A manufacturing method of container, comprising the following steps: material blending: preparing a coating material by mixing and blending a binder and a thermo-expandable powder consisting of a plurality of thermo-expandable microcapsules, each thermo-expandable microcapsule consisting of a thermoplastic polymer shell and a low-boiling-point solvent wrapped by the thermoplastic polymer shell, the binder being selected from a group consisting of polyvinyl acetate resin, ethylene vinyl acetate resin, polyurethane resin and a mixture thereof; coating: coating the coating material on a part of an outer surface of a substrate of the container to form a coated layer, at least one non-coated portion being formed on the container, the non-coated portion being defined by the coated layer; and foaming: heating the coated substrate till the coated layer foaming so that the coated layer becomes a foam layer, the non-coated portion being thus defined by the foam layer instead; characterized by a step between the coating step and the foaming step: drying: drying the coated layer at a temperature lower than a foaming point of the thermo-expandable microcapsules so that the coated layer adheres to the container and becomes a non-sticky coated layer, and in that a figure is printed on the non-coated portion such that the foam layer has a printing figure, the figure of the non-coated portion and the figure of the foam layer are continuous. material blending: preparing a coating material by mixing and blending a binder and a thermo-expandable powder consisting of a plurality of thermo-expandable microcapsules, each thermo-expandable microcapsule consisting of a thermoplastic polymer shell and a low-boiling-point solvent wrapped by the thermoplastic polymer shell, the binder being selected from a group consisting of polyvinyl acetate resin, ethylene vinyl acetate resin, polyurethane resin and a mixture thereof; coating: coating the coating material on a part of an outer surface of a substrate of the container to form a coated layer, at least one non-coated portion being formed on the container, the non-coated portion being defined by the coated layer; and foaming: heating the coated substrate till the coated layer foaming so that the coated layer becomes a foam layer, the non-coated portion being thus defined by the foam layer instead; characterized by a step between the coating step and the foaming step: drying: drying the coated layer at a temperature lower than a foaming point of the thermo-expandable microcapsules so that the coated layer adheres to the container and becomes a non-sticky coated layer, and in that a figure is printed on the non-coated portion such that the foam layer has a printing figure, the figure of the non-coated portion and the figure of the foam layer are continuous. drying: drying the coated layer at a temperature lower than a foaming point of the thermo-expandable microcapsules so that the coated layer adheres to the container and becomes a non-sticky coated layer, and in that a figure is printed on the non-coated portion such that the foam layer has a printing figure, the figure of the non-coated portion and the figure of the foam layer are continuous.
