Description

[Technical field]

[0001] This invention relates to improvements in packaging materials. [Background technology]

[0002] Patent Document 1 shows a packaging material that consists of a board and a film attached to one side of the board. The packaged item is positioned between the board and the film, and then part of the board is folded to tightly adhere the film to the packaged item, so that the film and board hold the packaged item without it becoming loose.

[0003] However, such packaging materials have problems when holding multiple packaged objects of different sizes, thicknesses, shapes, etc. This is because, with such packaging materials, the distance between the film and the board is determined by, for example, the thickest packaged object among the multiple packaged objects, and there are cases in which the film and the board cannot be tightly attached to a packaged object that is thinner than this.

[0016] A typical embodiment of the present invention will be described below with reference to Figures 1 to 19. A packaging material 1 according to this embodiment can hold a plurality of packaged items M of different sizes, thicknesses, shapes, etc. together without any looseness.

[0017] Here, Figures 1 to 8 show a first example of packaging material 1, Figures 9 to 18 show a second example in which part of the configuration of the first example is modified, and Figure 19 shows a third example in which the central part of the first packaging material 2 is glued to the seat portion 3a of the second packaging material 3 of the second example, and the fastening member is omitted.

[0018] (First Example) The packaging material 1 according to the first example is composed of a first packaging material 2, a second packaging material 3, and a fastening member 4.

[0019] The first packaging material 2 has a planar, flexible configuration that allows for the creation of a knot 2b that keeps the packaged item M wrapped. In the illustrated example, the first packaging material 2 has a rectangular outline and four corners 2a. The first packaging material 2 can typically be made of nonwoven fabric, woven fabric, knitted fabric, resin sheet, or the like.

[0020] The second packaging material 3 is a planar, rigid structure including a seating surface 3a for the packaged item M and side surfaces 3c connected to the seating surface 3a via lines 3b on both sides of the seating surface 3a so that the side surfaces can be raised. As the second packaging material 3, a corrugated cardboard sheet, a paperboard, a thick resin sheet, or the like can be used.

[0021] In the illustrated example, the second packaging material 3 has a substantially rectangular board shape having a length and a width.

[0022] A fastening hole 5, which will be described later, is formed in the middle of the length of the second packaging material 3. On either side of this fastening hole 5, a crease 3b is provided along the width direction of the second packaging material 3. The space between these two creases 3b functions as the seat portion 3a.

[0023] The space between one of the two lines 3b and an edge portion 3d along one width direction of the second packaging material 3, and the space between the other of the two lines 3b and an edge portion 3d along the other width direction of the second packaging material 3, each function as the side portion 3c (see Figure 1).

[0024] The two side surface portions 3c have the same length. In the illustrated example, an additional line 3f is provided along the width direction of the second packaging material 3 on the end portion 3e side opposite to the connection side with the seat portion 3a of the two side surface portions 3c.

[0025] The second packaging material 3 can be folded by using the creases 3b so that the two side portions 3c are raised in a direction that crosses the seat portion 3a (see FIG. 7). At the same time, the end portion 3e side of the raised side portion 3c can be folded inward and sideways by using the additional creases 3f so that a portion 3g of the end portion 3e located beyond the additional creases 3f faces the seat portion 3a (see FIG. 8).

[0026] In the illustrated example, notches 3h are provided at the locations where the creases 3b and the additional creases 3f are formed, respectively, to reduce the width dimension of the second packaging material 3 at these locations. The notches 3h are formed by removing mountain-shaped areas with their tips facing toward a virtual center line x (see FIG. 1) along the length direction of the second packaging material 3, and are provided at each of two longitudinal side portions 3j of the second packaging material 3. The creases 3b and the additional creases 3f are formed across the space between the two notches 3h.

[0027] In the illustrated example, the fastening member 4 is planar and rigid like the second packaging material 3. In the illustrated example, the fastening member 4 is obtained by breaking a part of the second packaging material 3 as described later.

[0028] The second packaging material 3 also has a fastening hole 5 in the seat portion 3a. In the illustrated example, the fastening hole 5 has an elongated elliptical shape penetrating the second packaging material 3. The fastening hole 5 is formed along an imaginary straight line y (see FIG. 1) that is perpendicular to the imaginary center line x at a position midway in the length direction of the second packaging material 3.

[0029] The second packaging material 3 has through holes 6 at two locations on the side of the side 3c connected to the seat surface 3a and on the opposite end 3e side, through which a part of the first packaging material 2 can pass. In the illustrated example, the through holes 6 are circular holes penetrating the second packaging material 3. In the illustrated example, the center 6a of the through hole 6 is located on the virtual center line x. The additional crease 3f is also provided along a virtual line (not shown) along the width direction passing through a position between the center 6a of the through hole 6 and the hole edge 6b located on the crease 3b side of the through hole 6. As a result, when the end 3e side of the side surface portion 3c is folded using the additional crease 3f as described above, a part of the through hole 6 passes vertically through a portion 3g located beyond the additional crease 3f at the end 3e, and the remaining part of the through hole 6 passes horizontally through the side surface portion 3c (see FIG. 7).

[0030] In this embodiment, the fastening member 4 positioned on the first packaging material 2 can be passed through the fastening hole 5 together with a part of the first packaging material 2 (see Figure 4), and after this passage, the orientation of the fastening member 4 can be changed so that the fastening member 4 can be hooked onto the seat portion 3a on the back side of the seat portion 3a (see Figure 5).

[0031] More specifically, the maximum length of the fastening member 4 is set to be greater than the width of the fastening hole 5 and equal to or smaller than the length of the fastening hole 5; The thickness of the fastening member 4 is equal to or smaller than the width of the fastening hole 5.

[0032] In the illustrated example, the fastening member 4 is disk-shaped with a diameter smaller than the length 5a of the fastening hole 5, a diameter larger than the width 5b of the fastening hole 5, and a thickness smaller than the width 5b of the fastening hole 5.

[0033] In this embodiment, a part of the second packaging material 3 located inside the breakable linear connecting portion 3i formed on the second packaging material 3 becomes the fastening member 4 by breaking the linear connecting portion 3i, and the through hole 6 is formed by the breaking. In the illustrated example, right The through hole 6 on the side is formed by such breaking.

[0034] In the illustrated example, the linear connecting portion 3i consists of two semicircular arc-shaped cuts that penetrate the second packaging material 3 and a seam formed between the two cuts, and by breaking the seam, a disk-shaped fastening member 4 is generated from the second packaging material 3 (see Figure 1).

[0035] With this configuration, the fastening member 4 can be passed through the fastening hole 5 together with the first packaging material 2 in a state where the plate surface of the fastening member 4 is oriented perpendicular to the front surface 3k of the second packaging material 3. After this passage, the fastening member 4 is turned so that the plate surface of the fastening member 4 faces the rear surface 3m of the second packaging material 3, and the fastening member 4 is attached to the seating surface 3a on the rear side of the seating surface 3a. First packaging material 2 It can be hooked with a part of it interposed (see Figs. 4 to 6).

[0036] According to the packaging material 1 of this embodiment, by rationally combining the first packaging material 2 and the second packaging material 3 as two types of packaging materials with different properties, it is possible to hold multiple packaged items M of different sizes, thicknesses, shapes, etc. together without any roughness. That is, (1) by hooking the fastening member 4 onto the seat portion 3a of the second packaging material 3 as described above, the first packaging material 2 can be positioned on the second packaging material 3 and the two can be integrated together (see FIG. 6). (2) Next, the object M can be wrapped with the first packaging material 2 placed on the second packaging material 3, and further, by tying corners 2a of the first packaging material 2, which are typically located opposite each other, to make a knot 2b in the wrapped state, the object can be held on the seating surface 3a of the second packaging material 3 via the first packaging material 2. Even if there are multiple objects M to be packaged, the first packaging material 2 can wrap the multiple objects M together without leaving any gaps between them (see FIG. 7). (3) Next, the two side portions 3c of the second packaging material 3 are raised, and a part of the first packaging material 2 (typically a corner 2a other than the previously tied corner 2a) is passed through the through hole 6 provided in one of the two side portions 3c from the inside of the side portion 3c and drawn out to the outside, and another part of the first packaging material 2 (typically a corner 2a other than the previously tied corner 2a) is passed through the through hole 6 provided in the other of the two side portions 3c from the inside of the side portion 3c and drawn out to the outside, and then the drawn part and the other part are tied to make a knot 2b. This allows the first packaging material 2 and the second packaging material 3 to be integrated even at the end 3e of the side portion 3c while the side portions 3c are positioned on the left and right of the packaged item M positioned on the seat portion 3a of the second packaging material 3 (see FIG. 8). (4) The packaging material 1 containing the object M to be packed in this manner can be placed inside the outer box 7 without any roughness thanks to the second packaging material 3. In addition, since the first packaging material 2 is integrated with the second packaging material 3 at two locations, the seat portion 3a and the end portion 3e of the side portion 3c, the object M to be packed does not become rough even inside the second packaging material 3. Furthermore, even if there are multiple objects M to be packed, they can be placed inside the first packaging material 2 without any roughness (see FIG. 8).

[0037] (Second example) The packaging material 1 according to the second example differs from the packaging material 1 according to the first example in that a fastening member 4 is adhered to the center of a first packaging material 2 to integrate the two.

[0038] In the second example, the fastening member 4 has an oval shape having a length and a width. The fastening member 4 is integrated with the first packaging material 2 by adhering one surface of the fastening member 4 to the center of the first packaging material 2.

[0039] The fastening hole 5 of the second packaging material 3 is a rectangular through hole whose length direction is aligned with the width direction of the second packaging material 3. The length 5a of the fastening hole 5 is smaller than the length of the fastening member 4, so that the fastening member 4 can be inserted into the fastening hole 5 from its width side edge but cannot be inserted from its length side edge. As a result, in this second example, when the fastening member 4 is passed through the fastening hole 5 and hooked, one of the diagonal lines L of the rectangular first packaging material 2 is aligned with the length direction of the second packaging material 3 (see FIG. 14), and the through hole 6 of the side portion 3c of the second packaging material 3 is positioned on this diagonal line L, so that after the side portion 3c is raised, the first packaging material 2 can be smoothly passed through the through hole 6 from the corner portion 2a positioned on the diagonal line L. Furthermore, as shown in Figure 18, if the first packaging material 2 is folded so that the fastening member 4 is positioned at one corner of the first packaging material 2 folded into a square so that the first packaging material 2 is essentially one-quarter of its original size, the fastening member 4 can be smoothly passed through the fastening hole 5 of the second packaging material.

[0040] As shown in Fig. 12, the fastening member 4 adhered to the first packaging material 2 is passed through the fastening hole 5 of the second packaging material 3, and then, as shown in Fig. 13, the surface opposite to the adhered side of the fastening member 4 is turned so as to face the back surface 3m of the seating surface portion 3a of the second packaging material 3, and the two are integrated in a state in which the surface 3k of the second packaging material 3 is covered with the first packaging material 2 (Fig. 14). From this state, the object M to be packaged is placed on the seating surface portion 3a of the second packaging material 3, and the corners 2a of the first packaging material 2 that do not pass through the through hole 6 are tied together on the object M to be packaged, and then the side portion 3c of the second packaging material 3 is raised to pass the corners 2a located on the diagonal line L through the through hole 6 and tied, thereby packaging the object M with the packaging material 1 (Figs. 15 to 16).

[0041] In the illustrated example, the tabs 8 are connected to both the left and right sides of the side portion 3c (the two sides 3j of the second packaging material 3) via the additional crease 9, and the seating surface 3a side of the packaging material 1 with the packaged object M placed on the seating surface 3a is inserted into the outer box until the tabs 8 are caught by the box opening 7a of the outer box 7, so that the packaging material 1 can be combined with the outer box 7 in a state in which the side portion 3c is raised by the outer box 7 (see FIG. 16). The tabs 8 are provided at a position between the crease 3b and the additional crease 3f. This allows the operation of passing a part of the first packaging material 2 through the through hole 6 of the raised side portion 3c and the operation of making the knot 2b as described above after the passage to be performed smoothly. After the work is completed, the tab portion 8 is folded along the additional crease 9 so as to be perpendicular to the side portion 3c, and the package material 1 with the packaged item M packed therein can be dropped into the outer box 7 to release the catch (FIG. 17). In the illustrated example, the seat portion 3a has a shape and size substantially equal to the cross-sectional shape of the outer box 7, and the tab portion 8 is folded along the additional crease 11 on both the left and right sides of the seat portion 3a (the two side portions 3j of the second package material 3). 10 The tab portion is connected by folding along the additional crease 11. 10 The packaging material 1 can be placed in the outer box only when the tab is raised. 10 The tab portion has a length extending in the width direction of the seat portion 3a. 8 This prevents buckling of the seating surface portion 3a due to the weight of the item M when the seating surface portion 3a is hooked onto the opening 7a of the outer box 7 (FIG. 16).

[0042] The remaining configuration of the second example is substantially the same as that of the first example, so the same reference numerals as those used in FIGS. 1 to 8 showing the first example are used in FIGS. 9 to 18 showing the second example, and the description thereof will be omitted.

[0043] (Third example) In the packaging material 1 of the third example, the center of the first packaging material 2 is bonded to the center of the seating surface 3a of the second packaging material 3 of the second example, thereby integrating the two, and as a result, no through-hole 6 is provided in the center of the second packaging material 3, and the fastening member 4 is omitted. In Fig. 19, the bonding point is indicated by the reference symbol 12.

[0044] As a result, even with this packaging material 1, (1) the packaged item M can be wrapped with the first packaging material 2 positioned on the second packaging material 3, and further, by tying corners 2a, which are typically located at opposing positions, of the first packaging material 2 in the wrapped state to make a knot 2b, the packaged item M can be held on the seating surface 3a of the second packaging material 3 via the first packaging material 2. Even if there are multiple packaged items M, the first packaging material 2 can wrap the multiple packaged items M together without leaving any gaps between them. (2) Next, the two side portions 3c of the second packaging material 3 are raised, and a part of the first packaging material 2 is passed from the inside of the side portion 3c through the through hole 6 provided in one of the two side portions 3c and drawn out to the outside, and another part of the first packaging material 2 is passed from the inside of the side portion 3c through the through hole 6 provided in the other of the two side portions 3c and drawn out to the outside, and then the drawn part and the other part are tied together to make a knot 2b. This allows the first packaging material 2 and the second packaging material 3 to be integrated even at the end 3e of the side portion 3c while the side portions 3c are positioned on the left and right of the packaged item M positioned on the seat portion 3a of the second packaging material 3. (3) The packaging material 1 containing the object M to be packed in this manner can be placed inside the outer box 7 without any roughness thanks to the second packaging material 3. In addition, since the first packaging material 2 is integrated with the second packaging material 3 at two locations, the seat portion 3a and the end portion 3e of the side portion 3c, the object M to be packed does not become rough even inside the second packaging material 3. Furthermore, even if there are multiple objects M to be packed, they can be placed inside the first packaging material 2 without any roughness.

[0045] The remaining configuration of the third example is substantially the same as that of the second example, so the same reference numerals as those used in FIGS. 9 to 18 showing the second example are used in FIG. 19 showing the third example, and description thereof will be omitted.

[0046] Of course, the present invention is not limited to the above-described embodiments, but includes all embodiments that can achieve the object of the present invention. [Explanation of symbols]
