Utility Model Registration No. 3118518 (page 2-3, FIG. 3) JP 2002-17609 A (page 2-3, FIGS. 1 and 2)

  Since the roll paper storage device according to Patent Document 1 does not have a shaft tube and stores and uses the roll paper as it is, the roll paper rubs against the inner bottom surface and has a large friction. For this reason, in a new state, the roll paper is heavy and difficult to rotate, and when the roll paper is pulled out from the slit, the roll paper may be cut off halfway and unusable. For this reason, the roll paper must be pulled out slowly and carefully so as not to be cut, and there is a problem that it is extremely inconvenient.

  On the other hand, the roll paper storage device according to Patent Document 2 is configured so that the roll paper can freely rotate by inserting the shaft cylinder protruding into the roll paper storage device into the roll paper core. Roll paper from the slit is easy to pull out. However, since this type of roll paper storage device is manufactured to have a strong structure using materials such as synthetic resin, metal, ceramic, and wood, there is a problem that the manufacturing cost is high.

  In order to reduce the production cost as much as possible, it is only necessary to produce a roll paper container using paperboard such as corrugated paper or pressure paper. However, if the shaft cylinder is formed into a cylindrical shape with paperboard, it is necessary to replace the roll paper. For this reason, it is difficult to attach and detach the shaft cylinder. Further, it is still expensive to form the shaft cylinder into a cylindrical shape with paperboard. Similarly, if the shaft cylinder is molded from a synthetic resin material, the molding is simple and the roll paper can be easily replaced as in Patent Document 2, but a roll or a roll is necessary for the molding. There is a problem that the manufacturing cost of the paper storage device increases.

  Accordingly, the present invention has been made to solve the above-described problems, and an object thereof is to provide a roll paper storage device having a shaft cylinder that can be manufactured and made as low as possible and can be attached easily and firmly. It is what.

  In order to achieve this object, a roll paper storage device according to the present invention comprises a pair of support plate parts that are formed of paperboard such as corrugated cardboard or cardboard and arranged in parallel, and the roll paper is provided between the two support plate parts. The shaft tube is formed in a regular polygonal cylinder shape, and is connected to at least one of both end portions along the longitudinal direction and the support plate portion facing the shaft tube. It is characterized in that engagement means that can be removably engaged is provided.

  Specifically, the engaging means includes a tongue piece extending from an end portion of the shaft cylinder and having a through hole, a slit provided in the support plate portion and through which the tongue piece is inserted, and the slit inserted into the slit. And a stopper that fits into both the through holes when the tongue piece is bent.

  The roll paper storage device according to claim 1 or 2 is formed such that a shaft cylinder disposed between both support plate portions is formed into a regular polygonal cylinder shape, and faces at least one of both end portions along the longitudinal direction. Since the engaging means that can be detachably engaged with the support plate portion is provided, the shaft tube can also be formed of paperboard, and a strong configuration can be obtained. In addition, since the shaft tube is formed into a regular polygonal shape and can be formed simply by forming a broken line and bending it, it can be easily manufactured and attached as compared with a cylindrical one, and the forming cost is low. Thereby, there is an effect that the roll paper storage tool is formed into a strong structure by the paperboard, and the production cost can be extremely low.

  Hereinafter, embodiments of a roll paper storage device according to the present invention will be described in detail with reference to the drawings. 1 to 6 show a roll paper storage device according to the first embodiment, and FIGS. 7 to 12 show a roll paper storage device according to the second embodiment.

  The roll paper storage device A1 is formed of double-sided cardboard paper d as a paperboard, and includes a storage device body 1 and a shaft cylinder 2 formed separately from the storage device body 1. The storage device main body 1 includes a substantially square bottom plate portion 10 and support plate portions 11 and 11 which are integrally provided on opposite side edges of the bottom plate portion 10 and are arranged upright and parallel to each other. Both support plate parts 11 and 11 are trapezoidal. Both the bottom plate portion 10 and both support plate portions 11 and 11 are punched into a predetermined shape, and are folded by providing a folding line at a predetermined location, whereby the corrugated cardboard paper d is laminated twice to obtain a required strength. It is like that.

  Along the both side edges between the support plate portions 11, 11 in the bottom plate portion 10, the upper corrugated cardboard paper d is folded upward across the support plate portions 11, 11 to form ridge portions 12, 12 having a triangular cross section. Is provided. The inclination angle of the outer surface 12a of the protrusions 12 and 12 with respect to the bottom plate part 10 is set to be the same as the inclination angle of the side edges 11a with respect to the bottom plate part 10 in the standing support plate parts 11 and 11, , 12 substantially coincide with both side edges 11a, 11a of both support plate portions 11, 11 so as to improve the design. Moreover, the outer side surface 12a of both the protrusion parts 12 and 12 is provided in the side edges 10a and 10a which oppose both the support board parts 11 and 11 in the corrugated paper d of the upper side of the baseplate part 10 including both protrusion parts 12 and 12.

And the slit 15 as an engaging means is opened in the outer corrugated paper d along the lower side edge in each hollow part 14. In addition, a through hole 16 as a circular engagement means is formed in the outer corrugated cardboard d at the substantially central portion in each recess 14.

  The shaft tube 2 is made of rectangular corrugated cardboard d, and is formed into a regular triangular tube shape by being bent in the same direction by three parallel folding lines 20 along the longitudinal direction. The bending pieces 21a and 21b located at both ends in the short direction are provided with an insertion piece 22 and an insertion recess 23 into which the insertion piece 22 is inserted at a corresponding position of the outer edge. In addition, tongue pieces 24 and 24 serving as semicircular engaging means inserted into the slits 15 of the recessed portion 14 are provided at both ends in the longitudinal direction of the bent piece 21c sandwiched between the bent lines 20 via the bent lines 25 and 25. Through holes 26 and 26 are formed as engaging means that match the through holes 16 and 16 on the support plate portions 11 and 11 side when the tongue pieces 24 and 24 are inserted into the slit 15 and bent. ing.

  The roll paper container A1 according to the first embodiment has the above-described configuration, and the assembly method will be described next. First, the bent pieces 21a, 21b, and 21c are bent in the same direction by the fold line 20, respectively, and the bent piece 21a provided with the insertion piece 22 is overlapped with the bent piece 21b provided with the insertion recess 23 inside. The insertion piece 22 is inserted into the insertion recess 23. As a result, a regular triangular cylindrical shaft 2 is formed. Then, the shaft cylinder 2 is inserted through the core S of the roll paper R.

  Therefore, the tongue piece 24 at one end in the longitudinal direction of the shaft tube 2 is inserted into the slit 15 of the recessed portion 14 in a state where the one support plate portion 11 of the container main body 1 is raised and is fitted in the notch recess 13 of the bottom plate portion 10. Insert through. Further, the tongue piece 24 is bent toward the through hole 16. At this time, both the through holes 16 and 26 match. And the stopper 3 as an engaging means is inserted in both the through-holes 16 and 26, and it latches. As a result, the corrugated cardboard d and the tongue piece 24 on the outside of the support plate portion 11 are brought into contact with the recess 14 on the support plate portion 11 side as shown in FIGS. It is clamped together and held firmly. This operation is similarly performed for the support plate 11 on the other side of the storage device main body 1.

  The stopper 3 is formed from a synthetic resin material, and has a disk-shaped head 30 having an outer diameter larger than the inner diameter of the through holes 16 and 26 as shown in FIGS. On one side surface of the head portion 30, halved shaft portions 31 a and 31 b that protrude perpendicularly to the one side surface and separate along the center axis line are projected. One shaft portion 31a is provided with a locking projection 32 orthogonal to the shaft portion 31a, and the other shaft portion 31b is provided with a vertically long locking projection 33 orthogonal to the shaft portion 31b.
