Description

  The present invention mainly relates to a packaging container for storing an article having a certain length, such as a board gum and a cigarette, and capable of easily taking out the contents.

  When board gum or cigarettes are in the box, there is a problem that it is difficult to take out the contents from the box. Board gum is often wrapped in wrapping paper containing aluminum foil, and cigarettes are also wrapped in paper over the entire side. When the contents packed with such a paper and arranged with a certain length are aligned and packed without a gap, the slipping property between the wrapping papers is small and the frictional resistance is large. Usually, these contents are contained in the box without any gaps, and are often not discharged even if the opening is simply reversed. In particular, if the contents are board gum or cigarettes, the weight of the contents is small compared to the frictional resistance between products, and even if you try to swing out, the force on the product load is small, so it can not be discharged easily. is there.

In Patent Document 1, in a storage box that stores a plurality of sheets upright, a push plate is provided at the bottom of the storage box that is lifted obliquely to push the plurality of sheets to different heights. A sheet storage box is proposed.
Furthermore, a sheet storage box is also proposed in which the push plate is formed by notching the bottom of the storage box.
In the case of this sheet storage box, since the push plate is formed by a notch, when the push plate is pushed up diagonally, a gap is created between the notch and the back of the storage box, and the plate-shaped storage object enters the gap. A problem that cannot be pushed up occurs.
In particular, since the notch is formed in a U-shape, there is a problem in durability such that the push-up plate may be damaged by repeating the push-up operation.

Hereinafter, embodiments of the packaging container of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an example of the packaging container of the present invention, and FIG. 1-1 is a perspective view of the exterior 1 in a state before opening.
The exterior 1 has a sleeve shape having a lid portion that can be opened and closed, and is connected in the order of a front plate 12, a bottom plate 13, a back plate 14, and a lid portion 11, and has a substantially cylindrical shape.
A lid front plate 111 and a lid top plate 112 are connected in order to the lid portion 11, and the lid top plate 112 is connected to the back plate 14 by a hinge 1100.
Further, the front end of the lid front plate 111 is bonded to the front plate 12.

FIG. 1-2 is a perspective view illustrating a state where the exterior 1 is opened.
The opening method in the packaging container of this invention is shown. Before the exterior 1 is opened, the vicinity of the front end of the lid front plate 111 is adhered and fixed to a lock portion 121 provided at the center of the front plate 12.
The front end of the lid front plate 111 is pulled out to the front, and the weak line 1210 provided on the outer periphery of the lock part 121 is cut.
Since the lock part 121 whose outer peripheral line of weakness 1210 is cut is in a state of being adhered to the inner surface of the lid front plate 111 alone, the lid part 11 can be rotated around the hinge 1100.
When the lid 11 is rotated around the hinge 1100 and the entire upper part of the packaging container covered with the lid 11 is opened, a sealing tab 22 covering the take-out port 21 of the product storage bag 2 appears.

FIG. 1-3 is a perspective view showing a state where the exterior 1 is closed again.
The hinge 1100 is rotated to close the lid 11, and the front end of the lid front plate 111 is inserted into the insertion port 122 so as to be sandwiched between the front plate 12 and the product storage bag 2. Then, since the lid 11 is closed, it is designed to prevent the exterior 1 from being inadvertently opened.

FIG. 2A is a perspective view showing a state where the lid 11 is opened, the sealing tab 22 of the product storage bag 2 is peeled off, and the take-out port 21 is opened.
The sealing tab 22 is provided with a tab knob portion 221 that does not have an adhesive layer at the tip, and an adhesive application portion 222 having an openable and closable tack is provided on a portion other than the surface corresponding to the tab knob portion 221 and the outlet 21. The sealing tab 22 is openable and resealable.
For this reason, the pressure-sensitive adhesive used for the pressure-sensitive adhesive application portion 222 of the sealing tab 22 is not only a sheet having a pressure-sensitive adhesive resin layer that can be reattached, but also a resin layer such as polyethylene provided on the surface of the product storage bag 2. The surface is peeled off by the adhesive layer and is not destroyed.
The portion corresponding to the take-out port 21 of the sealing tab 22 may be a method in which a perforation is provided in advance around the entire circumference of the take-out port setting and is cut when the sealing tab 22 is peeled off from the product storage bag by the adhesive force of the sealing tab 22. good.
Since the product storage bag material of the cut-out outlet 21 portion adheres to the portion corresponding to the outlet 21 of the sealing tab 22, the contents do not come into contact with and adhere to the adhesive application portion 222 of the sealing tab. In this method, there is a merit that fine adjustments such as restriction of the sticking position of the sealing tab 22 are not required, compared to a method in which the portion corresponding to the take-out port 21 of the adhesive application portion of the sealing tab 22 is made in advance.

FIG. 2-2 shows a state where the sealing tab 22 is opened and the push-up portion 15 is pushed up.
The push-up portion 15 is composed of a bottom plate 13 of the exterior, a lower portion of the front plate 12 and the back plate 14 connected to the bottom of the exterior, and the periphery of the push-up portion 15 is surrounded by a crease. When pushing up, the bottom plate 13 is pushed up while pushing the lower ends of the front plate 12 and the back plate 14 back and forth.
When the exterior bottom plate 13 is pushed up, the lower end of the product 5 is pushed following the pushed shape, and the upper end of the product 5 jumps out from the take-out port 21.
Adhering the inside of the push-up portion 15 with the product storage bag 2 not only facilitates the tracking of the storage bag when it is pushed up, but also has the merit that it is easy to return to the original shape even when the container is closed, and foreign objects do not easily enter. is there.

FIG. 3 is a longitudinal sectional view of the packaging container according to the first embodiment of the present invention as seen from the side, and FIG. 3A is a state in which the exterior 1 is closed before opening.
There is a frame 4 inside the product storage bag 2 for storing the product 5, and the shape of the product storage bag 2 is maintained. In order not to prevent the frame 4 from pushing up the bottom plate 13, not only the bottom surface but also the lower center of the front and back surfaces of the frame 4 are notched.
The height of the product storage bag is substantially matched to the height of the product 5, and the product tip comes out easily from the outlet when pushed up from the bottom.
There is an exterior 1 around the product storage bag 2. The exterior 1 has a large cutout in the top plate 16, and the cutout portion serves as an outlet for taking out the product. A back margin 17 is provided at the tip of the top plate 16, and is connected to the top plate 16, the front plate 12, the bottom plate 13, and the back plate 14 in order by a crease, and the back plate 14 is connected to the back margin 17. It is formed in a quadrangular cylindrical shape. Further, the lid 11 is connected to the back plate 14 by a hinge 1100, and the lid is composed of a lid top plate 112 and a lid front plate 111.

FIG. 3-2 is a longitudinal sectional view seen from the side, showing a state where the exterior is opened.
When the front end of the lid front plate 111 is pulled out to the front side, the weak line provided on the outer periphery of the lock portion 121 bonded to the inner surface of the lid front plate 111 is cut, and the lock portion 121 is separated from the front plate 12, The front plate 111 can rotate the lid 11 around the hinge 1100.
In the lid portion 11, even the folding rule between the lid upper surface plate 112 and the lid front plate 111 is rotated so that the upper surface side is opened larger.
And the whole upper part of the packaging container covered with the cover part 11 is opened, and the sealing tab 22 which covers the taking-out port 21 of the product storage bag 2 appears.

FIG. 4A is a perspective view seen from the side surface showing a state in which the sealing tab 22 of the product storage bag 2 is peeled off and the outlet 21 is opened in the packaging container with the lid 11 opened.
There is a tab knob portion 221 having no adhesive layer at the tip of the sealing tab 22, and the tab knob is grasped, and the upper surface portion of the resealable sealing tab 22 is peeled off to be opened. Since the upper surface plate 16 is divided into right and left, and the product storage bag 2 is pressed, it is easy to peel off.

In FIG. 4B, the product 5 is pushed up by pushing up the push-up portion 15 in the vicinity of the container bottom plate 13 so that the front end of the product slightly protrudes from the take-out port 21.
When the product 5 is pushed up in this state, since the upper part of the product 5 is exposed from the product storage bag 2, the product 5 is easily grasped.
If the push-up portion 15 of the exterior 1 and the product storage bag 2 are bonded with an adhesive 153 such as a double-sided adhesive tape or a hot melt adhesive, the product can be easily raised and the product can be easily stored even when it is closed. It becomes easy to store the bag 2 on the lower side.

FIG. 5-1 is a longitudinal sectional view as seen from the front side in a state where the exterior is closed.
The product 5 is stored vertically side by side, and the lower end is supported by the bottom plate 13, and the upper end is pressed by the sealing tab 21 and the lid upper plate 112.
There are frames 4 on the left and right sides of the product to support the product storage bag 2.
Further, a push-up crease 151 is provided at the center of the push-up portion 15 centering on the bottom plate.

FIG. 5B is a longitudinal sectional view seen from the front side showing a state in which the lid portion 11 and the sealing tab 22 are opened and the push-up portion 15 is pushed up.
Since the raised crease 151 of the push-up unit 15 is pushed up, the product 5 immediately above the raised crease 151 is pushed up the highest. Furthermore, since the push-up portion 15 is provided with an inclination, the heights at which the adjacent products 5 are pushed up are slightly different from each other. Therefore, it is easy to grasp and discharge only one product.

FIG. 6 is a development view of the exterior 1 in the first embodiment.
From the top, the lid front plate 111 and the lid top plate 112 of the lid portion 11 are connected via a crease, and the back plate 14, the bottom plate 13, the front plate 12, the top plate 16, and the back via the hinge 1100. The margin 17 is connected through a crease.
The push-up portion 15 is connected to the exterior bottom plate 13, and the portions that are connected to the front plate 12 and the back plate 14 have triangular creases with the tangent line 154 connected to the bottom plate 13 as the bottom. In addition, a push-up crease 151 connecting these triangular vertices 152 is provided, and the push-up part 15 is surrounded by the triangle crease. For this reason, when the push-up portion 15 is pushed up, the push-up surface is an inclined surface.
Therefore, when the lower end of the product 5 is pushed by the push-up portion, the product 5 that is immediately above the push-up crease 151 is pushed up highest. Furthermore, the pushed-up heights of the adjacent products 5 are slightly different from each other. As a result, it is easy to grasp and discharge only one product.
It is desirable that a hand that can be bonded to the product storage bag 2 is provided on the push-up portion 15. An adhesive part 153 such as a double-sided adhesive tape is provided at the center of the push-up part, and is adhered to the bottom surface of the product storage bag 2 so that the push-up and storage can be reliably followed by the push-up part of the product storage bag.
The push-up crease 151 connects the vertices 152 of the crease triangles that hang on the front plate 12 and the back plate 14, and extends further by a height corresponding to the height of the triangle than the respective vertices. When extended to the back plate 14, it is easily deformed and easily pushed up.
In addition, when the portion connected to the exterior bottom plate 13 and the front plate 12 and the back plate 14 has a triangular crease like the push-up portion, it can return to the original shape most easily. There is a merit that workability is high.

A large cutout for taking out the product is provided across the front plate 12, the upper plate 16, and the margin 17 on the back. At least the front side and the upper surface side of the sealing tab 22 are not blocked, and a notch with some clearance around the tab knob portion 221 is required. Moreover, the lock part 121 is provided following this notch. The lock portion 121 has a weak line 1210 formed around it, and can be easily separated from the front plate 12 by hand force. Furthermore, an adhesive 1211 such as a double-sided pressure-sensitive adhesive tape or a hot-melt adhesive is applied or applied so that the lock portion 121 is adhered to the inner surface of the lid front plate 111 when assembled.
Further, a glue adhesive 171 such as a double-sided pressure-sensitive adhesive tape or a hot melt adhesive is attached to or applied to the glue 17. Since it is affixed to the marginal adhesive part 170 in the vicinity of the hinge of the back plate 14, the exterior 1 is assembled in a cylindrical shape.

FIG. 7 is a development view of the exterior 1 in the second embodiment.
In 4th Embodiment, the shape concerning the front board 12 and the back board 14 of the raising part 15 is made into a trapezoid instead of a triangle. Compared to the triangular shape of the back plate 14, the ease of returning the bottom plate after extruding the product is reduced, but if the product is soft, it can be pushed up without being deformed when extruding. it can.

FIG. 8 is a development view of the exterior 1 in the third embodiment.
In 5th Embodiment, the shape concerning the front board 12 and the back board 14 of the raising part 15 is made into a dome shape instead of a triangle. Compared to a triangle, the shape of the back plate 14 is lower than that of a triangle, but the ease of return of the bottom plate after extruding the product is reduced. Since the surface is configured by a curve, it is an example of a shape that is easy to push up because the shape is not unreasonable. In this case, many push-up creases 151 are provided.

FIG. 9 is a development view of the exterior 1 in the fourth embodiment.
In the sixth embodiment, the lock portion is moved upward as much as possible, and the insertion port 1210 is independent. Since the insertion slot is cut and there are walls on the top and bottom, the lid front plate 111 is firmly sandwiched to prevent the lid from jumping up.
The tab tab 221 of the sealing tab is made as small as possible.

FIG. 10A is a perspective view illustrating an appearance of the product storage bag 2.
The outlet 21 is provided only on one surface of the product storage bag 2 which is a hexahedron, and is not provided extended on the other surface. This is because it is desirable to fix the periphery of the take-out port 21 where the adhesive coating portion is pasted as a flat surface so that the sealing tab 22 can be stably sealed again.
In particular, since the thickness of the seal portion varies greatly and the surface cannot be kept flat, it is difficult to seal the seal portion. It is preferable to design so as not to come.
As shown in FIG. 10-2, the sealing tab 22 is adhered and sealed. The attaching direction of the sealing tab 22 is not limited to the direction shown in this figure. If the contents are not stick-shaped products and not the full width product of the product storage bag 2, and if the upper surface is provided with a sealing tab, the peeling direction may be set sideways as shown in FIG. 10-3. .

FIG. 11A is a perspective view seen from the opposite direction of FIG. The position of the back seal 23 of the product storage bag 2 is preferably close to the lower end if possible, and may be provided on the bottom side. The left side seal 24 and the right side seal 25 in the product storage bag have a shape in which the top seal and the ground seal in a normal bag are rotated 90 degrees so as to be in the left-right direction. It doesn't matter. A seal that can maintain the shape of a hexahedron as much as possible is preferable.
11-2 shows the state in which the sealing tab 22 is opened, and the adhesive application part 222 is preferably removed from the part corresponding to the outlet 21 and the tab knob part 221 as shown in this figure.

The component film of the product storage bag 2 depends on the storage stability required for the contents, but from the outside, polyethylene / polyethylene terephthalate / aluminum foil / polyethylene / polyamide / polyethylene,
Polypropylene / aluminum foil / polyethylene / polyamide / polyethylene,
Polyethylene terephthalate / aluminum foil / polyethylene,
Polypropylene / aluminum foil / polyethylene / paper / polyethylene,
Etc. are considered.
The aluminum foil plays the role of not letting out the scent, and the thickness is 5 to 15 micrometers. A polyethylene oxide vapor deposited polyethylene film or the like may be substituted. Moreover, 6-25 micrometers etc. can use the thickness of a polyethylene terephthalate film.
These films can be produced by a normal dry lamination machine, an extruder laminating machine or the like.

FIG. 12 is an example of the frame 4, FIG. 12-1 is a development view thereof, and FIG. 12-2 is an assembly view thereof.
The frame 4 has a cylindrical shape with a rectangular cross section with at least an open top.
The frame 4 is disposed inside the product storage bag 2. In particular, when there is no significant difference between the inner size of the product storage bag and the size of the frame, it is easy to maintain the shape and exert its role even if the product storage bag 2 and the frame 4 are not firmly bonded and fixed.
The frame 4 has no bottom side, is cut out at the center, and is made without any difficulty in pushing up the push-up portion.

The thickness of the base paper that forms the exterior 1 and the frame 4 of the present invention is adjusted according to the weight of the contents to be stored. Usually, the basis weight which is the thickness of paper can be used in the range of 120 g / m ² to 400 g / m ² . Further, the density of the paper is set in the range of 0.6 to 1.1 g / cm ³ .
In addition, a laminated sheet may be used to improve water resistance by using a thermoplastic resin on the inner surface, the outer surface, or both surfaces of the base paper, and the material is not particularly limited.

The packaging container according to the present invention is as described above, and the elongated contents are stored in an aligned manner, and by pushing up the push-up portion, the height of the vertically aligned products can be changed and popped out of the product storage bag. It can be easily removed one by one.
In addition, since the bottom plate can be easily returned to the original position, it is easy to work even when it ends up.
Further, the vicinity of the bottom surface to be pushed out is clean because the bag is closed and there is no possibility of foreign matter entering.
Furthermore, since the exterior bottom face to be pushed out and the storage bag are bonded, there is no gap for foreign matter to enter, and malfunction due to the foreign matter is unlikely to occur.
Moreover, since the bottom surface is not cut out, the durability is high, and even if the bottom portion is repeatedly raised and lowered, it is difficult to break.
Furthermore, since it cannot be opened unless the bonded lock part is broken, virginity is ensured and mass production is possible with normal production machines, so productivity is high and cost increases are minimized. There are significant benefits such as being suppressed.
