Definitions

  • the present invention relates to a spray pump improved to permit the fixing and holding of nozzle port of a spray head at a position determined beforehand optimumly from the requirement by the construction of the pump, as well as from the view point concerning the advertising design on the surface of the container.
  • the nozzle port of the spray head is directed in the same direction as the bend of the suction pipe suspended from the lower end of the pump structure towards the bottom of the container.
  • the nozzle port of the spray head is directed forwardly so that the spray may made in the same direction as the display of the goods name and the advertising design.
  • connection between the spray head and the valve stem is made through a friction fitting engagement between the outer periphery of the upper end of the valve stem and a bore of a rather large diameter formed in the lower end of the spray head in communication with a vertical passage formed in the spray head. Since this friction fitting engagement is not so tight, it is often experienced that an unintentional relative rotation is caused between the spray head and the valve stem during the use. An inadequate use of the spray container impairs the performance of the pump seriously or make the pump inoperative, even though there is no defect in the pump structure. This cannot be expected by the manufacturer. For instance, the rotation of the valve stem within the cylinder may occur however the connection between the spray head and the valve stem may be made tight.
  • one end of the valve stem is ground by the keen edge of the coiled spring mounted on the bottom of the cylinder.
  • the orifice is often clogged with the ground powder of the material of the valve stem.
  • the operation for depressing the spray head is unstabilized due to a comparatively short length of fitting between the spray head and the valve stem.
  • the spray container having a spray pump it is desirable that the optimum inital set condition given by the manufacturer is maintained over the period of use of the spray container, by avoiding the unintentional relative rotation between the valve stem and the spray head.
  • the present invention aims at providing a spray pump which can fix and hold the spray nozzle port of the spray head at the correct position.
  • an object of the invention to provide a spray pump in which the vertical upward and downward movement of the spray head is guided correctly in such a manner as to avoid any unintentional rotation of the spray head with respect to a stationary cap attached to the neck of the liquid container.
  • a spray pump comprising a fitting projection formed in one of the ceiling surface of the stationary cap and the opposing lower end surface of the spray head, and a fitting recess formed in the other of these surfaces, one of these fitting surfaces being provided with a rotation-preventing rib or the like protrusion while the other has a slit for guiding the protrusion, the fitting engagement between the spray head and the stationary cap being made beforehand when the spray head is fixed to the plunger.
  • Fig. 1 is a sectional side elevational view of a pump structure showing a spray head and a stationary cap.
  • the stationary cap 1 has a ceiling plate la and an annular peripheral wall lb suspending downwardly from the periphery of the ceiling plate la so as to form a downwardly opening fitting recess 2. Screw threads are formed in the inner peripheral surface of the recess 2 so that the stationary cap 1 can be freely screwed onto and out of the outer periphery of a neck portion of the spray container.
  • a pump cylinder 3 has a flange 3a which contacts at its upper surface with the lower surface of the ceiling plate la. The pump cylinder 3 is made to fit in the recess 2 to suspend downwardly therefrom.
  • the pump cylinder 3 accomodates a plunger 4 having a piston and a coiled spring supported by the bottom of the cylinder 3.
  • the cylinder 3 is provided with valves at portions thereof adjacent to the plunger and the suction pipe.
  • the upper end portion of the plunger 4 projects upwardly through the central bore lc of the ceiling plate la by a height which is determined in view of the necessity for the fitting to the spray head and the downward stroke.
  • An inner cylinder 5 and an outer cylinder 6 protrude from the ceiling plate la as a unit with the latter, concentrically with the central bore lc.
  • An inner annular recess 7 provided in the inner cylinder surrounds the plunger 4 protruding through the central bore lc so as to open upwardly with the bottom thereof constituted by the ceiling plate.
  • an outer annular recess 8 is formed between the inner cylinder 5 and the outer cylinder 6 so as to open upwardly with the bottom thereof constituted by the ceiling plate.
  • a reference numeral 9 designates a fitting surface formed on the outer periphery of the inner cylinder 5 and adapted to fit in the spray head 10. Ribs 11 of a prdetermined height is formed on the fitting surface 9 so as to extend in the axial direction.
  • Ribs 11 of a prdetermined height is formed on the fitting surface 9 so as to extend in the axial direction.
  • the described embodiment employs 3 (three) ribs 11 arranged at a constant circumferential pitch, it is possible to use only one rib 11.
  • Each rib 11 may have the form of a small projection.
  • the spray head 10 is provided therein with a discharge passage consisting of a vertical bore 12, a horizontal bore 13 and a nozzle 14 provided on the end of the horizontal bore 13.
  • the spray head 10 is further provided at its lower end with a fitting bore 15 of a rather large diameter adapted to fit around and receive the upper end of the plunger 4 so as to be fixed and connected to the plunger 4.
  • the fitting bore 15 is in communication with the vertical bore 12.
  • the spray head 10 is provided on the lower end thereof with a convexity or concavity complementary to the shape of the upper surface of the stationary cap 1. More specifically, the spray head is provided at its lower end with a downwardly opening recess 16 having an inside diameter ⁇ substantially equal to the outside diameter of the inner cylinder 5 on the stationary cap 1.
  • annular cylinder 17 for fitting in the outer peripheral recess 8 of the stationary cap 1 is formed on the outer periphery of the spray head.
  • the fitting recess 16 in the spray head has a diameter substantially equal to the outside diameter of the inner cylinder 5.
  • a fitting surface 18 for mating with the fitting surface 9 of the of the inner cylinder 5 is formed on the inner periphery of the fitting recess 16.
  • Axial guide slits 19 are formed to extend from the lower end of the fitting surface 18 to a prdetermined height so as to receive the ribs 11 formed in the inner cylinder 5.
  • the spray head 10 having the convexity and concavity has to fit to the complementary surface of the stationary cap 1 when the same is set on the plunger 4.
  • the connection between the plunger 4 and the spray head 10 are accomplished by aligning the ribs 11 on the stationary cap 1 and the guide slits 19 in the spray head 10.
  • the ribs 11 are retained by the side walls of the slits to prevent the spray head 10 from rotating to ensure that the initial optimum direction of the nozzle is maintained permanentally.
  • the ribs 11 provide a good guide for the vertical movement of the plunger so that the upward and downward stroking of the spray head 10 can be made in quite a stable manner. If the length of fit between the plunger 4 and the spray head 10 is short, the spray head may be declined when the same is pushed downward to impair the vertical depression of the plunger 4. However, in the spray head of the invention, the undesirable lateral oscillation and declining of the spray head are avoided because a very stiff connection is achieved by the fitting engagement with the stationary cap.
  • Fig. 3 shows another embodiment having a different construction for rotation prevention fitting between the spray head 10 and the stationary cap 1.
  • the fitting surface 9 is formed on the inner periphery of the inner cylinder 5 of the cap 1, and the guide slits 19 are formed in the fitting surface 9 to extend from the upper end to lower end of the cylinder.
  • the spray head 10 has a mounting cylinder 20 for mountng the plunger 4, and the fitting surface 19 is formed on the outer periphery of the cylinder 20.
  • the fitting surface 19 is provided with ribs or small projections which serve to prevent the rotation as in the case of the construction shown in Fig. 1.
  • the annular cylinder 17 on the spray head 10 may be omitted but, preferably, this cylinder 17 is formed from the view point of design or appearance of the spray head.
  • Fig. 5 shows still another embodiment having a different construction for rotation prevention fitting between the spray head 10 and the stationary cap 1.
  • the stationary cap 1 has the outer cylinder 6 the inner peripheral surfaceof which serving as the fitting surface 9 in which formed are the guide slits 19.
  • ribs 11 and other small protrusions are formed on the fitting surface 18 on the outer periphery of the annular cylinder 17 of the spray head 10.
  • a reference numeral 21 designates a suction pipe which extends downwardly from the lower end of the pump cylinder 3.
  • a fitting projection is formed in one of the opposing surfaces of the ceiling plate la of the stationary cap 1 and the spray head 10 while a cooperating fitting recess is formed in the other surface.
  • One of these fitting surfaces is provided with ribs or the like protrusions while the other is provided with slits.
  • the convexity and concavity formed in the fitting surfaces of the spray head and the plunger are effective to some extent in weakening the rotation prevention force to facilitate the work for setting the spray head and in guiding the spray head when the latter is reciprocally moved up and down, thereby to ensure a correct operation of the spray head.
