[0006] In the above-mentioned high-sealing plastic bottle, a first slope is arranged on the top of the bottle body, and a second slope is arranged below the bottle cap to fit with the first slope. Both the first slope and the second slope are provided with threads that can cooperate with each other.

[0007] In the above-mentioned highly sealed plastic bottle, a sealing gasket for sealing is arranged on the notch.

[0008] In the above-mentioned high-sealing plastic bottle, the inlet and outlet grooves are arranged as special-shaped grooves which are wide at the upper and lower ends and narrow in the middle.

[0009] In the above-mentioned highly sealed plastic bottle, an elastic element with elastic reset function is arranged between the support platform and the disc.

[0010] Compared with the prior art, the high-sealing plastic bottle of the present invention, after closing the bottle cap, presses the bottle cap downward, and discharges the air in the bottle body during the process of the disc moving downward quickly, thereby increasing the sealing performance and reducing the oxidation of the medicine in the bottle body.

DETAILED DESCRIPTION

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2 As shown, the high-sealing plastic bottle comprises a bottle body 1 and a bottle cap 2. The bottle body 1 is provided with a sliding protrusion 3. A sliding bottle mouth 4 that can slide up and down is provided in the bottle body 1. Grooves 5 for cooperating with the sliding protrusion 3 are provided on both sides of the sliding bottle mouth 4. A disc 6 for discharging air in the bottle body 1 is provided at the lower end of the sliding bottle mouth 4. A hole 7 for pouring out the contents of the bottle body 1 is provided at the center of the disc 6. Inward notches 8 are provided at both ends of the disc 6.

[0016] A support platform 9 for cooperating with the disc 6 is arranged inside the bottle body 1, and matching blocks 10 for cooperating with the notch 8 are arranged at both ends of the support platform 9. A plurality of air holes 11 for ventilation are opened on the support platform 9, and an inlet and outlet groove 12 for objects in the bottle body 1 to enter and exit is opened at the center of the support platform 9.

[0017] To be more specific, a slope 13 is disposed on the top of the bottle body 1, and a slope 2 14 is disposed below the bottle cap 2 to fit therewith. Both the slope 13 and the slope 2 14 are provided with threads 15 that can cooperate with each other.

[0018] To be more specific, a sealing gasket 16 is provided on the groove 8 for sealing.

[0019] To further elaborate, the entry and exit slot 12 is configured as an anisotropic slot that is wide at the upper and lower ends and narrow in the middle.

[0020] To be more specific, an elastic element 17 having an elastic restoring function is disposed between the support platform 9 and the disk 6 .

[0021] When in use, after closing the bottle cap 2, quickly press the bottle cap 2 downward to make the sliding bottle mouth 4 slide downward into the bottle body 1. After the air in the bottle body 1 is quickly expelled by the disc 6, the disc 6 contacts the support platform 9, so that the notch 8 is combined with the matching block 10, thereby fixing the interactive bottle mouth. Finally, the bottle cap 2 is twisted to make the inclined surface 13 fit with the inclined surface 2 14, and tightened through the thread 15. If it needs to be loosened, unscrew the bottle cap 2, and the sliding bottle mouth 4 will be reset through the elastic element 17.

[0022] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0023] Although this article uses more terms such as bottle body 1, bottle cap 2, sliding protrusion 3, sliding bottle mouth 4, channel 5, disc 6, hole 7, notch 8, support platform 9, matching block 10, vent hole 11, inlet and outlet groove 12, inclined plane 1 13, inclined plane 2 14, thread 15, sealing gasket 16, elastic element 17, etc., it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
