Description

  The present invention relates to a package that protects an object to be packaged from twisting and impact, and particularly to a package that is suitable for packaging an imaging unit including a developing device.

  Conventionally, an imaging unit or the like that contains toner used in an image forming apparatus such as a copying machine or a printer needs to be replaced periodically. Therefore, it is accommodated in a packaging box made of cardboard and transported and stored. Has been done.

These precision parts such as imaging units can be used to transport and store packed items by filling the space between the packed item and the packing box with cushioning material so that the packed item does not rattle inside the packing box. It is common to adopt a packaging form that protects against impacts inside (Patent Document 1).
Utility Model Registration No. 3106011

  By the way, the imaging unit has a long shape in the axial direction in which a rotation shaft such as a developing roller is inserted, and has a structure particularly vulnerable to twisting.

  When such a packaged item is accommodated in the packaging box, the packaged item is securely held in the packaging box so that the packaged item is not twisted in the packaging box. It is desirable to fit resin holding members that fill gaps between the packaging boxes at both ends and press fit into the packaging box.

  However, in order to press-fit the packing object fitted with the holding member into the packing box, the axial length of the packing object fitted with the holding member is determined from the axial inner dimension of the packing box. It is necessary to lengthen the length of the package, and it becomes difficult to accommodate the packaged items in the packaging box.

  Moreover, in order to hold | maintain a to-be-packaged item firmly without twisting in a packaging box, it is necessary to employ | adopt the material with comparatively hard hardness as a material of a holding member.

  However, when a relatively hard material is used for the holding member, there is a problem that the buffering effect is weakened.

  Therefore, the present invention makes it easy to press-fit an object to be packed fitted with a holding member into a packing box, and also maintains a buffering effect even if a hard member is used as the holding member. Is an issue.

  In the present invention, in order to solve the problems as described above, a holding member is fitted to both ends of an object to be packed, and a packaging body including a packing box that accommodates the object to be packed with the holding member fitted therein, Protrusion that presses against the inner surface of the packaging box is provided on the end surface, and a taper portion that serves as an insertion guide is provided at the end of the projection when a packaged object with a holding member fitted therein is accommodated in the packaging box. It is a thing.

  The protrusion on the end face of the holding member can be a protrusion extending in a diagonal direction. Thus, when the protrusion is a protrusion extending in the diagonal direction, press-fitting is possible regardless of which direction the holding member is directed to the packaging box.

  Further, in the packing body in the present invention, an outer box that accommodates the above-described packing box is provided, a buffer member is stored in a space between the outer box and the packing box, and the hardness of the buffer member is set to It can be set to be softer than the hardness.

  Here, the holding member and the buffer member can be formed of a foamed resin. When the holding member and the buffer member are formed of foamed resin in this way, the hardness of the buffer member is made softer than the hardness of the holding member by increasing the foaming magnification of the buffer member relative to the foaming rate of the holding member. Can be set.

  The package of the present invention can be suitably used when the packaged item is an imaging unit including a developing device.

  In the packing body of the present invention, as described above, a protrusion that presses against the inner surface of the packaging box is provided on the end surface of the holding member, and the packaged object in which the holding member is fitted is accommodated in the end of the protrusion in the packing box. In doing so, since the tapered portion serving as the insertion guide is provided, it is easy to press-fit the article to be packed with the holding member fitted therein into the packaging box.

  In addition, an outer box that accommodates the above-described packing box is provided, and a buffer member is stored in a space between the outer box and the packing box, and the hardness of the buffer member is set to be softer than the hardness of the holding member. Even when a hard member is used, an excellent buffering effect can be obtained.
