[0026] (III) Beneficial Effects
[0027] Compared with the prior art, this utility model provides an anti-loss beverage bottle cap structure, which has the following beneficial effects:
[0028] This bottle cap structure has the advantage of preventing loss. When the user unscrews the cap, the bottle body and cap are connected by a rubber strip to prevent the cap from being lost. Pulling the lever forward causes the limiting block to retract into the cavity and compress the spring, which then flips the cap over and presses it against the top of the frame. Releasing the lever causes the elasticity of the cavity to spring the cap into the limiting groove in the connecting block, thus fixing the cap in place. This prevents the cap from obstructing the user's view or hitting their nose while drinking, thus avoiding interference with normal drinking. It solves the problems of existing bottle caps separating from the bottle body after opening, easily getting lost, affecting subsequent beverage lacing, and the difficulty of recycling small caps due to their scattered size, thus increasing environmental pollution.

[0040] 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.
[0041] Example 1
[0042] See Figure 1-6A non-lost beverage bottle cap structure includes a main component 1, which includes: a bottle body 11 with a bottle cap 12 threadedly connected to its top; a fixing component 2 is provided on the bottle body 11 and the bottle cap 12, the fixing component 2 including: a frame 21 fixedly connected to the outer wall of the bottle body 11; a rubber strip 22, one end fixedly connected to the top of the frame 21, and the other end rotatably connected to the top of the bottle cap 12 via a pivot; a connecting block 23 fixedly connected to the top of the rubber strip 22; a limiting groove 231 formed on the outer wall of the connecting block 23; a cavity 24 formed inside the frame 21; a spring 25, one end fixedly connected to the inner wall of the cavity 24; a limiting block 26 fixedly connected to the other end of the spring 25; and a pull rod 27, one end fixedly connected to the side wall of the limiting block 26 near the spring 25, and the other end penetrating and extending to the outside of the frame 21, the spring 25 being sleeved on the outside of the pull rod 27. The limiting block 26 has a slider 4 symmetrically and fixedly connected to its outer side wall, and the cavity 24 has a groove 41 symmetrically opened on its inner side wall, with the slider 4 slidably connected in the groove 41. The frame 21 is provided with a spring-loaded assembly 3, which includes: a groove 31 opened at the top of the frame 21; a second spring 32 symmetrically and fixedly connected to the bottom surface of the groove 31; and a spring plate 33 fixedly connected to the top of the second spring 32.
[0043] When in use, when the user needs to drink the beverage inside the bottle 11, first unscrew the cap 12. The cap 12 rotates under the rubber strip 22 via the pivot at the bottom of the rubber strip 22. After the cap 12 is unscrewed, the bottle 11 and the cap 12 are connected by the rubber strip 22 to prevent the cap 12 from being lost. Then, pull the lever 27 forward. The lever 27 drives the limiting block 26 to retract into the cavity 24 and compresses the spring 25. Then, flip the cap 12 and press it onto the top of the frame 21. After the connecting block 23 at the top of the rubber strip 22 contacts the bottom surface inside the frame 21, release the lever 27. The elasticity of the cavity 24 will cause the spring 25 to spring into the limiting groove 231 in the connecting block 23, thereby fixing and limiting the cap 12. This prevents the cap 12 from changing position due to gravity when the user tilts the bottle 11 to drink, which would obstruct the user's view or hit the bridge of the nose, affecting the user's normal drinking. After the user finishes drinking, pull the lever 27 forward again, and the limiting block 26 disengages from the limiting groove 231. At this time, rotate the rubber strip 22 back to the front and screw it onto the bottle body 11 again to facilitate carrying the beverage inside the bottle body 11. When the limiting block 26 moves under the influence of the spring 25 and the lever 27, the slider 4 on the side of the limiting block 26 slides in the slide groove 41. The slide groove 41 guides the limiting block 26 and prevents the limiting block 26 from completely disengaging from the cavity 24, which would affect the normal limiting of the bottle cap 12.
[0044] As the user flips the bottle cap 12 and inserts it into the top of the frame 21, the bottle cap 12 pushes the spring plate 33 downward. The spring 32 at the bottom of the spring plate 33 is compressed. When the bottle cap 12 is limited by the limiting block 26, the spring 32 is always in a compressed state. When the operator pulls the lever 27 to release the limitation on the bottle cap 12, the elastic force of the spring 32 pushes the spring plate 33 upward, and the spring plate 33 pushes the bottle cap 12 to pop open, thereby speeding up the speed at which the bottle cap 12 detaches from the frame 21, making it easier to quickly seal the bottle body 11.
[0045] Example 2
[0046] An auxiliary function has been added based on Embodiment 1.
[0047] See Figure 1-6 The limiting block 26 has an inclined surface. The frame 21 has an arc-shaped surface at its edge. The inner sidewall of the groove 31 has a positioning groove 51, and the outer sidewall of the spring plate 33 is fixedly connected to a positioning block 5, which is slidably connected within the positioning groove 51.
[0048] The inclined surface at the top of the limiting block 26 allows the user to fix the bottle cap 12 without pulling the lever 27 in advance: when the user inserts the bottle cap 12 directly into the top of the frame 21, the edge of the bottle cap 12 contacts the inclined surface of the limiting block 26, pushing the limiting block 26 into the cavity 24. The spring 25 is compressed. When the bottom of the connecting block 23 contacts the bottom surface inside the frame 21, the limiting block 26 and the limiting groove 231 are at the same horizontal line. The cavity 24 springs the limiting block 26 into the limiting groove 231, thus automatically fixing the bottle cap 12 and improving the convenience for the user when fixing the bottle cap 12. The frame 21 with its curved edge prevents the user from scratching their hands when carrying or using the bottle 11. When the spring plate 33 moves up and down, the positioning block 5 on the side of the spring plate 33 slides in the positioning groove 51. The positioning block 5 and the positioning groove 51 restrict the lateral movement of the spring plate 33 during the sliding process, thereby preventing the spring plate 33 from tilting.
[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
