DETAILED DESCRIPTION OF THE INVENTION

[0015] Referring to FIG. 1 to FIG. 3, the present invention provides a supporting base that constitutes part of a drinking container and that is configured to connect with a bowl (not shown), wherein the bowl has an opening and further has an outer periphery circumferentially provided with an annular groove adjacent to the bottom side of the bowl. The supporting base includes a slender connecting portion 1 configured to be held by a user. The connecting portion 1 is provided with a top portion 2 at the top end and a bottom portion 3 at the bottom end.

[0016] As shown in FIG. 1 and FIG. 3, the top portion 2 has an annular sidewall 21 that surrounds a second receiving room 22. The top end of the sidewall 21 has an inner edge provided with a coupling portion 23. The coupling portion 23 extends toward the center of the second receiving room 22, thus forming a flange to couple with the annular groove of the bowl. In this embodiment, the coupling portion 23 forms a continuous and complete annular flange along the inner edge of the top end of the sidewall 21.

[0017] As shown in FIG. 2 and FIG. 3, the bottom portion 3 is flared and is configured to be placed flat on a flat surface. The bottom side of the bottom portion 3 is concavely provided with an upwardly extending first receiving room 31 such that a supporting portion 32 for standing on a flat surface is formed along the periphery of the bottom side. Also, a positioning portion 33 is provided in the first receiving room 31. In this embodiment, the positioning portion 33 forms a continuous and complete annular structure and has a smaller outer diameter than the supporting portion 32. Thus, an engaging space 34 is formed in the first receiving room 31, between the supporting portion 32 and the positioning portion 33. The rim of the opening of the bowl can extend into the engaging space 34 and press against the positioning portion 33 so as to be secured in position.

[0018] Referring to FIG. 4, the foregoing structure is such that once the bottom end of a bowl 4A is inserted into the second receiving room 22 of the top portion 2 of the supporting base, the sidewall 21 holds the bottom end of the bowl 4A in place. Furthermore, the coupling portion 23 of the sidewall 21 is engaged with the annular groove 41A of the bowl 4A to connect the bowl 4A to the top portion 2.

[0019] Meanwhile, the rim of the opening 42B at the top end of another bowl 4B can be inserted into the engaging space 34 in the first receiving room 31 of the bottom portion 3 of the supporting base and press against the positioning portion 33 so that, with the positioning portion 33 and the rim of the opening 42B pressing against each other, the bowl 4B and the bottom portion 3 are secured in position with respect to each other.

[0020] In summary of the above, the top portion 2 and the bottom portion 3 of the supporting base of the present invention are configured to couple with the bottom end of the bowl 4A and the opening of the bowl 4B respectively, forming a securely positioned series-connected structure that facilitates packaging and transportation of the finished products. The series-connected configuration allows plural supporting bases and plural bowls to be packaged in pairs and saves space effectively.

[0021] FIG. 5 and FIG. 6 show the second embodiment of the present invention, which is based on the first embodiment and involves modification of the coupling portion and the positioning portion. In the second embodiment, the coupling portion includes a plurality of segments 231 arranged at intervals in an annular manner along the inner edge of the top end of the sidewall 21, and the positioning portion includes a plurality of segments 331 arranged at intervals in an annular manner in the first receiving room 31. The structure of the second embodiment is such that the segments 231 of the coupling portion can be engaged in the annular groove of a bowl to produce a connecting effect, and that the segments 331 of the positioning portion can press against the rim of the opening of another bowl to produce a positioning effect. Thus, the second embodiment works just as well as the first embodiment.
