The cleaning device (1) of the present invention will be described in detail mainly for the denture (9) according to FIGS.
When cleaning the denture (9) with chemicals, it is necessary to re-clean with a brush or a brush after that, and cleaning with a brush with a brush is too time consuming to remove dirt that is difficult to apply force, By forming a large protrusion (T1) and a small protrusion (T2) on a cylindrical object made of an elastic material, which tends to become rough, the teeth (9) are rubbed. This is a denture cleaning device (1) that can clean dirt adhering to the dentures (9) with a simple operation.
The smooth surface (M) is a gentle portion where the projection size (T1) and projection size (T2) are not provided in the tip (2) of the present invention. In addition, although the cleaning instrument (1) of this invention is suitable for a denture (9), it is suitable also for cleaning other than a denture (9).

A cleaning instrument (1) according to the present invention is a cleaning instrument (1) comprising a distal end portion (2) of a cylindrical body and a grip portion (3) connected to the rear portion of the distal end portion (2). A protrusion size (T1) is provided at the center of the edge (2a) of the tip (2) made of a rod-like body, and the protrusion size (T2) is small so as to surround the periphery of the protrusion size (T1). ), And a cleaning instrument (1) having a small protrusion (T2) on the side edge (2b) of the tip (2). Of course, it is also suitable for cleaning other than the dentures (9).

In addition, by constructing a large protrusion (T1) and small protrusion (T2) on a cylindrical object made of an elastic material, for example, the dirt adhering to the denture can be cleaned by rubbing the denture (9). This is a denture cleaning tool (1) that can be used.
The small protrusion (T2) provided on the side edge (2b) is provided only on the upper surface (4) of the side edge (2b), and the lower surface (5) is a smooth surface (M). For example, it is a tool suitable as a cleaning tool for dentures (9).
The present invention shortens the labor and time, and ensures cleanliness. Hereinafter, the cleaning object (1) of the present invention will be described in detail as a denture (9).

  Further, the smooth portion of the denture (9) is rubbed with the smooth surface (M) of the present invention, and the convex portion (T1) and the small projection (T2) are utilized for the uneven portion such as the tooth portion and the depression. By doing so, it can be cleaned smoothly. Further, the plastic which is the main component of the denture (9) does not hurt even if it rubs against the elastic body, and does not wear out. Further, the comrades can reliably adhere and scrape off dirt. Therefore, the cleaning device of the present invention is excellent in rubbing. What is excellent in the rubbing condition here refers to a phenomenon in which the feeling of scum remaining with dirt remains quickly, and the sound when rubbing quickly changes from gu, gu to cucumber.

Further, the smooth surface (M) of the present invention will be described in detail with respect to the smooth surface (M). The smooth surface (M) of the present invention is a smooth surface composed of fine irregularities. The fine irregularities are not shown, but have gentle and extremely fine irregularities. . The height of the uneven peaks and the depth of the valleys are preferably about 0.01 mm to about 0.05 mm.

In addition, cleaning with chemicals requires time to soak and then re-cleaning with a brush, and cleaning with a toothbrush with a brush takes too much time to remove dirt, making it difficult to clean. By forming a large protrusion (T1) and small protrusion (T2) on a cylindrical object made of an elastic material, the tooth is rubbed into the denture (9). This is a denture cleaning device (1) that can clean dirt adhering to (9).
The tip (2) of the present invention may be not only a cylinder but also a square, hexagon, or the like.

Further, the tip (2) is made of a resilient elastic body, so that the adhesion to the denture (9) can be increased and the dirt can be scraped off. As the elastic body, rubber, silicon or the like is suitable.
The denture (9) has a soft denture (7) part and a gentle part (6) that is the base of the denture (9). To clean these parts thoroughly, In addition, a structure composed of a combination of the flat surface (M) and the protruding portion, that is, the large protrusion (T1) and the small protrusion (T2) is indispensable.

Further, the projection size (T1) is most preferably a conical shape, but may be a cylindrical shape or other column state. In the case of a conical shape, the height (H1) is preferably about 3 to 6 mm as the size of the longitudinal section. The width W1 is preferably 2 to 3 mm.

Further, the small protrusion (T2) is most preferably a conical shape, but may be a cylindrical shape or other column state. In the case of a conical shape, the height (H2) is preferably about 1 to 2 mm as the size of the longitudinal section. The width W2 is preferably 0.7 to 1.0 mm.

Also, no cleaning liquid or dough is used, and dirt is scraped off with an elastic body, so it does not take time and money, and the cleaning status can be confirmed with fingers, eyes, and sound, so it is safe and comfortable, and time Because it can be done in a short time, it does not cause stress.

Moreover, the axial direction front-end | tip direction of the front-end | tip part (2) of a denture cleaning tool (1) is not open | released, the other end is open | released, and the insertion hole (S) is provided. The tip part (2) is made of an elastic body, and a rod-like object to be the grip part (3) is simply inserted into the insertion hole (S), so that it is easy to construct and technically and inexpensively. I can do it. However, attachment of the grip part (3) is not limited to the insertion method. Adhesive means or mechanical attachment means may be used. The shape of the grip portion (3) may be a rod shape as shown in the figure, but it may be a spherical body devised for easy gripping, or any other object.
The smooth surface (M) is a curved surface portion having no projection size (T1) and no projection size (T2).

  Also, hold the denture (9) in one hand, hold the denture cleaning device (1) of the present invention with another hand, and rub the entire denture (9). The gentle part is rubbed with the flat part of the present invention, that is, the smooth surface (M), and the denture (7) part of the denture (9) is the protrusion large (T1) and the small protrusion (T2). By using it, you can clean your dentures without stress. When cleaning, it is best to use running water.

In addition, at the protrusion size (T1), the portion (6) that becomes the base of the denture (9) or the comparatively gentle part of the fastener (8) and the denture (7) of the denture (9) is rubbed to make contact with the gum Clean the comparatively gentle part of (9). In the small protrusion (T2), the denture (7) of the denture (9) and the narrow portion of the denture (7) are cleaned. On the smooth surface (M), the entire denture (9) is cleaned. As the cleaning progresses and the stains are removed, the sound of the denture (9) cleaning changes from gu, gu to cucumber, cucumber due to the rubbing of the denture (9) and the denture cleaning device (1) of the present invention. Because it comes, you can check the degree of cleaning and the location of the part where the dirt is not removed.

In addition, when the sound is gu, it is a case where dirt remains, and when the sound is cucumber, cucumber, the dirt is removed and clean.
When the teeth (9) are rubbed with a finger during cleaning, the place where the dirt is removed disappears, so that the degree of the dirt can be confirmed even in this operation.
In this plan, the tooth (9) is picked up and cleaned while looking at it, so that it is possible to know where it is not cleaned and clean it reliably.

Moreover, about 12-20 mm in diameter is suitable for the thickness of a front-end | tip part (2), and about 10-16 mm of long diameters are suitable about the thickness of the grip part (3). As for the length, about 200 mm to 260 mm is suitable for easy holding. However, it is not limited to these dimensions. The depth of the insertion hole (S) is preferably about 10 to 50 mm. Moreover, the effective length of the grip part (3) which protruded from the front-end | tip part (2) becomes about 150-250 mm, and is suitable for cleaning workability | operativity.

  Further, the tip of the large protrusion (T1) or the small protrusion (T2) is most preferably a conical point, but a slightly rounded tip is also preferable.

  Next, tests were conducted on examples and comparative examples, and are shown in Table 1.

  Example 1 will be described. The columnar tip (2) had a thickness of 16 mm and a length of 50 mm. A silicon pipe having a hardness of 60 degrees (rubber hardness according to JIS, K, 6253) was used. The depth of the insertion hole (S) of the tip (2) was 40 mm. The thickness of the gripping rod (3) was set to 12 mm, which was slightly narrower than the tip (2). Since the length is about 150 mm to 250 mm, it is easy to hold, so the grip part (3) having a length of 240 mm is inserted into the insertion hole (S) having a depth of 40 mm in the tip part (2) having a length of 50 mm and the grip part (3) The length was 200 mm. The height difference between the peaks and valleys of the fine irregularities provided on the smooth surface (M) was 0.02 mm.

  In Example 2, a pipe made of butyl rubber having a hardness of 60 degrees was used for the cylindrical tip portion (2). Others were the same as in Example 1.

  In Example 3, a silicon pipe having a hardness of 50 degrees was used for the cylindrical tip portion (2). Others were the same as in Example 1.

  In Example 4, a silicon pipe having a hardness of 40 degrees was used for the cylindrical tip portion (2). Others were the same as in Example 1.

  In Comparative Example 1, a urethane resin foam pipe having a hardness of 30 degrees was used for the cylindrical tip portion (2). Others were the same as in Example 1.

  In Comparative Example 2, a silicon pipe having a hardness of 70 degrees was used for the cylindrical tip portion (2). Others were the same as in Example 1.

  Next, the test method will be described. While holding the denture in one hand and holding the cleaning device of the present invention in another hand, reciprocate about 100 mm as a guide while bringing the denture and the cleaning device into close contact. The number of reciprocations at the same position was about 20, and the force was applied by one's hand so that the force was applied as evenly as possible. In addition, the degree of dirt removal is determined by a sensitivity test and visually determined, touched with a finger to determine whether there is a lingering feeling. Judgment was made by changing to cucumber.

The explanation of the evaluation is as follows.
◎ Extremely good (no visual stains, no sensation of finger feeling, sound is also cucumber, cucumber)
○ Good (visually unobtrusive stains are not conspicuous, there is no slimy feeling with fingers, and the sound is also cucumber and cucumber)
△ Slightly poor (Slight visual stains are present, the finger feels a little slimy, and the sound is a little ugly)
× Defective (stained by visual external stains, and even when confirmed with a finger, there is a great sense of sliminess, and the sound is also ugly and ugly)

Next, we will discuss the experimental results in detail.
As a result of testing elastic bodies of different hardness and material in making the present invention, a cylindrical object having a hardness of about 50 to 60 with a protrusion was the easiest and most effective.
As for the size of the tip (2), a cylindrical shape with a diameter of about 12 mm was the easiest to use, and when it was 5 mm or 20 mm in diameter, the compatibility with the denture (9) was poor. 9) There are few surfaces to contact with, and it took time to clean.

By attaching the large protrusion (T1) and the small protrusion (T2), it was possible to clean the portion that did not reach on the smooth surface (M), so that the surface could be cleaned more cleanly.
When rubbing the denture (9), it was confirmed that a soft sponge-like material does not remove the dirt that is difficult to rub, and a hard material will damage the denture (9).

About Example 1, since there was moderate adhesion, the degree of rubbing was also very good and the degree of removal of dirt was also very good, and the workability and durability were also very good, so the cleaning time did not take and there was no stress ( 9) was cleaned.

About Example 2, since there was moderate adhesiveness, the rubbing condition was also very good and the dirt removal condition was also very good, and the durability was also very good. Although it was easy to get out, the workability was good and the cleaning time was not so much.

  In Example 3, the rubbing condition and durability were extremely good, but the degree of dirt removal was almost satisfactory. Also, workability and cleaning time were almost good.

  In Example 4, the rubbing condition was extremely good, but the degree of dirt removal was almost satisfactory. Workability, durability, and cleaning time were also almost good.

  As for Comparative Example 1, the durability was somewhat poor because it was too soft, the degree of rubbing and the removal of dirt were slightly poor, the workability was also poor, the cleaning time was long, and the result was slightly poor.

  In Comparative Example 2, the hardness was too hard and the rubbing condition was poor and the dropping condition was slightly poor. The workability was also hard, so the steps and gaps were not rubbed well and the cleaning time was slightly poor. However, the durability was good.

In the present invention, the dentures (9) can be polished quickly and reliably using an elastic body, so it is easy to check whether the dirt has been removed. Since it has a simple structure in which the tip (2) provided with a protrusion on the elastic body is composed of a grip (3) connected to the rear of the tip (2), it can be produced at low cost. Therefore, industrial applicability is great.
