Definitions

  • FIG! INVENTOR ATTORNI'TY Allll-lPlEl-RMEABLE STERILIZER FILTER This invention relates to air-permeable sterilizer filters.
  • the present invention has for its principal object to provide sterilizer filters for telephone mouthpiece, speaking window and air outlet, which filter can constantly and thoroughly sterilize the air and breath at site of the mouthpiece, speaking window and air outlet for long period, and which is very simple in construction, readily detachable, compact in design and fine in appearance.
  • the present invention is characterized by the fact that a porous sheet member of fine mesh made of antidegeneration material, such as glass fibers of fine mesh or foamed plastic is impregnated with a sterilizer solution, such as benzalkonium I chloride and a liquid perfume as occasion demands, and that both sides of the sheet member is coated with silicone films so that the sheet is prevented from being fluffed and from absorbing moisture and is kept clean for a long time.
  • a sterilizer solution such as benzalkonium I chloride and a liquid perfume as occasion demands
  • FIG. 11 is a plan view of the cap
  • FIG. 2 is a side elevation of the cap
  • FIG. 3 is a sectional view on the line III-Ill of FIG. 1;
  • FIG. 4 is a perspective view ofthe cap
  • FIG. 5 is a perspective view looking from the back side of the cap.
  • FIG. 6 is a perspective view of the cap showing its application upon the mouthpiece of a telephone handset shown in broken lines.
  • a cap formed of soft plastic material is generally indicated at 1.
  • a through hole 2 with a pattern of a rose, in a size large enough to leave only a small peripheral margin therearound.
  • the hole 2 is not always limited in configuration to that ofa flower, but may be patterned after an animal, plant or any geometrical design.
  • the hole 2 should be divided into a suitable number of minor openings by a plurality of retaining ribs or grates 3 formed in one piece with the top wall as shown. These retaining ribs or grates 3 are intended to keep an impregnated sheet, to be described later, from slipping off through the hole 2.
  • the inner wall of the barrel portion 1b of the cap 1 has dimensions and inclinations so chosen that the barrel can adequately fit a telephone mouthpiece 10.
  • annular step 4 of a diameter slightly larger than the circumference of the hole 2 inclusive of its outer contour line.
  • This annular step 4 is provided at its lower end with an annular engaging edge 5 of a narrower width facing downward.
  • annular step 4 In the space defined by the annular step 4 are fitted an impregnated sheet 6 and a retaining plate 7, both of which being somewhat smaller in diameter than the annular step 4.
  • the periphery of the retaining plate 7 is engaged with the upper face of the inwardly facing engaging edge 5 in the annular step 4, in such manner as to press the impregnated sheet 6 against the underside of the top wall la, that is, to the underside of the hole 2.
  • the impregnated sheet 6 is formed of a sheet material of fine mesh such as glass fiber which has no possibility of deterioration, impregnated with a liquid disinfectant such as benzalkonium chloride and a suitable amount of a liquid perfume may be optionally added as desired.
  • a liquid disinfectant such as benzalkonium chloride
  • a suitable amount of a liquid perfume may be optionally added as desired.
  • the perfume is utilized for scenting purposes only and therefore can be eliminated if desired, since it does not serve as a disinfectant.
  • a silicone film is coated on the surfaces of the sheet to prevent fluffing of the fibers and absorption of moisture from the atmosphere. At the same time the silicone film inhibits rapid evaporation of the liquid disinfectant and the perfume (when present). Also, the sheet is kept clean of fingermarks, dirt and dust.
  • silicone film increases the effective life of the filter by more than a factor of four, since it serves as a barrier and thereby slows the evaporation rate of the volatile liquid ingredients. Without the slower evaporation rate produced by the silicone film, the filter would have to be changed quite often and use of the filter would therefore become uneconomical. Since silicone and benzalkonium chloride are not mutually soluble, the silicone film will not dissolve or adversely affect the quality of the latter.
  • the retaining plate 7 is made of a soft plastic material, provided with a throughhole 8 leaving the peripheral margin only, said hole 8 being further divided into a plurality ofopenings by support ribs or grates 9 formed in one piece with the plate.
  • the cap 1 provided with air-permeable sterilizer filter 6 according to the present invention is used as the barrel lb of the cap and is fitted onto the mouthpiece of the telephone handset 10 as shown in FIG. 6.
  • the liquid disinfectant and perfume contained in the impregnated sheet 6 are constantly vaporized at rates very small but enough for sterilizing the mouthpiece and spreading fragrance.
  • the sterilizer filter of the invention precludes any possibility of infection with pathogenic germs through the medium of the telephone mouthpiece as pointed out earlier, and completely eliminates the residual oral odor of the preceding user of the same telephone so that everyone can use the telephone comfortably at all times.
  • the retaining plate 7 is simply engaged with the inwardly facing engaging edge 5 of the annular step 4, it can be readily removed when the disinfectant and perfume in the im pregnated sheet 6 have been exhausted by evaporation, and replaced by a new sheet amply impregnated with fresh sterilizing and fragrant agents.
  • the air-permeable sterilizer filter has been described and illustrated as embodied to a mouthpiece cap for a telephone, however, it is not limited thereto.
  • the filter is capable of being used to sterilize the earpiece of a telephone.
  • the filter is advantageously used for the sterilization of the speaking windows of a station, theater and hospital, and for the sterilization and cleaning of the discharging air from the air outlet of an air-conditioning system, as previously described.
  • An air-permeable sterilizer filter comprising a porous filter fibrous sheet member made of antidegeneration material, said sheet member being impregnated with liquid benzalkonium chloride, both sides of said sheet member being coated with a silicone film which is insoluble with said disinfectant and which prevents said sheet from fiufiing and absorbing moisture, said silicone film being capable of controlling the evaporation of said liquid benzalkonium chloride disinfectant and of keeping said sheet member clean.
