Description

Technical Field

[0001] This utility model relates to the field of cup technology, and in particular to a thermos cup. Background Technology

[0002] Most of the decorative rings on existing thermos cups are fixedly connected, such as by gluing or one-piece molding. Although they can cover the edge of the cup mouth, stains are easy to accumulate on the upper part of the outer perimeter of the cup lid inside the decorative ring. Since they cannot be removed, the stains in the gaps are difficult to clean thoroughly. Long-term use can easily breed bacteria, affecting hygiene and appearance, which is especially troublesome for users who pay attention to cleanliness.

[0003] As consumers demand greater convenience in cleaning daily necessities, traditional fixed structures can no longer meet their needs, and there is an urgent need for detachable decorative ring designs to solve the problem of cleaning dead corners. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a thermos cup that is not only easy to assemble and disassemble, but also easier to clean and more hygienic.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A thermos cup includes a cup body and a cup lid. The lower end of the outer periphery of the cup lid is provided with an external thread for connecting to the cup mouth. The upper end of the outer periphery of the cup lid is provided with a decorative ring for covering the edge of the cup mouth. The upper end of the outer periphery of the cup lid is provided with a first annular flange. The upper surface of the decorative ring is provided with a first annular groove. The first annular flange is embedded in the first annular groove and is detachably connected to it.

[0007] Furthermore, the first annular flange is symmetrically provided with locking blocks; the first annular groove is symmetrically provided with locking slots on its groove wall, and the locking blocks engage with the corresponding locking slots.

[0008] Furthermore, the first annular flange has a first notch symmetrically opened on its outer periphery, and the two locking blocks are respectively disposed in the corresponding first notches; the lower surface of the decorative ring is provided with a second annular groove, and a second annular flange is formed between the first annular groove and the second annular groove on the inner peripheral wall of the decorative ring. The locking groove has a second notch opened on the outer periphery of the second annular flange, an extension portion disposed on both sides of the opening of the second notch and extending upward, and a stop portion connected to the upper part of the two extension portions.

[0009] Furthermore, when the card block engages with the corresponding card slot, the lower surface of the first annular flange abuts against the bottom wall of the first annular groove, the upper surface of the card block abuts against the lower surface of the stop portion, and the card block is located between the two extension portions of the corresponding card slot; the two side walls of the first notch are respectively provided with gaps on the opposite side of the corresponding card block, so as to avoid the corresponding extension portion when the card block engages with the card slot.

[0010] Furthermore, both the upper and lower ends of the outer end of the card block are rounded.

[0011] Furthermore, the upper surface of the stop portion is flush with the upper surface of the decorative ring; the extension portion, the stop portion, and the decorative ring are integrally formed.

[0012] Furthermore, a sealing ring groove is provided on the outer periphery of the cup lid below the external thread, and a sealing ring for sealing the cup lid and the cup body is sleeved in the sealing ring groove.

[0013] Furthermore, the upper end of the cup lid is provided with a drinking spout, which has a water outlet communicating with the cup body and a flip cover for closing the water outlet.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] First, it's easy to install and remove: To remove, press any adjacent area of ​​the slot on the decorative ring to separate the slot from the corresponding clip. Once the clip is completely detached from the slot, the decorative ring is removed. To install, first align one clip on the cup lid with the corresponding slot on the decorative ring's annular groove and insert it. Then, press the other clip on the cup lid into the other slot of the annular groove to complete the installation of the decorative ring. The operation requires no tools and is simple and effortless.

[0016] Secondly, cleaning is more convenient: After the decorative ring and the cup lid are removed, the upper part of the cup lid located inside the decorative ring is fully exposed, making it easy to thoroughly remove residual stains and solving the problem of cleaning dead corners in traditional fixed structures.

[0017] Third, it is more hygienic and reliable: it reduces the long-term hiding of stains, lowers the risk of bacterial growth, odor and mold, ensures drinking safety, and is suitable for hot water, tea and other scenarios. Attached Figure Description
