11 claims. 1

This invention relates to a germicidal receptacle, to wit, a receptacle into which a germicide is projected or shot at intervals to inhibit the growth of certain bacteria which cause odors and infection. An example of such a receptacle is a diaper can.

It is not new broadly to provide a germicidal receptacle. However such receptacles which have heretofore been proposed have had disadvantages either in respect of operation or in respect of manufacture. My germicidal receptacle constitutes an improvement from both aspects. It is reliable in operation and economical to manufacture in quantity. Through use of my invention a non-germicidal receptacle may be converted into a germicidal receptacle.

I provide a germicidal receptacle comprising a receptacle, a cover for the receptacle mounted for movement between closed and open positions, a germicide container carried by the receptacle exteriorly thereof, germicide delivery means extending from the germicide container into position to deliver germicide into the receptacle and a connection between the cover and the germicide container expelling germicide from the germicide container through the germicide delivery means into the receptacle upon movement of the cover between closed and open positions. I provide germicide expelling means cooperating with the germicide container to expel germicide from the germicide container through the germicide delivery means into the receptacle upon relative movement between the germieide expelling means and the germicide container and means maintaining the germicide expelling means in generally stationary position. Desirably the cover is pivotally connected with the receptacle for swinging movement between closed and open positions. The connection between the cover and the germicide container is preferably a constantly maintained connection expelling germicide from the germicide container through the germicide delivery means into the receptacle upon swinging movement of the cover between closed and open positions. Desirably the germicide is expelled into the receptacle upon each closing movement of the cover.

I preferably mount the cover upon the receptacle and provide means including a generally vertically movable member for moving the cover between closed and open positions. The germicide container may be carried by the generally vertically movable member so that the germicide container partakes of the generally vertical movement of said member. The germicidal receptacle preferably comprises an outer receptacle and a removable inner receptacle adapted normally to be disposed in the outer receptacle but removable therefrom for emptying and cleaning. The structure is preferably such that the germicide delivery means extend from the germicide container so that in one position of the germicide container the germicide delivery means may deliver germicide into the inner receptacle and in another position of the germicide container the germicide delivery means are offset from the inner receptacle to permit removal and replacement of the inner receptacle.

My germicidal receptacle comprises relatively movable cooperative elements for injecting germicide into the receptacle, one of such elements being mounted in substantially stationary position, another of such elements being connected with the operating means for movement relatively to the first mentioned such element to inject germicide into the receptacle upon movement of the operating means to move the cover between closed and open positions. In a preferred form of structure the cover is pivotally connected with the receptacle for swinging movement between closed and open positions and there are provided a lever, a link connected with the lever and with the cover to swing the cover between closed and open positions upon operation of the lever, relatively movable cooperative elements for injecting germicide into the receptacle, one of such elements being mounted in substantially stationary position, another of such elements being connected with the link for movement relatively to the first mentioned such element to inject germicide into the receptacle upon operation of the lever to swing the cover between closedV and open positions. I preferably provide a germicide container connected with the link and means for expelling germicide from the container into the receptacle having a portion extending within the container and a portion projecting therefrom. The expelling means are preferably mounted in substantially stationary position so that when the container is moved relatively to the expelling means germicide is expelled from the container into the receptacle. Preferably stop means are provided limiting movement of the expelling means in one direction and resilient means are also provided biasing the expelling means against the stop means, so that the expelling means is maintained in substantially stationary position so that when the container is moved relatively t-o the expelling means germicide is expelled from the container into the receptacle.

The germicide container is preferably connected with the cover operating means and mounted for generally downward-and-inward and upward-and-outward movement relatively to the receptacle when the cover is swung to closed and open positions respectively and means are preferably provided cooperating with the container to expel germicide from the container into the receptacle when the container is partaking of generally downward-and-inward movement relatively to the receptacle. The last mentioned means preferably have a portion extending within the container and a portion projecting therefrom, and stop means are provided limiting generally upward movement of the last mentioned means. I prefer to employ resilient means biasing the expelling means against the stop means so that the expelling means are maintained in substantially stationary position.

in a preferred form of structure my germicide receptacle comprises a receptacle, a cover for the receptacle mounted for movement between closed and open positions, a germicide container carried by the receptacle exteriorly thereof and connected with the cover so that the position of the germicide container is shifted when the cover is moved between closed and open positions, germicide delivery means extendingfrom the germicide container into position to deliver germicide into the receptacle and means connected with the germicide container and positioned by a stationary portion of the receptacle whereby relative movement between such means and the germicide container occurs upon movement of the cover between closed and open positions, such relative movement delivering germicide through the germicide delivery means into the receptacle. The means connected with the germicide container may abut a stationary portion of the receptacle and spring means may press such means against the stationary portion of the receptacle to maintain the same at all times in position thereagainst whereby relative movement between such means and the germicide container occurs upon movemnt of the cover between closed and open positions. The means connected with the germicide container may have a portion tting within a stationary portion of the receptacle whereby relative movement between such means and the germicide container occurs upon movement of the cover between closed and open positions. The means connected with the germicide container may interengage with a stationary portion of the receptacle so that such means is restrained against movement in the direction of shifting of the germicide container whereby relative movement between such means and the germicide containeroccurs upon movement of the Cover between closed and open positions.

Other details, objects and advantages of the invention will become apparent as the following description of a present preferred embodiment thereof proceeds.

In the accompanying drawings I have shown a present preferred embodiment of the invention in which f Figure l is a view partly in elevation and partly in central vertical cross section through a gerinicidal receptacle;

Figure 2 is a view to enlarged scale partly in elevation and partly in central vertical cross section of a portion of the germicidal receptacle shown in Figure l; and

Figure 3 is a fragmentary elevational View of a modified form of germicida receptacle.

Referring now more particularly to the drawings, there is shown in Figure l a germicidal receptacle designated generally by reference numeral 2 which comprises an outer receptacle 3 and an inner receptacle 4. The inner receptacle i may be a removable can such as a diaper can and may be provided with a bail by means of which the receptacle 4 may be picked up and removed from the receptacle 3 for emptying and cleaning. The receptacle 4 in the form shown has an outwardly projecting annular lip 5 which when the receptacle 4 is disposed within the receptacle 3 rests upon the uper rim 1 of the receptacle 3.

A The receptacle 3 may be of any suitable material, as, for example, metal, and may have within its lower portion a member or structure 8 of any suitable or conventional form carrying a pivot Ti upon. which is pivotally mounted a lever I0. The lever la projects forwardly through the wall of the receptacle 3 through a slot H and projects rearwardly through the wall of the receptacle 3 through a slot l2. At its forward end the lever E@ has a treadle I3 adapted to be depressed by the foot of a person wishing to raise the cover nresiently to be described.

The receptacle 3 carries externally thereof a bracket la to which is pivoted at l5 the cover i5. ln Figure l the cover IE is shown in Open or inoperative position. It is adapted to move or swing between that position and closed or operative position by pivotal movement about the axis oi the pivot l5. A link Il is pivoted to the lever i@ at lil and to the cover I6 at I9. When the treadle i3 is depressed the lever l0 turns in the counterclockwise direction about the axis of the pivot 9 viewing Figure l whereby its right-hand end is raised. Upward movement of the righthand end of the lever It moves the link l1 upwardly. Upward movement of the link l1 causes the cover Iii to turn in the clockwise direction about the axis of the pivot l5 from closed to open position. The cover never moves so far that its center of gravity passes to the right of the pivot l5 viewing Figure l. if desired a stop, not shown, may be provided to limit turning movement of the lever l@ in the clockwise direction to insure against the cover becoming overbalanced toward the right viewing vFigure l. Thus the force of gravity is always available to lower the cover from open to closed position by turning in the oounterclockwise direction about the axis of the pivot I5, viewing Figure 1, when downward pressure on the treadle i3 is relieved.

In the form of structure shown the dispenser is designated generally by reference numeral 2! and is mounted upon the link l1 so that the container and cylinder of the dispenser, presently to be described, partake of generally vertical movement with the link Il. The movement of the link l'l is not exactly vertical since the upper end of the link partakes of movement generally about the axis of the pivot l5. I iind it convenient to employ the trunnion of the pivot i5 as means to limit upward move.- ment of the piston as will presently appear.

The dispenser comprises a container 2| shown as being in the form of a glass jar having a metal screw cap 22 applied thereto. The cap 22 has a round opening 23 therethrough at its center. A washer 24 having at its center a similar round opening 25 lies against the under surface of the cap 22. An annular packing retainer 2E having a central opening 21 of the same size as the openings 23 and 25 underlies the washer 24. Annular packing 2S is disposed within packing retainer 26.

provide a mounting bracket 29 which is of generally inverted L shape having a generally downwardly projecting leg 3i! and a generally horizontally projecting leg 3l. The leg 3D of the bracket 29 is connected with the link Il by welding, bolting or otherwise so that in effect the bracket Z9 becomes integral with the link il. The generally horizontal leg 3l of the bracket 2Q has a central opening 32 of the same size as the openings 23, 25 and 2l. I provide a connector 33 having a relatively large upper portion and a relatively small lower portion with a downwardly facing shoulder 34 therebetween. The lower portion of the connector 33 is generally cylindrical and of such size as to fit fairly snugly within the openings 32, 23, 25 and 21. The lower end of the connector 33 is externally threaded as shown at 35. The cylinder 36 has its upper end internally threaded and is screwed onto the threaded lower end of the connector until the connector and the cylinder grip therebetween the leg 3l of the bracket 29. the cover 22, the washer 24, the packing '28, the packing retainer 26 and the packing 28 as shown in Figure 2. Thus the assembly is maintained by the shoulder 34 and the threaded connection between the connector 33 and the cylinder 36` Thus the container 2| and the cylinder 36 together with the associated elements-which have been described form a unit the parts of which are maintained together at all times during operation of the dispenser. The cylinder 36 is open at its lower end as shown in Figure 2, the inner portion of the rim being curved as shown at 31.

The lower portion of the connector 33 has a reduced bore 38 which forms the outlet from the cylinder 36. A piston 39 cooperates with the cylinder 36, the piston being provided with a resilient annular member 40 such las a rubber O-ring which snugly contacts the inner surface of the cylinder when the cylinder moves downwardly relative to the piston. Entry of the O- ring into the cylinder is facilitated by the curved inner rim portion 31; the O-ring is slightly compressed when the piston is within the cylinder. The piston is provided with a piston rod 4| threaded into the piston at 42 and projecting upwardly through the outlet 38 and through the top of the connector 33'. The piston rod 4I passes through a packing nut 43 threaded into the upper end of the connector 33 and having a downwardly and outwardly inclined annular seat 44 against which lies a rubber O-ring 45. The connector 33 has just above the outlet 38 a downwardly and inwardly inclined annular seat 4B against which is adapted to seat a rubber O-ring 41. The -rings 45 and 41 also are adapted to seal against the periphery of the piston rod 4|. A washer 48 underlies the O- ring 45 and a washer 49 overlies the 0ring 41 and a compression coil spring :acts between the washers 48 and 49 to press the O-ring 45 upwardly and the O-ring 41 downwardly; The O- rng 45 is at all times maintained by the spring 56 against the seat 44 and the piston rod 4| to inhibit leakage between the piston rod and the packing nut 43.

Connected with the upper end of the .piston rod 4| so as in effect to be integral therewith is a cap 5| having an enlarged upper portion 52 which is maintained at all times in engagement with the under surface of the trunnion 53 for the cover hinge pin I5. A compression coil spring 54 presses upwardly on the cap 5| and downwardly on the unit through the packing nut 43 so that the upper surface of the portion 52 of the cap 5| remains in contact with the trunnion 53 in all positions of the unit. Thus the piston rod 4| and the piston 39 are maintained at all times at substantially .predetermined elevation and indeed in generally fixed position, although there is some lateral movement of the piston rod and piston, particularly at the upper end of the piston rod, due to the fact that the unit is mounted on the link I1 and the piston and piston rod have guided re- 6 lationship with the unit through the packing nut 43 and the cylinder 36. However the lateral movement of the piston and piston rod may be neglected so far as operation of the piston relatively to the cylinder is concerned.

A delivery conduit or nozzle 55 communicates with the interior of the upper portion of the connector 33, being threadedly connected therewith at 55'. The nozzle is of generally gooseneck shape as shown and has its upper or outlet end flattened as shown at 56 to reduce its cross-sectional area and insure rthe discharge therefrom with some velocity of a shot of fluid upon each. operation of the dispenser.

The spring 50 maintains the O-ring 41 against the seat 46 when the unit moves upwardly relatively to the piston and piston rod but when the unit moves downwardly relatively to the piston and piston rod the liquid forced upwardly by the piston as will presently be explained unseats the O-ring -41 from the seat 46 to permit liquid to pass into the space within the upper portion of the connector 33 and thence into the delivery conduit or nozzle 55. Thus the springpressed O-ring 41 is in effect a check valve permitting upward but preventing downward flow of iiuid therepast. It insures that the space within the upper portion of the connector 33 and the nozzle 55 will remain filled when the unit moves upwardly relatively to the piston. This insures the ejection of a positive shot upon each operation of the dispenser.

When the cover I6 is in closed position the end 59 of the nozzle 55 is disposed downwardly and toward the left from the position of Figure 1, and I find it desirable to have the end of the nozzle disposed just above and possibly in contact with the lip 6 of the receptacle 4. When the treadle I3 is depressed the cover I6 is moved to open position as shown in Figure 1. At the same time the unit comprising the container 2| andthe cylinder 3E is moved upwardly relatively to the piston 39, the uppermost position of the unit being shown in both figures of the drawings. When the unit is in its uppermost position the O-ring 40 which is the portion of the piston cooperating with the cylinder is disposed below the lower end of the cylinder as shown in Figure 2 so that fluid from the container 2| passes into the cylinder. The cylinder lls up with fluid because upon the upon movement of the unit relatively to the piston a vacuum is created within the cylinder sin-ce the upper end of the cylinder is sealed by the O-ring 41. Thus the cylinder is filled even though the level of the fluid in the container 2| is low, although of course the level of the fluid in the container 2| must be at least as high as the lower end of the cylinder 36. The nozzle 55 is maintained filled with liquid through seating of the O-ring 41 on the seat 46 as above explained.

The pivotal movement of the upper end `of the link I1 about the axis of the Ipivot |5 causes the unit, including the nozzle 55, to move upwardly and away from the receptacle 4 so that when the cover I6 is in open position the receptacle 4 may be removed and replaced.

When downward pressure on the treadle I3 is released the cover |6 moves by gravity from open to closed position. At the same time the link I1 moves downwardly. Since the unit is mounted on the link the unit moves downwardly with the link.` The end 5G of the nozzle 55 moves downwardly and inwardly so that when 'the cover reaches closed position the end of the nozzle lies 7 on or close to and projects slightly inwardly of the lip t.

As above explained the spring 54 maintains the upper end or the piston rod always at substantially fixed elevation through its contact with the trunnion 53. As the unit moves downwardly relatively to the piston rod M and piston 39 the piston enters the lower end of cylinder 36 and forces the fluid in the cylinder upwardly relatively to the cylinder. Such upward forcing of the lluid in the cylinder unseats the O-rmg @l and the fluid passes into and through the nozzle 53 so that a shot of the fluid is projected from the nozzle into the receptacle 4. When next the treadle it is depressed the unit again rises to the position shown in the drawings, the vacuum within the cylinder' 33 causes the cylinder to become again nlled with fluid and the parts are ready for repetition of the cycle. n

Figure 3 shows a modied form of germicidal receptacle in which parts corresponding to parts shown in Figures l and 2 are identied by the same reference numerals but each with a prime aflixed. The structure of Figure 3 differs from that of Figures l and 2 in that the piston rod 4l instead oi having a cap like the cap 5| has its upper end turned at right angles into generally horizontal position as shown at 5l. The spring "ad or" the form of structure of Figures l and 2 is dispensed with in the form of Figure 3. Disposed about the pivot l5 is a bracket 58 havingn a depending portion 59 which has an opening to through which the substantially horizontal portion 5l of the piston rod 4i passes. The bracket 53 is stationary so that the piston rod in the form of Figure 3 lits within a stationary portion of the receptacle 3 whereby relative movenient between it and the gerinicide container 2 l occurs upon movement of the cover between closed and open positions, such relative movement delivering germicide through the germicide delivery means into the receptacle. The portion 5l of the piston rod interengages with the bracket 53 so that the piston rod is restrained against movement in the direction of shifting of the germicide container 2l although the portion 5'! may slide laterally in the opening Sil when the gerinicide container moves relatively to the piston rod.

The dispenser per se, which is of broad utility, is claimed in my copending application Serial No. 309,3()0, iiled of even date herewith.
