Empty Roll On Bottle 10ml Bamboo

1. Product Introduction

Roll on bottle is a personal care product container,the bottle body, usually made of glass and wood, is used to store liquids, and the bottle mouth is tightly fixed with metal balls through a plastic ring, forming a sealed system. When in use, by inverting the bottle body and applying pressure to the ball, the liquid inside the bottle will wet the surface of the ball. Subsequently, rolling the ball on the skin can evenly and quantitatively apply the liquid.
Its design focuses on precise coating, sealing hygiene, and portable control.

3. Roll on Bottle Advantage

The absolute inertia of glass ensures that it will not react with any active or sensitive ingredients, such as essential oil, essence, perfume oil, etc., to ensure that the product is pure, pollution-free and non deteriorating. The good thermal conductivity of glass allows the ball to provide an immediate cooling sensation when in contact with the skin, with a certain calming and soothing effect, especially suitable for products such as eye gel and soothing massage oil. The glass material has a transparent and gorgeous appearance, which can significantly enhance the product's grade and brand image.
Plastic material is extremely lightweight, very suitable for carrying around in bags, and not easily broken, with a wider range of usage scenarios and high safety. In terms of design, various curved, flat and other special shapes of bottle bodies can be easily made through injection molding, making the brand highly recognizable.

4. Roll on Bottle Principle

Principles of Capillary Action and Fluid Mechanics:When the ball rolls backwards, a small low-pressure area is created behind it.The liquid inside the bottle is adsorbed into the gap between the ball and the bottle wall under atmospheric pressure and capillary action, and thus carried out.The smooth surface of glass is more conducive to the adsorption and conduction of liquids.
Seal Principle:Utilizing the principle of interference fit.The diameter of the ball is slightly larger than the diameter of the glass bottle mouth. Through precision manufacturing and the clamping force of the elastic material (ball seat), the ball is tightly wrapped around the bottle mouth, forming an effective sealing barrier to prevent liquid leakage and evaporation.
