Description

Technical Field

[0001] This utility model relates to the field of polyester bottle technology, specifically a high-performance double-layer polyester bottle. Background Technology

[0002] High-performance double-walled polyester bottles are bottle devices made of high-performance polyester material for storing liquids. Under the operation of the staff, the bottle cap can be loosened and removed by screwing on the thread and thread plate to open the top opening of the polyester bottle. Then, the liquid to be stored is poured into the inner side of the bottle. After a period of time, the bottle cap is tightened to prevent the liquid from being exposed on the outside.

[0003] Currently, most common polyester bottles on the market are single-layer structures, which have many limitations in use. Single-layer polyester bottles have poor heat preservation performance, making it difficult to meet users' needs for maintaining the temperature of the beverages they contain; liquid or residue easily remains on the inside of the bottle, making cleaning difficult; the outside of the bottle lacks anti-slip design, making it easy to slip when held; at the same time, the sealing structure between the bottle mouth and the cap is not perfect, posing a risk of liquid leakage. These problems limit the user experience and application scenarios of polyester bottles. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide a high-performance double-layer polyester bottle to solve the problems mentioned in the background art, such as poor heat preservation performance of single-layer polyester bottles, difficulty in cleaning the inner side of the bottle, easy slippage on the outer side of the bottle, and poor sealing of the bottle mouth.

[0016] 2. This high-performance double-layer polyester bottle features a polytetrafluoroethylene (PTFE) non-stick coating on the inner side of the inner bottle body.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution: a high-performance double-layer polyester bottle, including an outer bottle body 1, an inner bottle body 2 fixedly disposed on the inner side of the outer bottle body 1, a heat-insulating material 3 fixedly disposed between the outer bottle body 1 and the inner bottle body 2, an annular hot-melt connection part 4 fixedly disposed above the outer bottle body 1 and the inner bottle body 2, a bottom connection structure 5 fixedly disposed below the outer bottle body 1 and the inner bottle body 2, an anti-stick coating 6 fixedly disposed on the inner side of the inner bottle body 2, an anti-slip texture 8 fixedly disposed on the outer side of the outer bottle body 1, a conical bottle 8 fixedly disposed above the outer bottle body 1, and a threaded connecting pipe 9 fixedly disposed above the conical bottle 8.

[0026] A bottle opening 10 is fixedly installed above the threaded connector 9. A bottle cap 11 is movably installed on the outside of the threaded connector 9. A mating thread 12 is fixedly installed on the inside of the bottle cap 11. A sealing gasket 13 is fixedly installed on the inside of the bottle cap 11. First, the liquid is poured into the bottle through the bottle opening 10. The polytetrafluoroethylene non-stick coating 6 on the inside of the inner bottle body 2 has extremely low surface energy, making it difficult for the liquid to adhere. Even if a small amount of liquid or residue remains, it can be easily removed during cleaning. After pouring in the liquid, the bottle cap 11 is screwed into the threaded connector 9 through the mating thread 12 on the inside. The sealing gasket 13 will be squeezed and deformed during the tightening process, filling the tiny gap between the bottle cap and the bottle opening, thereby forming a good sealing environment and effectively preventing liquid leakage. Whether for daily storage or carrying out, there is no need to worry about liquid spillage.

[0027] The insulation material 3 is made of aerogel felt, which has a honeycomb porous structure with a porosity of not less than 90%. The cross-section of the annular hot-melt connection part 4 is an isosceles trapezoid, with the upper base width being smaller than the lower base width. The height of the annular hot-melt connection part 4 is 5-8 mm. The bottom connection structure 5 includes an inward annular groove at the bottom of the outer bottle body 1 and an outward convex annular rib at the bottom of the inner bottle body 2 that is adapted to the inward annular groove. The outward convex annular rib is interference-fitted into the inward annular groove. The anti-stick coating 6 is a polytetrafluoroethylene coating with a thickness of 0.1-0.3 mm and a surface roughness Ra value of not more than 0.5 μm. The anti-slip texture 8 is a continuous spiral protrusion with a height of 1-1.5 mm and a spacing of 3-5 mm between adjacent spiral protrusions.

[0028] Working Principle: When using this high-performance double-walled polyester bottle, firstly, the liquid is poured into the bottle through the bottle opening 10. The polytetrafluoroethylene non-stick coating 6 on the inner side of the inner bottle body 2, with its extremely low surface energy, makes it difficult for the liquid to adhere. Even if a small amount of liquid or residue remains, it can be easily removed during cleaning. After pouring in the liquid, the bottle cap 11 is screwed onto the threaded connector 9 through the inner mating thread 12. The sealing gasket 13 is compressed and deformed during the tightening process, filling the tiny gap between the bottle cap and the bottle opening, thus forming a good sealing environment and effectively preventing liquid leakage. Whether for daily storage or carrying out, there is no need to worry about liquid spillage. When holding the polyester bottle, the continuous spiral anti-slip texture 8 on the outer side of the outer bottle body 1 comes into play. These protrusions increase the contact area between the hand and the bottle body, increasing... Friction ensures stable grip even with sweaty hands or water on the bottle surface, preventing slippage. When maintaining liquid temperature is required, the aerogel felt insulation material 3 between the outer bottle 1 and the inner bottle 2 comes into play. Its honeycomb porous structure and porosity of over 90% greatly hinder heat conduction, convection, and radiation. Whether holding hot water to keep it warm or holding cold drinks to slow melting, it can significantly extend the temperature maintenance time. In addition, the annular heat-fused connection 4 and the bottom connection structure 5 firmly connect the outer bottle 1 and the inner bottle 2 from the top and bottom. The annular heat-fused connection 4 is tightly fused through a heat-fusion process, and the bottom connection structure 5 adopts an interference fit, so that the two bottle layers remain stable during use, ensuring the structural strength and durability of the entire polyester bottle.

[0029] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
