[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] This utility model embodiment provides a leak-proof perfume bottle mouth sealing structure.
[0024] like Figure 1 As shown, the device includes a perfume bottle body 1, with a threaded bottle neck 2 at the upper end. A sealing cap 3 is threaded onto the threaded bottle neck 2. A spray nozzle assembly 4 is installed inside the sealing cap 3. A sealing gasket 5 is installed between the sealing cap 3 and the threaded bottle neck 2. The sealing gasket 5 seals the upper edge of the threaded bottle neck 2 with the side wall of the sealing cap 3, preventing perfume from leaking between the sealing cap 3 and the threaded bottle neck 2. An inner sealing ring 6 is installed between the spray nozzle assembly 4 and the sealing cap 3, forming a seal at the connection between the spray nozzle assembly 4 and the sealing cap 3, preventing perfume from leaking from the installation gap between the spray nozzle assembly 4 and the sealing cap 3.
[0025] like Figure 2 As shown, the top wall of the sealing bottle cap 3 is provided with a limiting protrusion ring 7, and an installation ring groove is provided between the limiting protrusion ring 7 and the side wall of the sealing bottle cap 3. The limiting protrusion ring 7 is inserted downward into the inner wall of the threaded bottle mouth 2. A sealing gasket 5 is sleeved on the outside of the limiting protrusion ring 7. The sealing gasket 5 is placed in the installation ring groove, and the lower side wall of the sealing gasket 5 abuts against the upper edge of the threaded bottle mouth 2. An abutting ring 8 is provided in the installation ring groove, and the abutting ring 8 abuts and presses against the sealing gasket 5.
[0026] like Figure 3 , 4As shown, a deformation groove is provided on the upper side of the sealing gasket 5. A deformation protrusion 9 is provided on the side of the contact ring 8 facing the deformation groove. The cross-section of the deformation protrusion 9 is an inverted trapezoidal shape. When the trapezoidal deformation protrusion 9 is squeezed into the deformation groove, it will cause the two side walls of the deformation groove to deform outward and squeeze between the inner wall of the sealing cap 3 and the outer wall of the limiting protrusion ring 7 to form a seal. A deformation protrusion 10 is provided at the lower end of the deformation protrusion 9. The cross-section of the deformation protrusion 10 is circular. The width of the deformation protrusion is greater than the width of the lower end of the deformation protrusion 9. The deformation protrusion 10 extends into and abuts in the deformation groove, squeezing the lower ends of the two sides of the sealing gasket 5 to deform outward and downward. It can fill the installation gap between the chamfer of the bottle mouth 2 of the threaded bottle mouth 2 and the inner side wall of the sealing cap 3 and the outer wall of the limiting protrusion ring 7 to form a further seal.
[0027] The outer circumferential edge of the contact ring 8 is provided with several positioning slots. An elastic bow piece 11 is disposed within each positioning slot. The front end of the elastic bow piece 11 protrudes from the outer edge of the positioning slot. A snap-fit block is integrally formed at the outer end of the elastic bow piece 11. The outer side wall of the snap-fit block is an inclined surface, and the lower side wall is a horizontal surface. The lower side wall of the snap-fit block 12 snaps into a wedge-shaped groove 13. Several wedge-shaped grooves 13, connected end-to-end, are provided at the top of the inner wall of the sealing cap 3. Each wedge-shaped groove 13 has a triangular groove and includes a lower... The horizontal and inclined sidewalls of the snap-fit block 12 are connected to the horizontal and inclined surfaces of the snap-fit block 13, and the outer edge of the elastic bow piece 11 is snapped into the wedge groove 13. The inclined surface of the snap-fit block 12 is pressed against the inclined surface of the inner wall of the sealed bottle cap 3. The sliding and pressing elastic bow piece 11 retracts and hides in the positioning groove. When it slides to the position of the wedge groove 13, the elastic bow piece 11 resets and squeezes the snap-fit block into the wedge groove 13. The horizontal sidewall of the wedge groove 13 and the horizontal surface of the snap-fit block 12 abut against each other to form a snap-fit, so that the abutment ring 8 can be installed in the sealed bottle cap 3 smoothly.
[0028] like Figure 2As shown, the lower outer wall of the limiting ring 7 is provided with a compression flange 14. The outer diameter of the compression flange 14 is larger than the inner diameter of the threaded bottle mouth 2. The compression ring 15 is engaged with the lower side of the sealing gasket 5 to prevent the sealing gasket 5 from sliding off the limiting ring 7 when the sealing bottle cap 3 is inverted. The lower end of the limiting ring 7 is provided with several deformation grooves 16. The deformation grooves 16 can provide space for the inner wall of the threaded bottle mouth 2 to abut against the compression flange 14 for contraction and deformation. The lower inner wall of the limiting ring 7 is provided with a compression ring 15. The upper side of the compression ring 15 is provided with a compression slope. When the compression flange 14 on the lower side of the limiting ring 7 contracts inward, the compression ring 15 deforms inward and upward accordingly. During this process, the compression slope contracts inward and upward. The nozzle assembly 4 is external A sliding boss 17 is provided on the side, and a sliding inclined surface is provided on the lower side of the sliding boss 17. The sliding inclined surface of the sliding boss 17 slides and abuts against the extrusion inclined surface of the extrusion ring 15. When the extrusion inclined surface contracts inward and upward, it will abut against the sliding inclined surface, so that the sliding boss 17 slides upward on the inner wall of the limiting ring 7. An inner sealing ring gasket 18 is provided on the outer side of the nozzle assembly 4. The outer edge of the inner sealing ring gasket 18 abuts against the inner wall of the limiting ring 7. The sliding boss 17 abuts against the lower side of the inner sealing ring gasket 18. The upward sliding boss 17 will abut against and extrude the inner sealing ring gasket 18, so that the inner sealing ring gasket 18 deforms and expands to both sides, so that a seal is formed between the nozzle assembly 4 and the limiting ring 7 to prevent perfume from leaking from the installation gap between the nozzle assembly 4 and the sealing cap 3.
[0029] Workflow:
[0030] In this invention, the sealing cap 3 is screwed onto the threaded bottle mouth 2 via a threaded connection. During the screwing process, the extrusion flange 14 is squeezed into the threaded bottle mouth 2, and the threaded bottle mouth 2 extends into the mounting ring groove between the limiting protrusion ring 7 and the side wall of the sealing cap 3. During the screwing process, the deformation protrusion 9 and deformation protrusion on the contact ring 8 are squeezed into the deformation groove, causing the two side walls of the deformation groove to deform to both sides respectively, so that a seal is formed between the side wall of the sealing cap 3 and the limiting protrusion ring 7. At the same time, the lower side of the sealing gasket 5 deforms downward and outward under the extrusion of the deformation protrusion, filling the mounting gap between the chamfer of the bottle mouth 2 of the threaded bottle mouth 2 and the inner side wall of the sealing cap 3 and the outer wall of the limiting protrusion ring 7 to form a further seal. This can form a good sealing effect between the threaded bottle mouth 2 and the side wall of the sealing cap 3, preventing perfume from leaking from the side wall of the sealing cap 3.
[0031] Meanwhile, during the process of the extrusion flange 14 of the limiting protrusion ring 7 being squeezed into the threaded bottle neck 2, the lower edge of the limiting protrusion ring 7 can deform inward due to the presence of the deformation groove 16. During the deformation process, the extrusion protrusion ring 15 rotates inward and upward to contract. When the extrusion inclined surface of the extrusion protrusion ring 15 contracts inward and upward, it will abut against the sliding inclined surface, causing the sliding protrusion 17 to slide upward and squeeze the inner sealing ring pad 18, causing the inner sealing ring pad 18 to expand outward and form a seal between the nozzle assembly 4 and the limiting protrusion ring 7, which can prevent perfume from leaking from the gap between the nozzle assembly 4 and the inner wall of the limiting protrusion ring 7.
