Description

Technical Field

[0001] The utility model relates to a glass tube assembly package including a plurality of glass tube assemblies formed by bundling a plurality of glass tubes with a bundling film and a packing film for covering and packing the plurality of glass tube assemblies. Background Art

[0002] Conventionally, glass tubes used in, for example, medical ampoules and fluorescent tubes for lighting have been assembled by assembling multiple glass tubes of the same length in multiple rows and stages and then packaging them in a bundle using a shrink film or the like.

[0003] After the glass tube assembly thus packaged is placed on a base (pallet) for logistics, the periphery of the glass tube package is covered with a packaging film such as a shrink film, and the glass tube assembly is packaged together into a single glass tube assembly package while maintaining a stable package shape (see, for example, Patent Document 1).

[0007] Issues to be solved by utility models

[0008] When a glass tube assembly package having such a packaging configuration is transported by a truck, for example, the truck may sway, causing the glass tube assembly package placed on the cargo bed to sway as well. When the glass tube assembly package sways, the glass tube assemblies covered by the packaging film may sway, causing adjacent glass tube assemblies to come into contact with each other, potentially damaging the glass tubes.

[0009] The present invention has been made in view of the above-mentioned current problems, and aims to provide a glass tube assembly package that can suppress the swinging of a glass tube assembly group covered with a packaging film, thereby suppressing contact between the glass tube assemblies and preventing damage to the glass tubes due to contact between the glass tube assemblies.

[0010] Solutions to Problems

[0011] The problems to be solved by the present invention are as described above, and the means for solving the problems will be described below.

[0012] Specifically, a glass tube assembly package according to a first aspect of the present invention includes: a plurality of glass tube assemblies formed by bundling the plurality of glass tubes with a bundling film; and a wrapping film covering and bundling the plurality of glass tube assemblies, wherein a thickness t1 of the wrapping film is 150 μm or greater.

[0013] As described above, in the present invention, the thickness of the packaging film is configured to be relatively thick, and the loading state (or packaging state) of the glass tube package is more firmly maintained by the packaging film.

[0014] Therefore, even if the glass tube assembly package sways during transportation, for example, the glass tube assembly group covered by the packaging film can be prevented from swaying, thereby preventing the glass tube assemblies from contacting each other. Therefore, even if the glass tube assembly package sways, damage to the glass tubes due to contact between the glass tube assemblies can be prevented.

[0015] Furthermore, a glass tube assembly package according to a second aspect of the present invention is characterized in that, in addition to the first aspect, a thickness t2 of the bundling film is 150 μm or less.

[0016] As described above, in the present invention, the thickness of the bundling film is made relatively thin, allowing the thermal contraction of the bundling film during heating to occur in a relatively short period of time. Consequently, the process of bundling a plurality of glass tubes assembled in multiple rows and stages using the bundling film can be performed efficiently, thereby improving the workability of the glass tube assembly packaging operation.

[0017] Furthermore, the glass tube assembly package according to the third aspect of the present invention is characterized in that the thickness t1 of the packaging film and the thickness t2 of the bundling film satisfy the relationship t1 / t2≥1.

[0018] Thus, in the present invention, the wrapping film is constructed to be relatively thick, allowing the wrapping film to more securely maintain the loaded configuration (or packaged configuration) of the glass tube assembly. Therefore, even if the glass tube assembly package sways during transport, for example, the glass tube assembly group covered by the wrapping film can be prevented from swaying, thereby preventing contact between the glass tube assemblies. Consequently, even if the glass tube assembly package sways, damage to the glass tubes due to contact between the glass tube assemblies can be prevented.

[0019] Furthermore, in the present invention, the thickness of the bundling film is relatively thin, allowing the film to shrink during heating in a relatively short period of time. Consequently, the process of bundling a plurality of glass tubes assembled in multiple rows and stages using the bundling film can be performed efficiently, thereby improving the workability of the glass tube assembly packaging operation.

[0020] Furthermore, the glass tube assembly package according to the fourth aspect of the present invention is characterized in that the thickness t1 of the packaging film and the thickness t2 of the bundling film satisfy the relationship t1 / t2≥1.2.

[0021] Thus, in the present invention, the wrapping film is constructed to be relatively thick, allowing the wrapping film to more securely maintain the loaded configuration (or packaged configuration) of the glass tube assembly. Therefore, even if the glass tube assembly package sways during transport, for example, the glass tube assembly group covered by the wrapping film can be prevented from swaying, further reducing contact between the glass tube assemblies. Consequently, even if the glass tube assembly package sways, damage to the glass tubes due to contact between the glass tube assemblies can be further prevented.

[0022] Furthermore, in the present invention, the thickness of the bundling film is relatively thin, allowing the film to shrink during heating in a relatively short period of time. Consequently, the process of bundling multiple glass tubes in multiple rows and stages using the bundling film can be performed efficiently, further improving the workability of the glass tube assembly packaging process.

[0023] Utility model effect

[0024] The following effects are achieved as the effects of the present invention.

[0043] Next, use Figures 1 to 5 An embodiment of the present invention will be described.

[0044] It should be noted that in the following description, for convenience, Figures 1 to 4 The directions of the arrows shown in the figure define the front-back direction, the left-right direction, and the up-down direction of the glass plate packaging pallet.

[0045] [Overall Structure of Glass Tube Assembly Package 1]

[0046] First, use Figures 1 to 4 The overall structure of the glass tube assembly package 1 embodying the present invention will be described.

[0047] The glass tube assembly package 1 mainly includes a base 2 , a glass tube assembly 3 , an inner cushion member 4 , a packaging film 5 , and side protection members 6 .

[0048] The base 2 serves as the base of the glass tube assembly package 1 .

[0049] The base 2 is made of an appropriately selected optimal material such as wood, metal, synthetic resin, or FRP (reinforced plastic), and is configured as a pallet (loading platform) into which the transport claws of a forklift can be inserted.

[0050] It should be noted that the structure of the base 2 is not limited to the present embodiment. For example, any structure may be used as long as it has a sufficient area for placing multiple glass tube assemblies 3, 3, ... in multiple rows and multiple stages and has the rigidity to stably support these glass tube assemblies 3, 3, ....

[0051] Next, the glass tube assembly 3 will be described.

[0052] The glass tube assembly 3 is composed of a plurality of glass tubes G assembled by a bundling film F, wrapping paper, or the like.

[0053] Here, the glass tube G is a glass member used in, for example, medical ampoules, fluorescent tubes for lighting, and the like, and is formed in a long hollow cylindrical shape.

[0054] Multiple glass tubes G, G... have equal lengths and are assembled in multiple rows and stages. They are then wrapped with wrapping paper (not shown) or the like. Thereafter, they are wrapped with a bundling film F and heated in a heating device (not shown). The bundling film F shrinks and the multiple glass tubes G, G... are bundled.

[0055] The bundling film F covers both ends in the longitudinal direction of the glass tubes G, G, ... arranged in multiple rows and multiple stages, and shrinks by being heated to bundle the glass tubes G, G, ... arranged in multiple rows and multiple stages.

[0056] In this manner, the glass tube assembly 3 is formed into a long rectangular parallelepiped shape, and is firmly maintained in its packaged form by the bundling film F, the wrapping paper, and the like.

[0057] The glass tubes G, G, . . . assembled in multiple rows and stages are bundled with a bundling film F to form a glass tube assembly 3 .

[0058] It should be noted that in this embodiment, the packaging form of multiple glass tubes G, G... is maintained by using a bundling film F, wrapping paper, etc., but this is not limited to this. For example, the packaging form of multiple glass tubes can also be maintained by using only a bundling film F without using wrapping paper.

[0059] In this embodiment, the bundling film F covers both ends in the longitudinal direction of the glass tubes G, G... arranged in multiple rows and multiple stages, thereby bundling the glass tubes G, G... arranged in multiple rows and multiple stages. However, the present invention is not limited to this embodiment. For example, the bundling film F may cover one end in the longitudinal direction of the glass tubes G, G... arranged in multiple rows and multiple stages, a longitudinal portion of the glass tubes G, G..., or the entire glass tubes G, G... arranged in multiple rows and multiple stages, thereby bundling the glass tubes G, G... arranged in multiple rows and multiple stages.

[0060] The bundle film F is formed of a shrink film.

[0061] It should be noted that the material of the bundling film F is not particularly limited, and may be any material such as PVC (polyvinyl chloride), PP (polypropylene), or PE (polyethylene).

[0062] The bundling film F is not limited to the shrink film shown in this embodiment, and may be formed of, for example, a polyethylene stretch film as long as it can be packaged in a sealed state while firmly maintaining the packaged shape of the glass tube assembly 3 .

[0063] A predetermined number (e.g., four in this embodiment) of the glass tube assemblies 3, 3, ... constructed in this manner are prepared at each stage on the base 2 and arranged in a horizontal direction (a direction perpendicular to the longitudinal direction in a plan view) with the longitudinal direction as the front-back direction.

[0064] Then, the glass tube assemblies 3 , 3 . . . (hereinafter referred to as “glass tube assembly group 30 ” as appropriate) arranged in multiple rows in each stage are placed on the base 2 via the backing member 4 .

[0065] That is, on the base 2 , a plurality of glass tube assembly groups 30 , 30 . . . are stacked in multiple stages (for example, eight stages in this embodiment) with the inner cushion members 4 interposed therebetween to form a rectangular parallelepiped glass tube package 30G.

[0066] It should be noted that, in this embodiment, a plurality of glass tube assemblies 3 , 3 . . . are placed on the base 2 , but the present invention is not limited thereto. For example, a single glass tube assembly 3 may be placed on the base 2 .

[0067] However, when there is only one glass tube assembly 3 , the glass tube assembly 3 becomes the glass tube package 30G.

[0068] Next, the inner pad member 4 will be described.

[0069] The inner cushion member 4 is a member that functions as a cushioning material.

[0070] The inner cushion member 4 is formed of, for example, a rectangular sheet of corrugated paper and is disposed between the plurality of glass tube assembly groups 30 stacked on the base 2. The inner cushion member 4 is placed so as to cover the entire upper surface of the glass tube assembly group 30 in each stage.

[0071] Here, the longitudinal dimension of the inner cushion member 4 (the dimension of the inner cushion member 4 in the front-to-back direction) is preferably set to be slightly shorter than the longitudinal dimension (the front-to-back direction) of the glass tube assembly 30 in order to avoid interference with the side protectors 6 arranged at the corners (corner portions 31A described later) of the glass tube packages 30G stacked on the base 2.

[0072] On the other hand, the lateral dimension of the inner cushion member 4 (the dimension of the inner cushion member 4 in the left-right direction) is set to be slightly longer than the dimension of the glass tube assembly group 30 in the width direction (the left-right direction).

[0073] The inner cushion member 4 is disposed between vertically adjacent glass tube assembly groups 30 and on the upper surface of the uppermost glass tube assembly group 30 , with both left and right ends extending to both sides in the width direction of the glass tube assembly group 30 .

[0074] In addition, both left and right end portions of the inner cushion member 4 extending from the glass tube assembly 30 are bent downward along the side surfaces of the glass tube assembly 30 .

[0075] As a result, the inner cushion member 4 is a plate-shaped member that is open downward and has a shape of "コ" in Japanese katakana when viewed from the front, and is formed by a top plate portion 4a formed in a shape substantially identical to the upper surface of the glass tube assembly 30 and a pair of (at the bottom) inner cushion members extending downward along the mutually opposing edges of the top plate portion 4a. Figure 1 Since it is a three-dimensional diagram, only one piece is recorded) The ear pieces 4b and 4b are composed.

[0076] Thus, the ear pieces 4 b of the inner cushion member 4 effectively prevent positional shift in the width direction of the plurality of glass tube assemblies 3 , 3 . . . arranged in parallel in each stage and the collapse of the cargo.

[0077] Next, the packaging film 5 will be described.

[0078] The packaging film 5 is a member that covers and packages the glass tube package 30G (i.e., the glass tube assembly 3) placed on the base 2 together with the base 2, and is used to firmly hold the glass tube package 30G relative to the base 2 while maintaining the loaded form (or packaged form).

[0079] In the present embodiment, the packaging film 5 is formed of, for example, a shrink film.

[0080] It should be noted that the material of the packaging film 5 is not particularly limited, and may be any material such as PVC (polyvinyl chloride), PP (polypropylene), or PE (polyethylene).

[0081] The packaging film 5 is not limited to the shrink film shown in this embodiment, and may be formed of, for example, a polyethylene stretch film as long as it can package the glass tube package 30G placed on the base 2 in a sealed state.

[0082] The packing film 5 is composed of a first packing film 51 formed of a sheet-shaped shrink film and a second packing film 52 formed of a bag-shaped shrink film (refer to the two members 51 and 52 for details). Figure 3 、 Figure 4 ) and so on.

[0083] Then, as will be described later, the first packaging film 51 is laid between the base 2 and the lowermost glass tube assembly group 30 (more specifically, the first glass tube assembly group 30A) placed on the base 2 .

[0084] Here, the first packaging film 51 is formed larger than the upper surface of the base 2 and extends in the front-rear and left-right directions of the base 2 .

[0085] Furthermore, the glass tube package 30G placed on the base 2 is covered with the second packaging film 52 from above.

[0086] Here, the portion of the first wrapping film 51 extending from the base 2 and the lower end portion of the second wrapping film 52 (the portion where the first wrapping film 51 and the second wrapping film 52 overlap) are thermally bonded to each other.

[0087] As a result, the loaded state (packaged state) of the glass tube package 30G loaded on the base 2 is firmly held on the base 2 in a sealed state by the packaging film 5 .

[0088] Next, the side protector 6 will be described.

[0089] The side protection member 6 is a member for covering corners of a glass tube package 30G composed of a plurality of glass tube assemblies 30, 30, ... placed on the base 2, that is, at least one corner portion 31A (in the present embodiment, all four corner portions 31A, 31A, 31A, 31A) of a plurality of (four) side portions 31, 31, 31, 31 of the glass tube package 30G, each formed by adjacent side portions 31, 31.

[0090] The side protection member 6 is formed of a plate-like member having cushioning properties and extending in one direction, such as corrugated cardboard, and is arranged in an L-shaped bent state so as to follow the corner portion 31A of the glass tube package 30G on the base 2 and contact the side portions 31, 31 constituting the corner portion.

[0091] It should be noted that the corner portion 31A may be in a circularly curved state.

[0092] Here, the side protection members 6 may be arranged at any position between the glass tube package 30G and the packaging film 5 (more specifically, the second packaging film 52 ) or outside the second packaging film 52 with respect to the corner portion 31A of the glass tube package 30G placed on the base 2 . However, in the present embodiment, the side protection members 6 are arranged between the glass tube package 30G and the second packaging film 52 .

[0093] With this structure, the side protectors 6 can be reliably held along the corners 31A of the glass tube package 30G by the packaging film 5 (second packaging film 52 ), and damage to the ends of the glass tubes located at the corners 31A caused by loads due to external impacts can be more reliably suppressed.

[0094] [Packaging Method of Glass Tube Assembly Package 1]

[0095] Next, use Figure 3 as well as Figure 4 A method of packaging the glass tube assembly package 1 will be described.

[0096] The packaging method of the glass tube assembly package 1 in this embodiment mainly includes: a first step of placing a plurality of glass tube assemblies 3, 3, ... (glass tube package 30G) on a base 2; a second step of disposing side protection members 6 so as to cover corner portions 31A (in this embodiment, all four corner portions 31A, 31A, 31A, 31A) of the glass tube package 30G; and a third step of covering the glass tube package 30G and the side protection members 6, 6, 6, 6 with a packaging film 5.

[0097] Specifically, first, as the first step, Figure 3 As shown in FIG. 2 ( a ), the first packaging film 51 is laid on the upper surface of the base 2 .

[0098] Here, the first packaging film 51 is formed to have a surface area sufficiently larger than the upper surface of the base 2 , and is laid in a state of hanging downward from the upper surface of the base 2 at a peripheral edge 51 a .

[0099] After the first wrapping film 51 is laid on the upper surface of the base 2, a predetermined number (for example, four in this embodiment) of glass tube assemblies 3, 3, ..., i.e., a glass tube assembly group 30 (hereinafter referred to as "first glass tube assembly group 30A" as needed) are arranged and placed on the upper surface of the base 2 with the first wrapping film 51 interposed therebetween.

[0100] After the first glass tube assembly group 30A is placed on the upper surface of the base 2 , a rectangular plate-shaped inner cushion member 4 (hereinafter referred to as “first inner cushion member 4A” as needed) is placed on the upper surface of the first glass tube assembly group 30A.

[0101] Thereafter, in the first inner cushion member 4A, portions extending from both sides in the width direction of the first glass tube assembly group 30A are bent downward.

[0102] As a result, the ear pieces 4 b and 4 b of the first inner cushion member 4A come into contact with both side surfaces in the width direction of the upper portion of the first glass tube assembly 30A.

[0103] As will be described later, the packaging film 5 firmly maintains the shape of the first inner cushion member 4A, thereby effectively preventing positional deviation in the width direction of the plurality of glass tube assemblies 3 , 3 . . . constituting the first glass tube assembly group 30A.

[0104] After both widthwise ends of the first glass tube assembly group 30A in the first inner cushion member 4A are bent downward, a predetermined number of glass tube assemblies 3, 3, ..., i.e., a glass tube assembly group 30 (hereinafter referred to as "second glass tube assembly group 30B" as needed) are arranged and placed on the upper surface of the first inner cushion member 4A.

[0105] After the second glass tube assembly group 30B is placed on the upper surface of the first inner gasket member 4A, a rectangular plate-shaped inner gasket member 4 (hereinafter referred to as “second inner gasket member 4B” as needed) is placed on the upper surface of the second glass tube assembly group 30B.

[0106] Thereafter, the portions of the second inner cushion member 4B that protrude from both sides in the width direction of the second glass tube assembly group 30B are bent downward.

[0107] As a result, the ear pieces 4 b and 4 b of the second inner cushion member 4B come into contact with both side surfaces in the width direction of the upper portion of the second glass tube assembly 30B.

[0108] In this manner, the placement of the glass tube assembly groups 30 and the placement of the inner cushion members 4 on the upper surfaces of the glass tube assembly groups 30 are repeated until the number of glass tube assembly groups 30 on the base 2 reaches a predetermined number (for example, eight in this embodiment).

[0109] In this way, the glass tube package 30G is formed.

[0110] It should be noted that, in the present embodiment, the inner cushion member 4 is placed on the upper surface of each stage of the glass tube assembly group 30, and both ends of the inner cushion member 4 in the left-right direction are immediately bent. However, the present invention is not limited to this. For example, after placing a predetermined number of glass tube assembly groups 30, 30, ..., the inner cushion member 4 may be bent collectively, or the inner cushion member 4 may be placed on the upper surface of each stage of the glass tube assembly group 30 with both ends of the inner cushion member 4 in the left-right direction bent.

[0111] When the number of glass tube assemblies 30, 30, ... on the base 2 reaches a predetermined number and the glass tube package 30G is formed, the first step is completed. Figure 3 As shown in (b) of FIG. 2 , as a second step, side protectors 6 , 6 , 6 , and 6 are respectively arranged along the corner portions 31A, 31A, 31A, and 31A at the four corners of the glass tube package 30G.

[0112] In the present embodiment, the side protectors 6 , 6 , 6 , 6 are respectively arranged along the corner portions 31A, 31A, 31A, 31A at all four corners. However, the side protector 6 may be arranged at at least one corner portion 31A.

[0113] When the side protection members 6, 6, 6, 6 are respectively arranged along the corner portions 31A, 31A, 31A, 31A of the four corners of the glass tube package 30G, the second step is completed. Figure 4 As shown in (a) of FIG. 1 , as a third step, the glass tube assembly groups 30 , 30 . . . together with the side protection members 6 , 6 , 6 , 6 are covered from above with a second packaging film 52 .

[0114] Here, the second packaging film 52 is formed to have an appropriate internal volume capable of accommodating the glass tube package 30G on the upper surface of the base 2 , and covers the glass tube package 30G with the opening edge 52 a hanging downward from the upper surface of the base 2 .

[0115] After the glass tube package 30G on the upper surface of the base 2 is covered with the second packaging film 52 , the glass tube assembly package 1 is placed in, for example, a heating device (not shown) and the entire package is heated.

[0116] Therefore, if Figure 4 As shown in (b), both the first packaging film 51 and the second packaging film 52 are thermally shrunk to form the glass tube assembly package 1 .

[0117] Here, the first wrapping film 51 and the second wrapping film 52 are set to have different thermal shrinkage rates. When the first wrapping film 51 and the second wrapping film 52 thermally shrink due to heating of the entire glass tube assembly package 1, the opening edge 52a of the second wrapping film 52 is thermally bonded to the edge 51a of the first wrapping film 51, then rolled up together with the edge 51a and welded to the lower portion of the edge of the upper surface of the base 2. Furthermore, the internal volume of the second wrapping film 52 is rapidly reduced by thermal contraction, thereby retaining the glass tube assembly groups 30, 30, ...

[0118] As a result, the glass tube assembly groups 30 , 30 , which are stacked in multiple stages on the upper surface of the base 2 with the inner cushion members 4 , 4 , . . . and the side protection members 6 , 6 , 6 interposed therebetween, are securely maintained in their loaded form (packaged form) by the heat-shrinking first and second packaging films 51 , 52 .

[0119] Furthermore, the glass tube assemblies 30, 30, ..., the inner cushion members 4, 4, ..., and the side protectors 6, 6, 6, which are firmly held in the loaded form (packaged form) by the first and second wrapping films 51, 52, are further firmly held relative to the base 2 by the edge 51a of the first wrapping film 51 and the opening edge 52a of the second wrapping film 52.

[0120] [Specific Structure of Bundling Film F and Wrapping Film 5]

[0121] The wrapping film 5 is formed to a predetermined thickness. The thickness t1 of the wrapping film 5 is 150 μm or more (see Figure 5 (a)), preferably 160 μm or more, more preferably 170 μm or more, further preferably 180 μm or more. The upper limit of the thickness t1 of the wrapping film 5 is not particularly limited, but is preferably 280 μm or less, more preferably 250 μm or less, for example.

[0122] By making the thickness t1 of the wrapping film 5 relatively thick in this manner, the wrapping film 5 more firmly maintains the loaded configuration (or packaged configuration) of the glass tube assembly 30G. Therefore, even if the glass tube assembly package 1 sways during transport, for example, the glass tube assembly group 30 covered by the wrapping film 5 can be prevented from swaying, thereby preventing contact between the glass tube assemblies 3. Consequently, even if the glass tube assembly package 1 sways, for example, damage to the glass tubes G due to contact between the glass tube assemblies 3 can be prevented.

[0123] Furthermore, by configuring the thickness t1 of the wrapping film 5 to be relatively thick, it becomes difficult for moisture to penetrate into the inner side of the wrapping film 5 , and it is possible to prevent condensation from occurring in the wrapping film 5 for a relatively long period of time.

[0124] The bundling film F is formed to a predetermined thickness. The thickness t2 of the bundling film F is 150 μm or less (see Figure 5 (b)), preferably 140 μm or less, more preferably 130 μm or less, and even more preferably 120 μm or less. It should be noted that the lower limit of the thickness t2 of the bundling film F is not particularly limited, but if it is too thin, holes will form in the bundling film F during heating. Therefore, it is preferably 50 μm or more, for example. By making the thickness of the bundling film F relatively thin in this manner, thermal shrinkage of the bundling film F during heating can be achieved in a relatively short period of time. Consequently, the process of bundling the plurality of glass tubes G, G, etc., which are assembled in multiple rows and stages, using the bundling film F can be performed efficiently, improving the workability of the packaging operation of the glass tube assembly package 1.

[0125] It should be noted that in this embodiment, the strapping film F is heated and thermally shrunk in the strapping step S103, but this is not limited to this. The strapping film F may also be heated and thermally shrunk before the placing step S101, before the covering step S102, or before the strapping step S103.

[0126] In the glass tube assembly package 1, the relationship between the thickness t1 of the wrapping film and the thickness t2 of the bundling film F satisfies predetermined conditions. Specifically, the thickness t1 of the wrapping film and the thickness t2 of the bundling film F satisfy the relationship t1 / t2 ≥ 1, preferably t1 / t2 > 1, more preferably t1 / t2 ≥ 1.2, and even more preferably t1 / t2 ≥ 1.3.

[0127] By making the thickness t1 of the wrapping film 5 relatively thick in this manner, the wrapping film 5 more firmly maintains the loaded configuration (or packaged configuration) of the glass tube assembly 30G. Therefore, even if the glass tube assembly package 1 sways during transport, for example, the glass tube assembly group 30 covered by the wrapping film 5 can be prevented from swaying, thereby preventing contact between the glass tube assemblies 3. Consequently, even if the glass tube assembly package 1 sways, contact between the glass tube assemblies 3 can be prevented, thereby preventing damage to the glass tubes G.

[0128] Furthermore, by configuring the thickness t1 of the wrapping film 5 to be relatively thick, it becomes difficult for moisture to penetrate into the inner side of the wrapping film 5 , and it is possible to prevent condensation from occurring in the wrapping film 5 for a relatively long period of time.

[0129] Furthermore, by making the bundling film F relatively thin, thermal contraction of the bundling film F during heating can be achieved in a relatively short period of time. Consequently, the process of bundling the plurality of glass tubes G, G, ..., assembled in multiple rows and stages, using the bundling film F can be performed efficiently, thereby improving the workability of the packaging operation of the glass tube assembly package 1.

[0130] In addition, the wrapping film F and the first and second wrapping films 51 and 52 constituting the wrapping film 5 may be formed of materials different from each other.

[0131] With such a structure, even if the first and second packaging films 51 and 52 during heat shrinkage come into contact with the bundling films 5 of the glass tube assemblies 3 , thermal adhesion between them can be prevented.

[0132] Alternatively, the wrapping film F may be formed of an inner and outer double structure, and the outer wrapping film F and the first and second wrapping films 51 and 52 constituting the wrapping film 5 may be formed of materials different from each other.

[0133] With such a structure, even if the first and second packaging films 51 and 52 during heat shrinkage come into contact with the outer bundling films F of each glass tube assembly 3 , thermal adhesion between them can be prevented.

[0134] The above describes an embodiment of the present invention, but the present invention is not limited to such an embodiment and is ultimately illustrative. Of course, it can be implemented in various ways without departing from the scope of the present invention. The scope of the present invention is represented by the description of the patent technical solution, and also includes the equivalent meanings recorded in the patent technical solution and all changes within the scope.
