  • Patent number: 4484683
    Abstract: A reclosable carton which is easy to open and reseal is described comprising front and rear panels, connecting side panels with upper portions scored along vertical lines midway between the vertical edges of the side panels, a top flap for closure of the carton having an attached tab, wherein said tab and flap are secured to the side and rear panels by perforations to permit easy removal of the top flap with tab attached. A slot in the rear wall is provided to permit insertion of the tab upon reclosure of the carton which occurs when the top flap is folded along the common edge, created by the inward folding of the side panels along the vertical score lines of the side panel and the carton liner is folded over the top edge of the rear panel to reseal the liner and the carton.

  • Patent number: 4474694
    Abstract: A modified vegetable protein adhesive binder and a process for producing the same is disclosed wherein an alkaline protein dispersion is formed of the protein material and said dispersion is treated with a reducing agent in an amount sufficient to react with the disulfide bonds of the protein material in said dispersion. Initial treatment of the protein material with a reducing agent is followed by reaction of the treated dispersion with a carboxylic acid anhydride such as dicarboxylic acid anhydride, preferably phthalic anhydride in an amount sufficient to modify the protein material such that resultant alkali dispersions of the modified unhydrolyzed protein material have a relatively high viscosity but when used in paper coating compositions containing pigment and other materials such as latex produce relatively low and desirable coating viscosities. Improvements in pick strength, gloss, water holding and ink receptivity of coatings produced with the modified binder of the present invention is achieved.

  • Patent number: 4460613
    Abstract: A process for the production of a dried basal material used for the preparation of a soy based cheese food particularly tofu is set forth wherein a slurry of a soy protein material is formed followed by heating such slurry to a temperature of at least about 220.degree. F. and the retention of such slurry in heated condition under positive pressure for at least a few seconds up to about a few minutes. Following heating of the slurry, the slurry is cooled and mixed with an edible oil which is added to said portein material in an amount sufficient to improve the whiteness of products which are produced with the basal material. The oil is preferably added to said soy material in a proteinaceous solids to oil ratio of between about 5 to 0.2:1. The mixture of oil and soy protein material is dewatered preferably by spray drying and then blended with other ingredients of a basal mix thereby forming a basal material for the production of soy cheese or tofu which has unusual characteristics.

  • Patent number: RE31763
    Abstract: An animal feed supplement in a solid, weather resistant block form and method of making is disclosed. The molasses based feed supplement block, intended for consumption primarily by ruminant animals, although not limited thereto, contains magnesium oxide as a blocking agent. The feed supplement also comprises a water absorbent clay, a phosphorous source and an edible fat or oil in sufficient quantities to set into a solid block in a relatively short period of time at ambient temperatures. A preferred block composition is prepared by a method which comprises admixing the molasses, water, phosphorous source and water absorbing clay under high speed shearing action for an effective amount of time to disperse the clay, admixing edible fat and dispersing it in the mixture and then admixing magnesium oxide to obtain a viscous nutrient mixture that thickens quickly. The mixture is then poured into molds or packages and solidifies to form a hard depackagable block.
