Description

Technical Field

[0001] The utility model relates to the technical field of paper cups, in particular to an anti-spill paper cup. Background Art

[0002] Existing paper cups include a cup body and a cup lid, and are widely used in beverage and coffee shops. When in use, hold the cup body with the left hand. After filling it with liquid, cover the cup lid on the cup body. During the process of covering the cup lid, it is easy to shake hands, or sometimes the cup body needs to be taken to the counter to cover the cup lid. During this process, the liquid level in the cup body is easy to shake and overflow from the cup mouth. Content of the Utility Model

[0003] In order to solve the shortcoming that the existing paper cup is easy to overflow when the cup lid is not covered, the utility model provides an anti-spill paper cup, which can prevent liquid from overflowing.

[0004] To achieve the above object, the utility model adopts the following technical solutions:

[0005] An anti-spill paper cup includes a cup body, a cup lid and a water-blocking edge. The water-blocking edge is an annular elastic structure. The water-blocking edge includes a connecting part and a water-blocking part. The connecting part is tightly attached to the inner circumference of the cup mouth of the cup body along the circumferential direction. The water-blocking part is in the shape of a trumpet with a larger upper part and a smaller lower part. The upper edge of the water-blocking part is fixedly connected to the lower side of the connecting part along the circumferential direction. A card slot that can be inserted into the cup mouth of the cup body is arranged along the circumferential direction on the lower side of the cup lid, and a water outlet is arranged at the edge of the cup lid.

[0006] The paper cup includes an open state and a closed state. When the paper cup is in the open state, the cup body is separated from the cup lid, and there is a gap between the outer side of the water-blocking part and the cup wall of the cup body. When the paper cup is in the closed state, the cup mouth of the cup body is inserted into the card slot, and the side wall of the card slot presses the water-blocking part against the cup wall of the cup body.

[0007] Through the above settings, when the cup lid is not covered, the water-blocking part can prevent liquid from overflowing; after the cup lid is covered, the card slot expands the water-blocking part, so that the liquid inside can smoothly flow out through the water outlet by bypassing the water-blocking part after the cup body is tilted; in addition, after the water-blocking edge is inserted into the card slot, the water-blocking edge basically does not contact the liquid, preventing pollution of the liquid and being more hygienic.

[0008] Furthermore, the paper cup further includes a straw, and the straw can pass through the water outlet.

[0009] Through the above settings, it is convenient to drink through the straw.

[0010] Furthermore, the connecting part is glued to the inner circumference of the cup mouth of the cup body.

[0011] Furthermore, when the paper cup is in the open state, the distance from the lower edge of the water-blocking part to the uppermost side of the cup mouth is less than or equal to 5 cm.

[0012] Through the above settings, the influence of the water-blocking part on the water filling amount is reduced.

[0013] Further, when the paper cup is in the open state, the shortest horizontal distance from the outer periphery to the inner periphery of the water retaining edge is greater than or equal to 2 cm and less than or equal to 3 cm. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 5 It is a schematic view of the closed state of the paper cup of the embodiment.

[0019] Figure 6 It is Figure 5 an enlarged view of part B of. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions of the present utility model will be further specifically described below through embodiments in conjunction with the accompanying drawings.

[0021] As Figures 1 to 6 shown, a spill-proof paper cup includes a cup body 3, a cup lid 4 and a water retaining edge 5. The water retaining edge 5 is an annular elastic structure. The water retaining edge 5 includes a connecting portion 51 and a water retaining portion 52. The connecting portion 51 is circumferentially attached to the inner periphery of the cup mouth of the cup body 3. The water retaining portion 52 is in the shape of a trumpet with a larger upper part and a smaller lower part. The upper edge of the water retaining portion 52 is fixedly connected to the lower side of the connecting portion 51 in the circumferential direction. A card slot 41 that can be snapped into the cup mouth of the cup body 3 is provided on the lower side of the cup lid 4 in the circumferential direction. A water outlet 42 is provided at the edge of the cup lid 4;

[0022] The paper cup includes an open state and a closed state. When the paper cup is in the open state, the cup body 3 and the cup lid 4 are disengaged, and there is a gap between the outer side of the water retaining portion 52 and the cup wall of the cup body 3. When the paper cup is in the closed state, the cup mouth of the cup body 3 is snapped into the card slot 41, and the side wall of the card slot 41 presses the water retaining portion 52 against the cup wall of the cup body 3.

[0023] Through the above settings, when the cup lid 4 is not covered, the water retaining portion 52 can prevent liquid from overflowing; after the cup lid 4 is covered, the card slot 41 expands the water retaining portion 52, so that the liquid inside can smoothly flow out through the water outlet 42 by bypassing the water retaining portion 52 after the cup body 3 is tilted; in addition, after the water retaining edge 5 is snapped into the card slot 41, the water retaining edge 5 basically does not come into contact with the liquid, preventing pollution of the liquid and being more hygienic.

[0024] The cup body of this application is made of paper. The water-blocking edge 5 of this application is made of an elastic material, such as rubber, etc., and the water-blocking edge 5 is integrally formed. When the cup cover 4 is not covered, the paper cup is in an open state, such as Figure 2 shown, the lower edge of the water-blocking part 52 is retracted inward. After filling the cup body 3 with liquid, the liquid level is lower than the lower edge of the water-blocking part 52. At this time, when the hand shakes or walks, after the liquid shakes, the water-blocking part 52 can prevent the shaken liquid from overflowing from the cup mouth. Since the lower edge of the water-blocking part 52 slopes downward, even if the liquid overflows to the upper side of the water-blocking part 52, it can flow back into the cup body 3 under the action of gravity, further preventing the liquid from overflowing. After covering the cup cover 4 on the cup body 3, the paper cup is in a closed state. The cup mouth of the cup body 3 and the water-blocking edge 5 are snapped into the card slot 41. The card slot 41 expands the water-blocking part 52, so that the water-blocking part 52 is closely attached to the cup wall of the cup body 3, such as Figure 5 shown. After tilting the paper cup, the liquid can smoothly bypass the water-blocking part 52 and flow out from the water outlet 42, which is convenient for drinking. In addition, since the water-blocking part 52 is stuck in the card slot 41, the card slot 41 is basically a closed space, and the liquid basically does not enter the card slot 41 and contact the water-blocking part 52, preventing the water-blocking part 52 from contaminating the liquid and improving the hygiene.

[0025] As an implementation, the paper cup further includes a straw, and the straw can pass through the water outlet 42.

[0026] Through the above settings, it is convenient to drink through the straw.

[0027] As an implementation, the connecting part 51 is glued to the inner circumference of the cup mouth of the cup body 3 with glue.

[0028] As an implementation, when the paper cup is in an open state, the distance H from the lower edge of the water-blocking part 52 to the uppermost side of the cup mouth is less than or equal to 5 cm.

[0029] Through the above settings, the influence of the water-blocking part 52 on the water filling amount is reduced.

[0030] As an implementation, when the paper cup is in an open state, the shortest horizontal distance W from the outer circumference to the inner circumference of the water-blocking edge 5 is greater than or equal to 2 cm and less than or equal to 3 cm.

[0031] It should be understood that for those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of this utility model.
