Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage bag, more specifically, a synthetic resin sheet containing an odor component disliked by small animals such as dogs and cats, which is less likely to be inadvertently broken by the small animals. Regarding garbage bags.

[0002]

2. Description of the Related Art The above-mentioned garbage bags are mainly used for storing and speculating raw garbage generated in daily life at home, and are generally put out at designated places. It is used when collecting things with a cleaning car or the like, but a conventional garbage bag formed of polyethylene is often eaten up by small animals such as dogs and cats, and is often unfavorable in terms of hygiene and aesthetics.

Therefore, in order to solve such a situation, a dust bag formed of a synthetic resin sheet containing an odorous component repelled by small animals has been proposed. this is,
For example, as shown in JP-A-5-77903,
Odor components such as menthone, menthol, limonene, α
-Pinene, 3-methylcyclopentanone, and a sheet of synthetic resin containing at least one of cyclopentanone.

[0004]

However, the garbage bag adopting the above-mentioned odor component is a peculiar one (a rotten odor of eggs) that the original odor of the odor component is repelled by humans. Therefore, it has been found that this peculiar odor is emitted even in the manufacturing process, in the warehouse before shipment, in the store or in each home, and therefore it is not always preferable in practical use.

Therefore, the present invention was developed in order to solve these conventional problems, and the object of the invention described in claim 1 is to avoid the conventional repellent components for small animals such as dogs and cats. While performing the same effects as those containing
It is to provide an improved litter bag that is at least not desirable to humans, but rather desirable.

An object of the invention described in claim 2 and claim 3 is to enable efficient production while successfully achieving the object of the invention described in claim 1.

The object of claim 4 is to further provide a high added value, a high productivity without waste, and a low price.

[0008]

In order to achieve the above object, the garbage bag according to the invention of claim 1 contains at least one of lemongrass oil and creosote as an odor component. It is formed of a synthetic resin sheet.

Preferably, claim 2 or claim 3
As described above, the lemon grass oil and the creosote are contained in the range of 0.02 to 0.3% by weight, respectively.

Furthermore, for the purpose of efficiently exhibiting repellent action against both dogs and cats, high value-added, high productivity with no waste, and cost-effective provision. As a synthetic resin sheet containing lemon grass oil in the range of 0.08 to 0.2% by weight and creosote in the range of 0.08 to 0.2% by weight. You can also

The lemongrass oil is obtained by squeezing the skin of lemon, or leaves the leaves of the lemon raw or partially dried and steam-distilled, and contains 80% or more of citral. to another, limonene, C ₈ - aldehyde, linalool, include geraniol, etc., there is a strong aroma of lemon odor.

Creosote is a mixture of phenols obtained from Moctar, and as the raw material tree, beech, oak, maple, pine and the like are used.

The addition amount of the lemongrass oil used in the present invention is in the range of 0.02 to 0.3% by weight.
Even if it is added in an amount of 0.3% by weight or more, the repellent effect cannot be expected any further, and it is economically unfavorable, and moreover, an undesired odor is generated in the dust bag manufacturing process, which is not preferable in the environment. On the contrary, if the addition amount is 0.02% by weight or less, a sufficient repellent effect is not observed, which is not preferable. The preferred amount of lemongrass oil added is 0.08-
It is 0.2% by weight.

The addition amount of the creosote is 0.0
The range of 2 to 0.3% by weight is such that even if 0.3% by weight or more is added, the repellent action and antiseptic / sterilizing action cannot be expected further, and it is economically unfavorable. Unnecessary odor is generated in the garbage bag manufacturing process, which is not preferable for the environment. On the contrary, if the added amount is 0.02% by weight or less, the repellent action and the sufficient effects of antiseptic and sterilization are not observed
This is because it is not preferable. The preferable addition amount of creosote is 0.08 to 0.2% by weight.

[0015]

According to the garbage bag of the first aspect of the invention, small animals such as dogs and cats do not like the odor generated by the lemon grass oil and / or creosote chemicals contained in the synthetic resin sheet. It was obtained as a result of discovering that there are properties, and by incorporating at least one of these chemical substances in the synthetic resin sheet that constitutes the garbage bag,
It prevents small animals such as dogs and cats from approaching the garbage bags.

Further, this lemongrass oil has a strong aroma of lemon odor, and creosote emits a faint medicinal odor (for example, a odor resembling a thin deodorant (registered trademark)), which is different from the conventional one. It is a desirable odor for humans.

Moreover, since creosote has a strong antiseptic and sterilizing action, it can effectively suppress the odor and putrefaction of food waste stored in a garbage bag.

[0018]

[Examples] The garbage bags of the present invention were formed according to the production methods of Examples and Comparative Examples described below, and an outdoor standing test was conducted to investigate the leaning condition of stray cats in these bags.

Lemongrass oil kept at room temperature was added to the molten bottom density polyethylene so as to have the respective addition amounts shown in Table 1 to prepare a film raw material.

This film raw material was heated at 150 ° C.
After forming an inflation film having a diameter of 65 cm and a thickness of 30 μm, it was cut into a length of 80 cm and the lower end was heat-sealed to form a bag.

Each of the obtained garbage bags was subjected to the following outdoor standing test. Table 1 shows the results.

For each test, each bag of the present invention and the bag of the comparative example were prepared, one raw fish was put in each bag, the upper end was tightly bound, and the cat was infested outdoors. These bags were arranged and allowed to stand for one day and night, and it was observed that the bags were eaten by the cat. Such a test is conducted five times,
The average value is shown in Table 1.

Observation of whether or not the bag was broken was made by visual observation, and the judgment was made in two stages, that is, the state where the bag was not broken at all and the state where it was broken. In the table, ◯ indicates that the bag was not broken at all, and x indicates that it was broken.

As is clear from the description in Table 1, Example 1
In all of the tests, the bags did not break through until the second day in any of the tests, and a sufficient repellent effect was exhibited, showing good results. In Comparative Examples 1 and 3, the amount of lemongrass oil added was Since the amount was small or was not added at all, all were broken on the first day, and a sufficient repellent effect was not exhibited. Further, Comparative Example 2 exhibits the same repellent effect as that of Examples 2 to 4, but the addition amount is large, the cost is high, and the odor is generated more than necessary. The repellent effect could not be expected, which was not preferable.

As is clear from these results, when a synthetic resin film was made to contain lemon grass oil as an odor component and a dust bag was formed with this film, the effect of preventing leaning of stray cats was obtained.

Next, the garbage bags of the present invention were formed by the production method of Examples and Comparative Examples described below, and an outdoor standing test and a rotting odor test were conducted to investigate the leaning condition of stray dogs in these bags. .

To the melted bottom density polyethylene, creosote kept at room temperature was added in a weight ratio shown in Table 2 to prepare a film raw material.

This film raw material was heated at 150 ° C.
After forming an inflation film having a diameter of 65 cm and a thickness of 30 μm, it was cut into a length of 80 cm and the lower end was heat-sealed to form a bag.

Each of the obtained garbage bags was subjected to the following outdoor standing test and rotten odor test. The results are shown in Table 2.

For each test, the bag of the present invention and the bag of the comparative example were prepared, and one raw fish was placed in each bag, and the upper end was tightly bound, and these were placed in the field where dogs appear and disappear. The dogs were lined up and left for one day and night, and the situation in which the dogs ate the bags and the decay of raw fish was observed. 5 such tests
I went over. Table 2 shows the results.

Whether or not the bag was broken was visually observed, and it was judged in two stages, that is, the bag was not broken at all and the bag was broken. In the table, ◯ indicates that the bag was not broken at all, and x indicates that it was broken.

To determine the state of rotting, the bag is collected, the upper end of the bag is opened, and the rotting odor emitted from the mouth of the bag at that time is sniffed. A judgment was made. ○ indicates that there was no rotten odor. △ is a state with a slight rotten odor. × is a state where raw fish is putrefaction and gives off a strong putrid odor.

As is apparent from the description in Table 2, in terms of repellent action, Examples 5 to 8 show sufficient repellent action in all the tests without the bag being eroded by the second day. Comparative Example 4
In Nos. 6 and 6, since the amount of creosote added was small or not added at all, they were broken in the first day, and a sufficient repellent effect was not exhibited. In addition, Comparative Example 5 exhibits the same repellent effect as that of Examples 6 to 8, but the addition amount is large, the cost becomes high, and odor is generated more than necessary. The repellent effect could not be expected, which was not preferable.

Regarding the anti-rot action, no rotting odor was observed by the second day in any of Examples 5 to 8, and Example 5 had a slight odor on the third day and was completely odorous from the fourth day. It turned out to be corrupt. Further, in Examples 6 to 8, no rotten odor was observed until the 3rd day, and the odor was slightly felt on the 4th day.
From the day onward, it was found to rot completely, and sufficient antiseptic / sterilizing action was exhibited, showing good results. However, in Comparative Examples 4 and 6, the amount of creosote added was small, or no creosote was added at all. Therefore, it was found that the odor of putrefaction was produced from the first day, and the putrefaction preventive action was not sufficiently exerted. . Further, Comparative Example 5 exhibits the same anti-corrosion action as that of Examples 6 to 8, but a large amount is added, the cost is high, and odor is generated more than necessary. The above antiseptic / sterilizing action cannot be expected, which is not preferable.

As is clear from these results, when a synthetic resin film contains creosote as an odor component and a dust bag is formed from this film, the effect of preventing leaning of stray dogs is obtained, and It was found that it has an antiseptic / sterilizing effect on food waste stored in the garbage bag.

Further, a garbage bag according to the present invention was formed by the production method of the following Examples and Comparative Examples, and an outdoor standing test and a rotting odor test for investigating the leaning condition of stray cats and stray dogs against these bags were conducted. Carried out.

Lemongrass oil and creosote, which were kept at room temperature, were added to molten bottom density polyethylene.
The raw materials for the film were prepared by adding them in the weight ratio shown in.

This film raw material was heated at 150 ° C.
After forming an inflation film having a diameter of 65 cm and a thickness of 30 μm, it was cut into a length of 80 cm and the lower end was heat-sealed to form a bag.

Each of the obtained garbage bags was subjected to the following outdoor standing test and rotten odor test. Table 3 shows the results.

For each test, the bag of the present invention and the bag of the comparative example were prepared, one raw fish was placed in each bag, and the upper end was tightly bound to the field where dogs and cats appear and disappear. After arranging these bags for one day and night, the bag was eaten away by dogs and cats, and the spoilage of raw fish was observed. Such a test was performed 5 times. The results are shown in Table 3.

Whether or not the bag was broken was visually observed, and the bag was judged in two stages, that is, the bag was not broken at all and the bag was broken. In the table, ◯ indicates that the bag was not broken at all, and x indicates that it was broken.

To determine the state of rotting, the bag is collected, the upper end of the bag is opened, and the rotting smell emitted from the mouth of the bag at that time is sniffed. A judgment was made. ○ indicates that there was no rotten odor. △ is a state with a slight rotten odor. × is a state where raw fish is putrefaction and gives off a strong putrid odor.

As is clear from the description in Table 3, Example 9
Nos. To 12 can obtain the same results as the experimental results shown in Table 1 and Table 2 above, and Comparative Examples 7 to
For 9 as well, results similar to those shown in Tables 1 and 2 above were obtained.

As is clear from the above results, when a synthetic resin film contains lemongrass oil and creosote and a trash bag is formed from this film, it is possible to effectively prevent leaning of both dogs and cats. Besides,
It was also found to have the effect of successfully suppressing the decay of the contents and the odor emitted from it.

[0045]

As described above, according to the garbage bag of the present invention, small animals such as dogs and cats can be kept away from each other for at least 2 days due to the odor emitted from the synthetic resin. Therefore, even if you put garbage in this garbage bag on the day of garbage collection and take it out, at least a few hours to 6 hours before the cleaning car comes to the garbage collection, there is no risk that small animals will eat away the garbage bag. Also, there is an advantage that the garbage contained therein, especially the garbage etc., is less likely to be decomposed easily and can further contribute to avoiding small animals such as dogs and cats.
