May 1, 1962 A. J. LA COTTA DISPENSING APPARATUS 2 Sheets-Sheet 2 Filed Sept. 24, 1959 ATTORNEYS 3,032,081 DISFENSING APPARATUS Andrew .I. La Cotta, 515 Second Ave., .lessup, Fa. Filed Sept. 24, 1959, Ser. No. 842,123 13 Claims. (Cl. 141-662) This invention relates to apparatus of the type adapted to dispense toothpaste. More in particular, this invention relates to such apparatus that is arranged to be mounted fixedly on a Wall or the like, and that includes means automatically operable to apply toothpaste to a toothbrush brought into contact therewith.

During recent years there has been a considerable trend toward the use of presssurized toothpaste dispensers for applying the paste to the brush. These dispensers typically comprise a hermetically-sealed metal can formed at the top with a small plastic outlet spout and a manualiy-operable valve bottom to control the how of toothpaste through the spout. Such dispensers have a number of advantages as compared to the earlier deformabie toothpaste tubes, e.g. the cans are not easily broken, and can store a substantial quantity of toothpaste without any significant risk of spoilage.

However, the pressurized dispensers now used suffer from several defects. In particular, the container normally' is held with one hand while a finger or thumb of that hand operates the valve button to apply toothpaste to a toothbrush held in the other hand. This operation not only is awkward and diflicult to perform, especially because the flow valves require substantial pressure to operate, but in addition if the users hands are slightly moist there is a tendency for the container to slip out of his grasp. Moreover, the two-handed operation required with present dispensers makes them unsatisfactory for crippled persons having the use of only one arm or hand.

Accordingly, it is an object of this invention to provide dispensing apparatus of the type described that is superior to such apparatus provided heretofore. It is a further object of this invention to provide a dispensing device operable to apply toothpaste to a brush when the brush is moved into engagement with a part of the dispensing device. It is a still further object of this invention to provide such a device that is simple in construction, reliable in operation, and economical to manufacture. Other objects, aspects and advantages of this invention will in part be pointed out in, and in part apparent from, the following description considered together with the accompanying drawings, in which:

FIGURE 1 is a perspective view of a toothpaste dispensing device constructed in accordance with this in vention, and shown in toothpaste dispensing condition;

FIGURE 2 is a vertical section of the device shown in FIGURE 1, but with various operating parts in normal position;

FIGURES 3 and 4 show different positions of the valvecamming mechanism;

FIGURE 5 is a rear perspective view of the toothpaste dispenser, particularly showing the slide-locking arrangement;

FIGURE 6 is a perspective view of the dispenser housing in loading position, ready to receive a pressurized toothpaste container;

FIGURE 7 is a detail view, partly in section, of the spout extension tube; and

FIGURE 8 is a perspective detail of elements of the valve-camming mechanism.

Referring now to FIGURES 1 and 2, the dispensing device comprises an octagonal housing 10 within which is mounted a conventional pressurized toothpaste container 12 of cylindrical shape. Container 12 holds a supply of toothpaste together with a pressurized propeltfates Patent lant, and at its top is provided with a vertically-depressable pushbutton 14 for operating the usual internal valve for controlling the flow of toothpaste out of the container. To the right of the pushbutton 14 is a soft plastic outlet spout 16 into which is screwed a metal extension tube 18 which passes through a slot in housing 10. Tube 1? is provided with stop members 19 (see also FIGURE '7) which engage the housing wall and assure that the container 12 is maintained in operative position with respect thereto. Tube 18 also is formed with a down-turned end tip 2% through which toothpaste flows when pushbutton 14 is depressed.

Immediately above housing It is a cap 22 which contains a mechanism for depressing pushbutton 14. This mechanism includes a cam bar 24 pivoted at its left-hand end in an aperture in a fixed plate 26. This bar is formed at its right-hand end with a stud 28 which is fitted into a rotary cam plate 34 and passes through a vertical slot 32 in a second fixed plate 34 integral with the first plate as. The lower part of cam plate 3t? is fastened to an operating lever 36 which consists of a rod arranged to extend through an inverted V-slot 37 (see FIGURE 3) in fixed plate 34 and to pass downwardly around the extension tube 18 to a level beneath end tip 20 of this tube. At its lower end, lever 36 is bent back on itself to form a toothbrush-receiving portion 38. The upper and lower parts of this portion 33 are spaced close together to form a recess to receive the solid body 40 of the toothbrush 42 without, for hygienic reasons, permitting the bristles of the brush to touch the operating lever.

When the toothbrush 42 is pressed longitudinally against lever portion 38, this portion will rotate lever 36 from its normal position shown in FIGURE 2 to the operating position of FIGURE 1, and this movement of lever 36 will correspondingly rotate cam plate 3t). This cam plate (FIGURES 3 and 8) is of triangular shape, and its upper edge is in contact with a horizontal lip 44 on the top of fixed plate 34. Thus, as the cam plate rotates from its normal position shown in FIGURE 3, it shifts stud 28 and cam bar 24 down in a pivotal movement about the first fixed plate 26, to the toothpaste expelling position shown in FIGURE 4. During this movement, operating lever 36 is correspondingly shifted down into one of the two lower legs of the V-slot 37 in plate 34. It will be apparent, of course, that if lever 36 had been rotated in the opposite direction, it would have been shifted down into the other of these two legs, but in either event the cam bar 24 moves in a downward direction.

Threaded in the cam bar 24, approximately at its midpoint, is a control element comprising a push rod 46 which extends down through a hole 48 to engage a stifiiyflexible metal tongue 59. This tongue (see FIGURE 6) is held firmly at its left end, and has a flared-out tip 52 adapted to seat against pushbutton 14-. When cam bar 24 is shifted downwards by the camming action described above, the resultant motion of push rod 46 presses tongue 50 against pushbutton 14 to operate the valve in container 12 and cause toothpaste to how through extension tube 18 onto toothbrush 42.

Push rod 46 is slotted at its upper end to permit a screw-driver adjustment of the vertical positioning of this rod, so as to control the amount of toothpaste dispensed for a given displacement of the operating: lever 36. The cap 22 is formed with a hole 47 through which a screwdriver may be inserted to make this adjustment. The flared-out end 52 of tongue 50 is adapted to spread the force of push rod 46 over a relatively wide area of pushbutton 14, and thereby prevent damage to the pushbutton which conventionally is made of soft plastic.

It should particularly be noted that operating lever 36 swings in an arc defining a vertical plane which passes through end tip 2%) of extension tube 18. Thus, as the lever portion 3% is shifted laterally by the toothbrush 42 away from its normal position, the bristles of t e brush move directly beneath the end tip 2%) so that the dispensed toothpaste may be applied evenly along the length of the bristles.

Referring now also to FEGURES 5 and 6, it will be seen that the octagonal housing 19 is pivotally pinned at its lower edge 53 to a channel member 54. As shown in FIGURE 2, this channel member 54 is formed at its bottom with a horizontal shelf 55 on which container 12 is seated. This cannel member is slidably fastened to a frame plate 56 by means of a back-up plate 58 and bolts 60 which extend through a vertical slot 62 in the frame plate. Frame plate 56 is adapted to be firmly secured to the wall of a bathroom by means of the usual bracket strip 63.

A locking lever 64 is pivoted on the frame plate 56 by a rivet 66, and is movable by a finger tab 68 into and out of a position (shown in FiGURE 5) where its springcurved end 76 engages the back-up plate 58 to hold channel member 54 in its upper position. By manually operating tab 6%, this locking lever may be pivotally shifted to an unlocking position to free the back-up plate 58 for downward movement, and the housing can then be slid down and tilted out to the loadng position as shown in FIGURE 7. In this position, an emptied container of toothpaste can be replaced by a fresh container, and the housing again slid up into operative position as shown in FIGURES l and 2.
