Abstract
Description
[Technical field]
[0001] The present invention relates to an article support that supports a cylindrical article so that it does not rotate about its axis. [Background technology]
[0002] When a cylindrical object is stored in a packaging box for sale, the object is usually stored in the same orientation as the packaging box, but vibrations during transportation can cause the object to rotate around its axis inside the packaging box, resulting in a misalignment between the object and the packaging box, which can cause problems. For example, if the front of the packaging box is transparent or semi-transparent so that the design or text on the cylindrical surface of the object can be seen from the outside of the storage box, the misalignment between the object and the packaging box can result in an unattractive appearance when displayed in a store or delivered to a customer.
[0003] In response to this, Patent Document 1 proposes an article support that prevents rotation around an axis of a cylindrical article stored in a packaging box (hereinafter also simply referred to as "rotation"). This article support is made of a blank sheet having a bottom plate with a width dimension narrower than the diameter of the article, and a pair of side plates connected to both ends of the bottom plate in the width direction and having an opening formed at the connection part with the bottom plate through which only a part of the bottom side of the article passes. A flexible blank sheet is used.
[0004] When an article is placed on the bottom plate and the side plate is bent upward to form a substantially U-shaped cross section, a part of the bottom side of the article protrudes from the opening of the side plate. At this time, the width of the opening at the connection position between the bottom plate and the side plate is narrower than the width of the article along the connection position, so the side plate is bent upward while bending in a curved shape from the connection position with the bottom plate. Therefore, when the article support thus bent is stored together with the article in a rectangular cylindrical packaging box having approximately the same width as the bottom plate, the side plate strongly presses against the inner wall of the packaging box due to its elastic restoring force, and the upper edge of the opening of the side plate is strongly pressed against the cylindrical surface of the article as a reaction, and the frictional resistance acting between them prevents the article from rotating.

[0005] [Patent Document 1] Patent No. 6831631 Summary of the Invention [Problem to be solved by the invention]
[0006] However, the article support proposed in Patent Document 1 above uses the flexibility and elastic restoring force of the blank sheet material to support the article so that it does not rotate around an axis, and therefore has the drawback that the type and thickness of the material from which the blank sheet is made are somewhat limited.
[0007] In other words, while using a blank sheet made of a plastic such as polypropylene provides adequate flexibility and elastic recovery force and can effectively prevent items from rotating inside the packaging box, if, for example, ordinary paperboard is used, if it is made thick enough to ensure the necessary flexibility, the elastic recovery force will be small, and if it is made too thick, it will lack flexibility and the side panels will bend during assembly, and in either case there is a risk that the function of preventing items from rotating will be insufficient.
[0008] SUMMARY OF THE PRESENT EMBODIMENTS An object of the present invention is to provide an article support that can reliably support a cylindrical article in a state in which it cannot rotate. [Means for solving the problem]
[0009] In order to solve the above problems, the article support of the present invention comprises: The blank sheet includes a bottom plate and a support piece connected to one end of the bottom plate in the width direction via a first fold line and having a support hole formed in the center of the width direction for passing a cylindrical article therethrough; a peripheral portion of the support hole of the support piece is formed by a first peripheral portion facing the first fold line, a pair of second peripheral portions respectively continuing to both circumferential ends of the first peripheral portion, and a third peripheral portion facing the first peripheral portion and respectively continuing to each of the second peripheral portions; The support piece has a first support portion that is continuous with the bottom plate via the first fold line and includes extending portions extending on both sides of the first fold line in the longitudinal direction and the first peripheral portion, a pair of second support portions that are continuous with each extending portion of the first support portion via a second fold line and include the second peripheral portion, and a third support portion that is continuous with each second support portion via a third fold line and includes the third peripheral portion, the second fold line and the third fold line respectively starting from the boundary between the first peripheral portion and the second peripheral portion and the boundary between the second peripheral portion and the third peripheral portion and extending in a direction approaching each other, In the state of the blank sheet, the width direction length of the support piece is formed longer than the width direction length of the bottom plate, With the object passed through the support hole of the support piece, one widthwise end of the third support part of the support piece is rotatably connected to the other widthwise end of the bottom plate, so that the first support part and the third support part of the support piece rise up from the bottom plate and the distance between the second peripheral parts of the pair of second support parts becomes narrower in a plan view than in the blank sheet state, thereby clamping and supporting the object between the two second peripheral parts (configuration 1).
[0010] When the article support body of configuration 1 described above is assembled with a cylindrical article passed through the support hole of the support piece, the distance between the second peripheral portions of the pair of second support parts becomes narrower in a plan view than in the blank sheet state, and the article is clamped between both second peripheral portions. Therefore, even if the material forming the blank sheet does not have high flexibility or a large elastic restoring force, as long as the material has a certain degree of rigidity, the article can be reliably supported in an unrotatable state.
[0011] In the above configuration 1, it is preferable that at least the circumferential center of each of the second peripheral edges of the support pieces is formed in an arc shape (configuration 2). In this way, when both second peripheral edges of the support pieces clamp an article, the contact length between each of the second peripheral edges and the article becomes longer, and rotation of the article can be more reliably prevented.
[0012] Furthermore, in the above configurations 1 or 2, if at least the circumferential central portions of the first and third peripheral portions of the support piece are formed into an arc shape having an inner diameter equal to the outer diameter of the article (configuration 3), the article support body will not only clamp the article in the longitudinal direction between the two second peripheral portions, but also clamp the article in the width direction between the first and third peripheral portions, thereby preventing the article from tilting or shifting in the width direction and supporting the article more stably. Effect of the Invention
[0013] As described above, the article support of the present invention is designed so that when a cylindrical article is passed through the support hole of the support piece and assembled, the article is clamped between the second peripheral portions of a pair of second support parts formed on both sides of the support hole.Therefore, even if the material forming the blank sheet used as the base does not have high flexibility or a large elastic restoring force, the article can be reliably supported in an unrotatable state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows a packaging box 2 in which an article support 1 according to the embodiment is stored together with an article A to be supported. The article A is a cylindrical bottle with a small diameter opening closed with a cap. As shown in Figs. 1 and 2, the packaging box 2 is formed from a single blank paper sheet, and includes a front wall 3 and a rear wall 4 forming a peripheral wall having a cross section shaped like a convex lens when assembled, an upper lid 5 closing an opening at the upper end of the peripheral wall, a bottom lid 6 closing an opening at the lower end of the peripheral wall, an upper holding piece 7 holding the cap portion of the article A, and a bottom holding piece 8 holding the article A in a state where it is lifted from the bottom lid 6.
[0016] As shown in Fig. 2, the blank sheet from which the packaging box 2 is made has a rear wall 4 on one side of a front wall 3, an attachment plate 9 on the other side, a top cover 5 at the top end, and a bottom cover 6 at the bottom end, and has an upper holding piece 7 attached to the top end of the rear wall 4 and a bottom holding piece 8 attached to the bottom end. The attachment plate 9 is placed on the inner surface of the rear wall 4 during assembly and is fixed with an adhesive. A rectangular window 3a is provided in the front wall 3 so that the design or characters on the cylindrical surface of the item A stored in the packaging box 2 can be seen from the outside of the packaging box 2. The top end of the rear wall 4 is located lower than the top end of the front wall 3.
[0017] The top cover 5 is made up of a rectangular connection part 5a continuing to the upper end of the front wall 3, a convex lens-shaped top cover part 5b continuing to the upper end of the connection part 5a, and a tongue-shaped top cover piece 5c continuing to the upper end of the top cover part 5b. The bottom cover 6 is made up of a convex lens-shaped bottom cover part 6a continuing to the lower end of the front wall 3, and a tongue-shaped bottom cover piece 6b continuing to the lower end of the bottom cover part 6a.
[0018] An upper insertion portion 10 is formed along the fold line r between the rear wall 4 and the upper holding piece 7, into which the upper cover insert piece 5c is inserted during assembly, and an upper insertion portion 11 is formed along the fold line r between the rear wall 4 and the bottom holding piece 8, into which the bottom cover insert piece 6b is inserted during assembly. Note that the fold lines r in Fig. 2 are shown with solid lines for those that are mountain folds and dashed lines for those that are valley folds.
[0019] The upper holding piece 7 has a holding hole 7a formed in the center, the upper half of which is semicircular and the lower half of which is rectangular, through which the cap portion of the article A is passed. The bottom holding piece 8 is composed of a trapezoidal first inclined portion 8a continuing to the lower end of the rear wall 4 and a trapezoidal second inclined portion 8b continuing to the lower end of the first inclined portion 8a, and is folded along the fold line r so that the two inclined portions 8a, 8b are inclined in opposite directions to each other with respect to the bottom cover 6 during assembly.
[0020] When assembling this packaging box 2, first, the front wall 3 of the blank sheet is folded back at crease line r so as to overlap the front surface of the rear wall 4, and then the attachment plate 9 is folded between the front wall 3 and the rear wall 4 at crease line r. After that, adhesive is applied to the surface of the attachment plate 9 facing the rear wall 4, and the attachment plate 9 is adhesively fixed to the front surface of the rear wall 4 (the inner surface when assembled).
[0021] Next, the front wall 3 and the rear wall 4 are bent in the width direction to form a peripheral wall whose cross-sectional shape is a convex lens, and the first inclined portion 8a and the second inclined portion 8b of the bottom holding piece 8 are folded so that the fold line r between them becomes the apex of a mountain shape, and the peripheral wall is inserted inside the peripheral wall.
[0022] Then, the bottom lid portion 6a of the bottom lid 6 is folded along the crease line r and fitted inside the peripheral wall, and the bottom lid insert piece 6b is inserted into the lower insertion portion 11 between the rear wall 4 and the bottom holding piece 8 and folded to close the opening at the lower end of the peripheral wall. This results in an intermediate assembly state in which the article support 1 supporting the article A can be received, as described below. In this intermediate assembly state, the article A and the article support 1 are inserted from the opening at the upper end of the peripheral wall, and the first inclined portion 8a and the second inclined portion 8b of the bottom holding piece 8 hold the article A together with the article support 1 in a state of being lifted up from the bottom lid 6 (see Figures 5 and 6). Thereafter, the upper holding piece 7 is folded along the crease line r toward the inside of the peripheral wall, and the cap portion of the article A is passed through the holding hole 7a, so that the cap portion of the article A is held by the peripheral portion of the holding hole 7a.
[0023] Finally, the connection portion 5a of the top cover 5 is folded along the crease line r so as to follow the rear surface of the front wall 3, and then the top cover portion 5b is folded along the crease line r to fit inside the peripheral wall, and the top cover insert piece 5c is inserted into the upper insertion portion 10 between the rear wall 4 and the upper holding piece 7 and folded to close the opening at the upper end of the peripheral wall. This completes the assembly of the packaging box 2 with the article A stored together with the article support 1.
[0024] Next, the structure and operation of the article support 1 of the embodiment that is stored in the packaging box 2 together with the article A as described above will be described.
[0025] The article support 1 is formed from one paper blank sheet, similar to the packaging box 2. As shown in Fig. 3, the blank sheet from which the article support 1 is made has a bottom plate 12 and a support piece 13 that is connected to one end of the bottom plate 12 in the width direction (the vertical direction in Fig. 3) via a first fold line r1 and has a substantially circular support hole 13a formed in the center in the width direction for passing the article A through. The width length of the support piece 13 is formed to be longer than the width length of the bottom plate 12.
[0026] The peripheral portion of the support hole 13a of the support piece 13 is formed by a first peripheral portion 14a facing the first fold line r1, a pair of second peripheral portions 14b each continuing to both circumferential ends of the first peripheral portion 14a, and a third peripheral portion 14c facing the first peripheral portion 14a and each continuing to each of the second peripheral portions 14b.
[0027] Here, the first peripheral edge portion 14a and the third peripheral edge portion 14c are each formed in an arc shape with an inner diameter equal to the outer diameter of the article A at the circumferential center portion. Moreover, each second peripheral edge portion 14b is formed in an arc shape with an inner diameter slightly larger than the outer diameter of the article A over almost the entirety thereof except for both circumferential ends.
[0028] The support piece 13 comprises a first support portion 15 that is continuous with the bottom plate 12 via a first fold line r1 and includes an extending portion 15a and a first peripheral portion 14a extending on both longitudinal sides of the first fold line r1, a pair of second support portions 16 that are continuous with each of the extending portions 15a of the first support portion 15 via a second fold line r2 and include a second peripheral portion 14b, and a third support portion 17 that is continuous with each of the second support portions 16 via a third fold line r3 and includes an extending portion 17a and a third peripheral portion 15c.
[0029] The second fold line r2 and the third fold line r3 extend from the boundary between the first peripheral portion 14a and the second peripheral portion 14b and the boundary between the second peripheral portion 14b and the third peripheral portion 14c, respectively, and intersect with each other. Accordingly, the first support portion 15 and the third support portion 17 are formed in a generally dogleg shape, and each second support portion 16 is formed in a generally triangular shape. The first support portion 15 and the third support portion 17 are symmetrical with respect to the widthwise center line.
[0030] An insertion piece 18 is connected to the other widthwise end of the bottom plate 12 via a fold line r, and a flap piece 19 is connected to one widthwise end of the support piece 13, excluding the extended portion 17a of the third support portion 17, via a fold line r. A notched insertion portion 20 into which the insertion piece 18 is inserted during assembly is formed midway along the fold line r between the third support portion 17 and the flap piece 19.
[0031] When assembling this article support 1, first, the lower end of the article A is passed through the support hole 13a of the blank sheet, and the bottom plate 12 is folded at the first fold line r1 to face the bottom surface of the article A. Then, the flap piece 19 is folded at the fold line r to be inserted between the bottom plate 12 and the bottom surface of the article A, and then the insertion piece 18 is folded at the fold line r to be inserted into the insertion part 20 between the third support part 17 and the flap piece 19, thereby rotatably connecting one end of the width direction of the third support part 17 of the support piece 13 to the other end of the width direction of the bottom plate 12, and the assembly is completed in a state in which the article A is supported (as shown in FIG. 4).
[0032] Here, since the support piece 13 is formed such that its widthwise length is longer than the bottom plate 12 in the blank sheet state, when assembled as described above, it bends at the second fold line r2 and the third fold line r3 as shown in Fig. 4, and the first support portion 15 and the third support portion 17 rise from the bottom plate 12 while bending so that the extending portions 15a, 17a on both sides in the longitudinal direction approach each other. As a result, the distance between the second peripheral portions 14b of the pair of second support portions 16 naturally becomes narrower in plan view than in the blank sheet state, and both second peripheral portions 14b sandwich and support the article A (see Fig. 5).
[0033] At the same time, both second support portions 16 are subjected to a force in a direction moving them away from item A, so that the entire support piece 13 is expanded in the longitudinal direction more than when assembled alone (without item A), and as a result, the first peripheral portion 14a and the third peripheral portion 14c attempt to shrink in the width direction, clamping item A.
[0034] In other words, when this article support body 1 is assembled with article A passing through support hole 13a, it clamps article A in both the longitudinal and widthwise directions (see the thick arrows in Figures 5 and 6), and the frictional resistance acting between the peripheral portion (first to third peripheral portions 14a, 14b, 14c) of support hole 13a and the outer circumferential surface of article A ensures that article A cannot rotate.
[0035] The article support 1 assembled together with the article A as described above has a convex lens shape in plan view that fits inside the peripheral wall of the packaging box 2 in the assembled state.
[0036] Therefore, as described above, the article support 1 assembled together with the article A is inserted through the opening at the upper end of the peripheral wall of the packaging box 2 in an intermediate assembly state, its bottom plate 12 is placed on the bottom holding piece 8 of the packaging box 2, the upper holding piece 7 holds the cap portion of the article A, and the upper lid 5 is then used to close the opening at the upper end of the peripheral wall, resulting in the completed assembly of the packaging box 2 shown in Figure 1.
[0037] In this assembled state, as shown in Figures 5 and 6, the article support 1 supporting the article A in an unrotatable state is fitted unrotatably into the peripheral wall of the packaging box 2, so that even if subjected to vibrations during transportation, the article A and the article support 1 will not rotate within the packaging box 2, and the desired part of the design or letters on the cylindrical surface of the article A can be maintained visible from the outside of the packaging box 2 through the window 3a in the front wall 3. Therefore, the article can be displayed in a store or delivered to a customer in a constantly good-looking state.
[0038] Moreover, unlike the conventional article support 1 described above, the blank sheet used as the material does not necessarily have to be made of a material such as plastic that has high flexibility and large elastic recovery force, and so, as in the embodiment, the material is a paper blank sheet that has a certain degree of rigidity, making it a product that places less strain on the environment.
[0039] In addition, since this article support 1 can support article A by assembling it together with article A, it has the advantage that, for example, a design or text can be printed on the surface and the article can be displayed in a store supporting article A by itself without being stored in a packaging box 2.
[0040] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is defined by the claims, not by the above meaning, and is intended to include all modifications within the scope and meaning equivalent to the claims.
[0041] For example, the connection between the other widthwise end of the bottom plate of the article support and one widthwise end of the third support part of the support piece is not limited to a configuration in which an insert piece connected to the bottom plate is inserted into the insert part between the third support part of the support piece and the flap piece as in the embodiment, but may be a configuration in which the two can be rotatably connected.
[0042] In addition, the blank sheet that serves as the material for the article support is desirably made of paper as in the embodiment, taking into consideration the burden on the environment, but it can also be made of plastic depending on the application, such as when the packaging box itself is made of transparent plastic so that the entire article can be seen from the outside.
