Definitions

  • the invention concerns toothbrushes and toothpaste. Toothbrushes and toothpaste packed in a metal or plas- tic tube are universally known articles.
  • Subject of the invention is a dispenser of toothpaste consisting of an airtight oblong container containing both the toothpaste and a fluid propellant and compri ⁇ sing an emitting means and apart controlled 'by hand. Pressure on said part causes output, as desired, of toothpaste from the dispenser, and its distribution on the bristles, and the like, of the brush end of the toothbrush by means of the propellant.
  • the dispenser is cap-shaped, its form being substantial ⁇ ly that of a truncated pyramid with an inner entry aper ⁇ ture at the nozzle of a valve emerging at the top of the container.
  • the outer aperture has a substan ially rectangular cross section having internal dimensions practically corres ⁇ ponding to the external dimensions of the brush normal ⁇ ly forming part of a toothbrush. Therefore, by inserting the brush of the toothbrush in said external aperture or close to it, and causing the valve to open, toothpaste will be evenly spread on said brush . A certain length of the valve nozzle emerges from the top of the container pressed by an inner spring.
  • the cap of the Emitting means is fixed to the side of a hol ⁇ low body shaped substantially like a truncated cone, close to its lesser base.
  • Said truncated cone-shaped body comprises an internal axial cup-shaped part facing outward and having a hole through its base. The valve nozzle penetrates inside said cup till it nearly comes in contact with said base.
  • the internal aperture in the truncated pyramid-shaped cap communicates with the hole in said cup.
  • the emitting means can make a fair axial movement so that by pressing with a finger on the head formed by the lesser base of the truncated cone-shaped body, the nozzle of the valve can be pushed back causing said valve to open.
  • the toothpaste when pushed by the pro ⁇ pellant passes through said nozzle, through the hole in the base of the truncated cone-shaped body, through the entry aperture in the pyramidal cap, -emerging from this cap to spread uniformly over the brush part of the toothbrush.
  • the relative angle of the axis of the pyramidal cap and that of the truncated cone-shaped body is preferably about 70° - 90°. Distribution of toothpaste on the brush of the toothbrush is therefore facilitated with the container held by the hand in a moderately inclined position towards the brush of the toothbrush and with the axis of the pyramidal cap substantially coinciding with the axis of the brush.
  • the propelling fluid may be freon or chlorofluorocar- bide generally or of some other type.
  • the oblong container is associated to the head of a toothbrush in whose handle there is a longitudinal hole and in which there is a set of holes placed at the spaces between the tufts of bristles. Said handle is substantially aligned with the container. The end of said handle opposite to the brush is so placed that the longitudinal hole along it is in line with the nozzle of a valve from which the toothpaste is delivered .
  • valve nozzle projects by a certain length from the top of the container pressed by an internal spring.
  • the end of said handle, opposite to the brush end shaped like a block with an oblong base, slides axially and freely in relation to an oblong seat made in the head of the container.
  • Said block is provided with some form of external trans ⁇ versal element. Therefore by pressing the toothbrush towards the container and also pressing on said trans ⁇ versal element, a backward movement is made by the tooth- brush and also by the valve nozzle thus opening the valve and transferring toothpaste through said nozzle into the longitudinal hole in the toothbrush and out for uniform distribution over the brush.
  • the container can be taken off the toothbrush and replaced with a new one.
  • connection between the oblong seat, within which the base block of the toothbrush freely slides, and the container is made by elastic means which fit onto ridges in the head of the container, or else by ridges on said oblong seat which fit onto elastic means in the head of the container.

  • Fig. 2 Fr.ont view of the dispenser in Fig. 1.
  • Fig. 3 The same dispenser seen from above.
  • Fig. 4 The dispenser in Figs. 1-3 partially cut away and close over a toothbrush.

  • Fig. 6 Another version of the dispenser combined with a toothbrush .
  • Fig. 7 The dispenser in Fig. 6 when dispensing tooth- paste.
  • the dispenser 10 comprises the container 20 with its fixed cover 21.
  • the head 22 In the centre of said cover is the head 22 with its ax ⁇ ial hole through which passes the nozzle 23 of an inter- nal valve.
  • an emitter 30 shaped like a truncated cone having an open base 31 and a grille-type head 39.
  • a cap 36 Fixed to one side of the emitter 30 is a cap 36 shaped like a truncated pyramid having an external rectangular aperture 38 connected to the hole 34 by the internal pas ⁇ sage 35.
  • Figs. 4 and 5 show the toothbrush 11 with its handle 12 and brush 13 consisting of tufts 14 of bristles.
  • the container contains the toothpaste and a fluid propellant.
  • the dispenser 10 is brought close to the toothbrush so that the brush 13 enters the aperture 38.
  • the emitter is moved towards the container and there ⁇ fore the nozzle 23 towards the internal valve causing said valve to open.
  • FIGs. 6 and 7 illustrate another execution 50 consist ⁇ ing in association of the toothbrush 80 with the oblong container 51 substantially similar to the container 20 in Figs. 1-5.
  • the container contains toothpaste and fluid propellant. AS!. he top of the container there is a fixed cover 52 with its head 55 and a groove 53 below it.
  • the toothbrush 80 has a handle 81 in which there is a longitudinal hole 82.
  • Holes 84 are made through the surface carrying the tufts of bristles 86 forming the brush 85.
  • the hollow base 90 At the end of the toothbrush 80 opposite to the brush 85 is the hollow base 90 in which there is an internal cup 92, open outwards , there being in its base 93 the hole 91 connected to the longitudinal hole 82 in the handle 81 by means of the passage way 83.
  • the nozzle 60 connected to the valve inside the contain- er 51, emerges from. the head 55 on the container's cover 52.
  • the toothbrush 80 is pushed outward by the spring 61 in ⁇ side the tubular body 70 and is held firm by ridges 73 on said tubular body 70 which press into the seats 91 made in the base 90 of the toothbrush.' On the outward end of the base 90 there is an external trans ⁇
  • the bottom 93 of the cup 92 moves the nozzle 60 inside the container and this opens the internal valve.
  • the valve opens, the toothpaste 87 in the container passes through the nozzle 60, through the hole 94 and passage way 83, along the longitudinal hole 82 and through the holes 84 made ⁇ mong the tufts of bristle from where it spreads all over the brush 86.
