Abstract

The utility model relates to a folding packing box, which comprises an outer shell and an inner shell, wherein the outer shell comprises a soleplate, a middle plate and a cover plate; the soleplate, the middle plate and the cover plate can turn and fold; the inner shell comprises a foldable parallelogram frame body and a bottom surface plate which is connected with the frame body. The utility model is characterized in that the bottom surface plate is provided with a cutting gap, and both ends of the cutting gap begin and end in a group of opposite angles of the parallelogram frame body and cut the bottom surface plate into two parts; each part of the bottom surface plate is provided with a section of crease, and two sections of creases are respectively overlapped with the other group of the opposite angles of the parallelogram frame body; the cutting gap and the creases divide the bottom surface plate into four plates, wherein one plate is glued with the soleplate. Since the packing box of the utility model can be folded into a plane plate shape after manufacture, size is reduced, cost of storage and transportation is saved, and production cost is reduced.

Description

A kind of folding packing box

Technical field

The utility model relates to a kind of packing box, specifically, relates to a kind of folding packing box.

Background technology

A kind of well received packing box is arranged at present, it is a kind of duricrust carton, this duricrust carton mainly is made of a hard shell and a hard inner casing, wherein, shell comprises base plate, middle plate and cover plate three parts, after cutting into suitable specification with solid fiberboard during making, attach combination with pliable and tough table paper again, base plate, middle plate and cover plate three parts can be turned down; Inner casing comprises rectangle framework and bottom panel, cut into suitable specification with solid fiberboard during making after, be bonded into a rectangle framework with pliable and tough table paper again, it is container-like to cooperate bottom panel to constitute again; Again that the base plate of the bottom panel of inner casing and shell is bonding, promptly form the packing carton of a solid form.After the cover plate of this packing carton opens, can ccontaining therein article, can also cooperate ribbon or other fastening structure that cover plate is fixed when the closure simultaneously.

This packing box is usually used in the external packing of food (as moon cake, tealeaves etc.), cosmetics, stationery decorative fitting, and packing box obtains beautiful outward appearance by methods such as printings, can improve the class of connection with wrapping of piece.But promptly form the volume of a fixed size after packing box completes,, all must occupy onesize space, therefore in the storage and transportation of packing box, cause the waste in space, increase storage and traffic cost no matter wherein whether put article.

Summary of the invention

The purpose of this utility model provides a kind of folding packing box, and this packing box can be folded into tabular so that storage and transportation are deployable again to be used for packing during use.The technical scheme that adopts is as follows:

A kind of folding packing box, comprise shell and inner casing, wherein shell comprises base plate, middle plate and cover plate, base plate, middle plate and cover plate three parts can turn down, inner casing comprises folding parallelogram framework and coupled bottom panel, it is characterized in that: the one group of diagonal angle that has a joint-cutting, the two ends of joint-cutting to rise on the described bottom panel to terminate in the parallelogram framework also cuts into two parts with bottom panel; One section folding line is arranged on every part bottom panel, and two sections folding lines overlap with another angular bisector of organizing the diagonal angle of parallelogram framework respectively; Described joint-cutting and folding line are separated into four plates with bottom panel, and wherein a plate and base plate are bonding.

For making the packing box that launches after the moulding more firm, can in inner casing, place a shape and the big or small carboard that all is complementary with framework, also can on the cooresponding base plate of other plate of bottom panel, Double-face gummed paper be set.

Described parallelogram framework is modal to be rectangle framework or prismatic framework.

Described joint-cutting can be arbitrary shape, is preferably level and smooth line, is preferably straight line (being the diagonal line of parallelogram framework).

The packing box that the utility model provides can be folded into tabular after completing, reduce volume, to save storage and cost of transportation, cost-cutting; With inner casing expansion and fixing, promptly constitute the packing box of a moulding during use, can ccontaining article.

Description of drawings

Fig. 1 is the structural representation of the utility model one preferred embodiment when being in deployed condition (being the packing box of moulding);

Fig. 2 is the scheme drawing that packing box shown in Figure 1 is in semi-collapsed condition;

Fig. 3 is the scheme drawing that packing box shown in Figure 1 is in folded state (promptly being folded into tabular).

The specific embodiment

As shown in Figure 1, this folding packing box comprises shell and inner casing, wherein shell comprises base plate 1, middle plate 2 and cover plate 3, and base plate 1, middle plate 2 and cover plate 3 three parts can turn down, and inner casing comprises folding rectangle framework 4 and the bottom panel 5 that links to each other with rectangle framework 4.One joint-cutting 6 is arranged on the bottom panel 5, and the two ends of joint-cutting 6 are worked one group of diagonal angle terminating in rectangle frame body 4 and bottom panel 5 are cut into two parts; There are 7, two sections folding lines 7 of one section folding line to overlap with another angular bisector of organizing the diagonal angle of rectangle framework 4 respectively on every part bottom panel; Joint-cutting 6 is separated into four

plates

51,52,53,54 with folding line 7 with bottom panel 5, and wherein a plate 51 is bonding with base plate 1.

As shown in Figures 2 and 3, when packing box completes, promptly can be folded into tabular, when folding rectangle framework 4 is swung to a side, one group of adjacent side and another group adjacent side of rectangle framework 4 are fitted, meanwhile, bottom panel 5 is owing to have joint-cutting 6 and folding line 7, also amounted to into tabular, thereby make whole packing box be folded into tabular, helped storage and transportation.

In the time will using the packing box article-containing, packing box is launched into state shown in Figure 1 gets final product.For making packing box more firm, can in inner casing, place a carboard (not drawing among the figure) that is complementary with rectangle framework 4, also available glue or Double-face gummed paper etc. are bonding with

other plate

52,53,54 and the base plate 1 of bottom panel 5.

In another embodiment, arbitrary plate and base plate 1 in bottom panel 5 other three

plates

52,53,54 is bonding, and other structure is same as the previously described embodiments.

In another embodiment, another group diagonal angle that terminates in rectangle frame body 4 is worked at the two ends of joint-cutting, and two sections folding lines overlap with the angular bisector at all the other two angles respectively, and other structure is same as the previously described embodiments.

In another embodiment, with the rectangle framework of general parallelogram framework or the alternative the foregoing description of prismatic framework, its shape is different with the foregoing description, but structure is identical.

In addition, also available general quadrangle framework substitutes the rectangle framework, and necessary condition is that this quadrangle has the length sum of a pair of adjacent side to equal another length sum to adjacent side.
