Description

  The present invention relates to the field of dental care, and more particularly to a tooth cleaning device that can be placed in the mouth and changed in position without being held by a user's hand.

  In recent years, attention has been focused on techniques that leave teeth, jawbone structures, and gums in good condition, if possible, until the age of the individual, as long as the life of the individual lasts. In particular, since dental health is highly dependent on dental care, it is strongly recommended that teeth be cleaned after every meal, if possible.

  However, the most common dental care technologies and equipment, such as hand-held toothbrushes and toothpastes, require water supply and a basin or basin, so water and / or a suitable structure In any situation where it is not immediately free, tooth cleaning is not available.

  Nowadays, it is increasingly common to have a few meals quickly, spending most of the day outside the home, working, traveling (eg, on the plane), or similar business and / or leisure activities It ’s becoming a reality.

  In all these situations and other day-to-day situations, it is highly desirable and beneficial to have the opportunity to utilize dental cleaning not only for health reasons but also to refresh the breath.

  However, due to time constraints and other day-to-day circumstances, it is very often the case that the effort required to keep the teeth sufficiently clean is stopped.

  In addition, it is necessary to use both hands to apply toothpaste to a conventional toothbrush, which is almost insignificant for people with restricted upper body movements or those who do not function, i.e. those who are not half-body. It is possible.

  Moreover, in recent years, there has been an increased interest in the problems and / or predicaments of disabled people (eg, wheelchair users), but many public toilets and / or toilets are still difficult for disabled people to use. For example, even if it is available, it is often not possible for a disabled person to use dental cleaning in public toilets because it is not fully equipped.

  In order to eliminate these disadvantages, numerous solutions have been proposed in the industry with the goal of making dental cleaning available in all day-to-day situations.

  For example, it has been proposed to use chewing gum as an aid to clean teeth, which is advantageous in that it does not require a water supply and a wash basin, but chewing gum has a series of teeth, in particular, The area where the teeth and gum are in close contact may not be cleaned to a very good extent.

  Several types of handless brushes and brush balls have also been proposed. These devices are inserted into the mouth to chew and clean the surface of the teeth with elongating hair. One of these devices is disclosed in UK Patent Application No. 2351015, published on December 20, 2000. The device, in the main embodiment with short hairs extending outward, has a foldable hollow spherical ball with elasticity so that the user can clean the teeth while the ball is cleaning. The ball can be chewed, and the hollow ball is perforated and includes toothpaste that is dispersed as the ball is chewed.

  While this may be practical to some extent, it has been found that the cleaning results obtained with this type of chewing ball are in most cases not satisfactory. This is especially due to the fact that when chewing the ball, only the tooth mating surfaces are cleaned and the food particles between the teeth are not removed. Further, the ball is bitten at a predetermined position between the teeth according to the method that the user is used to biting. Since the ball does not move in any position in the mouth, there remain some places where the ball is not subjected to the cleaning action.

  In view of the foregoing, it would be highly desirable to provide an improved tooth cleaning device that eliminates or partially limits the disadvantages of the prior art.

  In general, the present invention relates to a handless cleaning device that can be easily moved to any position in the mouth, thereby providing excellent cleaning results.
