Abstract

(57) [Abstract] [Purpose] The top of the can has a large opening so that the contents of the can can be easily taken out, and the cut part is not separated from the can lid and its disposal is not troublesome. . [Structure] A kerf 1a formed on the peripheral edge of the can lid 1 is formed in a circular shape over almost the entire circumference, leaving a non-kerf part 1b in a part thereof, and the end of the kerf 1a is provided at the center of the non-kerf part 1b. The feature is that the auxiliary groove 1c is formed along the connecting line shape.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a can lid such as a food can or a drinking water can.

[0002]

[Prior art]

 A conventional can lid is attached to a cylindrical can main body as shown in JP-A-49-101192, and a kerf for opening is formed over the entire circumference along the peripheral edge. It is known that the unfolding picking piece is attached. In this can lid, by lifting the ring side of the knob piece, the tip end on the opposite side of the ring portion abuts the can lid and is easily cut from the kerf in the vicinity thereof, and then the knob piece is pulled. By stretching, all the kerfs are cut and removed.

[0003]

[Problems to be solved by the device]

 However, such a can lid is completely separated from the can lid by the part that has been cut by the kerf, so the separated part should be left in one hand or discarded or placed in another place. There was the inconvenience of having to retrieve the contents later.

[0004]

[Means for Solving the Problems]

 The present invention has been made in order to solve such a problem, and is mounted on a cylindrical can body (2) and is formed along a peripheral edge of an opening cut groove (1a). In the metal can lid (1) to which the unsealing knob piece (3) is attached, the cut groove (1a) is formed in a circular shape over substantially the entire circumference, leaving a non-cut groove portion (1b) as a part, A metal can lid characterized in that an auxiliary groove (1c) is formed along the line connecting the ends of the kerfs (1a) at the center of the non-kerf (1b). is there.

[0005]

[Action]

 In such a can lid (1), the tip of the knob piece (3) is brought into contact with the peripheral edge of the can lid (1) by being lifted, and is cut from the kerf (1a) in the vicinity thereof. The cutting of the kerf (1a) progresses by pulling (3), but it stops at the end, and when the knob piece (3) is further pulled, the cut part moves between the ends of the kerf (1a). With the help of the auxiliary groove (1c) at the connecting line as a boundary, it is easily bent to open at an angle greater than the vertical, and the top surface opens greatly, and the cut part is separated from the can lid (1). It will be left untouched.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. The can lid 1 is made of aluminum, and its peripheral edge is wound around the upper end of a cylindrical can body 2. A kerf 1a is formed along the peripheral edge of the can lid 1. The cut groove 1a is formed in a circular shape over substantially the entire circumference, leaving a non-cut groove portion 1b in part. A linear auxiliary groove 1c is formed in the central portion of the non-cut groove portion 1b along a line connecting the ends of the cut groove 1a. An opening knob piece 3 of the cut groove 1a is attached to the can lid 1 at a position opposite to the non-cut groove portion 1b. The knob piece 3 has a ring portion 3a and a kerf breaking tip 3b. In such a can lid 1, when the ring portion 3a of the knob piece 3 is lifted, the cutting groove breaking tip 3b comes into contact with the peripheral edge portion of the can lid 1 and is cut from the cutting groove 1a. The cutting of the kerf 1a progresses by pulling the piece 3, but stops at the end thereof. Further, when the knob piece 3 is pulled, this cut portion is easily bent with the help of the auxiliary groove 1c at the line connecting the ends of the cut groove 1a as a boundary, and opens at an angle larger than the vertical, The upper surface is largely opened, and the cut portion remains in the can lid 1 without being separated. Therefore, the contents can be taken out from the top opening as easily as before, and the contents can be taken out while holding the cut part in one hand or discarding or placing it in another place. There is no need for it, and the disposal thereof is trouble-free.

[0007]

[Effect of device]

 According to the present invention, it is possible to provide a can lid which has a large opening on the top of the can so that the contents of the can can be easily taken out, and the cut portion is not separated from the can lid and the disposal thereof is not troublesome. it can.
