Embodiment Construction

[0031]FIG. 3A is a schematic diagram illustrating a mesh bag 31 with an easy-open end 32 according to a typical embodiment of the present invention. A piece of annular plastic membrane or film 35 is moulded or integrated with the top end of the mesh bag 31. The primary purpose of the membrane or film 35 is to avoid ventilation when a packaging machine is to open the top end by sucking. There are two pairs of punch holes 34 on the membrane or film 35 for setting the mesh bag on the holders of the packaging machine. The bottom end of the mesh bag is sealed or seamed with a line easy-open stitches which constitutes an easy-open mechanism 32.

[0032]In operation, the packaging machine sucks the two folded sides of the membrane or film 35 apart such that the top end of the mesh bag 31 opens its mouth from which the onions or the like are inputed into the mesh bag 31. After the mesh bag 31 is filled with onions or the like, it is sealed or seamed by sewing with a line of stitches across the...

Abstract

The invention teaches a new type of mesh bag suitable for machine packaging. The first end of the mesh bag is a reserved opening for filling and sealing. The second end of the mesh bag includes a one-pull, easy-open mechanism and a re-closing mechanism. The re-closing mechanism is a drawstring perforating around the second end of the mesh bag. The one-pull, easy open mechanism is a line of easy open stitches which sews a small strip of hard paper with the wall of the mesh bag at its second end. The two mechanisms can be pre-set in parallel or integrated in a same line with the small strip of the hard paper overlaid on the drawstring.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field of the Invention[0002]The present invention generally relates to the field of designing and manufacturing of packaging bags such as woven bas or mesh bags for containing fruits, nuts or produce. More particularly, the invention relates to a packaging bag with an easy-open and re-closable end other than the end with an opening for filling and sealing.[0003]2. Description of the Related Art[0004]Mesh bags have been widely used in commercial packaging and storing, laundry, as well as sports. More particularly, light weight and heavy duty mesh bags are widely used for containing and storing fruits, nuts, onions, garlic, and etc.[0005]Traditionally, there are two ways to seal the opening of the mesh bag. FIG. 1A is a schematic diagram illustrating a mesh bag 11 according to the prior art. The bottom end of the mesh bag 11 is sealed with a line of stitches 13 or other kind of sealing which constitutes a bottom, i.e., a dead end, to avoid...
