Introduction of glass roller bottle

1. About roller bottles

Roller bottles, also known as rolling ball bottles, are a common type of packaging bottle and are widely used by people. The body of a roller bottle is usually made of plastic and glass. Roller bottles usually have a small capacity, and a roller ball is installed on the bottle head so that people can apply it evenly to prevent liquid leakage, and it also has a massage effect. The roller balls on the head of the roller bottle are plastic and steel balls. Generally, cosmetic eye cream bottles use steel balls, while cheap products such as lipsticks use plastic, depending on the price of the product.

2. Materials and features of roller bottles:

Compared to sprays, roller bottles can apply antiperspirants and body lotions more evenly on the skin surface, and the skin feels cooler after the roller ball rolls over. For use in some designated locations, roller ball products appear more professional. Among them, plastic roller bottles are used for eye creams, and eye creams can be directly applied to the skin around the eyes. The application is even and has a massage effect, which helps to eliminate eye wrinkles and eye fatigue; the cool touch of glass beads and steel balls helps to eliminate eye swelling and is easy to use. The material of the plastic roller bottle has similar characteristics to that of glass, which is not easy to react to the contents, and at the same time overcomes the disadvantage of glass roller bottles being fragile during transportation. Plastic roller bottles can be injected in various colors, and can be injected into bright and sandy effects. Relatively speaking, the cost is low and the grade is not bad. The roller bottle requires good water discharge when in use, and it cannot leak when not in use. The products are vacuum leak tested when leaving the factory, and there is no leakage problem, so you can use it without worry.

3. Application fields of roller bottles

It is generally used as packaging for cosmetic eye creams, perfumes, lipsticks, body lotions, face creams, essential oils, acne liquids, antipruritic liquids, medicines, antipyretic gels and children’s products. Medicinal packaging is another important application field of roller bottles. As a carrier of antipyretic gel, the roller bottle can evenly apply the pharmaceutical gel to the skin that needs heat dissipation, and the cool feeling is more conducive to heat dissipation. It avoids the irritation and discomfort caused by traditional physical heat dissipation and improves the unevenness of manual application.

4. Case: “Roll-on” perfume packaging

The packaging form known as “Roll-on” perfume in the market is actually named according to the characteristics of the bottle mouth structure of the perfume bottle. The bottle type used in this packaging form is generally a cylindrical transparent glass bottle with smaller specifications and dimensions, and the bottle mouth is covered with a “polyethylene roll-on inner cover” and a layer of plastic or metal screw cover. Roll-on inner cover

It is actually a small ball made of polyethylene (or polycarbonate, polypropylene) that is fastened. Most of the ball is pressed into the cover (it can be rotated). When using it, turn the bottle upside down, and the perfume will wet the inner surface of the ball. Then, the ball is brought into contact with the part where the perfume is to be used and slowly rolled to apply the perfume to the predetermined position. Because perfume is highly volatile, glass bottles are often equipped with soft plastic seat rings so that when the screw cover presses down the ball, it can ensure that the bottle has a good sealing effect to prevent the perfume from volatilizing and dissipating.
