Description

Technical Field

[0001] The invention relates to the technical field related to aerosols, and in particular to an anti-theft and anti-dust aerosol actuator. Background Art

[0002] The aerosol actuator is an important part of the aerosol can. By pressing the aerosol actuator on the top of the aerosol can, the product packaged in the aerosol can is sprayed out in the form of mist.

[0003] Currently, aerosol cans on the market are all provided with an outer cover to protect the aerosol actuator, and the outer cover is directly mounted on the upper end of the aerosol can. In this case, when the aerosol can is sold publicly, the outer cover can be easily removed and replaced, or used in advance before being sold, and the seller and the consumer cannot directly judge from the appearance whether the outer cover of the aerosol can has been replaced or used in advance.

[0004] In addition, many users tend to lose the outer cover after using the aerosol can, or choose not to replace the outer cover for ease of use next time. Therefore, when the aerosol can is stored later, the aerosol actuator is not protected by the outer cover, and the nozzle is directly in contact with the outside world. Dust in the outside world can easily enter the actuator through the nozzle, thereby contaminating the contents of the aerosol can that are subsequently sprayed out through the nozzle.

[0005] The present invention is made based on this situation. Summary of the invention

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an anti-theft and anti-dust aerosol actuator having the characteristics of significant anti-theft performance and excellent dust-proof effect.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 3 As shown, the present invention proposes an anti-theft and dust-proof aerosol actuator, an anti-theft and dust-proof aerosol actuator, comprising an actuator body 2 that can be fixedly connected to a container 1, a push head 21 is provided on the actuator body 2, a spray head 22 is provided on the push head 21, a nozzle 23 is provided on the spray head 22, a dust cover 3 that can cover the nozzle 23 is movably connected to the spray head 22, an outer cover 4 is connected to the actuator body 2, the outer cover 4 comprises an upper cover 41 and an anti-theft base 43 connected to the upper cover 41 through a plurality of connecting ribs 42, after the upper cover 41 is screwed to break the connecting ribs 42, the upper cover 41 is separated from the anti-theft base 43.

[0029] like Figure 2 , Figure 3 and Figure 6 As shown, the actuator body 2 is fixedly connected to the anti-theft base 43 by a snap connection, and a stop tooth portion 24 is provided in a ring shape on the lower end surface of the actuator body 2. The inner wall of the anti-theft base 43 is provided with a plurality of stop protrusions 431 corresponding to the stop tooth portion 24. The stop tooth portion 24 and the stop protrusion 431 cooperate to limit the rotation of the anti-theft base 43 relative to the actuator body 2, making it easy to screw on the upper cover 41.

[0030] like Figure 3 and Figure 7 As shown, a groove 432 is provided in an annular manner on the inner wall of the anti-theft base 43, and a convex edge 25 is provided along the circumference of the outer peripheral surface of the actuator body 2 located below the anti-rotation tooth portion 24. The convex edge 25 is clamped in the groove 432, so that the anti-theft base 43 and the actuator body 2 achieve an interference fit, thereby ensuring the stability of the fixed connection between the two and avoiding premature opening of the aerosol can by directly removing the anti-theft base 43.

[0031] When the aerosol can is used for the first time, since the anti-theft base 43 is restricted by the actuator body 2 and cannot be separated from the actuator body 2, it is necessary to screw the upper cover 41 to break the connecting rib 42, thereby separating the upper cover 41 from the anti-theft base 43. After removing the upper cover 41 separated from the anti-theft base 43 from the actuator body 2, the dust cover 3 can be opened to use the aerosol can normally. The breaking of the connecting rib 42 will form an irreversible anti-theft mark, so that sellers and consumers can directly determine whether the product has been illegally opened or replaced by observing the integrity of the external connecting rib 42 of the aerosol can product, effectively preventing the aerosol can product from being used in advance before it is sold or the outer cover 4 from being maliciously replaced.

[0032] like Figures 3 to 7 As shown, an annular step 26 is provided on the outer side of the actuator body 2, and an outwardly protruding first buckle line 27 is provided on the outer peripheral surface of the actuator body 2 above the step 26, and a second buckle line 411 matching the first buckle line 27 is provided along the inner circumferential wall of the upper cover 41. After the first use of the aerosol can, the upper cover 41 separated from the anti-theft base 43 can be fastened by the engagement of the first buckle line 27 and the second buckle line 411, and can be detachably fixed on the actuator body 2, thereby sealing and protecting the actuator body 2 and preventing external dust from contacting the nozzle 23.

[0033] like Figure 4 and Figure 5 As shown, the dust cover 3 is pivotally connected to the spray head 22 and can rotate relative to the nozzle 23. After using the aerosol can, the user can rotate the dust cover 3 to a closed state so that the inner wall of the dust cover 3 completely covers the nozzle 23, effectively preventing external dust from entering the nozzle 23. Even if the upper cover 41 is lost, the dust cover 3 can still independently seal the nozzle 23.

[0034] like Figures 2 to 5 As shown, in this embodiment, the dust cover 3 includes connecting arms 31 extending from both sides, and the nozzle 22 is provided with a guide groove 221 for accommodating the connecting arms 31. The connecting arms 31 are provided with a pivot end 32, and the guide groove 221 is provided with a pivot hole 222 for the pivot end 32 to be inserted. The dust cover 3 is pivotally connected to the nozzle 22 through the pivot end 32 and the pivot hole 222, and can rotate along the guide groove 221 relative to the nozzle 23. The guide groove 221 limits the movement range of the connecting arm 31, prevents the dust cover 3 from deflecting or shaking during the rotation process, and ensures smooth opening and closing. In actual applications, the pivoting method of the dust cover 3 and the nozzle 22 can be replaced by a hinge structure, and the dust cover 3 is opened and closed by the hinge axis.

[0035] like Figures 2 to 4As shown, a limit block 223 is provided on the outer wall of the nozzle 22, and the limit block 223 abuts against the dust cover 3 to limit the dust cover 3 in the covered state from rotating relative to the nozzle 23, so that the dust cover 3 remains stable in the closed state, preventing the dust cover 3 from being accidentally opened due to vibration or accidental touch, and ensuring that the nozzle 23 is always in a sealed state.

[0036] like Figure 2 , Figure 4 and Figure 5 As shown, a protrusion 311 is arranged on the outer side of the connecting arm 31 , which can increase the friction between the user's finger and the connecting arm 31 when the user rotates the dust cover 3 , making it easier for the user to open and close the dust cover 3 .

[0037] In the present invention, the upper cover 41, the anti-theft base 43 and the connecting ribs 42 are integrally formed, which reduces the assembly process and improves the production efficiency while ensuring the uniformity and consistency of the connecting ribs 42.

[0038] The above are only preferred implementation modes of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means shall fall within the protection scope of the present invention.
