INVENTOR ALLEN C. HARRIMAN Y Wl/Wj T PAIENTEUJAN 81973 3.709.403 SHEET 3 0F 3 INVENTOR ALLEN C. HARRIMAN WEB CARRIED TOOTHPICK DISPENSER SUMMARY OF THE INVENTION Conventionally, toothpicks have been made available, loosely and unwrapped, in a tray or dish for the convenience of the patrons of clubs, hotels and restaurants. There have also been devices in which unwrapped toothpicks have been dispensed from small hopper-type units suitable for use on counters and tables. More recently, wrapped toothpicks have begun to take the place of the unwrapped toothpicks, but still dispensed loosely as separate packages from an open tray or dish.

In accordance with the present invention, an automatic dispenser for wrapped toothpicks is provided wherein a long continuous web of spaced wrapped toothpicks (singles or pairs) may be contained within a compact and convenient dispensing unit from which the sealed toothpick package units may be taken from the dispenser one at a time while at the same time advancing the web to delivery position for the next sealed toothpick package. Simple but effective automaticallyoperating means insures proper detachment of each sealed toothpick package from the web.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an oblique view of the dispenser.

FIG. 2 shows a portion of the supply web of spaced, wrapped toothpicks.

FIG. 3 is a sectional detail of one type of supply web, showing on an enlarged scale a separated section of the web with a single toothpick sealed therein.

FIG. 3A is a sectional detail view of another form of supply web, showing a detached toothpick package containing a pair of toothpicks sealed therein.

FIG. 4 is a front view of the dispenser on a somewhat enlarged scale partly in section with the front wall broken away to show interior mechanism in front elevation.

FIG. 5 is a sectional view taken on the line 5-5 of FIG. 4 but including the front wall of the dispenser, showing a top view of the operating mechanism. A portion of the toothpick shown in this view has been broken away for the purpose of clarifying the sectional views of FIGS. 6, 7 and 8.

FIGS. 6, 7 and 8 are sectional views taken on the line 6--6 of FIG. 5, showing in side elevation the operating mechanism and its sequence of positions in the dispensing of wrapped toothpicks fromthe supply web.

DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION As best shown in FIG. 1, the dispenser is provided with parallel spaced side walls 12 and 14 to which cover 16 is pivotally attached at 17. The dispenser also includes a sloping front wall 18 having a central slot or opening 20 at which the toothpicks are presented for delivery. The front wall encloses only the upper portion of the front of the dispenser so as to leave a relatively clear open space below the front wall for a person to reach in with his fingers to grasp and remove a wrapped toothpick package visible within the delivery opening 20. To prevent marring the surface of a counter top or table, the lower edges of the side walls are provided with non-metallic channel strips 22. The side walls are held in spaced relation by a cross-member 24 just above the protective edge pieces, and by the front wall 18 whose side flanges 26 overlie and are secured to the side walls.

Within the dispenser, means are provided for rotatably supporting a roll 30 containing toothpicks 32 in parallel spaced relation transversely of a web 34 composed of two strips of thin protective material between which the toothpicks are: sealed. FIG. 3 shows in enlarged sectional detail a single toothpick within the protective enclosing material that forms the sealing enclosure as well as the carrier web, while FIG. 3A shows a package in which two toothpicks are sealed.

To facilitate the separation of wrapped toothpicks from the web without breaking open the protective wrapping, the web as part of the manufacturing process is partially severed between tooth-picks, as shown at 35 in FIG. 2, leaving pairs of short unsevered portions 36 to maintain continuity of the web for packing, shipping, and dispensing most effectively from the supply. The web is preferably although not necessarily arranged in a roll as shown, and is conveniently supported in centerless fashion on bottom member 24 between oblique plates 42 secured to the walls of the casing.

From the supply roll the web passes over a roller 44 near the top of the front wall and then downwardly along the rear of the wall, as best shown in FIGS. 6, 7 and 8. To position the web during its advance to the delivery aperture 20, guiding means are provided which are illustrated in FIGS. 4 and 5. Members 50, disposed on each side of the delivery aperture, are spaced from the rear surface of the front wall member 18 a distance to accommodate the outer, tapered end portions of the toothpicks and the web margins projecting beyond. To provide clearance for the effective operation of the trigger mechanism to be described, the front wall of the dispenser has a forwardly offset central region 52 (see top sectional view, FIG. 5). The guide members 50 advantageously are in the form of channel members whose outer flanges 54 serve to support the guide members from the side walls 12 and 14 by the same rivets 55 which secure the flanges 26 of the front wall member.

As has been indicated, a feature of the invention resides in the provision of means by which the removal of a toothpick package from the delivery point serves to advance the web the correct distance to render the following package accessible at the delivery point, while causing the web to be severed to release the first toothpick unit withprotective covering intact. To accomplish the foregoing, a trip or trigger device is mounted behind the web in the vicinity of the delivery opening so as to be actuated by and to act upon the web and its contents during the .web advance.

The trigger device comprises a pair of spaced bars 60 pivotally mounted on separate shafts 62 and 63 extend ing through the outer and inner flanges 54 and 64 of the guide members 50. Cotter pins 66 inwardly of the flanges 64 prevent the shafts from sliding out of position in their supporting flanges. The inner ends of the shafts terminate just inside the bars 60 to provide an open region behind the toothpicks in the delivery opening 20. At the ends of the bars remote from the delivery opening, they are joined by a connecting member 70 which may be formed of a solid rod! of metal which also serves as a weight tending to rock the bars 60 in a counterclockwise direction as viewed in FIGS. 6, 7 and 8. A stop pin 72 limits the clockwise rocking movement to a predetermined amount.

The forward ends of the trigger bars 60 extend into the path of the toothpicks in their advance down the guideway. The portions of the bars that are engaged indirectly by the toothpicks within the web are the end surfaces 76 in the lower end region of the bars and the top corners 78. The upper end regions of the bars below the corners 78 may have oblique surfaces 80 to form a shallow notch or recess terminating in a sloping shoulder or ledge 82.

In the operation of the dispenser, it is first loaded with a supply roll of toothpicks by opening the cover 16 and placing the roll on cross-member 24 between the plates 42. The lead end of the web is then pulled from the supply roll, brought over the roller 44 and fed downwardly into the guideway toward the delivery opening. When the first wrapped toothpick package reaches a visible position within the opening, the dispenser is ready for use and the cover may be closed.

The partsare now in the position shown in FIG. 6, with the trigger bars resting at the limit of their counterclockwise rocking movement as a result of engagement of their lower corners 86 with the rear surface of the guideway formed by the region 52 of the front wall (note also FIG. This places the shoulder region 82 in the path of the toothpick. When a person wishes to take a wrapped toothpick from the dispenser, he may readily reach into the opening and grip with his fingers the central portion of the web containing the leading toothpick and follow with a downward pull. As the web moves downwardly, the leading toothpick comes into engagement (in effect, since the web is still intact over and around the toothpick) with the shoulders 82 on the trigger bars to tilt them to the position shown in FIG. 7. In this position, which is maintained by engagement of the leading toothpick with the end surfaces 76 as it moves down the guideway, the upper corners 78 are caused to extend into the path of the preceeding toothpick.

Continued downward advance of the web now causes the second toothpick to engage the top ends of the trigger bars and rock the bars to the limit of their clockwise rotation, defined by engagement of stop pin 72 with the edge of flange 64. With the guideway passage effectively closed off by the close approach of corners 78 to the guideway surface rearwardly of region 52, further downward advance of the web is thereby prevented, as shown in FIG. 8. The web thereupon separates at the narrow connecting regions 36 to release the first toothpick package with its wrapper intact. As soon as the web severs, the weight 70 drops to raise the forward ends of the trigger bars to their open position of FIG. 6, with the preceeding toothpick package still connected to the supply web, now in accessible position within the opening 20.

While the invention has been described in terms ofa supply web in which a single toothpick is enclosed in each web portion between lines of severance, the supply web may readily be formed with pairs of toothpicks sealed within each web section and dispensed in the same manner as described for the singly-wrapped toothpicks.

With either type of supply web, the mechanism shown and described permits a large supply of wrapped toothpicks to be dispensed from a continuous web from which individual packages may be successively detached with their toothpicks still sealed in their particular section of the web, with the step-wise feeding of the web occurring automatically with each withdrawal of a toothpick-containing web section from the access opening.
