Structural Design of Folding Carton

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.
