Description

The present invention relates to a packaging container for storing contents and a method for using the packaging container, and in particular to a packaging container made of environmentally friendly materials and a method for using the packaging container.

Conventionally, products aimed at removing odors or dispersing odors and fragrances, such as deodorants, insect repellents, and air fresheners, have been sold. Because these products require a moderate level of airtightness and breathability, the containers in which they are stored are often made of plastic, which is easy to process (see Patent Document 1).

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
<Packaging Container Composition>
Fig. 1 is a perspective view of a packaging container according to one embodiment of the present invention. Fig. 2 is a front view and a back view of the packaging container according to one embodiment of the present invention. Fig. 3 is a top view and a bottom view of the packaging container according to one embodiment of the present invention. In Fig. 3, Fig. 3(a) is a top view of the initial state, Fig. 3(b) is a top view of a state in which the cover plate has been separated, and Fig. 3(c) is a bottom view. Fig. 4 is a development view of the packaging container according to one embodiment of the present invention.

As shown in Figures 1 to 3, a packaging container 1 according to one embodiment of the present invention is a roughly rectangular box shape surrounded by a front panel 2a, a back panel 2b, side panels 5a and 5b, a cover panel 3a, and a bottom panel 4. Of these, the side panels 5a and 5b are identical rectangular shapes. As shown in Figure 3(a), on the top side, the cover panel 3a is visible, but the top panel 3b is overlapped on the inside (below) of the cover panel 3a. Also, on the bottom side, the bottom outer panel 4a and the bottom inner panel 4b are overlapped to form the bottom panel 4.

As shown in FIG. 2, the front panel 2a and the back panel 2b have the same shape, and the edges of the side where they are connected to the side panels 5a and 5b (the left and right sides in FIG. 2) are straight, but the edges of the side where they are connected to the cover panel 3a and the top panel 3b (the upper side in FIG. 2) are curved and convex downward, and the edges of the side where they are connected to the bottom panel 4 (the lower side in FIG. 2) are curved and convex upward. That is, the boundary between the front panel 2a and the back panel 2b and the top panel 3b and the bottom panel 4 is convex toward the front panel 2a and the back panel 2b. In the front panel 2a and the back panel 2b, the edges of the side where they are connected to the bottom panel 4 (the lower side in FIG. 2) are curved and convex upward, so that if they are left as they are, the lower ends will only have two points, the left and right ends, and will be unstable when placed. Therefore, a support piece 11a is connected to the lower edge of the front panel 2a, and a support piece 11b is connected to the lower edge of the back panel 2b. That is, the front panel 2a and the back panel 2b each have support pieces 11a and 11b that protrude toward the bottom panel 4. The support pieces 11a and 11b increase stability when the packaging container 1 is placed with the top panel 3b facing upward.

The front panel 2a and rear panel 2b have a large opening window 21 and three small opening windows 22-24, and are surfaces that can adjust ventilation and have the largest area of all the surfaces that make up the storage section. For ease of explanation, the front panel 2a and rear panel 2b are described separately in this specification, but either can be the front or the rear. Since either can be the front, hereafter the front panel 2a and rear panel 2b may be collectively referred to as the front panel 2. The front panel 2a and rear panel 2b are a pair of front panels that face each other.

As shown in Figure 3, the cover plate 3a, top plate 3b, and bottom outer plate 4a are of the same shape, and the edges on the sides where they connect to the side plates 5a, 5b (the left and right sides in Figure 2) are straight, but the edges on the sides where they connect to the front plate 2a and back plate 2b (the upper and lower sides in Figure 3) are curved and convex outward. Because the edges of the cover plate 3a and bottom plate 4 where they connect to the front plate 2a and back plate 2b are curved and convex outward, the front plate 2a and back plate 2b are convex outward, making it easier to store contents that have curved sides as well as cubic or rectangular contents.

As shown in FIG. 2(a), the front panel 2a has one large opening window 21a and three small opening windows 22a, 23a, and 24a. As shown in FIG. 2(b), the rear panel 2b has one large opening window 21b and three small opening windows 22b, 23b, and 24b. The large opening window 21a of the front panel 2a and the large opening window 21b of the rear panel 2b are provided in positions facing each other and have symmetrical shapes. In this embodiment, the large opening window 21a and the large opening window 21b are approximately rectangular, although the four corners are arc-shaped. The small opening windows 22a, 23a, and 24a of the front panel 2a and the small opening windows 22b, 23b, and 24b of the rear panel 2b are also provided in positions facing each other and have symmetrical shapes. In this embodiment, the small opening window 22a and the small opening window 22b are trapezoidal with arc-shaped corners, a horizontal bottom edge, and a height that increases toward the side panel 5a. The small opening window 23a and the small opening window 23b are generally rectangular, although the corners are arc-shaped. The small opening window 24a and the small opening window 24b are trapezoidal with arc-shaped corners, a horizontal top edge, and a height that increases toward the side panel 5a. The large opening window and the small opening window that face each other perform the same function, so hereinafter, the large opening window 21a and the large opening window 21b are collectively referred to as the large opening window 21, and the small opening windows 22a, 23a, and 24a and the small opening windows 22b, 23b, and 24b are collectively referred to as the small opening windows 22, 23, and 24.

The "large" and "small" relationship between the large opening window portion and the small opening window portion is relative. In this embodiment, as shown in Figures 2 and 4, the large opening window portion 21 has an area three or more times that of each of the small opening windows 22 to 24. For this reason, the opening windows having an area smaller than the large opening window portion 21 are defined as the small opening windows 22 to 24. The small opening windows 22 to 24 do not necessarily have the same area. In this embodiment, as shown in Figures 2 and 4, the small opening window portion 23 is slightly smaller than the small opening windows 22 and 24. However, since the area ratio is less than 20%, here, the small opening windows 22 to 24 are treated as small opening windows equally. In fact, if the area ratio is within about twice, they can be treated as small opening windows.

As shown in FIG. 2, the large opening window 21 is provided on one side panel 5b, and the small opening windows 22-24 are provided on the other side panel 5a in order to accommodate the characteristics of the contents. For example, if the contents are deodorants, some should be exposed to air over a wide area from the large opening, and some should be exposed to air only partially from the small opening, depending on their characteristics. In this case, the contents that should be exposed to air over a wide area are stored in the position corresponding to the large opening window 21, and the contents that should be exposed to air only partially are stored in the positions corresponding to the small opening windows 22-24.

The packaging container 1 according to this embodiment is made of paper and is produced by folding and gluing a single blank (see FIG. 4). The large opening window 21 and the small opening window sections 22-24 are surrounded by a planned cutting line so that the user can open them manually. As shown in FIG. 2, the planned cutting line is the boundary line between the large opening window 21 and the small opening window sections 22-24, in which cut sections and non-cut sections are arranged alternately. Therefore, the large opening window section 21 and the small opening window sections 22-24 are surrounded on all sides by intermittent cuts (cut sections). The large opening window section 21 and the small opening window sections 22-24 are connected to the front panel 2a and the back panel 2b by the non-cut sections.

The length of the non-cut portions of the large opening window 21 is approximately 0.2 to 0.5 mm in the direction along the periphery of the large opening window 21. The length of the cut portions of the large opening window 21 is approximately 12 to 13 mm in the straight line portions, and approximately 20 mm including the arc portions at the four corners. The non-cut portions are evenly arranged on the four sides of the large opening window 21. Because the length of the non-cut portions is very short compared to the length of the cut portions, the non-cut portions can be easily broken by applying force to the large opening window 21. Therefore, the large opening window 21 can be easily separated by hand to form openings in the front panel 2a and back panel 2b.

An opening, end hole 25a, is formed at the upper left end of the large opening window 21a on the front panel 2a, and an opening, end hole 25b, is formed at the upper right end of the large opening window 21b on the back panel 2b. The end holes 25a and 25b are formed in positions facing each other. In other words, when there is no content inside and you look straight through the end hole 25a, you can see the outside on the other side through the end hole 25b. The end holes 25a and 25b are openings that make it easy to separate the large opening window 21a and the large opening window 21b. The user can easily break the non-cut portion by inserting their fingers into the end holes 25a and 25b and pushing the large opening window 21a and the large opening window 21b from the inside to the outside.

Unlike the large opening window 21, the small opening window 22-24 is not necessarily intended to be separated. Therefore, the relationship between the cut and non-cut portions is different from that of the large opening window 21. As shown in Figures 2 and 4, in the large opening window 21, the non-cut portions are evenly arranged on the four sides, but in the small opening window 22-24, no non-cut portions are formed on the upper side, one non-cut portion is formed on each of the left and right sides, and three non-cut portions are formed on the lower side. The upper side is all cut portions, and is separated from the main body of the front panel 2 (front panel 2a, rear panel 2b). The length of the non-cut portions on the left and right sides is about 0.2 to 0.5 mm in the direction along the periphery of the small opening window 22-24, just like the large opening window 21. The length of the non-cut portion on the lower side is approximately 1.7 to 2.3 mm in the direction along the periphery of the small opening window portions 22 to 24. On the left and right sides of the small opening window portions 22 to 24, the length of the non-cut portion is very short compared to the length of the cut portion, so the non-cut portion can be easily broken by applying force to the large opening window portion 21. On the other hand, on the lower sides of the small opening window portions 22 to 24, the non-cut portion is relatively long, so it is more difficult to break than the non-cut portions on the left and right sides.

Since the small opening windows 22-24 are configured in this way, when the upper part of the small opening windows 22-24 is pressed from the outside, the cut parts on the left and right sides are broken and the small opening windows 22-24 are pushed inward as is. When pressed normally, the non-cut part on the lower side is not broken and remains. Since the non-cut part on the lower side is about 1.7-2.3 mm, if necessary, the non-cut part can be broken by gripping the small opening windows 22-24 and applying a pulling force to separate the small opening windows 22-24. When a user purchases a product contained in such a packaging container, seeing that the upper side of the small opening windows 22-24 has no non-cut part and is entirely cut, the user will naturally press the upper part. In other words, the shape of the small opening windows 22-24, with the entire upper side cut, can guide the user to the position where to press.

As shown in Figures 2 and 4, the front panel 2a and the back panel 2b each have a single large opening window 21a, 21b arranged vertically, and multiple small opening windows 22a-24a, 22b-24b arranged vertically. In this way, by having a large opening window 21 that does not overlap vertically and multiple small opening windows 22-24 arranged vertically, the user can adjust the size and position of the opening to be made by themselves.

As shown in FIG. 2(b), a semicircular front opening 14b is formed in the center of the upper edge of the back panel 2b. A notch 15 is formed along the upper edge of the front opening 14b. As will be described later, the notch 15 is an insertion port into which the top insertion piece 10a, which is continuous with the cover plate 3a, is inserted. The front opening 14b is an opening for placing the fingertip on the top insertion piece 10a, and when opening the package, the fingertip is inserted through the front opening 14b and the top insertion piece 10a is removed from the insertion port formed by the notch 15.

3 is a top view and a bottom view of the packaging container according to this embodiment. Of these, FIG. 3(a) is a top view of the packaging container 1 before the lid plate 3a is separated, FIG. 3(b) is a top view of the packaging container 1 after the lid plate 3a is separated, and FIG. 3(c) is a bottom view of the packaging container 1. As shown in FIG. 3(a), in the initial state, the lid plate 3a is stacked on the top plate 3b, so that the lid plate 3a can be seen from the top. In this state, when the lid plate 3a is separated from the front plate 2a along the separation line 13, the top plate 3b appears as shown in FIG. 3(b). The top plate 3b has a top opening 14a that is an opening leading to the storage section. In this embodiment, the top opening 14a is a circular through hole, and five of them are formed with the same size. For example, when the contents are deodorant, the top opening 14a appears by cutting off the lid plate 3a at the time of use. The top opening 14a allows ventilation, allowing air to enter from outside, so that the air that comes into contact with the deodorant is deodorized.

4 is a development view of the packaging container according to the present embodiment. It is also a view showing a packaging sheet 1A for creating a packaging container. The packaging sheet 1A is a blank for creating a packaging container, and in this embodiment, it is a paper packaging backing. As the paper used as the packaging sheet 1A, any paper can be adopted taking into consideration the characteristics of the contents and the strength and durability. It is preferable that the packaging sheet 1A has a certain thickness, and the basis weight is preferably 200 g/m ² or more and 450 g/m ² or less, particularly 300 g/m ² or more and 400 g/m ² or less. In this embodiment, coated paper with a basis weight of 350 g/m ² is adopted.

In this embodiment, the up-down direction in FIG. 4 is parallel to the grain of the paper. As shown in FIG. 4, in the packaging sheet 1A, the side panel 5a, the front panel 2a, the side panel 5b, the back panel 2b, and the adhesive strip 12 are connected in a direction intersecting the grain of the paper. Since folding is performed between each panel and each panel, in this embodiment, creases are formed as intended fold lines. The width (thickness) of the crease can also be set arbitrarily, but in this embodiment, it is set to 0.70 mm. In FIG. 4, the intended fold lines are indicated by dashed lines.

As shown in FIG. 4, in the packaging sheet 1A, the top insertion piece 10a, the cover plate 3a, the front plate 2a, the bottom outer plate 4a, and the bottom insertion piece 10b are connected in a direction parallel to the grain of the paper. The cover plate 3a and the front plate 2a are connected via a planned separation line 13. In this embodiment, the planned separation line 13 is formed as a perforation in which cut portions and non-cut portions are arranged alternately. Since folding is performed between each of the other plates and pieces, in this embodiment, a pressed crease is formed as the planned folding line.

A cut is made near the boundary between the front panel 2a and the bottom outer panel 4a to form the support piece 11a. This cut corresponds to the cuts on the three sides other than the upper base of a trapezoid whose upper base is longer than the lower base. Due to the presence of this cut, when folding is performed along the planned folding line between the front panel 2a and the bottom outer panel 4a, the support piece 11a is separated from the bottom outer panel 4a as a piece that extends parallel to the surface of the front panel 2a. The front panel 2a and the back panel 2b each have support pieces 11a and 11b that protrude toward the bottom panel 4.

As shown in FIG. 4, in the packaging sheet 1A, the front flap 9, the top panel 3b, the back panel 2b, and the bottom inner panel 4b are connected in a direction parallel to the grain of the paper. Since folding is performed between each panel and piece, in this embodiment, creases are formed as the intended fold lines. A cut 15 is formed between the top panel 3b and the back panel 2b along the intended fold line. This cut 15 functions as a top insertion port for inserting the top insertion piece 10a.

A cut is made near the boundary between the back panel 2b and the bottom inner panel 4b to form a support piece 11b similar to the support piece 11a near the boundary between the front panel 2a and the bottom outer panel 4a. Like the cut that forms the support piece 11a, this cut corresponds to the cuts on the three sides other than the upper base of a trapezoid whose upper base is longer than the lower base. Due to the presence of this cut, when folding is performed along the planned folding line between the back panel 2b and the bottom inner panel 4b, the support piece 11b is separated from the bottom inner panel 4b as a piece that extends parallel to the surface of the back panel 2b.

The bottom flap 7a and top flap 8a are connected to the side panel 5a, and the bottom flap 7b and top flap 8b are connected to the side panel 5b. Since folding is performed at these connecting portions, in this embodiment, creases are formed as intended fold lines. On the surface of the packaging sheet 1A shown in FIG. 4 that will be the outer surface when assembled into the packaging container 1, any information such as product information or instructions on how to use the packaging container can be printed.

<Manufacturing of Packaging Containers>
When manufacturing a packaging container, the cardboard is processed to have separation lines, cutting lines (boundary lines), fold lines, etc., and then punched out into a blank shape by punching. As a result, a packaging sheet 1A as shown in FIG. 4 is obtained. Next, the packaging sheet 1A as shown in FIG. 4 is folded appropriately along each fold line. In addition, adhesive is applied to the glue strip 12, which is then bonded to the side plate 5a to form a cylindrical body. Then, on the bottom side (lower side in FIG. 4), the bottom outer plate 4a covers the bottom inner plate 4b, and the bottom insertion piece 10b is inserted into the insertion opening formed by the cut surrounding the support piece 11b. With the bottom outer plate 4a and the bottom inner plate 4b overlapping to form the bottom plate 4, the contents are inserted from the opening on the top side and stored. Then, on the top side (upper side in FIG. 4), the front flap 9 is placed against the inner surface of the front panel 2a, and the top insert piece 10a is inserted into the notch 15 so that the cover plate 3a covers the top panel 3b. This completes the packaging container 1 with the contents contained therein. The packaging container 1 can be further shrink-wrapped to cover the entire container. In this case, the shrink-wrap itself may be printed. As described above, if the outer surface of the packaging container 1 is directly printed, it is preferable that the shrink-wrap be transparent.

<Contents>
The contents may be any contents, whether food or non-food. The contents may be solid, liquid, powder, granular, gel, etc., but in the case of liquid, powder, granular, gel, etc., they must be individually packaged. Since one of the features of the packaging container according to the present embodiment is that it is possible to control ventilation, the contents are preferably powder, granular, or gel-like contents individually packaged in a breathable manner, or solid contents.

As an example, in the case of a deodorant, a molded container containing deodorant gel is placed in the area between the large opening window 21a and the large opening window 21b. The top of the molded container is sealed with a film, and when in use, this seal is peeled off to expose the deodorant gel. This is because the deodorant gel has a higher deodorant effect when it is exposed to air over a wide area from the large opening. Also, a paper pillow bag containing activated carbon is placed in the area between the small opening window 22a-24a and the small opening window 22b-24b. The paper pillow bag allows air to pass through between its paper fibers. This is because the activated carbon has a higher deodorant effect when it is partially exposed to air from the small opening.

<How to use>
Next, a method of using the packaging container 1 as shown in FIG. 1 will be described. First, if the packaging container 1 is shrink-wrapped, break the shrink-wrap to take out the packaging container 1. Next, insert your fingertip into the front opening 14b formed in the upper center of the back panel 2b on the top side of the packaging container 1, and move the top insertion piece 10a upward to remove it from the notch 15. FIG. 5 is a perspective view showing the state in which the top insertion piece 10a has been removed from the notch 15. FIG. 5 shows the state in which the cover plate 3a is further erected after the top insertion piece 10a has been removed from the notch 15. Note that FIG. 1 is a perspective view from the front side, whereas FIG. 5 is a perspective view from the back side. Therefore, in FIG. 5, the back panel 2b is located on the near side. When the top insertion piece 10a is removed from the notch 15 and the cover plate 3a is erected, the top panel 3b having a plurality of top openings 14a is exposed.

Next, in the state shown in FIG. 5, the body side of the packaging container 1 is held down, the cover plate 3a is grasped, and the separation line 13 is cut. This separates the cover plate 3a from the body. When the cover plate 3a is separated from the body, the top plate 3b remains exposed. This allows air to flow in and out through the multiple top openings 14a. If a deodorant is contained as a content, the deodorization will proceed.

In this state, the fingertip is inserted through the end hole 25a formed in the front panel 2a and the large opening window 21a is pulled outward. Figure 6 is a perspective view showing the state in which the cover plate 3a has been separated from the main body, and the fingertip is inserted through the end hole 25a to pull the large opening window 21a. Note that Figure 6 is a perspective view seen from the front side, similar to Figure 1. Therefore, in Figure 6, the front panel 2a is located on the near side. From the state shown in Figure 6, the large opening window 21a is further pulled and separated, forming a large opening in the front panel 2a.

Then, the upper parts of the small opening windows 22a to 24a on the front panel 2a are further pushed in. This widens the three small openings. Figure 7 is a perspective view showing the state in which the upper part of the small opening window 22a is pushed in after the large opening window 21a has been separated, widening the opening corresponding to the small opening window 22a. Figure 7 is a perspective view seen from the front side, similar to Figures 1 and 6. Therefore, in Figure 7, the front panel 2a is located on the near side.

Then, push in the upper parts of the small opening windows 22a to 24a to widen the corresponding small openings. Similarly, on the back panel 2b side, insert your fingertip through the end hole 25b formed in the back panel 2b in the same manner as on the front panel 2a side, and pull the large opening window 21b outward to separate it. Then, push in the upper parts of each of the small opening windows 22b to 24b on the back panel 2b to widen the three small openings.

Figure 8 is a perspective view showing the state in which the large opening window 21a and the large opening window 21b have been separated and the openings corresponding to the small opening windows 22a-24a and the small opening windows 22b-24b have been widened. Like Figures 1, 6, and 7, Figure 8 is a perspective view seen from the front side. Therefore, in Figure 8, the front panel 2a is located on the front side. In order to clarify the structure of the packaging container 1, Figure 8 shows an empty state in which no contents are contained.

As shown in FIG. 8, large openings corresponding to the large opening window 21a and the large opening window 21b, and small openings corresponding to the small opening window 22a-24a and the small opening window 22b-24b are formed, and the top panel 3b has a plurality of top openings 14a formed. The container is then placed in a location to be deodorized, such as inside a refrigerator. Air then flows in through each opening, and the air is deodorized by the deodorizer inside the packaging container 1.

In the above-mentioned method of use, the cover plate 3a is first separated to expose the top plate, and then the large opening window 21 and the small opening window 22-24 are separated to form openings in the front plate 2a and the back plate 2b. However, the large opening window 21 and the small opening window 22-24 may be separated first to form openings in the front plate 2a and the back plate 2b, and then the cover plate 3a may be separated to expose the top plate. Also, some of the large opening window 21 and the small opening window 22-24 may be separated first, and then the cover plate 3a may be separated to expose the top plate, and the remaining large opening window 21 and the small opening window 22-24 may be separated to form openings in the front plate 2a and the back plate 2b. Also, the large opening window 21 and the small opening window 22-24 may not necessarily be separated in their entirety, but only some of them may be separated.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and various modifications are possible. For example, in the above embodiment, three small opening window portions are formed in each front panel (front panel, rear panel), but the number is arbitrary, and one or two may be formed, or four or more may be formed.

In the above embodiment, a relatively large large opening window and a small opening window smaller than the large opening window are formed as the opening window portions in the front panel (front panel, rear panel), but multiple opening window portions of approximately the same area may be provided without any particular distinction in size. Also, each front panel (front panel, rear panel) may be provided with only one opening window portion regardless of the size of the area.

In the above embodiment, the same number and shape of large opening window portions and small opening window portions are formed in one front panel and the other front panel (front panel and rear panel), but the number and shape of the large opening window portions and small opening window portions may be different in one front panel and the other front panel. Also, opening window portions may be formed only in one front panel (front panel, rear panel), and opening window portions may not be formed in the other front panel (front panel, rear panel). Overall, the shape and number of opening window portions formed in the front panels (front panel and rear panel), and whether they are formed in both front panels or only in one front panel, can be appropriately changed depending on the characteristics, efficacy, duration, etc. of the contents such as deodorant, etc.

In the above embodiment, the support pieces are formed so as to be continuous with the lower part of the front panel (front panel, rear panel), but it is not necessary to provide the support pieces. If the support pieces are not provided, the stability will be lower than if the support pieces are provided, but the boundary parts that meet the lower ends of both sides will allow the unit to stand on its own.

In addition, in the above embodiment, the boundary between the front plate and the top and bottom plates is convex toward the front plate, i.e., convex from the top and bottom plate sides, so support pieces are provided for stability when placed, but the boundary between the front plate and the top and bottom plates may be linear. In this case, the front plate and the top and bottom plates are both approximately rectangular. If the front plate and the top and bottom plates are both rectangular, the bottom plate can be placed stably, so support pieces are not necessary.
