Abstract: This invention relates to a container which is folded from a flat blank of material being provided with a plurality of fold lines forming a bottom wall, side walls and top wall panels in the blank. The side walls are coupled to one another by bellows-type coupling members which are adapted to be inwardly folded during assembly to draw up the adjacent side walls to which there are attached. The top walls are dimensioned such that upon folding into a substantially parallel relationship with the bottom wall will form a closed container which is especially suitable to be used as a gift box or the like. A portion of the bellows-type coupling member may be non-structurally adhered to a side wall of the container acting to greatly enhance subsequent folding and assembling of the container into its finished form. Predetermined fold lines may be pre-folded to allow more convenient assembly, which still enable packaging and handling of the container in a substantially flat form as desired.

Abstract: A self-reinforced polymer composite in the form of a non-laminated shaped article is prepared by (a) melt blending (I) a matrix polymer which is a melt processable flexible chain polymer or first liquid crystal polymer (LCP) and (2) a fiber forming melt processable second LCP under high strain mixing conditions inducing fiber formation, cooling and stretching the resulting blend, and (b) shaping the resulting blend by injection molding or extrusion at a temperature which is above the minimum melt processing temperature of the matrix polymer but below that of the fiber forming second LCP. By shaping at a temperature below the minimum processing temperature of the fiber-forming LCP, the fiber structure formed during cooling is preserved. The resulting shaped articles have outstanding mechanical properties, e./g., tensile strength, modulus and impact strength.

Abstract: A plastic model pattern indicative of the desired completed pattern having prescribed dimensional tolerances and surface finish characteristics is encased within a Type I material which may be a soluble wax or low melting point material, and subsequently leached from the Type I material to define a cavity corresponding to the dimensional characteristics of the plastic model pattern. A Type II material, such as an insoluble wax or high melting point material, may then be injected into the cavity to recreate the plastic model pattern without the use of any plastics materials, to avoid potentially mold deteriorating expansion of such plastics materials. The mold form of Type I material may then be removed by leaching, melting or the like to reveal the completed expendable pattern usable in a lost wax mold forming process. An injection apparatus and die structure is advantageously utilized in conjunction with the process to achieve high production quality and insure proper formation of the expendable pattern.
