DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a covering film opening structure for easily opening an article packed with various film materials such as a wrap film and a shrink film.

[0002]

2. Description of the Related Art Various forms of foodstuffs are handled in supermarkets, convenience stores, prepared food stores, lunch boxes, and the like, but are packaged in containers such as plastic trays and wrapped in a wrap film. Many are displayed and sold in the form.

[0003] Packaging using a wrap film does not require an auxiliary material for sealing such as an adhesive or an adhesive tape, or a sealing device, so that the packaging operation is easy, the sealing property is relatively good, and packaging from outside can be performed. In recent years, its use has been increasing because of its merits such as easy visibility of objects. In particular, most food products manufactured (cooked) and packaged at retail stores are packaged with wrap film.

[0004] When unwrapping an article packaged with a wrap film, a search is made for an overlapped portion between the edges of the wrap film located at the bottom of the product or the like to find the edge of the wrap film, and this portion is picked with a finger. The entire wrap film is peeled off by pulling it off.

When it is difficult to find the peripheral portion of the wrap film, a cut is made in a part of the wrap film using a knife or the like, and the wrap film is cut open by applying a force so as to widen the cut portion. However, when the blades are not close at hand, the wrap film may be forcibly torn by grasping a part of the wrap film with both hands and strongly pulling the wrap film left and right.

[0006] On the other hand, juice containing a pack is 12 to
Approximately 20 bottles are packed together and packed into a shallow cardboard box without a lid that can accommodate the lower half of the pack, and the juice and the cardboard box with these packs are shipped in a state of being wrapped with shrink film. . In this case, the shrink film is formed of a material such as polypropylene, polyethylene, or vinyl chloride, which has high strength and is not broken or cracked by an impact during transportation.

Therefore, when displaying the packaged juice delivered in such a package form at a store or the like, the upper surface of the shrink film is cut off with a cutter knife or the like, and then the packed juice is taken out of the cardboard box. ing.

[0008]

Since the wrap film is a thin material and strongly adheres to each other at the overlapping portion of the wrap film, it is surprising to find the peripheral portion of the wrap film by searching the overlapping portion. Difficult,
In particular, it is a difficult task for a clumsy person, a handicapped person, a person with poor vision, and the like.

[0009] On the other hand, the opening method of making a cut in the wrap film using the blades cannot be executed when the blades are not close at hand. In addition, the opening method of tearing the wrap film by hand is not only not possible for children and elderly people with weak hands, but if the wrap film is torn by mistake, the contents may pop out at the moment of tearing, Some wrap films are difficult to cut unless they are in a certain direction, so tips and procedures are required to open the package smoothly.

Further, when taking out a packaged juice or the like delivered in a state of being packaged with a cardboard box and a shrink film at a store or the like, it is impossible to tear the shrink film with just enough force to pull the left and right fingertips. Therefore, as described above, the upper surface of the shrink film is cut off using a cutter knife, etc., but the cutting edge of the cutter knife accidentally touches the pack during cutting work, scratching the surface or tearing the pack itself There is.

An object of the present invention is to provide a cover film opening structure which is easy to manufacture and can be easily opened without using tools such as blades.

[0012]

In order to solve the above-mentioned problems, a cover film opening structure according to the present invention comprises a penetrating portion formed on a covering film for covering an article to be packaged, and a sticking portion at a position covering the penetrating portion. And a tension piece attached thereto. With such a configuration, when the peripheral portion of the tension piece is picked with a finger and peeled off from the coating film, when the tension piece is peeled off the position of the penetrating portion of the coating film, the penetration portion becomes the coating film. As a part of the coating film around the penetrating portion is pulled while being attached to the tensile piece, the coating film is torn with a certain width as the tensile piece is pulled. Therefore, without using tools such as blades,
The coated film packaged article can be easily opened.

[0013] The coating film opening structure of the present invention comprises:
It is characterized by comprising a tension piece adhered to a part of the surface of the film covering the article to be packaged, and a penetrating portion formed through the tension piece and the coating film. With such a configuration, as described above, the peripheral portion of the tension piece is picked with a finger and peeled off from the coating film, so that the coated film packaging article can be easily opened without using a tool such as a blade. It becomes possible.

Here, it is preferable to attach a sealing material covering the through portion to the surface of the tension piece. As a result, the passage of air and moisture can be prevented, so that the sealing property of the covering film can be ensured.

[0015] The former structure of opening the covering film is only required to form a penetrating portion at an appropriate position of the covering film covering the article to be packaged, and to attach a tension piece so as to cover the penetrating portion. Is easy and does not impair the sealing property of the coating film. Further, in the latter case of the covering film opening structure, it is only necessary to form a penetrating portion penetrating the tension piece and the covering film after attaching the tension piece to an appropriate position of the covering film covering the article to be packaged. The shape of the penetrating portion is preferably a pinhole shape or a circular shape that is easy to process,
Depending on the material, thickness, strength, crack direction, etc., of the coating film, it may be in the shape of an arc, a half moon, a sashimi, a polygon, a straight line, a curved line, a cross line, a radial line, or a combination thereof. Therefore, it is possible to obtain the opening workability suitable for the type and use of the article to be packaged.

By providing a non-adhered portion on at least a part of the periphery of the tensile piece adhered to the coating film, the non-adhered portion can be picked up by a finger and peeling of the tensile piece can be started. Opening work is further facilitated.

By forming the penetrating portion and the tension piece at a plurality of locations, the number of cuts generated in the coating film increases, and when the tension piece is peeled off, a cut always occurs from any of these penetrating portions to ensure coating. Since the film is torn, mistakes in opening can be eliminated.
