Description

A height-adjustable postal carton

technical field

The utility model relates to a postal carton, in particular to a height-adjustable postal carton. the

Background technique

When we go to the post office to mail items, we need to use the standard carton provided by the post office. The carton is a common hexahedron structure, which is formed by a piece of cardboard. The joints are nailed or glued. The upper and lower flaps of the box can be used to close the carton. The carton is in a flat shape during transportation. When in use, first fold the lower flap flat and then seal it firmly with adhesive tape, then put the postal items in the carton, and then seal the upper flap. However, there are many kinds of mailing items, and their shapes and sizes vary greatly. However, the standard specifications of postal cartons that the post office can provide are relatively limited. Choose a carton with a larger size, and then put some waste newspapers or shredded paper strips between the carton and the mailed items, which can play a buffering and protective role, so as to avoid the mailed items being shaken and damaged during transportation. But such operation has increased the mailing cost of the mailer, and has also affected the aesthetics of the interior of the mailed article. Mailers complain that the post office cannot provide more cartons to choose from, but from the perspective of the post office, it needs more funds to make postal cartons of different sizes suitable for various mailing items for the mailer to choose. storage space, which is also unrealistic. the

Utility model content

Aiming at the problem that the height of the existing postal cartons is fixed and cannot meet the diverse needs of consumers, the utility model provides a height-adjustable postal carton with a simple structure and easy industrial production. the

The utility model is achieved through the following technical measures. A height-adjustable postal carton, including a box body and corner guards. The box body is composed of a body panel, a tongue, a top outer flap, a top inner flap, a bottom outer flap, and a bottom inner flap. The body There are several horizontal indentation lines, inclined indentation lines at an angle of 45 degrees to the horizontal indentation line, and inclined indentation lines at an angle of 135 degrees to the horizontal indentation line in the middle of the plate and the tongue. The carton can be folded and stretched in the height direction; the corner is L-shaped at right angles, and the lengths of the two sides of the corner can be the same or different, and the length of the corner is the same as that obtained by folding or stretching the carton in the height direction. of the same final size. the

The production process of the height-adjustable postal carton involved in the utility model is the same as that of the existing common hexahedral carton, and can be completed on the existing common hexahedral carton production line.
