Fourth, the box body, lid folding forming
The dotted line in the plane development view is folded inwards, and folded outwards according to the actual solid line, formed into a box body and a box cover as shown in the figure, and bonded at the folded end surface, that is, formed by a box corner bonding method.
Fifth, the lid design
On the lid, the trade name, trademark, article number, package quantity, production plant, production date, shelf life, bar code, etc. are printed, and the art is decorated so that the package box attracts people's attention.
Second, corrugated box structure design
First, the design principle
Second, the size of corrugated carton
Q-type arrangement: L//b, B//l, H//h. 1 238:5 70:2 131, in line with the best box type ratio.
nL nB nH=L 5B 2h.
Each bottle weighs about 300 grams and the total weight is 300 30 = 9 kg. Check from the table tBC = 7.1mm, namely k values ​​L1-8, L2-5, B1-8, B2-5, H-14.
Corrugated carton internal dimensions:
Xi=Xmax nx+d(nx-1)+k'+Tk' Small box takes 1-3mm, takes k'=3mm; T=0; d takes 1-2mm, takes d=2mm
Bi = 238 + 2(1-1) + 3 = 241mm
Li = 5 70+2(5-1)+3=361mm
Hi = 2 131+2(2-1)+3=267mm
Corrugated box manufacturing dimensions:
X=Xi+k
B1=Bi+k=241+8=249mm
B2= Bi+k=241+5=246mm
L1= Li+k=361++8=369mm
L2= Li+k=361+5=366mm
H= Hi+k=267+14=281mm
Corrugated carton external dimensions:
X. =Xi+2tBC
B. =Li+2tBC=241+2 7.1=255.2mm
L. =Bi+2tBC=361+2 7.1=375.2mm
H. = Hi+2tBC=267+2 7.1=281.2mm
Corrugated box flap size:
F=1/2Bi+X+(k) k takes k=3
F=1/2 241+3=123.5mm
Corrugated box connector size:
Because the material is a double tile BC type corrugated board, so take J = 40mm
Third, the corrugated box of the ring pressure strength calculation
The use of BC corrugated board, cardboard grade: 240/240-151/1C; cardboard ring pressure strength: P1 = 320N/15.2cm, P2 = 320N/15.2cm, Pm = 180N/15.2cm, Pm1 = 180N/15.2 Cm.
Double-corrugated cardboard's formula for calculating the composite ring pressure:
Press the solid line of the plane expansion to die-cut, and press the dotted line to indent.
8. Folding and Forming of Corrugated Boxes After the press marks are folded and formed, the two splices of the anti-carton of the staple-bonding method are stapled together to form a carton as shown in the figure.
Nine, corrugated carton design
The exterior of the corrugated carton is decorated and printed with:
1 Identification marks, such as: commodity name and trademark, product number and quantity mark, production plant, etc.;
2 signs, such as: be careful, gently, up, etc.;
3 barcodes.
