technical field

The present invention pertains to oral care implements with tissue cleaning elements and medicaments to conform to the tissues of the oral cavity.

Background technique

According to the American Dental Association, the primary cause of bad breath in healthy breath is microbial deposits on the tongue, where the bacterial coating provides an environment for the organic matter and fine particles that cause bad breath. Oral tissues, especially the tongue, are breeding grounds for microbial growth. The papillae nature of the tongue surface creates a unique ecological environment with a very large surface area that facilitates the accumulation of oral bacteria. The anaerobic flora and bacteria on the tongue and other soft tissues in the mouth play a very important role in the development of chronic bad breath, commonly known as halitosis. Generally, bacteria produce volatile sulfur compounds (VSCs). If enough sulfur compounds accumulate, bad breath, or bad breath, can result.

Although tongue scrapers have been used in the past, these are often ineffective, difficult to use, or not suitable for use in institutional settings. Additionally, many of these tongue scrapers are not easily used to clean other tissues in the oral cavity. Despite the benefits gained by cleaning the tissues in the oral cavity, many users avoid using such cleaners due to lack of comfort and/or ease of use.

Furthermore, it is inconvenient or unacceptable for users to clean their tongue and other soft tissues in the oral cavity in public facilities when they are away from home or away from home.

Accordingly, there is a need for an oral care implement having a tongue cleaner that effectively removes tongue bacteria and other debris while maintaining user comfort, that provides an easy-to-use substance that treats oral tissue, and is available in public acceptable and convenient in the facility or while performing the event. There is also a need for an oral appliance that combines the cleaning action of a tissue cleaning element with a medicament.

Detailed ways

Figures 1-5 illustrate an oral care implement 100 having a handle portion or handle 103 and a head 105 for reducing oral malodor and cleaning oral tissues such as the tongue, inner surfaces of the cheeks, lips or gums. Among other features, the oral care implement 100 can be conveniently used away from home or away from home to clean oral tissues. Head 105 includes tissue cleaning element 109 and releasable material 107 . The handle 103 allows the user to easily hold and manipulate the oral care implement 100 . While the handle 103 is substantially cylindrical, it can have many different shapes and configurations. Although the head is preferably of circular or bulbous configuration relative to the handle, in some configurations it may simply be a continuous extension of the handle.

It will be appreciated that, for convenience, the oral care implement 100 is preferably lollipop-like in structure, compact in size, convenient to use, and acceptable. With this structure, the user can easily carry and use the appliance without paying attention to himself or consciously cleaning his mouth, especially in public places. Furthermore, this preferred form of the invention is readily transportable for use by many active users in the course of their activities. This ease and convenience is of obvious benefit to people who wish to clean their mouths prior to interacting, such as work meetings, socializing, etc., especially while on the go, between moves, away from home or public facilities There are obvious benefits for people in the middle of the world.

Referring to Figures 2 and 5, the releasable material 107 may be any suitable biocompatible drug or chemical for oral use. The releasable material 107 is in a suitable shape for oral use in tablet form or any other suitable form. The releasable material 107 can be released inside the mouth, lips or cheeks by several methods, including but not limited to abrasion, temperature change, pH change or dissolution.

The releasable material is preferably a soluble breath freshener, soluble in oral fluids, such as salvia. In particular, the breath freshener may be an antimicrobial substance used to treat anaerobic flora or bacteria located on the tongue or other oral soft tissues. A preferred example of a breath freshener that can be used is triclosan.

In other constructions, the releasable material 107 includes chemicals that have other benefits. For example, chemicals (eg, sensates) may be used to provide a biochemical sensory response to the tissues inside the user's mouth and/or lips. As an example, the chemical capsiason may be used to provide a tingling, warming massage or soothing sensation to the user. In another example, spillanthol may be used to provide residual tingling as well as breath freshening benefits. In another example, chamomile and lavender can be used to provide stress relief and relaxation benefits to the user. In yet another embodiment, a flavor may be used to enhance the user's interest in cleaning the mouth.

In other constructions, the releasable material 107 includes a chemical drug or a drug that benefits the oral cavity. For example, HUMPHRIES 3 or benzocaine can be used for pain relief. In another example, a zo-caine type of drug can be used as an appetite suppressant weight loss treatment. In yet another embodiment, the releasable material may be aspirin or the like. In another alternative configuration, the releasable material may be a health supplement, such as a vitamin or mineral. However, a variety of other chemicals that provide a medicinal or sensory response can be used with the oral care implement. Also, depending on the chemical substance, a large number of chemical substances can be mixed in a tablet or the like of the releasable material, resulting in various benefits.

Tissue cleaning member 109 includes at least one tissue engaging element for cleaning oral tissue and means for retaining releasable material 107 . As configured in FIGS. 1-5 , the tissue cleaning member 109 is preferably formed as a bulbous or disk-shaped member composed of a soft and pliable elastic material for comfortable cleaning and effective removal of bacteria located on oral tissue. Bacteria and debris, such as on the tongue, inner surfaces of the cheeks, gums and lips. Tissue cleaning element 109 also provides effective massaging, stimulation and removal of epithelial cells from oral tissue.

The elastic material of tissue cleaning element 109 can be any biocompatible elastic material suitable for use in oral hygiene devices. In order to provide optimum comfort and cleaning benefits, the elastic material preferably has a hardness in the Shore A hardness range of A8 to A25. For example, a preferred elastomeric material is styrene-ethylene/butylene-styrene block copolymer (SEBS) manufactured by GLS Corporation. However, other manufacturers' SEBS materials or other materials within or outside the above hardness ranges may be used.

The tissue cleaning element 109 is preferably configured with a plurality of tissue engaging elements 111 (FIGS. 1, 3-5), formed in preferred configurations as nubs, which are described below as "slugs" for simplicity. As used herein, "nub" generally means comprising cylindrical protrusions (not limited to the cross-sectional shape of the protrusions) upstanding from the bottom surface. In a general sense, in preferred configurations the height of the nub is greater than the width of the base of the nub (measured in the longest direction). However, nubs may include protrusions that are approximately equal in width and height, or slightly smaller in height than the width of the base. Furthermore, in some cases (eg, where the nub tapers toward a tip or includes a bottom portion that narrows toward a smaller protrusion), the bottom width may be substantially greater than its height.

The nubs 111 are capable of mechanically removing microorganisms and other debris from the tongue and other soft tissue surfaces in the oral cavity. There is now a particular tendency towards the development of a bacterial mulch which provides an environment for the organic matter and microscopic debris that produce bad breath. Microorganisms can be found in the depressions between the papillae on most of the upper surface of the tongue and along other soft tissue surfaces of the mouth. When engaging or rubbing against the tongue surface, the nubs 111 provide soft tissue for a gentle engagement while projecting down into the depressions of the adjacent papillae of the tongue. The resilient construction of tissue cleaning element 109 also enables head 105 to follow the natural contours of oral tissue surfaces, such as a user's tongue, cheeks, lips, and gums. In addition, the nubs 111 are preferably flexible so as to bend to the desired degree to transect and clean the tissue surfaces of the oral cavity. In a preferred construction, the nubs 111 are capable of flexing and bending from their respective vertical axes when lateral pressure is applied in use. This curvature enhances comfort and cleaning of soft tissue surfaces.

In one preferred configuration of tissue cleaning element 109, as shown in Figures 1 and 4-5, nubs 111 are preferably conical or substantially conical in shape, although other configurations are also contemplated. As used herein, "conical" or "conical" is preferably meant to include pure cones, frusto-conical elements, and other shapes that taper toward a narrow end and thereby resemble a cone, whether or not these shapes are uniform, tapered or not. Continuous, with or without circular cross-section. 4, the bottom portion 113 of the conical tissue-engaging element 111 is larger than the corresponding end portion 115 and has a wider cross-sectional area in order to provide effective shear strength to withstand movement of the tissue cleaning element 109 along the soft tissue surface. . The preferred smaller width or diameter of the end 115 combined with the length of the conical nub 111 enables the nub to sweep within the indentations of the tongue or other surface to clean microbial deposits and other debris from the soft tissue surface. This structure further effectively enables oral medications to enter the depressions of the adjacent mastoids of the tongue for antimicrobial treatment.

In a preferred configuration, the thickness or width of the nub bottom is 0.64 millimeters and preferably in the range of about 0.51 millimeters to about 2.00 millimeters. The nub end 115 has a width of 0.127 millimeters and is preferably in the range of about 0.0.10 millimeters to about 0.75 millimeters to optimally pass between the indentations of the mastoids of the user's tongue. The length or height of nub 111 measured from bottom surface 113 to end 115 is preferably 0.91 millimeters and is preferably in the range of about 0.5 millimeters to about 2.5 millimeters, most preferably in the range of 0.75 millimeters to 1.5 millimeters. It should be appreciated that the above dimensions correspond substantially to the typical anatomy of the human tongue without departing significantly from the norm. However, nubs of other sizes and shapes than the given ranges may be used.

As shown in FIG. 3 , nubs 111 are preferably located in concentric rings, rows or rings 117 at spaced radial distances from the center of head 105 . This structure creates natural small circular motions on the surface of the tongue and other soft tissues to effectively clean the tissues and increase the user's saliva flow to release the releasable material 107 into the oral cavity. In addition, the movement of the head and the structure of the nub helps push the releasable material 107 into the adjacent mastoid of the tongue. In a preferred configuration, the nubs 111 on adjacent rings 117 may be arranged radially. For example, adjacent rings 117 have nubs 111 located directly behind each other. A first small piece is referred to herein as being “directly behind” a second small piece when it lies within the range of the lateral boundaries of the second small piece extending in the radial direction. In another alternative arrangement, adjacent rings 117 may be staggered in which the tiles are not directly radially behind other tiles. These structures are able to improve the cleaning of soft tissue surfaces by removing microbes and other debris, and deliver oral medications particularly in the depressions of the tongue adjacent to the papillae. However, the small pieces can be arranged randomly or in patterns in an infinite number of different orders.

While the description of the preferred embodiment of the tissue cleaning element has been discussed, it should be understood that the benefits of the present invention can still be obtained, including a variety of tissue cleaning element configurations. For example, the tissue engaging elements may not be in the form of nubs, such as bumps or hemispheres. Tissue engaging elements may be formed on one side, a portion of one or several sides, both sides, or the entire periphery of the tissue cleaning element. Finally, the tissue cleaning element can be formed from a non-elastic material, or a combination of different materials. In another alternative embodiment, the opposite end 104 of the handle, opposite the head 105, may be used for oral hygiene benefits. For example, tip 104 includes a small toothbrush, a fluff bow, or a toothpick.

In the configuration of the oral care implement 100 shown in FIG. 2, the head 105 preferably includes a bottom 106 with a hole or cavity 108 of a tissue cleaning member 109 (FIG. 1) to accommodate and retain the releasable material in an unreleased form. 107. Disk-shaped bottom 106 provides an overmolding surface for tissue cleaning element 109 . In a preferred construction, releasable material 107 is also covered by the resilient surface of tissue cleaning element 109 (see FIG. 5). Bottom 106 is preferably formed from hard or flexible plastic, but could also be formed from elastomeric or other materials. Additionally, the bottom portion may be a single portion of resilient material forming tissue cleaning element 109 .

As shown in Figures 1 and 3, tissue cleaning element 109 includes holes 110 in the resilient surface to allow releasable material 107 to dissolve and release the chemical in the user's mouth. Alternatively, the releasable material may be a fluid encapsulated in an outer layer that is dissolved or shredded by the user's teeth to release the chemical. In either configuration, effective cleaning of oral tissue surfaces may be achieved through the combined use of tissue cleaning elements 109 that mechanically scrape the tissue surfaces and the benefits of applying a breath freshener/bactericide around the oral cavity. Also, by encapsulating the releasable material within the tissue cleaning element, a substantial portion of the surface area of the tissue cleaning element 109 is devoted to cleaning performance.
