E \ 4 In the toothbrush according to the invention, the handle provides a

5 containers for holding liquid or semi-liquid

6 toothpaste that is exchanged after the toothpaste is used up

7 and also elastic in at least one area

8 is.

\}> J 10 There is no doubt that the toothbrush according to the invention

11 ne considerable improvement on the conventional and currently on

12 toothbrushes available on the market, as they are for the

13 user is easy to handle, handle the toothpaste

14 and is easy to take with you as it has a cap

15 on which a clip for fastening inside the bag

16 of a piece of clothing or the like can be attached. 17th

18 Another decisive advantage of the invention

19 Toothbrushes are easy to manufacture, especially in the Hi η -

20 look at the purpose pursued with it. 21

22 The toothbrush according to the invention is preferably made of plastic

23 made of material, whereby the plastic of the container

24 can be seen in order to determine at a glance at any time

25 can see how much toothpaste is left in the container. 26th

U 27 According to the invention, the toothbrush consists of one

28 brush body with an internal passageway at one end

29 is connected to the bristles and at the other end to the

30 inside the handle that guides the container with the liquid

31 or semi-liquid toothpaste forms. 32

33 The brush body and handle are connected to the

34 side opposite the bristles; there is one

35 Tapering with a circumferential gradation, which is

36 bond between the brush body and the inside of the handle.

1 As soon as the brush body and handle are connected to one another,

2 is through the corresponding end area of the brush body

3 an inner wall on the handle or toothpaste container removed. 4th

5 This wall is removed because the brush body is attached

6 has a slope at the corresponding end, with which a

7 penetration area is defined; this makes the wall whole

8 or partially removed so that the end of the passage with

9 the inside of the container that holds the toothpaste

10 is connected.
11th

12 The free end of the handle is thinner and makes it easy

13 represents deformable area; when pressure is applied

14 the liquid or semi-liquid toothpaste becomes the passage

15 pressed inside the brush body and gets into the

16 corresponding area of the bristles.
17th

18 The end of the brush body that connected to the container

19 can be of various shapes; however, all of them are so

20 placed so that the inner wall can be easily removed. 21

22 Since the handle and thus the toothpaste container are easy to

23 is exchangeable, the removable wall of the container is used

24 as a closure until the connection with the brush body takes place,

25 because this exchange part will be sold individually by retailers

26 den. It must therefore be ensured that the liquid or semi-

27 liquid toothpaste in the container that will later hold the handle of the

28 represents toothbrush is hermetically sealed. 29

30 To make it easier to understand the structure and use of the

31 toothbrush will be a practical example below

32 of the toothbrush. This is only an example and can

33 should therefore not be a restriction in any way. Reference is made to the

34 attached drawing, wherein 35

36 Fig. 1 is a sectional view of the toothbrush formed from Figs

37 consists of two main parts, body and handle.

1 Fig. 2 shows in detail the shape of the end of the brush body,

2 over which the brush body inside with the handle

3 is connected. 4th

5 FIG. 3 shows a sectional view of an embodiment variant of FIG.

6 is. 7 8 Fig. 4 is a view of the toothbrush with the cap. 9

10 In Fig. 1, the toothbrush 1 consisting of handle 2 and

11 brush body 3 shown. 12th

13 The brush body 3 has a passage 4, one end of which

14 is connected to the bristle area, while the other end

15 is designed as an incline and part of the also inclined

16 end 7, in which a region 8 of the brush body ends, the

17 represents a circumferential step 9, which is used as a stop for the

18 end 10 of the handle is used. 19th

20 The handle 2 forms a container 11, in the interior of which

21 the liquid or semi-liquid toothpaste is located here

22 is not shown. 23

24 The container is closed by a wall 12 passing through the

25 bevel 7 at the end of the brush body when attaching

26 or partially removed. 27

28 In Fig. 2 the shape of the end 8 is shown; at the free end

29 there is a central recess 13, which expands

30 represents the transition of passage 4. 31

32 In Fig. 3 the aforementioned area 8 is shown, the

33 at its free end from a frustoconical area

34 14 consists, thus removing the wall 12 of the container

35 is facilitated.

1 The handle 2 also has a thinner end 15, which by pressure

2 can be easily deformed in order to transport the liquid

3 or semi-liquid toothpaste to the opposite end of the

4 to allow passage 4 of the brush body. 5

6 The toothbrush T finally shows a cap 16 with a

7 Clip 17 for fastening e.g. to the pocket of a clothing

8 pieces. With this cap, the brush body is

9 dirt protected. So that air can get to the bristles,

10 openings 18 are provided on the cap body. 11th

12 After this detailed description of the invention as well

13 of their practical execution, it should be pointed out

14 sen that the described arrangements changed in details

15 as long as the main features of it are not

16 be stirred.
