[0024] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 6As shown, the present invention provides a replaceable inner bottle packaging bottle, including a shoulder sleeve 1, a pump core 2, an inner bottle 3, and an outer bottle 4. The outer periphery of the shoulder sleeve 1 is provided with a locking protrusion 10 and notches 11 located on both sides of the locking protrusion 10. The notches 11 cut the shoulder sleeve 1 to form a locking part 12. The end of the locking part 12 away from the locking protrusion 10 extends axially to form a folded edge 13. The folded edge 13 has a guide slope 14 that abuts against the pump core 2. The inner bottle 3 is fitted onto the shoulder sleeve 1. The inner bottle 3 is provided with a relief groove 30 opposite to the locking part 12. The inner wall surface of the outer bottle 4 is provided with an annular groove 40 for locking the shoulder sleeve 1. The annular groove 40 is provided with a slot 41. The pump core 2 is threadedly connected to the outer periphery of the inner bottle 3 and presses the locking protrusion 10 into the slot 41.

[0026] Specifically, both the inner bottle 3 and the outer bottle 4 have corresponding cavities and openings at the top. The inner bottle 3 can be inserted into the outer bottle 4 from the top opening of the outer bottle 4, and can also be removed from the top opening of the outer bottle 4. The inner bottle 3 has a bottle mouth that is threadedly connected to the pump core 2. The size of the bottle mouth is smaller than the bottle body of the inner bottle 3. The top of the bottle body is provided with a relief groove 30 adjacent to the bottle mouth. The shoulder sleeve 1 is fitted onto the bottle body of the inner bottle 3. The shoulder sleeve 1 is injection molded from polypropylene. At least one locking protrusion 10 is provided on the outer peripheral wall of the shoulder sleeve 1. Notches 11 are provided on both sides of the locking protrusion 10. The notches 11 cut the shoulder sleeve 1 into at least one locking part 12. The locking part 12 can be bent relative to the body of the shoulder sleeve 1. The folded edge 13 on the locking part 12 is arranged opposite to the end of the pump core 2. When the pump core 2 is screwed tightly to the inner bottle 3, the axially moving pump core 2 can abut against the folded edge 13. The locking part 12 bends toward the inner wall surface of the outer bottle 4 with the assistance of the guide inclined surface 14. The locking protrusion 10 is close to the locking groove 41, so that the locking protrusion 10 and the locking groove 41 switch from the pre-locked state to the locked state, and fix the inner bottle 3 on the outer bottle 4. When the inner bottle needs to be replaced, the pump core 2 is rotated in the reverse direction. The locking part 12, no longer under the action of the pump core 2, can reset. At this time, the locking protrusion 10 and the locking groove 41 switch from a locked state to a pre-locked state. Under external force, the inner bottle 3 is pulled out of the outer bottle 4 without causing wear to the shoulder sleeve 1, effectively improving the service life of the shoulder sleeve 1. In this embodiment, the locking protrusion 10 and the locking groove 41 are provided in two sets, arranged symmetrically opposite each other. Of course, we do not limit the specific number here; more or fewer sets can be set according to the actual situation.

[0027] Furthermore, to prevent the protrusion 10 from misaligning with the slot 41, a positioning groove 42 is also provided on the annular groove 40. The outer periphery of the shoulder sleeve 1 is provided with a positioning protrusion 15 that engages with the positioning protrusion 15, thus achieving a foolproof function between the shoulder sleeve 1 and the outer bottle 4. In addition, by providing the positioning groove 42 and the positioning protrusion 15, the shoulder sleeve 1 can be constrained to rotate with the pump core 2, preventing misalignment between the protrusion 10 and the slot 41.

[0028] Furthermore, the aforementioned replaceable inner bottle also includes a bottle cap 5, which is fitted onto the outer bottle 4. The bottle cap 5 and the pump core 2 are interference-fitted, and the pump core 2 is used to fix the bottle cap 5.

[0029] Furthermore, to improve the service life of the replacement bottle and prevent the interference fit between the bottle cap 5 and the pump core 2 from failing, which would result in the bottle cap 5 being unable to be tightly closed, based on the above specific embodiment, a magnetic ring (not shown) is provided on the outer peripheral wall of the pump core 2, and an iron ring (not shown) corresponding to the magnetic ring is provided on the inner peripheral wall of the bottle cap 5. With this arrangement, when the interference fit between the bottle cap 5 and the pump core 2 wears down due to long-term use, the magnetic ring and the iron ring can ensure that the bottle cap can be tightly closed.

[0030] Furthermore, the angle between the guide slope 14 and the pump core 2 is 5° to 15°. In specific implementation, the angle between the guide slope 14 and the pump core 2 can be freely set according to the depth of the clearance groove 30, the thickness of the shoulder sleeve 1 wall, and the depth of the slot 41. For example, when the angle between the guide slope 14 and the pump core 2 is 15°, after the shoulder sleeve 1 is completely engaged and fixed with the annular groove 40, the locking protrusion 10 is located in the slot 41 to achieve pre-locking. Twisting the pump core allows the locking protrusion 10 to move 0.26 units toward the slot 41 of the outer bottle 4 for every unit the pump core 2 descends. Therefore, under the action of the pump core 2, the locking protrusion 10 can tightly adhere to the slot 41 and lock the inner bottle 3.

[0031] Based on the above specific embodiments, the material of the inner bottle 3 can be polyethylene terephthalate (PET), polyethylene, or biodegradable materials. The inner bottle 3 is made of biodegradable plastic materials, such as bio-based polyester materials polyethylene 2,5-uranoate (PEF) and polybutylene succinate (PBS). The inner bottle 3 is blow-molded, in which the material is gradually expanded using a mold until it resembles the cavity of the outer bottle 4.

[0032] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
