Technical Field

[0001] The utility model relates to the technical field of polyester bottle production, in particular to a lightweight PET polyester bottle with a high-pressure resistant structure. Background Art

[0002] Typically, liquid foods such as mineral water, beverages, and ketchup are packaged in lightweight, non-breakable polyester (PET) bottles for cost and safety reasons and then provided to consumers. PET bottles are typically made of polyethylene terephthalate plastic. Liquid foods are placed in cleaned PET bottles, sealed with caps, and labeled with the product name, barcode, or ingredients. Therefore, a lightweight PET bottle with a high-pressure-resistant structure is required.

[0003] The internal structure of existing polyester bottles is relatively simple, and most of them do not have a pressure-resistant structure. When the polyester bottles are squeezed by external force after production is completed, the bottle body will become dented, affecting the production quality of the polyester bottles and making it inconvenient for them to be sold later. At the same time, the bottle body and bottle cap of the polyester bottles are mostly closed by screwing, and the screw-tightening method is not convenient for people to open it later, and it will increase the pain of people's hands when turning the knob, affecting the inconvenience and tediousness of opening the polyester bottle later.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the utility model.

[0021] See also Figure 1-5 The bottle cap 5 is a kind of light PET bottle with high pressure resistant structure, and its outer surface is provided with a plurality of sealing members 11, 12 and 13.

[0022] The driving clamping assembly includes a groove 12, a spring 13, a connecting rod 6 and a hinged rod 7. The groove 12 is opened in the middle position of the top of the sealing cover 5, and the groove 12 extends to the inside of the sealing plug 11. The top of the groove 12 is sleeved with a connecting rod 6 extending to its outside. The inner bottom of the groove 12 is provided with a spring 13 connected to the connecting rod 6. Both sides of the top of the connecting rod 6 are hinged with hinged rods 7. The bottoms of the two sets of hinged rods 7 are hinged at the top of the limit rod 8. Pressing the connecting rod 6 downward can realize the hinged displacement of the hinged rod 7, and then the hinged movement of the hinged rod 7 can realize the pushing and expansion of the limit rod 8, thereby driving the fixing rod 9 to disengage from the fixing groove 10, releasing the fixation of the sealing cover 5. At the same time, the compression of the spring 13 can also be achieved through the connecting rod 6. When the connecting rod 6 is loosened later, the elastic restoring force of the spring 13 can realize the restoration of the limit rod 8 and the components above it, so as to facilitate the completion of the closing and fixing of the sealing cover 5 in the later stage.

[0023] The two sides of the sealing cover 5 and the top of the two groups of limit rods 8 are respectively provided with limit slides and through holes, and the limit slides penetrate into the inside of the through holes and cooperate with them. Through the design of the limit slides and through holes, the installation displacement of the limit rod 8 can be conveniently limited to improve the stability of the displacement of the limit rod 8 in the future. The middle position of the top of the two groups of limit rods 8 and the middle position of both sides of the top of the connecting rod 6 are provided with hinge seats, and the two groups of hinge seats on the same side cooperate with the hinge rod 7. The hinge of the hinge rod 7 can be completed through the installation design of the hinge seat. The rotation work is carried out to facilitate the later pushing of the limit rod 8 to move. A pull block is provided at the middle position of the top of both ends of the sealing cover 5, and the outside of the pull block is evenly provided with anti-slip grooves. The design of the pull block can facilitate the later operator to pull and pull out the sealing cover 5, and the anti-slip grooves can increase friction to prevent sliding during pulling. The sealing plug 11 is made of rubber material, and the sealing plug 11 fits the inner wall of the bottle mouth 4. The design of the rubber material can improve the sealing performance of the sealing plug 11 in the later stage to prevent leakage.

[0024] Working principle: When in use, the polyamide strip 2 is designed to be bonded to the outside of the bottle body 1 first, and then the polyamide rubber ring 3 is put on the outside of the bottle body 1 and the polyamide strip 2 for bonding. Then, through the structural design and material of the polyamide strip 2 and the polyamide rubber ring 3, the overall pressure resistance of the bottle body 1 can be improved, effectively preventing the deformation of the bottle body 1 caused by external force in the later stage;

[0025] When it is necessary to design the opening work of the sealing cover 5, the operator can directly press the connecting rod 6 so that it can move inside the groove 12 to compress the spring 13. At this time, by pressing and moving the connecting rod 6 downward, the hinged expansion work of the hinged rod 7 can be realized, and then the hinged rod 7 can push the limit rod 8 away from the outside of the sealing cover 5. At this time, the moving away of the limit rod 8 can drive the fixing rod 9 to disengage from the inside of the fixing groove 10, so as to realize the closing limit of the sealing cover 5, and then pull the sealing cover 5 to drive the sealing plug 11 to disengage from the inside of the bottle mouth 4, thereby realizing the closing work of the sealing cover 5 and the bottle mouth 4, and there is no need for the operator to rotate and open the sealing cover 5, which increases the convenience and flexibility of opening the cover in the later stage, and the sealing performance of the sealing cover 5 in the later stage can be improved by the design of the sealing plug 11.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
