The common bottle used in supermarket is the emulsion pump head type.

There are two forms of emulsion bottle on the cap. The common emulsion pump is covered by the emulsion pump,  is covered by the squeezing emulsion pump. It can effectively control the extrusion amount of the emulsion,  is well received by the market. The popularization rate is high,  the relative cost is higher. Another is the ordinary bottle cap packaging, but the bottle mouth will often set up very small, which also can effectively control the amount of emulsion 3, but there is no emulsion pump convenient. The main material of the emulsion bottle is acrylic, glass  metal,  the outer packing is mainly for the pursuit of fine  high grade.

The buyers of emulsion bottles are mainly based on large cosmetic enterprises,  buyers have the right to speak on the purchasing price. This is a challenge for the manufacturers of latex bottles.

The use process of emulsion pump head: when the press is pressed, the secondary column is driven by the main column to drive the sub column to compress the spring together. During the compression spring, the outer wall of the piston is rubbed through the inner cavity wall of the body, so that the piston opens the discharge hole of the secondary column; when the piston slides down, the air in the body is discharged through the opening hole of the secondary column.

When sucking liquid, press the pressing head by hand through the main column, auxiliary column  piston to compress the air in the body. After releasing the press head, the spring will move back (up) due to the loss of pressure. At this time, the piston also moves downward through the friction of the inner wall of the main body to close the discharge hole of the auxiliary column; At this time, the liquid storage cavity in the body forms a vacuum suction state,  the glass ball is sucked upward,  the liquid in the bottle is sucked into the liquid storage cavity of the body through a straw.　

The liquid is stored by pressing the head for many times,  the liquid is stored to the main body through multiple suction until the liquid is full.

When the liquid storage cavity of the body is full of liquid, press the pressing head again,  the liquid will be directly ejected  the press mouth through the discharge hole.
