Description

  The present invention relates to an assembly container for a roll-like object. More specifically, when not in use, the member can be thinned into a single plate, so that the storage and transport efficiency is high, and the assembly is easy and easy to assemble during assembly. The present invention relates to an assembly container for a roll-shaped object that is strong and easy to disassemble.

  Conventionally, a roll-shaped product obtained by winding a strip-shaped product such as a dry resist, a plastic film, a metal foil, and thin paper around a core tube is brought into contact with a bowl-shaped protector from both sides of the roll-shaped product. It is housed in a container such as a cardboard box in a state of being floated from the floor, and is used for storage and transportation.

  However, since the size of the roll-like material varies depending on the product, the roll-like material cannot be efficiently stored in one type of normal container. Therefore, a container having a different size corresponding to the type of the roll-shaped object is prepared in advance, or a large container is prepared and a roll-shaped object having a different size is once stored in the container, and then one of the side walls of the container. A method is adopted in which a space formed on the other side wall is brought into contact with the end, and a cushioning material such as foamed polystyrene is filled to eliminate a gap so that the entire roll-shaped object is prevented from moving in the container.

  However, when preparing several kinds of containers of various sizes according to the size, not only a large space is required for storage, but also the transportation efficiency is poor, which causes an extra labor cost and increases the cost. It was also a factor.

In addition, when a large container is prepared and cushioning material such as expanded polystyrene is packed in the open gap, the workability is extremely poor, and these expanded polystyrene is not recycled and is incinerated on the destination side as waste after use. There is a problem that the incinerator is damaged when it is incinerated and causes environmental pollution.
Also, when recycling, since the materials of the container and the buffer material are different, it is necessary to separate and recycle, which increases the cost of recycling and makes recycling difficult.

Therefore, an attempt has been made to reduce the cost by assembling a member that becomes one thin plate when stretched to create a container, thereby reducing the storage space of the container before assembly. For example, a waste paper material pass box has been proposed in which a pair of first side plates are engaged in an engagement groove of a main body bent into a quadrangular prism shape (Patent Document 1). However, in such a box, if the bottom plate, the cover plate, and the second side plate forming the main body are thinned, the engagement groove is too shallow, the first side plate is easily detached, the strength is weak, and the box has sufficient strength. If the groove is made deeper, the bottom plate, the cover plate, and the second side plate forming the main body become too thick, so that the space required for storage becomes large, and it becomes heavy and difficult to handle.
Further, in this waste paper material pass box, the engagement groove and the first side plate are completely engaged only after the bottom plate, the cover plate, and the second side plate are bent into a quadrangular column shape. In this state, the box is sealed. For this reason, it is not possible to put a roll-like material inside. Then, with the cover plate open, the bottom plate and the second side plate are engaged with the first side plate and then the roll-shaped object is accommodated in the box. In this case, the first side plate and the second side plate are combined. Since the strength is not sufficient, there is a risk that the second side plate will open unexpectedly. In order to prevent this, it is necessary to support the second side plate with a hand so as not to open it, and the work becomes complicated.

  In order to solve the above-mentioned conventional problems, the present invention increases the thickness of a plate-like member in a container formed by assembling a member that has a small storage space and can be easily transported, such as a plate shape when not in use. The present invention provides an assembly container that can increase the bonding strength between members without being used, and can be easily assembled when used as a container, and can be easily disassembled before assembly when not required. Objective.

  In order to achieve the above object, claim 1 of the present invention is an assembly container for a roll-like product that protects and stores a roll-like product obtained by winding a strip-shaped product around a core tube, and includes two peripheral plates and It consists of two end face plates, and the peripheral face plate is connected to the center surface of a rectangle wider than the diameter of the roll-like product and longer than the width of the belt-like product, and 2 connected to both sides in the width direction via hinges. The end face plate is formed with a holding hole for holding the core tube of the roll-like material at the center portion of the end face plate. An assembly container for a roll-like object is characterized in that an occlusal slit is provided in the vicinity of both sides of the upper and lower edges and in the vicinity of both sides of the open edge of the side surface of the peripheral plate.

  Claim 2 of the present invention is a cap having a head having a larger diameter than a holding hole drilled in the center of the end face plate, and a core tube holding portion having a diameter substantially equal to the inner diameter of the core tube of the roll-shaped object to be stored. The assembly container for a roll-shaped object according to claim 1, which is fitted into a holding hole of the end face plate.

  According to a third aspect of the present invention, the sum of the widths of both lateral side surfaces of the peripheral plate is larger than the width of the central surface, and the slit provided on one of the upper and lower edges of the end plate is the other facing the slit. The assembly container for rolls according to claim 1 or 2, characterized in that it is provided by being shifted by a thickness of about one sheet of the peripheral plate and the slit provided at the edge.

  According to a fourth aspect of the present invention, the peripheral surface plate and the end surface plate are made of plastic corrugated cardboard, and the slit is formed in parallel with the rib of the plastic corrugated cardboard so as not to cut out the rib. The assembly container for rolls according to any one of claims 3 to 4 is included.

  The roll-like object assembly container of the present invention comprises two peripheral plates and two end plates. When the peripheral plate is unfolded (when extended), it becomes one thin plate, so the peripheral plate is also an end plate. The space for storage is very small, and it can be stored and transported very efficiently. If the diameter is the same, rolls of various lengths can be obtained by changing only the peripheral plate without changing the end plate. Therefore, the number of parts can be reduced. In addition, since the peripheral surface plate and the end surface plate are coupled by engaging the slits provided in each, the coupling strength between the members is strong. Furthermore, it is easy to fold one peripheral plate into a U-shape, join two end plates to both sides, and fold another peripheral plate into a U-shape and combine it. Can be assembled, and can be easily disassembled by performing the reverse operation. In addition, by folding one peripheral plate into a U-shape and joining the two end plates to both ends thereof, the lid is removed with a normal container, so the peripheral plate and end plate can be removed by hand. It is possible to easily take in and out the roll without supporting, and if one end face plate is further removed from this state, not only the upper side but also the side will be opened, so from the side open part It is also possible to take in and out the roll.

  If a cap having a head having a diameter larger than that of the holding hole and a core tube holding part having a diameter substantially equal to the inner diameter of the core tube of the roll-shaped object to be accommodated is fitted into the holding hole of the end face plate, the core tube is hollow. By inserting the core tube holding part into the part, it is possible to suitably hold a roll-like object in which the core tube does not protrude from the end face.

  The sum of the widths of both lateral sides of the peripheral surface plate is made larger than the width of the central surface, and a slit provided on one of the upper and lower edges of the end surface plate is provided on the other edge facing this slit. If the slit and the circumferential plate are shifted by the thickness of about one sheet, the lateral side surfaces of the opposing circumferential plate partially overlap, so that dust or dust enters the gap between the lateral sides, and rolls are removed. No fear of getting dirty.

  If the peripheral plate and end plate are made of plastic cardboard and the slits are formed in parallel with the ribs of the plastic cardboard and do not cut out the ribs, the strength of the plastic cardboard is hardly attenuated even if the slits are formed. It becomes difficult to improve durability.

  The roll-shaped product assembly container 1 of the present invention protects and stores a roll-shaped product R formed by winding a strip-shaped product around a core tube R1, as typically shown in Example 1 described in FIGS. An assembly container 1 for a roll-shaped object, which is composed of two peripheral surface plates 2 and two end surface plates 3, and the peripheral surface plate 2 is wider than the diameter L1 of the roll-shaped material and wider than the width L2 of the strip-shaped product. It consists of a long square central surface 2a and two lateral side surfaces 2c connected to both sides in the width direction via hinges 2b, and the sum of the widths of the lateral side surfaces 2c is equal to or greater than the width of the central surface 2a. The end face plate 3 is formed with a holding hole 3a for holding the core tube R1 of the roll-like material at the center thereof, near both sides of the upper and lower edges 3b of the end face plate 3, and the open edge 2d of the side face 2c of the peripheral face plate 2 An occlusal slit 4 is provided in the vicinity of both sides.

As shown in FIG. 2 (a), the peripheral surface plate 2 in the present invention has a lateral side surface 2c connected to both sides in the width direction of a rectangular central surface 2a via hinge portions 2b, and an open edge of the lateral side surface 2c. Slits 4 are provided near both sides of 2d.
As shown in FIG. 1, the peripheral surface plate 2 is formed by combining two peripheral surface plates 2 that are bent at a hinge portion 2 b to have a substantially U-shape, and is preferably a quadrangular column having a substantially square cross section. 1 peripheral surface. In this embodiment, since the sum of the widths of the lateral side surfaces 2c and the width of the central surface are equal, if assembled so that the open edges 2d of the respective lateral side surfaces 2c of the two peripheral plates 2 are brought together, Exactly, the cross section is a quadrangular prism having a substantially square cross section, but the cross section is obtained by making the sum of the widths of the lateral side surfaces 2c larger than the width of the central surface and overlapping the lateral side surfaces 2c of the opposed peripheral plates 2 somewhat. You may make it become a substantially square.

As shown in FIG. 2 (b), the end face plate 3 in the present invention is generally rectangular as a whole, and a holding hole 3a for holding the core tube of the roll-like object R is formed at the center thereof. The slits 4 are provided in the vicinity of both sides of the upper and lower edges 3b (hereinafter abbreviated as the upper and lower edges 3b).
As shown in FIG. 1, the end face plates 3 are disposed on both end sides of the peripheral face plate 2 assembled in a quadrangular prism shape, and serve as end faces of the roll-like object assembly container 1.

The roll-like assembly container 1 of the present invention comprises two peripheral plates 2 and two end plates 3, and since the peripheral plate is extended into a single thin plate, the peripheral plate and the end plate are stacked. Therefore, the space for storage and transportation can be extremely small, so that storage and transportation can be performed very efficiently.
Moreover, it can respond | correspond to the roll-shaped object R of various length with a limited kind of components, for example, if the diameter of a roll-shaped object is the same, by changing only the peripheral surface plate 2 without changing the end surface plate 3 Since it can be set as the container 1 which can accommodate the roll-shaped object R from which length differs, even when handling many types of roll-shaped objects R, a number of parts can be reduced and management cost can be reduced.

The peripheral plate 2 and the end surface plate 3 are each provided with the slits 4 as described above. As shown in FIG. 1, the peripheral surface plate 2 and the end surface plate 3 are joined by engaging the slits 4 with each other. At the same time, by assembling all the slits 4, the roll-like assembly container 1 of the present invention is completed.
More specifically, one peripheral surface plate 2 is bent in a U-shape, and the slits 4 on both sides and the slits 4 on the side of the end surface plate 3 are engaged to join the two end surface plates. After folding one peripheral surface plate 2 into a U-shape, the slits 4 can be engaged with each other and combined in the same manner as described above to easily assemble. Further, after use, it can be easily disassembled by a simple method of pulling out the upper peripheral plate 2 and then pulling out the end plate 3.

In the present invention, the width of the slit 4 is usually about the thickness of the peripheral surface plate 2 or the end surface plate 3, but either the peripheral surface plate side or the end surface plate side, or both slits 4 are connected to the peripheral surface plate 2 or The bonding strength may be increased by making the thickness slightly smaller than the thickness of the end face plate 3 and press-fitting using elasticity.
The positions of the slits 4 are near both sides of the opening edge 2d of the peripheral surface side surface 2c and near both sides of the upper and lower edges 3b of the end surface plate 3, but when they are too close to the end, between the slit 4 and the end Therefore, it is preferable to maintain an interval that does not cause damage in consideration of the strength of the material and use conditions.

The material of the peripheral surface plate 2 and the end surface plate 3 is not particularly limited, and ABS (acrylonitrile-butadiene-styrene copolymer resin), AAS resin (acrylonitrile / acrylic rubber / styrene), AES resin (acrylonitrile / ethylene propylene rubber / styrene), AS resin (acrylonitrile / styrene), PS resin (polystyrene resin), PMMA resin, PVC resin, MS resin (methyl methacrylate / styrene resin), PP (polypropylene resin), PE (polyethylene resin), PBT (polybutylene terephthalate resin) Any material can be used as long as it can protect the contents, such as resin such as PC resin (polycarbonate resin), paper or cardboard, paper or cardboard laminated with a resin film, wood, bamboo, metal, etc. ,lightweight, From the viewpoint of low cost and ease of molding, it is preferable to use a resin.
In particular, if a so-called plastic corrugated cardboard in which two plastic thin plates are bonded through a large number of ribs 5 extending in parallel is used, it has a light weight and sufficient strength, and further has an impact resistance and It is preferable because of its excellent water resistance. Further, it is preferable to provide the slits 4 in the portion between the ribs 5 in the present invention so that the ribs 5 are not cut out, because the strength of the peripheral surface plate 2 and the end surface plate 3 is hardly lowered.

The roll-shaped product assembly container 1 assembled as described above holds the roll-shaped product R by inserting the core tube R1 of the roll-shaped product R through the holding hole 3a formed in the end face plate 3.
In order to accommodate the roll-shaped material R in the roll-shaped material assembly container 1 of the present invention, for example, first, as shown in FIG. 2 is removed, or one peripheral surface plate 2 and two end surface plates 3 are assembled, so that the upper side is opened, and then the roll R is put into the container and the core is held in the holding hole 3a. The pipe R1 is inserted, and finally the remaining peripheral surface plate 2 is assembled. In such an assembly container 1 for a roll-shaped object, since the shape of the peripheral surface plate 2 is held in a substantially U shape when the end surface plate 3 is assembled to one peripheral surface plate 2, for example, the box of Patent Document 1 As described above, the roll-shaped object R can be easily and reliably accommodated in the container without fear of the lateral side surface 2c opening unexpectedly during the accommodating operation.
In addition, the center surface 2a of the peripheral surface plate has a rectangular shape that is wider than the diameter L1 of the roll-like material and longer than the width L2 of the belt-like product, and the surface obtained by combining the lateral side surfaces 2c of the opposed peripheral surface plates 2 is substantially the same. Therefore, the surface of the roll-shaped object R does not rub against any peripheral surface.
In addition, you may interpose a buffer material between the roll-shaped object R and a container inner wall surface as needed. Moreover, it can also adhere | attach to the meeting surface of the side surface 2c of the upper peripheral board 2 and the side surface 2c of the lower peripheral board 2 with an adhesive tape.

  When the core tube R1 does not protrude from the end face of the roll R and the core tube R1 cannot be inserted into the holding hole 3a, the holding tube 3a as shown in FIG. The roll-shaped object R is held using a cap 6 having a head 6a having a large diameter and a core tube holding portion 6b having a diameter substantially equal to the inner diameter of the core tube R1. In this case, as shown in FIG. 4A, the roll-shaped object R is suitably accommodated in the container by inserting the core tube holding portion 6b through the holding hole 3a and fitting into the core tube R1. .

Next, a second embodiment of the roll-like assembly container 1 of the present invention will be described with reference to FIGS.
In the present embodiment, plastic corrugated cardboard is used as the material, and the sum of the widths of the side surfaces is wider than the width of the center surface, and the side surfaces partially overlap when assembled. In FIGS. 5A and 5B, a linear alternate long and short dash line indicates the rib 5.

  FIG. 5A shows the peripheral plate 2 used in this embodiment. In the peripheral surface plate 2, the slits 4 are provided between the ribs 5 made of cardboard plastic in parallel with the ribs, and the ribs 5 are not cut out. Moreover, a part of rib is cut in the hinge part 2b so that it may not interfere with bending.

  FIG. 5B shows the end face plate 3 used in this embodiment. Also in this end face plate 3, the slit 4 is provided between the ribs 5 made of cardboard plastic in parallel with the rib, and the rib 5 is not cut out. However, in the case of the present embodiment, the slits respectively provided on the upper and lower edges 3b are not completely opposed to each other, and are provided by being shifted by the thickness of about one peripheral plate 2. Specifically, the slit 4 is provided on the right side of the rib 5 on the lower edge and on the left side of the rib on the upper edge with the fourth rib 5 from the left and right edges in FIG.

  As described above, the width of the slit 4 is substantially the same as the thickness of the peripheral surface plate 2 or the end surface plate 3, that is, the thickness of the plastic cardboard in this embodiment. In a normal case, since the thickness is slightly larger than the thickness of the plastic cardboard, it is easy to form the slit 4 so as not to damage the rib 5.

When the peripheral surface plate 2 in FIG. 5A and the end surface plate 3 in FIG. 5B are assembled, as shown in FIG. 6A, a part of the lateral surface 2c is overlapped. For this reason, there is no possibility that dirt, dust, or the like enters from between the lateral side surfaces 2c to contaminate the surface of the roll-shaped object R.
As shown in FIG. 6B, if the upper peripheral plate 2 is made slightly larger and the lower peripheral plate 2 is made large enough to fit under the upper peripheral plate 2, dust and In addition to preventing the entry of dust and the like, the lateral side surface 2c of the upper peripheral surface plate 2 covers the lateral side surface 2c of the lower peripheral surface plate 2. Therefore, even if liquid such as rainwater is applied from above, Is preferable because it does not enter.

As mentioned above, although the preferable aspect of this invention was demonstrated based on the Example, this invention is not limited only to these Examples, A various variation is possible without deviating from the summary of this invention. Needless to say.
For example, instead of the circular holding hole 3a shown in the figure, a U-shaped one can also be adopted. In this case, when storing the roll-shaped object R from which the core tube R1 protrudes, the core protruding from the U-shaped upper opening is used. By introducing the tube R1, it can be easily accommodated.

  As described above, according to the assembly container for a roll-like object of the present invention, the member can be thinned into a single plate at the time of storage, the storage efficiency is high, and the coupling strength between the members at the time of assembly is strong, Since assembly and disassembly is easy, it is useful as a container used for storing and transporting rolls.
