  The two composting bags shown in the above patent document are both inventions of the applicant. Each of these bags is provided with a net-like cylindrical main body and a bottom surface, and a lid that can be opened and closed with a fastener or the like is provided on the upper side.

  In order to use a known composting bag, first, it is installed in a place where there are many fallen leaves in late autumn or early winter, and dead leaves, fallen leaves, dead branches, etc. are put in one after another with the upper lid open. When the contents are full, the input operation is once stopped and left unattended. If this is left outdoors, compost will be completed in about May to June.

  By the way, the conventional composting bag was invented for the purpose of business use and has a large capacity. In addition, since compost is produced from the bottom, there is a difficulty that if the fermented fertilizer is used, it must be removed from the bottom. In order to solve this problem, in Patent Document 1, a hook is provided on the bottom surface, and all the compost is taken out by lifting it upside down with a crane or the like. However, this is a large-scale work, and the upper portion of the compost that has not been fully fermented is taken out at the same time, leaving a problem in the use of compost.

  In view of the above circumstances, the present invention proposes a bag in which only fully fermented compost in the lower layer of the bag can be easily taken out in this type of composting bag.

  In order to solve the above-mentioned problems, the present invention is a bag comprising a bottomed cylindrical body made of a material having air permeability and water permeability, and an upper lid that opens and closes its upper surface opening so as to be openable and closable. Adopted a means for providing a composting bag by providing an opening / closing door that can be opened and closed by an opening / closing tool on the lower edge of the side peripheral surface of the opening and forming an opening whose one side coincides with the lower edge. .

  Compost with dead leaves and fallen leaves turned into fermented soil is fermented and matured from the bottom of the bag, so an open / close door is provided at the lower edge of the side surface to remove only the lower layer compost from the opening. It became possible.

  The opening / closing door employs a means that can be opened and closed by forming an opening that opens from the bottom to the top with a fastener provided in a substantially U shape.

  In addition, the open / close door employs a means that can be opened and closed by forming an opening that opens from the top to the bottom with a fastener provided in an inverted U shape.

  By making the opening / closing door freely openable and closable with a fastener, the door can be easily opened and closed, and durability and convenience can be obtained depending on the opening direction.

  And the hoop ring was each attached to the vicinity of the upper edge and lower edge of the said trunk | drum, and the means of attaching a some support rod to the orthogonal | vertical direction of the trunk | drum side peripheral surface was employ | adopted.

  Since the bag itself can stand on its own, it can be installed outdoors as it is so that dead leaves and fallen leaves can be introduced. Even when the compost is taken out from the lower edge, it can be operated as it is.

  The composting bag of the present invention according to the above configuration is provided with an opening / closing door whose one side of the opening coincides with the lower edge on the lower edge of the trunk side peripheral surface, so that the bag is sequentially from the bottom of the bag. Of the compost that matures, only the lower layer compost can be easily removed from the opening, and it does not require large-scale work such as lifting the bag upside down as in the past, increasing convenience. is there.

  And since a dead leaf and a fallen leaf are composted, it can compost without discarding the dead leaf etc. which were conventionally disposed as garbage. Therefore, it is an excellent device that can reduce the amount of waste and the cost of disposal. In addition, since the compost that has been made can be used for growing trees, it can contribute to recycling.

  Moreover, it can utilize as a composting bag excellent in durability and convenience by selecting the opening and closing direction of the door.

  In addition, because it is self-supporting, it can be installed as it is, and dead leaves and fallen leaves can be input, and even after the compost has matured, the compost can be taken out from the side surface while it is self-supporting. Use is promoted.

It is a perspective view of the embodiment of the bag for composting concerning the present invention. It is a perspective view of other embodiment.

  Hereinafter, preferred embodiments of a composting bag according to the present invention will be described with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a bottomed cylindrical body portion of a composting bag, which is formed by appropriately sewing a material having air permeability and water permeability such as mesh ground into a bag shape. Reference numeral 2 denotes an upper lid that closes the upper surface opening of the body 1 and can be freely opened and closed by a fastener such as a fastener. The upper lid 2 is also made of mesh or the like. By adopting such a mesh ground or the like, fermentation and ripening of the housed dead leaves and fallen leaves proceed.

  Reference numerals 3 and 4 denote hoop rings attached in the vicinity of the upper edge and the lower edge of the body 1, which reinforce the opening and bottom of the body 1 and define the shape of the ring in a circular shape. 5, 5... Are support rods attached to the side peripheral surface of the body portion 1 through appropriate band cloths at appropriate intervals in the vertical direction, and are used to make the entire bag self-supporting in a cylindrical shape. . 6 is a handle for hanging the bag provided on the upper edge of the trunk 1. In addition, this structure is a structure almost common to this type of conventional composting bag, and the self-supporting means is not limited to this.

  Next, reference numeral 7 denotes an opening / closing door provided on the lower edge of the side peripheral surface of the body portion 1, which can be freely opened and closed by an opening / closing tool 8 such as a fastener. In FIG. 1, the open / close door 7 is provided with a substantially U-shaped fastener having a pair of runners facing each other on the remaining three sides, leaving an upper side of a rectangle, and forms an opening that opens from the bottom to the top. The opening is provided so that one side of the opening coincides with the lower edge of the body side peripheral surface. And the lower edge part of the side peripheral surface of a bag can be open | released largely by raising this opening-and-closing door 7 upwards. In addition, although the aspect which raised partially is shown in the figure, it opens fully at the time of use.

  The composting bag having the above configuration is installed outdoors, and the upper lid 2 is opened, and dead or fallen leaves are filled until they are full. Then leave it alone. If it does so, since the whole bag is comprised with the raw material which has air permeability and water permeability, fermentation and ripening will advance by the effect | action of an aerobic microbe in the ground, and a fallen leaf and a dead leaf will gradually become humus soil, and bulk will become low. Then, again, the dead and fallen leaves are thrown in until full. By repeating this for several months, humus is accumulated in layers in the bag and can be used as compost. At this time, since the lower layer is sufficiently fermented, it is preferable to use the lower layer. The composting bag according to the present invention is self-supporting and, as described above, provided on the lower edge of the side peripheral surface of the trunk portion 1 with an opening / closing door whose one side coincides with the lower edge. Therefore, by opening this, only the fully fermented humus deposited in the lower layer can be taken out from the opening, and can be used as compost.

  Next, FIG. 2 shows another embodiment of a composting bag according to the present invention. In this embodiment, the basic configuration of the bag is the same, but the configuration of the door is different. That is, in FIG. 2, the open / close door 9 is provided with a reverse U-shaped fastener 10 in which a pair of runners face each other on three sides excluding the lower side of the rectangle to form an opening that opens from top to bottom. It can be opened and closed freely. In this case, the side peripheral surface of the bag body portion can be largely opened to the lower edge by fully opening the fastener. And like the above, the compost deposited in a lower layer can be taken out from an opening part, and can be used.

  As described above, in the above two embodiments, it is common to provide the opening and closing doors 7 and 9, but there are differences in the opening and closing directions. Normally, it takes a long time for the dead leaves, etc., put in the bag to become compost. During this time, the compost settles and the body part becomes inflated or swelled and hardens. Pressure is applied. At this time, since the fastener portion is slightly weaker than the bag portion, an inverted U-shaped opening / closing door whose lower side is the bag portion is more preferable to prevent failure from the fastener portion. On the other hand, when the upper side of the former is a substantially U-shaped opening / closing door with a bag, the bottom edge portion can be opened without fully opening the door, which is convenient for taking out the lower layer compost. As described above, since there are advantages in durability and convenience, depending on the size of the bag, that is, the amount of compost that can be formed, the direction of the open / close door can be selected as appropriate. . In addition to the above, it is also possible to provide an opening / closing door in the lateral direction, that is, in a U-shape.

  As described above, the composting bag according to the present invention is made into compost by putting dead leaves and fallen leaves into it, so it is installed in places where there are many trees and lots of dead leaves, such as parks, green spaces, schoolyards, etc. Thus, it can be composted without disposal of dead leaves and the like that have been disposed of as waste. This greatly contributes to reducing the amount of waste, and can reduce the cost of collecting and transporting the waste, and at the same time, contributes to the recycling of the trees by growing the compost. And when using the compost, it is possible to take out only the fully fermented compost that accumulates in the lower layer of the bag from the opening, so that the compost is taken out by hanging the bag upside down as usual. It is a highly convenient device that does not require extensive work.
