1. Field of the Invention
The present invention relates to reclosable bags, formed by a horizontal form fill seal (HFFS) process, with zippers, particularly slider zippers in a fin seal.
2. Description of the Prior Art
In the prior art, reclosable bags with a shrouded zipper or a zipper-in-the-fold configuration are well known. Examples of such prior art include U.S. Pat. No. 6,799,890 entitled “Tamper Evident Resealable Packaging”, issued on Oct. 5, 2004 to Schneider et al.; U.S. Pat. No. 6,347,437 entitled “Zipper and Zipper Arrangements and Methods of Manufacturing the Same”, issued on Feb. 19, 2002 to Provan; and U.S. Pat. No. 6,138,439 entitled “Methods of Making Slide-Zippered Reclosable Packages on Horizontal Form-Fill-Seal Machines”, issued on Oct. 31, 2000 to McMahon et al.
While these references have been satisfactory in many respects, it is desired that these configurations be modified to include the zipper in a fin seal, or to include a fin seal along with a zipper-in-the-fold configuration.
It is therefore an object of the present invention to provide a reclosable bag, formed by a form fill and seal method and apparatus, wherein the zipper profile is placed in a fin seal.
It is therefore a further object of the present invention to provide an alternative embodiment of a reclosable bag, with both a zipper-in-the-fold configuration along with a fin seal.
It is therefore a still further object of the present invention to achieve these objects within the context of known and established form fill and seal apparatus, particularly horizontal form fill seal apparatus.
These and other objects are attained by providing a reclosable bag wherein the profile and slider are in the fin seal, particularly with the fin seal in a central location on the front wall of the reclosable bag. The profile and slider can be sealed to make the resulting reclosable bag have the profile and clip exposed. Similarly, it could be sealed so that the reclosable bag has the profile and clip shrouded or otherwise sealed into the fin seal. This reclosable bag may also incorporate an easy open configuration by utilizing such methods as perforating, laser scoring, lines of weakness, etc. Further, this can be applied to other zipper styles, such as string zippers or flanged profile zippers.
An alternative embodiment includes the zipper and slider in the top fold with a fin seal formed at a central location in the front wall. By using established form fill and seal apparatus, slider packages can be produced and further can be made in what are known as quarter-fold and center-fold styles.
Further objects and advantages of the invention will become apparent from the following description and from the accompanying drawings, wherein:
Referring now to the drawings in detail wherein like numerals refer to like elements through the several views, one sees that
In the case of the embodiment of
Thus the several aforementioned objects and advantages are most effectively attained. Although preferred embodiments of the invention have been disclosed and described in detail herein, it should be understood that this invention is in no sense limited thereby and its scope is to be determined by that of the appended claims.
