Description

[Technical field]

[0001] The present invention relates to a pen case for storing writing implements, which has an engaging and holding structure for an adhesive body. [Background technology]

[0002] The applicant had developed a pen case for storing writing implements that has an adhesive at the bottom and can stand on its own. When storing a tall writing implement such as a pen, the pen case tends to tip over due to the height of the center of gravity, making it difficult to maintain the upright position of the pen case. Therefore, in Patent Document 1, the applicant provided a pen case in which the pen case body and the adhesive are engaged by inserting the insertion part of the adhesive into the insertion hole of the pen case body. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Publication No. 3227250 Summary of the Invention [Problem to be solved by the invention]

[0004] However, pen cases are often made of a material that is relatively light and easily deformed, such as cloth material. When such a material is selected, the pen case of Patent Document 1 has a problem that when the pen case is carried while attached to the surface to be attached, the insertion part comes off from the insertion hole while only the adhesive body is attached to the surface to be attached, and only the pen case body comes off. The main cause of this is that the insertion part at the bottom is deformed and falls off. In addition, when cloth material is selected, the pen case body is light, so it is not stable, and the attachment is easily released when an impact is applied.

[0005] Therefore, the present invention aims to provide a pen case that has an engagement and retention mechanism that makes it difficult for the pen case body to separate from the adhesive body made of a resin material, even if the pen case body is made of a light and easily deformed material such as cloth. It is also an object of the present invention to provide a pen case that can maintain a stable upright state. [Means for solving the problem]

[0006] The pen case of the present invention comprises a pen case main body for storing writing utensils, and an adhesive body having an adhesive portion that engages with the bottom of the pen case main body and is adsorbed to the installation surface, and is characterized in that the bottom of the pen case main body has an engagement holding mechanism using a bottom support portion consisting of a support surface that maintains the engagement state of the adhesive body and suppresses deformation of the bottom surface of the pen case main body.

[0007] In addition, it is preferable that the engagement and retention mechanism uses a fastener having a protruding engagement portion that protrudes from the adhesive body and reaches the bottom of the pen case body, and an engagement and retention portion that maintains the engaged state of the protruding engagement portion, and has a first bottom support portion consisting of a support surface that covers at least a portion of the bottom surface of the bottom.

[0008] In addition, it is preferable that the engagement and retention mechanism uses an auxiliary plate between the fastener and the bottom surface of the pen case body, the auxiliary plate having a second bottom support portion consisting of a support surface that covers parts other than the surface covered by the first bottom support portion.

[0009] In addition, it is preferable that the engagement and retention mechanism uses a core material having a third bottom support portion consisting of a support surface covering at least a portion of the bottom surface between the interior material and exterior material that form the bottom surface of the pen case body.

[0010] It is also preferable that the adsorption body has a peripheral portion on the periphery of the adsorption portion and a pressing portion extending outward from the peripheral portion and bent, and that the bottom support portion has a straight edge extending in a direction perpendicular to the direction in which the pressing portion is located. Effect of the Invention

[0011] According to the description of claim 1, since the bottom support part can suppress deformation of the bottom of the pen case body while engaging the pen case body with the adsorbent, even if the pen case body is made of a light and easily deformed material such as cloth, the engagement between the pen case body and the adsorbent is difficult to separate, making it possible to provide a pen case in which the resin adsorbent is difficult to come off. In addition, by locating the bottom support part above the adsorbent, the weight is increased, making it possible to maintain a stable standing state.

[0012] According to claim 2, by using a fastener as the engagement and retention mechanism, the engagement and retention part of the fastener engages and retains the protruding engagement part of the adsorbent that has reached the bottom of the pen case body, realizing a stable engagement. Furthermore, by having a first bottom support part, even if the pen case body is made of a light and easily deformed material such as a cloth material, the bottom deformation is suppressed, making it difficult for the engagement between the pen case body and the adsorbent to be separated. In addition, by arranging the fastener with the bottom support part above the adsorbent, the weight is increased, making it possible to maintain a stable upright state.

[0013] According to claim 3, by using an auxiliary plate as an engagement and holding mechanism, the fastener has a second bottom support part in addition to the first bottom support part, making it possible to further suppress deformation of the bottom. Therefore, even if the pen case body is made of a light and easily deformed material such as cloth material, the engagement between the pen case body and the adsorbent is difficult to separate. In addition, by arranging the fastener and auxiliary plate with the bottom support part above the adsorbent, the weight is increased, making it possible to maintain a stable upright state.

[0014] According to claim 4, by using a core material on the bottom as an engagement and holding mechanism, in addition to the first bottom support part of the fastener and the second bottom support part of the auxiliary plate, a third bottom support part is provided, which makes it possible to further suppress deformation of the bottom. Even if a light and easily deformed material such as a cloth material is used for the pen case body, the engagement between the pen case body and the adsorbent is difficult to separate. In addition, by arranging the fastener, the auxiliary plate, and the core material with the bottom support part above the adsorbent, the weight is increased, making it possible to maintain a stable standing state.

[0015] According to claim 5, the adhesive body has a pressing portion to release the adhesive state, and by pressing the pressing portion, the adhesive portion is flipped up to release the adhesive state. Since the pressing portion side of the bottom support portion of the engagement holding mechanism has a straight edge, there is a portion on the pressing portion side of the straight edge where there is no bottom support portion and the adhesive portion can be easily flipped up, and therefore the adhesive release by the pressing portion can be stably performed.

[Figure 8] FIG. 2 is a perspective view of a pen case according to a different embodiment from that shown in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] An example of an embodiment of the present invention will be described. As shown in Fig. 1 and Fig. 2, the pen case 1 of the present invention has a pen case body 10 that stores writing implements, and an adhesive body 20 that is attached to the installation surface that is the surface to be attached. The adhesive body 20 is capable of adsorbing the installation surface of the pen case to maintain the pen case body 10 in a self-supporting state, and the pen case body 10 and the adhesive body 20 are engaged and held by engagement and holding mechanisms 30, 40, 50.

[0018] The pen case body 10 of this embodiment is a lightweight, cloth-made, approximately rectangular parallelepiped shape, and has a base 11 at the bottom and an opening 12 at the top that can be opened and closed. A fastener 13 is disposed in the opening 12, which runs from one side of the pen case body 10 through the top to the other side. Specifically, the fastener 13 has ends 13a, 13a near the base 11 on both sides of the opening 12, and the ends 13a, 13a are slightly toward the front of both sides and toward the back of the top, so that the ends 13a, 13a are inclined toward the back of the top. When the fastener 13 is opened, the opening 12 opens (see FIG. 6).

[0019] The base 11 is the lower part of the pen case body 10, which is connected to the adhesive body 20 described later and is the part that holds stationery inside. Unlike the opening 12, which is the upper part, the base 11 may use a relatively thick material to maintain the upright state, or a core material may be placed inside.

[0020] When the fastener 13 is opened, the front opening 12a on the front side (the left front side in FIG. 1) bends toward the front side, and the rear opening 12b on the rear side (the right rear side in FIG. 1) maintains an upright state. The front opening 12a bends toward the front side at the edge with the base 11, and the top surface of the pen case body 10 moves until it reaches the vicinity of the installation surface on which the adhesive body 20 is located (see FIG. 6). In this state, magnets 15, 15 are built into the front opening 12a and the front base 11a on the front side of the base 11, and the magnets 15, 15 are magnetically attached to each other, so that the front opening 12a can be folded to maintain the pen case 1 in a wide open state, and the inside of the pen case body 10 can be widely viewed.

[0021] The bottom 16 of the pen case body 10 refers to the portion having the lower surface and bottom surface of the pen case body 10, and is not limited to the inside or outside of the pen case body 10 unless otherwise specified. In this embodiment, as described later, an engagement retainer is used on the inside of the bottom 16 of the pen case body 10, but it may be used on the outside. The bottom surface refers to the bottom surface of the pen case, and the bottom 16 refers to the surrounding area including the bottom surface. The bottom surface is composed of an interior material 16a and an exterior material 16b, and has insertion holes 16c, 16c for passing protruding engagement portions 23, 23 of the adhesive body 20 described later.

[0022] Next, the adsorbent 20 that adsorbs the pen case body 10 to the installation surface will be described. The adsorbent 20 of this embodiment is mainly made of an elastomer (e.g., a resin material such as silicone resin or rubber) that has elasticity and flexibility, as shown in Figures 2 and 3, and has an adsorbent part 21 with a peripheral part 21a whose lower surface is adsorbed to the installation surface (adsorbed surface). It has a pressing part 22 that protrudes forward from the peripheral part 21a of the adsorbent part 21 and is bent to release the adsorbed state, and has two protruding engagement parts 23, 23 that protrude upward from the adsorbent part 21 (see Figure 5(b)).

[0023] The protruding engagement parts 23, 23 have protruding base parts 23b, 23b protruding upward and head parts 23a, 23a at the tips thereof, and the head parts 23a, 23a are formed in a shape extending to both sides, and the upper surface is rounded. The protruding engagement parts 23, 23 are used in an engagement holding mechanism described later, and have long holes 23c, 23c that open in the front-rear direction through which the engagement holding parts 32, 32 are inserted. The protruding engagement parts 23, 23 are not limited to this embodiment, and may have other shapes, such as a mushroom shape or a shape with no head and only a rod-shaped protruding base.

[0024] The adsorption portion 21 of the adsorption body 20 is dome-shaped and comprises a circular peripheral portion 21a, a circular central portion 21b that is recessed closer to the center than the peripheral portion 21a, and an inclined portion 21c that inclines at a gentle angle from the peripheral portion 21a to the central portion 21b.

[0025] The inclination angle of the inclined portion 21c is gently inclined at about 10 degrees or less, and when the pen case body 10 is placed on the surface to be attached, the weight of the pen case body 10 pushes out the air in the attachment portion 21, making the internal pressure lower than atmospheric pressure, generating an attachment force and enabling attachment. In addition, the peripheral portion 21a is annular, so that the attachment force is generated uniformly. Note that, although an annular shape is preferable for the peripheral portion 21a, this is not necessarily limited, and it may be an ellipse or a square shape with rounded corners.

[0026] The pressing portion 22 is composed of an extension portion 22a protruding forward from the peripheral portion 21a and a pressing surface 22b protruding upward from the extension portion 22a. By pressing the pressing surface with a fingertip or the like, the peripheral portion 21a is turned up, and air flows into the adsorbing portion 21, thereby releasing the adsorbed state between the adsorbent 20 and the adsorbed surface.

[0027] Next, the engagement and retention mechanism will be described. As shown in Figures 4 and 5, the engagement and retention mechanism engages and retains the adsorptive body 20 to the pen case body 10 by the fastener 30, the auxiliary plate 40, and the core material 50.

[0028] As shown in Fig. 4(a), fastener 30 has main body 30a (first bottom support part whose underside serves as the support surface) made of plate material having a semicircular plane, and straight side 31 formed by cutting out part of the circle when changing from a circular shape to a semicircular shape, with engaging and holding parts 32, 32 protruding from straight side 31 in a direction perpendicular to the direction (longitudinal direction) of straight side 31, so that engaging and holding parts 32, 32 and main body 30a are in the same flat plate shape. Engaging and holding parts 32, 32 are flat protruding members made of a part extending in the front-rear direction and a wide tip part, and the wide tip part is generally arrow-shaped with its width widened on both sides.

[0029] 4(b), auxiliary plate 40 has a main body 40a (a second bottom support part whose underside serves as a support surface) with a straight side 41 formed by cutting out approximately one-eighth of the lower side of a circular plate material as shown in the figure. Slotted insertion holes 42, 42 are formed on both sides of the center of the circle of auxiliary plate 40, and the auxiliary plate is a member having approximately the same thickness as fastener 30.

[0030] 4(c), the core material 50 has a main body 50a (a third bottom support part whose upper and lower surfaces are support surfaces) that has a straight side 51 formed by cutting out approximately one-eighth of the lower side of the circular plate material in the figure, just like the auxiliary plate 40. Slot-shaped insertion holes 52, 52 are formed on both sides of the center of the circle of the core material 50, and the core material is a member having approximately the same thickness as the fastener 30 and the auxiliary plate 40.

[0031] Similar to the insertion holes 42, 42 of the auxiliary plate 40 and the insertion holes 52, 52 of the core material 50, insertion holes 16c, 16c are also formed in the bottom surface of the pen case body 10 as described above (see FIG. 5(b)). In the attached state, from the bottom up, the insertion holes of the pen case body are referred to as the first insertion holes 16c, 16c, the insertion holes of the core material 50 are referred to as the second insertion holes 52, 52, and the insertion holes of the auxiliary plate 40 are referred to as the third insertion holes 42, 42.

[0032] As shown in Fig. 5(a) and (b), the protruding engagement parts 23, 23 of the adhesive body 20 are inserted into the first insertion holes 16c, 16c of the pen case body 10, and the protruding bases 23b, 23b and heads 23a, 23a of the protruding engagement parts 23, 23 are protruded into the inside of the pen case body 10. In this way, the protruding engagement parts 23, 23 of the adhesive body 20 are engaged so as to reach the bottom 16 of the pen case body 10. In this state, the fastener 30 engages and holds the adhesive body 20. In other words, when the engagement holding parts 32, 32 of the fastener 30 are inserted into the long holes 23c, 23c of the protruding engagement parts 23, 23 that have reached the inside of the pen case, the wide end parts of the engagement holding parts 32, 32 are caught in the long holes 23c, 23c, preventing them from coming off, and the engagement between the adhesive body 20 and the bottom 16 of the pen case body 10 is held.

[0033] The engagement between the protruding engagement portion 23 and the engagement holding portion 32 is difficult to come off, and in particular when the pen case body 10 is made of a relatively flexible material such as a cloth material and the adsorbent 20 is made of a resin material, a bottom support portion is provided on the bottom of the pen case body 10 on the same plane as the engagement or below it to prevent the engagement from coming off even if the bottom 16 of the pen case body 10 is deformed due to flexibility. The bottom support portion of this embodiment is the main body portion 30a of the fastener 30, the main body portion 40a of the auxiliary plate 40, and the main body portion 50a of the core material 50. Although the fastener 30 alone has a certain effect, it is preferable to use the auxiliary plate 40 in combination, and it is also preferable to add the core material 50.

[0034] When the pen case body 10 is made of a flexible material such as a cloth material, the bottom support parts 30a, 40a, and 50a can prevent the protruding engagement parts 23, 23 of the adsorbent 20 from being dislodged from the pen case body 10 due to a large deformation of the bottom, and can maintain a good engagement state between the pen case body 10 made of a flexible material such as a cloth material and the adsorbent 20 made of a resin material. In this embodiment, the lower surface of the bottom support parts 30a, the lower surface of 40a, and the upper and lower surfaces of 50a are all flat surfaces that support the bottom surface in a certain range. Although a flat surface is preferable, this is not necessarily limited, and the support surface may be made uneven to eliminate slippage. Supporting in a covering manner refers to being located within a certain range along the bottom surface and applying a certain restriction to the deformation of the bottom surface.

[0035] The bottom support portion does not need to be disposed on the entire bottom surface of the pen case body 10, but is preferably disposed on a predetermined portion. Therefore, the semicircular fastener 30's main body portion 30a (first bottom support portion) and the flat protruding retainer portion alone cover 50% of the bottom surface (40% for the first bottom support portion alone) to prevent deformation, but the auxiliary plate 40's main body portion 40a (second bottom support portion) that supplements the remaining semicircular portion is preferably provided to cover 80% of the bottom surface to prevent deformation, and it is preferable to use the core material 50 to further prevent deformation of the bottom surface. The core material 50's main body portion 50a (third bottom support portion) also supports the pen case body 10 so as to cover 90% or more of the bottom surface, but the core material 50 is inserted between the interior material 16a and the exterior material 16b on the bottom surface, so that it is less likely to shift position, and deformation of the bottom surface can be further prevented. In addition, when the fastener 30, auxiliary plate 40, and core material 50 are positioned, the weight of the pen case body 10 is raised above the adhesive body 20, making it possible for the pen case body 10 to maintain a stable upright state even when a light cloth material or the like is used.

[0036] When using the auxiliary plate 40, the protruding engagement portions 23, 23 are passed through the first insertion holes 16c, 16c of the pen case body 10, and with the protruding engagement portions 23, 23 protruding and engaging inside the pen case body 10, the auxiliary plate 40 is placed on the inner bottom surface by passing the protruding engagement portions 23, 23 through the third insertion holes 42, 42 and fastened with the fasteners 30.

[0037] In addition, when using a core material 50, the core material 50 is inserted in advance between the interior material 16a and the exterior material 16b that form the bottom surface of the pen case main body 10, and when the protruding engagement portions 23, 23 are passed through the first insertion holes 16c, 16c of the pen case main body 10, they are also passed through the second insertion holes 52, 52 of the core material.

[0038] The straight edges 31, 41, 51 of the fastener 30, auxiliary plate 40, and core material 50 all face in a direction perpendicular to the front-to-rear direction in which the pressing portion 22 is located, and the cut-out portion is located on the front side in which the pressing portion 22 is located. This ensures that the cut-out portion does not impede the lifting up of the pressing portion 22 to release the suction. The cut-out portion is about one-eighth of the front side of the bottom portion (bottom surface).

[0039] As shown in FIG. 7, a tongue 17 formed by appropriately folding and sewing a relatively rigid strip-shaped member is attached to the back side of the front opening 12a. The tongue 17 has a tongue body 17a extending from the attached base end and a tongue fold 17b formed by folding back the tip side of the tongue body 17a, and a fold edge 17c is formed by sewing the vicinity of the fold position. When the pen case 1 is used, the tongue 17 is exposed outward by folding it from the sewing position at the base end position, so that the fold edge 17c is located on the installation surface and the tongue fold 17b faces upward. In this state, it is possible to hold an electronic device D by leaning it against the tongue 17 and the fastener 13 of the front opening 12a.

[0040] Another embodiment of the pen case 1 has a lowered height of the pen case body 10, as shown in Fig. 8. By lowering the height, it is possible to reduce the width of the pen case on a desk and reduce the bulk when stored in a bag or the like. [Explanation of symbols]
