BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a lid cover and a roll-

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a lid cover for a wrapping film for food packaging, a lid cover for storing a wound body of a film such as an aluminum foil or a cooking paper, and a winding body accommodating device.

Films such as wrap films for food wrapping, aluminum foil, and cooking paper are wrapped in a cylindrical wrapping material and stored in paper wrapping containers made of paper (see Patent Document 1). As shown in Fig. 11, the cylindrical container storage box 100 generally comprises a rectangular parallelepiped container 101, which is formed in a rectangular parallelepiped shape and has an opened upper surface, a lid 102 ). The lid 102 has an upper surface portion 103, a front surface portion 104 and side surfaces 105 on both sides in the longitudinal direction and the rear short side 103a of the upper surface portion 103 is connected to the container 101 . The lid 102 can be rotated around the rear short side 103a to open and close the upper surface of the opening of the container 101. [ At the lower end of the front portion 104, a cutting edge 106 for cutting the film is formed.

When the film of the roll accommodating box 100 is used, the lid 102 is opened to take out a necessary amount of the film 108 of the roll cylinder 107, the lid 102 is closed, and the film 108 is tensioned , The film 108 is cut to a desired length by the cutting edge 106 of the front portion 104. [

Since the film 108 is wound, for example, in the range of 5 m to 50 m in the cylindrical body 107, the film 108 is usually cut many times until the film 108 is used up . Therefore, the front face portion 104 and the top face portion 103 of the lid 102 to which a load is applied may be deformed each time the film 108 is cut. Particularly, the bookbinding storage box 100 is often used in places such as kitchens where moisture is high, so that it absorbs moisture and is liable to be deformed. If the lid 102 with the cutting edge 106 is deformed, the film 108 may not be properly cut and the film 108 may be torn. It is also difficult to open and close the lid 102 because the fingers are not easily caught in the bookcartridge storage box 100 and the film 108 is pulled out without reliably opening the lid 102, The film 108 may be torn or the film 108 may be cut without reliably closing the lid 102 to rewind the film 108 to the roll body 107. This makes the film 108 difficult to use.

In order to prevent deformation of the lid of the roll accommodating box, a lid reinforcing cover for covering the lid is proposed (see Patent Document 2). The lid reinforcing cover is mounted on the surface of the lid of the roll accommodating box and is rotated by the lid reinforcing cover to open and close the lid. It is necessary that the lid reinforcement cover is to hold the lid of the cylinder accommodating box when the lid is opened or closed. This lid is formed by forming a tongue-like elastic body on the side surface of the lid reinforcement cover, And pressing it against the side portion.

Japanese Patent Application Laid-Open No. 2003-160141 Japanese Patent Application Laid-Open No. 2004-352356

However, as described above, when the tongue-like elastic body of the cover reinforcement cover is pressed against the side surface portion of the lid, the side surface portion of the lid is also pressed against the side surface portion of the inner container, the side surface portion of the lid is sandwiched between the elastic body and the side surface portion of the container, Will not open well. Further, by the opening and closing of the cover several times, the pressing force of the tongue-like elastic member gradually weakens, and the cover reinforcement cover may fall from the cover.

SUMMARY OF THE INVENTION The present invention has been made in view of the foregoing points, and it is an object of the present invention to provide a cover for a cylinder storage box which can easily open and close the cover of the cylinder storage box, And an object of the present invention is to provide a cover and a winding cylinder accommodating device.

According to a first aspect of the present invention, there is provided a lid cover detachably mountable on a lid of a cylinder sleeve for accommodating a cylinder in which a film is wound, the lid including an upper plate covering the upper surface of the lid, And a pair of side plates that cover side portions of both sides of the lid, and each of the side plates has a latching portion projecting inward from the side plate and capable of engaging with a lower end surface of the lid side portion.

According to the present invention, since the lid is held by the lid cover by engaging the latching portions of the respective side plates of the lid cover with the lower end surface of the side surface portion of the lid, the side portion of the lid is not pressed inwardly as in the conventional case, The ease of use can be improved. Further, even if the lid is opened and closed many times, it is possible to prevent the lid cover from falling off the lid.

The front plate may be provided with a protrusion protruding forward and extending in the left-right direction. In this case, for example, since the cover cover can be rotated by hanging the thumb on the protruding portion, the cover can be easily opened and closed with a smaller force.

The protruding portion may be centered. In this case, for example, the thumb can be easily attached to the protruding portion, and the cover can be opened and closed more easily.

The retaining portion may have a horizontal upper surface formed along the front-rear direction of the side plate. In this case, the latching portion preferably engages with the horizontal lower end surface of the side surface portion of the lid.

A cutting edge for cutting the film may be formed at the lower end of the front plate. In this case, the lid cover can also be used for a simple cylinder holding box without a cutting blade.

The cutting blade may be formed on a part of the lower end of the front plate. In this case, since only the scratches serving as the starting points at the time of cutting can be formed on the film by the cutting edge, it is possible to realize cut by propagation of the film. In this case, since the notch does not enter the cut end face of the film, longitudinal tearing of the film can be suppressed.

The cutting blade may be formed by forming irregularities on the back surface of the lower end of the front plate. In this case, for example, it is possible to prevent the finger from touching the cutting edge during use. In addition, it is possible to restrain the finger from being injured even if it touches the cutting edge.

The front plate may be provided with a blade cover for covering the cutting edge of the lid. In this case, for example, it is possible to prevent the finger from touching the cutting edge of the cover at the time of use.

Each of the side plates may extend downward from the latching portion. In such a case, the cylinder accommodating box can be stably placed in the vertical direction (the side plate is kept standing upright). Each of the side plates may extend downward from the bottom surface of the container holding box. In such a case, it is more stable to place the container in the vertical direction, and the container is horizontally placed ), The bottom surface of the bookbinding storage box is floated in the air, so that even when placed in a place at a high temperature such as on a microwave oven, heat is not easily applied to the inner film and deterioration of the film can be suppressed have.

The front plate may have a structure that can be exchanged. In this case, it is possible to select a shape or a shape of a desired shape on the front plate. When the front plate has a film cutting function, only the front plate portion can be exchanged when the cutting performance becomes inferior.

A still further aspect of the present invention is a cylinder storage device having a cylinder storage box and a cover cover of the above-described cylinder storage box that can be mounted on the cylinder storage box.

According to the present invention, it is possible to easily open and close the lid of the container holding box by the lid cover, and to prevent the lid cover from falling off from the lid of the container accommodating box even if the lid is opened many times.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view showing a book-cylinder accommodating apparatus A in which a cover 1 is mounted on a book-cylinder accommodating box 100. Fig. Fig. 2 is a perspective view showing a state before the lid cover 1 is mounted on the bookcore storage box 100. Fig.

The lid cover 1 can be freely attached to and detached from the lid 102 of the cylinder storage box 100 as shown in Figs. 1 and 2, for example. The lid cover 1 includes a substantially rectangular upper plate 10 covering the upper surface 103 of the lid 102, a substantially rectangular front plate 11 covering the front surface 104 of the lid 102, And a pair of square side plates 12 covering the side portions 105 on both sides of the side plate 102. As shown in Fig. 3, the rear face side and the bottom face side of the lid cover 1 are open.

An arcuate notch 20 may be formed at the center in the longitudinal direction (lateral direction X) of the rear short side 10a of the upper plate 10 as shown in Figs. The front plate 11 has a shorter length in the vertical direction than the front portion 104 of the lid 102 so that the cutting edge 106 of the lid 102 is exposed. It is preferable that a finger catching portion is formed at the center of the front plate 11 in the left-right direction X. The engaging portion may be the same as the protruding portion 21 that protrudes forward, extends in the left-right direction X, or may be formed with a recess into which the finger is inserted. For example, the projection 21 is formed into a wave shape in a plan view, and a depression 21a is formed at the center of the left and right direction X. The protruding portion 21 may be formed only in the central portion of the front plate 1 or may be formed in the entire lateral direction X. [ The protruding length of the protrusion 21 is preferably 20 mm or less, for example. The shape of the protrusion 21 may be another shape such as an arc shape or a quadrangular shape as viewed from a plane. However, in the case of a wavy shape, opening and closing of the lid 102 can be prevented This is preferable because it can be carried out smoothly.

As shown in Fig. 3, at the lower end of each side plate 12, a latching portion 22 projecting inward is formed. The latching portion 22 protrudes inward from the lower end of the side plate 12 at right angles to the side plate 12 and has a horizontal upper surface 22a formed on the upper surface thereof. The side plate 12 and the latching portion 22 form an L-shape. When the lid cover 1 is mounted on the lid 102, the side surface portion 105 of the lid 102 is disposed on the horizontal upper surface 22a as shown in Fig. When the lid cover 1 is rotated upward, the engaging portion 22 is engaged with the lower end of the side surface portion 105 of the lid 102. As a result, the engaging portion 22 is engaged with the lower end surface of the side surface portion 105 of the lid 102, The side surface portion 105 is lifted and the lid 102 is opened.

The lid cover 1 is formed using a material having a strength higher than that of the roll container storing box 100. The lid cover 1 is formed using, for example, plastic, aluminum or the like, having appropriate rigidity and elasticity, for example. For example, ABS, polystyrene, PC, acrylic resin, polypropylene, polyethylene resin and the like are used. Among them, ABS, polystyrene, PC, acrylic resin and the like which are high rigidity are more preferable. You can. Further, the lid cover 1 may be designed or colored by printing or printing, and may be transparent. In the case of transparency, even if the lid cover 1 is mounted, characters and pictures on the surface of the cylinder accommodating box 100 can be confirmed.

Next, an example of how to use the lid cover 1 configured as described above will be described. 2, the lid cover 1 is disposed on the front side of the bookcore storage box 100 and the lid cover 1 is provided on the lower side of the lower end surface of the side surface portion 105 of the lid 102, The lid cover 1 is inserted into the lid 102 from the front side so that the lid 22 can be inserted. 1, the top surface 103, the front surface portion 104, and the side surface portion 105 of the lid 102 are covered by the lid cover 1. As shown in Fig. The lid 102 is engaged with the lid cover 1 by the latching portion 22.

5, the lid cover 1 is rotated so that the lid 102 is placed in the lid cover 102. Then, as shown in Fig. 5, Is opened. Subsequently, a predetermined amount of the film 108 in the winding cylinder accommodating box 100 is drawn out. Next, the lid 102 is closed by the lid cover 1, and the film 108 is cut to a predetermined length by the cutting edge 106 in the state that the film 108 is tensioned.

When the film 108 is cut several times and the film 108 disappears from the rollers 107, the cover 1 falls off the cover 102. At this time, the lid cover 1 is moved forward from the front side of the lid 102 so that the latching portion 22 of the lid cover 1 is released from the lower side of the lower end surface of the side surface portion 105 of the lid 102, And is dropped. Then, the lid cover 1 is mounted on the lid 102 of the next cylinder storing box 100 with the new film 108 thereon.

According to the embodiment described above, the latching portion 22 of each side plate 12 of the lid cover 1 is hooked on the lower end surface of the side surface portion 105 of the lid 102 so that the lid 102 covers the lid cover 1 It is possible to improve the ease of opening the lid 102 without being pressed against the side surface of the lid as in the prior art. It is also possible to prevent the lid cover 1 from falling off the lid 102 even if the lid 102 is opened or closed many times.

The front plate 11 is provided with the protruding portion 21 protruding frontward and extending in the left and right directions X. For example, when the thumb is hooked on the protruding portion 21 to rotate the cover 1 You can exercise. Therefore, the lid 102 can be easily opened and closed with a smaller force.

Since the projection 21 is centered, the thumb 21 can easily be hooked on the projection 21, for example. Further, since the thumb is guided to the center of the projection 21, the lid cover 1 can be rotated through the center of the lid cover 1. Therefore, the lid 102 can be easily opened and closed with a smaller force.

Since the engaging portion 22 has the horizontal upper surface 22a formed along the front-rear direction of the side plate 12, the engaging portion 22 is preferably engaged with the horizontal lower end surface of the side surface portion 105 of the lid 102. [ The lid cover 1 is slid in the horizontal direction so that the horizontal upper surface 22a of the latching portion 22 is inserted into and disengaged from the lower end surface of the side surface portion 105 of the lid 102, 102 can be preferably attached and detached.

In the lid cover 1 described in the above embodiments, a cutting edge 30 for cutting the film 108 may be formed at the lower end of the front plate 11 as shown in Fig. In this case, the front plate 11 is formed longer than the lower end of the front portion 104 of the lid 102, and the entire width direction of the film 108 can be cut by the cutting edge 30 of the lid cover 1 . According to this example, the lid cover 1 can also be used for a simple cylinder holding box without a cutting blade.

The cutting blade 30 of the lid cover 1 may be provided with a cutting blade made of metal or may be provided with a concavity 30a on the rear surface 11a of the lower end of the front plate 11 as shown in Figs. . The unevenness 30a is formed linearly and continuously on the lower end of the back surface 11a of the front plate 11. In this case, since the cutting edge 30 is on the back surface 11a, it is possible to suppress the finger from touching the cutting edge 30 at the time of use. Further, since the cutting edge 30 is the protrusions 30a, it is possible to restrain the finger 30 from being injured even if it touches the finger.

Here, the cutting edge 30 of the cover 1 may be formed only on a part of the lower end of the front plate 11 as shown in Fig. In this case, the cutting edge 30 makes it possible to make a starting point of starting the cutting of the film 108, cut the film by propagation of the tear, and cut the film 108 with a lighter force. In addition, since the film is cut by radio waves, a notch does not enter the cut end face of the film 108, and longitudinal tearing of the film 108 can be prevented. When the cutting edge 30 is formed in a part of the lower end of the lid cover 1, for example, when the edge of the lower end portion is straight or arcuate (convex upward), the cutting edge 30 is formed only at both ends , Or a V-shaped (downward convex) shape, a cutting edge may be formed only at the tip of the V-shaped center.

A cover 40 for covering the cutting edge 106 of the lid 102 may be formed on the front plate 11 as shown in Fig. The blade cover 40 is, for example, in the form of a flexible flexible sheet, and is mounted near the lower end of the front plate 11. [ Normally, it covers the cutting edge 106, and when the film 10 is cut, it is bent according to the drawing angle of the film 108. According to this example, it is possible to prevent the finger from touching the cutting edge 106 of the lid 102 during use. Further, the blade cover 40 is not limited to a sheet-like one, and may have other configurations. For example, the lower end portion of the front plate 11 may be extended to form a hinge portion so that the bent portion may be a blade cover. Alternatively, a portion near the lower end of the front plate 11 may be formed into a thin, The bent portion may be a blade cover.

12, the lower end 23 of each side plate 12 may be extended downward beyond the latching portion 22 to enlarge the side plate 12. In this case, there is no step on the side of the side of the rolled coil storage box 100 when the lid cover 1 is mounted, and the normal body storage box 100 can be stably placed vertically as shown in Fig. In this way, it is possible to store in a narrow place without taking place of kitchen. In this example, the lower end 23 of the side plate 12 is positioned at the same position as the bottom surface 110 of the container storage box 100.

14, the lower end portions 23 of the side plates 12 may protrude from the bottom surface 110 of the cylinder accommodating box 100. As shown in Fig. In this case, it is more stable to vertically lay the cylinder storage box 100 on which the cover 1 is mounted. When the cylinder storage box 100 is placed horizontally, the bottom surface 110 of the cylinder storage box 100 is in the air By being floated, heat is not easily applied to the inner cylinder 107 even when it is placed at a high temperature such as on a microwave oven, and deterioration of the film can be suppressed. In particular, in the case where the roll paper storage box 100 is a wrap film storage box, heat inside the wrap film can not be applied well, so that rise of the wrap film due to heat can be suppressed.

Further, the front plate 11 of the lid cover 1 may have a structure that can be exchanged. In this case, for example, as shown in Fig. 15, the front plate 11 has, for example, a front plate main body 50 and a front plate replacing portion 51 that can be detached from the front plate main body 50. [ The front plate replacing portion 51 is formed in a square shape including, for example, the lower end portion of the front plate 11, and the front plate main body 50 is formed in a substantially inverted concave shape as the remaining portion. 16 is formed along three sides of the inner edge portion of the front plate main body 50. The front plate replacing portion 51 has three side edges (upper surface portion and side surface portion) of the outer edge portion, A groove portion 54 for fitting the projection portion 52 is formed. Therefore, as shown in Fig. 15, the front plate replacing portion 51 can be attached to and detached from the front plate body 50 by sliding the front plate replacing portion 51 up and down with respect to the front plate body 50. [ In this case, the front plate 11 can be selected in a shape and a shape preferred by the user. 15, when the cutting blade 30 is located at the lower end of the front plate replacing portion 51, only the front plate replacing portion 51 can be replaced when the cutting performance is inferior, for example . Further, as shown in this example, a part of the front plate 11 may be replaced or the entire front plate 11 may be replaced. The shape of the front plate replacing portion 51 (front plate main body 50) may be different. The separation structure is not necessarily a sliding type, but may be a different structure.

While the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to these examples. It will be understood by those skilled in the art that various changes and modifications can be made within the spirit and scope of the appended claims, and it is understood that they fall within the technical scope of the present invention as a matter of course.

For example, the edge shape of the lower end portion of the front plate 11 described in the above embodiments may be a linear shape, an arcuate shape (upward convex shape), a V shape (downward Convex shape) or may be formed to match the shape of the other cutting edges.

The shape of the latching portion 22 may not be a shape protruding in the form of a horizontal plate as in the above embodiment, but may be another shape such as a shape protruding horizontally and curving upward or bending. The present invention is not limited to a wrap film, an aluminum foil, and a cooking paper, but can be applied to a lid cover of a roll accommodating box for accommodating a wound cylindrical body of another film.
