Description

Technical Field

[0001] This invention relates to an improved invention of a thermos cup, and more particularly to an improved invention of a thermos cup that requires no washing. Background Technology

[0002] Cups play a vital role in people's daily lives. Depending on daily needs, different types of cups are chosen. Especially in summer and winter, or when traveling, insulated cups play a crucial role in keeping hot or cold water warm, making life more convenient. Currently, the market offers a wide variety of insulated cups. However, when regular insulated cups are stored with acidic beverages, milk, or traditional Chinese medicine containing acidic substances for extended periods, residues can remain inside, causing the cup to develop an odor. Furthermore, using insulated cups to brew tea or coffee can lead to the accumulation of tea and coffee stains at the bottom over time, which can be harmful to health. To address these issues, frequent cleaning with a toothbrush or long-handled cup brush is necessary, which is not only troublesome but also time-consuming and laborious. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an insulated, wash-free cup.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the insulated cup includes an insulated cup body and a cup lid, characterized in that: a disposable cup body is replaceably provided inside the insulated cup body, a cup support portion is provided on the outer side of the cup mouth of the corresponding insulated cup body, the upper end of the cup support portion is higher than the cup mouth of the insulated cup body, and the upper end of the cup support portion is engaged with the rolled mouth of the disposable cup body, the lower end of the cup support portion is supported and engaged with the stepped surface on the outer side of the insulated cup body, and the cup lid is sealed with the disposable cup body.

[0005] The inner surface of the cup lid is provided with a stopper, and the stopper is provided with a first sealing structure, which is sealed and fitted with the inner wall of the disposable cup.

[0006] The first sealing structure is a first sealing ring, which is embedded in an annular groove on the outer peripheral surface of the plug.

[0007] The inner surface of the cup lid is provided with a second sealing structure, which is in a sealing fit with the mouth of the disposable cup.

[0008] The second sealing structure is a second sealing ring, which is embedded in an annular groove on the inner cover surface.

[0009] The cup holder is detachable and has a size and structure that can adapt to different disposable cup shapes.

[0010] The disposable cup body is a paper cup or a plastic cup.

[0011] The cup holder is integrally formed with the disposable cup body.

[0012] The beneficial effect of this invention is that the improved insulated cup is a disposable cup body that can be replaced and installed inside the insulated cup. When drinking, the liquid can be poured directly into the disposable cup body, and the lips will come into contact with the cup holder covering the mouth of the insulated cup body, avoiding direct contact and contamination between the liquid and the mouth and the insulated cup body. After drinking, the disposable cup body can be replaced directly, achieving the effect of not needing to wash the insulated cup body and not mixing flavors. Attached Figure Description

[0013] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0014] Figure 1 This is a schematic diagram of the structure of the present invention.

[0015] Figure 2 For the present invention Figure 1 Enlarged view of part A. Detailed Implementation

[0016] The accompanying drawings illustrate the structure of the present invention, and further details will be described below in conjunction with the drawings. In this embodiment, the insulated, washable cup includes an insulated cup body 1 and a cup lid 2. The cup lid 2 is screwed onto the insulated cup body 1 using a threaded structure. A disposable cup body 3 is replaceably provided inside the insulated cup body 1. A cup support portion 4 is fitted onto the outer side of the cup opening of the insulated cup body 1. The upper end of the cup support portion 4 is higher than the cup opening of the insulated cup body 1, and the upper end of the cup support portion 4 engages with the rolled edge of the disposable cup body 3. The lower end of the cup support portion 4 supports and engages with the stepped surface 5 on the outer side of the insulated cup body 1. The cup lid 2 and the disposable cup body 3 are sealed together.

[0017] When using this invention, the disposable cup body 3 can be placed inside the insulated cup body 1, and the rolled mouth of the disposable cup body 3 is held by the cup holder 4. Then, the beverage is poured into the disposable cup body 3, and the cup lid 2 is placed on the insulated cup body 1 to seal the mouth of the disposable cup body. After drinking, the disposable cup body 3 can be directly replaced, achieving the effect of not needing to wash the insulated cup body 1 and not allowing the flavor to transfer. The cup lid 2 only needs to be rinsed.

[0018] As a further improved embodiment, a stopper 6 is provided on the inner surface of the cup lid 2, and a first sealing structure 7 is provided on the stopper 6. The first sealing structure 7 is in a sealing fit with the inner wall of the disposable cup body 3. Preferably, the first sealing structure 7 is a first sealing ring, which is embedded in an annular groove opened on the outer peripheral surface of the stopper. This ensures the airtightness of the disposable cup body 3 and reduces the possibility of liquid leakage from the disposable cup body 3.

[0019] As a further improved embodiment, a second sealing structure 8 is provided on the inner surface of the cup lid 2. The second sealing structure 8 is located on the outer periphery of the stopper 6 and is in a sealing fit with the mouth of the disposable cup 3. Preferably, the second sealing structure 8 is a second sealing ring, which is embedded in an annular groove opened on the inner surface of the lid. This further ensures the sealing performance of the disposable cup 3 and reduces the possibility of liquid leakage from the disposable cup 3.

[0020] As a further improved embodiment, the cup holder 4 is detachable and has a size and structure that can adapt to different disposable cup shapes 3, making it easy to adapt to various types of common disposable cups 3 and improving the purchasing convenience of disposable cups 3.

[0021] As a further improved specific implementation, the disposable cup body 3 is a cup made of paper cup, plastic cup or other disposable materials, without the need for a special structure to adapt to the loading of the insulated cup body.

[0022] As a further improved embodiment, the cup holder 4 is integrally formed with the disposable cup body 3, forming a disposable cup body with a special structure adapted to the insulated cup body 1, further improving ease of use. The preferred manufacturing method is to have an outward folded edge at the upper end of the disposable cup body 3, with the upper end of the cup body and the upper end of the outward folded edge together rolled up to form the rolled edge of the cup body, and the outward folded edge and the rolled edge at its lower end forming the cup holder 4; or the cup holder 4 is bonded to the disposable cup body 3.

[0023] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
