Abstract

A combination gasket and venting member including a gasket portion clamped between the closure cap and the neck of a container in sealing engagement with the neck and further including a flexible annular diaphragm encircled by the gasket portion. The diaphragm extends over the filling and dispensing opening of the container neck and defines a centrally located valve port communicating with such opening and adapted to seat against the underside of the closure cap. A groove extending across the upper face of the gasket portion from the outer periphery of the latter, where it communicates with the atmosphere, admits atmospheric air above the diaphragm to depress the central portion thereof away from the closure cap when atmospheric pressure exceeds the pressure within the container, thus to admit atmospheric air through the port into the container. In one embodiment the closure cap is formed with an outlet opening positioned for communication with the said port.

The diaphragm extends over the filling and dispensing opening of the container neck and defines a centrally located valve port communicating with such opening 7 and adapted to seat against the underside of the closure cap. A

groove extending across the upper face of the gasket portion Q from theouter periphery of the latter, where it communicates with the atmosphere, admits atmospheric air above the 'diaphragm'to depress the central portion thereof away from the closure cap when atmospheric pressure exceeds the pressure within the container, thus to admit atmospheric air through the port into the container. In one embodiment 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.

As is well known, 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. Where a sealing type of closure is employed, the product is normally dispensed by pouring after removing the closure cap. Where 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.

When, for any reason, the pressure within such a container drops appreciably below the ambient atmospheric pressure, as for instance because of permeation loss through the container walls or because of temperature changes, there results a partial collapse and distortion of the container. This in turn, tends to convey a poor product image to prospective purchasers of the product.

Moreover, where such containers are employed as squeeze bottles, as above described, and particularly where the product therein is of a thick or viscous nature, such product will tend to clog the dispensing outlet and interfere with the passage of air into the container, as is necessary to permit reexpansion of the container after each squeeze stroke. This delay in recovery of the container between strokes undesirably retards the dispensing rate.

Manifestly, therefore, it is desirable to improve such containers by providing for the maintenance of near atmospheric pressure in them. Where the containers are of the squeeze bottle type, it is further desirable to provide for the rapid admission of air into them between squeeze strokes, notwithstanding partial or complete clogging of their dispensing outlets by the products being dispensed. It is nevertheless important to prevent outflow of the product through the air inflow path.

It is further desirable to achieve these ends simply, economically, and without material modifications of existing types of containers.

With these considerations in mind, 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.

Although realizing its greatest usefulness in connection with flexible walled containers, the invention is by no means restricted to use with such containers, but may be used to advantage in connection with rigid-walled containers.

In accordance with the invention there is provided 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.

In a preferred form, 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. Such air is admitted between the closure and the diaphragm through a groove extending across the upper face of the gasket portion of said member.

When the invention is incorporated in a squeeze bottle having a product outlet through its closure, the 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.

In the accompanying drawings, showing specific embodiments of the invention by way of example:

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; and

FIG. 6 is a cross section on the line 66 of FIG. 5.

Referring now in detail to the accompanying drawings, and,

' first, considering the embodiment of the invention illustrated in FIGS 1, 2 and 3, there is shown in 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. To improve the effectiveness of such seal, 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.

lnwardly of the gasket portion 22 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. As will be seen by reference to FIG. 2, 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. Thus when the member 20 is applied to the container, in the manner illustrated in FIG. I, the downward pressure of the top wall 18 of the closure cap 16 is concentrated against the inner peripheral portion 28 of the diaphragm around the port 30, to effect a seal against and to depress the diaphragm. Thus 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.

Further, it will be apparent that because of the domed configuration of the diaphragm portion 28, only the inner peripheral area thereof around the port 30 is engaged by the top wall 18 of the cap, to function as a valving portion in cooperation with the top wall, and in the operative position of the parts shown in FIG. 1, the cap and the diaphragm 20 are mutually conformed to define between them an annular air chamber 34 above the diaphragm, Normally the air chamber 34 is sealed off from the port 30 by the sealing engagement between the diaphragm and its seat portion 18 of the cap.

In accordance with the invention, 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.

While the communication between the air chamber 34 and the atmosphere might be achieved in various ways, 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.

In accordance with conventional pract e, 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. Where the cap is provided with 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.

It will be apparent that for greater sealing efficiency such as might be desired for certain applications, 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 use of a combined gasket and diaphragm valve such as above described, will be found particularly advantageous where the container 10 in a generally conventional flexible walled plastic bottle such as is commonly used for detergents and other chemicals, and in which the container walls tend to collapse inwardly because of reduced internal pressure such as may result from permeation loss through the container side walls or other causes. In the event the pressure within the container, for any reason, falls substantially below the atmospheric pressure, atmospheric air passes upwardly between the threaded portions of the cap skin 14 and container neck 12, between the retainer bead segments or projections 38, and thence through the grooves 36 to the air chamber 34 above the diaphragm 28. Any material excess of atmospheric pressure over the internal pressure of the container will permit the air in chamber 34 to depress the central portion of the diaphragm 20, thereby unseating same from the valve seat defined by the under-surface of the cap top wall 18 and thereby permitting the air from the space 34 to flow into the container through the air inlet port 30 until the pressure within the container is nearly equal to atmospheric pressure, at which time the resilient biasing action of the diaphragm 28 will again seat it against the undersurface of the cap 'top wall 18.

It will be apparent that where the fluid pressure within the container 10 substantially equals or exceeds that of the atmosphere, the port 30 will remain closed. In other words, 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. Manifestly, 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.

In the modified form of the invention, shown in FIGS. 4, 5 and 6, 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.

Thus, in 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.

As thus described, 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!. As in the preceding embodiment, 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. Normally prior to removal or cutting away of the closed end of spout 4001, 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.

As will be apparent in FIG. 4, 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.

During shipping and storage of liquid filled containers equipped with the invention as shown in FIGS. 4, 5 and 6, 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. g

In the event the internal pressure of the container [00 becomes substantially less than that ,of the atmosphere, the atmospheric pressure within the air chamber 340 above the diaphragm valve 20a will depress the same to move the valving portion 280 away from the seat 32a so that atmospheric air may pass between the seat 32a and the valving portion 280, thence through the opening or port 30a into the container. By thus venting the container interior to the atmosphere, any partial collapsing or deformation of the container, due to reduction of pressure therein from any cause, will be prevented. 0n the other hand, the contents of the container will be sealed against escape regardless of the internal pressure within the container.

In order to place the container in use for dispensing purposes, 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.

in the usual dispensing container of tks type which is not equipped with the combined gasket and check valve of the instant invention, it is necessary that following each squeeze stroke, sufficient air must enter the container through its spout in order to permit reexpansion of the container before a further squeeze stroke can be commenced. Where the product being dispensed is of a comparably thick or viscous nature such as to impede the inflow of air through the spout, the frequency of the squeeze strokes is necessarily considerably decreased.

It will be apparent, however, that by the employment of the structure shown in FIG. 4, after each squeeze stroke, air may be permitted freely to enter the container between the gasket diaphragm or valve portion 28a and its seat 32a and thence through the port 30a, independently of any liquid retained in the spout 40a, thus making possible the discharge of product from the container at an increased rate.
