Abstract
An apparatus for opening dual bag sets having pressure interlocking zipper profiles along the top with pull flanges extending upwardly from the profiles and a bridging pull flange joining adjacent bag pairs, dual flange gripping means for the outer pull flanges of each of the bags riding along a rib on the bag, with the gripping means mounted on pivotal handles so that after the bags are moved forwardly, they can be pulled open for filling by manually pressing the handles together with the handles provided with a return spring.
Claims16
An apparatus for opening and filling adjoining plastic bags having pressure interlocking zipper profiles along the top with pull flanges extending upwardly from the profiles and bridging flanges joining adjacent bags comprising in combination:
- flange gripping first means for gripping the outer pull flange of a closed zipper bag having a second bag connected thereto by a bridging flange;
- second means for gripping the outer pull flange of the second bag so that the bags can be opened by a lateral separation of said first and second means;
- pivot arms with said first means on one arm and the second means on the other arm;
- and
- a manually operated handle means connected to the arms so that movement of the handle will move the first means away from the second means to open the bags.
An apparatus for opening and filling sets of interconnected plastic bags having pressure interlocking zipper profiles along the top with said bags arranged in double form with a center pull flange interconnecting first and second bag sets and outer pull flanges extending upwardly from the profiles comprising in combination:
- first and second flange gripping means for respectively receiving the outer pull flange of said first and second bags;
- a continuous ridge for supporting a doubled bridging flange between said bags;
- pivotal arms supporting said first and second means at one side of the pivot;
- and
- manually operable handle means at the other side of said pivot so that said means can be simultaneously moved outwardly to open both of said bags for simultaneous filling.
An apparatus for opening and filling adjacent interconnected plastic bags having interlocking zipper profiles along the bag tops with pull flanges extending upwardly from the profiles and a bridging flange interconnecting the bags comprising in combination:
- a continuous supporting ridge for supporting the bridging flange between adjacent bags so that continuous bags can be drawn linearly therealong;
- first and second flange gripping means for receiving the outer pull flanges of each of the bags;
- movable arms each supporting the gripping means;
- and
- handle means connected to said movable arms for moving the gripping means between a first position adjacent each other and a spread position for drawing bag tops apart.
An apparatus for opening and filling sets of interconnected plastic bags having pressure interlocking zipper profiles along the top with pull flanges extending upwardly from the profiles and a bridging flange connecting dual bag sets and provided with ribs along the pull flanges comprising in combination:
- a continuous ridge having a smooth top for supporting the bridging flanges of interconnected bags;
- flange gripping first and second means gripping the outer flanges of each of the bags with each of said gripping means having spaced flange engaging members for opening a broad portion of the bag top;
- pivotal handles with gripping means at one end and a handle at the other end for manually moving the gripping means apart;
- and
- spring means connected to said handles for urging the gripping means together.
An apparatus for opening and filling adjacent interconnected plastic bags having interlocking zipper profiles along the bag tops with pull flanges extending upwardly from the profiles and a bridging flange interconnecting the bags comprising in combination:
- a continuous supporting ridge for supporting the bridging flange between adjacent bags so that continuous bags can be drawn linearly therealong;
- first and second flange gripping means for receiving the outer pull flanges of each of the bags;
- an arch above the supporting ridge holding said bridging flange in place on the continuous ridge;
- and
- first and second outer flange gripping means for receiving the outer pull flanges of each of the bags and drawing them outwardly to open the bags carried on the continuous ridge;
- said flange gripping means being carried on pivotally movable arms supported on said arch.
