A small class of glass bottle
1.Glass bottles are mainly used for cosmetics: skin care products (creams, lotions), perfumes, essential oils, nail polishes have a small capacity, and the capacity of more than 200ml is rarely used in cosmetics. Glass bottles are divided into wide-mouth bottles narrow-mouth bottles. The solid paste is usually a wide-mouth bottle. It should be equipped with an aluminum cover or a plastic cover. Bottle caps can be used for color sprays and other effects; body lotions or water-based pastes usually use narrow-mouth bottles, which should be equipped with pump heads. If the cap is equipped with an inner plug, the liquid is equipped with a small hole and an inner plug, and the thicker lotion is equipped with a large hole inner plug.

If the cap is equipped with an inner plug, the liquid has a small hole and an inner plug, while the thicker emulsion has a large hole inner plug.
a. Cream bottle series: glass bottle body + double plastic cover (usually 10g-50g)
b. Essence series: glass bottle + plastic pump head or anodized aluminum pump head (relatively high, 20 to 100ml) essential oil bottles are usually brown or colored and colored frosted, which can be protected from light.
c. Toner series: glass bottle + plastic inner plug + shell (above 100ml, pump head can also be equipped)
d. Essential oil bottle series: glass bottle body + inner plug + large cap or drip tip + dropper + anodized aluminum cap
2. Glass bottles are divided into wide-mouthed bottles and narrow-mouthed bottles. For solid pastes, a wide-mouthed bottle is generally used. It is suitable to use aluminum caps or plastic fillings. The caps can be used for color spraying effects; emulsion or water A narrow-mouth bottle is generally used for the agent paste, and a pump head should be used. Pay attention to prevent the spring and ball from being worn. There are a large number of pump heads equipped with glass beads, which are usually used for the test of the material body. For example, the preparation needs to be equipped with an inner plug. , Liquid with small holes is the same as inner plug, thicker emulsion is matched with large hole inner plug.
3. The glass bottles are small and consistent in material selection, beautiful in appearance, and rich in processing technology. The common bottle shapes are twisted, oval, flat, prismatic, cone, etc., and manufacturers often develop series of bottle shapes. The bottle body process includes spraying, transparent, frosted, translucent doped, silk screen, hot stamping, hot silver and so on.
4. Silk screen printing: There are usually two types of glass bottle screen printing, one is high temperature ink screen printing, which is not easy to decolorize, the color is dull, and the effect of purple doping is difficult to produce, and the other is low temperature ink screen printing, which has brighter color. The requirements for ink are high, otherwise it is easy to replace, and attention should be paid to bottle disinfection.
5. For spraying, the cost depends on the area and overlap length.
6. If the glass bottle is molded by hand, there will be a slight deviation in the capacity. It should be tested and the correct capacity indication should be made when replacing. For example, the automatic production line alternates evenly, but the volume requirement is large, the cycle is relatively long, and the capacity Maximize stability.
7. The uneven thickness of the glass bottle can easily lead to damage, or it is easy to be squeezed by the content under severe cold conditions. A reasonable capacity should be tested during filling, and paper should be used for transportation and separated. The product should be packed There is a color box, and the inner support and the middle box can be more anti-vibration effect.
10. The bottle cap process can carry out anodized aluminum lettering, bronzing, and etching lines.
