Abstract

The utility model discloses a folding type packing box structure. The folding type packing box structure is characterized in that a semi-open type, a full-open type and a full-closed type box body structures can be formed by folding marks; two sets of folding marks in pair are arranged on two corresponding side walls of the box body; each set of folding marks in pair comprises the folding mark perpendicular to the bottom edge and a folding mark forming a 45-degree included angle with the bottom edge; the directions of the folding lines of the folding marks are in opposite; the folding structure can be formed by the folding mark so as to satisfy the full-open, semi-open and full-closed requirements of the box body. A cover box can be folded by the folding type packing box structure, so that the folding type packing box structure is convenient to carry, is practicable as a lunch box, is convenient to transport and also can be totally opened; moreover, the area of the folding type packing box structure is fundamentally doubled, and the folding type packing box structure is used as a dinner plate.

Description

A folding packaging box structure

technical field

The utility model relates to a box body structure, in particular to a foldable integrated lunch box. the

Background technique

In view of the fact that the meal boxes used by mainstream airlines cannot be fully opened when serving food, there is insufficient space for food placement. It is easy to cause food to spill when encountering airflow. For this reason, this box is specially designed, which can be closed as a lunch box or fully opened as a dinner plate. This product is also suitable for other transportation and catering industries. the

Utility model content

The purpose of this utility model is to propose a folding packaging box structure, so that it has the concept of environmental protection, and uses the most economical piece of paper or other materials with certain strength and foldability, including materials such as cardboard, plastic or cork. , as long as it is folded according to the folding line, a closed box structure can be formed. the

In order to achieve the above object, the technical solution adopted by the utility model is:

A foldable lunch box, which is special in that the creases can be used to form a semi-open, fully open and fully enclosed box structure, and two sets of paired creases are provided on the two side walls corresponding to the box body. Each set of paired creases includes a crease perpendicular to the bottom edge and a 45-degree angle to the bottom edge. The direction of the crease lines is opposite, as follows:

Firstly, an open box structure is formed by two folds parallel to the upper and lower bottom edges and equidistant a from the upper and lower bottom edges, and another two creases parallel to the left and right bottom edges and equidistant a distance from the left and right bottom edges to form an open box structure. The height of the body (as shown in Figure 4), and then two pairs of creases are located on both sides of the middle of the box body raw material, which is symmetrical up and down with the box body raw material transverse symmetry axis, and the two creases perpendicular to the side of the box body are based on the box body raw material The longitudinal axis of symmetry is symmetrical to the left and right, and the distance between them is equal to the height of the final box body. In addition, the two creases forming an angle of 45 degrees with the side of the box body intersect with the aforementioned creases on the upper and lower bottom edges of the box body. Each composition is folded in half. The two fold lines of the trace are in opposite directions. the

The directions of the crease lines parallel to each other in two pairs of crease groups can be the same or different. For the convenience of large-scale industrial application, it is optimal for the crease lines parallel to each other between the groups to be in the same direction and up and down. symmetry. the

The folding structure can be formed by the above creases to meet the full opening, semi-opening and full closing of the box body. the

It can be folded into a box with a cover, which is easy to carry, practical as a lunch box, and convenient for transportation, and can also be fully opened, so that its area basically doubles, and can be used as a dinner plate. the

Description of drawings

Fig. 1 is the plan view of the original crease of the box body structure of the present utility model. the

Fig. 2 is a side view of the utility model folded into a semi-open box structure. the

Fig. 3 is a perspective view of a fully enclosed box of the present invention. the

Fig. 4 is a side view of the utility model unfolded into a fully open box structure. the

Among them, the dotted line represents the inner polyline. a, the height of the formed box; b, the length of the formed box; c, the width of the formed box. 1-1, 1-2, 2-1, 2-2 are creases respectively. the

Detailed ways

The folding lunch box is made of hard paper; 5 cm inward creases are left on the hard cardboard with a length of 45 cm and a width of 34 cm. Subtract an isosceles right triangle from the four corners respectively. Use the 5cm beyond this crease as a side. See Figure 1. Fold in half in the center, and make 2.5cm creases symmetrically on both sides of the central crease, with the creases facing inward. Make two outward 45 degree diagonal creases on the same side. The first crease is the line connecting the long side and the intersection point of the two central creases. The second crease is parallel to the one next to it, starting at the left intersection. The same is done on the opposite side, and they are parallel to the opposite side. See Figure 2 and Figure 3 for details. Turn up the creases on the side and rivet the triangular protrusions to the adjacent side with staples as the height. the

The foldable lunch box can save space when closed, and food and articles can be placed there. Gently pull the lid, you can live and unfold, expand the use area. the

Claims (2)

1. A folding packaging box structure, which is special in that the box body material can form a semi-open, fully open and fully closed box structure by using creases, and the two side walls corresponding to the box body There are two sets of paired creases on the top, and each set of paired creases includes a crease perpendicular to the bottom edge and a crease at an angle of 45 degrees to the bottom edge. The directions of the fold lines are opposite, as follows: Firstly, an open box structure is formed by two folds parallel to the upper and lower bottom edges and equidistant a from the upper and lower bottom edges, and another two creases parallel to the left and right bottom edges and equidistant a distance from the left and right bottom edges to form an open box structure. body height; Then there are two sets of paired creases located on both sides of the middle part of the box body raw material, which are symmetrical up and down with the horizontal symmetry axis of the box body raw material, and the two creases perpendicular to the side of the box body are left and right symmetrical with the longitudinal symmetry axis of the box body raw material It is equal to the height of the final box body, and the two creases forming an angle of 45 degrees with the side of the box body intersect with the aforementioned creases on the upper and lower bottom edges of the box body, and the directions of the two fold lines of each pair of creases are opposite; The folding structure can be formed by the above creases to meet the full opening, semi-opening and full closing of the box body. 2. A foldable packaging box structure according to claim 1, characterized in that the creases parallel to each other between the groups have the same crease line direction and are symmetrical up and down. the
