Description

Technical Field

[0001] The present invention relates to a packaging container that can easily package various shaped packaged items, not limited to rod-shaped or cylindrical ones such as ballpoint pens, mechanical pencils, lipsticks, and stick-like 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 adapted to the shape of the packaged item, and a mount (see, for example, Patent Document 1).

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

[0004] In the above-described packaging container, the blister dome is inserted into a pair of notches in the cardboard backing, and is prevented from coming out unintentionally by the engagement of the first retaining portion of the blister dome with the first retaining portion of the cardboard backing and the engagement of the second retaining portion of the blister dome with the second retaining portion of the cardboard backing at the front and rear ends of the flat portion. Furthermore, when a force is applied to the blister dome in the direction of removal, the two bulges c of the first retaining portion of the blister dome are locked into the two notches of the first retaining portion of the cardboard backing, and the two projections of the second retaining portion of the blister dome engage with the edges of the two branch-shaped notches of the second retaining portion of the cardboard backing, thereby preventing the blister dome from coming out of the pair of notches in the cardboard backing. Therefore, it is possible to stably hold the blister dome in place on the cardboard backing simply by inserting it into the pair of notches in the cardboard backing. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2005-29244 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] However, the packaging container described in Patent Document 1 is said to be able to hold the blister dome to the cardboard backing simply by inserting the blister dome into a pair of notches in the cardboard backing, but this has the following problems. Specifically, in order to prevent the blister dome containing the packaged item from coming out of the cardboard backing, the cardboard backing must have a pair of notches and anti-slip parts formed at both ends of the notches, and correspondingly, anti-slip parts must also be formed at both ends of the blister dome. For this reason, both the blister dome and the cardboard backing must undergo many molding processes, and since this requires high processing precision, the processing process becomes complicated and the processing cost increases. In addition, the anti-slip parts of the blister dome and the anti-slip parts of the cardboard backing must be engaged at both ends. For this reason, the assembly of the blister dome to the cardboard backing is complicated.

[0007] The present invention has been made in view of the above, and its objective is to provide a packaging container that eliminates the need for many of the processes required for conventional packaging containers in both the blister dome and the cardboard backing, allows for easy molding of both, and enables extremely simple assembly of the blister dome onto the cardboard backing while securely holding the blister dome to the cardboard backing. [Means for solving the problem]

[0008] To achieve the above objective, the present invention has the following configuration.

[0009] The packaging container according to the present invention comprises a blister dome including a housing portion for housing an object to be packaged, flange portions provided on at least both sides of the housing portion, and a backing that holds the blister dome via the flange portions with the housing portion exposed to the outside. The backing comprises a front plate having a window portion that exposes the housing portion of the blister dome to the outside, and a back plate that closes the opening surface of the housing portion of the blister dome. The front plate and the back plate are bonded together on both sides of the window portion such that a gap is secured on at least both sides of the window portion to allow the insertion of the flange portions, and an opening is secured between the front plate and the back plate on the base end side of the window portion to allow the housing portion to pass through the window portion, and engaging means are provided to engage the respective base ends of the front plate and the back plate.

[0010] In the above-mentioned packaging container, a fold line may be provided on the base end side of the front panel to facilitate the opening operation. [Effects of the Invention]

[0011] According to the present invention, many of the processes required for conventional packaging containers are unnecessary for both the blister dome and the cardboard backing, both of which are easy to mold, and the assembly of the blister dome onto the cardboard backing is extremely simple, while the blister dome can be securely held to the cardboard backing.

Mode for Carrying Out the Invention

[0013] Hereinafter, two embodiments of the present invention will be described with reference to the drawings. In addition, the same reference numerals are assigned to the constituent elements common to each embodiment.

[0014] (First Embodiment) The first embodiment is shown in Figures 1 to 7. As shown in Figure 3, this packaging container 1 comprises a blister dome 10 including a housing section 11 for housing the packaged item P, flange sections 12 provided on both sides of the housing section 11, and a backing 20 that holds the blister dome 10 via the flange sections 12 when the housing section 11 is exposed to the outside. Each part will be described in detail below.

[0015] The blister dome 10 is molded from a transparent or colored translucent synthetic resin so that the packaged item P can be seen from the outside. The entire back side of the storage section 11 is an open surface, and the packaged item P is inserted and removed from this opening. The storage section 11 is formed in a dome shape that conforms to the outer shape of the packaged item P. A flange portion 12 is provided around the storage section 11, but for fixing to the backing card 20, the flange portion 12 is only necessary on both sides of the storage section 11 and is not particularly essential in other parts.

[0016] In this embodiment, a mechanical pencil is shown as the packaged item P, but the packaged item P is not limited to such writing instruments, and includes not only rod-shaped or cylindrical items such as lipstick and glue sticks, but also various other shapes, as well as irregularly shaped items such as small pouches containing powders or liquids.

[0017] As shown in Figure 1, the cardboard backing 20 comprises a front panel 21 having a window 23 that exposes the housing section 11 of the blister dome 10 to the outside, and a back panel 22 that closes the opening (not shown) of the housing section 11 of the blister dome 10, and is die-cut from, for example, coated cardboard. The front panel 21 and the back panel 22 have the same external shape and are connected to each other via folds a at their side edges, corresponding to the areas where the adhesive application areas 27, 27 described later are provided.

[0018] A window 23 is provided approximately in the center of the front panel 21, and a through hole 30 is formed at the base end. A sealing plate 24 is attached to the upper end of the front panel 21 via a fold b. Furthermore, a fold line 28 is provided on the base end side of the front panel 21 so as to be perpendicular to the fold a between the front panel 21 and the back panel 22. Adhesive application areas 27, 27 are set on both sides of the window 23 below the fold line 28.

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

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

[0021] The fold line 28 is intended to facilitate the opening operation of the opening 29 (see Figure 3) between the front panel 21 and the back panel 22 at the base end of the window section 23, which allows passage through the window section 23 of the blister dome 10. Therefore, the position of this fold line 28 depends on the height dimension of the housing section 11 of the blister dome 10; if the height dimension is small, the fold line 28 will be located closer to the sealing plate 24, and if it is large, it will be located further away from the sealing plate 24. Note that this fold line 28 is merely for facilitating the opening operation of the opening 29 and does not need to be provided. If it is not provided, there will be no fold marks on the front panel 21, so there is no risk of damaging the design of the front panel 21 when displayed in stores.

[0022] The sealing plate 24 is used to seal the base ends of the front plate 21 and the back plate 22 after the blister dome 10 has been placed between the front plate 21 and the back plate 22. The sealing plate 24 has a through hole 31 near the fold b that corresponds to the through hole 30 of the front plate 21. In addition, a fold c extending in the width direction and a perforation d for cutting are superimposed in the middle. Furthermore, the tip is provided with a locking portion 25 having hook portions 26, 26 on both sides.

[0023] The adhesive application areas 27, 27 are set parallel to the longitudinal direction of the front panel 21 at a position away from the window portion 23. The distance between these 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 housing portion 11 of the blister dome 10, so that the insertion of the flange portions 12 into the gap between the adhesive application areas 27, 27 and the window portion 23 is permitted. Furthermore, the length of these adhesive application areas 27, 27 is determined according to the size of the opening 29 that is formed between the front panel 21 and the back panel 22 at the base end side of the window portion 23, allowing the housing portion 11 to pass through the window portion 23. That is, if the housing portion 11 is low, the area is made longer, and if it is high, it is made shorter. Specifically, the distance between the base end of the adhesive application areas 27, 27 and the fold line 28 is made shorter if the housing portion 11 is low, and longer if it is high. In the illustrated example, the adhesive application areas 27, 27 are provided in a continuous strip shape, but this is not limited to this. They may also be strips with discontinuous sections, or a series of dots arranged in a straight line.

[0024] The back panel 22 has a through-hole 32 formed at its base end, corresponding to the through-holes 30 and 31 of the front panel 21 and the sealing panel 24. Between this 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. The locking portion 25 of the sealing panel 24 can be inserted into the gap between the front panel 21 and the back panel 22 through the cut 42 at the upper edge of the insertion hole 41 and the zipper portion 40. Furthermore, when the locking portion 25 of the sealing panel 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 engage with the zipper portion of the zipper portion 40. Below the zipper portion 40, another adhesive application area 27, 27 is set at a position corresponding to the adhesive application area 27, 27 of the front panel 21.

[0025] In the packaging container 1 with the above configuration, the sealing plate 24, locking portion 25, hook portion 26, zipper portion 40, insertion hole 41, and cut 42 correspond to the engagement means in the present invention.

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

[0027] First, adhesive (not shown) is applied to either the adhesive application areas 27,27 of the front panel 21 or the adhesive application areas 27,27 of the back panel 22, or both. Then, as indicated by the arrows in Figure 1, the fold a between the front panel 21 and the back panel 22 is folded inwards, and the front panel 21 is placed on top of the back panel 22 to bond them together. Figure 2 shows the state after this bonding is completed.

[0028] Next, as shown in Figure 3, the base end of the front panel 21 is lifted to open it, and with an opening 29 secured between it and the base end of the back panel 22, the blister dome 10, which has already contained the packaged item P in its storage section 11, is inserted into the opening 29 from its front end. Here, if the front panel 21 has a fold line 28, it becomes easier to open this opening 29. As it is inserted further, the flange portions 12 on both sides of the storage section 11 of the blister dome 10 slide into the gap between the window portion 23 of the front panel 21 and the adhesive application areas 27, 27. After that, the blister dome 10 is pushed between the front panel 21 and the back panel 22 until the front end of the storage section 11 of the blister dome 10 abuts against the front end of the window portion 23. This state is shown in Figure 4.

[0029] Once the insertion of the blister dome 10 is completed as described above, the fold b at the boundary between the front plate 21 and the sealing plate 24 is folded in a mountain fold to bring the sealing plate 24 behind the back plate 22. As shown in Figure 5, the fold c of the sealing plate 24 is folded in a mountain fold, and the locking portion 25 is inserted into the gap between the front plate 21 and the back plate 22 through the cut 42 at the upper edge of the zipper portion 40. Then, the locking portion 25 is pushed in until the hook portions 26, 26 of the locking portion 25 engage with the zipper portion of the zipper portion 40, and the packaging process is completed. This state is shown in Figures 6 and 7.

[0030] To remove the packaged item P in this manner, the locking portion 25 is broken along the perforations d of the sealing plate 24 and pulled up, and the zipper portion 40, which is engaged with the hooks 26, 26, is torn off. After that, the sealing plate 24 and the base end of the front plate 21 are lifted to open them, and the blister dome 10 is pulled out in the opposite direction to the packaging procedure from the opening 29 (see Figure 3) that opens between the base end of the back plate 22 and the front plate 24. Finally, the packaged item P is removed from the opening of the housing portion 11 of the blister dome 10.

[0031] (Second Embodiment) A second embodiment of the present invention will be described with reference to Figures 8 to 18. In this embodiment, the packaged item P is a ballpoint pen that is thicker than the mechanical pencil exemplified in the first embodiment, and the position of the pen tip is reversed compared to the first embodiment. This embodiment differs from the first embodiment mainly in the configuration of the window portion 23, sealing plate 24, locking portion 25, back plate 22, and zipper portion 40, so the following description will focus on these differences.

[0032] A first sealing plate 241 is attached to the base end of the front plate 21 via a fold e. Two folds f and g are provided on the first sealing plate 241 along the width direction of the first sealing plate 241, aligned in the vertical direction of the paper surface. A main locking piece 243 is provided in the center of the fold g closest to the base end, and secondary cuts 244, 244 are provided on both sides of this main locking piece 243.

[0033] The window portion 23 is formed to a length that reaches the fold f located in the center of the first sealing plate 241. A protective piece 231 is attached to the base end of the window portion 23 via the fold f. In this embodiment, the protected piece 231 is intended to protect the first sealing plate 241 from being pierced by the pen tip when an impact such as a drop is applied in the direction of the pen tip, since the packaged item P is contained with the pen tip facing the first sealing plate 241. However, if the pen tip is not facing the first sealing plate 241 as in the first embodiment, or if the packaged item is an article other than a writing instrument and the part facing the first sealing plate 241 is not sharp, and there is no risk of the first sealing plate 241 being damaged by the packaged item P due to impact, then this protective piece 231 does not need to be provided.

[0034] The back plate 22 has a zipper portion 40 extending from its tip to its base. A second sealing plate 242 is attached to the base end of the back plate 22 via a fold h. A pair of sub-locking pieces 245, 245 are provided projecting from the base edge of the second sealing plate 242 so as to correspond to the sub-cuts 244, 244 of the first sealing plate 241. In addition, a V-shaped main cut 246 is formed in the back plate 22 at a position on the tip 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 with the above configuration, the first sealing plate 241, the second sealing plate 242, the main locking piece 243, the secondary cut 244, the secondary locking piece 245, and the main cut 246 correspond to the engaging means in the present invention.

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

[0037] First, adhesive (not shown) is applied to either the adhesive application areas 27,27 of the front panel 21 or the adhesive application areas 27,27 of the back panel 22, or both. Then, as indicated by the arrows in Figure 8, the fold a between the front panel 21 and the back panel 22 is folded inwards, and the front panel 21 is placed on top of the back panel 22 to bond them together. Figure 9 shows the state after this bonding is completed.

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

[0039] Next, as shown in Figure 11, the blister dome 10, which already contains the packaged product P in its containment section 11, is inserted into the opening 29 from its front end. As it is inserted further, the flanges 12 on both sides of the containment section 11 of the blister dome 10 slide into the gap between the window section 23 of the front plate 21 and the adhesive application areas 27, 27. After that, the blister dome 10 is pushed between the front plate 21 and the back plate 22 until the front end of the containment section 11 of the blister dome 10 abuts against the front end of the window section 23. This state is shown in Figure 12.

[0040] Next, as shown in Figures 13 to 15, the fold f of the first sealing plate 241 is folded in a mountain fold and the fold g is folded in a valley fold, the main locking piece 243 of the first sealing plate 241 is lifted away 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 plate 22 and locked in place. In this state, the protective piece 231 is interposed between the back side of the first sealing plate 241 and the blister dome 10, and as described above, there is no risk of the first sealing plate 241 being damaged by the packaged product P due to impact such as dropping.

[0041] Next, as shown in Figure 16, the fold line h between the back plate 22 and the second sealing plate 242 is valley-folded to bring the second sealing plate 242 to the front of the first sealing plate 241. Finally, as shown in Figure 17, the second sealing plate 242 is placed on top of the first sealing plate 241, and the auxiliary locking pieces 245, 245 of the second sealing plate 242 are inserted into the auxiliary cuts 244, 244 of the first sealing plate 241 to lock them in place, thus completing the packaging process. This state is shown in Figure 18.

[0042] To remove the packaged item P in this manner, 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 pulled towards the base end of the back panel 22, thereby exposing the opening of the storage portion 11 of the blister dome 10, from which the packaged item P can be removed.

[0043] (Other embodiments) The embodiments disclosed herein are illustrative in all respects and do not constitute a limiting interpretation. Therefore, the technical scope of the present invention is not construed solely by the embodiments described above, but is defined based on the claims. Furthermore, the technical scope of the present invention includes all modifications within the meaning and scope of equivalence to the claims. [Explanation of Symbols]
