Description

TECHNICAL FIELD The present invention relates to a packaging box with cushioning function used for packaging pharmaceuticals and other various articles.

In general, medical drugs such as tablets and capsules handled at medical institutions and dispensing pharmacies are stored in a single PTP sheet in multiple pieces, and this PTP sheet is further pillow-packaged in units of multiple sheets, or They are bound with a binding band, bundled together, and packaged in a packaging box (individual packaging box).

As disclosed in, for example, Patent Document 1, this type of packaging box includes four side plates that are connected in parallel to form a front portion, a back portion, a left side portion, and a right side portion, and one of the side plates. An adhesive piece formed along the side edges of the four side plates, and a pair of flaps and lids formed on both end edges of the four side plates. An adhesive piece on one side edge of the and the other side edge are bonded together. In the process of packaging the drug in this way, the four side plates are folded into a square prism shape, the drug is stored therein, and each part of the bottom lid is folded and adhered, and the top opening of the box is the canopy. It is sealed by the two and assembled into a substantially rectangular parallelepiped shape as a whole. The pharmaceutical product is thus packaged.

In the past, this type of prescription drug was accompanied by a package insert containing various information about the drug, such as the name of the drug, how to take it (dosage, dosage, etc.), efficacy, and handling precautions. It was packed inside the box. The package insert uses a relatively large piece of paper, such as A3 size paper, and is folded into a long and narrow shape so as to be put into the box. The package insert folded in this way is relatively thick. Then, this package insert is stored in a box in a state of being folded into a long and narrow shape, and in such a manner as to sandwich the medicine. By doing so, the package insert holds down the medicine in the box and protects it from shocks outside the box. However, according to the revision of the Pharmaceuticals and Medical Devices Law in November 2019, in principle, this package insert must be provided electronically, and this will be enforced from August 2021. In other words, attachment of package inserts to drugs will be abolished. Since the package insert is not included in the packaging box, it is natural that the box used in the past will have a gap inside the box for the amount of the package insert. There is a risk that the protection performance of the medicine will be reduced due to rattling. For this reason, the conventional box needs to be redesigned.

Japanese Utility Model Laid-Open No. 6-53425

The conventional packaging box (individual packaging box) described above is a package of medicines (PTP sheets in which multiple tablets and capsules are sealed) are pillow-wrapped in units of multiple sheets or tied with a binding band to be bundled. If the size (dimensions) of the box is reduced to match the overall size (dimensions) of pharmaceutical products, the space inside the box will disappear, but if the size of this box is changed, the cartoner (dimensions) will be In addition to the need to adjust the settings of the machine that packs items, it is also necessary to change the size of boxes that contain multiple individual packaging boxes and cardboard boxes that contain multiple boxes. However, there is a problem that the process of packaging pharmaceutical products involves a wide range of changes and a heavy burden.

In addition, in this type of box, there have conventionally been proposed many boxes having a cushioning function for protecting the medicine inside the box.

A trapezoidal upper flap portion 162P forming the left upper flap 16LF is formed continuously via a broken line L7. In one of the composite plate portions 16SP on the right side, a part of the right side plate portion 12P side is provided with one short side of the upper side of the right side plate portion 12P as a lower base, and a half of the length of the upper cover 16C is formed on this short side. An upper flap-shaped portion 161P forming the upper flap 16RF on the right side in a trapezoidal shape slightly shorter than the upper flap portion 161P is continuously formed through the polygonal line L8.

A pair of extension plates 21 and a pair of push-down plates 22 forming a pair of extension plates 21 and a pair of push-down plates 22 are provided at the tip of each upper flap shape portion 162P, 161P, that is, the remainder of each composite plate shape portion 16SP. A plate-shaped portion 21P and a pair of pressing plate-shaped portions 22P are formed together.

A pair of extended plate-shaped portions 21P are formed on the left and right side edges of the upper lid-shaped portion 18P in each composite plate-shaped portion 16SP via folding lines L9 and L10. It is formed in a substantially trapezoidal shape extending outside of the upper lid shape portion 18P, in this case, to the left and right, by being biased upward so as to face the tip side end portions of the left and right side edges of the shape portion 18P.

The pair of pressing plate-shaped portions 22P extend from the intersection X between the lower base of each extension plate-shaped portion 21P and the lower bases of the upper flap-shaped portions 162P and 161P in each composite plate-shaped portion 16SP. and the oblique sides of the upper flap-shaped portions 162P and 161P.

While the blank sheet P1 is conveyed in the direction of travel by a pasting machine (not shown), glue is applied to predetermined portions of the blank sheet P1, and the portions are successively folded as follows. The blank sheet P1 is conveyed with its surface (printing surface) facing downward, and the pedestal-shaped portions 31P at the ends of the lower flap-shaped portions 171P and 172P directed in the traveling direction.

First, in the blank sheet P1, fold lines L20 and L21 are folded in a mountain direction so that the back surfaces of the base-shaped portions 31P (surfaces that are inside when assembled into the box B1 (i.e., inner surfaces)) are aligned 180. Folded. Here, glue is applied to the central portion of the surface side of each fixing plate portion 314P.

Next, in the blank sheet P1, fold lines L12 and L13 are folded into mountain folds, and the front surface of each fixed plate portion 314P after folding each pedestal portion 31P, the rear surface of the front plate portion 11P, and the rear surface of the rear plate portion 13P are folded. are folded 180 degrees so that are aligned with each other. As a result, the front surface of each fixing plate portion 314P, the rear surface of the front plate-shaped portion 11P, and the rear surface of the rear plate-shaped portion 13P are glued together.

Subsequently, the blank sheet P1 is folded along the folding lines L14 and L15 and folded 180 degrees so that the back surfaces of the lower lid-shaped portions 192P and 191P and the back surfaces of the left and right side plate-shaped portions 14P and 12P are aligned with each other. be done. Substantially at the same time, the blank sheet P1 is valley-folded along the folding lines L16 and L17, and is folded 180 degrees so that the surfaces of the lower lid-shaped portions 192P and 191P are aligned with each other.

Here, glue is applied to the central portion of the front surface side of the lower flap-shaped portion 171P and to the central portion of the rear surface side of the lower lid-shaped portion 191P on the leading end side with respect to the folding line L17. Substantially at the same time, glue is applied to the front surface side of the adhesive piece-shaped portion 15P along the folding line L4 in parallel and elongated strips.

Next, in the blank sheet P1, fold the folding line L1 into a mountain fold so that the back surface of the front plate-shaped portion 11P is aligned with the back surface of the right side plate-shaped portion 12P through the base-shaped portion 31P through the lower lid-shaped portion 191P. It can be folded 180 degrees.

Then, in the blank sheet P1, the folding line L3 is folded into a mountain, and the back surface of the left side plate-shaped portion 14P is connected to the back surface of the back plate-shaped portion 13P via the lower lid-shaped portion 192P. 180 degrees to fit through.

In this manner, the blank sheet P1 is flatly folded, and sufficient pressure is applied to the entire blank sheet P1. As a result, the paste-applied portion of the blank sheet P1 and the portion superimposed on this portion are brought into pressure contact and bonded together. That is, the front side of the lower flap shape portion 171P and the back side of the lower lid shape portion 191P are aligned with the tip side of the fold line L17, and the top side of the bottom flap shape portion 172P and the back side of the bottom lid shape portion 192P are aligned from the fold line L16. The tip sides are brought together and glued to each other. Then, the front side of the adhesive piece-shaped portion 15P and the back side of the left side plate-shaped portion 14P are put together and glued together.

Thus, the blank sheet P1 is folded into a flat shape so that it can be assembled into the box B1. The flat box B1 before assembly is packed with cardboard or the like and shipped to a pharmaceutical company.

Then, in the process of packaging vials at a pharmaceutical company, the flat-folded pre-assembled box B1 is raised into a box shape as shown in FIG. 2, and vials are stored inside the box B1. .

In the vial packaging process, the flat box B1 before assembly is raised into a box shape with an open top opening by applying pressure along the folding lines L1 and L3 from the outside to the inside of the box B1. be

That is, between the front plate-shaped portion 11P and the rear plate-shaped portion 13P, the left side plate-shaped portion 14P and the right side plate-shaped portion 12P are raised substantially at right angles to the front plate-shaped portion 11P and the rear plate-shaped portion 13P, respectively. A front plate shape portion 11P, a back shape portion 13P, a left side plate shape portion 14P, and a right side plate shape portion 12P form a front portion, a back portion, a left side portion, and a right side portion, respectively, forming four continuous side plates 11, 13, Assembled as 14,12.

Further, in conjunction with the raising of the left side plate 14 and the right side plate 12, the lower lid shaped portions 192P and 191P are raised substantially perpendicular to the left side plate 14 and the right side plate 12, and the lower lids 18L and 18L are raised. Assembled as 18R. These lower lids 18L, 18R are formed in a substantially square shape under the respective lower flaps 17RF, 17FF at the bottom opening of the box B1, with the oblique sides of the respective bottom lids 18L, 18R aligned on one diagonal line of the bottom opening. Can be combined. In this case, the back surfaces of the portions of the lower lids 18L and 18R on the tip side from the folding lines L16 and L17 are adhered and fixed to the surfaces of the lower flaps 17RF and 17FF via glue.

Furthermore, in conjunction with the raising of the lower lids 18L and 18R, the lower flap-shaped portions 172P and 171P are raised substantially perpendicularly to the rear panel 13 and the front panel 11, and the lower flaps 17RF and 17FF are raised. is assembled as At the same time, each pedestal-shaped portion 31P is assembled as each pedestal 31 in a substantially inverted U shape on the back surfaces of the lower flaps 17RF and 17FF. In this case, each pedestal 31 has its vertical holding plate portion 311P erected at a substantially right angle to each lower flap 17RF, 17FF, and a support groove extending downward from the upper end to the tip of each lower flap 17RF, 17FF. 310, each horizontal holding plate portion 313P is raised substantially at right angles to each vertical holding plate 311 substantially parallel to each lower flap 17RF, 17FF, and each vertical holding plate Each horizontal holding plate 313 has a holding groove 312 continuing to the upper end of the vertical holding plate 311 and continuing to the supporting groove 310 of each vertical holding plate 311 at one end. In this case, each fixing plate portion 314P is fixed as each fixing plate 314 to the rear surface plate 13 and the rear surface of the front plate 11 with glue. Thus, a pair of pedestals 31 are formed on the lower flaps 17RF and 17FF of the bottom lid 17 with a buffer space 30 interposed therebetween, and a vial storage portion 315 is formed between the pedestals 31 in the center of the bottom lid 17. As shown in FIG.

In this way, the main body of the box B1 is assembled except for the top opening, and vials are stored in the storage portion 315 above the center of the bottom cover 17 through the top opening of the box B1.

When the vial is stored in the storage section 315 from the top opening of the box B1, the weight of the vial holds the lower flaps 17FF and 17RF at right angles to the front plate 11 and the rear plate 13. The buffer function part 3 (each pedestal 31) of the bottom lid 17 is retained in its original shape. At this time, each locking piece 316 of each pedestal 31 is engaged with the center of the bottom lid 17, and the shape of the bottom lid 17 is stably maintained.

When the vial is stored inside the box B1 in this way, the top flap shape portions 162P and 161P of the composite shape portions 16SP on the side of the canopy 16 are formed as the top flaps 16LF and 16RF, respectively, and the left side plate 14 and the right side plate 12, and the upper flaps 16LF and 16RF close the top opening of the box B1. At the same time, each push plate shape portion 22P and each extension plate shape portion 21P are pulled by each of the upper flaps 16LF and 16RF, and each push plate shape portion 22P acts as each push plate 22 on the tip of each top flap 16LF and 16RF. Each extension plate-shaped portion 21P is extended as each extension plate 21 from the left and right sides of the upper lid-shaped portion 18P toward the inner surface side of the upper lid-shaped portion 18P.

Then, the upper lid-shaped portion 18P is bent at a substantially right angle with respect to the back plate 13 toward the top opening of the box B1 to form an upper lid 16C. By bending the top lid 16C, as shown in FIG. 3, each extension plate 21 is folded and overlapped on the inner surface of the top lid 16C, and each pressing plate 22 is directed toward the top opening of the box B1 by the top lid 16C and each extension plate 21. pushed in.

When the top lid 16C is folded up to the top opening of the box B1 together with the extension plates 21 and the top opening is closed, the top flaps 16LF and 16RF of the pressing plates 22 are pushed down below the top opening, and the whole is closed. The vial is pushed down into the box B1, and the upper portion of the vial stored in the box B1 is pressed from above by the tip side of each of the upper flaps 16LF, 16RF. In the case of this box B1, as shown in FIG. 4, the tips of the upper flaps 16LF and 16RF together with the tips of the pressing plates 22 form a substantially V-shape from the front plate 11 side to the rear plate 13 side of the box B1. , the top of the vial is pressed and held from above by the tip side of each of the upper flaps 16LF and 16RF. These extension plates 21, push-down plates 22, and upper flaps 16LF and 16RF play a role of cushioning material in place of the attached document.

At the same time when the top opening of the box B1 is closed by the upper lid, the insertion piece-shaped portion 181P of the upper lid 16C is bent inward at a substantially right angle to form an insertion piece 16C1, which is located inside the front plate 11. , and the center of the insertion piece 16C1 and the center of the upper part of the front plate 11 are adhered and fixed via glue. By fixing the upper lid 16C, the upper portion of the vial is held down by the extension plates 21, the pressing plates 22, and the upper flaps 16LF and 16RF inside the upper lid 16C. In this manner, the vials are enclosed in the box B1, and inside the box B1, the vials are supported at their bottom surfaces by the support grooves 310 of the vertical holding plates 311 of the pedestals 31, and their outer peripheral portions are held by the horizontal holding portions 313. The vial is held in the groove 312, and the upper part of the vial is pressed and held by the extension plates 21, the pressing plates 22, and the upper flaps 16LF and 16RF inside the upper lid 16C. As a result, the vial receives the cushioning action of the pedestals 31 on the bottom cover 17, the extension plates 21 on the top cover 16 side, the pressing plates 22, and the upper flaps 16LF and 16RF, thereby sufficiently reducing the impact from the outside of the box B1. and reliably protected.

As shown in FIG. 1, the packaging box B1 is provided with trapezoidal perforations in the upper part of the front plate 11 from the upper edge toward the lower side, and the breaking line C1 for opening is provided. When opening the box B1, the opening surrounded by the breaking line C1 is pressed and broken. As a result, the bonded portion between the upper lid 16C and the front plate 11 is separated, and the top opening of the box B1 can be opened by pulling up the upper lid 16C.

As described above, the packaging box B1 is provided with the buffer function part 2 capable of pressing and holding the upper part of the vial inside the box B1. The vial can be fixed in the box B1 even if a space is left for it. As a result, there is no need to change the size of the box B1, and the effects on others caused by changing the size of the box B1, that is, the need for cartoner setting adjustment work, and the need for multiple individual packaging units It is necessary to change the size of the cardboard box in which multiple boxes are put in, and the size of the cardboard box in which multiple boxes are put in units. be able to.

The cushioning function part 2 includes a pair of extension plates 21 foldably extending on the inner surface of the upper lid 16C on both left and right sides of the upper lid 16C of the canopy 16, and the ends of the pair of extension plates 21 and the canopy 16 A pair of push-down plates 22 are arranged between the top flaps 16LF and 16RF so as to push down and guide the top flaps 16LF and 16RF into the box B1. The top flaps 16LF and 16RF are pressed under the top opening by the pressing plates 22 extending into the box B1, and the top flaps 16LF and 16RF press and hold the upper part of the vial. has a very simple structure, and the cushioning function part can be provided in the box B1 without using many box materials or giving the box material a complicated shape.

In particular, in this packaging box B1, composite plates 16S are formed between the left and right side edges of the top cover 16C and the upper edges of the left and right side plates 14, 12. Each composite plate 16S includes a pair of extension plates 21 are formed on the left and right side edges of the upper lid 16C with these side edges serving as lower bases, and the upper bases are formed in a substantially trapezoidal shape extending outward from the upper lid 16C while being biased toward the tip side of the upper lid 16C. , 16RF are placed on the upper edges of the left and right side plates 14, 12, respectively, with these upper edges as lower bases, and the upper bases are biased toward the ends away from the upper cover 16C, and above the left and right side plates 14, 12. Each push-down plate 22 is formed in a substantially trapezoidal shape extending outward. Since it is formed in a substantially triangular shape between it and the oblique side of 16RF, each part of the cushioning function part can be realized with the simplest possible structure.

Therefore, according to this packaging box B1, it is possible to effectively protect the vials in the box B1 while suppressing an increase in cost.

The packaging box B1 is provided with a cushioning function part 2 on the top cover side and a cushioning function part 3 on the bottom lid side. Since the vial is held from the outside, the impact from the outside of the box B1 can be sufficiently mitigated and the vial can be reliably protected. Furthermore, since the canopy-side cushioning function portion 2 is formed separately from the bottom lid-side cushioning function portion 3, the canopy-side cushioning function portion 2 can be replaced with the bottom lid-side cushioning function portion 3 shown here as an example. Boxes having cushioning functions on the side of the bottom lid of various forms other than the above can also be similarly installed in a simple and low-cost manner, and the same effects can be achieved. In this case, other forms of cushioning function on the side of the bottom cover include those of a type that supports only the bottom portion of the vial within the box and those of a type that holds only the outer peripheral portion of the vial.

Furthermore, since the packaging box B1 including the buffer function parts 2 and 3 can be formed from one sheet of paperboard P1, the manufacturing process can be simplified and the cost can be reduced.

The bottom plates 41 are combined into a horizontally long rectangle by gluing and engaging the convex portions E1 and uneven portions E2 of the bottom plates 41 with each other.

Thus, the box B3 is folded into a flat shape as described above. In the vial packaging process, the box B3 is raised into a box shape, and the vial is stored through the top opening of the box B3.

That is, when the upper lid 16C is folded up to the top opening of the box B3 together with the extension plates 21 and the top opening is closed, as shown in FIG. Pushed down under the face opening, each top flap 16LF, 16RF is pushed down obliquely into box B3. As a result, the top surface of the vial stored in the box B3 is pressed by the presser pieces 221 extending from approximately the center of the tip of each of the upper flaps 16LF and 16RF to the end on the side of the front plate 11, and the upper flaps 16LF and 16RF are pressed. The upper part of the vial housed in the box B3 is pressed and held at the tip side of the box B3.

Even in this way, it is possible to obtain the same effects as those of the second embodiment (however, the effects of the cushioning function portion on the bottom lid side are excluded). Especially in the case of this box B3, since each pressing piece 221 extends from the center of the tip end of each upper flap 16LF, 16RF to the end on the side of the front plate 11, the vial is positioned closer to the front plate than the center of the box B3 in the box B3. When the vial is stored at the position on the 11 side, the pressing pieces 221 can reliably press down the upper surface of the vial.

In the case of this box B3 as well, after opening the canopy 16, when closing the canopy 16, the upper flaps 16LF and 16RF of the canopy 16 are closed with the thumb or forefinger in the same manner as in the second embodiment. The canopy 16 can be closed by pushing it toward the top opening, pressing down the top lid 16C onto the top opening of the box B3 with a thumb or the like, and inserting the insertion piece 16C1 of the top lid 16C into the inside of the front plate 11. can be sealed.
