Detailed implementation manners

[0026] Next, the technical solutions in this embodiment will be clearly and completely described in conjunction with the accompanying drawings in this embodiment. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figure 1 , Figure 2 , Figure 3 shown, this embodiment discloses a cosmetic packaging bottle, including a bottle body 1, a piston 2, an elastic member 3, a button 4, a bottom cover 5, a liquid outlet nozzle 6, a shoulder sleeve 7, and a bottle cap 8. Openings are provided at both the upper and lower ends of the bottle body 1. The piston 2 is installed inside the bottle body 1. A shoulder 12 is provided on the inner wall of the bottle body 1. The shoulder 12 forms a limit below the piston 2. The piston 2 is installed into the bottle body 1 from the upper opening of the bottle body 1 until the lower end of the piston 2 abuts against the shoulder 12.

[0028] As Figure 3 , Figure 5As shown, a liquid outlet nozzle 6 is installed at the upper opening of the bottle body 1. A liquid cavity 11 is formed between the piston 2 and the liquid outlet nozzle 6. The liquid outlet nozzle 6 is provided with a liquid outlet hole 61. The liquid outlet hole 61 communicates the liquid cavity 11 with the upper end face of the liquid outlet nozzle 6. Cosmetics are contained in the liquid cavity 11. When the piston 2 moves upward, the cosmetics can be extruded out through the liquid outlet hole 61.

[0029] The liquid outlet nozzle 6 is fixedly installed on the bottle body 1 through a shoulder sleeve 7. A through hole 72 is opened on the upper end face of the shoulder sleeve 7. A clamping groove 63 is opened on the side wall of the liquid outlet nozzle 6. The clamping groove 63 is clamped with the edge of the through hole 72. A slot 71 is provided on the lower end face of the shoulder sleeve 7. The slot 71 is an annular groove with a downward opening. The upper end of the bottle body 1 is inserted into the slot 71 for fixation. A buckle corresponding to the slot 71 is provided on the outer side surface of the upper end of the bottle body 1. An interference fit is formed between the inner wall of the small-diameter side of the slot 71 and the inner wall of the bottle body 1 to form a seal. More preferably, the liquid outlet nozzle 6 is provided with a baffle 62. The baffle 62 is located at the lower end of the liquid outlet nozzle 6. The outer side wall of the baffle 62 abuts against the inner wall of the shoulder 12. The baffle 62 closes the lower opening of the shoulder 12 to prevent the paste from entering the inside of the shoulder sleeve 7. At the same time, the baffle 62 can also support the inner wall of the shoulder sleeve 7, making the interference fit between the shoulder sleeve 7 and the bottle body 1 tighter and the sealing effect better. The bottle cap 8 is detachably installed on the shoulder sleeve 7. The bottle cap 8 covers the part of the liquid outlet nozzle 6 outside the shoulder sleeve 7 to prevent dust from entering the liquid outlet nozzle 6.

[0030] As Figure 3 、 Figure 4 shown, the elastic member 3 is at least partially located inside the bottle body 1. The elastic member 3 is located below the piston 2. The upper end face of the elastic member 3 abuts against the lower end face of the shoulder 12. The elastic member 3 is hollow inside. The elastic member 3 has the ability of axial elastic deformation. The elastic member 3 includes a corrugated tube body 34. The corrugated tube body 34 can elastically deform along the axis. The elastic member 3 is made of PE material. By pressing the elastic member 3, the corrugated tube body 34 will produce compressive deformation, and then the air inside the elastic member 3 will be compressed. When the force pressing the elastic member 3 is removed, the corrugated tube body 34 can rebound and recover.

[0031] The elastic member 3 includes a first end 31 and a second end 32. The first end 31 is provided with an air hole 311. The second end 32 is provided with an opening. The second end 32 is fixedly connected to the inner wall of the bottle body 1. The upper end face of the second end 32 abuts against the lower end face of the shoulder 12. The opening of the second end 32 communicates the inside of the elastic member 3 with the space below the piston 2. The first end 31 is connected to the button 4. The button 4 is provided with a connecting pipe 411. The connecting pipe 411 is sleeved with the first end 31. The first end 31 and the connecting pipe 411 can rotate relative to each other. The button 4 is provided with a channel 41. The channel 41 communicates the air hole 311 with the lower end face of the button 4. The channel 41 can communicate the inside of the elastic member 3 with the outside.

[0032] More preferably, a ring groove 43 is provided on the inner wall of the button 4, and a step 33 is provided on the elastic member 3. The elastic member 3 is partially located inside the button 4, and the lower end surface of the step 33 abuts against the lower end surface of the ring groove 43. The abutting fit between the step 33 and the ring groove 43 can increase the abutting area between the elastic member 3 and the button 4, making the button 4 more stable when pressing the elastic member 3.

[0033] The space below the piston 2, the space inside the elastic member 3, and the passage 41 form a communicating cavity. Closing the lower opening of the passage 41 and pushing the button 4 towards the piston 2 can compress the communicating cavity, and then the piston 2 moves towards the liquid outlet nozzle 6. Releasing the passage 41 allows the elastic member 3 to recover. During use, by covering the outer end opening of the passage 41 with a finger and pressing the button 4 inward, the air in the communicating cavity will be compressed. The pressure of the compressed air will push the piston 2 towards the liquid outlet nozzle 6, reducing the liquid cavity 11, and the cosmetics in the liquid cavity 11 can be squeezed out through the liquid outlet hole 61. Conversely, when the finger covering the outer end of the passage 41 is released to reconnect the passage 41, the communicating cavity communicates with the external air and loses pressure. At this time, pressing the button 4 cannot push the piston 2 to move. When the force pressing the button 4 is removed, the elastic member 3 elastically deforms and returns to push the button 4 back to the initial position.

[0034] As Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 As shown in

[0035] More preferably, a limiting groove 131 is provided on the inner wall of the bottle body 1. The limiting groove 131 is horizontally arranged. One end of the limiting groove 131 communicates with the guiding groove 13, and the limiting groove 131 is located at the opening end of the guiding groove 13. When the guiding block 42 is at the lowermost end of the guiding groove 13, when the guiding block 42 is at the lowermost end of the guiding groove 13, rotating the button 4 enables the guiding block 42 to enter the limiting groove 131. When the cosmetic bottle is used up, the button 4 can be rotated to make the guiding block 42 snap into the limiting groove 131, locking the axial movement of the button 4 and preventing accidental pressing of the button 4 to cause the extrusion of cosmetics.

[0036] The bottom cover 5 is fixedly installed at the lower end of the bottle body 1. The button 4 passes through the bottom cover 5, and a part of the button 4 extends beyond the lower end surface of the bottom cover 5. The upper end surface of the bottom cover 5 serves as the lower end surface of the guiding groove 13 and the limiting groove 131. The upper end surface of the bottom cover 5 forms a downward limit for the guiding block 42, and the bottom cover 5 forms a downward limit for the movement of the button 4, which can prevent the button 4 from detaching from the elastic member 3.

[0037] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as the protection scope of the present utility model.
