Description

  The present invention relates to a roll paper storage container, and in particular, relates to a roll paper storage container rich in design as well as functionality.

  Toilet paper, which is a representative example of roll paper, has been conventionally used mainly during defecation and urination. Toilet paper is cheaper than tissue paper contained in paper boxes, etc., can be used by adjusting the desired amount, and does not require a package such as paper boxes, which also helps reduce waste If it is used other than defecation and urination, it is very preferable from the viewpoint of household budget and environmental conservation.

  However, bare toilet paper that is not stored in a container or the like looks cheap, and the act of using it in a living room or kitchen and placing it on a table or the like after use makes it look bad and ruins the interior space.

  Therefore, it would be highly desirable if there is a roll paper storage container that can be used in place of tissue paper in the kitchen or living room and has both appearance design and functionality.

  A conventional toilet paper storage container reflects its use, a cylindrical body that holds toilet paper, a connection portion that is rotatably connected at both ends of the cylindrical body, and a pressing portion that presses and cuts the toilet paper And the structure provided with the attaching part which can be attached to a toilet room wall surface is common. These storage containers usually have an appearance specialized only in functionality suitable for defecation and urination, and do not have a design that matches the scenery of the living room or kitchen. Further, as described above, these storage containers are generally fixed, and are not substitutes for placement and storage in any place in the room.

  In addition, roll paper storage containers on the premise of uses other than defecation and urination have already been proposed, and are disclosed in, for example, Patent Documents 1 to 9.

  Among these, in the documents of Patent Documents 1 to 4, a substantially cylindrical body having a size capable of accommodating roll paper is formed, and roll paper is provided at the center of the upper lid portion or the lower lid portion of the cylindrical body. A storage container having a structure in which a circular opening that can be taken out is provided is disclosed. However, in order to use these storage containers, the roll paper core (usually a paper core) must be removed in advance before the roll paper is stored. Such additional sampling is a relatively difficult task and is particularly troublesome for powerless women and children. In the worst case, there is also a risk that some of the nails break during the work.

  On the other hand, although the literature of patent documents 5-8 comprises a substantially cylindrical body like the above, on the outer peripheral side surface of this cylindrical body, it is parallel to the axis line of this cylindrical body, and from the width | variety of roll paper. A structure in which a slit (elongated opening) is provided so as to extend long has been proposed. However, since these storage containers are provided with a slit on a side surface of the storage container, when the slit does not face the user, the user grips the storage container and changes its orientation. It is necessary to take out and cut the roll paper while holding the storage container. On the other hand, if the storage container does not have a roll paper rotation mechanism, the roll paper does not come out of the slot smoothly due to friction between the roll paper installation surface in the storage container and the roll paper, and it is difficult to take out. There was also. Even when a rotating mechanism is provided, the outer end of the roll paper enters the storage container through the slot when the user grips the storage container or comes into contact with the storage container. There was also a problem. Further, as described in FIG. 5 of Patent Document 5, there is another problem that sufficient sharpness cannot be guaranteed unless the container is fixed with a hand different from the hand for pulling out the roll paper.

  Furthermore, in the document of Patent Document 9, a substantially cylindrical body having a size capable of accommodating roll paper is formed, and an opening in which the roll paper can be taken out is formed in an upper lid portion or a lower lid portion of the cylindrical body. And a structure provided with a holding member that rotates while holding the roll paper at its central opening, and a circular guide member that connects to the end of the holding member and covers the upper or lower surface of the roll paper. It is disclosed. Since the holding container, the circular guide member, and the roll paper rotate integrally with each other, the roll paper is pulled out in the axial direction of the roll paper while being guided by the smooth outer edge of the circular guide member during use. Become. However, since this container usually also has a rotation mechanism in the container, there is a problem that the roll paper enters the inside of the sudden beat like the above Patent Documents 5 to 8, and the sharpness of the roll paper is guaranteed. Therefore, it has been necessary to fix the storage container or the rotation mechanism inside the container so that it does not move with a hand different from the hand that pulls out the roll paper.

  The present invention has been proposed in view of such a conventional situation, and an object of the present invention is to provide a roll paper storage container that eliminates the disadvantages of the prior art. That is, an object of the present invention is to provide a roll paper storage container rich in design as well as functionality and cost performance.

  Furthermore, an object of the present invention is to provide a roll paper storage container that does not require additional work such as extraction of a core material when the roll paper is used, and can easily take out and cut the roll paper.

  Even if the roll paper itself is difficult to rotate, the inventor can easily and smoothly pull out even if the outer end portion of the roll paper is spiral (in other words, the roll paper is drawn with respect to its central axis). In the cross section of the roll paper orthogonal to each other, it was found that the paper was moved in the direction of one of the central axes while moving in the tangential direction), and the present invention was completed. In addition, the present inventor more preferably, contrary to some of the functions of the prior art, when the roll paper itself is fixed without being rotated, the performance of taking out and cutting the roll paper is further improved. As a result, the present inventors have completed a preferred embodiment of the present invention.

That is, the present invention adopts the following configuration / features.
1. A roll paper storage container comprising a cylindrical main body provided with a circular opening at the top and a bottom surface, and a circular lid for covering the opening,
The cylindrical main body further includes a support portion that stands from the bottom surface along a central axis and supports the circular lid portion,
The circular lid portion has an outer diameter smaller than the inner diameter of the cylindrical main body so that a gap is generated along an outer edge in a state where the cylindrical main body and the circular lid portion are assembled.
A roll paper storage container, wherein a part of the outer edge is notched and a notch surface is provided.
2. 2. A roll paper container according to claim 1, wherein a blade portion is installed or formed on at least a part of the cut surface.
3. The roll paper storage container according to 1 or 2, wherein at least a part of the outer diameter of the support portion is larger than the inner diameter of the core opening of the roll paper.
4). The roll paper storage container according to any one of claims 1 to 3, wherein an elastic body is further provided on at least a part of an outer edge of the support portion.

  The roll paper storage container of the present invention is installed in the circular opening of the cylindrical main body so that a gap is formed along the outer edge of the lid, and the central axis extends from the bottom surface of the cylindrical main body along the central axis. In order to adopt a configuration having a standing support part, the roll paper is housed in the cylindrical body while being inserted into the support member, and the outer end of the roll paper is spirally rotated from the gap at the outer edge of the lid part. It becomes possible to take it out. Therefore, with ordinary roll paper, most methods draw out the outer tip in the direction opposite to the winding direction at the time of manufacture (the tangential direction in the circle of the roll paper cross section). In addition to this tangential direction, it is pulled out in a spiral while moving in an axial direction perpendicular to this tangential direction.

  Since the roll paper storage container of the present invention is provided with a sawtooth-shaped notch in a part of the outer edge of the circular lid, it can be rotated along the outer edge in the plan view with the central axis of the circular lid as a base point. Without disturbing the movement of the roll paper, it is possible to easily cut the roll paper by directing the direction of movement slightly toward the base point.

  Furthermore, according to a preferred aspect of the roll paper storage container of the present invention, since at least a part of the outer diameter of the support portion is larger than the inner diameter of the core opening of the roll paper, the roll paper is fixed to the cylindrical main body. It becomes possible to take out the roll paper while making it happen. Thereby, it becomes easy to cut | disconnect a roll paper in a sawtooth-shaped notch part, and pulling out and cutting | disconnection of roll paper are attained only with one hand which pulls out roll paper. When at least a part of the support part includes an elastic body as in another preferred aspect of the present invention, insertion into the support part is facilitated when the roll paper is accommodated.

1 is a perspective view showing an appearance of a roll paper storage container 1 according to Example 1. FIG. FIG. 2A shows a plan view of the roll paper storage container 1 according to the first embodiment, and FIG. 2B shows a cross-sectional view. It is the figure which showed each step of the usage method of the roll paper storage container 1 of this invention. It is the figure which showed the exploded perspective view of the roll paper storage container which concerns on Example 3. FIG. It is the figure which showed the exploded perspective view of the roll paper storage container which concerns on Example 4. FIG.

Hereinafter, although the present invention will be described based on the embodiments shown in the drawings, the present invention is not limited to the following specific embodiments.

(Structure of roll paper storage container)
FIG. 1 is a perspective view showing an appearance of a roll paper storage container 1 according to Embodiment 1 of the present invention. 2A shows a plan view of the roll paper storage container 1 according to the first embodiment, and FIG. 2B shows the storage container 1 broken along the line AA shown in FIG. A cross-sectional view is shown.

  As shown in FIGS. 1 and 2, the roll paper storage container 1 includes a hollow cylindrical main body 10 having a circular opening 11 provided on the upper side and a bottom surface 12, and a circular lid that covers the opening 11. 20. Here, examples of the preferable hollow cylindrical shape of the main body 10 include a hollow cylindrical shape, a bowl shape, a cubic shape, and the like. Not. The material of the main body 10 and the circular lid portion 20 can be selected from a wide range of materials such as resin, metal, and glass. Resin is preferable from the viewpoints of weight reduction, manufacturing cost, ease of manufacture, and the like. When resin is selected, each element of the storage container 1 can be manufactured in large quantities, at low cost, and with high precision by injection molding.

  In addition, as shown in FIG. 2B, the main body 10 further includes a support portion 13 that stands from the bottom surface 12 along the central axis O and supports the circular lid portion 20. Preferably, the support portion 13 has a hollow cylindrical shape extending from the bottom surface 12 along the central axis O to the vicinity of the circular opening 11 as shown in the drawing, and further, the projected area at the tip position near the circular opening 11. It has a tapered shape so that (the area of the projected circle) is slightly smaller than the projected area at the bottom surface position. Here, the projected circle at the tip of the support portion 13 has an outer diameter that is sufficiently smaller than the inner diameter of the core opening 32 of the roll paper 30.

  By adopting the hollow shape as described above, the cost of the material such as resin is suppressed, and further, by adopting the shape of the desired dimension with the taper, the support portion 13 is inserted into the core opening portion 32 of the roll paper 30. As a result, the roll paper 30 can be easily accommodated in the storage container 1.

  In the circular lid portion 20 of the first embodiment, a solid cylindrical body 24 extends downward from the central point along the central axis O, and this solid cylindrical body 24 is suitable for the hollow internal space of the support portion 13. It has a structure that fits. Thereby, attachment and detachment to the main body of the circular lid part 20 become easy.

  The circular lid 20 has an outer diameter smaller than the inner diameter of the main body 10 so that a gap G is formed along the outer edge 21 in a state where the main body 10 and the circular lid 20 are assembled. Preferably, the outer diameter of the circular lid portion 20 is determined so that a gap G of about 2 mm to 5 mm is generated in the radial direction. As a result, the outer front end 31 of the roll paper 30 at an arbitrary position in the outer peripheral direction is taken out from the inside of the storage container 1 through the gap G, and the gap G defined by the main body 10 and the circular lid portion 20 is removed. A desired length can be pulled out along. In addition, the movement of the outer front end 31 at the time of drawing out is three-dimensional and takes a spiral trajectory that is unwound from the outer periphery of the roll paper 30. Accordingly, smooth movement is guaranteed on the path without any resistance such as obstacles or friction.

  A part of the outer edge 21 is notched, and a blade part 23 is formed on at least a part of the notch surface 22. As this blade part 23, for example, a metal blade part 23 is additionally installed on the notch surface 22, a sawtooth cross-sectional shape is formed on the notch surface 22, or the other outer edge of the circular lid part 20 has a surface roughness. A surface larger than 21 may be provided. Thereby, as shown in FIG. 2A, the outer front end 31 of the roll paper 30 that is movable in the tangential direction of the outer edge 21 of the circular lid portion 20 in the gap G is centered on the central axis O in the notched space. It is possible to cut the roll paper 30 by moving it toward and making it contact the sawtooth shape of the notch surface 22.

(How to use roll paper storage container)
FIG. 3 is a diagram showing each stage of the method of using the storage container 1 of the present invention. First, as shown in FIG. 3A, the circular lid 20 is removed from the main body 1 to expose the circular opening 11. Next, as shown in FIG. 3B, the roll paper 30 is accommodated in the main body 10 while the core opening 32 of the roll paper 30 is inserted into the support portion 13. Then, as shown in FIG. 3 (c), the circular lid portion 20 is attached to the main body 1 again. At that time, the outer front end 31 of the roll paper 30 is pulled out from the circular opening 11 of the main body 1 in advance.

  As shown in FIG. 3 (d), it is actually used, and is pulled out by a necessary length while spirally rotating along the gap G while grasping the outer front end 31 of the roll paper 30. The roll paper 30 is cut | disconnected using the sword part 23 installed in the notch surface 22 of the circular cover part 20 as shown to (e). Although the usage method as described above is performed every time, the roll paper 30 can be used in a necessary amount depending on the situation.

  Next, the roll paper storage container 1 which concerns on another Example (not shown) of this invention is demonstrated. In the roll paper storage container 1 according to the second embodiment, at least a part of the outer diameter of the support portion 13 of the main body 10 is larger than the inner diameter of the core opening 32 of the roll paper 30. Although not shown, for example, the support portion 13 may have a tapered hollow cylindrical shape that expands toward the bottom surface 12, and the outer diameter of the support portion 13 near the bottom surface 12 may be larger than the inner diameter of the core opening portion 32. Conceivable.

  By adopting the second embodiment having such a configuration, the roll paper 30 can be fixed to the main body 10, and the roll paper 30 is attached to the main body 10 even if the storage container 1 is moved, contacted, dropped, or the like. On the other hand, it becomes difficult to move relative to each other, and the problem that the outer end 31 enters the inside of the storage container 1 is unlikely to occur. Further, since the roll paper 30 does not move relative to the main body 10 or the circular lid portion 20, the roll paper 30 can be easily cut at the blade portion 23 of the notch surface 22, and a better sharpness is guaranteed. For example, the roll paper 30 can be pulled out and cut only by using only the hand holding the roll paper 30.

  In addition, the structure of Example 2 other than the characteristic demonstrated above is the same as that of the structure of Example 1, and description about these is abbreviate | omitted. The same applies to Examples 3 and 4 described later.

  Next, the roll paper storage container 1 which concerns on Example 3 of this invention is demonstrated. The roll paper storage container 1 according to the third embodiment is characterized in that an elastic body 41 is further provided on at least a part of the outer edge of the support portion 13. For example, as shown in FIG. 4, a hollow cylindrical elastic body 41 may be attached to a part of the outer edge of the support portion 13. As the material of the elastic body 41, a rubber material or a silicon material is preferable.

  By adopting the third embodiment having such a configuration, the roll paper 30 can be fixed to the main body 10 as in the second embodiment. However, since the elastic body 41 is interposed, the roll paper 30 is provided. The core opening 32 can be easily inserted into the support portion 13, and the roll paper 30 can be fixed to the main body 10 by pressing the core opening 32 after insertion by the restoring force of the elastic body 41. .

  Next, the roll paper storage container 1 which concerns on Example 4 of this invention is demonstrated. Similar to the configuration of the third embodiment, the roll paper storage container 1 according to the fourth embodiment is characterized in that an elastic body 42 is further provided on at least a part of the outer edge of the support portion 13. However, the elastic body 42 of the present embodiment is different in the configuration and structure of the elastic body 41 of the third embodiment. Specifically, as shown in FIG. 5, the elastic body 42 of Example 4 has a hollow cylindrical shape or a hollow barrel shape as a whole, and a plurality of openings 421 extending in the longitudinal direction are provided in the circumferential direction. It has a structure. Therefore, the elongated pillars 422 are provided between the openings 421, and the plurality of pillars 422 exhibit desired elasticity and flexibility for attaching and fixing the roll paper 30.

  Examples of the material of the elastic body 42 configured as described above include resin, rubber-based material, silicon-based material, and the like. However, a metal-based material may be used as long as it has the desired elasticity. Further, since the elastic body 42 of the fourth embodiment is longer in the longitudinal direction (axial direction) than the elastic body 41 of the third embodiment, before the roll paper 30 is received, the support portion 13 of the main body 10 is previously coated with an adhesive or the like. It is preferable to adhere.

  By adopting Example 4 having such a configuration, similarly to Example 3, the elastic body 42 is interposed, so that the core opening 32 of the roll paper 30 can be easily inserted into the support part 13, The roll paper 30 can be fixed to the main body 10 by pressing the core opening 32 after insertion by the restoring force of the elastic body 42.

  The roll paper storage container of the present invention is rich in design as well as functionality and cost performance. Furthermore, there is no additional work such as extraction of the core material when using the roll paper, and the roll paper can be easily taken out and cut. Therefore, the roll paper storage container of the present invention has very high industrial applicability.
