[0018] An embodiment of the paper case will be described below with reference to the drawings. The paper case can store, for example, tissue paper sold in plastic bags, inside and present it in an aesthetically pleasing manner. [First Embodiment]

[0019] The paper case 11 of the first embodiment will be described with reference to Figures 1 to 9. As shown in Figure 1, the paper case 11 is made of a synthetic resin material, such as ABS resin, polystyrene, or polypropylene. The paper case 11 is made of an opaque synthetic resin material, for example, but may be made of a transparent or translucent synthetic resin material. The paper case 11 may be made of a metal material, such as stainless steel.

[0020] As shown in Figures 1 to 3, the paper case 11 has an upper first case 12 and a lower second case 13. The first case 12 is box-shaped. Most of the second case 13, except for the legs 14 which will be described later, is housed inside the first case 12. That is, the second case 13 is movable between a first position P1, which is fitted into a predetermined position inside the first case 12, and a second position P2, which is separated from the first case 12 as shown in Figure 9. The second case 13 can be fitted inside the first case 12 and engage with the bottom of the first case 12. The second case 13 constitutes the base portion that supports the first case 12 and the paper 15. The paper case 11 can store the paper 15 in the internal space 16 formed by the first case 12 and the second case 13. The paper 15 is taken out one sheet at a time from the dispensing opening 22A which will be described next and used.

[0021] As shown in Figures 1 to 8, the first case 12 has a house-like shape with a triangular roof (an inverted home plate shape when viewed from the front). The first case 12 has side walls 21 surrounding the perimeter (four sides) of the second case 13, a top wall 22 covering the top of the second case 13, an outlet 22A provided on the top wall 22, a pair of first engaging parts 23 for engaging with the second case 13, a pair of inclined surfaces 24 provided near the pair of first engaging parts 23, and a receiving part 25 provided on the side walls 21 for receiving the stopper part 34 of the second case 13, which will be described later. The first case 12 is integrally molded from the synthetic resin material described above.

[0022] The side wall portion 21 is formed in the shape of a square frame when viewed from above. The top wall portion 22 is formed in the shape of a triangular roof when viewed from the front. The outlet 22A is formed as a horizontally elongated through-hole that crosses the triangular roof of the top wall portion 22. The outlet 22A is an elongated hole with rounded ends at both ends of the through-hole.

[0023] As shown in Figures 6 and 7, the pair of first engaging portions 23 are provided on the inner surface of one wall portion 21A of the side wall portion 21 and on the inner surface of the other wall portion 21B of the side wall portion 21 that is opposite to the said wall portion 21A. The pair of first engaging portions 23 are also provided on both sides of the raised portion 26 of the second case 13, which will be described later.

[0024] Each of the pair of first engaging portions 23 is formed as a recess with a shape complementary to the second engaging portion 27 of the second case 13, which will be described later.

[0025] In this embodiment, the inclined surface 24 is provided at a position corresponding to at least one pair of second engaging portions 27. That is, the inclined surface 24 is provided in a pair at a position corresponding to the pair of second engaging portions 27. However, the structure of the inclined surface 24 is not limited to this, and it may be provided so as to extend around the entire circumference of the lower end of the side wall portion 21, excluding the receiving portion 25 and its vicinity.

[0026] A pair of inclined surfaces 24 are provided at the lower end of the side wall portion 21. The pair of inclined surfaces 24 are provided below (directly below) the first engaging portion 23. The pair of inclined surfaces 24 are provided on the inner surface of one wall portion 21A of the side wall portion 21 and on the inner surface of the other wall portion 21B of the side wall portion 21 that is opposite to the said wall portion 21A. The pair of inclined surfaces 24 are formed obliquely with respect to the direction in which one of the side wall portions 21 on which they are provided extends. That is, as shown in Figure 7, the pair of inclined surfaces 24 are obliquely oriented such that the inner diameter dimension D of the first case 12 widens as it moves away from the top wall portion 22.

[0027] As shown in Figure 3, the receiving portions 25 are provided at four locations on the lower end of the side wall portion 21. Each of the receiving portions 25 is formed to be recessed in a substantially rectangular shape from the inner surface outward from the lower end of the side wall portion 21. The receiving portions 25 are provided within the thickness of the side wall portion 21. As shown in Figures 4 and 5, the receiving portions 25 are formed to be larger than the dimensions of the stopper portion 34 with respect to the movement direction M of the stopper portion 34, as will be described later. Therefore, the receiving portions 25 can allow the movement of the stopper portion 34 in the movement direction M as the second wall portion 42 moves in a direction toward the first wall portion 41 of the raised portion 26 of the second case 13, which will be described later.

[0028] As shown in Figures 3 to 8, the second case 13 has a raised portion 26 in the center, a pair of flat portions 31 extending outward from the end of the raised portion 26 opposite to the end on the top wall portion 22 side, a pair of finger grips 32 provided on each of the pair of flat portions 31, a pair of vertical wall portions 33 extending toward the top wall portion 22 from the outside of each of the pair of flat portions 31, a pair of second engaging portions 27 provided on each of the pair of vertical wall portions 33, a stopper portion 34 provided on each of the pair of flat portions 31, and a leg portion 14 provided on each of the pair of flat portions 31. The second case 13 is integrally molded from the synthetic resin material described above.

[0029] The raised portion 26 is formed to be convex toward the top wall portion 22. The raised portion 26 can directly support the paper 15. The raised portion 26 is formed, for example, in an inverted "V" shape. The raised portion 26 has a flat first wall portion 41, a flat second wall portion 42 provided spaced apart from the first wall portion 41, and a connecting portion 43 that connects the first wall portion 41 and the second wall portion 42. The second wall portion 42 is provided at an angle to the first wall portion 41.

[0030] The area below the raised portion 26 is a cavity 44. To close off the cavity 44 below the raised portion 26, a separate cover may be provided to cover the cavity 44. This cover may be configured to be detachable from the second case 13. The presence of this cover prevents dust and other debris from accumulating in the cavity 44.

[0031] The connecting portion 43 is formed in an arch shape with a circular arc cross-section. The connecting portion 43 connects the first wall portion 41 and the second wall portion 42 so as to be rotatable in the direction that the second wall portion 42 approaches the first wall portion 41.

[0032] As shown in Figure 3, each of the pair of flat sections 31 is formed in a substantially rectangular flat plate shape. The shape of one flat section 31 may be substantially the same as the shape of the other flat section 31, or it may be slightly different from the shape of the other flat section 31. The flat section 31 has a finger rest 32 formed as a through hole in its substantially central part. The finger rest 32 is formed as, for example, a circular through hole, but it may also be square or polygonal. The configuration of the finger rest 32 of one flat section 31 may be the same as the configuration of the finger rest 32 of the other flat section 31, or it may be slightly different from the configuration of the finger rest 32 of the other flat section 31. The pair of flat sections 31 can move in the direction of movement M such that they move closer to each other or further apart when the second wall section 42 moves closer to the first wall section 41.

[0033] The legs 14 are provided at two locations on each corner of the pair of flat sections 31. In other words, as shown in Figures 3 to 5, the legs 14 are provided at a total of four locations corresponding to the corners of the second case 13. The legs 14 are formed in a substantially hemispherical shape. In this embodiment, since the paper case 11 is supported by multiple legs 14, even if the second case 13 warps or the like due to manufacturing variations, the paper case 11 is prevented from becoming loose.

[0034] As shown in Figure 3, a pair of stopper portions 34 are provided on each of the flat portions 31. The flat portion 31 has a first side 31A with a vertical wall portion 33, and a pair of second sides 31B that are different from the first side 31A. The pair of second sides 31B are located opposite each other. The pair of second sides 31B are located adjacent to the first side 31A. One of the stopper portions 34 is provided on one of the pair of second sides 31B, and the other of the stopper portion 34 is provided on the other of the pair of second sides 31B.

[0035] As shown in Figures 4 and 5, each of the pair of stopper portions 34 is formed as a protruding piece that extends rectangularly from the flat portion 31. As shown in Figure 3, the pair of stopper portions 34 are provided on both sides of the flat portion 31. Each of the pair of stopper portions 34 can be inserted into each of the pair of receiving portions 25 of the first case 12.

[0036] As shown in Figures 6 to 9, each of the pair of vertical wall sections 33 is provided to rise from the first side 31A. The shape of one vertical wall section 33 may be substantially the same as the shape of the other vertical wall section 33, or it may be slightly different from the shape of the other vertical wall section 33. The vertical wall sections 33 extend in a direction that intersects (orthogonal to) the flat section 31. The vertical wall section 33 has a pair of angle-removing sections 46. The pair of angle-removing sections 46 are provided at the corners at both ends of the width direction W of the vertical wall section 33, close to the top wall section 22. The pair of angle-removing sections 46 are formed to remove the corners. The shape of the pair of angle-removing sections 46 may be any shape; for example, they may be arc-shaped, or they may be formed in an oblique direction that is slanted to the vertical direction to remove the corners.

[0037] One of the pair of second engaging portions 27 is provided on one of the pair of vertical wall portions 33, and the other of the pair of second engaging portions 27 is provided on the other of the pair of vertical wall portions 33. As shown in Figures 7 to 9, each of the pair of second engaging portions 27 is formed in a mountain shape that rises from the vertical wall portion 33. More specifically, the second engaging portion 27 has a rounded mountain shape near its top, and the slope of the mountain shape closer to the top wall portion 22 is gentler than the slope of the mountain shape further away from the top wall portion 22.

[0038] In this embodiment, the paper 15 is made of, for example, tissue paper. The paper 15 may also be a paper towel or the like.

[0039] Next, referring to Figure 9, etc., the assembly of the paper case 11 that connects the first case 12 and the second case 13 will be described. The user takes the bundle of paper 15 stored in a plastic bag or the like out of the plastic bag or box and places the bundle on top of the raised portion 26 of the second case 13. In this state, the first case 12 is placed over the second case 13 and the paper 15 from above. At this time, the raised portion 26 acts as a guide, so that the first case 12 is placed over the second case 13 in the correct position. At this time, the pair of vertical wall portions 33 act as a second guide. That is, if the angle of the first case 12 that is placed over the second case 13 is shifted relative to the angle of the second case 13 around the central axis C, the angle removal portion 46 of the vertical wall portion 33 comes into contact with the lower end and inner surface of the side wall portion 21 of the first case 12, guiding the first case 12 to the correct angle. This allows the first case 12 to be placed over the second case 13 at the correct angle.

[0040] Furthermore, since an inclined surface 24 is provided at the lower end of the side wall portion 21 of the first case 12, when the second engaging portion 27 of the second case 13 engages with the first engaging portion 23 of the first case 12, the second engaging portion 27 is guided by the inclined surface 24. At that time, the second engaging portion 27 receives a reaction force from the inclined surface 24, causing the raised portion 26 to deform slightly so that the first wall portion 41 and the second wall portion 42 come closer together. As a result, the side wall portion 21 of the first case 12 smoothly moves over the second engaging portion 27 of the second case 13, and the second engaging portion 27 of the second case 13 can engage with the first engaging portion 23 of the first case 12. With the second engaging portion 27 engaging with the first engaging portion 23, the second case 13 is fixed to the first case 12, and the assembly of the paper case 11 can be completed extremely easily and with a single touch.

[0041] At this time, each stopper portion 34 of the second case 13 is inserted into each receiving portion 25 of the first case 12. Because the stopper portions 34 come into contact with the receiving portions 25, the problem of the second case 13 going further inward (towards the top wall portion 22) than the first position P1 in which it is fitted into the first case 12 does not occur.

[0042] On the other hand, if the user has used up all of the paper 15 and wants to separate the second case 13 from the first case 12 and replenish the paper 15 in the paper case 11, they should do the following: The user lifts the paper case 11 and inserts, for example, their index finger and thumb into the pair of finger rests 32. They then apply force to bring the pair of flat parts 31 closer together. This deforms the paper case so that the second wall 42 moves closer to the first wall 41. This deformation also releases the engagement of each second engagement part 27 with each first engagement part 23. At this time, since each stopper part 34 is slidable within each receiving part 25, the movement of the stopper part 34 is prevented from being obstructed, which would prevent the disengagement of each second engagement part 27 with each first engagement part 23 from working properly.

[0043] In this state, the second case 13 is separated from the first case 12 by pulling the second case 13 out of the first case 12. As a result, the second case 13 moves to the second position P2, which is separated from the first case 12. In this state, the user can add more paper 15 to the second case 13 (raised portion 26) and, as described above, place the first case 12 over the top of the second case 13 to assemble the first case 12 and the second case 13 as a single unit.

[0044] Note that the shapes of the first engaging portion 23 and the second engaging portion 27 are examples, and it is certainly possible to form the first engaging portion 23 on the first case 12 side as a convex portion and the second engaging portion 27 on the second case 13 side as a concave portion with a complementary shape, unlike the above example. In this case, it is preferable that the inclined surface 24 that guides the first engaging portion 23 is provided, for example, at the tip of the pair of vertical wall portions 33 of the second case 13, on the side facing the side wall portion 21.

[0045] Alternatively, the finger rest 32 of one flat portion 31 may be configured as a single through-hole, and the finger rest 32 of the other flat portion 31 may be configured as two through-holes. This allows the user to insert their thumb into the single through-hole of the finger rest 32 of one flat portion 31, and their index and middle fingers into the two through-holes of the finger rest 32 of the other flat portion 31, and apply force to bring the pair of flat portions 31 closer together, thereby attaching and detaching the second case 13 to the first case 12. It is possible.

[0046] According to this embodiment, the following can be said. The paper case 11 comprises a box-shaped first case 12 having a side wall portion 21, a top wall portion 22, an outlet 22A provided on the top wall portion 22 from which the paper 15 can be removed, and a pair of first engaging portions 23 provided on the side wall portion 21; and a second case 13 having a raised portion 26 that is convex toward the top wall portion 22 so as to be able to support the paper 15, a pair of flat portions 31 that extend outward from the end of the raised portion 26 opposite to the end near the top wall portion 22, a pair of finger grips 32 provided in the approximate center of the pair of flat portions 31, a pair of vertical wall portions 33 that extend toward the top wall portion 22 from the outside of each of the pair of flat portions 31, and a pair of second engaging portions 27 provided on each of the pair of vertical wall portions 33 so as to be able to engage with the pair of first engaging portions 23, and in which at least the raised portion 26 is housed inside the first case 12. The raised portion 26 includes a first wall portion 41, a second wall portion 42 provided spaced apart from the first wall portion 41, and a connecting portion 43 that connects the first wall portion 41 and the second wall portion 42 so as to be rotatable in a direction that brings the second wall portion 42 closer to the first wall portion 41.

[0047] With this configuration, when a user places their finger on the finger rest 32 located approximately in the center of the flat portion 31 and brings the pair of flat portions 31 closer together, elastic deformation occurs in the connecting portion 43, causing the first wall portion 41 and the second wall portion 42 of the raised portion 26 to deform and move closer together. At that time, because the finger rest 32 is located approximately in the center of the flat portion 31, the user does not need to widen the distance between their index finger and thumb, for example, when placing their finger on the finger rest 32, making it easier to remove the second case 13 from the first case 12. Also, assembling the first case 12 and the second case 13 becomes easier. With the above configuration, since the raised portion 26 serves as both a part that supports the paper 15 and a spring structure that allows the distance between the pair of flat portions 31 to expand and contract, the structure of the paper case 11 can be simplified, the number of parts can be reduced, and manufacturing costs can be reduced. Furthermore, with the above configuration, the raised portion 26 can hold the paper 15 in a roughly inverted "V" shape, thus reducing the installation area required for the paper case 11 compared to ordinary bag-type or box-type paper cases. This makes it possible to create a paper case 11 that is easy to install even in places with limited space, such as bathrooms.

[0048] In this case, the second case 13 is movable between a first position P1 fitted into a predetermined position inside the first case 12 and a second position P2 separated from the first case 12, and each of the pair of flat portions 31 has a stopper portion 34 that engages with the side wall portion 21 to prevent the second case 13 from entering a position closer to the top wall portion 22 than the first position P1, and the stopper portion 34 is provided on a side of the flat portion 31 that is different from the side on which the vertical wall portion 33 is provided.

[0049] As the flat sections 31 move together due to deformation that brings the second wall section 42 closer to the first wall section 41, the side on which the pair of vertical wall sections 33 are provided also moves in a direction away from the first case 12. With the above configuration, even if deformation occurs that brings the second wall section 42 closer to the first wall section 41, the stopper section 34 can be positioned in an operable position. This prevents the problem of the second case 13 entering the first case 12 more than necessary.

[0050] In this case, the lower end of the side wall portion 21 is a receiving portion 25 capable of receiving the stopper portion 34, and is formed to be larger than the dimensions of the stopper portion 34 with respect to the direction of movement M of the stopper portion 34 that moves in conjunction with the movement of the second wall portion 42 in the direction approaching the first wall portion 41, and has a receiving portion 25 that allows the movement of the stopper portion 34 in the direction of movement M.

[0051] With this configuration, the stopper portion 34 prevents the movement of the second wall portion 42 in the direction approaching the first wall portion 41 from being obstructed.

[0052] The receiving portion 25 is provided within the thickness of the side wall portion 21.

[0053] This configuration allows the stopper portion 34 to be concealed from external view. This improves the appearance of the paper case 11.

[0054] The lower end of the side wall portion 21 is an inclined surface 24 provided in the vicinity of the pair of first engaging portions 23 and corresponding to at least one pair of second engaging portions 27, and has an inclined surface 24 that is angled such that the inner diameter of the first case 12 widens as it moves away from the top wall portion 22.

[0055] With this configuration, the inclined surface 24 smoothly guides the pair of second engaging portions 27, making it possible to smoothly engage the pair of second engaging portions 27 with the pair of first engaging portions 23.

[0056] Each of the pair of vertical wall sections 33 has a pair of corner removal sections 46 that are provided at both ends in the width direction W and at positions close to the top wall section 22, and are formed to remove the corners.

[0057] This configuration prevents the corners of the first case 12 from catching when inserting the second case 13 into the first case 12 and securing the second case 13.

[0058] Each of the pair of angle-reducing portions 46 is formed in an arc shape.

[0059] With this configuration, when inserting the second case 13 into the first case 12 and securing the second case 13, it is possible to prevent the corners from catching on the first case 12, and even if the angle of the first case 12 is misaligned with that of the second case 13, the angle of the first case 12 can be finely adjusted to correctly connect the first case 12 to the second case 13.

[0060] Each of the pair of finger rests 32 was circular in shape.

[0061] This configuration prevents strain on the user's fingers when the user places their fingers on the finger rest 32 and deforms the device to bring the second wall 42 closer to the first wall 41.

[0062] The second case 13 is housed inside the first case 12. This configuration reduces the possibility of the second case 13 becoming soiled during use. As a result, when cleaning, the user only needs to clean the first case 12, saving the effort of cleaning the less soiled second case 13.

[0063] In the following embodiments, the differences from the first embodiment will be described primarily, and parts common to the first embodiment will not be illustrated or described. [Second Embodiment]

[0064] Referring to Figure 10, the paper case 11 of the second embodiment will be described. In this embodiment, the shape of the raised portion 26 differs from that of the first embodiment.

[0065] The raised portion 26 is formed in an inverted "U" shape. The raised portion 26 has a first wall portion 41 extending in the vertical direction, a second wall portion 42 extending substantially parallel to the first wall portion 41, and a connecting portion 43 connecting the first wall portion 41 and the second wall portion 42.

[0066] The connecting portion 43 is formed in an arch shape with a circular arc cross-section, similar to the first embodiment. The connecting portion 43 connects the first wall portion 41 and the second wall portion 42 so as to be rotatable in the direction that the second wall portion 42 approaches the first wall portion 41. However, the radius of curvature of the connecting portion 43 in this embodiment is larger than the radius of curvature of the connecting portion 43 in the first embodiment.

[0067] According to this embodiment, although the internal space 16 is smaller than that of the paper case 11 of the first embodiment, and the number of papers 15 that can be stored is reduced, a paper case 11 that is practically usable can be realized. Furthermore, in order to make it easier to remove the mold from the second case 13, instead of configuring the first wall portion 41 and the second wall portion 42 to be perfectly parallel, it is also possible to configure the first wall portion 41 and the second wall portion 42 to be slightly angled relative to the flat portion 31 so that they widen as they approach the flat portion 31. [Third Embodiment]

[0068] The paper case 11 of the second embodiment will be described with reference to Figures 11 to 13. In this embodiment, the shape of the top wall portion 22 of the first case 12 is different from that of the first embodiment.

[0069] The top wall portion 22 is formed in a dome shape with a semicircular cross-section.

[0070] According to this embodiment, the rigidity of the first case 12 is higher than that of the paper case 11 of the first embodiment, thereby improving the durability of the first case 12 and enhancing the product reliability of the paper case 11. Furthermore, since the paper case 11 can be given a rounded design, the appearance of the paper case 11 can be improved. [Fourth Embodiment]

[0071] Referring to Figure 14, the paper case 11 of the fourth embodiment will be described. In this embodiment, the shape of the pair of vertical wall portions 33 differs from that of the first embodiment. Also, in this embodiment, the configuration of the stopper portion 34 and the receiving portion 25 is omitted.

[0072] Each of the pair of vertical wall portions 33 is configured to be longer in the vertical direction than the vertical wall portion 33 of the first embodiment. Therefore, when the second case 13 is in the first position P1 where it is housed inside the first case 12, the tip of the vertical wall portion 33 can abut against the inner surface of the top wall portion 22 of the first case 12. For this reason, in this embodiment, even without the stopper portion 34 and the receiving portion 25, the problem of the second case 13 sinking deep into the interior of the first case 12 does not occur. As a result, in this embodiment, the configuration of the stopper portion 34 and the receiving portion 25 is omitted, and the shape of the paper case 11 is simplified.

[0073] According to this embodiment, the following can be said: The tips of the pair of vertical wall portions 33 can abut against the top wall portion 22. With this configuration, the stopper portion 34 and the receiving portion 25 can be omitted, and the shape of the paper case 11 can be simplified. [Fifth Embodiment]

[0074] Referring to Figure 15, the paper case 11 of the fifth embodiment will be described. This embodiment differs from the first embodiment in that the vertical wall portion 33 of the second case 13 is not housed inside the first case 12, but is located outside the first case 12. This embodiment also differs from the first embodiment in that the first engaging portion 23 is provided on the outer surface of the side wall portion 21 of the first case 12, and the second engaging portion 27 is provided on the inner surface of the vertical wall portion 33 of the second case 13. Furthermore, in this embodiment, the configuration of the stopper portion 34 and the receiving portion 25 is omitted.

[0075] The vertical wall portion 33 is positioned outside the side wall portion 21 of the first case 12 and abuts against the outside of the side wall portion 21. Therefore, due to the structure of the paper case 11 in this embodiment, there is no risk of the second case 13 falling deep inside the first case 12, and the stopper portion 34 and the receiving portion 25 can be omitted. According to this embodiment, the configuration of the stopper portion 34 and the receiving portion 25 can be omitted, and the shape of the paper case 11 can be simplified.

[0076] The embodiments described above can be implemented with various substitutions and modifications. Furthermore, it is naturally possible to combine the above embodiments as appropriate to constitute the invention. [Explanation of Symbols]
