  The packaging cardboard 1 is connected to a rectangular bottom 3 (square in FIG. 1) and two parallel sides 4 and 4 of the bottom 3 in order to assemble a rectangular solid packaging container 2 as shown in FIG. First side wall portions 5 and 5 for forming opposing rectangular side walls, rectangular lid portions 6 and 6 connected to height edges 5a and 5a of the first side wall portions 5 and 5, and the bottom portion Second side wall portions 8 and 8 having the same height as the first side wall portions 5 and 5 for forming opposing rectangular side walls connected to the other two parallel sides 7 and 7, respectively, 2 presser walls 11, 11 that are connected to the height end sides 8 a, 8 a of the side wall parts 8, 8 and that are provided with locking pieces 10, 10 at the end parts 9, 9, and the first side wall parts 5, 5. A rectangular excess corner portion 12 is provided at four locations between the width end sides 5b, 5b and the width end sides 8b, 8b of the second side wall portions 8, 8.

  In the packaging cardboard 1 of FIG. 1, the solid line shown inside the outer shape represents a valley fold when the solidified packaging container 2 is folded, and the alternate long and short dash line represents a mountain fold, and this solid line valley fold And the mountain fold part of a dashed-dotted line is creased beforehand with a press etc.

  Then, as shown in FIG. 2, the packaging cardboard 1 is arranged so that the width end sides 5b, 5b of the first side wall portions 5, 5 and the width end sides 8b, 8b of the second side wall portions 8, 8 are close to each other. When forming a box shape by folding, the excess corner portion 12 is bent so as to protrude outward in a radial diagonal line to form a triangular portion 13 as shown in FIG. 3, and the triangular portion 13 is shown in FIG. As shown in the figure, the presser walls 11 and 11 are folded so as to overlap the outer sides of the second side wall parts 8 and 8 and then connected to the height edges 8a and 8a of the second side wall parts 8 and 8, as shown in FIG. Is folded so as to overlap the triangular portion 13, and then the retaining pieces 10, 10 of the presser walls 11, 11 are inserted and fixed inside the hypotenuse 13a of the inner triangular portion 13 as shown in FIG. Thus, the solidified packaging container 2 of FIG. 7 can be configured.

  At this time, the locking pieces 10 and 10 are bent along the oblique side 13a of the triangular portion 13 and inserted into the triangular portion 13 to be fixed. 11 and 11 are extended from the end portions 9 and 9 at an angle of approximately 45 °.

  Next, the operation of the embodiment shown in FIGS. 1 to 3 will be described.

  In the packaging corrugated cardboard 1 shown in FIG. 1, the width end sides 5 b and 5 b of the first side wall portions 5 and 5 and the width end sides 8 b and 8 b of the second side wall portions 8 and 8 are folded so as to approach each other. When the box-shaped solidified packaging container 2 as shown in FIG. 2 is formed, the surplus corner portion 12 is left over.

  For this reason, the surplus corner portion 12 is bent so as to protrude outward (downward) along the radial diagonal line shown in FIG. 1, thereby forming a triangular portion 13 as shown in FIG. Then, the triangular portion 13 is folded so as to overlap the outside of the second side wall portions 8 and 8. At this time, as shown in FIG. 5, the triangular part 13 having the oblique side 13a corresponding to the locking pieces 10, 10 of the presser walls 11, 11 is folded so as to be inside (the second side wall parts 8, 8 side). fold.

  Next, as shown in FIG. 5, the press walls 11, 11 connected to the height edges 8 a, 8 a of the second side walls 8, 8 are folded so as to overlap the triangular portion 13, and the press walls 11, 11 are folded. The locking pieces 10 are inserted into the oblique side 13a of the inner triangular portion 13 and fixed. As a result, the outer triangular portion 13 is fixed in a state of being clamped by the pressing walls 11, 11 and the inner triangular portion 13. Thereby, the box-shaped solidified packaging container 2 is assembled.

  In order to solidify and package the fluid using the box-shaped solidified packaging container 2 assembled as described above, the lid 6 and 6 are opened as shown in FIG. The fluid 14 is supplied from above so that the inside becomes full. As the fluid 14, various materials can be used as long as they are naturally solidified by being supplied and held in the solidified packaging container 2, for example, supplied to the solidified packaging container 2 and held for a predetermined time. Then, a liquid feed mixture containing molasses that can form a block-like feed can be used.

  As described above, when the solidified packaging container 2 to which the fluid is supplied is allowed to stand for a predetermined time, the fluid is solidified, and a block-shaped solidified product that is filled in the entire interior of the solidified packaging container 2 is manufactured. When the block-shaped solidified product is manufactured, as shown in FIG. 8, when the lid parts 6 and 6 are fixed to each other with a fixing material 15 such as an adhesive tape, the solidified packaging container 2 having the block-shaped solidified product is packaged inside. It can be transported and stored as it is.

  Further, when the block-like solidified product in the solidified packaging container 2 is taken out and used, the fixing member 15 in FIG. 8 is removed, and the locking pieces 10 inserted into the inner side of the oblique side 13a of the inner triangular portion 13; By pulling out 10, the solidified packaging container 2 can be opened as shown in FIG. 1, and the block-shaped solidified product can be easily taken out.

  As described above, a block-shaped solidified product can be produced from a fluid using the solidified packaging container 2, and the solidified packaging container 2 on which the block-shaped solidified product is formed only fixes the lid portions 6 and 6. Therefore, the solidification of the fluid and the packaging of the block-like solidified product can be performed together. Therefore, the production of the block-like solidified product and the packaging operation can be easily performed at low cost.

  Moreover, since there is no unevenness | corrugation inside the folded solidified packaging container 2, the block-shaped solidified material formed in the solidified packaging container 2 can be made into a favorable rectangular shape.

  The present inventors have prepared a liquid feed mixture mainly composed of molasses as a fluid 14 in the solidified packaging container 2 sterically folded by the packaging corrugated cardboard 1 (specific gravity about 1.35 = 1.32-1.39). Value) was filled, and the test which manufactures block-shaped solidified feed was implemented.

  In order to form the block-shaped solidified feed, solidified packaging containers for 10 kg, 5 kg, and 3 kg were prepared, and the fluidized feed mixture was supplied to each test solidified packaging container and solidified. At this time, the solidified packaging container for 10 kg having the largest volume and the largest deformation load on the packaging corrugated cardboard 1 has a vertical dimension of 21.5 cm, a horizontal dimension of 21.5 cm, and a height dimension of 16.5 cm. A thing was used.

  The packaging cardboard 1 must have a deformation strength that does not swell outwardly and deform when filled with a fluid. For this reason, the packaging corrugated cardboard 1 has a corrugated portion. Using a sheet with liners attached to both sides (tops) of the (flute), select the B stage (BF) defined by JISZ1516 (thickness is about 2.5 to 2.8 mm). A packaging cardboard 1 having a thickness of 2.5 mm was used.

  As described above, in the solidified packaging container 2 having a capacity of 10 kg or less using the corrugated cardboard 1 having a thickness of 2.5 mm, the solidified packaging container 2 may be swollen by the fluid filled. The block-shaped solidified feed having a good shape could be produced.

  Here, when the thickness of the packaging cardboard 1 is increased, the deformation strength of the solidified packaging container 2 can be increased. On the other hand, when the thickness of the packaging cardboard 1 is increased, the packaging cardboard 1 is folded. When the solidified packaging container 2 is formed, there is a problem that the folded portion is easily broken, and when the breakage occurs, the fluid filled from the broken portion leaks out.

  However, according to the packaging corrugated cardboard 1 having a thickness of about 2.5 to 2.8 mm, there is no problem of causing damage when the solidified packaging container 2 is formed by folding and can be easily folded. There was found. For this reason, it was found that the packaging corrugated cardboard 1 used for the solidified packaging container 2 is preferable when the solidified packaging container 2 having a maximum thickness of 3 mm and a size capable of maintaining the deformation strength is formed.

  In addition, the solidified packaging container of the fluid of the present invention is not limited to the above embodiment, and may be, for example, a trapezoidal solidified packaging container other than the rectangular shape, and is within the scope not departing from the gist of the present invention. Of course, various changes can be made.
