Definitions

  • the closure cap is formed with an outlet opening positioned for communication with the said'port.
  • CONTAINER WITII VENTING GASKET This invention relates to improvements in containers, and more particularly encompasses the inclusion in a generally conventional product container of a self venting and leakproof closure cap gasket or liner.
  • various liquid products are packaged in plastic containers having flexible walls, and equipped either with a conventional sealing type closure cap or with a closure cap of the type defining a discharge outlet such as a spout.
  • a sealing type of closure is employed, the product is normally dispensed by pouring after removing the closure cap.
  • the closure cap is provided with a discharge outlet, the product is generally dispensed by manually squeezing the container as many times in succession as may be necessary to expel the desired amount of the product.
  • the present invention contemplates the inclusion in the container of a combination gasket and diaphragm check valve secured in place over the usual filling and dispensing opening of the container by means of the usual removable container closure, thus to function as a gasket for preventing product leakage under all conditions between the container and closure, while freely admitting air from the atmosphere whenever the atmospheric pressure appreciably exceeds the pressure within the container.
  • the invention is by no means restricted to use with such containers, but may be used to advantage in connection with rigid-walled containers.
  • a unitary gasket and check valve member the gasket portion of which is clamped between the closure and the neck of the container in sealing relation around the filling and dispensing opening.
  • the member includes a resiliently flexible annular diaphragm or diaphragm portion which is supported over said opening so that its inner periphery defines a valve port communicating through said opening with the container interior. Normally, its own resiliency and the fluid pressure within the container maintain the diaphragm in sealing engagement with a valve seat supported within the container and preferably defined by the closure.
  • Air from the atmosphere is admitted between the closure and the diaphragm to act on the diaphragm in opposition to the pressure exerted against the under face of the diaphragm from within the container. ACCordingly, any material decrease of the container internal pressure below atmospheric will unseat the diaphragm to permit atmospheric air to enter the container until pressures on opposite sides of the diaphragm are substantially equalized.
  • the container closure is of a conventional type having an internally threaded skirt by which it is secured on the container neck in a manner such that atmospheric air may flow upwardly between the skirt and neck.
  • air is admitted between the closure and the diaphragm through a groove extending across the upper face of the gasket portion of said member.
  • valve seat of the closure, the inner end of the outlet, and the valve port communicate with the outlet to permit discharge of the product on each squeeze stroke, while unseating of the diaphragm between squeeze strokes permits atmospheric air to be drawn into the container through the valve port without having to pass through the product outlet.
  • FIG. I is a vertical section through the upper end portion of a typical container to which the invention is applied:
  • FIG. 2 is a detail perspective view of the combination gasket and diaphragm valve employed in the container of FIG. 1;
  • FIG. 3 is a cross section on the line 3-3 of FIG. 2;
  • FIG. 4 is a view similar to FIG. 1, of a modified form of the invention, as incorporated in a squeeze bottle type of dispensing container;
  • FIG. 5 is a detail perspective view of the combination gasket and diaphragm valve employed in the container of FIG. 4;
  • FIG. 6 is a cross section on the line 66 of FIG. 5.
  • FIG. 1 the upper portion of a container, here exemplified by a conventional threaded neck 12, to which the internally threaded skirt [4 of a closure cap 18 is operatively applied to secure the closure cap on'the container.
  • the closure cap is provided with a top wall portion 18 overlying the upper end ofthe container neck 12.
  • a diaphragm valve 20 has its outer marginal portion 22 clamped between the top wall 18 of the closure cap and the upper end of the container neck 12, to function as a gasket in sealing engagement with the container neck around the usual filling and dispensing opening 24.
  • the lower surface of the gasket portion 22 in this embodiment is provided with one or more annular sealing ribs 26, and the entire diaphragm valve 20 is formed of a resiliently flexible material, such as polyethylene or other suitable plastic, or of a natural or artificial rubber. If desired, the sealing ribs 26 may be received in suitable annular grooves formed in the end of the container neck 12, as disclosed, for instance, in the US. Pat. to Corsette No. 3,l79,306.
  • the diaphragm valve 20 extends over the opening 24 of the bottle neck and its underside is exposed to fluid pressure within the container, while the upper surface thereof is exposed to atmospheric pressure in the manner hereinafter described.
  • the diaphragm valve 20 is formed with a centrally located valve port 30 which communicates with the interior of the container 10 through the filling and dispensing opening 24.
  • the diaphragm valve 20 prior to application to the container is so formed that the outer marginal area, including the gasket portion 22 thereof is substantially flat, while the central area 28 thereof around the port 30 is of domed shape projecting substantially above the surface of the surrounding gasket portion 22.
  • the lower surface of the cap top wall where it engages and seals against the inner periphery of the diaphragm valve 20 around the port 30, functions as a stationary valve seat, carried by the container 10. Because of the deforming action of the top wall 18 on the resiliently deformable diaphragm valve 20, it will be apparent that the raised or domed central area of the diaphragm valve is resiliently biased upwardly into sealing engagement with the valve seat defined by the under face of the cap top wall 18.
  • this air chamber 34 communicates with the atmosphere, so that atmospheric pressure will at all times be exerted on the upper surface of the diaphragm valve 20 in opposition to the fluid pressure existing within the container and acting against the under surface of the diaphragm valve. Obviously, such internal pressure will supplement the biasing action of the diaphragm valve in maintaining the sealing engagement between the diaphragm valve and the seat 18 on the closure cap.
  • one par ticularly advantageous way which renders the invention capable of use with a conventional threaded container cap consists in providing one or more grooves or passages 36 which traverse the upper surface of the diaphragm valve extending inwardly from its outer periphery or margin, preferably to the domed area 28, or in any event sufficiently far so as to communicate with the air space 34 when the member 20 is in use as shown in FIG. 1.
  • the inner surface of the cap skirt 14 above the threaded portions thereof has a slight clearance, both with the outer periphery of the member 20 and with the bottle neck 12, and, obviously, this clearance space communicates with the atmosphere through the helical space between the interengaged threads of the skirt l4 and container neck 12.
  • a retainer 38 for holding the member 20 within the container cap or closure 16 prior to its application to the container 10
  • such retainer 38 consists of a plurality of relatively spaced projections, or is otherwise of a discontinuous nature so as to permit the free passage of atmospheric air upwardly between the cap skirt I4 and container neck 12 and into the outer ends of the grooves 36 in the gasket portion 22.
  • the under surface of the top wall 18 of the cap may be suitably recessed for sealing engagement with a comparatively increased area of the domed portion 28 of the diaphragm valve around the air inlet port 30, or, for instance, a suitably tapered sealing pin (not shown) might be carried by the undersurface of the top wall 18 for sealing reception in the air inlet port 30 of the diaphragm.
  • the port 30 will remain closed.
  • the function of the diaphragm valve 20 is similar to that of a check valve in that it permits only an inflow through the port 30 and acts at all times to prevent an outflow through such port.
  • any increased pressure within the container 10 will serve only to seat the diaphragm more securely against the seat or seat portion 18 of the cap.
  • the combined gasket and check valve of the invention is adapted for use with a generally conventional liquid container and dispenser of the flexible wall or squeeze bottle"type to serve the same functions as in the immediately preceding embodiment and, in addition, to provide an increased air inlet capacity for quicker recovery of the container after each squeeze or deformation thereof. This is especially a factor when repeated squeeze strokes are required in fairly close succession and where the product being dispensed is of a comparatively thick or viscous nature, such as to substantially impede the entry of air through the dispensing opening.
  • FIG. 4 there is shown fragmentarily the upper end portion of a conventional flexible wall plastic squeeze bottle 10a, provided with an externally threaded neck 12a defining a filling and dispensing opening 240, and having the depending threaded skirt 14a of a container closure cap 16a applied thereto substantially as in the preceding embodiment.
  • the outer marginal portion of the cap top wall 18a overlies the upper end of the container neck 12a to clamp the combined unitary gasket and diaphragm valve 20a against the container neck in sealing relation thereto, for which purpose the gasket portion .220 may be equipped with sealing rings or ribs 260! as before.
  • this embodiment is similar to the preceding embodiment. However, it differs therefrom in that the closure cap 16a is formed to define a centrally located product outlet 310, preferably through a discharge spout 40a which, in the present instance, is shown as having a closed tip or dispensing end which is adapted to be cut off in order to permit dispensing therethrough of the container contents.
  • the valving portion 28a of the diaphragm valve in this embodiment is defined by an upwardly projecting portion of the member 200: which tapers upwardly in thickness to its upper peripheral edge which defines the air inlet port 30a.
  • the lower end portion of the spout 40a is formed with a preferably tapered recess, the inner surface of which defines the valve seat 32a which concentrically surrounds and sealingly engages the inner peripheral portion of the diaphragm valve 20a around the port 3011!.
  • the diaphragm 20a is depressed somewhat downwardly by such engagement, thereby slightly deforming it as shown, so that its valving portion 28a normally is resiliently biased upwardly into sealing engagement with the seat 32a.
  • the internal pressure of the container 10a will be exerted against the. diaphragm valve 20a on the underside thereof to urge its inner periphery around the port 3001 against the seat 32a.
  • the seat portion 32a of the closure cap diverges downwardly at a somewhat greater angle than does the exterior surface of the conical valving portion 280:, so as to define between the two an air chamber 340 which chamber communicates outwardly with the atmosphere through the radial groove or grooves 360, in the upper surface of the diaphragm portion 22a, thence downwardly to the atmosphere between the threaded skirt 14a, of the closure cap and the threaded container neck 12a, just as in the preceding embodiment.
  • the combined gasket and check valve 20a will serve the same functions as the check valve 20 of the preceding embodiment. That is, so long as the pressure within the container a substantially equals or exceeds the external atmospheric pressure, the inner periphery of the diaphragm valving portion 28a around the air inlet port 300 will be pressed upwardly into sealing engagement with the valve seat 32a, both by the resilient biasing action resulting from slight downward displacement of the diaphragm a, and also by the internal container pressure.
  • the closed upper end of the spout 40a may be removed as by being cut away in conventional manner, following which the container is partially inverted and subjected to as many squeezes or squeeze strokes as are necessary to expel] the desired amount of its content through the port 30a and spout 40a.
  • a flexible walled container having an externally threaded neck defining a filling and dispensing opening, and a removable closure comprising an internally threaded skirt operatively disposed on said neck, said closure including a top wall overlying the end of said neck, in combination with:
  • annular flexible diaphragm having its outer periphery clamped between said closure top wall and said container neck, said closure defining a product outlet;
  • said diaphragm having an inner periphery communicating with said product outlet and defining an air inlet and product discharge port for said container;
