Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrapping film storage box for storing a wrapping film wrapped in a roll for packaging foods, etc., and pulling out and cutting a required amount of the wrapping film.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 7 and 8, a wrapping film storage box has a box body A having an open top surface and a lid B for opening and closing the top opening of the box body A. And longitudinal ridges (creases) on the upper and lower sides, respectively
It is configured in an elongated rectangular parallelepiped shape including a1, a2, b1, b2.

The box body A has a front plate 1 and a bottom plate 2.
And the rear surface plate 3 and the left and right side surface plates 4 and 4.

On the other hand, the lid B is formed by a front plate 5, an upper plate 6, and both left and right side plates (only one side is shown) 7.
A saw-toothed cutter 8 for cutting a film is attached to the lower end of the.

In the lid B, the rear end of the upper plate 6 is continuous with the upper end of the rear face plate 3 of the box main body A at the rear upper ridge line b1, and the rear upper ridge line b1 serves as an opening / closing fulcrum of the lid B. .

[0006]

However, according to this conventional storage box, since the opening / closing fulcrum of the lid B is on the rear upper ridge line b1, the front portion of the ridge line b1 must be pressed with a finger to remove the lid B. The closing force does not work. In other words, in order to obtain a strong lid closing force, it is necessary to press the lid B as much as possible in the front part.

On the other hand, when the film is pulled out and cut, for example, in the case of a right-handed person, normally, as shown by the solid line in FIG. The upper plate 7 is pressed to close the lid B, the film F is pulled obliquely upward and pressed against the cutter 8 to cut from one end side.

In this case, according to the conventional storage box, the lid closing force is insufficient only by pressing the upper plate 6 of the lid B in the lid closing / cutting step, and the front plate 5 is pulled by the film pulling force.
Is pushed up and becomes a half-open state.

Therefore, the film F for the cutter 8 is
The film F was not cut smoothly due to insufficient adhesion, and the film F was wrinkled or half-cut.

On the other hand, in order to prevent this, in order to obtain a sufficient lid closing force, at the above-mentioned step, the box should be held again so that the thumbs may hit the lid front plate 5 as shown by phantom lines in FIG. It must be done, and the operation becomes troublesome.

Therefore, the present invention provides a wrapping film storage box which can obtain a sufficient lid closing force without the need to re-hold the film at the time of cutting and can cut the film smoothly.

[0012]

According to a first aspect of the present invention, there is provided a box main body having an opened upper surface for accommodating a wrap film wound in a roll shape, and a lid for opening and closing the upper opening of the box main body. The box body is formed in a rectangular parallelepiped shape having lengthwise ridgelines on the front and bottom sides and the rear and top and bottom sides, and the box body includes a bottom plate, a front plate, a rear plate lower than the front plate, and left and right side plates. The lid is composed of an upper plate, a front plate having a cutter at the lower end, a rear plate, and left and right side plates,
The lower end of the rear plate of the lid and the upper end of the rear plate of the box body are located below the ridgeline of the upper rear side and are continuous via a fold line serving as an opening / closing fulcrum of the lid.

According to a second aspect of the present invention, in the structure of the first aspect, the left and right side plates of the lid are fixed to the left and right ends of the front plate and the rear plate, respectively.

According to a third aspect of the present invention, in the structure of the first or second aspect, guide flaps are formed by bending upward on the wrap film at the upper end of the front plate of the box body, and the left and right ends of the guide flap are formed. It is fixed to the left and right side plates of the box body.

[0015]

According to the above construction, since the opening / closing fulcrum of the lid is below the upper ridgeline on the rear side, compared to the conventional storage box in which the ridgeline serves as the opening / closing fulcrum, even if the same portion is pressed by the principle of leverage, the lid is pressed. The closing force becomes much stronger.

Therefore, even if the box is not held again at the film cutting stage, a sufficient lid closing force can be obtained with the upper plate held down, and the film can be cut smoothly.

Further, according to the structure of claim 2, since the lid has a box structure in which four rounds (front, rear, left, right, and upper side) are closed, as compared with the conventional box in which the rear end sides of both lid side plates are free. , The rigidity of the lid is much higher.

As a result, the deformation of the lid and the cutter in the opening direction due to the film pulling force at the film cutting stage is suppressed, and the lid closed state is reliably maintained, so that the film is cut more smoothly.

Even when the lid closing force is insufficient due to an operation error, the opening deformation of the lid and the cutter is reduced, so that the film can be easily cut.

On the other hand, according to the third aspect of the invention, the guide flap allows the film to be smoothly drawn out without catching on the upper end of the front plate when the film is drawn out, and the film is prevented from jumping out of the box due to the pulling force. .

Moreover, since the left and right ends of this guide flap are fixed to the left and right side plates of the box body, even if the pulling force of the film is excessive or the pulling direction is too upward, the flap is directed upward. Deformation is suppressed. For this reason, the desired film jump-out prevention function is surely fulfilled, and the film drawing / cutting work is carried out more smoothly.

[0022]

Embodiments of the present invention will be described with reference to FIGS.

Basic Embodiment (See FIGS. 1 to 4) This storage box is basically composed of a box body C having an open top surface and a lid D for opening and closing the top opening of the box body C as in the conventional case. , And is formed in an elongated rectangular parallelepiped shape having longitudinal ridge lines a1, a2, b1 and b2 on the front upper and lower sides and the rear upper and lower sides, respectively.

The box body C includes a front plate 11 and a bottom plate 12.
And a rear face plate 13 having a lower height than the front face plate 11 and left and right side face plates 14, 14.

A guide flap 15 is formed on the upper end of the front plate 11 of the box main body C so as to be bent over the entire length of the front plate so as to be inclined upwards of the wrap film F, and the guide flap 15 forms the film F. The film is guided in the drawer, and the film F is prevented from jumping out of the box due to the pulling force.

As shown in FIG.
As shown in FIG. 2, the connecting pieces 15a, 15a are bent and formed at right angles, and the connecting pieces 15a, 15a on both sides are formed on the left and right side plates 1.
It is integrally connected to the inner surfaces of 4, 14 by gluing.

By fixing both ends of the guide flap 15 in this way, upward deformation of the guide flap 15 can be suppressed even when the film pulling force is too strong or the pulling direction is too upward when the film is pulled out. . Therefore, the film pop-out preventing action of the flap 15 is surely achieved.

On the other hand, the lid D includes a front plate 16, an upper plate 17,
A rear plate 18 having a height smaller than that of the front plate 16 and left and right side plates 19, 19 are provided, and a cutter 20 for cutting a film is attached to the lower end of the front plate 16.

In the lid D, the lower end of the rear plate 18 is located below the rear upper ridge line b1 and the rear plate 13 of the box body C is formed.
Is continuous with the upper end of the fold d through the fold d
It is the opening and closing fulcrum of.

Further, as shown in FIG. 4, bent pieces 16a, 18a are provided at right angles on the left and right ends of the front plate 16 and the rear plate 18, respectively.

The bent pieces 16a and 18a are fixed to the inner surfaces of the left and right side plates 19 and 19 by gluing with the tips of the bent pieces 16a and 18a abutted (or overlapped), whereby the lid D is It has a box structure with four closed laps.

According to this storage box, since the opening / closing fulcrum of the lid D is located below the rear upper ridge line b1, the same portion is provided by the principle of leverage as compared with the conventional storage box in which the ridge line b1 is the opening / closing fulcrum. Even if it is pressed down, the lid closing force becomes much stronger.

Thus, in the film cutting step,
As shown in FIG. 3, a sufficient lid closing force is obtained only by pressing the upper plate, and there is no possibility that the lid D will be in a half-opened state due to the film pulling force.

Moreover, since the lid D has the box structure as described above, the rigidity (shape retaining force) of the entire lid D is enhanced, so that the deformation of the lid D due to the film pulling force is suppressed at this film cutting stage. .

Due to the synergistic effect of these two points, the film F can be smoothly cut without having to re-hold the box so that the thumbs may hit the front plate 16 as in the conventional case.

Further, since the deformation of the lid D is reduced, even if a cutting operation is performed in a state where the lid D is half opened due to an operation error, the rear end side of the lid side plates is free from the conventional storage box. In comparison, the film F can be easily cut.

By the way, in the above embodiment, the guide flap 15 is provided so as to be inclined inward, but as shown in FIG.
The flap 15 may extend horizontally from the upper end of the front plate.

Further, as shown in FIG. 6, the flap 15 may be double-folded into a U-turn shape.

In this way, since the rigidity of the guide flap 15 is increased, the deformation of the flap 15 at the time of drawing out the film is suppressed, and since the tip of the flap is formed into a round shape by folding, the frictional resistance with the film F is reduced. As a result, the film pull-out operation is smoothly performed.

[0040]

As described above, according to the present invention, the lid is provided with the rear plate, and the lower end of the rear plate is connected to the upper end of the rear plate of the box body through the fold line below the rear upper ridge. As a result, the opening / closing fulcrum of the lid is set lower than the upper ridgeline on the rear side.Therefore, compared to the conventional storage box whose ridgeline serves as the opening / closing fulcrum, the lid closing force does not affect the lid closing force even if the same part is pressed. Become much stronger.

Therefore, even if the box is not held again at the film cutting stage, a sufficient lid closing force can be obtained with the upper plate held down, and the film can be cut smoothly.

Further, according to the invention of claim 2, since the lid is constructed in a box structure in which the four circumferences are closed, the rigidity of the lid is higher than that of the conventional box in which the rear end sides of both side plates of the lid are free. It can be increased significantly.

As a result, the deformation of the lid and the cutter due to the film pulling force at the film cutting stage is suppressed, and the closed state of the lid is reliably maintained, so that the film is cut more smoothly.

Further, even when the lid closing force is insufficient due to an operation error, the opening of the lid and the cutter is reduced, so that the film can be easily cut.

On the other hand, according to the invention of claim 3, the guide flap allows the film to be smoothly drawn out without being caught on the upper end of the front plate when the film is drawn out, and the film is prevented from jumping out of the box due to the pulling force. be able to.

Moreover, since the left and right ends of the guide flap are fixed to the left and right side plates of the box body, the upward deformation of the flap is suppressed even if the film pulling force is excessive or the pulling direction is too upward. To be For this reason, the desired film jump-out prevention function is surely fulfilled, and the film drawing / cutting work is carried out more smoothly.
