Description

Technical Field

[0001] The present disclosure relates to a clamp for fixing a lid (flip) of a box in an open state. Background Art

[0002] There is a jig (clamp) for fixing the flap, which improves operability by fixing the lid (flip) of the box in an open state to disassemble the box and remove items from the inside.

[0003] Conventionally, a clamp (clamping member) such as that proposed in Patent Document 1 is known.

[0004] The clamp for the cover of a box disclosed in patent document 1 is configured to form a triangle with the corner of the box by inserting at least two legs on the outside of the clamp into the outside of the box and inserting at least one leg in the middle of the clamp into the inside of the box at the corner of the box to temporarily fix the cover of the box.

[0008] Technical problems to be solved by the present disclosure

[0009] However, the clip for the cover of a box disclosed in Patent Document 1 has the problems described below.

[0010] The clip for a box cover disclosed in Patent Document 1 includes three legs inserted into each of four corners of a box body.

[0011] Therefore, in order to attach a clamp for the lid to a corner of the box body, a worker should align the three legs of the clamp for the lid (flip) connected to the two side panels adjacent to the corner and insert the clamp into the intended corner while keeping the opened lid (flip) superimposed on the side panels to prevent the lid (flip) from returning to the closed direction. Therefore, the work of attaching the clamp for the lid is complicated, and it is difficult for a single worker to smoothly and quickly attach the clamp to the box body, making it difficult to use.

[0012] The present disclosure has been made to solve the above problems in the conventional technology. An object of the present disclosure is to provide a clamp for fixing a flap for superimposing and fixing a flap of a box on a side panel of the box, which is easily, conveniently and highly practically attached to the box.

[0013] Solutions to technical problems

[0014] In order to achieve the above object, according to the first aspect of the present disclosure,

[0015] (1) A clamp for fixing the flap, which is used to fold the flap of the box outward and overlap and fix the flap on the side panel of the box, and the clamp includes:

[0016] a plate-shaped body; and

[0017] An incision made by removing a portion of the body,

[0018] in,

[0019] The cutout has an opening width to allow the side panel and the flap overlying the side panel to be inserted into the cutout.

[0020] According to the first aspect of the present disclosure, the clamp for fixing the flap can be attached (fixed) to the box by simply inserting the connecting portion (folded portion) between the flap and the side panel from the open end of the cutout while the flap of the box is superimposed on the side panel of the box. Therefore, according to the first aspect of the present disclosure, a convenient and highly practical clamp for fixing the flap can be provided, which can be attached to the box (i.e., fix the flap) smoothly and quickly.

[0021] In the clamp for fixing a flip cover according to the first aspect of the present disclosure, the second to seventh aspects of the present disclosure described below are also preferred.

[0022] According to a second aspect of the present disclosure, in the jig for fixing the flip cover according to the first aspect of the present disclosure, the closed end of the cutout has a circular shape.

[0023] According to the second aspect of the present disclosure, even when a force acts in a direction to restore the flap to move away from the side panel while the flap superimposed on the side panel of the box is fixed by the jig for fixing the flap, the force acting in the tensile direction at the closed end of the cutout is distributed to be less likely to cause breakage, rather than being concentrated in one location, compared to, for example, a case where the closed end of the cutout is a polygonal shape, etc. Therefore, tearing of the main body can be preferably avoided.

[0024] According to a third aspect of the present disclosure, in the jig for fixing the flip cover according to the first aspect of the present disclosure, the cutout has a tapered shape that becomes narrower from the closed end toward the open end.

[0025] According to the third aspect of the present disclosure, the clamp for fixing the flip cover can prevent the flip cover superimposed on the side panel of the box from opening away from the side panel, and can also prevent the clamp for fixing the flip cover itself from being accidentally released as the flip cover opens, thereby ensuring that the flip cover remains fixed.

[0026] According to a fourth aspect of the present disclosure, in the jig for fixing the flip cover according to the first aspect of the present disclosure, at least a portion of a side of the body opposite to the open end of the cutout extends flat in a direction perpendicular to an extending direction of the cutout.

[0027] According to a fourth aspect of the present disclosure, at least a portion of one side of the body opposite to the open end of the cutout extends flat in a direction perpendicular to the extending direction of the cutout, so that the boxes on the bottom side and the boxes on the top side are arranged and stacked almost vertically.

[0028] According to a fifth aspect of the present disclosure, the jig for fixing the flip cover according to the first aspect of the present disclosure further includes a protrusion located at a position on a side of the main body opposite to the open end of the cutout.

[0029] According to a fifth aspect of the present disclosure, another box can be stacked on top of the jig securing the box's flap. In this case, the protrusion stably supports the box by effectively (and reliably) preventing the other box on the upper side from shifting or falling. Thus, the jig securing the flap provides a highly stable and secure stack of multiple boxes, preventing the upper box from falling, damaging the box and its contents (items, etc.), and delaying work.

[0030] According to a sixth aspect of the present disclosure, in the jig for fixing the flip cover according to any one of the first to fifth aspects of the present disclosure, the main body is made of at least one material of paper, wood, resin, metal, and ceramics.

[0031] The body may be made from one or more of these materials.

[0032] The second aspect of the present disclosure is particularly effective when the main body is made of paper. In other words, according to the second aspect of the present disclosure, even if the main body is made of paper, high strength can be achieved to prevent damage. Therefore, a practical clamp for securing the flap can be provided, which has the ability to effectively secure the flap.

[0033] The entire clamp for securing the paper flap can remain attached without having to be removed from the carton (such as a cardboard box) for processing (such as disposal or recycling). Therefore, after the items are removed from the box interior, the box can smoothly and efficiently undergo automated processing, such as disposal or recycling. Furthermore, the need for manual removal work is eliminated, thereby reducing labor and improving efficiency.

[0034] According to a seventh aspect of the present disclosure, in the clamp for fixing the flip cover according to the sixth aspect of the present disclosure, the main body is made of cardboard, and

[0035] The width direction of the layer in the body is the extending direction of the cutout.

[0036] According to the seventh aspect of the present disclosure, the cardboard has stronger compression resistance in the layer (paper width) direction than in the flow direction. When boxes are stacked on top of each other with the flap secured by the clamp for securing the flap, the load-bearing capacity of the clamp for securing the flap can be increased, making it less likely to be damaged.

[0037] Technical Effects

[0038] The present disclosure may provide a clamp for fixing a flap of a case by overlapping and fixing the flap to a side panel of the case, which is easily, conveniently, and highly practically attached to the case. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The present disclosure will be described in more detail below using suitable examples, which are however only examples that embody the present disclosure and are not intended to be limiting.

[0047] Configuration of the clamp for securing the flap

[0048] The following references Figures 1 to 7 The configuration of a clamp for fixing a flip cover in one embodiment of the present disclosure is described.

[0049] Figure 1A front view of a clamp for securing a flip cover according to one embodiment of the present disclosure is shown. Figure 2 A perspective view showing the arrangement of the clamp for securing the flap. Figure 3 A plan view showing the arrangement of the clamp for securing the flap. Figure 4 A partial enlarged view of a clamp for securing a flap is shown in use, securing the flap of a box to another box placed on top. Figure 5 A perspective view of a clamp in use for securing a flap attached to a box is shown. Figure 6 A plan view of the clamp for securing the flap is shown in use. Figure 7 Shown is a perspective view of the clamps used to secure the flaps when the boxes are stacked.

[0050] like Figures 1 to 4 As shown, the clamp for fixing the flap 1 is used to fold the flap 102 of the box 100 outward and overlap and fix the flap 102 on the side panel 101 of the box 100 .

[0051] The box 100 using the clamp for fixing the flap is, for example, a well-known rectangular cardboard box, also known as Figure 5 and Figure 6 The flaps 102 are hingedly and rotatably connected to the upper and lower ends of each of the four side panels 101. The box 100 serves as a hollow box-like package with the four lower flaps closed and the four upper flaps 102 opened and closed as lids.

[0052] The four upper flaps 102 of the box 100 are opened, and work such as inserting or removing items into or from the box 100 is performed.

[0053] In other words, the clamp for fixing the flip cover 1 of this embodiment is suitable for superimposing and fixing the four upper flip covers 102 of the box 100 on the side panels 101 of the box 100 so as to prevent the opened flip covers 102 from returning in the closing direction, thereby facilitating the work of inserting or removing articles into or from the box 100 while the flip covers 102 are opened.

[0054] The clamp for fixing the flip cover 1 has a main body 2 and a cutout 3. The main body 2 is formed in a plate shape. The cutout 3 is formed by cutting away a portion of the plate-shaped main body 2. As will be described later, a protrusion 4 is integrally formed on the main body 2.

[0055] like Figure 1 and Figure 2 As shown, the cutout 3 is formed by cutting off a portion of the main body 2. In this embodiment, for example, the approximate center of one side of the main body 2 ( Figure 1From the open end 3a, the main body 2 is cut with a predetermined opening width to form a long opening on the inner side of the main body 2 to form a closed end 3b at the approximate center of the main body 2.

[0056] In other words, the cutout 3 is formed by a cutout opening so that the upper portion of the main body 2 is a connecting base 2c, while the lower side is bifurcated into two arms 2a arranged side by side. The schematic outline of the main body 2 with the cutout 3 is an inverted approximately U-shape with an opening facing downward. Then, the main body 2 is attached and engaged with the side panel 101 of the box 100 and the flip cover 102 superimposed on the side panel 101, while the flip cover 102 is fixed (see FIG. Figure 4 ).

[0057] The cutout 3 is formed with a specified length from the open end 3a to the closed end 3b so that the clamp for fixing the flip cover 1 can be fully engaged with the side panel 101 and the flip cover 102 of the box 100, so that the flip cover 102 superimposed on the side panel 101 can be inserted with a certain amount of receiving length. The cutout 3 is set to 32 mm in the cutout direction from the open end 3a (i.e., the open position on the same line as the lower side of the main body 2) to the farthest end of the closed end 3b, for example.

[0058] The longer the cutout 3 is in the cutout direction, the better the securing effect on the flap 102. However, an excessively long length will reduce the operability of attaching the flap 102. Therefore, considering operability, the length of the cutout 3 is preferably 20 mm to 40 mm, more preferably 30 mm to 35 mm. Of course, a longer cutout 3 requires a correspondingly larger main body 2 of the fixture used to secure the flap 1. Therefore, in order to conserve resources for the material of the main body 2 and reduce costs, a shorter (shallower) cutout 3, having a length (depth) sufficient to secure the flap 102 in the direction of superposition on the side panel 101, is preferred.

[0059] The opening width of the cutout 3 is long enough to insert the side panel 101 of the box 100 and the flap 102 superimposed on the side panel 101 into the cutout 3. In other words, the opening width of the cutout 3 is slightly larger than the thickness of the side panel 101 of the box 100 plus the thickness of the flap 102.

[0060] According to the above configuration of the clamp for fixing the flip cover 1, while the flip cover 102 of the box 100 is superimposed on the side panel 101 of the box 100, the clamp for fixing the flip cover 1 can be attached (fixed) to the box 100 by simply inserting it from the open end 3a of the cutout 3 into the connection portion between the flip cover 102 and the side panel 101 (the folded portion of the flip cover 102 and the side panel 101). Therefore, a convenient and highly practical clamp for fixing the flip cover 1 can be provided, which can be smoothly and quickly attached to the box 100 (i.e., fix the flip cover 102).

[0061] A portion of the closed end 3b of the cutout 3 is formed into an arc-shaped circle to form an arc. The shape of the circular closed end 3b is formed, for example, by an arc having a radius of 3 mm to 10 mm, preferably 5 mm. The circumferential angle of the arc portion forming the circle is, for example, 60° to 120°, preferably 75° to 90°.

[0062] According to this configuration, even when the flap 102 superimposed on the side panel 101 of the box 100 is fixed using the jig for fixing the flap 102, a force acts in a direction to restore the flap 102 to move away from the side panel 101. The force in the tensile direction acting at the closed end 3b of the cutout 3 is distributed so as to be less likely to cause breakage, rather than being concentrated in one position, compared to, for example, a case where the shape of the closed end 3b of the cutout 3 is a polygon or the like. Therefore, the main body 2 can be well prevented from being torn.

[0063] In addition, the slit 3 is formed into a tapered shape that gradually narrows from the closed end 3b side to the open end 3a side. In other words, the slit 3 has a V-shaped taper toward the lower side of the open end 3a, and the diameter portion of the circular arc portion of the rounded portion of the closed end 3b has the maximum opening width.

[0064] According to this configuration, the clamp for fixing the flip cover 1 can prevent the flip cover 102 superimposed on the side panel 101 of the box 100 from opening away from the side panel 101, and can prevent the clamp for fixing the flip cover 1 from being accidentally released when the flip cover 102 is opened, thereby ensuring that the flip cover 102 remains fixed.

[0065] In this embodiment, both ends of the open end 3a of the cutout 3 are chamfered and have a widened inverted taper 3d that is different from the above-mentioned tapered shape. As described above, the cutout 3 of the clamp for fixing the flip cover 1 has an inverted taper 3d that widens toward the open end 3a. This means that when the flip cover 102 of the box 100 is superimposed on the side panel 101, the connecting portion (folded portion) between the flip cover 102 and the side panel 101 is easily inserted from the open end 3a of the cutout 3 and is guided to the center of the cutout 3 along the inverted taper 3d. Therefore, the operability of attaching the clamp for fixing the flip cover 1 is improved. As a matter of course, the tapered portion 3c can be extended and connected to the lower side without the opposite tapered portion 3d.

[0066] like Figure 4 and Figure 5 As shown, the main body 2 is on the side opposite to the opening end 3a of the cutout 3 ( Figure 1 The upper side of the main body 2 has a loading end 2b on which another box 100 can be placed. In addition, a protrusion 4 described later adjacent to the loading end 2b of the main body 2 is integrally provided with the main body 2.

[0067] The protrusion 4 is provided at a position on the side of the main body 2 opposite the opening end 3a of the cutout 3. The protrusion 4 is provided on the upper side of the main body 2 opposite the opening end 3a of the cutout 3, closer to the left (or right) side, and protrudes upward by a predetermined height. In other words, the protrusion 4 is located closer to the right or left (only one side) relative to the opening end 3a of the cutout 3 in the main body 2. The protrusion 4 is integrally formed with the main body 2, protruding from the side end relative to the opening end 3d of the cutout 3. At the side end on the side where the protrusion 4 is not provided, the cutout 3 extends flat in a direction perpendicular to the extension direction of the cutout 3, without any bumps or depressions (protrusions). This forms the loading end 2b. Therefore, the overall schematic outline of the clamp for securing the flip cover 1 is a roughly H-shaped clamp with the opening facing downward, in which the main body 2, including the protrusion 4 and the cutout 3, is formed. When the jig for fixing the flap 1 is attached to the box 100 to fix the flap 102 of the box 100 , the protrusion 4 is placed outside the box 100 .

[0068] The protrusion 4 has a protrusion width of, for example, 15 mm from the upper end side of the main body 2 .

[0069] For example, the protrusion 4 is formed in a substantially trapezoidal (or triangular) shape and protrudes above the loading end 2b on the upper side of the main body 2, wherein the base side is connected to the upper end of the main body 2. Specifically, one side of the protrusion 4 ( Figure 1 The left side of the projection 4 forms a straight line shared with the vertical side of the main body 2. On the right side of the projection 4, a slope 4a is formed, which is inclined downward toward the loading end 2b of the main body 2. The slope 4a of the projection 4 is set to a 45-degree slope, for example, with the loading end 2b being 0 degrees. The protrusion position of the projection 4 on the upper end side of the main body 2 (that is, the connection position between the slope 4a of the projection 4 and the loading end 2b of the main body 2) is set at a substantially central position on the upper end side of the main body 2, so that the connection position is almost directly above the open end 3b of the cutout 3.

[0070] According to this configuration, a plurality of boxes 100 can be stacked and stored using the clamp for fixing the flap 1 attached to the box 100. In this case, the protrusion 4 can stably load the box 100 by well (reliably) preventing another box on the upper side from shifting or falling. Therefore, the clamp for fixing the flap 1 makes the plurality of boxes 100 stacked in multiple layers highly stable and secure, thereby preventing the upper box 100 from falling, damaging the box 100 and its contents (articles, etc.) and delaying work.

[0071] Furthermore, when the box 100 is loaded onto the jig for fixing the flip cover 1, the provision of the inclined surface 4a on the right side of the protrusion 4, which is inclined downward toward the loading end 2b of the main body 2, makes it easier to position the box 100 than providing the right side of the protrusion 4 perpendicular to the loading end 2b. This can improve the operability, reliability, and safety of the stacking work.

[0072] In addition, since the protruding position of the protrusion 4 (i.e., the connection position between the inclined surface 4a of the protrusion 4 and the loading end 2b of the main body 2) is set directly above the position of the cutout 3, the lower box 100 and the upper box 100 can be stacked so that they are arranged almost vertically when the boxes 100 are stacked.

[0073] How to use the clamp to secure the flap

[0074] Next, refer to Figures 4 to 7 The use of the clamp for fixing the flip cover in this embodiment is described.

[0075] In order to use the clamp for fixing the flip cover 1 in this embodiment, each of the four upper flip covers 102 of the box 100 is fixed by one clamp for fixing the flip cover 1, such as Figures 4 to 6 As shown. To attach the clamp for fixing the flip cover 1, while the flip cover 102 of the box 100 is superimposed on the side panel 101 of the box 100, the cutout 3 of the main body 2 is aligned with the connection portion between the flip cover 102 and the side panel 101 (the folded portion between the flip cover 102 and the side panel 101). Then, the connection portion (folded portion) between the flip cover 102 and the side panel 101 is inserted from the open end 3a of the cutout 3 until the connection portion between the flip cover 102 and the side panel 101 contacts the closed end 3b or (farthest) approaches the closed end 3b. At this time, as shown Figure 5 and Figure 6 As shown, the loading end 2b of the main body 2 is placed toward the interior of the box 100 so that the protrusion 4 side is located outside the box 100. Figure 5 and Figure 6 As shown, the four clamps for fixing the flip cover 1 are arranged so that the corresponding panels of the main body 2 are in an upright position. Figure 6 As shown in the plan view in FIG, the plate surface of the main body 2 of the clamp for securing the flip cover 1 is oriented at 90 degrees to the plate surface of the adjacent clamp for securing the flip cover 1. In other words, the side surfaces of the opposing side panels 101 of the box 100 are brought together, and the plate surfaces of the main body 2 of the clamp for securing the flip cover 1 extend in approximately the same direction, but their positions are point-symmetrical with respect to the center of the box 100. In this way, each of the clamps for securing the flip cover 1 is attached to secure, for example, a position closer to the end of one of the flip cover 102 and side panels 101, that is, a position closer to a corner of the box 100.

[0076] like Figure 4 and Figure 7As shown, as described above, in order to stack a plurality of boxes 100 in layers while the jig for fixing the flip cover 1 is attached to the box 100, the upper box 100 is placed from above the jig for fixing the flip cover 1. In this case, the upper loading end 2b and the protrusion 4 on the upper end side of the main body 2 of each of the four jigs for fixing the flip cover 1 cooperate with each other to stably place the box 100 on the upper end side.

[0077] The size of each component of the above-described jig for fixing the flip cover 1 is an example and varies according to the size of the box 100 .

[0078] Main material

[0079] In the clamp for fixing the flip cover of this embodiment, the main body 2 is preferably made of at least one material selected from the group consisting of paper, wood, resin, metal, and ceramics.

[0080] The main body 2 may be made of one or more of these materials.

[0081] For example, plywood and cedar wood for whole pieces (composite panels) can be used as lumber.

[0082] For example, polypropylene resin can be used as the resin.

[0083] For example, aluminum can be used as the metal.

[0084] These materials vary depending on the usage environment of the box 100 and the like.

[0085] The configuration in which the closed end 3b of the cutout 3 is rounded is particularly effective when the main body 2 is made of paper. In other words, this configuration achieves high strength to prevent damage even when the main body is made of paper. Therefore, a practical fixture for securing the flip cover 102 that is highly capable of securing the flip cover 102 can be provided.

[0086] The entire clamp for securing the flap 1 made of paper can remain attached without having to be removed from the carton (such as a cardboard box) for processing (such as disposal or recycling). Therefore, after the items are removed from the interior of the box 100, processing such as disposal and recycling can be smoothly and efficiently automated, which can also reduce labor and be more efficient by eliminating the need for manual removal work.

[0087] like Figure 2 and Figure 3 As shown, the main body 2 is made of, for example, double-layer reinforced cardboard (AA groove) formed into a flat, spread board with a constant overall thickness. The main body 2, excluding the protrusion 4, has an approximately square shape with external dimensions of, for example, 50 mm×50 mm and has a thickness of, for example, 10 mm.

[0088] exist Figure 2 and Figure 3 In the embodiment, the flow direction W of the main body 2 (where the corrugations of the paperboard alternately repeat the unevenness of its wave shape) is the horizontal direction, and the width direction L or the paper width direction along the layer perpendicular to the flow direction W is the vertical direction. Figure 2 , a plurality of long vertical lines drawn in dashed lines conceptually represent layers of paperboard.

[0089] In other words, in Figure 2 and Figure 3 In FIG. 2 , the width direction L of the layer of the main body 2 is the direction in which the cutouts 3 extend.

[0090] According to this configuration, the paperboard is more resistant to compression in the layer (paper width) direction L than in the flow direction W. When the box 100 is stacked on top of the box 100 having the flap 102 , which is secured by the clamp for securing the flap 1 , the load-bearing capacity of the clamp for securing the flap 1 can be increased, making it less likely to be damaged.
