In order to illustrate the technical solution of the present invention more clearly, the accompanying drawings that need to be used in the description will be briefly introduced below. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. As far as people are concerned, other embodiments can also be obtained according to these drawings on the premise of not paying creative work.

As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, it is a single-cup embodiment of the present invention.

That is, the upper cover 100 shown in FIG. 1 , FIG. 2 , FIG. 3 , FIG. 4 , and FIG. 5 is used on the single-cup inner holder 200 shown in FIG. 6 .

The upper cover 100 is a piece of material pressed from an environmentally friendly recycled tile slurry material. It is square and formed by pressing a mold. The outer edge of the upper cover 100 extends downward to form a circle of outer sides 1 . There is a circle of downwardly recessed side grooves 2 inside the outer side 1, and a circle of upwardly recessed skirt buckle grooves with openings facing downwards is formed between the lower surface of the outer side 1 and the lower surface of the side groove 2. 3.

The two side walls of the side groove 2 are not perpendicular to the upper surface 4 of the upper cover 100, the inner side wall 21 of the side groove 2 forms an included angle of 60 degrees with the upper surface 4 of the upper cover 100, and the outer side wall of the side groove 2 The upper part 22 of the upper cover 100 forms an included angle of 3 degrees with the upper surface 4 of the upper cover 100, and the lower part 23 of the outer side wall of the side tank 2 forms an included angle of 60 degrees with the upper surface 4 of the upper cover 100. In this way, the side wall of the side tank 2 and the upper surface The upper surface 4 of the cover 100 forms a stacking angle, so that multiple upper covers 100 can be stacked, saving storage and transportation space, reducing the occupied space as much as possible during transportation and stacking, which is convenient for transportation, and it is very convenient to pick up the upper cover 100 , will not stick due to friction.

The lower part 23 of the outer wall of the side tank 2 is bent inward to form a diversion angle of 207 degrees with the upper part 22 of the outer wall of the side tank 2, so that the lower half of the outer wall of the side tank 2 forms a circle of diversion noodle.

In actual use, when the upper cover 100 is placed on the single-cup inner support 200, the process of inserting the outer side wall of the side groove 2 into the single-cup inner support 200 is guided and relatively smooth due to the diversion surface. , 3 sets of skirt buckle grooves are set on the upper edge of the single-cup inner tray 200, so as to finally ensure the tightness of the inner space of the package and achieve the effect of heat preservation.

The side groove 2 is provided with several pairs of upwardly protruding side groove reinforcing ribs 5, and each pair of two side groove reinforcing ribs 5 is symmetrically distributed relative to the geometric center of the upper cover 100, and the two pairs of side groove reinforcing ribs 5 are relatively opposite to the upper cover 100. The geometric center of the circle is evenly distributed. In this way, there are side groove reinforcing ribs 5 in four directions of the square side groove 2 .

The structure of the side groove reinforcing rib 5 is that the bottom of the side groove 2 protrudes upwards to form a side groove reinforcing rib groove 51 opening downward, and the two ends of the side groove reinforcing rib 5 are connected with the upper surfaces of the two side walls of the side groove 2 .
