  Next, embodiments of the invention will be described.

[Glass tube assembly package 1]
First, the whole structure of the glass tube assembly package 1 embodying the present invention will be described with reference to FIG.
In addition, regarding the following description, for convenience, the vertical direction in FIG. 1 is described as the vertical direction of the glass tube stack 1.
In FIG. 1, the direction of the arrow A is defined as being forward.

  The glass tube assembly package 1 in this embodiment is a package in which a plurality of glass tubes are accumulated in a stable form, and mainly includes a base 2, a glass tube assembly 3, an insole member 4, And the covering member 5 and the like.

The base 2 is a base of the glass tube assembly package 1.
The base 2 is made of an optimal material selected as appropriate, such as, for example, wood, metal, synthetic resin, or FRP (reinforced plastic), and is configured as a pallet (loading base) into which a forklift carrying claw can be inserted. .

  In addition, about the structure of the base 2, it is not limited to this embodiment, For example, in order to mount several glass tube integration | stacking 3 * 3 ... mentioned later in several rows and several steps | paragraphs Any structure may be used as long as it has a sufficient area and has rigidity capable of firmly supporting these glass tube stacks 3.

Next, the glass tube accumulation 3 will be described.
The glass tube accumulation 3 is constituted by a plurality of glass tubes (not shown) that are accumulated.
Here, the glass tube is a glass member used for, for example, a medical ampoule or a fluorescent tube for illumination, and is formed in a long hollow cylindrical shape.

The plurality of glass tubes are formed to have the same length, and are integrated in a plurality of rows and a plurality of stages.
The plurality of integrated glass tubes are packaged by wrapping paper or the like, and then shrink-wrapped using a shrink film (not shown) to form a glass tube integrated product 3.
Thereby, the glass tube accumulation | aggregation 3 is comprised by the elongate substantially rectangular parallelepiped shape, and a packaging form is firmly hold | maintained by the said shrink packaging.

As described above, in the glass tube assembly 3 of the present embodiment, the packaging form of a plurality of glass tubes is held by shrink packaging, but is not limited thereto.
That is, it is good also as winding the circumference | surroundings of the several glass tube wrapped, for example using a stretch film etc., applying moderate tension | tensile_strength, and finally hold | maintaining the packaging form of the said several glass tube.

A plurality of glass tube stacks 3, 3... Configured in this way are prepared for each stage on the base 2 (for example, four in this embodiment), and the longitudinal direction is the front-rear direction ( 1 in parallel with the arrow A in FIG. 1 in the left-right direction (in the direction orthogonal to the longitudinal direction in plan view).
And the glass tube accumulations 3, 3... (Hereinafter referred to as “glass tube accumulation group 30” as appropriate) arranged in a plurality of rows at each stage are placed on the base 2 as insole members described later. 4 is mounted.
That is, on the base 2, a plurality of glass tube assembly groups 30, 30... Are sandwiched between the insole members 4, 4,. Eight steps).

Next, the insole member 4 will be described.
The insole member 4 is a member interposed as a cushioning material that is stacked on the base 2 and disposed between the plurality of glass tube aggregates 30.
The insole member 4 is formed of corrugated cardboard having a rectangular sheet shape.

  The insole member 4 is placed so as to cover the entire upper surface of the glass tube assembly group 30 in each stage.

Here, the longitudinal dimension of the insole member 4 (dimension in the front-rear direction of the insole member 4) is approximately the same as the longitudinal dimension (front-rear direction) of the glass tube assembly 30 (dimension X in FIG. 1) ( It is set so as not to be larger than the longitudinal dimension of the glass tube assembly 30.
Further, the lateral dimension of the insole member 4 (dimension in the left-right direction of the insole member 4) is somewhat larger than the dimension in the width direction (left-right direction) of the glass tube assembly group 30 (dimension Y in FIG. 1). Is set to a value.

The insole member 4 is interposed between the glass tube accumulation groups 30 and 30 adjacent to each other in the vertical direction, and disposed on the upper surface of the uppermost glass tube accumulation group 30. Both ends in the left-right direction are placed so as to protrude to both sides in the width direction of the glass tube assembly 30.
Further, the left and right end portions of the insole member 4 protruding from the glass tube accumulation group 30 are bent downward along the side surface of the glass tube accumulation group 30. At this time, the insole member 4 is formed by bending the left and right ends of the insole member 4 along the side along the longitudinal direction of the glass tube assembly group 30.

  Thus, the insole member 4 becomes a “U” -shaped plate-like member that opens downward, and has a top plate portion 4 a having substantially the same shape as the upper surface of the glass tube assembly group 30, and the top plate portion 4 a. A pair of ear pieces 4b and 4b (only one piece is shown for the perspective view in FIG. 1) that hangs down along the mutually opposing edges.

  Therefore, as will be described later, the covering form 5 securely holds the packaging form of the entire glass tube assembly package 1 and the form of the insole member 4 is firmly held, so that it is parallel to each stage. The positional displacement and load collapse in the width direction of the plurality of glass tube stacks 3,... Arranged are effectively prevented by the insole member 4.

Specifically, by covering the plurality of glass tube stacks 30, 30,... Stacked on the base 2 with the covering member 5, the ear pieces 4 b, 4 b are outermost in each stage. In order to restrain the glass tube accumulation group 30 at the corresponding stage in contact with the side surface of the glass tube accumulation 3 located at the position of the cover member 5 as in the prior art, By being in contact with the side end portion and being strained, a gap is generated between the side surface of the glass tube assembly 3 positioned on the outermost side of each step and the covering member 5, so that the glass tube assembly 3 is misaligned. It is possible to prevent the occurrence of load collapse.
Further, for example, during the transportation of the glass tube assembly package 1, the protruding portion of the insole member 4 is bent due to an unexpected impact from the outside, and the tensioned covering member 5 is loosened, so that the glass tube It is possible to prevent the displacement of the accumulation 3 and the collapse of the load.

In the present embodiment, the pair of ear pieces 4b and 4b are provided in the left-right direction of the insole member 4, but the present invention is not limited to this. Ear pieces 4b and 4b may be provided.
Thereby, the positional shift about the longitudinal direction of the some glass tube integration | stacking 3 * 3 ... arrange | positioned in parallel with each step | stage can also be prevented effectively.
However, in these glass tube accumulations 3, 3..., The positional deviation in the longitudinal direction is less generated than the positional deviation in the width direction, so at least the lateral direction of the insole member 4 Are bent sufficiently, the effect of preventing the displacement of the insole member 4 with respect to the plurality of glass tube assemblies 3, 3... Is sufficiently exhibited.

In the present embodiment, the left and right ends of the pair of ear pieces 4b and 4b of the insole member 4 are bent downward, but the present invention is not limited to this. For example, It is good also as restricting the position shift in the width direction of a plurality of glass tube accumulation object groups 30 and 30 arranged on the upper surface of the glass tube.
However, in this case, in the subsequent process, while the plurality of glass tube accumulation groups 30, 30... On the base 2 are covered from above with the covering member 5 (for example, a shrink film described later), the medium is always in the middle. It is necessary to hold the left and right ends of the laying member 4 in a state of being bent upward, which may reduce work efficiency.
Therefore, as shown in the present embodiment, when the pair of ear pieces 4b and 4b of the insole member 4 are bent downward, there is no possibility that the working efficiency is lowered, and the glass tube integrated body It is possible to easily prevent positional deviation of the group 30 and the like.

  In the present embodiment, the four corners of the insole member 4 (in other words, the corner portions 4c, 4c... Of the pair of ear pieces 4b, 4b of the insole member 4) are each formed in an arc shape. For example, when the four corners of the insole member 4 are in contact with the covering member 5 covered around the plurality of glass tube stacks 30, 30... Stacked on the base 2, The generation of defects or the like in the covering member 5 is to be prevented as much as possible.

Next, the covering member 5 will be described.
The covering member 5 holds the glass tube aggregates 30, 30... Stacked in a plurality of stages on the base 2 with respect to the base 2 while maintaining the overall stacking form (or packing form). It is a member for holding it firmly.
The covering member 5 is formed of, for example, a shrink film in the present embodiment.

  The material of the covering member 5 is not particularly limited, and any material such as PVC (polyvinyl chloride), PP (polypropylene), or PE (polyethylene) may be used.

The covering member 5 is not limited to the shrink film as shown in the present embodiment, and may be formed of, for example, a polyethylene stretch film.
However, when using a stretch film, it is necessary to wind around a plurality of glass tube stacks 30, 30... Stacked on the base 2 while applying a certain tension. In the case of using a film, it is not necessary to perform such work, and the work burden can be reduced, which is more preferable.

The covering member 5 includes a sheet-shaped first covering member 51, a bag-shaped second covering member 52 (see FIG. 2), and the like.
Then, as will be described later, the glass tube stack group 30 (more specifically, the first glass tube stack group 30A, see FIG. 2) loaded on the lowermost stage on the base 2, and the base 2 The first covering member 51 is laid between the two. The first covering member 51 is formed larger than the upper surface of the base 2 and protrudes in the front-rear and left-right directions of the base 2.
Further, the glass tube aggregates 30, 30... Stacked in a plurality of stages on the base 2 are encapsulated from above by the second covering member 52. The lower end portion of the second covering member 52 that encapsulates the glass tube accumulation group 30, 30... Reaches the lower end portion of the base 2, and is a portion that protrudes from the base 2 of the first covering member 51. Is superimposed.

In such a state, when the covering member 5 is made of a shrink film, the whole is heated.
Then, the first covering member 51 and the second covering member 52 undergo thermal contraction all at once. Further, when heated, the portion of the first covering member 51 that protrudes from the base 2 and the lower end portion of the second covering member 52 (the portion where the first covering member 51 and the second covering member 52 overlap each other) ) Fused together.
As a result, the plurality of glass tube stacks 30, 30... Stacked on the base 2 are held in the overall stacking form (packing form) by the covering member 5 and are attached to the base 2. It is firmly held against it.

[Packing method]
Next, a method for packing the glass tube assembly package 1 will be described with reference to FIG.

3A and 3B, the direction of the arrow A is defined as the front.

The glass tube stacks 101 and 201 in the second and third embodiments have substantially the same configuration as the glass tube stack 1 described above, while the glass tube stacks in the shape of the insole members 104 and 204. It is different from the package 1.
Therefore, in the following description, the difference from the glass tube assembly package 1 is mainly described, and the description of the same configuration as the glass tube assembly package 1 is omitted.

As shown in FIG. 3A, the insole member 104 is provided in the glass tube assembly package 101 in the second embodiment.
The insole member 104 is formed of rectangular sheet-shaped corrugated cardboard, and each stage of the glass tube accumulation group 130 on the base 102 (a plurality of glass tube accumulations 103, 103,... Arranged in a plurality of rows). It is mounted on the upper surface.

Here, the longitudinal dimension of the insole member 104 (the dimension Xa in the front-rear direction of the insole member 104) is the same as the dimension in the longitudinal direction (front-rear direction) of the glass tube assembly 130 (dimension X1 in FIG. 3A). It is set to be shorter than that.
Specifically, the longitudinal dimension Xa of the insole member 104 is set to be more than half of the longitudinal dimension X1 of the glass tube assembly group 130 and less than the longitudinal dimension X1 (( 1/2) × X1 <Xa <X1).

  Further, the horizontal dimension of the insole member 104 (the dimension in the left-right direction of the insole member 104) is compared with the dimension in the width direction (left-right direction) of the glass tube assembly group 130 (dimension Y1 in FIG. 3A). It is set to a somewhat large value.

And, the insole member 104 has both ends in the longitudinal direction of the upper surface of the glass tube aggregate group 130 on the upper surface in the longitudinal direction (front and rear direction) without protruding to both sides in the longitudinal direction of the glass tube aggregate group 130. In addition, the both ends in the left-right direction are placed so as to protrude to both sides in the width direction of the glass tube accumulation group 130, and are sandwiched between the glass tube accumulation groups 130 and 130 adjacent in the vertical direction. It is arranged on the upper surface of the uppermost glass tube stack group 130.
Further, the left and right end portions of the insole member 104 protruding from the glass tube accumulation group 130 are bent downward along the side surface of the glass tube accumulation group 130. At this time, the insole member 104 is formed by bending the left and right ends of the insole member 104 along the side along the longitudinal direction of the glass tube assembly 130.

  Thus, the insole member 104 of the glass tube stack package 101 in the second embodiment is a “U” -shaped plate-like member that opens downward, compared to the upper surface of the glass tube stack group 130. A top plate portion 104a that is short in the longitudinal direction and a pair of ear pieces 104b that are suspended along the mutually opposing edges of the top plate portion 104a (in FIG. 3A, only one piece is shown for perspective view). 104b.

On the other hand, as shown in FIG.3 (b), the insole member 204 is provided in the glass tube integrated body package 201 in 3rd embodiment.

Here, the longitudinal dimension of the insole member 204 (the dimension Xb in the front-rear direction of the insole member 204) is the same as the dimension in the longitudinal direction (front-rear direction) of the glass tube assembly 230 (dimension X2 in FIG. 3B). It is set to be shorter than that.
Specifically, the longitudinal dimension Xb of the insole member 204 is set to be less than half of the longitudinal dimension X2 of the glass tube assembly group 230 (0 <Xb <(1/2) × X2 ).

  Further, the lateral dimension of the insole member 204 (the dimension in the left-right direction of the insole member 204) is compared with the dimension in the width direction (left-right direction) of the glass tube assembly group 230 (dimension Y2 in FIG. 3B). It is set to a somewhat large value.

For example, the pair of insole members 204 and 204 are separated from each other in the longitudinal direction (front-rear direction) on the upper surface of the glass tube assembly group 230 at each stage, and both ends in the front-rear direction are the glass tube assembly group 130. The glass tube stacks 230 are placed so as not to protrude to both sides in the longitudinal direction and so that both ends in the left and right direction protrude to both sides in the width direction of the glass tube stacks 130 and are adjacent to each other in the vertical direction. 230 and is disposed on the upper surface of the uppermost glass tube assembly 230.
Further, the left and right end portions of each insole member 204 protruding from the glass tube accumulation group 230 are bent downward along the side surface of the glass tube accumulation group 230. At this time, the insole member 204 is formed by bending the left and right ends of the insole member 204 along the side along the longitudinal direction of the glass tube assembly 230.

  Thus, the insole member 204 of the glass tube stack package 201 in the third embodiment is a “U” -shaped plate-like member that opens downward, compared to the upper surface of the glass tube stack group 230. A top plate portion 204a that is short in the longitudinal direction and a pair of ear pieces 204b that hang down along opposite edges of the top plate portion 204a (in FIG. 3 (b), only one piece is shown for a perspective view). -It will be comprised from 204b.

As described above, the insole member 104 in the second embodiment (hereinafter referred to as “second insole member 104” as appropriate) and the insole member 204 in the third embodiment (hereinafter referred to as “third” as appropriate). The insole member 204 ”is set so that the longitudinal dimensions Xa and Xb are shorter than the longitudinal dimensions (front and rear directions) X1 and X2 of the glass tube assembly group 130 and 230. .
Therefore, for example, as in the case of the insole member 4 (see FIG. 1) described above, it is necessary as compared with the case where the glass tube assembly group 30 is formed with a longitudinal dimension substantially the same as the longitudinal dimension X. The size of the material (corrugated cardboard) can be small, and the second insole member 104 and the third insole member 204 can reduce the manufacturing cost.

In addition, for example, when a part of the end portion in the longitudinal direction (front-rear direction) of the insole member protrudes between a plurality of glass tube stacks stacked on the base, the plurality of glass tube stacks The covering member that covers the periphery of the object group is in contact with the protruding portion of the insole member and is tensioned, and a gap is generated between the side surface of each stage of the glass tube assembly group and the covering member, Misalignment and load collapse of the glass tube stack will occur.
In such a case, it is conceivable that the protruding portion of the insole member is bent along the side surface in the longitudinal direction (front-rear direction) of the glass tube assembly group. Both end portions in the direction (left and right direction) are bent to form the ear pieces 4b and 4b, and the rigidity against bending stress at both ends in the longitudinal direction (front and rear direction) is improved, so the protruding portion is bent. It is practically difficult. It should be noted that, by separately processing the protruding portion consisting of both ends in the longitudinal direction (front-rear direction) of the insole member 4, the protruding portion can be bent, but the manufacturing cost increases. Will be invited.
In this respect, according to the second insole member 104 and the third insole member 204 in the second and third embodiments, the longitudinal dimensions Xa and Xb are both in the longitudinal direction (front and back) of the glass tube assembly group 130 and 230. )), The plurality of stacked glass tube stacks 130, 130, or the stacked glass tube stacks 130, 130,. Since the end portion in the longitudinal direction (front-rear direction) does not protrude from the gap, it can be easily placed at a predetermined placement position, and the above-described problems can be easily avoided.
