  • Patent number: 8535653
    Abstract: An article for sequential dispensing of vapors, notably evaporable fragrances, comprises separated first and second liquids (22, 24). Liquid (22) issues first. Its evaporation may be assisted by a wick (26). The simultaneous evaporation of the second liquid is prevented by an intermediate liquid phase (20). As liquid (22) issues the liquid levels change and there comes a point at which the intermediate phase can no longer prevent the second liquid (24) from flowing past it, to the region from which it can be evaporated. Solids, especially gels, may be employed instead of liquids (22, 24).

  • Patent number: 6426055
    Abstract: Described is a fragrance control release system which is an emulsifier-free, single phase, nonporous, continuous, permeable polymeric film having a substantially uniform thickness of from about 1 up to about 150 microns, having entrapped and dissolved therein molecules of at least one fragrance substance capable of evolving from said film into the environment proximate said film by means of molecular diffusion at a permeation rate of from about 1×10−7 up to about 0.1 mg-mm/cm2-min in a sustained and controlled release manner. Also described is a process for using the aforementioned system for imparting a fragrance into the environment above the unobstructed outer surface of the aforementioned polymer film which is coated on the surface of a solid or semi-solid support, e.g., a solid surface or human epidermis.

  • Patent number: 6299867
    Abstract: An adsorbent is disclosed which is formed either by coating an adsorption mass such as active carbon with a gel-like substance such as the dibasic metallic salt of a macromolecular polycarboxylic acid, soybean curd, jelly, konjak, agar, perilla, gelidium jelly, or chitosanoxalic acid salt gel and subsequently subjecting the coated basis to a freezing treatment or by effecting the coating with the gel-like substance already made to contain a frost damage preventing substance such as glycerin and subsequently depriving the coated basis of the frost damage preventing substance.

  • Patent number: 6235277
    Abstract: Deodorant granulate for lining ashtrays for receiving tobacco ash, including an active component. The active component includes perfume which is one of aromatic and suitable for use on the human body, high viscosity solvent with low evaporation, and undecylenic acid deodorant. The active component is incorporated into non-inflammable mineral granulates whose granularity is selected so as not to leave any trace of dust when used, and has a porosity that enables the mineral granulate to absorb at least 15 wt % of the active component, and to release the active component upon contact with a lit cigarette or cigar. Method for lining ashtrays.

  • Patent number: 6200555
    Abstract: The present invention relates to a deodorant composition capable of removing an odor component such as a carbonyl group-containing compound with high efficiency. The composition includes a deodorizing compound which itself creates no problem of odor and corrosion. The present invention also relates to a deodorizer and filter containing the composition which are compact in size and can remove the odor component in a simple manner, and a method of deodorization using the composition. The deodorant composition includes the compound reactive with the odor component in the presence of moisture, and a water-absorbing substance. The odor component is a carbonyl group-containing compound. The deodorizing compound reactive with the odor component is at least one selected from the group consisting of monohydric phenols, polyhydric phenols, and derivatives thereof, and among them, resorcin is preferable.

  • Patent number: 6177069
    Abstract: A laminated deodorant filter medium is constituted by a plurality of laminate units laminated together; each of which includes a fiber web constituted by a connecting portion and a resin-aggregating portion, both of which are made of a hotmelt resin, and a deodorant particle firmly attached to one surface of the fiber web by way of the resin-aggregating portion. Employable as the deodorant particle is at least two kinds of deodorant particles including an acidic odor deodorant particle, an alkaline odor deodorant particle, and a physically adsorbing particle. As the resin-aggregating portion is formed at a part where a hotmelt nonwoven fabric and the deodorant particle are in contact with each other, the deodorant particle can be firmly attached to the fiber web as a single layer without using a binder, whereby a deodorant filter medium having a low pressure loss and high efficiency can be obtained.
