Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a one-touch bottom assembly type packaging container for packaging a cylindrical object such as a photosensitive drum while stably supporting it.

[0002]

[Prior Art]

 Conventionally, when packaging a cylindrical object such as a photosensitive drum, as shown in FIG. 7, the support members 4 are fitted to the inner diameters of both ends of the cylindrical (photosensitive member) 5 and are housed in the outer box 1. Method (2 is a lid flap, 3 is a bottom flap), or, as shown in FIG. 8, the bottom flap 3 and the lid flap 2 of the outer box 1 are extended and bent, and inserted into the inner diameter of the cylinder 5 to support the cylinder 5. The way to do is taken.

[0003]

[Problems to be solved by the device]

 However, in the former method of packing the conventional tubular contents, the support member 4 is a separate component and the bottom flap 3 of the packaging box 1 is assembled by folding the packaging box 1 in the former method. It is possible to use a one-touch bottom assembly method in which the bottom flap 3 is formed simply by opening the bottom flap, but after that it takes time and effort to insert the support member 4 into the bottom. Further, in the latter method, the packaging box 1 and the support portion 6 for the contents can be integrated, but there is a problem that the one-touch bottom assembly method cannot be adopted for the packaging box 1.

In view of the above, the present invention solves the above-mentioned conventional problems, and a packaging having a simple structure in which the packaging box and the supporting portion of the contents are integrated, and the supporting portion can be formed by a one-touch bottom assembly method. The challenge is to provide containers.

[0005]

[Means for Solving the Problems]

 The gist of the present invention is to provide a cardboard packaging container for packaging tubular contents, which is at least square and has a body and flaps that form a lid and a bottom of the body. Alternatively, a content supporting portion for supporting the content is integrally provided at the tip of the flap of the lid portion or both of them, and the flap is folded inward to crush the body portion. It is preserved in a state, and the flap and the support portion are raised at the same time when the body portion is opened to be in a usable state.

[0006]

[Action]

 Therefore, when storing it in a flat plate state in which the body is crushed and opening this body to the original container shape, the flap and the content support provided at the tip of this flap stand up and the bottom part is opened. (Or the lid portion or both) and the supporting portion are formed in a direction orthogonal to the supporting portion and the supporting portion is formed into a usable shape. That is, the one-touch bottom assembly method is possible without providing a separate member.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an exploded view of the packaging container. In the figure, the body flaps 3a, 3b, 3c and 3d are attached to the lid flaps 2a, 2b, 2c and 2d, and the body joint portions 5a and 5b of 4 are attached. 5c and 5d bottom flaps and 6a and 6b bottom flap joints are provided. The lid flaps 2a to 2d include 1a, 1b, 1c and 1d, and the bottom flaps 5a to 5d include 7a, 7b and 7c. , 7d, 7e, 7f, 7g, 7h are provided respectively. In addition, the two-dot chain line indicates a folding line (folding line), and 8a to 8d, 9a to 9d, 10a to 10d, 11a to 11d, 13a to 13d, 14a to 14d, and 12a and 12b are all valleys. After folding, the back side of the shaded part is the joint part.

In the packaging container of the above developed view, the folding lines 11a to 11d are folded back and the bottom flaps 5a to 5d are stacked on the body portions 3a to 3d. Next, the body portions 3a and 3d are folded back 180 degrees along the folding lines 10b and 10d, and the body joint portion 4 (the back side thereof) and the right end side portion of the body portion 3d are joined together with an adhesive or the like, and at the same time, the bottom flap joint is joined. The parts 6a and 6b (on the back surface side thereof) and the bottom flaps 5b and 5d adjacent to the parts 6a and 6b are connected to each other with an adhesive agent, etc. However, before this connection, all the fold lines should be scored by valley folds as described above. deep. When the packaging container is not used, it can be saved in the form shown in the figure, which contributes to space saving.

When this packaging container is used, when the body portions 3a to 3d are opened so that the respective angles are 90 degrees, the bottom flaps 5a to 5d form the bottom surface as shown in FIG. At the same time, the content support portions 7a to 7h are assembled and formed into a substantially cross shape in the direction perpendicular to the bottom surface.

Therefore, after accommodating the photoconductor drum or the like, the lid flaps 2b and 2d are first folded, and then the lid flaps 2a and 2c are further folded so that the content support portions 1a and 1c are attached to the lid flaps 2b and 2d. Insert into slip to form lid.

Although the packaging container has a quadrangular shape in this embodiment, it is not limited to this and may have a polygonal shape as shown in FIG.

Further, as shown in FIG. 5, the mechanism used for the bottom portion in this embodiment may be provided in the lid portion and the opening 20 may be provided at a predetermined position in the body portion. In this case, a method of sealing the opening 20 with tape or the like after storing the contents may be considered.

Further, by applying the cross-shaped contents supporting portions 7a to 7h of this embodiment, as shown in FIG. 6, a method of using the contents supporting portion 21 as a partition of contents can be considered. ..

[0014]

[Effect of the device]

 As described above, according to the present invention, a support portion for supporting contents is integrally provided at the tip of the flap, and when the body portion is flattened, the body portion is opened and the flap and the support portion are simultaneously supported. Since the part is configured to stand up and be used, it is possible to adopt a one-touch bottom assembly method in which it can be used with one touch without separately providing a supporting member, while simplifying the material and reducing the number of assembly steps. It has the effect of enabling reductions.
