DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figures 1 to 6 In an embodiment of the utility model, a food bottle cap includes a lower cover assembly 1, a middle jacket assembly 2, and an upper cover assembly 3. The lower cover assembly 1, the middle jacket assembly 2, and the upper cover assembly 3 are sequentially spliced and assembled in a vertical direction to form a bottle cap as a whole. The lower cover assembly 1 includes a bottle cap body 101, a conical seat 102, and a fixed cylinder 104. The conical seat 102 is fixed to the outside of the bottle cap body 101. The fixed cylinder 104 is fixed to the outside of the bottle cap body 101 and the middle of the conical seat 102 and protrudes above the bottle cap body 101 and the conical seat 102.
[0024] The upper cover assembly 3 includes an upper cover 301, a crimping column 303, and an exhaust groove 304. The crimping column 303 is fixed to the bottom of the upper cover 301, and the exhaust groove 304 is opened on one side of the outer wall of the exhaust groove 304;
[0025] The middle jacket assembly 2 includes an outer sleeve 201, which is distributed between the conical seat 102 and the upper cover 301. The crimping column 303 is inserted into the inner side of the fixed column 104 and is in an interference fit with the fixed column 104, so as to realize that the outer sleeve 201 is clamped and fixed between the upper cover 301 and the conical seat 102. The exhaust groove 304 is used to perform exhaust operation when the crimping column 303 is inserted into the fixed column 104.
[0026] There are multiple fixed cylinders 104 and crimping columns 303, and the number and position correspond to each other.
[0027] The top of the conical seat 102 is located on the outside of multiple fixed columns 104 and is fixedly connected to the first inner sleeve ring 103. The bottom of the upper cover 301 is located on the outside of multiple crimping columns 303 and is fixedly connected to the second inner sleeve ring 302. The outer diameters of the first inner sleeve ring 103 and the second inner sleeve ring 302 match the inner diameter of the outer sleeve 201.
[0028] In this embodiment: when assembling the bottle cap, it is only necessary to place the outer sleeve 201 on the top of the conical seat 102 and sleeve it on the outside of the first inner sleeve ring 103, and then place the upper cover 301 on the top of the outer sleeve 201, with its crimping column 303 facing and the bottom contacting with the upper end of the fixed cylinder column 104, and at this time, a part of the bottom edge of the second inner sleeve ring 302 is located on the inner side of the outer sleeve 201, and there is still a certain gap between the bottom of the upper cover 301 and the top of the outer sleeve 201;
[0029] After that, it can be transferred as a whole to the external pressing device, and when the upper cover 301 is pressed downward, the bottom of the pressing column 303 is inserted into the inner side of the fixed cylinder 104. During this process, the air inside the fixed cylinder 104 can be discharged through the exhaust groove 304, so that the pressing column 303 and the fixed cylinder 104 are pressed more firmly. At this time, the bottom of the upper cover 301 is attached to the top of the outer sleeve 201, and the overall assembly and fixation of the bottle cap is completed. No external glue and screws are required. Compared with the traditional bottle cap structure fixed by glue and screws, it can effectively avoid the potential safety hazards of glue and screws to food, and it is safer to use.
[0030] It should also be noted that the diameter of the crimping column 303 is 3.05 mm, and the diameter of the recessed hole inside the fixed cylinder 104 is 2.95 mm. Repeated tests have shown that after the upper cover assembly 3 and the lower cover assembly 1 within this numerical range are pressed and fixed together, their firmness is higher than that of glue, and the safety hazards to food caused by rusting screws and harmful gases released by glue are solved.
[0031] Please refer to Figures 2 to 6 A triangular reinforcing rib 202 is fixedly connected to the inner side of the outer sleeve 201 near the top, and the distance from the top of the triangular reinforcing rib 202 to the top of the outer sleeve 201 matches the height of the second inner sleeve ring 302;
[0032] The fixed column 104 is fixedly connected to a limiting guide rail 105 on one side close to the first inner sleeve ring 103, and a positioning block 203 is fixedly connected to the inner side of the outer sleeve 201 near the bottom. The outer sleeve 201 is clamped to the inner side of the limiting guide rail 105 through the positioning block 203 to achieve rotation locking.
[0033] In this embodiment: the triangular reinforcing rib 202 can not only be used to increase the strength of the outer sleeve 201, but also, when the upper cover 301 is attached to the top of the outer sleeve 201, the bottom of the second inner sleeve ring 302 is attached to the top of the triangular reinforcing rib 202, which can enhance the pressing force of the upper cover 301 on the outer sleeve 201;
[0034] The positioning block 203 is clamped on the inner side of the limiting guide rail 105 so that the outer sleeve 201 will not rotate, thereby ensuring the stability of the bottle cap in use.
[0035] Please refer to Figures 1 to 6 The bottle cap body 101, the conical seat 102, the first inner sleeve ring 103, the fixed cylinder column 104, and the limiting guide rail 105 are integrally formed by a casting process, the outer sleeve 201, the triangular reinforcing rib 202, and the positioning block 203 are integrally formed by a casting process, the upper cover 301, the second inner sleeve ring 302, and the crimping column 303 are integrally formed by a casting process, and the top of the upper cover 301 is integrally formed with a customized pattern by a casting process.
[0036] In this embodiment: after the lower cover component 1, the middle jacket component 2 and the upper cover component 3 are formed by the casting process, they are all subjected to the electroplating process. After the electroplating, a coating of about 0.05MM will be attached to the surface of the bottle cap, thus ensuring the overall aesthetics of the bottle cap. The overall processing technology is simple and easy to promote;
[0037] It should also be noted that: the lower edge and the inner side of the bottle cap body 101 can be provided with corresponding connection notches according to the bottle mouth structure, so as to facilitate the connection operation between the bottle cap body 101 and the bottle mouth.
[0038] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
