  • Patent number: 5112688
    Abstract: Microcapsules which are prepared using coacervation processes and/or which have a complex structure in which there is a large central core of encapsulated material, preferably perfume, and the walls contain small wall inclusion particles of either the core material or some other material that can be activated to disrupt the wall are disclosed. The microcapsules that are prepared by coacervation and contain perfume are especially desirable for inclusion in fabric softener compositions that have a pH of about 7 or less and which contain cationic fabric softener. The encapsulated perfume preferably does not contain large amounts of relatively water-soluble ingredients. Such ingredients are added separately to the fabric softener compositions. Ingredients that have high and low volatilities as compared to, e.g., the desired perfume, can either be added to, or removed from, the perfume to achieve the desired volatility.

  • Patent number: 5110004
    Abstract: In the closable lid assembly comprising two elements joined together by means of a hinge, provision is made for the first element or lid to have a channel-shaped peripheral cavity designed to receive the peripheral relief of the second element, in the form of a small frame, which has a flat flange designed to delimit the opening of the packaging onto which the assembly is applied. Either or both the flanks of the peripheral relief have corrugations which cooperate with the vertical walls of the channel provided in the movable lid element, such corrugations forming an airtight seal between the two elements of the assembly. In order to improve further the airtightness of the closure, a gasket is also provided on the bottom of the cavity and comes into abutment against the relief of the small frame.

  • Patent number: 5108006
    Abstract: A tablet dispensing container comprehending a tubular sleeve, a reciprocating element and a locking mechanism. The tubular sleeve forms the container and has two opposing openings therein; a dispensing opening in the lower end and a reciprocating element opening in the upper end. The reciprocating element is attached to the tubular sleeve and is biased toward the upper end. A user manually depresses the reciprocating element which forces the end with the tablet accommodating mechanism through the dispensing opening thereby dispensing a tablet. A locking mechanism prevents the reciprocating element from reciprocating when in a locked position. The locking mechanism permits reciprocation of the reciprocating element when in the unlocked position. The locking mechanism is adapted to remain in either the locked or the unlocked position until manually moved to the other position. Preferably, the locking mechanism includes a visual signal which indicates when the locking mechanism is in the unlocked position.

  • Patent number: 5106635
    Abstract: A method and package for simultaneously microwave heating or baking a plurality of articles such as brownies, cupcakes, muffins or cookies or the like. The method includes the steps of arranging the plurality of articles in a predetermined, vacant-center array within an ovenable container, non-sealingly enclosing the array of articles in the container so that the articles share a common headspace, and applying microwave energy for a sufficient period of time to effect the heating or baking. The method may further include preparing a bakeable batter, subdividing the batter into a plurality of equal portions with one portion in each of a plurality of like receptacles so that, upon being baked, each of the portions becomes one of the articles. A package is also provided to facilitate practicing the method.

  • Patent number: 5104587
    Abstract: Countercurrent liquid/liquid extraction processse for fractionating complex triglyceride mixtures to selectively remove "light" impurities (primarily MMM trglycerides) from MML/MLM triglycerides, or to selectively remove MML/MLM triglycerides from "heavy" impurities (primarily MLL/LML and LLL triglycerides), wherein M is a C.sub.6 -C.sub.10 fatty acid residue or mixture thereof, and wherein L is a C.sub.18 -C.sub.24 fatty acid residue or mixture thereof, are disclosed. In the case of "light" impurities, an oil stream containing MMM and MML/MLM triglycerides is passed countercurrently to a solvent stream containing a polar solvent or a supercritical fluid that is partially miscible with the oil stream to selectively remove the MMM triglycerides. In the case of "heavy" impurities, an oil stream containing MML/MLM, MLL/LML and LLL triglycerides is passed countercurrently to the solvent stream to selectively remove the MML/MLM triglycerides.

  • Patent number: 5104678
    Abstract: An unsaturated or low saturated frying oil which imparts the beefy or tallow flavor to foods that is characteristic of animal fats is disclosed. This oil is made by a process of esterifying glycerine with the unsaturated fraction of animal fat and then deodorizing or refining the resultant triglyceride. The unsaturated fraction of the animal fat contains minor fatty acids which produce this flavor on heating. Usually less than 5 mg of cholesterol/100 gm is in the oil.

  • Patent number: 5102564
    Abstract: An effective amount of perfume/cyclodextrin complex is applied to fabric that is preferably at least partially wetted. A preferred method applies said complex to said fabric in an automatic laundry dryer. The perfume/cyclodextrin complexes are preferably incorporated into solid, dryer-activated, fabric treatment (conditioning) compositions, preferably containing fabric softeners, more preferably cationic and/or nonionic fabric softeners. The complexes provide fabrics with perfume benefits when they are rewetted after drying. Volatile perfume materials including those materials that are commonly associated with "freshness" can be applied to the fabrics in an effective way. Clay provides protection for said perfume/cyclodextrin complexes, especially when certain materials like some nonionic fabric softeners and/or fatty acids are present and in contact with said perfume/cyclodextrin complexes.
