The purpose of this utility model can realize by following technical proposal: a kind of antistaling box, comprise casing and case lid, casing and case lid include skin, internal layer, heat-insulation layer, the opening part of described casing is provided with the bead that extends out, bead and casing are connected as a single entity, heat-insulation layer on the described casing extend in the bead, and the heat-insulation layer when case lid is closed in the case lid extend in the range of sizes of described bead.Described bead is to stretch out towards the outside of casing, has increased the area of casing open end like this, and binding face is big between casing and the case lid, can guarantee fresh-keeping fresh-keeping effect.Described heat-insulation layer is generally made by foamed materials.

In the described antistaling box, described casing internal layer is provided with towards the outstanding projection of heat-insulation layer direction, is provided with the pit that matches with projection on heat-insulation layer.

In the described antistaling box, described casing internal layer is provided with some to slot, dividing plate that can the insertion activity in every pair of slot.

In the described antistaling box, establish on the described case lid internal layer and the similar cushion of described bead cross sectional shape, on the bead upper surface, be provided with the convex body that matches with cushion, close case lid after the convex body roof pressure on cushion.

In the described antistaling box, the cross section of described convex body is triangular in shape.

In the described antistaling box, described convex body and casing internal layer are connected as a single entity.

In the described antistaling box, be provided with two handles on the described casing symmetrically, handle is shaped as frame, on two outer side edges of handle, be provided with chute,, on casing, be provided with two permanent seats corresponding to each handle, permanent seat is provided with set pin, and set pin is plugged in the chute with gap.

In the described antistaling box, be provided with the hasp that is used to fasten both between described casing and case lid, ling hinge is connected on the connecting panel, and connecting panel is hinged on the casing.

Compared with prior art, the beneficial effects of the utility model are:

Be provided with the bead that is connected as a single entity with casing in the casing open end, bead is the outside of stretching to casing, the bead that is provided with has increased the area of casing open end, after case lid is enclosed on the casing, binding face between case lid and the casing is big, good airproof performance between case lid and the casing can guarantee the fresh-keeping effect of antistaling box.

Fig. 3 is the structural representation of hasp in this antistaling box.

The specific embodiment

Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.

See Fig. 1, Fig. 2, Fig. 3, the structure of the utility model antistaling box comprises case lid 1 and the casing 3 that is hinged together, and case lid 1 and casing 3 include skin, internal layer and heat-insulation layer, and wherein heat-insulation layer is between inside and outside layer.

Casing 3 is for having the prism of an open end, and above-mentioned case lid 1 can be enclosed in the open end on the casing 3.The structure of casing 3 comprises cabinet insulation layer 31, casing outer 32 and casing internal layer 33, open end at casing 3 is provided with the bead 2 that stretches out towards the outside, bead 2 is connected as a single entity with casing 3, its structure also with the structural similitude of casing 3 wall bodies, and described cabinet insulation layer 31 extend in the bead 2.Be provided with outstanding projection 14 on the upper surface of bead 2, the shape of projection 14 is similar to the shape of casing 3 cross-sectional planes, and the casing skin 32 on projection 14 and the bead 2 is connected as a single entity, and its cross sectional shape is triangular in shape.

The structure of case lid 1 also with the wall body structural similitude of casing 3, also comprise case lid heat-insulation layer 11, case lid outer 12 and case lid internal layer 13, when case lid 1 was closed, the case lid heat-insulation layer 11 in the case lid 1 extend in the range of sizes of bead 2.Also be provided with the cushion 10 that matches with above-mentioned prominent body 14 on case lid internal layer 13, cushion 10 is embedded in the groove set on the case lid internal layer 13.After case lid 1 was closed, projection 14 roof pressures were on cushion 10.
