Definitions

  • the invention relates to a brush, in particular a disposable toothbrush, according to the independent device claim, comprising a brush head, in which a channel is formed, a handle, in which a cavity is formed, wherein the cavity is connected to the channel, a piston, the in the cavity is movably receivable, and a cartridge for receiving at least a first means, which is arranged in the cavity, is formed. Furthermore, the invention relates to a method for actuating a brush, in particular a disposable brush, according to the independent method claim.
  • a toothbrush which is designed as a disposable brush.
  • the brush comprises a brush head, in which a channel is formed, a handle, in which a cavity is formed, wherein the cavity is connected to the channel, a piston which is movably received in the cavity, and a cartridge for receiving at least one first means, which can be arranged in the cavity.
  • the piston is movable between two positions in the cavity, namely a rest position in which the piston rests against the cartridge, and an actuating position in which the piston is inserted into the cartridge. It has been found difficult to arrange the cartridge just in the cavity. Thus, the assembly of the brush is difficult.
  • the disclosed brush can therefore operate cumbersome. It is therefore an object of the present invention to improve a brush (in particular toothbrush) of the aforementioned type. In particular, it is an object of the present invention to improve the functionality of the brush. It is another object of the invention to facilitate the assembly of the brush. It is another object of the invention to allow a simple arrangement and improved positioning of the cartridge in the cavity. In addition, it is an object of the invention to improve the operation of the brush or the piston, in particular to facilitate.
  • the invention includes the technical teaching to move the piston between at least two positions in the cavity, namely a rest position in which the piston with the cartridge, in particular detachably, is connectable to arrange the cartridge in the cavity, and an actuating position, in which the piston is at least partially insertable into the cartridge to empty the contents of the cartridge through the channel, the piston being adapted to make a, in particular detachable, connection to the cartridge.
  • the term brush is understood in particular to mean a (purely mechanical) toothbrush and / or a disposable toothbrush.
  • the present inventive concept is to facilitate and improve the placement and positioning of the cartridge in the cavity by temporarily attaching the cartridge to the piston, for example at one end of the piston axially of the piston.
  • This may allow a user to conveniently grasp a free end of the piston for insertion of the cartridge into the cavity, with the cartridge axially secured to the piston at the other end. While the user can simply hold the free end of the piston, he can in a same sequence of movements, the cartridge together with the handle purposefully introduce into the cavity. Thus, the assembly of the brush can be facilitated. Also, it can thus be ensured that the cartridge is being placed in the cavity. Thereafter, the temporary attachment of the cartridge can be solved on the piston.
  • Proper positioning of the cartridge in the cavity may further ensure that the piston can be securely aligned axially with the cartridge for engagement with the cartridge, and that the piston can engage accurately and cleanly with an end face of the cartridge. This prevents the cartridge from being able to be opened laterally and allowing the contents of the cartridge to leak out of the cartridge at the sides. Rather, this makes it possible that the contents of the cartridge is purposefully transported into the channel.
  • the assembly of the brush and the operation of the brush or the piston thereby become simple, safe and pleasant.
  • the brush head can have an exchangeable functional body with bristles.
  • the brush head and the handle can be formed as a monolithic and / or unitary material body of only one material, for example. Plastic.

  • a positive and / or non-positive connection can be produced easily and with simple means.
  • the attachment of the functional body can be facilitated on the brush head, whereby the manufacture and assembly of the brush can also be simplified.
  • the functional body can have at least one latching element, in particular in the form of a latching lug, which can be introduced into the channel through a fastening opening in the brush head and latched in the channel.
  • the attachment opening may be formed in the brush head perpendicular to the channel.
  • the latching element can thus extend through the attachment opening and engage with the latching lug in the channel.
  • a secure positive and / or non-positive connection between the functional body and the brush head can be produced.
  • Such a locking element is also easy to manufacture, for example.
  • a channel in the brush head is designed to deliver the agent from the cartridge and does not require additional modification to cooperate with the detent.
  • the channel can be formed continuously to reach from the cavity to the outside of the brush head.
  • Such a channel is easy to introduce from the outside into the brush head by a flat sliding knife. Consequently, only one locking element on the functional body must be formed, which can cooperate with the functional channel in the brush head to produce a secure attachment of the functional body with the brush head.
  • Locking element bring the advantage that it can also perform a closing function in addition to a fastening function.
  • the locking element can close the channel to the outside to prevent accidental leakage of the agent from the brush head, except at the intended outlet openings from the channel, which extend between the bristles on the functional body.
  • the functional body can have at least one blocking rib, in particular in the form of a bolt or web, which can be introduced into the channel through a fastening opening in the brush head and which can close the channel to the outside.
  • the blocking rib may be formed next to the locking element on the functional body and be introduced through the same or through a separate attachment opening in the brush head in the channel.
  • the blocking rib can thereby reliably prevent the agent from the cartridge can leak out of the brush head except at the intended outlet openings.
  • the cartridge may for this purpose be constructed of flexible material which is somewhat expansible when the piston is inserted into the cartridge.
  • a separate blocking rib adjacent to the detent element can bring about the advantage that the blocking rib can close off the outermost outlet opening for the means in the brush head towards the channel, in order to allow complete depletion of the agent through the outlet openings.
  • the brush head may have a first functional body with bristles, for example for a tooth cleaning, and a second functional body with grooves, for example for a tongue cleaning, wherein in particular the first functional body can be arranged on an upper side and wherein second functional body may be formed on an underside of the brush head.

  • the outlet openings thus ensure that the agent from the cartridge, for example.
  • a toothpaste In the form of a toothpaste, through the channel and through the outlet openings can get up to the bristles on the functional body.
  • the brush is advantageously ready to work immediately. The user only has to push on the plunger to force the toothpaste out of the cartridge.
  • the outlet openings may also have different diameters, in particular, the outlet openings may have a decreasing or reduced diameter in the direction of the cavity. With the distance from the cavity, the pressure decreases, with which the agent can be pushed out through the channel.
  • the outlet openings with the increasing diameter with the distance from the cavity advantageously provide for a uniform flow of the agent from all the outlet openings.

  • This can be advantageous on the one hand to even out the exit of the agent from the outlet openings.
  • the outlet of the agent can be portioned out of the outlet openings. This can be particularly advantageous when the brush is used several times, so that the agent between the uses can not dry out. Portioning of the agent can also be advantageous if the cartridge comprises different means to deliver the different agents portioned in succession, such. First, water to moisten the teeth, then toothpaste to clean the teeth and then mouthwash to rinse the oral cavity.
