Folding member and folding package Technical field

The technical field of folding packaging of the present invention relates to a folding member, which is a folding structure in a folded package, so that the folded package can quickly transition from a flat state before folding to a closed or semi-closed after folding. The present invention also provides a folded package, such as a folding box or a folding box, and the like.

Background technique

The outer packaging of express delivery mainly includes paper bags, plastic bags and cartons (boxes). Among them, the environmental protection index of the carton is relatively high, and it is already in large use. The raw material of the carton is generally a piece of cut cardboard. For different items to be packaged, it is necessary to design a variety of cardboard, and make a good folding line, according to the established The folding step is sequentially folded along the fold line and folded to form a corresponding carton.

The carton is most common in a rectangular carton. As shown in Fig. 1, a conventional rectangular carton includes four sides, a top surface 3 and a bottom surface 4. The top surface 3, the bottom surface 4 and the two side surfaces 2 of the rectangular carton are sequentially connected. The other two sides 5 are connected to the bottom surface and need to be connected to the remaining sides by means of snapping and/or bonding.

A common bonding method is to provide the bonding body 1 on the side 2, and after bonding, the bonding body is bonded in the side 5 adjacent thereto, and a rectangular carton has four bonding bodies 1 which the manufacturer needs to The four bonding bodies 1 are sequentially bonded, and the positional deviation of any one of the bonding bodies (expressed as the area where the bonding body is adhered to the side inner wall is different) affects the shape of the entire carton and is time consuming.

Utility model content

As described in the background section, the technical problem to be solved by the present invention lies in the partial cardboard between The bonding cannot be performed at the same time, which is not only time-consuming, but also has a certain difference in the different bonding sites, so that the shape of the formed carton cannot be completely uniform, the strength thereof cannot be guaranteed, and a folding member is provided for the problem.

a connecting edge, a first end point connecting the first access side, a second end point connecting the second access side, and at least one connection point;

At least one longitudinally-folded line connected to the connecting edge by a connecting point;

The longitudinally folded hole is disposed on at least one longitudinal fold line;

The connection point is located between the first end point and the second end point, and when the folding board is folded along the longitudinal line, at least a portion of the first access side and the second access side coincide.

The folding plates in the folding member are respectively connected to the cardboard forming one side of the carton through the connecting edge, the first access side and the second access side, and are folded along at least one longitudinal fold line, the longitudinal fold line and the connection The connecting point of the edge is located at the first end point and the second end point, and after folding, at least part of the first access side and the second access side coincide, thereby completing the construction of three adjacent faces of the paper box, due to the folding member As a standard part, not only can the folding consistency be ensured, the deviation can be basically eliminated, and multiple folding members can be folded at the same time, so that the folding work of the cardboard transformation carton is completed at one time, and the folding efficiency is greatly improved.

In addition, the utility model is provided with longitudinal folding holes on at least one longitudinal folding line, as shown in Fig. 3. After the longitudinal folding line is folded, the thickness of the folding portion is increased by folding, which increases the difficulty of folding, and the longitudinal pair The folded faces 8 on both sides of the fold line 7 are pressed against each other after folding, and a tensile force is applied to the longitudinally folded line 7, which severely causes tearing. As shown in FIG. 4, the longitudinal split hole 9 is disposed on the longitudinal fold line 7 of the present invention. The longitudinal split hole is disposed on the longitudinal fold line, and the position of at least part of the longitudinal fold line is occupied by the longitudinal fold hole.

After the longitudinally folded holes are folded along the longitudinal direction, the thickness of the folded surface is partially reduced, but the range of action is often limited to the vicinity of the longitudinally folded holes. A common situation is that the longitudinally folded holes are mostly distributed on the longitudinal fold line or in the vicinity of the area, and away from the area, the thickness of the folded surface cannot be correspondingly reduced after folding, so that there may be a fold The thickness of the folding member is uneven, and the tensile strength of the folding member after folding is reduced. The folding plate of the present invention further comprises a lateral fold line connecting the first access side and the second access side and a horizontal fold line. Horizontally folded holes. After being folded in the lateral direction, the thickness of the folded folded surface can be increased to enhance the overall strength of the folded member.

The laterally folded holes of the utility model are arranged on the transverse fold line, and not only the lateral pair The case where the fold line is occupied by the laterally folded holes, in fact, also includes the case where the laterally folded holes are disposed on both sides or one side of the lateral fold line.

The folding member of the utility model can be applied to the folding operation in the process of converting various cardboards into a three-dimensional packaging (for example, a cubic carton), and the folding members can be designed differently according to the shape of the packaging and the folding method. Shape, you can also design different longitudinal fold lines, horizontal fold lines, first access edge, second access edge, connection edge and connection point:

Referring to Fig. 6, a pentagon-shaped folding member, in the figure 13, 14, 15 can be used as a connecting edge, a first access edge or a second access edge, and more generally, the first The access edge and the second access edge are respectively located on both sides of the connecting edge; when 14 is used as the connecting edge, 9 and 10 can be used as the longitudinal folding line, and more generally, the longitudinal folding line can be connected. a symmetry line of the folding member of the bottom edge or a fold line (such as 10) disposed in the folding member at an angle of less than 90° with the symmetry line; when 14 is used as the connecting side, 11 and 12 can be used as A transversely-folded line, or a fold line (e.g., 12) disposed within the folded member with an angle of 11 (90° to the line of symmetry) of less than 90°.

In the present invention, the included angle may be formed by the intersection of two straight lines, or may be formed by the intersection of the respective extension lines of the two straight lines.

The folding member of the present invention can be adapted to different folds by imparting different shapes to the folding members and designing different connecting edges, first access sides, second access sides, longitudinal fold lines and transverse fold lines. The technique and the demand, so that the transition from cardboard to three-dimensional packaging becomes very simple and rapid. Those skilled in the art can also appropriately add or remove the lateral fold line and control the number of longitudinal fold lines to ensure the convenience of folding and the strength of the folded package.

A special case is that the connecting edge is a connection point. At this time, the connection of the folding member to the cardboard substantially depends on the first access side and the second access side.

The use of the folding member of the utility model can not only greatly facilitate the conversion of the cardboard to the three-dimensional packaging, but also the folding member can occupy the corner portion of the cardboard. Before the present invention, the corner portion of the cardboard is generally based on Folding needs to be discarded, from the shape of the cardboard to be folded, most of They are not square, so the square cardboard coming out of the paper mill needs to be cut and cut, and the whole square cardboard can not be used well, which causes waste of the cardboard raw materials.
