Kind Code:
A1
Abstract:
Provided is a method of manufacturing a tetrahedron-shaped extraction bag, in which first lateral seals and second lateral seals are alternately formed by alternately welding and fusion-cutting an extraction bag sheet (5) formed in a cylindrical body in the directions crossing each other when viewed from above, and the interior of the extraction bag sheet of the cylindrical body is filled with contents during formations of the first lateral seals and the second lateral seals are alternately repeated. According to the method, a flexible sleeve (90) is disposed on the upstream side of positions where the first and second lateral seals are formed and inside the cylindrical body (5b) of the extraction bag sheet so as to form each lateral seal, whereby a tetrahedron-shaped extraction bag having no wrinkles at the seal portions can be manufactured.
