(9) The EMF/RF radiation shielding means 1 primarily comprises a conductive fabric enclosure 10, a pair of flexible magnets 12a, 12b and a zipper 14. The conductive fabric enclosure 10 is generally a rectangular-shape bag. In an implementation, the conductive fabric enclosure 10 may be configured as a rectangular-shape bag with round corners. It is to be understood that many various sizes, shapes and configurations of the present conductive fabric enclosure are possible relying on demand and purpose. The conductive fabric enclosure 10 is functioned as a Faraday cage and made of metallized polymer material. In an implementation, the conductive fabric enclosure 10 contains a fabric material such as cotton, polyester, nylon, acrylic, or other fabrics combined with one or more of nickel, copper, silver and cobalt, etc. In an implementation of this invention, the conductive fabric enclosure 10 is made of a composition of 60 wt. % polyester, around 25 wt. % metallic copper and around 15 wt. % metallic nickel. The percentages of the composition are approximate and can vary by 5-7 wt. % above or below the mentioned values due to manufacturing abilities. The conductive fabric enclosure 10 may have non-woven fabric material or woven fabric material. The conductive fabric enclosure 10 has a closable and openable top side 101, a left side 102, a right side 103 and a closed bottom side 104. A user can access an article or item like an electrical or electronic device into or out of an interior of the conductive fabric enclosure 10 via the closable and openable top side 101. The conductive fabric enclosure 10 is provided with two accommodations 100a, 100b, for example two enclosed sleeves, at its inner surface under the closable and openable top side 101. The two accommodations 100a, 100b are formed opposite to each other along the closable and openable top side 101. The two accommodations 100a, 100b are extended from a left end of the closable and openable top side 101 connecting the left side 102 to a right end of the closable and openable top side 101 connecting the right side 103. In other words, the length of each of the two accommodations 100a, 100b is equal to or longer than a length L of the closable and openable top side 101. The flexible magnets 12a, 12b are respectively placed inside the accommodations 100a, 100b to hold them in place in order to connect and magnetically seal the Faraday cage. The flexible magnets 12a, 12b may be flexible magnet strips with a length L hidden in the accommodations 100a, 100b along the closable and openable top side 101. The flexible magnets 12a, 12b may have a length fitting with that of the accommodation 100a, 100b to make sure a high level of magnetic sealing of the conductive fabric enclosure 10. In an implementation of the present invention, top portions of the conductive fabric enclosure 10 can be folded and stitched to form two sleeves inside the conductive fabric enclosure 10. The flexible magnets 12a, 12b are respectively slid in the two sleeves. Then, the two sleeves are closed by any known means to become two enclosed sleeves used as the two accommodations 100a, 100b. The flexible magnets 12a, 12b can be flexible rubber magnets, for example, which are made with rubber and NdFeb (Neodymium) magnet powder. The flexible magnets 12a, 12b also can be magnets coated with a thin PVC (Polyvinylchloride) film to protect the flexible magnets 12a, 12b from becoming rusty after prolonged use and exposure to water/humidity. An artisan in the field of this invention will appreciate flexible magnets made with any proper material providing magnetic strength mating with the present conductive fabric enclosure are possible. In an implementation, the left side 102 and the right side 103 of the conductive fabric enclosure 10 are stitched with conductive threads to form stitching sides to create complete shielding of the conductive fabric enclosure 10 from EMF/RF radiation. In an implementation, a stitching density for the left side 102 and the right side 103 is 10-24 stitches/per inch. The zipper 14 is sewn to the conductive fabric enclosure 10 along the closable and openable top side 101 and above the accommodations 100a, 100b that receive the flexible magnets 12a, 12b. The zipper 14 has a length longer than the length L of the closable and openable top side 101. The zipper 14 is used to close the closable and openable top side 14. When the zipper 14 is zipped up to close the conductive fabric enclosure 10 the way as all bags work, the flexible magnets 12a, 12b connect to each other and then magnetically sealing the Faraday cage formed of the conductive fabric enclosure 10. Hence, the circuit of the Faraday cage is closed. The EMF/RF radiation shielding means 1 blocks EMF/RF radiation into and out of the conductive fabric enclosure 10 according to the Faraday cage principle. In an implementation, the zipper 14 may be made of plastic material or metallic material.

(10) When a user places any electric or electronic device emitting or receiving EMF/RF radiation in the EMF/RF radiation shielding means 1, no communication/transmission goes in or out, the EMF/RF radiation shielding means 1 which protects the user from exposure to the EMF/RF radiation or theft of personal information or property. So, the EMF/RF radiation shielding means 1 can provide protection to people's health and protection to digital information and property.

The EMF/RF radiation shielding means 5 comprises a conductive fabric enclosure 50 functioned as a Faraday cage, a pair of flexible magnet strips 52 and a zipper 54. The conductive fabric enclosure 50 is substantially a rectangular-shape receiving body having upper round corners and confined by a top side 501, a left side 502, a right side 503 and a closed bottom side 504. A closable and openable section of the conductive fabric enclosure 50 is defined by the top side 501, the left side 502 and the right side 503. The inner surface of the conductive fabric enclosure 50 beginning from a bottom of the left side 502 passing the top side 501 ended at a bottom of the right side 503 is provided with a pair of accommodations opposite to each other. The pair of the flexible magnet strips 52 are placed and hidden in the accommodations, respectively. The zipper 54 is provided alongside the closable and openable section and outside or above the accommodations for closing the closable and openable section. In an implementation of this invention, the closable and openable section of the conductive fabric enclosure 50 may be defined by the top side 501, a section of the left side 502 and a section of the right side 503. The pair of accommodations is provided at the inner surface of the conductive fabric enclosure 50 along its closable and openable section. Like the conductive fabric enclosure 10 shown in FIG. 1, when the zipper 54 is zipped up to close the conductive fabric enclosure 50 the way as all bags work, the flexible magnet strips 52 connect to each other and then magnetically sealing the Faraday cage formed of the conductive fabric enclosure 50.
