Description

  The present invention relates to an overlap package in which an overlap package is applied to a package body such as a cup-made instant ramen or cup-type instant udon using a wrapping material made of a shrink film, and a method for packaging the same.

  Conventionally, with regard to cup-containing products such as instant udon in cups and instant ramen in cups, the product name, design, etc. are preliminarily placed on the cup-shaped or bowl-shaped container body and the sheet-like lid member that closes the mouth of the container body. After being printed, the contents are stored in the container body, the mouth is closed with a lid member, and then sold in a state of being overlap-wrapped using a packaging material formed of a transparent shrink film.

  However, compared to printing the product name, design, etc. on the container body or lid member, the printed part is better printed with the product name, design, etc. on the wrapping material itself formed by shrink film for applying the overlap wrapping. In recent years, when the mouth of the container body is closed by the lid member, it is not necessary to consider the alignment between the printed part of the container body and the printed part of the lid member. It is desired to perform overlap wrapping using a packaging material on which product names, designs, etc. are printed in advance without printing on the member. For many cupped products, etc., the inner surface is already abbreviated. Overwrap packaging has been applied using a packaging material with a characteristic pattern or background printed on the entire surface.

JP-A-53-125186

  By the way, when displaying such cupped products (hereinafter, cupped products are referred to as “packaged bodies” and cupped products overwrapped are referred to as “overlap packed bodies”) As shown in FIG. 8, a front surface portion on which a product name, a pattern, etc. are printed on the front side of an overlap package group in which a plurality of overlap packages 50 are stacked up and down is easy to see. It is common to display the two overlap packages 50 in a standing state so as to be held by the rear overlap packages, but the cups used for instant ramen with cups, instant udon with cups, etc. In order to make it easier to drink soup and juice, the shape of the bowl-shaped or bowl-shaped container is usually circular in its mouth and cylindrical in shape, so it overlaps the rear. The overlapped packaging 50 on the front side displayed in a standing state so as to be held on the body group easily rolls in the horizontal direction, and the product names, designs, etc. displayed on the top surface are inclined. Therefore, there is a problem that the store clerk has to frequently correct the display posture so that the product names, symbols, etc. displayed on the top surface do not tilt.

  In order to solve these problems, in the case of displaying in an upright state by partially forming a flat surface on the outer peripheral surface of the body of the container or by forming a plurality of protrusions in the circumferential direction It is conceivable to prevent the overlap package from rolling, but to prevent the overlap package from rolling by such a method, the portion of the top surface of the overlap package that faces upward when it stands is Because it is specified, when wrapping the packaged body with a packaging material with a characteristic pattern or background printed on almost the entire inner surface, when wrapping the packaged material with the packaging material The positioning of the package body and the packaging material is performed.

  However, since the packaging material that wraps the package body usually has a planar shape close to a rectangle, in the case of a package body whose top surface is substantially circular, as shown in FIG. Since the planar shape of the wrapping material 52 covering the body 51 and the top surface shape of the wrapping body 51 are greatly different, the positions of the wrapping body 51 and the wrapping material 52 before the wrapping body 51 is wrapped by the wrapping material 52. Even if they are aligned, the packaging material 52 is formed in a cylindrical shape so as to cover the top surface and the bottom surface of the packaging material 51 in order to wrap the packaging material 51 with the packaging material 52, and then both ends of the packaging material 51 are opened. When the part is sandwiched between the sealing bars and melted and sealed, the packaging material 52 is likely to be displaced with respect to the packaged body 51, and when the packaged body 51 is displayed in a standing state, the top of the packaged body 51 is displayed. The product name or design displayed on the surface is slightly inclined. There is a problem that.

  Accordingly, an object of the present invention is to provide an overlapped packaging body and a packaging method for the same, which are less likely to roll in the lateral direction and the top surface design is less likely to be displaced even when displayed in an upright state. is there.

  In order to solve the above-mentioned problems, the invention according to claim 1 is characterized in that the contents are stored in a cup-shaped or bowl-shaped container having a flange portion projecting radially outward from a circular upper end opening, and the upper end opening is formed. In the state where the packaged body made of a shrink film is formed in a cylindrical shape so as to cover the top and bottom surfaces of the closed packaged body, and the peripheral surface side of the packaged body opened in the packaging material is fused and sealed, In the overlap package in which the packaging material is heat-shrinked, the flange portion has a convex portion with an outer edge partially protruding outward, and the fusion seal in the convex portion of the flange portion and the packaging material It is an object of the present invention to provide an overlap package characterized in that the package body is wrapped by the packaging material so that the end portions of the parts correspond to each other.

  In order to solve the above-mentioned problem, the invention according to claim 2 includes a flange portion projecting radially outward from the circular upper end opening, and the flange portion has its outer edge partially projecting outward. Packaging of an overwrapping body in which the contents are housed in a cup-shaped or bowl-shaped container having a convex portion and the upper end opening is closed and the overwrapping is performed using a packaging material made of a shrink film In the method, after forming the packaging material in a cylindrical shape so as to cover the upper surface and the bottom surface of the packaged body, fusing and sealing the peripheral surface side of the packaged body opened in the packaging material, A step of wrapping the package body with the wrapping material; and a step of heat-shrinking the wrapping material wrapped with the package body, and the convex portion of the flange portion when the package body is wrapped with the packaging material Before To face the end side of the heat-sealing portion in the packaging material, wherein there is provided a method of packaging a overlap packaging body, characterized in that a target package with respect to the packaging material.

  As described above, in the overlap package of the invention according to claim 1, since the flange portion of the container constituting the package body has a convex portion whose outer edge partially protrudes outward. In addition, when this overlapping package is placed on the mounting surface with the outer peripheral surface of the body portion of the container facing down, the mounting surface includes point contacts or convex portions at a plurality of locations including the convex portion on the outer peripheral edge of the flange portion. As in the case where a flat surface and a plurality of protrusions are formed on the outer peripheral surface of the container body, the container outer surface is faced down and placed on the mounting surface. The overlap package is less likely to roll laterally.

  Further, in this overlap package, since the flange portion of the container constituting the package body has a convex portion whose outer edge partially protrudes outward, the packaging of the invention according to claim 2 As in the method, when the package body is wrapped with the packaging material, the package body is arranged with respect to the packaging material so that the convex portion of the flange portion faces the end portion side of the fusing seal portion of the packaging material. When the packaging material is fused and sealed, the convex portion of the flange portion of the package body is caught at the corner portion of the packaging material where the planar shape is close to a rectangle. The wrapping material comes into close contact with the package body with the convex portion of the flange portion and the end of the fusing seal portion of the wrapping material corresponding to each other. When it is displayed in the It can be subjected to over-wrap packaging in an appropriate state of trade names, designs, or the like to be displayed on the top surface portion does not tilt.

  Hereinafter, embodiments will be described with reference to the drawings. As shown in FIG. 1 and FIGS. 2 (a) and 2 (b), this overlap package 1 is made of a cup of instant noodles containing contents such as instant noodles and medicines (hereinafter referred to as packaged bodies). 2) is wrapped with a wrapping material 3 formed of a shrink film (for example, a biaxially stretched polypropylene film). Solid printing is performed on substantially the entire inner surface so that a product name, a characteristic pattern, and the like are displayed on a portion covering the surface and the peripheral surface.

  As shown in FIGS. 3A to 3C, the container 10 includes a bowl-shaped container body 11 having a flange portion 12 projecting radially outward from an upper end edge, and an upper end opening 13 of the container body 11. The lid sheet 15 is closed, and the contents are sealed in the container body 11 by heat-sealing the lid sheet 15 to the flange portion 12 in a state where the contents are accommodated in the container body 11. It is like that.

  As shown in FIGS. 3A to 3C, the container body 11 has an upper end opening 13 formed in a circular shape, but a bottom 14 formed in a square shape having an R-shaped corner. The flange portion 12 has two convex portions 12a and 12b protruding outward in the radial direction so that the outer edges thereof correspond to two adjacent corner portions of the bottom portion 14 formed in a square shape. ing.

  As shown in FIG. 4, the bottom 14 formed in a square shape in the container 10 includes the packaged body 2 in which the contents are accommodated in the container 10 configured as described above and the mouth is closed with the lid sheet 15. The two protruding portions 12a and 12b in the flange portion 12 of the container 10 are positioned on one side of the conveyance path by causing the two opposite sides of the container 10 to be along a pair of guide rails G installed on both sides of the conveyance path. Using the horizontal pillow wrapping machine, the top and bottom surfaces of the package body 2 are covered with the packaging material 3 while the conveyance posture is held constant, and the packaging material 3 is covered with the bottom surface side of the packaging body 2. After forming the tube by center sealing by performing a fusing seal or the like at the front and back of the package 2, the opened peripheral surface side of the package 2 in the packaging material 3 is melt-sealed (lateral seal) ) 5 (a) and 5 (b), the convex portions 12a and 12b of the flange portion 12 face the one end e side of each fusing seal (lateral seal) portion S2 in the packaging material 3 and Since the body 2 is wrapped by the packaging material 3, when the packaging material 3 is heated and shrunk in this state, as shown in FIGS. 1 and 2, the fusion seals in the convex portions 12 a and 12 b of the flange portion 12 and the packaging material 3 are obtained. In a state where the ends e of the portion S2 correspond to each other (a state in which the positions in the circumferential direction of the container 10 are substantially coincident), the overlap packaging body 1 in which the packaging material 3 is in close contact with the packaging body 2 is completed. In FIG. 5A, reference numeral S1 denotes a center seal portion.

  As described above, in the overlap package 1, the flange portion 12 of the container 10 constituting the package body 2 has convex portions 12 a and 12 b whose outer edges partially protrude outward. Therefore, for example, as shown in FIGS. 6 (a) and 6 (b), it is easy to see the top surface portion on which the product name, the design, etc. are greatly printed on the front side of the plurality of overlapping packages 1 stacked one above the other. Thus, even when displaying in the state where one overlap package 1 is stood up, the overlap package 1 in the stand-up state has the flange portion 12 on the mounting surface at the outer edge portions of the convex portions 12a and 12b. Since it is in line contact, it does not roll in the horizontal direction and can always maintain an appropriate display posture.

  In addition, as described above, when the wrapped package 2 is wrapped with the packaging material 3, the overlap package 1 has the convex portions 12 a and 12 b of the flange portion 12 at one end e side of the fusing seal portion S 2 in the packaging material 3. By placing the packaged body 2 on the packaging material 3 so as to face, the packaging material 3 is packaged at the corner of the packaging material 3 where the planar shape is close to a rectangle when the packaging material 3 is fused and sealed. Since the convex portions 12a and 12b of the flange portion 12 in the body 2 are caught, the packaging material 3 is less likely to be displaced with respect to the packaged body 2, and the convex portions 12a and 12b of the flange portion 12 and the packaging material 3 are always melted. The packaging material 3 comes into close contact with the package body 2 in a state where the one end e of the seal portion S2 corresponds to each other. When the overlap packaging body 1 is displayed in a standing state, the package body 2 Displayed on the top surface of It can be subjected to over-wrap packaging in an appropriate state of trade names, designs, or the like is not inclined.

  In addition, the overlap package 1 is formed on the outer side in the radial direction of the container body 11 so that the convex portions 12a and 12b of the flange portion 12 correspond to two adjacent corner portions of the bottom portion 14 formed in a square shape. Since it overhangs, the display area of the top surface portion can be increased without increasing the display space, as compared with the conventional overlapped packaging body in which the flange portion does not have a convex portion. .

  In addition, when the planar shape of the packaged body is circular, the planar shape close to the rectangle of the packaging material that wraps the packaged body is significantly different from the planar shape of the packaged body. Even if the corner of the packaging material shrinks to the maximum extent within the range of the shrinkage characteristics of the shrink film that forms the packaging material, the distance from the package becomes extremely large compared to other parts, There is a problem that the corner portion of the packaging material protrudes outwardly without being in close contact with the packaged body, that is, a so-called “sticking phenomenon” occurs. The packaging material 3 so that the portions 12a, 12b face the one end e side of the fusing seal part S2 in the packaging material 3, that is, the convex portions 12a, 12b of the flange portion 12 protrude toward the corner portion side of the packaging material 3. 2 to be packaged In the state, since the packaging material 3 is so as to heat shrinkage, there is also an effect that the convex portion 12a of the flange portion 12, "one out phenomenon" of the packaging material 3 to be generated in the vicinity 12b are suppressed. In addition, since the packaging material 3 is drawn toward the convex portions 12a and 12b during the heat shrinkage, the “sticking phenomenon” on the side of the flange portion 12 where the convex portions are not formed is also suppressed.

  In the above-described embodiment, the container body 11 that protrudes outward in the radial direction so that the convex portions 12a and 12b of the flange portion 12 correspond to two adjacent corner portions of the bottom portion 14 formed in a square shape is employed. However, the present invention is not limited to this. For example, as shown in FIG. 7A, the flange portion 12A has a radial direction so as to correspond to each corner portion of the bottom portion 14 formed in a square shape. It is also possible to employ a container body 11A having four projecting portions 12a to 12d projecting to the outside. When such a container body 11A is employed, the display area of the top surface of the packaged body is ensured to the maximum. be able to.

  In addition, as shown in FIG. 2B, the flange portion 12B has two bulges radially outward so as to correspond to the two corner portions located on the diagonal line of the bottom portion 14 formed in a square shape. It is also possible to employ a container main body 11B having convex portions 12a and 12b. When such a container main body 11B is employed, in order to improve the self-supporting stability, the container main body 11B comes into line contact with the mounting surface when standing. In addition, it is desirable to keep the straight portions at the outer edges of the convex portions 12a and 12b as long as possible.

  Moreover, when providing two convex part 12a, 12b on the diagonal of the bottom part 14 formed in square shape, it is also possible to use convex part 12a, 12b as a handle, In that case, in order to raise intensity | strength In addition, it is desirable to form ribs on the convex portions 12a and 12b.

  Moreover, in each embodiment mentioned above, although the flange parts 12, 12A, 12B have the convex parts 12a-12d which have the linear part which carries out a line contact to a mounting surface when it stands, it is limited to this. For example, as shown in FIG. 2C, it is possible to adopt a container body 11C in which the outer edges of the convex portions 12a and 12b of the flange portion 12C are all formed by curves. In this case, the convex portions 12a and 12b of the flange portion 12C make point contact with the placement surface.

  Moreover, in each embodiment mentioned above, although the flange parts 12, 12A, 12B, 12C have several convex part 12a-12d, it is not limited to this, For example, the same figure (d). It is also possible to adopt a container body 11D in which the flange portion 12D has only one convex portion 12a, as shown in FIG. 2, and in this case, the convex portion 12a of the flange portion 12D and the convex portion in the flange portion 12D The point other than 12a makes point contact with the mounting surface, thereby preventing rolling.

  Further, when the flange portion of the container body has a plurality of convex portions, when wrapping the package body with the packaging material, at least one convex portion is at one end side of the fusing seal portion in the packaging material (any one of the packaging materials). If it is made to face the corner, the position of the packaging material can be prevented from being displaced at the fusing and sealing stage. It is desirable to provide it at a position that faces the end side of the portion (the other corner portion of the packaging material).

  Moreover, in each embodiment mentioned above, although the container main body by which the bottom part is formed in square shape is employ | adopted, it is not limited to this, In the stage before wrapping a to-be-packaged body with a packaging material, a packaging material If the direction of the body to be packaged can be regulated, it is possible to adopt a container body having a bottom formed in a circular shape.

  In the above-described embodiment, the case where the container body 11 uses the bowl-shaped container 10 has been described. However, the present invention is not limited to this, and the body of the container body is a tapered cylindrical cup-shaped container. Needless to say, it can be applied to the case of use.

  In the above-described embodiment, the upper end opening 13 of the container body 11 is closed by heat-sealing the lid sheet 15 to the flange part 12 of the container body 11. However, the present invention is not limited to this. Instead, it is also possible to close the upper end opening of the container body by fitting a sheet-molded lid member to the flange portion. You may provide the convex part which matched the part.
