Description

[Detailed Description of the Invention] The present invention relates to a lid for a compost maker.

Various types of composting containers have been proposed and used for the purpose of recycling resources by composting food waste and garden waste generated in everyday homes. For example, there is a nearly cylindrical compost container that has an upper opening and a bottom opening. By adding garbage and piling it up (sometimes adding soil as the case may be), the waste is composted and can be used as garden fertilizer or home garden fertilizer. However, in this type of compost production container, maggots and the like may occur, especially in the summer, and these maggots may climb up the side wall of the container body and come out of the container. Alternatively, the liquid may stick to the bottom of the lid that closes the upper opening and fall out of the container when the lid is removed, creating an unsanitary condition. Conventionally, in order to prevent this, a structure has been proposed in which a so-called maggot barb is formed on the upper inner wall of the container body to repel maggots and the like that climb along the inner wall downward. There is.
However, this type of container body is manufactured by integral molding from plastic material and is quite large, so providing a special barb on the inner wall would complicate the molding accordingly. Moreover, the amount of plastic material used also increased, resulting in an increase in the overall price.

The purpose of the present invention is to provide a lid for a compost production container that can prevent the discharge of maggots and the like and is inexpensive overall. be.

According to the present invention, in a lid for closing the upper opening of a substantially cylindrical compost production container having an upper opening and a bottom opening, the lid protrudes into the internal space of the compost production container when attached to the upper opening. A convex wall extending downwardly along the bottom circumference is provided so as to do so.

Next, the present invention will be described in more detail with regard to embodiments of the present invention based on the accompanying drawings.

FIG. 1 is a perspective view showing a compost production container using a lid as an embodiment of the present invention. FIG. 2 is a sectional view taken along line A-A' in FIG. As shown in FIGS. 1 and 2, the compost production container main body 10
For example, it is integrally molded from a plastic material and is a substantially conical cylinder having an upper opening 11 and a bottom opening 12. The top opening 11 of the compost container main body 10 is fitted with a compost container lid 20 according to the present invention for closing the top opening 11.

FIG. 3 shows this lid 20 for compost manufacturing container in a front view, FIG. 4 shows this lid 20 in a bottom view, and FIG. It is a diagram. As shown in FIGS. 3, 4, and 5, the compost container lid 20 can be integrally molded from the same plastic material as the compost container main body 10, and the circumference of the bottom 21 is It has a convex wall 22 extending downward along.

The fitting between the compost manufacturing container lid 20 and the compost manufacturing container main body 10 is achieved by inserting the lid 20 into the recess 13 provided at the periphery of the upper opening 11 of the compost manufacturing container main body 10, as shown in the partial perspective view of FIG. As shown in FIGS. 3 and 4, insert the compost container lid 2 into the upper opening 11 of the compost container main body 10 so that the convex portion 23 provided on the side of the compost container lid 20 is aligned.
0, then rotate the compost manufacturing container lid 10 with respect to the compost manufacturing container main body 10, and insert the recess 1 into the recess 1.
3 and the convex portion 23 are shifted from each other. When removing the compost production container lid 20 from the compost production container main body 10, conversely,
Rotate the lid 20 relative to the main body 10 to remove the convex portion 23
At the position where the and recess 13 meet, insert the lid 20 into the main body 1.
All you have to do is pull it out from 0.

As described above, when the lid 20 is attached to the upper opening 11 of the container body 10, the convex wall 22 of the lid 20 is inserted into the internal space of the container body 10, as clearly shown in FIG. protrudes to.

The compost production container main body 10 having such a structure is installed so that its bottom opening 12 faces into the soil,
By putting food waste, garden waste, etc. into the container body 10 and accumulating it, the garbage can be composted, but maggots may occur inside the container body 10, especially in the summer. There is. The maggots climb up the side wall 14 (see FIG. 2) inside the container body 10. It then moves on to the side wall 24 of the lid 20 that closes the upper opening 11 of the container body 10, and further extends to the outer periphery of the convex wall 22, which protrudes vertically downward. Therefore, the maggots cannot pass over the tip 22A to the bottom 21 of the lid 20 and fall into the container body 10 from the tip 22A. Therefore, maggots will not attach to the bottom 21 of the lid 20.

Since the composting container lid of the present invention has the structure described above, maggots generated inside the composting container can come out of the container without having to provide maggot barbs toward the composting container. It is possible to completely prevent unsanitary conditions such as dripping or getting stuck on the back of the lid and being thrown out of the container when the lid is removed. Furthermore, since the compost container lid is small compared to the compost container main body, even if a convex wall is added as in the present invention, it is relatively easy to use and can be made of plastic material. It can be manufactured without significantly increasing the quantity, and therefore the price of the compost manufacturing container as a whole does not increase.
