Definitions

  • FIG. 1 is a cross-sectional view showing the configuration of the can container 100 according to the embodiment of the present invention.
  • FIGS. 2 to 4 are enlarged cross-sectional views showing a can lid 1 and a can body 101 of the can container 100.
  • FIG. 2 shows a state before opening the can lid 1
  • FIG. 3 shows a state during opening the can lid 1
  • FIG. 4 shows a state after opening the can lid 1.
  • the panel portion 21 is formed in a disk shape.
  • the panel portion 21 includes a score line 31, a rivet portion 32, an auxiliary score line 33, a protection portion 34, and a finger insertion concave portion 35.
  • the panel portion 21 may also have a display portion 36 or the like such as braille for displaying the content of the can container 100. Further, the panel portion 21 may have a convex portion or a concave portion for product identification, design, reinforcement, or the like.
  • the score line 31 is broken by an opening operation of the tab 12.
  • the score line 31 creates an opening portion of the can lid 1 in the panel portion 21.
  • the score line 31 surrounds a region which becomes an opening piece of the panel portion 21 when the opening portion of the can lid 1 is formed. Since the can lid 1 is of a full-open type, the score line 31 is formed in a circular shape or an approximately circular shape as shown in FIG. 7 , for example.
  • the sub score line 42 is provided on an inner side of the main score line 41 in the radial direction.
  • the sub score line 42 is formed in parallel to the main score line 41.
  • the sub score line 42 is, for example, a wedge-shaped groove provided on the outer surface of the panel portion 21.
  • the sub score line 42 is formed to have a depth smaller than that of the main score line 41. That is, a thickness of a portion of the panel portion 21 where the sub score line 42 is provided is formed thicker than a thickness of a portion of the panel portion 21 where the main score line 41 is provided. A part of the panel portion 21 is formed thin by the sub score line 42.
  • the outer protection portion 34a is formed by the upper layer 34c and a part of the intermediate layer 34e, and the upper layer 34c is located above the score line 31 and functions as a protection portion after the score line 31 is broken.
  • a part of the upper layer 34c and a part of the intermediate layer 34e of the panel portion 21 constituting the outer protection portion 34a are the convex portion 21b located on the inner surface of the panel outer peripheral portion 21a on the score line 31 side.
  • the convex portion 21b of the present embodiment is formed by a folded portion of the panel portion 21 in the second and third layers of the configuration of the outer protection portion 34a of the protection portion 34.
  • the tab 12 includes an attachment portion 51, a tip portion 52, and a finger hook portion 53.
  • the attachment portion 51, the tip portion 52, and the finger hook portion 53 are formed integrally.
  • the tip portion 52 presses a portion of the panel portion 21 that is adjacent to the inner side of the score line 31 in the radial direction to break the score line 31.
  • the ratio between the diameter of the score line 31 of the panel portion 21 and the inner diameter of the body portion 111 is set to 0.6 to 0.8, and more preferably, the ratio between the diameter of the score line 31 of the panel portion 21 and the inner diameter of the body portion 111 is set to 0.6 to 0.75.
  • the effervescing beverage which is the content filled in the can container 100 is exemplified, but the effervescing beverage is not limited to the above-described example. That is, the can container 100 exhibits the function of the foaming property of the effervescing beverage by being filled with the effervescing beverage, but it is needless to say that the can container 100 may be filled with a beverage other than the effervescing beverage.
