[Prior art] Airless bottle system-a container that uses the pressure difference between the inside and outside of an airtight bottle to push the liquid inside the bottle to flow outward. It is conventionally used to contain and retrieve viscous fluid substances. Please refer to Fig. 1. Fig. I is a schematic cross-sectional view of a conventional airless bottle. The two known vacuum bottles use a combination of the extraction device 10 and a vacuum #watt U to generate gas. Then the liquid in the vacuum bottle 11 is driven by the extraction device to flow out of the bottle from the extraction device 10 and the nozzle 12. Among them, the airtight space 16 in the vacuum bottle u for containing the liquid contents is defined by a piston 13, a bottle body 14, and an extraction device. The piston 13 is located above the bottle base 15 at the bottom of the bottle body 14. When the extraction device 10 is squeezed, the liquid is driven out, so that the internal pressure of the vacuum bottle u is smaller than the external atmospheric pressure, and the piston 13 is pushed up to fill the liquid flow The vacuum formed. However, the use of the vacuum bottle 11 is limited by the viscosity of the liquid content. The main reason is that when the viscosity of the liquid content is too large or too small, the piston 13 cannot slide due to the resistance or suction of the liquid content. The traditional vacuum bottle can only draw liquids with a viscosity of about 200 ~ 20,000 cps, and the size of the outer and inner diameters of the piston and the roundness are not precisely matched, which often causes the airtight failure of the vacuum bottle 丨 丨 0 M280348 Controlling the viscosity of the contents can add high-viscosity liquids and limit the traditional vacuum bottles to respond. Therefore, it is necessary to provide a container for taking viscous fluid substances. [New content] = b The purpose of this material is to provide a container that can draw high viscosity liquids and hold two viscous fluid substances. It is characterized by the use of a non-yellow with elastic potential energy to help sell live soil and push it to solve the problem that the viscosity of the liquid content prevents the piston from sliding. > The container for viscous fluid substances provided in this creation includes at least the shell and tube structure, the 奘 蒈, 、, 本, ^ the piston and the spring.

The first embodiment of the present invention discloses a container that utilizes the compression potential of a compression spring and pushes the piston to slide in conjunction with atmospheric pressure to facilitate the extraction of a highly viscous liquid and the use of a viscous fluid substance. The second embodiment of the present invention is to disclose a container that utilizes a stretched position of a tension spring to pull the piston to slide in conjunction with atmospheric pressure to facilitate the extraction of a highly viscous liquid and the use of a viscous fluid substance. According to the technical advantages and features disclosed in the above preferred embodiments, the elasticity of the elastic yellow can surely solve the problem that the liquid viscosity is too large and difficult to obtain, so as to increase the application of the container containing and using the viscous fluid substance. Scope and effect M280348 can achieve the purpose of this creation [Embodiment] This creation is based on the elastic position of the spring in the state of tension, compression, bending or torsion, which can assist the sliding of the piston containing and taking the viscous fluid substance , In order to solve the problem of the vacuum bottle "night body viscosity is too high to be taken out.
