[0041] The bottle cap provided in this embodiment can be applied to, but not limited to, bottles containing laundry detergent, and can also be applied to bottles containing other cleaning solutions.

[0042] like Figure 1 - Figure 4 As shown, the bottle cap provided by the utility model comprises: an outer cover 1, a top cover 2, a first restoring member 3 and a locking structure.

[0043] The outer cover 1 is directly connected to the bottle body 4 , and the two can be connected by threaded connection, or the outer cover 1 can be directly integrated with the bottle body 4 .

[0044] like Figure 4As shown, a through hole 11 extending in the up-down direction is arranged on the top surface of the outer cover 1, wherein the top surface of the outer cover 1 is the side facing the bottle mouth of the bottle body 4. When the through hole 11 is opened, the liquid in the bottle body 4 can flow out from the through hole 11.

[0045] like Figure 3 As shown, a sealing plug is provided on the top cover 2, and the sealing plug can be made of rubber material and has a certain flexibility to improve the sealing effect. The sealing plug can include a plug body 23 and a fixing screw 21. A fixing column 22 extending from top to bottom is provided on the top cover 2, and a screw hole is provided on the bottom surface of the fixing column 22. The plug body 23 is placed below the bottom surface of the fixing column 22, and then the fixing screw 21 is used to pass through the plug body 23 and threadedly connected to the screw hole. Alternatively, the plug body 23 can be integrally formed with the top cover 2.

[0046] like Figure 3 and Figure 4 As shown, along the up-down direction, the outer cover top cover 2 can slide between the first position and the second position relative to the outer cover outer cover 1. The maximum movement range of the top cover 2 can be limited by setting a corresponding limit structure between the top cover 2 and the outer cover 1. Specifically, the side wall of the outer cover outer cover 1 is provided with a guide slot 15 extending along the up-down direction; the side wall of the outer cover top cover 2 is provided with a guide protrusion 27 protruding outward, and the outer cover guide protrusion 27 is slidably connected in the outer cover guide slot 15. When the guide protrusion 27 moves to the uppermost end of the guide slot 15, the top cover 2 is in the second position, and when the guide protrusion 27 moves to the lowermost end of the guide slot 15, the top cover 2 is in the first position.

[0047] In the first position of the outer cover, the outer cover sealing plug seals the outer cover through hole 11. In the process of moving from the first position to the second position, the sealing plug gradually moves away from the through hole 11. In the second position of the outer cover, the outer cover sealing plug opens the outer cover through hole 11.

[0048] The first restoring member 3 of the outer cover is arranged between the outer cover 1 and the top cover 2. The first restoring member 3 can be a first spring, so that the outer cover top cover 2 has a tendency to move toward the second position, that is, when the top cover 2 is in the first position and no external force is applied to the bottle cap, the first restoring member 3 applies an upward thrust to the top cover 2.

[0049] like Figure 4As shown, an assembly surface is provided on the outer cover top cover 2, and the length of the assembly surface in the up-down direction is greater than or equal to the distance between the first position and the second position. A locking groove 261 is provided on the outer cover assembly surface, and the outer cover locking structure includes a locking member 5 and a second reset member 6, and the outer cover second reset member 6 is connected between the outer cover locking member 5 and the outer cover 1, so that the outer cover locking member 5 has a tendency to move toward the outer cover assembly surface, so that the locking member 5 is automatically reset after the external force is removed. When the outer cover top cover 2 is in the first state, the outer cover locking member 5 is inserted into the outer cover locking groove 261 to prevent the outer cover top cover 2 from moving in the up-down direction. Along the radial direction of the outer cover outer cover 1, the outer cover locking member 5 is slidably connected with the outer cover outer cover 1, so that the outer cover locking member 5 can leave the outer cover locking groove 261 under the action of external force.

[0050] When the bottle cap is in use, the outer cover 1 can be fixed on the bottle body 4, and then the user can press the locking member 5 to separate the locking member 5 from the locking groove 261. When completely separated, the top cover 2 will move upward to the second position under the drive of the first reset member 3, so that the sealing plug is separated from the through hole 11, and the through hole 11 is connected to the inside of the bottle body 4, so that the liquid inside the bottle body 4 can be discharged. After the liquid is taken out, the user removes the external force applied to the locking member 5. Under the drive of the second reset member 6, the locking member 5 will always abut on the mounting surface. At this time, the user presses down the top cover 2, so that the top cover 2 returns to the first position. At this time, the locking groove 261 is just opposite to the locking member 5. The locking member 5 can enter the locking groove 261 under the drive of the second reset member 6, and the top cover 2 is locked. The sealing plug blocks the through hole 11 again to prevent the liquid from spilling. The opening and closing of the through hole 11 is realized by pressing. Compared with the threaded sealing in the prior art, the unlocking method is simpler and faster.

[0051] like Figure 3 As shown, the top surface of the outer cover 1 is provided with a first guide tube 12 extending from bottom to top, the opening of the first guide tube 12 of the outer cover faces upward, and the through hole 11 of the outer cover is located in the first guide tube 12 of the outer cover; the bottom surface of the outer cover top cover 2 is provided with a second guide tube 25 extending from top to bottom, the opening of the second guide tube 25 of the outer cover faces downward, and the second guide tube 25 of the outer cover is slidably sleeved on the outside of the first guide tube 12 of the outer cover, and the outer diameter of the first guide tube 12 is substantially equal to the inner diameter of the second guide tube 25, thereby forming a sliding seal. The side wall of the second guide tube 25 of the outer cover is provided with a liquid outlet 251 connecting the inside and the outside. When the outer cover top cover 2 is in the first position, the open end surface of the first guide tube 12 of the outer cover abuts against the bottom surface of the second guide tube 25 to form a seal, and the liquid remaining in the first guide tube 12 will not flow out from the liquid outlet 251. When the outer cover top cover 2 is in the second position, the outer cover liquid outlet 251 is higher than the opening end surface of the outer cover first guide tube 12, and the liquid flows out after passing through the through hole 11, the opening of the first guide tube 12 and the liquid outlet 251 in sequence.

[0052] In order to prevent liquid from flowing from the gap between the first flow guide tube 12 and the second flow guide tube 25 into the top surface of the outer cover 1 outside the first flow guide tube 12 , a first sealing ring 121 is provided between the first flow guide tube 12 and the second flow guide tube 25 of the outer cover.

[0053] In order to make the movement of the top cover 2 more stable and avoid deviation from the up and down direction, a first positioning cylinder 13 extending from bottom to top is provided on the top surface of the outer cover 1, and the opening of the first positioning cylinder 13 of the outer cover faces upward; a notch 131 connecting the inside and outside of the first positioning cylinder 13 of the outer cover is provided on the side wall, and the shape and size of the notch can be the same as the lock groove 261. A second positioning cylinder 26 extending from top to bottom is provided on the bottom surface of the outer cover top cover 2, and the opening of the second positioning cylinder 26 of the outer cover faces downward. The second positioning cylinder 26 of the outer cover is slidably sleeved on the inner side of the first positioning cylinder 13 of the outer cover, and the inner and outer walls of the first positioning cylinder 13 and the second positioning cylinder 26 are in close contact. The first reset member 3 of the outer cover is a first spring, which is inserted into the first positioning cylinder 13 of the outer cover, and the first spring will not shake when compressed and extended. The side wall of the second positioning cylinder 26 of the outer cover forms a mounting surface. When the outer cover is in the first state, the outer cover notch 131 is aligned with the outer cover locking groove 261 so that the outer cover locking member 5 can be inserted into the outer cover locking groove 261 through the outer cover notch 131 .

[0054] Specifically, Figure 2 As shown, the outer cover locking member 5 includes a frame body, the shape of the frame body can be roughly rectangular, the outer cover frame body has an escape hole inside, the escape hole can be roughly rectangular, the outer cover first positioning cylinder 13 is located in the outer cover escape hole, and the radial length of the escape hole is greater than the outer diameter of the first positioning cylinder 13, so that the frame body can move radially relative to the first positioning cylinder 13. The outer cover escape hole includes a first edge and a second edge that are relatively arranged, the first edge is located between the first guide cylinder 12 and the first positioning cylinder 13, and the first edge of the outer cover forms a locking edge 51 that is plugged into the locking groove 261. The second edge of the outer cover is provided with a positioning column 52, and the second reset member 6 of the outer cover is a second spring. The second spring of the outer cover is inserted into the outer side of the outer cover positioning column 52, and one end of the second spring of the outer cover abuts against the second edge of the outer cover, and the other end abuts against the outer wall of the first positioning cylinder 13 of the outer cover, and the positioning column 52 plays a stabilizing role on the second spring.

[0055] The outer cover locking structure also includes a button 7, which is separately provided from the frame. The outer cover button 7 is slidably connected to the outer cover 1, and the sliding direction is radial. The end of the outer cover button 7 located on the outer side of the outer cover 1 is a pressing end, and the other end of the outer cover button 7 located on the inner side of the outer cover 1 abuts against the frame. After pressing the button 7 inward, the button 7 pushes the frame to move, so that the locking edge 51 leaves the locking groove 261. Conversely, after the external force is removed, the locking edge 51 abuts against the mounting surface until the locking groove 261 moves to align with the locking edge 51, and the locking edge 51 enters the locking groove 261 to complete the locking.

[0056] like Figure 2 As shown, the top surface of the outer cover 1 is provided with limiting members 14 located on opposite sides of the sliding direction of the outer cover frame. The limiting members 14 are strip-shaped and have buckles thereon for organizing their upward movement. The limiting members 14 limit the frame in all directions so that it can only slide radially relative to the outer cover 1.

[0057] like Figure 3 As shown, a second sealing ring 24 is provided on the bottom surface of the outer cover sealing plug, and the outer cover second sealing ring 24 is used to seal the through hole 11 after abutting against the top surface of the outer cover 1 .

[0058] The bottle provided by the utility model includes the bottle cap. Since the bottle provided by the utility model uses the bottle cap, the bottle provided by the utility model also has the advantages of the bottle cap.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
