Description

  The present invention relates to a packaging container.

 2. Description of the Related Art As a container for a gift box or the like, a packaging container in which a partition is provided in a cubic box such as cardboard or cardboard is known in order to pack a plurality of containers in a package. As such a packaging container, a body-type packaging material in which a main body and a lid are individually molded, or a cylindrical sleeve by sticking both ends of one blank, and a specification that closes both open ends of the sleeve is used. Sack pasting packaging materials are used frequently. The sack pasting packaging material is manufactured by a sack pasting machine, and delivered in a folded state so that the two surfaces face each other. And when packing a to-be-packaged item, since it is easily assembled into a predetermined shape, the sachet packaging material is highly convenient.

Some packaging containers used for gifts and the like have enhanced design and functionality by inflating a part of the surface portion forming the packaging container to the outside.
As a packaging container in which the top surface portion is inflated to the outside in this way, for example, a pentagonal end plate is connected to one opposite side of a rectangular bottom plate, an inner plate is connected to two sides on the bottom plate side of the end plate, and the other two The inner top plate is connected to each side, and the side plate and the outer top plate of the size corresponding to each side length of the end side are connected to the other opposite side of the bottom side, and the insertion piece and the handle plate are connected to the outside of the outer top plate. Assembling-type portable containers composed of a single development plate connected to each other have been proposed (for example, Patent Document 1).
Since it cannot fold when the invention of patent document 1 is made into a sachet packaging material, it is delivered with a single development plate (blank). For this reason, it is complicated to assemble in a predetermined shape.

For such problems, for example, in a pentagonal column box having a pentagonal side wall whose horizontal section is symmetrical with respect to the center line in the front-rear direction, a foldable pentagonal column box having a fold line at the longitudinal center in one of the side walls Has been proposed (for example, Patent Document 2). According to invention of patent document 2, it can be made the sack pasting packaging material folded by the fold line formed in the vertical center in one of the side walls.
In addition, for example, a front plate, a side plate, a back plate, and a side plate that are connected in sequence, a small flap that is connected to the upper ends of both side plates, and a front plate and a rear plate that are connected to the upper ends, respectively. There has been proposed a paper box that is composed of a roof plate and a bottom portion, and has a shape in which the upper sides of both side plates protrude in a mountain shape, and a small flap is attached to the roof plate (for example, Patent Document 3).

Japanese Utility Model Publication No. 2-40020 Japanese Utility Model Publication No. 1-110123 Japanese Patent Laid-Open No. 7-257545

However, in the invention of Patent Document 2, a folding line that is used only for folding the sachet packaging material is formed on a part of the side wall. For this reason, the said broken line becomes a factor which impairs the designability and intensity | strength of the packaging container after an assembly. In invention of patent document 3, the special apparatus for bonding a roof plate is needed.
Therefore, the present invention has an object of a packaging container that is excellent in design properties, easy in assembly operation, and can be manufactured with a general-purpose sack pasting machine without impairing strength.

The packaging container of the present invention includes a first surface portion that is rectangular in plan view, a second surface portion that faces the first surface portion, and a third surface that is connected to the first surface portion and the second surface portion. A surface portion, a fourth surface portion facing the third surface portion and connected to the first surface portion and the second surface portion, the first surface portion, the second surface portion, and the third surface portion. And a fourth surface portion that closes one open end of the cylindrical body formed by the fourth surface portion, and a sixth surface portion that closes the other open end of the tubular body, In the packaging part in which a ridge line extending from the fifth surface part toward the sixth surface part is formed on the surface part, the boundary between the first surface part and the third surface part is between the fourth surface part and the fourth surface part. The length L1 to the boundary is shorter than the length L2 from the boundary with the third surface portion to the boundary with the fourth surface portion in the second surface portion. The length L3 from the boundary with the first surface portion to the boundary with the second surface portion in the third surface portion is the second length from the boundary with the first surface portion in the fourth surface portion. It is shorter than the length L4 to the boundary with the surface portion, and the sum of L1 and L4 is equal to the sum of L2 and L3.
The third surface portion and the fourth surface portion are preferably substantially parallel.

It is a schematic diagram of the sack pasting packaging material using the blank of FIG.

The packaging container according to the first embodiment of the present invention will be described below with reference to FIGS.
The packaging container 1 in FIG. 1 is connected to a first surface portion 10 having a rectangular shape in plan view, a second surface portion 20 having a rectangular shape facing the first surface portion 10, and the first surface portion 10 and the second surface portion 20. A cylindrical body formed by the rectangular third surface portion 30 and the rectangular fourth surface portion 40 facing the third surface portion 30 and connected to the first surface portion 10 and the second surface portion 20. 2 is provided. The packaging container 1 includes a fifth surface portion 50 that closes one open end of the tubular body 2, and a sixth surface portion 60 that closes the other open end of the tubular body 2.
On the second surface portion 20, a ridge line 21 extending from the fifth surface portion 50 toward the sixth surface portion 60 is formed, and a handle portion 70 erected from the ridge line 21 is provided. The ridge line 21 is formed at a position that bisects the length from the boundary 22 with the third surface portion 30 to the boundary 24 with the fourth surface portion 40 in the second surface portion 20.
In the present embodiment, the first surface portion 10 is a bottom surface, the second surface portion 20 is a top surface, and the third surface portion 30 and the fourth surface portion 40 are substantially parallel. Being substantially parallel means that the third surface portion 30 and the fourth surface portion 40 can be visually recognized as parallel.

In the plan view, the first surface portion 10 is a rectangle having a boundary 12 with the third surface portion 30 as a longitudinal direction, and the second surface portion 20 is a rectangle having a boundary 22 with the third surface portion 30 as a length. Has been.
In the front view, the third surface portion 30 is a rectangle having a boundary 12 with the first surface portion 10 as a longitudinal direction, and the fourth surface portion 40 is a rectangle having a boundary 14 with the first surface portion 10 as a longitudinal direction. Has been.

As shown in FIG. 2, the packaging container 1 has a pentagonal shape in a side view with the first surface portion 10 as a bottom and the ridge line 21 as a protruding end. That is, the fifth surface portion 50 and the sixth surface portion 60 are pentagonal when viewed from the side.
In the side view, the fifth surface portion 50 has a short boundary with the first surface portion 10, and the sixth surface portion 60 has a short boundary with the first surface portion 10. The fifth surface portion 50 and the sixth surface portion 60 have the same shape and the same size.

 The material of the packaging container 1 may be any material that can be bent and can be determined in consideration of the strength required for the packaging container 1. Examples of the material of the packaging container 1 include a paper material that is a paper or a molded product of paper, a resin such as polyethylene, polypropylene, and polyester, a metal such as aluminum, and a resin layer or metal layer on a paper material. For example, a laminate provided with.

 Paper is a concept including “paperboard” defined by JIS P0001 in addition to “paper” defined by JIS P0001. Further, “made of paper” is a concept including “corrugated cardboard” defined by JIS Z0104, which is a molded product of paper and paper.

As the material of the packaging container 1, among paper, cardboard base paper such as liner paper, paperboard board such as white paperboard and color paperboard, paperboard such as miscellaneous paperboard such as waterproof base paper and paper tube base paper, and corrugated cardboard are preferable. Since paperboard and corrugated cardboard are self-supporting, they are easy to mold, lightweight, and convenient to carry.
The thickness of the material used for the packaging container 1 is determined in consideration of the strength required for the packaging container 1.

The length L5 of the packaging container 1, that is, the length of the boundary 12 between the first surface portion 10 and the third surface portion 30 is determined in accordance with the size of the article to be packaged.
The height H of the packaging container 1, that is, the distance from the first surface portion 10 to the ridge line 21 is determined according to the size of the article to be packaged.
The width of the packaging container 1, that is, the length L1 from the boundary 12 with the third surface portion 30 to the boundary 14 with the fourth surface portion 40 in the first surface portion 10 depends on the size of the object to be packaged, etc. It is determined.

The length L1 from the boundary 12 with the third surface portion 30 to the boundary 14 with the fourth surface portion 40 in the first surface portion 10 is the fourth from the boundary 22 with the third surface portion 30 in the second surface portion 20. The length L2 to the boundary 24 with the surface portion 40 is shorter than the length L2. The length L2 is the distance from the boundary 22 to the boundary 24 in the second surface portion 20, and is the total of the length L2a from the boundary 22 to the ridge line 21 and the length L2b from the boundary 24 to the ridge line 21.
The difference between the length L1 and the length L2 is determined in consideration of the size of the packaging container 1 and the design properties. For example, 15% or less of the length L4 is preferable, and 5% or less is more preferable.
For example, if the length L1 is 50 to 300 mm, the difference between the length L1 and the length L2 is preferably 0.3 to 20 mm, more preferably 1 to 8 mm.
If it is less than the above lower limit value, the ridge line 21 may not be noticeable, and if it exceeds the above upper limit value, the difference between the length L3 and the length L4 becomes large, and the design may be impaired.

The length L3 from the boundary 12 with the first surface portion 10 to the boundary 22 with the second surface portion in the third surface portion 30 is the second length L3 from the boundary 14 with the first surface portion 10 in the fourth surface portion 40. The length to the boundary 24 with the surface portion 20 is shorter than the length L4.
The difference between the length L3 and the length L4 is equal to the difference between the length L1 and the length L2.
Thus, the sum of the length L1 and the length L4 is made equal to the sum of the length L2 and the length L3. By making the sum of the length L1 and the length L4 equal to the sum of the length L2 and the length L3, the sachet packaging material constituting the packaging container 1 can be normally folded. “Normally fold” means that when folding a sack-wrapping packaging material, the two surfaces are opposed to each other and folded without forming a new fold line.

The manufacturing method of the packaging container 1 is demonstrated using FIGS.
FIG. 3 is a plan view of the blank 4 constituting the packaging container 1, and FIG. 4 is a schematic view of a sack-attached packaging material 4 a obtained by sack-attaching the blank 4.
First, a sheet-like material of an arbitrary material is punched to obtain a blank 4 shown in FIG.
The blank 4 includes a first surface portion 10 having a rectangular shape in plan view with one side as a long side, a third surface portion 30 having a rectangular shape in plan view extending on one side forming the length of the first surface portion 10, A fourth surface portion 40 in a plan view rectangle extending on the other side forming the length of one surface portion 10, and a plan view rectangle extending in the fourth surface portion 40 on the opposite side of the first surface portion 10. 2nd surface part 20 is provided.

A crease line 12 a is formed at the boundary between the first surface portion 10 and the third surface portion 30, and a crease line 14 a is formed at the boundary between the first surface portion 10 and the fourth surface portion 40. A crease line 24 a is formed at the boundary between the fourth surface portion 40 and the second surface portion 20.
The second surface portion 20 has a longitudinal direction along the crease line 24a, and a ridge line rule line 21a is formed on the second surface portion 20 along the crease line 24a.

The third surface portion 30 has a longitudinal direction along the crease line 12a, and the fourth surface portion 40 has a longitudinal direction along the crease line 14a.
The third surface portion 30 has a fifth surface portion 50 extending at one end in the longitudinal direction and a sixth surface portion 60 extending at the other end in the longitudinal direction.
On the side opposite to the first surface portion 10, the third surface portion 30 is provided with a handle paste 70 b, a handle portion 70, and a handle paste 70 a in this order, and the third surface portion 30 and the handle paste 70 b. A crease line 22a is formed at the boundary.

On the first surface portion 10, a flap 10a is extended at one end in the longitudinal direction, and a flap 10b is extended at the other end in the longitudinal direction.
The second surface portion 20 has a flap 20c extending at one end in the longitudinal direction and a flap 20d extending at the other end in the longitudinal direction.
The fourth surface portion 40 has a flap 40a extending at one end in the longitudinal direction and a flap 40b extending at the other end in the longitudinal direction.

Next, let the obtained blank 4 be the sack pasting packaging material 4a. The sack pasting packaging material 4a is obtained by the following method.
First, the blank 4 is bent by folding the crease line 12a and the crease line 24a in a mountain. At this time, the blank 4 is bent by aligning the edge 23 opposite to the crease line 24a in the second surface portion 20 and the crease line 22a.
The handle 70 is folded in a crease at the crease line 71, and the boundary between the handle 70 and the handle paste 70a and the boundary between the handle 70 and the handle paste 70b are folded in a valley. A handle sticking margin 70a is adhered to the region 20a between the ridge line ruled line 21a and the crease line 24a in the second surface part 20, and the region 20b between the ridge line ruled line 21a and the end side 23 in the second surface part 20 is adhered. The handle sticking margin 70b is adhered to obtain the sack pasting packaging material 4a.

 As shown in FIG. 4, since the total of the length L1 and the length L4 is equal to the sum of the length L2 and the length L3, the obtained sack pasting packaging material 4a has the first surface portion 10 and the first surface portion 10a. The surface in which the four surface portions 40 are connected to the same surface and the surface in which the second surface portion 20 and the third surface portion 30 are connected to the same surface are opposed to and in contact with each other.

A method of assembling the packaging container 1 using the sack pasting packaging material 4a will be described.
While the crease line 12a and the crease line 24a are brought close to each other, the crease lines 14a, 22a and the ridge line rule line 21a are mountain-folded so that the crease lines 14a, 22a and the ridge line rule line 21a protrude outward, and the cylindrical body 2 (FIG. 1) is formed. At this time, the portions bent at the crease lines 12a, 14a, 22a, 24a become the boundaries 12, 14, 22, 24, respectively, and the portions bent at the ridge line rule lines 21a become the ridge lines 21 (FIG. 1).
Next, the flap 10a, the flap 20c, and the flap 40a are folded so as to close one open end of the cylindrical body 2, and the fifth flap 50a is placed on the folded flaps 10a, 20c, 40a and bonded. Further, the flap 10b, the flap 20d, and the flap 40b are folded so as to close the other open end of the cylindrical body 2, and the folded flaps 10b, 20d, 40b are covered with the sixth surface portion 60 and bonded, Container 1 is used.

 In the conventional packaging container, the length L3 of the third surface portion is equal to the length L4 of the fourth surface portion. When a ridge line is formed on the second surface portion (that is, when the length L2 is longer than the length L1), when the blank is folded along the crease lines 12a and 24a, a part of the second surface portion and the third surface portion are formed. A part of the surface part of will overlap. For this reason, it is necessary to distribute the blank as it is without using the sachet packaging material, or to form a new crease line on the third surface portion along the boundary between the third surface portion and the first surface portion, for example. It was. The crease line formed on the third surface portion is a so-called discarded ruled line, which has been a factor that impairs the design and strength of the assembled packaging container.

As above-mentioned, since the ridgeline is formed in the 2nd surface part, the packaging container of this embodiment becomes a side view pentagon, and becomes the thing excellent in the designability.
According to the present embodiment, since the sum of the length L1 and the length L4 is equal to the sum of the length L2 and the length L3, even if L1 <L2, the blank is pasted together and folded normally. It can be distributed as an adhesive packaging material. For this reason, manufacture of a sack pasting packaging material is easy, and assembly operation of a packaging container is easy.
In addition, since the sum of the length L1 and the length L4 is equal to the sum of the length L2 and the length L3, even if the third surface portion and the fourth surface portion are substantially parallel, the second surface portion A ridge line can be formed in the wrapping material and can be distributed as a sack pasting packaging material.
Furthermore, since it is not necessary to form a ruled line, the design of the packaging container is not impaired and the strength of the packaging container is not impaired.

The present invention is not limited to the above-described embodiment.
In the above-described embodiment, the side view is a pentagon, and the side view shape of the second surface portion is a triangle having a ridge line as a vertex, and the fifth surface portion and the sixth surface portion having a shape corresponding thereto are provided. However, the present invention is not limited to this.
For example, like the packaging container 100 shown in FIG. 5, the 6th surface part 160 and the 5th surface part of the shape corresponding to this form the ridgeline by bulging the 2nd surface part 120 circularly in side view. May be provided. Alternatively, like the packaging container 200 shown in FIG. 6, the second surface portion 220 may be trapezoidal in a side view, and the sixth surface portion 260 and the fifth surface portion having a shape corresponding thereto may be provided. In the side view, the second surface portion may be a polygon other than a triangle or a trapezoid.

 In the above-described embodiment, the ridge line is formed at a position that bisects the length from the boundary with the third surface portion to the boundary with the fourth surface portion in the second surface portion, but the present invention is limited to this. Instead, the ridgeline may be formed near the boundary between the second surface portion and the third surface portion, or may be formed near the boundary between the second surface portion and the fourth surface portion.

 In the above-described embodiment, the third surface portion and the fourth surface portion are substantially parallel, but the present invention is not limited to this, and the third surface portion and the fourth surface portion are the second surface portion. It may be closer as it goes, or it may be farther away. However, the third surface portion and the fourth surface portion are preferably substantially parallel. If the third surface portion and the fourth surface portion are substantially parallel, a plurality of packaging containers are aligned and packed in the outer box, so that they can be transported and stored efficiently.

 In the above-described embodiment, the handle portion is provided on the second surface portion, but the present invention is not limited to this, and the handle portion may be provided on any of the third to sixth surface portions. However, the handle portion may not be provided.

 In the above-described embodiment, the second surface portion is the top surface, but the present invention is not limited to this, and any of the first to sixth surface portions may be the top surface. However, if the contents are leaked from the packaged items when stored and distributed in the upside down direction, the second surface portion is preferably the top surface. Since the ridgeline is formed on the second surface part, the posture of the packaging container is not stable even if trying to place the second surface part vertically downward, and the user can recognize that the packaging container is upside down. It is.

In the above-described embodiment, the first surface portion is a rectangle whose length is the boundary with the third surface portion, but the present invention is limited to this, and the boundary with the third surface portion is short. It may be a thing or a square.
In the above-described embodiment, the second surface portion is a rectangle having a boundary with the third surface portion as a longitudinal direction, but the present invention is not limited to this, and the second surface portion is the third surface portion.

The boundary may be short or square.
In the above-described embodiment, the fourth surface portion is a rectangle having a boundary with the first surface portion as a longitudinal direction, but the present invention is not limited to this, and the fourth surface portion is the first surface portion. The boundary may be short or square.
In the above-described embodiment, the fifth surface portion is shaped to have a short boundary with the first surface portion, but the present invention is not limited to this, and the fifth surface portion is the first surface portion. The boundary may be a long side or a square.
In the above-described embodiment, the sixth surface portion is shaped to have a short boundary with the first surface portion, but the present invention is not limited to this, and the sixth surface portion is the first surface portion. The boundary may be a long side or a square.
The first to sixth surface portions may be appropriately designed according to the shape, quantity, etc. of the package within a range satisfying L1 <L2, L1 + L4 = L2 + L3.

In the above-described embodiment, the flap and the fifth surface portion or the sixth surface portion are bonded to each other in assembling the sachet packaging material into the packaging container, but the present invention is not limited to this. For example, the insertion piece is extended to the fifth surface portion and the sixth surface portion, and this is inserted into the insertion port formed at the boundary between each flap and the first to second surface portions or the fourth surface portion. A packaging container may be assembled.
Alternatively, an insertion piece is formed on each flap, and the insertion piece is formed at the boundary between the third surface portion and the fifth surface portion, the boundary between the third surface portion and the sixth surface portion, or the like. The packaging container may be assembled by inserting it into the mouth.

 Examples of the packaging container of the present invention will be described below, but the present invention is not limited thereto.

Example 1
A blank similar to the blank 4 shown in FIG. 3 was produced using paperboard (weight per unit: 550 g / m ² ). This blank has a height H = 203 mm, a length L5 = 262 mm, a length L1 = 89 mm, a length L2 = 92 mm, a length L3 = 190 mm, and a length L4 = 193 mm in the packaging container 1 of FIG. Molded.
Using the obtained blank, a sack pasting packaging material was produced in the same manner as the sack pasting packaging material 4a in FIG. The obtained sack pasting packaging material was normally folded, and when assembled, the packaging container was easily assembled. In addition, the assembled packaging container had a good appearance.

(Comparative Example 1)
A blank is formed in the same manner as in Example 1 except that the length from the boundary with the first surface portion to the boundary with the second surface portion is 193 mm (that is, L3 = L4, L1 + L4 <L2 + L3). Got. Using the obtained blank, an attempt was made to produce a sachet wrapping material similar to the sack paste wrapping material 4a of FIG. 4, and as shown in FIG. The crease line 22a formed at the boundary with the third surface portion 830 is mountain-folded, and the first surface portion 10 and the fourth surface portion 40 are lifted from the surface that is flush with the first surface portion 10 and cannot be normally folded.

(Comparative Example 2)
A blank was manufactured in the same manner as in Comparative Example 1 except that the crease line 904 along the crease line 12a was formed on the third surface portion 930 as in the blank 900 shown in FIG. This blank becomes a packaging container of L3 = L4 and L1 + L4 <L2 + L3. The distance between the crease line 12a and the crease line 904 was 2 mm.
Using the obtained blank 900, a sack pasting packaging material similar to the sack pasting packaging material 902 shown in FIG. 9 was produced, and the sack pasting device could be easily produced. In addition, when the obtained sack pasting packaging material was assembled, it was easily assembled.
However, the crease line 904 formed on the third surface portion 930 impairs the design of the packaging container. In addition, the crease line 904 is fragile.

 From these results, it was found that by applying the present invention, it is possible to provide a packaging container that is excellent in design properties, easy in assembly operation, and can be manufactured by a general-purpose sack pasting machine without impairing strength.
