Definitions

  • This invention relates to a fluid dispenser device, more particularly to a fluid dispenser device adapted for mounting at a top open end of a container containing fluid therein, especially liquid with grains suspended therein.
  • a conventional liquid dispenser device is shown to include a tubular mount 3 adapted for mounting at a top open end of a container 1 containing liquid therein and defining an accommodation chamber, a surrounding retaining cap 2 threadedly engaged to the top open end of the container 1, and a surrounding retaining collar 4 disposed on the surrounding retaining cap 2 so as to secure the tubular mount 3 to the top open end.
  • a tubular plunger 5 is movable relative to the tubular mount 2, and has a passage fluid-tightly connected to and fluidly communicated with the accommodation chamber of the tubular mount 3 by means of a seal ring 503.
  • Inlet and outlet valves 301,504 are disposed in an inlet of the accommodation chamber of the tubular mount 3 and an outlet of the passage of the plunger 5, respectively.
  • a spout 6 is connected to the tubular plunger 5 for discharging liquid in the container 1.
  • depression of the plunger 5 can move the seal ring 503 downwards against biasing action of a spring 8 received in the accommodation chamber of the tubular mount 3 so as to squeeze the liquid and air out of the spout 6.
  • a reduced pressure is created in the accommodation chamber once the seal ring 503 and the plunger 5 are returned to their original position by means of the spring 8, thereby suctioning the liquid in the container 1 through the inlet valve 301 to replenish the accommodation chamber.
  • the conventional liquid dispenser device can be applied to the container 1 for dispensing the liquid contained therein, such as liquid detergent, bath gel and shampoo.
  • the conventional liquid dispenser device is not suitable for dispensing liquid with grains suspended therein because the grains may be trapped between the seal ring 503 and an inner surface of the tubular mount 3 to obstruct sliding movement of the seal ring 503 and to diminish the air-tight effect of the seal ring 503, thereby adversely affecting the movement of the plunger 5 and the biasing action of the spring 8.
  • the object of the present invention is to provide a fluid dispenser device which can prevent wearing of component parts thereof and which can be operated smoothly.
  • the fluid dispenser device includes a tubular mount having a surrounding wall which surrounds an axis, which defines an accommodation chamber therein, and which has an upper surrounding portion that is adapted to be fitted in a top open end of a container, and a lower surrounding portion that is opposite to the upper surrounding portion and that has an intake port adapted for suction of fluid in the container therethrough.
  • a volume variable member is received in the accommodation chamber, and defines a passage therein, which extends along the axis.
  • the passage includes an inlet end which is fluid-tightly secured to the lower surrounding portion and which is disposed in fluid communication with and downstream of the intake port, an outlet end which is disposed downstream of the inlet end and which is opposite to the inlet end along the axis, and an intermediate portion which is interposed between the inlet and outlet ends and which is configured such that the outlet end is movable between an expanding position, where the outlet end is away from the intake port so that the passage has a larger volume, and a collapsed position, where the outlet end is close to the intake port so that the passage has a smaller volume.
  • a tubular plunger has a surrounding plunger wall which defines a conduit therein.
  • the plunger wall includes a surrounding depressing portion which is fluid-tightly secured to the outlet end of the passage such that the conduit is fluidly communicated with the passage, and which is movable relative to the surrounding wall of the tubular mount along the axis so as to bring the outlet end to move between the expanding and collapsed positions, and a surrounding actuated portion which extends from the surrounding depressing portion outwardly of the upper surrounding portion so as to be actuated to move the outlet end toward the collapsed position, thereby squeezing the fluid out of the passage and creating a reduced pressure in the passage once the outlet end is returned to the expanding position.
  • a biasing member is disposed to bias the outlet end towards the expanding position, thereby suctioning the fluid in the container through the intake port to replenish the passage by virtue of the reduced pressure created in the passage.
  • An inlet valve member is disposed upstream of the intake port.
  • the inlet valve member permits the fluid in the container to flow into the passage of the volume variable member only, and prevents the fluid from flowing back into the container when the fluid in the passage is squeezed.
  • An outlet valve member is disposed downstream of the surrounding depressing portion of the conduit.
  • the outlet valve member permits the fluid in the passage and the conduit to flow out through the conduit only when the fluid in the passage is squeezed, and helps create the reduced pressure in the passage by virtue of closure of the outlet valve member when the outlet end is returned to the expanding position.
  • a fluid dispenser device according to the present invention is shown to be adapted for mounting at a top open end of a container 100 containing liquid therein, such as shampoo, liquid detergent with scrubbing grains suspended therein, etc.
  • the fluid dispenser device is shown to comprise a tubular mount 20, a surrounding retaining cap 10, a surrounding retaining collar 30, a dipping tube 60, a volume variable member 90, a biasing member 80, a tubular plunger 40, and a spout 50.
  • the tubular mount 20 has a surrounding wall 21 which surrounds an axis (L) , which defines an accommodation chamber 23 therein, and which has an upper surrounding portion 211 and a lower surrounding portion 213 opposite to each other.
  • a radially extending flange 212 extends from the upper surrounding portion 211 radially and outwardly, and is adapted to be mounted on the top open end of the container 100.
  • the retaining cap 10 has a surrounding top wall 12 which defines a circular hole 11 therein and which has a periphery, and a surrounding threaded wall 13 which extends downwardly from the periphery of the surrounding top wall 12.
  • the upper surrounding portion 211 of the surrounding wall 21 of the tubular mount 20 passes through the circular hole 11 such that the top wall 12 is disposed on the radially extending flange 212.
  • the threaded wall 13 is engaged threadedly with the top open end of the container 100.
  • the surrounding retaining collar 30 is press-fitted onto the upper surrounding portion 211 so as to force the radially extending flange 212 to abut against the top wall 12, thereby securing the tubular mount 20 to the container 100.
  • the lower surrounding portion 213 has a bottom wall portion 22 which defines an intake port 221 adapted for suction of the fluid in the container 100 therethrough.
  • the dipping tube 60 has a connecting portion 61 which is connected to and which is fluidly communicated with the lower surrounding portion 213, and a tube portion 62 which extends downwardly from the connecting portion 61 and which is adapted to dip into the liquid in the container 100.
  • An inlet valve member 63 includes a valve seat 631 which is formed integrally with the tube portion 62 and which extends towards the axis (L) in radial directions, and a ball 632 which is detachably engaged with the valve seat 631 so as to open and close the valve seat 631.
  • a porous member 71 is disposed on the connecting portion 61 so as to deny entry of the ball 632 into the accommodation chamber 23.
  • a tubular stem 70 extends from the porous member 71 along the axis (L).
  • the volume variable member 90 is made from a flexible material, and is configured to have a bellows shape.
  • the volume variable member 90 is received in the accommodation chamber 23, and defines a passage 94 therein, which extends along the axis (L).
  • the passage 94 includes an inlet end 91 which is fluid-tightly secured to the connecting portion 61 and which is disposed in fluid communication with and downstream of the intake port 221, an outlet end 92 which is disposed downstream of the inlet end 91 and which is opposite to the inlet end 91 along the axis (L), and an intermediate portion 93 which is interposed between the inlet and outlet ends 91, 92 and which is configured such that the outlet end 92 is movable between an expanding position, where the outlet end 92 is away from the intake port 221 so that the passage 94 has a larger volume (as shown in Fig. 4) , and a collapsed position, where the outlet end 92 is close to the intake port 221 so that the passage 94 has a smaller volume (as
  • the biasing member 80 is a coil spring 80 which is received in the passage 94 and which is sleeved on the tubular stem 70 so as to firmly bias the outlet end 92 towards the expanding position.
  • the tubular plunger 40 has a surrounding plunger wall 41 which defines a conduit 412 therein.
  • the plunger wall 41 includes a surrounding depressing portion 421 which is fluid-tightly secured to the outlet end 92 of the passage 94 such that the conduit 412 is fluidly communicated with the passage 94, a surrounding flange portion 42 which extends outwardly and radially from the surrounding depressing portion 421 such that the surrounding flange portion 42 is in slidable contact with an inner surface of the surrounding wall 21 of the tubular mount 20 so as to stabilize the movement of the outlet end 92 along the axis (L) between the expanding and collapsed positions, and a surrounding actuated portion 411 which extends from the surrounding depressing portion 421 along the axis (L) and outwardly of the surrounding retaining collar 30.
  • the spout 50 is connected to the surrounding actuated portion 411, and is fluidly communicated with the conduit 412 for discharging the liquid from the conduit 412.
  • a flexible strap 52 has one end retained between the surrounding retaining cap 10 and the surrounding retaining collar 30, and the other end provided with a stopper 521 which is disposed to detachably plug the spout 50 so as to prevent flow of the liquid through the spout 50 when the container 100 is unintentionally squeezed.
  • an outlet valve member 43 includes a valve seat 431 which is formed integrally with the surrounding plunger wall 41 at a position between the surrounding depressing portion 421 and the surrounding actuated portion 411, and which extends towards the axis (L) in radial directions, and a ball 432 which is detachably engaged with the valve seat 431 so as to open and close the valve seat 431.
  • the outlet end 92 is returned to the expanding position by virtue of the biasing action of the coil spring 80, thereby creating a reduced pressure in the passage 94 and the conduit 412.
  • the liquid in the container 100 is suctioned through the inlet valve member 63 and the porous member 71 to replenish the passage 94 and the conduit 412 by virtue of the reduced pressure for a next dispensing operation.
  • the ball 432 of the outlet valve member 43 closes the valve seat 431 so as to help maintain the reduced pressure.
  • the inner surface of the surrounding wall 21 will not be subject to the grinding action of the grains suspended in the liquid, thereby ensuring the smooth sliding movement of the surrounding flange portion 42 along the inner surface of the surrounding wall 21 and the biasing movement of the coil spring 80.
  • the service life of the tubular mount 20, the tubular plunger 40 and the coil spring 80 can be thus prolonged.
