In addition to the basic functions of better quality cosmetic plastic containers, the design of the labeling function should also be established. Different types of plastic bottles have well-established differences in their production and processing shapes. For example, the shapes of grasping and holding hands cannot be mixed. As one. According to the comparison and transformation of structure and shape, color and principle, it can produce linguistic hints and correct guidance of visual effects. If necessary, some accessories can be designed and solved. With the language of its own way, the operation method of the plastic bottle can be clearly conveyed at a glance. For example, the design requirements for the entrance and exit of hand sanitizer utensils should be able to distinguish how to carry out the actual operation when everyone applies it first, and whether it is pressed by hand or rotated should be well established.

Under normal circumstances, the key to the design of plastic bottles is designed and conceived under the premise of convenient use, even if there are special circumstances. As adolescents and children are childish in their personal behavior and cognitive mentality, they often open some chemical or pharmaceutical plastic bottles without the legal guardian's attention, or even swallow them, causing irreparable adverse effects.

For example, the opening method of some plastic bottles is the diastolic pressure post-spinning method. During the rotation, the bottle stopper must be lightly pressed to open the bottle stopper. Otherwise, no matter how much force or rotation is required, If it cannot be opened, it is a good way to avoid accidents for children. For plastic bottles with barriers, it is a design logic of today's high-end fashion trends, which fully shows that it is a personalized design and expresses the concern for people's goodness.
