Detailed Description

The present invention is illustrated by the following examples, but the present invention is not limited to these examples. To the embodiment of the present invention, modify or replace some technical features, without departing from the spirit of the present invention, it should be covered in the technical solution scope of the present invention.

As shown in fig. 1 and 2, a plastic bottle cap with a fresh-keeping function comprises a bottle cap base 1 and an upper cap body 2, wherein the upper cap body 2 is hinged to the bottle cap base 1 through a folding part 7, so that a bottle matched with the plastic bottle cap can be conveniently sealed. Wherein, the top edge of the upper cover body 2 is provided with an opening flange 21 for facilitating the operation of a user.

The bottle cap seat 1 is provided with a one-way liquid outlet sealing assembly 3 and a first liquid outlet 4, the one-way liquid outlet sealing assembly 3 means that when a bottle is discharged, the sealing assembly 3 is opened, water in the bottle flows out through the first liquid outlet 4, and after the liquid is discharged, the sealing assembly 3 closes the first liquid outlet 4 to prevent the liquid in the bottle from contacting with outside air and being oxidized, so that the effect of freshness preservation is achieved. Of course, the plastic bottle cap needs to be used with a bottle having two liners to achieve the effect of automatically restoring the original shape of the bottle after being squeezed, and it should be understood by those skilled in the art. The sealing assembly 3 comprises a liquid outlet connecting sheet 30 and a liquid outlet piston 31, the liquid outlet connecting sheet 30 is installed on the top of the bottle cap seat 1 and is arranged above the first liquid outlet 4, and the liquid outlet piston 31 is used for controlling the communication or the separation between the first liquid outlet 4 and the liquid outlet connecting sheet 30. Specifically, the liquid outlet piston 31 includes a blocking portion 310 and a guiding portion 311, the guiding portion 311 is disposed at the bottom of the blocking portion 310, the blocking portion 310 is configured to seal the first liquid outlet 4, the guiding portion 311 is configured to guide the blocking portion 310 to move so as to control the first liquid outlet 4 to be opened or closed, and the bottle cap seat 1 is provided with a mounting hole 50 configured to cooperate with the guiding portion 311. In addition, the sealing component 3 is made of soft rubber, so that the sealing effect is improved.

Further, as shown in fig. 3, the blocking portion 310 is in a frustum shape, the guide portion 311 is in a column shape, a clamping base 3110 is disposed at a bottom end of the guide portion 311, the clamping base 3110 is used for clamping the guide portion 311 in the mounting hole 50, and a diameter of the clamping base 3110 is larger than a diameter of the mounting hole 50.

In this embodiment, the bottle cap seat 1 is provided with a liquid outlet channel 5, and the diameter of the bottom surface of the blocking portion 310 is the same as the diameter of the liquid outlet channel 5, so as to prevent air from entering through the liquid outlet channel 5. The first liquid outlet 4 and the mounting hole 50 are arranged at the bottom of the liquid outlet channel 5, and the liquid outlet channel 5 is communicated with the bottle through the first liquid outlet 4. The liquid outlet piston 31 moves up and down along with the air pressure, so as to open or close the first liquid outlet 4. Specifically, when the liquid is discharged, a user squeezes the bottle, the air pressure in the bottle moves up in the direction of the first liquid outlet 4, and the blocking portion 310 moves up under the guiding action of the guiding portion 311, so that the first liquid outlet 4 is opened, and at this time, the liquid in the bottle flows into the liquid outlet channel 5 through the first liquid outlet 4 and is then sprayed out from the second liquid outlet 6. After liquid discharging is finished, a user loosens extrusion on the bottle, at the moment, outside air is supplemented into the liquid outlet channel 5, the blocking portion 310 is arranged in the liquid outlet channel 5, and the blocking portion 310 moves downwards under the action of air pressure, so that the first liquid outlet 4 is sealed, isolation of liquid in the bottle and outside air is achieved, and the effect of preservation is achieved. Because the bottle is a special bottle with double inner containers, the bottle body at the outer layer can be restored after being extruded to wait for the next extrusion, and the bottle body at the inner layer is always in a contracted state, so that the daily use of the bottle is not influenced.

Further, go out liquid connection piece 30 adaptation lid and close and install go out the top of liquid channel 5 be equipped with second liquid outlet 6 on going out liquid connection piece 30, second liquid outlet 6 with liquid channel 5 is linked together, and the liquid in the bottle is through spout again after second liquid outlet 6 concentrates, prevents that liquid from spraying irregularly.

Preferably, as shown in fig. 4, a distance L1 between the bottom surface of the blocking portion 310 and the top surface of the latch 3110 is greater than a bottom wall thickness L2 of the liquid outlet channel 5, so that the guiding portion 311 can move up and down at the mounting hole 50 to drive the blocking portion 310 to move synchronously, thereby opening or closing the first liquid outlet 4. The moving distance of the guiding portion 311 should not be too large, and is generally 5-10 mm, so as to prevent the blocking portion 310 from failing to seal the first liquid outlet 4.

Further, in order to ensure the liquid outlet amount, in this embodiment, the number of the first liquid outlets 4 is two, and the mounting hole 50 is disposed between the two first liquid outlets 4, so that the liquid outlet speed can be ensured while the liquid outlet amount is ensured.

Furthermore, the inside of the upper cover body 2 is provided with a sealing column 20, the sealing column 20 is used for sealing the second liquid outlet 6, the sealing column 20 extends downwards, when the upper cover body 2 covers the bottle cap seat 1, the sealing column 20 can extend into the liquid outlet channel 5, the sealing effect is enhanced, and the liquid in the bottle is prevented from accidentally flowing out.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
