When the movable body (13) is rotated, the screw groove (131) and the screw thread (141) are interlocked, thereby allowing the movable body (13) to be raised from the base body (14).

[0042] Referring to Fig. 9, a screw thread (141) may be formed to protrude outward from the outer surface of the first side wall (142). The screw thread (141) may include an upper screw thread portion (131a) located on the upper side, a lower screw thread portion (132b) located on the lower side, and a screw thread connection portion (132c) connecting the upper screw thread portion (131a) and the lower screw thread portion (132b).

[0043] The upper thread portion (131a) may be flat. The lower thread portion (132b) may be flat. The thread connection portion (132c) may be curved. The thread connection portion (132c) may have a shape that is part of a circle with a predetermined diameter when cut perpendicular to the ground.

[0044] The upper thread portion (131a) can form a first angle (θ1) with the second side wall (139). The first angle (θ1) can be an obtuse angle. The lower thread portion (132b) can form a second angle (θ2) with the second side wall (139). The second angle (θ2) can be an obtuse angle. The size of the first angle (θ1) can be smaller than the size of the second angle (θ2). The size of the first angle (θ1) can be 100 degrees. The size of the second angle (θ2) can be 110 degrees.

[0045] A space (100) can be formed between the screw thread lower part (132b) and the screw groove lower part (131b), and between the outer surface of the base body (14) and the inner surface of the moving body (13). As the space (100) is formed, the moving body (13) can rotate more smoothly.

[0046] Referring to FIGS. 2, 3 and 6, the container (10) may be supported by a movable body (13). The container (10) may have a concave shape that is recessed downward. A plate (15) may be disposed on the lower side of the container (10) (hereinafter, the plate (15) may also be referred to as a supporter (15)). A ball (11) may be disposed on the upper side of the container (10). The plate (15) may be placed on the movable body (13). The plate (15) may be formed separately from the ball (11). In different embodiments of the present invention, the plate (15) may be formed integrally with the ball (11).

[0047] Referring to FIGS. 2 to 5, a second rib (157) protruding downwardly may be formed on the back surface of the plate (15). The second rib (157) may be inserted between two adjacent first ribs (147). The second rib (157) may guide the first rib (147) in the vertical direction.

[0048] The second rib (157) may be formed by a plurality of second ribs (157). The second rib (157) may be composed of two second ribs (157) facing each other. Each of the two second ribs (157) may include two rib members (157a, 157b) spaced apart from each other. The rib members (157a, 157b) may have a thin plate shape. The second rib (157) may include an auxiliary rib member (157c) having a thin plate shape between each rib member (157a, 157b).

[0049] The second rib (157) can be inserted between two adjacent first ribs (147), and each rib member (157a, 157b) can be adjacent to two adjacent first ribs (147). As the movable body (13) rotates, the plate (15) supported by the movable body (13) may have a tendency to rotate together with the movable body (13) due to the frictional force of the supporting surface, and at this time, one of the rib members (157a, 157b) may come into contact with the first rib (147). When the movable body (13) is rotated in the opposite direction, the other of the rib members (157a, 157b) may come into contact with the first rib (147). Even if the moving body (13) rotates, the rotation of the plate (15) can be restricted by making contact with the first rib (147) of either of the two rib members (157a, 157b).

[0050] Referring to Fig. 6, the plate (15) may be formed with a flange portion (151) extending outwardly at the edge. The flange portion (151) may be positioned above the seat portion (132b) of the movable body (13). The flange portion (151) may contact the seat portion (132b) of the movable body (13), thereby allowing the movable body (13) to support the plate (15). Since the flange portion (151) is simply placed on and connected to the seat portion (132b), even if the movable body (13) rotates, the plate (15) may not rotate together.

[0051] The ball (11) may be formed with a rim (111) extending outwardly from the edge. The rim (111) may be formed parallel to the ground. The rim (111) may be positioned above the support member (132) of the movable body (13). The rim (111) may be positioned above the first support surface (132a) of the support member (132). A user can easily detach the container (10) by holding the rim (111).

[0052] Referring to FIGS. 7 and 8, the central portion of the ball (11) may be formed parallel to the ground. A first hole (114) may be formed in the central portion of the ball (11). The first hole (114) may be connected to a connecting pipe (17) described later.

[0053] The plate (15) can be formed in a shape that is concave downward so as to come into contact with the back surface of the ball (11).

[0054] The plate (15) may be formed with a hollow tubular portion (153) protruding downward at the center. The tubular portion (153) may have a second hole (154) perforated therein. A joint pipe (17) having one end connected to the joint line (55) may be inserted so as to penetrate the second hole (154). The joint pipe (17) may be formed with a wing (171) protruding outward from the outer surface of the joint pipe (17). A socket (19) may be screw-connected to the tubular portion (153). The wing (171) may be located on the back surface of the tubular portion (153) and on the upper side of the socket (19). As the tubular portion (153) and the socket (19) are screw-connected, the joint pipe (17) may be fixed by being compressed between the tubular portion (153) and the socket (19).

[0055] A hollow packing (18) may be inserted into the body (153). The packing (18) may include a cylindrical lower end (182) with a hollow formed therein. The packing (18) may have a cylindrical upper end (181) with a smaller cross-sectional diameter than the lower end (182) and may be formed with a step. The cross-sectional diameter of the hollow formed in the lower end (182) may be a circular shape with a larger diameter than the cross-sectional diameter of the hollow formed in the upper end (181). The hollow formed in the lower end (182) of the packing (18) and the hollow formed in the upper end (181) of the packing (18) may be connected to each other. The upper end (181) of the packing (18) may have an inwardly bent portion (181a) formed inwardly.

[0056] One end of a joint pipe (17) can be inserted into the inside of the packing (18). One end of the joint pipe (17) can be inserted into the hollow of the lower end (182) of the packing (18). The upper end (17a) of the joint pipe can be in contact with the back surface of the inwardly bent portion (181a) of the packing (18). The upper end (181) of the packing can be inserted into the first hole (114) formed in the ball (11). The packing (18) is inserted into the inside of the body (153), one end of the joint pipe (17) is inserted into the inside of the packing (18), and the joint pipe (17) communicates with the first hole (114) formed in the ball (11), so that a beverage contained in the ball (11) can be supplied or drained along the joint line (55) connected to the joint pipe (17).

[0057] The ball (11) may have an annular rib (115) protruding downward from the edge of the first hole (114). The upper end (181) of the packing may be inserted into the inside of the annular rib (115). Since the upper end (181) of the packing is inserted into the inside of the annular rib (115) without any gap, water contained in the ball (11) may not leak out except through the hollow space formed in the packing (18).

[0058] By forming an annular rib (115) on the edge of the first hole (114), the area in contact with the packing (18) is expanded, thereby preventing water from leaking out more effectively.
