Abstract
A bag (10) having an inwardly disposed seam is manufactured from a sheet of plastic bag material having two major surfaces and two parallel side edges. A first seam (24) seals the two parallel side edges together at the same major surface with the side edges disposed inwardly of the tube to form the sheet of plastic bag material into a tube with internal flap portions (20, 22) extending interiorly of the tube. At least one seal across the tube is provided for forming at least a three-sided bag structure (and preferably two seals across the tube for forming a closed four-sided bag structure) whereby pressure in the interior of the bag acts against the internal flap portions disposed inwardly of the tube to enhance the sealing of the seam. The bag is filled at an opening defined along the opposite side edges of the seam facing inwardly of the tube.
Claims
1. 1. A bag having an inwardly disposed seam with a self sealing opening
2 comprising in combination:
3 a sheet of plastic bag material having first and second major surfaces and two
4 parallel side edges;
5 the sheet of plastic bag material formed into a tube with a first maj or surface
6 of the plastic bag material on the exterior of the tube and the second major surface of the
7 plastic bag material on the interior of the tube;
8 a first seam joining the two parallel side edges together at the first major
9 surface with the two parallel side edges disposed inwardly of the tube to form the sheet of 0 plastic bag material into a tube with internal flap portions extending interiorly of the tube; 1 at least two seals across the tube for forming a four-sided bag structure having 2 a sealed interior; and, 3 an opening defined along the first seam interrupting the seam at the first major 4 surface with the two parallel side edges adjacent the opening disposed inwardly of the four 5 sided-bag to form an internal flap structure adjacent the opening; 6 whereby pressure in the interior of the bag acts against the internal flap 7 portions at the second major surface of the sheet of plastic bag material adjacent the opening 8 and disposed inwardly of the four sided bag structure to cause the internal flap portions to 9 move into a sealed relationship to seal the opening defined along the first seam,
1 2. The bag having the inwardly disposed seam according to claim 1 and
2 wherein:
3 the tube is folded inwardly to form inwardly folded gussets.
1 ' 3. The bag having the inwardly disposed seam according to claim 2 and
2 wherein:
3 the first seam is disposed at an inwardly folded gusset,
1 4. The bag having the inwardly disposed seam according to claim 3 and
2 wherein:
3 the first seam is disposed at the inward fold of the inwardly folded gusset.
1 5, The bag having the inwardly disposed seam according to claim 1 and
2 including: at least one second seam configured at the opening at substantial right angles to the first seam, extending at least from the first seam joining the side edges, disposed inwardly of the bag to form a joinder at the internal flap portion for closing the opening responsive to pressure in interior of the bag,
6. The bag having the inwardly disposed seam according to claim 5 and including:
the second seam is angularly disposed with respect to the first seam to form an opening of variable cross section.
7. The bag having the inwardly disposed seam according to claim 5 and including: the second seam is angularly disposed with respect to the first seam to form an opening of decreasing cross section from the first seam along the side edges disposed inwardly of the tube,
8. The bag having the inwardly disposed seam according to claim 5 and including:
two second seams are configured at the opening at substantial right angles to the first seam.
9. The bag having the inwardly disposed seam according to claim 8 and including: the two second seams converge from the first seam to provide the opening a large section at the first seam to a smaller section interior of the bag along the internal flap portions.
10. The bag having the inwardly disposed seam according to claim 5 and including: the second seam is configured adjacent to a seal across the tube.
11. The bag having the inwardly disposed seam according to claim 10 and including: a line of perforations disposed adjacent to a seal across the tube, whereby stress dimples are eliminated adjacent to the opening.
12. The bag having the inwardly disposed seam according to claim 11 and wherein: the line of perforations is disposed adjacent to a second seam; the line of perforations is separated; and, the side edges disposed inwardly of the tube are pulled from the disposition interior of the bag to a disposition exterior of the bag to form a pouring spout for the contents of the bag.
13. The bag having the inwardly disposed seam according to claim J and including: solid contents filling the bag to form pressure in the interior of the bag to act against the side edges disposed inwardly of the tube, to enhance the closure of the first seam,
14. The bag having the inwardly disposed seam according to claim 1 and including: a conduit disposed within the opening from the exterior of the bag to the interior of the bag for filling the bag.
15. The bag having the inwardly disposed seam according to claim 15 and including: a tapered conduit is disposed within the opening from the exterior of the bag to the interior of the bag for filling the bag.[Consider this wording: a tapered conduit disposed within the opening from the exterior of the bag to the interior of the bag for filling the bag.
16. The bag having the inwardly disposed seam according to claim 14 and including: retaining means acting between the conduit and the bag at the opening in the first seam for maintaining the bag at the opening to the conduit.
17. The bag having the inwardly disposed seam according to claim 7 and including: a tapered conduit having a smaller forward-most end and a larger rearward end is disposed wittύn the opening of the decreasing cross section from the first seam along the side edges into the interior of the tube; and,
21 „ the bag opening is placed over the smaller forward-most end and held up tight to the larger rearward end to fit snugly along a portion of the tapered conduit.
.
18. The bag having the inwardly disposed seam according to claim 1 and including: the first seam joining the two parallel side edges together is disposed along a . ' top edge of the bag.
19, The bag having the inwardly disposed seam according to claim 1 and including: an extended adjacent portion along an edge of the bag includes a die-cut handle for carrying the bag.
20. A process of filling a bag having an inwardly disposed seam comprising the steps of: providing a bag manufactured fio plastic sheet having two major surfaces and two parallel side edges and including, a first seam j oining two parallel side edges together with side edges disposed inwardly of the bag; at least two seals across the tube for forming a four sided bag structure; whereby pressure in interior of the bag acts against the side edges disposed inwardly of the bag to close the seam; providing an opening defined along the first seam; pro iding a conduit; fitting the conduit into the opening; filling the bag through the conduit and the opening to exert pressure on the inside of the bag, whereby pressure in the interior of the bag acts at the first seam and opening to enhance closure of the first seam and opening.
22
21. The process of filling a bag having an inwardly disposed seam comprising the steps of claim 20 including: mounting a plurality of the provided bags in side-by-side relation with their provided openings aligned with respect to one another; and, sequentially fitting the conduit into the openings of the bags to sequentially fill the bags through the conduit.
.
22. The process of filling a bag having an inwardly disposed seam comprising the steps of claim 20 wherein: the provided opening tapers from a large opening at the seam to a smaller opening interior of the two parallel side edges; and, the provided conduit correspondingly tapers from a large section adjacent to the large opening at the seam to a smaller section adjacent to the smaller opening interior of the two parallel side edges.
23 , The process of filling a bag having an inwardly disposed seam comprising the steps of claim 20 wherein: providing a vent communicated to the bag for venting air during filling of the bag,
24. The process of filling a bag having an inwardly disposed seam comprising the steps of claim 23 wherein: the provided vent is configured within the bag.
