Development of patented technology for liquid cosmetic packaging
Development of patented technology for liquid cosmetic packaging
At present, the impact of cosmetic packaging on marketing and the humanized design of packaging are increasingly valued. When traditional packaging methods cannot meet people's needs, relevant domestic and foreign companies and scientific research institutions are competing to innovate in packaging form, quality assurance, comfort, lightweight and environmental protection.
1 Technical problems in cosmetic packaging
Since cosmetics have a certain viscosity, this characteristic determines that it does not have the same fluidity as water. The weakened fluidity makes the influence of gravity insufficient to make the emulsion flow freely. At the same time, designers are required to design a reasonable solution based on its fluidity characteristics. How to use it. Currently commonly used cosmetic packaging containers usually have the following problems in use:
(1) Vertical packaging
Put the lotion into an ordinary bottle container or tubular container, with the bottle mouth opening at the top. When using, invert the container, and you need to use a certain amount of force to press the packaging body to squeeze out the lotion. The characteristics of vertical packaging are simple structure and low cost. The disadvantage is that the output volume cannot be well controlled. Even when the lotion is almost used up, the user has to spend a lot of effort to squeeze out the lotion.
(2) Inverted type
Turn the opening upside down and place it under the container. This method of use can solve the problem of difficulty in taking out the lotion when it is almost used up. However, when the lotion is full, it is easy to squeeze out a large amount of lotion at one time, and after using a certain amount of lotion, , because the inside of the container cannot communicate with the outside air, resulting in negative pressure, which can easily cause the container to deform, affecting the appearance and use experience to a certain extent.
(3) Pump type
The principle of the pump type is to use the pressure difference between the inside and outside of the pump to force the emulsion to flow, thereby achieving the purpose of distributing the emulsion in the container. There are different operating methods among different types of pumps, such as piston type, diaphragm type, booster type, etc., and their specific principles are different. Since there must be a gap between the straw and the bottom of the bottle, the waste problem of the pump type has always been difficult to solve.
(4) Other problems during use
When using cosmetics, you generally need two hands to operate. One hand presses the hand pump or squeezes the packaging body, and the other hand catches the cosmetics. If the user is a disabled person, it is not convenient and will cause great trouble and inconvenience to the user during use. .
(5) The demand for packaging design drives businesses to continue to develop and innovate, and it is popular all over the world.
Cosmetic packaging companies, especially high-end cosmetics, have made efforts and explorations in many aspects such as series packaging design. This is also the future development trend of the packaging industry.
2. Technical development of foreign cosmetic packaging
Nowadays, as cosmetics become more sophisticated and novel, their packaging also begins to be protective, functional and beautiful. As people's requirements for the quality and service of cosmetics continue to increase, countries around the world are also constantly exploring and innovating improvements in the functionality, comfort, humanity, and lightweight of cosmetic packaging.
Cosmetics have now become mass consumer goods and necessities in people's lives. In the process of manufacturing and sales, they can drive the growth of a large number of related industries. At present, the invention and innovation of cosmetic packaging in China mainly focus on the following aspects: (1) Fully exploring the convenience of cosmetic packaging; (2) Humanization and comfort; (3) Miniaturization and lightweight; (4) Satisfying human-machine needs Engineering Requirements.
3 Conclusion
Currently, in the context of the "low-carbon storm" sweeping the world, green environmental protection and sustainable development are not just a slogan, but also a social responsibility and a practical action. More and more well-known cosmetics manufacturers have released their own sustainable development plans and strategic goals, which involve the sustainable development strategy of cosmetic packaging, such as the use of renewable or recyclable raw materials, packaging reduction, etc. Quantitative implementation, recycling and reuse of packaging waste, etc. Therefore, with the global call for sustainable development, the design of cosmetic packaging must not only be technologically innovative, but environmental protection is also an important part of the design concept.
