Description

[Technical field]

[0001] The present invention relates to a cardboard box manufactured by processing a cardboard sheet in which flat paper (liner) and corrugated paper (core) are bonded together with adhesive to form a single structure, and which has handle holes opened at the top on both width sides of the box. [Background technology]

[0002] Corrugated boxes are manufactured by processing cardboard sheets which are made up of three sheets of paper - flat paper on the top and bottom (liners) and one wavy sheet of paper (core) - and can be designed to the optimum dimensions to suit the contents of the product. This means that there is a low possibility of pinholes (small holes) being formed when products rub against each other due to vibrations during transport, such as in retort-packaged or vacuum-packed foods, and this ensures a high level of product safety. Corrugated boxes are also used as the main transport packaging by food manufacturers and a variety of other fields. Furthermore, cardboard boxes which are designed to the optimum dimensions to suit the contents of the product are lightweight and do not leave any wasted space, which increases the loading efficiency and transport efficiency of trucks. Furthermore, cardboard, which is made from paper, is a natural material which is 100% renewable, and in the unlikely event that it is left unrecycled, it will eventually return to the soil, making it a highly durable product.

[0003] Incidentally, when a cardboard box as described above is loaded with relatively heavy products during transportation, the box is carried by hanging the index finger, middle finger, ring finger, and little finger from the handle holes provided at the top of both sides, but when lifted by only one arm, the box may tear from the handle holes above the outer side of the index finger and the handle holes above the outer side of the little finger. In the event of tearing, the box is difficult to carry and cannot be sold in bulk. In order to solve the above problem, the applicant has filed an application for a cardboard box that has finger holes for the index finger, middle finger, ring finger, and little finger instead of the handle holes, dispersing the load from the cardboard box, making the finger holes less likely to tear, and making the box easy to carry (submission date: September 11, 2023, application number notification postcard not yet received on the submission date of this application: September 21, 2023). Summary of the Invention [Problem to be solved by the invention]

[0005] The cardboard box applied for by the applicant has a human-made product attached to the upper part of both sides of the cardboard box. TIFF2025048678000002.tif6170The opening is centered on or near the curved line, but the finger holes are opened in the upper parts of both width sides. Therefore, when a carrier puts their fingers in the finger holes and moves with their arms outstretched, the carrier's thighs hit the cardboard box, making it difficult to carry.

[0006] The present invention has been made to solve the above-mentioned problems, and aims to provide a cardboard box that has finger holes in the lower part of both width sides of the box for hanging the index finger, middle finger, ring finger, and little finger, and by supporting the cardboard box with the index finger, middle finger, ring finger, and little finger and the belly part, the cardboard parts above each finger hole are less likely to tear and the box is easy to carry. [Means for solving the problem]

[0007] In order to solve the above problem, the invention of claim 1 provides a cardboard box having a lower portion on both sides of the box. TIFF2025048678000003.tif7170A cardboard box characterized by having an opening with its center on a curved curve line or near a curved line.

[0008] The invention of claim 2 is a cardboard box with ... TIFF2025048678000004.tif7170It is a cardboard box with an opening near the center.

[0009] The invention of claim 3 is a cardboard box having, at the lower part of both width sides, a finger hole for the index finger, a common finger hole for both the middle finger and ring finger, and a finger hole for the little finger.

[0010] The invention of claim 4 is a cardboard box having a common finger hole for both index finger and middle finger, and a common finger hole for both ring finger and little finger, both opened at the lower part of both width sides of the cardboard box.

[0011] The invention of claim 5 relates to the cardboard boxes of claims 1 and 2, in which each circular finger hole is opened in a multi-purpose shape so that the index finger, middle finger, ring finger, and little finger can be hung from both one long face side of the cardboard box and the other long face side on the opposite side of the cardboard box, and to claim 3, in which each circular finger hole is opened in a multi-purpose shape so that the index finger, middle finger, ring finger, and little finger can be hung from both one long face side of the cardboard box and the other long face side on the opposite side of the cardboard box. Effect of the Invention

[0012] This cardboard box has finger holes for the index finger, middle finger, ring finger, and little finger opened at the bottom on both width sides of the box. Therefore, even when the box is packed with relatively heavy products, the weight of the cardboard box is distributed among the finger holes for the index finger, middle finger, ring finger, and little finger, making the finger holes less likely to tear. Furthermore, when the box is carried with the carrier's arms outstretched and the fingers hooked in each finger hole, the holes do not come into contact with the carrier's thighs, making it easy to carry.

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of a cardboard box according to an embodiment of the present invention, showing the finger holes opened on the lower side of one of the width faces, while the finger holes opened on the lower side of the other width face are omitted. Fig. 2 is a schematic side view showing the circular finger holes opened on the lower side of both width faces of the cardboard box, and the finger holes opened on the lower side of one of the width faces.

[0015] As shown in Figs. 1 and 2, the cardboard box of the present invention has circular finger holes 3, 4, 5, and 6 (not shown on the 2a side) for holding the index finger, middle finger, ring finger, and little finger at the lower part of both width sides 2 and 2a of the cardboard box 1. It has TIFF2025048678000005.tif7170.

[0016] In addition, the cardboard box shown in Figures 1 and 2 has circular finger holes 3, 4, 5, 6 that are opened in the lower part of both width sides 2, 2a for hanging the index finger, middle finger, ring finger, and little finger, respectively, but as shown in Figure 3, cardboard box 1a may also be provided with three circular finger holes 9, 10, 11 for hanging the index finger, middle finger, and ring finger, excluding the little finger, and further, in the case of a cardboard box packed with relatively light contents, cardboard box 1b may also be provided with two circular finger holes 12, 13 that are opened in two places for hanging any two of the index finger, middle finger, ring finger, and little finger, respectively, as shown in Figure 4.

[0017] The cardboard boxes 1, 1a, 1b of the present invention and 1c and 1d described below are suitable for packing contents such as spherical bottles or plastic PET bottles that taper downwards, like a bowling pin, so that after the contents have been packed into the cardboard boxes, there are spaces on the lower inside of both width sides 2, 2a where people can hook their fingers.Furthermore, in the case of flexible refill pouches filled with hair care products such as shampoo, conditioner, treatment, body soap, etc., the cardboard boxes can be used to pack flexible contents so that, after the cardboard boxes are packed and sealed, when a finger is inserted into each finger hole, the refill pouch will deform and the finger will hit the hole, causing the pouch to deform.

[0018] Therefore, if each finger hole is circular or elliptical, or an upper semi-elliptical shape obtained by dividing an ellipse in the long axis direction, and if a part of the finger hole is a half-open finger hole connected to the cardboard forming both width sides 2, 2a, the cardboard folded inward of the cardboard box can prevent the fingertips from directly contacting the surface of the flexible refill pouch filled with shampoo, conditioner, treatment, body soap, etc. Also, in order to prevent the fingertips from directly contacting the surface of the flexible refill pouch, each finger hole may be shaped as a vertically long oval hole (the folding direction of the corrugated paper that forms the core) or a vertically elliptical half-open finger hole as shown in Figure 5, and the cardboard folded inward will be further bent in a valley shape when it comes into contact with the contents, preventing direct contact of the fingertips. Therefore, it is advisable to provide one or more fold lines by pressing so that the oblong hole shown in Fig. 5 can be easily folded in the horizontal direction. The finger holes in the cardboard boxes described below should also be of a similar shape, with a part of the finger hole being a half-open hole connected to the cardboard that forms both width sides 2, 2a.

[0019] As shown in Figures 1 and 2, the circular finger holes 3, 4, 5, and 6 for hanging the index finger, middle finger, ring finger, and little finger at the lower part of both width sides 2, 2a of the cardboard box are opened in a universal shape (diameter) that allows the index finger, middle finger, ring finger, and little finger to be hung from both sides of one length side 14 of the cardboard box and the other length side 14a on the opposite side of the cardboard box (the same applies to the circular finger holes at the lower parts of both width sides 2, 2a of the cardboard box described below). Therefore, finger holes 3, 4, 5, and 6 for the index finger, middle finger, ring finger, and little finger shown in Figures 1 and 2 are for when a person is positioned on one long surface 14 of cardboard box 1. When a person is positioned on the other long surface 14a on the opposite side of cardboard box 1, the little finger will be placed in finger hole 3, the ring finger in finger hole 4, the middle finger in finger hole 5, and the index finger in finger hole 6.

[0020] Furthermore, as in the cardboard box shown in Fig. 3, the finger holes 9, 10, 11, which are opened in a circular shape in the lower part of both width faces 2, 2a of the cardboard box for hanging the index finger, middle finger, and ring finger, are opened in a versatile shape (diameter) so that the index finger, middle finger, and ring finger can be hung from both sides of one length face 14 of the cardboard box and the other length face 14a on the opposite side of the cardboard box. Therefore, the finger holes 9, 10, 11 for hanging the index finger, middle finger, and ring finger shown in Fig. 3 are for the case where a person is positioned on one length face 14 side of the cardboard box 1, and when the person is positioned on the other length face 14a on the opposite side of the cardboard box 1, the ring finger is hung in the finger hole 9, the middle finger is hung in the finger hole 10, and the index finger is hung in the finger hole 11.

[0021] Furthermore, as shown in FIG. 4, in the case of cardboard box 1b having two circular finger holes 12, 13 for receiving any two fingers from among the index finger, middle finger, ring finger, and little finger, these may be selected appropriately depending on the person carrying the cardboard box.

[0022] As shown in FIG. 6, finger holes 3, 4, 5, and 6 for inserting the index finger, middle finger, ring finger, and little finger are provided on the lower part of both width sides 2 and 2a of the cardboard box 1c, and finger holes 6 for inserting the index finger, middle finger, ring finger, and little finger are provided on the bottom surface of the cardboard box 1c. TIFF2025048678000006.tif7170 box 1c may also be used. Also, in the case of this cardboard box 1c, the opening is made in a versatile shape (diameter) that allows a person to hang the index finger, middle finger, ring finger, and little finger from both sides of one long surface 14 of cardboard box 1c and the other long surface 14a of the opposite side of cardboard box 1c, so that when a person is positioned on the other long surface 14a of the opposite side of cardboard box 1c, the little finger will be hung in finger hole 3, the ring finger in finger hole 4, the middle finger in finger hole 5, and the index finger in finger hole 6.

[0023] Furthermore, as shown in Fig. 7, when the cardboard box 1d filled with the contents is relatively light, the cardboard box 1d may have a finger hole 15 for the index finger, a common finger hole 16 for both the middle finger and the ring finger, and a finger hole 17 for the little finger, which are opened at the lower part of both width sides 2, 2a of the cardboard box 1d. As shown in TIFF2025048678000007.tif12170, the opening may be on or near a curved line that curves toward the top surface (the top surface when the outer flaps are closed as shown in FIG. 7). Also, in the case of cardboard box 1d, when a person is positioned on one of the long faces 14a on the opposite side of cardboard box 1, the index finger will be placed in finger hole 17, the middle finger and ring finger will be placed in finger hole 16, and the little finger will be placed in finger hole 15.

[0024] Furthermore, as shown in Fig. 8, when the cardboard box 1e filled with contents is relatively light, the cardboard box 1e may have a common finger hole 18 for hanging both the index finger and the middle finger, and a common finger hole 19 for hanging both the ring finger and the little finger, which are opened in the lower part of both the width faces 2, 2a of the cardboard box 1e. The common finger hole may be a round hole elongated in the left-right direction, or may be opened in a circular shape that allows both fingers to be hung. Also, in the case of the wooden cardboard box 1e, when a person is positioned on one of the length faces 14a on the opposite side of the cardboard box 1, the index finger and the middle finger are hung in the common finger hole 19, and the ring finger and the little finger are hung in the common finger hole 17.

[0025] In each of the cardboard boxes described above, the finger holes are opened in the lower part of both width faces 2, 2a of the cardboard box, but the finger holes may be opened in the lower part of both length faces 14, 14a of the cardboard box, and further, the finger holes may be opened in the lower part of both width faces 2, 2a and in the lower part of both length faces 14, 14a of the cardboard box. The opening positions of the finger holes should be indicated by printing or the like.

[0026] In addition to cardboard boxes made from a cardboard sheet consisting of three sheets of paper: flat top and bottom papers (liners) and one corrugated sheet of paper (core), the present invention may also be applied to other boxes, such as cardboard boxes made from other types of cardboard sheets, such as single-sided cardboard or double-sided cardboard, and even cardboard boxes made from cardboard.

[0027] The above description is of the embodiment of the present invention, but is not intended to limit the present invention. Various modified examples can be easily implemented. For example, in the cardboard box of the present invention, finger holes are opened in the lower part of both sides of each cardboard box, but in the cardboard box of the applicant's application (submitted on September 11, 2023), finger holes are opened in the upper part of both sides of each cardboard box. Furthermore, finger holes may be opened between the lower part of both sides of the cardboard box and the upper part of both sides, which is suitable for cardboard boxes in which general-purpose PET bottles are stored in two levels, and also includes embodiments that are configured by appropriately combining the components, functions, features, or method steps in each embodiment. [Industrial Applicability]

[0028] This invention provides finger holes for the index finger, middle finger, ring finger, and little finger on the lower side of both width sides of the cardboard box, so that the weight of the cardboard box is distributed to each of the finger holes.As a result, the cardboard above each finger hole is less likely to tear, and because the finger holes are less likely to tear, a cardboard box that is easy to carry is obtained and can be used in the field of cardboard boxes.
