Detailed Description

In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

As shown in the figures, the present embodiment discloses a thermal insulation paper can, which comprises a paper can body 1, wherein the can body 1 comprises an inner layer 10 and an outer layer 11, a sealed insulation space is arranged between the inner layer 10 and the outer layer 11, and the insulation space comprises a first empty area 12 between the side walls of the inner layer 10 and the outer layer 11 and a second empty area 13 between the bottom walls of the inner layer 10 and the outer layer 11. The paper tank in this embodiment, through the setting in first dead zone 12 and second dead zone 13 for keep apart almost completely between the inlayer 10 of the jar body 1 and the skin 11, thereby prevent the heat via jar body 1 direct conduction, also need slowly carry out the heat conduction through the air in the isolation space, thereby effectively improved jar body 1's the effect of keeping apart the temperature, can not increase too big cost burden for the paper tank moreover. For example, when ice cream is filled in the tank body 1, air with relatively high external temperature cannot directly contact with the inner layer 10 of the tank body 1, and only when the temperature of the air in the isolation space is low enough, the external heat can be diffused into the isolation space, so that the temperature of the ice cream in the inner layer 10 is influenced through the distance between the isolation spaces, and the melting time of the ice cream is effectively prolonged.

Specifically, a stopper 110 abutting against the sidewall of the inner layer 10 is provided on the top of the outer layer 11, and the first empty region 12 is formed by separating the sidewall of the inner layer 10 and the sidewall of the outer layer 11 by the stopper 110. In this embodiment, the barrier 110 separates the sidewalls of the outer layer 11 and the inner layer 10 to form the first vacant region 12. Preferably, the barrier portion 110 is formed by inward curling of the top of the outer layer 11, which does not require additional material cost, and the paper curling process is relatively mature and easy to implement.

More specifically, the edge of the bottom wall of the inner layer 10 is provided with a first supporting leg 100, and the first supporting leg 100 separates the inner layer 10 from the bottom wall of the outer layer 11 to form a second empty area 13. In this embodiment, the first supporting leg 100 not only improves the supporting strength of the inner layer 10, but also prevents the inner layer 10 from directly contacting the bottom wall of the outer layer 11. Preferably, the first supporting leg 100 is formed by inward curling of the bottom of the inner layer 10.

Further, the edge of the bottom wall of the outer layer 11 is provided with a second supporting leg 111 for supporting the can body 1. In this embodiment, through the setting of second supporting legs 111 for the diapire of outer 11 is unsettled setting, both can effectively guarantee outer 11 support intensity, can avoid the holding surface that supports the paper tank again and outer 11 diapire direct contact, thereby further promote the effect that separates the temperature of paper tank.

Preferably, in order to further improve the supporting strength and the heat insulation effect of the tank body 1, the first empty area 12 and the second empty area 13 are filled with the paper honeycomb porous structure body 3.

In another preferred embodiment of the thermal insulation paper tank of the present invention, the thermal insulation paper tank further comprises a cover body 2 covering the tank body 1, the inner layer 10 of the tank body 1 protrudes upwards from the outer layer 11 to form a connecting section 101, the cover body 2 is connected with the tank body 1 by the connecting section 101 in a buckling manner, and a third empty area 14 for space isolation is formed between the cover body 2 and the connecting section 101. In this embodiment, also have space isolation structure between the lid 2 and the jar body 1 to the effect of insulating temperature of paper jar has been guaranteed comprehensively. Preferably, the length of the connecting section 101 occupies 1/3-1/5 of the height of the outer layer 11.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, therefore, the present invention is not limited by the appended claims.
