The best mode for carrying out the present invention will be described below in detail with reference to the accompanying drawings.
FIG. 1 is a view showing a container according to an embodiment of the present invention. In addition, in this figure, what is called a 2 piece can is illustrated. FIG. 1A shows a front view, and FIG. 1B shows a top view.

As shown in FIG. 1A, the container 20 in the present embodiment is composed of a base 21 filled with a beverage and a lid member 22 attached to the top of the base 21.
The base body 21 as an example of a cylindrical body and a main body has a cylindrical side portion 211 and a bottom portion 212 formed integrally with the side portion 211.
The lid member 22 is formed in a disc shape and is fixed to the upper portion of the base body 21 by so-called winding.

Here, the cover member 22 includes a circular substrate 41 and an opening tab 42 as shown in FIG.
The substrate 41 is formed of a circular metal plate. And this board | substrate 41 is being fixed to the upper edge part of the side part 211 by what is called winding tightening. In addition, the substrate 41 is formed with a planned opening area (opening area) 44 that is opened when a drinking mouth is formed at a position shifted from the center (an eccentric position). Further, a score (scheduled fracture line) 41 a surrounding the planned opening area 44 is formed on the substrate 41.

The opening tab 42 is a rigid plate-like member, and is fixed to the substrate 41 by a rivet 43 provided at the center of the substrate 41. In other words, the opening tab 42 includes a fixing portion 42 a that is fixed to the substrate 41 via the rivet 43. Further, the opening tab 42 includes a ring portion 42b extending along the substrate 41 from the fixing portion 42a.
Here, the fixing portion 42 a is disposed so as to overlap the planned opening region 44. The ring part 42b extends in a direction away from the score 41a.
In the present embodiment, the ring portion 42b is provided on one side of the container 20 with respect to the place where the rivet 43 is provided, and the planned opening area 44 is the other side of the container 20 with respect to the place where the rivet 43 is provided. On the side.
More specifically, the opening tab 42 and the scheduled opening area 44 are arranged on the same line.

The ring portion 42b is an annular knob portion having a ring hole 42c. Then, when the finger is placed on the tip of the ring part 42b and pulled up, the tip of the fixed part 42a moves downward with the rivet 43 as a fulcrum. Thereby, the score 41a is broken by the so-called lever principle. As a result, the planned opening area 44 is opened, and the beverage as the contents can be poured out.
Here, part or all of the ring portion 42 b is preferably formed in a state of being separated from the substrate 41. In this way, a space in which a finger can enter is secured between the ring portion 42b and the substrate 41, and it is easy to hook and raise the ring portion 42b.

  Moreover, in the container 20 in this embodiment, the design including a character, a figure, etc. is printed on the side part 211 of the base 21. The design includes a first identification mark 23a and a second identification mark 23b for distinguishing from other products such as a trade name and a trade name (in this specification, hereinafter, simply referred to as "identification mark 23"). "). Here, the first identification mark 23 a and the second identification mark 23 b are arranged in a state where the phase is shifted by 180 ° in the circumferential direction of the container 20. The first identification mark 23a and the second identification mark 23b may be the same or different.

Next, the relationship between the planned opening area 44 and the identification mark 23 will be described.
In the container 20 according to the present embodiment, the identification mark 23 and the planned opening area 44 are arranged with a predetermined positional relationship. Although details will be described later, in the present embodiment, the positions of the base 21 and the lid member 22 are controlled so that the identification mark 23 and the scheduled opening area 44 have a predetermined positional relationship.

The positional relationship between the identification mark 23 and the planned opening area 44 will be specifically described. In this embodiment, the identification mark 23 and the planned opening area 44 are in a state where the phase is shifted by 90 ° in the circumferential direction of the container 20. Has been placed.
Further, with reference to FIG. 5B, when the first identification mark 23a faces in one direction (downward in the figure), the planned opening region 44 is in a direction perpendicular to the one direction (leftward in the figure). The base body 21 and the lid member 22 are disposed so as to be disposed along the line. In addition, when the second identification mark 23b faces one direction (upward in the figure), the planned opening area 44 is arranged in a state along the direction (left direction in the figure) perpendicular to the one direction. The base 21 and the lid member 22 are arranged.

More specifically, when the axis of the container 20 is used as a reference, the planned opening region 44 is arranged along one direction from the axis toward the side portion 211. On the other hand, the first identification mark 23a and the second identification mark 23b are arranged so as to face a direction orthogonal to the one direction.
More specifically, the planned opening area 44 is arranged on a straight line from the axial center of the container 20 toward the side portion 211, and the first identification mark 23a and the second identification mark 23b are straight lines orthogonal to the straight line. It is arranged on a straight line passing through 20 axes. In other words, the first identification mark 23 a and the second identification mark 23 b are arranged so as to face in a direction orthogonal to the virtual line when assuming a virtual line passing through the center of the lid member 22 and the planned opening area 44. Part 211 is attached.
Further, when a straight line passing through the scheduled opening area 44 and the opening tab 42 is used as a reference line, the first identification mark 23a is provided in an area on the right side of the reference line, and the second identification mark 23b is provided on the reference line. Is also provided in the left region.

Here, FIG. 2 is a diagram showing a state of the container 20 when the internal beverage is drunk.
In the container 20 according to the present embodiment, the identification mark 23 and the planned opening area 44 are arranged with the above positional relationship. For this reason, an opening is formed in the planned opening area 44, and when the beverage is drunk through this opening (drinking mouth), the second identification mark 23b is directed to the side as shown in FIG. Although not shown, the first identification mark 23a also faces sideways.

  Here, the promotion of products such as beverages is usually performed by television commercials or the like, but the advertising effect is also achieved by placing the identification mark 23 at a position visible to a third party when the beverage is drunk. Can occur. In the container 20 in the present embodiment, when the beverage is drunk, the identification mark 23 faces sideways as described above, and the identification mark 23 is arranged at a position where the third person can recognize. For this reason, the advertising effect can be produced. In other words, since the identification mark 23 is not located on the drinker side, and the identification mark 23 is located at a position that can be recognized by a third party, an advertising effect can be produced.

In the above description, the case where the identification mark 23 faces to the side has been described as an example. However, when a beverage is drunk, the advertisement as described above may be used even if the identification mark 23 faces the side opposite to the drinker side. An effect can be produced. That is, even if the identification mark 23 is attached to the side opposite to the scheduled opening area 44, that is, the ring portion 42b side, it is possible to produce an advertising effect. In other words, even if the identification mark 23 is attached to the side opposite to the side where the planned opening area 44 is arranged eccentrically, it is possible to produce an advertising effect.
Alternatively, when the identification mark 23 is to be shown on the drinker side, it may be attached to both the planned opening area 44 side and the opposite side, as shown in FIG. It is also possible to attach it upside down to make it easier to understand. That is, the identification mark 23 (second identification mark 23b) on the opposite side can be attached upside down.

  Here, the container 20 is generally often held by the right hand. This is because there are generally more right-handed than left-handed. As a result, even if the identification mark 23 faces sideways, the identification mark 23 attached to the place held by the right hand may be hidden by the right hand. For this reason, it is more preferable that the identification mark 23 in the container 20 is provided at a position that is not hidden even if it is held by the right hand. More specifically, it is preferably provided at the position of the second identification mark 23b in FIG. In other words, after the lid member 22 is positioned above the base body 21 (see FIG. 1A), the container is opened from the side where the planned opening area 44 is arranged eccentrically (left side of FIG. 1A). When viewing 20, it is desirable to provide an identification mark 23 in the left region of the container 20. In this case, even if the container 20 is held by the right hand, the identification mark 23 is exposed to the outside without being hidden by the right hand.

Next, the manufacturing process of the container 20 will be described.
FIG. 3 is a diagram illustrating a manufacturing process of the container 20.
The container 20 shown in FIG. 1 can be manufactured, for example, by the manufacturing process shown in FIG. Specifically, it can be manufactured by a manufacturing process including a beverage filling process 301 in which a beverage is filled, a positioning process 302, and a fixing process 303.

Here, the beverage filling step 301 is a step of filling the beverage as the contents into the inside of the base body 21 through the opening provided in the upper part of the base body 21.
The positioning step 302 is a step of positioning the base body 21 and the lid member 22. Specifically, the base 21 and the lid member 22 are positioned so that the identification mark 23 and the planned opening area 44 have the above positional relationship.

FIG. 4 is a diagram showing a positioning mode in the positioning step 302.
In the positioning step 302, for example, the position of the identification mark 23 attached to the base 21 is detected, and the lid member 22 is rotated in the circumferential direction based on the detection result (see the arrow 4A in the figure). The base 21 and the lid member 22 are positioned so that the planned area 44 has the above positional relationship. Thereafter, the lid member 22 is placed on the upper portion of the base 21.

  Here, the detection of the position of the identification mark 23 is performed by, for example, an image sensor such as a CCD arranged around the container 20 and a computer (analyzing means) for analyzing data acquired by the image sensor. be able to. Further, the rotation of the lid member 22 controls, for example, a holding unit (not shown) that sucks and holds the lid member 22, a drive source (not shown) such as a motor that rotates the holding unit, and the drive source. It can be performed by a control means constituted by a computer.

  By the way, when the lid member 22 is held by the holding portion, it is necessary to align the direction of the lid member 22. That is, it is necessary to align the position of the planned opening region 44 in the circumferential direction of the lid member 22. Similar to the above, this alignment is performed by an image pickup device such as a CCD, a computer (analyzing means) for analyzing data acquired by the image pickup device, and a rotation for rotating the lid member in the circumferential direction based on the analysis result by the computer Means. The rotating means includes, for example, a holding portion (not shown) that sucks and holds the lid member 22, a driving source (not shown) such as a motor that rotates the holding portion, and the driving source. It can be performed by a control means constituted by a computer for controlling the above.

  The position of the identification mark 23 may be detected not only by detecting the identification mark 23 but also by detecting an identification mark printed in a state having a predetermined positional relationship with the identification mark 23, for example. Further, when a bar code having a predetermined positional relationship with the identification mark 23 is included in the symbol printed on the side portion 211, it can be performed based on the detection result of the bar code.

Returning to FIG. 3A, the manufacturing process of the container 20 will be further described.
The base 21 and the lid member 22 that have been positioned in the positioning step 302 are fixed in the fixing step 303. In the fixing step 303, the base 21 and the lid member 22 are fixed by bending the upper edge of the base 21 and the outer edge of the lid member 22. That is, the base 21 and the lid member 22 are fixed by so-called winding.

The container 20 can also be manufactured by the manufacturing process shown in FIG.
In the manufacturing process shown in FIG. 3B, a positioning process 401, a beverage filling process 402, and a fixing process 403 are provided as described above. However, in the manufacturing process shown in the figure, a beverage filling process 402 is provided after the positioning process 401. In other words, the order of the processes is partially changed.

Here, in the positioning step 401 in FIG. 3B, the base member 21 is not rotated but the base member 21 is rotated in the circumferential direction and the base member 21 is stopped in a state where the identification mark 23 faces a predetermined direction ( Positioning). The base 21 can be rotated and stopped by detecting the identification mark 23 and stopping the driving source such as a motor, as described above.
Then, the base body 21 is transported to the beverage filling process 402 while maintaining the posture of the base body 21 (while maintaining the state where the identification mark 23 faces a predetermined direction). Then, after filling the beverage in the beverage filling step 402, the base 21 is further transported to the fixing step 403 while maintaining the posture.
In the fixing step 403, the lid member 22 is fixed. Since the base 21 has already been positioned in the positioning step 401, in the fixing step 403, the lid member 22 that is stacked with its orientation aligned is simply placed on the base 21 and fixed to the base 21. .

Next, another form of the container will be described.
FIG. 5 is a view showing another embodiment of the container. 1A is a front view and FIG. 1B is a rear view. FIG. 3C is a top view.

The container 30 shown in this figure is a so-called three-piece can, and is composed of three members: a body portion 31, a lid member 32, and a bottom member 33.
The barrel portion 31 as another example of the cylindrical body is formed in a cylindrical shape. Here, the body portion 31 is formed by performing a welding process after a plate-like member (blank material) is formed into a cylinder. For this reason, as shown to the same figure (B), the welding part 34 is provided along the height direction.
The lid member 32 is formed in a disc shape, and is fixed to the upper edge portion of the body portion 31 formed in a cylindrical shape by so-called winding. In addition, the lid member 32 includes a substrate 41, an opening tab 42, and the like, similar to the lid member 22 shown in FIG. In addition, about the function similar to the cover member 22 shown in FIG. 1, the same code | symbol is used and the description is abbreviate | omitted here.
The bottom member 33 is also formed in a disc shape, and is fixed to the lower edge portion of the body portion 31 formed in a cylindrical shape by so-called winding.

In the container 30 according to the present embodiment, the design including characters and figures is printed on the body portion 31. The symbol includes an identification mark 23 for distinguishing it from other products such as a product name and a trade name. Note that the container 30 in this embodiment is in a state in which one identification mark 23 is provided unlike the container 20 shown in FIG.
Further, also in the container 30 in this embodiment, the identification mark 23 and the planned opening area 44 are arranged in a state having a predetermined positional relationship. That is, the position control of the trunk portion 31 and the lid member 32 is performed so that the identification mark 23 and the scheduled opening area 44 have a predetermined positional relationship.

The positional relationship between the identification mark 23 and the planned opening area 44 will be specifically described with reference to FIG. 5C. The phase of the identification mark 23 and the planned opening area 44 is 90 ° in the circumferential direction of the container 30. Arranged in a shifted state.
Further, when the identification mark 23 faces in one direction (left direction in the figure), the planned opening region 44 is arranged in a state along the direction orthogonal to the one direction (downward direction in the figure). The trunk | drum 31 and the cover member 32 are arrange | positioned.

More specifically, when the axial center of the container 30 is used as a reference, the planned opening region 44 is arranged along one direction from the axial center toward the body portion 31 (see FIG. 1A). On the other hand, the identification mark 23 is arranged so as to face a direction orthogonal to this one direction.
More specifically, the planned opening area 44 is arranged on a straight line from the axial center of the container 30 toward the body portion 31, and the identification mark 23 is a straight line orthogonal to this straight line and passing through the axial center of the container 30. Is arranged.
Further, when a straight line passing through the planned opening area 44 and the opening tab 42 is used as a reference line, the identification mark 23 is provided in an area on the left side of the reference line.

  For this reason, also in the case of the container 30 in this embodiment, when the beverage is drunk through the opening (drinking mouth) as in FIG. 2, the identification mark 23 faces sideways. Even when the container 30 is held by the right hand, the identification mark 23 is arranged at a position where the identification mark 23 is not hidden and can be recognized by a third party.

Next, a method for manufacturing the container 30 will be described.
FIG. 6 is a diagram illustrating an example of the manufacturing process of the container 30.
The container 30 can be manufactured by a manufacturing process similar to the above manufacturing process of the container 20.
That is, as shown to FIG. 6 (A), it can manufacture by the drink filling process 501, the positioning process 502, and the cover member fixing process 503 with which a drink is filled. In addition, although illustration is abbreviate | omitted, before the drink filling process 501, the fixing process which fixes the trunk | drum 31 and the bottom member 33 by winding is provided. Hereinafter, in this specification, what was formed by this fixing process may be called a "can body."

The beverage filling step 501 is a step of filling the beverage, which is the contents, into the inside of the can through the opening in the upper portion of the can, as described above.
The positioning step 502 is a step of positioning the can and the lid member 32 in the same manner as described above. Specifically, the can and the lid member 32 are positioned so that the identification mark 23 and the planned opening area 44 have the above positional relationship.

FIG. 7 is a view showing a positioning mode in the positioning step 502.
In the positioning step 502, the position of the identification mark 23 attached to the can body (body 31) is detected, and the lid member 32 is rotated in the circumferential direction based on the detection result (see the arrow 7A in the figure). The can body and the lid member 32 are positioned so that the opening 23 and the planned opening area 44 have the above positional relationship. Thereafter, the lid member 32 is placed on the upper portion of the can body.
The position of the identification mark 23 can be detected by the same method as described above. The lid member 32 can be rotated by the same method as described above.

Returning to FIG. 6A, the manufacturing process of the container 30 will be further described.
The lid member 32 that has been positioned in the positioning step 502 is fixed to the can in the lid member fixing step 503. Here, in the lid member fixing step 503, the upper edge portion of the trunk portion 31 and the outer edge portion of the lid member 32 are bent to fix the trunk portion 31 and the lid member 32. That is, the body 31 and the lid member 32 are fixed by winding. Thereby, the container 30 filled with the beverage is completed.

  Here, the container 30 can also be manufactured by a manufacturing process similar to the manufacturing process shown in FIG. That is, it can also be manufactured by a manufacturing process including a positioning process 601, a beverage filling process 602, and a lid member fixing process 603 (see FIG. 6B).

In the positioning step 601, similarly to the above, the lid member 32 is not rotated, but the can body is rotated in the circumferential direction to stop (position) the identification mark 23 in a predetermined direction. In addition, rotation of a can can be performed by rotationally driving the roll-shaped member arrange | positioned in contact with the outer peripheral surface of the trunk | drum 31, for example. Further, the can body can be stopped based on the detection result of the identification mark 23 as described above.
Incidentally, irregularities are usually formed in the welded portion 34 (see FIG. 5B). For this reason, the position of the identification mark 23 can be detected based on the unevenness detection result. In addition, this unevenness | corrugation detection can be performed by rotating a can body while making a contact-type sensor contact the outer peripheral surface of a can body.

Thereafter, the can body is fixed so as not to rotate in the circumferential direction, and the can body is transported to the beverage filling step 602 while maintaining the posture (while maintaining the state where the identification mark 23 faces the predetermined direction). . Then, after filling the beverage in the beverage filling step 602, the can body is further conveyed to the lid member fixing step 603 while maintaining the posture.
Then, the lid member 32 is fixed in the lid member fixing step 603. In addition, since the positioning of the can body has already been performed in the positioning step 601, in the lid member fixing step 603, the lid member 32 that is loaded with the orientation aligned is simply placed on the top of the can body and fixed to the can body. Is done.

In the above description, the manufacturing process in which the bottom member 33 is first fixed to the body portion 31 and the lid member 32 is fixed later is described as an example. On the other hand, it is also possible to employ a manufacturing process in which the lid member 32 is first fixed to the body portion 31 and the bottom member 33 is fixed later.
FIG. 8 is a view showing another example of the manufacturing process of the container 30. FIG. 9 illustrates a part of the manufacturing process of the container 30.
As shown in FIG. 8, the container 30 can be manufactured by a positioning step 701, a fixing step 702, a beverage filling step 703 in which a beverage is filled, and a bottom member fixing step 704.
