Abstract
Zigzag-shaped pouches are formed from flexible web material by positioning two portions of the web material in overlying relation and sealing them together along top, bottom, and opposite side edges of the pouch. The side edges of the pouch are made up of a plurality of linear segments connected end-to-end and alternately inclined in opposite directions to form a zigzag-shaped edge. Each linear segment of one edge is substantially parallel to a corresponding segment of the opposite edge, such that the two edges are substantially complementary in shape, whereby the pouch as a whole has a zigzag shape.
Claims8
A flexible package comprising:
- two portions of flexible sheet material arranged in opposing relation and sealed together along edges of the sheet material to form a sealed interior space in the package, said edges including opposite first and second lateral edges, wherein the first lateral edge comprises linear segments connected end-to-end and alternately inclined in opposite directions such that the first lateral edge is generally zigzag-shaped, the second lateral edge comprising linear segments equal in number to the segments of the first lateral edge and respectively opposite from and substantially parallel to the linear segments of the first lateral edge such that the second lateral edge is generally zigzag-shaped, wherein each lateral edge has from 3 to 8 linear segments, whereby the first and second lateral edges are substantially complementary in shape to each other such that the package as a whole has a zigzag shape.
