Description

  The present invention relates to a roll paper packaging structure.

Conventionally, roll paper is generally used for recording devices such as business printers. When transporting the roll paper, the roll paper is transferred if the roll paper is transported as it is in a cardboard box. It moves in the cardboard box during transportation, and the outer peripheral surface and the edge portion are damaged. For this reason, usually, a holding member is packed together with roll paper in a cardboard box, and the roll paper is held by this holding member so as not to move in the cardboard box. For example, in Patent Document 1, bearing members are installed at both ends of a roll paper having a core, and the roll paper is supported by inserting the bearing portions of the respective bearing members into the core of the roll paper. .
JP-A-7-69341

  However, coreless type roll paper in which the core is omitted is becoming popular due to demands for cost reduction and resource saving. In such a coreless type roll paper, the shaft portion does not have a core and is in a hollow state, and therefore the strength of the shaft portion is lower than that of a roll paper having a core. For this reason, even if the bearing portion of the bearing member is inserted into the shaft portion of the coreless type roll paper by the above-described method, there is a problem that the roll paper cannot be sufficiently held due to its low strength.

  Then, this invention makes it a subject to provide the packing structure of roll paper which can be reliably hold | maintained even if it is roll paper which does not have a winding core.

A roll paper packaging structure according to the present invention is made to solve the above-described problems, and is a structure for packaging roll paper that does not have a winding core, and is an outer structure for storing the roll paper. A lower holding member and an upper holding member having a box and a recess having an inner diameter that matches the outer diameter of the roll paper, and having an outer shape that fits into the outer box, the lower holding member Is installed in the outer box with the recess facing upward, and the upper holding member is installed in the outer box above the lower holding member with the recess facing downward , At least one of the lower holding member and the upper holding member has an outer shape such that a space is formed between the recess and the inner wall surface of the outer box .

  According to this configuration, since the lower holding member and the upper holding member have an outer shape that fits in the outer box, when installed in the outer box, the lower holding member and the upper holding member are fitted and fixed in the outer box. . In addition, the lower holding member and the upper holding member are formed with recesses having an inner diameter that matches the outer shape of the roll paper. And the lower holding member and the upper holding member are installed in the outer box so that the respective concave portions face each other. For this reason, while the lower end part of roll paper is fitted and hold | maintained in the recessed part of a lower holding member, the upper end part of roll paper can be fitted and hold | maintained in the recessed part of an upper holding member. As described above, since the outer peripheral surface of the roll paper can be held by the lower holding member and the upper holding member that are fitted and fixed in the outer box, even the roll paper that does not have the core is surely provided. Can be held. The “inner diameter that matches the outer diameter of the roll paper” does not have to be the same size as the outer diameter of the roll paper and the inner diameter of the recess, and when the roll paper is inserted into the recess, Any size may be used as long as the roll paper is firmly held by the recess. For example, the inner diameter of the concave portion of each holding member can be larger than the outer diameter of the roll paper by about 1 to 2 mm, preferably about 1 to 1.5 mm. In addition, when holding each end of the roll paper by the concave portion of each holding member, a buffer sheet or the like may be interposed between the concave portion and the roll paper. In this case, the concave portion is interposed via the buffer sheet. It is sufficient that the roll paper has a size that can hold the roll paper firmly.

In addition, by providing a space between the holding member and the inner wall surface of the outer box as described above, even if an impact is applied due to dropping or the like, the space absorbs the impact and reduces the impact on the roll paper. Can do.

  Further, at least one of the lower holding member and the upper receiving member is laminated on the base portion and the base portion formed so as to be fitted in the outer box, and a second through hole is formed. In addition, a plate-like second holding part having an outer shape that defines a space part with the inner wall surface of the outer box, and the first through hole are formed on the second holding part. And a plate-like first holding part having an outer shape that defines a space part with the inner wall surface of the outer box, and the first holding part and the second holding part are The sides are at least partially connected, and the first holding part and the base part are at least partly connected to the other side opposite to the one side, and the recess includes the first and the first parts. It is preferable that it is comprised by 2 through-holes.

  Thus, since the other side of the 1st holding part is connected to the base part via the 2nd holding part, the 1st holding part can move moderately with respect to the base part. For this reason, it becomes possible to respond flexibly to shaking during conveyance, and the impact on the roll paper can be further alleviated.

  Moreover, it is preferable to further include a buffer sheet for reducing impact, which is disposed so as to cover at least one concave portion of the lower holding member and the upper holding member. In this way, by arranging the buffer sheet so as to cover the concave portion of the holding member, when the roll paper is fitted in the concave portion, the buffer sheet is interposed between the roll paper and the concave portion. The impact on the roll paper can be further alleviated.

  In addition, a storage box installed so as to fit in the outer box may be further provided above the 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 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.

  ADVANTAGE OF THE INVENTION According to this invention, even if it is roll paper which does not have a core, the packing structure of roll paper which can be hold | maintained reliably can be provided.

  Hereinafter, embodiments of a packaging structure according to the present invention will be described with reference to the drawings.
