As a result, in the configuration according to the present embodiment, workability when the user grips the grip portion 520 is improved. Note that the protrusion 410 is not necessarily required and can be omitted. Further, even if the protruding portion 410 and the like are not provided on the can lid 300, the grip portion 520 can be lifted from the panel 400 by bending the seal member 500 at the base of the grip portion 520.

  FIG. 3 is a top view of the can lid 300 when the seal member 500 is attached to the can lid 300. In the present embodiment, the seal member 500 is bonded to the can lid 300 with an adhesive. More specifically, as shown in the figure, first, an adhesive is applied in a ring shape to an annular portion located around the opening 310 in the first surface 431 of the panel 400. .

  Thereafter, the sealing member 500 described above is pressed against the panel 400. As a result, the adhesive is positioned between the seal member 500 and the panel 400, and the seal member 500 is fixed to the panel 400 by the adhesive. In the present embodiment, the case where the adhesive is applied to the panel 400 side has been described. However, the adhesive may be applied to the seal member 500 side. In addition, a heat sealant that melts by heat can be used as the adhesive.

4 is a cross-sectional view taken along line IV-IV in FIG.
Although not described above, in the present embodiment, bending (curling) is performed on a portion of the panel 400 located around the opening 310, and the curled portion 90 is formed on the portion located around the portion. Is formed.

  More specifically, in this embodiment, bending is performed so that the edge 350 of the opening 310 approaches the outer peripheral edge 420 (see FIG. 2A) of the can lid 300. Further, in the present embodiment, as shown in FIG. 4, the edge 350 is opposed to the first surface 431 of the first surface 431 and the second surface 432 of the can lid 300 by this bending process. ing. Further, in the present embodiment, a gap 440 is formed between the first surface 431 and the edge portion 350. More specifically, in this embodiment, the cross-sectional shape of the annular portion surrounding the opening 310 of the panel 400 is substantially C-shaped.

  More specifically, in the present embodiment, as shown in FIG. 4, the curled portion 90 includes a curved portion 460 and a connection piece 480. Here, the bending portion 460 is formed in a substantially U shape (saddle shape) so that the adhesive can be accumulated. Further, the bending portion 460 has one end 461 on the center side of the panel 400 and has the other end 462 on the opposite side to the one end 461 side. Here, the other end 462 is connected to a panel body 470 formed in a flat plate shape.

  The connection piece 480 is connected to the one end 461 of the bending portion 460 and is provided so as to go from the one end 461 to the other end 462 of the bending portion 460. Further, the connection piece 480 is formed in a curved state so as to protrude upward in the drawing. In the present embodiment, the tip end (edge 350) of the connection piece 480 and the other end 462 of the bending portion 460 are not in contact with each other, and the tip end of the connection piece 480 and the other end 462 of the bending portion 460 are not contacted. Are separated from each other. More specifically, the distal end portion of the connection piece 480 and the first surface 431 of the panel 400 are not in contact with each other, and the distal end portion of the connection piece 480 and the first surface 431 of the panel 400 are separated from each other. ing.

  Here, when the seal member 500 is affixed to the can lid 300, an adhesive is applied around the opening 310 as described above. In other words, an adhesive is applied to the first surface 431 side of the panel 400. In the present embodiment, the applied adhesive is placed on the panel main body 470 as shown in FIG. Further, the adhesive enters a gap 440 formed between the distal end portion of the connection piece 480 and the other end portion 462 of the bending portion 460. In other words, it enters the gap 440 formed between the edge 350 and the first surface 431 of the can lid 300. Thereafter, the adhesive enters the curled portion 90. If it adds, it will enter in the area | region enclosed by the curved part 460 and the connection piece 480. FIG.

  In the present embodiment, the adhesive is accumulated in the curled portion 90, and the adhesive is cured in the curled portion 90. In the present embodiment, as shown in FIG. 4, a part of the adhesive is positioned on the outer surface of the connection piece 480 (the side opposite to the surface facing the space where the adhesive is accumulated among the plurality of surfaces of the connection piece 480. On the surface). In other words, the adhesive is also attached to a portion of the second surface 432 of the panel 400 that is opposed to the seal member 500 (see FIG. 1B) by the curl processing. In the present embodiment, the edge 350 (the tip of the connection piece 480) is covered with an adhesive. Here, in the present embodiment, the opening 310 is formed by punching, and if the cut surface of the edge 350 is left exposed, corrosion tends to occur on the cut surface of the edge 350.

FIG. 5 is a view showing a state after the sealing member 500 is bonded to the can lid 300.
When the internal pressure of the beverage can 100 increases or the beverage can 100 is turned upside down, a force for peeling the seal member 500 from the can lid 300 is applied to the seal member 500 (see arrow 5A in the figure). . By the way, in this embodiment, the site | part hardened | cured in the said curl part 90 among adhesives comes to be hooked on the connection piece 480 (edge part 350) in this case. For this reason, in this embodiment, the seal member 500 is difficult to peel off from the can lid 300.

Further, when the internal pressure of the beverage can 100 increases, the pressure acts on the boundary (interface) between the adhesive and the seal member 500, and there is a possibility that peeling occurs between the seal member 500 and the adhesive. Similarly, peeling may occur between the adhesive and the panel 400.
Here, although the description is omitted above, in this embodiment, the adhesion strength between the adhesive and the seal member 500 is larger than the adhesion strength between the adhesive and the panel 400. For this reason, in this embodiment, even if the internal pressure of the beverage can 100 increases, peeling between the adhesive and the seal member 500 is less likely to occur.

  On the other hand, peeling between the adhesive and the panel 400 is likely to occur. However, in this embodiment, as shown by an arrow 5B in FIG. 5, the outer surface of the connection piece 480 (the sealing member of the second surface 432). Adhesive is also attached to 500 facing portions), and this adhesive is pressed against the connection piece 480 by the internal pressure of the beverage can 100. In the present embodiment, as described above, the adhesive in the curled portion 90 is caught on the connection piece 480. For this reason, in this embodiment, peeling at the boundary between the adhesive and the panel 400 is less likely to occur.

  Here, in this embodiment, as described above, the adhesive strength between the adhesive and the seal member 500 is greater than the adhesive strength between the adhesive and the panel 400. In addition, there is a difference in adhesion strength. Although the description is omitted above, such a difference in adhesion strength can be easily realized by a base treatment called an anchor coat. The anchor coat is a base treatment for coating a specific compound in order to enhance the adhesive strength of the adhesive. Examples of the anchor coat agent include titanate compounds and urethane compounds. In the present embodiment, the side that strengthens the adhesive force is the seal member 500 side. Therefore, when the seal member 500 that has been subjected to the anchor coat process and the panel 400 that has not been subjected to the anchor coat process are bonded with an adhesive, the adhesive strength of the adhesive of the seal member 500 is greater than the adhesive strength of the adhesive of the panel 400. Become. The difference in adhesion strength can also be caused by making the surface property (for example, surface roughness) of the seal member 500 different from the surface property (for example, surface roughness) of the panel 400.

FIG. 6 is a view showing the sealing member 500 and the panel 400 when the sealing member 500 is peeled off from the panel 400.
When the seal member 500 is peeled off from the panel 400, the grip portion 520 described above is first gripped by the user. Note that, as described above, the grip portion 520 is in a state of being lifted from the panel 400 by the protruding portion 410 (see FIG. 1) formed on the panel 400, so that the grip portion 520 can be easily gripped. ing. Thereafter, in the present embodiment, the grip portion 520 is pulled by the user in a direction away from the panel 400, and the grip portion 520 is pulled in a direction opposite to the side where the grip portion 520 was originally located. .

  Thereby, as shown in FIG. 6, first, the seal member 500 is peeled from the panel 400 on the side where the grip portion 520 is provided. In the present embodiment, as described above, the adhesion strength between the adhesive and the seal member 500 is larger than the adhesion strength between the adhesive and the panel 400. For this reason, in this embodiment, as shown in FIG. 6, the seal member 500 is peeled from the panel 400 in a state where the adhesive is attached to the seal member 500. For this reason, in the beverage can 100 in this embodiment, the amount of the adhesive remaining on the panel 400 is reduced.

  Here, when the adhesive tends to remain on the panel 400, it is necessary to remove the adhesive remaining on the panel 400 from the can lid 300 when the beverage can 100 is discarded as a recycled product. In the configuration of the present embodiment, the adhesive is unlikely to remain on the panel 400 side, so that the beverage can 100 can be discarded without removing the adhesive remaining on the panel 400 from the can lid 300. .

The description of the operation when the seal member 500 is peeled off will be further continued.
As described above, after the seal member 500 is peeled from the panel 400 on the side where the grip portion 520 is provided, the grip portion 520 is further pulled by the user. Thereby, peeling between the panel 400 and the sealing member 500 further proceeds, and an opening 310 (see FIG. 2A) formed in the panel 400 appears. As a result, the user can drink the internal beverage.

  By the way, in this embodiment, as above-mentioned, the adhesion strength of the sealing member 500 and an adhesive agent is raised. Further, the adhesive that is located in the curled portion 90 and hardened is caught by the connection piece 480 (the edge portion 350). For this reason, as mentioned above, even if the internal pressure of the beverage can 100 increases, the seal member 500 is difficult to peel off. By the way, in this case, there is a possibility that the user is difficult to peel off the seal member 500. However, in this embodiment, since the adhesive strength between the adhesive and the panel 400 is weakened, the operating force when the seal member 500 is peeled off. Will be small.

In addition, when the seal member 500 is peeled off by the user, the cured adhesive is not caught on the connection piece 480 at the same time in the entire region of the curled portion 90 formed in an annular shape. As indicated by the arrows in the figure showing the sealing member 500 and the panel 400 when the member 500 is peeled off, the catches are sequentially generated. For this reason, increase of the operation force resulting from this catch is also suppressed. As a result, in this embodiment, even if an increase in the internal pressure of the beverage can 100 occurs, the seal member 500 is not easily peeled off. On the other hand, when the user peels off the seal member 500, the seal member 500 is easily peeled off.
More specifically, since the seal member 500 is peeled off when the internal pressure of the beverage can 100 is increased, the adhesive member 480 receives the adhesive in the entire curled portion 90, so the seal member 500 is peeled off. It becomes difficult. This is because when the seal member 500 is peeled off, the adhesive is peeled off from the panel 400 having a weak adhesive strength, and the connection piece 480 is also caught from one end. On the contrary, when the sealing member 500 is peeled off by the internal pressure of the beverage can 100, the adhesive is peeled off from the sealing member 500 having a strong adhesive strength, and the hooking of the connecting piece 480 is also performed in the entire area of the curled portion 90. Because it receives a load, it is difficult to peel off. In other words, the sealing member 500 is easy to peel off and difficult to peel off.

8-10 is a figure in order to demonstrate the process at the time of apply | coating an adhesive agent to the can lid | cover 300. FIG.
Application of the adhesive on the can lid 300 can be performed, for example, using a nozzle 910 that discharges the adhesive, as shown in FIG. More specifically, the adhesive can be applied to the can lid 300 by using the nozzle 910 that is disposed on the top of the can lid 300 and discharges the adhesive downward. More specifically, in the configuration shown in FIG. 8, the adhesive is discharged from the nozzle 910 and the can lid 300 is rotated in the circumferential direction.

  As a result, the adhesive is supplied to the curled portion 90 of the panel 400 and the portion located around the curled portion 90. In this case, for example, in order to apply the adhesive into the curled portion 90 of the can lid 300, the nozzle hole facing the curled portion 90 is appropriately enlarged to increase the amount of adhesive dripping on the curled portion 90. To do. Further, in the present embodiment, the width of the adhesive when the adhesive is discharged from the nozzle 910 (the width of the nozzle 910) is large, and only by rotating the can lid 300 once (by rotating the can lid 300 a plurality of times). In addition, an adhesive layer having a certain width can be formed as shown in FIG.

  In addition, although the example which rotates the can lid | cover 300 was demonstrated above, the nozzle 910 side can also be moved. In other words, the nozzle 910 can be moved along the circumferential direction of the can lid 300. At this time, the nozzle 910 can be rotated once in one direction, or returned to the initial state after being moved half a turn in one direction, and then moved half a turn in a direction opposite to this one direction. it can. Here, in this embodiment, a supply tube for supplying an adhesive to the nozzle 910 is provided on the upper portion of the nozzle 910 (not shown). As described above, the nozzle 910 is half-circulated in one direction. In the case where it is moved by half a circumference in the opposite direction after being moved, problems such as entanglement of the supply tube are less likely to occur.

Further, the adhesive can be applied to the can lid 300 by pressing the holding member 950 that holds the adhesive against the can lid 300.
More specifically, after the lower surface of the holding member 950 shown in FIG. 9 is once brought into contact with the adhesive located below, the holding member 950 is raised. Next, the lower surface of the holding member 950 is brought into contact with the surface of the can lid 300. As a result, the adhesive is applied to the surface of the can lid 300.

  More specifically, the holding member 950 is made of a flexible material such as foam rubber. Further, as shown in FIG. 9, the lower surface of the holding member 950 includes a first protrusion 951 and a second protrusion formed around the first protrusion 951 and surrounding the first protrusion 951. A portion 952 is formed. Here, the first protrusion 951 is formed in a circular shape when viewed from below in the figure. In the present embodiment, the diameter of the first protrusion 951 is smaller than the diameter of the opening 310 (see FIG. 2A) of the panel 400. The second protrusion 952 has an annular shape when viewed from below in the figure, and is formed around the first protrusion 951 and surrounding the first protrusion 951 as described above. ing. The second protruding portion 952 has a shape in which two inclined side surfaces intersect at the lowermost end (the cross section has a shape like an inverted triangle).

  Here, when the adhesive is applied to the can lid 300, as described above and as shown in FIG. 10A, the holding member 950 is lowered and the lower surface side of the holding member 950 is downward. Soak in the adhesive located in the. Thereafter, as shown in FIG. 4B, the holding member 950 is pulled upward. Here, in this embodiment, when the holding member 950 is pulled upward, the adhesive adheres to the place where the adhesive has been immersed. Further, the adhesive that has adhered to the side surface and the base of the second protrusion 952 moves downward, and the adhesive gathers at the top of the second protrusion 952.

  Thereafter, as shown in FIG. 3C, the lower surface of the holding member 950 is pressed against the upper surface (first surface 431) of the can lid 300. At this time, the first protrusion 951 enters the opening 310. At this time, since the diameter of the first protrusion 951 is smaller than the outer surface of the connection piece 480 (see also FIG. 4), the adhesive adhering to the side surface of the first protrusion 951 is separated from the outer surface of the connection piece 480. Contact. As a result, the adhesive is applied to the outer surface of the connection piece 480.

  Further, in the present embodiment, as shown in FIG. 10C, the second projecting portion 952 faces the gap 440 (see also FIG. 4) formed in the can lid 300. As a result, the adhesive that has gathered at the top of the second protrusion 952 enters the curl portion 90 through the gap 440. Further, a portion (flat portion) located around the second projecting portion 952 on the lower surface of the holding member 950 also contacts the panel 400. Thereby, an adhesive agent comes to adhere also to the cyclic | annular site | part located in the circumference | surroundings of the gap | interval 440 of the can lid 300. FIG. Thereafter, the holding member 950 is separated from the can lid 300, and the adhesive of the can lid 300 is attached as shown in FIG.

  In the present embodiment, as shown in FIG. 4 and the like, the case where the adhesive enters deeper than the gap 440 (the case where the adhesive is filled in the curled portion 90) has been described. As shown in (a diagram showing another embodiment of the can lid 300), a configuration in which the adhesive does not enter the back side of the gap 440 can also be adopted. In the configuration shown in FIG. 11, the connection piece 480 is longer than the configuration shown in FIG. 4 and the like, and the tip of the connection piece 480 reaches the vicinity of the other end 462 (first surface 431). As a result, the gap 440 formed between the connection piece 480 and the other end 462 is reduced, so that the adhesive does not enter the back side of the gap 440.

  Here, also in the configuration shown in FIG. 11, the contact area between the adhesive and the panel 400 increases. Further, the cured adhesive is sandwiched between the connection piece 480 and the other end 462 (first surface 431), and a portion of the adhesive located between the connection piece 480 and the other end 462. Movement is regulated. As described above, even when the adhesive does not enter further to the back than the gap 440 (a configuration in which the adhesive is not filled in the curled portion 90), the seal member 500 is difficult to peel off from the can lid 300.
