In the design of perfume bottles, synaesthesia has its own unique characteristics. Smell and vision can transform and communicate with each other, and convey emotions skillfully through sensory transfer, thereby strengthening people's feelings. Designers can make the design of perfume bottles achieve the unity of form and connotation through the rational use of visual and olfactory synaesthesia, and finally realize the information transmission and emotional connection between consumers and designers.
Today, with the continuous improvement of material life, people's requirements for perfume are no longer limited to the fragrance itself, but more attention has been paid to the physical and psychological impact of perfume on people, and more attention is paid to the emotional needs that perfume brings to people. In the process of feeling perfume, through the interaction of eyes and nose, visual and olfactory responses are aroused, resulting in inner emotional fluctuations, and synaesthesia is produced in this process.

1. Perfume bottle design
Perfume is a chemical product whose main ingredients are alcohol, distilled water and essence, which can emit a long-lasting, rich and pleasant fragrance. Because perfume is volatile, perfume bottles are generally made of glass. Glass is non-corrosive and generally does not react with chemicals, so it can store perfume well. Glass has high transparency, clarity and strong The plasticity of the perfume can not only show the texture and color of the perfume, but also show various distinctive shapes, so that the perfume bottle can achieve the unity of practicality and decoration. This is why most of the perfume bottles on the market today are packaged in glass. Therefore, in this study, we mainly explore the perfume bottle made of glass.
The meaning of synaesthesia
Synesthesia has always been a topic of concern. In recent years, scholars at home and abroad have also carried out research on synesthesia from different dimensions. Synaesthesia is a kind of psychological activity. Some scholars believe that synaesthesia is a kind of hallucination in thinking, and it is the interaction and mutual communication of different senses produced by people through association. The essential feature of synaesthesia is the exchange of senses. In short, synaesthesia is the exchange of emotions by one sense causing another sense on the basis of sensory experience.
In people's daily life, synaesthesia widely exists. People can imagine and associate their previous sensory experiences, so as to generate more feelings other than visual elements, which can be abstract and indirect feelings, such as simplicity, peace, gorgeousness, happiness, and mystery; they can also be figurative and direct feelings. , such as warm, smooth, deep, harsh, supple and so on. When describing a good singing voice, people use the word "sweet", but "sweet" originally belongs to taste sensation, and "beauty" belongs to visual sensation, but people use the terms of taste and visual sensation to describe auditory experience, "sweet" "In addition to describing the singing voice, it can also describe the appearance of girls. Sweet girls are easy to be liked and give people a happy, happy and beautiful reverie. The word "sweet" will have different meanings in different usage environments. sense experience. In synaesthesia, smell seems to have temperature, color has weight, cold and warmth have image, and all sense organs are connected with each other.

3. The Phenomenon of Olfactory and Visual Synesthesia in Perfume Bottle Design
At this stage, the research on synaesthesia has also shifted from pure feeling to the field of creation, so that synaesthesia is gradually integrated into the design. In the designer's design activities, synaesthesia makes the designer no longer limited by a single sense, but awakens another sense of people through the intercommunication of the sense organs. Through the function of synaesthesia, vision can transmit information such as taste, hearing, smell, touch, etc., so as to break through the limitations of time and space, let people's senses communicate with each other, and sublimate emotions. In the design of perfume bottles, designers can communicate vision and smell through synaesthesia, so as to realize the emotional connection between consumers and designers. For example, Dior's true self perfume, as shown in Figure 1, the bottle is designed with a narrow neck and delicately wrapped with precious gold threads. The transparent teardrop-shaped glass stopper is embellished on the top of the bottle, which is extraordinary. The bottleneck design is unforgettable. The design is inspired by the clothing of Dior's haute couture fashion. The shape of the entire bottle is like the graceful curve of the female body, showing femininity. The bottle is decorated with a golden collar design, expressing the women of perfume through anthropomorphic decoration. characteristic. The visual appearance of the perfume bottle is gold and the image of a woman's perfume bottle. The classic feature is the golden and curved bottle shape. Through the effect of synesthesia, people will have olfactory associations - seductive, charming and pleasant fragrance. , When people smell the fragrance, their minds will automatically appear confident, elegant and charming after using this fragrance. This is the magic of synesthesia. The designer fully mobilized the two sense organs of vision and smell, and used synaesthesia for emotional fusion, which enriched the information conveyed by the design and enhanced the appeal of this fragrance.
Fourth, the three processes of olfactory and visual synaesthesia in perfume bottle design
In the "Five Senses Theory", Kenya Hara emphasized that design should fully mobilize the senses of touch, hearing, sight, taste, and smell of consumers, liberate design from a single sense, and enable consumers to obtain the A richer, more subtle sensory experience. In synaesthesia, one sense can arouse the excitement of another sense. The design of the perfume bottle is an experience design that integrates multiple senses such as vision and smell. For a perfume bottle, when people see it, they often feel Associating its smell, when you smell it, you will associate some pictures in your mind, so as to form your overall perception of this fragrance. This series of reactions are the result of synaesthesia of sight and smell. Through the mutual communication and transformation of these senses, the fusion of emotions is achieved. In the design of perfume bottles, synesthesia is mainly divided into three processes: "visual stimulation - smell, visual communication - emotional sublimation".
(1) Visual stimuli
When people receive external information, more than 80% come from vision. Vision is the key to attracting consumers' attention. How to successfully make a product attract consumers, and arouse their interest and desire to buy, vision has become the primary The problem. Visual stimulation is the basic condition for the existence of synaesthesia. In the design of perfume bottles, using vision to attract consumers is an effective way to design perfume bottles. Perfume bottle as an important carrier of perfume, its rich physical changes can not only allow people to use it conveniently, but also allow people to gain the feeling of beauty and the edification of art. In the process of design and creation, there are various forms of expression in art forms. Vision is one of them. Vision is a symbolic language that can convey emotions. It conveys specific information and meaning to people through elements such as color and shape. In the design of perfume bottles, designers should contemplate their own designs.
By using visual language to accurately express, let the simple form present a rich visual experience. For example, when designing perfume bottles, designers use smooth lines with delicate decorations to attract the attention of consumers. The perfume bottle itself is an exquisite handicraft. The bottle is like the beautiful clothes of perfume. The visual experience of the bottle directly affects the consumer's first impression of the perfume. Only beautiful visual stimulation can arouse consumers' desire to buy. The design of the perfume bottle is not only for the visual needs, but also to express the inner characteristics and emotions of the perfume. When designing and creating, designers use synesthesia to transform abstract feelings, and use thinking elements and visual language to convey aesthetic experience to consumers, guide inner feelings through visual forms, and finally achieve the shape and meaning between consumers and design objects. mutual transmission. Designers can guide consumers to make correct associations and imaginations through the successful grasp of vision, so as to achieve information communication and emotional connection between consumers and designers. The shape of the perfume bottle is a visual form with an explanatory nature. Through the application of design thinking, the form is visualized by the use of visual language, so as to achieve emotional transmission. People's visual thinking is expressed through visual forms. If the visual form can penetrate into the inner layer of visual thinking, it will stimulate people's associations and imaginations, and make people have emotions and feelings. It can be seen that the visual stimulation of perfume bottles is an important basis for establishing consumers' first impression of perfume, and it is also an important carrier for designers to convey design emotions.
