Definitions

  • closure device usable for closing the open neck of the bag.
  • the closure device is located inside the bag and lightly held adhesively to the bag.
  • the closure device is thermo-sealed between the opposed lips of the mouth of the bag.
  • the closure device is adhesively attached along one edge thereof to the outside surface of the bag.
  • closure device is not used as a closure until the package passes into the hands of the consumer and the bag has been opened as by clipping from the bag the sealed end thereof which is indicated For Opening.
  • the closure device is referred to as a reclosure device.
  • Another object of the invention is to provide such a plastic bag in which the reclosure device is trapped in a pocket which is so formed on the bag as not to endanger a rupture of the bag itself in removing the reclosure device from said pocket.
  • Yet another object of the invention is to provide such a plastic bag in which there is relatively little danger of the closure device, or the means for securing the same to the bag, catching on other packages in a manner to cause a rupture of the bag or so as to detach any of the closure devices from the bags they are associated with.
  • a yet further object of the invention is to provide such a plastic bag having a reclosure device which will utilize for assembling the reclosure device with the bag a patch of the same material as the bag is made and the readily 3,519,196 Patented July 7, 1970 available method of heat sealing for associating said patch with the bag so as to form a pocket confining the reclosure facility in close association with the bag and without any reasonable prospect of being separated therefrom and yet in a manner to permit the ready manual separation of the reclosure device from the bag when a necessity for this arises.
  • FIG. 1 is a diagrammatic plan view of a preferred embodiment of the bag of the present invention showing the patch of the invention applied as by heat sealing to the bag thereof in the upper right hand corner of the bag and indicating in broken lines the outline of the closure device preferably employed in the invention, this being gapped in the pocket formed between said patch and said FIG. 2 is a side elevational view of FIG. 1.
  • FIG. 3 is a fragmentary enlarged sectional view taken on the line 3-3 of FIG. l and illustrates the structural details of the closure device holding pocket, which is a distinctive feature of the present invention, and shows in broken lines the manner in which said pocket is to be opened in order to remove the closure device.
  • FIG. 4 is a fragmentary perspective view illustrating the manner in which a preferred type of bag closure employed in the present invention is utilized in closing the plastic bag associated therewith.
  • the invention embraces a plastic bag 10 which is preferably made of sheet polyethylene or the like such as is commonly used in the making of bags for bagging bread, buns and the like and the bag may be of any construction and will be manufactured in various sizes to suit the needs of the customer using the same.
  • the bag 10 is of the type used to receive and hermetically seal a quantity of product for packaging the same for shipment to market.
  • the bag 10 thus is formed of a section of a tube, the lower end of which is closed by a heat seal 11 and the upper end of which is closed by a heat seal 12.
  • a patch 13 of plastic material which is thermoplastically compatible with the material of said tube (and preferably of the sa-me material as the tube) is applied to the tube and secured thereto in overlapping relation with a bag closure device 14 by the formation of a rectangular heat seal 15 to produce a pocket within the confines of said seal, and between said plastic tube and said patch, in which said closure device is confined.
  • the patch 13 preferably is provided, near one end thereof, with a slot 16 which is too small to have a tendency to snag on other packages which the bag 10 may lbe pressed against in packing and handling the same but will be large enough for the entrance of a finger nail into the slot whereby the plastic material o'f the patch 13 may Ibe engaged and torn lengthwise of the patch to readily provide an opening through which the device 14 may be removed when the time comes for using the same.
  • the Ibag closure device 14 which is preferably employed in the present invention is the widely known bag closure manufactured under the trademark Kwik Lok by the Kwik Lok Corporation of Yakima, Wash., and comprises a fiat, stiff, but springy clip formed of sheet polystyrene of about .030 inch thickness and having a central bag neck capturing aperture 19 admission to which 3 is had through a narrow slit or edge opening 20 which divides the adjacent edge 21 of the closure to form jaws 22 and 23 which may be flexed apart in applying the closure to the twisted neck of a bag 10 so that said jaws will separate and pass around said neck and trap the latter in the aperture 19.
  • Kwik Lok by the Kwik Lok Corporation of Yakima, Wash.
  • the patch 13 will be applied to the tube utilized in forming the plastic bag 10 while said bag is in flat form, and which means prior to the lling of the bag with a product to be packaged therein.
  • sheet polyethylene has been indicated as a suitable material for use in the manufacture of the plastic bag 10 and patch 13 of the present invention, it is to be understood that the invention is not limited to this specific material and that any of the many chemical and physical equivalents of this material in the plastic eld may be utilized for manufacturing these elements of the invention.
  • the patch 13 is preferably secured to the bag 10 by a rectangular heat seal 15, it is not essential that this heat seal comprise a continuous rectangle so long as it is serviceable in forming a pocket which will conne the closure device 14 in close association with the bag 10 until the purchaser of the product packaged in the bag undertakes to deliberately open the patch and remove the closure therefrom.
  • the invention is not limited to any particular shape of patch in forming the patch 13 or any particular shape in the heat seal 1S providing that these two elements accomplish the pocketing 0f the bag closure device.
  • a plastic bag associated with a bag neck closing device and having a pocket formed by the application of a patch of plastic material to the outside of said bag, said patch being peripherally Welded to the outside of the bag to form a pocket between said bag and said patch in which said bag closure is confined.
