DETAILED DESCRIPTION OF THE INVENTION
[0035] According to the present specification there are provided facial masks for protecting the face from contact with various elements in the environment depending upon where an individual is, For convenience, the discussion herein is presented with respect to the use of the mask in preventing water contact, especially while showering or while washing one's hair, or both. However, it can also be used to protect bandages or exposed wounds and medicaments applied to the face from being soaked or washed away, respectively, or while showering or washing one's hair. Furthermore, its use is not limited to showering or washing hair as it is likewise useable in the event of a sudden cloudburst or downpour, in situations where a worker is creating a lot of dust and want to keep the dust from the face, protecting make-up, medicament, exposed wounds or bandages from contact with clothing as one is putting on and taking off articles of clothing over one's head, etc. Hence, the term “facial mask” as used herein and the appended claims refers generally to the articles disclosed and claimed herein regardless of whether actually used or intended for use in a shower setting, over a sink, in a stream, and regardless of what they are protecting one's make-up, bandages, wounds, medicaments or the like. Additionally, it is to be understood that Applicant's use of the terms periphery and circumference, and variants of each, is a common use and refers to that region of the specified film or film element at and/or near its outer edge. Furthermore, when speaking of an element substantially encircling or being associated with substantially all of the edge or periphery of the film, it is to be appreciated that it is associated with at least 50%, preferably at least 60%, more preferably at least 70% of the periphery or edge of the film. Finally, the phrase “substantially impermeable to water” and similar phrases means that shower water or rain water hitting the outside of the mask will not, under normal circumstances, penetrate through the mask surface in an amount that will adversely affect ones make-up, wash away any medicament, soak any bandage, etc, Indeed, if there is any penetration through the mask surface, it is likely to just drip down the inside surface of the film.
[0036] The facial masks according to the present invention comprise two critical elements: the mask body of the facial mask which defines an interior cavity and the seal and closure means or elements mask which define an opening through which the user inserts their face into the interior cavity. The mask body comprises a single piece of a plastic film or a construction of two or more pieces of aplastic film. The seal and closure means may comprise a single element, such as an elastic band associated with or affixed to the circumferential edge of the mask body or a plurality of elements associated with all or substantially all of the periphery of the mask body for creating a water tight, or nearly so, seal at the interface between the mask edge and the face of the user and for securing the facial mask to the wearer: all as more clearly described below,
[0037] As noted, the mask body comprises a single piece of, a plastic film or a construction of two or more pieces of a plastic film. Most preferably, the mask body may comprise a single piece of water impermeable or substantially water impermeable, low water absorbing polymer film which is both pliable and most preferably transparent or translucent. Alternatively, the mask body may comprise a construction of two or more films, preferably two films, one formed of a rigid or semi-rigid material and the other of a flexible or pliable material. Here, the center region of the mask body is made of the more rigid material and the periphery of the mask is formed of the pliable material: the two materials being bonded to one another by an adhesive, a fusion bond, or the like, with the pliable material completely or substantially encircling the outer edge of the more rigid film: much like a halo would encircle ones head. This feature is shown in
[0038] Suitable polymers from which the films may be formed include natural, synthetic and biodegradable polymers: the latter being especially desirable for disposable facial masks, Exemplary polymeric materials from which the films, pliable and rigid or semi-rigid, may be made include cellulose: polyolefins such as polyethylene, including low density polyethylene (LOPE), linear low density polyethylene (LLDPE), and high density polyethylene (HOPE), polypropylene, including oriented polypropylene (OPP), and ethylene-propylene copolymers; polyvinyl chloride; polyamides; polyvinylidene chloride; polystyrene; polyesters, especially the biodegradable polyesters, especially the aliphatic polyesters like polycaprolactone and copolymers incorporating the same and/or various starches into the polymer chain and/or polymer composition, non-biodegradable polyesters like polyethylene terephthalate; polyimides; and the like, All of which are well known as is the method of making films therefrom.
[0039] The piece of polymer film from which the facial mask is made may be round, elliptical, oblong or any other suitable shape so as to be capable of readily and comfortably encasing the face, and is preferably round or elliptical. The facial masks may be made in any number of sizes, most preferably, the polymer films will be cut to a set number of standard dimensions so that one mask will fit a select grouping of individuals with similarly sized heads and facial regions: much in the way gloves come in multiple standard sizes. The goal is to provide a facial mask which is easily placed upon and removed from the individual and comfortable while being worn.
[0040] As noted above, the mask body is most preferably comprised of a single piece of a pliable polymer film and, thus, is readily able to fit over the individual's face. Pliability arises from both the polymer used and the thickness of the polymer film, Generally speaking, the thickness of the pliable polymer film will be on the order of from about 0.25 to 6 mils, preferably from about 0.35 to 3 mils, most preferably from about 0.4 to 1.5 mils. It will be appreciated that thicker films are also useful and may give more rigidity to the mask body so as to prevent the facial mask from readily collapsing against the face as one shower.
[0041] Though likely too expensive for wide commercial acceptance, as noted above, it is also contemplated that the mask body may be, comprised of a plurality of polymer films, preferably two films one a more pliable film about the periphery of the mask body and the other a stiffer material over the face itself. Both pieces of film may be made of the same polymer, in which case the thickness of the more rigid film is considerably greater than that of the outlying pliable film. Alternatively, and most likely, the two pieces are each made of a different polymer so as to maintain a common, or nearly so, thickness and light weight of the facial mask. In one method of its production, especially if the more rigid material is only semi-rigid, a single film may be formed of the two polymers, e.g., by co-extrusion, The so formed film will have an A:B:A cross section as follows: pliable:semi-rigid: pliable. Even though this film is actually a single film of the two polymers in a side-by-side relationship, for the purpose of this disclosure, the film is deemed a construction of two films.
[0042] Alternatively, and preferably, as shown in
[0043] The second key element of the shower face mask according to the present specification is the seal and closure mechanism. This is the portion of the facial mask responsible for securing the facial mask in place in a water tight or substantially water tight manner. Several options exist for the seal and closure mechanism depending upon the style of facial mask to be made, encasing or veil type, and whether one desires a tie closure or an elastic resistance closure.
[0044] The encasing facial mask is one in which the full face is to be encased within or placed in the interior cavity or volume of the mask. The seal and closure mechanism of the encasing facial mask runs along the forehead (generally along the hairline), down behind the ears, under the jawbone and chin, The seal may be continuous or there may be a small gap in the seal under the chin depending upon the specific closure mechanism employed. In the case of a small gap, as will be discussed below, the closure mechanism, which is integrated into or associated with the periphery of the plastic film, is not so integrated for a small portion of the periphery of the mask, generally less than 10%, preferably less than 5%, more typically on the order of a few inches or so (e.g., 1 to 6, preferably 2 to 3 inches or so) and the closure mechanism has free ends that can be tied to secure the mask in place.
[0045] Typically, with the encasing facial mask two types of closure mechanisms are contemplated. The first is a band, strip, string, or the like having elastic properties, hereinafter the elastic band. The elastic band may be a continuous ring, like a typical rubber band, or a length of an elastormeric material and is most typically made of a rubber, The elastic band, whose circumference, in the case of the continuous ring, or length in its relaxed state is much smaller than the outer circumference of the plastic film. Here, the elastic band is sewn into the outer edge or circumference of the film element using stitching which allows the elastic band to move relative to the plastic film, This allows for a bunching up of the film along the band in its relaxed state; yet, also allows one to increase the circumference of the opening into the volume of the mask body owing to the stretchable nature of the elastic band, the loose stitching and the excess film in the mask body. With the facial mask in place, the individual releases their hold on the elastic band and the tension of the elastic band pulls the circumference of the mask body into a sealing, taut relationship with the individual's skin.
[0046] The second type of closure mechanism is the drawstring type mechanism. In this embodiment, the circumferential edge of the plastic film has associated therewith or sewn therein a seam or pliable tubular element which forms a passage along at least a substantial portion, preferably at least 60%, more, preferably at least 70%, of the edge of the plastic film, the passage having an opening at each end, A drawstring is threaded through the length of the passage and each end of the drawstring extending out of the openings of the passage such that when the mask is worn, the user pulls the drawstrings taut and ties them under the chin so as to secure the mask over one's face.
[0047] The most economical embodiment of the drawstring mechanism is that wherein the outer edge of the film comprising the mask body is folded over onto itself so as to form an area of overlap along the peripheral edge of the film. The overlapped, outer edge of the film is bonded or sewn along the edge so as to create a channel within the overlap region along the outer circumference of the mask body. A small area of overlap is not bonded or sewn so as to create and opening to allow fora drawstring to be inserted into and through the entire length of the channel, emerging out the other end of the channel. In the case of a circular film, the placement of the opening it not an issue; however, in the case of an elliptical or oblong shaped mask body, the opening will be placed in that area which corresponds, in use, to the region that would be under the chin. In this embodiment, the discontinuity in the seam may be nothing more than a cut through the seam which allows the drawstring to effectively enter and exit the seam at the same point on the periphery of the facial mask body or there may a small gap, perhaps an inch or two, which gap closes up, or substantially so, when the drawstring is pulled taut. In the latter instance, a “V” shaped cut out of the mask body may be made at the point of the gap so as to prevent interference of the bunched up film with efforts to tie the drawstring during use.
[0048] Because the entire face is within the volume of the face mask of the encasing type facial mask in use, it is important to ensure proper ventilation for breathing: plastic films otherwise being a known suffocation hazard. Thus, it is important to modify the mask body to enable air flow, especially or preferably in the central region of the film, i.e., that region of the film which, in use, overlays the nose and/or mouth. This may be readily accomplished by introducing a plurality of perforations into the film. The perforations may be formed by any known method including mechanical puncture, high energy perforation, laser perforation, thermal perforation, hot needle perforation, and the like, The perforations will be of minimal dimension/diameter so as to prevent or minimize water penetration into the volume of the face mask. Typical diameters of the perforations will be on the order of a millimeter or so and less: generally providing hole patterns of about 25, more preferably about 50, or more holes per square inch. upwards of 160 or more per square inch. The perforations could also be micro-perforations whose hole patterns are on the order of up to 5000 holes per square inch.
[0049] Alternatively, one may introduce an air permeable element into the mask body. Here a portion of the mask body is removed and replaced with a patch of an air permeable, water impermeable material. Typically, a hole of perhaps about one to two square inches is removed and a large patch of the air permeable material placed to overlay the hole, The patch could be a woven or non-woven fabric, especially one that is naturally or treated to be water repellant. Most preferably, the patch is made of a polymeric material in which air permeability has been imparted to the film. In either case, the patch is sewn, adhered, heat bonded, etc., as appropriate for the chose patch material, to the mask body.
[0050] Other means, e.g., inserts, may be employed to add ventilation to the encasing mask, all as will be readily appreciated by those skilled in the art; however, with current technology, it is most preferred to merely add the perforations directly to the mask body as first discussed above.
[0051] The second type of facial mask is the veil type mask. In this embodiment, the seal between the outer periphery of the facial mask and the user's face does not continue down under the jawbone, and typically ends at or just below the ears. The closure mechanism will, however, continue under the jawbone and chin. In this manner, the lower portion of the mask body hangs free and open so that ample ventilation is allowed into the volume of the facial mask while the closure mechanism still provides the necessary tautness to hold the facial mask in place.
[0052] As noted, both the elastic band and drawstring type closures and seals are employed with the veil type facial mask: the difference here being that the elastic band is only sewn into a portion of the outer circumference of the mask body, the remainder being free to serve as a chin strap. Similarly, the seam through which the drawstring passes in the case of the drawstring closure ends at or below each ear so that the drawstrings themselves are much further exposed, but still tie under the chin. All is will be more clearly shown in the figures, to be discussed below.
[0053] Yet an alternative to the elastic band seal and closure mechanism is one wherein the elastic band ends at the point where it is no longer to be sewn into or affixed to the periphery of the mask body. Here, two rigid “J-shaped” elements are sewn into, affixed to or otherwise attached to each end of the elastic band or the seam containing the same: the “J-shaped” elements intended to hook under each ear. The positioning of the “J-shaped” elements and the length of the elastic band are such that when the “J-shaped” elements are hooked under each ear and released, there is still sufficient tension or elastic memory in the elastic band to secure the facial mask in place and create the water tight or substantially water tight seal along the elastic band. Alternatively, instead of the “J-shaped” elements, drawstrings may be sewn into, affixed to or otherwise attached to each end of the elastic band or the seam containing the same which drawstrings are then used to tie the facial mask in place. Again, in these embodiments, as in all the veil type embodiments, the film of the mask body will continue to a point below the jawbone, preferably to a point an inch or two or more below the chin.
[0054] Having generally discussed the nature of the facial mask and its make-up, attention is now drawn to the figures which more clearly depict the various embodiments of the facial mask and their use.
[0055]
[0056] A structural feature distinguishing the present facial masks from a typical shower cap is the presence of an air permeable region 3 about that portion of the mask body that will overlay the mouth and/or nose. The air permeable region ensures that the wearer will be able to breath in fresh air while showering. Of course, the air permeable region could be located elsewhere on the mask body, for example under the chin, along the jaw bone, or the whole the facial mask could be formed of a water impermeable, air permeable material, However, for cost effectiveness, ease of producing, and comfort/piece of mind for the wearer, its location about the mouth and nose is most desirable.

[0064] Finally,
[0065] As noted above, the facial masks according to the present teachings serve, as their fundamental purpose, as a means to keep various environmental factors, most notably water, from one's face. The most common application is for use in a shower or in other settings where one is washing one's hair, but, as noted above, it can be used as a quick protective device in the case of a sudden storm burst or downpour. Alternatively, it need not be limited to water exposure at all as there are situations where one may want to protect open or exposed wounds, areas of the face that have been treated with a topical medication, etc. from exposure to elements in the air, e.g., dust, pollen, etc. and/or to protect against contact of the same, with clothing while putting on and taking off articles of clothing. In addition to its versatility, another benefit and attribute of the facial masks of the present invention is their low cost and durability allowing for reuse, if desired, as well as a single use item that is used and tossed. The latter is especially attractive to hotels, clubs and the like that offer showers to their patrons. Another benefit, as noted above, is the compactness of the facial mask allowing them to be carried without difficulty in one's purse, backpack, computer case, etc., for use when needed or when the unexpected happens and they are caught in the open during a downpour.
[0066] Although the present invention has been described with respect to specific embodiments and examples, it should be appreciated that other embodiments utilizing the concepts of the present invention are possible without departing from the scope of the invention. Thus present invention is defined by the claimed elements and any and all modifications, variations, or equivalents that fall within thee spirit and scope of the underlying principles set forth herein.
