DEVICE FOR DISPENSING AERATED PRODUCTS Filed Aug. 24, 1959 IN V EN TOR.

%.,M M444 pm.wi

nite This invention pertains to devices for dispensing aerated products from pressurized containers and more particularly to an improved valve construction provided with a closure guard for maintaining releasable sealing engagement between the valve plug and the seat.

Heretofore such dispensing devices for shaving cream, toothpaste, or whipped cream and the like have been susceptible to accidental dislodgment of the nozzle, or adjutage, and have included various mechanisms for maintaining the adjutage securely positioned through a container Wall or lid. Particular elements in addition to a basic assembly comprising a cap, an adjutage, a resilient plug and a mounting cup have been required, thus complicating or increasing the diificulty of putting such an assembly together. Even recent devices, when fabricated from flexible materials such as rubber and pliable plastics strong enough to secure the adjutage in position on the container without additional parts have shown that the adjutage or the surrounding resilient plug is frequently broken or cracked unless the device is painstakingly assembled.

It is therefore one object of this invention to provide an improved valve construction in which an adjutage may be securely maintained in position on a pressurized container.

Another object of this invention is to provide an improved valve construction in which an adjutage may be mounted on a pressurized container in secure fluid-sealing engagement using a minimum number of parts.

Yet another object of this invention is to provide an improved valve construction which may be simply assembled without danger of adjutage or resilient plug breakage and which guards against accidental adjutage dislodgment after assembly.

A further object of this invention is to provide an improvide valve construction in which a readily flexible resilient member and mounting cup cooperatively engage and securely aflix an adjutage on a pressurized container.

A still further object of this invention is to provide an improved valve construction in which a series of sealing blade members within a sleeve assist in securing an adjutage on a pressurized container and also facilitate pivotal operation of the adjutage.

Other objects and advantages wil1 become more apparent from the following detailed description.

According to one embodiment of this invention, there is provided a device for dispensing aerated products comprising a resilient sleeve having a valve seat at one end, an adjutage positioned through the sleeve, shoulder means on the adjutage wedged Within the sleeve, and a valve plug adjacent one end of the adjutage in releasable sealin'g engagement with the valve seat.

The details of one embodiment will be clear from the following description taken in conjunction with the accompanying drawings in which: 7

FIGURE 1 is an elevational view of a container in which the dispensing device of this invention is incorporated;

, FIG. 2 is an enlarged sectional view of a dispensing device illustrating one embodiment of this invention;

FIG. 3 is a sectional view of the device illustrated in FIG. 2, showing the adjutage in one position for dis charge;

FIG. 4 is an enlarged sectional view, partly in per- States atent 3,048,307 Patented Aug. 7, 1962 spective, of a portion of the resilient member shown in FIG. 2, and

FIG. 5 is an enlarged sectional view of a portion of the resilient member engaged with the adjutage as shown in FIG. 2.

Referring more particularly to the drawings, a container 10 is provided having a lid portion 12 and a protective cap 14 aflixed over adjutage 16'. The cap may be of any esthetic configuration but ordinarily skirt portion 18 extends about the top of the container and overlaps the outer edges of a mounting cup 20. An elongated resilient member 22, especially adapted for insertion through an aperture in the mounting cup, engages both the cup and the adjutage to complete the assembly of the container and dispensing device.

An upper or first shoulder means 24 is formed on the tubular body portion 26 of the adjutage intermediate open end 28 and transversely apertured end 30. Second shoulder means 32 is formed on tubular body portion 26 intermediate the first shoulder means and the transverse-. 1y apertured end. Valve plug 34 adjacent end 30 may be integrally formed therewith, as has been found preferable, by any appropriate molding process.

The elon gate resilient member 22, which may be made of soft plastic, rubber, or any desirable material, is centrally apertured and comprises a sleeve portion 36 hav ing a valve seat portion 38 on one end. Flexible annular blades 4% and 40b are disposed within the sleeve portion and encompass the inner perimeter thereof adjacent the valve seat portion.

The apertured mounting cup 20, secured to the lid portion 12 of the container, has a sleeve-engaging flange 42 positioned about the edges of an aperture in its bottom. Thus the outside of sleeve portion 36 is snugly engaged by flange 42, and externally situated shoulder 44 laps over the flange when web 46 is sealingly seated against the interior surface of the mounting cup.

The dispensing device is assembled by pushing the sleeve portion 36 of resilient member 22, through the aperture in the bottom of the mounting cup until shoulder 44 is engaged over flange 42 and web 46 is flush against the surface of the mounting cup. Thereafter end 28 of the adjutage is inserted into the valve seat portion 38 of resilient member 22 and forced through until valve plug 34 is positioned against valve seat portion 38. Sleeve 36 is then compressed along its longitudinal axis until the sleeve end opposite seat 38 receives first shoulder means 24 thereby maintaining the resilient member 22 in longitudinal compression which urges the valve plug 34 toward releasable sealing engagement with the valve seat. The second shoulder means 32 compresses an adjacent portion of the sleeve 36 and is wedged therein.

When the device is assembled, second shoulder means 32, of larger diameter than the sleeves central aperture, is wedged against the inner walls of the sleeve portion and cooperates with first shoulder means 24 to restrict longitudinal movement through resilient member 22, thus guarding against accidental dislodgment of the adjutage and consequent separation of the valveplug from the valve seat. The second shoulder means 32 is disposed on the adjutage in spaced relation to the valve plug 34 aridis positioned Within the sleeve adjacent to the flange of the mounting cup. As shown particularly in FIG. 5, an annular face 32a of the second shoulder means extends outwardly from the adjutage in a plane substantially normal to the longitudinal axis of the adjutage to form a sharp edge 32b with a second face 32c of the second shoulder means, the second face extending from the annular face'in a direction away from the valve plug, and forminga relatively smooth outer surface with the adjutage Th'esec- 0nd shoulder means is therefore readily movable Withinthe sleeve in a direction away from valve seat 38, but the sharp edge 32b formed by the intersecting annular and second faces of the second shoulder means engages the inner wall of the sleeve to oppose movement of the said second shoulder means within the sleeve toward the valve seat. Furthermore, sleeve 36 is compressed between second shoulder means 32 and flange 42. Such compression opposes any force exerted inwardly on adjutage 16 and increases with any inward movement of the adjutage to further resist accidental dislodgment of the valve plug.

The assembled dispensing device may be afiixed to a container by suitable fluid-sealing means, such as shown in FIG. 2 of the drawing: a flange portion 48 of mounting cup 20 is placed over bead 50 on container with a resilient sealing material 52 included to efleet a liquidtight joint. The cup is then spun radially outward in the portion 48a to form a tight seal. Although ordinarily a mounting cup may be used to facilitate mounting the adjutage and resilient member on a container, it is contemplated that such a cup may be eliminated, and the container, with the adjutage and resilient member mounted in one of the walls, may be sealed at another point such as, for instance, at the bottom.

In order to dispense the contents of the container, adjutage 16 may be tilted radially, as shown in FIG. 3, thus opening the valve to permit the contents to escape under pressure through transversely apertured end 30, tubular body 26 and open end 28 as indicated by the direction of arrows 54.

Without intending to limit the invention disclosed herein, excellent results have been obtained when the adjutage is formed having an outer diameter of .360 inch at the first shoulder means with a step-down to .250- inch outer diameter between the first and second shoulder means. The inner diameter of sleeve 36 is .M8 inch in the area immediately above blade 40b thus requiring second shoulder means 32 on the adjutage to be wedged within the sleeve.

Blades 40a and 40b annularly encompass the inner walls of sleeve 36 and are especially formed to prevent leakage from the container. They also facilitate tilting of the adjutage while reflected compression is transmitted from the flange. Girdling the centrally located aperture in the sleeve, sharp edged blades 40a, closest to the valve seat, are positioned about the adjutage such that each is inclined toward the valve plug and their edges grasp the adjutage intermediate the transversely apertured end 30 and second shoulder means 32. Blade 40b with an arcuate face is located adjacent the blades 40a and opposite flange 42 around the mounting cup aperture. When the adjutage is tilted the arcuate face of blade 44b, through which the fulcrum function of flange 42 is eflected, provides a bearing across which the adjutage may be readily tilted.

Blades 40a and 40b cooperate during the tilting operation as well as at all other times to prevent leakage from the container by providing a multi-lipped barrier against flow or seepage of the containers contents. Moreover, the arcuate surface of blade 40b cooperates with the opposite resistance of flange 42 and permits all blades to flex slightly upon the tubular body rather than release or slip along the adjutage when the latter is accidentally jarred, thus assisting the second shoulder means wedged against the inner walls of resilient member 22 in main taining the adjutage securely in position.

Others may, by applying current knowledge, readily adapt the invention explained above while retaining certain features which may properly be said to constitute the essential items, which items are intended to be secured by the following claims.
