Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a box formed from a single blank plate and having a lid part that can be opened and closed via a hinge fold line.

<Prior Art> Conventionally, this type of box with a lid has an inner plate connected to an inner front plate and an outer plate connected to an outer front plate, as disclosed in Japanese Utility Model Publication No. 46-30619. I folded it and closed the side part,
It was difficult to manufacture because the fixing structure was complicated, such as the adhesion of the adhesive plate at the tip of the outer plate to the inside of the back plate.

Further, there is a drawback that the lid is easily deformed by the force applied when opening and closing the lid.

<Problems to be Solved by the Invention> Therefore, the present invention provides a box with a lid that has a strong lid portion and is easy to manufacture.

<Means for Solving the Problems> The present invention has been made to solve the above problems.
An inner front plate, a bottom plate, a back plate, a top plate, and an outer front plate are successively arranged, and inner plates are provided on both sides of the inner front, middle plates are provided on both sides of the back plate, and outer plates are provided on both sides of the outer front plate. Continuously provided, horizontal hinge fold lines near the top plate of the back plate, cut lines from the positions corresponding to both ends of the hinge fold line on both the outer side plates and the outer front plate, and both the middle side plates to the cut line. A cut-off auxiliary line that communicates is provided to partition the main body and lid,
The inner plate, the middle plate, and the outer plate are sequentially folded, and at least the space between the middle plate and the outer plate is attached.

<Example> The present invention will be described in detail with reference to the drawings.

FIG. 1 is a development plan view, in which the inner front plate (1), the bottom plate (2), the back plate (3), the top plate (4), and the outer front plate (5) are sequentially connected in the vertical direction through fold lines. The inner plates (6) and (6) are provided on both sides of the inner front plate (1), the middle plates (7) and (7) are provided on both sides of the back plate (3), and both sides of the outer front plate (5). The outer plates (8), (8) are connected to each other through a fold line, and project outwardly by a U-shaped cut line on the boundary fold line between the inner front plate (1) and the inner plates (6), (6). Locking piece (9),
(9) is provided. Further, a horizontal hinge fold line (l) is provided near the inner top plate (4) of the back plate (3), and hinge fold lines (l) are provided on the outer plates (8), (8) and the outer front plate (5).
Inside the outer plates (8), (8) from the positions corresponding to both ends of
A perforation line (k) such as a perforation which is inclined downward and is horizontally connected in the outer front plate (5) is provided, and the perforation line (k) is provided on the inner side plates (7) and (7). ), A cutoff line (k ₁ ) is provided from both ends of the hinge fold line (l) as a cutoff assisting line and is divided into a lid portion (A) and a main body portion (B). In the figure, (A ₁ ) and (A ₁ ) are the outer side of the lid, (A ₂ ) is the outer side of the lid, (A ₃ ) and (A ₃ ) are the inner side of the lid, and (A ₄ ) is the back of the lid, (10), (10), (11) and (11) are folding flaps.

To assemble the present invention having the above structure, the inner front plate (1), the bottom plate (2), the back plate (3), the top plate (4), and the outer front plate (5) are formed into a tubular shape along the fold line. Bend the outer front plate (5) to the outside of the inner front plate (1), and fold the flaps (10), (1
0), (11), (11), inner side plates (6), (6), middle side plates (7), (7), outer side plates (8), (8) are bent at right angles and sequentially folded outward. overlapping lid in side _{(A 3), (A 3} )
And the flaps (1) except between the inner plate (6) and (6)
0), (10), (11), (11) and inner plate (6),
(6), inner side plates (6), (10) and middle side plate (7),
(7), middle side plates (7), (7) and outer side plates (8), (8)
Affix each.

The present invention assembled as described above has a cutting line (k) on the side.
And the auxiliary cutting line (k ₁ ) of the inner side plate (7) communicate with each other, and if the cutting line (k) is broken, the lid portion (A) and the main body portion (B) are separated, and the lid portion (A) is a hinge fold line. It can be opened and closed by (l). The lid (A) the top plate (4), the lid-side front (A _2), the lid back (A _4), folding the flap (11), (11),
It is composed of the inside lid part (A ₃ ) (A ₃ ), and the outside lid part (A ₁ ), (A ₁ ), and the locking pieces (9) and (9) are the inside lid part (A ₃ ).
(A ₃ ) There is no need to worry about it opening unexpectedly because it is crimped to the inner surface, and when opening it can be easily opened by pushing up with a box.

In addition, the middle side plates (7) and (7) have auxiliary cutting lines (k ₁ ),
As (k ₁ ), a cut line may be provided instead of a cut line having a partial joint, and the middle side plate (7),
The box can sufficiently retain its shape without being attached between (7) and the inner plates (6) and (6).

<Effect of the Invention> As described above, according to the present invention, the inner plate, the middle plate, and the outer plate are sequentially folded, and the side portions are closed by sticking.
It is easy to manufacture and has a double structure on the side of the lid and a triple structure on the side of the main body, so that the strength is high and the lid does not deform even when pressed with a finger when opening.

Further, even if the lid has a double structure as described above, since the cutoff line of the outer plate communicates with the cutoff line of the outer plate, the cutoff line can be easily broken when opening.
