Definitions

  • This invention relates to a dispenser for paste materials, such as cosmetic creams or toothpastes.
  • Conventional toothpaste tubes suffer from a number of disadvantages. For example, they are aesthetically unpleasing and cause undesirable waste of. toothpaste which becomes trapped in the squeezed tube during use.
  • Free-standing toothpaste dispensers are known, in which the paste is discharged from a nozzle by applying manual pressure to a discharge valve adjacent the nozzle.
  • paste material becomes trapped between the valve and the nozzle outlet, and that drying out of this excess paste tends to cause undesirable blockage of the nozzle.
  • a free-standing dispenser for paste material comprising a housing for the material and an outlet orifice communicating with the housing, a piston axially movable in the housing towards the orifice and provided with restraining means to prevent axial movement in a direction away from the orifice, and a resilient, compressible member connected to the housing at the end thereof remote from the orifice and arranged so that compression of the member causes movement of the piston towards the orifice, thereby pumping paste material out of said orifice, and release of the compression on the member causes the piston to remain stationary relative to the adjacent walls of the housing.
  • the housing is generally cylindrical and is free-standing on a base which consists of or includes the compressible member.
  • Paste material may be ejected from the orifice by applying hand pressure to the housing against the resilience of the compressible member.
  • the compressible member may be a spring loaded pad, but preferably it comprises a resilient plastics cup having a flexible wall attached to the housing, the wall being deformable under the action of a compressible force.
  • the piston may have a centrally located passage through which passses an elongate guide rod attached to the compressible member, and frictional engagement between the rod and piston is designed to prevent movement of the piston away from the orifice.
  • frictional engagement between the piston and wall of the housing may be provided which prevents movement of the piston away from the orifice.
  • the piston may be shaped to conform substantially to the internal shape of the upper end of the housing, so that when the piston reaches its uppermost position little paste material is trapped between the piston and housing.
  • the housing and compressible member may, if desired, be encased in an outer shell, and the housing will suitably be a sliding frictional fit in the shell. This enables the dispenser to be used either freely in the hand or when standing on a horizontal surface, in addition to improving the aesthetic appeal of the dispenser.
  • a toothpaste dispenser comprises a cylindrical plastics housing 1 having a curved nozzle 3 and supported on a base in the form of a resilient plastics cup 5.
  • the cylindrical wall 7 of the cup 5 is curved inwardly and the rim of the wall is received in an annular groove 9 formed in the housing 1.
  • the base of the cup 5 has a socket 11 in which a plastics rod 13 is located and retained therein by friction or by a suitable adhesive.
  • the base of the cup 5 also has a small passage 15 formed therein to permit the flow of air between the interior of the housing 1 and the exterior during use.
  • a piston 17 is slidably mounted on the rod 13, and consists of a plastics moulding 19 attached to a steel star ring 21.
  • the moulding 19 has a domed upper portion 23 and a pair of outwardly flared cylindrical walls 25, 26, which contact the wall of the housing 1.
  • the star ring 21 includes eight inclined, radially extending tangs 27 spaced circumferentially and equidistantly around the ring and which are designed so as to bite into the inner wall of the, housing 1, when the piston 17 is forced towards the base of the housing thereby preventing downward movement of the piston.
  • the tangs 27 can bend slightly downwardly to reduce the diameter of the circle circumscribing the tangs and hence permit the piston 17 to move up the housing.
  • the ring 21 also includes four inwardly directed, inclined tangs 29 which are spaced circumferentially around the rod 13.
  • the tangs 29 grip the rod 13 and when the rod is pushed towards the nozzle 3 the grip increases due to the reduced inclination of the tangs and the piston 17 is thereby carried up the housing 1 by a distance equal to the longitudinal movement of the rod.
  • the gap between the tangs 29 opens slightly to permit unobstructed movement of the rod 13 through the piston.
  • Attached to the nozzle 3 is a projecting shoulder 31 which can receive downward pressure from a thumb or finger during operation of the dispenser.
  • the dispenser is also provided with a cap 33 which clips over the nozzle 3 and helps to prevent the contents of the dispenser from drying out.
  • the housing 1 is slidably mounted in an outer cylinder shell 35, which also includes an internal annular groove 37 at its lower end to receive an annular locating rib 39 on the cup 5.
  • the shell 35 is provided with a shoulder 41 to receive and locate the cap 33 on the dispenser.
  • cup 5 can be replaced by other types of spring loaded devices which will function in a similar manner.
