Abstract: The present invention includes a reclosable bag having first and second walls and an open top defined by first and second elongate flexible fastener strips attached to the first and second walls, respectively, adjacent the top of the walls. One of the fastener strips has a profile portion forming at least one groove and the other fastener strip has a profile portion forming at least one rib with a portion of each rib received and retained in one of said grooves when the bag top is closed. Each of the fastener strips has a base connected to the respective wall, and each of the strips has an upper edge adjacent the upper edge of the other strip. Third and fourth fastener strips are located within the bag walls parallel to and below the first and second fastener strips. The third and fourth fattener strips have one or more pairs of ribs and grooves.

Abstract: A reclosable bag with front and rear walls defining a top opening between them is closable with a fold-over hood on one of the walls. The walls are made of a flexible material that may be folded downward from the top opening in a series of one or more folds. The hood extends along an upper portion of the wall near, but spaced apart from, the top opening. The fold-over hood is effective for folding over and retaining the upper portions of the front and rear walls after they have been folded downward from the top opening in a series of one or more folds until they reach the hood.

Abstract: A reclosable bag is disclosed wherein a fastener strip has male and female cooperating profiles mounted thereon. The fastener strip is mounted on the inside surface of the rear panel of the bag with one of the profiles in the bag. The fastener strip is foldable over the front panel of the bag to a position wherein the male and female profiles cooperate to close the bag with the front panel between the profiles.

Abstract: An apparatus for the continuous packaging of flexible bags is adapted for use with a continuous bag manufacturing machine. Separate bags are received on a conveyor which conveys the bags to a stacking station at the end of the conveyor. At the stacking station, the bags are stacked in a catch tray until a predetermined number of bags have been collected, at which point the tray is opened to drop the bags into an open container supported on a turntable beneath the catch tray. The turntable is rotatable to convey the open container away from the stacking station to an unloading station when the container has been filled with bags. The turntable rotatably supports a number of support plates evenly distributed around the perimeter of the turntable, upon which an open container sits. A multi-motion actuator situated at the stacking station underneath the turntable is operable to rotate the support plate at the stacking station relative to the turntable.

Abstract: A shipping sack having side walls defining a mouth from which contents may be discharged, includes a non-reclosable stitched fastener across and closing the mouth. The stitched fastener includes a removable chain stitch and a removable rip tape for facilitating manual opening of the stitched fastener. The rip tape in one embodiment is composed of a strip having a cut-out opening therethrough defining a handle adapted to be manually grasped for carrying the shipping sack. The rip tape also includes a free end extending beyond the edge of the shipping sack to facilitate manual access to the rip tape and to facilitate pulling the rip tape to remove the stitched fastener. In another embodiment, the handle rip tape includes a continuous row of finger holes in lieu of the single cut-out opening.

Abstract: A bag structure includes a tubular bag body closed at one end and at its edges but open at the bag top. A top closure is affixed to the bag body covering the bag top. The bag body includes opposite wall panels which include a opposite outer layers and opposite inner layers, in which the outer layers are formed from a material that is more readily fusible than the material of the inner layers. The top closure includes opposite attachment flanges composed of a material that is more readily fusible to the outer layer than the inner layer. In one specific embodiment, a heated pressure bar is applied to heat seal the attachment flanges of the top closure to the outer layers of the bag body, while the inner layers of the wall panels remain intact and are not fused together. The inner layer material has a fusion temperature higher than the temperature at which the outer layers and top closure attachment flanges fuse.

Abstract: A tamper evident bag having a non-reusable frangible fastener profile assembly comprising two sets of lockable fastener profile elements specially constructed to manually lock together without the use of tools, and which once locked cannot be forcibly pulled apart. The bag includes a frangible connector bridge which will break away when the bag is opened indicating that the bag has been tampered with. The construction of the fastener elements also assures proper alignment of the lockable fastener profile elements across the length of the upper portion of the bag wall panels, making interlocking closure easy when pressure is applied on the outer walls of the bag behind the fastener profile elements.

Abstract: A tamper evident recloseable bag is disclosed having two opposing wall panels, a recloseable fastener profile assembly extending across the upper portion of the wall panels and a hooded closure enveloping the entire upper portion of the wall panels. The hooded closure arrangement seals the bags closed until intentional opening of the bag is desired, at which time the hooded closure can be removed by lightly pulling it in an upwardly direction. The removed hooded closure visually indicates the opened condition of the bag.

The stitched fastener includes a removable chain stitch and a removable rip tape for facilitating manual opening of the stitched fastener. The rip tape is composed of a strip having a cut-out opening therethrough defining a handle adapted to be manually grasped for carry the shipping sack. The rip tape also includes a free end extending beyond the edge of the shipping sack to facilitate manual access to the rip tape and to facilitate pulling the rip tape to remove the stitched fastener.

Abstract: A recloseable bag having a fastener assembly comprising two fastener profiles, each having a hinged double wall construction to prevent unintended opening of the bag due to internal forces exerted on the inside of the bag wall panels. The bag is easily openable when suh is intended by simple manipulation of pull flanges, thereby providing access to the interior of the bag. The hinged double wall construction also assures proper alignment of the fastener profiles across the length of the upper portion of the bag wall panels, making interlocking closure easy when pressure is applied on the outer walls of the bag behind the fastener profiles.
