If it is caught by 115, the installation of the discharge valve is completed. When the discharge valve is separated, the discharge valve may be rotated in the opposite direction so that the first catching protrusion 522 is in a portion where the first catching jaw 115 is not formed and then removed. In this way, the discharge valve can be easily attached and detached with a simple structure. Thus, the cleaning of the device becomes easier.

The discharge valve is rotatably installed with respect to the adapter main body 100, and the display unit 520 is provided so that the tap of the display unit 520 faces oppositely when the discharge valve is closed and opened. It can be easily recognized whether it is closed.

Due to the discharge valve as described above it is possible to control the amount of air discharged when filling the beverage to control the filling rate and the amount of foam, when drinking the beverage it is possible to adjust the amount of the beverage discharged.

Beverages containing carbonic acid in a supercritical state, such as beer, will cause a lot of foam as the carbonic acid phase changes as the pressure decreases.

Accordingly, when the beverage is filled so that the top of the display unit 520 is rotated so as to be disposed above, the discharge valve is completely opened.

In addition, when filling the beverage is rotated so that the tap of the display unit 520 is disposed at the bottom to completely close the discharge valve is not the beverage is filled, if the discharge valve is adjusted according to the situation inside the container 50 Pressure can be established to control the filling rate and the amount of foam.

The operation of this embodiment having the above-described configuration will be described below.

As shown in FIG. 7, the adapter body 100 is installed at the inlet 52 of the container 50 so that the discharge pipe 500 is inserted into the container 50.

As shown in FIGS. 8 and 9, the nozzle of the beverage supply device is inserted into the elastic part 220 with the bottom 51 of the container 50 facing upward.

The locking jaw 123 is caught by the gripper of the beverage supply device so that the lower injection adapter is fixed to the beverage supply device.

The nozzle is inserted into the elastic part 220 to lift the cover part 210 upward. Due to this, the lower portion of the elastic portion 220 is fixed by the wing portion 230 and the upper portion of the elastic portion 220 is raised up together with the cover portion 210 so that the elastic portion 220 elastic deformation in the vertical direction do. Therefore, the cover part 210 is spaced apart from the upper surface of the bottom surface 124. In this way, the elastic part 220 is extended, and the injection hole 222 is also large. The height of the upper end of the injection hole 222 is higher than the height of the upper surface of the bottom surface 124. Accordingly, the beverage injected through the nozzle is injected into the adapter body 100 through the bottom surface 124, and the beverage injected into the adapter body 100 is transferred to the container 50 through the fluid passage hole 113. Injected into the inlet 52.

When the beverage is filled in the container 50, the discharge valve is adjusted to adjust the amount of air discharged. Through this, the filling speed and the amount of foam can be controlled.

After dispensing the drink, close the discharge valve.

When the drink is finished and the container 50 is tilted and pulled out, the locking jaw 123 is released from the gripper and the nozzle is released from the valve 200. As a result, the elastic part 220 is returned to its original state, and the vertical length of the elastic part 220 is reduced. Therefore, the cover portion 210 is in close contact with the upper surface of the bottom surface 124 by the elastic force of the elastic portion 220 and the pressure of the beverage in the adapter body 100. The gap between the cover 210 and the wing 230 is reduced. As a result, the injection hole 121 is blocked by the cover portion 210. In addition, since the wing portion 230 also receives the elastic force of the elastic portion 220, the beverage is prevented from leaking even if the valve 200 is touched after injecting the beverage.

The container 50 is then inverted so that the bottom 51 faces downward, and then the lower infusion adapter is removed from the inlet 52 and then closed with the packaging cap to deliver to the takeaway customer.

Alternatively, when drinking the beverage through the lower infusion adapter, as shown in Figure 10, the bottom 51 of the container 50 is faced downward, and the valve (with the lower inlet adapter inserted into the inlet 52) Pressure). When the pressure is applied to the valve 200, the cover portion 210 is lowered to open the injection hole 121. In addition, pressure is applied to the inside of the container 50 so that the beverage of the container 50 is discharged through the pipe member 510 when the discharge valve is opened. That is, when gas is injected into the container 50 through the inlet 121, the pressure inside the container 50 is increased, and the beverage is discharged through the pipe member 510 when the discharge valve is opened.

A pressure injection cap (not shown) may be further provided to effectively apply pressure to the valve 200. The pressure injection cap is detachably installed on the adapter body 100. The pressure injection cap includes a third side wall fitted inside the second side wall, a stopper for blocking one side of the third side wall, and a pressure injection part formed in the stopper in the vertical direction. The pressure injector is disposed at the center of the holder 200. The sealing member is disposed between the outer side of the third side wall and the inner side of the second side wall. The pressure injection cap may have a built-in pump function.

The pressure injected into the vessel 50 can be prevented from flowing back by the valve 200 to maintain a constant pressure continuously.

When drinking a beverage it can adjust the amount of the beverage discharged through the discharge valve. This allows the consumer to easily drink the beverage along the cup without lifting the large container 50.

On the other hand, the adapter body 100 has a hole 117 is formed in communication with the flow path formed in the adapter body 100, the vent valve 700 for opening and closing the hole 117 is provided. The vent valve 700 allows the pressure and foam inside the container 50 to be removed in advance, so that the pressure generated by shaking when the container 50 is turned over to remove the lower injection adapter after injecting the beverage. Bubbles can be removed. Thus, bubbles are prevented from overflowing when the lower injection adapter is pulled out.

The hole 117 is disposed between the shaft diameter portion and the enlarged diameter portion 114 of the first side wall 111. The hole 117 communicates with the fluid passage hole 113.

The holes 117 are horizontally arranged in the left and right directions.

Vent valve 700 is installed detachably to the adapter body (100).

The vent valve installation part 116 is formed on the outer circumferential surface of the first side wall 111 to protrude outward. Thus, the vent valve 700 is disposed outside the vessel 50.

The second catching jaw 118 is also spaced apart from each other facing each other. Therefore, after the second locking projection 721 is inserted into the vent valve seating groove 119 through the portion where the second locking projection 118 is not formed, the second locking projection 721 is rotated by rotating the discharge valve. When the second catching jaw 118 is caught, the installation of the vent valve 700 is completed. When the vent valve 700 is removed, the vent valve 700 may be rotated in the opposite direction so that the second catching protrusion 721 is in a portion where the second catching jaw 118 is not formed and then removed. As such, the vent valve 700 may be easily detached with a simple structure. Thus, the cleaning of the device becomes easier.

The vent valve installation part 116 is provided with a locking protrusion seating groove 119a in which the second locking protrusion 721 is seated so as to communicate with the vent valve seating groove 119.

The outer circumferential surface of the head portion 711 is formed with a seating groove for mounting the sealing member.

One end (inner side) end of the valve rod 710 is formed so that the guide protrusion 712 protrudes inward. The guide protrusion 712 is inserted into the hole 117 to guide the valve rod 710 as the valve rod 710 slides. The outer diameter of the guide protrusion 712 is formed smaller than the diameter of the hole 117.

The valve rod 710 is provided with a second vent passage 713 formed in an up and down direction, and a third vent passage 715 communicating with the second vent passage 713 and formed in a left and right direction. The second vent channel 713 is formed to penetrate the third vent channel 715. The second vent passage 713 and the third vent passage 715 communicate with the first vent passage 723 and the hole 117.

The second vent passage 713 and the third vent passage 715 are disposed outside (close to the other side) of the head portion 711.

A sealing member seating groove 714 is formed on the outer circumferential surface of the valve rod 710 to seat a sealing member disposed between the valve rod 710 and the valve seat 720. The sealing member seating groove 714 is disposed between the second vent flow passage 713 and the other end (outside) end of the valve rod 710.

The c ring insertion groove into which the c ring 716 is inserted is formed at the other outer circumferential surface of the valve rod 710. The c ring 716 is caught by a rod engaging jaw 732 formed on the inner wall of the valve handle 730 described below.

On the outer circumferential surface of the valve handle 730, the handle protrusion 731 is formed to protrude upward or downward on the upper and lower sides. The two handle protrusions 731 are formed to have different protruding lengths. Thus, the vent valve 700 can be easily slid inward or outward, and the vent valve 700 can be easily rotated when the vent valve 700 is detached.

The handle protrusion 731 is formed at the inner side (one side) end of the valve handle 730.

In one side of the valve handle 730, a sliding hole 733 into which the valve rod 710 and the polygonal portion 722 of the valve seat 720 is inserted is formed in the left and right directions. The sliding hole 733 is formed in a polygonal shape so as to correspond to the outer shape of the polygonal portion 722. That is, the valve handle 730 slides with respect to the polygonal portion 722 of the valve seat 720.

The other side of the valve handle 730 is formed with a fastening member seating groove 734 on which the fastening member 740 is seated. The fastening member seating groove 734 is formed to communicate with the sliding hole 733. A rod engaging jaw 732 is formed between the fastening member seating groove 734 and the sliding hole 733. The fastening member seating groove 734 is formed in a cylindrical shape, and the fastening member 740 is rotatable with respect to the valve handle 730.

The other end of the valve rod 710 is provided with a fastening member 740 detachably. For example, a thread is formed on the outer peripheral surface of the other end of the valve rod 710, and the fastening member 740 is formed in a nut shape such that the valve rod 710 and the fastening member 740 may be screwed together. The sealing member is disposed between the valve rod 710 and the fastening member 740. The fastening member 740 is in close contact with the rod engaging jaw 732 formed on the inner wall of the valve handle 730, the c ring 716 installed on the valve rod 710, the valve rod 710 is the valve handle 730 To be fixed). As a result, the valve rod 710 is detachable from the valve handle 730.

The fastening member 740 is formed such that the discharge hole 742 through which bubbles or pressure are discharged penetrates in the left and right directions. The discharge hole 742 communicates with the third vent flow path 715 of the valve rod 710.

The outer end of the fastening member 740 is formed with a head. The head protrudes out of the valve handle 730. The head is formed with a tool groove 741 into which a tool can be inserted. In the present embodiment, the tool groove 741 is formed crosswise. In addition, the tool groove 741 is formed to communicate with the discharge hole 742.

When the container 50 is inverted and then the valve handle 730 of the vent valve 700 is pressed inward (toward the container) after the beverage is injected, the valve rod 710 also slides inward with respect to the valve seat 720. . As a result, the head portion 711, which is in close contact with the inner wall of the valve seat 720, is spaced apart from the inner wall of the valve seat 720, and the pressure and the bubble exiting the hole 117 are controlled by the first vent flow path 723. The second vent 713 and the third vent 715 are discharged to the discharge hole 742.

The lower injection adapter is then removed from the container 50.

When injecting the beverage, if the vent valve 700 is pulled out, the valve rod 710 also slides outward with respect to the valve seat 720. Thus, the head portion 711 is in close contact with the inner wall of the valve seat 720. For this reason, when the beverage is injected, the beverage does not flow out through the vent valve 700.

As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art various modifications or variations of the present invention without departing from the spirit and scope of the invention described in the claims below Can be carried out.
