Description

The present invention relates to beverage cans and can lids.

The can lid that comes with a beverage can has an opening piece that is located where the beverage spout is formed, and a tab for opening the spout. In the commonly used stay-on-tab type can lid, when the tab is pulled up, the opening piece is pressed by the end of the tab and pushed into the inside of the beverage can. This opens the spout (see, for example, Patent Document 1).

JP 2019-206016 A

The drinking spout of a beverage can is located in one of the two halves of the surface of the can lid, and is only large enough for the beverage to flow out. When a user holds the beverage can and drinks from the drinking spout, the area of the surface of the can lid where the drinking spout is not formed is usually placed in front of the user's nose. Therefore, it is difficult for the aroma of the beverage inside the beverage can to reach the user while he or she is drinking. If the odor inherent to the material of the can lid reaches the user, it can affect the taste judgment of the beverage.

The beverage can for solving the above problem is a beverage can having a can lid with a disk-shaped panel portion and a tab attached to the panel portion, the panel portion has a plurality of opening pieces that are pushed into the beverage can by lifting the tab, the plurality of opening pieces include a drinking spout piece and a scent spout piece located on the opposite side of the drinking spout piece with respect to the center of the panel portion, the tab has a pressing portion that presses the opening piece when the tab is lifted, and a finger hook portion that is located on the opposite side of the pressing portion with respect to the center of the panel portion and on which a user's finger is hooked, the finger hook portion has a tab hole that is a hole that penetrates the tab in the thickness direction, and the tab is attached to the panel portion so as to be rotatable between a position where the pressing portion is located on the scent spout piece and a position where the pressing portion is located on the drinking spout piece.

The can lid for solving the above problem is a can lid that is attached to a beverage can and includes a disk-shaped panel portion and a tab attached to the panel portion, the panel portion has a plurality of opening pieces that are pushed into the beverage can by lifting the tab, the plurality of opening pieces include a drinking spout piece and a scent spout piece located on the opposite side of the drinking spout piece with respect to the center of the panel portion, the tab includes a pressing portion that presses the opening piece when the tab is lifted, and a finger hook portion that is located on the opposite side of the pressing portion with respect to the center of the panel portion and on which a user's finger is hooked, the finger hook portion having a tab hole that is a hole that penetrates the tab in the thickness direction, and the tab is attached to the panel portion so as to be rotatable between a position where the pressing portion is located on the scent spout piece and a position where the pressing portion is located on the drinking spout piece.

According to the above configuration, the drinking spout is formed by pushing in the drinking spout piece, and the aroma spout is formed by pushing in the aroma spout piece. Then, when a user of the beverage can drinks a beverage from the drinking spout, the aroma spout is placed in front of the user's nose. Therefore, when the user is drinking a beverage, the aroma of the beverage inside the beverage can easily reaches the user through the aroma spout, thereby enhancing the taste of the beverage.

In addition, two sounds are made when the aroma vent is opened and when the drinking spout is opened. This allows the user to perceive the difference from conventional cases where only the drinking spout is opened not only visually and olfactoryly, but also aurally. This allows the user to clearly perceive the difference from conventional cases, leaving a strong impression on the user of the uniqueness of the beverage can.

In the above configuration, before the beverage can is opened, the pressing portion may be disposed on the aroma spout.
According to the above configuration, it is possible to guide the user in the method of opening the beverage can so that the aroma port is opened before the drinking spout. By opening the aroma port first, the user can enjoy the aroma of the beverage before drinking it, and can also enjoy the aroma from the aroma port while opening the drinking spout.

In the above configuration, the can lid may have a structure for fixing the tab in a position where the pressing portion is disposed on the aroma spout before the beverage can is opened.
According to the above configuration, it is possible to more accurately guide the opening method in which the aroma port is opened before the drinking port.

In the above configuration, after the beverage can is opened, the tab hole of the tab may be positioned above the aroma port formed by pushing the aroma port piece into the beverage can.

According to the above configuration, when a user drinks a beverage from the drinking spout, the finger hook of the tab is positioned between the user's nose and the vicinity of the aroma port on the panel part. Therefore, while the aroma from the aroma port reaches the user through the tab hole, the user's nose is prevented from entering the aroma port, and therefore inadvertent contact between the nose and the aroma port is prevented.

In the above configuration, when the panel portion and the tab are overlapped and viewed so that the tab hole is positioned above the aroma hole, the aroma hole may be larger than the tab hole and may not extend beyond the outer edge of the tab.

With the above configuration, the entire inside of the tab hole overlaps with the aroma vent, making it easier for the aroma of the beverage inside the beverage can to reach the user through the aroma vent, and because the aroma vent does not extend beyond the outer edge of the tab, inadvertent contact between the nose and the aroma vent is effectively prevented.

In the above configuration, the drinking piece and the aroma piece may be different in size.
According to the above-mentioned configuration, the pitch of the sound produced when the aroma opening is opened is different from the pitch of the sound produced when the drinking opening is opened, which enhances the user's enjoyment when opening the beverage can.

In the above configuration, the aroma spout piece may be smaller than the drinking spout piece.
According to the above configuration, when the aroma vent is opened before the drinking vent, the sound accompanying the opening gets louder in the order of opening, which increases the user's anticipation of drinking from the beverage can and further enhances the user's interest.

In the aforementioned configuration, a width of the finger hook portion may increase toward an end portion of the finger hook portion opposite the pressing portion.
According to the above-mentioned configuration, by hooking a finger on the edge of the finger hook portion, it is easy to apply force to the tab for rotating it, thereby reducing the burden on the user when rotating the tab.

In the aforementioned configuration, an end portion of the finger hook portion opposite the pressing portion may be warped in a direction away from the panel portion.
According to the above-mentioned configuration, since it is easy to put a finger on the side of the finger grip portion, it is easy to apply a force to rotate the tab, and therefore it is possible to reduce the burden on the user when rotating the tab.

In the above configuration, the panel portion may have at least one of a marking indicating the distinction between the aroma port formed by pushing the aroma port piece into the beverage can and the drinking spout formed by pushing the drinking spout piece into the beverage can, and a marking indicating the order in which the drinking spout and the aroma port are to be opened.

The above configuration makes it easier for users to understand how to drink from a beverage can and how to open a beverage can.

The present invention can improve the flavor of beverages.

An embodiment of a beverage can and a can lid will be described with reference to the drawings. Note that the up-down direction in the following description refers to the up-down direction when the beverage can is placed upright and stationary on a horizontal surface.
[Overall structure of beverage can]
1, a beverage can 10 includes a can body 20 and a can lid 30. The can body 20 includes a cylindrical tube portion 21 and a bottom portion 22 that closes the lower end of the tube portion 21. The can lid 30 is a stay-on-tab type can lid, and includes a lid plate portion 40 that closes the upper end of the tube portion 21, and a tab 60 attached to the lid plate portion 40.

The can body 20 and the cover plate 40 are mainly formed from metal plates such as aluminum or steel. The tab 60 is also formed from the same metal as the cover plate 40. The beverage can 10 may be a three-piece can or a two-piece can. In a three-piece can, the cylindrical portion 21 and the bottom portion 22 are formed separately and then joined together to form the can body 20. In a two-piece can, the cylindrical portion 21 and the bottom portion 22 are formed integrally. After the beverage is filled into the can body 20, the can lid 30 is attached to the can body 20 to form the beverage can 10.

The type of beverage filled in the beverage can 10 is not particularly limited. Beverages whose aroma has a strong effect on the taste are suitable for filling the beverage can 10 of this embodiment. Examples of such beverages include beer, coffee, and tea.

[Can lid configuration]
The detailed structure of the can lid 30 will be described with reference to FIGS.
2 shows a planar structure of the cover plate 40. The cover plate 40 includes a panel portion 41 having a disk shape and an annular portion 42 located on the outer periphery of the panel portion 41. A structure for attaching the can lid 30 to the can body 20 is formed in the annular portion 42 by curling or the like.

The panel portion 41 has a drinking mouth piece 53 defined by a first score portion 51 and a scented mouth piece 54 defined by a second score portion 52. Each of the drinking mouth piece 53 and the scented mouth piece 54 is an example of an opening piece. Each of the first score portion 51 and the second score portion 52 is a curved portion where a groove formed on the upper surface of the panel portion 41 extends.

The panel portion 41 has, at its center, a rivet 57 which is a protrusion for attaching the tab 60 to the panel portion 41. The aroma spout piece 54 is located on the opposite side of the center of the panel portion 41 from the drinking spout piece 53. In other words, the drinking spout piece 53, the rivet 57, and the aroma spout piece 54 are aligned on a single imaginary straight line A1 which passes through the center of the panel portion 41. The drinking spout piece 53 is located in one area obtained by bisecting the panel portion 41 with a straight line perpendicular to the straight line A1, and the aroma spout piece 54 is located in the other area.

The aroma spout piece 54 is smaller than the drinking spout piece 53. The shapes of the drinking spout piece 53 and the aroma spout piece 54 are not particularly limited, and the drinking spout piece 53 and the aroma spout piece 54 have, for example, an approximately elliptical or approximately circular shape.

The drinking spout piece 53 is separated from the rest of the panel portion 41 at the first score portion 51, and the drinking spout piece 53 is pushed into the beverage can 10, opening the drinking spout 70. The aroma spout piece 54 is separated from the rest of the panel portion 41 at the second score portion 52, and the aroma spout piece 54 is pushed into the beverage can 10, opening the aroma spout 71. In each of the first score portion 51 and the second score portion 52, the groove may extend in a double line as shown in FIG. 2, or the groove may extend in a single line.

The start end 51a of the first score portion 51 is located near the rivet 57, and there is a gap between the start end 51a and the end end 51b of the first score portion 51. The portion between the start end 51a and the end end 51b, in other words, the portion where the first score portion 51 is interrupted, is the first connection portion 55. At the first connection portion 55, the drinking spout piece 53 is not separated from the other portions of the panel portion 41.

The start end 52a of the second score section 52 is located near the rivet 57, and there is a gap between the start end 52a and the end end 52b of the second score section 52. The portion between the start end 52a and the end end 52b, in other words, the portion where the second score section 52 is interrupted, is the second connection section 56. At the second connection section 56, the aroma spout 54 is not separated from the other portions of the panel section 41.

It is preferable that the second connection part 56 is located on the opposite side of the straight line A1 to the first connection part 55. In other words, it is preferable that the first connection part 55 is located in one of the two regions separated by the straight line A1, and the second connection part 56 is located in the other of the two regions. This prevents the first connection part 55 supporting the drinking spout piece 53 that folds down into the beverage can 10 and the second connection part 56 supporting the aroma spout piece 54 that similarly folds down into the beverage can 10 from coming close to each other when the drinking spout 70 and the aroma spout 71 are opened. This prevents extreme variations in the strength of the panel part 41 from occurring after the drinking spout 70 and the aroma spout 71 are opened.

The panel portion 41 may be provided with a structure for increasing the rigidity of the panel portion 41. One example of such a structure is a stepped portion 58. The stepped portion 58 extends, for example, in a ring shape surrounding the drinking piece 53 and the aroma piece 54. The inner region of the stepped portion 58 is recessed relative to the outer region of the stepped portion 58.

Figure 3 shows the planar structure of the tab 60. The tab 60 has an attachment portion 61 that is attached to the panel portion 41. An attachment hole 62 through which the rivet 57 is passed is formed in the center of the attachment portion 61.

The tab 60 further includes a pressing portion 63 connected to the attachment portion 61 and a finger hook portion 64 located on the opposite side of the attachment portion 61 to the pressing portion 63. The pressing portion 63 includes a first end 60a which is one end of the tab 60 in the longitudinal direction, and the finger hook portion 64 includes a second end 60b which is the other end of the tab 60 in the longitudinal direction. The longitudinal direction is the direction in which the pressing portion 63, the attachment portion 61, and the finger hook portion 64 are aligned, and the direction perpendicular to the longitudinal direction is the width direction. The pressing portion 63 has the function of pressing the drinking spout piece 53 and the aroma spout piece 54 when the drinking spout 70 and the aroma spout 71 are opened. The finger hook portion 64 is a portion on which the user's fingers of the beverage can 10 are hooked when the drinking spout 70 and the aroma spout 71 are opened.

The shape of the pressing portion 63 is not particularly limited. For example, the pressing portion 63 has a substantially semicircular shape centered near the mounting hole 62. A separation hole 65 extending along the outer periphery of the mounting portion 61 is formed between the finger hook portion 64 and the mounting portion 61. The separation hole 65 penetrates the tab 60 in its thickness direction, and the finger hook portion 64 and the mounting portion 61 are separated at the separation hole 65. The finger hook portion 64 and the pressing portion 63 are connected on the outside of the mounting portion 61.

A tab hole 66 is formed in the finger hook portion 64 between the separation hole 65 and the second end 60b. The tab hole 66 penetrates the tab 60 in its thickness direction. The formation of the tab hole 66 makes it easy for the user to grasp and lift the finger hook portion 64.

The width of the finger hook portion 64, i.e., the width of the finger hook portion 64, gradually increases toward the second end 60b, and both edges of the finger hook portion 64 in the width direction extend in a curved shape in a plan view. In detail, the width of the finger hook portion 64 gradually increases from the portion beyond the attachment portion 61 on the way from the first end 60a to the second end 60b. As a result, the finger hook portion 64 has a roughly fan-shaped shape in a plan view around the tab hole 66. Furthermore, one edge 64a and the other edge 64b in the width direction of the finger hook portion 64 each have a curved linear shape.

Figure 4 shows the planar structure of the can lid 30. The rivet 57 of the panel portion 41 is passed through the mounting hole 62 of the tab 60, and the upper portion of the rivet 57 is crimped, thereby attaching the tab 60 to the panel portion 41. Therefore, the finger hook portion 64 is located on the opposite side of the pressing portion 63 with respect to the center of the panel portion 41.

Before the beverage can 10 is opened, i.e., when the drinking spout 70 and aroma spout 71 are not open, the tab 60 is positioned so that the first end 60a of the pressing portion 63 of the tab 60 overlaps with the aroma spout piece 54. At this time, the length of the tab 60 is aligned along the direction in which the drinking spout piece 53, the rivet 57, and the aroma spout piece 54 are aligned, and the finger hook portion 64 extends over the drinking spout piece 53. The position of the tab 60 where the first end 60a of the pressing portion 63 is located on the aroma spout piece 54 and where the finger hook portion 64 extends over the drinking spout piece 53 is the initial position of the tab 60.

The tab 60 is attached to the panel portion 41 so as to be rotatable around the rivet 57 at least after the aroma port 71 is opened. Preferably, the tab 60 is fixed in an initial position before the beverage can 10 is opened, and the tab 60 is allowed to rotate after the aroma port 71 is opened. Therefore, it is preferable that the can lid 30 has a structure for fixing the tab 60 in the initial position before the beverage can 10 is opened.

For example, as shown in FIG. 5, a protrusion 59 may be provided on the spout piece 53 at a position that sandwiches the finger hook portion 64 along its width direction. The protrusion 59 restricts the rotation of the tab 60 before the beverage can 10 is opened, i.e., when the tab 60 is arranged along the upper surface of the panel portion 41. Specifically, when the tab 60 tries to rotate around the rivet 57, the finger hook portion 64 gets caught on the protrusion 59, so that the rotation of the tab 60 is suppressed. Once the tab 60 is raised, the finger hook portion 64 is in a state away from the upper surface of the panel portion 41 compared to before the beverage can 10 is opened, so that the tab 60 can rotate without the finger hook portion 64 getting caught on the protrusion 59.

Alternatively, the protrusion 59 may be positioned on the spout piece 53 at a position that overlaps with the finger hook 64 when the tab 60 is in the initial position. The edge of the tab 60 has a shape in which the end of the metal plate that constitutes the tab 60 is bent to the back side, so that the back side of the tab 60 has a step. If the protrusion 59 is positioned at a position that overlaps with the finger hook 64, the protrusion 59 will get caught on this step, thereby preventing the tab 60 from rotating. In this case, once the tab 60 has been raised, the tab 60 can rotate without the finger hook 64 getting caught on the protrusion 59.

The structure for fixing the tab 60 in the initial position before the beverage can 10 is opened is not limited to the above example. For example, the rotation of the tab 60 before the beverage can 10 is opened may be suppressed due to the pressure difference between the inside and outside of the beverage can 10.

Figure 6 shows the side structure of the tab 60 together with the outer shape of the lid plate portion 40 and the can body 20. The end portion including the second end 60b of the finger hook portion 64 is curved in a direction away from the upper surface of the panel portion 41. In detail, the tab 60 extends from the first end 60a along the upper surface of the panel portion 41 and is bent upward on the side of the tab hole 66.

It is preferable that the upper end of the tab 60, i.e., the second end 60b, does not protrude above the upper end of the cover plate portion 40 in the vertical direction. This prevents the tab 60 from getting in the way when multiple beverage cans 10 are stacked during transportation or storage of the beverage cans 10. In addition, in the cover plate portion 40, the panel portion 41 is located at a position recessed from the annular portion 42, and the upper end of the cover plate portion 40 is, in other words, the upper end of the annular portion 42.

[How to use beverage cans]
7 to 10, a method for opening the beverage can 10 and a method for drinking a beverage from the beverage can 10 will be described, and the operation of the beverage can 10 of this embodiment will be described.

When opening the beverage can 10, the user of the beverage can 10 first places his/her finger on the finger hook portion 64 of the tab 60, which is in the initial position, and raises the tab 60. This causes the tab 60 to bend at the boundary between the attachment portion 61 and the pressing portion 63, and the finger hook portion 64 is raised so as to move away from the panel portion 41. As a result, the first end 60a of the pressing portion 63 presses against the aroma spout 54. The end of the finger hook portion 64 is curved back, making it easy to raise the tab 60.

As a result of the pressure applied by the tab 60, the aroma spout piece 54 is separated from the rest of the panel portion 41 at the second score portion 52, and the aroma spout piece 54 is pushed into the interior of the beverage can 10. This opens the aroma spout 71, as shown in FIG. 7.

The user then tilts the tab 60 again to an angle where the first end 60a of the tab 60 does not enter the interior of the aroma port 71, and rotates the tab 60 around the rivet 57 as shown in FIG. 8. The rotation may be clockwise or counterclockwise. At this time, since the width of the finger hook portion 64 increases toward the second end 60b, it is easy to apply force to rotate the tab 60 by hooking a finger on either of the edges 64a, 64b. In particular, since the edges 64a, 64b are curved lines, it is easy to apply force to the tab 60 by running a finger along the edges 64a, 64b.

In addition, because the end of the finger hook 64 is curved, it is easy to hook a finger on the finger hook 64 from the side, which also makes it easier to apply force to rotate the tab 60. Furthermore, by hooking a finger on the curved end of the finger hook 64, the finger is prevented from coming into close proximity with the edge of the scent port 71 when rotating the tab 60, which prevents the finger from accidentally coming into contact with the edge of the scent port 71 and also prevents the user from feeling scared due to the finger coming into close proximity with the edge of the scent port 71.

As shown in FIG. 9, the tab 60 is rotated 180° relative to the initial position. The position at which the tab 60 is rotated 180° from this initial position is the usage position of the tab 60. In the usage position, the first end 60a of the pressing portion 63 is positioned on the drinking piece 53, and the finger hook portion 64 extends over the aroma port 71.

Then, the user places his/her finger on the finger hook 64 of the tab 60 in the usage position and raises the tab 60. This causes the first end 60a of the pressing portion 63 to press the drinking spout piece 53. As a result, the drinking spout piece 53 is separated from the rest of the panel portion 41 at the first score portion 51 and is pushed into the interior of the beverage can 10, opening the drinking spout 70 as shown in FIG. 10. The tab 60 is then tilted down again to complete the opening of the beverage can 10. At this time, the tab 60 is in the usage position and the tab hole 66 is positioned above the aroma hole 71.

As shown in FIG. 10, the user drinks the beverage in the beverage can 10 through the drinking spout 70 with the drinking spout 70 and aroma spout 71 open and the tab 60 in the use position. At this time, the aroma spout 71 is placed in front of the user's nose, sandwiching the tab hole 66. Therefore, the aroma of the beverage in the beverage can 10 can be easily detected by the user through the aroma spout 71. Drinking the beverage while smelling the aroma enhances the flavor of the beverage.

In addition, when the user is drinking a beverage from the drinking spout 70, the aroma port 71 is positioned above the drinking spout 70, preventing the beverage from leaking out of the aroma port 71. This allows the aroma port 71 to function properly as a hole for passing aroma.

As shown in FIG. 10, when the tab 60 and aroma vent 71 are viewed overlapping each other in the usage position, it is preferable that the aroma vent 71 is larger than the tab hole 66 of the tab 60 and does not protrude beyond the outer edge of the tab 60. This causes the entire inside of the tab hole 66 to overlap with the aroma vent 71, making it easier for the aroma of the beverage in the beverage can 10 to reach the user through the aroma vent 71 and preventing the edge of the aroma vent 71 from accidentally coming into contact with the user's nose.

In this embodiment, the drinking spout 70 is opened after the aroma port 71 is opened. Therefore, the user can enjoy the aroma of the beverage before drinking it, and can also enjoy the aroma from the aroma port 71 while opening the drinking spout 70.

In addition, when the drinking spout 70 and aroma spout 71 are opened, a sound is generated. That is, when the beverage can 10 is opened, a sound is generated twice: when the aroma spout 71 is opened and when the drinking spout 70 is opened. Therefore, the difference from the conventional case where only the drinking spout 70 is opened is recognized by the user not only visually and olfactoryly, but also by hearing. Therefore, the difference from the conventional case is clearly recognized by the user, and the uniqueness of the beverage can 10 is strongly impressed on the user.

Furthermore, the sound generated when opening becomes higher the larger the opening. Because the drinking spout 70 is larger than the aroma spout 71, a relatively low sound is generated when the aroma spout 71 is opened for the first time, and a relatively high sound is generated when the drinking spout 70 is opened for the second time. In this way, the sound associated with the opening gets higher in the order of opening, which increases the user's anticipation of drinking from the beverage can 10 and also increases the enjoyment of using the beverage can 10.

The panel unit 41 may have at least one of a marking indicating the difference between the drinking spout 70 and the aroma port 71 and a marking indicating the order in which the drinking spout 70 and the aroma port 71 should be opened. Such a marking may include letters, numbers, symbols such as arrows, pictures, and the like. The marking may be, for example, a convex portion or a groove formed on the panel unit 41. By providing a marking indicating the difference between the drinking spout 70 and the aroma port 71, it becomes easier for the user to understand how to drink the beverage from the beverage can 10. By providing a marking indicating the order in which the drinking spout 70 and the aroma port 71 should be opened, it becomes easier for the user to understand how to open the beverage can 10. In addition, such a marking may include a marking in Braille or the like for the visually impaired.

Figure 11 shows a can lid 30 having an example of the above-mentioned markings. In the example shown in Figure 11, a marking 80 showing a picture of a mouth is provided on the drinking spout piece 53, and a marking 81 showing a picture of a nose is provided on the aroma spout piece 54. These marks 80, 81 are marks that indicate the distinction between the drinking spout 70 and the aroma spout 71. When the tab 60 is in the initial position, the marking 80 on the drinking spout piece 53 is positioned in a position that is visible through the tab hole 66. This allows the user to intuitively understand that the drinking spout 70 is an opening for drinking a beverage by bringing the mouth close to it, and the aroma spout 71 is an opening for smelling the aroma by bringing the nose close to it.

In addition, on the outside of the stepped portion 58, a mark 82 indicating that the beverage contains alcohol is provided in Braille and letters on the side of the drinking spout piece 53, and a mark 83 indicating that the beverage contains aroma is provided in Braille and letters on the side of the aroma spout piece 54. These marks 82, 83 also serve to distinguish between the drinking spout 70 and the aroma spout 71. This allows users, including visually impaired people, to easily understand that the drinking spout 70 is an opening for releasing alcohol, and the aroma spout 71 is an opening for releasing aroma. The mark 82 indicating that the beverage contains alcohol also functions as a mark to inform users that the contents of the beverage can 10 contain alcohol.

Also, on the outside of the step portion 58, opposite the indicators 82 and 83, an indicator 84 is provided that indicates the order in which to open the drinking spout 70 and the aroma vent 71. This indicator 84 indicates the word "OPEN" and numbers indicating the order in which to open the tab 60 on each side of the drinking spout piece 53 and the aroma vent piece 54, and between these letters and numbers, an arrow indicating the rotation direction of the tab 60. This allows the user to easily understand the order in which to open the drinking spout 70 and the aroma vent 71, and also allows the user to easily understand the operation to open the aroma vent 71 following the drinking spout 70, i.e., the operation to rotate the tab 60.

The can lid 30 may have a structure for preventing the tab 60 from rotating from the use position. For example, the rotation direction of the tab 60 may be set to either clockwise or counterclockwise, and a protrusion may be provided on the panel portion 41 that is located at the tip of the finger hook portion 64 in the use position in the rotation direction so that the tab 60 is prevented from rotating in the set direction beyond 180° from the initial position.

The beverage in the beverage can 10 may also be poured from the beverage can 10 into a container such as a glass. At this time, the aroma port 71 functions as a hole through which air enters the interior of the beverage can 10. When air enters the beverage can 10 from the aroma port 71, the beverage is more likely to come out of the drinking spout 70, so that the beverage can be smoothly poured from the beverage can 10 into the container. Furthermore, compared to the conventional case in which the drinking spout 70 functions as both a beverage outlet and an air intake, the amount of air entering the beverage can 10 is more likely to be stabilized by using the aroma port 71, so that the flow rate of the beverage flowing out of the drinking spout 70 can be kept constant from the time the beverage is poured out until it is finished. This makes it possible to prevent the beverage from splashing around inside the container due to a sudden change in the flow rate of the beverage.

As described above, the beverage can 10 and the can lid 30 of this embodiment can provide the following advantages.
(1) The panel portion 41 has a drinking spout piece 53 and a scent spout piece 54, and the tab 60 is attached to the panel portion 41 so as to be rotatable between an initial position in which the pressing portion 63 is disposed on the scent spout piece 54 and a usage position in which the pressing portion 63 is disposed on the drinking spout piece 53. According to this configuration, when the beverage can 10 is opened, the drinking spout 70 and the scent spout 71 are opened based on the lifting and rotation of the tab 60. Therefore, when a user drinks a beverage from the drinking spout 70, the scent spout 71 is disposed in front of the user's nose. Therefore, when the user drinks a beverage, the scent of the beverage in the beverage can 10 is easily delivered to the user through the scent spout 71, thereby enhancing the taste of the beverage.

(2) Before the beverage can 10 is opened, the tab 60 is in the initial position and the pressing portion 63 is positioned on the aroma spout piece 54. This makes it possible to guide the opening method of the beverage can 10 so that the aroma spout 71 is opened before the drinking spout 70. By opening the aroma spout 71 first, the user can enjoy the aroma of the beverage before drinking it, and can also enjoy the aroma from the aroma spout 71 while opening the drinking spout 70.

Furthermore, if the can lid 30 has a structure for fixing the tab 60 in the initial position before the beverage can 10 is opened, it is possible to more accurately guide the opening method in which the aroma port 71 opens before the drinking port 70, and opening can proceed smoothly.

(3) After opening the beverage can 10, the tab 60 is positioned in the usage position, and the tab hole 66 is positioned above the aroma port 71. As a result, when a user drinks a beverage from the drinking spout 70, the finger hook portion 64 of the tab 60 is positioned between the user's nose and the vicinity of the aroma port 71 of the panel portion 41. Therefore, while the aroma from the aroma port 71 reaches the user through the tab hole 66, the user's nose is prevented from entering the aroma port 71, thereby preventing inadvertent contact between the nose and the edge of the aroma port 71.

(4) After opening the beverage can 10, when the tab 60 is in the usage position, when the panel portion 41 and the tab 60 are viewed overlapping, the aroma vent 71 is larger than the tab hole 66 and does not protrude beyond the outer edge of the tab 60. With this configuration, the entire inside of the tab hole 66 overlaps with the aroma vent 71, making it easier for the aroma of the beverage in the beverage can 10 to reach the user through the aroma vent 71, and because the aroma vent 71 does not protrude beyond the outer edge of the tab 60, inadvertent contact between the nose and the aroma vent 71 is effectively prevented.

(5) Two sounds are produced when the aroma opening 71 and the drinking opening 70 are opened. Therefore, the difference from the conventional case where only the drinking opening 70 is opened is recognized by the user not only visually and olfactoryly, but also aurally. Therefore, the difference from the conventional case is clearly recognized by the user, and the uniqueness of the beverage can 10 is strongly impressed on the user.

(6) Because the drinking spout piece 53 and the aroma spout piece 54 are different in size, the pitch of the sound made when the aroma spout 71 is opened differs from the sound made when the drinking spout 70 is opened. This increases the user's interest in opening the beverage can 10.

Furthermore, because the aroma spout piece 54 is smaller than the drinking spout piece 53, when opening the aroma spout 71 first and then the drinking spout 70, the sound associated with the opening gets louder in the order of opening. This increases the user's anticipation of drinking a beverage from the beverage can 10, and further enhances the user's interest.

(7) The width of the finger hook portion 64 of the tab 60 increases toward the second end 60b, i.e., toward the end of the finger hook portion 64 opposite the pressing portion 63. With this configuration, it is easier to apply force to rotate the tab 60 by hooking a finger on the edge of the finger hook portion 64. This reduces the burden on the user when rotating the tab 60, making it easier for women with long nails, or children and elderly people with weak strength, to open the beverage can 10.

(8) The end of the finger hook 64 opposite the pressing portion 63 is curved in a direction away from the panel portion 41. This configuration makes it easier to hook a finger on the finger hook 64 from the side, making it easier to apply force to rotate the tab 60. Furthermore, by hooking a finger on the curved end of the finger hook 64, the finger is prevented from coming into close proximity with the edge of the scent port 71 when rotating the tab 60, preventing the finger from accidentally coming into contact with the edge of the scent port 71 and reducing the user's sense of fear.

(9) The panel unit 41 has markings that indicate the difference between the drinking spout 70 and the aroma vent 71, making it easier for users to understand how to drink from the beverage can 10. In addition, the panel unit 41 has markings that indicate the order in which to open the drinking spout 70 and the aroma vent 71, making it easier for users to understand how to open the beverage can 10.

[Modification]
The above embodiment may be modified as follows. The following modifications may be combined with each other.

- The shape of the finger hook portion 64 of the tab 60 may be different from that of the above embodiment. For example, the width of the finger hook portion 64 may be constant, and the edges 64a, 64b of the finger hook portion 64 may be straight or bent. In addition, the end of the finger hook portion 64 may not be curved, and the entire tab 60 may extend along a single plane.

- As long as the panel portion 41 has a drinking spout piece 53 and a scent spout piece 54, the size relationship between the drinking spout piece 53 and the scent spout piece 54 may be different from that of the above embodiment. For example, even if the drinking spout piece 53 and the scent spout piece 54 are the same size, or even if the scent spout piece 54 is larger than the drinking spout piece 53, the above effects (1) to (5) and (7) to (9) can be obtained.

The order in which the drinking spout 70 and the aroma vent 71 are opened may be different from that in the above embodiment. The position of the tab 60 before and after opening the beverage can 10 may also be different from that in the above embodiment. Regardless of the order of openings or the position of the tab 60, the effect of (1) above can be obtained as long as two openings, the drinking spout 70 and the aroma vent 71, are formed when the beverage can 10 is opened.
