Abstract

The utility model relates to a folding food packing box, which comprises a bottom, a front, a back, a left and a right side walls and an upper cover plate, which are abutted through fold lines. Four corners of every adjacent side walls are provided with a foldable sealing structure, which comprises two symmetrical sealing parts provided with a common fold line. The sealing parts are folded along the common fold line to turn over outward and are abutted on the corresponding side wall, and one part is overlapped mutually. The upper part of a box body is provided with a handle. Because the box body of the folding food packing box can effectively prevent the liquid of the contained food from permeating and overflowing, so the utility model has the advantages of safety, sanitation, convenient use, portability and no pollution to the environment.

Description

Collapsible food package box

The utility model relates to a kind of food package box.

The packing box that is loaded with solid and liquid mixing food at present generally all is to be formed by loam cake made of plastic and box body hasp.The packing box of this pattern is widely used in catering industry, particularly the fast food industry.But because it does not have the failure-free hermetically-sealed construction, juice wherein is easily excessive and cause the trouble of carrying, and simultaneously because plastics are a kind of nondegradable materials, it pollutes the environment after being abandoned by disposable use.For fear of the excessive trouble of juice be easy to carry, generally also want the nondegradable plastic bag of overcoat in use, not only use inconvenience, and plastic bag also can cause environmental pollution.

Therefore, the purpose of this utility model provides a kind of food package box that prevents liquid spill, easy to carry and compliance with environmental protection requirements.

For achieving the above object, the utility model provides a kind of folding food package box, and it comprises: the upper cover plate of a bottom, sidewall all around and left-right and front-back, and they are by corresponding broken line adjacency, be characterized in that four bights between each adjacent wall have folding hermetically-sealed construction.

Further characteristics of the present utility model are: described hermetically-sealed construction comprises that two have the symmetrical hermetic unit of public broken line; Described symmetrical hermetic unit along the superimposed back of described public broken line outwards upset fit on the respective side walls and some is overlapped; Described each sidewall is trapezoidal, and the base or is gone up less than the bottom greater than the bottom in base on it; Or each sidewall is rectangle or square; Comprise that also one is located in relative superimposed hermetically-sealed construction in box body top and the carry climbing on the sidewall.

Adopt technique scheme of the present utility model, can adopt to become to contain to constitute each key element of above-mentioned box body and partly launch blank, be folded into three-dimensional echelon form along corresponding broken line then through finished sheet trimming.Because four bights of the box body of this folding food package box have folding hermetically-sealed construction, therefore can effectively prevent to be contained in interior solid of packing box and the liquid in the liquid mixing food, for example infiltration of the soup in the food and excessive, fool proof health; Because the packing box mouth is fitted with carry climbing, can carry with portable, uses easy to carry; Because the material of making packing box is the paper through processing, can reclaims after the disposable use and can not cause pollution environment.

One preferred embodiment specifically describes to the utility model below in conjunction with accompanying drawing, so that clearlyer understand the purpose of this utility model, characteristics and advantage.

Fig. 1 is the block diagram of the collapsible food package box of the utility model one preferred embodiment;

Fig. 2 is the scheme drawing of last folded state that the folding process of Fig. 1 embodiment is shown;

Fig. 3 is Fig. 1 embodiment begins folded state from deployed condition a scheme drawing;

Fig. 4 is the plane outspread drawing of Fig. 1 embodiment.

Fig. 1 to Fig. 4 illustrates the collapsible food package box 1 of the utility model one preferred embodiment, it comprises: four bights between a bottom 9, front side wall 2 ', rear wall 2, left side wall 3, right side wall 4 and upper left cover plate 7, upper right cover plate 8, preceding upper cover plate 6, back upper cover plate 5 and each adjacent wall have folding hermetically-sealed construction 10 ', and they adjoin each other by corresponding broken line 12 to 17.Described hermetically-sealed construction 10 ' comprises that two have the symmetrical hermetic unit 10 and 11 of public broken line 14, and an end points 18 of broken line 14 is the common vertex of adjacent wall and bottom; Described symmetrical hermetic unit 10 and 11 along public broken line 14 superimposed backs outwards the upset of (arrow as shown in Figure 2) direction fit to respective side walls, also some is overlapped on the sidewall 2 ' and 2 before and after for example, as shown in the figure.Described each sidewall is trapezoidal, on it base 15,17 respectively greater than bottom 12,16 so that folding back forms cone-shaped.Certainly, also can form the base, so that folding back forms the reverse taper shape less than the bottom.When last base equals the bottom, promptly sidewall is rectangle or during square, then forms cuboid or cubic.In addition, described hermetically-sealed construction 10 ' is quadrangle, and adjacent adjacent side 20,21 folding backs are concordant substantially with last base 15, as shown in Figure 1.Certainly, described hermetically-sealed construction 10 ' can also be other configuration.Interpolation slit 17 and eye-splice 16 are formed respectively at the top at last front shroud 6 and last back shroud 5, with closed box mouth when eye-splice embeds interpolation slit.For easy to carry, on the superimposed partial sum sidewall of the relative hermetically-sealed construction in box body top, can wear a carry climbing 22.Fig. 4 is 1 a plane outspread drawing of collapsible food package box of the present utility model.Fig. 3 and Fig. 2 represent the folding process that begun by deployed condition.As shown in Figure 3, carry out along last bottom 15,17 and 12,16 in the direction of arrows uprightly folding; Make adjacent hermetic unit 10 and 11 inside face relative superimposed simultaneously to form state as shown in Figure 2 along public broken line 14; Then, the hermetically-sealed construction 10 ' after folding is fitted on the sidewall 2 ', 2 of front and back by the outside upset of the direction of arrow shown in Figure 2, as shown in Figure 1, and with eye-splice 16 embedding interpolation slits 17.Can wear a carry climbing 22 on the sidewall before and after the superimposed partial sum of relative hermetically-sealed construction then, perforation can be pre-formed on the relevant position of hermetic unit on the expansion drawing and front and back sidewall.In the present embodiment, this carry climbing 22 is to be located in relative front and back sidewall direction, but if hermetically-sealed construction is turned to the situation on the sidewall of the left and right sides, then carry climbing 22 should be located in left and right sides sidewall direction.Can see that the process of box body that is folded into stereo structure from the blank that launches the plane is quite simple and convenient.
