Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvements in packaging materials for toilet bowls.

[0002]

2. Description of the Related Art Conventionally, when transporting a toilet bowl, a bottom plate is laid on the bottom side of the toilet bowl, a cardboard main body is covered from above, and a PP band is wound around the outer circumference of the cardboard body and the bottom plate and packed. In the conventional case, when the PP band is fastened, the lower end of the cardboard body is crushed due to the PP band being fastened.
There is a problem that the winding tightening strength of the PP band is weakened, and when a plurality of vertically packed products are stacked in a packed state, the lower end of the cardboard body is crushed by the stacking and the strength as a packing material is weakened. There was a problem.

[0003]

SUMMARY OF THE INVENTION The present invention has been devised in view of the above-mentioned problems of the prior art. It prevents the lower end portion of the cardboard body from being crushed, secures the PP band winding strength, and loads the PP band. The purpose of the present invention is not to provide a packaging material for a toilet bowl that can improve strength. A packing material obtained by winding and tightening a band, wherein a positioning opening into which a fitting protrusion protruding from the bottom plate is fitted is formed at a lower end portion of the cardboard body, and the positioning opening is A notch for inserting the PP band is formed in the substantially central portion, the notch opening to the lower edge of the cardboard body.

[0004]

In the positioning opening formed at the lower end portion of the cardboard body, the fitting protrusion protruding from the bottom plate is fitted to position the bottom plate and the cardboard body. In this state, the PP band is attached to the cardboard body. When the PP band is inserted into the notch when it is wound around the outer periphery of the bottom plate, the PP band is wound in a state of being in direct contact with the bottom plate, and the lower end edge side of the cardboard body may be crushed during the tightening of the PP band. In addition, the lower edge of the cardboard body can be maintained in a vertical state. Therefore, the lower end edge of the cardboard body is less likely to be crushed even when a plurality of sheets are stacked vertically in the packaged state, and the strength at the time of loading can be improved.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective configuration diagram of the toilet bowl in a packed state.
FIG. 4 is an enlarged partial sectional perspective view of a main part. In the figure, the bottom plate 1
The toilet bowl 2 to be transported is placed on the toilet bowl 2. In this state, the box-shaped cardboard main body 3 is covered from above the toilet bowl 2, and the top cover portion 4 integrally formed on the cardboard body 3 so as to be opened and closed is attached to the upper surface of the toilet bowl 2. The cardboard body 3 with respect to the bottom plate 1 by fitting the fitting projection piece 1a projectingly formed on the side surface of the bottom plate 1 into the positioning opening 3a opened at the lower end portion of the cardboard body 3. Is positioned, and in this state, the PP band 5 is wound around the entire outer circumference from the upper surface of the upper cover portion 4 to the bottom surface of the bottom plate 1.

The PP band 5 is also wound around the outer periphery of the cardboard body 3 and the bottom surface of the bottom plate 1 over the entire periphery. In this example, the PP band 5 is tightened in the central portion of the positioning opening 3a of the cardboard body 3. A cutout portion 3b that opens to the lower end edge of the cardboard main body 3 is formed, and the PP band 5 is inserted into this cutout portion 3b so that the PP band 5 directly contacts the bottom surface of the bottom plate 1 and the side surface of the fitting protrusion 1a. PP in the allowed state
The band 5 can be wound tightly, and the lower end edge side of the cardboard main body 3 is not crushed by the PP band 5 unlike the conventional case when the PP band 5 is fastened, and the lower end of the cardboard main body 3 is cut through the notch 3b. It is well retained in a vertically standing state. Therefore, the lower end edge side of the cardboard main body 3 is not crushed by the tightening of the PP band 5 and the PP band 5 can be tightly wound, and the winding strength of the PP band 5 is larger than the conventional one, and the strong packing is achieved. It can be in a state.

In addition, even when a plurality of vertically packed toilet bowls are stacked in such a packed state, since the lower end edge of the cardboard main body 3 is erected vertically, the corrugated cardboard main body 3 is resistant to vertical stress. In the past, the strength at the time of loading could not be sufficiently secured because the lower edge of the cardboard body was crushed by loading, but in this example, the strength at the time of loading was good because the lower edge of the cardboard body 3 was not crushed. Can be improved to.

[0008]

The present invention is a packing material in which a bottom plate is laid on the bottom surface of a toilet bowl, a cardboard body is covered from above the toilet bowl, and a PP band is wound around the outer circumference of the cardboard body and the bottom plate. At the lower end portion of the cardboard main body, there is formed a positioning opening into which the fitting protrusion protruding from the bottom plate is fitted, and at the substantially central portion of the positioning opening, the lower end edge of the cardboard main body is reached. By forming the opening for inserting the PP band, the fitting protrusion protruding from the bottom plate is fitted into the positioning opening formed at the lower end portion of the cardboard main body to form the bottom plate. When the PP band is positioned around the cardboard body and the PP band is wound around the outer circumference of the cardboard body and the bottom plate in this state, the PP band is inserted into the notch so that the PP band De is tightened in a state of direct contact with the bottom plate, the lower end edge of the cardboard body without collapse when wound up the PP bands, the lower edge of the cardboard main body can maintain a vertical state. Therefore, the lower end edge of the cardboard body is less likely to be crushed even when a plurality of sheets are stacked vertically in the packaged state, and the strength at the time of loading can be improved.
