Abstract
The disclosure pertains to a reclosable bag wherein the web or film is folded to form a top folded edge. This fold further creates the front wall and an upper portion of the rear wall. A zipper is sealed within the upper fold to the front wall and the upper portion of the rear wall. A bottom folded edge is formed thereby forming the lower portion of the rear wall. The upper and lower portions of the rear wall are joined by a fin seal. The upper folded edge gives the appearance of a seal, particularly if a sealing bar is used to seal portions of the front wall and the upper rear wall immediately adjacent to the top folded edge.
Description
- 1. Field of the Invention
- The present invention pertains to a reclosable plastic bag wherein the top is folded over to create the appearance of the sealing of two separate sheets of web to each other. This invention is particularly applicable when creating a shrouded appearance by inserting a slider and clip into the fold of a base web material.
- 2. Description of the Prior Art
- In the prior art, it is well known to create reclosable bags from sheets of film or web which are sealed together around the edges. This sealing around the edges has become, to at least some extent, expected by the consumer and is considered to be aesthetically pleasing.
- However, there are many advantages to a “zipper-in-the-fold” configuration which are disclosed in many patent references. Examples of such prior art include 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. and 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. In particular, in some applications and configurations, the “zipper-in-the-fold” embodiments are somewhat easier to control through the manufacturing machinery. However, heretofore, the “zipper-in-the-fold” configurations have had the web looped over the zipper without the aesthetically pleasing appearance of a seal above the zipper.
- It is therefore an object of this invention to provide a reclosable plastic bag which achieves the advantages of a “zipper-in-the-fold” configuration while maintaining an appearance similar to that of a top seal.
- This and other objects are attained by providing a reclosable bag wherein the base web is folded to form the top edge of the reclosable bag. A zipper, typically with a slider, is inserted and sealed into the fold, and apparent or “false” seal is formed at the fold. The resulting structure is fed into a wrapper wherein the product, such as foodstuffs, is introduced and the side seals and rear fin seal are formed. Typically, the side seals stop below the profiles, thereby eliminating the need for seal bar modifications to enable the seal bars to seal over the profile. This results in an aesthetically pleasing package which is easier to control through the manufacturing machinery.
- Further objects and advantages of the invention will become apparent from the following description and from the accompanying drawings, wherein:
-
FIG. 1 is a front view of a reclosable bag of the present invention. -
FIG. 2 is a cross-sectional view along plane 2-2 ofFIG. 1 . - Referring now to the drawings in detail wherein like numerals refer to like elements throughout the several views, one sees that
FIG. 1 is a front view ofreclosable bag 10 of the present invention whileFIG. 2 is a cross-sectional view. - A single sheet of web or
film 12 is folded or creased so as to form the top foldededge 14 ofreclosable bag 10 and further formingfront wall 16 and upperrear wall 18.Zipper 20, typically withinterlocking profiles slider 26 is inserted near or proximate to the top foldededge 14 andflanges interlocking profiles front wall 16 and upperrear wall 18 thereby formingtransverse flange seals Profiles zipper 20 typically terminate in end stops to preventslider 26 from running off the ends of thezipper 20. Additionally, top foldededge 14 can be impressed with seal bars to sealfront wall 16 to upperrear wall 18 to form sealedarea 44 immediately adjacent to top foldededge 14 which gives the further appearance of a seal. One or more lines of weakness, such as by perforations, laser scoring or other methods known to those skilled in the art, can be formed between sealedarea 44 andtransverse flange seals zipper 20. - Typically using a wrapper (not shown), contents (not shown) such as foodstuffs are placed into
reclosable bag 10 andfront wall 16 is then folded so as to form lower foldededge 46 and lowerrear wall 48. The edge of lowerrear wall 48 is then sealed to the edge of upperrear wall 18 thereby formingrear fin seal 50. Seal bars (not shown) then formside seals 60, 62 by joining the lateral edges offront wall 16 to lateral edges of upper and lowerrear walls side seals 60, 62 stop attransverse flange seals profiles profiles - Thus the several aforementioned objects and advantages are most effectively attained. Although a preferred embodiment of the invention has 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.
