Description

  The present invention relates to a plastic bottle garbage bag in which a plastic bottle can be separated into a bottle body and a cap.

In recent years, separate collection of trash has been recommended and implemented by local governments for the purpose of improving the efficiency and recycling of trash.
Among these, PET bottles widely used as containers for soft drinks are treated as important resources that can be recycled into various items such as textiles and household items after use.
When disposing of used PET bottles as trash (disposal), it is common to remove the cap from the bottle body and separate and collect the bottle body and cap separately. In this case, the bottle body is a dedicated PET bottle. The cap is accommodated in the combustible garbage bag as normal combustible garbage.

  In order to be able to determine that a conventional plastic bottle garbage bag is a plastic bottle garbage bag, the characters “for plastic bottles” are printed on the surface of the bag, or the color of the bag and the printing color are changed. Structurally, like a known garbage bag, it was formed into a garbage bag made of a plastic cylindrical body having an opening at one end and a bottom at the other end.

In addition, although the thing which provided the perforation along the upper side edge of a garbage bag is known as a garbage bag for PET bottles (refer patent document 1), this garbage bag has a garbage bag main body by a division seal part. The bottle body and cap are separated and separated into a large-capacity bag portion that is a bottle body housing portion and a small-capacity bag portion that is a cap housing portion having a smaller capacity than the large-capacity bag portion. There is no description of the structure to be made, and its purpose and structure are completely different from the garbage bag for a plastic bottle of the present invention.
Japanese Patent Publication No. 2005-219841

In this way, when separating and collecting PET bottles into a bottle body and a cap, the bottle body can be stored in a dedicated plastic bottle garbage bag, but the cap does not have a dedicated garbage bag, so it is combustible. It is thrown away in a garbage bag.
For this reason, in order to dispose of plastic bottles as trash, two separate trash bags, a bottle trash bag and a cap trash bag, are required, and there is no cap trash bag nearby. However, there is a problem that it takes a troublesome work to take the cap removed from the bottle body to the place where the garbage bag for the cap is placed and to discard it there.

The present invention allows the trash bag body to store the bottle main body storage portion and the cap storage portion so that the bottle main body and the cap can be stored separately in a single trash bag, The separation and storage work can be done using a single trash bag so that the troublesome task of throwing away the cap removed from the bottle body into another trash bag can be saved. To do.
It is another object of the present invention to provide a plastic bottle garbage bag that can separate the bottle main body and the cap from the bottle main body storage and the cap storage.

In order to solve the above problems, a garbage bag for a plastic bottle of the present invention (Claim 1)
A partition seal extending from the opening edge (20) to the bottom edge (30) to the garbage bag body (1) by a cylindrical plastic film having an opening (2) at one end and a bottom (3) at the other end. Part (4) is formed at a position offset to one side of the garbage bag body (1),
A large capacity bag portion (1a) in which the garbage bag main body (1) is a bottle main body accommodating portion and a small cap accommodating portion having a smaller capacity than the large capacity bag portion (1a) by the partition seal portion (4). It is divided into a capacity bag part (1b),
A perforation line (5) for separating the large-capacity bag portion (1a) and the small-capacity bag portion (1b) is formed in the partition seal portion (4).

  In addition, the code | symbol in the said parenthesis shows a corresponding relationship with the specific means described in the Example mentioned later.

The plastic bottle garbage bag of the present invention is divided into a large-capacity bag portion in which the garbage bag main body is a bottle main body accommodating portion and a small-capacity bag portion that is a cap accommodating portion having a smaller capacity than the large-capacity bag portion. Yes.
Therefore, when throwing away PET bottles as garbage, place the PET bottle garbage bag of the present invention at hand, store the cap removed from the bottle body in the small-capacity bag part, and place the bottle body with the cap removed in the large-capacity bag part Can be accommodated.
That is, the bottle body and the cap can be stored separately in a single garbage bag, and the separation and storage operation can be performed using a single garbage bag placed at hand, This saves you the trouble of going to throw away the cap removed from the bottle body into another garbage bag.

In addition, when disposing (removing garbage) from each household, the large-capacity bag portion (bottle main body storage portion) and the small-capacity bag portion (cap storage portion) can be separated by a perforation line.
That is, when the bottle main body storage portion and the cap storage portion are full, if the bottle main body storage portion and the cap storage portion are separated by the perforation line, the bottle main body is stored in a dedicated garbage bag. Separately, the cap is housed in a dedicated garbage bag, and the bottle body and the cap can be separately collected.

Currently, most local governments dispose of caps as combustible waste, so the small-capacity bag portion (cap housing portion) that contains the cap is placed in a combustible waste bag and discarded (trash out). However, the material of this cap is polypropylene, and technologies such as recycling as building materials have been developed.
Therefore, in the future, it may be possible to collect the cap not as combustible waste but as a recycled resource. In such a case, the cap is stored (waste out) with the small-capacity bag portion (cap housing portion) accommodated. It is also possible.
In addition, when disposing of (disposal of garbage) from each household, without separating the bottle main body storage portion and the cap storage portion by the perforation line, it is discarded while being connected via the perforation line, and after collecting this, You may make it isolate | separate into a bottle main body accommodating part and a cap accommodating part by a perforated line by the hand of a collector or a recycler.
