Description

  The present invention relates to a packaging box for confectionery, ice confectionery, etc., and relates to an improvement in the lid structure of the packaging box that does not cause section waste when opened.

  Conventionally, as disclosed in, for example, Patent Document 1 (Japanese Patent Application Laid-Open No. 05-124638), a hexahedron having an accommodation space is formed of cardboard or the like as a packaging box for food or the like, and a folded flap portion is formed. Sealed with an adhesive, and strip-shaped separation pieces are formed on the flap portion such as perforations. And the user peels off this strip-shaped piece and opens it. Such a packaging form is widely used as a packaging form for foods and the like because it can be seen at a glance whether or not it has been opened.

  In such a strip-like piece, there is a problem that the strip-like piece after separation is left as paper piece dust when opened, and as an improvement, for example, as disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 2006-137464), the box body Folding the inner and outer folding flaps from the opposite sides of each other and binding them together with an adhesive to form an opening lid, and providing a tear-off line on the outer folding flap on this opening lid, the user cuts off the separation line Opening structures have been proposed.

  In this document, a protrusion-shaped pressing piece is provided on the outer folding flap, a notch groove for inserting the pressing piece is provided on the inner flap, and the closing piece can be closed by inserting the pressing piece into the notch groove after opening. ing.

Japanese Patent Laid-Open No. 05-124638 JP 2006-137464 A

  As described above, in the lid structure in which the strip-shaped cut piece is provided on the opening lid, a piece of paper is generated at the time of opening, and the processing is troublesome. In view of this, a lid structure has been proposed in which a separation piece such as a perforation is provided on the outer folding flap. In the case of this structure, a part of the outer folding flap is attached to the inner flap with an adhesive after being cut off, so that unnecessary paper scraps do not remain at the time of opening.

  Conventionally, as disclosed in Patent Document 2, the outer folding flap is provided with a perforation, and the separation portion is separated by pressing toward the inside of the box. Thus, in the opening structure which pushes a flap into a box inside, the problem which cannot be separated easily arises with the accommodation state of the contents.

  At the same time, an insertion convex piece is formed by a separating line in the opening lid to reclose after opening, and the convex piece is inserted into the insertion groove formed in the inner folding flap.

  The present inventor has provided an opening for inserting the user's fingertip between the inner folding flap and the outer folding flap based on the idea of separating the separation line formed on the outer folding flap by pulling it outward. I came up with the idea of forming a separation line.

  An object of the present invention is to provide a packaging box that can be easily opened regardless of the contents stored state without generating paper scraps at the time of opening, and can be closed again after opening. Furthermore, this invention makes the subject the provision of the packaging box which can be processed in the folded state, without being bulky after use.

  In order to achieve the above object, the present invention comprises a box main body in which an opening lid is overlapped and bonded with an inner flap and an outer flap, and the outer flap is divided into an adhesive portion and a non-adhesive portion. A separation line, a pair of insertion pieces that are continuous with the separation line and have a pushing opening in the center, and a margin part are formed. On the other hand, the inner flap is provided with an insertion groove for inserting the insertion piece. Then, the inner flap is pushed into the accommodation space from the pushing opening, the fingertip is inserted, and the outer flap is pulled up to be separated into two.

  A packaging box (A) having a storage space, comprising a box body (10) having an appropriate shape such as a rectangular parallelepiped, a rectangular parallelepiped, and a cylinder, and an opening lid (12) formed on the box body, The inner flap (16) formed on one of the opposing side plates (15) of the box body and the outer flap (17) formed on the other are overlapped and adhered. The outer flap is pushed into the center of the separation line (29) divided into two parts, the adhesive part (17a) and the non-adhesive part (17b), the glue part formed on the adhesive part, and the separation line. A pair of insertion pieces (27a, 27b) having openings are provided, and an insertion groove (26) for inserting the pair of insertion pieces is provided on the inner flap, and the inner flap is pushed into the accommodation space from the pushing opening. The outer flap is separated into two at the parting line by pulling up the outer flap at.

  The push-in opening of the outer flap is formed so that the inner flap can be pushed in by a user's fingertip, and the inner flap is formed so as to be able to be immersed in the accommodation space by the insertion groove.

  An opening lid is provided on each of the upper lid portion (12) and the bottom lid portion (13) of the box body. As a result, after use, the box body can be folded and disposed of when the outer flap of the bottom lid part is separated into two by the separating line as with the upper lid part.

  The separation line is formed by double perforations. Thereby, it can open easily, without forming a big jaggedness in a separation part.

  The present invention forms a separation line that bisects the adhesive part and the non-adhesive part on the outer flap that constitutes the opening lid, and a pair of insertion pieces that are continuous with the separation line and have a pushing opening at the center, and are formed on the inner flap. Since the insertion groove is provided, and the fingertip is inserted from the push-in opening and the outer flap is pulled up, the two effects are obtained.

  Since the outer flap is separated and opened by pulling it up with the fingertip inserted from the push-in opening, it can be opened regardless of the accommodation state of the contents. Therefore, it is easier to open compared to a lid structure in which the outer flap is pushed inside to open. At the same time, since the outer flap is divided into two in a state where it is stuck to the inner flap with an adhesive or the like, no paper scraps are generated at the time of opening.

  Further, according to the present invention, the box body can be disposed in a folded state after use by providing a separation line on the outer flap of each of the upper lid portion and the bottom lid portion of the box body.

  Since the opening lid 12 and the bottom lid 13 have the same structure, the structure of the opening lid 12 will be described below. As shown in FIG. 1, the opening lid 12 bends the end flap 21, bends the inner flap 16 thereon, and further bends the outer flap 17 thereon. The inner flap 16 and the outer flap 17 are sealed with an adhesive.

  An insertion groove 26 is formed in the inner flap 16. The insertion groove 26 is formed by an arc-shaped notch as shown in FIG. The insertion groove 26 is provided on the inner side (the folded base end side) of the sticking portion 23 of the inner flap 16, and is disposed at a position where insertion pieces 27a and 27b of the outer flap 17 described later are inserted. The adhesive part 23 is provided with a glue margin part 24 having a crease (uneven surface) in an area coinciding with the adhesive part 17a of the outer side flap 17, and this crease increases the adhesive strength of the adhesive.

  The said outer side flap 17 is divided into 2 by the separation line 29 by the sticking part 17a and the non-sticking part 17b. A push-in opening 30 is provided in the central portion continuous with the separation line 29, and a pair of insertion pieces 27 a and 27 b are formed on the left and right sides of the push-in opening 30. That is, the outer side flap 17 is divided into the sticking part 17a and the non-sticking part 17b by the separating line 29 and the insertion pieces 27a and 27b continuous thereto, and the pressing opening 30 is provided between the left and right insertion pieces 27a and 27b. Is provided.

  The pushing opening 30 is formed so that a user's finger (for example, forefinger) can be inserted, and the inner flap 16 can be directly touched from the opening. The aforementioned insertion groove 26 is located in the inner flap 16 of the opening 30. Therefore, when the inner flap 16 is pressed from the opening 30 of the outer flap 17, the user's finger can enter between the outer flap 17 and the inner flap 16.
