Bottles/Containers

Bottles and containers are utensils with narrow opening, and they are suitable for carrying and storing liquids, solids, powders, etc. Many of them can cover the openings with cork stoppers or lids of metals or plastics and the like for tight sealing. The materials used in bottles and containers are chlorinated polyethylene, polypropylene, synthetic resin, glass, ceramics, etc. Bottles and containers include narrow-mouth type, wide-mouth type, droppers, bottles to which push-down nozzles can be attached, squeeze-type wash bottles, etc. They are often used in a wide range of applications, such as industrial use, researches, food-related usage, etc. It is necessary to select the bottle and container made of the materials that do not alter the quality of liquids or solids kept in them, since the heat resistance, chemical resistance and transparency vary by type of bottles and containers. It is also important that they are made of chemically stable materials that do not contaminate the contents, and have high gas-barrier properties so that gases and vapor do not pass through.
