5 Claims. 1
This invention relates to the art of dispensing, pa cu arly to the di p nsing of p surized fluids, More specifically, the invention relates to valved closures for pressure containers.
valved dispensing containers for spraying aerosols of insecticide and the like are well known and Widely used. similarly, valved Pressure .0011- tainers for dispensing pastes and aerated fluids are commonly employed, cans filled with cream nd gas und r pressur or d spensing wh pped cream eing a well known xample Most dis- Densers of th se t pes being int nded .ior but a single use, the complexity and cost of the elemen the eof is of pr mary mportance. It s a par ic ar object of the pres nt in e n t p o vide a simplified, inexpensive, unitary valved l u adapt d for us in. d p ns rs of the type indicated and similar pressure containers.
t is a u er object o t e invention to pro vide a valved closure for pressure containers havs. ing finely controllable variable open ng haraceristies, a d closing qu ckly and p ely due prima t inter l pres ure w thin th c ntainer.
Another object of the invention is to provide a unitary valved pressure container closure constructed of resilient material, adapted to frictionally engage a tubular discharge member operable to controllably open said closure by axial m ement r tive the eto.
Another object is to provide a novel dispensing container for pressurized fluids.
Further objects will be in part obvious and n part poi d out h e nafter- T e nvention and t e novel features thereof may best be m d cl ar f om the fol owing description and the accompanying drawings, in which;
F gur l is a sect onal el vation l vi of an xem l y embo iment of the present inventio apted as a disp ns g ontainer for w ipped cream a d he like;
F g re 2 is a i w co responding to F ure 1. but showing the valved closure and associated dish e member of the dispens i ope r dis pehs ng position;

Figure. i i a bottom plan view oi the alved r unded pressure surface 26.
l---'( of Figure 6, showing details of the slit conformation of the modified closure.
Referring .to the drawings, in Figures 1 and 2 is shown a pressure container in the form of metal can H, formed at its up r end into a neck 12 which terminates in the mouth-defining bead I 3. Can I I is of the type commonly employed to package cream and gas under pressure, for dispensing as whipped cream. Positioned partly within neck 12 of the can is the valved closure indicated gen rally as I4, constructed in unitary form of resilient material such as rubber. cloure It comprises a cylindrical body member 1.5. provided at its outer end with the laterally ex tending annular :fiange l6. Bore H, of substantially smaller diameter, enters the outer end of body member 15 and extends partially therethrough, the spacing from the bore bottom to th adjacent end of the body member being substantial and of the order of the wall thickness of the body member external of the bore, for rest-- ns presen ly parent. A transverse slit 18 ex. tends from the periphery of the body member to bore I7, and may constitute a straight out of proper depth into the side of'the body member,
as indicated in Figure 4. Longitudinally, slit I8 is disposed intermediate the inner surface of flange l6 and the bottom of bore I1, preferably about midway therebetween. A relatively short integral neck portion 19 may extend from the outer end of the body member about the bore, the outer diameter of the neck portion being substantially smaller than that of the body member.
Closure flange [6, it will be noted, is of greater diameter than the mouth defined by can bead I3, and may be retained thereagainst by an apertured crown cap 20, crimped about the bead in the usual manner, whereby the closure flange is compressed therebetween to properly position the closure and to form an eflective seal. The cap aperture 22 encloses and desirably fits closely about necl; portion [9 of the closure. Obviously, the valved closure may be otherwise secured to the pressure container, as for xample by an apertured screw cap engaged to a threaded neck.
s shown in Figures 1 and 2, a tubular dish e member indicated generally as 23, contructed of metal or suitable synthetic plastic material, is irictio ally retained in bore I! of he cl sure and extends axially therefrom. The disoharge member comprises body 24 having a longitudinal passage 25 extending substantially therethrough, the inner end of the discharge member body preferably terminating in the Passage 25 may terminate somewhat short of the inner end of the discharge member, and is joined at this point by a plurality of radially spaced lateral passages 27 extending through the body wall and joined at their outer ends by the annular communicating groove 28. Intermediate the length of the discharge member body an annular grip flange 29 extends outwardly therefrom, the grip flange terminating, in the embodiment shown, in downwardly depending skirt 3!]. The outer end of the discharge member body may be provided with the usual longitudinal slots 32, adapted to shape the stream of whipped cream issuing therethrough into decorative fluted form.
The dispenser elements normally occupy the relative position shown in Figure 1, slit '8 being maintained firmly closed by'the internal pressure of the container contents exerted against the inner end of the valved closure. To dispense the contents thereof, the container may be inverted in the usual manner, grasped in the hand with two fingers overlying grip flange 23, one on either side of the discharge member body. So held, the discharge member may readily be displaced axially and inwardly relative to the valved closure with easily controlled force, whereby the dispenser elements are caused to assume the relationship shown in Figure 2. Axial inward movement of the discharge member, it will be apparent, causes pressure surface 26 thereof to press against the bottom of bore ll, axially deforming the valved closure and causing slit l8 to open, whereby the contents of the container may pass therethrough to groove 28 and lateral passages 21 of the discharge member, and thence through passage 25 to the discharge end thereof.
The side and end walls thereof being of substantial thickness, the valved closure possesses adequate inherent rigidity and resilience to function satisfactorily entirely without reinforcement. In conjunction with this feature, the longitudinal disposition of slit l3 intermediate flange I 6 and the bottom of bore I! has been found to effect finely controllable variable opening characteristics in the valved closure, whereby the rate of fiow of whipped cream in the example may be precisely controlled by finger pressure. Additionally, so constructed the valved closure closes quickly and positively on the release of opening pressure exerted by the discharge member, there being no tendency of the material flowing through the slit to maintain it in open position. Furthermore, the slit being spaced from the bottom of the bore, the inner end of the discharge member cannot enter the slit to cause malfunction in this manner.
The groove 28 and lateral passages 21 of the discharge member are so spaced from the pressure surface 26 thereof as to be generally aligned with the closure slit, especially when the assembly is in open position. If desired, the groove and lateral passages may be so positioned as to align with the closure slit only in open position, whereby in closed position the blank inner end portion of the discharge member will face the inner edge of the slit, as shown in Figure 1, functioning in this case as an additional seal.
Material issuing from the closure slit is conducted by discharge member groove 28 to all lateral passages 2'! simultaneously, whereby even and full fiow is effected at all times when the dispenser is in open position. The sharp change in direction of the issuing material in passing from lateral passages 21 to longitudinal passages 25, especially in the case of pasty materials such as whipped cream, assists in effecting uniformly optimum aeration of the material.
The short neck portion l9 not only functions to maintain alignment between the valved closure and the crown cap, but also separates the discharge member from the edge of the cap aperture whereby no binding therebetween can take place, and elongates the bore H to more effectively frictionally engage and retain the discharge member therein. Obviously, however, the discharge member may be readily removed therefrom for reuse, and need not be supplied with each dispenser unit.
The valved closure [4 is not limited in utility to the particular dispenser illustrated in Figures 1 and 2. In Figure 3, for example, the closure is shown in association with an apertured flat wall 33 of a pressure container 34. In this application also the closure is employed in conjunction with a discharge member 23, not shown, functioning in all respects in identical manner with the embodiment previously described. In this example, the valved closure may be inserted into the aperture of container wall 33 before filling, being adequately retained in place by frictional engagement of the edge of the aperture to neck portion 19 of the closure. It will be apparent that when the container'is pressurized, the valve closure will be maintained in place by pressure exerted against the underside of flange 16, whereby the flange will form an effective seal with the container wall 33 about th aperture.
A further embodiment of the invention, particularly adapted as an aerosol dispenser, is illustrated in Figures 5 to 7. In this modification, a metal cup 35 is suitably aflixed to bead l3 of the can and positioned within the neck thereof, the cup being joined at its inner end to an elongated tube 36 extending therefrom substantially to the bottom of the container, to permit upright dispensing. The cup 35, as shown, is of suitable size to enclose body member l5 of the valved closure without contact. As best shown in Figure 7, the body member of the valved closure is provided with a plurality of radially spaced slits IS, the slits being coplanar and extending as before from the periphery of the body member to the bore [1.
In conjunction with the modified dispenser a modified discharge member 23, adapted for side delivery, may be employed. As shown in Figures 5 and 6, the discharge member comprises tubular body 31, provided with a longitudinal passage 38 extending therethrough and a plurality of radially spaced longitudinal slots 39 at the inner end thereof. A metal cap member 10 is suitably affixed to the outer end of body 31, provided with suitable passage 4| therethrough for discharge of the aerosol through laterally disposed nozzle 42. Wing grips 43, adapted for finger manipulation, extend outwardly from cap member 49.
This modification functions similarly to that of Figures 1 and 2, the discharge member being displaced axially and inwardly relative to the valved closure by finger pressure exerted on wing grips 43, whereby the inner end of the closure is axially deformed and the slits I 8' caused to open. The pressurized container contents may thereupon pass upwardly through tube 36 to cup 35, through the open slits l8 and slots 39 of the discharge member body, and thence through the passages of the body member and cap member to nozzle 42 for discharge. The particular slit configuration of the valved closure has been found to be especially desirable in aerosol dispensing, the opposed slits giving rise to oppositely directed high velocity fluid stream impinging within the discharge member to effect fine atomization of the dispenser contents. As in the case of the modification first described, the valved closure of Figures 5 and 6 possesses finely controllable variable opening characteristics, and closes quickly and positively upon release of the opening pres sure exerted by the discharge member.
The present invention involves distinct packaging and shipping advantages over similar devices presently in use, due to the fact that in all modifications the discharge member may be readily detached, thereby dOing away with all projection above the cap line and avoiding the possibility of damage during shipment or tamper ing with or release of the contents of the containers. The outer opening of the closure bore may be sealed with a label or the like, whereby the closure may be sealed to maintain sterility and prevent tampering. The discharge member, if desired, may be packaged separately in an individual sterile wrapping.
It will thus be seen that there has been provided by thi invention a structure in which the various objects hereinbefore set forth, together with many practical advantages, are successfully achieved. As various possible embodiments may be made of the mechanical features of the above invention, all without departing from the scope thereof, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawings is to be interpreted as illustrative, and not in a limiting sense.
