| CLAIMS 1. Protective sleeve for handles and dispenser therefore, wherein the sleeves are conical and folded bellows-like in the axial direction and are stacked on top of each other in a dispenser so that they can be pulled off. 2. Protective sleeve for handles and dispenser therefor as to claim 1 , wherein the sleeves consist of a multi-ply, compacted cellulose material. 3. Protective sleeve for handles and dispenser therefor as to claim 2, wherein the sleeves have an annular thickening (as in disposable drinking cups) at the conically widened end. 4. Dispensing device for protective sleeves for handles as to claim 1 to 3, wherein the stacked sleeves are arranged in a dispenser in such a way that only the lowest one at a time can be grasped over about 1/4 of its length for removal. 5. Dispensing device for protective sleeve for handles as to claim 1-4, wherein the sleeves are stacked in a cylindrical tube having a constriction or an inhibition bar at its lower end which prevents the sleeves from slipping through by inhibition at their edge thickenings. 6. Dispensing device for protective sleeve for handles as to claim 5, wherein the cylindrical tube is made of a transparent material. 7. Dispensing device for protective sleeves for handles according to one or more of the preceding claims, wherein the protruding ends of the conical sleeves are irradiated with light-emitting diodes. 8. Dispensing device for protective sleeve for handles according to claim 7, wherein the LEDs radiate with a wavelength of 220 to 280 nm. |
Where there are increased requirements for hygeine, e.g. during epidemics, in clinical environments, in public buildings and toilets, in hotels, restaurants, schools and shopping centres, in many cases the contamination of door handles and handles that are touched by many people must be avoided.
TASK OF THE INVENTION/PROBLEM TO BE SOLVED
It is therefore object of the the present invention to provide reliable protection against the transmission of viruses and bacteria, in particular via handles on doors, handrails and toilet brushes.
SOLUTION
The task is solved by paper tubes which are pushed over the handles and then disposed of.
For dispensing, holding tubes are provided which, similar to cup dispensers at vending machines, contain a large number of tubes for contamination-proof dispensing to the user, as well as offering a deposit of the used tubes in containers suitable for disposal. If the paper tubes are accordingly water-soluble, they can also be disposed of via the toilet.
In order to be able to use the sleeves in the above-mentioned stackable form, these must be slightly conical and have a ring at their end, that would pose some resistance at the dispensing point that can be overcome by pulling them off.
To ensure contamination- free dispensing, only the lowest part of the bottom cup should be accessible, which may be coated with antibacterial and anti-viral agents (e.g. lightly sputtered with coloidal silver).
Moreover, the outstanding part of the cones may be illuminated with UV-C LEDs, which have an emphasized spectrum of light at approx. 250 nm wavelength. Since handles have different diameters and shapes, longitudinal bellows-like sleeve shapes made of soft - e.g. kitchen crepe-like material - which is compressed to form a zig-zagged bellow, that ends in the above-mentioned annular ring. A further possibility of issue is to sell theprotective sleeves individually or packed in several as articles to carry along.
DESCRIPTION ALONG TO THE DRAWINGS
Fig. 1 shows a protective sleeve (1) consisting of a longitudinal bellows-like wall (3), lower edge with opening (2) and upper opening with reinforced edge (4).
Fig. 2 shows the dispensing device (5), consisting of the storage tube (6), wall holders (7,
8), the cap (9) with UV-LEDs (10) arranged therein, the holding ring (11), the holding fingers (12), a protective sleeve (1) located in the dispensing device and wall holders (13a, 13b).
Fig. 3 shows how the lowest protective sleeve (1) is held in a dispenser (4) together with other protective sleeves inserted one inside the other. A retaining ring (11) holds the sleeves in such a way that the lowest sleeve (1) in each case can be grasped at the lower part of the wall (3) and pulled downwards against the resistance of the retaining fingers (12) and thus removed individually.
The next sleeve slides down under the force of gravity and is positioned ready to be gripped again. The protruding ends (3) of the sleeves (1) are irradiated by
UV LED(10).
