Description

  The present invention relates to a roll paper packaging structure, and more particularly to a coreless roll paper packaging structure having no winding core.

Conventionally, roll paper has been used for recording apparatuses such as business printers. However, coreless roll paper in which the core is omitted as disclosed in Patent Document 1, for example, due to demands for cost reduction and resource saving. Is popular. Since such a coreless roll paper does not have a core, the core of the roll paper is held from both ends by a conventionally used packing structure, that is, a holding member installed in an outer box for storing the roll paper. A packing structure (for example, Patent Document 2) cannot be used. Therefore, as a packing structure of the coreless roll paper, a packing structure in which holding members that hold the outer peripheral surface at both ends of the coreless roll paper are installed in the outer box is conceivable.
No. 7-42766 JP-A-7-69341

  However, in the type of packing structure in which the holding member holds the outer peripheral surface of the roll paper as described above, it is necessary to make it larger than the holding member of the type that holds the core in order to maintain the strength of the holding portion. As a result, the outer box in which the holding member is installed also becomes larger, which causes a problem that the transportation cost increases.

  Then, this invention makes it a subject to provide the packaging structure of roll paper which can hold | maintain coreless roll paper, maintaining a transportation cost.

  The roll paper packing structure according to the present invention is made in order to solve the above problems, and the shaft portion is a hollow portion, and is a structure for packing coreless roll paper having no winding core. And an outer box for storing the roll paper, a base portion having an outer shape that fits into the outer box, and an inner diameter of the hollow portion of the roll paper extending upward from the base portion. A lower holding member having a rod-like portion having such an outer diameter, and an upper holding member having an outer shape in which a concave portion having an inner diameter matching the outer diameter of the roll paper is formed and fitted into the outer box; The lower holding member is installed in the outer box with the rod-shaped portion facing upward, and the upper holding member faces the outer portion above the lower holding member with the concave portion facing downward. It is installed in a box.

  According to this configuration, first, since the base portion and the upper holding member of the lower holding member have an outer shape that fits in the outer box, the lower holding member and the upper holding member are in the outer box. When installed, it is fitted and fixed in the outer box. Thus, the rod-shaped portion extends upward from the base portion of the lower holding member fitted and fixed in the outer box, and this rod-shaped portion has an outer diameter that matches the inner diameter of the hollow portion of the roll paper. is doing. For this reason, roll paper can be hold | maintained in an outer box by accommodating roll paper in an outer box so that a rod-shaped part may be inserted in a hollow part. In the outer box, an upper holding member having a recess having an inner diameter that matches the outer diameter of the roll paper is fitted and fixed above the lower holding member. For this reason, by inserting the upper end of the roll paper held by the lower holding member into the recess of the upper holding member, it is possible to prevent the upper end of the roll paper from swinging around the lower end. As described above, since the hollow portion of the roll paper is held by the rod-like portion of the lower holding member and it is not necessary to hold the outer peripheral surface of the roll paper, the size of the lower holding member can be reduced. The upper holding member holds the outer peripheral surface of the roll paper. As described above, the lower holding member holds the hollow portion of the roll paper, and the upper holding member only prevents the roll paper from swinging. Therefore, it is not necessary to increase the size. As a result, the coreless roll paper can be held while maintaining the transportation cost. The concave portion of the upper holding member may be formed as a through hole. In addition, the “outer diameter that matches the inner diameter of the hollow portion of the roll paper” of the rod-shaped portion is not necessarily the same as the outer diameter of the rod-shaped portion and the inner diameter of the hollow portion. The difference between the outer diameter and the inner diameter of the hollow portion may be ± 0.3 to 1, preferably 0.3 to 0.5 mm. . Further, the “inner diameter that matches the outer diameter of the roll paper” of the concave portion of the upper holding member does not have to be the same size as the concave portion of the upper holding member and the outer diameter of the roll paper. The difference between the inner diameter of the concave portion of the member and the outer diameter of the roll paper may be within ± 0.3 to 1, preferably 0.3 to 0.5 mm.

  The packing structure can take various configurations. For example, the lower holding member has a base part and a bar-like part formed separately, and the base part matches the outer diameter of the bar-like part. It is preferable that a recess having such an inner diameter is formed, and that one end of the rod-like portion is inserted into the recess. Thus, the lower holding member can be easily formed by forming the base portion and the rod-like portion separately.

  In addition, it is preferable to further include a shock absorbing sheet that is disposed so as to cover the concave portion of the upper holding member. In this manner, by arranging the buffer sheet so as to cover the concave portion of the upper holding member, when the upper end portion of the roll paper is inserted into the concave portion of the upper holding member, the buffer sheet is interposed between the roll paper and the concave portion. Therefore, even if an impact is applied to the outer box, the impact on the roll paper can be reduced.

  Moreover, you may further provide the storage box installed so that it might fit in an outer case above the said upper holding member. For example, an ink ribbon or the like can be stored in the storage box. Normally, when the outer box falls, it falls first from the bottom surface, so the greatest impact is applied to the lower part of the outer box. However, since the storage box is installed in the upper part of the outer box, it is less affected by the impact at the time of dropping and can protect an ink ribbon or the like that is vulnerable to the impact from the impact.

  Moreover, it is preferable that the said storage box has a box main-body part for accommodating a to-be-contained object, and the blade | wing part which protruded outward from the side surface of the said box main-body part. In this way, the box main body portion in which the items to be stored are stored is installed in the outer box via the wing portion. Therefore, when an impact is applied to the outer box, the wing portion absorbs the impact, It is possible to reliably protect the box main body portion in which things are stored from impact.

  Moreover, it is preferable to further include a packaging sheet for packaging the article to be stored, and the packaging sheet is stored in the storage box in a state where the remaining part of the article to be packed is rolled up. Thus, by wrapping a to-be-contained object with a packaging sheet, the to-be-contained object can be reliably protected from an impact. In addition, since the remaining packaging sheet is rolled up and stored in the storage box, the rolled packaging sheet can absorb the impact and more reliably protect the stored item from the impact. it can.

  According to the present invention, it is possible to provide a roll paper packaging structure capable of holding coreless roll paper while maintaining transportation costs.

The storage box 5 is fitted in the outer box 2 by the blade portion 52 in the left-right direction in FIG. 1, and is fitted in the outer box 2 by the box main body portion 51 in the depth direction in FIG. 1. An ink ribbon T is stored in the box body 51 in a state of being wrapped by the packaging sheet 8. More specifically, as shown in FIG. 8, the ink ribbon T includes a supply roll unit T1 and a take-up roll unit T2. A buffer sheet 7 is interposed between the supply roll portion T1 and the take-up roll T2, and the packaging sheet 8 covers the entire ink ribbon T in this state. The packaging sheet 8 is not particularly limited as long as it is a material that can protect the ink ribbon T, but it is preferable to use polyethylene, foamed polyethylene, or the like. A mirror mat can be used as polyethylene, and an air cap (registered trademark) can be used as foamed polyethylene. In addition, the storage box 5 is used for storing the ink ribbon in the present embodiment, but is not limited to storing the ink ribbon in particular, and may store other items.

  Next, a packing method using the above-described roll paper packing structure 1 will be described with reference to the drawings. First, as shown in FIG. 1, the outer box 2 is prepared, and the bottom surface is formed by applying a gummed tape with the flap 21 b closed. Then, the lower holding member 3 is inserted into the outer box 2 so that the rod-shaped portion 32 faces upward, and the lower holding member 3 is pushed in until the lower surface of the base portion 31 contacts the bottom surface of the outer box 2. Thus, when the lower holding member 3 is installed in the outer box 2, the outer shape of the base portion 31 of the lower holding member 3 matches the shape of the bottom surface of the outer box 2. It is fitted and fixed in the box 2.

  Subsequently, the roll paper R is stored in the outer box 2 so that the rod-shaped portion 32 of the lower holding member 3 is inserted into the hollow portion R1 of the roll paper R, and the roll paper R is held by the lower holding member 3. Then, the buffer sheet 7 is placed on the roll paper R fixed to the lower holding member 3, and the upper holding member 4 is placed in the outer box so that the upper end portion of the roll paper R is inserted into the recess 41 from above the buffer sheet 7. Install in 2. Since the outer shape of the upper holding member 4 is substantially the same as the cross-sectional shape of the outer box 2, the upper holding member 4 is fitted and fixed in the outer box 2. Further, since the inner diameter of the concave portion 41 of the upper holding member 4 fitted and fixed in the outer box 2 is substantially the same as the outer diameter of the roll paper R, the roll paper R is the concave portion 41 of the upper holding member 4. It is fitted and fixed inside.

  Subsequently, the ink ribbon T is packaged so as to be covered with the packaging sheet 8 and stored in the box main body 51 of the storage box 5. In this state, the storage box 5 storing the ink ribbon T is stored in the outer box 2, and the storage box 5 is pushed in until the lower surface of the storage box 5 contacts the upper surface of the upper holding member 4. In this state, the storage box 5 is fitted in the outer box 2 by the box body 51 and the four blade parts 52, and is thus fixed in the outer box 2. And the upper surface of the outer box 2 is closed by closing the flap 21a of the outer box 2 and sticking a gum tape finally.

  As described above, according to the present embodiment, first, since the base portion 31 and the upper holding member 4 of the lower holding member 3 have such an outer shape as to fit in the outer box 2, the lower holding member 3. When the upper holding member 4 is installed in the outer box 2, the upper holding member 4 is fitted and fixed in the outer box 2. Thus, the rod-shaped portion 32 extends upward from the base portion 31 of the lower holding member 3 fitted and fixed in the outer box 2, and this rod-shaped portion 32 matches the inner diameter of the hollow portion R 1 of the roll paper R. It has such an outer diameter. For this reason, the roll paper R can be held in the outer box 2 by storing the roll paper R in the outer box 2 so that the rod-like part 32 is inserted into the hollow part R1. In the outer box 2, an upper holding member 4 having a recess 41 having an inner diameter that matches the outer diameter of the roll paper R is fitted and fixed above the lower holding member 3. For this reason, by inserting the upper end of the roll paper R held by the lower holding member 3 into the recess 41 of the upper holding member 4, it is possible to prevent the upper end of the roll paper R from swinging around the lower end. it can. As described above, the roll paper R is held by inserting the rod-like portion 32 of the lower holding member 3 into the hollow portion R1 of the roll paper R, and it is not necessary to hold the outer peripheral surface of the roll paper R. The size of the lower holding member 3 can be reduced. The upper holding member 4 holds the outer peripheral surface of the roll paper R. As described above, the lower holding member 3 holds the roll paper R, and the upper holding member 4 swings the roll paper R. Since it is only necessary to prevent it, it is not necessary to increase its size. As a result, the packaging structure 1 capable of holding the coreless roll paper R while maintaining the transportation cost can be obtained.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to these, A various change is possible unless it deviates from the meaning of this invention. For example, in the above embodiment, the concave portion 41 of the upper holding member 4 is a through hole. However, as shown in FIG. 9, the concave portion 41 may not be a through hole.

  Moreover, in the said embodiment, although the base part 31 and the rod-shaped part 32 are formed as a different body, the lower holding member 3 can also be formed integrally.

  Moreover, in the said embodiment, although the storage box 5 is installed above the upper holding member 4, the storage box 5 can be abbreviate | omitted and the height of the outer box 2 can also be made low by that much.

  Moreover, in the said embodiment, although the lower holding member 3 and the upper holding member 4 have taken the structure which bent the cardboard of 1 sheet, it is not limited to this structure, For example, these holding members 3 and 4 are attached. It can also be set as the structure which is not bent. In this case, for example, the lower holding member 3 preferably has a thickness that can sufficiently hold the rod-like portion 32 in the recess 33.

  In the above embodiment, as a packing method, the lower holding member 3 is installed in the outer box 2 with the rod-shaped part 32 fixed in the recess 33 of the base part 31, and then the roll paper R is put in the outer box. Although housed in 2, other methods can be used. For example, first, only the base portion 31 of the lower holding member 3 is installed in the outer box 2. Then, the rod-shaped portion 32 is inserted into the hollow portion R1 of the roll paper R. Then, the lower end portion of the rod-like portion 32 is protruded from the hollow portion R1 of the roll paper R, and the lower end portion of the protruding rod-like portion 32 is fitted and fixed in the recess 33 of the base portion 31. Can also be stored in the outer box 2.

  In the above embodiment, the packaging sheet 8 only covers the ink ribbon T. For example, as shown in FIG. 10, the ink ribbon T is temporarily covered and the remaining portion is rounded to form the ink ribbon T. It can also be stored in the storage box 5 in a state adjacent to the storage box 5.
