Description

  The present invention relates to a volume-reducible carton that can be stored by reducing the volume of a carton in a state in which half or a part of a stored product is stored as it is after use.

  Conventionally, in a carton that stores two individually wrapped roux such as curry and stew, when taking out one and storing it in a refrigerator or the like while the remaining one is stored in the carton, It was stored in a size with no extra space, or the extra space was folded appropriately, or cut out with a scissors and stored.

  However, storing the carton in a state where one of the above-mentioned contents is taken out takes a wasteful storage space, and the carton in which the extra space is folded is restored to the original folded part during storage. In addition, a carton from which extra space has been cut off with a scissors sometimes causes the contents stored from the cut end to protrude or fall during storage or handling.

  The present invention solves the problems of the conventional carton described above. When a plurality of individually packaged contents are stored and the remaining part is taken out and stored together with the carton, the carton becomes bulky. In addition, the present invention provides a carton capable of volume reduction that prevents stored contents from protruding or dropping during storage or handling.

  That is, the first aspect of the present invention is a rectangular carton having a vertically long rectangular external appearance formed by folding a blank, and includes a left side plate, a front plate, a right side plate, a back plate, and an outer top plate. An inner top plate, an outer bottom plate, and an inner bottom plate, and when opening and using a plurality of individually wrapped contents, an opening provided at a substantially central position in the lateral direction of the upper end portion of the back plate. The inner top plate is partially broken in a state where the mouth piece portion is pushed through and the opening mouth piece portion is adhered to the outer top plate, and the outer top plate, the inner top plate, and the left and right side flaps After taking out a part of the contents to be stored, the left and right side plates are folded inward in the middle in the horizontal direction, and the front plate and the back plate are overlapped to place the back plate inside. Folded to the middle in the vertical direction, the difference provided at a predetermined position below the back plate To see the locking unit, a volume reduction can carton, characterized in that the locking insert the locking piece portion which is disposed in a predetermined position of the outer top panel.

According to a second aspect of the present invention, the carton blank is formed by sequentially connecting a left side plate, a front side plate, a right side plate, a back plate, and an adhesive plate from the left side through a vertical crease line. In addition, flaps are respectively connected to upper and lower ends of the left side plate and the right side plate via a horizontal crease line, and an outer top plate is attached to the upper end of the front plate via a horizontal crease line. The outer bottom plate is connected to the lower end of the front plate via a horizontal crease line, and the vertical width is smaller than the outer top plate to the upper end of the back plate via a horizontal fold line. An inner top plate is continuously provided, an inner bottom plate having a smaller width in the vertical direction than the outer bottom plate is connected to the lower end of the back plate via a horizontal crease line, and the flap is connected to the left side plate and the upper end. The folding position of the front plate and the back plate of the left side plate from the upper end of the flap at the horizontal center position A vertical crease line is provided up to a position corresponding to, and two oblique folds opened downward from the lower end of the crease line to the left and right are provided at predetermined positions, and at the center position of the outer top plate connected to the upper end of the front plate. The locking piece is formed by providing a notch of a predetermined shape downward, and the right side plate is connected to the right side plate and the upper end of the right side plate from the upper end of the flap at a central position in the lateral direction of the flap. A vertical crease line is provided to a position corresponding to the folding position of the face plate and the back face plate, and two oblique folds that open downward from the lower end of the crease line to the left and right correspond to the two oblique folds of the left face plate. A lateral crease line is provided at a position where the back plate is folded with the front plate, and the lower fold line on the right side of the right side plate is connected to the lower end of the right side plate in parallel with the lower side crease line. Provide a horizontal crease line, and A perforation line is provided at the center position in the direction to form an opening piece, and a lateral cut line is provided at the lower position where the engagement piece of the outer top plate of the back plate is inserted and locked. And forming an oblique crease line corresponding to the oblique crease line on the left side of the left side plate by connecting to the right end of the lower lateral crease line provided in parallel to the back plate. The volume-reducible carton according to the first aspect of the invention is characterized in that a notch is provided at a predetermined position at the center upper end of the inner top plate.

  The volume-reducible carton of the present invention has a plurality of contents to be individually wrapped and has an opening piece provided by a perforation line at a substantially central position in the lateral direction of the upper end of the back plate when used. Push and move to the front side of the front plate, with the opening piece part stuck to the outer top plate, with the opening piece piece stuck to the outer top plate, partially breaking the inner top plate Open the outer top plate, the inner top plate, and the left and right side flaps, take out the upper contents to be stored, and horizontally store the left and right side plates when storing the remaining carton in a refrigerator etc. Folded inward with a vertical crease line and an oblique crease line in the middle, flattened, overlapped the front and back plates, folded back to the middle in the vertical direction with the back plate inside, provided below the back plate Insert the locking piece provided on the outer top plate into the inserted locking part. It is possible to stop. This reduces the extra space in the carton, prevents the carton from becoming bulky when storing the carton, and prevents the stored contents from sticking out or falling off during storage or handling. Is done.

  Next, an embodiment of the volume-reducing carton of the present invention will be described in detail with reference to the drawings.
