Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in the refill cases disclosed in each of the above-mentioned patent documents, in any case, with the refill outlet open, an operation of tilting the case body is required so that the outlet faces slightly downward. Then, the refill to be used is taken out by utilizing the fact that the refill comes out of the case body to the outlet by its own gravity. According to this, delicate operations such as rocking the case body while adjusting the inclination of the case body are required. For this reason, more refills than necessary, or all the refills in the case body may jump out from the outlet and scatter on the floor surface, and there may also be cases where the work of picking up the refills scattered on the floor surface is forced.

[0006] The present invention has been made paying attention to the above-mentioned problems of the conventional refill case, and it is an object of the present invention to provide a refill case that can easily take out the required refill without turning the refill outlet downward and solves the problems of the conventional ones such as a large amount of refills jumping out of the case body at the same time.

Means for Solving the Problems

[0007] The refill case according to the present invention made to solve the above problems is formed with a U-shaped cross section perpendicular to the longitudinal direction by a back plate and left and right foot plates, and the inner space surrounded by the U-shape is used as a refill storage chamber. A case body is formed with a lid portion on the tip side and a case portion on the rear side through a bendable thin portion provided near the tip portion in the longitudinal direction of the back plate. A front plate, left and right outer foot plates form a U-shaped cross section perpendicular to the longitudinal direction, cover the refill storage chamber on the case body side with the front plate, and position the foot plates of the case body inside the outer foot plates to support the case body slidably in the longitudinal direction. A cover member is provided. A guide body is formed along the longitudinal direction on either one of at least one of the foot plates in the lid portion and the outer foot plate on the cover member side covering the foot plate, and a sliding body in contact with the guide body is formed on the other. An operation portion protruding outside the foot plate is provided on the case body, and by relatively moving the operation portion with respect to the longitudinal direction of the cover member, a slide operation of feeding out the lid portion of the case body from the tip portion of the cover member is realized.

[0008] In this case, in a preferred embodiment, an inner lid is further provided which is attached to the left and right foot plates of the case body and covers the refill storage chamber on the front side. Protrusions for avoiding surface contact with the stored refill are provided on the inner surface on the refill storage chamber side of the back plate of the case body and the inner surface on the refill storage chamber side of the inner lid respectively. A pair of protection plates are formed on the inner lid so as to be respectively positioned inside the left and right foot plates from the thin portion of the case body to the lid portion, and are configured to give a turning operation of bending the lid portion to the back side through the thin portion by the sliding contact of the sliding body with respect to the guide body.

[0009] Furthermore, the guide body is formed to protrude in a rail shape extending along the longitudinal direction outside the foot plate of the lid body portion, and the sliding body is formed to protrude so as to be in contact with the guide body at the tip of the cover member from which the lid body portion is drawn out by the sliding operation. A parallel region parallel to the back plate is formed on the guide body on the tip side, and an inclined region that is separated from the back plate is formed following the parallel region toward the thin-walled portion side. In the first half of the sliding operation, an operation of feeding out the lid body portion from the tip of the cover member is given without giving a rotational operation to the lid body portion, and in the second half of the sliding operation, a rotational operation that warps the lid body portion toward the back side is configured to be given.

Advantages of the Invention

[0010] According to the refill case according to the present invention described above, a case body in which a lid body portion and a case portion are formed via a bendable thin-walled portion is slidably mounted in a cover member to form a refill case. And, a guide body and a sliding body that can be slidably contacted with each other by a sliding operation are provided on either one and the other of the lid body portion and the cover member side, so that a rotational operation that warps the lid body portion of the case body from the tip of the cover member toward the back side is given along with the sliding operation.

[0011] Therefore, due to the rotational operation of the lid body portion by the thin-walled portion, the tip of the refill is exposed from the case portion, so that the required refill can be easily taken out. Therefore, it is possible to provide a refill case that can solve the problems of conventional ones such as being able to take out the refill without facing the refill outlet downward and a large amount of refill jumping out simultaneously from the case body side.

[0012] In this case, an operation part protruding outside the foot plate is provided on the case body, and by relatively moving the operation part with respect to the longitudinal direction of the cover member, a slide operation for extending the lid part of the case body from the tip part of the cover member is possible. Therefore, by using the operation part, the slide operation on the case body side with respect to the cover member can be easily realized, and a replacement core case with excellent operability can be provided.

[0013] Furthermore, an inner lid that covers the replacement core accommodation chamber on the front side is further attached to the case body side, and protrusions that avoid surface contact with the replacement core are respectively formed on the case body side and the inner surface of the inner lid, so that the problem that the replacement core adheres to the inside of the replacement core accommodation chamber due to static electricity can be effectively solved. According to this, since the case body and the inner lid are formed of two parts, the problem of damaging the opposing protrusions by forced extraction during mold release can be avoided compared to the case where protrusions are respectively formed on the opposing inner surfaces by one part.

[0014] In addition, since the inner lid adopts a configuration in which a pair of protection plates located from the thin-walled part to the lid part of the case body are respectively formed inside the left and right foot plates of the case body, when the lid part extended by the slide operation is returned into the cover member, the problem that the replacement core is sandwiched between the foot plate on the lid part side warped to the back side and the foot plate on the case part side can be effectively solved.

[0015] Regarding other effects according to this invention, they will be described each time together with the description of the embodiments in the column of the mode for carrying out the invention.

Embodiments for Carrying Out the Invention

[0017] The refill case according to this invention will be described with reference to the drawings. FIGS. 1 and 2 show the overall configuration of the refill case as seen from the front surface side of the cover member 1 and the back surface side of the case body 2. In this embodiment, the cover member 1 and the case body 2 are formed of a resin material. Further, the inner lid 3 which is attached to the case body 2 described later and covered by the cover member 1 is also formed of a resin material. And, the case body 2 and the inner lid 3 are attached to the cover member 1 so as to be slidable along the longitudinal direction with respect to the cover member 1, thereby constituting a refill case. In the following, for the sake of convenience of explanation, one longitudinal direction in which the lid portion 2e of the case body 2 described later is drawn out from the cover member 1 will be referred to as the front end portion, and the other will be referred to as the rear portion.

[0018] In FIGS. 11 to 18, the individual configurations of the case body 2, the inner lid 3, and the cover member 1 described above are shown. First, based on the respective figures showing these individual configurations, the detailed configurations of each member will be described. FIGS. 11 and 12 show the case body 2. This case body 2 is formed such that a cross section orthogonal to the longitudinal direction is U-shaped by a back plate 2a and left and right leg plates 2b, and a refill housing chamber 2c is formed in the inner space surrounded by the U-shape.

[0019] Further, via a bendable thin portion 2d provided near the front end portion in the longitudinal direction of the back plate 2a, a lid portion 2e is formed on the front end side, and a case portion 2f is formed on the rear portion side. And, a closing plate 2g that connects the left and right leg plates 2b and closes the front end portion of the lid portion 2e is formed on the lid portion 2e, and a rear closing plate 2h that connects the left and right leg plates 2b and closes the rear portion of the case portion 2f is formed at the rear of the case portion 2f.

[0020] On the outer sides of the left and right leg portions 2b of the lid portion 2e, a pair of guide bodies 2j are respectively formed to protrude in a rail shape along the longitudinal direction. As shown in FIG. 12, in the guide body 2j, a parallel region 2j1 parallel to the back plate 2a is formed on the front end side of the lid portion 2e, and following this parallel region 2j1, an inclined region 2j2 that moves away from the back plate 2a toward the thin portion 2d side is formed. Incidentally, the above-described parallel region 2j1 and inclined region 2j2 of the guide body 2j act so as to give a pivoting operation that warps the lid portion 2e of the case body 2 toward the back side through the above-described thin-walled portion 2d by being in sliding contact with a sliding body 1g provided on the cover member 1 side as the cover member 1 slides out the lid portion 2e of the case body 2 from the tip end portion of the cover member 1 to be described later.

[0021] On the left and right leg plates 2b of the case portion 2f described above, fitting recesses 2k for attaching an inner lid 3 to be described later are formed at substantially the center in the longitudinal direction and near the lid portion 2e. Also, on both outer sides of the left and right leg plates 2b of the case portion 2f, a pair of slide protrusions 2m are formed along the longitudinal direction of the case body 2. These slide protrusions 2m engage with a case support portion 1d to be described later provided on the cover member 1, and act so that the case body 2 is slidably supported in the longitudinal direction.

[0022] Also, near the rear of the left and right leg plates 2b of the case portion 2f, rib-shaped click protrusions 2n are formed. When the cover member 1 slides with respect to the case body 2, these click protrusions 2n overcome a click body 1f formed on the case body 2 side, thereby generating a click action. Therefore, this click action also occurs when the case body 2 is returned into the cover member 1. Furthermore, on the inner surface of the back plate 2a of the case portion 2f on the side of the refill storage chamber 2c, a plurality of protrusions 2p for avoiding surface contact with the stored refill L are formed perpendicular to the longitudinal direction of the case body 2. This serves to prevent the refill L from being adsorbed and sticking due to static electricity on the inner surface of the refill storage chamber 2c of the case body 2 formed of a resin material.

[0023] Also, near the above-described thin-walled portion 2d on the left and right leg plates 2b of the case portion 2f, a pair of operation portions 2t protruding outward from the leg plates 2b are integrally formed with the case body 2. This pair of operation parts 2t is configured to facilitate a slide operation for relatively moving the case body 2 with respect to the cover member 1 in a state where the case body 2 is slidably attached to the cover member 1. That is, by relatively moving the operation part 2t with respect to the longitudinal direction of the cover member 1, a slide operation for feeding out the lid part 2e of the case body 2 from the tip part of the cover member 1 can be realized.

[0024] Furthermore, on the back side of the back plate 2a of the case body 2, as shown in FIG. 2, a recessed part 2q is formed along the longitudinal direction of the rear half part, and a large number of linear protrusion groups 2r arranged in a direction orthogonal to the longitudinal direction of the case body 2 are formed in the recessed part 2q. And, on the tip part side of the recessed part 2q, an arrow mark 2s having a preferably triangular shape is formed. The arrow mark 2s indicates the slide direction of the case body 2 side with respect to the cover member 1, and the protrusion group 2r functions as a slip prevention for fingertips in the slide operation.

[0025] FIGS. 13 to 15 show a single-component configuration of an inner lid 3 that is attached to the left and right leg plates 2b of the case body 2 described above and covers the refill accommodation chamber 2c on the front side. This inner lid 3 is formed in a flat shape, and fitting convex parts 3a are formed at the central part in the longitudinal direction and near the tip part. The fitting convex parts 3a are fitted into inner lid fitting recesses 2k formed in the case body 2, and are attached so as to cover the refill accommodation chamber 2c of the case body 2 on the front side.

[0026] At this time, a pair of protection plates 3b formed at the tip part of the inner lid 3 are arranged so as to be positioned from the thin-walled part 2d to the lid part 2e inside the left and right leg plates 2b of the case body 2. Thereby, as described in the column of the effects of the invention, when returning the lid part 2e fed out by the slide operation into the cover member 1, the problem that the refill L is sandwiched between the leg plate 2b on the lid part 2e side warped to the back side and the leg plate 2b on the case part 2f side can be effectively solved.

[0027] Also, at the rear part of the inner lid 3, a pair of spacers 3c formed to protrude from the inner surface of the inner lid 3 act to maintain a constant interval between the inner lid 3 and the back panel 2a of the case body 2 at the rear part of the inner lid 3. Case body 2 Furthermore, a plurality of protrusions 3d are formed on the inner surface of the inner lid 3 in a direction orthogonal to the longitudinal direction of the inner lid 3. In the resin inner lid 3 that covers the refill accommodation chamber 2c of the case part 2f from the front, this is to avoid surface contact with the refill L, and to prevent the refill L from being adsorbed by static electricity and sticking to the inner lid 3.

[0028] Figures 16 to 18 show the single-component structure of the cover member 1. This cover member 1 is formed with a U-shaped cross-section orthogonal to the longitudinal direction by the front panel 1a and the left and right outer side foot plates 1b. At the rear part of this cover member 1, a rear part foot plate 1c that connects the left and right outer side foot plates 1b is formed. And the front panel 1a Case body 2 covers the refill accommodation chamber 2c of the case body 2, and positions the left and right foot plates 2b of the case body 2 inside the left and right outer side foot plates 1b to slidably support the case body 2 in the longitudinal direction. And it is configured such that the lid part 2e of the case body 2 is drawn out from the tip side of the cover member 1 by a sliding operation.

[0029] Note that guide recesses 1m are formed along the left and right outer side foot plates 1b near the tip parts of the left and right outer side foot plates 1b of the cover member 1 in a state where a part of each outer side foot plate 1b is cut out. These guide recesses 1m are positioned at a pair of operation parts 2t formed on the case body 2 when the case body 2 is attached to the cover member 1, and the operation parts 2t are arranged to be slidable in the guide recesses 1m.

[0030] ​Also, along the edges of the left and right outer foot plates 1b, case support portions 1d are formed at two locations in the longitudinal direction so as to face each other inward. By slidably supporting the left and right slide protrusions 2m formed on the foot plate 2b of the case body 2, the case body 2 is slidably supported, and it also functions to prevent the case body 2 from coming off the cover member 1. And, inside the left and right outer foot plates 1b near the rear portion, a pair of slide protrusions 1e are formed so as to face each other. When the rib-shaped click protrusion 2n formed on the case body 2 gets over it, this generates a click action when the case body 2 is opened. Furthermore, inside the rear portion side of the outer foot plate 1b, a pair of click bodies 1f are formed so as to face each other. When the case body 2 is slid, when the rib-shaped click protrusion 2n formed on the case body 2 gets over it, this click body 1f generates a click action.

[0031] On the other hand, inside the outer foot plate 1b at the tip of the cover member 1, sliding bodies 1g project so as to face each other. When the case body 2 slides and the lid portion 2e projects from the tip of the cover member 1, these pair of sliding bodies 1g contact the parallel region 2j1 and the inclined region 2j2 of the guide body 2j formed on the lid portion 2e, and function to warp the lid portion 2e to the back side. Details of the operation will be described later based on FIGS. 4 to 8 and the like.

[0032] Also, near the rear of the above-described sliding bodies 1g at the tip of the cover member 1, stoppers 1h are provided so as to face each other. When the case body 2 slides and the lid portion 2e is fully opened, the tip of the slide protrusion 2m formed on the foot plate 2b of the case portion 2f abuts (see FIG. 8), and this pair of stoppers 1h stops the sliding operation of the case body 2. Also, in the sliding operation of pulling back the case body 2 into the cover member 1, the pair of stoppers 1h contacts the return guide portion 2j3 of the guide body 2j and also serves to return the lid portion 2e that is warped to the back side to a state along the longitudinal direction of the case body 2. The operation will be described later based on FIGS. 4 to 8 and the like.

[0033] Furthermore, on the surface of the front panel 1a of the cover member 1, as shown in FIG. 1, a circular depression 1k is formed substantially at the center of the cover member 1. When sliding the case body 2 with respect to the cover member 1, this depression 1k and the linear protrusion group 2r on the case body 2 side can smooth the sliding operation by, for example, placing the thumb on this depression 1k and placing the index finger on the linear protrusion group 2r on the case body 2 side and sliding them relatively. In this sliding operation, the case body 2 can also be slid along the longitudinal direction of the cover member 1 by using the pair of operation portions 2t provided on the case body 2 and protruding from both sides of the cover member 1.

[0034] As shown in FIGS. 1 and 2, in the state where the case body 2 is accommodated in the cover member 1, in the state where the front panel 1a of the cover member 1 is viewed from the front (the state shown in FIG. 1), the closing plate 2g of the lid portion 2e formed at the tip of the case body 2 is visible along the tip recess 1j formed at the tip of the cover member 1. According to this, by making the resin color of the case body 2 substantially the same as the core color of the refill L accommodated in this refill case, the core color accommodated in the refill case can also be identified by the user by coloring the closing plate 2g.

[0035] In this case, by making the density of the resin color for molding the case body 2 vary step by step according to the hardness of the refill L, it is also possible to allow the user to distinguish by the density of the closing plate 2g. The same color mentioned here is the hue in the Munsell color system, indicating within 10 hues and within 3 in lightness and chroma. Also, the density shall be measured for the surface of the part with a densitometer (sakura DENSITO METER PDA65, Konishiroku Photo Industry Co., Ltd.). Also, the hardness of the core indicates the writing hardness measured by the method specified in JIS S 6005:2007.

[0036] Figures 3 to 10 mainly explain the opening and closing operation of the lid body part 2e mainly when the case body 2 is slid with respect to the cover member 1. Figure 3 is a central cross-sectional view (a cross-sectional view taken along line a-a in Figure 2) of the case body 2 with the inner lid 3 attached and accommodated in the cover member 1, and Figure 4 is a cross-sectional view along one guide body 2j part formed in the lid body part 2e at this time (a cross-sectional view taken along line b-b in Figure 2). In the state shown in Figure 4 where the case body 2 is accommodated with respect to the cover member 1, the stopper 1h of the cover member 1 is in contact with the return guide part 2j3 of the guide body 2j. Therefore, the lid body part 2e maintains a closed state along the longitudinal direction of the cover member 1.

[0037] Figures 5 and 6 show a state where the lid body part 2e of the case body 2 protrudes from the tip part of the cover member 1 by about half of the length dimension of the lid body part 2e, and Figure 7 shows the state of the lid body part 2e at this time. That is, in the initial stage (the first half) of protruding the lid body part 2e from the tip part of the cover member 1, the slider 1g on the cover member 1 side slides in contact with the parallel region 2j1 of the guide body 2j formed in the lid body part 2e. For this reason, an operation of feeding out the lid body part 2e from the tip part of the cover member 1 is given to the lid body part 2e without giving a rotating operation. Note that in the state shown in Figure 7, the slider 1g is slightly in contact with the inclined region 2j2 of the guide body 2j, and accordingly, the lid body part 2e is in a state of being slightly warped toward the back side through the thin part 2d.

[0038] As described above, in the initial stage of protruding the lid body portion 2e, the lid body portion 2e is drawn out from the tip of the cover member 1 without applying a rotational motion. Therefore, even if the refill case is carelessly tilted, it is possible to prevent the refill L inside the case from popping out and falling.

[0039] FIG. 8 shows a state where the lid body portion 2e is further drawn out from the cover member 1 and the lid body portion 2e is fully opened. In the latter half of the drawing-out operation of the lid body portion 2e from the state shown in FIG. 7 to the state shown in FIG. 8, as the cover member 1 is drawn out, the sliding body 1g slides along the inclined region 2j2 of the guide body 2j. Therefore, a rapid rotational motion that warps toward the back side is applied to the lid body portion 2e via the thin-walled portion 2d. And in the state shown in FIG. 8 where the lid body portion 2e is fully opened, the tip of the slide protrusion 2m provided along the longitudinal direction of the case body 2 abuts against the stopper 1h, and the drawing-out of the lid body portion 2e is stopped.

[0040] FIGS. 9 and 10 show the external appearance configuration of the refill case in the fully opened state of the lid body portion 2e, and FIG. 10 shows the state where the refill L is accommodated in the case. In the fully opened state of the lid body portion 2e, as shown in FIG. 8, the rear part of the inclined region 2j2 of the guide body 2j is in contact with the sliding body 1g. In this state, the lid body portion 2e can be further arbitrarily warped with a fingertip or the like via the thin-walled portion 2d. Therefore, the required number of refills L can be accurately taken out from the refill case.

[0041] On the other hand, when the lid body portion 2e is slid back into the cover member 1 from the fully opened state of the lid body portion 2e shown in FIGS. 8 to 10, for example, as shown in FIG. 7, the return guide portion 2j3 of the guide body 2j slides on one side stopper 1h. As a result, the lid body portion 2e in the warped state toward the back side is accommodated in the cover member 1 while being returned to the state along the longitudinal direction of the case body 2. A As shown in FIG. 7, for example, the return guide portion 2j3 of the guide body 2j slides on one side stopper 1h. Cover member As a result, the lid body portion 2e in the warped state toward the back side is accommodated in the cover member 1 while being returned to the state along the longitudinal direction of the case body 2. And in the state shown in FIG. 4 where the lid body portion 2e is completely housed within the cover member 1, the return guide portion 2j3 of the guide body 2j Cover member abuts against the stopper 1h on one side, and thus, the lid body portion 2e will maintain a closed state.

[0042] When returning from the fully open state of the lid body portion 2e into the cover member 1, there may occur problems such as pinching a part of the refill L housed in the case between the lid body portion 2e via the thin-walled portion 2d and each foot plate 2b provided on the case portion 2f, causing damage to the refill L. However, as shown in FIG. 9, since the pair of protection plates 3b formed at the tip of the inner lid 3 are positioned inside the foot plates 2b of the lid body portion 2e and the case portion 2f, the problem of damaging the above-described refill L can be avoided.

[0043] In the embodiment of the refill case described above, with the inner lid 3 attached to the case body 2, the case body 2 is slidably attached to the cover member 1. However, the inner lid 3 is not necessarily required and can be omitted. Also, when using the middle lid 3, it can be integrally formed by connecting the middle lid 3 to the rear side of the case body 2 via a thin-walled connecting band (not shown). Then, by folding back the thin-walled connecting band and assembling the inner lid 3 to the case body 2, the number of parts can be reduced, thereby facilitating manufacturing management and providing a refill case that can be made more cost-effective.

Through a bendable thin portion provided near the tip of the back panel in the longitudinal direction, a lid portion is formed on the tip side and a case portion is formed on the rear side, and A front panel and left and right outer foot plates form a U-shaped cross section perpendicular to the longitudinal direction, covering the refill accommodation chamber on the case body side with the front panel, and positioning the foot plates of the case body inside the outer foot plates to support the case body slidably in the longitudinal direction, and a cover member is provided, On at least one of the foot plates in the lid body portion and the outer foot plate on the cover member side covering this foot plate, a guide body is formed along the longitudinal direction, and on the other one, a sliding body that contacts the guide body is formed. An operation portion protruding outside the foot plate is provided on the case body, and by relatively moving the operation portion with respect to the longitudinal direction of the cover member, a sliding operation for feeding out the lid body portion of the case body from the tip portion of the cover member is realized. The guide body is formed in a state of protruding in a rail shape extending along the longitudinal direction outside the foot plate of the lid body portion. The sliding body is formed to protrude so as to contact the guide body at the tip portion of the cover member from which the lid body portion is fed out by the sliding operation. In the guide body, a parallel region parallel to the back plate is formed on the tip portion side, and by forming an inclined region that separates from the back plate toward the thin wall portion side following the parallel region, in the first half of the sliding operation, an operation of feeding out the lid body portion from the tip portion of the cover member is given without giving a rotational operation to the lid body portion, and in the second half of the sliding operation, a rotational operation of warping the lid body portion to the back side is given, which is characterized by a refill case.
