[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0035] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] As described in the background technology, the thermal insulation and heat preservation performance of paper cups in the related art solutions are poor. For example, hot drinks in paper cups will cool down quickly, and ice cream in paper cups will melt quickly. Moreover, when users hold paper cups, the temperature of hot or cold drinks or frozen foods in the paper cups will also be transmitted to the users' hands through the paper cups, causing problems such as frozen or scalded hands, affecting the user's experience.

[0037] In view of this, the embodiment of the present application aims to provide a thermally insulating paper cup, by providing a cup holder, and bonding the cup body and the cup holder together through a thermally insulating layer, so that the thermally insulating layer is used to improve the thermal insulation performance inside the cup body, reduce the cooling or melting speed of hot or cold drinks or frozen foods, and solve the problem of users' hands being frozen or scalded when holding a paper cup.

[0038] The contents of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the contents of the present application in more detail.

[0040] Please refer to Figure 1-Figure 4 The present embodiment provides a thermal insulation paper cup, including a cup body 100 and a cup holder 200. The cup body 100 is arranged in the cup holder 200. A thermal insulation layer 300 is filled between the cup body 100 and the cup holder 200. The cup body 100 is bonded to the cup holder 200 as a whole through the thermal insulation layer 300.

[0041] Specifically, the cup body 100 of this embodiment can be made of a hard paper material, and the cup body 100 is generally cylindrical or prismatic, preferably cylindrical. A space for accommodating other objects is formed in the cup body 100; the cross section of the cup body 100 can be equal everywhere, or the cross section of the cup body 100 can be gradually increased to expand the capacity of the cup body.

[0042] The cup holder 200 includes at least one opening, so that the cup body 100 can be placed in the cup holder 200. The cup holder 200 can also be made of a hard paper material, or the cup holder 200 can also be made of aluminum foil and other materials. The cup holder 200 is similar in shape to the cup body 100, or the cup holder 200 is adapted to a portion of the cup body 100, for example, it can only be adapted to the side wall of the cup body 100; the cup holder 200 only needs to be able to isolate a portion of the cup body 100 from the external environment, and the specific structure can be set as needed.

[0043] A gap is formed between the cup body 100 and the cup holder 200, and the thermal insulation layer 300 is filled in the gap between the cup body 100 and the cup holder 200. The thermal insulation layer 300 itself has a certain viscosity, so that the cup body 100 and the cup holder 200 are bonded together, so that the cup body 100, the cup holder 200 and the thermal insulation layer 300 form a whole component. When in use, the user can hold the cup holder 200 with his hand to pick up the thermal insulation paper cup. Due to the effect of the thermal insulation layer 300, the temperature of the hot or cold drinks or frozen foods in the cup body 100 will not be directly transferred to the user's hands, thereby solving the problem of frozen or scalding hands. In addition, the thermal insulation layer 300 can also improve the thermal insulation and heat insulation performance of the cup body 100, and reduce the cooling or melting speed of hot or cold drinks or frozen foods.

[0044] From the above description, it can be seen that in this embodiment, a cup holder 200 is provided, and the cup body and the cup holder 200 are bonded together through a thermal insulation layer 300, so that the thermal insulation layer 300 is used to improve the thermal insulation performance of the cup body 100, reduce the cooling or melting speed of hot or cold drinks or frozen foods, and solve the problem of frozen or scalded hands when the user holds a paper cup.

[0045] In a possible implementation, the cup body 100 of this embodiment may include a cup bottom 110 and a cup wall 120 ; the cup holder 200 includes a cup holder side wall 210 , the cup holder side wall 210 overlaps with at least a portion of the cup wall 120 , and the thermal insulation layer 300 is filled between the cup wall 120 and the cup holder side wall 210 .

[0046] That is, in this embodiment, the cup holder 200 is only arranged on the outside of the cup wall 120 of the cup body 100, and the cup holder 200 has two openings arranged opposite to each other, so that the cup holder 200 can be sleeved on the outside of the cup body 100 through any opening. The heat preservation and insulation layer 300 is filled between the cup wall 120 and the cup holder 200, so that the heat preservation and insulation performance of the cup body 100 can be improved to a certain extent, and the cooling or melting speed of hot or cold drinks or frozen foods can be reduced; the cup holder 200 can also solve the problem of freezing or scalding the hands of users when holding paper cups.

[0047] like Figure 1-Figure 3 As shown, in another possible implementation, the cup body 100 of this embodiment includes a cup bottom 110 and a cup wall 120; the cup holder 200 is substantially similar in shape to the cup body 100, and accordingly, the cup holder 200 includes a cup holder bottom wall 220 and a cup holder side wall 210. The cup bottom 110 is disposed on the cup holder bottom wall 220, the cup holder side wall 210 overlaps with at least a portion of the cup wall 120, and the heat preservation and insulation layer 300 is filled between the cup bottom 110 and the cup holder bottom wall 220 and between the cup wall 120 and the cup holder side wall 210.

[0048] That is to say, in this embodiment, the cup holder 200 has an opening opposite to the bottom wall 220 of the cup holder, and the cup holder 200 can be fully covered on the outside of the cup body 100, and the thermal insulation layer 300 is filled between the cup bottom 110 and the bottom wall 220 of the cup holder and between the cup wall 120 and the side wall 210 of the cup holder, thereby further improving the thermal insulation performance of the cup body 100 and reducing the cooling or melting speed of hot or cold drinks or frozen foods; the cup holder 200 can also solve the problem of frozen or scalded hands when the user holds a paper cup.

[0049] Preferably, the cup body 100 in this embodiment further includes an opening 130, which is located on the side away from the cup bottom 110, and a curling edge 140 is provided at the opening 130. The setting of the curling edge 140 can facilitate the user to use the beverage in the cup body 100, and can also facilitate the connection of other components. The cup holder side wall 210 extends to the curling edge 140, so that the heat preservation and insulation layer 300 can be completely filled on the outside of the cup wall 120, so as to improve the heat preservation and insulation performance of the cup body 100.

[0050] Please continue to refer to Figure 3In this embodiment, a plurality of protrusions 211 are formed on the side wall 210 of the cup holder, and the protrusions 211 extend from the cup bottom 110 to the side of the opening 130. The provision of the protrusions 211 increases the friction of the side wall 210 of the cup holder, thereby facilitating the user to hold the cup holder 200. In addition, the protrusions 211 also reduce the contact area between the user's palm and the cup holder 200, thereby reducing the heat conduction between the palm and the cup holder 200, which is useful for further reducing the probability of freezing or scalding the user's hands when holding the paper cup.

[0051] Furthermore, in a plane perpendicular to the cup bottom 110, the projection of the raised portion 211 of this embodiment is in an arc shape, and multiple raised portions 211 are connected to each other to form a wave-like profile. Arranging the raised portion 211 in an arc shape can improve the comfort of the user's palm holding.

[0052] The thermal insulation layer 300 of this embodiment may be a polyurethane foam layer or a silicone layer. Among them, the polyurethane foam layer is formed by food-grade polyurethane foam material (also known as foamed polyurethane or polyurethane foam), which is a polymer material formed by mixing raw materials such as isocyanate and polyol through a specific process formula and reacting and foaming under certain conditions, and has good thermal insulation and heat preservation properties. The silicone layer is formed by food-grade silicone material, which is a highly active adsorption material, an amorphous substance, insoluble in water and any solvent, non-toxic and tasteless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. The silicone layer has good stability and good thermal insulation and heat preservation properties.

[0053] Please continue to refer to Figure 1 and Figure 4 In this embodiment, an aluminum foil cover 400 is also provided on the curling edge 140 of the cup body 100, and the aluminum foil cover 400 is bonded to the curling edge 140, thereby sealing the cup body 100 to prevent the beverage or food in the cup body 100 from contacting the external environment. It can be understood that when the cup body 100 contains food such as ice cream, the aluminum foil cover 400 can be peeled off before use; and when the cup body 100 contains beverages, objects such as straws can be directly inserted into the cup body 100 through the aluminum foil cover 400 during use.

[0054] Furthermore, in order to facilitate opening by the user, an opening portion 410 is provided at one end of the aluminum foil cover 400 of the present embodiment. The opening portion 410 is protruded from the aluminum foil cover 400 , and the user can hold the opening portion 410 to open the aluminum foil cover 400 .

[0055] In summary, the thermal insulation paper cup of this embodiment is provided with a cup holder 200, and the cup body and the cup holder 200 are bonded together through a thermal insulation layer 300, so that the thermal insulation layer 300 is used to improve the thermal insulation performance of the cup body 100, reduce the cooling or melting speed of hot or cold drinks or frozen foods, and solve the problem of frozen or scalded hands when the user holds the paper cup.
