Definitions

  • the present invention relates to a manually controllable toothpaste dispenser, and more particularly, to such devices which extract the paste or cream in predetermined amounts.
  • the present application differs from U.S. patent No. 4,508,240 mainly in that it does not require an air tight chamber but rather the pneumatic pump injects the pressurized air in the toothpaste tube directly. This simplifies the extractor device and makes it more efficient with the consequent reduction in cost.
  • Other existing devices are described in U.S. patents Nos. 1,841,275; 3,417,902; 4,234,104; 2,001,983 and 2,623,659; which show the use of mechanical compression to extract paste from tubes.
  • U.S. patent No. 2,792,856 discloses the use of negative air pressure in a two stroke device. None disclose the concept employed by the present invention which uses a pneumatic pump to create positive air pressure to urge paste from a tube.
  • Figure 1 depicts a cut-away side view of the preferred embodiment.
  • Figure 1A illustrates a detailed view of the one-way valve utilized in the preferred embodiment.
  • Figure 2 shows a front view of the present invention.
  • Figure 3 represents a back view of this invention.
  • Figure 4 is an inclined view, from the top, having the cover open.
  • the present invention is generally referred to with numeral 10.
  • it comprises a housing assembly 20, a pneumatic assembly 30, a carrier assembly 40, linkage assembly 50 and syringe assembly 80.
  • the user inserts toothbrush T inside carrier assembly 40 which is designed to accept commercially available toothbrushes.
  • Carrier assembly 40 is engaged to one end 53 of elongated arm 51 of spring loaded linkage assembly 50 so it is urged towards the front of housing assembly 20.
  • Carrier assembly 40 transmits the motion imparted by the user to linkage assembly 50 which, in the preferred embodiment is contained within housing assembly 20.
  • Linkage assembly 50 pivots around point 0 and it is, in the preferred embodiment a substantially elongated arm 51 having end 52 abutting to pump actuator 31 on piston 32 in pneumatic assembly 30.
  • Pneumatic assembly 30 is basically an air pump with a one-way valve 35 and spring 98.
  • One-way valve 35 in the preferred embodiment is a small metal ball 38, like a BB (small metal ball) captured inside compartment 33 that seals opening 36 when piston 32 compresses air inside cylinder chamber 39.
  • BB small metal ball
  • Holder 85 is rigidly mounted to or formed on hingedly mounted cover 100. Holder 85 is designed to provide a support point for pushing tube P towards syringe assembly 80 when cover 100 is closed. Holder 85 has clearance 86 which allows a small deflection on the tube P when syringe tip 81 penetrates through the tube P go through the opposite wall of tube P. The air forced out through syringe assembly 85 is compressed inside tube P thereby pushing the paste downwardly.
  • a rubber washer 99 surrounds the base of syringe assembly 80 so that when the latter penetrates inside tube P, washer 99 is pushed against the wall of tube P thereby sealing the interface between the wall and syringe assembly 80.
