Definitions

  • the present invention relates to a toothpaste dispenser according to the preamble of claim 1.
  • Toothpaste dispensers are devices designed to meter a desired amount of toothpaste from tubes or other containers containing toothpaste and apply them to a toothbrush.
  • Toothpaste is generally available bottled. This is an advantageous solution to fill, store and distribute toothpaste under clean conditions.
  • their disadvantages turn out; Depending on how much pressure is applied to the tube, which is done by hand, more or less toothpaste exits the tube, and a desired appropriate dosage is difficult.
  • toothbrushes that have a rounded handle and can not be placed on a horizontal flat surface without tipping, in that unscrewing the tube seal, grasping the tube and expressing the desired amount of toothpaste all done with one hand must be because the other hand holds the toothbrush.
  • toothpaste dispensers have already become known. These are devices that are attached to a wall - usually the bathroom wall - and have a perpendicular with the opening pointing down toothpaste tube clamped substantially vertically. Alternatively, the tube is replaced by a substantially cylindrical container.
  • the device described in the German patent application DE-A1-195 29 996 requires its own toothpaste container and is not suitable for tubes.
  • the toothpaste is pressed out of the container by a pumping action exerted by a pumping button.
  • the known devices for delivery of toothpaste are mechanically complex, not aesthetically and / or bacteriologically harmless.
  • the dosage of toothpaste is inaccurate on some devices, with small portions are not possible.
  • the known donors are only cumbersome and usually incomplete to clean.
  • the present invention has the object to overcome the disadvantages of the known devices and to provide a simple, easy-to-use and functional toothpaste dispenser.
  • the invention solves this problem and is defined in the characterizing part of claim 1; advantageous or preferred embodiments form the subject of the dependent claims.
  • toothpaste tubes are used, which consist of a thermoplastic material and behave elastically, namely after lateral mechanical stress have a tendency to return to their original shape when the stress is released.
  • the invention is not suitable for tubes of tin and similar plastically deformable materials; This is not a serious disadvantage, because nowadays almost all toothpaste tubes are made of plastic and are elastically deformable.
  • These common tubes are in general furnished and intended to be placed with the screw down.
  • the screw cap of the toothpaste tube has a size which is equal to or only slightly smaller than the diameter of the tube, which is thus stable.
  • the toothpaste in the tube has only a relatively low viscosity, so that the toothpaste in the tube flows down against the outlet when the tube is closed and placed with the closure down, so that the next time you use toothpaste on Outflow is available.
  • the elastic restoring force of the toothpaste tube is usually sufficient to take the relaxed state again after removal of toothpaste, i. E. Tubendschreiber, which are pivotally hinged to the toothpaste dispenser, due to their original position and at the same time to protect the tube by means of flaps or wings, which are arranged on the pushers against the outflow of other toothpaste and against drying out at the tube mouth.
  • said spring element is preferably a compression spring, which acts on the device for the rotational connection of the two tube pushers and biases the pushers in the direction of their rest position.
  • the device for the rotational connection of the two tube pushers is preferably in two intermeshing gears, which are located inside the housing of the toothpaste dispenser (behind the front wall) and each rotatably mounted on a pivot pin. Since the pushers perform only a relatively small angle of rotation between the rest position and the working position, it is sufficient to provide only toothed segments instead of full gears.
  • An alternative to the synchronized movement of the two tube pushers consists in a simple lever mechanism, which ensures a synchronous, but opposite movement of the pushers.
  • This lever mechanism is rotatably connected via pivot pins with the tube presses and can also be accommodated inside the housing.
  • the Tubendrücker are preferably used in sections of the tube support through which the pivot pin pass, and rotatably connected to these bolts.
  • By appropriate shaping of the tube pushers it is possible to make them removable from the pintles in the radial direction, whereby a thorough cleaning of the toothpaste dispenser is facilitated.
  • the toothpaste dispenser according to the invention is characterized by particularly simple operation. He is also comfortable and yet thoroughly clean. An unwanted leakage of toothpaste at rest is prevented by a special, spring-loaded flap closure, which is opened simultaneously with a pressure load of the toothpaste tube and accordingly requires no special operation.
  • FIGS. 1 to 6 show a first embodiment of the device according to the invention.
  • the toothpaste dispenser is relatively simple. It has a flat housing 10, which can be arbitrarily shaped and is oval in the example shown. This housing 10 is provided for attachment to a substantially vertical (not shown) wall and has a plurality of screw holes for the purpose of attachment 12 (two of which are shown).
  • the housing 10 contains a mechanism which will be described below. As can be seen in particular in Fig. 2, the housing 10 has no rear wall, but can readily be provided with such, for example, to prevent contamination of the mechanism.
  • a tubular support 16 is formed, which is formed as a horizontal plate.
  • the carrier 16 is penetrated by two spaced apart in a horizontal plane holes 18, which pass through the front wall 14 of the housing 10. In these holes pivot pins 20 are used, the front ends in bolt heads 22.
  • a vertical threaded hole 24 is formed with internal thread, which matches the external thread of the toothpaste tube 26, and such a tube can be screwed into the threaded hole 24 from above after removal of the cap.
  • the thickness of the tube carrier 16 is selected such that the mouth 28 of the toothpaste tube 26 protrudes downward slightly beyond the tube carrier 16 (FIG. 2).
  • the tube carrier 16 may be designed to be interchangeable, so that tube carrier 16 with different threaded holes 24, adapted to the Zahnpastatube, can be used.
  • the tube carrier 16 is provided with two lateral, mutually parallel incisions 30 on both sides of its central axis A, which is perpendicular to the front wall 14 of the housing 10, wherein the incisions also extend parallel to the central axis A and each having the same distance from this axis A (FIG. 6).
  • the correspondingly shaped lower portion 34 and 35 of two approximately L-shaped pushers 32, 33, which are mirror images of each other, is penetrated by a bore 36, in each of which a pivot pin 20 is inserted such that it first the front portion of Tubenxx 16, then the bore 36 in the lower part 34 of a pusher, then the remaining part of the tube carrier with the bore 18 and finally the housing front wall 14 passes through and then projects freely backwards into the housing 10.
  • each pivot pin 20 and the associated pusher with the bore 36 in the lower pusher region 34 is provided.
  • This connection is not shown in the drawings and can be implemented in a variety of known ways, for example by the bolt 20 is provided with a keyway and the bore 36 with a mating longitudinal wedge, or by the bolt 20 laterally flattened and the bore 36 thereto is shaped appropriately. It is also possible, the bore 36 to be dimensioned so that the pivot pin 20 engages with Passitz, in addition, even sticking comes into consideration. A connection by means of threads is conceivable.
  • the coupling members may be gears that mesh with each other and pressed onto the inner, free ends of the pivot pin, glued or otherwise connected in rotation with the respective pivot pin. Because of the relatively small angle of rotation that the pushers have to perform for the operation of the toothpaste dispenser, even the use of toothed segments is sufficient.
  • the pushers 32, 33 to couple by means of a simple lever mechanism for opposing synchronous movement.
  • This lever mechanism is not shown and is preferably housed inside the housing 10.
  • Each pintle carries a tab which is attached to the one bolt up and the other bolt down. The ends of the tabs are hinged to a crossbar. If one of the bolts rotates, for example, to the left, this movement is converted to the right via the two lugs and the traverse into a corresponding movement of the other pivot pin.
  • a tension spring 44 is attached to the two gears 38, 40 in the example shown, which still fulfills another, to be described below task.
  • a closure wing 42, 43 (see in particular Fig. 2) formed, which initially goes obliquely downwards and then bent inwards.
  • the top of the vanes 42, 43 is flat and may be provided with a sealing coating.
  • a toothbrush pad 46 is spaced apart on the housing, i. usually formed on the front wall 14, in such a distance from the tube support 16, that space for a toothbrush 48 and the réelletragende thereon portion of toothpaste remains.
  • This pad 46 may be formed so that the toothbrush 48 temporarily held, for example, is clamped between horizontal leaf springs.
  • All parts of the toothpaste dispenser can be made of suitable thermoplastic or elastomeric plastics, for which injection molding is considered, with special parts such as the tension spring 44 made of metal because of the particular demands placed on them.
  • the toothpaste dispenser according to the invention is actuated and used as follows:
  • a toothpaste tube which consists of an elastically yielding material, usually of a corresponding thermoplastic material with sufficient hardness and wall thickness. Then the closure of the tube is unscrewed and the sealing lip, if present, is removed. Thereafter, the Zahnpastatube is screwed as far as possible with the open lid thread down into the holder 16, but so that the flat clamp closure is perpendicular to the housing 10 at the bottom of the tube. The mouth of the tube over the bracket 16 is a few millimeters down.
  • the toothpaste dispenser is now in the position shown in Fig. 1.
  • the closure vanes 42, 43 rest on the tube mouth from below and are held there by the force of the spring 44, which tends to press the pushers 32, 33 apart via the toothed wheels 38, 40.
  • the toothbrush 48 is placed on the toothbrush pad 46 and optionally clamped there.
  • a lateral force on one or both pushers 32, 33 is exercised, it being sufficient to operate only one pusher, since the two pushers are mechanically connected to each other.
  • the toothpaste tube is opened by the closure vanes 42, 43 being pivoted downwards.
  • the upper portions of the pushers 32, 33 press on the tube 26, so that a certain amount of toothpaste flows out of the tube and rests on the bristles of the toothbrush 48.
  • the amount of toothpaste pushed out is controlled by the force exerted on the two pushers and the time this actuation is maintained.
  • FIGS. 7 to 11 show a second embodiment of the device according to the invention, which allows even easier operation, with only one hand.
  • the second embodiment has a very similar construction as the first embodiment.
  • This second embodiment also has a flat housing 10 with screw holes 12 and a front wall 14, a tube support 16 for a toothpaste tube 26 inserted with the opening downwards, and two in the tube support 16 pivotally inserted L-shaped pushers 32, 33 on.
  • the pivot pins 20 (FIG. 10), which are inserted into bores of the tube carrier 16 and protrude through the front wall 14 of the housing 10 into its interior, there are provided with toothed wheels or toothed segments 38, 40, which are coupled to a tension spring 44 ,
  • the housing 10 is laterally provided with a mounting bracket 50 ( Figures 7-9 and 11) which provides laterally supporting attachment of the toothpaste dispenser to the wall e.g. a bathroom allowed.
  • the mounting bracket 50 also has mounting holes 52; its purpose will be explained below.
  • the toothbrush 48 is brought from the side to the support 46A (which corresponds to the support 46 in Figs. 1-6).
  • this support 46A is designed such that the toothbrush 48 is no longer brought from the front, but from the side (from the right in Figs. 7 to 11).
  • the support 46A is designed to be laterally displaceable; For this purpose, it has as upper end a rear and a front slide rail 54 with the profile of a horizontal U, which extend parallel to the housing front wall 14 on the one hand and to the tube support 16 on the other hand (see in particular FIGS. 10 and 11). These slide rails overlap corresponding L-shaped, integrally formed on the underside of the tube support 16 guide rails 56th
  • the support 46A (which in this embodiment is displaceable in the lateral direction relative to the support 16) has an actuating lug 60 in front and behind (FIG 10), which is pierced by a respective vertical slot 62. In these slots protrudes an actuating pin 64 which is mounted or molded down at right angles to a pivot arm 66, whose width is slightly smaller than the free distance between the two actuating tabs 60.
  • the pivot arm 66 forms a downward continuation that pusher, which is the recess 58 of the toothbrush pad 46A opposite.
  • the toothbrush support 46A has a passage opening 68, which is elongated in the direction of movement of the support and closes the downward opening of the toothpaste tube 26 in the rest position of the device. This condition is shown in FIG.
  • the support 46A shifts, and the tube 26 is opened, since the passage opening 68 passes under the outlet opening of the tube 26.
  • Toothpaste begins to flow from the tube 26 to the toothbrush 48 or can now be expressed.
  • the toothbrush is further subjected to lateral, axially directed pressure, i. in Fig. 8 to the left, which transmits over the support 46A, the slot 62 of the tab 60, the pin 64 and the pivot arm 66 on the pushers 33, 32, whereby the coupled via the gears 38 and 40 pusher for compressing the toothpaste tube 26 are caused.
  • lateral, axially directed pressure i. in Fig. 8 to the left
  • This allows the flow of toothpaste in a controlled amount. This condition is shown in FIG.
  • the toothpaste dispenser in the second embodiment can be operated by one hand by an axial pressure on the toothbrush 48 laterally displaces the rest 46A and ultimately delivers toothpaste in this way.
  • the mounting bracket 50 serves to accommodate the lateral thrust exerted by the user on the device during toothpaste dispensing.
  • the invention is not limited to the embodiments described above, but expressly includes all functional and constructive equivalents and the developments of the subject invention.
  • the front wall 14 of the housing 10 can be made transparent at least in the region of the toothpaste tube 26 screwed in, and a light source can be provided behind it. This allows next to a discrete room lighting the monitoring of remaining in the tube toothpaste supply, if the tube is sufficiently translucent.
  • the cleaning of the toothpaste dispenser according to the invention can be substantially facilitated if the pushers 32, 33 are easily removable.
  • This can be achieved, for example, by first using flattened pivot pins on opposite longitudinal sides. Then, the lower portions 34, 35 of the pushers are downwardly open so far that they can be pushed over the pivot pins from above and pulled away from them in the opposite direction. Finally, it is still necessary in this case to provide a barrier which releasably holds the pushers on their respective bolts. This can be achieved by using a flat, slightly corrugated leaf spring.
  • the actuating pin on the actuating tab 60 and the slot 62 may be attached to the pivot arm 66.
  • the device according to FIG. 7 to 11 can be performed in mirror image, so that the mounting bracket is right and the toothbrush 48 is to be inserted from the left.
  • the device can be supplied as a kit and assembled so that the toothbrush can be inserted from the right (as described above), but also from the left.
  • the mounting bracket can be mounted on the right side, left side, top or bottom of the device, depending on the possibility of attachment on site.
