Abstract

The invention discloses an easy-opening can, which comprises a top cover, wherein the top cover is provided with a convex part, a sealing part is formed in the convex part, the local part of the sealing part is punched to form an upward convex handle, and the convex part or the connecting part of the convex part and the sealing part is provided with a tearing score. When the can is opened, the handle is toggled, the sealing part is extruded or is applied with force to be broken, then the sealing part is torn along the tearing score, and a water outlet is formed, so the opening is simple and convenient, the additional manufacturing of a pull ring is not needed, and the pull ring is riveted with the pulling part. The easy-opening can has the advantages that the processing is simple, the production cost of the product is reduced, and the market competitiveness is improved.

Example Embodiment

[0031] Reference Figure 1 to Figure 16 , An easy-to-open can, comprising a top cover 1 provided with a raised portion 2 on which a part of the raised portion 2 forms a sealing part 3, and a part of the sealing part 3 is formed by stamping A handle 4 protruding upward, the shape of the handle can be as figure 1 The column shape shown can also be as Picture 9 The button shape shown and so on. The raised part 2 or the part where the raised part 2 and the sealing part 3 are connected is provided with a tearing scratch 5, the handle 4 is deviated from the center of the sealing part 3 and is close to the tearing scratched part, if Without the protrusion 2, when opening, the force applied to the handle will cause the top cover to deform as a whole, making it difficult to open the sealing portion.
[0032] For the first embodiment of the present invention, see Figure 1 to Figure 4 , One side of the top cover is recessed downward in an arc shape, and the other side is an inclined surface inclined to the axis center. The convex portion 2 is located on the inclined surface, so that the top of the sealing portion 3 also forms an inclined surface inclined to the axis center. The sealing portion 3 protrudes upwards, and the tearing scratch 5 is provided at the connection part of the sealing portion 3 and the protrusion 2. After opening, the sealing portion is cylindrical and can be reversely covered back out. Nozzle 6.
[0033] For the second embodiment of the present invention, see Figure 5 to Figure 8 , The top cover is a flat surface, the raised portion 2 and the sealing portion 3 are stamped into an inclined surface inclined to the axis, the sealing portion 3 is recessed downward, and the tearing scratch 5 is provided on the raised portion 2 After opening, the sealing part can be covered back to the water outlet.
[0034] For the third embodiment of the present invention, see Figure 9 to Figure 11 , The top cover is flat, the raised portion 2 and the sealing portion 3 are stamped into a slope inclined to the axis, and the sealing portion 3 is flush with the top of the raised portion 2. The cans of this structure cannot be opened Recap and return to the outlet.
[0035] For the fourth embodiment of the present invention, see Figure 12 to Figure 14 As shown, the protruding portion 2 and the sealing portion 3 are flat surfaces, and the sealing portion 3 is flush with the top of the protruding portion 2, and the can of this structure cannot be closed back to the water outlet after being opened.
[0036] For the fifth embodiment of the present invention, see Figure 15 , Figure 16 As shown, the tearing scratch 5 is an opening line, and the sealing part is connected to the top cover after opening.
[0037] There are two opening methods in the present invention. The first opening method is to pull the handle in the direction of tearing and scratching, and squeeze the edge of the sealing part into the tank. After the sealing part is squeezed, the tearing and scratching near the handle The mark is first broken, and then pulled in the opposite direction, the sealing portion can be torn apart along the tearing mark to form the water outlet 6. The second type of 3 opening method is to pull the handle toward the center. The torn scratches near the handle are first pulled apart, and then continue to apply force until the sealing part breaks along the tearing scratches to form the water outlet 6. The opening is simple, Convenient, there is no need to separately make a pull ring and riveted the pull ring to the open part, the processing is simple, the production cost of the product can be reduced, and the market competitiveness is improved.
