Zipper and zipper arrangements and methods of manufacturing the same

A zipper arrangement for use in manufacturing thermoplastic bags, said zipper arrangement comprising:

• a zipper including first and second opposing tracks, said first track having a first profile and said second track having a second profile, said first and second profiles being releasably engageable to each other, said first track having one or more spaced primary notches interrupting said first profile;
• and
• at least one slider inserted onto said first profile via one of said primary notches, said slider being adapted to engage and disengage said first and second profiles in response to movement along said zipper, wherein a depth of said primary notches is less than an internal opening of said slider.

A zipper arrangement for use in manufacturing thermoplastic bags, said zipper arrangement comprising:

• a zipper including first and second opposing tracks, said first track having a first profile and said second track having a second profile, said first and second profiles being releasable engageable to each other, said first track having one or more spaced primary notches interrupting said first profile;
• at least one slider inserted onto said first profile via one of said primary notches, said slider being adapted to engage and disengage said first and second profiles in response to movement along said zipper, wherein said slider is pushed downward onto said second profile.

A zipper arrangement for use in manufacturing thermoplastic bags, said zipper arrangement comprising:

• a zipper including first and second opposing tracks, said first track having a first profile and one or more spaced first primary notches interrupting said first profile, said second track having a second profile and one or more spaced second primary notches interrupting said second profile, said second primary notches being generally aligned with respective ones of said first primary notches to form one or more aligned pairs of primary notches, said first and second profiles being releasably engageable to each other;
• wherein said first track has a first fin extending downward from said first profile, wherein said second track has a second fin extending downward from said second profile, wherein said first fin is detachably connected to said second fin, and
• at least one slider inserted onto said zipper via one of said aligned pairs of primary notches, said slider being adapted to engage and disengage said first and second profiles in response to movement along said zipper.

A zipper arrangement for use in manufacturing thermoplastic bags, said zipper arrangement comprising:

• a zipper including first and second opposing tracks, said first track having a first profile and one or more spaced first primary notches interrupting said first profile, said second track having a second profile and one or more spaced second primary notches interrupting said second profile, said second primary notches being generally aligned with respective ones of said first primary notches to form one or more aligned pairs of primary notches, said first and second profiles being releasably engageable to each other;
• and
• at least one slider inserted onto said zipper via one of said aligned pairs of primary notches, said slider being adapted to engage and disengage said first and second profiles in response to movement along said zipper, wherein a depth of said first primary notches is less than an internal opening of said sliders.

A zipper arrangement for use in manufacturing thermoplastic bags, said zipper arrangement comprising:

• a zipper including first and second opposing tracks, said first track having a first profile and one or more spaced first primary notches interrupting said first profile, said second track having a second profile and one or more spaced second primary notches interrupting said second profile, said second primary notches being generally aligned with respective ones of said first primary notches to form one or more aligned pairs of primary notches, said first and second profiles being releasably engageable to each other;
• wherein said first track includes one or more first secondary notches and said second track includes one or more second secondary notches, said second secondary notches being generally aligned with respective ones of said first secondary notches to form aligned pairs of secondary notches, said first and second secondary notches extending at least partially into said respective first and second profiles, and
• at least one slider inserted onto said zipper via one of said aligned pairs of primary notches, said slider being adapted to engage and disengage said first and second profiles in response to movement along said zipped.

A folded zipper for use in manufacturing thermoplastic bags, said zipper comprising:

• first and second opposing tracks, said first track having a first profile and one or more spaced first primary notches interrupting said first profile, said second track having a second profile and one or more spaced second primary notches interrupting said second profile, said second primary notches being generally aligned with respective ones of said first primary notches to form aligned pairs of primary notches said first and second profiles being releasably engageable to each other;
• said zipper including a plurality of fold areas generally transverse to a length of said zipper and aligned with respective ones of said aligned pairs of notches, said zipper being folded along said fold areas.

A method of making a folded zipper for use in manufacturing thermoplastic bags, said method comprising:

• providing a zipper comprising a zipper, said zipper including first and second opposing tracks, said first track having a first profile and one or more spaced first primary notches interrupting said first profile, said second track having a second profile and one or more spaced second primary notches interrupting said second profile, said second primary notches being generally aligned with respective ones of said first primary notches to form aligned pairs of primary notches, said first and second profiles being releasably engageable to each other, said zipper including a plurality of fold areas generally transverse to a length of said zipper and aligned with respective ones of said aligned pairs of notches;
• and
• folding said zipper along said fold areas.
