based on the structure of the above embodiments 1-5, the inner container comprises a foldable first component 11 which is penetrated up and down and a second component 12 which closes the lower end opening of the first component 11, the outer shell 2 is sleeved on the periphery of the inner container, the first part 11 comprises an expansion part 110 and a lower connecting end 112 positioned at the lower end of the expansion part 110, the telescopic part 110 is extended out of the upper end opening of the housing 2, the lower connection end 112 is in sealing fit with the second component 12, the lower part of the inner container forms a containing cavity, the telescopic part 110 can be at least partially compressed into the containing cavity, a folding part 111 is arranged between the telescopic part 110 and the lower connecting end 112, the folding part 111 is positioned above the opening of the containing cavity, to facilitate the compression of the first member 11, the upper end of the folded portion 111 has a smaller size than the lower end of the folded portion 111.

Further, as shown in fig. 3 or 7, the upper end of the housing 2 is provided with an extension 211 extending inward, and the extension 211 covers the folded portion 111. On one hand, the extension part 211 can shield the folding part 111 for protecting the folding part 111, and on the other hand, the extension part 211 can also shield the gap between the casing 2 and the inner container.

Further, when the first member 11 is stretched, the edge of the extension portion 211 is in close contact with the side wall of the expansion portion 110. By adopting the technical scheme, the shell 2 can completely shield the folding part 111 under the stretching condition or the compression condition, so that the gap between the shell 2 and the inner container can be completely shielded, impurities can be prevented from entering the gap, and the gap between the shell 2 and the inner container can be ensured to be clean.

When the first member 11 is formed in a volcano-cone shape with a small top and a large bottom, and is configured in a three-fold or five-fold multi-fold structure, the overall height can be reduced after compression. However, this folding method has some problems, and due to the limitation of the folding structure, the folding direction of each fold does not act as expected during the folding process, and further the folding process is not smooth, and there is a problem that the folding is difficult with a high probability. Due to the uncertainty of the bending direction, the kettle liner needs to be arranged by hand in an auxiliary mode in the folding process, the folding process is completed, and the use experience of the folding kettle is greatly reduced.

In order to make full use of the space of the receiving chamber, the first member 11 is provided with only one telescopic portion 110 and one folding portion 111. A receiving cavity is formed below the folding part 111, and a folding cavity is formed above the folding part 111, and the height of the receiving cavity is equal to 1/2 of the folding cavity. When the first member 11 is compressed into the receiving cavity, the expansion portion 110 is folded into the receiving cavity to abut against the bottom of the inner container, and then is bent. The folding portion 111 is located above the housing cavity, and the upper end of the rigid housing cavity has a guiding and supporting function for the folding direction.

Further, the diameter of the cavity formed by the telescopic part 110 is the same from top to bottom. In order to facilitate the compression of the telescopic part 110, the diameter of the cavity formed by the telescopic part 110 is increased from top to bottom.

The shell 2 and the extending part 211 are separated parts, and the shell 2 is buckled and connected with the extending part 211.

Through the cooperation of bowl cover 4 and shell 2, restrict the inner bag and accomodate the intracavity, promote user's use and experience.

In a specific implementation mode, one of the cup cover 4 and the shell 2 is provided with a bulge, the other one is provided with an elastic buckling groove matched with the bulge, and the bulge is embedded into the elastic buckling groove. The limiting structure is formed by matching the protrusions and the elastic buckling grooves.

In another embodiment, one of the cup cover 4 and the housing 2 is provided with an elastic bulge, the other one is provided with a fastening groove matched with the elastic bulge, and the elastic bulge is embedded into the fastening groove. The elastic bulge and the buckling groove are matched to form a limiting structure.

Specifically, the elastic bulge is arranged on the cup cover 4, the cup cover 4 comprises an upper cover and a lower cover, a mounting groove is arranged between the upper cover and the lower cover, a through hole is formed in one side, facing the shell 2, of the mounting groove, the elastic bulge comprises a rigid connecting piece and an elastic piece, one end of the elastic piece is abutted to the connecting piece, the other end of the elastic piece is abutted to the groove wall of the mounting groove, and the connecting piece stretches out of the through hole.

In another embodiment, the side surface of the cup cover 4 is in interference fit with the inner side surface of the shell 2.

Specifically, a plurality of bulges are arranged on the side surface of the cup cover at intervals, a groove matched with the bulges is arranged on the inner side surface of the shell, and the bulges are embedded into the groove.

Further, the cup cover 4 completely covers the upper end opening of the shell 2.

Further, the cup comprises an annular supporting piece 13, and the supporting piece 13 is connected with the upper end of the inner container to limit the deformation of the cup mouth of the inner container.
