(10) As shown in FIG. 1, FIG. 2 and FIG. 5, in the embodiment, the can cover comprises a cover body 1, and the cover body 1 is circular; the can cover also comprises an indicating system for indicating the opening date of the can; the indicating system comprises a pointer 2 and a plurality of scale lines 3; the scale lines 3 are positioned on the surface of the cover body 1 and are uniformly distributed along the circumferential direction of the cover body 1; the inner end of the pointer 2 is articulated with the middle part of the cover body 1 and can rotate around the axis of the cover body 1, and the outer end of the pointer 2 faces to the scale lines 3.

(11) As shown in FIG. 1-2, in the embodiment, the surface of the cover body 1 is provided with a plurality of bar-type ribs 1a, the bar-type ribs 1a are in the shapes of long bars and are uniformly distributed along the circumferential direction of the cover body 1, the quantity of the scale lines 3 is the same as that of the bar-type ribs 1a, and each scale line 3 is positioned on the surface of the corresponding bar-type rib 1a and extends along the length direction of the corresponding bar-type rib 1a respectively. In the structure, the bar-type ribs 1a are protruded from the surface of the cover body 1 respectively, and thus the user can observe more easily, so that the user can enable the pointer 2 to point to the corresponding date of the scale line 3 more conveniently.

(12) As shown in FIG. 5 and FIG. 7, in the embodiment, the middle part of the surface of the cover body 1 is provided with a cylindrical boss 1b, the inner end of the pointer 2 is provided with a circular fixed ring 2a, and the fixed ring 2a sleeves the boss 1b and can rotate around the boss 1b.

(13) As shown in FIG. 1, FIG. 3 and FIG. 4, in the embodiment, the outer surface of the boss 1b is provided with a plurality of first teeth 1b1, the first teeth 1b1 are uniformly distributed along the circumferential direction of the boss 1b, the inner wall of the fixed ring 2a is provided with a plurality of second teeth 2a1, the second teeth 2a1 are uniformly distributed along the circumferential direction of the fixed ring 2a, the second teeth 2a1 are engaged with the first teeth 1b1, and the quantity of the first teeth 1b1 is the same as that of the bar-type ribs 1a. In the structure, the pointer 2 can rotate only under the effect of external force so as to adjust the angle, but the change of the angle is not linear and is discrete, the adjustment is carried out by the pointer 2 pointing to a certain scale line 3, moreover, the quantity of the first teeth 1b1 is the same as that of the bar-type ribs 1a, so that the pointer 2 can point to one scale line 3 when the pointer 2 rotates at an angle, and the structure enables the adjustment to be accurate and quick and the hand feeling to be comfortable.

(14) Preferably, the quantity of the bar-type ribs 1a, the quantity of the first teeth 1b1 and the quantity of the second teeth 2a1 are thirty-one respectively. The structure is designed according to thirty-one days in one month, the thirty-one scale lines stand for the first day to the thirty-first day respectively, and the pointer 2 can correspond to one date of this month when pointing to one scale line 3.

(15) Certainly, as another embodiment, the structure also can be designed according to seven days in one week, so that seven scale lines 3 stand for Monday to Sunday respectively.

(16) As shown in FIG. 1 or FIG. 5, in the embodiment, the surface of the cover body 1 is marked with FIGS. 1, 5, 10, 15, 20, 25, 30 and 31 along the clockwise direction in sequence respectively, each of the FIGS. 1, 5, 10, 15, 20, 25, 30 and 31 replaces one bar-type rib 1a respectively, there are three bar-type ribs 1a between the FIG. 1 and the FIG. 5, there are four bar-type ribs 1a between the FIG. 5 and the FIG. 10, between the FIG. 10 and the FIG. 15, between the FIG. 15 and the FIG. 20 and between the FIG. 20 and the FIG. 25, the FIG. 30 and the FIG. 31 are arranged adjacently, and the FIG. 31 and the FIG. 1 are arranged adjacently. The structure of the cover body 1 is similar to a dial plate, and after the FIGS. 1, 5, 10, 15, 20, 25, 30 and 31 are marked, the user can determine the date more conveniently, so that the convenience of operation is improved.

(17) As shown in FIG. 1 or FIG. 5, in the embodiment, the outer surface of the boss 1b is provided with a plurality of first flanges 1b2, the first flanges 1b2 are positioned at the upper end of the boss 1b and are uniformly distributed along the circumferential direction of the boss 1b, the fixed ring 2a is positioned between the first flanges 1b2 and the surface of the cover body 1, and the first flanges 1b2 abut against the upper surface of the fixed ring 2a. The first flanges 1b2 play a limiting role on the pointer 2, and can prevent the pointer 2 from being separated from the boss 1b in the rotation process; and moreover, the first flanges 1b2 also play a guiding role on the pointer 2, and can prevent the pointer 2 from shaking in the rotation process, so that the stability of the pointer 2 in the rotation process is higher.

(18) Preferably, the pointer 2 is made of an elastic material. The pointer 2 made of the elastic material is high in flexibility, convenient for angle adjustment and convenient in installation.

(19) As shown in FIG. 5 to FIG. 7, in the embodiment, the bar-type ribs 1a are positioned on the upper surface of the cover body 1 respectively, the cover body 1 is made of the elastic material, the lower surface of the cover body 1 is provided with a plurality of circular bulge loops 1c, and the inner wall of each bulge loop 1c is provided with a second circular flange 1c1 respectively. Each bulge loop 1c is used for being matched and fixed with the periphery of a container opening (for example, the bulge loops 1c sleeve the periphery of the container opening, and a container is a container for filing canned food), and the inner diameters of the bulge loops 1c are different, so that the cover body 1 can be applicable for the peripheries of container openings with different calibers; when the inner diameters of the second flanges 1c1 are slightly smaller than the outer diameter of the periphery of the container opening, the bulge loops 1c sleeve the periphery of the container opening, and the second flanges 1c1 can be extruded to generate certain elastic deformation, so that the second flanges can be tightly clamped onto the peripheries of the container openings, the structure can increase the firmness, connected with the container for filling the canned food, of the cover body 1, and the cover body 1 has a preferable sealing effect for the can.

(20) As shown in FIG. 1 or FIG. 5, in the embodiment, the outer surface of the cover body 1 is provided with a handle 1d, and a through hole 1d1 is formed in the handle 1d. The cover body 1 can be more convenient for the user to open by applying force to the handle 1d.

(21) The embodiments described in the disclosure are provided for the spirit of the disclosure by way of illustration only. Those skilled in the art can perform various modifications or supplementations for the described embodiments or adopt similar manners to replace, but without departing from the spirit and scope of the disclosure.
