[0022] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] like Figure 1 , Figure 2 As shown, this embodiment discloses a lipstick tube, including a tube body 1, an application head 2, and a cap 3. The tube body 1 has an opening 11 at its upper end. The application head 2 is fixedly installed in the opening 11, and at least part of the application head 2 is located inside the opening 11. The application head 2 has an application surface 21 and an outlet hole 22, which connects the application surface 21 and the interior of the tube body 1. The cap 3 is installed in the opening 11. The application head 2 is made of TPE material, and the tube body 1 is made of PE material. The lipstick is stored inside the tube body 1. The lipstick is squeezed out from the outlet hole 22 by squeezing the tube body 1. The application head 2, made of TPE material, is elastic and softer, making it more suitable for application on the lips. The application surface 21 is tilted so that the lipstick squeezed out from the outlet hole 22 can be evenly applied to the lips during use.
[0024] The cover 3 includes a rod 311 located on the inner top surface of the cover 3. The rod 311 extends toward the applicator head 2 and is at least partially located inside the liquid outlet hole 22. The rod 311 is sealed to the liquid outlet hole 22. The applicator head 2 includes a liquid outlet tube 23 located at the center of the liquid outlet hole 22. The liquid outlet tube 23 is located inside the applicator head 2 and extends away from the rod 311. The liquid outlet tube 23 can increase the contact distance between the rod 311 and the inner wall of the liquid outlet hole 22, thus improving the sealing effect between the rod 311 and the liquid outlet hole 22.
[0025] like Figure 2 , Figure 3As shown, the insert 311 includes a ball head 3111, a reduction section 3112, and a transition section 3113. The ball head 3111 is located at the lower end of the insert 311. The applicator head 2 has elastic deformation capability. The diameter of the ball head 3111 is larger than the diameter of the liquid outlet 22. Due to the elastic deformation capability of the applicator head 2, when the cap 3 is fixed to the bottle mouth, the ball head 3111 is at least partially located inside the liquid outlet 22. During the process of the cap 3 closing, the ball head 3111 can be squeezed into the liquid outlet 22. The ball head 3111 and the liquid outlet 22 fit together to achieve a tight seal. The seal can push any remaining lipstick in the outlet hole 22 back into the tube body 1. The reduction section 3112 is located above the ball head 3111. The diameter of the reduction section 3112 is smaller than the diameter of the outlet hole 22. The reduction section 3112 can reduce the contact area between the insert rod 311 and the inner wall of the outlet hole 22, so that only the ball head 3111 contacts the inner wall of the outlet hole 22 when the insert rod 311 is inserted into the outlet hole 22. This reduces the resistance generated between the insert rod 311 and the outlet hole 22 when the cap 3 is closed, making the cap 3 more smoothly closed by the thread.
[0026] The transition section 3113 is located above the reduction section 3112. The diameter of the transition section 3113 gradually increases in the direction away from the reduction section 3112. The maximum diameter of the transition section 3113 is greater than the diameter of the liquid outlet 22. When the cover 3 is completely closed and fixed, a part of the transition section 3113 enters the liquid outlet 22. The outer wall of the transition section 3113 can abut against the upper opening of the liquid outlet 22, which plays a further sealing role.
[0027] More preferably, the end of the liquid outlet 22 located inside the applicator head 2 is provided with an abutment surface 221. The abutment surface 221 corresponds to the curvature of the outer wall of the ball head 3111. The outer surface of the ball head 3111 abuts against the abutment surface 221. When the cover 3 is completely closed and fixed, a part of the ball head 3111 extends downward out of the liquid outlet 22. At this time, the outer wall of the upper half of the ball head 3111 fits against the abutment surface 221 to play a sealing role. The ball head 3111 can play a role in fixing the cover 3.
[0028] like Figure 2 , Figure 4 As shown, since the ball head 3111 of the insert rod 311 is not convenient to be demolded by the cover 3 integrally formed, the cover 3 includes a first cover body 31 and a second cover body 32. The first cover body 31 is fixedly installed at the upper opening of the second cover body 32. The lower end face of the first cover body 31 is provided with an annular groove 3121, and the upper end face of the second cover body 32 is provided with an annular protrusion 321 corresponding to the annular groove 3121. The annular protrusion 321 and the annular groove 3121 are fixedly bonded by ultrasonic welding. The first cover body 31 and the second cover body 32 are fixed by ultrasonic welding. The second cover body 32 is threaded to the pipe opening 11. The insert rod 311 is located at the center of the lower end face of the first cover body 31. The insert rod 311 is concentrically set with the liquid outlet 22. The cover 3 is more convenient to rotate when installed by thread.
[0029] like Figure 1 , Figure 2 , Figure 5 As shown, the inner wall of the cover 3 is provided with multiple protrusions 322. The protrusions 322 are located at the lower end of the cover 3 and are arranged in a ring. The tube body 1 is provided with a boss 12. The protrusions 322 can abut against the boss 12. When the cover 3 is installed to the bottom end by threads, friction is generated between the protrusions 322 and the boss 12, which plays a role in fixing the cover 3 and preventing the cover 3 from loosening.
[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
