[0026] The present invention is further described in detail below through the accompanying drawings and specific embodiments.

[0027] The present invention provides a new type of bottle cap and a bottle using the bottle cap. In one embodiment of the present invention, as shown in FIG1 , the bottle comprises a bottle cap 1 and a bottle body 2. Figure 2 , 3 As shown, the bottle cap 1 includes an upper cover 11 composed of a cover body 111 and an outer sleeve 112 clamped on the lower part of the cover body 111, an end cover 12 located on the outer side of the upper cover 11, an upper sheet 13 and a middle sheet 14 located on the inner side below the upper cover 11 and stacked and able to rotate relatively, and a lower sheet 15, and a base 16 located below the lower sheet 15.

[0028] The base 16 includes a plunger 161 with a liquid outlet 16a and a vent hole 16b, a gasket 162 and an inner sleeve 163. Most of the plunger 161 is inserted into the bottle body 2, the top of the plunger 161 protrudes above the bottle mouth and is located on the inner side of the inner sleeve 163, and the gasket 162 is located in the installation groove at the top of the plunger 161.

[0029] Second protrusions 163a are arranged at intervals on the inner side wall of the inner sleeve 163, and second grooves 161a matching the second protrusions 163a are arranged on the outer side wall of the plunger 161. The plunger 161 can be inserted into the inner sleeve 163 during installation, and the second protrusion 163a is provided with a wedge-shaped surface structure to facilitate the insertion of the plunger 161. The lower end of the inner sleeve 163 is provided with a plug-in portion 163b extending downward, and a socket portion 211 corresponding to the plug-in portion 163b is provided on the bottle mouth 21. When the plug-in portion 163b is inserted into the socket portion 211, the rotation of the inner sleeve 163 can be prevented.

[0030] The outer sleeve 112 includes a vertical plate portion 112a extending upward, a clearance groove 111a for accommodating the vertical plate portion 112a is provided on the cover body 111, a hook portion 112b is provided on the top of the vertical plate portion 112a, and a buckle portion 111b matching the hook portion 112b is provided on the cover body 111. When the outer sleeve 112 and the cover body 111 are plugged and fixed, the vertical plate portion 112a enters the clearance groove 111a to enable the two to rotate synchronously.

[0031] The upper cover 11 is buckled onto the base 16 to form a cavity for accommodating the upper sheet 13 , the middle sheet 14 and the lower sheet 15 .

[0032] A first protrusion 163c is provided on the outer side wall of the inner sleeve 163, and a first groove 112c extending along the circumferential direction is provided on the inner side wall of the outer sleeve 112. The first protrusion 163c and the first groove 112c form a rotation anti-slip structure, so that the inner sleeve 163 can rotate relatively in the outer sleeve 112, but prevent it from slipping out. The first protrusion 163c is also provided with a wedge-shaped surface structure to facilitate the inner sleeve 163 to be inserted into the inner side of the outer sleeve 112.

[0033] Slots 163d are provided on the side walls of the inner sleeve 163 and on both sides of the first protrusion 163c and the second protrusion 163a, respectively, so that the side walls can be slightly deformed and give way during insertion to facilitate smooth insertion.

[0034] The upper sheet 13, the middle sheet 14 and the lower sheet 15 are respectively provided with an upper through hole 131, a middle through hole 141 and a lower through hole 151, which can be rotated to be located on the same straight line and above the liquid outlet 16a, so that liquid can be poured out. The upper sheet 13, the middle sheet 14 and the lower sheet 15 are also respectively provided with an upper air hole 132, a middle air hole 142 and a lower air hole 152, which can be rotated to be located on the same straight line and above the air hole 16b.

[0035] A key slot 111c is provided on the inner wall of the cover body 111, and a key 133 protruding radially outward is provided at the edge of the upper sheet 13, so that when the upper sheet 13 enters the inner side of the cover body 111, the key 133 cooperates with the key slot 111c to form a synchronous rotation limiting structure, so that the two can rotate synchronously.

[0036] A first stopper 145 and a first arc groove 134 are provided between the upper sheet 13 and the middle sheet 14, so that the first stopper 145 can be relatively moved in the first arc groove 134 by rotating the upper sheet 13, and when the first stopper 145 is relatively moved to one end of the first arc groove 134, the middle sheet 14 can be driven to rotate together; a second stopper 146 and a second arc groove 154 are provided between the middle sheet 14 and the lower sheet 15, so that the rotation of the middle sheet 14 can make the second stopper 146 relatively move in the second arc groove 154. In this embodiment, the first arc groove 134 is provided on the upper sheet 13, and the second arc groove 154 is provided on the lower sheet 15, and correspondingly, the first stopper 145 and the second stopper 146 are installed in the first mounting hole 143 and the second mounting hole 144 on the middle sheet 14. Of course, in other embodiments, the first arc groove 134 or the second arc groove 154 may also be provided on the middle piece 14 , which will not be described in detail herein.

[0037] The cover body 111 is also provided with a downwardly extending mounting shaft 111 d , and the upper sheet body 13 , the middle sheet body 14 and the lower sheet body 15 are mounted on the mounting shaft 111 d .

[0038] A fixed limiting structure is provided between the base 16 and the lower plate 15 , and the fixed limiting structure is used to prevent the lower plate 15 from rotating. The fixed limiting structure includes a slot portion 153 provided on the lower plate 15 and a column portion 163 e provided on the top of the inner sleeve 163 .

[0039] In this embodiment, the upper sheet 13, the middle sheet 14 and the lower sheet 15 are ceramic sheets, which have the characteristics of simple processing technology and wear resistance, and can achieve a good sealing effect through the upper, middle and lower three-layer structure. Of course, in other embodiments, the middle sheet 14 can also be a flexible or rigid material such as resin, rubber or silicone, but in comparison, the use of ceramic material can also avoid the defects of the above-mentioned other materials that are easy to produce bulging, deformation and the like during use, ensuring that there is always good sealing.

[0040] By adopting the above technical solution, the bottle cap 1 and the bottle of the present invention have good sealing effect, are easy to use and operate, and are relatively simple to assemble. The upper cover 11, the upper sheet 13 and the middle sheet 14 constitute a rotating part, and the lower sheet 15 and the base 16 constitute a fixed part. When sealing is required, the upper cover 11 is rotated to drive the upper sheet 13, so that the upper through hole 131 and the middle through hole 141 are staggered with each other, and the first stopper 145 moves relatively in the first arc groove 134 during rotation. When the first stopper 145 touches the end edge of the first arc groove 134, the middle sheet 14 can be driven to rotate together, so that the middle through hole 141 and the lower through hole 151 are staggered with each other. During the rotation of the middle sheet 14, the second stopper 146 can move relatively in the second arc groove 154 until the second stopper 146 touches the end edge of the second arc groove 154; when opening is required, the upper sheet 13 is rotated in the opposite direction, and finally the middle sheet 14 is driven to rotate until the upper through hole 131, the middle through hole 141 and the lower through hole 151 are located on the same vertical line.

[0041] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
