[0019] First, the basic structure of the packaging mount according to the present invention will be described by taking one of a plurality of embodiments as an example, and then each embodiment will be described.

[0020] <Basic composition of packaging paper> This packaging backing 1 can easily package cylindrical or rod-shaped products such as lipstick or stick-shaped glue as shown in Figures 1 to 3, flat, gusset-free sample bags containing small amounts of fluid or powder, and even ampoules containing liquid medicine, and can also be used for display purposes if necessary.

[0021] That is, the packaged item P as described above is packaged with a front panel 20 having a window portion 10 that partially exposes the packaged item P, and a back panel 30 that is provided in series with the front panel 20.

[0022] The window portion 10 has both end portions 10T, 10B or one end portion 10T serving as a holding portion 13 that holds the packaged item P, while both side edges 10L, 10R serve as regulating portions 14 that regulate the lateral movement of the packaged item P.

[0023] The front plate 20 has two side edges 20L and 20R. In the center of An engaging fold 40 is formed. At both ends of this engaging fold 40, engaging pieces 50, 50 are provided which protrude towards the back panel 30 when the engaging fold 40 is valley folded.

[0024] The rear plate 30 is provided with engagement portions 60, 60 at both side edges 30L, 30R at positions facing the engagement pieces 50, 50 of the front plate 20, into which the engagement pieces 50, 50 are inserted in a protruding state to engage.

[0025] Then, the engagement pieces 50, 50 of the front plate 20 engage with the engagement portions 60, 60 of the rear plate 30, whereby the front plate 20 and the rear plate 30 are integrated together and the packaged item P is fixed within the window portion 10.

[0026] According to the packaging mount 1 described above, the packaged item P is held within the window 10, and the front panel 20 and the back panel 30 are integrated in an overlapping state by engaging the engaging pieces 50, 50 with the engaging parts 60, 60, so unlike conventional packaging mounts of this type, there is no need for a shrink film to fix the packaged item to the mount, or an adhesive to integrate the front panel and back panel of the mount. This makes it possible to reduce material costs and simplify the packaging work, and also allows the packaged item to be firmly fixed and packaged, and can also be displayed.

[0027] Hereinafter, a number of embodiments of the above-mentioned packaging line 1 will be described with reference to the drawings. Note that the same components in the above description and among the embodiments are denoted by the same reference numerals.

[0028] [First embodiment] <Composition of packaging paper> A first embodiment of a packaging mount according to the present invention will be described with reference to FIGS.

[0029] In this embodiment, the front panel 20 includes a front panel 21 in which the window portion 10 is formed, a top panel 22 arranged on one end side of the front panel 21, a hanging plate 23 arranged on one end side of the top panel 22, and a locking plate 24 arranged on one end side of the hanging plate 23. At each boundary between the front panel 21, the top panel 22, the hanging plate 23, and the locking plate 24, folds a, b, and c are formed.

[0030] The dimension between both ends of the front panel 21 is set to be slightly longer than the length of the packaged item P. A first engagement fold 40F is provided approximately in the center between both ends of the front panel 21.

[0031] The window 10 is an elongated hole that is slightly shorter than the length of the packaged item P. The distance between the side edges 10L, 10R is the same as or slightly wider than the width of the packaged item P. Because the window 10 is configured in this way, when the first engagement fold 40F is folded in a valley, both ends of the window 10 become holding portions 13, 13 that hold the exposed surface side of the packaged item P. Furthermore, the side edges 10L, 10R of the window 10 become restricting portions 14, 14 that restrict the lateral movement of the packaged item P.

[0032] The shape and size of the window portion 10 are not limited to those shown above and in the drawings, but are determined appropriately depending on the shape and size of the item P to be packaged.

[0033] The dimension between both ends of the top plate 22 is slightly larger than the thickness of the packaged item P (if the packaged item is cylindrical or rod-shaped, this refers to its diameter).

[0034] The hanging plate 23 is connected to one end of the top plate 22 via a second engagement fold 40S, and is used when the packaged items P are hung on hooks for display and sale at a store such as a mass retailer or convenience store. For this reason, a first hook insertion hole 23H is formed near one end.

[0035] The lock plate 24 has an anchor 24A formed at one end thereof. Also, a second hook insertion hole 24H overlapping with the first hook insertion hole 23H of the hanging plate 23 is formed. Furthermore, a fold d is formed between the anchor 24A and the second hook insertion hole 24H. The lock plate 24 thus formed is folded back toward the lock receiving plate 36 of the back plate 30 via the fold c on the hanging plate 23 side, and the anchor 24A is inserted into the anchor insertion portion 36R of the lock receiving plate 36, thereby fixing the lock receiving plate 36 in a state overlapping with the lock receiving plate 36. Also, at this time, the second hook insertion hole 24H overlaps with the first hook insertion hole 23H of the hanging plate 23, and one hook insertion hole 27 is formed. Here, a fold d is formed between the anchor 24A and the second hook insertion hole 24H, and by folding this fold d slightly inwardly, it becomes easier to insert the anchor 24A into the anchor insertion portion 36R (described later).

[0036] The rear panel 30 includes a bottom panel 31 connected to the other end side of the front panel 21 via a fold e, a back panel 32 connected to the bottom panel 31 via a fold f and facing the front panel 21, and a lock receiving plate 36 arranged on one end side of the back panel 32, overlapping with the hanging plate 23 of the front panel 20 and receiving the lock plate 24.

[0037] The dimension between both ends of the bottom plate 31 is set to be the same as the dimension between both ends of the top plate 22. In this embodiment, the bottom surface of the packaged item P is in contact with the inner surface of the bottom plate 31, but this is not limited to the embodiment, and there may be a gap between the inner surface of the bottom plate 31 and the bottom surface of the packaged item P.

[0038] The back plate 32 has an area substantially equal to the projected area of ​​the front plate 21 in a state in which the first engagement fold 40F is valley folded and the first engagement fold 40F is in contact with the surface of the back plate 32. The back plate 32 has an opening 32W that partially allows the back side of the packaged item P to be exposed, facing the window 10 of the front plate 21. In this embodiment, the size of the opening 32W is such that the length is substantially equal to the length of the packaged item P, and the width is shorter than the diameter of the packaged item P. When the packaged item P is cylindrical or rod-shaped, the opening 32W can be provided to fix the packaged item P more firmly by the packaging mount 1 in cooperation with the window 10. The shape of the opening 32W may be appropriately determined according to the shape and size of the packaged item P. The opening 32W is not necessarily required to be provided.

[0039] The lock receiving plate 36 is extended from one end of the back plate 32. An arc-shaped notch 36N is formed at one end of the lock receiving plate 36 so as not to hinder the overlapping of the first hook insertion hole 23H of the hanging plate 23 and the second hook insertion hole 24H of the lock plate 24. An anchor insertion portion 36R is formed so that the anchor 24A of the lock plate 24 is inserted and engaged therewith. The anchor insertion portion 36R is composed of a pair of zipper lines 36Z formed in parallel with both side edges of the lock plate 24, slits 36S, 36S formed from one end of each of the zipper lines 36Z in a direction facing each other, and a finger hole 36H formed continuously from the slits 36S, 36S so as to face the notch 36N. The shape of the anchor insertion portion 36R is not limited to this.

[0040] As described above, the first engagement fold 40F is provided at the approximate center between both ends of the front panel 21, and the second engagement fold 40S, which is the fold b, is provided at the boundary between the top panel 22 and the hanging panel 23. The first engagement pieces 50F, 50F are provided at both ends of the first engagement fold 40F, and the second engagement pieces 50S, 50S are provided at both ends of the second engagement fold 40S. These first engagement pieces 50F, 50F and second engagement pieces 50S, 50S are formed so as to be able to protrude toward the back panel 32 when the first engagement fold 40F and the second engagement fold 40S are folded in a valley (folded in a direction in which the first and second engagement folds 40F, 40S protrude toward the back panel 32). Specifically, the first engagement pieces 50F, 50F and the second engagement pieces 50S, 50S are formed by bending both ends of the first engagement fold 40F and both ends of the second engagement fold 40S so that they are biased toward the bottom plate 31, and forming the bent areas into cuts 50C.

[0041] The above-mentioned back plate 32 is provided on both side edges thereof with first engagement portions 60F, 60F into which the first engagement pieces 50F, 50F provided on the front plate 21 are inserted in a protruding state and engage with, and second engagement portions 60S, 60S into which the second engagement pieces 50S, 50S provided on the boundary between the top plate 22 and the hanging plate 23 are inserted in a protruding state and engage with. These first engagement portions 60F, 60F and second engagement portions 60S, 60S are respectively composed of horizontal cuts 60H made from both side edges of the back plate 32 toward the inside thereof, vertical cuts 60V extending from the depths of the horizontal cuts 60H toward the lock receiving plate 36 side, and weakening lines 60W formed parallel to the horizontal cuts 60H from the depths of the vertical cuts 60V toward the side edges of the back plate 32. The length of the horizontal notch 60H is set to be approximately equal to the width dimension of each of the engagement pieces 50, 50, and the length of the vertical notch 60V is set to be approximately equal to the protruding length of each of the engagement pieces 50, 50. Note that the configurations of the first engagement portions 60F, 60F and the second engagement portions 60S, 60S are not limited to the above example, and may be configured, for example, as notches formed by cutting out the portions surrounded by the horizontal notches 60H, vertical notches 60V, and weakening lines 60W.

[0042] Although the packaging backing 1 described above is composed of a single sheet of cardboard, other relatively rigid paper materials such as cardboard, paperboard, milk carton paper, corrugated cardboard, laminated paper, etc. may be used instead of cardboard. Also, composite materials in which such paper materials are laminated with a synthetic resin film, or synthetic resin sheets with excellent flexibility may be used.

[0043] <Packaging Procedure> Next, a procedure for packaging the packaged item P with the above-described packaging sheet 1 will be described. Note that in the drawings showing the packaging process, the packaged item P is omitted.

[0044] First, with the packaging sheet 1 unfolded, the packaged item P is partially fitted into the opening 32W of the back plate 32. At this time, the packaged item P is positioned relative to the back plate 32 by the opening 32W.

[0045] Next, the bottom plate 31 is raised from the fold f, and the fold e is mountain-folded so that the front plate 21 is above the back plate 32, and the first engagement fold 40F is valley-folded to fold the front plate 21 into a dogleg shape. As a result, the first engagement pieces 50F, 50F at both ends of the first engagement fold 40F protrude toward the back plate 32.

[0046] Next, the first engagement pieces 50F, 50F are inserted into the first engagement portions 60F, 60F, whereby the holding portion 13 on the other end portion 10B side of the window portion 10 holds the other end of the packaged item P (see FIG. 5).

[0047] 6, the fold a at the boundary between the front panel 21 and the top panel 22 is mountain-folded, and the second engagement fold 40S is valley-folded. As a result, the second engagement pieces 50S, 50S at both ends of the second engagement fold 40S protrude toward the back panel 32.

[0048] 7, the second engagement pieces 50S, 50S are inserted into the second engagement portions 60S, 60S, and then the hanging plate 23 is overlapped with the lock receiving plate 36. As a result, the holding portion 13 on the one end 10T side of the window portion 10 holds one end of the packaged item P, and the front plate 21 is integrated with the back plate 32, and the packaged item P is fixed between the front plate 21 and the back plate 32 (see FIGS. 7 to 9).

[0049] Finally, as shown in Fig. 10, the lock plate 24 is folded back toward the lock receiving plate 36 by mountain-folding the crease c, and the anchor 24A is inserted into the anchor insertion portion 36R (see Fig. 3). As a result, the front plate 20 and the back plate 30 are locked together in an integrated state.

[0050] The packaged item P thus packaged with the packaging backing 1 is displayed and exhibited by inserting a storefront display hook into the hook insertion hole 27 with a portion of the packaged item P exposed through the window portion 10, as shown in Figures 1 to 3.

[0051] [Modification of the first embodiment] A modified example of the first embodiment of the packaging mount according to the present invention will be described with reference to Figs.

[0052] This modification corresponds to a packaged article that is larger than the packaged article P in the first embodiment described above. Only the differences from the above embodiment will be described below.

[0053] In the first embodiment described above, the packaged item P corresponds to a relatively small and light item such as lipstick, lip balm, or stick-shaped glue, but in order to accommodate larger or heavier packaged items, it is necessary to take strength into consideration.

[0054] In this modification, a single reinforcing plate 33 is attached to the inner surfaces of the back plate 32 and the lock receiving plate 36 as shown in Fig. 11, and the three are integrated to improve the strength of the back plate 30. However, if the reinforcing plate 33 is simply attached, the thickness of the first engagement parts 60F, 60F and the second engagement parts 60S, 60S increases, making it difficult to insert the first engagement pieces 50F, 50F and the second engagement pieces 50S, 50S, and making it difficult for these engagement pieces 50, 50 to fit along the back surface of the back plate 32. In order to avoid this, in this modification, the first engagement parts 60F, 60F and the second engagement parts 60S, 60S of the back plate 32 are cut out (indicated by the reference symbol 60C in the figure), and the first engagement parts 60F, 60F and the second engagement parts 60S, 60S are formed only on the reinforcing plate 33. 13 to 15, the thickness of the first engagement portions 60F, 60F and the second engagement portions 60S, 60S is limited to the thickness of the reinforcing plate 33. As a result, when the first engagement pieces 50F, 50F and the second engagement pieces 50S, 50S are inserted, the portions surrounded by the horizontal notches 60H, the vertical notches 60V and the weakened lines 60W become easier to move, making it easier to insert the first engagement pieces 50F, 50F and the second engagement pieces 50S, 50S, and easier for these engagement pieces 50 to fit along the back surface of the back plate 32 after insertion.

[0055] The reinforcing plate 33 is formed with an opening 33W corresponding to the opening 32W of the back plate 32 and a notch 33N corresponding to the notch N of the lock receiving plate . The packaging procedure according to this modification is the same as that of the first embodiment described above, so a description thereof will be omitted.

[0056] [Second embodiment] <Composition of packaging paper> A second embodiment of the packaging mount according to the present invention will be described with reference to FIGS.

[0057] The differences between this embodiment and the first embodiment are: (1) the first engagement fold 40F is not formed in the front panel 21, and there is only one engagement fold; (2) there is no top panel 22, and the front panel 21 is directly connected to the hanging plate 23; (3) the engagement portion (corresponding to the second engagement portion 60S in the first embodiment) 60 is not composed of a horizontal notch 60H, a vertical notch 60V, and a weakening line 60W, and is formed by a cutout portion 60N obtained by cutting out the area surrounded by these three lines; (4) a zipper line 36Z is not formed in the lock receiving plate 36; and (5) in this embodiment, a pressure plate 25 is newly provided at one end of the window portion 10 to be clamped between the packaged item P and the back panel 32, and only the other end portion 10B of the window portion 10 is used as the retaining portion 13.

[0058] That is, in this embodiment, the front panel 20 includes a front panel 21 in which a window portion 10 is formed, a hanging plate 23 arranged on one end side of the front panel 21, and a locking plate 24 arranged on one end side of the hanging plate 23.

[0059] The back panel 30 includes a bottom panel 31 connected to the other end side of the front panel 21, a back panel 32 facing the front panel 21, and a lock receiving plate 36 arranged on one end side of the back panel 32, overlapping with the hanging plate 23 of the front panel 20 and receiving the lock plate 24.

[0060] The engagement crease 40 is provided only at the boundary between the front plate 21 and the hanging plate 23.

[0061] A pressing plate 25 is provided at one end of the window portion 10, which is sandwiched between the packaged item P and the back plate 32. This pressing plate 25 is formed by not cutting one end side of the punched piece when the window portion 10 is punched out.

[0062] <Packaging Procedure> Next, a procedure for packaging the packaged item P with the packaging sheet 1 as described above will be described.

[0063] First, as shown in Figures 20 and 21, the bottom plate 31 is raised from the fold f, and the fold e is mountain-folded so that the front plate 21 is above the back plate 32, while the engaging fold 40 is valley-folded to bend the front plate 21 and the hanging plate 23 into a dogleg shape. As a result, the engaging pieces 50, 50 at both ends of the engaging fold 40 protrude toward the back plate 32.

[0064] Next, the engagement pieces 50, 50 are inserted into the engagement portions 60, 60, and the hanging plate 23 is overlapped with the lock receiving plate 36, and then, as shown in Figures 22 and 23, the lock plate 24 is folded back toward the lock receiving plate 36 by mountain-folding the crease c, and the anchor 24A is inserted into the anchor insertion portion 36R. This causes the front plate 20 and the back plate 30 to be locked together in an integrated state.

[0065] Finally, the packaged item (not shown) is inserted into the window 10 from the hanging plate 23 toward the bottom plate 31, and the bottom of the packaged item is dropped onto the bottom plate 31. As a result, the lower end of the packaged item is held by the holding portion 13 on the other end 10B side of the window 10, and the pressing plate 25 is sandwiched between the packaged item and the back plate 32. This maintains the engagement between the engaging pieces 50, 50 and the engaging portions 60, 60, and there is no risk of the engaging pieces 50, 50 accidentally coming off the engaging portions 60, 60 even if the engaging portions 60 are the notches 60N as described above.

[0066] The packaged item thus packaged in the packaging mount 1 is displayed and exhibited by inserting a storefront display hook into the hook insertion hole 27 with a portion of the packaged item exposed through the window portion 10.

[0067] [Third embodiment] <Composition of packaging paper> A third embodiment of the packaging mount according to the present invention will be described with reference to FIGS.

[0068] In the first and second embodiments described above, a cylindrical or rod-shaped packaged item was the object of packaging. In this embodiment, however, the object of packaging is, for example, a flat, bag-shaped packaged item P without a gusset containing a small amount of fluid, powder, etc., as shown in FIG. 24.

[0069] In the packaging line 1 of this embodiment, the window 10 provided in the front panel 20 has a shape that generally matches the shape of the bulging storage portion PC in the packaged item P of the above-described form, as shown in Fig. 26, and is formed in a generally rectangular shape in the illustrated example. That is, the entire periphery of the window 10 serves as the holding portion 13 that holds the packaged item P.

[0070] The back panel 30 includes a back panel 32 facing the front panel 20, a cover panel 34 arranged on one end side of the back panel 32 and covering the front panel 20 in a folded state, and a locking claw 35 cut and raised from a fold i of the cover panel 34.

[0071] Here, the cover plate 34 is composed of a first cover plate 34F that directly contacts the upper surface of the front plate 20 and the storage portion PC of the packaged item P, and a second cover plate 34S that functions as an exterior when packaging is completed.

[0072] The front plate 20 is provided, between the other end thereof and the other end of the window portion 10, with a locking hole 26 into which a locking claw 35 is inserted.

[0073] The engagement fold 40 is provided at the center between both ends 10T, 10B of the window portion 10 or at a position from the center toward the other end B10B of the window portion 10, and engagement pieces 50,50 are formed at both ends of this engagement fold 40.

[0074] The engagement portions 60, 60 are provided at the opposite side edges 30L, 30R of the back plate 32 at positions facing the engagement folds 40, and their shape is similar to that of the second embodiment.

[0075] <Packaging Procedure> Next, a procedure for packaging the packaged item P with the above-described packaging sheet 1 will be described. Note that the packaged item P is not shown in the drawings referred to in the following description.

[0076] First, the packaged item P is placed on the back plate 32, and then the fold g at the boundary between the front plate 20 and the back plate 32 is mountain-folded, and the engagement fold 40 is valley-folded to bend the front plate 20 into a dogleg shape. As a result, the engagement pieces 50, 50 at both ends of the engagement fold 40 protrude toward the back plate 32.

[0077] Next, while aligning the edge of the window portion 10 with the edge of the storage portion PC of the packaged item P, the engaging pieces 50, 50 are inserted into the engaging portions 60, 60 as shown in Figure 27, and half of the area on the other end side of the front panel 20 is pressed against the back panel 32, and then half of the area on one end side of the front panel 20 is overlapped with the packaged item P as shown in Figure 28.

[0078] Next, as shown in Figures 28 and 29, the first cover plate 34F is mountain-folded at crease i to protrude the locking claws 35 outward, and then the crease h at the boundary between the back plate 32 and the second cover plate 34S is mountain-folded to overlap the first cover plate 34F with the storage portion PC of the packaged item P exposed from the window portion 10 and the front plate 20, and the locking claws 35 are inserted into the locking holes 26 of the front plate 20 to lock them together.

[0079] The packaged item P thus packaged with the packaging sheet 1 is shipped to the market with the container portion PC exposed from the window 10 covered with the folded first cover plate 34F and second cover plate 34S as shown in Fig. 25. Fig. 30 is a perspective view of the rear side showing the completed packaging state.

[0080] In this embodiment, the packaged item P is packaged in a state where it is completely covered by the cover plate 34 and the back plate 32, thereby preventing accidents such as the storage portion PC of the packaged item P being accidentally damaged and the contents being exposed to the outside. In addition, by simply releasing the engagement between the locking claw 35 of the cover plate 34 and the locking hole 26 of the front plate 20, the packaged item P can be seen through the window portion 10 of the front plate 20, making it easy to check the packaged item P even if it is packaged in a state where it is completely covered by the cover plate 34 and the back plate 32.

[0081] [Fourth embodiment] <Composition of packaging paper> A fourth embodiment of the packaging mount according to the present invention will be described with reference to Figs.
