Description
The present invention relates generally to novel package systems and particularly to a combination hand carried dispensing and unitary carton-shipping package system for industria1 size wipers.
At one time, virtually all industrial and shop wipers were assorted, odd-sized rags, sold typically in 25 pound bundles~ Oftimes, these 25 pound bundles contained poor quality rags having a variety of fluid absorbent characteristics which did not adequately meet users needs.
In an effort to provide an effective replacement 'or rags and other textile products, which would meet most of the needs of the users, many manufacturers of paper and synthetic products developed large size sheets of absorbent paper and synthetic material for use as wipers and towels which could be packaged and rapidly dispensed, providing the user a better wiper product than the aforementloned textile wipers.
Some manufacturers have provide~ large size disposable wipers e.g. 18 x 15 inches packaged in bundles of 50 wipers or in cartons of up to 200 wipers. The wiper material having qualities which compete with the strength;
bulk, durability and oil as well as wa~er absorbency as do textile products have been produced.
~5~2~
In preparing textile replacement products, manufacturers explored various techniques and methods for packaging their products. Some manufacturers prepared material in roll form for use in dispensers having a serrated cutter for cutting strips from the rollO Others packaged stacks of wipers in flat or folded sheet ~orm, in bands or cartons for distribution from dispensers. Still others formed continuous unitary tissue strips folded across its wid~h dimensions; each fold being in the alternate direction providing a zig-zag configuration containing perorations placed across its width dimension, at sequentially chosen locations, forming wiper segment regions. This folded and perfcrated strip is placed in a storage box. U. S~ Patent No. 3,490,645 dated January 20, 1970 of James Glass et al describes such a tissue strip.
Removal and separation of the tissue strips into wiper segments is accomplished by pulling a wiper strip out o~
the storage box through an opening therei~ and thereafter ~ detaching each individual segment from the strip along the perforations. To provide compact storage of the wiper strips, the material is usually folded longitudin~lly into C-folds or Z-folds.
Realizing problems such as the inconvenience of physically detaching each wiper along the perforations from wiper strips, a search for various other means to effec~
wiper dlspensing was initiated. This search resu]ted in the ; improved product of the present invention.
According to one aspect of the invention there is provided a dispensing system for dispensing wipers from a dispensing carton, the system having a subs-tantially continuous web of wiper material, of a predetermined length having disposed therein a plurality of transverse perforation lines disposed substantially equidistant to form a plurality of serially connected separable wipers within the web, each of the perforated lines including a plurality of perforated teeth and slits disposed in a particular sequence, at least one of the first and last slits in each perforation line extending to a side edge of the web, the seperable wipers being disposed in a stack in the carton. A dispensing port means is disposed in the carton for providing a port having a shape which permits detaching a leading separable wiper from the stack to yield a dispensed wiper. Detachment of the leading wiper from the trailing wiper is initiated by the at least one of the first and last slo-ts along the perforation line between the leading wiper and a trailing wiper straddling an edge of the port means. Following dispensing of the wiper, partial dispensing of the trailing separable wiper is effected so that dispensing and partial dispensing permits sequential dispensing of the stack of separable wipers.
According to another aspect of the present invention there is provided a method of making a zig-zag folded wiper dispensing system, the method including the steps of trans~
versely perforating a plurality of perforation lines spaced jrc:S ~
equidistant along a predetermined length of wiper material web to form a predetermined number of serially connected separable wipers, the perforation lines providing the separability characteristic of the web, each perforation line being comprised of a predetermined number of perforation teeth and slits spaced equidistant along the line with at least a one of the first and last slits extending into the respective edges of the web. Each of the separable wipers is trans-versely folded in the web in alternating opposite directions such that the folded segments are formed. A carton is formed for housing the folded web, the web being disposed in the carton such that each separable wiper is stacked upon the ne~t in a column. A removable elongated region is formed in a top panel of the carton, the region being of a given shape which, when removed, provides a dispensing port having an opening along a major axis of the top panel for the stack of separable -E~"` ' ~.~

The top panel provides a resistance to the trailing separable wiper of a magnitude which causes a last segment of the leading separable wiper to curl about the major axis of the port in a direction opposite to the direction which the first segmènt of the trailing separable wiper curls, causing the first and last perforation teeth along the perforation line to detach. The leading separable wiper is fur-ther advanced through the port so as to increase the magnitude of resistive force along the trailing separable wiper causing the remaining ~0 perforation teeth to detach effecting -the dispensing of a wiper and also to cause the first segment of the trailing separable wiper to protrude through the port and the remaining segments of the trailing separable wiper to partially unfold in alternating opposite directions providing a web structure which tends to resist fallback of the trailing separable wiper onto the stack.

-DETAlLED DESCRIPTION OF THE PREFERRED EI~ODIMENT
Referring to the drawing figures, there is sho~n in FIG. 1 a bloc~ diagram 10 which is illustrative of machinery used to prepare a stack of separable wipers suitable for use in this invention.
A continuous and bulky web 12, illustratively, of four-ply creped wadding material having a thickness of approximately 508 micrometers (20 mils~, a width of 38.10 cm (15 inches) and a length of at least 48058 meters ~1912.5 inches) is stored on storage reel 14. Web 12, which is fed from reel 14 into a conventional perforating device 16 is perfora~ed in a chosen manner to provide a plurality of transverse perforation lines 18-18 spaced equidistant along and transverse to the machine direction o~ web 12. (See FIG. 2.) Prior to the perforation operation, a plurality of equidistant lines are marked ~ transverse to the direction o web travel, illustratively every 48.58 meters (1912.5 inches) b~ a marking device 15 so as to provide an indication of enough footage of web material 12A for forming a stack of separable wipers.
In FIG. 2, there is shown~ as an elementary plan view of web 72A with lines 18-18 spaced at a chosen - interval transverse to the machine direction or longitudinal axis of the web. Illustratively, lines 18-18 are nominally spaced every 64.77 cm (25~ inches~. Also, each line 18 is comprised o a select number of p~rforation bonds ox teeth 18A-18A and perforated slits 18B-18B of a certain width and length respectively, disposed in a particular manner. Illustratively, line 18 comprises in th'e preferred embodiment elght (8) teeth which are 203 micrometers (8.0 mils) width and seven (7) slits which are 4.445 cm (1-3/4 inches) long; the two teeth at the extremities of line 18 are positioned inwardly from the edges of the web by approximately 1.27 cm (~ inch) leaving slits of approximately 2.223 cms (7/8 inch) ex,tending to the edges. These perforating teeth and slits are capable of being severed or broken in a controlled manner by means disclosed by this in~ention.
: Each marked and perforated web 12A is fed into a ' conventional web folding device 20 which is capable of folding the web into a plurality of individually folded separable wipers, each separable wiper being folded in alternating opposite directions to form a stack of separable wipers as illustrated in FIG. 3~ In the preferred embodiment each separable wiper is folded into 10.8 x 38.10 cm 14~ x 15 inches) units within the substantially continuous ~eb 12A, the perforation lines - 18-18 preventing the web from being a totally continuous web. Illustratively, each separable wipex is comprised of a first half-size segment l~D. Each group Of 75 folded but separable wipers in web 12A are manually detached along the marked line previously mentioned to form the stack of _ 9 separable wipers that is placed in each of the stoxa~e compartments ~f the carton and shipping package o~ this invention.
Means are provided in the carton and shipping package of this invention for dispensing individual wipers serially from the stack of separable wipers stored in the packaye. Referring now to FIGURE 4, there is shown the organization of a blank 30 of box material used in constructing the carton and shipping package o~ this invention. Tn the preferred embodiment, blank 30, fabricated from a die-cut blank of corrugated single-wall (or sometimes referred to as double-faced) box board, or other case-forming material, cut to a predetermined thic~ness, size, direction and contour, having proper ~ending ~ualities is employed. Illustratively, blank 30 has a nominal thickness of 0.318 cms (0.125 inch) and a nominal basis weight of 52.6 kg (116 pounds) per 6500 cm2 (1,000 square feet). The direction of the die-cut is such that flutes (f) of the corrugated fiberboard run parallel to the depth of the box, the side flutes being a B-flute construction of approximately 45 to 52 flutes per lineal foot~ Blank 30 comprises a partition panel 3~ with a 3.46 cm (1-3~8 inches) wide partition tab 34A attached to a first end of the panel 32 ~nd a pair of partition flaps 34B-34B attached ~o opposing ends. Panel 32 also has a perforated region 34C which when removed forms an aperture -- ].0 --~l15~
through ~Jhich the fingers of a hand may be extended; a - first bottom ~anel 36A with first partial inside flaps 38A-38A attached to opposing ends; a first side panel 40 with a pair of outside flaps 42-42 attached to opposing ends of panel 40; and a top panel 44 with full inside flaps 38B-38B attached to opposing ends, a second side panel 46 with a pair of outside flaps 42 att2ched to opposing ends and a second bottom panel 36B with a pair o second partial inside flaps 38C-38C attached to opposing ends.
Panel 44 also includes two elongated elliptically shaped perforated resions 44B-44B, which when removed, ~orm two side-by-side dispenser ports 44C-44C (best seen in FIG.
7). Dispenser ports 44C-4~C are used when dispensing the wipers from the stacks of wipers stored in the storage compartments of the package and are used in combination to form a hand opening for grasping a handle pan~l 44A used for hand carrying an open package.
Pursuant to a desirable feature of ~he invention, the size and shape of regions 44B-~4B are relaied to the width of web 12 and to the size of hand of an average man.
~s illustrated in FI&. 5 and its sub-figures SA SC, the length or major axis and width or minor axis of region 44B
are dictated by the diameter of the major and minor a~xiliary circles, respectively, of the ellipse which defines regions 44B-44B, centered at X=O, Y=O of the rectangular coordinates shown in FIG. SA. Other elongated , 115~
shapes may be used, however, but the elliptical shaped region has be~n chosen for use in the preferred embodiment.
The auxiliary circles are used as an aid in forming the ellipse. The length of the major a~is of the ellipse which corresponds to the diameter of the major auxiliary circle is so chosen to be shorter than the width o~ wiper 12A so that when a lead wiper is dispensed through port 44C a trailing wiper is partially pulled through port 44C and held about the circumference of port 44C by the retention forces caused basically by the length of the opening being substantially less than the width of the trailing wiper.
This retention and holding action of the trailing wiper makes possible the "pop-out" feature of this dispensing system.
The length of the minor axis of the ellipse which corresponds to the diameter of the minor auxiliary circle ~ is chosen to be substantially equivalent to the thickness of a fully-open hand of the a~erage man so that the average man may be able to insert his hand through port 44C to grasp a wiper on the top of the stack of wipers. For representative dimensions for forming the preferred emhodiment, the major auxiliary circle of the ellipse is 22.86 cm (9 inches) in diameter and the minor auxiliary circle is 7.62 cm (3 inches) in diameter.
To form the ellipse having major and minor axes corresponding to the diameters of the major and minor auxiliary circles respectively, several well-kno~m methods m~y be used, such as obtaining a preformed template of the precise slze or using analytical geometry or other plotting técnniques to plot arcs and- points which may be connected to form the shape.
Knowing the diameters of the major and minor auxiliary circles, represented by lengths AC and AB
respectively, in FIGo SB the coordinates of the foci can be determined. By using the well-known pythagorean theorem, which states the square of the hypotenuse of a right triangle equals the sum of the squares on the other sides, the length of CB which represents the distance between the oci fi-fi o~ FIG. SC of the ellipse may be calculated.
The coordinates of the ~oci along the major axis will be CB/2.
~aving the coordinates of the foci and knowing that elliptical curves are characterized by the fact that the sum of the distances from any point on the curve to the two foci is constant for that particular ellipse, the shape of tne ellipse having the chosen major and minor axes may be accurately traced b~ any of the aforementioned methods and disposed on top panel 44.
The perforated reaions 44~-44B are comprised o ~io different sizes of per.o-ation teeth and perforated slits, the slits being located between the teeth as illustrated in FIG. 5C at a reduced scale~ The smaller of ~.-15~
the two sets of perforation teeth and slits disposed along the arcs PP and QQ provide lines of weakness for inltlating removal of the regions 44B-44B as well as to lessen the tendency of tearing the outer facing covering the horizontal flutes or corrugations during completion of the removal operation. The larger teeth and slits are disposed along arcs PQ-PQ in order to minimize the loss of board strength of top panel 44 due to the perforations as well as to lessen the tendency of tearing the outer ~acing covering the horizontal flutes or corrugations during removal of regions 44B-44B. Both the small and large teeth are spac~d substantially equidistant along the arcs of the ellipse.
Representative dimensions used to form the preferred embodiment provides six (6) teeth along arcs PQ-PQ having widths of 0.397 cm (5/32 inch) and the remaining twenty-four (24) teeth along arcs PP and QQ having widths of 0.318 cm ~1/8 inch) with slits of 1.27 cm (~ inch in length) disposed equidistant between the teeth along the arcs. Additional perforations are disposed in regions D-D
in a manner perm-tting easy access to region 44B~44B.
Score line 48-48 of FIG. 4 are disposed so as to facilitate folding the cardboard panels, the bending along the score lines being such that the fiberboard is not ruptured to a point where it seriouslv weakens the box.
~eferring now to FIG. 6, there is shown an open-end view of an asse~bled paskage 31 formed from the .
~l~S~
one-piece blank of board material and two stacks of separable wipers. To assen~le package 31, blank 30 is folded along the designated score 48-48 starting with be~nding tab 34A and the fir:st bottom panel 36A with partial inside flaps 38A-38A.attached, in the direction shown to form partition 32. Then the first side pznel 40 with outside flaps 42-42 attached, top panel 44 with the full ins~de flaps 38B-38B attached, second side panel 46 with - outside flaps 42-42 ~ttached and the second bottom panel 36B with partial inside flaps 38C-38C attached are folded in the direction shown to shape the blank into an open carton format. Each.panel 34B-34B (not shown) are disposed to abut against a stack of separable wipers. Then partltion tab 34A is cemented to a longitudinal region E of top panel 44 ~ith a suitable glue in a manner disposing partition panel 32 to be equidistant from the two side panels 40 and 46, forming two adjacent wiper stack storage compartments 52 and 54 respectively. Following the act of Lorming the compartments, a free edge of second panel 36B
is overlapped and abutted against a first edge re~ion 50 of first bottom panel 36C and cemented to form a glued joint F
which extends to the partial inside flaps which depend Lrom the Lirst and second bottom panels. The inside flaps 38A, 38B and 38C, illustratively are 90 rectangular panels, ~hile outside flaps 42-42 are made to be substantially rectangular ln shape but the outer edge corners of ~laps 5~ 3 42-42 are oftimes slightly less than 90 corners to facilitake fo~ming smooth ends upon closure of the package 30. T~JO stacks of wipers, illustratively 150 wiper units/
7S wipers per stack are end-loaded into respective storage compartments 52 and 54 and the ~laps are closed and sealed with a conventional glue or in some instances with a conventional packaging adhesive tape forming the carton-packa~e shown in ~I~. 6A. The dispensing ports of package 31 is disposed at a height measured from the bottom of the carton which is approximately one half the lenqth of a wiper which is dispensed from the cartonr * * * * * * *
The operation of the package system will now be discussed. This svstem provides a combination unitary shipping package and a wiper dispensing hand carrying carton, the carton having a built-in carrying handle and a un~que "pop-out" dispensing feature tha~ allows the trailing wiper from the wiper stack to be partially - dispensed after the lezd wiper is dispensed.
Upon sealing the flaps closed, package 31 becomes a shipping package suitable for cargo shipment in interstate or intrastate commerce. The aforementioned perforation teeth configuration in the top panel 44 associated with regions 448-44B are disposed substantially in the same direction as the flu~es of the board material and provide suitable stren~th to the facing to enable this .
~.~L5~21 package to be used as a shipping package. Upon removal of the elliptical shaped perforated regions 44B-44B, the shipping package becomes a wiper dispenser carton having a pair of dispensing ports members 44C-44C. These port members also provide an opening or grasping the handle panel member 44A disposed in top panel 44.
Since dispensing of wipers from either storage compartment is identical, only one storage compartment and one dispensin~ port will be referred to hereinafter to describe the manner in which wipers are dispensed.
However, two storage compartments are used to provide stability to the package since a single stack of 75 sepzrab1e wipers would tend to tumble over. ~ithin the storage compartment the stack of separable wipers are of such a height and width that an initial air gap region G-G
of approximately 0.635 cm (~ inch) exists between the first wiper in the stack and the top panel. Also, there is approximately a 0.635 cm (~ inch) clearance between the stack and the partition, sidewall and the side flaps which form the storage compartment. To dispense the first wiper from the stack of separable wipers the dispensing procedure requires the extraction of the wiper from the storage compartment and then a separation of it from the stackO
The rirst half p~nel 12~ (best seen in FIG. 2) is grasped and pulled so 2S to cause the rem2ining five (5) folded panels 12C-12C and the other half panel 12D to unfold and ' .
bend to an elongated convergent~shape (best seen in FIG.7), as the panels pass through the dispensing port 44C of ~IG. 7. As the first s~iper is pulled further through port member 44C, the outer surface edge regions of panel 12D
bend about a portion of the elongated convergent-shaped opening forming a somewhat distorted "C" shaped wiper~
(See FIG. 8.) As the half panel 12D exists port me~ber 44C, the outer surface edge regions of the lead ~;per is released fro~ the curl condition and the edges of the two wipers juxtaposed to the first and last slits straddle the substantially curved boundary regions of port 44C 2S shown in FIG. 9. . .
: Also in this condition, the first and last perforation teeth of line 18 abut against the substantially curved boundary region of port member 44C. A5 further pulling force is e~Yerted on the leading wiper, the first - and last perforation teeth at the extremities o line 18 are severed automatically without being manually detached by a twisting action of the first half segment 12B of the trai'ing wiper which tends to twist in a direction opposite to that of the twisting action exerted ~n the other half segment 12D of the leading wiper. Once ~he outer extremity teeth are broken with the continuing pulling force being exerted on the leading wiper against the resistive Corces being exerted on the trailing wiper by the bottom face of panel 44, the frictional force caused by the arc ~oundary _ 18 -,
At one time, virtually all industrial and shop wipers were assorted, odd-sized rags, sold typically in 25 pound bundles~ Oftimes, these 25 pound bundles contained poor quality rags having a variety of fluid absorbent characteristics which did not adequately meet users needs.
In an effort to provide an effective replacement 'or rags and other textile products, which would meet most of the needs of the users, many manufacturers of paper and synthetic products developed large size sheets of absorbent paper and synthetic material for use as wipers and towels which could be packaged and rapidly dispensed, providing the user a better wiper product than the aforementloned textile wipers.
Some manufacturers have provide~ large size disposable wipers e.g. 18 x 15 inches packaged in bundles of 50 wipers or in cartons of up to 200 wipers. The wiper material having qualities which compete with the strength;
bulk, durability and oil as well as wa~er absorbency as do textile products have been produced.
~5~2~
In preparing textile replacement products, manufacturers explored various techniques and methods for packaging their products. Some manufacturers prepared material in roll form for use in dispensers having a serrated cutter for cutting strips from the rollO Others packaged stacks of wipers in flat or folded sheet ~orm, in bands or cartons for distribution from dispensers. Still others formed continuous unitary tissue strips folded across its wid~h dimensions; each fold being in the alternate direction providing a zig-zag configuration containing perorations placed across its width dimension, at sequentially chosen locations, forming wiper segment regions. This folded and perfcrated strip is placed in a storage box. U. S~ Patent No. 3,490,645 dated January 20, 1970 of James Glass et al describes such a tissue strip.
Removal and separation of the tissue strips into wiper segments is accomplished by pulling a wiper strip out o~
the storage box through an opening therei~ and thereafter ~ detaching each individual segment from the strip along the perforations. To provide compact storage of the wiper strips, the material is usually folded longitudin~lly into C-folds or Z-folds.

-DETAlLED DESCRIPTION OF THE PREFERRED EI~ODIMENT
Referring to the drawing figures, there is sho~n in FIG. 1 a bloc~ diagram 10 which is illustrative of machinery used to prepare a stack of separable wipers suitable for use in this invention.
A continuous and bulky web 12, illustratively, of four-ply creped wadding material having a thickness of approximately 508 micrometers (20 mils~, a width of 38.10 cm (15 inches) and a length of at least 48058 meters ~1912.5 inches) is stored on storage reel 14. Web 12, which is fed from reel 14 into a conventional perforating device 16 is perfora~ed in a chosen manner to provide a plurality of transverse perforation lines 18-18 spaced equidistant along and transverse to the machine direction o~ web 12. (See FIG. 2.) Prior to the perforation operation, a plurality of equidistant lines are marked ~ transverse to the direction o web travel, illustratively every 48.58 meters (1912.5 inches) b~ a marking device 15 so as to provide an indication of enough footage of web material 12A for forming a stack of separable wipers.
In FIG. 2, there is shown~ as an elementary plan view of web 72A with lines 18-18 spaced at a chosen - interval transverse to the machine direction or longitudinal axis of the web. Illustratively, lines 18-18 are nominally spaced every 64.77 cm (25~ inches~. Also, each line 18 is comprised o a select number of p~rforation bonds ox teeth 18A-18A and perforated slits 18B-18B of a certain width and length respectively, disposed in a particular manner. Illustratively, line 18 comprises in th'e preferred embodiment elght (8) teeth which are 203 micrometers (8.0 mils) width and seven (7) slits which are 4.445 cm (1-3/4 inches) long; the two teeth at the extremities of line 18 are positioned inwardly from the edges of the web by approximately 1.27 cm (~ inch) leaving slits of approximately 2.223 cms (7/8 inch) ex,tending to the edges. These perforating teeth and slits are capable of being severed or broken in a controlled manner by means disclosed by this in~ention.
: Each marked and perforated web 12A is fed into a ' conventional web folding device 20 which is capable of folding the web into a plurality of individually folded separable wipers, each separable wiper being folded in alternating opposite directions to form a stack of separable wipers as illustrated in FIG. 3~ In the preferred embodiment each separable wiper is folded into 10.8 x 38.10 cm 14~ x 15 inches) units within the substantially continuous ~eb 12A, the perforation lines - 18-18 preventing the web from being a totally continuous web. Illustratively, each separable wipex is comprised of a first half-size segment l~D. Each group Of 75 folded but separable wipers in web 12A are manually detached along the marked line previously mentioned to form the stack of _ 9 separable wipers that is placed in each of the stoxa~e compartments ~f the carton and shipping package o~ this invention.
Means are provided in the carton and shipping package of this invention for dispensing individual wipers serially from the stack of separable wipers stored in the packaye. Referring now to FIGURE 4, there is shown the organization of a blank 30 of box material used in constructing the carton and shipping package o~ this invention. Tn the preferred embodiment, blank 30, fabricated from a die-cut blank of corrugated single-wall (or sometimes referred to as double-faced) box board, or other case-forming material, cut to a predetermined thic~ness, size, direction and contour, having proper ~ending ~ualities is employed. Illustratively, blank 30 has a nominal thickness of 0.318 cms (0.125 inch) and a nominal basis weight of 52.6 kg (116 pounds) per 6500 cm2 (1,000 square feet). The direction of the die-cut is such that flutes (f) of the corrugated fiberboard run parallel to the depth of the box, the side flutes being a B-flute construction of approximately 45 to 52 flutes per lineal foot~ Blank 30 comprises a partition panel 3~ with a 3.46 cm (1-3~8 inches) wide partition tab 34A attached to a first end of the panel 32 ~nd a pair of partition flaps 34B-34B attached ~o opposing ends. Panel 32 also has a perforated region 34C which when removed forms an aperture -- ].0 --~l15~
through ~Jhich the fingers of a hand may be extended; a - first bottom ~anel 36A with first partial inside flaps 38A-38A attached to opposing ends; a first side panel 40 with a pair of outside flaps 42-42 attached to opposing ends of panel 40; and a top panel 44 with full inside flaps 38B-38B attached to opposing ends, a second side panel 46 with a pair of outside flaps 42 att2ched to opposing ends and a second bottom panel 36B with a pair o second partial inside flaps 38C-38C attached to opposing ends.
Panel 44 also includes two elongated elliptically shaped perforated resions 44B-44B, which when removed, ~orm two side-by-side dispenser ports 44C-44C (best seen in FIG.
7). Dispenser ports 44C-4~C are used when dispensing the wipers from the stacks of wipers stored in the storage compartments of the package and are used in combination to form a hand opening for grasping a handle pan~l 44A used for hand carrying an open package.
Pursuant to a desirable feature of ~he invention, the size and shape of regions 44B-~4B are relaied to the width of web 12 and to the size of hand of an average man.
~s illustrated in FI&. 5 and its sub-figures SA SC, the length or major axis and width or minor axis of region 44B
are dictated by the diameter of the major and minor a~xiliary circles, respectively, of the ellipse which defines regions 44B-44B, centered at X=O, Y=O of the rectangular coordinates shown in FIG. SA. Other elongated , 115~
shapes may be used, however, but the elliptical shaped region has be~n chosen for use in the preferred embodiment.
The auxiliary circles are used as an aid in forming the ellipse. The length of the major a~is of the ellipse which corresponds to the diameter of the major auxiliary circle is so chosen to be shorter than the width o~ wiper 12A so that when a lead wiper is dispensed through port 44C a trailing wiper is partially pulled through port 44C and held about the circumference of port 44C by the retention forces caused basically by the length of the opening being substantially less than the width of the trailing wiper.
This retention and holding action of the trailing wiper makes possible the "pop-out" feature of this dispensing system.
The length of the minor axis of the ellipse which corresponds to the diameter of the minor auxiliary circle ~ is chosen to be substantially equivalent to the thickness of a fully-open hand of the a~erage man so that the average man may be able to insert his hand through port 44C to grasp a wiper on the top of the stack of wipers. For representative dimensions for forming the preferred emhodiment, the major auxiliary circle of the ellipse is 22.86 cm (9 inches) in diameter and the minor auxiliary circle is 7.62 cm (3 inches) in diameter.
To form the ellipse having major and minor axes corresponding to the diameters of the major and minor auxiliary circles respectively, several well-kno~m methods m~y be used, such as obtaining a preformed template of the precise slze or using analytical geometry or other plotting técnniques to plot arcs and- points which may be connected to form the shape.
Knowing the diameters of the major and minor auxiliary circles, represented by lengths AC and AB
respectively, in FIGo SB the coordinates of the foci can be determined. By using the well-known pythagorean theorem, which states the square of the hypotenuse of a right triangle equals the sum of the squares on the other sides, the length of CB which represents the distance between the oci fi-fi o~ FIG. SC of the ellipse may be calculated.
The coordinates of the ~oci along the major axis will be CB/2.
~aving the coordinates of the foci and knowing that elliptical curves are characterized by the fact that the sum of the distances from any point on the curve to the two foci is constant for that particular ellipse, the shape of tne ellipse having the chosen major and minor axes may be accurately traced b~ any of the aforementioned methods and disposed on top panel 44.
The perforated reaions 44~-44B are comprised o ~io different sizes of per.o-ation teeth and perforated slits, the slits being located between the teeth as illustrated in FIG. 5C at a reduced scale~ The smaller of ~.-15~
the two sets of perforation teeth and slits disposed along the arcs PP and QQ provide lines of weakness for inltlating removal of the regions 44B-44B as well as to lessen the tendency of tearing the outer facing covering the horizontal flutes or corrugations during completion of the removal operation. The larger teeth and slits are disposed along arcs PQ-PQ in order to minimize the loss of board strength of top panel 44 due to the perforations as well as to lessen the tendency of tearing the outer ~acing covering the horizontal flutes or corrugations during removal of regions 44B-44B. Both the small and large teeth are spac~d substantially equidistant along the arcs of the ellipse.
Representative dimensions used to form the preferred embodiment provides six (6) teeth along arcs PQ-PQ having widths of 0.397 cm (5/32 inch) and the remaining twenty-four (24) teeth along arcs PP and QQ having widths of 0.318 cm ~1/8 inch) with slits of 1.27 cm (~ inch in length) disposed equidistant between the teeth along the arcs. Additional perforations are disposed in regions D-D
in a manner perm-tting easy access to region 44B~44B.
Score line 48-48 of FIG. 4 are disposed so as to facilitate folding the cardboard panels, the bending along the score lines being such that the fiberboard is not ruptured to a point where it seriouslv weakens the box.
~eferring now to FIG. 6, there is shown an open-end view of an asse~bled paskage 31 formed from the .
~l~S~
one-piece blank of board material and two stacks of separable wipers. To assen~le package 31, blank 30 is folded along the designated score 48-48 starting with be~nding tab 34A and the fir:st bottom panel 36A with partial inside flaps 38A-38A.attached, in the direction shown to form partition 32. Then the first side pznel 40 with outside flaps 42-42 attached, top panel 44 with the full ins~de flaps 38B-38B attached, second side panel 46 with - outside flaps 42-42 ~ttached and the second bottom panel 36B with partial inside flaps 38C-38C attached are folded in the direction shown to shape the blank into an open carton format. Each.panel 34B-34B (not shown) are disposed to abut against a stack of separable wipers. Then partltion tab 34A is cemented to a longitudinal region E of top panel 44 ~ith a suitable glue in a manner disposing partition panel 32 to be equidistant from the two side panels 40 and 46, forming two adjacent wiper stack storage compartments 52 and 54 respectively. Following the act of Lorming the compartments, a free edge of second panel 36B
is overlapped and abutted against a first edge re~ion 50 of first bottom panel 36C and cemented to form a glued joint F
which extends to the partial inside flaps which depend Lrom the Lirst and second bottom panels. The inside flaps 38A, 38B and 38C, illustratively are 90 rectangular panels, ~hile outside flaps 42-42 are made to be substantially rectangular ln shape but the outer edge corners of ~laps 5~ 3 42-42 are oftimes slightly less than 90 corners to facilitake fo~ming smooth ends upon closure of the package 30. T~JO stacks of wipers, illustratively 150 wiper units/
7S wipers per stack are end-loaded into respective storage compartments 52 and 54 and the ~laps are closed and sealed with a conventional glue or in some instances with a conventional packaging adhesive tape forming the carton-packa~e shown in ~I~. 6A. The dispensing ports of package 31 is disposed at a height measured from the bottom of the carton which is approximately one half the lenqth of a wiper which is dispensed from the cartonr * * * * * * *
The operation of the package system will now be discussed. This svstem provides a combination unitary shipping package and a wiper dispensing hand carrying carton, the carton having a built-in carrying handle and a un~que "pop-out" dispensing feature tha~ allows the trailing wiper from the wiper stack to be partially - dispensed after the lezd wiper is dispensed.
Upon sealing the flaps closed, package 31 becomes a shipping package suitable for cargo shipment in interstate or intrastate commerce. The aforementioned perforation teeth configuration in the top panel 44 associated with regions 448-44B are disposed substantially in the same direction as the flu~es of the board material and provide suitable stren~th to the facing to enable this .
~.~L5~21 package to be used as a shipping package. Upon removal of the elliptical shaped perforated regions 44B-44B, the shipping package becomes a wiper dispenser carton having a pair of dispensing ports members 44C-44C. These port members also provide an opening or grasping the handle panel member 44A disposed in top panel 44.
Since dispensing of wipers from either storage compartment is identical, only one storage compartment and one dispensin~ port will be referred to hereinafter to describe the manner in which wipers are dispensed.
However, two storage compartments are used to provide stability to the package since a single stack of 75 sepzrab1e wipers would tend to tumble over. ~ithin the storage compartment the stack of separable wipers are of such a height and width that an initial air gap region G-G
of approximately 0.635 cm (~ inch) exists between the first wiper in the stack and the top panel. Also, there is approximately a 0.635 cm (~ inch) clearance between the stack and the partition, sidewall and the side flaps which form the storage compartment. To dispense the first wiper from the stack of separable wipers the dispensing procedure requires the extraction of the wiper from the storage compartment and then a separation of it from the stackO
The rirst half p~nel 12~ (best seen in FIG. 2) is grasped and pulled so 2S to cause the rem2ining five (5) folded panels 12C-12C and the other half panel 12D to unfold and ' .
bend to an elongated convergent~shape (best seen in FIG.7), as the panels pass through the dispensing port 44C of ~IG. 7. As the first s~iper is pulled further through port member 44C, the outer surface edge regions of panel 12D
bend about a portion of the elongated convergent-shaped opening forming a somewhat distorted "C" shaped wiper~
(See FIG. 8.) As the half panel 12D exists port me~ber 44C, the outer surface edge regions of the lead ~;per is released fro~ the curl condition and the edges of the two wipers juxtaposed to the first and last slits straddle the substantially curved boundary regions of port 44C 2S shown in FIG. 9. . .
: Also in this condition, the first and last perforation teeth of line 18 abut against the substantially curved boundary region of port member 44C. A5 further pulling force is e~Yerted on the leading wiper, the first - and last perforation teeth at the extremities o line 18 are severed automatically without being manually detached by a twisting action of the first half segment 12B of the trai'ing wiper which tends to twist in a direction opposite to that of the twisting action exerted ~n the other half segment 12D of the leading wiper. Once ~he outer extremity teeth are broken with the continuing pulling force being exerted on the leading wiper against the resistive Corces being exerted on the trailing wiper by the bottom face of panel 44, the frictional force caused by the arc ~oundary _ 18 -,
2~L -.
: regions PQ of port member 44C as the traili~g wiper protrudes through port member 44C causes a force exceeding the tensile force to occur within the remaining interior perforation teeth which overcomes effectively the tensile force in the teeth resulting in a chain-type teeth breaking reaction across the transverse line 18 separating the leading wiper from the trailing wiper. Upon separation, the first half segment of the tr~iling wiper is held within the boundaries of the oval opening; the full segment o~ the wiper becomes partially unfolded to form expended zig-zag segments which are weakly indispensibly displaced from the hard fold format. .These ull segments extend from the port to the:top of the stack of separable wipers in a manner which tends to resist fall back of the trailing wiper onto the stack, see FIG. 10.
If the first and last teeth had been disposed at both e~tremities of the transverse line 18, this aforementioned separation sequence would probably not occur since neither outer ed~e of the trailing wiper unit would have been given a chance to abut against the bo-ttom face of .op panel 44 of the package. Also, if the teeth 11A-11A
along line 18 are not sized and spaced to present minimal resistance to breakage, the chain-t~pe teeth breaking reaction would be hindered, thus preventing the leading wiper from being separated from the stack of wipers.

Other fola configurations of separable wipers such as "V", "C" and "z" fold zig~zag may be used in this invention provided the perforation teeth and slits ar~
s~aced in the manner specified supra.
In the preferred embodiment as previously noted, the four-ply creped ~adding web was specified in order to provide high strength and good oil and water absorbency characteristics in the wiper. However, the web could be other materials such as nylon scrim reinforced tissue laminate or absorbent polyolefin of a thickness which can be perforated, ~olded in the alternating opposite directions and whi~h can be separated in the manner as delineated by the present invention~
