Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
A kind of schematic diagram of the hanging type packaging of headlight for vehicles of the utility model is as Figure 1-Figure 2.One paper of packing case
Molding, bottom use self-locking bottom structure, and cover board can carry out four sealings by setting tongue, tear strip and adhesive tape and open.Packet
Vanning includes bonding flap 1, foreboard 2, left plate 12, back plate 20 and the right side plate 22 for successively folding connection.The upside of foreboard 2 with
First cover board 4 folds connection, and downside and the first bottom plate 28, which fold, to be connected.The upside of left plate 12 and dust-proof flap 1 fold
Connection, downside and dust-proof flap 2 26, which fold, to be connected.The upside of back plate 20 and the second cover board 29, which fold, to be connected, downside and second
Bottom plate 25 folds connection.The upside of right side plate 22 and dust-proof flap 3 21, which fold, to be connected, and downside and dust-proof flap 4 23 fold and connect
It connects.The first bottom bonding sheet 27 is arranged in the right side of first bottom plate 28, and the second bottom bonding sheet 24 is arranged in the right side of the second bottom plate 25.First
The lower part of the top setting tongue 1 and tongue 29 of cover board 4, tongue 1 and tongue 29 sets gradually tear strip 1, adhesive tape
One 6, tear strip 25.The lower part setting interpolation slit 1 and interpolation slit 2 10 of first cover board 4.Tongue three is arranged in the top of second cover board 29
14 and tongue 4 18, the lower part of tongue 3 14 and tongue 4 18 sets gradually tear strip 3 13, adhesive tape 2 16 and tear strip four
17.The lower part setting interpolation slit 3 15 and interpolation slit 4 19 of second cover board 29.Packaging material is paper material.
When molding, flap 1, foreboard 2, left plate 12, back plate 20 and right side plate 22 successively infolding will be bonded, and the flap will be bonded
A piece of 1 bonds with right side plate 22.By 25 180 degree of upward reflexed of the first bottom plate 28 and the second bottom plate, then by the first bottom bonding sheet 27
With the downward reflexed 180 degree of the second bottom bonding sheet 24, will be bonded after 27 gluing of the first bottom bonding sheet with dust-proof flap 2 26, by the
It is bonded after two bottom bonding sheets, 24 gluing with dust-proof flap 4 23.
When packaging, commodity are packed into packing case, by 3 21 infolding of dust-proof flap 1 and dust-proof flap, by the second cover board 29
Infolding;By 4 infolding of the first cover board, tear strip 1 is pulled open, then tongue 1 and tongue 29 expose, and tongue 1 is inserted into and is inserted
4 19 are stitched, tongue 29 is inserted into interpolation slit 3 15, completes first time joint sealing.Due to the company of tongue one and tongue two and the first cover board
It is fluted to meet place, therefore, tongue cannot then be extracted, otherwise tongue can destroy, and play anti-theft function once being inserted into.It, will when opening
Tear strip 7 is torn, and realizes operation of unpacking for the first time.Second in use, by adhesive tape 1 by the first cover board 4 and the after recycling
The bonding of two cover boards 29.When opening, tear strip 5 is torn, realizes second of operation of unpacking.Third time after recycling is in use, by the
The tear strip 13 of two cover boards 29 pulls open, and tongue 3 14 is inserted into interpolation slit 2 10, and tongue 4 18 is inserted into interpolation slit 1, realizes third
Secondary joint sealing operation.When opening, tear strip 13 is torn, realizes that third time is unpacked and operates.After recycling, the 4th time in use, pass through
Adhesive tape 2 16 bonds the second cover board 29 and the first cover board 4, and when opening, tear strip 17 is torn, and realizes the 4th operation of unpacking.
The packaging material is paper material.
Four circulation express delivery Packaging Box of the utility model are four times recyclable, are used for multiple times, save paper material, are conducive to
Environmental protection;Using self-locking bottom structure, carton intensity is high;Unique tongue design, plays anti-theft function.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
