Description

Technical Field

[0001] The present invention relates to a product storage box, and more particularly to a product storage box having a cubic shape capable of storing an object therein and being opened by cutting along a linear weak portion provided at the upper part.

Background Art

[0002] A box for storing products is an important member that protects products during the distribution process and conveys various information to customers through the design and display content of the box. Such a product storage box generally has a substantially cubic shape having an upper surface portion, a bottom surface portion, a front surface portion, a back surface portion, and side surface portions on both sides. Various methods are adopted for the opening operation of the box when taking out the product.

[0003] For example, in the case of a box sized relatively small and portable with one hand, a perforation line is provided at an upper position for easy opening. A simple hinge-type opening method is known in which the box wall is divided along the line and the remaining part is used as a hinge for the opening operation. Such boxes typically include a paper storage box for relatively expensive health drinks.

[0004] When such a box with a simple hinge-type opening is opened, the upper part of the product such as the health drink stored therein appears, making it easy to take out in that state, and also creating a sense of luxury in the design when opened.

[0005] In the above conventional upper-opening type product storage box, perforations are horizontally provided as weak portions at a predetermined height position on the front surface portion of the box body, and perforations of inclined lines are formed linearly from both side ends of the perforation line obliquely upward to the corner portion on the back side of the upper end of the box body, respectively, continuously on the side surface portions on both sides. By pressing these perforations, they can be divided, and the upper part of the box body can be rotated and opened with the back surface portion, which is the remaining part, as a hinge portion. That is, a hinge-type rotation opening type is used.

Summary of the Invention

Problems to be Solved by the Invention

[0007] After the product is taken out of the product storage box, it is usually not used again to store the product and is discarded. Generally, when discarding the box body, regardless of its size, it is desirable to discard it after folding it as small as possible in order to suppress the amount of garbage. Therefore, after taking out the product, the product purchaser usually folds or crushes the box by hand and discards it.

[0008] However, in the case of the above-mentioned conventional hinge-type open product storage box, especially in the case where not only the upper surface part of the box body is opened and closed, but the box is divided along the perforations of the inclined lines provided on both sides of the box, and the side parts and a part of the front part are both opened. In the case of the above-mentioned hinge-type opening method, the part that rotates is not in a planar form, but is maintained in a firm three-dimensional shape. Therefore, it cannot be easily folded, and it is necessary to break or crush it using both hands, which is troublesome, and it is usually discarded in a bulky state.

[0009] Patent Document 1 relates to a "packing box" and discloses a configuration for facilitating folding during disposal and facilitating the opening operation of the lid. However, the opening and closing of the box targeted here is not a method in which a part of the side rotates while remaining in a box shape (three-dimensional shape) at the same time, but only the flat lid is opened and closed. Therefore, it cannot be applied to facilitating the opening and folding operations of a product storage box that simultaneously opens the upper surface part and a part of both side parts.

[0010] In addition, Patent Document 2 relates to a "packaging box" and discloses a configuration for facilitating the opening operation and disposal operation of a packaging box body. However, similar to Patent Document 1, the opening method of the target box body is not one in which a part of the front part and a part of both side parts are opened simultaneously, and thus it cannot be applied to the box body targeted by the present invention.

[0011] The present invention has been made in view of the above problems, and its object is to provide a commodity storage box having a cubic box body, in which at least a part of the front part and a part of both side parts, which are pressed and divided along a linear weak part, are simultaneously rotated and opened, thereby facilitating folding and opening when the commodity storage box is discarded.

Means for Solving the Problems

[0012] In order to achieve the above object, the commodity storage box according to claim 1 is a box body having a cubic shape that can store an object inside and includes an upper surface part, a bottom surface part, a front part, a back part, and both side surface parts, both side weak parts, which are formed on each of the both side surface parts and are perforated cutting lines formed at a predetermined interval so as to extend obliquely downward from the uppermost part on the back part side or a position near it toward the front part side, and a front weak part, which is formed on the front part and is a perforated cutting line formed at a predetermined interval so as to connect the lowermost end positions of the linear weak parts on the both side surface parts. In the commodity storage box that is cut along the weak part and the upper part is rotationally opened with the back part as a rotation axis, each of the both side surface parts is provided with an additional weak part, which is a linear weak part extending from the uppermost part on the front part side to the both side weak parts or near it, and the additional weak part is configured as a part having a shape maintaining force weaker than that of the other side surface parts so as to become a bent part after or simultaneously with the both side weak parts and the front weak part being divided when released.

[0013] In this invention, the "weak part" means a part where the shape retention force is weakened so that it can be easily divided or bent by pressing force, and it is realized by, for example, making cut lines at predetermined intervals in a so-called perforated pattern or forming it thinner than other parts.

[0014] According to the configuration of the present invention, the opening of the upper part of the product storage box is performed by applying a pressing force to the box body along the front weak part and the both-side weak parts, so that these parts are broken, and the remaining back part becomes the rotation axis of the upper part of the box, that is, the hinge part. Then, the upper part of the box body in the rotatable state is rotated and opened, and the object (product) stored therein is taken out.

[0015] After that, when folding or crushing the box body for disposal, for the upper part of the box body in the rotatable state, by pushing the upper part of the divided front part from the front side, the part above the both-side weak parts respectively formed on the both-side side faces is bent at the part of the additional weak part and can be easily folded.

[0016] In addition, the additional weak parts provided on the both-side side faces are also bent depending on the way of applying force when the upper part in front of the front weak part is pushed from the front and broken along the both-side weak parts during the first box opening operation. Therefore, the pushing operation is easy during the box opening operation, and the opening operation of the upper part of the box becomes smoother.

[0017] Note that the additional weak part does not need to be completely broken like the both-side weak part and the front weak part, and can be formed by weakening the shape retention force compared to other parts so that it is easy to bend. It is not limited to a perforated cut line, and is formed by making that part thin or weak in a line shape.

[0018] The product storage box according to claim 2 is the product storage box according to claim 1, wherein the linear additional weak part extends from the uppermost part on the front part side to the substantially central position of the both-side weak parts at an inclination angle of approximately 45 degrees with respect to the front part and the upper surface part.

[0019] According to this configuration, the folding of the box portion above the broken front vulnerable portion and both side vulnerable portions is performed with good left - right balance on both side surface portions. That is, since it bends at approximately the central position of both side vulnerable portions where force is likely to concentrate, easiness of folding is also ensured.

[0020] The product storage box according to claim 3 is the product storage box according to any one of claims 1 or 2, wherein the linear both - side vulnerable portions are formed as downwardly convex curved lines. According to this configuration, compared with a conventional straight - line perforation line, facilitation of breakage when performing the first pushing - in operation and facilitation of the breakage operation during the pushing - in breakage operation are achieved.

Effect of the Invention

[0021] According to the product storage box of the present invention, when the product storage box is discarded, it is cut at the front vulnerable portion and both side vulnerable portions, and by applying a pressing force from the front to the upper part of the box body that can rotate, the portions of the additional vulnerable portions on both sides are easily bent and smoothly folded. Also, when opening the box, when the portion above the front vulnerable portion is pushed forward and broken along both side vulnerable portions, a situation where the additional vulnerable portions are bent also occurs, and the pushing operation during the box - closing operation also becomes smoother. Thereby, facilitation of folding when discarding the product storage box and facilitation of the operation when opening are achieved.

Embodiments for Carrying out the Invention

[0023] Hereinafter, embodiments of the product storage box of the present invention will be described in detail with reference to the drawings. In this embodiment, a paper box for a healthy beverage will be described as an example. The product storage box 10 shown in the developed view of FIG. 1 is for storing a bottle of a healthy beverage inside, and in the formed state, it is a box body having a cubic shape with an upper surface portion, a bottom surface portion, a front surface portion, a back surface portion, and side surface portions on both sides.

[0024] FIG. 2 shows the upper part of the product storage box 10 according to the embodiment before opening. As shown in the figure, the upper surface portion 10a, the front surface portion 10b, and the side surface portion 10c are shown. A characteristic configuration in the present invention is the additional weakened portion 12 linearly provided at the upper part of the side surface portion 10c. This additional weakened portion 12 is also formed at a position facing the side surface portion on the side not shown (please refer to the developed view of FIG. 1).

[0025] This additional weakened portion 12 is a portion where the shape retention force is weaker than that of the other side surface portions 10c, and is intended to facilitate bending. In this embodiment, thick cut lines are formed in a perforated shape.

[0026] For this additional weakened portion 12, it is sufficient that this portion is easily bendable. Therefore, not only a cut line but also a portion having a thickness thinner than that of other portions is sufficient. Also, the formation angle of the additional weakened portion 12 is at a position of 45 degrees with respect to the upper surface portion 10a and the front surface portion 10b, and extends to approximately the central position of the side perforation line 16 described later.

[0027] In addition, on the upper parts of the front portion 10a and the side portion 10c of the product storage box 10, a perforated cutting line is formed as a linear weak portion for facilitating cutting, similar to the storage box of a conventional health drink. A front perforated line 14 is formed on the front portion, and a side perforated line 16 is formed on the side portion 10c. A side perforated line 16 is also formed at a position facing the side portion on the side not shown (please refer to Fig. 1).

[0028] The side perforated line 16 in the present embodiment is characterized in that, compared with the conventional line being a straight line, it has a curved shape with a downward convex extended shape.

[0029] Fig. 6 is an enlarged explanatory view of the weak portion formed on the upper part of the box body. In the present embodiment, the additional weak portion 12 has a perforated cutting line of the same length formed thereon. Also, the side perforated line 16 is a zipper-type perforated cutting line 16a (at three positions) in the substantially central region, and the line at a position closer to the front portion 10b is a normal cutting line 16b (at one position), and this cutting line 16b is continuous with the front perforated line 14.

[0030] Furthermore, the line at a position closer to the back portion 10d is also a normal cutting line 16c (at one position). In the present embodiment, this cutting line 16c closer to the back portion 10d extends in the direction of the uppermost position of the side portion 10c and stops in front of the corner portion 10e at the upper end, but a cutting line 16c may also be provided up to the corner portion 10e at the upper end.

[0031] As described above, 16a in the central region of the side perforated line 16 is a zipper-type perforated cutting line in which a short cutting line is inserted obliquely at one end of a normal substantially straight cutting line, making it slightly more difficult to cut than the normal substantially straight cutting line and enhancing the shape retention force of that portion.

[0032] Figure 3 shows the state where the opening of the upper part of the product storage box 10 has started. As shown in the figure, both the front stitch line 14 and the side stitch line 16 are cut and separated, and the upper part 18 of the box body is rotated and opened with the upper position of the back part 10d as the hinge part.

[0033] This opening operation of the upper part 18 of the box body usually first involves the user pressing near the front stitch line 14 with a finger to make a cut, and then pushing up the upper part 18 of the box body to separate it from the lower part 20 of the box body and rotate it. Note that the operation of pushing up the upper part 18 of the box body to cut the side stitch line 16 is smoother because the side stitch line 16 is provided with a curve.

[0034] Also, when the upper part 18 of the box body is pushed up and rotated to separate the side stitch line 16, the part of the additional weak part 12 is easily bent. So when the front part 10b is strongly pushed in, that part bends outward, making the pushing-up operation of the upper part 18 of the box body easier.

[0035] As described above, the additional weak part 12 extends at the intermediate position (45-degree inclination) between the upper surface part 10a and the front part 10b, so it is easily bent by the pressing force and bends in a well-balanced shape.

[0036] Note that the opening operation of the upper part 18 of the box body is not limited to this operation. After separating the front stitch line 14 by pressing, it is also possible to easily open it by grasping both sides of the upper part 18 of the box body from both sides and rotating it upward. In that case, the part of the additional weak part 12 does not bend as in the case of a conventional box without the additional weak part 12 provided, but there is no problem at all.

[0037] Figure 4 shows a situation where the separated and rotated upper part of the box body 18 is further pressed, causing the part of the additional weakening part 12 to bend outward. The important function of the additional weakening part 12 is that when the upper part of the front part 10b is further pressed in this way and bends outward, the rotating upper part 18 of the box body becomes flat. That is, after taking out the stored goods, when discarding, it is desirable to crush the box as flat as possible to reduce the volume of garbage. By bending the part of the additional weakening part 12 outward, it can be easily crushed flat.

[0038] Figure 5 shows a state where the upper part 18 of the box body is completely crushed flat by bending the additional weakening part 12. As shown in the figure, the lower part of the box is also crushed and the whole becomes flat. In the case of a conventional box, the upper part 18 of the box body maintains a firm three-dimensional shape even after separation, so it is usually discarded as it is into the trash can when discarded. However, in the case of this embodiment, it can be made flat as shown in the figure with a simple crushing operation.

[0039] It should be noted that the present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the gist of the present invention. For example, in this embodiment, the side perforation line 16 is shown as being curved convex downward, but by making it curved convex upward, the upper part can be broken more easily. Also, various weakening parts in this embodiment can be formed by cutting lines on various types of perforations. In particular, the additional weakening part 12 does not need to be cut, and it is sufficient if it is easily bendable. Therefore, it is sufficient if a weaker part is formed on the line than other parts.
