AI Technical Summary
When pulling up the lid of an existing aluminum can, long fingernails or big fingers can easily apply too much force, causing discomfort. In particular, the pull rings on small-capacity aluminum can lids are small and difficult for adults or girls to open easily.
A novel can lid is designed, comprising a metal lid and a plastic lid. The metal lid has a recessed moving groove, and the plastic lid has a fixed triangular top block. By rotating the plastic lid, the top block is used to lift the pull ring, which is then fixed to the groove between the plastic lid and the can, reducing the opening force. Tear seams and reinforcing plates are provided on the metal lid to improve stability.
It enables easy opening of the can lid without inserting a fingernail into the bottom of the pull ring, reducing the effort required to open and the risk of scratching fingers. It is suitable for all hand shapes, especially consumers with long fingernails or large fingers. It also requires minimal modification, is low in cost, and is applicable to various sizes of cans.

[0005] To achieve the above object, the utility model provides the following technical scheme: a pop can cover with novel pull ring device, which comprises a metal cover and a plastic cover, the surface of the metal cover is provided with an inner recessed moving groove on one side, the plastic cover is fixed with a top block at a position corresponding to the moving groove, the top block is triangular, and the thickness of the top block gradually increases from left to right.
[0006] Through the above technical scheme, consumers need not insert nails into the bottom of pull ring, and only need to rotate plastic cover to easily push up pull ring by top block, especially for adults with long nails or large fingers, and solve the problem of labor and damage to nails in opening traditional pull ring.
[0007] Further, the inner wall of the plastic cover is provided with a clamping groove clamped with the pop can, the plastic cover is clamped and fixed with the clamping ring of the outer periphery of the pop can through the clamping groove, and the inner diameter of the plastic cover is the same as the outer diameter of the pop can.
[0008] Through the above technical scheme, the annular clamping groove is arranged on the inner wall of the plastic cover, the position is accurately corresponding to the clamping ring of the outer periphery of the pop can, the plastic cover is covered on the pop can, and is pressed downward, so that the clamping groove is completely engaged with the clamping ring, the inner wall of the clamping groove is tightly combined with the outer edge of the clamping ring by the material elasticity, and the stable connection of upper and lower is formed.
[0009] Further, a tear seam is embossed under the surface of the metal cover, and a tearable tab is formed in the tear seam.
[0010] By adopting the technical scheme, the tear seam reduces the tearing strength of the tearable tab, and consumers can easily open it without effort.
[0011] Further, a pull ring is arranged above the surface of the metal cover, a pull ring opening is arranged in the middle of the pull ring, a pressing part is arranged at the bottom end of the pull ring, and a reinforcing tab is fixed on the pressing part.
[0012] By adopting the technical scheme, the reinforcing tab significantly improves the tensile and bending resistance of the bottom end of the pull ring by increasing the cross-sectional area, thereby avoiding breakage during opening.
[0013] Further, the pressing part and the tearable tab are fixedly connected through a fixing part.
[0014] By adopting the technical scheme, the pulling force of the pull ring is directly transmitted to the tearable tab, and the consistency of the tearing path is improved.
[0015] Further, the outer periphery of the pull ring is arranged in a circular arc shape.
[0016] Further, the plastic cover and the top block are an integral structure, and the plastic cover is rotatable on the top of the easy-open can.
[0017] By adopting the technical scheme, the plastic cover is made of food-grade plastic and is formed by an injection molding process, covering the opening at the top of the easy-open can.
[0018] In summary, the utility model mainly has the following beneficial effects:
[0019] 1. The utility model discloses a movable groove is designed on the metal cover, a top block is added on the plastic cover, when using, the consumer holds the outside of the plastic cover with the palm, rotates counterclockwise, makes the top block rotate in the movable groove, because one end of the top block has no thickness, can be very easily rotated to one side of the pull ring, along with the top block gradually moving, the top block can lift the pull ring, instead of the action of inserting the nail into the bottom of the pull ring and prying, it is very convenient for the consumer to open the tearable tab subsequently, and the opening action is simple and is beneficial to use.
[0020] 2. The utility model discloses a movable groove is added on the metal cover, a top block is added on the plastic cover, and the change to the original can cover technology is very small, therefore, only needs to add a little special mould to realize technical upgrading, significantly reduces the equipment investment and the reform cost, increases the user satisfaction through the slight change, improves the sales volume.
