It is well known that many people preer to use inexpensive, disposable paper or plastic bags as a - ;~
substitute for the conventional cloth or other type re~
useable materials for various applications. For example, film and sheet materials made from various plastic polymers, such as polyethylene, polyvinyl chloride, polyesters and the like are enjoying wide popularity for applicatlon~
normally reserved for reuseable materials. These ~ ~ ;
materials, even in their ilm form, are strong, sanitary and relatively inexpensive which lends them well for use as a packaging medium. Consequently, some of the most important uses of plastic Eilm are in the ~ ;

: , .
~ 0 ~ 7 ~ 0 ~
production of wrapper~ for food ~uch as ~andwich bags, lunch bags, food storage bags and the like. Numerous other important uses have been made of plastic film as 9 for example, in trash collectlon such as wastebasket bags, trash bags and the like, and in dry cleaning stores to cover cleaned sults or dressesl Generally, the latter type plastic bags have been assembled on large dlspensing rolls on cores in such a manner that the individual bags are ~oined to each other along perforated lines ~hat can be ~ .
relatively easily severed to separate one outermost bag from the roll. However, these rolls are usually large and cumbersome to handle.
For household use, large-size bags are usually folded into rectangles and superimposed one on top of .
the other whereupon the bag assembly is then placed in a rectangular dispensing carton. Acce~s to the bags in ;;~
this type of package arrangemen~ is u~ually through an opening in the front and/or top face of the carton. One of the dlsadvantages of this packaglng technique is that each bag i8 usually folded upon itself seve~al ~ime~ and thu~ when the bag i~ removed from the carton, it is ;~
quite wkward to unfold.
U. S. Patent 3,826,361 discloses another technique for packaging l~rge-size bags which comprise arranging a plurality of folded bags in an overlapping sequence in the direction of the fold line~, rolling the overlapped ::

bag is pulled off the roll. This type of packaging technique requires a rather large size carton to ~llow rotation of the rolled bag assembly to facilitate the .
peeling off of the outermost wound bag.

SUMMARY OF TH~ INVENTION
The invention broadly relates to a bag dispenser package c~mprising a plurality of separate and discrete bags, each bag comprising open and closed opposite :~:
ends, front and back walls and closed lateral sides;
all of said bag~ being arranged in a sequential alignment and rolled to form a generally cylindrically shaped coreless roll; a container dimensioned to contain ~aid coreless roll; and means for providing an opening in said container proximal the a~is of the cylindrical roll .~ ;--: , through which the innermost wound bag at the center of .. ~.
the roll can be pulled out from said roll. Preferably, .
the bags comprising the roll should be arranged and aligned in an overlapping or interleaved sequence so .. ~
that the removal of the innermost wound bag will carry ` ;
with it the leading edge of the succeeding innermost :.,, ,. :
. wound bag thereby positioning said edge of the succeeding innermost wound bag through the opening in the container. .
As used herein, the term "generally cylindrically .. . .
20 ~ shaped corelexs roll" shall mean anything between a ~. :
truly cylindrically shaped roll and a cylindrically shaped roll that has been flattened so as to forn an `.
ovally shaped roll.
:: , . ..
As used herein, the term "interleaved sequence" .. - m~
shall mean a sequence of transverYely folded bags wherein ;~.
each bag forms a "V" shaped configuration with the folded or common edge designated as the leading edge and the .
'. '. '., .. . . . .
opposite and~eparate edges designated as the traillng edges and wherein the leading edge o~ one bag is inserted between the trailing edges of a preceding transver~ely olded bag with the leading edge of said preceding bag~`
inserted between the trailing edges of the nex~ preceding bag arld 80 Gn in sequence.
The term "folded bag" ~hall mean a bag that has been folded at least once in any manner9 preferably longi~
tudinally andlor transversely, prior to being rolled.
In rolling the bags into a cylindrically shaped roll, care should be exercised to maintain a space or ~ -opening at the axis of the roll so that the first inner-most bag can be grasped and removed from the roll without -~
~oo much difficulty. It has been found that an axiaI
hole having a diameter between about 0.75 inch (1.905 cm) and about 2.5 lnches (6.35 cm) will be suitable for most applications, while a diameter larger than about , : . .
2.5 inche~ (6~35 cm) may be suitable for large size rolIs ;;
intended for industrial or institutional use. An axial hole diameter between about 1 inch (2.54 cm) and 1~75 inches ~4.45 cm) is preferred for rolls intended for household use.
In one embodiment, the separate and discrete bags, folded or unfolded9 could be aligned such that the ~ ~i open or closed end of the first bag would be ad~acent ~ ~`
the closed or open end, respectively~ of the next sequenced bag so that when the bags are rolled, the removal of 8.
~ ~ 47 ~ 0 the innermost wound bag will not carry with it the suc-ceeding innermost wound bag.
In another embodiment, separate and discrete bags, folded or unfolded, could be folded or further folded transversely and the folded or leading edge interleaved into the trailing edges of an adjacent transversely folded bag.
In this embodiment, removal of the innermost bag from the ~ ` -roll will carry with it the next innermost bag. ~ ~;
In ànother embodiment, the separate and discrete ~ . ~
bags, folded or unfolded, could be aligned in an overlapping or shingled sequence so that when the bags are rolled, the removal of the innermost wound bag will carry with it the succeeding innermost wound bag.
The overlapped or interleaved length of the bags, -i.e. the length of the common surface area be~ween adjacent bags, will depend upon the initial diameter of the hollow ;
core of the roll, the number of bags in the roll, the number ;~
of folds in an overlapped or interleaved bag, and also depends upon whether the bags are to be dispensed from the . .
bag dispenser package in a direction oriented horizontally, vertically upward, vertically downward, downwardly inclined or upwardly inclined. ~;
For most applications of the overlapped or inter- -~
leaved roll assembly, the overlapped or interleaved length of the bags, could be between about 2 inches t5.08 cm) and -~
about 9 inches (22.86 cm). An overlapped or interleaved length generally less than 2 inches (5.08 cm) would be undesirable because the leading edge of a succeeding bag may not be withdrawn through the opening when the roll of bags was nearly spent while an overlapped length . . : , . .
10470~2 generally greater than 9 inches (22.86 cm) would be un~
suitable because too long a portion of the succeeding ; ;
bag length may be withdrawn or carried with the bag being dispensed.
Pre~erably, this overlapped or in~erlea~ed length could vary within a roll such that the length would be a minimum for the bags at the center of the roll and then increase for the bags positioned radially outward on the roll. This arrangment could be employed for rolls having a large number of bags to insure that :
after each bag is dispensed from the roll, the leading end of the succeeding bag would project through the opening in the roll by a relatively fixed amount.
It should be noted that plastic bags are generally . .
quite slippery and, therefore, even if the bags are tightly rolled, each bag when being removed can easily slide upon the overlapped or interleaved area of the succeeding bag while also carrying with it the leading edge of said succeeding bag.
The sequential arr~ngement of the overlapped bags can be rolled from either end such that the inner-most wound bag partially overlaps the succeeding bag or the innermost wound bag is partially overlapped by the succeeding bag. Preferably, the innermost wound bag `~
should be o~erlapped by the succeeding wound bag so as -to facilitate the carrying of the leading edge of the succedding bag through the opening.
The container for the bag roll assembly can be ' a cylindrically shaped container or a rectangularly shaped container, preferably both of which should have an internal volume substantially equal to the volume of ;

In Figure 1, there is shown a pIurality o `~
physically discrete flattened bags 2 each having a closed end 4, an open end 6 and laterally closed sides 8. It is .
to be understood that the closed sides of the bags could be formed with inturned gu~sets or tucked portions ~o that upon being opened from the flattened ~tate, the 12.
, :~
" . . . .. . .
~47~
overall cross-sectional are~ of the bags can be sub-stantlally rectangular. The bags whlch can be used in connection with this invention are preferably made of relatively thln plastlc film material. The bags 2 are shown in an overlapping sequence in a manner ~uch that their lateral sides 8 are in alignmen~ The overlapped length identi~ied by X ic somewhat variable but should be as speclfled above. A sequence of overlapped bags 2 i8 shown in Figure 2 loosely rolled up with a space or opening 10 at the axis of the roll 12. As is apparent from Figure 2~ the physically discrete bags are serially ~-~
related and can be sequentially dispensed from the roll 12 one at a time starting from the innermost wound bag and proceeding to the next lnnermost wound bag with each bag~carrying with it the leading edge of the next sequenced bag in the roll. Thus, when the innermost bag 2 i8 grasped and slid out from the opening 10 in . ~ .
roll 12, the open end 6 will be the leading edge thereby facilitating the opening of the bag.
In Figure 3 there i5 shown a plurality of physically discrete flattened bags 3 each having an open end 5, a clo~ed end 7 and laterally closed sides 9 D
As discussed above, the closed sides of ~he bags 3 could be formed with inturned gussets or tucked portions so that upon being opened from the flattened state, the overall cross-sectional area of the bag~ can be substan-tially rectangular. The bag~ 3, shown in Figure 3 in 13. -Z ' ~ ', an end-to-end alignment, are shown in Figure 4 loo~ely '`-rolled up with a spAce or opening 11 at the axis of the ~:
roll 13. As is apparent from Figure 4, the physically '~,, discrete bags are serially related and can be sequentially ';~
dispensed from the roll one at a time starting from ~ ' the innermost wound bag and proceeding to the next inner- ,, most wound bag. As opposed to the bag roll assembly 12 shown in Figure 2, the bag roll as~embly 13 shown in Figure 4 is such that the removal of the innermost wound bag will not carry with it the leading edge of the next innermost wound bag. This is due to the fact that the sequential bags are not initially overlapped or ,~ ,~
, interleaved prior to rolling. Thus the innermost wound bag can slide out from the center of the roll without carrying with it the next bag since, during assembly, the innermost bag is completely rolled prior to rolling the " ~ :
next~bag on top of it and then each succe~sive bag is rolled on top of a previously fully rolled bag.
In ~igure 5 there i~ shown a plurality of '~
physically discrete flattened bag~ 15 each havlng an open ''~
end 25, a closed end 23 and laterally closed sides 17~
Each bag 15 is shown folded lengthwise along lines 19 &nd 35 and widthwise along line 21. The transversely folded :
bags 15 form a "V" s,haped configuration with the lesding edge defined by fold line 21 and the two trail~ng edges~
shown spaced apart or illustrative purposes, defined by lines 29 and 31. As shown in Figure 5, the leading edge 21 of each bag is inserted a distance or length X' between 14- ' . .
~C~47~2 edges 29 and 31 ~f a preceding bag, said lnterleaved length being variable as specified above. A sequence of interleaved bags 15' having an open end 25', closed end 23', a leading folded edge 21'and trailing edges 29'and 31'is shown inFigure ,~
6 loosely rolled up wlth a space or opening 27 at the~
axis of the roll 33. As is apparent from Figure 6, the ~: :
physically discrete bags are serially related and can be sequentially dispensed from the roll 33 one at a time starting fr~m the innermost wound bag and proceeding :~
to ~he next innermost wound bag with each bag carrying . ~
with it the leading folded edge of the next sequenced.~ :
bag in the roll. Thus when the innermost bag 15' is `~ ~
grasped and slid out from the opening 27 in the roll 33, ~ ~:
the next innermost wound bag will pro~ect~from ~he roll where it will be availab~ for gripping by the user, If the width of the bags to be used in accordance with this invention is too wide, then, as shown in Figure 7, the individual bags 20 can first be folded two 3 :
or more times lengthwise thereb~ reducing the width to ~;
a manageable size that can be conveniently handled during as~embly and which will provide an overall si~e paokage convenient for ~toring on household cabinet shelves.
As~shown in Figure 7, bag~ 20 have been folded aIong :
lines 28, 30 and 32 thereby reducing the width o~ the ~ :
bags to 1/4 the original width. The closed sides 22 of each bag are shown superimpofied with the open ends 24 being opposite to the closed ends 2~. Although the fold .
: ,, :~0470~
lines 28, 30 and 32 are shown parallel to the closed sides 22, it iiq wlthin the scope of this invent~on that the fold lines extend parallel to the open and closed end~ of the bag if desired. However, the folded bag arrangement shown is preferred because it leaves the open ends of the bags exposed so that the open end of each bag will be the leading edge of the bag as it is dispensed from the roll. Thus the user will not have to : -~
unfold the bag looking for the open end If desired, the bags could be tranqversely folded in addition to ~:
being longitudinally folded. . :
Figure 8 shows an exploded view of one embodiment ~.
of the subject invention employing a coreless roll of ~ .:
overlapped bags, Specifically, a rolled bag assembly 40, shown loosely rolled for purposes of illustration only, is provided with a rigid bottom disc support 42 made of a material such as chipboard, cardboar , plastic sheet .
and laminations thereof, or the like, a top disc cover 44 made of a material similar to or identical to support 42 ~ :
and a flexible wrapper material 46, preferably opaque, for partlally enveloping the outer peripheral surface of roll assembly 40. The wrapper material 46 could also envelop the entire outer periphery of roll assembly 40 and could be made of paper, plastic film, or the like, and contain a label 48 with printable information 50 ~ ;
for identifying the size of the bags and the manufacturer.
With a tightly rolled assembly 40, support 42, cover 44 -16, , ,' :
... , . , ,,; " , ~ -- 1047~2 ~ `
and wrapper 46 assembled together, an overwrap 52 such as a heat-shrinkable transparent fllm, an elastic film ~leeve, a cellophane film, or the like, could envelop the outer peripheral surface of the roll assembly and at least a portion of the top and bottom discs to provide ~ `
a compact overall cylindrical package of discrete over-lapped or interleaved rolled bags. Top cover 44 is shown with an opening 54 which will be proximal the axis of roll assembly 40 when it is assembled to form a c~m-plete package. The opening 54 in top cover 44 could be made by having one or more straight or curved perfora~
tions or slit lines through the cover which could be punched out through the application of a 8mall amount of pressure. Once the portion of the cover contained within the slits is removed from the surface of the cover, ;~
an opening 54 will be made through which the bags can be removed from the center of the roll assembly one at a time. It i9 to be understood that the opening could be circular, semi-circular, rectangular, triangular, cruciform or trefoil shaped, U-shaped or any other con-figuration that will be suitable to accommodate the removal of the bags.
As shown in Figures 8 and 99 perforation3 could i~
outline an arcuate area such that when a central portion 57 is removed, the arcuate area is formable into a carrying handle 56.

are shown ully assembled in Flgure 9 after one or more bags have been removed. The removal of a bag from the package will carry with lt the leading edge of the succeeding innermost wound bag 2 through opening 54 thereby projecting said bag through said opening 54 a ~hown in Figure 9. Thus the user will always have the leading edge of a succeeding bag available for gripping ~ ~ -so t}at, when desired, a bag can be easily slid from the package whereupon it will ~e ready for use. The extent to which the leading edge of the bag is to be ~;~
projected from the opening can be adjustPd by varying the overlapped length of adjacent bags and/or by varying ~ -the degree of tightness in the roll assemblyO

A flattened cylindrical or oval roll assembly 60 `
is shown in Figure 10 with the trailing edge of the outermost wound bag secured by a suitable piece of tape 62. Disposed in theopening64 are à number of conven~
tional closure means 66 such as twist-ties~ keylocks, or the like, corresponding to or greater than the number of discrete bags 2 in the roll assembly 60. Each closure means 66 is used to secure the gathered opened edge of a full bag in a closed stateO
In Figure 11 an oval bag roll assembly is~`-~hown enclosed in a rectangular container 70 having an oval opening 72. The opéning 72 could be produced using ~
the perforation or slit technique discussed in conjunction ;~-with Figure 8 to yield a generally oval opening in one 18.

of the end walls of the container. As shown in Figure 11, after one or more bags are removed~ the leading edge of the next sequentially rolled bag 2 will project through opening 72 thereby being avallable for the user to grip when an additional bag is desired. This type of package embodiment is ideally suitable for storing on a shelf.
The bag dispenser of this invention has been used to successfully package polyethylene flexible 0.0015 inch (0.038 mm) thick film bags measuring 30 inches (76~2 cm) wide by 37 inches (93.98 cm) longO The bags were initially folded with two longitudinal parallel folds to a size of 7.5 inches (19.1 cm~ wide by 37 inches (93.98 cm) long. Forty longitudinal folded bags were then arranged as shown in Figure 7 with an overlapped length "X" (Fig.5) of approximately 4 inches (10.2 cm). The folded bags were then rolled into a cylindrical form ~ ` ~
measuring 2.25 inches (5.72 cm) ID and 5.38 inches (13.7 cm) OD. The roll bag assembly was then packaged substantially as shown in Figure 8 using a plastic sheet top cover (polyethylene) having an arcuate shaped slit arrangement, a plastic sheet bottom support disc (poly-ethylene) and a stiff paper wrapper all secured together with pressure-sensitive tape. The opening in the top cover was made by exerting a slight pressure on the area within the sl~t arrangement and then pivoting the arcuate shaped segment upward from the cover, said segment forming 19. ~ -, 47~ ~ Z
handle for the package. Thereafter the removal of the innermo~t wound,bsg through the opening in the cover carried with it the leadlng edge of the succeeding bag ln a manner as shown in Figure 9. Several succeeding bags were then removed one at a time and sfter each bsg was removed, the leading edge of the following bag was pro-~ected through the opening.
A different embodiment of the bag dispenser of ;~ ~;
this invention wss again used to successfully psckage polyethylene ~lexible .0015 inch (0.038 mm) thick film .
bags measuring 30 inches (76.2'cm) wide by 37 inches (93.98 cm) long. The bsgs were initially folded with ,~
two longitudinal parallel folds to a size of 7,5 inche (19.1 cm) wide by 37 inches (93.98 cm) long. Twelve longi~
tudinal folded bags were then arranged as shown in ,~
Figure 7 with an overlapped length of approximately 4 inches (10.2 cm3. The folded bags were then rolled ,~
into a cylindrical form measuring 2025 inches (5.72 cm~ ID
and 3.75,inches (9.5~cm) ODo The cylindrical b~ag assembly was then flattened to an oval,form as shown in Flgure 10~ , , and after inserting ten closure means into the center ~ ' , of the roll, it was placed in a rectangular container as shown in FLgurell, said container measuring 8.75 inches ~, (22.2 cm) long, 4 inches (10.2 cm) wide and 2~5 inches' ~6.4 cm) high. Slits were placed in one of the end aces of the container defining an o~al areaO A slight pressure .. ... . .

on the oval area as defined by the slits provided an openlng in the end of the container proximal the axis -~
of th~ roll assembly through which the bags were then removed one at a time. As discussed in Example l, the removal of a bag from the roll assembly carried with it the leading edge of the succeeding bag in the sequence thereby pro~ecting said leading edge through the opening in the end face of the container as shown in Figure 11.
E~AMPLE 3 A rectangular bag assembly similar to that in Example 2 was produced except that the individual bags -were not overlapped prior to being rolled but interleaved .
as shown in Figure 5 and banded in stiff paper and glued. i The banded bag assembly was then packed in a rectangular carton as described in Example 2 and when the bags were removed one at a time, each bag earried with it the leading edge of the next bag in the sequence.
It should be understood that the foregoing dls~
closure relates to preerred embodiments of the invention and it ls intended to cover all changes and modifications ;-of the invention which do not depart from the spirit and scope of the appended claims.
