FIELD OF THE INVENTION
The present invention is directed to zippers. zipper arrangements, and methods of manufacturing the same. Specifically, the present invention is directed towards zipper arrangements having a notched zipper and at least one slider for use in manufacturing thermoplastic bags and methods of manufacturing the same.
BACKGROUND OF THE INVENTION
Plastic bags are popular for storing food and other items. Zippered plastic bags that can be securely closed and reopened are particularly popular due to their perceived ability to maintain freshness of the food stored in the bags and/or to ~o minimize or eliminate leakage into and out of the bag. These bags are used one at a time by consumers. These bags are also used by businesses to package items that are then sold to consumers. For example, nuts, candy, snacks, ingredients, salt, cheese, and other food and non-food products are packed in these bags by form, fill and seal machines.
~s Slider bags have become popular with customers for a variety of reasons, including difficulty in opening and closing a zippered bag without a slider.
Product manufacturers have not, however, used zippers with sliders in their form, fill and seal machines for a variety of reasons. Some of these reasons include the difficulty in having a reliable assembly of sliders to zipper at form, fill and seal manufacturing zo rates, supplying zipper with sliders that are not prone to machine jamming and excessive downtime. and installing sliders in tight and constraining areas in form, fill and seal machine footprints.

The slider is inserted onto the first profile via a respective one of the primary notches. The slider is adapted to engage and disengage the first and second profiles in response to movement along the zipper.
According to another embodiment of the present invention, the second track has a second profile and one or more spaced primary notches interrupting the second profile. The second primary notches are generally aligned with respective ones of the first primary notches to form aligned pairs of primary notches. The slider is inserted ~o onto the first profile via a respective one of the aligned pairs of primary notches.
According to yet another embodiment of the present invention, a folded zipper includes f rst and second opposing tracks that each have one or more primary notches interrupting respective profiles. The primary notches are generally aligned to respective ones of the first primary notches to form aligned pairs of primary notches.
zs The zipper includes a plurality of fold areas generally transverse to a length of the zipper and the zipper is folded along the fold areas.
According to a further embodiment. a folded zipper has a first track having one or more primary notches and a second track having one or more spaced slits interrupting the second profile. The slits are generally aligned to respective ones of ~o the primary notches. The zipper includes a plurality of fold areas generally transverse to a length of the zipper and the zipper is folded along the fold areas.
According to one method of the present invention, a zipper and at least one slider are provided. The first track has one or more spaced primary notches interrupting the first profile. The slider is mounted onto a second profile and into a respective one of the primary notches. The slider is slid onto the first profile via a respective one the primary notches.

DESCRIPTION OF ILLL'STR.aTIVE EI~TBODIMEN'CS
Turning now to the drawings, FIG. 1 illustrates a zipper or fastener 10 having a plurality of generally aligned pairs of primary notches 12 according to one embodiment of the present invention. 'the primary notches 12 are shown as being spaced at a distance W that generally corresponds to a width of a thermoplastic bag.
The primary notches 12 each have a distance D 1 extending from a top surface of the zipper 10. FIG. 2 illustrates a mouth portion of a reclaseable package or bag s having a slider 16 on the zipper 10, while FIG. 3 illustrates the zipper 10 of the mouth portion of the recloseable package 14 taken along line 3-3 of FIG. 2.
Referring to FIGS. 2 and 3, the mouth portion of the recloseable package I4 includes a pair of opposing wall panels 18 and 20 made of polymeric film, mufti-layer and muhi-component laminates, or co-extrusions. The pair of opposing wall panels io 18 and 20 make up a package body 22 and define a receptacle space 24.
Connected to the wall panel 18 is a male track 26 having a male profile 28 and a first fin portion 30 extending downward from the male profile 28_ Connected to the other wall panel is a female track 32 having a female profile 34 and a second fin portion 36 extending downward from the fernaIe profile 34.
is The male and female profiles 28, 34 are releasabIy engageable with each other to provide a recloseable seal to the package. In the illustrated embodiment of FIG. 3, the lower edges of the first and second fin portions 30, 36 are joined to each other along a one time breakable preferential area of weakness or preferential tear area 38 to form a one time openable tamper evident feature 40. The fins may also be formed io from one piece that has an area of weakness or preferential tear area. The joined first and second fin portions 30, 36 have a generally U-shaped or V-shaped cross-sectional configuration. The tamper evident feature 40 is described in detail in U.S.
Patent No. 5,964,532.
It is not necessary that the first and second fin 30, 36 be releasably engaged to as each other by a one time breakable preferential area of weakness. For example, the first fin 30 may be separate from the second fin 36 according to another embodiment of the present invention.
The recloseable package 14 has the slider 16 (FIG. 2) slidably mounted to the zipper 10 for movement bet<veen a closed and open position. The male and female 3o profiles 28. 34 are engaged to each other, while the slider 16 is in the closed position, and movement of the slider 16 from the closed position to the open position WO 0016?603 PC'TIUS00l12t83 ~i disengages the male and female profiles 28. :34 from each other. The manner of operation of this zipper and slider arrangement is described in detail in U.S.
Patent No. 5,063.644 to Herrington, .lr. et. al.
The sliders to be used in the present invention may include various sliders that > are adapted to move and disengage the male and female profiles 28, 34 from each other. One such slider {slider 16) is depicted in FIG. 2. 'The slider I 6 of FIG. 2 is generally U-shaped and includes a transverse support member 42 with two depending legs 44, 46 therefrom. A separator finger 48 depends from the transverse support member 42 and is disposed between the depending legs 44, 46. The separator finger ~0 48 extends at Ieast partially between the male and female profiles 28, 34 to aid in disengaging the male and female profiles 28, 34 as the slider 16 is moved along the zipper 10.
FIG. 4 illustrates a zipper arrangement 50 comprising a zipper 52 and a plurality of the sliders 16. A slider 16a is located in a spaced primary notch 12, while a the slider 16b is shown in a position straddling the male and female profiles.
Referring to FIGS. I, 3 and 4, the male track 26 has a plurality of spaced first primary notches 12a interrupting the male profile 28, while the female track 32 has a plurality of second primary notches 12b interrupting the female profile 34. The first primary notches 12a are generally aligned with the second primary notches 12b to form the aligned pairs of primary notches i 2. The sliders 16 are adapted to slide onto the male and female profiles 28, 34 via the respective aligned pairs of primary notches 12. At least one of the first and second primary notches 12a, 12b may interrupt a portion of the first fin 30 and/or the second fin 36, respectively.
According to another embodiment of the present invention, the zipper may have one slider instead of the plurality of sliders described in the zipper arrangement of FIG. 4. According to another embodiment of the present invention. the zipper rnay have one first primary notch and/or one second primary notch. Likewise, the zipper may have one secondary notch.
The plurality of primary notches 12 are preferably located near the ends of the ~o recloseable package 14 for a vanetv of reasons. I=or example. locatine the primary notches 12 near the ends of the package 14 is generally more aesthetically pleasing to customers. In addition. this location allows the slider 16 to move and open the WO 00/67603 pCT/US00/12183 package 14 across a greater distance. resulting in a wider mouth of the package 14.
Locating the primary notches 12 near the ends of the package 14 may also assist in forming the side seals of the package 14 since the profiles do not need to be flattened.
Side seals of the package 14 may be formed more easily and/or efficiently because of _ the reduction or elimination in temperatures, pressures, and times associated with fusing the male and female profiles 28. 34 together near the ends of the package 14.
Locating the primary notches near the ends of the package 14 may eliminate the need to fuse the male and females profiles 28, 34 together if the male and femaie profiles 28, 34 are cut away at the areas where the side sealing occurs.
io The relationship between the notch 12 and the slider 16 will be discussed with respect to FIG. 4. A distance D 1 of the notch preferably is less than a distance D3 (the internal opening of the slider 16) so that the slider may be placed more easily onto the profiles. As shown in FIG. 4, the sliders 16a, 16b overlap a portion of the fins to assist in aligning the position of the sliders 16a, 16b prior to threading onto the Is profiles. Specifcally, the opening of the sliders 16a, I6b between the slider wings falls between the fins. The aligned primary notch 12 preferably has a width that is greater than a length L of the slider 16. The aligned primary nLtcln~ . ~.? ~f : iGS. 1 and 4 are shown as extending through the respective male and te~.: r~-~...,.:: in a direction generally transverse to a length of the zipper I 6. The primary notches 12 do ~o not, however, extend entirely through the first fin 30 and the second f n 36, respectively, in FIG. 4.
According to another embodiment of the present invention, the zipper may include a plurality of secondary notches. Referring specifically to FIG. 4.
the male track 26 of the zipper arrangement 50 is further interrupted by a plurality of optional ~s first secondary notches 54a, while the female track 32 is further interrupted by a plurality of optional second secondary notches 54b according to another embodiment of the invention. The first secondary notches 54a are generally aligned with the second secondary notches 54b to form generally aligned pairs of secondary notches 54. The aligned notches 54 have a distance D2 extending from a top surface of the ~o zipper 52.
The secondary notches 54 are not adapted to engage the separator finger 48 of the zipper 16 which inhibits or prevents the slider 16 from disengaging the male and female profiles 28, 34. In other words. the separator 48 is ineffective to force a top portion (the ears) of the male and female pratiles 28, 34 apart so as open the package I=1. The slider rs considered to be "parked" rr-hen it is in this condition.
The secondary notches 54 also give a user of the package 14 the feel of a secure closure and assurance that the bag is closed with certainty. The secondary notches are described in detail in U.S. Patent No. 5,067,208.
The secondary notches 54 are preferably located at the closed end of the bag.
As shown in FIG. 4, the first and second secondary notches 54a, 54b extend at least partially into the respective male and female profiles 28, 34. The aligned secondary notches 54 may be merged into respective aligned primary notches 12 as shown in FIG. 4.
According to another embodiment (FIG. 5) to be used in the present invention, a zipper 60 comprises a male track 62 and a female track 64. The male track includes a male profile 66 and a frst fin 68. The male: track 62 has a plurality of spaced primary notches 70 interrupting the male profile 66. The female track is shown in FIG. ~ as being continuous, and includes a female profile 72 and a second fin 74. A
slider (e.,,., the slider in FIG. 4) is adapted to be placed onto the female profile 72 in an area where the primary notch 70 has been formed. The slider is slid onto the male profile 66 via the primary notch 70. The zipper 60 may include one slider or a plurality of sliders. Likewise, according to yet another embodiment, a slider may be placed onto a continuous male; track (not shown) in an area where the female track has been interrupted by a primary notch. Then, the slider is slid onto the female profile via the primary notch.
According to yet another embodiment of the present invention, a zipper (not shown) comprises a male track and a female track. The male track includes a male =' profile and the female track includes a female profile. Neither the male track nor the female track comprises a first :fin or a second fin, respectively, according to this embodiment. The zipper includes a pluraliru of ~;enerallv aligned primary notches formed in the zipper. According to one embodiment of the present invention, a slider may be placed in a respective one of the plurality of aligned primary notches.
A slider is then slid onto the male and female profiles via a respective one of the aligned primary notches. Alternatively, a pluraliru of sliders are slid onto the male and female profiles via respective ones of the aligned primary notches. Alternatively, a primary notch may interrupt only one of the profiles, as described above with respect to FIG.
A filled and sealed food or storage bag may be formed by a form. fill and seal machine. The zipper arrangement of FIG. 6 includes a zipper 10 and a plurality of > sliders 16. Bag film or web 82, zippers 10, and sliders 16 are components for assembling into a complete bag. A schematic illustration of a foam, fill and seal machine 80 is provided in FIG_ 6. As depicted at the left side of FIG. 6, the plastic film or web 82 and a zipper 10 with sliders 16 thereon are fed into the form, fill and seal machine 80. The web 82 has already been formed into a generally U-shape to ~o define a first side wall 84, a second side wall 86, and an open top 88 that will become finished individual bags 90. In FIG. 6, the sliders 16 are shown as mounted on the zipper 10, but the sliders 16 may be first assembled and accumulated, and then mounted on the zipper 10 by the form, fill and seal machine 80.
The zipper I U with the sliders 16 of FIG. 6 is attached to the first side wall 84 ~s of the web 82 by a heated seal bar 92. Side seals 94 are then formed in the web 82 by a second heated seal bar 96, leaving the open tap 88 as the only access to the interior of the formed bag 90. Another second heated seal bar (hidden in FIG. 6) is typically located on the opposite side of the second heated seal bar 96 and works in conjunction with the seal bar 9b in forming the side seals 94. The bag 90 is then moved under a zo fill spout 98 through which a product 100 is deposited into the interior of each bag 90.
As discussed above, product 100 may be nuts, candy, snacks, ingredients, salt, cheese, and other food and non-food products. After the bag 90 is filled, the second side wall 86 of the bag 90 is sealed to the zipper 10 by a third heated seal bar 102.
The individual bags 90 are then separated from each other by a knife 104 that cuts the web a 82 at the side seals 94. The filled bags 90 can then be shipped to retailers for sale to consumers.
The bag 90 may have an cnd termination or stop (not shown) for inhibiting or preventing the slider 16 from going past the ends of the zipper. 'The end terminations also hold the male and female profiles together to resist stresses applied to the profiles ~o during normal use of the plastic bag. One type of end termination is ui the form of a str°ap/clip that wraps over the top of a zipper. Further information concerning such an end termination may be found in U.S. Patent No. 5.067,208.

The punching apparatus 160 includes a movable member 162 and an air cylinder mechanism 163. The air cylinder mechanism 163 controls the ~o movement of the moveable member 162.
The moveable member 162 is shown in FIG. 8 as punching aligned primary notches that extend through the male and female profiles. The moveable member preferably leaves at least a portion of the first and second fins so as to allow a slider to be placed onto a cut edge of the fins. A portion i64 from the zipper 10 is shown as ~s being discharged from the zipper 10 by the moveable member 162. The moveable member 162 notches the zipper 10 at desired inten~als, such as intervals being about a bag distance apart.
The punching apparatus 160 may also contain a second moveable member (not shown) that can form a plurality of secondary notches in a similar manner as described ;o above for the moveable member 162. Alternatively, the punching apparatus may comprise a tiered moveable member (not shown) that simultaneously punches a plurality of aligned primary and secondary notches. According to another embodiment, a punching apparatus (not shown) may be designed to punch a first track WO 00!67603 PCT1US00/12183 without punching a second track. One such punching apparatus would include a moveable member located vertically above the zipper and adapted to move in a downward direction for punching a first track without punching a second track:. This embodiment may be employed without first separating the male and female profiles.
s lZethod Of Placing At Least Une Slider Onto A Zipper One method of placing at least one slider onto a zipper is shown in FIGS. 9-11. Referring to FIG. 9. an escapement mechanism 180 drops the sliders 16 one at a time in respective ones of the aligned pairs of the primary notches of the zipper 10.
The escapement mechanism 1 SU is located downstream from the punching apparatus io 160 of FIG. 8. The escapement mechanism 180 is preferably ane hag repeat downsaeam from the punching apparatus 160. The escapement mechanism 180 may be located upstream from the form, fill and seal machine discussed above in FIG. 6.
The escapement mechanism 180 comprises a slider holder I82, a threader or slider finger 184, and a restraining finger 186. The slider holder 182 is designed to be i s compatible with an assembly of sliders 16 or individual sliders. The slider holder 182 includes a vertical column with a channel sized to hold the sliders 16. The channel of the slider holder 182 includes an open top and an open bottom. It is contemplated that the slider holder 182 may be shaped in a different manner than shown in FIG.
9. For example, the slider holder may be rectangular or square. Additional examples are o shown in U.S. Patents 6,289,61 and 6,292,986. The shape ofthe slider holder generally corresponds to the shape of the assembly of the sliders or individual sliders. The slider holder 182 is preferably designed to allow one slider 16 at a time to be placed in a primary notch of the zipper 10.
As shown in FIG. 9, a zipper 10 is advanced toward the escapement '~ mechanism l 80 in a direction of the arrow. The zipper 10 may be pushed or pulled through the escapement mechanism 180. At a time when one of the aligned pairs of primary notches is generally located below the open bottom of the channel of the slider holder 182, a slider 1 f:>c is dropped in the aligned pair of primary notches (hidden in FIG. 9) of the zipper 10. The slider 16c may be placed in the notches by o gravity and driven mechanically or electro-mechanically. The zipper 10 continues to move forward through the escapement mechanism 180. 'The threader finger 184 engages the dropped slider I 6c and holds it in place as the zipper 10 is either pushed or pulled such that the slider 16c is threaded onto the profiles. An edge of the slider 16c abuts the threader finger 184 and is prevented from moving forward with the zipper 10. Thus, the aligned pair of primary notches is moving away from the slider _ 16c, while the slider 16c is being moved along the mate and female profiles.
Referring to FIG. 10, the threader finger 184 is then moved away from the path of the slider 16c, resulting in the slider 16c moving forward with the zipper 10. The movement of the threader finger 184 from the path of the slider 16c corresponds to the desired placement of the slider 16c relative to a primary notch 12c. If a greater io distance is desired between the slider 16c and the notch 12c, then the threader finger 184 remains abutting the slider 16c for a longer period of time. At the same time that the threader finger 184 is moved from the path of the slider 16c, the restraining fnger 186 is moved toward the sliders 16. The restraining finger 186 holds the next slider ( 16d) in place as the zipper 10 is being advanced through the escapement mechanism >> I80.
According to this embodiment, the threader finger I 84 and the restraining finger 186 are powered by independent pistons. Internal air passages allow only one of the threader finger 184 and the restraining finger 186 to be fully retracted when the other is completely extended. Referring to FIG. 11, the threader finger 184 is returned .o to the same position shown in FIG. 9 after the slider 16c ha.s advanced past the threader finger 184. At the same time, the restraining finger 186 returns to a position away from the assembly of sliders 16. The next slider (16d) will be placed into an aligned pair of primary notches 12d as the zipper 10 is advanced forward.
According to one embodiment, the slider to be used in the method described ~s above may be of the type described above in FIG. 2. A separator finger of the slider may extend at least partially between the male and female profiles so as to disengage the male and female profiles in response to movement along the zipper. It is preferable that the slider be positioned in the primary notch so that the separator finger of the slider remains between the male and female profiles.
3o According to another method of the present invention. a slider may be placed on a zipper as described above. The zipper may be of a length generally corresponding to a width of the bag after the slider is placed on the zipper.

1-1~
According to yet another method of the present invention. a slider may be placed onto a zipper where only a first track has a plurality of spaced primary notches interrupting a first profile. In this method. the sliders are pushed downward onto a second profile and into respective ones of the primary notches. The sliders are slid onto the first profile via the respective primary notches. 'This method may use a similar type of escapement mechanism 180 that would allow the sliders to be pushed downward onto a second profile. The sliders of the type described above in FIG. 2 are preferably positioned so that a separator finger of the slider remains between the male and female profiles. Additional, a slider may be placed on a zipper having a length io generally corresponding to a width of the bag after the slider is placed on the zipper.
While the present invention has been described with reference to the particular embodiments illustrated, those skilled in the art will recognize that many changes and variations may be made thereto without departing from the spirit and scope of the present invention. The embodiments and obvious variations thereof are contemplated i ~ as falling within the scope and spirit of the claimed invention, which is set forth in the following claims.
