Abstract
The disclosure relates to a zipper design, with or without a leading flange, to improve front panel zipper fabrication and end use applications. The profiles of the zipper include a plurality of interlocking elements, which may include C-shaped, J-shaped or repeating male interlocking elements. In the unflanged version, a portion of the interlocking elements of one of the profiles is sealed directly to the interior of a bag on a first side of the front panel bag opening, while the base of the other profile is sealed on a second side of the front panel bag opening, aligned so that interlocking elements of one profile can interlock with interlocking elements of the other profile.
Description
- 1. Field of the Invention
- This invention pertains to a zipper design, with or without a leading flange, to improve front panel zipper fabrication and end use applications.
- 2. Description of the Prior Art
- In the prior art of reclosable bags, front panel pouches are well-known. Examples include U.S. Pat. No. 5,951,453 entitled “Reclosable Bag Assembly and Method of Making Same”, issued on Sep. 14, 1999 to Yeager and U.S. Pat. No. 6,270,257 entitled “Reclosable Bag with Profile Strip Fastener Assembly Having Improved Opening Feature”, issued on Aug. 7, 2001 to Yeager.
- Likewise, in the prior art of zippers for reclosable bags, it is known to design profiles which can interlock with similar profiles in various different alignments. Examples of this are disclosed in U.S. Patent Publication No. US-2003-0101552-A1, entitled “Variable Alignment Zipper for Reclosable Bags”, published Jun. 5, 2003 listing inventors Eric P. Plourde and Kevin P. Olechowski and U.S. Pat. No. 6,217,215 entitled “Closure Mechanism Having a Perceptible Feedback System”, issued on Apr. 17, 2001 to Tomic.
- While these references disclose devices which have been satisfactory in certain respects, it is desired to obtain further improvements in front panel zipper fabrication and end use applications.
- It is therefore an object of the present invention to provide a zipper for a reclosable bag which provides improvements in front panel zipper fabrication.
- It is therefore a further object of the present invention to provide a zipper for a reclosable bag which provide improvements in end use applications.
- These and other objects are attained by providing a zipper which can have a flanged or unflanged (otherwise known as webless or monotreme) embodiment. The interlocking profiles of the zipper include a series of interlocking elements, such as C-shaped elements terminating at both ends in an inwardly pointing hook configuration, J-shaped elements or multiple male elements. This allows the profiles to engage each other easily and form a strong interlocking configuration.
- For use in a front panel opening bag, typically a portion of the interlocking elements of a first profile are sealed to the interior of the web of the bag on a first side of the opening so that the remaining interlocking elements face outwardly while the base of a second profile is attached to the interior of the web of the bag via a sealant layer on a second side of the opening so that the interlocking elements face inwardly toward similar elements of the first profile. In the flanged configuration, it is the flange of the first profile which is bonded to the web of the bag. In the unflanged configuration, as a portion of the interlocking elements of the first profile is bonded to the film, material with a very high melting index is required for the profiles.
- In one configuration, a peel seal is added between the profiles.
- 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 the reclosable bag with an unflanged embodiment of the zipper, of the present invention. -
FIG. 2 is a cross-sectional view of plane 2-2 ofFIG. 1 . -
FIGS. 2 a and 2 b are alternative cross-sectional views of plane 2-2 ofFIG. 1 . -
FIG. 3 is a cross-sectional view of the profiles, immediately prior to interlocking, of the unflanged embodiment of the zipper, including C-shaped interlocking elements. -
FIG. 4 is a cross-sectional view of the profiles, after interlocking, of the unflanged embodiment of the zipper, including C-shaped interlocking elements.. -
FIG. 5 is a cross-sectional view of the profiles, after interlocking, of the flanged embodiment of the zipper, including C-shaped interlocking elements. -
FIG. 6 is a cross-sectional view of the profiles, after interlocking, of a further embodiment with a single flange on each profile, including C-shaped interlocking elements. -
FIG. 7 is a cross-sectional view of the profiles, after interlocking, of a still further embodiment wherein one profile includes one flange and the other profile includes two flanges, including C-shaped interlocking elements. -
FIG. 8 is a cross-sectional view of the profiles, after interlocking, of yet a further embodiment with a single flange on each profile and a peel seal between the profiles, including C-shaped interlocking elements. -
FIG. 9 shows the zipper placed on the web in the transverse direction during manufacture. -
FIGS. 3 a-8 a correspond toFIGS. 3-8 , respectively, with multiple male interlocking elements in place of C-shaped interlocking elements. -
