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. Particularly in a carton for storing a wrap film, the conventional carton shown in FIG. 1 has a hinged cover part that is openable and closable connected to an upper part of the carton having a horizontally long opening, and the tip of the hinged cover part. After cutting out the wrap film for a predetermined length with a carton with a cutter part formed on it, the hinged cover lid is closed and the front cover plate is pressed down, the carton body is pushed down or the wrap film is pulled up to cut It is a form to do. For this reason, the cutter part has a drawback that force is applied in the pulling direction, the cutter part is separated from the front plate of the carton body, and both end portions of the cover lid are lifted up, making it difficult to perform a smooth cutting operation. (For example, see Patent Document 1).

  In the prior art, a wrapping film storage carton that is easy for consumers to use is provided by solving the problem of the cutting operation caused by lifting of the cutting blade portion.

  In order to solve the above-mentioned problems, the invention of claim 1 is characterized in that the front wall, the bottom wall, and the rear wall are arranged in order, and the lid portion ceiling is formed from the upper end of the rear wall of the long box body having both sides fixed by the side walls. A lid front plate extends from the plate, a lid side plate is suspended from both sides of the lid top plate, the lid side plates are respectively joined to the lid front plate, and the lid portion A wrap film storage carton in which a cutting blade is attached to an edge piece of a front plate, and a convex processed portion extending in a width direction in which the cutting blade contacts a part slightly below a position where the cutting edge of the cutting blade contacts the front wall. By making the wrap film storage carton characterized by being provided, the degree of adhesion of the cutter part to the carton front plate in the cutting operation is increased, and the lifting at the both ends of the lid front plate is reduced, so smooth Cutting operation is possible.

  As described above, the wrapping film storage carton according to the present invention increases the degree of adhesion between the wrapping film and the cutting blade and improves the degree of adhesion between the wrapping film and the cutting blade by the convex processing portion provided slightly below the cutting edge of the cutting blade that contacts the front wall. Since lifting is reduced also at both ends of the plate, a smooth cutting operation of the wrapping film becomes possible. Further, since the convex surface processed portion is provided over substantially the entire width of the front wall, deformation of the front wall such as bending is prevented, and the carton can be used stably.

The present invention will be described in detail below with reference to the drawings.
FIG. 1 is a development view of an embodiment of a wrap film storage carton according to the present invention. FIG. 2 is a perspective view showing the assembled and used state of the embodiment. FIG. 3 is a cross-sectional view of the same embodiment when the film is cut.

  FIG. 1 is a developed view of a blank equipped with a cutting blade of an embodiment of a wrap film storage carton according to the present invention as viewed from the back side. The wrap film storage carton 1 for punching paperboard or the like is A wall 2, a bottom wall 3, a rear wall 4, and a lid top plate 5 are arranged in sequence, a folding plate 8 is disposed on the side edge side of the front wall 2 via a folding line, and a folding line is disposed on the side edge side of the lid top plate 5. The lid front plate 6 is connected to the opening portion, and the opening piece 7 is connected to the opening portion 7 through the broken 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. The front wall 2 is provided with a convex surface processing portion 14 extending in the width direction where the cutting blade K abuts slightly below the position where the cutting edge of the cutting blade K abuts when the wrap film F is cut. Convex surface processing is performed at the same time in the carton punching process, and a belt-like protrusion having a predetermined width is formed on the carton surface, and the protrusion dimension in the thickness direction is substantially equal to or less than the thickness of the cutting blade K. desirable.

  Auxiliary overlapping plates 10, 10 ', side walls 9, 9', heavy weights are respectively connected to both ends of the front wall 2, bottom wall 3, rear wall 4, lid top plate 5 and lid front plate 6 via folding lines. The plywood 11, 11 ′, the lid side plates 12, 12 ′, and the lid bonding pieces 13, 13 ′ are continuously provided. The length of the side walls 9 and 9 'is substantially the same as the short width of the front wall 2 and the rear wall 4, and is not particularly limited in the carton for storing a wrap film according to the present invention. The length of 10 'and the overlapping plates 11, 11' is shorter than the length of the side walls 9, 9 ', and the length of the lid front plates 12, 12' is about two thirds of the length of the side walls 9, 9 '. Further, the length of the lid bonding pieces 13 and 13 ′ is shorter than the short width of the lid top plate 5.

  FIG. 2 is a perspective view showing the assembly and use state of the embodiment, and is connected to both the front wall 2 and the rear wall 4 raised from the bottom wall 3 and both ends of the front wall 2 and the rear wall 4. The auxiliary polymerization plates 10, 10 ′ and the polymerization plates 11, 11 ′ are bent and polymerized, and are formed into a long shape comprising side walls 9, 9 ′ that are connected to and raised from both ends of the bottom wall 3. The lid top plate 5 and the lid front plate 6 that are connected to the upper side of the rear wall 4 are bent, and the lid portions that are connected to both ends of the lid front plate 6 are also attached. Cover side plates 12 and 12 ′ connected to both ends of the lid top plate 5 are bent and glued to the combined pieces 13 and 13 ′, respectively, and a covering lid that covers the opening of the elongated box body is provided. Is formed. The unsealing piece 7 connected to the side edge side of the lid front plate 6 via a break line is removed by a peeling operation at the time of opening, and thus illustration is omitted.

  FIG. 3 is a cross-sectional view at the time of film cutting in one embodiment, and the wrap film F pulled out to a desired length is covered with the lid top plate 5 and the end by closing the cover lid as a previous stage of cutting. Since it is in a state of being sandwiched between the front plate 6 of the lid portion with the cutting blade K attached to the edge and the front wall 2, the convex surface processing portion 14 is in a position to receive the cutting edge of the cutting blade K, so that the wrap film The degree of adhesion between F and the cutting blade K can be increased, and the wrapping film F can be cut smoothly. Moreover, since the convex surface processing part 14 is given to the substantially full width of the front wall 2, it has the reinforcement effect which prevents deformation | transformation of the bending etc. of the front wall 2 together.
