FIELD OF THE INVENTION 
       [0001]    The present application relates to a tie system to be used in plastic containers or boxes, for storing and transporting all kind of fresh food, such as horticultural produce, meat (beef, fish, port, etc.) or the like. 
       DESCRIPTION OF THE INVENTION 
       [0002]    Normally, plastic boxes or containers are self-supporting, the joint strength and rigidity existing between the side walls and the bottom just sufficing thereto, and which allows only a certain amount of pressure upon said side walls and bottom, its filling capacity being limited to the strength generated by certain volume of product and its specific density that exerts pressure on the side walls, which tends to open and distort the box or container, making difficult their piling up and stability, ad may cause said walls and bottom to break. 
       BRIEF DESCRIPTION OF THE INVENTION 
       [0003]    This specification relates to a system comprising a couple of plastic ties, their ends having holes, each forming a first portion of a clasp, and which runs from a protuberance forming a second portion of a clasp system located close, or at one of the four vertexes of a regular rectangular plastic box, to another protuberance or second portion of a clasp system located close or at the vertex diagonally opposite to said plastic box, said ties increasing the rigidity and stability of the entire box, the box keeping its rectangular shape, causing the side walls and the box or container to distort less. 
         [0004]    In another embodiment of the present application, the fastening of the ties to the box may be made by way of screws, a clip or any other mechanism used to fasten the ties to the box. 
     
    
     
       BRIEF DESCRIPTION OF THE FIGURES 
         [0005]      FIG. 1  shows a whole tie. 
           [0006]      FIG. 2  shows details of the ends of a tie. 
           [0007]      FIG. 3  shows the mechanism through which the tie is fastened to the box or container. 
           [0008]      FIG. 4  shows the whole box or container and the way the ties are installed. 
       
    
    
     DETAILED DESCRIPTION 
       [0009]    The present utility model comprises two plastic ties each comprising a central bar ( 2 ), which, in turn, has two ends ( 3 ) having a hole or a first portion of a clasp ( 4 ) at each one of said ends ( 3 ). These ties are installed by locating them diagonally, joining two diagonally opposite vertexes of the box or container ( 1 ), as shown in  FIG. 4 . A protuberance or second portion of a clap is located at, or close to, one of the vertexes of the box or container, the hole ( 4 ), being located at one of the ends ( 3 ) of the ties being pressure-inserted thereon. The action is then repeated with the other tie by using protuberances or second portions of a clasp in the box being diagonally free.
