Technical Field

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

[0002] With the fast pace of life, disposable paper cups have become an indispensable consumable item in daily life due to their convenience and low cost. They are widely used in catering, office, and home settings, mainly for holding liquids such as water, beverages, and coffee.

[0003] Existing disposable paper cups are usually single-layered paper structures. When filled with hot water or hot drinks, the temperature on the outside of the cup rises rapidly, and users are easily burned when holding it. They need to be paired with a cup sleeve. Paper cups can only serve the basic function of holding liquids and cannot meet the diverse needs of users such as brewing traditional Chinese medicine and filtering impurities, making them inconvenient to use.

[0004] Therefore, this utility model proposes a disposable paper cup. Utility Model Content

[0005] Therefore, in order to overcome the problem that common disposable paper cups are usually single-layer paper structures, the temperature of the outer surface of the cup will rise rapidly when hot water or hot drinks are poured in, and users are easily burned when holding them, so an extra cup sleeve is required. Paper cups can only play the basic role of holding liquids and cannot meet the diverse needs of users such as brewing Chinese medicine and filtering impurities, which makes them inconvenient to use.

[0006] The technical solution of this utility model is as follows: a disposable paper cup, including a cup body, a cup bottom, a cup mouth, a detachable filter structure, and a graduated transparent strip. The cup bottom and the cup mouth are respectively located at the lower end and the upper end of the cup body, and the cup bottom and the cup mouth are fixed to the cup body by a hot pressing process. The detachable filter structure is movably installed in the lower part of the cup body, and a cavity is formed between the detachable filter structure and the cup bottom. The graduated transparent strip is located on the cup body and is set along the height direction of the cup body.

[0007] Preferably, the cup body includes a middle heat insulation layer, a waterproof inner layer, and a paper outer layer, which are sequentially bonded together from the inside out, and the middle heat insulation layer adopts a honeycomb structure.

[0008] Preferably, a thermochromic layer is provided on the outer surface of the paper outer layer, and the outer surface of the thermochromic layer is provided with an anti-slip embossed texture.

[0009] Preferably, the bottom of the cup includes a waterproof layer, a buffer layer, and a load-bearing layer, which are sequentially attached from top to bottom.

[0010] Preferably, the lower end of the bearing layer is provided with a groove, and the bottom of the bearing layer is provided with anti-slip texture, and an annular reinforcing rib is fixedly installed on the top of the groove.

[0011] Preferably, the detachable filter structure includes an annular support ring, a fine filter screen, and support rods. The edge of the annular support ring is inclined and abuts against the inner wall of the cup. The fine filter screen is installed at the center of the annular support ring. Three support rods are provided and fixedly installed below the fine filter screen. The three support rods are arranged in a triangular pattern.

[0012] The beneficial effects of this utility model are: 1. This disposable paper cup features a three-layer structure: a transparent measuring strip, a middle heat-insulating layer, a waterproof inner layer, a paper outer layer, and a thermosensitive color-changing layer. The heat-insulating layer, waterproof inner layer, and paper outer layer enhance the cup's structural strength. The middle heat-insulating layer, made of foamed material, effectively insulates against heat loss, maintaining the temperature of hot drinks for an extended period. The transparent measuring strip allows for easy monitoring of the water level while pouring, ensuring precise control over the amount of water poured. The thermosensitive color-changing layer is a special coating that changes color according to temperature.

[0019] Please see Figures 1-6This utility model provides a technical solution: a disposable paper cup, including a cup body 1, a cup bottom 2, a cup mouth 3, a detachable filter structure 4, and a graduated transparent strip 5. The cup bottom 2 and the cup mouth 3 are respectively located at the lower end and the upper end of the cup body 1, and the cup bottom 2 and the cup mouth 3 are fixed to the cup body 1 by a hot pressing process. The detachable filter structure 4 is movably installed in the lower part of the cup body 1, and a cavity is formed between the detachable filter structure 4 and the cup bottom 2. The graduated transparent strip 5 is set on the cup body 1, and the graduated transparent strip 5 is set along the height direction of the cup body 1.

[0020] The cup bottom 2 and cup mouth 3 are connected to the cup body 1 using a hot-pressing process, which strengthens the joint between the cup body 1 and the cup bottom 2 and cup mouth 3, preventing liquid leakage. The graduated transparent strip 5 makes it easy to observe the water volume when pouring water, strictly controlling the amount of water poured into the cup. The detachable filter structure 4 is placed at the bottom of the paper cup, and the cavity between it and the cup bottom 2 can hold Chinese medicine, realizing the brewing of Chinese medicine and enjoying hot water containing Chinese medicine ingredients. The cup mouth 3 adopts a double-layer rolled edge structure, and a flexible sealing ring is provided at the rolled edge. When two paper cups are stacked, a gap is formed to prevent vacuum adsorption from causing adhesion.

[0021] The cup body 1 includes a middle heat insulation layer 11, a waterproof inner layer 12, and a paper outer layer 13. The waterproof inner layer 12, the middle heat insulation layer 11, and the paper outer layer 13 are sequentially bonded together from the inside out, and the middle heat insulation layer 11 adopts a honeycomb structure.

[0022] The middle heat insulation layer 11 is made of foam material, the waterproof inner layer 12 is made of polylactic acid waterproof coating, and the paper outer layer 13 is made of biodegradable cardboard. The cup body 1 adopts a three-layer structure, which enhances the structure of the cup body 1 and can effectively insulate heat, effectively slow down heat loss, and maintain the temperature of hot drinks for a longer period of time, reducing the risk of scalding.

[0023] A thermochromic layer 14 is provided on the outer surface of the paper outer layer 13, and the outer surface of the thermochromic layer 14 is provided with an anti-slip embossed texture.

[0024] When the temperature inside the cup exceeds 45°C, the color of the outer wall of the thermochromic layer 14 changes from light to dark, alerting the user to the heat. The anti-slip embossed texture increases the anti-slip performance, allowing the user to grip the paper cup better.

[0025] The cup bottom 2 includes a waterproof layer 21, a buffer layer 22, and a load-bearing layer 23, which are sequentially attached from top to bottom.

[0026] The bottom of the cup has a three-layer structure, which enhances the paper cup's load-bearing capacity, prevents deformation under pressure, and effectively prevents the paper cup from deforming due to thermal expansion and contraction when filled with hot drinks.

[0027] The lower end of the bearing layer 23 is provided with a groove 24, and the bottom of the bearing layer 23 is provided with anti-slip texture. A ring-shaped reinforcing rib 25 is fixedly installed on the top of the groove 24.

[0028] The groove 24 here, together with the ring reinforcing rib 25, enhances the pressure resistance of the cup bottom 2, making it more durable and suitable for long-term use when holding hot drinks.

[0029] The detachable filter structure 4 includes an annular support ring 41, a fine filter screen 42, and support rods 43. The edge of the annular support ring 41 is inclined and abuts against the inner wall of the cup body 1. The fine filter screen 42 is installed at the center of the annular support ring 41. There are three support rods 43, and the support rods 43 are fixedly installed below the fine filter screen 42. The three support rods 43 are arranged in a triangular pattern.

[0030] The removable filter structure 4 placed inside the paper cup forms a cavity between itself and the bottom 2 of the cup. This cavity can be used to hold Chinese medicine or tea. Hot water is poured into the paper cup and comes into contact with the Chinese medicine or tea to obtain a hot drink containing Chinese medicine or tea ingredients.

[0031] Working principle: See Figures 1-3 As shown, hot water is poured into a paper cup. The amount of water can be observed through the graduated transparent strip 5 while pouring, and the amount of water poured into the cup can be strictly controlled. The thermosensitive color-changing layer 14 is a special coating that can change color according to temperature changes. When the temperature inside the cup is higher than 45℃, the color of the thermosensitive color-changing layer 14 changes, and the color of the outer wall of the paper cup changes from light to dark. Users can judge the water temperature by the color, so as to avoid scalding the user by drinking water that is too hot.

[0032] See Figure 2 and Figure 6 As shown, users can install the detachable filter structure 4 according to their needs. If they need to brew Chinese medicine or tea, they can first add the Chinese medicine or tea to the bottom of the paper cup, and then put the detachable filter structure 4 into the paper cup. The lower end of the support rod 43 contacts the bottom 2 of the cup, covering the Chinese medicine or tea. After pouring in hot water, the hot water passes through the filter mesh 42 and comes into contact with the Chinese medicine or tea, resulting in a hot drink containing Chinese medicine or tea ingredients.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
