Technical Field

[0001] This utility model relates to the field of plastic cap technology, specifically a leak-proof, high-sealing perfume plastic cap. Background Technology

[0002] There are all kinds of perfumes on the market now, and perfume bottles have become a pursuit for people. The shape, portability and ease of use of perfume bottles have become the trend of people's choices.

[0003] The current perfume bottle cap has a gap between itself and the bottle body during use, which is not a good seal. This allows the liquid inside the bottle to still flow out through the gap, making it very inconvenient to carry the liquid in the bottle. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a leak-proof, highly airtight perfume plastic cap, which solves the problem that existing perfume bottle caps have gaps between them and the bottle body during use, resulting in poor sealing and allowing liquid inside the bottle to still leak out, making it very inconvenient to carry liquid in the bottle.

[0005] To achieve the above, this utility model provides the following technical solution: a leak-proof, high-sealing perfume plastic cap, comprising a main body:

[0006] The main body has an outlet on one side, and a pressing plate is located below the outlet on the side of the main body.

[0007] A knob is provided on the top of the main body;

[0008] The bottom of the main body is provided with a connecting pipe, and the bottom of the connecting pipe is provided with a guide pipe;

[0009] The connecting tube is equipped with a sealing cap, which can effectively seal the bottle and the sealing cap, preventing the perfume from leaking out through the gap between them.

[0010] Optionally, grooves are provided on both the upper and lower sides of the main body. A spring is provided inside the groove, and a wedge is provided at the other end of the spring. The wedge has a trapezoidal cross-section, which can effectively achieve the positioning effect of the baffle, thereby achieving the effect of blocking the flow of perfume and preventing the perfume from flowing out.

[0011] Optionally, a positioning groove is provided on the top of the main body at the position of the knob. There are two positioning grooves, each of which is a semi-circular groove. The two positioning grooves are located on both sides of the knob, which can effectively achieve the positioning effect of the knob, thereby controlling the flow rate of the perfume and avoiding perfume waste.

[0012] Optionally, the bottom of the knob is provided with a sealing post, and positioning posts are embedded on both sides of the bottom of the knob and on both sides of the sealing post. The positioning posts are wider on the inside and narrower on the outside. The positioning posts are adapted to the positioning groove, which can further achieve the positioning effect of the knob, thereby positioning the baffle and enabling the baffle to block or release the perfume.

[0013] Optionally, a threaded groove is provided at the inner opening of the sealing cap, and a sealing gasket is provided inside the threaded groove. The sealing gasket has the same shape as the threaded groove and can be made of rubber or other soft materials, which can effectively achieve a sealing effect between the sealing cap and the bottle opening, preventing perfume from flowing out from the gap between the sealing cap and the bottle opening.

[0014] Optionally, both sides of the sealing cap are provided with buckle plates. The two buckle plates are elastic structures, and the inner side of the two buckle plates is provided with a reinforcing plate. The reinforcing plate is inclined at 30 degrees towards the opening of the sealing cap. Fixing grooves are opened at equal intervals on the inner side of the reinforcing plate, which can effectively increase the firmness between the sealing cap and the bottle body and prevent the sealing cap from detaching.

[0015] Optionally, the main body has a baffle inside, and connecting rods are provided on both the upper and lower sides of the baffle. Limiting grooves are opened on the outer side of the connecting rods. The connecting rods are embedded in the grooves. The wedges are adapted to the limiting grooves, which can effectively achieve the positioning effect of the baffle and prevent the baffle from loosening when blocking the perfume.

[0016] Optionally, the bottom of the knob is provided with a connecting shaft, the bottom of which extends into the interior of the main body and connects to the top of the baffle, which can effectively control the flow rate of the perfume and achieve the effect of blocking or releasing the perfume.

[0017] Compared with the prior art, this utility model provides a leak-proof, highly airtight perfume plastic cap, which has the following beneficial effects:

[0018] This utility model uses a sealing cap, a threaded groove, and a sealing gasket. The sealing cap is connected to the threaded opening of the bottle through the threaded groove. At this time, the sealing gasket is screwed into the thread at the opening of the bottle, so that the sealing cap and the opening of the bottle are tightly connected. The sealing gasket can fill the gap between the two, preventing the perfume from leaking out of the gap.

[0019] This invention utilizes a knob, a connecting shaft, and a baffle. When perfume is needed, the knob is first turned, causing the connecting shaft to rotate. The connecting shaft then rotates the baffle inside the main body. When the knob is turned to the two positioning slots, it is released. At this point, the positioning pin enters the positioning slots to position the knob and simultaneously position the baffle. The perfume then exits through the outlet. When perfume is no longer needed, the knob is turned again, causing the connecting shaft to rotate and the baffle to return to its original position, thus blocking the perfume from flowing out.

[0020] This utility model utilizes a snap-on plate, a reinforcing plate, and a fixing groove. The sealing cap is threadedly connected to the bottle opening via a threaded groove. Since the two snap-on plates are elastic, when the sealing cap is snapped into the bottle opening, the two snap-on plates are engaged below the bottle opening, achieving a stable connection between the sealing cap and the bottle, preventing the sealing cap from detaching. Furthermore, when the two snap-on plates are engaged below the bottle opening, the fixing groove is embedded in the protruding part of the bottle opening, further securing the connection between the sealing cap and the bottle, further preventing the sealing cap from detaching.
