Description

  The present invention relates to a bag-in-box in which a bag containing mainly liquid contents is stored in an outer box made of cardboard or the like.

  Conventionally, a bag-in-box in which liquid contents such as drinking water, alcoholic beverages, seasonings and the like are accommodated in a resin film bag and the bag is accommodated in a cardboard outer box has been used. This bag-in-box can be stored in a space-saving state in a folded state because the bag and the outer box can be separated when not in use. Furthermore, after use, the inner bag and the outer box can be separated, and since both can be reduced in volume by folding, it has the advantage of high convenience in disposal. .

  On the other hand, the above-mentioned bag-in-box increases the overall weight when the contents in the bag inside the outer box are filled, so it is necessary to carry the outer box by pressing it with both hands. It was heavy and difficult to handle easily.

  Therefore, in order to make handling of such a bag-in-box convenient, a “packaging box for packed beverages” described in Patent Document 1 has been developed. This packaging box is formed with a vertically oblong hole for inserting a finger of a hand along the approximate center in the vertical direction near the corners of the two wall surfaces provided next to the vertical box. It is possible to lift the packaging box with one hand by inserting a finger of one hand into the hand and holding it.

  In addition, a cut line for forming the above-mentioned hole in the packaging box is provided leaving a crease line at the hole edge, and the vertical fold applied to the center of this crease line and the one part in the hole A structure is formed in which a reinforcing member is formed when the hole is grasped by hand by folding one part inward along the eye line.

  However, in the above configuration, the reinforcing body formed by folding back the one part in the hole is formed only in the vertical width of the hole, so that the package can be reinforced even if the hole can be reinforced. It is impossible to reinforce the entire top and bottom corners of the box.

  Therefore, when the contents for packed drinks stored in the packaging box are heavy, if the finger of one hand is inserted into the opening of the packaging box and is gripped, the vicinity of the upper or lower end of the opening There was a risk of bending, deformation, or damage.

  The present invention is a reinforcement which can be easily held with one hand even if it is an outer box containing heavy contents, and the outer box is not bent, deformed or damaged. An object of the present invention is to provide a bag-in-box that has a simple structure.

  In order to solve the above problems, the bag-in-box according to claim 1 of the present invention has a shape formed by developing an exterior box for storing contents, and a continuous side body that forms a body part of the exterior box. In a bag-in-box comprising an upper lid and a bottom lid, an adhesive strip formed along one end side of the continuous side body and a reinforcing piece formed along the other end side of the continuous side body are packaged. It is formed to have a length similar to the height of the top and bottom of the box, and the glue margin piece adheres to the outer surface of the end of the continuous side body that contacts when the outer box is assembled. The pair of elongated holes formed in the vicinity is cut and formed with the fold line left on the long side close to each end side so that it can be bent inside the outer box.

  The bag-in-box according to claim 2 of the present invention is characterized in that, in claim 1, the reinforcing piece is made free inside the outer box without bonding.

  Furthermore, the bag-in-box according to claim 3 of the present invention is the bag-in-box according to claim 1, wherein when the reinforcing piece is bonded to the inner side surface of the end portion of the continuous side surface that contacts the reinforcing piece, the length of the reinforcing piece is the length of the adhesive margin piece. It is the same as that.

  According to the bag-in-box of the present invention, in the structure after assembling the exterior box, the paste margin piece and the reinforcing piece are provided along the corners where the elongated holes on both sides for inserting the fingers of one hand are formed. The glue margin piece forms a reinforcing structure bonded to the outer side surface of the end portion of the side body that contacts the glue margin piece. In addition, the reinforcing piece may be bonded to the side surface of the end portion that contacts the same as the adhesive piece, but as a configuration in which the reinforcing piece is in a free state at the inner corner of the outer box without being bonded, The bonding process may be omitted.

When the reinforcing piece is bonded to the side surface of the end portion that contacts the reinforcing piece, the reinforcing piece and the glue margin piece form a reinforcing structure having an L-shaped cross section at the corner portion after the outer box is assembled. In addition, if the bag that contains the contents is stored inside the outer box when the reinforcing piece is left in a free state at the inner corner of the outer box without adhering the reinforcing piece, the reinforcing piece is pressed against the bag. Is pressed against the inner wall of the side body, and forms a reinforcing structure at the corners of the outer packaging box in an L-shaped cross-section with the adhesive margin piece.

  For this reason, when lifting the exterior box with the fingers of one hand inserted into the long holes on both sides, even if the contents of the bag stored in the exterior box are heavy, the exterior box is long. It is possible to realize an outer box structure that is not bent, deformed, or damaged in the vicinity of the shape hole.

  Moreover, in the present invention, the pair of elongated holes formed in the vicinity of each end of the continuous side body is cut and formed while leaving a fold line on the long side close to each end, It has a structure that can be folded inside the outer box. Therefore, if you insert your fingers into the long holes on both sides and hold them, each finger will grip the folded piece inside the outer box, so it will hurt your fingers. Therefore, it is easy for women and girls to grip and hold with one hand.
