Description

  The present invention particularly relates to a film roll storage device in which a film roll formed by winding a wrap film for food packaging, aluminum foil, cooking sheet or the like (hereinafter referred to as “film”) is stored in a film roll storage container. About.

  Usually, a film is wound around a paper tubular body (paper tube) to form a film roll, and the film roll is accommodated in a paper rectangular parallelepiped film roll storage container. This film roll storage container usually has a storage part that opens on the upper surface and stores the film roll, and a lid part that opens and closes the upper surface opening, and a film drawn from the film roll is placed on the tip of the cover part. A cutting blade for cutting is provided. When the film roll is used, the user pulls out the film from the film roll in the film roll storage container and cuts it to a desired length with a cutting blade.

  By the way, for example, when the film is cut or the film roll storage container is moved, the film roll may reversely rotate in the direction opposite to the direction in which the film is drawn out in the film roll storage container. When the film roll rotates in reverse, the film drawn from the film roll may stick to the surface of the rewind film roll. When the films stick to each other, for example, the next time the film is pulled out, it is necessary to search for or remove the leading end of the film, which is inconvenient.

  In order to prevent reverse rotation of the film roll, it has been proposed to attach support members having a ratchet mechanism to both ends of the sheet roll (see Patent Document 1). The ratchet mechanism includes a synthetic resin ratchet hole and a support base.

  The free part 20b has sufficient rigidity and length. For example, the free part 20b has a loop stiffness of 0.2N or more, preferably 0.3N or more. Thereby, when the free part 20b is caught in the inner surface of the film roll storage container 2, it can suppress rotation of the film roll 1 with the rigidity. Moreover, the free part 20b is the length by which the free part 20b is caught on the inner surface of the film roll storage box 2 when the rising angle of the free part 20b from the film roll surface is 90 ° or less in the direction protruding from the surface of the film roll 1. have. The free part 20b preferably has a length such that the free part 20b is caught on the inner surface of the film roll storage box 2 when the rising angle is 60 ° or less, and more preferably the free part when the rising angle is 0 ° to 20 °. 20b is the length that is hooked on the inner surface of the film roll storage box 2, and most preferably is the length that the free portion 20b is hooked on the inner surface of the film roll storage box 2 when the rising angle is 10 °. Thereby, the free part 20b can be reliably brought into contact with the inner surface of the film roll storage box 2 and can restrain the film roll 1 from rotating. The loop stiffness is measured with a loop stiffness tester manufactured by Toyo Seiki Seisakusho under the conditions of 23 ° C. and 50% RH, a loop length of 50 mm, an indentation speed of 5 mm / sec, and an indentation amount of 10 mm.

  As shown in FIGS. 4 and 5, the tubular body 11 includes an annular end surface 30 that is processed so as to be hooked to a convex portion 130 described later on the side wall surface of the film roll storage container 2. For example, the annular end surface 30 is formed with a plurality of recesses 40 provided at equal intervals along the circumferential direction. The recess 40 is formed in, for example, a substantially V shape as shown in FIG. 5, and the side 40a on the V-shaped film drawing direction (B direction in FIG. 5) side rises more than the side 40b on the opposite side. Is formed large. In the present embodiment, a V-shaped recess 40 is formed by making a cut in the annular end surface 30 in the axial direction of the tubular body 11 and bending the portion on the opposite side to the film drawing direction B of the cut. Yes. These recesses 40 are formed in the annular end faces 30 on both sides of the tubular body 11.

  As shown in FIGS. 1 and 2, the film roll storage container 2 has a rectangular parallelepiped shape as a whole, and includes a lid portion 50 and a storage portion 51. The lid 50 includes, for example, a lid cover piece 60, a top plate 61, a side lid cover piece 62, a side plate 63 of the top plate 61, and the like. The storage unit 51 includes a front plate 70, a bottom plate 71, a rear plate 72, a side plate 73 of the front plate 70, a side plate 74 of the bottom plate 71, a side plate 75 of the rear plate 72, a flap 76, and the like. On the surface of the front plate 70, for example, a temporary fixing portion 77 for temporarily fixing an end portion of the film 10 is provided.

  The top plate 61 of the lid 50 extends forward from the upper edge of the rear plate 72 and covers the upper surface opening 51 a of the storage unit 51. The lid cover piece 60 extends from the front edge of the top plate 61 toward the front plate 70 and covers the front surface of the front plate 70. A saw blade 80 for cutting the film 10 drawn from the film roll 1 of the storage unit 51 is provided at the tip of the lid cover piece 60.

  Before the film roll storage device 3 is used, the lid 50 of the film roll storage box 2 is sealed with the opening piece 90. The unsealing piece 90 is located in the lower part of the front surface of the front plate 70 of the storage unit 51, and is formed in a strip shape along the longitudinal direction of the film roll storage container 2. The opening piece 90 is detachably connected to the tip of the lid cover piece 60. Further, the opening piece 90 is bonded to the surface of the front plate 70. When the film roll storage box 2 is opened, the lid 50 can be opened by cutting the opening piece 90 along the longitudinal direction of the box.

  The storage unit 51 is formed in a rectangular parallelepiped shape having an upper surface opening 51a and can store the film roll 1 from the upper surface. The side wall surfaces 100 on both sides in the longitudinal direction of the storage portion 51 are formed by overlapping side plates 75 inside the side plates 74.

  As shown in FIGS. 6 and 7, the side plate 75 of the storage unit 51 is formed with a folded portion 110 that is folded inward and inserted into the tubular body 11 of the film roll 1. The folding part 110 is formed in a downwardly convex tongue shape (substantially circular shape), and a folding line 111 is formed at the upper end. As shown in FIGS. 1 and 2, the side plate 74 stacked on the outside of the side plate 75 is formed with a square pushing piece 120 for pushing the folded portion 110 of the side plate 75 from the outside to fold the folded portion 110 inward. Has been. At the time of manufacturing the storage part 51, the folding part 110 is not folded, and after the film roll 1 is stored in the storage part 51, the pushing piece 120 is pushed from the outside, whereby the folding part 110 is brought inside the tubular body 11. The film roll 1 is held by the folding part 110 and the film roll 1 can be prevented from jumping out of the storage part 51.

  The side wall surface 100 of the storage portion 51 is processed so as to be caught with the annular end surface 30 of the tubular body 11 of the film roll 1. For example, the side wall surface 100 is formed with a convex portion 130 that protrudes toward the annular end surface 30 and hooks into the concave portion 40 of the annular end surface 30. The convex part 130 is provided integrally with the folding part 110, for example, and is formed so as to be folded inside together with the folding part 110. The convex portion 130 is provided, for example, on the front (front plate 70) side of the folding portion 110.

  Examples of the base paper constituting the film roll storage container 2 and the tubular body 11 of the film roll 1 include, but are not limited to, cardboard, coated cardboard, corrugated cardboard, and the like. A kind can be selected and used as appropriate. The base paper may be one obtained by embossing, printing, or laminating using polyethylene or the like on these materials.

  When the user uses the film 10 of the film roll storage device 3 for the first time, the opening piece 90 is cut off to open the lid 50, and the film 10 is pulled out by pulling the small piece 20 of the film roll 1. In the second and subsequent times, the film roll container 2 is held almost horizontally with one hand, the lid 50 is lightly closed, and the film roll 1 in the film roll container 2 is desired with the other hand. Pull out the film 10 of the length. Next, the drawn film 10 is pulled upward, and the film 10 is cut by the cutting blade 80 of the lid 50. The film 10 of the film roll 1 remaining after the cutting is temporarily attached to the temporary fixing portion 77, and the film 10 attached to the temporary fixing portion 77 is pulled out before the next use.

  According to the present embodiment, the concave portion 40 is formed on the annular end surface 30 of the tubular body 11 of the film roll 1, and the convex portion 130 is formed on the side wall surface 100 of the film roll storage container 2. The end surface 30 and the side wall surface 100 of the film roll storage container 2 are respectively hooked so as to be hooked to suppress rotation (reverse rotation) in the direction opposite to the film drawing direction B of the film roll 1. Thereby, it can suppress that the film roll 1 reversely rotates, the film 10 rewinds, and the film 10 adheres to the surface of the film roll 1. Moreover, since only the hooking process is applied to the annular end surface 30 of the annular body 11 of the film roll 1 and the side wall surface 100 of the film roll storage container 2, the cost does not increase, and it can be discarded as it is after use. As a result, it is possible to realize a low-cost and easy-to-use film roll storage device 3 while suppressing reverse rotation of the film roll 1 in the film roll storage container 2.

  Moreover, since the recessed part 40 is formed in the cyclic | annular end surface 30 of the tubular body 11 of the film roll 1, and the convex part 130 hooked with the recessed part 40 is formed in the side wall surface 100 of the film roll storage container 2, the film roll 1 and the film roll A catching mechanism with the storage container 2 can be easily realized.

  Since the concave portions 40 are formed at a plurality of locations along the circumferential direction of the annular end surface 30 of the tubular body 11, the convex portion 130 of the film roll storage container 2 is the concave portion of the film roll 1 regardless of the position of the film roll 1. It becomes easy to catch on 40, and it can suppress reverse rotation of the film roll 1 reliably.

  The recess 40 is formed such that the side 40a on the film drawing direction B side has a larger rising angle than the side 40b on the opposite side, so that the reverse rotation of the film roll 1 can be effectively suppressed. The forward rotation in the film drawing direction side can be appropriately performed. The rising angle referred to here means an angle formed by the side 40a or the side 40b with the annular end surface 30 when the tubular body 11 is viewed from the side as shown in FIG. In the case of FIG. 5, the rising angle of the side 40a is about 90 °, and the rising angle of the side 40b is about 45 °. The rising angle of the side 40a is preferably 60 ° to 120 °, and more preferably 80 ° to 100 °. If it is this range, reverse rotation can be suppressed more effectively. The rising angle of the side 40b is preferably less than 60 °, and more preferably less than 45 °. Within this range, forward rotation can be performed more appropriately. In order to smoothly perform the normal rotation, it is preferable that the portion in contact with the convex portion 130 of the side 40b is R (curved). As shown in FIG. 4, a method of rounding the corner includes a method in which the annular end surface 30 of the tubular body 11 is bent inward, and the bent line portion is used as a side 40 b. The hooking length of the convex portion 130 to the concave portion 40 may be 0.1 mm or more, more preferably 0.5 mm or more, and further preferably 1.0 mm or more. If comprised in this way, the convex part 130 will be easily caught in the recessed part 40. FIG.

  Since the convex portion 130 is formed so that a part of the side wall surface 100 of the film roll storage container 2 protrudes toward the annular end surface 30 side of the film roll 1, for example, the convex portion 130 can be easily formed by merely cutting the side wall surface 100. Can be formed.

  Moreover, since the convex part 130 is provided in the folding part 110, it is not necessary to form two parts which protrude inside from the side wall surface 100, and the structure of the film roll storage container 2 can be simplified.

  Moreover, the small piece 20 is attached to the surface of the film roll 1, and the small piece 20 has the fixing | fixed part 20a fixed to the surface of the film roll 1, and the free | release part 20b released | separated from the film roll surface, The loop stiffness is set to 0.2 N or more. As a result, when the film roll 1 is about to rotate in the film drawing direction B as shown in FIG. 3 before the film roll storage container 2 is opened, the small piece 20 is, for example, the front plate 70 of the film roll storage container 2. It can prevent that the film roll 1 hits an upper end part and rotates to the film extraction direction B side. On the other hand, when the film roll 1 is likely to rotate in the direction opposite to the film drawing direction before the film roll storage container 2 is opened, the above-described convex portion 130 is caught by the concave portion 40 and rotation can be prevented. . As a result, it is possible to prevent the film roll 1 from rotating before opening and the film tip from entering the bottom side of the film roll storage container 2, for example, and to easily find the film tip at the time of opening.

  In the above embodiment, the convex portion 130 is provided integrally with the folding portion 110, but may be provided separately from the folding portion 110. For example, as shown in FIG. 8, a plurality of convex portions 130 may be provided on the front plate 70 side of the folding portion 110 in the side wall surface 100 of the film roll storage container 2 so as to be lined up and down. In such a case, each convex part 130 may have a square plate shape and be bent inward with the upper side being a fold line. Moreover, this convex part 130 may be provided in both sides (the part which opposes via the axial center of the annular end surface 30 of the tubular body 11) across the folding part 110, as shown in FIG. In such a case, the plurality of convex portions 130 on the rear plate 72 side of the folded portion 110 may be arranged in a vertical direction, have a rectangular plate shape, and may be bent inward with the lower side being a fold line.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the idea described in the claims, and these naturally belong to the technical scope of the present invention. It is understood.

  For example, in the above embodiment, the V-shaped recess 40 of the annular end surface 30 of the film roll 1 is formed by bending one side portion of the cut, but the annular end surface 30 is formed in a V-shape as shown in FIG. It may be cut.

  Moreover, the recessed part 40 does not need to be V-shaped, and may have another shape. Moreover, as long as the convex part 130 of the side wall surface 100 of the film roll storage container 2 is caught in the concave part 40, it may have another shape.

  Further, as long as the film roll storage container 2 and the film roll 1 are caught by each other, the film roll storage container 2 side may have a concave portion and the film roll 1 side may have a convex portion. Furthermore, structures other than a convex part and a recessed part may be sufficient.

  The shape and structure of the film roll storage container 2 in the above embodiment are not limited to this. Moreover, the kind of the film 10 wound around the film roll 1 is not limited to the PVDC type, and may be, for example, a PO type or a PVC type.

  The present invention is useful when providing a low-cost and easy-to-use film roll storage device while suppressing reverse rotation of the film roll in the film roll storage container.
