A kind of folding package box
Technical field
The utility model relates to a kind of folding package box.
Background technology
Usually folding package box is cuboid, has included only six faces, so the face area of the picture and text that can be used for record product explanation or increase attractive packages of packing box is very limited.Because this packing box bottom can not be observed easily usually and be obtained, and just seems still less so be used for the face area of the advertising or the description of product on the packing box.For example at disclosed Chinese patent on November 8th, 2006, notification number is to disclose a kind of folding package box among the CN2835101Y.It comprises the box body that is made of a plane folding cardboard, four limits of the rectangular base plate of box body link to each other with side plate respectively, link to each other with flap respectively with the corresponding sides of base plate bonded assembly side plate, link to each other with cover plate respectively with the corresponding sides of base plate bonded assembly side plate, two limits in addition of side plate link to each other with fin respectively, and the flap end portion side is provided with arc gap groove, and the junction between described each parts is equipped with folding line, cover plate is provided with socket, and another cover plate is provided with the tongue that matches with socket.It is square, cuboid to make the back.Use this packing box can only use the surface of six faces as the advertising or the description of product at most, and put goods on the market at product and to be placed in that the bottom surface of this packing box is blocked on the shelf, therefore using the face normal conditions to guarantee is five.
The utility model content
At the above-mentioned problems in the prior art, the utility model purpose is to provide a kind of technical scheme of folding package box.
Described a kind of folding package box, comprise base plate, with base plate bonded assembly front side plate and rear quarter panel, described rear quarter panel is provided with cover plate, described cover plate shape size is identical with base plate shape size, described cover plate is provided with tongue, it is characterized in that described front side plate is provided with expansion board, is provided with the socket of corresponding tongue between described expansion board and the front side plate.
Described folding package box is characterized in that described expansion board edge is positioned on the described cover plate.
Described folding package box is characterized in that described expansion board area of conter is at most the area of described cover plate.
Described folding package box is characterized in that described expansion board is tabular.
Described folding package box is characterized in that described expansion board is curved.
The utility model adopts technique scheme: increase the face area of packing box by increasing expansion board, make more products explanation of packing box surface energy record and advertising message, thereby remedy the deficiency that the packing box bottom can not be used to show; This packing box forms by complete flaky material is folding, and is therefore simple in structure.Expansion board is positioned at the packing box top, whole packing box face area minimum when expansion board is positioned at the packing box top, the face area maximum of whole packing box when expansion board is erect or spread out, so this packing box has the function of face area adjustable size, flexible and convenient to use.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, and provide the specific embodiment.
A kind of embodiment of the present utility model, as shown in Figure 1, this folding package box is formed behind folding line by a complete carboard, and it has comprised base plate 1, cover plate 11, front side plate 2, rear quarter panel 3, left side board 4, right side board 5, expansion board 6, side plate fin 7, cover plate 11 fins 8 and tongue 9.Base plate 1 is an oblong, and front side plate 2, rear quarter panel 3, left side board 4, right side board 5 are connected around the base plate 1.Front side plate 2, rear quarter panel 3, left side board 4, right side board 5 also are rectangle, and are provided with side plate fin 7 at the two ends of left side board 4 symmetries, also are provided with side plate fin 7 at the two ends of right side board 5 symmetries.Front side plate 2 is connected with expansion board 6, and is provided with the socket 10 of corresponding tongue 9 between front side plate 2 and expansion board 6.Rear quarter panel 3 is connected with cover plate 11, is connected with cover plate 11 fins 8 on the both sides of cover plate 11 symmetries, and tongue 9 is connected the opposite side of cover plate 11.Cover plate 11 is all identical with base plate 1 with expansion board 6 profile sizes, and expansion board 6 is tabular.As shown in Figure 2, back expansion board 6 is installed is positioned at cover plate 11 tops, expansion board 6 edges and cover plate 11 edges maintain an equal level.There has been expansion board 6 just can increase the face area of packing box, has been very beneficial on packing box, increasing more products explanation or advertising message, more perfect exhibiting product function like this by two surfaces of expansion board 6.Expansion board 6 front side plate 2 swing relatively, and remain on a kind of state of spreading out under the effect of self elastic force so just can make the inside face that is positioned at expansion board 6 and cover plate 11 lip-deep pictures or Word message display together; And after expansion board 6 is combined on the cover plate 11, have only picture or Word message on expansion board 6 outside faces to display.Opening and closing by expansion board 6 can also be adjusted the packing box face area, make packing box that better advertising results be arranged under varying environment.
Another kind of embodiment of the present utility model be that with the difference of first kind of embodiment the expansion board 6 of this folding package box is curved, but the area that is projected on the cover plate 11 is identical with cover plate 11 after it is combined on the cover plate 11, and the edge aligns with cover plate 11 also.Because the face area of arcuate structure is greater than the face area of planar structure, so the face area of the relative first kind of enforcement of face area of folding package box among this embodiment wants big.So just can reach the effective surface area that under the prerequisite that does not influence the packing box outward appearance, increases packing box, for businessman brings more facilities and material benefit at the more literal of packing box surface bears, pictorial information.
