Abstract

The utility model relates to a packing box, particularly a light-duty fresh keeping box which is made of foam and plastic. The reinforced fresh keeping box of the utility model is composed of a box body, a box cover which is matched with the size of the box body, and partition boards which are provided with through-holes, wherein, the four sides of the box body and the bottom of the box body are provided with stiffening ribs; the bitten place of the box cover and the box body has U-shaped structure; the partition boards of the inner cavity of the box body are arranged at the convex areas of the stiffening ribs of the box body. Because the box body of the utility model has reinforcing structure to cause the box body to have higher pressure resistance and the box body not to be easily damaged in the process of move and transportation and have a much more beautiful appearance shape. The same thick sides of the box body have no step arrangement to cause the entire box body to have simple structure. The special double interfaces of the box cover and the box body cause the box body and the box cover to be sealed better and to have much more visible thermal insulation and fresh keeping effects. The utility model is suitable for long distance transportation.

Description

The heavier-duty antistaling box

The utility model relates to a kind of packing chest, especially relates to a kind of light-duty antistaling box of being made by foamed plastic.

Chinese patent application CN2491383Y (number of patent application is ZL01206499.8) has announced " a kind of bright bacterium antistaling box ", include rectangular box and case lid, it is characterized in that, be provided with step at the inner chamber upper wall of casing, be placed with a dividing plate on step, opening on dividing plate has open-work.The casing of this application is common structure, and intensity is relatively poor relatively, and case lid is common structure, can only reach general effect of heat insulation.

The purpose of this utility model is intended to overcome the deficiencies in the prior art, and a kind of antistaling box with high strength and better effect of heat insulation is provided.

Heavier-duty antistaling box described in the utility model by casing, with the case lid of box sizes coupling, open and form by the dividing plate of open-work, the casing four sides is provided with reinforced rib with the bottom, case lid and casing interlock place are " ∏ " shape structure, and the dividing plate of cabinets cavity is positioned over the boss of casing reinforced rib.

Be to wait thick structure around the described casing; Described reinforced rib extends upwardly to the height place of casing 6/10ths to 8/10ths all around along casing.

The utility model is because casing is an additional strengthening, make that the casing resistance to pressure is higher, moving, be not easy in the transportation to damage, but also having face shaping comparatively attractive in appearance, the box body wall uniform thickness has saved the setting of step, makes whole box body simple in structure, the special dual interface of case lid and casing, make that the sealing of casing and case lid is better, heat insulation fresh-keeping effect is more remarkable, is suitable for long-distance transport.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the utility model schematic appearance.

Fig. 2 is the utility model case lid longitudinal profile scheme drawing.

Fig. 3 is the utility model dividing plate longitudinal profile scheme drawing.

Fig. 4 is the utility model casing longitudinal profile scheme drawing.

Among the figure:

1-casing, 2-case lid, 3-dividing plate, 4-open-work, 5-∏ shape interface, 6 reinforced ribs.

Embodiment 1:

Heavier-duty antistaling box described in the utility model is made of casing 1, case lid 2 and dividing plate 3.The casing four sides is provided with reinforced rib 6 with the bottom, being set to of reinforced rib is pressed into concaveconvex structure with the foamed plastic of uniform thickness, common single root of Dahurian angelica mouth structure is changed in interlock place of case lid and casing, be " ∏ " shape structure, make two root of Dahurian angelica mouth structures that are combined between casing and the case lid, can reach even more ideal effect of heat insulation, thereby make fresh-keeping effect better.Described reinforced rib extends upwardly to the height place of casing 6/10ths to 8/10ths around the casing, and the dividing plate 3 of inner chamber directly is positioned over the boss of casing reinforced rib, has saved setting up or the device of other fixed placement dividing plates of step.

During use bright bacterium is placed on lower box, then dividing plate is placed on the bossing of casing reinforced rib, on dividing plate, place ice cube, build case lid, cold air is circulated in whole box body by the open-work on the dividing plate 4.

Claims

1, a kind of heavier-duty antistaling box, by casing (1), with the case lid (2) of box sizes coupling, open and have the dividing plate (3) of open-work to form, it is characterized in that the casing four sides is provided with reinforced rib (6) with the bottom, case lid and casing interlock place are " ∏ " shape structure, and the dividing plate of cabinets cavity is positioned over the boss of casing reinforced rib.

2, heavier-duty antistaling box according to claim 1 is characterized in that around the described casing be to wait thick structure.

3, heavier-duty antistaling box according to claim 1 is characterized in that described reinforced rib extends upwardly to the height place of casing 6/10ths to 8/10ths all around along casing.
