  By the way, in the multipack package made of paper, the articles to be packaged arranged at the end of the row may easily fall off at the time of sale. In addition, when the package is opened, a plurality of packages are in a disassembled state. For example, even when one package is used, disassembly of a package form in which a plurality of packages is collected Will be forced.

  In a package using a shrink film, it is possible to prevent the packaged articles from falling off, but, like a multipack package, a plurality of packages to be packaged fall apart. In addition, since a heating device such as a hot air heater is used in the heat shrinking process of the shrink film, the facilities are large and a large amount of electric power is required in the manufacturing process.

  That is, an object of the present invention is to provide a packaging body that does not use a shrink film, and that can individually remove the packaged article and can prevent the packaged article from dropping out at the time of sale. .

  The packaging body according to the present invention is a packaging body for packaging a plurality of articles to be packaged, wherein the stretch film is formed into a cylindrical shape, and a plurality of cylindrical labels to be attached to each article to be packaged are provided. And each cylindrical label is connected to each other by a joint.

  According to the said structure, a several to-be-packaged item can be packaged collectively. The package is provided with a cylindrical label made of stretch film that is attached to each packaged item. The required number of packages can be extracted individually. In addition, since the cylindrical label is made of a stretch film, unlike the shrink film, the packaged item can be easily held and extracted without being thermally contracted.

In the package according to the present invention, the article to be packaged includes a first end surface portion, a second end surface portion disposed to face the first end surface portion, a first end surface portion, and a second end surface portion. It is preferable that the cylindrical label is mounted from at least the peripheral edge of the first end surface portion to the middle portion of the side surface portion.
Alternatively, the article to be packaged connects the first end surface portion, the second end surface portion opposed to the first end surface portion, the first end surface portion and the second end surface portion, and in the circumferential direction. It is preferable that the cylindrical label is mounted so as to cover the stepped portion of the side surface portion. Moreover, when the level | step-difference part of a side part is formed in the vicinity of a 1st end surface part, a cylindrical label may be mounted | worn over the middle part of a side part from at least the periphery of a 1st end surface part. preferable.

  In the said structure, the cylindrical label is provided to the middle part of the side part rather than the 2nd end surface part. For this reason, when extracting the package from the package, the exposed part of the package not covered with the cylindrical label is gripped and pulled downward so that the package is rotated. Objects can be extracted easily. Moreover, when extracting a to-be-packaged item from a cylindrical label, it can prevent that the edge part of a cylindrical label gets caught in a level | step-difference part.

The packaging body according to the present invention preferably includes a holding member including a joining portion for joining the cylindrical labels, and the cylindrical labels are coupled to each other via the holding member.
According to the said structure, since each cylindrical label is connected by the holding member, the coupling | bonding force of each to-be-packaged object with which the cylindrical label was mounted | worn increased, and the stable packaging form can be provided.

The holding member includes a top plate that covers the first end surface portion of each packaged object, and a side that extends from the top plate to the second end surface side of each packaged object and covers the side surface portion of each packaged object. It is preferable that a joining part is provided in the side plate including the face plate.
According to the said structure, the coupling | bonding force of each to-be-packaged product can further be raised, and the more stable packaging form can be provided.

Moreover, it is preferable that a holding member contains at least a pair of side plate mutually opposingly arranged on both sides of the some to-be-packaged goods located in a line or several rows.
According to this configuration, it is possible to stably maintain a good-looking packaging form in which a plurality of packages are arranged.

  The package according to the present invention can suppress the dropout of the package at the time of sale, while enabling individual extraction of the package at the time of use. Moreover, since no shrink film is used, the amount of power used in the manufacturing process can be reduced.

It is a perspective view which shows the package which is embodiment of this invention. It is a side view which shows the package which is embodiment of this invention. In the package which is embodiment of this invention, it is sectional drawing which shows the top | upper surface part vicinity of a to-be-packaged object.

It is a figure which shows the 1st modification of the package which is embodiment of this invention. It is a figure which shows the 2nd modification of the package which is embodiment of this invention. It is a figure which shows the 3rd modification of the package which is embodiment of this invention.

  Embodiments of a package according to the present invention will be described in detail with reference to the drawings.

  In the embodiment, the substantially cylindrical container 20 suitable for a beverage can (canned beer / canned coffee) filled with beer, coffee, or the like is illustrated as an object to be packaged, but application of the present invention is not limited thereto. For example, the present invention can be applied to bottles and synthetic resin containers (for example, PET bottles) having various shapes.

  Moreover, although embodiment demonstrates each packaged object packaged by one package body as what has the same shape, it is not limited to this. For example, the form from which all shapes differ among a plurality of to-be-packaged goods, and the form from which only one shape differs can be illustrated.

  In the embodiment, for convenience of explanation, terms indicating directions such as “up and down” and “left and right” are used, but the relationship between each component and the direction is not limited. Hereinafter, the axial direction of the cylindrical label 11 and the container 20 is referred to as “vertical direction”, and the side on which the cylindrical label 11 and the holding member 12 are provided is referred to as “upper”. In addition, a direction along the row 30 is a “left-right direction”, and a direction perpendicular to the paper surface of FIG. 1 is a “front-rear direction”.

  The configuration of the package 10 will be described in detail with reference to FIGS. FIG. 1 is a perspective view of the package 10, and FIG. 2 is a side view of the package 10. FIG. 3 is a cross-sectional view showing the vicinity of the top surface portion 21 and shows a state in which the cylindrical label 11 and the holding member 12 are cut along the vertical direction. FIG. 4 is a view showing a state in which the container 20 is extracted from the cylindrical label 11 and shows a state in which the top plate 13 is directed downward.

  As shown in FIG.1 and FIG.2, the package 10 forms the stretch film in the cylinder shape, and joins each cylindrical label 11 and the some cylindrical label 11 with which each container 20 is each mounted | worn. And a holding member 12 including joint portions 15a and 15b. In the package 10, the cylindrical labels 11 are coupled to each other via the holding member 12. That is, the packaging body 10 includes a plurality of cylindrical labels 11 and a single holding member 12, and a plurality of containers 20 to which the cylindrical labels 11 are attached are coupled to each other, and the plurality of containers 20 are packaged together.

  The package 10 has a packaging form in which three containers 20 are arranged in a row (this row is referred to as “row 30”). In the package 10, all the containers 20 are packaged in a state where the top surface portion 21 as the first end surface portion faces the same direction. At the time of sale, it is usually displayed so that the top surface portion 21 is positioned vertically upward. Further, the three containers 20 are in contact with the adjacent containers 20. That is, the row 30 is formed by connecting the three containers 20 in a straight line.

  The container 20 is, for example, a metal beverage can. The container 20 includes a top surface portion 21 that is a first end surface portion in which a content outlet (not shown) is formed, and a bottom surface portion 22 that is a second end surface portion that is disposed to face the top surface portion 21. A side surface portion 23 that connects the top surface portion 21 and the bottom surface portion 22 is included. The top surface portion 21 and the bottom surface portion 22 are parallel to each other, and both have a substantially circular shape. The side surface portion 23 is a curved surface portion formed along the circular shape, and the container 20 has a substantially cylindrical shape as a whole. Further, the container 20 is provided with a tightening portion 24 at the upper end of the side surface portion 23.

  Here, the winding part 24 is formed by, for example, so-called double winding. Double winding is a method in which the curled portion of the can lid constituting the top surface portion 21 is wound around the flange portion of the can body constituting the side surface portion 23 and is crimped and sealed. As a result, the top surface portion 21 has a dish-like wall on the periphery thereof, and the diameter of the upper end of the side surface portion 23 is increased. In the container 20, a concave portion 25 is formed in the lower part of the tightening portion 24 over the entire circumference of the side surface portion 23, and the steep diameter of the side surface portion 23 is formed at the boundary between the tightening portion 24 and the concave portion 25. A step portion having a change is formed in the circumferential direction of the side surface portion 23. In addition, in this level | step-difference part, the direction where a diameter becomes large and the direction where the container 20 moves when extracting the container 20 from the cylindrical label 11 are reverse.

  The cylindrical labels 11 are respectively attached in close contact with the side surface portions 23 of the containers 20. In the form illustrated in FIG. 1, the cylindrical label 11 is mounted so as to cover about the upper 2/3 of the side surface portion 23 from the upper end portion to the midway portion of the side surface portion 23. That is, the cylindrical label 11 is attached to the upper end portion side of the side surface portion 23 in a biased manner. The axial length of each cylindrical label 11 is not particularly limited as long as the container 20 can be held. However, the bottom length 22 is shorter than the axial length of the container 20 so that the container 20 can be easily pulled out during use. It is preferable that it is not applied.

  As described above, the cylindrical label 11 is formed by forming a stretch film into a cylindrical shape, and has a diameter smaller than the diameter of the container 20 before mounting. And the cylindrical label 11 is mounted | worn with the container 20 in the state extended | stretched to radial direction. For this reason, the shrinkage force which tries to return to the original size is acting on the cylindrical label 11. FIG. The cylindrical label 11 made of a stretch film can hold the container 20 by tightening the container 20 due to its excellent stretch characteristics (stretch characteristics). In addition, although the applicable stretch film is not specifically limited, a suitable thing is mentioned later.

  As shown in FIGS. 3 and 4, the cylindrical label 11 has a top surface covering portion 16. It is preferable that the cylindrical label 11 covers the winding fastening part 24 and covers at least the peripheral edge of the top surface part 21 beyond the winding fastening part 24. The portion covering the top surface portion 21 is the top surface covering portion 16. Although the top surface covering portion 16 may cover a wide range on the top surface portion 21, it is preferable that the top surface covering portion 16 is provided in a ring shape that covers only the periphery of the top surface portion 21 from the viewpoint of reducing the material cost. That is, it is preferable that the cylindrical label 11 is mounted so as to cover a step portion existing at the boundary between the tightening portion 24 and the concave portion 25 from at least the periphery of the top surface portion 21 to the middle portion of the side surface portion 23. is there.

Moreover, the cylindrical label 11 has the center seal | sticker part 17 (refer FIG. 4). The cylindrical label 11 is formed into a cylindrical body by joining the edges of the stretch film (so-called center seal) to form the center seal portion 17. The center seal portion 17 is a joint portion for maintaining the cylindrical shape of the stretch film, and is preferably formed by an adhesive or by heat sealing. The adhesive is not particularly limited, and a thermoplastic resin-based or elastomer-based adhesive can be applied.
Further, the cylindrical label 11 is not limited to the one having the center seal portion 17. For example, the tubular label 11 includes a stretchable tubular body that is formed into a tubular shape by extruding a molten resin into a tubular shape by inflation molding.

  The holding member 12 includes a plate-like body (hereinafter also referred to as “sheet”) that is bent so as to wrap around the plurality of containers 20 to which the cylindrical labels 11 are attached. In the form illustrated in FIG. 1, the holding member 12 is provided so as to cover the portion of each container 20 where the cylindrical label 11 is mounted. The holding member 12 joins the respective cylindrical labels 11 so that the axial directions of the respective cylindrical labels 11 are parallel to each other and the three containers 20 are arranged to form a row 30. Each container 20 is held.

  As the plate-like body constituting the holding member 12, for example, a resin sheet or a sheet having a paper material as a main base material can be used. Preferably, a sheet whose main material is paper is used. Examples of the sheet having a paper material as a main base material include a thick paper made only of paper, a synthetic paper in which various types of resin are coated on a paper sheet, or a resin sheet is laminated. The thickness of the sheet is set in consideration of rigidity and workability, and is preferably about 0.2 to 2 mm, and more preferably about 0.5 to 1.5 mm.

  The holding member 12 includes a top plate 13 that covers the top surface portion 21 of each container 20, and a pair of side plates 14 a that extend from the top plate 13 toward the bottom surface portion 22 side of each container 20 and cover the side surface portion 23 of each container 20. 14b. Since the holding member 12 covers the top plate 13, it is possible to prevent the takeout port from becoming dirty. The top plate 13 is arranged substantially parallel to the radial direction of the container 20, and the pair of side plates 14a, 14b are arranged substantially parallel to the axial direction of the container 20 so as to cover the front and rear of the row 30, respectively. It has an elongated, substantially rectangular shape. The lengths in the left-right direction of the top surface portion 21 and the side plates 14 a and 14 b are the same and are substantially the same as the lengths of the rows 30.

  The side plates 14a and 14b are arranged to face each other with the three containers 20 arranged in a row, that is, the row 30 in between. The side plates 14 a and 14 b have substantially the same size and extend below the cylindrical label 11. The top plate 13 and the side plates 14a and 14b are preferably formed by bending one sheet in the same direction. For example, one sheet is bent so that the side plate 14 a and the side plate 14 b are substantially parallel to each other and substantially perpendicular to the top plate 13.

  The side plates 14a and 14b have joint portions on the surfaces facing each other, that is, on the surface facing the container 20 (hereinafter referred to as “back surface”, and the surface facing the opposite side of the container 20 is referred to as “front surface”). 15a and 15b are provided, respectively. In the package 10, the cylindrical labels 11 are joined to each other by being joined to the holding member 12 by the joining portions 15a and 15b. The joining portion 15a is formed in a line shape from end to end along the left-right direction of the side plate 14a. The side plate 14a is formed with a plurality of (for example, two) joints 15a lines (the same applies to the joints 15b). The joint portions 15a and 15b can be formed, for example, by applying an adhesive in a line shape. Although it does not specifically limit as an adhesive agent, It is suitable to use the reactive hot-melt-adhesive agent which does not reduce adhesive force even if it becomes a high temperature state.

  The side plates 14a and 14b are preferably provided with a printing layer on the surface for displaying a product name, an illustration, a usage precaution, and the like. A printing layer can also be provided on the top plate 13. The printing layer can be formed by the same method as the printing layer (described later) of the stretch film. Moreover, the shape of the top plate 13 and the side plates 14a and 14b can be appropriately changed according to various designs as long as the container 20 can be held. For example, the end portions of the side plates 14a and 14b may be cut into a waveform. Moreover, a finger hook hole into which a fingertip can be inserted may be formed in the top plate 13 and the side plates 14a and 14b, or a handle may be provided separately.

  Here, it illustrates about the suitable stretch film which comprises the cylindrical label 11. FIG.

  A suitable stretch film comprises a label substrate and a printed layer formed on one side of the label substrate. The thickness of the label substrate is preferably 10 to 100 μm, more preferably 15 to 80 μm, and particularly preferably 20 to 50 μm. The thickness of the printing layer is preferably 0.1 to 10 μm. The stretch film may be provided with a layer other than the print layer, for example, a protective layer, as long as the stretch property is not affected.

The stretch film preferably stretches at least 20%, more preferably at least 40%, particularly preferably at least 60% in the circumferential direction of the cylindrical label 11. The residual strain (instantaneous strain) after 60% elongation is preferably 10% or less, and particularly preferably 9% or less. It with respect to the circumferential direction of the cylindrical label 11, it is preferable that tensile stress when allowed to stretch 10% (F10 value) is 6.0 N / mm ² or less, 5.5 N / mm ² or less Is particularly preferred.

  “Tensile stress” is a force acting on a tensile tester when an evaluation sample of a tensile test is pulled at a predetermined speed and stretched. That is, it is a force that opposes extension, and the smaller the tensile stress, the easier the label can be extended and the higher the extensibility. “Residual strain (%)” indicates the degree of plastic deformation of the evaluation sample without returning to the original length after the tensile test. In this specification, the instantaneous strain measured immediately after the load is removed is used as the residual strain. It means that the smaller the instantaneous distortion, the higher the recoverability of the label. That is, the smaller the tensile stress and the residual strain, the better the stretch characteristics.

  The resin constituting the label substrate is not particularly limited as long as good stretch characteristics can be obtained, but is preferably a polyolefin-based resin and particularly preferably a polyethylene-based resin. Polyethylene resins include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), metallocene LLDPE obtained by polymerization using a metallocene catalyst, ethylene-vinyl acetate copolymer, ethylene- (meth) acrylic. Examples include acid ester copolymers and ethylene- (meth) acrylic acid copolymers. These can be used alone or in combination of two or more.

  The label base material is preferably composed of LLDPE as a main component from the viewpoint of stretch characteristics, and particularly preferably has a so-called metallocene LLDPE polymerized using a metallocene catalyst as a main component. The content of LLDPE is preferably 50% by weight or more, more preferably 70% by weight or more, and particularly preferably 90% by weight or more based on the total weight of the resin constituting the label substrate. The label substrate may contain various additives such as a lubricant and an antistatic agent.

  The LLDPE is a copolymer of ethylene and α-olefin. The α-olefin is preferably an α-olefin having 3 to 20 carbon atoms, and an α-olefin having 4 to 8 carbon atoms (for example, 1-butene, 1-pentene, 4-methyl-1-pentene, 1- Particularly preferred are hexene, 1-heptene, 1-octene and the like. The content of the α-olefin component is 1 to 20% by weight, more preferably 2 to 15% by weight, and particularly preferably 5 to 10% by weight with respect to the total weight of the monomer component.

The density of the LLDPE is preferably from 0.880 to 0.930 g / cm ^3, more preferably 0.890~0.925g / cm ^3, in 0.900~0.915g / cm ³ It is particularly preferred. If the density is within this range, good stretch properties can be obtained. The melt flow rate (hereinafter referred to as MFR) of the LLDPE is preferably 1 to 30 g / min, more preferably 1 to 20 g / min, and particularly preferably 1 to 10 g / min. If MFR is within this range, the stretch properties and productivity will be good.

  A commercial item can be used for the LLDPE. As an applicable commercial item, “Umerit (registered trademark) 715FT, 1540F, 0540F” manufactured by Ube Maruzen Polyethylene Co., Ltd. can be exemplified.

  The print layer is, for example, a layer for displaying product names, illustrations, usage precautions, or the like, or a layer for imparting slipperiness to the label substrate. Or you may provide a printing layer in order to conceal the display (for example, barcode display) used for point-of-sale information management (POS: Point Of Sales) provided in each container 20. In this case, at least a part of the bar code display only needs to be concealed, whereby it is possible to prevent the individual containers 20 included in the package 10 from being erroneously detected at the cash register.

  A printing layer is formed by apply | coating printing ink on one surface of a label base material according to a design, for example. Preferably, the printing layer is formed on substantially the entire inner surface of the label substrate excluding the overlapping portion of the film edge in the center seal portion 17. By reducing the film exposed surface on the inner surface of the label base material that is in close contact with the container 20, blocking between the container 20 and the label base material is prevented, and a better container 20 can be extracted. The printing layer may be a so-called white solid printing layer having no characters or patterns. For the formation of the printing layer, solvent-based inks containing desired pigments and dyes, binder resins such as acrylic resins and urethane resins, organic solvents, and various additives (for example, plasticizers, lubricants, waxes, antistatic agents) Alternatively, a printing ink such as a UV-curable ink containing a desired pigment or dye, a photopolymerizable resin such as an acrylic resin, a photopolymerization initiator, and the above-described additives is used. And a printing layer can be formed by performing gravure printing, flexographic printing, letterpress printing, etc. using this printing ink.

  Here, the manufacturing method of the package 10 provided with the said structure is illustrated.

  In the manufacturing process of the package 10, the long body of the cylindrical label 11 and the holding member 12 formed by bending a sheet mainly composed of one sheet of paper to form the top plate 13 and the side plates 14 a and 14 b. Be prepared. And after attaching the predetermined position of each container 20 while cutting the elongate body of the cylindrical label 11, the some container 20 is aligned and the attached cylindrical label 11 and the holding member 12 are joined. Thus, the package 10 is obtained. Hereinafter, each step will be described.

  In the step of preparing the long body of the cylindrical label 11, first, the long body of the label base material is produced. The long body of the label substrate can be produced by, for example, a melt extrusion method. In the melt extrusion method, LLDPE and various additives are put into an extruder and melted, and the molten resin from the extruder is supplied to a T-die to spread it into a smooth thin film, and the thin molten resin is cooled from the die slit. Extruded onto the cast drum and cooled to solidify into a film. For example, the extrusion temperature is preferably about 180 ° C to 240 ° C, and more preferably 200 ° C to 220 ° C. In this way, an elongated body of the label base material mainly composed of LLDPE is produced. In addition, the elongate body of a label base material may be extended | stretched in MD direction and TD direction, for example, in order to improve printing suitability.

  Then, a printing layer is formed in one side of a long body, supplying the long body of a label base material to a printing machine, and conveying continuously in MD direction. As described above, the printing layer can be formed by a gravure printing method or the like. In this way, an elongated body of stretch film in which a printing layer is formed on one surface of the label base material is obtained.

  Subsequently, both edges in the TD direction of the elongated body of the stretch film are overlapped, and the center seal portion 17 is formed using an adhesive, for example. In this way, a long body of the cylindrical label 11 is obtained. At this time, it is preferable to form the center seal portion 17 so that the printed layer is inside the cylindrical label 11. The cylindrical label 11 is formed so that its diameter is smaller than the diameter of the container 20.

  Next, the cylindrical label 11 is attached to a predetermined position of the container 20. In the mounting step, the elongated body of the cylindrical label 11 is supplied to a stretch labeler, cut into individual label sizes, and then mounted on the container 20. The cut cylindrical label 11 is stretched by being pulled in the radial direction, and is fitted on the container 20 being conveyed. When the cylindrical label 11 is attached to the container 20, since the force for extending the label is removed, the label is elastically deformed and attached in close contact with the container 20. Note that the cylindrical label 11 is preferably attached in a state of being stretched in the radial direction by at least about 2%, and can be attached in a state of being stretched by about 75%. In addition, in order to increase the adhesive force between the cylindrical label 11 and the joint portions 15a and 15b, the cylindrical label 11 may be subjected to corona treatment, plasma treatment, flame treatment, or the like.

  In the mounting process, for example, the cylindrical label 11 is mounted so as to cover about the upper 2/3 of the container 20. The cylindrical label 11 is preferably mounted so as to cover the winding portion 24 and extend from the upper end of the side surface portion 23. When this extended portion is joined to the holding member 12, it is pushed by the top plate 13 and bent to the top surface portion 21 side to form a top surface covering portion 16 that covers the periphery of the top surface plate 13.

  Next, the joint portions 15a and 15b are formed on the back surfaces of the side plates 14a and 14b, for example, by applying a reactive hot melt adhesive. Then, a plurality of containers 20 each having a cylindrical label 11 mounted thereon are arranged in a row to form a row 30, and the holding member 12 is covered from above the row 30, and the tubular labels 11 are joined by the joining portions 15 a and 15 b. To do. In this way, the packaging body 10 having a packaging form in which each container 20 is held by the cylindrical label 11 and a plurality of containers 20 are coupled by the holding member 12 via the cylindrical label 11 is obtained.

  As described above, according to the package 10, each cylindrical label 11 coupled by the holding member 12 is attached to each container 20, so that a necessary number of containers 20 are individually pulled out during use. be able to. In the package 10, when one container 20 is used, a packaging form in which a plurality of containers 20 are collected is not disassembled, and the remaining containers 20 do not fall apart, and thus have excellent storage properties.

  Moreover, since the cylindrical label 11 consists of a stretch film, the container 20 is clamp | tightened and hold | maintained strongly with the elasticity. For this reason, omission of the container 20 at the time of sale can be suppressed. Further, since the holding member 12 covers the top surface portion 21 and the side surface portion 23 of the container 20 and the pair of side surface plates 14a and 14b sandwich both sides of the row 30, a stable packaging form can be provided.

  In the packaging body 10, when the container 20 is pulled out, the lower part of the side part 23 that is an exposed part of the container 20 that is not covered with the cylindrical label 11 is grasped and the container 20 is rotated and pulled downward. The container 20 can be easily extracted. And since the cylindrical label 11 is mounted | worn from the periphery of the top | upper surface part 21 to the middle part of the side part 23, covering the level | step-difference part which exists in the boundary of the tightening part 24 and the recessed part 25, container When extracting 20 from the cylindrical label 11, the upper end portion of the cylindrical label 11 is not caught on the winding portion 24, and a smooth extraction operation is possible.

  In addition, as for the level | step-difference part of the coiling | tightening part 24, as mentioned above, the direction where a diameter becomes large and the direction which pulls the container 20 at the time of extraction are reverse. That is, when the upper end of the cylindrical label 11 is below the stepped portion, the upper end (upper edge) of the label is caught by the stepped portion when the container 20 is pulled downward to pull out the container 20 and cannot be removed. End up. Therefore, the label can be smoothly moved with respect to the container 20 by covering the stepped portion and mounting the cylindrical label 11 across the winding fastening portion 24.

The above-described embodiment can be changed in design without departing from the object of the present invention.
Hereinafter, a design change example will be described with reference to FIGS. 5 to 7 (overlapping description will be omitted and differences from the above embodiment will be described).

FIG. 5 is a perspective view of a package 10x which is a modified example.
As shown in FIG. 5, the package 10x packages two connected containers 20 together. The holding member 12x has a top plate 13x and side plates 14ax, 14bx, similar to the package 10, but the length in the left-right direction is shorter than the package 10 because the number of containers 20 to be packaged is small. The cylindrical label 11x has an axial length shorter than that of the cylindrical label 11, and is mounted so as to cover about the upper third of the container 20. Correspondingly, the vertical lengths of the side plates 14ax, 14bx are also shortened. Thus, the size of the package of the present invention can be changed as appropriate according to the number or shape of the items to be packaged.

FIG. 6 is a perspective view of a package 10y which is a modified example.
As shown in FIG. 6, the packaging body 10y packages six connected containers 20 together.

The holding member 12y includes side plates 14ay and 14by arranged to face each other so as to sandwich two rows from the front and back, and a side plate 14cy and side plates 14dy arranged to face each other so as to sandwich the two rows from the front and back. Thus, the package of the present invention can be packaged with a plurality of articles to be packaged arranged in a plurality of rows.

  In the embodiment illustrated in FIG. 6, the joint portion (not shown) between the cylindrical label 11y and the holding member 12y can be formed on the back surfaces of the side plates 14ay and 14by. It is preferable to form also on the face plate 13y, the side face plate 14cy, and the side face plate 14dy. Moreover, the cylindrical labels 11y may be joined to each other.

FIG. 7 is a perspective view of a package 10z which is a modified example.
As illustrated in FIG. 7, the package 10z packages three connected containers 20 together. Each container 20 is in contact with the other two containers 20 and is packaged in a state of being gathered so as to have a substantially triangular shape. The holding member 12z includes a substantially triangular top plate 13z in which each vertex is cut, and three side plates 14az, 14bz, and 14cz extending from the respective sides of the triangle to the bottom surface 22 side. In the form illustrated in FIG. 7, the axial length of the cylindrical label 11z is longer than the vertical length of the side plates 14az, 14bz, 14cz. As described above, the package of the present invention can collectively package a plurality of packages to be packaged so as to exhibit various shapes such as a triangular shape and a hexagonal shape.

In the above description, the holding member 12 is described as covering the top surface portion 21 of the container 20. However, a holding member that covers the bottom surface portion 22 and the side surface portion 23 may be used. In this case, it is preferable that the cylindrical label is attached to the bottom surface portion 22 side of the side surface portion 23.
Moreover, the holding member which consists of a flat sheet, for example, the flat sheet-like holding member which covers the bottom face part 22 may be sufficient. In this case, the cylindrical label 11 wraps around the bottom surface portion 22, and the wrap-around portion and the holding member are joined.
Moreover, the form which covers only the side part of a container may be sufficient as a holding member.
The holding member may be in the form of a holder having a locking portion that can be locked to the stepped portion of the package. For example, a form in which a convex part that is hooked on the stepped part is provided on the back surface of the holding member, or a form in which a cut is formed along the crease line located at the boundary between the top plate and the side plate, and the stepped part is hooked on the cut. It is good.

  Further, when the article to be packaged is a container including a trunk portion and a neck portion having a diameter reduced from the trunk portion, a content extraction opening formed, and a cap attached thereto, the neck portion can be inserted into the top plate 13. It is good also as a form which formed the through-hole. That is, it is a packaging form in which the necks of a plurality of containers protrude from the top plate 13.

  Moreover, the form which does not have a holding member may be sufficient as a package. In this case, the package includes a plurality of cylindrical labels and has a form in which the cylindrical labels are directly joined to each other. That is, in this package, each cylindrical label is mutually joined by the junction part which joins labels directly. As a joining form of the cylindrical labels, a linear shape or a triangular shape can be exemplified as in the above embodiment, and is not particularly limited.

Furthermore, the cylindrical label may be provided with opening means such as perforations as necessary. In particular, when the cylindrical label is applied to the bottom surface portion of the container, it is preferable that a perforation or a cut is provided in the bottom surface covering portion of the label covering the bottom surface portion.
In addition, in order to smoothly remove the container from the cylindrical label, if there is a depression on the side surface of the container that may be caught by the end of the label, the cylindrical label may be attached to cover the depression. Is preferred.
