Description

  The present invention relates to a roll storage box wound with a wrap film for food packaging, and more particularly to a storage box that prevents the roll from popping out when the wrap film is pulled out.

  A roll storage box wrapped with a wrapping film for food packaging, for example, includes a bottom plate and a front plate, a rear plate and both side plates erected from each side of the bottom plate as shown in Patent Document 1 below. A storage portion having an upper surface opening, and the roll is stored in the storage portion. Then, a cover plate is continuously provided from the upper edge of the rear plate via a crease line so as to cover the opening of the storage portion, and the cover plate covers the front plate via the crease line. A front plate is provided. The lid front plate is formed with perforations extending over the entire length in the lateral direction, and the lid plate is closed by bonding the lower side of the perforation of the lid front plate and the front plate. .

  And when opening the storage box, the lid front plate below the perforation is pinched by hand, and the lower side of the lid front plate along the perforation (the portion bonded to the front plate) This lid plate can be freely opened and closed by removing the.

  When pulling out the wrap film, the roll around which the film is wound is easily pulled out of the storage section by being pulled by the film. Therefore, in order to prevent the pop-out, the roll is folded into the inner surface of the front plate. Possible reinforcing plates are continuously provided, and fixing pieces are continuously provided at the edges of the reinforcing plates via crease lines. In this way, even when the roll is about to pop out when the film is pulled out, the lower edge of the fixed piece comes into contact with the upper side of the outer peripheral surface of the end of the roll, and the pop-out is prevented.

Japanese Patent No. 4244165

  In the storage box according to Patent Document 1, since the fixed piece is formed on the front plate side (reinforcing plate), the fixed piece prevents the roll from jumping out of the storage portion when the wrap film is pulled out. When doing this, it is easy to apply force to the base side (near the crease line) of the fixed piece. If this force is applied each time the drawer is pulled out, the strength on the base side gradually decreases and the fixed piece does not stand up properly, and the roll pop-out preventing action may be insufficient. In order to prevent this, it is also conceivable to prevent the strength from decreasing by thickening the base side of the fixed piece. However, the size of the storage box is usually small enough to accommodate a roll wrapped with wrap film, etc., and it is usually fixed in the storage box with a thick base. It is often difficult to secure a space for storing the pieces.

  Accordingly, an object of the present invention is to reliably prevent the roll from popping out with a fixed piece provided in the storage box.

  In order to solve the above-described problems, the present invention winds a wrap film or the like around a storage portion of an upper surface opening constituted by a bottom plate and a front plate, a rear plate, and both side plates erected from each side of the bottom plate. In a roll storage box such as a wrap film in which a roll is stored and a lid plate is continuously provided on the upper edge of the rear plate, a reinforcing plate that can be folded on the inner surface of the front plate is provided on the upper edge of the front plate, A first fixing piece extending in the width direction of the reinforcing plate via a crease line is connected to the upper edge of the reinforcing plate, while a connecting piece is connected to the side edge of the rear plate. A second fixed piece extending in the lateral width direction of the rear plate is connected to the upper edge of the installation piece via a crease line, and in a state where the storage box is assembled, the first fixed piece is the second fixed piece. While the second fixed piece stands in the root direction, the second fixed piece stands in the root direction of the first fixed piece, Pieces overlaps one another, the lower edge of the both fixing pieces when said roll is about to jump out has been configured to contact with the end portion outer peripheral surface of the roll.

  In this configuration, since the two fixed pieces of the first fixed piece and the second fixed piece for preventing the roll from jumping out are provided, the contact force from the roll is distributed to both fixed pieces. For this reason, there is a low possibility that force is applied to the base of one fixed piece and the strength of the base is reduced. Moreover, since the first fixed piece and the second fixed piece overlap each other while standing in opposite directions, the two fixed pieces, the front plate, and the continuous piece connected to the front plate constitute triangular pieces. Is in a positional relationship. It is known that this triangular shape is not easily deformed by an external force. Even in this configuration, when the roll comes into contact with both fixed pieces constituting one side of the triangle, the triangular shape is maintained. This roll is prevented from jumping out.

  Moreover, in the said structure, it is preferable to form the direction of the crease line of the continuous piece connected with the said front plate outside the crease line of the said 1st fixed piece in the horizontal width direction.

  The storage box is usually formed using a folding machine in an automated line, and the smaller the number of folding steps in forming, the lower the manufacturing cost. Therefore, when the positional relationship of the crease line is as described above, when the continuous piece is folded inward, the continuous piece pushes the first fixed piece inward, and the first fixed piece is folded. Stand inward along the line of sight. That is, a single process for raising the first fixed piece is not required, and the work process can be simplified.

  Further, in the above configuration in which the first fixed piece is erected by contact with the continuous piece, the tip position of the second fixed piece is the tip of the continuous piece provided with the second fixed piece. It is more preferable that it is deeper in the crease line side of this continuous piece than the position.

  The assembling process of this storage box is a box by sequentially folding the connecting pieces formed on the rear plate and the front plate inward according to the procedure to be described later. Rather than folding the piece by a single process, it is more efficient to fold the piece as the other continuous piece or the like is folded.

  From such a point of view, also in the assembly process of the roll storage box, the second fixed piece continuously provided to the previously-folded continuous piece is supported by the first fixed piece raised by the continuous piece that is folded later. In this case, it is preferable that the first fixed piece is held at the tip of the second fixed piece, and the continuous fixed piece in which the first fixed piece is connected is folded. May not be smooth. Therefore, as described above, by disposing the distal end position of the second fixed piece deeper, when the connecting pieces are folded, the first fixed piece is slightly moved toward the second fixed piece side. It is possible to “escape” and smoothly fold the connecting pieces.

  In addition, since the first fixed piece stands up to some extent (the second fixed piece has an angle at which the second fixed piece can be pushed into the inside), the second fixed piece is raised by the first fixed piece. (Pushing inward) can also be performed smoothly.

  Further, in each of the above configurations, the first fixed piece is sandwiched from the both sides of the continuous piece continuous to the front plate and the continuous piece continuous to the rear plate; More preferably.

  By sandwiching the first fixed piece in this way, the stable standing state at a predetermined angle of the first fixed piece is maintained. Then, when the roll stored in the storage section tries to jump out, the lower edge of the first fixed piece comes into contact with a predetermined position of the roll (generally, on the outer peripheral surface of the end portion) to prevent the roll from popping out. The effect is reliably exhibited.

  According to this invention, the fixed piece which consists of two pieces which opposes in a storage box was formed, and it was made to prevent jumping out of a roll with these both fixed pieces. If it does in this way, the contact force of the roll concerning both fixed pieces will disperse | distribute, and even if it pulls out a film repeatedly, the intensity | strength of the root of this fixed piece will not fall easily. For this reason, the standing state of the fixed piece is maintained, and the roll can be reliably prevented from popping out.
