Description

technical field [0001] The invention belongs to the technical field of cosmetic packaging bottles, in particular to a replaceable pressed essence lotion bottle. Background technique [0002] There are generally two types of traditional lotion bottles. One type only includes a bottle body. The bottle body is closed by a bottle cap. When in use, the bottle cap is opened and the liquid is poured out. The liquid output in this way is difficult to control. It is easy to pour large quantities of lotion, and the unused lotion is exposed to outside air during the pouring process, resulting in a significantly reduced shelf life. There is also a bottle body, which is provided with a pump head type extrusion liquid structure. The long axial length of the lotion bottle takes up a large space, which also leads to the long axial length of the lotion bottle as a whole, and the pump head of the pump head type extrusion liquid structure is generally exposed, which leads to the restriction o...

There is also a bottle body, which is provided with a pump head type extrusion liquid structure. The long axial length of the lotion bottle takes up a large space, which also leads to the long axial length of the lotion bottle as a whole, and the pump head of the pump head type extrusion liquid structure is generally exposed, which leads to the restriction of the appearance design of the lotion bottle, making it difficult to Make the appearance design of the lotion bottle out of the pump head
