3,001,033 TELEPHQNE STEEHLIZERS Harold Rosenhlum, 35 West St, White Plains, Nfif. Filed Nov. 3, 1953, Ser. No. 771,271 2 Claims. (Cl. 179 185) The present invention relates to improvements in tele phone sterilizers and more particularly to the type which is carried on the perforated cap closing the transmitter end of a hand set instrument.
The principal object of this invention is to provide a novel and improved construction in telephone sterilizers of the character mentioned, in which the components thereof are associated in releasably locked relation affording easy replacement of the chemical cartridge.
Another object there of is to provide a novel and improved telephone sterilizer construction of the type described, which is reasonably cheap to manufacture and maintain and elficient in carrying out the purpose for which it is designed.
Other objects and advantages will become apparent as this disclosure proceeds.
For the practice of this invention, one form it may assume is to have an item which is cup-shaped to be frictionally fitted as a cap for the perforated screw cap of the transmitter. The bottom of said cup is a removable thin container of stuff having sterilizing quality. Such stuff may be granular or in pill form whose active ingredients are volatile and of course, the said container therefor is perforated. Said container is cylindrical and has a peripheral flange of yieldable material which sets in and is engaged by an inward annular channel in the side wall of the bottom hole in said cup member.
In the accompanying drawings forming part of this specification, similar characters of reference indicate corresponding parts in all the views.
FIG. 1 is an elevational view of a telephone instrument shown equipped with a sterilizer embodying the teachings of this invention.
FIG. 2 is a section taken at lines 2-2 of FIG. 1.
FIG. 3 is a section taken at lines 3-3 in FIG. 2 of the sterilizer cartridge.
FIG. 4 is a top plan view of FIG. 3.
FIG. 5 is a top plan view of a sterilizer cartridge of a modified construction.
FIG. 6 is a section taken at lines 6-6 in FIG. 5.
FIG. 7 is a fragmentary enlarged section similar to FIG. 2, but including the cartridge of FIG. 5.
In the drawing, the sterilizer designated generally by the numeral 15, is comprised of a sterilizer component indicated generally by the numeral 16 which is releasably associated with a tubular member denoted generally by the numeral 17. In assembly, these components 16 and 17 form a cup-shaped item which is frictionally fitted as a cap onto the perforated cap 18 of the transmitter end of a hand set telephone instrument 19.
The tubular member 17 has an inner annular groove 20 near its bottom end. The sterilizer component 16, may be comprised of a container holding granules 21 which have been mentioned. This container is made up of cardboard washers 22, 23, 24, 25, with gauze discs 26, 27 held between them in spaced relation as shown. The granules 21 are housed between said gauze discs. All the said washers and discs are of the same diameter to frictionally fit into the lower end of the member 17, but the washer 24 which is between said gauze discs, is of slightly larger diameter to provide a peripheral flange 24', which upon insertion of the sterilizer component 16, flexes and enters the annular groove 20. This locks the parts 16 Patented Sept. 19, 1961 and 17, but allows the forced removal of the sterilizer 16 when its chemical content has become spent and needs to be replaced. Replacement is made with a complete sterilizer component 16, whose manufacturing cost is cheap, because its washer and disc parts are assembled by being merely pasted together by a glue applied to the washers. This is a suggestion for economy of manufacture.
In the modified construction shown in FIGS. 5-7, the container for the chemical stuff 28, may be a box made up of the telescopically fitted pants 29 and 30', whose faces have substantial openings between the narrow spoke-formation ribs 31. Within said box, against said open faces, there are the fine gauze discs 32, between which are housed the granules 28. The outer box part 30 has a peripheral flange 30' intermediate its top and bottom, for releasable engagement in the annular groove 33, and may have another flange 30" at its very top, to rest on the seat 34 within the tubular member 35.
The box parts 29, 30 should be made of a material having some resilient quality, in order to afford proper mounting and removal of the cartridge indicated generally by the numeral 36. Polyethylene is recommended for this purpose and also for the tubular members 17 and 35.
The granules 21 and 28 may for example be paraformaldehyde with a perfume substance, and naphthalene, chlorophyl and other suitable substances.
This invention is capable of numerous forms and various applications without departing from the essential features herein disclosed. It is therefore intended and desired that the embodiments shown herein be deemed illustrative and not restrictive and that the patent shall cover all patentable novelty herein set forth; reference being had to the following claims rather than to the specific description herein to indicate the scope of this invention.
1. In a sterilizer device for the transmitter of a telephone instrument, a tubular member having an annular groove in its inside Wall near an end of said member, a perforated container within said tubular member across said end and in frictional engagement with said member; said container having a perimetral flange of material having some resilient quality; said flange being within and engaged by said annular groove, and yieldable so that it enters said groove when the perforated container is forced into said tubular member and so that it leaves said groove when the perforated container is forced out of said tubular member; said container being comprised of at least two gauze discs in spaced relation, with at least one washer between them and each disc between washers and pasted to them; the washer between said discs, extending beyond the other washers to form the mentioned flange and solid particles having a volatile content of sterilizing quality, housed within said container between the gauze discs; said tubular member being adapted to be set on the cap of the transmitter end of a telephone instrument, so that said container is adjacent said transmitter cap.
2. An article as defined in claim 1, wherein all the washers are of cardboard.
