Abstract
An easy opening bag comprising corner seals. A line of weakness extends from at least a portion of a first panel of the bag into at least a portion of a first corner seal of the bag, wherein the line of weakness is: a dashed line in the first panel; and a continuous line in the first corner seal, and wherein the dashed line in the first panel and the continuous line in the first corner seal abut.
Claims20
An easy opening bag (10), comprising a first panel (11), a second panel (12), a third panel (13), and a fourth panel (14),
- wherein said first panel (11) is:
- i) adjacent to said second panel (12) and said fourth panel (14);
- and ii) opposing to said third panel (13);
- wherein said second panel (12) is:
- i) adjacent to said first panel (11) and said third panel (13);
- and ii) opposing to said fourth panel (14);
- wherein each of said first, second, third, and fourth panels (11, 12, 13, 14) has a respective upper edge, lower edge, first side edge, and second side edge, wherein the first side edge and the second side edge are opposing;
- wherein the respective upper edges of said first, second, third, and fourth panels (11, 12, 13, 14) are sealed to form a top seal (15), the respective lower edges of said first, second, third, and fourth panels (11, 12, 13, 14) are sealed to form a bottom seal (16);
- wherein the second side edge of said first panel (11) is sealed to the first side edge of said second panel (12) to form a first corner seal (17);
- wherein the second side edge of said second panel (12) is sealed to the first side edge of said third panel (13) to form a second corner seal (18);
- wherein the second side edge of said third panel (13) is sealed to the first side edge of said fourth panel (14) to form a third corner seal (19);
- wherein the second side edge of said fourth panel (14) is sealed to the first side edge of said first panel (11) to form a fourth corner seal (20);
- and
- wherein a line of weakness (21) extends from at least a portion of said first panel (11) into at least a portion of said first corner seal (17), wherein said line of weakness (21) is:
- a dashed line (23) in said first panel (11);
- and a continuous line (22) in said first corner seal (17), and wherein said dashed line (23) in said first panel (11) and said continuous line (22) in said first corner seal (17) abut.
A process for making an easy opening bag containing a consumer product sealed therein comprising the steps of:
- a) moving a continuous web of film having a line of weakness, in a machine direction, wherein said web has a first edge and an opposing second edge;
- b) forming four corner seals in the web along said machine direction, wherein each of said four corner seals are separated by panel zones,
- wherein said line of weakness extends from at least one panel zone and through at least one corner seal adjoining said at least one panel zone, and wherein said line of weakness is:
- i) a dashed line in said at least one panel zone;
- and
- ii) a continuous line in the adjacent corner seal;
- c) sealing said first edge and second edge of the web, to form a tube with a fin seal;
- d) sealing said tube with said fin seal laterally to form a bottom seal in said tube;
- e) cutting said tube with said bottom seal laterally to define a bag having a circumferential edge, wherein said circumferential edge defines an opening into an internal volume of the bag;
- f) depositing the consumer product into the internal volume of the bag via said opening to provide a bag containing the consumer product composition;
- and
- g) sealing the bag containing the consumer product laterally to form a top seal in the bag thereby providing the easy opening bag containing the consumer product.
