Abstract:
[Problem] The purpose of the present invention is to provide a method for manufacturing a paper container in which creasing of the container surface does not readily occur and which has curved surfaces provided with a bottom rim. [Solution] A method for manufacturing a paper container having paper as the primary material, at least the inner-surface side of the container being provided with a thermoplastic resin, and the paper container comprising a body member and a bottom member, wherein the method for manufacturing a paper container is characterized by including: a body member forming step for forming the body member so as to have a tubular shape or a reverse truncated-cone shape in which the upper-end part and the lower-end part of the body member are free; a joining part forming step for bending the outer-peripheral edge of the bottom member so as to have a high-rimmed dish shape, folding the lower-end part of the body member inward so as to sandwich the outer-peripheral edge of the bottom member, and performing thermal pressure-bonding to form a joined part. The bottom-surface part of the bottom member is recessed so as to protrude downward beyond the joined part. FIG. 1
