Description

A self-sealing straw

technical field

The utility model relates to a straw.

Background technique

The straw in the prior art is straight through and does not have sealing and leak-proof functions. After the beverage bottle is toppled over, the liquid in the bottle is easy to spill, and air and sundries also easily enter the beverage bottle, polluting the beverage in the bottle.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides a self-sealing straw with leak-proof and sealing functions.

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

A self-sealing straw, comprising a tube body, the inner wall of the tube body is provided with a connecting part and a retaining ring, the tube body between the connecting part and the retaining ring is a bending part, and the connecting part is provided with a second A water outlet, a sealing plug and a sealing sheet are installed in the bending part, an elastic connector is arranged on the top of the sealing sheet, the upper end of the sealing plug is connected with the retaining ring, and the lower end is connected with the elastic connector , the bottom of the sealing piece is close to the connecting portion, the sealing piece is provided with a third water outlet aligned with the first water outlet, the sealing plug is provided with a second water outlet, and the third water outlet It is misaligned with the second water outlet.

The bottom of the sealing plug is provided with a first protrusion corresponding to the third water outlet.

A second protrusion corresponding to the second water outlet is provided on the top of the sealing sheet.

The beneficial effects of the utility model are: a sealing plug and a sealing sheet are installed in the bending part of the straw of the utility model, and the sealing sheet is provided with an elastic connector. In the natural state, the elastic connector pulls the sealing plug to the sealing sheet, and the straw naturally changes. Straight, the bottom of the sealing plug is in close contact with the sealing sheet to form a seal, which can effectively prevent the liquid in the bottle from spilling and air, sundries, etc. The bottom of the bottle is separated from the sealing sheet, and the liquid in the bottle can flow out, which is convenient to use and has sealing and leak-proof functions.

Detailed ways

Referring to Figures 1 to 5, a self-sealing straw includes a tube body, the inner wall of the tube body is provided with a connecting part 1 and a retaining ring 2, and the tube body between the connecting part 1 and the retaining ring 2 is The bending part 3, the connecting part 1 is provided with a first water outlet 7, the sealing plug 4 and the sealing sheet 10 are installed in the bending part 3, and the top of the sealing sheet 10 is provided with an elastic connector 6, so The upper end of the sealing plug 4 is connected to the retaining ring 2 , the lower end is connected to the elastic connecting member 6 , and the bottom of the sealing sheet 10 is close to the connecting portion 1 .

In this embodiment, the upper end of the sealing plug 4 is turned outward to form a stepped surface, and after assembly, the stepped surface of the sealing plug 4 rests on the retaining ring 2 . The upper end of the elastic connector 6 is T-shaped, and the lower end of the sealing sheet is a cylindrical connector. A groove is arranged on the cylindrical connector, and a mounting hole is arranged in the center of the connecting part 1 and the sealing plug 4, and the elastic connection is made by force. The T-shaped end of piece 6 passes through the installation hole of sealing plug 4, so that the groove on the cylindrical connector snaps into the installation hole on connection part 1. During use, after the straw is bent, it acts on the elastic connection The force on the part 6 and the cylindrical connecting part is small, and the elastic connecting part 6 and the cylindrical connecting part will not be pulled out.

Since the straw is generally made of flexible materials, the wall of the straw itself has certain elasticity and flexibility. As shown in FIG. A part with a relatively small wall thickness is provided on the wall of the straw, and the part with a relatively thin wall thickness forms the bending part 3 .

The sealing sheet 10 is provided with a third water outlet 11 aligned with the first water outlet 7, the sealing plug 4 is provided with a second water outlet 5, and the third water outlet 11 and the second water outlet 5 are misaligned set up. In the natural state, the elastic connector 6 pulls the sealing plug 4 towards the sealing sheet 10, the straw becomes straight naturally, and the bottom of the sealing plug 4 is in close contact with the sealing sheet 10 to form a seal, which can effectively prevent the liquid in the bottle from spilling And air, debris, etc. into the bottle. When drinking, pull the straw to make the bending part elastically deform, the bottom of the sealing plug is separated from the sealing sheet 10, the first water outlet = the second water outlet and the third water outlet are connected, and the liquid in the bottle can flow out. Convenient, airtight and leak-proof.

In order to enhance the sealing performance, a first protrusion 8 corresponding to the third water outlet 11 is provided at the bottom of the sealing plug 4 , or a first protrusion 8 corresponding to the second water outlet 5 is provided at the top of the sealing sheet 10 . The corresponding second protrusion 9, or the first protrusion 8 is set at the bottom of the sealing plug 4 at the same time, and the second protrusion 9 is set at the top of the sealing sheet 10. In the natural state, the first protrusion 8 and/or The second protrusion 9 is plugged into the third water outlet 11 and/or the second water outlet 5 to form a seal.

The material of the connecting part 1 is the same as that of the pipe body, and its hardness is relatively hard. If it is in direct contact with the sealing plug 4, its sealing performance must not be very good. After adding the sealing sheet 10, since the sealing sheet 10 is an elastic material that is easily deformed, it will 4 and the connection part 1 can be in close contact, so as to achieve a better sealing effect.

Suction pipe of the present utility model also can be made into bottle cap shape as shown in Figure 7, cork shape etc., directly covers on existing beverage bottle, replaces existing beverage bottle bottle cap.
