 The wall of the container part 2a is preferably made elastic, at least partially elastic, so that the user of the treatment liquid can force the treatment liquid to enter the treatment head 3 through the treatment liquid channel and thereby squeeze out the treatment liquid discharge port , wherein the above-mentioned treatment liquid channel is formed by the short outlet tube 26 and the hollow rod 28 of the treatment part 2b in a state where the two parts are screwed together.
 The container part 2a and the treatment part 2b can be put into a compact unit without being screwed together, that is, especially during the period between manufacture and use of the oral hygiene implement of the present invention, because the treatment The shape and length of the rod 28 of the part 2b are selected such that the treatment part 2b in the assembled state at least substantially fills the groove-shaped recess 25 of the container part 2a, while the rod 28 is away from the rear side of the bristles 4 and adjacent on both sides. The outer surface area of the groove-shaped recess 25 is almost flush. Thus, the bristles 4 are located close to the outlet stub 26 .
In addition, there is provided a cover 23 whose cross section is substantially the same as that of the container portion 2a when the processing portion 2b is housed in the recess 25. As shown in FIG. The cover 23 can be mounted on the side or end of the combined part 2a, 2b with the outlet stub 26 and the bristles 4 in a preferably latching manner. The wall of the cover 23 is interrupted by a cut-out 25 ′ having an approximately U-shaped profile which, when the cover 23 is in place, adjoins the groove-shaped recess 25 and serves to receive the part of the rod 28 not located in the recess 25 .
 A protrusion (cannot be seen in the figure) is preferably set in the inside of cover 23, and it is especially made in the form of a kind of closure plug and preferably forms an integral body with the end face of cover 23, simultaneously, when cover 23 When in place, the protrusion closes the treatment liquid outlet 24 in a liquid tight manner. Therefore, leakage of the treatment liquid can be reliably prevented in any orientation of the oral hygiene implement 1 when not in use.
 As shown in the figure, in the fully assembled state of the embodiment of the oral hygiene implement 1 according to the present invention, the bristles 4 and the short outlet tube 26 are all protected inside the cover 23, so in a hygienic way See justifiable ways and institutions protected from outside influence. In addition, since the parts of the oral hygiene implement 1 according to the invention have the described shape, the whole formed by them is very portable, takes up little space, and does not have any interfering protrusions on the outer surface of the whole, And it will not cause any problems during transportation and storage.
 In the assembled state, the treatment liquid inlet 29 of the rod 28 can be closed by a cover plate (not shown in the figure), which is formed in the container opposite to the outlet stub 26, so that it can likewise be protected from external influences. In the bottom region of the part 2a, it is approximately parallel to the bottom of the container part 2a, and is preferably integral with the latter.
 The cover 23, especially the edge of the U-shaped cutout area 25', and the treatment head 3, especially the edge area of its side facing the bristles 4, are provided with clamping mechanisms 30, 31, which are assembled together. This ensures that the processing part 2b will not be lost in the combined state.
 According to the illustrated embodiment, the longitudinal rib 31 is used as a holding mechanism for the treatment part 2b, while the longitudinal rib on the cover 23 is formed as a groove-shaped longitudinal recess 30 into which the longitudinal rib 31 is slidably introduced so that the cover 23 in place.
 When the cover 23 is initially in position, the treatment part 2 b together with the longitudinal rib can then be latchingly engaged into the longitudinal rib 30 and the rod 28 enters the groove-shaped recess 25 .
 The edge region of the U-shaped cutout 25' can also simply serve as a fastening means 30 for the cover 23, and the longitudinal rib 31 of the treatment part 2b fits fixedly behind the edge region of the U-shaped cutout in the assembled state.
 Alternatively, it is also possible to omit the clamping means 30, 31 and to dimension the rod so that it can be inserted clampingly into the groove-like recess 25 and thus also secured against loss.
 At least the elastic region of the container part 2a is preferably made of soft plastic, for example a soft polyvinyl compound. Furthermore, all individual parts of the oral hygiene implement 1 of the present invention, including the treatment part 2b integrally formed with the bristles 4, are preferably manufactured by injection molding.
 It is preferable to use recyclable materials, at least most of the parts are made of recyclable materials, so that the oral hygiene appliance 1 of the present invention is easy to meet the requirements of environmental protection.
 Storage and/or display of the oral hygiene implement 1 according to the invention is preferably in transparent plastic packaging. The at least partially light-permeable design of the container part 2a in combination with the use of colored treatment fluids ensures the positive effects already mentioned above.
 The packaging of the oral hygiene implements according to the invention is preferably closed in an airtight manner in order to ensure that their storage is problem-free from a hygienic point of view.
 When using the oral hygiene implement 1 of the present invention, after removing its outer package, it is necessary to first remove the cover 23, and then screw the treatment part 2b onto the container part 2a. By pressurizing the elastic region of the container part 2a, the treatment liquid contained in the cavity flows to the treatment head 3 and thus can be used mechanically by means of the bristles 4 for the treatment of the oral cavity, in particular to help clean the teeth.
 The bottom area of the container part 2a opposite the outlet stub 26 can be made in such a way that the cap 3 can be locked on this area. In this way, on the one hand the container part 2a and thus the handle 2 are lengthened, and on the other hand the cover 23 is prevented from being accidentally lost.
 The oral hygiene implement 1 according to the present invention enables a very simple yet effective oral cleaning without the need for additional treatment implements or water, while achieving a significantly improved oral hygiene while at the same time making the user feel Pleasant and fresh double effect.
