Definitions

  • the size of the v outlet is so proportioned with respect to the viscosity M90922 gal or resistance to change of the fluent mass that retro- ;1963 S 23 et 222/387 grade flow of the fluent mass back through the con- 3'20] 8/1965 vyark TE X tainer outlet is restricted upon release of the squeezing 3521795 7/1970 Langhlelm etal.
  • the present invention relates to dispensers for fluent materials, and more particularly to a container from which the fluent material is dischargeable, and in which the effective volume of the container decreases in accordance with the volume of the material dispensed.
  • dispensers are illustrated in which squeezing of a pliant, elastic head at the forward portion of the container, or squeezing of the container itself at an appropriate region, forces a fluent mass through adischarge outlet, release of the squeezing force effecting automatic closing of an outlet valve and creation of a subatmospheric or partial vacuum in the container, which enables atmospheric pressure to shift a follower or piston, located rearwardly of the mass, in a forward direction within the container to compensate for the volume of material disclaimedd.
  • the follower piston device is prevented from return movement-in U.S. Pat. No.
  • a discharge valve is not required that closes automatically upon relieving of the deformation force on the container head or other container part, withresultant development of a partial vacuum in the container forwardly of the piston.
  • the discharge outlet or nozzle is open continuously. Advantage is taken of the viscosity of the material in the container, its tensile strength, or both, to cause the fluent material or mass to resist withdrawal back into the outlet or nozzle, the atmospheric pressure acting upon the follower or piston to shift it in a forward direction against the mass.
  • the nozzle or outlet size and length are so proportioned with respect to the fluent mass in the container that there is very little tendency for the mass to withdraw into the outlet, such resistance to retrograde flow of the material through the outlet causing the atmospheric pressure to force the piston in the forward direction by an amount substantially corresponding to the volume of the mass dispensed from the container.
  • the resistance to withdrawal of the mass back through the discharge opening can be increased by providing one or more discontinuities in the path of the mass moving through the discharge outlet, such as steps, change in direction or change in cross-section through the opening. This produces greater resistance to rearward movement of the viscous mass back through the outlet, and greater assurance that the follower piston will move in the forward direction upon release of the deforming force on the head of the container, or other parts of the container, and the return of the head or other container part to its initial shape,
  • FIG. 2 is an enlarged fragmentarysection through the rear portion of the container disclosed in FIG. 1;
  • FIG. 3 is an enlarged cross-section taken along the line 33 on FIG. 1.'
  • the dispenser includes a container 10 of any suitable material that may have a main body 11 of cylindrical shape, and which is adapted to contain a fluent mass (not shown), such as toothpaste, cosmetic, syrup, molasses, honey, or similar material of relativelyhigh viscosity.
  • the container includes a rear closure or endwall 12 secured thereto by a circumferential rib 13 on the closure fitting within a companion circumferential groove 14 at the rear end of the container body, this rear wall has a vent hole or aperture 15 therethrough to permit entry of the ambient air into the container for action upon a one-way follower or piston device 16 slidably in the container.
  • the follower device is movable in a forward direction, after dispensing of a portion of the fluent mass or materialfrom the container, being caused to shift in the container a distance correspond ing to the volume of the fluent material discharged through a forward container outlet passage, nozzle or spout 17, which forms part of a hollow head or dome 18 of pliant, elastic material.
  • the head is suitably secured to the forward end of the container body 11 by a circumferential rib 19 on the head received within the companion circumferential groove 20 of the container.
  • the piston includes a main body 22 having a central hub 23 and an outer rim 24, with intervening stiffener ribs 25 interconnecting the two parts for relative rigidity.
  • the main body may be made of a suitable material, such as polyethylene, being provided with a forward lip seal 26 extending laterally outwardly of the rim 24, and a rearward lip seal 27 extending laterally outwardly from the rim.
  • the fingers 31 press fitted upon the periphery of the central por-' tion or hub 23 of the follower piston body, this central portion being integral with flexible radial fingers 31 extending therefrom, the fingers deflecting about hinge lines 32 where they join the central portion 30 as the latch device is inserted into the container body through its rear end prior to mounting of the rear closure 12 in the container body.
  • the fingers 31 incline in a transverse and rearward direction, with their outer ends 33 engaging the container wall 28.
  • the arrangement is such that the fingers 31 merely slide along the inner wall of the container when the follower device 16 moves in a forward direction within the container under the influence of atmospheric pressure, but any tendency of the follower device to move rearwardly in the container causes the outer ends 33 of the fingers to grip or latch against the inner wall of the container.
  • the one-way latch device 21 is made of a suitable flexible material, such as steel, phospor bronze, acetal, and the like.
  • a suitable cover 35 may be disposed over the nozzle or spout 17 and over the entire hollow heador dome 18, as illustrated in phantom lines in the drawings. This cover is frictionally retained on the head 18, but is readily removed when the dispenser is to be used.
  • the nozzle or spout 17 of the hollow head or dome may be used alone, without the L-shaped extension 17a illustrated in the drawings. If the latter is used, it is secured to the nozzle 17 by a circumferential rib 40 on the extension fitting into a circumferential nozzle groove 41.
  • the nozzle passage 17b is of such area and length as to permit outward flow of the viscous mass through the nozzle under the pressure imposed on the mass by deformation of the head 18.
  • area and length are so related to the physical characteristics of the fluent mass that resistance to retrograde flow of the mass is provided upon development of the vacuum condition resulting from reassumption of the head of its normal, initial shape.
  • the L-shaped extension can be added to the nozzle 17. This causes the fluent mass to drastically change its direction of movement through the extension, introducing resistance to flow of the mass, particularly retrograde flow of the mass through the nozzle structure 17, 17a. Resistance to flow of the mass into and through the nozzle or spout structure 17, 17a, and its retrograde movement, can be further en hanced by changing the shape of the passage 17d through the outer portion of the nozzle, as, for example, by forming it of oval shape, as disclosed in FlG. 3.
  • a dispenser a container; a viscous fluent mass in said container; said container having a forward continuously open elongate discharge outlet; piston means in said container movable in a forward direction toward the outlet and against the mass in the container; means for restricting movement of said piston means in a rearward direction away from said outlet at all axial positions of said piston means in said container while permitting movement of said piston means in the container in the forward direction; means for reducing the volume of the container forwardly of the piston means to dispense a portion of the mass through said open discharge outlet; means for then increasing the volume of the container forwardly of the piston means to produce a partial vacuum in said container forwardly of said piston means; the cross-sectional area of said outlet and the length of said open outlet being so related to the viscosity of said fluent mass that said partial vacuum is incapable of effecting significant withdrawal of said mass back into said outlet, whereby air at atmospheric pressure moves said piston means forwardly in said container toward said outlet.
  • saidrestricting means comprising one-way latch means on said piston means engageable with the inner wall of said container to prevent substantially all movement of said piston means rearwardly in said container.
  • said container including a forward pliant, elastic head portion containing said discharge outlet, deformation of said pliant, elastic head portion effecting said reduction in the '5 volume of said container forwardly of the piston means.

  • elongate nozzle means providing said dischargeoutlet.
  • elongate nozzle means providing said discharge outlet, the outer portion of said nozzle means being disposed at a substantial angle to the inner portion of said nozzle means.
  • said restricting means comprising one-way latch means on said piston means engageable with the inner wall of said container to prevent substantially all movement of said piston means rearwardly in said container; said container including a forward pliant, elastic head portion containing said discharge outlet, deformation of said pliant, elastic head portion effecting said reduction in the volume of said container forwardly of the piston means; elongate nozzle means providing said discharge outlet.
