[0022] Example:
[0023] This application discloses a perfume dispensing device; please refer to [link / reference]. Figures 1-2 The device includes an outer cover 1, with an outer screw cap 2 positioned opposite each other on the bottom inner wall of the outer cover 1. An inner screw ring 3 is positioned opposite each other on the bottom inner wall of the outer screw cap 2. A first gasket 4 is positioned between the outer screw cap 2 and the inner screw ring 3. A second gasket 5 is positioned on the bottom surface of the first gasket 4. In the main structure of the perfume dispensing device, the outer cover serves as both overall protection and aesthetic decoration. The outer screw cap is cleverly positioned at a relative position on the bottom inner wall of the outer cover, and the two are connected through a specific structure. Specifically, the lower rib of the outer cover precisely engages with the outer screw cap. This engagement method ensures a stable connection between the outer cover and the outer screw cap without affecting subsequent rotation operations. An inner screw ring is further installed at a relative position on the bottom inner wall of the outer screw cap. The inner screw ring and the outer screw cap are fixed together through a unique engagement structure; that is, the groove at the top of the inner screw ring and the lower rib of the outer cover work together to firmly engage the inner screw ring inside the outer screw cap. To ensure a tight seal between the outer cap and the inner screw ring and prevent perfume leakage, a first gasket is placed between them. This gasket fits snugly and effectively blocks perfume penetration. The other end of the inner screw ring is tightly connected to the glass bottle by screwing it in. This threaded connection method is not only easy to operate but also provides a strong connection that can withstand a certain amount of external force without loosening. Similarly, to ensure a tight seal between the inner screw ring and the glass bottle and prevent perfume leakage during transportation or use, a second gasket is provided on the bottom surface of the first gasket. This gasket further enhances the sealing effect, ensuring the purity and safety of the perfume. The outer cover is engaged with the outer cap by a lower rib, and the inner screw ring is secured inside the outer cap by a top groove and the lower rib of the outer cover. The first gasket achieves a seal between the two. The inner screw ring is screwed into the glass bottle and further sealed by the second gasket. This device creates a pressure difference inside the pump chamber by rotating and pressing the outer cap, thereby achieving the absorption and discharge of perfume from the bottle. It has the advantages of compact structure, easy operation, and good sealing performance.
[0024] The bottom of the inner wall of the outer cover 1 has a lower protruding rib that engages with the outer screw cap 2. The outer cover 1 is connected to the outer screw cap 2 via the lower protruding rib. The outer screw cap 2 and the inner screw ring 3 are interlocked. The outer screw cap 2 and the inner screw ring 3 are sealed by a first gasket 4 to prevent leakage and air ingress. The second gasket 5 improves the sealing between the outer cover 1 and the glass bottle interface. The second gasket 5 is circular in shape and made of silicone. The outer cover 1, the outer screw cap 2, and the inner screw ring 3 are manufactured by injection molding. Both the screw cap 2 and the inner threaded ring 3 are injection-molded plastic parts. The outer cover 1, outer screw cap 2, and inner threaded ring 3 are all independently injection molded, facilitating repair and replacement in case of damage. The first gasket 4 and the second gasket 5 are both made of silicone, providing double leak-proof protection between the outer cover 1 and the outer screw cap 2, and between the inner threaded ring 3 and the bottle mouth. The outer screw cap 2 can rotate on the outer wall of the inner threaded ring 3. The outer screw cap 2 and the inner threaded ring 3 can be compressed into the cavity between them. The outer cover, as the external protective structure of the entire device, has a unique lower end rib on its inner wall bottom. This rib design is ingenious, allowing for precise engagement with the outer screw cap, thus firmly connecting the outer cover and the outer screw cap together. This engagement connection method is not only simple in structure but also strong in connection, effectively preventing loosening or detachment between the outer cover and the outer screw cap. The outer screw cap and the inner threaded ring are connected by interlocking. A first gasket, made of silicone, is placed between them, providing good elasticity and sealing performance. The first gasket fits tightly against the contact surface between the outer screw cap and the inner screw ring, effectively preventing perfume leakage and the ingress of outside air, thus ensuring the purity and quality of the perfume. The inner screw ring is screwed tightly to the glass bottle. To improve the seal at the interface, a second gasket is specially designed. The second gasket is also ring-shaped and made of silicone. Silicone has excellent corrosion resistance and sealing properties, ensuring a tight, leak-free connection between the inner screw ring and the glass bottle. Furthermore, the ring shape of the second gasket better conforms to the bottle opening, further improving the sealing effect. In terms of manufacturing process, the outer cover, outer screw cap, and inner screw ring are all made using injection molding. These components are all injection molded plastic parts, produced independently through injection molding. This manufacturing method not only has high production efficiency but also ensures the dimensional accuracy and surface quality of each component. Meanwhile, since each component is an independently injection molded part, it can be easily repaired or replaced if a component is damaged, reducing operating costs. The first and second gaskets are also made of silicone, forming a double leak-proof protection between the outer cover and the outer screw cap, and between the inner screw ring and the glass bottle mouth. This double protection mechanism can more effectively prevent perfume leakage and the ingress of outside air, further improving the sealing and reliability of the device. During use, the outer screw cap can rotate on the outer wall of the inner screw ring.When the outer cap is rotated, the relative movement between the outer cap and the inner screw ring will compress the cavity between them, thereby changing the air pressure inside the cavity.
[0025] The implementation principle of this embodiment is as follows: the lower rib of the outer cover is engaged with the outer screw cap; the inner threaded ring is engaged within the outer screw cap through the top groove and the lower rib, and is sealed by the first gasket; the inner threaded ring is screwed tightly onto the glass bottle by threads, and is sealed by the second gasket; the outer screw cap, when rotated and pressed, creates a pressure difference inside the pump chamber, thereby achieving the extraction and dispensing of perfume from the bottle. When the perfume dispensing device is needed, the user only needs to rotate the outer screw cap and press it. This action creates a pressure difference inside the pump chamber, and under the action of the pressure difference, the perfume in the bottle is smoothly extracted and dispensed, thus realizing the dispensing and use of perfume.
[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
