[0009] The embodiments of the present invention will be described below. The embodiments shown below are one aspect of the present invention and do not limit the technical scope of the present invention.
[0010] <Embodiment 1> An oral care kit according to Embodiment 1 will now be described. Figure 1 is an external perspective view showing the mouthpiece 1 included in the oral care kit according to this embodiment, and Figure 2 is a plan view showing the tube 2 filled with the oral composition 3 included in the oral care kit according to this embodiment.
[0011] As shown in Figure 1, the mouthpiece 1 has an upper jaw mouthpiece 10 corresponding to the user's upper jaw and a lower jaw mouthpiece 20 corresponding to the user's lower jaw. The upper jaw mouthpiece 10 covers all the teeth and gums of the wearer's upper jaw, and the lower jaw mouthpiece 20 covers all the teeth and gums of the wearer's lower jaw. In this embodiment of the oral care kit, by providing the upper jaw mouthpiece 10 and the lower jaw mouthpiece 20, it is possible to care for all of the user's upper and lower teeth. However, the mouthpiece 1 may be for the upper jaw only or for the lower jaw only, and the oral care kit may be a care product for either the upper teeth or the lower teeth only. Furthermore, the mouthpiece 1 may be for partial use of either the upper or lower teeth, and the oral care kit may be a care product for partial use of the user's teeth.
[0012] Mouthpieces 10 and 20 are made of hard resin and are pre-molded to cover all teeth and gums in both the upper and lower jaws. Note that mouthpieces 10 and 20 are general-purpose products and are not custom-molded based on individual dental impressions; however, mouthpieces 10 and 20 may be custom-molded based on individual dental impressions.
[0013] As shown in Figure 2, the oral composition 3 is filled into a resin tube 2 and injected into the mouthpieces 10 and 20 before use. The oral composition 3 is a combination of anti-inflammatory components (dipotassium glycyrrhizinate) and bactericidal components (hinokitiol, cetylpyridinium chloride hydrate, isopropylmethylphenol) that kill periodontal disease bacteria. Furthermore, the oral composition 3 is preferably in gel form so that it can quickly reach and remain inside the user's periodontal pockets to enable effective sterilization. In addition, the oral composition 3 dissolves over time in saliva or at body temperature.
[0014] Current oral care is carried out by combining brushing, care using dental floss or interdental brushes, oral cavity rinsing, etc. However, the progression of dental caries caused by bacteria adhering to the tooth surface due to incomplete brushing, the dissolution of the alveolar bone caused by leaving dental calculus in the periodontal pocket, which leads to tooth loss. Also, when infants etc. cannot brush their teeth sufficiently by themselves, parents etc. brush them instead, and oral care for the elderly is often carried out by caregivers. However, if infants or the elderly do not open their mouths or have difficulty opening their mouths, oral care work becomes very laborious and time-consuming.
[0015] The oral care kit according to the present embodiment is, for example, assumed to be worn and used when the user goes to bed. After injecting the oral composition into the mouthpieces 10, 20, the user wears the mouthpieces 10, 20. Thereby, when the user goes to bed, the active ingredient of the oral composition 3 penetrates into the cariogenic bacteria on the tooth surface, the gums, the dental calculus inside the periodontal pocket, etc., to sterilize the miscellaneous bacteria and promote the anti-inflammatory effect. Since the mouthpieces 10, 20 cover all the teeth, sterilization can be performed on all the teeth, so that the occurrence of dental caries caused by incomplete brushing in current toothbrushing can be suppressed. Also, the oral care kit according to the present embodiment can perform oral care by wearing the mouthpieces 10, 20 for a certain period of time at bedtime etc., so that the burden on the user can be reduced compared to current oral care. The oral care kit according to the present embodiment can prevent dental caries and periodontal diseases with an oral care kit that can replace daily toothbrushing. The oral care kit according to the present embodiment can replace current oral care and can prevent dental caries or periodontal diseases. By wearing it, oral care can be performed, so the burden on the user can be reduced compared to current oral care. The oral care kit according to the present embodiment can prevent dental caries and periodontal diseases with an oral care kit that can replace daily toothbrushing. The oral care kit according to the present embodiment can replace current oral care and can prevent dental caries or periodontal diseases.
[0016] Also, the end portions that are in contact with the gums of the mouthpieces 10 and 20 may be thinner compared to other portions. Also, the end portions of the mouthpieces 10 and 20 may have a higher frictional force compared to other portions. Specifically, the end portions of the mouthpieces 10 and 20 may have a higher adhesive force compared to other portions. Thereby, the mouthpieces 10 and 20 can prevent the end portions from adhering to the gums and the oral composition 3 inside from leaking to the outside. Here, the end portions of the mouthpieces 10 and 20 may be the entire portion in contact with the gums, or may be the more end-side portion of the portion in contact with the gums. Also, by the end portions of the mouthpieces 10 and 20 adhering to the gums, it is possible to prevent the mouthpieces 10 and 20 from shifting in position within the oral cavity.
[0017] <Embodiment 2> Next, the oral care kit according to Embodiment 2 will be described. FIG. 3 is a cross-sectional view showing the usage state of the oral care kit according to the present embodiment. The mouthpiece 20 is installed in the lower jaw of the user. In the present embodiment, the mouthpiece 20 for the lower jaw will be described as an example, but the mouthpiece 10 for the upper jaw has the same configuration as the mouthpiece 20.
[0018] Figure 3 shows an excerpt of the mouthpiece 20 covering a lower molar tooth 100. The mouthpiece 20 is positioned to correspond to the user's gums 101 and has return valves 21 and 22 to prevent the oral composition 3 from leaking out. The return valves 21 and 22 extend in the opposite direction from the end of the mouthpiece 20. By having the return valves 21 and 22, the mouthpiece 20 can suppress the leakage of the oral composition 3 to the outside and more effectively sterilize the inside of the periodontal pocket 102. In addition, the return valves 21 and 22 of the mouthpiece 20 may be thinner or less rigid than other parts. This can improve the adhesion of the return valves 21 and 22 to the gums 101. Also, the return valves 21 and 22 of the mouthpiece 20 may have a higher frictional force than other parts, specifically, the outer surface of the return valves 21 and 22 of the mouthpiece 20 may have a higher adhesive force than other parts. This allows the return valves 21 and 22 of the mouthpiece 20 to adhere tightly to the gums, further preventing the oral composition 3 inside from leaking out. In addition, the close contact of the return valves 21 and 22 of the mouthpiece 20 with the gums 101 prevents the mouthpiece 20 from shifting position in the oral cavity. Alternatively, a recess may be provided on the outside of the return valves 21 and 22 for applying adhesive to prevent the adhesive from flowing out, and the return valves 21 and 22 may be bonded to the gums with adhesive, or the outside of the return valves 21 and 22 may be formed of a material with high affinity for adhesive so that the adhesive does not flow out as much as other parts.
[0019] <Embodiment 3> Next, an oral care kit according to Embodiment 3 will be described. Figure 4 is a cross-sectional view showing the oral care kit in use according to this embodiment. The mouthpiece 20 is placed on the user's lower jaw. In this embodiment, the lower jaw mouthpiece 20 is used as an example for explanation, but the upper jaw mouthpiece 10 has the same configuration as the mouthpiece 20.
[0020] Figure 4 shows an excerpt of the mouthpiece 20 covering a lower molar tooth 100. The mouthpiece 20 is positioned to correspond to the user's gums 101 and has return valves 23 and 24 to prevent the oral composition 3 from leaking out. The return valves 23 and 24 extend toward the tooth 100, beyond the end of the mouthpiece 20. The mouthpiece 20, by having return valves 23 and 24, fills the oral composition 3 toward the tooth beyond the return valves 23 and 24, thereby sterilizing the tooth 100 and gums 101 with the oral composition 3. This is possible. Furthermore, it is preferable that the return valves 23 and 24 be positioned so that the oral composition 3 can be immersed in the gums 101 and periodontal pockets 102.
[0021] <Embodiment 4> Next, an oral care kit according to Embodiment 4 will be described. Figure 5 is a plan view showing the mouthpiece 40 provided in the oral care kit according to this embodiment. The mouthpiece 40 is made of soft resin and can be deformed into a shape that covers multiple teeth and gums when the user bites down on it while it is attached to the tip of the user's upper or lower jaw teeth. In the oral care kit according to this embodiment, after the mouthpiece 40 has been deformed, the oral composition 3 is injected into the mouthpiece 40 and attached to the user's upper or lower jaw, thereby providing a mouthpiece that conforms to the shape of the user's teeth and gums.
[0022] <Embodiment 5> Next, an oral care kit according to Embodiment 5 will be described. Figure 6 is a plan view showing the mouthpiece 40 provided in the oral care kit according to this embodiment. The mouthpiece 40 is made of soft resin and can be deformed into a shape that covers multiple teeth and gums by the user biting down on it while it is attached to the tip of the user's upper or lower teeth. In addition, the mouthpiece 40 according to this embodiment has folds 41 and 42 formed at positions corresponding to the front and back of the gums, respectively. When the user bites down on and deforms the mouthpiece 40 of the oral care kit according to this embodiment, the folds 41 and 42 become return valves as shown in Figure 3, preventing the oral composition 3 from leaking out.
[0023] <Embodiment 6> Next, an oral care kit according to Embodiment 6 will be described. Figure 7 is an external perspective view showing the mouthpiece 1 included in the oral care kit according to this embodiment. The mouthpieces 10 and 20 of the oral care kit according to this embodiment have the same configuration as the mouthpieces 10 and 20 of Embodiment 1, but in this embodiment, the oral composition 3 is pre-applied to the inside of the mouthpieces 10 and 20.
[0024] Figure 8 is a cross-sectional view of the mouthpiece 10 when cut along line AA in Figure 7. In this embodiment, the oral composition 3 is formed in multiple layers within the mouthpieces 10 and 20. Specifically, the oral composition 3 is laminated from the mouthpiece 10 side, with a first layer 3A containing a teeth whitening agent and a second layer 3B containing an active ingredient that kills caries or periodontal disease bacteria. After the teeth and gums are sterilized by the second layer 3B, the first layer 3A dissolves, releasing the agent, allowing the first layer 3A to whiten the teeth. In this way, by forming the oral composition 3 in multiple layers and creating layers for each application of the agent, the oral care kit can be used for multiple types of oral care.
[0025] Furthermore, the first layer 3A and the second layer 3B have different components so that when they come into contact with saliva or are warmed to body temperature, the medications dissolve at different times. For example, if the second layer 3B contains a tooth cleaning and sterilizing agent, when the mouthpieces 10 and 20 are first worn, the tooth cleaning and sterilizing agent may dissolve from the second layer 3B to restore tooth function, and the whitening agent may dissolve from the first layer 3A to provide a whitening function. Alternatively, the first layer 3A may contain a fluoride coating agent, so that the fluoride coating agent dissolves after the tooth cleaning and sterilization are complete, and the fluoride coating is applied after the teeth are clean.
[0026] <Variation> Next, an oral care kit according to a modified example of Embodiment 6 will be described. Figure 9 is a cross-sectional view of the mouthpiece 10 when cut along line AA in Figure 7. In this embodiment, the oral assembly Multiple types of component 3 are arranged within the mouthpieces 10 and 20. Specifically, the oral composition 3 has a first layer 3A containing a teeth whitening agent and a tooth cleaning and sterilizing agent in the area corresponding to the teeth in the mouthpiece 10, and a second layer 3B containing an active ingredient that kills periodontal disease bacteria in the area corresponding to the gums in the mouthpiece 10. In this embodiment, the oral care kit contains different agents in the oral composition 3 for each area corresponding to the teeth, gums, and periodontal pockets, and can be fixed in the mouth so that the agent suitable for the teeth, gums, periodontal pockets, etc., is in contact with the desired position. Therefore, the oral care kit can provide effective oral care.
[0027] Furthermore, even when arranging the oral composition 3 as shown in Figure 9, each layer may be formed in multiple layers as shown in Figure 8. This allows the oral care kit to perform multiple types of care on the teeth, such as multiple cleanings and whitening treatments. The oral care kit can also perform different types of care on the gums and periodontal pockets using different medications.
[0028] <Other Embodiments> The mouthpiece in an oral care kit may be disposable or reusable.
[0029] The features included in each embodiment and its modified form disclosed above can be combined in any way. [Explanation of symbols]
