Problems solved by technology

But the existing insulation box is usually made of foamed plastics, so it is easy to damage, and some insulation boxes are wrapped with iron sheet or aluminum sheet outside the foamed plastics
However, because it cannot be fully adhered to the foam plastic, it is easy to sag or bulge under pressure, which affects the appearance, and the rigidity is still poor
In addition, the use of metal sheath will form a thermal bridge, which will reduce its overall thermal insulation performance
In addition, the existing structural cover is usually threaded, which is slow to open and fasten, which will affect the delivery time of the delivery staff

Embodiment 1

[0023] Such as figure 1 and figure 2 The shown food container includes a cylinder body 1, a cover body 2, an outer body body 3, an inner body body body 4, a foam heat insulation layer 5, a heat insulation ring 6, a tapered protrusion 7, an L-shaped protrusion 8, L-shaped guide groove 9, clamping groove 10, clamping block 11, spring 12 and heat insulation sealing plate 13.

[0024] Both the cylinder body 1 and the cover body 2 include an outer shell 3 and an inner shell 4, and a polyurethane heat insulation layer is filled between the outer shell 3 and the inner shell 4; the end faces of the outer shell 3 and the inner shell 4 are fixed with heat-insulating rubber ring.

[0025] The inner and outer sides of the cylinder body 1 and the cover body 2 are convexly formed with conical bumps 7, and the heat-insulating rubber ring is formed with L-shaped snap-in protrusions 8 that cooperate with the tapered bumps 7, thereby clamping the heat-insulating rubber ring, and The heat in...

Abstract

The invention discloses a food container and a manufacturing method thereof. The food container comprises a cylinder body and a cover body. Each of the cylinder body and the cover body comprises an outer shell and an inner shell, and a foaming heat insulation layer is filled between the outer shell and the inner shell; and heat insulation rings are fixed on the end surfaces of the outer shell and the inner shell. The food container is simple in structure and convenient to use, the heat insulation performance of the food container can be guaranteed through foaming materials and a heat insulation structure, prestress is formed in the food container through pressure generated during foaming of the foaming materials, and the firmness of the food container is guaranteed.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a food container and a manufacturing method thereof. Background technique [0002] When delivery staff deliver food, they usually stack the food in insulated boxes. But existing thermal insulation box adopts foamed plastics to make usually, therefore easily damaged, and the thermal insulation box that also has is wrapped iron sheet or aluminum sheet outside foamed plastics. However, because it cannot be fully adhered to the foam plastic, it is easy to sag or bulge under pressure, which affects the appearance, and the rigidity is still relatively poor. In addition, the use of metal sheath will form thermal bridges, which will reduce its overall thermal insulation performance. In addition, the existing structural cover is usually threaded, and the opening and fastening are slow, which will affect the delivery time of the food delivery staff. Contents of the invention [0003] In order...
