Description

Technical Field

[0001] The utility model belongs to the technical field of paper bowls, in particular to a food packaging paper bowl which can be conveniently heated. Background Art

[0002] A paper bowl refers to a paper container that is made by mechanically processing and gluing base paper (white cardboard) made from chemical wood pulp. It has a bowl-shaped appearance and is mostly used for food delivery packaging.

[0003] After searching, the utility model with announcement number CN218791645U discloses a disposable insulated paper bowl, including a bowl body, an upper sealed end, a sealing cover and a base. The base is embedded and installed in the middle position of the bottom of the bowl body, and the upper sealed end is embedded and installed in the top edge position of the bowl body. This disposable insulated paper bowl adopts an inner and outer double-layer structure, which greatly improves the overall structural strength and thermal insulation capacity, and has stronger thermal insulation performance when holding hot food. At the same time, the inner and outer double-layer structure is matched with multiple sets of support beams for connection to improve the overall compressive resistance and avoid deformation due to external force. The base frame can hold a heating pack, and the heat can be dissipated between the outer bowl and the inner bowl to effectively keep the food warm.

[0004] The paper bowl also has the following disadvantages during use: when in use, the heat of the heating pack is used to heat the inner bowl. If the heating needs to be stopped during the heating process, the heating pack needs to be taken out from the bottom, which is not only inconvenient to use, but also improper operation may cause the food inside to spill. In addition, when the heating pack is used for heating, the inner bowl is easily heated unevenly. Therefore, a food packaging paper bowl that can be conveniently heated is proposed. Utility Model Content

In the above technical scheme, the lifting mechanism can drive the water bag 6 to shrink and expand. When the water bag 6 expands, the liquid in the water pipe 4 can be sucked into the water bag 6, reducing the contact area between the liquid and the inner bowl 3, thereby isolating the heat of the liquid. On the contrary, the water bag 6 shrinks and flushes the liquid into the water pipe 4, increasing the contact area between the liquid and the inner bowl 3 to facilitate heating of food.

[0033] In other aspects of this embodiment, Figure 2 and Figure 3 As shown, the lifting mechanism includes a limit strip 5 fixedly arranged around the inner wall of the outer sleeve 1, the limit strip 5 corresponds to the water pipe 4, the inner wall of the base 2 is fixedly connected with a connecting tube 7, the top of the connecting tube 7 is slidably provided with a sliding column 8, and the sliding column 8 is fixedly connected to the bottom of the inner bowl 3. In the above technical solution, rotating the outer sleeve 1 can drive the inner bowl 3 to rise through the water pipe 4 and the limit strip 5, so that the inner bowl 3 is away from the outer sleeve 1, thereby driving the water bag 6 to shrink and expand.

[0034] In other aspects of this embodiment, Figure 2 As shown, a flange 14 is provided on the top of the inner bowl 3. In the above technical solution, the setting of the flange 14 can not only position the inner bowl 3 when it is lowered, but also facilitate use.
