[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-4As shown, this utility model provides a press-type packaging bottle, including: an outer cap 1, an inner cap 2, a bottle body 3, an inner liner 4 for containing cosmetic materials, and a shoulder sleeve 5; the shoulder sleeve 5 is sealed and located on the upper end of the bottle body 3 to form a receiving cavity 6 for housing the inner liner 4; the inner liner 4 is detachably disposed within the receiving cavity 6; the inner cap 2 is sealed and located on the shoulder sleeve 5; the inner cap 2 is provided with a dispensing nozzle; the shoulder sleeve 5 is provided with a dispensing channel 9; the inlet end of the dispensing channel 9 communicates with the inner liner 4; the outlet end of the dispensing channel 9 is provided with... A first inner plug 7 is provided to prevent leakage of cosmetic materials; the discharge nozzle can communicate with the inner liner 4 through the first inner plug 7; an air outlet channel 10 is provided on one side of the discharge channel 9 on the shoulder sleeve 5, which communicates with the receiving cavity 6; a second inner plug 8 is provided at the output end of the air outlet channel 10; the air outlet channel 10 can communicate with the inner side of the inner cap 2 through the second inner plug 8; the outer cap 1, the inner cap 2, and the shoulder sleeve 5 are arranged sequentially from top to bottom at the upper end of the bottle body 3 to form a rugby ball-shaped bottle structure.

[0021] In this embodiment, as Figure 1-4 As shown, the outer cap 1, inner cap 2, and shoulder sleeve 5 are arranged sequentially from top to bottom at the upper end of the bottle body 3 to form a rugby ball-shaped bottle structure. The inner liner 4 is installed in the receiving cavity 6 formed by the shoulder sleeve 5 and the bottle body 3. The bottle body 3 is made of PP material, and its bottom is thin and soft, allowing it to be pressed. In the normal state (i.e., when not in use), the first piston is blocked at the output end of the discharge channel 9, while the second piston is in an unblocked state, and the air outlet channel 10 is always in communication with the inside of the inner cap 2. During operation, pressing the bottom of the bottle body 3 squeezes the inner liner 4 placed in the receiving cavity 6. During the squeezing process, the cosmetic material in the inner liner 4 is conveyed outward through the discharge channel 9. When conveyed to the first inner plug 7... When in position, the movable part of the inner stopper moves upward under the push of the material, so that the discharge end of the discharge channel 9 is connected to the discharge outlet. Finally, the cosmetic material is output from the discharge nozzle through the first inner stopper 7 for user use. During the extrusion process, the inner liner 4 deforms, causing the pressure in the accommodating cavity 6 to change, which in turn pushes the movable end of the second piston to move upward to block the vent. After the extrusion is completed, the bottom of the bottle body 3 is released, and the second piston moves downward under the pressure between the shoulder sleeve 5 and the inner cap 2, thereby connecting the accommodating cavity 6 to restore the bottle body 3 that has been deformed by pressing. The overall structure is stable and can effectively prevent material leakage. At the same time, users can replace the used inner liner 4 according to the actual application to avoid resource waste.

[0022] Furthermore, such as Figure 1-4As shown, the first inner plug 7 includes: a first sleeve 71 with a T-shaped structure and a first rubber pad 72; a first baffle 73 for limiting the first rubber pad 72 is provided in the middle of the first sleeve 71; a material passage hole 75 is provided at the center of the first baffle 73; the first rubber pad 72 is disposed inside the upper end of the first sleeve 71, and its upper and lower ends respectively abut against the lower end of the discharge nozzle and the first baffle 73; a first sealing part 7 adapted to the material passage hole 75 is provided at the bottom of the first rubber pad 72. 4; Several elongated holes for cosmetic materials to pass through are equidistantly arranged at the bottom of the first rubber pad 72 and around the first sealing part 74; the elongated holes can communicate with the material passage hole 75; specifically, in this embodiment, the first rubber pad 72 is a rubber pad made of soft rubber material that can deform under pressure; during operation, the first sealing part 74 of the first rubber pad 72 moves upward under the push of the material, thereby allowing the material outlet channel 9 to flow into the material outlet through the elongated holes on the first rubber pad 72 and finally be output out;

[0023] like Figure 1-4 As shown, the second inner plug component includes: a second sleeve 81 with an inverted T-shaped structure and a second rubber pad 82; a second baffle 83 for limiting the second rubber pad 82 is provided in the middle of the second sleeve 81; a vent hole is provided at the center of the second baffle 83; the second rubber pad 82 is located inside the lower end of the second sleeve 81, and its upper and lower ends respectively abut against the vent end of the vent channel 10 and the second baffle 83; a second sealing part 84 adapted to the vent hole is provided on the top of the first rubber pad 82; The bottom of the first rubber pad 72 and around the first sealing part 74 are provided with a plurality of elongated holes that can communicate with the vent hole. Specifically, in this embodiment, the second inner plug 8 has a similar structure to the first inner plug 7. The second rubber pad 82 is made of soft rubber material and can deform under pressure. When the bottle body 3 is released during operation, the second sealing part 84 of the second rubber pad 82 moves downward under pressure, thereby allowing the vent channel 10 to communicate with the accommodating cavity 6 through the elongated holes on the second rubber pad 82, so that the bottle body 3 can deform and recover.

[0024] Furthermore, the inner side of the outer cover 1 is provided with a blocking column 11 for sealing the discharge nozzle; by setting the blocking column, leakage of cosmetic material remaining in the discharge nozzle can be avoided.

[0025] Furthermore, the outer wall of the shoulder sleeve 5 is provided with an inwardly concave arc-shaped structure 12, which makes it convenient for users to hold and open the packaging bottle.

[0026] This utility model discloses a press-type packaging bottle with a stable overall structure, which can effectively prevent material leakage. At the same time, users can replace the used inner liner 4 according to the actual application, thus avoiding resource waste.

[0027] 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.
