Description

Technical Field

[0001] This utility model relates to the field of disposable paper cup technology, and more specifically, to a disposable paper cup that prevents burns. Background Technology

[0002] Disposable paper cups are inexpensive paper cups commonly used in many households and public places for drinking water. They are widely used, but existing paper cups have poor heat insulation, easily causing burns when hot water is poured in. For example, patent CN215099482U discloses a scalding-proof disposable tea cup, comprising a cup body, a side sleeve, a filter screen, a cup bottom, a support ring, threads, and filter holes. The side sleeve is connected to one end of the cup body, the filter screen is located below the cup body, the cup bottom is located on one side of the filter screen, and the support ring is connected to one side of the cup bottom. There are several filter holes, each connected to the filter screen. A first support ring is located below the filter screen. An isolation layer is provided on one side of the filter screen. The side sleeve is cylindrical. A nut-patterned layer is provided on one side of the cup bottom, corresponding to the threads on one side of the cup body. The side sleeve insulates the liquid inside the cup, and the filter screen filters tea leaves through the filter holes.

[0003] When the above-mentioned device is in use, the bottom of the cup is used to hold tea leaves, the support ring supports the side sleeve, the bottom of the cup and the cup body are connected by threads, and the filter screen is supported by the first support ring. However, when the user fills the cup with hot water, the user will hold the outer end of the heat insulation sleeve with their hand. When holding it, the middle of the heat insulation sleeve is prone to shifting inward, which can easily cause the hot water inside the cup to overflow, which can easily cause injury to the user's hand. The device has poor stability in use. Utility Model Content

[0025] This utility model provides a disposable paper cup that prevents burns, such as... Figure 1As shown, the invention includes a disposable paper cup 1, with an inner paper cup layer 6 on its inner side. A top support layer 2 is provided on the upper side of the outer end face of the inner paper cup layer 6, which can reinforce the upper end of the inner paper cup layer 6, thereby effectively increasing the stability of the disposable paper cup 1 when held. A bottom support layer 3 is provided on the lower side of the outer end face of the inner paper cup layer 6, which can reinforce the lower end of the inner paper cup layer 6, increasing the stability of the disposable paper cup 1 when it is filled with hot water, and preventing the bottom of the disposable paper cup 1 from deforming.

[0026] The inner layer 6 of the paper cup has an anti-scalding outer layer 4 in the middle of its outer end face. The outer end face of the anti-scalding outer layer 4 has a heat insulation fin 5. When the disposable paper cup 1 is filled with hot water, the user will hold the outer end face of the heat insulation fin 5. The heat insulation fin 5 reduces the contact area between the user's hand and the disposable cup 1, thereby preventing the hot water inside the disposable paper cup 1 from scalding the user's hand. At the same time, the anti-scalding outer layer 4 can effectively reduce the speed at which heat is transferred from inside the disposable cup 1 to the outside. The thickness of the bottom support layer 3 and the inner layer 6 of the paper cup in the main viewing direction is 0.5mm. The outer end face of the top support layer 2 is adapted to the upper side of the outer end face of the inner layer 6 of the paper cup.

[0027] The heat insulation fins 5 are provided in multiple quantities and are arranged in a ring array outside the center point of the anti-scalding outer layer 4 in the top view direction. The anti-scalding outer layer 4 is made of food-grade wood pulp paper by heating and pressing.

[0028] like Figure 3 and 4 As shown, the inner layer 6 of the paper cup has a winding ring 10 on the outer side of its upper end. The winding ring 10 can increase the firmness of the disposable cup 1 and prevent the disposable cup 1 from bending when held by the user, which would cause the hot water inside the disposable cup 1 to overflow and affect the safety of the user's hands. The lower side of the inner end face of the inner layer 6 of the paper cup has a sealing support layer 7. The inner layer 6 of the paper cup and the sealing support layer 7, and the inner layer 6 of the paper cup and the top support layer 2 are made by hot pressing, which effectively increases the sealing of the connection between the inner layer 6 of the paper cup and the sealing support layer 7, and the inner layer 6 of the paper cup and the top support layer 2, thereby increasing the strength of the paper cup. The inner end face of the inner layer 6 of the paper cup has a seepage-proof coating 11, which can effectively increase the sealing of the disposable paper cup 1 and prevent the hot water inside the disposable cup 1 from leaking. The upper end of the sealing support layer 7 has a bottom layer 9 of the paper cup.

[0029] The bottom of the paper cup 9 is provided with a support pad 8 at its lower end. The bottom of the paper cup 9 and the support pad 8 can effectively increase the stability of the disposable paper cup 1 when it is placed, and prevent the bottom of the disposable paper cup 1 from deforming, thereby increasing the stability and safety of the disposable paper cup 1 during use. The upper opening diameter of the inner layer 6 of the paper cup in the top view direction is larger than the lower opening diameter of the inner layer 6 of the paper cup in the top view direction. The lower ends of the bottom support layer 3 and the sealing support layer 7 are connected and the cross section in the main view direction is set in a U-shape.

[0030] The bottom support layer 3 and the sealing support layer 7 are attached to the lower ends of both sides of the inner layer 6 of the paper cup on adjacent sides in the main viewing direction. The anti-seepage coating 11 is a food-grade PE film, food-grade wood pulp paper, and inner and outer surface PE film. This effectively prevents the wood pulp paper from losing its original stiffness and toughness due to contact with moisture. The outer end of the support pad 8 is attached to the lower end of the bottom layer 9 of the paper cup.

[0031] Finally, it should be noted that: the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
