A type of folding paper cup

Abstract

This invention proposes a folding paper cup, comprising a cup body with a top opening formed by four side panels and a bottom panel. The upper middle part of each of the two opposing side panels is provided with an arc-shaped end face crease, a first oblique crease, and a vertical crease. The first oblique crease extends obliquely downwards from the intersection of the top of the side panel and the vertical crease to the intersection of one end of the arc-shaped end face crease and the side panel. The connecting crease of two adjacent side panels folds inwards, and the combined folding action of the first oblique crease, the arc-shaped end face crease, and the second oblique crease gradually closes the top opening. One side panel has a spout; when drinking, tilting the cup allows liquid to flow out from the spout, avoiding the risk of splashing caused by fully unfolding the cup. When not in use, the cup is folded inwards along the vertical creases on both sides to form a flat shape. The folded state of the paper cup significantly reduces space occupation, facilitating transportation and storage.

Description

Technical Field

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

[0002] Paper cups are widely used in daily life and outdoor activities due to their lightweight, hygiene, and recyclability. However, traditional paper cups have obvious limitations: their fixed structure takes up a lot of space, making them inconvenient to carry and store; the opening design lacks an effective sealing function, making it easy for liquids to spill during movement; and the cup rim needs to be fully exposed when drinking, which not only affects the drinking experience but may also increase the risk of collision in crowded environments. Utility Model Content

[0003] In view of this, in order to solve the problems existing in the technical background, this utility model proposes a folding paper cup. Specifically, it includes the following: A folding paper cup includes a cup body with a top opening formed by four side panels and a bottom panel. The upper middle part of two opposite side panels is provided with an arc-shaped end face crease, a first oblique crease and a vertical crease. The first oblique crease extends obliquely downward from the intersection of the top of the side panel and the vertical crease to the intersection of one end of the arc-shaped end face crease and the side panel. The upper middle part of the other two opposite side panels is provided with an arc-shaped end face crease and a second oblique crease.

[0004] Furthermore, the lower part of the second diagonal crease is located at the intersection of the curved end face crease and the side panel, and the upper part of the second diagonal crease is located at the center of the top of the side panel. Furthermore, one of the side panels has a water outlet.

[0005] Furthermore, the overall shape of the cup is a square platform structure that is wider at the top and narrower at the bottom.

[0006] Furthermore, each of the side panels has an arc-shaped end face crease in its upper middle part, and the two ends of each arc-shaped end face crease coincide with the arc-shaped end face crease of the adjacent side panel.

[0007] The above technical solution has the following beneficial effects: The two adjacent side panels of this invention fold inward at the connecting creases, and in conjunction with the folding action of the first oblique crease, the arc-shaped end face crease, and the second oblique crease, the top opening gradually closes. One side panel has a spout, and when drinking, the cup is tilted so that the liquid can flow out from the spout, avoiding the risk of splashing caused by fully opening the cup. When not in use, the cup can be folded inward along the vertical creases on both sides to flatten it. The folded paper cup can significantly reduce the space occupied, making it convenient for transportation and storage. Attached Figure Description

Detailed Implementation

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] See Figures 1-2 The illustrated folding paper cup consists of four side panels 1 and a bottom panel 7, forming a square-shaped structure that is wider at the top and narrower at the bottom, with an opening 5 at the top. The four side panels 1 employ different crease designs in pairs to achieve the folding function. One pair of opposing side panels 1 has an arc-shaped end face crease 4, a first oblique crease 2, and a vertical crease 3. The arc-shaped end face crease 4 is located in the upper middle part of the side panel 1 and extends in an arc shape to the edge of the adjacent panel. The first oblique crease 2 extends obliquely downwards from the intersection of the top of the side panel 1 and the vertical crease 3 to the point where one end of the arc-shaped end face crease 4 intersects with the side panel 1. The vertical crease 3 is arranged perpendicular to the bottom of the cup. The other pair of opposing side panels 1 has an arc-shaped end face crease 4 and a second oblique crease 8. The second oblique crease 8 extends obliquely upwards from the intersection of the arc-shaped end face crease 4 and the edge of the side panel 1 to the center of the top of that side panel 1. All arc-shaped end face creases 4 maintain a continuous transition at the junctions of adjacent side panels 1.

[0012] Before use, the folded paper cup should be unfolded, with the cup body upright and the top opening 5 fully open to hold the liquid. Figure 1As shown, when the cup needs to be closed, the user can simultaneously press the four side panels 1 inward along the curved end face crease 4. At this time, the first oblique crease 2 and the second oblique crease 8 guide the panels to fold in tandem. The side panel 1 with the first oblique crease 2 will indent inward along the vertical crease 3, while the side panel 1 with the second oblique crease 8 will converge towards the center. As the folding process continues, the tops of the four side panels 1 gradually move closer together, eventually completely closing the cup opening. The spout 6 is located below the curved end face crease 4 corresponding to one of the side panels 1. When drinking, simply tilt the cup, and the liquid will flow out from the spout 6 without fully unfolding the cup opening.

[0013] See Figure 3 and Figure 4 As shown, the folded paper cup is flat, reducing space usage. The paper cup used in this invention is made of the same material as commonly used paper cups on the market.

[0014] The basic principles and main features of this utility model have been described above. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
