The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

As shown in FIG. 1, the present application provides a disposable bowl cover, which belongs to a fitting of packaged tableware, and is heat-sealed on a disposable bowl of the packaged tableware. The disposable bowl cover comprises a female cover 1, a sub-cover 2, a slice 3 and a release oil layer 5. The female cap 1 includes a flat region 1a, a depressed region 1b depressed with respect to the flat region 1a, and cut holes 1c formed in the depressed region 1b for water filtration. The cut piece 3 is a structure produced when the cut hole 1c is cut out, so it matches the shape of the cut hole 1c and serves to close the cut hole 1 c. The sub-cover 2 is filled in the recessed area 1b and attached (i.e., attached and connected) to the cut-out 3. The sub-cap 2 can fill the depressed area 1b of the main cap 1 to ensure that the outer surfaces of the main cap 1 and the sub-cap 2 look smoother. Locate between sub-lid 2 and female lid 1 from type oil reservoir 5 with the mode of dodging section 3, and be used for bonding sub-lid 2 and female lid 1, can seal the seam between sub-lid 2 and the female lid 1 simultaneously.

Should leave the adhesive strength between oil reservoir 5 and the sub-lid 2 and leave the adhesive strength between oil reservoir 5 and the female lid 1 different to guarantee that the sub-lid 2 can break away from gradually from oil reservoir 5 or carry and break away from female lid 1 gradually from oil reservoir 5 being uncovered. The release oil layer 5 can be made of separate release oil, thermal transfer ink or a mixture of resin oil, an auxiliary agent and color mixing ink, but is preferably made of the release oil disclosed in the Chinese utility model patent document CN113337195A, and has the advantages of good peeling performance, standard hole falling and hole residue, no transfer in a release area and excellent comprehensive performance.

When in use, the user needs to uncover the sub-cover 2 from the main cover 1 and force the sub-cover 2 to carry the cut sheet 3 to gradually open the cutting hole 1c, so that the user can filter hot water out of the packaged tableware through the cutting hole 1c and prevent the hot-pickled food from flowing out of the packaged tableware together with the hot water. In the process of uncovering the sub-cover 2, the release oil layer 5 with low bonding strength is additionally arranged between the sub-cover 2 and the mother cover 1, so that the sub-cover 2 is ensured to be uncovered by a user more easily. Meanwhile, the disposable bowl cover takes waste generated by a cutting process as the slices 3 for plugging the cut holes 1c, so that the heat preservation, the freshness preservation and the like during brewing can be improved, and steam can be prevented from being infected by the release oil layer 5 and polluting hot-pickled food during condensation and falling.

The shape of the cutting hole 1c and the cut piece 3 may be selected from a circle, a polygon, a strip, and the like. However, in order to improve the drainage performance and simultaneously take into consideration the easy processing characteristics, in the present embodiment, the cutting holes 1c and the cut pieces 3 are selected to be strip-shaped, and each include a proximal end and a distal end that is farther from the edge of the female cap 1 than the proximal end. The cutting holes 1c having the proximal and distal ends can reduce the amount of hot water remaining in the packaged tableware, and more safely prevent hot-pickled foods, particularly noodles, from flowing out of the packaged tableware through the cutting holes 1 c.

In this embodiment, the selected edge 2a of the sub-lid 2 near the center of the main lid 1 is fixedly connected to the boundary position of the flat region 1a and the recessed region 1b of the main lid 1, so as to prevent the user from tearing the sub-lid 2 completely off the main lid 1, thereby preventing the user from generating an excessive amount of garbage when using the packaged tableware. Preferably, the cut hole 1c of the bar shape and the cut piece 3 of the bar shape are perpendicular to the selected edge 2a, and the perpendicular bisector of the selected edge 2a passes through the center of the female cap 1. When the user tears the sub-cap 2 along the perpendicular bisector of the selected edge 2a, the cut piece 3 in the form of a strip is more likely to gradually come off the cut hole 1c following the sub-cap 2, and is less likely to be pulled apart. More preferably, the distal end of the cut piece 3 is secured to the distal end of the cut hole 1c at the selected edge 2a, which can avoid the generation of an excessive amount of waste when the user uses the packaged tableware.
