Recloseable bag

Abstract

The invention relates to bag (10) comprising a line of weakness (28) for ease of opening, and a reclosing means (32), wherein the bag (10) comprises a front panel (12), back panel (14) and opposing side panels (16, 18), the panels being sealed together to provide a top section (24) and a bottom section (26), and wherein the line of weakness (28) extends around all of the front (12), back (14) and side (16, 18) panels so that the top section (24) is completely removable from the rest of the bag, and wherein the reclosing means (32) is attached to the front (12), back (14) and side (16, 18) panels adjacent to the line of weakness (28).The invention also relates to process for forming bags (10) from a web of film (30), wherein the web of film (30) is transported along one or more machines, the process comprising the steps of:(a) providing a line of weakness (28) across substantially the whole width of the film substantially in the cross-machine direction,(b) affixing reclosing means (32) adjacent to the line of weakness;(c) cutting and sealing the film to form a bag (10) comprising the line of weakness (28) and the reclosing means (32).

Description

FIELD OF THE INVENTION[0001]This invention relates to bags for use in storing products such as but not limited to powdered or granular detergent, pet food, coffee, cereal etc., wherein the bag has a line of weakness, which provides for easy opening of the bag, and a re-closing means.BACKGROUND OF THE INVENTION[0002]Flexible bags are used today to package a wide variety of consumer products including granular detergents.

AI Technical Summary

Problems solved by technology

First, current bags are difficult to open without the aid of scissors, a knife or other utensil.

Often times the consumer attempts to rip open the bag, with the end result being that the contents are spilled out.

Additionally, the bag and any text printed on the bag, can become distorted by the pulling and stretching of the opening action.

Second, once opened, current detergent bags offer no efficient and effective means of re-closing the bag.

Until now methods for re-closing such bags have been unsatisfactory.

The main drawback of the aforementioned methods is that contamination of the re-closing means with the contents of the bag prevents the means from forming a reliable, re-usable seal.

Additionally, simple folding mechanisms provide no protection from product leakage.
