First, the design principle
1. Make the designed packaging products show good containment, protection and convenience, and have the advantages of beauty and economy.
2. Satisfy the consumer's habit of first observing the main decorative surface of the carton pack when deciding to purchase, the main decorative surface of the carton pack should be designed on the front panel of the carton, with explanatory text and secondary graphic designs on the end plate and rear Board.
3, to meet the consumer in the observation and removal of the contents from the front to the back of the habit of opening, the overall pattern with the cover as the top, the bottom as the bottom, open the top position.
4. Satisfy the consumer's habit of right-handed opening of the lid. The overall pattern is with the left end as the top and the right end as the bottom, but the open position is at the right end.
Second, the size of the lid and the size calculation of the box
1, the size of the box:
According to the packaged goods, which are heavy and easily damaged, in order to improve the strength and rigidity of the carton, the stiffness of the four walls of the carton is strengthened, and a "double L" type carton is used.
It is known that the product size is respectively Φ=55mm, ie: L=55mm, B=55mm, H=121mm. Internal dimensions k': LB - (3-5) mm, H - (1-3) mm; Manufacturing dimensions k: LB - 2mm, H - 1mm; External dimensions: k, take t - cardboard thickness 1mm.
The internal dimensions of the box:
Xi=Xmax nx+d(nx-1)+k'
Bi = 55 + 4 = 59mm
Li = 55 4 + 1 (4-1) + 4 = 227 mm
Hi =121 1+1(1-1)+2=123mm
Box manufacturing dimensions:
X=Xi+t+k
B1=Bi+t+k=59+1+2=62mm
B2= Bi+3t+k=59+3 1+2=64mm
L1= Li+t+k=227+1+2=230mm
L2=Li+3t+k=227+3 5+2=232mm
H= Hi+t+1/2t+k=123+1+1/2+1=125.5mm
The external dimensions of the box:
X. =Xi+t+k(k=t)
B. =Li+t+k=230+3+1=234mm
L. =Bi+t+k=62+3+1=66mm
H. = Hi+t+k=125.5+1/2+1=127mm
2, the lid size calculation:
The internal dimensions of the lid:
X'=X. +(m-1)t+k'
B'=L. +(m-1)+k'=234+(2-1) 1+1=236mm
L'=B. +(m-1)+k'=62+(2-1) 1+1=68mm
H'=H. +(m-1)+k'=127+(2-1) 1+1=129mm
External dimensions of the lid:
X. '=X'+t+ k' m--The number of cardboard layers in the lid is 2 k'--correction factor (k'=t=1)
B. '=L'+t+k'=236+1+1=238mm
L. '=B'+t+k'=68+1+1=70mm
H. '=H'+t+k'=129+1+1=131mm
Third, the flat development of the box, box cover
Press the solid line of the plane unfolding to die-cut, press the dashed line to indent, and press the solid line to reverse the indentation. (to be continued)
