Containing Box Structure

Abstract

A containing box structure includes a containing box and a lid body. The lid body includes top and front lids. A notch is formed on the outward side of a predetermined corner or portion of the edge of a top opening of the containing box. Abutting portions extending from predetermined segments of the inward side of the edge of the top lid straddle at the edge of the top opening of the containing box, such that a hook portion extending downward from a predetermined corner or portion of the top lid gets engaged laterally with the notch of the containing box to effectuate positional restriction between the top lid and the containing box. Therefore, the containing box is covered, and thus is in precise positional engagement, with the top lid and the front lid.

What is claimed is: 
     
         1 . A containing box structure, adapted to contain objects therein, the containing box structure comprising:
 a containing box adapted to contain objects therein and having a top opening opening upward and a front opening opening forward; and   a lid body including a top lid and a front lid for covering the top opening and the front opening of the containing box, respectively, wherein a notch is formed on an outward side of a predetermined corner or portion of an edge of a horizontal segment of the top opening of the containing box, and abutting portions formed by extending an inward side of an edge of the top lid of the lid body by a predetermined segment straddle an upper edge of the containing box, such that a hook portion formed by extending a predetermined corner or portion of the top lid downward gets engaged laterally with the notch at the upper edge of the containing box, so as to effectuate a positional restriction between the top lid and the containing box and maintain a precise positional engagement between the containing box and the top lid and the front lid of the lid body when the containing box is covered with the top lid and the front lid of the lid body.   
     
     
         2 . The containing box structure of  claim 1 , wherein the abutting portions formed by extending by a predetermined length the inward side of the edge of the top lid of the lid body for covering the top opening of the containing box is of a same height as the outward side of a periphery of the lid body, such that the abutting portions straddle at the upper end of the containing box to maintain a tight contact therewith. 
     
     
         3 . The containing box structure of  claim 1 , wherein an inward side of an edge of the top lid of the lid body for covering the top opening of the containing box extends by a predetermined length to form an auxiliary rib for reinforcing the lid body when the containing box is covered with the top lid, so as to enhance tightness and stability of a positional engagement between the lid body and the containing box. 
     
     
         4 . A containing box structure, comprising a containing box for containing objects therein and a lid body for covering a top opening of the containing box, the lid body comprising a top lid and a front lid, and characterized in that:
 an engagement segment of a predetermined width is formed at a front edge of the top lid, a hole is formed at the top lid to penetrate the top lid and positioned on each of the two sides of the engagement segment, an abutting segment formed by extending an upper edge of the front lid is inserted into the engagement segment of the top lid, and a branch portion formed outwardly and protrudingly on each of the two sides of the abutting segment is inserted into the hole of the engagement segment, such that the front lid is pivotally coupled to the engagement segment of the top lid, wherein the front lid is lifted relative to the engagement segment of the top lid to reach an adjacent edge of the top lid and thus effectuate a positional anchorage, thereby rendering it easy to put objects in the containing box and take objects out of the containing box.   
     
     
         5 . The containing box structure of  claim 4 , wherein the abutting portions formed by extending by a predetermined length an inward side of an edge of the top lid of the lid body for covering the top opening of the containing box is of a same height as the outward side of a periphery of the lid body, such that the abutting portions straddle at the upper end of the containing box to maintain a tight contact therewith. 
     
     
         6 . The containing box structure of  claim 4 , wherein an inward side of the edge of the top lid of the lid body for covering the top opening of the containing box extends by a predetermined length to form an auxiliary rib for reinforcing the lid body when the containing box is covered with the top lid, so as to enhance tightness and stability of a positional engagement between the lid body and the containing box.
