DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube container storage box for transporting and storing empty tube containers before filling with contents.

[0002]

2. Description of the Related Art A tube container is screwed with a cap on a container neck having an outlet for the filling material until the filling material (fluid substance) is filled in the container, and the end of the tube body is closed. Handling in an open state requires a lot of care in handling such unfilled tube containers while transporting them from the manufacturing plant to a filling plant for drugs, etc., and is usually stored in a shipping box. Stored and distributed in a state.

[0003] In the tube container storage box, in order to facilitate the handling of the empty box for transportation and storage,
A separation type including a frame formed by bending a strip and a bottom lid has already been used.

[0004]

However, according to the prior art, as shown in FIGS. 8 and 9, in the case of a frame c formed by bending a belt-shaped body, the radius remains at the corners d. However, it was difficult to form an accurate rectangular frame c, and it was difficult to store an accurate number of tubes e. Further, as shown in FIG. 10, when the frame c is folded in an empty box state, it expands due to the restoring force of the corners d (where the radius is left). Sometimes it was not stable and was not easy to transport and store.

[0005] Further, when the tube container storage boxes made of plastic are stacked in an empty state, it is difficult to carry them in bulk. Furthermore, in the case of metal, the weight was large and it was difficult to handle. When formed of corrugated cardboard or cardboard, it is lightweight, but generates dust such as paper powder, which is unsuitable for products such as pharmaceuticals and foods where hygiene is important. Moreover, durability was not good either.

Therefore, according to the present invention, a tube container which is easy to handle, has no risk of damaging or deforming the tube container, and can store an accurate number of tube containers and maintain a clean use state. It is intended to provide a storage box.

[0007]

In order to achieve the above object, according to the present invention, a band made of a polyolefin-based low-medium foam material is cut into both side edges of the band by leaving predetermined small dimensions. A line is inserted, and the cut line is outwardly bent at 90 ° in the opening direction to form four corners, so that the entire frame forms a rectangular or square frame, and the shape of the frame is maintained. And a bottom cover externally fitted to the frame.

[0008] The width of the strip is 50 mm to 250 mm, the thickness of the strip is 1.5 mm to 5.0 mm, and the predetermined small dimension is set to 5 mm to 30 mm. Further, it is preferable that the bottom cover is configured to be deployable in a planar shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing embodiments.

FIG. 1 shows an embodiment (expanded state) of a tube container storage box according to the present invention. The tube container storage box 1 includes a frame 2 formed of a band-shaped material and a low-volume bottom cover 3.
And A method of assembling the tube container storage box 1 will be described. The band-shaped material shown in FIG. 1A is bent to form four corners 2a, and as shown in FIG. The frame 2 is constituted. Then, the frame 2 is fitted into the bottom cover 3 in the direction of the arrow A so that the shape of the frame 2 is maintained, and the bottom cover 3 is fitted over the frame 2 to form the tube container storage box 1.

More specifically, as shown in FIG. 2, a cut line 5 is formed in the strip material, and the cut line 5 is outwardly bent at an angle of θ = 90 ° in the opening direction to form a corner 2a. . Similarly, the remaining three corners 2a are formed to form the entire rectangular frame 2. Moreover, as shown in FIG.
It has an extension 4, as shown in FIG.
The frame 2 is formed so as to overlap the outer side of the adjacent side portion.

The portion overlapping with the extension 4 is
It is also preferable to fix (connect) the frame 2 with rivets, or to attach and detach the frame 2 by attaching a planar fastener or attaching male and female snaps. .

Further, the bottom cover 3 is configured to be deployable in a planar shape, and can be made compact in an empty box state. Examples of the unfolding method include, for example, a method in which adjacent end portions can be detachably attached to a side end portion of the bottom cover 3 by a sheet fastener, a snap type, a magnet type, or the like, or a side end portion of the bottom cover 3 is folded. There is a method such as doing.

FIG. 3 shows a state where the tube containers 6 are stored. Corner 2a (as shown in FIG. 2)
Is accurately bent to 90 ° to form a rectangular frame 2 that is entirely accurate, so that a fixed number of tube containers 6 can be arranged in a line and arranged neatly without gaps. Therefore, an accurate number of tube containers 6 can be stored.

As shown in FIGS. 4 and 5, when the frame 2 is folded, the frame 2 is bent along the cut line 5.
The radius does not remain at the corners 2a and does not expand outward due to elasticity. Therefore, it is possible to fold the frame 2 compactly without spreading it outward. Since the cut line 5 has predetermined small dimensions W, W on both side edges of the band-shaped body, there is no fear that a finger is caught in the cut line 5 at the time of bending.

The frame 2 can be freely changed in addition to the above embodiment. For example, as shown in FIGS. 6 and 7, the extension 4 need not be provided. In this case, as shown in FIG. 6, the both ends of the strip are formed by abutting each other,
As illustrated in FIG. 7, the tube container storage box 1 may be formed by forming the gap portion 7 in the corner 2 a of the frame body 2 and externally fitting the bottom cover 3.

Further, the tube container storage box 1 of the present invention comprises:
Polyolefin-based low to medium foam materials are used for the material. For example, polypropylene with an expansion ratio of 1.3 to 4 times,
It is preferable to use other low to medium foam materials. Further, the band-shaped material forming the frame 2 has a width of 50 mm to 250 mm and a thickness of 1.5 mm to 5.0 mm. further,
The predetermined small dimension W is set from 5 mm to 30 mm.

The reason why the above set values are provided will be described.
The reason why the material is limited to the low to medium foamed material is from the viewpoint of a balance between ease of handling during manufacture and durability against bending and the like. If the expansion ratio exceeds 4 times, the strength may be insufficient and the material may be broken. On the other hand, if the expansion ratio is less than 1.3 times, the material becomes too hard, which is difficult to handle.

The width of the strip material is set to 50 mm to 250 mm in accordance with the size of the tube containers 6 to be stored. The thickness is set in terms of both ease of handling and durability. That is, if the thickness is less than 1.5 mm, the strength and rigidity are insufficient, and the durability is inferior.
If it exceeds, the weight becomes excessive and it becomes difficult to handle. Further, if the predetermined small dimension W is less than 5 mm, the corners 2a may be broken, while if it exceeds 30 mm, it becomes difficult to bend.

Further, the tube container storage box 1 of the present invention.
May use the top lid, but without using the top lid
-28948 may be sealed with a heat-shrinkable film. When the upper lid is used, it can be freely removed together with the upper lid and the bottom lid 3. Therefore, when inspecting the tube containers 6. Has the advantage that it can be seen from both sides of the cap side and the hem side.

[0021]

The present invention has the following remarkable effects by the above-mentioned structure.

[0022] According to the first aspect, the tube container storage box 1 is composed of a frame 2 and a bottom cover 3 formed of a band-shaped material, so that parts management is easy and manufacturing costs are reduced. Can be reduced. Further, since the band-shaped material is bent 90 ° in the opening direction with the cut line 5 as the outer side to form the corners 2a, the entire shape becomes an accurate rectangle, and the orderly and accurate number of tube containers 6 are stored. can do.

Further, since the tube containers 6 can be stored neatly without gaps, the tube containers 6 do not fall down during transportation, and the tube containers 6 move in the storage box 1 to damage the tube containers 6. Or worry about it. The tube container storage box 1 is made of a polyolefin-based low-
Made of medium foam material, lightweight and shock resistant
Has water resistance. In addition, since dust such as paper dust does not occur, it is hygienic, and is particularly suitable when the contents of the tube containers 6 are important for hygiene such as pharmaceuticals and foods.

Further, since the frame 2 can be folded at the score line 5, the frame 2 can be made thin and compact.
When empty, it is easy to stack and space efficient during storage and transportation. Since the cut lines 5 are left on both side edges of the band-shaped material, leaving only a predetermined small dimension W, W, the fingers are not caught in the cut lines 5 at the time of folding, so that it is safe. Also, even when repeatedly used, since the predetermined small dimensions W, W are provided, the corners 2a are hardly broken, and the durability is good.

(According to claim 2), it is easy to handle and hardly broken even if it is repeatedly bent. In addition, it can be changed to a strip having a different size according to the size of the tube container 6 to be stored. Furthermore, by setting the predetermined small dimension W, it is easy to bend, and even if it is repeatedly bent, the corners 2a are hardly broken.

According to the third aspect, since the bottom cover 3 can be developed in a flat shape, it can be easily stacked in an empty box state and can be transported and stored compactly. Further, the inside of the bottom cover 3 can be always kept clean.
