Abstract
Description
Technical Field
[0001] This utility model relates to the field of bottle cap technology for drinking water bottles, and more specifically, to a bottle cap with storage space and mixing function. Background Technology
[0002] With increasing health awareness, people are accustomed to carrying their own water bottles when going out. Water bottles are everyday containers used for holding and drinking liquids, typically designed in a cylindrical shape to optimize material utilization and transport stability. They are mostly made of plastic (such as polyethylene terephthalate) or metal (such as stainless steel), and are reusable to reduce the environmental impact of single-use plastic bottles. Water bottles generally consist of a bottle body and a cap, but existing caps only provide a simple seal. Some patients need to take medications or liquid medicines dissolved in water outdoors, but it is inconvenient to carry medications or liquid medicines that require mixing. Therefore, we propose a cap with storage space and mixing function. Utility Model Content
[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a bottle cap with storage space and mixing function.

[0026] In this embodiment, a rubber sealing gasket is provided at the top of the inner cavity of the sealing cover 3 to ensure that the top of the suction nozzle 19 can be sealed.
[0027] For details, please refer to Figure 1 The rotating mechanism 4 includes two rotating bases 20 fixedly connected to the top surface of the feeding cover 2, and a rotating frame 21 rotatably connected between the two rotating bases 20. The end of the rotating frame 21 is connected to the side of the sealing cover 3.
[0028] In this embodiment, the sealing cover 3 can be rotated by the cooperation of the rotating base 20 and the rotating frame 21.
[0029] For details, please refer to Figure 1 , Figure 2 and Figure 6 The fixing mechanism 5 includes a fixing frame 22 fixedly connected to the top surface of the feeding cover 2. An L-shaped card plate 23 is rotatably connected to the inner side of the fixing frame 22. The top end of the L-shaped card plate 23 extends to the top of the card block 18. A spring 24 is fixedly connected to the inner wall of the fixing frame 22. The end of the spring 24 is fixedly connected to the outer side of the top end of the L-shaped card plate 23.
[0030] In this embodiment, the top of the L-shaped clamping plate 23 of the spring 24 is clamped onto the top of the clamping block 18 to fix the sealing cover 3.
[0031] For details, please refer to Figure 1 and Figure 5 The drive mechanism 14 includes an arc-shaped stepped groove 6 opened on the side of the storage cover 1. An actuating block 13 is slidably connected to the inner side of the arc-shaped stepped groove 6. A connecting rod 12 is fixedly connected to the inner side of the actuating block 13. The end of the connecting rod 12 is in contact with the side of the sealing plate 10.
[0032] In this embodiment, the lever block 13 and the arc-shaped stepped groove 6 have a certain damping, so that the lever block 13 and the sealing plate 10 can only be rotated by applying a certain force to the lever block 13. In addition, when used initially, the top and bottom surfaces of the lever block 13 are respectively connected to the inner wall of the arc-shaped stepped groove 6, so as to fix the initial position of the lever block 13.
[0033] For details, please refer to Figure 4 and Figure 6 The storage cover 1 has an upper external thread seat 16 on its top and an upper internal thread groove 17 on its bottom. The top end of the upper external thread seat 16 is threaded into the inner cavity of the upper internal thread groove 17.
[0034] In this embodiment, the feeding cover 2 is installed on top of the storage cover 1 by the cooperation of the upper external thread seat 16 and the upper internal thread groove 17.
[0035] For details, please refer to Figure 4 The top surface of the inner cavity of the lower internal thread groove 15 is in contact with the top surface of the sealing plate 10.
[0036] In this embodiment, the top surface of the sealing plate 10 is guaranteed to seal the leakage hole 8 at the bottom of the storage chamber 7, thereby ensuring the airtightness of the inner cavity of the storage chamber 7.
[0037] Working principle: When leaving the factory, the medicine or solvent can be placed into the inner cavity of the storage chamber 7 for storage. A preservative gas composed of carbon dioxide, oxygen and nitrogen is injected into the remaining space of the inner cavity of the storage chamber 7 through the nozzle 19 to store the solvent. When in use, the connection points between the top and bottom of the lever block 13 and the inner wall of the arc-shaped stepped groove 6 are cut off. At this time, the lever block 13 is rotated to make it rotate in the inner cavity of the arc-shaped stepped groove 6. The lever block 13 drives the connecting rod 12 and the sealing plate 10 to rotate, so that the through hole 11 on the sealing plate 10 rotates to the lower part of the leakage hole 8 below the storage chamber 7, so that the leakage hole 8 and the through hole 11 are concentrically arranged, so that the solvent in the inner cavity of the storage chamber 7 falls into the bottle and mixes with the water phase for administration.
[0038] When a patient needs to store medication outdoors, the upper threaded seat 16 is removed, and the medication is placed into the inner cavity of the storage chamber 7 for storage. When taking the medication, the lever 13 is turned to rotate the connecting rod 12 and the sealing plate 10, causing the leakage hole 8 and the through hole 11 to be concentrically arranged, so that the medication in the inner cavity of the storage chamber 7 falls into the bottle for mixing. The bottom end of the L-shaped card plate 23 can be pressed to disengage its top from the top of the card block 18, thereby releasing the fixation of the sealing cap 3 and opening the sealing cap 3, so that the liquid in the bottle can be poured out from the through hole 11, the leakage hole 8, and the storage chamber 7. The user can then take the liquid from the bottle through the suction nozzle 19.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
