[0032] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1-Figure 3 Shown is a fold-resistant high-barrier bottle, which includes: a bottle body 1, a bottle cap 3 and a locking ring 4; a bottle mouth 104 is arranged on the top of the bottle body 1, and the bottle body 1 is provided with multiple layers, and the multi-layer bottle body 1 is composed of a first bottle body 101, a second bottle body 102 and a third bottle body 103 wrapped together from the outside to the inside, and the three-layer bottle body is wrapped, so that the bottle body is compact and the stability is greatly improved.

[0035] A plurality of cavities 2 are vertically penetrated in the second bottle body 102, and the independent air cavity can greatly reduce the influence on the barrier property and stability of the bottle body 1 itself when the bottle body is damaged. The heat insulation layer formed by the cavity 2 greatly improves the heat resistance of the barrier bottle, and at the same time expands the temperature range of the storable and transportable substances, enhances the air tightness of the bottle body 1, and makes the barrier capacity more perfect. In addition, the material selection can be recycled during use while coping with various environmental conditions, which helps to reduce resource waste and environmental pollution and reduce production costs.

[0036] When manufacturing the bottle body 1, each cavity 2 is equipped with an injection tube 201 extending to the outside of the first bottle body 101, which can connect the cavity 2 and inflate it, so as to enhance the airtightness of the bottle body 1, improve the folding resistance of the bottle body, protect the bottle body 1, and alleviate collision losses.

[0037] Figure 4 and Figure 8 In addition to the design of the bottle body structure, the bottle cap 3 is locked with the bottle mouth 104 of the bottle body 1 through a thread, and the way to achieve this effect is that a spiral thread protrusion 105 is fixed on the top outer circle of the bottle mouth 104, and a plurality of vertical grooves 106 are evenly arranged on the uppermost circle of the thread protrusion 105. In the process of making the bottle cap 3, a thread protrusion 301 is arranged in the inner cavity of the bottle cap 3, and a plurality of vertical buckles 302 are arranged on the uppermost circle, which are locked with the outer circle of the top of the bottle mouth 104. The vertical grooves 106 provided on the uppermost circle of the threaded protrusions 105 fixed in a circle correspond to each other one by one. When the bottle cap 3 is rotated to the lowermost position during use, the vertical grooves 106 are fixed with the vertical buckles 302 to prevent the bottle cap 3 from loosening during transportation and causing leakage. Each vertical buckle 302 is "L"-shaped, and one protruding end points in the clockwise spiral direction, so that the bottle cap 3 can be completely locked when the vertical buckle 302 is connected to the vertical grooves 106.

[0038] Figure 5 and Figure 6 It is shown that, in the process of making the bottle bottom 110, making a concave curved surface in the bottom helps to stabilize the bottle body, and there are multiple air holes between it and the flat partition 111 that penetrate the groove of the second bottle body 102. By filling gas, multiple air cavities are formed, which have a good effect on protecting the bottle body 1 or blocking substances.

[0039] It is worth mentioning that Figure 7 and Figure 8As shown, when making the bottle mouth 104, the locking ring 4 is fixed to the outer ring of the neck of the bottle body 1, and a circle of piston ring 401 is arranged inside the top thereof, and the bottom end thereof is connected with an annular plane 402 which moves vertically with the inner cavity of the locking ring 4, and the inner cavity of the locking ring 4 is connected with each cavity 2. In the process of tightening the bottle cap 3, the bottom of the bottle cap 3 squeezes the annular plane 402, compresses the gas in the inner cavity of the locking ring 4, and forms a pressurized cavity, so that the internal pressure of the cavity 2 is increased, and the three-layer protection of the bottle body 1 is enhanced. When the bottle cap 3 is unscrewed, the annular plane 402 is reset through the elastic pullback of the piston ring 401, and the gas in the cavity 2 is expanded, the volume is increased, and the pressure is reduced. It can be used multiple times. When the bottle cap 3 is locked with the bottle mouth 104 through the thread, the bottom of the bottle cap 3 squeezes the annular plane 402, and squeezes the gas in the inner cavity of the locking ring 4 into the cavity 2 through the soft partition 403 fixed on the connecting port 202, so as to form a heat insulation layer, which greatly improves the heat resistance of the barrier bottle, and at the same time expands the temperature range of the storable and transported substances, enhances the air tightness of the bottle body 1, and makes the barrier capacity more perfect. A plurality of partitions 203 inclined toward the bottle mouth 104 are provided in each cavity 2, and the angle between the partitions 203 and the first bottle body 101 is 30°-60°, which can better buffer the extrusion and collision and reduce the damage to the bottle body.

[0040] It can be seen that the ingenious structural design of the present invention lies in that the three-layer bottle body is designed to be wrapped, so that the bottle body is compact and the stability is greatly improved. By injecting gas into the injection tube 201, the air tightness and heat resistance of the bottle body 1 are enhanced. The bottle cap 3 is locked with the bottle mouth 104 of the bottle body 1 through a thread to prevent the bottle cap 3 from loosening during transportation. When the bottle cap 3 is tightened, the air in the locking ring 4 is squeezed out, and the vertical groove 106 and the vertical buckle 302 are mutually locked, and the piston ring 401 elastically fixes the pressure on the bottle cap 3, forming a solid The structure can prevent the bottle cap 3 from loosening during transportation and causing leakage. When the bottle cap 3 is unscrewed, the piston ring 401 is elastically pulled back, the annular plane 402 is reset, the gas in the cavity 2 is expanded, the volume is increased, the pressure is reduced, and it can be used multiple times. The independent air cavity can greatly reduce the impact on the barrier property and stability of the bottle body 1 itself when the bottle body is damaged. The heat insulation layer formed by the cavity 2 greatly improves the heat resistance of the barrier bottle. While expanding the temperature range of the stored and transported substances, it enhances the air tightness of the bottle body 1 and makes the barrier capacity more perfect.

[0041] The second implementation method:

[0042] Different from the first embodiment, the design of this embodiment is that each cavity 2 is connected to the injection pipe 201 extending to the outside of the first bottle body 101, and gas is injected inwardly. The first bottle body 101 and the third bottle body 103 are both made of thermoplastic saturated polyester material, and the second bottle body 102 is made of a skeleton layer woven from polyester fibers and a tape formed by coating the inside and outside with thermoplastic polyurethane elastomer, which is made by cutting, bonding and heat synthesis.

[0043] Figure 1-Figure 3 It is shown that a three-layer wrapping design is used in the process of making the bottle body 1. The interlayer between the first bottle body 101 and the third bottle body 103 is wrapped with a soft second bottle body 102 with several grooves. The three-layer design reinforces the structure of the bottle body 1. The second bottle body 102 uses a skeleton layer woven from polyester fibers that are resistant to sunlight aging and have high strength, and a tape formed by coating thermoplastic polyurethane elastomer inside and outside. The second bottle body 102 is made of cutting, bonding and thermal synthesis. The material used for the second bottle body 102 has excellent plasticity and elasticity, and has excellent properties of high strength, high toughness and wear resistance. As an intermediate bottle body, it can greatly cushion the collision of the bottle body.

[0044] Figure 1-Figure 3 It is shown that the first bottle body 101 is made of thermoplastic saturated polyester material, and the third bottle body 103 is made of the same material as the first bottle body 101. The PET material used is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface, high strength, high toughness, creep resistance and fatigue resistance. It is suitable for making impact-resistant products, can protect the bottle body 1, and alleviate collision losses; at the same time, the PET material has good wear resistance, chemical corrosion resistance and electrical conductivity resistance, is less affected by temperature, is suitable for various environmental conditions, and prevents leakage of substances in the bottle; it can be recycled, which helps to reduce resource waste and environmental pollution and reduce production costs; it has good stability against chemicals, low water absorption, resistance to weak acids and organic solvents, and can store substances of different textures. The PET material can be used for a long time in the temperature range of 55-60°C, and can withstand high temperatures of 65°C and low temperatures of -70°C for short-term use.

[0045] Figure 1 and Figure 7It is shown that in order to further improve the barrier property of the bottle body 1, make the invention more innovative and more widely used, each cavity 2 is connected with the injection pipe 201 extending to the outside of the first bottle body 101 in the design. At present, PET material has good heat resistance in high temperature environment, but the cycle is short, it is not resistant to hot water immersion, and it is not resistant to alkali. Therefore, when making the bottle body 1, each cavity 2 is equipped with an injection pipe 201 extending to the outside of the first bottle body 101. The cavity 2 can be connected and filled with different gases to store and transport different substances. For example, nitrogen is filled into the air cavity through the injection pipe 201. The gas has the characteristics of colorless, odorless, high stability and non-flammable. Therefore, the material can be prevented from oxidation or spontaneous combustion in the air cavity, and flammable and explosive substances can be better stored to ensure transportation safety.

[0046] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
