Technical Field

[0001] This utility model belongs to the field of cups, and relates to insulated cups, and in particular to a retractable insulated cup. Background Technology

[0002] A thermos is generally a water container made of ceramic or stainless steel with a vacuum layer. The lid on top helps to slow down the heat dissipation of the liquid inside, thus achieving the purpose of keeping it warm.

[0003] For example, the retractable thermos cup with publication number CN202335682U includes a lid 1, a small inner cup 2, a large inner cup 3, and a cup shell 4 integrated with them. Its features include: the lid 1 and the small inner cup 2 are connected by threads; the outer diameter of the small inner cup 2 is the same as the inner diameter of the large inner cup 3, and it is threaded into the large inner cup 3. The capacity of the cup can be increased by simply rotating the small inner cup 2 out of the large inner cup 3, and the height to which the small inner cup 2 is rotated out is determined by the required capacity; the threaded connections between the lid 1 and the small inner cup 2, and between the small inner cup 2 and the large inner cup 3, ensure good sealing of the cup. This utility model has a simple structure, adjustable volume, and is easy to carry, making it a practical daily consumer product.

[0004] The cup described above can be made more portable by storing the smaller inner cup inside the larger inner cup when traveling. Although the small and large inner cups are connected by threads to increase the sealing effect, there are still gaps between the threads, which pose a certain risk of leakage. Utility Model Content

[0005] This invention provides a retractable thermos cup that can be folded to reduce its size and make it easy to carry.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a retractable thermos cup, including an outer cup and an inner cup that slides inside the outer cup. The inner cup and the outer cup are slidably connected by a slider. The slider is fixedly connected to the outer surface of the inner cup. A waterproof sheet is connected to the top of both the inner cup and the outer cup. When the thermos cup is opened, the waterproof sheet unfolds and covers the gap between the inner cup and the outer cup. The waterproof sheet is elastic and deforms when the thermos cup is opened.

[0007] A further preferred embodiment of this utility model is as follows: several magnetic sheets are fixedly connected to both the waterproof sheet and the inner wall of the inner cup. When the inner cup is stored inside the outer cup, the waterproof sheet folds inward toward the inner cup, and the magnetic sheets on the waterproof sheet attract the magnetic sheets on the inner wall.

[0008] A further preferred technical solution of this utility model is as follows: the inner sidewall of the outer cup is provided with a plurality of sliding grooves that facilitate the sliding of the slider and a fixed groove communicating with the sliding grooves. When the outer cup is slid up and down, the slider slides in the sliding grooves.

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0020] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0021] Figures 1-5As shown, a retractable thermos cup includes an outer cup 2 and an inner cup 1 that slides within the outer cup 2. The inner cup 1 and the outer cup 2 are slidably connected by a slider 4, which is fixedly connected to the outer surface of the inner cup 1. The slider 4 is a rectangular block. The inner sidewall of the outer cup 2 is provided with several grooves 5 to facilitate the sliding of the slider 4 and fixed grooves 7 that communicate with the grooves 5. The fixed grooves 7 and the grooves 5 are perpendicular to each other. When the outer cup 2 slides up and down, the slider 4 slides within the grooves 5. When the slider 4 slides into the fixed grooves 7, the position of the inner cup 1 along the height direction of the outer cup 2 is fixed and the height of the thermos cup is fixed.

[0022] Figures 1-5 As shown, when unfolding the thermos cup in its stored state, the outer cup 2 is pulled outward. At this time, the slider 4 is located in the slide groove 5 and slides towards the fixed groove 7 until the slider 4 and the bottom surface of the slide groove 5 form abutment. At this time, the slider 4 and the fixed groove 7 are aligned. The outer cup 2 is further rotated. As the outer cup 2 rotates, the slider 4 slides into the fixed groove 7. At this time, due to the cooperation between the fixed groove 7 and the slider 4, the range of movement of the inner cup 1 along the height direction of the outer cup 2 can be restricted. At this time, the thermos cup is in the unfolded state for use. Figures 1-5 As shown, the slider 4 and the groove 5 in the above structure cooperate with each other to limit the sliding range between the inner cup 1 and the outer cup 2, and prevent the inner cup 1 and the outer cup 2 from separating when sliding relative to each other. The cooperation between the slider 4 and the fixing groove 7 can limit the outer cup 2 to a certain height after the thermos cup is unfolded, and prevent the outer cup 2 from falling and folding due to gravity.

[0023] Figures 1-5 As shown, several locking blocks 6 are integrally formed on the slider 4. Both the locking blocks 6 and the slider 4 are made of metal. Several slots 8 are provided in the fixing groove 7 to facilitate the locking blocks 6 to be inserted. When the locking blocks 6 are inserted into the slots 8, the outer cup 2 and the inner cup 1 are fixed.

[0024] Figures 1-5 As shown, after the slider 4 slides into the fixing groove 7, the locking block 6 locks into the locking groove 8 as the slider 4 slides, thereby fixing the slider 4 in the fixing groove 7. This design can prevent the outer cup 2 from rotating during use and affect its use, and further fixes the rotation range of the outer cup 2.

[0025] Figures 1-5 As shown, both the card block 6 and the card slot 8 have arc-shaped surfaces, which makes it easy for the card block 6 to be inserted into the card slot 8, thus improving the ease of operation of the thermos cup.

[0026] Figures 1-5 As shown, a groove is provided on the top surface of the inner side of the slide 5 to facilitate the insertion of one of the locking blocks 6. A magnetic block is fixedly connected in the groove. When one of the locking blocks 6 is inserted into the groove, the magnetic block and the locking block 6 are attracted to each other and the inner cup 1 is fixed in the outer cup 2.

[0027] Figures 1-7 As shown, when folding and storing the thermos, rotate the outer cup 2 in the opposite direction. At this time, the locking block 6 separates from the locking groove 8, and the outer cup 2 is released from its fixation. Rotate the outer cup 2 further so that the slider 4 slides out of the fixing groove 7 and into the sliding groove 5. Then slide the outer cup 2 downward until the slider 4 abuts against the top surface of the sliding groove 5. At this time, one of the locking blocks 6 is inserted into the groove and the magnetic block can attract the metal locking block 6, thereby fixing the slider 4. At this time, the thermos is in the storage state, which is convenient to carry. Figures 1-7 As shown, the card block 6 and the magnetic block in the above structure cooperate to fix the slider 4 in the groove 5, thereby preventing the outer cup 2 from sliding and affecting carrying when going out.

[0028] Figures 1-7 As shown, a push plate 9 that can abut against the slider 4 is slidably connected in the fixed groove 7. A spring 10 is fixedly connected between the push plate 9 and the fixed groove 7. When the locking block 6 is inserted into the locking groove 8, the push plate 9 slides away from the sliding groove 5 and the spring 10 deforms.

[0029] Figures 1-7 As shown, this design allows the outer cup 2 to be rotated when folding the thermos cup, causing the locking block 6 to separate from the locking groove 8. At this time, the slider 4 is released from its fixation, and the deformed spring 10 pushes the push plate 9 and the slider 4 to slide into the slide groove 5. The outer cup 2 rotates automatically until the slider 4 slides into the slide groove 5. Due to gravity, the outer cup 2 slides down and the slider 4 slides into the slide groove 5 until the magnetic block attracts the locking block 6. In this design, the push plate 9 and the spring 10 play the role of pushing the slider 4 to automatically reset, so that the thermos cup can be automatically folded after the slider 4 is released from its fixation, improving the convenience of operation.

[0030] Figures 1-7 As shown, the top of both the inner cup 1 and the outer cup 2 are connected to a waterproof sheet 3. Both ends of the waterproof sheet 3 are fixed to the top of the outer cup 2 and the inner cup 1 by means of glue. When the thermos is opened, the waterproof sheet 3 unfolds and covers the gap between the inner cup 1 and the outer cup 2. The waterproof sheet 3 is elastic and deforms when the thermos is opened.

[0031] Figures 1-7 As shown, by setting a water-repellent sheet, when the thermos cup is unfolded, the waterproof sheet 3 is also unfolded, thereby blocking the gap between the outer cup 2 and the inner cup 1. When the thermos cup is filled with water, it can prevent water from leaking out through the gap between the outer cup 2 and the inner cup 1. This design effectively improves the waterproof effect of the thermos cup. Figures 1-7 As shown, when the thermos is folded, the waterproof sheet 3 is in a folded state, which makes it easy to store the thermos.

[0032] Figures 1-7As shown, several magnetic sheets 11 are fixedly connected to both the waterproof sheet 3 and the inner wall of the inner cup 1. When the inner cup 1 is stored inside the outer cup 2, the waterproof sheet 3 folds inward toward the inner cup 1 and the magnetic sheets 11 on the waterproof sheet 3 attract the magnetic sheets 11 on the inner wall.

[0033] Figures 1-7 As shown, when the thermos is folded, the waterproof sheet 3 is folded inward, so that the magnetic sheet 11 on the waterproof sheet 3 is attracted to the magnetic sheet 11 on the inner wall of the inner cup 1, thereby fixing the waterproof sheet 3 to the inner wall of the inner cup 1, preventing the waterproof sheet 3 from shaking when carrying the thermos and affecting its carrying, and further reducing the volume of the thermos when carrying, making it easier to carry.

[0034] Figures 1-7 As shown, the waterproof sheet is made of food-grade silicone. Food-grade silicone has properties such as high temperature resistance, non-toxicity, and good elasticity, which can prevent the waterproof sheet from affecting the normal use of the thermos when it is filled with water.
