-First embodiment-
DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a view showing a container according to an embodiment of the present invention. 1A shows a front view, FIG. 1B shows a rear view, and FIG. 1C shows a top view.

The container 20 shown in this figure is a so-called three-piece can, and is composed of three members, a trunk portion 21, a lid member 22, and a bottom member 25, as shown in FIG.
The trunk | drum 21 as an example of a cylindrical member is formed in a cylindrical shape, and has an opening in one end located above and the other end located below. The body portion 21 is tapered, and the body portion 21 is formed such that the diameter (outer diameter) gradually increases toward the bottom. Here, the body portion 21 is formed by performing a welding process after a plate-like base material (blank material) is formed into a cylinder. For this reason, the trunk | drum 21 has the welding part 24 along the height direction of the container 20, as shown to the same figure (B).

  The lid member 22 as an example of the closing member is configured as a separate member from the trunk portion 21. The lid member 22 is formed in a disc shape and is fixed to the upper edge portion of the body portion 21 formed in a cylindrical shape by so-called winding. Thereby, the opening formed in the one end side of the trunk | drum 21 is closed. The bottom member 25 is also formed in a disc shape and is fixed to the lower edge portion of the body portion 21 formed in a cylindrical shape by so-called winding. Thereby, the opening formed in the other end side of the trunk | drum 21 is closed.

  Here, as shown in FIG. 5C, the lid member 22 is operated by the user when the drinking mouth is formed and presses the planned opening area 44 described later to form the opening. An opening tab 42 that forms an opening in the planned area 44 is provided. Here, the opening tab 42 is arranged so as to have a predetermined positional relationship with the planned opening area 44. In addition, the base 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). The base 41 is formed with a score (scheduled fracture line) 41 a surrounding the planned opening area 44.

  The opening tab 42 is attached to one surface of the base 41. Further, the opening tab 42 is provided along the one surface of the base 41, and the ring hole 42c penetrates from the facing surface facing the base 41 toward the surface opposite to the facing surface. have. Further, the opening tab 42 is provided from the center of the base 41 to the base 41 toward the outer peripheral edge. The opening tab 42 is a rigid plate-like member, and is fixed to the base 41 by a rivet 43 provided at the center of the base 41. That is, the opening tab 42 includes a fixing portion 42 a that is fixed to the base portion 41 via the rivet 43. Further, the opening tab 42 includes a ring portion 42b extending along the base portion 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 portion 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 location where the rivet 43 is provided, and the planned opening area 44 is the other side of the container 20 with respect to the location 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.

  Moreover, in the container 20 in this embodiment, the design including a character, a figure, etc. is printed on the outer peripheral surface of the trunk | drum 21. FIG. The symbol includes a first identification mark 23a and a second identification mark 23b for distinguishing from other products such as a product name and a trade name (in the present specification, hereinafter, simply referred to as "identification mark 23"). "). Here, as shown in FIG. 1C, the first identification mark 23a and the second identification mark 23b are arranged with a phase shifted by 180 ° in the circumferential direction of the container 20. It should be noted that the first identification mark 23a and the second identification mark 23b can 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. In addition, in this embodiment, the lid member 22 is fixed to the trunk portion 21 after the position of the lid member 22 is controlled so that the identification mark 23 and the planned opening area 44 have a predetermined positional relationship. Is done. More specifically, in the present embodiment, when the lid member 22 is attached to the trunk portion 21, for example, the identification mark 23 (which may be a welded portion 24 or the like) of the trunk portion 21 is detected, Grasp the posture (rotation angle). Thereafter, the lid member 22 is rotated in the circumferential direction by an angle corresponding to the posture (rotation angle) of the body portion 21. As a result, the identification mark 23 and the scheduled opening area 44 have a predetermined positional relationship. Thereafter, the lid member 22 is fixed to the body portion 21.

  Note that the above rotation of the lid member 22 according to the posture of the trunk portion 21 (control of the position of the lid member 22) is, for example, a circle as shown in FIG. 17 (a diagram for explaining the rotation of the lid member 22). This can be done by pressing the opening tab 42 from the side with the moving pin PN. In the embodiment shown in FIG. 17, the lid member 22 is conveyed by the conveyance belt 810 in a state where the lid member 22 is accommodated in the recess 820 formed in the conveyance belt 810. In this embodiment, the pin PN moves while accompanying the lid member 22, and the lid member 22 is rotated by the pin PN.

  Further, for example, as shown in FIG. 18 (a diagram for explaining the rotation of the lid member 22), the lid member 22 is rotated on the moving path of the unsealing tab 42 while rotating the lid member 22 in the circumferential direction. This can be done by projecting the PN and restricting the movement of the opening tab 42 using the pin PN. More specifically, in the embodiment shown in FIG. 18, when the lid member 22 located in the recess 820 reaches the position opposite to the drag application member 865, the conveyor belt 810 is inclined, and thus the drag application member. It slides toward 865 and contacts the drag application member 865 as indicated by reference numeral 8A. Thereby, the cover member 22 comes to rotate counterclockwise (circumferential direction). On the other hand, the solenoid S is turned off. As a result, the pin PN of the rotating member 864A moves toward the conveyor belt 810 as indicated by reference numeral 8A in FIG. Next, the motor M is driven and the pin PN is lowered. As a result, the pin PN is positioned at a predetermined position on the moving path of the opening tab 42. Thereafter, as shown by reference numeral 8B in FIG. 18, the opening tab 42 contacts the pin PN, and the rotation of the lid member 22 is stopped. Here, the rotating member 864A, the pin PN, the motor M, the solenoid S, and the like are attached to a belt member 860 that circulates. In the above description, the lid member 22 is rotated in the circumferential direction, but the body portion 21 can also be rotated in the circumferential direction. Moreover, both the trunk | drum 21 and the cover member 22 can also be rotated in the circumferential direction.

The positional relationship between the identification mark 23 and the planned opening area 44 will be further described. In the present embodiment, the identification mark 23 and the planned opening area 44 are arranged with a phase shifted by 90 ° in the circumferential direction of the container 20. ing.
Further description will be made with reference to FIG. 1C. When the first identification mark 23a is oriented in one direction (right direction in the figure), the planned opening region 44 is in a direction perpendicular to the one direction (lower in the figure). The planned opening region 44 and the first identification mark 23a are arranged so as to be arranged along the direction). Further, when the second identification mark 23b faces one direction (left direction in the figure), the planned opening area 44 is arranged along a direction (downward direction in the figure) perpendicular to the one direction. The planned opening area 44 and the second identification mark 23b are arranged.

  More specifically, when the axis center of the container 20 is used as a reference, the planned opening region 44 is arranged along one direction from the axis center toward the trunk portion 21. 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 body portion 21, and the first identification mark 23 a and the second identification mark 23 b 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 23a and the second identification mark 23b are arranged so that the first identification mark 23a and the second identification mark 23b face the direction perpendicular to the virtual line when assuming a virtual line passing through the center of the lid member 22 and the planned opening area 44. The outer peripheral surface of the portion 21 is attached.

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 generally carried out 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 sideward 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 recognizable by a third party, it is possible to produce an advertising effect.

  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. Further, when it is desired to show the identification mark 23 to the person who drinks the drink, the identification mark 23 can be attached to both the planned opening area 44 side and the opposite side.

  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 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 for explaining a manufacturing process of the container 20.
In the manufacturing process of the container 20 in the present embodiment, first, coating is performed on one surface (the surface that becomes the inner surface of the container 20) of a plate-like base material (plate-like member) such as a steel plate or a tin plate (not shown). I do. In addition, it can replace with coating and can also affix a resin film, for example. Subsequently, this base material is heated, and the coating applied to the one surface is baked. After that, for example, by multi-color offset printing, the design including the identification mark 23 is printed on the other surface of the base material (the surface to be the outer surface of the container 20). Next, the substrate is heated again, and the printed pattern is baked. Thereafter, the base material on which the pattern has been baked is subjected to shearing (cutting). As a result, as shown in FIG. 3A, a base material (blank material) having a pattern including the first identification mark 23a and the second identification mark 23b and having a substantially trapezoidal shape is formed.

  Then, a welding process is performed with respect to the said base material rounded in the forming process (cylinder formation process) not shown and the both sides were overlapped. Further, one opening side and the other opening side of the cylindrical body completed by the welding process are pressed against the mold to perform flange processing. Thereby, the trunk | drum 21 demonstrated above is completed (refer FIG. 3 (B)). Thereafter, the lid member 22 manufactured in a separate process and having the opening tab 42 and the planned opening region 44 is wound around the upper edge of the body portion 21 as shown in FIG. Fixed to tighten. At this time, as described above, the lid member 22 is fixed to the trunk portion 21 after the position of the lid member 22 is controlled. Thereby, as described above, the identification mark 23 attached to the body portion 21 and the planned opening area 44 formed in the lid member 22 have a predetermined positional relationship.

  Then, the upper and lower sides of the trunk portion 21 are reversed so that the lid member 22 is positioned below, and the beverage is filled from the opening located at the upper portion of the trunk portion 21 (see FIG. 4D). Thereafter, as shown in FIG. 5E, the bottom member 25 is placed on the trunk portion 21, and then the bottom member 25 is fixed to the trunk portion 21 by so-called winding. Thereby, the container 20 shown in FIG. 1 is completed. The steps (A) to (C) are generally performed by a container manufacturer. And after completion of a process (C), the trunk | drum 21 to which the cover member 22 was attached is conveyed (conveyed) to a drink maker, and the said process (D) and (E) are implemented in a drink maker. In the present specification, hereinafter, the body portion 21 to which the lid member 22 is attached may be referred to as a base body 29.

  Here, FIG. 4 is a diagram showing a state of the trunk portion 21 during transportation. In the present embodiment, as described above, the body portion 21 is tapered, and the diameter of the body portion 21 gradually increases toward the lower side (side on which the opening is formed). More specifically, in the present embodiment, the diameter of the other end of the trunk portion 21 (the diameter of the lid member 22) is smaller than the diameter of the opening formed on the one end side of the trunk portion 21. For this reason, the one trunk | drum 21 in this embodiment can enter the inside of the other trunk | drum 21 located below this one trunk | drum 21 as shown in FIG. As a result, when the trunk | drum 21 in this embodiment is employ | adopted, it becomes possible to improve the transport efficiency at the time of transport. In addition, when the body portion 21 in the present embodiment is employed, a larger number can be carried than the body portion 21 having a diameter that is substantially equal in the height direction. In addition, as shown to the same figure, the protective cap HC which covers the cover member 22 fixed with respect to the trunk | drum 21 located in the lowest part among the some laminated | stacked trunk | drums 21 can also be attached.

  In addition, when the manufacturing method in this embodiment is employ | adopted, the container 20 in which a gravity center position is located in the lower part side of the container 20 can be manufactured. In addition, when the container 20 is placed in a normal state (when the container 20 is placed in a state where the planned opening region 44 is located at the upper part of the container 20), the container 20 whose center of gravity is located on the lower side is disposed. Manufacturable. And such a container 20 becomes difficult to fall compared with the case where a gravity center position is located in the upper part of the container 20. FIG.

  Here, the process performed on the beverage manufacturer side will be described in detail. In the beverage maker, first, the base 29 (the body portion 21 to which the lid member 22 is fixed) that has been transported in a stacked state is subjected to a process of separating the bases 29. This process is performed by, for example, the apparatus shown in FIG. This apparatus is provided with a transport device 600 that is located above the substrate 29 and conveys the substrate 29 while sucking it, and a stopper 610 that is located on the side of the substrate 29 and suppresses the movement of the substrate 29 located below the substrate 29 to be sucked. I have. The stopper 610 is composed of two movable pieces 611 provided so as to be movable toward and away from the base 29, and contacts the end of the base 29 to suppress the movement of the base 29. It is also possible to provide a pressing piece 620 that is provided so as to be movable in the direction approaching and leaving the base 29 and presses the side portion of the base 29.

  In addition, in the beverage manufacturer, an attachment member that functions as a cap can be attached to each of the base bodies 29. More specifically, as shown in FIG. 13 (a diagram showing the mounting process of the mounting member), the mounting member 630 can be mounted on the side of the base 29 on which the drinking mouth is formed. When the mounting member 630 is mounted in this way, contamination around the drinking mouth of the base 29 is prevented. Note that the mounting member 630 can be mounted by, for example, the mounting device 640 shown in FIG. The mounting device 640 includes, for example, a first conveyor 641 that conveys the substrate 29, a conveyance device 642 that lifts and conveys the substrate 29 conveyed by the first conveyor 641, and a substrate 29 that is lifted by the conveyance device 642. The mounting device 643 for mounting the mounting member 630 and the second conveyor 644 for transporting the base 29 on which the mounting member 630 has been mounted can be configured.

  The mounting member 630 is removed by the removing device 650 as shown in FIG. 14 (showing the mounting member removing process) after filling the base 29 with the beverage and attaching the bottom member 25 to each other. . As shown in the figure, the detaching device 650 includes an inverting device 651 for inverting the container 20 (base 29) upside down, and a detaching device 652 for removing the mounting member 630 from the container 20 inverted by the inverting device 651. Yes. Here, the removal device 652 is mounted using a first suction unit 652A that is disposed inside the transport belt 654 and sucks the container 20 from the inside of the transport belt 654, and a second suction unit 652B that sucks the mounting member 630. The member 630 is removed. The mounting member 630 removed by the removing device 652 is transported to the mounting device 640 (see FIG. 13) by a transport device (not shown). Then, it is mounted on a new base 29 by the mounting device 640.

  The container 20 filled with a beverage and attached with the bottom member 25 is a packing material such as a paper pack or a transparent film, as shown in (A) and (B) of FIG. 15 (a diagram showing a container package). It is packed from 710 and shipped in a package 700. 15A is a front view of the package 700, and FIG. 15B is a cross-sectional view of the package 700 as viewed from above. Here, as shown in FIG. 15B, the container 20 can be inverted every other (every other can). In this case, the volume of the package 700 can be reduced as compared with the case where the top and bottom are not reversed. Moreover, the container 20 can also be arrange | positioned so that the identification mark 23 may face the outer side of the packaging material 710, as shown to FIG. 15 (A). In this case, an advertising effect is produced. In order to make the identification mark 23 face the outside of the packaging material 710, it is necessary to rotate the container 20 in the circumferential direction to align the direction of the identification mark 23. This alignment is different in the friction coefficient of the container 20. A plurality of regions can be formed (described later), and a function similar to the function provided to the display device 30 described later can be provided in the transport path of the container 20.

  When the container 20 (body portion 21) is tapered, a dead space is likely to be generated inside the packing material 710. And if a dead space arises in this way, it will become easy to shake the container 20 during conveyance. For this reason, as shown in FIGS. 15A and 15B, it is desirable to form a folded portion 760 in which the packing material 710 is folded. In addition, although the aspect which reversed the top and bottom of the container 20 every 6 can packs and every other was demonstrated above, as shown to (A) of FIG. 16 (the figure which showed the packaging body of the container), 7 cans are shown. You may put it all together. Here, in FIG. 16A, one container 20 is arranged at the center, and six containers 20 are arranged around the container 20. In FIG. 16A, the top and bottom of the container 20 located at the center is reversed. Further, as shown in FIG. 16B, the top and bottom of the two containers 20 that are located far from the center and are in the most distant relationship can be reversed. In FIG. 16, the packaging material 710 is not shown.

-Second Embodiment-
FIG. 5 is a view showing the container 20 in the second embodiment. In addition, also in this figure, what is called a 3 piece can is illustrated. Here, FIG. 1A shows a front view, FIG. 1B shows a rear view, and FIG. 1C shows a top view. The same functions as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted here.

  In the first embodiment, the container 20 in which the lower diameter is larger than the upper diameter has been described. However, as shown in FIG. 5, the lower diameter may be smaller than the upper diameter. it can. More specifically, in the present embodiment, the taper applied to the body portion 21 of the container 20 is different from that in the first embodiment. Specifically, the body portion 21 of the container 20 in the present embodiment is tapered such that the diameter gradually increases toward the top.

  In the present embodiment, similarly to the first embodiment, a lid member 22 that closes one opening of the body portion 21 and a bottom member 25 that closes the other opening are provided. Here, in the present embodiment, since the opening located above the trunk portion 21 is larger than the opening located below, unlike the first embodiment, the diameter of the lid member 22 is the bottom member. The diameter is larger than 25. Note that the scheduled opening area 44 and the identification mark 23 in the present embodiment are also arranged with a predetermined positional relationship, as in the first embodiment. In addition, the planned opening area 44 and the identification mark 23 are arranged so that the identification mark 23 is arranged at a position where a third person can recognize when a beverage is drunk.

  Here, the manufacturing method of the container 20 in 2nd Embodiment is demonstrated. In the manufacturing process of the container 20 in the present embodiment, the processing shown in FIGS. 3A and 3B is first performed, and the body portion 21 is formed as in the first embodiment.

That is, the placement unit 31 is disposed in a state of being inclined downward from the rear side of the display case 10 toward the front side (extraction unit side) from which the container 20 is taken out.

  Here, the display case 10 in the present embodiment is provided with a door on the rear side (not shown), and the rear side can also be opened. And the container 20 is thrown into the display apparatus 30 from this back side. In other words, the container 20 is provided on the rear side of the display case 10 and the rear side of the display device 30. And the thrown container 20 moves on the mounting part 31 toward the door 10B side. In this specification, the door 10B side may be referred to as the front side (front), and the side opposite to the door 10B may be referred to as the rear side (rear). In addition, the width direction of the display case 10 (the direction orthogonal to the direction in which the container 20 moves) may be referred to as a horizontal direction or a width direction.

The display device 30 will be further described.
FIG. 8 is a top view of the display device 30.
The guide 32 of the display device 30 in the present embodiment is disposed along the movement path of the container 20. The guides 32 are provided on both sides of the movement path of the container 20. Here, the guide 32 is formed of a metal material such as aluminum or a resin material, for example.

  The placement unit 31 is disposed to be inclined in the width direction. More specifically, one guide 32 (left guide 32 in the figure) side is inclined and disposed so as to be positioned below the other guide 32 (right guide 32 in the figure) side. . Moreover, the mounting part 31 is inclined and disposed so that the front side is positioned below the rear side as described above. Here, reference numerals 2 </ b> A and 2 </ b> B in FIG. In the present specification, hereinafter, the left guide 32 may be referred to as a left side guide 32 and the right guide 32 may be referred to as a right side guide 32.

  Further, the placement unit 31 includes a first roller group 311, a second roller group 312, and a third roller group 313 arranged in parallel in the width direction of the placement unit 31 on the surface on which the container 20 is placed. . Here, each roller group has a plurality of roll-shaped members 314 that can rotate along the moving direction of the container 20 and are arranged in the front-rear direction.

Moreover, the resistance provision part 33 can be comprised also with the vinyl tape comprised by the vinyl chloride etc. which are affixed on the rod-shaped member with a circular cross section, for example. The resistance applying portion 33 can also be configured by a rubber member such as EPDM (ethylene-propylene rubber). Further, the resistance applying portion 33 can be formed of a resin material.

Next, the container 20 will be described.
FIG. 9 is a view for explaining the surface state of the container 20.
9A shows the container 20 from one side, and FIG. 9B shows the container 20 from the other side. 3C shows a cross section at the S portion in FIG. 1A, and FIG. 1D shows a cross section at the T portion in FIG. In FIG. 9, illustration of the planned opening area 44 and the opening tab 42 provided on the lid member 22 (see FIG. 1) is omitted. In FIG. 9B, the welded portion 24 (see FIG. 1B) is not shown.

  In the container 20 according to the present embodiment, as shown in FIG. 9, as described above, a design including characters and figures is printed on the outer peripheral surface of the trunk portion 21. The design includes a first identification mark 23a and a second identification mark 23b for identifying the product name, trade name, and other products. Here, the first identification mark 23 a and the second identification mark 23 b are arranged with a phase shifted by 180 ° in the circumferential direction of the container 20.

  Moreover, the container 20 has 1st area | region R1-4th area | region R4 in the outer peripheral surface of the trunk | drum 21, as shown to the same figure (A) and (B). Here, these regions are provided in the order of the first region R1, the second region R2, the third region R3, and the fourth region R4 in the circumferential direction of the container 20. In addition, the surface state of 1st area | region R1 and the surface state of 3rd area | region R3 are comprised similarly. Moreover, the surface state of 2nd area | region R2 and the surface state of 4th area | region R4 are comprised similarly. For this reason, in the following description, it demonstrates focusing on 1st area | region R1 and 2nd area | region R2. Furthermore, in the present embodiment, the friction coefficient on the surface satisfies the first region R1 (third region R3)> the second region R2 (fourth region R4).

Here, the surface state of the second region R2 will be described first with reference to FIG.
As shown in FIG. 5C, in the second region R2, an ink layer 51 is provided on the surface of a base material 50 such as a steel plate or a tin plate constituting the body portion 21. In addition, a top coat layer (outermost layer) 52 having crater-like irregularities is provided on the surface of the ink layer 51.

  Here, as the ink used for the ink layer 51, for example, one for metal printing can be used. Here, as the pigment (color amount) of the ink, various organic pigments and inorganic pigments are used. The ink vehicle is mainly composed of a resin such as a thermosetting resin or an ultraviolet curable resin. Here, as the thermosetting resin, an alkyd type or polyester type resin or the like is used. As the ultraviolet curable resin, an ultraviolet radical polymerization type resin, an ultraviolet cation polymerization type resin, or the like is used. Furthermore, the ink may contain an additive. Additives include matting agents, waxes (natural, petroleum, synthetic), desiccants, dispersants, wetting agents, crosslinking agents, gelling agents, thickeners, anti-skinning agents, stabilizers, An antifoaming agent, a photopolymerization initiator, or the like is used.

  The ink layer 51 is formed of a so-called repelling ink. That is, the ink layer 51 is formed of ink that repels the paint when the paint for forming the topcoat layer 52 is applied to the surface of the ink layer 51. Here, the unevenness in the top coat layer 52 is formed by repelling the paint forming the top coat layer 52 by the ink layer 51.

  In order to repel the paint for forming the top coat layer 52 by the ink layer 51 (to form the unevenness), the surface tension of the ink used for forming the ink layer 51 is used for forming the top coat layer 52. It is desirable to set 5 mN / m or more lower than the surface tension of the paint. In other words, it is desirable that the surface tension of the ink is lower than the surface tension of the paint, and that the difference in surface tension between the ink and the paint is 5 mN / m or more. Here, the reduction of the surface tension of the ink can be carried out, for example, by adding silicone to normal ink.

On the other hand, the coating material used for the topcoat layer 52 is mainly composed of a resin such as a thermosetting resin or an ultraviolet curable resin, and contains a wax component as necessary.
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.

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, the ink layer 51 is provided on the surface of the substrate 50 as described above. A topcoat layer (outermost layer) 52 having a surface smoother than the topcoat layer 52 in the second region R2 is provided on the surface of the ink layer 51.

  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.

  The first identification mark 23a is formed in the first region R1, and the second identification mark 23b is formed in the third region R3. The first identification mark 23 a and the second identification mark 23 b are formed by the ink layer 51.

Next, the operation of the container 20 in the display device 30 will be described.
FIG. 10 is a view for explaining the operation of the container 20 in the display device 30. In the drawing, the first roller group 311, the second roller group 312, and the third roller group 313 (see FIG. 8) are not shown.
When the container 20 is placed behind the placement portion 31 (see reference numeral 4A), the container 20 moves forward while being guided by the left side guide 32. 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 container 20 moves forward while rotating clockwise (see reference numeral 4B).

  And if 2nd area | region R2 will be in the state which contacts resistance provision part 33 like code | symbol 4C, a slip will arise between 2nd area | region R2 and resistance provision part 33, and rotation of the container 20 will stop. Thereafter, the container 20 moves (slides) forward while being guided by the left side guide 32. Thereby, the container 20 that has reached the front of the display device 30 is in a state in which the second identification mark 23b faces forward. In addition, in the present embodiment, the second region R2 and the second identification mark 23b are arranged with a predetermined positional relationship determined in advance. More specifically, when the second region R2 is directed leftward (one direction), the second identification mark 23b is disposed so as to face forward (a direction intersecting one direction, a direction orthogonal to the one direction). Has been. For this reason, when the second region R2 comes into contact with the resistance applying portion 33, the second identification mark 23b faces forward.

  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. After the identification mark 23 faces forward, it is preferable that the sliding resistance applied from the left side guide 32 to the container 20 is as small as possible. For this reason, in FIG. 8B, the resistance applying portion 33 is arranged halfway along the movement path of the container 20, and the resistance applying portion 33 is not provided from a predetermined position to the take-out portion of the container 20.

  In the present embodiment, the mounting portion 31 is inclined in the width direction. However, for example, the front portion of the resistance applying portion 33 may not be inclined in the width direction. Also in this case, the sliding resistance acting on the container 20 from the left side guide 32 is lowered, and the container 20 is difficult to rotate. Further, in the above, the container 20 is brought into contact with the resistance applying part 33 by giving the inclination in the width direction to the mounting part 31, but the container 20 is brought into contact with the resistance applying part 33 without giving the inclination in the width direction. Can do. For example, an urging member such as a leaf spring is provided on the right side guide 32 side, and the container 20 can be brought into contact with the resistance applying portion 33 using this urging member.

Here, a method of forming the first region R1 to the fourth region R4 will be described in more detail.
In the manufacturing process of the container 20 in the present embodiment, as described above, the design including the identification mark 23 is printed on one surface of the base material (the surface that becomes the outer surface of the container 20) by multicolor offset printing. . Here, the first region R1 to the fourth region R4 can be formed when this multicolor offset printing is performed.

FIG. 11 is a diagram illustrating an example of a printing machine that performs multicolor offset printing.
A printing machine 500 shown in the figure has a printing plate corresponding to a design, and applies an ink for forming the ink layer 51 on a base material. The ink coating device 520 is disposed opposite to the ink coating device 520 and passes through a transfer portion Te. A support roll 550 for supporting the base material to be coated, a paint application roll 560 for applying the paint for forming the top coat layer 52, and a support roll 561 for supporting the base material disposed at a position opposite to the paint application roll 560.

  The ink application device 520 includes a printing cylinder 522 that contacts the base material, 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 a printing plate on its outer peripheral surface, and transfers the ink supplied by the ink supply device 521 to the substrate. In addition, although illustration is abbreviate | omitted in this figure, the ink application apparatus 520 is provided with two or more for every color along the conveyance path | route of a base material. In the printing press 500, different color inks are sequentially placed from the plurality of ink applicators 520 provided on the surface of the substrate. Thereby, an ink image corresponding to the design is formed on the surface of the substrate. Thereafter, in the printing machine 500, the paint is applied to the surface of the base material (the base material on which the ink layer 51 is formed) onto which the ink image has been transferred by the paint application roll 560. 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, the second region R2 and A surface difference can be formed between the first region R1 and the third region R3 adjacent to the second region R2. In the above description, the coating material is supplied from the coating material application roll 560 to the base material. However, the coating material can also be supplied from the ink application device 520 located on the most downstream side in the transport direction of the base material. In addition, although the description is omitted above, the ink can be appropriately dried between the adjacent ink coating apparatuses 520.

  In the above, so-called repellant ink is used to form irregularities in the second region R2, but for example, so-called foamed ink containing a foaming agent is used to form the ink layer 51 and irregularities are formed in the second region R2. Also good. 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 left side guide 32 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 to the fourth region R4 is formed with a mat paint, a paint that smoothes the surface of the first region R1 and the third region R3 (for example, the glass or the like) May also be applied. That is, by applying a mat paint, the entire circumference of the container 20 is made slippery, and then a paint for smoothing the surface is applied to the first region R1 and the third region R3, and the first region R1 and the third region R3 are applied. It may be difficult to slip. Further, for example, after the topcoat layer 52 in the first region R1 to the fourth region R4 is formed with a mat paint, the above-mentioned Teflon (registered trademark) tape or seal having a smaller friction coefficient than the topcoat layer 52, for example. Etc. may be attached to the second region R2 and the fourth region R4.

  Furthermore, in the above, the unevenness is formed in the second region R2 and the fourth region R4, and the surfaces in the first region R1 and the third region R3 are made smoother than the surfaces in the second region R2 and the fourth region R4. The identification mark 23 was directed forward. By the way, the rotation / non-rotation of the container 20 is also influenced by, for example, the material constituting the top coat layer 52. For this reason, even when the first region R1 and the third region R3 are uneven and the second region R2 and the fourth region R4 are formed smoothly, the identification mark 23 can be directed forward. There is. 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. However, the present invention is not limited to such a form, and at least 2 having a different friction coefficient. If one region is formed corresponding to the identification mark 23, the identification mark 23 can be directed forward.
