[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package for a cutter blade, and more particularly to a package for a cutter blade capable of storing the cutter blade after opening.

[0002]

BACKGROUND OF THE INVENTION Conventional cutter blades
10 to 10 sheets are stored in a molding container, and if necessary, one sheet is taken out and used one by one, and the remaining cutter blades are used.
It is stored while being housed in the original molded container from the standpoint of safety.

[0003] Molded containers accommodating cutter blades are sold in a box or the like in a store.

In recent years, various articles are often stored in blister pack-type packaging containers and sold in stores.

[0005] A blister pack type packaging container has an advantage that an article contained from outside can be immediately recognized. On the other hand, a heat-fusing backing sheet is used as a lid of a molded container, and a molded container in which contents are put and a heat container are used. Since the contents are fused, the backing sheet as a cover must be torn in order to take out the contents. Therefore, there is a disadvantage that once opened, it cannot be used as a storage container.

For this reason, a blister pack-type package in which the remaining cutter blades cannot be safely stored cannot be used as the package of cutter blades.

Accordingly, the present inventors have made it easier to display the cutter blade packaging at the store as in the case of the blister pack type packaging container, and as a result of various studies on a packaging body that can be used as a storage container even after opening, the present invention. The present invention has been completed, and an object of the present invention is to provide a package of cutter blades that can be safely stored and stored after opening.

[0008]

SUMMARY OF THE INVENTION The gist of the present invention is to provide a sealant layer on the surface and to provide a notch for display.
A molding container having an outer edge portion, a sealant layer and a layer having heat-fusibility as one surface, and a lid of a laminate having a uniaxially stretched thermoplastic resin layer as at least one layer. The heat-fusible layer of the lid is
Cutter formed by heat fusion with sealant layer at outer edge of molded container
-In the blade packaging bag, the lid and the outer periphery of the molded container
A package for cutter blades, wherein an unsealed portion corresponding to the width of an opening is provided in a heat-sealed portion .

That is, in order to have at least one layer of the uniaxially stretched and oriented thermoplastic resin layer and to easily provide a slit-shaped opening as the lid in the present invention, a part of the lid sealed with the molded container body is provided. because the unsealed portion of the width corresponding to the width of the opening is provided seen hitting to open the package of the present invention which corresponds to the opening width without opening the front tearing in the stretching direction than the unsealed portion From the seal
It is opened in the form of a slit, and the cutter blade can be taken out from here for use, and the remaining lid is heat-sealed to the packaging container, so that it can be used as a storage container for the cutter blade.

The present invention will be further described in detail.

The packaging container of the present invention is made of, for example, a polyvinyl chloride resin, a polyester resin or the like, like the packaging container of the blister pack. The surface has an outer edge portion for heat-sealing with the lid, and the surface has a sealant layer made of polyethylene or the like for heat-sealing with the lid, and has a cutout portion for display. Provide.

One surface of the lid is a sealant layer made of polyethylene or the like for heat-sealing with the packaging container, and the other surface is made of a resin having high strength, for example, polyester, polyamide, polypropylene or the like. In the present invention, the lid is preferably made of a laminate of polyethylene / uniaxially stretched polyethylene / polyester, and the intermediate container is preferably made of a uniaxially oriented polyethylene or polyester film. It is polyethylene.

Next, the present invention will be described with reference to the drawings .
1 is a perspective view of the package according to the present invention, FIG. 2 is a front view, FIG.
Is a rear view, and FIG. 4 is a cross-sectional view.

In the drawing, a forming container 1 has a concave portion 2 for accommodating a cutter blade, an outer edge portion 3 and a cut portion 4 for display. This molding container is molded with polyvinyl chloride resin 6, and the surface thereof is laminated with polyethylene 5 as a sealant layer. The lid is made of polyethylene 5 'as a sealant layer, on which uniaxially stretched polyethylene 7 and polyester 8 are laminated, and heat-sealed leaving an unsealed portion 9 for providing a slit-shaped opening for the container. I'm wearing it. Then, when opening the package according to the present invention, when the package is torn from the unsealed portion, the lid is easily opened in a slit shape to the width of the unsealed portion because the uniaxially stretched film layer is laminated, and other portions are opened. Can be used as a storage container because it remains in close contact with the lid.

[0015] In addition to the concave portion for accommodating the cutter blade, a concave portion for additionally containing a rust inhibitor or a concave portion for accommodating a used cutter blade can be appropriately provided.

[0016]

EXAMPLES Example 1 (a) A polyethylene film having a thickness of 30 μm is bonded to 200 μm of polyvinyl chloride as a sealant layer with a urethane-based adhesive. This material is compression-molded to form a molding container having a width of 30 mm, a length of 120 mm and a depth of 5 mm having a cutter blade accommodating recess in an outer shape of 160 mm in length and 45 mm in width. A hook hole is provided above. On the other hand, 12 μm polyester, 25 μm uniaxially stretched polyethylene, and 30 μm polyethylene are bonded together using a urethane adhesive to form a three-layer lid material film. Five cutter blades were inserted into the concave portion of the molding container, and the lid material film was heat-sealed to the molding container such that the stretching direction of the uniaxially stretched film was parallel to the short width of the concave portion. At that time, an opening is provided as an unsealed part in a part of the sealed part 40 mm below the top of the package.

Example 2 In the same manner as in Example 1, the material of the molding container and the material of the molding container for forming the laminated sheet of the lid were 180 mm in length and 4 mm in width.
5mm outside diameter, length 120mm, width 30mm, depth 52m
m and a length of 20 mm, a width of 30 mm and a depth of 52 mm are provided. A cutter blade is inserted into the former concave portion, and a rust preventive is inserted into the latter concave portion. The lid was heat-sealed except for the part.

[0018]

As described above, in the present invention, it is possible to easily open the package by using the laminated body in which the uniaxially stretched film is laminated as the lid, and it is possible to use it as a storage container even after opening. Further, it is possible to send effects such as display and sale at a store as in the case of a normal blister bag form.
