BACKGROUND OF THE INVENTION
The present invention relates to a large beverage container capable of pouring liquid in a state where it is placed on a table, and more specifically, the liquid is placed on a base placed on the table via a stopper with a cock. The present invention relates to a beverage container in which a pipe to be accommodated is provided upright.
[0002]
[Prior art]
As shown in FIG. 5, the conventional beverage container of the type described above is provided with a pipe 94 for containing a liquid standing on a base 91 placed on a table via a plug 93 with a cock 92. An annular groove 95 is provided along the upper outer peripheral surface of the plug so as not to leak from the connecting portion between the pipe and the plug, and an O-ring 96 is fitted into the groove, so that the groove and the inner peripheral surface of the pipe The O-ring is held in a crushed form.
[0003]
When assembling the beverage container, it is necessary to fit the upper part of the stopper into the lower part of the pipe. At the time of this operation, the O-ring fitted in the state of being positioned in the groove is pushed in a state of being crushed between the pipe and the groove, resulting in a large frictional resistance and making the fitting operation difficult. By the way, since the beverage container is used by replenishing when the liquid runs out, it is necessary to clean the inside for hygiene purposes. However, once assembled, the pipe and the plug are in close contact with the O-ring as described above, so they could not be removed with an ordinary force. For this reason, when cleaning the pipe and plug, A common method is to remove the lid 97 that covers the top of the pipe while it is connected, and insert a cleaning tool such as a sponge with a handle from the top of the pipe to rub off dirt in the pipe. Yes, it was difficult to clean the back (bottom) of the pipe. Further, the inside of the plug body has a complicated shape for guiding the liquid to the cock, and it was practically impossible to clean the inside with a cleaning tool inserted from above the pipe.

【The invention's effect】
When the lower end part of the shielding wall is fitted into the upper part of the plug body, the O-ring located at the upper end part (uppermost position) of the annular groove of the plug body is located above the lower side. Rotating along the taper of the annular groove, which is a deep groove toward the bottom , gradually collapses, so it can be pushed in with a light force compared to the structure of a conventional beverage container, and as a result, assembly work is easy It can be done. Conversely, when removing the plug from the pipe, the O-ring located below the annular groove moves to the upper end while rotating along the taper using its restoring force, so it can be pulled out with a light force. As a result, the disassembly work can be easily performed. In addition, since the assembly and disassembly operations can be easily performed, when the beverage container is cleaned, it can be disassembled and the inside of the lower part of the pipe and the stopper can be washed carefully.
[0019]
Further, since the shielding wall and the upper part of the plug body are formed in corresponding tapered shapes, the O-ring does not touch the inner peripheral surface of the pipe from the lower end of the pipe to the upper position when the shielding wall is fitted into the plug body. Up to this point, the fitting operation can be performed without any frictional force, and as a result, the assembly operation can be performed more easily. Similarly, the disassembling work is further facilitated.
[0020]
In the beverage container according to the second aspect of the present invention, the integration of the stopper and the joint member can be reliably held by the connector.
[0021]
In the beverage container according to the third aspect of the invention, since the upper end of the annular groove is formed one step deeper than the portion below it, the O-ring is connected to the upper position of the annular groove with the same gradient. As a result, the inner peripheral surface is not touched, and as a result, the assembly work can be performed more easily. Similarly, the disassembling work is further facilitated.
