The main body engaging element 11 is disposed around the edge of the opening 10. The outer edge wall 12 has at least one recess 120. The guide groove 13 is situated at the at least one recess 120.
As shown in FIG. 1 to FIG. 3, the lid 2 comprises a lid engaging element 20. The lid engaging element 20 corresponds to the main body engaging element 11 for allowing the lid 2 to engage with the main body 1 via the main body engaging element 11 and the lid engaging element 20. The improvement of the lid 2 is characterized in that a wall 21 is disposed at an outer boundary of the lid 2 and in that the wall 21 comprising at least one tilting portion 210.
In one embodiment of the present invention, a location of the at least one tilting portion 210 corresponds to a location of the at least one recess 120 to allow the at least one tilting portion 210 and the at least one recess 120 to contact each other. In addition, the at least one recess 120 and the at least one tilting portion 210 are both arc-shaped.
In another embodiment of the present invention, the quantities of the at least one recess 120 and the at least one tilting portion 210 are plural, and a quantity of the plurality of tilting portions 210 is equal to a quantity of the plurality of recesses 120. The location of each of the tilting portions 210 corresponds to the location of each of the recesses 12, and a distance in between each tilting portion 210 is equal. Furthermore, the guide groove 13, for allowing the content inside the main body 1 to flow out smoothly, is situated at one of the plurality of recesses 120 and is connected to the main body engaging element 11.
Please refer to FIG. 1 to FIG. 3. In this embodiment, a rounded opening 10 is situated at an upper-surface of the main body 1, and an engagement element 11 is disposed at the edge of the opening 10. An outer edge wall 12 is situated at the upper-surface, extending upwardly and comprising three recesses 120 to form a corrugated-shaped appearance of the outer edge wall 12.
As shown in FIG. 1 to FIG. 3, a lower-surface portion of the lid 2 has a lid engaging element 20 that can be engaged with the main body engaging element 11, and the wall 21 is disposed around the outer boundary of the lid engaging element 20.
