<p><P>PROBLEM TO BE SOLVED: To provide a container having a preferable strength, which can be easily and quickly manufactured. <P>SOLUTION: The container includes a body 10 made of paper and an adhesive thin film formed over the body. The body is provided with adhesive layers 20 made of a biodegradable plastic material in an outer peripheral portion of a bottom part or an outer peripheral portion of an upper end edge part of an annular piece 13. Moreover, the body is formed by combining a bottom plate 12 and the annular piece, and the container is formed by connecting the bottom plate with a lower edge of the annular piece. The bottom plate and the annular piece are correspondingly connected with each other via the adhesive layer. A slight portion of the edge parts are sequentially folded, and one of the adhesive layers is integrally formed in the upper end edge parts of the edge parts and corner portions formed between the adjacent edge parts. The adhesive layer is integrally formed up to the outer peripheral edge portions of the edge parts to form a reinforcing part, and an end of the reinforcing part extends downward to form a hook portion beyond an edge of the edge parts. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
