'5 Claims. (Cl. 141-360) This invention relates to improvements in pressurized containers for semi-automatically dispensing paste-like compositions, such as tooth paste, or compositions of foam-like consistency, such as aerated shaving cream.

Containers for housing paste-like compositions under pressure, and having a valve-controlled nipple through which the paste may be semi-automatically dispensed, under pressure, when the valve is opened, are Well known. In manipulating these devices, it is customary tograsp the container in one hand, while the pressurized paste is discharged, through the nipple, into the other hand, or is deposited upon some tool or article held in the other hand. Moreover before dispensing the pressurized contents from the container, it is customary to shake the container to agitate its contents.

One object of this invention is an improved valve-controlled, pressurized, container, whose contents may be deposited directly, either into the actuating hand, or upon' the tool which actuates the control valve.

Another object is an auxiliary device having a dispensing orifice, which device can be detachably attached to the valve-controlled discharged nipple of a pressurized container, in such manner, that when either the hand, or a tool, is brought into actuating-registry with the valvemanipulating mechanism of the auxiliary device, the said hand, or tel is also brought into registry with the dispensing orifice of said auxiliary device, to receive the paste, or other composition, discharged from the pressurized container through the dispensing orifice of the auxiliary device.

' Another object is an improved pressurized container which dispenses its contents equally well either in a horizontal, or a vertical, position.

Another object is to eflect agitation of the contents of the pressurized container while said container is mounted in fixed position.

Other objects will appear from the detailed description, which follows.

The pressurized container '20 (Fig. 1), may be filled with any suitable paste-like composition, such as shaving cream in aerated form. The conventional container 20 is generally cylindrical. i

To effect agitation of the shaving cream, the container 20 is mounted in an upside-down position, be

tween the resilient clamping jaws of the upper, and lower, clamping members, 21 and 22, which are mounted upon a plate 36 (Fig. 10), supported upon the hollow stem of a T-shaped bracket 23 (see Fig. 10). The bracket 23 is mounted to rotate upon a wall plate 24 (-Figs. 1 and 10), to effect agitation of the container-contents, by rotating the plate 36 which carries the clamping members 21 and 22 the clamping jaws whereof grip the body of the container 20 (Fig. l). The means for effecting rotation of the bracket 23, are best shown in Fig. 10. A stud 25 is formed integral with the winged plate 30. The stud 25 passes through a central opening formed in the base flange 29 which is integral with the hollow stern of the bracket 23 ('Fig. 10). A coiled spring 28 is mounted upon the stud 25, between the face of the flange 29 and a washer 26 which presses against the end of the coiled spring 28 under control of a lock nut 27 threadably mounted upon the threaded free end of the stud 25. By adjusting the lock nut 27 along the stud 25, the washer 26 varies the tension in the spring to regulate the pressure applied between the abutting faces of the flange 29 and of the winged plate 30. The winged plate 30 is seated in a recess 31 formed in the back wall of the wall plate 24, but only the hub of the winged plate 30 passes through the wall plate 24 from back to front, the wings of said winged plate 30 being seated in the recess 31, and terminating substantially flush with the back face of wall plate 24, or

being contained within the face of said wall plate 24 (Fig. 10).

Lugs 32 and 33 formed integral with the rear face of the flange 29 protrude rearwardly from said flange, and register in similarly sized cavities formed in the abutting face of the winged plate 30, to index the flange 29 and its bracket 23 at the end of each revolution thereof upon the winged plate 30. The lugs 32 and 33, and their cavities, are of different sizes, and are eccentricaily spaced, to insure a complete (360 degree) revolution of the bracket 23, and the return of the container to its upside-down position as each revolution of the bracket 23 is completed. Thus the operator may spin the container 20 once or twice, until the lugs click in the cavities, and relock the container upside-down.

.(Fig. 1).

when the lugs 32 and 33 return into .positiqnof registry 'with. their respective cavities in the abuttingtace ofthe hub of the winged plate 30, the coiled spring pushes the flange 29 into contact with thehub of winged plate 36 and reseats the lugs 32 and 33 in their associated cavities in the hub of the'winged plate 30. fhs the lugs.32 .and' 33 are eccentrically spaced, they cannot register with the.

H wrong cavity inthe plate 30.

The clampingjaws of "the clamping members 21 and 22, are provided with oppositely disposed, spaced, fingers 34, 34 (Fig. l),;which enter the-opposite ends-of the tubular bushings 34a, 34a "which giipgthe container 20 The-clamping members 21 and 22 may be secured to-the'plate 36 in' any preferred manner, as by spot welding, riveting, or otherwise.

. If'thewall plate 24"is' composed of a ceramic, or of H a plastic, material, the platef24 may be bonded to the wall, or other support 35- (Figs. land by means of a suitable bonding agent which'is normally non-tacky;

but which becomes tacky when moistened with water, or other solvent, and which, while in a tacky condition, will bond with glass, tile, wood,'-' plastic, metal, or the like; Such bonding agents are well known, and 'are I readily available uponthe open market.

OnecontrolQvalvemechanism for a pressurized 'conttainer 20, is shown in'Fig; 13. Theneck 40 (Fig. 1) er the container 20 is' suitably sealed bya cap 41 (Fig.

The cap 41 is provided with a central opening wherein anipple' 42 is slidably mountedl The nipple '42 has an enlarged outer end which projects out'of the container 20, and a reduced inner end which is an integralextension .of the head of 'a'piston 45. 'Piston 45 .is telescopically mounted to slide in a cylinder 46 positioned inside the container A series of ports 43 (Fig. 15), extend through the, wall of the nipple 42. The ports 43 are located in the reduced-inner end of the nipple and are normally enclosed and sealed by a rubber Washer 44. When pressure is appliedto the outer end ofnipple 42, its reduced inner end projects through the rubber washer 44 (as shown'in broken lines, Fig. 15), to uncover the ports 43 and thus establish a restricted passageway for the'flow of the pressurized fluid composition housed in the container 20, from said container 20, through the ports 43, into the nipple 42; Since the reduced end of the nipple 42 is formed'integral with the head end of the piston 45, the sliding movement of the nipple forces the piston 45 into the cylinder 46 against the opposition of the spring follower 47 which is positioned between the inner end of said piston 45 and the opposed end wall 48 of the cylinder 46; Thus telescopic pressure applied to the outer end of nipple 42, s'lides piston 45 along the cylinder 46'towards its end wall 48, against the plastic tube 52 (FigsglSand 13). A r

The piston ;45 is not a true cylinder.

opposite segments of said cylindrical piston'have been a removed, so that said piston only engages some portions of the wall of the cylinder 46 but is spaced away from other portions of the cylinder wall, the curved wall of the cylinder and the non-circular'portio'ns of the wall of the piston, in conjunction, defining passageways, said.

passageways extending co-axially relative to the cylinder 46 and the piston 45 to establish communication between the chamber defined by the container 20, and the nipple 42, under. control of the ports 43, by way of the plastic; 75

Diametrically' tube 52, piston-cylinder passageways, ports 43, to the interior of the nipple 42.

As best shown in Fig. 13, the'plastic tube 52 is bent to ofiset the tube 52 towards the wall of the container 20,- and is rebent at 53 so that the tube 52 extends along the inner wall of the container 20, and terminates at 54 in spaced proximity to the. convex bottom wall 55 of the container 20. *1 a 'An actuator assembly unit'57 is 'demountablyii'nountable upon the neck .40 (Fig.1) ofthe container 20. I The a unit 57,.includes a bcll-mouthedadapter 56 shaped and sizedto form'a cap'whichengagesthe neck 40 of the container 20 with a tightfit '1 The unit 57 also includes a dispensing head 58 which, forms anintegral extension of the adapter 56. a The head 5 8,is provided .with a duct or passageway 66 which extends throughthe dispensing 'head 58, through the valve-actuator 59, to the elbow 67 which is enlarged to receive, the outer'end of the nipple a 42 with a sealing fit. The elbow 67 is stepped toform a shoulder (Fig. 15) which limits the depth of penetration of the nipple 42 in' the elbow 67 to prevent closing of the duct 66 in the bend of the elbow.

The valve-actuator 59 is resiliently hinged at 60, upon thelip of the '-adapter-56, so that the'actuator 59 may swing inwardlyiinto' the mouth 61 of the adapter 56 when any pressure is applied'to the actuator'59l The actuator 59 is recessed at 62 to receive the head of a a tooth brush' 63, and the dispensing head 58 is shaped somewhat in the form'of-an invertedletter U, so that,

when the bristles 64 of the tooth brush 63 are positioned beneath the, dispensing orifice 65 of the dispensing head 58 of the actuator assembly unit 57, the head of the tooth brush will'be in position to register with the recess 62 in the actuator 59 to actuate the control-valve, and deposit a ribbon-like stream of toothpaste upon the bristles 64, "by way of the ports 43 (now open), nipple 42, elbow ducts 67, 66 and dispensing orifice 65.

The moment that the tooth brush 63 is withdrawn from the recess 62, the valve-actuator 59 swings back into normal position and draws the nipple 42 with it to seal Oil the ports 43 within the washer 44. Thecoiled spring 47 restores the piston 45 to normal position, and the'controk brush may be used to actuate the control valve of the dispensing apparatus, and to receive the deposit of the tooth paste so dispensed, all by one-hand operation of the tooth brush itself, leaving the other hand entirely free.

By offsetting the tube 52 alongtheinside Wall of the container 20, and extending the tube to a point in close proximity to the convex bottom 55, the contents of the container 20 may be more completely exhaustedirom the container in its cradled position (Fig. '12). The

cradle bracket 68, offset tube 52,"-and convex bottom 55,

in conjunction, thus cooperate to efiect the efficient operation of the dispensing apparatus to the point of maximum exhaustion" of the contents of the pressurized container,

70, and the container is secured in an upsidedown posi'-,

tion between the clamping jaws of the upper, and lower,

clamping members, 21 and 22, carried by the plate 36 of the bracket 23, supported asby the wall plate 24. The actuator 70 normal-1y assumes a position, substantially as shown in full lines in Fig. :1, but when the handis inserted,

palm upwards, in the bow-shaped opening of the actuator 70, and the actuator is swung by. the movement of the.

hand in the direction of the arrow (Fig. 1), into the position indicated in broken lines. in said figure, the nipple 42a is displaced sideways, thus opening the control valve and discharging the shaving cream through the dispensing orifice 65a (Figs. 1 and 5), into the palm of the hand. The actuator 70 is used in association with the adapter 71 (Figs. 1 to 4). The adapter 71 resembles an inverted bell-shaped attachment whose inverted skirt or flange defines an annular collar 72 (Figs. 2 and 3), sized to fit around the neck 40 of container 20 with a tight fit (Fig. 1).

The actuator 70 is mounted in the adapter 71, in such manner, that the actuator is rockable in the adapter to actuate the control-valve to dispense the contents of the pressurized container 20, as desired. The actuator 70, and the adapter 71, are preferably molded pieces, and to reduce the cost of manufacture, these pieces may be molded out of plastic materials, which give good results. The pieces may also be made of metal, or other materials, if desired.

Merging with the collar 72 of the adapter 71, is a crown 73 (Figs. 2 and 3), and said crown is further extended to form a socket or holder, having an end wall 74, two side walls 75 and 76 merging with said end wall 74, and a slotted bottom wall 77 (Fig. 4); said end wall, side walls, and slotted bottom wall in conjunction, thus defining said socket or holder for containing the head 78 of actuator 70.

The bottom wall 77 of the adapter 71, and the bottom wall of the head 78 of the actuator 7 are interfitted by means of bevelled tongues, and reversely bevelled grooves, to define a fulcrum or hearing whereon the head 78 is rockably supported in or by the socket or holder, the side walls 75 and 76 of said socket also serving to maintain said head 78 in correct alignment and thus maintain said fulcrum connection. The bottom wall 77 of the adapter 71 is subdivided into two outer tongues 79, 79 and a central tongue 80, and these three tongues are correlated with three grooves or guideways 81, 81 and a central groove 32 formed in the lower wall 83 of the head 78. The tongues 79, 79 and 83 are wedge-shaped and taper downwardly and outwardly from the end wall 74, along their respective side walls 75 and 76, to a thin edge at the entrance to the socket or holder. The three grooves or guideways 81, 81 and 82, are bevelled to receive and accommodate said Wedge-shaped tongues 79, 79 and 80; and the slots or openings 85, 85 formed between each of the tongues 79, and the central tongue 80, are sized to receive and accommodate the tongues 86, which are formed between each of the grooves 81 and the central groove 82 (Fig. 6); said thus interfitted and correlated head 78 and socket therefor, constituting an attachable and detachable actuator 70, rockably supported upon, or within, the socket element of the adapter 71 (see Fig. 1). The central orifice 65a in the throated passage or socket S4 registers with the nipple 42a (Fig. 1), and connects at its lower end with the central groove or guideway 82 (Fig. 6), to provide a dispensing outlet for the nipple 12a. The nipple 42a fits the throated passage or socket 84 with a tight fit to interlock the head 78 in the adapter 71. The nipple 42a is sufficiently resilient to flex when the head 78 of the actuator 70 is rocked in the adapter 71 (Fig. 1), from the position in bold lines to the position shown in broken lines in said figure. When the actuator is in the position shown in bold lines, the central tongue 86 (Figs. 3 and 4) closes oif the orifice 65a (Fig. 1); but when the actuator 79 is rocked into the position shown in broken lines in Fig. 1, the central tongue 80 uncovers the orifice 65a, and said orifice is now open and free to dispense paste, or shaving cream, as it is discharged through the nipple 42a from the pressurized container 29. The actuator 7 0 is well suited for use in conjunction with a pressurized container for dispensing shaving cream into the palm of the hand, see Fig. 1.

The adapter 71, however, may also be attached to the tainer (Fig. 13), in which case, the actuator 70 is replaced by the tooth-brush-actuated actuator 90 (Fig. '7),

which is interchangeable with the actuator 70 of Figs. 1, 5 and 6. The actuator 99 includes a head 78b the lower wall whereof is formed with grooves or guideways 81b, 81b and 82b, which, when they are correlated with the tongues 79, 79 and of the adapter 71, form a rocking connection for the actuator 90. Nipple 42a of the container 20 engages in the throated passage or socket 84b with a sliding fit, and is extended through the bottom wall 83b of the head 78b by the orifice 65b. The actuator is designed to be operated by the pressure exerted through the head of a tooth brush. Actuator 90 is accordingly formed with a tooth brush holder formed by the flaring side walls 91, 92 and the bottom wall 93, said side, and said bottom, walls, in conjunction, defining a trough-like structure, sized to receive the head of a tooth brush, with the bristles facing upwardly towards the orifice 65b, so that, when the tooth brush is placed in the trough 94 with slight pressure, the actuator 90 will carry the nipple (42a, Fig. 1), ofif-normal, and open the control-valve of the container 20, while simultaneously uncovering the orifice 65b, to provide a dispensing outlet, through which outlet a ribbon of paste may be deposited upon the bristles of the tooth brush. Whenthe tooth brush is removed from the trough 94, the controlvalve closes, and the tongue 84 of the adapter 71 moves across the orifice 65b to close off said orifice.

Thus the common adapter 71 may be used in conjunction with either the actuator 70, or the actuator 99,

ependent upon the nature of the contents of the pressurized container. The container-holder (Figs. 10 and 11), is equally adapted for use either with a container of shaving cream, or of tooth paste, as desired.
