Description

A self-sealing tray leak-proof straw cover

technical field

The utility model relates to a packaging bottle, in particular to a packaging bottle cap.

Background technique

Beverage packaging bottles in the prior art do not have a leak-proof function. After the bottle cap is opened, the bottle mouth is wide open, the liquid in the bottle is easy to pour, and external impurities are also easy to enter the bottle and pollute the beverage in the bottle.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides an automatic sealing tray leak-proof straw cover which is simple in production and processing and has an automatic sealing function after opening.

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

An automatic sealing tray leak-proof straw cover, comprising 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, the The elastic part is provided with a straw, the upper end of the straw turns inward toward the tube core and extends to the bottom of the straw to form a sealing column, the lower end of the sealing column is closed, and the sealing column is connected to the top of the straw or the suction tube The side wall of the side wall is provided with several closed thin-walled parts, and the area in the thin-walled part forms a tear part, and the tear part is connected with a pull ring. In the natural state, the elastic force of the elastic part makes the sealing column The bottom is tightly attached to the periphery of the water outlet hole to form a seal.

The beneficial effects of the utility model are: the cover body of the utility model is provided with an elastic sealing tray, and the upper end of the straw turns inward toward the tube core and extends to the bottom of the straw to form a sealing column. In the natural state, the elastic force of the elastic part makes the sealing column The bottom of the bottle is close to the water outlet to form a seal, which can effectively prevent the liquid in the bottle from spilling and foreign debris from entering the bottle after the beverage bottle is opened. When drinking, pull or touch the straw to make the straw tilt and seal the bottom of the column. Leaving the water outlet hole, the liquid in the bottle flows out from the space formed by the inner wall of the straw and the outer wall of the sealing column, and you can drink the liquid in the bottle. After the force acting on the straw disappears, the straw resets under the elastic force of the elastic part, and again Forming a seal, simple production and processing, simple and convenient use.

Detailed ways

Referring to Fig. 1 to Fig. 5, an automatic sealing type tray leak-proof straw cover includes a cover body, and an elastic sealing tray 2 is arranged inside the cover body 1, and the sealing tray 2 can be bonded on 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 sealed tray 2 is provided with a water outlet hole 5, the hole wall of the water outlet hole 5 is in the shape of a trumpet that protrudes upwards and has a large top and a small bottom. The top of the cover 1 is provided with an elastic part 3, and the elastic part 3 A suction pipe 4 is provided, and the upper end of the suction pipe 4 turns inward toward the core and extends to the bottom of the suction pipe 4 to form a sealing column 6, the lower end of the sealing column 6 is closed, and the sealing column 6 and the suction pipe 4 The top connection part or the side wall of the straw 4 is provided with a number of closed thin-walled parts 7, and the area inside the thin-walled part 7 forms a tear-off part 8, and the tear-off part 8 is connected with a pull ring 9, and the pull ring is held by hand 9 tearing, the tearing part 8 breaks along the thin-walled part 7 to form a water outlet 11. In this embodiment, the tearing part 8 is located at the top connecting part of the sealing column 6 and the straw 4, and after the tearing part 8 is pulled apart, a connection is formed at the top connecting part of the sealing column 6 and the straw 4 tendon 10.

In the natural state, the elastic force of the elastic part 3 and the pressure in the bottle make the bottom of the sealing column 6 close to the surrounding of the water outlet hole 5 to form a seal, which can effectively prevent the liquid in the bottle from being spilled and leaked after the beverage bottle is opened. External debris enters the bottle. When drinking, pull or touch the straw to make the straw tilt, the bottom of the sealing column leaves the outlet hole, and the liquid in the bottle flows out from the space formed by the inner wall of the straw and the outer wall of the sealing column, and you can drink The liquid in the bottle, after the force acting on the straw disappears, the straw will naturally recover under the elastic force of the elastic part 3 to form a seal again. The production and processing are simple, and the use is simple and convenient.
