The dispenser includes a cabinet in which a pad of paper blanks is suspended, and a manually actuatable ejector mechanism is mounted on the cabinet for engaging one of the blanks at a time to permit dispensing of same. The blanks are disposed in a stack secured to a mounting member. The mounting member is provided with a pair of openings for permitting it to be supported on a pair of hangers provided within the cabinet. The hangers are asymmetric relative to the vertical centerline of the cabinet, and the openings in the mounting member are also asymmetric, whereby the pad of blanks can be supported within the cabinet only in a proper orientation for permitting dispensing of the blanks.
8 Claims, 9 Drawing Figures DISPENSER FIELD OF THE INVENTION This invention relates to a dispenser for paper blanks and, in particular, to a dispenser adapted to dispense disposable toilet seat tissue covers.
BACKGROUND OF THE INVENTION Dispensers for permitting the individual dispensing of folded paper blanks or sheets are well known and are widely used in buildings such as schools, hospitals, factories, offices, restaurants and the like. One such dispensing device is disclosed in U.S. Pat. No. 2,931,536, which patent is owned by the Assignee of this application. Dispensers of the type disclosed in the abovementioned patent operate in a highly desirable and satisfactory manner so long as they are properly serviced. To permit proper operation of the dispenser, the pads are normally suspended within the cabinet on hangers so that the pad mounting member faces forwardly, thereby permitting an ejector mechanism to engage the innermost blank for dispensing same. However, due to the manner in which the hangers are shaped, the pads can also be mounted with the pad mounting member facing rearwardly. When this happens, the ejector mechanism can no longer engage the innermost blank, and thus the dispensing of blanks from the cabinet is physically impossible. Further, due to the carelessness of service personnel, this reversal in the mounting of the pads occurs with undesirable frequency, thus rendering the dispenser inoperative.
Accordingly, it is an object of the present invention to provide an improved dispenser which will prevent the improper mounting of the paper blanks therein. Particularly, the improved dispenseraccording to the present invention will permit the pads ofpaper blanks to be mounted in the dispenser in only one orientation relative to the dispenser, thereby insuring that the pads are always disposed in a position to permit the proper dispensing of the individual blanks.
A further object of the present invention is to provide a dispenser, as aforesaid, which has a pair of asymmetric hangers or support posts provided within the cabinet for supporting thereon one or more pads of blanks, which asymmetric hangers are designed to coact with suitable asymmetric openings formed in the pads to thereby positively prevent the pads from being mounted in the dispenser in a reversed manner.
These and other objects of the present invention will be apparent to persons acquainted with devices of this type upon reading the following specification and inspecting the accompanying drawings.

SUMMARY OF THE INVENTION The objects and purposes of the present invention are met by providing an improved dispenser which includes a cabinet having a back and a movable cover disposed for coaction with the back to define a closed chamber. The back of the cabinet is provided with a pair of hangers mounted adjacent the opposite upper comers thereof, which hangers coact with a pair of openings formed in the upper opposite corners of a mounting member or hanger board, which mounting member has a pad of folded paper blanks attached thereto. An ejector mechanism is movably mounted on the cover for permitting an individual paper blank to be severed from the pad and dispensed from the cabinet. The hangers according to the present invention are asymmetrical relative to the vertical centerline of the cabinet. The openings in the mounting member are also asymmetrical relative to the vertical centerline of the pad, whereby the pad can be slidably inserted on and supportedby the hangers only in one position in which the pad is properly oriented for permitting dispensing of the individualblanks.
DETAILED DESCRIPTION Considering now the drawings, there is illustrated a dispenser 11 for permitting paper blanks, particularly disposable toilet seat tissue covers, to be individually dispensed. The dispenser 11 includes a cabinet 12 which is mountable on a wall and supports therein a plurality of pads 13 of folded paper blanks or sheets. An ejector mechanism 14 is associated with the cabinet for permitting the paper blanks to be individually dispensed.
The cabinet 11 includes a back 16 which is fixedly secured, as by screws or the like, to a suitable wall or support surface. A cover 17 is hingedly connected to the back 16, as by hinge pins 18, and the upper edge of the back 16 is provided with a suitable lock member 19 thereon positioned to coact with the upper edge of the cover for maintaining the cover in a closed position substantially as illustrated in FIGS. 1 and 3.
The back 16 is provided with a pair of hangers 21 and 22 fixedly secured thereto adjacent the upper opposite corners, which hangers 21 and 22 support thereon one or more pads 13 in the space provided between the back 16 and the cover 17. Each of the pads 13 includes a plurality of tissue paper blanks 23 disposed in a stack, with the stack of blanks 23 being folded over substantially at their central portions so that the opposite ends of the blanks hang downwardly adjacent the lower portion of the cabinet as illustrated in FIG. 3. The stack of blanks 23 is secured, as by means of staples 24, to a mounting board 26. The mounting board 26 is often constructed of cardboard and is provided with suitable openings adjacent the upper corners thereof for engagement with the hangers 21 and 22. The individual pads 13 are each disposed within the cabinet so that the mounting board 26 is disposed adjacent the cover, with the stack of blanks 23 being positioned rearwardly of the mounting board. Further, the frontmost ends of the blanks 23 are provided with a central recess 27 formed therein, whereas the rearmost ends of the blanks 23 have a downwardly directed center flap 28. The flaps 28 are positioned so that they are individually engaged by the ejector mechanism 14 for permitting the centermost blank 23 to be individually dispensed downwardly through the discharge slot 29 which is formed adjacent and extends longitudinally along the lower edge of the cabinet 12.
The ejector mechanism 14 includes a slide member 31 (FIG. 4) slidably guided and disposed within the channel-shaped guide member 32 which is fixedly secured to the inner surface of the front wall of the cover 17. The guide member 32 has a pair of substantially parallel and opposed L-shaped rails 33 and 34 extending vertically along the opposite edges thereof, which rails 33 and 34 slidably guide and overlap the opposite edges of the slide member 31 for permitting same to be slidably vertically displaced. The spring 36 has one end thereof fixedly connected to the slide member 31 adjacent the lower end thereof, with the upper end of the spring 36 being secured to a stationary pin 37 mounted on the cover 17. Spring 36 normally resiliently urges the slide member 31 upwardly into engagement with a fixed stop 38.
The slide member 31 has an elongated tongue 41 mounted thereon, which tongue is disposed between the slide member 31 and the pads 13. The tongue 41 has the upper end thereof fixedly secured to the slide member 31, as by a rivet or screw 42. Tongue 41 is also provided with a hinge portion 43 disposed directly below the rivet 42 for enabling the tongue to be swingably moved about the hinge portion 43 in a direction substantially transverse to the plane of the slide mem- -ber 31. The lower end of the tongue is provided with a friction member 44 fixedly secured thereto, which friction member in the illustrated embodiment substantially comprises a semicylindrical member constructed of a plastic material and having a roughened or serrated surface for permitting frictional engagement with the downwardly extending flaps 28 of the blanks 23.
To permit actuation of the tongue 41 and of the slide 31, there is provided an actuator button 46 fixedly secured to the tongue 41 at a point disposed between the ends thereof. The actuator button 46 extends forwardly from the tongue and projects through a rectangular slot 47 formed in the slide member 31. The actuating button 46 also extends through a vertically elongated slot 48 formed in the guide member 32 and the front wall of cover 17, so that actuating button 46 thus extends outwardly beyond the front wall of the cover to permit same to be manually engaged. The button 46 is also slidably movable downwardly in the longitudinal direction of the slot 48, which in turn causes a corresponding downward movement of the slide 31 and tongue 41.
The structure of the cabinet 12, the pads 13 and the ejector mechanism 14 is substantially conventional and accordingly further description thereof is not believed necessary.
Considering now the structure of the hanger 21, as illustrated in detail in FIGS. 6-8, same includes a platelike mounting member 51 positioned directly adjacent and in engagement with the back 16 adjacent one of the upper corners thereof. The mounting member 51 is fixedly connected to the back 16 by means of a rivet or screw 52 extending through one of a plurality of openings 49 formed in the back 16. The mounting member 51 is also dimpled to form a rearwardly extending projection 53 which extends into still a further opening 49, whereby the rivet 52 and projection 53 thus fixedly and nonrotatably secure the mounting member 51 to the back 16.
The hanger 21 also has a substantially horizontally extending pin portion 54 which extends outwardly substantially perpendicularly from the back 16. The pin portion 54 extends in a direction toward the front wall of the cover 17 but terminates at a location spaced from the front wall. The pin portion 54 has a platelike horizontal leg portion 56 which is fixedly secured along one edge thereof to the lower end of a platelike vertical leg portion 57. The pin portion 54, as defined by leg portions 56 and 57, is thus substantially L-shaped in cross-section. The upper edge of the vertical leg por' tion 57 is formed with a reverse bend of approximately 180, thereby resulting in the formation of a downwardly opening arcuate portion 58 disposed on the op posite side of the vertical leg portion 57 from the horizontal leg portion 56. The vertical leg portion 57 has a vertical height adjacent the free end thereof which is greater than the vertical height adjacent the mounting member 51. This results in the upper surface 59 being disposed approximately horizontally but sloping slightly downwardly in a direction toward the back 16.
The pin portion 54 of the hanger 21 is adapted to slidably extend through a substantially L-shaped opening 61 formed in the upper comer of the mounting board 26, as illustrated in FIG. 8. The L-shaped opening 61 has a horizontally elongated slot portion 62 which communicates at one end thereof with the lower end of a vertically elongated slot portion 63. The vertical slot portion 63 is of sufficient height to accommodate therein the maximum vertical height of leg portion 57. However, as mounting board 26 is inserted over pin portion 54 and is slidably moved rearwardly toward the back 16, the decreasing vertical height of leg 57 generally results in the horizontal leg portion 56 engaging the upper edge of the horizontal slot portion 62 to thus provide the desired support for the pads 13.
The other hanger 22 is identical to the hanger 21 except that it is disposed adjacent the opposite upper corner of the back 16. The hanger 22 also includes a platelike horizontal leg portion 66 and a substantially vertical leg portion 67, whereupon the hanger 22 also has a substantially L-shape to permit it to slidably extend through a substantially L-shaped opening 69 formed in the opposite upper comer of the mounting member 26. Opening 69 also has a horizontally elongated slot portion 71 and a vertically elongated slot portion 72 to accommodate therein the leg portions 66 and 67. The hanger 22 thus cooperates with the opening 69 in substantially the same manner as the hanger 21 cooperates with the opening 61.
The hangers 21 and 22 and the openings 61 and 69, when viewed from the front as illustrated in FIG. 8, are identical in that the horizontal leg portions 57 and 66 of hangers 21 and 22, respectively, each extend laterally from their respective vertical leg portions in the same direction, namely leftwardly in FIG. 8. The hangers 21 and 22 are thus asymmetric relative to the vertical centerline of the cabinet. The L-shaped openings 61 and 69 formed in the mounting board 26 are likewise asymmetric relative to the vertical centerline of the pad IS in order to enact with the asymmetric hangers 21 and 22.
Further, the irregular or L-shaped cross-sections of the hangers 21 and 22 permit the hangers to be slidably insertable into the openings 61 and 62 only when the mounting board 26 is properly oriented relative to the cabinet. That is, the hangers 21 and 22 will slidably extend through their respective openings 61 and 69 only when the pad 13 is positioned so that the flaps 28 are disposed adjacent the rearward side of the cabinet. This thus prevents the pad 13 from being mounted in the cabinet in the reverse direction, namely with the mounting board disposed adjacent the back of the cabinet, since this reverse orientation of the pad will prevent the hangers 21 and 22 from being inserted through the openings 61 and 69. Thus, it is not possible to improperly position the pad within the cabinet.
OPERATION The operation of the device constructed according to the present invention will be briefly described to insure a more complete understanding thereof.
Briefly, when it is desired to load the cabinet 12 with the pads 13, the cover 14 will be pivotally swung downwardly into the open position illustrated in FIG. 2. When in this position, a pad 13 will be disposed so that the mounting board 26 faces outwardly, with the openings 61 and 69 adjacent the upper corners of the mounting boards being disposed adjacent the forward ends of the hangers 21 and 22. The mounting board will then be moved rearwardly so'that the L-shaped hangers slidably extend through the openings 61 and 69. Further, due to the asymmetric arrangement of the openings 61 and 69, and of the hangers 21 and 22, the pad 13 can be mounted on the hangers in only one orientation, thereby insuring that the pad 13 is properly positioned to permit proper dispensing of the individual blanks 23. Due to the rearwardly sloped upper surface 59, the pads will tend to slide rearwardly toward the back 16 and will thus be securely maintained on the hangers 21 and 22. Also, due to the length of the hangcrs, more than one pad 13 can be mounted on the hangers within the cabinet 12, as illustrated in FIG. 3. The cover 12 is then closed whereby the dispenser 11 is thus in an operation position to permit dispensing of individual blanks 23.
With the cover in the closed position, as illustrated in FIGS. 1 and 3, the slide 31 is normally urged into its uppermost position by the spring 36. Further, when in this position, the friction member 44 is disposed adjacent the recesses 27 formed in the lower ends of the blank 23, but is disposed so as to overlap the downwardly extending flaps 28. Thus, when an individual blank 23 is to be dispensed, the actuating button 46 will be manually pushed downwardly in the longitudinal direction of the slot 48. The downward pushing force imposed on the button 46 also causes the tongue 41 to pivot inwardly (clockwise in FIGS. 3 and-5) about the hinge 43, whereby the friction member 44 engages the flap 28 of the innermost blank 23. Further downward movement of button 46 causes the slide 31 and tongue 41 to move downwardly, whereupon the friction member 44, due to its frictional engagement with the flap 28, causes the innermost blank 23 to be severed from the pad and forcibly moved downwardly so that the lower edge of the blank 23 extends through the discharge slot 29, thereby permitting the discharged blank to be manually grasped and pulled downwardly to completely remove same from the dispenser 11. After the button 46 has been manually released, the spring 36 again moves the slide 31 and tongue 41 into the upper released position illustrated in FIG. 3, whereupon the device is thus in position to permit a further dispensing operation to be performed.
The structure of the present invention, due to the asymmetric hangers and openings, thus insures that the blanks are always positioned to permit proper dispensing thereof. This is important since, if the pad is accidentally suspended in the cabinet in an inverted manner, then the flaps 28 would be positioned adjacent the front side of the cabinet, whereupon the friction member'44 would thus engage the flap 28 of the outermost blank contained in the pad 13. In this situation, the outermost blank 23 cannot be dispensed, and accordingly, the dispenser 11 would be inoperative. This problem is thus totally overcome and eliminated by the use of the desirable hangers 21 and 22 and openings 61 and 69 as provided in the present invention.
It will be recognized that'the cabinet 12 and ejector mechanism 14 can assume many different shapes and configurations without departing from the essential concept of the present invention. For example, other such cabinet structures and dispensing mechanisms are disclosed in US. Pat. Nos. 2,931,536, 3,133,672 and 3,152,722, which patents are all owned by the Assignee of this application. Particularly, U.S. Pat. No. 3,133,672 discloses therein various modifications of the ejector mechanism, which modifications could be incorporated into the dispenser 11 of the present invention.
It will also be noted that the downward and rearward inclination of the upper surface 59 of the hangers reduces the possibility that the pads will accidentally fall off the hanger and also provides improved support for the pads.
Although a particular preferred embodiment of the invention has been disclosed in detail above for illustrative purposes, it will be recognized that variations or modifications of the disclosed apparatus, including the rearrangement of parts, lie within the scope of the present invention.
