Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a diagram for explaining a beverage can 100 to which the present embodiment is applied. 1A is a plan view of the beverage can 100. FIG. Moreover, the figure (B) is sectional drawing at the time of seeing the drink can 100 from the front.
As shown in FIGS. 4A and 4B, the beverage can 100 according to the present embodiment has an opening at the top and a bottom (not shown) at the bottom and is formed in a cylindrical shape. A container main body (can body) 200 is provided which functions as a part of an accommodating portion in which the beverage is accommodated. In addition, the beverage can 100 is provided with a can lid 300 that is attached to the top of the container body 200 and closes the opening of the container body 200.

  In the present embodiment, a so-called two-piece can composed of two members, a container main body 200 and a can lid 300, is illustrated, but each configuration described below includes a cylindrical container main body, a can lid, The present invention can also be applied to a so-called three-piece can composed of three members of the bottom member. Moreover, each structure demonstrated below can be applied to things other than cans, such as a paper pack.

  A can lid 300 as an example of a lid member includes a panel 400 that is formed in a disk shape and functions as a substrate, as shown in FIG. Here, the outer peripheral edge of the panel 400 is fixed to the edge (upper edge) of the container body 200 by so-called winding. This fixing will be described in detail. In the present embodiment, first, the edge (upper edge) of the container body 200 as an example of the cylindrical member and the outer edge of the panel 400 are overlapped. Next, the mold is pressed against both the edge of the container body 200 and the outer edge of the panel 400 to perform bending processing.

  More specifically, as shown in the enlarged view of FIG. 5B, bending is performed so that the portion where the edge of the container body 200 and the outer edge of the panel 400 overlap is directed downward, The outer edge portion of the panel 400 is placed between the displacement part 210 of the container body 200 that is displaced downward by the bending process and the facing part 220 of the container body 200 that faces the displacement part 210. Next, the displacement part 210 is pressed so that the displacement part 210 approaches the opposite part 220. As a result, the outer edge of the panel 400 is fixed to the container body 200, and the can lid 300 is fixed to the container body 200. In other words, the outer edge of the panel 400 is sandwiched between the displacement part 210 and the facing part 220, and the can lid 300 is fixed to the container body 200.

  Moreover, in this embodiment, as shown to the same figure (A) and (B), the circular opening part 310 used as a drinking mouth when a user drinks an internal drink is formed in the center part of the panel 400. FIG. . In the present embodiment, the opening 310 is formed at the center of the can lid 300, but the opening 310 may be located at a position biased toward the outer periphery of the can lid 300. Moreover, in this embodiment, as shown to the same figure (A) and (B), the sealing member 500 as an example of the closing piece which blocks the opening part 310 formed in the can lid 300 is stuck on the surface of the can lid 300 ( Have been glued).

  Here, in the sealing member 500, as shown in FIG. 5A, a base 510 that is formed in a circular shape and closes the opening 310 formed in the can lid 300, and an outer edge portion of the base 510 is directed outward. A protruding first protruding portion 520 and a second protruding portion 530 that protrudes outward from the outer edge portion of the base portion 510 are formed. Here, the second protrusion 530 is provided on the side opposite to the side where the first protrusion 520 is provided.

  In this embodiment, as shown in the enlarged view of FIG. 5B, the end of the second protrusion 530 formed on the seal member 500 is formed by the displacement portion 210 and the facing portion 220 described above. The end portion of the second projecting portion 530 is sandwiched and mechanically fixed. For this reason, in this embodiment, the seal member 500 after being peeled off from the panel 400 is difficult to be detached from the can lid 300.

  The second protrusion 530 of the seal member 500 is fixed when the outer edge of the can lid 300 and the edge of the container main body 200 are overlapped with each other, between the outer edge and the edge. It can also be done by arranging. In addition, in the structure demonstrated above, although the 2nd protrusion part 530 does not enter into the inside of the drink can 100 (refer the enlarged view of FIG.1 (B)), a 2nd protrusion part is provided between an outer edge part and an edge part. In the configuration in which 530 is disposed, there is a possibility that the second protrusion 530 protrudes inside the beverage can 100 and the second protrusion 530 touches the beverage inside.

  Here, the structure of the seal member 500 is not particularly limited, but is preferably formed in a multilayer structure including a metal layer. The seal member 500 can employ, for example, a structure in which an aluminum foil and a plastic film are laminated or a structure in which a resin is applied to the aluminum foil. Moreover, the part pinched | interposed as mentioned above among the sealing members 500 can also be made thicker than another part. In this case, the sealing member 500 is not easily broken. Here, the metal layer, particularly the aluminum foil, is excellent in airtightness, moisture-proof property and light-shielding property, but it cannot be said that the tearability and impact resistance are sufficient. On the other hand, the seal member 500 is a weak point of the aluminum foil, and by adopting a material excellent in tearability and impact resistance, the metal layer and the film layer stand in a complementary relationship with each other, and as a composite material, It becomes a sealing material that excels in light shielding and sealing properties and is strong against external forces.

  Here, when the beverage inside the beverage can 100 is drunk by the user, the first protrusion 520 is lifted upward by the user. As a result, the sealing member 500 is gradually peeled off from the panel 400 so that the opening 310 is exposed as shown in FIG. 2A (a view showing the beverage can after the sealing member is peeled off from the panel). Become. In addition, after the sealing member 500 is peeled from the panel 400, the sealing member 500 is in a state of sagging as shown in FIG.

  The seal member 500 is bonded to the can lid 300 by, for example, thermal bonding. More specifically, first, before the sealing member 500 is bonded to the can lid 300, an adhesive (heat sealing agent) is applied to one surface of the sealing member 500 and dried. The seal member 500 thus coated with the adhesive is thermally bonded to the portion of the can lid 300 where the opening 310 is provided. In other words, a part of the adhesive is melted by applying heat to a part of the seal member 500, and the seal member 500 is attached to the can lid 300 by the melted adhesive. More specifically, the seal member 500 is affixed to a portion of the can lid 300 that is located around the opening 310. In this embodiment, the case where an adhesive is used has been described. However, the sealing member 500 may be formed of a resin such as nylon, and the resin may be melted to perform bonding.

  More specifically, in the present embodiment, heat is applied to the seal member 500 in a state where the seal member 500 is pressed against the can lid 300, and the adhesive melts by this heat, and the seal member 500 becomes the can lid. Glued to 300. When the adhesion of the seal member 500 is completed, the can lid 300 with the opening 310 closed by the seal member 500 is completed. Thereafter, in the present embodiment, the can lid 300 is fixed to the opening of the container body 200 filled with a beverage by the above-described tightening. When this tightening is performed, as described above, the second projecting portion 530 of the seal member 500 is sandwiched between the displacement portion 210 and the facing portion 220. Thereby, the drink can 100 (refer FIG. 1) filled with the drink is completed.

In the same manner as described above, the seal member 500 includes a base 510 that closes the opening 310, a first protrusion 520 that protrudes outward from the outer edge of the base 510, and also protrudes outward from the outer edge of the base 510. The second protruding portion 530 is provided. As shown in the enlarged view of FIG. 5B, the second protrusion 530 of the seal member 500 is formed with a through hole 531 that penetrates in the thickness direction of the seal member 500.

  Further, in the present embodiment, a protruding portion 490 protruding upward from the upper surface of the panel 400 is formed (see an enlarged view of FIG. 3B). Here, the projecting portion 490 is formed in a cylindrical shape and extends upward in the drawing, and is formed at a top portion of the base portion 491 and has a diameter larger than the diameter of the base portion 491, and on the upper surface of the panel 400. And an opposing portion 492 facing each other. Here, in the present embodiment, the base portion 491 of the protruding portion 490 is inserted into the through hole 531 formed in the seal member 500. In the present embodiment, the diameter of the facing portion 492 is larger than the diameter of the through hole 531. For this reason, also in this embodiment, the seal member 500 after being peeled off from the panel 400 is difficult to be detached from the can lid 300.

  Here, when the beverage inside the beverage can 100 is drunk, the first protrusion 520 of the seal member 500 is pulled upward by the user in the same manner as described above. As a result, as shown in FIG. 4, the seal member 500 is bent at the base of the seal member 500 and the opening 310 formed in the panel 400 is exposed.

FIG. 5 is a view showing the can lid 300 before the seal member 500 is fixed.
Before the seal member 500 is fixed to the can lid 300, as shown in the enlarged view of FIG. 5B, an opposing portion 492 (see FIG. 3) is formed on the top of the base portion 491 in the protruding portion 490. Absent. When fixing the seal member 500 to the can lid 300, first, the base 491 of the protrusion 490 is passed through the through-hole 531 formed in the seal member 500 as shown by the arrow in FIG. Next, by using a pressing mechanism (not shown), the top of the base 491 is pressed from above and the base 491 is crushed.

  Thereby, the top part side of the base part 491 becomes flat shape, and the opposing part 492 (refer FIG. 3) as an example of a flat part comes to be formed in the top part of the base part 491. Here, when the facing portion 492 is formed by the base portion 491 being crushed in this manner, the facing portion 492 is pressed against the seal member 500 and the panel 400. As a result, in the present embodiment, the second protruding portion 530 of the seal member 500 is sandwiched between the facing portion 492 and the panel 400, and the second protruding portion 530 is held by the facing portion 492 and the panel 400. By this holding, the sealing member 500 is fixed to the panel 400. In addition, also in the present embodiment, the seal member 500 is mechanically fixed.

  Thus, also in this embodiment, the seal member 500 is sandwiched and fixed. For this reason, it is preferable to make the thickness of the sandwiched portion of the seal member 500 larger than the thickness of other portions, as described above. Further, it is preferable that the seal member 500 is formed so as to include a metal layer as described above.

When a plurality of protrusions 490 are provided in this way, the load acting on the seal member 500 from the protrusions 490 is dispersed, and damage to the seal member 500 is suppressed. In this case, the separation of the seal member 500 is further less likely to occur.

  Although not described above, when the container body 200 and the can lid 300 are made of aluminum, for example, it is preferable to use aluminum for the metal layer of the seal member 500. In addition, it is preferable to use the same material as that used for the container body 200 and the can lid 300 for the metal layer of the seal member 500. In this case, the beverage can 100 can be discarded without separating the container body 200, the can lid 300, and the seal member 500. In other words, the beverage can 100 can be discarded without sorting for reuse.

  Moreover, although the above demonstrated the case where the sealing member 500 was peeled off from the can lid 300 by the 1st protrusion part 520 being gripped by the user, FIG. 7 (the figure which showed the other structural example of the drink can).
