Abstract

The utility model relates to a paper box, particularly a paper box folded by a complete piece of paper, which is characterized in that the surface of the thick paper for making the box is coated with a thin layer of transparent PVC nontoxic paint, and the box is folded by a complete piece of thick paper. The complete paper is an octagon, wherein, four edges of which are side straight edges and the other four edges of which are side inclined edges. Side edge folds are formed on the surface coated with a thin layer of transparent PVC paint, and the box is folded and formed 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 the soaking and out leakage of the liquid articles in the box.

Description

The fold type paper lunch-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 leakproof ability and often blow-by of seam crossing, when meeting splendid attire and having the article of liquid, liquid just might soak into box body or spill from each limit seam crossing 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 box ground paper surface to cover the transparent as thin as a wafer transparent as thin as a wafer PVC non-toxic coatings of 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 HTHP 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, complete paper is octagon, wherein four limits are the side straight flange, four limits are the skew back limit in addition, be formed with folding line on the surface that is coated with transparent as thin as a wafer PVC non-toxic coatings, press folding line and fold and the formation box.The particular location of above-mentioned folding line is for there being a rectangle base folding line at the middle part of ground paper, the limit of folding line is parallel with octagonal four straight flanges, middle part at each hypotenuse forms a side folding line perpendicular to hypotenuse, hypotenuse forms a folding line with the straight flange intersection with the corresponding angle line of base folding 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 HTHP.

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

Fig. 1 is the expanded view 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.

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 effectively prevent liquid immersion, and can strengthen the intensity of ground paper, box is by a complete ground paper 1 folding making, complete paper is octagon, and wherein four limits are side straight flange 2, and four limits are skew back limit 3 in addition, 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 a rectangle base folding line 5 at the middle part of ground paper, the limit of bottom fold is parallel with octagonal 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, middle part at each hypotenuse forms a side folding line 4 perpendicular to hypotenuse, hypotenuse also forms a side folding line 4 with the straight flange intersection with the corresponding angle line of base folding 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 HTHP.

The utility model is made by a complete ground paper is folding, and 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 can effectively avoid being loaded with in the box soaking into and leaking outside of liquid article.

Above embodiment is used for further illustrating the utility model, can not limit the scope of application 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.

Claims

1, a kind of fold type paper lunch-box, it is characterized in that at the transparent as thin as a wafer PVC non-toxic coatings of surface coverage one deck of doing the box ground paper, box is to make by a complete ground paper is folding, complete paper is octagon, wherein four limits are the side straight flange, four limits are the skew back limit in addition, are 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.

2, fold type paper lunch-box according to claim 1, the particular location that it is characterized in that folding line is for there being a rectangle base folding line at the middle part of ground paper, the limit of folding line is parallel with octagonal four straight flanges, middle part at each hypotenuse forms a side folding line perpendicular to hypotenuse, hypotenuse forms a folding line with the straight flange intersection with the corresponding angle line of base folding 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 HTHP.
