[0002] PET bottles are made of polyethylene terephthalate (PET), the main component of which is polyester. This material is widely used in daily necessities and cosmetics. It can be used as a container for instant food, hot or cold drinks, and can also be used for packaging medicines or cosmetics. PET bottles are available in different specifications and types, with the most common specifications currently being 500ml, 1L, and 1.5L. In actual use, existing PET bottles have good toughness and can withstand certain external impacts, but their puncture resistance is poor and they are prone to perforation by external punctures. In addition, conventional PET plastic bottles have poor barrier effects.
[0003] In order to address the shortcomings of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a PET polyester bottle with antioxidant, heat-resistant and high barrier properties [202122205118.6], which includes a bottle body, a dial fixedly mounted on the outer surface of the bottle body, a base fixedly mounted on the bottom of the bottle body, a label fixedly mounted on the outer surface of the bottle body, a high-temperature insulation mechanism fixedly sleeved on the outer surface of the bottle body, a bottle stopper fixedly mounted on the top of the bottle body, a liquid outlet pipe fixedly mounted on the outer surface of the bottle stopper, a connecting buckle fixedly mounted on one side of the liquid outlet pipe, and a clamping concave plate fixedly mounted on one side of the liquid outlet pipe.

DETAILED DESCRIPTION
[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0023] like Figure 1-4 As shown, a composite stab-resistant polyester bottle includes a main bottle body 1 made of PET. The main bottle body 1 is a transparent structure as a whole. The outside of the main bottle body 1 is covered with a puncture-resistant layer 2 made of PE fiber material to improve its puncture resistance and wear resistance. In order to prevent it from sliding and dislocating, a circumferential limiting component 3 and an axial limiting component 4 are provided between the main bottle body 1 and the puncture-resistant layer 2 to keep the main bottle body 1 and the main bottle body 1 in a fixed position. Reinforcement components 5 are respectively provided at the bottom and top of the main bottle body 1, and the reinforcement components 5 are pressed against the puncture-resistant layer 2. The reinforcement component 5 strengthens the local structure of the main bottle body 1 and cooperates with the upper and lower limiting components to ensure that the puncture-resistant layer 2 is fully in contact with the outer surface of the main bottle body 1.
[0024] Specifically, similar to conventional bottle structures, the main body 1 of this embodiment is provided with a circumferentially encircling structural rib 11 extending from top to bottom. The structural rib 11 protrudes from the outside to the inside, and the top of the main body 1 adopts a threaded bottle mouth. The structural rib 11 mainly maintains the cylindrical structure of the middle portion of the main body 1.
[0025] Furthermore, in addition to the thickening treatment, to enhance the local structural strength of the main body 1, the reinforcement assembly 5 includes a reinforcement base disposed at the bottom of the main body 1 and a reinforcement top surface disposed at the top of the main body 1. The reinforcement base and reinforcement top surface also provide good contact with the stab-resistant layer 2, and when the stab-resistant layer 2 is wrapped around the main body 1, it provides a certain axial positioning.
[0026] Furthermore, the lower edge of the reinforced base is rounded, and a circumferential, outward-protruding reinforcement ring 51 is located in the middle of the base. A centrally symmetrical, triangular reinforcement block 52 is located at the bottom of the base. The base is expanded to enhance the support stability of the bottom of the main bottle body 1 and maintain the puncture-resistant layer 2 in place to prevent it from slipping.
[0027] Furthermore, the reinforced top surface includes a reinforcing curved surface 53 disposed on the top of the main bottle body 1. Reinforcing ribs are arranged symmetrically along the center of the reinforcing curved surface 53 and extend to the structural ribs 11. The reinforcing ribs divide the reinforcing curved surface 53 and cooperate with the structural ribs 11 to maintain the curved surface structure of the main bottle body 1.
[0028] In addition, the circumferential limiting assembly 3 includes an anti-slip layer 31 disposed inside the stab-proof layer 2 to enhance contact friction. Anti-slip bumps 32 are distributed on the anti-slip layer 31. After the stab-proof layer 2 is attached, some of the anti-slip bumps 32 fall into the grooves outside the structural ribs 11 to provide position limiting, while the remaining anti-slip bumps 32 apply additional squeezing force to the main bottle body 1.
[0029] At the same time, similar to the function of the anti-slip bumps 32, an anti-slip strip 33 extending axially is provided on the inner side of the anti-slip layer 31 to improve its circumferential limiting effect and avoid excessive deformation of the anti-stab layer 2.
[0030] It can be seen that the stab-proof layer 2 completely covers the outer side of the main bottle body 1, and the axial limiting component 4 includes an elastic ring 41 arranged on the top of the stab-proof layer 2, and the elastic ring 41 is tightened with the threaded bottle mouth.
[0031] It is clear that the elastic ring 41 is tightly pressed against the mouth of the main bottle body 1, and the elastic fibers are woven into the stab-proof layer 2. The stab-proof layer 2 has good elasticity as a whole, which can meet the protection requirements of main bottles 1 of different specifications, and the main bottle body 1 and the stab-proof layer 2 can be quickly separated as needed.
[0032] Preferably, the sidewall thickness of the main body 1 is 0.35-0.85mm, and the thickness of the puncture-proof layer 2 is 0.50-0.95mm. A main body 1 with a thickness of 0.5mm and a puncture-proof layer 2 with a thickness of 0.6mm is preferred. If necessary, a heat-insulating structure can be added inside the puncture-proof layer 2.
[0033] To sum up, the principle of this embodiment is as follows: the main bottle body 1 is combined with the stab-proof layer 2, the stab-proof layer 2 is coated on the outside of the main bottle body 1, and is fixed in position by the circumferential limiting component 3 and the axial limiting component 4. At the same time, the reinforcing component 5 maintains the upper and lower structural strength of the main bottle body 1, ensuring that the stab-proof layer 2 fits tightly with the main bottle body 1, so that the main bottle body 1 has a good stab-resistant effect.
[0034] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
[0035] Although this document frequently uses terms such as main bottle body 1, structural rib 11, anti-puncture layer 2, circumferential limiting assembly 3, anti-slip layer 31, anti-slip protrusion 32, anti-slip strip 33, axial limiting assembly 4, elastic ring 41, reinforcement assembly 5, reinforcement ring 51, reinforcement block 52, and reinforcement arc surface 53, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
