Description

[Technical Field]

[0001] The present invention relates to a roll storage device for storing a roll of sheet material used as a cutting board, and for pulling out and cutting the sheet material to an appropriate length from the roll. [Background technology]

[0002] Patent Document 1 discloses a wrap film container in which a blunt blade is pressed against a backup member and slid to cut the pulled-out wrap film.

[0003] Furthermore, Patent Document 2 discloses an outer box with a cutter blade that contains a film roll, in which the cutter blade is slidably attached to a guide provided on the lid, and by sliding the cutter blade with the lid closed, the film can be cut to any desired length. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-33937 [Patent Document 2] Japanese Patent Application Laid-Open No. 2008-87852 Summary of the Invention [Problem to be solved by the invention]

[0005] In recent years, rolls of resin sheet material for cutting boards have been sold that are 10 times thicker than plastic wrap. When this roll is stored in the storage container of Patent Document 1, it cannot be cut with a blunt blade, and a sharp blade must be used.

[0006] Furthermore, in Patent Document 2, a sharp cutter blade is attached to the lid, which is dangerous as it can injure fingers when closing the lid.

[0007] Furthermore, in the storage bodies of Patent Documents 1 and 2, the blade is not necessarily positioned at the edge when the lid is closed. If the blade is positioned in the center of the guide, after closing, the blade is first slid to one edge and then moved to the other edge to cut the sheet material.

[0008] When cutting the sheet material halfway in this way, if it becomes impossible to cut it in a straight line, the sheet material must be cut again, which is time-consuming.

[0009] The object of the present invention is to solve the above-mentioned problems and to provide a roll storage device that can easily cut sheet material to any length and safely cut the sheet material in a straight line. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0013] The present invention will be described in detail based on the illustrated embodiment. [Example]

[0014] Fig. 1 is an exploded perspective view of the roll storage device of Example 1, and Fig. 2 is a perspective view of the roll storage device assembled and ready to store a roll R. The roll storage device is made of, for example, a hard synthetic resin, and is a cylindrical body about 30 cm long.

[0015] The roll storage device is composed of a main body 1 that stores a roll R made of sheet material S, for example, a synthetic resin cutting board sheet about 0.5 mm thick, and a lid 2 that is attached to the main body 1 via an axis.

[0016] The shaft portion 3 connecting the main body portion 1 and the lid portion 2 is composed of a plurality of bearing portions 1a provided on the main body portion 1 and a plurality of shaft piece portions 2a provided on the lid portion 2 and corresponding to the bearing portions 1a.

[0017] In addition, the bearing portion 1a and the shaft piece portion 2a may be arranged in reverse with respect to the main body portion 1 and the lid portion 2, and as long as the lid portion 2 is connected to the main body portion 1 so as to be able to be opened and closed freely, an appropriate connecting structure such as a hinge may be adopted.

[0018] On the opposite side of the shaft portion 3 across the gap portion 1b, at the main end edge portion 1c of the main body portion 1 that joins to the lid portion 2, there is arranged a rail portion 1d having a long groove along the longitudinal direction of the roll body storage device, and a sliding portion 1e that can slide left and right on this rail portion 1d.

[0019] As shown in Figure 1, the rail portion 1d can be separated from the main body portion 1, and after the rail portion 1d is assembled as shown in Figure 2 with the sliding portion 1e inserted from the end, the sliding portion 1e will not come off the rail portion 1d.

[0020] Figures 3(a) to (c) are respectively a front view, a side view, and a plan view of the sliding part 1e attached to the rail part 1d. The sliding part 1e has a base part 1f located below the rail part 1d, and a knob part 1h connected to this base part 1f via a cutting part 1g and located above the rail part 1d.

[0021] The cutting portion 1g is composed of a neck portion 1i that connects the base portion 1f and the knob portion 1h, and a pair of blade portions 1j that are attached to the neck portion 1i along the longitudinal direction. As shown in the front view of (a), the cutting edge of the blade portion 1j is diagonal, and as shown in the side view of (b), the blade portion 1j, which is a sharp metal blade thinner than the thickness of the neck portion 1i, is located in the center of the side of the neck portion 1i. The gap between the base portion 1f and the knob portion 1h is narrow, about 5 mm, so the structure is such that fingers cannot come into contact with the blade portion 1j.

[0022] A magnetic sheet material 1k is attached to the bottom surface of the main body 1, and this magnetic sheet material 1k allows the main body 1 to be attached to, for example, the door surface of a refrigerator. Note that the magnetic sheet material 1k does not necessarily have to be attached to the roll storage device.

[0023] The side walls 1l on both sides of the main body 1 along the short side direction perpendicular to the rail 1d have arc-shaped upper edges, and a recessed engaged portion 1m is provided on part of this upper edge. An engaging piece 2b of the lid 2, which will be described later, engages with the engaged portion 1m, thereby maintaining the closed state when the lid 2 is closed.

[0024] The lid portion 2 attached to the main body portion 1 can be opened and closed freely relative to the main body portion 1, and is provided with a long hole portion 2e along the longitudinal direction on the secondary end edge portion 2d of the lid portion 2 that is joined to the main body portion 1 on the opposite side of the shaft portion 3 via the cover portion 2c.

[0025] By lifting the secondary edge portion 2d of the lid portion 2 against the closed state of the lid portion 2, the engagement between the engaging piece 2b and the engaged portion 1m is released, and this release can be done with one hand.

[0026] The elongated hole 2e is provided along the secondary edge 2d and is composed of a pair of main holes 2f through which the knob 1h of the sliding part 1e can pass when the lid 2 is closed, and a secondary hole 2g that connects the pair of main holes 2f and has a groove width narrower than that of the main holes 2f. The knob 1h cannot pass through the secondary hole 2g when the lid 2 is closed.

[0027] The edge portions 2h provided on both sides of the cover portion 2c are arc-shaped concave portions that contact the upper edge of the side wall portion 1l of the main body portion 1, and an engaging piece 2b that engages with the engaged portion 1m of the main body portion 1 is provided near the main hole portion 2f on the secondary edge portion 2d side of this edge portion 2h.

[0028] As shown in Fig. 4, the roll R is set from above in the gap 1b of the assembled roll storage device, and the sheet material S is pulled out by any desired length from the roll R. When the sheet material S is pulled out, the sliding part 1e is positioned at the right end or the left end as shown in the figure.

[0029] After the sheet material S has been pulled out to the length to be cut, the lid 2 is closed with the sliding portion 1e positioned at the end of the rail portion 1d as shown in Fig. 5. Fig. 6 is a cross-sectional side view of the lid 2 in the closed state, in which the engaged portion 1m of the main body 1 and the engaging piece 2b of the lid 2 are engaged, and the sheet material S is clamped between the main edge portion 1c of the main body 1 and the sub-edge portion 2d of the lid 2.

[0030] In this way, the sheet material S is temporarily fixed by clamping it. The sheet material S in this temporarily fixed state can be pulled out further against the temporarily clamped state, and the length of the sheet material S to be pulled out can be adjusted.

[0031] When the lid 2 is closed, only the gripping portion 1h of the sliding portion 1e protrudes from the main hole 2f of the lid 2, and the cutting portion 1g of the sliding portion 1e becomes slidable within the elongated hole 2e. Then, by gripping the gripping portion 1h with the fingers and moving the sliding portion 1e from one main hole 2f to the other main hole 2f in the order shown in the perspective views of Figures 7 and 8, the sheet material S can be cut in a straight line.

[0032] After cutting the sheet material, the sliding portion 1e can be stored in the same position, and when cutting the sheet material S again, the lid portion 2 is opened, the sheet material S is pulled out to the desired length, the lid portion 2 is closed, and the above-mentioned cutting process is performed. [Example]

[0033] Figure 9 is an exploded perspective view of the roll body storage device of Example 2, Figure 10 is a perspective view of the roll body storage device assembled and ready to store the roll body R, and Figure 11 is a side cross-sectional view of the roll body storage device with the lid portion 2 closed.

[0034] The roll storage device of Example 2 also comprises a main body 1 and a lid 2 attached to the main body 1 via a shaft 3. A rail 2i is provided along the longitudinal direction at a main end edge 2d' of the lid 2 that is joined to the main body 1 and is located on the opposite side of the shaft 3 via the cover 2c. A sliding member 2j that is slidable in the left-right direction is disposed on the rail 2i, which has a long groove that extends along the longitudinal direction. After the sliding member 2j is attached to the rail 2i as shown in FIG. 9, the sliding member 2j will not come off the rail 2i.

[0035] Like the sliding portion 1e of Example 1, the sliding portion 2j has a base portion 2k located below the rail portion 2i, and a knob portion 2m connected to this base portion 2k via a cutting portion 2l and fitting into the groove portion of the rail portion 2i.

[0036] Cutting section 2l is composed of neck 2n connecting base 2k and knob 2m, and a pair of blades 2o attached to neck 2n along the longitudinal direction, similar to cutting section 1g in Example 1. The gap between base 2k and knob 2m is narrow, about 5 mm, so fingers cannot come into contact with blades 2o.

[0037] On the opposite side of the shaft portion 3 across the gap portion 1b, at the secondary end edge portion 1c' of the main body portion 1 that joins to the lid portion 2, a secondary rail portion 1p is removably provided, which has a long groove portion 1n that runs along the longitudinal direction of the roll body storage device and a pair of gap portions 1o that do not have grooves and are arranged at both ends of the long groove portion 1n.

[0038] When the lid 2 is closed, the base 2k of the sliding portion 2j can pass through the gap 1o. When the lid 2 is closed, the base 2k cannot pass through the long groove 1n that connects the pair of gaps 1o.

[0039] After the sheet material S is pulled out to the length to be cut from the roll storage device of Example 2 storing the roll R, the lid 2 is closed with the sliding portion 2j positioned at the end of the rail portion 2i.

[0040] Then, by pinching the gripping portion 2m located above the rail portion 2i with the fingers and moving the sliding portion 2j from one gap portion 1o to the other gap portion 1o, the sheet material S can be cut in a straight line, as with the roll body storage device of Example 1.

[0041] In this way, according to the roll storage devices of Examples 1 and 2, the sheet material S can be easily cut to any desired length, and the sheet material S can be safely cut in a straight line without injuring fingers with the sharp blade portion 1j.

[0042] Furthermore, unlike conventional roll storage devices, there is no need to use both hands, which requires grasping the sheet material with one hand and cutting it with the other hand while holding the storage device while applying tension to the sheet material.By using the roll storage device of this embodiment, even when one hand is occupied with work, it is possible to cut the sheet material S with just the other hand.
