Description

  The present invention is a product packaging box for storing and displaying products such as cosmetics and pharmaceuticals in a product storage area, and in particular, a correct display with a curved display surface with high design that improves the added value of the product. The present invention relates to a product packaging box that stores and displays products in a product storage area surrounded at least by a face plate, a back plate, and a cover plate.

Conventionally, as a product packaging box for storing and displaying products, a storage portion for storing products and an insertion portion for closing the opening of the storage portion are provided, and the storage portion is suspended from a hook such as a display display wall. There is a packaging box that extends the hanging part.
Such a packaging box is formed by forming the locking piece on the extended base end side of the hanging portion and forming the locking hole at a position corresponding to the locking piece of the insertion portion. When closing the opening of the storage portion, the locking piece is inserted into the locking hole by forcibly bending the hanging portion to the back side, and the locking piece and the locking hole are engaged, while the storage portion When opening, the hanging portion is bent again to the back side, and the engagement between the locking piece and the locking hole is released (for example, see Patent Document 1).

In addition, as another conventional product packaging box, a container body having an opening and a lid for closing the opening are provided, and the lid is cut in a direction to rotate from the closed state to the opened state. There is a packaging container in which a raised locking piece is formed and a locked portion that engages with the locking piece is formed on an auxiliary plate standing on the container body.
And when such a packaging container rotates the cover part from the closed state to the open state, the locking piece is difficult to come off from the locked part, and the sealed state is firmly maintained ( For example, see Patent Document 2).

The left side plate 141 and the back left bottom base 157 are bent in a mountain fold so that the left side plate lower end crease line BL13 has an obtuse angle with each other.
After the back right bottom base 158 is folded into a valley fold at the back left bottom base central crease line BL17, the back side bottom base 156 and the back right bottom base 158 are obtuse to each other at the back side bottom base right end crease line BL15. The right side plate 142 and the rear right side bottom base 158 are bent in a mountain fold so that they are mutually obtuse at the right side plate lower end crease line BL16.

  Then, as shown in FIG. 4, the lower half of the front side bottom base center crease line BL11 provided at the center of the outer side surface of the front side bottom plate 151 and the upper half of the outer side surface of the back side bottom base 156 are bonded as an example. The bottom plate 150 of the product packaging box 100 is formed by bonding with the agent.

After the product M is stored in the product storage region R, the cover plate 130 and the back side folded plate 180 are folded in a mountain so that the cover plate upper end crease line BL21 is approximately 90 degrees as shown in FIG. It can be bent.
Next, the lid plate main body 131 and the lid plate left side flap 132 are folded in a mountain fold so that the lid plate left upper end crease line BL22 is approximately 90 degrees to each other. 133 is folded in a mountain fold so that the upper right end crease line BL23 of the cover plate is approximately 90 degrees from each other.
Thereafter, as shown in FIG. 5, the back plate 120 and the lid plate main body 131 are folded in a mountain fold so that the back plate upper end crease line BL <b> 20 is approximately 90 degrees.

Then, as shown in FIGS. 6 and 7, the front side folded plate 160 and the knob piece 170 are folded in a valley fold so that the front side folded plate upper end fold line BL19 is substantially 90 degrees to each other. 110 and the front side folded plate 160 are folded in a mountain fold so that the front plate upper end crease line BL18 is approximately 90 degrees from each other.
Then, as shown in FIG. 7, the assembly of the product packaging box 100 is completed by inserting and locking the locking tongue piece 161 into the locking slit SL1.

And as above-mentioned, the product packaging box 100 of this reference example accommodates the product M in the product accommodation area | region R, and is the front side even if it is the front plate 110 taller than the backplate 120. The folding plate 160 and the back folding plate 180 are superimposed on the back surface of the front plate 110 to reinforce the front plate 110, and even when viewed from obliquely above, only the product information is displayed without showing the lid plate 130. It becomes easy to see.
When the lid plate 130 is closed, the back side folding plate 180 of the lid plate 130 is sandwiched between the back surface of the front plate 110 and the front side folding plate 160, and the knob piece 170 is gripped by the front side folding plate 160 and the knob. The closing position of the lid plate 130 is positioned and held by a bend line with the piece 170, and the engagement tongue piece 161 is reliably maintained in engagement with the engagement slit SL1.
Further, when the lid plate 130 is closed, the back side folded plate 180 of the lid plate 130 is held between the back surface of the front plate 110 and the front side folded plate 160 so as to be overlapped. Even if the cover plate sinks inadvertently when the plate 130 is closed, contact resistance is created between the back surface of the front plate 110 and the opposed surface of the front folded plate 160 to suppress the drop of the cover plate 130. When the height dimension of the product M accommodated in the product accommodation region R at least surrounded by the front plate 110, the back plate 120, and the lid plate 130 reaches the closed position of the lid plate 130, the lid inadvertent drop of the plate 130 is completely prevented.

In the product packaging box 100 of the present reference example , before the product is stored in the product storage area, or after the product is taken out from the product storage area, the bottom plate 150 has the front side bottom base center crease line BL11. Since the front plate right end crease line BL1 and front plate left end crease line BL2 are folded in a mountain and the front side bottom base center crease line BL11 is folded in a valley fold, The packaging box 100 is maintained in a flat and compact state.

Next, when the product M is taken out from the product storage area R of the product packaging box 100 which is a reference example of the present invention, the locking tongue 161 and the locking slit SL1 are unlocked when the lid is opened. The principle will be described with reference to FIGS.

First, when the lid plate 130 is closed, the back-side folded plate 180 of the lid plate 130 is sandwiched between the back surface of the front plate 110 and the front-side folded plate 160 and is superposed integrally with each other.
Thereby, even if it is the front board 110 taller than the back board 120, the front side folding board 160 and the back side folding board 180 are piled up on the back surface of the front board 110, and the front board 110 is reinforced.
At this time, as shown in FIG. 8, the knob piece 170 positions and holds the closed position of the lid plate 130 with the fold line between the front side folding plate 160 and the knob piece 170, and the locking tongue piece 161 has the locking slit. The locked state is inserted into SL1.

  Next, as shown in FIG. 9, when the pulling up is started so as to separate the front side folded plate 160 manually when the lid plate is opened, the front plate 110 and the rear side folded plate 180 are not deformed, and therefore the knob piece 170 is not deformed. However, without being affected by the internal stress generated by the distortion of the front plate 110 that curves toward the outer peripheral side of the box, the locking tongue piece 161 is guided and started to be pulled out from the locking slit SL1.

And as shown in FIG. 10, the base end part along the front side folded board upper end part crease line BL19 of the latching tongue piece 161 will be in a state just before being pulled out from latching slit SL1 by elastically deforming suddenly. .
Even at this time, the front plate 110 and the back side folded plate 180 are still not deformed.

Further, when the pulling force by the knob piece 170 exceeds a predetermined value and the front side folded plate 160 is elastically deformed as shown in FIG. 11, the locking tongue piece 161 may remain in the locking slit SL1. It cannot be pulled out from the locking slit SL1.
As a result, the knob piece 170 releases the locking state between the locking tongue piece 161 and the locking slit SL1.

A product packaging box 100, which is a reference example of the present invention thus obtained, swells to the front side of the outer periphery of the box and curves toward the outer side of the box, and the back surface of the front plate 110. A short back plate 120 arranged oppositely on the rear side of the outer periphery of the box, a lid plate 130 connected to the upper side of the back plate 120 and opened and closed, the front plate 110, the back plate 120, and a pair of left and right side plates 140, 140, a bottom plate 150 connected to the lower side of the front plate 110, a front side folded plate 160 connected to the upper side of the front plate 110, a knob piece 161 extending above the front side folded plate 160, and a lid plate 130 By providing the back side folded plate 180 extending upward, the shape retention and the excellent shape retention strength of the front plate 110 having the curved display surface can be ensured over a long period of time. High design Exhibit aesthetics, moreover, to reliably prevent the lid off by inadvertent lifting of the cover plate 130 in the knob piece 170 at the time of closing of the cover plate 130.

In particular, in the product packaging box 100 which is a reference example of the present invention, the locking tongue piece 161 formed by cutting the knob piece 170 and the locking slit formed by cutting between the lid plate 130 and the back side folding plate 180. By providing SL1, the release operation burden required when the locking tongue piece 161 as in the prior art is directly pulled out from the locking slit SL1 is remarkably reduced. The locked state with the locking slit SL1 is simply released .

Below, the product packaging box 200 which is 1st Example of this invention is demonstrated based on FIG. 12 thru | or FIG.
Here, FIG. 12 is a rear perspective view in which the cover plate of the product packaging box according to the first embodiment of the present invention is opened, and FIG. 13 is related to the locking tongue piece according to the first embodiment of the present invention. FIG. 14 is a cross-sectional view showing a state immediately before the locking tongue piece and the locking slit shown in FIG. 13 are released, and FIG. 15 is a cross-sectional view showing the locking state shown in FIG. It is sectional drawing of a state immediately after cancellation | release of a tongue piece and a latching slit.

The product packaging box 200 according to the first embodiment of the present invention employs a locking tongue piece 261 having a different form from the locking tongue piece 161 in the product packaging box 100 of the reference example described above. Since the box shape is the same as that of the product packaging box 100 of the reference example , the detailed description of the common items is omitted by attaching the reference number 200 in common with the last two digits.

That is, as shown in FIG. 12, the product packaging box 200 according to the first embodiment of the present invention has a front plate 210 that bulges and curves toward the front side of the outer periphery of the box, and a rear side of the outer periphery of the box that faces the front plate 210. A back plate 220 arranged on the side, a lid plate 230 provided on the upper side of the back plate 220 via a bend line, and a pair of left and right connecting the front plate 210 and the back plate 220 via the bend line. Side plates 240, 240, a front plate 210, a back plate 220, a bottom plate 250 connected to the lower side of the pair of left and right side plates 240, 240 via a fold line, and an upper side of the front plate 210 via a fold line. A front-side folded plate 260 provided, a knob piece 270 extending above the front-side folded plate 260 via a folding line, and a back-side folded folded above the lid plate 230 via a folding line. 280 a series to consist coated paper comprised of, to form a product receiving region R which is surrounded by these front plate 210 and rear plate 220 and a pair of right and left side plates 240, 240 and bottom plate 250.

  Then, as shown in FIG. 12, the locking tongue piece 261 that is the most characteristic of the product packaging box 200 of the second embodiment is cut in parallel to the knob piece 270 side along the front side folded plate upper end fold line BL19.

It is formed by a knob piece side left side cutout CT13 formed on the front side folded plate 260 side beyond.

Next, when the product M is taken out from the product storage area R of the product packaging box 200 according to the first embodiment of the present invention, the locked state of the locking tongue piece 261 and the locking slit SL1 is released. The principle of operation will be described with reference to FIGS.

First, as shown in FIG. 13, when the lid plate 230 is closed, the back-side folded plate 280 of the lid plate 230 is sandwiched between the back surface of the front plate 210 and the front-side folded plate 260, and is integrated with each other. It is superimposed.
Thereby, even if it is the front plate 210 taller than the back plate 220, the front side folded plate 260 and the back side folded plate 280 are overlapped on the back surface of the front plate 210, and the front plate 210 is reinforced.
At this time, as shown in FIG. 13, the knob piece 270 positions and holds the closed position of the lid plate 230 at the folding line between the front-side folded plate 260 and the knob piece 270, and the locking tongue piece 261 is locked. The locked state inserted into the slit SL1 is exhibited.

  Next, as shown in FIG. 14, when the lid plate 230 is opened, when the pulling up is started so that the front side folded plate 260 is separated manually, the front plate 210 and the back side folded plate 280 are not deformed. 270 is guided by the locking tongue piece 261 and pulled out from the locking slit SL1 without being affected by the internal stress generated by the distortion of the front plate 210 that curves toward the outer peripheral side of the box. .

Then, the length of the locking tongue piece 261 is longer than the product packaging box 100 in which the length of the locking tongue piece 161 as in the reference example does not exceed the folding line between the knob piece 170 and the front side folding plate 160. Becomes longer, the degree of elastic deformation of the locking tongue piece 261 and the front-side folded plate 260 increases, and it becomes easier to adapt to the pulling direction of the knob piece 270, and is pulled out from the locking slit SL1 as shown in FIG. It will be on the verge.
Even at this time, the front plate 210 and the back-side folded plate 280 are not deformed yet.

As described above, when the pull-out force by the knob piece 270 exceeds a predetermined value and the front side folded plate 260 is greatly elastically deformed, the locking tongue piece 261 cannot remain in the locking slit SL1, It is pulled out from the locking slit SL1.
As a result, the knob piece 270 releases the locking state between the locking tongue piece 261 and the locking slit SL1.

Further, in the product packaging box 200 of the first embodiment , the pair of left and right tongue-shaped tongue pieces 261 a and 261 a formed on the locking tongue piece 261 are bent between the knob piece 270 and the front side folding plate 260.

Thereby, when the knob position of the knob piece 270 is biased to either the left or right position of the knob piece 270, or when the pulling direction of the knob piece 270 is biased from the right rear direction of the front plate 210 to either the left or right direction. Even so, the front side folded plate side notch portions of the side portions 261a and 261a of the tongue-shaped tongues notched to the biased side can more easily follow the lifting operation of the knob pieces 270 being biased. Yes.

In the product packaging box 200 according to the first embodiment of the present invention thus obtained, the locking tongue piece 261 has the knob piece 270 and the front surface in addition to the effect exhibited by the product packaging box 100 of the reference example described above. Since the notch is formed on the side of the front side folding plate 260 beyond the folding line between the side folding plate 260 and the length of the locking tongue piece 161 as in the above-described reference example , Since it becomes longer than the product packaging box 100 that does not exceed the folding line between the side folded plate 160 and the degree of elastic deformation of the locking tongue piece 261 increases, it becomes easier to adapt to the pulling direction of the knob piece 270. When the unlocking operation of the locking tongue piece 261 for opening the lid and the locking slit SL1 is started, the locking tongue piece 261 can be smoothly pulled out and released from the locking slit SL1.

  Moreover, the pair of left and right sides of the hook-shaped tongue piece 261a, 261a formed on the locking tongue piece 261 intersects with the fold line between the knob piece 270 and the front side folded plate 260, and are inwardly directed to each other. Due to the notch, the knob position of the knob piece 270 is biased to either the left or right position of the knob piece 270, or the pulling direction of the knob piece 270 is either right or left from the rear side of the front plate 210. Even when it is biased in the direction, when the unlocking operation of the locking tongue piece 261 for opening the lid and the locking slit SL1 is started, the knob position of the knob piece 270 by the dominant hand or the like in the pulling direction The engagement tongue piece 261 can be smoothly pulled out and released from the engagement slit SL1 without being involved, and the effect is enormous.

Hereinafter, a product packaging box 300 according to a second embodiment of the present invention will be described with reference to FIGS.
Here, FIG. 17 is a rear perspective view showing the appearance of the product packaging box according to the second embodiment of the present invention, and FIG. 17 is an exploded view of the product packaging box according to the second embodiment of the present invention. 18 is a rear perspective view of the product packaging box according to the second embodiment of the present invention in which the cover plate is opened, and FIG. 19 is related to the locking tongue piece viewed from 19A-19A in FIG.

FIG. 22 is a cross-sectional view showing a state immediately before the tongue piece and the locking slit are released, FIG. 22 is a cross-sectional view showing a state where the notch interruption point shown in FIG. 16 is broken, and FIG. It is sectional drawing of a state immediately after cancellation | release of a tongue piece and a latching slit.

The product packaging box 300 according to the second embodiment of the present invention is different from the locking tongue piece 161 in the product packaging box 100 of the reference example described above and the locking tongue piece 261 in the product packaging box 200 of the first embodiment. The shape of the locking tongue piece 361 is adopted, and the basic box shape is common to the product packaging box 100 of the reference example and the product packaging box 200 of the first embodiment. The detailed description will be omitted by giving the reference number 300 in common with the last two digits.

That is, as shown in FIG. 17, the product packaging box 300 according to the second embodiment of the present invention has a front plate 310 that bulges and curves toward the front side of the outer periphery of the box, and a rear side of the outer periphery of the box that faces the front plate 310. A back plate 320 arranged on the side, a lid plate 330 connected to the upper side of the back plate 320 via a bend line, and a pair of left and right connecting the front plate 310 and the back plate 320 via the bend line. The side plates 340, 340, the front plate 310, the back plate 320, the bottom plate 350 connected to the lower side of the pair of left and right side plates 340, 340 via a fold line, and the upper side of the front plate 310 via the fold line. A front-side folded plate 360 provided, a knob piece 370 extending above the front-side folded plate 360 via a folding line, and a back-side folded folded above the lid plate 330 via a folding line. 380 a series to consist coated paper comprised of, to form a product receiving region R which is surrounded by these front plate 310 and back plate 320 and a pair of right and left side plates 340, 340 and bottom plate 350.

As shown in FIGS. 17 and 18, the locking tongue piece 361, which is the most characteristic of the product packaging box 300 according to the second embodiment of the present invention, has a front side folded plate upper end fold line on the knob piece 370 side. A front end side cutout CT11 cut in parallel along BL19, and a front side folded plate upper end fold line BL19 that becomes a fold line between the knob piece 370 and the front side folded plate 360 from the right end portion of the front end side cutout CT11. And the front-side folded plate 360 formed on the front-side folded plate 360 side, and the front-side folded serving as a fold line between the knob-piece 370 and the front-side folded plate 360 from the left end of the front-side cut-out CT11. It is formed with a knob piece side left-side cutout CT13 formed on the front side folded plate 360 side beyond the plate upper end crease line BL19.

Next, when the product M is removed from the product storage area R of the product packaging box 300 according to the second embodiment of the present invention, the locked state between the locking tongue piece 361 and the locking slit SL1 is released. The operating principle will be described with reference to FIGS.

First, as shown in FIG. 19, when the lid plate 330 is closed, the back-side folded plate 380 of the lid plate 330 is sandwiched between the back surface of the front plate 310 and the front-side folded plate 360 so as to be integrated with each other. Are superimposed.
Thereby, even if the front plate 310 is taller than the back plate 320, the front side folded plate 360 and the back side folded plate 380 are superimposed on the back surface of the front plate 310, and the front plate 310 is reinforced. ing.
At this time, as shown in FIG. 19, the knob piece 370 positions and holds the closed position of the lid plate 330 at the folding line between the front side folding plate 360 and the knob piece 370, and the locking tongue piece 361 A strong locking state inserted into the slit SL1 is exhibited.

  Next, as shown in FIG. 20, when the cover plate 330 is opened, if the knob piece 370 is pulled up manually, the front plate 310 and the back side folding plate 380 are not deformed, and therefore, curve toward the outer peripheral side of the box. The knob piece 370 locks the locking tongue piece 361 so that the front side folded plate 360 is separated from the front plate 310 and the back side folded plate 380 without being affected by the internal stress generated by the distortion of the front plate 310. The guidance starts to be pulled out from the slit SL1.

Then, as shown in FIG. 21, the base end portion along the front side folded plate upper end fold line BL19 of the locking tongue piece 361 is suddenly elastically deformed and is in a state just before being pulled out from the locking slit SL1.
Even at this time, the front plate 310 and the back side folded plate 380 are not deformed yet.

When the pulling force by the knob piece 370 exceeds a predetermined value, the notch interruption point P provided on the front side folding plate immediately after the folding line between the knob piece 370 and the front side folding plate 360 is broken. 22, the length that can be deformed as the locking tongue piece 361 is increased, the degree of elastic deformation of the locking tongue piece 361 and the front-side folded plate 360 is increased, and the locking tongue piece 361 is gripped. It becomes easy to adapt to the pulling-up direction of the piece 370.
Further, when the pulling force by the knob piece 370 breaks the notch interruption point P, the pulling force by the knob piece 370 is dispersed so as to be temporarily suppressed at the notch interruption point P.

  Then, as shown in FIG. 23, when the front-side folded plate 360 is further elastically deformed, the locking tongue piece 361 cannot remain in the locking slit SL1, but is pulled out from the locking slit SL1, and as a result The knob piece 370 releases the locking state between the locking tongue piece 361 and the locking slit SL1.

The product packaging box 300 according to the second embodiment of the present invention thus obtained is an effect of the product packaging box 100 of the reference example described above, that is, a front plate having a curved display surface with high design. Excellent shape retention strength and form stability are ensured over a long period of time, and the knob piece 370 reliably prevents the lid plate 330 from coming off due to inadvertent lifting, thereby locking the conventional locking tongue piece. In addition to the effect that the unlocking operation load required when pulling out directly from the slit is remarkably reduced and the locking state between the locking tongue 361 and the locking slit SL1 is simply released by the knob piece 370, the locking Excluding the notch interruption point P on the front-side folded plate 360 side immediately after the tongue piece 361 exceeds the front-side folded plate upper end fold line BL19 that is a folding line between the knob piece 370 and the front-side folded plate 360. Thus, when the pull-out force by the knob piece 370 exceeds a certain level, the cut-out interruption point P is first broken and can be deformed as the locking tongue piece 361. Since the length becomes long and the degree of elastic deformation of the locking tongue piece 361 increases and it becomes easy to adapt to the pulling direction of the knob piece 370, the engagement between the locking tongue piece 361 for opening the lid and the locking slit SL1. The locking tongue piece 361 can be smoothly pulled out from the locking slit SL1 when starting the release operation, and the locking tongue piece is not damaged by the breakage of the notch interruption point P. It is also possible to easily pull out 361 from the locking slit SL1 and easily confirm the fact that the lid has been opened after the product packaging box 300 is shipped.

  Further, the pair of left and right sides of the hook-shaped tongue piece 361a, 361a formed on the locking tongue piece 361 intersects with the folding line between the knob piece 370 and the front-side folded plate 360 so as to be inward of each other. Due to the notch, the knob position of the knob piece 370 is biased to either the left or right position of the knob piece 370, or the pulling direction of the knob piece 370 is either right or left from the right rear direction of the front plate 310. Even when it is biased in the direction, when the unlocking operation of the locking tongue piece 361 for opening the lid and the locking slit SL1 is started, the knob position of the knob piece 370 by the dominant hand or the like in the pulling direction The engagement tongue piece 361 can be smoothly pulled out and released from the engagement slit SL1 without being involved, and the effect is enormous.
