Problems solved by technology

When the opening piece is finally torn off from the remaining loop portion, there is a possibility that a part of the remaining loop portion is bent, the score line is cut irregularly, and even a little bit of the tear-off piece remains on the opening piece or the remaining loop as a protrusion. Therefore, a larger opening force is required in the final stage of pulling the opening piece

Embodiment Construction

[0034] The can end of the present invention is a so-called full opening type can end. A panel portion is provided at the center of the main body portion attached (wrapped around) to the can, and an opening piece is formed by scoring lines so as to occupy most of the panel portion. A protruding piece is attached to a part of the peripheral portion of the opening piece by a rivet. Finger hooks are provided on the tabs. When the finger hook is pulled up, an initial break occurs at a part of the score line, and the score line is cut sequentially from the position where the initial break occurs, and finally the cut along the score line is completed on the entire score line. Produced, the opening piece is removed from the body portion, and the can lid is open.

[0035] That is, the can lid 1 of the present invention includes a main body 2 and a protruding piece 3 . exist figure 1 and figure 2 An example of this is shown in . The main body 2 is a disc-shaped member matching th...

Abstract

[Problem] To provide a can lid made of a steel plate and yet having excellent openability. [Solution] A score line 13 defining and forming an opening piece 12 is formed in a peripheral part of a panelpart 4. A tab 3 is fixed to a part of a peripheral part of the opening piece via an attachment part 9. The tab 3 is provided with: a finger-hooking part 8 positioned on the side closer to the centerof the opening piece 12 than the attachment part 9; and a nose part 10 positioned on the side opposite to the finger-hooking part 8 across the attachment part 9 and on the outer peripheral side of thescore line 13. A portion of the panel part 4 under the nose part 10 serves as a support part 15 supporting the nose part 10 from below. An outer peripheral side bead 14 for enhancing the bending rigidity of the support part 15 is formed in a portion of the panel part 4 on the outer peripheral side of the score line 13.

Description

technical field [0001] The present invention relates to a so-called full-open type can end that is open substantially on the entire surface, and particularly relates to a can end configured to open by breaking a score line by pulling a protruding piece. Background technique [0002] The structure of such a can lid is described in patent documents 1-3. When describing its general structure, a substantially circular score line is formed on the outer peripheral portion of the panel portion, which is a portion inside the wrapping portion of the can. The part divided by this score line becomes an opening piece. A protruding piece is attached to a part of the outer peripheral side of the opening piece with a rivet. The protruding piece is a portion of the handle that first breaks a part of the score line, and then sequentially pulls up the opening pieces to break the score line. Therefore, the front end portion (tab nose) of the tab extends from the rivet to the outer periphera...
