Garbage bag for expelling animals and preparing method

The present invention relates to a garbage bag for combating harmful animals and a method of manufacturing the same. More specifically, it is possible to minimize the occurrence of odors around the animal because it is not damaged by animals, as well as to keep the surrounding environment clean. The present invention relates to a garbage bag for the elimination of noxious pests and the method of producing the same in a simple and economical manner.

In particular, the present invention includes a post-processing process using ink impregnated with an effective fragrance, such as a letter or symbol printed on a garbage bag, in order to maximize the retention period of the threshold value of the effective fragrance.

In general, garbage bags are containers in which garbage can be accommodated. In recent years, plastic bags are frequently used because they are easy to produce, inexpensive, and convenient to use. If you put the garbage from your home or park in a bag and collect it in a certain place, the cleaning vehicles of each ward will be collected, and before the ward can be collected, various kinds of animals such as cats, dogs, mice, birds and wild animals In order to eat the contents of the garbage bags, the bags are damaged, and the garbage spilled out of the bags not only blows in the wind or causes bad smells, but also causes the transmission of pests by various animals, which is very bad for hygiene. .

Accordingly, Patent Document 1 discloses a garbage bag that can cover the garbage bags with a net to prevent damage to the bags. However, this method does not substantially prevent the access of animals, and in Patent Document 2, any volume of creosote It discloses a composition for combating algae and wildlife prepared by mixing vinegar in a volume of 100 to 200 times, but this is not the case when applied to a garbage bag.

In addition, Patent Literature 3 forms a tie string and a hole at the inlet edge of the garbage bag to easily bind the inlet of the garbage-filled bag, and the outer surface is coated with a naphthalene component to prevent the animal from being approached and damaged by the animal. Disclosed is a garbage bag that prevents, but the process of coating the naphthalene component on the outer surface of the plastic bag is not only complicated, but also has the disadvantage that the naphthalene fragrance is easily volatilized.

In addition, Patent Document 4 discloses a garbage bag containing orange or lemon scents that are avoided by harmful animals. However, continuous animal experiments have shown that the sustaining effect is inferior, and it is effective to detect wild animals to avoid in severe rainy weather. There was a tendency for the retention period of the threshold value of incense to decrease.

Accordingly, the present invention has found that cats, dogs, mice, birds and wild animals can avoid the access of the animals by avoiding eucalyptus, pas, or mixed scents, and moreover, known orange or lemon scents It has been found that the threshold concentration of effective fragrance is longer than that of the present invention, and the present invention has been completed based on this.

Accordingly, an object of the present invention is to provide a garbage bag that can keep the environment clean as well as minimize the generation of odors around the garbage bag is not damaged by animals.

Another object of the present invention is not only to increase the retention period of the effective concentration limit concentration of the sense of smell that the odor of the trash bag is semi-permanent, but also to avoid the wild animals even in heavy rain as well as simple and economical It is to provide a method that can be produced by the method.

Garbage bag of the present invention for achieving the above object is a waste bag made of a plastic resin, it is composed of the addition of 2 to 30% by weight of eucalyptus flavor, pars flavor or a mixture thereof.

The method for producing a garbage bag for achieving the object of the present invention is a plastic bag selected from the group consisting of polypropylene, polyethylene, polyvinyl chloride or ethylene vinyl acetate in the manufacturing method of the garbage bag, the plastic resin is 0.1 After grinding to ˜0.5 mm, 10-30% by weight of eucalyptus, pars, or mixed scent thereof is added in the form of a liquid or solid phase, and the temperature of the resin is 3 to 5 at 50 to 70 ° C. After mixing for minutes, the mixture is characterized by using a resin pelletized.

In the present invention, the pelletization is extruded into the hopper of the extruder maintained at 120 ~ 130 ℃, extruded, and then cooled in a cooling bath maintained at 5 ~ 10 ℃ and cut into 2 to 3 mm size It is done.

In the present invention, printing using an ink impregnated with 2 to 10% by weight of eucalyptus flavor, pars flavor, or a mixed flavor thereof in the text or symbol printed on the garbage bag, or eucalyptus flavor, pars flavor or these It is characterized by spraying a colorless ink impregnated with a mixed flavor of 2 to 10% by weight of the ink on the surface of the bag.

The garbage bag according to the present invention is not damaged by animals, so as to minimize the occurrence of odors around, as well as keep the surrounding environment clean.

In addition, the garbage bag according to the present invention is a semi-permanent emanation of incense, can be a long-term incense even in bad weather during the rainy season. In addition, in the present invention, the garbage bag can be manufactured in a simple and economical manner.

Looking at the present invention in more detail as follows.

In general, plastics that penetrate incense to plastic resins and emit fragrance in moldings formed in various forms are well known (see, for example, Korean Patent Publication No. 1997-0042742).

On the other hand, a garbage bag containing orange or lemon flavor has been disclosed to prevent cats, dogs, mice, or wild animals from approaching (see Korean Patent No. 10-0765499), but detects enough to avoid wild animals in heavy rain. There is a tendency that the retention period of the effective concentration limit value of the fragrance tends to be reduced, and the fragrance itself also has a number of experiments. They found that they had a better effect on getting them to dodge.

In the present invention, 2 to 30% by weight, preferably 10 to 15% by weight, of the eucalyptus flavor, the pasta flavor, or a mixture thereof is added in the process of manufacturing the existing garbage bags. However, coarsely pulverize the resin to disperse incense and add a large amount of incense. In addition, the said effective fragrance may be mixed and used in% of a hit weight as the case may be.

In the present invention, the addition form of the fragrance may be a liquid or solid phase, if the addition amount is less than 2% by weight has little effect of addition, if it exceeds 30% by weight can reduce the physical properties of the garbage bag.

The plastic resin is preferably polypropylene, polyethylene, polyvinyl chloride or ethylene vinyl acetate, and may include any plastic resin that can be molded into a plastic bag.

Looking at the manufacturing method of the garbage bag according to the present invention, first, coarsely pulverize the plastic resin to a size of 0.1 ~ 0.5mm, and then put the plastic resin into the mixer, and then plasticizer, antistatic agent, filler and / or to the resin Other additives, such as dispersants, are added and the fragrance is added when they are thoroughly mixed. After the fragrance is added, the mixture is mixed for 1 to 10 minutes, preferably for 3 to 5 minutes, and then the resin is taken out at a temperature of 50 to 70 ° C.

When the particle size of the plastic resin is pulverized to less than 0.1mm, the physical properties of the plastic resin tend to be inferior, and when the particle size of the plastic resin is exceeded to 0.5mm, the dispersibility of the scent added in the subsequent process tends to be inferior. In addition, when the mixing time is less than 1 minute, the mixing time may be relatively low, so that the dispersion of fragrance may be lowered. When the mixing time is more than 10 minutes, the fragrance may be volatilized during the mixing process, and thus the addition efficiency may be decreased.

In the present invention, the addition of the incense to the garbage bag is not simply the addition of the incense, but should contain the incense in the waste bag evenly in an amount sufficient to combat harmful animals. Therefore, it is very important to properly combine the mixing conditions such as the pulverization of the plastic resin, the addition amount and the addition time of the plastic resin, it is possible to achieve the effect to be obtained in the present invention.

The mixture is then extruded in an extruder and then cooled in a cooling bath and cut into appropriate sizes to produce pellets. At this time, care should be taken to avoid moisture. These pellets are used to form a garbage bag in a conventional manner.

According to the present invention, the post-treatment process is performed using ink impregnated with 2 to 10% by weight of eucalyptus, pars, or mixed scents of ink weight on letters or symbols printed on the garbage bags, so that the effective scent can be long-term, even in severe bad weather. You can create a garbage bag that can last.

In addition, the colorless ink impregnated with the eucalyptus flavor, the parsley flavor, or a mixed flavor thereof in an amount of 2 to 10% by weight may be sprayed onto the surface of the garbage bag according to the present invention to produce a garbage bag.

At this time, if the addition amount is less than 2% by weight has little effect of addition, if it exceeds 10% by weight can reduce the physical properties of the ink.

The trash bags thus produced emit aromas that are avoided by the animals, so that they are not broken by the animals, thereby minimizing the occurrence of odors in the surroundings, as well as keeping the surrounding environment clean.

Hereinafter, the present invention will be described in more detail with reference to the following examples, but the scope of the present invention is not limited to the following examples.

When the temperature of the high-density polyethylene is about 50-60 ° C., 1.5 wt% of a dispersant (LC Wax, Lion Chemical Co., Ltd.) and 0.5 wt% of an antistatic agent (Zn CellFact-A, Malaysian) are added, and when they are completely mixed, liquid eucalyptus flavor (SP-35527 of Seoul fragrance company, SP-35452 of Seoul fragrance company) and mint fragrance (SP-35451 of Seoul fragrance company) are added by 4 weight%, respectively. After adding the fragrance, the mixture was mixed for about 4 minutes, and the resin was taken out at a temperature of 60 to 65 ° C.

The mixture was extruded into a hopper of an extruder maintained at 170 ~ 190 ℃, and then cooled in a cooling bath maintained at 20 ~ 30 ℃ and cut into a size of 2-3 mm to prepare a pellet. At this time, care should be taken to avoid moisture. Using such pellets, a garbage bag was prepared by a conventional method.

Examples 4-6

A garbage bag was prepared by printing letters on the outer surface of the garbage bag with ink impregnated with 3% by weight of liquid eucalyptus flavor (SP-35527 of Seoul perfume company) in the garbage bags according to Examples 1 to 3 above.

Comparative Examples 1 to 3

The same method as in Examples 1 to 3 was carried out except that each was replaced with an orange scent (SP-32740 from Seoul Spice) instead of eucalyptus scent or pars scent.

Comparative Example 4

Commercially available garbage bags were prepared.

Test Example 1

The same food waste, such as fish paste, cod, and fish, was put in a garbage bag according to Examples 1 to 6 and Comparative Examples 1 to 4, and then placed in five places accessible to the animals, and the animals were approached. It was.

As a result, commercially available garbage bags (Comparative Example 4) were all destroyed by animals in the first day of the experiment, and food was out of the bag and was unhygienic, but Comparative Examples 1 to 3 were compared with the garbage bags according to Examples 1 to 6. Were not all broken.

Therefore, the eucalyptus flavor, the parsley flavor, or the mixed flavor and the lemon flavor and the orange flavor could be obtained as a result that animals do not like, and these effective incense were able to obtain the effect of masking the odor of the garbage to some extent.

Test Example 2

With the food on the next day of the test, the surface of the bags of Examples 1 to 6 and Comparative Examples 1 to 3, which were not damaged, was sufficiently sprayed with water and wiped with a dry mop, and the surface of the garbage bag was again wetted with water. Was left and observed for 7 days and 10 days.

As a result, the garbage bags to which orange flavors according to Comparative Examples 1 to 3 were still effective for dogs until 7 days, but some were damaged by cats, and all were damaged until 10 days.

In addition, the garbage bags according to Examples 1 to 3 were not damaged until 7 days, one bag was damaged on 10 days, and the garbage bags of Examples 4 to 6, which were post-processed, were completely damaged until 10 days. There was no.

Therefore, the post-processing treatment as in Examples 3 to 6 was able to obtain the effect of extending the retention period of the limit concentration value of the effective fragrance for a long time even in severe bad weather during the rainy season. In addition, it was found that the eucalyptus flavor, the parsley flavor, or a mixed flavor thereof was more avoided by the animals than the lemon or orange flavor.

In order to experiment with this avoidance, dogs and cats in domestic hospitals were separated, and each of the cages was filled with orange scented waste bags of Comparative Examples 1 to 3 and roasted pork belly in the waste bags of Examples 1 to 3 Each of our corners was separated and thrown separately. As a result, the dog avoided both the trash bags of Examples 1 to 3 and the trash bags of Comparative Examples 1 to 3, but in the case of cats, the trash bags of Examples 1 to 3 have a high degree of avoidability. Obviously, the garbage bags of Comparative Examples 1 to 3 to which the orange flavor was added were found to be avoidable, but the phenomenon of revolving around them was still observed.

Thus, it was observed that eucalyptus, pars, or mixed scents were much more effective in inducing animal avoidance than orange or lemon scents.
