ABSTRACT:
FIELD
The present invention generally relates to closure arrangements for packages. In particular, the present invention relates to closure arrangements having reclosable profiles and slider devices to open and close the profiles.
BACKGROUND
Many packaging applications use resealable containers to store various types of articles and materials. These packages may be used to store and ship food products, non-food consumer goods, medical supplies, waste materials, and many other articles.
Resealable packages are convenient in that they can be closed and resealed after the initial opening to preserve the enclosed contents. The need to locate a storage container for the unused portion of the products in the package is thus avoided. As such, providing products in resealable packages appreciably enhances the marketability of those products.
Slider devices have been used to help open and close closure profiles on reclosable bags. In some instances, the slider devices can be ejected from the reclosable bag when the bag is open and the sides of the bag are pulled outwardly. Improvements in closure arrangements are desirable.
SUMMARY OF THE DISCLOSURE
In one aspect, the disclosure describes a flexible package including a package surrounding wall having a side edge and a mouth. A recloseable zipper is provided along the mouth for selective opening and closing of the mouth. The zipper includes first and second closure profiles. A slider device is provided to selectively open and close the mouth. A first seal region and a second seal region are provided on the flexible package. The first seal region permanently secures together first and second flanges of first and second closure profiles. The second seal region permanently secures together the first and second closure members of the first and second closure profiles and has an end edge. The length of the second seal region is at least 25% of the length of the slider device.
In one embodiment, the second seal region is a continuous, uninterrupted extension from the side edge to the end edge.
In another embodiment, the second seal region comprises first and second seal sections separated by a gap.
Methods of sealing and operation are provided.
The above summary is not intended to describe each illustrated embodiment or every implementation of the present invention. The figures and the detailed description that follow more particularly exemplify these embodiments.
