DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rubbing device for the oral cavity which is worn on a finger to perform wiping, wiping, application, putting, massage, etc. of the inside of the oral cavity and lips.

[0002]

2. Description of the Related Art Conventionally, various types of rubbing devices made of a fiber material have been proposed as rubbing tools for rubbing a target area for the purpose of wiping the mouth or lips, treating makeup or treating injuries. Have been. Specific examples include wet tissues, wet wipes, cleaning liquid impregnated tissues,
Fungicide impregnated tissue, dry sheet, gauze, etc. Such a rubbing tool needs to be firmly fixed to a finger and to be able to follow a fine movement of the finger in order to be able to properly process a fine portion inside the oral cavity.

[0003] In order to solve the above-mentioned problems, there have been proposed some types of rubbing tools which are used by being fixed to a finger by pasting it on a finger or fitting it on a finger.
For example, as a rubbing tool for cleaning the inside of an oral cavity, there is a tape-shaped device that is attached to a finger (Japanese Patent Application Laid-Open No. 61-44807, Japanese Patent Application Laid-Open No. 10-99352). Above all, there have been proposed a large number of types which are easy to be worn on a finger and which are easy to move, which are formed in a tubular shape or a finger-sack shape and into which a finger is inserted and used (Japanese Patent Application Laid-Open No. 61-20 / 1986).

[0004] In general, the shape of the rubbing tool used in the oral cavity is such that when the rubbing tool is circulated in the oral cavity, soft tissues such as gums, mucous membranes, lips and the like are stimulated, and pain or discomfort is felt. ,
It is devised that the tip portion corresponding to the fingertip is rounded into the shape of a finger so as not to make a cut or the like (Japanese Patent Laid-Open No. 611-2).
0548, JP-A-9-220243, JP-A-61-43220, JP-A-64-19417, JP-A-1-119624, JP-A-4-44.

No. 118029, Japanese Utility Model Publication No. 5-34923,
Japanese Utility Model Laid-Open No. 5-68510, Japanese Utility Model Laid-Open No. 7-44292, and Registered Utility Model No. 3035790.

On the other hand, when industrially producing a cylindrical or finger-sucking rubbing tool, a soft plastic material is melted and injected into a cylindrical or finger-suck-shaped mold, or one piece is molded. Alternatively, it is formed by a method of laminating a plurality of sheets of plastic, cloth, nonwoven fabric, or the like in a tubular shape. In the latter method, the sheet can be formed into a tubular shape or a finger-sack shape by bonding the joining edges of the sheets superposed in a tubular shape along the shape of the finger. At this time, in addition to chemical bonding using an adhesive or the like, various methods such as fusion by heat, sewing using a thread, mechanical fitting using an ultrasonic sewing machine, and the like are used as a bonding method of the sheet at this time. Can be

In the manufacturing method, the former method of injection molding is preferable because it can be processed into various shapes.
When a rubbing tool having a rounded tip is obtained as a rubbing tool having a good feeling of use in the oral cavity, it can be easily manufactured by molding it with a soft plastic. The rubbing tool mainly made of soft plastic has a poor usability due to lack of water absorption and elasticity, and is difficult to impregnate with a chemical such as a cleaning liquid.

For this reason, it can be said that a rubbing tool using a nonwoven fabric or a woven fabric is preferable as a material. However, when a rubbing tool is manufactured using a sheet made of such a nonwoven fabric or a woven fabric, the rubbing tool may be used. When trying to make the tip round, the part of the sheet that touches the tip of the rubbing tool must be cut into an arc shape, and this arc-shaped joining edge must be glued. And the production efficiency is low.

Therefore, instead of forming the tip of the rubbing tool into an arc shape as described above, if the rubbing tool is formed into a linear cut shape, the linear joining edge of the sheet may be adhered to the rubbing tool, so that the manufacturing is simple. And there is little waste. However, when the tip of the rubbing tool is formed in a straight line as described above, a hard and sharp edge is formed at the corner where the sheet bonding portion on the side surface of the rubbing tool and the sheet bonding portion at the tip end intersect. Will be. Even if the bonding edge of the sheet is left open without bonding at the leading end of the rubbing tool, the edge as described above is formed at the position of the tip corner of the rubbing tool by the leading end of the sheet bonding portion on the side surface. Is formed.

[0009] When the rubbing tool thus made is put on a finger and moved in the oral cavity, sharp edges stimulate soft tissues such as gums, mucous membranes, lips, etc., causing pain and discomfort. There is a disadvantage that a cut is caused. For this reason, a cylindrical or finger-sucking rubbing tool manufactured by a laminating method has been desired which is gentler in the oral cavity and has a good usability.

[0010]

SUMMARY OF THE INVENTION The technical problem of the present invention is to provide an oral cavity rubbing device made by laminating sheets in a tubular shape and bonding the bonding edges together. By configuring so that a hard and sharp edge is not formed at the end, the gum due to the edge at the time of rubbing,
The purpose is to prevent damage to soft tissues such as mucous membranes and lips.

[0011]

In order to solve the above-mentioned problems, an oral rubbing tool according to the present invention comprises a sheet rim having a length of 1 mm or more in which the joining edge is not adhered to a part of a sheet joining edge located on the side surface of the cylinder. One or more adhesive portions are formed, and the non-adhesive portion is provided at least at an end near the tip of the cylinder.

In the rubbing tool having the above-described configuration, since the above-described non-adhesive portion is provided at the leading end portion of the sheet bonding portion, a hard and sharp edge is not formed at the tip corner of the rubbing tool. Damage to soft tissues such as gums, mucous membranes, and lips due to edges during rubbing can be reliably prevented.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to the drawings. FIG. 1 shows a first embodiment of a rubbing tool according to the present invention. This rubbing tool 1A
Is a method in which one rectangular sheet 2 made of a flexible material is rolled up or folded into two to be overlapped in a cylindrical shape, and both joining edges of the sheet 2 are adhered to each other by appropriate means on the side surface of the tube. Thereby, the front end portion is formed in a cylindrical shape with both ends open in a shape cut straight in a direction perpendicular to the axis of the cylinder, and at this time, both joining edges of the sheet 2 are rubbed by the rubbing tool 1A. This is such that the end portion of the rubbing tool 1A does not partially adhere without being adhered over the entire length. That is, the non-adhesive portion 4 where both joining edges are not adhered to each other is partially formed at the tip portion of the rubbing tool 1, and the other portion is used as the adhesive portion 3. The formation of 4 prevents a hard and sharp edge from being formed at the corner of the tip of the rubbing tool 1. The length of the non-adhesive portion 4 is 1 mm or more, preferably 3 to 5 mm or slightly longer.

As shown in FIG. 2, for example, the above-mentioned rubbing tool 1A is fitted to one or a plurality of fingers such as an index finger and a middle finger, and rubs the inside of the oral cavity and the lips. Since there is no hard and sharp edge at the corner, it does not damage soft tissues such as the oral mucosa and the tongue, and does not give an unpleasant feeling.

The above rubbing tool can be formed in various sizes according to the purpose of use. For example, when the purpose is to rub a narrow place such as in the oral cavity, it is formed in a size that allows one finger to enter. In this case, the size of the entire rubbing tool is preferably about 20 × 30 mm to 50 × 200 mm. When the purpose is to rub the front teeth and the lips, it is preferable that the rubbing tool has a width of 30 × length 3 in which a plurality of (for example, two to three) fingers can enter.
It is preferable that it is formed to have a size of about 0 mm to width 150 × length 200 mm.

On the other hand, the method of bonding the bonding edges of the sheet 2 to each other includes a method of fusing by heat, a method of bonding with an adhesive, a method of sewing with a thread, a method of bonding with an adhesive tape, an ultrasonic sewing machine, For example, a method such as fitting by using the above method is preferably used.

The material of the flexible material forming the sheet 2 is not particularly limited, and synthetic fibers such as polyester, polypropylene, polyethylene, rayon, nylon, acrylic, etc.
A fibrous material such as a woven fabric or a nonwoven fabric formed by using natural fibers such as cotton, pulp, and silk alone or by mixing a plurality of natural fibers can be used. Alternatively, a water-repellent sheet made of natural rubber, synthetic rubber, silicon, vinyl, or the like other than the fibrous material can be used.

[0018] Above all, oral or lip cleaning, massage,
For the purpose of drug application, it feels good and absorbs water,
A fibrous material made of rayon, cotton, silk, paper, pulp or the like having excellent water retention properties is preferably used. When using a water-absorbing or water-permeable material, it is desirable to coat the inner surface of the rubbing tool with a water-impermeable sheet or film such as polyethylene, polypropylene, or vinyl. While preventing the finger from getting wet inside, when forming the rubbing tool with the sheet,
Since fusion by heat can be performed at a lower temperature, curing of the fibrous material at the time of molding by heat can be prevented, and a rubbing tool having a good touch can be produced.

The rubbing tool may be impregnated with an aqueous or non-aqueous liquid composition by immersion or spraying if necessary. As the liquid composition suitably used when the rubbing tool is used for cleaning the mouth, water, alcohol, humectant, abrasive, surfactant, flavor, sweetener, pH adjuster, preservative, Fungicides, medicinal components and the like. The weight ratio between the rubbing tool and the liquid composition in this case is
1: 0.1 to 1:50 is preferred, and more preferably 1: 1:
0.2 to 1:30. The ratio of the liquid composition is 1: 0.
If it is less than 1, the effect of removing dirt on the tooth surface or the like becomes insufficient because the medicine is not sufficiently released from the rubbing tool, and 1: 5.
If it is more than 0, the excess drug will flow into the oral cavity and the feeling of use will be significantly reduced. In addition, since saliva is secreted, the retention of the drug will be reduced and the cleaning effect will be reduced.

FIG. 3 shows a second embodiment of the rubbing tool according to the present invention. In the rubbing tool 1B of the second embodiment, the non-adhesive portion 4 is formed not only at the tip end of the rubbing tool 1B but also at one or a plurality of positions at an intermediate position on the side surface. The configuration is different from that of the first embodiment. Other configurations are the same as those of the first embodiment.

This rubbing tool 1B is used by being directly fitted on a finger as in the case of the rubbing tool 1A of the first embodiment. However, in addition to such a method of use, as shown in FIG. Bending at the position of the intermediate non-adhesive portion 4 and fitting it to a finger for use, or as shown in FIG. Figure C
As shown in (2), it is also possible to use such a method that two fingers are supported and pressed against a target part to rub. In this case, since the rubbing tool 1B is bent at the position of the non-adhesive portion 4, a hard and sharp edge is not formed at the end of the bent portion as in the case of bending at the position of the adhesive portion 2. Excellent in safety during use.
