[0021] The technical scheme in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments, based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Reference is made to the drawings Figure 1 and the drawings Figure 2 ,

[0023] Embodiment one:

[0024] A combined sealing paper can comprises:

[0025] The can body 1 has an open top;

[0026] The buckle groove 2 is arranged on the can body 1;

[0027] The can cover 3 is buckled on the buckle groove 2 of the can body 1 and completely covers the open top of the can body 1;

[0028] The aluminum foil paper 4 is fixedly arranged on the inner wall of the open top of the can body 1;

[0029] The aluminum foil paper 4 is sealed by being attached to the inner wall of the opening of the can body 1 by ultrasonic heat sealing.

[0030] The paper can further comprises an inner cup 5, the inner cup 5 has a cup wall and a cup edge, the cup wall and the cup edge are integrally arranged, the inner cup 5 is made of aluminum foil paper 4, the outer circle of the cup wall is matched with the inner wall of the can body 1, the cup edge extends to the direction of the buckle groove 2 beyond the can body 1, the aluminum foil paper 4 is attached to the inner cup 5 by ultrasonic heat sealing to realize sealing, and the cup wall of the inner cup 5 is attached to the can body 1 by ultrasonic heat sealing.

[0031] According to the above technical scheme, the inner cup 5 made of aluminum foil paper 4 is added in the paper can, and the inner cup 5 can be completely attached in the paper can by ultrasonic heat sealing or glue sealing, the inverted can cover 3 is tightly clamped with the cup edge part extending into the ring groove, and the aluminum foil paper 4 is sealed by ultrasonic heat sealing, so that the sealing property of the paper can is greatly improved.

[0032] When the can cover 3 is pulled out, the can cover 3 gradually moves away from the aluminum foil paper 4 to form a space with gradually increasing volume, the pressure in the space is negative pressure as the volume gradually increases, and the pressure on both sides of the aluminum foil paper 4 is not equal, so that the aluminum foil paper 4 is easily broken at the center due to the connection between the aluminum foil paper 4 and the inner cup 5, and therefore the following improvement is made.

[0033] Reference is made to the accompanying drawings Figure 3 ,

[0034] Embodiment two:

[0035] A plurality of support plates 6 are fixedly arranged at the opening of the inner cup 5, the support plates 6 are triangular, and the aluminum foil paper 4 is tightly attached to each support plate 6 when the aluminum foil paper 4 is subjected to ultrasonic heat sealing.

[0036] This is an optional implementation to avoid the breakage of the aluminum foil paper 4.

[0037] According to the above technical scheme, the connection surface between the support plate 6 and the aluminum foil paper 4 is used to enhance the connection strength of the inner cup 5 to the aluminum foil paper 4, so that the breakage of the aluminum foil paper 4 caused by the unequal pressure is avoided.

[0038] Reference is made to the accompanying drawings Figure 4 ,

[0039] Embodiment three:

[0040] A counterweight 7 is arranged in the can cover 3, the counterweight 7 is connected to the can cover 3 through a wire 8, and the counterweight 7 is arranged above the aluminum foil paper 4 when the can cover 3 is inverted and buckled on the can body 1.

[0041] This is another optional implementation to avoid the breakage of the aluminum foil paper 4.

[0042] It should be noted that:

[0043] When the can cover 3 is pulled out, the paper can should be placed vertically, and the counterweight 7 should be stably placed on the aluminum foil paper 4.

[0044] The length of the wire 8 should be enough to prevent the counterweight 7 from moving away from the aluminum foil paper 4 when the can cover 3 is pulled out.

[0045] Through the above technical scheme, when the can cover 3 is pulled out, the counterweight 7 is always placed on the aluminum foil paper 4, and its gravity is used to offset the pressure caused by the pressure inequality of the negative pressure, so as to avoid the rupture of the aluminum foil paper 4.

[0046] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
