Description

Packaging Bag {Packaging Bag}

The present invention is designed to facilitate the carrying of the bag by attaching a packing bag, in particular a carrying handle, and to install the zipper on the top edge and / or bottom edge of the bag so that the bag can be opened and closed quickly and easily. It's about the turret.

As an example of a general packaging bag, it is proposed that a viewing window made of a transparent synthetic resin is provided in a bag made by laminating a large number of papers. Since the packaging bag is made of paper as a main material, the manufacturing cost is not only expensive, but it is troublesome to separate the main paper and the synthetic resin as the material of the viewing window at the time of collection for recycling.

In addition, as another example of the packaging bag, it is proposed that the entire bag is made of a synthetic resin material so that the consumer can easily see the contents. Since the packaging bag made of synthetic resin is usually made of a single layer of synthetic resin, its toughness is relatively low, and since it is not equipped with a separate handle for transportation, it is inconvenient for transportation, and food, grain, powder products, etc. When the bag containing the contents of is laminated in the vertical direction, the bag tends to slip due to the low coefficient of friction of the synthetic resin material.

Therefore, an object of the present invention is to improve the toughness by making the packaging bag made of a double-layer transparent synthetic resin, and to allow the consumer to easily check the contents of the bag, and also to carry the bag by attaching a separate carrying handle to the bag. And the non-woven fabric having a high coefficient of friction on one side of the bag to make it easy to handle, even when the bag containing the contents such as food, grain, feed, and powder products is loaded in the vertical direction, It is to provide a packaging bag that does not fall.

The packaging bag of the present invention for achieving the above object has a double-layer cylindrical bag body member consisting of an inner layer sheet and an outer layer sheet, the top edge of the bag body member is sealed after the insertion of the carrying handle member. It is done.

The carrying handle member is characterized by having a horizontally elongated bar that is inserted into and attached to the upper edge of the bag body member and a handle protruding upward from an approximately central portion of the bar.

The carrying handle member is made of synthetic resin.

Cylindrical bag body member is provided with a seam in the vertical direction, the seam is characterized in that the inner and outer tapes are bonded to the inner and outer sides, respectively.

The inner and outer tapes are made of a nonwoven fabric having a high coefficient of friction, respectively.

The inner sheet is made of linear low density polyethylene (LLDPE), the outer sheet is characterized in that the material is made of one material selected from nylon, polyethylene terephthalate (PET), or linear low density polyethylene (LLDPE).

The upper edge of the bag body member is sealed by heat fusion after inserting the carrying handle member, characterized in that the lower edge of the bag body member is sealed by heat fusion.

A zipper is attached to the upper edge and / or lower edge of the bag body member.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.

Figure 1a is an exploded perspective view of a packaging bag according to a first embodiment of the present invention, Figure 1b is a front view of the completed packaging bag.

As shown in FIG. 1A, the packaging bag of the present invention forms a cylindrical bag body member 10 made of a sheet material in which an inner layer sheet 10a and an outer layer sheet 10b of synthetic resin are laminated. That is, by attaching the inner and outer surfaces of the seam portion 10e extending in the vertical direction of the bag body member 10 to the inner tape 30a and the outer tape 30b, respectively, the cylindrical bag body 10 having the upper and lower openings is opened. ) Can be formed. Any of the tapes having sufficient bonding strength can be used as the inner and outer tapes 30a and 30b. However, it is preferable to use a tape made of a nonwoven fabric having a high coefficient of friction.

The upper edge 10c of the cylindrical bag body member 10 thus formed is fitted with the carrying handle member 20 and then sealed by thermal fusion, and the lower edge 10d is also sealed by thermal fusion. The carrying handle member 20 is a handle that protrudes upward from a substantially horizontal bar 20b and a central portion of the bar 20b which are inserted into and attached to the upper edge 10c of the bag body member 10. 20a is provided. In addition, the carrying handle member 20 is preferably made of synthetic resin so that it can be attached to the upper edge 10c of the bag body member 10 by thermal fusion.

FIG. 2 is a partially enlarged perspective view showing the packaging bag of FIG. 1B from the carrying handle 20 side, wherein the bag body member 10 including the inner sheet 10a and the outer sheet 10b is a seam 10e. It is well illustrated that the inner tape 30a and the outer tape 30b are attached to the inner and outer surfaces thereof to form a cylinder. In addition, the drawing shows that the bar 20b of the carrying handle member 20 is attached to the upper edge 10c of the bag body member 10 by heat fusion. Reference numeral 20a denotes a handle formed in a semicircle.

The inner sheet 10a forming the bag body member 10 is made of linear low density polyethylene (LLDPE), and the outer layer sheet 10b is made of nylon, polyethylene terephthalate (PET), or linear low density polyethylene (LLDPE). It is preferable to make from one material selected.

3A to 3C are front views of the packing bag having the zippers 40 attached to the top and / or bottom edges of the bag according to another embodiment of the present invention. The zipper 40 may be attached by sealing or heat fusion according to its material. When the material of the zipper is synthetic resin, the zipper 40 may be attached by a heat sealing method. desirable.

As described above, the present invention can provide a packaging bag with improved toughness compared to a packaging bag made of a conventional single-layer synthetic resin by making the packaging bag with a double-layer transparent synthetic resin.

In addition, the present invention can provide a packaging bag that is easy to carry and handle the bag by attaching a separate carrying handle to the bag.

In addition, the present invention, by attaching a non-woven tape having a high coefficient of friction to one side of the bag, even if the bag is placed in the vertical direction, the bag of the upper layer does not slip and fall, the nonwoven tape itself is tough There is an effect that can provide a packaging bag to serve to further improve the.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection of the present invention should be defined only by the attached utility model registration claims.
