Description

[Detailed Description of the Invention] The present invention relates to a rotation prevention structure for a can lid in which the lid is fitted and fixed to the opening edge of a cylindrical can body.

To fit and secure the lid to the opening edge of the can, a flange is formed on the opening edge of the can, and the peripheral edge of the lid is attached to this flange one by one while rotating the can. Sometimes the lid rotates in relation to the can body. Such misalignment of the lid may cause damage if the can or lid is made of colored steel plate.

The present invention was developed in consideration of these points, and its purpose is to prevent the lid from rotating relative to the can body when fixing the lid to the can body, and to prevent the lid from rotating around the can body. To provide a rotation prevention structure for a can lid that can be securely fixed and does not damage the outer surface.

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows a lid body 1, in which a locking pawl 2 is formed by cutting and raising a portion of the peripheral edge portion used for fixing the lid. On the other hand, as shown in FIG. 2, the cylindrical can body 3 to which the lid body 1 is attached has a flange 4 facing outward that is fixed to the opening edge at one end. A locking hole 5 into which the locking claw 2 is locked is formed by cutting out the locking hole 5 .

When attaching the lid body 1 to the can body 3, the locking claw 2 is inserted into the engagement hole 5 as shown in FIG.
In this state, the peripheral edge of the lid 1 and the flange 4 of the can body 3 are fitted and fixed. Even if the lid body 1 is fixed sequentially while rotating the can body 1 instead of being fixed all at once around the entire circumference, the lid body 1 is fixed to the can body by the engagement between the locking pawl 2 and the engagement hole 5. 3, and the lid body 1 will not rotate with respect to the can body 3 and will not be misaligned.

Here, if there are a plurality of pairs of locking claws 2 and engaging holes 5, the rotation will be more securely prevented. In addition, the shape of the locking pawl 2 may be arbitrary, such as the square pawl shape shown in FIGS. 1 and 4, or semicircular, circular, or trapezoidal shapes as shown in FIGS. be.

As described above, the present invention has a can lid rotation prevention structure in which the peripheral edge of the lid is sequentially fitted and fixed while rotating the can, in which an outward flange is formed on the opening edge of one end of the cylindrical can. , an engagement hole is formed in this flange, and an engagement claw that engages with the engagement hole is cut and raised on the peripheral edge of the lid body that covers one end opening edge of the can, facing the above-mentioned flange, and the engagement claw is cut and raised on the peripheral edge of the flange. Since the peripheral edge of the lid is fixed in place, when the lid is sequentially inserted while rotating the can, the engaging piece of the lid engages with the engaging hole of the can, causing the lid to close. This prevents the lid from rotating and misaligning with respect to the can body, allowing the lid to be securely fixed to the can body, and also preventing damage to the can or lid due to the lid being misaligned. It has a unique effect. In addition, since an engaging hole is formed in the flange of the can body and a locking claw is cut and raised on the peripheral edge of the lid body facing the flange, there are no unnecessary protrusions or holes inside the can body. It does not dry up and does not affect the storage of the components stored inside the can.
