In the roll body holding mechanisms of Patent Documents 1 to 4, the roll body is not sufficiently held in the storage box. That is, when the sheet-like material is pulled out, the roll body rotates and contacts the inner surface of the storage box, so that the roll body moves back and forth and up and down in the storage box and is unstable. For this reason, the following problems have arisen.
(1) The sheet-like material cannot be peeled off smoothly from the roll body, and as a result, the sheet-like material cannot be pulled out smoothly from the storage box.
(2) Reverse rotation of the roll body occurs, and therefore the sheet-like material cut-out opening is rewound into the storage box, making it difficult to pull out the sheet-like material.
(3) The roll body rotates carelessly and the sheet-like material is pulled out excessively.

  An object of this invention is to provide the roll body holding | maintenance mechanism and roll body storage box which can eliminate the above problems.

  The roll body holding mechanism of the present invention is a roll body holding mechanism for holding a roll body in which a sheet-like material is wound around a cylindrical body in a rectangular parallelepiped storage box having an opening / closing lid.

A blade (not shown) for tearing the sheet-like object 31 is provided on the lower edge 1241 of the front surface portion 124 of the lid body 12.

  FIG. 3 is a perspective view of the roll body 3 taken out from the storage box 1. A roll body holding mechanism is attached to the roll body 3. That is, as shown in FIG. 3, a pair of holders 4 are attached to both ends of the roll body 3. Here, this pair of holders 4 constitutes a roll body holding mechanism. FIG. 4 is a perspective view of the roll body 3 with the holder 4 removed. 5 is a cross-sectional view taken along the line VV of FIG. 1, and FIG. 6 is a view taken along the arrow VI of FIG.

  The roll body 3 includes a cylindrical body 32 and a sheet-like object 31 wound around the cylindrical body 32. The cylindrical body 32 is generally made of paper. The sheet-like object 31 is, for example, a food wrap film.

  The holder 4 includes a horizontal member 41 inserted into the cylindrical body 32 and a vertical member 42 provided perpendicular to the horizontal member 41 at the end of the horizontal member 41 on the non-insertion side. . The horizontal member 41 is provided in the center of the vertical member 42 in a side view (viewed with an arrow A). The horizontal member 41 has a form that is inserted into the cylindrical body 32 so as to be in sliding contact. Specifically, the lateral member 41 is a paper-made cylindrical member, and the outer peripheral surface 411 is in sliding contact with the inner surface 321 of the cylindrical body 32. The vertical member 42 has a form that fits into the vertical cross-sectional space of the storage box 1. Specifically, the vertical member 42 is a transparent flat plate member made of plastic, and has a rectangular shape in a side view (in the direction of arrow A) that fits in the vertical cross-sectional space 10 of the storage box 1 as shown in FIG. Has a form. The lateral member 41 may be a columnar shape instead of a cylindrical shape. Further, the vertical member 42 may not have a flat plate shape but may have a flange shape protruding from the horizontal member 41.

  As shown in FIGS. 5 and 6, the holder 4 is attached to the end portion of the roll body 3 by inserting the transverse member 41 into the end portion of the cylindrical body 32 of the roll body 3. At this time, the vertical member 42 is vertical at the edge of the cylindrical body 32. And as FIG. 2 shows, the roll body 3 is accommodated in the storage box 1 in the state in which the holder 4 was attached to both ends.

  In FIG. 5, the storage box 1 is indicated by a one-dot chain line. As can be seen from FIG. 5, the roll body 3 housed in the storage box 1 is floated by the two holders 4 at the center in the vertical direction in the storage box 1, that is, the top and bottom of the storage box 1. The inner surface (that is, the inner surface of the bottom surface portion 111 and the upper surface portion 121) is held without being in contact with it. Further, as can be seen from FIG. 6, the roll body 3 stored in the storage box 1 is floated to the center in the front-rear direction in the storage box 1 by both holders 4, that is, the storage box 1. The front and rear inner surfaces (that is, the inner surfaces of the front surface portion 114 and the rear surface portion 115) are held without being in contact with each other. Therefore, the roll body 3 stored in the storage box 1 with the holders 4 attached to both ends is held in a state of floating in the storage box 1 by the both holders 4.

  In the storage box 1 configured as described above, the sheet-like material 31 is pulled out of the storage box 1 by a required length as shown in FIG. 1 and cut by the blade on the lower edge 1241 of the front surface portion 124 of the lid 12. And use.

  By the way, in the storage box 1 having the above-described configuration, when the sheet-like material 31 is pulled out, the roll body 3 rotates in the arrow R direction (FIG. 2) around the lateral member 41 of both holders 4 in the storage box 1. . That is, the roll body 3 rotates without contacting the upper and lower inner surfaces and the front and rear inner surfaces of the storage box 1 at the center of the longitudinal section in the storage box 1. Therefore, the roll body 3 rotates in a stable state without moving up and down and back and forth. Therefore, in the storage box 1 having the above-described configuration, the sheet-like material 3 can be smoothly pulled out from the roll body 3 and smoothly drawn out from the storage box 1.

  And in the storage box 1 of the said structure, as FIG. 3 shows, the longitudinal direction length L2 inside the box main body 11 of the storage box 1 is the roll body 3 to which the holder 4 was attached to both ends. It is set to be the same as the length L1 in the longitudinal direction. Therefore, the roll body 3 to which the holders 4 are attached at both ends is fitted into the storage box 1 in the longitudinal direction. Therefore, the roll body 3 cannot move in the longitudinal direction in the storage box 1 and thus rotates in a stable state without moving left and right. Therefore, also from this point, in the storage box 1 having the above-described configuration, the sheet-like material 3 can be smoothly peeled off from the roll body 3 and smoothly drawn out from the storage box 1.

  Moreover, as for the roll body holding | maintenance mechanism mentioned above, it is preferable that the outer peripheral surface 411 of the horizontal member 41 of the holder 4 has the tooth | gear 412 as FIG. A plurality of teeth 412 are formed side by side in the circumferential direction (eight in FIG. 8), and the cylindrical body 32 is allowed to rotate in the R direction, but the cylindrical body 32 is rotated in the anti-R direction. It is formed in a form that prevents it. Specifically, the teeth 412 are formed in a sawtooth shape protruding in the R direction. According to this configuration, the roll body 3 can be prevented from rotating reversely (rotating in the anti-R direction) when the sheet-like object 31 is pulled out, so that the sheet-like object 31 can be unwound into the storage box 1. Therefore, it is possible to prevent the sheet-like object 31 from being difficult to be pulled out.

  Further, the roll body holding mechanism described above is shown in FIG. 9 which is a plan view and FIG. 10 which is a cross-sectional view taken along the line XX of FIG. 9, and the cylindrical member 32 of the roll body 3 as shown in FIG. It is preferable that an elastic member 43 that urges the two to be separated from each other is provided. As the elastic member 43, for example, a ring-shaped leaf spring can be used. In this configuration, the elastic member 43 functions to apply a braking force to the rotation of the roll body 3 relative to the holder 4 because it pushes the roll body 3 away from the holder 4. Therefore, according to this configuration, it is possible to reliably prevent the roll body 3 from rotating too much in the R direction when the sheet-like object 31 is pulled out. Can be prevented from being pulled out excessively.

  Note that the roll body holding mechanism of the present invention may be configured by connecting a pair of holders 4 by a bottom plate member 44 at the lower end as shown in FIG. The bottom plate member 44 extends in the longitudinal direction, and has the same length L3 as the longitudinal length L2 (FIG. 3) inside the box body 11 of the storage box 1. When the roll body 3 to which the roll body holding mechanism is attached is stored in the storage box 1, the bottom plate member 44 is installed on the bottom surface portion 111 of the box main body 11 of the storage box 1 and in the box main body 11. Mates in the longitudinal direction. Therefore, the pair of holders 4 are supported by the bottom plate member 44 so as not to move in the longitudinal direction in the storage box 1. Therefore, according to this configuration, the roll body 3 can be held immovably in the longitudinal direction in the storage box 1. For this reason, the roll body 3 rotates in a stable state without moving from side to side. Therefore, also with this configuration, the sheet-like material 31 can be smoothly pulled off from the roll body 3 and smoothly pulled out from the storage box 1.

  Moreover, in the roll body storage box 1 of the present invention, it is preferable that the upper edge portion of the front surface portion 114 of the box body 11 is cut by a predetermined height dimension H as shown in FIG. In this configuration, when the sheet-like material 31 is pulled out of the storage box 1, it can be pulled out through the cut portion 1140 of the front surface portion 114. Therefore, the sheet-like object 31 can be pulled out substantially in the lateral direction, that is, without being brought into contact with the upper edge 1141 (FIG. 2) of the front surface portion 114, it can be pulled out smoothly. Therefore, according to this configuration, the sheet-like object 31 can be smoothly pulled out of the storage box 1. Note that the upper edge portion of the front portion 114 having the cut portion 1140 is preferably reinforced with a hard material 1142 such as belt-like paper.

  Since the present invention can smoothly draw out a sheet-like material from the roll body in the storage box, the industrial utility value is great.
