Pressing quantitative essence lotion bottle

Abstract

The invention discloses a pressing quantitative essence lotion bottle which comprises an outer bottle body and an inner bottle body, wherein the inner bottle body is arranged in the outer bottle body in a sliding mode, a lotion outlet is formed in the top of the inner bottle body, an air inlet channel is formed in the bottom of the inner bottle body, a piston is arranged in the inner bottle body, a lotion storage cavity is formed between the piston and the lotion outlet, an elastic air bag is arranged on the periphery of the air inlet channel in a sealed and sleeved mode, the bottom of the elastic air bag abuts against the outer bottle body and is provided with a protruding part facing the air inlet channel, the protruding part is provided with an air inlet seam, the bottom of the outer bottle body opposite to the protruding part is provided with an air inlet hole, a reset spring is arranged between the inner bottle body and the outer bottle body on the periphery of the elastic air bag, and the outer bottle body is provided with a limiting part used for limiting the highest position of the inner bottle body. According to the pressing quantitative essence lotion bottle, lotion can be quantitatively discharged in a pressing mode, the lotion discharging amount can be accurately controlled, waste is effectively avoided, and due to the structural improvement, the situation that the exposed pump head limits the appearance design is avoided.

Description

technical field [0001] The invention belongs to the technical field of cosmetic packaging bottles, in particular to a pressing quantitative essence lotion bottle. Background technique [0002] With the gradual improvement of people's living standards, people's demand for cosmetics is increasing, and the shape and material of cosmetic packaging are becoming more and more abundant. 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.

Problems solved by technology

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. Pours a generous amount of lotion easily

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
