Technical Field

[0001] The present invention relates to a packaging container that can easily package variously shaped packaged objects, not limited to rod-shaped or cylindrical shapes such as ballpoint pens, mechanical pencils, lipsticks, and stick-shaped adhesives, and is also suitable for display.

Background Art

[0002] Conventionally, a packaging container is known that is formed by assembling a blister dome made of a translucent synthetic resin and having a housing portion conforming to the shape of the packaged object and a mount (see, for example, Patent Document 1).

[0003] In the above packaging container, after the object to be packaged is stored in the housing portion of the blister dome, with one end as the leading end, the flat portion formed on the periphery of the blister dome is inserted into a pair of cut portions of the mount, and is inserted up to one end portion of the pair of cut portions. At this one end portion, the first retaining portion of the blister dome and the first retaining prevention portion of the mount are engaged, and at the same time, so that the two protruding portions provided at the other end portion of the blister dome do not come out from the other end portion of the pair of cut portions of the mount, the second retaining portion of the blister dome and the second retaining prevention portion of the mount are engaged.

[0004] In the above-mentioned packaging container, the blister dome is inserted into a pair of cut portions of the backing sheet, and at the front and rear ends of the flat portion, the engagement between the first retaining portion of the blister dome and the first retaining prevention portion of the backing sheet and the engagement between the second retaining portion of the blister dome and the second retaining prevention portion of the backing sheet prevent it from accidentally coming out. When a force is applied to the blister dome in the removal direction, the two bulging portions c of the first retaining portion of the blister dome are locked to the two cuts of the first retaining prevention portion of the backing sheet, and the two protrusions of the second retaining portion of the blister dome are engaged with the edges of the two branched cuts of the second retaining prevention portion of the backing sheet, and the blister dome is prevented from coming out of the pair of cut portions of the backing sheet. Therefore, it is said that the blister dome can be stably held on the backing sheet only by the operation of inserting the blister dome into the pair of cut portions of the backing sheet.

Mode for Carrying Out the Invention

[0013] Hereinafter, two embodiments of the present invention will be described with reference to the drawings. Note that the same reference numerals are given to the components common to each embodiment.

[0014] (First Embodiment) The first embodiment is shown in FIGS. 1 to 7. This packaging container 1 includes a blister dome 10 including a housing portion 11 that houses the object to be packaged P and flange portions 12 provided on both sides of the housing portion 11, and a mount 20 that holds the blister dome 10 with the housing portion 11 exposed to the outside via the flange portions 12. Hereinafter, each part will be described in detail.

[0015] The blister dome 10 is formed of a synthetic resin having translucency that is transparent or colored so that the object to be packaged P can be seen through from the outside. The back side of the housing portion 11 is an opening surface over the entire area, and the object to be packaged P is taken in and out through this opening surface. The housing portion 11 is formed in a dome shape conforming to the outer shape of the object to be packaged P. Although the flange portion 12 is provided around the housing portion 11 configured in this way, it is sufficient for the flange portion 12 to be on both sides of the housing portion 11 for fixing to the mount 20, and it is not particularly essential in other parts.

[0016] In addition, in this embodiment, although a sharp pencil is illustrated as the packaged object P, the packaged object P is not limited to examples of such writing instruments, and includes not only stick-shaped or cylindrical objects such as lipsticks and stick-shaped adhesives, but also various other shaped objects, and in addition to such regular-shaped objects, it also includes irregular-shaped objects typified by a small bag containing powder or liquid.

[0017] As shown in FIG. 1, the mount 20 includes a front plate 21 having a window portion 23 that exposes the accommodation portion 11 of the blister dome 10 to the outside, and a back plate 22 that closes the opening surface (not shown) of the accommodation portion 11 of the blister dome 10, and is formed by punching out, for example, from coated cardboard. The front plate 21 and the back plate 22 have the same outer shape and are connected in series via a fold line a at the side edges corresponding to the range where adhesive application regions 27, 27 described later are provided.

[0018] A window portion 23 is provided substantially at the center of the front plate 21, and a through hole 30 is formed at the base end portion. In addition, a sealing plate 24 is connected in series to the upper end of the front plate 21 via a fold line b. Further, a score line 28 is provided on the base end side of the front plate 21 so as to be orthogonal to the fold line a between the front plate 21 and the back plate 22. Adhesive application regions 27, 27 are set on both sides of the window portion 23 below the score line 28.

[0019] The window portion 23 only needs to have a size and shape that allows the accommodation portion 11 of the blister dome 10 to pass from the inside to the outside, and is not limited to the shape of the illustrated example.

[0020] The through hole 30 is for inserting the support rod of the display fixture when the present packaging container 1 is hung and displayed in the store, and is not limited to a circular shape as in the illustrated example and can be of any shape.

[0021] The scored line 28 is for facilitating the opening operation of the opening 29 (see Fig. 3) that allows the blister dome 10 to pass through to the window portion 23 between the front panel 21 and the back panel 22 on the proximal end side of the window portion 23. Therefore, the installation position of this scored line 28 depends on the height dimension of the accommodating portion 11 of the blister dome 10. If the height dimension is small, the scored line 28 is positioned closer to the sealing plate 24, and if it is large, it is positioned farther away from the sealing plate 24. Note that this scored line 28 is only for facilitating the opening operation of the opening 29 and may not be provided. If it is not provided, there is no risk of damaging the design of the front panel 21 during in-store display because no crease mark will be left on the front panel 21.

[0022] The sealing plate 24 is for sealing the proximal ends of the front panel 21 and the back panel 22 in a state where the blister dome 10 is completely arranged between the front panel 21 and the back panel 22. A through hole 31 corresponding to the through hole 30 of the front panel 21 is formed in this sealing plate 24 near the fold b. Also, a fold c extending in the width direction and a perforation d for cutting are superposed and formed in the middle. Further, a locking portion 25 having hook portions 26, 26 on both side portions is provided at the tip end portion.

[0023] The adhesive application areas 27, 27 are set parallel to the longitudinal direction of the front panel 21 at positions away from the window portion 23. The separation distance between the adhesive application areas 27, 27 and the window portion 23 is set to be slightly larger than the width dimension of the flange portions 12 located on both sides of the accommodating portion 11 of the blister dome 10, and it is designed so that the flange portions 12 can be inserted into the gap between the adhesive application areas 27, 27 and the window portion 23. Further, the length of the adhesive application areas 27, 27 is determined according to the size of the opening 29 formed between the front panel 21 and the back panel 22 at the proximal end side of the window portion 23, which allows the accommodating portion 11 to pass through the window portion 23. That is, if the height of the accommodating portion 11 is low, it is long, and if it is high, it is short. Specifically, the distance between the proximal end of the adhesive application areas 27, 27 and the fold line 28 is short if the height of the accommodating portion 11 is low, and long if it is high. In the illustrated example, the adhesive application areas 27, 27 are provided in a continuous band shape, but it is not limited to this, and it may be a band shape including a discontinuous portion in the middle, or a straight line connecting a large number of dots.

[0024] The back panel 22 has through holes 32 formed at the proximal end portion corresponding to the through holes 30, 31 of the front panel 21 and the sealing plate 24. Between the through hole 32 and the level corresponding to the fold line 28 of the front panel 21, an insertion hole 41 and a zipper portion 40 are arranged side by side in the vertical direction on the paper surface. And from the cut 42 at the upper end edge of these insertion holes 41 and the zipper portion 40, the locking portion 25 of the sealing plate 24 can be inserted into the gap between the front panel 21 and the back panel 22. Further, in a state where the locking portion 25 of the sealing plate 24 is inserted into the gap between the front panel 21 and the back panel 22, the hook portions 26, 26 of the locking portion 25 Cut 42 are engaged with. Also, below the zipper portion 40, another adhesive application area 27, 27 is set at a position corresponding to the adhesive application areas 27, 27 of the front panel 21.

[0025] In the packaging container 1 having the above configuration, the sealing plate 24, the locking portion 25, the hook portions 26 、 the insertion hole 41 and the cut 42 correspond to the engaging means in the present invention.

[0026] Next, the packaging procedure using the packaging container 1 with the above configuration will be described.

[0027] First, an adhesive (not shown) is applied to either one or both of the adhesive application areas 27, 27 of the front panel 21 or the adhesive application areas 27, 27 of the back panel 22. Then, as indicated by the arrow in FIG. 1, the fold line a between the front panel 21 and the back panel 22 is valley-folded, and the front panel 21 is superimposed on the back panel 22 and the two are adhered. The state after this adhesion is completed is shown in FIG. 2.

[0028] Next, as shown in FIG. 3, with the base end side of the front panel 21 lifted and opened, and an opening 29 secured between the base end of the back panel 22, a blister dome 10 in which the object to be packaged P has been previously accommodated in the accommodation part 11 is inserted into the opening 29 from its tip side. Here, if a folding line 28 is provided on the front panel 21, the opening operation of the opening 29 becomes easier. When further inserted, the flange parts 12 on both sides of the accommodation part 11 of the blister dome 10 slide into the gap between the window part 23 of the front panel 21 and the adhesive application areas 27, 27. Then, the blister dome 10 is pushed between the front panel 21 and the back panel 22 until the tip of the accommodation part 11 of the blister dome 10 abuts against the tip of the window part 23. This state is shown in FIG. 4.

[0029] When the insertion operation of the blister dome 10 is completed as described above, the fold line b at the boundary between the front panel 21 and the sealing plate 24 is mountain-folded, and the sealing plate 24 is turned behind the back panel 22. As shown in FIG. 5, after the fold line c of the sealing plate 24 is mountain-folded, the locking part 25 is inserted into the gap between the front panel 21 and the back panel 22 from the cut 42 at the upper edge of the zipper part 40. Then, the locking part 25 is pushed in until the engagement between the hook parts 26, 26 of the locking part 25 and the zipper part of the zipper part 40 is completed, and thus the packaging operation is completed. This state is shown in FIGS. 6 and 7.

[0030] To take out the packaged object P thus packaged, the locking portion 25 is broken from the perforation d of the sealing plate 24 and pulled up, and then the zipper portion 40 engaged with the hook portions 26, 26 is torn off to open it. After that, the base end side of the sealing plate 24 and the front plate 21 is lifted to open, and the blister dome 10 is pulled out from the opening 29 (see FIG. 3) that opens between the base end of the back plate 22 in the reverse direction of the packaging procedure. Finally, the packaged object P may be taken out from the opening surface of the accommodating portion 11 of the blister dome 10.

[0031] (Second Embodiment) The second embodiment of the present invention will be described with reference to FIGS. 8 to 18. The packaged object P in this embodiment is a ballpoint pen thicker than the mechanical pencil exemplified in the first embodiment, and is accommodated such that the position of the pen tip is opposite to that in the first embodiment. In addition, since this embodiment is mainly different from the first embodiment only in the configurations of the window portion 23, the sealing plate 24, the locking portion 25, the back plate 22, and the zipper portion 40, the differences will be mainly described below.

[0032] A first sealing plate 241 is continuously provided at the base end portion of the front plate 21 via a fold e. Two folds f and g are provided along the width direction of the first sealing plate 241 in the vertical direction of the paper surface. At the fold g closest to the base end, a main locking piece 243 is provided at the center, and sub-perforations 244, 244 are provided on both sides of the main locking piece 243, respectively.

[0033] The window portion 23 is formed to have a length such that its proximal end reaches the fold f located at the center of the first sealing plate 241. Further, a protective piece 231 is continuously provided at the proximal end of the window portion 23 via the fold f. In this embodiment, since the article P is accommodated with the pen tip facing the first sealing plate 241, when an impact such as a drop is applied in the direction of the pen tip, the protective piece 231 is for protecting the first sealing plate 241 so that the pen tip does not pierce through the first sealing plate 241. Note that when the pen tip does not face the first sealing plate 241 as in the first embodiment, or in the case of an article other than the writing instrument as described above and the article P is such that the portion facing the first sealing plate 241 is not sharp, if there is no risk of the first sealing plate 241 being damaged by the article P due to an impact, this protective piece 231 may not be provided.

[0034] The back plate 22 is provided with a zipper portion 40 extending from its distal end toward the proximal end. Further, a second sealing plate 242 is continuously provided at the proximal end of the back plate 22 via a fold h. A pair of sub-locking pieces 245, 245 project from the proximal edge of the second sealing plate 242 so as to correspond to the sub-cutouts 244, 244 of the first sealing plate 241. Further, a mountain-shaped main cutout 246 is formed at a position on the back plate 22 on the distal end side of the through hole 32 so as to correspond to the main locking piece 243 of the first sealing plate 241.

[0035] In the packaging container 1 having the above-described configuration, the first sealing plate 241, the second sealing plate 242, the main locking piece 243, the sub-cutouts 244, the sub-locking pieces 245, and the main cutout 246 correspond to the engaging means in the present invention.

[0036] Next, the packaging procedure using the packaging container 1 having the above-described configuration will be described.

[0037] First, an adhesive (not shown) is applied to either one or both of the adhesive application areas 27, 27 of the front plate 21 or the adhesive application areas 27, 27 of the back plate 22, and then, as indicated by the arrow in FIG. 8, the fold a between the front plate 21 and the back plate 22 is valley-folded and the front plate 21 is superimposed on the back plate 22 and the two are adhered. The state in which this adhesion is completed is shown in FIG. 9.

[0038] Next, as shown in FIG. 10, the fold e between the front panel 21 and the first sealing plate 241 is valley-folded, and the first sealing plate 241 is lifted from the back panel 22 to secure the opening 29. Also, the protective piece 231 is folded in by mountain-folding the fold f of that portion on the back side of the first sealing plate 241.

[0039] Subsequently, as shown in FIG. 11, the blister dome 10 in which the packaged item P has been previously housed in the housing portion 11 is inserted into the opening 29 from its tip side. When further inserted, the flange portions 12 on both sides of the housing portion 11 of the blister dome 10 slide into the gap between the window portion 23 of the front panel 21 and the adhesive application regions 27, 27. Thereafter, the blister dome 10 is pushed between the front panel 21 and the back panel 22 until the tip portion of the housing portion 11 of the blister dome 10 abuts against the tip portion of the window portion 23. This state is shown in FIG. 12.

[0040] Next, as shown in FIGS. 13 to 15, the fold f of the first sealing plate 241 is mountain-folded and the fold g is valley-folded, the main locking piece 243 of the first sealing plate 241 is lifted from the first sealing plate 241 to its back side, and the main locking piece 243 is inserted into the main cut 246 of the back panel 22 and locked. In this state, the protective piece 231 will be interposed between the back surface of the first sealing plate 241 and the blister dome 10, and as described above, there is no risk that the first sealing plate 241 will be damaged by the packaged item P due to an impact such as a drop.

[0041] Subsequently, as shown in FIG. 16, the fold h between the back panel 22 and the second sealing plate 242 is valley-folded to turn the second sealing plate 242 to the front of the first sealing plate 241, and finally, as shown in FIG. 17, the second sealing plate 242 is overlapped on the first sealing plate 241 and the sub-locking pieces 245, 245 of the second sealing plate 242 are inserted into the sub-cuts 244, 244 of the first sealing plate 241 and locked, thus completing the packaging operation. This state is shown in FIG. 18.

[0042] To take out the packaged object P thus packaged, the leading edges of the front panel 21 and the back panel 22 are forcibly opened, and the tip of the zipper portion 40 is grasped and the zipper portion 40 is torn off toward the base end side of the back panel 22, so that the opening surface of the accommodating portion 11 of the blister dome 10 is exposed. Then, the object P can be taken out from there.

[0043] (Other embodiments) It should be noted that the embodiments disclosed this time are illustrative in all respects and are not a basis for restrictive interpretation. For example, as shown in Fig. 19, the configuration of the zipper part 40 in the first embodiment may be the same as the configuration of the zipper part in the second embodiment. That is, the zipper part 40 may be provided on the back panel 22 so as to face the opening surface of the housing part 11 of the blister dome 10 from the tip to the base end between the adhesive application regions 27, 27. The technical scope of the present invention is not interpreted only by the above-described embodiments, but is defined based on the description in the claims. Further, the technical scope of the present invention includes all changes within the meaning and scope equivalent to the claims.
