DETAILED DESCRIPTION
[0046] 1. Cylindrical form made by rolling one sheet of approximately 8.511-inch [=21.628.0 cm] or A10 paper. To make the shortest size appropriate for children, hold the paper in portrait mode and fold it in half horizontally as shown in FIG. 1A. Then take the folded sheet [which can also be made by folding down newspapers or magazine pages] and roll up the longer edge loosely around two fingers to form a tube approximately 1 inch [=2.5 cm] in diameter as shown in FIG. 1B. In the last step, tuck the free end into the fold made by the other end as shown in FIG. 1C, which will secure the tube as shown in FIG. 1D so it does not unravel. This and the other cylindrical embodiments are all designed to be fit snugly over either the mouth or the nose. They all can be held in place there by hand, by tape, or by sonic strap around the head. To make longer devices appropriate for adults, fold over only one-third to one-fourth of the sheet from the end instead of folding it in half. Then roll it around three fingers instead of two to create a device that is closer to 1.5 inches [=3.8 cm] in diameter and tuck it the same way shown in FIGS. 1B, C and D. For babies, additional folds are needed to reduce the size of the sheet fold before rolling it, and then by rolling it only around one for babies. Preferably single-use-only for hygienic reasons.
[0047] 2. Cylindrical form made with the cardboard tube taken from a toilet paper roll and used as is for adults, or cut shorter for infants and children. Fits better over mouth than nose. For nose use, one side of one end must be pushed in about to inch [=0.6 to 1.3 cm] as shown in FIG. 1E. Single-use-only for hygienic reasons.
[0048] 3. Cylindrical form made with the cardboard tube taken from inside of paper towel roll and cut to approximately 5 to 6 inch [=12.7 to 15.2 cm] length for adults, or shorter for children and much shorter for infants. Fits better over mouth than nose. For nose use, one side of one end must be pushed in about % to inch [=0.6 to 1.3 cm] as shown in FIG. 1E. Single-use-only for hygienic reasons.
[0049] 4. Cylindrical form made from a washable, re-useable, solid tube made of any other material than cardboard with the same approximately 5.51.5-inch [=3.814.0 cm] dimensions and designed to fit snugly over either the mouth or the nose. Designed for multiple uses provided it is washed with soap and dried in-between.
[0050] 5. Rectilinear form made from a paper lunch bag made of absorbent paper, at least 5 inches [=12.7 cm] long for adults, optimally made of Kraft-style paper and optimally size number 4 [=3510.7 inches or 7.612.721.2 cm], that is modified by: [0051] a) cutting or tearing it horizontally to shorten it so the remaining bag is approximately 5 to 7 inches tall [=12.7 to 17.8, cm], and [0052] b) folding over one corner of the rectangular bottom approximately 1 inch [=2.5 cm] and cutting or tearing it off to make a hole approximately 1.5 inch [=3.8 cm] in diameter to allow rebreathing when worn over the nose and mouth. For maximum utility, the edge of the bag ending at the hole should be aligned over the nose. This embodiment can be taped or held snugly to the face but the paper material is not strong enough to support a head strap. Single-use-only for hygienic reasons.
[0053] 6. Triangular form folded in the shape of a mask that covers both nose and mouth. One embodiment of this form can be made from a sheet of paper size 8.511 inches 2228 cm], A-10, or any larger sheet of newspaper folded down to this size. The other embodiment, also described in this section, is made from folding a foil-lined snack-food bag of approximately 610 inches [=15.225.4 cm] in size.
[0054] For the embodiment made from paper, the instructions are as follows: [0055] a) Fold the long side of the sheet about 1.5 inches [=3.8 cm] in from the edge so it creates a collar of double thickness all the way across, as shown in FIG. 2A. [0056] b) Turn the sheet over so this folded collar strip is once again visible along the top edge, as shown in FIG. 2B. [0057] c) With the sheet in landscape orientation, fold the sheet in half vertically, so that the left edge lines up with right and the folded edge is again visible across the top. [0058] d) Fold the lower right corner over until it just touches approximately the middle of the left edge and adjust this fold until it intersects the right edge just below the top band and the bottom edge about 2 inches [=5.1 cm] from the left corner, as shown in FIG. 2C. [0059] e) Fold the right angle of this triangular flap back over to the right so that the longer edge lines up with the hypotenuse and then repeat this fold in the same fashion to form a tight and narrow seam. Crease this edge firmly and then secure it with a piece of tape as shown in FIG. 2D. It can also be secured with paper clips or staples. [0060] f) To use the device, put one hand inside the larger end and spread the device open like a funnel so that it looks similar to the embodiment shown in FIG. 3F. Then open the smaller hole in the distal end. For optimal efficiency, users should lie on their back, grasp the device with their fingertips inside the collar formed by the folded over edge, place it over their nose and mouth, and then hold it snugly against their face by pushing gently on their cheeks with their fingertips as shown in FIG. 4. Like the cylindrical forms, it also can taped to the face or held in place with a head strap that is affixed to the collar on each side of the nose. Single-use-only for hygienic reasons.
[0061] For the embodiment made from a foil-lined snack-food bag approximately 610 inches [=15.225.4 cm], the instructions are: [0062] g) Open both ends of the bag across their entire width without tearing the material as shown on the left side of FIG. 3A. [0063] h) After emptying, cleaning and drying the inside of the bag, turn each end back on itself to form cuffs as shown on the right side of FIG. 3A. The larger cuff is approximately 1 to 1.5 [=2.5 to 3.8 cm] inches wide and the smaller is approximately half the larger. [0064] i) With the bag lying flat as shown in FIG. 3A, fold the lower corner of the smaller cuff towards the opposite long side of the bag to form a flap in the shape of an approximately 30-60-90 degree triangle as shown in FIG. 3B. This fold should stop short of the wider cuff at the left end but should cross entirely through the narrower cuff on the right, leaving approximately 2 inches [=5.1 cm] open along this end. When this fold is correctly aligned, crease it firmly and then tightly roll up the triangular flap from the right angle corner towards the folded edge but not beyond it. [0065] j) Put a piece of tape over the rolled up triangle to keep it from unrolling as shown in FIG. 3C. If no tape is available, the edge can be secured with a few staples or paper clips. [0066] k) Turn the bag over and make a temporary light crease along the dotted line shown in FIG. 3D. Fold the lower corner of the wider cuff up and into the opening at the end of the bag so that it forms two small 45-45-90 degree triangles that are hidden and facing each inside the opening when the bag is smoothed flat, as shown in FIG. 3D). The further that this corner is folded up into the larger cuff, the narrow and smaller the resulting device becomes. [0067] l) Fold the larger end of the bag so that it stands up 90 degrees along the temporary fold shown in FIG. 3D. Open this end of the bag and smooth down the 2 triangles formed at the bottom of the cuff as shown in FIG. 3E. [0068] m) Put one hand inside the larger end and spread the device open like a funnel as shown in FIG. 3F. Then open the smaller hole in the distal end. [0069] n) To use the device with maximum efficiency, the person lies down with their head facing up. They grasp the device with their fingertips inserted all the way into the larger cuff. Then they pull the device over their nose and mouth, and with their fingertips, push the cuff snugly their face as shown in FIG. 4. As with the triangular form made from a sheet of paper, this embodiment also may be taped to the cheeks or held in place with a head strap affixed to the cuff on each side of the nose. Preferably single-use-only for hygienic reasons unless thoroughly washed with soap and dried between uses.
[0070] 7. Conical form made from paper, foam or plastic disposable cup into which a hole is made in the bottom about the size of a bottle cap. The bottom hole can be cut, poked, punched, or torn and does not need to be centered. After making the hole, the larger opening is placed over the nose and mouth and pushed lightly against the face so it forms a snug seal all around, similar to that shown in FIG. 4 for the triangular form. The cup can also be taped against the face or tied around the head. For adults, the appropriate size cup is 8 to 12 ounces [=236.6 to 354.9 ml]; for school children the cup should be approximately half this size, and for infants approximately one quarter the adult size. Preferably single-use-only for hygienic reasons unless thoroughly washed with soap and dried between uses.
[0071] 8. Historical form made from reproductions of masks with extremely long noses that were worn by doctors in the Middle Ages to ward off Plague. These are available in leather, fabrics, plastic, paper, or paper mache. The long nose was originally designed to be stuffed with a mixture of herb and oils thought to prevent Plague, which increased resistance and made breathing through them difficult. Reproductions are sold without any stuffing and can be made into rebreather devices with a single modification.
[0072] The rebreather device of this invention may also be designed for single use, mass manufactured, packaged in multiples, and dispensed from a container.
[0073] The specific embodiments described above are exemplary and not intended to be limiting.
