=== Coupled body 102 of the cup container according to the present embodiment ===
4 to 5C are explanatory views of the coupling body 102 of the cup container according to the present embodiment. FIG. 4 is an exploded perspective view of the coupling body 102 of the cup container. 5A is a plan view of the coupling body 102 of the cup container as viewed from the front surface side, FIG. 5B is the same plan view as viewed from the back surface side, and FIG. 5C is a side view thereof.

  As shown in FIG. 4, the coupling body 102 of the cup container according to the present embodiment is configured to block a plurality of cup containers 101 for storing commodities such as food and all the mouth portions 101 a of the plurality of cup containers 101. A closing sheet 103 and a reinforcing sheet 105 for reinforcing the closing sheet 103 are provided. Hereinafter, each component will be described.

<Cup container 101>
The cup container 101 has a tapered cylindrical paper tube having a predetermined thickness as a body portion 101b. Specifically, the outer diameter of the cup container 101 decreases from the upper end toward the lower end. As the material of the paper tube, for example, silica (SiO ₂ ) vapor-deposited paper (hereinafter also referred to as silica vapor-deposited paper) or polyethylene-coated paper (hereinafter also referred to as polyethylene-coated paper) is used in order to provide airtightness. Then, the body 101b is formed by being wound into a tapered cylindrical shape with the silica vapor deposition surface or the polyethylene coating surface directed toward the inner peripheral side.

  An airtight circular bottom 101c made of silica-deposited paper, polyethylene coated paper, or the like is fixed to the lower end of the body 101b, whereby the lower end of the body 101b is closed in an airtight state.

  On the other hand, there is a mouth portion 101a of the cup container 101 at the upper end of the body portion 101b, and the mouth portion 101a extends horizontally outward in the radial direction over the entire circumference, that is, in an annular shape. It has a flange 101a. As shown in FIG. 5B, a closing sheet 103 described later is attached to the upper surface of the flange 101a serving as the mouth, and the mouth 101a of the cup container 101 is closed in an airtight state. The flange 101a is also made of the above-described silica-deposited paper, polyethylene-coated paper, or the like.

<Occlusion sheet 103>
As shown in FIGS. 5B and 5C, the closing sheet 103 is a lid that closes the mouth portions 101a of the plurality of cup containers 101 over all the mouth portions 101a, and at the same time holds the plurality of cup containers 101. It is also a connecting member that is connected and integrated, and the back surface of the closing sheet 103 is attached to the mouth portion 101a. In this example, as shown in FIG. 4, four cup containers 101 are arranged one by one on the front, rear, left and right sides with a predetermined interval between the mouth parts 101 a of adjacent cup containers 101. All the mouth portions 101a are attached to the back surface of one closing sheet 103 and closed. As a result, as shown in FIGS. 5B and 5C, the four cup containers 101 are connected and integrated to form a so-called quadruple pack cup container connection body 102.

  This closing sheet 103 is an existing sheet that is widely used when sealing the mouth of the cup container. For example, a paper having silica vapor deposition or polyethylene coating applied to the back surface thereof, like the cup container 101. It is an airtight sheet.

  In addition, the external shape is determined according to the arrangement state of the four cup containers 101 constituting the coupling body 102 of the cup container. Here, as shown in FIG. 5B, four cup containers 101 are arranged one by one in the front, rear, left, and right, so the outer contour of the closing sheet 103 as the lid portion of the coupling body 102 of the cup container is As shown to 5A, it has a substantially square shape. Then, with the hot melt adhesive applied over the entire back surface of the closing sheet 103, the back surface of the closing sheet 103 is attached to the flange 101a which is the mouth of each cup container 101 as shown in FIG. 5B. Attached.

<Reinforcing sheet 105>
As shown in FIG. 5B, the reinforcing sheet 105 is for selectively reinforcing a low-rigidity portion of the closing sheet 103 that is easily deformed in the state of the coupling body 102 of the cup container. This low-rigidity portion is a portion that does not close the mouth portion 101a in the closing sheet 103, and is thus a region that does not close the mouth portion 101a on the back surface of the closing sheet 103. The reinforcing sheet 105 is selectively attached only to the above. This pasting is performed with a hot melt adhesive or the like applied to the back surface of the closing sheet 103.

  Here, in the present embodiment, only one reinforcing sheet 105 is attached to the back surface of the closing sheet 103 as shown in FIG. 4, and the single reinforcing sheet 105 is used as shown in FIG. 5B. The sheet 105 covers the entire periphery of each of the mouth portions 101a in the region where the mouth portion 101a is not closed over the entire circumference. In other words, the single reinforcing sheet 105 is a substantially square sheet having a similar outer shape and slightly smaller than that of the closing sheet 103, and the reinforcing sheet 105 includes four cup containers 101. A hole 105a having a diameter slightly larger than that of the mouth portion 101a is formed so as to correspond to all the mouth portions 101a. When the hole 105a is attached to the closing sheet 103, the reinforcing sheet 105 has A corresponding mouth portion 101a of the cup container 101 is located inside each of the holes 105a.

  Therefore, for the portion of the back surface of the closing sheet 103 that does not close the mouth portion 101a (see the hatched portion in FIG. 3), which is a low rigidity portion to be reinforced in the closing sheet 103, As shown in FIG. 5B, the entire portion is reinforced, and as a result, the deformation of the coupling body 102 of the cup container is further suppressed.

  Incidentally, in this embodiment, a portion other than the portion of the closing sheet 103 that does not close the mouth portion 101a, that is, a circular portion that closes the mouth portion 101a of the closing sheet 103 (FIG. 3). This is because the rigidity of the circular portion is enhanced by the mouth portion 101a of the cup container 101, and there is no need for reinforcement.

  In the present embodiment, since the closing sheet 103 is reinforced on the back surface thereof, the closing sheet 103 is not obstructed at all without impairing the notation of the product name, design, etc. applied to the surface of the closing sheet 103. The sheet 103 also has an effect of being reinforced.

As a material for such a reinforcing sheet 105, it is desirable to use a paper sheet in consideration of recyclability, and it is more preferable to use a thick paper having a basis weight of 190 to 450 g / m ² . For example, NEW ULTRA-H (trade name), REFINE (trade name), JET-ACE-W (trade name), JET STAR (trade name), which is a coated cardboard made by Nippon Daishowa Paperboard Co., Ltd. ) Etc. are applicable. Needless to say, the basis weight of the cardboard in the above range is appropriately selected depending on the weight of the contents.

  Desirably, as shown in FIGS. 4, 5A, and 5B, the closing sheet 103 and the reinforcing sheet 105 are provided in the portion between the cup containers 101 and 101 in the closing sheet 103 and the reinforcing sheet 105. It is preferable to form perforations 103b and 105b for dividing the sheet 105 into cup containers 101. In the illustrated example, perforations 103b and 105b are formed in a cross shape so as to divide the substantially square-shaped closing sheet 103 and reinforcing sheet 105 into four equal parts. If such perforations 103b and 105b are formed, the cup container connector 102 can be easily attached to each cup container 101 by the purchaser's hand while maintaining the closed state of the mouth portion 101a. The cup container 101 is easy to use.

=== The manufacturing apparatus 1 and the manufacturing method of the coupling body 102 of the cup container according to the present embodiment ===
6A and 6B are explanatory diagrams of the manufacturing apparatus 1 and the manufacturing method of the above-described cup container coupling body 102. 6A is a side view of the manufacturing apparatus 1 of the coupling body 102 of the cup container, and FIG. 6B is a BB cross-sectional view in FIG. 6A.

  The manufacturing apparatus 1 is defined at a plurality of processing positions P1, P2,... P7 set along the conveyor 11 while the cup container 101 is horizontally conveyed from the rear to the front in the traveling direction of the conveyor 11. By performing various processes, the above-described quadruple pack cup container connector 102 is manufactured.

  That is, the conveyor 11 includes, as the plurality of processing positions, a cup container loading position P1 for feeding the cup containers 101 formed in the previous process into the conveyor 11 in units of four, and the inside of the four cup containers 101. A product filling position P2 for filling a product such as food as contents, a reinforcing sheet supply position P3 for supplying one reinforcing sheet 105 to the four cup containers 101, and a closing sheet roll 103r The closing sheet supply position P4 for supplying the closing sheet continuous body 103e continuously drawn out from the mouth portion 101a of the four cup containers 101, and the assigned closing sheet continuous body 103e. Are attached to the mouth portions 101a of the four cup containers 101 to close the respective compositions 101a. The closing sheet attaching position P5 for attaching the reinforcing sheet 105 to the closing sheet continuous body 103e, and the lid 103 of the connecting body 102 of the cup container from the attached closing sheet continuous body 103e. And a carry-out position P7 for carrying out the coupling body 102 of the cup container to the next process.

  Hereinafter, the conveyor 11 and the processing positions P1, P2,... P7 will be described.

<Conveyor 11>
The conveyor 11 is a slat conveyor in which a plurality of horizontal slats (small plates) 13 are arranged on an endless chain 12. These slats 13 are intermittently driven for each processing position so as to stop for the time required for each processing.

  7 to 9C are explanatory views of the slats 13. FIG. 7 is a perspective view of the slat 13 as seen from the front. FIG. 8 is a plan view of the slat 13. 9A is a cross-sectional view taken along the line IX-IX in FIG. FIG. 9B is a cross-sectional view of the IX-IX in a state where the slat 13 supports the cup container 101. 9C is a cross-sectional view taken along the line IX-IX in a state where the slat 13 further supports the reinforcing sheet 105 in addition to the cup container 101 of FIG. 9B.

  The slat 13 shown in FIGS. 7 to 9C functions as a mounting table for supporting the cup container 101. As the material, a rectangular plate having such a rigidity that it does not bend during the series of processing is used. Further, in order to execute each process stably, the movement of the slat 13 in the vertical direction at each process position P1, P2,...

  As shown in FIGS. 7 and 8, the slat 13 has a through hole 13 a (corresponding to a fitting hole) that penetrates the slat 13 in the vertical direction that is the thickness direction, and is orthogonal to the front and rear traveling directions. A total of four are formed, two in each of the left and right width directions.

  As shown in FIG. 9B, each through-hole 13a is for fitting and supporting the cup container 101, and the tapered cup container can be inserted and removed without resistance. 101 is formed in a circular hole having a diameter slightly larger than the maximum diameter of the body 101b (here, the outer diameter of the upper end of the body 101b). In the state where the cup container 101 is fitted in the through hole 13a, the lower surface of the flange 101a, which is the mouth of the cup container 101, is placed on a first support member 55 described later laid along the peripheral edge of the through hole 13a. In this manner, the cup container 101 is supported by the slats 13 in a necked state with the mouth portion 101a facing upward without falling down.

  As shown in FIGS. 7, 8, and 9 </ b> B, the first support member 55 is a ring-shaped member having substantially the same planar shape as the flange 101 a of the cup container 101, and is fixed to the upper surface of the slat 13. . As shown in FIG. 9A, the first support member 55 is a member having a two-layer structure including a lower layer portion 55b and an upper layer portion 55a, and the lower layer portion 55b is elastically elastically deformed flexibly in accordance with an applied force. For example, it consists of elastic materials, such as urethane rubber, and the upper layer part 55a consists of hard materials, such as a nylon resin harder than the said lower layer part 55b.

  9B, when a downward pressing force is applied to the cup container 101 fitted in the through hole 13a, the lower layer portion 55b of the first support member 55 is compressed and deformed in accordance with the pressing force. The cup container 101 moves downward on the back side of the through hole 13a. On the other hand, if the pressing force is lost, the compression deformation of the lower layer part 55b is eliminated and the cup container 10 moves upward. Returns to the original position before the pressing force is applied.

  As shown in FIG. 8, at the position surrounding the four through holes 13a on the upper surface of the slat 13, the closing sheet continuous body 103e is connected to the cup container at the lid punching position P6 in FIG. 6A. A punching blade 53 for punching into the substantially square shape, which is the shape of the lid portion 103 of the body 102, is fixed upright with its blade edge 53a facing vertically upward. As shown in FIG. 9C, the height of the blade edge 53a is such that the upper surface of the mouth portion 101a of the cup container 101 located at the original position and the upper surface of the reinforcing sheet 105 placed on the second support member 56 described later. Is set lower. This is because the closing sheet continuous body 103e attached to the upper surface of the mouth part 101a at the closing sheet attaching position P4 in FIG. 6A comes into contact with the blade edge 53a before being punched out at the cover part punching position P6. This is to prevent the closing sheet continuous body 103e from being damaged or cut halfway.

  Further, as shown in FIGS. 7 and 8, the second support member is formed over the entire area of the upper surface of the slat 13 from the inner peripheral edge of the extraction blade 53 to the outer peripheral edge of the first support member 55. 56 is laid. The second support member 56 supports the reinforcing sheet 105 when the reinforcing sheet 105 is attached to the back surface of the closing sheet 103 at the closing sheet attaching position P5 in FIG. 6A. Similar to the one support member 55, it is a member having a two-layer structure including an upper layer portion 56a and a lower layer portion 56b. That is, the lower layer part 56b is made of an elastic material such as urethane rubber that is elastically compressed and deformed flexibly according to the applied force, and the upper layer part 56a is harder than the lower layer part 56b, such as a hard material such as nylon resin. Consists of.

  Therefore, when a downward pressing force is applied to the reinforcing sheet 105 placed on the second support member 56, the lower layer portion 56b of the second support member 56 is compressed and deformed according to the pressing force. Then, while the reinforcing sheet 105 moves downward, if this pressing force is lost, the compressive deformation of the lower layer portion 56b is canceled and the reinforcing sheet 105 moves upward. As a result, the pressing force is reduced. It almost returns to the original position before the action.

  The thickness of the second support member 56 is determined by the positional relationship between the height of the upper surface and the height of the upper surface of the mouth portion 101a of the cup container 101 supported by the first support member 55. That is, as shown in FIG. 9C, the thickness is determined such that the upper surface height of the second support member 56 is lower than the upper surface height of the mouth part 101a. And if it becomes such a height relationship, when mounting the reinforcement sheet 105 on the 2nd supporting member 56, it will become easy to position the reinforcement sheet 105. FIG. That is, after the cup container 101 is supported by the through hole 13a as shown in FIG. 9B, the reinforcing sheet 105 is placed on the second support member 56 as shown in FIG. 9C. Since this is higher than the second support member 56 and protrudes upward, each of the holes 105a (see FIG. 4) of the reinforcing sheet 105 is guided to the mouth portion 101a when being mounted. Therefore, the reinforcing sheet 105 is easily positioned at an appropriate position to be placed.

  Further, as shown in FIGS. 7 to 9A, on the upper surface of the slat 13, a cross-shaped sewing blade 71 for forming the aforementioned perforations 103b and 105b on the closing sheet 103 and the reinforcing sheet 105 is erected. Has been. That is, as shown in FIG. 7, while being positioned between the front and rear through holes 13a, 13a of the slat 13, one sewing blade 71 is erected across the left and right direction, and the slat 13 The other sewing blade 71 is erected across the front-rear direction while being positioned between the left and right through holes 13a, 13a, and the sewing blade 71 is provided in a cross shape in plan view. Yes. The height of the cutting edge 71a of the sewing machine blade 71 is set to the same height as the cutting blade 53 as shown in FIG. 9A. Therefore, at the lid punching position P6 in FIG. 6A, perforations 103b and 105b are formed in a cross shape on the closing sheet 103 and the reinforcing sheet 105 simultaneously with the punching operation by the punching blade 53, respectively.

<Cup container loading position P1>
A cup container loading device 19 for loading the cup container 101 into each through hole 13a of the slat 13 is disposed at the cup container loading position P1 in FIG. 6A. That is, while the slat 13 is stopped at the position P1, the cup container 101 is thrown from the cup container loading device 19 toward the four through holes 13a of the slat 13 positioned below the cup container loading device 19. 9B, the cup container 101 is fitted into each through-hole 13a, and the lower surface of the flange 101a serving as the mouth is in contact with and supported by the first support member 55.

<Product filling position P2>
The product filling device 21 is disposed at the product filling position P2 in FIG. 6A. That is, while the slat 13 is stopped at the position P2, the product filling device 21 has a predetermined amount of each measured toward each cup container 101 supported by the slat 13 positioned below the product filling device 21. Product is thrown.

<Reinforcing sheet supply position P3>
At the reinforcing sheet supply position P3 in FIG. 6A, the reinforcing sheet supply device 23 for placing the reinforcing sheet 105 on the second support member 56 of the slat 13 is disposed. That is, while the slat 13 is stopped at the position P3, one sheet shown in FIG. 4 is directed from the reinforcing sheet supply device 23 toward the second support member 56 of the slat 13 positioned below the reinforcing sheet supply device 23. A reinforcing sheet 105 is cast. Then, as shown in FIG. 9C, the reinforcing sheet 105 is placed on the second support member 56 while the corresponding mouth part 101a of the cup container 101 is positioned inside each of the four holes 105a. The

<Closing sheet supply position P4>
In the closing sheet supply position P4 of FIG. 6A, a reel 33 for a closing sheet roll 103r formed by winding a continuous sheet 103e for closing sheets in a roll shape, and a continuous sheet of closing sheets fed out from the reel 33 are provided. A plurality of guide rolls 35 for guiding the body 103e are arranged. Then, the continuous sheet 103e for closing sheet is fed out from the reel 33 in synchronization with the intermittent running of the slats 13, and the continuous body 103e for closing sheet fed out is guided by the guide roll 35 to be cupped. It is applied to the upper surface of the mouth part 101a of the container 101 (see FIG. 10A).

  Note that the lid 103 of the coupling body 102 of the cup container is punched out after passing through the closure sheet pasting position P5 and the lid punching position P6. The punched scrap continuum 103e is continuously wound up and discarded by the take-up reel 37 disposed after the lid punching position P6.

<Blocking sheet pasting position P5>
6A, the closing sheet continuous position 103e applied to the upper surface of the mouth portion 101a of the cup container 101 is attached to the upper surface of the mouth portion 101a, and the closing sheet is attached to the closing sheet sticking position P5. An affixing device 41 for affixing the reinforcing sheet 105 is disposed in a region where the mouth part 101a is not closed on the back surface of the continuous body 103e.

  FIG. 10A and FIG. 10B show a longitudinal sectional view in which a part of the attaching device 41 is enlarged. As shown in FIG. 10A, the affixing device 41 includes a heating plate 43 (corresponding to a pressing member) that is positioned above the slat 13 and can be moved up and down, and a heating plate 43 that is not shown for driving the heating plate 43 up and down. Crank drive mechanism.

  The heating plate 43 has a heating element such as an electric heating coil (not shown) inside, and can raise the surface temperature of the horizontal and flat lower surface 43a of the heating plate 43 substantially uniformly over the entire surface. Then, as shown in FIG. 10B, the heating plate 43 descends toward the stationary slat 13 and comes into contact with the surface of the occluding sheet continuous body 103e. The hot melt adhesive previously applied to the back surface of the closing sheet continuous body 103e is melted by pressing the closing sheet continuous body 103e against the opening 101a of the cup container 101 to heat the opening 101a. A continuous body 103e of the closing sheet is affixed, thereby closing the mouth portion 101a.

  Further, at this time, the portion of the continuous sheet 103e for closing that does not close the mouth portion 101a is heated while being pressed against the reinforcing sheet 105 by the heating plate 43 as shown in FIG. The hot-melt adhesive applied in advance to a portion that does not close 101a melts, and a reinforcing sheet 105 is attached to the portion.

  At the time of this pressing, the pressing force of the heating plate 43 causes the first support member 55 that supports the cup container 101 and the second support member 56 that supports the reinforcing sheet 105 to be compressed and deformed. Although the reinforcing sheet 105 is moved downward, the first support member 55 and the second support member 56 are separate members. Therefore, a mismatch between the cup container 101 and the reinforcing sheet 105 in the positional relationship of the closing sheet with respect to the continuous body 103e (for example, the upper surface height of the mouth portion 101a of the cup container 101 and the upper surface of the reinforcing sheet 105). Even if the height is different, the mismatch is absorbed in the process in which the first support member 55 and the second support member 56 are independently elastically compressed and deformed. As a result, regardless of the arrangement state of the reinforcing sheet 105, the mouth portion 101 a of the cup container 101 is securely attached to the closing sheet continuous body 103 e, while the reinforcing sheet 105 is also attached to the cup container 101. Regardless of the arrangement state of the mouth part 101a, it is securely attached to the continuous body 103e of the closing sheet.

  However, if the amount of downward movement of the closing sheet continuous body 103e during this pressing increases, the closing sheet continuous body 103e contacts the cutting edge 53a of the extraction blade 53 and damages the closing sheet continuous body 103e. End up. Therefore, the receiving beam 45 for restricting the downward movement amount of the continuous body 103e of the closing sheet is disposed below the bottom 101c of the cup container 101 at the closing sheet attaching position P5. Specifically, as shown in FIG. 10A, in a state where the pressing force of the heating plate 43 does not act on the continuous body 103e for the closing sheet, a gap h is formed between the bottom 101c of the cup container 101 and the upper surface of the receiving beam 45. When the cup container 101 is moved downward by applying a pressing force, the receiving beam 45 is disposed at a position where the upper surface height of the mouth portion 101a and the upper surface height of the reinforcing sheet 105 are formed. Before at least one of the blades 53a has the same height as the cutting edge 53a, as shown in FIG. 10B, the bottom portion 101c abuts against the receiving beam 45 and restricts further pushing, so that The upper surface of the part 101a and the upper surface of the reinforcing sheet 105 are made higher than the cutting edge 53a. Therefore, the closing sheet continuous body 103e is not damaged at the closing sheet attaching position P5.

  The hot melt adhesive on the back surface of the continuous sheet 103e for closing is solidified in a short time even after being melted even by air cooling. In order to further shorten this cooling time, Immediately after that, a cooling device (not shown) may be additionally provided. This cooling device is different only in that a cooling water passage as a cooling body is provided instead of the heating element of the pasting device 41, and the other configuration is the same as that of the pasting device 41, and the description thereof is omitted.

<Cover punching position P6>
6A, a pressing device 51 for punching the lid 103 of the coupling body 102 of the cup container from the continuous body 103e of the closing sheet is disposed in cooperation with the punching blade 53 of the slat 13 at the lid punching position P6. Has been.

  11A to 12 show enlarged longitudinal sectional views of a part of the pressing device 51. FIG. The pressing device 51 includes a pressing member 58 that is located above the slat 13 and can be moved up and down, and a cam drive mechanism (not shown) for driving the pressing member 58 up and down. The pressing member 58 is a steel member having a horizontal lower surface. A resin plate 59 such as vinyl chloride is horizontally laid on the lower surface, and the lower surface of the resin plate 59 is also horizontal.

  Then, as shown in FIG. 11B, the pressing member 58 descends toward the stationary slat 13 and comes into contact with the surface of the occluding sheet continuous body 103e. Thereafter, the four cup containers 101 are moved downward. The continuity 103e of the closing sheet is sandwiched between the cutting edge 53a of the extraction blade 53 standing upright on the slat 13 by moving evenly, and as shown in FIG. The lid 103 is punched out.

  Here, at the time of punching, as shown in FIG. 11B, the first support member 55 that supports the cup container 101 and the second support member 56 that supports the reinforcing sheet are compressed and deformed by the pressing force of the pressing member 58. Then, the cup container 101 and the reinforcing sheet 105 move downward so that the upper surface height of the mouth part 101a and the reinforcing sheet 105 is substantially flush with the cutting edge 53a of the extraction blade 53. The body 103e is cut. Therefore, a beautiful lid 103 can be formed as shown in FIG.

  In addition, since the resin plate 59 is arranged on the lower surface of the pressing member 58 and the blade edge 53a contacts the resin plate 59 at the time of punching, the blade edge 53a is not damaged.

  In the punching, cross-shaped perforations 103b and 105b are formed in the substantially square-shaped closing sheet 103 and the reinforcing sheet 105 as the lid. That is, as described above, since the slat 13 is provided with the sewing blade 71 having the same cutting edge height as that of the punching blade 53, the punching sheet 103 is shown in FIG. The reinforcing sheet 105 is sandwiched between the pressing member 58 and the cutting edge 71a of the sewing machine blade 71, so that the closing sheet 103 and the reinforcing sheet 105 have a cross shape of the sewing machine blade 71. Eyes 103b and 105b are formed.

<Unloading position P7>
6A, a carry-out device 61 for taking out the cup container coupling body 102 covered with the closing sheet 103 from the slat 13 and carrying it out of the conveyor 11 is arranged at the carry-out position P7 in FIG. ing. As shown in FIG. 6A, the carry-out device 61 has a take-out head 63 supported so as to be movable up and down and horizontally. The take-out head 63 is provided with a suction cup 65 that sucks the closing sheet 103 of the coupling body 102 of the cup container by a vacuum pump or the like. Then, after the take-out head 63 is lowered onto the closing sheet 103 which is the lid of the coupling body 102 of the cup container, the closing sheet 103 is adsorbed by the suction cup 65, and the take-out head 63 is raised in this adsorbed state. The cup container coupling body 102 is drawn upward from the through-hole 13a of the slat 13 and moved horizontally at this raised position, whereby the cup container coupling body 102 is taken out of the conveyor 11.

=== Variation of Manufacturing Device 1 of Cup Container Linkage 102 ===
FIG. 13A thru | or FIG. 16 is explanatory drawing of the 1st modification of the manufacturing apparatus 1 of the coupling body 102 of a cup container, and a 2nd modification. Each modification is different from the above-described embodiment in the configuration of the pasting device 41 at the closing sheet pasting position P5.

<First Modification>
FIG. 13A and FIG. 13B are enlarged longitudinal sectional views of a part of the attaching device 41 of the first modification. In the pasting apparatus 41 of the above-described embodiment, as shown in FIGS. 10A and 10B, the lower surface 43a (corresponding to the first surface) of the heating plate 43 is a flat surface having no recess over the entire surface. However, as shown to FIG. 13A, the recessed part 44 is formed in the lower surface 43a of the heating plate 43 which concerns on this 1st modification.

  The concave portion 44 is for preventing the heat of the heating plate 43 from being transmitted to a product (not shown) in the cup container 101 when the closing sheet continuous body 103e shown in FIG. Therefore, as shown in FIG. 13B, these recesses 44 correspond to the mouth portion 101 a of the cup container 101 positioned below the heating plate 43 when the heating plate 43 is pressed against the continuous body 103 e of the closing sheet, It is formed in a portion corresponding to the inner side in the radial direction from the corresponding mouth portion 101a.

  Specifically, the inner peripheral surface 44a of each concave portion 44 is positioned along the inner peripheral edge 101d of the corresponding mouth portion 101a, and at least radially inward of the inner peripheral edge 101d. 44 is formed. In this example, since the planar shape of the mouth portion 101a is circular, as shown in the bottom view of the heating plate 43 in FIG. 14, the planar shape of the concave portion 44 has a diameter D44 smaller than the inner diameter Dd of the mouth portion 101a. It is formed in a circle.

  If the diameter D44 of the concave portion 44 is made smaller than the inner diameter Dd of the mouth portion 101a in this way, as shown in FIG. 13B, the closure sheet continuous body 103e is moved by the lower surface 43a of the heating plate 43 to the mouth portion 101a. Can be pressed firmly against.

  Further, at the time of this pressing, the surface temperature of the lower surface 43a of the heating plate 43 is increased so as to melt the hot melt adhesive applied to the back surface of the continuous body 103e of the closing sheet. The air in the space S functions as a heat insulating layer, thereby suppressing the heating of the inner portion 103f of the mouth portion 101a in the closing sheet continuous body 103e. Therefore, the heating of the product filled in the cup container 101 is effectively suppressed, and as a result, the thermal damage of the product can be effectively prevented.

<Second Modification>
15A and 15B are enlarged longitudinal sectional views of a part of a pasting apparatus 41 according to a second modification. In the pasting device 41 of the first modified example described above, as shown in FIG. 13A, the one-step recess 44 is formed on the lower surface 43 a of the heating plate 43, but the heating plate 43 of the second modified example has Two-step recesses 47 and 48 are formed on the lower surface 43a. That is, a second recess 47 (corresponding to the second recess) is formed on the lower surface 43a of the heating plate 43 according to the second modified example, and further, a horizontal and flat inner side of the second recess 47 is formed. A first recess 48 is formed on the bottom surface 47b.

  The 1st recessed part 48 is the same as the recessed part 44 of the above-mentioned 1st modification. That is, in order to prevent thermal damage to the product in the cup container 101, it is formed in a circular shape with a diameter R44 with the same specifications as the first modification.

  On the other hand, the second concave portion 47 surrounding the outside of the first concave portion 48 is formed for the purpose of securely sticking the reinforcing sheet 105 to the closing sheet continuous body 103e. More specifically, when pressing the closing sheet continuous body 103e against the mouth portion 101a and the reinforcing sheet 105 by the heating plate 43, as described above with reference to FIGS. 10A and 10B, the first support member 55 and The second support members 56 are elastically compressed and deformed respectively. The occluding sheet continuous body 103e is pressed against the mouth portion 101a by the pressing pressure generated based on the elastic compressive deformation amount of the first support member 55, and is generated based on the elastic compressive deformation amount of the second support member 56. The closing sheet continuum 103e is pressed against the reinforcing sheet 105 by the pressing pressure, and based on the magnitude of the pressing pressure, the mouth portion 101a and the reinforcing sheet 105 of the closing sheet continuum 103e are pressed. The adhesive strength of each pasting is determined.

  In this regard, when the top surface height of the mouth portion 101a of the cup container 101 is slightly higher than the top surface height of the reinforcing sheet 105 as in the example of FIG. The amount of elastic compressive deformation of the second support member 56 is slightly smaller than the amount of elastic compressive deformation of the first support member 55, and the pressing pressure of the continuous body 103e for closing in the pressed state of FIG. The reinforcing sheet 105 is smaller than the mouth part 101a. However, in the case of the example of FIG. 10A, since the difference in the upper surface height is small, the difference in the pressing pressure is also small, so that not only the mouth portion 101a but also the reinforcing sheet 105 is closed with an appropriate adhesive force. It is affixed on the continuous body 103e for the sheet.

  On the other hand, as shown in FIG. 15A, when the upper surface height of the mouth portion 101a of the cup container 101 is very high as compared with the upper surface height of the reinforcing sheet 105, the heating plate 43 When the continuum 103e is pressed against the mouth portion 101a and the reinforcing sheet 105, the difference in the amount of elastic compression deformation between the first support member 55 and the second support member 56 becomes very large. Compared to the pressing pressure of the continuous body 103e against the mouth portion 101a, the pressing pressure of the continuous body 103e against the reinforcing sheet 105 is significantly reduced. As a result, the adhesive force of the occluding sheet continuous body 103e to the reinforcing sheet 105 becomes extremely weak, and there is a risk of causing poor attachment.

  Therefore, in the manufacturing apparatus 1 of the second modification, as shown in FIG. 15A, the difference in the upper surface height between the mouth portion 101a and the reinforcing sheet 105 is prevented in order to prevent such a sticking failure of the reinforcing sheet 105. The second concave portion 47 having substantially the same depth is formed on the lower surface 43a of the heating plate 43, thereby reducing and reducing the influence of the difference in the upper surface height on the pressing pressure, so that the continuous body 103e for the closing sheet is formed. Thus, the reinforcing sheet 105 is securely attached. That is, as shown in FIG. 15B, the closing sheet continuous body 103e is pressed against the mouth portion 101a by the bottom surface 47b of the second recess 47, and the closing sheet continuous body 103e is reinforced by the lower surface 43a of the heating plate 43. The sheet is pressed against the sheet 105 for use.

  As shown in FIG. 15B, the second concave portion 47 having such a function is formed in the mouth portion 101 a of the cup container 101 positioned below the heating plate 43 when the heating plate 43 is pressed against the closing sheet continuous body 103 e. It is formed so as to cover the corresponding mouth part 101a.

  Specifically, as shown in FIG. 15A, the inner peripheral surface 47a of each recess 47 is along the outer peripheral edge 101e of the corresponding mouth part 101a, and at least the occluding sheet is more continuous than the outer peripheral edge 101e. The second recess 47 is formed so that the thickness of the body 103e is positioned on the outer side in the radial direction. In this example, since the planar shape of the mouth portion 101a is circular, as shown in the bottom view of the heating plate 43 in FIG. 16, the planar shape of the second recess 47 has a diameter D47 larger than the outer diameter De of the mouth portion 101a. However, at least the thickness of the continuous body 103e of the closing sheet is formed in a large diameter circle.

=== Other Embodiments ===
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to this embodiment, The deformation | transformation as shown below is possible.

  In the above-described embodiment, as an example of the coupling body 102 of the cup container, a mode in which four cup containers 101 as shown in FIG. However, the present invention is not limited to this. For example, a cup container coupling body 102a in which three cup containers 101 are arranged in a line may be used. Also in this case, as shown in the plan view of the coupling body 102a of the cup container as seen from the back side in FIG. 17A and the same side view of FIG. 17B, the reinforcing sheet 105 is on the back side of the closing sheet 103. Needless to say, it is affixed only to a region where the mouth portion 101a is not closed.

  In the above-described embodiment, the cup container 101 is made of paper. However, the material is not limited to this, and may be made of resin. In this case, according to the above-described embodiment, the cup containers 101, 101 are connected and integrated by the closing sheet 103, so that the flange 101a is greatly extended so as to be connected and integrated by the flange 101a as the mouth. As a result, the amount of resin required for forming the flange can be reduced.

  In the above-described embodiment, silica-deposited paper or polyethylene-coated paper is exemplified as the closing sheet 103. However, the sheet is not limited to this as long as it is an airtight sheet having airtightness. For example, a resin sheet such as vinyl may be used. However, when a resin sheet is used, it is inferior in recyclability as compared with a paper sheet.

  In the above-described embodiment, thick paper is used as the reinforcing sheet 105. However, the present invention is not limited to this as long as it is a sheet that can be attached only to a region where the mouth portion 101a on the back surface of the closing sheet 103 is not closed. For example, a resin sheet may be used. However, when a resin sheet is used, it is inferior in recyclability as compared with a paper sheet.

  In the above-described embodiment, the cup container 101 having a flange in the mouth portion 101a is illustrated as the cup container 101. However, the present invention is not limited to this, and a curled portion curled outwardly over the entire circumference of the mouth portion 101a. The cup container 101 provided may be used.

  In the above-described embodiment, the case where the body portion 101b of the cup container 101 is a tapered cylindrical paper tube is illustrated. However, the present invention is not limited to this, and the outer diameter of the body portion 101b of the cup container 101 is in the height direction. A constant straight tube may be used over the entire area. The planar shape of the cup container 101 is not limited to a circle, and may be a rectangle or a polygon. In this case, it goes without saying that the through-hole 13a is formed in a shape corresponding to the planar shape of the cup container 101 so that the cup container 101 can be fitted therein.

  In the above-described embodiment, as illustrated in FIG. 5B, the reinforcing sheet 105 is exemplified by a sheet whose outer contour is slightly smaller than the closing sheet 103. However, the present invention is not limited to this example. It may be the same size as the sheet 103, and the outer contour of the reinforcing sheet 105 may protrude beyond the closing sheet 103. However, even if the reinforcing sheet 105 having a size that protrudes beyond the closing sheet 103 is used, when the processing is performed using the manufacturing apparatus 1 described above, the reinforcing sheet 105 is used as the closing sheet. The sheet is trimmed to the same size as the outer contour of the closing sheet 103 without protruding from the sheet 103. This is because when the punching blade 53 in FIG. 8 punches the closing sheet 103 from the closing sheet continuous body 103e at the lid punching position P6 of the manufacturing apparatus 1, the punching blade 53 causes the closing sheet 103 to be removed. This is because the portion that protrudes outside the outer contour is cut off.
