[0038] Combination Figures 1-7 As shown, in some embodiments, the beverage cup holder includes an insulated sleeve 100 and a lifting member 200. The lifting member 200 is disposed on the upper side of the insulated sleeve 100, and the lower end of the lifting member 200 is connected to the upper end of the insulated sleeve 100; wherein, the insulated sleeve 100 and the lifting member 200 together enclose an accommodating space 300 for holding a beverage cup 400.

[0039] The beverage cup holder provided in this embodiment of the invention uses an insulated sleeve 100 and a lifting member 200 to jointly enclose a accommodating space 300 for holding a beverage cup 400. The insulated sleeve 100 can keep the beverage cup 400 warm and insulated, while the lifting member 200 can provide a lifting function. When drinking beverages, the user can hold the insulated sleeve 100 to avoid burns, and at the same time, the insulated sleeve 100 can reduce heat loss from the beverage cup 400. When the user needs to carry the beverage cup 400, they can hold it by the lifting member 200. By using the insulated sleeve 100 and the lifting member 200 together, the beverage cup 400 can be held and kept warm, and the beverage cup 400 can be carried by the lifting member 200, which reduces beverage packaging and carrying costs and reduces environmental burden.

[0040] Optionally, the cross-sectional area of ​​the insulation sleeve 100 gradually increases from bottom to top along the vertical direction. Since most beverage cups 400 are shaped with a wider top and narrower bottom, designing the cross-section of the insulation sleeve 100 to gradually increase from bottom to top allows it to better fit the beverage cup 400. Because most beverage cups 400 have a cup-shaped structure with a wider top and narrower bottom, the insulation sleeve 100 also helps to restrain the beverage cup 400, preventing it from slipping out of the sleeve and further improving the stability of carrying the beverage cup 400.

[0041] Specifically, the insulation sleeve 100 is an inverted, hollow, frustum-shaped structure. This allows the insulation sleeve 100 to better fit the beverage cup 400.

[0042] Optionally, the insulation sleeve 100 has an upper port at its upper end and a lower port at its lower end. When holding a beverage cup 400, the beverage cup 400 is inserted through the upper port, and the lower end of the beverage cup 400 extends out through the lower port. In this way, by using openings at both the upper and lower ends of the insulation sleeve 100, the beverage cup 400 can pass through the insulation sleeve 100 when placed, thus allowing the beverage cup holder to accommodate insulated cups of different heights, reducing the material consumption of the insulation sleeve 100, and lowering costs.

[0043] Optionally, the area of ​​the lower end of the insulation sleeve 100 is nine-tenths of the area of ​​the upper end. This makes the taper of the insulation sleeve 100 relatively small, which can fit most beverage cups 400.

[0044] Combination Figure 2 and Figure 3 As shown, in one embodiment, the lifting member 200 includes an elastic tension sleeve 210 and a handle 220. The elastic tension sleeve 210 is disposed above the insulation sleeve 100, and the lower edge of the elastic tension sleeve 210 is connected to the upper edge of the insulation sleeve 100; the handle 220 is connected to the elastic tension sleeve 210 and is located on the upper side of the elastic tension sleeve 210.

[0045] In this embodiment, the lifting component 200 is divided into an elastic stretch sleeve 210 and a handle 220. The elastic stretch sleeve 210 cooperates with the insulation sleeve 100 to hold the beverage cup 400. The elastic stretch sleeve 210 itself is elastic and can stretch and contract, better adapting to the holding of beverage cups 400 of different heights. The user can lift the elastic stretch sleeve 210 through the handle 220, thereby lifting the entire beverage cup holding sleeve, making it convenient to carry the beverage cup holding sleeve, and thus convenient to carry the beverage cup 400.

[0046] Optionally, the accommodating space 300 is jointly enclosed by the elastic stretch sleeve 210 and the insulating sleeve 100. In this way, by using the insulating sleeve 100 and the elastic stretch sleeve 210 to jointly enclose the accommodating space 300 to hold the beverage cup 400, the length of the accommodating space 300 can be increased. At the same time, with the help of the elastic stretch sleeve 210, it can better accommodate the placement of beverage cups 400 of different heights.

[0047] In one specific embodiment, both the elastic stretch sleeve 210 and the insulation sleeve 100 are made of elastic paper material. This reduces the production cost of the elastic stretch sleeve 210 and the insulation sleeve 100.

[0048] In another specific embodiment, both the elastic stretch sleeve 210 and the insulation sleeve 100 are made of elastic rubber material. This allows the elastic stretch sleeve 210 and the insulation sleeve 100 to have better elasticity, enabling them to deform according to the height and diameter of the beverage cup 400, and better adapt to the holding of beverage cups 400 with different diameters and heights.

[0049] Optionally, the elastic stretch sleeve 210 can be stretched upwards in the vertical direction to change the height of the accommodating space 300. Thus, by stretching the elastic stretch sleeve 210, the height of the accommodating space 300 can be changed. When a relatively tall beverage cup 400 needs to be placed, the user pulls the elastic stretch sleeve 210, causing it to stretch upwards and increasing the height of the accommodating space 300. Through the stretching of the elastic stretch portion, the beverage cup holder can adapt to holding beverage cups 400 of different heights.

[0050] For example, when a user needs to carry a beverage cup 400, the user's hand pulls the handle 220 upwards. At this time, the handle 220 applies an upward pulling force to the elastic stretch sleeve 210, while the beverage cup 400, under its own weight and limited by the insulation sleeve 100, applies a downward pulling force to the elastic stretch sleeve 210, causing the elastic stretch sleeve 210 to be stretched and wrap around the upper part of the beverage cup 400.

[0051] Optionally, the elastic sleeve 210 can spring back to its original position vertically. This way, when the user drinks again while carrying the beverage cup 400, the user no longer needs to apply force to the elastic sleeve 210 through the handle 220. The elastic sleeve 210 can naturally spring back under its own elasticity, eliminating the need for the user to pull down the elastic sleeve 210, reducing the pulling step and improving the user experience.

[0052] For example, when a user needs to drink from the beverage cup 400 again, they only need to put down the beverage cup sleeve. The elastic stretch sleeve 210 automatically springs back downwards, causing the handle 220 to return to its initial state. The user can then hold the insulated sleeve 100 to drink, without having to pull down the elastic stretch sleeve 210. Moreover, the natural rebound of the elastic stretch sleeve 210 eliminates the need for a bagging action when placing the beverage cup 400, resulting in higher packaging efficiency for the beverage cup 400.

[0053] Optionally, the side wall of the elastic stretch sleeve 210 is provided with multiple hollow openings 230. This facilitates the expansion and contraction of the elastic stretch sleeve 210. The multiple hollow openings 230 also allow the elastic stretch sleeve 210 to better rebound downwards when stretched, reducing the material consumption of the elastic stretch sleeve 210 and lowering the production cost of the beverage cup sleeve.

[0054] Optionally, multiple perforations 230 are evenly arranged along the sidewall of the elastic tension sleeve 210. This makes the overall force on the elastic tension sleeve 210 more uniform, less prone to displacement when stretched, and able to spring back to its initial state when it rebounds downward.

[0055] Optionally, when the elastic sleeve 210 is stretched upwards, the multiple openings 230 open; when the elastic sleeve 210 springs back downwards to its original position, the multiple openings 230 close. Thus, when the elastic sleeve 210 is stretched upwards, the multiple openings 230 open, providing the elastic sleeve 210 with the potential energy for rebound. When the elastic sleeve 210 is no longer subjected to the user's pulling force, it can naturally spring back downwards. When the elastic sleeve 210 springs back downwards to its original position, the multiple openings 230 close, reducing the thickness of the elastic sleeve 210 and minimizing the space occupied by the beverage cup sleeve.

[0056] Understandably, the multiple cutouts 230 are telescopic openings cut into the side wall of the elastic stretch sleeve 210. As the stretch length of the elastic stretch sleeve 210 increases, the length of the multiple cutouts 230 also increases. As the elastic stretch sleeve 210 is stretched, each cutout 230 undergoes a deformation process from a flat opening to a round opening and then to an elliptical opening, thereby applying elastic force to the downward rebound of the elastic stretch sleeve 210.

[0057] Optionally, the elastic stretch sleeve 210 and the handle 220 are integrally formed. This makes the elastic stretch sleeve 210 and the handle 220 a single unit, resulting in higher strength. Under frequent use, the connection between the handle 220 and the elastic stretch sleeve 210 is less prone to breakage, thus extending the service life of the beverage cup sleeve.

[0058] Combination Figure 4 As shown, in another embodiment, the lifting member 200 includes a pull ring 500. Multiple pull rings 500 are provided, and the lower ends of each pull ring 500 are connected to the upper end of the insulation sleeve 100.

[0059] In this embodiment, the lifting element 200 consists of multiple pull rings 500. By connecting the multiple pull rings 500 to the insulation sleeve 100, the insulation sleeve 100 can be directly lifted through the pull rings 500, thereby lifting the beverage cup 400. This simplifies the structure of the beverage cup holder and reduces production costs.

[0060] Optionally, multiple pull rings 500 are symmetrically distributed in pairs on both sides of the axis of the insulation sleeve 100. In this way, by symmetrically arranging multiple pull rings 500 in pairs on both sides of the axis of the insulation sleeve 100, the user can lift the beverage cup sleeve by holding the pull rings 500, which improves the stability of the beverage cup 400 when carried.

[0061] For example, two pull rings 500 are provided, symmetrically distributed on both sides of the axis of the insulation sleeve 100. The lower ends of both pull rings 500 are rotatably connected to the upper end of the insulation sleeve 100. When the beverage cup sleeve needs to be carried, the user pulls the two pull rings 500 to a vertical position, and the beverage cup 400 can be carried by the pull rings 500. When it is necessary to drink the beverage during carrying, the two pull rings 500 will fall to the sides of the insulation sleeve 100 under the action of gravity, reducing the space occupied.

[0062] Combination Figure 5 As shown, in one embodiment, the length of the lifting member 200 in the vertical direction is greater than or equal to three times the length of the insulation sleeve 100. Thus, when the length of the lifting member 200 is less than three times the length of the insulation sleeve 100, the length of the lifting member 200 is relatively small, and the lifting member 200 cannot accommodate the relatively large beverage cup 400 for filling and lifting operations. Therefore, the length of the lifting member 200 is set to be greater than or equal to the length of the insulation sleeve 100, so that the length of the lifting member 200 can accommodate the relatively large beverage cup 400 for filling and lifting operations.

[0063] Optionally, when the lifting member 200 includes an elastic stretch sleeve 210 and a handle 220, the length of the elastic stretch sleeve 210 in the vertical direction is greater than or equal to three times the length of the insulation sleeve 100. Thus, when the lifting member 200 includes the elastic stretch sleeve 210 and the handle 220, since the elastic stretch sleeve 210 cooperates with the insulation sleeve 100 to enclose the accommodating space 300 for holding the beverage cup 400, the length of the elastic stretch sleeve 210 in the vertical direction is greater than or equal to three times the length of the insulation sleeve 100, allowing the length of the lifting member 200 to be adapted to the holding and lifting operation of the relatively tall beverage cup 400.

[0064] Specifically, the length of the elastic tension sleeve 210 in the vertical direction is three times the length of the insulation sleeve 100.

[0065] It is understood that in this embodiment of the disclosure, the length of the lifting member 200 in the vertical direction refers to the length of the lifting member 200 when it is fully stretched upward.

[0066] Combination Figure 6 As shown, in another embodiment, in its initial state, the plane containing the elastic stretch sleeve 210 is parallel to the horizontal plane. Thus, when a user holds the insulated sleeve 100 and picks up the beverage cup 400 to drink, the elastic stretch sleeve 210, which is not subjected to lifting force, can block the user's hand, reducing the risk of the beverage cup sleeve slipping off the user's hand and improving the stability of the user holding the beverage cup sleeve while drinking.

[0067] Understandably, the initial state of the elastic tension sleeve 210 means that the elastic tension sleeve 210 is not subjected to an upward pulling force and rebounds to its initial state under its own elasticity.

[0068] Combination Figure 7 As shown, in one embodiment, the insulation sleeve 100 includes a first part 110, a second part 120, and an elastic connecting part 130. The first part 110 and the second part 120 are symmetrically distributed along the axis of the insulation sleeve 100, and their opposite sides are connected by the elastic connecting part 130. Thus, the insulation sleeve 100 is divided into the first part 110, the second part 120, and the elastic connecting part 130. The symmetrical distribution of the first part 110 and the second part 120, connected by the elastic connecting part 130, allows the first part 110 and the second part 120 to move relative to or away from each other, adjusting the distance between them and thereby adjusting the size of the accommodating space 300. This better accommodates beverage cups 400 of different sizes, improving the user experience.

[0069] For example, when the diameter of the beverage cup 400 to be held is large, the first part 110 and the second part 120 can move in opposite directions under the action of the beverage cup 400 when the beverage cup 400 is placed in, thereby increasing the diameter of the accommodating space 300 defined inside the insulation sleeve 100, so as to hold the larger diameter insulated cup.

[0070] Optionally, both the first part 110 and the second part 120 have semi-circular cross-sections. Under the action of the elastic connecting part 130, the first part 110 and the second part 120 always have a tendency to move relative to each other. This allows the first part 110 and the second part 120 to cooperate in enclosing a cylindrical accommodating space 300, better accommodating the beverage cup 400. Under the action of the elastic connecting part 130, the first part 110 and the second part 120 always have a tendency to move relative to each other. When the beverage cup 400 is being held, the first part 110 and the second part 120 can always cover the outer wall of the beverage cup 400, forming a clamping effect, improving the stability when holding and carrying the beverage, and reducing the risk of the beverage cup 400 falling.

[0071] Optionally, the elastic connecting part 130 includes an elastic band. Thus, by connecting the first part 110 and the second part 120 with the elastic band, the first part 110 and the second part 120 always tend to move relative to each other under the tension of the elastic band. This allows for better clamping of the beverage cup 400 when it is placed inside, improving the stability of the beverage cup 400 when carried.

[0072] Optionally, multiple elastic bands are provided, and these elastic bands are evenly distributed between two opposite sides of the first part 110 and the second part 120. Each elastic band connects to both ends of the first part 110 and the second part 120. By evenly distributing multiple elastic bands between the two opposite sides of the first part 110 and the second part 120, the elasticity of the multiple elastic bands allows for a more stable connection between the first part 110 and the second part 120. When holding the beverage cup 400, the first part 110 and the second part 120 provide a relatively greater clamping force, improving the stability of the beverage cup 400 when carried.

[0073] For example, four elastic bands are provided, with two elastic bands provided between the two opposite sides of the first part 110 and the second part 120, and the two elastic bands provided between the two opposite sides of the first part 110 and the second part 120 are symmetrically arranged with respect to the axis of the insulation sleeve 100.

[0074] Optionally, when the lifting member 200 includes an elastic stretch sleeve 210 and a handle 220, the elastic stretch sleeve 210 is woven from multiple elastic strips, and the handle 220 is an elastic ring disposed at the top of the elastic stretch sleeve 210. Thus, in this embodiment of the present disclosure, since the insulation sleeve 100 is composed of a first part 110, a second part 120, and an elastic connecting part 130, the diameter of the cross-section of the insulation sleeve 100 can be changed by the relative or opposite movement of the first part 110 and the second part 120 according to the size of the beverage cup 400. Therefore, by setting the elastic stretch sleeve 210 to be woven from multiple elastic strips, the diameter of the elastic stretch sleeve 210 can also change with the change of the diameter of the insulation sleeve 100 when the first part 110 and the second part 120 move relative or opposite, thus better adapting to the holding of beverage cups 400 of different sizes.

Other embodiments may include structural and other changes. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the order of operation may vary.
