Abstract

The present invention provides a packaging structure that allows the packaged goods and the film covering them to stand upright without touching the surface where they are placed. [Solution] When a package is formed by attaching a shrink film 4 covering the packaged item 3 to a backing card 1, the backing card 1 is folded at a right angle to form a folded portion 7, and the shrink film 4 is attached to the backing card 1 at two or more locations including the folded portion 7. The surface (back side) of the backing card 1 at the folded portion 7 functions as a self-supporting function 8, allowing the package to stand upright, thereby enabling the backing card 1 to stand vertically.

Description

Technical Field

[0001] The present invention relates to a package and a method for opening the same, and more particularly to a package in which a film package in which an object to be packaged is packaged with a film is adhered to a paper sheet member such as a mount, and a method for opening the same.

Background Art

[0002] For example, in order to display a product having an outer peripheral surface formed of a curved surface such as a cylindrical outer peripheral surface, it is effective to suspend and display the product. In Patent Document 1 below, a cylindrical shrink film is joined to the surface of a mount by joining means such as an adhesive, an adhesive tape, or heat welding to form a mount with a shrink film. For example, a product (object to be packaged) having a cylindrical outer peripheral surface is accommodated in the cylinder, and the shrink film is heat-shrunk to disclose a package in which the object to be packaged is attached to the mount. The package can be suspended and displayed by passing a beam-shaped rod member through a hole provided in the upper part of the mount.

Summary of the Invention

Problems to be Solved by the Invention

[0004] This type of packaging, in which film packaging is laminated to a sheet material such as cardboard, cannot always be hung for display; sometimes it is necessary to display it upright on a shelf, for example. In particular, if the packaged goods are relatively heavy, hanging many of these packages on a display stand may cause the hanging rods to bend or the stand to tip over. In such cases, it is better to display the packages upright. However, it is undesirable to allow the packaged goods or the film covering them to touch the surface they are placed on.

[0005] The present invention has been made in view of the above problems, and its purpose is to provide a packaging body that can stand upright without the packaged item or the film covering it touching the surface it is placed on, and a method for opening the same. [Means for solving the problem]

[0006] To achieve the above objective, one embodiment of the present invention is a packaging body in which a film covering the packaged item is attached to a paper sheet member, thereby bonding the packaged item to the sheet member, wherein the sheet member has a folded portion formed by bending the sheet member, the film is attached to the sheet member at two or more locations including the folded portion, and the surface or edge of the sheet member at the folded portion constitutes a self-supporting function that causes the sheet member other than the folded portion to stand upright in the vertical direction.

[0007] Furthermore, in a further aspect of the present invention, the folded portion is characterized in that it is folded at a right angle to the sheet member other than the folded portion. Furthermore, in a further aspect of the present invention, a self-supporting function is formed on the surface of the sheet member at the folded portion, and a cut is provided along the fold line of the folded portion that penetrates the sheet member in the area where the packaged item is located.

[0008] To open this package, the packaged item, to which the film is attached at the fold, is pushed toward the sheet material, tearing the sheet material from the cut, and then the torn portion is pulled toward the opposite side of the packaged item, which tears the sheet material along with the film attached to it. [Effects of the Invention]

[0009] According to the present invention, the package can be made to stand upright without the packaged item or the film covering it touching the surface it is placed on. [Brief explanation of the drawing]

[0011] The embodiments of the packaging body of the present invention will be described in detail below with reference to the drawings. The embodiments shown below are illustrative of configurations and methods for realizing the technical idea of ​​the present invention, and the technical idea of ​​the present invention is not limited to the following embodiments in terms of the material, shape, structure, arrangement, etc. of the components. Furthermore, the drawings are schematic. Therefore, it should be noted that the relationship and ratio of thickness and planar dimensions may differ from those in reality, and there may be parts where the dimensional relationships and ratios differ between drawings.

[0012] The packaging of the first embodiment shown in Figure 1 has a film packaging 2 laminated to one side of a paper sheet material, a cardboard base 1. The film packaging 2 is made by wrapping a packaged item 3, such as a consumable product, with shrink film 4. In this example, the entire circumference of the packaged item 3 is covered with shrink film 4. The actual shrink film 4 is very thin and adheres almost tightly to the packaged item 3, which is schematically shown here. The packaged item 3 in this embodiment is, for example, a rectangular parallelepiped shape that is elongated vertically, as shown in the front view of Figure 1, and its rectangular cross-section is slightly wider than its depth, as shown in the plan view of Figure 1. The product (packaged item 3), such as a consumable product, is packaged by laminating the film packaging 2 to the cardboard base 1. In this embodiment, the product can be hung and displayed by passing a beam-shaped rod member through a hole 11 provided at the top of the cardboard base 1, or it can be displayed freestanding on a display stand or other location. In this example, the only requirement is that the packaged item 3 does not easily detach from the cardboard backing 1, so the shrink film 4 does not necessarily have to cover the entire surface of the packaged item 3. Furthermore, the film may be something other than shrink film 4. Also, "paper-based" includes not only paper itself, but also materials primarily composed of paper.

[0013] As shown in Figure 2a, the cardboard backing 1 used in this embodiment has two crease lines 6, called fold lines, that run continuously along the entire length in the short direction, near the end opposite the hole 11 in the longitudinal direction of the rectangular cardboard backing 1 in plan view. The cardboard backing 1 is valley-folded along these crease lines 6. In the figure, the crease lines 6 that make up the valley fold line are shown as dashed lines. These crease lines 6 are formed by linearly compressing the cardboard backing 1 in the thickness direction, causing linear indentations in the paper material. These indentations become weak points, making the cardboard backing 1 easier to fold. Although difficult to see in the figure, a notch 9 that penetrates the cardboard backing 1 is provided along the crease line 6 in the center of the cardboard width direction near the hole 11, i.e., in the area where the film packaging 2 is located (see Figure 4a). When laminating the film packaging 2 to this cardboard backing 1, double-sided tape 5 is first applied to the cardboard backing 1 in a predetermined direction for a predetermined length, as shown in Figure 2b. As will be described later, half-cut double-sided tape 5 is used for this double-sided tape 5, and the direction of application of this double-sided tape 5 is the direction that intersects with the direction of application of the grid lines 6, preferably perpendicular to it. One end of the application direction of this double-sided tape 5 is positioned approximately at the center of the width direction of the backing paper 1, on the end opposite to the hole 11, and the double-sided tape 5 is applied to the backing paper 1 from there toward the direction of the hole 11. The direction in which the double-sided tape 5 is applied to the backing paper 1 may be any direction along the length of the tape.

[0014] Then, as shown in Figure 2c, the elongated packaged object 3 (film packaged object 2) is attached to the double-sided tape 5 such that its longitudinal direction coincides with the continuous attachment direction of the double-sided tape 5, and one side in the depth direction (hereinafter also referred to as the back of the film packaged object 2) faces the backing paper 1. In essence, the shrink film 4 covering the packaged object 3 is attached to the double-sided tape 5, and the film packaged object 2 (packaged object 3) is attached to the backing paper 1. One end of the film packaged object 2 (packaged object 3) in the longitudinal direction, specifically the end that will be facing downwards when the packaged object 3 is visible (hereinafter also referred to as the bottom of the film packaged object 2), is positioned at the scribe line 6 close to the hole 11 (or slightly closer to the hole 11). Next, as shown in Figure 2d, the backing paper 1 is folded in a valley fold at the scribe line 6 close to the hole 11. This creates a folded portion 7 in the backing paper 1. The folded portion 7 is folded at a right angle to the original backing paper 1. Double-sided tape 5 is also attached to this folded portion 7, and this double-sided tape 5 on the folded portion 7 is attached to the bottom of the film packaging 2.

[0015] Next, as shown in Figure 2e, the backing paper 1 is folded towards the film packaging 2 at the position of the scribed line 6 furthest from the hole 11. This scribed line 6 furthest from the hole 11 becomes a mountain fold line, indicated by a dashed line in the figure. That is, the folded portion at this mountain fold line forms a second folded portion 10, which is further folded at the tip of the previous folded portion 7. This second folded portion 10 is folded at a right angle to the folded portion 7, and as a result becomes parallel to the original backing paper 1. Double-sided tape 5 is also attached to this second folded portion 10, and the double-sided tape 5 on this second folded portion 10 is attached to the side opposite to the back of the film packaging 2, i.e., the front of the film packaging 2. This second folded portion 10 is configured so that when the film packaging 2 (packaged item 3) is viewed from the front, the so-called back side of the backing paper 1 is visible. Therefore, by displaying designs, text, etc., in advance in the area corresponding to the second fold portion 10 on the back of the backing sheet 1, they will be visible from the front of the packaging. Alternatively, as will be described later, by pushing the film packaging 2 (packaged item 3) towards the backing sheet 1 at this second fold portion 10, the backing sheet 1 and shrink film 4 can be torn and the packaged item 3 can be removed, so this fact may also be indicated.

[0016] In the package configured as described above, as shown in FIG. 1, the bent portion 7 of the mount 1 constitutes the bottom (bottom surface) as a package that covers the bottom of the film package 2 (the packaged item 3). Since the bent portion 7 corresponding to this bottom is bent at a right angle with respect to the mount 1, when the package is made to stand on the bent portion 7 as the bottom, the mount 1 originally stands in the vertical direction. That is, in this embodiment, the surface (bottom surface) of the bent portion 7 that becomes the bottom of the package becomes the self-standing functional portion 8 of the package. Further, since this bent portion 7 covers the bottom of the film package 2, the shrink film 4 and the packaged item 3 do not touch the placement location when the package is made to stand. In addition, the bent portion 7 and the second bent portion 10 also have a function of protecting the shrink film 4 and the packaged item 3 when the package falls to the placement location or when the bottom surface or the surface is rubbed. [[ID=四]]

[0017] When removing the packaged item 3 from this packaging, as shown in Figure 3a, the film packaging 2 (packaged item 3) is pushed from the front side of the second folded portion 10 toward the back side of the cardboard backing 1. At the position of the crease line 6 where the folded portion 7 is folded from the cardboard backing 1, a cut 9 is provided along the crease line 6 in the area where the packaged item 3 is located. As shown in Figure 3b, when the film packaging 2 (packaged item 3) is pushed toward the cardboard backing 1 from the front side of the second folded portion 10, the cardboard backing 1 tears at this cut 9 by the width of the packaged item 3. At this time, since the cardboard backing 1 is attached to the shrink film 4, the portion of the shrink film 4 attached to the torn cardboard backing 1 is torn away from the other film portions. In this state, as shown in Figure 3c, for example, the fingertip of a finger is inserted between the shrink film 4 attached to the torn cardboard backing 1 and the packaged item 3, and the torn portion of the cardboard backing 1 is pulled toward the opposite side of the packaged item 3. As a result, as shown in Figure 3d, the backing paper 1 tears along the width of the packaged item 3, and the shrink film 4 attached to the backing paper 1 is torn away from the packaged item 3, tearing from other film portions. Consequently, the portion of the shrink film 4 attached to the double-sided tape 5 is torn away from the surrounding portion along the double-sided tape 5, and the portion of the packaged item 3 on the backing paper 1 side is exposed from the shrink film 4 (the bag-like portion). Once the portion of the packaged item 3 on the backing paper 1 side is exposed in this way, the packaged item 3 is removed from the bag-like wrapping portion of the shrink film 4.

[0018] As described above, in this embodiment, a half-cut double-sided tape is used for the double-sided tape 5. As shown in FIG. 4, the half-cut double-sided tape is obtained by half-cutting the double-sided tape 5 into small pieces at predetermined intervals along the longitudinal direction, and is disclosed in, for example, Patent Document 2 mentioned above. The automatic sticking device for the half-cut double-sided tape described in this patent document presses the half-cut double-sided tape with a liner unwound from a winding body against the base sheet 1 by a sticking roller to stick only the double-sided tape 5 to the base sheet 1. While the half-cut double-sided tape is in contact with the base sheet 1 which is the object to be pasted, small pieces of the double-sided tape 5 are successively pasted onto the upper surface of the base sheet 1 as the sticking roller rotates due to the relative movement between the double-sided tape 5 and the base sheet 1. However, when the half-cut double-sided tape separates from the base sheet 1, the small pieces of the double-sided tape 5 are cut at the half-cut position of the double-sided tape 5 which had been in contact with the base sheet 1 until just before, and the subsequent small pieces of the double-sided tape 5 remain on the liner. In the half-cut double-sided tape of FIG. 4, the half-cut line is in a mountain-shaped wave form, but there are also those with other half-cut lines.

[0019] As mentioned above, pre-cut double-sided tape eliminates the need for a cutting step of the double-sided tape 5. For example, when performing the double-sided tape application process shown in Figure 2b using an automated machine, if the process includes cutting the double-sided tape 5, the cutting of the double-sided tape 5 will take even a small amount of time, making it difficult to manufacture the packaging shown in Figure 2 within a short cycle time. In addition, when cutting a strip-shaped material with adhesive components attached, such as double-sided tape 5, the adhesive components can adhere to the cutting edge of the cutting tool (cutting means), causing the blade to become dull. When the blade becomes dull, the manufacturing equipment must be stopped and the adhesive components removed from the blade. Since pre-cut double-sided tape eliminates the need for a cutting step of the double-sided tape 5, these problems do not occur. Furthermore, this pre-cut double-sided tape can be easily separated from the half-cut line even when it is attached to the object to be attached, such as the backing paper 1. Therefore, when removing the packaged item 3 from the packaging, as described above, even if the cut 9 is misaligned from the half-cut line, as shown in Figure 4, the double-sided tape 5 will separate from the backing paper 1 at the nearest half-cut line. Note that the actual double-sided tape 5 is so thin that it is not visible when viewing the packaging from the side or above. Figures 1 and 3 schematically show the double-sided tape 5. In addition, adhesives or heat sealants may be used instead of the double-sided tape 5 to attach the film packaged item 2 to the backing paper 1.

[0020] Figure 5 shows a three-view drawing of a modified version of the packaging shown in Figure 1. The packaged item 3 in this modified version is the same as the packaged item 3 in Figure 1. This modified packaging is similar to the packaging in Figure 1, but as is clear from the figure, this packaging does not have a second fold, and the fold 7 protrudes from the film packaging 2 on the opposite side (front side) from the backing paper 1. When manufacturing this packaging, as shown in Figure 6a, the film packaging 2 is attached to the backing paper 1 with the bottom of the film packaging 2 aligned with the score line 6. Then, the backing paper 1 is folded along the score line 6, and as shown in Figure 6b, the double-sided tape 5 attached to the fold 7 is attached to the bottom of the film packaging 2, thus attaching the fold 7 to the film packaging 2. The leading edge of the fold 7 protrudes from the front side of the film packaging 2, but since the double-sided tape 5 is only attached to the bottom of the film packaging 2, the double-sided tape 5 is not visible on this protruding portion. Furthermore, in this modified example, a notch 9 is provided along the score line 6 in the area where the film packaging 2 is located at the position of the score line 6. In this case, the film packaging 2 can be pressed from the front side to the backing paper 1 side (back side) to tear the backing paper 1, and the packaged item 3 can be removed in the same manner as in Figure 3.

[0021] In these embodiments, when a package is formed by attaching a shrink film 4 covering the packaged item 3 to a backing sheet 1, the backing sheet 1 is folded to form a folded portion 7, and the shrink film 4 is attached to the backing sheet 1 at two or more locations, including the folded portion 7, so that the surface (back side) of the backing sheet 1 at the folded portion 7 functions as a self-supporting portion 8. As a result, the package can stand on its own without the packaged item 3 or the shrink film 4 covering it touching the surface it is placed on.

[0022] Furthermore, by folding the folding portion 7 at a right angle to the backing paper 1, the packaging can be made to stand upright on the surface of the folding portion 7, thereby allowing the backing paper 1 to stand vertically. Furthermore, by providing a cut 9 that penetrates the backing paper 1 along the crease line (fold line) 6 where the folded portion 7 is folded, in the area where the packaged item 3 is located, the film packaged item 2 can be pressed against the backing paper 1 and the backing paper 1 can be torn through the cut 9. Then, by pulling the torn portion away from the packaged item 3, the shrink film 4 attached to the backing paper 1 can be torn off together, thereby allowing the packaged item 3 to be removed from the shrink film 4.

[0023] Furthermore, the backing paper 1 is further folded at the bent end of the folded portion 7 to form a second folded portion 10, and the shrink film 4 is attached to the backing paper 1 at this second folded portion 10. This allows the back side of the backing paper 1 to be shown to the front side of the film packaged item 2 (packaged item 3), so for example, this part can be used as a display area to enhance the design, or the shrink film 4 and packaged item 3 can be protected at the second folded portion 10.

[0024] Next, a second embodiment of the packaging of the present invention will be described. Figure 7 is a three-view drawing of the packaging of this embodiment. The packaged item 3 in this embodiment is the same as the packaged item 3 in Figure 1, but a series of film fragile sections are formed in the vertical direction of the front view at the part indicated by arrow A in the plan view of Figure 7. These film fragile sections are made up of perforations pre-provided in the shrink film 4 or very shallow scratches made on the surface of the shrink film 4, and are provided so that the shrink film 4 begins to tear from these film fragile sections. In this embodiment as well, a rectangular cardboard backing 1 that is elongated vertically is used to match the vertically elongated packaged item 3 (=film packaged item 2) in Figure 7, and the back surface of the film packaged item 2 is attached to the surface of the cardboard backing 1 with double-sided tape 5, with the longitudinal direction of the rectangular cardboard backing 1 aligned with the longitudinal direction of the film packaged item 2. In this embodiment, the left portion of the cardboard backing 1 of the film packaged item 2 that is attached to the rectangular cardboard backing 1 is folded towards the front in the front view of Figure 7 to form a folded portion 7. This folded portion 7 is folded at a right angle to the backing paper 1 so as to follow the left side of the rectangular cross-section of the packaged item 3 (film packaged item 2), and in the front view of Figure 7, the lower edge of this folded portion 7 and the lower edge of the backing paper 1 allow the package to stand on its own. In other words, in this embodiment, the edge of the folded portion 7 constitutes part of the self-supporting function portion 8, and the lower edge of the folded portion 7 and the lower edge of the backing paper 1 constitute the self-supporting function portion 8. In this embodiment, the film packaged item 2 is attached to the backing paper 1 such that the bottom of the film packaged item 2 is located very slightly inside the backing paper 1 than the lower edge of the backing paper 1.

[0025] As shown in Figure 8a, the cardboard backing 1 used in the manufacture of the packaging in this embodiment has perforations 12 at the position of the fold line of the folded portion 7. These perforations 12 are provided as a weak point in the cardboard backing to tear when removing the packaged item 3, as described later. However, if the packaged item 3 is not to be removed by tearing the cardboard backing 1 at this position, a fold line such as the aforementioned ruled line may be provided instead of the perforations 12. In addition, double-sided tape 5 is continuously attached to both sides of the cardboard backing 1 along the longitudinal direction of the cardboard backing 1, with the perforations 12 in between. The half-cut double-sided tape described above can be used for this double-sided tape 5. When manufacturing the packaging in this embodiment, as shown in Figure 8b, the continuous direction of the double-sided tape 5 on the right side of the perforations 12 (=cardboard backing 1 side) is aligned with the longitudinal direction of the elongated film packaging 2, and the shrink film 4 on the back side of the film packaging 2 is attached to the double-sided tape 5 to bond the film packaging 2 to the cardboard backing 1. Next, as shown in Figure 8c, the cardboard backing 1 is folded inwards at the perforation 12 to create a 90° bend at the fold portion 7, and the double-sided tape 5 attached to the fold portion 7 is then attached to the left side of the film packaging 2. To remove the packaged item 3 from this packaging, for example, the upper part of the fold portion 7 is pinched with the fingers and the fold portion 7 is separated from the perforation 12. As the fold portion 7 is gradually separated downwards from the top, the shrink film 4, along with the double-sided tape 5 attached to the fold portion 7, is pulled to the left in the plan view of Figure 7. A weak point is provided at the upper end of the shrink film 4 attached to this fold portion 7, and the shrink film 4 begins to tear from this point. Furthermore, when the folded portion 7 is separated from the backing paper 1, the part of the shrink film 4 that is attached to the double-sided tape 5 of the folded portion 7 is torn and separated from the surrounding part along the double-sided tape 5, and the part of the packaged item 3 on the folded portion 7 side is exposed from the shrink film 4 (the bag-like part). Once the part of the packaged item 3 on the folded portion 7 side is exposed in this way, the packaged item 3 is removed from the part of the shrink film 4 that is covering it in a bag-like manner.

[0026] In this embodiment, when a package is formed by attaching a shrink film 4 covering the packaged item 3 to a backing sheet 1, the backing sheet 1 is folded to form a folded portion 7, and the shrink film 4 is attached to the backing sheet 1 at two or more locations, including the folded portion 7, so that the edge (lower edge) of the backing sheet 1 at the folded portion 7 functions as a self-supporting portion 8. As a result, the package can stand on its own without the packaged item 3 or the shrink film 4 covering it touching the surface it is placed on.

[0027] Furthermore, by forming a self-standing function section 8 with the edge of the cardboard 1 at the right-angled folded section 7 and the edge of the cardboard 1 outside the folded section 7, it becomes possible to make the package stand upright stably.

[0028] Although the packaging according to the embodiment has been described above, the present invention is not limited to the configuration described in the above embodiment, and various modifications are possible within the scope of the gist of the present invention. For example, in the above embodiment, double-sided tape 5 is attached to the backing paper 1 along the longitudinal direction of the packaged item 3, and as a result, the shrink film 4 is configured to tear along the double-sided tape 5, that is, along the longitudinal direction of the packaged item 3. However, the direction in which the shrink film 4 is torn does not necessarily have to be along the longitudinal direction of the packaged item 3. However, it is easier to tear the shrink film 4 along the longitudinal direction of the packaged item 3 than to tear it in other directions. [Explanation of Symbols]
