The utility model discloses a reach a technical scheme that above-mentioned purpose adopted and be: a disposable lunch box comprises a box body and a box cover, wherein one end of the box body is provided with an opening, and the box cover can cover the opening of the box body; the box body and the box cover are both made of concrete, a protective film is arranged on the surface of the inner cavity of the box body, and the protective film is arranged on at least one surface of the box cover facing the inner cavity of the box body.
Furthermore, the edges of at least two edges on the opening surface of the box body are provided with clamping grooves, and the box cover seals the opening surface of the box body through the clamping grooves.
Furthermore, the concrete is a micro foaming structure, a plurality of cavities are contained in the concrete, and the diameter of each cavity is smaller than the thickness of two-thirds of the wall thickness of the box body.
Further, the micro foam structure is a honeycomb foam structure.
Further, the concrete is foamed concrete.
Furthermore, the concrete is distributed with fibers.
Further, the protective film is one or a mixture of edible tin foil, paper, metal and plastic.
Furthermore, a rubber pad is arranged on the box cover.
Further, the length of the edge on the opening on the same side of the box body is greater than that of the edge at the bottom of the box body.
Furthermore, the wall thickness of the box body and the box cover is 1-5 mm.
The utility model can greatly reduce the use of plastic, paper and wood materials; the concrete material which is surplus in the industry is utilized newly, so that various environmental hidden dangers are greatly reduced, and the environment is protected; and the production price is reduced; and the manufactured disposable product has hard texture and is safe and convenient to use.
Drawings
FIG. 1 is a schematic view of a preferred embodiment of the present invention;
fig. 2 is a partial cross-sectional view of the preferred embodiment of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings and embodiments:
as shown in fig. 1, a disposable lunch box comprises a box body 1 and a box cover 3, wherein one end of the box body 1 is provided with an opening, and the box cover 3 can cover the opening of the box body 1; the box body 1 and the box cover 3 are both made of concrete, the surface of the inner cavity of the box body 1 is provided with a protective film 2, and the box cover 3 is at least provided with the protective film 2 at one surface facing the inner cavity of the box body 1.
The edges 11 of at least two edges on the opening surface of the box body 1 are provided with clamping grooves 4, and the box cover 3 seals the opening surface of the box body 1 through the clamping grooves 4. The box cover 3 is inserted into the opening surface of the box body 1 through the clamping groove 4 to seal the opening.
The box cover 3 is provided with a rubber pad, after the box cover is covered, the rubber pad is sealed, and the box cover 3 and the inner cavity of the box body 1 form a closed space. The rubber pad can be arranged along the edge of the box cover 3, and also can be arranged on the edge of the inner cavity wall of the box body 1 corresponding to the box cover 3.
In order to reduce the weight of the box body 1, the concrete is of a micro foaming structure, a plurality of cavities 12 are contained in the concrete, and the diameter of each cavity 12 is smaller than the wall thickness of the box body 1. In this embodiment, as shown in fig. 2, the micro-foaming structure is a honeycomb-shaped foaming structure, the concrete includes a plurality of cavities 12 with different sizes, and the maximum diameter of the cavity 12 is smaller than two-thirds of the thickness of the wall of the box body 1. The whole material has a large number of micro-cavity characteristics. The overall density is reduced considerably, not only the weight of the cassette can be reduced, but also the cost. In this embodiment, the concrete is foamed concrete. The foamed concrete is usually a porous material prepared by mechanically preparing foam from a foaming agent aqueous solution, adding the foam into slurry consisting of siliceous materials, calcareous materials, water, various additives and the like, mixing, stirring, casting, molding and curing.
Or injecting air during the material forming process to form a structure with individual vacuoles, or adding sublimable material to fill space during the preparation process, and heating to sublimate the material after forming to generate the vacuoles. The structure is preferably a honeycomb structure.
In order to increase the toughness of the box body 1, fibers are distributed in the concrete to prevent the concrete from cracking. The concrete can be added with one or more gelled materials, and the tougher disposable article is made by utilizing the characteristics of cheapness and toughness of the concrete.
The protective film 2 is one or a mixture of food-grade tinfoil, paper, metal and plastic, so that the lunch box is safe.
In order to stack the box body 1, the following settings are made: the length of the edge on the opening on the same side of the box body 1 is greater than that of the edge at the bottom of the box body 1. The box body 1 is in an inverted frustum shape, so that the box body 1 can be stacked conveniently.
The wall thickness of box body 1 and lid 3 is 1 ~ 5 millimeters, can set up to: 1 mm, 1.1 mm, 2.3 mm, 3.0 mm.
The utility model can greatly reduce the use of plastic, paper and wood materials; the concrete material which is surplus in the industry is utilized newly, so that various environmental hidden dangers are greatly reduced, and the environment is protected; and the production price is reduced; and the manufactured disposable product has hard texture and is safe and convenient to use.
