Bag with draw band separably integral with bag body

Claim 2

In a bag made from pliable sheet material providing a bag body with a mouth at one end of the body defined by a lip portion providing a tunnel: said body having an integral portion thereof closed within said tunnel and partially separated therefrom with relatively minute tear points connecting it to the body and providing a flat draw band; and said tunnel having at least one opening therein through which the draw band is adapted to be pulled for closing said mouth; said draw band comprising a folded over double-ply portion of the bag body.

Claim 3

In a bag made from pliable sheet material providing a bag body with a mouth at one end of the body defined by a lip portion providing a tunnel: said body having an integral portion thereof enclosed within said tunnel and partially separated therefrom with relatively minute tear points connecting it to the body and providing a flat draw band; and said tunnel having at least one opening therein through which the draw band is adapted to be pulled for closing said mouth; said tunnel and said draw band comprising integral folded portions of the bag body.

Claim 4

In a bag made from pliable sheet material providing a bag body with a mouth at one end of the body defined by a lip portion providing a tunnel: said body having an integral portion thereof enclosed within said tunnel and partially separated therefrom with relatively minute tear points connecting it to the body and providing a flat draw band; and said tunnel having at least one opening therein through which the draw band is adapted to be pulled for closing said mouth; said tunnel and said draw band comprising integral folded portions of the bag body.

Claim 5

In a bag made from pliable sheet material providing a bag body with a mouth at one end of the body defined by a lip portion providing a tunnel: said body having an integral portion thereof projecting into, extending throughout the length of and enclosed within said tunnel, and said portion being partially separated from the body along a line extending lengthwise throughout the length of the tunnel with relatively minute tear points connecting said portion to the body whereby said portion provides a separable flat draw band; and said tunnel having at least one opening therein through which the draw band is adapted to be pulled for closing said mouth.

Claim 6

In a bag made from pliable sheet material providing a bag body with a mouth at one end of the body defined by a lip portion providing a tunnel: said body having an integral portion thereof projecting into, extending throughout the length of and enclosed within said tunnel, and said portion being partially separated from the body along a line extending lengthwise throughout the length of the tunnel with relatively minute tear points connecting said portion to the body whereby said portion provides a separable flat draw band; and said tunnel having at least one opening therein through which the draw band is adapted to be pulled for closing said mouth.

Claim 7

In a bag according to claim 1, said tunnel comprising a separate tunnel strip applied to said bag body about said mouth to enclose said draw band.

Claim 8

In a bag according to claim 1, the material of the bag and tunnel comprising heat-sealable plastic material, said bag body comprising flat panels joined along opposite side edges, and said opening being at one of said side edges.

Claim 9

In a bag according to claim 1, said opening being defined by a tear-out area of the lip tunnel portion and adapted to be torn out when the draw band is initially pulled out through said opening.

Claim 10

In a bag according to claim 1, said draw band comprising a folded over double-ply portion of the bag body.

Claim 11

In a bag according to claim 1, an additional layer thickness of material along said draw band providing a multi-layer draw band.

Claim 12

In a bag according to claim 1, said tunnel and said draw band comprising integral folded portions of the bag body.

Claim 13

In a bag according to claim 8, a gusset fold of the bag body providing a part of the tunnel at the inside of the mouth providing an initial closure for the mouth.

Claim 14

In a bag made from pliable sheet material and having opposite side edges and a mouth at one end defined by a lip portion thereabout and providing a tunnel: said bag comprising body panels joined together at said side edges; integral portions of said panels projecting into said tunnel and extending throughout the length of the tunnel; two spaced parallel lines of partial separation extending lengthwise of the tunnel in each of said integral panel portions to define a pair of draw bands and with the draw bands of the portions aligned in coextensive relation; the aligned draw bands on said portions being permanently connected together at their ends; and openings in offset relation to one another provided at the opposite ends of the tunnel through which the respective aligned bands are adapted to be pulled in opposite directions for drawing the bag mouth closed by grasping the respective aligned bands at the openings and pulling thereon to separate the bands from one another and from said panels.

Claim 15

In a bag made from pliable sheet material and having opposite side edges and a mouth at one end defined by a lip portion thereabout and providing a tunnel: said bag comprising body panels joined together at said side edges; integral portions of said panels projecting into said tunnel and extending throughout the length of the tunnel; two spaced parallel lines of partial separation extending lengthwise of the tunnel in each of said integral panel portions to define a pair of draw bands and with the draw bands of the portions aligned in coextensive relation; the aligned draw bands on said portions being permanently connected together at their ends; and openings in offset relation to one another provided at the opposite ends of the tunnel through which the respective aligned bands are adapted to be pulled in opposite directions for drawing the bag mouth closed by grasping the respective aligned bands at the openings and pulling thereon to separate the bands from one another and from said panels.

Claim 16

In a bag according to claim 11, said tunnel comprising a separate piece of material folded about said panel portions and secured thereto clear of said draw bands.

Claim 17

In a bag according to claim 12, said panel portions being doubled over within the tunnel to provide double-ply draw bands.

Claim 18

In a bag according to claim 12, reinforcing material extending along said draw bands within said tunnel.

Claim 19

In a bag according to claim 11, said panels being folded upon themselves to provide said tunnel and said integral portions comprising margins of the panels folded into the tunnel.

Claim 20

In a bag according to claim 11, said panels being folded upon themselves to provide said tunnel, additional folds of the panels being enclosed within the tunnel and providing said integral portions, and seams securing the folds inwardly from the bag mouth leaving said portions free within the tunnel for separation of the draw bands along the partial separations in response to the pulling force to draw the bands from said openings.
