The following are the design points of silicone water cups:
Material and safety
Food-grade silicone: All silicone water cups must use food-grade silicone. This kind of silicone is non-toxic, odorless, chemically stable, insoluble in water and any solvents, and does not react with any substance except strong alkali and hydrofluoric acid, ensuring that no harmful substances will be released under normal use or even in high temperature environments to protect human health.
Additive control: The use of additives must be strictly controlled, and only substances that meet relevant safety standards are allowed to be added to improve the performance of silicone, such as enhancing hardness and improving heat resistance, etc., and additives cannot cause harm to the human body during use.
Appearance design
Diversified shapes: It can be designed into common cylindrical, square, oval, etc., or creative shapes, such as animal shapes, cartoon images, etc., to meet the personalized needs and aesthetic preferences of different users. For example, children's silicone water cups can be designed into cute animal shapes to increase fun and attract children to use.
Rich colors and surface treatments: Silicone water cups can be made into various colors, including transparent colors, solid colors, and colorful patterns. There are also various surface treatment methods. The frosted surface can increase friction, prevent slipping, and has an anti-slip effect; the polished surface is smoother, easy to clean, and has a brighter appearance.
Structural design
Cup body: The thickness of the cup body is generally between 2-5 mm. Too thick will increase cost and weight, and too thin will affect strength and durability. The bottom and edges can be appropriately thickened to improve stability and collision resistance. In addition, it can be designed into a foldable or telescopic structure for easy storage and carrying. The wall thickness at the folding position is usually between 0.5-1 mm, and it is made into a gradient size to avoid squeezing and expansion problems when folding.
Cup cover: Common cup cover designs include screw-on cover, buckle cover, flip-top cover, etc. The screw-on cover has a good sealing effect, but it is relatively troublesome to use; the buckle cover and flip-top cover are more convenient and quick, suitable for sports or outdoor scenes. Silicone sealing rings or gaskets can be added inside the cup lid to enhance the sealing performance and prevent water leakage.
Handle and straw: The handle design should be ergonomic and convenient to hold and carry. Its shape, size and position should be determined according to the overall size and weight of the water cup. For water cups with straws, the straw material is generally silicone, and the diameter and length should be moderate to ensure smooth drinking.
Functional design
Insulation performance: If you want to achieve the insulation function, you can use a double-layer structure or add insulation materials. The vacuum layer formed in the middle of the double-layer structure or filled with insulation materials can effectively reduce heat transfer and extend the insulation time.
Scale mark: Adding scale marks helps users to master the amount of water they drink, which is especially useful for athletes, patients and other people who need to control the amount of water they drink.
Anti-scalding design: A hard plastic ring can be added to the mouth or outside of the cup body or a special heat-insulating silicone material can be used to prevent users from being scalded when they come into contact with high-temperature drinks.
