Tube packaging box

Abstract

A tube packaging box is generally in the form of a box having an open top. The box includes a front board, a rear board, a bottom board, and two side boards such that the boards collectively form a rectangular receiving space. The front board is connected to a folding board. The folding board is extended to form a first folding section and a second folding section. With a tube positioned in the receiving space, the folding board is folded inwardly into the receiving space such that the first folding section of the folding board covers a top side of the tube and the second folding section is fit into and interposed between the tube and the rear board to have the second folding section simultaneously clamped by and between the tube and the rear board with two opposite edges of the first folding section abutting the tube.

I claim: 
     
         1 . A tube packaging box, which is generally in the form of a box having an open top, comprising a front board, a rear board, a bottom board, and the two side boards such that the boards collectively form a receiving space, wherein the front board comprises a folding board connected thereto, the folding board being extended to form at least a first folding section and a second folding section connected to an end of the first folding section. 
     
     
         2 . The tube packaging box according to  claim 1 , wherein the first folding section of the folding board and the front board defines a foldable connection therebetween. 
     
     
         3 . The tube packaging box according to  claim 1 , wherein the first folding section of the folding board has a length substantially corresponding to a width of a space between the front board and the rear board. 
     
     
         4 . The tube packaging box according to  claim 1 , wherein the first folding section of the folding board starts from a portion of the front board that is lower, in position, than upper ends of the two side boards. 
     
     
         5 . The tube packaging box according to  claim 1 , wherein the second folding section of the folding board defines a foldable connection with respect to the first folding section. 
     
     
         6 . The tube packaging box according to  claim 1 , wherein the second folding section of the folding board has a length that is not greater than a height between the connection of the first folding section with the front board and the bottom board. 
     
     
         7 . The tube packaging box according to  claim 1 , wherein the second folding section of the folding board has a width that is greater than a width of the first folding section. 
     
     
         8 . The tube packaging box according to  claim 1 , wherein the rear board comprises a portion extending from connections thereof with the two side boards to form a circular arc contour such that the rear board has a height greater than a height of the two side boards. 
     
     
         9 . The tube packaging box according to  claim 1 , wherein the rear board comprises a hollowed section formed therein. 
     
     
         10 . The tube packaging box according to  claim 9 , wherein the hollowed section has an upper part that comprises a circular arc.
