Description

Technical Field

[0001] The utility model relates to the technical field of polyester bottles, in particular to an ultraviolet-resistant easy-to-open and close polyester bottle. Background Art

[0002] Bottles, as packaging containers, are widely used for a variety of products. Special drinking water and beverages generally require isolation from air and UV rays during storage. After vacuuming or other methods are used to remove air, the air volume within the bottle cavity must be kept close to zero. In other words, during prolonged storage, no outside air is allowed to penetrate through the bottle wall. However, existing single-layer plastic bottles fail to meet this gas barrier requirement, are inconvenient to transport and store, and fail to meet the demands of modern beverage processing. Furthermore, existing bottles lack effective UV protection, and prolonged exposure to UV rays can easily compromise the quality of beverages.

[0003] To address the shortcomings of existing technologies, researchers have conducted extensive research and proposed a variety of solutions. For example, a Chinese patent document discloses a multi-layer high-barrier composite bottle [CN201520750055.4], which includes a bottle body, a straw, a sealing sticker, and a buckle. The bottle body is equipped with a straw, and the top of the bottle body is equipped with a sealing sticker. The straw includes a suction end, an insertion end, and an elastic curved section connecting the suction end and the insertion end. The sealing sticker includes a sealing film and a bottom box. The bottom box has a groove with an open top. The bottom of the groove has a straw hole on the right side. The suction end and the elastic curved section of the straw are embedded in the groove.

[0004] The above solution solves the problem of poor gas barrier performance of single-layer plastic bottles in the existing technology to a certain extent, but the solution still has many shortcomings, such as: it is difficult to effectively block ultraviolet rays, which can easily affect the quality of beverages.

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] like Figure 1-6 As shown, a UV-resistant easy-open and close polyester bottle includes a bottle body 1, a bottle mouth connector 11 at the upper end of the bottle body 1, a bottle cap structure 2 connected to the bottle mouth connector 11, a mounting cylinder 3 circumferentially sleeved on the bottle body 1, a sliding sealing assembly 4 is provided on the circumferential outer side of the mounting cylinder 3, and an UV-resistant film layer 5 is provided on the circumferential inner side of the mounting cylinder 3 with one end connected to the sliding sealing assembly 4.

[0026] The bottle mouth connector 11 is threadedly connected to a plug-in connection cylinder 6 , which is circumferentially provided with an annular hollow groove 61 , and an anti-ultraviolet film is loaded in the annular hollow groove 61 .

[0027] The plug-in connection cylinder 6 is threadedly connected to the bottle mouth connector 11. When drinking, the flip cover 22 can be opened or the plug-in connection cylinder 6 can be directly rotated and removed. The opening and closing methods are diverse.

[0028] It can be seen that the bottle cap structure 2 includes a sealing cover 21 arranged at the upper end of the plug-in connecting cylinder 6, the lower end of the sealing cover 21 is plugged into the upper end of the annular hollow groove 61 to form a seal for the annular hollow groove 61, and the upper end of the sealing cover 21 is provided with a flip body 22.

[0029] The annular hollow groove 61 of the plug-in connection cylinder 6 passes through the sealing cover 21 , and the sealing cover 21 can be directly pulled out when replacing the anti-ultraviolet film.

[0030] Obviously, the bottle mouth connector 11, the plug-in connecting cylinder 6 and the bottle body 1 are connected to each other, and the flip cover 22 is provided with an anti-ultraviolet coating around its circumference.

[0031] Furthermore, threaded connection parts 12 are provided on the circumferential outer walls at both ends of the bottle body 1 , and the mounting cylinder 3 and the bottle body 1 are connected via the threaded connection parts 12 .

[0032] After the filling is completed, the cylinder 3 is threadedly connected and installed using the threaded connection portion 12 , and the anti-ultraviolet film layer 5 is circumferentially arranged in the loading gap, thereby forming an ultraviolet barrier for the bottle body 1 .

[0033] Furthermore, a loading gap is formed circumferentially between the mounting cylinder 3 and the bottle body 1 , and the anti-ultraviolet film layer 5 is circumferentially disposed in the loading gap.

[0034] Specifically, the sliding seal assembly 4 includes an annular guide groove 41 provided at both ends of the mounting cylinder 3 , a positioning rod 42 and a sliding rod 43 are provided in the annular guide groove 41 , and the sliding rod 43 is plugged and connected to the positioning rod 42 .

[0035] More specifically, a strip-shaped clearance gap 44 is provided on the installation cylinder 3 , and one end of the anti-ultraviolet film layer 5 passes through the strip-shaped clearance gap 44 and is connected to the sliding rod 43 .

[0036] The anti-ultraviolet film layer 5 can be pulled out of the loading gap and replaced by the sliding rod 43. When the anti-ultraviolet film layer 5 is loaded, the sliding rod 43 is pulled closer to the positioning rod 42, thereby causing the anti-ultraviolet film layer 5 to form a ring wrap in the loading gap. Finally, the sliding rod 43 and the positioning rod 42 are connected and positioned by mutual insertion of the plug-in positioning portion 431 and the plug-in connecting groove 421.

[0037] Preferably, the positioning rod 42 is fixedly arranged on one side of the strip-shaped clearance gap 44, and the sliding rod 43 is slidingly arranged on the other side of the strip-shaped clearance gap 44, and the sliding rod 43 is provided with a plug-in positioning portion 431 on the side facing the positioning rod 42, and the positioning rod 42 is provided with a plug-in connection groove 421 on the side facing the sliding rod 43 for the plug-in positioning portion 431 to be inserted.

[0038] In detail, a foldable and retractable protective connection layer is provided between the side of the positioning rod 42 away from the plug-in connection groove 421 and the side of the sliding rod 43 away from the plug-in positioning portion 431, and the upper and lower sides of the protective connection layer are plugged into the annular guide groove 41.

[0039] When the sliding rod 43 and the positioning rod 42 are connected and positioned, the protective connection layer forms an annular wrap around the installation cylinder 3 to further form a barrier, and when the sliding rod 43 and the positioning rod 42 are connected and positioned, its outer wall remains flush with the outer walls at both ends of the installation cylinder 3.

[0040] To sum up, the principle of this embodiment is: by arranging a plug-in connecting cylinder 6 on the bottle mouth connector 11 at the upper end of the bottle body 1 to connect the bottle cap structure 2, and using the annular hollow groove 61 of the plug-in connecting cylinder 6 to load the anti-ultraviolet film, ultraviolet blocking at the bottle mouth is achieved, and it can be opened and closed by the sealing cover 21, which is convenient for quick opening and closing and replacement of the anti-ultraviolet film. Secondly, a mounting cylinder 3 is arranged circumferentially on the bottle body 1, and an anti-ultraviolet film layer 5 is arranged in the loading gap between the mounting cylinder 3 and the bottle body 1 to achieve ultraviolet blocking on the circumferential outer side of the bottle body 1, and the sliding sealing component 4 is used to realize the pull-out and installation of the anti-ultraviolet film layer 5, which is easy to use and has a good ultraviolet blocking effect.
