[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the illustrative embodiments and descriptions are only used to explain the present invention but are not intended to limit the present invention.

[0020] Embodiment: A replaceable environmentally friendly facial cream jar comprises a bottle body 1, an inner liner 4 arranged in the bottle body 1, and an outer cover 2 detachably connected to the opening of the bottle body 1, the bottle body 1 is provided with a receiving cavity 3 for accommodating the inner liner 4, the top of the receiving cavity 3 is provided with a bottle mouth 6, the inner liner 4 is an integral structure made of the same material as the bottle body 1, the opening of the inner liner 4 is connected to the bottle mouth 6 by a snap-on structure, a gasket 5 is provided at the top of the inner cavity of the outer cover 2, and the gasket 5 completely covers the opening of the inner liner 4 after the outer cover 2 and the bottle body 1 are matched.

[0021] By using the inner liner 4 of the same material as the bottle body 1 and adopting a blister structure, less material is used, which reduces production costs and facilitates overall recycling, thereby improving environmental protection. The snap-fit ​​structure between the inner liner 4 and the bottle body 1 facilitates replacement of the inner liner 4 and is more environmentally friendly.

[0022] In order to facilitate the recycling of the bottle body 1 and the liner 4 together, the bottle body 1 is a PET injection molding structure, and the liner 4 is a PET suction molding structure.

[0023] In order to facilitate the use of a blister structure for the inner liner 4 and ensure that the inner liner 4 is firmly connected to the bottle body 1, the connecting structure includes a flange 7 arranged on the opening edge of the inner liner 4 and a slot 8 arranged on the outer peripheral edge of the bottle mouth 6. The flange 7 and the outer wall of the inner liner 4 form an annular groove 9, and the edge of the bottle mouth 6 extends into the annular groove 9. The annular groove 9 is provided with a protrusion 10 extending into the slot 8 on the side facing the slot 8 to form an elastic snap structure.

[0024] In order to facilitate the gasket 5 to fit tightly against the edge of the inner liner 4 after the bottle cap is tightened and form a stable sealing structure at the edge of the inner liner 4, the top of the bottle mouth 6 abuts against the top of the annular groove 9 to support the flange 7 to prevent deformation of the edge of the inner liner 4. The top of the flange 7 is a sealing plane 11 that fits the gasket 5, and the sealing plane 11 extends along the edge of the inner liner 4.

[0025] In order to further support the flange 7 , a step 12 is provided on the outer periphery of the bottle mouth 6 below the clamping groove 8 , and the edge of the flange 7 abuts against the step 12 .

[0026] In order to facilitate the removal of the liner 4 from the bottle body 1 , the bottle body 1 is provided with a recess 14 for fingers to sink into, and the recess 14 extends to the slot 8 .

[0027] In order to prevent the edge of the flange 7 from deforming and causing the clamping failure between the inner liner 4 and the bottle body 1, the edge of the flange 7 is provided with an outward annular edge 13 to strengthen the edge of the flange 7, and the bottom of the annular edge 13 abuts against the step 12.

[0028] When replacing the inner liner 4 , place two fingers on the concave pit 14 and push upward against the edge of the flange 7 . The inner liner 4 is deformed when the fingers pull down the edge, the protrusion 10 is separated from the slot 8 , and the inner liner 4 is separated from the bottle body 1 .

[0029] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
