Description

IN THE UNITED STATES PATENT AND TRADEMARK OFFICE

An International Patent Application for:

Ear Hygienic Implements and Kit

Cross-Reference to Related Application

The present application claims the benefit of priority to U.S. Non-Provisional Application Serial No. 16/859,642 filed on April 27, 2020, the contents of which is incorporated by this reference.

Technical Field

The present invention relates to personal hygiene, and more particularly, to brushes, sponges, or any cloth swabs for cleaning the ear internally and externally with or without cleaning reagents.

Background Art

Ears provide an opening into the body which opening is susceptible to infiltration by dirt and pathogens. These may be airborne, transferred by finger, introduced by use of audio objects such as cellular phones and head worn microphones, and introduced inadvertently in the course of washing and showering. In addition, ears are sources of bodily secretions as well, such as wax and sweat.

Currently available implements for ear cleaning, such as cotton fiber tipped swabs, inner ear metal and plastic implements, and rubber and silicone implements entail drawbacks. Swabs may push wax and dirt into the inner ear and trapping bacteria deep within the ear canal. Metal and plastic implements can injure ear tissues. Rubber and silicone implements may be partially ineffective as they cannot engage and transport wax and dirt from the inner ear. Liquid ear cleansing drop products also cannot remove solids, and moreover may be messy to use.

There exists a need for an ear cleaning implement providing additional capabilities.

Disclosure of the Invention

The present invention provides an ear cleaning implement with enhanced ability to trap and extract solid detritus from the ears, compared to many prior art devices. Notably, the implement selectively includes an open cell foam (i.e. sponge), fabric, or bristle lined cleaning head. This construction both enables distribution of cleansing ortherapeutic fluids and also can trap solids for extraction. Both the open cell head and the head bearing bristles may be either permanently fixed to a handle, or removably fixed to the handle. In addition, the cleaning head may include stops or flared sections upon the cleaning head to prevent the cleaning head from being inserted too far into the ear canal, thereby preventing any potential injury.

In addition, a variation of the invention is presented wherein a flexible tube mounted on a stem is utilized for insertion of a cleaning head into the ear canal. The flexible tube houses and compresses a cleaning head in an insertion position and is utilized to provide smooth insertion into the inner ear canal without pushing wax and/or dirt in. Once the flexible tube is inserted, the cleaning head is then advanced out of the flexible tube to an extraction position in the ear canal. In the extraction position, the cleaning head expands to allow for the cleaning of the ear canal as cleaning head is pulled out of the ear canal. Manual (non-electric) and mechanical (electric) versions of this variation are presented.

Each style of cleaning head can engage the handle by elastic contraction or alternatively by interengaging spines or teeth on both the cleaning head and the handle. The portion of the handle engaging the cleaning head may be enlarged in transverse dimension(s).

In an option, the cleaning head may be rotatable and vibrate under electric power.

In a further option, the implement may include two cleaning heads, one at each end of the handle. Where two cleaning heads are provided, the two heads may differ in characteristics such as dimensions, proportions, and specific cleaning surface.

In a further option, the implement may be part of a kit including hygienic or therapeutic/cleansing fluids and pliable finger held or wrapped-on textured pads (or wipes), impregnated pads for applying hygienic fluids previously impregnated into the pads. The kit may include a spray dispenser for some therapeutic fluids. The kit may also include a bottle of cleaning liquid, gel, foam, paste, or oil to be used with this implement with or without water.

In a further option, the implement may include a hollow handle that is utilized to store hygienic or therapeutic/cleansing fluids, which can be accessed by the user through a dispenser such as a pump.

The present invention provides improved elements and arrangements thereof by apparatus for the purposes described which is inexpensive, dependable, and fully effective in accomplishing its intended purposes.

These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.

Modes for Carrying Out the Invention

Referring first to Fig. 1, according to at least one aspect of the invention, there is shown an implement 100 for cleaning ears (not shown). Implement 100 may comprise an elongated stem 102 having a proximal end 104 and a distal end 106, and a flexible cleaning head 108 surrounding and coupled to distal end 106 of elongated stem 102. In the embodiment of Fig. 1, elongated stem 102 serves as a handle, and maybe curved or contoured as shown to enhance grip characteristics. Therefore, elongated stem 102 may have different transverse dimensions 112 at a handle portion 114 thereof.

It should be noted that proximal and distal ends 104, 106 are semantic devices of convenience, and should not be interpreted narrowly as indicating only the very tips of elongated stem 102. Rather, the term “end” should be understood to encompass some of the length of elongated stem 102.

Shown only generically in Fig. 1, cleaning head 108 may comprise an open cell foam, bristle, silicon, rubber, cloth or any fabric (Fig. 2). Alternatively, or optionally in addition to the open cell foam, cleaning head 108 may comprise bristles 110 (Fig. 3) projecting outwardly from a hollow base member 126. Hollow base member 126 is a structural member for engaging enlarged head 116 of elongated stem 102, for receiving therapeutic fluids for subsequent application to the ear, and to support second teeth 122 where the latter are used. In the embodiment of Fig. 2, hollow base member 126 comprises open cell foam. Figs. 2 and 3 illustrate a cavity 124 which maybe formed within cleaning head 108 to accommodate insertion of enlarged head 116 of elongated stem 102. In a further embodiment, the implement may include a hollow stem/handle 102 that is utilized to store hygienic or therapeutic/cleansing fluids, which can be accessed by the user through a dispenser such as a pump.

Unless otherwise indicated, the terms "first", "second", etc., are used herein merely as labels, and are not intended to impose ordinal, positional, or hierarchical requirements on the items to which these terms refer. Moreover, reference to, e.g., a "second" item does not either require or preclude the existence of, e.g., a "first" or lower-numbered item, and/or, e.g., a “third” or higher-numbered item.

Cleaning head 108 may be adhered or configured to removably engage distal end 106 of elongated stem 102. Where cleaning head 108 is configured to removably engage distal end 106 of elongated stem 102 by elastic contraction thereover. This may be a consequence of elastic properties of the open cell foam, the latter being fabricated from a synthetic polymer or from natural sponge material.

In implement 100, elongated stem 102 may have handle portion 114 having transverse dimensions (e.g., as indicated by reference numeral 112), and distal end 106 of elongated stem 102 may comprise an enlarged head 116 having a transverse dimension 118 greater than that of handle portion 114 of elongated stem 102. Of course, handle portion 114 may have transverse dimensions 112 greater in magnitude than transverse dimension 118 of enlarged head 116. In the latter case, elongated stem 102 will have a neck of transverse dimension (e.g., 112 A) smaller than either another transverse dimension 112 of elongated stem 102 and enlarged head 116. Enlarged head 116 improves grasp of elongated stem 102 by cleaning head 108.

In an embodiment shown in Fig. 4, cleaning head 108 is configured to removably engage elongated stem 102 by interengagement of respective first teeth 120 of elongated stem 102 and second teeth 122 of cleaning head 108. Second teeth First and second teeth 120, 122 may be spines or bristles formed integrally with respective elongated stem

102 and cleaning head 108, for example, and may be sufficiently flexible to bend and conform to one another as cleaning head 108 is installed over enlarged head 116.

Bending and conforming will contribute to interengagement of teeth 120 and 122 to a degree enabling retention of cleaning head 108 on enlarged head 116 of elongated stem 102.

In the embodiment of Fig. 4, first teeth 120 project away from elongated stem 102 and second teeth 122 project toward elongated stem 102 when cleaning head 108 is installed on elongated stem 102, as seen in Fig. 1.

In an alternative to removable cleaning head 108 of Figs. 2 and 3, cleaning head 108 may be permanently coupled to distal end 106 of elongated stem 102. This may be accomplished by use of adhesive (not shown), by fusion bonding cleaning head 108 to elongated stem 102, or in any other suitable way.

Turning now to Fig. 5, another embodiment is described wherein implement 100 may further comprise a handle 128 surrounding a proximal end portion 130 of elongated stem 102. Elongated stem 102 is rotatable relative to handle 128. Handle 128 includes a motor 132 rotatably drivingly connected to elongated stem 102, and a battery 134 operably connected to motor 132 to provide power to motor 132. Circuitry 136 (indicated in a single line as segments separated by other electrical components) connects motor 132 to battery 134 and includes an on-off switch 138 controlling operation of motor 132. On- off switch 138 may also control rotational speed of motor 132. Rotation of elongated stem 102 enables cleaning head 108 to expeditiously apply therapeutic fluids to the ear canal (not shown), to extract wax and dirt from the ear canal, or both. Vibratory motion of elongated stem 102 is also contemplated as a means to expeditiously apply therapeutic fluids to the ear canal (not shown), to extract wax and dirt from the ear canal, or both.

Note that cleaning head 108 in Fig. 5 shows that the cleaning head may include a stop 113 that may be formed, molded or added to the cleaning head 108. Stop 113 is a flared portion that prevents the cleaning head 108 from being inserted too deeply into the ear canal by the user an can be added to in any of the embodiments shown herein.

Turning now to Fig. 6, there is shown an embodiment of implement 100 wherein flexible cleaning head 108 is a first flexible cleaning head, and implement 100 further comprises a second cleaning head 140 at proximal end 104 of elongated stem 102. First cleaning head 108 has first surface characteristics and second cleaning head 140 has second surface characteristics different from the first surface characteristics of first flexible cleaning head 108. This enables implement 100 of Fig. 6 to accommodate a wider variety of scrubbing and cleaning techniques than that of Figs. 1 and 5.

In implement 100 of Fig. 6, the first surface characteristics may include a first transverse dimension 142, and the second surface characteristics may include a second transverse dimension 144 different from first transverse dimension 142. Independently of transverse dimensions 142 and 144, the first surface characteristics may include a first length, width and shape 146, and the second surface characteristics may include a second length, width and shape 148 different from first length, width and shape 146. The shapes and contours of first and second cleaning heads 108 and 140 may also differ from each other. Still other characteristics may differ between first and second cleaning heads 108 and 140. For example, first and second cleaning heads 108 and 140 may both comprise open cell foam, but have different pore sizes. In a further example, first and second cleaning heads 108 and 140 may both have bristles 110, but of different lengths, flexibility, and/or thicknesses.

The first surface characteristics may include a first matter retainer (e.g. bristles) and the second surface characteristics may include a second matter retainer (e.g. bristles of different diameter, stiffness, or spacing) different from the first matter retainer. The first matter retainer may comprise open cell foam of one pore size or flexibility, while the second matter retainer may have different pore size or flexibility. A matter retainer is a cleaning head 108 (or 140) having structure for trapping ear wax, dirt, and other solid matter in the ear and retaining the solid matter while withdrawing implement 100 from the ear.

Exemplary dimensions of implement 100 include an overall length (from proximal end 104 to distal end 106) of seven to eight inches. Transverse dimensions of elongated stem may range from three sixteenths of an inch to three quarters of an inch. Wall thickness of cleaning head 108, where comprising open cell foam (Fig. 2), may range from one eighth of an inch to three eighths of an inch, and may vary within this range at different degrees of rotation about the length (i.e., the front view may show different wall thicknesses from a side view). Where used, bristles 110 may vary similarly. Enlarged head 116 may vary in transverse dimensions as well. Exemplary dimensions reflect preferred embodiments, but do not limit dimensional possibilities.

Turning now to Figs. 8 and 9, presented therein is an additional embodiment of an implement for cleaning ears 302. In this variation, flexible tube 304, preferably made of silicon, is mounted on a body that acts as a handle 306. In Fig. 8, it can be seen that the flexible tube 304 houses and compresses a cleaning head 308 in an insertion position and is utilized to provide smooth insertion into the inner ear canal without pushing wax and/or dirt in. Once the flexible tube is inserted into the ear canal, the cleaning head 308 is then advanced out of the flexible tube to an extraction position in the ear canal. In the extraction position shown in Fig. 9, the cleaning head 308 expands to allow for the cleaning of the ear canal as the cleaning head is pulled out of the ear canal. Figs 8 and 9 depict a manual embodiment of the implement for cleaning ears 302. In this embodiment, the operation of the cleaning head in and out of the flexible tube 304, is provided by rod 310 that is fixed to the cleaning head 308 and extends into the handle 306. Movement of the rod 310 is provided by finger slide 312 that is functionally connected to rod 310. Finger slide 312 is retained in a channel (not shown) that includes stops at each travel extreme such that the travel of the rod 310 is confined between the two extremes to avoid potential injury to the user. In addition, flexible tube 304 may include a stop 313 that may be molded in the tube or added to the tube. Stop 313 is a flared portion that prevents the tube 304 from being inserted too deeply into the ear canal by the user.

Turning now to Figs. 10 and 11, presented therein is an additional embodiment of an implement for cleaning ears 402. Again, in this variation a flexible tube 404, preferably made of silicon, is mounted on a stem 405 which detachably connects to a body that acts as a handle 406. In Fig. 10, it can be seen that the flexible tube 404 houses and compresses a cleaning head 408 in an insertion position and is utilized to provide smooth insertion into the inner ear canal without pushing wax and/or dirt in. Shown in Fig. 10 is the detachable component 407 of ear cleaning implement 402 that includes the flexible tube 404, the stem 405, and a compressed cleaning head 408 that is fixed to rod 410. As can be see, rod 410 includes a teethed portion 412.

In the extraction position shown in Fig. 11, the cleaning head 408 expands to allow for the cleaning of the ear canal as the cleaning head is pulled out of the ear canal. Figs 10 and 11 depict an electronic/motorized embodiment of the implement for cleaning ears 402. In this embodiment, the operation of the cleaning head in and out of the flexible tube 404, is provided by rod 410 that is fixed to the cleaning head 408 and extends into the handle 406. Movement of the rod 410 is provided by gear 414 that is rotated by motor 416 that is powered by an energy source 418 (ex. battery). Gear 414 includes a teethed surface 415 that matingly engages with the teethed portion 412 of the rod 410. A toggle switch 420 is electronically connected to the energy source 418 and motor 416 such that the user can control the movement of the cleaning head 408 in and out of the flexible tube 404. Note that the ear cleaning implement 402 may include structural or electronically managed stops (not shown) that includes stops at each travel extreme such that the travel of the rod 410 is confined between the two extremes to avoid potential injury to the user.

In addition, flexible tube 404 may include a stop 413 that may be molded in the tube or added to the tube. Stop 413 is a flared portion that prevents the tube 404 from being inserted too deeply into the ear canal by the user.

Referring primarily to Fig. 7 but also to Figs. 1-6 and Figs 8-11, the invention may be practiced as a kit 200 for cleaning the ears.
