An adaptive beverage container sleeve kit, comprising:
- a sleeve for sleeving a beverage container, comprising an outer shell, an inner shell and a sealed vacuum cavity, wherein the inner shell has a first inner wall and a first outer wall, the first inner wall of the inner shell forming a placement cavity for accommodating the beverage container, and the sealed vacuum cavity being located between the outer shell and the inner shell such that the sleeve functions to maintain a temperature;
- the inner shell has a top and a bottom end, the top being provided with a through hole through which the beverage container is put in or taken out;
- a positioning structure, detachably connected to a top of the sleeve and configured to bond the beverage container with different widths, wherein the positioning structure is capable of contacting at least a part of the beverage container such that when the beverage container sleeve kit is inverted, the beverage container does not fall out of the beverage container sleeve kit;
- besides, when the positioning structure is connected to the sleeve and contacts the beverage container, the user is capable of drinking a beverage from the beverage container;
- and
- an adjusting structure, located in the placement cavity, wherein the adjusting structure is arranged along the bottom end of the inner shell and has a bonding portion connected with the bottom end of the inner shell and a contact portion contacting a bottom end of the beverage container, a height between the bonding portion and the contact portion is deformable to adapt to placement of the beverage container with different heights, and the adjusting structure is deformed to adjust a height along a direction from a bottom end toward a top of the placement cavity, a height of the deformation being less than an overall height of the inner shell, and a width of the deformation being less than a width of the inner shell;
- wherein the adjusting structure comprises an elastic member arranged along the direction from the bottom end toward the top of the placement cavity, the elastic member, when subjected to a pressure exerted by the beverage container toward the bottom end of the placement cavity, being capable of providing an elastic force for pushing the beverage container to move toward the top of the placement cavity such that at least a part of the beverage container keeps in contact with the positioning structure;
- wherein the adjusting structure further comprises a cylindrical member arranged along the direction from the bottom end toward the top of the placement cavity, wherein the bonding portion is connected to a bottom end of the cylindrical member, and the contact portion is connected to a top end of the cylindrical member;
- an elastic cavity for accommodating the elastic member is arranged inside the cylindrical member;
- the cylindrical member is deformable in height;
- and when the beverage container is placed in the placement cavity, the cylindrical member and the elastic member are deformed and shortened in height under the pressure of the beverage container, and under the action of the elastic force of the elastic member, the height of the cylindrical member is kept at a position capable of clamping all or part of the beverage container between the positioning structure and the contact portion;
- wherein the cylindrical member is deformable synchronously with the elastic member;
- wherein the cylindrical member is provided as a deformable corrugated tube structure made of a rigid material, or the cylindrical member is made of a flexible deformable material.
