Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention protects the products that are hung and displayed from being contaminated when the products are displayed in a store so that the contents of the products can be sufficiently discriminated. The present invention relates to a display bag with a header that makes it easy to carry the product without having to repackage the product on display when it is brought home, just as it was on display.

[0002]

[Prior Art] A store's sales policy of displaying products at stores and expanding the sales volume by appealing to the eyes of customers has been practiced since ancient times. Although it is considered that there is a problem, when the product is displayed as it is exposed, dust and dirt are often attached when the number of rotations of the product is low, so that a decrease in the product price cannot be avoided. was there.

In order to avoid this drawback, generally, a method has been adopted in which a product is packaged in a transparent bag made of a plastic film which is relatively easily available and then displayed at a store. ..

In this case, as the plastic film, polypropylene is used in consideration of its transparency and strength, air permeability, ink stability at the time of printing, economy and the like.
Along with the use of films of polyethylene, polyester, etc., it is becoming more and more popular to use a laminated film in which several layers are stacked, rather than simply using a single film.

On the other hand, when a product packaged with a plastic film is displayed in a store, the product packaged with a plastic film is often hung and displayed. In this case, transparency is mainly used. Even if you try to display a product packaged with plastic film with a pin hole directly in the square bag made of only the thin plastic film that was made,
Since the vicinity of the pin hole of the rectangular bag made only of thin plastic film is only low in strength,
It is not easy to support the self-weight of the product that is the content,
In order to avoid this, one thick plastic sheet that has been cut so that 4 fingers can be inserted for convenience of carrying is attached to one end of a square bag made of plastic film containing products in advance. On the other hand, the product is displayed at the store such that a bag adhered with an adhesive or a display bag in which both the rectangular bag and the header are adhered by heating in some cases is used. The pin hole that is used to suspend the display bag on the pin that protrudes forward from the wall surface, and the strength of the notch that allows the insertion of 4 fingers to make it easier to hold the product when carrying the display bag For the purpose of increasing the strength, the square bag made of a plastic film is reinforced by strengthening the header that serves as a product hanging hand and a hanging part, as opposed to the square bag made of a low-strength plastic film. Header with a display bag integrated have also been utilized.

However, as described above, the header-equipped display bag, which is adhered to one end of the plastic film rectangular bag with an adhesive, has a defect that it takes too much time because of manual work. In the case of a header-equipped display bag in which both the rectangular bag and the header made of the plastic film described above are bonded by heating, the plastic film is often damaged by the heat effect during heat bonding. The result of adhesion between the two was not so beautiful, and only a low display value header display bag could be obtained.

Further, in addition to the above example, a header provided with a pin hole and a notch capable of inserting four fingers in advance and a square bag made of a plastic film having one end opened are provided. A display bag with a header is also used, in which the product is inserted through the opening of a rectangular bag made of a plastic film that has been integrated and placed integrally with this header, and then the opening is sealed with an adhesive. In this case, the manual work is troublesome and the product selling price is high.
