[0029] The present invention is described in detail below with reference to the accompanying drawings.
[0030] like Figure 1-3 As shown, a non-stick and leak-proof plastic bottle includes a bottle body 1 and a bottle cap 2 installed on the top of the bottle body 1. The top of the bottle body 1 is formed with a bottle mouth 11. The cross-sectional shape of the upper half of the bottle mouth 11 is circular, and the cross-sectional shape of the lower half of the bottle mouth 11 is rectangular. The area of the rectangle is smaller than that of the circle; the bottle cap 2 includes a cover body 21 and a first ring sleeve 3 coaxially formed at the bottom of the cover body 21. The first ring sleeve 3 cooperates with the bottle mouth 11. A sealing column 22 inserted into the bottle mouth 11 is formed in the first ring sleeve 3. A rectangular block 23 that cooperates with the bottle mouth 11 with a rectangular cross-section is formed at the bottom of the sealing column 22. A second ring sleeve 31 is slidably installed on the first ring sleeve 3. The second ring sleeve 31 is installed with a locking threaded rod 33 that can move longitudinally and a bolt movable hole 37 for axial movement of the locking threaded rod 33. The bottle body 1 is formed with a mounting plate 12 located at the bottom of the bottle mouth 11. The mounting plate 12 is formed with a locking threaded hole 14 that cooperates with the locking threaded rod 33.
[0031] When the bottle cap 2 is matched with the bottle mouth 11, the sealing column 22 of the bottle cap 2 is first inserted into the bottle mouth 11, and the rectangular block 23 at the bottom of the sealing column 22 is embedded in the rectangular area of the bottle mouth 11. At this time, the bottle cap 2 will not rotate; then the first ring sleeve 3 surrounds the bottle mouth 11, and the second ring sleeve 31 slides along the first ring sleeve 3, so that the locking threaded rod 33 is inserted into the locking threaded hole 14 of the mounting plate 12 to achieve locking; this can prevent the bottle cap 2 and the bottle mouth 11 from detaching, prevent the liquid in the bottle body 1 from leaking, and improve the sealing performance.
[0032] The rectangular block 23 is formed from a deformable rubber material. The cross-sectional area of the rectangular block 23 is slightly larger than the rectangular cross-sectional area of the bottle mouth 11. Therefore, after the rectangular block 23 enters the rectangular area of the bottle mouth 11, it can fit with the inner wall of the bottle mouth 11, which can further improve the stability of the seal.
[0033] Specifically, a sealing connection structure is provided between the sidewall of the rectangular block 23 and the inner wall of the bottle mouth 11. This sealing connection structure includes a first outer ring groove 24 and a second outer ring groove 25 formed in the outer wall of the rectangular block 23. Each of the first and second outer ring grooves 24, 25 is fitted with a sealing strip 26. Once the rectangular block 23 enters the rectangular area of the bottle mouth 11, the sealing strips 26 located in the first and second outer ring grooves 24, 25 adhere to the inner wall of the bottle mouth 11, further improving the sealing stability and reducing the possibility of leakage.
[0034] A sealing groove 15 is formed in the rectangular cross-sectional area of the lower half of the bottle mouth 11, which is radially aligned with the sealing strip 26; after the rectangular block 23 enters the rectangular area of the bottle mouth 11, the sealing strip 26 located in the first outer ring groove 24 and the second outer ring groove 25 will radially fit with the sealing groove 15 of the bottle mouth 11, further improving the stability of the seal and reducing the probability of leakage.
[0035] The gap between the first ring sleeve 3 and the sealing column 22 is provided with an annular sealing sleeve 32, and the annular sealing sleeve 32 is installed at the top of the gap between the first ring sleeve 3 and the sealing column 22; the outer ring wall of the bottle mouth 11 is formed with a sealing outer ring groove 16, and the sealing outer ring groove 16 is installed with an outer ring sealing sleeve 17 that cooperates with the inner wall of the first ring sleeve 3. In this embodiment, when the bottle cap 2 is matched with the bottle mouth 11, the first ring sleeve 3 will surround the bottle mouth 11. At this time, the bottom of the annular sealing sleeve 32 is in contact with the top of the bottle mouth 11, and the outer ring sealing sleeve 17 is in contact with the outer wall of the bottle mouth 11 and the inner wall of the first ring sleeve 3, which is double waterproof and can further prevent liquid from overflowing from the bottle mouth 11.
[0036] A serrated block 13 is formed on the top of the mounting disk 12, and a serrated groove 36 is formed on the bottom of the second ring sleeve 31 to be engaged with the serrated block 13; the second ring sleeve 31 slides along the first ring sleeve 3, so that the locking threaded rod 33 is inserted into the locking threaded hole 14 of the mounting disk 12 to achieve locking; it can prevent the bottle cap 2 and the bottle mouth 11 from separating, prevent the liquid in the bottle body 1 from leaking, and improve the sealing performance; at the same time, the second ring sleeve 31 will cooperate with the serrated block 13 of the mounting disk 12 through the serrated groove 36, further preventing the second ring sleeve 31 from rotating loose.
[0037] Preferably, a guide groove 34 is formed axially on the inner wall of the second ring sleeve 31, and a guide sliding block 35 is formed at the bottom of the first ring sleeve 3 to slide with the guide groove 34. When the second ring sleeve 31 slides, it slides with the guide sliding block 35 through the guide groove 34 to improve the sliding stability.
[0038] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.
[0039] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
