Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail, but the utility model
It is not limited to these embodiments.
The present embodiment express delivery box is suitable for placing three strip products, expansion floor map such as Fig. 2 institute of the express delivery box
Show, only can be fabricated to the express delivery box by cutting to fold with a piece of cardboard, layout is only needed using simple flat raft, and cutting is useless
Material is few, greatly improves the utilization rate of raw material cardboard, has saved raw material.
The size relationship of each component of the utility model express delivery box is as shown in figure 3, first determine the length of the built-in product of express delivery box
L, width b and height h (see Fig. 4), then determine the size of remaining part;In Fig. 3, Δ d represents the separation of card slot 9, and b ' is represented
The groove width of card slot 9, d represent the groove depth of card slot 9, d1It represents distance of the card slot bottom away from carton edge, t on length direction and represents paper
Plate thickness, n represent the cardboard number of plies.The following are dress, there are three each dimensional parameters of express delivery box box base of strip product:
(1) top plate: long L1=L+2 × d1+ t, wherein d1Usually take 2.5~3cm;Wide B1+ 4 Δ d+t of=3b ', wherein b '=
b;
(2) top-side panel: high H2=h/2+t;Wide B2+ 4 Δ d of=3b ';
(3) back plate: long L3=L1+(n-1)t;High H3=h+t;
(4) bottom plate: long L4=L1+(n-1)t;Wide B4=B1+t;
(5) backplate: wide B is folded5=B1;High H5=H3;The wide B of inner panel5'=H3;
(6) foreboard: long L6=L3;High H6=h+t/2;
(7) sealing plate: L7=L1+(n-1)t;High H7=H6;
(8) folded side plate: B8=H5+B5'+6t+3t;H8=h;
(9) groove depth d can be determined according to content length, it is generally the case that d takes 3cm, the groove depth when content length is larger
It is appropriate to increase, on the contrary reduce.
The length L of the built-in product of embodiment express delivery box takes 100cm, width b that 8cm, height h is taken to take 30cm, the slot of card slot 9
Separation delta d takes 6.5cm, and groove width b ' is identical as b, and 8cm, groove depth d is taken to take 8cm, distance d of the card slot bottom away from carton edge1It takes
3cm, it is the corrugated paper of 0.3cm that cardboard, which selects thickness t,.Top plate length L1=100+2 × 3+0.3=106.3cm, width B1=3 ×
8+4 × 6.5+0.3=50.3cm;Top-side panel height H2=30/2+0.3=15.3cm, width B2=3 × 8+4 × 6.5=50;Afterwards
Plate length L3=106.3+ (6-1) 0.3=107.8cm, height H3=30+0.3=30.3cm;Floor length L4=106.3+
(12-1) 0.3=109.6cm, width B4=50.3+0.3=50.6cm;Fold backplate width B5=50.3cm, high H5=
30.3cm;The wide B of inner panel5'=30.3;Foreboard length L6=106.3cm, height H6=30+0.3/2=30.15cm;Sealing plate length
L7=106.3+ (10-1) 0.3=109cm, height H7=30.15cm;Folded side plate width B8=30.3+30.3+6 × 0.3+3
× 0.3=63.3cm, height H8=30cm.
The assembling of the utility model express delivery box use process is as follows:
Referring to Fig. 2, first strip product is fixed in left and right card slot 9, by side plate a3 to turning on the basis of cover board 2
Folding, side plate b5 is flipped up on the basis of cassette bottom 4, by the side plate c6 of express delivery box two sides and stiffening plate 7 along indentation line infolding, to box
Then otic placode a8 is become bilayer along intermediate crease line infolding, then the double-deck otic placode a8 is inserted into side plate c6 by interior 90 ° of fold
In the gap of stiffening plate 7, the double-deck otic placode b10 is inserted between side plate c6 and otic placode a8, closes express delivery box, finally in side plate
The sealing part of d12 pastes two-dimension code label.
Referring to Fig.1, the present embodiment express delivery box structure after molding includes the hollow box 1 of upper end opening, box body 1 opposite two
L-shaped reinforcing plate a7 (see Fig. 5), stiffening plate a7 and the side plate c6 turned down to the inside of box body 1 is connected separately at the top of a side plate c6
Cuboid buffer structure is formed, the compression strength of express delivery box is enhanced.The both ends of box body 1 other two opposite side plate b5 and side plate a3
It is respectively connected with the double-deck tongue a8, tongue a8 is less than the width of side plate far from the width on side plate one side, convenient for the insertion of tongue.Tongue
For a8 between side plate c6 and stiffening plate a7, the double-deck tongue can preferably fill the gap between side plate c6 and stiffening plate a7, increase
The compactness of strong express delivery box.
It is covered on the open-topped cover board 2 of box body 1 after being connected with fold at the top of side plate a3, cover board 2 connects respectively with respect to both sides
Be connected to the L-shaped reinforcing plate b11 (see Fig. 6) turned down to the inside of box body 1, stiffening plate b11 it is opposite with cover board 2 be provided with rectangle on one side
Card slot 9, the width of card slot 13, which is subject to, can block product in box, and the opposite card slot 13 in 2 both sides of cover board can fix product in box,
It avoids generating impact failure in box between product.
2 another side of cover board is connected with the side plate d12 being affixed after fold with side plate b5, and the both ends side plate d12 are connected separately with double
Layer tongue b10, tongue b10 are less than the width of side plate d12 far from the width on the one side side plate d12, are inserted into cassette interior convenient for tongue;
Between side plate c6 and tongue a8, cover board 2 and box body 1 are closely joined together tongue b10 by tongue b10, make express delivery box not
With the box that can become a sealing by adhesive tape.Two-dimension code label is designed on side plate d12, convenient for courier to box-packed production
The classification of product also facilitates consumer query product information.
It is more tight, enhance its safety.The two-dimension code label of 1 sealing part of sealing plate is except link consumer and product stream communication
Breath is outer, also acts as sealing function, bonds without adhesive tape, economic and environment-friendly.In addition, the layout of this cell type is only needed using simple flat
Row, cutting waste material is few, greatly improves the utilization rate of raw material cardboard, has saved raw material.
The above is only a kind of specific structures without adhesive tape tongue formula environment-friendly type express delivery box of the utility model, but this is practical
It is novel to be not limited to above-mentioned specific embodiment.
