Definitions

  • the valve mechanism includes a stem in guiding but spaced relationship to the dome-shaped portion of the cap thereby forming a gap or clearance through which air is readily drawn to rapid-ly recuperate the earlier distortion of the manually squeezed container walls. This rapid recuperation is achieved in the absence of detrimental effects which might otherwise preclude a perfect admixture of air and liquid during the dispensing or compression portion of the dispensing operation.
  • An added advantage of the dispensing cap is the particular -bell-shaped configuration of a valve of the valve mechanism which is rapidly moved in the forward direction when the container wall is squeezed and is additionally guided by the atomizing mechanism in both the fo-rward and backward directions of travel thereof. This guiding of the valve assures complete close-off of the cap during the compression of the container and prevents the valve from misseating in either the closed or open position thereof.
  • FIG. 1 is an axial sectional view through a novel dispensing cap of this invention, and illust-rates a bell-shaped valve which is guided in its reciprocal movement and is limited in its downward movement by an atomizing mechanism of the dispensing cap.
  • FIG. 2 is an axial sectional view through another dispensing cap of the invention, and discloses a bell-shaped valve which includes an axial dispensing orifice as compared to a generally radial dispensing orifice of the dispensing cap of FIG. l.
  • the dispensing or atomizing cap of FIG. 1 includes a peripheral skirt 1 provided with means (not shown), such rice as screw threads or lugs, for securing the cap to a dispensing or atomizing container (also not shown) of the type having a body wall constructed from collapsible material, such as copolymeric plastic or rubber.
  • the cap includes a dome-shaped portion 2 which is provided with an internal annular valve seat or surface 3 against which is adapted to seat a valve 5 having a stem 6.
  • the stem 6 projects axially upwardly from a bell-shaped conical portion (unnumbered) of the valve 5, and is reciprocally received in an axial bore or aperture 4 of the 'dome-shaped portion 2.
  • the aperture 4 and the stem 6 are preferably circular in transverse section and an appreciable annular gap or clearance is provided therebetween to facilitate the recuperation of the dispensing container as will be more apparent hereinafter.
  • the stem 6 and aperture 4 can be relatively close litting but either the stem or the surface defining the bore can be provided with a relatively large axial groove or slot.
  • the appreciable clearance permits air to quickly enter the collapsed container and effect the recovery of the collapsible wall thereof to its normally uncollapsed position.
  • the admixture of liquid and air takes place through a suction tube 10 and channels ⁇ or bores 9 formed in an internally housed atomizing mechanism or nozzle 8 of the cap.
  • the atomizing mechanism 8 is press-lit or otherwise secured in the cap at a position which limits the downward movement of the valve 5 (both FIGS. l and 2) and thus accurately limits the 4size of the valve aperture to assure an eicient atomization of the liquid-air admixture.
  • valve 5 of each cap does not interfere with the .intake of air through the suction tube 10, which is not true of conventional atomizers, since the dispensing orifices 7 allow unobstructed access of air to the suction tubes 10 independent of the air channels or bores 9 in the atomizing mechanism 8.
  • the weight of the valve 5 augments the recovery of the container toward its normal uncompressed condition.
  • valve 5 can be increased by positioning a silicone or similar elastic material gasket therebetween.
  • the atomizing mechanism 8 can be provided with additional channels or bo-res 9.
  • the dispensing orifice 7 can be positioned midway between its illustrated position and the orifice 4.
  • the valve 5 would include a bore which would be in axial alignment with the noted displaced orifice 7 when the valve 5 is in the position i-llustrated in FIG. l of the drawing.
  • a dispensing cap particularly adapted for -use with a collapsible walled container comprising a hollow generally dome-shaped portion having an axial bore, a valve, means mounting said valve for reciprocal movement between dispensing and nondispensing positions, 1an atomzing mechanism housed within said cap, a chamber between said atomizing mechanism and said dome-shaped portion, bore means in :said atomizing mechanism for placing said chamber in communication with a container to which the cap is adapted to be secured, and said domeshaped portion including a valve seat for limiting the movement of said valve toward ⁇ dispensing position of said valve, and said atomizing mechanism including means for limiting the movement of said valve toward nondispensing position of said valve, said valve being of a bell-shaped conguration, and said atomizing mechanism including a suction tube in underlying relationship to said bell-shaped valve.
  • valve includes an axial stem, said stem being reciprocally mounted in said bore, and means provided for forming an appreciable clearance between said stem and said bore.
  • suction tube is disposed generally internally of said bell-shaped valve to guide the yreciprocal movement thereof toward at least the nondispensing position of said valve.
  • valve includes an axial stem, said dome-shaped portion being provided with an axial bore, said stem being reciprocally mounted in said bore, and there being axial channel means between said bore and said stem for admitting air into said chamber.
  • valve includes an axial stern, said stem being reciprocally mounted in said axial bore, clearance means between said stem and said axial bore, said valve including a dispensing orifice disposed generally axially thereof, and said suction tube defining said means for limiting said valve in the nondispensing position thereof.
  • valve includes a generally downwardly opening concave bell-shaped portion, and said bell-shaped portion being in generally externally telescopic relationship to said suction tube in the nondispensing position of said valve.
