Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic bottle material returning equipment, in particular to a material returning device for the production of cosmetic bottles. Background Art

[0002] At present, there are residual materials inside discarded cosmetic bottles, and the residual materials are generally liquid or paste. If the discarded cosmetic bottles flow out, the residual materials inside the cosmetic bottles are easy to flow out, which may cause pollution to the environment and affect the ecological environment. For this reason, some large cosmetics manufacturers will recycle cosmetic bottles and reuse the cosmetic bottles after returning the materials. Since the residual materials inside the cosmetic bottles are sticky and easy to adhere to the inner wall of the bottle cavity, the prior art generally adopts a spray device to spray high-pressure water from the bottle mouth into the bottle cavity to flush the residual materials. Since the spray device is outside the cosmetic bottle and is not in direct contact with the inner wall of the bottle cavity of the cosmetic bottle, the effect of the residual materials leaving the inner wall of the bottle cavity is easily affected by the spray distance, the pressure and flow rate of the high-pressure water flow. At the same time, the diameter of the bottle mouth of the cosmetic bottle is generally smaller than the diameter of the bottle body, which is easy to restrict the spray angle of the spray device, forming a flushing dead angle in the bottle cavity, resulting in the inability to thoroughly and comprehensively flush the residual materials, affecting the return effect. Utility Model Content

[0003] The utility model aims to provide a material return device for the production of cosmetic bottles, which can enter the interior of the bottle body to directly remove the residual material adhering to the inner wall of the bottle cavity, thereby improving the material return effect.
