The technical scheme that the utility model solves its technical problem adopts is:

A pressure-type tray leak-proof straw cover, including a cover body, an elastic sealing tray is arranged in the cover body, a water outlet hole is arranged in the center of the sealing tray, an elastic part is arranged on the top of the cover body, and the elastic A suction pipe with a closed top is arranged on the top of the suction pipe, and a sealing column is arranged on the top of the suction pipe. The lower end of the sealing column extends into the water outlet hole, and the upper and lower ends of the sealing column are closed. Closed thin-walled part, the area inside the thin-walled part forms a tear-off part, the tear-off part is connected with a pull ring, the lower end side wall of the sealing column is provided with a water inlet, and in the natural state, the sealing column The side wall forms a seal with the side wall of the water outlet hole, and the water inlet is located above the water outlet hole.

The sealing tray is provided with a fixed ring coaxial with the water outlet hole.

The hole wall of the water outlet hole extends upwards, forming a trumpet shape with a big bottom and a small top.

The lower end of the sealing column is provided with a sealing section, the diameter of the sealing section is smaller than the diameter of the sealing column, the sealing section extends into the water outlet hole, and the water inlet is located on the side wall of the sealing section.

The beneficial effects of the utility model are: the cover body of the utility model is provided with an elastic sealing tray, the center of the sealing tray is provided with a water outlet hole, the top of the cover is provided with an elastic part, and the elastic part is provided with a suction pipe with a closed top, and the top of the suction pipe A sealing column is provided, and the lower side wall of the sealing column is provided with a water inlet. In the natural state, the side wall of the sealing column forms a seal with the side wall of the water outlet hole, and the water inlet is located above the water outlet hole, which can effectively prevent the beverage bottle from opening. The liquid in the bottle is poured and foreign debris enters the bottle. When drinking, press the straw down, the lower end of the sealing column moves down, and the water inlet moves to the bottom of the outlet hole, and you can drink the liquid in the bottle. After the pressure of the straw disappears , the elastic effect of the elastic part moves the sealing column upwards, the side wall of the sealing column forms a seal with the side wall of the water outlet hole, and the water inlet returns to the top of the water outlet hole to form a seal again. The production process is simple, and the use is simple and convenient.

Detailed ways

Referring to Fig. 1 to Fig. 5 , a pressure-type tray leak-proof straw cover includes a cover body 1, and an elastic sealing tray 2 is arranged inside the cover body 1, and the sealing tray 2 can be bonded to the inner side of the cover body 1, or can be It is placed inside the cap body 1, and after being assembled to the bottle mouth, the sealing tray 2 is clamped between the end faces of the cap body and the bottle mouth.

The center of the sealing tray 2 is provided with a water outlet hole 5 , and the wall of the water outlet hole 5 extends upwards, forming a trumpet shape with the lower part larger and the upper part smaller. The top of the cover 1 is provided with an elastic part 3, the elastic part 3 is provided with a suction pipe 4 with a closed top, and the top of the suction pipe 4 is provided with a sealing column 6, and the lower end of the sealing column 6 extends into the water outlet hole 5 Among them, the upper and lower ends of the sealing column 6 are closed, and the upper end surface of the sealing column 6 is provided with a closed thin-walled part 7, and the area inside the thin-walled part 7 forms a tearing part 8, and the tearing A pull ring 9 is connected to the portion 8, and a water inlet 10 is provided on the side wall of the lower end of the sealing column 6. Holding the pull ring 9 and tearing it, the tearing part 8 is broken along the thin-walled part 7 to form a water outlet 13 .

The sealing tray 2 is provided with a fixed ring 11 coaxial with the water outlet hole 5, and the side wall of the sealing column 6 is in contact with the side wall of the fixing ring 11 to play a positioning and fixing role to prevent the sealing column 6 from pressing down. Or when retracting, the sealing column 6 deviates.

The lower end of the sealing column 6 is provided with a sealing section 12, the diameter of the sealing section 12 is smaller than the diameter of the sealing column 6, the sealing section 12 extends into the water outlet hole 5, and the water inlet 10 is located at the The side wall of the sealing section 12, the step surface between the sealing column 6 and the sealing section 12 plays a positioning role to prevent the sealing column 6 from moving down too deep, and the elastic force of the elastic part 3 cannot reset the sealing column 6.

During the natural state, the side wall of the sealing column 6 forms a seal with the side wall of the water outlet hole 5, and the water inlet 10 is located above the water outlet hole 5, and the liquid in the bottle cannot enter the water outlet hole 5, which can effectively Prevent the liquid in the bottle from spilling and foreign debris from entering the bottle after the beverage bottle is opened. The water port flows into the sealing column 6, and then flows out from the water outlet 13. After the pressure of the suction pipe disappears, the elastic action of the elastic part 3 makes the side wall of the sealing column 6 and the side wall of the water outlet hole 5 form a seal, and the water inlet 10 returns. Above the water outlet hole 5, a seal is formed again, the production and processing are simple, and the use is simple and convenient.
