<p>The present invention relates to a retractable food case capable of drawing out granular food one by one. An upper case is fitted in a lower case for storing food. A head part is formed in one end of the lower case to be fitted in the upper case. Protrusion sills and hung parts are formed on circumferential walls engaged to each other while protruded rails and rail sills are formed on the upper and lower cases to be slid. The upper and lower cases are slid by forming protrusions sills and hung parts on circumferential walls engaged to each other while protruded rails and rail sills are formed on the upper and lower cases to be slid; thereby being assembled by the self elastic force of plastics, conveniently opening and closing the case, and making the container slim. Also, both side walls of the lower case are respectively divided into an erected wall and an inclined wall to reinforce the circumferential walls. Boundary sills are formed in the boundary portions. Auxiliary protrusion sills corresponding to the boundary sills are formed on the upper case to set a slide section while preventing the lower case from being arbitrarily pulled out. Thus, the deformation of the upper and lower cases caused in a cooling process after a molding process even through the upper and lower cases are plastic-injection molded is minimized; thereby obtaining uniform quality.</p> |
