Summary of the Invention

Problems to be Solved by the Invention

[0004] In the case of a product (object) having an elliptical outer peripheral surface, since the contact area of the object with respect to the mount is relatively large, it is possible to easily join and hold the object to the mount with sufficient strength. However, in the case of a product (object) having an outer peripheral surface with a substantially circular cross-sectional shape in the radial direction, the contact area of the object with respect to the mount becomes small, and it becomes difficult to join and hold the object to the mount with sufficient strength.

[0005] The present invention has been made in view of the above problems, and its objective is to provide a packaging body that can be joined and held to a backing card with sufficient strength, even if the object has an outer surface having a substantially circular cross-sectional shape in the radial direction. [Means for solving the problem]

[0006] To achieve the above objective, the present invention provides a packaging body comprising a backing board, a resin film covering an object having an outer surface with a substantially circular cross-sectional shape in the radial direction, and a joining body that joins the film covering the object to one side of the backing board, wherein the backing board has a receiving groove formed on one side that curves along the outer surface of the object and accommodates a part of the object, and the joining body is provided inside the receiving groove.

[0007] Furthermore, in the packaging according to the present invention, it is preferable that the cardboard backing has fold lines formed on the other side that divide it into a flat portion forming a flat surface and the storage groove.

[0008] Furthermore, in the packaging according to the present invention, it is preferable that the joining body, in the above-described packaging, joins the film to the receiving groove of the backing paper such that the joining body holds the circumferential direction of the target object with a length of 10% to 50% of the circumferential length of the outer surface of the target object.

[0009] Furthermore, in the packaging according to the present invention, it is preferable that the joining body, in the above-described packaging, joins the film to the receiving groove of the backing paper such that the joining body holds the axial direction of the target object with a length of 20% to 100% of the length along the axial direction of the target object. [Effects of the Invention]

[0010] According to the packaging of the present invention, an object having an outer surface with a substantially circular cross-sectional shape in the radial direction is attached to the inside of a curved storage groove along the outer surface of the object by a bonding body via a film. As a result, the backing paper can bond and hold the object with a relatively large contact area. This allows the object to be bonded and held to the backing paper with sufficient strength, even if the outer surface has a substantially circular cross-sectional shape in the radial direction.

[Modes for carrying out the invention]

[0012] Embodiments of the packaging according to the present invention will be described with reference to the drawings. It should be noted that the present invention is not limited to the embodiments described below with reference to the drawings, and various technical matters described in each embodiment can be combined or replaced as needed.

[0013] [Main Implementations] The main embodiments of the packaging according to the present invention will be described with reference to Figures 1 to 4.

[0014] <Package> As shown in FIGS. 1 to 4, the package 100 according to the present embodiment includes a mount 111, a resin film 112 that covers an object 101 such as a product having an outer peripheral surface whose radial cross-sectional shape is substantially circular, and a double-sided adhesive tape 113 that is a bonding body for bonding the film 112 covering the object 101 to the surface 111A which is one surface of the mount 111.

[0015] 〈Object 101〉 The object 101 is a product having an outer peripheral surface whose radial cross-sectional shape is substantially circular, and examples thereof include insect repellents and insecticides in which a cap 101b is placed on a spray-type cylindrical main body container 101a.

[0016] 〈Mount 111〉 The mount 111 has a flat rectangular shape, and a storage groove 111a that curves along the cylindrical outer peripheral surface of the object 101 and accommodates a part of the object 101 is formed on the surface 111A. Further, the mount 111 has a fold line 111c that divides the flat part 111b forming a flat surface and the storage groove 111a, and is formed on the back surface 111B which is the other surface. In FIGS. 1 and 4, 111d is a hole for hanging.

[0017] 〈Film 112〉 The film 112 is made of a resin such as polyolefin such as polyethylene (PE) or polypropylene (PP), polyester such as polyethylene terephthalate (PET), or polystyrene (PS), and has a bag shape. When the object 101 is placed inside and heated, it shrinks (shrinks) and adheres to the object 101, and becomes a shrink film that can hermetically cover the object 101.

[0018] 〈Double-sided adhesive tape 113〉 The double-sided adhesive tape 113 is adhered inside the storage groove 111a of the backing paper 111. Preferably, the double-sided adhesive tape 113 joins the film 112 to the storage groove 111a of the backing paper 111 so as to hold the circumferential direction C of the object 101 with a length Lc that is 10% or more and 50% or less of the length of the circumferential direction C of the object 101. More preferably, it is 20% or more and 40% or less, and even more preferably, it is 25% or more and 35% or less. If it is less than 10%, it becomes difficult to join and hold the object 101 to the backing paper 111 with sufficient strength, which is not preferable. If it exceeds 50%, it joins and holds with more strength than necessary, which tends to be wasted and is not preferable.

[0019] Also, preferably, the double-sided adhesive tape 113 joins the film 112 to the storage groove 111a of the backing paper 111 so as to hold the axial direction A of the object 101 with a length La that is 20% or more and 100% or less of the length along the axial direction A of the object 101. More preferably, it is 30% or more and 90% or less, and even more preferably, it is 50% or more and 80% or less. If it is less than 20%, it becomes difficult to join and hold the object 101 to the backing paper 111 with sufficient strength, which is not preferable. If it exceeds 100%, it joins and holds with more strength than necessary, which tends to be wasted and is not preferable.

[0020] <Procedure for manufacturing the package 100> The package 100 according to such an embodiment is manufactured as follows. First, holes 111d are formed in the backing paper 111, and folding lines 111c are formed on the back surface 111B so as to be paired. These folding lines 111c can be easily formed by linearly pressing and indenting from the back surface 111B side of the backing paper 111. As a result, the backing paper 111 becomes easily bendable to the back surface 111B side along the folding lines 111c.

[0021] Next, double-sided adhesive tape 113 is applied to the surface 111A of the backing paper 111 so that it is positioned between the pair of fold lines 111c. Subsequently, a roller or the like with a surface covered with fluororesin is used to press from the surface 111A side between the pair of fold lines 111c, thereby embossing a recessed receiving groove 111a that curves along the outer surface of the object 101 between the pair of fold lines 111c.

[0022] In this case, since the surface of the roller is covered with fluororesin, the roller will not stick to the double-sided adhesive tape 113. Also, since the fold line 111c is formed on the back surface 111B of the backing paper 111, the storage groove 111a can be formed to be properly partitioned, and the flat portion 111b can be positioned to open towards the back surface 111B, preventing the backing paper 111 from becoming V-shaped.

[0023] On the other hand, in parallel with this, the object 101 is placed inside the bag-shaped film 112, and the film 112 is heated to shrink it, thereby sealing and covering the object 101 with the film 112.

[0024] Then, the object 101, which has been sealed and covered with film 112, is placed inside the receiving groove 111a of the backing paper 111 and attached to the double-sided adhesive tape 113 to form the package 100.

[0025] <Effects> In the packaging 100 produced in this manner, a cylindrical object 101 having an outer surface with a substantially circular radial cross-sectional shape is attached to the inside of a receiving groove 111a that curves along the outer surface of the object 101 via a film 112 and double-sided adhesive tape 113. Therefore, the backing paper 111 can join and hold the object 101 with a relatively large contact area.

[0026] Therefore, according to the packaging body 100 of this embodiment, even if the object 101 has an outer surface with a substantially circular cross-sectional shape in the radial direction, it can be joined and held to the backing paper 111 with sufficient strength.

[0027] Furthermore, since the fold line 111c is formed on the back surface 111B of the backing sheet 111, the flat portion 111b can be positioned to open towards the back surface 111B, preventing the backing sheet 111 from becoming V-shaped and thus preventing a decrease in the visibility of text, images, etc. on the surface surface 111A of the backing sheet 111.

[0028] <Half-cut double-sided adhesive tape 113> Incidentally, it is highly preferable to use a double-sided adhesive tape 113 that has been pre-cut in half. As shown in Figure 5, this is a double-sided adhesive tape 113 that has been cut in half into small pieces 113a at specified intervals along the longitudinal direction, and examples include the one described in Patent Document 2 above.

[0029] The automatic application device for half-cut double-sided tape described in Patent Document 2 above applies the half-cut double-sided tape with a liner, unwound from a winding body, to a backing sheet using an application roller to adhere the double-sided adhesive tape (only) to the backing sheet. While the half-cut double-sided tape is in contact with the backing sheet to be applied, small pieces are successively attached to the top surface of the backing sheet as the application roller rotates due to its relative movement to the backing sheet. However, when the half-cut double-sided tape separates from the backing sheet, the small piece of tape that was in contact with the backing sheet just before the separation is cut, and the remaining pieces of tape remain on the liner.

[0030] Such pre-cut double-sided adhesive tape 113 does not require cutting. For example, when applying double-sided adhesive tape using an automated machine, if the tape needs to be cut, the adhesive component will adhere to the cutting edge of the cutting tool (cutting means) when the strip-shaped material with the adhesive attached is cut, reducing the cutting ability of the cutting tool. This would necessitate stopping the manufacturing equipment and removing the adhesive component from the cutting edge.

[0031] In contrast, the pre-cut double-sided adhesive tape 113 does not require cutting, and therefore does not cause the problems described above. Note that the pre-cut double-sided adhesive tape 113 shown in Figure 5 has a wavy, mountain-shaped half-cut line on the small piece 113a, but there are also tapes with half-cut lines of other shapes.

[0032] [Other embodiments] In the embodiment described above, the target object 101 was placed inside a bag-shaped film 112, the film 112 was heated to shrink it and seal the target object 101 with the film 112, and then the package 100 was made by placing it inside the receiving groove 111a of the backing paper 111 and attaching it to the double-sided adhesive tape 113. However, the present invention is not limited to this.

[0033] In another embodiment, for example, a cylindrical film can be attached to the double-sided adhesive tape 113 on the inside of the storage groove 111a of the cardboard backing 111, then the object 101 can be placed inside the film, and the film can be heated to shrink it and seal the object 101 with the film to produce a package.

[0034] Furthermore, while the above-described embodiment described a case of a packaging body 100 in which double-sided adhesive tape 113 is continuously provided in the accommodating groove 111a of the backing 111 in the axial direction A of the target object 101, the present invention is not limited to this. As another embodiment, for example, it is also possible to have a packaging body in which double-sided adhesive tape 113 is intermittently provided in the accommodating groove 111a of the backing 111 in the axial direction A of the target object 101.

[0035] Furthermore, while the above-described embodiment described a case in which double-sided adhesive tape 113 is continuously provided in the receiving groove 111a of the backing 111 in the circumferential direction C of the target object 101, the present invention is not limited to this. As another embodiment, for example, it is also possible to have a packaging in which double-sided adhesive tape 113 is intermittently provided in the receiving groove 111a of the backing 111 in the axial direction A of the target object 101.

[0036] Furthermore, although the above-described embodiment described a case in which a double-sided adhesive tape 113 is used as the bonding agent for the packaging 100, the present invention is not limited to this. In other embodiments, it is also possible to use a packaging in which, for example, an adhesive or hot melt is used as the bonding agent instead of the double-sided adhesive tape 113.

[0037] Furthermore, while the above-described embodiment described a case of a packaging body 100 using a backing sheet 111 in which a fold line 111c dividing the flat portion 111b and the storage groove 111a is formed on the back surface 111B, the present invention is not limited to this. As another embodiment, for example, it is also possible to use a packaging body using a backing sheet in which the fold line 111c is omitted.

[0038] However, as described above, a packaging body 100 using a backing sheet 111 with a fold line 111c formed on the back surface 111B that divides the flat portion 111b and the storage groove 111a is highly preferable because, as explained earlier, the storage groove 111a can be properly divided, and the flat portion 111b can be positioned to open towards the back surface 111B, preventing the backing sheet 111 from becoming V-shaped.

[0039] Furthermore, although the above-described embodiment described the case of a packaging body 100 applied to a cylindrical object 101, the present invention is not limited to this. As for other embodiments, the present invention can be applied in the same manner as in the above-described embodiment to any object having an outer surface with a substantially circular radial cross-sectional shape, such as a cone shape or a frustocone shape, as well as a gourd shape with a constricted central portion in the axial direction, a rugby ball shape with a larger diameter closer to the center than at both ends in the axial direction, or a banana shape that is curved in the axial direction. [Industrial applicability]

[0040] The packaging according to the present invention can be joined and held to the backing paper with sufficient strength, even if the object has an outer surface with a substantially circular cross-sectional shape in the radial direction, and therefore can be used very effectively in various industries.
