In particular, the configuration of the can lid 10 according to the present embodiment will be described with reference to FIGS. 1 to 7. The can lid 10 according to the present embodiment is composed of a lid body 100, a tab 200 fixed to the lid body 100, and a slide member 300 attached to the lid body 100. The lid 100, the tab 200, and the slide member 300 constituting the can lid 10 are all made of a metal such as aluminum.

The lid 100 includes an engraved score 110, a first rivet portion 120 for fixing the tab 200, and a pair of protrusions 130. As shown by the middle dotted line in FIGS. 1 and 2, the region bordered by the score 110 is the planned opening region O. Further, in FIG. 2, the area indicated by the XX line is the opening start area OS. This opening start region OS exists in the vicinity of the first rivet portion 120. Further, the pair of projecting portions 130 have a substantially conical shape and are formed in a region facing the tab 200, and play a role as a detent projection for restricting the movement of the tab 200 in the rotational direction. ing. Further, the lid 100 is also provided with a second rivet portion 140 that rotatably supports the slide member 300. In addition to the method of applying the rivet processing to the lid body 100, the second rivet portion 140 may be provided by adhering a member to be the second rivet portion 140.

The tab 200 has a through hole 210 for being fixed by the first rivet portion 120, a front end portion 220 on one side of the through hole 210, and a rear end portion 230 on the opposite side. Further, the tab 200 is also provided with a U-shaped hole 240 so that the tab 200 is easily deformed when the tab 200 is raised. Further, the tab 200 is also provided with a finger hook ring 250 on which a finger can be hooked. In the state where the tab 200 is fixed to the lid 100, the tip portion 220 of the tab 200 is located in the planned opening region O in the lid 100. Further, the rear end portion 230 of the tab 200 is located on the opposite side of the tip portion 220 with the portion where the tab 200 is fixed to the lid 100 (the portion where the first rivet portion 120 is provided). .. When opening the planned opening area O, the user usually puts his finger on the rear end 230 or the finger hook ring 250 to raise the tab 200.

In the above embodiment, a case is shown in which a protruding portion (projecting portion 130) that is in sliding contact with the slide member 300 is formed on the lid 100 in the process of sliding the slide member 300 from the initial position. However, in the present invention, a protruding portion that is in sliding contact with the slide member may be provided on the tab in the process of sliding the slide member from the initial position. For example, in the configuration shown in the above embodiment, the tab 200 may be provided with a protruding portion protruding toward the lid 100 side. That is, in the process of rotating (sliding) the slide member 300 from the initial position, the insertion portion 310 enters the gap between the lid 100 and the tab 200, and then the insertion portion 310 protrudes from the tab 200. The protruding portion may be provided so as to enter between the portion (not shown) and the lid 100. As a result, as in the case of the above embodiment, by sliding the slide member 300, the rear end portion 230 of the tab 200 is moved in a direction away from the surface of the lid 100 with the first rivet portion 120 as a fulcrum. Needless to say, you can do it.

Further, in the present invention, it is also possible to adopt a configuration in which the slide member is further provided with a protruding portion that is in sliding contact with the lid or the tab in the process of sliding the slide member from the initial position.

The protruding portion 310X may be provided on at least one of both sides of the insertion portion 310. If such a configuration is adopted, in the process of rotating (sliding) the slide member 300 from the initial position, the insertion portion 310 enters the gap between the lid 100 and the tab 200, and the protrusion 310X is the lid. It will be in sliding contact with 100 or tab 200. When the protrusions 310X are provided on both sides of the insertion portion 310, each protrusion 310X is in sliding contact with both the lid 100 and the tab 200. As a result, as in the case of the above embodiment, by sliding the slide member 300, the rear end portion 230 of the tab 200 is moved in a direction away from the surface of the lid 100 with the first rivet portion 120 as a fulcrum. Needless to say, you can do it.

In the case of the above-described embodiment, in the initial state, the insertion portion 310 of the slide member 300 does not enter the gap between the lid 100 and the tab 200. Therefore, in the process of sliding the slide member 300, the insertion portion 310 enters the gap between the lid 100 and the tab 200, so that the rear end portion 230 of the tab 200 is covered with the first rivet portion 120 as a fulcrum. It is possible to move the body 100 away from the surface to some extent. However, it is desirable to provide a protruding portion in order to maximize the gap formed between the rear end portion 230 of the tab 200 and the surface of the lid 100 . Na us, the protruding portion may be provided with respect to two or more of the cover body 100 and the tabs 200 and the slide member 300. Further, when the tab 200 is used as a gripping surface without forming the finger hook ring 230, the entire tab 200 may be a protruding portion, or a part thereof may be provided with a protruding portion protruding toward the lid 100 side. good. Further, as a method of attaching the slide member, in addition to the method of attaching the slide member by the second rivet 140 as described above, various methods such as adhesive fixing can be used.
