Abstract

The utility model relates to a paper box, particularly a paper box formed by folding a complete piece of thick paper. The utility model is characterized in that the surface of the thick paper is coated with a thin layer of transparent PVC nontoxic paint, the box is made by folding a complete piece of thick paper, wherein, the four edges of the box are side straight edges, and eight edges of the box are side sloped edges. Approximate trapezoid rims with folds in the middle are formed outside the side straight edges, folds are formed on the surface coated with a thin layer of transparent PVC paint, and the box is folded according to the folds. The utility model is folded by a complete piece of thick paper without joint seams, and the surface of the thick paper is coated with a thin layer of transparent PVC nontoxic paint, so the utility model can effectively avoid soaking and out leakage of the liquid articles in the box.

Description

Fold type paper external packing cutlery box

The utility model relates to a kind of carton, particularly a kind of carton that utilizes a complete ground paper to be folded to form, and specifically, its base does not have seam, and has fabulous leak preventing effect.

Existing paper lunch-box, in order to make it be easy to manufacture, after all adopting folding, the junction of bottom utilize staple or other modes to peg or cling and form side to form the box-like article-containing that comes, this box paper does not have the leakproof ability and seam is arranged, when meeting splendid attire and having the article of liquid, liquid just might soak into box body or spill from each limit seam of box.

The utility model is at the existing in prior technology shortcoming, its objective is a kind of box that utilizes ground paper as the splendid attire canteen of design, can avoid the liquid immersion carton of institute's splendid attire and no seam to avoid the liquid leakage of splendid attire.

Principle of the present utility model is to utilize doing the transparent as thin as a wafer PVC non-toxic coatings of box ground paper surface coverage one deck, it has high temperature and can not dissolve for 140 ℃, tasteless and can not produce pollution, make ground paper have the leakproof characteristic, utilization forms folding line on ground paper, a complete ground paper is converted into box-like by folding line, utilizes High Temperature High Pressure will roll over the folding unnecessary part that the back forms again and stick on side, have the paper lunch-box of good leak preventing effect with formation.

Of the present utility model being characterised in that at the transparent as thin as a wafer PVC non-toxic coatings of surface coverage one deck of the ground paper of making box, box is to make by a complete ground paper is folding, it is the side straight flange that four limits are wherein arranged, it is the skew back limit that eight limits are arranged, outside the side straight flange, form and be similar to trapezoidal shape and the middle edge that has folding line, be formed with folding line on the surface that is coated with transparent as thin as a wafer PVC, press folding line and fold and the formation box.The particular location of above-mentioned folding line is for there being an oblong base folding line at the middle part of ground paper, the limit of folding line is corresponding parallel with four side straight flanges, form a side folding line at the middle part of each hypotenuse, hypotenuse and straight flange intersection and form a folding line with the cooresponding angle of base folding line line, folding line by the hypotenuse middle part is turned up, make four straight flanges curve vertical naturally and the formation carton, the lap that hypotenuse forms through folding fixedly sticks on side by High Temperature High Pressure, and the trapezoidal portions that is similar to that forms outside the side straight flange is also pasted and the formation edge by the folding line doubling.

Further illustrate the utility model below in conjunction with accompanying drawing embodiment;

Fig. 1 is the expansion drawing of the utility model box.

1 for being coated with the ground paper of transparent as thin as a wafer PVC non-toxic coatings among the figure, and 2 is the side straight flange, and 3 is the skew back limit, and 4 is the side folding line, and 5 is bottom fold, and 6 is the edge, and 7 is the edge folding line.

The utility model is at the transparent as thin as a wafer PVC non-toxic coatings of surface coverage one deck of the ground paper of making box, can prevent liquid immersion by actv., and can strengthen the intensity of ground paper, box is by a complete ground paper 1 folding making, it is that side straight flange 2, eight limits are skew back limit 3 that four limits are wherein arranged, and forms to be similar to trapezoidal shape and the middle edge that has folding line outside the side straight flange, be formed with folding line on the surface that is coated with transparent as thin as a wafer PVC, press folding line and fold and the formation box.The particular location of above-mentioned folding line is for there being an oblong base folding line 5 at the middle part of ground paper, the limit of bottom fold is parallel with four side straight flanges, and the length that is shorter in length than corresponding parallel sides straight flange on each limit of bottom fold, it is bigger to make box turn up the back upward opening by folding line, form a side folding line 4 at the middle part of each hypotenuse, hypotenuse and straight flange intersection and also form a side folding line 4 with the cooresponding angle of base folding line line, folding line by the hypotenuse middle part is turned up, make four straight flanges curve vertical naturally and the formation carton, the lap that hypotenuse forms through folding fixedly sticks on side by High Temperature High Pressure, the trapezoidal portions that is similar to that forms outside the side straight flange is fixed by folding line 7 doublings and High Temperature High Pressure and is formed edge 6, and the certain width that edge 6 forms is favourable to be coated with film thereon or to add a cover and make the box sealing.

The utility model is made by a complete ground paper is folding, no seam, and the transparent as thin as a wafer PVC non-toxic coatings of one deck is arranged in the ground paper surface coverage, and the energy actv. is avoided being loaded with in the box soaking into of liquid article and is leaked outside.

Above embodiment is used for further illustrating the utility model, can not limit Applicable scope of the present utility model in view of the above, the variation of any equivalent technologies feature of doing according to above-mentioned principle of the present utility model all should be included within the utility model technology category.
