Abstract
Description
Technical Field
[0001] This utility model belongs to the field of thermos cup technology, and specifically relates to a thermos cup lid with a double-opening structure. Background Technology
[0002] Double-opening insulated cups include two spouts, typically a foldable straw spout and a drinking spout. The drinking spout has a flip-top, which is usually hinged to the lid. However, the flip-top is usually connected to the lid via a snap-on structure. The drawback of this structure is that the connection strength of the flip-top is insufficient when connected by a snap-on structure. When subjected to external force, it can easily be opened, causing leakage. Utility Model Content
[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a double-opening structure thermos cup lid to solve the problems existing in the prior art.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0005] A double-opening insulated cup lid includes a lid body with a straw outlet and a direct drinking outlet. A spout is connected to the straw outlet. The lid also includes a flip-top. The lid body has a mounting groove. One end of the flip-top is hinged to the mounting groove, and the other end is fastened to the outer edge of the lid body via a snap-fit. The flip-top is characterized by a flip-top locking mechanism that secures the flip-top in its closed state, improving stability. The locking mechanism includes a mounting cavity on the side wall of the mounting groove. A locking piece is rotatably connected to the mounting cavity via a rotating component. A corresponding limiting groove is provided on the flip-top. When the flip-top is closed, the locking piece rotates into the limiting groove via the rotating component, limiting the flip-top and preventing it from detaching from the mounting groove.
[0006] The nozzle fittings are existing technology and will not be described in detail here.
[0007] Preferably, the flip cover includes two hinged arms, and a direct drinking water outlet sealing part is integrally formed on the front end of the two hinged arms. A cup lid connecting part is integrally formed on the front end of the direct drinking water outlet sealing part, and the cup lid connecting part is snapped onto the outer edge of the cup lid body by a buckle.
[0008] Correspondingly, the cup lid body has a strip-shaped mounting groove corresponding to the two hinge arms; the ends of the two hinge arms are hinged to the mounting groove.
[0009] Preferably, each of the two mounting slots is provided with a flip cover locking member, which locks and limits the two hinge arms.
[0010] Preferably, the locking piece is a fan-shaped body, and the rotating component includes a damped rotating limit rod connected to the top of the mounting cavity. The bottom end of the limit rod is fixedly connected to the fan-shaped body. After the flip cover is closed, the rotating limit rod drives the fan-shaped body to rotate. The top of the fan-shaped body protrudes out of the mounting cavity and is placed in the limit groove. The limit rod is located above the hinge arm, further limiting the hinge arm.
[0011] When in use, the damped rotary connection of the limit rod to the top of the mounting cavity enhances the stability of the hinge arm limit.
[0012] Preferably, the bottom end of the limiting rod is threadedly fixed to the sector-shaped body.
[0013] Preferably, the flip cover is provided with a blocking element, which is placed inside the drinking water outlet when the flip cover is closed.
[0014] In summary, the present invention has the following main advantages:
[0015] This application provides a flip cover locking component to further limit the state of the flip cover after it is closed, which can effectively prevent the flip cover from being accidentally opened and causing water leakage; wherein, the flip cover locking component achieves secondary limiting of the hinge arm through the fan-shaped body and the limiting rod, making the closed state more stable.

[0022] refer to Figures 1 to 6The double-opening insulated cup lid described in this embodiment includes a lid body 1, a straw outlet 2 and a direct drinking outlet 3 formed on the lid body, a straw nozzle 4 connected to the straw outlet, and a flip-top 5. The lid body is provided with an installation groove 6. One end of the flip-top is hinged to the installation groove, and the other end is fastened to the outer edge of the lid body by a buckle. The lid also includes a flip-top locking component, which fixes the flip-top in its closed state, improving the stability of the flip-top after it is closed. The flip-top locking component includes an installation cavity provided on the side wall of the installation groove. A locking piece 7 is rotatably connected to the installation cavity through a rotating component. A limit groove 8 is provided on the flip-top. When the flip-top is closed, the locking piece is rotated into the limit groove by the rotating component to limit the flip-top and prevent it from falling out of the installation groove.
[0023] The nozzle fittings are existing technology and will not be described in detail here.
[0024] Specifically, the flip cover includes two hinged arms 9, and a direct drinking water outlet sealing part 10 is integrally formed on the front end of the two hinged arms. A cup lid connecting part is integrally formed on the front end of the direct drinking water outlet sealing part. The cup lid connecting part is snapped onto the outer edge of the cup lid body by a buckle. The buckle structure is existing technology and will not be described in detail here.
[0025] Correspondingly, the cup lid body has strip-shaped mounting grooves 6 corresponding to the two hinge arms; the ends of the two hinge arms are hinged to the mounting grooves. Each of the two strip-shaped mounting grooves has a flip-top locking element on its side, which locks and limits the two hinge arms.
[0026] The locking plate is a fan-shaped body, and the rotating component includes a damped rotating limit rod 11 connected to the top of the mounting cavity. The bottom end of the limit rod is fixedly connected to the fan-shaped body. After the flip cover is closed, the rotating limit rod drives the fan-shaped body to rotate.
