  • Thepump' D includes a conventional pump cylinder 20depending into-the containerthroughits filling and dispensing opening-l3 and in spaced relatio'n tothe surrounding neck structure.
  • Extending downward frornfthe lower end of the pump'barrel 2 O is a usual dip tube 22i of fwhich'the lowerend (not-shownlwill normally bedispo'sedjust above the bottom of thec'ontaine'r' so-that theliquid product may be drawn upward through t he tube'22 and 'cylinder2 0 on each operative stroke of the pumpplunger 2am be expelled throughthe conventional discharge thead 24in well-known manner.
  • The'upper'end portion of the plunger 23 preferably is covered-and protectedby a removable overca p 28, the downward opening lower end of which is snap fitted onto an enlarged collar 30 affixed to a radial enlargement 32 at the cap is clamped between the collar 30 and the usual supporting flange 34 affixed to the pump cylinder 20 near its upper end.
  • the pump structure is thus supported by the closure cap so that the cap and pump may be applied as aunit to the container in well-known manner.
  • the pump cylinder is a formed with one or more air vents such as 36 extending through its sidewall within the container, normally at a location above the pump piston (not shown).
  • Thisvent 36 normally places the interior of the container in communication with the atmosphere, through the upper end of the pump cylinder and the usual clearance space between the collar 30 and the plunger 23 which reciprocates therethrough.
  • the function of the vent 36 is to permit air from the atmosphere to enter the container to replace the product as the latter is withdrawn by operation of the dispensing pump, as well as to provide a means for returning to the container at least a portion of any product that might have become trapped within the cylinder above the pump piston.
  • a combined gasket and diaphragm valve 38 which functions independently of the dispensing unit D to admit atmospheric air into the container whenever the fluid pressure within the container drops appreciably below atmospheric pressure.
  • the said diaphragm valve and gasket 38 is of annular shape such that when assembled with the other parts, its outer peripheral portion 38a is compressed between the upper end of the container neck 12 and the supporting flange 34 of the pump cylinder. Both the flange 34 and the gasket portion 38a are clamped between the end of the container neck and the closure cap.
  • the gasket portion 38a is provided with suitably arranged concentric sealing ribs 40 on its undersurface for cooperation with the container neck in the usual manner.
  • the upper end of the container neck may be provided with concentric grooves (not shown) for cooperative reception of these sealing ribs in the manner such as disclosed, for instance, in the [1.5. Pat. No. 3,l79',306 to Corsette. I
  • the'centr'al area or valve portion 38b of the member 38 is of downward converging frustoconical configurationand its walls are of downward tapering thickness toward its converging-end so as to increase its flexibility.
  • the valving portion 38b has its'inner peripheral end 42 encircling the pump valve and normally'in snug. radial sealing engagement therewith.
  • Such peripheral edge 42 defines a valve port preferably of slightly smaller diameter than the cooperating 42 of the valving portion in this sures within the container 10 will act on 'the-undersurface of the diaphragm valve and gasket 38 to urge-its downward convergent valving portion 38b radially into sealing relation with the pump cylinder 20 and to isolate the vent 36 of, the pump cylinder from the container interior, the peripheral lower edge instance being disposed below the vent 36.
  • the valving portion 38b and the pump cylinder 20 jointly define between them an air chamber 41 which communicates with the atmosphere as hereinafter described so that the upper surface of the valving portion 38b is exposed to atmospheric pressures in opposition to the internal container pressure operating against the undersurface of the valving portion 38b.
  • the air space or chamber 41 communicates outwardly between the supporting flange 34 and the gasket portion 38a of the gasket 38 through one or more radial grooves 44 formed in the upper surface of the gasket portion 38a.
  • the outer end of each such groove or passage 44 communicates with the radial space 46 between the closure cap skirt l4 and the externally threaded neck of the container to com municate with the atmosphere through the clearance space between the coacting threads of the neck 12 and skirt 14.
  • the diaphragm valving portion 38b permits entry of air from the atmosphere into the container at any time that atmospheric pressure substantially exceeds the internal pressure of the container.
  • This function is entirely independent of the pump and its vent 36 and may occur during storage and shipping. in addition, such venting function may supplement the venting action of the pump cylinder vent 36 during operation of the pump to admit air into the container for product replacement purposes.
  • the disposition of the member 38 with respect to the vent 36 modifies the action of the vent to permit only an influx of air through the vent into the container while barring positively the outflow of any fluid from the container through the vent as well as through the groove or passage 44.
  • the member 38 functions to permit operation of the pump for dispensing purposes even though the container may be tilted to a near horizontal position in which the product, except for the presence of the member 38, would cover the vent 36 and tend to escape therethrough. Moreover, the fact that the member 38 isolates the vent 36 at all times from the product, ensures against the plugging of the vent by the product.
  • the construction of the container and the dispensing pump are identical in all respects with the corresponding elements of the preferred embodiment, but the combined diaphragm valve and gasket member 380. has been somewhat modified to cooperate in slightly different manner with the pump.
  • the gasket portion 380a is similar in structure and cooperates with the other elements in the same manner as earlier described, but that the diaphragm valve portion 380b is so arranged that its convergent lower end edge 420 engages and encircles the pump cylinder at a location above the vent 36.
  • the member 380 thus does not isolate the vent 36 from the product within the container as in the preferred embodiment and the vent 36 is permitted to achieve its usual functions in well-known manner -without interference by the member 380.
  • the member 380 in addition to functioning as a gasket at its outer portion 3800, has its valving portion380b arranged and cooperating with the pump structure to admit air into the container quite independently of the pump when the atmospheric pressure exceeds the fluid pressure within the container. Thus, air will be admitted into the container under suitable conditions even though the communication between the vent 36 and the atmosphere is disrupted in conventional manner during shipping and storage of the' container.
  • the valving portion 38% will cooperate with the pump in a manner to supplement or even to replace the action of the vent in admitting atmospheric air into the container for replacement of the withdrawn product.
  • the valving portion 380b cooperates with an upwardly and outwardly flaring generally conical surface portion 45 of the pump cylinder rather than the cylindrical exterior surface of the pump cylinder as in the preceding embodiment, but that the mode of cooperation between these elements remains essentially unchanged.
  • This embodiment finds particular utility when employing a pump of the type in which the vent passages are sealed by locking the plunger in its fully depressed position during shipping and storage.
  • atmospheric air will be admitted to the container independently of the vent, to prevent container deformation by external pressure, despite the sealing of the vent passages.
  • a dispensing pump supported by the container has its pump cylinder extending into the container through the dispensing opening thereof, in spaced relation to the container wall which defines said opening, the combination with said container of an annular diaphragm valve of resiliently flexible material snugly receiving said cylinder in sealing engagement therewith at a location below said vent.
  • valve encircles and seats radially against the cylindrical exterior surface of said pump cylinder.
  • valve is formed with a groove extending across its upper surface from said air chamber to its outer periphery to place said chamber in communication with the atmosphere.
  • valve secured to the container in sealing relation around said opening, said valve defining a circular valve port which normally snugly receives said cylinder in sealing relation therewith, the lower surface of said valve being exposed to the internal fluid pressure of the container and the upper surface of said valve being exposed to atmospheric pressure.
  • valve is of elastomeric material and includes a valving portion immediately surrounding said port and diverging upward therefrom within the container opening.
  • said cylinder is 7 provided with an air vent through its sidewall to establish communication between its interior and said opening, said valve end 0 said nee a reciprocating pump having a pump cylinder extending through said closure and said opening into the container interior in spaced relation to the neck, the pump having a plunger disposed for reciprocation in said cylinder through its upper exterior end, the combination therewith 0 an annular diaphragm valve having a portion of flexible elastomeric material surrounding said cylinder with the inner periphery of said valve normally snugly encircling and sealing against said cylinder within the said opening, said cylinder having a radial supporting flange near is upper end between said closure and the container neck, the outer peripheral portion of said valve being disposed between said supporting flange and the container neck in sealing engagement with the latter, said cylinder and valve defining an air chamber within the container opening between said flange and the valve, and means. foradmitting air from the atmosphere into said chamber.
