  The present invention relates to a cardboard box provided with an article takeout assisting part so that an article can be easily taken out from a cardboard box containing a plurality of articles having a prismatic outer shape without gaps. Two cut lines are provided between the side plate and the top plate connected to the side plate, and it is possible to form an opening for exposing at least a part of the upper edge portion of the stored article and at least a part of the side surface subsequent thereto. The present invention relates to a corrugated cardboard box provided with an article takeout assisting part. The cardboard box of the present invention is characterized in that an opening is provided so that an article filled without a gap can be easily grasped by hand from the beginning, and easy to handle after the article is transported. It is also efficient.

  In general, a corrugated cardboard box is a box made of corrugated cardboard material, and it is light and strong, shock-absorbing due to its structure, convenience that can be used after being folded many times, etc. Widely used in fields such as storage, transportation of fruits, etc., transportation of bottles filled with liquids such as sake and soy sauce. Normally when folded, it becomes a flat plate and can be reassembled using only cardboard boxes by folding the lids together. However, when reusing, use adhesive tape such as gum tape, craft tape, OPP tape, etc. There are many. When a heavy object such as a machine is put in, it can be used by using an adhesive and further reinforcing it by fixing with a metal fitting or a band. Cardboard boxes have shapes such as A type (A type), B type (B type), and C type (C type), but the most popular is the shape called A type (A type). This type is often used for transporting fruits and vegetables with lids that can be opened and closed at the top and bottom of the box.

  In order to store an article in a cardboard box, an automated apparatus is usually used in a factory or the like, and mass-produced articles are loaded in a short time. However, as people get closer to the consumer, taking out the articles stored in the cardboard boxes has more opportunities for human intervention, which is often troublesome. Therefore, how to efficiently and safely take out the articles stored in the cardboard box without requiring troublesome work is one of the issues to be solved for cardboard transportation, and technology development is underway. I have been. In order to make it easy to take out articles from the cardboard box, many techniques have been proposed in which the structure of the cardboard box is improved. An example of such cardboard box improvement technology will be described next.

  In order to take out the articles stored in the cardboard box, an opening is provided by cutting a part of the cardboard box or by removing a part of the cardboard box. For example, in order to enable easy removal without damaging plants or the like housed in a vertically long cardboard box, a handle hole is provided in one top surface portion of the cardboard box, and this top surface portion is continued. By providing intermittent cuts on both side edges of the side part, and pulling the top part to the outside by placing a hand in the handle hole, the side part can be greatly opened outward from the top part. When carrying out repair work in a cardboard box (Patent Document 1) from which goods can be taken out, or in a car repair shop / maintenance shop, etc., it is possible to prevent the worker's dirty work clothes from contaminating the customer's car seat. Folding simple disposable sheet covers one at a time, stacking and storing multiple sheets in a cardboard box, and individually taking the polyethylene film stored inside the cardboard box There is a storage box forming the outlet for exiting (Patent Document 2).

An opening is provided in a cardboard box by tearing a strip-shaped cut portion in the cardboard box. For example, in a corrugated cardboard box which is characterized by the shape of the band-shaped cut and is cut along the cut part to take out the contents, the band-shaped cut part is divided into two adjacent and parallel cut lines. In addition, the two cut lines are formed so that the interval between the two cut lines gradually decreases from the starting end of the strip-shaped cut portion toward the end. A cardboard box (Patent Document 3) that can be opened is proposed.
In addition, as an example of corrugated cardboard characterized by a cut at the tearing part, the side plate can be maintained with sufficient strength in the stacking direction, and by providing a cut line that can be easily opened, the side plate can be opened and the contents can be opened. The corrugated cardboard box that can be taken out is provided with, for example, a vertical cut line that bisects the side plate to the left and right, and the vertical cut line is defined as two discontinuous cuts that are discontinuous in the cutting direction, and Each of the discontinuous cuts extends in the cutting direction starting from the outer edge of the diagonal cut extending through the liner on the front and back outer sides of the cardboard and extending outward in the cutting direction. A cardboard box (Patent Document 4) formed by parallel cuts having a depth that does not reach the surface liner has been proposed.

  The product is packed and transported safely between the factory and the customer. After the product arrives, it can be stored temporarily, and the cardboard box for packing can be taken out easily. A corrugated cardboard box having a lid provided on one side in a knockout manner and packing an article, wherein the lid is provided at an upper side provided at an upper part of one side of the box and at both ends of the upper side. A series of fractured cuts forming a connecting side piece and a lower side are provided, and a tongue-like body is extended at a substantially central portion of the lower side, and the fractured cuts are After the separation, a packaging cardboard box (Patent Document 5) is proposed in which the lid body is freely opened and closed with the upper side as an axis.

  In addition, as another example of the removal method, it is not easy to take out a product alone from a cardboard box containing a large product such as home appliances or office equipment. There is an example in which a packaging box is provided that makes it easy to take out the contained items. For example, a corrugated cardboard box for storing office equipment, etc., which can be configured to have the above-mentioned leg holes by breaking the sewing machine wires formed on two or more side surfaces, and by breaking the sewing machine wires A side surface part surrounded by the sewing machine line is inclined outward, and a structure is provided in which a stepping tongue piece can be formed (Patent Documents 6 and 7).

  Cardboard boxes are generally widely used for transportation purposes. They are lightweight, but they have a shock-absorbing property that protects the inside from external shocks, are confidential, and have excellent durability. It is a container that can be safely protected and transported. In addition, cardboard boxes are light, strong, and can be easily made in a size suitable for the contents, so not only packaging costs are reduced, but recently, cosmetic printing technology has been promoted, so it can also be used as an over-the-counter display or promotional package. The range of use is widened. Today, logistics rationalization, labor saving, and speed-up are important strategies for companies to survive toward the next generation. Paper containers and cardboard boxes have become a major force in their own economic efficiency, efficiency, and recyclability. I play a part.

In order to store goods such as goods in a cardboard box, it is usually the case that an automatic device that grips the goods that are produced and flows through the line and packs them at once is often required manually. Absent. However, if the goods packed in cardboard boxes are transported to a store or the like, which is a demand destination required for each box, for example, when the goods are taken out and displayed at the shop front, the goods must be taken out one by one by the person. There are often. If the article is a bare bottle or a can, a space remains between the articles in the cardboard box, so it is easy to put the finger into the space and take out the article.
However, if the article has a shape such as a rectangular parallelepiped or a cube, for example, the article is stored in the cardboard box without any space, so that there is no space necessary for putting a finger on the article at the top. This is often experienced. Since a space is formed by taking out one article from the opening of the cardboard box, there is no difficulty in taking out from the second piece.

  In such a situation, the inventors have accumulated earnest research for the purpose of developing a cardboard box having a structure in which the first one of the articles stored in the cardboard box can be easily taken out. By forming two cut lines between the side plate and the top plate connected to the side plate, it is possible to form an opening for exposing at least a part of the upper edge of the stored article and at least a part of the side surface following it. Thus, the present invention has been completed. The present invention comprises a corrugated cardboard box provided with an article takeout assisting portion.

The present invention for solving the above problems is constituted by the following technical means.

A cardboard box for storing the article described in ( 1) above, in which the article takeout assisting part is formed by two cut lines parallel to the connecting line between the side plates extended so as to expose a part thereof .

  According to the present invention, a corrugated cardboard box is provided that is provided with an article take-out assisting portion that can form an opening for exposing at least a part of the upper edge of the stored article and at least a part of the side surface following the upper edge. Can be provided. The production of the cardboard box of the present invention requires only a simple process, so that the manufacturing cost of the cardboard box does not increase significantly. Moreover, the opening of the article take-out assisting portion can be accurately formed at a predetermined location without impairing characteristics such as the strength of the cardboard box due to the small partial processing. By forming the incision line with the perforation, it is possible to prevent the corrugated paper on the opening end face from being sharp like a razor, and thus it is possible to suppress the wound on the hand that comes in contact with the incision end face. Furthermore, since the articles stored in the cardboard box can be easily removed manually, the work efficiency is improved.

In contact with the inner wall of the cardboard box. Further, when the lid is opened, the upper end of the side plate of the cardboard box and the upper edge of the article are coincident with each other, so that even a space where the article can be lifted with a finger cannot be found. In this case, it is necessary to form a space where fingers can enter by pushing the side plate of the cardboard box or bringing the items together, but this is not only a powerful work that applies force to the fingertips, but also damage or deformation of the items. Unexpected accidents may occur. In the present invention, an article takeout assisting part for easily taking out an article is formed.

[Cardboard box]
A corrugated cardboard box is a corrugated cardboard sheet that is processed into a box shape. Corrugated sheet is usually a plate-like paper product that is made of base paper that is tough with a multilayer structure and processed so that it can be used for packaging materials. The corrugated sheet is sandwiched between front and back paper and bonded to give strength. Corrugated cardboard has a structure in which corrugated wrinkled paper (core) is bonded to strong paperboard (liner). Although many cardboard boxes having different shapes and structures are commercially available, the cardboard box used in the present invention is not particularly limited. However, the upper lid, the lower lid, and the storage portion are integrally formed to form a rectangular parallelepiped or a cube. It is preferable to use a prismatic shape such as a mandarin orange box shape (FIG. 1).

[Storage goods]
The articles stored in the cardboard box of the present invention are, for example, rectangular parallelepiped shaped articles such as a rectangular prism shape or cubes. Usually, however, an article similar to the inner shape of the cardboard box or a plurality of them is combined. An article that forms a similar shape to the inner shape of the cardboard is a typical example. Specifically, cosmetics and liquors in a cosmetic box are typical examples, and furthermore, confectionery in a box and the like are exemplified, but it is not limited to these specific articles.
In particular, when alcoholic beverages packed in large-capacity bottles are put in a decorative box and densely stored in a cardboard box, the outer shape is large and it has a considerable weight, so you find a small space between the cardboard boxes. However, it takes a relatively large force to take out this first, and it is not easy. If the first article cannot be taken out from the cardboard, the only way is to destroy the cardboard box or turn it over and take out the article, and such rough means have problems such as destruction of stored items.
In addition, the external shape of the stored item is not a rectangular column shape, but it is packed to form a square column shape when stored in a cardboard box, that is, for an item that becomes a square column shape by combining a plurality of stored items at the time of storage. Even the present invention is applied. For example, two triangular prism-shaped articles are combined into a quadrangular prism, and a large number is stored in a cardboard box with this as a unit. In this way, the article is stored in the cardboard box of the present invention according to the shape of the article.

[Article Extraction Assistance Section]
The present invention forms an article take-out assisting portion useful when an article is first taken out from a cardboard box, and exposes at least a part of the upper edge of the stored article and at least a part of the side surface subsequent thereto. Are formed. When the upper lid of the cardboard box in which the article is stored is opened and the cut line of the article takeout assisting part is cut to provide an opening, the upper surface and part of the side surface of the article are exposed. Therefore, if the top and side surfaces of the article are used as a clue, the first article can be easily taken out from the cardboard box.

The article takeout assisting portion is provided with two cut lines extending between the side plate and the top plate connected to the side plate to expose at least a part of the upper edge portion of the stored article and at least a part of the side surface subsequent thereto. Can be formed by cutting cut lines, and these cut lines are usually processed in the manufacturing process of the cardboard box.
FIG. 1 shows an example in which four prismatic articles are stored in a cardboard box without gaps, and an opening is formed by the article take-out assisting unit. The side and upper edge of the article are exposed from the opening. Yes. FIG. 2 shows a three-dimensional view of a corrugated cardboard box having an opening as seen from the side. FIG. 3 shows a state in which a corrugated cardboard box having an opening is viewed from the side. When the top plate is opened outward in the range where the angle θ formed by the top plate and the side plate is less than 180 degrees, the article takeout assisting portion is separated from the top plate and the side plate to form an opening. In FIG. 3, the article take-out assisting section cut along the cut line remains attached to the box, but there is no problem in taking out the article. Further, the article takeout assisting part may be cut off (FIG. 4), and when the article takeout assisting part is completely removed from the cardboard box, the article can be more easily contacted from the opening.

  The shape of the opening of the article takeout assisting portion may be a rectangle shown in FIG. 2 or the like, a trapezoidal shape as shown in FIG. 7 or FIG. 8, or a shape having a line segment with a wavy curved portion. The openings are formed by cutting the cardboard material into these shapes or by cutting only the left and right cut lines. When only the left and right cut lines are cut and the opening is not cut, a fold line orthogonal to the cut line can be formed in advance in the article take-out assisting portion to help form and hold the opening.

[Installation position of the article removal assistance section]
The opening, that is, the article takeout assisting portion, is provided with two cut lines between the side plate and the top plate connected to the side plate to expose at least a part of the upper edge portion of the stored article and at least a part of the side surface subsequent thereto. Is not particularly limited, for example, the end of the opening is installed at the boundary between the article and the article stored in the cardboard box (FIG. 1), and the opening is installed across the boundary between the articles. (FIG. 4), the opening is installed in the same length as the width of the article and corresponding to the width. However, the opening is selected according to the property of the article to be stored. There are cases where articles are stacked in two or more stages in a cardboard box. When all the uppermost articles are taken out, the same problem as the uppermost stage occurs again in order to take out the articles first in the next stage. In order to solve this problem, it is preferable that the uppermost article and the next article can be taken out using the opening provided by the article take-out assisting unit. This can be solved by extending the opening so as to expose the upper edge and the side surface of the next article. FIG. 4 shows an external appearance when the stored article is stacked in two stages and the opening of the article take-out assisting portion is extended.

  The cut line is formed for the purpose of facilitating the formation of an opening in the article take-out assisting part to suppress wounds on the hand, and providing an opening accurately at a predetermined location, but the conventional technique is applied. For example, a perforation is formed by pressing a mold in which a large number of convex portions are continuously arranged in a comb shape. Further, a cut line is formed by making a cut to such an extent that it is not completely separated from the front surface and / or back surface of the corrugated board material by a cutting blade.

  EXAMPLES Next, although this invention is demonstrated concretely based on an Example, this invention is not limited at all by the following Examples.

In the corrugated cardboard box of the present invention, a specific example in which two parallel score lines 61 and 61 are provided between the side plate 1 and the top plate 2 with the article takeout auxiliary portion 6 will be described below.
In the cardboard box of the present invention, first, a portion indicated by a thick solid line in FIG. 5 is cut from a corrugated board material (plate), and the portion indicated by a thin solid line is pressed with a squeezing stick or the like to provide a groove to form a crease. The article takeout assisting unit 6 is provided in the process of cutting the cardboard material. The thin solid line portion of the article takeout assisting portion 6 in FIG. 5 is a cut line 61, and a series of perforation forming tools continuously having a number of sharp teeth on the comb teeth are pressed against the cardboard material and penetrated through the cardboard material. It is formed by providing a through hole. A cut line 61 of the article takeout assisting portion 6 is formed across the connecting portion (fold) between the top plate 2 and the side plate 1. The cut line 61 is provided in parallel to the side plate 1 and the fold of the side plate 1.

In FIG. 4, the inside of the cardboard box of 244 × 318 × 211 mm is designed so that a cosmetic box made of a rectangular parallelepiped having a size of 244 × 107 × 107 mm is stored, and 720 mL of sake bottles are packed in the cosmetic box. Yes. The article takeout assisting unit 6 is provided with two cut lines 61 and 61 having a length of 110 mm at intervals of 45 mm, and a folding line 62 is provided orthogonal to the cut line 61. The opening was provided at about 40% of the width of the stored article. In addition, a fold line is provided on each of the line 63 connecting the upper ends of both the cut lines and the line 63 connecting the lower ends, so that the opening 5 after cutting the cut lines 61 can be stably maintained. In FIG. 2, the external appearance of the cardboard box after forming the opening 5 is shown. From the opening 5, the side surface 7 and the upper edge portion 4 of the stored article are exposed. FIG. 3 is a side view of the cardboard box in FIG. It becomes easy to maintain the bent shape by the fold 63 provided in the article take-out assisting portion 6.
FIG. 1 shows the appearance of a cardboard box that stores articles, but here, it is illustrated as four articles. When the first cosmetic box 3 was taken out from the corrugated cardboard box of this embodiment, it could be easily grasped and lifted from the opening 5 using the cosmetic box 3.

In this example, a cardboard box in which the shape of the article take-out assisting portion 6 was changed was manufactured. The cardboard box was manufactured in the same manner as in Example 1. An example in which the shape of the article take-out auxiliary unit 6 is a trapezoid is shown in FIGS. The cut line 61 of the article takeout assisting portion 6 was formed by cutting in a straight line so as to leave a part of the cross section of the cardboard material so that it can be easily cut. In the line 63 connecting both ends of the cut line 61, the opening 5 is formed by removing the article take-out auxiliary portion 6 by making it easy to cut similarly to the cut line 61. At this time, the opening 5 can be easily removed without being prevented from contacting the article with a finger or the like.
Further, even when the both ends 63 were not separated as in the case of Example 1, there was no difficulty in taking out the article.
