mold; and during and after said flowing of said higher fluid temperature heated candy into said mold cavity, using said solidified border portions of said candy in said low heat transfer state as a heat insultation barrier during cooling and solidifying of all portions of said candy in said mold cavity inward of said border to protect said plastic mold against heating to said plastic mold deformation temperature and prevent deformation of said mold.
