Abstract: A series of bags having printable areas thereon with the bags secured at their base to a support strip and the support strip is mounted to a continuous support web such as computer paper by a strip of double surfaced adhesive tape supplied between the strip and computer paper with the computer paper thereafter folded to maintain the bags in registry for subsequent printing.

Abstract: A system for seriatim filling and separating zipper-equipped bags supplied in a chain has a filling station in which each bag mouth is spread open to permit top filling, a closing station in which the zipper profiles of each filled bag are interlocked, and a separation station in which the filled bag is separated from the chain. A pincer action grasps each filled bag, draws the filled bag through the closing and separation stations, and releases the separated and filled bag for collection. The operation of the pincer serves to bring about indexing of the bags in the chain through the bag filling system. The result is an economical and reliable zipper equipped bag filling method and apparatus.

Abstract: An apparatus is disclosed for making bag material having a bag wall sheet or film folded to provide a closed folded top for each bag, a zipper strip having a web being nested within the bag top fold and having the margins of the web carrying recloseable zipper profiles, and at least one of the margins remaining unattached relative to the bag wall.

Abstract: A dispenser for plastic bags comprises a container having a dispensing opening through which bags can be withdrawn seriatim from the container. The bags are stacked within the container and each lead bag has a trailing end connected by a line of weakened resistance to the leading end of the trailing bag so that when a lead bag is pulled through the opening, cooperating shoulders on the trailing bag at the ends of reclosable fastener assembly brake the container at the opening and cause the bags to separate at the weakened line. The separated trailing bag is disposed at the opening for subsequent convenient withdrawal. The bags may be stacked by top end-connected pairs within the container. Pressure sensitive adhesive retains the container on a support against displacement when pulling bags from the container. The container may carry a replaceable closure flap for the dispensing opening.

Abstract: A container dispenser assembly containing stacks of flat bags with their tops adjacent and releasably interconnected and held in a rectangular cardboard container having a central tear strip extending over three walls with the tear strip removable and the separated sections of the container foldable about a fourth wall. In one form a thread is anchored within the container to be drawn between the tops of the bags and separate them. When the container is folded open, the bags may be withdrawn one by one from the two halves of the container.

Abstract: A method and structure for a non-reopening extruded plastic profile fastener wherein complementary rib and groove type profiles are constructed and arranged to be pressed into interlocking relationship, and provided with restraining means against permanent interlocking so that the fastener can be handled as an assembly with the profiles aligned for interlocking but not interlocked until the means are overridden and the profiles pressed into interlocked relation with one form of the overridable means being a frangible diaphragm across the groove to prevent movement of the rib and in another form a projecting strut which is yieldable with the application of a predetermined force or which is removable to permit the profiles to be moved to fully interlocked position.

Abstract: A storage device for bags of selected width and wherein each of the bags has a top end portion with a rib extending thereacross and the rib being of greater thickness than the bag top end portion, the device comprising a member having a slot substantially as long as the bag width, the slot being narrower than the rib thickness but of a width which will freely receive the bag top portion thickness, and an entrance into the slot through which the top end portion of the bag can be slidably inserted for storage of the bag with the rib at one side of the slot and the remainder of the bag at the opposite side of the slot. The device may taken various desirable forms such as an upright display stand on which the bags can be stored in display orientation, or a storage drawer in which the bags are supported on a slotted drawer bottom panel.

Abstract: A carrier tape is provided comprising a longitudinally extending base strip and a generally coextensive cover strip. The strips are extruded of a plastic material with at least one of the strips being formed with an integral longitudinal profile and the other of the strips having surfaces thereon which engage the profile in a continuous mechanical interlock. The surfaces of the other strip may comprise a mating profile. At least one of the strips is provided with longitudinally spaced cavities for receiving products to be carried. The tape is also provided with spaced sprocket holes for driving the tape.

Abstract: Integrally serially connected top fillable bags have closed bottoms and sides and reclosable zippers from which pull flanges extend upwardly. The bags are separated along their sides including the pull flanges and continuous connecting strips connect the tops of the pull flanges and have guide ribs extending continuously therealong for engagement by supporting jaws which serve to open the serially connected bags one at a time at a filling station for filling. After the filling station, the filled bag is separated from the connected bags by removing the connecting strip from the tops of the pull flanges of the filled bags in line with or below the top ends of the separations between bags. The zipper of the filled bag is closed by a closing device such as pinch rolls through which the bag is pulled and the connecting strips removed.
