Thermosetting resins include phenol-formaldehyde resin, furan-formaldehyde resin, xylene-formaldehyde resin, ketone-formaldehyde resin, amino resin, urea formaldehyde resin, melamine-formaldehyde resin, alkyd resin, unsaturated polyester resin, epoxy resin ( Examples: novolac type epoxy resin, bisphenol type epoxy resin), bismaleimide resin, triallyl cyanurate resin, thermosetting acrylic resin, silicone resin, oily resin and the like are used.

  Further, a composition of a thermosetting resin and a thermoplastic resin may be used. In this case, a vinyl chloride-maleic acid-vinyl acetate copolymer, an acrylic polymer, a saturated polyester resin, or the like is used as the thermoplastic resin. These resins can be used singly or in combination of two or more. Moreover, well-known acid catalysts, such as toluenesulfonic acid and benzenesulfonic acid, may be added to these resin compositions as needed. When using an acid catalyst, it is desirable to add the acid catalyst in an amount of 0.5 to 1% by mass based on the resin. Of these resins, it is particularly desirable in terms of coating film performance to use a composition of a melamine-formaldehyde resin and a saturated polyester resin or a composition of a thermosetting acrylic resin and a melamine-formaldehyde resin.

  On the other hand, as the ultraviolet curable resin, for example, a cationic curable resin, a radical curable resin, or the like is used. As the cationic curable resin, a composition of an ultraviolet curable epoxy resin and a cationic photopolymerization catalyst is used.

  Moreover, in the coating material used for the topcoat layer 52, you may add a crosslinking agent and a sensitizer to said resin as needed. As the crosslinking agent, various polyols (eg, ε-caprolactone triol) and the like are used. A thioxanthone derivative or the like is used as the sensitizer. Furthermore, natural, petroleum, or synthetic wax agents may be added alone or in combination as a wax component to the paint used for the top coat layer 52 in order to compensate for slippage. Further, various silicone oils may be added as a leveling agent for the surface of the topcoat layer 52 and / or to further improve the stability in the paint state and to impart initial slipperiness to the topcoat layer 52. good.

An example of the composition of the ink layer 51 and the topcoat layer 52 is as follows.
[Topcoat layer 52]
Resin component: 30% polyester, 13% acrylic, 55% amino, 2% epoxy
Wax: Petroleum 0.3%, Natural 1%, Synthetic 0.2% (based on resin component)
Silicone oil (mixed): 0.15% (based on resin component)
Surface tension: 33 mN / m
Thickness: 5μm
[Ink layer 51] (repellent ink)
Main resin: Alkyd resin Pigment: TiO ₂
Surface tension: 28 mN / m
Thickness: 2μm

  The above is an example of a method for forming the second region R2. For example, the second region R2 may be formed by using a technique disclosed in Japanese Patent Application Laid-Open No. 2002-361172. That is, the second region R <b> 2 may be formed by forming irregularities by agglomerating the coating material forming the top coat layer 52 in the form of spots on the surface of the ink layer 51. Moreover, the crater-like unevenness | corrugation of 2nd area | region R2 can be formed by forming the ink layer 51 using what is called foaming ink containing the foaming agent. Note that the unevenness of the second region R2 caused by the coating material in this patent is on the order of 3 to 10 μm at the maximum depth, and a normal coating paint has a smoothness of about 1 μm or less. The surface is referred to as a first region R1.

Next, the surface state of the first region R1 will be described with reference to FIG.
As shown in FIG. 4D, in the first region R1, a topcoat layer (outermost layer) 52 having a surface smoother than the topcoat layer 52 in the second region R2 is formed on the surface of the ink layer 51. Is provided.

  Here, the ink layer 51 in the first region R <b> 1 is formed using an ink (ordinary ink) that does not repel the paint forming the top coat layer 52. In other words, the ink that forms the ink layer 51 is an ink whose surface tension is equal to or higher than the surface tension of the paint that forms the topcoat layer 52. Therefore, in the first region R1, the paint that forms the topcoat layer 52 is not repelled, and the surface of the topcoat layer 52 is smoother than the topcoat layer 52 in the second region R2. The basic composition of the ink that forms the ink layer 51 is the same as described above. The basic composition of the paint for forming the top coat layer 52 is the same as described above.

  Moreover, the can 20 in this embodiment has the identification mark 23 for identifying with other goods, such as a brand name and a brand name, on the outer surface (outer peripheral surface) as mentioned above. Here, the identification mark 23 is formed in the first region R1. The identification mark 23 is formed by the ink layer 51.

Next, the operation of the can body 20 in the rotation mechanism 30 will be described.
FIG. 11 is a view for explaining the operation of the can 20 in the rotation mechanism 30.
As shown in the figure, the can body 20 placed on the placement portion 31 on the upstream side in the transport direction of the can body 20 is provided with a slope in the left-right direction and a slope in the front-rear direction with respect to the placement surface 31A. Then, it moves forward while being guided by the resistance applying portion 33 (see reference numeral 11A). At this time, if the first region R1 is in contact with the resistance applying portion 33, slippage between the first region R1 and the resistance applying portion 33 is suppressed (a drag is applied to the first region R1), The can body 20 moves forward while rotating clockwise (see reference numerals 11A and 11B).

  And if 2nd area | region R2 will be in the state which contacts resistance provision part 33 like code | symbol 11C, a slip will arise between 2nd area | region R2 and resistance provision part 33, and rotation of the can 20 will stop. Thereafter, the can 20 moves (slides) toward the front while being guided by the resistance applying portion 33. Thereby, the can body 20 that has reached the front of the rotating mechanism 30 is in a state in which the identification mark 23 faces rearward (upstream side in the moving direction). In addition, in the present embodiment, the second region R2 and the identification mark 23 are arranged with a predetermined positional relationship determined in advance as described above. More specifically, when the second region R2 is directed to the left side (one direction), the identification mark 23 is arranged to face backward (a direction intersecting one direction, a direction perpendicular to the one direction). Yes. For this reason, when the second region R2 comes into contact with the resistance applying portion 33, the identification mark 23 faces rearward.

  In FIG. 11, the first roller row 311 and the second roller row 312 (see FIG. 9) are not shown. Here, when 2nd area | region R2 contacts the resistance provision part 33, 2nd area | region R2 and the resistance provision part 33 contact in the state close | similar to a point contact. In other words, the contact area between the second region R2 and the resistance applying portion 33 is reduced. For this reason, it is considered that the slip occurs between the second region R2 and the resistance applying portion 33.

  In the rotation mechanism 30 in the present embodiment, as described above, the roll-shaped member 314 included in the second roller row 312 (see FIG. 9) is fixed so as not to rotate. For this reason, the roll-shaped member 314 included in the second roller row 312 imparts resistance against movement to the moving can body 20. Here, in the configuration of the present embodiment, when no drag is applied from the second roller row 312 to the can body 20, the can body 20 is in contact with the second region R2 and the resistance applying portion 33. There is a possibility of rotating. That is, there is a possibility that unintended rotation of the can body 20 may occur due to the drag applied from the resistance applying unit 33 to the second region R2. For this reason, in the present embodiment, the roll member 314 included in the second roller row 312 is used to provide a drag force to the can body 20 to suppress the unintended rotation. In addition, a drag is applied to a portion of the can body 20 that is located on the opposite side of the portion that contacts the resistance applying portion 33, and excessive rotation of the can body 20 is suppressed.

Here, FIG. 12 is a view showing another embodiment of the rotating mechanism 30. In FIG.
In the rotation mechanism 30 in this figure, the inclination in the front-rear direction of the rotation mechanism 30 is given to the mounting portion 31, but the inclination in the width direction of the rotation mechanism 30 is not given. Moreover, in the rotation mechanism 30 in this figure, the several roll-shaped member 314 provided in 31 A of mounting surfaces is arrange | positioned incline with respect to the front-back direction (movement direction of the can body 20) of the rotation mechanism 30. As shown in FIG.

  More specifically, when a virtual line (see reference numeral 8A) orthogonal to the rotation axis of the roll-shaped member 314 is assumed, each of the roll-shaped members 314 intersects the front-rear direction of the rotation mechanism 30. It is arranged so as to be inclined. In addition, each of the roll-shaped members 314 is arranged such that the imaginary line is inclined with respect to the front-rear direction of the rotation mechanism 30. More specifically, each of the roll-shaped members 314 is disposed so as to be inclined such that the direction in which the virtual line is directed is on the side where the resistance applying portion 33 is provided. For this reason, in the rotating mechanism 30 shown in FIG. 12, the can body 20 is moved toward the resistance applying portion 33 by the roll-shaped member 314 arranged to be inclined while trying to move toward the front of the rotating mechanism 30. .

  Next, a method for forming the first region R1 and the second region R2 formed in the can body 20 will be described in more detail. 1st area | region R1 and 2nd area | region R2 can be formed in the printing process included in the manufacturing process of the can 20 which is a 2 piece can, for example. In more detail, it can form using the printing machine installed in the printing process.

Here, FIG. 13 is a diagram illustrating a printing machine that performs printing on the can 20.
A printing machine 500 shown in the figure is a printing machine that performs so-called offset printing. The printing machine 500 has a blanket cylinder 510, a printing plate corresponding to a pattern, and an ink application device 520 that applies ink to form the ink layer 51 to the blanket cylinder 510, a support roll 530, and the top coat layer 52. A paint application device 540 for applying paint is provided.

  The blanket cylinder 510 is formed in a disc shape and rotates in one direction. The blanket cylinder 510 has a plurality of blankets (transferred portions) 511 on the outer peripheral surface. In addition, the blanket cylinder 510 transfers the ink transferred from the printing plate in the ink applicator 520 to the blanket 511 to the base can body that is the base of the two-piece can at the transfer portion Te and transfers the ink to the base can body. A symbol including the identification mark 23 is formed.

  A plurality of ink applicators 520 are provided for each color along the circumferential direction of the blanket cylinder 510. Each ink coating device 520 includes a printing cylinder 522 that contacts the blanket 511 of the blanket cylinder 510, and an ink supply device 521 that supplies ink to the outer peripheral surface of the printing cylinder 522. Here, the printing cylinder 522 has the above printing plate on the outer peripheral surface, and transfers the ink supplied by the ink supply device 521 to the blanket 511. As a result, ink is placed on the surface of each blanket 511. Specifically, ink is sequentially placed from each of the printing cylinders 522 on each surface of each blanket 511 and assigned to each region assigned to each printing cylinder 522. As a result, an ink image corresponding to the design is formed on the surface of each blanket 511. The ink image moves to the transfer portion Te as the blanket cylinder 510 rotates, and is transferred to the outer peripheral surface of the raw can body rotating in the circumferential direction. As a result, the ink layer 51 is formed.

  The support roll 530 is disposed at a position opposite to the blanket cylinder 510 and rotates in one direction, and conveys the raw can body that has moved from a not-shown washer process to the transfer unit Te. Further, the support roll 530 conveys the raw can body that has moved from the washer process to the transfer unit Te in a rotated state. The coating material coating device 540 applies the coating material to the outer peripheral surface of the element can body (element can body on which the ink layer 51 is formed) to which the ink image is transferred. As a result, the top coat layer 52 is formed.

  Here, when such a printing machine 500 is used, by placing ink having a function of repelling paint from the printing cylinder 522 in charge of the ink layer 51 in the second region R2 on the blanket 511, A surface difference can be formed between the first region R1 adjacent to the second region R2. In addition, formation of 2nd area | region R2 using the said foaming ink can be performed by mounting foaming ink on the blanket 511 from the cylinder 522 for printing which takes charge of the ink layer 51 in 2nd area | region R2. Further, the formation of the second region R2 using the ink for aggregating the paint is performed by placing the ink for aggregating the paint on the blanket 511 from the printing cylinder 522 in charge of the ink layer 51 in the second region R2. It can be carried out.

  By the way, the same color portion on the outer peripheral surface of the can body 20 is usually supplied with ink from a common (single) printing cylinder 522. However, in the present embodiment, ink is supplied from different printing cylinders 522 even if there are portions of the same color in the first region R1 and the second region R2. That is, the same color portion in the first region R1 is supplied with ink from one printing cylinder 522, and the same color portion in the second region R2 is different from the one printing cylinder 522 in another printing cylinder 522 ( Ink is supplied from a printing cylinder 522) that supplies repelling ink.

  Further, when a pattern using a plurality of colors is present over a wide range over the entire circumference of the can 20, it is necessary to prepare a larger number of printing cylinders 522 than in normal printing. That is, for example, in order to form a pattern in the first region R1, it is necessary to prepare a plurality of printing cylinders 522 first. Then, it is necessary to further prepare a plurality of printing cylinders 522 for forming a pattern in the second region R2.

Here, in order to prevent an increase in the printing cylinder 522 as described above, a form as shown in FIG. 14 (a diagram showing another form of the can body 20) may be adopted. 1A shows a front view of the can body 20, and FIG. 1B shows a rear view of the can body 20. FIG.
As shown in the figure, for example, the second region R2 can be provided on the bottom side of the can 20. More specifically, it can be formed as a band having a width along the circumferential direction of the can body 20 and slightly larger than the width of the resistance applying portion 33. If it demonstrates in detail, 2nd area | region R2 can make the length in the circumferential direction of the can body 20 into 1/4 of the perimeter of the can body 20. FIG. In the case of such a form, even if a pattern using a plurality of colors exists over the entire circumference of the can 20, it is only necessary to add one printing cylinder 522 for forming the second region R <b> 2. . In other words, it is not necessary to prepare a large number of printing cylinders 522 as described above.

  In the above description, the sliding resistance is reduced by providing irregularities in the second region R2, but the sliding resistance may be reduced by applying or applying a fluororesin or the like to the second region R2. In this case, it is more convenient to apply a Teflon (registered trademark) processed tape or the like. Similarly, fluororesins (PTFE, PFA, PVDF, etc.) and their tapes, or film tapes with low frictional resistance, such as ultra high molecular weight polyethylene films, can be used.

  Furthermore, the coating material for forming the topcoat layer 52 in the second region R2 may be a so-called mat coating material, thereby providing the second region R2 with unevenness and reducing the sliding resistance. In this case, it is necessary to paint differently. That is, it is necessary to apply a mat paint to the second region R2, and apply a paint other than the mat paint to the first region R1. In addition, the matte paint may be further applied to the surface of the topcoat layer 52 in the second region R2 to give unevenness to the second region R2, and the sliding resistance in this region may be reduced. In addition, the ink layer 51 in the second region R2 may be formed by repelling ink, and the top coat layer 52 may be formed on the surface of the ink layer 51 using a mat paint.

  Here, the mat paint is a paint that contains particles such as glass, silica, and resin that scatter light and has a lower gloss than a normal paint. Since the mat paint contains particles such as glass, silica, and resin as described above, irregularities are formed on the surface thereof. For this reason, even when the mat paint is used, the sliding resistance between the resistance applying portion 33 and the second region R2 is reduced, and the above-described slip can be generated.

  Further, for example, after the top coat layer 52 in the first region R1 and the second region R2 is formed with a mat paint, the paint for smoothing the surface of the first region R1 (for example, the glass or the like is not included). A paint) may be applied. That is, after applying the mat paint to make the entire circumference of the can 20 easy to slip, the first area R1 may be coated with a paint that smoothes the surface to make the first area R1 difficult to slip. Further, for example, after the topcoat layer 52 in the first region R1 and the second region R2 is formed with a mat paint, the above-described Teflon (registered trademark) tape or seal having a smaller friction coefficient than the topcoat layer 52, for example. Or the like may be attached to the second region R2. Further, as shown in FIG. 15 (a diagram showing another embodiment of the can body 20), the tape TA in which the first region R1 and the second region R2 are formed by printing or the like is attached to the can body 20, The first region R <b> 1 and the second region R <b> 2 can be imparted to the outer peripheral surface of the can body 20 regardless of the coating state of the can body 20.

  In the above description, the unevenness is formed in the second region R2, and the surface in the first region R1 is made smoother than the surface in the second region R2. By the way, the rotation / non-rotation of the can 20 is also influenced by, for example, the material constituting the top coat layer 52. For this reason, for example, even when unevenness is formed in the first region R1 and the second region R2 is formed smoothly, the can 20 may be rotated / non-rotated. That is, in the present embodiment, the portion where the identification mark 23 is provided is smoothed and the unevenness is given to the portion where the identification mark 23 is not provided. For example, the metal surface and film surface of a metal bottle can or an adhesive If the at least two regions having different friction coefficients are formed corresponding to the identification mark 23 as in the combination of the nature paint and the ordinary paint, the can 20 can be rotated / non-rotated.

  In the above description, the six cans 20 are transported to the packing process using the gripping unit 50, but the cans 20 can be transported to the packing process using the stopper unit 70. 16 and 17 are diagrams for explaining another example of the method for transporting the can 20.

  In this transport method, as shown in FIG. 16A, a plurality of stopper units 70 are arranged side by side in the vertical direction. In this transport method, as shown in FIGS. 16A and 16B, first, the first supply device 41 to the sixth supply device 46 (FIG. 6 cans 20 are supplied. Thereafter, in the present transport method, as shown in FIG. 17A, the uppermost stopper unit 70 on which the can body 20 is placed is transported. Specifically, the stopper unit 70 is transported to the packing process described above. Then, the can 20 on the stopper unit 70 is transferred onto the packing material 100 in the packing process. And packing is performed similarly to the above, and the container package 200 is completed. After the uppermost stopper unit 70 is transported to the packing process, as shown in FIG. 17B, the stopper unit 70 located at the lower position is raised, and a new can body is formed with respect to the raised stopper unit 70. 20 is supplied.

  In addition, although the aspect which packs the can 20 using the packing material 100 was demonstrated above, when the display apparatus demonstrated below is utilized, the identification mark 23 attached | subjected to the can 20 is orient | assigned ahead of a display apparatus. It becomes possible. For example, although the can body 20 is displayed in a convenience store or the like, if the orientation of the identification mark 23 to which the can body 20 is attached is not aligned, it becomes difficult to identify the product, or the appearance may deteriorate. There is a fear. By using the following display device, the identification mark 23 can be directed in a specific direction (front of the display device).

FIG. 18 is a top view of the display device that displays the can 20.
The display device 80 shown in the figure has a configuration substantially similar to that of the rotation mechanism 30 shown in FIG. That is, the display device 80 includes a placement portion 81 on which the can body 20 is placed, and a guide 82 that forms a movement path of the can body 20 and guides the movement of the can body 20. Here, the guide 82 is disposed along the movement path of the can 20. The guides 82 are provided on both sides of the movement path of the can body 20.

  Here, the placement portion 81 has a placement surface 81A on which the can 20 is placed. And this mounting surface 81A is inclined and arranged so that the lower side in the figure is positioned below the upper side. In other words, the placement surface 81A is arranged so as to be inclined so that the placement surface 81A and the horizontal plane in the front-rear direction form an angle θV (hereinafter, referred to as “front-rear direction tilt angle θV” in some cases). The placement surface 81 </ b> A is disposed so as to be inclined such that the right guide 82 is positioned below the left guide 82. In other words, the mounting surface 81A is inclined so that the mounting surface 81A and the horizontal plane in the left-right direction (width direction) form an angle θH (hereinafter, sometimes referred to as “left-right tilt angle θH”). Has been.

  Further, the placement portion 81 has a first roller row 811 and a second roller row 812 arranged in parallel in the width direction of the placement portion 81 on the placement surface 81A. Here, each roller row has a plurality of roll-shaped members 814. In addition, the roll-shaped member 814 included in the first roller row 811 can be rotated along the moving direction of the can body 20 and smoothly moves the can body 20 forward. On the other hand, the roll-shaped member 814 included in the second roller row 812 is fixed so as not to rotate. For this reason, the roll-shaped member 814 included in the second roller row 812 imparts resistance against movement to the can body 20 that moves the placement portion 81.

  Here, the roll-shaped member 814 included in the second roller array 812 contacts a portion of the can body 20 that is located on the side opposite to the side where the resistance applying portion 83 (details will be described later) is provided. Gives 20 drag. In this embodiment, all the roll-shaped members 814 included in the second roller row 812 are fixed so as not to rotate. However, a part of the roll-shaped members 814 is fixed, for example, every other roll-shaped member 814 is fixed. May be.

  Further, in the present embodiment, the right guide 82 is provided with a resistance applying portion 83 that applies a sliding resistance (friction resistance) to the can body 20 that contacts the right guide 82. The resistance applying portion 83 is provided along the movement path of the can body 20. The resistance applying portion 83 is configured in the same manner as the resistance applying portion 33, and has a cylindrical base material (not shown) embedded in a groove formed in the right guide 82, and is attached to the outer surface of the base material. It is comprised from the pasting member 83B made. In addition, the display device 80 according to the present embodiment includes a stop plate 85 that stops the can body 20 that has moved to the most downstream side in the moving direction of the can body 20. The stop plate 85 is preferably formed to be transparent.

Next, operation | movement of the can 20 in the display apparatus 80 is demonstrated.
FIG. 19 is a view for explaining the operation of the can body 20 in the display device 80.
As shown by reference numeral 19A in the figure, the can body 20 placed on the placement portion 81 behind the display device 80 has an inclination in the left-right direction (width direction) and an inclination in the front-rear direction with respect to the placement surface 81A. Since it is given, it moves toward the front while being guided by the resistance giving unit 83. At this time, if the first region R1 is in contact with the resistance applying portion 83, slippage between the first region R1 and the resistance applying portion 83 is suppressed (a drag is applied to the first region R1), The can body 20 moves forward while rotating counterclockwise (see reference numerals 19A and 19B).

  When the second region R2 comes into contact with the resistance applying portion 83 as indicated by reference numeral 19C, a slip occurs between the second region R2 and the resistance applying portion 83, and the rotation of the can 20 stops. Thereafter, the can 20 moves (slides) forward while being guided by the resistance applying portion 83. Accordingly, the can body 20 that has reached the front of the display device 80 is in a state in which the identification mark 23 faces the front of the display device 80.

  In the display device 80 according to the present embodiment, similarly to the rotation mechanism 30, the roll-shaped member 814 included in the second roller array 812 (see FIG. 18) is fixed so as not to rotate. For this reason, the roll-shaped member 814 included in the second roller row 812 gives resistance against movement to the moving can body 20. Thereby, excessive rotation of the can body 20 is suppressed, and the situation in which the can body 20 rotates despite the contact between the second region R2 and the resistance applying portion 83 can be suppressed.

In the above description, the case where the can body 20 is packed with the paper packing material 100 has been described as an example. However, the can body 20 can also be packed with a transparent film or the like.
20 and 21 are views showing a container package 200 in which six cans 20 are packed with a film. As shown in FIG. 20, the container package 200 in the present embodiment has a transparent film F that covers six can bodies 20 that are arranged in two rows and arranged in a grid. It is wound around the body 20. The film F can also be a shrink film that shrinks when heat is applied.

  In the container package 200 shown in FIG. 20, the three cans 20 positioned in one of the two rows are arranged so that the identification mark 23 faces the outside of the film F and in one direction. Further, the three can bodies 20 located in the other of the two rows are arranged so that the identification mark 23 faces the outside of the film F and the direction opposite to the one direction. Here, in this embodiment, since the packaging material 100 is formed of the transparent film F, the arrangement of the can bodies 20 as described above (the arrangement where the identification marks 23 of the three can bodies 20 face the same direction). The identification mark 23 of the can 20 can be visually recognized from the outside of the packaging material 100 even if the process is performed.

  Here, the arrangement of the can body 20 as described above is such that the first supply device 41 and the fifth supply device 45 are adjacent to the sixth supply device 46 (see FIG. 2), and the second supply device 42 is connected to the third supply device 43. And it can carry out by making the 4th supply apparatus 44 adjoin. The can body 20 can also be arranged as shown in FIG. In the container package 200 shown in FIG. 21, the identification mark 23 of the can body 20 located at the corner of the six can bodies 20 arranged in a lattice pattern is directed outward and obliquely to the film F. More specifically, the direction in which the identification mark 23 of the can body 20 located in the center part (the part other than the corner part) of the six can bodies 20 faces and the direction in which the identification mark 23 of the container 20 located in the corner part faces. The can body 20 positioned at the corner is arranged so that the angle is about 45 °. Note that the can body 20 is arranged in such a manner that the first supply device 41 is arranged such that the angle formed between the sixth supply device 46 (see FIG. 2) and the first supply device 41 is 45 °. The fifth supply device 45 is arranged so that the angle formed by the supply device 46 and the fifth supply device 45 is 45 °, and the angle formed by the third supply device 43 and the second supply device 42 is 45 °. This can be done by arranging the second supply device 42 and arranging the fourth supply device 44 so that the angle formed by the third supply device 43 and the fourth supply device 44 is 45 °.

In the above description, the first protrusion 301 to the twelfth protrusion 312 (FIG. 5) are brought into contact with the largest diameter portion of the can body 20 to stop the can body 20, but the first protrusion 301 to the twelfth protrusion 312 are stopped. And the contact with the can 20 can also be performed as follows.
FIG. 22 is a view showing the first protrusion 301 and the can body 20. The second protrusion 302 to the twelfth protrusion 312 are configured in the same manner as the first protrusion 301. The first protrusion 301 in this figure has a smaller dimension in the height direction than the first protrusion 301 shown in FIG. In the present embodiment, the first protrusion 301 having a small dimension in the height direction is brought into contact with the reduced diameter portion 20A formed at the lower portion of the can body 20, as shown in FIG. In the case of the configuration shown in this figure, the gap formed between the adjacent can bodies 20 can be made smaller in the stopper unit 70.
