[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Figures 1-7 As shown, the rotary-opening bottle cap includes a base cap 1 and an outer cap 2. The base cap 1 has a screw-on column 101 with an inner storage cavity 102. The outer cap 2 is rotatably connected to the screw-on column 101 and together with the screw-on column 101 forms an outer storage cavity 201 that communicates with the inner storage cavity 102. The outer cap 2 has a liquid outlet 202. When the outer cap 2 rotates relative to the screw-on column 101, it moves axially along the screw-on column 101, causing the screw-on column 101 to open and close the liquid outlet 202. This rotary-opening bottle cap is used in conjunction with a soft (pressable and deformable) bottle body.

[0027] When the bottle cap is opened to dispense material, the outer cap 2 rotates and moves upward relative to the rotating pin 101, causing the rotating pin 101 to open the liquid outlet 202. At this time, squeezing the bottle body allows the material inside the bottle to enter the outer storage chamber 201 from the inner storage chamber 102 and then flow out from the liquid outlet 202. When the bottle cap is closed, the outer cap 2 rotates and moves downward relative to the rotating pin 101, causing the rotating pin 101 to close the liquid outlet 202.

[0028] In summary, this embodiment provides a rotary opening and closing bottle cap to solve the problem that existing bottle caps use a flip-top design, where the flip-top and the base shell are connected by a thin strap, which is prone to breakage, leading to separation of the flip-top and the base shell and damage to the bottle cap. The main solution is to configure the rotary opening and closing bottle cap as a base cap 1 and an outer cap 2. The base cap 1 has a screw-on pin 101, and the outer cap 2 is screwed onto the screw-on pin 101 and can move along the screw-on pin 101 to open and close the liquid outlet 202. The rotary opening and closing structure makes the base cap 1 and the outer cap 2 stably assembled and less prone to loosening and damage.

[0029] In this embodiment of the invention, the top post 101 has a top insertion portion 103. The top insertion portion 103 inserts into or disengages from the outlet 202 when the outer cover 2 moves along the top post 101. The outer diameter of the top insertion portion 103 gradually expands in the direction away from the outlet 202. This configuration, by setting the top post 101 to a plug-in type for opening and closing the outlet 202, results in a simple opening and closing structure, convenient implementation, and excellent closing effect. Furthermore, by configuring the top insertion portion 103 with its outer diameter gradually expanding in the direction away from the outlet 202, it facilitates insertion of the top insertion portion 103 into the outlet 202 while simultaneously ensuring good structural strength and resistance to breakage.

[0030] In the embodiment of the utility model, top insert part 103 has communication port 104, outer storage cavity 201 communicates with inner storage cavity 102 through communication port 104, the aperture of communication port 104 expands gradually in the direction away from liquid outlet 202, communication port 104 is several, several communication ports 104 are arranged at intervals in the circumferential direction of screw top column 101. The above-mentioned setting is configured by configuring multiple communication ports 104 on top insert part 103, and the aperture of communication port 104 is configured to expand gradually in the direction away from liquid outlet 202, so that the discharge amount of top insert part 103 is large and the discharge is smooth.

[0031] In the embodiment of the utility model, the part of top insert part 103 that forms communication port 104 accounts for 1 / 3-1 / 2 of top insert part 103. The above-mentioned setting is configured by configuring the part of top insert part 103 that forms communication port 104 to account for 1 / 3-1 / 2 of top insert part 103, so that the discharge amount of top insert part 103 is large and the discharge is smooth.

[0032] In the embodiment of the utility model, screw top column 101 also has outer screw part 105, outer screw part 105 is arranged above and below top insert part 103, top insert part 103 is on the upper side, and outer screw part 105 is on the lower side. Outer screw part 105 is screw-connected with outer cover 2. The above-mentioned setting is configured by screw-connecting outer cover 2 on outer screw part 105, so that outer cover 2 can move axially along screw top column 101 when rotating relative to screw top column 101, and the driving displacement structure is simple and convenient to implement.

[0033] In the embodiment of the utility model, inner storage cavity 102 extends from the bottom of outer screw part 105 to the position where communication port 104 is located. The above-mentioned setting is configured by configuring inner storage cavity 102 to extend from the bottom of outer screw part 105 to the position where communication port 104 is located, so that top insert part 103 has good discharging effect.
