Claims
- 1. A boil-in-bag sachet for rehydrating a food product by immersion in water comprising a tubular pouch formed from a water-permeable perforated film, a top and bottom edge, coplanar side edges, and separate top and bottom transverse seals, the bottom transverse seal including a diagonal portion extending downwardly and inwardly from at least one side edge and a horizontal portion extending across a central portion of the bottom edge of the sachet, the sachet having a central longitudinal axis, whereby the diagonal portion of the bottom transverse seal facilitates drainage of water through the perforated film while preventing a portion of the food product from being trapped along the transverse seals when the sachet is removed from the water.
- 2. A boil-in-bag sachet according to claim 1, wherein the diagonal portion extends downwardly and inwardly from both side edges of the sachet.
- 3. A boil-in-bag sachet according to claim 1, wherein the bottom transverse seal extends across a corner of the sachet, thereby defining a corner-tab for handling the sachet.
- 4. A boil-in-bag sachet according to claim 1, wherein the bottom transverse seal is symmetrical about a central longitudinal axis of the sachet.
- 5. A boil-in-bag sachet according to claim 1, wherein the bottom transverse seal intersects at least one edge of the sachet at an angle of 20° to 70° to the longitudinal axis of the sachet.
- 6. A boil-in-bag sachet according to claim 5, wherein the bottom transverse seal intersects at least one edge of the sachet at an angle of 45° to the longitudinal axis of the sachet.
- 7. A boil-in-bag sachet according to claim 1, wherein the boil-in-bag sachet includes a pair of longitudinal lines of weakness extending from the top transverse seal to the bottom transverse seal and defining at least one tear strip in the sachet.
- 8. A boil-in-bag sachet according to claim 7, wherein the boil-in-bag sachet has two pairs of longitudinal lines of weakness extending from the top transverse seal to the bottom transverse seal and defining two tear strips in the sachet.
- 9. A boil-in-bag sachet according to claim 7, wherein the lines of weakness of each said pair extend parallel to each other on opposite sides of the sachet and adjacent to the two edges of the sachet.
- 10. A boil-in-bag sachet according to claim 7, wherein the lines of weakness include a nip proximate to their top end.
- 11. A boil-in-bag sachet according to claim 10, wherein the nip is a V-shaped cut-out.
- 12. A boil-in-bag sachet according to claim 7, wherein the lines of weakness have a nip proximate to their bottom end.
- 13. A boil-in-bag sachet according to claim 12, wherein the nip is a substantially V-shaped cut-out.
- 14. A boil-in-bag sachet (1) according to claim 7, wherein the lines of weakness are lines of perforations.
- 15. A boil-in-bag sachet according to claim 1, further comprising a second transverse top seal longitudinally spaced from the first transverse top seal, and wherein the boil-in-bag sachet is further provided with a fork slot between the first and second transverse top seals.
- 16. A boil-in-bag sachet according to claim 1, wherein the boil-in-bag sachet is formed from a single web of film material.
- 17. A boil-in-bag sachet according to claim 1, wherein the sachet is formed from a thermoplastic film and the top and bottom transverse seals comprise impulse seals or heat seals.
- 18. A boil-in-bag sachet according to claim 1, wherein the sachet contains a rehydratable food product.
- 19. A boil-in-bag sachet for rehydrating a food product by immersion in water comprising a tubular pouch formed from a water-permeable perforated film, a top and bottom edge, coplanar side edges, and separate top and bottom transverse seals, the bottom transverse seal including a diagonal portion extending downwardly and inwardly from each side edge whereby the diagonal portion of the bottom transverse seal facilitates drainage of water through the perforated film while preventing a portion of the food product from being trapped along the transverse seals when the sachet is removed from the water.
