Description

Easy open bag with cutting line {Pack with cutting line which can be easily opened}

The present invention relates to a bag that can be easily opened by forming a cutting line. More specifically, by attaching two or more films in a layered manner to cut a cut line in only one layer of a bag made to accommodate the contents of confectionery, baking, gum, ramen, etc., and pulling the bag along the cut line, Normally, the film layer without cutting lines is formed so that the bag can be easily opened when necessary while maintaining hermeticity and airtightness.

There are many ways to easily open a bag such as sweets, but nowadays, a thin band-shaped tape is adhered to the back of the bag along the circumference of the bag and pulled out when the bag is opened. How to open it. This method is used a lot when opening the outer film of cigarette packs or the outer bag of gum.

The method of opening the bag using the tape-shaped tape described above should not only be such that the material of the bag can be easily torn like paper or thin film, but also can not guarantee complete airtightness and tightness, so that the contents are completely blocked. There is a disadvantage that it is not suitable for the storage of the contents that can be deteriorated by contact with air.

Accordingly, an object of the present invention is to provide an easy-opening bag that can be easily opened by overcoming the problems of the prior art while maintaining airtightness and forming a cutting line suitable for sealing the contents.

Overview of the devise

Bags for storing confectionery, baking, gum, ramen and the like are often formed by laminating (laminating) two or more thin films.

Films used to make the encapsulation include cellophane film, polyethylene film, LLD PE (Linear Low Density Polyethylene), CPP (Casting Polypropylene) film, aluminum foil and polypropylene film.

An advantage of forming a bag by stacking two or more films is that it is possible to make a bag suitable for storage according to the type of contents to be stored taking advantage of the characteristics of each film.

For example, a polyester film having strong surface strength and excellent heat resistance is used for the outer skin layer in contact with air, and an intermediate layer is made of aluminum foil having excellent airtightness, and a sterilized and antimicrobial film is used for the inner layer in contact with the contents. By doing so, it is possible to make a bag with all the various characteristics.

Therefore, various kinds of bags can be produced by laminating an appropriate film layer according to the nature of the contents contained in the bags.

The object of the present invention is to provide an encapsulation that can be easily opened and normally maintained hermeticity and hermeticity by using the fact that the encapsulation is formed by stacking two or more films.

An overview of the present invention is shown in FIGS. 1A and 1B.

1A is a schematic view of the present invention, FIG. 1B is an enlarged view of a portion C, and FIG. 1C is an enlarged cross-sectional view of a portion A-A. The thickness t of the bag is exaggerated for the convenience of understanding the design.

In FIG. 1A, three layers of films are laminated, and the cutting line 10 is cut out on one of the laminated films, for example, by drawing the cutting line 10 only in the outer skin layer and pulling the distal end 11 of the cutting line in the arrow direction 13. It can be easily cut along. The hatched portion 12 of FIG. 1C shows a cross section of the cutting line.

Before opening the bag, airtightness and airtightness are maintained by the remaining film layer where no cutting line is formed.

The type of cutting line may vary depending on the use of the bag and the nature of the contents, an example of which is illustrated in FIG. 5.

Example 1

Figure 2a is one embodiment of the present invention, showing that the cutting line 10 is formed in a single line on the top or bottom of the bag 20.

In this embodiment, the incision 14 is formed in advance in the distal end 11 of the cutting line in order to more easily open the bag. In order to form the cutout 14 in advance, it is preferable that the distal end 11 of the cutting line is a joining part 15 in which both sides of the bag are joined to seal the bag 20.

2B is an example in which opening tape 30 is attached to an end portion of a cutting line to facilitate opening. In this case, the adhesive strength between the opening tape 30 and the bag should be greater than the tensile strength of the film layer at the time of opening the bag. In addition, it is desirable to use a color that contrasts with the color of the bag so that the color of the tape can be easily found in use.

Example 2

3A and 3B illustrate a second embodiment of the present invention, and a cutting line 10 is formed in a band-shaped double portion of a portion of the bag 20 to open the bag by pulling the end portion 11 thereof. It is to be done.

Fig. 3B shows that the opening tape is attached to the distal end 11 of the cutting line. In this embodiment, as in the case of Example 1, the distal end 11 of the cutting line was used as the joint 15 on both sides of the bag. An incision was made to facilitate.

Figure 4a is an example of laminating the film in three layers and each film layer is a cellophane film, polyethylene (Polyethylene) film, LLD PE (Linear Low Density Polyethylene) film, CPP (Casting Polypropylene) film according to the use of the bag, the nature of the contents It can be variously configured with a polyester film, aluminum foil and the like.

4B illustrates an example in which an aluminum metal layer 40 is inserted into an intermediate layer of a film layer stacked in three layers. By inserting the aluminum metal layer, the effect of shading can be obtained, and the airtightness of the encapsulation is also excellent.

In Example 1 and 2, the cutting line 10 was formed in the outer skin layer.

According to the present invention, it is possible to easily open a bag by pulling a bag along a cutting line by drawing a cutting line only in one layer of a bag formed by stacking two or more films, while maintaining airtightness of the contents. There is an effect that can provide a bag that can ensure the sealability.
