Abstract
A disposable square lunch box comprises a square box wall and a box bottom arranged under the box wall. The disposable square lunch box is characterized in that the square lunch box is indented from the upper edge of the box wall to the box bottom portion, and longitudinal reinforcing ribs are arranged on the four edges. Heat dissipation corrugated concavo-convex faces extending from the box wall to the box bottom portion are arranged between the reinforcing ribs on four sides of the box wall. The disposable square lunch box has the advantages that the step-type reinforcing ribs reinforce the edges which are most vulnerable to damage on the square lunch box. Improvement of a pressure-bearing limit of the whole lunch box is facilitated. The corrugated concavo-convex faces facilitate heat dissipation and avoid that the heat is directly conducted to the surfaces of the box wall to burn users.
Description
[technical field]
The utility model relates to daily people's livelihood product, relates in particular to a kind of boxed cassette/snack box/lunch box.
[background technology]
Disposable lunch box is usually used in restaurant's packing, the packing fast food, usually disposable lunch box is the type of promptly throwing, so be particular about with the best lunch box of minimum cost manufacturing property, and material must environmental protection to the human body nonhazardous, disposable lunch box is made box body with less material usually, right rear box wall is thin, generally impulsive force that can bear and pressure are limited, under the heavier situation of the food of splendid attire, need very careful, in case surpassing the ultimate strength that can bear will be broken, the place that square lunch box is different from the round bowl-shaped lunch box is that the round bowl-shaped lunch box is owing to structure center of circle symmetry, the stressed rectangular distribution of circumferencial direction, the collapse point that does not have the pressure maximum, and square lunch box is bearing aspect the pressure limit not enoughly to some extent, and four corner crest lines are the weakest places, go out fragmentation from crest line easily to come, in addition because wall is thin, when the very hot food that dress has just taken the dish out of the pot, be inconvenient to hold and take because at the bottom of the box and the box wall temperature very high, catch to touch and can iron hand this moment, wishes to improve these defectives of lunch box.
[summary of the invention]
The utility model has proposed a kind of gradual tension pressure that structure can improve the lunch box edge that draws high especially at above problem, and rapidly heat radiation does not allow the disposable square lunch box that scalds one's hand at the bottom of box wall and the box.
The technical solution of the utility model is: the box wall of a kind of disposable square lunch box, the side's of comprising build and at the bottom of the box of box wall bottom, it is characterized in that, described square lunch box divides indentation in the bottom from box wall upper limb to box, the crest line place is provided with reinforced rib longitudinally in corner, four roads, on four faces of box wall, have the radiatinig corrugated male and fomale(M﹠F) between the described reinforced rib, described radiatinig corrugated male and fomale(M﹠F) extends to the box bottom from the box wall and divides.
Described reinforced rib has some roads, present from top to bottom the stepped of indentation gradually, go up together to having a cascaded surface between one down, the base that locks one reinforced rib is down together so just arranged, compacted successively then, form powerful fastening force, improved the pressure limit on corner angle limits, strengthened the integral body heavy burden ability to bear of lunch box.
Described radiatinig corrugated male and fomale(M﹠F), present wave-like from the section of crosscut box wall, in splendid attire food, form the space, this space helps heat radiation on the one hand, allow the high food of temperature can not be attached at the bottom of box wall and the box on the one hand in addition comprehensively, so can not allow the temperature at the bottom of box wall and the box too high, make things convenient for the people when having packed the food of high-temperature, can take up with the lunch box end easily yet.
The beneficial effects of the utility model: the notch cuttype reinforced rib has been strengthened the weakest breakable angular edge of square lunch box, help strengthening single-piece and bear limit of pressure, described ripple male and fomale(M﹠F) then is that convenient heat radiation, isolation high temperature directly pass to and leads the box wall surface, prevents that the people from scalding.
[description of drawings]
Fig. 1 is the utility model structural representation.
Wherein: 1, box wall; 2, at the bottom of the box; 3, reinforced rib; 4, radiatinig corrugated male and fomale(M﹠F); 5, cascaded surface.
[specific embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.
The box wall 1 of a kind of disposable square lunch box, the side's of comprising build and at the bottom of the box of box wall 1 bottom 2, it is characterized in that, described square lunch box from box wall 1 upper limb to box at the bottom of 2 parts present the indentation shape, the crest line place is provided with horizontal reinforced rib 3 in corner, four roads, on 1 four faces of box wall, have radiatinig corrugated male and fomale(M﹠F) 4 between the described reinforced rib 3, described radiatinig corrugated male and fomale(M﹠F) 4 extends to 2 parts at the bottom of the box from box wall 1.
Described reinforced rib 3 has some roads, present from top to bottom the stepped of indentation gradually, go up together to having a cascaded surface 5 between one down, the base that locks one reinforced rib is down together so just arranged, compacted successively then, form powerful fastening force, improved the pressure limit on corner angle limits, strengthened the integral body heavy burden ability to bear of lunch box.
Described radiatinig corrugated male and fomale(M﹠F) 4, present wave-like from the section of crosscut box wall, in splendid attire food, form the space, this space helps heat radiation on the one hand, allow on the one hand the high food of temperature can not be attached at the bottom of box wall 1 and the box 2 in addition comprehensively, so can not allow at the bottom of box wall 1 and the box 2 temperature too high, make things convenient for the people when having packed the food of high-temperature, can take up with the lunch box end easily yet.
The beneficial effects of the utility model: the notch cuttype reinforced rib has been strengthened the weakest breakable angular edge of square lunch box, help strengthening single-piece and bear limit of pressure, described ripple male and fomale(M﹠F) then is that convenient heat radiation, isolation high temperature directly pass to and leads the box wall surface, prevents that the people from scalding.
