Description

TECHNICAL FIELD The present invention relates to a container suitable for storing food and the like. BACKGROUND ART Conventionally, as illustrated in Patent Literature 1 and Patent Literature 2, erectable-type containers have been provided. Since the erectable-type containers can be kept compact until use, it is convenient without being bulky in transportation, inventory management and the like. CITATION LIST Patent Literature Patent Literature 1: JP 2011-116455 APatent Literature 2: JP 3133835 U SUMMARY OF INVENTION Technical Problem However, when food is placed in the container, moisture and oil tend to seep out of the container from a joint of a member since most of the foods contain moisture and oil. Therefore, there is a demand for a container that can preventing the moisture and oil contained in contents from seeping out or leaking out of the container. Thus, an object of the present invention is to provide an erectable-type container having excellent, durability. Solution to Problem A food container according to the present invention includes a bottom part, and a side part forming a box-shaped storage with the bottom part, and a cross section appearing on a periphery of the bottom part is sealed with an insoluble sealing material which prevents moisture infiltration, and the side part is adhered to the bottom part by adhesive or the sealing material interposed between the cross section appearing on the periphery of the bottom. Further, the bottom part may be circular, and the side part may be annular. Further the side part may be formed by engaging a belt-shaped body having a first engagement on one end and a second engagement on another end. Further, the first engagement and the second engagement may be adhered at a part to engage by an adhesive. Further, the side part may be tapered so as to expand a diameter in a direction opposite to the bottom part. Further, the container may be made of a woody material. The side part may be adhered to the bottom part so that a fiber direction of the woody material is parallel to the bottom part. Effect of the Invention According to the container of the present invention, even the food or the like containing water or oil is stored, the water or oil of the food does not seep out or leak out of the container, and the container has excellent durability. BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is an external perspective view illustrating a container according to a first embodiment of the present invention. FIG. 2 is an exploded perspective view illustrating a container according to a first embodiment of the present invention. FIG. 3 is a partially enlarged view schematically illustrating a joint part of a container according to a first embodiment of the present invention. FIG. 4 is a cross-sectional view illustrating a state in which containers according to a first embodiment of the present invention are covered with lids and stacked. FIG. 5 is an exploded perspective view illustrating a container according to a first embodiment of the present invention. FIG. 6 is an external perspective view illustrating a state in which containers according to a second embodiment of the present invention are stacked. FIG. 7 is a partially enlarged view schematically illustrating a joint part of a container according to a second embodiment of the present invention. FIG. 8 is an exploded perspective view illustrating a container according to a third embodiment of the present invention. PREFERRED EMBODIMENT First Embodiment A container according to an embodiment of the present invention will be described below with reference to the drawings. As illustrated in FIG. 1 and FIG. 2, the container according to a first embodiment of the present invention includes a bottom part 11 and a side part 12, bonded to each other. The bottom part 11 and the side part 12 forms a concave storage 1a having an upper opening, and contents such as food and the like are contained in the storage 1a. The bottom part 11 is a circular bottom plate and forms a box-shaped storage 1a with the side part 12. The bottom part 11 has a thickness capable of withstanding a weight of contents such as food stored in the storage 1a. Further, the bottom part 11 may be formed by a single flat plate-like bottom plate, or may be formed by stacking a plurality of bottom plates. The side part 12 forms the box-shaped storage 1a with the bottom part 11. This side part 12 is a belt-shaped body having an engagement protrusion 121 as a first engagement on one end and an engagement recess 122 as a second engagement on another end. By engaging the engagement protrusion 121 with the engagement recess 122, while bending entirely, the side part 12 is formed into an annular or cylindrical shape. As described below, the side part 12, for example, is made of woody material and has flexibility. Thus, when the engagement protrusion 121 and the engagement recess 122 are not engaged with each other, it can be stored as a flat belt-like member. On th
