For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figure 1 and Figure 2As shown, the utility model provides a packaging can sealed with aluminum foil, comprising a can body 1, a can cover 2 is arranged on the top of the can body 1, a discharge area for convenient powder pouring is arranged on the surface of the can cover 2, a protrusion 5 is arranged at the edge of the discharge area, the protrusion 5 is arranged to be inclined outward, an aluminum foil 6 is attached to the surface of the can cover 2, the protrusion 5 is in close contact with the aluminum foil 6, and the aluminum foil 6 is fixed under the mutual force, so as to realize the positioning of the aluminum foil 6, the moisture-proof and airtight performance of the aluminum foil 6 is much better than that of plastic paper, the aluminum foil 6 can ensure the sealing of the powder in the packaging can, and there is no need to install a plastic cover separately, thereby reducing the production cost; at the same time, ear straps 7 are symmetrically arranged at both ends of the aluminum foil 6, and the ear straps 7 are attached to the side wall of the can body 1, and the ear straps 7 can provide a fulcrum when the aluminum foil 6 is peeled off, thereby improving the convenience of use.

[0027] In order to further improve the performance of the packaging can, the discharging area of ​​this embodiment specifically includes a slow discharging area and a fast discharging area. A number of small discharging holes 3 are arranged at intervals in the slow discharging area, and a large discharging port 4 is arranged in the fast discharging area. The diameter of the large discharging port 4 is larger than the diameter of the small discharging holes 3. When a small amount of discharging is required, the aluminum foil 6 in the slow discharging area can be peeled off, and the powder in the packaging can will be sprinkled out at a uniform speed through the small discharging holes 3; when a large amount of discharging is required, the aluminum foil 6 in the fast discharging area can be peeled off, and the powder in the packaging can will be quickly sprinkled out through the large discharging port 4.

[0028] Most of the existing discharge holes are cylindrical. When used for discharging large-particle powder, the discharge holes of this structure are often blocked. In order to avoid this problem, refer to Figure 4 In this embodiment, the apertures of the small discharge hole 3 and the large discharge port 4 are gradually increased from the inside to the outside, and extend to the surface of the tank cover 2 to form a protrusion 5, so that the cross-section of the small discharge hole 3 and the large discharge port 4 is an inverted trapezoidal structure. The inverted trapezoidal structural design can guide the powder to discharge quickly, and effectively avoid the situation where the powder blocks the discharge hole; and the setting of the protrusion 5 can form a concave and convex surface on the surface of the tank cover 2. When the aluminum foil 6 is attached to the surface of the tank cover 2, the aluminum foil 6 will be subjected to the interaction force of the protrusion 5, which can effectively prevent the aluminum foil 6 from shifting.

[0029] In order to further improve the positioning of the aluminum foil 6, the can cover 2 between the slow discharge area and the fast discharge area is recessed downward to form a fixing groove 8, and a fixing strip 9 is fixedly provided at the bottom of the aluminum foil 6 corresponding to the position of the fixing groove 8. The fixing strip 9 is embedded in the fixing groove 8 to strengthen the fixation of the aluminum foil 6.

[0030] like Figure 3 As shown, folding lines 10 are provided on both sides of the aluminum foil 6 corresponding to the fixing strip 9. The folding lines 10 can separate the slow discharging area from the fast discharging area. Under the guidance of the folding lines 10, the aluminum foil 6 can separately uncover the slow discharging area or the fast discharging area.

[0031] Preferably, a self-adhesive layer is provided at the bottom of the ear strap 7 of the present embodiment, and the ear strap 7 can be adhered to the side wall of the tank body 1 through the self-adhesive layer. When the aluminum foil 6 needs to be uncovered, the user can uncover the aluminum foil 6 by pulling the ear strap 7, and the ear strap 7 can be re-adhesive to the side wall of the tank body 1 after use.

[0032] like Figure 5 As shown, as a preferred embodiment of the present embodiment, the aluminum foil 6 of the present embodiment includes an outer aluminum foil layer 61, an elastic rubber layer 62 and an inner aluminum foil layer 63. The elastic rubber layer 62 is located between the outer aluminum foil layer 61 and the inner aluminum foil layer 63. When the powder in the packaging can is not fully used and needs to be stored, the inner aluminum foil layer 63 can be pressed and attached to the surface of the can cover 2, which can effectively prevent the powder inside the packaging can from getting damp. At the same time, the elastic rubber layer 62 is added to the aluminum foil 6 of the present embodiment. When the surface of the aluminum foil 6 is wrinkled by the force, the elastic rubber layer 62 has good elastic recovery force, so the elastic potential energy increases during the wrinkling process. When the external force disappears, the elastic potential energy is released, thereby driving the aluminum foil 6 to return to flatness, so that the aluminum foil 6 can be reused many times, thereby improving the use efficiency of the aluminum foil 6.

[0033] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention. In addition, some terms used in the specification and claims of this application are not restrictive, but are only for the convenience of description.
