Description

  The present invention relates to an oral cleaning tool that is attached to a finger and used to remove plaque.

  The oral cleaning tool according to the present invention is formed by laminating the outer edges of two large and small pieces of fabric, and an oral cleaning tool having the same configuration is disclosed in Patent Document 1 and is known. In such an oral cleaning tool of Patent Document 1, the large-sized main fabric has a semi-elliptical front end and is shaped like a spoon that is long in the front-rear direction as a whole. The small slave fabric is formed in a semi-elliptical shape that matches the outer shape of the front end portion of the main fabric. A bag having a rear-end opening that allows insertion of fingers by superimposing the subordinate fabric on the front end portion of the main fabric and then bonding the outer edges of both fabrics excluding the rear end portion of the subordinate fabric in a U-shape. The sheath part is formed.

  According to this oral cleaning tool, the sheath portion can be removed by sandwiching the portion of the main fabric that corresponds to the handle of the spoon between fingers other than the fingers to which the sheath portion is attached. An oral cleaning tool provided with the same kind of “handle” can also be found in, for example, Patent Document 2. In addition, there is a type in which a retaining hole for opening one finger other than a finger inserted in the sheath portion is formed in a handle portion extending backward from the sheath portion (see Patent Document 3).

Japanese Utility Model Publication No. 6-143 (FIG. 1) Japanese Utility Model Publication No. 4-104922 (FIG. 1) Japanese Unexamined Patent Publication No. 2000-126225 (FIGS. 1 and 2)

  In the oral cleaning device described in Patent Literature 1 and Patent Literature 2, since the “handle” is sandwiched between fingers, a large holding force cannot be obtained, and the sheath portion is caused by the acting force applied to the sheath portion during the cleaning operation. Easily slips and falls off fingers. Further, it is very difficult to perform a cleaning operation by finely moving a finger with a sheath while the “pattern” is sandwiched between fingers, which is inconvenient. This problem can be solved, for example, by providing a small retaining hole for hanging one finger on the handle as in Patent Document 3, but in that case, the size of the hand or finger is small. In accordance with the difference, it is necessary to prepare a plurality of types of products having different opening dimensions of the retaining holes and opening positions of the retaining holes, and it is inevitable that the manufacturing cost of the oral cleaning tool increases.

  An object of the present invention is to provide an oral cleaning tool that can be easily and surely attached to a finger regardless of the size of the hand or finger and that is simple in structure and suitable for mass production at low cost. .

As shown in FIG. 1, the present invention is a finger suck type oral cleaning tool that is attached to a finger 2 and includes a sheath 3 that is used for removal of plaque. As shown in FIG. 2 and FIG. 3, such an oral cleaning tool is composed of a main fabric 5 that is long in the front-rear direction and a sub-fabric 6 that matches the front end shape of the main fabric 5. The bag-like sheath portion 3 having the rear end opening 10 for inserting fingers is formed by binding the outer edges of both fabrics 5 and 6 excluding the rear end portion of the sub-fabric 6 after being stacked on the portion. is there. Then, a plurality of fingers other than the index finger 2b inserted in the sheath part 3 are hung on the center part in the left-right direction of the main fabric 5 closer to the rear side than the sheath part 3, and the sheath part 3 falls off from the index finger 2b. The main body 5 has a slit 15 that is long in the front-rear direction, and a rear end portion from the front-rear center portion of the main fabric 5 is a ring body 17 having a slit 15 that is long in the front-rear direction.

  The main fabric 5 and the sub-fabric 6 can be cotton, rayon, PET, PP, PE, acrylic, or a nonwoven fabric composed of these composite fibers, or a composite nonwoven fabric composed of these and other fibers. The “slit 15” mentioned here is a concept including not only a long slit formed in the front and rear as shown in FIG. 2 and FIG. 3 but also a long opening in the front and rear formed by punching. What is necessary is just to be able to hang a plurality of fingers 2. The outer shape of the main fabric 5 may be an ellipse that is long in the front-rear direction as shown in FIG. 2 or a rectangular shape that is long in the front-rear direction. . Examples of the method for binding the two fabrics 5 and 6 include heat welding, bonding with an adhesive, and sewing. This oral cleaning tool is suitable as a cleaning tool for the human oral cavity or as a cleaning tool for the oral cavity of a pet such as a dog or a cat. The cleaning tool can also be used for cleaning the nose and ears.

Specifically, as shown in FIG. 1, the index finger 2b is inserted into the sheath 3 from the rear end opening 10 side, and another finger 2 including at least the thumb 2a other than the index finger 2b is slit 15. When the slit 15 is expanded in the left-right direction of the main fabric 5 with these fingers 2, the sheath 3 is pulled to the palm side and the palm 3 is directed to the palm side. In this configuration, the front end of the slit 15 is positioned in the vicinity of the rear end opening 10 of the sheath 3 so that the acting force F can be applied.

Further, as shown in FIG. 5, the present invention includes a first sheath portion 21 attached to the index finger 2b and a second sheath portion 22 attached to the thumb 2a, and these two sheath portions 21 and 22 are used. An oral cleaning tool for removing plaque. As shown in FIGS. 6 and 7, this oral cleaning tool is formed by bonding two large and small pieces of fabric 25 and 26. The large main fabric 25 includes a first mounting piece 28 that constitutes the first sheath portion 21 and is long in the vertical direction, a vertically long hanging piece 29 that is continuous with the rear end portion of the first mounting piece 28, The first mounting piece 28 includes a second mounting piece 30 that is formed to project obliquely forward from the base end of the hooking piece 29 side of the first mounting piece 28 and constitute the second sheath portion 22. Small従生land 26, the first and second mounting pieces 28, 30 of the outer shape and match, is formed in a bifurcated shape. After the subordinate fabric 26 is overlaid on the main fabric 25, the outer edge excluding the rear end portion of the subordinate fabric 26 is bonded to the outer edge of the main fabric 25, so that the rear end opening 31 that allows insertion of the index finger 2 b and the thumb 2 a is formed. The bifurcated glove-shaped first and second sheath portions 21 and 22 are formed. Then, the latch piece 29 is hung on the wrist 41 as shown in FIG. 1 at the center portion in the left-right direction of the latch piece 29, and the first and second sheath portions 21 and 22 are detached from the fingers 2b and 2a. A slit 37 for blocking is provided long in the front-rear direction.

  The main fabric 25 and the sub-fabric 26 can be cotton, rayon, PET, PP, PE, acrylic, a non-woven fabric made of these composite fibers, or a composite non-woven fabric of these and other fibers. The “slit 37” mentioned here is a concept including not only a long slit formed in the front and rear as shown in FIGS. 6 and 7, but also a long opening in the front and rear formed by punching. What is necessary is just to be able to hang the wrist 41. Examples of the method for binding the two fabrics 25 and 26 include heat welding, bonding with an adhesive, and sewing. This oral cleaning tool is suitable as a cleaning tool for the human oral cavity or as a cleaning tool for the oral cavity of a pet such as a dog or a cat. The cleaning tool can also be used for cleaning the nose and ears.

  A latching piece 35 having a slit 36 for hanging the middle finger 2c can be formed so as to protrude from the front and rear midway part of the side surface of the first sheath part 21.

  As shown in FIGS. 4 and 8, the main fabrics 5 and 25 and the sub-fabrics 6 and 26 are assumed to have the nonwoven fabric 7 as a base, and the inner surface of the nonwoven fabric 7 can be subjected to waterproof film processing. In these drawings, reference numeral 9 denotes a waterproof film. Specific examples of the film 9 include thermoplastic films such as PP and PE.

  The outer surface of the nonwoven fabric 7 is preferably uneven. Examples of the method for forming irregularities include a method of meshing fibers in a mesh shape by a water jet method (mesh processing), embossing, and the like.

  According to the first aspect of the present invention, as shown in FIG. 1, one finger is inserted into the sheath 3 and the plural fingers other than the fingers 2 b inserted into the sheath 3 are inserted. The finger 2 is hooked on the periphery of the slit 15 formed long in the front-rear direction on the main fabric 5. In such a latching mounting posture, cleaning is performed by rubbing the target site such as teeth and gums using the sheath 3. At this time, since the oral cleaning tool 1 is securely hooked by the plurality of fingers 2 hung on the slit 15, the sheath part 3 is displaced during use or falls off the finger 2b on which it is attached. There is nothing.

  In addition, since a plurality of fingers (thumb 2a, etc.) are hung on one slit 15 long in the front and back provided in the main fabric 5, regardless of the size of the hands or fingers, FIG. It is possible to easily take the hanging mounting posture as shown. Thus, as in Patent Document 3, various products having different opening positions and opening dimensions according to the size of the hands and fingers, which could not be avoided in the form of having a small retaining hole, are available. The problem of increase in manufacturing cost due to the preparation can be solved, and the cost of the oral cleaning tool 1 can be reduced.

  Further, as shown in FIG. 1, a plurality of fingers including the thumb 2 a are hung on the periphery of the slit 15, and the slit 15 is expanded and expanded with these fingers 2 a, so that Therefore, it is possible to prevent the sheath portion 3 from coming off from the index finger 2b, the position shift, and the like well. Above all, with this acting force F, the sheath 3 can be strongly adhered to the tip abdomen of the finger inserted into the sheath 3 (for example, the index finger 2b), so even when a large force is applied to the sheath 3, There is no wrinkle on the sheath 3, and therefore the practical convenience of the oral cleaning tool 1 can be remarkably improved.

  When the waterproof fabric is applied to the inner surfaces of the main fabric 5 and the sub-fabric 6, it is possible to prevent the fingers (such as the index finger 2b) inserted into the sheath portion 3 from getting wet during use. Further, since the elastic force can be applied to the ring body 17 at the periphery of the slit 15 which has been expanded, due to the original shape restoring force of the film 9, the sheath 3 can be moved toward the palm side by a slight expansion operation. It is also excellent in that the acting force F can be applied. Compared to the configuration in which the fabrics 5 and 6 are formed only by the nonwoven fabric 7, the fabrics 5 and 6 can be reinforced with the backed film 9, so that the sheath portion 3 may be broken during use, or may be rotated during the expansion operation. There is no problem that the body 17 is torn.

  If the outer surface of the main fabric 5 is uneven, plaque can be scraped off using the step between the concave and convex portions, and the cleaning efficiency is improved. Appropriate stimulation can be given to the gingiva. However, it is sufficient that the unevenness is provided on the outer surface of the sheath portion 3 of the main fabric 5, that is, on a portion subjected to a cleaning operation. In particular, when the concave portion has an opening shape, the peripheral edge of the opening acts like a cutting blade, and plaque and the like can be scraped off well. That is, when the oral cleaning tool 1 is applied to the tooth surface, the concave portion takes a posture form in which the opening direction is substantially perpendicular to the tooth surface. By moving the surface so as to rub, it is possible to remove the plaque by pulling the plaque around the peripheral edge of the opening of the recess and peeling the plaque away.

  According to the third aspect of the present invention, as shown in FIG. 5, the slit 37 of the latching piece 29 is expanded, all fingers are passed through the slit 37, and the ring body 39 is hung on the wrist 41. Insert the thumb 2 a into the second sheath 22 and the index finger 2 b into the first sheath 21. Then, in such a latching mounting posture, cleaning is performed by rubbing target portions such as teeth and gums using the sheath portions 21 and 22. At this time, since the oral cleaning tool 1 is securely hooked by the wrist 41 hung on the ring body 39 through the slit 37, the sheath portions 21 and 22 do not fall out of the index finger 2b and the thumb 2a during use. . Above all, it is possible to prevent falling off regardless of the finger posture at the time of the cleaning operation, so that the cleaning operation can be performed by freely moving the finger 2 and is excellent in practical convenience.

  If the latching piece 35 having the slit 36 for hanging the middle finger 2c is formed so as to protrude from the front and rear midway part of the side surface of the first sheath part 21, the first sheath part 21 can be prevented from shifting. The operability can be improved.

  When the waterproof fabric is applied to the inner surfaces of the main fabric 25 and the sub-fabric 26, it is possible to prevent the fingers (for example, the index finger 2b) inserted into the sheath portions 21 and 22 from getting wet during use. Compared to the configuration in which the fabric 25/26 is composed of the nonwoven fabric 7 alone, the fabric 25/26 can be reinforced with the backed film 9, so that the first and second sheath portions 21/22 are broken during use. There is no such trouble.

  If the outer surface of the main fabric 5 is uneven, plaque can be scraped off using the step between the concave and convex portions, and the cleaning efficiency is improved. Appropriate stimulation can be given to the gingiva. However, it is sufficient that the unevenness is provided on the outer surfaces of the first and second sheath portions 21 and 22 of the main fabric 25, that is, on the portion subjected to the cleaning operation. In particular, when the concave portion has an opening shape, the peripheral edge of the opening acts like a cutting blade, and plaque and the like can be scraped off well. That is, when the oral cleaning tool 1 is applied to the tooth surface, the concave portion takes a posture form in which the opening direction is substantially perpendicular to the tooth surface. By moving the surface so as to rub, it is possible to remove the plaque by pulling the plaque around the peripheral edge of the opening of the recess and peeling off the plaque.

(First embodiment)
1 to 4 show a first embodiment of the oral cleaning tool of the present invention. The oral cleaning tool 1 is a finger sac type cleaning tool that is attached to a finger 2 and includes a sheath 3 that is used for removal of plaque, and corresponds to claims 1 and 2 of the present invention. ing. In addition, in FIG. 1, the usage form which mounted | wore the index finger 2b with the sheath part 3 is shown.

  As shown in FIGS. 2 and 3, the oral cleaning tool 1 includes an elliptical main fabric 5 that is long in the front-rear direction and a semi-elliptical subfabric 6 that matches the outer shape of the front end of the main fabric 5. Is done. As shown in FIG. 4, these two fabrics 5 and 6 have a two-layer structure in which a waterproof film 9 made of LLDPE (medium density polyethylene) is attached to one surface of a non-woven fabric 7 made of cotton. It is. Then, after superposing the follower fabric 6 on the front end portion of the main fabric 5 so that the waterproof films 9 and 9 face each other, the outer edges of both fabrics 5 and 6 excluding the rear end portion of the follower fabric 6 are U-shaped. The bag-shaped sheath portion 3 having the rear end opening 10 that allows insertion of one finger (for example, the index finger 2b) is formed by binding in a shape. Here, both fabrics 5 and 6 are bonded together by heat sealing.

  2 and 3, reference numeral 11 denotes a heat-welded portion. Here, the rear end portion of the U-shaped foot on the outer edge of the sub-dough 6 is subjected to heat sealing processing, and the rear end opening 10 is formed. Slits 12 and 12 are formed on both left and right edges of the facing fabrics 5 and 6. If the slits 12 and 12 are formed on both the left and right edges of the rear end opening 10 as described above, the rear end opening 10 can be opened wider than in the case where the slit 12 is not provided, so that the finger (for example, the index finger 2b) The operation of mounting the sheath 3 on the other hand, in other words, the operation of inserting the finger (index finger 2b) into the sheath 3 can be performed smoothly.

  The nonwoven fabrics 7 of both the fabrics 5 and 6 are made of cotton fibers entangled by a water jet method so that convex portions having a large thickness dimension and concave portions having a smaller thickness dimension are arranged in a matrix.

As shown in FIG. 2 and FIG. 3, a central slit in the left-right direction of the main fabric 5 located closer to the rear than the sheath 3 is provided with a long slit 15 in the front-rear direction and a long slit 15 in the front-rear direction. The front end of the slit 15 is located in the vicinity of the rear end opening 10 of the sheath 3. That is, the main fabric 5 has a ring body 17 having a slit 15 which is long in the front-rear direction from the front-rear center portion to the rear end portion.

  The oral cleaning tool 1 as described above first inserts the index finger 2b into the sheath 3 from the rear end opening 10 side, and then inserts other fingers including at least the thumb 2a other than the index finger 2b into the periphery of the slit 15. The slit 15 is expanded and deformed in a stretched manner with these fingers. In FIG. 1, the thumb 2a and the little finger 2e are hung on the periphery of the slit 15, and the two fingers 2a and 2e are expanded so that the slit 15 is pinched. By such an expansion operation, an action force (F: indicated by a white arrow in FIG. 1) that is directed toward the palm side (rear side) can be applied to the sheath portion 3, so that the sheath portion 3 falls off from the index finger 2b. In addition, misalignment can be well prevented. Above all, with this acting force F, the sheath 3 can be tightly attached to the tip abdomen of the index finger 2b, so even when a large force is applied to the sheath 3, the sheath 3 is not wrinkled, Accordingly, the practical convenience of the oral cleaning tool 1 can be remarkably improved.

  In addition, by operating the slit 15 that is long in the front and back provided in the main fabric 5 with a plurality of fingers (thumbs 2a to 2e), an acting force F that is directed toward the palm side on the sheath 3 is provided. Since the specifications are given, the wearing posture as shown in FIG. 1 can be easily taken regardless of the size of the hand or the finger. Thus, as in Patent Document 3, various products having different opening positions and opening dimensions according to the size of the hands and fingers, which could not be avoided in the form of having a small retaining hole, are available. The problem of increase in manufacturing cost due to the preparation can be solved, and the cost of the oral cleaning tool 1 can be reduced.

  Since the two doughs 5 and 6 are bonded together, it is suitable for mass production at low cost. Further, since the slit 15 is formed by cutting, for example, processing is easy and the manufacturing cost can be reduced as compared with a configuration in which an oval punched portion is provided at the center of the main fabric 5. Since the manufacturing process for removing the waste applied to the punched portion is unnecessary, the manufacturing cost can be reduced in this respect.

  When the waterproof film 9 is affixed to the inner surface of the nonwoven fabric 7, it is possible to prevent the fingers (for example, the index finger 2b) inserted into the sheath 3 from getting wet during use. In addition, since the elastic force can be applied to the expanded ring body 17 due to the original shape restoring force of the film 9, a large acting force F toward the palm side is applied to the sheath portion 3 by a slight expansion operation. Can be given. Compared to the configuration in which the fabrics 5 and 6 are formed only by the nonwoven fabric 7, the fabrics 5 and 6 can be reinforced with the backed film 9, so that the sheath portion 3 may be broken during use, or may be rotated during the expansion operation. There are few problems that the body 17 is torn.

  The non-woven fabric 7 located on the outer surfaces of the two fabrics 5 and 6 and used for the cleaning operation is entangled so that convex portions having a large thickness dimension and concave portions having a smaller thickness dimension are arranged in a matrix. If it is, the plaque can be scraped off using the step between the concave and convex portions, so that the cleaning efficiency is improved. Appropriate stimulation can be given to the gingiva. However, it is sufficient that these uneven portions are provided on the outer surface of the sheath portion 3 of the main fabric 5. In particular, when the concave portion has an opening shape, the peripheral edge of the opening acts like a cutting blade, and plaque and the like can be scraped off well. That is, when the oral cleaning tool 1 is applied to the tooth surface, the concave portion takes a posture form in which the opening direction is substantially perpendicular to the tooth surface. By moving the surface so as to rub, it is possible to remove the plaque by pulling the plaque around the peripheral edge of the opening of the recess and peeling the plaque away.

  In the above embodiment, the slit 15 may be an opening that is long in the front-rear direction instead of being cut. However, as described above, it is advantageous in terms of cost to form the slit 15 by cutting.
