IPC: B65D81/07
Filed: 1994-01-31
Abstract: PURPOSE:To form a package cushioning body which is inexpensive to produce, light in weight, bearable to great load, high in cushioning performance and easy to dispose after use by fitting a plastic air bag within a tubular body of flexible material. CONSTITUTION:A tubular body 2 is made of flexible material, e.g. the paper of a predetermined thickness, an air bag 3 made of plastic film and filled with air is placed in the tubular body 2 to form a cushioning body 1, which is set at a predetermined place of a packaging case. In this case, a constriction 4 may be formed in at least one intermediate portion of the air bag 3 in the lengthwise direction.

Abstract: Dried fat emulsion products having improved resistance to oxidation at elevated temperatures are produced by the two stage encapsulation of oil or fat globules with a hydrophilic film forming material. An aqueous dispersion of an edible fat or oil, a hydrophilic film forming material, a carbohydrate and water is emulsified to form an oil-in-water emulsion concentrate in which fat globules are encapsulated by the film forming material. After formation of the emulsion concentrate, a second portion of a hydrophilic film forming material is added to the emulsion concentrate in an amount substantially equivalent to the amount of film former in the aqueous dispersion, to provide an additional coating layer of film forming material encapsulating the fat globules. This second portion of film forming material may be added to the emulsion prior to or subsequent to drying of the emulsion concentrate.
