The principle of cosmetic bottle foam pump head

⒈ The dispenser is divided into two types: tie type and screw type. In terms of function, it is divided into spray, foundation cream, lotion pump, aerosol valve, and vacuum bottle.

⒉The size of the plastic bottle pump head is determined by the diameter of the bottle body. The standard spray size is 12.5~24mm, and the water output is 0.1~0.2ml/time. It is generally used for perfume, gel water and other commodity packaging. The diameter is the same as the length of the receiving. It can be determined according to the height of the bottle body.

⒊The standard size of the lotion pump head is 16-38ml, and the water output is 0.28-3.1ml/time. It is generally used for cream and scrubbing products.

⒋Special distributors such as foam pump head and hand button sprinkler head. The foam pump head is a non-air-filled hand pressure pump head, which does not need to be filled to generate foam. It only needs to press lightly to generate quantitative high-quality foam. Usually comes with a dedicated bottle. Hand button sprinklers are generally used on products such as detergents.

⒌The composition of the distributor is relatively messy, generally including: dust cover, tap head, tap rod, gasket, piston, spring, valve, bottle cap, pump body, straw, valve ball (steel ball, glass ball). Can be colored, can be electroplated, can be set with anodized aluminum ring. Because a set of pump heads involves more molds, and the order quantity is large.

⒍The vacuum bottle is generally cylindrical, with a small overall capacity. It relies on the principle of atmospheric pressure, which can prevent cosmetics from forming pollution during use. There are anodized aluminum, plastic electroplating and colored plastic. The price is more expensive than other ordinary containers. Quantity demand is not high.
