Section 3 disc folding cartons

A disc folding carton

1, disc folding cartons

According to the forming characteristics, the tray folding carton is folded into a main box type at a right angle or an oblique angle around a sheet of cardboard, and sometimes it is locked or glued at corners. There are almost no structural changes on the bottom of the box, and the main structural changes In the box position.
Suitable for packaging footwear, clothing, food and gifts.

2. Rotational Forming of Disc Folding Cartons Each box panel adjacent to a corner is rotated around a point, which is the vertex of the plane of the bottom of the box.
A molding angle: the angle formed by the adjacent two sides of the bottom of the disc folding carton is
A molding angle, denoted by α.
B. Forming angle: The angle formed by the line of intersection of the body plate of the disc folding carton box and the bottom line of the box is the B forming angle, which is represented by 1γ, 2γ...
Rotation angle: In the plane unfolding view of the disc folding carton, the angle formed by the adjacent two body plates (the side plate and the end plate) is the rotation angle, denoted by β.
The tray type corrugated carton is mainly used for fruit and vegetable packaging. Its characteristic is that the upper and lower layers are interlocked when stacking and thus have good stability.

Second, the formation of disc folding cartons

2, the lock 1 lock mode 2 lock structure
3, adhesive type simple box corner

Third, the lid structure of the disc folding carton

1. Cover-type cover The cover of the box is two independent disk-type structures. The length and width of the cover are slightly larger than the box.
1 day cover type: HH + ≥
2 Cap style: HH + <
3 pairs of cover styles: 1H HH + = + (where 1
H is the full height of the carton)
2, shake type
3, insert type
4, are sealed
5, drawer cover
6, lock type

Four, disc folding carton bisecting angle design

1. Adhesive or non-adhesive simple box corners are processed at the corners of the disc cartridge.
2, the direction of the transformation of a certain part of the folding cartons through the bisector of the bisector, to achieve the direction of the structure of the part of the transformation.
3, the tray type automatic folding carton can be folded into a flat shape after use, as long as the use of open box, the carton automatically restore the shape.
1Beers type folding cartons are divided into two types: inner folding and outer folding. Whether it is meat folding or folding, the folding line divides the B forming angle equally.
2 Brightwoods Folding Carton 3 Forward Folding Carton Folding both inward and outward, if the angles α, 1 γ, 2 γ are all 90°, then the fold line and the bottom of the box The angle is 45°, ie, the angle is the bisection angle of the B forming angle 1 γ.
4TLIC. The third formula - the formula for solving the internal folding angle 5 TLIC The fourth formula - the formula for solving the external folding angle 5. Stacked paper box

Section IV Tube Folding Carton

First, the tube tray folding cartons

The traditional profiled box, whether tubular or disk, is at any point of rotation at its corner.
The so-called tray-type folding carton is a feature of the box type, and a partial box of the disc cartridge is formed by the rotational molding method of the tube box.
If the box shape of some A forming angle is greater than 180 °, you can consider designing a tube type.
It can be designed by using the characteristics of the tube box rotation molding.
2. A forming outside corner
A molding outside corner is the outside corner of the box bottom or box after the carton is formed, denoted by α′.
It can be designed by using the characteristics of the tube box rotation molding.

Second, tube tray automatic folding cartons

2. TLIC Formula 5 - Formula for solving the folding angle of tube-folding cartons

Section 5 non-tube non-disc folding carton structure

First, the molding characteristics of non-tube non-disc folding carton

Non-tube non-disc folding cartons are usually partitioned multi-packs.
a. The main structure of the carton has a number of structural points, and the intersection of any group of structures passing through these points includes both the cut line, the inner fold line, and the outer fold line (or the double fold line).
b. The main structure of the carton is along a certain cutting line and the left and right ends of the cardboard are relatively horizontally moved by a certain distance, and overlap each other at a certain position.

Second, reverse fixed structure

1. Reverse-twisted fixed structure The reverse-twist fixed structure uses the foldability of cardboard and the strength and stiffness of the paperboard itself. Fixed things.
2. Multi-beverage beverage collection box with back wall type 1 Multi-piece beverage folding box 2 multi-piece beverage collection box

Third, non-tube non-disc folding carton structure

The main structure is completely formed according to the molding method of non-tube non-disc folding carton.
The molding process is:

Section VI Functional Structure of Folding Carton

A special-shaped profiled folding carton refers to a box type other than a right-angled hexahedron. It can be formed either by basic molding methods or by special design techniques based on the basic structure.
1、The upper or lower part of the paper box is changed by slash indentation
2, the carton box body changes through slash indentation
3, box shaped gradient shaped box
4, the lid is shaped arch shaped box
5, other local changes in the special-shaped box II, partition wall type folding cartons in addition to the partition wall type, there is a partition wall format, it does not use the floor to double as a liner,
Instead, spacers are designed using the extensions of the upper or side panels.
Third, the combination

A combination box means that two or more equal basic boxes are formed on a sheet of paperboard, and they can still be connected to each other after molding, and a large box is formed as a whole.
Fourth, more than one set of five, to mention the setting of hand-held mainly based on the weight and shape of the contents to determine the appropriate handle material or structure.
6. The structure of windows and windows can partially display commodities, and it has the function of promoting sales.
Seven, show
1, the characteristics of display tray
2, the basic structure of the display tray 8, easy to open structure
1, easy to open the carton design points
2, open the structure of the position on the tray
3, the basic form of opening
4, combined open form nine, inverted outlet structure inverted outlet generally use a point as the axis of the rotary sliding, there are also selected to open, close, pull and other operating methods to open or close the inverted outlet.
