Description

Technical Field

[0001] This utility model relates to the field of cosmetic technology, and in particular to a cosmetic bottle cap. Background Technology

[0002] Most cosmetic bottle caps on the market use a sealing needle that works with a sealing hole to create a seal. However, most cosmetic bottle caps are made of PP flexible plastic injection molding. This type of injection molded product has a problem: it is prone to shrinkage, which can cause a mismatch between the sealing needle and the sealing hole, resulting in leakage from the sealing hole. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a cosmetic bottle cap.

[0004] This application provides a cosmetic bottle cap, comprising:

[0005] The cover includes a top wall and a peripheral side wall extending downward from the edge of the top wall. A guide column extends upward from the surface of the top wall away from the peripheral side wall, and the guide column communicates with the interior of the peripheral side wall.

[0006] The flip cover includes a connecting frame and a cover portion fixed on the connecting frame. The cover portion has an open receiving cavity. The receiving cavity is provided with a sealing ring extending from the bottom of the cavity toward the open direction. One end of the connecting frame is rotatably connected to the top wall so that the connecting frame can drive the cover portion to move closer to or away from the guide column.

[0007] When the cover is closed by the flip cover, the guide column extends into the receiving cavity, and the sealing ring is engaged with the guide column.

[0008] In one possible implementation, the cosmetic bottle cap further includes:

[0009] A connecting portion extends obliquely upward away from the top wall, one end of the connecting portion is connected to the surface of the top wall opposite to the peripheral side wall, and one end of the connecting frame is rotatably connected to the connecting portion.

[0010] In one possible implementation, the end of the connecting frame that is connected to the connecting part has a clearance opening, the two inner walls of the clearance opening are connected to a rotating shaft, and the two sides of the connecting part have mounting holes that are adapted to the rotating shaft.

[0011] In one possible implementation, the end of the connecting frame away from the connecting portion is bent downward to form an abutment portion, and the surface of the peripheral sidewall is provided with an elastic limiting block adapted to the abutment portion;

[0012] When the cover is closed by the flip cover, the elastic limiting block engages with the abutment portion to lock the connecting frame.

[0013] In one possible implementation, the end face of the guide column away from the top wall is inclined.

[0014] In one possible implementation, the length of the sealing ring is 1 / 2 to 2 / 3 of the length of the guide column.

[0015] In one possible implementation, the inner circumferential surface of the peripheral sidewall is provided with an internal thread for threaded connection with the bottle neck.

[0016] In one possible implementation, the surface of the top wall that is connected to the peripheral side wall is provided with a limiting ring, which is used to limit the bottle opening.

[0017] The technical solutions provided in this application have the following advantages compared with the prior art:

[0018] The flip cap includes a connecting frame and a cap portion fixed to the connecting frame. The cap portion has a receiving cavity for accommodating the guide column, and one end of the connecting frame is rotatably connected to the top wall so that the connecting frame can move the cap portion closer to or away from the guide column. When it is necessary to cap the bottle opening, the connecting frame is pulled towards the top wall so that the guide column extends into the receiving cavity. At this time, the sealing ring located in the receiving cavity extends into the guide column to block the guide column, thereby preventing the liquid in the bottle from flowing out from the port of the guide column, thus providing good sealing performance. If it is necessary to pour out the liquid in the bottle, simply lift the connecting frame away from the top wall so that the sealing ring is pulled out from the guide column, and the cap portion is released from blocking the guide column. At this time, the guide column is in an open state, allowing the liquid in the bottle to be poured out through the guide column for use. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0028] like Figures 1 to 4As shown in the figure, a cosmetic bottle cap according to an embodiment of the present invention includes a cap body 10 and a flip cap 20. The cap body 10 includes a top wall 11 and a peripheral side wall 12 extending downward from the edge of the top wall 11. A guide column 30 extends upward from the surface of the top wall 11 away from the peripheral side wall 12, and the guide column 30 communicates with the interior of the peripheral side wall 12. The flip cap 20 includes a connecting frame 21 and a closing part 22 fixed on the connecting frame 21. The closing part 22 has an open receiving cavity 22a, and a sealing ring 40 extending from the bottom of the cavity towards the open direction is provided in the receiving cavity 22a. One end of the connecting frame 21 is rotatably connected to the top wall 11 so that the connecting frame 21 can drive the closing part 22 to move closer to or away from the guide column 30. Wherein, when the cap body 10 is in the state of being closed by the flip cap 20, the guide column 30 extends into the receiving cavity 22a, and the sealing ring 40 is engaged in the guide column 30.

[0029] It should be noted that the top wall 11 and the peripheral sidewalls 12 can be either a single piece or separate parts. That is, the top wall 11 and the peripheral sidewalls 12 can be manufactured using a single molding process, or they can form two separate structures, i.e., the top wall 11 and the peripheral sidewalls 12 are molded separately and then connected to form the cover 10. Specifically, in this embodiment, the cover 10 is formed using a single injection molding process, making the top wall 11 and the peripheral sidewalls 12 a single piece. This eliminates the need for a connection between the top wall 11 and the peripheral sidewalls 12, thereby ensuring the structural strength of the cover 10.

[0030] Similarly, the flip cover 20 includes a connecting frame 21 and a closing part 22. The connection between the connecting frame 21 and the closing part 22 is also made by an integral molding process, so that the flip cover 20 has strong structural strength and can prevent it from falling off after being opened or closed multiple times.

[0031] In this embodiment, the cosmetic bottle cap, the flip cap 20, includes a connecting frame 21 and a capping portion 22 fixed to the connecting frame 21. The capping portion 22 has a receiving cavity 22a for accommodating the guide column 30. One end of the connecting frame 21 is rotatably connected to the top wall 11 so that the connecting frame 21 can move the capping portion 22 closer to or away from the guide column 30. When it is necessary to close the bottle opening, the connecting frame 21 is pulled towards the top wall 11 so that the guide column 30 extends into the receiving cavity 22a. At this time, the guide column 30 is located in the receiving cavity 22a. The sealing ring 40 inside cavity 22a extends into the guide column 30 to seal it, preventing liquid from flowing out of the guide column 30 and thus providing excellent sealing performance. To empty the liquid, simply lift the connecting bracket 21 away from the top wall 11, pulling the sealing ring 40 out of the guide column 30 and disengaging the cap 22 from its seal. The guide column 30 is then open, allowing the liquid to be poured out. In other words, this cosmetic bottle cap cleverly utilizes the rotating connection of the connecting bracket 21 relative to the top wall 11 to allow the cap 22 to close the guide column 30. Combined with the sealing ring 40 extending into the guide column 30 within the receiving cavity 22a, this seal effectively prevents leakage and provides excellent sealing performance.

[0032] In one possible implementation, the cosmetic bottle cap further includes a connecting portion 70, which extends obliquely upward away from the top wall 11. One end of the connecting portion 70 is connected to the surface of the top wall 11 opposite to the peripheral sidewall 12, and one end of the connecting bracket 21 is rotatably connected to the connecting portion 70. That is, in order to enable the connecting bracket 21 to rotate relative to the connecting portion 70, in this embodiment, by extending obliquely upward along the surface of the top wall 11 opposite to the peripheral sidewall 12, and then rotatably connecting one end of the connecting bracket 21 to the connecting portion 70, the connecting bracket 21 can rotate relative to the top wall 11, thereby ensuring that the capping portion 22 can be driven to seal or open the guide column 30.

[0033] Furthermore, the end of the connecting frame 21 that connects to the connecting part 70 has a clearance opening 21a to ensure that no interference occurs during the rotation of the connecting frame 21, thus ensuring that the covering part 22 can be driven to cover the guide column 30. In addition, a rotating shaft 21b is connected to the two inner walls of the clearance opening 21a, and mounting holes 70a that are adapted to the rotating shaft 21b are provided on both sides of the connecting part 70. That is to say, by connecting the rotating shaft 21b to the two inner walls of the clearance opening 21a and providing mounting holes 70a that are adapted to the rotating shaft 21b on both sides of the connecting part 70, the connecting frame 21 can rotate relative to the connecting part 70, resulting in a simple structure and enabling quick assembly and disassembly.

[0034] In one possible implementation, the end of the connecting frame 21 away from the connecting portion 70 is bent downward to form an abutment portion 60, and the surface of the peripheral sidewall 12 is provided with an elastic limiting block 50 adapted to the abutment portion 60. When the cover 10 is closed by the flip cover 20, the elastic limiting block 50 engages with the abutment portion 60 to lock the connecting frame 21. In practical applications, when it is necessary to seal the guide column 30, the connecting frame 21 is pulled towards the top wall 11 until the guide column 30 extends into the receiving cavity 22a and the sealing ring 40 extends into the guide column 30. Then, the elastic limiting portion engages with the abutment portion 60 to lock the connecting frame 21, preventing leakage during carrying or transportation because the connecting frame 21 detaches from the top wall 11, thus leaving the guide column 30 in an open state. In addition, it should be noted that the elastic limiting block 50 is designed to fasten the abutment part 60 when no liquid is needed, so as to prevent it from falling off.

[0035] In order to facilitate the pouring of liquid from the bottle and prevent accidental spillage, in one possible implementation, the end face of the guide column 30 away from the top wall 11 is inclined.

[0036] In one possible implementation, the length of the sealing ring 40 is 1 / 2 to 2 / 3 of the length of the guide column 30. This ensures that the sealing ring 40 is tightly inserted into the guide column 30 for sealing, resulting in good sealing performance.

[0037] In order to enable quick assembly and disassembly of the bottle cap and the bottle body, in one possible embodiment, the inner circumferential surface of the peripheral wall 12 is provided with an internal thread 12a for threaded connection with the bottle mouth.

[0038] In one possible implementation, the surface of the top wall 11 that is connected to the peripheral side wall 12 is provided with a limiting ring 80, which is used to limit the bottle opening.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
