1. Field of the Invention
The present invention relates to a vessel, especially to a vessel to display a changeable advertisement.
2. Description of the Prior Arts
Conventional vessels have patterns printed on outside surfaces to display an advertisement. However, the advertisements cannot be changed. Therefore, the versatility of the vessel is limited.
To overcome the shortcomings, the present invention provides a vessel to display a changeable advertisement to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a vessel to display a changeable advertisement. The vessel has a double walled vessel, an inside wall assembly, a windup motor, an upper wheel, a key and a bottom wheel. The double walled vessel has an inner vessel and an outer sidewall. The inside wall assembly has an inside wall and a base, and the inside wall is mounted rotatably between the inside vessel and outer sidewall of the double walled vessel. The windup motor is attached to the base of the inside wall assembly and has a rotating mechanism, a shaft and a main gear. The upper wheel is attached to outer sidewall of the double walled vessel and has a secondary gear and a threaded neck. The secondary gear is formed on the upper wheel and engages the main gear. The key extends through the upper wheel, is attached to the windup motor and has a thread. The bottom wheel is mounted around the key and has a central threaded hole. When the central threaded hole screws onto the threaded neck on the upper wheel, the inside wall assembly will rotate. When the central threaded hole screws onto the thread on the key, the double walled vessel will rotate.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The inside wall assembly (20) is mounted rotatably in the inner gap (16) of the double walled vessel (10) and has patterns (201), a top, a bottom, an inside wall (22), a base (24) and a connector (26). The inside wall (22) has a top edge and a bottom edge. The base (24) is attached to the bottom edge of the inside wall (22) and has a bottom surface. The connector (26) is attached to the bottom surface of the base (24) and may have multiple fastening holes (261). The fastening holes (261) are formed through the connector (26).
The windup motor (30) is mounted on the inside wall assembly (20) and has a top, a bottom, a rotating mechanism (301), a shaft (31), a main gear (32), multiple optional fastening holes (33), multiple optional fasteners (34), a central hole (35) and an optional sound generator (36). The rotating mechanism (301) is mounted between the top and the bottom of the windup motor (30). The shaft (31) connects rotatably to and winds up the rotating mechanism (301) and protrudes from the bottom of the windup motor (30). The main gear (32) is mounted securely around the shaft (31). The fastening holes (33) are formed in the top of the windup motor (30) and correspond to the fastening holes (261) in the connector (26). The fasteners (34) extend through the through holes in the base (24) and the fastening holes (261) in the connector (26) and screw into the fastening holes (33) in the windup motor (30) to attach the windup motor (30) to the inside wall assembly (20). The central hole (35) is formed in the bottom of the windup motor (30). The sound generator (36) is mounted on the top of the windup motor (30) to generate sound.
The upper wheel (40) is recessed, is attached to the double walled vessel (10) and has a recessed top, a bottom, a central hole, a secondary gear (41), a threaded neck (42) and an optional flange (43). The secondary gear (41) is formed on the recessed top of the upper wheel (40), engages the main gear (32) and has a central hole (411). The threaded neck (42) is formed on the bottom of the upper wheel (40) and has a central hole (421). The flange (43) is formed around the upper wheel (40) and corresponds to and is attached to the shoulder (13) on the outer sidewall (14) of the double walled vessel (10) to attach the upper wheel (40) to the double walled vessel (10).
The key (50) connects to the upper wheel (40) and has a body (51), a longitudinal rod (52) and a transverse rod (53). The body (51) has a proximal end, a distal end, an outer surface, an annular flange (511) and a thread (512). The annular flange (511) is formed around and protrudes radially out from the body (51) near the proximal end. The thread (512) is formed on the outer surface of the body (51) adjacent to and above the annular flange (511). The longitudinal rod (52) is formed on and protrudes from the proximal end of the body (51), extends through the central holes (421, 411) in the threaded neck (42), the upper wheel (40) and the secondary gear (41) and screws into the central hole (35) in the windup motor (30). The transverse rod (52) extends through the body (51).
The bottom wheel (60) is recessed, is mounted around the key (50) and has a top, a recessed bottom and a central threaded hole (61). The central threaded hole (61) is formed through the bottom wheel (60) and is mounted around the longitudinal rod (52).

Because the inside wall (22) has patterns (201) and the double walled vessel (10) is transparent, the patterns (201) will be more attractive no matter whether the inside wall (22) or the double walled vessel (10) is rotated. When the sound generator (36) on the windup motor (30) generates sound, the sound can correspond to the patterns (101, 201) to further enhance the advertisement.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
