DETAILED DESCRIPTION
(18) Reference will now be made in detail to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.
(19)
(20) Bag portion 11 is made of a flexible plastic sheet material. The flexible plastic sheet material may be a single-layer sheet, or may include multiple layers, or may include multiple layers that are laminated together. Some layers may be porous whereas other layers may be nonporous. In one embodiment, the thickness of the flexible plastic sheet material is less than 10 mils, and may be between 0.10 mils and 1.2 mils in thickness. The flexible plastic sheet material is a nonporous material that may be disinfected with a medical grade disinfectant and may be spray coated with an antimicrobial material. The preferred embodiment of the enclosure is inexpensively manufactured and is disposable. In one embodiment the flexible plastic sheet material includes a polyethylene material. The polyethlyene material has a density and may be of a density between 0.900 to 0.965 grams per cubic centimeter. In another embodiments, the flexible plastic sheet material may include a poly vinyl chloride (PVC) material, a fluorinated hydrocarbon polymer material, a polytetrafluoroethylene (PTFE) material, a silicone rubber material, a nylon material, a flexible silicone composition, a polyamide material, a polyether block amide material, or a polypropylene material, or any other sheet material that is flexible and may be disinfected to reduce or eliminate infectious agents.
(21) The flexible plastic sheet material may be manufactured by a blown-film production process or similar process for creating flexible plastic sheet material. In a blown-film production process, a polythene or similar material is melted and extruded through an annular slit die, usually, vertically to form a thin walled tube. Air is then introduced via a hole in the center of the die to blow the tube causing it to expand and form a bubble. Mounted upon the top of the die, a high speed air ring blows onto the hot film to cool it. The tube of film is then passed through rolls where it is flattened to create the flexible plastic sheet material. This material can then be made into bag portions by sealing the flexible plastic sheet material across the width of the plastic sheet material and then cutting or perforating the plastic sheet material to make each bag portion.
(22) In one example, the size of bag portion 11 is selected to accommodate different devices that may be transported into a medical environment. These devices may include, among other objects, cellular telephones, laptop computers, tablet computers, purses, satchels or briefcases. In one embodiment, the size of bag portion 11 is determined by the amount of flexible plastic sheet portion that bag portion 11 includes and that amount of flexible plastic sheet portion is more than eight square inches and is less than forty square inches. An enclosure with a bag portion including an amount of flexible plastic sheet portion that is more than eight square inches and is less than forty square inches may be used to enclose a cellular telephone.
(23)
(24) In another embodiment, the opening restricting mechanism 14 reduces the opening 12 of enclosure 10 such that all surfaces of cellular telephone 1 are enclosed by bag portion 11 including the surface of touchpad 2. In some embodiments, the flexible plastic sheet portion of bag portion 11 is transparent and allows medical professionals or other users to see and access the control buttons of cellular telephone 1 within enclosure 10. In this manner, a medical professional or other user could control the volume, connect or disconnect calls, or control other functions of the cellular telephone by using the control buttons of cellular telephone 1 while the device is within transparent enclosure 10. In other novel embodiments, the enclosure 10 has an opening or several openings that extend through bag portion 11 to accommodate wires used for power connections, earphone and mouthpiece connections, or other similar type of connecting wires. These openings in bag portion 11 may be specifically located to accommodate connecting wire connections of popular smartphones, tablet or laptop computers, or other electronic devices. For example, a first opening is located in one side of the bag portion to accommodate a cord to a headphones, and a second opening is located in an opposite side of the bag portion to accommodate a cord to a AC-to-DC wall adapter. In other novel embodiments still, the bag portion 11 includes fitted bottoms and/or sides to closely conform to the shape of devices such as smartphones, tablet or laptop computers, or other electronic devices. In these or other embodiments the bag portion 11 may be constructed of an amount of flexible plastic sheet portion that causes the bag portion 11 to enclose a smartphone, tablet or laptop computer, or other electronic device in a snug or tight fitting manner. In one particular embodiment, the bag portion 11 contains an additional pocket structure on an exterior surface of bag portion 11. When the enclosure is provided to the user, this pocket structure includes an alcohol or other type of disinfecting wipe. The alcohol or other disinfecting wipe can also be attached to the bag portion 11 by an adhesive patch, hook and loop fasteners, or in any other similar manner.
(25) In some novel embodiments, the flexible plastic sheet portion of bag portion 11 of enclosure 10 includes an effective amount of an antibacterial material, an antifungal material, or an antiviral material, or mixtures thereof. By including an effective amount of an antibacterial material into the flexible plastic sheet material of bag portion 11 of the enclosure 10, the enclosure 10 may have antibacterial properties sufficient to prevent or reduce the likelihood of infectious agents present on the surfaces of enclosure 10 and also may reduce the likeliness of health-care-associated infections. In one aspect, the antibacterial compound may be gentamycin, clindamycin, or vancomycin or the antibacterial compound may be selected from the group including an aminoglycoside, a lincosamide, a glycopeptide, or mixtures thereof. In other embodiments, other effective antibacterial materials or mixtures thereof are used. In one embodiment, the effective amount of antibacterial material is 0.0001 percent to 5.0 percent by weight of the flexible plastic sheet material. Similarly, if the flexible plastic sheet material of bag portion 11 of enclosure 10 includes an effective amount of an antifungal material in the flexible plastic sheet portion of bag portion 11 of the enclosure 10, the enclosure 10 may have antifungal properties sufficient to prevent or reduce the likelihood of infectious agents present on the surfaces of enclosure 10 and also may reduce the likeliness and occurrence of health-care-associated infections. In one aspect, the antifungal material may be amphotericin B or a compound selected from the group including: a polyene, an azole, an allylamine, a morpholine, a glucan synthesis inhibitor, a systemic agent, an antimetabolite or mixtures thereof. The effective amount of antifungal material may be an amount that is 0.0001 percent to 5.0 percent by weight of the flexible plastic sheet material. In other embodiments, other effective antifungal materials or mixtures thereof are used. If the flexible plastic sheet material of bag portion 11 of enclosure 10 includes an effective amount of an antiviral material in the flexible plastic sheet portion of bag portion 11 of the enclosure 10, the enclosure 10 may have antiviral properties sufficient to prevent or reduce the likelihood of infectious agents present on the surfaces of enclosure 10 and also may reduce the likeliness of health-care-associated infections. In one aspect the antiviral material may be acyclovir or a compound selected from the group including a xanthate compound, gancyclovir, dichloromethane, ethylene vinyl acetate or mixtures thereof. The effective amount of antiviral material may be an amount that is 0.0001 percent to 10.0 percent by weight of the flexible plastic sheet material. In other embodiments, other effective antiviral compounds or mixtures thereof are used. To combine the plastic material of the plastic sheet portion with either an antibiotic material, an antifungal material, or an antiviral material, or mixtures thereof, the precursor plastic material should be mixed with the antibiotic, antifungal, or antiviral materials, and then brought to a molten stage. Other methods of combining similar compounds are well known in the art and can be used to combine or impregnate the plastic sheet material with antibiotic, antifungal, or antiviral materials or mixtures thereof. Where the flexible plastic sheet material is a fibrous and porous material, or where it includes a fibrous and porous constituent layer, the fibrous and porous material may be made to retain an amount of an antimicrobial material. An antimicrobial material can also be provided as part of the flexible plastic sheet material by coating the antimicrobial material onto a plastic sheet layer to form an antimicrobial layer of the overall flexible plastic sheet material.

(33) A user (for example, a health care professional) removes a slip on cover 205 from the dispenser 200, and places the slip on cover over a cellular telephone 206 such that the opening is situated over the touchpad 208 of the cellular telephone 206 as illustrated in the image on the dispenser. The cellular telephone 206 may be placed directly into the slip on cover, or the cellular telephone 206 may already be disposed in another form fitting-cover so that the combination of the cellular telephone and its form-fitting cover is placed into the slip on cover. In one example, the placing of the cellular telephone 206 into the slip on cover 205 involves expanding the opening against a restricting force of the elastic band 207, and then moving the cellular telephone 206 through the expanded opening, and then allowing the elastic band 207 to restrict the size of the opening when the cellular telephone is disposed in the slip on cover.
(34)
(35) In one example, the bottom portion of the flexible plastic sheet material of the slip on cover 205 is of a substantially rectangular shape that is 4.25 to 4.75 inches long and 2.25 to 2.75 inches wide. This rectangular shape substantially matches the size of the bottom surface of the cellular telephone 213. The side portions of the flexible plastic sheet material of the slip on cover 205 are formed so that they substantially match the side surfaces of the cellular telephone 206. Accordingly, when the cellular telephone 206 is in place in the slip on cover 205, the edges of the rim take on the rough form of a rectangle and roughly parallel the edges of the rectangular top surface of the cellular telephone. The rim of the opening of the enclosure (when the enclosure is in place on the cellular telephone) has a substantially rectangular shape as pictured in the image 203 on the dispenser.
(36) After the user has placed the cellular telephone 206 into the slip on cover 205, the cellular telephone 206 (when it is in its slip on cover 205) is carried by the user into an operating room.
(37) Although the enclosure is described above in a specific example as having an opening with an elastic band or drawstring, other examples of the enclosure do not have elastic bands or drawstrings. In one example, the enclosure is a transparent plastic zip lock bag of a seamed construction just like a common commercially-available freezer bag (such as a Ziploc brand double zipper freezer bag available from SC Johnson & Son, Inc. of 1525 Howe Street, Racine, Wis.), except that the novel enclosure: 1) has a size of about 3.25 inches wide by about 6.0 inches long, and 2) has an opening about 2 inches wide by 3 inches long in the top panel of the plastic sheeting of the bag enclosure. The 3.25 inch dimension is the length of the zipper side of the bag enclosure that opens, and through which the cellular telephone can be introduced into the bag enclosure. The opening is positioned so that the opening will be over the touchpad of a cellular telephone when a cellular telephone of a standard size is disposed faceup in the bag enclosure. The opening may be a cutout formed by cutting a 2 inch by 3 inch rectangle out of the top panel of the bag enclosure after the bag enclosure has been otherwise manufactured, or the opening may be formed in a sheet of plastic material when the plastic sheeting is being folded cut and seamed during bag manufacture. A box of such baggie-type enclosures may be packaged in a dispensing cardboard box of the same type used by SC Johnson & Son, Inc. to package its ordinary ziploc brand freezer bags.
(38) The use of these novel enclosures is not confined to operating rooms. In another novel embodiment, the enclosures may be used to transport devices into intensive care units or neonatal care units of hospitals. In yet another novel method, the enclosure is used to transport devices into a clean room of a semiconductor fabrication plant. One alternative method involves the use of enclosures to transport devices into environments of individuals with compromised immune systems. Another novel method involves using enclosures to bring devices into homes or rooms of those inflicted with compulsive disorders to both prevent stress and ease of treatment in those individuals.
(39) Although certain specific embodiments are described above for instructional purposes, the teachings of this patent document have general applicability and are not limited to the specific embodiments described above. Accordingly, various modifications, adaptations, and combinations of various features of the described embodiments can be practiced without departing from the scope of the invention as set forth in the claims.
