FR2892025A1 - Anti-microbial handle has covering sleeve of thermo-shrink material with instantly active inorganic or organic anti-microbial agent - Google Patents

Abstract

The handle (1), used e.g. in the home, at work and especially in hospitals, consists of a support (2) with an integral opening/closing mechanism (3), covered by a sleeve (6) of a thermo-shrink material that includes an instantly active inorganic or organic anti-microbial agent. The agent is incorporated in the material of the sleeve during extrusion and is in a concentration that is stronger towards the outer surface. The thickness of the sleeve can be anything from 0.001 - 500 mm; it can have an elongation of 0.001 - 950 per cent, a lengthwise retractability of 0.01 to 99 per cent, and a resistance to traction of 0.01 to 98 per cent.

Description

Human gripping handle with a heat-shrinkable sleeve

antimicrobial

  The present invention relates to principles of design and manufacture of a handle for antimicrobial human grasping and its various fields of application. It is now essential to provide the guarantee of impeccable hygiene in all sectors of professional activity and even in homes. The microbial strains become more and more resistant and are transported very quickly from one place to another. An example of this is the hygiene of hospital staff, clinics and outside visitors who allow microbial proliferation by the hands commonly referred to as manual transmission. This leads to epidemics and considerable infections of people newly operated by nosocomial contamination. 15 A very large vector of contamination is to mention only these without the list being exhaustive: the door handles in general, the stair railings, the wall supports, the trolley or cabinet handles, the shower heads, toilet brush, shower seats, sinkers or toilet seats, 20 shower trolleys .... We will remember that any support can become a nest of microbes more or less important depending on the texture or the material that composes it. In addition, cleaning and disinfecting products often have a limited spectrum of activity on certain types of microbes and fungi and have only a short duration of persistence over time. Added to this are the physical stains which will drastically limit the bactericidal or virucidal or fungal action. There are many patents that deal with disinfectant door handle. I myself developed and developed new disinfectant door handles with new applications described in FR 01 05 77E. This patent is a subsidiary and complementary application of this patent by new applications, manufacturing processes.

  The new antimicrobial grip handle has some very interesting advantages over the handles and the different applications described above. The object of the invention is to provide an antimicrobial grip handle and its improved application derivatives while retaining the advantages of existing products. For this purpose, other features and advantages of the invention will appear on reading the detailed description which follows, a description given with reference to the appended drawings, in which: FIG. 1 represents conventional immediate antimicrobial. An antimicrobial human reference (1) is formed by a support (2) incorporating an opening and closing mechanism and recall (3) a median opening or a median depression (4) allowing the square metal to take a position in said opening and in the passage of the lock of the door and at the same time A connect the two handles together and which will be fixed on the opening of the door. The support also comprises a fixed core or rod (5). According to a variant, the core or stem may be of different section and of varied shape (square, rectangular, oval ...). It seems logical that this same rod can receive excrescences, spurs, striations, perforations .... The new improvement feature is that a thermo-shrinkable antimicrobial sleeve (6) will respectively take place partially or over the entire length of the rod (5) and / or support (2). During the manufacture of the heat-shrinkable sheath, the parent material will include an antimicrobial agent of the inorganic and / or organic type. Thus, during the extrusion of the sleeve and the expansion or the various manufacturing processes, the inorganic and / or organic agent will be present throughout the mass of the heat-shrinkable sleeve. According to another manufacturing preference it may be preferred to provide the concentration of agents schematically a snap action handle or Figure 1: The antimicrobial gripping handle to the outer layer of the sheath or sleeve. Depending on the higher or lower concentrations of one of the inorganic and organic antimicrobial agents, the effectiveness will be increased. For example, a concentration of an antimicrobial agent known under the trademark MICROBAN may be found in large numbers on the outer layer of the retractable sheath and a similar concentration with the antimicrobial agent known under the trademark ALPHASAN. There will thus be a dual action 10 conjugate. Indeed the antimicrobial agent MICROBAN will act immediately against the microbes and the antimicrobial agent ALPHASAN will finish the work and preventing the development of the microbial flora. The ability of the shrink sleeve or sheath to shrink will be a function of the characteristics of the start and the material selected. The retractability may be for example without it being exhaustive 2: 1 or 3: 1 or 4: 1 ... etc. The sleeve or heat-shrinkable antimicrobial sheath may receive impressions on its surface or inside of it. It will also adopt different colors. The sleeve or heat-shrinkable antimicrobial sheath may, depending on the case, receive a design and / or surface structures. The heat-shrinkable antimicrobial sleeve will have the ability to conform to the design of existing products. Indeed, the peculiarity of the present improvement lies in the fact that it can for example be adapted to existing handles and to be fixed by taking the existing conformation thanks to the heat-shrinkable capacities. It is easy to understand the financial savings that will result. In addition, the heat-shrinkable sleeve can adapt to any existing support. But we can also prepare in advance factory new handles receiving the sleeve or heat-shrinkable antimicrobial sheath. The thickness of the sheath or sleeve will be 0.001mm to 500mm. Shore hardness will vary depending on the client's specifications. It will possess the following characteristics elongation of 0.001 to 950%; longitudinal shrinkage from 0.013 to 99.00%; tensile strength of 0.01 kg to 1000 kg / cm 2; lateral elasticity of 0.01 to 99. The antimicrobial heat-shrinkable sheath or sleeve may be made from various raw materials. The plastics or composites known to those skilled in the art and those to come for example we will retain: Polyester, PVC, Polyethylene, Ptfe, polyléfine normal or irradiated; Resins; The sleeve or heat-shrinkable sleeve or the pre-emptive part or all of the parts forming said handle may be constituted and / or formed of rubber, synthetic or natural (a natural rubber, or nitrile rubber, or hydrogenated nitrile rubber , or carboxyl rubber, or polyvinyl nitrile rubber, or chlorprene elastomer, or butyl, or polyethylene, or chlorosulfonated polyethylene, or pvc, or polystyrene, or expanded polystyrene, or polyacrylics, or acrylic elastomer, or fluorinated elastomers, or butadiene-styrene rubber, or polybutadiene, or epychlorohydrin, or modified ethylene-ptopylene-diene (EPDM), or foam rubber, or blends customarily, or foams in general, or a monomeric or polymeric plastic or composite material or a woven or nonwoven fabric, a ferrous and / or non-ferrous metal, an alloy ..., (it will be readily understood that the above-mentioned products can be conjugated together to obtain new complexes) incorporating a biocide or a chemically neutral antimicrobial agent that is stable over time and has an instantaneous action on all the microbes (viruses, bacteria, yeasts, fungi, algae) and having a high potency of remanence without producing or releasing toxicity to a human organism. The heat-shrinkable sleeve or sheath will include or handle partially or wholly at the time of manufacture will include a biocidal or antimicrobial agent composed of disinfectant magnets releasing a magnetic field. The heat-shrinkable sleeve or dwarf may be irifuged, and treated to resist mold and acidic chemicals or bases. The hardness and / or flexibility of the support receiving the sheath may be variable. The covering will also have internal or external adhesion means 05 and temporary or permanent retention of the covering on the mother support. It will obviously be necessary to prepare the mother support on receipt of the recovery. The disinfectant coating will adapt perfectly to the aesthetic conformation of the support. The disinfectant coating will vary in thickness depending on the applications and requirements in which it is placed. The principle principle is a thickness of 0.001 microns to 100cm. The means of adhesion of the covering or sheath to the support will be the adhesive projection, adhesives, glues, heat sealing in all known forms (friction, ultrasound, ...). Another embodiment will allow for example to combine and / or conjugate the present invention of the sleeve or sheath and / or carrier in all these aspects with other biocides existing on the market. These biocides may be to name but a few without this list being exhaustive chemical biocides, biochemical, natural, ferrous or non-ferrous salts, ultraviolet, electronic processes, clear organic biocides and inorganic biocides ... For a better understanding it will be possible to apply a coating for example polyamide known under the name of Rilsan (registered trademark) which is a vegetable paint, ecofitable and nonflammable, isothermal, highly resistant to shocks and UV and / or a zirconium-sodium-silver phosphate ion-exchange-based biocide or the antimicrobial agent Microban (registered trademark) can integrate at the same time the antimicrobial agent constituted by the disinfectant magnets on all carriers of human gripping and in particular the different types of handle for opening or closing a door or a piece of furniture or a valve, a tap .... The invention may be combined with several options. For example, the integration of various polymeric additives for the manufacture of the support or of any part constituting a part of the invention, namely additives to reduce or, on the contrary, to increase the viscosity, to reduce the friction, to increase production rates, slip agents, viscosifiers, nucleating agents, antistatic agents, flame retardants, anti-UV agents, oxygen scavengers, clarifying agents and coloring agents. This is an improved version of the manufacturing method described in my first patent No. 0105776 and 0510591.

  To satisfy another principle of application it can be remembered that after the manufacture of an antimicrobial heat-shrinkable sheath in various forms (sleeve, plate, cube, ball) having patterns, inlays, perforations will be added on one of their part or all on one or both sides a repositionable or permanent adhesive for some cases. This variant will allow the element including the antimicrobial to attach and adapt to all types of media.
