Description

Technical Field

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

[0002] Perfume is a mixture of alcoholic fragrance and a suitable amount of fixative, etc. It has a fragrant and rich aroma. Its main purpose is to be sprayed on clothing, handkerchiefs and hair to emit a pleasant fragrance. It is an important cosmetic. The perfume cap at the mouth of the perfume bottle serves to tighten and prevent the perfume from evaporating and leaking.

[0003] A search revealed Chinese Patent Publication No. CN 210681731 U, published on June 5, 2022, which discloses a leak-proof sealing cap for perfume bottles. The document describes a "cap shell, top cap, annular sealing surface, rotating device, and locking device, wherein the upper end of the cap shell is provided with an integrally molded top cap." When using perfume, the user needs to open the cap to separate it from the spray nozzle, which can easily lead to the cap being lost. In view of this, in-depth research was conducted to address the above problems, resulting in this case. Utility Model Content

[0004] The purpose of this invention is to provide a leak-proof sealing cap for perfume bottles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof sealing cap for perfume bottles, comprising a valve core, a tube body, and a pressing cap. The valve core has an installation groove on its inner side, a sealing gasket on its inner wall, a threaded block on the inner wall of the installation groove, a tube body on its inner side, the upper part of the tube body passing through the valve core and connected to the pressing cap, a nozzle on the left side of the pressing cap, and a rotating device on the outer side of the valve core.

[0006] The rotating device includes a fixed block, a first slide groove and a second slide groove. Fixed blocks are installed on both sides of the outer wall of the valve core. The fixed blocks are located inside the first slide groove. The first slide groove is located inside the fixed cover. A second slide groove is provided on one side above the first slide groove. The second slide groove is located inside the fixed cover. A fixed groove is provided in the middle position above the fixed cover. The pressing cap is located inside the fixed groove.

[0007] Preferably, the valve core and the tube body are integrated, and the tube body and the pressing cap are correspondingly arranged.

[0008] Preferably, the valve core and the mounting groove are integrated, and the valve core is fixedly connected to the threaded block and the fixing block.

[0009] Preferably, the fixing blocks are slidably connected to the first and second sliding grooves.

[0010] Preferably, the fixing cover is integrally formed with the first slide groove and the second slide groove, and the shape of the first slide groove corresponds to the shape of the fixing cover.

[0011] Preferably, the inner wall of the fixing cover and the inner wall of the valve core are tightly fitted together.

[0012] Preferably, the fixing cover and the fixing groove are integrated, and the fixing groove and the pressing cap are correspondingly provided.

[0013] Preferably, the top of the fixing cover is on the same horizontal line as the top of the pressing cap.

[0014] Compared with existing technologies, the beneficial effects of this utility model are:

[0015] By setting a fixed block, a first sliding groove, and a second sliding groove, the user places the tube into the perfume bottle. The tube is then threaded into the bottle opening via a threaded block on the inner side of the mounting groove. A sealing gasket enhances the bottle's seal, preventing perfume leakage. During use, the user rotates the fixed cap in the opposite direction to the threaded block. This rotation causes the fixed cap to rotate, moving the second sliding groove and the fixed block. This causes the fixed block connected to the valve core to slide within the first sliding groove. When the fixed block reaches the connection point between the second sliding groove and the fixed block, the user presses down on the fixed cap, causing it to slide further into the second sliding groove until the bottom of the fixed cap is level with the bottom of the valve core. The pressing cap then slides out of the fixed cap from the inside of the groove, becoming higher than the fixed cap. Pressing the pressing cap, through the valve core, sprays the perfume from the bottle through the tube and out of the nozzle. When not in use, the fixed cap can be reset by reversing the operation, increasing the device's seal and connecting the valve core to the rotating mechanism to prevent loss of the rotating mechanism during use.

[0026] Please see Figure 1-5This utility model provides a technical solution for a leak-proof sealing cap for perfume bottles: A leak-proof sealing cap for perfume bottles includes a valve core 1, a tube body 2, and a pressing cap 3. An installation groove 4 is installed on the inner side of the valve core 1, and a sealing gasket is provided on the inner wall of the valve core 1. A threaded block 5 is installed on the inner wall of the installation groove 4, and a tube body 2 is provided on the inner side of the installation groove 4. The upper part of the tube body 2 passes through the valve core 1 and is connected to the pressing cap 3. A nozzle 7 is provided on the left side of the pressing cap 3, and a rotating device 6 is installed on the outer side of the valve core 1.

[0027] The rotating device 6 includes a fixing block 601, a first slide groove 602 and a second slide groove 603. The fixing blocks 601 are installed on both sides of the outer wall of the valve core 1. The fixing blocks 601 are located inside the first slide groove 602. The first slide groove 602 is located inside the fixing cover 604. The second slide groove 603 is located on one side above the first slide groove 602. The second slide groove 603 is located inside the fixing cover 604. A fixing groove 605 is located in the middle position above the fixing cover 604.

The fixing cap 604 rotates the second slide groove 603 and the fixing block 601, causing the fixing block 601 connected to the valve core 1 to slide inside the first slide groove 602. When the fixing block 601 reaches the connection point between the second slide groove 603 and the fixing block 601, the user presses down on the fixing cap. 604 causes the fixing block 601 to slide inside the second slide groove 603, so that the lower part of the fixing cover 604 is on the same horizontal line as the lower part of the valve core 1, and the pressing cap 3 slides out of the fixing cover 604 from the inside of the fixing groove 605, so that the pressing cap 3 is higher than the fixing cover 604, so that the user can press the pressing cap 3 and, through the action of the valve core 1, spray the perfume inside the perfume bottle through the tube 2 from the nozzle 7 for the user to use. When not in use, the fixing cover 604 can be reset by the above reverse operation to increase the sealing of the device, and at the same time connect the valve core 1 and the rotating device 6 to prevent the rotating device 6 from being lost during use.

[0029] Preferably, the valve core 1 and the tube body 2 are integrated, and the tube body 2 and the press cap 3 are correspondingly arranged.

[0030] Preferably, the valve core 1 and the mounting groove 4 are integrated, and the valve core 1 is fixedly connected to the threaded block 5 and the fixing block 601.

[0031] Preferably, the fixing blocks 601 are slidably connected to the first slide groove 602 and the second slide groove 603.

[0032] Preferably, the fixing cover 604 is integrally formed with the first slide groove 602 and the second slide groove 603, and the shape of the first slide groove 602 corresponds to the shape of the fixing cover 604.

[0033] Preferably, the inner wall of the fixed cover 604 and the inner wall of the valve core 1 are tightly fitted together.

[0034] Preferably, the fixing cover 604 and the fixing groove 605 are integrated, and the fixing groove 605 and the pressing cap 3 are correspondingly set.

[0035] Preferably, the top of the fixing cover 604 is on the same horizontal line as the top of the pressing cap 3.

[0036] Although embodiments of the present utility have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present utility, the scope of which is defined by the appended claims and their equivalents.
