In particular, the configuration of the can lid 10 according to the present embodiment will be described with reference to FIGS. The can lid 10 according to the present embodiment includes a lid 100, a tab 200 fixed to the lid 100, and a slide member 300 attached to the lid 100. Note that the lid 100, the tab 200, and the slide member 300 constituting the can lid 10 are all made of 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 projecting portions 130. As shown by the dotted lines in FIGS. 1 and 2, the area bordered by the score 110 is the planned opening area O. In FIG. 2, the area indicated by the line XX is the opening start area OS. The opening start area OS exists in the vicinity of the first rivet portion 120. The pair of protrusions 130 have a substantially conical shape, are formed in a region facing the tab 200, and play a role as detent protrusions that restrict movement of the tab 200 in the rotational direction. ing. Further, the lid body 100 is also provided with a second rivet portion 140 that pivotally supports the slide member 300 in a rotatable manner. The second rivet portion 140 can be provided by adhering a member to be the second rivet portion 140 in addition to the method of riveting the lid 100.

The tab 200 has a through-hole 210 to be fixed by the first rivet portion 120, a front end portion 220 on one side across the through-hole 210, and a rear end portion 230 on the opposite side. 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 ring 250 that can hook a finger. In a state where the tab 200 is fixed to the lid body 100, the distal end portion 220 of the tab 200 is located in the planned opening area O in the lid body 100. Further, the rear end portion 230 of the tab 200 is positioned on the opposite side of the front end portion 220 with a portion where the tab 200 is fixed to the lid body 100 (a portion where the first rivet portion 120 is provided) sandwiched therebetween. . When opening the planned opening area O, the user usually puts his / her finger on the rear end portion 230 or the finger hook ring 250 to cause the tab 200.

The slide member 300 has a through hole for being pivotally supported by an insertion portion 310 that moves the rear end portion 230 of the tab 200 away from the surface of the lid body 100 and a second rivet portion 140 provided in the lid body 100. 320 is provided. The insertion portion 310 has a tab-side edge thickness that can be inserted between the lid body 100 and the tab 200, and the slide member 300 attached to the lid body 100 has a second rivet portion. It can be rotated around 140. Accordingly, when the slide member 300 is rotated in the clockwise direction in FIG. 1, the slide member 300 is inserted in a state where a part of the slide member 300 (insertion portion 310) enters the gap between the lid body 100 and the tab 200. The member 300 can be slid (rotated).

<Slide of slide member>
In particular, with reference to FIGS. 8 and 9, the operation of the tab by sliding the slide member 300 will be described. FIG. 8 is a plan view of the can lid showing a state in which the slide member 300 is rotated by a predetermined angle in the clockwise direction from the initial position shown in FIG. FIG. 9 is a cross-sectional view taken along line A4-A4 in FIG. In the present embodiment, in a state where the slide member 300 is located at the initial position, the insertion portion 310 does not enter the gap between the lid 100 and the tab 200 (see FIG. 1). And it is comprised so that the insertion part 310 may enter in the clearance gap between the cover body 100 and the tab 200 by rotating the slide member 300 (sliding).

In the process of rotating (sliding) the slide member 300, after the insertion portion 310 enters the gap between the lid 100 and the tab 200, the insertion portion 310 contacts the protrusion 130, and then the protrusion 130. It will be in the state where it got on. In addition, in this embodiment, it is comprised so that the insertion part 310 may ride on the protrusion part 130 of the left side in the figure among a pair of protrusion parts 130 shown in FIG. As described above, the insertion portion 310 rides on the projecting portion 130 and comes into sliding contact with the first rivet portion 120 as a fulcrum, so that the rear end portion 230 moves away from the surface of the lid body 100. Thereby, a clearance gap is formed between the rear-end part 230 and the cover body 100 (refer FIG. 9).

<Excellent point of can lid according to this embodiment>
As described above, according to the can lid 10 according to the present embodiment, the rear end portion 230 of the tab 200 is moved away from the surface of the lid body 100 by sliding the slide member 300 from the initial position. Can do. Therefore, the tab 200 can be easily caused by inserting a finger into the gap formed between the rear end portion 230 and the lid body 100. Further, in the present embodiment, the slide member 300 rides on the protruding portion 130 as a detent projection that restricts the movement of the tab 200 in the rotational direction, whereby the rear end portion of the tab 200 is further away from the lid surface. It is possible to move to.

<Others>
In the above-described embodiment, the case where the projecting portion (projecting portion 130) that is in sliding contact with the slide member 300 is formed on the lid body 100 in the process of sliding the slide member 300 from the initial position is shown. However, in the present invention, in the process in which the slide member is slid from the initial position, the tab may be provided with a protruding portion that comes into sliding contact with the slide member. For example, in the configuration shown in the above embodiment, the tab 200 may be provided with a protruding portion that protrudes toward the lid 100 side. That is, in the process in which the slide member 300 is rotated (slid) from the initial position, the insertion portion 310 is inserted into the gap between the lid body 100 and the tab 200, and then the insertion portion 310 is provided on the tab 200. The protrusion may be provided so as to enter between the portion (not shown) and the lid 100. Accordingly, as in the case of the above-described 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 body 100 with the first rivet portion 120 as a fulcrum. Needless to say, you can.

In the present invention, it is also possible to adopt a configuration in which the slide member is provided with a protrusion that is in sliding contact with the lid or the tab in the process of sliding the slide member from the initial position. For example, in the above embodiment, the protrusion 310X can be provided in the insertion portion 310 of the slide member 300 as shown in FIG. In addition, what is necessary is just to provide this protrusion part 310X in at least any one of both surfaces of the insertion part 310. FIG. If such a configuration is adopted, in the process in which the slide member 300 is rotated (slid) from the initial position, the insertion portion 310 enters the gap between the lid body 100 and the tab 200, and the protrusion 310X is the lid body. 100 or the tab 200. When the protrusions 310 X are provided on both surfaces of the insertion part 310, each protrusion 310 X comes into sliding contact with both the lid 100 and the tab 200. Accordingly, as in the case of the above-described 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 body 100 with the first rivet portion 120 as a fulcrum. Needless to say, you can.

In the above-described embodiment, the insertion portion 310 of the slide member 300 does not enter the gap between the lid 100 and the tab 200 in the initial state. Therefore, in the process of sliding the slide member 300, the insertion portion 310 enters the gap between the lid body 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 to some extent in the direction away from the surface of the body 100. However, in order to maximize the gap formed between the rear end portion 230 of the tab 200 and the surface of the lid body 100, it is desirable to provide a protruding portion. And this protrusion part should just be provided in either the cover body 100, the tab 200, and the slide member 300 as above-mentioned. In addition, although the protrusion part should just be provided in any one of the cover body 100, the tab 200, and the slide member 300, you may provide it with respect to two or more. Further, when the tab 200 is formed as a gripping surface without forming the finger ring 250, the entire portion may be a protrusion, or a part thereof may be provided with a protrusion that protrudes toward the lid 100 side. Good. Furthermore, as a method for attaching the slide member, various methods such as adhesive fixing can be used in addition to the method using the second rivet 140 as described above.

<Modification of slide member>

By adopting such a configuration, it is possible to facilitate the insertion of the insertion portion 310 into the gap between the lid 100 and the tab 200 in the process of sliding the slide member, and the rear end portion of the tab 200. 230 can be gradually moved away from the surface of the lid 100.

In the present modification, the taper as described above is realized by bending the outer edge (tip end side) of the insertion portion 310. However, by changing the thickness of the metal plate such as aluminum constituting the insertion portion 310, the taper can be tapered as described above. Moreover, in this modification, the structure in case the distance from the cover body side end surface to the tab side end surface in the insertion part 310 changes gradually by providing an inclined surface on the upper side in FIG. However, by providing a stepped step, the distance from the lid-side end surface to the tab-side end surface of the insertion portion can be changed stepwise.

If the slide member according to this modification is employed, a large gap can be formed between the rear end portion 230 and the lid body 100 by sliding the slide member. Therefore, it is not necessary to provide the above-described protrusions (such as the protrusion 130). However, it goes without saying that the slide member and the protruding portion according to this modification may be used in combination.
