Definitions

  • the invention relates to a toothbrush according to the preamble of claim 1.
  • This toothbrush is hardly suitable as a travel toothbrush because the dosing screw protrudes far beyond the toothbrush housing and can easily break off.
  • the dosing screw doubles the length of the toothbrush.
  • the crushing roller provided there is hindered in its rolling movement, because on the one hand it should roll on the toothpaste tube and on the other hand it abuts the housing on the opposite side.
  • a shorter travel toothbrush is known from DE OS 43 01 720.
  • Such travel toothbrush offers the advantage of an integrated design with the inclusion of a required amount of toothpaste in the handle for dental care on the go at all times.
  • Toothbrushes of this type can only be taken along, especially at the holiday location, if they are not only correspondingly small, but also correspondingly light.
  • toothbrushes are known from US Pat. No. 3,734,118 or US Pat. No. 5,382,107 or DE GM 7118432, in which the handle is connected to the brush part via a swivel joint.
  • these toothbrushes have the disadvantage of inaccurate dosing and the deposition of toothpaste in the toothpaste container.
  • the advantage of the invention is that there is only a small space requirement for the transport of the toothbrush. This advantage is achieved by the possibility of bringing the handle and handle into a short end position as soon as the toothbrush is not used.
  • the handle either disappears completely in the handle or the handle is arranged along the handle and fastened there. In this way, the transport length of the toothbrush can be practically halved.
  • a toothbrush is therefore significantly less bulky than previously known designs.
  • Such a toothbrush fits easily into a jacket pocket, for example. To use such a toothbrush, it is only necessary to reposition / fold down the handle with respect to the handle into the long end position, and the toothbrush is ready for use.
  • the combination of these features in connection with a toothpaste container and dosing device integrated in the handle is particularly important because it has been shown that the handle has an ergonomically extremely favorable length / thickness ratio receives.
  • the handle thus offers a secure grip for the user, thus ensuring good and exact guidance of the brush head with a relaxed hand position at the same time.
  • An essential aspect of the invention is the arrangement of the brush head in front of the toothpaste outlet opening when the handle and handle are fixed in a short end position.
  • the minimum required total length of the toothbrush according to this invention is hardly more than a hand's width, possibly plus the length of the brush head.
  • the handle and the handle can either be translationally movable relative to one another or pivotable about a common swivel joint.
  • the handle and handle can be formed from two independent components.
  • the brush head lies in front of the toothpaste outlet opening, for hygienic removal of toothpaste for use.
  • Arranging the handle and handle so that they can be pivoted relative to one another about a common swivel joint offers the advantage of being secure against loss. If necessary, the swivel joint can be a detachable connection in order to be able to replace the handle and brush head if necessary.
  • the figures show a toothbrush 1 with a hollow handle 2.
  • the cavity 3 of the handle serves to hold a toothpaste container 4, consisting of a tube-like body extending in the longitudinal direction of the handle.
  • the toothpaste container 4 is emptied by means of the metering device 5 in that the metering device 5 can be rolled along the handle 2 over the tube-like toothpaste container 4. A volume of toothpaste corresponding to the feed of the metering device is squeezed out of the toothpaste container 4 and emptied via a toothpaste outlet opening 6 to the bristles 8 located on the brush head 7.
  • the brush head together with the handle 9 and the handle 2 are formed from two mutually independent components.
  • the handle 9 separate from the handle 2 is coupled to the handle 2 via a swivel joint 10. This will be discussed later.
  • handle 2 and handle 9 can be brought relative to one another into a long end position (see FIG. 4b) and into a short end position (see FIG. 4c).
  • the handle 2 with the extended handle 9 forms an essentially continuous straight connection.
  • the total length of this toothbrush in the long end position is about twice the handle length.
  • the handle 2 is fixed relative to the handle 9 in the long end position in such a way that it is not possible to stretch the structure shown beyond the 180 degree position. This is done by an associated pair of stops 11 between the handle 2 and handle 9, the consist of two material accumulations touching each other. If necessary, a clip connection 12 which fixes the long end position can additionally be provided between the handle 9 and the handle 2.
  • the toothpaste outlet opening 6 is formed by a nozzle 13 arranged at the end of the handle.
  • the nozzle 13 is firmly connected to the handle 2. It is a tubular nozzle which is connected to the toothpaste container 4 in the direction of the interior of the handle.
  • the tube cross-section can, as shown, be rectangular, advantageously also round, in particular circular, in order to avoid deposits of toothpaste in dead water zones.
  • the brush head 7 projects beyond the nozzle-side end of the handle 2, so that the brush head 7 or its bristles 8 come to rest below the toothpaste outlet opening 6. This allows the toothpaste to be completely expelled from the toothpaste container because no empty space arises.
  • the height H of the handle 2 is greater than the height h of the brush head by at least the thickness D of the nozzle.
  • FIGS. 2a-c show advantageous developments for a detachable interchangeable connection 14 between handle 2 and toothpaste container 4.
  • Figure 2a shows that the toothpaste container 4 can be connected together with a clip-in mouthpiece 15.
  • the mouthpiece 15 has slide-in strips 16 which engage in corresponding undercuts 17 in the handle 2. In this way, the mouthpiece 15 is firmly fixed in the handle 2 and can nevertheless be movable in the longitudinal direction of the insert strips 16 / undercuts 17 in order to be exchanged.
  • Figure 2b shows an alternative.
  • the toothpaste container 4 is provided with an extension plate 18 at its head end.
  • the extension plate 18 engages behind corresponding L-shaped grooves in the mouthpiece 15, so that the toothpaste container 4 is fixedly attached to the mouthpiece 15.
  • the provided outlet opening 20 for the toothpaste is closed in a suitable manner with a cover film, which cover film can be easily pierced.
  • FIG. 2c shows an orifice piece 15 likewise provided with insertion strips 16.
  • the orifice piece 15 here has a passage opening 21 through which the nozzle 13 can be inserted. In this case, however, the nozzle 13 is firmly connected to the toothpaste container 4.
  • FIGS. 2a-c also show that the toothpaste container 4 has a constricted end 22 in the rear region.
  • the constricted end 22 reduces the width B of the toothpaste container 4 to such an extent that the metering device 5 can lie practically without pressure on the rear end of the toothpaste container 4 after the toothpaste container 4 has been inserted into the handle 2.
  • the metering device 5 rests on the rear end of the toothpaste container 4.
  • the internal pressure of the toothpaste container 4 exerts a pressing force on the metering device 5, which tries to hold the metering device 5 against the squeezing direction.
  • the metering device 5 is designed as a knurled shaft 5 movable within the handle 2.
  • the knurled shaft 5 is guided at the end in longitudinal racks 23 on the handle 2.
  • the knurled shaft 5 has an end toothing 24 which is guided in a positive manner in the toothed racks 23.
  • the knurled shaft 5 is consequently guided in a form-fitting manner within the toothed rack 23, while at the same time a rolling movement of the outer contour of the knurled shaft 5 (see handle 25) on the facing top of the toothpaste container 4 takes place.
  • FIG. 1 shows that the handle 2 is supplemented by a closure cap 27 such that the outer contour of the handle 2 provided with the closure cap 27 becomes a structure that is rounded on all sides.
  • the closure cap 27 has additional features in the present case. Since, as can be seen from FIG. 1, the metering device is a knurled shaft which is longitudinally guided within the handle 2 and which must be accessible from the outside for metering the toothpaste, a longitudinal slot 28 is provided in the handle 2, in which the knurled shaft can be actuated.
  • the closure cap 27 has corresponding longitudinal tabs 29 which can be plugged onto the handle 2 in the longitudinal direction via corresponding undercuts 30, 31.
  • the undercuts 30, 31 prevent inadvertent loosening of the closure cap 27 from the handle 2.
  • the undercuts thus offer secure longitudinal guidance, which can be fixed in the end regions, that is to say in the assembled state, by means of assigned clip connections.
  • the case is so-called locking lugs 32, which can snap into the associated undercuts 33 of the handle.
  • closure cap 27 has two diametrically opposed longitudinal tabs 29. Consequently, the handle 2 also has corresponding opposing longitudinal slots 28 with corresponding undercuts 30. Consequently, the closure cap 27 can be plugged together with the handle 2 in two possible rotational positions. This combination of features therefore makes handling easier.
  • the metering device 5 After opening the toothbrush, ie removing the cap 27, the metering device 5 is freely accessible. The free ends of the bristles 8 open directly in front of the toothpaste outlet opening 6. Correspondingly, a required volume of toothpaste can be squeezed out of the toothpaste container 4 via the knurled shaft 5. The squeezed out volume is placed on the free ends of the bristles 8. By releasing the manual pressure on the metering device 5, self-locking occurs due to the kinematic relationship on the knurled shaft 5. The knurled shaft 5 thus remains in the last set position. At the end of its path, the knurled shaft 5 runs in front of the boundary wall of the toothbrush housing and thereby completely squeezes out the inserted toothpaste container 4 over its entire width.
  • the handle 9 together with the brush head 7 is folded out of the short end position according to FIG. 1 into the long end position according to FIG. 4b. Then the cap 27 can be put back on in order to obtain a rounded handle 2. After the handle 9 is folded out, it snaps into place this in a suitable manner in the long end position with the handle 2 and is fixed as an elongated structure.
  • the tooth brushing process can begin. A pressure of the brush head against the teeth is intercepted via the stop pair 11, so that the extended end position cannot be overstretched.
  • the toothbrush is cleaned and can then be folded up again.
  • the handle 9 together with the brush head 7 can simply be folded into the recess of the hollow handle 2 in the direction shown in FIG. 4b.
  • the exact fit between the handle and the handle closes the interior of the handle essentially airtight, so that all parts located in the interior of the handle are kept hygienically (see FIG. 4c).
  • even the areas that come into contact between the closure cap 27 and the handle 2 together with the handle with the brush head can be sealed off from one another via corresponding elastic sealing lips.
