DETAILED DESCRIPTION
[0026] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.
[0027] refer to Figure 1-7 The present embodiment provides a double-layer sealed bottle cap, comprising an upper bottle cap 1 and a lower bottle cap 2 connected by threads, wherein the upper bottle cap 1 comprises an upper cover body 11 and a material storage barrel arranged in the upper cover body 11, wherein a discharge port is arranged at the lower end of the material storage barrel, wherein the discharge port is provided with an aluminum foil diaphragm 13 through an adhesive cover, and the lower bottle cap 2 comprises a lower cover body 21 and a receiving barrel 22 arranged on the lower cover body 21 for receiving the material storage barrel, wherein a sealing cover 23 is provided at the lower end of the receiving barrel 22, wherein the sealing cover 23 is integrally formed with the receiving barrel 22, and a cutting line and a hinge point 2 are provided between the sealing cover 23 and the receiving barrel 22 31, a force-bearing protrusion 232 is provided on the upper surface of the sealing cover 23 on the side corresponding to the hinge point 231, and a hard pointed structure 233 is provided on the upper surface of the sealing cover 23. When the upper bottle cap 1 and the lower bottle cap 2 are about to be tightened, the pointed structure 233 pierces the aluminum foil diaphragm 13 and cuts the aluminum foil diaphragm 13 as the tightening is carried out, and the lower end of the storage barrel presses against the force-bearing protrusion 232, so that the sealing cover 23 and the accommodating barrel 22 are broken along the cutting line, thereby realizing the sealing cover 23 of the accommodating barrel 22 being pushed open, and due to the existence of the hinge point 231, the sealing cover 23 will not fall off and fall into the bottle.
[0028] In practical applications, the sealing cover 23 may also be designed in other forms, such as a sealing plug.
[0029] In this embodiment, a limiting structure is provided between the upper bottle cap 1 and the lower bottle cap 2 to prevent the upper bottle cap 1 and the lower bottle cap 2 from separating. The limiting structure includes a plurality of upper check teeth 14 arranged at intervals along the circumferential direction of the inner surface of the upper cover body and a plurality of lower check teeth 24 arranged along the circumferential direction of the outer surface of the accommodating cylinder 22. There are four upper check teeth 14 and four lower check teeth 24, respectively. The tooth shapes of the upper check teeth 14 and the lower check teeth 24 cooperate with each other to form a bite structure, which improves the impact resistance of the bottle cap during transportation and storage, effectively prevents the possibility of the bottle cap loosening or falling off, and at the same time, it can also provide a certain resistance when the upper bottle cap 1 and the lower bottle cap 2 are tightened to avoid accidental damage to the aluminum foil diaphragm 13 and the sealing cover 23, thereby enhancing the sealing and stability of the bottle cap itself.
[0030] In this embodiment, the upper bottle cap 1 and the lower bottle cap 2 are connected by threads, the threads of the upper bottle cap 1 are arranged on the inner side of the upper cap body 11, and the upper check tooth 14 is located below it, and the threads of the lower bottle cap 2 are arranged on the outer surface of the upper part of the accommodating tube, and the lower check tooth 24 is located below it.
[0031] In this embodiment, an anti-theft ring 3 is also included, the lower end of which is interference-fitted on the lower cover body 21, and the upper end is connected to the lower end of the upper cover body 11 through spaced connection ribs 31. When in use, whether tightening the upper bottle cap 1 or loosening the upper bottle cap 1, the consumer needs to apply enough torque to overcome the connection force between the anti-theft ring 3 and the upper bottle cap 1. During this process, the connection rib 31 will break, separating the anti-theft ring 3 from the upper bottle cap 1. Once the connection rib 31 breaks, the anti-theft ring 3 will not be able to connect to the upper bottle cap 1 again, thereby providing an obvious visual indication that the upper bottle cap 1 has been opened.
[0032] At the same time, the outer diameter of the lower end of the upper cover body 11 is equal to the inner diameter of the anti-theft ring 3. When the connecting rib 31 is broken, the anti-theft ring 3 can make way for the upper cover body 11, making it easier for the upper bottle cap 1 to continue to be tightened downward.
[0033] In this embodiment, a sealing cylinder 25 is coaxially arranged inside the lower cover body 21 and between the accommodating cylinder 22. The upper end of the sealing cylinder 25 is fixed on the lower cover body 21, and the lower end is a free end. The outer surface of the free end is provided with a circle of sealing convex ring 251, and the ring width of the sealing convex ring 251 gradually decreases from top to bottom. This design of the sealing cylinder 25 further enhances the sealing performance between the lower bottle cap 2 and the bottle mouth, and effectively prevents leakage of the contents of the bottle.
[0034] It should be noted that in actual use, in order to facilitate consumers to tighten and unscrew the bottle cap, anti-slip grooves are respectively provided on the upper cover body and the lower cover body. The setting of the anti-slip grooves is a conventional technical means in the field and will not be repeated here.
[0035] The utility model sets the bottle cap into an upper bottle cap 1 and a lower bottle cap 2. When consumers drink instant beverages, they only need to tighten the upper bottle cap 1 and the lower bottle cap 2 to add the liquid, powder or particles in the storage barrel 12 into the beverage bottle, thereby improving the convenience of use. At the same time, the setting of the aluminum foil diaphragm 13 can effectively protect the liquid, powder or particles in the storage barrel from contamination, ensuring the safety and stability of the food. The setting of the pointed structure 233 can automatically pierce the aluminum foil diaphragm 13 during the process of tightening the bottle cap, so that the liquid, powder or particles in the storage barrel can be smoothly added to the bottle without additional operation, further improving the convenience of use; further, the upper bottle cap 1 and the lower bottle cap 2 are detachable. When the product in the storage barrel 12 is not needed, the upper bottle cap 1 can be removed and stored separately, and it does not affect the sealing effect of the lower bottle cap 2 on the bottle mouth.
[0036] In summary, the utility model has the advantages of being easy to use, safe and reliable, and can effectively solve the problems existing in the prior art and improve the user experience and safety of ready-to-drink beverages. It can be widely used in the fields of food and beverages, as well as in other fields such as medicine and cosmetics that require the mixing of two materials, and has broad market prospects and application value.
[0037] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
