The rotary opening and closing lid main body includes a rotary button lid and a positioning boss. The rotary button lid and the positioning boss are detachably connected. A plurality of arc-shaped blades are sequentially stacked coaxially and rotatably between the rotary button lid and the positioning boss. The arc-shaped blades are connected with the rotary button lid through the cooperation of a positioning pin and a positioning hole, and are connected with the positioning boss through the cooperation of a convex column and a travel groove. When the rotary button lid is rotated, the arc-shaped blades are unfolded from each other, so that the round hole of the rotary button lid communicates with the through hole of the positioning boss, and the product can be taken out.

[0005] Further, the bottom edge of the positioning boss of the rotary opening and closing lid main body is bonded to the tube body with glue.

[0006] Further, the tube body and the bottom lid are tightly connected by a curling seamer.

[0007] Further, a buckle is arranged on the inner wall of the rotary button lid, and a fixing groove is arranged above the positioning boss. During assembly, the buckle cooperates with the fixing groove to enable the rotary button lid and the positioning boss to be rotatably connected relatively.

[0008] Further, a card strip is arranged inside the rotary button lid. Correspondingly, a card slot is arranged on the edge of the positioning boss. The card strip fits with the card slot to limit the rotation radian of the rotary button lid and fasten the component structure.

[0009] Further, the diameters of the round hole and the through hole are the same.

[0010] Further, the arc-shaped blades are set to 3 with the same size but different heights. The arc-shaped blade I is higher than the arc-shaped blade II, and the arc-shaped blade II is higher than the arc-shaped blade III. After the arc-shaped blades are unscrewed, the angle between any two of the three arc-shaped blades is 120°.

[0011] Further, the positioning hole I on the arc-shaped blade I, the positioning hole II on the arc-shaped blade II, and the positioning hole III on the arc-shaped blade III are respectively sleeved on the positioning pins I, II, and III on the inner surface of the screw-on cap.

[0012] Further, the convex column I below the arc-shaped blade I, the convex column II below the arc-shaped blade II, and the convex column III below the arc-shaped blade III respectively penetrate through the travel grooves I, II, and III on the surface of the positioning boss.

[0013] The beneficial effects of the present utility model are as follows: The present utility model simplifies the traditional nested packaging structure of the upper cover and lower can, simplifies the screw-on cap interface in combination with the opening and closing principle of the iris mechanism. When consumers use it, they only need to rotate the cap to pour out the product, which not only saves the overall packaging cost but also simplifies the steps of using the product and increases the fun of the paper tube packaging.

[0024] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic way, so they only show the components related to the present utility model.

[0025] A rotatable opening and closing cover paper tube as shown in the figure includes a rotatable opening and closing cover main body, a barrel body 11 and a bottom cover 12. The rotatable opening and closing cover main body includes a screw-on cap 1 and a positioning boss 7. The screw-on cap 1 and the positioning boss 7 are detachably connected. A plurality of arc-shaped blades are sequentially stacked coaxially and rotatably between the screw-on cap 1 and the positioning boss 7. The arc-shaped blades are connected to the screw-on cap 1 through the cooperation of positioning pins and positioning holes, and the arc-shaped blades are connected to the positioning boss through the cooperation of convex columns and travel grooves. By rotating the screw-on cap 1, the arc-shaped blades are unfolded from each other, so that the round hole 2 of the screw-on cap 1 communicates with the through hole 8 of the positioning boss 7, and the product can be taken out.

[0026] A snap fastener 22 is arranged on the inner wall of the screw-on cap 1, and a fixed slot 10 is arranged above the positioning boss 7. During assembly, the snap fastener 22 cooperates with the fixed slot 10 to enable the screw-on cap 1 and the positioning boss 7 to be relatively rotatably connected.

[0027] A card strip 21 is arranged inside the screw-on cap 1. Correspondingly, a card slot 9 is arranged on the edge of the positioning boss 7. The card strip 21 fits with the card slot 9 to limit the rotation arc of the screw-on cap 1 and fasten the component structure.

[0028] The arc-shaped blades are set to 3 with the same size but different heights. The arc-shaped blade I 4 is higher than the arc-shaped blade II 5, and the arc-shaped blade II 5 is higher than the arc-shaped blade III 6. After the arc-shaped blades are unscrewed, the included angle between any two of the three arc-shaped blades is 120°.

[0029] The positioning hole I 41 on the arc-shaped blade I 4, the positioning hole II 51 on the arc-shaped blade II 5, and the positioning hole III 61 on the arc-shaped blade III 6 are respectively sleeved on the positioning pin I 111, the positioning pin II 112, and the positioning pin III 113 on the inner surface of the screw-on cap 1.

[0030] The convex post Ⅰ42 below the arc-shaped blade Ⅰ4, the convex post Ⅱ52 below the arc-shaped blade Ⅱ5, and the convex post Ⅲ62 below the arc-shaped blade Ⅲ6 respectively penetrate through the stroke groove Ⅰ71, the stroke groove Ⅱ72, and the stroke groove Ⅲ73 on the surface of the positioning boss 7.

[0031] For the rotary opening and closing lid paper tube of the present utility model, the creative structure mainly focuses on the rotary buckle lid 1, the arc-shaped blades, and the positioning boss 7. The rotary buckle lid 1 is connected to the three arc-shaped blades by three positioning pins. The three arc-shaped blades have the same size and are stacked in a stepped manner around the central axis and rotated in sequence. They are connected to the three stroke grooves of the positioning boss 7 through the convex posts below the blades. The three modules together form the main body of the rotary opening and closing lid.

[0032] The diameter of the circular hole 2 at the center of the rotary buckle lid 1 is the same as that of the through hole 8 at the center of the positioning boss 7 and they are on the same central axis. After being unscrewed, the three blades are arranged in sequence below the lid surface of the rotary buckle lid 1, and the whole paper tube is in a through state.

[0033] The main body of the rotary opening and closing lid is bonded to the barrel body 11 with glue. During production, the paper tube needs to be inverted. After the product is filled, the barrel body 11 and the bottom lid 12 are compacted and sealed by a curling seaming machine.

[0034] Before being unscrewed and used, the case of the present utility model is Figure 1 When being unscrewed and used, it is Figure 2 Consumers only need to unscrew the lid in the direction of the indication arrow 3 on the lid surface to open the blades and pour out the product. The operation is simple, and because its structure is similar to a shutter switch, it is highly interesting.

[0035] Inspired by the above ideal embodiments based on the present utility model, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
