  • the piston stem also has a small-diameter bore 62 which communicates with the bore 18 of the hollow boss of the depress button.
  • the piston member 54 further comprises a pair of .axia'lly spaced annular or ring-like piston elements 64 and 66, such elements being preferably of conical configuration with square-section cylinder-engaging peripheral portions 68 and 70 respectively.
  • the piston element 64 is connected with the piston element 66 by an intermediate shank portion 72, as shown.
  • the piston member 54 is hollow, that is, it has a through bore 74 in which there is disposed a discharge valve stem 76 carrying a valve enlargement 78 which is cooperable with the upper extremity 80 of the resilient shank 58 of the piston element 54. Clearance exists between the valve stem 76 and the walls of the bore 74 of the piston element, as shown.
  • valve stem 76 has a D-shaped enlargement 82 which is snugly seated in a shouldered portion 84 of the cylinder structure, being maintained in place by :a helical compression spring 86 which also bears against the shank portion 72 of the piston member 54.
  • the spring 86 not only maintains the valve stem 76 and valve enlargement 78 in a lowermost position at all times in the cylinder 34, as shown, but also continually yieldably urges upward the piston member 54 as well as the piston shank 22 and the depress button 14.
  • the compression spring 86 may be advantageously fabricated of stainless steel or equivalent non-corrosive metal.
  • a positive-action valve controlled venting is eifected, by which air is permitted to enter the cont ainer 10 from the exterior of the atomizer in order to replace the liquid which is being discharged.
  • venting action involves the vent hole 56 in the side of the cylinder 34, as well as the second piston element 66, 70.
  • vent hole 56 will now have communication with the exterior atmosphere, by virtue of the looseness of the fit between the stem portion 32 and interior of the cylinder 34, as well as the looseness of the fit between the stem portion 22 and the central opening 24 of the mounting cup 26. Atmospheric air may enter past such loose fitting parts, into the upper portion of the cylinder 34 and thence outward through the vent hole 56 to the interior of the container 10. It will be observed that the venting is effected by a positive valving action, involving the piston element 66, 70 and the cooperable port-ions of the cylinder 34, including the vent hole 56 in the wall of the cylinder.
  • the piston member 54 will assume the raised position illustrated in FIG. 2.
  • the piston element 66, 70 will now be disposed at a level above the vent hole 56, thereby effectively blocking the contents of the container 10 and preventing any liquid from leaking or seeping past the loose-fitting stem parts 22, 32.
  • the discharge control valve 78 will close the upper portion of the bore 74 of the piston member 54, whereby no egress of liquid from the interior of the piston 34 will be possible. In consequence, the container 10 is effectively sealed at all times that the piston assemblage is in the raised position shown in FIG. 2.
  • FIGS. 5, 6 and 7. Another embodiment of the invention is illustrated in FIGS. 5, 6 and 7.
  • the operation of this embodiment is similar to that of the previously described embodiment, except that in place of the two axiallyspaced piston elements 68, 70 shown in FIGS. 2 and 3, but a single annular piston element is provided, having an apprec-iable axial length and functioning not only to control the ingress of air to the container but also as the pressureproducing means which eirects the discharge of the container contents when the operating button is depressed.
  • the embodiment of FIGS. 5-7 employs a threaded screw cap, as distinguished from the crimped mounting cup of FIGS. 13.
  • the container 19 has a threaded neck portion 92 to which there is applied an internally threaded cap 94 having a sealing gasket 96.
  • the atomizer pump comprises a cylinder member 98 having at its upper end an outturned flange 100 which is disposed between the gasket 96 and the top wall 102 of the cap 94.
  • the cylinder member 98 In its side wall, the cylinder member 98 has a vent or air-ingress opening 104 which is normally closed by an annular piston element 106 of appreciable axial length.
  • the piston element 106 has a conical or tapered portion 108 joined to a hollow shank portion 110 whichlatter is carried in the lower end 112 of the plunger shank 114.
  • the manually engageable operating button 116 is carried, such button having the usual discharge passage 118 and spray head 120.
  • the passage 118 communicates with the bore 122 .of the shank 114,-and discharge of liquid through the bore 122 is controlled by a valve head or enlargement 124 carried on a central stem 126 whose lower end has a notched flange 128 maintained in engagement with a shoulder 130 of the cylinder memher by a helical compression spring 132.
  • a ball check valve 134 is carried in a conical seat 136 at the lower portion of the cylinder member 98, and a dip or siphon tube 138 is frictionally fitted in the hollow lower portion of reduced diameter 140 of the cylinder member.
  • the upper extremity of the shank 110 of the piston element constitutes a valve seat for the valve head or enlargement 124 carried by the central stem 126, and in consequence for the position of the parts shown in FIG. 5 the passage 122 is normally closed.
  • the button 116 is depressed or shifted downward, the seat in the shank 110 will leave the valve enlargement 124, opening the passage 122.
  • the action of the piston element 106 in reducing the effective volume in the cylinder 98 will force the liquid contained therein upward through the bore 122 and discharge passage 118, to be sprayed from the orifice member 120.
  • the piston element 106, 108, 110 is made of resilient rubber or rubber-like material, and for the raised position of the plunger assemblage it effectively closes the side opening 104 and prevents leakage of the contents of the container 90. Also, the piston assemblage is extremely effective in its action, tending to expand as the plunger assembly is shifted downward, thereby to etiectively increase the pressure within the lower portion of the cylinder and force the liquid contents thereof upward through the central bore 122 of the plunger shank 114.
  • the appreciable axial length of the portion 106 of the piston element provides for an etfective closing of the side opening 104, as well as preventing leakage of liquid between the piston element and the inner walls of the cylinder when the plunger is shifted downward.
  • the fabrication of the piston member 106, 108, 110 may be easily carried out, in simple mold equipment whereby there is effected an economy in the manufacture of this piece.
