[0005] The container cover is provided with a honeycomb paper core interlayer in the cover surface, and the cover surface comprises an inner cover surface and an outer cover surface arranged at intervals, the honeycomb paper core interlayer is connected and supported between the inner cover surface and the outer cover surface, and the space between the inner cover surface and the outer cover surface is divided into a plurality of units which are not conductive to each other by the honeycomb paper core interlayer.

[0006] The container body and the container cover are both polygonal or circular.

[0007] The container body and the container cover are both vacuum adsorbed with a film layer.

[0008] The utility model discloses a beneficial effect is improved heat preservation paper container, through the bottom and the peripheral wall in the container body all are equipped with honeycomb paper core interlayer, and the honeycomb paper core interlayer divides the space in the bottom and the peripheral wall in the container body into several units that do not conduct mutually, limits the air circulation in the interior, reduces the heat loss, plays the heat preservation effect, and the lid surface in the container lid is equipped with honeycomb paper core interlayer, and the heat preservation effect is further enhanced, and the honeycomb paper core interlayer is as the heat preservation layer, and the cost is low, environmental protection recyclable.
