DETAILED DESCRIPTION OF THE INVENTION

[0009] The wrap storage case A in one embodiment has, for example, a bilaterally symmetrical shape, and as shown in Figures 1 to 6, includes a roll storage container 1 that stores a wrap roll 5, and a lid 2 that is rotatably attached to one side edge of the roll storage container 1 and covers the wrap roll 5 stored in the roll storage container 1. The wrap storage case does not necessarily have to have a symmetrical shape. In addition, the wrap roll stored in the wrap storage case of the present invention is made by wrapping a single-layer or multi-layer wrap film containing a known material containing a resin including one or more thermoplastic resins such as polyvinyl chloride, polyvinylidene chloride, polyethylene, polypropylene, polybutene-1, polymethylpentene-1, and nylon, which are used for food packaging, etc., and the wrap film has a known thickness and width.

[0010] The wrap storage case A has a cutting blade 25 on the lid 2 for cutting the wrap film. The user opens the lid 2 of the wrap storage case A, grasps the end of the wrap film from the wrap roll 5 stored in the roll storage container 1, pulls it out, and then closes the lid 2, allowing the cutter blade 25 to cut the wrap film to the appropriate length for use. The wrap storage case A of this embodiment will be described in detail below. In the following description, the side of the wrap storage case A where the lid 2 is supported is referred to as one side, and the side where the lid 2 is opened is referred to as the other side. Also, the left-right direction when viewed from the other side of the wrap storage case A is referred to as the longitudinal direction.

[0011] The roll storage container 1 constituting the wrap storage case A of this embodiment is made of a resin material such as a polyolefin resin such as polypropylene or polyethylene, ABS resin, polystyrene resin, polyurethane resin, phenolic resin, melamine resin, epoxy resin, urea resin, or polyphenylene sulfide resin, or a resin material obtained by incorporating fibers such as cellulose fibers into these resins, and has a roll storage section 11 that stores the wrap roll 5 in a rotatable manner, and a cutter blade receiving section 12 that is provided continuously on the other side of the roll storage section 11, as shown in Figures 3 and 6.

[0012] The roll storage section 11 of the roll storage container 1 has a bottom wall 11a with an arc-shaped inner surface, a lid support wall 11b extending upward from one side of the bottom wall 11a, and side walls 11c, 11c that close the longitudinal ends of the roll storage section 11.

[0013] 5(b), (d), and 6, the roll storage section 11 has a plurality of ribs 11i, 11i provided along the longitudinal direction in the central portion of the bottom surface of the bottom wall 11a. The roll storage section 11 also has pedestals 11e, 11e provided on the left and right sides of the bottom surface in the longitudinal direction, and plate magnets 15, 15 are attached to the undersides of the pedestals 11e, 11e with double-sided tape or the like.

[0014] The wrap storage case A of this embodiment has a plurality of ribs 11i on the underside of the roll storage section 11, which allows the wrap storage case A to be stably placed on a horizontal surface. In addition, a base 11e is provided on the underside of the roll storage section 11, and plate magnets 15, 15 are attached to the base, so that the wrap storage case A can be attracted to and held on a vertical steel surface such as the wall of a refrigerator. The roll storage section 11 of the wrap storage case A may have a plurality of ribs 11i provided along the entire length of the bottom surface of the bottom wall 11a, and the base section 11e and the plate magnet 15 may not necessarily be provided. When opening the lid 2 with one hand, the thumb is placed on 21e and the other fingers support the bottom side. Rib 11i is provided to prevent the fingers supporting the bottom side from slipping when the thumb is placed on 21e to open the lid. The multiple ribs 11i are provided to allow users to place their fingers on ribs 11i regardless of the size of their hands, thereby further preventing the fingertips from slipping.

[0015] The roll storage section 11 does not need to have an arc-shaped inner surface over the entire inner surface of the bottom wall 11a. For example, if base portions 11e, 11e are provided on the bottom surface protruding downward as shown in Figure 3, ribs 11f having an arc-shaped shape similar to the arc-shaped inner surface of the bottom wall 11a may be provided on the inner side of the base portions 11e, 11e to maintain smooth rotation of the wrap roll 5.

[0016] As shown in FIGS. 2 and 3, the roll storage section 11 is provided with storage section side hinge sections 11g, 11g at a plurality of locations in the longitudinal direction at the upper end of the lid support wall 11b to rotatably support the lid 2.

[0017] As shown in Figure 3, the roll storage section 11 has a hole 11h formed in the side wall 11c, and a support shaft 14b is provided that protrudes toward the inner periphery of the side wall 11c by inserting a shaft member 14 into the hole 11h from the outside on the left and right sides.

[0018] The shaft member 14 has a disk-shaped mounting plate portion 14a and a plurality of arc-shaped walls 14c, 14c protruding from one surface of the mounting plate portion 14a, and the plurality of arc-shaped walls 14c, 14c form a cylindrical support shaft 14b. The arc-shaped walls 14c, 14c of the shaft member 14 have elasticity, and some of the arc-shaped walls 14c have engaging protrusions 14d on their outer circumferential surfaces that protrude in the outer circumferential direction.

[0019] The roll storage section 11 has the support shaft 14b of the shaft member 14 inserted from the outside of the left and right sides of the hole 11h in the side wall 11c against the elasticity of the arc-shaped wall 14c, and the side wall 11c is clamped and attached by the mounting plate portion 14a of the shaft member 14 inserted into the hole 11h and the engaging protrusion portion 14d of the restored arc-shaped wall 14c, so that the support shaft 14b that rotatably supports the wrap roll 5 is provided on the inner side of the side wall 11c.

[0020] The user stores the cylindrical wrap roll 5 by inserting one end of the cylindrical wrap roll 5 through the support shaft 14b while the support shaft 14b is attached to one side wall 11c of the roll storage section 11, and then inserting and attaching the other shaft member 14 from the outside of the side wall 11c, thereby storing and holding the wrap roll 5 in the roll storage section 11 in a freely rotatable manner, as shown in Figure 4.

[0021] As shown in Figure 6(b), the cutting blade receiving portion 12 of the roll storage container 1 has a bottom wall portion 12a that is continuous with the other side end of the bottom wall 11a of the roll storage portion 11 and extends to the other side, an outer wall portion 12b that extends upward from the outer periphery of the bottom wall portion 12a (the side opposite the roll storage portion), and an inner wall portion 12c that extends upward from the inner periphery of the bottom wall portion 12a, forming a cutting blade receiving portion 12d that has a U-shaped cross section and opens upward.

[0022] As shown in Figures 3 and 4, the cutter blade receiving portion 12 has a notch 12e at the center position in the longitudinal direction, where the inner wall portion 12c and the outer wall portion 12b are notched from above, making it easy to grip the end of the wrap film when pulling it out.

[0023] The lid 2 constituting the wrap storage case A of this embodiment is made of a material selected independently from the roll storage container 1, for example from the resin material constituting the roll storage container 1, and as shown in Figures 1 to 6, has an upper wall 21a having an arc-shaped inner surface and covering the roll storage section 11 of the roll storage container 1, a cutting blade holding section 21b continuing to the other side of the upper wall 21a, and side walls 21c, 21c that close the longitudinal ends of the upper wall 21a and the cutting blade holding section 21b. The lid 2 has a knob 21e on the top surface of the top wall 21a, so that the lid 2 can be easily opened and closed with one hand.

[0024] As shown in Figures 2 and 3, the lid 2 has multiple lid-side hinge portions 21d, 21d provided along one side of the upper wall 21a, and the storage section-side hinge portions 11g, 11g and the lid-side hinge portions 21d, 21d of the lid support wall 11b of the roll storage container 1 are pivotally supported around the rotation axis 2a. As shown in Figure 6(a), the rotation axis 2a of the lid side hinge portions 21d, 21d and the storage section side hinge portions 11g, 11g is positioned above the rotation axis 1a of the wrap roll 5, which is the center of the shaft member 14, and the lid 2 is opened and closed by rotating around the rotation axis 2a of the lid side hinge portions 21d, 21d and the storage section side hinge portions 11g, 11g.

[0025] As shown in Figure 6(b), the cutting blade holding portion 21b of the lid 2 has an outer wall portion 21f that extends continuously to the other side from the other end of the upper wall 21a and then curves downward, and a lap holding wall portion 21g that extends downward from the underside of one side of the outer wall portion 21f, and a cutting blade mounting portion 21h that opens downward is formed by the outer wall portion 21f and the lap holding wall portion 21g.

[0026] The cutting blade 25 is formed by attaching a cutting blade body 25a to a cutting blade attachment member 25b, which is an elongated member, and is attached to the lid 2 by, for example, press-fitting the cutting blade attachment member 25b into the cutting blade attachment portion 21h. The cutting blade 25 only needs to have the function of cutting the wrap, and its shape is not limited to a saw blade, etc. The material of the cutting blade 25 can be selected from one or more metal materials such as stainless steel, tinplate, and aluminum, one or more resin materials such as polyester, polyethylene, polypropylene, polystyrene, polyacetal, polylactic acid, polyphenylene sulfide, PEEK (polyether ether ketone), PES (polyethersulfone), and PPS (polyphenylene sulfide), and one or more paper materials such as vulcanized paper, resin-impregnated hardened paper, and abrasive grain-bonded paper. The configuration of the cutting blade 25 and the configuration for attaching the cutting blade 25 to the cutting blade attachment portion 21h of the lid 2 are not limited in any way.

[0027] The lower tip of the cutting blade 25 attached to the cutting blade attachment portion 21h of the lid 2 is located above the lower tip of the outer wall portion 21f and the lower tip of the lap holding wall portion 21g, and the cutting blade 25 does not protrude from below the lid 2.

[0028] When the lid 2 supported by the roll storage container 1 is closed, the inner wall 12c and outer wall 12b of the cutting blade receiving portion 12 fit between the outer wall 21f of the lid 2 and the wrap holding wall 21g, maintaining the closed state.When the lid 2 is in the closed state, the cutting blade body 25a of the cutting blade 25 attached to the cutting blade attachment portion 21h is accommodated in the cutting blade receiving portion 12d of the roll storage container 1.

[0029] The overall structure of the wrap storage case A has been described above, but the wrap storage case A of this embodiment has a structure that allows the wrap film to be pulled out and cut well. The structure for pulling out and cutting the wrap film from the wrap storage case A of this embodiment will be further described.

[0030] - Pulling out and cutting wrap film - As shown in Figures 7 and 8, the wrap storage case A of this embodiment has an anti-slip material 16 provided on the inner surface of the inner wall portion 12c of the cutting blade receiving portion 12, and a joining protrusion 12g provided below the anti-slip material 16.

[0031] The anti-slip material 16 is made of an elastic material such as synthetic rubber and / or a resin material whose inner surface has high friction against the wrap, and is attached in a recess 12f provided on the inner surface of the inner wall portion 12c so that the inner surface of the anti-slip material 16 is flush with the inner surface of the inner wall portion 12c. The anti-slip material 16 may be attached so as to protrude slightly inward from the inner surface of the inner wall portion 12c. 7, the non-slip material 16 may be formed as a single strip on each side of the cutout 12e, or the strips on both sides may be divided into two or more pieces along the length of the wrap storage case, for a total of four pieces. Furthermore, the non-slip material may be formed in the form of multiple dots or any pattern, other than a strip.

[0032] When the lid 2 of the wrap storage case A is in an open state, the user can pull out the wrap film 5a to an appropriate length by, for example, grasping and pulling the tip of the wrap film 5a exposed in the notched portion 12e of the cutting blade receiving portion 12.

[0033] At this time, as shown in Figure 8, an anti-slip material 16 is provided on the inner surface of the inner wall portion 12c of the cutting blade receiving portion 12, and the wrap film 5a pulled out from the wrap roll 5 does not come into contact with the anti-slip material 16 until it reaches the upper end of the inner wall portion 12c, so the wrap film 5a can be pulled out smoothly without resistance. When the user pulls out the wrap film 5a, the wrap film 5a is stretched across the upper ends of the inner wall portion 12c and the outer wall portion 12b of the cutting blade receiving portion 12.

[0034] After the user pulls out the wrap film 5a, the user closes the lid 2 of the wrap storage case A, and as shown in Figure 9, the lower end of the wrap pressing wall 21g of the lid 2 approaches the wrap film 5a from above and the side (one side), and presses the wrap film 5a into contact with the anti-slip material 16 provided on the inner wall 12c before the cutting blade 25 cuts the wrap film 5a.

[0035] As shown in Figures 6(a) and 9, in the wrap storage case A of this embodiment, the rotating shaft 2a that supports the lid 2 so that it can rotate freely is positioned above the rotating shaft 1a of the wrap roll 5, which is the center of the shaft member 14.Therefore, the lower end of the wrap pressing wall portion 21g of the lid 2 approaches the wrap film 5a from above and the side (one side direction), so that even when the inner surface of the inner wall portion 12c is nearly vertical, the wrap film 5a can be reliably pressed against and brought into contact with the anti-slip material 16.

[0036] The wrap film 5a, which is pressed against the lower end of the wrap holding wall 21g of the lid 2 and comes into contact with the anti-slip material 16, is clamped between the wrap holding wall 21g and the anti-slip material 16, and the pulled-out wrap film 5a is in a taut state with tension applied across the inner wall 12c and the outer wall 12b.

[0037] Furthermore, when the user closes the lid 2 of the wrap storage case A, the wrap film 5a stretched between the upper ends of the inner wall portion 12c and the outer wall portion 12b is cut by the cutting blade 25, and the cut wrap film 5a can be pulled out and used freely.

[0038] 10, by further rotating the lid 2 of the wrap storage case A to completely close it, the outer wall 21f of the lid 2 covers the cutting blade receiving portion 12 of the roll storage container 1, and the lower end of the wrap pressing wall 21g is released from the non-slip material 16, and the lid 2 is firmly closed with the cutting blade 25 housed in the cutting blade housing portion 12d. At this time, the lower end of the wrap pressing wall 21g may be joined to a joining protrusion 12g provided on the inner surface of the inner wall 12c as needed.

[0039] When the lid 2 of the wrap storage case A is closed, the lower end of the wrap pressing wall portion 21g of the lid 2 does not abut against the anti-slip material 16, which has elasticity, friction, etc., so deformation and a decrease in friction caused by constant external force being applied to the anti-slip material 16 can be prevented, and the anti-slip function of the wrap film 5a can be maintained for a long period of time.

[0040] -Effects of the wrap storage case of this embodiment- In the wrap storage case A of this embodiment, a cutting blade 25 for cutting the wrap film 5a is provided on the lid 2, and is attached to a cutting blade mounting portion 21h formed between the outer wall portion 21f, which extends downward from the cutting blade 25, and the wrap holding wall portion 21g.Therefore, the cutting blade 25 does not protrude downward, and the wrap film 5a can be cut by the cutting blade 25 without injuring fingers, thereby improving safety.

[0041] In the wrap storage case A of this embodiment, the wrap film 5a is brought into contact with the anti-slip material 16 before being cut by the cutting blade 25 provided on the lid 2, so that tension is applied to the pulled wrap film 5a, ensuring that the cutting blade 25 can be cut at the appropriate position.

[0042] In the wrap storage case A of this embodiment, an anti-slip material 16 that prevents the wrap film 5a from slipping when the wrap film 5a is cut is provided on the inner surface of the inner wall portion 12c of the cutting blade receiving portion 12. Therefore, when the wrap film 5a is pulled out, the wrap film 5a is prevented from coming into contact with the anti-slip material 16, allowing the wrap film 5a to be pulled out smoothly, improving operability.

[0043] In the wrap storage case A of this embodiment, an anti-slip material 16 is attached to the inner surface of the inner wall portion 12c of the cutter blade receiving portion 12, but the angle of the inner surface at which the anti-slip material 16 is attached or the height position at which the anti-slip material 16 is attached are not particularly limited, and it is sufficient that the anti-slip material 16 is arranged so that the wrap film 5a pulled out from the wrap roll 5 does not come into contact with the anti-slip material 16 on the way to the upper end of the inner wall portion 12c, that is, so that the anti-slip material 16 does not exist on the line connecting the outer periphery of the stored wrap roll 5 and the upper end of the inner wall portion 12c.

[0044] In the wrap storage case A of this embodiment, a joining protrusion 12g is provided at a lower position of the inner wall portion 12c of the cut blade receiving portion 12, and the lower end of the wrap holding wall portion 21g of the lid 2 is pressed against and joined to the joining protrusion 12g, thereby maintaining the closed state of the lid 2. However, the joining means is not limited, and the joining protrusion 12g is not necessarily required, and the joining means may be such that engaging portions are provided on the wrap holding wall portion 21g and the cut blade receiving portion 12, respectively, and the two are engaged and joined. It goes without saying that the above embodiments do not limit the invention described in the claims, but are to be treated as examples. [Explanation of symbols]
