Description

[Detailed description of the invention] The present invention relates to a folding paper box that is easy to mechanically mass-produce and is pressure-resistant, in which the main body and the lid are made of a series of paper materials so that each part becomes almost double by folding each part. It is something.

Conventionally, paper boxes where the lid is fitted onto the main body have many glued parts such as glue between the main body and the lid, making them unsuitable for mechanical mass production due to assembly, and moreover, the side panels are often single-layered. The drawback was that it had poor pressure resistance.

However, in the present invention, the main body and lid are easily made from a single sheet of paper by punching out the base paper in a single process with a combination of skillful cuts and folds, and almost all the adhesive parts are left intact. The main body and lid are completely connected, and each part is double-layered, so it has excellent pressure resistance and is useful.

Now, to explain in detail about the attached drawing showing an example of the implementation of the present invention, 1 is a flat plate that constitutes a cover plate or a bottom plate, and 3 and 3 have folds 2 and 2 on both sides of the flat plate 1.
5, 5 are outer plates connected to the side edges of the outer plates 3, 3 via folds 4, 4, and 7 is an inner plate connected to the side edge of one inner plate 5. These are inner flat plates that are connected to each other via folds 6. 9 is the other inner plate 5
A flat inscribed piece connected to the side edge of the plate through a fold 8,
Reference numerals 10 and 10 indicate notches made in the flat plate inscribed piece 9, and the plate 5 is slightly located on the inner side of the continuous fold 8 of the flat plate inscribed piece 9.
Shape cut into. 11, 11 are protrusions provided on the side end of the inner flat plate 7, and the notches 10, 10
It is constructed relative to. Reference numerals 13 and 13 indicate another pair of side plates connected to the front and rear of the flat plate 1 via folds 12, 12, and 15 and 15 indicate the side plates 13,
This is a fold-in piece that is connected to both sides of 13 with folds 14, 14 interposed therebetween. The lid component plate A and the main body component plate B, which have the same unfolded shape as described above, are arranged in series so as to be line symmetrical at the side end fold 20 of the side plate 13.

When assembling this, folds 12, 12
In this step, the side plates 13, 13 are erected from the flat plate 1,
The outer and inner side plates 3, 5 are bent so as to wrap around the folded pieces 15, 15 on both sides of the side plates 13, 13, and the protrusions 11, 11 on the side ends of the inner flat plate 7 are inserted into the notches 10, 10 of the flat plate inscribed piece 9. The lid is inserted and locked, and the continuous lid and main body of the same form are folded and completed. 30
is a separately installed rectangular cylindrical four side plate inscribed plate, which has a height twice the inner height of one of the paper boxes, and is inserted and adhered to the inner surface of the four side plates 3, 3, 13, and 13 of the main body. It is something. Incidentally, reference numeral 17 denotes an inner plate connected to one of the side plates 13, which is folded inward and attached to the side plate 13, but this should be attached in a continuous manner as necessary.
