Description

TOOTH BRUSH

Technical Field

The invention is related to tooth brushes resolving their new constructional and functional conception.

Background Art

Mouth cleaning is one of the most frequent acts of personal hygiene. In spite of the fact that there are several different requisites for mouth cleaning, such as dental floss, rinsing equipment with concentrated stream of water or other liquids, the tooth brush has still retained its dominant position.

There are dozens of variations of concrete technical designs of the tooth brush which should make mouth cleaning more effective.

The aim of various tooth brush construction designs is to achieve perfect and quick tooth cleaning and also to ensure gum massage. It is important that it does not damage gum, mouth or teeth .

The principal construction designs, by means of which the aforementioned effects should be accomplished, are based mainly on the form and elasticity of handle, shape, material, location, length and thickness of bristles.

Tooth brushes with narrow and suitably shaped neck between handle and tooth brush head belong to designs with better effects. There are also designs in which the handle is in the neck area connected to the head by a joint (e.g. Japanese patent application No. 010 54641 ) .

There exists also a tooth brush design (the Japanese patent application No. 010 999 66 ) that has in the handle a longitudinal hole for tooth paste. This hole passes into the head of the tooth brush where it leads into the openings in places where bristles are fixed into the tooth brush head. Such a tooth brush ensures the necessary supply of tooth paste during the tooth cleaning as well.

Apart from the function of a usual handle or storage of paste, there are handle holes with space for batteries, a little engine, or other electric or electronic equipment ensuring movement of bristles or other effects on teeth, gum or other parts of mouth. The next category of tooth brushes consists of brushes with multiple heads.

This construction design contains the tooth brush, which is designed so that the handle passes to the neck, which is divided into two heads, placed next to each other. Bristles from both heads are orientated in the same direction. Regarding the elasticity of tooth head material, bristles can better adapt to the shape of teeth.

Brushes with multiple heads are designed in another way too. The essence is that the tooth brush has two heads, placed next to each other, in which bristles are placed so that they are orientated mutually opposite. Such a tooth brush enables to clean both outside and inside surface of teeth simultaneously.

The invention of the cleaning brush according to the invention registration of the Slovak Republic No. 77 - 94 is of similar design. The cleaning tooth brush consists of a handle and longitudinal rows of cleaning bristles which are orientated in the direction of the tooth brush longitudinal axis. The handle has longitudinal grooves, depth of which is usually equal to thickness of the handle and the length is bigger than the length of the longitudinal rows of cleaning bristles. The stiffness of diffraction of individual parts of the handle divided by the longitudinal grooves is not constant and is smaller than stiffness of diffraction of the other parts of the handle.

The construction design according to the Japanese invention registration No. 020 889 16 is also very interesting; basically, it is a connection of two tooth brushes, placed next to each other and connected. The connection is gained by means of elastic coupling , fixed in the tooth brush handles. Thanks to elasticity of used materials, such a connection ensures better adaptation of position of tooth brush heads to the shape of teeth. This tooth brush enables cleaning of both upper and lower teeth.

There is also a tooth brush, with the head orientated vertically at handle .

Another invention of tooth brush (Japanese patent application No. 020 897 46 ), essence of which is that there are bristles fixed in the block of head so that they protrude on both sides of the head. Bristles on one side of head can be different to those on the other head and in material, length or thickness.

There exist also tooth brushes produced from one piece of elastic material. Their essence is such, that there are openings in the tooth brush head for inserting the finger and bristles produced from the same material as the body of the tooth brush, protrude from the outside surface of tooth brush. Such tooth brushes have an advantage especially in the higher sensitiveness in cleaning teeth and by their untraditional construction design, they are more attractive for children.

In spite of the amount of tooth brush inventions, the problem of perfect mouth cleaning remains unresolved. Each of the chosen typical representatives of the tooth brush construction design has also disadvantages.

Main disadvantages include production demands, complexity of usage as well as limited ability to sufficiently remove remaining pieces of food while simultaneously polishing tooth enamel.

Disclosure of the Invention

The above mentioned disadvantages are to great extent removed by the following tooth brush construction design invention.

Its essence is such, that the tooth brush constructed from a handle, at least one neck and at least on head with bristles has at least one polishing block connected to the head.

The polishing block can be from an elastic material containing abrasive particles.

Surface of the polishing block can be shaped for example into wave-like or other shape.

The polishing block can also contain antibacterial substances.

The polishing block from physically not harmful, edible and gradually soluble material could be advantageous.

The polishing block can consist of several parts with various material characteristics.

The tooth brush according to this invention can be also constructed so, that the polishing block is connected to the reverse side of the head, which block is suitable for mouth massage or is soluble and contains antibacterial substances.

Main advantages of the tooth brush according to this invention include the improved ability of perfect mouth cleaning a simultaneously better polishing of tooth enamel. Another possibility is the antibacterial effect even without tooth paste. Brief Description of Drawings

Actual tooth brush construction designs according to this invention are shown on attached figures.

Fig. 1 shows basic construction design of the tooth brush with the polishing block.

Fig. 2 shows the tooth brush with the polishing block with abrasive particles, surface of which is undulated.

Fig. 3 shows the tooth brush according to this invention with the polishing block on the reverse side of the head.

Best Mode for Carrying Out the Invention

Example 1

The tooth brush consists of handle 1, neck 2 and head 3 with bristles 4, with the polishing block 5 connected to the head 3 so, that bristles 4 go through it.

Example 2

The tooth brush consists of handle 1, one neck 2 and one head 3 with bristles 4 with the polishing block 5 connected to the head 3. The polishing block 5 of this construction design is from an elastic material that contains abrasive particles.

Surface of the polishing block 5 is undulated.

Example 3

The tooth brush consists of handle 1, neck 2 and head 3 with bristles 4, with the polishing block 5 connected to the head 3 so that bristles go through it.

Another polishing block 5 is connected to the reverse side of the head 3. This polishing block 5 contains physically not harmful, edible and gradually soluble material also containing antibacterial substances.

Industrial Applicability

The invention is utilisable mainly in manufacture of tooth brushes with improved cleaning and polishing effects.
