Description

  The present invention relates to an oral cleaning tool in which a cleaning part is attached to an end of a grip part.

  In recent years, oral cleaners with a cleaning part such as resin foam or brush attached to the end of the gripping part are widely used for hospitals and homes for cleaning the oral cavity of elderly people, sick people, etc. who need nursing care Being started.

  As for the oral cleaner, various materials have been proposed for the cleaning portion at the tip, but the grip portion is generally a rod-shaped body made of plastic such as polypropylene or ABS, or a paper roll (cylindrical) material. is there.

  However, although the plastic gripping part is relatively strong, the surface of the gripping part is smooth, so in nursing care etc., the hand holding the gripping part is slippery due to the wetness of the gripping part due to dripping of saliva, etc. There are problems such as inferior. In addition, the plastic gripping portion lacks elasticity, and is easily broken and difficult to handle when a certain degree of strength is applied. Furthermore, the cleaning part is often fixed to the gripping part by bonding, but the resin foam constituting the cleaning part and the plastic constituting the gripping part are inferior in adhesiveness. There is also a risk that parts will fall off. For example, olefin-based plastics such as polypropylene that are frequently used as gripping parts have low adhesive strength.

  On the other hand, if the gripping part of the paper-based roll material is immersed in warm water or left in a state where saliva is attached, the strength will be significantly reduced, and the durability will be inferior to that of the plastic gripping part. is there.

  In the oral cleaner 10A of FIG. 1, the material of the gripping part 11A is bamboo, the shape of the gripping part 11A is a round bar having a diameter of 4 mm and a total length of 140 mm, while the material of the cleaning part 11A is polyurethane foam, the cleaning part The shape of 11A was a cylindrical body having a diameter of 20 mm and a length of 23 mm, and the oral cavity cleaning device of Example 1 was formed by inserting 15 mm of the distal end side of the gripping portion 11A into the cleaning portion 21A and fixing it with an adhesive. Moreover, the said oral cavity cleaning tool of Example 2 was created as a tree (cypress) instead of the said holding | gripping part 11A.

  On the other hand, the oral cleaning tool of Comparative Example 1 in which the gripping part 11A is ABS resin, the oral cleaning tool of Comparative Example 2 in which the gripping part 11A is polypropylene (PP), and the Comparative Example 3 in which the gripping part 11A is a paper roll. An oral cleaner was created.

The use durability, shape retention, and feeling of use were evaluated for the oral cleaners of each Example and Comparative Example.
For durability and shape retention, the following strength tests were conducted after drying, after immersion at room temperature, and after immersion in warm water.
In the strength test during drying, 20 ° C., 50% R.D. H. In this state, the oral cleaner left for 24 hours or more was taken out, and the strength of the gripping part was measured. The tip of the cleaning part was fixed, the gripping part was held at an angle of about 45 degrees, and a load of 1.5 kg or more was suspended at a site 50 mm from the tip. ○ that does not break at a load of 1.5 kg or more and returns to its original state after removing the load, △ that cannot be folded at a load of 1.5 kg or more, but that has been confirmed to be deformed after the load is removed △ Those broken within 1.5 kg were marked with x. In the strength test at the time of drying, several of the 20 paper rolls were deformed after the load was removed.

In the room temperature immersion test, the oral cleaner was immersed in pure water at room temperature from the cleaning part to 70 mm for about 30 minutes. Thereafter, the strength test at the time of drying and a corresponding evaluation were performed without wiping off water. In this normal temperature immersion test, the strength of the paper roll was significantly reduced, and it broke and deformed at about 1.0 kg, and recovery after deformation could not be confirmed. Moreover, the folding was confirmed by applying a load several times.
In the warm water immersion test, the oral cleaner was immersed in warm water at 40 ° C. for about 30 minutes from the cleaning part to 70 mm. Thereafter, the strength test at the time of drying and a corresponding evaluation were performed without wiping off water. In this hot water immersion test, the strength reduction of the paper roll was confirmed more remarkably than that at room temperature immersion, and when the gripping portion was rubbed, a crack occurred. It was confirmed that the resin had a lower strength than polypropylene (PP) having a low heat resistance temperature.

The feeling of use was evaluated with respect to dripping, spring feeling and grip.
The liquid dripping property was measured by measuring the distance that pure water travels through the gripping part by dropping 1 cc of pure water from above into the gripping part directly below the cleaning part. The inclination angle of the gripping part was 45 degrees. Evaluation was made as to whether or not the pure water transmitted through the gripping part reaches the end of the gripping part. When the pure water was transmitted to the tip of the gripping part, it was marked as x, and when it stopped halfway, it was marked as ◯.
In the plant-based gripping part and the paper-based gripping part, since the gripping part easily holds and absorbs liquid such as saliva, the liquid dripping is low and it is difficult to transmit to the tip of the gripping part. On the other hand, since the gripping portion made of synthetic resin is smooth and has no liquid retaining property, it was confirmed that liquid dripping was relatively remarkable.

  The feeling of spring is judged by the sensory test of the feeling of use due to the deflection of the gripping part during actual use, ○ if there is deflection and recovery after displacement is confirmed, △ if it is difficult to feel the deflection itself, and there is deflection The case where the recoverability after displacement was inferior was evaluated as x.

  The grip property was judged by a sensory test to feel the gripping part in actual use. Even if the gripping part is wet or wet with liquid etc., there is no noticeable difference in grip and workability. △ was designated as △. Since the surface of the synthetic resin product was smooth, when the grip portion was wet, it was confirmed that the grip was relatively inferior. There was no difference in grip between the plant-based and paper-based gripping parts because the gripping parts were wet, and that they were easy to hold. However, in the paper-based gripping part, it was confirmed that the chipping was generated when the grip was wet and the grip was rubbed. In the case of the bamboo of the present invention, since the fiber streaks are in the longitudinal direction and grooves in the longitudinal direction of the surface are formed, particularly excellent workability has been confirmed for grip properties such as ease of gripping and ease of gripping. The evaluation results are shown in Table 1.

  As shown in Table 1, with respect to Example 1 in which the gripping portion is made of bamboo, use durability, shape retention, and feeling of use were all good. Further, in Example 2 in which the gripping portion is made of wood, all were good except that the evaluation was Δ only by the spring feeling in use feeling.

  On the other hand, in Comparative Example 1 in which the gripping part is made of ABS resin, saliva is easily transmitted to the gripping part, and the fit feeling when gripping the gripping part is inferior. there were. Further, Comparative Example 2 in which the gripping portion is made of propylene is also easy to transmit saliva to the gripping portion and inferior to the fit when gripping the gripping portion, so that the liquid sagging property and gripping property in use feeling are Δ, In the retention hot water immersion test, Δ was obtained. On the other hand, in Comparative Example 3 in which the gripping part is a paper roll, the paper part swells after the gripping part is immersed in water, resulting in a decrease in strength, and the flexibility of the gripping part during use is inferior. Except for the sagging property, it was Δ or ×.

  As described above, the oral cleaning device of the present invention has a gripping portion that has strength, durability, and appropriate elasticity, and is difficult to slip even when moisture such as saliva adheres to the gripping portion. Even if it is immersed in warm water or when it is left in a state where saliva is attached to the gripping part, the strength is hardly lowered, and the adhesive strength between the cleaning part and the gripping part is high, and the cleaning part is difficult to drop off from the gripping part. .
