Description

The present invention relates to a packaging body including a package body packaged in a packaging film body bonded to a base material, and a packaging material used for the packaging body .

A package in which an article to be packaged is packaged appropriately protects the article to be packaged and emphasizes the appearance at a store or the like. Patent Document 1 discloses a package in which a cylindrical film that covers an object to be packaged is joined to a base material. In the package of such a form, when a several package is included in one package, the mode shown in FIG. 26 and FIG. 27 is assumed. The illustrated package X includes a base 91, two cylindrical films 92, two joints 93, and two objects to be packaged 94. For the base material 91, for example, a base paper made of cardboard is used. The tubular film 92 is a heat-shrinkable film that opens in the vertical direction in the figure, and is generally transparent. The joining portion 93 is made of an adhesive or the like, and joins the front surface of the base material 91 and the tubular film 92. The package 94 is an object that can be various types of products. The package X is used to collect two packages 94 together and display them at the store in a state where the purchaser can easily see.

  As described above, the base material 91 that holds the two packages 94 is generally made of cardboard or the like. As the article 94 is heavier, a force to bend acts on the portion of the base material 91 located between the two articles 94. If the two objects to be packaged 94 are arranged close to each other to some extent, the two objects to be packaged 94 come into contact with each other, so that it is avoided that the objects are bent upward in FIG. However, even if the two articles 94 are close to each other, it is inevitable that the base material 91 is bent downward in the drawing as shown in FIG. For this reason, there existed problems, such as the appearance of the package X getting worse and the base material 91 being damaged.

In FIG. 1 and FIG. 2, the packaging film body 2 is hatched for convenience of understanding.

  The base material 1 holds the packaged body 4 via the packaging film body 2 and the joined body 3, and has a main surface 1a. As the base material 1, so-called coated paper having a resin layer provided on its surface or a synthetic resin sheet is used in addition to a common base paper made of so-called non-coated paper such as thick paper, plain paper, and synthetic paper. sell. As these, various sheet materials such as a single layer sheet and a laminated sheet in which two or more of these sheets are laminated and bonded can be used. In the present embodiment, a case where a substantially long rectangular board made of thick paper is used as the base material 1 will be described as an example.

  The packaging film body 2 includes a first packaging part 21 and a second packaging part 22. The 1st packaging part 21 and the 2nd packaging part 22 consist of a cylindrical film made into a different body mutually. The 1st packaging part 21 covers the 1st to-be-packaged part 41 of the to-be-packaged body 4 mentioned later in the contact | adherence state, and the 2nd packaging part 22 covers the 2nd to-be-wrapped part 42 of the to-be-packaged body 4 in the contact | adherence state. Yes. Each of the first packaging part 21 and the second packaging part 22 is a shrinkable film called a so-called shrink film, and is a member for packaging the package body 4 in a close contact state by, for example, thermal shrinkage. In the present embodiment, the first packaging part 21 and the second packaging part 22 are cylindrical bodies that are open at both ends and into which the packaged body 4 can be inserted. In addition, the 1st packaging part 21 and the 2nd packaging part 22 should just have at least one of the upper and lower ends opened, for example. In this embodiment, the both ends opening of the 1st packaging part 21 and the both ends opening of the 2nd packaging part 22 are arrange | positioned so that it may face the same direction.

It is a part engaged so that it may fit in the 2nd non-paved part 42 with a circular cross section through 22. In addition, if the 1st engaging part 56 and the 2nd engaging part 57 correspond to the external shape of the 1st to-be-wrapped part 41 and the 2nd to-be-wrapped part 42, if it is the structure which can maintain an engaging relationship with these, The shape and engagement form are set appropriately. Also according to such an embodiment, the packaged body 4 having the first packaged part 41 and the second packaged part 42 can be appropriately packaged. Further, the reinforcing member 5 of the present embodiment does not need to have an adhesive surface.

  Furthermore, as a modification of the auxiliary member 5 of the present invention, a cylindrical film or the like that collectively covers the base material 1, the packaging film body 2, and the package body 4 may be used. Further, a part of the base material 1 may be extended, and this extended part may be used as the reinforcing member 5.

Moreover, FIGS. 17-19 has shown the manufacturing method of the package using the packaging material B6. 17 is a perspective view illustrating a state in which the package body 4 is accommodated in the packaging material B6, FIG. 18 is a cross-sectional view taken along line XIV-XIV in FIG. 17, and FIG. It is sectional drawing which follows a XV line. In FIG. 17 and FIG. 20, for the sake of easy understanding, the packaging film material 2A is treated as a transmissive body, and it is described on the assumption that the elements behind or the contained elements can be visually recognized.

  The base material 1 is made of the above-described material, and in the present embodiment, a case where a substantially long rectangular base material made of cardboard is used as the base material 1 will be described as an example. The base material 1 of the present embodiment is formed with a through-hole for hanging on a hook at a store.

  The packaging film material 2A is a shrinkable film referred to as a so-called shrink film, and is a member that packages the package body 4 in a close contact state by, for example, thermal shrinkage. In the present embodiment, the packaging film material 2A is a cylindrical body that is open at both ends and into which the packaged body 4 can be inserted. In addition, the packaging film material 2A should just be what has at least one of the upper and lower ends opened, for example. The packaging film material 2A is made of the same material as the packaging film body 2 described above.

  In the present embodiment, the packaging film material 2A is a heat-shrinkable uniaxially stretched film. The packaging film material 2A has a substantially long rectangular shape whose longitudinal direction coincides with the base material 1 in this embodiment, and has two end edges 2Aa at both ends in the longitudinal direction. The end edge 2 </ b> Aa is an opening for inserting the package body 4. The main stretching direction S of the packaging film material 2A is perpendicular to the direction in which the two end edges 2Aa are separated from each other, and is along the width direction of the packaging film material 2A. The packaging film material 2A has a property that when heated, the thermal shrinkage along the main stretching direction S is significantly larger than the thermal shrinkage along other directions.

  The packaging film material 2A has a first packaging part 21A, a second packaging part 22A, and a cutting scheduled part 23. As shown in FIGS. 14, 2, 17 and 19, the first packaging part 21 </ b> A is a part for packaging the first packaged part 41 of the packaged body 4. The second packaging part 22 </ b> A is a part for packaging the second packaged part 42 of the packaged body 4. In addition, the structure which has parts other than the 1st packaging part 21A and the 2nd packaging part 22A may be sufficient as 2A of packaging film materials.

  The scheduled cutting part 23 partitions at least a part of the first packaging part 21A and the second packaging part 22A, and in the present embodiment, all of the first packaging part 21A and the second packaging part 22A. Separate each other. That is, the scheduled cutting part 23 is provided over the entire circumference of the packaging film material 2A along the main stretching direction S, and bisects the packaging film material 2A into the first packaging part 21A and the second packaging part 22A. . The position of the scheduled cutting part 23 is away from the center in the longitudinal direction of the packaging film material 2A, and is located closer to one end edge 2Aa. Thereby, 22 A of 2nd packaging parts are small with respect to 21 A of 1st packaging parts.

  Moreover, the cutting scheduled part 23 is a part cut | disconnected when the packaging film material 2A heat shrinks in the state which accommodated the to-be-packaged body 4. FIG. As an example of the scheduled cutting part 23 that can be cut by thermal contraction, for example, one formed by a perforation line can be cited. The perforation line has a configuration in which a plurality of penetrating portions and a plurality of non-penetrating portions are alternately arranged. The ratio of the length of the penetrating part and the length of the non-penetrating part is not particularly limited, but when it is intended to cut smoothly during heat shrinkage, the ratio of the length of the penetrating part and the length of the non-penetrating part is 1: 1 to 7: 1 is preferable, and 1.5: 1 to 5: 1 is more preferable. However, the planned cutting portion 23 is not limited to the perforation line, and can be cut by thermal contraction, for example, a configuration in which a part of the packaging film material 2A is locally thinned or a configuration in which it is locally bent. It only has to be done.

  The joined body 3 joins the base material 1 and the packaging film material 2 </ b> A, and has a first joint portion 31 and a second joint portion 32. As shown in FIG. 14, the first joining portion 31 overlaps the first packaging portion 21 </ b> A of the packaging film material 2 </ b> A in the thickness direction view of the base material 1, that is, in plan view, and the first packaging portion 21 </ b> A is used as the base material. 1 main surface 1a. The second joint portion 32 overlaps with the second packaging portion 22A in plan view, and joins the second packaging portion 22A to the main surface 1a of the base 1. In the present embodiment, the first joint portion 31 and the second joint portion 32 are separate from each other. The direction in which the first joint portion 31 and the second joint portion 32 are separated from each other is a direction intersecting the main stretching direction S, more specifically, a direction perpendicular to the main stretching direction S. Along the longitudinal direction. As shown in FIG. 14, the first joint portion 31 and the second joint portion 32 are separated from each other with the planned cutting portion 23 interposed therebetween. That is, the joined body 3 is provided at a position avoiding the planned cutting portion 23 in plan view. Further, the second joint portion 32 is made smaller than the first joint portion 31 in correspondence with the magnitude relationship between the first packaging portion 21A and the second packaging portion 22A of the packaging film material 2A. Although the 1st junction part 31 and the 2nd junction part 32 are made into the rectangular shape, this is an example and the shape of the 1st junction part 31 and the 2nd junction part 32 is set variously.

  In addition, the joined body 3 has the 1st junction part 31 which fulfill | performs the function which joins 21 A of 1st packaging parts to the base material 1, and the 2nd junction part 32 which fulfill | performs the function which joins 22 A of 2nd packaging parts to the base material 1. As long as the configuration is such that the packaging film material 2A is joined to the base material 1, the first joining portion 31 and the second joining portion 32 are not limited to separate structures. The whole may be integrally formed including the second joint portion 32. Furthermore, the joined body 3 may have a configuration having a part other than the first joined portion 31 and the second joined portion 32 apart from these. What is necessary is just to use the material mentioned above for the conjugate | zygote 3 suitably.

  The reinforcing member 5 of the present embodiment has a configuration similar to that of the reinforcing member 5 in the package A2 described above, and includes a first joint portion 51, a second joint portion 52, and a non-joint portion 53. The first joining portion 51 is joined to the first packaging portion 21A of the packaging film material 2A, and the second joining portion 52 is joined to the second packaging portion 22A. Although the non-joining part 53 can be in contact with the packaging film material 2A, it is not joined to the packaging film material 2A. Moreover, the non-joining part 53 has overlapped with the scheduled cutting part 23 of 2 A of packaging film materials in planar view. The reinforcing member 5 may be made of the above-described material as appropriate.

  Next, an example of a method for manufacturing the package A6 using the packaging material B6 will be described below. In addition, in the following description, although the case where the packaging body A6 mentioned later is manufactured using one packaging material B6 is demonstrated to an example, the packaging material B6 which connected the several packaging material B6 integrally, for example is demonstrated. You may manufacture several package A6 collectively using an aggregate | assembly.

  FIGS. 17-19 has shown 1 process of the manufacturing process of package A6 using packaging material B6. In these figures, the packaging body 4 is accommodated in the packaging film material 2A of the packaging material B6. In the present embodiment, the packaged body 4 includes a first packaged part 41 and a second packaged part 42 that are separated from each other. The first packaged part 41 is inserted into the packaging film material 2A from either edge 2Aa, and the first packaged part 41 is accommodated by the first packaged part 21A. Moreover, the 2nd to-be-packaged part 42 is inserted in 2 A of packaging film materials from either edge 2Aa, and the 2nd to-be-packaged part 42 is accommodated by 22 A of 2nd packaging parts.

  In addition, if the to-be-packaged body 4 is the structure which has the 1st to-be-packaged part 41 accommodated in 21 A of 1st packaging parts of the packaging film material 2A, and the 2nd to-be-packaged part 42 accommodated in 22 A of 2nd packaging parts. Well, it is not limited to the structure by which the 1st to-be-packaged part 41 and the 2nd to-be-packaged part 42 were mutually separated. For example, the packaged body 4 may have a configuration in which the first packaged part 41 and the second packaged part 42 are connected to each other. Further, the packaged body 4 may have a configuration in which a part other than the first packaged part 41 and the second packaged part 42 is separated from these.

  In the present embodiment, the first packaged part 41 is composed of a plurality of dry batteries 41a and a plurality of preliminary packaging films 41b, and the second packaged part 42 is composed of a plurality of dry batteries 42a and a preliminary packaging film 42b. Will be described. For convenience of understanding, the preliminary packaging film 41b and the preliminary packaging film 42b are omitted in FIGS. The dry battery 41a and the dry battery 42a are typically substantially AA-size batteries or AAA batteries. The preliminary packaging film 41b and the preliminary packaging film 42b are used to wrap a predetermined number of dry batteries 41a and the preliminary packaging film 41b as an integral product in advance before inserting the package 4 into the packaging material B6.

  In the present embodiment, two dry batteries 41a are packaged as one set by one preliminary packaging film 41b, and two dry batteries 42a are packaged as one set in one preliminary packaging film 42b. And the 1st to-be-packaged part 41 consists of 4 sets (8 pieces) of dry batteries 41a and 4 preliminary packaging films 41b, and the 2nd to-be-wrapped part 42 consists of 1 set (2 pieces) of dry batteries 42a and one It consists of a preliminary packaging film 42b. By setting it as such a form, when inserting the 1st to-be-wrapped part 41 and the 2nd to-be-wrapped part 42 in 2A of packaging film materials, and after that, the dry battery 41a and the dry battery 42a may roll unintentionally alone. The first packaged part 41 and the second packaged part 42 can be easily and accurately arranged at desired positions.

  Next, the packaging film material 2A is thermally contracted using, for example, a steam tunnel facility or a hot-air tunnel facility set at a predetermined temperature. Thereby, as shown in FIGS. 20 to 22, the heat-shrinkable packaging film material 2 </ b> A becomes the packaging film body 2. In addition, in FIG. 22, 2A of packaging film materials before heat-shrinking are shown with the imaginary line.

  As shown in FIG. 22, when the packaging film material 2 </ b> A is thermally shrunk, it is shrunk mainly along the main stretching direction S described above. Moreover, it is common to show some shrinkage also in the longitudinal direction perpendicular to the main stretching direction S. In this case, the packaging film material 2A slightly shrinks in the longitudinal direction as well. Here, the first packaging portion 21 </ b> A of the packaging film material 2 </ b> A is joined to the base material 1 by the first joint portion 31, and the second packaging portion 22 </ b> A is joined to the base material 1 by the second joint portion 32. . Accordingly, the first packaging portion 21A exhibits a behavior of contracting with the first joint portion 31 as an approximate center, and the second packaging portion 22A exhibits a behavior of contracting with the second joint portion 32 as an approximate center. For this reason, a force that pulls in the longitudinal direction of the packaging film material 2A (a direction perpendicular to the main stretching direction S) acts on the planned cutting portion 23 extending along the main stretching direction S, whereby the planned cutting portion 23 is cut. Let As a result, the part that was the first packaging part 21A of the packaging film material 2A becomes the first packaging part 21, and the part that was the second packaging part 22A becomes the second packaging part 22. The 1st packaging part 21 wraps the 1st to-be-wrapped part 41 in a contact | adherence state, and the 2nd packaging part 22 wraps the 2nd to-be-wrapped part 42 in a contact | adherence state. That is, the packaging film body 2 formed by the thermal contraction of the packaging film material 2 </ b> A is configured as a first packaging portion 21 and a second packaging portion 22 that are separated from each other. Further, the reinforcing member 5 is not joined to the packaging film material 2A, although the first joining part 51 is joined to the first packaging part 21A and the second joining part 52 is joined to the second packaging part 22A. A junction 53 is provided. By providing the non-joining portion 53 at a position overlapping the planned cutting portion 23, the reinforcing member 5 does not have a risk of preventing this cutting when the packaging film material 2A is cut at the planned cutting portion 23.

  Further, one of the two end edges 2 </ b> Aa of the packaging film material 2 </ b> A is an end edge 21 a of the first packaging part 21, and the other is an end edge 22 a of the second packaging part 22. One of the two edges that appear when the planned cutting part 23 cuts becomes the edge 21 b of the first packaging part 21, and the other becomes the edge 22 b of the second packaging part 22. When the edge 2Aa in the packaging film material 2A is a smooth linear shape having no intentional uneven shape, the edge 21a and the end edge 22a become a smooth linear shape having no remarkable uneven shape, Depending on the degree of contraction, for example, it exhibits an elliptical shape as a whole. On the other hand, the end edge 21b and the end edge 22b that appear when the planned cutting portion 23 formed by the perforation line is cut have slight irregularities as shown in FIG. The overall shape of the end edge 21b and the end edge 22b has, for example, an elliptical shape depending on the degree of contraction, similar to the end edge 21a and the end edge 22a.

  By passing through the above process, the package A6 shown in FIGS. 20-22 is obtained. The packaging body A6 includes a base material 1, a packaging film body 2, a joined body 3, a packaged body 4, and a reinforcing member 5. The packaging film body 2 includes a first packaging part 21 and a second packaging part 22 that are separate from each other as described above. The joined body 3 includes a first joined portion 31 and a second joined portion 32, and the first joined portion 31 joins the first packaging portion 21 of the packaging film body 2 to the main surface 1a of the base material 1 and is second. The joining part 32 joins the second packaging part 22 to the main surface 1 a of the base material 1. The packaged body 4 includes a first packaged part 41 and a second packaged part 42 that are separate from each other. The first packaged portion 41 is wrapped in close contact with the first packaged portion 21, and the second packaged portion 42 is wrapped in close contact with the second packaged portion 22. The reinforcing member 5 has a first joint portion 51, a second joint portion 52, and a non-joint portion 53. The first joining part 51 is joined to the first packaging part 21, and the second joining part 52 is joined to the second packaging part 22. Thereby, the reinforcement member 5 has connected the 1st to-be-packaged parts 41 and 42. FIG.

  Even in such an embodiment, the packaged body 4 including the first packaged portion 41 and the second packaged portion 42 can be appropriately packaged. Moreover, the cutting | disconnection scheduled part 23 provided in 2A of packaging film materials of packaging material B6 is cut | disconnected in a shrinkage | contraction process, The 1st packaging part 21A is made independent according to the shape and size of the 1st to-be-packaged part 41. The second packaging part 22A can be contracted independently according to the shape and size of the second packaged part 42. Therefore, the to-be-packaged body 4 of a more various form can be packaged appropriately.

  The 1st junction part 31 and the 2nd junction part 32 which comprise the conjugate | zygote 3 are set as the separate body mutually spaced apart. For this reason, the first packaging portion 21 </ b> A joined to the base material 1 by the first joint portion 31 contracts around the first joint portion 31. If this 1st junction part 31 has overlapped with the 1st to-be-packaged part 41 in planar view, 21 A of 1st packaging parts will shrink | contract with a good balance centering on the 1st to-be-packaged part 41. Similarly, the second packaging portion 22A also shrinks in a well-balanced manner with the second packaged portion 42 as the center. Therefore, the first packaged part 41 and the second packaged part 42 can be appropriately packaged by the first packaging part 21 and the second packaging part 22. Moreover, the 1st junction part 31 and the 2nd junction part 32 are spaced apart in the direction orthogonal to the main extending | stretching direction S, and the cutting plan part 23 is provided because the cutting plan part 23 is located in the meantime. The part of the packaging film material 2 </ b> A can be thermally contracted without being obstructed by the joined body 3, and the cutting scheduled portion 23 can be cut well. Moreover, after the cutting | disconnection scheduled part 23 is cut | disconnected, 21 A of 1st packaging parts and 22 A of 2nd packaging parts can be shrunk stably with sufficient balance.

  23 and 24 show a package based on the seventh embodiment of the present invention. The package A7 of this embodiment is called a so-called skin pack package, and the basic packaging form is different from the above-described packages A1 to A4. The package A7 includes a base material 1, a packaging film body 20, a packaged body 4, and a reinforcing member 5.

The joining portion 27 is a portion of the packaging film body 20 other than the first packaging portion 25 and the second packaging portion 26, and is joined to the main surface 1 a of the base material 1.

  As the packaging film body 20 of this embodiment, a synthetic resin film having a single layer configuration or one or two or more multilayer configurations is used. In addition, a known film having various functions such as gas barrier properties and light shielding properties can be used as necessary. The thickness of the packaging film body 20 is usually 30 μm to 300 μm, preferably 60 μm to 200 μm. FIG. 23 shows a state in which the transparent packaging film body 20 covers the base material 1 and the package body 4, and the base material 1 and the package body 4 are visible through the packaging film body 20.

  In the present embodiment, the packaging film body 20 is preferably a multilayer film having at least two layers of resins having different melting points. Specifically, for example, a resin having a high melting point (that is, a resin having heat resistance and stronger than a resin having a low melting point) is used as an intermediate layer, and a resin having a lower melting point than the resin in the intermediate layer is used as a front and back layer. Or a laminated part in which a plurality of high-melting resins and low-melting resins are alternately laminated (usually a composite of high-melting resin and low-melting resin laminated one by one). And a film having 3 or more layer portions). By laminating a resin having higher heat resistance than a low melting point resin that contributes to adhesion to the base material 1, while maintaining a certain degree of stretchability as a characteristic of the skin pack film with the low melting point resin, The strength of the packaging film body 20 can be improved with the resin. Moreover, the strength of the film can be improved by the resin having a high melting point while the adhesiveness between the base material 1 and the packaging film body 20 is strengthened by providing the resin having a low melting point.

The adhesive layer 30 may be provided in a solid shape or may be provided intermittently. Moreover, this adhesive layer 30 may be provided on the back surface of the packaging film body 20. When the adhesive layer 30 is provided on the back surface of the packaging film body 20, there is no need to provide the adhesive layer 30 on the base material 1 side. Although the thickness of the adhesive bond layer 30 is not specifically limited, For example, they are 10 micrometers-30 micrometers. In the present embodiment, a case where the adhesive layer 30 is provided on one side of the base material 1 will be described as an example.

  The adhesive that forms the adhesive layer 30 is not particularly limited, and may be a commonly known heat-sensitive adhesive or pressure-sensitive adhesive, or pressure-sensitive adhesive or pressure-sensitive adhesive, but exhibits adhesiveness when not required. Therefore, it is preferable to use a heat-sensitive adhesive or pressure-sensitive adhesive (hereinafter collectively referred to as “heat-sensitive adhesive or the like”).

  The heat-sensitive adhesive is an adhesive that is solidified at room temperature and is activated by heating to exhibit adhesiveness, and is solidified by cooling to adhere between members.

Examples of the delayed tack type include an ethylene-vinyl acetate copolymer, a vinyl acetate-acrylic acid ester copolymer, and a base resin such as a synthetic rubber in which a tackifier and a solid plasticizer are blended. .

  In the emulsion type or solvent type, for example, a solution in which a heat-adhesive resin such as an ethylene-vinyl acetate copolymer and a tackifier are dissolved or dispersed in water or an organic solvent is applied by printing such as gravure coating. It can be processed and used after drying after coating. These also do not show adhesiveness after drying, but show adhesiveness by heating.

  The hot melt type is one that is heated and melted by a hot melt coater, an extrusion laminator or the like. Examples of this include an ethylene resin such as an ethylene-vinyl acetate copolymer and an ethylene acrylic acid copolymer, and a base resin such as a styrene-butadiene block copolymer that is blended with an additive such as a tackifier.

By using an adhesive having such a softening point, when the packaging film body 20 is heated to soften, the heat of the adhesive layer 30 can be activated by the heat. The softening point can be measured according to JIS K 6863.

  The package body 4 is interposed between the base material 1 and the packaging film body 20 and is supported by the main surface 1a of the base material 1 and is fixed to the main surface 1a of the base material 1 by the packaging film body 20. And protection is made. In the present embodiment, a base body 1 supports a package body 4 including a first packaged portion 41 having a rectangular shape in plan view and a second packaged portion 42 having a circular shape in plan view. In addition, the shape of the 1st to-be-wrapped part 41 and the 2nd to-be-wrapped part 42 is not limited to what was illustrated, but is set as various shapes.

  The reinforcing member 5 has a first joint portion 51 and a second joint portion 52. The first joining portion 51 is joined to the first packaging portion 25 of the packaging film body 20, and the second joining portion 52 is joined to the second packaging portion 26 of the packaging film body 20. Although the illustrated reinforcing member 5 is shown as an example having a non-joining portion 53, the reinforcing member 5 having an entire non-adhesive surface that can form the non-joining portion 53 as an adhesive surface. It may be. Furthermore, the reinforcing member 5 in the packaging bodies A1 to A6 described above may be appropriately employed.

  If the manufacturing method of package A7 is illustrated, the cardboard material which can form the several base material 1 will be prepared first. In this cardboard material, an area for mounting a plurality of packages 4 corresponding to the plurality of packages A7 is secured. Next, a plurality of packages 4 are placed on the upper surface of the cardboard material. And the film material used as the some packaging film body 20 is put on the said cardboard material and the some package body 4. At this time, the film material is heated to an appropriate temperature in order to promote an appropriate deformation and to exert an adhesive force with the cardboard material.

  Next, suction from the lower surface of the cardboard material, that is, a deaeration process is performed. Thereby, the air between the cardboard material and the film material is degassed through the cardboard material. Then, the film material is in close contact with the cardboard material and the plurality of packages 4 while being stretched. Thereafter, the cardboard material and the film material are cut into a plurality of pieces so that each piece includes the packaged body 4 including the first packaged portion 41 and the second packaged portion 42. To do. Prior to or after this cutting, the first joint 51 of the reinforcing member 5 is joined to the first packaging part 25 and the second joining part 52 is joined to the second packaging part 26. Thereby, several package A7 is obtained.

  Even in such an embodiment, the packaged body 4 including the first packaged portion 41 and the second packaged portion 42 can be appropriately packaged. Moreover, it is possible to package the 1st to-be-packaged part 41 and the 2nd to-be-packaged part 42 collectively by the packaging film body 20 which consists of one film material. For this reason, in the manufacturing process of package A7, the effort which inserts the 1st to-be-packaged part 41 and the 2nd to-be-packaged part 42 into a cylindrical film separately can be saved.

  FIG. 25 shows a modification of the package A7. In the present modification, the package body 4 includes a connecting portion 43 in addition to the first package portion 41 and the second package portion 42. The connecting part 43 is a member that connects the first packaged part 41 and the second packaged part 42. However, the connecting portion 43 does not have a rigidity that can support the first packaged portion 41 and the second packaged portion 42 only by this, and is typically a band made of a relatively soft material or It is a string. In particular, in this embodiment, the connection part 43 is not arrange | positioned linearly between the 1st to-be-packaged part 41 and the 2nd to-be-packaged part 42, but is arrange | positioned so that it may detour. The connecting portion 43 is covered with a portion other than the first packaging portion 25 and the second packaging portion 26 in the packaging film body 20. As can be understood from this modification, in the present invention, the packaged body 4 is not limited to the first packaged part 41 and the second packaged part 42 that are completely separated from each other, and The structure by which the separated 1st to-be-packaged part 41 and the 2nd to-be-packaged part 42 were connected by the connection part 43 may be sufficient. Such a packaged body 4 may be appropriately applied to the above-described packages A1 to A6.

  The package according to the present invention is not limited to the above-described embodiment. The specific configuration of the package according to the present invention can be varied in design in various ways.
