JPS5929878Y2 - packaging bag - Google Patents

Description

[Detailed description of the invention] This invention makes it easy to see the printed display, make it easy to insert and break the product, and when packaging powder or granular products, it can be placed upright or laid down side-by-side. It relates to a packaging bag that can be polymerized and is also convenient for packaging.The gist of the bag is that it has a transparent bottom plate, has a similar external shape, and has the required printing on the bottom surface. This is because a hard annular plate is polymerized and bonded.

The figure shows an embodiment of the present invention, in which reference numeral 1 denotes a circular bottom plate made of transparent plastic, the upper surface of which has the same outer diameter as the bottom plate 1, and the lower surface of which is printed with paper or the like. A hard annular plate 2 made of is bonded with a solvent or adhesive.

An inwardly bent edge 4 at the lower end of a cylindrical body 3 made of a plastic film (preferably heat-shrinkable) is adhered to the periphery of the lower surface of the bottom plate 1 as appropriate.

The shape of the bottom plate 1 may be square or other shapes.

Unlike conventional bags, this bag is equipped with a hard annular plate 2 at the bottom, so it can be stood up with the top open, making it easy to insert or throw in items, and to accommodate items. They can be appropriately paired and left standing as they are, or they can be laid down side by side and polymerized.

Therefore, it is possible to display a large number of items in an attractive and effective manner.
You can see the contents through the hole in the annular plate 2.
This is convenient because you can see the printed display above.

In addition, with conventional bags, when granular materials such as candy or hail are packaged, unevenness and curvature occur on the entire surface of the bag, making it difficult to see the printing on it, but with the bag of the present invention, at least Only the annular plate 2 at the bottom always maintains perfect flatness, so its printing will not be deformed and difficult to see.

Furthermore, when packaging granular or powdered materials, conventional general bags are irregularly shaped, resulting in a large loss of space and time when packing them into boxes, which is time consuming and undesirable in appearance. However, when packaged with the bag of the present invention, it is convenient because it can be turned upside down and packaged in a close-contact state with ease and style.

Moreover, when taking out the contents, the bottom plate 1 is poked with a sharp object at the hole in the annular plate 2, which has the advantage that the bag can be broken much more easily than a general bag.

Note that the annular plate 2 can also be superimposed on the lower surface of the bottom plate 1.

However, it is convenient to use the annular plate 2 as the upper surface of the bottom plate 1 because the printed surface of the annular plate 2 is protected.
