Definitions

  • the two units, each integrally molded, are assembled and mounted on the container by relatively simple operations involving minor deformation of certain portions of the stationary unit.
  • FIGURE 1 is a longitudinal sectional view of the stationary unit of a dispenser embodying the principles of the invention, as molded or cast and prior to deformation;
  • FIGURE 2 is a sectional view corresponding to FIG- URE 1, showing the stationary unit after deformation to secure the same to a container cap;
  • FIGURE 3 is a longitudinal sectional view showing the stationary and movable units in assembled relation prior to deformation of the stationary unit to provide an interlock between the units for the purpose of maintaining assembled relationship thereof;
  • FIGURE 4 is a sectional view corresponding to FIG- URE 3 at the conclusion of the step of deforming the stationary unit to provide the aforesaid interlock with the reciprocable unit;
  • FIGURE 5 is a longitudinal sectional view of the completed dispenser showing the two units in collapsed and temporarily locked relation, in which relation they are sealed against leakage for shipping, and
  • FIGURE 6 is a transverse section taken substantially on the line 6-6 of FIGURE 5.
  • FIGURE 1 in which is illustrated the stationary unit of the dispenser after molding and prior to deformation, it will be perceived that this unit comprises a cylindrical barrel 12, a depending suction tube 13, and a collar portion 14.
  • the collar portion 14 is formed at the upper end of barrel 12, noting that throughout the following description the dispenser will be assumed to occupy the upright position in which it is normally used.
  • Elements 12, 13 and 14 are molded or cast integrally, this being made possible by the contour of the structure, which lends itself well to a single injection molding operation.
  • the upper end of the barrel 12 is preferably slotted at circumferentially spaced points as indicated at 18 and as shown in FIGURE 6, for the purpose of preventing the formation of an airlock in the barrel 12 above the piston, to permit ingress to the container of air in order to replace discharged liquid, and to allow drainage into the container of liquid which may pass the piston and which would otherwise be trapped in the upper portion of barrel 12.
  • Cap 21 is apertured to receive collar portion 14 and is internally threaded as shown at 22 for cooperative engagement with external threads formed on the neck of the container; the usual gasket 24 is preferably employed beneath flange 20.
  • the collar portion 14 is further provided at its upper end with an interiorly threaded sleeve portion 25 of reduced diameter, forming a shoulder 26 which is subject to deformation for the purpose of locking the container cap 21 on the collar portion 14.
  • FIGURE 2 The manner in which this deformation is elfected is shown in FIGURE 2.
  • shoulder 26 for instance by means of a cylindrical tool embracing the sleeve portion 25 and shown in broken lines at 28, deforms or swages collar portion 14 sufliciently to form thereon an annular lip 30 overlying container cap 21, whereby the cap 21 is held on collar portion M against displacement, but is rotatable thereon to permit threading of the cap 21 on the container neck.
  • the stationary and reciprocable units of the dispenser may be formed of any moldable plastic materials, preferably materials commonly designated thermoplastics. Excellent results are achieved by the use of a polyethylene sold under the trademark Super Dylan by Koppers Company, Inc, of Pittsburgh, Pennsylvania. Vinyl chloride acetate is also highly effective, and in general, any plastic material subject to hot or cold flow, capable of being molded and readily deformed after molding in response to heat and/ or pressure may be employed.
  • the reciprocable unit of the dispenser is similarly molded in one piece and consists essentially of a plunger 35 a depending hollow piston 36, enlarged at its lower end to engage the interior wall of barrel 12, a head portion 37 and a discharge spout 38, the upper part of the head portion being formed to provide the usual finger piece 39 for depressing the reciprocable unit to pump liquid from the container.
  • Discharge passage 40 extending upwardly through the plunger 35 and head portion 37, communicates at its upper end with a passage 41 in the discharge spout 33, the spout being molded or cast in the form of a straight tube, and being subsequently deformed by pressure, if desired, so that its outer end is inclined downwardly as shown.
  • Passage 40 is enlarged at 44, adjacent its lower end, to receive a ball valve 45, which is introduced initially through the piston 36 and the lower end of the passage 4% and is pressed into position immediately above an annular valve seat 43 formed in the passage 40, the plunger 35 flexing sufficiently to permit the introduction of the ball valve 45 past the seat and into its operative position.
  • a plurality of circumferentially spaced lugs 49 which prevent the ball valve 45 from seating in an upward direction.
  • ball valve 45 functions in the usual manner as a one-way valve to permit flow of liquid in an upward direction only in passage 4-0.
  • a coil compression spring 52 acting to urge the reciprocable unit upwardly, the lower end of the spring being retained against lateral displacement by an annular lip 56 formed at the lower end barrel 12.
  • Ball valve 55 seating by gravity in the lower end of barrel 12 and acting as a check valve to prevent drainage of liquid downwardly from the barrel 12, is encircled by the annular lip 56.
  • the seat for ball valve 55 forms an angle of at least 45 with the axis of the dispenser to minimize the possibility of wedging of the valve in its seat; this may cause a tendency of the valve to rattle on the upward stroke of the reciprocable unit.
  • annular lip 56 having slight clearance with ball valve 55, functions to prevent such rattling.
  • Spring 52 is formed with a convolution 60 of reduced diameter, preferably adjacent each end, as shown, to provide reversibility.
  • the ball valve 55 is engaged by the adjacent small convolution 60 of spring 52 to seat the valve against displacement, thus preventing flow of liquid past the valve and outwardly through passage 40 when the dispenser is inverted.
  • the reciprocable unit is retained in the depressed position by coacting threads formed on the sleeve 25 and the head 37.
  • downwardly tapering surfaces on the head and the sleeve, indicated at 62 are pressed together to prevent discharge of liquid from the container externally of the plunger 35.
  • the container is completely sealed and loss of liquid is prevented during handling and shipping, this being of particular importance when toxic liquids such as insecticides are used.
  • FIGURE 3 shows these units assembled so as to position the piston 36 just below the upper end of barrel 12.
  • a cylindrical tool 65 shown in dot-and-dash lines, which is separable on a plane passing through its axis, is assembled around the plunger 35 and is then pressed downwardly against the upper end of barrel 12.
  • the lower end of tool 65 is so shaped as to cause the material of the barrel to flow inwardly, thus providing an inwardly directed part 66 extending into close proximity with plunger 35.
  • the part 65 will be discontinuous, but will form in effect an annular guide for the plunger, noting that the slots 18, as shown in FIGURE 6, are quite narrow in order to minimize leakage of liquid from the dispenser by accidental inversion when in use.
  • Inwardly directed part 66 also serves to prevent withdrawal of the reciprocable unit from the stationary unit, thus completing the assembly of the dispenser without the addition of the further parts commonly employed for the guiding and retention of the plunger in the barrel.
  • the head and spout illustrated herein may be replaced with a one-piece spray head fitted on the upper end of the plunger and formed as described in my pending application, Serial No. 719,427, filed March 5, 1958, entitled One Piece Aerosol Spray Head, the only modification required of the spray head therein disclosed being the formation of external threads thereon for engagement with the internal threads of the sleeve 25 as described herein.
  • a dispenser for discharging liquid from a container the combination with a cylindrical barrel for insertion in a container, of a reciprocable unit comprising a plunger, a piston at the lower end of said plunger, slidably received in said cylindrical barrel, and a discharge head at the upper end of the plunger, said plunger, piston, and head having communicating passages extending therethrough for the discharge of fluid from said container on depression of said reciprocable unit, a coil spring acting between said barrel and plunger to urge the latter upwardly, a valve element, said barrel being formed adjacent its lower end to afford a seat for said valve element to prevent discharge of liquid downwardly through the lower end of said barrel while permitting free flow of liquid upwardly into said barrel from said container, said spring being compressed between and in endwise abutment with said plunger and the lower end of the barrel around said valve seat, and having a portion between its ends normally disengaged from said valve element, but disposed for movement into direct engagement with said element in a direction to seat said element responsive to movement of the plunger to its fully
  • valve element is a ball and the lower end of said spring is formed of a series of convolutions of a diameter to define a valve cage normally permitting free movement of said ball toward and away from its seat, said portion of the spring being located between its ends and normally spaced from the ball on the side thereof remote from the valve seat.
  • a dispenser as defined in claim 3 in which said reciprocable unit is disposed for reciprocation within a range normally located above its fully depressed condition, whereby said valve element is free to seat and unseat during said reciprocation.
