[0020] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0021] Example 1:

[0022] like Figure 1 As shown, a high-strength paper cup includes: an outer cup body 10 and an inner cup body 20 embedded within the outer cup body 10; the outer cup body 10 and the inner cup body 20 are bonded together by long fiber pulp; both the outer cup body 10 and the inner cup body 20 have a corrugated structure; the outer cup body 10 is coated with a water-based waterproof coating on its outer side.

[0023] The high-strength paper cup adopts a double-layer cup structure with an inner cup body 20 embedded in an outer cup body 10. The lamination technology can effectively increase the strength of the cup. At the same time, the outer cup body 10 and the inner cup body 20 are bonded together with long fiber pulp. The long fiber pulp has good tear resistance, which can increase the structural strength of the cup. Moreover, both the outer cup body 10 and the inner cup body 20 adopt a corrugated structure. The corrugated structure can effectively disperse stress and increase structural strength.

[0024] The outer cup body 10 is coated with a water-based waterproof coating, which can effectively improve the waterproof effect of the cup. Moreover, the outer cup body 10 coated with the water-based waterproof coating can increase the thickness of the outer cup body 10, thereby increasing the structural strength of the entire paper cup.

[0025] like Figure 2As shown, the outer cup body 10 comprises an outer cup bottom 11, an outer cup body 12 arranged on the outer cup bottom 11, and a clamping head 13 arranged on the outer cup body 12; the outer cup body 12 is of a corrugated structure; the clamping head 13 comprises a half ring 131 connected with the outer cup body 12, an extension segment 132 arranged on the half ring 131, and a gap 133 arranged between the extension segment 132 and the outer cup body 12; the inner cup body 20 comprises an inner cup bottom 21, an inner cup body 22 arranged on the inner cup bottom 21, and a clamping hole 23 arranged on the inner cup body 22; the outer cup body 10 is connected with the inner cup body 22 by embedding the clamping head 13 into the clamping hole 23; the inner cup body 22 is of a corrugated structure; the corrugated direction of the outer cup body 12 is opposite to that of the inner cup body 22, and after the inner cup body 22 is embedded into the outer cup body 12, the corrugations of the two form a wave structure.

[0026] The clamping head 13 comprises the half ring 131 and the extension segment 132, and there is the gap 133 between the extension segment 132 and the outer cup body 12; the half ring 131 is of a certain toughness, and during the process of inserting the clamping head 13 into the clamping hole 23, in order to match the caliber of the clamping hole 23, the half ring 131 will be reduced, and at the same time, the extension segment 132 will be close to the outer cup body 12, and after the clamping head 13 is inserted into the clamping hole 23, the half ring 131 will restore to the original state by virtue of the toughness and tightly adhere to the clamping hole 23.

[0027] The corrugated direction of the outer cup body 12 is opposite to that of the inner cup body 22, and after the inner cup body 22 is embedded into the outer cup body 12, the corrugations of the two form a wave structure; the wave structure greatly increases the structural strength of the paper cup, and when hot water is poured into the paper cup, not only two layers of paper are interposed between the hot water and the palm, but also air in the wave crest, which can effectively prevent the palm from being scalded by the hot water.

[0028] The basic principle and main features of the present application and the advantages of the present application are shown and described above, and it is obvious for those skilled in the art that the present application is not limited to the details of the above-mentioned exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
