Various materials can be adopted as the material for the box body 2 and the lid 3. However, in order to facilitate manufacture, reduce weight, and reduce costs, cardboard,
Plastic cardboard, foamed synthetic resin plate, etc. can be used. Plastic corrugated cardboard is particularly preferred because it enables various sterilizations. In the first embodiment,
This shows an example in which a relatively thick wall, for example, a double-faced cardboard is used.

The box body 2 is configured to be deployable as shown in FIG. 2, and has a rectangular plate-shaped bottom plate 5 and a bottom plate 5.
Each of the side edges has a side plate portion 6 in the form of a rectangular plate, which is bent and connected to a deployed state and an upright state shown in FIG.

[0008] A fixing margin 7 for fixing to the adjacent side plate portion 6b is continuously provided via a bent portion 8 to one side edge in the width direction of the side plate portion 6a at both ends in the longitudinal direction of the bottom plate portion 5. The fixing margin 7 is superimposed on the outer surface of the adjacent side plate portion 6b with each side plate portion 6 standing upright, and is detachably fixed by an appropriate fixing means. Various fixing means can be employed, but in the illustrated example, a magic tape 9 provided on the contact surface between the fixing allowance 7 and the side plate portion 6b is employed.

On the other side in the width direction of the side plate portions 6a at both ends in the longitudinal direction of the bottom plate portion 5, an extraction hole 10 for letting out an article (tube container or the like) inside the box to the outside of the box is formed on the adjacent side plate portion 6c.
An openable / closable door portion 11 is provided through a bent portion 12 so as to be formed at a position along the inner surface of the first side plate portion (hereinafter, referred to as a “first side plate portion”).
An obstruction plate that obstructs the opening and closing of the opening 0 is configured. That is, the closing plate 11 is provided with the side plate portion 6 having the extraction hole 10 formed therein.
It is connected to the side edge of a so as to be freely bent.

[0010] The take-out hole 10 is provided with the opposite side plate portions 6a.
Can be set on either the left or right box support of the content filling machine, but may be formed on only one side plate.

At the middle in the height direction of the side edge of the front end portion (outer end portion in the width direction) of the closing plate 11, a rectangular small insertion piece 14 is continuously provided via a bent portion 13. On the other hand, an insertion portion 15 into which the insertion piece 14 is inserted is formed at an end in the width direction of the first side plate portion 6c. When the box body 2 is made of a relatively thick plate, as shown in the present embodiment, the notch 16 corresponding to the insertion piece 14 is formed at the width direction end of the first side plate 6c. , First side plate portion 6c

FIGS. 4 and 5 show a second embodiment of the present invention. The difference from the first embodiment is that:
The box body is formed of a relatively thin plate material, and the inserted portion 15 formed on the side edge of the first side plate portion 6c is formed by the slit 24 formed along the bent portion 17 of the extension piece 18. This is the point, and other configurations are the same.

FIGS. 6 and 7 show a third embodiment of the present invention. The difference from the second embodiment is that:
The flap 26 is connected to the upper edge of the pair of opposing side plates 6a and 6b of the box body 2. If the upper opening of the box main body 2 can be closed by the flap 26, the lid 3 may not be provided. Since other configurations are the same, the same reference numerals are given and detailed description is omitted.

The present invention is not limited to the above embodiment, and can be appropriately designed and changed. For example, the bottom plate portion can be configured by stacking flaps provided continuously at the lower portions of the respective side plate portions and fixing them detachably. Further, the closing plate can be provided integrally with the side plate portion, the bottom plate portion or the flap.

[0019]

According to the present invention, although the take-out hole for allowing the articles inside the box to flow out to the outside is provided at a position along the inner surface of the first side plate portion, the side plate portion formed with the take-out hole is provided. By supporting the first side plate portion by the continuous closing plate, the first side plate portion can be easily deployed after supply of the articles while preventing the first side plate section from being deployed during the transportation of the articles, and the storage volume is significantly reduced. This can reduce the storage cost, reduce the return cost of the return box, and facilitate reassembly.
