    DETAILED DESCRIPTION OF THE INVENTION

    (15) As used throughout this specification, the word may is used in a permissive sense (i.e., meaning having the potential to), rather than the mandatory sense (i.e., meaning must). Similarly, the words include, including, and includes mean including but not limited to.

    (16) The phrases at least one, one or more, and and/or are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions at least one of A, B and C, one or more of A, B, and C, and A, B, and/or C mean all of the following possible combinations: A alone; or B alone; or C alone; or A and B together; or A and C together; or B and C together; or A, B and C together.

    (17) Also, the disclosures of all patents, published patent applications, and non-patent literature cited within this document are incorporated herein in their entirety by reference.

    (18) Furthermore, the described features, advantages, and characteristics of any particular embodiment disclosed herein, may be combined in any suitable manner with any of the other embodiments disclosed herein.

    (19) Referring to FIG. 1, shown is an illustrative view of prior art. Conventional cotton swabs (indicated at 10) can potentially be counterproductive or even harmful to the person using them for cleaning the ears of another (such as a child). When people use cotton swab tips they frequently clean out some ear wax, but also push some deeper into the medial canal, pushing it up against the tympanic membrane (ear drum) causing impactions that impair hearing or can lead to infection and pain. Trauma to the ear drum also occurs frequently for those users. When applying medicine or makeup or other personal use items, a user can rotate the device so as to have access to four different applicators. Seen in FIG. 1 is a user U cleaning the ear of a child 12 (only the outer portion is seen in this Figure and is indicated at 16), with a conventional swab 10 having oppositely disposed swab tips at 14. This standard use of the prior art will be compared to the utility of the instant invention and will be discussed below.

    (20) Referring to FIG. 2, shown is an illustrative view of a prior art swab in use. When people use cotton swabs, seen here at 10 with the tips indicated at 14, they frequently clean out some of the ear wax but also push some deeper into the medial ear canal 18, pushing it up against the tympanic membrane (ear drum) 20 causing impactions that can impair hearing, lead to infection, and subsequent pain. Trauma to the ear drum is a real possibility with users of the conventional swab 10 as seen here.

    (21) The present invention overcomes these problems by providing a swab tip, with a choice of thickness, having short posts or different lengths for adults (for different uses) that can not penetrate deep into the ear canal and cause damage. This will be explained fully below.

    (22) Referring now to FIG. 3, shown is an illustrative view of the swab 22 of the present invention in use. Swab 22 may have a plurality of short posts or applicator posts 24 having different lengths, with cotton or other material fixedly attached to each distal end. These are best seen in FIGS. 4 through 8 and will be discussed in detail hereinbelow. The applicator posts 24 are transversely disposed in relation to one another and meet, in one embodiment, in a center grip portion 26. The device is multifunctional and lends itself for many uses including cosmetic use and other personal applications.

    (23) Referring to FIG. 4, shown is an illustrative view of the improved swab 22 of the present invention in use. Improved swab 22 includes a plurality of applicator posts indicated at 24. Note that these posts 24 are transversely disposed and radiate from a center portion 26, which in some embodiments of the invention, such as seen here, is made up of a center grip portion 26 that, as can be seen in the Figure, is generally spherical. Other shapes could be used for the purpose, such as cylinders, oblate spheroids, rectangular solids, and the like. Additionally it should be noted that these center portions 26 could be made of various materials, the only common factor being that they should allow the user to easily grip the implement. Also it should be emphasized that the gripping area could be disposed of entirely, simply having the transversely disposed applicator posts 24 cross each other at the center point 26. As aforementioned, the present invention provides a safe productive means for cleaning the exterior of the ear and ear wax buildup without pushing ear wax further and deeper into the ear canal and up against the tympanic membrane, potentially causing damage and loss of hearing. The short post can only enter the ear canal far enough to clean ear wax without damage to the tympanic membrane.

    (24) Referring to FIG. 5, more details of the improved swab 22 are shown. Note the applicator posts 24 are clearly seen in the transversely disposed relationship discussed above. Also it should be noted that applicator posts 24 include a applicator post base 34 proximate the center portion 26 and a distal end 36 proximate the applicator tip 28. It should be also noted here that though the posts 24 are shown at a 90 angle to one another and that the phrase transversely disposed has been used so far in this description, the angles could be altered without departing from the spirit of the invention in such that the disposition of the pairs of applicator posts will prevent the user or caregiver from inserting the applicator post 24 and its attendant applicator tip 28 beyond a certain predetermined distance into the ear canal 18 being cleaned. This angle between two of the posts is shown in FIG. 5 and is indicated at 32, and it is contemplated that an angle in relation to one another (in regard to the center) would be at least 60. This feature of the present invention, though, may be achieved through a number of different angles 32 that need not be detailed here. It should also be emphasized that the length of the applicator posts 24 could vary depending on the use for which the improved swab 22 is contemplated, as opposed to the equal lengths throughout as is seen in the Figures. The posts 24 could be made of wood, paper, a polymer, or some combination of these materials; the manufacture depending again on the contemplated use of the improved swab 22.

    (25) Referring to FIG. 6, shown is a perspective view of the swab 22 of the present invention. In this Figure note the pair of applicator posts indicated at 24A and the pair designated 24B. The reason for this dual designation is that in one contemplated embodiment, these two pairs 24A and 24B could have differing lengths. Also seen in this Figure are the applicator pairs 28A and 28B. The reason for these designated pairs in the Figure is that in certain contemplated embodiments, the size of the applicators (generally designated at 28) could differ one from the other according to the use needed. Returning to the differing lengths of application posts 24, it is known that the distance in an adult from the pinna (outer ear) to the tympanic membrane (eardrum) is approximately 2.5 cm.

    (26) It has been reported that by the pre-teen age, the ear canal typically reaches the adult size. See, Hearing Health & Technology Matters, Wayne's World, Human Ear Canal VIII, Jul. 28, 2014, available at: http://hearinghealthmatters.org/waynesworld/2014/human-ear-canal-viii/.

    (27) More specifically, research in this area has shown that the ear canal length in infants increases from 0.3 cm (3 millimeters) to 1.1 cm (11 millimeters), with increasing age up to 6 months. See, Carolina Abdula and Douglas H. Keefe, Human Auditory Development, Chap. 2, Morphological and Functional Ear Development, pp. 22-24; and Fred H. Bess and Judith S. Gravel, Foundations of Pediatric Audiology, Plural Publishing, Inc., 2006, p. 299.

    (28) It is reported that a majority of the changes in the ear canal length occur between the ages of 6 months and 12 months. See, Fred H. Bess and Judith S. Gravel, Foundations of Pediatric Audiology, Plural Publishing, Inc., 2006, p. 299.

    (29) The ear canal length may reach 1.68 cm (16.8 mm) during infancy (i.e., up to 1 year old). See, Human Auditory Development, p. 20; and Functional Anatomy of the Newborn, Edmund S. Crenlin, 1973, New Haven and London: Yale University Press.

    (30) In general, adult female ear canals tend to be shorter than those of males by about 1 to 3.7 mm. See, Hearing Health & Technology Matters, Wayne's World, Tympanic Membrane-Anatomical Influence on Hearing and Fittings, Apr. 23, 2013, http://hearinghealthmatters.org/waynesworld/2013/tympanic-membrane-anatomical-influence-on-hearing-aid-fittings/.

The Dynamic Ear Canal, Chapter 6, The Human Ear Canal, Ballachanda (Ed), Singular Publishing Group, Inc., San Diego, 1995 pp. 84-111; Bezold, F. Die Corrosions-Anatomie des Ohres, 1882; Chan, J., and Giesler, C., 1980, Estimation of Eardrum Acoustic Pressure and of Ear Canal Length from Remote Points in the Canal, Journal of the Acoustical Society of America, 87(3), 1237-1247; Zemplenyi, J., Gilman, S., and Dirks, D., 1985, Optical Method for Measurement of Ear Canal Length, Journal of the Acoustical Society of America, 78, 2146-2148; Djupesland, G., and Zwislocki, J., 1972, Sound Pressure Distribution in the Outer Ear, Scandinavian Audiology, 4, 197-203; von Bksy, G., 1960, Experiments in Hearing, New York, McGraw-Hill; and Wiener, G., and Ross, D., The Pressure Distribution in the Auditory Canal in a Progressive Sound Field, J. Acoust. Soc. Amer., 1946, 18, 401-408.

    (32) More data regarding ear canal length is available from impressions made on cadavers than data from living patients, which is nonetheless indicative of such lengths for living humans. See, Hearing Health & Technology Matters, Wayne's World, Tympanic Membrane-Anatomical Influence on Hearing and Fittings, Cadaver v. Living Ear Measurements; and Smelt, G., Hawke, M. and Proops, D, 1988, Anatomy of the external ear canal: a new technique for making impressions, The Journal of Otolaryngology, 17, 249-253. Such data shows that the ear canal length for adult males generally falls between 22.6 mm and 27.8 mm, while the ear canal length for the females generally falls between 20.2 mm and 24.8 mm.

    (33) It can be seen then that the instant invention can be made in varying sizes according to the age of the infant or child. Again it should be noted that additionally the transverse posts 24A, 24B could all be of different lengths to allow a single one of the improved swabs 22 to be used in a variety of age-related circumstances.

    (34) Referring to FIG. 7, shown is a perspective view of the present invention with a user U engaging the center grip portion 26. As mentioned above, the center grip portion 26 could be made of a variety of materials and be configured in a variety of shapes. It could be made of a memory material that conforms to the user's grip or be made of a static material, either compressible or non-compressible. Alternatively and, also as mentioned above, it could simply be the intersection point of the two transversely disposed applicator posts 24A and 24B (as seen in FIG. 6). Turning to the actual applicator tips 28 these could be made of a variety of materials, depending on the use for which the improved swab 22 is intended. Cotton, foam rubber (of diverse densities and hardness, or many other pliant and/or absorbent or non-absorbent material could be used. As noted above the applicator tips 28 could be of varying sizes and, along with varying materials, could be combined in the same unit (improved swab 22) to allow for multiple uses: earwax removal, makeup application, or the cleaning of small objects, or working with glue or other solvents to administer or clean crevices, for example.

    (35) Referring to FIG. 8, an embodiment of the present invention indicated at 22A is seen without the center grip portion 26 shown in the above Figures, as it is replaced by the applicator post intersection 30, which serves the same all-around function. The applicator posts 24A and 24B for swab 22A may similarly be made of various materials depending on the use for which the improved swab 22A is to be used. The same applies to the applicator tips 28A and 28B.

    (36) Referring to FIG. 9, shown is an illustrative view of the swab 22 in use for applying makeup. The device provides a safe productive means for applying four different colors of make-up, eye shadow and liner and by using and reusing the four applicators less make-up and swabs will be used, saving money and giving the individual faster and greater control of the cosmetics.

    (37) Referring to FIG. 10, shown is the swab 22 having a plurality of applicator posts with cotton or other material fixedly attached thereto. The device is multifunctional and as shown, can be used to clean the grout 40 between tiles 38 or to apply cleaning agents or solvents to a workpiece. The posts 24 could be made of wood, paper, a polymer, or some combination of these: the manufacture depending again on the contemplated use of the improved swab 22 with the applicator tips 28 of varying sizes and/or varying materials, to allow for multiple uses including cleaning of small objects, or working with glue or other solvents or clean crevices.

    (38) Similar to the aforementioned embodiments, the applicator 100 illustrated within FIG. 11 may have the axis of a first member intersect the axis of a second member at a point 103, at substantially a 90 degree angle, for the first member to form a first swab member 101A and a second swab member 101B, and for the second member to form a third swab member 102A and a fourth swab member 102B. The first member and second members may each be formed to have a circular cross-section, or other any suitable cross-section (e.g., a square shaped cross-section), and the axes may be formed to be coplanar, within ordinary manufacturing tolerances. The first member and second members may each be formed to be rigid, and to not be very flexible, or even flexible at all during normal handling by a person's hand, which rigidity is in part a natural occurrence of the support that is provided by the ninety degree arrangement (i.e., each member/post has an effective length that is shortened by 50% as it is cantilevered from the other member oriented at 90 degrees thereto); however, the first member and second members may each be formed to be rigid enough so as to not deflect more than one-half of a millimeter at the distal end, when a normal handling load (e.g., less than one-half of a pound in one embodiment, and less than one or two pounds in other respective embodiments) is applied to the applicator for insertion into the person's ear canal. The distal ends of the swab members 101A, 101B, 102A, and 102B may respectively have swab materials 101AS, 101BS, 102AS, and 102BS secured thereto, being formed with respective maximum outer diameters 101AD, 101BD, 102AD, and 102BD.

    (39) The respective lengths L1, L2, L3, and L4 for the swab members 101A, 101B, 102A, and 102B may each be the same in one embodiment (i.e., L1=L2=L3=L4). That singular length may be particularly sized so as to leave a small gap G between the swab material at its distal end and the tympanic membrane, when the side of the perpendicular member rests against the pinna of the ear, as shown in FIG. 12.

    (40) In another embodiment, each of the lengths L1, L2, L3, and L4 for the swab members 101A, 101B, 102A, and 102B may be uniquely different (i.e., L1L2; L1L3; L1L4; L2L3; L2L4; and L3L4). For example, as noted above, the length L1 may be sized for an infant, the length L2 may be sized for a toddler, the length L3 may be sized for a child, and the length L4 may be sized for an adult. For example, in one embodiment, L1 may be in the range of 3 mm to 16.8 mm; L2 may be in the range of 16.9 mm to 20 mm; L3 may be in the range of 20 mm to 22 mm; and L4 may be in the range of 22 mm to 28 mm. In another embodiment, the lengths for L1, L2, L3, and L4 may respectively fall in particular ranges, which may be the ranges cited in any example disclosed herein plus a constant added to each, which constant may account for the clocking that the perpendicular member rests against the pinna of the ear, which structure varies around the periphery of the ear (i.e., the pinna is neither symmetric nor regularly shaped). The constant may be a percentage of the ear canal length (i.e., 5% to 15% of the ear canal length, or 15% to 25%, or 25% to 35%). In yet another embodiment, the lengths for L1, L2, L3, and L4 may be unique and particularly sized to only accommodate an infant (i.e., up to one year old); thus L1 may be in the range of 3 mm to 6.5 mm; L2 may be in the range of 6.6 mm to 11.0 mm; L3 may be in the range of 11.1 mm to 13.6 mm; and L4 may be in the range of 13.7 mm to 16.8 mm. For ease of identification by the user, each of the swab members for any embodiment disclosed herein may have markings thereon, and exemplary marking are shown in FIG. 11 (i.e., 0-3 mo. old and 3-6 mo. old and 6-9 mo. old and 9-12 mo. old). As it may be difficult for some users to read the markings, each of the swab members may color coded to indicate increasing length. For example, the post of the shortest length swab member may be a light yellow color, the post of the next longest swab member may be colored a noticeably darker shade of yellow, the shaft of the third longest swab member may be colored an even darker shade of yellow, while the post of the longest length swab member may be the darkest yellow color. The increasingly darker yellow colors/shades may serve to advise increasing caution because of the longer lengths.

    (41) However, the overall size of the ears of an infant tend to be very small as compared to the ear size of an adult, and the infant ear sizes also vary somewhat. See, Yakov Sivan, Paul Merlob, and Salomon H Reisner, Assessment of Ear Length and Low Set Ears in Newborn Infants, Journal of Medical Genetics, 1983, 20, 213-215. Moreover, the ratio of the swab length required to reach and be proximate to the tympanic membrane to the length of the pinna of the ear may be disparate. Therefore, to accommodate the differences in ear size, and to better accommodate proper usage of the applicator by having the perpendicular member properly resting against the side of the pinna of the ear, at least for the infant, for which the length is critical, as an adult may sense when the swab contacts the ear drum, another embodiment of the present invention may have one pair of lengths (e.g., L1 and L3) sized for an infant and one pair of lengths (e.g., L2 and L4) sized for an adult. In one version of this embodiment, the lengths for L1 and L2 may be sized in the range of 3 mm to 6.5 mm to be usable for an infant roughly up to 3 months old, while L3 and L4 may each be in the range of 20 mm to 25 mm to be usable for an adult female. Thus, a caregiving mother of a newborn infant may use the two swab members with lengths L1 and L2 to clean her infant's ears, and may subsequently use the two swab members with lengths L3 and L4 to clean her own ears, and may then dispose of the applicator. Other versions may also be similarly formed and marketed, such as the same version for both infants and the adult female, but where the lengths for L1 and L2 may be sized in the range of 6.6 mm to 11 mm to be usable for an infant roughly between 3 months and 6 months of age; or where the lengths for L1 and L2 may be sized in the range of 11.1 mm to 13.6 mm to be usable for an infant roughly between 6 months and 9 months of age; or where the lengths for L1 and L2 may be sized in the range of 13.7 mm to 16.8 mm to be usable for an infant roughly between 9 months and 12 months of age.
