Description

Collapsible disposable and convenient lunch box

The utility model relates to a kind of lunch box, especially a kind of Paper dinner pail.

China's utility application discloses a kind of folding convenient lunch box for No. 92228368.0, this folding convenient lunch box has by bottom surface, left-right symmetry face, the plane of symmetry folds the box body that forms up and down, and roll at the junction of these four jiaos of fold lines in lunch box cardboard bottom surface especially and have four to prevent to push the fracture by fatigue hole, this lunch box can be folded into a thin slice, therefore has convenient carrying.But this kind lunch box is in that transferred to deployed condition back box mouth place intensity by folded state relatively poor, easily deformable, and inconvenient user uses, and simultaneously, the orthostatic of box body is also relatively poor, be easy in use cave in, thus the defective of existing.

The purpose of this utility model provides a kind of intensity and the collapsible preferably disposable and convenient lunch box of orthostatic.

The purpose of this utility model is by realizing so that the below is military: set up by the mutually bonding box mouth grommet of adhesive sticker and box body at the open topped place of folding papery box body, thereby improve the intensity and the orthostatic of lunch box.Specifically, folding military disposable and convenient lunch box of the present utility model has the folding papery box body of open topped, it is characterized in that being provided with box mouth grommet, the hollow space of described box mouth grommet matches with the open topped of papery box body, have the extension of downward extension in the hollow space edge of box mouth grommet, the inwall of this extension is mutually bonding by adhesive sticker with the outer wall of papery box body.In the utility model, the ring body profile of box mouth grommet (being the shape of ring body outer institute corral) can be circular or multiple shapes such as ellipse, rectangle, its hollow space (being the interior zone along institute's corral of ring body) also can be circular or multiple shapes such as ellipse, rectangle, as long as can match with the open topped of papery box body.Both having played to lower extension of box mouth grommet is fixed in effect on the papery box body with the adhesion of box mouth grommet, helps to strengthen the bulk strength of lunch box again, and its shape can be arbitrarily.With regard to the utility model, before not using lunch box, papery box body and box mouth grommet can separated attitudes, and the adhesive sticker that is used for adhesion box body and box mouth grommet extension can be defaulted in the box mouth grommet extension suitable position place of box body outer wall (but also can default in).Because the papery box body itself is folding, and box mouth grommet also is flat (it can be set to collapsible to lower extension), so the two takes up space minimumly, is convenient to transport and deposit.When needs use lunch box, only the papery box body need be strutted and be stereo structure, again the open topped place of box mouth grommet cover to the papery box body, to default in box mouth grommet protects paper to the adhesive sticker of (or on box body outer wall) on the lower extension and removes, make this be adhered to the outer wall of papery box body, can be assembled into lunch box of the present utility model to lower extension.In addition, in order to allow papery box body and box mouth grommet make up better, the flange of outside turnover can also be set at the box mouth place of papery box body further, after the lunch box assembling was finished, the lower edge of this flange can contact with the upper surface of box mouth grommet.Like this, hang over effect on the box mouth grommet because set flange can play button, therefore can strengthen being connected of box body and box mouth grommet, simultaneously, being provided with of flange can also allow the profile of lunch box more attractive in appearance.

Compared with the aforementioned existing similar products, convenient mess tin of the present utility model had both kept the characteristics transporting and deposit be convenient to, and made the intensity of lunch box and orthostatic obtain tangible improvement again, thereby had improved the practical value of product.

Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.

Fig. 1 is the structural representation of convenient mess tin among the embodiment.

Fig. 2 is the structural representation (overlooking state) of box mouth grommet.
