Abstract
Bags with reclosable zippers along their mouth ends and having pull flanges extending above the zippers, have attending upwardly from said pull flanges separably attached tamper evident extensions which are adhesively fixed to one another so that it is necessary to separate the tamper evident extensions from the pull flanges along lines of weakening when it is desired to gain access into the bag through the reclosable zipper. A method of and an apparatus for making the bags in linked chains and a method of and apparatus for filling the linked bags and then completing the filled bags are disclosed.
Claims18
A top filled bag having opposed wall panels defining a contents pouch closed along opposite sides and a bottom end, and comprising:
- an upper mouth portion of the bag having reclosable fastener means;
- pull flange portions of said wall panels extending upwardly from said fastener means;
- respective upward tamper evident extensions separably connected to said pull flange portions;
- and
- a line of adhesive means separately applied to the inner surface of each of said extensions and coacting for fixedly attaching said extension to one another, so that said tamper evident extensions must be detached from said pull flange portions for separating said pull flange portions and opening said fastener means for gaining access into said pouch.
A chain of top fillable bags integrally serially linked in partially separated relation with upper bag mouth portions of the bags having reclosable fastener zipper means and pull flange portions extending upwardly from the zipper means, and comprising:
- respective upward tamper evident extensions connected to the pull flange portions;
- adhesive means carried by at least one of said extensions for fixedly attaching the extensions together in tamper evident manner after the bags have been respectively filled;
- continuous guide strips extending upwardly from said extensions and linking the bags serially and having guide means thereon for permitting the linked bags to be drawn slidably through bag opening means in a filling apparatus;
- means detachably connecting said strips to said extensions;
- and
- said strips being removable from said extensions after the bags have been filled and said adhesive means then acting after the filling for fixedly securing the extensions to one another in tamper evident manner.
Top fillable bags integrally serially linked in partially separated relation with upper bag mouth portions of the bags having reclosable fastener zipper means, and pull flange portions extending upwardly from the zipper means, and comprising:
- respective upper tamper evident extensions connected to the pull flange portions;
- adhesive means on the inside surface of at least one of said extensions for fixedly attaching the extensions together in tamper evident manner after the bags have been respectively filled;
- continuous guide strips extending upwardly from said extensions and linking the bags serially;
- and
- guide means along the guide strips for permitting the linked bags to be drawn slidably through bag opening means in a filling apparatus.
