The present invention relates to a garbage bag drawn with a hidden picture. In particular, the present invention is to prevent the use of forged garbage bags by drawing a hidden picture that can be easily distinguished when you want to determine the authenticity of the garbage bag without the naked eye when using it in everyday use garbage bag It's about a garbage bag with a hidden picture.

In order to improve the unreasonable way of imposing the same amount of waste collection fee on everyone who produces and discharges the waste regardless of the amount of waste, there is a nation-wide waste-based system that can bear the waste collection fee according to the waste amount. The garbage collection fee is replaced by the price of garbage bags.

The amount of general waste generated in the whole country is about 60,000 tons per day, and the price of garbage bags used for the discharge of non-recyclable household waste reflects the collection and transportation of garbage, the production and sales profits of garbage bags.

Garbage bags are divided into household, business, business, etc. according to the place of use, and have different capacities according to the place of use. Among them, household garbage bags are 5, 10, 20, 30 and 50 liters, and 20, 30 liter garbage bags are the most prevalent.

The production specification of the pay-as-you-go garbage bag is determined by the group standard standard approved by the Director of Small and Medium Business Administration, and is produced by a designated garbage bag supplier according to the procedure and supplied to local governments such as city halls, county offices, ward offices, etc. Keep records to manage the distribution and sale of garbage bags.

As described above, the price of garbage bags is determined by the local government that manages the distribution of garbage bags according to the capacity of the garbage bags. Since a large amount of garbage bags are used every day throughout the country, they are not properly registered according to a certain procedure. Increasingly, unfair traders make and sell garbage bags.

As such illegal production and sales increase, the basic social order is dissipated, the profits from the sale of garbage bags by local governments are reduced, and the cost of shortages is caused due to significant obstacles to the progress of the clean environment work and related projects. Should be covered by the national tax.

The upper part of the commercially-available garbage bags is printed with "garbage bags (20 liters)" at the upper part, and the middle part is the area where the garbage bags can be used or the types of garbage that can be put in the garbage bags and garbage. Information on the time to throw away is indicated, and at the bottom, information about the municipality that manages the distribution of the garbage bag and information about the manufacturer of the garbage bag is indicated.

As described above, since the information printed on the surface of the garbage bag is printed in a solid color such as dark blue or black, it can be easily forged, and even if the fake garbage bag is sold and used in the market, it is almost impossible to discriminate illegal manufacturing, It is very difficult to block sales and use.

Therefore, in the related art, a technology for printing a cancer cover for identifying the authenticity of a garbage bag with the cancer approval number on the surface of the garbage bag with the same color paint on the garbage bag has been developed. There is a high possibility of illegally manufacturing and selling garbage bags because they are easy to steal because they are used.

As described above, the present invention for preventing illegal manufacture and sale of garbage bags draws invisible hidden pictures to prevent illegal manufacture and sale of garbage bags, while stealing hidden pictures. In order to do so, it is necessary to have a separate facility and to invest a lot of money.

Garbage bags drawn with a hidden picture according to the present invention for achieving the above object, the local government and garbage bags that manage the name of the bag, how to use the garbage bag and distribution of garbage bags on the surface of the synthetic resin bag In the garbage bag is a hidden picture is drawn with information about the manufacturer to manufacture, In the process of manufacturing the synthetic resin bag is formed by pressing the surface of the synthetic resin bag with a pressing projection while applying a heat of 50 ~ 70 ℃ It is characterized by a picture hidden by the groove.

In addition, in the present invention, it is preferable that the pressing protrusion is formed on the surface of the metal pressure roller, and a rubber roller is installed to correspond to the pressure roller.

Hereinafter, the present invention will be described in detail.

1 is a perspective view of a garbage bag with a hidden picture according to the present invention, Figure 2 is a front view of a garbage bag with a hidden picture according to the present invention, Figure 3 is a main part of the garbage bag disclosed in Figures 1 and 2 4 is a cross-sectional view showing the main part of the garbage bag disclosed in FIGS. 1 and 2, and FIGS. 5 and 6 are schematic views showing an installation state of a pair of rollers for drawing a hidden picture in the garbage bag. .

In the garbage bag with a hidden picture according to the present invention, as shown in FIGS. 1 to 3, the name of the garbage bag “20 garbage bags” is marked on the upper end portion 12 of the synthetic resin bag 10. In the middle part (13), information on the area where the garbage bag can be used or the type of garbage that can be put in the garbage bag and the time to throw away the garbage is indicated. Information about the municipality it manages and the manufacturer of the garbage bag is displayed.

In addition, the surface of the synthetic resin bag 10 is a hidden picture 11 of various patterns such as stars made of a plurality of grooves 20 (not actually seen, but is shown as shown in the drawings to explain the present invention.) This hidden picture 11 is not easily seen because it is made of grooves formed by stimulating the surface of the synthetic resin bag 10 with a pressing protrusion as shown in FIG. In particular, since the groove 20 does not penetrate the synthetic resin bag 10, moisture is not absorbed into the synthetic resin bag 10.

5 and 6 show a process of manufacturing a synthetic resin bag 10 and drawing a hidden picture 11 in the synthetic resin bag 10.

First, when the vinyl raw material for producing the bag fabric 15 into the extruder of the vinyl maker, the vinyl raw material melts through a cylinder with a screw. The molten vinyl raw material is molded into a cylindrical housewife through a building table, and then pressed onto a winding shaft through a plurality of rollers.

In particular, since the pair of rollers 16 and 17 as shown in Figs. 5 and 6 is installed between the building table and the winding shaft, the envelope fabric 15 passes between the pair of rollers 16 and 17. On the surface, a hidden picture 11 consisting of a plurality of grooves 20 is drawn.

Here, in order to draw the hidden figure 11 which consists of grooves in the bag fabric 15 with the pressure protrusion 18 of the pressure roller 17, various patterns of pressure protrusions 18 are formed in the surface of the pressure roller 17. FIG. The surface of the rubber roller 16 should be covered with rubber 19 made of a material that can be inserted into contact with the pressing protrusion 18 of the pressure roller 17. The groove should be accurately formed and the shape of the groove should be There must be a heat source that heats the envelope fabric 15 so that it can be maintained for a long time.

Preferably, the heat source for heating the envelope fabric 15 has a temperature of 50 ~ 70 ℃. In this case, as the heat for heating the bag fabric 15, the residual heat of the heat applied to the extruder of the vinyl making machine may be used, or heat generated from a separate heater or the like may be used.

In particular, the installation position of the pair of rollers 16 and 17 for drawing the hidden picture 11 may be determined depending on whether to use residual heat as a heat source or a separate heat source such as a heater.

Therefore, according to the present invention, it is possible to prevent the illegal manufacture and sale of garbage bags by providing a separate facility for theft of the hidden picture drawn on the surface of the garbage bag and investing a lot of money.
