Material for making three reclosable bag sections from extruded plastic material

Claim 2

Material for making 3 reclosable bag sections from separable fastener equipped web, comprising: a bag making web having opposite free portions and an intervening portion; said intervening portion being folded upon itself and said free portions being folded inwardly upon themselves, whereby to provide 3 bag sections extending from a juncture in a generally Y orientation and each section having a bag top adjacent to said juncture; and a respective separable profile fastener assembly comprising separably interlockable fastener profiles on each of said bag tops adjacent to said juncture.

Claim 3

Material according to claim 1, wherein said bag sections are separable from one another at said juncture, and pull flanges along the separable fastener assembly of each of the sections.

Claim 4

Material according to claim 1, wherein said web carries thereon, before folding, three spaced sets of fastener profiles, and after the folding each profile of each set is registered in separable fastener assembly with a complementary profile of a different set.

Claim 5

Material according to claim 3, wherein said web comprises extruded plastic tubing wherein said sets of fastener profiles are integrally joined with the tubing, the tubing being separated between the profiles of one of said sets to provide said web and the separated profiles being matched with respective profiles of the other two sets and providing two of said fastener assemblies, and the remaining profiles of said other two sets being registered with one another to provide the third fastener assembly.

Claim 6

Material according to claim 1, wherein said bag sections are of different widths.

Claim 7

Material according to claim 1, wherein said web comprises an extruded plastic tube carrying a multiple of three sets of longitudinally extending complementary parallel fastener profiles, said tube being separated between certain of said profiles, and wherein said certain profiles have therebetween additional sets of profiles, so that the separated tube is foldable into said three Y oriented bag section units having said fastener assemblies.

Claim 8

Material for making a multiple of 3 adjoining reclosable bag sections from extruded plastic tubing, and comprising: an extruded plastic tubular web carrying a multiple of 3 sets of longitudinally extending pairs of adjacently spaced complementary parallel fastener profiles with a respective web panel between the profiles of each set; and sets of fastener profiles being located in such spaced relation to one another that by separating the web panel between the profiles of certain of said sets and folding said web longitudinally into multiples of 3 longitudinal bag sections and interlocking the profiles of said certain sets of profiles with the nearest profiles of other sets of profiles and interlocking the remaining profiles of said other sets with one another, there is provided a respective bag top separable fastener assembly along each of said bag sections.

Claim 9

Material for making a multiple of 3 adjoining reclosable bag sections from extruded plastic tubing, and comprising: an extruded plastic tubular web carrying a multiple of 3 sets of longitudinally extending pairs of adjacently spaced complementary parallel fastener profiles with a respective web panel between the profiles of each set; and sets of fastener profiles being located in such spaced relation to one another that by separating the web panel between the profiles of certain of said sets and folding said web longitudinally into multiples of 3 longitudinal bag sections and interlocking the profiles of said certain sets of profiles with the nearest profiles of other sets of profiles and interlocking the remaining profiles of said other sets with one another, there is provided a respective bag top separable fastener assembly along each of said bag sections.

Claim 10

Material according to claim 7, wherein said tubular web is separated between said certain profiles and the web is folded to provide said bag sections and the folded bag sections are oriented in a generally Y-shaped orientation.

Claim 11

Material according to claim 8, wherein the bag sections are of different widths.

Claim 12

Material according to claim 7, wherein said web panels provide material for pull flanges along said bag top fastener assemblies.

Claim 13

Material according to claim 10, wherein said web panels material provides for pull flanges of different widths for each of said fastener assemblies.

Claim 16

A method according to claim 12, comprising separating said bag sections from one another at juncture of said sections, and forming pull flanges along the separable fastener assembly of each of the sections.

Claim 17

A method according to claim 12, which comprises providing on the web before folding 3 sets of fastener profiles, and in the folding registering each profile of each set in separable fastener assembly with a complementary profile of a different set.

Claim 18

A method according to claim 14, comprising extruding plastic tubing to provide said web and integrally joining said sets of fastener profiles with the tubing, separating the tubing between the profiles of one of said sets and matching the separated profiles with respective profiles of the other 2 sets into a fastener assembly, and registering the remaining profiles of the other 2 sets with one another into a fastener assembly.

Claim 19

A method according to claim 12, which comprises forming said sections of different widths.

Claim 20

A method according to claim 12, which comprises extruding said web in the form of a plastic tube and providing said plastic tube with a multiple of 3 sets of longitudinally extending complementary parallel fastener profiles, separating the tube between certain of the profiles and leaving additional sets of profiles between separated profiles at opposite sides of the separated portions of the web, and folding the separated portions of the web and joining the fasteners of the separated portions into a plurality of Y-oriented bag section units.
