  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<First Embodiment>
FIG. 1 is a schematic diagram for explaining an example of a beverage can to which the present invention is applied, and FIG. 2 is a schematic plan view for explaining a lid member in the beverage can to which the present invention is applied.

  The beverage can 1 shown here includes a cylindrical body 3 having a bottom 2 on one end side and a lid member 4 fixed to the other end side of the cylindrical body 3.

  The lid member 4 is formed in a disk shape with a metal plate, and is fixed to the other end of the cylindrical body 3 by so-called winding.

  Here, the lid member 4 is formed with a planned opening region 5 in which a planned breaking line 15 is formed in a drinking mouth shape at a position shifted from the center (an eccentric position). By breaking the planned break line 15, the planned opening area 5 is pushed downward and a drinking mouth (not shown) is opened.

  The planned breaking line 15 is provided with a cutting groove (not shown) that does not break with an impact force when the beverage can 1 is dropped or a force that pushes the planned opening area 5 with a fingertip.

  Due to the cutting groove (not shown), when the pressing by the opening tab 6 (for example, pressure more than pressing with a fingertip) is applied to the planned opening area 5, the planned breaking line 15 is broken and the planned opening area 5 is opened. Thus, a drinking mouth (not shown) is formed.

  Further, the opening tab 6 is connected and pivotally attached to the lid member 4 such that one edge 10 in the longitudinal direction covers the planned opening area 5.

  The opening tab 6 is formed into a rigid plate member by bending the periphery of the substantially elliptical aluminum plate member.

  Further, the connecting plate 8 is formed by punching the opening groove 7 in a U shape on the longitudinal center axis of the opening tab 6.

  The connecting plate 8 is connected and fixed to a substantially central position of the lid member 4, that is, a position in the vicinity of the planned opening area 5 through the rivet 9 so as to be on the same line as the planned opening area 5. Thereby, it is set as the state where one edge part 10 of the longitudinal direction of the tab 6 for opening covers the opening plan area | region 5. As shown in FIG.

  Further, the connecting plate 8 is connected and fixed to the lid member 4 by the rivet 9 by the opening groove portion 7, and the opening tab 6 can be moved up and down in the longitudinal direction with the connecting plate 8 as a fulcrum. .

  Further, a ring portion 13 is formed by punching an opening hole on the other edge portion 11 side in the longitudinal direction of the opening tab 6.

  One edge 10 of the unsealing tab 6 is moved downward with the connecting plate 8 connected and fixed by the rivet 9 as a fulcrum by pulling and raising the tip of the ring portion 13 with a finger.

  A recess 12 having an inner diameter into which one edge 10 of the opening tab 6 can be inserted is formed in the planned opening area 5 where the one edge 10 of the opening tab 6 is located.

  Next, FIG. 3 (A) is a schematic cross-sectional view for explaining a recess in a planned opening area in a beverage can to which the present invention is applied, and FIG. 3 (B) is an opening tab of the beverage can to which the present invention is applied. It is a cross-sectional schematic diagram for demonstrating an action operation.

  Here, the recessed part 12 is formed in the depth which the other edge part 11 side of the tab 6 for opening stands by the one edge part 10 of the tab 6 for opening being inserted. Furthermore, the recessed part 12 is formed with an inclined surface 14 that is inclined from the fixing position of the opening tab 6 toward the longitudinal axis of the opening tab 6 (see FIG. 3A).

  By forming the inclined surface 14 in this manner, one side of the opening tab 6 is pressed against the surface of the inclined surface 14 in the recess 12 by pushing one edge 10 of the opening tab 6 downward with a finger or the like. The lower side surface of the edge portion 10 is in uniform contact (see FIG. 3B).

  Accordingly, the other edge 11 side of the opening tab 6 stands up with the connecting plate 8 connected and fixed by the rivet 9 as a fulcrum, and a space is formed between the lid member 4 and the other edge 11 of the opening tab 6. Will occur. As a result, a fingertip (not shown) can be inserted between the lid member 4 and the other edge 11 of the opening tab 6 and can be easily hooked into the ring portion 13 of the opening tab 6. .

  In the present embodiment, only the portion of the planned opening area covered with the opening tab is formed in the recess, but it is not always necessary to form only the portion of the planned opening area in the recess.

  For example, if one edge of the opening tab is inserted into the planned opening area and the other edge of the opening tab rises, the entire opening planned area is formed in the recess. It does not matter.

  Moreover, in this Embodiment, although the tab for opening is formed from the plate-shaped member which has rigidity, it is not necessarily formed from the plate-shaped member which has rigidity.

  For example, any material or shape may be used as long as it can be opened by pressing the planned opening area. However, it is desirable to form from the plate-shaped member which has rigidity in the point that an opening plan area | region can be pressed by surface contact.

  In the present embodiment, the concave portion is inclined from the pivot attachment position of the opening tab toward the longitudinal axis of the opening tab, but is not necessarily on the longitudinal axis of the opening tab. There is no need to be inclined toward the front.

  However, the opening tab is evenly pressed against the inclined surface of the recess in the planned opening area so that the opening tab is pressed uniformly and the other edge of the opening tab is surely raised. It is desirable to make it inclined toward the longitudinal axis of the tab.

  In the present embodiment, the lid member is formed with a planned fracture line surrounding the planned opening area, but it is not always necessary to form the planned fracture line.

  However, it is desirable to form a planned fracture line surrounding the planned opening area in that it can be reliably opened by pressing the planned opening area.

  In this embodiment, a rivet is used to connect the opening tab and the lid member, but it is not always necessary to use a rivet.

  For example, any mechanism can be used as long as the opening tab and the lid member can be connected to each other by, for example, providing a protrusion on the lid member and fitting a hole provided in the connection plate of the opening tab into the protrusion to connect the opening member integrally. It doesn't matter.

  In the beverage can 1 of the present invention having the above configuration, one edge portion 10 of the opening tab 6 is pushed downward by the fingertip A as shown in FIG.

  Thus, one edge 10 of the opening tab 6 is inserted into the recess 12 in the planned opening area 5 with the connecting plate 8 connected and fixed by the rivet 9 as a fulcrum.

  In this way, by pressing down one edge 10 of the opening tab 6, the lower surface of the one edge 10 of the opening tab 6 is in close contact with the inclined surface 14 of the recess 12.

  Here, when one edge portion 10 of the opening tab 6 is pushed down, the other edge portion 11 of the opening tab 6 stands while moving upward with the connecting plate 8 connected and fixed by the rivet 9 as a fulcrum.

  This secures a space for the finger to enter between the other edge 11 of the opening tab 6 and the surface of the lid member 4, and the fingertip between the other edge 11 of the opening tab 6 and the surface of the lid member 4. A can be easily inserted.

  Therefore, as shown in FIG. 5, in the state where the ring portion 13 of the unsealing tab 6 is hooked by the fingertip A, it can be further rotated in the direction of the arrow B in the drawing.

  Thus, one edge 10 of the opening tab 6 strongly presses the inclined surface 14 in the recess 12 of the planned opening area 5 with the connecting plate 8 connected and fixed by the rivet 9 as a fulcrum.

  The planned fracture line 15 provided so as to surround the planned opening area 5 with the pressing force at this time is broken. As a result, the planned opening area 5 is opened and the beverage as the contents can be poured out.

  In the beverage can of the present invention, it is possible to instantaneously form a space where a finger can enter between the other edge of the opening tab and the lid member by pushing down one edge of the opening tab.

  Accordingly, for example, the opening tab can be easily pulled up by holding the ring portion with the fingertip without causing the opening tab by the artificial nail.

  In addition, it is possible to secure a sufficient space for a finger to enter between the other edge of the opening tab and the lid member even in a state where gloves are worn as in winter.

<Second Embodiment>

As will be described in detail with reference to FIG. 4, a planned opening area 5 is formed which can be opened by a predetermined pressing formed on the lid member 4.

  One of the tabs 6 for unsealing that is connected to the lid member 4 in the vicinity of the planned opening area 5 and that can be inserted into a recess 12 formed in one of the longitudinal edges 10 in the planned opening area 5. The edge 10 is inserted into the recess 12.

  Here, when one edge 10 of the opening tab 6 is pushed down into the recess 12, the other edge 11 of the opening tab 6 moves upward with the connecting plate 8 connected and fixed by the rivet 9 as a fulcrum. While standing up.

  This secures a space for the finger to enter between the other edge 11 of the opening tab 6 and the surface of the lid member 4, and the fingertip between the other edge 11 of the opening tab 6 and the surface of the lid member 4. Insert A.

  Further, as will be described in detail with reference to FIG. 5, the ring portion 13 of the opening tab 6 is rotated in the direction indicated by the arrow B in the figure while being hooked by the fingertip A.

  Thus, one edge 10 of the opening tab 6 strongly presses the inclined surface 14 in the recess 12 of the planned opening area 5 with the connecting plate 8 connected and fixed by the rivet 9 as a fulcrum.

  The planned fracture line 15 provided so as to surround the planned opening area 5 with the pressing force at this time is broken. As a result, the planned opening area 5 is opened and the beverage as the contents can be poured out.

  In the method for opening a beverage can according to the present invention, a space where a finger can enter is instantaneously inserted between the other edge of the opening tab and the lid member by pushing down one edge of the opening tab into the recess of the opening scheduled area.
