United States Patent 3,281,035 HAND-HELD CARTON DISPENSER George V. Woodling, 22077 W. Lake Road, Rocky River, Ohio Filed Sept. 20, 1965, Ser. No. 488,328 6 Claims. (Cl. 225-48) My invention relates to a hand-held carton dispenser having an elongated tear-edge means to facilitate an operation of tearing a sheet of material from the free end portion of a strip of material wound on a supply roll mounted within the carton dispenser.

When a sheet of material is torn from the free end portion of a strip of material wound on the supply roll, the tearing operation leaves a torn edge which constitutes the beginning of a next advanced free end portion. My invention particularly is useful in dispensing aluminum foil and other thin sheets of wrapping material, such as Waxed paper and polymeric film sheets, or a combination of these with aluminum foil. Preferably, my invention may be embodied in a hand-held carton dispenser made of paper-board. In this application, the new free end portion of the strip which presents itself after each sheet has been torn from the strip will be referred to as the next advanced free end portion.

There are many different types of hand-held carton dispensers on the market, but all of them have their shortcomings. In these hand-held dispensers, most attention has been directed to the ease with which the carton may be initially opened. On the other hand, very little attention has been given to the ease with which the strip of material may be dispensed into sheets after the carton is once opened. Each time a new sheet is dispensed, the housewife usually has to pick around in order to get hold of the next advanced free end portion of the strip for the next dispensing operation.

An object of my invention is the provision of a dispenser whereby the next advanced free end portion of the strip readily and automatically presents itself for easy grasping in starting the next dispensing operation.

Another object is to take advantage of the resilient tendencies and behavior of the strip of material being dispensed, as well as that of the paperboard from which the hand-held dispensers are made.

Another object is the provision of a dispenser by which nature aids in the dispensing operation rather than working against the operation.

Another object is to provide for stiffening or reinforcing the elongated dispensing edge of the carton dispenser to keep the elongated tear-edge means which is mounted therealong from bowing or flexing outwardly as a sheet of material is being torn off.

Another object is to provide for mounting the elongated tear-edge means along an elongated foldable dispensing edge of double thickness formed by folding two adjacent carton panels in face-to-face relationship about an elongated common hinge-joint, hingedly connecting said panels together.

Another object is to provide for mounting the elongated tear-edge means on an inside panel surface of the carton dispenser along an elongated foldable dispensing edge of double thickness formed by folding two adjacent carton panels in face-to-face relationship about an elongated common hinge-corner hingedly connecting said panels together.

Another object is to provide for mounting the elongated tear-edge means on an outside panel surface of the carton dispenser along an elongated folda-ble dispensing edge of double thickness formed by folding two adjacent carton panels in face-to-face relationship about an elongated common hinge-joint, hingedly connecting said panels together.

Another object is to provide for mounting the elongated tear-edge means along an elongated foldable dispensing edge of double thickness formed by reversibly folding the lid panel of the carton dispenser in face-toface relationship to the rear panel about an elongated common hinge-corner, hingedly connecting said lid panel and said rear panel together.

Another object is to provide for mounting the elongated tear-edge means along an elongated common hingejoint, hingedly connecting two adjacent carton panels together, the elongated tear-edge means being mounted on either one of the two adjacent carton panels and on either the inside or outside of the carton.

Another object is to provide for mounting the elongated tear-edge means along an elongated common hingecorner, hingedly connecting two adjacent carton panels together, the elongated tear-edge means being mounted on either one of the two adjacent carton panels and on either the inside or the outside of the carton.

Other objects and a fuller understanding of the invention may be had by referring to the following description and claims, taken in conjunction with the accompanying drawings in which:

With reference to the drawings, my hand-held carton dispenser comprises substantially an elongated square box having an elongated front panel 21, a rear panel 22, and a bottom panel 23. The end panels of the box are identified by the

reference characters

24 and 25, respectively. The top peripheral edge of the elongated box defines an elongated opening through which the supply roll is mounted in the box and from which the free end portion of the supply roll is withdrawn. The opening is adapted to be closed by a lid panel 26 having a flange panel 27 disposed (spot-glued) against the outer surface of the front panel 21 to facilitate easy opening of the box. The glue spots are identified by the reference character 28.

The lid panel 26 and the flange panel 27 are hingedly connected together along a score or crease line 30 which when folded becomes an elongated common hinge-corner 30. Also, the lid panel 26 and the rear panel 22 are hingedly connected together along a score or crease line 31 which when folded becomes an elongated common hinge-corner 31. In FIGURE 3, the score or crease lines which form the corners of the box are shown by dot-dash lines, except 31 which is covered by a tear-strip 42.

The

end panels

24 and 25 of the box are identically constructed and each comprises two inside

end flaps

32 and 33 and an outside end flap 34, all being folded and glued together. The outside end flap 34 is provided with a top marginal edge portion 35 which is folded over the top of the

inside flaps

32 and 33 where it then may extend as a short flange flap into the box above the supply roll. As an alternative, the top marginal edge portion 35 may be .glued to the top marginal edges of the inside flaps to form sturdy top foldable edges for supporting the end portions of the lid panel when closed. The construction of the box thus far described is rather common,

The foil or other sheet material which is to be dispensed is wound on a hollow supply roll 36. As the free end portion of the strip of material is withdrawn from the box, the supply roll 36 is caused to unwind by rotating within the box. It is preferably to stabilize the supply roll within the box as it is being unwound. For this purpose, the inside flaps 32 and 33 are respectively provided with hinged

tabs

40 and 41 which are disposed to extend into the open ends of the hollow supply roll, see FIGURES 48. The hinged

tabs

40 and 41 stabilize the supply roll within the box by keeping the supply roll from elevating itself within the box when the free end portion of the strip of material is being withdrawn from the roll.

The elongated tear-edge means is identified by the reference character 42 and preferably comprises an elon gated thin metal strip having first and second opposite elongated marginal edge tear-

teeth

43 and 44 defining the width thereof, see FIGURES 3 and 10. For economical manufacture, both edges of the metal strip are provided with tear-teeth, although only one edge is used in the tearing operation. The elongated tear-edge means 42 is preferably mounted upon the underneath side of the lid panel next adjacent the inside hinge-corner 31, see FIG-

URES

2, 3, 4 and 7. The score or crease line 31 which forms the hinge-corner 31, as well as the score or crease lines for all other hinge-corners or joints, is made during the manufacture of the box. In the manufacture, the score or crease lines on one side of the paperboard comprise elongated depressed grooves 45 and the score or crease lines on the other side comprise elongated complementary out-pressed ridges 46, see FIGURES 9 and 10. In FIGURE 11, the score or crease lines 31 is folded into the hinge-corner 31 with the out-pressed ridge forming the inside of the corner and the depressed groove forming the outside of the corner. In all instances where the cross-section of the paperboard blank is too small to show the depressed grooves and the complementary out-pressed ridges, it is to be understood that they nevertheless are present the same as shown in FIGURES 9 and 10. The elongated out-pressed ridge 46 constitutes an automatic marker for locating the elongated tear-edge means 42. As shown in FIGURES 10 and 11, the elongated tearedge means 42 is secured to the underneath side of the lid panel 26 by means of integrally formed staples 47 and is so aligned with respect to the out-pressed ridge 46 that the tear-teeth 43 extend beyond the top of the ridge to a place substantially above the juncture 48 where the ridge meets with the plane of the lid panel. By so locating the tear-teeth 43, they are caused to abut against the inside wall surface of the rear panel 22 when the lid panel 26 is actuated to its closed position, :see FIGURE 11. Now, when the lid panel 26 is reversibly folded to a reverse dispensing position, as shown in FIGURES 5 and 12, with its outer surface folded face-to-face against the outer surface of the rear panel 22, the tear-teeth 43 are caused to project slightly above the elongated foldable dispensing edge 49 so formed by such reverse folding, see FIGURE 12. When the elongated tear-edge'means 42 is so located with reference to the out-pressed ridge 45, the tear-teeth 43 are ideally situated for the operation of tearing a sheet of material thereacross. In addition, the double-panel thickness, provided by the lid panel 26 being folded against the rear panel 22, reinforces or stiffens the foldable dispensing edge 49 and keeps it from bowing or flexing outwardly as a sheet of material is torn across the tear-edge means. This reinforcement greatly improves the tearing operation.

FIGURE 13 is similar to FIGURE 12 except that the tear-edge means is mounted on the inner surface of the rear panel 22 instead of on the underneath surface of the lid panel as shown in FIGURE 4. Thus, in FIGURE 13, the tear-edge means 42 is on the inside of the box whereas in FIGURE 12, the tear-edge means is on the outside of the box. Both mountings work equally well.

' The dispensing operation may be explained with reference to FIGURES 4 to 8, inclusive. The FIGURE 4 shows the condition of the carton dispenser as it is shipped before it is used. In opening the carton dispenser, the flange panel 27 is first separated from the front panel 21 by pulling outwardly on same until all the glue spots 28 are broken, after which the lid panel 26 and the flange panel 27 are reversibly folded respectively against the outer surface of the rear panel 22 and of the bottom panel 23, see FIGURE 5. The free end portion of the strip of material is next withdrawn from the supply roll with the withdrawn strip preferably leaving the supply roll from the top thereof. When a suflicient amount has been withdrawn, it may then be severed by tearing same across the elongated tear-edge means 42. The tearing operation is clean-cut because the foldable dispensing edge 49 is rein forced by the double thickness of the lid panel and the rear panel being folded against each other. During the tearing operation, the housewife (assuming that she is right-handed) will naturally want to hold the carton dispenser with her left-hand while she tea-rs the strip of material with her right hand. When holding the carton dispenser with her left hand, she will naturally apply pressure against the front panel 21, causing it to flex or bend inwardly against the supply roll. This squeezing action tends to arrest the rotation of the supply roll when the tearing operation is being performed, see FIGURE 5. When a sheet has been torn from the free end portion of the supply roll, the next advanced free end portion will automatically swing upwardly due to the resiliency of the material and assume a position above the supply roll as shown in FIGURE 6.

After the tearing operation is finished, the housewife then simply closes the lid panel 26 by inserting the flange panel 27 inside the box next adjacent the inner surface of the front panel 21, see FIGURE 7. The closed box may now be stored in a cupboard or on a shelf until the housewife is ready to use the carton dispenser again, whereupon she reversibly folds the lid panel 26 and the flange panel 27 respectively against the rear panel 22 and the bottom panel 23, see FIGURE 8. When the lid panel is lifted, the next advanced free end portion of the strip of material will automatically swing upwardly as shown in FIGURE 8, where it may be easily grasped for starting the next dispensing operation. The housewife in grasping the next advanced free end portion of the strip of material will normally want to hold the carton dispenser in a tilted position, as shown in FIGURE 8, where it is rotated to a counter-clockwise position about fifteen degrees from the horizontal. This tilted position will tend to make the next advanced free end portion of the strip of material swing upwardly where it may be easily grasped for starting the next dispensing operation. For a left-handed person, the operation is the same except that the carton dispenser is held in the right hand while the left hand grasps the next advanced free end portion of the strip of material for completing the tearing operation.

In the above description of the dispensing operation, the free end portion of the strip of material was preferably withdrawn from the top of the supply roll. As an alternative, the free end portion of the strip of material may be withdrawn from that side of the supply roll which is next adjacent to the dispensing edge as shown in FIGURE 12.

A modification of the invention is shown in FIGURES 14-19. In these figures, a truss panel 70 has been added. As illustrated, the truss panel is folded inside the box next adjacent the supply roll and is hingedly connected along a common hinge-joint 71 to the top edge of the front panel 21, see FIGURE 15. In this View, the tear-edge for a tear-strip 73 is identified by the reference character 71. This same reference character is used to identify the common hinge-joint since the two coincide with each other. The construction of the modified box is the same as that shown in FIGURES 1-8 and corresponding parts are designated by the same reference characters. FIG- URE 16 shows the free end portion of the strip of material leaving the supply roll on that side of the supply roll next adjacent the truss panel 70. The truss panel 70, when folded inside the box as shown, provides a double thickness to the dispensing edge. The tear-edge means, now identified by the reference character 73 is mounted on the outside surface of the front panel 21. The resiliency of the reverse fold at the dispensing edge causes the truss panel 70 to swing against the side of the supply roll. The truss panel 70 stabilizes the dispensing edge and keeps the tear-edge means from bowing or flexing outwardly during the tearing operation. For easy dispensing in FIGURE 16, the strip of material is pulled out a couple of inches after which the flange panel 27 is tucked in against the backside of thewithdrawn strip, as shown in FIGURE 18. The free end of the withdrawn strip of material is now drawn out to the desired length with the lid panel closed. The withdrawn strip may now be torn off, after which the box with the lid panel 26 still closed may be stored on a shelf or in a cupboard until ready for reuse. In the next dispensing operation, when the operator lifts the lid panel 26 and thereby withdraws the flange panel 27, the free end portion of the strip of material will ordinarily swing away from the truss panel 70', as shown by the dotted line 74 in FIGURE 18. The strip, in the position of the dotted line 74, may be easily grasped for starting the next dispensing operation. The applicant has discovered that the free end portion of the strip of material will ordinarily swing away from the tear-edge means, as shown by the dotted line 74 when a truss panel is used. In FIGURE 19, the free end portion of the strip of material is withdrawn from the top of the roll as shown in FIGURE 5.

In the present invention, the dispensing edge is partly rendered stiff and sturdy by reason of the double thickness resulting from the folding of two adjacent panels with respect to each other. In the case of the dispensing edge in FIGURES 5, 6 and 8, this stiffness is further augmented by reason of the fact that the flange panel 27 is hooked or folded under the bottom panel 23. The juxtaposition of the panels causes the lid panel 26 to function as a truss panel for reinforcing the elongated dispensing edge.

The hooking of the folded flange panel 27 under the bottom panel 23 makes the truss effect of the lid panel 26 all the more pronounced, to the end that the elongated dispensing edge is rendered extra stiff. A truss is usually in the form of a triangle, such as the truss panel 70 in FIGURES 1619. However, the hooked flange panel 27 under the bottom panel appears to give a corresponding triangular effect and thus in this application the lid panel 26 in its reversibly folded position may properly be characterized as a truss panel.

In the case of the dispensing edge in FIGURES 16-19, this stiffness is further augmented by reason of the fact that the truss panel 70 is disposed at an angle to the front panel 21 and functions as a brace to reinforce the dispensing edge. In both embodiments, the dispensing edge, due to the truss panels, is rendered rather still as compared to that afforded by a panel of single thickness. The added stiffness plays a part in producing an easier tearing operation.

The present disclosure includes that contained in appended claims as well as that of the foregoing description.

Although this invention has been described in its preferred form with a certain degree of particularity, it is 'understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
