Description

[Technical field]

[0001] The present invention relates to a case for a wrap film storage box (wrap case) that houses and protects a wrap film storage box that contains wrap film for food packaging. Note that the term "wrap film" in this specification includes resin films such as polyvinylidene chloride (PVDC), polyethylene (PE), and polyvinyl chloride (PVC), as well as Press'n Seal (registered trademark), aluminum foil, and cooking sheet. [Background technology]

[0002] A wrap film storage box that stores wrap film for packaging food is made of paper and is not durable, so as shown in Figure 15(a), when the front part 103 having the cutting edge 102 of the lid 101b of the wrap film storage box 101 is pressed, the front part 103 of the lid 101b and the front plate 104 of the main body 101a are depressed, making it difficult to cut the wrap film 105. As the wrap film 105 is repeatedly used, the wrap film storage box 101 gradually becomes soft and easily deformed, making it increasingly difficult to cut the wrap film 105.

[0003] Furthermore, as shown in FIG. 15(b), a flap 106 hanging downward from the upper end is provided on the front panel 104 of the wrap film storage box 101, and the cut end of the wrap film 105 can be pulled away from the front panel 104 to make it easy to remove the wrap film 105. However, there was a problem in that the flap 106 did not lift up sufficiently from the front panel 104, making it difficult to pick up the wrap film 105.

[0004] Patent Document 1 describes a wrap film storage box with cover pieces attached to the top and front lids of the wrap film storage box. Patent Document 2 describes a lid cover that covers the top, front, and both side surfaces of the lid of the wrap film storage box. Patent Document 3 describes a protector that is attached to the front and top of the lid of the wrap film storage box using an adhesive sheet.

[0005] However, since the device described in References 1-3 is attached to the lid of a wrap film storage box, it can prevent deformation of the lid of the wrap film storage box when the wrap film is cut, but it is not effective in preventing deformation of the main body, particularly the front panel, and there is a problem that the lid becomes large, making it difficult to open and close the lid.

[0006] The present inventor has invented a packaging box storage case for storing packaging boxes containing wrap film rolls such as wrap film and aluminum foil, as shown in Patent Document 4. This packaging box storage case is a rectangular container consisting of a front wall, a rear wall, left and right side walls, and a bottom wall, with the front wall lower than the rear wall and the left and right side walls, and stores the wrap film storage box from the upper opening with the cutting blade facing the front wall, holds the case with the wrap film storage box stored, places a thumb on the lid exposed from the case to open it and take out the wrap film, closes the lid, and cuts the wrap film with the cutting blade of the lid. This case protects and reinforces the main body of the wrap film storage box, so it can be stored upright, and exhibits excellent functions such as improved durability, ease of holding, and ease of cutting the wrap film.

[0023] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0024] First Embodiment 1 shows a case for a wrap film storage box (hereinafter referred to as a "wrap case") 1 for storing a wrap film storage box 11 according to a first embodiment of the present invention. The wrap case 1 is for storing the wrap film storage box 11 which stores a wrap film roll 21 made of a resin film such as polyvinylidene chloride (PVDC), polyethylene (PE), polyvinyl chloride (PVC), or the like.

[0025] Before describing the wrap case 1, an existing wrap film storage box 11 will be briefly described. The wrap film storage box 11 has a main body 11a consisting of a front panel 12, a rear panel 13, left and right side panels 14a, 14b, and a bottom panel 15, and a lid 11b consisting of a top surface portion 16 connected to the upper end of the rear panel 13, a front surface portion 17 provided at the front end of the top surface portion 16, and side surfaces 18a, 18b provided at both left and right ends of the top surface portion 16. A wrap film roll 21 is stored in the main body 11a. A flap 19 is provided on the front panel 12 of the main body 11a, hanging diagonally forward from the upper end. A cutting blade 20 for cutting the wrap film 21a is provided at the lower end of the front surface portion 17 of the lid 11b. The tip of the wrap film 21a is pulled out a predetermined length from the upper end of the front panel 12 over the flap 19, the lid body 11b is closed, and the wrap film 21a is cut off by the cutting blade 20 on the front portion 17 of the lid body 11b.

[0026] The wrap case 1 is a rectangular container having a front wall 2, a rear wall 3, left and right side walls 4a, 4b, and a bottom wall 5, with an opening on the side facing the bottom wall 5 (the upper side). The wrap case is made of plastic, but may also be made of metal such as aluminum, or of cardboard or corrugated cardboard. The inner length and width dimensions of the wrap case 1 are large enough to accommodate a wrap film storage box 11.

[0027] The height of the front wall 2 is lower than the heights of the rear wall 3 and the left and right side walls 4a, 4b, and higher than the position of the cutting edge 20 of the wrap film storage box 11. When the wrap film storage box 11 is stored in the wrap case 1, the upper end of the front wall 2 is inserted between the front plate 12 and the flap 19 of the main body 11a of the wrap film storage box 11. This allows the flap 19 to be sufficiently separated from the front plate 12. Slits 6a, 6b are formed at both ends of the front wall 2 from the opening end toward the bottom wall 5. The width of the slits 6a, 6b is large enough to allow the side portions 18a, 18b of the lid body 11b to enter and exit when the lid body 11b of the wrap film storage box 11 is opened and closed. The lower ends of the slits 6a, 6b are located lower than the lower ends of the side portions 18a, 18b of the lid body 11b when the wrap film storage box 11 is closed, as shown in FIG. 10. As a result, when the lid body 11b of the wrap film storage box 11 is opened or closed, the side portions 18a, 18b of the lid body 11b do not interfere with the front wall portion 2 of the wrap case 1.

[0028] The rear wall 3 has the same height as the wrap film storage box 11, and when the wrap film storage box 11 is stored in the wrap case 1, the rear panel 13 of the wrap film storage box 11 is covered with the rear wall 3 of the wrap case 1.

[0029] The left and right side walls 4a, 4b have the same height as the rear wall 3, i.e., the height of the wrap film storage box 11, and when the wrap film storage box 11 is stored in the wrap case 1, the left and right side plates 14a, 14b and side surfaces 18a, 18b of the wrap film storage box 11 are covered by the left and right side walls 4a, 4b of the wrap case 1. The inner surfaces of the left and right side walls 4a, 4b are formed with protrusions 7a, 7b that protrude toward the inside of the wrap case 1. The upper ends of the protrusions 7a, 7b form tapered surfaces 4c, 4d that incline toward the inner surfaces of the side walls 4a, 4b, as shown in Fig. 8. The distance between the left and right protrusions 7a, 7b is formed slightly smaller than the distance between the outer surfaces of the left and right side plates 14a, 14b of the main body 11a of the wrap film storage box 11, and the wrap film storage box 11 is pressed into between the protrusions 7a, 7b of the left and right side wall portions 4a, 4b of the wrap case 1 so that it does not easily come out.

[0030] 7 and 8, the bottom wall 5 is raised higher than the lower ends of the front wall 2, rear wall 3, and left and right side walls 4a, 4b. This forms a handle 8 that allows the tips of the little finger, ring finger, and middle finger to be hooked when the wrap case 1 containing the wrap film storage box 11 is held in one hand.

[0031] Next, the operation of the plastic wrap case 1 of the first embodiment will be described.

[0032] First, the wrap film storage box 11 containing the wrap film roll 21 is housed in the wrap case 1. The wrap film storage box 11 is housed in the wrap case 1 with the lid 11b open. The front wall 2 of the wrap case 1 is inserted between the flap 19 of the wrap film storage box 11 and the front plate 12, so that the flap 19 moves away from the front plate 12. When the wrap film storage box 11 is pushed between the protrusions 7a, 7b of the left and right side wall portions 4a, 4b of the wrap case 1, the protrusions 7a, 7b of the wrap case 1 are pressed into the wrap film storage box 11 while pressing against the left and right side plates 14a, 14b. This allows the wrap film storage box 11 to be housed in the wrap case 1 without rattling. When the lid body 11b of the wrap film storage box 11 is closed, the left and right side portions 18a, 18b of the lid body 11b enter the left and right slits 6a, 6b of the front wall portion 2 of the wrap case 1, so that the lid body 11b can be completely closed without interfering with the front wall portion 2.

[0033] The wrap case 1 containing the wrap film storage box 11 can be placed horizontally with the bottom wall part 5 facing down, and can also be placed vertically with either the left or right side part 4a, 4b facing down, thereby saving storage space.

[0034] To use the wrap film 21a of the wrap film storage box 11 housed in the wrap case 1, hold the wrap case 1 with the wrap film storage box 11 housed in it in one hand, as shown in Fig. 9. It is preferable to hook the tips of the little finger, ring finger, and middle finger on the handles 8 on the bottom plate and hook the thumb on the front surface 17 of the lid 11b. Open the lid 11b of the wrap film storage box 11 with your thumb, pinch the tip of the wrap film 21a of the wrap film roll 21 with the other hand, and pull it out a predetermined length from the top end of the front plate 12 over the flap 19 to the outside, and then close the lid 11b.

[0035] With the lid 11b closed, the wrap film 21a is cut off with the cutting blade 20 while pressing the front portion 17 of the lid 11b. When the front portion 17 of the lid 11b is pressed, the pressing force is received by the front wall portion 2 of the wrap case 1, and is not transmitted to the front plate 12 of the main body 11a of the wrap case storage box 11. This prevents the front plate 12 of the main body 11a of the wrap film storage box 11 and the front portion 17 of the lid 11b from being deformed, and the wrap film 21a can be securely pressed and easily cut. This is because, even if the wrap film 21a is consumed and the roll diameter becomes smaller, and the gap between the wrap film roll 21 and the front plate 12 becomes larger, when the front portion 17 of the lid 11b is pressed to cut the wrap film 21a, the main body 11a and the lid 11b of the wrap film storage box 11 are not dented, so that the wrap film 21a can be securely cut off to the end, even if there is only a little wrap film 21a remaining.

[0036] When the lid 11b of the wrap film storage box 11 is closed from the state shown in Fig. 11, the flap 19 is pushed by the front surface 17 of the lid 11b against the elasticity of the flap 19 which tends to move away from the front wall 2 of the wrap case 1, as shown in Fig. 10. As a result, the wrap film 21a overlapping the flap 19 of the body 11a of the wrap film storage box 11 is pushed by the front surface 17 of the lid 11b together with the flap 19 and approaches the front wall 2 of the wrap case 1. If the lid 11b of the wrap film storage box 11 is opened in order to continue using the wrap film 21a, as shown in Fig. 11, the flap 19 of the wrap film storage box 11 moves away from the front panel 12 and the front wall 2 due to its elasticity, so that the end of the wrap film 21a can be easily picked up. Furthermore, if the wrap film 21a is provided with an adhesive portion 19a (see FIG. 1) coated with an adhesive to prevent rewinding, the wrap film 21a adheres to the adhesive portion 19a when pressed against the front portion 17 of the lid body 11b, thereby reliably preventing the wrap film 21a from rewinding.

[0037] <Second embodiment> 12 shows a wrap case 1' according to a second embodiment of the present invention. This wrap case 1' is suitable for storing a wrap film storage box 11' that stores a wrap film roll 21 of Press'n Seal (registered trademark), aluminum foil, or cooking sheet.

[0038] This type of wrap film storage box 11' differs from the wrap film storage box 11 described above, which stores a wrap film roll 21 made of a resin film such as polyvinylidene chloride (PVDC), in that it does not have a flap and is made of soft paper. As a result, as the roll diameter becomes smaller, the main body 11a and lid 11b deform, making it difficult to cut the film 21a, which is a problem.

[0039] The wrap case 1' of the second embodiment is similar to the wrap case 1 of the first embodiment except that the height of the front wall portion 2 is the same as the height of the rear wall portion 3 and the left and right wall portions 4a, 4b, and corresponding parts are given the same symbols and their descriptions are omitted.

[0040] The function of the wrap case 1' of the second embodiment is basically the same as that of the wrap case 1 of the first embodiment, so a detailed explanation will be omitted, but since the height of the front wall portion 2 is the same as the height of the rear wall portion 3 and the left and right wall portions 4a, 4b, the front wall portion 2 covers the entire front panel 12 of the main body 11a of the wrap case storage box 11', and its rigidity is greater than that of the front wall portion 2 of the wrap case 1 of the first embodiment.

[0041] Therefore, when the lid 11b is closed and the wrap film 21a is cut off with the cutting blade 20 while pressing the front portion 17 of the lid 11b, the pressing force acting on the front portion 17 of the lid 11b is received by the front wall portion 2 of the wrap case 1' and is not transmitted to the front plate 12 of the main body 11a of the wrap case storage box 11'. Therefore, even if the wrap film storage box 11' is made of soft paper, deformation of the main body 11a and the lid 11b is prevented, and the wrap film 21a of Press'n Seal (registered trademark), aluminum foil, or cooking sheet can be securely pressed down and easily cut. This is because even if the wrap film 21a is consumed and the roll diameter becomes smaller, causing the gap between the wrap film roll 21 and the front panel 12 to become larger, when the front portion 17 of the lid body 11b is pressed to cut the wrap film 21a, the main body a and the lid body 11b of the wrap film storage box 11' will not be dented, so that even if there is only a little wrap film 21a left, the wrap film 21a can be reliably cut off to the very end.

[0042] <Third embodiment> FIG. 13 shows a combination of a wrap case 1 and a core holder 31 according to the third embodiment of the present invention.

[0043] The wrap case 1 is similar to the wrap case 1 of the first embodiment, so the corresponding parts are given the same reference numerals and the description thereof is omitted. The wrap case 1 may be the wrap case 1' of the second embodiment.

[0044] The core receiver 31 is used to support the wrap film roll 21 stored in the wrap film storage box 11 when the wrap case 1 is in use. The core receiver 31 is composed of a shaft portion 32 and a support piece 33, as shown in FIG.

[0045] The shaft portion 32 is cylindrical or tubular and is inserted into the hollow core of the wrap film roll 21 from both sides.

[0046] The support piece 33 is made of paper or plastic, has a square shape approximately the same as the left and right side plates 14a, 14b, or a circular plate shape that contacts three sides of the left and right side plates 14a, 14b, and is adhered or integrally attached to one end of the shaft portion 32 so as to abut against the inner surfaces of the left and right side plates 14a, 14b of the main body 11a of the wrap film storage box 11. The support piece 33 supports both ends of the wrap film roll 21 in a state where it is floating within the main body 11a of the wrap film storage box 11, and is designed so that the center position does not change even when the wrap film 21a is consumed.

[0047] The method of using the combination of the wrap case 1 and core receiver 31 according to the third embodiment will be described below. First, the wrap film roll 21 is removed from the wrap film storage box 11, and the shaft parts 32 of the core receiver 31 are inserted into both ends of the hollow core, and then the wrap film roll 21 is returned to the wrap film storage box 11. This allows the wrap film roll 21 to rotate around the shaft parts 32 of the core receiver 31, making it possible to smoothly pull out the wrap film 21a. Furthermore, even if there is only a little wrap film 21a left, both ends are supported at the same position and are not eccentric, so there is no rattling noise or rewinding of the wrap film roll 21.

[0048] The action of the wrap case 1 itself is as described in the first and second embodiments. Thus, the combination of the wrap scale 1 and core receiver 21 in the third embodiment not only prevents the wrap film storage box 11 from deforming the main body 11a and lid 11b of the wrap film storage box 11 due to the wrap case 1, making it easier to cut the wrap film 21a, but also has the synergistic effect of allowing the wrap film 21a to be smoothly pulled out and preventing it from rewinding due to the core receiver 31.

[0049] The present invention is not limited to the above-described embodiment, and various changes and modifications can be made within the scope of the gist of the present invention.

[0050] For example, a magnet 34 may be provided on the rear surface of the bottom wall 5 of the wrap case 1, 1' as shown in FIG. 5, so that the wrap case 1, 1' can be stored by being attracted to a wall surface made of a magnetic material such as a refrigerator. In addition, in the above embodiment, the handle portion 8 is provided around the entire periphery of the bottom wall portion 5 of the wrap case 1, 1', but this handle portion 8 may be a recess provided in a part of the bottom wall portion 5.
