Definitions
- the invention relates to a toothbrush with a toothbrush neck and a toothbrush handle having a toothbrush handle according to the preamble of claim 1.
- Such a toothbrush is known from DE 36 40 898 C1, where the brush head with an elastic connecting part a toothbrush handle is connected, wherein the elastic connecting part is designed so flexible that the brush head compared to the Toothbrush handle in a horizontal plane with respect to the bristle bed evades.
- the elastic connecting part forms a toothbrush neck, that can avoid a rigid toothbrush handle.
- the Evasion takes place compared to the toothbrush handle, whereby elastic connecting part forms a long swivel arm.
- the integration such an elastic connecting part is not only strong shape-determining for the toothbrush and expensive, but also hinders an even cleaning of the teeth.
- WO 92/15198 A1 describes articles for oral care, such as, for example Toothbrushes and toothpicks, known from a polymer material exist and with a chemically or biologically active substance are coated.
- Cellulose esters include in particular cellulose acetopropionate.
- Such polymer materials ensure that the coating substance in one aqueous medium does not come off. Gum injuries are tried here through antibacterial or antimicrobial coatings on the toothbrush to avoid. With such toothbrushes it is not achieved that the toothbrush head dodges under stress.
- the object of the invention is therefore a toothbrush according to the preamble of claim 1 to create, which is simple and a springs of the brush head while maintaining good leadership of the Toothbrush allowed.
- the brush head can swing with every cleaning movement and optimally handle the hand pressure and adjust the jaw conditions. So that are violations of the sensitive gums almost impossible.
- the elastic deformability of the toothbrush neck can thus be optimized be that this together with its subsection more constant Width has a round or elliptical cross section.
- toothbrush handle made from a cellulose propionate or cellulose acetopropionate to create a continuous transition between the toothbrush neck and toothbrush handle of the toothbrush handle is ensured.
- the toothbrush handle can be flat elliptical, whereby the handling of the toothbrush is simplified.
- the elastic toothbrush neck can also be used as an attachment for an electric toothbrush Find use.
- the invention relates to a toothbrush 1 with a toothbrush handle 2, which comprises a toothbrush handle 3 and a toothbrush neck 4.
- a toothbrush handle 2 which comprises a toothbrush handle 3 and a toothbrush neck 4.
- a brush head 5 which is preferably is integrally connected to the toothbrush neck 4.
- the toothbrush neck 4 is of a narrow or very thin-rod section from a cellulose ester, in particular from a cellulose propionate or cellulose acetopropionate.
- the rod section points a constant at least along a partial longitudinal section 6 Width 8, in particular a constant cross section.
- the toothbrush neck 4 is consequently held in fine-grained form with a width 8, which is preferably is in the range between 3 and 6 mm.
- the width is 8 less than half a width of the toothbrush handle 3 on it strongest place.
- the necessary toothbrush neck 4 itself thus forms a spring element.
- the length of the section 6 with a constant cross section is 1 to 3 cm.
- the length of the toothbrush neck 4 is chosen such that this at least 15%, especially 20 to 30%, of the length of the toothbrush handle 2 matters.
- the choice of material and design creates a uniform one Component created in which a small or short section of Toothbrush handle 2 dodges defined, so that the swinging motion the brush head is limited.
- the toothbrush handle 2 is preferably straight, wherein the narrowest-toothed toothbrush neck 4 with a slight angle ⁇ from 1 ° to 5 °, in particular 2 ° to 3 °, relative to the toothbrush handle 3 can be angled.
- the front of the brush head 5 and the toothbrush handle 4 then form an obtuse angle.
- the entire toothbrush handle 2 consists of one Cellulose esters, such as in particular a cellulose propionate or a Cellulose acetopropionate.
- the toothbrush handle 2 preferably comprises one Toothbrush handle 3 with a flat elliptical cross section.
- the brush head 5 is in a known manner with bristles 7 on the front.
- the toothbrush handle 2 can continue, apart from recessed grips and / or a front thumb support 9, a continuous, even Have thickness.
- the toothbrush body of the electric toothbrush serves as a drive device in addition to its function as a toothbrush handle for a rotating and / or oscillating-rotating movement of the brush head.
