Description

  The present invention relates to a carton for storing a wrap film used for food packaging or storage at home or for business.

A wrap film or aluminum foil, which is a web used for wrapping food for storage or cooking, is usually rolled into a paper cylinder and stored in a paper carton. The web is pulled out to a desired length, and then cut and used by a saw blade member attached to the carton. Especially in the carton that stores the wrap film, when the film is cut, the remaining film is rewound and wound in close contact, and the end is difficult to see because the film is transparent. There is a drawback that it is difficult to grasp at the time of use, and various proposals have been made to solve this problem. For example, a carton with a hinged cover that can be opened and closed on the top of a carton having a horizontally long opening, and a front surface portion having a smooth surface, an adhesive member, or a cross-linkable cured varnish as a temporary fixing functional member Arrangement or processing is to prevent rewinding by temporarily attaching the cut film end to the temporary fixing functional member by utilizing the self-adhesiveness of the wrap film. However, locking of the wrap film by the temporary fixing functional member applied to prevent rewinding becomes too strong, and the film edge can be peeled off from the locking portion of the carton front plate at the time of the next pulling operation. There is a drawback that it becomes difficult, and on the contrary, irregular tears from the end of the film may occur (for example, see Patent Document 1).

  FIG. 1 is a developed view of the back side of a blank to which a cutting blade of an embodiment of a wrap film storage carton according to the present invention is attached. A carton body 1 on which a paperboard or the like is punched is a front wall 2 and a bottom wall via folding lines 3, a rear wall 4 and a lid top plate 5 are arranged in sequence, a folding plate 8 is provided on a side edge side of the front wall 2 via a folding line, and a lid portion is provided on a side edge side of the lid top plate 5 via a folding line. Although not appearing in the front plate 6 and the figure, an opening piece 7 is continuously provided through a break line. A cutting blade K is attached to the edge of the lid front plate 6 on the side of the opening piece 7 as shown in the figure, and after the assembly of the carton is formed, the opening piece 7 is opened and removed by a break line during use. The cutting edge K is attached to a position where the cutting edge comes out from the edge of the lid front plate 6.

  Usually, the cutting blade in this kind of wrap film storage carton is a band-shaped metal thin plate having a sawtooth-shaped cutting part, and is attached by being crimped to the full width of the edge of the cover part of the carton. The metal thin plate surface of the cutting blade used in the past has a low smoothness. By preventing temporary attachment of the wrap film to the rear surface of the cutting blade after the cutting operation, the temporary thin plate provided on the front wall is used. In the wrapping film storage carton according to the present invention, an adhesive application part M is provided in the center of the longitudinal width of the back surface of the cutting blade K, and the wrapping film is securely locked by the clasp. A smooth surface is formed to provide temporary attachment.
