[0018] An embodiment of a paper case will be described below with reference to the drawings. The paper case can store tissue paper, which is sold in a plastic bag, inside and can be displayed in a neat manner. [First embodiment]

[0019] A paper case 11 according to a 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, for example, an opaque synthetic resin material, but may also be made of a transparent or translucent synthetic resin material. The paper case 11 may also be made of a metal material, such as stainless steel.

[0020] As shown in FIGS. 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, excluding legs 14 (described later), is housed inside the first case 12. That is, the second case 13 is movable between a first position P1, where it is fitted into a predetermined position inside the first case 12, and a second position P2, where it is separated from the first case 12, as shown in FIG. 9. The second case 13 fits inside the first case 12 and can engage with the bottom of the first case 12. The second case 13 forms a base that supports the first case 12 and the paper 15. The paper case 11 can store paper 15 in an 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 an outlet 22A (described next).

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

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

[0023] 6 and 7, the pair of first engagement portions 23 is provided on the inner surface of one wall portion 21A of the side wall portions 21 and the inner surface of the other wall portion 21B of the side wall portions 21 opposite to the one wall portion 21A. The pair of first engagement portions 23 is provided on both sides of a protruding portion 26 of the second case 13, which will be described later, sandwiched therebetween.

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

[0025] In this embodiment, the inclined surfaces 24 are provided at positions corresponding to at least a pair of second engagement portions 27. That is, the inclined surfaces 24 are provided in pairs at positions corresponding to a pair of second engagement portions 27. Note that the structure of the inclined surfaces 24 is not limited to this, and the inclined surfaces 24 may be provided around the entire periphery of the lower end portion of the side wall portion 21 excluding the receiving portion 25 and its surrounding area.

[0026] The pair of inclined surfaces 24 are provided on the lower end of the side wall portion 21. The pair of inclined surfaces 24 are provided below (directly below) the first engagement portion 23. The pair of inclined surfaces 24 are provided on the inner surface of one wall portion 21A of the side wall portions 21 and the inner surface of the other wall portion 21B of the side wall portions 21 opposite to the one wall portion 21A. The pair of inclined surfaces 24 are formed obliquely with respect to the extending direction of one of the side wall portions 21 on which they are provided. In other words, as shown in FIG. 7 etc., the pair of inclined surfaces 24 are inclined so that the inner diameter dimension D of the first case 12 increases with increasing distance from the top wall portion 22.

[0027] As shown in FIG. 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 so as to recess outward in a generally rectangular shape from the inner surface of 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 FIGS. 4 and 5 , the receiving portions 25 are formed to be larger than the dimensions of the stopper portion 34 in the movement direction M of the stopper portion 34, as will be described later. Therefore, the receiving portions 25 can allow the stopper portion 34 to move in the movement direction M as the second wall portion 42 moves in a direction approaching a first wall portion 41 of a protruding portion 26 of the second case 13, as will be described later.

[0028] 3 to 8, second case 13 has a raised portion 26 provided in the center, a pair of flat portions 31 extending outward from the end of raised portion 26 opposite the end on top wall 22 side, a pair of finger hooks 32 provided on each of the pair of flat portions 31, a pair of vertical wall portions 33 extending from the outside of each of the pair of flat portions 31 toward top wall 22, a pair of second engagement 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 legs 14 provided on each of the pair of flat portions 31. Second case 13 is integrally molded from the above-mentioned synthetic resin material.

[0029] The raised portion 26 is formed so as to 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 spaced apart from the first wall portion 41, and a connecting portion 43 connecting the first wall portion 41 and the second wall portion 42. The second wall portion 42 is arranged so as to be oblique to the first wall portion 41.

[0030] The lower side of the raised portion 26 is a hollow portion 44. In order to close the hollow portion 44 below the raised portion 26, a separate cover may be provided to cover the hollow portion 44. The cover may be configured to be detachable from the second case 13. The presence of the cover prevents dust and the like from accumulating in the hollow portion 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 a direction in which the second wall portion 42 approaches the first wall portion 41.

[0032] As shown in FIG. 3 , each of the pair of flat portions 31 is formed in a substantially rectangular plate shape. The shape of one flat portion 31 may be substantially the same as or slightly different from the shape of the other flat portion 31. The flat portion 31 has a finger hook 32 formed as a through-hole in approximately its center. The finger hook 32 is formed as, for example, a circular through-hole, but may also be rectangular or polygonal. The configuration of the finger hook 32 of one flat portion 31 may be the same as the configuration of the finger hook 32 of the other flat portion 31, or may be slightly different from the configuration of the finger hook 32 of the other flat portion 31. The pair of flat portions 31 can move in the movement direction M so as to approach or move away from each other when the second wall portion 42 moves in a direction approaching the first wall portion 41.

[0033] The legs 14 are provided at two locations, one at each corner of the pair of flat portions 31. In other words, as shown in FIGS. 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, the paper case 11 is supported by a plurality of legs 14, so that even if the second case 13 is warped due to manufacturing variations, rattles in the paper case 11 are prevented.

[0034] As shown in FIG. 3, a pair of stopper portions 34 are provided on each flat portion 31. The flat portion 31 has a first side 31A on which the vertical wall portion 33 is provided, and a pair of second sides 31B different from the first side 31A. The pair of second sides 31B are provided in positions facing each other. The pair of second sides 31B are provided in positions 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 stopper portion 34 is provided on the other of the pair of second sides 31B.

[0035] 4 and 5, each of the pair of stopper portions 34 is formed as a rectangular protruding piece protruding from the flat portion 31. As shown in FIG. 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 FIGS. 6 to 9 , each of the pair of vertical wall portions 33 is provided to rise from the first side 31A. The shape of one vertical wall portion 33 may be substantially the same as or slightly different from the shape of the other vertical wall portion 33. The vertical wall portion 33 extends in a direction intersecting (orthogonal to) the flat portion 31. The vertical wall portion 33 has a pair of rounded corner portions 46. The pair of rounded corner portions 46 are provided at corner portions near the top wall portion 22 at both ends of the vertical wall portion 33 in the width direction W. The pair of rounded corner portions 46 are formed to remove the corner portions. The pair of rounded corner portions 46 may have any shape, and may be, for example, arc-shaped, or may be formed obliquely relative to the vertical direction to remove the corner portions.

[0037] One of the pair of second engagement portions 27 is provided on one of the pair of vertical wall portions 33, and the other of the pair of second engagement portions 27 is provided on the other of the pair of vertical wall portions 33. As shown in FIGS. 7 to 9, each of the pair of second engagement portions 27 is formed in a mountain shape that protrudes from the vertical wall portion 33. More specifically, the second engagement portion 27 has a mountain shape that is rounded near the top, and the slope of the slope at a position closer to the top wall portion 22 is gentler than the slope at a position farther from the top wall portion 22.

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

[0039] Next, with reference to FIG. 9 and other figures, we will explain how to assemble the paper case 11 by joining the first case 12 and the second case 13. The user removes a stack of paper 15 stored in a plastic bag or similar from the bag or box and places the stack on 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. The raised portion 26 acts as a guide, allowing the first case 12 to be 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 placed over the second case 13 is misaligned with the angle of the second case 13 around the central axis C, the deangled portion 46 of the vertical wall portion 33 abuts against 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, because an inclined surface 24 is provided at the lower end of the side wall 21 of the first case 12, when the second engagement portion 27 of the second case 13 engages with the first engagement portion 23 of the first case 12, the second engagement portion 27 is guided by the inclined surface 24. At this time, the second engagement 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 approach each other. This allows the side wall 21 of the first case 12 to smoothly climb over the second engagement portion 27 of the second case 13, allowing the second engagement portion 27 of the second case 13 to engage with the first engagement portion 23 of the first case 12. The engagement of the second engagement portion 27 with the first engagement portion 23 secures the second case 13 to the first case 12, making assembly of the paper case 11 extremely simple and complete with a single touch.

[0041] At this time, the stopper portions 34 of the second case 13 are inserted into the receiving portions 25 of the first case 12. Because the stopper portions 34 abut against the receiving portions 25, the second case 13 does not enter further back (toward the top wall portion 22) than the first position P1 where it is fitted into the first case 12.

[0042] On the other hand, if the user has used up all the paper 15 and wants to separate the second case 13 from the first case 12 and refill the paper case 11 with paper 15, the user does the following. While holding up the paper case 11, the user inserts, for example, their index finger and thumb into the pair of finger rests 32. Furthermore, they apply force to bring the pair of flat portions 31 closer together. This causes the second wall portion 42 to deform and move closer to the first wall portion 41. This deformation also disengages the second engagement portions 27 from the first engagement portions 23. At this time, because the stopper portions 34 are slidable within the receiving portions 25, the movement of the stopper portions 34 is prevented from being impeded, preventing the second engagement portions 27 from successfully disengaging from the first engagement portions 23.

[0043] In this state, the second case 13 is separated from the first case 12 by pulling the second case 13 out from the first case 12. This causes the second case 13 to move to a second position P2 separated from the first case 12. In this state, the user can add new paper 15 onto the second case 13 (raised portion 26) and, in the same manner as above, place the first case 12 over the top of the second case 13, thereby assembling the first case 12 and the second case 13 together.

[0044] The shapes of the first engagement portion 23 and the second engagement portion 27 are merely examples, and it is of course possible to form the first engagement portion 23 on the first case 12 side as a convex portion and the second engagement portion 27 on the second case 13 side as a concave portion having a complementary shape, instead of the above example. In this case, the inclined surface 24 that guides the first engagement portion 23 is preferably provided, for example, at the tip ends 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 hook portion 32 of one flat portion 31 may be configured as one through-hole, and the finger hook portion 32 of the other flat portion 31 may be configured as two through-holes. This allows the user to attach or detach the second case 13 to or from the first case 12 by inserting the thumb into one through-hole of the finger hook portion 32 of one flat portion 31 and the index finger and middle finger into the two through-holes of the finger hook portion 32 of the other flat portion 31 and applying force to bring the pair of flat portions 31 closer to each other. This can be done.

[0046] According to this embodiment, the following can be said: The paper case 11 comprises a box-shaped first case 12 having side walls 21, a top wall 22, an outlet 22A provided in the top wall 22 through which the paper 15 can be taken out, and a pair of first engagement portions 23 provided in the side wall 21; a second case 13 having a raised portion 26 that is convex toward the top wall 22 so as to be able to support the paper 15, a pair of flat portions 31 extending outward from an end of the raised portion 26 opposite an end thereof close to the top wall 22, a pair of finger hooks 32 provided in approximately the center of the pair of flat portions 31, a pair of vertical wall portions 33 extending from the outside of each of the pair of flat portions 31 toward the top wall 22, and a pair of second engagement portions 27 provided on each of the pair of vertical wall portions 33 and engageable with the pair of first engagement portions 23, wherein at least the raised portion 26 is accommodated within the first case 12. The raised portion 26 has a first wall portion 41, a second wall portion 42 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 that the second wall portion 42 can rotate in a direction approaching the first wall portion 41.

[0047] According to this configuration, when a user places their fingers on the finger hook 32 provided in the approximate center of the flat portions 31 and moves the pair of flat portions 31 closer to each other, 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 so as to move closer to each other. Because the finger hook 32 is provided in the approximate center of the flat portions 31, the user does not need to significantly increase the distance between, for example, their index finger and thumb when placing their fingers on the finger hook 32, making it easy to remove the second case 13 from the first case 12. This also makes it easy to assemble the first case 12 and the second case 13. According to the above configuration, the raised portion 26 serves both as a portion that supports the paper 15 and as a spring structure that allows the pair of flat portions 31 to expand and contract. This simplifies the structure of the paper case 11, reducing the number of parts and manufacturing costs. Furthermore, with the above configuration, the raised portion 26 can hold the paper 15 in a roughly inverted "V" shape, so the installation area for the paper case 11 can be made smaller than that of a regular paper case made of a bag or box. This makes it possible to realize a paper case 11 that can be easily installed in places where installation space is limited, such as a bathroom.

[0048] In this case, the second case 13 is movable between a first position P1 in which it is fitted into a predetermined position inside the first case 12 and a second position P2 in which it is 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 and can 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 different from the side on which the vertical wall portion 33 of the flat portion 31 is provided.

[0049] When the flat portions 31 move in accordance with deformation that brings the second wall portion 42 closer to the first wall portion 41, the side on which the pair of vertical wall portions 33 is provided also moves in a direction away from the first case 12. With the above configuration, even when deformation occurs that brings the second wall portion 42 closer to the first wall portion 41, the stopper portion 34 can be positioned in an operable position. This makes it possible to prevent the second case 13 from entering the inside of the first case 12 more than necessary.

[0050] In this case, the lower end of the side wall portion 21 has a receiving portion 25 that can receive the stopper portion 34, and is formed larger than the dimensions of the stopper portion 34 in the movement direction M of the stopper portion 34, which moves as the second wall portion 42 moves toward the first wall portion 41, and has a receiving portion 25 that allows the stopper portion 34 to move in the movement direction M.

[0051] According to this configuration, the stopper portion 34 can prevent the second wall portion 42 from being hindered from moving in the direction approaching the first wall portion 41.

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

[0053] This configuration makes it possible to make the stopper portion 34 invisible from the outside, thereby improving the appearance of the paper case 11.

[0054] The lower end of the side wall portion 21 has an inclined surface 24 provided in a position corresponding to at least a pair of second engagement portions 27 near a pair of first engagement portions 23, and the inclined surface 24 is inclined so that the inner diameter dimension of the first case 12 increases as it moves away from the top wall portion 22.

[0055] According to this configuration, the pair of second engagement portions 27 can be smoothly guided by the inclined surface 24, and the pair of second engagement portions 27 can be smoothly engaged with the pair of first engagement portions 23.

[0056] Each of the pair of vertical wall portions 33 has a pair of removed corner portions 46 provided at corners at both ends in the width direction W and near the top wall portion 22, and formed to remove the corners.

[0057] According to this configuration, when second case 13 is inserted into first case 12 and placed therein, it is possible to prevent the corners from getting caught on first case 12, which can be a problem.

[0058] Each of the pair of removed corner portions 46 is formed in an arc shape.

[0059] According to this configuration, when inserting the second case 13 into the first case 12 to fit the second case 13, it is possible to prevent the corners from getting caught on the first case 12, and even if the angle of the first case 12 is misaligned with the second case 13, it is possible to fine-tune the angle of the first case 12 and correctly join the first case 12 to the second case 13.

[0060] Each of the pair of finger grips 32 was circular.

[0061] According to this configuration, when the user places his / her finger on the finger rest 32 and deforms the second wall 42 so as to approach the first wall 41, it is possible to prevent strain from being placed on the user's finger.

[0062] Second case 13 is housed within first case 12. This configuration reduces the possibility that second case 13 will become dirty during use. As a result, when cleaning, the user only needs to clean first case 12, and can avoid the trouble of cleaning second case 13, which is less likely to be dirty.

[0063] In the following embodiment, differences from the first embodiment will be mainly described, and illustrations or descriptions of parts common to the first embodiment will be omitted. [Second embodiment]

[0064] A paper case 11 of a second embodiment will be described with reference to Fig. 10. In this embodiment, the shape of the raised portion 26 is different from that of the first embodiment.

[0065] The raised portion 26 is formed in an inverted U-shape and 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] Similar to the first embodiment, the connecting portion 43 is formed in an arch shape with an arcuate cross section. The connecting portion 43 connects the first wall portion 41 and the second wall portion 42 so as to be rotatable in a direction in which 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, the internal space 16 is smaller than that of the paper case 11 of the first embodiment, and the number of sheets of paper 15 that can be stored is reduced, but it is possible to realize a paper case 11 that does not pose a problem in practical use. Also, in order to make it easier to remove the mold from the second case 13, it is of course possible to configure the first wall portion 41 and the second wall portion 42 at a slight angle relative to the flat portion 31 so that they widen as they approach the flat portion 31, rather than configuring the first wall portion 41 and the second wall portion 42 to be completely parallel. [Third embodiment]

[0068] A 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, which improves the durability of the first case 12 and improves the product reliability of the paper case 11. In addition, the paper case 11 can be designed with rounded edges, which improves the appearance of the paper case 11. [Fourth embodiment]

[0071] A paper case 11 according to a fourth embodiment will be described with reference to Fig. 14. In this embodiment, the shape of the pair of vertical walls 33 is different from that of the first embodiment. Also, in this embodiment, the stopper portion 34 and the receiving portion 25 are omitted.

[0072] Each of the pair of vertical wall portions 33 is configured to be longer in the up-down direction than the vertical wall portions 33 of the first embodiment. Therefore, when the second case 13 is in the first position P1 housed within 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. Therefore, in this embodiment, even without the stopper portion 34 and the receiving portion 25, the second case 13 does not slip too deeply into the first case 12. As a result, in this embodiment, the stopper portion 34 and the receiving portion 25 are 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] A paper case 11 according to a fifth embodiment will be described with reference to Figure 15. 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 arranged outside the first case 12. This embodiment also differs from the first embodiment in that a first engagement portion 23 is provided on the outer surface of the side wall portion 21 of the first case 12, and a second engagement portion 27 is provided on the inner surface of the vertical wall portion 33 of the second case 13. Furthermore, this embodiment does not include the stopper portion 34 and the receiving portion 25.

[0075] The vertical wall portion 33 is disposed 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 of this embodiment, there is no risk of the second case 13 getting too 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 above-described embodiment can be embodied with various substitutions and modifications, and the above-described embodiments can also be combined appropriately to form the present invention. [Explanation of symbols]
