Description

Technical Field

[0001] This utility model relates to bottle caps, and more particularly to a rotating double-layer bottle cap for dispensing liquid. Background Technology

[0002] A bottle cap is a sealing component used to close the mouth of a bottle and prevent leakage or contamination of the contents. It is usually used in conjunction with the bottle body (such as glass bottles, plastic bottles, etc.). When it is necessary to obtain the contents of the bottle, the cap must be completely unscrewed from the bottle body, and it is not easy to control the amount of contents poured out. Utility Model Content

[0003] The purpose of this invention is to provide a rotating double-layer bottle cap for dispensing liquid, in order to solve the problem that existing bottle caps are screwed onto the bottle body, and when it is necessary to obtain the contents of the bottle, the entire bottle cap must be screwed off the bottle body, and it is not easy to control the amount of contents poured out.

[0004] This utility model is achieved through the following technical solution:

[0005] A rotating double-layer bottle cap includes an outer cap, an inner cap, and a screw-down cap. The outer cap has a receiving cavity, a connecting port, and a screw ring. The screw ring extends from the connecting port into the receiving cavity for the screw-down cap to be inserted. The inner cap is housed in the receiving cavity and has a dispensing head that can close with the screw-down cap to form a dispensing cavity. The dispensing head has an inner dispensing port that communicates with the dispensing cavity. The screw-down cap has an outer dispensing port that communicates with the dispensing cavity. The outer cap can rotate relative to the inner cap about the axis of the inner cap, causing the screw-down cap and the dispensing head to move relative to each other in the axial direction of the inner cap, so that the inner dispensing port and the outer dispensing port open and close synchronously.

[0006] Furthermore, the outflow port and the inflow port are arranged opposite each other in the axial direction of the inner connecting cover and offset from each other in the radial direction of the inner connecting cover.

[0007] Furthermore, the screw cap is threadedly connected to the screw ring; and / or the screw cap has an assembly hole for inserting the liquid outlet head.

[0008] Furthermore, the inner cover has a limiting groove that extends circumferentially around the inner cover for the insertion of the screw ring and the screw cap.

[0009] Furthermore, the outer peripheral wall of the inner connecting cover is provided with a guide groove extending around its circumference, and the inner peripheral wall of the outer rotating cover is provided with a guide block that slides in cooperation with the guide groove.

[0010] Furthermore, the central angle corresponding to the guide groove is less than 180°; and / or there are two guide grooves, which are arranged opposite to each other on the inner connecting cover.

[0011] Furthermore, the liquid outlet head is provided with a sealing plug on one side of the inner liquid outlet, and the sealing plug is shaped to match the outer liquid outlet for insertion and engagement with the outer liquid outlet.

[0012] Furthermore, there are several internal liquid outlets, which are spaced apart in the circumferential direction of the sealing plug.

[0013] Furthermore, the accommodating cavity opens downwards, the connecting port is located on the top of the outer cap, and a stop ring is provided at the lower end of the cap. When the cap moves upwards to open the inner outlet, the stop ring abuts against the lower end of the screw ring to restrict the movement of the cap.

[0014] Furthermore, the top surface of the outer rotating cover is provided with an indicator mark; and / or the inner peripheral wall of the inner connecting cover is provided with an internal thread.

[0015] The advantage of this technical solution is that by configuring the rotating double-layer bottle cap into an outer screw cap, an inner connecting cap, and a screw-off cap, the inner connecting cap is connected to the bottle body, and the outer screw cap can rotate relative to the inner connecting cap around its axis. This allows the screw-off cap and the dispensing head to move relative to each other along the axis of the inner connecting cap, enabling the inner and outer dispensing ports to open and close synchronously. When it is necessary to obtain the contents of the bottle, simply rotate the outer screw cap to move the screw-off cap away from the dispensing head, allowing the inner and outer dispensing ports to open synchronously and pour out the contents. There is no need to unscrew the entire bottle cap from the bottle body, making the operation convenient. At the same time, since the contents flow from the inner dispensing port into the dispensing chamber and then out through the outer dispensing port, the amount can be effectively controlled, and the operation is accurate.

[0026] 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.

[0027] Example: Figure 1-8 As shown, the rotating double-layer bottle cap includes an outer cap 1, an inner cap 2, and a screw cap 3. The outer cap 1 has a receiving cavity 101, a connecting port 102, and a screw ring 103. The receiving cavity 101 opens downwards, and the connecting port 102 is located at the top of the outer cap 1. The screw ring 103 extends into the receiving cavity 101 from the connecting port 102 for the screw cap 3 to be inserted. The inner cap 2 is housed in the receiving cavity 101 and has a dispensing head 201 that can be closed with the screw cap 3 to form a dispensing cavity 4. The dispensing head 201 has an inner dispensing port 202 that communicates with the dispensing cavity 4. The screw cap 3 has an outer dispensing port 301 that communicates with the dispensing cavity 4. The outer cap 1 can rotate relative to the inner cap 2 around the axis of the inner cap 2, causing the screw cap 3 and the dispensing head 201 to move relative to each other in the axial direction of the inner cap 2, so that the inner dispensing port 202 and the outer dispensing port 301 open and close synchronously. When the screw cap 3 abuts against the top surface of the liquid outlet 201, the screw cap 3 closes the inner liquid outlet 202, and the liquid outlet 201 closes the outer liquid outlet 301. When the screw cap 3 moves away from the top surface of the liquid outlet 201, the screw cap 3 opens the inner liquid outlet 202, and the liquid outlet 201 opens the outer liquid outlet 301.

[0028] When the rotating double-layer cap is used with the bottle body, the inner cap 2 is screwed onto the bottle body. When the user rotates the outer cap 1 counterclockwise, the outer cap 1 causes the screw cap 3 and the dispensing head 201 to move away from each other, causing the inner dispensing port 202 and the outer dispensing port 301 to open simultaneously. The dispensing head 201 and the screw cap 3 then form the dispensing chamber 4. At this time, if the user tilts the bottle to pour out the contents, the contents will flow into the dispensing chamber 4 from the inner dispensing port 202 and then pour out from the outer dispensing port 301. When the user rotates the outer cap 1 clockwise, the outer cap 1 causes the screw cap 3 and the dispensing head 201 to come closer together, causing the inner dispensing port 202 and the outer dispensing port 301 to close simultaneously.

[0029] In summary, this embodiment provides a rotating double-layer bottle cap to solve the problems of existing bottle caps that are screwed onto the bottle body, requiring the entire cap to be screwed off the bottle body to obtain the contents, and making it difficult to control the amount when pouring. The solution is to configure the rotating double-layer bottle cap as an outer screw cap 1, an inner connecting cap 2, and a screw-off cap 3. The inner connecting cap 2 is connected to the bottle body, and the outer screw cap 1 can rotate relative to the inner connecting cap 2 around its axis. The screw-off cap 3 and the dispensing head 201 are aligned axially with the inner connecting cap 2. The relative movement of the upper part causes the inner outlet 202 and the outer outlet 301 to open and close synchronously. When it is necessary to obtain the contents of the bottle, simply rotate the outer cap 1 to move the cap 3 away from the outlet head 201 so that the inner outlet 202 and the outer outlet 301 open synchronously to pour out the contents. There is no need to unscrew the entire cap off the bottle, making the operation convenient. At the same time, since the contents flow from the inner outlet 202 into the outlet chamber 4 and then out from the outer outlet 301, the amount can be effectively controlled and the operation is accurate.

[0030] In this embodiment of the invention, the outgoing liquid outlet 301 and the inner liquid outlet 202 are axially opposite to each other on the inner connecting cover 2 and radially offset from each other. This arrangement, by configuring the outgoing liquid outlet 301 and the inner liquid outlet 202 to be axially opposite to each other on the inner connecting cover 2 and radially offset from each other, allows the inner liquid outlet 202 and the outgoing liquid outlet 301 to open and close simultaneously when the outer rotating cover 1 moves relative to the rotating abutment cover 3 and the liquid outlet head 201.

[0031] In this embodiment of the invention, the screw cap 3 has an assembly hole (not shown in the figure) for inserting the liquid outlet head 201, and the screw cap 3 is threadedly connected to the screw ring 103. This configuration, by threading the screw cap 3 to the screw ring 103, allows the outer cap 1 to rotate, driving the screw cap 3 and the liquid outlet head 201 to move relative to each other axially in the inner cap 2. The drive structure is simple and easy to implement. Simultaneously, by providing the assembly hole for inserting the liquid outlet head 201 on the screw cap 3, the movement of the screw cap 3 is stable and smooth.

[0032] In this embodiment of the invention, the inner cover 2 has a limiting groove 203, which extends circumferentially around the inner cover 2 to accommodate the screw ring 103 and the screw-stop cover 3. This arrangement, by providing the limiting groove 203 on the inner cover 2 for the screw ring 103 and the screw-stop cover 3 to be inserted, ensures stable assembly of the outer cover 1, the inner cover 2, and the screw-stop cover 3, and allows the outer cover 1 to rotate stably and smoothly.

[0033] In this embodiment of the invention, the outer peripheral wall of the inner cover 2 is provided with a guide groove 204 extending circumferentially therearound, and the inner peripheral wall of the outer cover 1 is provided with a guide block 104 that slides with the guide groove 204. This arrangement, by configuring the guide groove 204 on the outer peripheral wall of the inner cover 2 and the guide block 104 on the inner peripheral wall of the outer cover 1, ensures a stable connection and smooth rotation between the outer cover 1 and the inner cover 2.

[0034] In this embodiment of the invention, the central angle corresponding to the guide groove 204 is less than 180°. By configuring the guide groove 204 such that the corresponding central angle is less than 180°, the rotation amplitude is reasonable when the outer cap 1 drives the cap 3 to move relative to the liquid outlet head 201 to open and close the inner liquid outlet 202 and the outer liquid outlet 301, thus simplifying user operation.

[0035] In this embodiment of the invention, there are two guide grooves 204, which are arranged opposite to each other on the inner connecting cover 2. By configuring the guide grooves 204 into two, the outer rotating cover 1 and the inner connecting cover 2 are stably connected and rotate smoothly.

[0036] In this embodiment of the invention, a sealing plug 205 is provided on one side of the inner outlet 202 of the dispensing head 201. The sealing plug 205 is shaped to fit the outer outlet 301 for insertion and engagement. When the cap 3 is screwed against the top surface of the dispensing head 201, the cap 3 closes the inner outlet 202, and the sealing plug 205 is inserted into the outer outlet 301 to close it. When the cap 3 is screwed away from the top surface of the dispensing head 201, the inner outlet 202 opens, and the sealing plug 205 exits the outer outlet 301. This arrangement, by providing the sealing plug 205 on the dispensing head 201, ensures a good closing effect for the outer outlet 301.

[0037] In this embodiment of the utility model, there are several internal liquid outlets 202, which are spaced apart in the circumferential direction of the sealing plug 205.

[0038] In this embodiment of the invention, a stop ring 302 is provided at the lower end of the screw cap 3. When the screw cap 3 moves upward to open the inner liquid outlet 202, the stop ring 302 abuts against the lower end of the screw ring 103 to restrict the movement of the screw cap 3. The above arrangement, by configuring the stop ring 302 at the lower end of the screw cap 3, prevents the screw cap 3 from detaching from the outer screw cap 1 when it moves upward to open the inner liquid outlet 202, thus ensuring structural stability.

[0039] In this embodiment of the invention, an indicator mark 106 is provided on the top surface of the outer rotating cover 1. This arrangement, by providing the indicator mark 106 on the top surface of the outer rotating cover 1, facilitates user operation.

[0040] In this embodiment of the invention, the inner peripheral wall of the inner cap 2 is provided with an internal thread 206. This arrangement, by providing the internal thread 206 on the inner peripheral wall of the inner cap 2, facilitates the connection of the inner cap 2 to the bottle body.
