Description

Lid cover and roll body storage device of the cylinder body storage box {LID COVER FOR ROLLED CYLINDER STORAGE BOX AND ROLLED CYLINDER STORAGE DEVICE}

The present invention relates to a lid cover and a cylindrical body storage device of a cylindrical body storage box for storing a cylindrical body wound around a film such as a wrap film for food packaging, an aluminum foil, or a cooking paper.

Films, such as a wrap film for food packaging, an aluminum foil, and a cooking paper, are accommodated in the paper roll body storage box made of paper, and are used in the state wound normally in the paper roll body (refer patent document 1). As shown in FIG. 11, the whole cylinder body storage box 100 is formed in the rectangular parallelepiped shape normally, and the cover 102 which closes the rectangular shape container 101 which the upper surface opened, and the opening upper surface of the said container 101 is closed. ) The lid 102 has an upper surface portion 103, a front surface portion 104, and side surface portions 105 on both sides in the longitudinal direction, and a rear short side 103a of the upper surface portion 103 is connected to the container 101. . The cover 102 can rotate the rear short side 103a about the axis, and can open and close the upper surface of the opening of the container 101. The lower edge part of the front part 104 is provided with the cutting edge 106 which cuts a film.

When using the film of the cylinder body storage box 100, the cover 102 is opened, the film 108 of the cylinder body 107 is pulled out a required amount, the cover 102 is closed, and the film 108 is tensioned. The film 108 is cut into the desired length by the cutting edge 106 of the front part 104.

By the way, since the film 108 is wound around 5 m-50 m, for example in the winding body 107, cutting of the film 108 is normally performed many times until the film 108 is used up. . For this reason, the front part 104 and the upper surface part 103 of the cover 102 to which load is applied may be deformed every time the film 108 is cut | disconnected. In particular, since the cylinder body storage box 100 is often used in a humid place such as a kitchen, it is easy to absorb moisture and deform. When the cover 102 with the cutting edge 106 is deformed, the cutting of the film 108 is not appropriately performed, and the film 108 may be torn. Moreover, since the finger | toe is not easily caught by the cylinder body storage box 100, it is difficult to open and close the cover 102, and the film 108 is brought into contact with the cutting blade 106 by pulling out the film 108 without opening the cover 102 securely. 108 may be torn, or the film 108 may be rewound to the cylindrical body 107 by cutting the film 108 without reliably closing the lid 102, which makes it difficult to use.

Then, the cover reinforcement cover which covers a cover is proposed in order to prevent the deformation | transformation of the cover of a cylindrical body storage box (refer patent document 2). This lid reinforcement cover is attached to the surface of the lid of the cylindrical body storage box, and a lid is opened and closed by rotating by the lid reinforcement cover. In this opening and closing, the cover reinforcement cover needs to hold the lid of the cylindrical body storage box, but this holding forms a tongue-like elastic body on the side of the lid reinforcement cover, It is implemented by pressing to the side part.

However, as described above, when the tongue-like elastic body of the lid reinforcement cover is pressed and held on the side surface of the lid, the side surface portion of the lid is also pressed to the side surface of the inner container, and the side surface portion of the lid is sandwiched between the tongue-shaped elastic body and the side surface portion of the container. Will not open well. Moreover, by opening and closing of several covers, the pressing force of a snow-elastic body may weaken gradually, and a cover reinforcement cover may fall from a cover.

This invention is made | formed in view of such a point, The cover of the cylinder body storage box which can open and close the cover of a cylinder body storage box easily, and can prevent it from falling off the cover of a cylinder body storage box even if it opens and closes several times. An object thereof is to provide a cover and a cylinder body storage device.

The present invention for achieving the above object is a lid cover that can be attached to or detached from a lid of a cylindrical body storage box for storing a wound body in which a film is wound, a top plate covering an upper surface portion of the lid, and a front plate covering the front portion of the lid. I) and a pair of side plates covering side surfaces of both sides of the lid, each of the side plates having a locking portion projecting inward from the side plates and hanging on the lower end surface of the lid side surface.

According to the present invention, since the lid is held on the lid cover by hanging the engaging portion of each side plate of the lid cover on the lower end face of the lid, the side portion of the lid is not pressed inward as in the prior art, and the lid is opened. Ease can be improved. Moreover, even if the cover is opened and closed several times, the cover cover can be prevented from falling from the cover.

The said front plate may be provided with the protrusion part which protrudes forward and extends in the left-right direction. In such a case, for example, the cover can be rotated by attaching the thumb to the protrusion, so that the cover can be opened and closed simply with a smaller force.

The center of the protrusion may be recessed. In such a case, for example, the thumb is easily hooked to the protrusion, and the lid can be opened and closed more easily.

The said locking part may have the horizontal upper surface formed along the front-back direction of the said side plate. In this case, the locking portion is preferably caught by the horizontal bottom surface of the side portion of the lid.

The cutting blade which cuts a film may be formed in the lower end part of the said electric board. In such a case, the lid cover can also be used for the simple winding body storage box in which the cutting blade is not attached.

The cutting blade may be formed on a part of the lower end of the front plate. In such a case, since only the scratch which becomes a starting point at the time of cutting | disconnection is formed in a film by a cutting blade, the cut by the propagation of a film can be realized. In such a case, since the notch does not enter the cut end surface of a film, the longitudinal tearing of a film can be suppressed.

The cutting blade may be formed by forming irregularities on the rear surface of the lower end of the front plate. In such a case, for example, it is possible to suppress the finger from touching the cutting blade at the time of use. Moreover, even if a finger touches a cutting blade, injuries can be suppressed.

The said front plate may be provided with the blade cover which covers the cutting blade of a cover. In such a case, for example, it is possible to prevent the finger from touching the cutting edge of the lid during use.

Each said side plate may extend below the said latching | locking part. In this case, the cylindrical body storage box can be stably vertically (left side upright). In addition, each side plate may extend downward from the bottom surface of the said cylindrical body storage box, and in this case, it is more stable to put it vertically, and it puts it horizontally (it puts it in the state which put the top board to the horizontal position). In the case of the case, the bottom surface of the cylinder body storage box is in a state of floating in the air, and even when placed in a place where the temperature becomes high, such as on a microwave oven, heat is not applied to the film inside, and the deterioration of the film can be suppressed. have.

The said front plate may be made into the structure which can be replaced. In such a case, the thing of the shape and pattern which are preferable to a front board can be selected. Moreover, when a front plate has a cutting function of a film, only a part of a front plate can be replaced when cutting performance becomes inferior.

This invention by another viewpoint is a winding body storage apparatus which has a winding body storage box and the cover cover of the above-mentioned cylindrical body storage box which can be attached to the said winding body storage box.

According to the present invention, the lid can easily be opened and closed by the lid cover, and the lid cover can be prevented from falling from the lid of the cylinder body storage box even when the lid is opened and closed several times.

The lid cover 1 is inserted into the lid 102 from the front side so that the lid 22 enters. Thereby, as shown in FIG. 1, the upper surface part 103, the front part 104, and the side part 105 of the cover 102 are covered with the cover cover 1. As shown in FIG. In addition, the cover 102 is fastened to the cover cover 1 by the locking portion 22.

Next, the cover cover 1 is grasped so that the thumb is placed on the protruding portion 21 so that the palm is positioned near the notch 20. As shown in FIG. 5, the cover cover 1 is rotated so as to rotate the cover 102. Is opened. Subsequently, a predetermined amount of the film 108 in the cylindrical body storage box 100 is taken out. Next, the lid 102 is closed by the lid cover 1, and the film 108 is cut into the predetermined length by the cutting blade 106 in a state where the tension is applied to the film 108.

When this film 108 is cut several times and the film 108 disappears from the cylinder body 107, the cover cover 1 falls off from the cover 102. FIG. At this time, the cover cover 1 is placed in front of the cover 102 such that the locking portion 22 of the cover cover 1 is pulled out from the lower side of the lower surface of the side surface 105 of the cover 102 in the reverse direction of the mounting. It is withdrawn to the side and falls. And the cover cover 1 is attached to the cover 102 of the cylinder body storage box 100 after the new film 108 was carried out.

According to the above embodiment, the cover 102 is covered with the cover cover 1 by hanging the locking part 22 of each side plate 12 of the cover cover 1 to the lower end surface of the side surface part 105 of the cover 102. ), The ease of opening of the lid 102 can be improved without being pressed against the side surface portion of the lid as in the prior art. Moreover, even if the cover 102 is opened and closed several times, the cover cover 1 can be prevented from falling from the cover 102.

Since the front plate 11 is provided with a protrusion 21 that protrudes forward and extends in the left and right directions X, the cover cover 1 is rotated by, for example, attaching the thumb to the protrusion 21. You can exercise. For this reason, the cover 102 can be opened and closed simply with a smaller force.

Since the protruding portion 21 is dug in the center, for example, it is easy to put the thumb on the protruding portion 21. In addition, since the thumb is guided to the center of the protruding portion 21, the cover cover 1 can be rotated through the center of the cover cover 1. Therefore, the cover 102 can be opened and closed simply with a smaller force.

Since the locking part 22 has the horizontal upper surface 22a formed along the front-back direction of the side plate 12, the locking part 22 is preferably caught by the horizontal lower end surface of the cover 102 side part 105. As shown in FIG. Moreover, the cover of the cover cover 1 is made by sliding the cover cover 1 in the horizontal direction and taking out the horizontal upper surface 22a of the locking portion 22 below the lower surface of the side surface portion 105 of the cover 102. Desorption to and from 102) can be preferably performed.

In the lid cover 1 described in the above embodiment, as shown in FIG. 6, a cutting blade 30 for cutting the film 108 may be formed at the lower end portion of the front plate 11. In this case, the front plate 11 is formed longer than the lower end of the cover 102 front part 104, and the whole width direction of the film 108 can be cut by the cutting blade 30 of the cover cover 1. Make sure According to this example, the cover cover 1 can also be used for the simple winding body storage box in which the cutting blade is not attached.

Moreover, the cutting blade 30 of the cover cover 1 may attach a metal cutting blade, and as shown in FIG. 7 and FIG. 8, the unevenness 30a is formed on the rear surface 11a of the lower end of the front plate 11. It may be formed by. The unevenness | corrugation 30a is linearly and continuously formed in the lower end part of the front surface 11 back surface 11a. In this case, since the cutting blade 30 is on the back surface 11a, it can be suppressed that the finger touches the cutting blade 30 at the time of use. Moreover, since the cutting blade 30 is uneven | corrugated 30a, even if a finger touches, it can suppress an injury.

Here, the cutting blade 30 of the lid cover 1 may be formed only on a part of the lower end of the front plate 11 as shown in FIG. 9. In this case, the cutting edge 30 can make the starting point of the cutting start of the film 108, can cut the film by the propagation of tearing, and can cut the film 108 with lighter force. Moreover, since it is a cut by electric wave, a notch does not enter the cut end surface of the film 108, and the longitudinal tear of the film 108 can be prevented. In addition, when forming the cutting edge 30 in a part of the lower end of the cover cover 1, for example, when the edge shape of a lower end part is linear or arched (upward convex shape), the cutting edge 30 is formed only in both ends, In addition, in the case of a V shape (downward convex shape), a cutting blade may be formed only at the tip end portion of the V shape center.

In the lid cover 1 described in the above embodiment, as shown in FIG. 10, the blade cover 40 covering the cutting edge 106 of the lid 102 may be formed on the front plate 11. The flexible sheet-like thing which is flexible is used for this day cover 40, for example, and is attached in the vicinity of the lower end part of the front plate 11. As shown in FIG. Usually, the cutting blade 106 is covered, and at the time of cutting the film 10, the cutting blade 106 is bent in accordance with the extraction angle of the film 108. According to this example, it can prevent that a finger touches the cutting edge 106 of the cover 102 at the time of use. In addition, this day cover 40 is not limited to a sheet-like thing, The thing of another structure may be sufficient. For example, the lower end side of the front plate 11 may be extended, the hinge portion may be formed and bent in the middle, and the bent portion may be a blade cover, and the vicinity of the lower end of the front plate 11 may be molded into a thin film that can be bent. The bent portion may be a blade cover.

12, the lower end 23 of each side plate 12 may extend downward from the locking portion 22 to enlarge the side plate 12. In such a case, the step on the side of the cylindrical body storage box 100 when the lid cover 1 is attached is eliminated, and as shown in FIG. 13, the normal storage box 100 can be stably placed vertically. This makes it possible to store even a small place without occupying the place of the kitchen. In addition, in this example, the lower end part 23 of the side plate 12 and the bottom surface 110 of the cylinder body storage box 100 are made to be the same position.

In addition, as shown in FIG. 14, the lower end portion 23 of each side plate 12 may be projected to protrude from the bottom surface 110 of the cylindrical body storage box 100. In this case, it is more stable to vertically hold the cylindrical body storage box 100 to which the cover cover 1 is attached, and when placed horizontally, the bottom surface 110 of the cylindrical body storage box 100 is placed in the air. By being in a floated state, even when placed in a high temperature place such as on a microwave oven, heat is hardly applied to the inner cylindrical body 107, and deterioration of the film can be suppressed. In particular, when the cylindrical body storage box 100 is a wrap film storage box, since heat is hardly applied to the inner wrap film, it is possible to suppress an increase in the output of the wrap film due to heat.

In addition, the front plate 11 of the lid cover 1 may have a structure that can be replaced. In this case, for example, as shown in FIG. 15, the front plate 11 has the front plate main body 50 and the front plate exchange part 51 which can be removed from the said front plate main body 50, for example. The electric plate exchange part 51 is formed in the rectangle containing the lower end part of the electric plate 11, for example, and the electric plate main body 50 is formed in the substantially reverse concave shape used as a remaining part. The front plate main body 50 is provided with protrusions 52 as shown in FIG. 16 along three sides of the inner edge portion thereof, and the front plate exchange portion 51 has three sides (upper surface portion and side portions) of the outer edge portion. Thus, the groove portion 54 to be fitted to the protrusion portion 52 is formed. Therefore, as shown in FIG. 15, the front plate exchange part 51 can be attached or detached with respect to the front plate main body 50 by sliding up and down with respect to the front plate main body 50. As shown in FIG. In this case, the thing of the shape and pattern which are preferable for the front board 11 can be selected. In addition, as shown in FIG. 15, when the cutting blade 30 is in the lower end of the front plate exchange part 51, when the cutting performance becomes inferior, for example, only the front plate exchange part 51 can be replaced. . In addition, a part of the front plate 11 may be replaced as in this example, or the whole of the front plate 11 may be replaced. In addition, the shape of the front plate exchange part 51 (front plate main body 50) may be another shape. In addition, the separation structure does not need to be a sliding type, but may be another structure.
