Signature:a Kousuke, NAGAI Date: September 19, 2008 1 CHEEK-THINNING INSTRUMENT (FIELD OF INVENTION) The present invention relates to a cheek-thinning instrument designed to burn off fat of face, particularly of sagging cheeks, by entire facial muscular exercise. (DESCRIPTION OF THE RELATED ART) Conventional face-slimming tools, for example the one disclosed by Japanese published unexamined application No. 2003-135624, are known for inserting a spring-assisted cheek-slimming tool, which expands a mouth of a user out horizontally, then the user exercises to close the tool using buccinators muscles, applying a load to cheeks or an entire face. However, the face-slimming tool as described in the above Japanese published unexamined application No. 2003-135624 is designed to burn off the fat by muscle exercise with the tool being held between the lips, therefore the tool exercises peripheral muscles of the lips, e.g. buccinators muscles, while providing small amount of exercise effect to lavator anguli oris muscles, zygomaticus major muscles and despressor anguli oris muscles, all of which work to tone up the face. The cheek-thinning instrument of the present invention is comprised of a shaft and a pair of pushing portions which can be inserted into between an upper gum and right and left cheeks or between a lower gum and the same. It can apply load to entire facial muscles, particularly lavator anguli oris muscles, zygomaticus major muscles and despressor anguli oris muscles, all of which work to tone up the face, by opening and closing exercise of lips while the shaft is being pulled upward or downward of face. The term "entire facial muscles" expressed in the present invention means the above-mentioned lavator anguli oris muscles, zygomaticus major muscles and despressor anguli oris muscles, and further include risorius muscles in central cheeks as well as buccinators muscles, forehead muscles and jaw muscles. Therefore, the present invention is as follows: (1) A cheek-thinning instrument which is comprised of a shaft and a pair of pushing portions which can be inserted into an oral cavity between an upper gum and inner surfaces of right and left cheeks or between a lower gum and the same, and which can apply load to entire facial muscles by opening and closing exercise of lips. (2) The cheek-thinning instrument according to the above (1), wherein the cheek-thinning instrument has an interconnect which interconnects the shaft with the pushing portions. (3) The cheek-thinning instrument according to either above (1) or (2), wherein a finger grip part is formed at the shaft. (4) The cheek-thinning instrument which is comprised of a shaft, a pair of pushing portions which can be inserted into an oral cavity between upper gum and inner surfaces of right and left cheeks or between lower gum and the same, and an interconnect which interconnects the shaft with the pushing portions, and which can apply load to entire facial muscles.
2 (SUMMARY OF THE INVENTION) The present invention provides the effects enumerated below. (1) The cheek-thinning instrument comprises a pair of pushing portions which can be inserted into between an upper gum and right and left cheeks or between a lower gum and the same, therefore it can be placed between a gum and cheeks with ease, and it can apply load to desired muscles with ease by pulling a shaft with fingers. Specifically, it can apply load directly to entire facial muscles by opening and closing exercise of lips while the shaft is being pulled upward or downward of face. (2) According to the above (1), the pushing portions are placeable in an oral cavity regardless of upper or lower part of it, therefore the cheek-thinning instrument can apply load individually to lavator anguli oris muscles, zygomaticus major muscles or despressor anguli oris muscles, all of which work to slim the cheeks and remove wrinkles, while the shaft is being pulled, allowing opening and closing exercise of the lips. (3) According to the above (1), the pushing portions can be put near the desired muscle(s) to slim, and by applying load directly to lavator anguli oris muscles, zygomaticus major muscles and despressor anguli oris muscles, all of which work to slim the sagging cheeks, these muscles are exercised locally and effectively burning off the fat thereof. Therefore the entire cheeks can be slimmed. (4) According to the above (1), by placing the cheek-thinning instrument of the present invention in upper and lower portions behind the lips, and by pulling the finger grip part with fingers upward or downward of the face to apply load individually to desired muscles while pursing up the lips and cheeks, entire facial muscles can be exercised. (5) Claim 2 provides the same effects as the above (1) to (3). (6) Claim 3 provides the same effects as the above (1) to (3), and because it has the finger grip part for the fingers to grip around, application of load can be made more easily. (BEST MODE FOR CARRYING OUT THE INVENTION) A first embodiment of the present invention will be described based on FIGS. I to 3. A pair of two-pronged pushing portions 2 is formed at one end of a shaft-shaped shaft 1. A finger grip part 3 is provided at the other end to help the fingers to grip around. The shape of the shaft I is preferably either bent or curved. With bending or curvature provided thereon, it can easily apply load to entire facial muscles, particularly lavator anguli oris muscles, zygomaticus major muscle and despressor anguli oris muscles, by opening and closing exercise of lips while the shaft is being pulled upward or downward of face. The shaft can be made of any kind of material such as metal or wood for example. However, it is preferably made of plastic including polypropylene, urethane, elastomer, etc. in terms of easy processability such as integral-moldability. Further preferably, tips of the pushing portions are made of smooth-surfaced and elastic material, such as rubber or silicone, which deforms a little under a load. This is to prevent interior of the oral cavity from being hurt when a load is applied on entire facial muscles, particularly lavator anguli oris muscle, 3 zygomaticus major muscle or despressor anguli oris muscle, when opening and closing exercise of the lips with the shaft being pulled upward or downward of the face, the tips of the pushing portions being inserted into between right and left inner cheek surfaces 4 and a lower gum 6. Still further preferably, the shaft 1 is made of bowable and elastic material , such as rubber or silicone, which unbends or uncurves a little under a load so as not to hurt the interior of the oral cavity. Because it is formed by such material, the pushing portions 2 and the shaft 1 can be deformed without hurting the interior of the oral cavity. The two-pronged pushing portions 2 formed as described above, is placed between the right and left inner cheek surfaces 4 and an upper gum 6 near right and left lavator anguli oris muscles 8 and zygomaticus major muscles 9, followed by, closing of the upper and lower teeth, grabbing the finger grip part3with fingers 7 to apply load upward on the lavator anguli oris muscles 8 and the zygomaticus major muscles 9, doing exercise of opening and closing the lips and entire cheeks repeatedly. The same is applicable to exercise depressor anguli oris muscles 10: the pushing portions 2 are placed between the inner cheek surfaces 4 and the lower gum 6 near right and left depressor anguli oris muscles 10, followed by, closing of the upper and lower teeth, grabbing the finger grip part3 with fingers 7 to apply load upward to the depressor anguli oris muscles 10, doing exercise of opening and closing the lips and entire cheeks repeatedly. A second embodiment of the present invention will be described based on FIGS. 4A and 4B, and is distinguished from the first embodiment by the fact that the shaft 1 is not integrally made but it has a hinge 12 at its central portion as shown in FIG. 4A, so that the cheek-thinning instrument is foldable at shaft I as shown in FIG. 4B into a compact configuration when it is not in use. The above-described structure has the same advantages as the first embodiment. It is also possible that, instead of having the hinge 12 therein, the shaft can be separated in two to be interconnected with each other with a screw when it is in use; and when it is not in use, it can be folded by loosening the screw. It is further possible to provide a mechanical joint as shown in FIG. 5, wherein a convex portion 13 is inserted into a concave portion 14 for interconnecting. When it is not in use, the mechanical joint can be disconnected to divide the instrument into two parts for compact storage. A third embodiment of the present invention will be described based on FIG. 6, and is distinguished from the first embodiment by the fact that the pushing portions 2 and the shaft 1 are interconnected with an interconnect ll. The above-described structure has the same advantages as the first and the second embodiments. A fourth embodiment of the present invention will be described based on FIG. 7, and is distinguished from the third embodiment that the finger grip part3 is formed as a ring shape. The above-described structure has the same advantages as the first and the second embodiments. Specifically, as long as the tips of the pushing portions 2 of the present invention is made of smooth-surfaced and elastic material, such as rubber or silicone, which deforms a little under a load so as not to hurt the interior of the oral cavity when a load 4 is applied to entire facial muscles, particularly lavator anguli oris muscles, zygomaticus major muscles and despressor anguli oris muscles, by opening and closing exercise of the lips while the shaft is gripped with fingers and being pulled upward or downward of the face, the pushing portions 2 are neither limited to the shapes described in FIGS. I to 6 nor to the aforementioned materials. However, material of the pushing portions 2 needs to be free of harmful heavy metals, and preferably is sterilizable by boiling water or the like. The shaft 1 of the present invention can apply load to entire facial muscles, particularly lavator anguli oris muscles 8, zygomaticus major muscles 9 and despressor anguli oris muscles 10, by opening and closing exercise of the lips while the shaft is gripped with fingers and being pulled upward or downward of the face. The shaft can be made of any kind of material such as metal or wood for example. However, it is preferably made of plastic including polypropylene, urethane, elastomer, etc. in terms of easy processability such as integral-moldability. It is neither limited to the shapes described in FIGS. 1 to 6 nor to the aforementioned materials. Further preferably, the shaft 1 is either bent or curved so that it can easily apply load to entire facial muscles, particularly lavator anguli oris muscles, zygomaticus major muscles and despressor anguli oris muscles, by opening and closing exercise of lips while the shaft is being pulled upward or downward of face. Still further preferably, it is made of bowable and elastic material, such as rubber or silicone, which unbends or uncurves a little under a load so as not to hurt the interior of the oral cavity. Still further preferably, it has a finger grip part which helps the fingers to grip around easily. The finger grip part is neither limited to the shapes described in FIGS. 1 to 6 nor to the aforementioned materials. In the present invention, it is also possible that the pushing portions 2 and the shaft I are interconnected by the interconnectll. Because the interconnectll is not meant to be put in the oral cavity any material can be used including plastic, wood and metal. However, it has a mechanical joint mechanism such as a screw to interconnect or joint the pushing portions with the shaft. The cheek-thinning instrument of the present invention is basically meant to be used in such manner that the pushing portions 2 are inserted into between an upper gum and right and left cheeks or between a lower gum and the same, however, it is also highly effective to use this instrument in such manner that either right or left portion of the pushing portions 2 being put on a risorius muscle or a buccinators muscle, upper and lower teeth being closed, finger grip part3 being gripped with fingers to apply load to the risorius muscle or the buccinators muscle where the pushing portions 2 are put on, and do exercise of opening and closing the lips and entire cheeks repeatedly . (INDUSTRIAL APPLICABILITY) (1) The cheek-thinning instrument comprises a pair of pushing portions which can be inserted into between an upper gum and right and left cheeks or between a lower gum and the same, therefore it can be placed between a gum and cheeks with ease, and it can apply load to desired muscles with ease by pulling the shaft with fingers. Specifically, it can apply load directly to entire facial muscles, particularly lavator 5 anguli oris muscles, zygomaticus major muscles and despressor anguli oris muscles, by opening and closing exercise of lips while the shaft is being pulled upward or downward of face. (2) According to the above (1), the pushing portions are placeable in the oral cavity regardless of upper or lower part of it, therefore the cheek-thinning instrument can apply load individually to lavator anguli oris muscles, zygomaticus major muscles or despressor anguli oris muscles, all of which work to slim the cheeks and remove wrinkles. (3) According to the above (1), the pushing portions can be put on peripheral of the desired muscle(s) to slim, and by applying load directly to lavator anguli oris muscles, zygomaticus major muscles and despressor anguli oris muscles, all of which work to slim the sagging cheeks, these muscles are exercised locally and effectively, burning off the fat thereof.
