Description
Technical Field
The present invention relates to an oral cavity massager, a head member for an oral cavity massager, and an oral cavity massaging method using the oral cavity massager.
Background
In recent years, oral cavity massage by a dental hygienist or the like has been performed for the purpose of beauty, relaxation, prevention of diseases, or the like. For example, by massaging the hard expression muscles from the oral cavity, effects such as lightening the grain of statute and lifting the corner of the mouth can be obtained. In addition, for example, the oral cavity is stimulated by massage to promote salivary secretion, thereby suppressing proliferation of bacteria in the oral cavity and preventing dental caries, periodontal disease, and the like.
In the case of performing such oral massage by oneself, the user can perform the massage by putting his or her finger into the oral cavity, but in an inexperienced state, the oral cavity may be damaged by the nail or the like. Further, it is not preferable from the viewpoint of hygiene.
In order to solve such a problem, for example, patent document 1 discloses a technique of massaging the oral cavity using a specific massage tool. Specifically, patent document 1 discloses a statute line massager including: a massage part inserted into the oral vestibule and pressed against the oral mucosa above the upper lip corresponding to the generation part of the ordinance print; and a bar-shaped holding section having a grip section held by a palm and a finger-engaging section pinched by two fingers.

Detailed Description
The embodiments of the present invention will be described below with reference to the drawings and the like, but the present invention is not limited to the embodiments described below as long as the gist of the present invention is not violated. Note that, in the drawings, the same reference numerals are used for the same portions, and the like, and different reference numerals may be used.
[ first embodiment ]
First, an intraoral massager according to a first embodiment of the present invention will be described with reference to fig. 1 and 2. Fig. 1 (a) is an example of a front view of the oral cavity massager, and fig. 1 (b) is an example of a rear view of the oral cavity massager. Fig. 2 is an example of a side view of the oral cavity massager, and is a view of the oral cavity massager viewed from the direction of arrow a shown in fig. 1 (a).
The oral cavity massager 1 shown in fig. 1 and 2 includes at least a head 11 and a handle 21. The user inserts the head 11 into the oral cavity while holding the handle 21, and pushes the pressing surface 13 formed on the head 11 against a predetermined portion in the oral cavity, thereby massaging the oral cavity.
The head 11 has a substantially elliptical recess 12 formed along the outer periphery of the head 11 in a plan view. The head 11 has a pressing surface 13 (hatched portion in fig. 1 (b)) for pressing and massaging the inside of the oral cavity on the surface opposite to the surface having the depression 12.
The pressing surface 13 is, for example, a region located on the opposite side of the shank 21 when the head 11 is divided into two regions by a line segment n passing through the end on the shank 21 side on the major axis La and orthogonal to the major axis La. The region on the shank 21 side is a connection portion. The definition of the long axis La will be described later.
The pressing surface 13 has a shape imitating a finger pad of a human thumb at least in a part thereof. With such a configuration, for example, the same massage as the oral cavity massage by a dental care professional can be performed, and the massage effect can be improved. From the viewpoint of further improving the massage effect, the entire pressing surface 13 is preferably shaped to follow the pad of a human thumb.
Here, the shape imitating the finger pad of the thumb refers to a shape in which the pressing surface 13 has a substantially convex curved structure when the head 11 is viewed from the direction of the arrow a shown in fig. 1 (a), and the pressing surface 13 has a substantially convex curved structure when the head 11 is viewed from the direction of the arrow B shown in fig. 1 (a), for example.
The ratio of the lengths of the major axis La and the minor axis Sa (major axis length/minor axis length) on the pressing surface 13 is 17/10 or more, preferably 26/15 or more, and more preferably 53/30 or more. The ratio of the length of the major axis La to the minor axis Sa on the pressing surface 13 is 3/1 or less, preferably 13/5 or less, and more preferably 11/5 or less. When the ratio of the lengths of the long axis La and the short axis Sa is less than 17/10 and when the ratio of the lengths of the long axis La and the short axis Sa exceeds 3/1, it is difficult to appropriately stimulate the region to be massaged in the oral cavity, and the massage effect is reduced.
Here, the minor axis Sa is, for example, a line segment having the longest length among line segments extending through the head 11 so as to be orthogonal to the longitudinal direction of the oral massager 1 in a plan view. The major axis La is, for example, a line segment that passes through the midpoint M of the minor axis Sa and is orthogonal to the minor axis Sa, and is also a line segment having the midpoint M as its midpoint. That is, on the long axis La, the length of a line segment from the midpoint M toward the tip of the head 11 is equal to the length of a line segment from the midpoint M toward the stem 21.
The length of the major axis La is, for example, preferably 20mm or more, more preferably 30mm or more, and further preferably 40mm or more. The length of the major axis La is, for example, preferably 70mm or less, more preferably 60mm or less, and still more preferably 50mm or less. When the length of the major axis La is less than 20mm, the massage efficiency tends to be lowered because the area of the pressing surface 13 is relatively reduced. In addition, when the length of the long axis La exceeds 70mm, the area of the pressing surface 13 is relatively increased, and thus it may be difficult to appropriately stimulate the region to be massaged, and the massage effect tends to be reduced.
The length of the short axis Sa is, for example, preferably 10mm or more, more preferably 15mm or more, and still more preferably 20mm or more. The length of the short axis Sa is, for example, preferably 40mm or less, more preferably 35mm or less, and still more preferably 30mm or less. When the length of the short axis Sa is less than 10mm, the massage efficiency tends to be lowered because the area of the pressing surface 13 is relatively reduced. In addition, when the length of the short axis Sa exceeds 40mm, the area of the pressing surface 13 is relatively increased, and thus it may be difficult to appropriately stimulate the region to be massaged, and the massage effect tends to be reduced.
The length L1 in the longitudinal direction of the head 11 is, for example, preferably 40mm or more, more preferably 50mm or more, and still more preferably 60mm or more. The length of the major axis La is, for example, preferably 90mm or less, more preferably 80mm or less, and still more preferably 70mm or less.
Thickness T as head 111For example, it is preferably 5mm or more, more preferably 7mm or more, and still more preferably 9mm or more. The thickness T of the head 111For example, it is preferably 20mm or less, more preferably 15mm or less, and still more preferably 11mm or less. At a thickness T1If the thickness is less than 5mm, the mechanical strength may be reduced, and the durability may be reduced. In addition, in the thickness T1When the diameter exceeds 20mm, it tends to be difficult to perform massage in the oral cavity.
As a length T in the thickness direction between the uppermost position and the lowermost position of the head 11 in FIG. 22For example, it is preferably 10mm or more, more preferably 12mm or more, and still more preferably 14mm or more. Further, the length T is2For example, it is preferably 25mm or less, more preferably 20mm or less, and still more preferably 16mm or less. In lengthT2Less than 10mm, and a length T2When the thickness exceeds 25mm, it tends to be difficult to form the pressing surface 13 into a shape suitable for massage, and as a result, the massage effect may be reduced.
As a length T in the thickness direction between the lowermost position of the head 11 and the lowermost position in the end portion of the head 11 on the shank 21 side in FIG. 23For example, it is preferably 1mm or more, more preferably 2mm or more, and further preferably 3mm or more. Further, the length T is3For example, it is preferably 6mm or less, more preferably 5mm or less, and still more preferably 4mm or less. At a length T3If the diameter is less than 1mm, the handle 21 strongly contacts the lips during massage, which may cause pain. In addition, in the length T3If the thickness exceeds 6mm, the portion of the pressing surface 13 that contacts the oral cavity is reduced, and the massage effect may be reduced.
As T1And T2Ratio of (T)1/T2) For example, it is preferably 5/25 or more, more preferably 5/14 or more, and still more preferably 5/10 or more. In addition, as T1And T2The ratio of these components is, for example, preferably 15/16 or less, more preferably 9/10 or less, and still more preferably 8/10 or less. By making T1And T2The ratio of the first to the second ratio is within the above range, and the shape can be more suitable for massage.
As T3And T2Ratio of (T)3/T2) For example, it is preferably 1/25 or more, more preferably 1/14 or more, and still more preferably 1/10 or more. In addition, as T3And T2The ratio of these components is, for example, preferably 6/10 or less, more preferably 4/10 or less, and still more preferably 5/20 or less. At T3And T2When the ratio is less than 1/25, the handle 21 strongly contacts the lips during massage, which may cause pain. In addition, at T3And T2When the ratio exceeds 6/10, if the pressing surface 13 is pushed into the oral cavity, the portion in contact with the oral cavity is reduced, and the massage effect may be reduced.
The material used for the pressing surface 13 is not particularly limited, and a thermoplastic elastomer is preferable from the viewpoint of moldability and lightweight. Among the thermoplastic elastomers, styrene-based thermoplastic elastomers, olefin-based thermoplastic elastomers, polyester-based thermoplastic elastomers, polyurethane-based thermoplastic elastomers, polybutadiene-based thermoplastic elastomers, and the like are preferable, and styrene-based thermoplastic elastomers are more preferable, from the viewpoint of achieving elasticity suitable for massaging in the oral cavity and high safety to the human body, for example. Among the styrene-based thermoplastic elastomers, for example, SEBS (styrene-ethylene-butylene-styrene) block copolymers are preferable. The above materials may be used alone, or two or more of them may be used in combination.
The pressing surface 13 preferably has appropriate elasticity in order to improve the massaging effect in the oral cavity and prevent excessive pain during massaging, for example. From such a viewpoint, the tensile strength of the material forming the pressing surface 13 is, for example, preferably 4MPa or more, more preferably 5MPa or more, and still more preferably 5.6MPa or more. The tensile strength of the material forming the pressing surface 13 is, for example, preferably 24MPa or less, more preferably 12MPa or less, and still more preferably 8MPa or less. When the tensile strength of the material forming the pressing surface 13 is less than 4MPa, the stimulation to the portion to be massaged is insufficient, and the massage effect tends to decrease. In addition, when the tensile strength of the material forming the pressing surface 13 exceeds 24MPa, excessive pain may be generated during massage.
The 300% modulus of the material forming the pressing surface 13 is, for example, preferably 0.4MPa or more, more preferably 0.7MPa or more, and still more preferably 1.0MPa or more. The 300% modulus of the material forming the pressing surface 13 is, for example, preferably 7MPa or less, more preferably 3MPa or less, and still more preferably 1.5MPa or less. When the 300% modulus of the material forming the pressing surface 13 is less than 0.4MPa, the stimulation to the massage target portion is insufficient, and the massage effect tends to be reduced. In addition, when the tensile strength of the material forming the pressing surface 13 exceeds 24MPa, excessive pain may be generated during massage.
The elongation at cutting of the material forming the pressing surface 13 is, for example, preferably 800% or more, more preferably 830% or more, and further preferably 890% or more. The elongation at cutting of the material forming the pressing surface 13 is, for example, preferably 970% or less, more preferably 950% or less, and still more preferably 920% or less. If the elongation at cutting of the material forming the pressing surface 13 is less than 800%, excessive pain may be generated at the time of massage. When the elongation at cutting of the material forming the pressing surface 13 exceeds 970%, the stimulation to the portion to be massaged is insufficient, and the massage effect tends to be reduced.
The tensile strength, 300% modulus and elongation at break are values measured in accordance with JIS K6251 (2010). The 300% modulus is a value obtained by dividing a tensile force at the time of giving an elongation of 300% to the test piece by the initial cross-sectional area of the test piece. In the measurement of the above-mentioned physical properties, the shape of the test piece may be any shape as long as it is a shape prescribed in JIS K6251. The material forming the pressing surface 13 preferably has a measured value of each physical property included in the above range when a test piece having an arbitrary shape (for example, dumbbell shape) prescribed in JIS K6251 is used.
The shank 21 is formed to extend from the head 11. The shape of the handle portion 21 is not particularly limited, but is preferably substantially rod-shaped, and for example, the same shape as that of a handle of a general toothbrush may be adopted.
A neck portion 22 having the smallest width of the shank portion 21 is formed at the end portion of the shank portion 21 on the head portion 11 side. Width W of neck 221For example, it is preferably 5mm or more, more preferably 6mm or more, and still more preferably 7mm or more. The width W of the neck portion 221For example, it is preferably 18mm or less, more preferably 12mm or less, and still more preferably 9mm or less. Width W of neck 221If the thickness is less than 5mm, the mechanical strength may be reduced, and the durability may be reduced. Further, the width W of the neck portion 221When the thickness exceeds 18mm, the flexibility is lowered, and it tends to be difficult to perform massage in the oral cavity.
In the handle 21 and the headA portion where the width of the shank 21 is the largest is provided near the end portion on the opposite side to the end portion 11. Maximum width W of shank 212For example, it is preferably 10mm or more, more preferably 13mm or more, and still more preferably 16mm or more. Further, the maximum width W of the shank 21 is2For example, it is preferably 40mm or less, more preferably 30mm or less, and still more preferably 20mm or less. At the maximum width W2Less than 10mm, and a maximum width W2When the thickness exceeds 40mm, it is difficult to hold the handle 21, and as a result, it tends to be difficult to perform a proper massage.
The user can hold the oral cavity massager 1 by, for example, holding the vicinity of the end portion of the handle portion 21 on the side opposite to the head portion 11 with the palm and 4 fingers other than the thumb while putting the thumb along the handle portion 21.
It is preferable that the handle portion 21 includes a cushioning member 23 at least in a part of a portion to be contacted by the palm or fingers of the user so that the user is less likely to feel pain even when the handle portion 21 is strongly gripped. The material used for the cushioning member 23 is not particularly limited as long as it has appropriate elasticity, and for example, the material used for the pressing surface 13 can be appropriately selected from the above materials. The cushioning member 23 preferably has a slip-preventing function to facilitate gripping by a user, and for example, the cushioning member 23 preferably has a friction coefficient larger than that of a portion of the handle portion 21 other than the cushioning member 23.
The material used for the portions of the stem 21 other than the cushioning member 23 is not particularly limited, and for example, a thermoplastic resin such as polypropylene, polyethylene terephthalate, ABS resin, or polystyrene is preferably used from the viewpoint of being able to have appropriate bendability and high mechanical strength.
As shown in fig. 2, with the intraoral massager 1, there is a curved portion 24 that protrudes upward from the lowermost position of the head 11 to the vicinity of the end portion of the handle 21 on the side opposite to the head 11. With such a configuration, it is possible to prevent the handle 21 from being strongly contacted with the lips during massage and causing pain.
As a length T in the thickness direction between the uppermost position of the head 11 and the uppermost position of the neck 22 in FIG. 24For example, it is preferably 4mm or more, and more preferably 5mm or more. Further, the length T is4For example, it is preferably 7mm or less, and more preferably 6mm or less. A length T in the thickness direction between the uppermost position of the neck portion 22 and the uppermost position in the vicinity of the end portion of the handle portion 21 on the side opposite to the head portion 115For example, it is preferably 10mm or more, and more preferably 12mm or more. Further, the length T is5For example, it is preferably 17mm or less, and more preferably 15mm or less.
A thickness T in the vicinity of an end portion on the opposite side of the head 11 in the shank 21 in FIG. 26For example, it is preferably 5mm or more, and more preferably 7mm or more. In addition, the thickness T is6For example, it is preferably 11mm or less, and more preferably 9mm or less. As a length T in the thickness direction between the uppermost position of the head 11 and the lowermost position in the shank 217For example, it is preferably 20mm or more, and more preferably 25mm or more. Further, the length T is7For example, it is preferably 42mm or less, and more preferably 30mm or less.
As T4And T7Ratio of (T)4/T7) For example, it is preferably 4/42 or more, and more preferably 7/42 or more. In addition, as T4And T7The ratio of these components is, for example, preferably 7/20 or less, and more preferably 5/20 or less.
As T5And T7Ratio of (T)5/T7) For example, it is preferably 10/42 or more, and more preferably 17/42 or more. In addition, as T5And T7The ratio of these components is, for example, preferably 17/20 or less, and more preferably 17/30 or less.
As T6And T7Ratio of (T)6/T7) For example, it is preferably 5/42 or more, and more preferably 5/20 or more. In addition, as T6And T7The ratio of these components is, for example, preferably 11/20 or less, and more preferably 1/3 or less.
By making T4～T7In the above preferred range, and/or T4/T7、T5/T7And T6/T7Within the above-described preferable range, for example, the grip portion 21 can be easily gripped, or pain caused by the grip portion 21 strongly contacting with the lips during massage can be prevented.
As a preferable specific example of the length, width and the like of each part of the oral cavity massager 1, L1 is 66mm, Sa is 25mm, L2 is 114mm, L3 is 180mm, W1Is 8mm, W2Is 18mm, T1Is 10mm, T2Is 15mm, T3Is 3.5mm, T4Is 5.5mm, T5Is 13.5mm, T6Is 8mm, T7Is 27 mm.
The user presses or rubs the pressing surface 13 of the oral cavity massager 1 against a portion to be massaged in the oral cavity, thereby massaging the oral cavity. In the case of aiming at lightening the grain of stature or lifting the corner of the mouth, for example, the shaft of the corner of the mouth, the levator labialis superior, the levator nasolabialis superior, the orbicularis oris, and the like are preferable as the parts to be massaged. In addition, when the purpose is to promote salivary secretion, for example, a sub-aural salivary gland, a submandibular salivary gland, a sublingual salivary gland, or the like is preferably used as the part to be massaged.
[ second embodiment ]
Next, an oral cavity massager according to a second embodiment of the present invention will be described. Fig. 3 is a schematic view of an intraoral massager corresponding to at least one of the embodiments of the present invention. In fig. 3, the contents described in the first embodiment can be employed as far as necessary for the portions where the same reference numerals as those in fig. 1 and 2 are given.
The head 11 and the shank 12 of the oral cavity massager 1 shown in fig. 3 are detachably attached, and fig. 3 shows a state where the head 11 and the shank 12 are separated from each other.
A fitting hole 14 formed so as to sink into the head 11 is provided at an end portion of the head 11 on the shank 21 side. A shaft member 25 is provided at the end of the handle 21 on the head 11 side. The shape of the fitting hole 14 and the shape of the shaft member 25 correspond to each other, and the head 11 can be attached to the shank 21 by fitting the shaft member 25 into the fitting hole 14.
The shaft member 25 has spherical locking members 26a and 26b at the tip and near the middle thereof, respectively. The fitting hole 14 has locking holes 15a and 15b at the deepest part and in the vicinity of the middle part, and the locking holes 15a and 15b have shapes corresponding to the locking capsules 26a and 26b, respectively. The locking capsule 26a is strongly pressed into contact with the entrance of the fitting hole 14, so that the head 11 is elastically deformed, and the shaft member 25 is inserted into the fitting hole 14. Then, the head 11 and the shank 21 are made less likely to separate from each other by receiving the locking capsules 26a and 26b in the locking holes 15a and 15b, respectively. As a result, it is easy to prevent the head 11 from separating from the shank 21 and eating the head 11 by mistake during oral cavity massage.
The number, shape, and position of the locking capsule 26 are not limited to the above examples. Similarly, the number, shape, and position of the locking holes 15 are not limited to the above examples, and may be provided so as to correspond to the locking member 26.
In the example of fig. 3, the head portion 11 is provided with a fitting hole, and the shank portion 21 is provided with a shaft member, but the present invention is not limited to this, and for example, the head portion 11 may be provided with a shaft member, and the shank portion 21 may be provided with a fitting hole.
